Introduction The risk of exposure to M. tuberculosis among healthcare workers (HCW) remains a public health concern worldwide. During the COVID-19 pandemic, the Biomedical Research and Training Institute supported the Zimbabwe Ministry of Health and Child Care in strengthening infection prevention and control (IPC) practices in healthcare facilities (HCF), integrating tuberculosis (TB) infection control (TBIC) into the intervention strategy. We describe the impact of this intervention on TBIC practices and HCW screening outcomes. Methods The strategy, implemented from June 2021–September 2022, included IPC mentorship training, competency assessments, and use of a standardized risk assessment tool for progress monitoring. For the training purposes, the project developed eight practical problem-solving IPC modules including an occupational health component. Trained mentors conducted bi-monthly site support visits (SSV), used a checklist to track compliance, and assessed competencies of HCW at the targeted facilities. Facility-based risk assessments were conducted three times during the project implementation. Results During the intervention, 1,865 HCW from 105 facilities were trained. Availability and use of personal protective equipment improved by 49% and 42%, respectively. The proportion of HCF with designated areas for sputum collection increased by 43%. The proportion of HCF that screened HCW for TB increased by 42% with 3,761 HCW screened during the project period. Fourteen were diagnosed with TB and referred for care, resulting in 372 new cases per 100,000. Conclusion The implemented strategy of training, mentorship, and regular SSV strengthened TBIC measures, improved TB screening practices and case finding among HCW. Improving and maintaining practices is critical for effective TBIC.

Cervical cancer is the fourth most common cancer in women globally, with 660,000 new cases and 350,000 deaths in 2022. The burden is disproportionately high in low- and middle-income countries (LMICs), particularly sub-Saharan Africa. Despite proven interventions like HPV vaccination and screening, uptake remains low. While cervical cancer screening has been studied in the general population, little is known about uptake among refugee women in Uganda, which hosts approximately 1.7 million refugees. This study examines cervical cancer screening uptake and associated factors among refugee women in Uganda. Methods We conducted a cross-sectional secondary analysis of the 2021 Uganda Refugee Population-based HIV Impact Assessment (RUPHIA) survey, focusing on women aged 21–49 in refugee settlements in the West Nile and South-Western regions, which host 90% of Uganda’s refugee population. The primary outcome was self-reported cervical cancer screening status. We used descriptive statistics and logistic regression to identify factors associated with screening uptake. Results Among 731 women, only 72 (9.8%) reported undergoing cervical cancer screening. The mean age of screened women was 37 years (±7), compared to 32 years (±8) for unscreened women. Screening uptake was significantly higher among women aged 31–39 years (AOR = 2.67, 95% CI: 1.32–5.52, p = 0.007), married women (AOR = 12.0, 95% CI: 1.76–163, p = 0.03), and those in polygamous relationships (AOR = 4.76, 95% CI: 1.96–11.1, p < 0.001) Conclusion Cervical cancer screening uptake among refugee women in Uganda is critically low. Integrating culturally sensitive screening programs into refugee health services and addressing socio-economic barriers could improve access and utilization.

Colorectal cancer (CRC) is a major public health problem worldwide, as it is the third most common disease and the second leading cause of cancer-related fatalities. In recent years, Oman, like many other countries, has seen an epidemiological shift from communicable diseases to noncommunicable diseases, including colorectal cancer, necessitating comprehensive planning to address the root cause of the problem as well as a comprehensive screening program to detect diseases at an early stage and thus improve health outcomes. Colorectal cancer is the second most frequent cancer in Oman, with the highest mortality rate, inflicting considerable public health and economic consequences; nevertheless, there is no population-based CRC screening programme in place to minimise the disease's incidence, mortality, and severe health outcomes. This review highlights the epidemiology of colorectal cancer in Oman, the Wilson and Junger criteria, operational readiness, and recommendations for implementing a population-based colorectal cancer screening program.

Background Nearly 40% of the adult population in the United States are considered obese by current standards, which equates to approximately 93 million people. Obesity is a chronic disease that is linked to more than 40 other diseases, including hypertension, heart disease, stroke, diabetes, and at least 13 distinct types of cancers. The direct and indirect costs of obesity have been estimated at up to $210 billion annually. Local Problem In Cumberland County, North Carolina, 34% of the adult population was considered obese. The aim of this quality improvement study was to increase effective care (screening, patient engagement, and referral to treatment) in adult patients with a BMI greater than 30 kg/m2 to 75% within 90 days. Methods A rapid cycle plan-do-study-act framework was used to evaluate four focus areas concurrently over 8 weeks with a small test of change completed in each 2-week cycle. Interventions An expanded screening with a checklist, shared decision-making tools (SDMTs), and a referral to treatment checklist were implemented. Activities from the team engagement plan were initiated. Results The effective care of patients increased by 42 percentage points while engaging both the patients and the staff. Conclusions Utilizing standardized communication, SDMTs, checklists, and management plans improved effective care while motivating and enabling patients to take control of their care and make sustainable lifestyle changes that enhance overall health.

In Niger, sorghum (Sorghum bicolor) is one of the most important staple crop for food and money. Despite the importance of the crop and its easiest adaptative capacity to dry, the crop is confronted to striga (Striga hermonthica), a plant parasite, which drastically hinder the productivity and causing yield loss between 20% to 80%. The best and easiest way to control and improve sorghum productivity is through the development of novel Striga resistance sorghum genotypes. The purpose of this study was to assess 20 sorghum genotypes from diverse country for striga resistance and grain yield capacity. Varieties with high yield average, medium size and resistance to Striga were found.

Although pre-exposure prophylaxis (PrEP) is highly effective at preventing HIV infection, only around 25% of at-risk individuals in the United States have accessed a prescription. One way to increase PrEP uptake is through the sexual health screening of patients and linkage to PrEP in primary care settings. The objective of this analysis was to assess the barriers and implementation strategies during a screening and linkage to PrEP pilot intervention. Primary care patients were screened for PrEP indication during routine primary care visits. Of the 1,225 individuals screened, 1.8% (n=22) were eligible for PrEP and from those, 77.3% (n=17) attended the specialist appointment and were prescribed PrEP. Primary care patients (n=30) and providers (n=8) then participated in semi-structured interviews assessing their experience with the pilot intervention. Using an applied thematic analytic approach, patients and providers identified barriers and related improvement strategies that could be classified into four main categories: 1) Financial Barriers: Individual- vs. Clinic-level Considerations 2) The Role of Stigma, Discomfort, and Cultural Factors 3) Logistical Hurdles and Streamlining the Intervention, and 4) The Lack of PrEP Knowledge and the Need for Education. Findings support the accepatability and feasibility of screening for PrEP in primary care along with appropriate implementation strategies. This study suggests that because of the high volume of patients seen in primary care, sexual health screenings and linkage to PrEP interventions have the potential to reduce new incident HIV infections among diverse sexual minority men.

Using samples of small cell lung tumors, a research team led by biologist Dr. Raymond discovered two new ways to induce tumor cell death. By activating ferroptosis, one of two subtypes of tumor cells can be targeted: first, iron-dependent cell death due to oxidative stress, and second, oxidative stress. Therefore, cell death can also be induced in a different way. Both types of cell death must be caused by drugs at the same time to eliminate the majority of the tumor mass. It is currently in clinical trials for cancer treatment. Auranofin, which inhibits the production of protective antioxidants in cancer cells, has been used to treat rheumatoid arthritis for decades. Future clinical trials using this combination therapy will determine the extent to which this targeted treatment option improves the prognosis of small cell lung cancer patients. It is currently in clinical trials for cancer treatment. Lung cancer is the leading cause of cancer death in the United States. Despite evidence of molecular abnormalities in biological specimens, progress in this disease is hampered by the lack of diagnostic markers useful for clinical practice. The majority of patients with lung cancer are still diagnosed at an advanced stage, when prognosis is poor. This article reviews new strategies being studied for the early detection of lung cancer. These strategies involve new methods of imaging (including low-dose computed tomography CT scanning), DNA analysis, and proteomic-based techniques. These strategies have not only improved our understanding of lung cancer but show promise in offering better survival to patients with this deadly disease. Of paramount importance in the search for methods of early detection is the need for the identification of the ideal population to screen, a multidisciplinary approach, and validation of promising techniques.

Background Eighty five percent of cervical cancer occurrence in resource-poor countries. Contributing factors for these are inadequate knowledge about the disease, early initiation of sexual intercourse and multiple sexual partners. Early screening is an intervention in reduction of maternal deaths due to cervical cancer. Consequently this study was conducted aiming to find out about the practice of cervical cancer screening and its associated factors. Methods A facility based cross sectional study was conducted using a pretested structured questionnaire among women attended Maternal and Child Health (MCH) department of Felege Hiwot Referral Hospital (FHRH) from March15 to April 15, 2019. The study participants were selected systematically. The collected data were entered and analyzed using SPSS version 20. Logistic regression analysis was employed to examine factors association with cervical cancer screening that was confirmed using AOR with its 95% CI. Results A total of 400 study participants were included with a response rate of 99.5%. Of the total study participants only 78 (19.5%; 95% CI: 15.6, 23.4) practiced screening for cervical cancer. The cervical cancer screening practice was affected by age (AOR=2.025; 95% CI: 1.118, 3.668). Of those women who had ever heard of about cervical cancer were seven fold more likely to practice cervical screening (AOR=6.924; 95% CI: 1.602, 29.928) compared to those who did not have any information before. Moreover, knowing genital tract discharge as a problem of female organ implement fourfold more likely compared to that of knowing nothing about problem of genital tract (AOR=3.766; 95% CI: 1.761,8.055). Conclusion and Recommendation The study depicted there was low utilization of cervical cancer screening. Awareness creation about cervical cancer and knowledge of genital tract problems had positive influence for screening practice.

Objective Real-time surveillance of SARS-CoV-2 variants of concern (VOC) is of essential public health importance. Rapid Antigen Detection Tests (RAgDT) have become first-line COVID-19 diagnostic methods in many regions, but this strategy can hamper the surveillance of the virus variants due to their decentralized performance. The aim of this study was to assess the usefulness of the remaining sample of a widely used RAgDT (Panbio) for the surveillance of the B.1.1.7 VOC using molecular methods. Methods Symptomatic individuals and asymptomatic close contacts of confirmed cases were routinely screened for SARS-CoV-2 infection using the RAgDT in Primary Health Care Centers. After performing the test, the extraction tubes containing the remaining biological material of RAgDT-positive cases were sent to the clinical microbiology laboratory where RT-PCRs detecting key mutations of the VOC were conducted. Results A valid result was obtained in 1770/1812 (97.7%) RAgDT-positive cases. Variant B.1.1.7 was detected in 34.7% of the patients, increasing from 0% to 87.7% between the weeks beginning January 4 and March 15, 2021. Conclusion The sample remaining after performing the Panbio RAgDT allowed to monitor the emergence and circulation of the B.1.1.7, greatly improving the population screened for the molecular study of SARS-CoV-2 variants.

Background Breast cancer is one of the most common types of cancer affecting women globally. It has shown increasing morbidity and mortality rates over the past years. Several screening methods ranging from simple breast self-examination to a highly sensitive test procedures for early detection and treatment are available, but uptake is a challenge. Lack of a national screening programme in the country makes available regional screening programme unsuccessful. This study aims to assess the factors affecting the uptake of breast cancer screening programme among female staff in a tertiary hospital, Southwest Nigeria. Method This descriptive cross-sectional study involves 375 participants selected by a stratified random sampling technique, with proportional allocation to population size and the use of a semi-structured questionnaire. Respondents were questioned on their basic knowledge of breast cancer symptoms, risk factors and treatment, over a score of 50 and above, were set as the cut-off mark to determine good knowledge of breast cancer. Patients attitudes towards breast cancer screening as well as factors affecting uptake were also measured. Descriptive statistical analysis was done using SPSS-20 while the predictors of the uptake of screening were determined using logistic regression at p ≤ 0.05. Results There were 360 respondents, comprising of 13.3% clinical and 86.7% non-clinical female staff within the age bracket of 20 to 58 years (38.2±0.42 years). Out of the respondents, 97.8% have heard about breast cancer but only 52.3% had been screened while 65.5% had “Good knowledge” of breast cancer. Positive attitude to breast cancer screening was displayed in 52.5% while over 90% claimed to be practicing breast self-examination. Only 36.1% of respondents above 40 years old have had mammography done. Most frequent barriers to screening uptake include cost, poor accessibility to screening facilities, shyness (unfamiliar screener), unavailability of female doctors, careless attitude, fear of cancer and other more pressing family problems. Using logistic Regression at p ≤ 0.05, females with a negative attitude, young unmarried (less than 30years) and lack of easy accessibility to screening facilities were significant factors affecting uptake of breast cancer screening services. Conclusion Due to knowledge-uptake gap of breast cancer screening revealed in this study. It is therefore obvious from these findings that a concerted effort is needed to actively remove these barriers by repeated education, training and re-training strategies among health workers and to improve their uptake and level of advocacy and campaign for breast cancer screening among their patients and clients.

Introduction This study assessed the awareness of cervical cancer screening test among women in the rural area of Imo State. Cervical cancer is the fourth most common cancer and the cause of death in women. The need to ascertain the level of awareness of cervical cancer screening test and the level of uptake among rural women motivated this study. Materials and Methods The study design was cross sectional descriptive survey. The sample for the study, which was statistically determined by Taro Yamane formula was 420. Administered structured questionnaire was used for data collection. Data were analyzed using frequency distribution tables. Results The result showed that 270(64.3%) of the respondents were aware of cervical cancer screening test and only 135(32.1%) used cervical cancer screening test . Majority of the respondents, 400(95.2%) have never taken vaccination for human papilloma virus . The main place where 234(55.7%) of the respondents learnt about cervical cancer screening was the hospital. A good number of the respondents 225(53.6%), had low uptake services because of the views that cervical cancer screening is mainly for the elderly women, and also 140(33.3%) felt that the investigation process is painful. Conclusion Therefore, adequate and substantial measures should be taken to health educate women on benefits of cervical cancer screening tests.

Isolation methods that employ readily-available inexpensive supplies on the open market, which are reliable, as well as economical, such as nucleic acid amplification techniques (NAAT) based on microfluidic technology in low-resource research settings (LRRS) that meets the ASSURED guidelines are essential to develop a noninvasive diagnostic colon cancer screen in stool using micro(mi)RNA molecules. A combination of a microfluidic-based MiRNA stool test with a reliable rolling circle amplification/detection method applied to the quantification of miRNA molecules, result in an affordable sensitive and specific isothermal method for the noninvasive quantitative detection of miRNAs in LRRS. Scientists and engineers have become interested in miRNAs, and they have intensified their efforts to apply emerging simple detection tools to the important bioanalytical challenge of quantifying these small 18-26 nt long molecules. Some of the proposed approaches incorporate novel material, such as simple centrifuges and methods based on microfluidic technology, while others utilize the interesting biological properties of these molecules, such as forming branched RCA structures, allowing for the detection of these biomarker molecules at an attomolar "aM" concentration level, using low cost extraction and isothermal amplification methods in LRRS. We have been interested in studying colorectal cancer (CRC) because it is the 3rd most common malignancy worldwide, and stool can be obtained noninvasively from the patients. We have focused in this research on colon cancer (CC) because it is more common in the USA than rectal cancer (RC). The innovation of our approach lies in the exploratory use of an affordable, quantitative miRNA profiling in noninvasive stool samples in LRRS, whose extracted fragile total RNA is stabilized shortly after excretion from stool by commercially available kits, so it does not ever fragment, followed by quantitative standardized analytical tests that are neither labor intensive, nor require expensive instrumentation, in order to develop apanel of novel miRNA genes for the noninvasive diagnostic screening of early left and right sporadic colon cancers, more economically, and with higher sensitivity and specificity than any other colon cancer screening test currently available on the market. To show the clinical sensitivity and specificity of the proposed quantitative miRNA test using simple methodologies in LRRS,the miRNA results are to be correlated with FOBT, colonoscopy, and pathology data. Standardization establishes test’s performance criteria (sample selection, optimal sample running conditions, preservation and storage), in order to ensure that the assay will perform the same way in any laboratory, by any trained personnel, anywhere in low-resource laboratory settings worldwide.

Prostate specific antigen (PSA) does not provide the high reliability and precision that is required for an accurate screening for prostate cancer (PCa). The aim of our study was to search for a simple, rapid, direct, preferably non-invasive, and highly accurate biomarker and procedure for the screening for PCa. For this purpose the levels of bromine (Br) and zinc (Zn) were prospectively evaluated in expressed prostatic fluid (EPF). Also Zn/Br concentration ratio was calculated for EPF samples, obtained from 38 apparently healthy males and from 33, 51, and 24 patients with chronic prostatitis (CP), benign prostatic hyperplasia (BPH) and PCa, respectively. Measurements were performed using an application of energy dispersive X-ray fluorescent (EDXRF) microanalysis developed by us. It was found that in the EPF of cancerous prostates the levels of Zn and Zn/Br were significantly lower in comparison with those in the EPF of normal, inflamed, and hyperplastic prostates. It was shown that “Sensitivity”, “Specificity” and “Accuracy” of PCa identification using the Zn and Zn/Br levels in the EPF samples were all significantly higher than those resulting from of PSA tests in blood serum. It was concluded that the Zn and Zn/Br levels in EPF, obtained by EDXRF, is a fast, reliable, and non-invasive diagnostic tool that can be successfully used by local, non-urologist physicians at the point-of-care to provide a highly effective PCa screening and as an additional confirmatory test before a prostate gland biopsy.

Background This study aim to assess the factors affecting uptake of cervical cancer screening programmes among female staff of the University College Hospital (UCH), Ibadan in 2014. Method A descriptive cross-sectional study involving 375 participants selected using a stratified random sampling technique with proportional allocation to population size and interviewed using a pre-tested self-administered semi-structured questionnaire. Information on their basic knowledge on cervical cancer were scored to determine good knowledge. Patients’ attitudes toward cervical cancer screening as well as factors affecting uptake were also assessed. Data analysis was done in 2014 using descriptive statistics while screening uptake predictors were determined using logistic regression at p ≤0.05. Results Completed questionnaires were returned by 360 respondents; 13.3% were clinical while 86.7% were non-clinical staff of age range 20 to 58 years (38.2±0.42 years). Majority of the respondents, (95.5%), had heard about cervical cancer with 61.9% having “good knowledge”, but only few (34.2%) had been screened. Averagely, 47.5% displayed positive attitude to cervical cancer screening with Pap smear being the most reported screening procedure. The common barriers to screening uptaking include indecision, inadequate information and feeling of good health. Others were staff hostility, lack of privacy, and cost. Using logistic Regression at p ≤0.05, females with negative attitude and those with children were less likely to uptake cervical cancer screening services. Conclusion The knowledge-uptake gaps of cervical cancer screenings were high as revealed in this study. Therefore, there is a need to further educate eligible women on uptake of cervical cancer screening.

Introduction In France 33% of patients didn’t take care of hepatitis C because there were no diagnosed. Drug injection was main contamination route of hepatitis C virus (HCV) in France. French guidelines were to treat all inmates and drug users, even fibrosis level. Access of HCV screening, care and treatment in drugs users, prisoners and homeless was low in France. They were considered as difficult to treat populations. All these patients need specific support. Hepatitis Mobile Team (HMT) was created in July 2013 to increase screening care and treatment of hepatitis B and C patients. HMT was composed of hepatologist, nurses, social workers and health care worker. Objective increase outreach screening care treatment access and cure of our target population. Patients and methods Target population was drugs users, prisoners, homeless, precarious people, migrants and psychiatric patients. We proposed part or all of our services to our 42 medical and social partners: HCV HBV screening by DBS (dried blood test); outside DBS and FIBROSCAN in converted van; Outreach open center; Drug users information and prevention, Free blood tests in primary care;, Staff training; Social screening and diagnosis; Mobile liver stiffness Fibroscan in site; Advanced on-site specialist consultation; Easy access to pre-treatment commission; Low cost mobile phones for patients; Individual psycho-educative intervention sessions; Collective educative workshops; Peer to peer educational program; Specific one day hospitalizations. All services were free for patients and for partners. Results from 2013 July to 2018 December, we did 8382 DBS for 5382 people (3053 HCV DBS) and 2302 Fibroscan*. HCV new positive rate was 21.3%. Our HCV active file was 651patients included these 24.8% new patients screened by DBS; 98% realized HCV genotype, HCV viral load and FIBROSCAN. DAA treatment was proposed to 96%; 95% started treatment, 4% were lost follow up or refused treatment. After treatment, there was 7 relapse and 3 reinfections by drug injection and cured rate of 94%. Sociological evaluation showed that 4 program qualities for patients: free access, closeness (outside hospital), speed (of the results) and availability (of nurse and social workers). Conclusions: Specific follow-up of drugs users and other HCV high-risk patients including screening, early detection, diagnosis and treatment increase rate of treated and cured patients, with low rate of relapse and reinfections.

There is currently no validated micro(mi)RNA diagnostic stool test to screen for colon cancer (CC) on the market because of the complexity of fecal density, vulnerability of stool to daily changes, and the presence of three sources of miRNAs in stool (cell-free from fecal homogenates, exsosomal miRNAs from fecal exosomes, and fecal colonocytes). To address these complexities, we have first carried out a microarray miRNA experiment, using Affymetrix GeneChip miRNA 2.0 Arrays, on immunocaptured and enriched stool colonocytes of 15 subjects (three healthy controls and twelve colon cancer patients [three TNM stage 0-1 (e.g., polyps◻ ³ 1 cm, villous or tubvillous, or with high grade dysplasia), three stage 2, three stage 3, and three stage 4 in triplicates to select a smaller panel of 14 preferentially expressed mature miRNAs associated with colon cancer (12 Up-Regulated, miR-19a, miR-20a, miR-21, miR-31, miR-34a, miR-96, miR-106a, miR-133a, miR-135b, miR-206, miR-224 and miR-302; and 2 Down-Regulated, miR-143 and miR-145). In a subsequent validation study carried out on total small RNA extracted by immunocapture, followed by RT that employed TaqMan® miRNA Reverse Transcription (RT) Kit and a Custom TaqMan RT Primer Pool, absolute quantification of miRNAs, in copies/µl, was measured using a chip-based Absolute QuantStudio 3D Digital PCR analysis. To ensure that we have chosen human and not bacterial small total RNA, we have carried out coextraction protocols with E. coli K1 strain RS18, compare Agilent electrophoretic patterns, and also sequenced random samples throughout this research using mRNA/miRNA sequencing. Our initial quantitative dPCR miRNA data presented herein showe that the quantitative changes in the expression of a few mature miRNA genes in stool, which are associated with right and left colon cancer, would provide for a more convenient, sensitive and specific diagnostic screening markers thatare more useful than those test markers currently available on the market, such as the low-sensitivity (<15%) fecal occult blood test (FOBT); result in better compliance; and is more economical than the invasive and expensive colonoscopy exam in colon cancer, which can be cured if that cancer is detected at the early TNM stages, and that becomes incurable and deadly if not diagnosed before metastasis. Initial test performance characteristics of the miRNA approach showed that the test has a high numerical predictive value in colon cancer. Moreover, underpinning of the miRNA markers as a function of total RNA showed that the test can numerically differentiate between control subjects and colon cancer patients, particularly at the early stages of that curable cancer. We propose to extend our initial research results to a larger prospective and randomized five-years nested case-control study, to validate the expression of the above 14 miRNAs, in stool of 180 individuals in an epidemiologically designed study, using (30 controls and 150 colon cancer patients (thirty precancerous polyps (stage 0-1), forty five stage 2, and seventy-five colon cancer stages 3 or 4). chosen randomly by an epidemiological method from 900 control and CC subjects to allow for an adequate time to collect the required 900 stool samples, as well as allowing for statistically valid analysis, standardized test conditions, and to provide a mean for determining the true sensitivity and specificity of a miRNA-screening approach in noninvasive human stool. Power-analysis has indicated that a total of 180 individuals, which will take us 5 years to enroll in testing, is an appropriate number of subjects to standardize and validate our proposed miRNA screening test. We may find out at the end of the proposed validation study in stool that fewer miRNAs, or even one miRNA, may suffice to serve as an efficient and a quantitative marker for the non-invasive diagnostic screening of colon cancer in human stool. The above approach when combined with bioinformatics analysis, to correlate miRNA seed data with our previously published messenger (m)RNA target data in stool, allows for a thorough mechanistic understanding of how miRNA genes regulate mRNA expression, and would offer a better comprehensive diagnostic screening test for the non-invasive early detection stage (0-1) of colon cancer. In order to show the clinical sensitivity and specificity of the proposed miRNA test, the absolute miRNA PCR values, in copies/µl, will be correlated with FOBT, colonoscopy, and pathology data. Standardization will establish test’s performance characteristics (sample selection, optimal sample running conditions, preservation and storage) to ensure that the assay will perform the same way in any laboratory, by any trained personnel, anywhere in the World. Ultimately, a smaller number of selected validated miRNAs (<10) showing increased and reduced expression could suffice to give quantitative miRNAs colon cancer expression values, useful for the early diagnostic screening of that curable cancer.

Plastic materials have been used as packaging materials and also have other numerous applications because of their durability and stability. Plastic products are non degradable and they continue to exist in the environment thereby causing a serious threat to the ecosystem. Bioplastics which are biodegradable plastics are emerging out as a boon to overcome the problem of plastic accumulation. Polyhydroxybutyrate or PHB is a bioplastic that serves as an alternative to synthetic plastics. PHB is a lipid reserve material that gets accumulated within the cell wall of micro organisms under stress conditions. Halophilic microorganisms can be of much use in the production of PHB as it is cost – effective and recovery of PHB is much easier in halotolerant organisms. Hence this study focuses on the isolation of PHB producing halotolerant bacterial organisms from marine sources. Screening of PHB positive isolates was done by Sudan Black B and Nile blue A staining. Large scale production of PHB by the efficient bacterial strain was done by using wastewater as the substrate.

Background Despite the existence of the statutory early cancer detection program in Germany and the removal of financial barriers, which is frequently reported in the literature to be the main obstacle in screening, uptake of colorectal cancer screening remains quite low. The campaign for colorectal cancer screening in German companies reported in this article started in 2010. It was initiated because of the low compliance with opportunistic public colorectal cancer screening efforts. Its goal is to improve participation by offering an organized screening program using a simple test (FIT). Methods An offer for company employees is publicized through posters, company newsletters and the intranet. The difference between the positivity rates of those who returned the kits within 20 days and later than 20 days was assessed using the Z-test. The average time between a positive result and colonoscopy was estimated using the Poincaré plot method. The positive predictive values were calculated for carcinomas, advanced adenomas or any lesions. The sensitivity and specificity of immoCare-C published by Vogel et al. and Hundt et al. were used to derive the confidence intervals for the positive likelihood ratio (for carcinoma and any kind of adenoma). Results A total of 312,147 kits were returned and analyzed (return rate 70.2%). 5.6% gave a positive result. The PPV for cancer aged between 55 and 74 was 4.6% for men and women (95% CI: 2.38%-6.76% and 1.28%-7.99%, respectively), but 22% for men (95% CI: 17.93%-26.65%) and 8% for women (95%CI: 3.63%-12.26%) for advanced adenomas. The PPV for any lesion was higher for those with familial risk (49.3%) and 42.6% for those without familial risk (95% CI: 40.2%-45.0%), but with overlapping confidence intervals. Conclusions The reported sample is not representative. Although, offering CRC screening in companies may be an effective way of increasing uptake in the target population. Differences in the test performance between men and women need further evaluation.

Calcium (Ca2+) plays a central role in regulating many biological processes in the cell from muscle contraction to neurotransmitter release. The need for reliable fluorescent calcium indicator dyes is of vast importance for studying many aspects of cell biology as well as screening compounds using phenotypic high throughput assays. We have assessed two of the latest generation of calcium indicator dyes, FLIPR Calcium 6 and Cal-520 AM for studying calcium transients (CaTs) in induced pluripotent stem cell (iPSC) -derived human cardiomyocytes. FLIPR Calcium 6 and Cal-520 dyes both displayed robust CaTs with a high signal-to-noise ratio (SNR) and were non-toxic to the cells. The analysis showed that CaT amplitudes were stable between measurements, but CaT duration was more variable and tended to increase between reads. Two methods were compared for drug-screening hit-selection; difference in average (unstandardized) and standardized difference. The unstandardized difference was better for assessing CaT amplitude, whereas standardized difference was equal to or better for assessing CaT duration. In summary, FLIPR Calcium 6 and Cal-520 are suitable dyes for drug-screening using iPSC-derived human cardiomyocytes.

People living with HIV (PLWH) are at risk of developing chronic lifestyle diseases such as ischaemic heart disease (IHD). Physical inactivity is a modifiable risk factor for IHD. The level of ambulation physical activity in individuals living with HIV in a South African context is unknown. The aim of this study was to assess the physical activity levels and other risk factors for IHD in PLWH on antiretroviral therapy (ARV). An observational study was conducted from October 2010 to June 2012 at an outpatient clinic in Johannesburg, South Africa. Two hundred and five individuals who were on ARV for 6-12 months were screened. Physical activity was measured with the Yamax SW200 pedometer over a seven day period. Physical activity of the sample was reduced at 7673.2 (±4017.7) steps/ day with women walking less than men 6993.3 (±3462.6) and 10076.3 (±4885.6)respectively. Body mass index was increased to 25.6 (±5.4) kg/m2 with women noted to be overweight [26.6 (±5.5) kg/m2]. Independent predictors of being overweight were systolic blood pressure, waist and hip circumference, CD4 count and daily fruit and vegetable intake. Smoking was less common in the study population with 16.1% of the sample being current smokers and 25.9% former smokers. Individuals’ mean perceived stress levels were 19.9 (±7.8) on the Cohen’s Perceived Stress Scale. The ambulation physical activity level of individuals living with HIV requires modification to assist with reducing risk factors of IHD.

Background Sexually transmitted infections (STIs) continue to rise globally, with >1 million new cases reported daily in 2020. In England, newly diagnosed STIs increased by 23.8% in 2022 compared to 2021. Many infections remain asymptomatic yet contribute to infertility, pregnancy complications, and neonatal morbidity. While routine screening often focuses on Chlamydia trachomatis, broader detection is limited by laboratory turnaround times and restricted test panels. Methods We analysed 6003 home-collected urine and/or swab samples submitted for sexual health screening in the UK. Samples were tested in the laboratory for 10 bacterial and viral pathogens. A total of 5859 urine and 1627 swab samples were processed, with paired samples assessed for diagnostic agreement. Results The most common infections detected in urine were Ureaplasma urealyticum (12.1%), Mycoplasma hominis (8.6%), and Chlamydia trachomatis (2.4%). Swabs showed similar prevalence, with Ureaplasma urealyticum (11.6%) most frequent, followed by Mycoplasma hominis (10.4%) and HSV-2 (4.4%). Paired urine–swab samples demonstrated strong agreement, though swabs improved HSV detection. Conclusions Ureaplasma urealyticum was the most prevalent STI detected, yet only Chlamydia trachomatis is routinely screened in England. Comprehensive laboratory testing of home-collected samples could reduce the hidden burden of STIs, infertility, pregnancy complications, and neonatal infections, while offering confidential and accessible diagnostics.

Background Research and drug development industries have multiphase drug screening procedures, which can be debated. As a result, harmful products may still reach for public health service delivery due to vulnerabilities in the process. Main body A wide range of test compounds have delayed manifestation of undesired effect on the study subject, with the time to undesired effects after acute exposure being weeks and months. Acute toxicology in a preclinical trial also has limited clinical value as its lethal dose is the endpoint for a conclusion, and death sometimes occurs after a scheduled period of acute toxicology. Countless resources are wasted, and numerous new drugs are introduced into the pharmaceutical market with assumed safety analysis every year due to vulnerable multi-procedures in preclinical trials. The principal use of collected data from a preclinical trial is to support regulatory categorization and harmful labelling decisions. However, the data can also be used to derive safe use threshold levels, which may lead to the use of unsafe material. The criteria for classification and labelling also differ among countries, sometimes among authorities within the same country. The fundamental concept of toxicology states that ‘all chemical substances are potential poisons depending on the amount and duration of exposure. However, the toxic property of a test compound cannot be created or eliminated by simply the amount administered to study animals. Conclusion All xenobiotics are poisons at any amount with different severity that can be calculated using biological parameters.

With more than 150,000 affected infants annually, Nigeria bears the largest burden worldwide of sickle cell disease (SCD), making it a significant public health concern. The management of SCD in Nigeria is challenging, despite advancements in medical research and increased knowledge. This review examines the numerous issues surrounding SCD in the nation, including the financial burden on affected families, the lack of specialized care facilities, the absence of newborn screening programs, the sociocultural stigmatization of SCD, and restricted access to high-quality healthcare. Additionally, inadequate public health education and a lack of coordinated national policies result in delayed diagnosis and suboptimal treatment outcomes. We also highlighted recent efforts and recommendations aimed at improving early detection, comprehensive care, and community support. Addressing these challenges through expanded health education and enhanced healthcare infrastructure is essential to reducing morbidity and mortality associated with SCD in Nigeria.

Background Attention-deficit/hyperactivity disorder (ADHD) in adulthood is increasingly recognized not only as a psychiatric condition but also as a trait with behavioral and occupational implications—particularly in high-stakes, fast-paced financial environments. Traits such as impulsivity, sensation seeking, and altered reward sensitivity may influence decision-making among individuals engaged in stock trading or high-risk investment professions. Objective This systematic review and meta-analytic synthesis aims to investigate the relationship between ADHD, impulsivity, gender differences, and financial risk behavior, with a particular focus on decision-making outcomes in real or simulated trading contexts. Methods Seventeen peer-reviewed studies published between 2008 and 2025 were included. Studies employed behavioral experiments, fMRI paradigms, neurochemical analysis (e.g., glutamate levels), and ecological financial assessments to examine impulsive traits and investment behaviors among adults with and without ADHD. Both clinical samples and occupational cohorts (e.g., brokers, retail investors) were analyzed. The analysis followed PRISMA 2020 guidelines. Results ADHD symptoms—particularly impulsivity and reward hypersensitivity—were associated with increased delay discounting, higher risk-taking, and diminished cognitive control in financial tasks. Neuroimaging data revealed hypoactivation in prefrontal control regions and hyperactivation in reward-related circuits (e.g., ventral striatum). Gender-stratified analyses showed that males with ADHD displayed stronger preference for immediate rewards, higher portfolio turnover, and greater volatility. Preliminary evidence also suggests an overrepresentation of ADHD traits in high-frequency trading roles. Conclusion ADHD-related impulsivity significantly modulates financial risk behavior, particularly in high-stakes and fast-paced contexts such as trading. A convergence of behavioral, neurobiological, and ecological findings suggests that males with ADHD are disproportionately prone to rapid, high-risk financial decisions, whereas females may demonstrate greater regulatory control. These insights underscore the need for gender-sensitive interventions, occupational screening, and tailored psychoeducation. As financial environments become increasingly automated and fast-paced, understanding the neurocognitive vulnerabilities of individuals with ADHD may not only protect personal outcomes but also enhance systemic financial stability.

Background/Aim Obstructive Sleep Apnea (OSA) is a prevalent disorder characterized by recurrent respiratory disturbances during sleep. Patients with Type 2 Diabetes Mellitus (T2DM) and obesity exhibit a substantial susceptibility to OSA (23%–86%). People with OSA have a high risk of several comorbidities like insulin resistance, cardiovascular disease, depressed mood and hypertension. Thus, the objective was to comprehensively evaluate the risk of OSA among T2DM patients in India. Materials and Methods A cross-sectional survey was conducted across four cities in India involving 2,000 T2DM patients. The survey gathered data on patient demographics, clinical endpoints, and estimated the risk of OSA using an app which included the STOP BANG questionnaire. Multivariate logistic regression analysis was used to evaluate the association between OSA risk and key variables such as age, gender, BMI, and HbA1c. Result Overall, 63.9% of T2DM patients were identified as high risk and 27.3% were at intermediate risk for OSA development. Results of the multivariate logistic regression demonstrated that patients with high BMI ≥35 had significantly greater odds (OR: 5.70; p<0.00) of developing OSA; males had 2.75 times higher odds (p<0.00) and patients with HbA1c value >8% had higher odds (OR: 1.22; p<0.00) of developing OSA. Conclusion OSA risk and prevalence are significantly higher in T2DM patients than in the general population with a notable escalation in patients who are overweight/obese, older, and have prolonged diabetes duration. Early screening using digitalization with a highly sensitive, cost-efficient, and valid tool like STOP-BANG followed by appropriate intervention for OSA can not only reduce the eventual economic burden but can improve patient outcomes.

Background Beta-Sitosterol (SIT) is an active TCM compound employed to treat diabetic retinopathy (DR). A network pharmacology approach to understanding the active ingredients and the therapeutic mechanisms underlying DR has not been pursued. Methods The potential targets for DM were identified according to the MedGene, Gendome, HGNC, OMIM, GeneCards, PheGenI, GEO, and STRING database. The herb and components were predicted and screened by network pharmacology through oral bioavailability and drug-likeness filtration using the Traditional Chinese Medicine Systems Pharmacology Analysis Platform database. A network pharmacology prediction and network analysis were used to predict the active potential targets and pathways of SIT application to DR. Results We found the Top 15 DR-related genes by screening in 9 databases. 26 kinds of TCM and nearly 300 kinds of active ingredients. SIT exists in 10 kinds of DR-treat TCM. The comprehensive network pharmacology approach was successful in identifying 23 kinds of core genes for SIT treating DR. ERBB3 and IGF2-related PI3K-Akt signaling pathway or EDN3, IGF2 and SPP1-related receptor ligand activity pathway might be the main pharmacological targets, and pathways in DR. We speculated that SIT was effective for the treatment of DR. Conclusion Based on the network pharmacology, we predicted the potential targets of SIT in treating DR and helped to illustrate the mechanism of action. Our study identifies key genes and pathways associated with the prognosis and pathogenesis of DR from new insights.

Objectives This study examined the frequency and dynamics of syphilis in the United Arab Emirates (UAE) between 2018 and 2022. Recognizing the significance of understanding syphilis trends, this study intends to conduct further research on sexually transmitted diseases in the context of the UAE. Methods This was a retrospective cross-sectional study. This study focused on patients who underwent syphilis screening between January 2018 and December 2022. Cases were classified as conclusive only if they passed the first screening and subsequent confirmatory tests. Results The findings demonstrate that Syphilis frequency varied throughout the UAE during the study period. Demographic trends and sex variations were discovered, providing insight into how syphilis patterns change. Additionally, this study identified a broad spectrum of clinical manifestations, confirming the complexity of the disease. It was also noted that males had a higher frequency of syphilis than females. Conclusion Understanding the complexity of the frequency of syphilis is critical for developing effective public health interventions. Variations in frequency, demographic trends, sex disparities, and clinical manifestations indicate the need for personalized preventive and control measures. This study provides important information that may be utilized to motivate focused initiatives to address the difficulties associated with syphilis in the UAE, thus enhancing overall public health.

Camels are a significant source of income for nomadic populations in many developing countries, including Ethiopia. Camels are well adapted to dry and semi-dry regions, providing income, food security, and transportation. However, camel production and productivity are constrained by infectious diseases, such as brucellosis, which is a highly infectious bacterial disease that affects camels and humans worldwide. Brucellosis causes significant economic losses due to abortion, low herd fertility, and decreased milk production. In Ethiopia, the prevalence of camel brucellosis varies depending on factors related to the host, agent, climate, and management system, with a reported prevalence ranging from 0.5% to 11.9%. Accurate diagnosis of camel Brucellosis is essential for herd-based screening of animals. Although culturing the pathogen is the preferred method for diagnosis, serological tests such as Rose-Bengal plate test (RBPT), Enzyme-linked immunosorbent assay (ELISA), and Complement fixation test (CFT) and polymerase chain reaction (PCR) assays have been developed. Implementing effective diagnosis and surveillance systems to control the spread of brucellosis in animals and humans is very important, on top of awareness campaigns, vaccination programs, and suitable laboratory establishment recommended. Continued research is essential to maintain the health and productivity of camel populations, particularly in pastoral areas where camels play a significant role in the livelihood of communities. Therefore, the present paper views the seropositive prevalence and potential risk factors associated with camel brucellosis in Ethiopia.

Groove pancreatitis (GP) is a rare type of segmental chronic pancreatitis that affects the anatomical area between the pancreatic head, the duodenum, and the common bile duct, referred to as the groove area. Most patients with groove pancreatitis are males aged 40–50 years with a history of alcohol abuse. The prevalence of this condition was not determined due to rarity of cases.The clinical symptoms commonly reported were weight loss, upper abdominal pain, postprandial vomiting, and nausea due to duodenal stenosis. It is considered difficult clinically and radiographically to distinguish this form of chronic pancreatitis from other differential diagnoses of inflammatory conditions or malignancies affecting the pancreas or adjacent structures to that groove area. We report a challenging case of GP in an asymptomatic female patient during routine gastric ulcer screening. Our objective is to draw attention to this rare and atypical type of chronic pancreatitis and the importance for early detection on screening EGDs prior to its symptomatic sequelae and complications.

Background Immunological abnormalities are currently under scrutiny to potentially unravel the etiology of frustrating cases of unexplained female infertility (UFI). Objectives To explore the prevalence of immunological abnormalities in the levels of total immunoglobulins and complements in the cases of UFI. Methods Females with a history of UFI were included in this cross sectional study. They were consulted at the clinical immunology clinic at the King Abdulaziz University Hospital (KAUH). Their demographics, clinical features, total immunoglobulins and complements tests results were collected and analyzed for any relationship. Results One hundred and twenty-one cases of UFI with an average age of 34 ± 5.6 (range from 23 to 49 years old) were studied. Secondary infertility was predominant in 99 cases (81.8%). An overall prevalence of at least one abnormal level of total immunoglobulins or complements was found in 65 cases (55.1%). The predominant immunological abnormalities were elevated levels of immunoglobulins (hypergammaglobulinemia) in 51 cases (43.2%), high IgG in 26 cases (22%), high IgA in 14 cases (11.9%), and high IgM in 11 cases (9.3%). This was followed by elevated levels of complements (hypercomplementemia) in C4 in nine cases (8.5%). A significant association was found between high C4 group and some parameters of infertility, including primary infertility (p = 0.005), no pregnancy (p = 0.001), no abortion (p = 0.047), in comparison to normal C4 group. Moreover, a statistically significant association was found between high IgA group and abortion in comparison to normal IgA group (p = 0.054). Conclusion At least one abnormal level of total immunoglobulins or complements was detected in more than half of the UFI cases. The commonest abnormalities were hypergammaglobulinemia (IgG, IgM, IgA) and hypercomplementenemia (C4), which showed a potential association with some infertility parameters. These findings may encourage the screening of general immunological tests to explore promising new immunopathology in UFI.

Syphilis is caused by the bacterium Treponema pallidum and is transmitted from human to human through sexual contact. Congenital syphilis (CS) occurs when the mother transmits the infection to the fetus. Clinical manifestations of CS include anemia, hepatosplenomegaly, blindness, deafness, meningitis, and deformities in bone structure. The number of cases of CS have increased over the past decade in the United States according to the CDC. A study was conducted correlating the number of Medicaid enrollees in 2020, the number of uninsured persons in 2020, and the number of cases of COVID-19 in 2020 to cases of CS in the United States in 2021. A Spearman rank correlation analysis was done using SPSS. Results were statistically significant for all three pairs of variables with positive correlations; Medicaid enrollment and CS cases (r = 0.735, P<.05), uninsured persons with CS cases (r = 0.713, P<.05), COVID-19 cases and CS cases (r = 0.689, P<.05). Reasons for the increase in CS cases are multifactorial, including variations in state laws regarding syphilis screening in the prenatal period, differences in provider processes for persons on Medicaid, persons uninsured, and restrictions to accessing healthcare providers during the COVID-19 pandemic. Future studies should include questionnaires and interviews with women on their experiences during prenatal visits in regards to syphilis screening, particularly women covered by Medicaid, and surveys completed by healthcare providers to gain insight and to identify factors that affect a woman not being tested for syphilis during her pregnancy.

The major a biotic stresses affecting chickpea production are high and low temperature, drought and salinity. Heat stress is a major a biotic stress factor, constraining chickpea production worldwide. This study was conducted to identifying chickpea genotypes combining heat tolerance and high yield potential and to study correlation among the heat tolerance indices. The genotypes were tested under different field-growing conditions, normal sown (non – heat stress) and late sown (heat stress) at two locations, Merowe and Gezira during winter season 2018/2019. The trials were laid out in alpha lattice design with three replications. Eight heat tolerance indices, which were most frequently used in plant breeding including, geometric mean productivity (GMP), yield index (YI), mean productivity (MP), stress susceptibility index (SSI), stress tolerance index (STI), tolerance index (TOL), sensitivity heat index (SHI) and relative heat index (RHI) were calculated based on seed yield under heat stress (Ys) and non – heat stress (Yp) conditions. Under both environments, the results from combined analysis of variance showed that there were highly significant differences among the genotypes for all traits studies. There were highly significant differences observed among the tested chickpea genotypes response to heat stress. Seed yield in stress (Ys) condition was positive and highly significant correlated with geometric mean productivity, yield index, stress tolerance index and relative heat index. The Ys was negative and highly significant correlated with stress susceptibility index and sensitivity heat index. Seed yield in non-stress (Yp) condition was positive and significant correlated with geometric mean productivity, yield index, stress tolerance index and tolerance index. The results of this research showed that the six indices, GMP, YI, SSI, STI, SHI and RHI can be used as optimal indicators for screening heat tolerant chickpea genotypes. Nine genotypes including four released improved varieties (Shiekh Mohamed, Wad Hamid, Salwa and Hwata) and five genotypes (no. 11, 4, 26, 30 and 34) are most stable chickpea genotypes for heat tolerance and can be further used in breeding program. These genotypes can be used in the chickpea national breeding program to develop varieties with improved heat tolerance in Sudan. Genotype no. 11 (FLIP 08-59 C) was release by Sudan national variety release committee for commercial production under the name Elbarkal in September 2022 to will be grown in Gezira, River Nile and Northern States of Sudan.

Objective To describe the epidemiological, clinical and arterial Doppler ultrasound aspects of abdominal aortic aneurysm (AAA). Material and Methods This is a prospective study with descriptive and analytical aims carried out from January 2019 to March 2022 (3 years) at the cardiovascular exploration center (CEC) "Saint-Esprit" of the association of the people's doctors for the research on cardiovascular diseases (AMP-MCV), at the clinic "Le Printemps" and at the University Hospital of Kara. All patients who underwent arterial Doppler ultrasound of the lower limbs for any reason in these centers during the study period were included. Ultrasound scans were performed or confirmed by a physician with a diploma specializing in vascular Doppler ultrasound. Results We retained 32 Doppler ultrasound scans out of 739 performed for AAA with a frequency of 4.38%. The mean age was 73.5± 9.07 years. The sex ratio M/F was 1.4. The cardiovascular medical history (84.38%) found was: hypertension (33.33%), diabetes (18.52%), dyslipidemia (33.33%) and a combination of diabetes and hypertension (14.81%). The circumstances of discovery were: downstream MI ischemia (72%), incidental finding on abdominal ultrasound (15.63%) and De bakey sign (6.25%). The location of the aneurysms was subrenal (84.4%), suprarenal (9.4%) and both (6.2%). AAAs were fusiform (71.9%) and saccular (28.1%). The size of the aneurysms was greater than 5 cm in 78.17% of patients. High blood pressure increases the probability of the occurrence of subrenal AAA while dyslipidemia increases the occurrence of fusiform AAA. Diabetes increases the probability of occurrence of AAA larger than 7cm. AAAs were thrombosed in 75% of patients. There were extensions of the aneurysms to the iliac arteries in 70.59%. Downstream embolic complications represented 46.88%, in the form of occlusions and tight stenoses. Spontaneous mortality was 81.24%. Conclusion Arterial Doppler ultrasonography is a very important tool in the screening, positive and lesion diagnosis of AAA. The risk factors for AAA are: age over 60 years, male gender, hypertension, diabetes and dyslipidemia. Early detection remains essential, because the spontaneous prognosis is poor.

The process of creating new pharmaceuticals is incredibly costly and time-consuming, and it dates back millions of years to the time when only herbal remedies were used. Furthermore, the solvation energies of the ligand and receptor site are crucial to this process because partial to complete dedication must take place before binding. The full form of CADD is computer-added drug design. To enhance the design and discovery of, CADD stands for computational methodologies and resources. Smaller numbers of chemicals are chosen from extensive compound libraries for experimental testing. There is less screening. Pharmacogenomics’ main benefit is the ability to develop medication based on the genomiy organization of each individual. The immense potential of enzymes as therapeutic targets is exemplified by under R's leadership, Merck's strategy.

The greater wax moth considered one of the most worldwide-spread pests of the bee wax. This Study was designed to investigate the insecticidal activity of Carumcarvi, Eculaptus camaldulensis and Nigella sativa against 3rd larval instar of G.mellonellathrough laboratory screening. Five concentrations (5%, 7.5%, 10%, 12.5% and 15%) of each plant extract were used in this experiment. Mortality (%) was recorded after 24, 48, 72 and 96 hrs post treatment. The results showed C. carvi, E. camaldulensis and N.sativahave insecticidal activity against 3rd_ instar larvae of G. mellonella. The highest concentration (15%) caused 90% ,86.7% and 80% larval mortality after 96 hrs for C. carvi,E. camaldulensis and N.sativarespectively. The statistical analysis revealed that there is a significant difference (p< .001) between all treatments and control. The results also clearly demonstrate that the C. carvi are significantly more toxic than E. camaldulensis and N. sativa, whereas the LC50 values were 5.4% forC. carvi,6.0% for E. camaldulensis and 6.2% for N. sativa.

Tay-Sachs disease (TSD) is a rare neurodegenerative disorder caused by mutations in the HEXA gene, which encodes the ɑ subunit of the enzyme β-hexosaminidase A. Lacking this key enzyme in GM2 ganglioside catabolism, individuals who are homozygous for HEXA mutations suffer from abnormal accumulation of GM2 ganglioside in brain and nerve cells, ultimately resulting in the progressive deterioration of the central nervous system. TSD is one of three disorders characterized by β-hexosaminidase deficiency; Sandhoff disease (SD) and the AB variant arise by mutations in the HEXB and GM2A genes respectively, which disrupt other points of GM2 ganglioside degradation. Characterized by developmental delay and stagnation, muscular weakness, coordination deficits, seizures, and eventual hearing and vision loss, these three disorders are clinically indistinguishable and occur in three forms defined by age of onset. While there is a much higher incidence of TSD in the Ashkenazi Jewish population, community carrier screening and counseling initiatives have reduced disease prevalence to about the equivalent of non-Jewish populations; however, such efforts have raised ethical concerns in the Jewish community that are increasingly relevant in light of scientific and medical advancements. Currently, treatments for TSD and its related disorders focus on symptom management, with gene therapies and the application of modified CRISPR-Cas-9 technology being explored.

Background The COVID-19 pandemic has had significant impact on healthcare worldwide. Surgeons are at increased occupational risk of contracting COVID-19. The impact of the disease on surgical practice will continue to evolve. We assessed the impact of the disease on surgical practice and training in Nigeria. Method Survey questionnaire was designed, transcribed to Google form and electronically circulated online to surgeons practicing in Nigeria. Surgeons from various subspecialties from the six regions in Nigeria were included. Survey questions pertaining to pre-COVID-19 era surgical practices, impact on current practice and changes occurring in health facilities during this COVID-19 pandemic. Responses were collated and analyzed statistically. Results One hundred and nine (109) surgeons completed the survey, of which 2.8% were women. Majority (68.8%) of the respondents are in the consultant cadre, majority (86.2%) are working in public hospital, 88.1% running their SOPD, 81.7% have isolation wards in their centers, 66.1% have dedicated team for COVID-19 management. Only 48.6% of the frontline health workers have access to personal protective equipment (PPE), and 33.9% had formal training on the use of PPE. Only 11.0% were satisfied with level of preparation of the management. Elective cases were done only in 45% of respondents. 103(94.4 %) confirmed that the numbers of elective cases are less than pre Covid-19 period. Emergency cases were carried out by 93.6% of respondents. Only 1.8% of respondents carried out screening tests for their patients before embarking on emergency surgery. Conclusion COVID-19 has led to reduction in surgical outpatients, significant reduction in elective surgeries in Nigeria. Adequate PPE needs to be provided, there should be guidelines for safety for future. There should be adequate preparation should there be any pandemic in the near future.

Background The nutritional situation in prisons of developing countries and the health status of inmates remain a major human rights concern. The objective of the study was to assess the nutritional status of inmates jailed in a prison of the Democratic Republic of Congo (DRC). Methods This cross-sectional study was conducted over a 4-month period in the Central Prison of Mbuji-Mayi, DRC. Three hundred inmates were selected according to the Malnutrition Universal Screening Tool (MUST). Severe malnutrition was defined according to Buzby index and Nutritional Risk Index (NRI). Data were analyzed by Stata™ (version12.0). Results The inmates were aged between 18 and 70 years and primarily males (88.7%). Of them, 24% were suffering from severe malnutrition and 62% of moderate malnutrition as based on the NRI. At the time of study, 88% of inmates were incarcerated for more than 6 months. Multivariate logistic regression analysis showed that factors independently associated with severe malnutrition were incarceration of more than 6 months (OR=5.1; 95% CI (1.5-17.4)), origin of food (prison vs. family or NGO) (OR=4.7; 95% CI (1.6-13.8)) presence of tuberculosis, human immunodeficiency virus and/or intestinal infections (OR=2.6; 95% CI (1.4-4.7)). Conclusions The nutritional situation in the Central Prison of Mbuji-Mayi is precarious. There is urgent need to supply enough nutrient-rich food to improve health of inmates.

Helicoverpaarmigera is one of the most destructive pests of field crops worldwide. The Study was designed to investigate through laboratory screening the insecticidal activity of Ricinus communis, Cassia occidentalis and Bacillus thuringiensis var. Kurstaki (Btk) and their combinations against 2nd larval instar of H. armigera. Five concentrations (4%, 6%, 8%, 10% and 12%) of each plant extract and (0.62, 1.25, 2.5, 5, and 10 mg/ml) of Bt were used in this experiment. Mortality (%) was recorded after 24,48,72 and 96 hrs post treatment. The results showed that R. communis, C. occidentalis and Btkhave insecticidal activity against 2nd instar larvae of H. armigera. The highest concentration (12%) caused 80% and 70% larval mortality after 96 hrs for R. communis and C. occidental respectively. The statistical analysis revealed that there is a significant differences between all treatments and control. Additionally, all combinations (plant/plant or plant/Bt) increased the mortality %. The results also clearly demonstrate that the R. communis are significantly more toxic than C. occidental where the LC50 values were 6.4 % for R. communis and 8.1% for C. occidental. On the other hand LC50 value for Bt was 0.41 mg/ml. The binary mixture of R. communis and C. occidental have a potentiation effect after 48 hrs. Regarding the mixture of Bt and plant extracts the results revealed that R. communis and Bt mixture induced a potentiation effect whereas C. occidental and Bt mixture induced a an additive effects.

Background Ethiopia confirmed its 1st case of COVID-19 on Friday 13th February 2020. The burden increased dramatically by August/2020. The conditions that led to this rise were not reviewed. Objective To exploreCOVID-19 related phenomena in Ethiopia during 2019-2020. Materials and Methods Review of journals, books, and letters to editors, e-sources, news, personal experiences, observations, and communications. Results The zoonotic source of SARS- CoV-2 (Severe Acute Respiratory Distress Syndrome- Coronavirus-2) is not confirmed. The precedent events; and exact mechanism of COVID-19 is not clear. Dynamic models were required on the time line of dynamics of COVID-19; dynamics of infectiousness of COVID-19, and mechanism of transmission of COVID-19. Incubatory carriers might have been missed. Screening based on temperature had been problematic. The time spent in the development of diagnostic test for COVID-19 might have contributed to the early spread. Uninterrupted flights to China during the epidemic by Ethiopian Airlines as well as uninterrupted domestic flights; IDP (Internally Displaced People); and others put Ethiopia (and other countries) at great risk. Demographic adjustment may not be applicable for Ethiopia due to lack of census which had to be conducted every 10 year, was conducted only in 2007. This adds to the problem of error projection. The impact of HIV (Human Immuno-Deficiency Virus Disease) and war in Ethiopia before 2000 might have had affected people who would be now old age and who would be at the most risk of death. This made the impact of COVID-19 to appear low as revealed by the lower number of COVID-related deaths in Ethiopia. There were also hesitations inconsistencies in case definitions; implementations of quarantine; and burial regulations. Conclusion Even though uninhibited foreign flight to China as well as domestic flights; inconsistencies in the implementation of regulations pertaining to COVID-19 have contributed to COVID- 19 emergence in Ethiopia, the absence of census; the demographic impact of HIV and war before 2000 might have made the impact of COVID-19 to appear low as revealed by the lower number of COVID-related deaths in Ethiopia. Recommendation Accurate and current evaluation of the impact of COVID-19 in Ethiopia may require the absence of census; demographic consequences of HIV; and war before 2000 into consideration.

The paper describes the development of a long-lasting product for Intra-domicile residual spray (IRS) and shows it is possible to obtain a residual effect of nearly 2 years. However, to obtain that the methods currently recommended by WHO for laboratory evaluation had to be modified and approached methods closer to the semi-field and field evaluations as applied in later phases of WHO procedures. Surfaces with high pH resulted in short residual effect unless the formulations were mixed with a silicone coating. Screening in huts constructed for the purpose was realised by dividing the wall surfaces in 25 test plots of 0.5 m² where formulations were applied randomly with more repeats the closer to the final formulation. Mud and concrete surface were more challenging than wood surface and stones and these could be dropped for screening. Wall surfaces heated by sun were repellent to non-blood fed mosquitoes, and the test in huts were limited to the mornings. However, blood fed mosquitoes were not repelled. Cone tests on mud-walls are complicated by the uneven structure of the surface and a better way of attaching cones to avoid mortality errors was developed. Formulations that can be applied and last for two mosquito seasons produce big cost savings for IRS programs, since program costs are mostly application costs.

In contributing to the initiative to address the COVID-19 pandemic and in order to enhance the knowledge on driving forces shaping the evolution of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) (isolated from Tunisian patients), a comparison in relation to other coronaviruses infecting humans (SARS-CoV-1, MERS-CoV, HCoV/229E, HCoV/NL63, HCoV/OC43, and HCoV/HKU1) as well as animals (SARS-CoVs in tiger, bats, civet, pangolin, bovine, and MERS-CoV in dromedary/camel), was conducted. In-depth analysis was carried out involving 115 sequences of spike glycoprotein-coding gene extracted from the international databases. Phylogeny inference allowed the reconstruction of a bifurcating tree where four distinct groups were delineated and at the same time, three animal accessions (SARS-CoV-2/tiger, MERS-CoV/camel, and SARS-CoV/bovine) shifted from the animal group and integrated the human coronaviruses clades. Nonetheless, in the presence of reticulate events such as recombination, networks described better the phylogenetic relationships rather than the classic dendrogram. Thus, networks were produced and identified four clusters containing sharply demarcated subgroups (eight subdivisions). Except networked phylogenies of SARS-CoV-1, SARS-CoV-2, and HCoV/HKU1, all the others showed edges and boxes illustrating the occurrence of incompatibilities related to the sequences of spike glycoprotein-coding gene. Thereby and consolidating this result, three methods (RDP package, GARD, and RECCO) were used to detect breakpoints in aligned sequences. Except the clades SARS-CoV-1 and SARS-CoV-2, all the remaining phylogenetic subdivisions were subject to recombination. Furthermore, the screening of selection pressure in all studied sequences by various statistics-based models of the HyPhy package, showed that, similarly, the lineages belonging to the clades SARS-CoV-1 and SARS-CoV-2 were not under selection. In contrast, all members of the remaining clades underwent, to different extents, adaptive selection as well as purifying selection.

Background Falls injuries continue to contribute to numerous premature deaths as well as high disability levels, and excess morbidity rates among older adults, worldwide. But can vitamin D account for excess falls injuries among older adults? This review specifically focuses on what is known about vitamin D in the context of postural stability or balance control, both fairly consistent independent predictors of falls among older adults. Methods and Procedures Drawn largely from a review of current relevant English language peer reviewed research publications published over the last 10 years detailing the relationship between vitamin D levels and balance control among the elderly, as this relates to falls injuries, evidence for any emerging consensus on this controversial topic was sought. Used to conduct the search were various key word combinations including: falls injuries and older adults, vitamin D or vitamin D deficiency and balance or postural control. The database used predominantly to provide input into this largely descriptive assessment and narrative overview was PUBMED. Results The prevailing data show falls injuries currently constitute a widespread costly major impediment to successful aging and longevity for many older adults, despite numerous efforts to prevent this disabling set of events over the past two to three decades. However, no consistent association appears to exist between the variables of vitamin D, falls, and balance attributes in the older population-despite years of research, regardless of study approach, and a strong rationale for hypothesizing a clinically meaningful relationahip. Conclusion It is not possible to arrive at any universal recommendation concerning the value of vitamin D supplementation as regards its possible influence on balance capacity among older adults in the realm of falls prevention efforts, as has been frequently proposed. However, until more definitive research is conducted, there still appears sufficient justification for considering the screening of vulnerable aging adults for serum vitamin D levels, along with balance impairments, and intervening as required in the case of deficits in either or both of these possible falls determinants.

Africa Region has the highest burden of malaria with an estimated of 3.5 million more malaria cases in 2017 compared 212 million cases in reported in 2016. Data collected from 2015 to 2017, shown no global progress in reducing malaria cases. In Mainland Tanzania, malaria control interventions have significantly led to the reduction in malaria prevalence from 18.1% in 2008 to 7.3% in 2017. Despite of these achievements, malaria burden is still highly heterogonous with some regions including urban peripheral areas of Dar es Salaam, presenting persistent malaria transmission ranging from 2 to 57%. Material and Methods A cross- sectional population based survey was carried out in Ilala Municipality in Dar es Salaam; data was collected from 2nd to 31 April, 2019. Multistage cluster sampling was used to select the households where individual member were conveniently selected to participate in the study. Structured questionnaire were administered by the trained researcher assistants to assess individual risk factors for malaria. Rapid Malaria diagnostic test (mRDT) was used to identify individual exposed to malaria infection. Measure of association used was prevalence odds ratio (POR). Multivariate regression model used to determine prevalence odds ratio, variable with p- value < 0.05 were considered as independent risk factor for persistent malaria transmission. Results A total of 830 participants were recruited in the study, mean age was 24yrs ±20.4SD. Majority 489 (58.9%) were female, 459 (55.3%) were >18 yrs old, primary or no education were 687 (82.8%), farmer or unemployed were 639 (77%). Msongola ward contributed 406 (48.9%). Overall malaria prevalence in the study areas was (4.5%). Nets ownership was 141 (16.9%), usage was 121 (85.8%).Low proportion of net ownerships (POR: 7.67, 95% CI: 4.23, 24.6), residing in the households surrounded by mosquito breeding sites POR: 20.07, 95% CI: 7.03, 57.29) and residing in houses with unscreened windows (POR: 1.21, 95% CI: 1.26, 3.40) were independently associated with malaria infection. Conclusion Low nets ownership, residing in the households surrounded by mosquito breeding sites and in households with unscreened windows was independent factors associated with risk of malaria in the areas. Promotion of ITNs coverage, application of biolarvicides through community engagement and house screening was recommended to reduce the risk of malaria infection in the areas.

Background Anemia of chronic disease is anemia found in certain chronic disease states, is typically marked by the disturbance of iron homeostasis or hypoferremia. Chronic renal failure is currently known as Chronic Kidney Disease (CKD) or Chronic Renal Insufficiency (CRI) implies long-standing, progressive and irreversible renal parenchyma disease resulting in diminished renal function up to 40 to 60%. Often, chronic kidney disease is diagnosed as a result of screening of people known to be at risk of kidney problems, such as those with high blood pressure or diabetes and those with a blood relative with chronic kidney disease. This disease may also be identified when it leads to one of its recognized complications such as cardiovascular disease, anemia, or pericarditis. Methods Sysmex kx21 used to CBC and the Cobase411 used to iron profile. Enzyme-Linked immunoassay (ELISA) was used to determine the level of serum hepcidin. Sample preparation and PCR detection of HAMP DNA Polymorphisms: Restriction digestion of PCR products was done using Fast Digest. (Figure 1). Results Serum hepcidin levels higher in patients with anemia of chronic kidney disease compared with healthy controls mean. The polymorphisms of the hepcidin gene promoter in Sudanese patients with ACKD showed that the hepcidin HAMP AA genotype 70, AG 23, and GG 7 in 100 patients dialysis-dependent and AA 83, AG 17 and GG 0, and the allele A are more frequent in patients affected by ACKD. Significant statistical association observed between the hepcidin level and end-stage kidney disease. Conclusion This study evaluates for the first time the association between anemia of chronic kidney disease and hepcidin genes promoter polymorphisms and show that the hepcidin HAMP AA genotype and the allele A are more frequent in patients affected by ACKD, further investigation is needed, our data support the hypothesis and hepcidin HAMP are important in the pathophysiology of ACKD.

Introduction The anti-HCV RIBA test verifies the presence of anti-HCV serum antibodies detected by the Elisa test. In Côte d'Ivoire, screening for hepatitis C is done exclusively by enzyme immunoassays. In order to reduce the number of HCV positive blood donor exclusions on ELISA, we conducted this study which aimed to demonstrate the value of the RIBA test in confirming diagnosis of viral hepatitis C to blood donors. Methods Our study, which took place from 02 to 23 February 2008 in the laboratory of Abidjan NBTC, focused on 200 sera of blood donors anti-HCV positive (Elisa test) selected according to the ratio. The DECISCAN HCV PLUS confirmation test of BIORAD was used. Results Among the 200 HCV samples positive by EIA, 49% (98/200) were confirmed positive. RIBA gave an indeterminate result in 40% of cases (80/200); and negative in 11% of cases (22/200) corresponding to false ELISA devices. In RIBA 96 samples had a low ELISA ratio of which 21% (20/96) were RIBA negative, and 79% (76/96) were indeterminate. RIBA positive samples (98/200) had a high ratio in 82% of cases (80/98). The presence of NS3 (C33) and NS4 (C100) was noted in 100% of cases (98/98, C2 in 37% (36/98) of cases and C1 in 18% of cases (18/98). RIBA indeterminate noted the presence of NS3 in 98% of cases (78/80) and NS4 in 30% of cases (24/80). Proteins C1, C2 and NS4 are essential for the diagnosis of confirmation of viral hepatitis C by RIBA. Conclusion These results attest to the lower specificity of enzyme immunoassays (ELISAs); hence the benefit of using RIBA confirmatory tests. A significant number of donors are excluded from blood donation in Côte d'Ivoire on the basis of false positive results obtained by the ELISA technique.

The agronomic management of symbiotic (S) inoculations, by means of bio-fertilizers (BF), is aimed at inducing modifications of the plant rhizosphere and thereafter of the phenotype and yield of the crop. It is here shown that the yield response of maize to a symbiotic treatment may be correlated to six easy-to-calculate indicator variables on the basis of the raw foliar pH, NIR-Spectroscopy of leaves, and the NIRS of hay litter-bags from soils. It has been confirmed, in a set of thirteen pairwise comparisons of Symbiotic (S) soil inoculated by BF vs. Control (non-inoculated soil; C), that the inoculation on average acidified the leaves by -3.7% pH units (P<0.0001). The responses in yield ranged from +25.2% to -9.2% (av.ge +3.5%; P = 0.03), but with average null responses in two centers and a significant response (+11%) in a third center. NIR-Tomoscopy scans (No. 574) were also performed on the leaves, and in addition, hay-litter-bags that had previously been buried in fields were dug up after two months, and 431 NIR- scans were acquired. The effect-size on the yield was expressed as the logarithm of the response ratio, i.e. the mean of the inoculated Symbiotic treatment divided by the mean of the non-inoculated Control for each pairwise comparison. A multiple regression model was developed to predict the symbiotic response to the treatment using six independent variables, including the squared litter-bag fingerprints, and an R2adj. level of 0.78 (P=0.01) was reached, with a standard error of ±4%. Validation in one external maize field, with a positive response to bio-fertilizers, demonstrates the juxtaposition of the estimated and accomplished yield. In a second experiment, with 40 pairwise comparisons, the two tested maize varieties did not respond to five types of bio-fertilizer, and the negative results were predicted at 84% (P 0.0012). The soil biota is a key factor for the application of appropriate microbial inoculants in the field, but the genotype/genotype interactions between the microbial strain (s) and the crop cultivar (s) require prior screening to obtain the desired results.

The purpose of this study is to evaluate the impact of organic pollution of EL-Mahmodia canal on the fish (Oreochromis niloticus)muscles tissues collected from two sites at EL-Mahmodia canal in summer and winter 2017. EL-Mahmodia canal is exposed to excessive of effluents which impact fish. The present results showed high concentrations of organic pollutants, particularly in winter. Organic pollutants were analyzed using the gas-chromatography-mass spectrometry (GC-MS). A variety of environmental screening studies concerning varieties of water pollutants in Egypt, the target of the present study was to scan the organic pollutants of El-Mahmodia stream at El-Beheira Governorate, Egypt within the muscles of Tilapia fish. Within the present study, it was found that; the analysis of fish muscles in summer season showed a high level of organic pollutants. The organic pollutants that are reported in the muscle of fish in the polluted site were reported as; Dimethomorph-(E), Hexestrol, Diisobutyl phthalate, Diamyl phthalate, Di-n-propyl phthalate, Chlorpyrifos, Phorate sulfoxide, Exaltolide (15-Pentadecanolide), Chlorfenapyr, Pyridate, Ethofumesate, Bis (2-ethylhexyl)phthalate, Dicyclohexyl phthalate, Di-n-octyl phthalate, Tricresylphosphate, meta-, XMC (3, 4-Dimethylphenyl N-methyl, XMC (3,5-Dimethylphenyl N-methyl, Hexestrol, Thymol, Kinoprene, Diisobutyl phthalate, Diisobutyl phthalate, Di-n-hexyl phthalate, Di-n-hexyl phthalate, Carbofuran-3-keto, Tefluthrin, cis-, Carbofuran-7-phenol, Carbofuran, Dicyclohexyl phthalate, Di-n-propyl phthalate, Di-n-propyl phthalate, Bis(2-ethylhexyl)phthalate, Ethofumesate, Hexestrol, Kinoprene, Di-n-hexyl phthalate, Exaltolide (15-Pentadecanolide), Spiroxamine metabolite (4-tert-b), Chlorfenapyr, Tricresylphosphate, para, Tricresylphosphate, meta-, Tricresylphosphate, ortho-, XMC (3, 5-Dimethylphenyl N-methyl, XMC (3,4-Dimethylphenyl N-methyl, Fluroxypyr-1-methylheptyl ester, Cashmeran, Propargite metabolite (Cyclohexa), and Quinoclamine. The present results showed that Diisobutyl phthalate, Bis(2-ethylhexyl)phthalate, Pyridate and Ethofumesate were detected in winter season in the polluted site, whereas, Bis (2-ethylhexyl) phthalate, and Pyridate were the only organic pollutants that were found in winter in the reference site. The accumulation patterns of organic pollutants percentage in the polluted site in summer in the muscles of O. niloticus were in the following order: Chlorpyrifos> Diamyl phthalate> Diisobutylphthalate> Di-n-butylphthalate> Diamyl phthalate> Bis (2-ethylhexyl) phthalate, whereas, in the reference site in summer, it was Chlorpyrifos> Chlorfenapyr> Di-n-butylphthalate> Diisobutylphthalate> Hexestrol> Di-nhexyl phthalate. The accumulation patterns of organic pollutants in the polluted site in winter in the muscles of O. niloticus, were in the following order: Bis(2-ethylhexyl)phthalate> Pyridate> Ethofumesate, whereas in the reference site it was; Bis (2-ethylhexyl)phthalate> Pyridate.

Rationale Prisons are major reservoirs of hepatitis C virus (HCV) in which a therapeutic approach has been particularly difficult so far. Prevalence of viral hepatitis C (HCV) is higher in prison environment in France than in the general population and is estimated to be 4,8%. The impact in prison environment is little-known as based on local studies. Inmate health care falls under USMP (prison setting medical unit), hospital specific units as by the january 18, 1994 law. Access to antiviral c treatment for inmates has always been difficult in France, would it be for interferon and ribavirin or use of protease inhibitors, with less than 20% of treated patients. French recommendations for HCV screening recommend systematic screening of inmates. The arrival of all oral therapies by direct antiviral agents (DAA) with shorter treatment times was an opportunity for doctors to propose a treatment and the patient to accept it. In 2014, the French guidelines recommended that HCV carriers in prison should systematically be treated independently of the stage of fibrosis. Objective of the Study PH8 Our objective was to evaluate the completion rate of an 8-week antiviral C treatment by sofosbuvir / ledipasvir regimen in non-cirrhotic genotype 1 patients in deprivation of liberty and achieve sustained virological response (SVR) and to measure the effectiveness of an 8-week treatment (by protocol analysis). Methodology prospective non-interventional multicenter trial among inmates with chronic hepatitis C genotype 1 with METAVIR fibrosis score F0 to F2 and who will receive a daily combination of sofosbuvir / ledipasvir for 8 weeks. Results 6 prison medical units included 115 consenting patients: there were 81% men, mean age 41 years (21 to 64 years). Route contamination was drug injection for 85%. HCV genotype was 1a for 74%, 1b for 24% and 2% none differenciated 1. Fibroscan mesure was available in 89 patients (mean score 3,5 KPa). Fibrotest was available in 37 patients with mean value 0.21. Eleven patients had Fibroscan and Fibrotest; 69% of patients were F0, 22% F1 and 9% F2. Average time between diagnosis and start of treatment was 3 weeks. We are sure that 109 patients (95%) completed DAA 8 weeks treatment; only 2 stopped DAA treatment before 8 weeks and 4 had no follow up after end of detention. HCV viral load was measured at W2 for 90 patients (78%), at W4 for 92 patients (78%), at end of treatment for 92 patients (78%), one month after treatment for 90 patients (78%) and 3 months after for 95 patients (93%). Only one viral load was positive, one month after treatment. Patient was retreated by sofosbuvir / velpastasvir. All HCV viral load 3 months after treatment negative; one patient took DAA only 6 weeks was cured. Conclusions In these study PH8, we observed completion rate of 94% for included patients in patient with 8 weeks ledipasvir/sofosbuvir regimen; data missed for only 4 patients and one relapsed. Short DAA treatment was efficient in prisoners and could be preferred in specific population.

Given limited knowledge regarding validity of the Titmus vision screener, we sought to compare visual acuity measurements obtained from the Titmus with that from the Snellen chart and assess the validity properties of the Titmus as a screening instrument to detect vision impairment. Visual acuity was measured in 150 participants recruited from an academic ophthalmology practice, using the Snellen chart as well as the Titmus vision screener. Visual acuities from the Titmus and Snellen were compared and validity of the Titmus vision screener was assessed by computing sensitivity and specificity. Using Snellen visual acuity as the reference standard, the sensitivity of the Titmus vision screener to detect vision impairment, defined as visual acuity worse than 20/40, was 92% (95% CI (72.5, 98.6)) and the specificity was 64% (95% CI (57.9, 70.1)). Comparisons of the precise visual acuity level revealed poor agreement between the two methods (weighted Kappa: 0.15, 95% CI (0.08, 0.21)). Visual acuities obtained from the Titmus were, on average, two lines worse than Snellen visual acuities. ((logMAR Snellen – logMAR Titmus) = - 0.19 ± 0.29, 95% confidence interval (CI) (-0.23, -0.16)). Titmus vision screener is a sensitive tool to detect visual impairment. However high false positive results and poor agreement with Snellen limits its widespread use in clinical applications.

Vision impairment and blindness remain a challenge in developing countries, especially in rural communities. Notwithstanding, VISION 2020 global initiative seeks to eliminate avoidable blindness by 2020. This community-based cross-sectional study aimed at determining the accessibility of ophthalmic services and barriers to its utilization in rural communities in the Upper Denkyira West District, Ghana. One-hundred and seventy participants from 5 randomly chosen rural communities in the district were included. Participants were interviewed using a structured questionnaire. Socio-demographic information, information regarding accessibility, utilization, and barriers to eye care services were obtained. Descriptive statistics were carried out using SPSS version 23. The Chi-squared test was employed to determine associations. P-values less than 0.05 at a confidence interval of 95% were considered significant. Only 21.8% of participants had had eye examination within the past 3 years, with over half of the examinations undertaken at screening grounds and health centres. Significant associations were found between ophthalmic services utilization and increasing age (p = 0.004), female gender (p = 0.027) and those who had a past history of eye problem(s) (p = 0.0010. The study found gross inadequate utilization of ophthalmic services mainly due to unavailable ophthalmic services in the rural district. Public health education and eye care interventions should prioritize and target rural populations. Key Messages This study found gross inadequate utilization of ophthalmic services mainly due to unavailable ophthalmic services in the rural district. Rural dwellers were thus compelled to resort to harmful eye care practices. Public health education and eye care interventions should prioritize and target rural populations

Objective: The aim of the present study is to determine the efficiency of third year ophthalmology residents from a tertiary hospital in performing preliminary retinal examination to identify eyes at risk retinopathy of prematurity on the basis of retinal fundus findings up to International Classification of Retinopathy of Prematurity (ICROP) Zone II. Methods: This is a single-center, cross-sectional, prospective comparative research conducted from June to October 2015 at a tertiary training hospital in the Philippines. All infants referred for retinopathy of prematurity screening within the study period where included. The presence of retinal vessel dilatation and tortuosity were identified by third year ophthalmology residents using indirect funduscopy. The residents’ fundus findings were then compared to that of a retina consultant who is proficient in the diagnosis and management of retinopathy of prematurity (ROP). The Kappa index was used to rate inter-observer agreement. The correlation between ROP risk factors and the presence of abnormal retinal vessels were assessed using odd ratio computations. Fisher’s exact test was used to determine the correlation between retinopathy of prematurity and the presence of retinal dilatation and tortuosity. The McNemar’s test was also applied to determine significant differences in the retinal findings of the consultant and ophthalmology residents. Results: A total of 82 eyes of 41 premature infants were evaluated to determine if retinal findings observed by ophthalmology residents were comparable to that of a retina consultant. Odds ratios show that age of gestation, birth weight, and history of blood transfusion are significantly associated with the presence of retinopathy of prematurity. Retinal vessel tortuosity and dilatation are also more common among infants diagnosed with retinopathy of prematurity. There was no significant difference between the retinal vascular findings of the retina consultant and the third year ophthalmology resident in terms of identifying retinal vessel dilatation and tortuosity (P < 0.05). Conclusion: After sufficient and in-depth ophthalmology training, third year ophthalmologists, who will be general ophthalmologists in the future, can reliably identify eyes at risk for severe retinopathy of prematurity on the basis of retinal vascular dilatation and/or tortuosity.

Diospyros malabarica (Desr.) Kostel synonym Diospyros peregrina Gurke (Family: Ebenaceae) is a medium sized evergreen tree commonly known as Kendu in Assamese. The plant has ethnomedicinal significance and used by various ethnic communities of North-East India to treat various disorders like dysentery, diabetes, diarrhea malaria, ulcer and wounds. However, detailed scientific information is not available to identify the plant material, in order to ascertain its quality and purity. Therefore, the present work was carried out to perform morpho-anatomical and physicochemical analysis of D. malabarica stem bark. The bark is externally dark brown to black in color and rough having characteristics odor and astringent taste. The microscopy of bark reveals the presence of polygonal thick walled cork, 3-4 layered phellogen, 7-8 layered phelloderm, stone cells, phloem fibers and medullary rays. Stem bark powder showed thick walled cork cells, thick walled elongated phloem fibers, lignified stone cells and rhomboidal crystals of calcium oxalate. Further, physicochemical analysis of the bark power showed loss on drying, total ash, water soluble ash, and acid insoluble ash as 6.2, 5.6, 1.1, 2.45, and 5.7% w/w respectively. The alcohol and water soluble extractives values of the stem bark were 10.6 and 16.8% w/w respectively. The result of preliminary phytochemical screening indicates presence of triterpenoids, saponins, tannins, flavonoids and sterols. The findings of this study will facilitate pharmacognostic standardization of the plant material and aid in the preparation of an herbal monograph for the species.

Pulmonary hypertension (PH) has become an increasingly recognized complication in sickle cell anaemia (SCA) and is a major cause of morbidity and mortality. Though the burden of SCA in sub-Saharan Africa is high, there is paucity of data on SCA-associated PH with little or no attention given to it in routine patient care. The current study therefore sought to determine the prevalence of PH and its associated risk factors among adult patients with SCA. This was a cross-sectional study involving 76 clinically stable, hydroxyurea-naive participants. We obtained socio-demographic and clinical history. Measurement of Tricuspid Regurgitant jet Velocity (TRV) was obtained via transthoracic echocardiography and lung function was assessed using spirometry and pulse oximetry. Other investigations were complete blood counts, free plasma haemoglobin, serum urea and creatinine. Twenty-five (32.9%) of study participants had elevated TRV (≥ 2.5m/s) on Doppler echocardiography, which was suggestive of raised pulmonary artery systolic pressure. There were significant associations between elevated TRV and steady-state haemoglobin (p < 0.001), blood urea level (p = 0.030), presence of chronic leg ulcers (p = 0.043) and oxygen saturation (p < 0.001) and these may be identifiable and modifiable risk factors for selective screening with echocardiography in a resource poor setting.

The Agency for Toxic Substances and Disease Registry (ATSDR) lists cadmium as one of its priority hazardous substances. The agency conducted a comprehensive literature review of cadmium and used the information to develop a toxicological profile that identified the full range of health effects associated with exposure to cadmium. It included an assessment that identified screening levels, termed health guidance values or minimal risk levels (MRLs), below which adverse health effects are not expected. In this paper, we describe how MRLs for cadmium are derived. For the acute inhalation MRL, the traditional no observed adverse effect level or lowest observed adverse effect level (NOAEL/LOAEL) approach is used; for the oral intermediate MRL, the benchmark dose (BMD) approach is used. MRLs were developed for the most sensitive route-specific end points, other than mortality and cancer that were sufficiently supported and justified by the data. These included an acute duration (1–14 day exposure) inhalation MRL of 0.03 µg Cd/m3 for alveolar histiocytic infiltration and focal inflammation in alveolar septa and an intermediate duration (15–365 day exposure) oral MRL of 0.5 µg Cd/kg/day for decreased bone mineral density

Antifungal antagonism of different fourteen plant essential oils was examined as natural agents against economic and hygienic effective three yeasts; the preservative efficacy of most potent anti-yeast essential oil in food sanitary was also tested. Study involved oils antifungal bioactivity screening against Saccharomycescerevisiae, Candida albicans,and Candida utilis. Study also included selection and invitro extraction of most bioactive oil, and evaluation of its antifungal minimal inhibitory concentrations (MICs). Control ofjuice spoilage by Saccharomycescerevisiae under the effect of in vitro oil extract different concentrations was also screened. Among the tested essential oils, apricot seed oil was the most bioactive anti-yeast agent. Two MIC values of apricot oil invitro extract, 12.5μgml-1 and 25μgml-1 were recorded. In juice samples, oil extract bioactivity increased gradually up to concentration 100μgml-1.Highest oil preservative ability was observed at oil concentration of and above 125μgml-1. Higher oil concentrations needed for juice preservation were found more than in vitro assay to give the same effect. Applying of apricot oil and some other plant essential oils could be used as an environmental safety mode in osmophilic food preservation and in Candidate diseases biocontrol.

This study examined the mediating role of alcohol use in the relationship between PTSD symptoms and trauma-related psychotic reactions. A total of 231 participants including 181 females were recruited via web advertisement and flyers. Alcohol use condition, trauma-related psychotic experience, and PTSD symptoms were measured by Feeling the need to Cut down, Annoyed by criticism, Guilty about drinking, and need for an Eye-opener in the morning (CAGE), Psychosis Screening Questionnaire (PSU) and Short screening scale for posttraumatic stress disorder (SSSP). All the participants were asked to finish the questionnaire package on the Internet and were interviewed later to validate the screening. Logistic regression was used to estimate the mediating effect of alcohol use. Results showed that alcohol use played a mediating role between PTSD symptoms and auditory hallucination while this effect didn’t exist between PTSD symptoms and paranoia. Findings indicated that hallucination and paranoia in people with PTSD symptoms were influenced by alcohol use in diverse ways.

Several interactions exist between thyroid and kidney function in many disorders. Many publications explored the relationship between thyroid diseases (TD) and chronic kidney diseases (CKD). However, the morphological thyroid changes in patients with CKD or End Stage Kidney disease (ESKD) were not fully explored. The aim of this study is to explore the morphological and the functional abnormalities of the thyroid gland among ESKD patients as detected by Doppler ultrasound. Patients and Methods: All of the 92 ESKD patients at our center were consented and included in the study. Demographic and clinical data and biochemical and hormonal profiles were recorded. Every patient received a dedicated ultrasound scan of the thyroid gland. GE ultrasound system with Doppler capabilities and high frequency transducer was used. Grey scale imaging and Doppler ultrasound were used to image the thyroid gland for every patient. Taking the thyroid morphology detected by ultrasound and the thyroid function as the dependent variables, all other parameters of age, sex, BMI, occupation, residence, duration of time on dialysis and other comorbilities were taken as independent variables and their relationship to the dependent variables was further studied using appropriate statistical tests. Results: Thyroid nodule(s) presence was found to be the most prevalent thyroid morphology detected on ultrasound scanning. Fifty three patients (57.6%) were found to have ultrasound detected nodule(s). The nodule presence was correlated to different independent variables and was found to significantly correlate with age only. The thyroid function as reflected by the level of thyroid hormones was also studied for correlation with the independent variables. No correlation was found between the thyroid function and the presence of nodules. Conclusion and Recommendation: Ultrasound detected nodules are very common in ESKD patients. The presence of nodule significantly correlates with patient age denoting its degenerative nature. Ultrasound screening of the thyroid in ESKD patients may be cost effective. However, we recommend a larger multicenter study for better results.

Drug-induced cardiotoxicity is one of the predominant reasons for drug attrition and withdrawals. This is of critical concern when potentially cardiotoxic drugs are administered to individuals with inherited arrhythmogenic cardiac diseases or with metabolic diseases such as obesity and diabetes, which are key risk factors for cardiovascular diseases. Pathophysiological alteration prevalent under such conditions can alter or exacerbate cardiotoxic responses. The growing incidence of obesity, diabetes and metabolic syndrome subject a significant percentage of the population to drug treatments, thereby augmenting their risk for drug-induced cardiovascular toxicity. Hence, screening for drug-induced cardiotoxicity early in the preclinical stages of drug development, by using appropriate human disease models, can be effective in ensuring safety in clinical trials and preventing late stage and post-marketing drug withdrawals owing to cardiotoxicity. The advent of human pluripotent stem cells (hPSC) and induced pluripotent stem cell (iPSC)-derived cardiomyocytes are revolutionizing safety/toxicity screening in human cells by providing relevant human-specific, renewable model systems to explore human drug toxicity. The ability to generate patient-specific iPSCs that can model cardiac diseases, now offers a valuable option that can further improve drug safety assessments and enable a more accurate prediction of toxicity that occurs in the representative population that are prescribed the drugs. Use of appropriate disease models will not only provide cost savings by decreasing potential drug attrition and withdrawals, seen with many drugs, but will also be a promising option to advance precision medicine

Introduction: Aflatoxins are cytotoxic andserve as one of the key risk factors of hepatocellular carcinoma. Currently, plants and extract are widely used as potential scavenging substances for the detoxification of mycotoxins. Thus, this study aims to investigate the activity of the crude ethanolic leaves extract from Alchorneacordifolia in aflatoxicosis prevention. Material and Methods: The phytochemical screening was performed through qualitative analysis based on coloring and/or precipitation reactions. Groups of rats were treated daily with a mixture dose of aflatoxin B1 (AFB1) at 150 µg/kg and the crude extract of Alchorneacordifolia at doses of 50, 100, and 300 mg/kg for 21 days. The body weight, biochemical, and histological assessments were determined. Results: The phytochemical screening revealed the presence of polyphenols, flavonoids, sterols and terpenoids, quinoid compounds, tannins catechic and alkaloids. AFB1 treatmentcaused a significant increase of transaminases, urea, and creatinine abundances but reduced the rates of albumin and total proteins. Alchorneacordifolia administration alleviated biochemical parameters and body weight gain compared with the AFB1 group (p<0.05). The histological lesions of organs (liver and kidney) caused by AFB1 were significantly improved after administration of the extract at a dose of 300 mg/kg. Conclusion: This plant plays a beneficial role in AFB1-induced injury and may be used in the treatment of aflatoxicosis.

Single-nucleotide polymorphisms (SNPs) in genes involved in immune responses and in the pharmacokinetics/pharmacodynamics of immunosuppressive drugs influence transplant outcomes of patients receiving the same immunosuppressive therapy. The aim of our preliminary study was to determine the SNPs profiles of ABCB1/MDR-1, UGT1A9, IMPDH2, IL-10 and TNF-α genes associated with acute rejection (AR) events in renal allograft recipients. DNA was extracted from whole blood samples of 220 individuals in 3 experimental groups; Case: 41 kidney transplant patients with AR event(s), Control I: 109 kidney transplant patients without AR event, Control II: 70 healthy blood donors. Acute rejection defined as rapid, unexplained rise in serum creatinine was biopsy-proven. 19 SNPs were analyzed by Sanger Sequencing. Analysis of allele and genotype frequencies and gene-disease association tests were performed. Allele frequencies of healthy persons are in line with ones reported from Europe indicating that the studied population is representative. Statistically significant differences only by the comparison of kidney transplant patients with AR event(s) and healthy individuals are found for rs2032582 and rs1045642 SNPs of ABCB1/MDR1, the latter is also not in Hardy-Weinberg equilibrium in our population. Patients with specific alleles for these SPNs are more prone to have acute rejection events. Certain allele variants of ABCB1/MDR1 by modifying the effectiveness of the drugs may compromise the success of the immunosuppressive therapy and put patients at higher risk to reject the new organ. Therefore screening for these polymorphisms before transplantation would help clinicians to more accurately personalize medications.

This study investigated the feasibility of using three-dimensional (3D) technology as a multi-functional visual stimulus to assist the clinical eye exam. Specifically, we examined: (1) whether the receding movement of a 3D fixation target into distance could relax the accommodation of non-cycloplegic hyperopic subjects so that accurate refraction measurements could be achieved; (2) the feasibility of using the left-eye and right-eye images from the 3D monitor as the light source to perform swinging-flashlight pupil tests; and (3) the implementation of 3D technology to interrupt the binocular visual/motor fusion as required for the clinical cover test to identify strabismus. Using a 3D TV to provide visual stimuli and a photoscreening (PS) device, near-infrared (NIR) eye images were acquired and analyzed for each of the three objectives. The result of accommodation test showed that with visual stimuli, the maximal hyperopic refractions could more accurately suggest the patients’ true refractions and the more hyperopic patients responded more to the 3D projected distance. However the very mild hyperopia did not show significant response. The pilot tests also showed distinguishable normal and abnormal pupillary responses with 3D image illumination and also the difference in phoria and tropia in the ocular alignment test using 3D stimuli.

Photorefraction (PR) methods have beenwidely used for pediatric vision screening since the 1980’s. While PR is easy to implement, the accuracy of refractive error measurements in humans has been unsatisfactory, largely due to the variations of intraocular scattering, the retinal reflectance, and pupil size. The objective of our studies was to clinically evaluate the accuracy of refraction measurements of an improved PR-based device, the Dynamic Ocular Evaluation System (DOES), and to investigate whether the accuracy is affected by the patient’s age, race, and pupil size, which are relevant to individual intraocular scattering and retinal reflectance. We performed DOES measurements in 99 volunteers (198 eyes) under two environmental light conditions and using four fixation targets. These results were compared to the standard clinical refraction testing performed the same day. The correlation and standard deviation were determined by Bland-Altman analysis. The influence of intraocular scattering, retinal reflectance, and pupil size was evaluated by comparing results from different age groups, races, and lighting conditions. In the region between -4 diopter (D) and +4D, the device showed a binocular refraction measurement accuracy of 0.45 D, 0.3 D, and 0.18 D root-mean-square (RMS) error (n=1337) for spherical equivalent and cross cylinders Jo and J45, respectively. Inaccuracy increased at high refraction (>4D). Age, race, and pupil size did not appear to significantly affect DOES PR measurement. This suggests that enhancements in the PR system and analysis may satisfactorily correct intersubject variability that currently limits the clinical use of PR devices and measurements.

Oral nutritional supplements (ONS) have been shown to improve patient outcomes in the hospital setting, but limited results from long-term care or community settings exist. Using electronic health records (EHRs) from 2009 to 2014 for both adult inpatients and outpatients, we compare the demographic and clinical characteristics of patients who received ONS (n = 1,251) with a non-ONS control group (n =25,513). Multivariable logistic regression modeling was used to describe and compare differences in baseline characteristics between the groups including age, sex, race, tobacco use, and comorbidities. We found that patients receiving ONS were older and sicker than control patients. Hospitalized ONS patients were more likely to be admitted from the emergency department and have a hospitalization within the last month prior to the index date. Our results suggest that there is a need for nutrition screening and incorporating nutrition status into the EHR as an important way to coordinate hospital and community medical care. ONS can be an important therapy for vulnerable populations in both the hospital and the community settings.

Idiopathic sudden sensorineural hearing loss (ISSHL) is a commonly seen otorhinolaryngology emergency, and its etiology is still a mystery. In this retrospective clinical study, we aimed to investigate the possible relationship of inflammatory markers derived from CBC such as neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), Red cell distribution width-to-platelet ratio (RPR), lymphocyte-to-monocyte ratio (LMR), mean platelet volume (MPV) and platelet distribution width (PDW) in ISSHL . A total of 50 idiopathic sudden hearing loss patients were included in the study. They were grouped according to their hearing healing levels as recovered, partially recovered and unrecovered. Also 47 age- and sex- matched healthy individuals created the control group. Their complete blood count parameters of NLR, LMR, PLR, RPR, PDW and MPV were recorded. The results were statistically compared to bring out a significant difference between the groups. There was no significant demographic difference between the groups. The comparison of patient group with control group reveal a significant difference in the NLR, LMR and PDW values (p<0.05). The remaining values were not statistically significant. The analysis of these values according to the recovery level of the ISSHL, there was no statistical difference between the groups (p>0.05). We demonstrated for the first time that LMR value was significantly elevated in ISSHL patients. NLR, LMR, and PDW might be indicative for diagnosis of ISSHL. However, we believe that using these parameters for the screening of the prognosis is a clinically useless exercise.

Objectives: This pilot study explored post-traumatic stress symptoms (PTSS) and moderate to severe psychological distress in a small sample of urban community-living adolescents seeking asylum in Australia. The study also examined the relationships between post-traumatic stress symptoms (PTSS) and psychological distress and school and family support and connectedness. Method: A cross-sectional survey examined PTSS (Abbreviated PTSD Checklist), psychological distress (Kessler-5) and school connectedness (California Healthy Kids Survey)53 in 27 adolescents seeking asylum (ages 12-17, mean 15.4) attending two independent secondary schools in Perth, the capital city of Western Australia. Results: In the sample, 63.0% (n=17, 1 missing) of adolescents exceeded the PTSS threshold (i.e. screened positive for Post-traumatic Stress Disorder) and 66.7% (n=18) exceeded the Kessler -5 threshold indicating moderate to severe psychological distress. Overall, 51.9 % (n=14, 1 missing) of adolescents screened above both thresholds suggesting co-occurrence of PTSD and moderate to severe psychological distress. Boys (x̄=15.0, SD=2.9) experienced higher psychological distress scores than girls (x̄=12.1, SD=4.5; p=0.071). Higher perceived support by an adult in school (r=0.13), and at home (r=0.28) were weakly associated with lower PTSS. Less time in Australia was weak-moderately associated with higher psychological distress (r=0.35). Weak associations between higher psychological distress and age (r=0.17) and those who felt more supported by an adult at home (r=0.17) were detected. Conclusion: Approximately two thirds of this group of community-living adolescents who were seeking asylum experienced post- traumatic stress symptoms or psychological distress; and more than one half experienced both. These pilot research findings suggest that adolescents who are seeking asylum and living in the Australian community are at risk of experiencing PTSD and moderate to severe psychological distress; research incorporating larger samples and longitudinal measurement is required. Screening, clinical assessment and examination of the immediate and long term impact, as well as implementation and evaluation of evidence-based mental health interventions, within these populations is also recommended.

Loss of muscle mass and functionality leads to increased risk for falls and onset of frailty, especially residents of long term care (LTC) homes. Hand grip strength (HGS) is emerging as a promising tool to measure muscle strength and a proxy for functionality. Given its promise as a screening tool, several studies report cut-offs below which measured strength was predictive of risk of poor mobility in older subjects. A scoping review was conducted to examine whether HGS was currently being used in LTC, as studies demonstrate hand grip strength as positively correlated with activities of daily living, implying increased dependence on caregivers including mealtimes. Of 19 published studies in 2015, only two report HGS use. As there is an association of grip strength with nutrition-related outcomes, hand grip strength should be used as part of nutritional assessment by dietitians in LTC, as poor muscle strength adversely affects activities of daily living that may impact intake.

Background: Colorectal cancer (CRC) screening by Fecal Immunohistochemical Testing (FIT) followed by colonoscopy reduces colorectal cancer mortality. Barriers to colonoscopy should be minimised. Objective: To compare psychological “risks” of colonoscopy in FIT positive (FIT+) subjects and those with Inflammatory Bowel Disease (IBD). Method: IBD patients undergoing colonoscopic CRC surveillance were age and gender matched with FIT+ individuals awaiting colonoscopy. Subjects completed Spielberger State and Trait Scales for current levels of anxiety, depression, anger and curiosity, versus long term personality tendencies. Results: 70 IBD respondents were matched with 70 FIT+ respondents, (57% male, mean age 57.6 years). FIT+ subjects demonstrated greater scores for state Anxiety (22.3 vs 20.3 p=0.024), Curiosity (24.3 vs 21.8 p=0.036), Anger (13.7 vs11.5 p=0.037) and Depression (23.8 vs21.2 p=0.002). Conclusion: FIT+ patients experience more anxiety and depression prior to their colonoscopy than IBD patients, which may reduce colonoscopy uptake and is important to address.

Purpose: To determine an appropriate time interval for conducting mass screening for glaucoma, it is important to gather information on the annual incidence rate. Thus, a retrospective cohort study was conducted to determine the annual incidence rate of visual field abnormalities (VFA) among a workplace cohort. Methods: In an initial visual field test using frequency doubling technology (FDT) perimetry conducted on 3443 employees (mean age 47.4 ± 8.9, men/women = 2967/476), no abnormalities were observed. Subjects were followed-up with annual perimetric testing for seven years, with VFA being determined using FDT test (FDT-VFA). Results: Using theKaplan–Meier method (log rank test, p < 0.001), cumulative FDT-VFA rates (SE) at seven years for subjects in their 30s, 40s, 50s, and 60s or older were found to be 3.0% (0.6), 4.2 % (0.6), 4.8 (0.8), and 11.3% (0.2), respectively. A linear fit to the Kaplan–Meier results yielded an annual incidence rate of 0.42%, 0.60%, 0.77%, and 1.60% for the 30s, 40s, 50s, and ≥60s age groups, respectively. Conclusion: Our data suggest that the annual incidence rate of VFA is <0.7% per year in subjects younger than 60 years of age; however, it increases to 1.6% per year in older subjects, thus suggesting that the monitoring frequency of glaucoma patients may need to be adjusted as a function of their age and be performed more frequently after the age of 60 years

Campylobacter infection has been detected in poultry processors at live bird markets in Sokoto, however the prevalence of Campylobacter species in more diverse group of the population is uncertain. For this purpose, 292 human fecal swabs from patients in four Government Hospitals in Sokoto State were analyzed for Campylobacter species using culture and phenotypic typing method. The prevalence rate of 55% was revealed in the tested samples while 56% and 55% were for males and females respectively. Campylobacter jejuni, C. coli and C. lari had 20%, 40% and 40% in males and 38%, 35% and 27% in females respectively. The prevalence rates of 60%, 52%, 45%, 41% and 80%,were revealed in age range of (less than 1-6, 7-13, 14-20, 21-55 and 56-76) yrs respectively. Furthermore, 70% and 43% prevalence rates were recorded in pregnant and non-pregnant women of reproductive age respectively. There was no statistical significant association (P>0.05) between Campylobacter infection and age range and sex, but the statistical association between infection and pregnancy was significant (P<0.05). The prevalence of Campylobacter species in patients as found in the various hospitals has revealed the level of environmental contamination in different homes in the state and the need to include Campylobacter in screening routine laboratory diagnosis of gastroenteritis in humans for appropriate treatment and management especially in young children, old adult and pregnant women.

Background and Objectives: The prevalence of abnormal cervical cytology in morbidly obese women using ThinPrep® liquid-based Pap Test™ and HPV DNA Test™ is unknown. We aimed to investigate whether women with morbid obesity have a higher frequency of abnormal Pap smears compared with nonobese women, and to explore the rate of Pap smear screening in morbidly obese women. Design and Setting: We conducted a retrospective study over five years in two general government hospitals in Dubai. Patients and Methods: We screened ThinPrep slides and HPV DNA of morbidly obese women and nonobese women. The age, ethnicity, demographic and socioeconomic backgrounds of the two groups were matched. We studied hypertension (HTN), diabetes (DM), infertility, sexually transmitted diseases (STD), connective tissue disease (CTD), immunosuppression and oral contraceptive pills (OCP) as potential risk cofactors. Results: Only 90 (29%) out of 310 morbidly obese women had had Pap tests. They showed more prevalence (P<0.05) of ASC-US, high-risk HPV DNA and LSIL 16 positive (18%) (95% CI: 7.0, and of endometrial AGCs {4 positive (4.5%) (95% CI: 0.3-13.5)} than the nonobese women (n=8175), {279 positive (3%) (95% CI: 3.0-3.8} , and {2 positive (0.024%) (CI:0.01-0.09)}. There were no endocervical AGCs, HSIL or squamous cancer in morbidly obese women. DM, HTN, OCPs, CTD and STD were more common in morbidly obese women having abnormal Pap smears. Conclusions: Low-grade squamous abnormalities, high-risk HPV, and endometrial AGCs are more frequent in morbidly obese women than in nonobese women. Women with morbid obesity have a low rate of cervical screening. This, among other factors, could increase the risk of these women to abnormal cervical cytology. This vulnerable group should benefit from more frequent cervical cytology screening. Appropriate clinical and educational measures should be implemented to encourage compliance to Pap smears. Weight reduction might help.

Objectives Antiretroviral pre-exposure prophylaxis (PrEP) against HIV acquisition has been shown to be safe and effective in populations at risk of HIV acquisition. We examined PrEP awareness, experience and acceptance among men who have sex with men (MSM) in southwest Switzerland. Methods Between 1st June 2011 and 31st August 2012, individuals attending 1) MSM screening clinics (Checkpoint Geneva) and 2) meeting areas were invited to complete an anonymous questionnaire covering sexual practices and PrEP awareness, experience and interest in participating in future PrEP trials. Results Of 918 men approached, 654 (71%) agreed to participate, the majority (536/654, 82%) enrolled via Checkpoint. Most participants (512/654, 78%) were homosexual; 21/654 (3.2%) disclosed being HIV-positive; 140/654 (21%) had unknown HIV status. Unprotected anal intercourse (UAI) with a partner of different or unknown HIV status (non-serosorting) was practised by 49% of participants during the preceding year, more by participants of positive / unknown HIV status than by those negative / undisclosed status (68% vs 43%, P<0.001). Awareness of PrEP was reported in 42% (very aware in 17% and slightly aware in 25%); Checkpoint participants were more aware than those from other venues (47% versus 16%, P<0.001). PrEP experience was low (1.5%); 20% expressed interest in participating in future PrEP trials. Conclusions This is the first study exploring MSM PrEP awareness in Switzerland. Although overall awareness was 42%, interest in participating in future PrEP trials was low, against high frequencies of UAI and non-serosorting. If interest in using PrEP in practice is similar, alternative measures to curb HIV transmission are required in this population.

Missed cancers have been reported at higher frequencies in the right colon despite optical colonoscopy screening. The purpose of this study was to determine if there are regional differences in haustral fold height between the ascending, transverse, and descending colon using CT colonography (CTC). 50 supine CTC datasets from 50 asymptomatic, adult patients were analyzed (NCI-CBIIT instance of the National Biomedical Imaging Archive). At least 5 consecutive, pairs of unobscured haustral folds in each colonic segment were necessary to be included in this study. Of an initial 201 patients, 151 were excluded due to suboptimal colonic distension, retained fluid, tortuosity, and diverticulosis. For each dataset, the heights of the non-dependent haustral folds were measured in the ascending, transverse, and descending colon on 2D multiplanar reformations. Differences in mean HFHs were assessed using a hierarchical generalized linear mixed model. A total of 2079 colonic folds were measured: 625 in the ascending colon (including the cecum), 687 in the transverse colon, and 767 in the descending colon. The mean number of folds measured per segment was 6.87 ± 2.11. Mean HFHs were significantly taller in the ascending colon (14.62 ± 5.47 mm) than in the transverse (9.49 ± 3.65mm) or descending (6.53 ± 3.12mm) colon; mean HFHs were also significantly taller in the transverse than the descending colon, (P<0.0001, for all comparisons). In conclusion, taller colonic haustral folds are present in the proximal colon and may contribute to more frequently missed lesions (e.g. polyps) in the right colon by conventional, optical colonoscopy.

Background: Despite its expense, labor and intrusiveness, polysomnography (PSG) is the gold standard for diagnosing obstructive sleep apnea (OSA). Recently, commercially available electronic activity monitors, such as Fitbit, have become widely accepted and can provide an estimate of sleep patterns for screening children with possible OSA. A previous study demonstrated Fitbit to be valid compared to PSG in adults. To date, these devices have not been extensively utilized for research in children with sleep disordered breathing (SDB). Objective: To evaluate the validity of the Fitbit activity monitor compared to PSG in children and adolescents with SDB. Methods: Data was collected from 14 children, ages 3 through 11, who were scheduled for a PSG during the study period. Fitbit was worn concurrently during the night of the PSG. Analyses were performed by comparing total sleep time, number of awakenings, sleep efficiency and wake after sleep onset (WASO) Fitbit parameters with the corresponding parameters measured by PSG using Spearman’s rho. Fitbit movement epochs were also compared to PSG epochs showing movement behavior. Results: Pilot data suggest that Fitbit demonstrates a high sensitivity for sleep, a low specificity for wake and a trend suggesting good association of movement measurements. Conclusion: Although Fitbit is not as accurate as PSG for determining wakefulness, it may be a useful screening device to assess gross sleep quality in children. Further studies are indicated to validate these findings.

Background: Lavender has been used for centuries, but its exposure has become part of the everyday life in our days. It is used in the alternative medicine, and as a flavouring component in soaps, cosmetics and in food products (chocolate, ice-cream, spices). The increasing number of exposures resulted the appearance of hypersensitivity- reactions. Objectives: A survey on the prevalence of lavender hypersensitivity was conducted by the Contact Dermatitis Work-Group of the Hungarian Dermatological Society in a multicentre, prospective study. Patients and Methods: 1509 consecutivedermatological patients of 7 dermatological centres were involved in this study. Results were based on the analyses of age distribution and characteristic clinical signs of the patients, on symptoms-localization, and on relevance of positive skin lavender oil test results as well as other associated contact hypersensitivities. Results: We detected 8 patients with lavender hypersensitivity (0.53%). Typical localisations of skin symptoms were face, eyelids and hands. Associated hypersensitivity to fragrance and balsam components were not detected. Conclusion: The lavender hypersensitivity of our patients couldn’t be detected by fragrance screening allergens.The use of lavender oil in cosmetics and foods is very popular. The different types of contacts may result further increase of the sensitivity rate worldwide.

Objective Measuring coronary artery calcification (CAC) enables to optimize cardiovascular risk-stratification also in patients with type 2 diabetes mellitus (T2D), however the prevalence of CAC in randomly selected patients with T2D is uncertain. For this purpose we set out to examine and compare the occurrence of CAC in unselected T2D patients. Design A randomly selected cohort of 1825 individuals, men and women, either 50 or 60 years old, were invited to the screening study. Traditional risk factors were obtained and a non-contrast CT-scan was performed to assess the CAC score. Results A total of 1211 individuals participated, of whom 54 (4%) had T2D while 1157 (96%) were without diabetes. CAC was present in 62% of the patients with T2D versus 44% in those without (p=0.013). Also the prevalence of traditionally risk factors was high in patients with T2D as compared to subjects without T2D. When adjusting for age, gender, smoking, hypertension and hypercholesterolemia in multivariate logistic regression, T2D was not associated with presence of CAC (OR=1.0; 95% confidence interval 0.5 - 2.0, p=0.94). Conclusions One-third of patients with T2D did not have any CAC, and T2D per se was not associated to CAC.

Background: Medullary Thyroid Cancer (MTC) is a rare malignancy, accounting for less than 3% of all thyroid cancers and causes significant morbidity and mortality. MTC is often due to an underlying mutation of the RET proto-oncogene, which can result in additional endocrinopathies that must be screened for pre-operatively. The project aim was to determine if surgical training background influenced patient pre-operative evaluation for MTC. Methods: A retrospective review was performed of patients undergoing thyroidectomy for MTC at a single academic institution. Patients were analyzed based on who performed the initial operative procedure, a surgeon with specific endocrine surgery training or a surgeon without. Results: From 1994 to 2011, 37 patients with MTC were identified. Thirty percent were managed by an endocrine surgeon and 70% by a non-endocrine surgeon. A complete thyroid work-up was done for all the patients managed by an endocrine surgeon vs. 38.5% of the non-endocrine surgeon patients (p<0.01). Appropriate preoperative endocrine screening was performed in 91% of the endocrine surgeon patients vs. 50% of the non-endocrine surgeon patients (p= 0.03). RET mutation genetic testing was done for all endocrine surgeon patients vs. 85% of non-endocrine surgeon patients (p= 0.30). Conclusion: Endocrine trained surgeons recognize and appropriately manage the complexity of MTC and associated endocrinopathies, more often than surgeons without an endocrine surgery background. This may result in optimized management of these patients.

Evidence shows that depressive symptoms are associated with faster progression to AIDS in HIV-infected populations. Physical symptoms, self-esteem, and emotional support have been reported to play a major role in contributing to depressive symptoms. However, comparisons of different sources of support—specifically family vs. friends— have only been made in a few previous HIV studies. Therefore, the objectives of this study among HIV-positive perinatal Thai women were to examine: 1) both the direct and indirect effects of physical symptoms and emotional support on depressive symptoms; 2) which source of support is more significant, family or friends; and 3) the direct effect of self-esteem on depressive symptoms. Results revealed that half of the participants experienced major depressive symptoms. Physical symptoms and self-esteem both had direct effects on depressive symptoms. Emotional support, from friends and family, had an indirect effect on depressive symptoms. Treating physical symptoms and increasing self-esteem through emotional support, could help decrease depressive symptoms in the target population. Finally, it is crucial that routine screening for depressive symptoms is established at all HIV clinics for perinatal women in Thailand.

Aims and Objectives: The incidence of cryptococcal meningitis caused by Cryptococcus neoformans has risen markedly over the past 20 years as a result of theHIV epidemic and increasing use of immunosuppressive therapies. The objectives of this study were to isolate and identify Cryptococcus neoformans from clinically suspected cases of fungal meningitis by conventional techniques and evaluate the role of C-reactive protein (CRP) as a serum or urine biomarker for the diagnosis and monitoring of patients with cryptococcal meningitis. Materials and Methods: Direct microscopic examination of the CSF samples from clinically suspected cases of fungal meningitis was done by India Ink staining for the capsule demonstration and isolation of the Cryptococcus neoformans was done by inoculation of the sample on Sabourauds dextrose agar. Latex agglutination test for the presence of cryptococcal antigen was done on sera, CSF and urine samples. C Reactive Protein levels were estimated in sera and urine. Result: Cryptococcal meningitis was diagnosed in 12 cases by culture and/or India Ink staining and/or latex agglutination assay for antigen detection in CSF. Only 8 (66.67%) and 1 (8.33 %) out of 12 samples were positive for cryptococcal antigen in sera and urine respectively. Whereas all the 12 patients were positive in the sera for CRP above the detection threshold limit, only 1 (8.33 %) patient had raised CRP in urine. CRP was raised two weeks after initiation of antifungal therapy in 3 of the above 12 sera and all these 3 cases turned out to be recurrent cases of cryptococcal meningitis. Conclusion Given the high incidence, morbidity and mortality associated with cryptococcal meningitis, it would be ideal if a screening test could be used to exclude this diagnosis based on the presence of biomarkers in serum or urine which would mean less discomfort for the patient in addition to decreased laboratory examination costs.
