Introduction: Healthcare-associated infections (HAIs) are a worldwide concern because of their magnitude and their human and financial cost. While nurses’ non-compliance of hygiene and asepsis measures is questioned, the rationale behind it is not fully understood. We hypothesized that nurses’ experiences and perceptions are one of the reasons for their non-compliance with prevention recommendations. Also, nurses’ caring approach would play an important role in patient safety. The objective of this study was to describe nurses’ experiences and perceptions of HAIs in a district hospital in Burkina Faso with the aim of developing a culture of safety in health care practices. Methods: Qualitative data were collected through unstructured interviews with twenty nurses from the Ziniaré district hospital. Data analysis followed the qualitative phenomenological method according to Giorgi. Results: Phenomenological analysis yielded the following themes: “an ignored reality”;“a denied responsibility”;and “a vulnerable problem”. These results show that nurses’ perception of the extent and seriousness of HAIs is low, and that they deny responsibility for their occurrence. As a result, HAIs are not always perceived as a concern. However, nurses deplore the situation, but remain optimistic about resolving the problem. Conclusion: These nurses’ perceptions of HAIs could explain their non-compliance with prevention recommendations. Corrective action could be redirected by raising awareness, continuing training, improving working conditions and involving all players, including patients and their families, in the fight against HAIs. .

Background: The diagnosis and treatment of active tuberculosis and the detection/management of latent tuberculosis infection (LTBI) cases are the two main strategies for the TB control, particularly in endemic countries. Tuberculin skin test (TST) and Interferon Gamma Release Assays (IGRAs) are tools for detection of LTBI. The objective of this study was to evaluate the performance of the TST and QuantiFERON-TB Gold Plus® (QTF-Plus) and to identify a threshold for TST in best agreement with QTF-Plus for LTBI detection in a high TB burden setting. Methods: In July 2020, a cross-sectional analytical study was performed for QFT-Plus using blood samples and TST in 101 individuals with a high risk of TB living in Bobo-Dioulasso, Burkina Faso. A crude comparison between both tests was done and receiver operating characteristic curve was generated to determine TST’s threshold. TST sensitivity, specificity, predictive values and accuracy were calculated. Adjusted agreement between TST and QFT-Plus was evaluated. Results: With the minimum threshold of positivity set at 5 mm for TST, the overall agreement between the latter and QFT-Plus was poor with a Kappa coefficient (κ) rated at 0.319 (95% CI: 0.131 - 0.508). This cut-off yielded a sensitivity of 94.12% (95% CI: 88.53 - 99.71), and very poor specificity of 36.4% (95% IC: 25.0 - 47.80). However, an adjusted cut-off set at 11 mm gave a better specificity of 72.73% (95% CI: 62.1 - 83.30) of TST and improved the PPV (86%). Moreover, concordance between both tests was improved with κ at 0.56 (95% CI: 0.385 - 0.728) and 80.20% of accuracy. Factors associated with discordance between TST (11 mm) and QFT-Plus results were BCG vaccination, OR = 7.53 (95% CI: 1.43 - 139.25), p = 0.05 and chronic cough, OR = 5.07 (95% CI: 1.27 - 20.43), p = 0.01. Conclusions: This study showed that using a minimal cut-off of 11mm for TST significantly improved the concordance between QTF-Plus (IGRA) and TST. Using the cut-off TST of

Introduction: Pesticides are currently an essential component of agricultural production techniques for controlling pests and weeds. In Burkina Faso, non-compliance with good practice in the use of pesticides poses a real health problem for the population. This study examines the health risks associated with pesticide management in rice-growing areas. Material and Methods: A field survey was conducted in Bama, involving farmers, focusing on their socio-demographic characteristics, pesticide usage, and health effects. Cholinesterase levels were measured in subsample of farmers using a portable device. Data were analysed using Microsoft Excel, calculating means and percentages for various practices. Health consultations, protection methods, and pesticide management were studied. Erythrocyte acetylcholinesterase activity was compared before and after treatment. Data were categorised into classes based on inhibition levels, and correlation analyses determined relationships between variables such as age, years of experience, and cholinesterase activity. Results: The results indicate that rice cultivation is mainly carried out by a fairly young population, with nearly 63% being under the age of 50. Common poor practices in pesticide use include improper storage and reuse of leftover pesticides. Seven types of pesticides were identified, including organophosphates such as glyphosate, which was used in 26.7% of cases. This organophosphate has resulted in class B poisoning, causing a 30% - 50% reduction in erythrocyte cholinesterase activity. The health effects of pesticide use are felt by agricultural farmers through various symptoms of poisoning. Conclusion: To reduce the occurrence of pesticide poisoning, it is essential to launch information and awareness campaigns among the population and farmers to promote safe practices in pesticide use in Bama, Burkina Faso.

Context: COVID-19 can spread rapidly in haemodialysis centres, leading to fatal outcomes. Implementing physical measures is crucial in limiting the spread of infection. Aims: To assess adherence to physical measures against SARS-Cov2 in haemodialysis patients. Methods and Material: From 13 to 19 July 2021, we administered the questionnaire to haemodialysis patients during or immediately after the dialysis session. The dependent variables were adherence to wearing masks, hand washing outside the dialysis centre, social distancing of at least 1.5 meters, and cough and sneeze hygiene. Statistical Analysis Used: Data were analyzed using Epi info software;descriptive statistics were presented as mean, headcount, and percentage;related factors were determined by multi-logistic regression. The significance level was 5%. The Health Research Ethics Committee approved the research protocol. Results: 142 patients were included (mean age: 42.5 ± 14 years). Wearing masks, hand-washing, social distancing, and coughing and sneezing hygiene were observed by 88%, 75%, 47%, and 60% of patients, respectively. Conclusion: Wearing masks was the most respected physical measure, while social distancing was the least respected.

Background: Although maternal mortality is declining in most countries, it remains a significant public health problem worldwide, with high rates, particularly in developing and insecure countries like ours. Objective: To study the epidemiological factors and factors associated with the occurrence of maternal death in the Gynecology-Obstetrics Department of University Hospital of Tengandogo. Method: It was a retrospective case-control study with a descriptive and analytical purpose over a period of 6 years from January 1, 2017 to December 31, 2022. Cases were women with maternal deaths during the study period. Data processing and analysis were performed using Stata version 13 software. Univariate and multivariate analyses were performed with Stata version 13 software, and logistic regression modeling was used to estimate crude and adjusted odds ratios (OR), their 95% confidence intervals (CI), and the threshold for statistical significance was set at a p value < 0.05. Results: A total of 372 patients were included in the study, including 146 cases of maternal death. The in-hospital maternal mortality rate was 1933 deaths per 100,000 live births. The average age was 28.5 years. 58.9% of patients lived in rural areas. Married patients accounted for 88.7% of cases. The average parity was 3. Direct obstetrical causes were the main causes of death, accounting for 72.6%. They were dominated by post-partum hemorrhage (24.2%), puerperal infection (18.6%), pre-eclampsia/eclampsia (16.1%) and retroplacental hematoma (8.9%). Chronic anemia (12.9%) was the main indirect obstetric cause. Risk factors associated with maternal death were primiparity (OR for paucigravida and multigravida at 0.05;P = 0.001);ambulance transport (OR for patients referred and brought in by personal vehicle = 0.3, p < 0.001) and vaginal delivery (OR for cesarean deliveries = 0.4, p < 0.001). Conclusion: To reduce maternal mortality in Burkina Faso, strategies such as educating women about danger signs d
