Knowledge and management of WEEE by independent repairers in the city of Bouake in a context of health and environmental risk, 2022

Studies on waste management in Côte d'Ivoire are mostly focused on household and solid waste. It is appropriate to take a sustained look at the management of electrical and electronic equipment waste to better guide policies in this area. This work is a cross-sectional study covering the period from April 1, 2022 to June 30, 2022. The aim was to determine the knowledge and practices of the independent electrical and electronic repairers of the city of Bouaké in terms of electrical and electronic equipment waste (WEEE) management. A comprehensive sample of 307 people was interviewed by means of a questionnaire. The repairers interviewed had already heard of WEEE in 47.2% of cases. They had a good level of knowledge of WEEE in 85.5% of cases. In the final model in multivariate analysis, only the possession of a radio set at home had a significant influence on knowledge of WEEE. Repairers were unaware of the existence of D3E management legislation in 60.7% of cases; apart from humans (84.8%) who were most exposed to the dangers of inappropriate management of WEEE, other entities (air, soil, water, animals) would be polluted according to 36.6, 35.2, 4.1, and 3.4% of repairers, respectively. The most feared type of harm reported is injury (95.65%). Subjects dumped WEEE in a municipal landfill in 32.4% of cases. Sale, empowerment of pre-collection agents, and handing over to a recycling professional, cumulatively represent the most common practice (66.9%).

Catastrophic health expenditure in sub-Saharan Africa: systematic review and meta-analysis

Objective To estimate the incidence of, and trends in, catastrophic health expenditure in sub-Saharan Africa. Methods :We systematically reviewed the scientific and grey literature to identify population-based studies on catastrophic health expenditure in sub-Saharan Africa published between 2000 and 2021. We performed a meta-analysis using two definitions of catastrophic health expenditure: 10% of total household expenditure and 40% of household non-food expenditure. The results of individual studies were pooled by pairwise meta-analysis using the random-effects model. Findings : We identified 111 publications covering a total of 1 040 620 households across 31 sub-Saharan African countries. Overall, the pooled annual incidence of catastrophic health expenditure was 16.5% (95% confidence interval, CI: 12.9­20.4; 50 datapoints; 462 151 households; I2 = 99.9%) for a threshold of 10% of total household expenditure and 8.7% (95% CI: 7.2­10.3; 84 datapoints; 795 355 households; I2 = 99.8%) for a threshold of 40% of household non-food expenditure. Countries in central and southern sub-Saharan Africa had the highest and lowest incidence, respectively. A trend analysis found that, after initially declining in the 2000s, the incidence of catastrophic health expenditure in sub-Saharan Africa increased between 2010 and 2020. The incidence among people affected by specific diseases, such as noncommunicable diseases, HIV/AIDS and tuberculosis, was generally higher. Conclusion :Although data on catastrophic health expenditure for some countries were sparse, the data available suggest that a non-negligible share of households in sub-Saharan Africa experienced catastrophic expenditure when accessing health-care services. Stronger financial protection measures are needed.

Degree of Bacterial Contamination and Antibiotic Susceptibility Pattern of Isolates from Housekeeping Surfaces in Operating Rooms and Surgical Wards at Jimma University Specialized Hospital; South West Ethiopia

The role of the hospital environment as a reservoir of potential pathogens has received increasing attention. There are several reports demonstrating contamination of a wide variety of environmental sites in operating rooms (ORs) and surgical wards (SWs) which lead to nosocomial spread. To determine the degree of bacterial contamination and antibiotic susceptibility pattern of isolates from floor and tabletop surfaces in ORs and SWs at Jimma University Specialized Hospital (JUSH). A cross sectional study was conducted on 144 floor and tabletop surfaces from October to January 2009/2010. Samples were investigated for identification of bacterial species following standard procedures and antimicrobial susceptibility tests were performed using disc diffusion technique. The data was analyzed using SPSS version 16 and compared with the proposed standard value. The mean aerobic colony counts (ACCs) for tabletop surfaces (34 CFU/cm2) and floors (19CFU/cm2) in SWs were significantly higher than the set ACC standard for hand contact surfaces ( 5 CFU/cm2) P 0.00. The ACCs obtained from tabletop surfaces (6.2 CFU/cm2) and floors (10.1CFU/cm2) in ORs were also exceeding the standard. Over 55of gram negative bacteria were identified from Critical Zone of ORs. Staphylococcus aureus was the must frequently isolated bacterium accounting 33.3followed by Escherichia coli and Klebsiella spp each with 11.1. Moreover; S. aureus showed 100resistance to methicillin and multidrug resistant Enterobacteriaceae were also seen in more than 90of isolates. An increased bacterial contamination was measured in both ORs and SWs of the JUSH and the isolated bacteria were also resistant for most of the antibiotics used as a treatment options in the study area. Therefore; appropriate infection control measures needs to be taken to keep the contamination level within the proposed standard
