abstract = {Background: Antiseptics, disinfectants, and hand hygiene products can be contaminated with bacteria and cause healthcare-associated infections, which are underreported from low- and middle-income countries. To better understand the user-related risk factors, we conducted a knowledge, awareness, and practice survey among hospital staff in sub-Saharan Africa. Methods: Self-administered questionnaire distributed among healthcare workers in three tertiary care hospitals (Burkina Faso, Benin, Democratic Republic of the Congo). Results: 617 healthcare workers (85.3% (para)medical and 14.7% auxiliary staff) participated. Less than half (45.5%) had been trained in Infection Prevention \& Control (IPC), and only 15.7% were trained \< 1 year ago. Near two-thirds (64.2%) preferred liquid soap for hand hygiene, versus 33.1% for alcohol-based hand rub (ABHR). Most (58.3%) expressed confidence in the locally available products. Knowledge of product categories, storage conditions and shelf-life was inadequate: eosin was considered as an antiseptic (47.5% of (para)medical staff), the shelf life and storage conditions (non-transparent container) of freshly prepared chlorine 0.5% were known by only 42.6% and 34.8% of participants, respectively. Approximately one-third of participants approved using tap water for preparation of chlorine 0.5% and liquid soap. Most participants (\> 80%) disapproved recycling soft-drink bottles as liquid soap containers. Nearly two-thirds (65.0%) declared that bacteria may be resistant to and survive in ABHR, versus 51.0% and 37.4% for povidone iodine and chlorine 0.5%, respectively. Depicted risk practices (n = 4) were ignored by 30 to 40% of participants: they included touching the rim or content of stock containers with compresses or small containers, storing of cotton balls soaked in an antiseptic, and hand-touching the spout of pump dispenser. Filling containers by topping-up was considered good practice by 18.3% of participants. Half (52.1%) of participants acknowledged indefinite reuse of containers. Besides small differences, the findings were similar across the study sites and professional groups. Among IPC-trained staff, proportions recognizing all 4 risk practices were higher compared to non-trained staff (35.9% versus 23.8%, p \< 0.0001). Conclusions: The present findings can guide tailored training and IPC implementation at the healthcare facility and national levels, and sensitize stakeholders’ and funders’ interest.},

abstract = {Objectives To determine the prevalence of multimorbidity, to identify which chronic conditions cluster together and to identify factors associated with a greater risk for multimorbidity in sub-Saharan Africa (SSA). Design Cross-sectional, multicentre, population-based study. Setting Six urban and rural communities in four sub-Saharan African countries. Participants Men (n=4808) and women (n=5892) between the ages of 40 and 60 years from the AWI-Gen study. Measures Sociodemographic and anthropometric data, and multimorbidity as defined by the presence of two or more of the following conditions: HIV infection, cardiovascular disease, chronic kidney disease, asthma, diabetes, dyslipidaemia, hypertension. Results Multimorbidity prevalence was higher in women compared with men (47.2% vs 35%), and higher in South African men and women compared with their East and West African counterparts. The most common disease combination at all sites was dyslipidaemia and hypertension, with this combination being more prevalent in South African women than any single disease (25% vs 21.6%). Age and body mass index were associated with a higher risk of multimorbidity in men and women; however, lifestyle correlates such as smoking and physical activity were different between the sexes. Conclusions The high prevalence of multimorbidity in middle-aged adults in SSA is of concern, with women currently at higher risk. This prevalence is expected to increase in men, as well as in the East and West African region with the ongoing epidemiological transition. Identifying common disease clusters and correlates of multimorbidity is critical to providing effective interventions.},

abstract = {Objectives We investigated progression through the care cascade and associated factors for people with diabetes in sub-Saharan Africa to identify attrition stages that may be most appropriate for targeted intervention. Design Cross-sectional study. Setting Community-based study in four sub-Saharan African countries. Participants 10 700 individuals, aged 40-60 years. Primary and secondary outcome measures The primary outcome measure was the diabetes cascade of care defined as the age-adjusted diabetes prevalence (self-report of diabetes, fasting plasma glucose (FPG) ≥7 mmol/L or random plasma glucose ≥11.1 mmol/L) and proportions of those who reported awareness of having diabetes, ever having received treatment for diabetes and those who achieved glycaemic control (FPG \<7.2 mmol/L). Secondary outcome measures were factors associated with having diabetes and being aware of the diagnosis. Results Diabetes prevalence was 5.5% (95% CI 4.4% to 6.5%). Approximately half of those with diabetes were aware (54%; 95% CI 50% to 58%); 73% (95% CI 67% to 79%) of aware individuals reported ever having received treatment. However, only 38% (95% CI 30% to 46%) of those ever having received treatment were adequately controlled. Increasing age (OR 1.1; 95% CI 1.0 to 1.1), urban residence (OR 2.3; 95% CI 1.6 to 3.5), hypertension (OR 1.9; 95% CI 1.5 to 2.4), family history of diabetes (OR 3.9; 95% CI 3.0 to 5.1) and measures of central adiposity were associated with higher odds of having diabetes. Increasing age (OR 1.1; 95% CI 1.0 to 1.1), semi-rural residence (OR 2.5; 95% CI 1.1 to 5.7), secondary education (OR 2.4; 95% CI 1.2 to 4.9), hypertension (OR 1.6; 95% CI 1.0 to 2.4) and known HIV positivity (OR 2.3; 95% CI 1.2 to 4.4) were associated with greater likelihood of awareness of having diabetes. Conclusions There is attrition at each stage of the diabetes care cascade in sub-Saharan Africa. Public health strategies should target improving diagnosis in high-risk individuals and intensifying therapy in individuals treated for diabetes.},

abstract = {Objective: To compare the risk factors for cardiometabolic disease between pre- and postmenopausal women from four sub-Saharan African countries. Study design: This cross-sectional study included 3609 women (1740 premenopausal and 1869 postmenopausal) from sites in Ghana (Navrongo), Burkina Faso (Nanoro), Kenya (Nairobi), and South Africa (Soweto and Dikgale). Demographic, anthropometric and cardiometabolic variables were compared between pre- and postmenopausal women, within and across sites using multivariable regression analyses. The sites represent populations at different stages of the health transition, with those in Ghana and Burkina Faso being rural, whilst those in Kenya and South Africa are more urbanised. Main outcome measures: Anthropometric and cardiometabolic variables. Results: The prevalence rates of risk factors for cardiometabolic disease were higher in South (Soweto and Dikgale) and East (Nairobi) Africa than in West Africa (Nanoro and Navrongo), irrespective of menopausal status. Regression models in combined West African populations demonstrated that postmenopausal women had a larger waist circumference (β = 1.28 (95 % CI: 0.58; 1.98) cm), log subcutaneous fat (β =0.15 (0.10; 0.19)), diastolic (β = 3.04 (1.47; 4.62) mm Hg) and log systolic (β = 0.04 (0.02; 0.06)) blood pressure, log carotid intima media thickness (β = 0.03 (0.01; 0.06)), low-density lipoprotein cholesterol (β = 0.14 (0.04; 0.23) mmol/L) and log triglyceride (β= 0.10 (0.04; 0.16)) levels than premenopausal women. No such differences were observed in the South and East African women. Conclusions: Menopause-related differences in risk factors for cardiometabolic disease were prominent in West but not East or South African study sites. These novel findings should inform cardiometabolic disease prevention strategies in midlife women specific to rural and urban and peri-urban locations in sub-Saharan Africa.},

Consequently, few health-care establishments have the required resources to diagnose and manage patients with COVID-19, and fewer still have intensive care facilities for severely ill patients with COVID. Furthermore, there is a widespread scarcity of qualified health-care staff. The aim of this study was to explore the experiences of patients with COVID-19 who recovered after being cared for in Bobo Dioulasso and Ouagadougou. Using individual semistructured interviews, we performed a cross-sectional qualitative, descriptive study from June 12 to 30, 2020 with the aid of 13 well-educated patients who had survived COVID-19. The results reveal that prior to hospital admission, the main reason that prompted patients to seek care was onset of symptoms of COVID-19, regardless of whether they had been in contact with suspected or confirmed cases. Transmission was mainly believed to have occurred in the community, in the hospital, and during travel. Patient management was punctuated by frequent self-medication with medicinal plants or pharmaceutical drugs. The participants reported a negative perception of hospitalization or home-based management, with several forms of stigmatization, but a positive perception influenced by the satisfactory quality of management in health-care centers. This report of patient experiences could be helpful in improving the management of COVID-19 in Burkina Faso, both in the health-care setting and in home-based care.},

Meta-analysis with four other African cohorts (N = 23,718) provides supporting evidence for the LDL-C association with the GATB/FHIP1A region and identifies a novel triglyceride association signal close to the FHIT gene (P-value =2.66 × 10(-8)). Our data enable fine-mapping of several well-known lipid-trait loci including LDLR, PMFBP1 and LPA. The transferability of signals detected in two large global studies (GLGC and PAGE) consistently improves with an increase in the size of the African replication cohort. Polygenic risk score analysis shows increased predictive accuracy for LDL-C levels with the narrowing of genetic distance between the discovery dataset and our cohort. Novel discovery is enhanced with the inclusion of African data.},

abstract = {BACKGROUND: Low birth weight (LBW) is a major factor of neonate mortality that particularly affects developing countries. However, the scarcity of data to support decision making to reduce LBW occurrence is a major obstacle in sub-Saharan Africa. The aim of this research was to determine the prevalence and associated factors of LBW at the Yako health district in a rural area of Burkina Faso. METHODS: A cross sectional survey was conducted at four peripheral health centers among mothers and their newly delivered babies. The mothers' socio-demographic and obstetrical characteristics were collected by face-to-face interview or by review of antenatal care books. Maternal malaria was tested by standard microscopy and neonates' birth weights were documented. Multivariate logistic regression was used to determine factors associated with LBW. A p-value \< 0.05 was considered statistically significant. RESULTS: Of 600 neonates examined, the prevalence of low birth weight was 11.0%. Adjustment for socio-demographic characteristic, medical conditions, obstetrical history, malaria prevention measures by multivariate logistic regression found that being a primigravid mother (aOR = 1.8, [95% CI: 1.1-3.0]), the presence of malaria infection (aOR = 1.9, [95% CI: 1.1-3.5]), the uptake of less than three doses of sulfadoxine-pyrimethamine for the intermittent preventive treatment of malaria in pregnancy (IPTp-SP) (aOR = 2.2, [95% CI: 1.3-3.9]), the presence of maternal fever at the time of delivery (aOR = 2.8, [95% CI: 1.5-5.3]) and being a female neonate (aOR = 1.9, [95% CI: 1.1-3.3]) were independently associated with an increased risk of LBW occurrence. The number of antenatal visits performed by the mother during her pregnancy did not provide any direct protection for low birth weight. CONCLUSION: The prevalence of LBW remained high in the study area. Maternal malaria, fever and low uptake of sulfadoxine-pyrimethamine doses were significantly associated with LBW and should be adequately addressed by public health interventions.},

abstract = {BACKGROUND: Malaria in endemic countries is often asymptomatic 

 during pregnancy, but it has substantial consequences for both 

 the mother and her unborn baby. During pregnancy, anaemia is an 

 important consequence of malaria infection. In Burkina Faso, the 

 intensity of malaria varies according to the season, albeit the 

 prevalence of malaria and anaemia as well as their risk factors, 

 during high and low malaria transmission seasons is 

 underexplored at the household level. METHODS: Data of 1751 

 pregnant women from October 2013 to March 2014 and 1931 pregnant 

 women from April 2017 to June 2017 were drawn from two 

 cross-sectional household surveys conducted in 24 health 

 districts of Burkina Faso. Pregnant women were tested for 

 malaria in their household after consenting. Asymptomatic 

 carriage was defined as a positive result from malaria rapid 

 diagnostic tests in the absence of clinical symptoms of malaria. 

 Anaemia was defined as haemoglobin level less than 11 g/dL in 

 the first and third trimester and less than 10.5 g/dL in the 

 second trimester of pregnancy. RESULTS: Prevalence of 

 asymptomatic malaria in pregnancy was estimated at 23.9% (95% 

 CI 20.2-28.0) during the high transmission season 

 (October-November) in 2013. During the low transmission season, 

 it was 12.7% (95% CI 10.9-14.7) between December and March in 

 2013-2014 and halved (6.4%; 95% CI 5.3-7.6) between April and 

 June 2017. Anaemia prevalence was estimated at 59.4% (95% CI 

 54.8-63.8) during the high transmission season in 2013. During 

 the low transmission season, it was 50.6% (95% CI 47.7-53.4) 

 between December and March 2013-2014 and 65.0% (95% CI 

 62.8-67.2) between April and June, 2017. CONCLUSION: This study 

 revealed that the prevalence of malaria asymptomatic carriage 

 and anaemia among pregnant women at the community level remain 

 high throughout the year. Thus, more efforts are needed to 

 increase prevention measures such as IPTp-SP coverage in order 

 to reduce anaemia and contribute to preventing low birth weight 

 and poor pregnancy outcomes.},

 mass index (BMI), waist (WC), hip circumferences (HC), visceral 

 (VAT) and subcutaneous adipose tissue (SCAT) using B-mode 

 ultrasound were measured. Ultrasonography of left and right far 

 wall CIMT of the common carotid artery was used as an indicator 

 of subclinical atherosclerosis. Individual participant data 

 meta-analyses were used to determine the associations between 

 adiposity phenotypes and CIMT in the pooled sample while 

 adjusted multivariable linear regression analyses were used for 

 site specific analyses. Results: Data were obtained from 9,010 

 adults (50.3% women and a mean age of 50$pm$ 6years). Men had 

 higher levels of visceral fat than women while women had higher 

 BMI, waist and hip circumference and subcutaneous fat than men 

 at all sites except Burkina Faso. In the pooled analyses, BMI 

 ($beta$-value [95% CIs]: 19.5 [16.8, 22.3] $mu$m) showed the 

 strongest relationship with CIMT followed by VAT (5.86 [4.65, 

 7.07] $mu$m), SCAT (5.00 [2.85, 7.15] $mu$m), WC (1.27 [1.09, 

 1.44] $mu$m) and HC (1.23 [1.04, 1.42] $mu$m). Stronger 

 associations were observed in men than in women. Conclusion: 

 Obesity within SSA will likely result in higher levels of 

 atherosclerosis and promote the occurrence of cardio- and 

 cerebrovascular events, especially in males, unless addressed 

 through primary prevention of obesity in both rural and urban 

 communities across Africa. The inverse association of VAT with 

 CIMT in Burkina Faso and Ghana requires further investigation. 

 Highlights: All adiposity phenotypes were positively associated 

 with common carotid intima-media thickness (CIMT) in the entire 

 cohort (pooled analyses).BMI had the strongest association with 

 CIMT compared to other phenotypes.The magnitude of association 

 between adiposity phenotypes and CIMT was higher in men than in 

 women.Subcutaneous adipose tissue was inversely associated with 

 CIMT only in women.An unexpected finding was the inverse 

 association of visceral adipose tissue with CIMT in Burkina Faso 

 and Ghana.},
