abstract = {BACKGROUND: Malaria in pregnancy can result in placental infection with fetal implications. This study aimed at assessing placental malaria (PM) prevalence and its associated factors in a cohort of pregnant women with peripheral malaria and their offspring. METHOD: The data were collected in the framework of a clinical trial on treatments for malaria in pregnant women . Placental malaria (PM) was diagnosed by histopathological detection of parasites and/or malaria pigment on placenta biopsies taken at delivery. Factors associated with PM were assessed using logistic regression. RESULTS: Out of 745 biopsies examined, PM was diagnosed in 86.8 % of women. Acute, chronic and past PM were retrieved in 11 (1.5 %), 170 (22.8 %), and 466 (62.6 %) women, respectively. A modifying effect was observed in the association of gravidity or anemia at the study start with pooled PM (presence of parasites and/or malaria pigment). In women under 30, gravidity ≤ 2 was associated with an increased prevalence of pooled PM but in women aged 30 years or more, gravidity was no more associated with pooled PM (OR 6.81, 95 % CI 3.18 - 14.60; and OR 0.52, 95 % CI 0.10 - 2.76, respectively). Anemia was associated with pooled PM in women under 30 (OR 1.96, 95 % CI 1.03 - 3.72) but not in women aged 30 years or more (OR 0.68, 95 % CI 0.31 - 1.49). Similarly, the association of gravidity with past-chronic PM depended also on age. A higher prevalence of active PM was observed in women under 30 presenting with symptomatic malaria (OR 3.79, 95 % CI 1.55 - 9.27), while there was no significant increase in the prevalence of active PM (presence of parasites only) in women with symptomatic malaria when aged 30 years or more (OR 0.42, 95 % CI 0.10 - 1.75). In women with chronic PM, the prevalence of low birth weight or prematurity was the highest (31.2 %) as compared with past PM or no PM. CONCLUSION: Despite the rapid diagnosis and efficacious treatment of peripheral infection, the prevalence of placental malaria remained high in women with P. falciparum peripheral infection in Nanoro, especially in younger women This underlines the importance of preventive measures in this specific group.},

 reported to be low but there is little individual-level evidence 

 on the severity of the disease. This study examined the clinical 

 spectrum and outcome of patients monitored in COVID-19 care 

 centres (CCCs) in two West-African countries. METHODS: Burkina 

 Faso and Guinea set up referral CCCs to hospitalise all 

 symptomatic SARS-CoV-2 carriers, regardless of the severity of 

 their symptoms. Data collected from hospitalised patients by 

 November 2020 are presented. RESULT: A total of 1,805 patients 

 (64% men, median age 41 years) were admitted with COVID-19. 

 Symptoms lasted for a median of 7 days (IQR 4-11). During 

 hospitalisation, 443 (25%) had a SpO2 \< 94% at least once, 237 

 (13%) received oxygen and 266 (15%) took corticosteroids. 

 Mortality was 5% overall, and 1%, 5% and 14% in patients 

 aged \<40, 40-59 and $geq$60 years, respectively. In 

 multivariable analysis, the risk of death was higher in men (aOR 

 2.0, 95% CI 1.1; 3.6), people aged $geq$60 years (aOR 2.9, 

 95% CI 1.7; 4.8) and those with chronic hypertension (aOR 2.1, 

 95% CI 1.2; 3.4). CONCLUSION: COVID-19 is as severe in Africa 

 as elsewhere, and there must be more vigilance for common risk 

 factors such as older age and hypertension.},

abstract = {BACKGROUND: Socioeconomic inequalities between and within countries lead to disparities in the use of health services. These disparities could lead to child  mortality in children under 5 years by depriving them of healthcare. Therefore,  initiatives to remove healthcare fees such as the Free Healthcare Initiative (FHCI)  adopted in Sierra Leone can contribute to reducing these inequities in  healthcare-seeking for children. This study aimed to assess the socioeconomic  inequalities in healthcare-seeking for children under 5 years of age before and  after the implementation of the FHCI. METHODS: Data were included on 1207, 2815,  1633, and 1476 children under 5 years of age with fever from the 2008, 2013, 2016,  and 2019 nationwide surveys, respectively. Concentration curves were drawn for the  period before (2008) and after (2013-2019) the implementation of the FHCI to assess  socioeconomic inequalities in healthcare-seeking. Finally, Erreyger's corrected  concentration indices were calculated to understand the magnitude of these  inequalities. RESULTS: Before the implementation of the FHCI, there were  inequalities in healthcare-seeking for children under five (Erreyger's corrected  concentration index (CI) = 0.168, standard error (SE) = 0.049; p \< 0.001) in favor  of the wealthy households. These inequalities decreased after the implementation of  the FHCI (CI = 0.061, SE = 0.033; p = 0.06 in 2013, CI = 0.039, SE = 0.04; p = 0.32  in 2016, and CI = - 0.0005, SE = 0.362; p = 0.98 in 2019). Furthermore, before the  implementation of the FHCI, a significant pro-rich inequality in the districts of  Kenema (CI = 0.117, SE = 0.168, p = 0.021), Kono (CI = 0.175, SE = 0.078, p = 0.028)  and Western Area Urban (CI = 0.070, SE = 0.032, p = 0.031) has been observed. After  the implementation of the FHCI in 2019, these disparities were reduced, 11 of the 14  districts had a CI around the value of equality, and only in 2 districts the  pro-rich inequality were significant (Western Area Urban (CI = 0.035, SE = 0.016,  p = 0.039) and Western Area Rural (CI = 0.066, SE = 0.030, p = 0.027)). CONCLUSION:  The results of this study demonstrated that socio-economic inequalities in  healthcare-seeking for children have been considerably reduced after the FHCI in  Sierra Leone. To further reduce these inequalities, policy actions can focus on the  increase of availability of health services in the districts where the  healthcare-seeking remained pro-rich.},

abstract = {BACKGROUND: For uncomplicated Plasmodium falciparum malaria, 

 highly efficacious single-dose treatments are expected to 

 increase compliance and improve treatment outcomes, and thereby 

 may slow the development of resistance. The efficacy and safety 

 of a single-dose combination of artefenomel (800 mg) plus 

 ferroquine (400/600/900/1200 mg doses) for the treatment of 

 uncomplicated P. falciparum malaria were evaluated in Africa 

 (focusing on children $\leq$ 5 years) and Asia. METHODS: The 

 study was a randomized, double-blind, single-dose, multi-arm 

 clinical trial in patients aged \> 6 months to 5 years and 20 

 Asian patients. None of the treatment arms met the target 

 efficacy criterion for PCR-adjusted ACPR at Day 28 (lower limit 

 of 95% confidence interval [CI] \> 90%). PCR-adjusted ACPR at 

 Day 28 [95% CI] in the PP Set ranged from 78.4% [64.7; 88.7%] 

 to 91.7% [81.6; 97.2%] for the 400 mg to 1200 mg ferroquine 

 dose. Efficacy rates were low in Vietnamese patients, ranging 

 from 20 to 40%. A clear relationship was found between drug 

 exposure (artefenomel and ferroquine concentrations at Day 7) 

 and efficacy (primary endpoint), with higher concentrations of 

 both drugs resulting in higher efficacy. Six distinct kelch-13 

 mutations were detected in parasite isolates from 10/272 African 

 patients (with 2 mutations known to be associated with 

 artemisinin resistance) and 18/20 Asian patients (all C580Y 

 mutation). Vomiting within 6 h of initial artefenomel 

 administration was common (24.6%) and associated with lower 

 drug exposures. CONCLUSION: The efficacy of 

 artefenomel/ferroquine combination was suboptimal in African 

 children aged $\leq$ 5 years, the population of interest, and 

 vomiting most likely had a negative impact on efficacy. Trial

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.},

abstract = {Background: Obesity and adipose tissue distribution contribute 

 to an increased risk of cardiovascular disease (CVD) by 

 promoting atherosclerosis. This association has been poorly 

 studied in sub-Saharan Africa (SSA) despite the rising 

 prevalence of cardiovascular disease. Objectives: We determined 

 the association between various adiposity phenotypes and carotid 

 intima-media thickness (CIMT), a proxy of subclinical 

 atherosclerosis, in a large SSA population. Methods: A 

 population-based cross-sectional study was performed from 

 2013-2016 in Burkina Faso, Ghana, Kenya and South Africa. Body 

 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.},

abstract = {BACKGROUND: Absolute numbers of COVID-19 cases and deaths 

 reported to date in the sub-Saharan Africa (SSA) region have 

 been significantly lower than those across the Americas, Asia 

 and Europe. As a result, there has been limited information 

 about the demographic and clinical characteristics of deceased 

 cases in the region, as well as the impacts of different case 

 management strategies. METHODS: Data from deceased cases 

 reported across SSA through 10 May 2020 and from hospitalized 

 cases in Burkina Faso through 15 April 2020 were analyzed. 

 Demographic, epidemiological and clinical information on 

 deceased cases in SSA was derived through a line-list of 

 publicly available information and, for cases in Burkina Faso, 

 from aggregate records at the Centre Hospitalier Universitaire 

 de Tengandogo in Ouagadougou. A synthetic case population was 

 probabilistically derived using distributions of age, sex and 

 underlying conditions from populations of West African countries 

 to assess individual risk factors and treatment effect sizes. 

 Logistic regression analysis was conducted to evaluate the 

 adjusted odds of survival for patients receiving oxygen therapy 

 or convalescent plasma, based on therapeutic effectiveness 

 observed for other respiratory illnesses. RESULTS: Across SSA, 

 deceased cases for which demographic data were available were 

 predominantly male (63/103, 61.2%) and aged \>50 years (59/75, 

 78.7%). In Burkina Faso, specifically, the majority of deceased 

 cases either did not seek care at all or were hospitalized for a 

 single day (59.4%, 19/32). Hypertension and diabetes were often 

 reported as underlying conditions. After adjustment for sex, age 

 and underlying conditions in the synthetic case population, the 

 odds of mortality for cases not receiving oxygen therapy were 

 significantly higher than for those receiving oxygen, such as 

 due to disruptions to standard care (OR 2.07; 95% CI 

 1.56-2.75). Cases receiving convalescent plasma had 50% reduced 

 odds of mortality than those who did not (95% CI 0.24-0.93). 

 CONCLUSIONS: Investment in sustainable production and 

 maintenance of supplies for oxygen therapy, along with messaging 

 around early and appropriate use for healthcare providers, 

 caregivers and patients could reduce COVID-19 deaths in SSA. 

 Further investigation into convalescent plasma is warranted 

 until data on its effectiveness specifically in treating 

 COVID-19 becomes available. The success of supportive or 

 curative clinical interventions will depend on earlier treatment 

 seeking, such that community engagement and risk communication 

 will be critical components of the response.},
