Lead exposure is associated with poor cognitive development in children. Very few studies in sub-Saharan Africa (SSA) have studied blood lead levels (BLLs) and non-gasoline sources of exposure in children. Data from a birth cohort in Benin (2011-2013) suggested that 58% of 1-year-old children had BLLs > 50 ug/L. We aimed to investigate the prevalence of elevated BLLs (>50 µg/L and >100 µg /L) among 425 of these children at 6 years of age in 2016-2018 and to compare BLLs between age 1 and 6 years, and study sources of lead at age 6 years. BLLs were analysed by inductively coupled plasma mass spectrometry. Multiple linear regression and quantile regressions were used to study potential sources of lead. The prevalence of BLLs > 50 µg/L in children was 59.5% (Geometric Mean (GM) 56.4 µg/L, 95% CI: 54.1-58.7) at 6 years of age compared to 54.8% (GM 56.5 µg/L, 95% CI: 53.4-59.6) at 1 year of age. The prevalence of children with BLLs > 100 µg/L decreased from 14.4% at 1 year of age to 8.2% at 6 years of age. After adjustment for all other covariates, consumption of peanuts more than once per month was significantly associated with a 22.0% (95% CI: 4.6, 42.5) increment in BLLs at age 6 years compared with no consumption. Consumption of bushmeat killed by lead bullets at age 6 years was associated with an increase in the higher percentiles of BLLs (P75) compared with the absence of this source. Other potential sources of lead associated with BLLs with marginal significance were consumption of rice, paternal occupational exposure, and the presence of activity with the potential use of lead. This prospective cohort confirms the persistently high prevalence of elevated BLLs in children residing in a rural region in the south of Benin, as well as the presence of multiple and continuous sources of lead. These results highlight the need for prevention programs to reduce and eliminate lead exposure in children.

Objectives: This study aims to evaluate musical pitch and timbre perception in children who stutter and compare the results with typically developing children.
Methods: A total of 50 participants were included in the study, consisting of 25 children with stuttering (mean age = 10.06 years; range 6-17 years) and 25 typically developing children (mean age = 10.
Objective: Elevated blood pressure (BP), even at prehypertensive levels, increases cardiovascular disease risk among people with HIV (PWH); yet international guidelines in low-income countries recommend treatment initiation at BP at least 140/90 mmHg. We determined the efficacy, feasibility, and acceptability of treating prehypertension in PWH in Haiti.
Design: An unblinded randomized clinical trial (enrolled April 2021-March 2022) with 12-month follow-up.

Background: Dialysis patients have high rates of fracture morbidity, but evidence on optimal management strategies for osteoporosis is scarce.
Objective: To determine the risk for cardiovascular events and fracture prevention effects with denosumab compared with oral bisphosphonates in dialysis-dependent patients.
Design: An observational study that attempts to emulate a target trial.

Background: Recent randomized controlled trials (RCTs) have investigated glucagon-like peptide-1 receptor agonists (GLP-1 RAs) and dual or triple co-agonists for weight loss among adults with overweight or obesity and without diabetes.
Purpose: To assess the efficacy and safety of GLP-1 RAs and co-agonists for the treatment of obesity among adults without diabetes.
Data Sources: MEDLINE, Embase, and Cochrane CENTRAL from inception to 4 October 2024.

Introduction: Anterior cruciate ligament reconstructions (ACLrs) unfortunately can require revision ACLr, or contralateral ACLr may be indicated (together subsequent ACLr). This study aimed to examine the rate of and factors associated with returning to the same surgeon.
Methods: Patients who underwent ACLr and subsequent ACLr within 3 years were abstracted from the PearlDiver database.
