MVPA. Weight status was not associated to MVPA(PE) . MVPA(PE) accounted for 16.8 +/- 8.5% of MVPA(DAY) , and 17.5 +/- 8.2% in overweight children. All children were more active on days with PE than on
<em>Strongyloides stercoralis</em> infection and re-infection in a cohort of children in Cambodia (Publications)
per child. Complete data were available for 302 participants. We observed infections in 24.2% and 22.5% of the children at baseline and at follow-up, respectively. At baseline, 73 children were treated for [...] Infection and re-infection rates of S. stercoralis among schoolchildren are considerably high. However, 68.5% of infected children remained free of infection for at least two years. A large-scale cohort study

of physical activity and disability. RESULTS: We analysed 3333 persons with a mean follow-up of 18±5.5years. Using hurdle models, moderate activity and high activity had a protective effect on the occurrence
A new alkamide with an endoperoxide structure from <em>Acmella ciliata</em> (Asteraceae) and its <em>in vitro</em> antiplasmodial activity (Publications)
revealed that 1 and 3 possess activity against the NF54 strain of the latter (IC50 values of 4.5 and 5.1 microM, respectively) while 2 was almost inactive. Compound 3 was also tested against multiresistant
Candidate-gene based GWAS identifies reproducible DNA markers for metabolic pyrethroid resistance from standing genetic variation in East African... (Publications)
gene, Vgsc). The putative associations were confirmed for two of the marker SNPs, in the P450 Cyp4j5 and the esterase Coeae1d by reproducible association with pyrethroid resistance in multiple field c [...] also showed evidence of association with resistance as did environmental humidity. Sequencing of Cyp4j5 and Coeae1d detected no resistance-linked loss of diversity, suggesting selection from standing variation

Estimated population-level impact of pneumococcal conjugate vaccines against all-cause pneumonia mortality among unvaccinated age groups in five Latin... (Publications)
aimed to assess the population-level impact of pediatric PCVs on all-cause pneumonia mortality among ≥5 years of age, and invasive pneumococcal disease (IPD) cases in Chile. METHODS: Demographic and mortality [...] mortality data from Argentina, Brazil, Chile, Colombia, and Mexico were collected considering the ≥ 5-year-old population, from 2000-2019, with 1,795,789 deaths due to all-cause pneumonia.
