Effect of number of hours and days of accelerometer use on physical activity estimates in adolescents

Abstract The study analyzed the effect of number of hours and days of accelerometer use on estimates of physical activity (PA) time in adolescents. Cross-sectional study of 784 adolescents from 10 to 14 years old (53.9% girls). Overlapping 95% confidence intervals (95%CI) were used to compare mean light (LPA), moderate (MPA), vigorous (VPA) and moderate to vigorous (MVPA) physical activity times and prevalence of sufficient PA levels between different numbers of hours ( ≥ 6, ≥ 8 and ≥ 10 hours/day) and days ( ≥ 3, ≥ 4, ≥ 5 and 7 days of use). The criterions of ≥ 6 hours/day with ≥ 3, ≥ 4, ≥ 5 e 7 days and ≥ 8 hour/day with ≥ 3, ≥ 4 e ≥ 5 days of accelerometer use underestimated, in average, the LPA time in 23.1 and 12.6 min/day, respectively, compared ≥ 10 hours/day. There were no significant differences in mean MPA, VPA and MVPA times and prevalence of sufficient PA levels between the number of hours and days of use analyzed. To produce accurate estimates of PA time in teenagers, ≥ 3 days of accelerometer use was adopted for ≥ 10 hours/day of LPA and ≥ 6 hours/day of MPA, VPA and MVPA.Resumo Objetivou-se analisar o efeito da quantidade de horas e dias de uso do aceler ômetro sobre as estimativas de tempo de atividade física (AF) em adolescentes.

CONCLUSION: Prevalence of antibiotic use was high not only versus other hospitals in the region but globally including Africa, coupled with significant evidence of sub-optimal prescribing. Swift action is needed to improve future prescribing to reduce AMR. One or two areas should initially be targeted for quality improvement including development of local guidelines, documentation of antibiotic indications and/or stop/review dates.

Authors: Rombauts A, Abelenda-Alonso G, Cuervo G, Gudiol C, Carratalà J Abstract INTRODUCTION: Despite adequate antibiotic coverage, community-acquired pneumonia (CAP) remains a leading cause of hospitalization and mortality worldwide. It induces both a local pulmonary and a systemic inflammatory response, particularly significant in severe cases. The intensity of the dysregulated host response varies from patient to patient and has a negative impact on survival and other outcomes. AREAS COVERED: This comprehensive review summarizes the pathophysiological aspects of the inflammatory response in CAP, brie...

Authors: Hammerschlag MR, Sharma R Abstract INTRODUCTION: Azithromycin was recommended as the first-line therapeutic regimen for treatment of genital infections in men and women by the Centers for Disease Control in 1998. A series of studies of azithromycin for treatment of rectal chlamydial infection in men who have sex with men (MSM) found that azithromycin was significantly less effective than doxycycline. AREAS COVERED: Literature on treatment of rectal C. trachomatis from 2000 through May 2020 was searched using PubMed. Retrospective and observational studies were identified documenting the frequency and t...

Authors: Reissier S, Cattoir V Abstract INTRODUCTION: Streptogramins (pristinamycin and quinupristin-dalfopristin) can be interesting options for the treatment of infections due to Gram-positive cocci, especially multidrug-resistant isolates. AREAS COVERED: This review provides an updated overview on structural and activity characteristics, mechanisms of action and resistance, pharmacokinetic/pharmacodynamic and clinical use of streptogramins. EXPERT OPINION: The streptogramin antibiotics act by inhibition of the bacterial protein synthesis. They are composed of two chemically distinct compounds, namely typ...
