Self-Reported Sleep Duration Is a Useful Tool to Predict Sarcopenia in Chilean Older Adults: Evidence from the ALEXANDROS Longitudinal Study.

Age-related sleep disorders share common pathways with sarcopenia. Prospective data from Latin American populations are scarce, and the association between sleep disorders and sarcopenia in Chileans remains unknown. Thus, we aimed to study the longitudinal association between sleep disorders and sarcopenia in a cohort study of 1116 community-dwelling Chilean older people ≥60 years old from the ALEXANDROS cohorts.

[Implementation of a virtual telehealth course for Chilean older adults and health students].

Background: Aging increases the vulnerability to diseases and environmental changes such as the COVID-19 pandemic. Telehealth and tele-education are vital to prevent the deleterious effects of prolonged confinement, and to train the community, and constantly rotating medical students and health professionals.

Aim: To assess the perception and impact of an online course about healthy aging aimed at the community and health care professionals.

Latin American Initiative for Lifestyle Intervention to Prevent Cognitive Decline (LatAm-FINGERS): Study design and harmonization.

Introduction: Latin American Initiative for Lifestyle Intervention to Prevent Cognitive Decline (LatAm-FINGERS) is the first non-pharmacological multicenter randomized clinical trial (RCT) to prevent cognitive impairment in Latin America (LA). Our aim is to present the study design and discuss the strategies used for multicultural harmonization.

Methods: This 1-year RCT (working on a 1-year extension) investigates the feasibility of a multi-domain lifestyle intervention in LA and the efficacy of the intervention, primarily on cognitive function.

Dual-Task Gait as a Predictive Tool for Cognitive Impairment in Older Adults: A Systematic Review.

The use of the dual-task model as a cognitive-motor interface has been extensively investigated in cross-sectional studies as a training task in cognitive impairment. However, few existing longitudinal studies prove the usefulness of this tool as a clinical marker of cognitive impairment in older people. What is the evidence in prospective studies about dual-task gait as a predictor of cognitive impairment in older adults? This study aims to review and discuss the current state of knowledge in prospective studies on the use of dual-task gait as a predictive tool for cognitive impairment in older adults.

No effect of mercury exposure on kidney function during ongoing artisanal gold mining activities in Colombia.

This cross-sectional study examined whether people who are exposed to mercury (Hg) vapours in ongoing artisanal gold mining activities have alteration in kidney function monitoring parameters. The study enrolled 164 miners and 127 participant controls. The Hg concentrations for miners and control participants were measured in blood (B-Hg; median 7.

[Clinical manifestations of lead levels in children exposed to automobile battery recycling processes in Soacha and Bogotá, D.C].

Introduction: Lead is a harmless metal if not handled directly in the industrial process. Even thought lead has been eliminated from the gasoline in many countries, automobile battery recycling continues to be a potential source of exposure and intoxication for the workers and their families, particularly of low income. The current investigation was initiated after an index case of lead poisoning was reported from Soacha, Cundinamarca, in central Colombia.
