Alzheimers Dement

Universidad de Antioquia, Medellín, Antioquia, Colombia.
Background: Dementia has a worldwide prevalence of 55 million people, with 60 to 70% of cases attributed to Alzheimer's Disease (AD). In Antioquia, Colombia, exists a group of families with early-onset AD associated to PSEN1-E280A, a genetic variant with an autosomal dominant inheritance pattern and a penetrance over 99%, which enables the study of individuals across different disease stages. Electroencephalography (EEG) is a non-invasive, portable, and low-cost technique that allows the study of electrophysiological changes associated with neurodegeneration.

January 2025
RAND Corporation, Santa Monica, CA, United States of America.
Background: Accelerometers are widely adopted for physical activity (PA) measurement. Accelerometry data require pre-processing before entering formal statistical analyses. Many pre-processing criteria may influence PA outcomes and the processed sample, impacting results in subsequent statistical analyses.

Introduction: Maternal position plays an essential role in achieving labour progress as it supports the physiological mechanisms of labour. Evidence supports that adopting upright positions may facilitate physiological childbirth.
Aim: To describe the use of various positionsamong nulliparous pregnant women in the last 24 h before birth and describe physical positions in relation to maternal and neonatal outcomes at time of birth.
The Association between Movement Behaviours and Mental Health Issues in Adolescents with Neurodevelopmental Disorders.
Med Sci Sports Exerc
December 2024
Department of Sports Science and Physical Education, The Chinese University of Hong Kong, CHINA.
Purpose: To examine movement behaviour with stress-related biomarkers alongside self-reported mental health issues in adolescents with Neurodevelopmental disorders.
Methods: One hundred fifty-one adolescents with clinically diagnosed NDD and aged between 12-17 years were recruited in Hong Kong secondary schools. Salivary cortisol as a stress-related biomarker and self-reported mental health variables including anxiety, depression, and stress were collected.
Associations of perceived neighbourhood and home environments with sedentary behaviour among adolescents in 14 countries: the IPEN adolescent cross sectional observational study.

November 2024
Mary MacKillop Institute for Health Research, Australian Catholic University, Melbourne, Australia.
Background: Understanding environmental correlates of sedentary behaviour (SB) among young people is important as such data can identify approaches to limit sedentary time. This paper estimates associations of parent-reported neighbourhood and adolescent-reported home environments with SB among adolescents aged 11-19 years from 14 countries.
Methods: In the International Physical activity and the Environment Network (IPEN) Adolescent Study (an observational, cross-sectional multi-country study), adolescents wore a triaxial accelerometer for seven days that assessed sedentary time (ST).
