Article Synopsis
  • The study examines government efforts to promote physical activity (PA) both before and during the COVID-19 pandemic, highlighting its impact on PA policies worldwide.
  • Surveys from 2023 included responses from 105 participants across 61 countries, revealing that while 82% had national PA policies, COVID-19 significantly disrupted their implementation, with less than 40% integrating PA into their pandemic responses.
  • The findings emphasize the need to prioritize PA in public health agendas post-pandemic, focusing on resource allocation, partnerships, and addressing participation inequities, which are vital for effective policy moving forward.

Background: Secondary schools are important settings for promoting varied physical activity (PA) opportunities for adolescents to promote PA throughout life. However, research on the effect of secondary school-based interventions on future PA is limited. This study examined the potential impact of secondary school-based interventions on the determinants of future PA participation of Aotearoa New Zealand (NZ) adolescents using simulated modelling.

Article Synopsis
  • Acute traumatic coagulopathy (ATC) occurs shortly after injury and is associated with higher risks of massive transfusion and mortality in trauma patients.
  • A machine learning-based Coagulation Risk Index (CRI) was developed to predict ATC using continuous vital signs recorded during the first 15 minutes after a patient’s admission to a trauma center.
  • The CRI showed high accuracy in predicting ATC, achieving true positive rates of over 90% for different levels of international normalized ratio (INR), indicating its effectiveness for early identification of coagulopathy in bleeding trauma patients.

Introduction: Global surveillance of physical activity (PA) of children and adolescents with questionnaires is limited by the use of instruments developed in high-income countries (HICs) lacking sociocultural adaptation, especially in low- and middle-income countries (LMICs); under-representation of some PA domains; and omission of active play, an important source of PA. Addressing these limitations would help improve international comparisons, and facilitate the cross-fertilisation of ideas to promote PA. We aim to develop and assess the reliability and validity of the app-based Global Adolescent and Child Physical Activity Questionnaire (GAC-PAQ) among 8-17 years old in 14 LMICs and HICs representing all continents; and generate the 'first available data' on active play in most participating countries.

Background: Implementation science seeks to systematically identify determinants, strategies, and outcomes within a causal pathway to help explain successful implementation. This process is applied to evidence-based interventions (EBIs) to improve their adoption, implementation, and sustainment. However, this method has not been applied to exercise oncology services, meaning we lack knowledge about implementing exercise EBIs in routine practice.

Objective: Physical activity (PA) interventions are part of many interdisciplinary programs for the management of children and adolescents with or without physical or psychological conditions or disabilities. Aiming to summarize the available evidence, we conducted an umbrella review of meta-analyses of PA interventions that included psychosocial outcomes in populations of children and adolescents.

Method: Literature searches were conducted in PubMed, Cochrane Central, Web of Science, Medline, SPORTDiscus, and PsychInfo from January 1, 2010, to May 6, 2022.
