Positron emission tomography (PET) data were obtained from subjects performing a synchronization task (target duration 2700 ms). A conjunction analysis was run to identify areas prominently activated both in this task and in a temporal generalization task (target duration 700 ms) used previously. The common pattern of activation included the right prefrontal, inferior parietal and anterior cingulate cortex, the left putamen and the left cerebellar hemisphere. These areas are assumed to play a major role in time processing, in relation to attention and memory mechanisms.

Exploring Virtual Reality and Exercise Simulator Interventions in Patients With Attention Deficit Hyperactivity Disorder: Comprehensive Literature Review.
JMIR Serious Games
January 2025
School of Computing, Engineering and Mathematical Sciences, Optus Chair Digital Health, La Trobe University, Melbourne, Australia.
Background: This review explores virtual reality (VR) and exercise simulator-based interventions for individuals with attention-deficit/hyperactivity disorder (ADHD). Past research indicates that both VR and simulator-based interventions enhance cognitive functions, such as executive function and memory, though their impacts on attention vary.
Objective: This study aimed to contribute to the ongoing scientific discourse on integrating technology-driven interventions into the management and evaluation of ADHD.
The Promotion of Oral Nicotine Pouches for Non-Smoking Cessation Purposes on TikTok.
Nicotine Tob Res

Faculty of Public Health & Policy, London School of Hygiene and Tropical Medicine, Keppel St, London WC1E 7HT, United Kingdom.
Introduction: Oral nicotine pouches (ONPs) are increasingly prevalent among young people and feature widely within social media content. This study systematically analyzes the most viewed videos on TikTok relating to ZYN (the most popular ONP, manufactured by a subsidiary of Philip Morris International) to understand their content sentiment and patterns, as well as the demographics and potential commercial biases of their creators.
Methods: We used an Apify scraper in July 2024 to collect URLs and metadata for the top 100 most viewed videos on TikTok under the #ZYN hashtag.
Longitudinal Analysis of Obesity Drug Use and Public Awareness.
JAMA Netw Open
January 2025
Johns Hopkins Ciccarone Center for the Prevention of Cardiovascular Disease, Johns Hopkins University School of Medicine, Baltimore, Maryland.
Importance: Obesity, a chronic disease with escalating global prevalence, poses considerable health risks. Glucagon-like peptide 1 receptor agonists (GLP-1RAs), including liraglutide, semaglutide, and tirzepatide, have demonstrated efficacy for weight loss in clinical trials. The paradigm shift in the approach to obesity management drugs (OMDs) may offer an opportunity to examine online search activity and prescription trends.

Objective: To determine the effectiveness of health system-based, community-based dementia care, and usual care for persons with dementia and for caregiver outcomes.
Design, Setting, And Participants: Randomized clinical trial of community-dwelling persons living with dementia and their caregivers conducted at 4 sites in the US (enrollment June 2019-January 2023; final follow-up, August 2023).
Stair-descent phenotypes in community-dwelling older adults determined using high-level balance tasks.
Aging Clin Exp Res
January 2025
Department of Physical Medicine and Rehabilitation, Kansai Medical University, Osaka, Japan.
Background: Falls on stairs are a major cause of severe injuries among older adults, with stair descent posing significantly greater risks than ascent. Variations in stair descent phenotypes may reflect differences in physical function and biomechanical stability, and their identification may prevent falls.
Aims: This study aims to classify stair descent phenotypes in older adults and investigate the biomechanical and physical functional differences between these phenotypes using hierarchical cluster analysis.
