METHODS: A cross-sectional study was conducted on a convenience sample of 451 parents of under-six-year-old children in the western region of Saudi Arabia...

Pushes toward earlier detection of Alzheimer's disease (AD)-related cognitive changes are creating interest in leveraging technologies, like cellphones, that are already widespread and well-equipped for data collection to facilitate digital monitoring for AD. Studies are ongoing to identify and validate potential "digital biomarkers" that might indicate someone has or is at risk of developing AD dementia. Digital biomarkers for AD have potential as a tool in aiding more timely diagnosis, though more robust research is needed to support their validity and utility...

PURPOSE: We aimed to investigate the heterogeneity of synovial fibroblasts and their potential to undergo cell state transitions at the resolution of single cells. MATERIALS AND METHODS: We employed the single-cell RNA sequencing (scRNA-seq) approach to comprehensively map the cellular landscape of the shoulder synovium in individuals with chronic rotator cuff tears (RCTs) and acute proximal humerus fractures (PHFs). Utilizing unbiased clustering analysis, we successfully identified distinct subpopulations of fibroblasts within the synovial environment...

Mobile phone use while driving remains a significant traffic safety concern. Although numerous interventions have been developed to address it, there is a gap in the synthesis of relevant information through a comprehensive behaviour change lens. This scoping review uses the Behaviour Change Wheel (BCW) and the Theoretical Domains Framework (TDF) to examine the literature to (a) identify behavioural constructs targeted in interventions for mobile phone use while driving, (b) determine if the intervention success varied by sociodemographic group (e...

Dependence on smartphones continues to grow, with young adults showing the highest usage. In fact, reliance on smartphones may indicate a behavioral addiction, a concept gaining interest in both research and clinical practice. However, valid and reliable assessments of smartphone addiction are needed. To this end, we developed the Smartphone Addiction Measure (SAM) with an initial sample (113 participants; 32 males, 81 females) and assessed the validity and reliability of this new measure. Principle components analysis with an additional sample (286 participants; 78 males, 207 females, 1 other) revealed four factors generally associated with addiction, including salience, mood modification, withdrawal, and conflict, thus providing support for the SAM as a valid measure of addictive behavior related to smartphone use...

This study assessed feasibility and psychometric properties of the Hebrew parent version of the Pediatric Symptom Checklist (PSC-17), aiming to improve treatment access for children and adolescents with behavioral and mental needs through early screening. The PSC-17 and the Strengths and Difficulties Questionnaire (SDQ) were filled in the waiting room, at three ambulatory clinics in a tertiary pediatric center, by 274 parents using a tablet or their cellphone. Demographic and clinical data were retrieved from patients' files...

BACKGROUND: In tuberculosis (TB) control, nonadherence to treatment persists as a barrier. The traditional method of ensuring adherence, that is, directly observed therapy, faces significant challenges that hinder its widespread adoption. Digital adherence technologies such as video directly observed therapy (VDOT) are emerging as promising solutions. However, as these novel technologies gain momentum, a critical gap is the lack of comprehensive studies evaluating their efficacy and the unique experiences of patients in Africa...

The concept of distracted pedestrians and its impact on highway safety has gained increasing attention in recent years. However, studies focusing exclusively on distracted pedestrian crashes are less pervasive than distracted driving. In addition, most prior studies investigate the harmful effect of cellphone usage while walking, without considering other forms of pedestrian distraction. Also, the existing literature provides limited knowledge on comprehending the affinities between pedestrian distraction and safety consequences...

BACKGROUND: Routine in-person follow-up for injured patients after hospital discharge is unfeasible in low- and middle-income countries where trauma morbidity and mortality are the highest.
