Objective: The World Health Organization (WHO) Southeast Asian region, comprising a quarter of the global population, faces significant healthcare challenges influenced by diverse economic and social conditions. The objective of this study is to map the Digital Health Intervention (DHI) functionalities across the nine axes of the healthcare system challenges (HSCs) model; we use WHO's DHIs classification framework and the Health System Challenges model. Our study findings help identify the gaps in the potential of the existing DHIs in addressing health system challenges in low- and middle-income countries.

Introduction: Urgency has been defined as the tendency towards rash speech and behavior in the context of emotion. Measures of Urgency have been found to have robust predictive power for psychopathologies and problematic behaviors. In the current study, we question whether emotions are unique drivers of urgency, or if emotions are potent exemplars of contexts that lead to rash speech and behavior.

Article Synopsis
  • Exposure to repetitive head impacts (RHI) correlates with chronic traumatic encephalopathy (CTE), which can only be diagnosed after death; the study explores the presence of a cavum septum pellucidum (CSP) in living former football players to understand its relation to RHI and potential CTE.
  • The research involved 175 former players, both college and professional, and compared their CSP measurements to a control group without RHI exposure, assessing associations with cumulative head impact and traumatic encephalopathy syndrome (TES).
  • Results indicated that former players had significantly higher CSP presence and ratio compared to controls, with professional players exhibiting an even greater ratio; however, there was no notable link between CSP and TES or provisional

Previous work suggests that sometimes the more people value happiness, the less happy they are. For whom and why is this the case? To answer these questions, we examined a model of happiness pursuit that disentangles two previously conflated individual differences related to valuing happiness. The first individual difference operates at the strength of the value itself and involves viewing happiness as a very important goal (i.

  • The Human Connectome Project for Early Psychosis (HCP-EP) studies how the brain works in people who are starting to experience psychosis, which is when someone has trouble telling what's real and what's not.
  • They collected detailed information from 303 participants aged 16-35 across different hospitals in Massachusetts and Indiana.
  • The study aims to help researchers understand and compare different types of psychosis, and all the data is available for other scientists to use.

Telemedicine is a promising solution to the challenges of delivering equitable and quality primary healthcare, especially in LMICs. This review evaluated peer-reviewed literature on telehealth interventions in Indian primary care published from Jan 1, 2011 to Dec 31, 2021, from PubMed, Scopus, TRIP, Google Scholar, Indian Kanoon, and Cochrane database The majority of Indian studies focus on key health issues like maternal and child health, mental health, diabetes, infectious diseases, and hypertension, mainly through patient education, monitoring, and diagnostics. Yet, there's a lack of research on telemedicine's cost-effectiveness, communication among providers, and the role of leadership in its quality and accessibility.

Attention-deficit/hyperactivity disorder (ADHD) is a childhood-onset neurodevelopmental condition characterized by developmentally extreme and impairing symptoms of inattention and/or hyperactivity/impulsivity. Great interest has emerged in the ways ADHD and its underlying symptom dimensions relate to the development of personality traits. Much extant research on this topic is cross-sectional, relying on self-report measures and male samples.

This article provides a nuanced exploration of the state and exigencies of neurosurgical training in sub-Saharan Africa (SSA), viewed through the discerning lens of a medical student. The region has a pronounced scarcity of neurosurgical services, further compounded by sociocultural intricacies and infrastructural inadequacies, resulting in elevated mortality and morbidity rates. The insufficiency of neurosurgeons, facilities, and training centers, particularly in remote areas, exacerbates this predicament.

Article Synopsis
  • A study examined the effects of vitamin D3, omega-3s, and a home-based exercise program (SHEP) on bone mineral density (BMD) in healthy older adults aged 70 and above over three years.
  • Results showed no significant benefits from omega-3s or SHEP, but vitamin D3 improved total hip BMD and lumbar spine BMD in men with modest gains.
  • While there were some positive effects of vitamin D treatment, the overall clinical significance of these findings remains uncertain.

Article Synopsis
  • * A study evaluated brain structures using MRI in 170 former football players and 54 controls, assessing regions associated with CTE pathology, revealing significant reductions in cortical thickness and volume in players compared to controls.
  • * Former professional players showed more pronounced brain changes than former college players, specifically in areas like the hippocampus and amygdala, indicating that exposure to head impacts has lasting effects on brain structure.

This article describes the rationale, aims, and methodology of the Accelerating Medicines Partnership® Schizophrenia (AMP® SCZ). This is the largest international collaboration to date that will develop algorithms to predict trajectories and outcomes of individuals at clinical high risk (CHR) for psychosis and to advance the development and use of novel pharmacological interventions for CHR individuals. We present a description of the participating research networks and the data processing analysis and coordination center, their processes for data harmonization across 43 sites from 13 participating countries (recruitment across North America, Australia, Europe, Asia, and South America), data flow and quality assessment processes, data analyses, and the transfer of data to the National Institute of Mental Health (NIMH) Data Archive (NDA) for use by the research community.

Telehealth in India is growing rapidly and represents a strategy to promote affordable, inclusive, timely and safe access to healthcare. Yet there is a risk that telehealth increases inequity due to the digital divide and existing poor health literacy. A scoping review was conducted to explore use of telehealth in India during and following the COVID-19 pandemic by people with disabilities to inform strategies to increase equity of telehealth for people with disabilities.

BACKGROUND: Optimal thromboprophylaxis for hospitalized patients with coronavirus disease 2019 (Covid-19) is uncertain. METHODS: In an open-label, adaptive platform trial, we randomly assigned hospitalized adults with Covid-19 to low-dose low-molecular-weight heparin thromboprophylaxis or intermediate-dose or low-dose plus aspirin. In response to external evidence, the aspirin intervention was discontinued and a therapeutic-dose arm added.

Objectives: The assessment of personality traits is most often based on self-report. However, a growing body of research has shown that informant-report is a valuable and too often overlooked source of unique information. The aim of this study was to validate the French version of the informant-report form of the Big Five Inventory-2 (BFI-2) which assesses 15 facet traits in addition to the five major trait domains.
