Digital lifestyle interventions hold promise in supporting healthy gestational weight gain (GWG) during pregnancy. However, clarity on their key design and implementation features remains limited. The prevalence of excessive GWG and its associated maternal and infant health risks makes understanding the landscape of digital intervention characteristics critical.

In the digital era, mobile internet integration into daily routines presents a paradoxical relationship with mental health outcomes. While prior cross-sectional studies report inconsistent associations between mobile internet use (MIU) and depressive symptoms, the longitudinal mechanisms involving social support remain underexplored.

Proactive integrated virtual health care resource (VHR) use is the self-initiated, coordinated use of applicable virtual systems as a team or an individual for coordinating timely delivery of high-quality health care. Based on literature and the purpose of this project, super users are defined as clinical team members identified by colleagues as proactive users of VHRs (ie, early adopters) who coordinate care delivery and champion resource use. Super users’ proactive integrated VHR use improves workflow and workload efficiency and supports provider uptake and promotion, which increases patient adoption and sustained use to improve care outcomes. Previous studies have not examined super users’ integrated use of available VHRs across the health care continuum or within service-specific clinical workflows.

In recent years, large language models (LLMs) have experienced rapid development. LLM-based virtual patients have begun to gain attention, offering new opportunities for simulations in medical education.

Individuals with substance use problems experience stigma in different contexts. Identifying characteristic situations in which stigma occurs or manifests—stigma phenotypes—can serve as important leverage points for future intervention.

Dietary behaviors are directly linked to health and well-being. Food literacy education may improve poor dietary behaviors and thus, health and well-being. Social media is a popular source of food literacy education through content delivered by influencers and experts alike. Characterizing food and nutrition content on social media using a food literacy framework can identify gaps in public food literacy knowledge and opportunities for improving food literacy education.

Low-income populations in Malaysia face significant barriers to cardiovascular disease (CVD) prevention, including limited access to health information, preventive services, and ongoing support for behavior change. Digital health technologies present scalable opportunities for promoting heart-healthy behaviors, especially when integrated with community-based peer support.

We demonstrate the feasibility of a wearable, augmented reality–based nystagmus examination system, showing its preliminary diagnostic agreement with conventional video-oculography and its potential for portable vestibular assessment in patients with vertigo.

Underserved pregnant women have a greater risk of excessive or inadequate gestational weight gain (GWG) and adverse perinatal outcomes. In the United States, the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) provides supplemental nutrition and is uniquely positioned to deliver equitable interventions that support recommended GWG. Yet to date, no randomized controlled trials have evaluated behavioral strategies for managing GWG in this setting.

Technology use is increasingly integrated into daily life, including among older adults, whose adoption and engagement with technology warrant closer examination. According to the matching person and technology model, technology adoption is more likely when a person’s preferences and needs align with a device’s functions and features, as well as the environment in which it is used. However, factors such as age-related changes, evolving preferences, and the rapid pace of digital transformation complicate this process. Additionally, older adults often rely on support from family members and health professionals, yet their perspectives remain largely unexplored.

Virtual healthcare models that incorporate registered nurse triage with rapid access to same-day virtual visits with clinicians represent a growing innovation in healthcare delivery. While traditional telephone advice lines focus primarily on RN-led triage and care navigation, systems such as the Department of Veterans Affairs (VA) are beginning to embed physicians and advanced practice providers directly into these platforms. This hybrid model has potential to enhance clinical responsiveness, reduce unnecessary emergency department and urgent care visits, and increase patient satisfaction by providing timely care from home.

Social determinants of health (SDOH) strongly influence clinical outcomes. Social needs are the individual-level, actionable facets of the broader SDOH framework, including food security, stable housing, and access to essential services. When these needs go unmet, they adversely affect wellbeing and quality of care. Systematically detecting social needs is therefore critical, and emerging digital tools now offer efficient, scalable approaches for screening and identification.
