Digital vaccination campaigns are increasingly used to address declining vaccine confidence, yet evidence from large-scale, real-world interventions in middle-income countries is limited. Meta’s Brand Lift Studies (BLS), which use randomized test–control exposure, provide Bayesian esti-mates of attitudinal shifts resulting from digital content. Mexico, with over 88.6 million active internet users, provides a setting to evaluate the impact of targeted campaigns on vaccine atti-tudes.

Biomedical research studies are increasingly using digital to enroll, recruit and collect data from participants. However, variability in digital literacy and technological acceptance can be challenging for recruitment from groups traditionally underrepresented in research, including those served by Federally Qualified Health Centers.

Although sexual exploration is normative during adolescence, sexual activities that are unprotected and occur under the influence of substances can pose significant risks to young people. Youth exposed to adversity are among the groups most vulnerable to sexual risk-taking in adolescence. Selective interventions that consider lived experiences and the local context may help reduce sexual risk-taking among this population.

This study demonstrates that GPT-4o outperforms traditional natural language processing methods in accurately analyzing patient sentiment toward atopic dermatitis treatments on Reddit, enabling more nuanced and reliable extraction of real-world patient perspectives from large-scale social media data.

Cardiovascular diseases (CVDs) remain the leading global cause of mortality, yet traditional electrocardiogram (ECG) interpretation suffers from subjective variability and limited sensitivity to complex pathologies.

In 2020, the global prevalence of overweight and obesity was approximately 42%. One of the most common associated conditions is type 2 diabetes mellitus, which had a global prevalence of around 10.5% in 2021. Digital health applications (DiHA), which can be prescribed as certified medical devices in Germany, have been shown to effectively support disease management in patients with overweight and diabetes mellitus. However, little is known about DiHA-prescribing behavior of health care providers (HCPs) specializing in hormones and metabolism or about potential barriers to prescribing these applications.

Long COVID encompasses a range of health problems that can be highly debilitating. While some research has relied on self-reported measures of symptoms and functioning, few studies have characterized symptoms in relation to behaviors and physiology measured objectively through wearable devices.

Topical steroid withdrawal (TSW) is a controversial skin condition among healthcare providers due to lack of evidence, but it has an impactful and growing presence on social media. There are few previous reports of healthcare utilisation for symptoms attributed to TSW.

Enhancing care coordination and sharing information in cancer care improves patient experiences by promoting clarity and satisfaction.

Health care professionals must stay updated with the latest guidelines for basic life support (BLS) and advanced cardiac life support (ACLS) to effectively assist patients during cardiac emergencies. Since its launch in 2018, the Ghana Heart Initiative has significantly enhanced the skills and knowledge of health care professionals in managing cardiovascular diseases, including cardiac emergencies.

There is a gap in mental health care among Latino/x and Spanish speaking communities and the care that is available is often difficult to access, lacks cultural nuance, and results in low engagement and satisfaction.

Proactive telecare offers services designed to reduce the occurrence of emergency situations by delivering proactive outbound calls, follow-ups, and providing information and advice. By engaging regularly with users, proactive telecare may foster social connections with older adults and enable the detection of changes in needs. Telecare systems that promote active participation among older adults may also foster feelings of autonomy and self-management. However, more research in this area is needed.
