A Nordic ageing cohort doubles down on nutrition, frailty, and brain health
This cohort profile update describes HUNT4 70+, an ongoing population study focused on older adults, with emphasis on ageing-related outcomes such as frailty, cognitive impairment and dementia, and linked measures including nutrition status (including malnutrition and oral health). The update signals expanded or refreshed data resources relevant to late-life health, positioning nutrition-related indicators alongside biomarkers and geriatric syndromes to support analyses of risk trajectories in advanced age.
Why it might matter to you:
Cohorts with detailed late-life nutrition and functional measures can sharpen causal questions about whether nutritional status is an early warning signal, a mediator, or a consequence of frailty and cognitive decline. You could use the cohort’s design and measurement choices to benchmark what to capture in surveillance or to inform models that connect diet-related risk to downstream health and care needs.

This JAMA Forum piece reviews health threats and downstream consequences affecting medically underserved communities along the US–Mexico border, while outlining opportunities for policy and programmatic responses. It frames the region as both uniquely exposed to compounding risks and uniquely positioned for cross-jurisdiction solutions that could improve population well-being.

It frames the region as both uniquely exposed to compounding risks and uniquely positioned for cross-jurisdiction solutions that could improve population well-being.
Why it might matter to you:
Place-based public health policy can strongly shape access to healthy food, preventive services, and safety-net programs—especially in regions where infrastructure and governance are fragmented. The discussion can help you identify where better measurement (and better policy design) could reduce inequities that standard national averages may conceal.
When the web sells what regulators forbid: the e-cigarette supply chain goes third-party
This article examines how third-party e-commerce technologies can facilitate illegal online sales of e-cigarettes. By focusing on the role of the digital commerce ecosystem—rather than only on individual sellers—it highlights how tools and intermediaries may enable restricted products to reach consumers despite existing rules.
Why it might matter to you:
Public health interventions increasingly hinge on how commercial platforms structure access, pricing, and friction—mechanisms that also matter for food environments and consumer behavior. This perspective can inform how you think about policy levers aimed at upstream “enablers” (payment, marketing, fulfillment) rather than relying solely on downstream education or enforcement.
