Consistent home-based care reduces urgent care use and hospitalizations in older adults

This study examined whether continuity of care (how often patients see their assigned physician and nurse) was associated with urgent care use and hospital admissions among older adults receiving permanent home-based primary care.

Study identifies genes, smoking, and obesity as pneumonia risk factors

Researchers at the University of Oulu have identified genes that increase susceptibility to pneumonia. Alongside inherited risk factors, smoking and higher body mass were also found to raise the risk of developing the disease.

Olive oil type matters for cognition and gut health in older adults

Higher intake of virgin and total olive oil was associated with modest but significant improvements in cognitive performance over two years in older adults with metabolic syndrome. These associations were partly linked to gut microbiota composition, with specific taxa such as Adlercreutzia contributing a small mediating effect.

Tiny plastic particles may interfere with brain processes implicated in Parkinson’s disease

Micro- and nanoplastics are increasingly detected in human tissues, including the brain, and experimental evidence suggests they can interact with biological pathways central to Parkinson’s disease pathology. This review synthesises mechanistic data indicating that plastic particles may influence protein aggregation, neuroinflammation, mitochondrial dysfunction, and the gut–brain axis, while emphasising the need for prospective human studies.

Three daily servings of full-fat dairy do not worsen weight or blood markers

This randomized 12-week trial examined whether adding three daily servings of full-fat dairy to diets aligned with Canada’s Food Guide affects body weight, cardiometabolic markers, and nutrient intake in adults with overweight or obesity. Full-fat dairy intake did not adversely affect weight, body composition, or metabolic health and increased calcium and protein intake, supporting dietary compatibility rather than therapeutic benefit.

New role for GLP-1 drugs: Improving survival in people with severe psychiatric disorders

This editorial argues that GLP-1 receptor agonists could substantially improve healthspan and reduce premature mortality in people with serious mental illnesses by targeting cardiometabolic risk rather than psychiatric symptoms alone. It highlights emerging evidence, safety considerations, and equity challenges that position GLP-1 RAs as a promising public health strategy for this high-risk population.
