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.

COVID-19 severity is linked to changes in mitochondrial DNA methylation

This study examined mitochondrial and nuclear-encoded mitochondrial DNA methylation in Indian patients with severe COVID-19 and found region-specific differential methylation linked to disease severity. Pathway analyses and protein assays implicated disrupted mitochondrial metabolism and dynamics, suggesting a role for mitochondrial epigenetic regulation in COVID-19 pathophysiology.

Pulse oximeters miss hypoxemia more often in people with darker skin, study finds

This large prospective UK study compared five low-cost fingertip pulse oximeters with arterial blood gas measurements and found that readings varied systematically by skin tone and oxygen saturation level. Small average overestimations in darker skin translated into clinically meaningful increases in missed hypoxemia at commonly used SpO2 thresholds.

COVID-19 immunity stays specific and barely boosts protection against common cold coronaviruses

This study shows that SARS-CoV-2 infection and vaccination generate strong, highly specific spike-binding immune responses with only modest effects on immunity to endemic common cold coronaviruses. Pre-existing coronavirus immunity patterns remain largely intact, indicating that SARS-CoV-2 has integrated into the human viral landscape without broadly reshaping cross-reactive protection.

Diabetes could drain up to INT$78.8 trillion from the global economy by 2050, study finds

This global macroeconomic analysis estimates that diabetes mellitus will cost the world economy INT$10.2 trillion between 2020 and 2050, rising to INT$78.8 trillion when unpaid informal caregiving is included. Using a health-augmented economic model across 204 countries, the study shows that informal care is the dominant and most underestimated driver of diabetes-related economic losses worldwide.
