Latest Coronavirus Disease COVID 19 News and Research

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.

Social isolation emerges as a key, independent risk factor for cognitive decline

Using longitudinal data from the US Health and Retirement Study, this study applied causal inference modeling to disentangle the independent and joint effects of social isolation and loneliness on later-life cognitive function. It shows that reducing social isolation is associated with modest but meaningful protection against cognitive decline, with loneliness mediating only a small proportion of this effect.

Metabolic syndrome affects nearly four in ten US adults as rates climb in older and Black populations

A large NHANES analysis found that nearly four in ten US adults met criteria for metabolic syndrome between 2013 and 2023, with no statistically significant change in overall prevalence. However, prevalence rose significantly among adults aged 60 years and older and among non-Hispanic Black individuals, alongside a significant non-linear increase in hypertriglyceridemia.

Why the form of vitamin B12 you take may matter more than your intake

This comprehensive review examines vitamin B12 absorption, physiological roles, deficiency states, and dietary sources, with particular attention to differences between natural and synthetic forms. The authors conclude that while all B12 forms raise circulating levels, methylcobalamin may offer advantages in specific clinical contexts, especially where absorption or metabolic conversion is impaired.

Young Australians are staying on antidepressants for longer than ever

Long-term antidepressant use in Australia increased steadily between 2014 and 2023, with the largest relative rise seen among adolescents and young adults aged 10 to 24 years. Treatment duration also lengthened over time, while apparent dose reduction efforts remained limited, raising concerns about deprescribing practices.

Poor lung gas exchange may help explain lingering brain symptoms in Long COVID

This study found that people with Long COVID more than two years after infection showed normal lung tests and brain structure, yet reported significant sleep and cognitive symptoms. Subtle correlations revealed that poorer lung gas exchange was linked with higher brain perfusion, worse sleep, and weaker executive function, suggesting a possible lung–brain connection.
