Elevated serum magnesium levels are strongly linked to higher mortality in sepsis, suggesting a critical role for magnesium in assessing sepsis risk and guiding treatment strategies.

com A recent Lancet Healthy Longevity study investigated the relationship between air pollutants and physical disability among older adults in the United States. Physical disability and exposure to ambient air pollution Physical disability is a key marker of overall health in older adults, with at least some degree of physical disability reported by about 40% of adults 65 years of age and older. Exposure to nitrogen dioxide (NO 2 ), ozone (O 3 ), and ambient particulate matter is a known risk factor for premature mortality and morbidity.
These pollutants induce inflammation and oxidative stress, associated with chronic diseases that can lead to disability later in life. It remains unclear how exposure to air pollutants impacts the clinical manifestations of physical disabilities. Most studies examining the adverse effects of air pollutants have either been conducted in high-pollution settings or focused on single-pollutant models.
There also remains a lack of studies conducted in lower-pollution settings. Furthermore, these studies are not suitable for inferring the independent effects of individual pollutants, as they often assess summary indicators.
