This systematic review and meta-analysis assessed whether household exposure to biomass smoke is associated with COPD in women. The investigators synthesized epidemiologic studies from different regions and found an overall association between biomass exposure and COPD, with a particularly clear relationship in studies of chronic bronchitis and in both rural and urban populations. The work is especially relevant to respiratory practice in settings where cooking with solid fuels remains common and where women may experience prolonged household exposure. The study reinforces that smoking history alone does not capture all clinically relevant inhalational risk. For pulmonologists, a careful environmental history should include cooking fuels, ventilation, occupational exposures and the duration of household exposure. The paper fits closely with the NAPCON COPD symposium's focus on biomass smoke, air pollution and the distinct burden faced by Indian patients. It also supports a practical counseling message: exposure reduction is part of respiratory risk management, not simply a public-health footnote. Because the evidence is primarily observational, the association should not be interpreted as proof of causation in every individual case, but it is strong enough to justify routine consideration of biomass exposure when evaluating COPD—particularly in women who have never smoked.

Preclinical findings demonstrate that ginsenoside Ra1 preserves vascular integrity and attenuates multi-organ injury during sepsis by targeting non-muscle myosin heavy chain IIA (NMMHC IIA) and dampening TLR4/NF-κB/NLRP3 inflammatory signaling.

Recent research defines ferro-aging as a conserved iron-lipid axis driving organ decline across primates. Age-related iron dyshomeostasis stimulates ACSL4-mediated lipid peroxidation, promoting cellular senescence. Notably, vitamin C directly inhibits ACSL4, suppressing phospholipid oxidation and multi-organ decay.
