A recent study found that vitamin E supplements increased pneumonia risk by 68% in older smoking men who didn't exercise, while decreasing risk by 69% in those who exercised regularly. The findings suggest that a single universal estimate of vitamin E's effect may be misleading for some population groups.
Rates of childhood pneumonia vary globally with solid fuel use; efficient stoves can reduce indoor pollution and improve child health. Improved cooking fuels may significantly benefit children's health worldwide.

The materials, which include molecules such as PAMAM, exhibit greater efficacy against certain strains of E. coli and Klebsiella pneumoniae, and may also enhance the effectiveness of existing antibiotics.
A study found that a better nurse work environment can increase VAP risk, while a closed physician staffing model is not significantly associated with lower VAP risk. The interaction between the two factors reveals a complex relationship where better work environments may minimize VAP in open ICUs but increase it in closed ICUs.
A study found that Veterans Affairs (VA) hospitals had lower 30-day all-cause mortality rates for heart attack and heart failure, but higher readmission rates for these conditions compared to non-VA hospitals. The findings suggest that VA hospitals are starting from a better place in terms of quality care than two decades ago.

Research findings suggest that intensive care units (ICUs) may be beneficial for older adults with pneumonia, with a nearly 6% improvement in survival associated with ICU admission. The costs to Medicare and hospitals were the same for both groups, despite the ICU's reputation as a high-cost place to care for patients.
A study of Medicare beneficiaries found that older patients with pneumonia who were admitted to the ICU had lower mortality rates compared to those admitted to general wards. The study also showed no significant differences in Medicare spending or hospital costs between the two groups.
A study found that cases flagged by 3M as preventable received no worse care than unflagged cases, suggesting that the measure may not accurately capture quality of care. The researchers concluded that either PPR flagged cases are not more preventable or that assessment requires other data collection methods.
