Research at Yale School of Medicine shows that patients are at high risk of readmission for a broad spectrum of medical conditions within the first month after hospital discharge. The study found that readmissions were frequent and resulted from different medical conditions than the initial hospitalization.
A meta-analysis found that current smokers with HIV were at double the risk of bacterial pneumonia than non-smokers, but stopping smoking decreased this risk by about a third. Stopping smoking reduced the risk of bacterial pneumonia by approximately 30-70% compared to non-smoking counterparts.
Researchers have sequenced the genome of Pneumocystis jirovecii, a fungus that causes pneumocystis pneumonia, a common and often deadly infection in immunocompromised individuals. The genome reveals surprising facts about the pathogen's survival and virulence.

Patients given amoxicillin did not recover much quicker or have significantly fewer symptoms, and the treatment appeared to have a limited effect even in older patients.
A year-long study found that ceramic cookstoves in rural Kenya reduced air pollution but had no significant impact on pneumonia rates among young children. Despite lower smoke levels and respiratory symptoms, the stoves did not demonstrate a substantial health benefit.
Researchers found point-of-care ultrasound to be highly specific (97%) and sensitive (92%) for diagnosing pneumonia, outperforming the traditional method of auscultation by stethoscope. Ultrasound can also detect small pneumonias that a chest x-ray may miss, making it a valuable tool in pediatric care.

A new strategy is used to determine if observational studies have unmeasured factors, finding that PPIs may not increase the risk of pneumonia. The study suggests that patient or provider characteristics, rather than medication use, are driving these associations.
A study found sharp increases in heart failure and pneumonia following the Japanese earthquake, while stroke and cardio-pulmonary arrest rates followed seismic peaks. Blood pressure was also elevated, but medication disruptions may have contributed to cardiovascular events.
A new study found that pneumonia and preterm birth complications are leading causes of childhood death, accounting for 64% of deaths globally. Despite a decline in total deaths between 2000 and 2010, the reduction is not sufficient to meet the Millennium Development Goal of reducing child mortality by two-thirds by 2015.
Recent studies suggest a decline in pneumonia hospitalizations and inpatient deaths in the US. However, analysis of data from the Nationwide Inpatient Sample reveals that trends in diagnostic coding, such as increased use of sepsis and respiratory failure codes, may be driving these declines.
