Incidence and Risk Factors of Legionella pneumophila Pneumonia During Anti-Tumor Necrosis Factor Therapy: A Prospective French Study.
Our objective was to describe the incidence and risk factors of legionellosis associated with tumor necrosis factor (TNF)-α antagonist use. ⋯ The incidence rate of legionellosis for patients receiving TNF-α antagonists is high, and the risk is higher for patients receiving anti-TNF-α monoclonal antibodies than soluble TNF-receptor therapy. In case of pneumonia occurring during TNF-α antagonist therapy, specific urine antigen detection should be performed and antibiotic therapy should cover legionellosis.

CPAP Improves Endothelial Function in Patients With Minimally Symptomatic OSA: Results From a Subset Study of the MOSAIC Trial.
Minimally symptomatic OSA is a highly prevalent disorder, and the effects of CPAP on vascular function in these patients are unknown. This trial aimed to investigate whether CPAP improves vascular function in minimally symptomatic OSA. ⋯ CPAP improves endothelial function, but not arterial stiffness, in minimally symptomatic OSA. Thus, minimally symptomatic OSA may be a cardiovascular risk factor.

Heparin-induced thrombocytopenia in medical surgical critical illness.
In a recent multicenter randomized trial comparing unfractionated heparin (UFH) with low-molecular-weight heparin (dalteparin) for thromboprophylaxis in 3,746 critically ill patients, 17 patients (0.5%) developed heparin-induced thrombocytopenia (HIT) based on serotonin-release assay-positive (SRA+) status. A trend to a lower frequency of HIT with dalteparin vs UFH was observed in the intention-to-treat analysis (five vs 12 patients, P = .14), which was statistically significant (three vs 12 patients, P = .046) in a prespecified per-protocol analysis that excluded patients with DVT at study entry. We sought to characterize HIT outcomes and to determine how dalteparin thromboprophylaxis may reduce HIT frequency in patients in the ICU. ⋯ The lower risk of HIT in patients in the ICU receiving dalteparin appears related to both decreased antibody formation and decreased clinical breakthrough of HIT among patients forming antibodies.

Epidemiology and Long-term Clinical and Biologic Risk Factors for Pneumonia in Community-Dwelling Older Americans: Analysis of Three Cohorts.
Preventing pneumonia requires better understanding of incidence, mortality, and long-term clinical and biologic risk factors, particularly in younger individuals. ⋯ Pneumonia hospitalization is common and associated with high mortality, even in younger healthy adults. Long-term risk of pneumonia can be predicted in community-dwelling adults with a simple clinical risk prediction model.

Population-Based Burden of COPD-Related Visits in the ED: Return ED Visits, Hospital Admissions, and Comorbidity Risks.
Little is known about the population-based burden of ED care for COPD. ⋯ The population-based burden of COPD-related care in the ED is significant. Further research is needed to understand variations in COPD-related ED visits and hospital admissions.
