Central sleep apnea (CSA) is common among patients with heart failure (HF) and is promoted by elevated CO2 chemosensitivity. Left atrial size is a marker of the hemodynamic severity of HF. The aim of this study was to determine if left atrial size predicts chemosensitivity to CO2 and CSA in patients with HF. ⋯ Increased LAVI is associated with heightened CO2 chemosensitivity and greater frequency of CSA. LAVI may be useful to guide referral for polysomnography for detection of CSA in patients with HF.

Multicenter Study
Decrease in Mortality in Severe Community-Acquired Pneumococcal Pneumonia: Impact of Improving Antibiotic Strategies (2000-2013).
The objective of the present study was to compare antibiotic prescribing practices and survival in the ICU for patients with pneumococcal severe community-acquired pneumonia (SCAP) between 2000 and 2013. ⋯ In pneumococcal SCAP, early antibiotic prescription and use of combination therapy increased. Both were associated with improved survival.

Comparative Study
Obstructive Sleep Apnea and Depression are common and independently associated with refractory angina in patients with coronary artery disease.
Refractory angina is a severe form of coronary artery disease (CAD) characterized by persistent angina despite optimal medical therapy. OSA and depression are common in patients with stable CAD and may contribute to a poor prognosis. We hypothesized that OSA and depression are more common and more severe in patients with refractory angina than in patients with stable CAD. ⋯ OSA and depression are independently associated with refractory angina and may contribute to poor cardiovascular outcome.

Changes in medical practice, such as retiring, selling a practice, and switching employment, have significant legal impacts on physicians. These decisions should be carefully analyzed prior to being made. Physicians who do not make decisions in a well-considered manner may face economic penalties, licensure sanctions, and/or other legal issues. ⋯ Within these topics, sources of physicians' legal and ethical obligations are examined, including possible resolutions to identified issues. Not all changes affect physicians in the same manner. This article further considers how these important legal issues may impact differently situated physicians, such as retiring physicians vs transitioning physicians and physicians employed by groups or hospital systems vs physicians in solo practice.
