Improvement in Physical Activity in Persons With Obstructive Sleep Apnea Treated With Continuous Positive Airway Pressure.

Background: Exercise improves sleep quality, yet people with untreated obstructive sleep apnea (OSA) may engage in less physical activity (PA) due to fatigue and daytime sleepiness. We examined changes in PA and sleep quality before and after treatment with continuous positive airway pressure (CPAP) in OSA patients.

Methods: In this prospective longitudinal study, persons with a primary diagnosis of OSA were enrolled at a community-based hospital in New York City.

Impact of Obesity on Outcomes in a Multiethnic Cohort of Medical Intensive Care Unit Patients.

Purpose: To examine the association of obesity with in-hospital mortality and complications during critical illness.

Methods: We performed a retrospective analysis of a multiethnic cohort of 699 patients admitted to medical intensive care unit between January 2010 and May 2011 at Mount Sinai St. Luke's and Mount Sinai West Hospitals, tertiary care centers in New York City.

Obstructive sleep apnea and acute respiratory failure: An analysis of mortality risk in patients with pneumonia requiring invasive mechanical ventilation.

Purpose: Although obstructive sleep apnea (OSA) is common and pneumonia is a frequent cause of acute respiratory failure requiring admission to the intensive care unit, little is known about the effect of OSA on this patient population. This study examined outcomes associated with OSA in patients with pneumonia requiring invasive mechanical ventilation.

Materials And Methods: The Nationwide Inpatient Sample was investigated for discharges with a primary diagnosis of pneumonia requiring invasive mechanical ventilation between 2009 and 2011.
