OBJECTIVE Current levels of ambient air pollution are associated with morbidity and mortality in the general population. To determine the influence of gaseous air pollutants on neonatal respiratory morbidity, we tested the association between daily respiratory hospitalizations and daily concentrations of ambient air pollution gases: ozone, carbon monoxide, sulfur dioxide, and nitrogen dioxide, ...

CONTEXT Postpartum psychosis occurs in 1 to 2 cases per 1000 live births. Most studies have not distinguished postpartum psychosis from bipolar disorder or the proportion of the incidence attributable to prepregnancy psychiatric morbidity. OBJECTIVE To determine the incidence of postpartum psychosis and bipolar disorder attributable to previous psychiatric hospitalization. DESIGN Population...

BACKGROUND Acute exacerbations (AEs) have a negative impact on various aspects of the progression of COPD, but objective and detailed data on the impact of hospitalizations for an AE on physical activity are not available. Objective and measurements: We aimed to investigate physical activity using an activity monitor (DynaPort; McRoberts; the Hague, the Netherlands), pulmonary function, muscle ...

INTRODUCTION Few literatures have studied the blood management in patients treated with staged bilateral primary total knee arthroplasty (TKA) in a single hospitalization period. Therefore, this study aims to evaluate the effectiveness and safety of the newly introduced multimodal blood management (MBM) in these patients. MATERIALS AND METHODS We retrospectively compared the perioperative par...

INTRODUCTION New treatments for acute ischemic stroke (AIS) have been introduced and are expected to improve patients' overall outcomes. We assessed the impact of new therapeutic strategies on outcome and cost of hospitalization among adult patients with AIS in the United States. METHODS Patients with AIS admitted in the United States in 1993-1994 and 2006-2007 were listed using the Nationwid...

BACKGROUND Treatment of acute heart failure in the emergency department (ED) or observation unit is an alternative to hospitalization. Both ED management and observation unit management have been associated with reduced costs and may be used to avoid penalties related to rehospitalizations. The purpose of this study was to examine trends in ED visits for heart failure and disposition following ...

BACKGROUND The impact of air pollution on asthma in children in different age group has not been well defined. OBJECTIVE This study aimed to evaluate the association between seasonal variations in air pollution and asthma hospitalization of children within a two-year period. METHODS Using the National Health Insurance database, seasonal variations in hospitalization trends in children with ...

INTRODUCTION Patients with rheumatoid arthritis (RA) have an increased risk of infection and this risk appears to be higher with anti-TNF (tumor necrosis factor) agents. We pooled data from the cumulative abatacept RA clinical development program, both double-blind and open-label periods, to estimate the incidence rates (IRs) of infections requiring hospitalization including pneumonia and oppor...
