INTRODUCTION We previously derived and validated the AIMS65 score, a mortality prognostic scale for upper GI bleeding (UGIB). OBJECTIVE To validate the AIMS65 score in a different patient population and compare it with the Glasgow-Blatchford risk score (GBRS). DESIGN Retrospective cohort study. PATIENTS Adults with a primary diagnosis of UGIB. MAIN(More)
OBJECTIVE In the hospital setting, several studies have reported proton pump inhibitor (PPI) overuse, a majority of which is continued after discharge. In addition to being expensive, PPIs are associated with an increased risk of infections, osteoporosis and serious drug interactions. We examined the trends and predictors of PPI guidelines non-compliance(More)
BACKGROUND Despite major advances in upper GI hemorrhage (UGIH) treatment, UGIH mortality has been reported as unchanged for the past 50 years. OBJECTIVE To measure the UGIH in-hospital mortality rate and other important outcome trends from 1989 to 2009. DESIGN A longitudinal study of UGIH hospitalizations by using the Nationwide Inpatient Sample. (More)
Clostridium difficile infection (CDI) has increased sharply in incidence, mortality rate, and burden on the healthcare system over the past decade. Therefore, novel treatment modalities have been developed, including intravenous immunoglobulin (IVIG). The level of immune response to Clostridium difficile colonization is the major determinant of the(More)
We examined longitudinal associations between the apolipoprotein E ε4 allele (ApoE4(+) status) and several cognitive outcomes and tested effect modification by sex. Data on 644 non-Hispanic Caucasian adults, from the Baltimore Longitudinal Study of Aging (BLSA) were used. Dementia onset, cognitive impairment and decline were assessed longitudinally. After(More)
BACKGROUND Studies have reached varying conclusions regarding the association between day of admission and outcomes in patients with upper GI hemorrhage (UGIH). OBJECTIVES To evaluate whether important outcomes in UGIH, including in-hospital mortality, differ between patients admitted on weekends versus weekdays. DESIGN AND SETTING Retrospective cohort(More)
INTRODUCTION Dyskeratosis congenita is a rare genodermatosis, characterized by a triad of reticular skin pigmentation, nail dystrophy and leukoplakia of mucous membranes. It is also associated with a variety of non-cutaneous abnormalities such as bone marrow failure, malignancy and pulmonary complications. Among its wide range of clinical manifestations,(More)
AIMS To investigate trends in survival to hospital discharge, in-hospital expenditures, and post-acute-care disposition following out-of-hospital cardiac arrest (OHCA) in the United States. METHODS We performed this nationwide serial cross-sectional study using data from the National Inpatient Sample on all patients (age >18years) hospitalized with OHCA(More)
AIM To assess incidence of post-endoscopic retrograde cholangiopancreatography (post-ERCP) pancreatitis in the early (July/August/September) vs the late (April/May/June) academic year and evaluate in-hospital mortality, length of stay (LOS), and total hospitalization charge between these time periods. METHODS This was a retrospective cohort study using(More)
Adult-to-adult living donor liver transplantation is an increasingly important option for 17000 patients awaiting liver transplantation in the United States. However, adult-to-adult living donor liver transplantation volumes peaked in 2001 (N = 518), and have gradually fallen in 2002 (N = 362), 2003 (N = 321), and 2004 (N = 323). Recent concerns about donor(More)
