CONTEXT The epidemic of heart failure has yet to be fully investigated, and data on incidence, survival, and sex-specific temporal trends in community-based populations are limited. OBJECTIVE To test the hypothesis that the incidence of heart failure has declined and survival after heart failure diagnosis has improved over time but that secular trends have diverged by sex. DESIGN, SETTING, ...

BACKGROUND The incidence of Clostridium difficile infection (CDI) is increasing, even in populations previously thought to be at low risk, including children. Most incidence studies have included only hospitalized patients and are thus potentially influenced by referral or hospitalization biases. METHODS We performed a population-based study of CDI in pediatric residents (aged 0-18 years) of ...

BACKGROUND AND AIMS It has been suggested that gastric cardia adenocarcinoma (GCA) is a distinct entity from oesophageal adenocarcinoma (OA). We examined several epidemiological features of GCA and OA in the USA to elucidate differences/similarities between these malignancies. METHODS Using the database of Surveillance, Epidemiology, and End Results (SEER) program, we examined incidence rates...

BACKGROUND Knowledge of the burden and causes of sudden cardiac death (SCD) is sparse in persons aged<50 years; better understanding is needed to lower the risk of SCD. The aim of this study was to report SCD incidence rates and autopsy findings in persons aged 1 to 49 years. METHODS AND RESULTS All deaths in persons aged 1 to 49 years were included in 2007 to 2009. Death certificates were re...

BACKGROUND A test for hepatitis C virus (HCV) RNA is essential to identify persons with active, or current, HCV infection. We assessed trends in HCV RNA testing following a positive HCV antibody result among persons in 4 large healthcare organizations.
