      BACKGROUND: To our knowledge, no detailed analysis exists of the incidence and mortality of hepatocellular carcinoma (HCC) among Hispanics in the United States. In previous studies, the rates for Hispanics have not been reported separately from other racial or ethnic groups.

      METHODS: We used information on patients diagnosed as having HCC from 13 registries in the Surveillance Epidemiology and End Results (SEER) database of the National Cancer Institute to calculate race-specific, ...

      OBJECTIVES: Although inflammatory bowel disease (IBD) has been reported worldwide, most studies have focused on Caucasian populations. Our aim was to summarize the existing epidemiological literature, identify temporal trends, and highlight areas for future research.

      METHODS: We carried out a systematic review following standard guidelines to evaluate the incidence, prevalence, temporal trends, disease characteristics, and extra-intestinal manifestations (EIMs) of IBD in African ...

      BACKGROUND & AIMS: Hepatocellular carcinoma (HCC) can develop in individuals without cirrhosis. We investigated risk factors for development of HCC in the absence of cirrhosis in a U.S.

      METHODS: We identified a national cohort of 1500 patients with verified HCC during 2005 to 2010 in the U.S. Veterans Administration (VA) and reviewed their full VA medical records for evidence of cirrhosis and risk factors for HCC. Patients without cirrhosis were assigned to categories of level 1 evidence ...

      Surveillance for hepatocellular carcinoma (HCC) in patients with cirrhosis is recommended but may not be performed. The extent and determinants of HCC surveillance are unknown. We conducted a population-based United States cohort study of patients over 65 years of age to examine use and determinants of prediagnosis surveillance in patients with HCC who were previously diagnosed with cirrhosis. Patients diagnosed with HCC during 1994-2002 were identified from the linked Surveillance, ...

      BACKGROUND AND AIMS: The risk of hepatocellular cancer (HCC) after sustained virological response (SVR) with direct-acting antivirals (DAA) is unclear. Our aim was to examine the risk and determinants of HCC in patients cured with DAA.

      METHODS: We conducted a retrospective cohort study of hepatitis C virus patients who were treated with DAA in any of the 129 Veterans Health Administration hospitals between January 1, 2015 and December 31, 2015. We calculated the annual incidence rates of ...

      BACKGROUND & AIMS: There are limited data on the risk of hepatocellular cancer (HCC) in patients with non-alcoholic fatty liver disease (NAFLD). We aimed to estimate the risk of incident HCC among patients with NAFLD.

      METHODS: We conducted a retrospective cohort study from a total of 130 facilities in the Veterans Health Administration. Patients with NAFLD diagnosed between January 1, 2004 and December 31, 2008 were included and followed until HCC diagnosis, death, or December 31, 2015. ...

      BACKGROUND & AIMS: Early detection of hepatocellular carcinoma (HCC) through surveillance reduces mortality associated with this cancer. Guidelines recommend HCC surveillance every 6 months for patients with cirrhosis, via ultrasonography, with or without measurement of serum level of alpha fetoprotein (AFP).

      METHODS: We previously developed and internally validated an HCC early detection screening (HES) algorithm that included patient's current level of AFP, rate of AFP change, age, ...

      BACKGROUND & AIMS: Patients with hepatitis C virus (HCV) infection are at risk for developing costly and morbid complications, although the actual prevalence of these complications is unknown. We examined time trends in the prevalence of cirrhosis and its related complications, such as hepatic decompensation and hepatocellular carcinoma (HCC).

      METHODS: We calculated the annual prevalence of cirrhosis, decompensated cirrhosis, and HCC in a national sample of veterans diagnosed with HCV ...

      BACKGROUND & AIMS: Intrahepatic and extrahepatic cholangiocarcinomas are rare and highly malignant cancers of the bile duct. Although the incidence of extrahepatic cholangiocarcinoma (ECC) has remained constant, the incidence of intrahepatic cholangiocarcinoma (ICC) has increased in the United States. Because the etiology of both tumors is poorly understood, a population-based case-control study was conducted to examine the association of ECC and ICC with preexisting medical ...

      BACKGROUND & AIMS: Cirrhosis related to chronic hepatitis B (CHB) is a major risk factor for hepatocellular carcinoma (HCC). The extent to which HCC occurs in U.S. in the absence of cirrhosis in CHB remains unclear.

      METHODS: We identified CHB patients who were diagnosed with HCC in the national Veterans Administration (VA) between 2001 and 2013. We defined presence and absence of cirrhosis at the time of HCC diagnosis using explicit histological, radiological, endoscopic, and laboratory ...

      BACKGROUND: Gastroesophageal reflux disease (GERD) reduces sleep quality. Whether Barrett's esophagus (BE) affects sleep differently is unknown. Obstructive sleep apnea (OSA) often coexists with GERD and may disrupt sleep; whether GERD reduces sleep quality independently of OSA is unknown. Our aims were to compare the effect of GERD and BE on sleep quality, and assess the impact of OSA on this association.

      METHODS: Validated questionnaires for GERD symptoms, sleep quality, and OSA risk ...

      PURPOSE: Symptoms of gastroesophageal reflux disease (GERD) occur in 2% to 7% of children. The manifestations of GERD can be limited to symptoms (eg, heartburn, regurgitation) or can be more complicated, such as erosive esophagitis, esophageal strictures, or Barrett esophagus. The prevalence of such GERD complications in children is unknown. The purpose of this study was to determine the prevalence of endoscopic findings of erosive esophagitis in children.

      Incidence rates of hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (ICC) have increased in the United States. Metabolic syndrome is recognized as a risk factor for HCC and a postulated one for ICC. The magnitude of risk, however, has not been investigated on a population level in the United States. We therefore examined the association between metabolic syndrome and the development of these cancers. All persons diagnosed with HCC and ICC between 1993 and 2005 were ...

      BACKGROUND & AIMS: Serum levels of α-fetoprotein (AFP) are influenced not only by the presence of hepatocellular carcinoma (HCC), but also by the underlying severity and activity of liver disease, which is reflected by liver function tests. We constructed an AFP-based algorithm that included these factors to identify patients at risk for HCC, and tested its predictive ability in a large set of patients with cirrhosis.

      METHODS: We used the national Department of Veterans Affairs Hepatitis ...

      BACKGROUND & AIMS: Limited evidence suggests that proton pump inhibitors (PPI), nonsteroidal anti-inflammatory drugs (NSAID)/aspirin, and statins may be associated with a low risk of esophageal neoplasia. However, the possible effect these medications may have on the risk of esophageal adenocarcinoma (EAC) in patients with existing Barrett's esophagus (BE) is unclear.

      METHODS: We conducted a nested case-control study in a cohort of patients with BE identified in the national Department ...
