BACKGROUND Barrett's esophagus, a condition of intestinal metaplasia of the esophagus, is associated with an increased risk of esophageal adenocarcinoma. We assessed whether endoscopic radiofrequency ablation could eradicate dysplastic Barrett's esophagus and decrease the rate of neoplastic progression. METHODS In a multicenter, sham-controlled trial, we(More)
BACKGROUND & AIMS Data regarding the health care costs of inflammatory bowel disease (IBD) in the United States are limited. The objectives of this study were to estimate the direct costs of Crohn's disease (CD) and ulcerative colitis (UC) in the United States, describe the distribution of costs among inpatient, outpatient, and pharmaceutical services, and(More)
Studies of acute liver failure from drugs have included cases mostly attributed to acetaminophen (APAP) but have reported limited data on other drugs. We used the United Network for Organ Sharing (UNOS) liver transplant database from 1990 to 2002 to identify recipients and estimate a U.S. population-based rate of liver transplantation due to acute liver(More)
OBJECTIVE To examine associations of the frequency of eating at fast-food restaurants with demographic, behavioural and psychosocial factors and dietary intake in African American adults. METHODS Self-reported data from a population-based cross-sectional survey of 658 African Americans, aged 20-70 years, in North Carolina. An 11-page questionnaire(More)
BACKGROUND Prostate cancer (PC) mortality is much greater for African American than for Caucasian men. To identify patient factors that might account for some of this disparity, men within 6 months of diagnosis were surveyed about health attitudes and behavior. METHODS Using Rapid Identification in the North Carolina Cancer Registry, 207 African American(More)
Differences in the composition of the gut microbial community have been associated with diseases such as obesity, Crohn's disease, ulcerative colitis and colorectal cancer (CRC). We used 454 titanium pyrosequencing of the V1-V2 region of the 16S rRNA gene to characterize adherent bacterial communities in mucosal biopsy samples from 33 subjects with adenomas(More)
OBJECTIVE To determine the natural history of pancreatitis-induced splenic vein thrombosis with particular attention to the risk of gastric variceal hemorrhage. SUMMARY BACKGROUND DATA Previous studies have suggested that splenic vein thrombosis results in a high likelihood of gastric variceal bleeding and that splenectomy should be performed to prevent(More)
Compelling evidence from epidemiologic studies indicates that elevated circulating insulin-like growth factor (IGF)-I, insulin resistance, and associated complications, such as elevated fasting plasma insulin, glucose and free fatty acids, glucose intolerance, increased body mass index, and visceral adiposity, are linked with increased risk of colorectal(More)
The association between obesity and colorectal neoplasia may be mediated by inflammation. Circulating levels of C-reactive protein (CRP), interleukin-6 (IL-6), and tumor necrosis factor-alpha (TNF-alpha) are elevated in the obese. Adipose tissue can produce and release the inflammatory cytokines that are potentially procarcinogenic. We examined circulating(More)
Colorectal cancer and diabetes are common diseases that share many risk factors. It has been hypothesized that diabetes is a risk factor for colorectal cancer. We used two large population-based case-control studies from North Carolina to determine whether diabetes and/or insulin therapy was associated with colon cancer and/or rectal cancer (defined as(More)
