OBJECTIVE The authors used color photographs of emotional and neutral expressions to investigate recognition patterns of five universal emotions in schizophrenia. METHOD Twenty-eight stable outpatients with schizophrenia (19 men and nine women) and 61 healthy subjects (29 men and 32 women) completed an emotion discrimination test that presented mild and(More)
The facial action coding system (FACS) was used to examine recognition rates in 105 healthy young men and women who viewed 128 facial expressions of posed and evoked happy, sad, angry and fearful emotions in color photographs balanced for gender and ethnicity of poser. Categorical analyses determined the specificity of individual action units for each(More)
BACKGROUND & AIMS Previous studies of the risk of lymphoma in inflammatory bowel disease patients have provided conflicting results. This study examines the risk of Hodgkin's and non-Hodgkin's lymphoma among patients with inflammatory bowel disease. METHODS The authors performed a retrospective cohort study using the General Practice Research Database.(More)
BACKGROUND Inflammatory bowel disease (IBD) is commonly treated with immunomodulators such as azathioprine and 6-mercaptopurine (6-MP). Studies examining lymphoma risk in IBD patients treated with these medications have been underpowered and have yielded conflicting conclusions. AIMS The purpose of this meta-analysis was to provide a more precise estimate(More)
The goal of the study was to develop and apply a predictive model approach to reduce the number of items collected for scales that yield a total summary score. A parsimonious subset of items from the 21-item Quality of Life Scale (QLS) that can accurately predict the total scale score was sought and evaluated in 198 patients with schizophrenia, using a(More)
The objective of this study was to determine whether two vitamin K epoxide reductase complex 1 (VKORC1) polymorphisms contribute to the variability in warfarin response, particularly in African Americans. The effect of the VKORC1 1173C/T and -1639G/A polymorphisms was examined in a prospective cohort study of 338 warfarin users. Subjects carrying an 1173T(More)
Sex differences in executive speech tasks, favoring women, have been noted in behavioral studies and functional imaging studies. In the present study, the clustering and switching components of semantic and phonemic verbal fluency tests were examined in 40 healthy men and 40 healthy women. Possible sex differences in the influence of cognitive factors such(More)
OBJECTIVES Biliary casts develop in up to 18% of liver transplant recipients. Casts are associated with morbidity, graft failure, need for retransplantation, and mortality. Proposed etiological mechanisms include acute cellular rejection, ischemia, infection, and biliary obstruction. We aimed to identify clinical features associated with biliary cast(More)
OBJECTIVES The purpose of this study was to investigate whether a surrogate for renal neurohormonal activation, blood urea nitrogen (BUN), could identify patients destined to experience adverse outcomes associated with the use of high-dose loop diuretics (HDLD). BACKGROUND Loop diuretics are commonly used to control congestive symptoms in heart failure;(More)
BACKGROUND & AIMS Placebo-controlled, randomized clinical trials (PC-RCTs) are commonly used to assess therapies for Crohn's disease (CD). Knowledge of the placebo rates of remission and response and understanding of design factors that influence these rates is important for designing future clinical trials evaluating pharmacotherapy of CD. The aims of this(More)
