C. elegans PUD-1 and PUD-2, two proteins up-regulated in daf-2(loss-of-function) (PUD), are homologous 17-kD proteins with a large abundance increase in long-lived daf-2 mutant animals of reduced insulin signaling. In this study, we show that both PUD-1 and PUD-2 are abundantly expressed in the intestine and hypodermis, and form a heterodimer. We have solved their crystal structure to 1.9-Å res...

BACKGROUND/AIMS Peptic ulcer disease (PUD) is a common condition, but is difficult to detect in asymptomatic individuals. We aimed to investigate the prevalence of symptomatic and asymptomatic PUD during screening endoscopy and to identify risk factors for the presence of symptoms in patients with PUD. METHODS We investigated subjects who underwent a health inspection, including endoscopy of ...

BACKGROUND/AIMS Our aim was to compare the long-term clinical outcomes of idiopathic peptic ulcer disease (IPUD) with those of Helicobacter pylori-positive and nonsteroidal anti-inflammatory drug (NSAID)-induced peptic ulcer disease (PUD). METHODS Patients with endoscopically diagnosed PUD were retrospectively reviewed. According to their H. pylori-infection status and history of NSAIDs use, ...

BACKGROUND The aim of this study was to analyse the risk of uncomplicated peptic ulcer disease (PUD) in a cohort of new users of low-dose acetylsalicylic acid (ASA) for secondary prevention of cardiovascular events in a UK primary care setting. METHODS New users of low-dose ASA for secondary prevention of cardiovascular events, aged 50-84 years in 2000-2007, were identified from The Health Im...

Background. Helicobacter pylori (HP) infection and nonsteroidal anti-inflammatory drugs (NSAID) use are considered the main risk to develop peptic ulcer disease (PUD). However, PUD also occurs in the absence of HP infection and/or NSAID use. Recently, we have found evidence that Epstein-Barr virus (EBV) reactivation increases the risk to develop premalignant and malignant gastric lesions. Objec...

BACKGROUND Few epidemiologic studies have investigated predictors of uncomplicated peptic ulcer disease (PUD) separately from predictors of complicated PUD. OBJECTIVE To analyze risk factors associated with uncomplicated PUD and medication use after diagnosis. METHODS Patients diagnosed with uncomplicated PUD (n = 3,914) were identified from The Health Improvement Network database among ind...

BACKGROUND Distinguishing the rates of Helicobacter pylori infection in chronic kidney disease (CKD) and end-stage renal disease (ESRD) patients with peptic ulcer disease (PUD) from that in PUD patients without CKD is critical. METHODS We first stratified the original 1 million study population according to CKD or ESRD. We retrospectively investigated the incidence of H. pylori infection in P...

OBJECTIVES Peptic ulcer disease (PUD) is a common disorder, but whether an association exists between PUD and anthropometric indicators remains controversial. Furthermore, no studies on the association of PUD with anthropometric indices, blood parameters, and nutritional components have been reported. The aim of this study was to assess associations of anthropometrics, blood parameters, nutriti...

OBJECTIVE Previous studies have documented links between peptic ulcer disease (PUD) and mood and anxiety disorders among adults in the community. Several substance use disorders (e.g., nicotine and alcohol dependence) are highly comorbid with mood/anxiety disorders and have been also linked with PUD. No previous study has examined the potentially explanatory role of substance use disorders in t...

Sleep is integral to life and sleep duration is important in sleep quality, physical, and psychological health. Disturbances in sleep duration have been associated with increased risk of metabolic disorders, hypertension, and overall mortality. Sleep disturbance has also been linked with various gastrointestinal disorders. However, the association between sleep and peptic ulcer disease (PUD) ha...
