Gastric ulcers: malignancy yield and risk stratification for follow-up endoscopy.

Background And Study Aim: Malignant change can occur in gastric ulcer but guideline recommendations for follow-endoscopy (FU-OGD) are conflicting. This study aims to determine rate of malignancy and need for follow-up for gastric ulcers.

Patients And Methods: Patients with a first diagnosis of gastric ulcer between January 2012 and September 2013 were studied by analyzing endoscopic assessments, dysplasia, and malignancy yield and the influence of risk factors on the likelihood of benign disease.

Prevalence of irritable bowel syndrome-type symptoms in patients with celiac disease: a meta-analysis.

Background & Aims: Patients with celiac disease (CD) often report symptoms compatible with irritable bowel syndrome (IBS). However, the prevalence of these symptoms in patients with CD and their relation to adherence to a gluten-free diet (GFD) have not been assessed systematically.

Methods: We searched MEDLINE, EMBASE, and EMBASE Classic (through July 2012) to identify cross-sectional surveys or case-control studies reporting prevalence of IBS-type symptoms in adult patients (≥ 16 years old) with established CD.

Treatment of irritable bowel syndrome: beyond fiber and antispasmodic agents.

Irritable bowel syndrome (IBS) is a chronic functional disorder of the gastrointestinal tract of unknown etiology. The diagnosis of IBS is made clinically, using symptom-based criteria such as the Manning or Rome criteria. Medical therapy for this condition has traditionally been directed towards symptom relief, using fiber or antispasmodic agents.

Rectal epithelial cell mitosis and expression of macrophage migration inhibitory factor are increased 3 years after Roux-en-Y gastric bypass (RYGB) for morbid obesity: implications for long-term neoplastic risk following RYGB.

Background: Rectal epithelial cell mitosis and crypt size, as well as expression of proinflammatory genes including macrophage migration inhibitory factor (MIF), are increased 6 months after Roux-en-Y gastric bypass (RYGB) in morbidly obese patients. Tests were carried out to determine whether these putative colorectal cancer risk biomarkers remained elevated long term after RYGB, and the mechanistic basis, as well as the functional consequences, of Mif upregulation in intestinal epithelial cells was investigated.

Methods: Rectal mucosa and blood were obtained a median of 3 years after RYGB from the original cohort of patients with RYGB (n = 19) for crypt microdissection, real-time PCR, immunohistochemistry for MIF and immunoassay of proinflammatory markers.

Increased colorectal epithelial cell proliferation and crypt fission associated with obesity and roux-en-Y gastric bypass.

Background And Aims: The relationship between obesity, weight reduction, and future risk of colorectal cancer is not well understood. Therefore, we compared mucosal biomarkers in normal weight individuals [body mass index (BMI), 18.5-24.

Reliability of the Barthel Index when used with older people.

Objective: the Barthel Index (BI) has been recommended for the functional assessment of older people but the reliability of the measure for this patient group is uncertain. To investigate this issue we undertook a systematic review to identify relevant studies from which an overview is presented.

Method: studies investigating the reliability of the BI were obtained by searching Medline, Cinahl and Embase to January 2003.
