Despite limitations, this study lends some reassurance that risk of osteoporosis is not likely to overshadow the benefit of proton pump inhibitors in preventing recurrent peptic ulcer, esophageal reflux symptoms, and esophageal cancer risk.
This study ought to put concerns about handling and administration of donor feces to rest: the cure rate in this study of fecal microbiota transplant for recurrent C difficile approached 95%.
New insights into how clinicians might approach treatment for patients with IBD highlighted the recent Crohn’s & Colitis Foundation’s Clinical & Research Conference.
The goals of therapy for patients with inflammatory bowel disorder include inducing and maintaining a steroid-free remission, preventing and treating the complications of the disease, minimizing treatment toxicity, achieving mucosal healing, and enhancing quality of life. More in this podcast.
All patients with IBD should receive aggressive ongoing assessment of their inflammatory state and its response to immunomodulators, anti-TNF drugs, and other agents.
Christopher Pleyer, MD, from the Mayo Clinic, Rochester, MN, summarizes his part in the plenary session "Observer Bias in the Diagnosis of Gastroesophageal Reflux Disease and Functional Dyspepsia" at ACG 2011. Distinguishing GERD from other upper GI problems is crucial, he explains.
Is obesity really leading to an increase in GERD? Or, has GERD just become a catch-all phrase for all sorts of upper GI distress? Has GERD become the new "dyspepsia"? G. Richard Locke, MD, FACG, from the Mayo Clinic, Rochester, MN, discusses his findings as presented at the ACG 2011 program.

Postoperative surgical-site infections are a major source of morbidity and cost. This study aimed to identify and present all randomized controlled trial evidence evaluating the effects of dressings on surgical-site infection rates in surgical wounds healing by primary intention; the secondary outcomes included comparisons of pain, scar and acceptability between dressings.|Randomized controlled trials comparing alternative wound dressings, or wound dressings with leaving wounds exposed for postoperative management of surgical wounds were included in the review regardless of their language. Databases searched included the Cochrane Wounds Group Specialised Register and Central Register of Controlled Trials, Ovid MEDLINE, Ovid Embase and EBSCO CINAHL from inception to May 2011. Two authors performed study selection, risk of bias assessment and data extraction, including an assessment of surgical contamination according to the surgical procedure. Where levels of clinical and statistical
To evaluate the relationship between age and clinicopathological characteristics in gastric carcinoma patients, we performed the meta-analysis based on nine retrospective clinical trials. Comparing elderly patients with young patients it showed lower male/female ratio, more diffuse GC, more Borrmann type IV, more poorly differentiated carcinoma, more peritoneal metastasis, less vascular invasion, fewer partial resections, and better 5-year survival rate. These particular age-related characteristics need to be further investigated.
This study aimed to validate two prognostic biomarkers, pfetin and adenosine triphosphate-dependent RNA helicase DDX39 (DDX39), in gastrointestinal stromal tumour. Prognostic biomarkers have long been required for the optimal use of kinase inhibitors in gastrointestinal stromal tumour.|The expression level of pfetin was immunohistochemically examined in 72 gastrointestinal stromal tumour cases, being correlated with the clinicopathological parameters. Meta-analysis of the prognostic value of pfetin was performed in a total of 371 cases. The prognostic utility of the combination of pfetin and DDX39 was examined in the 72 gastrointestinal stromal tumour cases.|Immunohistochemical study demonstrated the disease-free survival rate to be 94.7% for pfetin-positive patients and 20.0% for pfetin-negative patients among the 72 gastrointestinal stromal tumour cases (P < 0.0001). In the 371 cases, the disease-free survival rate was 93.8% for pfetin-positive patients and 40.6% for pfetin-negative
To determine the effect of allogeneic blood transfusion (ABT) on clinical outcomes in patients with colorectal cancer undergoing surgery.|Perioperative ABTs may be associated with adverse clinical outcomes.|Systematic review of the literature with odds ratio (OR) and incidence rate ratio (IRR) meta-analyses of predefined clinical outcomes based on a MEDLINE search.|In total, 20,795 colorectal cancer (CRC) patients observed for more than 59.2 26.1 months (108,838 patient years) were included, of which 58.8% were transfused. ABT was associated with increased all-cause mortality OR = 1.72 (95% confidence interval [CI] 1.55-1.91, P < 0.001); I(2) = 23.3% (0-51.1) and IRR = 1.31 (1.23-1.39, P < 0.001), I(2) = 0.0% (0-37.0). ABT was also associated with increased ORs (95% CI, P) for cancer-related mortality of 1.71 (1.43-2.05, P <0.001), combined recurrence-metastasis-death 1.66 (1.41-1.97, P < 0.001), postoperative infection 3.27 (2.05-5.20, P < 0.001), and surgical reintervention 4.08
We studied marginal zone B-cell lymphomas of the gastrointestinal tract including seven small cell lymphomas, eight large cell areas of composite lymphomas and 13 large cell variants using SNP array profiling. We found an increase of genomic complexity with lymphoma progression from small to large cytology, and identified gains of prominent (proto) oncogenes such as REL, BCL11A, ETS1, PTPN1, PTEN and KRAS which were found exclusively in the large cell variants. Copy numbers of ADAM3A, SCAPER and SIRPB1 were varying between the three different modes of presentation, hence suggestive for aberrations associated with progression from small to large cell lymphoma. The number of aberrations was slightly higher in the large cell part of composite lymphomas than in large cell lymphomas, suggesting that clonal selection takes place and that composite lymphomas are in a transition state. To further investigate this, we comparatively analyzed samples of two morphologically different regions of
Until now, only imatinib and sunitinib have proven clinical benefit in patients with gastrointestinal stromal tumours (GIST), but almost all metastatic GIST eventually develop resistance to these agents, resulting in fatal disease progression. We aimed to assess efficacy and safety of regorafenib in patients with metastatic or unresectable GIST progressing after failure of at least imatinib and sunitinib.|We did this phase 3 trial at 57 hospitals in 17 countries. Patients with histologically confirmed, metastatic or unresectable GIST, with failure of at least previous imatinib and sunitinib were randomised in a 2:1 ratio (by computer-generated randomisation list and interactive voice response system; preallocated block design (block size 12); stratified by treatment line and geographical region) to receive either oral regorafenib 160 mg daily or placebo, plus best supportive care in both groups, for the first 3 weeks of each 4 week cycle. The study sponsor, participants, and
Celiac disease is an inflammatory condition of the small intestinal mucosa induced by gluten consumption in genetically susceptible individuals, leading to a spectrum of gastrointestinal presentation. A number of autoimmune and other disorders are highly associated with celiac disease. Cardiomyopathy associated with celiac disease has been rarely reported in the literature.|We present a case of a 27-year-old male with one month history of diarrhea, weight loss, fatigue, dyspeptic symptoms, peripheral edema, and cardiac palpitations. After positive serological screening with immunoglobulin A anti-tissue transglutaminase antibody test, the diagnosis of celiac disease was confirmed with histopathology examination of duodenal biopsy specimen. Echocardiographic findings were consistent with acute myocarditis. After common causes of myocarditis had been excluded, probable celiac disease-associated autoimmune myocarditis was diagnosed. The patient was recommended to undergo a strict

The hemoglobin threshold for transfusion of red cells in patients with acute gastrointestinal bleeding is controversial. We compared the efficacy and safety of a restrictive transfusion strategy with those of a liberal transfusion strategy.|We enrolled 921 patients with severe acute upper gastrointestinal bleeding and randomly assigned 461 of them to a restrictive strategy (transfusion when the hemoglobin level fell below 7 g per deciliter) and 460 to a liberal strategy (transfusion when the hemoglobin fell below 9 g per deciliter). Randomization was stratified according to the presence or absence of liver cirrhosis.|A total of 225 patients assigned to the restrictive strategy (51%), as compared with 65 assigned to the liberal strategy (15%), did not receive transfusions (P<0.001). The probability of survival at 6 weeks was higher in the restrictive-strategy group than in the liberal-strategy group (95% vs. 91%; hazard ratio for death with restrictive strategy, 0.55; 95% confidence
