Abstract Purpose Patients with inflammatory bowel disease (IBD), whether Crohn’s disease (CD) or ulcerative colitis (UC), have an increased risk of acute pancreatitis. The prognostic value of diagnosing acute idiopathic pancreatitis in patients with IBD is not well understood. Methods A retrospective review of 56 patients with IBD and acute pancreatitis was conducted in a tertiary center from 2011 to 2020. Aggressive disease course was defined as (i)biologic change, (ii)biologic dose escalation, or (iii)IBD-related surgeries occurring within 1 year of acute pancreatitis diagnosis. Logistic regression modelling identified associations between covariates and an aggressive disease course. Results Baseline characteristics between idiopathic pancreatitis and other causes of acute pancreatitis, in both CD and UC cohorts, were similar. Idiopathic pancreatitis was significantly associated with an aggressive disease course in CD (P = 0.04). No confounding factors were associated with an aggressive disease course in CD. Idiopathic pancreatitis, however, was not associated with an aggressive disease course in UC (P = 0.35). Conclusion The diagnosis of acute idiopathic pancreatitis may provide a prognostic indicator of a more severe disease course in CD. No such association appears to exist with UC. To the best of our knowledge, this is the first study that identifies an association and possible prognostic value between idiopathic pancreatitis and a more severe disease course in CD. More studies with a larger sample size are needed to validate these findings, further define idiopathic pancreatitis as an extraintestinal manifestation of IBD and elucidate a clinical strategy to optimize care in patients with aggressive CD and idiopathic pancreatitis.

Background and Aims: Published literature shows mixed reports of the benefits of nonsteroidal anti-inflammatory drugs (NSAIDs) on reducing colorectal polyps in patients with familial adenomatous polyposis (FAP). We conducted a systematic review and performed a meta-analysis to assess the impact of NSAIDs on colorectal polyp burden in patients with FAP. Methods: We searched PubMed, EMBASE, and Cochrane for randomized controlled trials (RCTs) comparing the effect of NSAIDs vs placebo on the percent change in polyp number and polyp size in patients with FAP. Mean differences between the 2 study arms were pooled using RevMan. The risk of bias (RoB) was assessed using the Cochrane Risk of Bias tool for RCTs, and certainty in the evidence was assessed using the Grading of Recommendations Assessment, Development, and Evaluation methodology. Results: The search strategy identified 1021 studies, out of which we included 8 RCTs with a total of 279 patients. Treatment for 6.4 ± 2.2 months with NSAIDs reduced polyp numbers by −17.4% (95% confidence interval −26.41%, −8.29%) (low certainty [I2 89%] due to imprecision and issues with RoB) and polyp size by −15.9% (95% confidence interval −24.98%, −6.73%) (very low certainty (I2 84%) due to imprecision, inconsistency, and issues with RoB). The most common gastrointestinal adverse events reported were stomatitis, diarrhea, and abdominal pain. Side effects leading to drug discontinuation were gastroenteritis and drug allergy. Conclusion: Short-term use of NSAIDs reduced polyp number and polyp size but with low to very low certainty of evidence. Further large multicenter studies are needed to further explore NSAIDs as a chemopreventive measure in patients with FAP.

Background: The level of radiation exposure received by operators performing transcatheter aortic valve replacement (TAVR) is not well investigated. The aim of this study is to measure the amount of radiation received by operators performing transfemoral TAVR and to identify various patient and procedural characteristics associated with increased radiation exposure. Methods: Primary (operator 1) and secondary (operator 2) operators' equivalent radiation doses in micro Sieverts (µSv) were calculated prospectively using real-time radiation dosimeters for a total of 140 consecutive transfemoral TAVRs. Corresponding eye and thorax radiation exposures between the operators were compared. Associations between various patient and procedural characteristics and the radiation exposure were tested using the t-test and Wilcoxon Mann-Whitney rank-sum test with Monte Carlo estimation. Multivariable regression analysis was also conducted. Results: Operator 1 had significantly higher cumulative equivalent radiation exposure than operator 2 (86 µSv vs 38 µSv, p-value:

Abstract Introduction The purpose of this meta-analysis is to compare the efficacy of MitraClip plus medical therapy versus medical therapy alone in patients with functional mitral regurgitation (FMR). FMR caused by left ventricular dysfunction is associated with poor prognosis. Whether MitraClip improves clinical outcomes in this patient population remains controversial. Methods We conducted an electronic database search of PubMed, CINAHL, Cochrane Central, Scopus, Google Scholar, and Web of Science databases for randomized control trials (RCTs) and observational studies with propensity score matching (PSM) that compared MitraClip plus medical therapy with medical therapy alone for patients with FMR and reported on subsequent mortality, heart failure re-hospitalization, and other outcomes of interest. Event rates were compared using a random-effects model with odds ratio as the effect size. Results Five studies (n = 1513; MitraClip = 796, medical therapy = 717) were included in the final analysis. MitraClip plus medical therapy compared to medical therapy alone was associated with a significant reduction in overall mortality (OR = 0.66, 95% CI = 0.44–0.99, P = 0.04) and heart failure (HF) re-hospitalization rates (OR = 0.57, 95% CI = 0.36–0.91, P = 0.02). There was reduced need for heart transplantation or mechanical support requirement (OR = 0.48, 95% CI = 0.25–0.91, P = 0.02) and unplanned mitral valve surgery (OR = 0.21, 95% CI = 0.07–0.61, P = 0.004) in the MitraClip group. No effect was observed on cardiac mortality (P = 0.42) between the two groups. Conclusions MitraClip plus medical therapy improves overall mortality and reduces HF re-hospitalization rates compared to medical therapy alone in patients with FMR.

Objectives: The objective of this study was to compare safety and efficacy of patent foramen ovale (PFO) closure compared with medical therapy in patients with cryptogenic stroke (CS). Background: The role of PFO closure in preventing recurrent stroke in patients with prior CS has been controversial. Methods: We searched PubMed, EMBASE, the Cochrane Central Register of Controlled trials, and the clinical trial registry maintained at clinicaltrials.gov for randomized control trials that compared device closure with medical management and reported on subsequent stroke and adverse events. Event rates were compared using a forest plot of relative risk using a random-effects model assuming interstudy heterogeneity. Results: A total of 6 studies (n = 3747) were included in the final analysis. Mean follow-up ranged from 2 to 5.9 years. Pooled analysis revealed that device closure compared to medical management was associated with a significant reduction in stroke (risk ratio [RR] = 0.41, 95% CI = 0.20–0.83, I2 = 51%, P = 0.01). There was, however, a significant increase in atrial fibrillation with device therapy (RR = 5.29, 95% CI = 2.32–12.06, I2 = 38%, P
