Background: A left ventricular (LV) thrombus is detected in approximately 5-10% of patients after myocardial infarction (MI). If left untreated, these LV thrombi carry a significant risk of complications including embolic stroke. According to current guidelines, anticoagulation with vitamin K antagonists (VKA) is recommended to treat a LV thrombus. Case presentation: An 87 year old patient was referred to our department with non ST-elevation MI. Five months before, he had been diagnosed with a subacute ST elevation MI, which had been treated conservatively...

BACKGROUND AND AIMS: Endoscopic cryotherapy can eradicate neoplastic Barrett's esophagus (BE). A new contact cryoballoon focal ablation system (CbFAS)) freezes esophageal mucosa with nitrous oxide. We studied the safety and efficacy of CbFAS for complete eradication of neoplastic Barrett's esophagus. METHODS: In a prospective clinical trial, consecutive BE patients with confirmed neoplasia (low-grade dysplasia LGD, high-grade dysplasia HGD, and/or intramucosal adenocarcinoma ImCA), at least 1 cm of BE, with or without prior ablation, were treated with a dose 10 seconds of spray per site...

Chemoprevention represents an attractive modality against colorectal cancer (CRC) although widespread clinical implementation of promising agents (e.g. aspirin/NSAIDS) have been stymied by both suboptimal efficacy and concerns over toxicity. This highlights the need for better agents. Several groups, including our own, have reported that the over-the-counter laxative polyethylene glycol (PEG) has remarkable efficacy in rodent models of colon carcinogenesis. In this study, we undertook the first randomized human trial to address the role of PEG in prevention of human colonic neoplasia...

BACKGROUND: Pancreatic ductal adenocarcinoma is one of the most lethal types of cancer with a 5-year survival rate of around 7%. Due to the relatively poor prognosis, the potential need of an effective chemoprevention is highly needed. SUMMARY: Different risk factors like smoking or hereditary tumour syndromes should be known for early detection of pancreatic intraepithelial neoplasia. Chemopreventive dietary agents include curcumin, capsaicin and flavonoid, whereas potential chemopreventive drugs compromise aspirin, metformin or statins...

PURPOSE OF REVIEW: The purpose of this review is to summarize the management of serrated colorectal polyps (SPs), with a particular focus on the most common premalignant SP, sessile serrated adenoma or polyp (SSA/P). These lesions present a challenge for endoscopists with respect to detection and resection, and are also susceptible to pathologic misdiagnosis. RECENT FINDINGS: Patients with SSA/Ps are at an increased risk of future colorectal neoplasia, including advanced polyps and cancer...

BACKGROUND AND AIMS: The optimal technique for the resection of sessile serrated polyps (SSPs) is unknown, with established limitations and risks with conventional polypectomy. Although cold snare polypectomy is safe, the efficacy of piecemeal resection for large lesions is untested. In this study we evaluate the safety and efficacy of cold EMR for large SSPs. METHODS: Patients presenting for elective colonoscopy at an academic endoscopy center with 1 or more SSPs ≥10 mm in size were enrolled, excluding those on anticoagulant or antiplatelet therapy other than aspirin...

BACKGROUND: Genetics plays an important role in the susceptibility to sporadic colorectal cancer (CRC). In the last 10 years genome-wide association studies (GWAS) have identified over 40 independent low penetrance polymorphic variants. However, these loci only explain around 1‑4% of CRC heritability, highlighting the dire need of identifying novel risk loci. In this study, we focused our attention on the genetic variability of the TAS2R16 gene, encoding for one of the bitter taste receptors that selectively binds to salicin, a natural antipyretic that resembles aspirin...

BACKGROUND: An electronic medical record (EMR) database of a large unselected population who received screening colonoscopies may minimize sampling error and represent real-world estimates of risk for screening target lesions of advanced colorectal neoplasia (CRN). Our aim was to develop and validate a prediction model for assessing the probability of advanced CRN using a clinical data warehouse. METHODS: A total of 49,450 screenees underwent their first colonoscopy as part of a health check-up from 2002 to 2012 at Samsung Medical Center, and the dataset was constructed by means of natural language processing from the computerized EMR system...

OBJECTIVE: Long-term acid suppression reduces the risk of progression to esophageal adenocarcinoma (EAC) in patients with Barrett's esophagus (BE). Given recent reports about the harmful effects of using chronic proton pump inhibitors (PPI) there is renewed interest in alternative methods of acid suppression. Hence, we studied the effect of H2 receptor antagonists (H2 RA) on the risk of progression to neoplasia in our BE cohort. METHODS: This is a retrospective analysis of prospectively collected data of patients in our BE registry from 2002 to 2015...

Survival from pancreatic cancer remains poor. Conventional treatment has resulted in only marginal improvements in survival compared with survival in the previous several decades. Thus, considerable interest has emerged regarding the potential use of common pharmaceutical agents as chemopreventative and chemotherapeutic options. Aspirin, metformin, statins, β-blockers, and bisphosphonates have biologically plausible mechanisms to inhibit pancreatic neoplasia, whereas dipeptidyl-peptidase 4 inhibitors may promote it...

PURPOSE: Prostaglandin-endoperoxide synthase 2 (PTGS2, cyclooxygenase-2; a target of aspirin) produces inflammatory mediator prostaglandin E2 (PGE2), and contributes to colorectal neoplasia development. PTGS2-driven inflammatory responses can induce tumor expression of microRNA MIR21 (miR-21) that can increase local PGE2 level by downregulating PGE2-metabolizing enzymes. We hypothesized that the prognostic association of tumor MIR21 expression level in colorectal carcinoma might depend on inflammatory tumor microenvironment and be stronger in tumors expressing high-level PTGS2...

Regular aspirin use reduces colon adenoma and carcinoma incidence. UDP-glucuronosyltransferases (UGT) are involved in aspirin metabolism and clearance, and variant alleles in UGT1A6 have been shown to alter salicylic acid metabolism and risk of colon neoplasia. In a randomized, cross-over, placebo-controlled trial of 44 healthy men and women, homozygous for UGT1A6*1 or UGT1A6*2, we explored differences between global epithelial and stromal expression, using Affymetrix U133 + 2.0 microarrays and tested effects of 60-day aspirin supplementation (325 mg/d) on epithelial and stromal gene expression and colon prostaglandin E2 (PGE2) levels...
