Safety and efficacy of non-steroidal anti-inflammatory drugs to reduce ileus after colorectal surgery
Ileus is common after elective colorectal surgery, and is associated with increased adverse events and prolonged hospital stay. The aim was to assess the role of non-steroidal anti-inflammatory drugs (NSAIDs) for reducing ileus after surgery.A prospective multicentre cohort study was delivered by an international, student- and trainee-led collaborative group. Adult patients undergoing elective colorectal resection between January and April 2018 were included. The primary outcome was time to gastrointestinal recovery, measured using a composite measure of bowel function and tolerance to oral intake. The impact of NSAIDs was explored using Cox regression analyses, including the results of a c…
Safety of hospital discharge before return of bowel function after elective colorectal surgery
Ileus is common after colorectal surgery and is associated with an increased risk of postoperative complications. Identifying features of normal bowel recovery and the appropriateness for hospital discharge is challenging. This study explored the safety of hospital discharge before the return of bowel function.A prospective, multicentre cohort study was undertaken across an international collaborative network. Adult patients undergoing elective colorectal resection between January and April 2018 were included. The main outcome of interest was readmission to hospital within 30 days of surgery. The impact of discharge timing according to the return of bowel function was explored using multiva…
Adenocarcinomas and their derived lymphovascular emboli contain dual compartmental populations of tumor microvesicles which differ in size and possibly content and function.
Adenocarcinomas and their associated lymphovascular emboli metastasize as tight aggregates of tumor cells. Using a xenograft model of human inflammatory breast cancer (Mary-X), which exhibited florid lymphovascular emboli in mice and high density tumor aggregates (spheroids) in vitro, we previously demonstrated that both emboli and spheroids are mediated by an intact overexpressed E-cadherin axis which regulates homotypic tumor cell adhesion. We now report that Mary-X spheroids secrete 5-10 fold higher levels of microvesicles (MVs) than most other carcinoma cell lines. Despite the high density of tumor cells and the strong juxtaposition of tumor cells to each other in the spheroids, interce…
Linkage disequilibrium screening for multiple sclerosis implicates JAG1 and POU2AF1 as susceptibility genes in Europeans.
By combining all the data available from the Genetic Analysis of Multiple sclerosis in EuropeanS (GAMES) project, we have been able to identify 17 microsatellite markers showing consistent evidence for apparent association. As might be expected five of these markers map within the Major Histocompatibility Complex (MHC) and are in LD with HLA-DRB1. Individual genotyping of the 12 non-MHC markers confirmed association for three of them — D11S1986, D19S552 and D20S894. Association mapping across the candidate genes implicated by these markers in 937 UK trio families revealed modestly associated haplotypes in JAG1 (p=0.019) on chromosome 20p12.2 and POU2AF1 (p=0.003) on chromosome 11q23.1.
