BACKGROUND: Colonic interposition is a second-line option after oesophagectomy when a gastric neo-oesophagus is not viable. There is no consensus on the optimum anatomical colonic conduit (right or left), or route of placement (posterior mediastinal, retrosternal or subcutaneous). The aim of this review was to determine the optimum site and route of neo-oesophageal conduit after adult oesophagectomy. METHODS: PubMed, MEDLINE, and the Cochrane Library (January 1985 to January 2017) were systematically searched for studies which reported outcomes following colonic interposition in adults...

Colorectal cancer (CRC) is a significant cause of morbidity and mortality. Optical colonoscopy (OC) is the first choice of investigation for assessing the state of the colon and it is excellent for CRC screening. Newer technologies such as computed tomography colonography (CTC) may also be useful in CRC screening. This systematic review compares the benefits of CTC and OC for CRC screening. This review includes all the available randomized clinical trials comparing CTC and OC for CRC screening in asymptomatic patients...

PURPOSE: Although the majority of adult epilepsy patients respond well to the current antiepileptic drug treatment, 20-40% of them are drug-resistant. In these patients, resective epilepsy surgery is a curative treatment option, for which, however, only a limited number of patients is eligible. The purpose is to summarize the outcome of radiotherapy for drug-resistant non-neoplastic focal epilepsy and to elucidate its efficacy for seizure outcome and long-term toxicity in adults. METHOD: A systematic literature search was performed in Pubmed, Ovid Medline, Cochrane library, Embase and Web of Science...

Limited dispersal knowledge for most organisms hampers effective connectivity conservation in fragmented landscapes. In forest ecosystems, dead-wood dependent organisms (i.e. saproxylics) suffer from forest management and degradation globally. We review the empirical evidence on dispersal ecology of saproxylic insects and fungi. We focus on direct studies (e.g. mark-recapture, radio telemetry), field experiments and population genetic analyses. Our review revealed two somewhat opposite results: based on direct methods and experiments dispersal is limited within a few kilometers, whereas genetic studies generally find little genetic structure over tens of kilometers, indicating long-distance dispersal...

Colorectal cancer is associated with significant morbidity and mortality as many patients are diagnosed with advanced stage disease. MicroRNAs are small, non-coding RNA molecules which have a major role in gene expression regulation and are dysregulated in colorectal cancer. The miR-200 family is involved in epithelial-to-mesenchymal transition (EMT). This systematic review describes the roles of the miR-200 family in EMT in colorectal cancer. A search of electronic databases (PubMed and Embase) was conducted between January 2000 and July 2017...
