Abstract Colorectal cancer is a major health problem, where advances towards computer-aided diagnosis (CAD) systems to assist the endoscopist can be promising path improvement. Here, deep learning model for real-time polyp detection based on pre-trained YOLOv3 (You Only Look Once) architecture and complemented with post-processing step an object-tracking algorithm reduce false positives reported. The base network was fine-tuned using dataset composed of 28,576 images labelled locations 941...
Intrahepatic cholestasis of pregnancy (ICP) is characterized by pruritus and elevated bile acid concentrations in maternal serum. This accompanied an enhanced risk intra-uterine perinatal complications. High sulphated progesterone metabolites (PMS) have been suggested to be involved the multifactorial aetiopathogenesis ICP. The aim this study was investigate further mechanism accounting for beneficial effect oral administration ursodeoxycholic (UDCA), which standard treatment, regarding PMS...
Background PolyDeep is a computer-aided detection and classification (CADe/x) system trained to detect classify polyps. During colonoscopy, CADe/x systems help endoscopists predict the histology of colonic lesions. Objective To compare diagnostic performance expert for optical diagnosis colorectal polyps on still images. Methods Image Classification (PIC) an in vitro test study. The PIC database contains NBI images 491 with histological diagnosis. We evaluated four neoplasia (adenoma,...
Lynch syndrome (LS) is a common cause of hereditary colorectal cancer (CRC). Some CRC patients develop mismatch repair deficiency without germline pathogenic mutation, known as Lynch-like (LLS). We compared the risk in first-degree relatives (FDRs) LLS and LS patients. was diagnosed when tumors showed immunohistochemical loss MSH2, MSH6, PMS2; or MLH1 with BRAF wild type; and/or no methylation absence mutation these genes. other LS-related neoplasms were followed among their FDRs....
The aim of this study was to evaluate the efficacy endoscopic band ligation (EBL) in carefully selected patients who would benefit from method resection.Patients with early upper gastrointestinal and small (< 15 mm) lesions treated EBL (Duette® Multi-Band Mucosectomy) were prospectively recruited retrospectively analyzed between 2010 2015. All cases discussed a multidisciplinary cancer committee it concluded that, owing patient conditions, surgery not possible that conducting histology...
A 73-year-old man underwent a total gastrectomy plus splenectomy for gastric adenocarcinoma (T3N1M0). At the early postoperative stage, patient presented an esophagojejunostomy leak (> 1 cm diameter; [Fig. a]). Medical management and endoscopic treatment were considered first. customized, partially covered biodegradable stent ([Fig. b]) (Ella Stent; ELLA-CS, Hradec Kralove, Czech Republic; diameter 31/25/31 mm, length 110 mm) was successfully placed under fluoroscopic guidance 5 weeks after...
Lynch syndrome (LS) families have a high risk of colorectal cancer (CRC) development. Colonoscopy every < 3 years decreases CRC incidence and mortality. However, recent studies show that up to 40% develop during colonoscopy follow-up. Our aim is assess the clinic-pathological, genetic endoscopy quality measures are predictors surveillance in LS carriers.
Aims 1) To assess the efficacy of an online self-learning tool for OD diminutive colorectal polyps; 2) describe in detail learning process and possible variables related to efficacy.
Aims To assess the effect of quality endoscopic factors on development PCCRC during surveillance in LS mutation carriers.
Several new studies published over the past decade have demonstrated a link between ambient air pollution and several adverse effects on human health even at lower c,o,ncentrations typically observed in North America Europe today, suggesting that may posh risk to public health, The of gaseous pollutants, such as ozone, nitrogen oxides, sulphur dioxide, carbon monoxide, are not wel established. Our study set out determine possible relations variations pollutants mortality city Salamanca...
