Distinct histopathological features at diagnosis of very early onset inflammatory bowel disease.

J Crohns Colitis 2018 Dec 14. Epub 2018 Dec 14.

The Children's Hospital of Philadelphia, Department of Pediatrics, Division of Gastroenterology, Hepatology, and Nutrition, Philadelphia, PA.

Background And Aims: Children with very early onset inflammatory bowel disease represent a unique cohort, often with a severe phenotype that is refractory to conventional medications, and in some cases, have underlying primary immunodeficiencies. Prior work has identified distinct histopathological patterns in the gastrointestinal tract in patients with primary immunodeficiencies. The aim of this study is to characterize the diagnostic histological findings in patients with VEO-IBD as compared to older onset pediatric IBD and determine if there are unique pathological changes that can shed light on the driving forces of the disease, particularly immunodeficiencies.

Ventilator-associated pneumonia: The central role of transcolonization.

J Crit Care 2018 Dec 6;50:155-161. Epub 2018 Dec 6.

Medical and Surgical Intensive Care Unit, Groupe Hospitalier Paris Saint Joseph, Paris, France; Endotoxins, Structures and Host Response, Department of Microbiology, Institute for Integrative Biology of the Cell, UMR 9891 CNRS-CEA-Paris Saclay University, 98190 Gif-sur-Yvette, France. Electronic address:

Ventilator-associated pneumonia remain frequent and serious diseases since they are associated with considerable crude mortality. Pathophysiology is centered on modifications of regional bacterial flora, especially tracheobronchial tree and oropharyngeal sphere. Bacterial migration from an anatomical area to another seems to be the main explanation of these alterations which are called "transcolonization". Read More

Alcohol and gastrointestinal cancers.

Curr Opin Gastroenterol 2018 Dec 12. Epub 2018 Dec 12.

Pancreato-Biliary Endoscopy Division and Endosonography Division, Pancreas Translational and Clinical Research Centre, San Raffaele Scientific Institute, Vita Salute San Raffaele University, Milan.

Purpose Of Review: Alcohol is a type I carcinogen and the WHO stated that it caused 5% of all deaths in 2016, of which 13% because of cancers. Among digestive tract cancers, this association is clear for esophageal, liver and colorectal cancer, and more debated for gastric and pancreatic cancer. The present review will revise recent evidence on epidemiologic association and mechanisms linking alcohol with the risk of esophageal, gastric, colorectal and pancreatic cancers. Read More

Artificial intelligence and upper gastrointestinal endoscopy: current status and future perspective.

Dig Endosc 2018 Dec 14. Epub 2018 Dec 14.

Graduate School of Informatics, Nagoya University, Nagoya, Japan.

With recent breakthroughs in artificial intelligence, computer-aided diagnosis (CAD) for upper gastrointestinal endoscopy is gaining increasing attention. Main research focuses in this field include automated identification of dysplasia in Barrett's esophagus and detection of early gastric cancers. By helping endoscopists avoid missing and mischaracterizing neoplastic change in both the esophagus and stomach, these technologies potentially contribute to solving current limitations of gastroscopy.

Asia Pac J Clin Oncol 2018 Dec 13. Epub 2018 Dec 13.

Department of Internal Medicine II, Osaka Medical College, Takatsuki, Osaka, Japan.

Aim: Gastric cancer patients are normally treated with oral fluoropyrimidine and cisplatin or oxaliplatin; however, treating patients who also have a gastrointestinal obstruction is often difficult because of their poor oral intake. Instead, a modified (m)FOLFOX-6 regimen is administered, even to patients with gastrointestinal obstructions. The aim of this study was to assess the efficacy of mFOLFOX-6 for gastric cancer patients with a gastrointestinal obstruction. Read More

Pharmacogenetics and prediction of adverse events in prescription opioid use disorder patients.

Basic Clin Pharmacol Toxicol 2018 Oct 29. Epub 2018 Oct 29.

Neuropharmacology on Pain (NED), Alicante Institute for Health and Biomedical Research (ISABIAL-FISABIO Foundation), Alicante, Spain.

The threats involved in the long-term opioid treatment of chronic non-cancer pain (CNCP) have increased notably. Strategies to identify at-risk patients are important because there is no clear evidence showing which screening or deprescription programmes are appropriate. Our aim was to evaluate the evidence provided by pharmacogenetics applied to predict an analgesic toxicity profile in prescription opioid use disorder (POUD) patients participating in an opioid deprescription programme.

Cancer Sci 2018 Dec 14. Epub 2018 Dec 14.

Department of Biomarkers for Early Detection of Cancer, National Cancer Center Research Institute, Tokyo, Japan.

Recently, there has been an increased attention to circulating tumor cells (CTCs) analysis, also known as liquid biopsy, owing to its potential benefits in cancer diagnosis and treatment. CTCs are released from primary tumor lesions into the blood stream and eventually metastasize to distant body organs. However, a major hurdle with CTC analysis is their natural scarcity. Read More

Subtyping of intraductal papillary mucinous neoplasms - pitfalls of MUC1 immunohistochemistry.

APMIS 2019 Jan 22;127(1):27-32. Epub 2018 Nov 22.

Department of Pathology, Copenhagen University Hospital Rigshospitalet, København, Denmark.

Intraductal papillary mucinous neoplasms (IPMNs) are precursor lesions of pancreatic ductal adenocarcinoma (PDAC). Current edition of WHO Classification of Tumors of the Digestive System recognizes four different subtypes (gastric, intestinal, pancreatobiliary, and oncocytic) and recommends analysis of mucin expression (MUC1, MUC2, MUC5AC, MUC6) as well as evaluation of architectural and cell differentiation patterns for correct classification. However, there is no consensus on MUC1 expression of IPMN-lesions in the literature. Read More

Front Oncol 2018 28;8:561. Epub 2018 Nov 28.

Department of Gastroenterology, University Hospital of North Norway, Tromsø, Norway.

The development of colorectal cancer (CRC) is not only determined by transformed cells , but also by factors existing in their immune microenvironment. Accumulating scientific evidence has revealed that interleukin (IL)-33, an IL-1 family member, plays an essential role in the regulation of immune response and is relevant in CRC pathogenesis. Data from both human and experimental studies demonstrated that IL-33 inhibits host anti-tumor immunity, remodels tumor stroma and enhances angiogenesis, thereby promoting the development of CRC.
