Application of Big Data analysis in gastrointestinal research.

Application of Big Data analysis in gastrointestinal research. World J Gastroenterol. 2019 Jun 28;25(24):2990-3008 Authors: Cheung KS, Leung WK, Seto WK Abstract Big Data, which are characterized by certain unique traits like volume, velocity and value, have revolutionized the research of multiple fields including medicine. Big Data in health care are defined as large datasets that are collected routinely or automatically, and stored electronically. With the rapidly expanding volume of health data collection, it is envisioned that the Big Data approach can improve not only individual health, but also the performance of health care systems. The application of Big Data analysis in the field of gastroenterology and hepatology research has also opened new research approaches. While it retains most of the advantages and avoids some of the disadvantages of traditional observational studies (case-control and prospective cohort studies), it allows for phenomapping of disease heterogeneity, enhancement of drug safety, as well as development of precision medicine, prediction models and personalized treatment. Unlike randomized controlled trials, it reflects the real-world situation and studies patients who are often under-represented in randomized controlled trials. However, residual and/or unmeasured confounding remains a major concern, which requires meticulous study design and various statistical adjustment methods. Other potential drawbacks include data validi...

This study aims to explore the effects of GP extracts on alleviating non-alcoholic fatty liver disease (NAFLD). In this experiment, C57BL/6 J mice were randomly assigned into normal diet control (ND), HFHC (high-fat and high-cholesterol) and HFHC + GP (GP) groups. Mice in HFHC group were fed HFHC diet combined with fructose drinking water for 12 weeks to induce the animal model of NAFLD, followed by ordinary drinking water until the end of the experiment. In the HFHC + GP group, mice were fed HFHC diet combined with fructose drinking water for 12 weeks, followed by GP-containing drinking water till the end. Mouse...

Authors: Waluga M, Kukla M, Kotulski R, Zorniak M, Boryczka G, Kajor M, Ciupinska-Kajor M, Lekstan A, Olczyk P, Waluga E Abstract Omentin and vaspin are adipokines potentially considered in the development of liver pathology. Irisin is new myokin potentially participating in energy processes in the organisms. The aim of this study was to evaluate the plasma concentration of these cytokines and the relationships of them with selected parameters of laboratory tests and of histopathological changes in selected chronic liver diseases: non-alcoholic fatty liver diseases (NAFLD), primary biliary cholangitis (PBC) and alc...

A 53-year-old male with a history of alcoholic liver cirrhosis presented with hematemesis. Emergency endoscopic examination revealed a huge gastric varix with stigmata at the fundus. Hemostasis was achieved through endoscopic variceal obliteration using a mixture of N-butyl-2-cyanoacrylate (1cc) and lipiodol (1cc) injection three times for hemostasis at a single session. Post-procedural X-ray revealed radiopaque materials. Sequential computed tomography of the abdomen revealed acute obstruction of the portal system with the injected mixture (Fig.

ConclusionsRoutine intraoperative liver biopsy during adolescent bariatric surgery possesses questionable benefit, as it does not appear to impact short-term postoperative management. Prospective, longitudinal studies are needed to better understand the meaningfulness of liver histopathology in this population.

Objectives: The aim of the study was to determine whether pediatric patients with nonalcoholic fatty liver disease (NAFLD) exposed to psychotropic medications have more severe liver disease compared to their counterparts who are not on these medications. We hypothesize that use of psychotropic agents is associated with liver disease severity. Methods: Children and adolescents with biopsy-confirmed NAFLD were included in this study. Histology data, detailed clinical information, and results of serum biochemistries performed within 3 months of the liver biopsy were collected retrospectively. Univariate and multivariate ...

Conclusions: Liver US patterns in children with CF correlate with platelet count, spleen size and indices of liver fibrosis. Multivariable models of these biomarkers have excellent discriminating ability for NL versus NOD, and good ability to distinguish other US patterns, suggesting that US patterns correlate with clinically relevant liver disease.

Background and Aims: The aim of the study was to aid decisions on prognosis and transplantation; this study describes the outcome of children with intestinal failure managed by the multidisciplinary intestinal rehabilitation program at the Royal Children's Hospital, Melbourne. Methods: Retrospective review of children requiring parenteral nutrition (PN) for>3 months who were assessed for home PN between 1991 and 2011. Results: A total of 51 children were included. Forty-two (82%) had short bowel syndrome (SBS), 5 (10%) had chronic intestinal pseudo-obstruction syndrome, and 4 (8%) had congenital enteropathies. M...

This study aimed to determine the prognostic role of the categorized hemodynamic stage (HS) based on the hepatic venous pressure gradient (HVPG) in patients with portal hypertension. METHODS: Of 1,025 cirrhotic patients who underwent HVPG measurement, data on 572 non-critically-ill patients were collected retrospectively between 2008 and 2013. The following two HS categorizations were used: HS-1 (6-9, 10-12, 13-16, 17-20, and> 20 mmHg; designated as groups 1-5, respectively) and HS-2 (6-12, 13-20, and> 20 mmHg). Clinical characteristics, mortality rates, and prognostic predictors were analyzed according to the c...
