    Early the diagnosis, better the prognosis.

    The role of two polymorphisms rs1800591 and rs3816873 of the microsomal triglyceride transfer protein (MTTP) gene in the development of nonalcoholic fatty liver disease (NAFLD) remains controversial. A meta-analysis was conducted to determine the correlation between these MTTP polymorphisms and NAFLD.

    A systematic search was carried out using PubMed, Embase, and Cochrane Library to retrieve English studies that reported the relationship between MTTP polymorphisms (rs1800591 and rs3816873) and NAFLD published before February 18, 2020. Odds ratio (OR) and 95% confidence interval (CI) were used to appraise the risk of MTTP polymorphism in NAFLD.

    A total of 10 case-control studies, including 1388 cases and 1690 healthy subjects, were included. No significant correlation between the rs1800591 (G vs. T OR = 1.08, 95% CI = 0.68-1.70, P = 0.76) and rs3816873 (CT + CC vs. TT OR = 1.23, 95% CI = 0.76-2.01, P = 0.398) polymorphisms of MTTP and NAFLD was found in any of the models. However, when NASH patients confirmed by liver biopsy were extracted alone for rs1800591 polymorphism analysis, it was found that the G allele significantly increased the risk of NASH under the heterozygote model (GT vs. TT OR = 3.16, 95% CI = 1.13-8.83, P = 0.028) and dominant model (GT + GG vs. TT OR = 3.03, 95% CI = 1.13-8.09, P = 0.027).

    The present meta-analysis revealed that the rs1800591 and rs3816873 polymorphisms of the MTTP gene are uncommon in NAFLD. However, the G allele of rs1800591 was more likely to be correlated to NASH susceptibility.

    Acute pancreatitis (AP) is a commonly encountered emergency where early identification of complicated cases is important. Inflammatory markers like lymphocyte to monocyte ratio (LMR) and neutrophil to lymphocyte ratio (NLR) are simple and readily available markers. In this study, we evaluated the utility of these markers in the early identification of patients with complicated AP.

    All patients with a diagnosis of AP admitted to the University Medical Center in Las Vegas/Nevada between August 2015 and September 2018 were identified using ICD-10 codes. Medical records were reviewed retrospectively. Epidemiological measures and their associated confidence intervals were calculated using MedCalc (v. 18).

    The LMR showed a significant difference between groups, with the non-complicated cases consistently higher than the complicated cases but without significant temporal differences. The NLR showed a significant difference with a significant temporal relation. Tipranavir datasheet Using the bound of the 95% confidence interval separating the two groups, LMR <2 was found to be associated with a complicated case and NLR >10.5 was suggestive of a complicated case. High specificity (85-92%) with low sensitivity (23-69%) was noted; hence, these cut points were very good at discerning non-complicated cases.

    Our data show persistently low LMR that is associated with severe AP and a value of <2.0 can be used clinically to predict severe AP on admission. It also shows that elevated NLR is associated with complicated AP and prolonged hospital stay with a value >10.5 that can be used to predict severe complicated AP and to monitor response to treatment over time.

    A sufficiently open papilla is needed to remove common bile duct stones (CBDS) but endoscopic sphincterotomy (EST) requires a high level of skill and is difficult with endoscopic papillary balloon dilation (EPBD). The main adverse event of EST is bleeding and perforation and that of EPBD is post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis. To reduce these adverse events we employed minimal EST followed by papillary dilation (ESBD), and retrospectively evaluated its efficacy and safety compared with EST.

    CBDS patients who underwent EST (n = 114) or ESBD (n = 321) at Juntendo University Hospital from January 2009 to December 2018 were consecutively enrolled, retrospectively. The exclusion criteria were large-balloon dilation (≥ 12 mm), large CBDS (>12 mm), and previous EST/EPBD. We compared the overall stone removal rate, incidence of adverse event, procedure time, number of ERCP procedures, and rate of mechanical lithotripsy (ML) between the two groups.

    Complete stone removal was successful in both ESBD and EST group. However, the rate of multiple ERCP sessions was significantly lower (35.1% vs. 12.8%, P < 0.001), procedure time was shorter (31.6 vs. 25.8 min, P = 0.01), and rate of ML was lower (16.7% vs. 7.8%, P = 0.01) in ESBD group. Bleeding was significantly more frequent in the EST group (9.6% vs. 1.2%, P < 0.001), particularly acute bleeding (7.9% vs. 0.9%, P < 0.001).

    ESBD is more efficient and safer in the management of CBD stones than EST. A prospective randomized study comparing ESBD with EST is needed to establish this combination technique.

    This study aimed to design a structured simulation training curriculum for upper endoscopy and validate a new assessment checklist.

    A proficiency-based progression stepwise curriculum was developed consisting of didactic, technical and non-technical components using a virtual reality simulator (VRS). It focused on scope navigation, anatomical landmarks identification, mucosal inspection, retro-flexion, pathology identification, and targeting biopsy. A total of 5 experienced and 10 novice endoscopists were recruited. All participants performed each of the selected modules twice, and mean and median performance were compared between the two groups. Novices pre-set level of proficiency was set as 2 standard deviations below the mean of experts. Performance was assessed using multiple-choice questions for knowledge, while validated simulator parameters incorporated into a novel checklist; Simulation Endoscopic Skill Assessment Score (SESAS) were used for technical skills.

    The following VRS outcome measures have shown expert vs novice baseline discriminative ability total procedure time, number of attempts for esophageal intubation and time in red-out.
