Rupture of intrahepatic bile duct after ERCP for common bile duct stone: A case report of rare complications.

Rationale: Complications after endoscopic retrograde cholangiopancreatography (ERCP) are diverse and usually treated with nonoperative management or percutaneous drainage; however, there are still some rare, life-threatening complications. This is an extremely rare case of biliary peritonitis caused by rupture of the intrahepatic bile duct after ERCP.

Patient Concerns: A 63-year-old male underwent ERCP for common bile duct stones.

Comparing Artificial Intelligence-Based Versus Conventional Endotracheal Tube Monitoring Systems in Clinical Practice.

Endotracheal tube dislodgement is a common patient safety incident in clinical settings. Current clinical practices, primarily relying on bedside visual inspections and equipment checks, often fail to detect endotracheal tube displacement or dislodgement promptly. This study involved the development of a deep learning, artificial intelligence (AI)-based system for monitoring tube displacement.

A high-performance method for quantitation of aflatoxins B1, B2, G1, G2: Full validation for raisin, peanut matrices, and survey of related products at Ho Chi Minh City.

Optimization and validation for simultaneous quantitation of four aflatoxins B1, B2, G1, and G2 in peanuts and raisins were performed on ultra-performance liquid chromatography in a combination of fluorescence detector, without derivatization. The advantages were short analysis time, simple sample handling, and reduced solvent consumption. Instrument detection limits of AFB1, AFB2, AFG1, and AFG2 were 0.

Impact of the COVID-19 Pandemic on the Severity and Early Postoperative Outcomes of Acute Appendicitis.

Background The coronavirus disease 2019 (COVID-19) pandemic caused changes in surgical practice. For acute appendicitis (AA), measures to control the pandemic might hinder patients from seeking medical care timely, resulting in increasing severity, postoperative complications, and mortality. This study aimed to investigate whether the COVID-19 pandemic had a negative impact on the severity and postoperative outcomes of patients with AA.

Vietnam's success story against COVID-19.

Vietnam's close proximity to China where the COVID-19 outbreak started made it one of the countries expected to have widespread transmission of the virus. However, the country opposed this expectation and attained low spread of COVID-19 infection due to its proactive approaches in containing the disease. As of March 11, 2021, Vietnam has a total of 2529 confirmed cases, equivalent to 26 cases per one million population-compared to the global rate of 15,223 cases.

Statistical tests of demographic heterogeneity theories.

In this paper we develop predictions from models of life-long demographic heterogeneity. These predictions are then compared to observations of mortality in large laboratory populations of Drosophila melanogaster. We find that the demographic heterogeneity models either require levels of variation that far exceed what would be considered biologically plausible, or they predict a much larger number of very old individuals than we actually observe.

The First Six-Membered "True" Heterocycle - Hydrogen-Bond-Assisted Ladder Formation in a KOCNPS Ring System.

A ladder of alternating K S and K O rings exists in K[Ph P(S)NC(O)Ph]⋅MeOH, the first six-membered "true" heterocycle, in the solid state (see picture). A simple P-N bond-forming reaction between benzamide and Ph PCl gives the precursor Ph P(S)NHC(O)Ph, from which the potassium salt can be generated by reaction with KOtBu.
