Adverse Events after Percutaneous Transhepatic Biliary Drainage: A Ten-Year Retrospective Analysis.

Purpose: To determine the adverse events (AEs) rate associated with percutaneous transhepatic biliary drainage (PTBD) and identify risk factors for their occurrence.

Materials And Methods: This single-center retrospective study included 2310 PTBD (right-side: 1164; left-sided: 966; bilateral: 180) interventions for biliary obstruction (benign/malignant) in 449 patients between 2010-2020. Patients with percutaneous cholecystostomy alone were excluded.

Association of Neighborhood-Level Area Deprivation with Demographics and Outcomes in Oropharyngeal Squamous Cell Carcinoma.

Objective: To characterize neighborhood-level area deprivation's association with oropharyngeal carcinoma clinicodemographics, tumor staging, recurrence, and overall survival.

Study Design: Retrospective study.

Setting: Single institution academic medical center.

Cervicofacial emphysema: A systematic review.

Cervicofacial Emphysema (CFE) is a self-limiting condition, defined by the presence of air in face and neck. The purpose of the manuscript is to systematically review the existing literature on CFE evaluation and management for updated clinical understanding of this condition. A literature search was conducted of publications about CFE on PubMed and Google Scholar by identifying all the articles with key search terms "Cervicofacial Emphysema" and "Sub Cutaneous Emphysema".

Comparative Analysis of Displacements and Stress Produced by Square and Rectangular Bracket Slot With Incremental Torque: A Finite Element Analysis Study.

Introduction: This study aimed to perform a comparative analysis of stresses and displacements with incremental torque on the maxillary incisors and surrounding cortical bone using conventional metal brackets with rectangular slots and passive self-ligating brackets with square slots using finite element analysis (FEA).

Materials And Methods: An in vitro FEA study was conducted, in which a three-dimensional (3D) model of the maxilla was built using ANSYS software version 18 (ANSYS Inc., Canonsburg, PA).

A hierarchical reinforcement learning model explains individual differences in attentional set shifting.

Attentional set shifting refers to the ease with which the focus of attention is directed and switched. Cognitive tasks, such as the widely used CANTAB IED, reveal great variation in set shifting ability in the general population, with notable impairments in those with psychiatric diagnoses. The attentional and learning processes underlying this cognitive ability and how they lead to the observed variation remain unknown.
