Postoperative Outcomes of a Pelvic Pouch Procedure: Lessons Learned over 40 Years Among 5070 Patients.

Background: This study aims to report the experience over 40 years and outcomes of 5070 patients who underwent a pelvic pouch procedure.

Methods: A retrospective analysis of a prospectively maintained IPAA database- (1983 - 2022) was performed. Patients were stratified based on the diagnosis: ulcerative colitis (UC), indeterminate colitis (IC), familial adenomatous polyposis (FAP), inflammatory bowel disease-dysplasia, Crohn's colitis (CD), and others.

Segmental colectomy versus total proctocolectomy for ulcerative colitis: A systematic review and meta-analysis.

Aim: Total proctocolectomy (TPC) is the standard of care for patients with ulcerative colitis (UC) and dysplasia not amenable to endoscopic management. However, the risks of an extensive resection may outweigh the benefits in high-risk surgical patients. Therefore, we performed a systematic review and meta-analysis to assess postoperative outcomes between segmental colectomy (SEG) versus TPC in patients with UC.

Finite Element Model of Patient-Specific Flanged Acetabular Components Highlights Biomechanical Effects of Bone Density and Cortical Shell Thickness.

Patient-specific flanged acetabular components are utilized to treat failed total hip arthroplasties with severe acetabular defects. We previously developed and published a finite element model that investigated the impact of hip joint center lateralization on construct biomechanics during gait conditions. This model consisted of a patient-specific implant designed to address a superior-medial defect created in a standard pelvic geometry.

A Pooled Pharmacokinetic Analysis for Piperacillin/Tazobactam Across Different Patient Populations: From Premature Infants to the Elderly.

Background And Objectives: The pharmacokinetics (PK) of piperacillin/tazobactam (PIP/TAZ) is highly variable across different patient populations and there are controversies regarding non-linear elimination as well as the fraction unbound of PIP (f). This has led to a plethora of subgroup-specific models, increasing the risk of misusing published models when optimising dosing regimens. In this study, we aimed to develop a single model to simultaneously describe the PK of PIP/TAZ in diverse patient populations and evaluate the current dosing recommendations by predicting the PK/pharmacodynamics (PD) target attainment throughout life.
