Cost-Benefit Analysis of Various Management Algorithms for Suspected Choledocholithiasis.

The goal of our study is to evaluate the safest, efficient, and most cost-effective way to manage suspected choledocholithiasis. This retrospective study evaluated adult patients with suspected choledocholithiasis based on labs and imaging at a single institution between 2017 and 2022 and characterized them into 1 of 3 groups based on their management pathway: (1) ERCP-first, (2) MRCP-first, or (3) surgery-first with possible intraoperative cholangiogram pending laboratory trend. Our primary outcome was hospital length of stay.

A non-intrusive reduced-order model for finite element analysis of implant positioning in total hip replacements.

Sophisticated high-fidelity simulations can predict bone mass density (BMD) changes around a hip implant after implantation. However, these models currently have high computational demands, rendering them impractical for clinical settings. Model order reduction techniques offer a remedy by enabling fast evaluations.

A systematic assessment of robustness in CNS safety pharmacology.

Background And Purpose: Irwin tests are key preclinical study elements for characterising drug-induced neurological side effects. This multicentre study aimed to assess the robustness of Irwin tests across multinational sites during three stages of protocol harmonisation. The projects were part of the Enhanced Quality in Preclinical Data framework, aiming to increase success rates in transition from preclinical testing to clinical application.

Subcutaneous Administration of a Monoclonal Antibody to Prevent Malaria.

Background: Subcutaneous administration of the monoclonal antibody L9LS protected adults against controlled infection in a phase 1 trial. Whether a monoclonal antibody administered subcutaneously can protect children from infection in a region where this organism is endemic is unclear.

Methods: We conducted a phase 2 trial in Mali to assess the safety and efficacy of subcutaneous administration of L9LS in children 6 to 10 years of age over a 6-month malaria season.

Evidence-based comparative severity assessment in young and adult mice.

In animal-based research, welfare assessments are essential for ethical and legal reasons. However, accurate assessment of suffering in laboratory animals is often complicated by the multidimensional character of distress and pain and the associated affective states. The present study aimed to design and validate multidimensional composite measure schemes comprising behavioral and biochemical parameters based on a bioinformatics approach.
