Mediation analysis identifies causal factors that lead to increased rates of kidney transplant failure in patients with peripheral vascular disease.

Background: This study aims to identify causal mediators of one-year kidney transplant failure in patients with peripheral vascular disease.

Methods: Standard Transplant Analysis and Research database was queried for adults who underwent kidney transplantation from 1987 to 2021. Multi-organ transplant, prior transplant, and living donor kidneys were excluded.

A Novel Technique for Inguinal Hernia Repair in Patients With Nonmalignant Ascites.

Introduction: We report a novel approach to open inguinal hernia repair in patients with known ascites in which the cord, hernia sac, and attached testicle on the affected side are repositioned into the retroperitoneum through the inguinal ring. By avoiding invasion of the peritoneum and limiting dissection of the sac off the spermatic cord, the risk of ascites leak and testicular ischemia is theoretically decreased.

Methodology: This is a retrospective case series report.

Updated Appropriate Use Criteria for Amyloid and Tau PET: A Report from the Alzheimer's Association and Society for Nuclear Medicine and Molecular Imaging Workgroup.

The Alzheimer's Association and the Society of Nuclear Medicine and Molecular Imaging convened a multidisciplinary workgroup to update appropriate use criteria (AUC) for amyloid positron emission tomography (PET) and to develop AUC for tau PET. The workgroup identified key research questions that guided a systematic literature review on clinical amyloid/tau PET. Building on this review, the workgroup developed 17 clinical scenarios in which amyloid or tau PET may be considered.
