Surgical Regret and Intraoperative Decision-Making: A Living Donor Kidney Case.

Surgical regret often experienced at times of a great loss may cause a surgeon to reflect on their practice and intraoperative decision-making. It is inevitable that in the surgical profession, both in training and practice, a surgeon's decisions will be questioned by themselves, peers, and possibly patients. Here, we explore a case of living donor kidney donation in which the surgeon chooses to discontinue the operation for an incidental finding.

Variability in surgical approaches to hernias in patients with ascites.

Background: Hernias in patients with ascites are common, however we know very little about the surgical repair of hernias within this population. The study of these repairs has largely remained limited to single center and case studies, lacking a population-based study on the topic.

Study Design: The Michigan Surgical Quality Collaborative and its corresponding Core Optimization Hernia Registry (MSQC-COHR) which captures specific patient, hernia, and operative characteristics at a population level within the state was used to conduct a retrospective review of patients with ascites undergoing ventral or inguinal hernia repair between January 1, 2020 and May 3, 2022.

Intra-axonal translation of Khsrp mRNA slows axon regeneration by destabilizing localized mRNAs.

Axonally synthesized proteins support nerve regeneration through retrograde signaling and local growth mechanisms. RNA binding proteins (RBP) are needed for this and other aspects of post-transcriptional regulation of neuronal mRNAs, but only a limited number of axonal RBPs are known. We used targeted proteomics to profile RBPs in peripheral nerve axons.

Introduction to the Best-Case/Worst-Case Framework Within Transplantation Surgery to Improve Decision-Making for Increased Risk Donor Organ Offers.

Public Health Service increased risk donor kidneys are discarded 50% more often than nonincreased risk donor kidneys despite equivalent patient and graft survival outcomes. Patient and provider biases as well as challenges in risk interpretation contribute to the underuse of increased risk donor organs. As the ultimate decision to accept or reject an increased risk donor organ results from the patient-provider conversation, there is an opportunity to improve this dialogue.

Fostering Passion and Skills in Surgical Research Across the Medical Education Continuum: The Transplant Research, Education, and Engagement Group.

Objective: We describe a multilevel, collaborative research group for trainees and faculty engaging in transplant surgery research within one institution.

Design: Transplant Research, Education, and Engagement (TREE) was designed to develop trainees' research skills and foster enthusiasm in transplant surgery along the educational continuum. Our research model intentionally empowers junior researchers, including undergraduates and medical students, to assume active roles on a range of research projects and contribute new ideas within a welcoming research and learning environment.

C9orf72 Poly(PR) Dipeptide Repeats Disturb Biomolecular Phase Separation and Disrupt Nucleolar Function.

Repeat expansion in the C9orf72 gene is the most common cause of the neurodegenerative disorder amyotrophic lateral sclerosis (C9-ALS) and is linked to the unconventional translation of five dipeptide-repeat polypeptides (DPRs). The two enriched in arginine, poly(GR) and poly(PR), infiltrate liquid-like nucleoli, co-localize with the nucleolar protein nucleophosmin (NPM1), and alter the phase separation behavior of NPM1 in vitro. Here, we show that poly(PR) DPRs bind tightly to a long acidic tract within the intrinsically disordered region of NPM1, altering its phase separation with nucleolar partners to the extreme of forming large, soluble complexes that cause droplet dissolution in vitro.
