Islet transplantation is a potential treatment for Type 1 diabetes; however, improvements need to be made before it could become clinically widely available. In preclinical studies, the mouse is often used to model islet transplantation, with most studies aiming to improve transplantation outcome by manipulating the islets prior to transplantation or by treating the recipient mouse. Here, we describe the process of islet transplantation in the mouse, including how one can make the mouse diabetic, isolate donor islets, and transplant the islets into two different sites. Finally, we discuss how to assess the outcome of the transplantation in order to determine whether the experimental intervention has been beneficial.

Background/aims: Gestational Diabetes Mellitus (GDM), a prevalent complication in pregnancy, is characterized by the Diabetes Association as diabetes diagnosed in the second or third trimester, often remaining asymptomatic. This study investigates the intricate effects of Streptozotocin on pregnant rats, unraveling its impact on Gestational Type 2 Diabetes (GTD). The research delves into the potential therapeutic roles of mesenchymal stem cells (MSCs) and olive leaf extract (OLE) in mitigating the consequences of Streptozotocin-induced pancreatic impairment.

Islet transplantation is a promising therapy for diabetes, yet the limited survival and functionality of transplanted islet grafts hinder optimal outcomes. Glucagon-like peptide-1 (GLP-1), an endogenous hormone, has shown potential to enhance islet survival and function; however, its systemic administration can result in poor localization and undesirable side effects. To address these challenges, we developed a novel peptide-based nanofiber hydrogel incorporating GLP-1 functionality for localized delivery.

Objectives: To assess trends in surgical site infection (SSI) incidence in cardiosurgery following a quality improvement initiative in infection prevention and control (IP&C).
Methods: This is a historical cohort study encompassing a 10-year surveillance period (2014-2023) in a cardiosurgical department in a multi-organ transplant center. The study encompassed three periods: a baseline period (Phase_1: January 2014-December 2018); an implementation phase covering quality improvement initiatives targeting various aspects of IP&C including organizational factors, pre-operative, intra-operative, post-operative measures, and post-hospitalization care (Phase_2: January 2019-June 2021); a post-implementation phase (Phase_3: July 2021-September 2023).

Pancreatic islet transplantation is a promising cell replacement therapy for patients with type 1 diabetes (T1D), an autoimmune disease that destroys insulin-producing islet β cells. However, the shortage of donor pancreatic islets significantly limits the widespread use of this strategy as a routine therapy. Pluripotent stem cell-derived insulin-producing islet organoids present a promising alternative β cell source for T1D patients.

Xenotransplantation of porcine organs has made remarkable progress towards clinical application. A key factor has been the generation of genetically multi-modified source pigs for xenotransplants, protected against immune rejection and coagulation dysregulation. While efficient gene editing tools and multi-cistronic expression cassettes facilitate sophisticated and complex genetic modifications with multiple gene knockouts and protective transgenes, an increasing number of independently segregating genetic units complicates the breeding of the source pigs.
