Impact of Hypothermic Perfusion on Immune Responses and Sterile Inflammation in a Preclinical Model of Pancreatic Transplantation.

Background: In organ transplantation, cold ischemia is associated with sterile inflammation that subsequently conditions adaptive immunity directed against the grafts during revascularization. This inflammation is responsible for venous thrombosis, which is the main postoperative complication affecting graft function. Our aim was to investigate the modulation of immune responses and endothelial function of pancreatic grafts during cold ischemia using different preservation modalities.

Pancreas Preservation: Hypothermic Oxygenated Perfusion to Improve Graft Reperfusion.

Background: The clinical standard for pancreas preservation for transplantation is static cold storage (SCS). Oxygenation during preservation has been shown to be advantageous in clinical studies. This study evaluates the efficiency of different oxygenation modalities during hypothermic pancreas preservation.

Background: SUNSHINE and SUNRISE demonstrated sustained clinical efficacy of secukinumab in patients with moderate-to-severe hidradenitis suppurativa (HS) through 52 weeks. Patients completing the core trials could enter a 4-year extension trial.

Objectives: To evaluate the long-term efficacy, safety/tolerability, and maintenance of clinical response of secukinumab through Week 104 in the extension trial.

Spontaneous Ischemic Cholecystitis in a Patient with Hereditary Hemorrhagic Telangiectasia (HHT).

Hereditary hemorrhagic telangiectasia (HHT) is an autosomal dominant disorder characterized by abnormal blood vessel formation, leading to recurrent epistaxis, cutaneous and mucosal telangiectases, and visceral arteriovenous malformations (AVMs). Hepatic involvement may result in complications such as high-output heart failure, portal hypertension, and biliary ischemia. We report an uncommon case of ischemic cholecystitis in a patient with HHT.

Allorecognition Unveiled: Integrating Recent Breakthroughs Into the Current Paradigm.

In transplantation, genetic differences between donor and recipient trigger immune responses that cause graft rejection. Allorecognition, the process by which the immune system discriminates allogeneic grafts, targets major histocompatibility complex (MHC) and minor histocompatibility antigens. Historically, it was believed that allorecognition was solely mediated by the recipient's adaptive immune system recognizing donor-specific alloantigens.

Urethral strictures post-hypospadias repair in adults.

Background: Urethral strictures post-hypospadias repair in adults is one of the most complex subjects in urethral reconstruction. Our goal is to provide an overview of the challenges encountered and the current treatment options.

Methods: A comprehensive literature review was conducted using PubMed for the period from 2020 to 2023.

Oxaliplatin-Based Versus Alkylating Agent in Neuroendocrine Tumors According to the O-Methylguanine-DNA Methyltransferase Status: A Randomized Phase II Study (MGMT-NET).

Purpose: Alkylating agents (ALKY) are the main chemotherapies used for advanced neuroendocrine tumors (NETs). O-Methylguanine-DNA methyltransferase (MGMT) status, as proficient (p) or deficient (d), may predict the response to ALKY.

Patients And Methods: MGMT-NET (ClinicalTrials.

Memory B Cells Provide Long-Term Protection to Vaccinated Kidney Transplant Recipients Against SARS-CoV-2 Variants.

Kidney transplant recipients (KTRs) are highly vulnerable to COVID-19. An intensified scheme of vaccination offers short-term protection to the 50%-75% of KTRs able to develop a germinal center reaction, required for the generation of neutralizing titers of antibodies (NAbs). However, the duration of this vaccinal protection is unknown.

Deciphering influence of donor age on adipose-derived stem cells: in vitro paracrine function and angiogenic potential.

Background: As fat grafting is commonly used as a filler, Adipose-derived stem/stromal cells (ASC) have been reported to be key player in retention rate. Paracrine and differentiation potential of those cells confer them strong pro-angiogenic capacities. However, a full characterization of the influence of aging on ASC has not been reported yet.

Insights from the BKEVER Trial comparing everolimus versus mycophenolate mofetil for BK Polyomavirus infection in kidney transplant recipients.

The MTOR inhibitors have demonstrated antiviral properties, and prior non-randomized studies have suggested they may have a suppressive effect on BKPyV replication. Here, in this randomized, multicenter, controlled trial (BKEVER study), we sought to evaluate the impact of everolimus (EVR) in facilitating the clearance of BKPyV compared to simply reducing immunosuppression among kidney transplant recipients (KTRs). All together, 130 KTRs presenting with BKPyV DNAemia were randomized 1:1 into two groups.

NK Cells: Not Just Followers But Also Initiators of Chronic Vascular Rejection.

Chronic graft rejection represents a significant threat to long-term graft survival. Early diagnosis, understanding of the immunological mechanisms and appropriate therapeutic management are essential to improve graft survival and quality of life for transplant patients. Knowing which immune cells are responsible for chronic vascular rejection would allow us to provide effective and appropriate treatment for these patients.
