Azathioprine and risk of non-melanoma skin cancers in organ transplant recipients: a systematic review and update meta-analysis.
Clin Transl Oncol
January 2025
Anhembi University Morumbi, São José dos Campos, São Paulo, 12235-181, Brazil.
Background: Immunosuppression might increase the risk of skin cancer in organ transplant recipients (OTRs), with azathioprine (AZA), exerting a fundamental role in the carcinogenesis of those tumors. This systematic review and meta-analysis aims to address the risk of developing malignant skin neoplasms in OTRs undergoing immunosuppression with AZA.
Methods: PubMed, Cochrane and Embase were searched for studies with OTRs who have a treatment regimen involving Azathioprine therapy after transplantation and that analyzed the emergence of skin neoplasia.
Use of Brain Death Recipients in Xenotransplantation: A Double-Edged Sword.
Xenotransplantation
January 2025
Beijing Key Laboratory of Preclinical Research and Evaluation for Cardiovascular Implant Materials, Animal Experimental Centre, National Centre for Cardiovascular Disease, Department of Cardiac Surgery, Fuwai Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing, China.
Organ transplants are used to treat many end-stage diseases, but a shortage of donors means many patients cannot be treated. Xenogeneic organs have become an important part of filling the donor gap. Many current studies of kidney, heart, and liver xenotransplantation have used gene-edited pig organs on brain-dead recipients.

Xenotransplantation
January 2025
Department of Surgery, University of Maryland School of Medicine, Baltimore, Maryland, USA.
Advancements in xenotransplantation intersecting with modern machine perfusion technology offer promising solutions to patients with liver failure providing a valuable bridge to transplantation and extending graft viability beyond current limitations. Patients facing acute or acute chronic liver failure, post-hepatectomy liver failure, or fulminant hepatic failure often require urgent liver transplants which are severely limited by organ shortage, emphasizing the importance of effective bridging approaches. Machine perfusion is now increasingly used to test and use genetically engineered porcine livers in translational studies, addressing the limitations and costs of non-human primate models.

Xenotransplantation
January 2025
Institute of Organ Transplantation, Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology, Wuhan, China.
Background: Gene-edited pigs for xenotransplantation usually contain one or more transgenes encoding human complement regulatory proteins (CRPs). Because of species differences, human CRP(s) expressed in gene-edited pigs may have difficulty inhibiting the activation of exogenous rabbit complement added to a complement-dependent cytotoxicity (CDC) assay. The use of human complement instead of rabbit complement in CDC experiments may more accurately reflect the actual regulatory activity of human CRP(s).

Department of General and Laparoscopic Surgery, Sheikh Khalifa Bin Zayed Al-Nahyan Hospital Muzaffarabad, Azad Jammu and Kashmir, Pakistan.
Objective: To determine the importance of the Glasgow Coma scale (GCS), ASA physical status classification system, and P-POSSUM score in predicting mortality among patients undergoing emergency laparotomies.
Study Design: An analytical study. Place and Duration of the Study: Department of General Surgery, Sheikh Khalifa Bin Zayed Al-Nahyan Hospital Muzaffarabad, Pakistan, from October 2020 to January 2022.
