A Novel Pre-Clinical Modeling of Massive Hemorrhagic Shock in Non-Human Primate: A Safe and Reproducible Method (Macaca fascicularis).

Background: Although non-human primates are the closest animals to humans to simulate physiological and metabolic responses, there is a paucity of primate hemorrhagic shock models that are standardized and reproducible. Herein, we describe a model that is a clinical replica of extreme class IV hemorrhagic shock with a step-by-step description of the procedure in cynomolgus macaque monkeys.

Methods: The physiological changes that occurred during the process were evaluated using hemodynamic parameters, echocardiogram, and laboratory values.

Monitoring Porcine Cytomegalovirus in Both Donors and Recipients is Crucial for Recipient's Survival in Pig-to-Cynomolgus Xenotransplantation.

Background: Xenotransplantation, particularly when involving pig donors, presents challenges related to the transmission of porcine cytomegalovirus (pCMV) and its potential impact on recipient outcomes. This study aimed to investigate the relationship between pCMV positivity in both donors and recipients and the survival time of cynomolgus monkey recipients after xenogeneic kidney transplantation.

Methods: We conducted 20 cynomolgus xenotransplants using 18 transgenic pigs.

Necessity of induction agent modification for old age kidney transplant recipients.

Background: Immunosenescence gradually deteriorates the function of the immune system, making elderly patients susceptible to infection, while reducing rejection of organ transplants. Therefore, age-adaptive immunosuppression is necessary in the elderly. We evaluated clinical outcomes such as rejection and infection rate when using basiliximab and rabbit anti-thymocyte globulin (r-ATG) as induction agents in elderly and young organ transplant recipients.

Laparoscopic versus open repeat liver resection for recurrent hepatocellular carcinoma in hepatectomy patients: inverse probability of treatment weighting.

Repeat liver resection (RLR) is a good treatment option for recurrent hepatocellular carcinoma (HCC). However, laparoscopic repeat liver resection (LRLR) is more technically demanding than open repeat liver resection (ORLR). The purpose of our study is to compare the surgical outcomes of ORLR and LRLR and to carefully present LRLR guidelines for HCC.

Two-Week Protocol Biopsy in Renal Allograft: Feasibility, Safety, and Outcomes.

Background: Protocol biopsy in renal allograft helps to early detect subclinical rejection (SCR) in patients who have no abnormal clinical and laboratory findings. Still, there are rare reports about the techniques and outcomes of two-week protocol biopsy. The aim of this study was to assess two-week protocol biopsy regarding the technical feasibility, procedure safety, and clinical outcomes.

Safety and effectiveness of kidney transplantation using a donation after brain death donor with acute kidney injury: a retrospective cohort study.

The use of kidneys from donation after brain death (DBD) donors with acute kidney injury (AKI) is a strategy to expand the donor pool. The aim of this study was to evaluate how kidney transplantation (KT) from a donor with AKI affects long-term graft survival in various situations. All patients who underwent KT from DBD donors between June 2003 and April 2016 were retrospectively reviewed.

Hepatocellular Carcinoma Arising from Hepatocellular Adenoma in an Elderly Male Patient.

Hepatocellular adenoma is a benign tumor of the liver occurring predominantly in young women taking oral contraceptives. The malignant transformation of hepatocellular adenoma into hepatocellular carcinoma has rarely been reported. Herein, we report the case of an elderly male patient with hepatocellular carcinoma that developed from hepatocellular adenoma.

Comparison of clinical outcomes of deceased donor kidney transplantations, with a focus on three induction therapies.

Background: Graft survival rate of kidney transplantation recipients improves after induction therapy. However, there is no conclusive evidence on which regimen is superior for deceased donor kidney transplantation (DDKT). This study aims at discussing effective induction therapy in DDKT.
