There has been a steady expansion in islet isolation and transplantation activity worldwide. In addition to preparing human islets for transplantation, we have been providing human islets to basic researchers. The aim of this study was to review the activity of distribution of human islets to basic researchers in North America, Europe, and Asia, and to investigate if there are any differences in utilization rate of islets among three continents. We reviewed our islet isolation batch files, donor records, and docume [...]

Thrombotic Microangiopathy (TMA) is a syndrome characterized by microangiopathic hemolytic anemia (MAHA) and thrombocytopenia. The presence of schistocytes on peripheral smear, a negative Coombs test, elevated lactate dehydrogenase, increased reticulocyte count and low haptoglobin are often the clues for MAHA. The microvascular process often targets vasculature in kidneys, brain, gastrointestinal system, heart, and skin. A timely diagnosis and treatment are often crucial to prevent severe end organ damage and death [...]

With the progressive rise in rates of liver transplantation, stagnant donor pool, and social factors, living donor liver transplantation (LDLT) forms the majority of liver transplantations performed in Asian countries. As the global prevalence of metabolic-associated fatty liver disease (MAFLD) is increasing, around 17-25% of all the prospective donors turn out to be steatotic at the time of evaluation and, as such, rejected for donor hepatectomy, thereby considerably reducing the living donor pool. Steatotic graft [...]

Lung transplantation in patients with end stage lung disease can improve survival and quality of life. Airway complication incidence varies between 2-33%, but the true incidence is difficult to determine due to a lack of validated classification systems. There are many risk factors for post lung transplant airway complications, the most common being anastomotic ischemia, pulmonary infections, surgical technique and allograph dysfunction. Common complications include formation of granulation tissue, anastomotic sten [...]

Human Leucocyte Antigens (HLA) constitute a highly polymorphic set of genes pivotal to the immune response. The HLA heterozygous advantage hypothesis assumes that heterozygous individuals at the HLA level have a wider range of peptides for T cell recognition than homozygous individuals. Consequently, they possess an enhanced capacity to trigger a targeted immune reaction. The divergent allele advantage hypothesis is an extension of heterozygous advantage, considering the excessive sequence divergence between allele [...]

Chronic allograft dysfunction (CLAD) is one of the leading causes of death after lung transplantation [1]. CLAD is a progressive and irreversible decline in lung function after transplant, manifested as an obstructive, restrictive, or mixed ventilatory impairment without any identifiable etiology as infection or acute rejection. Multiple risk factors have been associated with this condition. Despite its significant effect on the mortality of transplanted patients, there is still a lack of powerfully effective thera [...]

Malnutrition remains a clinical challenge in AML patients undergoing autologous hematopoietic stem cell transplantation (ASCT), leading to physical deconditioning and prolonged hospitalization. Prospective data are mainly lacking to identify those patients who may particularly benefit from parenteral nutrition in this setting. This observational, non-randomized, retrospective, exploratory cohort study assessed the nutritional development in patients following high-dose chemotherapy (HDCT) with ASCT and explored the [...]

SARS-CoV-2 infection has significantly impacted solid organ transplant (SOT) recipients, who are at high risk of disease and worse outcomes. Moreover, therapeutic management in this population is not precise yet. Our study aimed to evaluate the overall survival of SOT recipients and predictive factors for mortality. We also aimed to assess the impact of antiviral treatments and immunosuppressant changes on overall mortality and to evaluate the length of hospital stay of SOT compared to the general population. This [...]

The shortage of donor lungs for transplantation is a major challenge, resulting in longer waitlist times for patients with a higher risk of waitlist mortality. It is crucial to continue promoting awareness about organ donation through legislation, public campaigns, and health care provider education. Only a small number of cadaveric donors meet the ideal criteria for lung donation, leaving many lungs unused. Donor lung utilization can be improved by carefully considering the extended-criteria donors, actively parti [...]
