Transplanted lung allografts are particularly susceptible to infection among SOT due to the constant exposure to the environment, aggressive immunosuppressive strategies, and impaired clearance mechanisms after denervation of the transplanted lung. Though prophylactic antimicrobial, antifungal, and antiviral regimens are used as preventive strategies to mitigate the risk of infection, complications related to allograft infection remain one of the primary causes of morbidity and mortality after lung transplantation.

Despite the concerted efforts by lung transplant recipients (LTR) and their medical teams, hospital readmissions are common in the first year following transplantation. Reasons for unplanned readmissions include allograft rejection, infections, and respiratory failure before the SARS-COV-2 pandemic. Clinical predictors of readmissions have changed over time with the higher risk factors of acceptable criteria for recipients and donors. We aimed to assess more recent readmission rates based on group classifications t [...]

Lung Transplant Recipients (LTR) are particularly vulnerable to severe infection, hospitalization, and death due to community acquired respiratory viruses. As a result, the global SARS-Cov-2 pandemic poses a higher risk to this population. We aim to study the lung function, severity of infection and mortality among LTR at a single center. A retrospective chart review was performed on all LTR at the University of San Diego, California Medical Center between June 2020 and September 2022. Spirometry was performed at 1 [...]

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 [...]
