BACKGROUND: Understanding COVID-19 vaccine hesitancy in organ transplant recipients (OTRs) is critical given clear-albeit attenuated-benefits from vaccination. METHODS: Adult OTRs were surveyed regarding sociodemographic data, medical history, and vaccine-related values. A novel outcome variable called the Vaccine Acceptance Composite Score (VACS) was built as the average Likert score of seven domains of vaccine confidence. To examine its association with several factors and individual adherence to COVID-19 vaccine recommendations, univariable odds ratios and relative operating characteristic areas under the curve (AUC) values were calculated...

OBJECTIVE: To explore the clinical application value of flow-through anterolateral thigh perforator (ALTP) flaps in replantation of complex severed limbs. METHODS: Thirteen severe vascular, nerve injury, and skin or soft tissue defects in patients with complex severed limbs from August 2017 to January 2019 were enrolled in this retrospective study. The skin flap has covered the wound by using the flow-through ALTP flap technique. The main vascular defect was repaired by using the descending branch of the lateral circumflex femoral artery, and the blood supply of the transplanted limb was reconstructed...

Kaposi's Sarcoma (KS) is a malignant vascular tumor commonly seen in immunocompromised individuals, particularly patients with acquired immunodeficiency syndrome. Lung transplant recipients are at high risk of developing KS due to a strong immunosuppressive regimen that can lead to donor-derived infection or reactivation of recipient human herpesvirus 8, the causative organism for KS. In this overview, we describe 2 lung transplant recipients who developed pulmonary KS with poor outcomes, reviewing the diagnosis, bronchoscopy findings, and treatment and surveillance strategies for pulmonary KS...

To resolve the critical donor shortage worldwide, enlarging the potential donor pool to include expanded criteria donors is necessary. Despite numerous attempts to establish new preservation solutions, no dramatic innovation has occurred since University of Wisconsin (UW) solution displaced Euro Collins' solution; UW solution remains the global gold standard. We previously developed a heavy water (D2 O)-containing organ storage solution, Dsol, which is effective for livers subjected to extended cold storage (CS), and reported its effectiveness...

BACKGROUND: The early detection of myeloid engraftment after hematopoietic stem cell transplantation (HSCT) is of clinical importance for clinicians. In this study, we evaluated whether serum lactic dehydrogenase enzyme levels are significant predictors in the early detection of successful myeloid engraftment after HSCT. METHODS: The study included 74 patients, all of whom underwent HSCT between February 2014 and June 2020. Serum lactic dehydrogenase (LDH) enzyme and complete blood parameters were evaluated at the start of the preparation regimen, on the day of product infusion, 5 days before myeloid engraftment, on the day of myeloid engraftment, and 5 days after engraftment...

Quality of life (QoL) is a vital aspect of postdonation amongst donors, especially elderly donors. There is a limited study from India assessing the QoL amongst young live donors (YLD), and no study has been done on the elderly sub-group. This study was undertaken to determine the donors' sociodemographic and essential clinical characteristics, as well as to study the QoL of the live kidney donors and compare the QoL of elderly and young donors. Baseline demographic characters taken from the RTR registration register and SF-36 questionnaire were used to assess the QoL at baseline, discharge post-transplant, 1 month, 3 months, 6 months, and 12 months through an interview...

OBJECTIVE: To explore the effect of enhanced recovery after surgery nursing on the recovery in patients after liver transplantation. METHODS: This study was performed in 128 patients underwent liver transplantation in our hospital. According to the random number table, these patients were divided into the control group (n = 64) and the experimental group (n = 64). Patients in the control group received traditional nursing, while those in the experimental group received enhanced recovery after surgery nursing...

BACKGROUND: Disparity in waiting time to kidney transplantation led to new policy (KAS250). Our aims were to identify variables associated with long wait time (LWT); assess the impact of KAS250 on WT; and analyze modifiable transplant center behaviors correlated with WT. METHODS: SRTR data for adult deceased donor kidney transplants were analyzed. Time-periods from 8/1/2018-7/31/2019 and 5/1/2021-4/30/2022 were chosen for pre- and post-KAS250 analyses. Transplant centers were categorized as LWT or SWT centers depending on whether pre-KAS250 median center waiting times were greater or less than the national pre-KAS250 median waiting time of 57...

We present a challenging case of Epstein-Barr virus-related isolated small bowel post-transplant lymphoproliferative disorder (PTLD) in a pediatric heart transplant recipient presenting as recurrent gastrointestinal (GI) bleeding and subsequently a GI fistulous tract with associated intra-abdominal abscess. Diagnosis was not confirmed until exploratory laparoscopy was performed, with excision of the fistulous tract revealing evidence of PTLD on pathology. Early diagnosis of GI-PTLD remains a challenge, especially if isolated in the small intestine...

BACKGROUND: Heart transplantation (HT) recipients are at risk for urgent rehospitalizations following discharge. However, data on prevalence, risk factors and clinical outcomes associated with post-HT rehospitalization are limited. METHODS: This study aims to describe patterns of urgent rehospitalizations in HT recipients at a cardiology reference center in Brazil. Rehospitalizations and deaths occurring within the first 90 days following hospital discharge were identified...

BACKGROUND: Medication nonadherence (MNA) in organ transplant recipients is associated with increased risk of rejection, allograft loss, patient death, and higher healthcare costs. Various approaches have been used in an attempt to reduce MNA. A patient support program (PSP) can be an invaluable tool for improving patient outcomes. The aim of this study was to analyze available data of PSP for kidney transplant recipients. METHODS: A total of 3352 patients from all over the country were prospectively enrolled in the Parichay PSP between January 2021 and April 2023...

OBJECTIVE: The aim of this study was to observe the recovery of liver function in patients with early allograft dysfunction (EAD) at one month postoperatively and explore whether early postoperative ultrasonic hemodynamic parameters can predict this outcome. METHODS: Patients with EAD postoperatively, who underwent orthotopic liver transplantation (OLT) in our hospital from December 2012 to June 2021, were retrospectively collected. Based on the recovery of liver function within one month, patients were divided into two groups: the recovery group (FR-1M) and the non-recovery group (Non-FR-1M)...

BACKGROUND: China experienced one of the largest spikes in COVID-19 several months ago, followed by multiple rounds of reinfections. COVID-19 predisposes to the development of acute kidney injury (AKI) which has a higher developing risk in organ transplant recipients. However, few studies reported multiple infections and changes in renal function in the kidney transplant population in China. METHOD: We followed up the patients who underwent kidney transplantation who completed our questionnaire at the initial spike of the epidemic and analyzed their infections and changes in renal function and analyzed the factors affecting the changes in renal function...

BACKGROUND AND OBJECTIVE: Organ donation is a procedure in which an organ is surgically removed from a human to be transplanted into another. The need for organ transplantation is increasing with time, and thus, the gap in the awareness of organ donors about the process must be recognized. This study aims to raise awareness and perceptions regarding organ donation and transplantation among the adult population. METHODS: Between May 2021 and April 2022, we conducted an analytical cross-sectional study involving residents of Bisha...

BACKGROUND: The mismatch between the number of patients awaiting kidney transplantation and the supply of donor organs has contributed to the increase in kidney transplantation from donors after circulatory death (DCD). Persistently long waiting times have led the transplant community to continue to explore the use of expanded- criteria DCD kidneys. In parallel, advances in organ preservation strategies have contributed to an overall increase in DCD organ transplantation and are altering the transplant landscape...

Late recurrence of hepatocellular carcinoma (HCC) following orthotopic liver transplant (OLT) is infrequently reported, and among cases, those isolated to the spine are rare. Prognoses are poor for this patient population, and no work has been undertaken to create uniform guidelines for management. Here, we report two cases of late recurrent HCC to the spine after OLT and favorable survival outcomes following intervention.

BACKGROUND: Complications and comorbidities that may develop after living donor liver transplantation may necessitate rehospitalization after discharge. We aimed to investigate the demographic and clinical factors affecting rehospitalization after discharge. METHODS: Two hundred seventy patients who underwent living-donor liver transplantation (LDLT) for end-stage liver cirrhosis were included in the study. Patients were divided into two groups as readmission group and others for statistical analysis...

BACKGROUND: Sarcopenia's impact on post-liver transplant outcomes remains a subject of debate, with limited data from South Asia on its association with post-liver transplant hospital stays. This study aims to investigate sarcopenia's influence on post-transplant hospitalization duration in South Asians. METHODS: In this retrospective study, patients with liver cirrhosis who underwent living-donor liver transplantation (LDLT) at Shifa International Hospital in Islamabad, Pakistan, between January 2022 and January 2023 were included...

Ischemia-reperfusion injury (IRI) profoundly impacts organ transplantation, especially in orthotopic liver transplantation (OLT). Disruption of the mitochondrial respiratory chain during ischemia leads to ATP loss and ROS production. Reperfusion exacerbates mitochondrial damage, triggering the release of damage-associated molecular patterns (DAMPs) and inflammatory responses. Mitochondrial dysfunction, a pivotal aspect of IRI, is explored in the context of the regulatory role of ectonucleotidases in purinergic signaling and immune responses...
