Outcomes of Patients with Hepatocellular Carcinoma Undergoing Liver Transplantation Utilizing Extended Criteria Donor Grafts.

Background: The deceased donor shortage in the United States has led to increased utilization extended criteria donor (ECD) liver grafts. Centers often utilize ECD grafts in patients with low Model for End-Stage Liver Disease (MELD) scores, like patients with hepatocellular carcinoma (HCC). However, few studies have directly examined the outcomes of using ECD grafts in patients with HCC.

The Impact of Kidney/Pancreas Transplantation on Peripheral Arterial Disease.

Introduction: It is unclear whether kidney/pancreas (KP) transplantation will prevent the progression of peripheral arterial disease (PAD) in patients with insulin dependent diabetes (IDDM) and end-stage renal disease. We sought to determine the pre- and posttransplant prevalence of symptomatic PAD and changes in carotid artery intima-media thickness (IMT) in KP recipients.

Methods: In this single center study, outcomes were compared between KP recipients with and without a history of PAD.

Single-center Outcomes After Liver Transplantation With SARS-CoV-2-Positive Donors: An Argument for Increased Utilization.

Background: The COVID-19 pandemic has led to an increase in SARS-CoV-2-test positive potential organ donors. The benefits of life-saving liver transplantation (LT) must be balanced against the potential risk of donor-derived viral transmission. Although emerging evidence suggests that the use of COVID-19-positive donor organs may be safe, granular series thoroughly evaluating safety are still needed.

Bloodstream infections after solid organ transplantation: clinical epidemiology and antimicrobial resistance (2016-21).

Background: Solid organ transplant (SOT) recipients are at risk of bloodstream infections (BSIs) with MDR organisms (MDROs).

Objectives: To describe the epidemiology of BSI in the year after several types of SOT, as well as the prevalence of MDRO infections in this population.

Methods: We conducted a single-centre, retrospective study of kidney, liver, heart, and multi-organ transplantation patients.

Revitalizing pancreas transplantation: creation of a hands-on training course for pancreas allograft procurement, backbench preparation, and transplantation.

Despite a steady increase in the number of organs available for transplant in the United States, over the last two decades there has been a precipitous decrease in the annual number of pancreas transplants performed. One overlooked consequence of this decline in pancreas transplant volume has been a decrease in experience in proper pancreas procurement and transplantation techniques for transplant surgeons as well as fewer trained abdominal transplant fellows entering the workforce certified for pancreas procurement and transplantation, with those achieving certification having less-developed judgment, skills, and experience. To augment current fellowship training and provide a concentrated experience in pancreas procurement and transplantation, the ASTS developed a hands-on surgical skills workshop focused on proper techniques for pancreas allograft procurement and backbench preparation.

Progress in Combined Liver-lung Transplantation at a Single Center.

Unlabelled: Combined liver-lung transplantation is an uncommon, although vital, procedure for patients with simultaneous end-stage lung and liver disease. The utility of lung-liver transplant has been questioned because of initial poor survival outcomes, particularly when compared with liver-alone transplant recipients.

Methods: A single-center, retrospective review of the medical records of 19 adult lung-liver transplant recipients was conducted, comparing early recipients (2009-2014) with a recent cohort (2015-2021).

Deceased donor vein extension grafts for right living donor kidney transplantation.

Introduction: In an effort to maximize living donor kidney utilization, we describe the use of deceased donor vein extension grafts for right-sided living donor kidneys and report our single-center experience using this technique.

Methods: A retrospective review of kidney transplant recipients (KTR) who received a right living donor kidney with deceased donor vein extension graft. Recipient demographics, postoperative graft function, and surgical complications were reviewed.

Modern Outcomes After Liver Retransplantation: A Single-center Experience.

Background: The need for liver retransplantation (reLT) has increased proportionally with greater numbers of liver transplants (LTs) performed, use of marginal donors, degree of recipient preoperative liver dysfunction, and longer survival after LT. However, outcomes following reLT have been historically regarded as poor.

Methods: To evaluate reLT in modern recipients, we retrospectively examined our single-center experience.

Outcomes of a High-Volume Organ Procurement Organization in the Era of Increasing Donation After Circulatory Death.

Donation after circulatory death (DCD) is rapidly increasing in the United States. Detailed data outlining the process from referral to organ transplantation is lacking. We sought to quantify differences at each stage along the referral to donation pathway by donor type.

Combined liver transplantation and sleeve gastrectomy: Report of a brief-interval staged approach.

Pretransplantation bariatric surgery in patients with high Model for End-Stage Liver Disease (MELD) score is fraught with risks. Bariatric surgery after liver transplantation (LT) may be complicated by surgical adhesions but could have advantages if performed at the time of transplantation. We investigated a method of brief-interval staging combining LT and sleeve gastrectomy (SG).

Risk Factors Associated With an Impaired Antibody Response in Kidney Transplant Recipients Following 2 Doses of the SARS-CoV-2 mRNA Vaccine.

Background: Data about vaccine efficacy in solid organ transplant patients are limited. We previously reported our initial observation of a 6.2% immunogenicity rate in kidney transplant recipients (KTRs) after administration of 1 dose of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) mRNA vaccine.

Successful Treatment of Invasive Mucormycosis in Orthotopic Liver Transplant Population.

Mucormycosis is caused by ubiquitous fungi and encompasses a variety of different opportunistic syndromes in humans that disproportionately affect immunocompromised patients. Mortality has been documented to range between 50 and 100%; however, location of infection greatly dictates likelihood of survival. Treatment of mucormycosis involves aggressive surgical intervention and combination therapy of antifungal agents.

Timing and types of fluids and foods first introduced in a representative sample of toddlers attending day care programs across Lebanon: Are parents following international recommendations?

Background: Current WHO's recommendation for optimal infant feeding advises exclusive breastfeeding for 6 months. After this initial period, infants should receive nutritionally adequate and safe complementary food starting from the age of 6 months with continued breastfeeding up to 2 years of age or beyond.

Purpose: This study examined the timing and types of fluids and foods first introduced in a representative sample of toddlers (n = 1051) from 79 daycares across Lebanon.

In silico deceased donor intervention research: A potential accelerant for progress.

Progress in deceased donor intervention research has been limited. Development of an in silico model of deceased donor physiology may elucidate potential therapeutic targets and provide an efficient mechanism for testing proposed deceased donor interventions. In this study, we report a preliminary in silico model of deceased kidney donor injury built, calibrated, and validated based on data from published animal and human studies.

Impact of Protease Inhibitor-Based Antiretroviral Therapy on Tacrolimus Intrapatient Variability in HIV-Positive Kidney Transplant Recipients.

Background: Human immunodeficiency virus (HIV)-positive kidney transplant (KT) recipients have been shown to experience higher rejection rates due in part to drug-drug interactions between antiretroviral therapy (ART) and immunosuppression regimens. High tacrolimus (FK) intrapatient variability (IPV) is associated with inferior outcomes in KT. The purpose of this study was to determine the impact of protease inhibitor (PI)-based ART on FK IPV and graft outcomes.
