BACKGROUND: Hepatic dysfunction is often associated with advanced heart failure. Its impact on complications following heart transplantation is not well known. We studied the influence of preoperative hepatic dysfunction on the results of heart transplantation with a specific priority access for critical patients. METHODS: Consecutive heart transplantation patients were retrospectively analyzed at listing to detect predictive factors for early complications and survival following heart transplantation...

Traumatic brain injury (TBI) is a disruption in the brain functions following a head trauma. Cell therapy may provide a promising treatment for TBI. Among different cell types, human neural stem cells cultured in self-assembling peptide scaffolds have been suggested as a potential novel method for cell replacement treatment after TBI. In the present study, we accessed the effects of human neural stem/progenitor cells (hNS/PCs) derived from epileptic human brain and human adipose-derived stromal/stem cells (hADSCs) seeded in PuraMatrix hydrogel (PM) on brain function after TBI in an animal model of brain injury...

BACKGROUND AND OBJECTIVES: Despite the important role that health care providers at dialysis facilities have in reducing racial disparities in access to kidney transplantation in the United States, little is known about provider awareness of these disparities. We aimed to evaluate health care providers' awareness of racial disparities in kidney transplant waitlisting and identify factors associated with awareness. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: We conducted a cross-sectional analysis of a survey of providers from low-waitlisting dialysis facilities ( n =655) across all 18 ESRD networks administered in 2016 in the United States merged with 2014 US Renal Data System and 2014 US Census data...

Hematopoietic Stem Cell Transplantation (HSCT) is the only therapeutic option in a number of heritable hematologic disorders as well as hematologic cancers. Many parents and families fail to find an HLA-identical donor for their affected family member. In such cases, conceiving for a savior baby remains the only option especially in countries without access to national registries. By means of Next Generation Sequencing (NGS) techniques, in a single experiment on single cell products of IVF, a healthy HLA-identical embryo can be implanted in the uterus of a concerned mother...

Pediatric stem cell transplant processes require information sharing among the patient, family, and clinicians regarding the child's condition, prognosis, and transplant procedures. To learn about perceived access to transplant information and involvement in decision making among child family members (9-22 years old), we completed a secondary analysis of 119 interviews conducted with pediatric patients, sibling donors, nondonor siblings/cousins, and guardians from 27 families prior to transplant. Perceptions of information access and involvement in transplant-related decisions were extracted and summarized...

The prospects for cell replacement in spinal cord diseases are impeded by inefficient stem cell delivery. The deep location of the spinal cord and complex surgical access, as well as densely packed vital structures, question the feasibility of the widespread use of multiple spinal cord punctures to inject stem cells. Disorders characterized by disseminated pathology are particularly appealing for the distribution of cells globally throughout the spinal cord in a minimally invasive fashion. The intrathecal space, with access to a relatively large surface area along the spinal cord, is an attractive route for global stem cell delivery, and, indeed, is highly promising, but the success of this approach relies on the ability of cells (1) to survive in the cerebrospinal fluid (CSF), (2) to adhere to the spinal cord surface, and (3) to migrate, ultimately, into the parenchyma...

Background: Intravenous drug use is associated with progressive kidney disease of several aetiologies. It is associated with behavioural and lifestyle characteristics that make the provision of renal replacement therapies (RRTs) challenging. We observed that patients who use intravenous drugs [people who inject drugs (PWID)] present late to renal services and struggle to engage with treatment. We describe the experience of a UK centre providing renal services to a mixed city and rural population...

OBJECTIVE: Alternative sites to the liver for islet transplantation have been studied for a long time. Intramuscular islet transplantation appears to be an alternative site to the liver because of the ease of access. First islet autotransplantations were reported in patients after total pancreatectomies. The transplanted islets showed a proper revascularization and their function was observed for up to 2 years after the implant. However, only a few cases of autotransplantation and no allotransplantation have been performed...

BACKGROUND New oral anticoagulants like direct thrombin inhibitors are an attractive alternative to vitamin K antagonists as anticoagulation therapy and can be used in heparin-induced thrombocytopenia. They are convenient in low-risk surgery, as there is no need for bridging with heparins. Patients who need urgent major surgery are at similar risk as on warfarin therapy, which, however, is much higher than in elective procedures. Due to their elimination profiles, these drugs are generally contraindicated in patients with severe renal insufficiency...

Pancreatic islet transplantation is a promising treatment option for individuals with type 1 diabetes; however, maintaining islet function after transplantation remains a large challenge. Multiple factors, including hypoxia associated events, trigger pretransplant and posttransplant loss of islet function. In fact, islets are easily damaged in hypoxic conditions before transplantation including the preparation steps of pancreas procurement, islet isolation, and culture. Furthermore, after transplantation, islets are also exposed to the hypoxic environment of the transplant site until they are vascularized and engrafted...

BACKGROUND: ABO-incompatible (ABOi) living donor liver transplantation (LDLT) have been performed to compensate for donor shortage. To date, few studies have reported detailed B cell desensitization protocols and long-term outcomes of ABOi pediatric LDLT. METHODS: Twenty-nine pediatric ABOi LDLT recipients were retrospectively analyzed. We compared the clinical outcomes between ABOi (n = 29) and non-ABOi (n = 131) pediatric LDLT recipients. Furthermore, we evaluated the safety and efficacy of our rituximab-based regimen for ABOi pediatric LDLT (2 ≤ age < 18, n = 10)...

BACKGROUND: Sex-based disparities in liver transplantation (LT) are incompletely understood. We assessed the role of height, MELD, MELD-Na and exception points in the disparate access to LT. METHODS: Adults waitlisted for LT at Organ Procurement and Transplantation Network (OPTN) between 2002 and 2013 were included. Covariates associated with likelihood of LT were analyzed by Cox proportional model. In a separate cohort of waitlisted adults with glomerular filtration rate (GFR) measurement by iothalamate clearance (n=611), we determined the number of creatinine-derived MELD points in men vs women, across all ranges of GFR...

As the use of fecal microbiota transplantation (FMT) has gained momentum, an increasing need for continuous access to healthy feces donors has developed. Blood donors constitute a healthy subset of the general population and may serve as an appropriate group for recruitment. In this study, we investigated the suitability of blood donors as feces donors. In a prospective cohort study, we recruited blood donors onsite at a public Danish blood bank. Following their consent, the blood donors underwent a stepwise screening process: First, blood donors completed an electronic pre-screening questionnaire to rule out predisposing risk factors...

Central venous thromboses are common and pose challenges in the care of chronically ill pediatric patients. Among patients with intestinal failure (most commonly because of short bowel syndrome) who depend on parenteral nutrition, progressive loss of central venous access sites is a potentially fatal complication. We present the case of a 5-year-old girl with parenteral nutrition-dependent short bowel syndrome and no remaining standard central venous access sites despite medical anticoagulation, in whom angioplasty and stent implantations were used to reconstruct chronically occluded central veins...

Contemporary modalities for cardiopulmonary support during lung transplantation include traditional cardiopulmonary bypass (CPB) and venoarterial extracorporeal membrane oxygenation (VA-ECMO). While highly effective, both are associated with morbidities such as arteriopathy and bleeding diathesis. In this report, we describe a novel approach for cardiopulmonary support during double lung transplantation in a patient with end-stage lung disease, pulmonary hypertension and moderate right ventricle (RV) dysfunction, using a percutaneous dual lumen cannula placed via the jugular vein which allowed us to achieve both RV bypass and membrane oxygenation...

INTRODUCTION: Simultaneous kidney and pancreas transplant is the preferred treatment option for end-stage renal disease due to type 1 diabetic nephropathy. Vascular complications are detrimental to graft survival and can lead to graft loss in the early postoperative phase of transplantation. Generally, duplex Doppler ultrasound is used for vascular patency monitoring and pancreatectomy followed by re-transplantation is required in the majority of cases. Recently, pancreatic graft salvage with non-operative management, including medical anticoagulation and endovascular thrombectomy, in the early postoperative period has been described with success...

By cause of the shortfall between the number of patients listed for liver transplantation (LT) and available grafts, strategies to expand the donor pool have been developed. Donation after Circulatory Death (DCD) and Living donor (LD) grafts are not universally used due to the concerns of graft failure, biliary complications and donor risks. In order to overcome the barriers for the implementation of using all three types of grafts, we compared outcomes after LT of DCD, LD and donation after brain death (DBD) grafts...

Del17p is a genomic imbalance occurring in ∼7-10% of myeloma at diagnosis (NDMM) and comprises a poor prognostic factor. The goal of this study is to analyze real world data and outcomes among NDMM patients carrying 17p deletion. We report an observational, retrospective, multicenter study. Sixty consecutive patients diagnosed with multiple myeloma in the 8 participating centers diagnosed between 1/2008-1/2016 proven to carry 17p deletion by means of FISH were identified. Most received a bortezomib-based induction, over half underwent autologous hematopoietic cell transplantation (HCT); 30% of the patients gained early access to new novel agents via clinical trials, access programs or private insurance...
