Veno-venous extracorporeal membrane oxygenation (ECMO) has become a viable and increasingly utilized option for the treatment of refractory hypoxemia in severe acute respiratory distress syndrome (ARDS). However, options are limited for ARDS patients who fail to wean from ECMO. The high rates of infection, presence of extrapulmonary end organ damage, ICU-acquired weakness, and high short-term mortality associated with ARDS are all significant hurdles that make lung transplantation a difficult prospect to consider...

Acute kidney injury (AKI) is a common complication in liver transplant recipients. Affecting ~25% of patients preoperatively, and up to 60% postoperatively significantly worsens the prognosis. Etiology differs depending on the time of its onset, from mostly prerenal before the transplantation, ischemic in the early postoperative period to toxic AKI later on. Liver transplantation is a lenghty and complex procedure with a significant risk of hemodynamic instability, metabolic acidosis and electrolyte disturbances...

Four hundred forty-one adult allogeneic blood and marrow transplantation (BMT) survivors participated in a cross-sectional survey to assess long-term follow-up (LTFU) model of care preference. Survey instruments included the Sydney Post BMT Survey, Functional Assessment of Cancer Therapy-BMT, Depression Anxiety Stress Scales 21, the Chronic GVHD Activity Assessment-Patient Self Report (Form B), the Lee Chronic GVHD Symptom Scale and the Post-Traumatic Growth Inventory. We found most BMT survivors (74%) would prefer LTFU with their transplantation physicians alone or in combination with transplantation center-linked services (satellite clinics or telemedicine) Over one-quarter indicated a preference for receiving comprehensive post-transplantation care in a "satellite" clinic staffed by their BMT team situated closer to their place of residence, with higher income, higher educational level, and sexual morbidity being significant social factors influencing this preference...

As human umbilical cord mesenchymal stem cells (hUC-MSCs) transplanation may be promising in heart failure treatment, it is important to know whether hypoxic preconditioning (HP) promote hUC-MSCs proliferation and differentiation and protect them against chemical hypoxic damages. This study aimed to investigate the effects of HP on proliferation and differentiation of human umbilical cord mesenchymal stem cells (hUC-MSCs). The study also aimed to confirm our hypothesis that HP could promote hUC-MSCs proliferation and differentiation to cardiomyocyte-like cells as well as effectively protecting hUC-MSCs and cardiomyocyte-like cells against chemical hypoxic damages...

We report a rare case of primary renal allograft dysfunction due to myeloma cast nephropathy in a patient with no overt clinical features of multiple myeloma preceding his transplantation. A 45-year-old man on hemodialysis for six months for end-stage kidney disease due to presumed chronic glomerulonephritis developed immediate graft dysfunction post-transplantation. The graft biopsy was diagnostic of myeloma cast nephropathy. Other criteria for lambda light chain multiple myeloma were fulfilled with immunofixation electrophoresis and bone marrow biopsy...

We report the first case of a 32-year-old woman with Muckle-Wells syndrome and biopsy-proven systemic AA amyloidosis and end-stage renal disease. She was treated with canakinumab 150 mg subcutaneously every 8 weeks and underwent renal transplantation. Fourteen months after renal transplanation, the patient had no flares of Muckle-Wells syndrome and no evidence of amyloidosis in the renal transplant under an excellent graft function and therapy with canakinumab.

Left ventricular assistance with surgically implanted pump devices like the HeartMate may be crucial in selected patient with end-stage heart failure. However, mainly due to its high aortic output, the pump itself may induce severe aortic regurgitation that could result in paradoxycal worsening of the anterograde perfusion after the initiation of the support. Surgical or percutaneous occlusion of the aortic valve has proved useful in these kinds of patients. Here we present a successful case of bail-out CoreValve implantation after HeartMate II positioning complicated by acute severe aortic regurgitation in a patient with a failing homograft and end-stage ventricular dysfunction, ineligible for heart transplanation...

Hematopoiesis is regulated by the bone marrow (BM) niche microenvironment. We recently found that posttransplant administration of AMD3100 (a specific and reversible CXCR4 antagonist) enhanced donor cell engraftment and promoted recovery of all donor cell lineages in a congeneic mouse transplant model. We hypothesized that AMD3100 enhances donor cell reconstitution in part by modulating the levels and constitution of soluble factors in the niche microenvironment. In the current study, the effects of the BM extracellular fluid (supernatant) from AMD3100-treated transplant recipient mice on colony-forming units (CFUs) were examined...

BACKGROUND: Postoperative cognitive dysfunction (POCD) is an adverse condition characterized by declined cognitive functions following surgeries and anesthesia. POCD has been associated with increased hospital stay and mortality. There are histological similarities to Alzheimer's disease. Most early studies were conducted in patients receiving cardiac surgery. Since there is no information about POCD in liver transplant recipients, we measured the incidence of POCD in patients after liver transplantation and examined the correlation between neurological dysfunction and biological markers of dementia-based diseases...

BACKGROUND: Although rituximab added to CHOP (cyclophosphamide/doxorubicin/vincristine/prednisone) is the standard chemotherapy for untreated DLBCL, its therapeutic effect is limited in younger patients with high-intermediate risk or high-risk disease according to the age-adjusted international prognostic index. In fact, the efficacy and safety of HDT plus rituximab followed by ASCT for such patients remain unclear. PATIENTS AND METHODS: We retrospectively investigated the safety and effectiveness of HDT/ASCT in patients with untreated DLBCL...

The risk of renal transplanation patients developing de novo malignancy is increased 100-fold compared with the healthy nontransplantation population. Renal cell carcinoma (RCC) arising from native kidneys is diagnosed among up to 4.6% of the renal transplant recipients as a consequence of immunosuppression. These tumors tend to behave more aggressively.(1) Although tumors occurring in allografted kidneys can be treated by partial (to save functional graft) or total nephrectomy, there is a paucity of data the outcomes...

In this paper we present a hybrid OD-3D modeling method to investigate the hepatic flow in a virtual right lobe hepatectomy (RLH), the surgical procedure for adult-to-adult living donor liver transplanation (LDLT). The 3D method is employed to simulate complex 3D flow in the portal vein, and the OD model is used to study the systemic hepatic circulation. In particular, we quantify the flow velocity and wall shear stress (WSS) in the left portal vein which increase dramatically post-RLH, and also simulate the essential hepatic distribution features in a healthy adult pre- and post-procedure...

OBJECTIVE AND BACKGROUND: There is little information regarding the serologic status of umbilical cord blood (UCB) donors. Cytomegalovirus (CMV) is the most frequent agent transmitted by blood products and studies have reported that CMV can inhibit myelopoiesis, however, its effects on the cellular content of UCB have not been documented. STUDY DESIGN AND METHODS: We investigated, retrospectively, the prevalence of serological evidence of infection in 857 women donating their UCB at a public university hospital and studied the influence of acute CMV exposure on UCB content of CD34+ cells...

OBJECTIVE: To determine whether portoenterostomy (PE) revision in patients afflicted with biliary atresia (BA) is a viable treatment option and, if so, identify which patients may benefit. BACKGROUND: BA, the most common cause of neonatal liver disease, results in biliary tract obstruction and hepatic fibrosis. Kasai PE is the initial surgical intervention performed and, if successful, restores drainage and preserves the native liver. Portoenterostomy failure warrants liver transplantation, but because of complications related to transplantation, treatment strategies to salvage the native liver may be beneficial...

Treatment of recurrent hepatitis C after liver transplantation is indicated in selected cases. During the combined treatment with pegylated interferon and ribavirin, some patients develop immune-mediated liver dysfunction similar to the previously described "de novo" autoimmune hepatitis. Herein we have presented three liver transplant patients who during or after combined antiviral treatment were diagnosed as autoimmune hepatitis related to interferon based on their clinical, biochemical, and liver histology features...
