European guidelines for diagnosis and treatment of adenovirus infection in leukemia and stem cell transplantation: summary of ECIL‐4 (2011)
Abstract Human adenovirus (HAdV) infections are increasingly recognized as important pathogens in immunocompromised hosts, especially in patients with severely suppressed T‐cell function. The 4th European Conference of Infections in Leukemia (ECIL‐4) has developed evidence‐based guidelines for diagnosis and management of HAdV infections. The risk for HAdV‐associated disease is increased in children, and risk factors for HAdV disease are T‐cell depletion, unrelated and cord blood hematopoietic stem cell transplantation, graft‐versus‐host disease grades III–IV, and lymphopenia. The recommended technique for m...

Selective Cerebro‐Myocardial Perfusion Under Mild Hypothermia During Primary Repair for Aortic Coarctation With Ventricular Septal Defect
Abstract Controversy still exists on the use of deep hypothermic circulatory arrest (DHCA) and selective antegrade cerebral perfusion (SACP) on postoperative recovery. Selective cerebro‐myocardial perfusion (SCMP) has been described in neonatal and infant arch surgery. We therefore report outcomes of patients undergoing SCMP under mild hypothermia compared with DHCA and SACP. One hundred ten consecutive patients undergoing anatomic reconstruction of coarctation of the aorta (CoA) with ventricular septal defect (VSD) closure between January 1999 and July 2011 were retrospectively reviewed. Patients repaired under continuo...

Medical Outcomes in African American Live Kidney Donors: A Matched Cohort Study
It is uncertain if live kidney donation increases future risk of hypertension and kidney disease in African Americans. We conducted a cohort study across two transplant centers enrolling African Americans who donated between 1993 and 2006. A comparison group of African American nondonors were selected from healthy participants in the Coronary Artery Risk Development in Young Adults (CARDIA) prospective cohort study. A total of 103 donors and 235 matched nondonors were assessed at mean ( ± SD) of 6.8 ± 2.3 and 6.4 ± 2.2 years after donation or cohort entry, respectively. The primary outcome was risk of hypertension in do...

Endovascular caudal retraction of the cranial end of a misplaced Viatorr TIPS prior to liver transplantation.
We describe the first known manipulation of a covered stent graft prior to transplantation. The stent graft, which extended well into the IVC, was snared from a femoral approach and deflected caudally in order to document feasibility and nonadherence to the vein wall prior to definitive surgical planning of liver transplantation. Provisions were made for endovascular retraction during actual transplant surgery 9 weeks later, but this became unnecessary when manual retraction of the exposed liver enabled suprahepatic IVC clamping. Due to the nonadherent nature of the outer graft material, compared with a bare metal stent, e...

Cholestatic hepatitis C following liver transplantation: An outcome‐based histological definition, clinical predictors and prognosis
Conclusions: We propose diagnostic criteria for cholestatic HCV, which include specific criteria (the presence of ò 3 of 4 histopathologic lesions on biopsy) and other supportive and exclusionary criteria. Older donor age and rejection increase the risk of cholestatic HCV, and elevation in TB may help identify these patients. © 2012 American Association for the Study of Liver Diseases

The Protective Effect of St. Thomas Cardioplegia Enriched With Zacopride on the Isolated Rat Heart
Abstract The activation of the heart inward rectifier potassium channel (IK1) can reduce the injury of myocardial cells by shortening the action potential duration and reducing intracellular calcium overload. Zacopride is a selective IK1 agonist and suppresses triggered arrhythmias in rat hearts. This investigation studied the effects of St. Thomas (ST) cardioplegia enriched with Zacopride on the isolated rat heart model. Sprague‐Dawley rat hearts were harvested and perfused for 20 minutes with 37°C Krebs‐Henseleit (KH) buffer followed by 15 minute perfusion with 4°C calcium‐free KH buffer in the Control group (Con...

Approach to kidney transplant in sensitized potential transplant recipients.
Abstract More than one-third of patients on waiting lists for kidney transplant are sensitized. Most have previously formed donor-specific and non-donor-specific serum antibodies and/or positive crossmatch by complement-dependent cytotoxity and/or flow cytometry. Two categories of alloantibodies include antibodies against major histocompatibility complex human leukocyte antigen class 1 and class 2 and antibodies against minor histocompatibility complex. A current positive crossmatch is an absolute contraindication for transplant. Positive historical panel reactive antibody and/or donor-specific antibodies (human le...

Risk factors for steroid-resistant T-cell-mediated acute cellular rejection and their effect on kidney graft and patient outcome.
CONCLUSIONS: Prebiopsy low cyclosporine trough levels and associated chronic changes among patients who were maintained on calcineurin inhibitor-based regimens represented the most-important risk factors for the early steroid-resistant group. Rescue therapies improve short-term graft outcome; however, they did not affect either patient or long-term graft survival after 5 years' follow-up. PMID: 23031083 [PubMed - in process]

Resistive index of the remaining kidney in allograft kidney donors.
CONCLUSIONS: Although a statistically significant increase in resistive index values of the remaining kidney was seen 90 days after the nephrectomy, these values have remained within the normal limits of renal resistive index. So, our findings indicate that resistive index measurement is useful in assessing the diseased condition of the remaining kidney after removing the contralateral kidney.

Impact of Single-Ventricle Physiology on Death After Heart Transplantation in Adults With Congenital Heart Disease [ORIGINAL ARTICLES: PEDIATRIC CARDIAC]
Conclusions Overall case-mix of ACHD recipients (1V vs 2V) has not changed over time. Initial 1V anatomy increases post-HTx death among ACHD recipients, whereas 2V patients have mortality rates similar to non-CHD recipients. National and international transplant registries should include specific CHD diagnoses because this factor plays such a large role in determining early outcomes.

Expression of Pancreatic Endocrine Markers by Mesenchymal Stem Cells From Human Adipose Tissue
Abstract: Mesenchymal stem cells (MSCs) from human adipose tissue have a great potential for use in cell therapy due to their ease of isolation, expansion, and differentiation, besides the relative acceptance from the ethical point of view. Our intention was to isolate and promote in vitro expansion and differentiation of MSCs from human adipose tissue into cells with a pancreatic endocrine phenotype. Human adipose tissue obtained from patients undergoing abdominal dermolipectomy was digested with type I collagenase. MSCs isolated by plastic adherence and characterized by cytochemistry and FACS were expanded in vitro. MSC...

Hepatocellular Carcinoma Recurrence Among Liver Transplant Recipients Within the Milan Criteria
Conclusions: Despite strict candidate selection criteria, HCC recurrence may occur after OLT, bearing a significant impact on posttransplant outcomes to optimize results requires refinements in candidate selection, as well as well-defined cost-effective post-OLT surveillance protocols.

Can Pre–Liver Transplantation Renal Insufficiency Using a Creatinine Clearance Calculator Predict Long-Term Survival?
The objective of this study was to study renal insufficiency observed pretransplantation and its long-term impact after liver transplantation. Methods: We analyzed retrospectively an electronic database collected prospectively including transplant records from June 1994 to October 2010 using piggyback venous reconstruction. The exclusion criteria were chronic kidney disease, acute hepatic failure, children up to 12 years of age, and retransplantations. Renal insufficiency was defined by the creatinine clearance (CCr) calculated using the Cockcroft-Gault method. Patients were distributed into 3 groups: CCr >90, between 90...

Early Allograft Dysfunction and Liver Transplant Outcomes: A Single Center Retrospective Study
Conclusion: Patients with EAD show a significantly higher risk for allograft loss, but with a comparable survival after transplantation. Despite their worse outcomes, it seems that not all of these recipients behave equally.
