The management of long bone defects continues to be associated with significant challenges for optimum and timely bone repair. When bone grafting is needed, essential parameters to be addressed include adequate volume, optimum density, and structural capacity as well as potent biological properties. Although the autologous iliac crest bone graft remains the gold standard, its reduced availability and donor site morbidity have made the clinicians to seek for other alternative options. Reamer irrigator aspirator graft with materials used as graft expanders along with inductive molecules and cellular augmentation constitute the current trend for optimum bone regeneration...

OBJECTIVE In various disease processes, including unclippable aneurysms, a bypass to the upper posterior circulation (UPC) including the superior cerebellar artery (SCA) and posterior cerebral artery (PCA) may be needed. Various revascularization options exist, but the role of intracranial (IC) donors has not been scrutinized. The objective of this study was to evaluate the anatomical feasibility of utilizing the anterior temporal artery (ATA) for revascularization of the UPC. METHODS ATA-SCA and ATA-PCA bypasses were performed on 14 cadaver specimens...

Hepatitis C virus (HCV) is a significant problem among hemodialysis population, especially in India where renal transplant often gets delayed in the presence of live-related donors. An acceleration of liver cirrhosis and poor renal allograft outcomes are often witnessed in allograft recipients with high viral load. Use of interferon in the postrenal transplant setting for the treatment of hepatitis C viral infection was limited to a few grave situations, fearing the precipitation of allograft rejection and poor efficacy for sustained virological remission...

Human immunodeficiency virus (HIV) infection has posed as a major global health epidemic for almost three decades. With the advent of highly active antiretroviral therapy in 1996 and the application of prophylaxis and management of opportunistic infections, acquired immunodeficiency syndrome mortality has decreased markedly. The most aggressive HIV-related renal disease is end-stage renal disease due to HIV-associated nephropathy. Presence of HIV infection used to be viewed as a contraindication to renal transplantation for multiple reasons; concerns for exacerbation of an already immunocompromised state by administration of additional immunosuppressants; the use of a limited supply of donor organs with unknown long-term outcomes...

BACKGROUND/AIMS: Autonomic dysfunction (AD) after allogeneic stem cell transplant (SCT) is a rare occurrence and likely immune-mediated in etiology. There is limited literature on this topic and hence, we wish to briefly describe management of two cases at our institution and their outcomes. METHODS: We retrospectively identified two patients with immune-mediated AD after SCT from our database. Immune-mediated AD was defined as AD secondary to an immune-mediated etiology without an alternative cause and responding to immunosuppression...

The liver participates in a multitude of metabolic functions that are critical for sustaining human life. Despite constant encounters with antigenic-rich intestinal blood, oxidative stress and metabolic intermediates, there is no appreciable immune response. Interestingly, patients undergoing orthotopic liver transplantation benefit from a high rate of graft acceptance in comparison to other solid organ transplant recipients. In fact, co-transplantation of a donor liver in tandem with a rejection-prone graft increases the likelihood of graft acceptance...

INTRODUCTION: Hepatic resection is performed for various benign and malignant liver tumors. Over the last several decades, there have been improvements in the surgical technique and postoperative care of patients undergoing liver surgery. Despite this, liver failure following an extended hepatic resection remains a critical potential postoperative complication. Patients with underlying parenchymal liver diseases are at particular risk of liver failure due to impaired liver regeneration with an associated mortality risk as high as 60 to 90%...

BACKGROUND: Brain-dead pediatric donors have always been the focus of attention because of the higher quality, utility, and possibility of their organ donation. However, donors under the age of 5 years always necessitate making more challenging management efforts, which are not clearly implied in most parts of the guidelines. METHODS: The data obtained from 79 brain-dead pediatric donors of the Organ Procurement Unit of Masih Daneshvari Hospital, Tehran, Iran, were assessed...

BACKGROUND: In 2014, we reported a model for Donor-Recipient matching (D-R) in liver transplantation (LT) based on artificial-neural-networks (ANN) from a Spanish multicentre study (MADR-E: Model for Allocation of Donor and Recipient in España). The aim is to test the ANN-based methodology in a different European-healthcare system in order to validate it. METHODS: An ANN model was designed using a cohort of patients from King's College Hospital (KCH) (N=822). The ANN was trained and tested using KCH pairs for both 3- and 12-months survival models...

Coagulation factor VIII (FVIII) is an important glycoprotein involved in the extrinsic coagulation cascade. Mutations in FVIII gene results in hemophilia A, a recessive coagulation disorder that is clinically managed by administration of purified FVIII from blood donors or recombinant FVIII. Because of its fundamental therapeutic application, biotechnological production of FVIII requires rigid quality control and monitoring in patients and clinical trials. Here, we describe a protocol for a mass spectrometry based approach termed selective reaction monitoring (SRM) as an important alternative tool for accurate and sensitive quantitation of purified or recombinant FVIII...

Shoot fly (Atherigona soccata L. Moench) is a serious pest in sorghum production. Management of shoot fly using insecticides is expensive and environmentally un-safe. Developing host-plant resistance is the best method to manage shoot fly infestation. Number of component traits contribute for imparting shoot fly resistance in sorghum and molecular markers have been reported which were closely linked to QTLs controlling these component traits. In this study, three QTLs associated with shoot fly resistance were introgressed into elite cultivars Parbhani Moti (= SPV1411) and ICSB29004 using marker assisted backcrossing (MABC)...

Platelet transfusion refractoriness (PTR) is a major adverse event in the management of acute myeloid leukemia (AML). In a series of 897 adult patients with AML receiving intensive chemotherapy, we identified 41 patients (4.8%) with PTR. PTR was more frequently observed in parous women, patients with extra-medullary disease, a low white blood cell count, an infection, or hemophagocytic syndrome. Among the 31 patients with anti-human leucocyte antigen (HLA) antibodies, an HLA-matched donor was identified for 18 patients (58...

BACKGROUND: Primary immunodeficiency disorders (PIDs) are a heterogeneous group of diseases of the immune system leading to life-threatening infections, and, unless urgently treated with immune reconstitution, patients do not usually survive. With the continuing progress in molecular diagnosis, many mutations have been described in more than 300 genes. Genetic counseling has recently been considered an essential part of the management of PIDs. This study presents the experience of genetic counseling services in the largest PID center in Egypt, and reports on our management plan and the impact of prenatal diagnosis (PND) on families...

In the last two decades, lung transplantation emerged as the standard of care for patients with advanced and terminal lung disease. Despite the increment in lung transplantation rates, in 2016 the overall mortality while on waiting list in Italy reached the 10%, whereas only the 39% of the wait-list patients were successfully transplanted. A number of approaches, including protective ventilatory strategy, accurate management of fluid balance, administration of a hormonal resuscitation therapy have been reported to improve lung donor performance before organ retrieval...

A Bentall, Solomon Shlomo J Cohney
In this week's journal, Axelrod and colleagues examine costs incurred by various US centers undertaking Incompatible Live-Donor Kidney Transplantation (ILDKT) - living donor renal transplantation in the presence of preformed antibody (ies) directed against donor HLA (DSAb) [1]. As expected, cost increased as the immunological barrier intensified (as defined by solid phase and cell based assays). While certain aspects of cost recovery are specific to US health care, effectively managing humoral allo-immunity is important to all transplant clinicians, with little progress despite nearly 2 decades of ILDKT [2, 3]...

The food donation process in Belgium is mapped and analyzed to identify bottlenecks in compliance with the legal framework and implementation of food safety management, based on literature search and interviews with stakeholders (donors, acceptors, regulators and facilitators) in Belgium and at EU level. The study revealed that the food donation/acceptation chain is far less structured and organized than the conventional food supply chain. The fragmented landscape of many small food banks and charity organizations (acceptors), often directed by and working with volunteers without training in food safety and lack of knowledge of legal food hygiene requirements is a bottleneck to generate trust among food donors and restricts the provision of perishable products in food donations...
