Organ donor management

BACKGROUND: Approximately 70% of Sub-Saharan African countries have experienced armed conflicts with significant battle-related fatalities in the past two decades. Niger has witnessed a substantial rise in conflict-affected populations in recent years. In response, international cooperation has aimed to support health transformation in Niger's conflict zones and other conflict-affected areas in Sub-Saharan Africa. This study seeks to review the available evidence on health interventions facilitated by international cooperation in conflict zones, with a focus on Niger...

Lung transplantation in Japan is an increasingly accessible treatment option for end-stage lung disease; however, the lack of donor organs is a persisting challenge. Five- and 10-year survival rates of lung transplant recipients in Japan are comparable, if not superior, to international standards. The outcomes of lung transplantation in Japan are likely affected by multiple factors. Infectious disease complications are a significant burden to transplant recipients and account for approximately 30% of recipient mortality in Japan, presenting a major challenge in peri-transplant management...

Owing to the extremely short supply of donor lungs in Japan, a unique medical consultant (MC) system was initiated in 2002 to increase the organ availability through intensive management of donors. First, heart transplant surgeons were sent to procurement hospitals as MCs to assess donor organ function and provide intensive care to donors. MCs requested that donor attending doctors perform frequent phlegm aspiration with a bronchoscope, leading to a higher lung availability and better outcomes after lung transplantation...

The utilization of anaerobic hydrolysate from agroforestry wastes is limited by dissolved lignin and aromatics, which have received insufficient attention despite their potential as excellent carbon sources for denitrification. This study aims to investigate the influence of hematite on lignin-derived aromatic compounds and denitrifying carbon sources, as well as to identify iron-reducing bacteria that utilize lignin-derived aromatic compounds as electron donors. The findings revealed that hematite facilitated the anaerobic fermentation of plant biomass, resulting in the production of small molecular organic acids...

Multi-organ transplantation involves the transplant of two or more organs from a single donor into a single recipient; in most cases, one of these organs is a kidney. Multi-organ transplantation is uncommon in pediatric transplantation but can be life-saving or significantly life-improving for children with rare diseases, including primary heart, liver, pancreas, or intestinal failure with secondary kidney failure, metabolic disorders, and genetic conditions causing multi-organ dysfunction. This manuscript reviews the current state of pediatric multi-organ transplantation that includes a kidney, with a focus on indications, evaluation, and key differences in management compared to kidney-alone transplantation...

In this transformative era of organ transplantation, integrating Smart Match and artificial intelligence (AI) emerges as a pivotal advancement, revolutionizing organ allocation processes. Smart Match employs AI algorithms, enhancing organ matching precision and optimizing transplantation outcomes. Leveraging machine learning addresses complexities in donor-recipient pairing, immunosuppression management, and post-operative care, promising to minimize waitlist mortality and improve patient wellbeing. The multifaceted potential of Smart Match lies in its ability to not only streamline current practices but also pave the way for future innovations in solid organ transplantation...

The Histocompatibility and Immunogenetics laboratories provide disease association and pharmacogenetic analyses as well as the tests required for transplantation immunology and transfusion medicine. They perform Human Leukocyte Antigen (HLA) genotyping in patients/recipients and potential donor candidates for solid organ and stem cell transplants using various molecular methods, and determine mismatches. In addition, they also perform HLA antibody tests to detect anti-HLA antibodies in patients and flow cross-matches to evaluate donor-recipient compatibility...

A current inconsistency in organ donation is the ability for a family to veto a valid consent for organ donation by a deceased individual; yet the family is unable to veto a valid refusal. Reasons proposed for accepting or rejecting family veto include concerns regarding distress (individual's family vs potential recipients), impact on organ donation rates, and regard for the deceased individual's autonomy. Advance care directives (ACDs) provide an ethical and legal framework for documenting medical treatment decisions which allow an individual to provide directives and to appoint a medical treatment decision-maker to act on their behalf...

Based on the current projection of the general population and the combined increase in end-stage kidney disease with age, the number of elderly donors and recipients is increasing, raising crucial questions about how to minimize the discard rate of organs from elderly donors and improve graft and patient outcomes. In 2002, extended criteria donors were the focus of a meeting in Crystal City (VA, USA), with a goal of maximizing the use of organs from deceased donors. Since then, extended criteria donors have progressively contributed to a large number of transplanted grafts worldwide, posing specific issues for allocation systems, recipient management, and therapeutic approaches...

Health professionals, despite increasing challenges, with notable exceptions, always pursue peace through health because it is who we are-we are here to heal both at the individual and the community level. This applies to the long-standing Israeli-Palestinian conflict. Unfortunately, till now, nongovernmental organizations have had minimal impact on the conflict. This commentary makes 2 recommendations for donor countries after the fighting subsides: Do not insist on Israeli-Palestinian joint ventures at least for the short term and focus as much as possible your funding on interventions that improve community health...

Lung transplantation is considered as the ultimate therapy for children with advanced pulmonary disease. International data show a median conditional 1-year post-transplantation survival of 9.1 years. Recently, antibody-mediated rejection (AMR) has increasingly been recognized as an important cause of allograft dysfunction although pediatric reports are still scarce. Donor-specific anti-human leukocyte antigen (HLA) antibodies (DSA) are known to play a role in AMR development post-transplant but AMR pathogenesis is still poorly understood...

BACKGROUND: Biliary complications are common in pediatric liver transplant. Strictures resistant to interventional radiology procedures can be extremely challenging to manage and may result in the need of surgery or retransplantation. METHODS: This case report illustrates the use of biodegradable stents post left lateral segment live donor liver transplant in a pediatric patient with a recalcitrant chronic stricture of the biliary-enteric anastomosis. The patient developed a high stricture requiring multiple interventions and eventual access of both the segment II and segment III ducts of the graft...

Circumferential skin defects of the fingers are a technical challenge. Although rare, their management should respect tissue organization and functional abilities. We report two cases of circumferential skin defect. Management used individually tailored "wrap-around" flaps taken from the hallux. The sample concerned the proximal cutaneous sheath of the first toe and the neurovascular pedicle of the first inter-metatarsal space. Nail and toe pad were spared. Both cases had complex circumferential skin defect of the finger, involving the neuro-vascular pedicle...

INTRODUCTION: Mitochondrial DNA depletion syndrome (MDS) is a kind of autosomal recessive genetic disorder associated with a reduction in mitochondrial DNA (mtDNA) copy number caused by mutations in nuclear genes during nucleotide synthesis, which affects the energy production of tissues and organs. Changes in hemodynamics during liver transplantation may lead to high energy-demanding organs and tissues being vulnerable. This report described the intraoperative management during liver transplantation in a child with MDS...

Post-transplant lymphoproliferative disorders (PTLD) is a devastating complication of kidney transplantation with an insidious presentation and potential to disseminate aggressively. This review delineates the risk factors, prognostic indexes, screening, current management algorithm and promising treatment strategies for PTLD. Kidneys from both extended criteria donors (ECD) and living donors (LD) are being increasingly used to expand the donor pool. This review also delineates whether PTLD outcomes vary based on these donor sources...

INTRODUCTION: This case describes passenger lymphocyte syndrome (PLS) generating human platelet antigen 1a (HPA-1a) alloantibodies against the recipient's platelets after liver transplant. Given the rarity of PLS, especially in liver transplant with HPA-1a alloantibodies, disease course and management options are poorly described. METHODS: The patient had cirrhosis secondary to nonalcoholic steatohepatitis complicated by hepatocellular carcinoma, encephalopathy, and severe ascites...

BACKGROUND: Malaria elimination requires closely co-ordinated action between neighbouring countries. In Southern Africa several countries have reduced malaria to low levels, but the goal of elimination has eluded them thus far. The Southern Africa Development Community (SADC) Malaria Elimination Eight (E8) initiative was established in 2009 between Angola, Botswana, Eswatini, Mozambique, Namibia, South Africa, Zambia, and Zimbabwe to coordinate malaria interventions aiming to eliminate malaria by 2030...

Objective: To investigate the perioperative management of wounds associated with secondary sternal osteomyelitis and/or mediastinitis after sternotomy, and to evaluate its clinical effects. Methods: This study was a retrospective observational study. From January 2017 to December 2022, 36 patients with wounds associated with secondary sternal osteomyelitis and/or mediastinitis after sternotomy who were conformed to the inclusion criteria were admitted to the Burn Center of PLA of the First Affiliated Hospital of Air Force Medical University, including 23 males and 13 females, aged 25 to 81 years...

INTRODUCTION AND OBJECTIVES: Due to organ shortages, liver transplantation (LT) using donation-after-circulatory-death (DCD) grafts has become more common. There is limited and conflicting evidence on LT outcomes using DCD grafts compared to those using donation-after-brain death (DBD) grafts for patients with hepatocellular carcinoma (HCC). We aimed to summarize the current evidence on the outcomes of DCD-LT and DBD-LT in patients with HCC. MATERIALS AND METHODS: Online databases were searched for studies comparing DCD-LT and DBD-LT outcomes in patients with HCC and a meta-analysis was conducted using fixed- or random-effects models...

Respiratory viral infections (RVIs) are among the leading cause of morbidity and mortality in pediatric hematopoietic stem cell transplant (HCT) and solid organ transplant (SOT) recipients. Transplant recipients remain at high risk for super imposed bacterial and fungal pneumonia, chronic graft dysfunction, and graft failure as a result of RVIs. Recent multicenter retrospective studies and prospective studies utilizing contemporary molecular diagnostic techniques have better delineated the epidemiology and outcomes of RVIs in pediatric transplant recipients and have advanced the development of preventative vaccines and treatment interventions in this population...
