With a conditional median survival that now exceeds 12 years, HT provides the best long-term survival benefit for heart failure patients whose life expectancy would otherwise be 6 to 24 months with medical therapy alone.

We evaluated 803 renal transplant recipients and correlated HLA-DR/DQ molecular mismatch alloimmune risk categories (low, intermediate, high) with the severity, frequency, and persistence of TCMR. Allograft survival was reduced in recipients with Banff Borderline (HR 2.4, p=0.003) and Banff ≥IA TCMR (HR 4.3, p less then 0.0001) including a subset who never developed de novo donor-specific antibodies (p=0.002). HLA-DR/DQ molecular mismatch alloimmune risk categories were multivariate correlates of Banff Borderline and Banff ≥IA TCMR and correlated with the severity and frequency of rejection episodes. Recipient age, HLA-DR/DQ molecular mismatch category, and cyclosporin versus tacrolimus immunosuppression were independent correlates of Banff Borderline and Banff ≥IA TCMR. In the subset treated with tacrolimus (720/803) recipient age, HLA-DR/DQ molecular mismatch category, and tacrolimus coefficient of variation were independent correlates of TCMR. The correlation of HLA-DR/DQ molecular mismatch category with TCMR, including Borderline, provides evidence for their alloimmune basis. HLA-DR/DQ molecular mismatch may represent a precise prognostic biomarker that can be applied to tailor immunosuppression or design clinical trials based on individual patient risk.

Here, we developed an integrative framework and synthesized data from 256 studies of intraguild predation, scavenging, kleptoparisitism and resource availability to examine global patterns of suppression and facilitation. Large carnivores were responsible for one third of mesocarnivore mortality (n = 1,581 individuals), and intraguild mortality rates were superadditive, increasing from 10.6% to 25.5% in systems with two vs. three large carnivores. Scavenged ungulates comprised 30% of mesocarnivore diets, with larger mesocarnivores relying most heavily on carrion. Large carnivores provided 1,351 kg of carrion per individual per year to scavengers, and this subsidy decreased at higher latitudes. However, reliance on carrion by mesocarnivores remained high, and abundance correlations among sympatric carnivores were more negative in these stressful, high-latitude systems. Carrion provisioning by large carnivores may therefore enhance suppression rather than benefiting mesocarnivores. These findings highlight the synergistic effects of scavenging and predation risk in structuring carnivore communities, suggesting that the ecosystem service of mesocarnivore suppression provided by large carnivores is strong and not easily replaced by humans. © 2020 John Wiley & Sons Ltd/CNRS.BACKGROUND Inadvertent intra-arterial injection of dermal fillers including calcium hydroxylapatite (CaHA) can result in serious adverse events including soft tissue necrosis, permanent scarring, visual impairment, and blindness. When intra-arterial injection occurs, immediate action is required for optimal outcomes, but the infrequency of this event means that many physicians may never have experienced this scenario. The aim of this document is to provide evidence-based and expert opinion recommendations for the recognition and management of vascular compromise following inadvertent injection of CaHA. METHODS An international group of experts with experience in injection of CaHA and management of vascular complications was convened to develop a consensus on the optimal management of vascular compromise following intra-arterial CaHA injection. The consensus members were asked to provide preventative advice for the avoidance of intravascular injection and to produce a treatment protocol for acute and delayed pc experts with the latest reports from the published literature to provide an up-to-date office-based protocol for the prevention and treatment of complications arising from intra-arterial CaHA injection. © 2020 The Authors. Journal of Cosmetic Dermatology published by Wiley Periodicals, Inc.The Banff Digital Pathology Working Group (DPWG) was formed in the time leading up to and during the joint American Society for Histocompatibility and Immunogenetics (ASHI)/Banff Meeting, September 23-27, 2019, held in Pittsburgh, Pennsylvania. At the meeting, the 14th Banff Conference, presentations directly and peripherally related to the topic of "digital pathology" were presented; and discussions before, during, and after the meeting have resulted in a list of issues to address for the DPWG. Included are practice standardization, integrative approaches for study classification, scoring of histologic parameters (e.g., interstitial fibrosis and tubular atrophy and inflammation), algorithm classification, and precision diagnosis (e.g., molecular pathways and therapeutics). Since the meeting, a survey with international participation of mostly pathologists (81%) was conducted, showing that whole slide imaging (WSI) is available at the majority of centers (71%) but that artificial intelligence (AI)/machine learning was only used in around 12% of centers, with a wide variety of programs/algorithms employed. Digitalization is not just an end in itself. It also is a necessary precondition for AI and other approaches. Discussions at the meeting and the survey highlight the unmet need for a Banff DPWG and point the way toward future contributions that can be made. This article is protected by copyright.

The discovery that CLAD can manifest both clinically and morphologically in vastly different ways led to the definition of distinct subtypes of CLAD. In this review, recent advances in our understanding of the pathophysiological mechanisms of the different phenotypes of CLAD will be discussed with a particular focus on tissue-based and molecular studies. An overview of the current knowledge on the mechanisms of the airway-centered bronchiolitis obliterans syndrome (BOS), as well as the airway and alveolar injuries in the restrictive allograft syndrome (RAS) and also the vascular compartment in chronic antibody mediated rejection is provided. Specific attention is also given to morphological and molecular markers for early CLAD diagnosis or histological changes associated with subsequent CLAD development. Evidence for a possible overlap between different forms of CLAD is presented and discussed. In the end, "tissue remains the (main) issue", as we are still limited in our knowledge about the actual triggers and specific mechanisms of all late forms of post-transplant graft failure, a shortcoming which needs to be addressed in order to further improve the outcome of lung transplant recipients.

Most crucially, the proposed rule included two new OPO performance metrics using objective, standardized data from the Centers for Disease Control and Prevention (CDC). These new metrics would employ a denominator that included inpatient deaths from certain causes that could lead to organ donation, rather than the current unverifiable eligible death metric. While there has been near-uniform support for replacing the eligible death denominator with CDC data, a source of contention is CMS's proposal to not risk adjust for race in their OPO outcome. Nonetheless, there have been calls for race and ethnicity to be included as risk adjusted variables in the CMS donation metric. Herein, we lay out an argument as to why inclusion of race and ethnicity as risk adjustment variables in an OPO performance metric is not only statistically suspect but will hide the inequities that are detrimental to optimal system performance and assurance that all patients have timely access to donation.

In 2014, we administered pembrolizumab (anti-PD-1) for ~9 months to a 57-year-old kidney transplant recipient with metastatic cutaneous squamous cell carcinoma (CSCC). The patient experienced both a complete anti-tumor response and T cell-mediated allograft rejection requiring reinitiation of hemodialysis. Four-and-a-half years after initiating pembrolizumab, the patient remained without evidence of CSCC relapse and received a kidney transplant from a living unrelated donor. Ten-and-a-half months after kidney retransplantation, the allograft is functioning well and the patient's CSCC remains in remission. This case illustrates the potential for PD-1 blockade to bring about durable immune-mediated tumor control in chronically-immunosuppressed patients, and begins to address the feasibility of kidney retransplantation in patients who have previously received immune checkpoint inhibitor therapy for cancer. Results from this and future cases may help elucidate mechanisms of anti-tumor immunity and allograft tolerance, and inform updates to transplant decision models. Our report also underscores the need for clinical trials testing novel immunotherapy combinations in solid organ transplant recipients designed to uncouple anti-tumor and anti-allograft immunity.

Protein microarray identified 366 non-HLA antibodies (>1.5 fold, p1R) with an area under the curve (AUC) of .87 (p less then 0.05) with 92.86% sensitivity and 66.67% specificity. We conclude that multiplex bead array assessment of non-HLA antibodies identifies cardiac transplant recipients at risk of rejection. This article is protected by copyright.
