Donor hepatitis C status is not associated with an increased risk of acute rejection in kidney transplantation.

Introduction: In renal transplantation, donor hepatitis C virus (HCV) status is crucial to consider when selecting a recipient given the high likelihood of transmission. We analyzed the effect of donor HCV status on post-renal transplant rejection and virologic infectious outcomes using electronic health record data from multiple US health care organizations.

Methods: Using real world data from electronic health records of renal transplant recipients, a propensity score-matched case-control study of one-year renal transplant outcomes was conducted on cohorts of HCV-negative recipients who received an organ from an HCV-positive donor (HCV D+/R-) versus from an HCV-negative donor (HCV D-/R-).

Hepatic and pulmonary macrophage activity in a mucosal challenge model of Ebola virus disease.

Background: The inflammatory macrophage response contributes to severe Ebola virus disease, with liver and lung injury in humans.

Objective: We sought to further define the activation status of hepatic and pulmonary macrophage populations in Ebola virus disease.

Methods: We compared liver and lung tissue from terminal Ebola virus (EBOV)-infected and uninfected control cynomolgus macaques challenged via the conjunctival route.

Precision in Immune Management: Balancing Steroid Exposure, Rejection Risk, and Infectious Outcomes in Adult Kidney Transplant Recipients.

Background/objectives: With kidney transplant immunosuppression, physicians must balance preventing rejection with minimizing infection and malignancy risks. Steroids have been a mainstay of these immunosuppression regimens since the early days of kidney transplantation, yet their risks remain debated. Our study looks at the clinical outcomes of patients undergoing early steroid withdrawal (ESW) vs.

A Comparison of Delivery Modalities for Pregnancy Clinical Care Management: Telephonic Versus Video.

Objective: Given the high prevalence of maternal morbidity and mortality, it is imperative that maternal health interventions are comprehensively evaluated, so they can be scaled with fidelity. Community-based care management models focused on perinatal health care are a priority for health care systems and payers. Alternative care management delivery modalities, such as video visits, are needed to expand program reach amidst growing system-level challenges.

Network analysis of ethnic-racial socialization competency and content among diverse parents of color: An eye toward intervention targets.

To help their children survive and thrive in our unequal society, parents of color must engage in the process of ethnic-racial socialization (ERS) or teaching about race, ethnicity, and racism. Equally important to the provision of ERS messages are parents' confidence, skills, and stress levels around delivering ERS (i.e.

Enhancing Oral Cancer Detection: A Systematic Review of the Diagnostic Accuracy and Future Integration of Optical Coherence Tomography with Artificial Intelligence.

: Optical Coherence Tomography (OCT) has emerged as an important imaging modality in non-invasive diagnosis for oral cancer and can provide real-time visualisation of tissue morphology with the required high resolution. This systematic review aims to assess the diagnostic accuracy of OCT in the detection of oral cancers, and to explore the potential integration of OCT with artificial intelligence (AI) and other imaging techniques to enhance diagnostic precision and clinical outcomes in oral healthcare. : A systematic literature search was conducted across PubMed, Embase, Scopus, Google Scholar, Cochrane Central Register, and Web of Science from inception until August 2024.

Antibody-Mediated Rejection in Liver Transplantation: Immuno-Pathological Characteristics and Long-Term Follow-Up.

The diagnosis of liver antibody-mediated rejection (AMR) is challenging and likely under-recognized. The association of AMR with donor-specific antibodies (DSA), and its clinical course in relation to pathologic findings and treatment are ill defined. We identified cases of liver AMR by following the criteria outlined by the 2016 Banff Working Group.

Protection against fibrosis by a bacterial consortium in metabolic dysfunction-associated steatohepatitis and the role of amino acid metabolism.

The gut microbiota drives progression to liver fibrosis, the main determinant of mortality in metabolic dysfunction-associated steatohepatitis (MASH). In this study, we aimed to identify bacterial species associated with protection against liver fibrosis in a high-risk population, and test their potential to protect against liver fibrosis . Based on stool shotgun metagenomic sequencing of 340 subjects from a population cohort disproportionally affected by MASH, we identified bacterial species from the and orders associated with reduced risk of liver fibrosis.

Invention of novel 3-aminopiperidin-2-ones as calcitonin gene-related peptide receptor antagonists.

A novel series of 3-amino-piperidin-2-one-based calcitonin gene-related peptide (CGRP) receptor antagonists was invented based upon the discovery of unexpected structure-activity observations. Initial exploration of the structure-activity relationships enabled the generation of a moderately potent lead structure (4). A series of modifications, including ring contraction and inversion of stereocenters, led to surprising improvements in CGRP receptor affinity.

Nicotinamide N-methyltransferase inhibition mitigates obesity-related metabolic dysfunction.

Aim: To assess the effects of a small-molecule nicotinamide N-methyltransferase (NNMT) inhibitor, 5A1MQ, on body composition, metabolic variables, fatty liver pathologies, and circulating biomarkers in diet-induced obese (DIO) mice, and characterize its plasma pharmacokinetics (PK) and tissue distribution in vivo.

Materials And Methods: DIO mice were administered vehicle or 5A1MQ once daily for 28 days. Longitudinal measures of body composition, blood glucose and plasma insulin levels, and terminal measures of liver histopathology and serum markers, were evaluated.

A challenging case of eosinophilic myocarditis leading to heart failure and transplantation.

The large spectrum of etiologies, severities, and histologic appearances of eosinophilic myocarditis (EoM) poses challenges to its diagnosis and management. Endomyocardial biopsy is the current gold standard for diagnosis. However, cardiovascular magnetic resonance imaging is becoming more frequently used to diagnose acute myocarditis because of enhanced sensitivity when compared to histopathologic examination, and its less invasive nature.

The learning curve of COVID-19 and organ donation: Potential missed opportunities in the COVID era.

Background: Early in the COVID-19 pandemic, positive COVID-19 status often disqualified potential organ donors due to perceived risks, despite limited evidence. Subsequent studies have clarified that the COVID-19 status of donors, particularly when incidental and not the cause of death, does not adversely affect non-lung transplant outcomes. This study quantifies the potential loss of eligible organ donors and the corresponding impact on organ availability during the initial phase of the pandemic.

Disparate outcomes in Hispanic patients with metabolic dysfunction-associated steatotic liver disease/steatohepatitis and type 2 diabetes: Large cohort study.

Background: Metabolic dysfunction-associated steatotic liver disease (MASLD) and metabolic dysfunction-associated steatohepatitis (MASH) are a growing health burden across a significant portion of the global patient population. However, these conditions seem to have disparate rates and outcomes between different ethnic populations. The combination of MASLD/MASH and type 2 diabetes increases the risk of hepatocellular carcinoma (HCC), and Hispanic patients experience the greatest burden, particularly those in South Texas.

Kupffer cell diversity maintains liver function in alcohol-associated liver disease.

Background And Aims: Liver macrophages are heterogeneous and play an important role in alcohol-associated liver disease (ALD) but there is limited understanding of the functions of specific macrophage subsets in the disease. We used a Western diet alcohol (WDA) mouse model of ALD to examine the hepatic myeloid cell compartment by single cell RNAseq and targeted KC ablation to understand the diversity and function of liver macrophages in ALD.

Approach And Results: In the WDA liver, KCs and infiltrating monocytes/macrophages each represented about 50% of the myeloid pool.

Beyond prevention: Unveiling the benefits of triple vaccination on COVID-19 severity and resource utilization in solid organ transplant recipients.

Objective: Despite the widespread reduction in COVID-19-related morbidity and mortality attributed to vaccination in the general population, vaccine efficacy in solid organ transplant recipients (SOTR) remains under-characterized. This study aimed to investigate clinically relevant outcomes on double and triple-vaccinated versus unvaccinated SOTR with COVID-19.

Study Design And Setting: A retrospective propensity score-matched cohort study was performed utilizing data from the US Collaborative Network Database within TriNetX (n = 117,905,631).

We got this: Evaluating racial socialization competency among diverse ethnic-racial groups.

Historically, research on racial socialization (RS) has centered on frequency, beliefs, and content of parent-child communications, with varied applications and implications across racial and ethnic subgroups. The Racial Socialization Competency Scale (RaSCS; Anderson et al., 2020) was developed to assess three dimensions of a novel construct, RS competency (confidence, skills, stress), among Black caregivers.

Differences and similarities between ethnic-racial identity and critical consciousness links among diverse parents of color.

Parents of color's critical consciousness development (understanding of and actions to redress societal inequalities) is an important yet understudied area, especially relative to the burgeoning literature on youth's critical consciousness development. As with youth of color, ethnic-racial identity, or the meaning and importance placed on one's ethnic-racial group membership, likely plays a notable yet complex role in parents' critical consciousness. Specifically, parents' participation in activities that engage them in the culture of their racial-ethnic group (exploration), the importance they place on race-ethnicity (centrality), and their perceptions of how society views their group (public regard) may each be differentially associated with understanding of inequalities (critical reflection), motivation toward ending inequalities (critical motivation), and the behaviors parents engage in to address inequalities (critical action).

Arrhythmias and cardiac MRI associations in patients with established cardiac dystrophinopathy.

Aims: Some patients with cardiac dystrophinopathy die suddenly. Whether such deaths are preventable by specific antiarrhythmic management or simply indicate heart failure overwhelming medical therapies is uncertain. The aim of this prospective, cohort study was to describe the occurrence and nature of cardiac arrhythmias recorded during prolonged continuous ECG rhythm surveillance in patients with established cardiac dystrophinopathy and relate them to abnormalities on cardiac MRI.

RECASTing racial coping stress in school: Self-efficacy as buffer for adolescent agency.

Objective: The consequences of racism and racial stress on the academic and social well-being of adolescents are profound and well-documented. However, our understanding of how adolescents navigate racial stress and develop the agency to address discriminatory encounters, particularly in settings where educators struggle to intervene with microaggressions, remains limited. Research into the development of racial coping self-efficacy (RCSE) and coping skills has shown promise in enhancing the overall well-being of youth.

Mental Health Polypharmacy in "Non-Coded" Primary Care Patients: The Effect of Deprescribing.

: Mental health (MH) polypharmacy, defined as prescribing multiple mental health medications for the same condition, presents significant challenges in clinical practice. With varying prevalence rates and an increasing trend, particularly in the UK, this deprescribing prospective quality improvement project aimed to address the complexities and risks associated with MH polypharmacy. : A large primary care centre in London was selected for this project.
