Pediatric liver retransplantation (rLT) has historically shown poorer outcomes compared to primary liver transplantation (pLT). Comprehensive studies assessing outcomes for pediatric rLT candidates under the modern allocation policy are lacking. OPTN data from January 1, 2010, to December 31, 2022 were obtained; exclusion criteria included candidates ≥18years of age and those listed or transplanted for multiple organs.

Background And Aims: We sought to develop a minimally-invasive, robust, accessible nonendoscopic strategy to diagnose Barrett's esophagus (BE), esophageal adenocarcinoma (EAC), and its immediate precursor lesion, high-grade dysplasia (HGD) based on methylated DNA biomarkers applied to a retrievable sponge-capsule device in a cohort representative of the BE population (i.e., mostly short-segment, non-dysplastic BE, NDBE).

The current study investigated the relationship between adverse childhood experiences (ACEs), post-traumatic stress disorder (PTSD) symptoms, within-network resting-state functional connectivity (rs-FC), and alcohol use during adolescence using functional magnetic resonance imaging (fMRI) data from the National Consortium on Alcohol and Neurodevelopment in Adolescence study (NCANDA;  = 687). Significant rs-FC differences emerged that linked participant ACEs, PTSD symptoms, and alcohol use problems. Participants with ACEs compared to those without had diminished rs-FC within the default mode, salience, and medial frontoparietal networks ( ≤ 0.

Clinical and Programmatic Considerations for Enhancing Developmentally Informed Care in Psychosis Risk Programs for Youths.

Psychiatr Serv

January 2025

Department of Psychiatry (all authors), University of Pittsburgh School of Medicine, and Department of Psychology (Bylsma), University of Pittsburgh, Pittsburgh.

A national and global focus on expanding identification and treatment of youths who are at clinical high risk for psychosis (CHR-P) highlights an urgent need to develop clinical services for this population; however, questions remain regarding program structures and treatment approaches in CHR-P clinics. The authors of this Open Forum expand on previous recommendations and argue that a focus on enhancing developmentally informed care should serve as a central principle for structuring macrolevel service policies and programs as well as person-specific treatment approaches. The authors discuss developmental considerations in program planning and service provision and offer recommendations for providers and other stakeholders to enhance developmentally informed care for individuals at CHR-P.

Abnormal tau phosphorylation is a key mechanism in neurodegenerative diseases. Evidence implicates infectious agents, such as Herpes Simplex Virus 1 (HSV-1), as co-factors in the onset or the progression of neurodegenerative diseases, including Alzheimer's disease. This has led to divergence in the field regarding the contribution of viruses in the etiology of neurodegenerative diseases.

Amyotrophic lateral sclerosis (ALS) is a devastating neurodegenerative disorder typically characterized by insoluble inclusions of hyperphosphorylated TDP-43. The mechanisms underlying toxic TDP-43 accumulation are not understood. Persistent activation of p38 mitogen-activated protein kinase (MAPK) is implicated in ALS.

Introduction: Young childbearing sexual minority (SM) people are more likely to use cannabis and to have an unintended pregnancy than their heterosexual peers; however, little is known about their perceptions and experiences of peripartum cannabis use. This qualitative study explores the relationships young pregnant and parenting SM people have with cannabis, as well as their feelings and opinions about prenatal cannabis use.

Method: Participants who identified as SM from baseline surveys of the YoungMoms study were recruited for semi-structured qualitative interviews (n = 13).

IP-to-MS: An Unbiased Workflow for Antigen Profiling.

J Proteome Res

January 2025

Impact Proteomics, LLC., Pittsburgh, Pennsylvania 15206, United States.

Immunoprecipitation is among the most widely utilized methods in biomedical research, with applications that include the identification of antibody targets and associated proteins. The path to identifying these targets is not straightforward, however, and often requires the use of chemical cross-linking and/or gel electrophoresis to separate targets from an overabundance of immunoglobulin protein. Such experiments are labor intensive and often yield long lists of candidate antibody targets.

User adherence contributes to the effectiveness of topical pre-exposure prophylactic products designed to protect against human immunodeficiency virus type 1 (HIV-1) infection. Long-acting approaches that do not require daily or coitally-dependent use could potentially improve user adherence. This study aims to develop a long-acting vaginal film to deliver an integrase inhibitor, MK-2048, for prevention of HIV-1 infection.

Background: Patients with human epidermal growth factor receptor 2 (HER2)-positive early breast cancer with residual invasive disease after neoadjuvant systemic therapy have a high risk of recurrence and death. The primary analysis of KATHERINE, a phase 3, open-label trial, showed that the risk of invasive breast cancer or death was 50% lower with adjuvant trastuzumab emtansine (T-DM1) than with trastuzumab alone.

Methods: We randomly assigned patients with HER2-positive early breast cancer with residual invasive disease in the breast or axilla after neoadjuvant systemic treatment with taxane-based chemotherapy and trastuzumab to receive T-DM1 or trastuzumab for 14 cycles.

Targeting TRPC channels for control of arthritis-induced bone erosion.

Sci Adv

January 2025

Fels Cancer Institute for Personalized Medicine, Department of Cancer & Cellular Biology, Lewis Katz School of Medicine at Temple University, Philadelphia, PA 19140, USA.

Arthritis leads to bone erosion due to an imbalance between osteoclast and osteoblast function. Our prior investigations revealed that the Ca-selective ion channel, Orai1, is critical for osteoclast maturation. Here, we show that the small-molecule ELP-004 preferentially inhibits transient receptor potential canonical (TRPC) channels.

Background: The challenges associated with traditional drug screening, such as high costs and long screening times, have led to an increase in the use of single-cell isolation technologies. Small sample volumes are required for high-throughput, cell-based assays to reduce assay costs and enable rapid sample processing. Using microfluidic chips, single-cell analysis can be conducted more effectively, requiring fewer reagents and maintaining biocompatibility.

Background And Objectives: Despite growing interest in how patient frailty affects outcomes (eg, in neuro-oncology), its role after transsphenoidal surgery for Cushing disease (CD) remains unclear. We evaluated the effect of frailty on CD outcomes using the Registry of Adenomas of the Pituitary and Related Disorders (RAPID) data set from a collaboration of US academic pituitary centers.

Methods: Data on consecutive surgically treated patients with CD (2011-2023) were compiled using the 11-factor modified frailty index.

Background: Pediatric respiratory syncytial virus (RSV)-related acute lower respiratory tract infection (LRTI) commonly requires hospitalization. The Clinical Progression Scale Pediatrics (CPS-Ped) measures level of respiratory support and degree of hypoxia across a range of disease severity, but it has not been applied in infants hospitalized with severe RSV-LRTI.

Methods: We analyzed data from a prospective surveillance registry of infants hospitalized for RSV-related complications across 39 U.

Structural, architectural, contractile or electrophysiological alterations may occur in the left atrium (LA). The concept of LA cardiopathy is supported by accumulating scientific evidence demonstrating that LA remodeling has become a cornerstone diagnostic and prognostic marker. The structure and the function of LA and left atrial appendage (LAA) which is an integral part of the LA, are key elements for a better understanding of multiple clinical conditions, most notably atrial fibrillation (AF), cardioembolism, heart failure and mitral valve diseases.
