Peritraumatic C-reactive protein levels predict pain outcomes following traumatic stress exposure in a sex-dependent manner.

Background: Chronic pain following traumatic stress exposure (TSE) is common. Increasing evidence suggests inflammatory/immune mechanisms are induced by TSE, play a key role in the recovery process versus development of post-TSE chronic pain, and are sex specific. In this study, we tested the hypothesis that the inflammatory marker C-reactive protein (CRP) is associated with chronic pain after TSE in a sex-specific manner.

Posterior hippocampal sparing in Lewy body disorders with Alzheimer's copathology: An in vivo MRI study.

Background: Lewy body disorders (LBD), encompassing Parkinson disease (PD), PD dementia (PDD), and dementia with Lewy bodies (DLB), are characterized by alpha-synuclein pathology but often are accompanied by Alzheimer's disease (AD) neuropathological change (ADNC). The medial temporal lobe (MTL) is a primary locus of tau accumulation and associated neurodegeneration in AD. However, it is unclear the extent to which AD copathology in LBD (LBD/AD+) contributes to MTL-specific patterns of degeneration.

Real-World and Clinical Trial Validation of a Deep Learning Radiomic Biomarker for PD-(L)1 Immune Checkpoint Inhibitor Response in Advanced Non-Small Cell Lung Cancer.

Purpose: This study developed and validated a novel deep learning radiomic biomarker to estimate response to immune checkpoint inhibitor (ICI) therapy in advanced non-small cell lung cancer (NSCLC) using real-world data (RWD) and clinical trial data.

Materials And Methods: Retrospective RWD of 1,829 patients with advanced NSCLC treated with PD-(L)1 ICIs were collected from 10 academic and community institutions in the United States and Europe. The RWD included data sets for discovery (Data Set A-Discovery, n = 1,173) and independent test (Data Set B, n = 458).

The C5a/C5aR1 axis promotes migration of tolerogenic dendritic cells to lymph nodes, impairing the anticancer immune response.

The precise mechanisms by which the complement system contributes to the establishment of an immunosuppressive tumor microenvironment (TME) and promotes tumor progression remain unclear. In this study, we investigated the expression and function of complement C5a receptor 1 (C5aR1) in human and mouse cancer-associated dendritic cells (DCs). First, we observed an overexpression of C5aR1 in tumor-infiltrating DCs, compared to DCs from blood or spleen.

Factors Associated With Return to Activity After Concussion Among Female Service Academy Members: Findings From the NCAA-DoD CARE Consortium.

Introduction: Service academy members are at high risk for concussions as a result of participation in both sports and military-specific training activities. Approximately 17% of active duty service members are female, and they face unique challenges in achieving timely recovery from concussions. Understanding the unique characteristics affecting return to unrestricted activity (RTA) among female service academy members is imperative for the ever-growing proportion of females across the U.

Intracisternal vs intraventricular injection of AAV1 result in comparable, widespread transduction of the dog brain.

Widespread distribution of transduced brain cells following delivery of AAV vectors into the cerebrospinal fluid (CSF) of the cisterna magna (CM) has been demonstrated in large animal brains. In humans, intraventricular injection is preferred to intracisternal injection for CSF delivery due to the risk of brain stem injury. One study in the dog reported adverse reactions to AAV vectors expressing GFP injected into the lateral ventricle but not when injected into the CM.

Current State of Community-Driven Radiological AI Deployment in Medical Imaging.

Artificial intelligence (AI) has become commonplace in solving routine everyday tasks. Because of the exponential growth in medical imaging data volume and complexity, the workload on radiologists is steadily increasing. AI has been shown to improve efficiency in medical image generation, processing, and interpretation, and various such AI models have been developed across research laboratories worldwide.

Larotrectinib for Newly Diagnosed Infantile Fibrosarcoma and Other Pediatric Fusion-Positive Solid Tumors (Children's Oncology Group ADVL1823).

Purpose: The TRK inhibitor larotrectinib is US Food and Drug Administration approved for fusion-positive solid tumors that lack a satisfactory alternative or have progressed after treatment but has not been systematically studied as a frontline therapy with a defined duration of treatment. ADVL1823 evaluated larotrectinib in patients with newly diagnosed fusion-positive solid tumors with response-adapted duration of therapy and local control.

Methods: Patients received larotrectinib twice daily in 28-day cycles for a predefined duration of treatment, ranging from 6 to 26 cycles depending on response to therapy and surgical resectability.

A Guideline-Directed Approach to Obesity Treatment.

This article summarizes and compares 18 sets of guidelines for adult obesity treatment, highlighting key recommendations for patient evaluation, lifestyle intervention, anti-obesity medications (AOMs), and metabolic and bariatric surgery. Guidelines are consistent in many regards, although there is divergence regarding preferred AOMs. Metabolic and bariatric surgery is still recognized as the most durable form of obesity treatment, and newer guidelines suggest these procedures at lower BMI thresholds for people with uncontrolled type 2 diabetes.

Implementing Precision Medicine for Dilated Cardiomyopathy: Insights from The DCM Consortium.

Background: Clinical genetic evaluation of dilated cardiomyopathy (DCM) is implemented variably or not at all. Identifying needs and barriers to genetic evaluations will enable strategies to enhance precision medicine care.

Methods: An online survey was conducted in June 2024 among cardiologist investigators of the DCM Consortium from US advanced heart failure/transplant (HF/TX) programs to collect demographics, training, program characteristics, genetic evaluation practices for DCM, and implementation needs.

Understanding and addressing mental health challenges of families admitted to the neonatal intensive care unit.

This article reviews the psychological distress experienced by NICU families, including anxiety, postpartum depression (PPD), and post-traumatic stress disorder (PTSD), in addition to providing recommendations for clinicians at the individual, institutional, and national level. Currently, mental health screenings, specialized evaluations, and treatment options are not routinely offered to NICU families and are frequently under-utilized when offered. Here we provide expert opinion recommendations to address challenges in supporting universal screening, offering bedside interventions, including trained mental health professionals in care plans, updating neonatology training competencies, and advocating for policies that support the mental health of NICU families.

EZH2 inhibition enhances T cell immunotherapies by inducing lymphoma immunogenicity and improving T cell function.

T cell-based immunotherapies have demonstrated effectiveness in treating diffuse large B cell lymphoma (DLBCL) and follicular lymphoma (FL) but predicting response and understanding resistance remains a challenge. To address this, we developed syngeneic models reflecting the genetics, epigenetics, and immunology of human FL and DLBCL. We show that EZH2 inhibitors reprogram these models to re-express T cell engagement genes and render them highly immunogenic.

A comparative analysis of microsurgical resection versus stereotactic radiosurgery for Spetzler-Martin grade III arteriovenous malformations: A multicenter propensity score matched study.

Background: Spetzler-Martin (SM) Grade III brain arteriovenous malformations (BAVMs) represent a transitional risk zone between low- and high-grade BAVMs, characterized by diverse angioarchitecture. The primary treatment options are endovascular embolization, microsurgical resection (MS), and stereotactic radiosurgery (SRS). This study compares the efficacy and outcomes of MS and SRS.

Tbx1 haploinsufficiency leads to local skull deformity, paraflocculus and flocculus dysplasia, and motor-learning deficit in 22q11.2 deletion syndrome.

Neurodevelopmental disorders are thought to arise from intrinsic brain abnormalities. Alternatively, they may arise from disrupted crosstalk among tissues. Here we show the local reduction of two vestibulo-cerebellar lobules, the paraflocculus and flocculus, in mouse models and humans with 22q11.

Dual pathways of concealed gun carrying and use from adolescence to adulthood over a 25-year era of change.

Most homicides in the United States are committed using a handgun, but little research examines gun carrying over critical stages of the life course and changing contexts of violence. Notably, although most of the handgun homicides are committed by adults, most research on concealed gun carrying focuses on adolescents in single cohort studies. Using more than 25 years of longitudinal multicohort data from Chicago, 1994-2021, we show that pathways of concealed gun carrying are distinct between adolescence and adulthood.

Pexidartinib and standard neoadjuvant therapy in the adaptively randomized I-SPY2 trial for early breast cancer.

Purpose: We investigated the small-molecule receptor tyrosine kinase-inhibitor of colony-stimulating factor-1 receptor pexidartinib in the stage II/III breast cancer in the I-SPY2 platform trial.

Methods: I-SPY2 is an adaptive platform trial that features multiple arms of experimental agents administered on a background of standard neoadjuvant therapy with paclitaxel and adriamycin/cyclophosphamide, followed by definitive surgery. The adaptive randomization engine preferentially assigns patients based upon cumulative performance of each agent in a given breast cancer subtype based on hormone receptor and HER2 receptor status.
