On the Role of Epigenetic Modifications of HPA Axis in Post Traumatic Stress Disorder (PTSD) and Resilience.

Stress is a fundamental adaptive response mediated by the amygdala and Hypothalamus-Pituitary-Adrenal (HPA) axis. Extreme or chronic stress, however, can result in a multitude of neuropsychiatric disorders, including anxiety, paranoia, bipolar disorder (BP), major depressive disorder (MDD), and Post-Traumatic Stress Disorder (PTSD). Despite widespread exposure to trauma (70.

Loneliness mediates the association between trait social anxiety and cardiovascular reactivity to acute psychological stress.

The primary aims of the current study are (1) to examine the association between trait social anxiety and cardiovascular reactivity to acute psychological stress, and (2) to identify if loneliness significantly mediates the association between trait social anxiety and cardiovascular reactivity. A sample of 658 participants completed a cardiovascular reactivity protocol consisting of a resting baseline and stressor phase (mental arithmetic and Stroop), with systolic blood pressure (SBP), diastolic blood pressure (DBP) and heart rate (HR) monitored throughout. Participants also completed self-reported measures assessing social anxiety and loneliness.

Assessing microplastic and nanoplastic contamination in bird lungs: evidence of ecological risks and bioindicator potential.

Microplastics (MPs, 1 µm-5 mm) and nanoplastics (NPs, < 1 µm), collectively termed micro(nano)plastics (MNPs), are pervasive airborne pollutants with significant ecological risks. Birds, recognized as bioindicators, are particularly vulnerable to MNP exposure, yet the extent and risks of MNP pollution in bird lungs remain largely unexplored. This study assessed MP exposure in bird lungs of 51 species and NP exposure in the lungs of five representative species using laser direct infrared (LDIR) and pyrolysis gas chromatography-mass spectrometry (Py-GC-MS) techniques, respectively.

Comparison of Pediatric and Adult Firearm Deaths to Inform Violence Prevention at Pediatric Trauma Centers.

Introduction: Hospital-based violence intervention programs primarily target adults, raising questions about the effectiveness in preventing pediatric firearm deaths. We hypothesized that pediatric and adult firearm injury deaths are different enough to require unique intervention strategies.

Methods: Retrospective chart review was conducted of medical examiner and trauma center records of firearm-related deaths in the largest metropolitan county in Texas.

Discrimination of Radiologists' Experience Level Using Eye-Tracking Technology and Machine Learning: Case Study.

Background: Perception-related errors comprise most diagnostic mistakes in radiology. To mitigate this problem, radiologists use personalized and high-dimensional visual search strategies, otherwise known as search patterns. Qualitative descriptions of these search patterns, which involve the physician verbalizing or annotating the order he or she analyzes the image, can be unreliable due to discrepancies in what is reported versus the actual visual patterns.

Efficacy of lactoferrin supplementation in pediatric infections: A systematic review and meta-analysis.

Pediatric infections account for approximately one-third of all deaths in children under 5 globally. Lactoferrin (LF) supplementation has the potential to reduce infection-related morbidity due to its antimicrobial, anti-inflammatory and immunoregulatory properties. We conducted a systematic review and meta-analysis of oral LF supplementation randomized controlled trials (RCT) in population under 18 years old.

Pediatric relapsed/refractory ALK+ anaplastic large cell lymphoma treatment and outcomes in the targeted drug era.

Treatment options for patients with relapsed or refractory (R/R) anaplastic large cell lymphoma (ALCL) have increased in the era of targeted therapies such as brentuximab vedotin (BV) and Anaplastic Lymphoma Kinase (ALK) inhibitors. However, there is no standard treatment and limited published data evaluating their use. The goal of this retrospective study is to describe current real-world treatment and outcomes of pediatric, adolescent, and young adult patients with R/R ALK-positive ALCL.

Updating US Public Health For Healthier Communities.

The United States faces urgent public health challenges, including high preventable death rates, pervasive health disparities, and emerging health risks, despite unprecedented medical progress. This article, part of the National Academy of Medicine's Vital Directions for Health and Health Care: Priorities for 2025 initiative, presents a vision for modernizing the US public health system to address these twenty-first-century challenges through federally supported partnerships with health care, social services, and community organizations. We identify actions to address persistent public health challenges that stem from insufficient and fragmented funding models, inadequate data infrastructure, workforce vulnerabilities, and limited public trust.

Four Opportunities To Revitalize The US Biomedical Research Enterprise.

The US biomedical research enterprise is renowned for its historical and ongoing scientific breakthroughs and advancements. Yet its capacity to solve complex health issues, bridge health equity gaps, and strengthen public trust is constrained by the lack of an overarching national vision, fragmented coordination for research funding, and critical workforce recruitment and retention challenges. To improve national health outcomes and retain global competitiveness, the sector must embrace new approaches.

Human Epidermal Growth Factor Receptor 2 Loss Following Treatment with Trastuzumab Deruxtecan in Patients with Metastatic Breast Cancer.

Purpose: Trastuzumab deruxtecan (T-DXd) is currently approved for treating metastatic breast cancer (MBC) which is HER2-positive (immunohistochemistry [IHC] score of 3+ or ISH positivity) or HER2-low (IHC score of 1+ or IHC 2+/ISH negative), as well as for HER2-positive gastric cancer, HER2-mutant lung cancer, and HER2 overexpressing solid tumors. Given the increasing utilization of T-DXd, we sought to determine how HER2 receptor status might change following T-DXd therapy.

Design: We retrospectively reviewed patients with MBC who received T-DXd at The University of Texas MD Anderson Cancer Center.

Functional classification of tauopathy strains reveals the role of protofilament core residues.

Distinct tau amyloid assemblies underlie diverse tauopathies but defy rapid classification. Cell and animal experiments indicate tau functions as a prion, as different strains propagated in cells cause unique, transmissible neuropathology after inoculation. Strain amplification requires compatibility of the monomer and amyloid template.

Prefrontal 5α-reductase 2 mediates male-specific acute stress response.

A key response to acute stress is the increased brain synthesis of the neurosteroid allopregnanolone (AP). Although the rate-limiting step of this reaction is catalyzed by 5α-reductase (5αR), the role of its two primary isoenzymes, 5αR1 and 5αR2, in stress reactivity remains unclear. Here, we found that acute stress led to increased levels of 5αR2, but not 5αR1, in the medial prefrontal cortex (mPFC) of male, but not female, rats.
