Convergent and Discriminant Validity of the Blast Exposure Threshold Survey in United States Military Service Members and Veterans.

The Blast Exposure Threshold Survey (BETS) is a recently developed and promising new self-report measure of lifetime blast exposure (LBE). However, there are no studies that have examined the psychometric properties of the BETS, which currently limits its clinical utility. The purpose of this study was to examine the convergent and discriminant validity of the BETS by comparing the BETS Generalized Blast Exposure Value (GBEV) to six variables hypothesized to be associated with LBE (i.

Gender Disparity of First Authors in Review Article Publications Related to Schizophrenia.

Schizophrenia is a severe psychotic condition that can be diagnosed when certain symptoms, such as disorganized speech, disorganized thoughts, or negative feelings, are present for at least six months in a person's life. Gender equity and representation in academic writing are significant issues that have received more attention recently. Understanding the gender discrepancies in authorship can help researchers studying schizophrenia overcome obstacles and potential biases.

Neonatal di-(2-ethylhexyl)phthalate exposure induces permanent alterations in secretory CRH neuron characteristics in the hypothalamus paraventricular region of adult male rats.

Corticotrophin-releasing hormone (CRH) neurons in the hypothalamic paraventricular nucleus (PVN) play a critical role in the modulation of the hypothalamic-pituitary-adrenal (HPA) axis. Early-life exposure to di-(2-ethylhexyl) phthalate (DEHP) has been associated with an increased risk of developing psychiatric disorders in adulthood. The present work was designed to explore the impact of neonatal exposure to DEHP on adult PVN CRH neuronal activity.

Pharmacology in Treatment of Patients with Disorders of Consciousness.

Pharmacologic treatment of disorders of consciousness remains a critical but challenging task for clinicians. Amantadine has been shown to promote the rate of neurologic recovery for patients with traumatic disorders of consciousness when administered between 4 and 16 weeks, as demonstrated by a well-designed randomized control trial. While there are no large, randomized controlled trials to support the use of other dopaminergic medicines (bromocriptine, levodopa, apomorphine), there is a large body of literature implicating their role in improving alertness and responsiveness in disorders of consciousness.

AEP-cleaved DDX3X induces alternative RNA splicing events to mediate cancer cell adaptation in harsh microenvironments.

Oxygen and nutrient deprivation are common features of solid tumors. Although abnormal alternative splicing (AS) has been found to be an important driving force in tumor pathogenesis and progression, the regulatory mechanisms of AS that underly the adaptation of cancer cells to harsh microenvironments remain unclear. Here, we found that hypoxia- and nutrient deprivation-induced asparagine endopeptidase (AEP) specifically cleaved DDX3X in a HIF1A-dependent manner.

The Impact of Lifetime Traumatic Brain Injury (TBI) on Mental Health Symptoms among Service Members in Interdisciplinary TBI Programs.

Introduction: Traumatic brain injury (TBI) is highly prevalent among active duty service members (ADSMs) and imposes a significant health burden, particularly on mental health (e.g., post-traumatic stress disorder [PTSD] and depressive symptoms).

Longitudinal health-related quality of life in military caregivers no longer providing care.

Purpose/objective: To examine health-related quality of life (HRQOL) in caregivers when providing care and no longer providing care to service members/veterans with traumatic brain injury.

Research Method/design: Participants included 466 caregivers enrolled in a 15-year longitudinal study. During an annual follow-up evaluation, a subsample of caregivers self-identified as no longer providing care and were retained in the study as a No Longer Caregiving group ( = 48).

Exploration of eye movement desensitization and reprocessing in treating posttraumatic stress-disorder in patients with acquired brain injury: a retrospective case series.

Posttraumatic stress disorder (PTSD) is prevalent in people with acquired brain injury (ABI). Despite the established efficacy of eye movement desensitization and reprocessing (EMDR) for PTSD in general, evaluation studies on EMDR in ABI patients with PTSD are limited. The aim of this study is to explore clinical features, treatment characteristics, feasibility and first indications of efficacy of EMDR in adult ABI patients with PTSD.

Socio-demographic determinants of intimate partner violence in Angola: a cross-sectional study of nationally representative survey data.

Intimate Partner Violence (IPV) is a global problem of public health importance, which can be found across all social layers and cultural backgrounds worldwide. Angola is still an under-explored country in the context of domestic violence and was therefore chosen as our focus of interest. Our study's goal was to identify the socio-demographic determinants of IPV in Angola.

White Matter Organization and Cortical Thickness Differ Among Active Duty Service Members With Chronic Mild, Moderate, and Severe Traumatic Brain Injury.

This study compared findings from whole-brain diffusion tensor imaging (DTI) and volumetric magnetic resonance imaging (MRI) among 90 Active Duty Service Members with chronic mild traumatic brain injury (TBI;  = 52), chronic moderate-to-severe TBI ( = 17), and TBI-negative controls ( = 21). Data were collected on a Philips Ingenia 3T MRI with DTI in 32 directions. Results demonstrated that history of TBI was associated with differences in white matter microstructure, white matter volume, and cortical thickness in both mild TBI and moderate-to-severe TBI groups relative to controls.

Novel Bimolecular Fluorescence Complementation (BiFC) Assay for Visualization of the Protein-Protein Interactions and Cellular Protein Complex Localizations.

Investigations of protein-protein interactions (PPIs) are of paramount importance for comprehending cellular processes within biological systems. The bimolecular fluorescence complementation (BiFC) assay presents a convenient methodology for visualizing PPIs within live cells. While a range of fluorescent proteins have been introduced into the BiFC system, there is a growing demand for new fluorescent proteins to accommodate the expanding requirements of researchers.

CHRM3 is a novel prognostic factor of poor prognosis and promotes glioblastoma progression via activation of oncogenic invasive growth factors.

Glioblastoma (GBM) is the most aggressive cancer of the brain and has a high mortality rate due to the lack of effective treatment strategy. Clarification of molecular mechanisms of GBM's characteristic invasive growth is urgently needed to improve the poor prognosis. Single-nuclear sequencing of primary and recurrent GBM samples revealed that levels of M3 muscarinic acetylcholine receptor (CHRM3) were significantly higher in the recurrent samples than in the primary samples.

Outlier Analysis for Acute Blood Biomarkers of Moderate and Severe Traumatic Brain Injury.

Blood biomarkers have been studied to improve the clinical assessment and prognostication of patients with moderate-severe traumatic brain injury (mo/sTBI). To assess their clinical usability, one needs to know of potential factors that might cause outlier values and affect clinical decision making. In a prospective study, we recruited patients with mo/sTBI ( = 85) and measured the blood levels of eight protein brain pathophysiology biomarkers, including glial fibrillary acidic protein (GFAP), S100 calcium-binding protein B (S100B), neurofilament light (Nf-L), heart-type fatty acid-binding protein (H-FABP), interleukin-10 (IL-10), total tau (T-tau), amyloid β40 (Aβ40) and amyloid β42 (Aβ42), within 24 h of admission.

Late Blood Levels of Neurofilament Light Correlate With Outcome in Patients With Traumatic Brain Injury.

Neurofilament light (NF-L) is an axonal protein that has shown promise as a traumatic brain injury (TBI) biomarker. Serum NF-L shows a rather slow rise after injury, peaking after 1-2 weeks, although some studies suggest that it may remain elevated for months after TBI. The aim of this study was to examine if plasma NF-L levels several months after the injury correlate with functional outcome in patients who have sustained TBIs of variable initial severity.
