Controlled chaos: Examining collaborative response to the 2017 Hattiesburg Tornado.

Hattiesburg, Mississippi experienced two tornados within a four-year span (2013-2017). Community members who participated in response and recovery to both disasters were interviewed to understand how coordination changed between the two events. The purposive sample included representatives from a variety of organizational types, sizes, and missions.

Accelerated epigenetic aging and prospective morbidity and mortality among U.S. veterans.

Epigenetic measures of aging derived from DNA methylation are promising biomarkers associated with prospective morbidity and mortality, but require validation in real-world medical settings. Using data from 2,216 post-9/11 veterans, we examined whether accelerated DunedinPACE aging scores were associated with chronic disease morbidity, predicted healthcare costs, and mortality assessed over an average of 13.1 years of follow up in VA electronic health records.

Black Americans With Sickle Cell Disease (SCD) Demonstrate Accelerated Epigenetic Pace of Aging Compared to Black Americans Without SCD.

Background: Sickle cell disease (SCD) is a chronic medical condition characterized by red blood cell sickling, vaso-occlusion, hemolytic anemia, and subsequently, end-organ damage and reduced survival. Because of this significant pathophysiology and early mortality, we hypothesized that patients with SCD are experiencing accelerated biological aging compared with individuals without SCD.

Methods: We utilized the DunedinPACE measure to compare the epigenetic pace of aging in 131 Black Americans with SCD to 1391 Black American veterans without SCD.

Native Mass Spectrometry Reveals Binding Interactions of SARS-CoV-2 PLpro with Inhibitors and Cellular Targets.

Here we used native mass spectrometry (native MS) to probe a SARS-CoV protease, PLpro, which plays critical roles in coronavirus disease by affecting viral protein production and antagonizing host antiviral responses. Ultraviolet photodissociation (UVPD) and variable temperature electrospray ionization (vT ESI) were used to localize binding sites of PLpro inhibitors and revealed the stabilizing effects of inhibitors on protein tertiary structure. We compared PLpro from SARS-CoV-1 and SARS-CoV-2 in terms of inhibitor and ISG15 interactions to discern possible differences in protease function.

Nurse-Supported Self-Directed Cognitive Behavioral Therapy for Insomnia: A Randomized Clinical Trial.

Importance: Cognitive behavioral therapy for insomnia (CBTi) is the standard of care for treating insomnia disorder, but access is limited. Alternative approaches are needed to expand access to the standard of care.

Objective: To examine the effectiveness of a nurse-supported, self-directed behavioral insomnia intervention for decreasing insomnia severity and improving sleep outcomes among veterans, a population with considerable mental health comorbidity.

Multimodal smoking cessation treatment combining repetitive transcranial magnetic stimulation, cognitive behavioral therapy, and nicotine replacement in veterans with posttraumatic stress disorder: A feasibility randomized controlled trial protocol.

Tobacco-related deaths remain the leading cause of preventable death in the United States. Veterans suffering from posttraumatic stress disorder (PTSD)-about 11% of those receiving care from the Department of Veterans Affairs (VA)-have triple the risk of developing tobacco use disorder (TUD). The most efficacious strategies being used at the VA for smoking cessation only result in a 23% abstinence rate, and veterans with PTSD only achieve a 4.

Behavioral activation for veterans with co-occurring alcohol use disorder and posttraumatic stress disorder: Basis and methodology for a pilot randomized controlled trial.

Background: Nearly 2 million U.S. veterans live with co-occurring alcohol use disorder and posttraumatic stress disorder (AUD/PTSD).

Brain Abscesses in the Tropics.

Purpose Of Review: This review aims to elucidate the etiologies of brain abscesses in the tropics. Despite the similarities in causes of brain abscesses across global regions, tropical settings manifest distinguishing characteristics, prominently observed on computed tomography or magnetic resonance imaging.

Recent Findings: In tropical climates, the leading conditions predisposing individuals to brain abscesses are polymicrobial bacterial infections originating from paranasal sinuses, dental sources, and otitis media.

Pathways Linking Post-Traumatic Stress Disorder to Incident Ischemic Heart Disease in Women: Call to Action.

Background: Post-traumatic stress disorder (PTSD) is associated with increased rates of incident ischemic heart disease (IHD) in women.

Objectives: The purpose of this study was to determine mechanisms of the PTSD-IHD association in women.

Methods: In this retrospective longitudinal cohort study, data were obtained from electronic health records of all U.

Electric Field Effects in Flash Joule Heating Synthesis.

Flash Joule heating has emerged as an ultrafast, scalable, and versatile synthesis method for nanomaterials, such as graphene. Here, we experimentally and theoretically deconvolute the contributions of thermal and electrical processes to the synthesis of graphene by flash Joule heating. While traditional methods of graphene synthesis involve purely chemical or thermal driving forces, our results show that the presence of charge and the resulting electric field in a graphene precursor catalyze the formation of graphene.

Deployment-related toxic exposures are associated with worsening mental and physical health after military service: Results from a self-report screening of veterans deployed after 9/11.

Exposure to toxins-such as heavy metals and air pollution-can result in poor health and wellbeing. Recent scientific and media attention has highlighted negative health outcomes associated with toxic exposures for U.S.

Demographic characteristics and epigenetic biological aging among post-9/11 veterans: Associations of DunedinPACE with sex, race, and age.

Measures of epigenetic aging derived from DNA methylation (DNAm) have enabled the assessment of biological aging in new populations and cohorts. In the present study, we used an epigenetic measure of aging, DunedinPACE, to examine rates of aging across demographic groups in a sample of 2,309 United States military veterans from the VISN 6 MIRECC's Post-Deployment Mental Health Study. As assessed by DunedinPACE, female veterans were aging faster than male veterans (β = 0.

Posttraumatic Stress Disorder Is Associated With Elevated Risk of Incident Stroke and Transient Ischemic Attack in Women Veterans.

Background: Posttraumatic stress disorder (PTSD) has been associated with ischemic heart disease in women veterans, but evidence for associations with other cardiovascular disorders remains limited in this population. This retrospective longitudinal cohort study evaluated the association of PTSD with incident stroke/transient ischemic attack (TIA) in women veterans.

Methods And Results: Veterans Health Administration electronic health records were used to identify women veterans aged ≥18 years engaged with Veterans Health Administration health care from January 1, 2000 to December 31, 2019.

Mental health treatment utilization among Gulf War era veterans with probable alcohol use disorder.

Introduction: Alcohol use disorder (AUD) is prevalent among veterans, and excessive alcohol use is associated with significant mental and physical health consequences. Currently, the largest cohort of veterans seeking services at the VA are those from the 1990s Gulf War Era. This cohort of veterans is unique due to the nature of their deployment resulting in a myriad of unexplained symptoms collectively known as "Gulf War Illness" and higher rates of mental health problems.

Nonlethal Molecular Nanomachines Potentiate Antibiotic Activity Against Gram-Negative Bacteria by Increasing Cell Permeability and Attenuating Efflux.

Antibiotic resistance is a pressing public health threat. Despite rising resistance, antibiotic development, especially for Gram-negative bacteria, has stagnated. As the traditional antibiotic research and development pipeline struggles to address this growing concern, alternative solutions become imperative.
