Nutrition Interventions to Improve the Military Nutrition Environment Positively Impacts Service Members.

Introduction: This systematic review examines dietary interventions in the military nutrition environment (MNE) to support the health and performance of service members (SM).

Methods: Articles that implemented a dietary intervention for active duty SMs on military installations were included in this analysis (from 2010 to 2013). Of the 723 articles yielded in screening through Covidence, 6 studies qualified to be included in this review.

Time between pancreatic cancer diagnosis and treatment initiation and survival in the U.S. Military Health System.

Background: Pancreatic cancer has a high case fatality and treatment is known to improve survival. It is unknown whether the time between diagnosis and treatment initiation (time-to-treatment) is related to survival. Access to medical care may influence both treatment receipt and timing.

Advances in the Treatment of Congenital Infiltrating Lipomatosis of the Face: The Role of PIK3CA Mutations and Microvascular Reconstruction.

Congenital infiltrating lipomatosis of the face is a rare aggressive-benign disorder characterized by progressive hemifacial overgrowth and complex, often asymmetrical, facial differences. Recently linked with the PIK3CA-Related Overgrowth Spectrum, it arises from mosaic mutations in the PIK3CA gene. Treatment, largely supportive and tailored to individual clinical presentations, requires a multidisciplinary approach.

Risk for exertional heat illness among US army enlistees: climate indexes, intrinsic factors and their interactions.

Objectives: To characterise intrinsic and extrinsic (climatic) risks for mild and severe exertional heat illness (EHI) among first-year army enlistees.

Methods: We examined 337 786 soldiers who enlisted between 2012 and 2019. Survival models were used to predict incident EHI from intrinsic factors (demographics, healthcare utilisation, chronic conditions, body mass index (BMI), Army Physical Fitness Test (APFT), upper/lower respiratory tract infections (URTI and LRTI), skin and soft-tissue infections (SSTI), extrinsic factors (geographical region, daily mean Universal Thermal Climate Index (UTCI), wet bulb globe temperature (WBGT)) and interactions.

Heterozygous UBR5 variants result in a neurodevelopmental syndrome with developmental delay, autism, and intellectual disability.

E3 ubiquitin ligases have been linked to developmental diseases including autism, Angelman syndrome (UBE3A), and Johanson-Blizzard syndrome (JBS) (UBR1). Here, we report variants in the E3 ligase UBR5 in 29 individuals presenting with a neurodevelopmental syndrome that includes developmental delay, autism, intellectual disability, epilepsy, movement disorders, and/or genital anomalies. Their phenotype is distinct from JBS due to the absence of exocrine pancreatic insufficiency and the presence of autism, epilepsy, and, in some probands, a movement disorder.

Perceived barriers and facilitators to implementation of injury prevention programs in the military: Feedback from inside the trenches.

Background: Musculoskeletal injuries enact a substantial burden in military settings, incurring high costs, long-term disability, and impacting military readiness. This has led to a prioritization of injury prevention programs. Understanding the challenges faced by those trying to implement these programs could help standardize and better inform future efforts.

VezA/vezatin facilitates proper assembly of the dynactin complex in vivo.

Cytoplasmic dynein-mediated intracellular transport needs the multi-component dynactin complex for cargo binding and motor activation. However, the cellular factors involved in dynactin assembly remain unexplored. Here, we found in Aspergillus nidulans that the vezatin homolog VezA is important for dynactin assembly.

Comparing Black and White Patients in Treatment of Advanced Prostate Cancer and Survival in an Equal Access Health System.

Background: Racial disparities in prostate cancer treatment and survival in the U.S. have been attributed to differences in access to care and medical insurance.

Pharmacologically increasing cGMP improves proteostasis and reduces neuropathy in mouse models of CMT1.

Increasing cyclic GMP activates 26S proteasomes via phosphorylation by Protein Kinase G and stimulates the intracellular degradation of misfolded proteins. Therefore, agents that raise cGMP may be useful therapeutics against neurodegenerative diseases and other diseases in which protein degradation is reduced and misfolded proteins accumulate, including Charcot Marie Tooth 1A and 1B peripheral neuropathies, for which there are no treatments. Here we increased cGMP in the S63del mouse model of CMT1B by treating for three weeks with either the phosphodiesterase 5 inhibitor tadalafil, or the brain-penetrant soluble guanylyl cyclase stimulator CYR119.

Systemic inflammation following traumatic injury and its impact on neuroinflammatory gene expression in the rodent brain.

Background: Trauma can result in systemic inflammation that leads to organ dysfunction, but the impact on the brain, particularly following extracranial insults, has been largely overlooked.

Methods: Building upon our prior findings, we aimed to understand the impact of systemic inflammation on neuroinflammatory gene transcripts in eight brain regions in rats exposed to (1) blast overpressure exposure [BOP], (2) cutaneous thermal injury [BU], (3) complex extremity injury, 3 hours (h) of tourniquet-induced ischemia, and hind limb amputation [CEI+tI+HLA], (4) BOP+BU or (5) BOP+CEI and delayed HLA [BOP+CEI+dHLA] at 6, 24, and 168 h post-injury (hpi).

Results: Globally, the number and magnitude of differentially expressed genes (DEGs) correlated with injury severity, systemic inflammation markers, and end-organ damage, driven by several chemokines/cytokines (Csf3, Cxcr2, Il16, and Tgfb2), neurosteroids/prostaglandins (Cyp19a1, Ptger2, and Ptger3), and markers of neurodegeneration (Gfap, Grin2b, and Homer1).

Alterations in GABA receptor-mediated inhibition triggered by status epilepticus and their role in epileptogenesis and increased anxiety.

The triggers of status epilepticus (SE) in non-epileptic patients can vary widely, from idiopathic causes to exposure to chemoconvulsants. Regardless of its etiology, prolonged SE can cause significant brain damage, commonly resulting in the development of epilepsy, which is often accompanied by increased anxiety. GABA receptor (GABAR)-mediated inhibition has a central role among the mechanisms underlying brain damage and the ensuing epilepsy and anxiety.

Racial-Ethnic Comparison of Treatment for Papillary Thyroid Cancer in the Military Health System.

Purpose: We aimed to compare Asian or Pacific Islander, Black, Hispanic, and non-Hispanic White patients in treatment for papillary thyroid cancer (PTC) in the equal access Military Health System to better understand racial-ethnic cancer health disparities observed in the United States.

Methods: We used the MilCanEpi database to identify a cohort of men and women aged 18 or older who were diagnosed with PTC between 1998 and 2014. Low- or high-risk status was assigned using tumor size and lymph node involvement.

Bilateral renal agenesis: fetal intervention and outcomes.

Bilateral renal agenesis (BRA) is a fetal anomaly which leads to anhydramnios and resultant pulmonary hypoplasia. Historically, this anomaly was universally fatal early in the neonatal period due to the severity of the associated lung disease. Over the last 30 years, innovations in fetal therapies-specifically, serial amnioinfusions-have led to instances of infant pulmonary survival and initiation of postnatal dialysis, raising the possibility that early neonatal death may not be inevitable.

Proteomic analysis of plasma at the preterminal stage of rhesus nonhuman primates exposed to a lethal total-body dose of gamma-radiation.

The identification and validation of radiation biomarkers is critical for assessing the radiation dose received in exposed individuals and for developing radiation medical countermeasures that can be used to treat acute radiation syndrome (ARS). Additionally, a fundamental understanding of the effects of radiation injury could further aid in the identification and development of therapeutic targets for mitigating radiation damage. In this study, blood samples were collected from fourteen male nonhuman primates (NHPs) that were exposed to 7.

Pathology of acute sub-lethal or near-lethal irradiation of nonhuman primates prophylaxed with the nutraceutical, gamma tocotrienol.

Exposure to high, marginally lethal doses or higher of ionizing radiation, either intentional or accidental, results in injury to various organs. Currently, there is only a limited number of safe and effective radiation countermeasures approved by US Food and Drug Administration for such injuries. These approved agents are effective for only the hematopoietic component of the acute radiation syndrome and must be administered only after the exposure event: currently, there is no FDA-approved agent that can be used prophylactically.

Low-dose radiation decreases Lrrk2 levels in the striatum of large mammalian brains: New venues to treat Parkinson's disease?

Introduction: Among gene mutations and variants linked to an increased risk of PD, mutations of leucine-rich repeat kinase 2 gene (LRRK2) are among the most frequently associated with early- and late-onset PD. Clinical and neuropathological characteristics of idiopathic-PD (iPD) and LRRK2-PD are similar, and these similarities suggest that the pathomechanisms between these two conditions are shared. LRRK2 mutations determine a gain-of-function and yield higher levels of lrrk2 across body tissues, including brain.

Definition, diagnosis and classification of infection-related movement disorders: Consensus proposal.

Background: Infection-related movement disorders (IRMD) present a complex diagnostic challenge due to the broad phenotypic spectrum, the variety of possible infectious aetiologies, and the complicated underlying mechanisms. Yet, a comprehensive framework for classifying IRMD is lacking.

Methods: An international consensus panel under the directives of the Movement Disorders Society Infection-Related Movement Disorders Study Group developed a comprehensive definition and a consensus classification system.

Histopathological studies of nonhuman primates exposed to supralethal doses of total- or partial-body radiation: influence of a medical countermeasure, gamma-tocotrienol.

Despite remarkable scientific progress over the past six decades within the medical arts and in radiobiology in general, limited radiation medical countermeasures (MCMs) have been approved by the United States Food and Drug Administration for the acute radiation syndrome (ARS). Additional effort is needed to develop large animal models for improving the prediction of clinical safety and effectiveness of MCMs for acute and delayed effects of radiation in humans. Nonhuman primates (NHPs) are considered the animal models that reproduce the most appropriate representation of human disease and are considered the gold standard for drug development and regulatory approval.

Serum microRNA profile of rhesus macaques following ionizing radiation exposure and treatment with a medical countermeasure, Ex-Rad.

Exposure to ionizing radiation (IR) presents a formidable clinical challenge. Total-body or significant partial-body exposure at a high dose and dose rate leads to acute radiation syndrome (ARS), the complex pathologic effects that arise following IR exposure over a short period of time. Early and accurate diagnosis of ARS is critical for assessing the exposure dose and determining the proper treatment.

Treatment of pancreatic adenocarcinoma in relation to survival in the U.S. Military Health System.

Background: Pancreatic cancer has a high case fatality and relatively short survival after diagnosis. Treatment is paramount to improving survival, but studies on the effects of standard treatment by surgery or chemotherapy on survival in U.S.

The potential value of 5-androstenediol in countering acute radiation syndrome.

Moderate-to-high doses of ionizing irradiation can lead to potentially life-threatening morbidities and increase mortality risk. In preclinical testing, 5-androstenediol has been shown to be effective in protecting against hematopoietic acute radiation syndrome. This agent is important for innate immunity, serves to modulate cell cycle progression, reduces radiation-induced apoptosis, and regulates DNA repair.
