The Impact of Non-Pain Factors on Pain Interference Among U.S. Service Members and Veterans with Symptoms of Mild Traumatic Brain Injury.

U.S. Service members and Veterans (SM/V) experience elevated rates of traumatic brain injury (TBI), chronic pain, and other non-pain symptoms.

Advancements in biologic therapy in eosinophilic asthma.

Introduction: Asthma encompasses a spectrum of phenotypes often categorized into two groups- type 2 high (T2 high) and type 2 low (T2 low). T2 high includes atopic and eosinophilic presentations whereas T2 low is non-atopic, non-eosinophilic, and oft associated with neutrophilic inflammation. Eosinophilic asthma is often driven by IgE, IL-4, IL-5, and IL-13 and TSLP.

Characterizing Adrenergic Regulation of Glucose Transporter 4-Mediated Glucose Uptake and Metabolism in the Heart.

Whereas adrenergic stimulation promotes cardiac function that demands more fuel and energy, how this receptor controls cardiac glucose metabolism is not defined. This study shows that the cardiac β adrenoreceptor (βAR) is required to increase glucose transporter 4 (GLUT4)-mediated glucose uptake in myocytes and glucose oxidation in working hearts via activating the cardiac βAR and promotes the G inhibitory-phosphoinositide 3-kinase-protein kinase B cascade to increase phosphorylation of TBC1D4 (aka AS160), a Rab guanosine triphosphatase-activating protein, which is a key enzyme to mobilize GLUT4. Furthermore, deleting G-protein receptor kinase phosphorylation sites of βAR blocked adrenergic stimulation of GLUT4-mediated glucose uptake in myocytes and hearts.

Lichen planus esophagitis.

Purpose Of Review: Dysphagia is one of the most common reasons for patients' visits to a gastroenterologist. Esophageal lichen planus (ELP) has historically been felt to be a rare disease, when in fact it is often misdiagnosed and unrecognized. Often first diagnosed as an unusual esophagitis, all gastroenterologists will see ELP in their practice, and need to be able to recognize this condition.

Nasal allergen challenge (NAC): Practical aspects and applications from an EU/US perspective-a Work Group Report of the AAAAI Rhinitis, Rhinosinusitis and Ocular Allergy Committee.

Nasal allergen challenge (NAC) is applied in a variety of settings (research centers, specialty clinics, and hospitals) as a useful diagnostic and research tool. NAC is indicated for diagnosis of seasonal and perennial allergic rhinitis, local allergic rhinitis, and occupational rhinitis; to design the composition of allergen immunotherapy in patients who are polysensitized; and to investigate the physio-pathological mechanisms of nasal diseases. NAC is currently a safe and reproducible technique, although it is time- and resource-consuming.

The Joint Task Force on Practice Parameters GRADE guidelines for the medical management of chronic rhinosinusitis with nasal polyposis.

These evidence-based guidelines support patients, clinicians, and other stakeholders in decisions about the use of intranasal corticosteroids (INCS), biologics, and aspirin therapy after desensitization (ATAD) for the management of chronic rhinosinusitis with nasal polyposis (CRSwNP). It is important to note that the current evidence on surgery for CRSwNP was not assessed for this guideline nor were management options other than INCS, biologics, and ATAD. The Allergy-Immunology Joint Task Force on Practice Parameters formed a multidisciplinary guideline panel balanced to include the views of multiple stakeholders and to minimize potential biases.

Slow Burns: A Qualitative Study of Burn Pit and Toxic Exposures Among Military Veterans Serving in Afghanistan, Iraq and Throughout the Middle East.

During deployment to the Persian Gulf War and Southwest Asia theatre of operations, Veterans often experienced various hazards, foremost being open-air burn pits and oil well fires. While over 23 presumptive conditions (ranging from brain cancer, interstitial lung disease, and lymphomas to sleep/mood disorders, depression, and cognitive impairment) have been studied in connection with their military-related exposures, there is a paucity of qualitative research on this topic. This is especially true in the context of explanatory models and health belief systems, vis-à-vis underlying social and cultural factors.

Anaphylaxis: Access to Epinephrine in Outpatient Setting.

Epinephrine is a lifesaving medication to treat systemic allergic reactions including anaphylaxis. Epinephrine autoinjectors (EAIs) are expensive, not available everywhere in the world, and shortages can limit their access. Epinephrine prefilled syringes and epinephrine kits are lower-cost alternatives to EAIs.

STRONG STAR and the Consortium to Alleviate PTSD: Shaping the future of combat PTSD and related conditions in military and veteran populations.

The STRONG STAR Consortium (South Texas Research Organizational Network Guiding Studies on Trauma and Resilience) and the Consortium to Alleviate PTSD are interdisciplinary and multi-institutional research consortia focused on the detection, diagnosis, prevention, and treatment of combat-related posttraumatic stress disorder (PTSD) and comorbid conditions in military personnel and veterans. This manuscript outlines the consortia's state-of-the-science collaborative research model and how this can be used as a roadmap for future trauma-related research. STRONG STAR was initially funded for 5 years in 2008 by the U.

Myeloid Arginase 1 Insufficiency Exacerbates Amyloid-β Associated Neurodegenerative Pathways and Glial Signatures in a Mouse Model of Alzheimer's Disease: A Targeted Transcriptome Analysis.

Brain myeloid cells, include infiltrating macrophages and resident microglia, play an essential role in responding to and inducing neurodegenerative diseases, such as Alzheimer's disease (AD). Genome-wide association studies (GWAS) implicate many AD casual and risk genes enriched in brain myeloid cells. Coordinated arginine metabolism through arginase 1 () is critical for brain myeloid cells to perform biological functions, whereas dysregulated arginine metabolism disrupts them.

Arginase 1 Insufficiency Precipitates Amyloid- Deposition and Hastens Behavioral Impairment in a Mouse Model of Amyloidosis.

Alzheimer's disease (AD) includes several hallmarks comprised of amyloid- (Aβ) deposition, tau neuropathology, inflammation, and memory impairment. Brain metabolism becomes uncoupled due to aging and other AD risk factors, which ultimately lead to impaired protein clearance and aggregation. Increasing evidence indicates a role of arginine metabolism in AD, where arginases are key enzymes in neurons and glia capable of depleting arginine and producing ornithine and polyamines.

Immune Checkpoint Inhibitor-Induced Acute Pancreatitis and Colitis.

Given the promising response of immune checkpoint inhibitors (ICPIs) in treating advanced malignancies, their use in clinical practice is on the rise. ICPIs are associated with a wide spectrum of immune-related adverse events (irAEs). The reported side effects of therapy can be severe enough to require interruption or withdrawal.

Two forms of CX3CL1 display differential activity and rescue cognitive deficits in CX3CL1 knockout mice.

Background: Fractalkine (CX3CL1; FKN) is a chemokine expressed by neurons that mediates communication between neurons and microglia. By regulating microglial activity, CX3CL1 can mitigate the damaging effects of chronic microglial inflammation within the brain, a state that plays a major role in aging and neurodegeneration. CX3CL1 is present in two forms, a full-length membrane-bound form and a soluble cleaved form (sFKN), generated by a disintegrin and metalloproteinase (ADAM) 10 or 17.

Red Tide: Overview and Clinical Manifestations.

Harmful algal blooms occur when toxin-producing algae grow rapidly. These occur worldwide and have significant impacts on aquatic ecosystems and on human health. Specifically, the toxic blooms of Karenia brevis in Florida may affect humans via inhalation or ingestion.

Amputees' Attitudes Toward Participation in Amputee Support Groups and the Role of Virtual Technology in Supporting Amputees: Survey Study.

Background: Acquiring information about and living with an amputation (or limb differential) is a lifelong endeavor. Although medical institutions address the immediate medical needs of amputees, information regarding how to live life as an amputee is provided from numerous sources, one of which is amputee support groups.

Objective: This study aimed at understanding why amputees join support groups, leave support groups, and possibly return to support groups as well as how technology, specifically virtual reality, might play a role in supporting patients' needs.

Impact of Availability of Telehealth Programs on Documented HIV Viral Suppression: A Cluster-Randomized Program Evaluation in the Veterans Health Administration.

Background: Telehealth may improve care for people with HIV who live far from HIV specialty clinics. We conducted a cluster-randomized evaluation to determine the impact of availability of HIV telehealth programs on documented viral suppression in Veterans Administration clinics.

Methods: In 2015-2016, people who previously traveled to HIV specialty clinics were offered telehealth visits in nearby primary care clinics.

Factors Associated With Unplanned Reoperation After Above-Knee Amputation.

This study assesses factors associated with reoperation after above-knee amputations.

Effects of Exposure to New Car Interiors in Patients With Asthma and Allergic Rhinitis.

Rationale: Vehicle interiors are an important microenvironment for atopic subjects. This study evaluated the subjective and objective physiologic and clinical effects of exposing subjects with asthma and allergic rhinitis to new 2017 Mercedes vehicles during 90-minute rides.

Methods: Ten adult asthmatics with allergic rhinitis were assessed before and 45 and 90 minutes into rides in a 2017 Mercedes-Benz S-Class sedan and GLE-Class SUV on 2 separate days.

Economic considerations in the treatment of systemic allergic reactions.

Epinephrine is a life-saving medication used to treat systemic allergic reactions including anaphylaxis. Epinephrine autoinjectors (EAIs) are expensive and worldwide availability is limited. Epinephrine prefilled syringes and epinephrine kits are potentially lower-cost alternatives to EAIs.

Biological therapies for eosinophilic asthma.

Introduction: Severe uncontrolled asthma is by definition refractory to traditional therapies or can be controlled only with therapies that have intolerable side effects. Monoclonal antibodies that target interleukin (IL)-5/IL-5Rα, IgE, and IL-4Rα have shown favorable results in clinical trials, including reductions in asthma exacerbations and other important clinical outcomes. These biological agents offer treatment alternatives to patients with uncontrolled severe eosinophilic asthma.

Osteopontin plays a pivotal role in increasing severity of respiratory syncytial virus infection.

The molecular mechanisms underlying susceptibility to severe respiratory syncytial virus (RSV) infection remain poorly understood. Herein, we report on the role of osteopontin (OPN) in regulation of RSV infection in human epithelial cells and how interleukin-1 beta (IL-1β), a cytokine secreted soon after RSV infection, when persistently expressed can induce OPN expression leading to increased viral infection. We first compared OPN expression in two human epithelial cell lines: HEK-293 and HEp-2.
