Mild Traumatic Brain Injury and Career Stage Associate with Visible Perivascular Spaces in Special Operations Forces Soldiers.

Mild traumatic brain injury (mTBI) and occupational blast exposure in military Service Members may lead to impaired brain waste clearance which increases neurological disease risk. Perivascular spaces (PVS) are a key part of the glymphatic system which supports brain waste clearance, preferentially during sleep. Visible PVS on clinical magnetic resonance imaging have been previously observed in patients with neurodegenerative diseases and animal neurotrauma models.

Nontraumatic Subarachnoid Hemorrhage and Ruptured Intracranial Aneurysm: Recognition and Evaluation.

Subarachnoid hemorrhage caused by a ruptured intracranial aneurysm is a neurosurgical emergency with a mortality rate of approximately 50%. Prompt identification and treatment of aneurysmal subarachnoid hemorrhage are paramount to reduce mortality, long-term morbidity, and health care burden for survivors. The prevalence of intracranial aneurysms is 2% to 6% of the global population, many of which are found incidentally during workup for an unrelated condition.

Defining Speaking Up in the Healthcare System: a Systematic Review.

Background: Communication issues have been shown to contribute to healthcare errors. For years healthcare professionals have been told to "speak up." What "speak up" means is unclear, as it has been defined and operationalized in many ways.

Mild traumatic brain injury history is associated with lower brain network resilience in soldiers.

Special Operations Forces combat soldiers sustain frequent blast and blunt neurotrauma, most often classified as mild traumatic brain injuries. Exposure to repetitive mild traumatic brain injuries is associated with persistent behavioural, cognitive, emotional and neurological symptoms later in life. Identifying neurophysiological changes associated with mild traumatic brain injury exposure, in the absence of present-day symptoms, is necessary for detecting future neurological risk.

Athletes With Attention-Deficit/Hyperactivity Disorder: Position Statement of the American Medical Society for Sports Medicine.

Athletes of all ages may be affected by medical and mental health issues. Sports medicine physicians should be familiar with common conditions that may affect the well-being of athletes, such as attention-deficit/hyperactivity disorder (ADHD). ADHD behaviors have the potential to affect a person's ability to concentrate.

Active Warfighter Mental Health Lower in Mid-Career.

Purpose: The present study investigated Special Operations Forces (SOF) combat Servicemember mental health at different SOF career stages in association with resilience.

Methods: Fifty-eight SOF combat Service Members either entering SOF (career start; n=38) or multiple years with their SOF organization (mid-career; n=20) self-reported mild traumatic brain injury (TBI) history, resilience, subjective well-being, depression, anxiety, and posttraumatic stress. Poisson regression analyses were employed to test SOF career stage differences in each mental health symptom using resilience, while accounting for other pertinent military factors.

Warfighter Resilience.

Purpose: Our aim in this study was to psychometrically test resilience assessments (Ego Resiliency Scale [ER89], Connor-Davidson Resilience Scale [CD-RISC 25], Responses to Stressful Experiences Scale [RSES short-form]) and describe resilience levels in a Special Operations Forces (SOF) combat sample.

Methods: Fifty-eight SOF combat Servicemembers either entering SOF (career start; n = 38) or having served multiple years with their SOF organization (mid-career; n = 20) self-reported resilience, mild traumatic brain injury (mTBI) history, and total military service.

Results: All resilience metrics demonstrated acceptable internal consistency, but ceiling effects were found for CD-RISC and RSES scores.

Relationship between Anterior Pituitary Volume and IGF-1 Serum Levels in Soldiers with Mild Traumatic Brain Injury History.

Purpose: A high mild traumatic brain injury (mTBI) incidence rate exists in military and sport. Hypopituitarism is an mTBI sequela; however, few studies have examined this phenomenon in those with an mTBI history. This cross-sectional study of Special Operations Forces combat soldiers aimed 1) to relate anterior pituitary gland volumes (actual and normalized) to insulin-like growth factor 1 (IGF-1) concentrations, 2) to examine the effect of mTBI history on anterior pituitary gland volumes (actual and normalized) and IGF-1 concentrations, and 3) to measure the odds of demonstrating lower anterior pituitary gland volumes (actual and normalized) or IGF-1 concentrations if self-reporting mTBI history.

Hereditary Hemochromatosis: Rapid Evidence Review.

Hereditary hemochromatosis is an autosomal recessive disorder that disrupts iron homeostasis, resulting in systemic iron overload. It is the most common inherited disorder among people of northern European ancestry. Despite the high prevalence of the gene mutation, there is a low and variable clinical penetrance.

Heart Failure: Heart Failure With Preserved Ejection Fraction.

The incidence and prevalence of heart failure (HF) in the United States are high, with an estimated 6.2 million cases, and these numbers are expected to increase. Age is a nonmodifiable risk factor for HF development.

The relationship between resilience and neurophysiological stress in Special Operations Forces combat service members.

Military resilience research is increasing due to the growing literature associating resilience with stress adaptation. This study aimed to investigate which physiological stress adaptation components were associated with resilience in Special Operations Forces combat service members. Special Operations Forces combat service members (n = 117) self-reported resilience (ER89) and lifetime clinician-confirmed mild traumatic brain injury history.

Degenerative Cervical Myelopathy: Recognition and Management.

Degenerative cervical myelopathy encompasses a collection of pathologic conditions that result in progressive spinal cord dysfunction secondary to cord compression. Patients are typically male (3: 1 male-to-female ratio), and the average age of presentation is 64 years. The exact incidence is unclear because of differences in terminology and because radiographic findings can be present in asymptomatic individuals.

Neurovascular Coupling in Special Operations Forces Combat Soldiers.

The purpose of this study was to investigate how concussion history affects neurovascular coupling in Special Operations Forces (SOF) combat Soldiers. We studied 100 SOF combat Soldiers [age = 33.5 ± 4.

Neuroinflammatory Biomarkers Associated With Mild Traumatic Brain Injury History in Special Operations Forces Combat Soldiers.

Background: Special Operations Forces (SOF) combat soldiers are frequently exposed to blast and blunt neurotrauma, most often classified as mild traumatic brain injury (mTBI). Repetitive mTBI may increase the risk of developing long-term neurological sequelae. Identifying changes in neuroinflammatory biomarkers before chronic conditions emerge could serve as preliminary evidence of developing neuropathology.

Mental Health Symptoms Are Associated With Mild Traumatic Brain Injury History in Active Special Operations Forces (SOF) Combat and Combat Support Soldiers.

Introduction: Special Operations Forces (SOF) combat arms and combat support Soldiers are at risk for impaired mental health, such as mood- and stress-related disorders, due to operational and training demands. Additionally, these individuals experience high risk for sustaining mild traumatic brain injury (mTBI). These mTBIs have also been linked to negative psychological outcomes, such as anxiety and depressive symptoms.

The relationship between neurovascular coupling, vision and sensory performance, and concussion history in Special Operations Forces combat soldiers.

Objective: To determine the relationship between neurovascular coupling (NVC), vision and sensory performance in Special Operations Forces (SOF) combat soldiers with and without concussion history.

Methods: We studied 61 SOF combat soldiers (male, age = 33.8 ± 3.

Bone Tumors: Multiple Myeloma.

Multiple myeloma (MM) is a malignancy of bone marrow plasma cells that produce abnormal immunoglobulins. It is the second most common hematologic cancer and typically is diagnosed in individuals ages 65 to 74 years. MM is the final stage in a continuum that starts with monoclonal gammopathies of undetermined significance (MGUS), a premalignant condition characterized by production of abnormal immunoglobulins.

Cerebrovascular Reactivity in Special Operations Forces Combat Soldiers.

The purpose of this study was to investigate how concussion history affects cerebrovascular reactivity (CVR) in Special Operations Forces (SOF) combat soldiers. We studied 104 SOF soldiers [age = 33.5 ± 4.

Augmented Reality Forward Damage Control Procedures for Nonsurgeons: A Feasibility Demonstration.

Introduction: This article presents an emerging capability to project damage control procedures far forward for situations where evacuation to a formal surgical team is delayed. Specifically, we demonstrate the plausibility of using a wearable augmented reality (AR) telestration device to guide a nonsurgeon through a damage control procedure.

Methods: A stand-alone, low-profile, commercial-off-the-shelf wearable AR display was utilized by a remotely located surgeon to synchronously guide a nonsurgeon through proximal control of the distal external iliac artery on a surgical manikin.

Hand-Foot-and-Mouth Disease: Rapid Evidence Review.

Hand-foot-and-mouth disease is caused by human enteroviruses and coxsackieviruses. Outbreaks can occur in the spring to fall and are common in North America, and most cases occur in patients younger than 10 years. Hand-foot-and-mouth disease is transmitted by fecal-oral, oral-oral, and respiratory droplet contact.

Management of Chronic Tendon Injuries.

Chronic tendon injuries are common athletic and occupational injuries that account for many physician visits. Tendons have a complex biology that provides a unique combination of strength, flexibility, and elasticity but also predisposes them to injury. The term tendinopathy is preferred to tendinitis because of the presence of a disordered and degenerative healing process-not inflammation-in the pathologic tendon.

American Medical Society for Sports Medicine position statement on concussion in sport.

Sport-related concussion (SRC) is a common injury in recreational and organised sport. Over the past 30 years, there has been significant progress in our scientific understanding of SRC, which in turn has driven the development of clinical guidelines for diagnosis, assessment and management of SRC. In addition to a growing need for knowledgeable healthcare professionals to provide evidence-based care for athletes with SRC, media attention and legislation have created awareness and, in some cases, fear about many issues and unknowns surrounding SRC.
