Back Pain in Outer Space.

Space travel has grown during the past 2 decades, and is expected to surge in the future with the establishment of an American Space Force, businesses specializing in commercial space travel, and National Aeronautics and Space Administration's planned sustained presence on the moon. Accompanying this rise, treating physicians are bracing for a concomitant increase in space-related medical problems, including back pain. Back pain is highly prevalent in astronauts and space travelers, with most cases being transient and self-limiting (space adaptation back pain). Pathophysiologic changes that affect the spine occur during space travel and may be attributed to microgravity, rapid acceleration and deceleration, and increased radiation. These include a loss of spinal curvature, spinal muscle atrophy, a higher rate of disc herniation, decreased proteoglycan and collagen content in intervertebral discs, and a reduction in bone density that may predispose people to vertebral endplate fractures. In this article, the authors discuss epidemiology, pathophysiology, prevention, treatment, and future research.

Screening for Complicated Grief in a Military Mental Health Clinic.

INTRODUCTION: Bereavement is one of the most common and stressful life experiences one can endure. Typical grief reactions follow a course of recovery in which individuals come to terms with the loss and resume functioning within weeks to months. However, for some, grief remains indefinitely distressing. Complicated Grief (CG) refers to significant chronic impairment that stems from bereavement. Military service members experience myriad factors that likely increase their risk for developing CG. Such factors include unique bonds between service members, exposure to constant and extreme levels of stress, multiple losses, separation from family and loved ones, witnessing/learning about sudden violent and traumatic deaths, and handling human remains. The aim of this project was to explore the practicality and efficiency of screening for CG within a busy military mental health clinic, and also explore relationships between contextual variables related to a death that might be associated with screening positive for CG. MATERIALS AND METHODS: As part of a clinical needs assessment, patients from a single mental health clinic at Naval Medical Center San Diego completed a brief grief survey that asked if they experienced a death of a person close to them, collected metrics related to losses they have experienced and included validated screeners for CG (The Brief Grief Questionnaire [BGQ] and the Inventory for Complicated Grief [ICG]). No data concerning gender, age, marital status, socioeconomic status, diagnosis, or purpose of visit (i.e., initial or follow-up visit) were collected. Institutional review board approval was obtained. RESULTS: In our sample of service members presenting to an adult outpatient military mental health clinic, 43.5% reported having experienced a loss that still impacts them. Of that group, 61.7% screened positive on the BGQ, 59.2% screened positive on the ICG using a cutoff of 25, and 46.1% screened positive on the ICG using the cutoff of 30. These findings suggest that military service members seeking mental health treatment who endorsed experiencing a loss are at high risk for experiencing persisting, impairing grief. Additionally, patients who either lost a fellow service member and/or experienced loss while on deployment reported significantly higher scores on the BGQ or ICG than if they did not report those factors. Furthermore, correlations between total number of losses and ICG scores suggest that service members who experienced multiple losses may be more susceptible to CG symptoms. CONCLUSION: The findings from this preliminary investigation suggest that many service members receiving care in military mental health care are experiencing grief-related symptoms and distress, and a brief screen for grief can help capture many of those with grief related impairment. Research shows that CG needs to be directly targeted to treat its symptoms and associated impairment. We recommend that military mental health clinics consider adding some type of grief screener to their standard intake as well as making providers aware of the importance of monitoring potential grief reactions in their patients.
