Multitasking typically requires an individual to simultaneously process cognitive information while performing a motor task. Cognitive motor interference (CMi) is encountered when cognitive challenges negatively impact motor task performance. Military personnel encounter cognitively taxing situations, especially during combat or other tactical performance scenarios, which may lead to injury or motor performance deficits (i.e., shooting inaccuracy, delayed stimulus-response time, and slowed movement speed). The purpose of the current study was to develop four cognitive motor shooting paradigms to determine the effects of cognitive load on shooting performance in healthy Reserve Officers' Training Corps (ROTC) cadets. ⋯ The addition of a cognitive load increased both task initiation and task completion times during cognitive motor simulated shooting. Adding cognitive loads to tactical performance tasks can result in CMi and negatively impact tactical performance. Thus, consideration for additional cognitive challenges into training may be warranted to reduce the potential CMi effect on tactical performance.

Physical and medical readiness have emerged as a top priority in the army over the last decade. With this emphasis on deployment readiness, it is important to understand key risk factors attributed to common medical problems that arise in our soldiers, including low back pain. The purpose of this study is to elucidate demographic and lifestyle risk factors which would result in seeking medical care for musculoskeletal low back pain among active duty army personnel. ⋯ Disease burden for low back pain tends to be high in the U.S. Army with 34.7% of service members experiencing low back pain. Older age, obesity, and being an enlisted, female service member are risk factors for these musculoskeletal injuries, which is in agreement with previously reported literature on the topic. To mitigate the burden of low back pain, policies and incentives to encourage healthy body mass index and lifestyle are needed. The results of this work inform future studies aimed at further delineating the risk factors found in this study.

Psychiatric Conditions During Pregnancy and Postpartum in a Universally Insured American Population.
Mental health conditions are common and can have significant effects during the perinatal period. Our objective was to determine the incidences and predictors of psychiatric conditions during pregnancy and postpartum among universally insured American women. ⋯ In a universally insured population, the incidences of psychiatric conditions in pregnancy and within a year of delivery were similar to the American population. Additionally, the development of psychiatric conditions in pregnancy and within a year of delivery may be associated with race, active duty status, and complicated births.

Ultrasound-guided stellate ganglion block (SGB) is an injection of local anesthetic (8mL of 0.5% ropivacaine) in the neck to temporarily block the cervical sympathetic trunk which controls the body's fight-or-flight response. This outpatient procedure takes less than thirty minutes and is immediately effective. Our goal was to determine if a left-sided stellate ganglion block is effective for treating posttraumatic stress disorder (PTSD) symptoms. While right-sided SGB has been extensively studied, left-sided SGB has not been formally evaluated for this indication. ⋯ Based on our sample of 205 patients receiving SGB for PTSD, we concluded that at least 4.4% did not respond to a right-sided SGB but did have a significant response to a left-sided SGB.

The overall rate of obesity is rising in the USA; this is also reflected in the military population. It is important that providers appropriately diagnose obesity and discuss treatment options with their patients.The purpose of this study was to investigate diagnosis of obesity compared to documented body mass index (BMI) in the military health system. ⋯ This study demonstrates that obesity is underdiagnosed compared to BMI. This may result in insufficient resources being provided to patients to reduce weight. Further investigation is warranted to identify causes of underdiagnosis and potential barriers to diagnosis.
