Transcranial electrical stimulation (tES) as a method of cognitive enhancement in both diseased and healthy individuals has gained popularity. Its potential for enhancing cognition in healthy individuals has gained the interest of the military. However, before it being implemented into military training or operational settings, further work is needed to determine its efficacy and safety. Although a considerable amount of literature exists, few studies have specifically evaluated its use in enhancing cognition relative to operational, military tasks. Therefore, in a first step to evaluate its efficacy, we completed a systematic literature review of studies using transcranial direct current stimulation (tDCS), a type of tES, to enhance cognitive processes in healthy individuals. ⋯ The conclusions to be drawn from this systematic literature review include the identification of a brain region for targeting with stimulation to enhance a broad range of cognitive constructs applicable to military tasks, as well as stimulation parameters for duration and intensity. The dorsolateral prefrontal cortex was most frequently targeted in the studies that found enhanced performance across several cognitive constructs. Stimulation intensities of 2 mA and durations of 20 minutes or longer appeared frequently as well. Although several parameters were identified, further work is required before this type of technology can be recommended for operational use.

Observational Study
Safety Events and Privilege Utilization Rates in Advanced Practice Physical Therapy Compared to Traditional Primary Care: An Observational Study.
The general practitioner shortage in the United States coupled with a growing number of Americans living with disability has fueled speculation of non-physician providers assuming a greater role in musculoskeletal healthcare. Previous physician shortages have been similarly addressed, and expanding physical therapy (PT) scope of practice may best serve to fill this need. Resistance to expanding PT practice focuses on patient safety as PTs assume the roles traditionally performed by primary care providers. While studies have shown advanced practice PT to be safe, none have compared safety events in advanced practice PT compared to primary care to determine if there are increased patient risks. Therefore, the purpose of our study is to examine the rate of safety events and utilization of services in an advanced practice PT clinic compared to a primary care clinic. A secondary aim of our study was to report safety events associated with spinal manipulation and dry needling procedures. ⋯ These results suggest advanced practice PT has a similar safety profile to primary care. The authority to order musculoskeletal imaging and refer to other clinicians were among the most commonly utilized privileges and may be of primary importance when establishing an advanced practice PT clinic. These results support research showing advanced practice PT may lead to reductions in specialty referrals, diagnostic imaging, and pharmaceutical interventions.

Given the role of perceived stress in disability and suicidality in the military, intervening early before service members become at risk for severe injuries, hospitalizations, and chronic disability could improve health outcomes. The purpose of this study was to explore the feasibility and acceptability of a standardized stress acupuncture (SSA) approach on perceived stress in U.S. military personnel. This study had the following aims: examine feasibility of recruitment for SSA and implementation of study procedures in preparation for a methodologically rigorous study; examine acceptability of SSA treatment in a sample of military personnel with perceived stress; and examine change in perceived stress and general health before and after SSA. ⋯ These results suggest that SSA is a feasible and acceptable treatment for perceived stress in military personnel. Preliminary findings suggest that SSA may be useful in improving energy/fatigue, social functioning, and perceived stress of service members.

Multicenter Study
Influence of Time to Transport to a Higher Level Facility on the Clinical Outcomes of US Combat Casualties with TBI: A Multicenter 7-Year Study.
Traumatic brain injury (TBI) is a leading cause of death and disability worldwide and is associated with mortality rates as high as 30%. Patients with TBI are at high risk for secondary injury and need to be transported to definitive care expeditiously. However, the physiologic effects of aeromedical evacuation are not well understood and may compound these risks. Combat TBI patients may benefit from delayed aeromedical evacuation. The goal of this study was to evaluate the impact of transport timing out of theater via Critical Care Air Transport Teams (CCATT) to a higher level facility on the clinical outcomes of combat casualties with TBI. ⋯ In patients with moderate to severe TBI, a delay in aeromedical evacuation out of the combat theater was associated with improved mortality rates and a higher likelihood of discharge to home and return to duty dispositions. This study is correlational in nature and focused on CCATT transports from Role III to Role IV facilities; as such, care must be taken in interpreting our findings and future studies are needed to establish a causal link between delayed evacuation and improved discharge disposition. Our study suggests that delaying aeromedical evacuation of TBI patients when feasible may confer benefit.
