Traumatic brain injury (TBI) remains a significant source of morbidity worldwide and is of particular concern for the military. Scientific literature examining sex differences in TBI is highly contradictory with some reporting better outcomes in men, others reporting better outcomes in women, and others reporting mixed results or no difference. While the exact cause is currently debated, the existence of such differences has important implications for surveillance techniques, treatment options, and management of long-term consequences. As the number of women within the U.S. military ranks increases and with the opening of combat roles to women in 2013, increased awareness of probable sex differences regarding TBI responses will enable better standard of care. ⋯ Emerging studies underscore the complexity of interpreting sex differences in TBI. The long-held belief that women have a neuroprotective advantage compared to men based on higher levels of sex hormones is being re-evaluated. Past conclusions have relied extensively on clinical studies that include a disproportionate number of men or do not stratify results based on sex. While sex hormones may be neuroprotective, underlying mechanisms are far from clarified. Future TBI studies must include women and gonadal hormone levels should be measured to address potential variables. Given the significant number of TBIs within the military, an improved understanding of TBI pathophysiology and outcomes is important considerations for mission success and servicemember longevity.

Randomized Controlled Trial
The Effect of Preoperative Behavioral Intervention on Pain, Anxiety, Opioid Use, and Function in Patients Undergoing Total Knee Arthroplasty: A Randomized Controlled Study.
To evaluate the efficacy of preoperative cognitive-behavioral psychoeducation (CBE) for improved pain, anxiety, opioid use, and postoperative function in total knee arthroplasty (TKA) patients. ⋯ A cognitive-behavioral approach to preoperative education may improve postoperative pain, anxiety, and function while decreasing opioid use among TKA patients. Findings from this pilot study support further research to examine similar interventions among distinct surgical populations and encourage further evaluation on the effects of CBE to enhance health and healthcare delivery.

As the number of U.S. veterans over age 65 has increased, interest in whether military service affects late-life health outcomes has grown. Whether military employment is associated with increased risk of cognitive decline and dementia remains unclear. ⋯ Among members of the Adult Changes in Thought cohort, military employment was not associated with increased risk of cognitive decline or dementia. Nevertheless, military veterans face the same high risks for cognitive decline and dementia as other aging adults.

To assess gaps in human papillomavirus (HPV) knowledge and current attitudes toward HPV vaccination among active duty soldiers at Fort Bragg, NC, and to evaluate the impact of the instruction intervention on knowledge and attitudes regarding HPV vaccination. ⋯ Results among soldiers demonstrated a lack of knowledge regarding HPV infection, its long-term effects, and preventive measures available among this population of active duty members. Assessment results also illustrated education about HPV infection and vaccination positively impacts soldiers' knowledge and attitudes toward HPV vaccination.

Recent epidemiological evidence shows that shoulder and upper-arm complaints impose a substantial burden on the armed forces of the United States and create significant challenges for all components of the physical fitness domain of total force fitness. Clinicians, epidemiologists, and health-services researchers interested in shoulder and upper-arm injuries and their functional limitations rarely have objective, validated criteria for rigorously evaluating diagnostic practices, prescribed treatments, or the outcomes of alternative approaches. We sought to establish and quantify patient volume, types of care, and costs within the Military Health System (MHS) in assessing and managing active duty members with nonoperative shoulder and upper-arm dysfunction. ⋯ Nearly 1 in 20 active duty military service members presented for nonoperative care of shoulder and/or upper-arm dysfunction during FY2014. Further examinations of the etiology and potential impact of shoulder/upper-arm dysfunction on force readiness are clearly warranted, as are additional studies directed at identifying best practices for preventing injury-related dysfunction and determining best practices for the treatment of shoulder dysfunction to optimize service member fitness and force readiness.
