Randomized Controlled Trial
Infant Feeding Practices, Workplace Breastfeeding/Lactation Practices, and Perception of Unit/Service Support Among Primiparous Active Duty Servicewomen.
Successful breastfeeding provides multiple health benefits to Servicewomen and their infants and has positive indirect benefits to the military. Workplace lactation support influences breastfeeding continuation after a Servicewoman's return to work. ⋯ While almost half of the respondents were still breastfeeding and planned to continue 5-6 months postpartum and the majority of respondents felt "mostly" or "very" supported in their breastfeeding by their unit and the Army, comprehensive physical support for lactation in the workplace was inconsistent. This study provides feedback to inform ongoing implementation of the existing Army breastfeeding support directive.

Temporal-spatial symmetry allows for optimal metabolic economy in unimpaired human gait. The gait of individuals with unilateral transfemoral amputation is characterized by temporal-spatial asymmetries and greater metabolic energy expenditure. The objective of this study was to determine whether temporal-spatial asymmetries account for greater metabolic energy expenditure in individuals with unilateral transfemoral amputation. ⋯ There is mixed evidence for the relationship between temporal-spatial asymmetries and metabolic energy expenditure. This preliminary study may suggest optimal metabolic energy expenditure in individuals with transfemoral amputation occurs at an individualized level of symmetry and resultant deviations incur a metabolic penalty. The results of this study support the idea that addressing only temporal-spatial gait asymmetries in individuals with transfemoral amputation through rehabilitation may not improve metabolic economy. Nevertheless, future prospective research is necessary to confirm these results and implications for clinical practice.

The rate of chronic migraine (CM) has been shown to be 20% or greater in the post 9/11 combat veteran population with a history of traumatic brain injury, while the rate is much lower at 3-5% in the general population. Studies have shown that medications such as oral topiramate or intramuscular injections of onabotulinum toxin A (Botox) have been used for CM prevention, and occipital blocks have been shown to be helpful in treating occipital neuralgia and short-term relief of CM. However, there are no known studies that have specifically evaluated the use of Botox and occipital blocks for reducing headache frequency in the US veteran population. The purpose of this study was to evaluate the effectiveness of using occipital blocks and Botox as dual therapy for reducing headache frequency in post 9/11 combat veterans with CM, occipital neuralgia, and a history of TBI or neck trauma. ⋯ This study evaluated the effectiveness of using occipital blocks and Botox as dual therapy for reducing headache frequency for post 9/11 combat veterans with CM, occipital neuralgia, and a history of TBI or neck trauma. Results revealed a statistically significant reduction in the number of headache days per month after the dual therapy. There were multiple limitations to the study to include a small sample size, lack of a control group, self-reported headaches for only 1 month pre-and post-treatment, and no control for other interventions or events which may have influenced the outcome. There is a strong need for randomized, double blinded, placebo- controlled studies involving dual therapy in this population. This study, though small, may be helpful in stimulating additional studies and treatments in this veteran population.

There is a widespread and long-held belief in the submarine community that submariners father more daughters than the general population. The U.S. Sex Ratio at birth (males/females) has remained around 1.05 since the early 2000s. Limited evidence exists that certain environmental exposures including chemicals, heavy metals, radiation and g-forces may influence sex ratio at birth. A reduction in male births in a population has been associated with lower male fertility. A 1970 single site study showed a higher ratio of female offspring in personnel serving aboard U.S. Navy nuclear submarines than the general population. A 2004 study concluded that this was probably not true. However, this study was small, and did not evaluate the difference between children conceived during sea duty versus shore duty. They did note a higher chance of female offspring correlated with a longer time in the community, as well as an increased ratio in sonar technicians. These findings warrant further investigation. ⋯ The submariners surveyed reported greater numbers of daughters than the general population, especially when on sea duty or in regular contact with submarines during shore duty. Further study should be done to confirm results and explore possible etiologies of differences in sex ratio.

Implementation and Evaluation of a Military-Civilian Partnership to Train Mental Health Specialists.
Mental health specialists (MHS, or 68X) play a central role in meeting the growing demand for combat stress care among Service Members. Partnering with civilian institutions may enhance the MHS training experience beyond Advanced Individual Training (AIT). ⋯ This is the first military-civilian training collaboration for behavioral health specialists, who have already completed AIT. This program provided well-received and mission-relevant training for MHS's without notable adverse effects on patient care or team functioning in a civilian environment. Our findings are based on a small sample size, and no other such programs exist against which to compare these results. We propose that such educational partnerships, which have long been effective for other clinical specialists, may benefit the military, civilian communities, and the country.
