The survival rate of those injured in combat in overseas contingency operations is higher than in previous conflicts. There is a need to assess the long-term psychosocial and quality of life outcomes of those injured in combat, yet surveying this population presents inherent challenges. As part of a large-scale, longitudinal examination of patient-reported outcomes of service members injured on deployment, the present manuscript evaluated the effectiveness of three postal strategies on response rates: (1) mailing a study prenotification postcard, (2) mailing the survey invitation in a larger envelope, and (3) including a small cash preincentive ($2).

Background: Mammalian target of rapamycin (mTOR) inhibitors are approved to prevent allograft rejection and control malignancy. Unfortunately, they are associated with adverse effects, such as wound healing complications that detract from more extensive use. There is a lack of prospective wound healing studies to monitor patients treated with mTOR inhibitors, such as everolimus or sirolimus, especially in nondiabetics.

Obese patients are susceptible to increased morbidity and mortality associated with infectious diseases such as influenza A virus. γδ T cells and memory αβ T cells play key roles in reducing viral load by rapidly producing IFN-γ and lysing infected cells. In this article we analyze the impact of obesity on T lymphocyte antiviral immunity.

Blast-related ear injuries are a concern during deployment because they can compromise a servicemember's situational awareness and adversely affect operational readiness. The objectives of this study were to describe blast-related ear injuries during Operation Iraqi Freedom, identify the effect of hearing protection worn at the point of injury, and explore hearing loss and tinnitus outcomes within one year after injury. The Expeditionary Medical Encounter Database was used to identify military personnel who survived blast-related injury, and it was linked with outpatient medical databases to obtain diagnoses of hearing loss and tinnitus.

Objective: We investigated the association of the length of time spent at home between deployments, or dwell time, with posttraumatic stress disorder (PTSD) and other mental health disorders.

Methods: We included US Marine Corps personnel identified from military deployment records who deployed to Operation Iraqi Freedom once (n = 49,328) or twice (n = 16,376). New-onset mental health diagnoses from military medical databases were included.

Introduction: Cigarette smoking has been reported to be higher among deployed military men than among similarly aged civilian or nondeployed men, but the short-term effect of smoking on physical fitness among these young healthy men is unclear. This study examined self-reported smoking status and change in objectively measured fitness over 1-4 years while controlling for body mass index (BMI).

Methods: This study included a large sample of male U.
