Military personnel and their families face biopsychosocial risk factors due to frequent deployments, long and dangerous assignments, being away from home, not being able to spend time with their family, and adaptation to family life after returning from duty. These risks are among the factors affecting the marital satisfaction of military families. ⋯ This study reveals that long-term and far-from-home assignments due to military service impact the marital satisfaction. Accordingly, it was observed that military spouses and families must be supported during the soldiers' duties and complicated professional processes.

Randomized Controlled Trial
Determining Intraosseous Needle Placement Using Point-of-Care Ultrasound in a Swine (Sus scrofa) Model.
Intraosseous (IO) access is critical in resuscitation, providing rapid access when peripheral vascular attempts fail. Unfortunately, misplacement commonly occurs, leading to possible fluid extravasation and tissue necrosis. Current research exploring the utility of bedside ultrasound in confirming IO line placement is limited by small sample sizes of skeletally immature subjects or geriatric cadaveric models. The objective of this study was to investigate the potential value of ultrasound confirming IO needle placement in a live tissue model with bone densities approximated to the young adult medical or trauma patient. ⋯ Within the context of this study, point-of-care ultrasound with CPD did not reliably confirm IO line placement. However, more accurate assessments of functional and malpositioned catheters were noted in sonographers with greater than 4 years of experience. Future study into experienced sonographers' use of CPD to confirm IO catheter placement is needed.

The Korean War (1950-1953) consisted of two phases. The first was a rapid mobile phase, and the second was a slow and stationary phase. During the stationary phase, approximately 3,000 UN troops became infected with a then unknown agent. The resulting illness began with flu-like symptoms and often progressed to a severe hemorrhagic fever leading to kidney failure and death. However, the cause was not to be identified until well over 20 years following the conclusion of the war when Dr. Ho Wang Lee succeeded in isolating Hantavirus from field rodents. The U.S. Military experience with Hantavirus during the Korean War is a case study of the potential impact of war-related environmental change on disease transmission. The lessons learned from this experience should inform future military medical planning and serve as a reminder of the impact that an unknown agent can have on military operations. ⋯ A basic understanding of the ecological mechanisms that maintain species diversity in the local environment coupled with an appreciation for the impact of environmental change on this diversity is of paramount importance for the prevention and mitigation of viral disease outbreaks in the deployed setting. Military medical planners should become familiar with the medical literature of the region in which they will be operating as this literature often describes the agents that will most likely be encountered by U.S. forces.

Validity of the Modified Defense and Veterans Pain Rating Scale Supplemented With Items Germane to Total Joint Replacement: Secondary Analysis From a Randomized Trial.
Valid measures of pain are helpful to adjust treatment plans in real time after total joint replacement (TJR). We enhanced the existing Defense and Veterans Pain Rating Scale (DVPRS) with items related to pain at rest and movement, in specific reference to operative and nonoperative joints, creating the TJR-DVPRS. This manuscript is presented to validate the modified survey instrument. The aims of this psychometric study were to evaluate (1) the latent structure of the TJR-DVPRS, (2) the relationships among the pain dimensions represented on the TJR-DVPRS and the reference-standard Short-Form McGill Pain Questionnaire (version 2, SF-MPQ-2), and (3) the responsiveness of these two measures before and after TJR. ⋯ The TJR-DVPRS is valid for use among veterans undergoing TJR and poses significantly less respondent burden than does the SF-MPQ-2. The brevity and ease of use of the TJR-DVPRS make it a practical tool for use during surgical recovery to monitor pain intensity at rest and with movement in the operative joint, and to assess pain interference with activity, sleep, and mood. The TJR-DVPRS is at least as responsive as the SF-MPQ-2, but the SF-MPQ-2 neuropathic and TJR-DVPRS nonoperative joint subscales were minimally responsive. Limitations of this study include the small sample size, under-representation of women (which would be expected in the veteran population), and using only veterans. Future validations studies should include civilians and active military TJR patients.
