Randomized Controlled Trial
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.

Shiitake flagellate dermatitis is an intensely pruritic erythematous or violaceous eruption marked by "whip-like" linear streaks consisting of papules or plaques following the ingestion of undercooked shiitake mushrooms (Lentinula edodes). Most commonly localized on the trunk and upper limbs, the characteristic pattern of the rash is associated with the consumption of lentinan, a thermolabile toxin found within the mushroom, as well as a broad range of other dermatological conditions, including dermatomyositis, adult-onset Still's disease, and reactions to medications such as bleomycin. ⋯ As U. S. forces pivot to operating in austere and resource-limited settings in the Pacific, recognizing the spectrum of diagnoses encompassed by flagellate erythema is important for maintaining operational readiness and differentiating self-limited cutaneous manifestations from more serious underlying conditions associated with this finding.

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.

Military families face many unique challenges, including frequent separations, demanding work hours, and relocations. The HealthySteps (HS) program may offset these challenges utilizing the expertise of a nonclinical child development specialist called a HS specialist who offers enhanced well-child visits (WCVs), support between visits, and connections to community resources. Our study sought to identify the impact of the military HS pilot program on the timeliness of WCVs, immunizations, routine behavioral and developmental screenings, and referrals to community resources within the first 15 months of life (MOL). ⋯ The results of this study indicate the positive impacts of the military HS program on referrals to community resources and PPD screening, reflecting the HS specialist focus on the family unit. Limitations of this study include the small population size and limited demographic information resulting from the retrospective nature of the study and pilot status of the HS program. Larger prospective studies are needed to clarify the true impact of the HS program in the military health system.

Randomized Controlled Trial
Diver Underwater Cycling Endurance After Short-Term Warm and Hot Water Acclimation.
It is unclear whether immersion heat acclimation benefits exercise in warm water conditions. This study examined the effects of heat acclimation strategies on heart rate (HR), core temperature, and time to exhaustion (TTE) during cycling exercise in varying warm water conditions. ⋯ Underwater exercise performance did not differ between the two acclimation strategies. This study suggests that passive acclimation to a higher water temperature may improve thermoregulatory and cardiovascular responses to exercise in warm water. Hot water immersion adaptations are dependent on exercise intensity and water temperature.
