Hyperkalemia is a common electrolyte abnormality with characteristic electrocardiogram changes. Both angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs) increase the risk of developing hyperkalemia. This case highlights a rare life-threatening episode of hyperkalemia in an individual whose only risk factor was an ARB. ⋯ While both ARBs and ACEIs are commonly associated with mild hyperkalemia, life-threatening hyperkalemia is rare, particularly in patients without concomitant renal failure, diabetes mellitus, adrenal disease, or potassium-sparing diuretic use. However, this case illustrates that life-threatening hyperkalemia is possible in patients solely taking an ARB without prior significant risk factors. Despite normal renal function in an individual without heart failure or diabetes, this patient developed life-threatening hyperkalemia.

Military operations provide a unified action and strategic approach to achieve national goals and objectives. Mortality reviews from military operations can guide injury prevention and casualty care efforts. ⋯ Comprehensive mortality reviews should routinely be conducted for all military operation deaths. Understanding death from both injury and disease can guide preemptive and responsive efforts to reduce death among military forces.

Traumatic brain injury (TBI) can trigger vision-based sequelae such as oculomotor and accommodative abnormalities, visual-vestibular integrative dysfunction, visual field loss, and photosensitivity. The need for diagnosis and management of TBI-related vision impairment has increased because of the increasing frequencies of combat warfighters returning from Iraq and Afghanistan with TBIs. The purpose of this research was to learn the sequelae of rehabilitation service delivery to veterans with TBI-related visual dysfunction after they are diagnosed. To accomplish this, we investigated vision rehabilitation assessments and interventions provided to veterans with TBI-related visual dysfunction at the Department of Veterans Affairs (VA) specialty polytrauma facilities for the 2 years following their injury. The research questions asked what assessments, interventions, and prescribed assistive devices were provided by VA specialty clinics (e.g., occupational therapy, polytrauma, and blind rehabilitation) and how service delivery was affected by demographic and clinical variables. ⋯ The delivery of patient services should be driven by the needs of veterans and not by system-level factors such as the availability of specific vision rehabilitation services at specific locations. Traditional low vision and blind rehabilitation programs were not designed to treat the comorbidities and symptoms associated with TBI. To address this challenge, blind rehabilitation and neurologic recovery cross training is needed. Our findings document how five VA Polytrauma Rehabilitation Centers implemented this training in 2008. The next step is to extend and standardize this new paradigm to community care, where these post-deployment patients now reside.

The healthy soldier effect (HSE) describes a phenomenon of enduring health and lower mortality among veterans due in part to initial screening procedures and health care access. Although early data were supportive of a broad HSE among former military members, more recent investigations have suggested a possible attenuation of the effect with older age. The present study aimed to provide an update of the HSE using an expansive Veterans Health Administration (VHA)-wide sample with a particular focus on age and sex effects. ⋯ This is the largest investigation to date examining the HSE in U.S. veterans and includes younger veterans from more recent military eras. Higher mortality among the 55- to 74-year age groups merits further investigation, as does the relatively higher mortality among older female veterans. Our findings have implications for the provision of health care and preventative care to these veterans most at risk for higher mortality.

The U.S. Army is updating the physical fitness assessment for soldiers to the six-event Army Combat Fitness Test (ACFT). A paucity of data regarding the ACFT maximum deadlift (MDL) event, especially in military populations, has increased concern over the objectivity of the test. The reliability of scoring the MDL has not been established. It is unknown if grader professional experience impacts the reliability of scoring, and if so, what level of experience is required for reliable assessment. Performance and assessment of the MDL could impact military occupational selection, promotion, and retention within the Army. The purposes of this study were to determine the inter- and intra-rater reliabilities of raters with varying degrees of professional experience on scoring the MDL and to determine the relationships between load lifted, overall lift success, sex, and body mass index (BMI). ⋯ Inter-rater reliability of the six raters ranged from poor to substantial, while intra-rater reliability ranged from moderate to excellent. Compared to a reference standard, inter-rater reliability ranged from poor to substantial. The wide range in consistency demonstrated in this study, both between and within raters, brings into question the current subjective methods used to grade the MDL. More research is needed to understand the most feasible, valid, and reliable way to assess performance standards like the MDL that may affect a soldier's career progression.
