Exercise for patients with chronic kidney disease: from cells to systems to function.

Chronic kidney disease (CKD) is among the leading causes of death and disability, affecting an estimated 800 million adults globally. The underlying pathophysiology of CKD is complex creating challenges to its management. Primary risk factors for the development and progression of CKD include diabetes mellitus, hypertension, age, obesity, diet, inflammation, and physical inactivity. The high prevalence of diabetes and hypertension in patients with CKD increases the risk for secondary consequences such as cardiovascular disease and peripheral neuropathy. Moreover, the increased prevalence of obesity and chronic levels of systemic inflammation in CKD have downstream effects on critical cellular functions regulating homeostasis. The combination of these factors results in the deterioration of health and functional capacity in those living with CKD. Exercise offers protective benefits for the maintenance of health and function with age, even in the presence of CKD. Despite accumulating data supporting the implementation of exercise for the promotion of health and function in patients with CKD, a thorough description of the responses and adaptations to exercise at the cellular, system, and whole body levels is currently lacking. Therefore, the purpose of this review is to provide an up-to-date comprehensive review of the effects of exercise training on vascular endothelial progenitor cells at the cellular level; cardiovascular, musculoskeletal, and neural factors at the system level; and physical function, frailty, and fatigability at the whole body level in patients with CKD.

Changes in opioid prescribing in veterans with headache during the COVID-19 pandemic: A regression discontinuity in time analysis.

OBJECTIVE: To determine changes in opioid prescribing among veterans with headaches during the coronavirus disease of 2019 (COVID-19) pandemic by comparing the stay-at-home phase (March 15 to May 30, 2020) and the reopening phase (May 31 to December 31, 2020). BACKGROUND: Opioid prescribing for chronic pain has declined substantially since 2016; however, changes in opioid prescribing during the COVID-19 pandemic among veterans with headaches remain unknown. METHODS: This retrospective cohort study utilized regression discontinuity in time and difference-in-differences design to analyze veterans aged ≥18 years with a previous diagnosis of headache disorders and an outpatient visit to the Veterans Health Administration (VHA) during the study period. We measured the weekly number of opioid prescriptions, the number of days supplied, the daily dose in morphine milligram equivalents (MMEs), and the number of prescriptions with ≥50 morphine equivalent daily doses (MEDD). RESULTS: A total of 81,376 veterans were analyzed with 589,950 opioid prescriptions. The mean (SD) age was 51.6 (13.5) years, 57,242 (70.3%) were male, and 53,464 (65.7%) were White. During the pre-pandemic period, 323.6 opioid prescriptions (interquartile range 292.1-325.8) were dispensed weekly, with an median (IQR) of 24.1 (24.0-24.4) days supplied and 31.8 (31.2-32.5) MMEs. Transition to stay-at-home was associated with a 7.7% decrease in the number of prescriptions (incidence rate ratio [IRR] 1.077, 95% confidence interval [CI] 0.866-0.984) and a 9.8% increase in days supplied (IRR 1.098, 95% CI 1.078-1.119). Similar trends were observed during the reopening period. Subgroup analysis among veterans on long-term opioid therapy also revealed 1.7% and 1.4% increases in days supplied during the stay-at-home (IRR 1.017, 95% CI 1.009-1.025) and reopening phase (IRR 1.014, 95% CI 1.007-1.021); however, changes in the total number of prescriptions, MME/day, or the number of prescriptions >50 MEDD were insignificant. CONCLUSION: Prescription opioid access was maintained for veterans within VHA during the pandemic. The de-escalation of opioid prescribing observed prior to the pandemic was not seen in our study.

Psychometric Properties and Sex Differences on the Mayo-Portland Adaptability Inventory Participation Subscale (M2PI) in Veterans With Traumatic Brain Injury.

OBJECTIVE: To evaluate the structural validity of the Mayo-Portland Adaptability Inventory Participation Index (M2PI) in a sample of veterans and to assess whether the tool functioned similarly for male and female veterans. DESIGN: Rasch analysis of M2PI records from the National Veterans Traumatic Brain Injury Health Registry database from 2012-2018. SETTING: National VA Polytrauma System of Care outpatient settings. PARTICIPANTS: Veterans with a clinically confirmed history of traumatic brain injury (TBI) (N=6065; 94% male). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: M2PI, a 5-point Likert-type scale with 8 items. For this analysis, the 2 employment items were treated individually for a total of 9 items. RESULTS: The employment items misfit the Rasch Measurement model (paid employment mean square [MnSq]=1.40; other employment MnSq=1.34) and were removed from subsequent iterations. The final model had eigenvalue 1.87 on the first contrast, suggesting unidimensionality of the remaining 7 items. Item order from least to most participation restriction was transportation, self-care, residence management, financial management, initiation, leisure, and social contact. Wright's person separation reliability for nonnormal distributions was 0.93, indicating appropriateness of M2PI for making individual-level treatment decisions. Mean person measure was -0.92±1.34 logits, suggesting that participants did not report restrictions on most items (item mean=0 logits). A total of 3.8% of the sample had the minimum score (no impairment on all items), and 0.2% had the maximum score. Four items had different item calibrations (≥0.25 logits) for female compared with male veterans, but the hierarchy of items was unchanged when the female sample was examined separately. CONCLUSIONS: These findings suggest that, although employment is a poor indicator of participation restrictions among veterans with TBI, the M2PI is unidimensional. Because of subtle differences in scale function between male and female participants, M2PI should be part of a more thorough clinical interview about participation strengths and restrictions.

Self-reported Participation Restrictions Among Male and Female Veterans With Traumatic Brain Injury in Veterans Health Administration Outpatient Polytrauma Programs.

OBJECTIVES: To identify areas of most restricted self-reported participation among veterans with traumatic brain injury (TBI), explore associations among participation restriction and clinical characteristics, and examine differences in participation restrictions by sex. DESIGN: Retrospective cross-sectional design. SETTING: National VA Polytrauma System of Care outpatient settings. PARTICIPANTS: Veterans with a confirmed TBI event (N=6065). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURE(S): Mayo-Portland Participation Index (M2PI), a 5-point Likert-type scale with 8 items. Total score was converted to standardized T score for analysis. RESULTS: The sample consisted of 5679 male and 386 female veterans with ≥1 clinically confirmed TBI events (69% white; 74% with blast exposure). The M2PI items with greatest perceived restrictions were social contact, leisure, and initiation. There were no significant differences between men and women on M2PI standardized T scores. Wilcoxon rank-sum analyses showed significant differences by sex on 4 items: leisure, residence, employment, and financial management (all P<.01). In multinomial logistic regression on each item controlling for demographics, injury characteristics, and comorbidities, female veterans had significantly greater relative risk for part-time work and unemployment on the employment item and significantly less risk for impairment on the residence and financial management item. CONCLUSIONS: There was no significant difference between men and women. Veterans on M2PI standardized T scores, which masks differences in response patterns to individual items. Clinical teams should be encouraged to discuss perceived restrictions with patients and target these areas in treatment planning. Future work is needed to investigate the psychometric properties of the M2PI by biological sex.

Health Care Utilization and Costs of Veterans Evaluated for Traumatic Brain Injury Through Telehealth.

Background: Mild traumatic brain injury (TBI) is prevalent among Afghanistan (Operation Enduring Freedom [OEF]) and Iraq (Operation Iraqi Freedom [OIF]) Veterans. With clinical video telehealth (CVT), Veterans screening positive for potential deployment-related TBI can receive comprehensive TBI evaluations by providers at specialized centers through interactive video communication.Introduction: We examined health care utilization and costs for Veterans during the 12 months before and after being evaluated through CVT versus in-person.Materials and Methods: We examined OEF/OIF Veterans receiving comprehensive evaluations at specialized Veterans Affairs facilities from October 2012 to September 2014. Veterans evaluated through CVT and in-person at the same facilities were included. We used a difference-in-difference analysis with propensity score weighted regression models to examine health care utilization and costs between TBI evaluation groups.Results: There were 554 Veterans with comprehensive evaluations through CVT (380 with and 174 without confirmed TBI) and 7,159 with in-person evaluations (4,899 with and 2,260 without confirmed TBI). Veterans in the in-person group with confirmed TBI had similar increases in outpatient, inpatient, and total health care costs as Veterans who had TBI confirmed through CVT. However, Veterans with a confirmed TBI evaluated in-person had greater increases in rehabilitation and other specialty costs.Discussion: When visits are in-person, Veterans may have opportunities to discuss more issues and concerns, whether TBI-related or not. Thus, providers might make more referrals to rehabilitation and specialty care after in-person visits.Conclusion: Veterans receiving in-person evaluations who were diagnosed with TBI had similar increases in health care costs as Veterans with TBI confirmed through evaluations through CVT.

Does Co-Occurring Traumatic Brain Injury Affect VHA Outpatient Health Service Utilization and Associated Costs Among Veterans With Posttraumatic Stress Disorder? An Examination Based on VHA Administrative Data.

OBJECTIVE: To examine whether a traumatic brain injury (TBI) diagnosis was associated with increased outpatient service utilization and associated costs among Iraq and Afghanistan (Operation Enduring Freedom [OEF]/Operation Iraqi Freedom [OIF]/Operation New Dawn [OND]) War veterans with posttraumatic stress disorder (PTSD) who used Veterans Health Affairs (VHA) care in a 1-year period. SETTING: N/A. PARTICIPANTS: OEF/OIF/OND veterans with a diagnosis of PTSD and/or TBI who utilized VHA services during fiscal year 2012 (N = 164 644). DESIGN: Observational study using VHA administrative data. MAIN MEASURES: Outpatient VHA utilization (total and by category of care) and associated costs (total and by VA Health Economic Resource Center cost category). RESULTS: Veterans in the comorbid PTSD/TBI group had significantly more total outpatient appointment than veterans with PTSD but no TBI. This pattern held for all categories of care except orthopedics. The comorbid TBI/PTSD group ($5769) incurred greater median outpatient healthcare costs than the PTSD ($3168) or TBI-alone ($2815) group. CONCLUSIONS: Co-occurring TBI increases the already high level of healthcare utilization by veterans with PTSD, suggesting that OEF/OIF/OND veterans with comorbid PTSD/TBI have complex and wide-ranging healthcare needs.

Traumatic brain injury clinical practice guidelines and best practices from the VA state of the art conference.

Management of symptoms following traumatic brain injury (TBI) can be complex and remains a high priority for Department of Defense (DoD) and Department of Veteran Affairs (VA). Concurrently, awareness of TBI in the public has increased. VA convened a State of the Art (SOTA) Conference to identify priorities for future research and promote best practices for TBI care. Scientific evidence of effective management of symptoms following TBI is expanding, and this evidence has been synthesized into Clinical Practice Guidelines (CPGs) and Clinical Practice Recommendations (CPRs). Knowledge gaps still exist and research efforts to address these gaps should include leveraging large administrative data sets and existing registries to determine effective treatments, investigate compliance of existing clinical care with CPGs and study limitations to determine modifiable vs. non-modifiable core tenants of the evidence-based treatments.

Affective and Cognitive Conditions are Stronger Predictors of Success with Community Reintegration than Gait and Balance Performance in Veterans with Mild Traumatic Brain Injury.

INTRODUCTION: Optimal community reintegration is an integral part of the clinical management of patients with mild traumatic brain injury. BACKGROUND/OBJECTIVE: We sought the contribution and inter-relation of such variables as balance, executive function, and affective regulation to the community reintegration of veterans with mTBI. METHODS: We examined the statistical relationship among the above variables by conducting a series of objective evaluations to assess the balance, gait, executive function, affective regulation, and scores representing the patients' issues with community reintegration. The data were statistically analyzed for correlation and regression. RESULTS: High correlation was found among scores for balance and gait, executive function and affective regulation. The first and second best predictors of success with patient's community reintegration were data representing affective regulation and cognitive impairments, respectively. However, the data for dynamic balance correlated weakly and insignificantly with scores for the three subsets of community reintegration. CONCLUSIONS: We revealed varying degrees of correlation among balance, executive function and affective regulation, and as they related to the community reintegration success of patients with mTBI. The strongest, intermediate and weakest predictors for these patients' success with community reintegration represented those for affective regulation, executive function, and dynamic balance and gait performance, respectively.

Deconstructing Chronic Low Back Pain in the Older Adult-Step-by-Step Evidence and Expert-Based Recommendations for Evaluation and Treatment: Part XII: Leg Length Discrepancy.

OBJECTIVE: To present the last in a 12-part series designed to deconstruct chronic low back pain (CLBP) in older adults. This article focuses on leg length discrepancy (LLD) and presents an algorithm outlining approaches to diagnosis and management of LLD in older adults, along with a representative clinical case. METHODS : Using a modified Delphi approach, the LLD evaluation and treatment algorithm was developed by a multidisciplinary expert panel representing expertise in physical therapy, geriatric medicine, and physical medicine and rehabilitation. The materials were subsequently refined through an iterative process of input from a primary care provider panel comprised of VA and non-VA providers. The clinical case was taken from one of the authors. RESULTS : We present an algorithm and illustrative clinical case to help guide the care of older adults with LLD, which can be an important contributor to CLBP. Firstline assessment includes referral to physical therapy or orthopedics, depending on the context of the LLD. A variety of nonsurgical interventions may ensue depending on the etiology of the LLD, including shoe inserts, customized shoes, manual therapy, or a combination. CONCLUSIONS : To promote a patient-centered approach, providers should consider evaluating for leg length discrepancy when treating older adults with CLBP to help diminish pain and disability.

Deconstructing Chronic Low Back Pain in the Older Adult-Step by Step Evidence and Expert-Based Recommendations for Evaluation and Treatment: Part X: Sacroiliac Joint Syndrome.

OBJECTIVE: To present an algorithm of sequential treatment options for managing sacroiliac joint (SIJ) pain in the setting of chronic low back pain (CLBP) in the older adult. This is the tenth part in a series, and includes an illustrative clinical case. METHODS: The stepped care drug table and evaluation and treatment algorithm were created following a thorough literature review of approaches and subsequent analysis through a modified Delphi process. The principal investigator developed the initial draft, which was refined for content by an interdisciplinary panel of five experts. The refined materials were then assessed for the feasibility of implementation and validity of recommendations for older adults in a primary care setting by a panel of nine primary care providers. While not exclusive to Veteran's Health Administration (VHA) facilities, an emphasis was made to include resources and medications available to providers in the VHA. RESULTS: The algorithm and drug table developed to systematically identify and address SIJ pain in the older adult is presented here. The process should begin with recognizing the presenting symptoms of CLBP stemming from the SI region, and supporting physical exam testing using the compression test and thigh thrust maneuver. Identification of the SIJ as a pain generator is followed by assessment and treatment of contributory factors. SIJ pain treatment should begin with education and self-management including exercise, and may escalate to include interventional procedures and/or referral to a pain rehabilitation program. CONCLUSIONS: Pain originating from the SIJ is often under-recognized, but a structured and consistent approach can help identify older patients who would benefit from treatment of this contributor to CLBP. KEY WORDS: Chronic Low Back Pain; Sacroiliac Joint Pain; Older Adults.

Deconstructing Chronic Low Back Pain in the Older Adult-Step by Step Evidence and Expert-Based Recommendations for Evaluation and Treatment: Part II: Myofascial Pain.

OBJECTIVE: To present an algorithm of sequential treatment options for managing myofascial pain (MP) in older adults, along with a representative clinical case. METHODS: A modified Delphi process was used to synthesize evidence-based recommendations. A multidisciplinary expert panel developed the algorithm, which was subsequently refined through an iterative process of input from a primary care physician panel. RESULTS: We present an algorithm and supportive materials to help guide the care of older adults with MP, an important contributor to chronic low back pain (CLBP). Addressing any perpetuating factors should be the first step of managing MP. Patients should be educated on self-care approaches, home exercise, and the use of safe analgesics when indicated. Trigger point deactivation can be accomplished by manual therapy, injection therapy, dry needling, and/or acupuncture. CONCLUSIONS: The algorithm presented gives a structured approach to guide primary care providers in planning treatment for patients with MP as a contributor to CLBP.

Home Clinical Video Telehealth Promotes Education and Communication with Caregivers of Veterans with TBI.

Ongoing communication and care coordination are essential among patients, their family, and interdisciplinary rehabilitation team members to address the complex and changing rehabilitation needs of traumatic brain injuries. Family members of patients with traumatic brain injury commonly assume a caregiver role following discharge from inpatient rehabilitation. The Department of Veterans Affairs has adopted clinical video telehealth to promote access to care, and use of clinical video telehealth for rehabilitation is expanding. Recent implementation of home clinical video telehealth can assist with the ongoing management and treatment of patients in their home setting. This report demonstrates enhanced education and care coordination by using clinical video telehealth with a Veterans Affairs-eligible beneficiary receiving treatment for traumatic brain injury.

Analysis of US Veterans Health Administration comprehensive evaluations for traumatic brain injury in Operation Enduring Freedom and Operation Iraqi Freedom Veterans.

OBJECTIVE: To describe neurobehavioural symptoms in Iraq and Afghanistan war veterans evaluated for traumatic brain injury (TBI) through the Veterans Health Administration (VHA) TBI screening and evaluation programme. DESIGN: An observational study based on VHA administrative data for all veterans who underwent TBI Comprehensive Evaluation between October 2007 and June 2010. RESULTS: 55,070 predominantly white, non-Hispanic, male Veterans with a positive TBI screen had comprehensive TBI evaluations completed during the study period. Moderate-to-severe symptoms were common in the entire sample, both in those with and without a clinician-diagnosed TBI. However, the odds of reporting symptoms of this severity were significantly higher in those diagnosed with TBI compared to those without a TBI diagnosis, with odds ratios ranging from 1.35-2.21. TBI-specialty clinicians believed that in the majority of diagnosed TBI cases both behavioural health conditions and TBI contributed to patients' symptom presentation. CONCLUSIONS: The VHAs TBI screening and evaluation process is identifying individuals with ongoing neurobehavioural symptoms. Moderate-to-severe symptoms were more prevalent in veterans with TBI-specialty clinician determined TBI. However, the high rate of symptom reporting also present in individuals without a confirmed TBI suggest that symptom aetiology may be multi-factorial in nature.

Characteristics and Gender Differences of Headache in the Veterans Health Administration: A National Cohort Study, Fiscal Year 2008-2019.

BACKGROUND AND OBJECTIVES: - To determine gender differences in headache types diagnosed, sociodemographic characteristics, military campaign and exposures, and healthcare utilization among United States (U.S.) Veterans in the Veterans Health Administration (VHA). METHODS: - This study employed a retrospective cohort design to examine VHA Electronic Health Record (EHR) data. This cohort includes Veterans who had at least one visit for any headache between fiscal years 2008 and 2019. Headache diagnoses were classified into eight categories using International Classification of Disease, Clinical Modification codes. Demographics, military-related exposures, comorbidities, and type of provider(s) consulted were extracted from the EHR, and compared by gender. Age-adjusted incidence and prevalence rates of medically diagnosed headache disorders were calculated separately for each type of headache. RESULTS: - Of the 1,524,960 Veterans with headache diagnoses included in the cohort, 82.8% were men. Compared with women, men were more often white (70.4% vs 56.7%), older (52.0±16.8 vs 41.9±13.0 years), with higher rates of traumatic brain injury (2.9% vs 1.1%) and post-traumatic stress disorder (23.7% vs 21.7%), and lower rates of military sexual trauma (3.2% vs 33.7%; p<0.001 for all). Age adjusted incidence rate of headache of any type was higher among women. Migraine and trigeminal autonomic cephalalgias rates were most stable over time. Men were more likely than women to be diagnosed with headache not-otherwise-specified (77.4% vs 67.7%) and have higher incidence rates of headaches related to trauma (3.4% vs 1.9% [post-traumatic]; 5.5% vs 5.1% [post-whiplash]; p <0.001 for all). Men also had fewer headache types diagnosed (mean ± standard deviation; 1.3 ± 0.6 vs 1.5 ± 0.7), had fewer encounters for headache/year (0.8 ± 1.2 vs 1.2 ± 1.6) and fewer visits to headache specialists (20.8% vs 27.4% p <0.001 for all), compared to women. Emergency Department utilization for headache care was high for both genders and higher for women compared to men (20.3% vs 22.9%; p<0.001). DISCUSSION: - Among Veterans with headache diagnoses, important gender differences exist for men and women Veterans receiving headache care within VHA regarding sociodemographic characteristics, headache diagnoses, military exposure, and headache healthcare utilization. The findings have potential implications for providers and the healthcare system caring for Veterans living with headache.

Physical Activity, Exercise, Whole Health, and Integrative Health Coaching.

Physical activity and exercise play a significant role in the management and prevention of chronic disease. Therefore, patient-center approaches offered within medical settings are essential for the promotion of health and well-being. The Whole Health model of care incorporates all aspects of care, including prevention, treatment, conventional, and complementary approaches resulting in care for the whole person. Integrative health coaching is a tool for clinicians seeking to achieve behavior changes for improved health, particularly in the areas of physical activity and exercise. The Whole Health model of care complements the rehabilitative process, using a combination of complementary and integrative medicine for health promotion. In addition to incorporating Whole Health tools into clinical care, rehabilitative specialists may partner with integrative health coaches to achieve challenging behavior changes in the areas of physical activity, exercise, and other areas of self-care.

Gender Differences in Outcomes after Traumatic Brain Injury among Service Members and Veterans.

This scoping study describes the range of outcomes in traumatic brain injury (TBI) studies of military service members and veterans addressing gender differences. A secondary purpose is to identify differences in outcomes between male and female participants in such studies. We searched PubMed, CiNAHL, and PsycInfo databases for relevant articles. Two reviewers independently screened results. Of 822 unique titles and abstracts screened for eligibility, 55 full articles were reviewed, with 29 studies meeting full inclusion criteria. Twenty of the 29 included studies used retrospective designs and all but two used data collected from Veterans Affairs or Department of Defense health care settings. TBI was diagnosed by self-report, screening, and evaluation procedures, and medical record documentation. Ten different outcome categories were identified among the included studies. In general, female service members and veterans have not been well represented in TBI outcomes research. Evidence suggests that female veterans with mild TBI (mTBI) report more neurobehavioral symptoms and use more outpatient services than male veterans. Studies also indicate that female veterans with TBI are more frequently diagnosed with depression. Additional research is essential to support precision treatment recommendations for female veterans with TBI, as women represent a growing proportion of the patients served by the Veterans Health Administration. LEVEL OF EVIDENCE: IV.

Ten-Year Outcomes of a Systems-Based Approach to Longitudinal Amputation Care in the US Department of Veteran Affairs.

BACKGROUND: The goal of the US Department of Veterans Affairs (VA) Amputation System of Care (ASoC) is to enhance the quality and consistency of amputation rehabilitation care for veterans with limb loss. OBJECTIVE: The ASoC provides specialized expertise in amputation rehabilitation incorporating the latest practices in medical management, rehabilitation, and artificial limbs in order to minimize disability and to enable the highest level of social, vocational, and recreational success for veterans with amputation. DISCUSSION: The ASoC serves veterans with limb amputation from any etiology. Between 2009 and 2019, the VA experienced a 34% increase in the number of veterans with amputation who received care. During the same 10-year period, the percentage of veterans with major limb amputation seen in an outpatient amputation specialty clinic each year increased from 4.8 to 26%. This article highlights how the mission of the ASoC has been accomplished over the past decade through prioritization and implementation of key strategic initiatives in learning organization creation, trust in VA care, modernization, and development of a high-performance network with enhanced access and customer service. CONCLUSIONS: This synopsis of the VA amputation care program serves as a model of amputation care that can be utilized outside the federal sector and has the potential to serve as a systems-based example for providing longitudinal care to other populations within the VA.

Preliminary Study of the Effects of Eccentric-Overload Resistance Exercise on Physical Function and Torque Capacity in Chronic Kidney Disease.

The purpose of this preliminary study was to describe changes in physical function and torque capacity in adults with chronic kidney disease (CKD) in response to a novel progressive eccentric-overload resistance exercise (ERE) regime. Participants included men (n = 4) diagnosed with CKD according to estimated glomerular filtration rate (eGFR) between 59 and 15 mL/kg/1.73 m2 and not requiring dialysis. Physical function was determined by the Short Physical Performance Battery (SPPB), five repetitions of a sit-to-stand (STS) task, and timed-up and go (TUG). Knee extensor strength was assessed using both isometric and isokinetic contractions and performance fatigability indexes were calculated during a 30-s maximal isometric test and a 30-contraction isokinetic test at 180°/second. None of the patients exhibited significant worsening in their health status after training. Participants demonstrated improvements in several measures of physical function and torque capacity following 24 sessions of ERE. Following training, performance fatigability remained relatively stable despite the increases in torque capacity, indicating the potential for greater fatigue resistance. These findings provide initial evidence for ERE as a potential treatment option to combat declines in physical function and neuromuscular impairments in people with CKD. Future research is required to determine optimal progression strategies for maximizing specific neuromuscular and functional outcomes when using ERE in this patient population.

Comparison of pain and emotional symptoms in soldiers with polytrauma: unique aspects of blast exposure.

OBJECTIVES: To compare the physical and emotional presentation and pain treatment outcomes of service members who sustained polytrauma secondary to blast with those of soldiers injured by other means. DESIGN: Retrospective medical record review. SETTING AND PATIENTS: One of four Veterans Affairs multidisciplinary inpatient Polytrauma Rehabilitation Centers. One hundred twenty-eight Operation Enduring Freedom and Operation Iraqi Freedom military personnel with serious polytrauma injuries and concomitant pain categorized into three groups based on type of injuries: blast injuries, combat injuries other than blast, and noncombat, nonblast injuries. INTERVENTIONS: Intensive, interdisciplinary inpatient rehabilitation and pain treatment. OUTCOME MEASURES: Pain intensity ratings; Functional Independence Measure scores; Rancho Los Amigos levels; and opioid analgesic doses. RESULTS: Service members injured via blast demonstrated a broader spectrum of physical injuries, higher levels of admission and discharge opioid analgesic use, reduced improvement in pain intensity following treatment, and much higher rates of posttraumatic stress disorder and other psychiatric diagnoses than those injured via other means. CONCLUSIONS: Blast injury may be associated with differential physical, emotional, and pain-related symptoms that pose increased challenges for successful treatment.
