RESUMEN
Traumatic brain injury (TBI) is highly prevalent among a wide range of populations, including civilians, military personnel, and Veterans. TBI sequelae may be further exacerbated by symptoms associated with frequently occurring comorbid psychiatric conditions, including posttraumatic stress disorder (PTSD). This is particularly true among the population of military personnel from recent conflicts in Iraq and Afghanistan, with a history of mild TBI (mTBI) and PTSD. The need for efficacious treatments for TBI and comorbid PTSD is significant, and evidence-based interventions for these frequently co-occurring conditions are limited. Based on findings suggesting that inflammation may be an underlying mechanism of both conditions, anti-inflammatory/immunoregulatory agents, including probiotics, may represent a novel strategy to treat TBI and/or PTSD-related symptoms. The focus of this systematic review was to identify and evaluate existing research regarding prebiotic and probiotic interventions for the populations of individuals with a history of TBI and/or PTSD. Only 4 studies were identified (3 severe TBI, 1 PTSD, 0 co-occurring TBI and PTSD). Although findings suggested some promise, work in this area is nascent and results to date do not support some claims within the extensive coverage of probiotics in the popular press.

BACKGROUND: Although Veterans utilize complementary and alternative medicine (CAM) at rates comparable with civilians, little is known about Veterans' attitudes and beliefs toward CAM. Measures to increase such knowledge may help to identify treatment preferences, particularly among those with signature conditions from the recent conflicts [ie, traumatic brain injury (TBI), posttraumatic stress disorder (PTSD)]. OBJECTIVE: This exploratory study aimed to: (1) determine the factors of the Complementary, Alternative, and Conventional Medicine Attitudes Scale (CACMAS); and to utilize the resulting factors to describe (2) attitudes and beliefs toward CAM; (3) their association with TBI, PTSD, and history of self-directed violence. Patterns of CAM use were also obtained. RESEARCH DESIGN: Factor analysis. Observational study. SUBJECTS: Participants were 97 Veterans seeking care at a Mountain State Veterans Affairs Medical Center. METHODS: Participants completed the CACMAS, clinical interviews, and self-report measures during a single visit. RESULTS: CACMAS factors identified were: acceptability of (1) CAM and (2) conventional medicine; (3) mind-body integration; and (4) belief in CAM. Acceptability of CAM was significantly associated with history of mild TBI (mTBI) or PTSD symptom severity. Veterans endorsed a wide range of CAM use. CONCLUSIONS: Veterans in this sample were open to CAM and conventional medicine, believed in CAM, and believed that treatments should incorporate the mind and body. Veterans with a history of mTBI or PTSD symptoms may be more accepting of CAM. Understanding Veterans' beliefs and attitudes regarding CAM may help providers deliver patient-centered treatments, particularly among those with conditions for which evidence-based interventions are limited (eg, mTBI).

It is widely accepted that suicidal behavior often occurs with little planning. We propose, however, that suicidal behavior is rarely if ever impulsive-that it is too frightening and physically distressing to engage in without forethought-and that suicidal behavior in impulsive individuals is accounted for by painful and fearsome behaviors capable of enhancing their capacity for suicide. We conducted a meta-analysis of the association between trait impulsivity and suicidal behavior and a critical review of research considering the impulsiveness of specific suicide attempts. Meta-analytic results suggest the relationship between trait impulsivity and suicidal behavior is small. Furthermore, studies examining a mediating role of painful and provocative behaviors have uniformly supported our model. Results from our review suggest that researchers have been unable to adequately measure impulsivity of attempts and that measures sensitive to episodic planning must be developed to further our understanding of this phenomenon.

BACKGROUND: Sport-related concussion (SRC) is a heterogenous injury that often presents with varied symptoms and impairment. Recently, research has focused on identifying subtypes, or clinical profiles of concussion to be used in assessing and treating athletes with SRC. The purpose of this study was to investigate sex differences in clinical profiles, recovery duration, and initial symptom severity after SRC in a cohort of collegiate athletes in the Pacific-12 Conference (Pac-12). METHODS: This prospective cohort study examined post-SRC symptoms, recovery, and return-to-play times using data from the Pac-12 CARE Affiliated Program and Pac-12 Health Analytics Program. Clinical profiles reported by student-athletes were defined by the number (> 50%) of specific symptoms frequently reported for each profile. Generalized linear mixed models were used to examine associations among sex, clinical profiles, time-to-recovery, and return-to-play times. RESULTS: 479 concussion incidents met inclusion criteria. The probabilities of initial presentation of each clinical profile, initial injury severity scores, and recovery times within a profile did not differ between sexes (p = 0.33-0.98). However, both males and females had > 0.75 probabilities of exhibiting cognitive and ocular profiles. Initial injury severity score was a strong nonlinear predictor of initial number of clinical profiles (p < 0.0001), which did not differ between sexes. The number of clinical profiles was also a nonlinear predictor of time-to-recovery (p = 0.03) and return-to-play times (p < 0.0001). CONCLUSIONS: Initial symptom severity was strongly predictive of the number of acute clinical profiles experienced post-SRC. As the number of clinical profiles increased, time-to-recovery and time to return-to-play also increased. Factors other than sex may be better associated with acute symptom presentation post-concussion as no sex differences were found in reported clinical profiles or recovery. Understanding the number and type of clinical profiles experienced post-SRC may help inform concussion diagnostics and management.
RESUMEN
Mild traumatic brain injury (mTBI) is the most common form of TBI, with more than 2.5 million TBI cases in the United States annually. Identification of easily obtainable biomarkers that track strongly with mTBI symptoms may improve our understanding of biological factors that contribute to mTBI symptom profiles and long-term outcomes. Notably, some individuals with mTBI exhibit circadian disruptions and elevated stress sensitivity, which in other clinical groups often correlate with disrupted secretion of cortisol, a glucocorticoid hormone that coordinates circadian and stress physiology. Here, we examined whether cortisol profiles could serve as a biomarker to complement the assessment of neurobehavioral sequelae after mTBI. We partnered with our on-campus health clinic to recruit college students seeking medical care after mTBI (n = 46) and compared this population to a well-matched non-injured student control group (n = 44). We collected data at an initial visit (shortly after injury in mTBI subjects) and one week later. At each visit, we evaluated neurobehavioral function using the Automated Neuropsychological Assessment Metric (ANAM). The subjects also provided cortisol samples through at-home saliva collection. We observed strong coherence between ANAM subjective and objective measures, indicating significant multi-dimensional impairment in subjects with mTBI. Further, female mTBI subjects exhibited diminished neurobehavioral function compared with males. Regardless of sex, decreased amplitude of diurnal cortisol and a blunted cortisol awakening response were associated with mTBI symptom severity and neurobehavioral impairment. Taken together, these findings suggest that salivary cortisol profiles may be a sensitive biomarker for studying underlying biological factors that impact mTBI symptoms and outcomes.

Mild traumatic brain injury (mTBI) is one of the most common injuries experienced by Veterans and can frequently result in a variety of post-concussive symptoms. Post-concussive headaches (PCH), one of the most common symptoms, can persist for years after the injury occurred. The long-lasting impacts of PCH can be extremely distressing for Veterans, thus necessitating the need to find reliable biomarkers that directly relate to subjective feelings of distress. Yoga-based interventions have been shown to improve both subjective and objective markers of stress. Techniques used in yoga, such as the focus on releasing muscular tension, are also recommended as strategies for treating PCH. Thus, yoga-based interventions provide a unique context for the comparison of subjective and objective measures of distress in Veterans with PCH. In this secondary, exploratory analysis, we examined the relationship between perceived distress and cortisol in sixteen Veterans with mTBI and long-term PCH within the context of a yoga intervention feasibility study. The Visual Analogue Scale (VAS), a validated tool for measuring subjective distress, was administered to participants immediately before and after 75-min yoga classes, which occurred twice weekly over eight weeks. Participants also provided salivary cortisol (pre- and post-yoga) at in-person sessions (eight) to compare to changes in VAS scores. We found that VAS scores were significantly reduced within five of the eight assessed yoga classes, but there were no significant changes in cortisol levels. No significant correlations were found between VAS scores and salivary cortisol levels. When looking at how cortisol levels changed over time (i.e., over the series of eight yoga sessions), there was a significant downward trajectory in post-yoga cortisol, but not after taking pre-class cortisol into account (i.e., within yoga session cortisol change over time). Taken together, we found that subjective distress, but not cortisol was reduced by yoga classes. These data suggest that salivary cortisol did not match changes in perceived distress, thus emphasizing the ongoing challenges of relating subjective and objective measures.
RESUMEN
BACKGROUND: Mild traumatic brain injury (mTBI) is a signature injury sustained by Veterans during recent conflicts. For some, mTBI/concussion is associated with disabling symptoms, including post-concussive headaches (PCH). However, there are limited evidence-based treatments for persistent PCH. OBJECTIVE: Investigators assessed the feasibility of design elements of a yoga-based interventional trial for PCH among Veterans, as well as the acceptability of the intervention. METHODS: This randomized controlled acceptability and feasibility trial was implemented using a waitlist-control design. Design elements of interest included: an exercise run-in class; recruitment and retention strategies; and, ecological momentary assessment (EMA) modalities to track headaches and yoga practice. Veteran satisfaction regarding the intervention was also evaluated. A descriptive analysis was conducted on candidate outcomes including PCH, post-concussive symptoms, pain, and daily functioning. RESULTS: Twenty-seven participants (out of 70 consented and eligible after Study Visit 1) completed each evaluation timepoint and regularly attended yoga sessions, with 89% of these Veterans reporting moderate to high levels of satisfaction with the intervention at study completion. Qualitatively, participants endorsed improvements in headaches, chronic pain, and mood. Feasibility results were mixed. Initial feasibility criterion regarding yoga attendance was not met; however, modifications, such as expansion to an additional clinic site and reduction of in-person yoga sessions with increased encouragement to use study-created online yoga videos improved feasibility of the study design. Participants most frequently used mobile and web-based EMA modalities to track yoga practice. CONCLUSIONS: Although challenges with feasibility of the study design elements were noted, results suggested acceptability of the yoga-based intervention for Veterans with persistent PCH. Additional exploration regarding the frequency and modality of yoga delivery (e.g., in-person, telehealth) is warranted. IMPACT: Veterans found the yoga-based intervention acceptable, however exploration of novel modalities of intervention delivery will likely be necessary to enhance the feasibility of intervention implementation during future trials.
RESUMEN
Sport-related concussion has garnered increasing scientific attention and research over the last decade. Collegiate student-athletes represent an important cohort in this field. As such, the Pac-12 CARE-Affiliated Program (CAP) was formed in 2017 as a regional hub of the Concussion Assessment, Research and Education (CARE) consortium. CAP is multisite, prospective, longitudinal study that aims to improve student-athlete health by identifying factors associated with concussion incidence and recovery and using this knowledge to inform best clinical practices and policy decisions. CAP employed a staggered rollout across the Pac-12, with the first four institutions enrolling in fall 2018. After receiving institutional review board (IRB) approval, these institutions began consenting student-athletes to share clinical concussion and baseline data for research purposes. Athletes completed baseline testing that included a medical questionnaire, concussion history and a battery for clinical concussion assessments. Concussed student-athletes were given the same battery of assessments in addition to full injury and return to play reports. Clinicians at each university worked with a data coordinator to ensure appropriate reporting, and the Pac-12 Concussion Coordinating Unit at the University of Colorado Boulder provided oversight for quality control of the data study wide. During year 1, CAP consented 2181 student-athletes and tracked 140 concussions. All research was conducted with the appropriate IRB approval across the participating Pac-12 institutions. Data security and dissemination are managed by the Presagia Sports Athlete Electronic Health Record software (Montreal, Quebec, Canada) and QuesGen Systems (San Francisco, California, USA).
RESUMEN
OBJECT: The sport of triathlon is very physically demanding and has experienced rapid growth in recent years. The number of triathletes seen for spine disorders at neurosurgery clinics is increasing. Neck pain and overuse injuries have not been adequately studied in multisport athletes. The authors undertook an epidemiological study to establish the lifetime incidence of neck pain and the prevalence of possible discogenic pain, and to identify risk factors among triathletes in the Boulder, Colorado area. METHODS: An online questionnaire was developed to collect information about physical characteristics, training habits, athletic status, number of races completed, and neck pain among triathletes. The incidence of possible cervical discogenic pain was defined according to the duration of symptoms for the most recent pain episode. RESULTS: One hundred and sixty-four athletes responded to the questionnaire. The lifetime incidence of neck pain was 47.6% (78 athletes), with 15.4% possibly being of discogenic origin based on the duration of symptoms. Approximately 64% of responding athletes reported that their neck pain was sports related. Although the number of previous triathlons was not predictive of neck pain, total years in the sport (p = 0.029) and number of previous sports-related injuries (p < 0.0001) were. CONCLUSIONS: Two major risk factors for long-term spinal problems in triathletes are sports-related injuries and overuse. This report is one of the first comprehensive studies of neck pain and overuse injury in multisport athletes.

There are an estimated 2 million traumatic brain injuries (TBIs) each year in the United States, making the yearly incidence eight times greater than that of breast cancer and 34 times greater than HIV/AIDS. Still, it remains a "silent epidemic" because TBI results in persistent neurobehavioral impairment, without necessarily imparting a physical scar. The present review is a comparative analysis of TBI research, both basic and applied, outlining the evidence that at least one component of the brain's innate response to insult (e.g., post-traumatic neural depression) is sufficiently well understood to be the target of additional clinical studies and therapeutic strategy development.

OBJECT: As the sport of triathlon has continued to grow, increasing numbers of triathletes have presented in the neurosurgery clinics with various spinal disorders. This epidemiological study was undertaken to establish the lifetime incidence of neck and back pain, to gauge the prevalence of discogenic pain, and to identify risk factors among triathletes in the Boulder, Colorado, area. METHODS: A live online questionnaire was developed that was used to collect information about physical characteristics, training habits, athletic status, number of races completed, and back pain among triathletes. The incidence of cervical and/or lumbar discogenic back pain was defined according to the duration of symptoms for the most recent pain episode. The lifetime incidence of low-back pain was 67.8%, with 23.7% of cases possibly being discogenic in origin. The number of triathlons in which the respondents had participated and the presence of previous sports-related injuries were predictive of low-back pain (p = 0.02 and p < 0.00001, respectively). The lifetime incidence of neck pain was 48.3%, with 21.4% of cases being consistent with intervertebral disc involvement. The number of previous sports-related injuries was predictive of neck pain (p < 0.00001), and a strong tendency toward neck pain was observed for athletes with more total years of participation in sports (p = 0.06). CONCLUSIONS: The two main risk factors for long-term spinal problems include sports-related injuries and overuse. The study results definitely support the influence of both mechanisms for low-back pain. Neck pain was associated with an injury event, and a strong (although not statistically significant) tendency toward neck pain was observed in respondents with overuse injuries.

Traumatic brain injury (TBI) is highly prevalent and occurs in a variety of populations. Because of the complexity of its sequelae, treatment strategies pose a challenge. Given this complexity, TBI provides a unique target of opportunity for complementary and alternative medicine (CAM) treatments. The present review describes and discusses current opportunitites and challenges associated with CAM research and clinical applications in civilian, veteran and military service populations. In addition to a brief overview of CAM, the translational capacity from basic to clinical research to clinical practice will be described. Finally, a systematic approach to developing an adoptable evidence base, with proof of effectiveness based on the literature will be discussed. Inherent in this discussion will be the methodological and ethical challenges associated with CAM research in those with TBI and associated comorbidities, specifically in terms of how these challenges relate to practice and policy issues, implementation and dissemination. This article is part of a Special Issue entitled SI:Brain injury and recovery.

The effects of propentofylline, a xanthine derivative and adenosine transport inhibitor, were evaluated following anteromedial cortex lesion in the rat. Propentofylline (2x/10 mg/kg, intraperitoneally) was administered for 7 days post-insult and basic fibroblast growth factor (bFGF) immunoreactivity measured at designated time points in the peri-lesional cortex and ipsilateral dorsal striatum. The spatiotemporal pattern of bFGF expression was then compared to functional recovery patterns. Propentofylline-treated animals displayed increased bFGF expression in the peri-lesional cortex which may have contributed to the observed early facilitation of functional recovery. Drug administration did not, however, produce a change in bFGF expression in the ipsilateral dorsal striatum compared to saline-treated animals. These findings taken together with other positive findings regarding propentofylline, support the drug's therapeutic potential.

Military personnel are returning from Iraq and Afghanistan and reporting non-specific physical (somatic), behavioral, psychological, and cognitive symptoms. Many of these symptoms are frequently associated with mild traumatic brain injury (mTBI) and/or post traumatic stress disorder (PTSD). Despite significant attention and advances in assessment and intervention for these two conditions, challenges persist. To address this, clinically relevant blast models are essential in the full characterization of this type of injury, as well as in the testing and identification of potential treatment strategies. In this publication, existing diagnostic challenges and current treatment practices for mTBI and/or PTSD will be summarized, along with suggestions regarding how what has been learned from existing models of PTSD and traditional mechanism (e.g., non-blast) traumatic brain injury can be used to facilitate the development of clinically relevant blast models.
RESUMEN
OBJECTIVES: Identifying a non-pharmacological intervention to reduce the stress response could be particularly beneficial to college students, a group prone to considerable stress. Acupressure has shown some efficacy in reducing stress in adults following stroke or traumatic brain injury (TBI), but multiple treatments were required. Results from single treatments in healthy populations have been mixed. DESIGN: The current study used a randomised, placebo-controlled, single-blind design to investigate the use of a single acupressure treatment for stress reduction in healthy college students (n=109) during a stressor. INTERVENTIONS: Participants were randomly assigned to one of three single, 40-min interventions: active acupressure, placebo acupressure, or a relaxation CD control. A math task stressor administered before and after the intervention assessed intervention effects on stressor responsivity. MAIN OUTCOME MEASURES: Stress responses were measured by physiological (heart rate (HR), heart rate variability (HRV), skin conductance response (SCR)) and subjective measures (State Anxiety Inventory, nine-item Psychological Stress Measure) of anxiety and stress. RESULTS: All interventions were associated with the following changes during the post-intervention stressor compared to the pre-intervention stressor: reduced HR (p<0.001), increased HRV (p<0.024), reduced SCR (p<0.001), reduced subjective stress scores (p<0.001), and increased correct answers (p<0.001). Although all groups demonstrated stress reduction, there were no significant group differences after a single treatment. CONCLUSIONS: All interventions significantly reduced the stress response, although not differently. The lack of active acupressure-associated treatment effects appears to be due to insufficient dosing.

Acupressure is a complementary and alternative medicine (CAM) treatment using fingertips to stimulate acupoints on the skin. Although suggested to improve cognitive function, acupressure has not been previously investigated with a controlled design in traumatic brain injury (TBI) survivors, who could particularly benefit from a non-pharmacological intervention for cognitive impairment. A randomized, placebo-controlled, single-blind design assessed the effects of acupressure (eight treatments over 4 weeks) on cognitive impairment and state of being following TBI, including assessment of event-related potentials (ERPs) during Stroop and auditory oddball tasks. It was hypothesized that active acupressure treatments would confer greater cognitive improvement than placebo treatments, perhaps because of enhanced relaxation response induction and resulting stress reduction. Significant treatment effects were found comparing pre- to post-treatment change between groups. During the Stroop task, the active-treatment group showed greater reduction in both P300 latency (p = 0.010, partial η² = 0.26) and amplitude (p = 0.011, partial η² = 0.26), as well as a reduced Stroop effect on accuracy (p = 0.008, partial η² = 0.21) than did the placebo group. Additionally, the active-treatment group improved more than did the placebo group on the digit span test (p = 0.043, Cohen's d = 0.68). Together, these results suggest an enhancement in working memory function associated with active treatments. Because acupressure emphasizes self-care and can be taught to novice individuals, it warrants further study as an adjunct treatment for TBI.

OBJECT: The primary purpose of this study was to analyze what effect preoperative patient expectations and 36-Item Short Form Health Survey (SF-36) Mental Component Summary (MCS) scores have on clinical outcomes. To the authors' knowledge, there are no prospective studies that have examined the effects of both preoperative pain expectations and SF-36 MCS scores on clinical outcomes and satisfaction with results following anterior cervical discectomy and fusion (ACDF). METHODS: This study analyzed 79 patients (38 men, 41 women) undergoing 1- to 3-level ACDF surgery. Preoperatively, patients were divided into 2 groups for the expectation analyses: patients who expected complete resolution of pain postoperatively (44 total) and those who expected some residual pain (35 total) postoperatively. Preoperative SF-36 MCS scores were used to test the possible effects of mental health on clinical outcomes and satisfaction. Clinical outcomes were evaluated using visual analog scales (VASs) for neck/arm pain, Neck Disability Index (NDI), SF-36 Physical Component Summary (PCS)/MCS, and patient satisfaction with results scales. The mean follow-up duration was 38.8 months (range 7-59 months). RESULTS: All postoperative measures depicted significant improvement overall. Patients who expected no pain reported lower postoperative neck/arm pain scores (p < 0.02), higher SF-36 MCS scores (p = 0.04), and higher satisfaction with results scores (p = 0.01) compared with patients who expected some pain, after controlling for their respective preoperative scores. Higher preoperative SF-36 MCS scores predicted significantly lower postoperative neck pain (p = 0.003) and NDI (p = 0.004) scores, as well as higher postoperative SF-36 PCS (p = 0.002), SF-36 MCS (p = 0.001), and satisfaction (p = 0.03) scores, after controlling for their respective preoperative scores. CONCLUSIONS: Patients who expected no pain postoperatively reported better scores on the nonstandardized outcome measure scales (VAS arm/neck, satisfaction with results), and higher SF-36 MCS scores. Higher preoperative MCS scores were related to better overall (standardized and nonstandardized) clinical outcomes (VAS neck, NDI, SF-36 PCS/MCS, and satisfaction with results). The results suggest that optimism in patients' expectations as well as mental well-being are related to improved clinical outcomes and higher patient satisfaction.

OBJECTIVES: Acupressure, a complementary and alternative medicine (CAM) treatment, uses fingertips, rather than needles, to stimulate acupoints on the skin and has been implicated as a successful treatment for a variety of medical disorders. However, acupressure's underlying mechanisms remain unclear. One theory is that acupoint stimulation modulates autonomic nervous system activity. Previous studies have suggested that acupressure may positively affect heart rate and blood pressure. The current study investigated the effects of a type of acupressure, Jin Shin, on cardiovascular function in stroke survivors, a population that could especially benefit from a treatment promoting cardiovascular health. The study tested the hypothesis that active acupressure treatments would reduce heart rate and blood pressure (i.e., induce a greater relaxation response) above and beyond that seen during placebo acupressure treatments. METHODS: A randomised, placebo-controlled, single-blind crossover design was utilised, in which 16 participants received 8 weeks of either active or placebo acupressure followed by washout and crossover into the opposite treatment condition. Heart rate and blood pressure measurements were taken throughout treatments. RESULTS: Active acupressure treatments were associated with a significantly greater (p=.043, eta(2)=.30) and faster (p=.002, eta(2)=.76) reduction in heart rate compared to that seen during placebo treatments. No treatment effect on blood pressure was found. CONCLUSIONS: Active acupressure reduced heart rate significantly more than did placebo acupressure during treatments. Although no treatment effect on blood pressure was found, this could be due to 67% of participants taking antihypertensive medications during the study.

OBJECTIVE: The aim of this study was to explore how attitudes toward complementary and alternative medicine (CAM) and conventional medicine influence CAM use in a healthy population, and how health locus of control and exercise further affect CAM use. DESIGN: A cross-sectional survey design was used. PARTICIPANTS: The sample consisted of 65 healthy graduate students. MAIN OUTCOME MEASURES: Since previous studies have focused on the attitudes of medical providers toward CAM, there are currently no standard, widely used measures of attitudes toward CAM from the perspective of the healthcare recipient. Thus, a new measure, the Complementary, Alternative, and Conventional Medicine Attitudes Scale (CACMAS) was created to address how attitudes of healthcare recipients affect CAM use. The Multidimensional Health Locus of Control Scale (MHLC) was used to investigate effects of health locus of control on CAM use, and participants reported which of 17 listed CAM treatments they had used in the past, were currently using, or would likely use in the future. Participants also reported days of exercise in the past month to explore if those engaging in healthy behaviors might report more CAM use. RESULTS: Having a philosophical congruence with CAM and agreement with holistic balance was associated with increased CAM use. Dissatisfaction with conventional medicine was also related to increased CAM use, but to a lesser extent. Those attributing health to personal behaviors (an internal health locus of control) reported more CAM use, as did those engaging in more resistance training in the previous month.
