An Exploration of Modifiable Risk Factors for Depression After Spinal Cord Injury: Which Factors Should We Target?

OBJECTIVE To identify modifiable risk factors for depression in people with spinal cord injury (SCI). DESIGN Cross-sectional survey. SETTING Outpatient and community settings. PARTICIPANTS Community-residing people with SCI (N=244; 77% men, 61% white; mean age, 43.1y; 43% with tetraplegia) who were at least 1 month postinjury. INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES Depression severity (Patient Health Questionnaire-9 [PHQ-9]), physical activity (International Physical Activity Questionnaire [IPAQ]), pleasant and rewarding activities (Environment Rewards Observation Scale [EROS]), and self-efficacy to manage the effects of SCI (Modified Lorig Chronic Disease Self-Management Scale). RESULTS Greater depression severity was associated with being 20 to 29 years of age, not completing high school, not working or attending school, and being ≤4 years post-SCI. After controlling for demographic and injury characteristics (adjusted R(2)=.13), lower EROS scores (change in adjusted R(2)=.34) and lower self-efficacy (change in R(2)=.13) were independent predictors of higher PHQ-9 scores. Contrary to predictions, physical activity as measured by the IPAQ did not predict depression severity. CONCLUSIONS Our findings suggest that having fewer rewarding activities, and to a lesser extent, having less confidence in ones ability to manage the effects of SCI are independent predictors of greater depression severity after SCI. Interventions such as behavior activation, designed to increase rewarding activities, may represent an especially promising approach to treating depression in this population.

Perceived injustice after traumatic injury: Associations with pain, psychological distress, and quality of life outcomes 12 months after injury.

OBJECTIVE There is growing recognition that individuals who experience traumatic injuries perceive themselves as victims of injustice and that elevated levels of perceived injustice are associated with problematic physical and psychological outcomes. To date, research regarding injustice perception and injury outcomes has been restricted to a small number of musculoskeletal pain conditions. No research to date has examined the potential impact of perceived injustice among individuals admitted for trauma care. METHOD As part of this cross-sectional study, individuals (n = 155) admitted to a Level-1 trauma center completed measures of perceived injustice, pain, depression, posttraumatic stress, and health related (physical and mental/emotional) quality of life (HRQoL) outcomes 12 months after trauma admission. RESULTS Bivariate analyses revealed significant associations between perceived injustice and demographic variables (education, income, race, and age) as well as injury-related variables (type of injury and length of hospital stay). Perceived injustice was correlated with greater pain intensity, depression, and PTSD symptoms, as well as poorer physical and mental HRQoL. Controlling for relevant demographic and injury-related variables, perceived injustice accounted for unique variance in pain intensity, depression severity, the presence and intensity of PTSD symptoms, mental HRQoL, and was marginally significant for physical HRQoL. CONCLUSIONS This is the first study to examine perceived injustice in a trauma sample. Results support the presence of injustice perception in this group and its associations with pain and quality of life outcomes. Additional research is suggested to explore the impact of perceived injustice on recovery outcomes among individuals who have sustained traumatic injury.

Resilience following spinal cord injury: a phenomenological view

Study design:Qualitative research design involving semi-structured focus groups.Objectives:To increase current understanding of how persons with spinal cord injuries (SCI) define resilience and what factors contribute to their resilience or the resilience of others.Setting:Inpatient rehabilitation program in a large urban city in the Southwestern United States.Methods:A convenience sample of 28 participants (14 current patients; 14 former patients) participated in semi-structured focus groups led by the research investigators.Results:Through a constant comparative analysis of the data, six themes emerged in participants’ responses regarding what they believed contributed to their own resilience in adapting to SCI. The six themes included psychological strength, social support, perspective, adaptive coping, spirituality or faith, and serving as a role model or inspiring others.Conclusion:Consistent with previous research findings, individuals with SCI identified positive thinking (for example, optimism, hope and positive attitude), perseverance and determination, and social support from friends and family as important contributors to their ability to adapt in spite of experiencing traumatic events that resulted in SCI. Findings provide richness and depth to current empirical conceptualizations of resilience.

Living Donor Uterus Transplantation: A Single Center's Observations and Lessons Learned From Early Setbacks to Technical Success

Uterus transplantation is a vascularized composite allograft transplantation. It allows women who do not have a uterus to become pregnant and deliver a baby. In this paper, we analyze the first five cases of living donor uterus transplantation performed in the United States. The first three recipients lost their uterus grafts at days 14, 12, and 6, respectively, after transplant. Vascular complications, related to both inflow and outflow problems, were identified as the primary reason for the graft losses. Two recipients, at 6 and 3 mo, respectively, after transplant, have functioning grafts with regular menstrual cycles. Ultimate success will be claimed only after a live birth. This paper is an in‐depth analysis of evaluation, surgical technique, and follow‐up of these five living donor uterus transplants. The lessons learned were instrumental in allowing us to evolve from failure to technical and functional success. We aim to share our conclusions and build on knowledge in the evolving field of uterus transplantation.

Venlafaxine extended-release for depression following spinal cord injury a randomized clinical trial

IMPORTANCE Depression is prevalent and associated with negative outcomes in individuals with spinal cord injury (SCI). Antidepressants are used routinely to treat depression, yet no placebo-controlled trials have been published in this population to our knowledge. OBJECTIVE To determine the efficacy and tolerability of venlafaxine hydrochloride extended-release (XR) for major depressive disorder (MDD) or dysthymic disorder in persons with chronic SCI. DESIGN, SETTING, AND PARTICIPANTS Multisite, randomized (1:1), double-blind, placebo-controlled Project to Improve Symptoms and Mood After SCI (PRISMS) trial. All research staff conducting screening, intervention, and outcome procedures were blinded to randomization status. We screened 2536 patients from outpatient clinics at 6 SCI treatment centers in the United States and randomized 133 participants into the trial. Participants were 18 to 64 years old and at least 1 month after SCI, with MDD or dysthymic disorder. Seventy-four percent of participants were male, and participants were on average 40 years old and 11 years after SCI. Forty-seven percent had cervical injuries, 53.4% had American Spinal Injury Association injury severity A (complete injury) SCI, 24.1% had at least 2 prior MDD episodes, and 99.2% had current MDD. Common comorbidities included chronic pain (93.9%), significant anxiety (57.1%), and history of substance dependence (44.4%). INTERVENTIONS Twelve-week trial of venlafaxine XR vs placebo using a flexible-dose algorithm. MAIN OUTCOMES AND MEASURES The Hamilton Depression Rating Scale (HAM-D 17-item version and Maier subscale, which focuses on core depression symptoms and excludes somatic symptoms) over 12 weeks. RESULTS Mixed-effects models revealed a significant difference between the venlafaxine XR and placebo groups in improvement on the Maier subscale from baseline to 12 weeks (treatment effect, 1.6; 95% CI, 0.3-2.9; P = .02) but not on the HAM-D 17-item version (treatment effect, 1.0; 95% CI, -1.4 to 3.4; P = .42). Participants receiving venlafaxine XR reported significantly less SCI-related disability on the Sheehan Disability Scale at 12 weeks compared with placebo (treatment effect, 4.7; 95% CI, 1.5-7.8; P = .005). Blurred vision was the only significantly more common new or worsening adverse effect in the venlafaxine XR group compared with the placebo group over 12 weeks. CONCLUSIONS AND RELEVANCE Venlafaxine XR was well tolerated by most patients and an effective antidepressant for decreasing core symptoms of depression and improving SCI-related disability. Further research is needed to determine the optimal treatment and measurement approaches for depression in chronic SCI. TRIAL REGISTRATION clinicaltrials.gov Identifier: NCT00592384.

Posttraumatic stress disorder following traumatic injury at 6 months: associations with alcohol use and depression.

BACKGROUND Posttraumatic stress disorder (PTSD) is progressively recognized as a psychological morbidity in injured patients. Participants in a longitudinal study were identified as PTSD positive or PTSD negative at 6 months following injury. Risky alcohol use, depression, demographic, and injury-related variables were explored. METHODS This prospective cohort included patients 18 years or older, admitted to our Level I trauma center. Outcome measures included PTSD Checklist—Civilian Version (PCL-C), Alcohol Use Disorders Identification Test (AUDIT-C), and Patient Health Questionnaire (PHQ-8). Demographic and injury variables were collected. RESULTS A total of 211 participants enrolled in the study, and 118 participants completed measures at both baseline and 6 months. Of the participants, 25.4% (n = 30) screened positive for PTSD at 6 months. The entire sample showed a decline in risky alcohol use at 6 months (p = 0.0043). All PTSD-positive participants at 6 months were also positive for depression (p < 0.0001). For the entire sample, there was a 10% increase in depression from baseline to 6 months (p = 0.03). However, for those participants who were PTSD positive at 6 months, there was a 53% increase in depression from baseline (p = 0.0002) as compared with the group at 6 months without PTSD. Statistically significant differences were found between PTSD-positive and PTSD-negative participants regarding age (40.1 [15.9] vs. 50.9 [18.2], p = 0.0047), male (77% vs. 50%, p = 0.0109), penetrating injury (30% vs. 4%, p < 0.0001), PTSD history (17% vs. 4%, p = 0.0246), or other psychiatric condition (63% vs. 19%, p ⩽ 0.001). CONCLUSION PTSD was not associated with risky alcohol use at 6 months. Surprisingly, risky alcohol use declined in both groups. Incidence of PTSD (25.4%, n = 30) and risky alcohol use (25%, n = 29) were equal at 6 months. Although the American College of Surgeons’ Committee on Trauma requires brief screening and intervention for risky alcohol use owing to societal impact, reinjury rates, and cost effectiveness, our study suggests that screening for psychological conditions may be equally important.

Psychological factors predicting outcome after traumatic injury: the role of resilience.

BACKGROUND Increasingly, studies have examined the psychological impact on individuals who survive a traumatic physical injury. The primary aim of this study was to determine the stability of resilience and its association with depressive symptoms. METHODS This study included 110 adults admitted to a Level I trauma center. Resilience and depression were measured at baseline and 12 months. Injury-related variables included Glasgow Coma Scale, Injury Severity Score, etiology of injury, and type of injury. RESULTS Analysis revealed that resilience remained stable over 12 months regardless of injury severity, etiology, or type. Negative correlations were found between baseline resilience and 12-month depression (P < .01), as well as Glasgow Coma Scale and depression (P = .001). CONCLUSIONS Injured individuals with low resilience are more likely to be depressed at 12 months. Assessing resilience at the time of injury may be useful in identifying those at risk for depression 1 year later.

Predictors of PTSD symptoms in adults admitted to a Level I trauma center: a prospective analysis

Trauma centers are an ideal point of intervention in efforts to prevent posttraumatic stress disorder (PTSD). In order to assist in the development of prevention efforts, this study sought to identify early predictors of PTSD symptoms among adults admitted to a Level I trauma center using a novel analytic strategy (Fournier et al., 2009). Upon admission, participants (N=327) were screened for PTSD symptoms and provided information on potential predictor variables. Their PTSD symptoms were assessed again 3 months later (N=227). Participants were classified as symptomatic (positive PTSD screen) or asymptomatic (negative PTSD screen) at the follow-up assessment. Multinomial logistic regression showed that age, depression, number of premorbid psychiatric disorders, gunshot wound, auto vs. pedestrian injury, and alcohol use predicted who had PTSD symptoms at FU with 76.3% accuracy. However, when controlling for PTSD severity at baseline, only age, number of premorbid psychiatric disorders, and gunshot wounds predicted PTSD symptoms at FU but with 78.5% accuracy. These findings suggest that psychological prevention efforts in trauma centers may be best directed toward adults who are young, have premorbid psychiatric disorders, and those admitted with gunshot wounds.

Mild traumatic brain injury increases risk for the development of posttraumatic stress disorder.

BACKGROUND Traumatic brain injury (TBI) and posttraumatic stress disorder (PTSD) occur in individuals who sustain physical injury and share a significant overlap in symptoms. PTSD rates in the civilian injury population range from 20% to 40%. The current study examined the presence of PTSD symptoms at multiple time points (3 months and 6 months after injury) among individuals with and without TBI after admission to a Level I trauma center. METHODS This prospective cohort study included patients 18 years and older admitted to a Level I trauma center for 24 hours or greater. Demographic and injury-related data were gathered in addition to assessments of PTSD during initial hospitalization after injury, as well as 3 months and 6 months later. The Primary Care PTSD Screen and PTSD Checklist–Civilian version were used to determine probable PTSD. International Classification of Diseases, 9th Rev. codes were used to determine mild TBI (MTBI). RESULTS A total of 494 patients were enrolled at baseline, 311 (63%) completed 3-month follow-up, and 231 (47%) completed 6-month follow-up at the time of analysis. Preinjury PTSD was reported by 7% of the participants. At 3 months, patients with MTBI evidenced a probable PTSD rate of 18%, compared with a rate of 9% for patients with no MTBI (p = 0.04), although this relationship became a nonsignificant trend (p = 0.06) when demographics were included. At 6 months, patients with MTBI evidenced a probable PTSD rate of 26%, compared with a rate of 15% for patients with no MTBI (p = 0.04), and this relationship remained significant when demographics were included. Preinjury history of TBI did not predict PTSD, but incidence of TBI for the injury in which they were hospitalized did predict PTSD. CONCLUSION TBI at time of injury demonstrated a nonsignificant trend toward higher rates of PTSD at 3 months and significantly predicted PTSD at 6 months after injury. This important finding may help clinicians identify patients at high risk for PTSD after injury and target these patients for screening, intervention, and referral for treatment. LEVEL OF EVIDENCE Prognostic study, level III.

A randomized controlled trial of venlafaxine XR for major depressive disorder after spinal cord injury: Methods and lessons learned

Abstract Context/objective We describe the rationale, design, methods, and lessons learned conducting a treatment trial for major depressive disorder (MDD) or dysthymia in people with spinal cord injury (SCI). Design A multi-site, double-blind, randomized (1:1) placebo controlled trial of venlafaxine XR for MDD or dysthymia. Subjects were block randomized and stratified by site, lifetime history of substance dependence, and prior history of MDD. Setting Six SCI centers throughout the United States. Participants Across participating centers, 2536 subjects were screened and 133 were enrolled into the trial. Subjects were 18–64 years old and at least 1 month post-SCI. Interventions Twelve-week trial of venlafaxine XR versus placebo using a flexible titration schedule. Outcome measures The primary outcome was improvement in depression severity at 12 weeks. The secondary outcome was improvement in pain. Results This article includes study methods, modifications prompted by a formative review process, preliminary data on the study sample and lessons learned. We describe common methodological and operational challenges conducting multi-site trials and how we addressed them. Challenges included study organization and decision making, staff training, obtaining human subjects approval, standardization of measurement and treatment, data and safety monitoring, subject screening and recruitment, unblinding and continuity of care, database management, and data analysis. Conclusions The methodological and operational challenges we faced and the lessons we learned may provide useful information for researchers who aim to conduct clinical trials, especially in the area of medical treatment of depression in people with SCI.
