Introduction: Black and Latino individuals are underrepresented in COVID-19 treatment and vaccine clinical trials, calling for an examination of factors that may predict willingness to participate in trials., Methods: We administered the Common Survey 2.0 developed by the Community Engagement Alliance (CEAL) Against COVID-19 Disparities to 600 Black and Latino adults in Baltimore City, Prince George's County, Maryland, Montgomery County, Maryland, and Washington, DC, between October and December 2021. We examined the relationship between awareness of clinical trials, social determinants of health challenges, trust in COVID-19 clinical trial information sources, and willingness to participate in COVID-19 treatment and vaccine trials using multinomial regression analysis., Results: Approximately half of Black and Latino respondents were unwilling to participate in COVID-19 treatment or vaccine clinical trials. Results showed that increased trust in COVID-19 clinical trial information sources and trial awareness were associated with greater willingness to participate in COVID-19 treatment and vaccine trials among Black and Latino individuals. For Latino respondents, having recently experienced more challenges related to social determinants of health was associated with a decreased likelihood of willingness to participate in COVID-19 vaccine trials., Conclusions: The willingness of Black and Latino adults to participate in COVID-19 treatment and vaccine clinical trials is influenced by trial awareness and trust in trial information sources. Ensuring the inclusion of these communities in clinical trials will require approaches that build greater awareness and trust., Competing Interests: The authors declare none., (© The Author(s) 2024.)

Background: Patients admitted to hospitals after emergency care for injury or acute illness are at risk for later mental health problems. The American College of Surgeons Committee on Trauma Standards for care of injured patients call for mental health risk screening, and the Hospital Mental Health Risk Screen (HMHRS) accurately identified at-risk patients in a developmental study that included patients from five ethnoracial groups. Replication of these findings is essential, because initial positive results for predictive screens can fail to replicate if the items were strongly related to outcomes in the development sample but not in a new sample from the population the screen was intended for., Study Design: Replication of the predictive performance of the 10-item HMHRS was studied prospectively in ethnoracially diverse patients admitted after emergency care for acute illness or injury in three hospitals across the U.S., Results: Risk screen scores and follow-up mental health outcomes were obtained for 452 of 631 patients enrolled (72%). A cut score of 10 on the HMHRS correctly identified 79% of the patients who reported elevated levels of depression, anxiety, and PTSD symptoms two months post-admission (sensitivity) and 72% of the patients whose symptoms were not elevated (specificity). HMHRS scores also predicted well for patients with acute illness, for patients with injuries, and for patients who reported an Asian American/Pacific Islander, Black, Latinx, Multirace, or White identity., Conclusions: Predictive performance of the HMHRS was strong overall and within all five ethnoracial subgroups. Routine screening could reduce suffering and health care costs, increase health and mental health equity, and foster preventive care research and implementation. The performance of the HMHRS should be studied in other countries and in other populations of recent trauma survivors, such as survivors of disaster or mass violence., Competing Interests: The authors have declared that no competing interests exist., (Copyright: This is an open access article, free of all copyright, and may be freely reproduced, distributed, transmitted, modified, built upon, or otherwise used by anyone for any lawful purpose.

Background: High rates of mental health symptoms such as depression, anxiety, and posttraumatic stress disorder (PTSD) have been found in patients hospitalized with traumatic injuries, but little is known about these problems in patients hospitalized with acute illnesses. A similarly high prevalence of mental health problems in patients hospitalized with acute illness would have significant public health implications because acute illness and injury are both common, and mental health problems of depression, anxiety, and PTSD are highly debilitating., Methods and Findings: In patients admitted after emergency care for Acute Illness (N = 656) or Injury (N = 661) to three hospitals across the United States, symptoms of depression, anxiety, and posttraumatic stress were compared acutely (Acute Stress Disorder) and two months post-admission (PTSD). Patients were ethnically/racially diverse and 54% female. No differences were found between the Acute Illness and Injury groups in levels of any symptoms acutely or two months post-admission. At two months post-admission, at least one symptom type was elevated for 37% of the Acute Illness group and 39% of the Injury group. Within racial/ethnic groups, PTSD symptoms were higher in Black patients with injuries than for Black patients with acute illness. A disproportionate number of Black patients had been assaulted., Conclusions: This study found comparable levels of mental health sequelae in patients hospitalized after emergency care for acute illness as in patients hospitalized after emergency care for injury. Findings of significantly higher symptoms and interpersonal violence injuries in Black patients with injury suggest that there may be important and actionable differences in mental health sequelae across ethnic/racial identities and/or mechanisms of injury or illness. Routine screening for mental health risk for all patients admitted after emergency care could foster preventive care and reduce ethnic/racial disparities in mental health responses to acute illness or injury., Competing Interests: The authors have declared that no competing interests exist., (Copyright: This is an open access article, free of all copyright, and may be freely reproduced, distributed, transmitted, modified, built upon, or otherwise used by anyone for any lawful purpose.

Introduction: Poor sleep is common in our society, particularly for African Americans, and is associated with adverse mental and physical health outcomes. Unwanted, intrusive thoughts contribute to sleep disturbances and can be engendered by living in stressful urban environments, which are disproportionately inhabited by African Americans. Studies of other populations have shown that cognitive coping strategies to manage intrusive thoughts vary in their adaptiveness., Objective: To examine the relationship between thought control strategies and insomnia severity in urban residing young-adult African Americans., Method: Sixty-four young adult African Americans completed a demographic questionnaire, the Thought Control Questionnaire for Insomnia-revised, and the Insomnia Severity Index., Results: There were moderate to strong positive correlations of aggressive suppression, worry, behavioral distraction, and social avoidance with ISI scores. Poor sleepers endorsed greater use of worry and aggressive suppression than good sleepers. Results from a multiple linear regression analysis revealed that aggressive suppression, social avoidance, and behavioral distraction significantly predicted insomnia severity, and aggressive suppression was the strongest predictor in the model., Conclusions: These results extend findings of aggressive suppression as a correlate of insomnia severity to an urban-residing young adult African American sample. Future research should identify adaptive approaches and the utility of modifying maladaptive strategies.

Background: Chronic insufficient sleep is linked to a variety of adverse health outcomes, and African Americans have been found to have poorer sleep than their non-Hispanic White counterparts. African Americans disproportionately live in low-income disordered neighborhoods which increases their risk of trauma exposure and adversely affects their sleep. Fear of sleep is a construct linked to posttraumatic stress disorder (PTSD). We have reported a relationship between fear of sleep and insomnia in urban residing African Americans. Our objective is to report the relative contributions of neighborhood stress along with PTSD to fear of sleep., Methods: The present study features a nonclinical sample of 117 African Americans (ages 18-35) who reside in DC., Results: After controlling for gender, hierarchical linear regression analyses revealed that PTSD severity and perceptions of the neighborhood environment accounted for approximately 32% of the variance in sleep-related fears (∆R2 = .320, p < .001). Regression coefficients suggest that perceptions of the neighborhood (β = .360) predict sleep-related fears to a similar degree as PTSD severity (β = .368)., Conclusion: Results from this study have implications for interventions to help African Americans to cope with their neighborhood environments effect on their sleep.

Study Objectives: Self-reported sleep disturbance has been established as a risk factor and predictor for posttraumatic stress disorder (PTSD); however, less is known about the relationship between objective sleep and PTSD symptom clusters, and the specific role of hyperarousal. The present study examined the relationships between sleep continuity and architecture on PTSD symptom clusters., Methods: Participants underwent two in-laboratory sleep studies to assess sleep continuity and architecture. They also completed the Clinician-Administered PTSD-IV scale and the Structured Clinical Interview for the DSM-IV to assess for PTSD diagnosis and other psychiatric disorders., Results: Sleep continuity (i.e. total sleep time, sleep efficiency percent, wake after sleep onset, sleep latency) was significantly related to PTSD Cluster B (reexperiencing) symptom severity ( R 2 = .27, p < .001). Sleep architecture, specifically Stage N1 sleep, was significantly associated with PTSD Cluster B ( t = 2.98, p = .004), C (Avoidance; t = 3.11, p = .003), and D (Hyperarosual; t = 3.79, p < .001) symptom severity independently of Stages N2, N3, and REM sleep. REM sleep variables (i.e. REM latency, number of REM periods) significantly predicted Cluster D symptoms ( R 2 = .17, p = .002)., Conclusions: These data provide evidence for a relationship between objective sleep and PTSD clusters, showing that processes active during Stage N1 sleep may contribute to PTSD symptomatology in civilians and veterans. Further, these data suggest that arousal mechanisms active during REM sleep may also contribute to PTSD hyperarousal symptoms.This paper is part of the War, Trauma, and Sleep Across the Lifespan Collection.

Study Objectives: Effective pharmacological treatments for sleep disturbance related to trauma with and without co-occurring posttraumatic stress disorder (PTSD) are needed. There is debate regarding what effects on rapid eye movement sleep (REMS) would be beneficial. Suvorexant is the first dual orexin receptor antagonist (DORA) approved for the treatment of insomnia. In contrast to most psychotropic agents, DORAs can enhance REMS while reducing arousal. We evaluated 6 weeks of suvorexant treatment for trauma-related insomnia in a double-blind, placebo-controlled clinical trial with clinical and polysomnographic evaluation., Methods: Participants with insomnia that followed a traumatic event were recruited from the community. Representation of current, past-only, and never having met criteria for PTSD was similar and most participants had experienced trauma-related nightmares. Participants were randomly assigned to receive suvorexant or placebo, initially at 10 mg and increased to 20 mg after 1 week, if tolerated. Polysomnography was obtained for screening, at baseline, and at 2 weeks of treatment., Results: The thirty-seven evaluable participants had significant improvement of PTSD and insomnia symptoms, however, there were no significant interactions with treatment condition. Medication was well tolerated with only one dropout being related to side effects. Within the suvorexant group increased REM segment duration correlated with concurrent PTSD symptom reduction. Nightmares remitted in all of the participants who received suvorexant and all but one of those receiving placebo., Conclusions: A robust placebo response undermined detecting a medication effect. Further evaluation of DORAs for trauma-related insomnia, as well as factors contributing to placebo-response, are warranted., (© The Author(s) 2022.

Objectives: This study was undertaken to evaluate the diagnostic performance of the BinaxNOW COVID-19 Ag Card rapid antigen assay (Abbott; Chicago, IL, USA) in the detection of COVID-19 infection compared to the reference standard of PCR testing., Methods: We evaluated the BinaxNOW COVID-19 Ag Card rapid antigen assay relative to a standard reference PCR test. We tested 3810 nasal swabs from symptomatic and asymptomatic adults undergoing surveillance COVID-19 testing at Howard University using one swab for each nostril. One swab was tested using the rapid antigen assay and the other using the PCR test., Results: The sensitivity of the BinaxNOW COVID-19 Ag Card rapid antigen assay was 91.84% (95% confidence interval (CI): 80.40-97.73%) and the specificity was 99.95% (95% CI: 99.81-99.99%). The range of Ct values for the N gene was 10.74-34.90 (M = 26.88, SD=4.86). Fourteen (28.6%) samples had an N gene Ct value > 30. The average N gene Ct value for rapid test negative (i.e. false negative) samples was 31.92., Conclusions: The sensitivity of the test in our symptomatic and asymptomatic cohort was lower than the manufacturer's reported sensitivity in a symptomatic cohort (97.1%). Despite their relatively lower sensitivity (especially in asymptomatic individuals), rapid tests have undeniable benefits (i.e., ease of use and rapid results) that make them a helpful tool in the control of the SARS-CoV-2 pandemic. Given the diagnostic accuracy of these tests as evidenced by this study, rapid tests can be thoughtfully employed in situations where swift results are critical., (Copyright © 2021.

There is a need to identify strategies to increase the effectiveness of treatments for posttraumatic stress disorder (PTSD). Sleep is often disturbed in PTSD and has been implicated in learning processes that underlie recovery from PTSD, including extinction of conditioned fear. Our prior study suggested that diminished arousal during sleep may enhance benefits of therapeutic exposure for PTSD. The orexin system regulates arousal, and blocking the system diminishes arousal and promotes sleep. We, therefore, examined whether a dual orexin receptor antagonist, suvorexant, administered following evening exposure sessions, would enhance their therapeutic effectiveness for PTSD. In this randomized double-blind placebo-controlled trial, adults with PTSD completed four written narrative exposure (WNE) sessions, two of which took place in the evening, and two the next morning. Participants received either suvorexant or placebo after each evening WNE. We found that suvorexant increased N3 sleep and decreased N2 sleep and rapid-eye-movement latency measured by polysomnography. Between session habituation indexed by subjective distress ratings was greater with suvorexant, but there was no group difference in the reduction of PTSD severity from baseline to 1-week follow-up. No safety concerns emerged. The present findings provide preliminary support for enhancement of an effect of therapeutic exposure for PTSD by suvorexant. Further studies with larger samples are needed to translate the present findings into clinical applications, including studies to develop optimal suvorexant administration and exposure session schedules to achieve persistent benefits to sleep and possibly greater treatment augmentation., (Copyright © 2021 Elsevier Ltd.

Background: Heightened autonomic nervous system (ANS) arousal is a well-established contributor to the effect of stress on adverse cardiovascular health outcomes which disproportionately affect African Americans. ANS arousal is normally attenuated during sleep and compromise of this shift is associated with multiple adverse cardiovascular outcomes. Parasympathetic nervous system (PNS) dominance during sleep can be altered by stress. Racism has been recognized to have many negative health consequences in African Americans. Perceived racism has been linked to ANS activity, however, we are not aware of prior research on racism and nocturnal ANS balance., Objective: To examine relationships between perceived racism and nocturnal ANS activity indexed by heart rate variability (HRV) in healthy African American men and women age 18-35., Methods: Fifty-four participants completed the Perceived Racism Scale and had 24-hour ambulatory electrocardiogram recordings in their homes. Power spectral analysis was used to derive normalized high frequency (nHF) to index PNS activity which was computed by 5-minute epochs during wake and sleep., Results: Endorsement of racism and negative emotional reactions during the past year were inversely related to nHF during time in bed. Multiple regression analysis indicated that negative emotional reactions were a significant predictor of nHF during the sleep period F(2,54) = 4.213, p = .020, R 2  = 0.135 (adjusted R 2  = 0.103). Relationships during wake were not statistically significant., Conclusion: Findings suggest that perseverative thoughts triggered by negative emotional reactions to racism influencing nocturnal ANS activity may be a pathway by which perceived racism affects health.

Study Objectives: Stressful neighborhood environments are known to adversely affect health and contribute to health disparities but underlying mechanisms are not well understood. Healthy sleep can provide a respite from sustained sympathetic nervous system (SNS) activity. Our objective was to evaluate relationships between neighborhood stress and nocturnal and daytime SNS and parasympathetic nervous system (PNS) activity., Methods: Eighty-five urban-residing African Americans (56.5% female; mean age of 23.0) participated. Evaluation included surveys of neighborhood stress and sleep-related vigilance, and continuous electrocardiogram (ECG) and actigraphic recording in participants' homes from which heart rate variability (HRV) analysis for low frequency/high frequency (LF/HF) ratio and normalized high frequency (nHF), as indicators of SNS and PNS activity, respectively, and total sleep time (TST), and wake after sleep onset were derived., Results: All significant relationships with HRV measures were from the sleep period. Neighborhood disorder correlated negatively with nHF (r = -.24, p = .035). There were also significant correlations of HRV indices with sleep duration and sleep fears. Among females, LF/HF correlated with exposure to violence, r = .39, p = .008, and nHF with census tract rates for violent crime (r = -.35, p = .035). In a stepwise regression, TST accounted for the variance contributed by violent crime to nHF in the female participants., Conclusions: Further investigation of relationships between neighborhood environments and SNS/PNS balance during sleep and their consequences, and strategies for mitigating such effects would have implications for health disparities.

Background: In randomized trials, prazosin, an α 1 -adrenoreceptor antagonist, has been effective in alleviating nightmares associated with post-traumatic stress disorder (PTSD) in military veterans., Methods: We recruited veterans from 13 Department of Veterans Affairs medical centers who had chronic PTSD and reported frequent nightmares. Participants were randomly assigned to receive prazosin or placebo for 26 weeks; the drug or placebo was administered in escalating divided doses over the course of 5 weeks to a daily maximum of 20 mg in men and 12 mg in women. After week 10, participants continued to receive prazosin or placebo in a double-blind fashion for an additional 16 weeks. The three primary outcome measures were the change in score from baseline to 10 weeks on the Clinician-Administered PTSD Scale (CAPS) item B2 ("recurrent distressing dreams"; scores range from 0 to 8, with higher scores indicating more frequent and more distressing dreams); the change in score from baseline to 10 weeks on the Pittsburgh Sleep Quality Index (PSQI; scores range from 0 to 21, with higher scores indicating worse sleep quality); and the Clinical Global Impression of Change (CGIC) score at 10 weeks (scores range from 1 to 7, with lower scores indicating greater improvement and a score of 4 indicating no change)., Results: A total of 304 participants underwent randomization; 152 were assigned to prazosin, and 152 to placebo. At 10 weeks, there were no significant differences between the prazosin group and the placebo group in the mean change from baseline in the CAPS item B2 score (between-group difference, 0.2; 95% confidence interval [CI], -0.3 to 0.8; P=0.38), in the mean change in PSQI score (between-group difference, 0.1; 95% CI, -0.9 to 1.1; P=0.80), or in the CGIC score (between-group difference, 0; 95% CI, -0.3 to 0.3; P=0.96). There were no significant differences in these measures at 26 weeks (a secondary outcome) or in other secondary outcomes. At 10 weeks, the mean difference between the prazosin group and the placebo group in the change from baseline in supine systolic blood pressure was a decrease of 6.7 mm Hg. The adverse event of new or worsening suicidal ideation occurred in 8% of the participants assigned to prazosin versus 15% of those assigned to placebo., Conclusions: In this trial involving military veterans who had chronic PTSD, prazosin did not alleviate distressing dreams or improve sleep quality.

Compromised sleep and increased sympathetic nervous system (SNS) activity are implicated in the pathogenesis of, and disparities in, cardiovascular disease. Parasympathetic dominance during sleep may be important for cardiovascular health. Sleep and autonomic balance influence immune activity, which impacts atherogenesis. We evaluated relationships between autonomic balance during sleep and morning levels of the immune activating cytokines, C-reactive protein (CRP) and interleukin (IL)-6. Ninety-four (59 female) young adult African Americans without medical conditions and substance use disorders spent 2 consecutive nights in a clinical research unit for sleep recordings and blood drawing on awakening. Cardiac tracings from the second sleep recording were analysed for heart rate variability (HRV). Body mass index was the only non-HRV measure correlated with cytokine levels. Indicators of SNS activity for the presleep, and first non-rapid eye movement (REM) and REM sleep periods were correlated independently with morning IL-6 levels. Altered autonomic balance during sleep may be a modifiable factor that influences immune activation., (© 2017 European Sleep Research Society.)

This study's objective was to investigate the relationship between a variable-number tandem-repeat (VNTR) Period 3 gene (PER3) polymorphism and sleep adaptation to stressful urban environments. Seventy-five (49 female) African American participants (ages 18-35 years) living in neighbourhoods with high rates of violent crime were selected for the study based on converging criteria for good or poor sleep. Categorization of sleep quality was based on the Insomnia Severity Index (ISI), estimates of typical sleep duration and sleep efficiency. Other assessments included the Fear of Sleep Index (FOSI) and City Stress Inventory (CSI). Whole blood DNA was analysed for the 4 and 5 VNTR alleles using polymerase chain reaction (PCR) and restrictive enzyme digestion. Fifty-seven per cent of those who were homo- or heterozygous for the 4-repeat allele were poor sleepers versus 25% of those homozygous for the 5-repeat allele; χ 2  = 4.17, P = 0.041. In a logistic regression model with all the variables with significant bivariate relationships to sleep quality group, FOSI was the only significant predictor (χ 2  = 5.68, P = 0.017). FOSI scores were higher among those with the 4-repeat allele (t = 2.66, P = 0.013). The PER3 4 and 5 VNTR polymorphisms appear to influence sensitivity to the effects of stressful urban environments on sleep. While FOSI was the only variable associated independently with sleep quality category, the candidate vulnerability allele was also associated with greater 'fear of sleep'., (© 2016 European Sleep Research Society.)

Sleep has been implicated in learning processes that appear to underlie recovery from posttraumatic stress disorder (PTSD). The importance of quality and timing of sleep following exposure-based therapies has been suggested. The present study evaluated relationships between sleep and adaptive emotional processing following written narrative exposure (WNE) to memories of traumatic events experienced by participants with clinically significant PTSD symptoms. Participants included 21 urban-residing nontreatment-seeking adults with full or subthreshold symptoms of PTSD who completed 4 sessions of 30-min WNE with the first session either in the evening or the morning. There was a significant reduction of PTSD symptom severity after WNE sessions (partial η = .65), but there was no interaction between group assignment based on the initial session's proximity to sleep and initial reduction of PTSD symptom severity (partial η = .01). Polysomnography following evening WNE revealed increased duration of total sleep and N2%, reduced N3%, and increased eye movement density during REM sleep compared with baseline recordings (dz = 0.65 to 1.15). Reduced N3% and increased REM density were associated with less improvement of PTSD symptoms (r = .58 & -.63). These findings suggest a relationship between preservation of diminished arousal during sleep and adaptive trauma memory processing., (Copyright © 2016 International Society for Traumatic Stress Studies.)

Post-traumatic stress disorder (PTSD) is a common and potentially disabling disorder that develops in 1/5 to 1/3 of people exposed to severe trauma. Twin studies indicate that genetic factors account for at least one third of the variance in the risk for developing PTSD, however, the specific role for genetic factors in the pathogenesis of PTSD is not well understood. We studied genome-wide gene expression and DNA methylation profiles in 12 participants with PTSD and 12 participants who were resilient to similar severity trauma exposure. Close to 4000 genes were differentially expressed with adjusted p<0.05, fold-change >2, with all but 3 upregulated with PTSD. Eight odorant/olfactory receptor related genes were up-regulated with PTSD as well as genes related to immune activation, the Gamma-Aminobutyric Acid A (GABAA) receptor, and vitamin D synthesis. No differences with adjusted significance for DNA methylation were found. We conclude that increased gene expression may play an important role in PTSD and this expression may not be a consequence of DNA methylation. The role of odorant receptor expression warrants independent replication., (Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.)

Posttraumatic stress disorder (PTSD) has been associated with sleep disturbances including alterations in sleep stages and recently, elevated nocturnal autonomic nervous system (ANS) arousal (i.e., dominance of the sympathetic nervous system over the parasympathetic nervous system). Data suggest that sleep contributes to the regulation of ANS activity. In our previous ambulatory heart rate variability (HRV) monitoring study, strong relationships between sleep and nocturnal ANS activity in resilient participants (i.e., individuals who had never had PTSD despite exposure to high-impact trauma) were not seen with PTSD. In this study, we examined the impact of PTSD vs. resilience on ANS activity as a function of sleep stage and time of sleep. Participants (age 18-35) with current PTSD (n=38) and resilience (n=33) completed two overnight polysomnography recordings in a lab setting. The second night electrocardiogram was analyzed for frequency domain HRV parameters and heart rate within rapid-eye-movement (REM) and non-REM (NREM) sleep periods. Results indicated that ANS arousal indexed by HRV was greater during REM compared with NREM sleep and that the REM-NREM difference was greater in the PTSD than in the resilient participants. This effect of PTSD was reduced to non-significance when analyses controlled for REM sleep percentage, which was lower with PTSD. Exploratory analyses revealed that the REM-NREM difference in HRV was correlated with REM sleep percentage in resilient participants, but not with PTSD. In contrast with our data from home settings, the present study did not find increased overall nocturnal ANS arousal with PTSD. Analyses did reveal higher heart rate during initial NREM sleep with more rapid decline over the course of NREM sleep with PTSD compared with resilience. Findings suggest that elevated ANS arousal indexed by heart rate with PTSD is specific to the early part of sleep and possible impairment in regulating ANS activity with PTSD related to REM sleep., (Copyright © 2016 Elsevier Inc.

Sleep-disordered breathing (SDB) is reported in up to 69% of adolescents and children with sickle cell disease (SCD) [1], but data regarding the prevalence of SDB in adults with SCD are limited. In order to obtain a preliminary assessment of the frequency and degree of sleep-related hypoxemia and potential associations with cardiovascular function in adults with SCD, we conducted overnight sleep studies, 6-min walk tests, echocardiograms, and hematologic and chemistry panels, calculated the Pittsburgh sleep quality index (PSQI), and conducted fatigue- and health-related quality-of-life measurement in 20 young adults with SCD visiting a sickle cell clinic for routine care. Sleep apnea, defined as an apnea-hypopnea index (AHI) > 5 events/h, was found in 50% of patients. Traditional clinical indicators, such as obesity, the presence of snoring, and reported sleep complaints, did not reliably differentiate them. The patients with AHI > 5 had higher mean systolic blood pressure (p = 0.03), evidence of impaired left ventricular diastolic function (i.e., increased mitral valve E/A ratio, p = 0.05), a trend toward higher reduction in 6-min walk distances (p = 0.06), and lower health-related quality-of-life scores (p ≤ 0.01). Three of nine patients with more severe anemia (total Hb < 9.0) showed nocturnal hypoxemia in the absence of sleep apnea. As prolonged and frequent hypoxemic episodes likely increase risks for vaso-occlusive, cardiovascular, and neurologic complications of SCD, these results suggest that the prevalence and severity of SDB should be investigated further in studies of larger patient populations. If confirmed, these findings could identify opportunities to prevent or reduce nocturnal hypoxia and improve outcomes., (Copyright © 2016 Elsevier B.V. All rights reserved.)

Stress- and anxiety-related disorders are on the rise in both military and general populations. Over the next decade, it is predicted that treatment of these conditions, in particular, posttraumatic stress disorder (PTSD), along with its associated long-term comorbidities, will challenge the health care system. Multiple organ systems are adversely affected by PTSD, and PTSD is linked to cancer, arthritis, digestive disease, and cardiovascular disease. Evidence for a strong link between PTSD and cardiovascular disease is compelling, and this review describes current clinical data linking PTSD to cardiovascular disease, via inflammation, autonomic dysfunction, and the renin-angiotensin system. Recent clinical and preclinical evidence regarding the role of the renin-angiotensin system in the extinction of fear memory and relevance in PTSD-related immune and autonomic dysfunction is also addressed., (Copyright © 2015 the American Physiological Society.)

Background: Blunted nocturnal blood pressure (BP) dipping is an early marker of cardiovascular risk that is prevalent among African Americans., Purpose: We evaluated relationships of BP dipping to neighborhood and posttraumatic stress and sleep in urban residing young adult African Americans., Methods: One hundred thirty-six black, predominately African American, men and women with a mean age of 22.9 years (SD = 4.6) filled out surveys and were interviewed and had two, 24-h ambulatory BP recordings., Results: Thirty-eight percent had BP dipping ratios < .10. Wake after sleep onset (WASO), neighborhood disorder and neighborhood poverty rates but not posttraumatic stress symptoms, and other sleep measures correlated significantly with dipping ratios. Models with the neighborhood measures that also included WASO increased the explained variance., Conclusions: Studies elucidating mechanisms underlying effects of neighborhoods on BP dipping and the role of disrupted sleep, and how they can be mitigated are important directions for future research.

Objective: Insomnia is common following exposure to trauma and can occur independently or as a feature of posttraumatic stress disorder (PTSD). However, there is limited research identifying risk factors associated with the development of insomnia following exposure to a traumatic event. The goal of this study was to evaluate the role of specific trauma types in the risk for insomnia in a community sample of urban African Americans young adults., Methods: A sample of 554 nonclinical, urban, young adult African Americans was recruited for a larger study from which 465 participants were utilized for this study based on their completion of all study self-report measures. Participants were initially screened by phone to determine whether they provisionally met study criteria. Once selected, participants underwent informed consent and then completed a battery of self-report measures that included the Life Events Checklist, the PTSD Checklist, the Insomnia Severity Index, and the Fear of Sleep Index., Results: Of the seven trauma categories that were endorsed by at least 20% of the sample, results from logistic regression models indicated that sexual trauma, physical assault, accidents, natural disasters, and sudden violent death predicted insomnia independent of sex. However, PTSD symptom severity and nocturnal fears differentially influenced the relationship between trauma type and risk for insomnia., Conclusions: Exposure to specific types of trauma increases the odds of insomnia twofold to threefold. Additionally, PTSD symptom severity and nocturnal fears contribute differentially to the relationship between trauma exposure and insomnia suggesting the possibility of multiple underlying pathways., (© 2015 American Academy of Sleep Medicine.)

Objective: African-Americans have been found to experience increased rates of post-traumatic stress disorder (PTSD), obesity, and flatter diurnal cortisol slopes compared to other demographic groups. Further exploration, however, is needed to understand how PTSD impacts diurnal cortisol activity in obese African-American women. The purpose of the current study is to examine the relationship between salivary cortisol levels and PTSD in a sample of obese young adult African-American women and to examine how depression and insomnia influence the relationship., Methods: Thirty-four young adult African-American women (mean age = 24.0 years; mean BMI = 37.4 kg/m(2), 6/34 of the sample had a score of 40 or above on the PTSD Checklist (PCL) representing clinically significant PTSD) filled out questionnaires assessing PTSD, lifetime exposure to traumatic events, insomnia severity, and depression. A home-based assessment of salivary cortisol was provided upon awakening at 30 min and 1, 3, 6, and 12 h., Results: There was a significant interaction between PTSD status and diurnal cortisol activity (p < 0.04). There were trends for higher cortisol levels at awakening (p < 0.051) and 30 min post-awakening (p < 0.059) with PTSD. The significance of the interaction between PTSD and cortisol was attenuated by co-varying for depression and insomnia (p > 0.05)., Conclusion: PTSD, influenced by depression and insomnia symptoms, has an impact on diurnal cortisol activity in obese young adult African-American women., Competing Interests: Teletia R. Taylor, Ph.D., Kendra Van Kirk, BA, Denia Tapscott, M.D., Monet Bernard, BS, Juliana Llano, BS, and Thomas A. Mellman, M.D. declare that they have no conflict of interest.

Posttraumatic stress disorder (PTSD) has been associated with heightened nocturnal autonomic nervous system (ANS) arousal and sleep disturbances. It has been suggested that relationships between sleep and nocturnal ANS activity are influenced by insomnia; however, investigation of this relationship has been limited in PTSD. This study examined nocturnal ANS activity and its relationship to sleep in PTSD and resilience. Physically healthy young adult African Americans with current PTSD (n = 20) or who had never had PTSD despite exposure to a high-impact traumatic event (resilient, n = 18) were monitored with ambulatory electrocardiograms and actigraphy for 24-hr periods. Frequency-domain heart-rate variability measures, that is, low-frequency to high-frequency ratios (LF/HF), which index sympathetic nervous system activity, and normalized HF (nHF), which indexes parasympathetic nervous system activity were examined. Normalized HF during the time-in-bed period was lower for those with PTSD than those with resilience (p = .041). Total sleep time was strongly correlated with time-in-bed LF/HF (r = -.72) and nHF (r = .75) in the resilient group, but these were not correlated in the PTSD group. The results suggest elevated nocturnal ANS arousal and dissociation between ANS activity and total sleep time in PTSD., (Copyright © 2014 International Society for Traumatic Stress Studies.)

Study Objective: To determine relationships of polysomnographic (PSG) measures with posttraumatic stress disorder (PTSD) in a young adult, urban African American population., Design: Cross-sectional, clinical and laboratory evaluation., Setting: Community recruitment, evaluation in the clinical research unit of an urban University hospital., Participants: Participants (n = 145) were Black, 59.3% female, with a mean age of 23.1 y (SD = 4.8). One hundred twenty-one participants (83.4%) met criteria for trauma exposure, the most common being nonsexual violence. Thirty-nine participants (26.9%) met full (n = 19) or subthreshold criteria (n = 20) for current PTSD, 41 (28.3%) had met lifetime PTSD criteria and were recovered, and 65 (45%) were negative for PTSD., Measurements and Results: Evaluations included the Clinician Administered PTSD Scale (CAPS) and 2 consecutive nights of overnight PSG. Analysis of variance did not reveal differences in measures of sleep duration and maintenance, percentage of sleep stages, and the latency to and duration of uninterrupted segments of rapid eye movement (REM) sleep by study group. There were significant relationships between the duration of PTSD and REM sleep percentage (r = 0.53, P = 0.001), REM segment length (r = 0.43, P = 0.006), and REM sleep latency (r = -0.34, P < 0.03) among those with current PTSD that persisted when removing cases with, or controlling for, depression., Conclusions: The findings are consistent with observations in the literature of fragmented and reduced REM sleep with posttraumatic stress disorder (PTSD) relatively proximate to trauma exposure and nondisrupted or increased REM sleep with chronic PTSD., Citation: Mellman TA, Kobayashi I, Lavela J, Wilson B, Hall Brown TS. A relationship between REM sleep measures and the duration of posttraumatic stress disorder in a young adult urban minority population.

Background: Using laboratory-based polysomnography (PSG) we recently provided evidence of significantly prolonged sleep onset latency (SOL) and reduced latency to rapid eye movement (REM) sleep among non-depressed children with generalized anxiety disorder (GAD) compared to healthy age-matched controls. In the current study we conducted unattended ambulatory PSG in a new sample of children with GAD and controls in order to examine sleeping characteristics in the home environment., Method: Thirty-two children (ages of 7-11 years) including 16 children with primary GAD and 16 controls receiving no psychotropic medications were studied. The anxious group had a primary diagnosis of GAD without secondary mood disorders and controls were free of any medical or psychiatric diagnoses. All participants underwent structured diagnostic assessments and completed one night of home-based polysomnography (PSG)., Results: Children with GAD exhibited significantly higher sleep efficiency (SE) and fewer rapid eye movement (REM) sleep periods compared to controls. Self-reported somatic arousal during the pre-sleep period was negatively correlated with the percentage of total REM sleep among controls, but positively correlated with REM sleep percentage in the GAD group., Limitations: A small sample size and one night of PSG only., Conclusions: Home-based PSG recording do not provide evidence of disrupted sleep patterns in children with GAD. Contextual factors that better elucidate differences between laboratory and home-based sleep findings are suggested as important directions for future research., (Copyright © 2014 Elsevier B.V.

Emotional memory consolidation has been associated with rapid eye movement (REM) sleep, and recent evidence suggests that increased electroencephalogram spectral power in the theta (4-8 Hz) frequency range indexes this activity. REM sleep has been implicated in posttraumatic stress disorder (PTSD) as well as in emotional adaption. In this cross-sectional study, thirty young healthy African American adults with trauma exposure were assessed for PTSD status using the Clinician Administered PTSD Scale. Two consecutive night polysomnographic (PSG) recordings were performed and data scored for sleep stages. Quantitative electroencephalographic spectral analysis was used to measure theta frequency components sampled from REM sleep periods of the second-night PSG recordings. Our objective was to compare relative theta power between trauma-exposed participants who were either resilient or had developed PTSD. Results indicated higher right prefrontal theta power during the first and last REM periods in resilient participants compared with participants with PTSD. Right hemisphere prefrontal theta power during REM sleep may serve as a biomarker of the capacity for adaptive emotional memory processing among trauma-exposed individuals.

Disturbed sleep is a prominent feature of posttraumatic stress disorder (PTSD). PTSD and disrupted sleep have been independently linked to cognitive deficits; however, synergistic effects of PTSD and poor sleep on cognition have not been investigated. The purpose of this study was to examine the effects of PTSD symptoms and objectively measured disruptions to sleep on cognitive function. Forty-four young-adult African American urban residents comprised the study sample. The Clinician-Administered PTSD Scale (CAPS; Blake et al., 1995) was utilized to determine the severity of PTSD symptoms. Participants underwent 2 consecutive nights of polysomnography. The Automated Neuropsychological Assessment Metrics (Reeves, Winter, Bleiberg, & Kang, ) was utilized to assess sustained attention and the Rey Auditory Verbal Learning Test (Schmidt, ) was used to evaluate verbal memory. PTSD symptom severity, r(42) = .40, p = .007, was significantly associated with omission errors on the sustained attention task, and sleep duration, r(42) = .41, p = .006, and rapid eye movement sleep, r(42) = .43, p = .003, were positively correlated with verbal memory. There was an interaction of PTSD symptom severity and sleep duration on omission errors such that more than 7 hours 12 minutes of sleep mitigated attentional lapses that were associated with PTSD., (Copyright © 2014 International Society for Traumatic Stress Studies.)

The Fear of Sleep Inventory (FOSI) was developed to identify factors that contribute to sleep disturbances in individuals exposed to trauma. This investigation examined the psychometric properties of the FOSI in a sample of African American young adults residing in urban areas. A 5-factor structure was derived from an exploratory factor analysis and then verified by confirmatory factor analysis. FOSI factors were positively correlated with the severity of PTSD (rs = .30 to .58, all ps < .001) and insomnia symptoms (rs = .36 to .64, all ps < .001). Individuals with probable PTSD or insomnia had higher scores on the total FOSI and each of the factors compared to those without probable PTSD (all ps < .001; effect sizes: r = .32 to .62) or insomnia (all ps < .001; effect sizes: r = .42 to .70). These data expand the evidence that the FOSI identifies factors contributing to sleep disturbances in trauma-exposed individuals., (Copyright © 2014 International Society for Traumatic Stress Studies.)

African Americans residing in stressful urban environments have high rates of insomnia and short sleep duration, both of which are associated with adverse health outcomes. However, limited data exist that explore factors influencing inadequate sleep in this high-risk population. This study sought to evaluate the contributions of demographics, trauma, posttraumatic stress disorder (PTSD) symptoms, sleep fears, and neighborhood stress to both insomnia and short sleep in urban African American young adults. Data were analyzed from self-report measures completed by 378 participants 18-35 years of age. PTSD symptom severity and sleep fears were independently associated with insomnia severity, and sleep fears was associated with sleep duration. Results have implications for preventative health intervention strategies for urban African American young adults.

Health disparities are an immense challenge to American society. Clinical and Translational Science Awards (CTSAs) housed within the National Center for Advancing Translational Science (NCATS) are designed to accelerate the translation of experimental findings into clinically meaningful practices and bring new therapies to the doorsteps of all patients. Research Centers at Minority Institutions (RCMI) program at the National Institute on Minority Health and Health Disparities (NIMHD) are designed to build capacity for biomedical research and training at minority serving institutions. The CTSA created a mechanism fostering formal collaborations between research intensive universities and minority serving institutions (MSI) supported by the RCMI program. These consortium-level collaborations activate unique translational research approaches to reduce health disparities with credence to each academic institutions history and unique characteristics. Five formal partnerships between research intensive universities and MSI have formed as a result of the CTSA and RCMI programs. These partnerships present a multifocal approach; shifting cultural change and consciousness toward addressing health disparities, and training the next generation of minority scientists. This collaborative model is based on the respective strengths and contributions of the partnering institutions, allowing bidirectional interchange and leveraging NIH and institutional investments providing measurable benchmarks toward the elimination of health disparities., (© 2013 Wiley Periodicals, Inc.)

Objective: Obesity is highly prevalent and adds greatly to the risk of cardiovascular and metabolic diseases. However, a subset of the obese has been identified who do not appear to carry this risk. Some studies suggest that anthropomorphic correlates of risk, such as waist circumference, differ between African Americans and Whites and features of uncomplicated obesity have not been well characterized in this population. The goal of our study was to determine the prevalence and associated features of uncomplicated obesity, including relationships to waist circumference and the achievement of weight loss in primarily African American patients., Design: A retrospective chart review., Setting: Outpatient medically supervised weight loss program located at a teaching hospital in Washington, DC., Participants: Predominately adult African American females., Results: Thirty-one percent of our population had no documented metabolic or cardiovascular disease. This group was on average younger, but had similar waist circumference (44 +/- 13.8 vs 44 +/- 6.6 inches) and achieved similar mean weight loss at 3 months (9.9 +/- 10.4 vs 10.3 +/- 12.4 lbs.) as the group with comorbid conditions., Conclusions: Waist circumference was not an indicator of risk among African American women and achieved weight loss did not depend on pre-existing comorbidities.

Background: Polysomnographic (PSG) studies of children with psychiatric illness have primarily focused on depressed samples. Children with generalized anxiety disorder (GAD) report high rates of sleep problems yet investigation of objective sleep patterns in non-depressed children with GAD are unavailable. Identification of unique clinical features linking early GAD with sleep disturbance, including possible HPA activation during the pre-sleep period, is needed to inform effective treatments., Method: Thirty non-medicated, pre-pubescent children (ages 7-11 years) were assessed including 15 children with GAD and 15 matched healthy controls. Anxious children had GAD as their primary diagnosis and did not meet criteria for secondary mood disorders. All participants underwent structured diagnostic assessment and laboratory-based polysomnography (PSG). State anxiety and salivary cortisol were assessed prior to light out on the PSG night., Results: Children with GAD showed significantly increased sleep onset latency and reduced latency to rapid eye movement (REM) sleep compared to controls. Marginal differences in the form of reduced sleep efficiency and increased total REM sleep also were found in the GAD group. Pre-sleep anxiety and cortisol levels did not differ between the two groups., Limitations: A small sample size, time-limited assessment of cortisol, and possible first night effects should be considered., Conclusions: Results of this study provide initial evidence of PSG-based differences in children with GAD compared to controls. Follow-up studies are needed to explore the course of sleep alterations and whether targeting sleep problems early in the course of GAD might improve clinical outcomes., (Copyright © 2012 Elsevier B.V.

Women are approximately twice as likely as men to develop posttraumatic stress disorder (PTSD) after trauma exposure. Mechanisms underlying this difference are not well understood. Although sleep is recognized to have a critical role in PTSD and physical and psychological health more generally, research into the role of sleep in PTSD sex differences has been only recent. In this article, we review both animal and human studies relevant to sex differences in sleep and PTSD with an emphasis on the roles of sex hormones. Sleep impairment including insomnia, trauma-related nightmares, and rapid-eye-movement (REM) sleep fragmentation has been observed in individuals with chronic and developing PTSD, suggesting that sleep impairment is a characteristic of PTSD and a risk factor for its development. Preliminary findings suggested sex specific patterns of sleep alterations in developing and established PTSD. Sleep maintenance impairment in the aftermath of trauma was observed in women who subsequently developed PTSD, and greater REM sleep fragmentation soon after trauma was associated with developing PTSD in both sexes. In chronic PTSD, reduced deep sleep has been found only in men, and impaired sleep initiation and maintenance with PTSD have been found in both sexes. A limited number of studies with small samples have shown that sex hormones and their fluctuations over the menstrual cycle influenced sleep as well as fear extinction, a process hypothesized to be critical to the pathogenesis of PTSD. To further elucidate the possible relationship between the sex specific patterns of PTSD-related sleep alterations and the sexually dimorphic risk for PTSD, future studies with larger samples should comprehensively examine effects of sex hormones and the menstrual cycle on sleep responses to trauma and the risk/resilience for PTSD utilizing various methodologies including fear conditioning and extinction paradigms and animal models.

Background: Fear of recurrence (FOR) is a psychological concern that has been studied extensively in cancer survivors but has not been adequately examined in African-American breast cancer survivors., Purpose: This exploratory study describes the extent and nature of FOR in African-American breast cancer survivors. FOR is examined in relation to socio-demographic characteristics, treatment-related characteristics, psychological distress, and quality of life (QOL)., Methods: Participants completed questionnaires assessing FOR, psychological distress, QOL, and demographic and treatment characteristics. Pearson r correlations, t tests, and ANOVAs were used to determine the association between FOR and demographic and treatment-related characteristics. Hierarchical multiple regression models were performed to investigate the degree to which FOR dimensions account for the variance in QOL and psychological distress., Results: Fifty-one African-American breast cancer survivors participated in this study. The mean age of participants was 64.24 (SD = 12.3). Overall fears as well as concerns about death and health were rated as low to moderate. Role worries and womanhood worries were very low. Inverse relationships were observed between age and FOR dimensions. FOR was positively correlated with measures of psychological distress and negatively correlated with QOL. FOR significantly accounted for a portion of the variance in QOL and distress after controlling for other variables., Conclusions: This study suggests that African-American women in this sample demonstrated some degree of FOR. Results indicate that FOR among African-American breast cancer survivors decreases with age and time since diagnosis and co-occurs with psychological distress as well as diminished quality of life.

Objectives: The goals of this study were (i) to report the prevalence and nature of sleep disturbances, as determined by clinically significant insomnia symptoms, in a sample of African-American breast cancer survivors; (ii) to assess the extent to which intrusive thoughts about breast cancer and fear of recurrence contributes to insomnia symptoms; and (iii) to assess the extent to which insomnia symptoms contribute to fatigue., Methods: African-American breast cancer survivors completed surveys pertaining to demographics, medical history, insomnia symptoms, and intrusive thoughts about breast cancer, fear of cancer recurrence, and fatigue. Hierarchical regression models were performed to investigate the degree to which intrusive thoughts and concerns of cancer recurrence accounted for the severity of insomnia symptoms and insomnia symptom severity's association with fatigue., Results: Forty-three percent of the sample was classified as having clinically significant sleep disturbances. The most commonly identified sleep complaints among participants were sleep maintenance, dissatisfaction with sleep, difficulty falling asleep, and early morning awakenings. Intrusive thoughts about breast cancer were a significant predictor of insomnia symptoms accounting for 12% of the variance in insomnia symptom severity. After adjusting for covariates, it was found that insomnia symptom severity was independently associated with fatigue accounting for 8% of variance., Conclusions: A moderate proportion of African-American breast cancer survivors reported significant problems with sleep. Sleep disturbance was influenced by intrusive thoughts about breast cancer, and fatigue was associated with the severity of participants' insomnia symptoms. This study provides new information about sleep-related issues in African-American breast cancer survivors., (Copyright © 2011 John Wiley & Sons, Ltd.)

Study Objectives: Although reports of sleep disturbances are common among individuals with posttraumatic stress disorder (PTSD), results of polysomnographic (PSG) studies have inconsistently documented abnormalities and have therefore suggested "sleep state misperception." The authors' study objectives were to compare sleep parameters measured objectively and subjectively in the laboratory and at home in civilians with and without trauma exposure and PTSD., Design: Cross-sectional study., Setting: PSG recordings in a sleep laboratory and actigraphic recordings in participants' homes., Participants: One hundred three urban-residing African Americans with and without trauma exposure and PTSD who participated in a larger study., Interventions: N/A., Measurements: Sleep parameters (total sleep time [TST], sleep onset latency [SOL], and wake after sleep onset [WASO]) were assessed using laboratory PSG and home actigraphy. A sleep diary was completed in the morning after PSG and actigraphy recordings. Habitual TST, SOL, and WASO were assessed using a sleep questionnaire. The Clinician Administered PTSD Scale was administered to assess participants' trauma exposure and PTSD diagnostic status., Results: Participants, regardless of their trauma exposure/PTSD status, underestimated WASO in the diary and questionnaire relative to actigraphy and overestimated SOL in the diary relative to PSG. Among participants with current PTSD, TST diary estimates did not differ from the actigraphy measure in contrast with those without current PTSD who overestimated TST. No other significant group differences in discrepancies between subjective and objective sleep measures were found., Conclusions: Discrepancies between subjectively and objectively measured sleep parameters were not associated with trauma exposure or PTSD. This challenges prior assertions that individuals with PTSD overreport their sleep disturbances.

Women have a greater risk of developing posttraumatic stress disorder (PTSD) after exposure to trauma. Although sleep abnormalities have been implicated in the development of PTSD, gender differences in sleep soon after a traumatic event have not been investigated. This secondary analysis examined sleep characteristics using polysomnography in 13 female and 22 male trauma patients within a month of their traumatic injuries and assessed PTSD symptoms at 2-months post-injury. Results revealed more wake after sleep onset in women who developed PTSD compared to men who developed PTSD. Women with subsequent PTSD also had less total sleep time than women without subsequent PTSD. Findings suggest possible contributions of impaired sleep maintenance to the development of PTSD in women.

Posttraumatic stress disorder (PTSD) is common following the experience of a natural disaster and sleep disturbance is an important influence on its course in adults, but little research is available examining sleep and PTSD in youths. This study's objective was to evaluate the role of sleep disturbance and the developmentally influenced factor of fear of sleeping alone in the maintenance of posttraumatic stress (PTS) symptoms in youths. Deidentified data of 191 Hurricane Katrina survivors ages 8 to 15 were used in this study. We found cross-sectional relationships of sleep disturbance and fear of sleeping alone with PTS symptom severity. Longitudinal analysis also indicated that general sleep disturbance at 24 months (T1) was predictive of PTS symptoms severity at 30 months (T2) even after adjusting for PTS symptom severity at T1, age, sex, and continued disrepair to the home. These results have implications for intervention strategies among youth exposed to traumatic events., (Copyright © 2011 International Society for Traumatic Stress Studies.)

Background: Posttraumatic stress disorder (PTSD) is a common, potentially disabling, underdiagnosed, and under-treated illness. Primary care physicians assume a critical role in the diagnosis, treatment, and referral of African Americans with PTSD since mental health access is limited for this population. This study is an examination of PTSD treatment of African Americans in the primary care setting. Actual treatment provision is contrasted with existing evidence-based PTSD treatment guidelines., Method: Researchers screened 738 consenting, mostly African American, adults in 4 academically affiliated primary care offices for both trauma exposure and mental health symptoms, including PTSD., Results: Employing criteria from the Diagnostic and Statistical Manual of Mental Disorders (Fourth Edition, Text Revision) (DSM-IV), investigators diagnosed 91 of the participants with current PTSD using the Structured Clinical Interview for DSM and the clinician-administered of PTSD Scale for DSM-IV. Treatment statistics include: 69.2% (n=63) had never received treatment from a mental health provider: 18.6% (n=17) were currently seeing a mental health practitioner; nearly half (47.9%, n=24) of a subsample had never discussed traumatic event exposure or mental health symptoms with their primary care doctor; 32% (n=29) were prescribed psychotropic medication and only 18.6% (n=17) were participating in any form of psychotherapy. Concurrent psychiatric disorders were found in 46.2% (n = 42) of the participants with PTSD., Conclusion: Most African American adult primary care patients with PTSD were either undiagnosed or undertreated in this inner-city setting. These results demonstrate a clear need to improve screening and treatment services. Both individual (provider and patient) and system-based changes will be required to meet the demonstrated clinical need.

Background: Patients with penetrating injuries are known to have worse outcomes than those with blunt trauma. We hypothesize that within each injury mechanism there should be no outcome difference between insured and uninsured patients., Methods: The National Trauma Data Bank version 7 was analyzed. Patients aged 65 years and older and burn patients were excluded. The insurance status was categorized as insured (private, government/military, or Medicaid) and uninsured. Multivariate analysis adjusted for insurance status, mechanism of injury, age, race, sex, injury severity score, shock, head injury, extremity injury, teaching hospital status, and year., Results: A total of 1,203,243 patients were analyzed, with a mortality rate of 3.7%. The death rate was significantly higher in penetrating trauma patients versus blunt trauma patients (7.9% vs 3.0%; P < .001), and higher in the uninsured (5.3% vs 3.2%; P < .001). On multivariate analysis, uninsured patients had an increased odds of death than insured patients, in both penetrating and blunt trauma patients. Penetrating trauma patients with insurance still had a greater risk of death than blunt trauma patients without insurance., Conclusions: Insurance status is a potent predictor of outcome in both penetrating and blunt trauma., (Copyright 2010 Elsevier Inc.
