Background/UNASSIGNED:Although recent data in healthy humans suggestthat treatment with intranasal oxytocin (OT) may facilitate extinction recall,to date, little is known about the effects of OT on memory consolidationprocesses. Aim/UNASSIGNED:To examine the effect of intranasal administration of OT compared with placebo on memory consolidation blockade of a de novo fear memory in a classical 2-day fear conditioning procedure. Results/UNASSIGNED:(4, 112)=0.76, p=0.56). Conclusion/UNASSIGNED:Our results suggest that OT administered in a double-blind fashion immediately after fear conditioning does not significantly reduce consolidation of fear learning as measured by a differential skin conductance response tested at the beginning of extinction.

Exposure therapy for social anxiety disorder (SAD) utilizes fear extinction, a memory process enhanced by sleep. We investigated whether naps following exposure sessions might improve symptoms and biomarkers in response to social stress in adults undergoing 5-week exposure-based group SAD therapy. Thirty-two participants aged 18-39 (18 females) with SAD were randomized. Before and after treatment, participants completed the Liebowitz Social Anxiety Scale (LSAS) and underwent a Trier Social Stress Test with psychophysiological monitoring (mpTSST) that included skin conductance (SCL), electromyographic (EMG) and electrocardiographic recording, and an auditory startle procedure while anticipating the social stressor. At sessions 3 and 4, exposure was followed by either a 120-min polysomnographically monitored sleep opportunity (Nap, N = 17) or wakefulness (Wake, N = 15). Primary hypotheses about SAD symptom change (LSAS) and EMG blink-startle response failed to differ with naps, despite significant symptom improvement (LSAS) with therapy. Some secondary biomarkers, however, provided preliminary support for enhanced extinction learning with naps, with trend-level Time (pre-, post-treatment) × Arm interactions and significant reduction from pre- to post treatment in the Nap arm alone for mpTSST SCL and salivary cortisol rise. Because of the small sample size and limited sleep duration, additional well-powered studies with more robust sleep interventions are indicated.

Objective/UNASSIGNED:To evaluate the frequency with which migraine patients initiated behavioral migraine treatment following a headache specialist recommendation and the predictors for initiating behavioral migraine treatment. Methods/UNASSIGNED:We conducted a prospective cohort study of consecutive patients diagnosed with migraine to examine whether the patients initiated behavioral migraine treatment following a provider recommendation. The primary outcome was scheduling the initial visit for behavioral migraine treatment. Patients who initiated behavioral migraine treatment were compared with those who did not (demographics, migraine characteristics, and locus of control) with analysis of variance and chi-square tests. Results/UNASSIGNED:Of the 234 eligible patients, 69 (29.5%) were referred for behavioral treatment. Fifty-three (76.8%) patients referred for behavioral treatment were reached by phone. The mean duration from time of referral to follow-up was 76  (median 76, SD = 45) days. Thirty (56.6%) patients initiated behavioral migraine treatment. There was no difference in initiation of behavioral migraine treatment with regard to sex, age, age of diagnosis, years suffered with headaches, health care utilization visits, Migraine Disability Assessment Screen, and locus of control (P > 0.05). Patients who had previously seen a psychologist for migraine were more likely to initiate behavioral migraine treatment than patients who had not. Time constraints were the most common barrier cited for not initiating behavioral migraine treatment. Conclusions/UNASSIGNED:Less than one-third of eligible patients were referred for behavioral treatment, and only about half initiated behavioral migraine treatment. Future research should further assess patients' decisions regarding behavioral treatment initiation and methods for behavioral treatment delivery to overcome barriers to initiating behavioral migraine treatment.

Underutilization of mental health care is a significant problem among veterans. Offering peer support may improve mental health care engagement. This observational pilot study was conducted using an institutional review board-approved data repository to preliminarily evaluate the association and potential impact of a clinic-based veteran peer outreach strategy on treatment engagement and dropout. Veteran peer outreach coordinators (VPOCs) provided systematic contact (a) within 1 week after clinical evaluation and (b) 1 month after the patient's first treatment session to patients entering treatment at a specialty mental health clinic that provides military-informed mental health care to post-9/11 veterans and service members. Individuals were 102 consecutive Operation Enduring Freedom/Operation Iraqi Freedom/Operation New Dawn veteran psychotherapy referrals seen at an outpatient clinic. At 6 months, participants who received both contacts from VPOC had more psychotherapy sessions (M = 10.85, SD = 8.25) compared with those who had received no contact (M = 5.47, SD = 6.41) from VPOCs, t = 2.56, p < .05. The dropout rate was also significantly lower for those who received both peer outreach contacts (17.39%) compared with those who received only 1 VPOC contact (51.11%) or no VPOC contact (43.75%), chi2 = 7.27, p < .05. Veteran peer outreach may be associated with better engagement in mental health treatment and lower dropout. (PsycINFO Database Record

Mild traumatic brain injury (mTBI) is commonly reported in recent combat Veterans. While the majority resolve, some Veterans develop postconcussive symptoms (PCS). Previous research suggests these symptoms are not specific to head injury and are often associated with psychiatric symptoms. The current study examines the relative contributions of posttraumatic stress, depressive symptoms, and TBI on postconcussive symptoms, and explores whether the relationship remains after controlling for symptom overlap. Two hundred eighteen combat Veterans from Operation Iraqi Freedom (OIF), Operation Enduring Freedom (OEF), and Operation New Dawn (OND) provided the data for this study as part of a baseline evaluation for inclusion into larger treatment study for posttraumatic stress disorder (PTSD). Participants completed the Brief Traumatic Brain Injury Screen (BTBIS), Neurobehavioral Symptom Inventory (NSI), PTSD Checklist-Stressor Version (PCL-S), Beck Depression Inventory-II (BDI-II). Significant differences in NSI total score between individuals with and without history of TBI were not found. A series of regression analyses demonstrated that Depression and PTSD were significant predictors of NSI score even after removal of NSI symptoms that overlap with PTSD or depression. TBI status was also a significant predictor of PCS in most models, but its relative contribution was much smaller than that of depression and PTSD. Within PTSD symptoms, hyperarousal cluster was a significant predictor of NSI scores. Findings demonstrate that depression and PTSD are related to PCS beyond similarities in construct. Further, within a primarily PTSD treatment-seeking population, these psychiatric symptoms appear to be a stronger contributor than TBI.

Background: There are limited data on the adherence of migraine patients to recommendations for evidence-based behavioral treatments. Among patients seen by a headache specialist, we sought to determine rates of adherence to recommended behavioral treatments and barriers to adherence. We also sought to determine whether psychosocial factors such as migraine related disability, locus of control and self-efficacy were associated with adherence to migraine behavioral treatment recommendations. Methods: We conducted a prospective study of consecutive patients presenting to four headache specialists who were diagnosed with migraine at our Headache Center from 2016-2017 to examine whether they adhered to the recommendation to receive behavioral treatment. The primary outcome was whether patients had scheduled at least one visit for behavioral treatment. Descriptive statistics were reported. Patients who made an appointment for behavioral treatment were compared to those who did not across multiple categories including demographics, migraine characteristics, and personal beliefs with ANOVA and chi-square tests. Qualitative analyses were also done for open ended survey questions. Results: Of the 234 eligible patients, 69 (29.5%) were referred for behavioral treatment. Fifty-three (76.8%) patients referred for behavioral treatment were successfully reached by phone. Mean duration from time of referral to follow-up was 76 days (median 76, SD5 45). Just over half of patients (56.6%, N530) adhered to the recommendation for behavioral treatment. Patients who had previously seen a psychologist for their migraines were more likely to adhere to the behavioral treatment recommendation than patients who had not. Time constraints were the most common barrier cited for not scheduling a behavioral treatment appointment. Conclusion: Less than one third of eligible patients were referred for behavioral treatment and only about half adhered to the recommendation to schedule an appointment for behavioral treatment. More research should assess factors which might play a role in adherence to migraine behavioral treatment recommendations

BACKGROUND:Although depression and anxiety have been associated with shorter telomeres in cross-sectional studies, the data regarding the prospective relations of depression and anxiety to accelerated telomere length shortening are limited and findings are mixed. We prospectively examined relations of baseline depression and phobic anxiety to subsequent 11-year change in relative leukocyte telomere lengths (LTLs). METHODS:We selected 1,250 women from a subcohort of the Nurses' Health Study who provided blood specimens at both blood collections (1989-1990 and 2000-2001). Depression was defined by self-reported regular antidepressant use or presence of severe depressive symptoms; anxiety symptoms were assessed using the Crown-Crisp Experiential Index. Using quantitative real-time polymerase chain reaction assay, LTLs were measured as the copy number ratio of telomere repeat to a single control gene. Changes in LTLs were defined in three ways: absolute change, symmetrized percent change, and decile shift. RESULTS:Overall, there were no statistically significant associations of depression or phobic anxiety to subsequent 11-year LTL shortening, despite a point estimates in the direction of greater telomere shortening among participants with versus without depression, across all three metrics of telomere change. The strongest predictor of LTL change was baseline telomere length, and regression-to-the-mean was observed. CONCLUSION/CONCLUSIONS:Baseline depression and phobic anxiety were not significantly associated with 11-year attrition in LTLs among 1,250 mid-life and older women. However, a suggestion of depression and greater subsequent LTL attrition, while not statistically significant, may warrant further inquiry, particularly in prospective studies with larger sample sizes and broader windows of the lifespan.
