RESUMEN

BACKGROUND: The Whole Health model of the U.S. Department of Veterans Affairs (VA) emphasizes holistic self-care and multimodal approaches to improve pain, functioning, and quality of life. wHOPE (Whole Health Options and Pain Education) seeks to be the first multisite pragmatic trial to establish evidence for the VA Whole Health model for chronic pain care. DESIGN: wHOPE is a pragmatic randomized controlled trial comparing a Whole Health Team (WHT) approach to Primary Care Group Education (PC-GE); both will be compared to Usual VA Primary Care (UPC). The WHT consists of a medical provider, a complementary and integrative health (CIH) provider, and a Whole Health coach, who collaborate with VA patients to create a Personalized Health Plan emphasizing CIH approaches to chronic pain management. The active comparator, PC-GE, is adapted group cognitive behavioral therapy for chronic pain. The first aim is to test whether the WHT approach is superior to PC-GE and whether both are superior to UPC in decreasing pain interference in functioning in 750 veterans with moderate to severe chronic pain (primary outcome). Secondary outcomes include changes in pain severity, quality of life, mental health symptoms, and use of nonpharmacological and pharmacological therapies for pain. Outcomes will be collected from the VA electronic health record and patient-reported data over 12 months of follow-up. Aim 2 consists of an implementation-focused process evaluation and budget impact analysis. SUMMARY: This trial is part of the Pain Management Collaboratory, which seeks to create national-level infrastructure to support evidence-based nonpharmacological pain management approaches for veterans and military service personnel.

RESUMEN

BACKGROUND: Mental disorders are a leading cause of global disability, driven primarily by depression and anxiety. Most of the disease burden is in Low and Middle Income Countries (LMICs), where 75% of adults with mental disorders have no service access. Our research team has worked in western Kenya for nearly ten years. Primary care populations in Kenya have high prevalence of Major Depressive Disorder (MDD) and Posttraumatic Stress Disorder (PTSD). To address these treatment needs with a sustainable, scalable mental health care strategy, we are partnering with local and national mental health stakeholders in Kenya and Uganda to identify 1) evidence-based strategies for first-line and second-line treatment delivered by non-specialists integrated with primary care, 2) investigate presumed mediators of treatment outcome and 3) determine patient-level moderators of treatment effect to inform personalized, resource-efficient, non-specialist treatments and sequencing, with costing analyses. Our implementation approach is guided by the Exploration, Preparation, Implementation, Sustainment (EPIS) framework. METHODS/DESIGN: We will use a Sequential, Multiple Assignment Randomized Trial (SMART) to randomize 2710 patients from the outpatient clinics at Kisumu County Hospital (KCH) who have MDD, PTSD or both to either 12 weekly sessions of non-specialist-delivered Interpersonal Psychotherapy (IPT) or to 6 months of fluoxetine prescribed by a nurse or clinical officer. Participants who are not in remission at the conclusion of treatment will be re-randomized to receive the other treatment (IPT receives fluoxetine and vice versa) or to combination treatment (IPT and fluoxetine). The SMART-DAPPER Implementation Resource Team, (IRT) will drive the application of the EPIS model and adaptations during the course of the study to optimize the relevance of the data for generalizability and scale -up. DISCUSSION: The results of this research will be significant in three ways: 1) they will determine the effectiveness of non-specialist delivered first- and second-line treatment for MDD and/or PTSD, 2) they will investigate key mechanisms of action for each treatment and 3) they will produce tailored adaptive treatment strategies essential for optimal sequencing of treatment for MDD and/or PTSD in low resource settings with associated cost information - a critical gap for addressing a leading global cause of disability. TRIAL REGISTRATION: ClinicalTrials.gov NCT03466346, registered March 15, 2018.

RESUMEN

Sleep and wakefulness control in the mammalian brain requires the coordination of various discrete interconnected neurons. According to the most conventional sleep model, wake-promoting neurons (WPNs) and sleep-promoting neurons (SPNs) compete for network dominance, creating a systematic "switch" that results in either the sleep or awake state. WPNs and SPNs are ubiquitous in the brainstem and diencephalon, areas that together contain <1% of the neurons in the human brain. Interestingly, many of these WPNs and SPNs co-express and co-release various types of the neurotransmitters that often have opposing modulatory effects on the network. Co-transmission is often beneficial to structures with limited numbers of neurons because it provides increasing computational capability and flexibility. Moreover, co-transmission allows subcortical structures to bi-directionally control postsynaptic neurons, thus helping to orchestrate several complex physiological functions such as sleep. Here, we present an in-depth review of co-transmission in hypothalamic WPNs and SPNs and discuss its functional significance in the sleep-wake network.

RESUMEN

Posttraumatic stress disorder (PTSD) is associated with fear response system dysregulation. Research has shown that the anterior cingulate cortex (ACC) may modulate the fear response and that individuals with PTSD have abnormalities in ACC structure and functioning. Our objective was to assess whether ACC volume moderates the relationship between PTSD and fear-potentiated psychophysiological response in a sample of Gulf War Veterans. 142 Veteran participants who were associated with a larger study associated with Gulf War Illness were exposed to no threat, ambiguous threat, and high threat conditions in a fear conditioned startle response paradigm and also provided MRI imaging data. PTSD was assessed using the Clinician Administered PTSD Scale (CAPS). Decreased caudal ACC volume predicted greater psychophysiological responses with a slower habituation of psychophysiological magnitudes across trials (p < 0.001). PTSD diagnosis interacted significantly with both caudal and rostral ACC volumes on psychophysiological response magnitudes, where participants with PTSD and smaller rostral and caudal ACC volumes had greater psychophysiological magnitudes across trials (p < 0.05 and p < 0.001, respectively) and threat conditions (p < 0.05 and p < 0.005). Our results suggest that ACC volume may moderate both threat sensitivity and threat response via impaired habituation in individuals who have been exposed to traumatic events. More research is needed to assess whether ACC size and these associated response patterns are due to neurological processes resulting from trauma exposure or if they are indicative of a premorbid risk for PTSD subsequent to trauma exposure.

RESUMEN

OBJECTIVE: Innovative approaches to the treatment of war-related posttraumatic stress disorder (PTSD) are needed. We report on secondary psychological outcomes of a randomized controlled trial of integrative exercise (IE) using aerobic and resistance exercise with mindfulness-based principles and yoga. We expected-in parallel to observed improvements in PTSD intensity and quality of life-improvements in mindfulness, interoceptive bodily awareness, and positive states of mind. METHOD: A total of 47 war veterans with PTSD were randomized to 12-week IE versus waitlist. Changes in mindfulness, interoceptive awareness, and states of mind were assessed by self-report standard measures. RESULTS: Large effect sizes for the intervention were observed on Five-Facet Mindfulness Questionnaire Non-Reactivity (d = .85), Multidimensional Assessment of Interoceptive Awareness Body Listening (d = .80), and Self-Regulation (d = 1.05). CONCLUSION: In a randomized controlled trial of a 12-week IE program for war veterans with PTSD, we saw significant improvements in mindfulness, interoceptive bodily awareness, and positive states of mind compared to a waitlist.

RESUMEN

BACKGROUND: Posttraumatic stress disorder (PTSD) is prevalent among military veterans and is associated with significant negative health outcomes. However, stigma and other barriers to care prevent many veterans from pursuing traditional mental health treatment. We developed a group-based Integrative Exercise (IE) program combining aerobic and resistance exercise, which is familiar to veterans, with mindfulness-based practices suited to veterans with PTSD. This study aimed to evaluate the effects of IE on PTSD symptom severity and quality of life, as well as assess the feasibility and acceptability of IE. METHODS: Veterans (N = 47) were randomized to either IE or waitlist control (WL). Veterans in IE were asked to attend three 1-h group exercise sessions for 12 weeks. RESULTS: Compared with WL, veterans randomized to IE demonstrated a greater reduction in PTSD symptom severity (d = -.90), a greater improvement in psychological quality of life (d = .53) and a smaller relative improvement in physical quality of life (d = .30) Veterans' ratings of IE indicated high feasibility and acceptability. LIMITATIONS: The sample was relatively small and recruited from one site. The comparison condition was an inactive control. CONCLUSIONS: This initial study suggests that IE is an innovative approach to treating veterans with symptoms of PTSD that reduces symptoms of posttraumatic stress and improves psychological quality of life. This approach to recovery may expand the reach of PTSD treatment into non-traditional settings and to veterans who may prefer a familiar activity, such as exercise, over medication or psychotherapy.

RESUMEN

This paper is based upon a panel discussion "What I Have Changed My Mind About and Why" held on 5 November in New Orleans, Louisiana (USA), as part of the ISTSS 2015 annual meeting "Back to Basics: Integrating Clinical and Scientific Knowledge to Advance the Field of Trauma." The panel was chaired by Professor Dr. Rachel Yehuda of the Icahn School of Medicine at Mount Sinai and the James J. Peters Veterans Affairs, and included five clinician-scholars who exchanged thoughts about what they have changed their minds about over the years: Dr. David Spiegel, Dr. Steven Southwick, Dr. Lori Davis, Dr. Thomas Neylan, and Dr. John Krystal. This paper provides a summary of the salient points made by each expert and the questions and discussion that ensured. Major issues raised included the increasingly clear limitations to the fear-based model that has advanced the field. While treatments for PTSD have improved, there are some aspects of trauma exposure that cannot be entirely repaired. Research providing an evidence base to treatment has led to overly specific treatment guidelines that may obscure more general principles of effective treatment. Treatment might be viewed as a way to increase the plasticity of the brain in the context of processing social cues. A variety of novel and integrative therapies include comprehensive holistic care, exercise, returning to competitive work, logotherapy, mindfulness, enhancing well-being and resilience, and medications with novel mechanisms, such as ketamine.

RESUMEN

BACKGROUND: Posttraumatic stress disorder (PTSD) has been most consistently associated with exaggerated physiologic reactivity to startling sounds when such sounds occur in threatening contexts. There is conflicting evidence about whether startle hyperreactivity is a preexisting vulnerability factor for PTSD or an acquired result of posttrauma neural sensitization. Until now, there have been no prospective studies of physiologic reactivity to startling sounds in threatening contexts as predictors of PTSD symptoms. METHODS: One hundred and thirty-eight police academy cadets without current psychopathology were exposed to repeated 106-dB startling sounds under increasing (low, medium, or high) threat of mild electric shock while their eye-blink electromyogram, skin conductance, heart rate, and subjective fear responses were recorded. Measures of response habituation were also calculated. Following 1 year of exposure to police-related trauma, these participants were assessed for PTSD symptom severity. RESULTS: After accounting for other baseline variables that were predictive of PTSD symptom severity (age and general psychiatric distress), more severe PTSD symptoms were prospectively and independently predicted by the following startle measures: greater subjective fear under low threat, greater skin conductance under high threat, and slower skin conductance habituation. CONCLUSIONS: These results imply that hypersensitivity to contextual threat (indexed by greater fear under low threat), elevated sympathetic nervous system reactivity to explicit threat (indexed by larger responses under high threat), and failure to adapt to repeated aversive stimuli (evidenced by slower habituation) are all unique preexisting vulnerability factors for greater PTSD symptom severity following traumatic stress exposure. These measures may eventually prove useful for preventing PTSD.

RESUMEN

Magnetic resonance spectroscopic imaging (MRSI) studies suggest hippocampal abnormalities in posttraumatic stress disorder (PTSD), whereas findings of volume deficits in the hippocampus, as revealed with magnetic resonance imaging (MRI), have been inconsistent. Co-morbidities of PTSD, notably alcohol abuse, may have contributed to the inconsistency. The objective was to determine whether volumetric and metabolic abnormalities in the hippocampus and other brain regions are present in PTSD, independent of alcohol abuse. Four groups of subjects, PTSD patients with (n=28) and without (n=27) alcohol abuse and subjects negative for PTSD with (n=23) and without (n=26) alcohol abuse, were enrolled in this observational MRI and MRSI study of structural and metabolic brain abnormalities in PTSD. PTSD was associated with reduced N-acetylaspartate (NAA) in both the left and right hippocampus, though only when normalized to creatine levels in the absence of significant hippocampal volume reduction. Furthermore, PTSD was associated with reduced NAA in the right anterior cingulate cortex regardless of creatine. NAA appears to be a more sensitive marker for neuronal abnormality in PTSD than brain volume. The alteration in the anterior cingulate cortex in PTSD has implications for fear conditioning and extinction.

RESUMEN

Childhood trauma may confer risk for adult psychopathology by altering emotional and physiological responses to subsequent stressors. Few studies have distinguished effects of childhood trauma from effects of current Axis I psychopathology on adult psychophysiological reactivity. The authors exposed 90 psychiatrically healthy police cadets to startling sounds under increasing threat of shock while assessing their eyeblink electromyogram (EMG), skin conductance (SC), and heart rate responses. When compared with those who did not endorse early trauma (n = 65), cadets reporting childhood trauma (n = 25) reported less positive emotion and showed greater SC responses across all threat levels. They also showed threat-dependent elevations in reported negative emotions and EMG responses. Results suggest that childhood trauma may lead to long-lasting alterations in emotional and psychophysiological reactivity even in the absence of current Axis I psychopathology.

RESUMEN

BACKGROUND: We examined P300 measures in patients with posttraumatic stress disorder (PTSD) and control subjects at two different time points to determine event-related potential (ERP) stability over time and the relationship of changes in ERPs to changes in symptom levels. METHODS: Auditory and visual P300 was recorded in a three-condition novelty oddball task in 25 male subjects with combat-related PTSD and 15 male combat-exposed normal control subjects at two time points separated by 6-12 months. Regression analyses were conducted to compare the temporal stability of ERP measures in PTSD and control subjects. Variability in ERP measures over time within PTSD subjects was examined for association with changes in symptom levels. RESULTS: There were no significant differences in P300 amplitude or latency in PTSD versus control subjects at either time point, regardless of stimulus type (target, novel) or modality (auditory, visual). Nine of 24 P300 measures were significantly less predictable over time in the PTSD group compared to control subjects. Variability of P300 measures over time was not associated with fluctuations in symptoms of depression or PTSD. CONCLUSIONS: P300 ERPs are more variable cross-sectionally and over time in PTSD subjects compared to trauma exposed control subjects. Measures of variability about the group mean appear to be more informative about the cognitive electrophysiology of PTSD than measures of central tendency.
