Neurobiology of the Rapid-Acting Antidepressant Effects of Ketamine: Impact and Opportunities.

The discovery of the rapid-acting antidepressant effects of ketamine has 1) led to a paradigm shift in our perception of what is possible in treating severe depression; 2) spurred a wave of basic, translation, and clinical research; and 3) provided an unprecedented investigational tool to conduct longitudinal mechanistic studies that may capture behavioral changes as complex as clinical remission and relapse within hours and days of treatment. Unfortunately, these advances did not yet translate into clinical biomarkers or novel treatments, beyond ketamine. In contrast to slow-acting antidepressants, in which targeting monoaminergic receptors identified several efficacious drugs with comparable mechanisms, the focus on the receptor targets of ketamine has failed in several clinical trials over the past decade.

Association of Temporary Financial Assistance With Housing Stability Among US Veterans in the Supportive Services for Veteran Families Program.

Importance: Temporary financial assistance (TFA) for housing-related expenses is a key component of interventions to prevent homelessness or to quickly house those who have become homeless. Through the US Department of Veterans Affairs (VA) Supportive Services for Veteran Families (SSVF) program, the department provides TFA to veterans in need of housing assistance.

Objective: To assess the association between TFA and housing stability among US veterans enrolled in the SSVF program.

Dispositional gratitude and mental health in the U.S. veteran population: Results from the National Health and Resilience Veterans Study.

Dispositional gratitude may be linked to positive mental health outcomes, yet population-based data on this association are lacking. Military veterans are an ideal population in which to examine this question given high rates of psychiatric morbidities and efforts to promote psychological resilience in this population. Data were analyzed from a nationally representative sample of 3151 U.

Healthcare Resource Utilization Following a Discharge Against Medical Advice: An Analysis of Commercially Insured Adults.

Background: A discharge against medical advice (DAMA) is associated with adverse health outcomes. Its association with postdischarge healthcare resource utilization (HcRU) outside an inpatient setting is unknown. This information can help us understand how a DAMA may affect healthcare-seeking behavior following a hospital stay.

Barriers and facilitators to the implementation of a novel web-based sleep apnea management platform.

Study Objective: Obstructive sleep apnea (OSA) is a highly prevalent yet underdiagnosed disorder affecting US military Veterans. The Remote Veterans Apnea Management Platform (REVAMP) is a web-based OSA management program created to improve access to care. REVAMP was launched within the Veterans Health Administration (VHA) in July 2017, with variable patient recruitment rates (from 0 to 573 patients per site) at the first 10 Veterans Affairs (VA) medical centers (Wave-1 sites).

The effects of depression on the treatment of OCD in a residential sample.

Studies investigating the impact of depressive symptoms on obsessive-compulsive disorder (OCD) treatment have yielded mixed findings. The purpose of the study is to extend previous research, which primarily used outpatient samples, to determine whether depression affects OCD treatment outcome among patients receiving intensive residential treatment. OCD patients receiving residential treatment based primarily on exposure and response prevention (ERP) provided data regarding symptoms of depression and OCD at admission and discharge.

Prevalence of Hoarding Behavior Among Formerly Homeless Persons Living in Supported Housing.

Hoarding disorder has become an official disorder in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5). Hoarding disorder affects approximately 1.5% to 5% of the general population, and there is no known literature that has examined the prevalence of hoarding disorder among homeless populations or those living in supported housing, although hoarding problems can jeopardize their housing situation.

Current drinking patterns in US veterans with a lifetime history of alcohol use disorder: Results from the National Health and Resilience in Veterans Study.

: Although more than 40% of US military veterans have lifetime histories of alcohol use disorder (AUD), little is known about the prevalence and correlates of current drinking patterns (i.e., abstinent, subthreshold, hazardous drinking) in this population.

A robust and reproducible connectome fingerprint of ketamine is highly associated with the connectomic signature of antidepressants.

Over the past decade, various N-methyl-D-aspartate modulators have failed in clinical trials, underscoring the challenges of developing novel rapid-acting antidepressants based solely on the receptor or regional targets of ketamine. Thus, identifying the effect of ketamine on the brain circuitry and networks is becoming increasingly critical. In this longitudinal functional magnetic resonance imaging study of data from 265 participants, we used a validated predictive model approach that allows the full assessment of brain functional connectivity, without the need for seed selection or connectivity summaries.

The effects of cognitive processing therapy + hypnosis on objective sleep quality in women with posttraumatic stress disorder.

Insomnia, characterized by difficulty falling and staying asleep, is a common and debilitating symptom of posttraumatic stress disorder (PTSD) that is resistant to first-line, trauma-focused therapies. Previous research has found that sleep-directed hypnosis improves subjective sleep quality, particularly sleep onset latency, in women with PTSD. However, it cannot be assumed that improvements in subjective sleep reports correspond with objectively measured sleep improvements, because research has indicated a lack of agreement across these measures.

Implementing Evidence-Based Pressure Injury Prevention Interventions: Veterans Health Administration Quality Improvement Collaborative.

Background: Pressure injury prevention is a persistent concern in nursing. The Veterans Health Administration implemented a creative approach with successful outcomes across the United States.

Problem: Pressure injury prevention is a measure of nursing quality of care and a high priority in the Veterans Health Administration.

Making connections: nationwide implementation of video telehealth tablets to address access barriers in veterans.

Background: Video telehealth technology has the potential to enhance access for patients with clinical, social, and geographic barriers to care. We evaluated the implementation of a US Department of Veterans Affairs (VA) initiative to distribute tablets to high-need Veterans with access barriers.

Methods: In this mixed methods implementation study, we examined tablet adoption (ie, facility-level tablet distribution rates and patient-level tablet utilization rates) and reach (ie, sociodemographic and clinical characteristics of tablet recipients) between 5/1/16 and 9/30/17.

Assessment of Health Information Technology-Related Outpatient Diagnostic Delays in the US Veterans Affairs Health Care System: A Qualitative Study of Aggregated Root Cause Analysis Data.

Importance: Diagnostic delay in the outpatient setting is an emerging safety priority that health information technology (HIT) should help address. However, diagnostic delays have persisted, and new safety concerns associated with the use of HIT have emerged.

Objective: To analyze HIT-related outpatient diagnostic delays within a large, integrated health care system.

Longitudinal Relationships between Perceived Social Support and Symptom Outcomes: Findings from a sample of Adult Survivors of Childhood Sexual Abuse.

Introduction: Cross-sectional studies have consistently reported an inverse association between perceived social support and the severity of mental health symptoms among adult survivors of childhood sexual abuse (CSA). However, there is a lack of longitudinal studies investigating the bidirectional association between social support and the severity of symptoms among adult CSA-survivors, as well as the role of relational problems in predicting perceived social support and symptom levels over time. The present study addressed these questions in a sample of primarily female CSA-survivors.

Discussing measurement-based care with patients: An analysis of clinician-patient dyads.

Measurement-based care (MBC) refers to the use of three integrated strategies to improve effectiveness of behavioral health care: routine outcomes monitoring using symptom measures; regularly sharing these data with patients; and using these data to inform treatment decisions. This study examined how clinicians discuss MBC data with patients, including identifying what aspects of these discussions contribute to clinician-patient agreement on the value of MBC, and how clinicians use MBC data to inform treatment decisions. Twenty-six clinician-patient dyads participated in semi-structured interviews and provided a treatment session recording in which MBC data were discussed.

Composite contributions of cerebrospinal fluid GABAergic neurosteroids, neuropeptide Y and interleukin-6 to PTSD symptom severity in men with PTSD.

Given that multiple neurobiological systems, as well as components within these systems are impacted by stress, and may interact in additive, compensatory and synergistic ways to promote or mitigate PTSD risk, severity, and recovery, we thought that it would be important to consider the , as well as separate effects of these neurobiological systems on PTSD risk. With this goal in mind, we conducted a proof-of-concept study utilizing cerebrospinal fluid (CSF) collected from unmedicated, tobacco- and illicit substance-free men with PTSD (n = 13) and trauma-exposed healthy controls (TC) (n = 17). Thirteen neurobiological factors thought to contribute to PTSD risk or severity based on previous studies were assayed.

Associations Between Social Anxiety and Affective and Empathic Forecasts: A Replication and Extension in a Mechanical Turk Sample.

People often overestimate the intensity and duration of their future emotions, referred to as an impact bias. Impact biases have been documented in predictions people make about their own emotions, as well as the others' emotions (i.e.

Mobile, Community-Based Buprenorphine Treatment for Veterans Experiencing Homelessness With Opioid Use Disorder: A Pilot, Feasibility Study.

Background And Objectives: Adults experiencing homelessness with opioid use disorder (OUD) utilize buprenorphine (BUP), a first-line medication for OUD, at very low rates. Innovative and tailored approaches are needed to reduce barriers to treatment and increase utilization of BUP in this population. This study describes a pilot Mobile Community-based Access Team (M-CAT) that used mobile technology and FaceTime in addition to existing community-based case management programs to provide BUP treatment for veterans with OUD experiencing homelessness who had difficulties engaging in the regular BUP clinic.

Dynamic interplay between PTSD symptoms and posttraumatic growth in older military veterans.

Background: Posttraumatic growth (PTG) refers to positive psychological changes that may occur after experiencing a traumatic event. While cross-sectional studies have suggested that posttraumatic stress disorder (PTSD) is associated with greater PTG, few longitudinal studies have evaluated interrelationships between PTSD and PTG. Further, little is known about which specific symptom clusters of PTSD and coping mechanisms may drive PTG over time.

Checklist design and implementation: critical considerations to improve patient safety for low-frequency, high-risk patient events.

Purpose: This pilot project describes the development and implementation of two specialised aviation-style checklist designs for a low-frequency high-risk patient population in a cardiac intensive care unit. The effect of the checklist design as well as the implementation strategies on patient outcomes and adherence to best practice guidelines were also explored. The long-term objective was to improve adherence to accepted processes of care by establishing the checklists as standard practice thereby improving patient safety and outcomes.

"Doc, I'm Going for a Walk": Liberalizing or Restricting the Movement of Hospitalized Patients-Ethical, Legal, and Clinical Considerations.

When patients are admitted to the hospital, they are generally expected to remain in or within close proximity to their assigned rooms in order to promote their safety and appropriate medical care. Although there are circumstances when patients may safely leave their hospital room or floor, guidance within the medical literature for the management of patient movement within the hospital are lacking. Excessive restrictions on patient movement may be seen as overly paternalistic, while lax requirements may interfere with high quality care, patient safety and efficient hospital practice.

The Affective Control Scale: Factor structure and associations with posttraumatic stress symptoms in trauma-exposed male veterans.

Objective: Posttraumatic stress disorder (PTSD) is characterized by broad-based difficulties with emotion. However, the extent to which the disorder is associated with fear of particular emotions remains less well understood. The Affective Control Scale (ACS) is a frequently used measure of fear of emotion, but relatively little work has been done to validate this measure, particularly for use in psychiatric research.
