Characterizing Individuals Who Elect and Decline Opioid Overdose Education and Naloxone Distribution to Tailor Programs and Expand Impact.

Background: In response to the opioid epidemic, federal agencies have stressed the importance of targeted naloxone distribution through avenues such as Opioid Overdose Education and Naloxone Distribution (OEND). OEND effectively reduces mortality by training laypersons to respond to overdose situations. Despite demonstrated effectiveness, OEND remains underutilized.

Understanding the relationship between childhood abuse and affective symptoms in bipolar disorder: New insights from a network analysis.

The impact of childhood abuse on the presentation of bipolar disorder could be further elucidated by comparing the networks of affective symptoms among individuals with and with no history of childhood abuse. Data from 476 participants in the Clinical Health Outcomes Initiative in Comparative Effectiveness for Bipolar Disorder study were used to fit several regularised Gaussian Graphical Models. Differences in the presentation of depressive and manic symptoms were uncovered: only among participants with a history of childhood abuse, inadequacy and pessimism were central symptoms in the network of depressive symptoms, while racing thoughts was an important symptom in the network of manic symptoms.

Comparative effectiveness research trial for antidepressant incomplete and non-responders with treatment resistant depression (ASCERTAIN-TRD) a randomized clinical trial.

Further research is needed to help improve both the standard of care and the outcome for patients with treatment-resistant depression. A particularly critical evidence gap exists with respect to whether pharmacological or non-pharmacological augmentation is superior to antidepressant switch, or vice-versa. The objective of this study was to compare the effectiveness of augmentation with aripiprazole or repetitive transcranial magnetic stimulation versus switching to the antidepressant venlafaxine XR (or duloxetine for those not eligible to receive venlafaxine) for treatment-resistant depression.

Impact of Nicotine Replacement Therapy Sampling on Cessation-Related Processes.

Objectives: Smoking prevalence remains high among low-income smokers. Understanding processes (eg, withdrawal, craving, motivation) in early smoking cessation is crucially important for designing effective interventions for this population.

Methods: This is a secondary analysis of a novel, in-session sampling intervention (ie, In Vivo) as compared with standard care behavioral smoking cessation counseling (SC) among community-dwelling low-income smokers (n = 83).

Preliminary effectiveness of online opioid overdose and naloxone administration training and impact of naloxone possession on opioid use.

Background: Despite the demonstrated value of opioid overdose education and naloxone distribution (OEND) programs, uptake and utilization remains low. Accessibility to OEND is limited and traditional programs may not reach many high-risk individuals. This study evaluated the effectiveness of online opioid overdose and naloxone administration education and the impact of naloxone possession.

Feasibility and acceptability of online opioid overdose education and naloxone distribution: Study protocol and preliminary results from a randomized pilot clinical trial.

Unlabelled: Drug overdose is the leading cause of accidental death in the United States, with over 70% of drug related fatalities resulting from the use of opioids. Federal agencies have responded to this crisis with various recommendations including enhancing harm reduction approaches such as training laypersons to administer naloxone through Opioid Overdose Education and Naloxone Distribution (OEND) programs. Several studies have demonstrated that OEND programs effectively reduce opioid overdose mortality and are both safe and cost-effective, however, they are typically implemented in urban areas as part of large medical center research programs, needle exchanges, or drug treatment programs.

Genomics in Treatment Development.

The Human Genome Project mapped the 3 billion base pairs in the human genome, which ushered in a new generation of genomically focused treatment development. While this has been very successful in other areas, neuroscience has been largely devoid of such developments. This is in large part because there are very few neurological or mental health conditions that are related to single-gene variants.

The effect of IV ketamine in patients with major depressive disorder and elevated features of borderline personality disorder.

Background: Comorbid borderline personality disorder and major depressive disorder is common and often not adequately responsive to standard antidepressant therapies. Ketamine is a potentially life-saving option.

Methods: 153 adult patients with MDD were assessed with the Personality Assessment Inventory (PAI) Borderline Subscale.

Childhood trauma and treatment outcomes during mood-stabilising treatment with lithium or quetiapine among outpatients with bipolar disorder.

Background: Childhood trauma affects the course of mood disorders. Researchers are now considering childhood trauma as an influential factor in the treatment of mood disorders. However, the role of childhood trauma in the treatment of bipolar disorder remains understudied.

Combinatorial pharmacogenomic algorithm is predictive of sertraline metabolism in patients with major depressive disorder.

Pharmacogenomic testing can be used to guide medication selection in patients with major depressive disorder (MDD). Currently, there is no consensus on which gene or genes to consider in medication management. Here, we assessed the clinical validity of the combinatorial pharmacogenomic algorithm to predict sertraline blood levels in a subset of patients enrolled in the Genomics Used to Improve DEpression Decisions (GUIDED) trial.

Cardiometabolic risk markers during mood-stabilizing treatment: Correlation with drug-specific effects, depressive symptoms and treatment response.

Background: Patients with bipolar disorder have higher rates of cardiometabolic comorbidities and mortality. Although guidelines emphasize the importance of cardiovascular monitoring, few studies characterized the cardiometabolic risk profile during treatment and their relation to symptomatology and treatment response.

Methods: We analyzed data from two similar 24-weeks comparative effectiveness trials, with a combined sample of 770 participants randomized to two different lithium doses, quetiapine (300 mg/day), or standard treatment without lithium.

A Delphi-method-based consensus guideline for definition of treatment-resistant depression for clinical trials.

Criteria for treatment-resistant depression (TRD) and partially responsive depression (PRD) as subtypes of major depressive disorder (MDD) are not unequivocally defined. In the present document we used a Delphi-method-based consensus approach to define TRD and PRD and to serve as operational criteria for future clinical studies, especially if conducted for regulatory purposes. We reviewed the literature and brought together a group of international experts (including clinicians, academics, researchers, employees of pharmaceutical companies, regulatory bodies representatives, and one person with lived experience) to evaluate the state-of-the-art and main controversies regarding the current classification.

Obesogenic Medications and Weight Gain Over 24 Weeks in Patients with Depression: Results from the GUIDED Study.

Weight gain is a common side-effect of medications used to treat major depressive disorder (MDD). We sought to estimate the frequency of weight gain for obesogenic medications prescribed for MDD and to evaluate if bupropion mitigated risk for weight gain. We analyzed a prospective cohort of patients with weight available at baseline and 12 weeks (n = 1,032) or 24 weeks (n = 871) in a post hoc analysis of the enomics sed to mprove pression ecisions (GUIDED) study of patients with MDD who failed at least one medication trial.

Response and remission rates during 24 weeks of mood-stabilizing treatment for bipolar depression depending on early non-response.

Background: We aimed to study the probability of bipolar depression response at 24 weeks given initial non-response.

Methods: We combined two multi-site, 24-week trials including similar populations following the same evidence-based guidelines randomizing patients to lithium or quetiapine. Additional mood-stabilizing treatment was possible if clinically indicated.

Illness stage and predominant polarity in bipolar disorder: Correlation with burden of illness and moderation of treatment outcome.

Bipolar disorder often follows a set progression best described in stages where advanced stages are associated with poorer outcomes. Bipolar disorder is also often characterized by a predominance of episode polarity, where some individuals experience more depressive episodes (termed predominant depressive polarity) while others experience more hypo/manic episodes (termed predominant hypo/manic polarity). We examined the associations between staging and predominant polarity with measures of illness burden and treatment outcome utilizing data from a six-month comparative effectiveness trial of lithium and quetiapine in bipolar disorder (Bipolar CHOICE).

A Pilot Study of Nicotine Replacement Therapy Sampling and Selection to Increase Medication Adherence in Low-Income Smokers.

Introduction: Adherence to smoking cessation medications remains suboptimal, particularly among low-income smokers. Guided, experiential sampling of nicotine replacement therapies (NRTs) may increase NRT adherence and smoking cessation over gold standard counseling plus NRT. The present pilot study aimed to examine feasibility, acceptability, and preliminary efficacy of a novel experiential intervention.

Effect of Adjunctive Pimavanserin on Sleep/Wakefulness in Patients With Major Depressive Disorder: Secondary Analysis From CLARITY.

Objective: This was an analysis of the effect of pimavanserin, a 5-hydroxytryptamine-2A antagonist and inverse receptor agonist, on dysregulated sleep in patients with major depressive disorder (MDD) by DSM-5 criteria and an inadequate antidepressant response.

Methods: For this analysis of CLARITY, a phase 2 study of adjunctive pimavanserin (N = 207) conducted between December 2016 and October 2018, sleep/wakefulness disturbances were measured with the 17-item Hamilton Depression Rating Scale (HDRS₁₇) insomnia items (sum of items 4, 5, and 6) and the Karolinska Sleepiness Scale (KSS). Outcomes included change from baseline in HDRS₁₇ insomnia factor score and KSS score, correlation between the HDRS₁₇ insomnia factor score and KSS score, and change from baseline in the Sheehan Disability Scale (SDS) total score and Unproductive Days subscore in patients with a baseline KSS score ≥ 6.

Effect of pimavanserin on anxious depression in patients with major depression and an inadequate response to previous therapy: secondary analysis of the clarity study.

In a post hoc analysis, the effect of pimavanserin on anxious depression was determined from CLARITY, a randomized, double-blind, placebo-controlled study in patients with major depression and an inadequate response to previous therapy. Patients were randomized in a 3:1 ratio to placebo or pimavanserin 34 mg daily added to ongoing antidepressant therapy. At 5 weeks, placebo nonresponders were rerandomized to placebo or pimavanserin for an additional 5 weeks.
