Sex-specific behavioral and thalamo-accumbal circuit adaptations after oxycodone abstinence.

Opioid use disorder is marked by a progressive change in the motivation to administer the drug even in the presence of negative consequences. After long periods of abstinence, the urge to return to taking the drug intensifies over time, known as incubation of craving. Conditioned responses to drug-related stimuli, can acquire motivational properties and exert control over motivated behaviors leading to relapse.

The emergence of antidepressant drugs targeting GABA receptors: A concise review.

Depression is among the most common psychiatric illnesses, which imposes a major socioeconomic burden on patients, caregivers, and the public health system. Treatment with classical antidepressants (e.g.

The 24-Year Course of Symptomatic Disorders in Patients With Borderline Personality Disorder and Personality-Disordered Comparison Subjects: Description and Prediction of Recovery From BPD.

Our first objective was to compare the prevalence of symptomatic disorders (formerly Axis I disorders) over 24 years of prospective follow-up among patients with borderline personality disorder (BPD) and other personality disordered comparison subjects as well as recovered vs nonrecovered borderline patients. Our second objective was to assess the relationship between the absence of 5 major classes of symptomatic disorders over time and the likelihood of concurrent recovery among borderline patients. The McLean Study of Adult Development (MSAD) is a naturalistic prospective follow-up study of 362 inpatients assessed at 12 contiguous 2-year follow-up waves.

Comparative Safety of In Utero Exposure to Buprenorphine Combined With Naloxone vs Buprenorphine Alone.

Importance: Buprenorphine combined with naloxone is commonly used to treat opioid use disorders outside of pregnancy. In pregnancy, buprenorphine alone is generally recommended because of limited perinatal safety data on the combination product.

Objective: To compare perinatal outcomes following prenatal exposure to buprenorphine with naloxone vs buprenorphine alone.

Widespread Autonomic Physiological Coupling Across the Brain-Body Axis.

The brain is closely attuned to visceral signals from the body's internal environment, as evidenced by the numerous associations between neural, hemodynamic, and peripheral physiological signals. We show that these brain-body co-fluctuations can be captured by a single spatiotemporal pattern. Across several independent samples, as well as single-echo and multi-echo fMRI data acquisition sequences, we identify widespread co-fluctuations in the low-frequency range (0.

Effects of chronic naltrexone treatment on relapse-related behavior and neural responses to fentanyl in awake nonhuman primates.

Naltrexone, an opioid antagonist that blocks the reinforcing properties of opioid agonists, is often prescribed to preclude relapse to opioid use disorder (OUD) following detoxification. However, few laboratory studies have directly investigated the ability of naltrexone to alter relapse-inducing effects of opioid agonists, including their priming strength in reinstatement studies and their impact in brain regions known to be involved in drug-induced reinforcement in MRI studies. Here we directly address this issue by investigating the effects of continuous exposure to naltrexone on 1) fentanyl-induced reinstatement of drug-seeking behavior, 2) fentanyl-induced patterns of blood oxygenation level dependent (BOLD) activation in the nucleus accumbens (NAcc), and 3) fentanyl-induced changes in NAcc functional connectivity (FC) in awake non-human primates that are engaged in ongoing opioid self-administration studies.

Trauma Prevalence and Its Association With Health-Related Quality of Life in Pregnant Persons with Opioid Use Disorder.

Objectives: Trauma screening is recommended for pregnant persons with opioid use disorder (OUD), but there is limited literature on screening results from buprenorphine treatment. This study's objectives were to 1) describe the types, and severity, of traumatic events reported and 2) evaluate the associations between trauma and health-related quality of life (HRQoL).

Methods: Baseline data from an ongoing trial were analyzed.

Racial and ethnic differences in self-reported barriers to substance use treatment among emergency department patients.

Background And Objectives: As overdose rates rise among non-White Americans, understanding barriers to substance use disorder (SUD) treatment access by race and ethnicity is important. This study explores self-reported barriers to SUD treatment by race and ethnicity in emergency department (ED) populations.

Methods: We conducted a secondary, exploratory analysis of a randomized trial of patients not seeking SUD treatment who endorsed active drug use at six academic EDs.

Insomnia in Parkinson's Disease: Causes, Consequences, and Therapeutic Approaches.

Sleep disorders represent prevalent non-motor symptoms in Parkinson's disease (PD), affecting over 90% of the PD population. Insomnia, characterized by difficulties in initiating and maintaining sleep, emerges as the most frequently reported sleep disorder in PD, with prevalence rates reported from 27 to 80% across studies. Insomnia not only significantly impacts the quality of life of PD patients but is also associated with cognitive impairment, motor disabilities, and emotional deterioration.

Translation of monosynaptic circuits underlying amygdala fMRI neurofeedback training.

fMRI neurofeedback using autobiographical memory recall to upregulate the amygdala is associated with resting-state functional connectivity (rsFC) changes between the amygdala and the salience and default mode networks (SN and DMN, respectively). We hypothesize the existence of anatomical circuits underlying these rsFC changes. Using a cross-species brain parcellation, we identified in non-human primates locations homologous to the regions of interest (ROIs) from studies showing pre-to-post-neurofeedback changes in rsFC with the left amygdala.

Age and gender differences in motives for z-drug misuse: Findings from the 2015 to 2019 NSDUH survey.

Background And Objectives: Approximately 9% of people who are exposed to a nonbenzodiazepine sedative-hypnotic medication ("z-drug") misuse this medication, yet, the reasons why people misuse z-drugs are not well-characterized.

Methods: Using population survey data, we examined gender and age differences in motives for z-drug misuse.

Results: Results suggested women and older adults have higher odds of misusing z-drugs for sleep, and young adults have higher odds of misusing for recreation.

The Human Connectome Project of adolescent anxiety and depression dataset.

This article describes primary data and resources available from the Boston Adolescent Neuroimaging of Depression and Anxiety (BANDA) study, a novel arm of the Human Connectome Project (HCP). Data were collected from 215 adolescents (14-17 years old), 152 of whom had current diagnoses of anxiety and/or depressive disorders at study intake. Data include cross-sectional structural (T1- and T2-weighted), functional (resting state and three tasks), and diffusion-weighted magnetic resonance images.

Course and Prediction of Dissociation in Patients with Borderline Personality Disorder and Personality-Disordered Comparison Subjects: A 24-Year Follow-Up Study.

The first purpose of this study was to determine the course of dissociation among patients with borderline personality disorder (BPD) and personality-disordered comparison subjects (OPD) over 24 years of prospective follow-up. The second purpose was to determine clinically meaningful predictors of dissociation among patients with BPD. The Dissociative Experiences Scale (DES) was administered to 290 patients with BPD and 72 personality-disordered comparison subjects at baseline, and then once every two years over 24 years of prospective follow-up.

Acceptability and Engagement of a Smartphone-Delivered Interpretation Bias Intervention in a Sample of Black and Latinx Adults: Open Trial.

Background: Access to evidence-based interventions is urgently required, especially for individuals of minoritized identities who experience unique barriers to mental health care. Digital mental health interventions have the potential to increase accessibility. Previous pilot studies testing HabitWorks, a smartphone app providing an interpretation bias intervention, have found strong engagement and adherence for HabitWorks; however, previous trials' samples consisted of predominantly non-Hispanic, White individuals.

Neighborhood Resources Associated With Psychological Trajectories and Neural Reactivity to Reward After Trauma.

Importance: Research on resilience after trauma has often focused on individual-level factors (eg, ability to cope with adversity) and overlooked influential neighborhood-level factors that may help mitigate the development of posttraumatic stress disorder (PTSD).

Objective: To investigate whether an interaction between residential greenspace and self-reported individual resources was associated with a resilient PTSD trajectory (ie, low/no symptoms) and to test if the association between greenspace and PTSD trajectory was mediated by neural reactivity to reward.

Design, Setting, And Participants: As part of a longitudinal cohort study, trauma survivors were recruited from emergency departments across the US.

General Psychiatric Management for Adolescents With Borderline Personality Disorder and Eating Disorders.

Borderline personality disorder and eating disorders frequently co-occur among youths. These disorders emerge in adolescence, during the critical developmental period of building an independent sense of self and the capacity to relate to one's community. Because of core differences in the development and psychopathology of borderline personality disorder and eating disorders, adjustments are required when treating these disorders when they co-occur.

Towards predicting PTSD symptom severity using portable EEG-derived biomarkers.

Posttraumatic Stress Disorder (PTSD) is a heterogeneous mental health disorder that occurs following traumatic experience. Understanding its neurobiological basis is crucial to advance early diagnosis and treatment. Electroencephalography (EEG) can be used to explore the neurobiological basis of PTSD.

Psychoeducation for Pathologic Narcissism and Narcissistic Personality Disorder: A Review and Proposal for a Good Psychiatric Management-based Six-week Group Program.

Pathologic narcissism (PN) and narcissistic personality disorder (NPD) are 2 common and stigmatized clinical constructs that are known to have large consequences for patients' functioning and mental health-related outcomes. To date, no treatment for these conditions has been empirically validated, but there is a relative consensus about the importance of psychoeducation. Here we present a model for a psychoeducational intervention for patients with PN or NPD.

The relationship between personality and cognition in older adults with and without early-onset depression.

Introduction: It is well established that personality traits impact cognition, as certain personality factors are associated with performance in specific cognitive domains. However, the findings on the relationships between the Big Five traits and cognition are mixed. Additionally, few studies have explored these relationships in older adults with a history of depression.
