Functional and structural brain network correlates of visual hallucinations in Lewy body dementia.

Visual hallucinations are a common feature of Lewy body dementia. Previous studies have shown that visual hallucinations are highly specific in differentiating Lewy body dementia from Alzheimer's disease dementia and Alzheimer-Lewy body mixed pathology cases. Computational models propose that impairment of visual and attentional networks is aetiologically key to the manifestation of visual hallucinations symptomatology.

Do early responders and treatment non-responders offer guidance to make CPT group a more effective treatment?

Background: Treatment dropout has been problematic with evidence-based treatments for posttraumatic stress disorder (PTSD), including cognitive processing therapy (CPT). This study sought to evaluate whether CPT group contributed to symptom improvement among treatment completers and non-completers.

Methods: Sixty-one Iraq and Afghanistan combat Veterans self-selected CPT group or treatment as usual (TAU) forming a convenience sample.

Identification of an optimal dose of intravenous ketamine for late-life treatment-resistant depression: a Bayesian adaptive randomization trial.

Evidence supporting specific therapies for late-life treatment-resistant depression (LL-TRD) is necessary. This study used Bayesian adaptive randomization to determine the optimal dose for the probability of treatment response (≥50% improvement from baseline on the Montgomery-Åsberg Depression Rating Scale) 7 days after a 40 min intravenous (IV) infusion of ketamine 0.1 mg/kg (KET 0.

Using the Psychiatry Resident-In-Training Examination (PRITE) to Assess the Psychiatry Medical Knowledge Milestones in Psychiatry.

Objective: The introduction of the Milestone Project underscored the need for objective assessments of resident progress across the competencies. Therefore, the authors examined the Psychiatry Resident-In-Training Examination (PRITE) utility for measuring improvements in medical knowledge (MK).

Methods: The authors compared the mean performance for each MK subcompetency by resident year for all residents taking the PRITE from 2015 to 2017 (18,175 examination administrations).

Neurophysiological and clinical effects of the NMDA receptor antagonist lanicemine (BHV-5500) in PTSD: A randomized, double-blind, placebo-controlled trial.

Background: Posttraumatic stress disorder (PTSD) is associated with hyperarousal and stress reactivity, features consistent with behavioral sensitization. In this Phase 1b, parallel-arm, randomized, double-blind, placebo-controlled trial, we tested whether the selective low-trapping N-methyl-D-aspartate receptor (NMDAR) antagonist [Lanicemine (BHV-5500)] blocks expression of behavioral sensitization.

Methods: Twenty-four participants with elevated anxiety potentiated startle (APS) and moderate-to-severe PTSD symptoms received three infusions of lanicemine 1.

Crisis Preparedness in Acute and Intensive Treatment Settings: Lessons Learned From a Year of COVID-19.

The impact of COVID-19 changed the use and delivery of health care services, requiring an abrupt shift in treatment and staffing models . This is particularly salient in youth acute and intensive treatment services (AITS), including inpatient psychiatric hospitals (IPH), intensive outpatient programs (IOP), and partial hospitalization programs (PHP), because of challenging issues of maintaining high-quality care and a safe therapeutic milieu during increased demand for acute services, all while limiting transmission of COVID-19 on locked units, in close quarters, and for youths traveling back and forth to day-programs. Over the past year, AITS adapted and evolved without the ability to pause services and plan, increase staffing, or allocate additional resources.

Reward Processing in Psychiatric Inpatients With Depression.

Background: Previous neuroimaging studies have investigated reward-processing dysfunction in major depressive disorder and have led to the common finding that major depressive disorder is associated with reduced reward responses within the reward circuit. Yet it is unclear whether such reward-processing dysfunction is specifically associated with the severity of depressive symptoms in major depressive disorder or is associated with common comorbidities.

Methods: We investigated reward-processing differences using a classic juice-delivery functional magnetic resonance imaging experiment to compare psychiatric patients with severe depressive symptoms (DEPs) to both psychiatric control subjects (PCs) and healthy control subjects.

Smoking status links habenular volume to glycated hemoglobin: Findings from the Human Connectome Project-Young Adult.

Background: The habenula-pancreas axis regulates the stimulatory effects of nicotine on blood glucose levels and may participate in the emergence of type 2 diabetes in human tobacco smokers. This secondary analysis of young adults from the Human Connectome Project (HCP-YA) evaluated whether smoking status links the relationship between habenular volume and glycated hemoglobin (HbA1c), a marker of long-term glycemic control.

Methods: Habenula segmentation was performed using a fully-automated myelin content-based approach in HCP-YA participants and the results were inspected visually (n = 693; aged 22-37 years).

Types of Learners.

There is a robust literature on learning styles. This literature rests on 3 assumptions: (1) Individuals have a preference for a particular style of learning, (2) Individuals learn better using their preferred style, and (3) Teachers should adjust their teaching to accommodate their learner's style. One benefit of understanding learning styles is to encourage in-depth learning.

The OPRD1 rs678849 variant influences outcome of disulfiram treatment for cocaine dependency in methadone-maintained patients.

Objective: Prior research demonstrated that the δ-opioid receptor (OPRD1) rs678849 variant influences opioid use in African Americans treated with methadone. We examined whether this variant moderated cocaine and opioid use in our clinical cohort of methadone and disulfiram treated recipients.

Methods: Cocaine and opioid codependent patients were stabilized for 2 weeks on methadone and subsequently randomized into groups treated with either methadone + placebo (n = 37) or methadone + disulfiram (250 mg/day; n = 33) for 12 weeks.

A systematic review of mHealth application interventions for peripartum mood disorders: trends and evidence in academia and industry.

In this review, we aim to summarize research findings and marketplace apps for women with perinatal mood disorders with the goal of informing clinicians and patients about current risks and benefits, as well as proposing clinical implementation advice and a harmonized agenda for both academic and industry advancement in this space. Multiple searches were run of academic databases in 2018-2020, examining literature on mobile apps for peripartum mental health. Multiple searches were also run of the iOS and Android app stores in 2019 and 2020, looking at apps for peripartum mental health.

Evolution of genetic networks for human creativity.

The genetic basis for the emergence of creativity in modern humans remains a mystery despite sequencing the genomes of chimpanzees and Neanderthals, our closest hominid relatives. Data-driven methods allowed us to uncover networks of genes distinguishing the three major systems of modern human personality and adaptability: emotional reactivity, self-control, and self-awareness. Now we have identified which of these genes are present in chimpanzees and Neanderthals.

Does mismatch negativity have utility for NMDA receptor drug development in depression?

Rapid antidepressant effects associated with ketamine have shifted the landscape for the development of therapeutics to treat major depressive disorder (MDD) from a monoaminergic to glutamatergic model. Treatment with ketamine, an N-methyl-D-aspartate (NMDA) receptor antagonist, may be effective, but has many non-glutamatergic targets, and clinical and logistical problems are potential challenges. These factors underscore the importance of manipulations of binding mechanics to produce antidepressant effects without concomitant clinical side effects.

Distinct trajectories of antidepressant response to intravenous ketamine.

Background: The N-methyl-D-aspartate receptor antagonist ketamine is potentially effective in treatment resistant depression. However, its antidepressant efficacy is highly variable, and there is little information about predictors of response.

Methods: We employed growth mixture modeling (GMM) analysis to examine specific response trajectories to intravenous (IV) ketamine (three infusions; mean dose 0.
