SKA2 enhances stress-related glucocorticoid receptor signaling through FKBP4-FKBP5 interactions in neurons.

Genes involved in regulating the hypothalamic-pituitary-adrenal (HPA) axis, including the glucocorticoid receptor (GR), are linked to various stress-related psychopathologies including bipolar disorder as well as other mood and trauma-related disorders. The protein product of the cell cycle gene, is a GR interaction partner in peripheral cells. However, the precise roles of SKA2 in stress and GR signaling in the brain, specifically in nonreplicating postmitotic neurons, and its involvement in HPA axis regulation remain unclear.

Longitudinal Course of Physical and Psychosocial Impairment in Patients With Borderline Personality Disorder and Personality-Disordered Comparison Subjects: Description and Prediction.

This study describes the 8-year course of physical and psychosocial impairment in middle-aged patients with borderline personality disorder (BPD) and other personality disorders (OPD). This study also compares BPD subgroups (recovered vs. nonrecovered) and explores predictors of physical impairment.

Differential Mapping of Psychopathic Traits and General Psychopathology in a Large Young Adult Sample.

Psychopathy is a personality disorder characterized by affective-interpersonal features and an impulsive-antisocial lifestyle. Psychopathy commonly co-occurs with other forms of psychopathology, but current understanding of how behavioral features of psychopathy co-occur with, or are distinct from, other mental health problems is limited. In this study, we analysed data from a large sample of young adults to study the relationship between different facets of psychopathic traits and general psychopathology ("p").

Deep transcranial magnetic stimulation for adolescents with treatment-resistant depression: Behavioral and neural correlates of clinical improvement.

Background: Affective bias toward negativity is associated with depression and may represent a promising treatment target. Stimulating the dorsolateral prefrontal cortex (dlPFC) with deep Transcranial Magnetic Stimulation (dTMS) could lead to shifts in affective bias. The current study examined behavioral and neural correlates of affective bias in the context of dTMS in adolescents with treatment-resistant depression (TRD).

Dementia with lewy bodies patients with high tau levels display unique proteome profiles.

Background: Clinical studies have long observed that neurodegenerative disorders display a range of symptoms and pathological features and, in some cases, overlap, suggesting that these diseases exist on a spectrum. Dementia with Lewy Bodies (DLB), a synucleinopathy, is a prominent example, where symptomatic similarities with tauopathy, Alzheimer's disease, are observed. Although tau pathology has been observed in DLB, the interplay between tau and α-synuclein is poorly understood at a molecular level.

M1 recruitment during interleaved practice is important for encoding, not just consolidation, of skill memory.

The primary motor cortex (M1) is crucial for motor skill learning. We examined its role in interleaved practice, which enhances retention (vs. repetitive practice) through M1-dependent consolidation.

Trauma-related moderators of associations between sex hormones and PTSD symptoms: a replication-extension.

Post-traumatic stress disorder (PTSD) disproportionately affects women and recent evidence suggests that unique associations between sex hormones (e.g. estradiol and progesterone) and PTSD symptoms may contribute to this difference.

Implications of the choroid plexus in Niemann-Pick disease Type C neuropathogenesis.

Background: Niemann-Pick Disease Type C (NPC) is an ultra-rare disorder characterized by progressive psychiatric and neurologic manifestations, with late infantile, juvenile, and adolescent/adult presentations. We examined morphological properties of the choroid plexus, a protective blood-cerebrospinal fluid barrier, in NPC, and their relationship with neurodegeneration, clinical status, and circulatory markers. This study also determined whether choroid plexus morphology differentiates between NPC and more prevalent illnesses, schizophrenia (SZ) and bipolar disorder (BD), which have overlapping psychiatric symptoms with adolescent and adult-onset NPC and are associated with misdiagnosis.

Biomarker discovery using machine learning in the psychosis spectrum.

The past decade witnessed substantial discoveries related to the psychosis spectrum. Many of these discoveries resulted from pursuits of objective and quantifiable biomarkers in tandem with the application of analytical tools such as machine learning. These approaches provided exciting new insights that significantly helped improve precision in diagnosis, prognosis, and treatment.

Review of Emotion Regulation in Late Life Mood Disorders.

Emotion regulation (ER), or the ability to modulate the experience and expression of emotion, is critical to adaptive functioning and is a key feature of mood disorders. At the same time, normal aging is associated with changes in ER, though the interaction of aging with the presence of a mood disorder are unclear. Here, we review what is known about ER and its underlying neural mechanisms in late life mood disorders, specifically late life depression and bipolar disorder.

A Prospective Open-Label Trial of Buspirone for the Treatment of Anxiety in Williams Syndrome.

Prospective open-label trial. The objective of this study was to determine whether buspirone showed preliminary evidence of effectiveness, safety, and tolerability in individuals with Williams syndrome (WS). This is a 16-week, prospective, flexibly dosed, open-label trial of buspirone in 20 individuals with WS aged 5-65 years.

Addressing Spiritual and Religious Experiences in Borderline Personality Disorder With Good Psychiatric Management.

Spiritual and religious experiences in the context of borderline personality disorder are underexplored by both researchers and clinicians, are central in the lived experience of some patients, and are likely to interact in complex ways with core symptoms and challenges. Effective navigation of this domain by clinicians and patients may require increasing, decreasing, or stabilizing engagement with spiritual and religious beliefs, practices, or communities, depending on the person. No empirically derived guidelines exist for how clinicians can address this area to help patients maximize benefits while minimizing harms.

Peritraumatic C-reactive protein levels predict pain outcomes following traumatic stress exposure in a sex-dependent manner.

Background: Chronic pain following traumatic stress exposure (TSE) is common. Increasing evidence suggests inflammatory/immune mechanisms are induced by TSE, play a key role in the recovery process versus development of post-TSE chronic pain, and are sex specific. In this study, we tested the hypothesis that the inflammatory marker C-reactive protein (CRP) is associated with chronic pain after TSE in a sex-specific manner.

Aspirin guided by coronary artery calcium scoring for primary cardiovascular prevention in persons with subclinical coronary atherosclerosis.

Although endurance exercise is cardioprotective, episodes of strenuous physical exertion can trigger sudden cardiac death. While marathon training promotes overall heart health, running such races transiently increases cardiac arrest risk, mainly in middle-aged men with subclinical coronary atherosclerosis. Coronary artery calcium scanning has been advised for risk stratification to identify those who benefit from enhanced primary prevention.

Catecholaminergic Modulation of Large-Scale Network Dynamics Is Tied to the Reconfiguration of Corticostriatal Connectivity.

Large-scale brain network function is critical for healthy cognition, yet links between such network function, neurochemistry, and smaller-scale neurocircuitry are unclear. Here, we evaluated 59 healthy individuals using resting-state fMRI to determine how network-level temporal dynamics were impacted by two well-characterized pharmacotherapies targeting catecholamines: methylphenidate (20 mg) and haloperidol (2 mg)-administered via randomized, double-blind, placebo-controlled design. Network temporal dynamic changes were tested for links with drug-induced alterations in complex corticostriatal connections as this circuit is a primary site of action for both drugs.

Affective temperaments: Effects on treatment response for major depression.

There is growing interest in assessing affective temperaments in relation to major depressive disorder (MDD) and bipolar disorder (BD). Needed is evaluation of the impact of temperament ratings on responses to treatment of depression in these disorders. We measured treatment response as %-improvement in HDRS depression ratings and correlated this measure as well as response rate (≥50 % improvement) with TEMPS-A ratings of anxious, cyclothymic, dysthymic, hyperthymic, and irritable affective temperaments in 2264 mood-disorder patients (1165 BD, 1099 MDD; 62.

Uncovering Key Predictive Channels and Clinical Variables in the Gamma Band Auditory Steady-State Response in Early Stage Psychosis - a Longitudinal Study.

Objective: Psychotic disorders are characterized by abnormalities in the synchronization of neuronal responses. A 40 Hz gamma band deficit during auditory steady-state response (ASSR) measured by electroencephalogram (EEG) is a robust observation in psychosis and is associated with symptoms and functional deficits. However, the majority of ASSR studies focus on specific electrode sites, while whole scalp analysis using all channels, and the association with clinical symptoms, are rare.

REM disruption and REM vagal activity predict extinction recall in trauma-exposed individuals.

Background: Accumulating evidence suggests that rapid eye movement sleep (REM) supports the consolidation of extinction memory. REM is disrupted in posttraumatic stress disorder (PTSD), and REM abnormalities after traumatic events increase the risk of developing PTSD. Therefore, it was hypothesized that abnormal REM in trauma-exposed individuals may pave the way for PTSD by interfering with the processing of extinction memory.

Patient-Centered Communication: Incorporating Principles of Dialogic Practice and Family Centered Rounds on an Inpatient Psychotic Disorders Unit.

This study examined the impact of Patient-Centered Communication (PCC), Open Dialogue-inspired changes to rounding practices and culture, on patient perceptions of care on an inpatient psychotic disorders unit. A retrospective cohort analysis was conducted based on medical records, restraint and seclusion records, and hospital Perceptions of Care (PoC) surveys. The analysis compared data from 6-month periods before and after implementation of PCC to quantify whether the implementation of PCC was associated with more positive care ratings.

Kratom: A Narrative Review of the Possible Clinical Uses and Dangers of This Opioid-Like Plant.

The term "kratom" refers to a plant species formally known as  Kratom is composed of over 40 alkaloids, a type of organic compound that contains nitrogen. These compounds work primarily via binding to opioid receptors expressed on neurons, where they stimulate signal transduction mechanisms involving the activation of G proteins. Kratom has been shown to cause both a stimulant-like effect and a sedative effect in humans.

Study protocol for a pilot randomised controlled trial of a virtually delivered behavioural intervention (ACTION) for adults with cancer at risk for opioid use disorder.

Introduction: Opioid therapy is often central to pain management during cancer care. However, opioid exposure and unaddressed psychological suffering jointly amplify opioid use disorder risk. Therefore, we iteratively developed a behavioural, individually delivered intervention to mitigate the risk of opioid use disorder during cancer care (Acceptance and Commitment Therapy Intervention when Opioids are Necessary (ACTION)).
