AIMS: The nerve growth factor (NGF) and the vascular endothelial growth factor-A (VEGF-A) may be of importance for psychiatric diseases including substance use disorders. The aim of the study was to identify differences in the regulation of both neuropeptides via the DNA-methylation status of the promotor regions of NGF and VEGF-A in different forms of maintenance therapy for opioid dependence and the related stress regulation via the hypothalamic-pituitary-adrenal axis. METHODS: We compared methylation levels of opioid-dependent patients receiving treatment with diamorphine (n = 28) or levomethadone (n = 54) and similar levels in a healthy control group (n = 72)...

Heart rate variability (HRV) in psychiatric disorders has become an increasing area of interest in recent years following technological advances that enable non-invasive monitoring of autonomic nervous system regulation. However, the clinical interpretation of HRV features remain widely debated or unknown. Standardisation within studies of HRV in psychiatric disorders is poor, making it difficult to reproduce or build on previous work. Recently, a Guidelines for Reporting Articles on Psychiatry and Heart rate variability checklist has been proposed to address this issue...

BACKGROUND: Childhood trauma has long-term adverse effects on physical and psychological health. Previous studies demonstrated that suicide and mental disorders were related to childhood trauma. In China, there is insufficient research available on childhood trauma in patients with mental disorders. METHODS: Outpatients were recruited from a psychiatric hospital in southern China, and controls were recruited from local communities. The demographic questionnaire, the Childhood Trauma Questionnaire-Short Form (CTQ-SF), and the Social Support Rating Scale (SSRS) were completed by all participants, and the Self-rating Idea of Suicide Scale (SIOSS) were completed only by patients...

Adverse maternal behaviors during pregnancy and unfavorable postnatal experiences during development are associated with an increased risk of developing psychiatric disorders, as well as, a vulnerability to alcohol addiction in adulthood. Here, we examined the effects of combined ethanol exposure during late pregnancy and postnatal maternal separation (MS) on HPA responsiveness, anxiety behavior and preference for alcohol consumption in adult male rats. Animals exposed to both conditions revealed a decrease in blood levels of allopregnanolone accompanied by increased anxiety behavior...

BACKGROUND: The psychiatric ward is a place where all forms of violence are treated. Occasionally, this violence involves acts of aggression between patients in emergency psychiatric units or hospital wards. Such events can lead to the development or worsening of posttraumatic stress disorder. METHODS: To establish the context, we first examined the epidemiology data concerning posttraumatic stress disorder in psychiatric patients who were frequently exposed to assaults...

Fear- and anxiety-related psychiatric disorders have been one of the major chronic diseases afflicting patients for decades, and new compounds for treating such disorders remain to be developed. (+)-Borneol, a bicyclic monoterpene found in several species of Artemisia and Dipterocarpaceae, is widely used for anxiety, pain and anesthesia in Chinese medicine. Meanwhile, it can potentiate GABA (γ-aminobutyric acid) activity directly in recombinant GABAA receptors. The present study was to investigate the effects of (+)-Borneol on both contextual and cued fear recall...

BACKGROUND: Bipolar disorder (BD) is a major psychiatric illness characterized by heterogeneous symptoms including psychotic features. Up until now, neuroimaging studies investigating cerebral morphology in patients with BD have underestimated the potential impact of psychosis on brain anatomy in BD patients. In this regard, psychotic and non-psychotic BD may represent biologically different subtypes of the disorder, being possibly associated with specific cerebral features. METHODS: In the present study, magnetic resonance imaging (MRI) at 3T was used to identify the neuroanatomical correlates of psychosis in an International sample of BD patients...

OBJECTIVE: Medically unexplained physical symptoms (MUPS) are commonly seen across health care settings. Earlier studies have focussed on prevalence, cost-utilization and burden. Data from India is scarce. Patients with persistent MUPS have more impairment and psychological distress. This study was designed to assess psychological morbidity, health anxiety (HA), somatic symptom load, disability, quality of life (QOL) in patients with persistent MUPS presenting to a general medical outpatient service and compare it with patients with medically explained physical symptoms (MEPS)...

High shyness during early adolescence is associated with impaired peer relationships and risk for psychiatric disorders. Little is known, however, about the relation between shyness and trajectories of brain development over early adolescence. The current study longitudinally examined trajectories of resting-state functional connectivity (rs-fc) within four brain networks in 147 adolescents. Subjects underwent functional magnetic resonance imaging at three different time points, at average ages 10.5 (range = 7...

To understand the prenatal origin of developmental and psychiatric disorders, studies in laboratory animals are imperative. However, the developmental pace differs between humans and animals; hence, corresponding human ages must be estimated to infer the most vulnerable developmental timings in humans. Because rats and mice are extensively used as models in developmental research, a correspondence between human foetal ages and rodents' ages must be precisely determined; thus, developing a translational model is of utmost importance...

BACKGROUND: The mechanisms by which parental psychopathology and vulnerability to suicide is transmitted to offspring is not well understood. parental psychopathology and behaviour may impact upon the normal emotional and psychological adjustment of their offspring in various ways. Research shows attachment insecurities may also be a key factor in the facilitation of suicidal behaviours. OBJECTIVE: To examine adult attachment insecurities as a potential mediating pathway between parental psychopathology and 12-month suicidality...

We examined whether the interaction of baseline stimulant use, assessed by urine drug tests, and type of serious mental illness (SMI) diagnosis predicted stimulant use in a trial of contingency management (CM). The interaction between baseline stimulant use and SMI diagnoses was significant in the overall sample (p=0.002) when controlling for the main effects of treatment condition, baseline stimulant use, and SMI diagnosis. Similar results were also found within the CM sample. Individuals with bipolar disorder were more or less likely, depending on their baseline stimulant-drug test results, to use stimulants during treatment compared to those with other SMI diagnoses...

Schizophrenia is a chronic psychiatric disorder generally preceded by a so-called prodromal phase, which is characterized by attenuated psychotic symptoms. Advances in clinical research have enabled prospective identification of those individuals who are at clinical high risk (CHR) for psychosis, with the power to predict psychosis onset within the near future. Changes in several brain neurochemical systems and molecular mechanisms are implicated in the pathophysiology of schizophrenia and the psychosis spectrum, including the dopaminergic, γ-aminobutyric acid (GABA)-ergic, glutamatergic, endocannabinoid, and immunologic (i...

Increased availability of data and accessibility of computational tools in recent years have created an unprecedented upsurge of scientific studies driven by statistical analysis. Limitations inherent to statistics impose constraints on the reliability of conclusions drawn from data, so misuse of statistical methods is a growing concern. Hypothesis and significance testing, and the accompanying P-values are being scrutinized as representing the most widely applied and abused practices. One line of critique is that P-values are inherently unfit to fulfill their ostensible role as measures of credibility for scientific hypotheses...

Repeated exposure to cocaine induces lasting epigenetic changes in neurons that promote the development and persistence of addiction. One epigenetic alteration involves reductions in levels of the histone dimethyltransferase, G9a, in nucleus accumbens (NAc) after chronic cocaine administration. This reduction in G9a may enhance cocaine reward since overexpressing G9a in the NAc decreases cocaine-conditioned place preference. Thus, we hypothesized that HSV-mediated G9a overexpression in the NAc shell (NAcSh) would attenuate cocaine self-administration and cocaine-seeking behavior...
