Association of rs4680 COMT, rs6280 DRD3, and rs7322347 5HT2A With Clinical Features of Youth-Onset Schizophrenia

We investigated the associations of rs4680 COMT, rs6280 DRD3, and rs7322347 5HT2A with youth-onset schizophrenia in the Russian population in a case–control study, and the role of the genotype in the severity of clinical features. The association between rs7322347 and schizophrenia (p = 0.0001) is described for the first time. Furthermore, we found a link with rs6280 and rs4680 in females (p = 0.001 and p = 0.02 respectively) and with rs7322347 in males (p = 0.002). Clinical symptoms were assessed on three scales: the Clinician-Rated Dimensions of Psychosis Symptom Severity scale, Positive and Negative Syndrome Scale, and Frontal Assessment Battery. Gender differences in clinical features are of particular interest. In our study we found gender differences in the severity of clinical features—higher scores for delusions (Positive and Negative Syndrome Scale and Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition) in males and higher scores for depression, delusions, somatic concern, motor retardation, poor attention were found in females.

Publication date: Available online 7 December 2019Source: Saudi Pharmaceutical JournalAuthor(s): Kinga OstrowskaAbstractA number of psychiatric disorders, including anxiety, schizophrenia, Parkinson’s disease, depression and others CNS diseases are known to induce defects in the function of neural pathways sustained by the neurotransmitters, like dopamine and serotonin. N-arylpiperazine moiety is important for CNS-activity, particularly for serotonergic and dopaminergic activity. In the scientific literature there are many examples of coumarin-piperazine derivatives, particularly with arylpiperazines linked to a coum...

Functional coupling of M1 muscarinic acetylcholine receptor to Gαq/11 in dorsolateral prefrontal cortex from patients with psychiatric disorders: a postmortem study. Eur Arch Psychiatry Clin Neurosci. 2019 Dec 05;: Authors: Odagaki Y, Kinoshita M, Meana JJ, Callado LF, García-Sevilla JA Abstract Accumulating studies have implicated intracellular signaling through muscarinic acetylcholine receptors (mAChRs) in psychiatric illness. In the present study, carbamylcholine chloride (carbachol)-induced Gαi/o and Gαq/11 activation was identified in postmortem human prefrontal cortical ...

ConclusionsRumination is known to be associated with poor prognosis in mental health. This study suggests that rumination is a maladaptive coping style associated not only with worry, distress and illness severity, but also with socioeconomic status. Also, rumination demonstrated a specific association with panic disorder.

BriedéAbstractCirculating microRNAs (cimiRNAs) are a class of non-encoding RNAs found in bodily fluids such as blood, cerebrospinal fluid (CSF) and tears. CimiRNAs have been implicated as promising biomarkers for central nervous system (CNS) disorders because they are actively secreted as messengers and are profoundly involved in fine-tuning of developmental and differentiation processes. Furthermore, they are attractive biomarkers becau...

AbstractMajor psychiatric traits are genetically inter-correlated with one another, but it not well known which genes play pleiotropic effects across different traits. We curated and compared genes identified from large-scale genome-wide association studies for seven psychiatric traits, including depression, bipolar disorder, schizophrenia, autism spectrum disorder, attention-deficit/hyperactivity disorder, anxiety and neuroticism. We then explored biological functions of the top pleiotropic genes. A total of 243 cross-trait genes were identified for the seven traits. Except for autism spectrum disorder, there was signific...

Almost half (48%) of children and adolescents with a psychotic disorder said they recently had suicidal thoughts or had in the past considered death by suicide when interviewed in the emergency department (ED) using a brief screening questionnaire, according to areport published this week inPsychiatric Services. Most of these youth did not report a chief complaint related to suicidal ideation or behavior when arriving at the ED.Notably, half of the children and adolescents who screened positive for suicide using the Ask Suicide-Screening Questions (ASQ) screen were discharged from the ED, including 44% of those who reporte...

Authors: Pershad Y, Guo M, Altman RB Abstract One in five Americans experience mental illness, and roughly 75% of psychiatric prescriptions do not successfully treat the patient's condition. Extensive evidence implicates genetic factors and signaling disruption in the pathophysiology of these diseases. Changes in transcription often underlie this molecular pathway dysregulation; individual patient transcriptional data can improve the efficacy of diagnosis and treatment. Recent large-scale genomic studies have uncovered shared genetic modules across multiple psychiatric disorders - providing an opportunity for an in...

In this study, 54 children aged 6–9 years (0.58%, CI 0.47–0.77), 64 adolescents aged 10–14 years (0.57%, CI 0.47–0.77), and 117 adolescents aged 15–18 years (1.22%, CI 0.96–1.44) met the criteria of the lifetime conduct disorder. Conduct disorder was significantly more common in boys than in girls, and was significantly less prevalent among those participants whose fathers had no history of psychiatric hospitalization. Of the participants with conduct disorder, 83.4% met the criteria for at least one other psychiatric disorder. Conduct disorder had a high rate of comorbidity with opposit...
