Dopaminergic Epistases in Schizophrenia.

The dopaminergic theory, the oldest and most comprehensively analyzed neurotransmitter theory of schizophrenia, remains a focal point of research. This systematic review examines the association between combinations of 14 dopaminergic genes and the risk of schizophrenia. The selected genes include dopamine receptors (DRD1-5), metabolizing enzymes (COMT, MAOA, MAOB, DBH), synthesizing enzymes (TH, DDC), and dopamine transporters (DAT, VMAT1, and VMAT2).

Cognitive Impairments Related to COMT and Neuregulin 1 Phenotypes as Transdiagnostic Markers in Schizophrenia Spectrum Patients.

Research on the interaction between antipsychotic treatment and cognitive dysfunction in schizophrenia spectrum disorders (SSDs) is extensive, yet the role of genetic polymorphisms in catechol-O-methyltransferase (COMT) and neuregulin 1 (NRG1) remains underexplored. : This study evaluates the impact of COMT (rs4680) and NRG1 (rs3924999 and rs35753505) polymorphisms on cognitive functions in SSD patients. A cross-sectional study was conducted with fifty-four patients, assessed using the Positive and Negative Syndrome Scale (PANSS) and the CNS Vital Signs battery.

Health Impacts of Pre-eclampsia: A Comprehensive Analysis of Maternal and Neonatal Outcomes.

: Hypertensive disorders, particularly pre-eclampsia, pose significant risks during pregnancy, affecting both maternal and neonatal health. The study aims to analyze short- and long-term health implications for mothers and their children, comparing those with pre-eclampsia to those without, to improve understanding of risk factors, diagnostic markers, and outcomes. : This retrospective observational study involved 235 patients, 98 with pre-eclampsia and 137 without, monitored from 2015 to 2018 at the Obstetrics and Gynecology Department of the "Pius Brînzeu" Emergency County Clinical Hospital in Timișoara, Romania.

Coffee Consumption and Polymorphism Involvement in Type 2 Diabetes in a Romanian Population.

Unlabelled: Cytochrome P450 1A2 (CYP1A2) is known to be the main enzyme directly responsible for caffeine metabolism. Rs762551 (NC_000015.10:g.

COMT and Neuregulin 1 Markers for Personalized Treatment of Schizophrenia Spectrum Disorders Treated with Risperidone Monotherapy.

Pharmacogenetic markers are current targets for the personalized treatment of psychosis. Limited data exist on COMT and NRG1 polymorphisms in relation to risperidone treatment. This study focuses on the impact of COMT rs4680 and NRG1 (rs35753505, rs3924999) polymorphisms on risperidone treatment in schizophrenia spectrum disorders (SSDs).
