The activation of cells of the mononuclear phagocyte system, especially microglia and monocytes, has been reported in schizophrenia. We carried out this systematic review and meta-analysis to investigate if there are significant differences in monocyte count comparing healthy controls with people suffering from schizophrenia and related disorders.Methods: We searched main electronic databases; nine records met all our criteria and were included in the meta-analysis. Meta-analyses based on random effects models have been carried out generating pooled standardised mean differences (SMDs) of monocyte count in peripheral blood between schizophrenia and related psychosis and healthy controls. Heterogeneity was estimated. Relevant sensitivity and subgroup analyses were conducted.Results: Patients showed higher monocyte count as compared with healthy control (SMD = 0.393; p = 0.001). Heterogeneity across studies was from moderate to high (I2 = 65.952%); sensitivity analysis leaving out two studies responsible for most of the heterogeneity showed a slightly higher SMD. Subgroup analyses confirmed this result, showing no significant differences in the effect size across different study characteristics.Conclusions: Monocyte count can be considered an indirect marker of microglia activation in the central nervous system. Thus, the observed higher monocyte count in patients could be considered as a possible peripheral marker of microglia's activation in schizophrenia disorder.","PeriodicalId":48964,"journal":{"name":"Acta Neuropsychiatrica","volume":null,"pages":null},"PeriodicalIF":3.8,"publicationDate":"2020-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1017/neu.2020.12","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"37742340","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

International studies provide consistent evidence that the presence of psychiatrists in a region is associated with lesser suicide rates. However, many psychiatric patients including suicidal patients do not have access to psychiatrists. This indicates that mental health and non-mental health social workers need to be involved in suicide prevention efforts. This paper is the first comprehensive work that discusses how to increase the role of social workers in the area of suicide prevention.Methods: A review of the relevant literature.Results: Increasing the role of social workers in suicide prevention efforts may reduce suicide risk in groups and people at elevated risk for suicide, as well as the general population.Conclusion: Recommendations are provided for how the social work profession can improve upon suicide prevention while incorporating universal, selective and indicated suicide preventive interventions. Social work research efforts should focus on how to increase the role of social workers in suicide prevention and the management of suicidal patients. Social work education programmes should modify their curricula and increase their attention on suicide prevention. Mental health social workers need to educate the patient and their family on suicide risk factors. Furthermore, mental health and non-mental health social workers need to educate the general public on suicide risk factors.","PeriodicalId":48964,"journal":{"name":"Acta Neuropsychiatrica","volume":null,"pages":null},"PeriodicalIF":3.8,"publicationDate":"2020-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1017/neu.2020.11","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"37739089","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We performed a standard pairwise meta-analysis using a random effects model and carried out a network meta-analysis (NMA) using the statistical package, R. Quality of evidence was also assessed.Results: We included 67 RCTs in the review and 21 to 45 interventions in the NMA. Paroxetine was most effective in the reduction of symptom severity as compared to placebo. Superior response to treatment was also observed for paroxetine, brofaromine, bromazepam, clonazepam, escitalopram, fluvoxamine, phenelzine, and sertraline. Higher dropout rates were found for fluvoxamine. Brofaromine, escitalopram, fluvoxamine, paroxetine, pregabalin, sertraline, and venlafaxine performed worse in comparison to placebo for the outcome of dropouts due to adverse events. Olanzapine yielded a relatively high rank for treatment efficacy and buspirone the worse rank for dropouts due to any cause.Conclusion: The differences between drugs and placebo were small, apart from a significant reduction in symptom severity and response for paroxetine. We suggest paroxetine as a first-line treatment of SAD, with the consideration of future research on the drug olanzapine as well as brofaromine, bromazepam, clonazepam, escitalopram, fluvoxamine, phenelzine, and sertraline because we observed a response to treatment.","PeriodicalId":48964,"journal":{"name":"Acta Neuropsychiatrica","volume":null,"pages":null},"PeriodicalIF":3.8,"publicationDate":"2020-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1017/neu.2020.6","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"37627536","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Coded sets of randomised ABR recordings intermingled with patients with SZ, adult attention-deficit hyperactivity disorder (ADHD) and healthy controls were analysed by an independent party blinded to clinical diagnoses.Results: The ABR profiling test for SZ was positive in 5/16 patients (31%) and negative in 11/16 patients (69%) with SZA. A surprising finding was that 4/16 (25%) SZA patients were positive for the ABR profiling test for ADHD.Conclusion: With the ABR profiling test, a minority of patients with SZA tested positive for SZ. In contrast, a majority (85%) of patients with SZ in a previous study tested positive. These preliminary results leave us ignorant whether SZA should be regarded as a SZ-like disorder or a psychotic mood disorder and add to the questions regarding the validity of this diagnostic entity.

We therefore chose to investigate how sub-acute depletion or elevation of brain serotonin influences the expression of a number of serotonin-related genes in six brain areas.Methods: Male Wistar rats were administered a serotonin synthesis inhibitor, para-chlorophenylalanine (p-CPA), or a serotonin reuptake inhibitor, paroxetine, for 3 days and then sacrificed. The expression of a number of serotonin-related genes in the raphe nuclei, hypothalamus, amygdala, striatum, hippocampus and prefrontal cortex was investigated using real-time quantitative PCR (rt-qPCR).Results: While most of the studied genes were uninfluenced by paroxetine treatment, we could observe a robust downregulation of tryptophan hydroxylase-2 in the brain region where the serotonergic cell bodies reside, that is, the raphe nuclei. p-CPA induced a significant increase in the expression of Htr1b and Htr2a in amygdala and of Htr2c in the striatum and a marked reduction in the expression of Htr6 in prefrontal cortex; it also enhanced the expression of the brain-derived neurotrophic factor (Bdnf) in raphe and hippocampus.Conclusion: With some notable exceptions, the expression of most of the studied genes is left unchanged by short-term modulation of extracellular levels of serotonin.","PeriodicalId":48964,"journal":{"name":"Acta Neuropsychiatrica","volume":null,"pages":null},"PeriodicalIF":3.8,"publicationDate":"2020-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7282867/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"37648518","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We also investigate potential expectancy bias from the well-known side-effect profile of the active reference that could have affected the study outcome.Methods: Pre-specified sensitivity analyses of the primary end point were performed using analysis of covariance (ANCOVA) last observation carried forward (LOCF) and observed cases (OC). Post hoc analyses of change from baseline in PANSS total score were performed using the mixed model for repeated measures approach with treatment groups split by having typical adverse events with potential for functional unblinding, for example, somnolence, increase in weight, dizziness, dry mouth and sedation.Results: Pre-specified sensitivity analyses showed separation from placebo for brexpiprazole at week 6: LOCF, ANCOVA: -4.3 [95% CI (-8.0, -0.5), p = 0.0254]. OC, ANCOVA: -3.9 [95% CI (-7.3, -0.5), p = 0.0260]. Patients treated with brexpiprazole experiencing typical adverse events with potential for functional unblinding before or at Week 2 had a least square (LS) mean PANSS change of -29.5 (improvement), with a difference in change from baseline to Week 6 in PANSS total score between brexpiprazole and placebo of -13.5 [95% CI (-23.1, -4.0), p = 0.0057], and those who did not had an LS mean change of -18.9 and a difference between brexpiprazole and placebo of -2.9 [95% CI (-7.2, 1.4), p = 0.1809].Conclusion: Pre-specified sensitivity analyses showed separation from placebo for brexpiprazole at Week 6.

We sought to investigate some of these genes in a treatment-free Latino sample of Mexican descent.Material and methods: The sample consisted of 50 MDD treatment-free cases and 50 sex and age-matched controls. Gene expression of candidate genes of neuroplasticity (BDNF, p11, and VGF), inflammation (IL1A, IL1B, IL4, IL6, IL7, IL8, IL10, MIF, and TNFA), the canonical Wnt signaling pathway (TCF7L2, APC, and GSK3B), and mTOR, was compared in cases and controls. RNA was obtained from blood samples. We used bivariate analyses to compare subjects versus control mean mRNA quantification of target genes and lineal regression modelling to test for effects of age and body mass index on gene expression.Results: Most subjects were female (66%) with a mean age of 26.7 (SD 7.9) years. Only GSK3B was differentially expressed between cases and controls at a statistically significant level (p = 0.048). TCF7L-2 showed the highest number of correlations with MDD-related traits, yet these were modest in size.Discussion: GSK3B encodes a moderator of the canonical Wnt signaling pathway. It has a role in neuroplasticity, neuroprotection, depression, and other psychiatric phenotypes. We found that adding population diversity has the potential to elicit distinct peripheral gene expression markers in MDD and MDD-related traits. However, our results should only be considered as hypothesis-generating research that merits further replication in larger cohorts of similar ancestry.","PeriodicalId":48964,"journal":{"name":"Acta Neuropsychiatrica","volume":null,"pages":null},"PeriodicalIF":3.8,"publicationDate":"2020-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"37627537","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
