Unraveling epigenomic signatures and effectiveness of electroconvulsive therapy in treatment-resistant depression patients: a prospective longitudinal study.

Background: Electroconvulsive therapy (ECT) benefits patients with treatment-resistant depression (TRD), but the underlying biological processes are unclear. We conducted an epigenome-wide association study in 32 TRD patients undergoing ECT to depict ECT-associated methylation changes. Illness severity and ECT outcomes were assessed with the Montgomery-Åsberg Depression Rating Scale at baseline (T0) and 1 month after its end (T1).

Childhood neglect, the neglected trauma. A systematic review and meta-analysis of its prevalence in psychiatric disorders.

Traumatic events increase risk of mental illnesses, but childhood neglect prevalence in psychiatric disorders is understudied. This systematic review and meta-analysis assessed neglect prevalence, including emotional neglect (EN) and physical neglect (PN), among adults with psychiatric disorders. We conducted a systematic search and meta-analysis in 122 studies assessing different psychiatric disorders.

Everything changes but nothing changes: gender stereotypes in the Italian population.

Purpose: Gender stereotypes refer to consensual or cultural shared beliefs about the attributes of men and women, influencing society behaviors, interpersonal relationships, education, and workplace. The literature has shown the existence of gender stereotypes on career choices, internalization of roles, and school and social experiences and demonstrates the impact of demographic factors on stereotypes. However, all the studies conducted in Italy available in scientific literature analyzed small sample sizes within specific schools of university settings, with a limited age range.

Biological markers of sex-based differences in major depressive disorder and in antidepressant response.

Major depressive disorder (MDD) presents different clinical features in women and men, with women being more affected and responding differently to antidepressant treatment. Specific molecular mechanisms underlying these differences are not well studied and this narrative review aims at providing an overview of the neurobiological features underlying sex-differences in biological systems involved in MDD pathophysiology and response to antidepressant treatment, focusing on human studies. The majority of the reviewed studies were performed through candidate gene approaches, focusing on biological systems involved in MDD pathophysiology, including the stress response, inflammatory and immune, monoaminergic, neurotrophic, gamma-aminobutyric acid and glutamatergic, and oxytocin systems.

The Elephant in the Room: A Cross-Sectional Study on the Stressful Psychological Effects of the COVID-19 Pandemic in Mental Healthcare Workers.

Despite extensive research on COVID-19's impact on healthcare workers, few studies have targeted mental health workers (MHWs) and none have investigated previous traumatic events. We investigated psychological distress in MHWs after the first lockdown in Italy to understand which COVID-19, sociodemographic, and professional variables represented greater effects, and the role of previous trauma. The survey included sociodemographic and professional questions, COVID-19 variables, and the questionnaires Life Events Checklist for DSM-5 (LEC-5), Impact of Event Scale-Revised (IES-R), and Depression Anxiety Stress Scales 21 (DASS-21).

Inflammation-related microRNAs are involved in stressful life events exposure and in trauma-focused psychotherapy in treatment-resistant depressed patients.

Background: About 30% of major depressive disorder (MDD) patients are classified as resistant to treatment (treatment-resistant depression, TRD). Among the factors associated with unfavourable treatment outcomes, stressful life events play a relevant role, and trauma-focused psychotherapy has been successfully proposed for the treatment of patients with a history of such events. Stressful experiences are related to enhanced inflammation and, recently, microRNAs (miRNAs) have emerged as potential mediators of the association between these experiences and psychiatric disorders.

Molecular Biomarkers of Electroconvulsive Therapy Effects and Clinical Response: Understanding the Present to Shape the Future.

Electroconvulsive therapy (ECT) represents an effective intervention for treatment-resistant depression (TRD). One priority of this research field is the clarification of ECT response mechanisms and the identification of biomarkers predicting its outcomes. We propose an overview of the molecular studies on ECT, concerning its course and outcome prediction, including also animal studies on electroconvulsive seizures (ECS), an experimental analogue of ECT.

Biological correlates of early life stressful events in major depressive disorder.

Major depressive disorder (MDD) is the most common psychiatric disorder and responds for important psychosocial consequences. Stressful life events, especially early life stress (ELS), contribute to an increased probability to develop MDD, leading in particular to severe and chronic manifestation and unfavorable treatment outcome. The association between ELS and MDD seems to have biological bases, consisting in dysregulations occurring at different levels.

Social Cognition in a Research Domain Criteria Perspective: A Bridge Between Schizophrenia and Autism Spectra Disorders.

Schizophrenia and autism spectra disorders are currently conceptualized as distinct clinical categories. However, the relationship between these two nosological entities has been revisited in recent years due to the evidence that they share some important clinical and neurobiological features, putting into question the nature and the extent of their commonalities and differences. In this respect, some core symptoms that are present in both disorders, such as social cognitive deficits, could be a primary target of investigation.

Genomic changes in progression of low-grade gliomas.

Using a one-megabase BAC-based array comparative genomic hybridization technique (aCGH), we have investigated a series of 16 low-grade gliomas (LGGs) and their subsequent progression to higher-grade malignancies. The most frequent chromosome imbalances in primary tumors were gains of chromosomes 7q, 8q, and 22q, and losses of chromosomes 1p, 13q, and 19q. In tumor progression, gains of chromosomes 11q, 7q, 20q, and 21q, and losses of chromosomes 9p, including CDKN2A locus, 19q, 14q, 1p, and 6q were the most frequent genomic disequilibria.

Clobazam as add-on therapy in children with epileptic encephalopathy.

Rationale: Clobazam has been used successfully in adults and children with partial epilepsy. The purpose of this study was to evaluate the safety and efficacy of clobazam as add-on therapy in children with epileptic encephalopathy.

Methods: This was a retrospective study conducted at the pediatric epilepsy clinic of our university hospital.
