A narrative review of nosology and the concept of schizophrenia: criticism and proposal.

Schizophrenia diagnostics have evolved to adapt to clinical needs and scientific advances, and the current denominations emerged at the beginning of the twentieth century. Most problems arise while integrating clinical experiences, based on historical psychopathological descriptions, with emerging translational neuroscience research. This study aimed to evaluate the state-of-the-art critics of the current schizophrenia concept and their recommendations for new concepts.

Screening for posttraumatic stress disorder (PTSD) in Mozambique: Validation of the Primary Care Posttraumatic Stress Disorder Screen for Diagnostic and Statistical Manual fifth edition (PC-PTSD-5).

Objective: The confluence of conflict-, climate-, and public health-related emergencies in Mozambique increases the risk of posttraumatic stress disorder (PTSD). Few brief screening tools for PTSD have been validated in low- and middle-income countries. We aimed to validate the five-item Primary Care PTSD Screen for the (5th ed.

Leveraging Social Networks to Integrate Depression Treatment into Primary Health and Tuberculosis Care in Brazil.

Background: Tuberculosis (TB) and depression are highly comorbid and linked to higher rates of death and disability. Several evidence-based treatments for depression have been successfully implemented in low- and middle-income countries, but more knowledge is needed on how to bring these innovations to scale within complex 'real world' public health systems.

Objective: To explore whether the principles of social network analysis could be used to enhance receptivity to integrating depression treatment into primary care for individuals with and without TB in Brazil.

The S20 Brazilian Mental Health Report for building a just world and a sustainable planet: Part I.

This is the first part of two documents prepared by experts for the Brazilian S20 mental health report. These reports outline strategies aimed at addressing the exacerbated mental health challenges arising from a post-pandemic world. Ongoing psychiatric epidemiology research has yielded evidence linking mental health with intricate social determinants, including gender, race/ethnicity, racism, socioeconomic status, social deprivation, and employment, among others.

The interaction between polygenic risk score and trauma affects the likelihood of post-traumatic stress disorder in female victims of sexual assault.

Objective: Post-traumatic stress disorder (PTSD) is triggered by traumatic events, but genetic vulnerability and a history of childhood trauma may also increase the risk of PTSD onset. Thus, we investigated the interaction between genetic susceptibility according to polygenic risk score (PRS), and traumatic events.

Methods: We evaluated 68 women with PTSD who had been sexually assaulted and 63 healthy controls with no history of sexual assault.

Moral injury and mental health among health-care workers during the COVID-19 pandemic: meta-analysis.

: During the COVID-19 pandemic, health-care workers (HCWs) may have been confronted with situations that may culminate in moral injury (MI). MI is the psychological distress that may result from perpetrating or witnessing actions that violate one's moral codes. Literature suggests that MI can be associated with mental health problems.

Changes in attachment dimensions during the treatment of acute post-traumatic stress disorder in sexually assaulted Brazilian women.

Introduction: Attachment patterns are established during early childhood; however, extreme experiences throughout life may change this structure, either toward attachment security or insecurity. We analyzed changes in attachment dimensions in women with acute post-traumatic stress disorder (PTSD) following sexual assault, that were randomized to a 14-week treatment with either the medication sertraline or Interpersonal Psychotherapy.

Methods: Seventy-four adult women who presented significant reduction in PTSD symptoms across the trial responded to the Revised Adult Attachment Scale at baseline, on week 8 of treatment, and at the end of the trial, on week 14.

The relationship between tonic immobility and the development, severity, and course of posttraumatic stress disorder: Systematic and meta-analytic literature review.

Background: Tonic immobility (TI) is a reflexive, involuntary response that causes motor inhibition, vocal suppression, and analgesia. TI is elicited by extreme fear and perception of entrapment in a life-threatening situation. Research suggests that TI is a frequent peritraumatic response and may be related to subsequent posttraumatic stress disorder (PTSD).

Association between mental disorders and adherence to antiretroviral treatment in health facilities in two Mozambican provinces in 2018: a cross-sectional study.

Introduction: Lower adherence to antiretroviral treatment (ART) has been found among people with HIV (PWH) who have comorbid mental disorders like depression and alcohol use in Sub-Saharan African. However, there has been less exploration with regards to other mental disorders.

Methods: This study assessed the association of multiple mental disorders and adherence to ART based on the data from primary/tertiary health care facilities in Maputo and Nampula, Mozambique.

Sleep characteristics and inflammatory markers in women with post-traumatic stress disorder.

Introduction: Sexual violence is one of the most severe traumatic events. It is associated with a higher risk for post-traumatic stress disorder (PTSD) development. Sleep disturbances such as insomnia are frequently reported by PTSD patients and play a key role in the development and course of the disorder.

Hyperarousal Symptom Severity in Women with Posttraumatic Stress Disorder Might Be Associated with LINE-1 Hypomethylation in Childhood Sexual Abuse Victims.

Introduction: Sexual assault and a history of childhood sexual abuse (CSA) are related to posttraumatic stress disorder (PTSD) development. Long interspersed nuclear elements (LINE-1) are transposable elements, and their methylation is used to infer DNA global methylation. DNA methylation can be affected by trauma exposition which in turn would be associated with PTSD.

Interpersonal psychotherapy versus sertraline for women with posttraumatic stress disorder following recent sexual assault: a randomized clinical trial.

Sexual assault often triggers posttraumatic stress disorder (PTSD), a potentially chronic severe mental disorder. Most guidelines recommend selective serotonin reuptake inhibitors (SSRIs) and trauma-focused psychotherapies as treatment options. Interpersonal Psychotherapy (IPT), adapted for PTSD (IPT-PTSD), focuses on interpersonal consequences of trauma rather than confronting the trauma itself.

Lay HIV counselors' knowledge and attitudes toward depression: A mixed-methods cross-sectional study at primary healthcare centers in Mozambique.

Introduction: Depression is the most common mental disorder among people living with HIV/AIDS and has a negative impact on HIV treatment outcomes. Training lay HIV counselors to identify and manage depression may contribute to improved patient access and adherence to treatment, and reduce stigma and discrimination among lay health workers toward both HIV and depression. The purpose of this study was to assess the current knowledge and attitudes of lay HIV counselors toward managing depression in primary care in Mozambique.

Increased immuno-inflammatory mediators in women with post-traumatic stress disorder after sexual assault: 1-Year follow-up.

Background: Sexual violence is a traumatic event that can trigger post-traumatic stress disorder (PTSD) and generate biological responses to stress characterized by inhibiting the hypothalamic-pituitary axis (HPA), altering immune activity, and changing the structure and function of the brain. PTSD is associated with increased levels of inflammatory markers. This study aimed to measure differences in inflammatory markers and HPA hormone levels between women with PTSD due to sexual violence and controls at baseline and after 1-year follow-up.

Peri-Traumatic Dissociation and Tonic Immobility as Severity Predictors of Posttraumatic Stress Disorder After Rape.

Some individuals show abnormal reactions to extreme fear and life-threatening situations, including tonic immobility (TI) and peri-traumatic dissociation (PTD). We aimed to investigate the association of TI and PTD with posttraumatic stress disorder (PTSD) in women who experienced sexual violence and the risk factors for PTD occurrence. We compared PTSD severity in 86 young adult women with PTSD after a sexual violence exposure grouped according to the presence of PTD and TI.

The positive impact of maternal depression intervention on children's emotional and behavioral symptoms in a low-resource setting.

Objective: Children of depressed mothers are at risk of developing mental health problems. We sought to determine whether treatment for maternal depression delivered by community health workers (CHW) would decrease behavioral/emotional symptoms in their child. An intervention treating maternal depressive symptoms in a low-middle-income country can have a high global impact.

Shorter Telomeres Related to Posttraumatic Stress Disorder Re-experiencing Symptoms in Sexually Assaulted Civilian Women.

Telomeres are short tandem repeats of "TTAGGG" that protect the chromosome ends from deterioration or fusion of chromosomes. Their repeat length shortens with cell division acting as a biomarker of cellular aging. Traumatic stress events during adulthood or childhood have been associated with posttraumatic stress disorder (PTSD) and short leukocyte telomere length (LTL).

Association of Task-Shared Psychological Interventions With Depression Outcomes in Low- and Middle-Income Countries: A Systematic Review and Individual Patient Data Meta-analysis.

Importance: Task sharing, the training of nonspecialist workers with no formal experience in counseling, is a promising strategy for addressing the large gap in treatment for depression in low- and middle-income countries (LMICs).

Objective: To examine the outcomes and moderators of task-shared psychological interventions associated with depression severity, response, and remission.

Data Sources: Systematic literature searches in PubMed, Embase, PsycINFO, and Cochrane Library up to January 1, 2021.

Identifying posttraumatic stress disorder staging from clinical and sociodemographic features: a proof-of-concept study using a machine learning approach.

This proof-of-concept study aimed to investigate the viability of a predictive model to support posttraumatic stress disorder (PTSD) staging. We performed a naturalistic, cross-sectional study at two Brazilian centers: the Psychological Trauma Research and Treatment (NET-Trauma) Program at Universidade Federal of Rio Grande do Sul, and the Program for Research and Care on Violence and PTSD (PROVE), at Universidade Federal of São Paulo. Five supervised machine-learning algorithms were tested: Elastic Net, Gradient Boosting Machine, Random Forest, Support Vector Machine, and C5.

The relationship between recent PTSD secondary to sexual assault, hippocampal volume and resting state functional connectivity in adolescent girls.

Objective: Improved understanding of the time course of neural changes associated with adolescent PTSD would elucidate the development of the disorder and could inform approaches to treatment. We compared hippocampal volumes and resting state functional connectivity (RSFC) in adolescent girls with post-traumatic stress disorder (PTSD) secondary to sexual assault, within six months of onset and age- and gender-matched, non-trauma exposed healthy controls (HCs) in São Paulo, Brazil. We also examined the relationship between pre- and post-treatment PTSD symptoms and RSFC.

The impact of neighborhood context on telomere length: A systematic review.

A growing body of research demonstrates the association between neighborhood context and health. The underlying biological mechanisms of this association are not fully understood. We conducted a systematic review of studies that investigated the association between neighborhood context and telomere length (TL), a DNA-protein complex that shortens after cell division.
