A call for greater diversity and representativity within countries in psychiatric research: Lessons and challenges from a systematic review of schizophrenia research in Brazil.

Objective: This article aims to systematically review the studies on schizophrenia in Brazil, addressing geographical coverage as an indicator of sampling representativeness, essential to infer results' generalization. It also highlights the variation in research funding across different regions.

Methods: We searched for studies carried out until July 2023.

Longitudinal Patterns of Disordered Eating Behaviors in Children and Adolescents from the Brazilian High-Risk Cohort Study for Mental Conditions.

Objective: Disordered Eating Behaviors (DEB) are associated with dysfunctional changes in eating behavior, not meeting diagnostic criteria for eating disorders. DEB affects a significant percentage of individuals, yet it remains under-researched. The current study investigates the developmental trajectory and psychopathological correlates of DEB in children and adolescents in Brazil.

Hematological Changes in Clozapine Users: A Study in a Brazilian Community Sample.

Introduction: Clozapine is the only antipsychotic with proven superior efficacy for treatment-resistant schizophrenia. However, global utilization rates remain suboptimal due to concerns about hematological side effects. This study aimed to investigate hematological abnormalities among clozapine users at a large community center in the Brazilian countryside.

Collaborative Outcomes Study on Health and Functioning During Infection Times (COH-FIT): Global and Risk-Group Stratified Course of Well-Being and Mental Health During the COVID-19 Pandemic in Adolescents.

Objective: To identify the COVID-19 pandemic impact on well-being/mental health, coping strategies, and risk factors in adolescents worldwide.

Method: This study was based on an anonymous online multi-national/multi-language survey in the general population (representative/weighted non-representative samples, 14-17 years of age), measuring change in well-being (World Health Organization-Five Well-Being Index [WHO-5]/range = 0-100) and psychopathology (validated composite P-score/range = 0-100), WHO-5 <50 and <29, pre- vs during COVID-19 pandemic (April 26, 2020-June 26, 2022). Coping strategies and 9 a priori- defined individual/cumulative risk factors were measured.

Spotted fever diagnosis using molecular methods.

Rickettsiosis is a disease caused by bacteria belonging to the genus Rickettsia, and is a potentially fatal zoonotic disease of great medical and veterinary importance. Given the urgent need to develop new diagnostic methods for detecting this disease, the present review aimed to evaluate the number of publications dedicated to the identification of Rickettsia spp. in human samples using molecular methods, such as polymerase chain reaction and its variations.
