The default mode network (DMN) is atypically active in patients with ADHD, likely contributing to the inattention patterns observed in patients with the disorder. Nonetheless, magnetic resonance spectroscopy (MRS) studies have rarely targeted the posterior cingulate cortex, a key DMN region, and little is known about the biochemical setting within this network in patients with ADHD. We aimed to assess the differences in metabolite profiles of the posterior cingulate cortex-a key region of the DMN-between patients with ADHD and controls.

Importance: Transcranial direct current stimulation (tDCS) may improve symptoms of inattention in adults with attention-deficit/hyperactivity disorder (ADHD). However, previous trials are characterized by small sample sizes, heterogeneous methodologies, and short treatment periods using clinic-based tDCS.
Objective: To determine the efficacy and safety of home-based tDCS in treating inattention symptoms in adult patients with ADHD.
The Forkhead box P2 (FOXP2) encodes for a transcription factor with a broad role in embryonic development. It is especially represented among GWAS hits for neurodevelopmental disorders and related traits, including attention-deficit/hyperactivity disorder (ADHD), autism spectrum disorder, neuroticism, and risk-taking behaviors. While several functional studies are underway to understand the consequences of FOXP2 variation, this study aims to expand previous findings to clinically and genetically related phenotypes and neuroanatomical features among subjects with ADHD.

This study aimed to examine the associations between countertransference induced by sex offenders, defense mechanisms, and manifestations of vicarious trauma in forensic psychiatrists and psychologists. A cross-sectional study using a mixed-methods design was performed with 56 Brazilian forensic psychiatrists and psychologists from October 2016 to May 2017. Countertransference, defense mechanisms, and vicarious trauma were assessed with the Assessment of Countertransference Scale, the Defense Style Questionnaire-40, and the Trauma and Attachment Belief Scale (TABS), respectively.

Methods: The 113 sessions were videotaped and analyzed alternately (n = 60) by independent judges using the Psychotherapy Process Q-Set. Inter-rater reliability ranged from 0.
Background: As more patients are surviving intensive care, mental health concerns in survivors have become a research priority. Among these, post-traumatic stress disorder (PTSD) can have an important impact on the quality of life of critical care survivors. However, data on its burden are conflicting.

However, there are no established guidelines on the most appropriate time to perform these measurements.
Objectives: The aim of this study is to problematize what is the appropriate time to measure the initial outcomes (symptoms, interpersonal relationships, quality, and social role) and process factors (alliance) in the early stages of PDT.
Objective: This article concerns the translation, cross-cultural adaptation, and apparent validation of the Trauma and Attachment Belief Scale (TABS), an instrument used to assess the psychological effects of traumatic life experiences and vicarious trauma.
Methods: This study involved literature review and evaluation of conceptual and item equivalences involving expert discussion groups focused on the existence and pertinence of the underlying theoretical concepts and corresponding items in a Brazilian context. Two translations and respective back-translations were performed during the evaluation of semantic equivalence, as well as an evaluation considering the referential and general equivalences between the original TABS and each version.
Attention-deficit/hyperactivity disorder (ADHD) is a very common psychiatric disorder across the life cycle and frequently presents comorbidities. Since ADHD is highly heritable, several studies have focused in the underlying genetic factors involved in its etiology. One of the major challenges in this search is the phenotypic heterogeneity, which could be partly attributable to the sexual dimorphism frequently seen in psychiatric disorders.

The exposition to traumatic events related to urban violence is epidemic in Brazil, with rate of 80% in the general population, and is becoming a major cause of post-traumatic stress disorder (PTSD). The objective of the study was to compare serum levels of pro-inflammatory interleukin-6 (IL-6) and anti-inflammatory interleukin-10 (IL-10) in PTSD and resilient individuals. We hypothesized that resilient individuals present an attenuated pro-inflammatory and enhanced anti-inflammatory state.

A secondary objective is to assess associations between CT and variables related to therapist and patient and between CT and other patient variables investigated, which were defense mechanisms, symptomology and functionality.
Methodology: This was a cross-sectional study that enrolled 30 patients treated by 17 different therapists at the psychotherapy clinics of two psychiatry centers.
Objective: To investigate whether internalizing disorders are associated with quality of life (QoL) in adolescents, even after accounting for shared risk factors.
Methods: The sample comprised 102 adolescents from a community cross-sectional study with an oversampling of anxious subjects. Risk factors previously associated with QoL were assessed and divided into five blocks organized hierarchically from proximal to distal sets of risk factors.

In this age of unprecedented expansion of media and information dissemination and sharing, the use of electronic means should be reconsidered. The use of new technologies should be studied to understand how it may affect the relationship between patient and therapist during psychotherapy or psychoanalytic treatments. This study offers a critical discussion of the effect of technologies on clinical practice, and vignettes are used to describe their impact on frame, anonymity, abstinence and therapeutic neutrality.

In reviewing the classic literature on the topic, aspects such as age, diagnosis, motivation for treatment, present moment in life, ability to gain insight, psychic suffering when seeking treatment, defensive behaviors, and frustration tolerance are clearly analyzed by therapists/analysts when indicating psychoanalytic treatments. However, traditionally, most criteria underlying such indications date back to a time when the therapeutic relationship was viewed merely as a therapist treating a patient, with no regard to the therapeutic relationship itself.
