ABSTRACT

Objectives: To compare hair cortisol concentrations (HCC) in drug-naïve first-episode psychosis (FEP) patients and healthy controls and to investigate the correlations between HCC and psychopathology. Methods: Twenty-four drug-naïve FEP patients and 27 gender- and age-matched healthy control subjects were recruited. The Structured Clinical Interview for DSM-IV (SCID-1) was used to confirm/rule out diagnoses, and the Positive and Negative Symptoms Scale (PANSS) was used to assess symptom severity. Hair samples (2-3 cm long) obtained from the posterior vertex region of the scalp were processed in 1-cm segments considering a hair growth rate of 1 cm per month. The 1-cm segments were classified according to their proximity to the scalp: segment A was the closest to the scalp and referred to the month prior to inclusion in the study. Segments B and C referred to the 2nd and 3rd months prior to the time of evaluation respectively. Hair steroid extraction was performed using a known protocol. Results: Two-way analysis of covariance (ANCOVA) with gender and age as covariates revealed a group effect (F1.106 = 4.899, p = 0.029) on HCC. Between-segment differences correlated with total PANSS score and with PANSS General Psychopathology subscale and total score. Conclusions: Our findings suggest that hypothalamic-pituitary-adrenal (HPA) axis, as assessed by long-term (3-month) cortisol concentration, is abnormal in the early stages of psychosis. The magnitude of changes in HCC over time prior to the FEP correlates to psychopathology. HPA axis abnormalities might begin prior to full-blown clinical presentation requiring hospital admission.

ABSTRACT

Objective: To characterize the early stages of bipolar disorder (BD), defined as the clinical prodrome/subsyndromal stage and first-episode phase, and strategies for their respective treatment. Methods: A selective literature search of the PubMed, Embase, PsycINFO, and ISI databases from inception until March 2014 was performed. Included in this review were articles that a) characterized prodromal and first-episode stages of BD or b) detailed efficacy and safety/tolerability of interventions in patients considered prodromal for BD or those with only one episode of mania/hypomania. Results: As research has only recently focused on characterization of the early phase of BD, there is little evidence for the effectiveness of any treatment option in the early phase of BD. Case management; individual, group, and family therapy; supportive therapy; and group psychoeducation programs have been proposed. Most evidence-based treatment guidelines for BD do not address treatment specifically in the context of the early stages of illness. Evidence for pharmacotherapy is usually presented in relation to illness polarity (i.e., manic/mixed or depressed) or treatment phase. Conclusions: Although early recognition and treatment are critical to preventing unfavorable outcomes, there is currently little evidence for interventions in these stages of BD.

ABSTRACT

BACKGROUND: Bipolar disorder (BD) is a chronic and often severe mental disease, associated with a significant burden in affected individuals. The characterization of a premorbid (prodromal) period and possible development of preventive interventions are recent advances in this field. Attempts to characterize high-risk stages in BD, identifying symptoms prior to the emergence of a first manic/hypomanic episode, have been limited by a lack of standardized criteria and instruments for assessment. The Bipolar Prodrome Symptom Scale-Retrospective (BPSS-R), developed by Correll and collaborators, retrospectively evaluates symptoms that occur prior to a first full mood episode in individuals with BD. OBJECTIVE: To describe the translation and adaptation process of the BPSS-R to Brazilian Portuguese. METHOD: Translation was conducted as follows: 1) translation of the scale from English to Brazilian Portuguese by authors who have Portuguese as their first language; 2) merging of the two versions by a committee of specialists; 3) back-translation to English by a translator who is an English native speaker; 4) correction of the new version in English by the author of the original scale; 5) finalization of the new version in Brazilian Portuguese. RESULTS: All the steps of the translation process were successfully accomplished, resulting in a final version of the instrument. CONCLUSIONS: The Brazilian Portuguese version of the BPSS-R is a potentially useful instrument to investigate prodromal period of BD in Brazil


INTRODUÇÃO: O transtorno bipolar (TB) é um transtorno mental crônico e muitas vezes grave, associado a um significativo prejuízo psicossocial nos indivíduos afetados. A caracterização de um período pré-mórbido (prodrômico) e o possível desenvolvimento de intervenções preventivas são avanços recentes na área. Tentativas de caracterizar estágios de alto risco para o TB, através da identificação de sintomas antes do aparecimento de um primeiro episódio maníaco/hipomaníaco, têm sido limitadas pela falta de critérios padronizados e instrumentos de avaliação. A Bipolar Prodrome Symptom Scale-Retrospective (BPSS-R), desenvolvida por Correll e colaboradores, avalia retrospectivamente os sintomas que ocorrem antes de um episódio sindrômico de humor em indivíduos com TB. OBJETIVO: Descrever o processo de tradução e adaptação da BPSS-R para português brasileiro. MÉTODO: A tradução foi conduzida como segue: 1) tradução da escala de inglês para português brasileiro por autores que têm o português como língua materna; 2) junção das duas versões por um comitê de especialistas; 3) retrotradução para inglês por um tradutor que tem inglês como língua materna; 4) correção da nova versão em inglês pelo autor do instrumento original; 5) finalização da nova versão em português brasileiro. RESULTADOS: Todos os passos do processo de tradução foram completados com sucesso, resultando em uma versão final do instrumento. CONCLUSÕES: A versão da BPSS-R em português brasileiro é um instrumento potencialmente útil para investigar o período prodrômico do TB no Brasil

ABSTRACT

OBJECTIVE: Advances in our knowledge of mental disorder (MD) genetics have contributed to a better understanding of their pathophysiology. Nonetheless, several questions and doubts persist. Recent studies have focused on environmental influences in the development of MDs, and the advent of neuroscientific methodologies has provided new perspectives. Early life events, such as childhood stress, may affect neurodevelopment through mechanisms such as gene-environment interactions and epigenetic regulation, thus leading to diseases in adulthood. The aim of this paper is to review the evidence regarding the role of the environment, particularly childhood stress, in the pathophysiology of MD. METHODOLOGY: We reviewed articles that evaluated environmental influences, with a particular focus on childhood trauma, brain morphology, cognitive functions, and the development of psychopathology and MD. RESULTS AND CONCLUSION: MRI studies have shown that exposure to trauma at an early age can result in several neurostructural changes, such as the reduction of the hippocampus and corpus callosum. Cognitive performance and functioning are also altered in this population. Finally, childhood stress is related to an increased risk of developing MD such as depression, bipolar disorder, schizophrenia and substance abuse. We conclude that there is robust evidence of the role of the environment, specifically adverse childhood experiences, in various aspects of MD.


OBJETIVO: Avanços no conhecimento da genética dos transtornos mentais (TM) contribuíram para um melhor entendimento de suas bases fisiopatológicas. No entanto, dúvidas e questões ainda persistem. Estudos recentes têm se concentrado nas influências do ambiente no desenvolvimento de TM, e o advento de metodologias neurocientíficas oferece novas perspectivas. Eventos precoces de vida, como estresse na infância, podem ser capazes de alterar o neurodesenvolvimento através de mecanismos como interação gene-ambiente e regulação epigenética, resultando em patologias na idade adulta. O objetivo deste artigo é revisar as evidências referentes ao papel do ambiente, em especial o estresse na infância, na fisiopatologia de TM. METODOLOGIA: Revisamos artigos que avaliam as influências ambientais, com um foco especial no trauma na infância, na morfologia cerebral, nas funções cognitivas e no desenvolvimento de psicopatologias e TM. RESULTADOS E CONCLUSÃO: Estudos com ressonância magnética demonstram que a exposição a traumas em uma idade precoce pode levar a diversas alterações neuroestruturais, como a diminuição do hipocampo e do corpo caloso. O desempenho e o funcionamento cognitivo também são alterados nessa população. Por fim, o estresse na infância está ligado a um maior risco de desenvolver TM como depressão, transtorno bipolar, esquizofrenia e abuso de substâncias. Concluímos que existem evidências sólidas quanto à importância do ambiente, especificamente das experiências adversas na infância, em diversos aspectos dos TM.

ABSTRACT

Metabolic abnormalities are frequent in patients with schizophrenia and bipolar disorder (BD), leading to a high prevalence of diabetes and metabolic syndrome in this population. Moreover, mortality rates among patients are higher than in the general population, especially due to cardiovascular diseases. Several neurobiological systems involved in energy metabolism have been shown to be altered in both illnesses; however, the cause of metabolic abnormalities and how they relate to schizophrenia and BD pathophysiology are still largely unknown. The "selfish brain" theory is a recent paradigm postulating that, in order to maintain its own energy supply stable, the brain modulates energy metabolism in the periphery by regulation of both allocation and intake of nutrients. We hypothesize that the metabolic alterations observed in these disorders are a result of an inefficient regulation of the brain energy supply and its compensatory mechanisms. The selfish brain theory can also expand our understanding of stress adaptation and neuroprogression in schizophrenia and BD, and, overall, can have important clinical implications for both illnesses (AU)


Alterações metabólicas são frequentes em pacientes com esquizofrenia e transtorno bipolar (TB), levando a uma alta prevalência de diabetes e síndrome metabólica nessa população. Além disso, as taxas de mortalidade entre pacientes são mais altas do que na população geral, especialmente em decorrência de doenças cardiovasculares. Vários sistemas neurobiológicos envolvidos no metabolismo energético têm demonstrado alterações nas duas doenças; no entanto, a causa das alterações metabólicas e a forma como elas se relacionam com a fisiopatologia da esquizofrenia e do TB ainda são arenas em grande parte desconhecidas. A teoria do "cérebro egoísta" é um paradigma recente que postula que, para manter estável seu próprio fornecimento de energia, o cérebro modula o metabolismo da energia na periferia regulando tanto a alocação quanto a ingestão de nutrientes. Apresentamos neste artigo a hipótese de que as alterações metabólicas observadas nesses transtornos são resultado de uma regulação ineficiente do fornecimento de energia do cérebro e seus mecanismos compensatórios. A teoria do cérebro egoísta também pode expandir nosso entendimento sobre a adaptação ao estresse e a neuroprogressão na esquizofrenia e no TB, e, acima de tudo, pode ter implicações clínicas importantes para as duas doenças (AU)

ABSTRACT

OBJECTIVE: This article aims to review Latin America's early intervention services in psychosis and to shed light into their challenges and particularities. METHOD: An internet-based search comprising medical societies' websites, published articles, and major universities' websites was conducted and the results were critically discussed. RESULTS: Latin American countries are profoundly deficient in specialized early intervention services. Our search found seven target services, four of which are based in urban areas of Brazil, inside tertiary hospitals or universities. Among the initiatives advanced by these centers, there are partnerships with the public educational system and other community-based efforts toward knowledge transfer. On the other hand, several challenges remain to be overcome, especially in relation to their expansion, which is necessary to match the existing demand.

MÉTODO: Foi realizada uma busca na internet compreendendo os websites de sociedades médicas e das principais universidades e artigos publicados por autores latino-americanos e os resultados foram discutidos criticamente. RESULTADOS: Os países latino-americanos são profundamente deficientes no que diz respeito a serviços especializados de intervenção precoce em psicose. Nossa busca encontrou sete serviços principais, quatro dos quais baseados em áreas urbanas do Brasil, dentro de hospitais terciários ou universidades. Dentre as iniciativas promovidas por esses centros, há parcerias com o sistema público de educação e outros esforços baseados na comunidade para transferência de conhecimento. Não obstante, vários desafios ainda devem ser superados, relacionados sobretudo à expansão de tais serviços, necessária para abarcar a demanda existente.
