Abstract Background Emerging evidence indicates that inflammation plays an important role as a mechanism underlying mental disorders. However, most of the research on inflammatory mechanisms focuses on serum levels of interleukins and very few studies have investigated molecules that initiate and expand innate immune pathways such as damage-associated molecular patterns (DAMPs). Objectives This study investigated the levels of DAMPs among patients diagnosed with major depressive disorder (MDD), bipolar disorder (BD) I and II, schizophrenia (SCZ), and generalized anxiety disorder (GAD). We quantified serum levels of heat shock proteins (HSPs) 70 and 60 and of S100 calcium-binding protein B (S100B). Methods Serum levels of HSP70, HSP60, and S100B were assessed in a sample of participants with psychiatric disorders (n = 191) and a control group (CT) (n = 59) using enzyme-linked immunosorbent assay (ELISA). Results Serum HSP70 concentrations were significantly higher in the MDD group compared to the CT, SCZ, and BD groups. The GAD group had higher concentrations of HSP70 than the SCZ group. Exploring associations with medications, lithium (p = 0.003) and clozapine (p = 0.028) were associated with lower HSP70 levels. Approximately 64% of the sample had DAMPs levels below the limits of detection indicated by the respective ELISA kit. Conclusion This was the first study to assess DAMPs levels in a transdiagnostic sample. Our preliminary findings suggest that HSP70 may be associated with MDD pathophysiology. Medications such as lithium and clozapine were associated with lower HSP70 levels in BD and SCZ groups, respectively. Therefore, it is worth mentioning that all participants were medicated and many psychotropic drugs exert an anti-inflammatory effect, possibly reducing the signs of inflammation.

Abstract Introduction Individuals with major depressive disorder (MDD) face more barriers to engagement in sports and exercise interventions. Evaluating clinical and demographic factors associated with adherence to sports and exercise among MDD outpatients could support development of new options and strategies to increase their participation. Methods In a cross-sectional study, 268 depressed outpatients were evaluated (83.51% females; mean age = 50.74 [standard deviation {SD} = 10.39]). Sports and exercise participation were assessed using a question about participation frequency during the previous month. Clinical and demographic factors were evaluated. Linear regression was used to identify predictors of participation in sports and exercise. Results MDD patients with mild symptoms of depression (odds ratio [OR] = 2.42; 95% confidence interval [95%CI] 1.00, 5.88; p = 0.04) and patients with mild to moderate symptoms (OR = 3.96; 95%CI 1.41, 11.15; p = 0.009) were more likely to engage regularly in sports and exercise than patients with more severe depression. Moreover, smoking (OR = 0.23; 95%CI 0.67, 0.80; p = 0.007) and being divorced (OR = 0.22; 95%CI 0.57, 0.86; p = 0.03) were associated with lower rates of engagement in sports and exercise. Conclusion Our findings indicate a significant association between clinical and demographic factors and participation in sports and exercise among MDD outpatients.

Abstract Introduction Depression is possibly not a single syndrome but rather comprises several subtypes. DSM-5 proposes a melancholia specifier with phenotypic characteristics that could be associated with clinical progression, biological markers or therapeutic response. The Sydney Melancholia Prototype Index (SMPI) is a prototypic scale aimed to improve the diagnosis of melancholia. So far, there is only an English version of the instrument available. The aim of this study is to describe the translation and adaptation of the English version of the SMPI into Brazilian Portuguese. Methods Translation and cross-cultural adaptation of the self-report (SMPI-SR) and clinician-rated (SMPI-CR) versions into Brazilian Portuguese were done following recommendations of the International Society for Pharmacoeconomics and Outcomes Research (ISPOR). This guideline includes the following steps: preparation, forward translation, reconciliation, back translation, back translation review, harmonization, cognitive debriefing, debriefing results review, proofreading and final report. Results The Brazilian Portuguese versions of the SMPI were well-accepted by respondents. Changes in about two-thirds of the items were considered necessary to obtain the final Brazilian Portuguese version of the SMPI. Conclusions Both versions of the SMPI are now available in Brazilian Portuguese. The instrument could become an important option to enhance studies on melancholia in Portuguese-speaking samples.

Resumo Os transtornos psiquiátricos são responsáveis por uma significativa carga de doença tanto no nível individual quanto na saúde pública. Mesmo com financiamento abaixo do ideal, muitas pesquisas de alta qualidade vêm sendo executadas em vários centros. Entretanto, o impacto desses estudos na prática clínica é menor que o esperado. A complexidade dos transtornos psiquiátricos é uma das razões pelas quais enfrentamos tanta dificuldade na translação dos resultados das pesquisas para a prática clínica. Novas tecnologias e metodologias aperfeiçoadas já estão disponíveis e devem ser incorporadas para lidar com esta complexidade e acelerar o processo translacional. Discuto, neste artigo, a aplicação de técnicas modernas para a coleta e análise de dados e as novas possibilidades para a realização de testes em modelos virtuais dos sistemas biológicos. A adoção das novas tecnologias é necessária, mas não reduzirá a importância de fundamentos da pesquisa em psiquiatria, como as perspectivas desenvolvimental e translacional. Os psiquiatras que desejarem integrar essas novas tecnologias à suas pesquisas terão que trabalhar com colaboradores com os quais não estão acostumados, como especialistas em informática, equipes multidisciplinares e representantes de partes interessadas nos resultados, como pacientes e provedores de cuidados assistenciais. Esse processo permitirá um avanço no conhecimento e no alívio do sofrimento e da incapacidade das pessoas com transtornos psiquiátricos.

Abstract Psychiatric disorders place considerable burden on individuals and on public health. Funding for research in psychiatry is less than ideal, but even so high quality research is being conducted at many centers. However, these studies have not impacted clinical practice as much as expected. The complexity of psychiatric disorders is one of the reasons why we face difficulties in translating research results to patient care. New technologies and improved methodologies are now available and must be incorporated to deal with this complexity and to accelerate the translational process. I discuss the application of modern techniques for data acquisition and analysis and also the new possibilities for performing trials in virtual models of biological systems. Adoption of new technologies is necessary, but will not reduce the importance of some of the fundamentals of all psychiatry research, such as the developmental and translational perspectives. Psychiatrists wishing to integrate these novelties into their research will need to work with contributors with whom they are unaccustomed to working, such as computer experts, a multidisciplinary team, and stakeholders such as patients and caregivers. This process will allow us to further understand and alleviate the suffering and impairment of people with psychiatric disorders.
