conferenceObject DETECTING DISSONANCE IN CLINICAL AND RESEARCH WORKFLOWS FOR TRANSLATIONAL PSYCHIATRIC REGISTRIES(2012) COFIEL, Luciana; BASSI, Debora; PIETROBON, Ricardo; BRENTANI, HelenaData capture process is an important step in health care research, but it often receives little attention on research design number of flaws. To the best of our knowledge, no previous studies have developed standards that would allow for the comparison of workflow models of clinical and research activities and the improvement of the data collection process. In the present study we developed workflow models for a translational research study in psychiatry and for the clinic where it was implemented. Models were used for workflow comparison and identification of dissonances between both, qualitative standards and a corresponding taxonomy arose and workflow re-engineering was proposed and implemented.bookPart Sintomas comportamentais associados às demências(2021) BASSITT, Débora Pastore; FOLQUITTO, Jefferson Cunha; PENTEADO, Camila Truzzi; SILVEIRA, Jorge Augusto Alves- Patterns of regional gray matter loss at different stages of schizophrenia: A multisite, cross-sectional VBM study in first-episode and chronic illness(2016) TORRES, Ulysses S.; DURAN, Fabio L. S.; SCHAUFELBERGER, Maristela S.; CRIPPA, Jose A. S.; LOUZA, Mario R.; SALLET, Paulo C.; KANEGUSUKU, Caroline Y. O.; ELKIS, Helio; GATTAZ, Wagner F.; BASSITT, Debora P.; ZUARDI, AntonioW.; HALLAK, Jaime Eduardo C.; LEITE, Claudia C.; CASTRO, Claudio C.; SANTOS, Antonio Carlos; MURRAY, Robin M.; BUSATTO, Geraldo F.Background: Structural brain abnormalities in schizophrenia have been repeatedly demonstrated in magnetic resonance imaging (MRI) studies, but it remains unclear whether these are static or progressive in nature. While longitudinalMRI studies have been traditionally used to assess the issue of progression of brain abnormalities in schizophrenia, information from cross-sectional neuroimaging studies directly comparing first-episode and chronic schizophrenia patients to healthy controls may also be useful to further clarify this issue. With the recent interest in multisite mega-analyses combining structural MRI data from multiple centers aiming at increased statistical power, the present multisite voxel-basedmorphometry (VBM) studywas carried out to examine patterns of brain structural changes according to the different stages of illness and to ascertainwhich (if any) of such structural abnormalities would be specifically correlated to potential clinical moderators, including cumulative exposure to antipsychotics, age of onset, illness duration and overall illness severity. Methods: Wegathered a large sample of schizophrenia patients (161, being 99 chronic and 62 first-episode) and controls (151) fromfour previousmorphometricMRI studies (1.5 T) carried out in the same geographical region of Brazil. Image processing and analyses were conducted using Statistical Parametric Mapping (SPM8) software with the diffeomorphic anatomical registration through exponentiated Lie algebra (DARTEL) algorithm. Group effects on regional gray matter (GM) volumes were investigated through whole-brain voxel-wise comparisons using General LinearModel Analysis of Co-variance (ANCOVA), always including total GMvolume, scan protocol, age and gender as nuisance variables. Finally, correlation analyseswere performed between the aforementioned clinical moderators and regional and global brain volumes. Results: First-episode schizophrenia subjects displayed subtle volumetric deficits relative to controls in a circumscribed brain regional network identified only in small volume-corrected (SVC) analyses (p < 0.05, FWE-corrected), including the insula, temporolimbic structures and striatum. Chronic schizophrenia patients, on the other hand, demonstrated an extensive pattern of regional GM volume decreases relative to controls, involving bilateral superior, inferior and orbital frontal cortices, right middle frontal cortex, bilateral anterior cingulate cortices, bilateral insulae and right superior and middle temporal cortices (p < 0.05, FWE-corrected over the whole brain). GM volumes in several of those brain regionswere directly correlated with age of disease onset on SVC analyses for conjoined (first-episode and chronic) schizophrenia groups. There were also widespread foci of significant negative correlation between duration of illness and relative GM volumes, but such findings remained significant only for the right dorsolateral prefrontal cortex after accounting for the influence of age of disease onset. Finally, significant negative correlations were detected between life-time cumulative exposure to antipsychotics and total GM and white matter volumes in schizophrenia patients, but no significant relationship was found between indices of antipsychotic usage and relative GM volume in any specific brain region. Conclusion: The above data indicate that brain changes associated with the diagnosis of schizophrenia are more widespread in chronic schizophrenia compared to first-episode patients. Our findings also suggest that relative GM volume deficits may be greater in (presumably more severe) cases with earlier age of onset, as well as varying as a function of illness duration in specific frontal brain regions. Finally, our results highlight the potentially complex effects of the continued use of antipsychotic drugs on structural brain abnormalities in schizophrenia, as we found that cumulative doses of antipsychotics affected brain volumes globally rather than selectively on frontal-temporal regions.

- Cortical surface abnormalities are different depending on the stage of schizophrenia: A cross-sectional vertexwise mega-analysis of thickness, area and gyrification(2021) ROSA, Pedro Gomes Penteado; ZUGMAN, Andre; CERQUEIRA, Carlos Toledo; SERPA, Mauricio Henriques; DURAN, Fabio Luis de Souza; ZANETTI, Marcus Vinicius; BASSITT, Debora Pastore; ELKIS, Helio; CRIPPA, Jose Alexandre S.; SALLET, Paulo Clemente; GATTAZ, Wagner Farid; HALLAK, Jaime Eduardo Cecilio; LOUZA, Mario Rodrigues; GADELHA, Ary; JACKOWSKI, Andrea Parolin; BRESSAN, Rodrigo Affonseca; BUSATTO FILHO, GeraldoBackground: Brain magnetic resonance imaging studies have not investigated the cortical surface comprehensively in schizophrenia subjects by assessing thickness, surface area and gyrification separately during the first episode of psychosis (FEP) or chronic schizophrenia (ChSch). Methods: We investigated cortical surface abnormalities in 137 FEP patients and 240 ChSch subjects compared to 297 Healthy Controls (HC) contributed by five cohorts. Maps showing results of vertexwise between-group comparisons of cortical thickness, area, and gyrification were produced using T1-weighted datasets processed using FreeSurfer 5.3, followed by validated quality control protocols. Results: FEP subjects showed large clusters of increased area and gyrification relative to HC in prefrontal and insuli cortices (Cohen's d: 0.049 to 0.28). These between-group differences occurred partially beyond the effect of sample. ChSch subjects displayed reduced cortical thickness relative to HC in smaller fronto-temporal foci (d:-0.73 to-0.35), but not beyond the effect of sample. Differences between FEP and HC subjects were associated with male gender, younger age, and earlier illness onset, while differences between ChSch and HC were associated with treatment-resistance and first-generation antipsychotic (FGA) intake independently of sample effect. Conclusions: Separate assessments of FEP and ChSch revealed abnormalities that differed in regional distribution, phenotypes affected and effect size. In FEP, associations of greater cortical area and gyrification abnormalities with earlier age of onset suggest an origin on anomalous neurodevelopment, while thickness reductions in ChSch are at least partially explained by treatment-resistance and FGA intake. Associations of between-group differences with clinical variables retained statistical significance beyond the effect of sample.

METHODS: This is a cross-sectional, exploratory, and descriptive study with a quantitative approach. One hundred elderly patients were interviewed to apply a socioeconomic form and to assess alcohol consumption from AUDIT. RESULTS: correlation between alcohol consumption and female gender (p = 0.021). Most of the participants were between 60 and 79 years old, were female, had a partner, had completed elementary school, had income and selected house, were retired and unemployed. CONCLUSION: In the present study, we found no correlation between alcohol abuse and depression; Only one correlation was found between male gender and higher alcohol abuse. However, a significant prevalence of moderate use of high alcohol was found (3.9% in women and 21.7% in men), i.e., it poses a risk to the health of the elderly.

- Variation of plasma cortisol levels in patients with depression after treatment with bilateral electroconvulsive therapy(2015) BURGESE, Daniel Fortunato; BASSITT, Débora PastoreIntroduction: More than 60 years after the introduction of modern psychopharmacology, electroconvulsive therapy (ECT) continues to be an essential therapeutic modality in the treatment of mental disorders, but its mechanism of action remains unclear. Hormones play an essential role in the development and expression of a series of behavioral changes. One aspect of the influence of hormones on behavior is their potential contribution to the pathophysiology of psychiatric disorders and the mechanism of action of psychotropic drugs and ECT. Objective: We measured blood levels of the hormone cortisol in patients with unipolar depression according to the Diagnostic and Statistical Manual of Mental Disorders, 4th edition (DSM-IV) and compared results with levels found in healthy adults. Method: Blood cortisol levels were measured before the beginning of treatment with ECT, at the seventh session, and at the last session, at treatment completion. Depression symptoms were assessed using the Beck Depression Inventory (BDI). Results: Cortisol levels remained stable in both men and women between the seventh and the last sessions of ECT; values ranged from 0.686±9.6330 g/dL for women, and there was a mean decrease of 5.825±6.0780 g/dL (p = 0.024). Mean number of ECT sessions was 12. After the seventh and the last ECT sessions, patients with depression and individuals in the control group had similar cortisol levels, whereas BDI scores remained different. Conclusion: Cortisol levels decreased during ECT treatment. ECT seems to act as a regulator of the hypothalamic-pituitaryadrenal axis.
