The role of childhood cumulative trauma in the risk of lifetime PTSD: An epidemiological study.

Cumulative trauma is usually devastating and can lead to severe psychological consequences, including posttraumatic stress disorder (PTSD). Exposure to various types of traumas, particularly during childhood, can be even more deleterious than the sheer number of events experienced. This epidemiological study is the first to investigate the impact of discrete childhood traumatic exposure on the risk of developing lifetime PTSD in a representative sample of the general population of the two biggest Brazilian cities. Participants were aged between 15 and 75 years old, living in São Paulo and Rio de Janeiro, Brazil, who had experienced traumatic events (N = 3,231). The PTSD diagnosis was assessed using the DSM-IV criteria through the version 2.1 of Composite International Diagnostic Interview. To operationalize childhood cumulative trauma, we considered the sum of 15 different childhood trauma categories that occurred before PTSD onset. The final multivariate logistic regression model indicated a strong relationship between the number of discrete types of childhood traumas and the likelihood of the lifetime PTSD development. The lifetime PTSD risk increased 28 % with each different type of childhood trauma when adjusted by confounds. Our study strengthens the evidence associating childhood cumulative trauma to increased lifetime PTSD risk.

Exploring the Acquisition of Social Communication Skills in Children with Autism: Preliminary Findings from Applied Behavior Analysis (ABA), Parent Training, and Video Modeling.

Social communication skills, especially eye contact and joint attention, are frequently impaired in autism spectrum disorder (ASD) and predict functional outcomes. Applied behavior analysis is one of the most common evidence-based treatments for ASD, but it is not accessible to most families in low- and middle-income countries (LMICs) as it is an expensive and intensive treatment and needs to be delivered by highly specialized professionals. Parental training has emerged as an effective alternative. This is an exploratory study to assess a parental intervention group via video modeling to acquire eye contact and joint attention. Four graded measures of eye contact and joint attention (full physical prompt, partial physical prompt, gestural prompt, and independent) were assessed in 34 children with ASD and intellectual disability (ID). There was a progressive reduction in the level of prompting required over time to acquire eye contact and joint attention, as well as a positive correlation between the time of exposure to the intervention and the acquisition of abilities. This kind of parent training using video modeling to teach eye contact and joint attention skills to children with ASD and ID is a low-cost intervention that can be applied in low-resource settings.

The impact of inflammatory and metabolic markers on depression, anxiety, and cognition after COVID-19: A narrative review.

INTRODUCTION: There has been growing concern about the long-term effects of COVID-19 on mental health. The biological factors common to psychiatric conditions and COVID-19 are not yet fully understood. METHODOLOGY: We narratively reviewed prospective longitudinal studies that measured metabolic or inflammatory markers and assessed psychiatric sequalae and cognitive impairment in individuals with COVID-19 at least 3 months after the infection. A literature search identified three relevant cohort studies. RESULTS: Overall, depressive symptomatology and cognitive deficits persisted for up to one year after COVID-19; depression and cognitive changes were predicted by acute inflammatory markers, and changes in these markers correlated with changes in depressive symptomatology; female sex, obesity, and the presence of inflammatory markers were associated with more severe clusters of physical and mental health status in patients' self-perceived recovery; and plasma metabolic profiles of patients continued to differ from those of healthy controls three months after hospital discharge, which were associated with widespread alterations in neuroimaging, reflecting issues with white matter integrity. This is a non-systematic review and cautions should be made while interpreting the conclusions. CONCLUSION: In individuals affected by the COVID-19, prolonged exposure to stress and alterations in metabolic and inflammatory markers plays a central role in psychiatric sequalae and cognitive deficits in the long term.

Adaptation to Brazilian Portuguese and Latin-American Spanish and psychometric properties of the Mental Illness Clinicians' Attitudes Scale (MICA v4).

OBJECTIVE: To describe translation to Spanish and Portuguese and adaptation of the Mental Illness Clinicians' Attitudes Scale version 4 (MICA v4). METHODS: The questionnaire was administered to primary care physicians (PCPs) from four Latin-American countries, Brazil, Bolivia, Chile, and Cuba. The validation process included four phases: 1) translation of the questionnaire to Spanish and Portuguese; 2) assessment of face validity; 3) assessment of reliability; and 4) evaluation of construct validity with confirmatory factor analysis (CFA). RESULTS: The study sample comprised 427 PCPs. The mean age of the Spanish-speaking sample (n = 252) was 40.1 (S.D = 9.7) years and the mean age of the Portuguese-speaking sample (n = 150) was 40.2 (S.D = 10.9) years. Both models demonstrated "appropriate" internal reliability. Total omega was 0.91 for the Spanish-speaking sample and 0.89 for the Portuguese-speaking sample. The CFA of both questionnaires showed an appropriate fit for a three-factor model (Portuguese: CFI = 0.927; TLI = 0.913; RMSEA = 0.066; Spanish: CFI = 0.945; TLI = 0.935; RMSEA = 0.068). CONCLUSION: The Latin-American versions of the MICA v4 in Spanish and Brazilian Portuguese have appropriate psychometric properties, good internal consistency, and are applicable to and acceptable in the Latin-American context. The instrument proved its validity for collecting data on stigmatizing attitudes among health professionals in different contexts and cultures.

Community Health Workers' Knowledge, Attitudes, and Practices towards Epilepsy in Sofala, Central Mozambique.

BACKGROUND: Epilepsy is the most common neurological disease in the world, affecting 50 million people, with the majority living in low- and middle-income countries (LMICs). A major focus of epilepsy treatment in LMICs has been task-sharing the identification and care for epilepsy by community health workers (CHWs). The present study aimed to assess the knowledge, attitudes, and practices (KAPs) of CHWs towards epilepsy in Mozambique. METHODS: One hundred and thirty-five CHWs completed a questionnaire that included socio-demographic characteristics and 44-items divided into six subscales pertaining to KAPs towards epilepsy (QKAP-EPI) across nine districts of Sofala, Mozambique. The internal consistency was examined to evaluate the reliability of the instrument (QKAP-EPI). The association between sociodemographic variables and QKAP-EPI subscales was examined using linear regression models. RESULTS: The internal consistency was moderate for two subscales (causes of epilepsy, α = 0.65; medical treatment, α = 0.694), acceptable for cultural treatment (α = 0.797) and excellent for 2 subscales (safety and risks, α = 0.926; negative attitudes, α = 0.904). Overall, CHWs demonstrated accurate epilepsy knowledge (medical treatment: mean = 1.63, SD = 0.28; safety/risks: mean = 1.62, SD = 0.59). However, CHWs reported inaccurate epilepsy knowledge of the causes, negative attitudes, as well as culturally specific treatments for epilepsy, such as: "if a person with epilepsy burns when set on fire they cannot be treated". Knowledge about how to manage epileptic seizures varied across the different emergency care practices, from the accurate belief that it is not advisable to place objects in the individual's mouth during an epileptic seizure, to the wrong perception of the need to hold the person in seizures to control seizures. Heterogeneity in the level of epilepsy knowledge was observed among CHWs, when considering epilepsy according to the local names as treatable ("Dzumba") and other forms as untreatable ("Nzwiti"). CONCLUSION: CHWs knowledge of medical treatment and epilepsy safety/risks were adequate. However, information on the causes of epilepsy, stigmatizing attitudes, cultural treatment, and some knowledge of epileptic seizure management were low. These areas of poor knowledge should be the focus of educating CHWs in increasing their ability to provide quality care for patients with epilepsy in Mozambique.

Utilisation and costs of mental health-related service use among adolescents.

BACKGROUND: The high level of care needs for adolescents with mental health conditions represents a challenge to the public sector, especially in low and middle-income countries. We estimated the costs to the public purse of health, education, criminal justice and social care service use associated with psychiatric conditions among adolescents in Brazil; and examined whether the trajectory of psychopathology and its impact on daily life, and parental stigma towards mental illness, was associated with service utilisation and costs. METHODS: Data on reported service use among adolescents from a prospective community cohort (n = 1,400) were combined with Brazilian unit costs. Logistic regression and generalised linear models were used to examine factors associated with service use and associated costs, respectively. RESULTS: Twenty-two percent of those who presented with a psychiatric disorder used some type of service for their mental health in the previous twelve months. Higher odds of service use were associated with having a diagnosed mental disorder (either incident, [OR = 2.49, 95%CI = 1.44-4.30, p = 0.001], remittent [OR = 2.16, 95%CI = 1.27-3.69, p = 0.005] or persistent [OR = 3.01, 95%CI = 1.69-5.36, p<0.001]), higher impact of symptoms on adolescent's life (OR = 1.32, 95%CI = 1.19-1.47, p<0.001) and lower parental stigma toward mental illness (OR = 1.12, 95%CI = 1.05-1.20, p = 0.001). Average annual cost of service use was 527.14 USD (s.d. = 908.10). Higher cost was associated with higher disorder impact (ß = 0.25, 95%CI = 0.12-0.39, p<0.001), lower parental stigma (ß = 0.12, 95%CI = 0.02-0.23, p = 0.020) and white ethnicity (ß = 0.55, 95%CI = 0.04-1.07, p = 0.036). CONCLUSION: The impact of mental health problems on adolescents' daily lives and parental stigmatising attitudes toward mental illness were the main predictors of both service use and costs.

Perceptions of Community Health Workers (CHW) on barriers and enablers to care for people with psychosis in rural Mozambique: findings of a focus group discussion study using the Capability, Opportunity, Motivation and Behaviour framework (COM-B framework).

BACKGROUND: Psychotic disorders contribute significantly to the global disease burden by causing disability, impaired quality of life, and higher mortality in affected people compared with the general population. In rural settings, where there is limited or no access to healthcare, individuals living with psychotic disorders often seek support from Community Health Workers (CHWs). However, little is known about what CHWs know about psychosis and how they manage such cases. This study aimed to explore the CHWs perception of psychosis and their experiences and beliefs about the factors that might enable or hinder care-taking for patients with psychosis in rural settings in Mozambique. METHODS: A qualitative study was conducted in rural districts of Maputo Province, a southern region of Mozambique, using six focus group discussions with participation of 79 CHWs. Thematic analysis was used informed by the Capabilities, Opportunities, Motivation and Behaviour framework (COM-B). RESULTS: Nine primary themes were identified. Overall, CHWs perceived psychosis as treatable medical conditions and held a positive attitude about being part of the care-taking process of patients with psychosis in rural settings. Partnerships with key-stakeholders such as traditional healers, health care workers, and families, were perceived by CHWs as enablers to improve access to care in rural areas. However, stigma, myths, and lack of competencies to treat people with psychosis were perceived by CHWs as barriers for appropriate care. CONCLUSION: CHWs, with adequate support, could play an important role in the care of patients with psychosis in rural settings, including identifying patients requiring care and referring them to appropriate healthcare professionals, and following up medicated patients with psychosis. Training of CHWs should consider inclusion of basic mental health care competencies.

Management of common mental disorders should take place in primary health or specialized care? Clinical decisions of psychiatrists from Latin American countries.

OBJECTIVE: The objective of our study was to explore clinical decisions of psychiatrists regarding the management of common mental disorders in primary care (PC) in four Latin Americans countries, through the application of clinical vignettes. METHODS: Using a cross-sectional design, we conducted a self-administered online questionnaire survey of psychiatrists from Bolivia, Brazil, Cuba, and Chile. The questionnaire covered sociodemographic and professional information. The psychiatrists' clinical decisions were assessed through three clinical vignettes representing typical PC cases of depression, anxiety, and somatization. RESULTS: 230 psychiatrists completed the online survey. Psychiatrists from Brazil were less likely to recognize depression as a mental disorder than those from Cuba (odds ratio (OR) = 0.30, 95% confidence interval (CI), 0.10 to 0.91, p < 0.04). Female gender (OR = 0.19, 95% CI, 0.04 to 0.91, p < 0.02) and older age (OR = 0.92, 95% CI, 0.87 to 0.97, p < 0.01) reduced the likelihood of agreement that depression cases should be treated by a Primary Care Physician (PCP). In the somatoform symptoms vignette, longer training duration increased the likelihood of agreement that treatment should be done by a psychiatrist instead of a PCP (OR = 1.19, 95% CI, 1.04 to 1.37, p < 0.01). In the anxiety vignette, females (OR = 2.38, 95% CI, 1.10 to 5.13, p < 0.01) and participants from Bolivia (compared with Cubans, OR = 4.19, 95% CI, 1.22 to 14.42, p < 0.02) were more likely to consider that these patients should be treated by a psychiatrist instead of a PCP. DISCUSSION: Most psychiatrist respondents agreed that patients with depression should be treated by PCPs and that somatoform and anxiety cases should be treated by psychiatrists. These results show that psychiatrists consider that they, and not PCPs, should treat patients with common mental disorders, regardless of the evidence showing that common mental disorders can be treated by primary care physicians in PC.

Impact of Repeated Doses of Subcutaneous Esketamine on Acute Dissociative Symptoms in Treatment-Resistant Depression.

BACKGROUND: Esketamine has been approved by the US Food and Drug Administration (FDA) as an adjunctive treatment for use in conjunction with an oral antidepressant for patients with treatment-resistant depression (TRD), but dissociative symptoms are common adverse effects. METHODS: A retrospective analysis of 394 subcutaneous esketamine injections given to 70 patients with TRD that were administered once a week during a six-week trial in conjunction with oral antidepressant therapy. Doses between 0.5 to 1.0 mg/kg were administered according to the patient's response. Dissociative symptoms were assessed using the Clinician-Administered Dissociative States Scale (CADSS) 30 and 60 min after every weekly treatment (day 1, 8, 15, 22, 29 and 36). RESULTS: Seventy patients received a total of 394 subcutaneous esketamine injections over six weeks. Over time, the evolution of CADSS scores demonstrated a significant mean difference of CADSS at 60 min post-injection (p = 0.010) throughout the six infusions. The mean CADSS scores at 60 min on day 22, 29 and 36 were similar. There were no differences between mean CADSS scores 30 min after the injections, no clinical correlation between response and dissociative symptoms, no correlation between time and demographic and clinical characteristics and no interactions between time and combined medication. CONCLUSIONS: Our results suggest that repeated subcutaneous esketamine doses are safe and well-tolerated regarding their acute dissociative and psychotomimetic symptoms. Symptoms usually peak at 30 min and decrease at 60 min post-injection, returning to their pretreatment levels at 120 min. Dissociative symptoms do not correlate with antidepressant response.

Latent structure and factor reliability of the National Health Service Community Mental Health Service User Questionnaire.

BACKGROUND: National Health Service use the Community Mental Health Service User Questionnaire (NHS-CMH) to assess care quality. However, its reliability and internal validity is uncertain. AIMS: To test the NHS-CMH structure, reliability and item-level characteristics. METHODS: We used data from 11,373 participants who answered the 2017 NHS-CMH survey. First, we estimated the NHS-CMH structure using Exploratory Factor Analysis (EFA) in half of the dataset. Second, we tested the best EFA-derived model with Confirmatory Factor Analysis (CFA). We tested the internal validity, construct reliability (omega - ω), explained common variance of each factor (ECV), and item thresholds. RESULTS: EFA suggested a 4-factor solution. The structure derived from the EFA was confirmed, demonstrating good reliability for the four correlated dimensions: "Relationship with Staff" (ω = 0.952, ECV = 40.1%), "Organizing Care" (ω = 0.855, ECV = 21.4%), "Medication and Treatments" (ω = 0.837, ECV = 13.3%), and "Support and Well-being" (ω = 0.928, ECV = 25.3%). A second-order model with a high-order domain of "Quality of Care" is also supported. CONCLUSIONS: The NHS-CMH can be used to reliably assess four user-informed dimensions of mental health care quality. This model offers an alternative for its current use (item-level and untested sum scores analysis).

The impact of child psychiatric conditions on future educational outcomes among a community cohort in Brazil.

AIMS: Mental health problems early in life can negatively impact educational attainment, which in turn have negative long-term effects on health, social and economic opportunities. Our aims were to: (i) estimate the impacts of different types of psychiatric conditions on educational outcomes and (ii) to estimate the proportion of adverse educational outcomes which can be attributed to psychiatric conditions. METHODS: Participants (N = 2511) were from a school-based community cohort of Brazilian children and adolescents aged 6-14 years enriched for high family risk of psychiatric conditions. We examined the impact of fear- (panic, separation and social anxiety disorder, specific phobia, agoraphobia and anxiety conditions not otherwise specified), distress- (generalised anxiety disorder, major depressive disorder and depressive disorder not otherwise specified, bipolar, obsessive-compulsive, tic, eating and post-traumatic stress disorder) and externalising-related conditions (attention deficit and hyperactivity disorder, conduct and oppositional-defiant conditions) on grade repetition, dropout, age-grade distortion, literacy performance and bullying perpetration, 3 years later. Psychiatric conditions were ascertained by psychiatrists, using the Development and Well-Being Behaviour Assessment. Propensity score and inverse probability weighting were used to adjust for potential confounders, including comorbidity, and sample attrition. We calculated the population attributable risk percentages to estimate the proportion of adverse educational outcomes in the population which could be attributed to psychiatric conditions. Analyses were conducted separately for males and females. RESULTS: Fear and distress conditions in males were associated with school dropout (odds ratio (OR) = 2.76; 95% confidence interval (CI) = 1.06, 7.22; p < 0.05) and grade repetition (OR = 2.76; 95% CI = 1.32, 5.78; p < 0.01), respectively. Externalising conditions were associated with grade repetition in males (OR = 1.66; 95% CI = 1.05, 2.64; p < 0.05) and females (OR = 2.03; 95% CI = 1.15, 3.58; p < 0.05), as well as age-grade distortion in males (OR = 1.66; 95% CI = 1.05, 2.62; p < 0.05) and females (OR = 2.88; 95% CI = 1.61, 5.14; p < 0.001). Externalising conditions were also associated with lower literacy levels (ß = -0.23; 95% CI = -0.34, -0.12; p < 0.001) and bullying perpetration (OR = 3.12; 95% CI = 1.50, 6.51; p < 0.001) in females. If all externalising conditions were prevented or treated, we estimate that 5.0 and 4.8% of grade repetition would not have occurred in females and males, respectively, as well as 10.2 (females) and 5.3% (males) of age-grade distortion cases and 11.4% of female bullying perpetration. CONCLUSIONS: The study provides evidence of the negative impact of psychiatric conditions on educational outcomes in a large Brazilian cohort. Externalising conditions had the broadest and most robust negative impacts on education and these were particularly harmful to females which are likely to limit future socio-economic opportunities.

Nationwide use of psychotropic drugs for treatment of self-reported depression in the Brazilian urban adult population.

OBJECTIVE: Antidepressant use is increasing worldwide, but national data on psychotropic drug use by depressed patients in Brazil is lacking. METHODOLOGY: Between 2013 and 2014, a representative sample of urban adult individuals were asked if they had a diagnosis of chronic disease, had a medical indication for drug treatment, and were taking chronic medications at the time for each reported diagnosis. We analyzed the frequencies of reported depression and the medications related to this disease. RESULTS: Overall, 6.1% of respondents reported depression. The prevalence increased with age - 9.5% among the elders - was higher among women (8.9%) and in the south of the country (8.9%). As a single disease, the prevalence of depression was higher among young people (17.6%). Among those with multimorbidity, the prevalence of depression rose to 25.7%. Of those who reported depression, 81.3% had medical indication for treatment and 90.3% were under treatment - this proportion was lower among young people (84.5%) and those living in the poorest region (78.6%). Antidepressants accounted for 47.2% of psychotropic drugs taken by respondents with depression, with regional differences - only 30% used antidepressants in the North. Polypharmacy was reported by 22% of those with depression and other chronic diseases. CONCLUSION: Depression in Brazil, is common among young adults as a single chronic disease and highly prevalent among people with chronic multimorbidity, especially the young. The treatment gap was larger among young people and in the less developed regions of the country.

Domestic violence and risk of internalizing and externalizing problems in adolescents living with relatives displaying substance use disorders / Violência doméstica e risco de problemas de internalização e externalização em adolescentes com familiares apresentando transtornos por uso de substâncias

OBJECTIVE: To investigate the association between exposure to domestic violence and increased risk of internalizing and externalizing problems and substance use among adolescents living with relatives with substance use disorder (SUD) at a low-income community of São Paulo, Brazil. METHODS: A crosssectional study was conducted with 102 adolescents aged 12-17 years (M = 14.2, SD = 1.7) who were living with relatives suffering from SUD. Outcomes were measured using the Youth Self-Report (YSR), psychosocial stress factors questionnaire, Drug Use Screening Inventory (DUSI) and Phrase Inventory of Intrafamily Child Abuse (PIICA). RESULTS: The sample presented high prevalence of emotional/behavioral problems with YSR's scores in the clinical range for Internalizing Problems (24.5%), Externalizing Problems (21.6%), and Total Problems (26.5%). The presence of mental health problems predicted substance use (PR = 2.22; 95% CI = 1.2-4.13), and substance use predicted increased risk of mental health problems. Alcohol use predicted more than double the risk of emotional/behavioral problems (PR = 2.01; 95% CI = 1.08-3.76), while illicit drug use was associated with an almost threefold increase in the prevalence of Internalizing (PR = 2.87; 95% CI = 1.19-6.89) and Externalizing Problems (PR = 3.3; 95% CI = 1.35-8.04). CONCLUSION: Adolescents of relatives with SUD are at risk of developing emotional and behavioral problems. These findings reinforce the need to develop public mental health policies, which include protective interventions to adolescents living in families affected by substance use disorders.

OBJETIVO: Investigar a associação entre exposição à violência doméstica e aumento do risco de problemas internalizantes e externalizantes e uso de substâncias entre adolescentes que vivem em famílias com transtorno por uso de substâncias (TUS) em uma comunidade de baixa renda de São Paulo, Brasil. MÉTODOS: Estudo transversal com 102 adolescentes de 12 a 17 anos (M = 14,2, DP = 1,7) que vivem com familiares com TUS. Os desfechos foram avaliados por meio do Inventário de Autoavaliação para Adolescentes (YSR), questionários de fatores de estresse psicossociais, Drug Use Screening Inventory (DUSI) e Inventário de Frases de Violência Doméstica (IFVD). RESULTADOS: A amostra apresentou altas taxas de problemas emocionais/comportamentais no YSR, sendo 24,5% com escores na faixa clínica para Problemas Internalizantes, 21,6% para Problemas Externalizantes e 26,5% para Problemas Totais. A presença de problemas de saúde mental foi preditora do uso de substâncias (RP = 2,22; IC 95% = 1,2-4,13) e o uso de substâncias foi preditor do aumento da prevalência de problemas emocionais/comportamentais. O uso de álcool prediz mais do que o dobro do risco de problemas emocionais/comportamentais (RP = 2,01; IC 95% = 1,08-3,76), enquanto o uso de substâncias ilícitas esteve associado com um aumento de quase três vezes na prevalência de Problemas Internalizantes (RP = 2,87; IC 95% = 1,19-6,89) e Externalizantes (RP = 3,3; IC 95% = 1,35-8,04). CONCLUSÃO: Adolescentes que convivem diretamente com familiares com TUS estão em risco para o desenvolvimento de problemas emocionais/comportamentais. Os achados reforçam a necessidade de políticas públicas que incluam programas de proteção para adolescentes que vivem em famílias com transtornos causados pelo uso de substâncias.

Comorbidity in post-traumatic stress disorder: A population-based study from the two largest cities in Brazil.

BACKGROUND: This study investigated the patterns of comorbidity between PTSD and depression, other anxiety disorders, alcohol-related disorders using the DSM-IV and ICD-10 criteria. The temporal sequence of the comorbid diagnoses was also investigated. METHODS: We used data from a large population-based survey carried out between 2007 and 2008 in the two largest cities in Brazil: São Paulo and Rio de Janeiro. RESULTS: Diagnoses of depression, other anxiety disorders, and alcohol-related disorder were more prevalent in the people with PTSD than in those without PTSD. Using the DSM-IV criteria, approximately 67% of cases presenting PTSD were also diagnosed with another mental disorder. The diagnosis category of other anxiety disorders presented the highest proportion of comorbidity (53%). Depression was found in 34% person with PTSD whilst alcohol-related disorders were observed in 7%. Considering the temporal relationship, the onset of comorbid depression was uniformly distributed through the periods before, within the same year and after PTSD's onset. When other anxiety disorders were comorbid with PTSD, in almost 90% of the cases the other anxiety disorders preceded PTSD. For comorbidity between of alcohol-related disorders and PTSD, in 50% of the cases alcohol-related disorders preceded the diagnosis of PTSD. LIMITATIONS: The cross-sectional design imposes limitations on establishing a temporal relationship between the onset of psychiatric disorders due to memory bias. CONCLUSIONS: Our findings indicate that among individuals presenting comorbid PTSD and other anxiety disorders, this diagnosis tend to precede PTSD. Comorbid cases are more frequent and more severe, and this should be taken into account in therapeutic research and clinical practice.

Nationwide use of psychotropic drugs for treatment of self-reported depression in the Brazilian urban adult population / Uso nacional de drogas psicotrópicas no tratamento da depressão autorreferida na população adulta urbana brasileira

RESUMO: Objetivo: O uso de antidepressivos está aumentando em todo o mundo, mas faltam dados nacionais sobre o uso de drogas psicotrópicas por pacientes deprimidos no Brasil. Metodologia: Entre 2013 e 2014, uma amostra representativa de indivíduos adultos urbanos foi questionada sobre a presença diagnóstica de doença crônica, a indicação médica para tratamento medicamentoso e o uso de medicamentos crônicos à época de cada diagnóstico relatado. Foram analisadas as frequências de depressão relatada e os medicamentos relacionados a essa doença. Resultados: No geral, 6,1% dos entrevistados relataram depressão. A prevalência aumentou com a idade (9,5% entre os idosos) foi maior entre as mulheres (8,9%) e no sul do país (8,9%). Como doença única, a prevalência de depressão foi maior entre os jovens (17,6%). Entre aqueles com multimorbidade, a prevalência de depressão subiu para 25,7%. Dos que relataram depressão, 81,3% tinham indicação médica para tratamento e 90,3% estavam em tratamento - essa proporção foi menor entre os jovens (84,5%) e os que moram na região mais pobre (78,6%). Os antidepressivos representaram 47,2% dos medicamentos psicotrópicos tomados pelos entrevistados com depressão, com diferenças regionais - apenas 30% usavam antidepressivos no Norte. Polifarmácia foi relatada por 22% das pessoas com depressão e outras doenças crônicas. Conclusão: A depressão no Brasil é comum entre adultos jovens como doença crônica única e altamente prevalente entre as pessoas com multimorbidade crônica, principalmente os jovens. A lacuna de tratamento foi maior entre os jovens e nas regiões menos desenvolvidas do país.

Differences Between Self-Reported Psychotic Experiences, Clinically Relevant Psychotic Experiences, and Attenuated Psychotic Symptoms in the General Population.

Purpose: Psychotic experiences in childhood (such as hearing voices or being suspicious) represent an important phenotype for early intervention. However, these experiences can be defined in several ways: self-reported psychotic experiences (SRPE) rely exclusively on the child's report, clinically validated psychotic experiences (CRPE) are based on clinical assessment, and attenuated psychotic symptoms (APS) represents a categorization to do with clinical relevance in relation to severity. Very few studies have investigated how these distinctions impact clinical and other domains. The present study aims to compare SRPE, CRPE, and APS among children and adolescents. Methods: This study is part of the Brazilian High-Risk Cohort Study for Psychiatric Disorders, in which 2,241 individuals aged 6-14 years provided self-ratings of 20 psychotic experiences using the Community Assessment of Psychic Experiences (CAPE). A trained psychologist conducted an interview to validate or reject reported experiences and to rate the presence of APS and affective flattening. In parallel, parents provided information about child mental health to an independent interviewer. We tested the association of mutually exclusive categories of non-validated SRPE (nSRPE), clinically validated PE below the threshold for APS (nCRPE), and APS (nSRPE = 33%, nCRPE = 11%, APS = 6%), with parents' information about the child's positive attributes and levels of psychopathology and psychologist assessment of blunted affect. Results: Most associations were qualitatively similar, and there was a dose-response in the strength of associations across categories, such that APS > nCRPE > nSRPE. Experiences in all three categories were associated with female sex. nSRPE were associated with overall levels of psychopathology, but to a lesser degree than nCRPE and APS. APS and nCRPE were associated with less positive attributes, with APS more so than nCRPE. Only APS was associated with affective flattening. Conclusions: In children and adolescents, SRPE, CRPE, and APS all index liability for psychopathology, but as clinician rated relevance increases, associations get stronger and become evident across more domains.

Association between psychosocial stressors with emotional and behavioral problems among children of low-income addicted families living in Brazil.

BACKGROUND: Children exposed to substance use in their families are vulnerable to multiple risk factors in their development and at increased risk for emotional and behavioral problems. The aims of the study were as follows 1) estimate the prevalence of emotional and behavioral problems among children aged 6-11 years old, living with addicted family members in a low-income urban community of São Paulo, Southeastern Brazil; 2) evaluate the children's exposure to family psychosocial stressors and substance use; and 3) investigate the factors related to the increased risk of emotional and behavioral problems and substance use. METHODS: A cross-sectional study was conducted among 101 children aged 6-11 years old (M = 9.16 years, SD = 1.61). The instruments used were a sociodemographic questionnaire, the Child Behavior Checklist (CBCL) and the Psychosocial Stress Factors (PSF). RESULTS: High prevalence of problems was found for this sample: the CBCL showed 26.7% of clinical scores for Internalizing Problems, 40.6% for Externalizing Problems, and 40.6% for Total Problems. Exposure to family psychosocial stressors was also high, including severe disease (33%), physical aggression (28.9%), death (27.8%), psychiatric hospitalization (16.7%), suicide attempts (15.5%), and suicide (9.3%). Exposure to these family stressors was associated with an increase of two to four times in the prevalence of internalizing and externalizing problems. CONCLUSIONS: Children exposed to substance abusers have more mental health problems than general population, even when compared to peers living in similar low-income areas. This is a group that should be target of a selective preventive intervention.

DGCR2 influences cortical thickness through a mechanism independent of schizophrenia pathogenesis.

We investigated the role of DGCR2, a corticogenesis-related gene, on schizophrenia (SZ) and its subphenotypes, including brain morphology. A total of 221 SZ patients, 263 controls and 70 antipsychotic-naïve first episode of psychosis (FEP) were genotyped for 17 DGCR2 polymorphisms. While no association between DGCR2 polymorphisms and SZ was found, the missense variant rs2072123 was associated to left rostral anterior cingulate thickness, showing that DGCR2 seems not to be associated directly with the SZ but might be influencing the brain morphology. We also showed a DGCR2 downregulation in SZ patients when compared to controls and FEP.
