RESUMO

ABSTRACT Introduction: Chronic kidney disease (CKD) requires long-lasting treatments and severe changes in the routine of children, which may favor a low quality of life (QoL) and damage to their mental health and that of their primary caregivers (PC). The present study aimed to investigate the presence of anxiety and depression and to analyze the QoL of children and adolescents diagnosed with CKD at stages 3, 4, and 5, and their PC. Methods: We carried out an observational case-control study with 29 children and adolescents and their PC as the case group and 53 as the control group. International instruments, validated for the Brazilian population, were used: Child Anxiety Inventory (STAI-C), Pediatric Quality of Life Inventory (PEDSQL), Child Depression Inventory (CDI), Beck Anxiety and Depression Inventory (BAI; BDI), and the WHOQOL-bref. Results: The study identified statistically significant differences in the PEDSQL total score (control group, 72.7 ± 19.5; case group, 63.3 ± 20.6; p = 0.0305) and in the psychosocial (control group, 70.5 ± 20.5 and case group, 61.4 ± 19.7; p = 0.0420) and school health dimensions (control group, 72.9 ± 21.0 and case group, 55.2 ± 19.8; p = 0.0003) and the presence of psychiatric comorbidity (depression and anxiety symptoms) in the case group (p = 0.02). As for PC, the study showed statistical significance for the prevalence of depression (p = 0.01) and anxiety (p = 0.02) symptoms. Conclusion: Patients with CKD have lower QoL indices and more psychiatric comorbidities, and their PC are affected by the disease, with higher indices of depression and anxiety.

RESUMO Introdução: A doença renal crônica (DRC) requer tratamentos duradouros e alterações severas na rotina de crianças, o que pode favorecer baixa qualidade de vida (QV) e danos à sua saúde mental e à de seus cuidadores primários (CP). O presente estudo teve como objetivo investigar a presença de ansiedade e depressão e analisar a QV de crianças e adolescentes diagnosticados com DRC nos estágios 3, 4, 5, e seus CP. Métodos: Realizamos estudo observacional de caso-controle com 29 crianças e adolescentes e seus CP como grupo de casos e 53 como grupo controle. Utilizamos instrumentos internacionais, validados para a população brasileira: Inventário de Ansiedade Traço-Estado Infantil (IDATE-C), Questionário Pediatric Quality of Life (PEDSQL), Inventário de Depressão Infantil (CDI), Inventário de Ansiedade e Depressão de Beck (BAI; BDI), e o WHOQOL-bref. Resultados: O estudo identificou diferenças estatisticamente significativas no escore total do PEDSQL (grupo controle, 72,7 ± 19,5; grupo de casos, 63,3 ± 20,6; p = 0,0305), no psicossocial (grupo controle, 70,5 ± 20,5; grupo de casos, 61,4 ± 19,7; p = 0,0420), nas dimensões de saúde escolar (grupo controle, 72,9 ± 21,0; grupo de casos, 55,2 ± 19,8; p = 0,0003) e na presença de comorbidade psiquiátrica (sintomas de depressão e ansiedade) no grupo de casos (p = 0,02). Quanto aos CP, o estudo demonstrou significância estatística para a prevalência de sintomas de depressão (p = 0,01) e ansiedade (p = 0,02). Conclusão: Pacientes com DRC apresentam índices mais baixos de QV e mais comorbidades psiquiátricas, e seus CP são afetados pela doença, com índices maiores de depressão e ansiedade.

RESUMO

Resumo: Introdução: Médicos e alunos de Medicina são grupos de risco para o suicídio e comportamento suicida. Comportamentos suicidas abrangem fenômenos que vão desde pensamentos, planejamentos, tentativas e até a morte por suicídio. Sabe-se pouco sobre o comportamento suicida entre estudantes de Medicina brasileiros. Objetivo: Este estudo teve como objetivos avaliar a prevalência de ideação, planejamentos e tentativas suicidas em uma amostra de estudantes de graduação em Medicina do Brasil, e identificar os fatores sociodemográficos, de vida estudantil e de saúde mais associados a esses comportamentos. Método: Participaram do estudo 722 alunos do curso de Medicina da Unicamp, durante os anos de 2017 e 2018, que responderam de forma voluntária e anônima a um questionário amplo, que incluía dados sociodemográficos, de vida acadêmica e de comportamento suicida. A análise estatística foi realizada por meio do teste de qui-quadrado, do teste de Mann-Whitney e da regressão logística múltipla. Adotou-se o nível de significância estatística de 95%. Resultado: As prevalências de pensamentos, planejamento e tentativas de suicídio ao longa da vida foram respectivamente 196 (27,3%), 64 (8,9%) e 26 (3,6%). Nos 30 dias que antecederam a pesquisa, 36 (5%) pensaram seriamente em pôr fim à própria vida, e 11 (1,5%) planejaram concretamente colocar fim a própria vida. Bullying, presença de transtorno mental, procura de assistência em saúde mental na universidade, uso de calmante sem prescrição médica, baixo nível socioeconômico, morar sozinho, religião (ateus, agnósticos e espiritualistas) e grau de religiosidade são os fatores que, conjuntamente, melhor explicam a chance de comportamento suicida. Conclusão: Alunos de Medicina apresentam prevalências importantes de comportamento suicida.

Abstract: Introduction: Physicians and medical students constitute groups at risk for suicide and suicidal behavior. Suicidal behaviors encompass phenomena ranging from thoughts, planning, and finally death by suicide. Little is known about suicidal behavior among Brazilian medical students. Objective: The aim of this study was to assess the prevalence of suicidal ideation, planning and suicide attempt in a sample of undergraduate medical students in Brazil, as well as to identify the sociodemographic, student life aspects and health factors most often associated with suicidal behavior. Method: A total of 722 medical students at Unicamp, during 2017 and 2018, voluntarily and anonymously answered a broad questionnaire, including sociodemographic data, aspects of academic life and suicidal behavior. A statistical analysis was performed using the chi-square test, Mann-Whitney test, and multivariate logistic regression. A statistical significance level of 95% was adopted. Results: The lifetime prevalence rates of suicidal thoughts, planning and attempts were respectively 196 (27.3%), 64 (8.9%), and 26 (3.6%). In the 30 days prior to the survey, 36 (5%) seriously thought about ending their own lives, and 11 (1.5%) concretely planned to end their own lives. Bullying, presence of mental disorder, seeking mental health care at the university, use of sedatives without a prescription, low socioeconomic level, living alone, religion (atheists, agnostics and spiritualists) and degree of religiousness are the factors that, together, best explain the chance of suicidal behavior. Conclusion: Medical students show important prevalence rates of suicidal behavior.

RESUMO

Abstract: Introduction: Studies methylphenidate (MPH) has been used by medical students to increase their mental activity and improve the performance required during undergraduate school, generating concern regarding the risks to their physical and mental health. This scenario indicates the need for specifically aimed measures in medical schools. Objective: To review the literature about the use of MPH without medical indication amongst medical students. Method: A thorough review of the literature published in English, Spanish, and Portuguese, between 2013 and 2019, based on data made available by Pubmed and Scielo, utilizing keywords in the three above languages, along the four stages of the selection process. Results and Discussion: Altogether, 224 articles were found, of which 25 were selected after reading, dealing with the use of MPH or 'cognition enhancer' by undergraduate medical students without a doctor's prescription. The research indicated significant variability in the frequency of consumption, related to the investigated pattern of use, use with or without indication, before or after entering University and country where the study was carried out. The most frequent justification for the use without medical indication was to attain improvement in academic performance. A lack of research with a fair appraisal of the cognition, behavioral and psychic risks involved, among them addiction and the approach of the topic in medical schools, was noted. Conclusion: The high rates of usage of MPH by medical students aiming at cognitive enhancement strengthens the importance of preventative actions in medical schools. The strategies must consider information concerning the risks of use (of MPH) without medical indication; non-pharmacological interventions for performance improvement; sleep hygiene measures organization for adequate study activities; broad discussions about ethical aspects and curricular structure.

Resumo: Introdução: Estudos mostram que o metilfenidato (MPH) tem sido utilizado por estudantes de medicina para aumentar sua atividade mental e melhorar o desempenho exigido durante a graduação, gerando preocupações quanto aos riscos à sua saúde física e mental. Esse cenário indica a necessidade de medidas especificamente direcionadas nas escolas médicas. Objetivo: Revisar a literatura sobre o uso de MPH sem indicação médica entre estudantes de medicina. Método: Revisão minuciosa da literatura publicada em inglês, espanhol e português, entre 2013 e 2019, com base em dados disponibilizados pelo PUBMED e SCIELO, utilizando palavras-chave nos três idiomas acima, ao longo das quatro etapas do processo de seleção. Resultados e Discussão: Ao todo, foram encontrados 224 artigos, dos quais 25 foram selecionados após leitura, tratando do uso de MPH ou 'potencializador da cognição' por graduandos de medicina sem prescrição médica. A pesquisa indicou variabilidade significativa na frequência de consumo, relacionada ao padrão de uso investigado, uso com ou sem indicação, antes ou após a entrada na Universidade e país onde o estudo foi realizado. A justificativa mais frequente para o uso sem indicação médica foi a de obter melhora no desempenho acadêmico. Notou-se a carência de pesquisas com uma avaliação adequada dos riscos cognitivos, comportamentais e psíquicos envolvidos, entre eles o risco de adição e a abordagem do tópico nas escolas médicas. Conclusão: As altas taxas de uso do MPH por estudantes de medicina visando o aprimoramento cognitivo reforça a importância de ações preventivas nas escolas médicas. As estratégias devem considerar informações sobre os riscos do uso (do MPH) sem indicação médica; intervenções não farmacológicas para melhoria do desempenho cognitivo; medidas de higiene do sono; organização para atividades de estudo adequadas; amplas discussões sobre aspectos éticos e estrutura curricular.

RESUMO

This study investigated the psychometric properties of the Autism Mental Status Examination (AMSE) in a Brazilian sample of children and adolescents with autism spectrum disorder (ASD). A sample of 260 children and adolescents, comprising 56 (21.5%) females and 204 (78.5%) males, was assessed. The participants were submitted to both the childhood autism rating scale (CARS-BR) and the AMSE. The CARS-BR was used to estimate ASD severity and the cutoff point on the AMSE. Spearman's correlation test was employed to determine the correlation between the AMSE and CARS-BR scales. The cutoff values were calculated using the ROC (receiver operating characteristic) curve, identifying the sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV). The homogeneity of the items of the AMSE was determined using Cronbach´s alpha. The AMSE exhibited good internal consistency (0.74), sensitivity (0.91) and specificity (0.98); and high correlation with the CARS-BR (ρ = 0.91, p < 0.01). Preliminary results showed that the AMSE is a tool with good psychometric properties for ASD screening.

RESUMO

OBJECTIVE: To understand the process of resilience (social support and resources of the family environment) and the chance of mental health problems in children and adolescents (9-16 years) who have been victims of domestic violence, assisted in specialized services (Group 1 - G1) and in school services without reports of domestic violence (Group 2 - G2). METHODS: Various semi-structured instruments were applied to the pairs (guardian and child or adolescent): the Strengths and Difficulties Questionnaire (SDQ); the Resiliency Scales for Children and Adolescents (RSCA), including Scale I (SI - sense of control), Scale II (SII - relationship skills) and Scale III (SIII - emotional reactivity); the Social Support Appraisals; the Home Environment Resources Scale and a questionnaire created by the authors to characterize the population. RESULTS: There was no difference in the prevalence of resilience between G1 and G2. Children and adolescents of both groups had a higher chance of low resilience in the absence of perception of social support from the teacher (SI; SIII) and other people in the community (SI; SII). Girls had higher chance of low resilience (SIII). The establishment of routine or rules in the lives of the children and adolescents facilitated the development of resilience (SIII). In G1, the prevalence of mental health problems was 65% for the self-application version of the SDQ for children and adolescents (SDQ/CA) and 54% for the version answered by the guardians (SDQ/G). In G2, it was 33% for SDQ/CA and 37.9% for SDQ/G. Domestic violence against children and adolescents was a risk factor for the development of mental disorders (SDQ/G). Subjects with low resilience (SI) had a higher chance of developing mental health problems (SDQ/CA). Despite originating from the same regions, the groups had socioeconomic differences, which showed no relationship with resilience. CONCLUSIONS: The quality and perception of social support and resources present in the home environment may have facilitated the development of resilience in the studied children and adolescents. Violence may have increased the chance of mental health problems, domestic violence being an aggravating factor. There is need for research on aspects that predict resilience and investment in intervention strategies for this population, as a way to promote mental health.

RESUMO OBJETIVO: Compreender o processo de resiliência (suporte social e recursos do ambiente familiar) e a chance de problemas de saúde mental em crianças e adolescentes (9-16 anos) vítimas de violência doméstica acompanhados em serviços especializados (Grupo 1 - G1) e em escolares sem relatos de situações de violência doméstica (Grupo 2 - G2). MÉTODOS: Diversos instrumentos semiestruturados foram aplicados às díades (responsável e criança ou adolescente): Strengths and Difficulties Questionnaire (SDQ); Resiliency Scales for Children and Adolescents (RSCA), incluindo a Escala I (EI - sentido do controle), a Escala II (EII - capacidade de relacionamento) e a Escala III (EIII - reatividade emocional); Social Support Appraisals; Inventário de Recursos no Ambiente Familiar e um questionário elaborado pelos autores para caracterizar a população. RESULTADOS: Não houve diferença na prevalência de resiliência entre G1 e G2. As crianças e adolescentes de ambos os grupos tiveram maior chance de baixa resiliência na ausência de percepção do suporte social do professor (EI; EIII) e de outras pessoas da comunidade (EI; EII). Meninas apresentaram maior chance de baixa resiliência (EIII). O estabelecimento de rotina ou regras na vida das crianças e adolescentes facilitou o desenvolvimento da resiliência (EIII). No G1 a prevalência de problemas de saúde mental foi de 65% pela versão de autoaplicação do SDQ para crianças e adolescentes (SDQ/CA) e de 54% pela versão respondida pelos responsáveis (SDQ/R). No G2 foi de 33% pelo SDQ/CA e de 37,9% pelo SDQ/R. A violência doméstica infanto-juvenil foi fator de risco para o desenvolvimento de transtornos mentais (SDQ/R). Os sujeitos com baixa resiliência (EI) apresentaram maior chance de problemas de saúde mental (SDQ/CA). Embora provenientes das mesmas regiões, os grupos apresentaram diferenças socioeconômicas, as quais não apresentaram relação com a resiliência. CONCLUSÕES: A qualidade e percepção do suporte social e de recursos presentes no ambiente familiar podem ter facilitado o desenvolvimento da resiliência nas crianças e adolescentes estudados. A violência pode ter aumentado a chance de problemas de saúde mental, sendo a violência doméstica um agravante. Há necessidade de pesquisas sobre os aspectos preditores de resiliência e de investimento em estratégias de intervenção para esta população, como forma de promover a saúde mental.

RESUMO

BACKGROUND: Dopamine is involved in several cerebral physiological processes, and single nucleotide polymorphisms (SNP) in the dopamine D2 receptor gene (DRD2) have been associated with numerous neurological and mental disorders, including those involving alterations in cognitive and emotional processes. METHODS: The aim of this study was to evaluate the association between the SNPs c.957C > T (rs6277) and c.-585A > G (rs1799978) in the DRD2 gene and behavioral characteristics of children and adolescents based on an inventory of the Child Behavior Checklist (CBCL). Children and adolescents between 8 and 20 years old who were clinically followed-up were genotyped for the SNPs c.957C > T and c.-585A > G, and related to data of the CBCL/6-18 scale assessment performed with the help of caregivers. The chi-squared test was used to assess the differences in the frequencies of the C and T alleles in the polymorphism c.957C > T and of the A and G alleles in the polymorphism c.-585A > G with respect to the grouped CBCL scores at a significance level of 5%. Multiple logistic regression models were performed, to control whether sex and/or ethnicity could influence the results. RESULTS: Eighty-five patients were assessed overall, and the presence of the T allele (C/T and T/T) of DRD2 c.957C > T polymorphism was found to be significantly associated with the occurrence of defiant and oppositional problems and with attention and hyperactivity problems. There were no associations detected with polymorphism DRD2 c.-585A > G polymorphism. Both SNPs were in Hardy-Weinberg-equilibrium. CONCLUSIONS: Although the findings of this study are preliminary, due to its small number of participants, the presence of T allele (C/T, T/T) in c.957C > T SNP was associated with difficulty in impulse control, self-control of emotions, and conduct adjustment, which can contribute to improving the identification of mental and behavioral phenotypes associated with gene expression.
