ABSTRACT Objective: To analyze the cognitive development of preterm infants at six and 12 months of corrected age and the associations with perinatal and socioeconomic factors. Methods: Cognitive development of 40 infants (20 preterm and 20 full-term) at six and 12 months of age was evaluated using the Bayley-III scale. Correlations between cognitive outcome and associated factors were assessed using Spearman correlation. Stepwise multiple linear regression analysis with covariance was applied to identify changes on cognitive score between six and 12 months. Results: Bayley-III cognitive score in preterm group was significantly lower than in full-term group at both six and 12 months of age. Birth weight correlated with cognitive performance at six months and head circumference at birth at 12 months, in full-terms infants. The occurrence of necrotizing enterocolitis was inversely associated with cognitive score in preterms at 12 months. An increase in cognitive score was observed between six and 12 months in both groups, but the gain was more pronounced in preterms. Conclusions: These findings suggest some cognitive recovery capacity in the first year despite the restrictions imposed by premature birth and emphasize the importance of early interventions in this population.

RESUMO Objetivo: Avaliar o desenvolvimento cognitivo de crianças pré-termo aos seis e 12 meses de idade corrigida e as associações com fatores perinatais e socioeconômicos. Métodos: O desenvolvimento cognitivo de 40 crianças (20 pré-termo e 20 a termo) foi avaliado aos seis e 12 meses de idade, utilizando a escala Bayley-III. Correlações entre resultados cognitivos e fatores associados foram avaliadas pelo teste de correlação de Spearman. A análise de regressão linear múltipla stepwise com covariância foi aplicada para identificar mudanças na pontuação cognitiva entre seis e 12 meses. Resultados: O escore cognitivo no grupo pré-termo foi significativamente menor que no grupo a termo aos seis e 12 meses. O peso ao nascer foi diretamente associado com o desempenho cognitivo aos seis meses e perímetro cefálico ao nascimento aos 12 meses, nas crianças a termo. A ocorrência de enterocolite necrosante foi inversamente associada ao desempenho cognitivo em pré-termos, aos 12 meses. Verificou-se aumento na pontuação cognitiva entre seis e 12 meses nos dois grupos, porém mais pronunciado no pré-termo. Conclusões: O estudo sugere que crianças pré-termo apresentam alguma capacidade de recuperação cognitiva no primeiro ano, apesar das restrições impostas pelo nascimento prematuro, e enfatizam a importância de acompanhamento dessa população desde os primeiros meses de vida.

ABSTRACT Objective To investigate the prevalence of internet gaming disorder (IGD) symptoms in a sample of Brazilian adults, and its association with personality, psychiatric symptoms and psychosocial measures. Methods We evaluated 219 adults online recruited using questionnaires and psychometric scales. We evaluated the behavior and pattern of internet games using the Game Addiction Scale (GAS). We tested the association of the previous measures with the GAS scores by spearman correlations and multiple regression analysis. Results Of our sample, 74% played games online. We found correlations between IGD symptoms and most symptoms of mental disorders, with small or moderate effect sizes, as well as correlations with the personality traits of agreeableness (r = -0.272; p < 0.001), conscientiousness (r = - 0.314; p < 0.001), and neuroticism (r = 0.299; p < 0.001). Additionally, we found a negative association with psychosocial outcomes such as quality of life (r = -0.339; p < 0.001) and life satisfaction (r = - 0.202; p < 0.003). The multivariate model included the personality traits of conscientiousness and agreeableness and symptoms of dissociation and somatization as predictors. The prevalence of IGD was 9% in those who played online games. Conclusion IGD is correlated with different areas of the individual’s life, such as personality, quality of life, and several common symptoms of mental disorders. The prevalence can be considered high among players (9%). Conscientiousness, agreeability, somatic symptoms, and dissociative symptoms were associated with the symptoms of IGD.

RESUMO Objetivo Investigar a prevalência de sintomas do transtorno do jogo pela internet (TJI) em uma amostra de adultos brasileiros e sua associação com personalidade, sintomas psiquiátricos e medidas psicossociais. Métodos Avaliamos 219 adultos recrutados on-line por meio de questionários e escalas psicométricas. Avaliamos o comportamento e o padrão dos jogos na internet usando a Game Addiction Scale (GAS). Testamos a associação das medidas anteriores com as pontuações na GAS por meio de correlações de Spearman e análise de regressão múltipla. Resultados De nossa amostra, 74% jogavam jogos on-line. Encontramos correlações entre sintomas do TJI e a maioria dos sintomas de transtornos mentais, com tamanhos de efeito pequenos ou moderados, bem como correlações com os traços de personalidade de amabilidade (r = -0,272; p < 0,001), conscienciosidade (r = - 0,314; p < 0,001) e neuroticismo (r = 0,299; p < 0,001). Além disso, encontramos uma associação negativa com resultados psicossociais, como qualidade de vida (r = -0,339; p < 0,001) e satisfação com a vida (r = - 0,202; p < 0,003). O modelo multivariado incluiu os traços de personalidade de conscienciosidade e amabilidade e sintomas de dissociação e somatização como preditores. A prevalência de TJI foi de 9% entre os que jogavam jogos on-line. Conclusão O TJI está correlacionado com diferentes áreas da vida do indivíduo, como personalidade, qualidade de vida e vários sintomas comuns de transtornos mentais. A prevalência pode ser considerada alta entre os jogadores (9%). Conscienciosidade, amabilidade, sintomas somáticos e sintomas dissociativos estavam associados aos sintomas do TJI.

Abstract Objective: To translate and validate the version for children and adolescents of the UPPS-P scale into Brazilian Portuguese. Method: After a five-step translation process, the final draft was submitted to a panel of 12 different specialties experts. Subsequently, the application of the scale was applied concomitantly with the "Swanson, Nolan, and Pelham Scale - Version IV" (SNAP-IV) and the "Child and Adolescent Behavior Inventory" (CABI) scale to analyze the correlation between them. Content Validity Index (CVI) and reliability were estimated by calculating internal consistency and analyzing its test-retest stability. Results: The items whose CVI was lower than 80% underwent a detailed analysis to verify the reason for the bad evaluation. Five items (3, 7, 11, 22 and 35) scored below 80% and were reassessed. There was high internal consistency in all parameters: Lack of premeditation (McDonald's omega = 0.806; Cronbach's alpha = 0.801), Negative Urgency (McDonald's omega = 0.838; Cronbach's alpha = 0.836), Sensation seeking (McDonald's omega = 0.826; Cronbach's alpha = 0.810), Lack of Perseverance (McDonald's omega = 0.800; Cronbach's alpha = 0.799) and Positive Urgency (McDonald's omega = 0.936; Cronbach's alpha = 0.934). A strong correlation was observed between UPPS-P features and impulsivity in behavioral assessments. Conclusions: The Brazilian Portuguese version of the UPPS-P scale is a good instrument to assess impulsivity in children and adolescents.

ABSTRACT Purpose The purpose of this study was to investigate the relationship between parenting styles and hearing skills in children with hearing loss who use cochlear implants. Methods This is an observational analytical study. The participants were the children’s main caregivers divided into a study group (N=50) and a control group (N=28). The children’s ages were between 3 and 7 years old. Subjects in the study group provided a past medical history (PMH), and completed the Parenting Styles and Dimensions Questionnaire (PSDQ) and the Infant-Toddler Meaningful Auditory Integration Scale (IT-MAIS) or the Meaningful Auditory Integration Scale (MAIS). Subjects in the control group also provided a PMH and completed the PSDQ. The Mann Whitney test, the Spearman coefficient, and the Kruskal-Wallis test were used for data analysis, utilizing the JASP 0.8 and SPSS 23 softwares. Results Results showed that The authoritarian parenting style and punishment dimension revealed a statistical significance, with higher scores for children with altered auditory development. Conclusion It was concluded that the practice of authoritarian parenting style with punitive dimensions and physical coercion were related to altered hearing development. Regulation dimension presented a significant correlation with hearing development. The outcome suggested the importance of psychotherapeutic strategies for caregivers who are responsible for children with hearing loss.

RESUMO Objetivo O objetivo deste estudo foi investigar a relação entre estilos parentais e habilidades auditivas em crianças usuárias de implante coclear. Métodos Este é um estudo analítico observacional. Os participantes foram os cuidadores principais das crianças divididos em grupo estudo (N=50) e grupo controle (N=28). As idades das crianças estavam entre 3 e 7 anos. Os indivíduos do grupo estudo forneceram uma história médica pregressa (HMP) e preencheram o Questionário de Estilos e Dimensões Parentais (QEDP) e a Escala de Integração Auditiva Significativa Infantil-Toddler (IT-MAIS) ou a Escala de Integração Auditiva Significativa (MAIS). Os sujeitos do grupo controle também forneceram um PMH e preencheram o QEDP. O teste de Mann Whitney, o coeficiente de Spearman e o teste de Kruskal-Wallis foram utilizados para análise dos dados, utilizando-se os softwares JASP 0.8 e SPSS 23. Resultados Os grupos estudo e controle não apresentam diferenças significativas em relação aos estilos parentais (p<0,05). A dimensão estilo parental autoritário e punição revelou significância estatística, com escores mais elevados para crianças com desenvolvimento auditivo alterado. Conclusão No presente estudo foi possível verificar que a prática do estilo parental autoritário com dimensões punitivas e coerção física esteve relacionada ao desenvolvimento auditivo alterado em crianças usuárias de implante coclear.

RESUMO. O transtorno do espectro do autismo (TEA) é caracterizado por dificuldades na interação social e comportamentos/interesses inflexíveis. Com o intuito de quantificar os traços de TEA em adultos com inteligência preservada, foi desenvolvido o quociente do espectro do autismo (QA), um instrumento de autorrelato muito utilizado e recomendado. Objetivos: Nosso objetivo foi apresentar uma análise descritiva do QA em uma amostra de adultos brasileiros com desenvolvimento neurotípico (n=385) e investigar o desempenho da escala em uma subamostra clínica (n=33). Métodos: Foram recrutados 1.024 participantes, que responderam ao Self-Reporting Questionnaire-20 (SRQ-20), ao QA e a questões sobre o seu histórico psiquiátrico. Em seguida, selecionamos 385 participantes sem qualquer diagnóstico psiquiátrico para descrever a distribuição dos traços de TEA. Para investigar o desempenho do QA, avaliamos 33 adultos com TEA e 19 adultos com desenvolvimento neurotípico da amostra total (n=1024). Resultados: As características do TEA apresentaram distribuição normal na amostra, com alta consistência interna. Do total de 91 homens, os voluntários com 32 pontos (ponto de corte clínico) ou mais pontuaram acima de 93% da amostra de controle. De 294 mulheres, aquelas que obtiveram pontuação clínica na escala pontuaram acima de 97%. Na subamostra clínica (n=33), o valor preditivo positivo do QA foi de 0,84 e o valor preditivo negativo foi de 0,7. Conclusões: A população estudada apresenta um perfil diferente comparada à população do estudo original, no que se refere à escala QA. Os traços de TEA foram normalmente distribuídos na amostra neurotípica, e a escala parece ter um desempenho satisfatório para predizer autismo. Estudos futuros são necessários para adequar o uso da escala na população brasileira.

ABSTRACT. Autism spectrum disorder (ASD) is characterized by difficulties in social interaction and inflexible behaviors/interests. To quantify ASD traits in adults with preserved intelligence, the Autism Spectrum Quotient (AQ) was developed, which is a self-report instrument and one of the most used and recommended tools. Objectives: We aimed to present a descriptive analysis of the AQ in a sample of Brazilian adults with neurotypical development (n=385) and investigate how the scale performs in a clinical subsample (n=33). Methods: We recruited 1,024 participants. They answered the Self-Reporting Questionnaire-20 (SRQ-20), AQ, and about their psychiatric record. Then, we selected 385 participants without any psychiatric diagnosis to describe the distribution of the ASD traits. To investigate the AQ performance, we evaluated 33 adults with ASD and 19 adults with neurotypical development from the total sample (n=1,024). Results: ASD traits were normally distributed in the population, with high internal consistency. Of a total of 91 men, volunteers with 32 points (clinical cutoff point) or more scored higher than 93% of the control sample. Of a total of 294 women, those who got a clinical score on the scale scored higher than 97%. In the clinical subsample (n=33), the positive predictive value (PPV) of the AQ was 0.84, and the negative predictive value (NPV) was 0.7. Conclusions: The study population has a different profile compared to the original study regarding the AQ scale. ASD traits were normally distributed in the neurotypical sample, and the scale seems to have a satisfactory performance to predict ASD. Future studies are required to adequate the use of the scale in the Brazilian population.

RESUMO Objetivo: Investigar as propriedades psicométricas da versão curta ou MTA da escala Swanson, Nolan e Pelham, versão IV (SNAP-IV), que mede os sintomas do transtorno de déficit de atenção/hiperatividade e transtorno desafiador de oposição. Métodos: Os participantes incluíram 765 pais de crianças de 4 a 16 anos (641 crianças sem transtorno de déficit de atenção/hiperatividade e 124 com transtorno de déficit de atenção/hiperatividade) de Belo Horizonte, Brasil, que relataram características sociodemográficas e responderam o SNAP-IV. Os pais da amostra clínica também foram submetidos à entrevista com K-SADS-PL. Resultados: A idade foi significativamente associada aos problemas de hiperatividade-impulsividade no SNAP-IV (r = −0,14), mas não à desatenção ou aos transtornos desafiadores de oposição. O sexo foi uma influência significativa na gravidade do transtorno de déficit de atenção/hiperatividade e transtorno desafiador de oposição (todos os p < 0,001), os meninos apresentaram escores mais altos na amostra completa, mas não no grupo de transtorno de déficit de atenção/hiperatividade. A análise fatorial exploratória e confirmatória apoia uma estrutura de três fatores da escala SNAP-IV. Foram encontradas correlações moderadas a fortes entre as medidas dos instrumentos SNAP-IV e K-SADS-PL. Todas as escalas do SNAP-IV mostraram coeficientes de consistência interna muito altos (todos acima de 0,91). Os escores de desatenção do SNAP-IV foram os mais preditivos do diagnóstico de transtorno de déficit de atenção/hiperatividade (AUC - área sob a curva ROC: 0,877 para o método de classificação da média e o método da soma bruta e 0,874 para o método de presença ou ausência de sintomas). Conclusão: A avaliação do SNAP-IV pelos pais apresentou boas propriedades psicométricas em uma escola brasileira e amostra clínica.

ABSTRACT Objective: To investigate the psychometric properties of the short or multimodal treatment study version of the Swanson, Nolan, and Pelham, Version IV (SNAP-IV) scale, which measures attention-deficit/hyperactivity disorder and oppositional defiant disorder symptoms. Methods: Participants were 765 parents of children from 4 to 16 years old (641 non-attention-deficit/hyperactivity disorder and 124 attention-deficit/hyperactivity disorder children) from Belo Horizonte, Brazil, who reported sociodemographic characteristics and answered the SNAP-IV. Parents of the clinical sample also underwent the K-SADS-PL interview. Results: Age was significantly associated with SNAP-IV hyperactivity-impulsivity problems (r = −0.14), but not with inattention or oppositional defiant disorder. Sex was a significant influence on attention-deficit/hyperactivity disorder and oppositional defiant disorder severity (all p < 0.001), with boys showing higher scores in the full sample, but not within the attention-deficit/hyperactivity disorder group. Exploratory and confirmatory factor analysis supports a three-factor structure of the SNAP-IV scale. Moderate-to-strong correlations were found between SNAP-IV and K-SADS-PL measures. All SNAP-IV scales showed very high internal consistency coefficients (all above 0.91). SNAP-IV inattention scores were the most predictive of attention-deficit/hyperactivity disorder diagnosis (AUC: 0.877 for the averaging rating method and the raw sum method, and 0.874 for the symptom presence/absence method). Conclusion: The parent SNAP-IV showed good psychometric properties in a Brazilian school and clinical sample.

RESUMO Objetivo Falhas cognitivas são erros cometidos no dia a dia como perda de compromissos, falta de palavras ao conversar, dificuldades de memorizar o que é lido, erros de orientação, entre outros. Sintomas psiquiátricos internalizantes e externalizantes podem contribuir para a ocorrência de falhas cognitivas. O presente estudo objetiva avaliar como sintomas internalizantes e externalizantes contribuem para a ocorrência de falhas cognitivas no dia a dia. Métodos Foram avaliados 366 voluntários utilizando o Questionário de Falhas Cognitivas (CFQ) e as escalas Self-Reporting Questionnaire-20 (SRQ-20), como medida de sintomas internalizantes, e Adult Self-Report Scale (ASRS-18), como medida de sintomas externalizantes. Os participantes foram classificados com base nos pontos de corte da SRQ-20 e ASRS-18 para a criação de quatro grupos: hígido, internalizante, externalizante e misto. Comparamos os grupos por meio de ANOVA e testamos a associação das variáveis estudadas por meio de correlações. Resultados Todas as escalas apresentaram correlações fortes entre si (r > 0,500, p < 0,001). A comparação dos grupos sugere que participantes com escores clínicos de sintomas internalizantes e externalizantes apresentam mais falhas quando comparados ao grupo hígido (d = 0,86 e d = 1,00), mas não apresentam diferenças entre si (d = 0,21). Participantes do grupo misto apresentaram mais falhas que o grupo hígido (d = 2,01), internalizante (d = 1,31) e externalizante (d = 1,05). Conclusão Tanto sintomas internalizantes quanto externalizantes contribuem para a ocorrência de falhas cognitivas no dia a dia. Observamos ainda um efeito aditivo de ambos os sintomas.

ABSTRACT Objective Cognitive failures are errors made in everyday life such as forgetting appointments, lack of words when talking, difficulties to memorize what is read, errors of orientation, among others. Internalizing and externalizing psychiatric symptoms may contribute to the occurrence of cognitive failures. The present study aims to evaluate how internalizing and externalizing symptoms contribute to the occurrence of everyday cognitive failures. Methods We evaluated 366 volunteers using the Cognitive Failure Questionnaire (CFQ), the Self-Reporting Questionnaire-20 (SRQ-20) as a measure of internalizing symptoms and the Adult Self-Report Scale (ASRS-18) as a measure of externalizing symptoms. We classified the participants based on the SRQ-20 and ASRS-18 cut-off scores to create four groups: controls, internalizing, externalizing, and mixed. We compared the groups by means of ANOVA and tested its associations with correlations. Results All scales showed strong correlations between each other (r > 0.500, p < 0.001). The comparison of the groups suggests that participants with clinical scores of internalizing and externalizing symptoms have more failures when compared to the control group (d = 0.86 and d = 1.00), but they do not present differences between themselves (d = 0.21). Participants of the mixed group presented more failures than the control group (d = 2.01), and the internalizing (d = 1.31) and externalizing (d = 1.05) groups. Conclusion Both internalizing and externalizing symptoms contribute to the occurrence of day-to-day cognitive failures. We also observed an additive effect of both symptoms.

Abstract Background: Children and adolescents are considered a population at risk for developing posttraumatic stress disorder (PTSD) after a traumatic event. The Children's Revised Impact Scale (CRIES-8) is a self-report scale with 8 items that investigates avoidance and intrusion behaviors related to posttraumatic stress symptoms. Objective: The study consisted of translation and transcultural adaptation of CRIES-8 to Brazilian Portuguese and evaluation of its psychometric properties. Methods: A sample of 235 Brazilian children and adolescents exposed to natural hazards (drought or flood) and non-exposed children participated in the study. The methodological procedure for translation and cultural adaptation were in accordance with the principles described by ISPOR Task Force for Translation and Cultural Adaptation. We also evaluated test reliability and validity based on test content, the relations to other variables, and internal structure. Results: The procedures lead to a final Portuguese version proofread and cultural-adapted. Empirical evidence supports CRIES-8's division in two latent constructs (Intrusion and Avoidance), as well convergence correlations with other measures of child mental health and high reliability. Discussion: A Brazilian-Portuguese version of CRIES-8 is an important tool for a better screening of PTSD among youth who face traumatic events, being a potential informative instrument to identify children at risk.

RESUMO O presente estudo avalia a associação entre velocidade de processamento, funções executivas e memória em uma amostra de diferentes faixas etárias. O estudo testa a hipótese de que a velocidade de processamento, as funções executivas e a memória apresentam associação mais forte na infância e na velhice. Avaliamos 571 participantes, com idade entre seis e 92 anos, divididos em quatro grupos etários: crianças/adolescentes, adultos jovens, adultos de meia-idade e idosos. Análises de correlação sugerem que a variância compartilhada entre velocidade de processamento e memória é forte na infância e fraca nas demais idades. Já as funções executivas apresentaram associação forte com a memória tanto na infância quanto na velhice, quando comparadas aos estágios intermediários. Concluímos que os efeitos da atenção sobre a memória variam em função da idade do participante. Essas funções podem ser mecanismos compensatórios para a memória ao longo do desenvolvimento.

ABSTRACT The present study evaluated the association between episodic memory, executive function and processing speed in a sample with different age ranges. We tested the hypothesis that processing speed, executive function and memory are more strongly associated during childhood and old age. We evaluated 571 participants, aged six to 92 years, divided into four age groups: children/adolescents, young adults, middle-aged adults and older adults. Correlation analyses suggested that the shared variance between the processing speed and memory is strong in childhood but weak across other age ranges. Executive function, however, had a stronger association both in childhood and in old age, when compared with the intermediate stages. We conclude that the effects of processing speed and executive function on memory are not stable across human development. These functions may be compensatory mechanisms for memory functioning in childhood and old age.

Abstract Background Passionate love involves physiological, emotional, and cognitive features that greatly changes behavior. This phenomenon seems universal or near universal. Even other animal species choose partners. An intense state of passionate love is associated with activity in dopamine pathways of the brain ‘reward system’, and recently has been regarded as a ‘natural addiction’. Instruments or tools to evaluate romantic love during childhood is still scarce. Objective To perform the translation and cultural adaptation of the Juvenile Love Scale (JLS) for use in the Brazilian context targeted for adolescents between 14 and 18 years old. Methods The translation and cultural adaptation of JLS followed international recommendations, and its content validity was analyzed by a panel of experts in different areas of knowledge. Results The final version of the JLS for use in the Brazilian context showed high content validity (> 90%). Discussion To our knowledge, this is the first scale for measuring romantic or passionate love in adolescents adapted to the Brazilian context. This instrument is a significant contribution to the study of the dimensions of love, as well as to understand the impact of love on the psychiatric phenomena that pervade life in this stage of development.

Abstract Background There is growing interest in the role of religion in psychiatric disorders. Impulsivity is a psychological trait associated with acting without thinking, with a decision process favoring short-term outcomes without further consideration of its consequences, and is a risk factor for the development of mental disorders. Objective In this study, the objective was to analyze the role of religiosity as a possible moderator between the association of impulsivity and internalizing psychiatric symptoms. Methods The hypothesis was assessed in a cross-sectional study enrolling 366 adults evaluated using the abbreviated version of the Barratt Impulsiveness Scale-11, the Self Reporting Questionnaire-20, and the Duke Religion Index. Results Internalizing symptoms were significantly influenced by an interaction between religiosity and impulsivity. Religiosity acted as a protective factor against internalizing symptoms only for participants with high impulsivity. Discussion The results suggest a moderation role of religiosity in the association of impulsivity with internalizing symptoms.

Abstract AIMSThe purpose of this study was to investigate how depressive symptoms mediate different motor control requirements in elderlies and to assess the concurring effects fomented by the interaction between aging and depressive symptoms, providing indirect measures of brain functionality. METHODS Sixty-eight elderlies were paired in terms of age and gender and were equally distributed into depressed and nondepressed groups, according to their score on the Beck Depression Questionnaire. The participants performed the Grooved Pegboard Test placing and withdrawing pegs while execution time and error rate were measured. RESULTS This investigation revealed that depressive symptoms exert a broad effect upon motor control, although that the symptom intensity, as well as the interaction between aging and depression intensity, were exclusively correlated with withdrawal task, suggesting that there is a greater effect upon motor acts with higher frontal lobe requirements. CONCLUSION The discrimination of motor control aspects provides a valuable contribution for the understanding of the underlying neurophysiology of the interaction between aging and depression as it represents an indirect measure of cerebral dysfunction. Further, these findings may still have clinical implications, as they can promote more rational approaches to the elaboration of preventive measures that help maintain the functional capability of depressed elderlies.

Resumo A disfunção do trato urinário inferior (DTUI) afeta cerca de 2 a 25% da população pediátrica e se associa à presença de transtornos emocionais e de comportamento. O objetivo dessa revisão bibliográfica foi selecionar estudos que enfoquem os transtornos mentais em crianças e adolescentes com DTUI. A prevalência destes transtornos é elevada - variando de cerca de 20 a 40% nas crianças com sintomas da DTUI e comorbidades. A presença de sintomas emocionais e comportamentais impacta no tratamento da disfunção, na autoestima dos pacientes e também nos cuidadores. Apesar da associação entre transtornos mentais/comportamentais e DTUI estar bem documentada na literatura, a investigação de sintomas psiquiátricos na prática clínica ainda é pouco realizada e deve ser estimulada.

Abstract Lower urinary tract dysfunction (LUTD) affects about 2-25% of the pediatric population and is associated with the presence of emotional and behavioral disorders. The purpose of this literature review was to identify studies focusing on mental disorders in children and adolescents with LUTD. The prevalence of these disorders is high - ranging from about 20 to 40% - in children with symptoms of LUTD and comorbidities. The presence of emotional and behavioral symptoms impact in the treatment of the dysfunction, self-esteem of patients and caregivers. Despite the association between mental/behavioral disorders and LUTD be well documented in the literature, the investigation of psychiatric symptoms in clinical practice is still not common and should be stimulated.

Resumo Objetivo A obesidade é uma doença crônica sustentada por fatores ambientais e genéticos. Estudos epidemiológicos documentaram que maior ingestão de energia e um estilo de vida sedentário, bem como a contribuição genética, são forças por trás da epidemia de obesidade. O conhecimento sobre a interação entre os componentes genéticos e ambientais pode facilitar a escolha das medidas mais efetivas e específicas para a prevenção da obesidade. O objetivo deste estudo foi avaliar a relação entre os genes associado à massa de gordura e à obesidade (FTO), homólogo 1 do oncogene viral v-akt de timoma murino (AKT1) e de ligação AKT1 (AKTIP) e a obesidade infantil e a resistência à insulina. Métodos Estudo de caso-controle no qual os polimorfismos de nucleotídeo simples (SNPs) nos genes FTO (rs99396096), AKT1 e AKTIP foram genotipados em grupos de controle e de crianças obesas/acima do peso. Foram recrutadas 195 crianças obesas/acima do peso e 153 indivíduos controle. Resultados Como esperado, os indivíduos do grupo obeso/acima do peso apresentaram maior índice de massa corporal, maior glicemia de jejum, índice do modelo de avaliação de homeostase (HOMA-IR), colesterol total, lipoproteína de baixa densidade e triglicerídeos. Contudo, não encontramos diferenças significativas no genótipo de polimorfismos gênicos ou nas frequências alélicas. Conclusão Nossos resultados sugerem que os polimorfismos AKT1, FTO e AKTIP não estavam associados à obesidade/sobrepeso em crianças brasileiras. São necessários estudos futuros sobre a genética da obesidade em crianças brasileiras e suas interações ambientais.

Abstract Objective: Obesity is a chronic disease caused by both environmental and genetic factors. Epidemiological studies have documented that increased energy intake and sedentary lifestyle, as well as a genetic contribution, are forces behind the obesity epidemic. Knowledge about the interaction between genetic and environmental components can facilitate the choice of the most effective and specific measures for the prevention of obesity. The aim of this study was to assess the association between the FTO, AKT1, and AKTIP genes and childhood obesity and insulin resistance. Methods: This was a case-control study in which SNPs in the FTO (rs99396096), AKT1, and AKTIP genes were genotyped in groups of controls and obese/overweight children. The study included 195 obese/overweight children and 153 control subjects. Results: As expected, the obese/overweight group subjects had higher body mass index, higher fasting glucose, HOMA-IR index, total cholesterol, low-density lipoprotein, and triglycerides. However, no significant differences were observed in genes polymorphisms genotype or allele frequencies. Conclusion: The present results suggest that AKT1, FTO, and AKTIP polymorphisms were not associated with obesity/overweight in Brazilians children. Future studies on the genetics of obesity in Brazilian children and their environment interactions are needed.

RESUMO Objetivo O presente estudo analisou a confiabilidade do Teste dos Cinco Dígitos (FDT), um instrumento de avaliação dos processos atencionais baseado no paradigma Stroop. O teste usa números e quantidades para avaliação do efeito de interferência atencional. Métodos Avaliamos 49 adultos brasileiros por meio do FDT. Os participantes realizaram o teste em dois momentos, com aproximadamente duas semanas de intervalo. A confiabilidade do teste foi estimada pela consistência interna (método das metades) e pela avaliação da estabilidade teste-reteste (coeficiente de correlação intraclasse e teste de Wilcoxon para amostras repetidas). Resultados O tempo de resposta médio dos participantes apresentou discreta melhora nas etapas mais simples do teste e mais acentuada nas etapas mais complexas. A consistência interna do teste foi superior a 0,9. A estabilidade teste-reteste variou em função da etapa do teste, e todas as correlações foram significativas (p < 0,01) e explicaram entre 60% e 90% da variância encontrada. Conclusão O FDT apresenta evidências robustas de confiabilidade na amostra avaliada. Esse foi o primeiro estudo brasileiro a avaliar essa propriedade pelo método de teste-reteste. Os resultados propiciam melhor aplicabilidade do FDT nos contextos de clínica e pesquisa.

ABSTRACT Objective This study examined the reliability test of the Five Digits (FDT), an assessment tool of attentional processes based on Stroop paradigm. The test uses numbers and quantities for the assessment of attentional interference effect. Methods We assessed 49 Brazilian adults through FDT. Participants performed the test on two occasions, about two weeks apart. The test reliability was estimated by internal consistency (split-half method) and the evaluation of test-retest stability (intraclass correlation coefficient and Wilcoxon test for repeated measures). Results The mean response time of the participants showed a slight improvement in the simpler test measures and more pronounced in the more complex ones. The internal consistency of the test was 0.9. The test-retest stability varied depending on the test stage, where all correlations were significant (p < 0.01) and explained between 60% and 90% of the explained variance. Conclusion FDT provides robust evidence of reliability of the sample investigated. This was the first Brazilian study to evaluate this property by test-retest method. The results provide a better applicability of FDT in clinical and research settings.
