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 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.

Objective: To compare the distress level among Brazilian healthcare professionals during the coronavirus disease 2019 (COVID-19) pandemic and estimate risks by sex, age, and occupation. Methods: In a longitudinal cohort design, a nationally distributed online survey was used to collect data from 10,490 active healthcare professionals who worked during the pandemic. Participants were mostly female, aged 18 to 82 years; 13 different health professions and all states of Brazil were represented. Results: The most frequent professions were psychology, dentistry, and nursing. The Brief Symptom Inventory (BSI) score suggested an increased distress perception among health professionals. Females showed poorer mental health than males, but the absolute rise in Global Severity Index (GSI) score was larger in males than in females. Younger adults reported more symptoms of psychological distress than older adults. The most impacted age group was between 30-39 years. Nurse technicians presented the highest risk of distress. Conclusion: Health professionals are essential to overcoming the pandemic; thus, their mental health status should be monitored, and features associated with increased distress should be identified. Our findings suggest distress risk should be stratified by occupation, age, and sex. Health professionals showed an increased distress perception. Women, individuals between the ages of 30 and 39, nursing personnel, and physicians were more likely to report distress compared with other health professionals.

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.

Abstract Introduction The existence of a general factor related to psychiatric symptoms is supported by studies using a variety of methods in both clinical and non-clinical samples. Objectives This study aims to evaluate the replicability of the internal structure of the Brief Symptom Inventory in a large Brazilian sample. Methods Participants were 6,427 Brazilian subjects (81% female). Mean age was 42.1 years (standard deviation [SD] = 13.6, Min = 13, Max = 80). All participants completed the online version of the Brief Symptom Inventory. This scale presents a general score (GSI) and nine specific clusters of symptoms (depression, anxiety, phobic anxiety, interpersonal sensibility, psychoticism, paranoid ideation, obsessive-compulsive behavior, hostility, and somatization symptoms). Results Confirmatory factor analysis was performed to assess the factor structure of the BSI. The results showed that the best-fitting model was a bifactor solution and the general factor was the main dimension explaining most of the reliable variability in the data. Conclusion The findings suggest that the BSI’s internal structure was replicated in a non-clinical sample and that the general factor is the most reliable score. However, it is necessary to better understand the meaning of the general factor scores in a non-clinical sample to increase interpretability of scores.

RESUMO CONTEXTO: O exame padrão ouro para rastreamento de câncer colorretal é a colonoscopia. Apesar de ser o exame de escolha, a colonoscopia perde um número não desprezível de lesões, principalmente no cólon proximal. Com a intenção de reduzir a perda de lesões, novas técnicas são estudadas, dentre elas, a retroflexão em cólon direito e a segunda visão frontal direta. OBJETIVO: Avaliar a segurança da retrovisão no cólon proximal (ceco e cólon ascendente), o seu impacto na detecção de lesões em cólon proximal e sua superioridade sobre a dupla visão frontal direta usando taxa de detecção de adenoma e taxa de adenoma perdido. MÉTODOS: Foram avaliados 393 pacientes de forma prospectiva que procuraram o Hospital Mater Dei para realizar colonoscopia entre março e julho de 2017. Desses, 372 foram incluídos baseados nos critérios de exclusão: menores de 18 anos, preparos intestinais inadequados (escala de Boston <7), com antecedente de colectomia, doença inflamatória intestinal ou síndromes polipoides. Primeiramente um endoscopista realizou a inserção do colonoscópio até o ceco e examinou o ceco e o cólon ascendente em visão frontal por duas vezes. Na terceira reinserção até o ceco era realizada a retroflexão e inspeção da mucosa do ceco até a flexura hepática em busca de pólipos perdidos à visão frontal. Todas lesões encontradas foram ressecadas e enviadas para análise histológica. RESULTADOS: Em 334 (89,8%) pacientes a retroflexão foi realizada com sucesso, 65,8% dos insucessos foram atribuídos a alças no aparelho que impediram a manobra. A visão direta identificou 175 pólipos no cólon proximal em 102 pessoas. A retroflexão detectou 26 pólipos perdidos pela visão direta em 24 (6,5%) pessoas, com uma taxa de perda de 12,9% no exame apenas em visão frontal. Dos 26 pólipos encontrados em retrovisão, 21 (80,76%) eram adenomas, um deles com displasia de alto grau. Onze pacientes tinham pólipos vistos apenas em retroflexão. A realização da retrovisão aumentou a taxa de detecção de pólipo de 27,41% para 31,72% e a taxa de detecção e adenomas de 21,77% para 25%. A taxa de adenoma perdido pela dupla visão direta foi de 12,8%. Se a retrovisão não fosse realizada, um pólipo a cada 13,91 colonoscopias seria perdido (NNT=13,91). Não houve nenhum evento adverso. CONCLUSÃO: A técnica de retroflexão em cólon proximal mostrou-se segura, rápida e factível na maioria dos casos. Ela aumentou a taxa de detecção de adenomas e mostrou-se soberana neste estudo com benfeitorias além da dupla visão direta.

ABSTRACT BACKGROUND: The gold standard test for colorectal cancer screening the colonoscopy. Although this is the test of choice, colonoscopy misses a significant number of lesions, mainly in the proximal colon. With the purpose of reducing the number of lesions missed, new techniques have been studied, amongst them, retroflexed view in the right side of the colon and the second direct forward view. OBJECTIVE: Assessing the safety of the retroview in the proximal colon (cecum and ascending colon), its impact on the detection of lesions in the proximal colon and its advantage over the double right forward view using adenoma detection rate and adenoma miss rate. METHODS: Three hundred and ninety-three patients who came to Hospital Mater Dei to undergo colonoscopy from March to July 2017, prospectively. Out of these, 372 were included in the study based on the following exclusion criteria: being under 18 years of age, inadequate bowel preparations (Boston scale <7), history of colectomy, inflammatory bowel disease or polypoid diseases. First, an endoscopist inserted the colonoscope into the cecum and examine the cecum and the ascending colon with a forward view twice. In the third insertion into the cecum, retroflexed view was performed, cecal mucosa was examined until the hepatic flexure in search of polyps missed on forward view. All lesions found were resected and sent for histological analysis. RESULTS: In 334 (89.8%) patients, retroflexed view was performed successfully, 65.8% of failures were attributed to the loops of the device which prevented the maneuver. The direct view identified 175 polyps in the proximal colon in 102 people. Retroflexed view detected 26 polyps missed by the direct view in 24 (6.5%) people, with a missing rate of 12.9% in the test with only the forward view. Out of the 26 polyps found in retroview, 21 (80.76%) were adenomas, one of them with a high-grade dysplasia. Eleven patients had polyps seen only in retroflexed view. Retroview has increased the polyp detection rate from 27.41% to 31.72% and the adenoma detection rate from 21.77% to 25%. The adenoma miss rate by the double direct view was 12.8%. Without the retroview, one polyp in every 13.91 colonoscopies would be missed (number needed to treat - NNT=13.91). There was no adverse event. CONCLUSION: The retroflexed view technique in the proximal colon was shown to be safe, fast and feasible in most cases. It increased the adenoma detection rate and was shown to be advantageous in this study wit benefit beyond the double direct view.

RESUMO CONTEXTO: Hepatite autoimune (HAI) é uma doença hepática inflamatória crônica, rara, associada à perda da tolerância imunológica aos auto-antígenos. A susceptibilidade à HAI é parcialmente determinada pela presença de genes relacionados ao antígeno leucocitário humano (HLA), principalmente variantes alélicas do DRB1. OBJETIVO: O objetivo deste estudo foi investigar a frequência de polimorfismos no gene HLA-DRB1 em crianças e adolescentes com HAI tipo 1 e HAI tipo 1 associada à colangite autoimune, em comparação com indivíduos saudáveis pareados por sexo e idade (grupo controle). MÉTODOS: Este é um estudo transversal de 25 pacientes pediátricos com diagnóstico de HAI tipo 1 e 18 com HAI associada à colangite autoimune. Cinquenta e sete indivíduos saudáveis foram incluídos como controles. Os polimorfismos do gene HLA-DRB1 foram avaliados por PCR e incluíram HLA-DRB1*03, HLA-DRB1*04, HLA-DRB1*07 e HLA-DRB1*13. RESULTADOS: Nossos resultados mostraram que a presença do alelo HLA-DRB1*13 aumentou a chance de colangite autoimune (OR=3,96; IC 1,07 a 14,61; P=0,04). O HLA-DRB1*04 e o HLA-DRB1*07 não apresentam associação com a HAI e colangite autoimune no grupo de pacientes mais jovens. CONCLUSÃO: Este trabalho demonstra uma associação dos principais polimorfismos no gene HLA-DRB1 à HAI com ou sem colangite na população brasileira.

ABSTRACT BACKGROUND: Autoimmune hepatitis (AIH) is a rare chronic inflammatory liver disease associated with a loss of immunological tolerance to self-antigens. Susceptibility to AIH is partially determined by the presence of genes related to human leukocyte antigen (HLA), mainly allelic variants of DRB1. OBJECTIVE: The purpose of this study was to investigate the frequencies of the polymorphisms in HLA-DRB1 gene in children and adolescents with type 1 AIH and type 1 AIH overlap syndrome with autoimmune cholangitis (overlap syndrome, OS) in comparison to healthy sex and age-matched individuals (control group). METHODS: This is a cross-sectional study of 25 pediatric patients diagnosed with type 1 AIH and 18 with OS. Fifty-seven healthy individuals were included as controls. The polymorphisms of the HLA-DRB1 gene were evaluated by PCR and included HLA-DRB1*03, HLA-DRB1*04, HLA-DRB1*07, and HLA-DRB1*13. RESULTS: Our results showed that the presence of the allele HLA-DRB1*13 increased the chance of autoimmune cholangitis (OR=3.96, CI 1.07 to 14.61, P=0.04). The HLA-DRB1*04 and HLA- DRB1*07 have no association with the AIH and autoimmune cholangitis in a young sample. CONCLUSION: This work demonstrates an association of the main polymorphisms in the HLA-DRB1 gene to AIH with or without cholangitis in a Brazilian sample.

RESUMO Objetivo Derivar valores de referência em adultos brancos para a difusão do monóxido de carbono (DCO) em uma amostra de diferentes locais do Brasil por um mesmo modelo de equipamento (Sensormedics) e comparar os resultados com os derivados pelas equações de Crapo, Miller e Neder, e da proposta pelo Global Lung Initiative (GLI). Métodos Os testes foram realizados de acordo com as normas sugeridas pela ATS/ERS, em 2005, em seis cidades brasileiras, em 120 voluntários adultos de cada sexo, não fumantes, sem anemia referida e sem doenças pulmonares ou cardíacas. Os previstos foram derivados por regressões lineares e as diferenças entre os valores previstos por alguns autores e os observados no estudo atual foram calculadas. Resultados Nos homens, a idade variou de 25 a 88 anos e a estatura, de 156 a 189 cm. Nas mulheres, a idade variou de 21 a 92 anos e a estatura, de 140 a 176 cm. A DCO se correlacionou de maneira significativa positivamente com a estatura e negativamente com a idade. Os valores previstos pelas equações de Crapo, Neder e Miller foram maiores em comparação aos obtidos pelo estudo atual (p<0,01) em ambos os sexos. Nos homens, os valores não diferiram quando comparados aos calculados pelo GLI (p=0,29); nas mulheres, os valores derivados pelo GLI foram levemente maiores: 0,99 mL/min/mmHg (p<0,01). Conclusões Novos valores previstos para a DCO foram derivados em uma amostra de adultos brancos no Brasil. Os valores previstos são semelhantes aos compilados pelas equações GLI e diferem de equações propostas anteriormente.

ABSTRACT Objective To derive reference values from white race adults, for DCO in a sample from different sites in Brazil, through the same equipment model (Sensormedics), and compare the results with the derivatives from Crapo, Miller, Neder equations and from the Global Lung Initiative (GLI) proposal. Methods The tests were performed according to the norms suggested by ATS/ERS in 2005 in six Brazilian cities, with 120 adult volunteers of each gender, non-smokers, without referred anemia and without lung or cardio diseases. The expected values were derived from linear regressions and the differences between the values forecasted by some authors and the ones observed in the current study were calculated. Results Among men, the age varied between 25 and 88 years old, and the height varied between 140 and 176 cm. DCO was correlated significantly and positively with the height and negatively with the age. The values forecasted by Crapo, Neder, and Miller equations were higher in comparison with the ones obtained by the current study (p<0.01) in both genders. Among men, the values did not differ when compared to the ones calculated by GLI (p=0.29); among women, the values derived by GLI were slightly higher: 0.99 ml/min/mmHg (p<0.01). Conclusion new values forecasted for DCO were derived in a sample of white adults in Brazil. The forecasted values are similar to the ones complied by GLI equations and differ from the previously proposed equations.

Resumo Introdução: No Transtorno do Déficit de Atenção com Hiperatividade, a identificação de prejuízos funcionais no contexto domiciliar é um elemento importante para o diagnóstico. Objetivo: Avaliar o conhecimento científico acerca da participação doméstica de crianças e adolescentes com déficit de atenção com hiperatividade e implicações para a prática clínica. Método: Revisão sistemática com as palavras-chave/descritores, “attention deficit disorder with hyperactivity”, “ADHD”, “household chores” e “household task” no PubMed e Scopus. Os critérios de inclusão adotados foram: artigos originais, em inglês, amostra composta por crianças e adolescentes com o diagnóstico de TDAH, com idade entre 6 e 17 anos e artigos disponíveis em suas versões completas. Resultados: A busca resultou em 43 estudos, sendo apenas quatro incluídos. A partir da análise dos artigos foi possível constatar que crianças com déficit de atenção com hiperatividade desempenham tarefas de modo semelhante ao de crianças com desenvolvimento típico, todavia crianças com TDAH recebem mais assistência pelos cuidadores quando comparadas a seus pares. A idade, sexo, irmão mais velho e a importância atribuída pelos pais parecem estar associados ao aumento no desempenho das tarefas, enquanto os sintomas de oposição, ter o diagnóstico de TDAH e o nível de estresse dos pais, ao aumento da assistência pelos cuidadores. Conclusão: São poucos os estudos envolvendo crianças com déficit de atenção com hiperatividade, e não é possível a generalização dos achados. Investigações futuras sobre outros fatores do ambiente domiciliar são necessárias para ampliar o conhecimento sobre a participação dessa população e nortear intervenções para a prática clínica.

Abstract Introduction: In the Attention-Deficit/Hyperactivity Disorder (ADHD), the identification of functional impairments in home context is an important feature for the diagnosis. Objective: To evaluate the scientific knowledge regarding household participation of children with attention deficit with hyperactivity and implications for clinical practice. Method: A systematic review was performed using the keywords: “attention deficit disorder with hyperactivity”, “ADHD”, “household chores” and “household task” at PUBMED and SCOPUS. The inclusion criteria adopted were: original articles, in English, studied population composed of children and adolescents with attention deficit hyperactivity disorder, 6 to 17 years old, and articles available in their complete versions. Results: The search resulted in 43 articles, and only four studies were included. From the analysis of the articles, it was verified that children with attention deficit hyperactivity disorder perform tasks similar to children with typical development. However, children with ADHD receive more assistance of caregivers than their peers. Age, gender, presence of older sibling, and the importance attributed by parents seem to be associated with increased task performance, while oppositional symptoms, diagnosis of attention deficit hyperactivity disorder, and parental stress level seem to be associated with increased care from caregivers. Conclusion: Few studies evaluated household chores participation of children with attention deficit hyperactivity disorder and the findings cannot be generalized. Future investigations about other factors of home environment still need to improve the knowledge about the participation of this population and then to guide interventions in clinical practice.

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.

ABSTRACT Objects To compare insulin resistance (IR) and metabolic aspects of patients with neurofibromatosis type 1 (NF1) and individuals without the disease. Subjects and methods Forty patients with NF1 were matched by sex, age, and body mass index (BMI) to 40 controls from the community. Blood samples were collected for biochemical assessment. Homeostasis model assessment adiponectin (HOMA-AD), Homeostasis model assessment insulin resistance (HOMA-IR), and adiponectin/leptin ratio (ALR) were used to identify IR. Results The median HOMA-IR values were similar between the groups. However, the HOMA-AD value was significantly lower and the ALR significantly higher in the NF1 group. Fasting blood glucose (FBG), leptin, and visfatin levels of patients with NF1 were significantly lower, although adiponectin levels were significantly higher than those in the controls. Fasting insulin and blood glucose levels 2 hours after administration of 75 g of dextrose, glycated hemoglobin, and resistin showed no significant differences between groups. The HOMA-AD correlated with BMI, FBG, blood glucose levels 2 hours after administration of 75 g of dextrose, fasting insulin, glycated hemoglobin, adiponectin, leptin, visfatin, ALR, and HOMA-IR. The ALR correlated with BMI leptin, visfatin, and adiponectin. Conclusions Lower levels of FBG, leptin, visfatin, and HOMA-AD, and higher adiponectin levels and ALR may be related to increased insulin sensitivity and lower occurrence of type 2 diabetes mellitus in patients with NF1

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.

RESUMO Objetivo: Buscar sistematicamente evidências fundamentadas e de qualidade sobre o processamento sensorial em crianças nascidas pré-termo no período da infância. Fontes de dados: A busca da literatura disponível sobre o tema foi realizada nas bases de dados eletrônicas Sistema Online de Busca e Análise de Literatura Médica (Medline)/PubMed, Literatura Latino-Americana e do Caribe em Ciências da Saúde (Lilacs)/Biblioteca Virtual em Saúde (BVS), Índice Bibliográfico Español de Ciencias de la Salud (IBECS)/BVS, Scopus e Web of Science. Foram incluídos estudos indexados, originais, quantitativos e disponíveis na íntegra em meio digital, publicados em português, inglês ou espanhol, entre 2005 e 2015, envolvendo crianças entre zero e 9 anos de idade. Síntese dos dados: A busca identificou 581 artigos, e oito foram incluídos conforme critérios de elegibilidade. Destes, seis estudos (75%) encontraram alta frequência de processamento sensorial alterado em crianças pré-termo. A associação entre processamento sensorial e desfechos de desenvolvimento foi observada em três estudos (37,5%). Verificou-se associação entre processamento sensorial e características neonatais em cinco estudos (62,5%). Os resultados de processamento sensorial frequentemente se associam a idade gestacional, sexo masculino e lesões da substância branca. Conclusões: Análise da literatura atual sugere que prematuridade tem impacto negativo no processamento sensorial. Idade gestacional, sexo masculino e lesões de substância branca aparecem como fatores de risco para alterações de processamento sensorial em crianças nascidas pré-termo. O prejuízo na capacidade de receber informações sensoriais, de integrar e de adaptar-se a elas parece interferir negativamente no desenvolvimento motor, cognitivo e de linguagem dessas crianças. Destaca-se a viabilidade da identificação das alterações de processamento sensorial nos primeiros anos de vida, favorecendo o encaminhamento precoce para intervenções clínicas.

ABSTRACT Objective: To conduct a systematic search for grounded and quality evidence of sensory processing in preterm infants during childhood. Data source: The search of the available literature on the theme was held in the following electronic databases: Medical Literature Analysis and Retrieval System Online (Medline)/PubMed, Latin American and Caribbean Literature in Health Sciences (Lilacs)/Virtual Library in Health (BVS), Índice Bibliográfico Español de Ciencias de la Salud (IBECS)/BVS, Scopus, and Web of Science. We included only original indexed studies with a quantitative approach, which were available in full text on digital media, published in Portuguese, English, or Spanish between 2005 and 2015, involving children aged 0-9years. Data synthesis: 581 articles were identified and eight were included. Six studies (75%) found high frequency of dysfunction in sensory processing in preterm infants. The association of sensory processing with developmental outcomes was observed in three studies (37.5%). The association of sensory processing with neonatal characteristics was observed in five studies (62.5%), and the sensory processing results are often associated with gestational age, male gender, and white matter lesions. Conclusions: The current literature suggests that preterm birth affects the sensory processing, negatively. Gestational age, male gender, and white matter lesions appear as risk factors for sensoryprocessing disorders in preterm infants. The impairment in the ability to receivesensory inputs, to integrateand to adapt to them seems to have a negative effect on motor, cognitive, and language development of these children. We highlight the feasibility of identifying sensory processing disorders early in life, favoring early clinical interventions.

RESUMO O objetivo foi avaliar os efeitos da estimulação transcraniana por corrente contínua (ETCC) sobre o córtex motor primário (M1) nas assimetrias de desempenho manual em uma tarefa de destreza manual. A amostra foi composta por 28 voluntários, destros, do sexo masculino e sem comprometimento neurológico. A tarefa (Grooved Pegboard) consistiu em encaixar 25 pinos em 25 receptáculos, o mais rápido possível. A tarefa foi executada no pré-teste com ambas as mãos para definição do nível de assimetria manual. Uma semana após o pré-teste foi aplicado a ETCC ou placebo, em seguida os sujeitos foram avaliados no pós-teste. Os resultados revelaram que os efeitos da ETCC no M1 não foram capazes de diminuir as assimetrias manuais em uma tarefa de destreza manual em sujeitos destros. Entretanto, somente o grupo ETCC melhorou o desempenho do pré-teste para o pós-teste (p<0,05) em ambas as mãos. A estimulação do M1 direito pode ter gerado benefícios no M1 contralateral.

ABSTRACT The aim of this study was to evaluate the effect of transcranial direct-current stimulation (tDCS) on the primary motor cortex (M1) in the manual performance asymmetries in a manual dexterity tasks. The sample consisted of 28 volunteers, right-handed, men and without neurological impairment. The task (Grooved Pegboard) consisted of inserting 25 pins in 25 receptacles, as soon as possible. The task was executed in the pretest with both hands to define the level of manual asymmetry. tDCS or Sham were applied a week after the pretest, then the subjects were evaluated in the post-test. The results revealed that the effects of tDCS in M1 did not reduce asymmetries in a manual dexterity task. However, only the tDCS group improved the performance from pretest to the posttest (p <0.05) in both hands. Stimulation of the right M1 may have generated benefits in the contralateral M1.
