Educational interventions in childhood obesity: a systematic review with meta-analysis of randomized clinical trials.

OBJECTIVE: To assess the effectiveness of educational interventions including behavioral modification, nutrition and physical activity to prevent or treat childhood obesity through a systematic review and meta-analysis of randomized trials. METHOD: A search of databases (PubMed, EMBASE and Cochrane CENTRAL) and references of published studies (from inception until May 2012) was conducted. Eligible studies were randomized trials enrolling children 6 to 12 years old and assessing the impact of educational interventions during 6 months or longer on waist circumference, body mass index (BMI), blood pressure and lipid profile to prevent or treat childhood obesity. Calculations were performed using a random effects method and pooled-effect estimates were obtained using the final values. RESULTS: Of 22.852 articles retrieved, 26 trials (23.617 participants) were included. There were no differences in outcomes assessed in prevention studies. However, in treatment studies, educational interventions were associated with a significant reduction in waist circumference [-3.21 cm (95%CI -6.34, -0.07)], BMI [-0.86 kg/m(2) (95%CI -1.59, -0.14)] and diastolic blood pressure [-3.68 mmHg (95%CI -5.48, -1.88)]. CONCLUSIONS: Educational interventions are effective in treatment, but not prevention, of childhood obesity and its consequences.

Genetic Syndromes Associated with Congenital Cardiac Defects and Ophthalmologic Changes - Systematization for Diagnosis in the Clinical Practice.

BACKGROUND: Numerous genetic syndromes associated with heart disease and ocular manifestations have been described. However, a compilation and a summarization of these syndromes for better consultation and comparison have not been performed yet. OBJECTIVE: The objective of this work is to systematize available evidence in the literature on different syndromes that may cause congenital heart diseases associated with ocular changes, focusing on the types of anatomical and functional changes. METHOD: A systematic search was performed on Medline electronic databases (PubMed, Embase, Cochrane, Lilacs) of articles published until January 2016. Eligibility criteria were case reports or review articles that evaluated the association of ophthalmic and cardiac abnormalities in genetic syndrome patients younger than 18 years. RESULTS: The most frequent genetic syndromes were: Down Syndrome, Velo-cardio-facial / DiGeorge Syndrome, Charge Syndrome and Noonan Syndrome. The most associated cardiac malformations with ocular findings were interatrial communication (77.4%), interventricular communication (51.6%), patent ductus arteriosus (35.4%), pulmonary artery stenosis (25.8%) and tetralogy of Fallot (22.5%). CONCLUSION: Due to their clinical variability, congenital cardiac malformations may progress asymptomatically to heart defects associated with high morbidity and mortality. For this reason, the identification of extra-cardiac characteristics that may somehow contribute to the diagnosis of the disease or reveal its severity is of great relevance.

Resumo Fundamento: O número de síndromes genéticas descritas que apresentam alguma forma de cardiopatia e manifestações oculares associadas é grande. Contudo, estas síndromes ainda não foram reunidas e sintetizadas para melhor consulta e comparação. Objetivo: O objetivo deste trabalho é sistematizar a literatura, avaliando evidências disponíveis sobre síndromes que cursam com cardiopatia congênita associada a alterações oculares, salientando os tipos de alterações anatômicas e funcionais descritas. Métodos: Dois pesquisadores independentes fizeram uma busca sistemática utilizando as bases eletrônicas Medline (PubMed, Embase, Cochrane, Lilacs), de trabalhos publicados até o mês de janeiro de 2016. Os critérios de elegibilidade utilizados pelos autores incluíram somente artigos publicados sob a forma de relatos de caso ou revisão, que abordassem a associação de alterações oftalmológicas e cardiológicas em pacientes menores de 18 anos e que apresentassem alguma síndrome genética. Resultados: As síndromes genéticas mais frequentes foram: Síndrome de Down, Síndrome Velo-cardio-facial / DiGeorge, Síndrome de Charge e Síndrome de Noonan. Entre as malformações cardíacas, a comunicação interatrial (77,4%), a comunicação interventricular (51.6%), a persistência do canal arterial (35,4%), estenose da artéria pulmonar (25,8%) e a tetralogia de Fallot (22,5%) foram as mais associadas com achados oculares. Conclusão: Devido à sua variedade clínica, as malformações cardíacas congênitas revelam defeitos que evoluem de maneira assintomática até aqueles que provocam grande morbimortalidade. Dessa forma, encontrar características extra-cardíacas que, de alguma maneira, possam auxiliar no diagnóstico da doença ou revelar a gravidade dessa enfermidade tornam-se de grande relevância.
