ABSTRACT

Abstract Background: School interventions based on playful activities have been shown to be good strategies for increasing children's knowledge about health, which may impact healthy habits. Objective: To evaluate whether the school health education program entitled "Happy Life, Healthy Heart" increases health knowledge and causes a change in teachers' and students' lifestyles. Method: Cluster randomized clinical trial including elementary school students and teachers from public schools in the city of Frederico Westphalen, Brazil. The intervention consisted of the training of teachers on topics of health, followed by classes on topics related to cardiovascular health given by these teachers to the students. The students were evaluated for nutritional status and health knowledge using the CARDIOKIDS and DAFA questionnaires, and teachers were assessed for physical activity. The Student's t-test, the chi-square test and the two-way ANOVA test were used for comparisons between groups, and McNemar-Bowker for intra-group comparisons. P values of <0.05 were considered statistically significant. Results: A total of 473 children were included, 211 (44.6%) in the control group (CG) and 262 (55.4%) in the intervention group (IG), and 32 teachers (control = 14, intervention =18). There was no difference in health knowledge of the students after the intervention (CG 10.53 ± 0.11 vs. 11.19 ± 0.09 p = 0.061, IG 10.20 ± 0.12 vs. 11.09 ± 0, 09 p = 0.416), although 57.7% of the children of the IG reported having stopped eating pizza and drinking soft drinks (p <0.001), following the Brazilian Food Guide recommendations. Among teachers of the IG, an increase of 27.9% in physical activity level was observed. Conclusions: The "Happy life, healthy heart" program was able to change students' eating habits and increase physical activity in teachers.

ABSTRACT

Abstract Background: Long-term outcomes of patients with Fontan circulation are uncertain regarding the prevalence and role of risk factors (RFs) such as increased body mass index (BMI), arterial hypertension, and hypercholesterolemia. Objectives: To describe the prevalence of RFs in patients with univentricular heart, with variable follow-up times. Methods: This mixed cohort study was performed with 66 patients, who underwent blood count, fasting blood glucose, C-reactive protein (CRP), and lipid profile tests; systolic/diastolic blood pressure (SBP/DBP) measurements; and anthropometric and sociodemographic data collection. Cardiovascular RFs among first-degree relatives and physical activity habits were also assessed. Prevalence was described using proportions, with a 95% confidence interval. Continuous variables (height, weight, age, SBP, DBP) were described as means and standard deviations (m±SD). Associations between RFs were assessed using chi-squared or Fisher's exact tests. Spearman's correlation was used for analyzing CRP and the presence of 2 or more RFs. The Shapiro-Wilk test was used to check for data normality. Statistical significance considered p<0.05. Results: In our population, 19.7% were overweight, mean SBP was 89.44±37.4, and mean DBP was 60.0±26.08. The most prevalent diseases in the interviewees' families were systemic arterial hypertension (30.3%), obesity (16.7%), and 2 or more cardiovascular RFs among first-degree relatives (13.8%). We observed a trend towards significance between the presence of 2 familial RFs and overweight, as well as a risk profile for cardiovascular disease. There was an association between the BMI percentile, the presence of 2 or more RFs (p<0.05), and CRP (p<0.01). Conclusions: Overweight is common in patients with univentricular heart, being related to more than 2 cardiovascular RFs among first-degree relatives; physical inactivity and changes in lipid profiles are also frequent.

ABSTRACT

Abstract Background Obesity and overweight in childhood can increase the risk of developing cardiovascular disease throughout live. Objectives This study provides an update of a meta-analysis of randomized clinical trials (RCT) published in 2014, to assess the effects of physical activity interventions on preventing cardiovascular risk factors in childhood. Methods This update combines data from the previous search with new data obtained from June 2013 to June 2020. Searches were performed on PubMed, EMBASE and Cochrane CENTRAL. The RCTs enrolled used interventions with physical activity longer than six months in school children aged 6-12 years, and evaluated body mass index (BMI), systolic blood pressure (SBP), diastolic blood pressure (DBP), total cholesterol (TC), triglyceride (TG), and low-density lipoprotein (LDL) and high-density lipoprotein (HDL) levels. Data analysis was performed using a random-effects model and a P value <0.05 was considered statistically significant. Results A total of 28,603 articles were retrieved, and 17 RCTs (11,952 subjects) were included. Physical activity interventions were associated with reduction in SBP [−2.11mmHg (95%CI −3.67, −0.54), I243%], DBP [−2.08mmHg (95%CI −3.68, −0,49), I265%] and TG [-0.08mmol/L (95% CI -0.13, -0.03), I20%], and increase in TC [0.17mmol/L (95%CI 0.04, 0.30), I20%]. However, the interventions were not associated with reductions in BMI [−0.03 kg/m2 (95%CI −0.17, 0.10), I20%]. Conclusion This update confirms and reinforces the beneficial effects of physical activity intervention in reducing systolic and diastolic blood pressure and TG levels.

ABSTRACT

Abstract Background The impact of chronic diseases on the patient and the family ranges from minimal to severe distress. Family functioning has been often investigated as a psychosocial measure having an essential role for social adjustment in chronic diseases. Objectives To compare family functioning among families of adolescents with congenital heart disease (CHD) and healthy controls (H) in relation to cohesion, adaptability, and family risk. Method Cross-sectional exposed-control study with 2 groups of adolescents (12 -18 years). The exposed group included adolescents with congenital heart disease (CHD), from a specialized public health system hospital (SUS), and adolescents from 7 public schools, considered healthy, composed the control group. In the hospital, the data collection was individual, before the medical consultation. In schools, the collection took place in groups. Adolescents and parents responded to the FACES III scale. The following statistical tests were used: Pearson's chi-square, Fisher's test, T-test for independent samples, Poisson multivariate regression analysis with 95% reliability, significance established at 5% and a statistical power at 99% (ß = 0.01). Results A total of 161 (41.6%) adolescents with CHD and 226 (58.4%) healthy adolescents participated. There was greater family cohesion among adolescents with CHD, with a higher frequency of connected families, while among healthy adolescents, there are more families of the disengaged type. Regarding adaptability, a higher proportion of families of the chaotic type were found among healthy adolescents compared to adolescents with CHD. A higher frequency of high-risk families was identified among healthy adolescents (16.8%). Conclusion The families of the adolescents with CHD have a more balanced functioning and low risk when compared to the families of healthy adolescents; with greater cohesion between the members and greater adaptability. Congenital heart disease was not an independent factor for high-risk family. (Int J Cardiovasc Sci. 2020; [online].ahead print, PP.0-0).

ABSTRACT

Abstract Objective To translate the Leuven Knowledge Questionnaire for Congenital Heart Disease into Brazilian Portuguese and to validate its psychometric properties with parents and family caregivers of children with congenital heart disease. Method This was a six-step methodological study, including the translation, synthesis, back-translation, evaluation of the version translated by the committee of experts, pre-testing, and validation, for which two pilot tests were used including the think-aloud protocol. The content validity index and the frequency of socioeconomic data were calculated in a statistical programming environment. Results In content validation, the instrument showed good applicability among experts, with average content validity index of 0.8-1, while kappa agreement analysis was between 0.76 to 1; both results were considered adequate for validation. Conclusions The results suggest reliability among the evaluators, indicating the instrument's accuracy and the possibility of using it to assess the knowledge of parents and family caregivers about congenital heart disease.

ABSTRACT

ABSTRACT OBJECTIVE To evaluate the prevalence of reports of symptoms of COVID-19 among individuals with and without antibodies and identify those with greater capability to predict the presence of antibodies against SARS-CoV-2. METHODS The study uses data collected in phases 5 to 8 of Epicovid-19-RS. The presence of antibodies against SARS-CoV-2 was evaluated by a rapid test. The occurrence of cough, fever, palpitations, sore throat, difficulty breathing, changes in taste and smell, vomiting, diarrhea, body pain, shaking, and headache since March 2020 was also evaluated. Then, the capability to predict the evaluated symptoms concerning the presence of antibodies was calculated. RESULTS A total of 18,000 individuals were interviewed and 181 had antibodies against COVID-19 in phases 5 to 8. The proportion of asymptomatic individuals was 19.9% among participants with antibodies and 49.7% among those without antibodies. All symptoms were reported more frequently by individuals with antibodies. The division of the prevalence of symptoms among individuals with antibodies by the prevalence among individuals without antibodies showed the following prevalence ratios: for changes in smell or taste (9.1), fever (4.2), tremors (3.9), breathing difficulty (3.2) and cough (2.8 times). Anosmia and fever were the symptoms with a greater capability to predict the presence of antibodies. CONCLUSION The prevalence of symptoms was higher among individuals with antibodies against SARS-CoV-2. The proportion of asymptomatic individuals was low. Altered smell or taste and fever were the symptoms that most predict the presence of antibodies. These results can help to identify probable cases, contributing to the clinical diagnosis and screening of patients for testing and isolation guidance in positive cases, especially in scenarios of the scarcity of diagnostic COVID-19 tests.


RESUMO OBJETIVO Avaliar prevalência de relato de sintomas característicos de covid-19 entre indivíduos com e sem anticorpos e identificar aqueles com maior capacidade de predição da presença de anticorpos contra o SARS-CoV-2. MÉTODOS O presente estudo usa dados coletados nas fases de 5 a 8 do Epicovid-19-RS. A presença de anticorpos contra o SARS-CoV-2 foi avaliada por um teste rápido. Avaliou-se também a ocorrência dos sintomas tosse, febre, palpitações, dor de garganta, dificuldade para respirar, alterações no paladar e olfato, vômito, diarreia, dor no corpo, tremedeira e dor de cabeça, desde março de 2020. Então, calculou-se a capacidade de predição dos sintomas avaliados em relação a presença de anticorpos. RESULTADOS Nas fases de 5 a 8, 18 mil indivíduos foram entrevistados e 181 apresentaram anticorpos contra covid-19. A proporção de indivíduos assintomáticos foi de 19,9% entre participantes com anticorpos e 49,7% entre aqueles sem anticorpos. Todos os sintomas foram relatados com maior frequência por indivíduos com presença de anticorpos. A divisão da prevalência de sintomas entre indivíduos com anticorpos pela prevalência entre indivíduos sem anticorpos evidenciou as seguintes razões de prevalência: para alterações de olfato ou paladar (9,1), febre (4,2), tremedeira (3,9), dificuldade respiratória (3,2) e tosse (2,8 vezes). Anosmia e febre foram os sintomas com maior capacidade de predizer a presença de anticorpos. CONCLUSÃO A prevalência de sintomas foi maior entre indivíduos com anticorpos contra SARS-CoV-2. A proporção de indivíduos assintomáticos foi baixa. Alteração de olfato ou paladar e febre foram os sintomas que mais predizem a presença de anticorpos. Esses resultados podem auxiliar a identificação de casos prováveis, contribuindo para o diagnóstico clínico e triagem de pacientes para testagem e orientação de isolamento em casos positivos, especialmente em cenários de escassez de testes diagnósticos de covid-19.

ABSTRACT

Abstract Objective: The preparation of parents of children who should undergo cardiac surgery requires special treatment such as the explanations about the event. This study aims to compare the effects of standardized nursing guidelines with routine institutional orientation on the anxiety of parents of children undergoing cardiac surgery. Methods: Randomized clinical trial. The sample consisted of parents of children who underwent cardiac surgery from December 2010 to April 2011. Twenty-two parents were randomized to the intervention group (IG) and received the standard nursing guidelines and 22 participated in the control group (CG) and received the routine guidelines from the institution. Anxiety was assessed by the State-Trait Anxiety Inventory (STAI) applied in the preoperative period, between 12 and 20 hours before surgery and before receiving standard or institutional guidelines and 48 hours after surgery. The analysis of variance (ANOVA) for repeated measures was performed to evaluate the differences between the variations in STAI scores between the groups during the studied period. The level of significance was 0.05. Results: There were no significant differences in baseline anxiety scores between groups with regard to trait anxiety as well as state anxiety: STAI-trait (CG 42.6±4.9 vs. IG 41.4±6.0, P=0.48); STAI-state (CG 42.3±5.7 vs. IG 45.6±8.3, P=0.18). Likewise, the variation in score after 48 hours was similar between groups (STAI-trait P=0.77; STAI-state P=0.61). Conclusion: There were no significant differences in the parents' anxiety levels when comparing the two types of guidelines: the standard nursing and the institutional orientation.

ABSTRACT

Resumo Fundamento O conhecimento sobre a própria doença pode ser importante para o autocuidado em pacientes com vários problemas e abrange a informação sobre o diagnóstico até as implicações clínicas mais importantes. Objetivo Identificar o nível de conhecimento de crianças e adolescentes com cardiopatia congênita (CC) sobre a sua doença, e analisar a relação entre o nível de conhecimento e a prática de atividade física. Métodos Estudo transversal com 335 pacientes com CC, de 8 a 13 anos, acompanhados em um serviço de cardiologia pediátrica de referência no Sul do Brasil. Os pacientes foram entrevistados em relação ao seu conhecimento sobre a CC e foi realizada revisão dos prontuários para obtenção de detalhes sobre a cardiopatia e os procedimentos. Foi utilizado o nível de significância p < 0,05. Resultados Mais de 50% das crianças e adolescentes não sabiam referir o nome de sua doença ou explicá-la. Após OR ajustado (ORaj), mostraram potencial para respostas incorretas ou não saber sua doença os pacientes cianóticos em relação aos acianóticos (ORaj: 2,29; IC95%: 1,76-6,71; p=0,019); crianças com menor nível de escolaridade (ORaj: 2,20; IC95%: 1,81-5,86; p=0,025); e não praticantes de atividade física (ORaj: 1,88; IC95%: 1,09-3,45; p=0,011). Conclusão As crianças e adolescentes cianóticos, com menor nível de escolaridade e que não praticavam de atividade física apresentaram pouco conhecimento sobre a sua doença. Há necessidade do desenvolvimento de estratégias de intervenções educativas para aumento do conhecimento e mudança comportamental na promoção da atividade física, de acordo com a complexidade da CC. (Arq Bras Cardiol. 2020; 114(5):786-792)


Abstract Background Knowledge about the disease itself can be important for self-care in patients with several problems and comprehends information about the diagnosis up to the most important clinical implications. Objective To identify the level of knowledge of children and adolescents with congenital heart disease (CHD) about their illness, and to analyze the association between the level of knowledge and the practice of physical activity. Methods Cross-sectional study with 335 patients with CHD, aged 8 to 13 years, followed at a referral pediatric cardiology service in Southern Brazil. Patients were interviewed regarding their knowledge about CHD and a review of medical records was performed to obtain details on heart disease and procedures. A significance level p<0.05 was used. Results More than 50% of the children and adolescents did not know how to say the name of their disease or explain it. After adjusted OR (AOR), cyanotic patients in comparison to acyanotic ones (AOR: 2.29; 95%CI: 1.76-6.71; p = 0.019); children with lower level of schooling (AOR: 2.20; 95%CI: 1.81-5.86; p = 0.025); and those who did not practice physical activity (AOR: 1.88; 95%CI: 1.09-3.45; p = 0.011) showed potential for incorrect answers or did not know their disease. Conclusion Cyanotic children and adolescents, with a lower level of schooling and who did not practice physical activity, had little knowledge about their disease. It is necessary to develop educational intervention strategies to increase knowledge and change behavior in physical activity promotion, according to the CHD complexity.

ABSTRACT

Abstract The first case of COVID-19 was reported in China in December 2019, and, as the virus has spread worldwide, the World Health Organization declared it a pandemic. Estimates on the number of COVID-19 cases do not reflect it real magnitude as testing is limited. Population based data on the proportion of the population with antibodies is relevant for planning public health policies. We aim to assess the prevalence of SARS-CoV-2 antibodies, presence of signs and symptoms of COVID-19, and adherence to isolation measures. A random sample comprising 133 sentinel cities from all states of the country will be selected. Three serological surveys, three weeks apart, will be conducted. The most populous municipality in each intermediate region of the country, defined by the Brazilian Institute of Geography and Statistics, was chosen as sentinel city. In each city, 25 census tracts will be selected, and 10 households will be systematically sampled in each tract, totaling 33,250 participants. In each household, one inhabitant will be randomly selected to be interviewed and tested for antibodies against SARS-CoV-2, using WONDFO SARS-CoV-2 Antibody Test. By evaluating a representative sample of Brazilian sentinel sites, this study will provide essential information for the design of health policies.


Resumo O COVID-19 é causado pelo vírus SARS-CoV-2, sendo o primeiro caso relatado na China em dezembro de 2019. O vírus se espalhou pelo mundo, levando a Organização Mundial da Saúde a declarar uma pandemia. As estimativas do número de casos de COVID-19 não refletem sua magnitude real, pois os testes são limitados em muitos países. Dados populacionais sobre a proporção da população com anticorpos são relevantes para o planejamento de políticas públicas de saúde. Nosso objetivo é avaliar a prevalência de anticorpos SARS-CoV-2, a presença de sinais e de sintomas de COVID-19 e a adesão a medidas de isolamento. Uma amostra aleatória composta por 133 cidades sentinelas de todos os estados do país será selecionada. Serão realizados três levantamentos sorológicos, com três semanas de intervalo. Em cada cidade, serão selecionados 25 setores censitários e 10 famílias serão amostradas aleatoriamente em cada setor. Em cada domicílio, um habitante será selecionado aleatoriamente para ser entrevistado e testado para anticorpos contra SARS-CoV-2, usando o Teste de Anticorpo WONDFO SARS-CoV-2, que foi validado antes do trabalho de campo. Ao avaliar uma amostra representativa dos locais sentinela ao longo do tempo, este estudo fornecerá informações essenciais para o desenho de políticas de saúde.

ABSTRACT

Abstract Background: Stress is a state of threat to the balance of the organism, which can cause biological and psychological changes. In hypertensive patients, stress can interfere with blood pressure levels, influence on food choices and neglect of the diet. Objective: This study aims to describe the relationship between stress and dietary intake of hypertensive patients. Methods: A transversal study was carried out at the Arterial Hypertension Clinic of the Cardiology Institute of Rio Grande do Sul, Brazil. The participants were aged ≥ 18 years and hypertensive. Blood pressure, food consumption and anthropometric measurements were collected. The variables related to stress were evaluated by the Lipp's Stress Symptoms Inventory (LSSI) for adults. Significance level of 5% has been considered for all analyzed data. Results: The number of participants was 100. There was a higher prevalence of the female sex (67%), the mean age of the study population was 55.87 ± 12.55 years. Among the participants, 86% were classified in some of the stress phases, on which 57% were in the resistance phase. It was observed that there was no correlation between the presence of stress (as well as their actions), pressure levels and food consumption. The consumption of foods rich in lipids and individuals with a prevalence of psychological symptoms of stress displayed a significant association. Conclusions: Rich in fat dietary has been the first choice in patients with psychological symptoms of stress. Further studies regarding remodeled dietary intake and blood pressure levels in relation to the stress phases are suggested. These findings are important to contribute to the development of prevention and treatment strategies for cardiovascular diseases.


Resumo Fundamento: O estresse é um estado de ameaça ao equilíbrio do organismo, podendo causar alterações biológicas e psicológicas. No paciente hipertenso o estresse pode interferir nos níveis pressóricos e gerar influência nas escolhas alimentares e negligência da dieta. Objetivo: Este estudo tem como objetivo descrever a relação entre o estresse e consumo alimentar de pacientes hipertensos. Métodos: Estudo transversal, desenvolvido no Ambulatório de Hipertensão Arterial do Instituto de Cardiologia do Rio Grande do Sul. Participaram da pesquisa indivíduos hipertensos com idade > 18 anos. Foram coletados dados de pressão arterial, consumo alimentar e medidas antropométricas. As variáveis relacionadas ao estresse foram avaliadas pelo inventário de sintomas de stress para adultos de Lipp (ISSL). Em todas as análises foi considerando um nível de significância 5% (p < 0,05). Resultados: O número de participantes foi de 100. Houve maior prevalência no sexo feminino (67%), a idade média da população estudada foi 55,87 ± 12,55 anos. Dos participantes, 86% se classificaram em alguma das fases do estresse, sendo que destes, 57% estavam na fase de resistência. Observou-se que não houve correlação entre a presença de estresse (bem como suas fases), níveis pressóricos e consumo alimentar. O consumo de alimentos ricos em lipídios em hipertensos com sintomas de estresse apresentou significância estatística. Conclusão: Os alimentos ricos em gordura prevaleceram entre as escolhas alimentares nos pacientes com sintomas psicológicos de estresse. Sugere-se mais estudos em relação a alteração do consumo alimentar e níveis pressóricos em relação às fases do estresse.

ABSTRACT

ABSTRACT Objective: To evaluate the physical activity level and functional capacity of children and adolescents with congenital heart disease and to describe correlations between functionality, surgical and echocardiographic findings, metabolic and inflammatory profile and differences between acyanotic and cyanotic heart defects. Methods: A cross-sectional study including children and adolescents with congenital heart disease between six and 18 years old that were evaluated with the 6-minute walk test (6MWT) to assess functional capacity. The short version form of the International Physical Activity Questionnaire (IPAQ) was performed to evaluate physical activity levels. Also, echocardiography and blood collection, to evaluate the metabolic (blood glucose, lipids, insulin) and inflammatory markers (C-reactive protein), were assessed. Results: Twenty-five individuals were evaluated. Of them, 14 had acyanotic heart defects and 11 cyanotic heart defects. Mean age was 12.0±3.7 years, and 20 (80%) were male. IPAQ showed that six (24%) individuals were very active, eight (32%) were active, nine (36%) had irregular physical activity, and two (8%) were sedentary. The mean distance walked in the 6MWT, considering all studied individuals, was 464.7±100.4 m, which was 181.4±42.0 m less than the predicted (p=0.005). There was a positive correlation between Z score 6MWT and the number of surgical procedures (r=-0.455; p=0.022). Conclusions: Children and adolescents with congenital heart disease have low functional capacity, but they are not completely sedentary.


RESUMO Objetivo: Avaliar o nível de atividade física e a capacidade funcional de crianças e adolescentes com cardiopatia congênita, além de descrever correlações entre funcionalidade, achados cirúrgicos e ecocardiográficos, perfil metabólico e inflamatório e diferenças entre cardiopatias congênitas acianótica e cianótica. Métodos: Estudo transversal com crianças e adolescentes com cardiopatia congênita entre seis e 18 anos de idade. Foi realizado o teste de caminhada de 6 minutos para avaliar a capacidade funcional, e aplicou-se a versão curta do Questionário Internacional de Atividade Física (IPAQ) para avaliar os níveis de atividade física. Foram feitos também: exame ecocardiográfico, coleta de sangue para avaliação de perfil metabólico e inflamatório (glicemia, triglicerídeos, colesterol total, lipoproteína de alta densidade - HDL-colesterol, lipoproteína de baixa densidade - LDL-colesterol, hemograma completo, proteína C reativa, insulina). Resultados: Foram avaliados 25 indivíduos, dos quais 14 tinham cardiopatia congênita acianótica e 11 cianótica. A média de idade foi de 12,0±3,7 anos, e 20 (80%) eram do sexo masculino. O IPAQ mostrou que seis (24%) indivíduos eram muito ativos, oito (32%) eram ativos, nove (36%) tinham atividade física irregular e dois (8%) eram sedentários. A média de distância percorrida no teste de caminhada dos 6 minutos, considerando todos os indivíduos estudados, foi de 464,7±100,4 m, sendo 181,4±42,0 m menor do que o previsto (p=0,005). Encontrou-se correlação entre o escore Z do teste de caminhada de 6 minutos e o número de procedimentos cirúrgicos realizados (r=-0,455; p=0,022). Conclusões: Crianças e adolescentes com cardiopatia congênita têm baixa capacidade funcional, mas não são completamente sedentários.

ABSTRACT

Abstract Background: Children with familial hypercholesterolemia may develop early endothelial damage leading to a high risk for the development of cardiovascular disease (CVD). Statins have been shown to be effective in lowering LDL cholesterol levels and cardiovascular events in adults. The effect of statin treatment in the pediatric population is not clearly demonstrated. Objective: To systematically review the literature to evaluate the effects of different statins and dosages in total cholesterol levels in children and adolescents with familial hypercholesterolemia. We also aimed to evaluate statin safety in this group. Methods: PubMed, EMBASE, Bireme, Web of Science, Cochrane Library, SciELO and LILACS databases, were searched for articles published from inception until February 2016. Two independent reviewers performed the quality assessment of the included studies. We performed a meta-analysis with random effects and inverse variance, and subgroup analyses were performed. Results: Ten trials involving a total of 1543 patients met the inclusion criteria. Our study showed reductions in cholesterol levels according to the intensity of statin doses (high, intermediate and low): (-104.61 mg/dl, -67.60 mg/dl, -56.96 mg/dl) and in the low-density lipoprotein cholesterol level: [-105.03 mg/dl (95% CI -115.76, -94.30), I2 19.2%], [-67.85 mg/dl (95% CI -83.36, -52.35), I2 99.8%], [-58.97 mg/dl (95% CI -67.83, -50.11), I2 93.8%. The duration of statin therapy in the studies ranged from 8 to 104 weeks, precluding conclusions about long-term effects. Conclusion: Statin treatment is efficient in lowering lipids in children with FH. There is need of large, long-term and randomized controlled trials to establish the long-term safety of statins.


Resumo Fundamentos: Crianças com hipercolesterolemia familiar podem desenvolver dano endotelial precoce, aumentando o risco de desenvolver doenças cardiovasculares. As estatinas tiveram sua eficácia em diminuir níveis de colesterol LDL e eventos cardiovasculares em adultos comprovada. O efeito das estatinas na população pediátrica não está claramente demonstrado. Objetivo: Revisar sistematicamente a literatura para avaliar os efeitos e a segurança de diferentes estatinas e suas dosagens nos níveis de colesterol total em crianças e adolescentes com hipercolesterolêmica familiar. Métodos: Artigos publicados desde o início até fevereiro de 2016 foram pesquisados nas bases PubMed, EMBASE, Bireme, Web of Science, Cochrane Library, SciELO e LILACS. Dois revisores independentes avaliaram a qualidade dos estudos incluídos. Realizamos meta-análise com efeitos aleatórios e variância inversa. Análises de subgrupos foram realizadas. Resultados: Dez ensaios envolvendo 1.543 pacientes preencheram os critérios de inclusão. Em nosso estudo, as análises demostraram reduções nos níveis de colesterol, de acordo com a intensidade das doses de estatina (alta, intermediária e baixa): (-104,61 mg/dl, -67,60 mg/dl, -56,96 mg/dl) e no nível de lipoproteínas de baixa densidade: [-105,03 mg/dl (IC95% -115.76, -94.30), I2 19.2%], [-67.85 mg/dl (IC95% -83.36, -52.35), I2 99.8%], [-58.97 mg/dl (IC95% -67.83, -50.11), I2 93,8%. A duração da terapia com estatina variou de 8 a 104 semanas, impedindo conclusões sobre os efeitos a longo prazo. Conclusão: O tratamento com estatinas é eficiente na redução de lipídios em crianças com hipercolesterolemia familiar. É necessário realizar ensaios controlados randomizados de longo prazo para estabelecer a segurança do uso de estatinas a longo prazo.

ABSTRACT

Abstract Objective Brazil is a large, heterogeneous, and diverse country, marked by social, economic, and regional inequalities. Stillbirth is a global concern, especially in low- and middle-income countries. This study investigated the prevalence and possible determinants of stillbirth in different regions of Brazil. Methods This is a cross-sectional study including all women of reproductive age who had had a pregnancy in the last five years, enrolled in the most recent Brazilian Demographic and Health Survey (DHS/PNDS-2006/07). Logistic regression was used to assess the association between region and other maternal characteristics and stillbirth risk. Results The prevalence of stillbirth in Brazil was 14.82 per 1000 births, with great variation by region of the country, and a higher prevalence among the most deprived. The North and Northeast regions had the highest odds of stillbirth compared to the Center-West, which persisted after adjustment for multiple confounders - including deprivation level and ethnicity. Low maternal age and maternal obesity were also related to higher odds of stillbirth. Conclusion In Brazil, the region influences stillbirth risk, with much higher risk in the North and Northeast. Variation in socioeconomic level does not explain this finding. Further research on the subject should explore other possible explanations, such as antenatal care and type of delivery, as well as the role of the private and public health systems in determining stillbirth. Preventive strategies should be directed to these historically disadvantaged regions, such as guaranteeing access and quality of care during pregnancy and around the time of birth.


Resumo Objetivo O Brasil é um país grande, heterogêneo e diverso, marcado por desigualdades sociais, econômicas e regionais. A natimortalidade é uma preocupação global, principalmente em países de renda baixa e média. Este estudo investigou a prevalência e os possíveis determinantes da natimortalidade em diferentes regiões do Brasil. Métodos Estudo transversal que incluiu todas as mulheres em idade reprodutiva que estiveram grávidas nos últimos cinco anos registradas na Pesquisa Nacional sobre Demografia e Saúde (PNDS-2006/07). A regressão logística foi usada para avaliar a relação entre região e outras características maternas e risco de natimortalidade. Resultados A prevalência de natimortos no Brasil foi de 14,82 a cada 1.000 nascimentos, com grande variação de acordo com a região do país e uma prevalência mais alta entre as mais precárias. As regiões Norte e Nordeste tiveram as taxas de natimortalidade mais altas em comparação com a região Centro-Oeste, que perdurou após o ajuste das diversas variáveis de confusão - inclusive nível de pobreza e etnia. A baixa idade e a obesidade maternas também estavam relacionadas a taxas de natimortalidade mais elevadas. Conclusão No Brasil, a região influencia o risco de natimortalidade, com riscos muito mais altos no Norte e no Nordeste. A variação no nível de pobreza não explica esse achado. Futuras pesquisas sobre o assunto devem explorar outras possíveis explicações, como cuidado pré-natal e tipo de parto, bem como o papel dos sistemas de saúde público e privado com relação à natimortalidade. As estratégias de prevenção devem ser direcionadas a essas regiões historicamente desfavorecidas, como garantir acesso e qualidade da assistência durante a gravidez e perto do momento do nascimento.

ABSTRACT

Abstract Background: Children and adolescents with congenital heart disease often have alterations in their exercise capacity that can be evaluated by various functional testing. Objective: To evaluate the functional capacity of children and adolescents with congenital heart disease (CHD) with systematic review and meta-analyses. Methods: The review included observational studies, data from the first evaluation of randomized clinical trials or observational follow-up periods after clinical trials which evaluated functional capacity by cardiopulmonary exercise test, stress testing, six-minute walk test or step test, in children and adolescents with CHD, aged between six and 18 years, and comparisons with healthy controls in the same age group. The quantitative assessment was performed by meta-analysis, by comparing the maximal oxygen consumption (VO2max) of children and adolescents with CHD and respective control groups. Results: Twenty-five of 2.683 studies identified in the search met the inclusion criteria. The VO2max measurement showed that patients with CHD have a decrease of 9.31 ml/Kg/min (95% CI. -12.48 to -6.13; I2, 94.3%, P for heterogeneity < 0.001) compared with the control group. The meta-analysis of the data of maximum heart rate (HR) reached during cardiopulmonary test and stress testing, retrieved from 18 studies, showed a HR value of -15.14 bpm (95% CI. -20.97 to -9.31; I2, 94.3%, P for heterogeneity < 0.001) compared with the control group. Conclusion: Children and adolescents with CHD have lower VO2max and HR compared to controls.


Resumo Fundamento: Crianças e adolescentes com cardiopatia congênita frequentemente apresentam alterações na sua capacidade de exercício que pode ser avaliada através de vários testes funcionais. Objetivo: Avaliar a capacidade funcional de crianças e adolescentes com cardiopatias congênitas (CC) através de revisão sistemática e metanálise. Métodos: A revisão incluiu estudos observacionais, dados da primeira avaliação de ensaios clínicos randomizados ou acompanhamento após ensaios clínicos que avaliaram a capacidade funcional através teste de exercício cardiopulmonar, teste ergométrico, teste de caminhada de seis minutos ou teste do degrau em crianças e adolescentes. Foram incluídos indivíduos com CC, idade entre seis e 18 anos e seus controles saudáveis. A avaliação quantitativa foi realizada por metanálise, comparando o consumo máximo de oxigênio (VO2max) entre crianças e adolescentes com CC e seus pares saudáveis. Resultados: Vinte e cinco dos 2.683 estudos identificados na pesquisa atenderam aos critérios de inclusão. A medida do VO2máx mostrou que os pacientes com CC apresentaram uma diminuição de 9,31 ml/Kg/min (IC 95%: -12,48 a -6,13; I2, 94,3%, P para heterogeneidade < 0,001) em comparação ao grupo controle. A metanálise dos dados de frequência cardíaca máxima (FCM) alcançada durante o teste de exercício cardiopulmonar e teste ergométrico, avaliado por 18 estudos, mostrou um valor de -15,14 bpm (IC 95%: -20,97 a -9,31; I2; 94,3%, P para heterogeneidade < 0,001) em comparação ao grupo controle. Conclusão: Crianças e adolescentes com CC apresentam menor VO2máx e FCM em relação a controles saudáveis.

ABSTRACT

Summary Objective: To verify the knowledge about food and nutrition and its association with the nutritional status of obese patients with noncommunicable diseases (NCDs), and to identify the relationship between information sources and level of knowledge. Method: Cross-sectional study that included 263 outpatients of a cardiology referral hospital in Porto Alegre, Rio Grande do Sul, Brazil. The participants filled out a questionnaire on socioeconomic data and knowledge about food and nutrition and had their nutritional status evaluated by body mass index (BMI), waist circumference (WC) and waist-hip ratio (WHR). Results: BMI showed a significant inverse association with the percentage of correct answers (p=0.002), as well as WC (p=0.000) and WHR (p<0.001). This was also true for education (p<0.001) and female gender (p=0.005) compared to males. More than 60% of patients reported using television and 23% reported using newspaper as sources of nutritional information. Conclusion: Our study revealed a significant association between BMI and the level of knowledge about foods, showing that there is need for more information on obesity-related NCDs for greater understanding by patients.


Resumo Objetivo: Verificar os conhecimentos sobre alimentação e nutrição e sua associação com o estado nutricional de pacientes obesos portadores de doenças crônicas, e identificar a relação das fontes de informação com o nível de conhecimentos. Método: Estudo transversal realizado com 263 pacientes ambulatoriais de um hospital de referência em cardiologia em Porto Alegre, RS. Os indivíduos preencheram um questionário sobre dados socioeconômicos e conhecimentos sobre alimentação e nutrição, tendo seu estado nutricional avaliado por meio de índice de massa corporal (IMC), circunferência da cintura (CC) e relação cintura quadril (RCQ). Resultados: O IMC apresentou associação inversa e significativa com o percentual de acertos (p=0,002), assim como a CC (p<0,001) e a RCQ (p<0,001). E também a escolaridade (p<0,001) e o sexo feminino (p=0,005) em relação ao masculino. Mais de 60% dos pacientes relataram utilizar televisão e 23% jornal como fontes de informação sobre alimentação. Conclusão: No presente estudo, houve associação significativa entre IMC e nível de conhecimento sobre alimentação, demonstrando que há necessidade de maior divulgação sobre as doenças crônicas não transmissíveis (DCNT) para que haja maior entendimento por parte dos pacientes.

ABSTRACT

Fundamentos: A hipertensão arterial é um importante fator de risco para desfechos cardiovasculares. No entanto, na maioria dos centros de Atenção Primária à Saúde, a pressão arterial permanece com níveis de controle inadequados. A Monitorização Ambulatorial da Pressão Arterial (MAPA) é uma ferramenta útil na predição de morbidade e mortalidade cardiovascular. A implementação da MAPA de 24 horas e a avaliação dos desfechos cardiovasculares na Atenção Primária à Saúde podem ser eficazes para melhorarem estratégias de acompanhamento do paciente hipertenso neste cenário. Objetivo: Avaliar hipertensão não controlada detectada pela MAPA de 24 horas como um preditor de desfechos cardiovasculares em pacientes hipertensos da Atenção Primária à Saúde em um ambiente de baixos recursos. Métodos: Estudo de coorte com base em centros de Atenção Primária à Saúde. O estudo foi conduzido com 143 pacientes hipertensos, que realizaram MAPA de 24 horas no início do estudo. Os alvos terapêuticos foram baseados no Eighth Joint National Committee, na Diretriz Brasileira de Hipertensão e na Diretriz Europeia de Hipertensão. Registros médicos de emergência, admissões hospitalares e atestados de óbitos foram revisados. Resultados: A amostra foi constituída por 143 pacientes que preencheram os critérios de inclusão. Após 4 anos de seguimento foram verificados 17 óbitos, 12 novos casos de fibrilação atrial e 37 internações hospitalares relacionadas a desfechos cardiovasculares. Durante o período de acompanhamento, a MAPA de 24 horas apresentou resultado preditor para novos casos de fibrilação atrial (p = 0,015) e combinação de desfechos cardiovasculares, mortalidade e admissões hospitalares (p = 0,012)


Background: Arterial hypertension is an important risk factor for cardiovascular outcomes. However, in most Primary Health Care centers, blood pressure remains at inadequate control levels. Ambulatory Blood Pressure Monitoring (ABPM) is a useful tool in predicting cardiovascular morbidity and mortality. The implementation of 24-hour ABPM and evaluation of cardiovascular outcomes in Primary Health Care may be effective in improving strategies for monitoring hypertensive patients in this setting. Objective: To evaluate uncontrolled arterial hypertension detected by 24-hour ABPM as a predictor of cardiovascular outcomes in hypertensive patients from Primary Health Care in a low-resource environment. Methods: Cohort study based on primary health care centers. The study was carried out with 143 hypertensive patients, who underwent 24-hour ABPM at baseline. Therapeutic targets were based on the Eighth Joint National Committee, the Brazilian Hypertension Guideline, and the European Hypertension Guideline. Medical records of emergency care, hospital admissions, and death certificates were reviewed. Results: The sample consisted of 143 patients who met the inclusion criteria. After 4 years of follow-up, there were 17 deaths, 12 new cases of atrial fibrillation and 37 hospital admissions related to cardiovascular outcomes. During the follow-up period, the 24-hour ABPM showed a predictive result for new cases of atrial fibrillation (p = 0.015) and a combination of cardiovascular outcomes, mortality, and hospital admissions (p = 0.012). Conclusion: The 24-hour ABPM was an important predictor of cardiovascular outcomes in a hypertensive population that seeks assistance in Primary Health Care centers

ABSTRACT

Abstract Background: Schools have become a key figure for the promotion of health and obesity interventions, bringing the development of critical awareness to the construction and promotion of a healthy diet, physical activity, and the monitoring of the nutritional status in childhood and adolescence. Objectives: To describe a study protocol to evaluate the effectiveness of an intervention designed to improve knowledge of food choices in the school environment. Methods: This is a cluster-randomized, parallel, two-arm study conducted in public elementary and middle schools in Brazil. Participants will be children and adolescents between the ages of 5 and 15 years, from both genders. The interventions will be focusing on changes in lifestyle, physical activities and nutritional education. Intervention activities will occur monthly in the school's multimedia room or sports court. The control group arm will receive usual recommendations by the school. The primary outcome variable will be anthropometric measures, such as body mass index percentiles and levels of physical activity by the International Physical Activity Questionnaire. Results: We expect that after the study children will increase the ingestion of fresh food, reduce excessive consumption of sugary and processed foods, and reduce the hours of sedentary activities. Conclusion: The purpose of starting the dietary intervention at this stage of life is to develop a knowledge that will enable for healthy choices, providing opportunities for a better future for this population.


Resumo Fundamento: As escolas tornaram-se essenciais para a promoção de saúde e de intervenções para obesidade, propiciando o desenvolvimento de consciência crítica para a construção e promoção de dieta saudável, atividade física e monitoramento do status nutricional na infância e adolescência. Objetivos: Descrever um protocolo de estudo para avaliar a eficiência de uma intervenção projetada para aprimorar o conhecimento sobre escolhas alimentares no ambiente escolar. Métodos: Estudo clínico randomizado em cluster, paralelo, de dois braços, conduzido em escolas públicas de ensino fundamental e médio no Brasil. Os participantes serão crianças e adolescentes entre 5 e 15 anos de idade, dos dois sexos. As intervenções se concentrarão em mudanças de estilo de vida, atividade física e educação nutricional. As atividades de intervenção ocorrerão mensalmente na sala de multimídia ou quadra de esportes das escolas. O grupo controle receberá as recomendações usuais através da escola. O desfecho primário será a mudança nas medidas antropométricas, como índice de massa corporal e os níveis de atividade física conforme o Questionário Internacional de Atividade Física. Resultados: Esperamos que, após o estudo, as crianças aumentem o consumo de alimentos frescos, reduzam o consumo excessivo de alimentos açucarados e processados, e reduzam as horas gastas em atividades sedentárias. Conclusão: O propósito de iniciar a intervenção dietética nessa fase da vida é desenvolver o conhecimento que permitirá escolhas saudáveis, propiciando oportunidades para um melhor futuro para essa população.
