ABSTRACT
In this document, the Inter-American Committee of Cardiovascular Prevention and Rehabilitation, together with the South American Society of Cardiology, aimed to formulate strategies, measures, and actions for cardiovascular disease prevention and rehabilitation (CVDPR). In the context of the implementation of a regional and national health policy in Latin American countries, the goal is to promote cardiovascular health and thereby decrease morbidity and mortality. The study group on Cardiopulmonary and Metabolic Rehabilitation from the Department of Exercise, Ergometry, and Cardiovascular Rehabilitation of the Brazilian Society of Cardiology has created a committee of experts to review the Portuguese version of the guideline and adapt it to the national reality. The mission of this document is to help health professionals to adopt effective measures of CVDPR in the routine clinical practice. The publication of this document and its broad implementation will contribute to the goal of the World Health Organization (WHO), which is the reduction of worldwide cardiovascular mortality by 25% until 2025. The study group's priorities are the following: • Emphasize the important role of CVDPR as an instrument of secondary prevention with significant impact on cardiovascular morbidity and mortality; • Join efforts for the knowledge on CVDPR, its dissemination, and adoption in most cardiovascular centers and institutes in South America, prioritizing the adoption of cardiovascular prevention methods that are comprehensive, practical, simple and which have a good cost/benefit ratio; • Improve the education of health professionals and patients with education programs on the importance of CVDPR services, which are directly targeted at the health system, clinical staff, patients, and community leaders, with the aim of decreasing the barriers to CVDPR implementation.
Com este documento, o Comitê Interamericano de Prevenção e Reabilitação Cardiovascular, em posição conjunta com a Sociedade Sul-Americana de Cardiologia, mostra seu interesse no desenvolvimento de estratégias, medidas e intervenções para a prevenção e a reabilitação cardiovascular. Com o objetivo de implementar na América Latina uma política de saúde regional e nacional dos países membros, tem-se o objetivo de promover a saúde cardiovascular e, consequentemente, diminuir a morbimortalidade. O grupo de estudos em Reabilitação Cardiopulmonar e Metabólica do Departamento de Exercício, Ergometria e Reabilitação Cardiovascular de Sociedade Brasileira de Cardiologia (DERC/SBC) criou uma comissão de experts para revisar a versão em português e adaptá-la à realidade nacional. Este documento tem como missão principal auxiliar os profissionais de saúde a alcançarem medidas efetivas de prevenção e reabilitação cardiovascular (RCV) na prática clínica diária. Com a difusão deste documento, bem como com a sua implementação de forma mais abrangente, contribuiremos com a meta da Organização Mundial de Saúde de diminuir a mortalidade cardiovascular no mundo em 25% até o ano de 2025. As prioridades deste grupo de trabalho são: • Enfatizar o caráter prioritário da RCV como instrumento de prevenção secundária com importante impacto na morbimortalidade cardiovascular; • Unir esforços para melhorar o conhecimento da RCV, sua difusão e aplicação na maioria dos centros e institutos cardiovasculares da América do Sul, priorizando a utilização de um método de prevenção cardiovascular integral, prático, de fácil aplicação e de custo/benefício comprovado; • Melhorar a educação do pessoal da saúde e dos pacientes por meio de programas educativos dirigidos, que permitam envolver diretamente os sistemas de saúde, pessoal médico, pacientes e líderes comunitários sobre a importância dos serviços de RCV, a fim de diminuir as barreiras para a sua implantação.

The role of airway inflammation in ventilated preterm newborns and the risk factors associated with the development of chronic lung disease are not well understood. Our objective was to analyze the association of the airway inflammatory response in ventilated preterm infants by serial measurements of TNF-a and IL-10 in tracheobronchial lavage (TBL) with perinatal factors and lung function measured early in life. A series of TBL samples were collected from ventilated preterm infants (less than 32 weeks of gestational age) and concentrations of TNF-a and IL-10 were measured by ELISA. Pulmonary function tests were performed after discharge by the raised volume rapid compression technique. Twenty-five subjects were recruited and 70 TBL samples were obtained. There was a significant positive association between TNF-a and IL-10 levels and length of time between the rupture of the amniotic membranes and delivery (r = 0.65, P = 0.002, and r = 0.57, P < 0.001, respectively). Lung function was measured between 1 and 22 weeks of corrected age in 10 patients. Multivariable analysis with adjustment for differences in lung volume showed a significant negative association between TNF-a levels and forced expiratory flow (FEF50; r = -0.6; P = 0.04), FEF75 (r = -0.76; P = 0.02), FEF85 (r = -0.75; P = 0.03), FEF25-75 (-0.71; P = 0.02), and FEV0.5 (r = -0.39; P = 0.03). These data suggest that TNF-a levels in the airways during the first days of life were associated with subsequent lung function abnormalities measured weeks or months later.

Wheezing associated with respiratory viral infections in infancy is very common and results in high morbidity worldwide. The Th1/Th2 pattern of immune response in these patients remains unclear and previous studies have shown controversial results. The aim of the present study was to compare the type of Th1/Th2 cytokine response between infants with acute bronchiolitis, recurrent wheezing and upper respiratory infections from a developing country. Infants younger than 2 years of age admitted to Hospital São Lucas, Porto Alegre, RS, Brazil, between May and November 2001, with an acute episode of wheezing associated with viral respiratory infection were selected. Subjects with upper respiratory infections from the emergency department were selected for the control group. Interferon-gamma (IFN-gamma) and interleukin-4 (IL-4) levels from nasal aspirates were determined by ELISA from peripheral mononuclear cell cultures. Twenty-nine subjects with acute bronchiolitis, 18 with recurrent wheezing and 15 with upper respiratory infections were enrolled. There were no differences in family history of atopy or parental smoking between groups. Oxygen requirement was similar for the acute bronchiolitis and recurrent wheezing groups. The percentage of positive tests for the cytokines studied and the IFN-gamma/IL-4 ratio was similar for all groups. Comparison of the polarized Th1/Th2 cytokine results for the various groups showed no specific pattern of cytokine production. Infants with wheezing from a developing country do not show any specific predominant pattern of Th1/Th2 cytokine production, suggesting that multiple factors may be involved in the pathogenesis of this illness.
