Ideal Cardiovascular Health in adolescents: Findings from Study of Cardiovascular Risks in Adolescents.

BACKGROUND AND AIM: We assessed the Ideal Cardiovascular Health (CVH) in Brazilian adolescents according to demographics and socioeconomic characteristics. METHODS AND RESULTS: This is a cross-sectional study with data from the Study of Cardiovascular Risks in Adolescents (ERICA), with a nationwide representative sample of 36,956 Brazilian adolescents, aged 12-17 years, enrolled in public and private schools. The CVH metrics considered were body mass index (BMI), physical activity, smoking, healthy diet score, blood pressure, fasting plasma glucose, and total cholesterol. The demographics and socioeconomic characteristics analyzed were sex, age, race/skin color, and type of school attended. The study design was considered, and the significant difference determined by the non-overlapping of 95% Confidence Interval. The mean ideal CVH score was 4.0, higher for females, adolescents aged 15-17 years, and students from private schools. The prevalence of ideal fasting plasma glucose was 96%, of non-smoking 95.6%, of ideal blood pressure 75.5%, of ideal BMI 73.2%, of ideal total cholesterol 55.4%, of ideal physical activity 45.2%, and only 0.5% had an ideal diet. The prevalence of ideal CVH metrics varied according to demographics and socioeconomic characteristics. CONCLUSION: Females, older adolescents, and students who attended private school had a better CVH. Demographics and socioeconomic characteristics were associated with CVH metrics. The low ideal proportions found for diet and physical activity are of concern and reinforce the need for food and nutritional educational actions designed to promote healthy behaviors in adolescence to prevent the development of cardiovascular diseases.

Beverage consumption in Brazil: results from the first National Dietary Survey.

OBJECTIVE: To provide an overview of beverage consumption patterns using the first nationally representative survey of dietary intake in Brazil. DESIGN: Beverage consumption data were obtained by 1 d food records in an individual dietary survey. SETTING: Nationwide cross-sectional survey, 2008-2009. SUBJECTS: Nationally representative sample of individuals aged ≥10 years (n 34 003). RESULTS: Beverages contributed 17.1 % of total energy consumption. Caloric coffee beverages provided the greatest level of energy overall (464 kJ (111 kcal)/d). Individuals aged 10-18 years (243 kJ (58 kcal)/d) and 19-39 years (230 kJ (55 kcal)/d) consumed a higher proportion of energy from sugar-sweetened soft drinks than individuals over this age (142 kJ (34 kcal)/d for those aged 40-59 years and 79 kJ (19 kcal)/d for those aged ≥60 years). CONCLUSIONS: Overall, the contribution of beverages, particularly sugary beverages, to total energy consumption in Brazil represents an important public health challenge and is comparable with those from other countries.

Preoperative education in cholecystectomy in the context of a multimodal protocol of perioperative care: a randomized, controlled trial.

BACKGROUND: Preoperative education is a key point in multimodal protocols of perioperative care. We investigated whether preoperative education for patients undergoing open cholecystectomy would reduce the incidence of perioperative symptoms. METHODS: This was a randomized, single-blinded, clinical trial that included adult (18-65 years old) candidates for elective open cholecystectomy. All patients took part in the ERAS/ACERTO protocol of perioperative care except that only the intervention group received preoperative education. The main endpoints of the study were the presence and intensity of postoperative symptoms (e.g., nausea, vomiting, pain) measured by a visual analogue scale, 24 h after the operation. RESULTS: A total of 74 patients (34 in the intervention group, 40 in the control group) completed the study. The intervention group had significantly lower median (interquartile range) scores for nausea [0 (4) vs. 2.5 (5.8), p = 0.04] and pain [0.2 (2.3) vs. 3.1 (3.45), p < 0.01] than the controls. High well-being (score ≥ 6) was reported by 79.4 % (27 patients) of the intervention group in contrast to 57.5 % (23 patients) of the controls (p = 0.04). CONCLUSIONS: Preoperative education is highly effective in the context of a multimodal protocol for enhancing the recovery of patients submitted to open cholecystectomy.

Restricted dietary pattern may contribute to lowering blood pressure in adolescents with obesity: Study of Cardiovascular Risk in Adolescents.

OBJECTIVE: Dieting is one of the main target factors for interventions that seek to control and prevent rising blood pressure. This study identified dietary patterns and analyzed their association with adolescents' blood pressure. METHODS: This is a cross-sectional study with a probabilistic and nationally representative sample of adolescents aged 12-17 years, who participated in the Study of Cardiovascular Risk in Adolescents (ERICA), carried out in 2013-2014 with Brazilian adolescents (N = 36 956). Food consumption was assessed by 24 h recall. Dietary patterns were identified using the Reduced Rank Regression method, and considering waist circumference, fasting insulin, and dietary polyunsaturated fat/saturated fat ratio as intermediate variables. Multiple linear regression models stratified by weight were developed; SBP and DBP were the dependent variables, and dietary pattern scores were the independent ones, with adjustment for potential confounding factors. RESULTS: The following patterns were identified: 'Brazilian common', 'Restricted' and 'Added sugar'. The 'Restricted' pattern, which included diet/light foods, chicken and chicken-based dishes, leafy greens, vegetables and spices, red meats and dishes based on red meats and tubers, was inversely associated with SBP (ß = -1.55; 95% CI = -2.26 to -0.83) and DBP (ß = -1.19; 95% CI = -1.70 to -0.68) in adolescents with obesity. CONCLUSION: In adolescents with obesity, a low-energy density diet was associated with reduced blood pressure. These findings are consistent with international recommendations for preventing elevated blood pressure.

Triple therapy in chronic hepatitis C: initial series in a public health program in the South of Brazil.

BACKGROUND: Chronic hepatitis C has great impact on world's health. Current therapy for genotype 1 hepatitis C virus includes protease inhibitors boceprevir and telaprevir, associated to standard therapy - peginterferon alfa + ribavirin. There are no published data in Brazil on the results of this new therapy, and it is interesting an evaluation of what was accomplished up to this moment. Objectives To evaluate virologic response to triple therapy, as well as the safety profile and tolerability. METHOD: This study is a clinical series of patients receiving triple therapy for C hepatitis in a single center of a Public Health System of South Brasil. Out of the 121 patients that initiated the triple therapy, the first patients that finished the treatment and evaluated the sustained virological response (24 weeks after the end of treatment) were included. RESULTS: Twenty four genotype 1 chronic hepatitis C monoinfected patients were included. Nineteen (79.2%) patients had been previously treated. Thirteen (54.2%) patients were cirrhotic. Nineteen (79.2%) patients completed the planned therapy. By the end of the treatment, 14 (58.3%) out of 24 patients had undetectable viral load. Sustained virologic response occurred in 12 (50.0%) out of 24 patients, 07 (58.3%) in telaprevir group and 05 (41.7%) in boceprevir group. Out of 24 patients under triple therapy, 58% (n=14) presented anemia. CONCLUSIONS: In conclusion, despite the small number of patients treated with triple therapy evaluated in the current study, it possibly reflects the population under this therapy in real-life.

Contexto A hepatite crônica pelo vírus C tem grande impacto na saúde mundial. A terapia atual do genótipo 1 inclui os inibidores de protease (IP) boceprevir e telaprevir, associados à terapia padrão - alfapeginterferona + ribavirina (PR). No Brasil ainda não há estudos publicados sobre os resultados dessa nova terapia, sendo de interesse uma avaliação do que foi realizado até o momento. Objetivos Avaliar a resposta virológica ao tratamento triplo, bem como o perfil de segurança e tolerabilidade. Métodos O estudo consta de série de casos dos pacientes em uso de terapia tripla para o tratamento da hepatite C em um polo de tratamento da Secretaria Estadual da Saúde do Estado do Rio Grande do Sul, Brasil. Dentre os 121 pacientes que estão em uso de terapia tripla (PR e IP) foram apresentados os dados referentes aos primeiros que finalizaram o tratamento e realizaram avaliação da resposta virológica sustentada na semana 24 pós-tratamento. Resultados Foram incluídos 24 pacientes monoinfectados por hepatite C crônica genótipo 1. Dezenove (79%) pacientes eram previamente experimentados. Treze (54,2%) pacientes apresentavam cirrose. Dezenove (79,2%) pacientes completaram o tratamento planejado. Ao final do tratamento, 14 (58,3%) dos 24 pacientes apresentaram carga viral indetectável. Resposta virológica sustentada ocorreu em 12 (50%) dos 24 pacientes, sendo 07 (58,3%) no grupo telaprevir e 05 (41,7%) no grupo boceprevir. Dos 24 pacientes submetidos à terapia tripla, 58% (n=14) apresentaram anemia. Conclusões Embora o presente estudo tenha avaliado um pequeno número de casos, possivelmente reflete a população submetida à terapia tripla na vida real, despida das restrições dos estudos de registro. .

Identificação de miocárdio viável pela tomografia computadorizada / Identification of myocardial viability by computed tomography

A pesquisa da viabilidade miocárdica ainda é um importante aspecto da avaliação de pacientes com suspeita de apresentar doença arterial coronaria e, também, no planejamento do tratamento de diversos subgrupos de pacientes. Diversas técnicas não invasivas são utilizadas neste sentido, com sucesso, mas ainda não existem dados definitivos sobre a superioridade relativa destes exames. A tomografia computadorizada por múltiplos detectores, por outro lado, apresenta potencial de ser empregada neste sentido, pois o exame apresenta elevada resolução espacial e é usado de modo efetivo como parte da investigação incruenta de pacientes com suspeita de doença arterial coronária. Duas técnicas são disponíveis atualmente: uma objetiva avaliar o grau de opacificação da parede miocárdica na fase arterial do fluxo de contraste. Outro protocolo tenta determinar a presença de realce tardio, a exemplo do que é feito pela ressonância magnética. Diferentes trabalhos sugerem que ambas podem ser utilizadas com eficácia e que poderia até complementar a investigação destes casos. O progresso do conhecimento e da tecnologia permite também fazer estas imagens com segurança crescente. Trabalhos adicionais são necessários para determinar o real papel da tomografia neste cenário, mas os resultados preliminares são animadores.
