ABSTRACT
Resumo Os adolescentes são considerados grupo vulnerável e exposto a diferentes ameaças à saúde, tornando-se necessária a discussão sobre aspectos éticos relacionados a sua participação em pesquisa e prática clínica. Por meio de revisão integrativa de literatura foram selecionados estudos que abordaram aspectos bioéticos relacionados à vulnerabilidade de adolescentes nos últimos quinze anos. Nove artigos atenderam aos critérios pré-estabelecidos para o estudo e foram agrupados em três categorias: 1) trabalhos que pontuaram a compreensão psicológica e cognitiva do adolescente ao participar de pesquisa científica; 2) estudos que enfatizaram aspectos relacionados a decisões médicas; e 3) estudos que abordaram a temática da sexualidade na adolescência. Após análise dos estudos selecionados, verificou-se que não é possível chegar a consenso válido para todas as situações que envolvem adolescentes em pesquisa e prática clínica.
Abstract Adolescents are considered vulnerable and exposed to different threats to health group, making it necessary discussion about ethical aspects related to their participation in research and clinical practice. The employed methodology was an integrative literature review and it was selected studies that approached the subject "bioethical matters related to vulnerability of adolescents" within the last fifteen years. Nine articles included the pre-established criteria to the study, grouped into three categories: 1) works that mentioned the psychological-cognitive comprehension of adolescent to participate in scientific research; 2) works emphasizing aspects related to medical decisions; and 3) studies approaching the issue of sexuality in adolescence. The analysis of selected studies found out it is not possible to reach a valid consensus to all situations involving adolescents in research and clinical practice.
Resumen Los adolescentes son considerados como grupo vulnerable y expuesto a diferentes amenazas en el ámbito de la salud, por lo cual es necesario que exista un debate sobre los aspectos éticos relacionados con su participación en la investigación y en la práctica clínica. Por medio de una revisión integradora de la literatura, se seleccionaron estudios que abordaban aspectos bioéticos relacionados con la vulnerabilidad de los adolescentes en los últimos quince años. Nueve artículos contemplaban los criterios preestablecidos para el estudio y se agruparon en tres categorías: 1) trabajos que contemplaban la comprensión psicológica y cognitiva del adolescente al participar en la investigación científica; 2) estudios que enfatizaban los aspectos relacionados con las decisiones médicas; y 3) estudios que abordaban la sexualidad en la adolescencia. Después del análisis de los estudios seleccionados, se verificó que no es posible llegar a un consenso válido para todas las situaciones que involucran adolescentes en la investigación y en la práctica clínica.

The aim of this study was to evaluate the effects of resistance exercise, such as weight-lifting (WL) on the biochemical parameters of lipid metabolism and cardiovascular disease risk in the rats fed casein (control) or whey protein (WP) diets. Thirty-two male Fisher rats were randomly assigned to sedentary or exercise-trained groups and were fed control or WP diets. The WL program consisted of inducing the animals to perform the sets of jumps with weights attached to the chest. After seven weeks, arteriovenous blood samples were collected for analysis. The WL or WP ingestion were able to improve the lipid profile, reducing the TC and non-HDL cholesterol concentrations, but only WP treatment significantly increased the serum HDL concentrations, thereby also affecting the TC/HDL and HDL/non-HDL ratios. However, WL plus WP was more effective in improving the HDL/non-HDL ratio than the exercise or WP ingestion alone and the body weight gain than exercise without WP ingestion.
