A TRAINING COURSE ON BIOETHICS FOR FAMILY HEALTH STRATEGY PROFESSIONALS IN SANTO ANDRE, SP

This case report presents the experience of a training course on bioethics for nurses and physicians of the Family Health Strategy in Santo Andre, SP. This study is based on problem-based learning and deliberative bioethics, and aimed at presenting the deliberation procedure as a means of handling ethical issues. Contents were addressed in a cross-section manner through five sequential activity sessions at two different moments of concentration with one dispersion interval. In the first moment of concentration, key concepts and deliberative bioethics contents were developed. The second involved deliberation sessions on moral conflicts, which were selected and prepared during the dispersion interval. Participants evaluated the deliberation as an appropriate instrument to deal with the ethical issues they are faced with. Problem-based learning was an effective educational strategy for continuing education in deliberative bioethics.

Implications of maternal nutrient restriction in transgenerational programming of hypertension and endothelial dysfunction across F1-F3 offspring

Aims: An extensive variety of prenatal insults are associated with an increased incidence of metabolic and cardiovascular disorders in adult life. We previously demonstrated that maternal global nutrient restriction during pregnancy leads to increased blood pressure and endothelial dysfunction in the adult offspring. This study aimed to assess whether prenatal exposure to nutritional insult has transgenerational effects in F-2 and F-3 offspring. Main methods: For this, female Wistar rats were randomly divided into two groups on day 1 of pregnancy: a control group fed standard chow ad libitum and a restricted group fed 50% of the ad libitum intake throughout gestation. At delivery, all animals were fed a standard laboratory chow diet. At 11 weeks of age, one female and one male from each restricted litter were randomly selected and mated with rats from another restricted litters in order to generate the F-2 offspring. The same procedure produced F-3 generation. Similarly, the rats in the control group were bred for each generation. Key Findings: Our findings show that the deleterious effects of maternal nutrient restriction to which the F-0 mothers were exposed may not be limited to the male first generation. In fact, we found that elevated blood pressure, an impaired vasodilatory response to acetylcholine and alterations in NO production were all transferred to the subsequent males from F-2 and F-3 generations. Significance: Our data show that global nutrient restriction during pregnancy results in a specific phenotype that can be passed transgenerationally to a second and third generation.
