Correlato hormonal do comportamento reprodutivo de machos de sagüi comum (Callithrix jacchus) em ambiente natural

Contrary to what is recorded for Callithrix jacchus females, the social interactions and hormonal profiles of males are less studied, and mainly in wild groups. The goal of this study was to investigate the behavioral and endocrine profiles of reproductive (RMs) and non-reproductive (NRs) common marmoset adult free-ranging males living in two natural groups (GC1 and GR2). The groups inhabited the area of the Escola Agrícola de Jundiaí/UFRN, located in Macaíba, Brazil. Fecal collection for cortisol and androgen measurement and behavioral monitoring was carried out during the active phase from April to September, 2005. For behavioral data collection the focal instantaneous method was used every 5 min, for a total of 11.563 records. Statistical analysis was performed using non parametric tests and p < 0.05. Besides showing diurnal variation, the frequency of affiliative behaviors was significantly higher for RMs toward reproductive females than for NRs. Affiliative interactions of RMs with both reproductive females and NRs were similar, probably related to pair bond formation and helper recruitment, respectively. Parental care was also similar for both RMs and NRs. Both androgen and cortisol levels increased after the birth of the infants, mainly in RMs. The longitudinal profile of androgens fluctuates more in response to agonistic encounters and sexual behavior than that of cortisol. The mean basal excretion of both hormones was significantly higher in RMs and seems to reflect their higher participation in territorial vigilance and mate guarding behaviors. Significant positive correlations were found between agonism and cortisol and androgen hormones. These results describe, for the first time, the behavioral and hormonal profiles of common marmosets living in free-ranging groups and suggest that reproductive males are more responsive both behaviorally and hormonally to social group dynamics

Ações educativas com portadores de diabetes Mellitus através da educação popular em saúde

Popular Health Education in its emancipatory dimension refers to individuals and groups to exchange knowledge and experiences, allowing them to associate health to the outcomes of their living conditions. Under this view, health workers and health users are subjects of the educative process. Thus, this study aims to identify the key clinical and socio sanitary attributes and promote educational activities with patients with Diabetes Mellitus (DM) in a Family Health Care Unit of the Western Sanitary District, in the city of Natal / RN. It is an action research which uses the references of the Theory of Liberating Education, which is based on a problem-solving pedagogy and that values dialogue in the process of understanding oneself and the world. Thirty-six diabetics, who are residents of the area covered by the health care unit, and thirty health workers participated in the survey. Each group had an average of twelve participants, and the meetings took place at the Unit´s hall, using conversation wheels, group dynamics, life narratives, experiences telling, movie exhibition and discussions, music, knowledge telling, desires, limitations, beliefs and values socially constructed. Data collection took place during the second half of two thousand and thirteen through Free Word Association Technique (FWAT), recordings of conversation wheels, participative observation, group dynamics, testimonies, questionnaires, life narratives and photographs. The empirical material was organized and subjected to three analyzes: thematic content (Bardin), textual statistics analysis by software IRAMUTEQ (Ratinaud), and photographic analysis (Edmund Feldman). The data analyses originated words, expressions, categories, themes and creative situations showing that popular health education is in process of construction, but still very incipient in primary care. The National Policy on Popular Health Education shows us the necessary ways for the transformation of health practices and the build of a more shared and solidary society. The meetings could be place to reverse that normative logic that has been happening over the years in primary care, but that by itself is not enough. It is possible to conclude that the use of active practices, increasing of listening and training on Popular Health Education will enable changes in the scenario where users and health workers deal with diabetes mellitus. Thus we see the popular health education is being timidly incorporated to the educational process of the subjects involved in this study, and far away from the principles of participation, organization of political work, increase opportunities for dialogue, respect, solidarity and tolerance among different actors involved in addressing the health problems that are fundamental to the improvement in building healthy practices of primary care
