Abstract The training, recruitment and retention of primary care professionals is a constant challenge in Brazil. The recent expansion of family and community medicine residency programs in the country coexists with gaps in the literature on the effects of this process. This article explores municipal health managers’ understanding of these programs and the role they play in professional training and improving the quality of health care. We conducted a quantitative and qualitative analysis of the responses to questionnaires answered by 48 health managers working in municipal health services affiliated to residency programs. A descriptive statistical analysis of the quantitative data was performed and the qualitative data were analyzed using thematic analysis. The findings show that efforts were made to incorporate family and community doctors into the health care network and that managers recognized the potential residency program have to improve the quality of care and enhance professional training. Weaknesses were found in actions to improve infrastructure and facilities and the organization of the services affiliated to the programs. This study highlights the potential of residency programs for addressing longstanding problems in primary health care in Brazil when combined with actions to strengthen services, human resources and the programs.

ABSTRACT We provide an updated list of the vascular epiphytic flora occurring in native environments of Uruguay based on literature review, herbarium specimens, and fieldwork throughout the country. The catalogue provides standardized information for each species, including accepted name, synonyms used within Uruguay, epiphytic category, distribution within the country, habitat, conservation status, observations, and a voucher citation. The effort documented 73 species for the epiphytic flora of Uruguay (3 % of the flora), distributed among 29 genera and 12 families. Bromeliaceae was the richest family (17), followed by Polypodiaceae (16) and Orchidaceae (12). Tillandsia stood out as the most speciose genus with 15 species. Characteristic holoepiphytes was the most diverse ecological category. More than half of the epiphytic species documented for Uruguay (53 %) reach their southernmost geographic distribution in the country, whereas only two mostly epipetric species of Tillandsia - T. arequitae and T. uruguayensis - are endemic to the country. Almost half of the epiphytic species found are presently under categories of threat of extinction, with 60 % of them occurring in national protected areas. Both the richest epiphytic families and the predominance of characteristic holoepiphytes coincide with findings from floristic and ecological studies previously carried out in humid subtropical regions.

ABSTRACT We evaluated the influence of hesperidin and vitamin C (VitC) on glycemic parameters, lipid profile, and DNA damage in male Wistar rats treated with sucrose overload. Rats were divided into six experimental groups: I-water control; II-sucrose control; III-hesperidin control; IV-VitC control; V-co-treatment of sucrose plus hesperidin; VI-co-treatment of sucrose plus VitC. We measured the levels of triglycerides, total cholesterol, HDL-c, LDL-c, fasting glucose, and glycated hemoglobin (A1C). DNA damage was evaluated in blood and brain cells using the comet assay and the micronucleus test was used to evaluate chromosomal damages in the rat bone marrow. Co-treatment with VitC, but not with hesperidin, normalized the serum glucose. No effect of co-treatments was observed on A1C. The co-treatment with VitC or hesperidin did not influence the lipid profile (p>0.05). Rats co-treated with hesperidin had a significantly lower DNA damage level in blood (p<0.05) and brain (p<0.05). Rats treated with VitC only, but not those co-treated with VitC plus sucrose, had significantly higher DNA damage in brain (p<0.05). No significant differences were observed in the results of micronucleus test (p>0.05). Hesperidin and VitC showed different effects on sucrose and DNA damage levels. While VitC lowered the serum glucose, hesperidin reduced the DNA damage.

ABSTRACT The purpose of this study was to determine the effects of the high consumption of sucrose on the levels of DNA damage in blood, hippocampus and bone marrow of rats. Male Wistar rats were treated for 4 months with sucrose (10% for 60 initial days and 34% for the following 60 days) in drinking water, and then, glycemia and glycated hemoglobin (A1C) were measured. Levels of DNA damage in blood and hippocampus were evaluated by the comet assay. The micronucleus test was used to evaluate chromosomal damages in the bone marrow. The sucrose treatment significantly increased (p<0.01) the serum glucose levels (~20%) and A1C (~60%). The level of primary DNA damage was significantly increased (p<0.05) in hippocampal cells (~60%) but not in peripheral blood leukocytes (p>0.05). Additionally, it was observed a significative increase (p<0.05) in the markers of chromosomal breaks/losses in bone marrow, as indicated by the micronucleus test. This is the first study that evaluated DNA damage induced by high sucrose concentration in the hippocampus and bone marrow of rats. Sucrose-induced DNA damage was observed in both tissues. However, the mechanism of sucrose toxicity on DNA remains unknown.

Contar com um conhecimento adequado da flora é fundamental para o desenvolvimento de investigação em diversos campos disciplinares. Neste contexto, nosso trabalho surge da necessidade de atualizar e melhorar a informação disponível sobre a flora lenhosa nativa do Uruguai. Nossos objetivos são determinar objetivamente a flora lenhosa uruguaia (arbustos e árvores), avaliar a completude do inventário e explorar sua similaridade com regiões vizinhas. Ao analisar a flora do Uruguai, produzimos definições operacionais de arbustos e árvores e obtivemos uma lista de 313 espécies (57 famílias, 124 gêneros). Usando 7.418 registros de distribuição, geramos curvas acumulativas de riqueza de espécies para estimar o potencial máximo de riqueza de espécies em escala nacional e local. Concluímos que a completude a nível nacional é elevado (89-95%), mas em escala local é menor e bastante heterogêneo. Existem ainda grandes áreas sem dados ou com pouca informação. Encontramos que as espécies arbóreas do Uruguai, comparativamente, apresentam similaridade elevada com a Província de Entre Rios (Argentina), média com a Província de Buenos Aires (Argentina) e baixa com o Rio Grande do Sul (Brasil). Conclui-se que a riqueza de árvores e arbustos da flora uruguaia é maior do que a esperada para uma região de pradarias, e as diferenças encontradas nos indíces de similaridade com as floras lenhosas vizinhas estimulam estudos futuros para reavaliar o esquema fitogeográfico da região.

Adequate knowledge of a flora is fundamental for furthering research in several disciplines. In this context, our work arises from the necessity to update and improve available information on the native woody flora of Uruguay. The goals of this study were to objectively determine the Uruguayan native woody flora (shrub and trees), to evaluate its inventory completeness, and to explore its similarity with neighboring regions. By analyzing the Uruguayan flora we produced working definitions of shrubs and trees, and obtained a list of 313 species (57 families, 125 genera). Using 7418 distribution records, we generated cumulative species richness curves to estimate maximum species richness at national and local scales. We conclude that the completeness at the national level is high (89-95%), but at the local scale is lower and quite heterogeneous. There are still large areas without data or with little information. We found that comparatively, the similarity between Uruguayan tree species and the Province of Entre Ríos (Argentina) was high, while similarity with the Province of Buenos Aires (Argentina) was medium, and with Rio Grande do Sul (Brazil) was low. In conclusion, richness of tree and shrub species of the Uruguayan flora is greater than expected for a grassland region, and the differences found in the similarity index with the neighboring woody floras will stimulate future studies to reevaluate phytogeographic schemes of the region.
