Abstract: Neste artigo temos por objetivo analisar o que vem sendo denominado de determinantes sociais da saúde (DSS). Trata-se de uma pesquisa bibliográfica, na qual recorremos aos estudos de alguns autores que tratam o assunto, em uma tentativa de releitura a partir dos fundamentos marxistas. Em uma contraposi o à teoria dos DSS, resgatamos as bases da "quest o social" para demonstrarmos qual é a determina o essencial da problemática da saúde. Vimos que as abordagens teóricas sobre os DSS tratam os problemas sociais como se fossem fragmentos da realidade que ganham autonomia. Porém, na verdade, eles constituem uma quest o una - a "quest o social" - com sua base material (e também humano-social) imbricada no processo de trabalho tal qual ele é desenvolvido no capitalismo. Portanto, é no processo de acumula o capitalista que encontramos a determina o essencial para a problemática da saúde e, desse modo, a sua solu o requer a dissolu o da ordem societária burguesa. In this article we analyze what has been called the Social Determinants of Health (SDH). This is a literature review in which we turn to the some authors who deal on the subject in an attempt to reconsider the theme under the marxist theory. In contrast to the theory of SDH, we recovered the foundations of the "social issues", seeking to demonstrate the essential determination of health issues. We have seen that the theoretical approach of the SDH deal with social problems as if they were fragments of reality that gain autonomy. Nevertheless, in reality they are a single question - the "social issues" - with its material origin (and also human and social) intertwined to the work process such as it is established under capitalism. Therefore, it is in the process of capital accumulation that we find the essential determination of health issues and hence its solution requires the dissolution of the bourgeois social order.

Abstract: Eighteen Anglonubian (n = 9) and Saanen (n = 9) goats were monitored by ultrasonography to characterize the follicular dynamic after induced estrus by progestagen treatment during seasonal anoestrous. In both breeds, the progesterone level reached values above 1.0 ng.ml-1 at D3 and decreased below this value at D18. Among Anglonubian goats, 33.3, 44.5, and 22.2%, respectively, showed two, three and four follicular waves while among Saanen goats 87.5% showed three and 12.5% showed two follicular waves. In both breeds differences among the days of emergence follicular waves, as well among the days that the biggest follicle of each wave reached maximum diameter were detected (P>0.05). In the goats which presented three waves pattern, the emergence day of first, second and third wave occurred at days 2.0 ± 0.9; 9.3 ± 1.4 e 15.1 ± 0.8 versus 1.0 ± 0.5; 6.7 ± 0.9 e 14.6 ± 1.0 in Anglonubian and Saanen, respectively. In the early-mid luteal phase (D8 to D10) the progesterone concentration was higher in four waves goats than two and three waves goats (P<0.05). The utilization of exogenous progestagen for estrous induction, during seasonal anestrous had no effect on subsequent follicular dynamic pattern in dairy goats. However, the endogenous progesterone levels in the mid luteal phase affect the turnover of dominant follicles, consequently, interfering on the number of follicular waves. Dezoito cabras Anglonubiana (n = 9) e Saanen (n = 9) foram monitoradas por ultra-sonografia com o objetivo de caracterizar a dinamica folicular após estro induzido com progestágeno durante anestro estacional. Nas duas ra as o nível de progesterona alcan ou valores acima de 1,0 ng.mL-1, no D3, e declinou abaixo desse valor, no D18. Entre as cabras Anglonubiana, 33,3%; 44,5 e 22,2% apresentaram, respectivamente, duas, três e quatro ondas, enquanto entre as Saanen, 87,5% apresentaram três e 12,5% duas ondas foliculares. Nas duas ra as, foram verificadas diferen as entre os dias de emergência das ondas foliculares e entre os dias em que o maior folículo de cada onda atingiu o diametro máximo (P<0,05). Nas cabras que apresentaram o padr o de três ondas, o dia de emergência da primeira, segunda e terceira ondas ocorreu nos dias 2,0 ± 0,9; 9,3 ± 1,4 e 15,1 ± 0,8 versus 1,0 ± 0,5; 6,7 ± 0,9 e 14,6 ± 1,0 nas Anglonubiana e Saanen, respectivamente. No inicio da fase luteal média (D8-D10), as cabras de quatro ondas apresentaram concentra es de progesterona superiores às de duas e três ondas (P<0,05).

Abstract: Objective: to describe the socio-economic-cultural pregnant women who use outpatient prenatal care and identify the themes of education for the pregnancy and puerperal period elected by women. Methods: it’s a cross-sectional, exploratory and descriptive study. In a prenatal care from healthcare center located in Rio de Janeiro were carried out 90 semi-structured interviews with pregnant women. This study was approved by Research Ethics Committee in Health Municipal Secretariat-RJ, number of register 231/08. Results: the predominant age group (48%) was that of pregnant women 18 to 25 years, most (62%) did not complete high school and are employed in the service sector. The absolute majority (94%) have family income less than three minimum wages. The most women (76%) did not plan the current pregnancy and 33% had previous abortion. Some women were drinking alcohol (13.3%) and smoking (7.7%). Signs and symptoms of labor was the theme of education elected by the majority (56%). Conclusion: to understand the socio-economic and cultural allowed be identified vulnerabilities to the health of women. This research has great relevance to support the planning of health care. Through health education we can contribute to a good outcome of pregnancy and future pregnancies and to reduce the rates of maternal and neonatal mortality.

Cunha, Daniel Ferreira da;Cunha, Selma Freire de Carvalho da;Reis, Marlene Ant?nia dos;Teixeira, Vicente de Paula Antunes;
Arquivos Brasileiros de Cardiologia , 2002, DOI: 10.1590/S0066-782X2002000400005
Abstract: objective: to compare the heart weight and the heart weight/body weight coefficient of adults with and without chronic malnutrition. methods: in an initial case series of 210 autopsies performed in adults, we recorded body and heart weights and calculated the heart weight/body weight coefficients (hw/bw x 100). the exclusion criteria were as follows: positive serology for chagas' disease, edema, obesity, heart diseases, hepatopathies, nephropathies, and systemic arterial hypertension. malnutrition was characterized as a body mass index <18.5kg/m2. differences with p<0.05 were considered significant. results: individuals in the malnourished (n=15) and control (n=21) groups were statistically different, respectively, in regard to body mass index (15.9±1.7 versus 21.3±2.5kg/m2), heart weight (267.3±59.8 versus 329.1±50.4g), and the hw/bw coefficient (0.64±0.12 versus 0.57±0.09%). a positive and significant correlation was observed between heart weight and body mass index (r=0.52), and between heart weight and body weight (r=0.65). conclusion: malnourished individuals have lighter hearts and a greater hw/bw coefficient than non-malnourished individuals do. these findings indicate a possible preservation of the myocardium in relation to the intensity of weight loss associated with the probable relative increase in cardiac connective tissue and heart blood vessels.
