The right to scientific information: one of the main elements of the unified health system

 Citizen care in the health field is a fundamental right provided by the federal constitution of Brazil. The Unified Health System (SUS) is one of the best and most important systems in the world and serves around 220 million people. The System is comprehensive and characterized by three pillars of support: universality, completeness and equity. The right to scientific information is one of the main elements of the SUS and the Journal of Human Growth and Development has contributed over its 27 years of existence providing a democratic scenario and a place to debate ideas in the field of public health and the irrefutable defence of SUS in Brazil. In this way, JHGD maintains its tradition of publishing articles devoted to the field of public health and contributing to the dissemination of knowledge and to the progress of science. The Journal intends to serve as a space for exchange knowledge among professionals in universities and help them to deal with the problems of human growth and development, improving the publication scenario of scientific articles refereed by peers, highlighting its commitment to communicate the knowledge obtained through ethic research with bilingual and free publications.The Citizen care in the health field is a fundamental right provided by the federal constitution of Brazil.

Degree of risk related to procedures performed in conjunction with surgical myocardial revascularization in octogenarians

INTRODUCTION/OBJECTIVES: We determined the degree of risk produced by the association of other surgical procedures with surgical myocardial revascularization in octogenarian patients and identified the risk factors that best explain hospital mortality. METHODS: This study was an observational analytical historical cohort study involving octogenarians operated on at our institution between January 1, 2000 and January 1, 2005. We stratified the objective population as follows: Group 1 comprised octogenarians revascularized without associated procedures, and Group 2 comprised octogenarians revascularized with associated procedures. Statistical analyses included the t test for independent samples and multiple logistic regression analysis. Significance was accepted with an alpha error of 5%. RESULTS: Univariate analyses revealed the following clinical and statistically significant variables: hospital mortality (P=0.002), diabetes mellitus (P=0.017), preoperative endocarditis (P=0.001), cardiogenic shock (P=0.019), use of an intra-aortic balloon pump (P=0.026), preoperative risk score (Parsonnet), P<0.001, procedure associated with revascularization (P<0.001), medium number of affected coronary arteries (P<0.001), use of extracorporeal circulation (P<0.001), time of extracorporeal circulation (P<0.001), number of distal anastomoses (P=0.002), graft type (P<0.001), postoperative breathing support (P<0.001), stroke (P<0.001), infection (P=0.002), creatinine level (P=0.018), and quality of life score (P=0.050). DISCUSSION/CONCLUSIONS: In octogenarian patients, the need for a procedure associated with surgical myocardial revascularization produces an absolute increase in hospital mortality risk of 45%. The variables that contributed to hospital mortality were preoperative endocarditis, preoperative cardiogenic shock, the use of extracorporeal circulation, the length of time of extracorporeal circulation, postoperative creatinine level, and postoperative need for prolonged respiratory support

Morfologia macroscópica e morfometria do aparelho urogenital do macaco de cheiro (Saimiri sciureus Linnaeus, 1758)

Descrevem-se macroscopicamente o aparelho urogenital em quatro animais da espécie Saimiri sciureus, jovens, nascidos em cativeiro junto ao Centro Nacional de Primatas. A vulva delimitou-se pelos lábios vulvares, apresentando um clitóris bem desenvolvido com aspecto fálico. O vestíbulo vaginal é bastante curto, com espessa parede muscular, estendendo-se da rima da vulva até o óstio da vagina. A vagina vem logo na sequência do vestíbulo, sendo constituída por um tubo muscular com aspecto alongado e achatado dorsoventralmente, com paredes finas, estando disposta entre o vestíbulo vaginal e a cérvix, sendo esta última relativamente curta, porém, com musculatura bem desenvolvida. O útero é simples, com fundo globoso, estando localizado na porção caudal da cavidade abdominal. As tubas uterinas mostraram-se longas e retilíneas, ligando-se aos ovários, que são grandes e elipsóides, com superfície lisa
