Sousa,Tanara Rosangela Vieira; Leite Filho,Paulo Amilton Maia;
Revista de Saúde Pública , 2008, DOI: 10.1590/S0034-89102008005000047
Abstract: objective: to assess health status determinants in brazil's northeast states. methods: study carried out based on panel data analysis of aggregated information for municipalities. data was obtained from the united nations development program atlas of human development and brazilian national treasury department for the years 1991 and 2000. health status indicator was infant mortality rate and health determinants were the following variables: per capita health and sanitation expenditure; number of physicians per inhabitant; access to drinking water; fertility rate; illiteracy rate; percentage of adolescent mothers; per capita income; and gini coefficient. results: infant mortality rates in northeast brazil were reduced by 31.8%, during the period studied, slightly above the national average. however, in some states, such as rio grande do norte, bahia, ceará and alagoas, the reduction was more significant. this can be attributed to improvement in some indicators that are main determinants of infant mortality rate reduction: greater access to education, reduction of fertility rates, increased income, and access to drinking water. conclusions: brazilian states that showed greater gains in access to drinking water, education, income and reduction of fertility rates were also the ones that achieved major reductions in mortality of children under a year of age.

Jacinto,Paulo de Andrade; Tejada,César Augusto Oviedo; Sousa,Tanara Rosangela Vieira de;
Revista de Saúde Pública , 2010, DOI: 10.1590/S0034-89102010000200011
Abstract: objective: to analyze the relationship between macroeconomic conditions and health in brazil. methods: the analysis of the impact of employment and income on mortality in brazil was based on panel data from brazilian states between 1981 and 2002. mortality rates obtained from the national mortality database was used as a proxy for health status, whereas the variables employment, income, and illiteracy rates were used as proxies for macroeconomic and socioeconomic conditions. static and dynamic models were applied for the analysis of two hypotheses: a) there is a positive relationship between mortality rates and income and employment, as suggested by ruhm; b) there is a negative relationship between mortality rates and income and employment, as suggested by brenner. results: there was found a negative relationship between mortality rates (proxy for health) and macroeconomic conditions (measured by employment rate). the estimates indicated that the overall mortality rate was higher during economic recession, suggesting that as macroeconomic conditions improved, increasing employment rates, there was a decrease in the mortality rate. the estimate for the relationship between illiteracy (proxy for education level) and mortality rate showed that higher levels of education can improve health. conclusions: the results from the static and dynamic models support brenner's hypothesis that there is a negative relationship between mortality rates and macroeconomic conditions.

Lima Filho, José de Melo;Lessa, Rosangela;Stosic, Borko;Duarte Neto, Paulo José;Vieira, José Wilson;
Brazilian Archives of Biology and Technology , 2006, DOI: 10.1590/S1516-89132006000300008
Abstract: external morphological distinction between young selene vomer and s. brownii (carangidae) was studied using multivariate analysis with the purpose to evaluate if other characters than the second dorsal and pelvic fin spines could be used as distinguishing attributes for juveniles fishes. these spines are important distinctive morphological characters, but they can be absent in juvenile fishes or be broken during manipulation. a sample of 389 specimens was collected from beach netting at cai?ara do norte (rn), northeastern brazil, in 2001. each specimen was digitalized and their images provided numerical matrices using scion image and fantomas software. a c-language program was developed and used to calculate 16 euclidean distances and nine homologous landmarks plotted on images. discriminant analysis results revealed that the two selene species was clearly distinguished employing morphometric procedures of diagonally oriented measurements of the antero-posterior body axis.
A multicommuted flow procedure for the determination of total and free cholesterol in eggs and human blood serum by chemiluminescence
Leite, Oldair D;Vieira, Heberth J;Fatibello-Filho, Orlando;Rocha, Fábio R. P;
Journal of the Brazilian Chemical Society , 2010, DOI: 10.1590/S0103-50532010000900017
Abstract: a multicommuted flow-based procedure with detection by chemiluminescence for the determination of total and free cholesterol without changes in the flow manifold is proposed. cholesterol esterase and cholesterol oxidase were both immobilized on glass beads via glutaraldehyde/(3-aminopropyl)-triethoxysilane and mini-columns containing the enzymes were used for online sample treatment. cholesterol esters were cleaved to cholesterol and fatty acids at the packed reactor containing cholesterol esterase. the reactor containing cholesterol oxidase converted cholesterol to cholest-4-en-3-one also yielding hydrogen peroxide. detection was based on the chemiluminescence produced by h2o2 in the hexacyanoferrate(iii)-luminol system. influence of both chemical and hydrodynamic variables on the chemiluminescence signals were investigated. the analytical curves were linear from 250 to 2500 mg l-1 and from 500 to 4000 mg l-1, for free and total cholesterol, respectively. detection limits for both analytes were estimated as 60 mg l-1 at 99.7% confidence level. the sampling rate was 55 h-1 and reagent consumption was 350 μg of luminol and 2.6 mg of potassium hexacyanoferrate(iii) per determination. the procedure developed was successfully applied for determination of cholesterol in eggs and in human blood serum with results in agreement with the reference spectrophotometric method at the 95% confidence level.

Einstein (S?o Paulo) , 2009,
Abstract: Objective: To report on the experience of implementing ultrasound-assisted Menghini technique in the evaluation of liver transplant dysfunction. Methods: Menghini technique uses a suction needle, through percutaneous access, allowing a fast puncture (less than one second), which can help reduce the incidence of complications. Rresults: A total of 87 biopsies performed with 16-gauge suction needles were studied in a period of 15 months. Ultrasound was used to access the presence of perihepatic liquid or collections, biliary and vascular disorders, to mark a safe puncture site and for post-procedure control. The main biopsy indication was elevation of liver enzymes. In 81 cases, one fragment was collected and satisfactory samples were obtained in 85 procedures (97.7%). Minor complications occurred in six patients (6.9%), five with local pain and one with vagal reaction. There was a major complication (1.1%), hemothorax, which was diagnosed by clinical and radiological control examination and then treated. Cconclusions: Menghini technique to obtain liver tissue is quick, effective and safe, but it has always to follow the general care aspects of any intervention procedure. The ultrasound before and after the procedure helps marking an appropriate puncture site, may enhance the effectiveness of the method and is useful to identify possible early complications.

Einstein (S?o Paulo) , 2009,
Abstract: Objective: To report the experience with percutaneous biopsies of pancreatic grafts guided by ultrasonography. Methods: Series of cases referred from outpatient’s clinic for biopsy of pancreas transplant, between December 2006 and March 2008. Data were collected from medical electronic records for age, sex and histopathology. The indication for the procedure was obtained from medical and laboratory records. Doppler ultrasonography was performed for control and to guide biopsy in real time. Rresults: Twenty patients referred for biopsy of their transplanted pancreas over a one-year period were evaluated. In one patient, biopsy was not performed for having no safe access for ultrasound. It was used 18 gauge needles, mostly automatic-cut type. The main indications were increased blood glucose and pancreatic enzyme levels as well as reduction of urinary amylase. The sonographic aspect of the pancreatic graft was normal in 18 cases. In all 19 biopsies performed, satisfactory samples for histopathological study were obtained. There were no complications. Cconclusions: This series of cases demonstrated low sensitivity and specificity of ultrasound in diagnosis of pancreatic transplants disorders, but showed to be very useful to guide transplanted pancreas biopsies. Although no complications occurred in this experience, the risk-benefit relation should always be assessed for every patient.

Arquivos Brasileiros de Cardiologia , 2003,
Abstract: OBJECTIVE: To evaluate the impact of the use, prior to the procedure, of injectable diltiazem to prevent complications. METHODS: Between September 2000 and July 2001, 50 patients underwent transradial coronary angiography and were randomized to receive placebo (GI) or diltiazem (GII) through a catheter inserted into the radial artery. All patients received isosorbide mononitrate. Ultrasound analyses of the radial artery were performed before examination, 30 minutes afterwards, and 7 days afterwards to evaluate the flow, the diameter, and the artery output. RESULTS: The radial artery diameter of GI was 2.4± 0.5 mm before the procedure and 2.3±0.5 mm after 30 minutes (NS), whereas in GII the diameter was 2.2±0.3 mm before the examination and 2.5±0.4 mm 30 minutes after it (P<0.001). Radial artery output in group 1 was 7.3±5.l2 mL/min before the examination and 6.1±3.5 mL/min 30 minutes after the examination (NS), and GII had an increase of 5.9±2.5 mL/min before examination to 9.05± 7.78 mL/min after the examination (P=0.04). Complications (spasm, occlusion, and partial obstruction) occurred in 4 patients (17.4%) in GI and did not occur in GII (P=0.04). CONCLUSION: The study suggests a decrease in vascular complications through the transradial access for coronary angiography with the use of diltiazem as an antispasmodic drug, resulting in the significant increase in the diameter of the radial artery and radial artery output.

Geotextos : Revista da Pós-Gradua??o em Geografia da Universidade Federal da Bahia , 2010,
Abstract: Este artigo analisa a metrópole brasiliense em seu atual estágio de desenvolvimento, o qual n o se desvincula do processo de urbaniza o brasileiro no ambito da mundializa o. Nessa condi o, a produ o do espa o torna-se cada vez mais subordinada aos circuitos da valoriza o dos capitais que, devido a isso, amplia e aprofunda a fragmenta o de parcelas do espa o em sincronia com sua própria escassez (na qual claramente se apresentam as contradi es da sociedade moderna) do solo urbano. O método de análise articulou os pressupostos teóricos do empreendedorismo urbano às propostas de reestrutura o urbanística do Projeto Orla para compreender a constru o deste novo espa o. Os resultados obtidos revelaram a estreita vincula o entre a prática da política urbana e a prática econ mica (principalmente na extens o do setor imobiliário e terciário moderno) no processo de urbaniza o do Plano Piloto.
