Verani, José Fernando de S.;Maranho, Eduardo P.;Laender, Fernando;
Cadernos de Saúde Pública , 1993, DOI: 10.1590/S0102-311X1993000100004
Abstract: this article describes the process by which some concepts of epidemiological surveillance are elaborated and turned into operational categories to comprise the so-called epidemiologial surveillance system for two specific diseases. the authors describe some epidemiological concepts and categories which were elaborated over the course of the smallpox eradication program and more recently in the poliomyelitis eradication program. such concepts and categories as outbreak containment, cross-notification, and case definitions are described as they fit into a series of actions which make up the epidemiological surveillance system. finally, it is worth noting that the description developed in this article is based on personal observations, since the authors participated in the smallpox eradication program in bangladesh and somalia as well as in the regional poliomyelitis eradication program in the americas.

Abstract: background: the scarce amount of data available in brazil on the economic burden of cardiovascular diseases (cvd) does not justify the growing concern in regard to the economic burden involved. objective: the present study aims at estimating the costs of severe cvd cases in brazil. methods: cases of severe cvd were estimated based on hospitalized cases lethality and total cvd mortality rates. national data bases and sample studies were used to estimate costs of hospitalization, outpatient care, and social security benefits. loss of income was estimated from the burden of disease in brazil data. results: approximately two million cases of severe cvd were reported in 2004 in brazil. that accounts for 5.2% of the population over 35 years of age. the resulting annual cost was at least r$ 30.8 billion (36.4% for health care, 8.4% for social security and employers' reimbursements, and 55.2% due to loss in productivity). that corresponded to r$ 500.00 per capita (considering 35 year-old and older population) and r$ 9,400.00 per patient. direct costs with health care from severe cvd cases accounted for 8% of total national expenditure on health and 0.52% of 2004 gnp (r$ 1,767 billion = us$ 602 billion). that corresponded to an yearly average direct cost of r$182.00 per capita (r$ 87.00 from public resources) and of r$ 3,514.00 per case. conclusion: total annual costs per severe cvd case were estimated to be significant. costs per capita and total costs corresponding to this sub-group of cvd patients are expected to escalate as the population ages and the prevalence of severe cases increases.

Abstract: the annotation and comparative analyses of the genomes of mycoplasma synoviae and mycoplasma hyopneumonie, as well as of other mollicutes (a group of bacteria devoid of a rigid cell wall), has set the grounds for a global understanding of their metabolism and infection mechanisms. according to the annotation data, m. synoviae and m. hyopneumoniae are able to perform glycolytic metabolism, but do not possess the enzymatic machinery for citrate and glyoxylate cycles, gluconeogenesis and the pentose phosphate pathway. both can synthesize atp by lactic fermentation, but only m. synoviae can convert acetaldehyde to acetate. also, our genome analysis revealed that m. synoviae and m. hyopneumoniae are not expected to synthesize polysaccharides, but they can take up a variety of carbohydrates via the phosphoenolpyruvate-dependent phosphotransferase system (pep-pts). our data showed that these two organisms are unable to synthesize purine and pyrimidine de novo, since they only possess the sequences which encode salvage pathway enzymes. comparative analyses of m. synoviae and m. hyopneumoniae with other mollicutes have revealed differential genes in the former two genomes coding for enzymes that participate in carbohydrate, amino acid and nucleotide metabolism and host-pathogen interaction. the identification of these metabolic pathways will provide a better understanding of the biology and pathogenicity of these organisms.

Abstract: in order to identify methods of recuperation of degraded pastures in the agreste of pernambuco, an experiment was conducted in the fazenda riacho do papaguaio, municipial district of s?o jo?o. it was used a split-plot feature within a confounded randomized block design. the experimental treatments were four recovery managements (deferment, deferment + harrowing, deferment + harrowing + corn as a companion crop, deferment + corn as a companion crop), two levels of nitrogen (0 and 100 kg/ha of n), two levels of phosphorus (0 and 100 kg/ha of p2o5), totalizing 16 experimental treatments with three replications. the harvesting evaluation was taken after 138 days from implementation of the experimental treatments. a significant n and p2o5 interaction was observed with marked increase in forage dry matter mass corresponding to the combination of 100 kg/ha of n and p2o5. the deferment and deferment + corn treatments resulted in higher forage mass yield as compared to the harrowing ones. after 138 days of growth, there was an increase in the percentage of uncovered soil with plow use, while the opposite was true without the use of a plow. plowing did not demonstrate agronomic viability as a degraded pasture recuperation practice. allowing the pasture to rest for 138 days during the rainy season promoted its recuperation, primarily with the combined application of nitrogen and phosphate fertilizers. the recovery of nitrogen and phosphate fertilized brachiaria decumbens stapf. was associated with decrease of other species.

Abstract: soils developed at semi-arid climate can present salt accumulation, which compromise the agricultural use, being increased by inadequate irrigation management. based on the use, the degradation of these soils can occur at higher or smaller intensity. this study aimed to evaluate the effect of soil uses based on physical and chemical properties of an irrigated area in the semi-arid region of northeastern brazil. the soil uses were annual crops (c), fruticulture (f), pasture (p), discarded lands (d), or native vegetation (v). disturbed soil samples were collected from the 0-10, 10-30 and 30-60 cm layers for chemical analysis, and undisturbed samples from the first two layers for soil density analysis. the indicators ph and electrical conductivity of the saturation extract, soil ph, available phosphorus, total organic carbon, exchangeable cations, calcium, magnesium, potassium, and sodium, cation exchange capacity, sum of bases, base saturation percentage, percentage of exchangeable sodium, and carbon stocks were subjected to multivariate analysis by principal component analysis, and clustering by the tocher method. the soil chemical properties under production systems was different from v; the chemical quality of the production systems c and d, and that of c and p was similar. for the uses c, d, p, and f, the values of the soil properties (ph, ph and electrical conductivity of the saturation extract, exchangeable calcium and magnesium, sum of bases, base saturation and available phosphorus) was higher than for v in the three analyzed layers. the highest total organic carbon content was observed under f and p. the electrical conductivity of the saturation extract was higher under c, d and p than under f and v, indicating the beginning of a soil salinization process, thus characterizing them as less sustainable land uses.

Abstract: steel and composite (steel-concrete) highway bridges are currently subjected to dynamic actions of variable magnitude due to convoy of vehicles crossing on the deck pavement. these dynamic actions can generate the nucleation of fractures or even their propagation on the bridge deck structure. proper consideration of all of the aspects mentioned pointed our team to develop an analysis methodology with emphasis to evaluate the stresses through a dynamic analysis of highway bridge decks including the action of vehicles. the design codes recommend the application of the curves s-n associated to the miner's damage rule to evaluate the fatigue and service life of steel and composite (steel-concrete) bridges. in this work, the developed computational model adopted the usual mesh refinement techniques present in finite element method simulations implemented in the ansys program. the investigated highway bridge is constituted by four longitudinal composite girders and a concrete deck, spanning 40.0m by 13.5m. the analysis methodology and procedures presented in the design codes were applied to evaluate the fatigue of the bridge determining the service life of the structure. the main conclusions of this investigation focused on alerting structural engineers to the possible distortions, associated to the steel and composite bridge's service life when subjected to vehicle's dynamic actions.
