OBJETIVO: avaliar a prevalência e os fatores de risco associados à morbidade materna grave numa maternidade terciária. MÉTODOS: trata-se de um estudo de corte transversal dos casos de morbidade materna grave atendidos no Hospital e Maternidade Celso Pierro entre outubro de 2005 e julho de 2006, identificados a partir dos livros de controle das unidades de internação, pronto atendimento e centro obstétrico. Foram estudadas gestantes e puérperas que apresentavam condições definidoras de morbidade materna grave a partir dos diagnósticos clínicos segundo critérios propostos por Waterstone. Posteriormente, os casos de maior gravidade clínica, chamados de morbidade extremamente grave, foram reclassificados utilizando-se os critérios definidores de Mantel, baseados em disfunção orgânica e manejo. RESULTADOS: foram identificadas 114 mulheres com morbidade materna grave entre 2.207 partos, com razão de outra morbidade grave e morbidade extremamente grave de 44,9 e 6,8 casos por 1.000 partos, respectivamente. A média da idade gestacional no parto foi de 35 semanas e 87% das mulheres vieram de área de cobertura da maternidade no município. A hipertensão (pré-eclâmpsia grave) representou 96% de outras morbidades graves e a hemorragia esteve presente em 60% dos casos de morbidade extremamente grave, seguida de hipertensão. A prevalência de morbidade extremamente grave entre os casos de morbidade grave não se associou com estado marital, escolaridade, idade materna, tipo de parto, gestações, idade gestacional e distrito de saúde de moradia. CONCLUSÕES: as outras morbidades graves foram 6,6 vezes mais freqüentes que os casos extremamente graves, sem diferenças entre os grupos por fatores de risco epidemiológicos.

The paper addresses the epidemiologic data of the death of pigs during the period of 2002 to 2009 following the ingestion of botulinum neurotoxin type C. This neurotoxin was present in food residues originating from restaurant and hotel kitchens, stored in barrels without shelter from the sun and administered in a collective trough without prior thermal treatment. Animals which died at different ages showed clinical signs of botulism characterized by flaccid paralysis, weight loss, anorexia, weakness, lack of coordination, locomotion difficulties with the evolution of lateral recumbency with involuntary urination and defecation. No alterations were observed at postmortem and histological examination. The bioassay with serum neutralization in mice was carried out on samples of intestinal contents from pigs affected and revealed the presence of large quantities of botulinum toxin type C.

O inventário florístico de um fragmento de floresta semidecídua foi conduzido durante o período de maio de 1996 a abril de 1998 em um hectare de floresta localizado na região central da Reserva de Santa Genebra (22º49'45" S e 47º06'33" W) a 580-610 m de altitude. Foram identificadas 201 espécies, distribuídas em 57 famílias e 147 gêneros. Fabaceae e Rubiaceae (18 espécies), Myrtaceae (14 spp.), Rutaceae (11 spp.), Solanaceae e Sapindaceae (nove spp.), Bignoniaceae, Meliaceae e Euphorbiaceae (oito spp.), Malvaceae (sete spp.) foram as famílias mais ricas. Cerca de 70% das espécies foram classificadas como secundárias tardias e secundárias tardias de sub-bosque. A comparação de espécies arbóreas com 25 fragmentos do Estado de São Paulo e Norte do Paraná mostraram que a flora da reserva é mais similar às florestas da região de Campinas. Embora a floresta apresente áreas perturbadas, existem manchas de vegetação relativamente maduras sendo esta área essencial para a conservação da biodiversidade.

This study was carried out to evaluate the antioxidant capacity of the agro-industrial waste from acerola. Hydroacetone, hydroethanolic, and hydromethanolic extracts were obtained using the sequential extraction process, and they were screened for their free radical DPPH• (1,1-diphenyl-2-picrilhidrazil) and ABTS•+ (2,2'-azino-bis-(3-etilbenzotiazolin 6-sulfonic acid) scavenging activity and their effect on the linoleic acid peroxidation by the ferric thiocyanate method. Soybean oil with the addition of the extracts (200 ppm) was submitted to Schaal oven test (60 °C, 28 days), in which the samples were analyzed for peroxide value and conjugated dienes. Hydroethanolic and hydromethanolic extracts exhibited good DPPH scavenging activity (low value of EC50 and TEC50 and high value of AE), good ABTS scavenging capacity (1445.1 and 1145.5 µMol TEAC.g-1, respectively), and high percentage inhibition of peroxidation of linoleic acid (96.12 and 91.84%, respectively) and showed the ability to retard the formation of peroxides and conjugated dienes.

The aim of this work was to perform the microbiological and physicochemical characterization of surimi made from waste of piramutaba filleting. The results of physicochemical characterization of the waste and surimi were: moisture (76.37 and 79.11%), total lipids (5.35 and 0.74%), proteins (14.92 and 10.79%), ash (3.03 and 2.35%), pH (6.9 and 7.4), caloric value (109.15 and 77.86 kcal.g-1), and water activity (both 0.98), respectively. The results of the levels of total volatile bases were 7.29 mgN/100-1 g (waste) and 7.01% carbohydrate (surimi). The values of total lipids and proteins were reduced during the preparation of surimi, probably due to successive washes during the processing. Waste and surimi were examined microbiologically and are in compliance with required parameters. The results show a loss of red (a* parameter) and yellow (b* parameter) color. On the other hand, the L* parameter (lightness) increased after the processing of surimi. It can be concluded that piramutaba waste can be used for surimi preparation and as a source of nutrients for human consumption, providing an alternative use of these wastes avoiding their disposal polluting the environment.

There is a trend towards the use of novel technologies nowadays, mainly focused on biological processes, for recycling and the efficient utilization of organic residues that can be metabolized by different microorganisms as a source of energy. In the present study the isolation of bacterial strains from six different agro-industrial by-products and waste was performed with the objective of evaluating their hydrolytic capacities and suitability for use in bioconversion of specific substrates. The 34 isolated strains were screened in specific culture media for the production of various hydrolytic enzymes (lipase, protease, cellulase, and amylase). It was found that 28 strains exhibited proteolytic activity, 18 had lipolytic activity, 13 had caseinolytic activity, 15 had amylolytic activity, and 11 strains exhibited cellulolytic activity. The strains that showed the highest hydrolytic capacities with biotechnological potential were selected, characterized genotipically, and identified as Bacillus, Serratia, Enterococcus, Klebsiella, Stenotrophomonas, Lactococcus, and Escherichia genera. It was concluded that the strain isolates have a high potential for use in the bioconversion of agro-industrial waste, both as a pure culture and as a microbial consortium.

Acerola is a fruit that can be consumed in the form of juice and pulp. However, during its processing, a large amount of waste is generated (seed and bagasse). Adding value to these by-products is of great interest, since their use can enrich foods with nutrients and fiber. In this study, we performed phytochemical screening, determined the proximate and mineral composition, bioactive compounds and the technological functional properties of acerola seed flour and acerola bagasse flour. Seeds were dried in a ventilated oven at ± 45 °C and the bagasse was lyophilized. Samples were ground, stored in flasks protected from light. Phytochemical screening revealed metabolites of nutritional and pharmacological interest and no potentially toxic substances in the flours. Seed flour and bagasse flour showed high levels (g 100 g- 1 of dry matter - DM) of soluble fiber: 4.76 and 8.74; insoluble fiber: 75.76 and 28.58, and phenolic compounds: 4.73 and 10.82, respectively. The flours also showed high absorption of water, oil and emulsion stability, presenting potential for inclusion in meat products and bakery products.

Potato pulp waste (PPW) drying was investigated under different experimental conditions (temperatures from 50 to 70 °C and air flow from 0.06 to 0.092 m³ m- 2 s- 1) as a possible way to recover the waste generated by potato chip industries and to select the best-fit model to the experimental results of PPW drying. As a criterion to evaluate the fitting of mathematical models, a method based on the sum of the scores assigned to the four evaluated statistical parameters was used: regression coefficient (R²), relative mean error P (%), root mean square error (RMSE), and reduced chi-square (χ²). The results revealed that temperature and air velocity are important parameters to reduce PPW drying time. The models Midilli and Diffusion had the lowest sum values, i.e., with the best fit to the drying data, satisfactorily representing the drying kinetics of PPW.

The fish industry generates high volume of waste from fish oil that can have the extraction of its lipids used as nutraceuticals and foods. The objective of this study was to produce unsaturated fatty acids from industrialized fish oil by means of a differentiated hydrolysis process. The samples used were crude fish oil obtained from Campestre industry and characterized through physical-chemical parameters, according to AOCS: acidity, peroxide, saponification, iodine and percentage of free fatty acids and also obtained the fatty acid profile through derivatization method for gas chromatography. The results obtained for the oleochemical indices for refined oil were similar to the data found on the literature. The content of polyunsaturated fatty acids (PUFA) was found of 32,78%, with 9,12% of docosahexaenoic (DHA) and 10,36% of eicosapentaenoic (EPA), regarding monounsaturated fatty acids (MUFA) content was of 30,59% in the hydrolyzed fish oil in relation to refined (20,06%). Thus, it can be concluded that the hydrolysis process used for oils from fish-waste was satisfactory on the production of absolute yield of lipids in the process and significant preservation on the percentages of EPA and DHA, interesting on the production of nutraceuticals and nutrition of aquatic animals, including shrimp in captivity.

Abstract Biodegradable films blends made of safflower oil nutraceutical capsules waste corn starch (20:4, 30:4, 40:4 and 50:4) were prepared. The objective of this study was to evaluate the influence of addition of different concentrations of safflower oil nutraceutical capsule waste in the mechanical properties (tensile strength, elongation at break, Young’s modulus) and thickness of corn starch films. A decrease in tensile strength and Young’s modulus and an increase in elongation at break were observed with the increase in the content of the nutraceutical capsule waste. The results showed that the blends of safflower oil capsules waste-corn starch films demonstrated promising characteristics to form biodegradable films with different mechanical characteristics.

Quality of municipal public spending on primary education in Brazil. The focus of this paper was to analyze the relationship between municipal public education spending and students' academic achievement, evaluated according to IDEB (Index of Basic Education Development) of 2005. The following databases were used: School Census 2005, Brazil Exam (mathematics evaluation applied to students from fourth grade of elementary school) and Finance of Brazil (FINBRA). A multilevel model was estimated and the results suggest that simply increasing the percentage of municipal expenditures on education or the percentage of spending on primary education in relation to municipal expenditures on education do not automatically guarantee improvements in the quality of education.
