Modificações introduzidas pelos treinamentos cardiopulmonar e neuromuscular nos níveis séricos basais de fatores de crescimento insulina símile i (igf-1), cortisol, autonomia funcional e qualidade de vida de mulheres idosas

Changes introduced by cardiopulmonar and neuromuscular training on basal serum insulin-like grow factor-1 (IGF-1) and cortisol levels, functional autonomy and quality of life in elderly women The aim of this study was to compare the effects of strength and aerobic training on basal serum IGF-1 and Cortisol levels, functional autonomy (FA) and quality of life (QoL) in elderly women after 12 weeks of training. The subjects were submitted the strength training (75-85% 1-RM) with weight exercises (SG; n=12; age=66.08 ± 3,37 years; BMI=26,77 ± 3,72 kg/m2), aerobic training with aquatic exercises (AG; n=13; age=68,69 ± 4,70 years; BMI=29,19 ± 2,96 kg/m2) and control group (CG; n=10; age=68,80 ± 5,41 years; BMI=29,70 ± 2,82 kg/m2). Fasting blood was analyzed to measure basal IGF-1 and cortisol levels by chemiluminescence method. The t-Student test showed increased IGF-1 in the SG (p<0.05) for intragroup comparison. The Repeated-measure ANOVA presented increased IGF-1 (p<0.05) in the SG compared to the other two groups. There were no differences in cortisol levels. All the FA tests (GDLAM autonomy protocol) presented decreased significant in the time marked in seconds to the SG. The same results were found in the AG, except in the rise from a sitting position test. The autonomy index presented significant improvements (p<0.05) in the SG related to the AG and CG and in the AG to the CG. The SG showed increased QoL (p<0.05) (by WHOQOL-Old questionnaire) in the facet 1 (sensorial functioning) and facet 5 (death and dying). Thus, the SG obtained positive changes on IGF-1 and FA levels when compared to the AG. This suggests that strength training can indicated to decrease the effects of ageing.

O Fundef e o Fundeb como política de financiamento para a valorização do magistério: efeitos na carreira e na remuneração dos professores da rede pública estadual de ensino do RN

Le présent étude analyse les effets de la politique de financement de l éducation de base, par les Fonds contables, Fundef et Fundeb, et sa proposition de valorisation de l enseignement, en considerant les dimensions de la carrière et de la rémunération des professeurs de l éducation publique de l état du Rio Grande do Norte, entre les années de 1996 et 2000. Pour comprendre les contraintes de l évaluation des politiques publiques, en cherchant aussi les contribution en Marx (1996) selon qui « le concret est concret » et que la dialétique du concret peut appuyer pour la tentative de capter le fenomène étudié. On a utilisé encore le référentiel bibliographique relatif au financement de l éducation et la valorisation de l enseignement à partir de la littérature reférente aux dimensions de l objet (Fundef et Fundeb) et (carrière et rémuneration). Dans la recherche documental, au-delà des législations, directrices nationales et locales pertinentes, se sont utilisés des donnés référents aux ressources, disponibles à la Finbra, Trésor National, SIOPE/RN, INEP/MEC, des informations du résumé de la feuille et feuille de payement du Secrétariat d État, de l Éducation et de la Culture (SEEC) et 289 bulletins de salaire de 21 professeurs. On a réalisé interview semi structurée avec une quantité de 9 professeurs, reférent à la carrière, et un questionaire appliqué à 12 professeurs relatif à la remuneration. On considère que sur les résultats reférents aux indicateurs éducationnel, dans la période Fundef il y a eu une réduction des inscriptions aux écoles de l état comme aussi aux fonctions des professeurs de l Enseignement Fondamental, et cela correspond à 37%. À partir de la vigence du Fondebe (2007 - 2010) ces indicateurs ont équalisé. Pendant toute la période, 1996 et 2010 il y a eu une augmentation des inscriptions de 119,03%, et aussi aux fonctions des professeurs de 77,44%. Par rapport aux informations de financement, on a constaté que, du minimum exigé (60%) sur l aplication des fonds à la rémuneration de l enseignant, on applique pour la période des deux fonds, plus que le minimum exigé, c est-à-dire de 83,29% à 98,89% des fonds. Les effets des fonds sur la carrière des 9 professeurs n ont pas été satisfactoires, si l on considère la promotion et la progression. Au cas de la promotion des 9 de ces professeurs, un seul a évolué son niveau (les titres) mais a, au même temps, rétroagit dans sa progression. Pour la progression des 9 professeurs, 8 d entre eux ont sa progression retardée, ce qui correspond à entre 2 et 5 classes, et ce qui provoque un préjudice qui varie entre 10% à 45% sur sa remunération. La différence d une classe à l autre correspond à 5% de son salaire. On évalue que les avantages financières contribuent pour la remunération avec un pourcentage plus élevé que son salaire, ce qui diminuent pendant lo Fundeb. Par rapport à la remunération un professeur de 24 ans de service avec formation, n arrive même pas à gagner 2 salaires minimums. Le professeur de 30 ans de service, maître, reçoit un salaire, en 2010, qui correspond a moins de 3 salaires minimums, c est-à-dire, une proportion de 2,82 et une remuneration qui correspond à un peu plus que 3 salaires minimums, c est-à-dire, une proportion de 3,66. L enseignement n est pas très favorisé si on le met face à d autres profession qui ont aussi l exigence de formation supérieure, ce qui provoque un effet négatif pour voir l enseignement comme profession. À propos des effets sur la rémuneration, on conclue qu il y a eu une amélioration mais encore insufisante, surtout si l on compare au Salaire Minimum annuel. On évalue que les fonds Fundef et Fundeb n ont pas été capables de promouvoir la valorisation de l enseignement dans le contexte de carrière et rémuneration. On observe quelques résultats négatif dans la politique de fonds, une fois qu il y aurait en avoir avec l incapacité de tel politique en promouvoir la dite valorisation de l enseignement, ce qui est une des causes, le financement avec des restriction budgétaire

Ganho genético com base no tamanho efetivo populacional de progênies de seringueira

O objetivo deste trabalho foi estimar os ganhos genéticos de um teste de progênies de seringueira para a produção de borracha seca e, com base no maior tamanho efetivo populacional e maior ganho genético, obter os melhores indivíduos. Foram utilizadas 30 progênies de meios-irmãos, provenientes de sementes de polinização mista - alogamia e autogamia - de testes clonais no Estado de São Paulo. Utilizou-se o delineamento experimental de blocos ao acaso, com 30 tratamentos (progênies), 3 repetições e parcelas lineares de 10 plantas, em um espaçamento de 3x3 m, o que totalizou 900 plantas úteis. Aos três anos, o perímetro, a 50 cm do solo (PA50), e a produção de borracha seca (PBS) foram avaliadas por meio do teste precoce de produção Hamaker Morris-Mann (HMM). As variáveis foram analisadas pelo método de modelo linear misto, via procedimento REML/BLUP, em progênies com sistema reprodutivo misto e taxa de autofecundação de 22%. A identificação dos 20 melhores indivíduos quanto à PBS e ao PA50 proporcionou ganho genético de 67,96 e 16,48%, respectivamente, e um coeficiente de endogamia de aproximadamente 2,82%. O teste de progênies proporciona produção de sementes com melhor valor genético, grande variabilidade e baixa endogamia

Metabolic syndrome and its associated risk factors in Brazilian postmenopausal women

Objective To evaluate the prevalence of metabolic syndrome (MetS) and its associated risk factors in Brazilian postmenopausal women.Methods In this cross-sectional study, a total of 368 postmenopausal women, aged 40-75 years, seeking health care at a public outpatient center in Southeastern Brazil, were included. According to the US National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III) guidelines, MetS was diagnosed in subjects with three or more of the following: waist circumference >= 88 cm, blood pressure >= 130/85 mHg, triglycerides >= 150 mg/dl, high density lipoprotein cholesterol <50 mg/dl and glucose >= 110 mg/dl. Data on past medical history, tobacco use, anthropometric indicators, and values of C-reactive protein (CRP) were collected. Multivariate analysis, using a logistic regression model (odds ratio, OR) was used to evaluate the influence of various simultaneous MetS risk factors.Results The prevalence of having at least three, four and five MetS diagnostic criteria were met in 39.6%, 16.8% and 3.8% of the cases, respectively. The most prevalent risk factor was abdominal obesity, affecting 62.5% of women. The risk of MetS increased with a personal history of diabetes (OR 5.95, 95% confidence interval (CI) 2.82-12.54), hypertension (OR 4.52, 95% CI 2.89-7.08), cardiovascular disease (OR 2.16, 95% CI 1.18-3.94) and high CRP (>1 mg/dl) (OR 3.35, 95% CI 1.65-6.79). Plasma CRP levels increased with the number of MetS components present. Age, time since menopause and smoking had no influence, while hormone therapy reduced MetS risk (OR 0.64, 95% CI 0.42-0.97).Conclusion Metabolic syndrome was highly prevalent among Brazilian postmenopausal women seeking gynecologic health care. Abdominal obesity, diabetes, hypertension and high CRP were strong MetS predictors and hormone therapy appeared to play a protective role for this condition.

Transfusão de eritrócitos em crianças internadas em unidade de terapia intensiva pediátrica

JUSTIFICATIVA E OBJETIVOS: As indicações de transfusão de eritrócitos não estão bem estabelecidas em crianças gravemente enfermas. O objetivo deste estudo foi descrever a prática da transfusão de eritrócitos na UTI Pediátrica do Hospital de Clínicas da Universidade Estadual Paulista (HC-UNESP). MÉTODO: Estudo retrospectivo observacional realizado durante o ano de 2003. RESULTADOS: Setenta e cinco pacientes receberam transfusão, havendo registro de 105 indicações. Mais da metade dos pacientes (53,3%) tinha menos que um ano de idade. Taquipnéia (75,2%), palidez (65,7%) e hipotensão (51,4%) foram os registros mais freqüentemente observados antes da transfusão. Além disso, a gasometria evidenciou acidose metabólica (68,08%) e hipoxemia (63,8%). Dos 93 registros de valores de hemoglobina (Hb), 54 (58,1%) estavam entre 7 e 10 g/dL e dos 90 registros de hematócrito (Ht) observou-se que 66 (73,3%) apresentavam valores entre 21% e 30%. As principais indicações de transfusão foram anemia em 75 crianças (71,4%) e sangramento ativo em 26 (24,7%). O valor médio de Hb antes da transfusão foi de 7,82 ± 2,82 g/dL. Sete transfusões foram indicadas para pacientes com valores de Hb > 10 g/dL, crianças estas em pós-operatório imediato de intervenção cirúrgica cardíaca e casos de choque séptico. CONCLUSÕES: A transfusão de eritrócitos vem sendo utilizada criteriosamente, com indicações restritivas (Hb entre 7 e 10 g/dL). Nem sempre há anotação dos valores de Hb imediatamente antes da transfusão. A partir deste estudo, foi elaborado um protocolo de indicação de transfusão na unidade.

Predicting MAOD Using Only a Supramaximal Exhaustive Test

The objective of this study was to propose an alternative method (MAOD(ALT)) to estimate the maximal accumulated oxygen deficit (MAOD) using only one supramaximal exhaustive test. Nine participants performed the following tests: (a) a maximal incremental exercise test, (b) six submaximal constant workload tests, and (c) a supramaximal constant workload test. Traditional MAOD was determined by calculating the difference between predicted O(2) demand and accumulated O(2) uptake during the supramaximal test. MAOD(ALT) was established by summing the fast component of excess post-exercise oxygen consumption and the O(2) equivalent for energy provided by blood lactate accumulation, both of which were measured during the supramaximal test. There was no significant difference between MAOD (2.82 +/- 0.45 L) and MAOD(ALT) (2.77 +/- 0.37 L) (p = 0.60). The correlation between MAOD and MAOD(ALT) was also high (r = 0.78; p = 0.014). These data indicate that the MAOD(ALT) can be used to estimate the MAOD.

Crescimento do caranguejo de água doce, Dilocarcinus pagei Stimpson (Crustacea, Brachyura, Trichodactylidae)

A biologia de caranguejos de água doce tem sido pouco enfocada na literatura carcinológica, especialmente em relação ao crescimento das espécies da família Trichodactylidae. Este estudo visa determinar as curvas de crescimento em tamanho e peso, bem como a longevidade e a idade na muda pubertária dos caranguejos de água doce Dilocarcinus pagei Stimpson, 1861. As amostras foram obtidas mensalmente na Represa Municipal de São José do Rio Preto (São Paulo), de outubro/1994 a setembro/1996. Os indivíduos tiveram o sexo determinado, sendo também mensurados (LC = largura do cefalotórax) e pesados (PE = peso úmido). O crescimento dos indivíduos foi determinado pelo método de distribuição dos exemplares em classes de tamanho, sendo utilizado o programa FiSAT para a determinação das curvas através do ajuste não linear dos dados pelo modelo de Bertalanffy. Foram analisados 962 exemplares (534 machos e 428 fêmeas) e as curvas de crescimento em tamanho foram expressas pelas equações LC Machos = 61,7[1-e-0,97(t+0,041)] e LC Fêmeas = 57,1[1-e-1,41(t+0,031)], enquanto o crescimento em peso foi melhor representado por PE Machos = 65,2[1-e-0,97(t+0,041)]3,08 e PE Fêmeas = 44,9[1-e-1,41(t+0,031)]2,82. O tamanho assintótico dos machos (61,66 mm) foi pouco superior ao das fêmeas (57,09 mm), ocorrendo o inverso para a longevidade, estimada em 2,4 e 2,7 anos, respectivamente. O tamanho máximo estimado com base em 95% do tamanho assintótico foi de 58,6 mm para os machos e 54,2 mm para as fêmeas, valores muito próximos dos maiores tamanhos registrados na natureza para cada sexo (55,8 mm). A muda da puberdade dos machos ocorreu com idade superior à das fêmeas (tMachos = 1,2 anos e tFêmeas = 0,9 anos). Os resultados obtidos neste trabalho são inéditos na literatura carcinológica, sendo de grande valia no manejo populacional e preservação desta espécie, que vem sendo intensamente explorada e usada como isca na pesca esportiva.

Fissuras lábio-palatais: estudo caso-controle

Realizou-se um estudo caso-controle com o propósito de se detectar possíveis fatores de risco para o aparecimento de fissuras orais. Foram objeto de análise: local de moradia da mãe nos quatro primeiros meses de gestação, poluição, aplicação de pesticida/herbicida na lavoura, doenças dos pais, doenças da mãe nos quatro primeiros meses de gestação, ingestão medicamentosa nesse período, hereditariedade, tabagismo, consumo de bebida alcoólica e exposição a raio-X. Foram aplicados formulários às mães referentes aos 450 casos, sendo 354 portadores de fissuras labiais ou lábio-palatais e 96 de fissuras palatinas, e às mães referentes aos 450 controles. Empregou-se análise multivariada e as variáveis hereditariedade (RR=4,96), epilepsia na mãe (RR=2,39) e ingestão de anti-inflamatório (RR=2,59) foram consideradas fatores de risco para fissuras labiais ou lábio-palatais. As variáveis hereditariedade (RR=2,82) e poluição (RR=2,58) foram consideradas fatores de risco para fissuras palatinas.

Indirect determination of chloride and sulfate ions in alcohol fuel by capillary electrophoresis

A capillary zone electrophoresis method using indirect UV detection for the analysis of chloride and sulfate in alcohol fuel samples was developed. The anions were analyzed in less than 3 min using an electrolyte containing 10 mmol 1(-1) chromate and 0.75 mmol 1(-1) hexamethonium bromide (HMB) as electroosmotic flow modifier. Coefficients of variation were better than 0.6% for migration time (n = 10) and between 2.05 and 2.82% for peak area repeatabilities. Analytical curves of peak area versus concentration in the range of 0.065-0.65 mg kg(-1) for chloride and 0.25-4.0 mg kg(-1) for sulfate were linear with coefficients of correlation higher than 0.9996. The limits of detection for sulfate and chloride were 0.033 and 0.041 mg kg(-1), respectively. Recovery values ranged from 85 to 103%. The method was successfully applied for the quantification of sulfate and chloride in five alcohol fuel samples. The concentration of sulfate varied from 0.45 to 3.12 mg kg(-1). Chloride concentrations were below the method's LOD.

Temporal trends in incidence of Type 1 diabetes between 1986 and 2006 in Brazil

Background: Scarce information is available about the variation in the incidence of Type 1 diabetes in the Brazilian population in the last decades. Aim: The objective of this study was to assess the long-term trends (1986-2006) in the incidence of Type 1 diabetes in Bauru, São Paulo State, Brazil. Subjects and methods: The annual incidence of Type 1 diabetes (per 100,000 per yr) from 1986 to 2006 was determined in children yr of age, using the capture and recapture method. Results: A total of 176 cases were diagnosed in the study population. The overall incidence was 10.4/100,000 with a range of 2.82/100,000 in 1987 to 18.49/100,000 in 2002 representing a 6.56-fold increase within the same population. The estimated incidence, using the capture and recapture method varied from 2.82/100,000 per yr in 1987 to 27.20/100,000 per yr in 2002, representing a 9.6-fold variation. The global pattern of incidence variation was categorized as high (10-19.99/100,000 per yr), and very high (20/100,000 per yr) in 71.43% of the study-years. Incidence was slightly higher among females, Caucasians, children in the 5-9 yr of age range and belonging to lower socio-economic classes. Most diagnoses were established during the colder months and/or with higher pluviometric indexes. Conclusions: The incidence of Type 1 diabetes in children is increasing in Bauru, São Paulo State, Brazil, and the global pattern of incidence was classified as high or very high, mainly in the last 10 yr. All Brazilian regions should be involved in the study. (J. Endocrinol. Invest. 33: 373-377, 2010) (C)2010, Editrice Kurtis

Natural chromenes and chromene derivatives as potential anti-trypanosomal agents

The aim of the study was to investigate the anti-trypanocidal activities of natural chromene and chromene derivatives. Five chromenes were isolated from Piper gaudichaudianum and P. aduncum, and a further seven derivatives were prepared using standard reduction, methylation and acetylation procedures. These compounds were assayed in vitro against epimastigote forms of Trypanosoma cruzi, the causative agent of Chagas disease. The results showed that the most of the compounds, especially those possessing electron-donating groups as substituents on the aromatic ring, showed potent trypanocidal activity. The most active compound, [(2S)-methyl-2-methyl-8-(3″-methylbut-2″-enyl)-2- (4′-methylpent-3′-enyl)-2H-chromene-6-carboxylate], was almost four times more potent than benznidazole (the positive control) and showed an IC 50 of 2.82 μM. The results reveal that chromenes exhibit significant anti-trypanocidal activities and indicate that this class of natural product should be considered further in the development of new and more potent drugs for use in the treatment of Chagas disease. © 2008 Pharmaceutical Society of Japan.
