Comparison between 100-g glucose tolerance test and two other screening tests for gestational diabetes: combined fasting glucose with risk factors and 50-g glucose tolerance test

CONTEXTO E OBJETIVO: A falta de consenso sobre os protocolos de rastreamento e diagnóstico do diabetes gestacional, associada às dificuldades na realização do teste oral simplificado do diabete gestacional (o teste de tolerância a 100 g de glicose, considerado padrão-ouro) justificam a comparação com alternativas. O objetivo deste trabalho é comparar o teste padrão-ouro a dois testes de rastreamento: associação de glicemia de jejum e fatores de risco (GJ + FR) e o teste oral simplificado de tolerância a 50 g de glicose (TTG 50 g), com o teste de tolerância a 100 g de glicose (TTG 100 g). TIPO DE ESTUDO E LOCAL: Estudo de coorte longitudinal, prospectivo, realizado no Serviço de Ginecologia e Obstetrícia do Hospital Universitário da Universidade Federal de Mato Grosso do Sul. MÉTODOS: 341 gestantes foram submetidas aos três testes. Calcularam-se os índices de sensibilidade (S), especificidade (E), valores preditivos (VPP e VPN), razões de probabilidade (RPP e RPN) e resultados falsos (FP e FN), positivos e negativos da associação GJ + FR e do TTG 50 g em relação ao TTG 100 g. Compararam-se as médias das glicemias de uma hora pós-sobrecarga (1hPS) com 50 e 100 g. Na análise estatística, empregou-se o teste t de Student, com limite de significância de 5%. RESULTADOS: A associação GJ + FR encaminhou mais gestantes (53,9%) para a confirmação diagnóstica que o TTG 50 g (14,4%). Os dois testes foram equivalentes nos índices de S (86,4 e 76,9%), VPN (98,7 e 98,9%), RPN (0,3 e 0,27) e FN (15,4 e 23,1%). As médias das glicemias 1hPS foram semelhantes, 106,8 mg/dl para o TTG 50 g e 107,5 mg/dl para o TTG 100 g. CONCLUSÕES: Os resultados da eficiência diagnóstica associados à simplicidade, praticabilidade e custo referendaram a associação GJ + FR como o mais adequado para o rastreamento. A equivalência das glicemias de 1hPS permitiram a proposição de um novo protocolo de rastreamento e diagnóstico do diabete gestacional, com menores custo e desconforto.

Hydroxyurea in the sickle cell anemia: toxicity and effectiveness

Objective: to evaluate the use of hydroxyurea with regard to effectiveness and toxicity in people with sickle cell anemia. Method: this is a retrospective descriptive study, developed with 57 medical records of patients with sickle cell anemia, treated at the University Hospital Center of Campo Grande (Mato Grosso do Sul, Brazil), from 1993 to 2005. Inclusion criteria: electrophoresis of hemoglobin in medical record; regular use of drugs, for an average of 196 weeks; dosage; and hematological analyses before starting treatment. Exclusion criteria: living with other hemoglobinopathies. The variables evaluated were: neutrophils count; platelets; leukocytes; hemoglobin; time using hydroxyurea; drug response to the optimal dosage; and number and type of episodes of hospitalization. The research protocol was approved by the Ethics Committee of Universidade Federal de Mato Grosso do Sul, under the Protocol 645. Results: of the 57 medical records, 3 cases were evaluated. Comparing the hematological values, according to Portaria 872, enacted on 11/12/2002, it was found that: cases A, B, and C present an use of hydroxyurea (500 mg/day) for four years, with an average of 196 weeks. Case A, female, decreased painful episodes and frequency of hospitalization, keeping hematological values with no toxicity. In Case B, female, there was one hospitalization due to pain crises and important hemolysis. It stood out, in case C, male, neutropenia with hematological values < 2,000/mm3 . Conclusion: in the cases analyzed, we observed a drop in the number of hospitalizations with the decrease in painful crises from three to one a year, and there was no toxicity with regard to the dosage and time using hydroxyurea, in all three cases. For more comprehensive results, one suggests further study on this therapy with significant samples of this clientele.

Anemia and hemoglobinopathies in pregnant women attended in a public hospital

Objectives: to identify the demographic profile and frequency of anemia and hemoglobinopathies, as a basis for future implementation of actions aimed at pregnant women in the public health domain. Method: this is a cross-sectional study developed with pregnant women attended in a university hospital at Mato Grosso do Sul, Brazil. Blood samples were collected for the erythrogram analysis for detection of anemia and selective and specific tests for abnormal hemoglobin. The patients regarded as indigenous and mentally ill, as well as inmates, were excluded from the research, as they represent a vulnerable population which needs a cohort different from that of the sample. For data collection, a particular questionnaire was used. The research was approved by the Ethics Committee of Universidade Federal de Mato Grosso do Sul (UFMS), under the Protocol 873/2006. Results: of the 215 pregnant women under study, 20% were adolescents; 36.3% had incomplete primary education; 53.0% were non-Caucasian; 43.3% were from Campo Grande, Mato Grosso do Sul, Brazil; and 21.1% were of European descent. 17.7% had some type of anemia and, in the evaluation of hemoglobinopathies, 4.7% of patients were detected with some abnormal hemoglobin, with the following frequencies: 3.3% with HbAS; 0.9% with HbAC; and 0.5% with intermediate β-thalassemia. Conclusion: the frequencies of anemia and hemoglobinopathy found in these pregnant women showed the importance of early diagnosis, revealing indicators able to provide a basis for preventive and assistance actions for adequate clinical monitoring, reducing maternal and neonatal morbimortality in the public health services. Descriptors: pregnant women; anemia; hemoglobinopathies; public health; nursing.

Monarquia e República nas crônicas machadianas

This article aims to analyze the significant social and political aspects of the transition from the Parliamentary Constitutional Monarchy to Federal and Presidential Republic, according to the literary work of the writer from Rio de Janeiro Joaquim Maria Machado de Assis (1839-1908). Some of these aspects appeared in Machadian chronicles entitled Balas de Estalo, published in the daily newspaper Gazeta News between 1883 and 1887. These chronicles were signed by Lelio, one of the nicknames of Machado de Assis.

O ringue escolar: as meninas no tatame

Whereas acts of violence in the school environment reflect cultural changes and social developments experienced by contemporary society, an important aspect to be studied with regard to gender issues, specifically those related to the new role assumed by women in contemporary society. Thus, this project aims to analyze the relationship between gender and school violence from the investigation of the perception that students in a class of high school, a public school in the city of Rio Claro, have on the subject. In addition, we attempted to contextualize historically gender relations throughout history; identify which gender is the highest occurrence of fights, as well as list the reasons identified by students for violence in the school environment. The results showed that school violence committed by females is performed by the towering male. And that in a nutshell, the reasons identified for the occurrence of school violence are related to disrespect, prejudices, misunderstandings, emotional issues and conflicts occurring in everyday spot.

Fishes from Baía da Medalha, southern Pantanal, Brazil: A 20 years review

Located in the Pantanal of Miranda-Abobral, the Baía da Medalha is the largest pond close to the Base de Estudos do Pantanal of the Universidade Federal de Mato Grosso do Sul. The Baía da Medalha has been a study site for several didactic and scientific projects for years. Nevertheless, its fish fauna has never been inventoried. Based on data collected from the beginning of the 1990s up to 2011, we provide a list of fish species from the Baía da Medalha. A total of 97 species were recorded, corresponding to about 40% of the species stated for the Pantanal. Characiformes and Siluriformes were the most species-rich orders, being Characidae and Cichlidae the families with the highest number of species. Regional seasonal flood dynamics and the abundance of aquatic macrophytes may be associated with this high diversity. The representative richness found in this lagoon highlights the importance of such taxonomic surveys to preserve the diversity of aquatic habitats within the Pantanal ecosystem.

Molecular cloning and insecticidal effect of Inga laurina trypsin inhibitor on Diatraea saccharalis and Heliothis virescens

Native Inga laurina (Fabaceae) trypsin inhibitor (ILTI) was tested for anti-insect activity against Diatraea saccharalis and Heliothis virescens larvae. The addition of 0.1% ILTI to the diet of D. saccharalis did not alter larval survival but decreased larval weight by 51%. The H. virescens larvae that were fed a diet containing 0.5% ILTI showed an 84% decrease in weight. ILTI was not digested by the midgut proteinases of either species of larvae. The trypsin levels were reduced by 55.3% in the feces of D. saccharalis and increased by 24.1% in the feces of H. virescens. The trypsin activity in both species fed with ILTI was sensitive to the inhibitor, suggesting that no novel proteinase resistant to ILTI was induced. Additionally, ILTI exhibited inhibitory activity against the proteinases present in the larval midgut of different species of Lepidoptera. The organization of the ilti gene was elucidated by analyzing its corresponding genomic sequence. The recombinant ILTI protein (reILTI) was expressed and purified, and its efficacy was evaluated. Both native ILTI and reILTI exhibited a similar strong inhibitory effect on bovine trypsin activity. These results suggest that ILTI presents insecticidal properties against both insects and may thus be a useful tool in the genetic engineering of plants. (c) 2012 Elsevier Inc. All rights reserved.
