Objective To evaluate the intra-and interobserver reliability of assessment of three-dimensional power Intra-and interobserver reliability was assessed by intraclass correlation coefficients (ICC).Results Ninety-five pregnancies were included in the analysis. All three placental 3D-PD indices showed only weak to moderate reliability (ICC < 0.66 and ICC < 0.48, respectively

ObjectiveTo evaluate the effectiveness and safety of polyunsaturated fatty acids for the treatment of the premenstrual syndrome (PMS) using a graded symptom scale and to assess the effect of this treatment on basal plasma levels of prolactin and total cholesterol.MethodsA randomized, double-blind, placebo-controlled study was conducted with 120 women with PMS divided into three groups and treated with 1 or 2 grams of the medication or placebo. Symptoms were recorded over a 6-month period using the Prospective Record of the Impact and Severity of Menstruation (PRISM) calendar. Total cholesterol and prolactin levels were measured. Analysis of variance (ANOVA), Pearson's chi-square test, Wilcoxon's nonparametric signed-rank test for paired samples and the Mann-Whitney nonparametric test for independent samples were used in the statistical analysis.ResultsThere were no differences in age, marital status, schooling or ethnicity between the groups. In the group treated with 1 gram of the medication, a significant reduction was found when the median PRISM score recorded in the luteal phase at baseline (99) was compared with the median score recorded in the 3rd month (58) and in the 6th month of evaluation (35). In the 2-gram group, these differences were even more significant (baseline score: 98; 3rd month: 48; 6th month: 28). In the placebo group, there was a significant reduction at the 3rd but not at the 6th month (baseline: 96.5; 3rd month: 63.5; 6th month: 62). The difference between the phases of the menstrual cycle was greater in the 2-gram group compared to the group treated with 1 gram of the medication. There were no statistically significant differences in prolactin or total cholesterol levels between baseline values and those recorded after six months of treatment.ConclusionThe difference between the groups using the medication and the placebo group with respect to the improvement in symptomatology appears to indicate the effectiveness of the drug. Improvement in symptoms was higher when the 2-gram dose was used. This medication was not associated with any changes in prolactin or total cholesterol levels in these women.

Aos gerentes de compras, compradores, pessoal de apoio e técnicos das montadoras pesquisadas pela receptividade e colaboração, pois de outro modo não teria sido possível concluir os estudos de caso.À minha esposa pelo estímulo, apoio e compreensão. RESUMONo decorrer dos anos 90, a função compras nas empresas do setor automotivo passou por uma significativa transformação. A área de compras, que estava tipicamente voltada para a atividade de aquisição, passou a fazer parte de um processo complexo e integrado, envolvendo, além da área de compras, outras áreas da organização (engenharia, qualidade, finanças, logística, marketing, entre outras) que exercem papel estratégico.Vários fatores contribuíram para essa transformação, destacando-se dentre eles: a influência das práticas da produção enxuta (lean production), as novas formas de relacionamento entre as empresas na cadeia de suprimentos, a evolução dos negócios pela Internet, o surgimento de fornecedores mais especializados em função dos avanços tecnológicos e a própria competição global, provocando uma reestruturação organizacional nas empresas.Neste cenário, o presente trabalho estuda a evolução da atividade de compras levando em conta a interdependência entre as dimensões produzir, comprar e fornecer, interdependência essa que, a partir de um determinado projeto de produto, afeta a forma como a área de compras se organiza e opera na empresa e junto à cadeia de suprimentos.Conceitos como sede de projeto, sede de produção, produção modular, desverticalização produtiva, just in time, entre outros, são tratados no presente trabalho como uma espécie de pano de fundo para a nova configuração de compras, analisada em duas montadoras, localizadas no ABC Paulista, que centralizam as compras de materiais produtivos para as demais plantas localizadas no Brasil.Como contribuição científica, o presente trabalho procura mostrar a configuração de compras de empresas que adotam práticas modernas tanto na gestão de suprimentos como no relacionamento com o fornecedor, analisando a nova forma de atuação de compras, cujas atividades vão além das negociações típicas de preço e prazo e requerem o aprimoramento do perfil e das qualificações dos compradores. ABSTRACTDuring the 1990's, sourcing in companies of the automotive sector underwent a major transformation process. The purchasing area, which until then had been typically geared to buying, became part of a complex and integrated process involving other areas besides purchasing (such as engineering, quality, finance and logistics, among others), and which have a strategic role in the organization.Several factors have contributed to this transformation, outstanding among them: the influence of lean production practices, the new types of relationships among companies in the supply chain, the e-business boom, the presence of more specialized suppliers due to technological advancements and to global competition itself. All of these aspects have caused an organizational restructuring in the companies.Ser against this scenario, this w...

A great percentage of individuals with cholesterol levels above those recommended to prevent coronary artery disease was found.

Objective To evaluate and compare the intraobserver and interobserver reliability and agreement for the biparietal diameter (BPD), abdominal circumference (AC), femur length (FL) and estimated fetal weight (EFW) obtained by two-dimensional ultrasound (2D-US) and threedimensional ultrasound (3D-US).
