1. Estado nutricional e qualidade de vida de escolares de 7 a 10 anos de idade de municípios da Região Metropolitana de Campinas / Nutritional status and quality of life for students aged 7 to 10 years old of cities in the Metropolitan Region of Campinas
The aim was to investigate nutritional status (NS) and quality of life (QOL) of students in municipal elementary schools (MES) of cities with different socio-economic characteristics of the Metropolitan Region of Campinas. We have studied 1162 boys and 1104 girls enrolled in MES from 1st to 4th grades, from Artur Nogueira (SP) and Vinhedo (SP). The search wa

4. APPLICATION OF PRINCIPAL COMPONENTS AND MULTIPLE LOGISTIC REGRESSION IN A GEOGRAPHICAL INFORMATION SYSTEM FOR PREDICTION AND DIGITAL SOIL MAPPING / APLICAÇÃO DE COMPONENTES PRINCIPAIS E REGRESSÕES LOGÍSTICAS MÚLTIPLAS EM SISTEMA DE INFORMAÇÕES GEOGRÁFICAS PARA A PREDIÇÃO E O MAPEAMENTO DIGITAL DE SOLOS
Social demands on soil information have grown dramatically, meanwhile the soil surveys are seldom carried out in the country. Digital soil mapping techniques can be applied to infer the spatial distribution of soil from existing soil maps or from reference areas, extrapolating this information to areas not mapped. The purpose of this study was to apply in a

5. Using pegylated interferon alfa-2b and ribavirin to treat chronic hepatitis patients infected with hepatitis c virus genotype 1: are nonresponders and relapsers different populations?
The combination of pegylated interferon (PEG-INF) and ribavirin is currently the best treatment for chronic hepatitis C, providing a sustained virological response (SVR) in 54%-63% of patients. In patients infected with hepatitis C virus (HCV) genotype 1, the SVR rate is 42%-52%. To evaluate the treatment efficacy of this drug combination, we conducted an op

6. Using Cases and Parents to Study Multiplicative Gene-by-Environment Interaction
With case-parent triads, one can estimate genotype relative risks by measuring the apparent overtransmission of susceptibility genotypes from parents to affected offspring. Results obtained using such designs, properly analyzed, resist both bias due to population structure and bias due to self-selection. Most diseases are not purely genetic, and environmenta

7. Maternal Catecholamine Levels in Midpregnancy and Risk of Preterm Delivery
Associations between stress hormones and preterm delivery have not been fully explored. In this study, pregnant women enrolled from 52 clinics in 5 Michigan communities (1998–2004) provided urine samples for 3 days (waking and bedtime) during midpregnancy. Urinary catecholamine levels (epinephrine, norepinephrine, and dopamine) were measured in a subcohort

8. Placental Vascular Pathology Findings and Pathways to Preterm Delivery
The authors examined the associations between placental vascular findings and preterm delivery in 1,053 subcohort women (239 preterm, 814 term) from a Michigan pregnancy cohort study (1998–2004). Twenty-nine placental vascular variables from microscopic examinations were grouped into 5 constructs: 3 maternal constructs—obstructive lesions (MV-O), bleedin
