Understanding the structure-activity relationship and performance of highly active novel ATRP catalysts.

Copper bromide complexes based on a series of substituted guanidine-quinolinyl and -pyridinyl ligands are reported. The ligand systems were chosen based on the large variation with regard to their flexibility in the backbone, different guanidine moieties and influence by electron density donating groups. Relationships between the molecular structures and spectroscopic and electronic properties are described.

(Bio)Ethics and Primary Health Care: preliminary study on Family Clinics in the city of Rio de Janeiro, Brazil.

The Family Health Strategy (FHS) started out as the Family Health Program (FHP) in 1994, and has since has been re-thought and re-worked in Brazil as the primary rationale for reorganizing Primary Healthcare (PHC). Transforming the hegemonic PHC into FHS has resulted in many changes in how healthcare is provided, which have impacted different areas. For example, matters of (bio)ethics must still be elucidated.

Maternal mortality and accessibility to health services by means of transit-network estimated traveled distances.

This study analyzed the relationship between maternal mortality and variables related to the use of health services (especially residence-hospital traveled distances estimated through transit networks). Deaths were identified for Rio de Janeiro and adjacent cities, from 2000 to 2002, and were matched by age and socio-economic level to birth admissions without maternal deaths (1 case to 3 controls). The variables used were: type of hospital (general × specialized maternity services), number of hospital beds, nature of hospital ownership (public × private-associated), main admission diagnostic, residence-hospital distance, age, income, and education.

Geographic accessibility to obstetric care and maternal mortality in a large metropolitan area of Brazil.

Objective: To assess maternal mortality and its association with accessibility to obstetric care in the metropolitan region of Rio de Janeiro, Brazil.

Methods: Maternal mortality was assessed from 2 national databases, one administrative and the other designed for epidemiologic purposes. Distances traveled from residence to hospital via the transit network were calculated using a specialized information system.
