Fatty acids in mature breast milk from low socioeconomic levels of Venezuelan women: influence of temperature and time of storage. Breast milk is the main food in infants from birth until six months old. It is important to know if precarious life conditions could limit some nutrients in mother's milk.

Rotavirus mortality confirmed by etiologic identification in Venezuelan children with diarrhea.

Background: Hospital-based studies to determine the etiology of deaths from diarrhea are scarce. In this study, we specifically analyzed deaths due to rotavirus to assess the rotavirus impact on diarrhea mortality.

Methods: To determine the rotavirus proportion contributing to mortality due to diarrhea, we analyzed data obtained from a hospital-based mortality surveillance, conducted over 7 years, in the Ciudad Hospitalaria Dr.

Epidemiologic and clinical characteristics of rotavirus disease during five years of surveillance in Venezuela.

Background: To effectively introduce a rotavirus vaccine in developing countries, it is necessary to estimate the burden of rotavirus disease. Therefore we examined the epidemiologic and clinical features of rotavirus diarrhea in children younger than 5 years of age in Carabobo State and extrapolated these results to the rest of Venezuela.

Methods: From January 1, 1998 to December 31, 2002, we conducted surveillance for rotavirus diarrhea in all children younger than 5 years of age at the Ciudad Hospitalaria Dr Enrique Tejera, in Valencia (Carabobo).

Intussusception-associated hospitalization among Venezuelan infants during 1998 through 2001: anticipating rotavirus vaccines.

Background: The first licensed rotavirus vaccine was withdrawn from use in the United States because of a low risk of intussusception. Consequently tests of new rotavirus vaccines will require some baseline knowledge of the rates and treatment of intussusception in countries where these vaccines will be tested. Therefore the objective of this study was to assess hospitalization rates and describe the epidemiologic and clinical characteristics of intussusception in Carabobo, Venezuela.
