Splenic autotransplantation seems to be the only alternative for preservation of splenic tissue after total splenectomy. This work was carried out to analyze the morphologic regeneration of autotransplanted splenic tissue in Wistar rats and to determine the bacterial phagocytic function of their macrophages. We utilized an experimental model including young(More)
PURPOSE To evaluate the alterations on plasmatic lipids levels among rats submitted to total splenectomy isolated or combined with splenic autotransplant receiving standard chow during the postoperative period. METHODS Thirty Wistar rats were divided into three groups: control (C)-- sham-operated, total splenectomy--isolated (TS) or combined with splenic(More)
Improvement (defined broadly as purposive efforts to secure positive change) has become an increasingly important activity and field of inquiry within healthcare. This article offers an overview of possible methods for the study of improvement interventions. The choice of available designs is wide, but debates continue about how far improvement efforts can(More)
Wistar rats submitted to isolated total splenectomy or total splenectomy combined with splenic autotransplantation were inoculated with 99mtechnetium-labeled Escherichia coli. Measurement of isotope uptake in the organs of the mononuclear phagocytic system showed a greater bacterial bloodstream clearance in rats with splenic autotransplantation. Although(More)
OBJECTIVE To assess the feasibility of HIV rapid testing for pregnant women at maternity hospital admission and of subsequent interventions to reduce perinatal HIV transmission. METHODS Study based on a convenience sample of women unaware of their HIV serostatus when they were admitted to delivery in public maternity hospitals in Rio de Janeiro and Porto(More)
BACKGROUND Hip fractures in the elderly are common and associated with considerable mortality and disability. Although well known in industrialized countries, the factors associated with mortality after hip fractures are not reported frequently in developing countries and little is known regarding risk factors in Latin America. QUESTIONS/PURPOSE We(More)
OBJECTIVE To assess rates of offering and uptake of HIV testing and their predictors among women who attended prenatal care. METHODS A population-based cross-sectional study was conducted among postpartum women (N=2,234) who attended at least one prenatal care visit in 12 cities. Independent and probabilistic samples were selected in the cities studied.(More)
Despite the excellent results obtained with hormone therapy, the long treatment period and the side effects associated with its use make patient adherence difficult. Moreover, certain aspects of health care can mitigate or exacerbate non-adherence. This study aimed to identify the factors associated with adherence to hormone therapy for breast cancer, with(More)
OBJECTIVES The objective of this study was to assess the association between oral health-related quality of life (OHRQoL), measured through the Child-OIDP, and demographic characteristics, self-reported oral problems, and clinical oral health measures, among 11- to 12-year-old school children in the city of Rio de Janeiro, Brazil. METHODS A(More)
CONTEXT International studies have shown a large variation in the utilization patterns of interventions, in acute myocardial infarction. OBJECTIVE To analyze utilization patterns of pharmacological interventions in acute myocardial infarction and their corresponding effects on hospital mortality. DESIGN Cross-sectional study.
