1. Performance of the CKD-EPI and MDRD equations for estimating glomerular filtration rate: a systematic review of Latin American studies
ABSTRACT BACKGROUND: The most-used equations for estimating the glomerular filtration rate (GFR) are the CKD Epidemiology Collaboration (CKD-EPI) and Modification of Diet in Renal Disease (MDRD) equations. However, it is unclear which of these shows better performance in Latin America. OBJECTIVE: To assess the performance of two equations for estimated GFR

2. Lipase and factor V (but not viral load) are prognostic factors for the evolution of severe yellow fever cases
BACKGROUND Despite a highly efficacious vaccine, yellow fever (YF) is still a major threat in developing countries and a cause of outbreaks. In 2018, the Brazilian state of São Paulo witnessed a new YF outbreak in areas where the virus has not been detected before. OBJECTIVE The aim is to describe the clinical and laboratorial characteristics of severe c

3. Respondent driven sampling (RDS) aplicado à populaÃÃo de homens que fazem sexo com homens no Brasil / Respondent driven sampling (RDS) applied to the population of men who have sex with men in Brazil
Os estimadores para parÃmetros populacionais em amostras coletadas pelo mÃtodo de amostragem Respondent Driven Sampling (RDS) sÃo sensÃveis à presenÃa de observaÃÃes ignoradas e tendem a subestimar os parÃmetros populacionais. A ausÃncia de um quadro de amostragem bem definido para a coleta de amostras em populaÃÃes consideradas escondidas e/ou d

4. A Bayesian approach to estimate the accuracy of "in-house" ELISA assay to measure rabies antibodies from compulsory vaccinated dogs and cattle
Rabies is a vaccine-preventable disease that causes acute encephalitis in mammals, and it is still a significant public health problem in numerous countries. Infected dogs represent the main vectors involved in human rabies. Additionally, cattle rearing close to geographic areas where vampire bats are found presents an important connection with rural epidemi

5. Epilepsia : prevalencia, caracteristicas epidemiologicas e lacuna de tratamento farmacologico / Epilepsy: prevalence, epidemiologic characteristics and pharmacological treatment gap
The worldwide prevalence of epilepsy is estimated at 10/1,000; however, access to treatment is variable. Many people go untreated, particularly in resource-poor countries. In Brazil, the epidemiologic studies never have approached the pharmacological treatment gap of epilepsy. The objectives of this study are: 1) to determine the epilepsy prevalence in two u

6. Calibração de examinadores para exame epidemiologico da carie dentaria : uma avaliação mediante diferentes limiares de diagnostico / Calibration of examiners for the epidemiological examination of dental caries, an evaluation under different diagnostic thresholds
This thesis, comprising 4 studies, aimed al evaluating the examiners calibration for the dental caries epidemiological survey, under different diagnostic thresholds. Methodology of the 4 studies: Eleven examiners, having experience in epidemiological surveys, were trained for the dental caries calibration. The inclusion criteria were based on those recommend

7. "Manifestações psicopatológicas não-psicóticas em uma amostra da comunidade chinesa da cidade de São Paulo" / Non-psychotic psychopathologic manifestations in a sample of the Chinese community in the city of São Paulo
Introdução: Os transtornos mentais que ocorrem na comunidade e em culturas diversas são temas de grande interesse frente às constantes transformações sociais no mundo. A mudança do foco de pesquisa para os transtornos freqüentes na comunidade possibilitou aperfeiçoamentos metodológicos e desenvolvimento de instrumentos sensíveis para a sua detecç

8. Sensitive Method for Detection of Human Herpesviruses 6 and 7 in Saliva Collected in Field Studies
To facilitate studies of the epidemiology and natural history of human herpesviruses 6 and 7 in infants, a practical method for collecting and quantifying the DNA of these viruses was developed. Saliva was collected using small strips of filter paper, and virus was detected using a real-time quantitative fluorescent-probe PCR assay. The sensitivity and speci

9. Sensitivities and Specificities of Spoligotyping and Mycobacterial Interspersed Repetitive Unit-Variable-Number Tandem Repeat Typing Methods for Studying Molecular Epidemiology of Tuberculosis
The development of PCR-based genotyping modalities (spoligotyping and mycobacterial interspersed repetitive unit-variable-number tandem repeat [MIRU-VNTR] typing) offers promise for real-time molecular epidemiological studies of tuberculosis (TB). However, the utility of these methods depends on their capacity to appropriately classify isolates. To determine

10. Molecular epidemiology of trachoma in a Gambian village.
The application of a diagnostic and genotyping technique based on the polymerase chain reaction (PCR) to the study of trachoma epidemiology in the Gambian village of Jali is reported. PCR based on the major outer membrane protein (MOMP) gene of Chlamydia trachomatis appears to be more sensitive than either isolation or antigen detection by enzyme immunoassay

11. pgi Genotyping Is a Surrogate for Serotyping of Encapsulated Haemophilus influenzae
Study of the epidemiology of invasive infections caused by encapsulated Haemophilus influenzae has been complicated by the poor sensitivity and specificity of the serologic assays used to identify specific capsular polysaccharides. The population structure of these bacteria is highly clonal, however, and serotype is highly correlated with other genetic chara

12. Comparison of PCR and Microscopy for Detection of Cryptosporidium parvum in Human Fecal Specimens: Clinical Trial
PCR technology offers alternatives to conventional diagnosis of Cryptosporidium for both clinical and environmental samples. We compared microscopic examination by a conventional acid-fast staining procedure with a recently developed PCR test that can not only detect Cryptosporidium but is also able to differentiate between what appear to be host-adapted gen
