El Niño Southern Oscillation and vegetation dynamics as predictors of dengue fever cases in Costa Rica
(2009-03-04)Dengue fever (DF) and dengue hemorrhagic fever (DHF) are growing health concerns throughout Latin America and the Caribbean. This study focuses on Costa Rica, which experienced over 100 000 cases of DF/DHF from 2003 to ... -
The effects of human movement on the persistence of vector-borne diseases
(2009-06)With the recent resurgence of vector-borne diseases due to urbanization and development there is an urgent need to understand the dynamics of vector-borne diseases in rapidly changing urban environments. For example, many ... -
Developing a cooperative multicenter study in Latin America: Lessons learned from the Latin American Study of Nutrition and Health Project
(2017)This report examines the challenges of conducting a multicenter, cross-sectional study of coun- tries with diverse cultures, and shares the lessons learned. The Latin American Study of Nutrition and Health (ELANS) was used ... -
Urban structure and dengue incidence in Puntarenas, Costa Rica
(2009-07-15)Dengue is currently the most important arboviral disease globally and is usually associated with built environments in tropical areas. Remotely sensed information can facilitate the study of urban mosquito-borne diseases ... -
Participatory risk mapping of malaria vector exposure in northern South America using environmental and population data
(2014-03-01)Malaria elimination remains a major public health challenge in many tropical regions, including large areas of northern South America. In this study, we present a new high spatial resolution (90 × 90 m) risk map for Colombia ... -
Latin American Study of Nutrition and Health (ELANS): rationale and study design
(2016-01)Abstract Background: Obesity is growing at an alarming rate in Latin America. Lifestyle behaviours such as physical activity and dietary intake have been largely associated with obesity in many countries; however studies ... -
Standardization of the Food Composition Database Used in the Latin American Nutrition and Health Study (ELANS)
(2015-09)Between-country comparisons of estimated dietary intake are particularly prone to error when different food composition tables are used. The objective of this study was to describe our procedures and rationale for the ... -
Relevance of the plasminogen activation system in the pathogenesis and progression of gastric cancer
(2018-03)Gastric cancer is ranked as the third death-causing cancer and one of the most incident malignancies worldwide. Although Helicobacter pylori is the most well-established risk factor for the development of this neoplasm, ... -
Total and Added Sugar Intake: Assessment in Eight Latin American Countries
(2018-03)Non-communicable diseases are growing at an alarming rate in Latin America. We assessed total and added sugar intake in Argentina, Brazil, Chile, Colombia, Costa Rica, Ecuador, Peru, and Venezuela, to verify the adequacy ... -
Two Groups of Cocirculating, Epidemic Clostridiodes difficile Strains Microdiversify through Different Mechanisms
(2018-03)Clostridiodes difficile strains from the NAPCR1/ST54 and NAP1/ST01 types have caused outbreaks despite of their notable differences in genome diversity. By comparing whole genome sequences of 32 NAPCR1/ST54 isolates and ... -
Isolates of Clostridium perfringens recovered from Costa Rican patients with antibiotic-associated diarrhoea are mostly enterotoxin-negative and susceptible to first-choice antimicrobials
(2008-03)To assess the prevalence of enterotoxigenic Clostridium perfringens among adults suffering from antibiotic-associated diarrhoea in a Costa Rican hospital, faecal samples were analysed from 104 patients by a cultivation ... -
Demonstration of antibiotic-induced tolerance development in tropical agroecosystems through physiological profiling of sediment microbial communities
(2014-01)Agricultural use of antibiotics differs quantitatively and qualitatively in tropical and temperate countries. To gain insight into the nature and magnitude of physiological adaptations prompted by these drugs in microbial ... -
Phenotypic identification of over 1000 isolates of anaerobic bacteria recovered between 1999 and 2008 in a major Costa Rican hospital
(2011-07)Because of limitations in infrastructure, the aetiology of infections caused by anaerobic bacteria is seldom determined in clinical laboratories of developing countries. This study reports on the identification of 1010 ... -
