Performance evaluation of the Afias Igra-TB (IFN-gamma) test versus QuantiFeron®-TB gold plus (QFT®-Plus) Elisa in the Barrio Obrero hospital network, Asunción—Paraguay, 2025
Background: Tuberculosis infection affects an estimated one-quarter of the global population and represents a key target for TB elimination strategies. While interferon-gamma release assays (IGRAs) such as QuantiFERON-TB Gold Plus (QFT-Plus) are WHO-endorsed, they remain logistically complex in low-resource settings. This study evaluates the performance of the AFIAS IGRA-TB, a qualitative fluorescence immunoassay (FIA), compared to QFT-Plus in Pa…
Evaluation of diagnostic agreement between STANDARD E TB-Feron Elisa and TB-Feron FIA for tuberculosis infection in prison settings in Paraguay
Introduction Accurate diagnosis of tuberculosis (TB) infection is essential for TB control, particularly in high-risk populations. Interferon-gamma release assays (IGRAs) are widely used for TB infection screening. This study assesses the diagnostic agreement between the STANDARDTM F TB-Feron fluorescence immunoassay (FIA) and the WHO-approved STANDARD E TB-Feron ELISA in penitentiary settings in Paraguay. Methods A cross-sectional study was cond…
Integrated serological surveillance of communicable diseases in the Paraguayan Chaco, 2019
Objective. To establish baseline seroprevalence of soil-borne, waterborne, and foodborne diseases and to monitor diseases that are eliminated or on the path to elimination in the Paraguayan Chaco. Methods. A total of 1 100 school-age children (6–15 years) were tested in urban and rural schools selected for a cross-cutting population-based survey using a two-stage probabilistic sample design in the three departments of the Paraguayan Chaco. Blood …
Worldwide trends in underweight and obesity from 1990 to 2022
BACKGROUND: Underweight and obesity are associated with adverse health outcomes throughout the life course. We estimated the individual and combined prevalence of underweight or thinness and obesity, and their changes, from 1990 to 2022 for adults and school-aged children and adolescents in 200 countries and territories. METHODS: ). For school-aged children and adolescents, we report thinness (BMI 2 SD above the median). FINDINGS: From 1990 to 20…
Incarceration and TB
Epidemiology of Suicide Mortality in Paraguay from 2005 to 2019
Suicide is an important public health problem, fundamentally affecting the younger population and responding to multiple biological, psychological, and social causes. The objective of this study was to characterize changes in suicide mortality, suicide methods, and years of potential life lost from 2005 to 2019 in Paraguay. This observational, descriptive study used data from the Vital Statistics Information Subsystem of the Ministry of Public He…
Factores asociados al resultado de tratamiento no exitoso de pacientes con tuberculosis sensible en Paraguay
Objetivo. Determinar los factores asociados con el tratamiento no exitoso en pacientes diagnosticados con tuberculosis (TB) sensible en Paraguay. Métodos. Estudio de cohorte retrospectivo, con datos recolectados del programa nacional entre enero de 2016 y marzo de 2017. Se definió tratamiento no exitoso como pacientes que se perdieron en el seguimiento, fracasaron en el tratamiento o fallecieron. Los factores asociados con tratamiento no exitoso …
Carga de enfermedad atribuible al uso del tabaco en Paraguay y potencial impacto sanitario y económico del aumento del precio a través de impuestos
The cost and the burden of disease associated to tobacco consumption is high in the health system in Paraguay. An increase in cigarette price through taxes could have significant health benefits and could offset health costs in part
