Effects of filter choice in GT3X accelerometer assessments of free-living activity (Publications)
PURPOSE: Actigraph accelerometers are widely used devices to objectively assess physical activity. The GT3X version has two filter options to be selected prior to data assessment (normal and low frequ
Predictors of methacholine responsiveness in a general population (Publications)
OBJECTIVE: Methacholine responsiveness is an end point widely used in epidemiologic studies of asthma. This study aims to quantify the relative importance of different predictors of responsiveness suc
Glutathione S-transferase polymorphisms, passive smoking, obesity, and heart rate variability in nonsmokers (Publications)
BACKGROUND: Disturbances of heart rate variability (HRV) may represent one pathway by which second-hand smoke (SHS) and air pollutants affect cardiovascular morbidity and mortality. The mechanisms are
Ten-year follow-up of cluster-based asthma phenotypes in adults: a pooled analysis of three cohorts (Publications)
Rationale: The temporal stability of adult asthma phenotypes identified using clustering methods has never been addressed. Longitudinal cluster-based methods may provide novel insights in the study of
Genome-wide association studies identify CHRNA5/3 and HTR4 in the development of airflow obstruction (Publications)
RATIONALE: Genome-wide association studies (GWAS) have identified loci influencing lung function, but fewer genes influencing chronic obstructive pulmonary disease (COPD) are known. OBJECTIVES: Perfor
Heart rate variability and sleep-related breathing disorders in the general population (Publications)
Obstructive sleep apnea seems to have an important influence on the autonomic nervous system. In this study, we assessed the relations of sleep apnea-related parameters with 24-hour heart rate variabi
Air pollution and atherosclerosis: a cross-sectional analysis of four European cohort studies in the ESCAPE study (Publications)
BACKGROUND: In four European cohorts, we investigated the cross-sectional association between long-term exposure to air pollution and intima-media thickness of the common carotid artery (CIMT), a pre-
Assessing seasonal variations and age patterns in mortality during the first year of life in Tanzania (Publications)
Lack of birth and death registries in most of developing countries, particularly those in sub-Saharan Africa led to the establishment of Demographic Surveillance Systems (DSS) sites which monitor larg
International workshop on insecticide resistance in vectors of arboviruses, December 2016, Rio de Janeiro, Brazil (Publications)
Vector-borne diseases transmitted by insect vectors such as mosquitoes occur in over 100 countries and affect almost half of the world's population. Dengue is currently the most prevalent arboviral di
