NCT01366534
This study will evaluate whether administration of two investigational malaria vaccines (257049 and Ad35.CS.01 vaccines) combined in one immunization schedule increases protection against malaria infection as compared to protection induced by the 257049 vaccine alone. The study will also evaluate the safety and the immune response to the new combination of the two experimental malaria vaccines.
NCT03560830
Gulf War Illness (GWI) veterans were divided into 2 pathophysiological groups based on their orthostatic tachycardia responses after submaximal exercise. Two thirds had normal increases of 10 to 15 beats per minute between recumbent and standing both before and after exercise. These were termed the Stress Test Originated Phantom Perception (STOPP) phenotype. In contrast, one third had increases in heart rate of more than 30 beats per minute indicating that exercise induced postural tachycardia; there were the Stress Test Activated Reversible Tachycardia (START) group. This study aimed to confirm the original findings of Rayhan (2013).
NCT00890136
This project aims to characterize the independent effect of domestic endotoxin exposure on health status, as well as pulmonary and systemic inflammation, in former smokers with COPD. Positive findings from this study would be clinically relevant, as they would provide evidence to support aggressive reduction of ongoing endotoxin exposure in patients with COPD. The investigators also hope to make a methodological advance in the field of endotoxin exposure assessment by elucidating whether settled dust and/or airborne endotoxin measurements are the more relevant exposure of interest in epidemiological studies of respiratory disease. To fulfill the specific aims, the investigators will conduct a longitudinal study, including 75 former smokers with COPD. All subjects will have indoor air monitoring, in-home settled dust collections, home inspections as well as assessments of health status, quality of life (QOL), lung function and pulmonary and systemic inflammation.
