Allergic rhinitis quality of life in urban children with asthma.

Background: Urban children with asthma and allergic rhinitis (AR) are at risk for experiencing worse AR-related quality of life (QOL). Although AR may be underdiagnosed and undertreated in urban minority children, research has not considered which illness-related indicators (eg, AR control) may contribute to AR QOL in this population.

Objective: To examine associations among AR control, asthma control, allergy symptoms, asthma symptoms, and AR QOL in a sample of 195 urban caregivers and their children with asthma (7-9 years of age) from African American, Latino, and non-Latino white backgrounds.

Asthma indicators and neighborhood and family stressors related to urban living in children.

Objective: To examine differences in asthma outcomes by levels of child-reported neighborhood and family stress related to urban living in a sample of children and their caregivers.

Methods: A total of 208 urban children with asthma, ages 6-12 and their primary caregivers from African-American, Latino, and non-Latino white backgrounds were included in this study.

Results: Children's report of higher levels of stress was related to poorer asthma control.

Cyanolide A, a glycosidic macrolide with potent Molluscicidal activity from the Papua New Guinea cyanobacterium Lyngbya bouillonii.

Over the last 50 years, molluscicides have played a critical role in the control of schistosomiasis transmission. Cyanolide A (2), isolated from extracts of a Papua New Guinea collection of Lyngbya bouillonii, is a new and highly potent molluscicidal agent against the snail vector Biomphalaria glabrata (LC(50) = 1.2 microM).
