The role of cockroach allergy and exposure to cockroach allergen in causing morbidity among inner-city children with asthma

Abstract: Background It has been hypothesized that asthma-related health problems are most severe among children in inner-city areas who are allergic to a specific allergen and also exposed to high levels of that allergen in bedroom dust. Methods From November 1992 through October 1993, we recruited 476 children with asthma (age, four to nine years) from eight inner-city areas in the United States. Immediate hypersensitivity to cockroach, house-dust-mite, and cat allergens was measured by skin testing. We then measured major allergens of cockroach (Bla g 1), dust mites (Der p 1 and Der f 1), and cat dander (Fel d 1) in household dust using monoclonal-antibody–based enzyme-linked immunosorbent assays. High levels of exposure were defined according to proposed thresholds for causing disease. Data on morbidity due to asthma were collected at base line and over a one-year period. Results Of the children, 36.8 percent were allergic to cockroach allergen, 34.9 percent to dust-mite allergen, and 22.7 percent to cat allerg...

The neuro-symphony of stress

Abstract: The impact of stress on brain function is increasingly recognized. Various substances are released in response to stress and can influence distinct neuronal circuits, but the functional advantages of having such a diversity of stress mediators remain unclear. Individual neurotransmitter, neuropeptide and steroid stress mediators have specific spatial and temporal niches, but these niches also overlap. In addition, the effects of individual mediators on neuronal function and plasticity are integrated, and emerging evidence suggests that there is crosstalk between them. Together, this results in the stress instruments producing an orchestrated 'symphony' that enables fine-tuned responses to diverse challenges.

The Crucible Within: Ethnic Identity, Self-Esteem, and Segmented Assimilation Among Children of Immigrants

Abstract: Focusing on the formation of ethnic self-identities during adolescence, this paper examines the psychosocial adaptation of children of immigrants from Asia, Latin America and the Caribbean. The data are drawn from the CILS survey carried out in the San Diego and Miami metropolitan areas of over 5,000 children of immigrants attending the 8th and 9th grades in local schools. The sample is evenly split by gender and nativity (half are U.S.-born, half foreign-born). The results show major differences in their patterns of ethnic self-identification, both between and within groups from diverse national origins. Instead of a uniform assimilative path, we found segmented paths to identity formation. Detailed social portraits are sketched for each ethnic identity type. Multivariate analyses then explore the determinants of assimilative and dissimilative ethnic self-identities, and of other aspects of psychosocial adaptation such as self-esteem, depressive affect, and parent-child conflict, controlling for gender, socioeconomic status, and national origin. The theoretical and practical implications of these results – especially the effects of acculturation, discrimination, location and ethnic density of schools, parental socialization and family context, upon the psychosocial adaptation of children of recent immigrants to the United States – are discussed.
