Are parent perceptions of neighborhood stressors associated with general health and child respiratory health among low-income , urban families?
More negative perceptions tended to be associated with higher risk of undesirable outcomes, adding to evidence that the social environment contributes to health and supporting research on stress' health impact among disadvantaged populations. Interventions must address not only traditional "environmental" factors, but also individuals' reactions to stress and attempt to mitigate effects of stressors while structural solutions to health inequities are sought.
The present study has provided data supporting normal Treg cell frequency in A-SLE and I-SLE as well as increased frequency of Teff cells in A-SLE. This scenario reflects a Treg/Teff ratio imbalance that may favour the inflammatory phenotype of the disease. In addition, the increased frequency of T cells with putative intermediate phenotypes may be compatible with a highly dynamic immune system in SLE.
