Towards emplaced understandings of risk: How caregivers of children with asthma identify and manage asthma-related risk across different places

In the United States, pediatric asthma is distributed geographically across lines of racialized segregation. We draw on emplacement, or the theory that embodied experiences and the material world are mutually informed, to situate such geographic trends within the narratives of 41 caregivers of children with asthma. Results suggest that caregivers identified and managed asthma-related risk with regard to the relational and structural conditions of three categories of locations: (1) houses, (2) neighborhoods, and (3) schools and other childhood institutions. Within each type of location, caregivers used emplaced knowledge and emplaced caregiving tactics to respond to asthma-related risk. Based on our findings, we identify critical intervention topics that are consistent with families' everyday lived experiences of place.

Detrimental Impact of Microbiota-Accessible Carbohydrate-Deprived Diet on Gut and Immune Homeostasis: An Overview

Dietary fibers are non-digestible polysaccharides functionally known as microbiota-accessible carbohydrates (MACs), present in inadequate amounts in the Western diet. MACs are a main source of energy for gut bacteria so the abundance and variety of MACs can modulate gut microbial composition and function. This, in turn, impacts host immunity and health. In preclinical studies, MAC-deprived diet and disruption of gut homeostasis aggravate the development of inflammatory diseases, such as allergies, infections, and autoimmune diseases. The present review provides a synopsis on the impact of a low-MAC diet on gut homeostasis or, more specifically, on gut microbiota, gut epithelium, and immune cells.
