Impact of Neighborhood Disadvantage on Preventive and Acute Care Utilization in Sickle Cell Disease.

Background: Individuals with sickle cell disease (SCD) experience significant healthcare disparities; however, there is little known on the impact of psychosocial stressors and neighborhood disadvantage on preventive and acute care utilization in this population.

Procedure: A retrospective data collection was performed for all patients cared for at a comprehensive pediatric sickle cell center in the Midwest who had also completed the Psychosocial Assessment Tool (PAT), a validated caregiver-reported measurement of family psychosocial risk, from September 2021 through December 2022. Patient age, payor, primary language, frequency of acute and missed preventive care visits, as well as Area Deprivation Index (ADI) and Childhood Opportunity Index (COI) scores were collected for 256 patients.

Neutrophilic inflammation during lung development disrupts elastin assembly and predisposes adult mice to COPD.

Emerging evidence indicates that early life events can increase the risk for developing chronic obstructive pulmonary disease (COPD). Using an inducible transgenic mouse model for NF-κB activation in the airway epithelium, we found that a brief period of inflammation during the saccular stage (P3-P5) but not alveolar stage (P10-P12) of lung development disrupted elastic fiber assembly, resulting in permanent reduction in lung function and development of a COPD-like lung phenotype that progressed through 24 months of age. Neutrophil depletion prevented disruption of elastic fiber assembly and restored normal lung development.
