Epidemiology and risk stratification of young infants presenting to the emergency department with hypothermia.

Objective: Hypothermic infants are presumed to be at high risk for a serious bacterial infection (SBI) or herpes simplex virus (HSV) infection. In contrast to febrile infants, the emergency department (ED) management of hypothermic infants is variable in the absence of consensus guidelines, potentially resulting in low-value care and missed diagnoses. We investigated the diagnostic workup conducted for hypothermic infants in our academic pediatric ED, the incidence of SBI and HSV infection, and risk factors associated with infection.

Neighborhood greenspace and neighborhood income associated with white matter grade worsening: Cardiovascular Health Study.

Introduction: We examined whether a combined measure of neighborhood greenspace and neighborhood median income was associated with white matter hyperintensity (WMH) and ventricle size changes.

Methods: The sample included 1260 cognitively normal ≥ 65-year-olds with two magnetic resonance images (MRI; ≈ 5 years apart). WMH and ventricular size were graded from 0 (least) to 9 (most) abnormal (worsening = increase of ≥1 grade from initial to follow-up MRI scans).
