Hippocampal volume in patients with asthma: Results from the Dallas Heart Study.

Introduction: Asthma is associated with an increased risk of mild cognitive impairment and dementia. Depression and oral corticosteroid use are associated with atrophy of the hippocampus and are common in asthma. However, minimal neuroimaging data are available in asthma patients.

Cardiovascular Risk Factors Associated with Smaller Brain Volumes in Regions Identified as Early Predictors of Cognitive Decline.

Purpose: To determine in a large multiethnic cohort the cardiovascular and genetic risk factors associated with smaller volume in the hippocampus, precuneus, and posterior cingulate, and their association with preclinical deficits in cognitive performance in patients younger and older than 50 years.

Materials And Methods: The institutional review board approved the study and all participants provided written informed consent. Eligible for this study were 1629 participants (700 men and 929 women; mean age, 50.

New approaches to lymphatic imaging.

Accurate imaging of the lymphatic system can aid in cancer staging, optimize surgical procedures to reduce lymphedema, and may one day be a means of delivering intralymphatic therapy. The Sentinel Lymph Node (SLN) concept has been pivotal in driving new imaging techniques. Metastasis to a SLN is a critical indicator of advanced disease.
