Abstract

The adult with congenital heart disease (CHD) is at risk of developing atherosclerotic cardiovascular disease (ASCVD). We performed a cross-sectional study to describe established ASCVD risk factors and estimate 10-year and lifetime risk of ASCVD in adults over age 18 with CHD of moderate or great complexity using 3 validated risk assessment tools-the Framingham Study Cardiovascular Disease Risk Assessment, the Reynolds Risk Score, and the ASCVD Risk Estimator. We obtained extensive clinical and survey data on 178 enrolled patients, with average age 37.1 12.6years, 51% men. At least 1 modifiable ASCVD risk factor was present in 70%; the 2 most common were overweight/obesity (53%) and systemic hypertension (24%). Laboratory data were available in 103 of the 178 patients. Abnormal levels of glycated hemoglobin, high-sensitivity C-reactive protein, and high-density lipoprotein were each found in around 30% of patients. The 10-year ASCVD predicted risk using all 3 tools was relatively low (i.e., at least 90% of patients <10% risk), yet the median estimated lifetime risk was 36%. In conclusion, ASCVD risk factors are prevalent in adults with CHD. The risk estimation tools suggest that this population is particularly vulnerable to ASCVD with aging and should undergo guideline-based screening and management of modifiable risk factors.

Abstract

Over the last 50 years, improved surgical techniques and progressive medical management have allowed patients with complete or dextro-transposition of the great arteries (D-TGA) to survive into adulthood. Older adult patients underwent an atrial switch procedure (Mustard or Senning operation), whereas the younger cohort of patients with TGA has undergone the arterial switch operation (ASO). The Mustard/Senning maintains the right ventricle as the systemic ventricle, whereas the more recently adopted ASO attempts to restore normal physiologic and anatomic relationships. Neither operation is without consequence. Neither is without consequence and require long term follow up.

Abstract

In the absence of specific high-affinity agonists and antagonists, it has been difficult to define the target genes and biological responses attributable to many of the orphan nuclear receptors (ONRs). Indeed, it appears that many members of this receptor superfamily are not regulated by classical small molecules but rather their activity is controlled by interacting cofactors. Motivated by this finding, we have developed an approach to genetically isolate specific receptor-cofactor pairs in cells, allowing us to define the biological responses attributable to each complex. This is accomplished by using combinatorial peptide phage display to engineer the receptor interacting domain of each cofactor such that it interacts selectively with one nuclear receptor. In this study, we describe the customization of PGC-1alpha and its use to study the biology of the estrogen-related receptor alpha (ERRalpha) in cultured liver cells.
