Clinical exome sequencing vs. usual care for hereditary colorectal cancer diagnosis: a pilot comparative effectiveness study.
The purpose of this study was to evaluate clinical exome sequencing (CES) compared to usual care (UC) in the diagnostic work-up of inherited colorectal cancer/polyposis (CRCP) in a randomized controlled trial (RCT). The investigators indicate that their results suggest that CES provides similar clinical benefits to multi-gene panels in the diagnosis of hereditary CRCP.

Comparison of comorbidity scores in predicting surgical outcomes.
The purpose of this study was to compare diagnosis-based and prescription-based comorbidity scores for predicting surgical outcomes. It concluded that the Centers for Medicare and Medicaid Services-Hierarchical Condition Categories had superior performance in predicting surgical outcomes. Prescription-based scores, alone or in addition to diagnosis-based scores, were not better than any diagnosis-based scoring system.

Diagnostic performance of cardiac magnetic resonance imaging and echocardiography in evaluation of cardiac and paracardiac masses.
The researchers evaluated the predictive value of echocardiography and cardiac magnetic resonance (CMR) imaging parameters to identify tumors and malignancy and to provide histopathologic diagnosis of cardiac masses. They found that CMR identified 6 masses missed on transthoracic echocardiography (4 of which were outside the heart) and provided significantly more correct histopathologic diagnoses compared to echocardiography (77 percent vs 43 percent).
