Hemodynamic response to primary prophylactic therapy with nonselective β-blockers is related to a reduction of first variceal bleeding risk in liver cirrhosis: a meta-analysis.

The current primary prophylaxis for esophageal variceal bleeding in cirrhotic patients consists of nonselective β-blocker (NSBB) therapy. However, only approximately half of the patients achieve a sufficient hemodynamic response to NSBB therapy. Clinical application of hemodynamic response monitoring is still under debate.

Genome-scale discovery of DNA-methylation biomarkers for blood-based detection of colorectal cancer.

Background: There is an increasing demand for accurate biomarkers for early non-invasive colorectal cancer detection. We employed a genome-scale marker discovery method to identify and verify candidate DNA methylation biomarkers for blood-based detection of colorectal cancer.

Methodology/principal Findings: We used DNA methylation data from 711 colorectal tumors, 53 matched adjacent-normal colonic tissue samples, 286 healthy blood samples and 4,201 tumor samples of 15 different cancer types.
