“Pulse pressure (PP) is an independent predictor of myocardial infarction, mainly above 50 years of age. In subjects with preserved ejection fraction (EF), aortic PP predicts the severity of coronary atherosclerosis. Comparable findings in subjects with reduced EF have not been evaluated. In 1337 subjects with severe coronary ischaemic disease, intra-aortic and brachial blood pressures were measured together with EF and coronary angiography to
evaluate cardiac function, the presence of coronary stenosis and/or occlusions or calcifications. The presence (odds ratio +/- 95% CI) of coronary calcification was marginally but not significantly associated (P=0.06) to increased selleck chemical aortic PP (1.32 (0.97-1.80)), whereas that of coronary occlusion was significantly associated (P<0.01) with decreased aortic PP (0.62 (0.42-0.91)), even after adjustment to EF LGX818 solubility dmso and heart rate. Increased aortic PP did not correlate with stenosis number. No comparable predictive value was observed using intra-aortic or non-invasive brachial systolic blood pressure (SBP) or diastolic blood pressure (DBP). In high cardiovascular risk populations, even in the presence of reduced EF and high heart rate, intra-aortic
PP, but not SBP or DBP, is a significant predictor of coronary occlusions and possibly calcifications, but not stenosis. Journal of Human Hypertension (2010) 24, 51-57; doi: 10.1038/jhh.2009.36; 3-Methyladenine mw published online 14 May 2009″
“Cetuximab, a monoclonal antibody targeting epidermal growth factor receptor, has proven to be efficient in the treatment of metastatic colorectal cancer. We made a prospective study of the efficacy and toxicities of cetuximab-combination first-line (FOLFOX4) versus second/third-line (FOLFIRI) chemotherapy in 98 KRAS wildtype patients who had metastatic colorectal cancer. Wild-type KRAS had been identified by direct sequencing. Associations between clinical response/progression-free survival/overall survival/toxicities and cetuximab-combination chemotherapy
timing were evaluated. The overall response rate was significantly higher for first-line treatment than for second/third-line treatment (relative risk = 1.707, 95% confidence interval = 1.121-2.598). Both progression-free survival and overall survival indicated significantly longer survival of first-line treatment than second/third-line treatment patients. This study is a validation of a molecular analysis of KRAS wild-type status for the prediction of response to cetuximab-combination chemotherapy for metastatic colorectal cancer patients; its predictive role was less prominent in the second/third-line than in the first-line treatment patients.”
