BACKGROUND Decreased vagal activity after myocardial infarction results in reduced heart-rate variability and increased risk of death. To distinguish between vagal and sympathetic factors that affect heart-rate variability, we used a signal-processing algorithm to separately characterise deceleration and acceleration of heart rate. We postulated that(More)
BACKGROUND Identification of high-risk patients after acute myocardial infarction is essential for successful prophylactic therapy. The predictive accuracy of currently used risk predictors is modest even when several factors are combined. Thus, establishment of a new powerful method for risk prediction independent of the available stratifiers is of(More)
OBJECTIVE We examined the prognostic impact of lymph node ratio (relation of tumor-infiltrated to resected lymph nodes) in comparison to the pN category and other prognostic factors in patients with colorectal cancer. SUMMARY BACKGROUND DATA Although the high prognostic impact of lymph node metastases and the total number of lymph nodes to be resected are(More)
Evidence has accumulated that invasion and metastasis in solid tumors require the action of tumor-associated proteases, which promote the dissolution of the surrounding tumor matrix and the basement membranes. The serine protease urokinase-type plasminogen activator (uPA), which is elevated in solid tumors, appears to play a key role in these processes. We(More)
PURPOSE Maintenance of telomeres through reactivation of telomerase is a prerequisite for tumors to preserve their ability to proliferate. The purpose of this study was to evaluate telomere length and human telomerase reverse transcriptase (hTERT) expression as markers for progression and prognosis of colorectal carcinoma. PATIENTS AND METHODS Telomere(More)
BACKGROUND Drug-eluting stents are highly effective in reducing the rate of in-stent restenosis. It is not known whether there are differences in the effectiveness of currently approved drug-eluting stents in the high-risk subgroup of patients with diabetes mellitus. METHODS We enrolled 250 patients with diabetes and coronary artery disease: 125 were(More)
PURPOSE A recent study presented first evidence that a single nucleotide polymorphism (SNP) at codon 388 of fibroblast growth factor receptor 4 (FGFR4) gene, causing a transmembrane domain missense mutation (Gly388Arg), is associated with disease outcome in node-positive breast cancer. This article addresses the clinical relevance of this SNP, FGFR4(More)
BACKGROUND A work force based case-control study of lung cancer was performed in non-silicotic subjects exposed to crystalline silica to investigate the association between silica dust and lung cancer excluding the influence of silicosis. METHODS Two hundred and forty seven patients with lung cancer and 795 control subjects were enrolled, all of whom had(More)
BACKGROUND The clinical benefit of coronary-artery stenting performed in conjunction with coronary angioplasty is limited by the risk of thrombotic occlusion of the stent as well as hemorrhagic and vascular complications of intensive anticoagulation. We compared antiplatelet therapy with conventional anticoagulant therapy with respect to clinical outcomes(More)
CONTEXT Placement of sirolimus-eluting stents or paclitaxel-eluting stents has emerged as the predominant percutaneous treatment strategy in patients with coronary artery disease (CAD). Whether there are any differences in efficacy and safety between these 2 drug-eluting stents is unclear. OBJECTIVE To compare outcomes of sirolimus-eluting and(More)
