Methods Fifty-four patients with C1N among 729 patients who received PCI were retrospectively studied and the related risk factors, cardiovascular events and preventive strategy were analyzed. Results C1N was strongly associated with pre-procedure chronic renal failure, diabetes mellitus and large-dose contrast. The incidence of cardiac mortality and major adverse cardiac events 1 year after PCI in CIN group was higher than that in group without CIN. Conclusion Chronic renal failure, diabetes mellitus and dosage of contrast agent were three independent risk factors of CIN. CIN could affect the patients＇ prognosis. A well overall perioperative management of CAD patients following PCI, especially hydration therapy, is the most important strategy for prevention of CIN.展开更多

Secondary prevention of GI malignancies through early detection and treatment of cancer-precursor/premalignant lesions, therefore, is recognized as an effective cancer prevention strategy. In order to efficiently detect these lesions, systemic application of screening tests (surveillance) is needed. However, most of the currently used non-invasive screening tests for GI malignancies (for example, serum markers such as alpha-fetoprotein for hepatocellular carcinoma, and fecal occult blood test, for colon cancer) are only modestly effective necessitating the use of highly invasive endoscopy-based procedures, such as esophagogastroduodenoscopy and colonoscopy for screening purposes. Even for hepatocellular carcinoma where non-invasive imaging (ultrasonography) has become a standard screening tool, the need for repeated liver biopsies of suspicious liver nodules for histopathological confirmation can't be avoided. The invasive nature and high-cost associated with these screening tools hinders implementation of GI cancer screening programs. Moreover, only a small fraction of general population is truly predisposed to developing GI malignancies, and indeed needs surveillance. To spare the average-risk individuals from superfluous invasive procedures and achieve an economically viable model of cancer prevention, it's important to identify cohorts in general population that are at substantially high risk of developing GI malignancies (riskstratification), and select suitable screening tests for surveillance in these cohorts. We herein provide a brief overview of such high-risk cohorts for different GI malignancies, and the screening strategies that have commonly been employed for surveillance purpose in them.展开更多
