PURPOSE It remains unclear if inflammation itself may induce cancer, if inflammation is a result of tumor growth, or a combination of both exists. The aim of this study was to examine whether C-reactive protein (CRP) levels and CRP gene variations were associated with an altered risk of colorectal, lung, breast, or prostate cancer. PATIENTS AND METHODS A(More)
BACKGROUND Angiotensin I-converting enzyme (ACE) inhibitors, angiotensin II antagonists, and the ACE insertion/deletion (I/D) gene polymorphism all influence serum angiotensin II action. Because angiotensin II levels have been associated with cancer, the objective of the current epidemiologic study was to investigate whether renin-angiotensin system(More)
PURPOSE To evaluate the extent, characteristics and determinants of adverse drug reaction (ADR)-related hospitalisations on a population-based level in 2003. METHODS We performed a cohort study in the Integrated Primary Care Information (IPCI) database, a general practitioners (GPs) research database with longitudinal data from electronic patient records(More)
S U M M A R Y The DEOS Mass Transport release 1 (DMT-1) model has been produced on the basis of intersatellite K-band ranging data acquired by the GRACE satellite mission. The functional model exploited in the data processing can be considered as a variant of the acceleration approach. Each element of the data vector is defined as a linear combination of(More)
BACKGROUND Primary medical treatment of idiopathic retroperitoneal fibrosis (RPF) increasingly is accepted. However, the optimum treatment strategy is still unclear. STUDY DESIGN Case series. SETTING & PARTICIPANTS Single tertiary care referral center. 24 patients with idiopathic RPF treated with prednisone for 1 year, if needed, with (urgent) renal(More)
BACKGROUND The estrogen receptor alpha (ESR1) is a mediator of estrogen response in the breast. The most studied variants in this gene are the PvuII and XbaI polymorphisms, which have been associated to lower sensitivity to estrogen. We evaluated whether these polymorphisms were associated with breast cancer risk by means of an association study in a(More)
PURPOSE Inhibition of COX-2 enzymes is a frequently suggested mechanism for the beneficial effects of NSAIDs on carcinogenesis. The aim of this study was to explore the role of cumulative NSAID use on four common non-skin related cancers and modification by COX-2 G(-765)C genotype. PATIENTS AND METHODS 7621 participants of The Rotterdam Study were(More)
While angiotensinogen (AGT) seems to have anti proliferative properties, angiotensin II (ATII) is a potent growth factor and it mediates its actions through the angiotensin type 1 receptor (AGTR1). In the AGT gene, the M235T polymorphism has been associated with the variation in angiotensinogen levels and in the AGTR1 gene; the C573T variant is associated(More)
BACKGROUND Recently, the number of performed CT-angiographies to diagnose pulmonary embolism (PE) rised markedly, while the incidence of PE hardly increased. This low yield of CT-angiography leads to more patients exposed to radiation and higher costs. AIM The diagnostic value of age, C-reactive protein (CRP) and D-dimer in PE was investigated.(More)
IGF-I is an important growth factor for the mammary gland. We evaluated the relationship of the IGF-I CA(n) polymorphism with breast cancer risk in Caucasian postmenopausal women and performed a meta-analysis of published data. The IGF-I CA(n) polymorphism was genotyped in 4091 from the Rotterdam Study. A disease-free survival analysis was performed along(More)
