A randomized trial comparing conventional cytology to liquid-based cytology and computer assistance.
2012
Liquid-based cytology (LBC) has replaced conventional cytology (CC) for cervical cancer screening in some countries. However, it remains unclear whether LBC is superior to CC. A randomized controlled trial was conducted between August 2007 and March 2009 in Germany to compare LBC, alone and in combination with computer-assisted imaging technology (CAS), to CC in the detection of histologically confirmed cervical intraepithelial neoplasia (CIN). The main outcome measures were detection rates, relative sensitivities, positive predictive values (PPVs) and relative PPVs comparing LBC without and with CAS to CC. Primary histological outcome was CIN2 or higher. Included were 20,627 women particip…
Population attributable risk for ovarian cancer
2000
Parity, oral contraceptive (OC) use, age at menopause, a family history of the disease and selected aspects of diet have been related to the risk of ovarian cancer. The quantification of their impact on a population level may help focus and rank the importance of potential prevention strategies. Using data from a case-control study conducted in Italy between 1983 and 1991 on 971 ovarian cancer cases and 2758 control women we computed the multivariate relative risk estimates, and population attributable risks (PARs), i.e. the proportion of ovarian cancers that would have been avoided if a given exposure had not been present in the population. Overall, the PARs were 5% for nulliparity, 12% fo…
Epoetin alfa improves anemia and anemia-related, patient-reported outcomes in patients with breast cancer receiving myelotoxic chemotherapy: results …
2010
This study evaluated the effects of epoetin alfa on patient-reported outcomes in patients with breast cancer receiving myelotoxic chemotherapy. Early intervention with epoetin alfa was well tolerated and improved anemia-related patient-reported outcomes.
Lack of association of a functional catechol-O-methyltransferase gene polymorphism with risk of tobacco smoking: results from a multicenter case-cont…
2013
Background The catechol-O-methyltransferase (COMT) modulates dopaminergic neurotransmission in the prefrontal cortex as well as in the mesolimbic reward system. Since the reward system mediates addictive behavior, the COMT gene is a strong candidate gene regarding the pathophysiology of tobacco dependence and smoking behavior. Because of rather conflicting results in previous studies, the purpose of the present study was to test for association between a functional genetic variant in the COMT gene (single nucleotide polymorphism [SNP] rs4680) and tobacco smoking behavior. Methods In a population-based case-control multicenter study designed for tobacco addiction research, a total of 551 cur…
PAI-1 Levels are Related to Insulin Resistance and Carotid Atherosclerosis in Subjects with Familial Combined Hyperlipidemia
2017
Familial combined hyperlipidemia (FCH) is a primary atherogenic dyslipidemia with insulin resistance and increased cardiovascular risk. Plasminogen activator inhibitor type 1 (PAI-1) and myeloperoxidase (MPO) activity are associated with proinflammatory and atherothrombotic risk. Our aim was to study the role played by PAI-1 and MPO activity in the carotid atherosclerosis prevalence in FCH subjects. 36 FCH unrelated subjects (17 women) were matched by age and body weight with 36 healthy normolipidemic subjects (19 female). Blood lipids, glucose, insulin, insulin resistance (homeostasis model assessment (HOMA)), MPO, and PAI-1 were determined in both groups. Carotid intima media thickness (…
Is local stiffness, as measured by radio frequency, more sensitive than intima-media thickness?
2013
Aim: The aim of our study was to explore the changes in common carotid arterial intima-media thickness (CCA IMT) and local arterial stiffness to evaluate, non-invasively, early vascular disease in patients with cardiovascular (CV) risk factors and "normal" carotid IMT (6.05 m/s better identified, among patients with IMT <0.9mm, those with cardiovascular risk factors (sensitivity 82.0 % specificity 62.0 %; AUC 0.73). Conclusion. Increased stiffness is a result of change both in quantity and quality of the arterial wall. Arterial functional changes and distention alterations may herald the onset of vascular disease before manifestation of symptoms or detection of preclinical atherosclerotic l…
Possible misclassification of cardiovascular risk by SCORE in antisynthetase syndrome: results of the pilot multicenter study RI.CAR.D.A
2020
Abstract Objectives To test the ability of an established traditional cardiovascular (CV) risk prediction score [Systematic COronary Risk Evaluation (SCORE)] and its EULAR modified version (mSCORE) to identify antisynthetase syndrome (ASyS) patients at high CV risk and to examine for the first time associations of CV and cerebrovascular surrogate markers with clinical and immunological ASyS parameters. Methods SCORE/mSCORE and the gold standard marker of aortic stiffness [carotid-femoral pulse wave velocity (cfPWV)] were examined in ASyS patients and healthy controls. Moreover, sonography of the common- (CCA) and internal- (ICA) carotid arteries was performed in subsets of both groups, eval…
Relation between diagnosis of atheromatous plaque from orthopantomographs and cardiovascular risk factors. A study of cases and control subjects.
2014
Background In recent years the use of orthopantomography has been proposed as a low-cost, reliable and non-invasive diagnostic medium for detecting atheromatous plaque. The purpose of this study was to correlate the presence of carotid calcifications (atheroma) in orthopantomographs with specific risk factors for cerebrovascular accidents (previous cerebrovascular accidents, arterial hypertension, and diabetes). Material and Methods The methods used in this observational study of cases and control subjects followed STROBE (Strengthening the Reporting of Observational studies in Epidemiology) recommendations. The study analyzed a total of 1,602 panoramic radiographs taken for dental diagnost…
Facilitating cartilage volume measurement using MRI.
2010
To compare quantitative cartilage volume measurement (CVM) using different slice thicknesses.Ten knees were scanned with a 1.5T MRI (Sonata, Siemens, Erlangen, Germany) using a 3D gradient echo sequence (FLASH, fast low-angle shot). Cartilage volume of the medial and lateral tibial plateau was measured by two independent readers in 1.5mm, 3.0mm and 5.0mm slices using the Argus software application. Accuracy and time effectiveness served as control parameters.Determining cartilage volume, time for calculation diminished for the lateral tibial plateau from 384.6+/-127.7s and 379.1+/-117.6s to 214.9+/-109.9s and 213.9+/-102.2s to 122.1+/-60.1s and 126.8+/-56.2s and for the medial tibial platea…
