In a population-based study of 23,511 women 50-67 years of age at the time of first screening, a striking relationship was found between parity and age at first childbirth, on the one hand, and two radiologic aspects of breast parenchymal pattern (dysplasia and prominent duct pattern), on the other. These relationships appeared to be causal.
In several studies it has been shown that breast cancer screening by means of mammography reduces breast cancer mortality. To ensure that when organising a service screening programme the aim is reached, it is necessary to control and monitor the process. This is possible by several methods. In this study, disease-free intervals and survival rates were used(More)
In a cohort of 25,000 women aged 40-65 years at intake in a periodic screening programme for breast cancer the occurrence of endometrial cancer was studied during a follow-up period of up to 18 years. The authors examined whether they could confirm the existence of a number of relationships between this cancer and some reproductive and anthropometric(More)
Prospective data of cardiovascular mortality in relation to the systolic blood pressure of women are scarce, especially when combined with other risk factors. The association between systolic blood pressure and cardiovascular mortality was therefore studied in a 10-year follow-up of a population of 13,740 Dutch women, born between 1911 and 1925 who(More)
OBJECTIVE A multiplex extended-spectrum beta-lactamase-producing Enterobacteriaceae (ESBL-E) quantitative polymerase chain reaction (qPCR), performed directly on rectal swabs, was compared with a culture-based protocol to study the discrepancies between the two methods, and identify existing challenges to apply this assay in routine clinical practice. The(More)
Assessment of the accuracy of diagnostic procedures has been made independent of the diagnostic criteria used by means of Relative Operating Characteristics (ROC) analysis. A ROC curve describes the mutual relationship between the sensitivity and specificity of a diagnostic decision on the basis of various diagnostic criteria. The construction of such ROC(More)
Rapid identification of patients colonized with carbapenemase-producing Enterobacteriaceae (CPE) is essential to prevent introduction and the spread of CPE in the hospital. This article presents the results of a new screening method to detect patients colonized with CPE within 24h after hospital admission. From high-risk patients rectal and throat swabs(More)
Sir, Mycoplasma genitalium causes sexually transmissible disease (STD). Approximately 4.5% of Dutch patients undergoing STD screening are infected with the bacterium. Although urogenital infections with M. genitalium are often treated with a single dose of 1 g azithromycin, the efficacy of this regimen has decreased worldwide from 85% to 60% over the past 7(More)
In medical usage, relative operating characteristics (ROC) refer to the symptoms, signs, and laboratory values used for making a diagnosis. Diagnosis analysis by ROC measures diagnosis performance independently of the diagnostic criteria used, thus revealing the arbitrary character of diagnosis. In order to carry out ROC analysis, the diagnosis has to be(More)
