METHODS We used data of the European Organisation for Research and Treatment of Cancer (EORTC) 55971 trial in(More)
BACKGROUND Some recently emerged lipid-lowering therapies are currently restricted to patients with homozygous familial hypercholesterolemia (HoFH), and studies are underway to also assess these therapies in patients with 'severe heterozygous FH (HeFH)'. However, no uniform definition of 'severe HeFH' exists, although untreated low-density lipoprotein(More)

INTRODUCTION The development of overweight is often measured with the body mass index (BMI). During childhood the BMI curve has two characteristic points: the adiposity rebound at 6 years and the BMI peak at 9 months of age. In this study, the associations between the BMI peak and body composition measures and blood pressure at age 5-6 years were(More)
OBJECTIVE To determine the risk of preterm birth in a subsequent twin pregnancy after previous singleton preterm birth. DESIGN Cohort study. SETTING Nationwide study in the Netherlands. POPULATION In all, 4071 nulliparous women who had a singleton delivery followed by a subsequent twin delivery between the years 1999 and 2007 were studied. METHODS(More)

PATIENTS AND METHOD 180 departments of paediatrics, nuclear medicine and children's(More)
BACKGROUND In the Netherlands separate reference charts have been developed for native and immigrant groups to deal with differences in growth patterns in later childhood. The use of these charts, however, is complicated by methodological issues; they do not represent all large Dutch immigrant groups in separate charts despite the differences that have been(More)
OBJECTIVE To investigate whether vaginal Group B Streptococcus (GBS) colonisation or other baseline characteristics of women with preterm premature rupture of membranes (PPROM) can help in identifying subgroups of women who would benefit from immediate delivery.
