The first part looks into methodology of observational studies. It shows that biases in observational studies may be an explanation why statins seem to have many unintended effects. The second part looks into bleeding complications and shows that patient with three concomitant anticoagulants experience high major bleeding rates. Also, a study was performed in which plasma and DNA of participants was collected, to identify risk factors for major bleeds in the future. The first results show that damage to vessel walls increases the risk of major bleeding. Interventions to reduce the number of bleeding events were to dose nadroparin od instead of bid. In addition, multi-dose drug dispensing may increase adherence of medication. Also, vitamin K1 tablets are easier to ingest and this thesis shows that the tablets are as effective in reducing the INR as the oral solution. Show less

It illustrates the prevalence of FNAIT among pregnant women and the risk of adverse outcome, outlines current management, evaluates risks of missing a diagnosis of FNAIT, studies the efficacy of a lower dose of immunoglobulins in preventing bleedingcomplications,shows the time of bleeding onset of fetal ICH during pregnancy and illustrates the longterm outcome of children with ICH.
