The temporal order of fluctuations in atopic disease symptoms and attention-deficit/hyperactivity disorder symptoms: a time-series study in ADHD patients.

In a recent meta-analysis, we found that atopic diseases, like asthma and allergic rhinitis, occur more frequently prior to the onset of attention-deficit/hyperactivity disorder (ADHD). Our aim was to determine the temporal order of the association between daily fluctuations in atopic disease symptoms and in ADHD symptoms in individual participants. In this observational study among 21 participants, age 7-16 years, we performed a replicated time-series analysis of symptom fluctuations in asthma and/or allergic rhinitis and ADHD.

Cost-effectiveness analysis of Chlamydia trachomatis screening in Dutch pregnant women.

Chlamydia trachomatis infections during pregnancy may have serious consequences for women and their offspring. Chlamydial infections are largely asymptomatic. Hence, prevention is based on screening.

Knowledge and acceptability of Chlamydia trachomatis screening among pregnant women and their partners; a cross-sectional study.

Background: Chlamydia trachomatis infections in pregnancy can cause maternal disease, adverse pregnancy outcomes and neonatal disease, which is why chlamydia screening during pregnancy has been advocated. The effectiveness of a screening program depends on the knowledge of health care professionals, women and partners and the acceptability for screening of the target population. We assessed the knowledge of chlamydia infection among pregnant women and their partners in the Netherlands, their attitudes towards testing, and their experiences of being offered a chlamydia test.

Chlamydia trachomatis infection during pregnancy: knowledge, test practices, and attitudes of Dutch midwives.

Background: Chlamydia trachomatis infection in pregnancy may lead to adverse pregnancy outcomes. In the Netherlands, testing for C. trachomatis is based on risk assessment.

A clinical prediction rule for histological chorioamnionitis in preterm newborns.

Background: Histological chorioamnionitis (HC) is an intrauterine inflammatory process highly associated with preterm birth and adverse neonatal outcome. HC is often clinically silent and diagnosed postnatally by placental histology. Earlier identification could facilitate treatment individualisation to improve outcome in preterm newborns.
