Low dose aspirin in the prevention of recurrent spontaneous preterm labour - the APRIL study: A multicenter randomized placebo controlled trial
Background: Preterm birth (birth before 37 weeks of gestation) is a major problem in obstetrics and affects an estimated 15 million pregnancies worldwide annually. A history of previous preterm birth is the strongest risk factor for preterm birth, and recurrent spontaneous preterm birth affects more than 2.5 million pregnancies each year. A recent meta-analysis showed possible benefits of the use of low dose aspirin in the prevention of recurrent spontaneous preterm birth. We will assess the (cost-)effectiveness of low dose aspirin in comparison with placebo in the prevention of recurrent spontaneous preterm birth in a randomized clinical trial. Methods/design: Women with a singleton pregnancy and a history of spontaneous preterm birth in a singleton pregnancy (22-37 weeks of gestation) will be asked to participate in a multicenter, randomized, double blinded, placebo controlled trial. Women will be randomized to low dose aspirin (80 mg once daily) or placebo, initiated from 8 to 16 weeks up to maximal 36 weeks of gestation. The primary outcome measure will be preterm birth, defined as birth at a gestational age (GA) < 37 weeks. Secondary outcomes will be a composite of adverse neonatal outcome and maternal outcomes, including subgroups of prematurity, as well as intrauterine growth restriction (IUGR) and costs from a healthcare perspective. Preterm birth will be analyzed as a group, as well as separately for spontaneous or indicated onset. Analysis will be performed by intention to treat. In total, 406 pregnant women have to be randomized to show a reduction of 35% in preterm birth from 36 to 23%. If aspirin is effective in preventing preterm birth, we expect that there will be cost savings, because of the low costs of aspirin. To evaluate this, a cost-effectiveness analysis will be performed comparing preventive treatment with aspirin with placebo. Discussion: This trial will provide evidence as to whether or not low dose aspirin is (cost-) effective in reducing recurrence of spontaneous preterm birth. Trial registration: Clinical trial registration number of the Dutch Trial Register: NTR 5675. EudraCT-registration number: 2015-003220-31

Analysis of Publication Interest on Preterm Birth Over Two Decades
INTRODUCTION: Preterm birth (PTB) is one of the greatest challenges in obstetric and children's healthcare. PTB remains the most important cause of perinatal morbidity and mortality worldwide. We studied the number of publications concerning PTB over the last two decades using advanced bibliometric visualization methodology. We put the number of publications in perspective of growing awareness of PTB as a major health problem. METHODS: We analyzed publications over time and performed bibliometric analysis of publications on PTB in the Web of Science from 1997 to 2016. The subjects of publications were visualized using a term map showing the relevant terms occurring in titles and abstracts. RESULTS: We identified 47,811 publications. The annual number of publications on PTB increased significantly by 443% in 2016 (n = 5027) compared to 1997 (n = 1135). Obstetrics & Gynecology is the leading research field (with 10.4% on the subject PTB in 2016) followed closely by Pediatrics (7.6% on the subject PTB in 2016), within the field Public, Environmental & Occupational Health minimal increase was observed (only 1% was published on the subject PTB in 2016). The publications on PTB have increased at higher rates than the overall increase of publications. In recent years we found more publications on PTB describing epidemiology and clinical characteristics/outcomes whereas in earlier years publications focused more on translational, basic research. CONCLUSION: A significant increase in research concerning PTB was observed over the last two decades. This increase of publications is in line with the growing global awareness of the need to reduce PTB by clinical research
Comment on “Maternal and perinatal outcomes in pregnancy-associated melanoma. Report of two cases and a systematic literature review”
Primary sclerosing cholangitis and pregnancy
Primary sclerosing cholangitis is a progressive disease, and coincidentally in pregnancy it is rare. It is characterized by progressive inflammation and destruction of bile ducts finally resulting in liver failure. A rare case of primary sclerosing cholangitis in pregnancy is presented. The course of the pregnancy was marked by threatened preterm delivery and exacerbation of cholestasis. She was successfully treated with ursodeoxycholic acid (UDCA). Although, primary sclerosing cholangitis has both maternal and fetal effects on pregnancy, the overall outcome is favorable. Only few cases have been reported using high dose ursodeoxycholic acid for primary sclerosing cholangitis in pregnancy, it often improves pruritus but has no protection against stillbirth. Data on the safety to the fetus or neonate and long-term outcome are scarce
Associations between Migraine and Adverse Pregnancy Outcomes: Systematic Review and Meta-analysis
Importance Migraine is a highly prevalent disorder associated with cardiovascular diseases. Cardiovascular diseases are also associated with preeclampsia (PE). The adverse pregnancy outcomes PE, preterm birth (PTB), low birth weight (LBW), small for gestational age (SGA) and placental abruption share aspects in their pathophysiology, which are also found in patients with migraine, such as inflammatory stress and hypercoagulability. Objective To determine the association of adverse pregnancy outcomes including PE, PTB, LBW, SGA, and placental abruption with a history of migraine through a systematic review and meta-analysis. Evidence Acquisition MEDLINE (PubMed), the Cochrane Library, and EMBASE, were searched from inception to November 11, 2018. Cohort studies and case-control studies evaluating migraine history and pregnancy complications were eligible. Results Of 1388 screened references, 14 studies were included in the systematic review. There were higher risks of PE (odds ratio [OR], 2.07; 95% confidence interval [CI], 1.51-2.85; I2 = 76%) and LBW (OR, 1.18; 95% CI, 1.03-1.34; I2 = 9%) in women with migraine compared with women without migraine. We observed no significant association between history of migraine and PTB (OR, 1.23; 95% CI, 0.97-1.55; I2 = 61%) or SGA (OR, 1.06; 95% CI, 0.98-1.15; I2 = 0%). Conclusions A history of migraine is significantly associated with an increased risk of adverse pregnancy outcomes including PE and LBW. We hypothesize that shared pathophysiology due to underlying preclinical cardiovascular risk in women with migraine might play a role during pregnancy. Relevance Pregnant women with a history of migraine should be considered at higher risk of adverse pregnancy outcomes and should be informed, monitored, and treated preventively accordingly. Target Audience Obstetricians and gynecologists, family physicians. Learning Objectives After completing this activity, the learner should be better able to: Describe the association between migraine and placenta-induced pregnancy complications; Explain the possibility of the developing preeclampsia in women with a history of migraine; and Assess the risk of preterm birth or a neonate with low birth weight or small for gestational age in women with migraine
