Slow behavioral reorganization following experimental manipulation of caste ratios
Background-Fetal tachycardia may cause hydrops fetalis and lead to fetal death. No unanimity of opinion exists regarding the optimum treatment. This study evaluates our experience with transplacental sotalol therapy to treat fetal tachycardias in terms of safety and efficacy. Methods and Results-The charts of 21 patients who were treated with sotalol for fetal tachycardia were reviewed. Ten fetuses had atrial flutter (AF), 10 had supraventricular tachycardia (SVT), and I had VT. Hydrops fetalis was present in 9 fetuses. Drug treatment was successful in establishing sinus rhythm in 8 of 10 fetuses with AF and in 6 of 10 fetuses with SVT. The mortality rate in this study was 19% (4 of 21 fetuses 3 had SVT and 1 had AF); 3 deaths occurred just days after the initiation of sotalol therapy, and 1 occurred after a dosage increase. At birth, tachycardia was present in 6 infants. Two patients who converted to sinus rhythm in utero suffered from neurologic pathology postnatally. Conclusions-Fetal tachycardia is a serious condition in which treatment should be initiated, especially in the presence of hydrops fetalis, The high success rate in fetuses with AF suggests that sotalol should be considered a drug of first choice to treat fetal AF, The low conversion rate and the fact that 3 of the 4 deaths in this study occurred in fetuses with SVT indicate that the risks of sotalol therapy outweigh the benefits in this group and that sotalol should, therefore, be limited in the treatment of fetal SV
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.

Early nasogastric tube feeding in optimising treatment for hyperemesis gravidarum: The MOTHER randomised controlled trial (Maternal and Offspring outcomes after Treatment of HyperEmesis by Refeeding)
Background: Hyperemesis gravidarum (HG), or intractable vomiting during pregnancy, is the single most frequent cause of hospital admission in early pregnancy. HG has a major impact on maternal quality of life and has repeatedly been associated with poor pregnancy outcome such as low birth weight. Currently, women with HG are admitted to hospital for intravenous fluid replacement, without receiving specific nutritional attention. Nasogastric tube feeding is sometimes used as last resort treatment. At present no randomised trials on dietary or rehydration interventions have been performed. Small observational studies indicate that enteral tube feeding may have the ability to effectively treat dehydration and malnutrition and alleviate nausea and vomiting symptoms. We aim to evaluate the effectiveness of early enteral tube feeding in addition to standard care on nausea and vomiting symptoms and pregnancy outcomes in HG patients. Methods/Design: The MOTHER trial is a multicentre open label randomised controlled trial ( www.studies-obsgyn.nl/mother ). Women ≥ 18 years hospitalised for HG between 5 + 0 and 19 + 6 weeks gestation are eligible for participation. After informed consent participants are randomly allocated to standard care with intravenous rehydration or early enteral tube feeding in addition to standard care. All women keep a weekly diary to record symptoms and dietary intake until 20 weeks gestation. The primary outcome will be neonatal birth weight. Secondary outcomes will be the 24-h Pregnancy Unique Quantification of Emesis and nausea score (PUQE-24), maternal weight gain, dietary intake, duration of hospital stay, number of readmissions, quality of life and side-effects. Also gestational age at birth, placental weight, umbilical cord plasma lipid concentration and neonatal morbidity will be evaluated. Analysis will be according to the intention to treat principle. Discussion: With this trial we aim to clarify whether early enteral tube feeding is more effective in treating HG than intravenous rehydration alone and improves pregnancy outcome.

Induction of labor with a Foley catheter and the risk of subsequent preterm birth: A follow-up study of two randomized controlled trials (PROBAAT-1 and -2)
OBJECTIVE:The objective of this study was to evaluate the preterm birth rate in a subsequent pregnancy in women who had undergone term induction with a Foley catheter in comparison to induction with prostaglandins. METHODS:This was a follow-up study of two large randomized controlled trials. In the original trials (PROBAAT-1 and PROBAAT-2), women with a term, singleton pregnancy in cephalic presentation with an indication for labor induction were randomized to either a 30cc Foley catheter or prostaglandins (i.e. vaginal prostaglandin E2 in PROBAAT 1 and oral misoprostol in PROBAAT 2). The main outcome measures were preterm birth <37 weeks gestation and preterm birth <34 weeks gestation. Data were collected from hospital charts on subsequent pregnancies from hospitals participating in this follow-up study. RESULTS:14 hospitals agreed to participate in this follow-up study. Of the 1142 eligible women, 162 women (14%) were lost to follow-up. Of the 572 women randomized to a Foley catheter, 251 women had a subsequent pregnancy beyond 16 weeks gestation, versus 258 women of the 570 women who received prostaglandins. There were no differences in baseline characteristics. The overall preterm birth rate was 9/251 (3.6%) in the Foley catheter group versus 10/258 (3.9%) in the prostaglandin group (RR 0.93; 95%CI 0.38-2.24), with spontaneous preterm birth rates of 5/251 (2.0%) versus 5/258 (1.9%) respectively (RR 1.03, 95%CI 0.30-3.51). CONCLUSIONS:In women with a singleton term pregnancy, induction of labor with a 30cc Foley catheter is not associated with an increased risk of preterm birth in a subsequent pregnancy as compared to induction of labor with prostaglandins.

Induction of labor with Foley catheter and risk of subsequent preterm birth: follow-up study of two randomized controlled trials (PROBAAT-1 and -2)
Objective: To evaluate the rate of preterm birth (PTB) in a subsequent pregnancy in women who had undergone term induction using a Foley catheter compared with prostaglandins. Methods: This was a follow-up study of two large randomized controlled trials (PROBAAT-1 and PROBAAT-2). In the original trials, women with a term singleton pregnancy with the fetus in cephalic presentation and with an indication for labor induction were randomized to receive either a 30-mL Foley catheter or prostaglandins (vaginal prostaglandin E2 in PROBAAT-1 and oral misoprostol in PROBAAT-2). Data on subsequent ongoing pregnancies > 16 weeks’ gestation were collected from hospital charts from clinics participating in this follow-up study. The main outcome measure was preterm birth 16 weeks' gestation in the Foley catheter and prostaglandin groups, respectively. There were no differences in baseline characteristics between the groups. The overall rate of PTB in a subsequent pregnancy was 9/251 (3.6%) in the Foley catheter group vs 10/258 (3.9%) in the prostaglandin group (relative risk (RR), 0.93; 95% CI, 0.38–2.24), and the rate of spontaneous PTB was 5/251 (2.0%) vs 5/258 (1.9%) (RR, 1.03; 95% CI, 0.30–3.51). Conclusion: In women with term singleton pregnancy, induction of labor using a 30-mL Foley catheter is not associated with an increased risk of PTB in a subsequent pregnancy, as compared to induction of labor using prostaglandins
Association of adverse perinatal outcomes of intrahepatic cholestasis of pregnancy with biochemical markers
__Background__ Intrahepatic cholestasis of pregnancy is associated with adverse perinatal outcomes, but the association
with the concentration of specific biochemical markers is unclear. We aimed to quantify the adverse perinatal effects
of intrahepatic cholestasis of pregnancy in women with increased serum bile acid concentrations and determine
whether elevated bile acid concentrations were associated with the risk of stillbirth and preterm birth.
__Methods__ We did a systematic review by searching PubMed, Web of Science, and Embase databases for studies
published from database inception to June 1, 2018, reporting perinatal outcomes for women with intrahepatic
cholestasis of pregnancy when serum bile acid concentrations were available. Inclusion criteria were studies defining
intrahepatic cholestasis of pregnancy based upon pruritus and elevated serum bile acid concentrations, with or
without raised liver aminotransferase concentrations. Eligible studies were case-control, cohort, and populationbased studies, and randomised controlled trials, with at least 30 participants, and that reported bile acid concentrations
and perinatal outcomes. Studies at potential higher risk of reporter bias were excluded, including case reports, studies
not comprising cohorts, or successive cases seen in a unit; we also excluded studies with high risk of bias from
groups selected (eg, a subgroup of babies with poor outcomes were explicitly excluded), conference abstracts, and
Letters to the Editor without clear peer review. We also included unpublished data from two UK hospitals. We did a
random effects meta-analysis to determine risk of adverse perinatal outcomes. Aggregate data for maternal and
perinatal outcomes were extracted from case-control studies, and individual patient data (IPD) were requested from
study authors for all types of study (as no control group was required for the IPD analysis) to assess associations
between biochemical markers and adverse outcomes using logistic and stepwise logistic regression. This study is
registered with PROSPERO, number CRD42017069134.
__Findings__ We assessed 109 full-text articles, of which 23 studies were eligible for the aggregate data meta-analysis
(5557 intrahepatic cholestasis of pregnancy cases and 165136 controls), and 27 provided IPD (5269 intrahepatic
cholestasis of pregnancy cases). Stillbirth occurred in 45 (0·91%) of 4936 intrahepatic cholestasis of pregnancy cases
and 519 (0·32%) of 163947 control pregnancies (odds ratio [OR] 1·46 [95% CI 0·73–2·89]
Clinical characteristics of women captured by extending the definition of severe postpartum haemorrhage with 'refractoriness to treatment': a cohort study
Background: The absence of a uniform and clinically relevant definition of severe postpartum haemorrhage
hampers comparative studies and optimization of clinical management. The concept of persistent postpartum
haemorrhage, based on refractoriness to initial first-line treatment, was proposed as an alternative to common
definitions that are either based on estimations of blood loss or transfused units of packed red blood cells
(RBC). We compared characteristics and outcomes of women with severe postpartum haemorrhage captured
by these three types of definitions.
Methods: In this large retrospective cohort study in 61 hospitals in the Netherlands we included 1391 consecutive
women with postpartum haemorrhage who received either ≥4 units of RBC or a multicomponent transfusion. Clinical
characteristics and outcomes of women with severe postpartum haemorrhage defined as persistent postpartum
haemorrhage were compared to definitions based on estimated blood loss or transfused units of RBC within 24 h
following birth. Adverse maternal outcome was a composite of maternal mortality, hysterectomy, arterial embolisation
and intensive care unit admission.
Results: One thousand two hundred sixty out of 1391 women (90.6%) with postpartum haemorrhage fulfilled the
definition of persistent postpartum haemorrhage. The majority, 820/1260 (65.1%), fulfilled this definition within 1 h
following birth, compared to 819/1391 (58.7%) applying the definition of ≥1 L blood loss and 37/845 (4.4%) applying
the definition of ≥4 units of RBC. The definition persistent postpartum haemorrhage captured 430/471 adverse maternal
outcomes (91.3%), compared to 471/471 (100%) for ≥1 L blood loss and 383/471 (81.3%) for ≥4 units of RBC. Persistent
postpartum haemorrhage did not capture all adverse outcomes because of missing data on timing of initial, first-line
treatment.
Conclusion: The definition persistent postpartum haemo
Ischaemic heart disease during pregnancy or post-partum: systematic review and case series
Contains fulltext :
152401.pdf (publisher's version ) (Open Access)The risk of manifestations of ischaemic heart disease (IHD) in fertile women is elevated during pregnancy and the post-partum period. With increasing maternal age and a higher prevalence of cardiac risk factors, the incidence of IHD during pregnancy is rising. However, information in the literature is scarce. We therefore performed a retrospective cohort study and systematically reviewed the overall (1975-2013) and contemporary (2005-2013) literature concerning IHD presenting during pregnancy or in the post-partum period. We report two cases of IHD with atypical presentation during pregnancy or post-partum. In our review, we describe 146 pregnancies, including 57 contemporary cases (2005-2013). Risk factors for IHD were present in 80 %. Of the cases of IHD, 71 % manifested in the third trimester or the post-partum period, and 95 % presented with chest pain. The main cause was coronary dissection (35 %), or thrombus/emboli (35 %) in the more contemporary group. Maternal mortality was 8 % (6 % in the contemporary group), and the main cardiac complication was ventricular tachycardia (n = 17). Premature delivery rate was 56 %, and caesarean section was performed in 57 %. Perinatal mortality was 4 %. In conclusion, IHD during pregnancy or in the post-partum period has high maternal mortality and morbidity rates. Also, premature delivery and perinatal mortality rates are high
