RESUMEN

OBJECTIVE: To determine the prevalence of depression, anxiety, and posttraumatic stress disorder (PTSD) years after hyperemesis gravidarum (HG) and its association with HG severity. MATERIAL AND METHODS: This prospective cohort study consisted of a follow-up of 215 women admitted for HG, who were eligible to participate in a randomized controlled trial and either declined or agreed to be randomized between 2013 and 2016 in 19 hospitals in the Netherlands. Participants completed the Hospital Anxiety and Depression Scale (HADS) six weeks postpartum and during follow-up and the PTSD checklist for DSM-5 (PCL-5) during follow-up. An anxiety or depression score ≥8 is indicative of an anxiety or depression disorder and a PCL-5 ≥ 31 indicative of PTSD. Measures of HG severity were symptom severity (PUQE-24: Pregnancy Unique Quantification of Emesis), weight change, duration of admissions, readmissions, and admissions after the first trimester. RESULTS: About 54/215 participants completed the HADS six weeks postpartum and 73/215 participants completed the follow-up questionnaire, on average 4.5 years later. Six weeks postpartum, 13 participants (24.1%) had an anxiety score ≥8 and 11 participants (20.4%) a depression score ≥8. During follow-up, 29 participants (39.7%) had an anxiety score ≥8, 20 participants (27.4%) a depression score ≥8, and 16 participants (21.9%) a PCL-5 ≥ 31.Multivariable logistic regression analysis showed that for every additional point of the mean PUQE-24 three weeks after inclusion, the likelihood of having an anxiety score ≥8 and PCL-5 ≥ 31 at follow-up increased with OR 1.41 (95% CI: 1.10;1.79) and OR 1.49 (95% CI: 1.06;2.10) respectively. CONCLUSION: Depression, anxiety, and PTSD symptoms are common years after HG occurred.

RESUMEN

This study aimed to investigate the association between hyperemesis gravidarum (HG) severity and early enteral tube feeding on cardiometabolic markers in offspring cord blood. We included women admitted for HG, who participated in the MOTHER randomised controlled trial (RCT) and observational cohort. The MOTHER RCT showed that early enteral tube feeding in addition to standard care did not affect symptoms/birth outcomes. Among RCT and cohort participants, we assessed how HG severity affected lipid, c-peptide, glucose and free thyroxine cord blood levels. HG severity measures were severity of vomiting at inclusion and 3 weeks after inclusion, pregnancy weight gain and 24-h energy intake at inclusion, readmissions and duration of hospital admissions. Cord blood measures were also compared between RCT participants allocated to enteral tube feeding and those receiving standard care. Between 2013-2016, 215 women were included: 115 RCT and 100 cohort participants. Eighty-one cord blood samples were available. Univariable not multivariable regression analysis showed that lower maternal weight gain was associated with higher cord blood glucose levels (ß: -0·08, 95% CI -0·16, -0·00). Lower maternal weight gain was associated with higher Apo-B cord blood levels in multivariable regression analysis (ß: -0·01, 95% CI -0·02, -0·01). No associations were found between other HG severity measures or allocation to enteral tube feeding and cord blood cardiometabolic markers. In conclusion, while lower maternal weight gain was associated with higher Apo-B cord blood levels, no other HG severity measures were linked with cord blood cardiometabolic markers, nor were these markers affected by enteral tube feeding.

RESUMEN

INTRODUCTION: Hyperemesis gravidarum (HG) complicates 1% of pregnancies and has a major impact on maternal quality of life and well-being. We know very little about HG's long-term impact after an affected pregnancy, including recurrence rates in future pregnancies, which is essential information for women considering subsequent pregnancies. In this study, we aimed to prospectively measure the recurrence rate of HG and the number of postponed and terminated subsequent pregnancies due to HG. We also aimed to evaluate if there were predictive factors that could identify women at increased risk for HG recurrence, and postponing and terminating subsequent pregnancies. MATERIAL AND METHODS: We conducted a prospective cohort study. A total of 215 women admitted for HG to public hospitals in the Netherlands were enrolled in the original MOTHER randomized controlled trial and associated observational cohort. Seventy-three women were included in this follow-up study. Data were collected through an online questionnaire. Recurrent HG was defined as vomiting symptoms accompanied by any of the following: multiple medication use, weight loss, admission, tube feeding or if nausea and vomiting symptoms were severe enough to affect life and/or work. Outcome measures were recurrence, postponing, and termination rates due to HG. Univariable logistic regression analysis was used to identify predictive factors associated with HG recurrence, and postponing and terminating subsequent pregnancies. RESULTS: Thirty-five women (48%) became pregnant again of whom 40% had postponed their pregnancy due to HG. HG recurred in 89% of pregnancies. One woman terminated and eight women (23%) considered terminating their pregnancy because of recurrent HG. Twenty-four out of 38 women did not get pregnant again because of HG in the past. Univariable logistic regression analysis identifying possible predictive factors found that having a western background was associated with having weight loss due to recurrent HG in subsequent pregnancies (odds ratio 12.9, 95% CI 1.3-130.5, p = 0.03). CONCLUSIONS: High rates of HG recurrence and a high number of postponed pregnancies due to HG were observed. Women can be informed of a high chance of recurrence to enable informed family planning.

RESUMEN

INTRODUCTION: Little is known about the pathophysiology of hyperemesis gravidarum (HG). Proposed underlying causes are multifactorial and thyroid function is hypothesized to be causally involved. In this study, we aimed to assess the utility of thyroid-stimulating hormone (TSH) and free thyroxine (FT4) as a marker and predictor for the severity and clinical course of HG. MATERIAL AND METHODS: We conducted a prospective cohort study including women admitted for HG between 5 and 20 weeks of gestation in 19 hospitals in the Netherlands. Women with a medical history of thyroid disease were excluded. TSH and FT4 were measured at study entry. To adjust for gestational age, we calculated TSH multiples of the median (MoM). We assessed HG severity at study entry as severity of nausea and vomiting (by the Pregnancy Unique Quantification of Emesis and nausea score), weight change compared with prepregnancy weight, and quality of life. We assessed the clinical course of HG as severity of nausea and vomiting and quality of life 1 week after inclusion, duration of hospital admissions, and readmissions. We performed multivariable regression analysis with absolute TSH, TSH MoMs, and FT4. RESULTS: Between 2013 and 2016, 215 women participated in the cohort. TSH, TSH MoM, and FT4 were available for, respectively, 150, 126, and 106 of these women. Multivariable linear regression analysis showed that lower TSH MoM was significantly associated with increased weight loss or lower weight gain at study entry (ΔKg; ß = 2.00, 95% CI 0.47-3.53), whereas absolute TSH and FT4 were not. Lower TSH, not lower TSH MoM or FT4, was significantly associated with lower nausea and vomiting scores 1 week after inclusion (ß = 1.74, 95% CI 0.36-3.11). TSH and FT4 showed no association with any of the other markers of the severity or clinical course of HG. Twenty-one out of 215 (9.8%) women had gestational transient thyrotoxicosis. Women with gestational transient thyrotoxicosis had a lower quality of life 1 week after inclusion than women with no gestational transient thyrotoxicosis (p = 0.03). CONCLUSIONS: Our findings show an inconsistent role for TSH, TSH MoM, or FT4 at time of admission and provide little guidance on the severity and clinical course of HG.

RESUMEN

OBJECTIVE: We aimed to identify determinants that predict hyperemesis gravidarum (HG) disease course and severity. STUDY DESIGN: For this study, we combined data of the Maternal and Offspring outcomes after Treatment of HyperEmesis by Refeeding (MOTHER) randomized controlled trial (RCT) and its associated observational cohort with non-randomised patients. Between October 2013 and March 2016, in 19 hospitals in the Netherlands, women hospitalised for HG were approached for study participation. In total, 215 pregnant women provided consent for participation. We excluded women enrolled during a readmission (n = 24). Determinants were defined as patient characteristics and clinical features, available to clinicians at first hospital admission. Patient characteristics included i.e. age, ethnicity, socio-economic status, history of mental health disease and HG and gravidity. Clinical features included weight loss compared to pre-pregnancy weight and symptom severity measured with Pregnancy Unique Quantification of Emesis (PUQE-24) questionnaire and the Nausea and Vomiting in Pregnancy specific Quality of Life questionnaire (NVPQoL). Outcome measures were measures of HG disease severity present at 1 week after hospital admission, including weight change, PUQE-24 and NVPQoL scores. Total days of admission hospital admission and readmission were also considered outcome measures. RESULTS: We found that high PUQE-24 and NVPQoL scores at hospital admission were associated with those 1 week after hospital admission (difference (ß) 0.36, 95 %CI 0.16 to 0.57 and 0.70,95 %CI 0.45-1.1). PUQE-24 and NVPQoL scores were not associated with other outcome measures. None of the patient characteristics were associated with any of the outcome measures. CONCLUSION: Our findings suggest that the PUQE-24 and NVPQoL questionnaires can identify women that maintain high symptom scores a week after admission, but that patient characteristics cannot be used as determinants of HG disease course and severity.

RESUMEN

OBJECTIVE:  To compare the effectiveness of the oxytocin receptor antagonist atosiban with the beta mimetic fenoterol as uterine relaxants in women undergoing external cephalic version (ECV) for breech presentation. DESIGN:  Multicentre, open label, randomised controlled trial. SETTING:  Eight hospitals in the Netherlands, August 2009 to May 2014. PARTICIPANTS:  830 women with a singleton fetus in breech presentation and a gestational age of more than 34 weeks were randomly allocated in a 1:1 ratio to either 6.75 mg atosiban (n=416) or 40 µg fenoterol (n=414) intravenously for uterine relaxation before ECV. MAIN OUTCOME MEASURES:  The primary outcome measures were a fetus in cephalic position 30 minutes after the procedure and cephalic presentation at delivery. Secondary outcome measures were mode of delivery, incidence of fetal and maternal complications, and drug related adverse events. All analyses were done on an intention-to-treat basis. RESULTS:  Cephalic position 30 minutes after ECV occurred significantly less in the atosiban group than in the fenoterol group (34% v 40%, relative risk 0.73, 95% confidence interval 0.55 to 0.93). Presentation at birth was cephalic in 35% (n=139) of the atosiban group and 40% (n=166) of the fenoterol group (0.86, 0.72 to 1.03), and caesarean delivery was performed in 60% (n=240) of women in the atosiban group and 55% (n=218) in the fenoterol group (1.09, 0.96 to 1.20). No significant differences were found in neonatal outcomes or drug related adverse events. CONCLUSIONS:  In women undergoing ECV for breech presentation, uterine relaxation with fenoterol increases the rate of cephalic presentation 30 minutes after the procedure. No statistically significant difference was found for cephalic presentation at delivery. TRIAL REGISTRATION:  Dutch Trial Register, NTR 1877.

RESUMEN

OBJECTIVE: To identify potential predictors for failed vacuum-assisted delivery. STUDY DESIGN: Retrospective case-control study conducted in two perinatal centers in the Netherlands. Cases were women who underwent a failed vacuum-assisted delivery between 1997 and 2011. A failed vacuum extraction was defined as a delivery that was started as vacuum extraction but was converted to a cesarean section because of failure to progress. As controls we studied two successful vacuum extractions that were performed before the failed one. We used multivariable logistic regression to assess the risk for failed vacuum extraction. RESULTS: Between 1997 and 2011, 6734 trials of vacuum extraction were performed of which 309 failed (4.6%). These 309 cases were compared to the data of 618 women who underwent a successful vacuum extraction. Predictors for failed vacuum-assisted vaginal delivery were increasing gestational age (OR 1.2 per week), maternal height (OR 0.97 per cm), previous vaginal birth as compared to nulliparae (OR 0.32), estimated fetal weight ≥3750g as compared to <3250g (OR 5.7), epidural analgesia (OR 3.0), augmentation (OR 1.4), failure to progress as indication for trial of vacuum delivery (OR 1.7), station of descent of the fetal head (OR 0.31 per station more descended), and occiput posterior position (OR 2.6). The area under the receiver-operating characteristic curve of a prediction model integrating these indicators was 0.83. CONCLUSION: Failed vacuum extraction can be predicted accurately using both ante- and intrapartum characteristics. There is a strong need for prospective studies on the subject.

RESUMEN

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. TRIAL REGISTRATION NUMBER: NTR4197 . Date of registration: October 2(nd) 2013.

RESUMEN

Aim of this article is to examine if we could identify factors that predict cesarean section and instrumental vaginal delivery in women who had a successful external cephalic version. We used data from a previous randomized trial among 25 hospitals and their referring midwife practices in the Netherlands. With the data of this trial, we performed a cohort study among women attempting vaginal delivery after successful ECV. We evaluated whether maternal age, gestational age, parity, time interval between ECV and delivery, birth weight, neonatal gender, and induction of labor were predictive for a vaginal delivery on one hand or a CS or instrumental vaginal delivery on the other hand. Unadjusted and adjusted odds ratios were calculated with univariate and multivariate logistic regression analysis. Among 301 women who attempted vaginal delivery after a successful external cephalic version attempt, the cesarean section rate was 13% and the instrumental vaginal delivery rate 6%, resulting in a combined instrumental delivery rate of 19%. Nulliparity increased the risk of cesarean section (OR 2.7 (95% CI 1.2-6.1)) and instrumental delivery (OR 4.2 (95% CI 2.1-8.6)). Maternal age, gestational age at delivery, time interval between external cephalic version and delivery, birth weight and neonatal gender did not contribute to the prediction of failed spontaneous vaginal delivery. In our cohort of 301 women with a successful external cephalic version, nulliparity was the only one of seven factors that predicted the risk for cesarean section and instrumental vaginal delivery.

RESUMEN

OBJECTIVE: Currently, there is no consensus on the definition of hyperemesis gravidarum (HG; protracted vomiting in pregnancy) and no single widely used set of diagnostic criteria for HG. The various definitions rely on symptoms, sometimes in combination with laboratory tests. Through a systematic review, we aimed to summarize available evidence on the diagnostic value of biomarkers for HG. This could assist diagnosis and may shed light on the, as yet, not understood cause of the disorder. STUDY DESIGN: We searched Medline and Embase for articles about diagnostic biomarkers for either the presence or severity of HG or nausea and vomiting of pregnancy. We defined HG as any combination of nausea, vomiting, dehydration, weight loss, or hospitalization for nausea and/or vomiting in pregnancy, in the absence of any other obvious cause for these complaints. RESULTS: We found 81 articles on 9 biomarkers. Although 65% of all studies included only HG cases with ketonuria, we did not find an association between ketonuria and presence or severity of HG in 5 studies reporting on this association. Metaanalysis, with the use of the hierarchical summary receiver operating characteristics model, yielded an odds ratio of 3.2 (95% confidence interval, 2.0-5.1) of Heliobacter pylori for HG, as compared with asymptomatic control subjects (sensitivity, 73%; specificity, 55%). Studies on human chorionic gonadotropin and thyroid hormones, leptin, estradiol, progesterone, and white blood count showed inconsistent associations with HG; lymphocytes tended to be higher in women with HG. CONCLUSION: We did not find support for the use of ketonuria in the diagnosis of HG. H pylori serology might be useful in specific patients.

RESUMEN

BACKGROUND: Breech presentation occurs in 3 to 4% of all term pregnancies. External cephalic version (ECV) is proven effective to prevent vaginal breech deliveries and therefore it is recommended by clinical guidelines of the Royal Dutch Organisation for Midwives (KNOV) and the Dutch Society for Obstetrics and Gynaecology (NVOG). Implementation of ECV does not exceed 50 to 60% and probably less.We aim to improve the implementation of ECV to decrease maternal and neonatal morbidity and mortality due to breech presentations. This will be done by defining barriers and facilitators of implementation of ECV in the Netherlands. An innovative implementation strategy will be developed based on improved patient counselling and thorough instructions of health care providers for counselling. METHOD/DESIGN: The ultimate purpose of this implementation study is to improve counselling of pregnant women and information of clinicians to realize a better implementation of ECV.The first phase of the project is to detect the barriers and facilitators of ECV. The next step is to develop an implementation strategy to inform and counsel pregnant women with a breech presentation, and to inform and educate care providers. In the third phase, the effectiveness of the developed implementation strategy will be evaluated in a randomised trial. The study population is a random selection of midwives and gynaecologists from 60 to 100 hospitals and practices. Primary endpoints are number of counselled women. Secondary endpoints are process indicators, the amount of fetes in cephalic presentation at birth, complications due to ECV, the number of caesarean sections and perinatal condition of mother and child. Cost effectiveness of the implementation strategy will be measured. DISCUSSION: This study will provide evidence for the cost effectiveness of a structural implementation of external cephalic versions to reduce the number of breech presentations at term. TRIAL REGISTRATION: Dutch Trial Register (NTR): 1878.

RESUMEN

OBJECTIVE: To evaluate the performance of abdominal palpation as a screening test for intrauterine growth retardation (IUGR) in a low risk population, under standard practice conditions. STUDY DESIGN: Population based observational study of 6318 consecutive low risk singleton pregnancies. The Dutch obstetric system distinguishes low from high risk pregnancies. In the low risk group abdominal palpation as a screening test is performed by midwives. If a complication, like IUGR, during prenatal care is assessed, the women is referred to a consulted obstetrician. Ultrasound is performed by the consulted obstetrician. In case of sustained suspicion the women is selected as high risk. OUTCOME PARAMETERS: severe small for gestational age (SGA) birthweight below 2.3rd centile, all SGA birthweight below 10th centile, operative delivery, neonatal morbidity and perinatal mortality. Screening value of abdominal palpation, abdominal palpation combined with ultrasound, and the performance of high risk selection was assessed by conventional performance measures. RESULTS: Abdominal palpation as a screening test for IUGR is of limited value: the observed sensitivities were 28% for severe SGA and 21% for SGA p < or = 10, respectively. After ultrasound in case of sustained suspicion, the sensitivity in detection of severe SGA was 25% and positive predictive value (PPV) 16%. In detection of SGA p < or = 10 sensitivity was 15% and PPV 55%, which means 45% were false positives. The sensitivity of the Dutch obstetric system in selection of high risk pregnancies in detection of severe SGA was 53%, in detection of SGA p < or = 10 was 37%. Perinatal mortality was 0.9% (57/6318) and 32% of these cases were SGA. Six cases of fetal death were unrecognised during prenatal care (0.09%) and seem preventable. The prevalence of a 5 min Apgar Score < or = 7 was significantly higher in the SGA infants if SGA was defined as p < or = 10. CONCLUSIONS: The diagnostic performance of abdominal palpation as a screening test for IUGR detection in a low risk population is disappointing. However, various stratagems such as routine ultrasound do not improve detection rate or perinatal morbidity and mortality.

RESUMEN

OBJECTIVE: To determine the incidence and risk factors for standard and severe postpartum haemorrhage (PPH) in vaginally delivering nulliparous women, before and after risk stratification. STUDY DESIGN: A population-based cohort study in an unselected cohort nulliparous women (N = 3464) in 'The Zaanstreek' district, The Netherlands. Risk stratification is part of routine care, where midwives cover all obstetrical care for women with low risk pregnancies. RESULTS: The incidence of standard PPH (> or = 500 ml) and severe PPH (> or = 1000 ml) were 19 and 4.2%, respectively. A retained placenta occurred in 1.8%. These data show consistently slightly higher values as compared to studies in literature. The most important risk factors for standard and severe PPH were related to an abnormal third stage of labour-third stage > or = 30 min and retained placenta (in severe PPH: odds ratio (OR) 14.1, 95% confidence interval (CI) 10.4-19.1). High birth weight and perineal damage were less important, but independent, significant risk factors. In the low risk group (N = 1416), incidence of severe PPH was 4.0%. Independent risk factors for severe PPH were third stage > or = 30 min (incidence 7.1%, OR 3.6) and retained placenta (incidence 1.2%, OR 21.6). In 25% of the women with a prolonged third stage (> or = 30 min), third stage was complicated due to retained placenta and/or severe PPH (1.8% of the low risk group). CONCLUSIONS: The incidence of PPH in nulliparous women in this cohort was on average higher than published data, while the most important risk factors for standard and severe PPH, even after risk stratification, were the same. A prolonged third stage of labour has to be considered as abnormal, requiring specific action.
