RESUMEN

OBJECTIVES: To explore the impact of anti-hypertensive treatment of pregnancy-induced hypertension on foetal growth and hemodynamics in women with pre-existing diabetes. METHODS: A prospective cohort study of 247 consecutive pregnant women with pre-existing diabetes (152 type 1 diabetes; 95 type 2 diabetes), where tight anti-hypertensive treatment was initiated and intensified (mainly with methyldopa) when office blood pressure (BP) ≥135/85 mmHg and home BP ≥130/80 mmHg. Foetal growth was assessed by ultrasound at 27, 33 and 36 weeks and foetal hemodynamics were assessed by ultrasound Doppler before and 1-2 weeks after initiation of anti-hypertensive treatment. RESULTS: In 215 initially normotensive women, anti-hypertensive treatment for pregnancy-induced hypertensive disorders was initiated in 42 (20%), whilst 173 were left untreated. Chronic hypertension was present in 32 (13%). Anti-hypertensive treatment for pregnancy-induced hypertensive disorders was not associated with foetal growth deviation (linear mixed model, p = 0.681). At 27 weeks, mainly before initiation of anti-hypertensive treatment, the prevalence of small foetuses with an estimated foetal weight <10th percentile was 12% in women initiating anti-hypertensive treatment compared with 4% in untreated women (p = 0.054). These numbers were close to the prevalence of birth weight ≤10th percentile (small for gestational age (SGA)) (17% vs. 4%, p = 0.003). Pulsatility index in the umbilical and middle cerebral artery remained stable after the onset of anti-hypertensive treatment in a representative subgroup (n = 12, p = 0.941 and p = 0.799, respectively). CONCLUSION: There is no clear indication that antihypertensive treatment causes harm in this particular at-high-risk group of pregnant women with diabetes, such that a larger well-designed study to determine the value of tight antihypertensive control would be worthwhile.

RESUMEN

BACKGROUND: Collaborative skills learning in the form of dyad learning compared with individual learning has been shown to lead to non-inferior skills retention and transfer. However, we have limited knowledge on which learning activities improve collaborative skills training and how the number of collaborators may impact skills transfer. We explored the effects of skills training individually, in dyads, triads or tetrads on learning activities during training and on subsequent skills transfer. METHODS: In a randomised, controlled study, participants completed a pre-post-transfer-test set-up in groups of one to four. Participants completed 2 hours of obstetric ultrasound training. In the dyad, triad and tetrad group participants took turns actively handling the ultrasound probe. All performances were rated by two blinded experts using the Objective Structured Assessment of Ultrasound Skills (OSAUS) scale and a Global Rating Scale (GRS). All training was video recorded, and learning activities were analysed using the Interactive-Constructive-Active-Passive (ICAP) framework. RESULTS: One hundred one participants completed the simulation-based training, and ninety-seven completed the transfer test. Performance scores improved significantly from pre- to post-test for all groups (p < 0.001, ηp2 = 0.55). However, group size did not affect transfer test performance on OSAUS scores (p = 0.13, ηp2 = 0.06) or GRS scores (p = 0.23, ηp2 = 0.05). ICAP analyses of training activities showed that time spent on non-learning and passive learning activities increased with group size (p < 0.001, ηp2 = 0.31), whereas time spent on constructive and interactive learning activities was constant between groups compared with singles (p < 0.001, ηp2 = 0.72). CONCLUSION: Collaborative skills learning in groups of up to four did not impair skills transfer despite less hands-on time. This may be explained by a compensatory shift towards constructive and interactive learning activities that outweigh the effect of shorter hands-on time.

RESUMEN

INTRODUCTION: This report presents a rare case of spontaneous twin anemia-polycythemia sequence (TAPS) between two dichorionic fetuses in a spontaneous, homozygotic, dichorionic, triamniotic, triplet pregnancy treated with multiple intrauterine blood transfusions (IUTs) and partial exchange transfusions (PETs). CASE PRESENTATION: The pregnancy was diagnosed with stage IV TAPS at gestational week 25+1. The patient was treated with laser surgery combined with multiple IUTs and PETs. The triplets were delivered at a planned caesarean section at gestational week 28+1 with postnatal hemoglobin values of 18.21, 26.43, and 11.92 g/dL in triplet 1, 2, and 3, respectively. At 4 years of age, triplet 1 is considered healthy, triplet 2 is diagnosed with mild mental retardation, and triplet 3 with profound mental retardation and dystonic cerebral palsy. DISCUSSION: This is an extremely rare case of TAPS between dichorionic fetuses in a triplet pregnancy, and routine surveillance with measurement of middle cerebral artery peak systolic velocity in dichorionic pregnancies may contribute to the detection of similar cases in the future. Furthermore, this case contributes with rare long-term follow-up data of children treated for high-stage TAPS with multiple IUTs and PETs.

RESUMEN

Introduction: In the Kell blood group system, the K and k antigens are the clinically most important ones. Maternal anti-K IgG antibodies can lead to the demise of a K-positive fetus in early pregnancy. Intervention can save the fetus. Prenatal K status prediction of the fetus in early pregnancy is desirable and gives a good basis for pregnancy risk management. We present the results from 7 years of clinical experience in predicting fetal K status as well as some theoretical considerations relevant for design of the assay and evaluation of results. Methods: Blood was collected from 43 women, all immunized against K, at a mean gestational age of 18 weeks (range 10-38). A total of 56 consecutive samples were tested. The KEL *01.01 /KEL *02 single nucleotide variant that determines K status was amplified from maternal plasma DNA by PCR without allele specificity. The PCR product was sequenced by NGS technology, and the number of sequenced KEL *01.01 and KEL *02 reads were counted. Prediction of the fetal K status was based on this count and was compared with the serologically determined K status of the newborns. Results: All fetal K predictions were in accordance with postnatal serology where available (n = 34), using our current data analysis. Conclusion: We have developed an NGS-based method for the non-invasive prediction of fetal K status. This approach requires special considerations in terms of primer design, stringent preanalytical sample handling, and careful analytical procedures. We analyzed samples starting at GA 10 weeks and demonstrated the correct prediction of fetal K status. This assay enables timely clinical intervention in pregnancies at risk of hemolytic disease of the fetus and newborn caused by maternal anti-K IgG antibodies.

RESUMEN

BACKGROUND: The Rh blood group system has considerable clinical importance. The C, c, and E antigens are targets of alloantibodies. Anti-C, anti-c or anti-E alloreactive antibodies produced in pregnant women can cause anemia of a fetus carrying the corresponding antigens. AIMS: Based on NGS technology, we have developed a noninvasive diagnostic assay to predict the fetal blood group of C, c or E antigens by sequencing cell-free DNA (cfDNA) during pregnancy. MATERIALS AND METHODS: The SNVs underlying either the C, c or E antigens were PCR amplified and sequenced using NGS on a MiSeq instrument. The DNA sequences encoding the C, c or E antigen were counted, as were the number of total sequences. Based on the percentage of fetally derived target SNVs inherited from the father, the fetal blood group could be predicted. RESULTS: The results of 55 consecutive RHCE prenatal analyses with postnatal serological blood group determination of 30 newborns showed no discordant results. A threshold discerning positive from negative samples was set at 0.05% specific reads. DISCUSSION: Noninvasive, prenatal prediction of fetal blood groups by sequencing cfDNA for the detection of low-level RHCE*C, RHCE*c and RHCE*E sequences was established as an accurate and robust assay applicable for use in clinical settings.

RESUMEN

INTRODUCTION: The objective of this study was to explore the association between detection of fetal growth restriction and maternal-, healthcare provider- and organizational factors. MATERIAL AND METHODS: A historical, observational, multicentre study. All women who gave birth to a child with a birthweight <2.3rd centile from 1 September 2012 to 31 August 2015 in Zealand, Denmark, were included. The population was identified through the Danish Fetal Medicine Database. Medical charts were reviewed to obtain data regarding maternal characteristics and information on the healthcare professionals. Date of authorization for the midwives and obstetricians involved was extracted from the Danish Health Authorization Registry. Multivariable Cox regression models were used to identify predictors of antenatal detection of fetal growth restriction, and analyses were adjusted for hospital, body mass index, parity, the presence of at least one risk factor and experience of the first midwife, number of midwife visits, number of visits to a doctor, the experience of the consultant midwife or the educational level of the doctor, the number of scans and gaps in continuity of midwife-care. Antenatal detection was defined as an ultrasound estimated fetal weight <2.3rd centile (corresponding to -2 standard deviations) prior to delivery. RESULTS: Among 78 544 pregnancies, 3069 (3.9%) had a fetal growth restriction. Detection occurred in 31% of fetal growth-restricted pregnancies. Clinical experience (defined as years since graduation) of the first consultation midwife was positively associated with detection, with a hazard ratio [HR] of 1.15, 95% confidence interval [CI] 1.03-1.28), for every 10 years of additional experience. The hazard of detection increased with the number of midwife consultations (HR 1.15, 95% CI 1.05-1.26) and with multiparity (HR 1.28, 95% CI 1.03-1.58). After adjusting for all covariates, an unexplained difference between hospitals (P = .01) remained. CONCLUSIONS: The low-risk nullipara may constitute an overlooked group of women at increased risk of antenatal non-detection of fetal growth restriction. Being screened by experienced midwives during early pregnancy and having access to multiple midwife consultations may improve future diagnosis.

RESUMEN

INTRODUCTION: The aim of this study was to obtain expert consensus on the content of a curriculum for learning chorionic villus sampling (CVS) and amniocentesis (AC) and the items of an assessment tool to evaluate CVS and AC competence. METHODS: We used a 3-round iterative Delphi process. A steering committee supervised all processes. Seven international collaborators were identified to expand the breadth of the study internationally. The collaborators invited fetal medicine experts to participate as panelists. In the first round, the panelists suggested content for a CVS/AC curriculum and an assessment tool. The steering committee organized and condensed the suggested items and presented them to the panelists in round 2. In the second round, the panelists rated and commented on the suggested items. The results were processed by the steering committee and presented to the panelists in the third round, where final consensus was obtained. Consensus was defined as support by more than 80% of the panelists for an item. RESULTS: Eighty-six experts agreed to participate in the study. The panelists represented 16 countries across 4 continents. The final list of curricular content included 12 theoretical and practical items. The final assessment tool included 11 items, systematically divided into 5 categories: pre-procedure, procedure, post-procedure, nontechnical skills, and overall performance. These items were provided with behavioral scale anchors to rate performance, and an entrustment scale was used for the final overall assessment. CONCLUSION: We established consensus among international fetal medicine experts on content to be included in a CVS/AC curriculum and on an assessment tool to evaluate CVS/AC skills. These results are important to help transition current training and assessment methods from a time- and volume-based approach to a competency-based approach which is a key step in improving patient safety and outcomes for the 2 most common invasive procedures in fetal medicine.

RESUMEN

BACKGROUND: Laboratory monitoring of mother, fetus, and newborn in hemolytic disease of fetus and newborn (HDFN) aims to guide clinicians and the immunized women to focus on the most serious problems of alloimmunization and thus minimize the consequences of HDFN in general and of anti-D in particular. Here, we present the current approach of laboratory screening and testing for prevention and monitoring of HDFN at the Copenhagen University Hospital in Denmark. SUMMARY: All pregnant women are typed and screened in the 1st trimester. This serves to identify the RhD-negative pregnant women who at gestational age (GA) of 25 weeks are offered a second screen test and a non-invasive fetal RhD prediction. At GA 29 weeks, and again after delivery, non-immunized RhD-negative women carrying an RhD-positive fetus are offered Rh immunoglobulin. If the 1st trimester screen reveals an alloantibody, antenatal investigation is initiated. This also includes RhD-positive women with alloantibodies. Specificity and titer are determined, the fetal phenotype is predicted by non-invasive genotyping based on cell-free DNA (RhD, K, Rhc, RhC, RhE, ABO), and serial monitoring of titer commences. Based on titers and specificity, monitoring with serial peak systolic velocity measurements in the fetal middle cerebral artery to detect anemia will take place. Intrauterine transfusion is given when fetal anemia is suspected. Monitoring of the newborn by titer and survival of fetal red blood cells by flow cytometry will help predict the length of the recovery of the newborn.

RESUMEN

OBJECTIVE: To determine hemodynamic changes by Doppler ultrasound of the living fetus during 24 h after umbilical cord occlusion (UCO) in monochorionic diamniotic (MCDA) twin pregnancies. METHOD: We conducted a prospective observational study on fetuses undergoing UCO from 2015 to 2017. Doppler parameters peak systolic velocity (PSV) and umbilical pulsatility index (PI) were obtained in the middle cerebral artery (MCA), umbilical artery (UA) and ductus venosus (DV) before and right after UCO, and at 1, 3, 6, 12, and 24 h after. We used multiple of the median (MoM) to adjust for gestational age. Spaghetti plots visualized flow changes over time. Mixed model adjusting for paired longitudinal data compared the values at different time points. RESULTS: A total of 16 women were included. MCA-PSV dropped within the first hour after surgery from 0.91 to 0.82 MoM (p = 0.08). MCA-PI and UA-PI increased in the first hour from 0.75 to 0.91 MoM (p = 0.02) and 0.94 to 0.98 MoM (p = 0.22), respectively. The DV-PIV increased to 1.14 MoM 3 h after surgery (p = 0.07). The spaghetti plots illustrated the small changes within the first hours and showed a stabilization of flow measurements near initial values 24 h after UCO. CONCLUSION: Within the first hours after UCO the circulation of the survivor twin undergoes small hemodynamic changes.

RESUMEN

BACKGROUND: The treatment options for fetal chylothorax include thoracocentesis, thoracoamniotic shunting, and pleurodesis using OK-432. Knowledge on the long-term outcomes after treatment with OK-432 is limited. OBJECTIVE: The aim of this study was to assess the long-term outcomes of children treated in utero with OK-432. METHODS: We performed follow-up on pregnancies and children treated in utero with OK-432 between 2003 and 2009 at Copenhagen University Hospital Rigshospitalet for pleural effusions at gestational age (GA) 16+0-21+6 weeks. Anamnestic information, physical examination, pulmonary function test, neuropediatric examination, and intelligence testing using the Wechsler Intelligence Scale were used for evaluation. RESULTS: Fourteen cases, all chylothorax, were treated with OK-432. None had preterm premature rupture of membranes (PPROM), and the median GA at delivery was 38+5 (24+4-41+5) weeks. Twelve children were eligible for follow-up. The median age at follow-up was 11.4 (7.8-13.8) years. Pulmonary function was normal in all children and the mean full-scale IQ did not differ from that of normal children. Four children had a diagnosed medical condition, attention deficit disorder, or genetic syndrome. The remaining children had normal follow-up. CONCLUSION: Children treated with OK-432 have comparable survival rates and long-term neurodevelopmental outcomes to those treated with thoracoamniotic shunts. There seems to be a lower risk of procedure-related PPROM.

RESUMEN

INTRODUCTION: We sought to assess the incidence of severe neurodevelopmental impairment (NDI) in monochorionic twins treated for twin-twin transfusion syndrome (TTTS) and compare it to the incidence in uncomplicated monochorionic twins. MATERIAL AND METHODS: We included TTTS pregnancies treated by fetoscopic selective laser coagulation (FSLC) or umbilical cord occlusion (UCO) in 2004-2015. Primary outcome was severe NDI defined as cerebral palsy, bilateral blindness or bilateral deafness (ICD-10 diagnoses), and severe cognitive and/or motor delay (assessed by the Ages and Stages Questionnaires [ASQ]). RESULTS: A total of 124 children after TTTS and 98 controls were followed up at 25 months of age (SD 11.4). Severe NDI was found in 8.9% of the TTTS children (10.5% [9/86] after FSLC; 5.3% [2/38] after UCO) compared to 3.1% in the control group (p = 0.10). The odds ratio for severe NDI was 1.8 in cases versus controls (p = 0.37). The total ASQ score was significantly lower in the TTTS group than in controls (p = 0.03) after FSLC (p = 0.03) and after UCO (p = 0.14). DISCUSSION: Children after TTTS appear to have a higher risk of severe NDI and score significantly lower on the ASQ compared to monochorionic twins from uncomplicated pregnancies.

RESUMEN

INTRODUCTION: The false-positive rate in the prediction of fetal anemia is 10-15%. We investigated if a new, noninvasive MRI method used as a supplement to ultrasound could improve the prediction. METHODS: Fetuses suspected of anemia and controls were scanned in a 1.5-tesla MRI scanner 1-4 times during pregnancy. Cases were scanned before and after intrauterine blood transfusion with a T1-mapping MRI sequence in a cross-section of the umbilical vein. RESULTS: Inclusion of 8 cases and 11 controls resulted in 10 case scans (2 cases were included twice) and 33 control scans. In controls, the T1 relaxation time was 1,005-1,391 ms; in cases with severe anemia, 1,505-1,595 ms, moderate anemia 1,503-1,525 ms, and no/mild anemia 1,245-1,410 ms. After blood transfusions, values dropped to 1,123-1,288 ms. The mean value in moderate and severe anemic cases was 275 ms higher than in controls (95% CI 210-341 ms, p < 0.0001), and after blood transfusion it was comparable to controls (3 ms, 95% CI -62 to 68 ms, p = 0.934). A 1,450-ms cut-off would have identified all cases in need of blood transfusion with no false-positive cases. CONCLUSIONS: Our findings indicate a potential for this new MRI method to improve the prediction of fetal anemia as a supplement to ultrasound.

RESUMEN

OBJECTIVE: To explore the effect of adding simulation-based transvaginal ultrasound training to trainees' clinical training compared with only clinical training on quality of and efficiency of care. BACKGROUND: Simulation-based ultrasound training may be an effective adjunct to clinical training, but no studies have examined its effects on quality and efficiency of care. METHODS: Trainees from 4 University Hospitals in East Denmark were included (N = 54). Participants were randomized to either simulation-based ultrasound training and clinical training (intervention group, n = 28), or to clinical training only (control group, n = 26).The primary outcome was patient-reported discomfort during transvaginal ultrasound examinations performed by study participants. Secondary outcomes included patient-reported perceived safety and confidence in ultrasound provider. Finally, the need for trainee supervision or repeated patient examinations was recorded. RESULTS: In total, 1150 patient ratings were collected. The intervention was associated with a reduction of patient discomfort by 18.5% [95% confidence interval (CI), 10.7-25.5; P < 0.001), and with a 7.9% (95% CI, 0.5-14.7; P = 0.04) increase in perceived safety. The intervention group participants received 11.1% (95% CI, 2.5-18.9) higher scores on patients' confidence compared with control group participants (P = 0.01). When the number of days of clinical training was doubled, the odds for trainee supervision or repeated patient examination was reduced by 45.3% (95% CI, 33.5-55.1) and 19.8% (95% CI, 4.1-32.9) in the intervention and control group, respectively (P = 0.005). CONCLUSIONS: Simulation-based ultrasound training improved quality of care and reduced the need for repeated patient examination and trainee supervision.

RESUMEN

OBJECTIVES: The aim of the study was to explore whether learning curves on a virtual-reality (VR) sonographic simulator can be used to predict subsequent learning curves on a physical mannequin and learning curves during clinical training. METHODS: Twenty midwives completed a simulation-based training program in transvaginal sonography. The training was conducted on a VR simulator as well as on a physical mannequin. A subgroup of 6 participants underwent subsequent clinical training. During each of the 3 steps, the participants' performance was assessed using instruments with established validity evidence, and they advanced to the next level only after attaining predefined levels of performance. The number of repetitions and time needed to achieve predefined performance levels were recorded along with the performance scores in each setting. Finally, the outcomes were correlated across settings. RESULTS: A good correlation was found between time needed to achieve predefined performance levels on the VR simulator and the physical mannequin (Pearson correlation coefficient .78; P < .001). Performance scores on the VR simulator correlated well to the clinical performance scores (Pearson correlation coefficient .81; P = .049). No significant correlations were found between numbers of attempts needed to reach proficiency across the 3 different settings. A post hoc analysis found that the 50% fastest trainees at reaching proficiency during simulation-based training received higher clinical performance scores compared to trainees with scores placing them among the 50% slowest (P = .025). CONCLUSIONS: Performances during simulation-based sonography training may predict performance in related tasks and subsequent clinical learning curves.

RESUMEN

OBJECTIVE: To provide a model for conducting cost-effectiveness analyses in medical education. The model was based on a randomised trial examining the effects of training midwives to perform cervical length measurement (CLM) as compared with obstetricians on patients' waiting times. (CLM), as compared with obstetricians. METHODS: The model included four steps: (i) gathering data on training outcomes, (ii) assessing total costs and effects, (iii) calculating the incremental cost-effectiveness ratio (ICER) and (iv) estimating cost-effectiveness probability for different willingness to pay (WTP) values. To provide a model example, we conducted a randomised cost-effectiveness trial. Midwives were randomised to CLM training (midwife-performed CLMs) or no training (initial management by midwife, and CLM performed by obstetrician). Intervention-group participants underwent simulation-based and clinical training until they were proficient. During the following 6 months, waiting times from arrival to admission or discharge were recorded for women who presented with symptoms of pre-term labour. Outcomes for women managed by intervention and control-group participants were compared. These data were then used for the remaining steps of the cost-effectiveness model. RESULTS: Intervention-group participants needed a mean 268.2 (95% confidence interval [CI], 140.2-392.2) minutes of simulator training and a mean 7.3 (95% CI, 4.4-10.3) supervised scans to attain proficiency. Women who were scanned by intervention-group participants had significantly reduced waiting time compared with those managed by the control group (n = 65; mean difference, 36.6 [95% CI 7.3-65.8] minutes; p = 0.008), which corresponded to an ICER of 0.45 EUR minute(-1) . For WTP values less than EUR 0.26 minute(-1) , obstetrician-performed CLM was the most cost-effective strategy, whereas midwife-performed CLM was cost-effective for WTP values above EUR 0.73 minute(-1) . CONCLUSION: Cost-effectiveness models can be used to link quality of care to training costs. The example used in the present study demonstrated that different training strategies could be recommended as the most cost-effective depending on administrators' willingness to pay per unit of the outcome variable.

RESUMEN

OBJECTIVE: To describe the incidence of placenta previa and to assess neonatal morbidity and mortality in pregnancies with placenta previa after adjustment for previous cesarean section, smoking, multiparity, maternal age and in vitro fertilization. DESIGN: National cohort study. SETTING: Danish national IVF-, birth- and patient registers. POPULATION: All pregnancies in Denmark from 1978-2006 and a subpopulation of all singleton pregnancies during the years 2001-2006 with placenta previa (n=1721) compared to pregnancies without this diagnosis. METHODS: Incidence rates and multivariate analysis. MAIN OUTCOME MEASURES: Gestational age, birthweight, Apgar score after five minutes, stillbirth, neonatal mortality and admittance to neonatal intensive care unit. RESULTS: The incidence of placenta previa in Denmark was 0.54% in 2006. Neonates born after pregnancies with placenta previa had a higher risk of being born at a gestational age below 37 weeks (OR 8.6; 95%CI 7.5-9.9), having an Apgar score of ≤7 at five minutes (OR 2.7; 95%CI 2.0-3.7), being transferred to a neonatal intensive care unit (OR 4.3; 95%CI 3.8-4.9) and for stillbirth and neonatal mortality combined (OR 1.8; 95%CI 1.1-3.0), compared with neonates born in pregnancies without placenta previa. No increased risk of being small-for-gestational age was found (OR 1.0; 95%CI 1.0-1.2). CONCLUSION: When adjusting for confounders, neonates born after pregnancies with placenta previa had a significantly higher risk of being born preterm, having a low Apgar score, being transferred to neonatal intensive care, and death.

RESUMEN

The incidence of haemolytic disease of the foetus or newborn (HDFN) has decreased considerably in Denmark since the introduction of routine administration of prophylactic anti-D immunoglobulin to RhD-negative pregnant women carrying a RhD-positive foetus. RhD-positive pregnant women are screened for irregular antibodies only in the first trimester of their pregnancy, as their risk of clinically relevant immunisation during pregnancy has been considered very low. This is a case report of severe undetected alloimmunisation causing fatal HDFN after the first trimester in a RhD-positive woman.

RESUMEN

We describe a case of mirror syndrome. A 41-year-old woman, para 4, was referred to hospital at 32 weeks of gestational age with excessive oedema. She developed oliguria, mild hypertension and proteinuria. Fetal ultrasound confirmed severe hydrops fetalis. Intrauterine pleural drainage was performed without improvement of the condition. Since maternal symptoms worsened, a caesarean section was performed at 34 weeks with delivery of a live hydropic girl who died after 17 hours. Maternal symptoms decreased four days after delivery with full recovery two weeks post-partum.
