Objectives: To evaluate the influence of fetoscopic laser therapy on fetal cardiac size in monochorionic twins complicated by twin-twin transfusion syndrome (TTTS). Methods: In a longitudinal, prospective study, we assessed fetal cardiac size sonographically in monochorionic diamniotic twins with TTTS treated by laser therapy and in monochorionic twins without TTTS. The fetal cardiothoracic ratio (cardiac circumference divided by thoracic circumference) of TTTS twins was determined within 24 h before, 12-24 h after and 1 week after laser treatment, and from then on every 2-4 weeks until birth. TTTS twins were classified into Quintero Stages 1-2 (n = 18) and Stages 3-4 (n = 16), and measurements were compared with biweekly measurements of non-TTTS monochorionic twins matched for gestational age (n = 38). Cardiomegaly was defined as a cardiothoracic ratio above the 97.5th percentile. Results: Before laser treatment, cardiomegaly was observed in 44% (8/18) and 50% (8/16) of recipients in Quintero Stages 1-2 and Stages 3-4, respectively. Cardiomegaly occurred in none of the donors before treatment. After laser treatment, cardiomegaly was observed in 76% (13/17) and 50% (7/14) of recipients in Stages 1-2 and Stages 3-4, respectively, and in 17% (3/18) and 13% (2/15) of donors in Stages 1-2 and Stages 3-4, respectively. Cardiomegaly was present in 18% (7/38) and 8% (2/25) of non-TTTS monochorionic twins and singletons. After laser therapy, the cardiothoracic ratio of recipients in Stages 1-2 and Stages 3-4 was not significantly changed (P = 0.34 and P = 0.67, respectively). The cardiothoracic ratio of donors in Stages 1-2 and Stages 3-4 was increased compared with that before laser therapy (P = 0.0002 and P = 0.005, respectively). Cardiothoracic ratios of non-TTTS monochorionic twins were not significantly different from our reference range in singletons throughout gestation, and were smaller than those in both recipients and donors after laser therapy. Conclusions: TTTS recipients show cardiomegaly before as well as after fetoscopic laser therapy for TTTS. Donors develop cardiomegaly only after laser treatment. Our findings emphasize the significant effect of TTTS and fetoscopic laser therapy on the fetal heart of both recipient and donor twins. [ABSTRACT FROM AUTHOR]

Objective To describe the outcome of pregnancies with fetal and neonatal alloimmune thrombocytopenia (FNAIT) in relation to the invasiveness of the management protocol. Design Retrospective analysis of prospectively collected data from a national cohort. Setting Leiden University Medical Centre, the national centre for management of severe red cell and platelet alloimmunisation in pregnancy. Population Ninety-eight pregnancies in 85 women with FNAIT having a previous child with thrombocytopenia with ( n= 16) or without ( n= 82) an intracranial haemorrhage (ICH). Methods Our management protocol evolved over time from (1) serial fetal blood samplings (FBS) and platelet transfusion ( n= 13) via (2) combined FBS with maternal intravenous immunoglobulins ( n= 33) to (3) completely noninvasive treatment with immunoglobulins only ( n= 52 pregnancies, resulting in 53 neonates). Perinatal outcome was assessed according to the three types of management. Main outcome measures Occurrence of ICH, perinatal survival, gestational age at birth and complications of FBS. Results All but one of 98 pregnancies ended in a live birth; none of the neonates had an ICH. The median gestational age at birth was 37 weeks (range 32–40). In groups 1 and 2, three emergency caesarean sections were performed after complicated FBS, resulting in two healthy babies and one neonatal death. Conclusion Noninvasive antenatal management of pregnancies complicated by FNAIT appears to be both effective and safe. [ABSTRACT FROM AUTHOR]

OBJECTIVE: The purpose of this study was to establish the true procedure-related complication rate of intrauterine transfusion therapy. STUDY DESIGN: A cohort study of 254 fetuses treated with 740 intrauterine blood transfusions for red-cell alloimmunization in a single center in the years 1988 to 2001. Our database was searched for perinatal deaths, emergency deliveries, infections, and preterm rupture of membranes associated with intrauterine blood transfusion. Complications were categorized by two independent obstetricians as procedure-related (PR) or not procedure-related (NPR). Logistic regression analysis was used to identify risk factors for complications. RESULTS: Overall survival was 225/254 (89%). Fetal death occurred in 19 cases (7 PR) and neonatal death in 10 cases (5 PR). There were two cases of intrauterine infection with Escherichia coli (both PR) and two other cases of preterm premature rupture of membranes (1 PR) within a week of a procedure. Emergency delivery after a transfusion was performed in 18 pregnancies (15 PR). The total PR complication rate was 3.1%, resulting in an overall PR loss rate of 1.6% per procedure. Arterial puncture, transamniotic cord puncture, refraining from fetal paralysis, and advancing gestational age were associated with the occurrence of PR complications. CONCLUSION: Our study shows that intrauterine transfusion is a safe procedure, with a relatively low PR perinatal loss rate. Arterial puncture and transamniotic cord needling carry a high risk for serious complications, whereas fetal paralysis improves the safety of the procedure. This information on risks of intrauterine transfusion therapy may help to further improve the safety of intrauterine transfusions. Data on complication rates of intrauterine transfusions are essential in counseling patients. [ABSTRACT FROM AUTHOR]

BACKGROUND: Although there is much debate about eating and drinking during labor, little scientific data about its influence on the course of labor exist. In The Netherlands, most midwives and obstetricians allow women to eat and drink during normal labor. The objective of this study was to examine whether or not women were actively advised to eat and drink and if this advice affected eating and drinking behavior. METHODS: A randomly selected group of midwives and obstetricians from across The Netherlands identified 211 consecutive nulliparous women to participate in the study. In a questionnaire with open-ended questions, women were asked after their delivery whether or not they were advised about eating and drinking during labor, and if so, about the nature of this advice and what they had consumed. Data were analyzed at the Leyenburg Hospital in The Hague. RESULTS: Sixty-six percent of the women were not given advice about eating and drinking during labor. Women who were given advice usually followed it. In the total group, 37 percent of the women had intake other than water and of these, 75 percent ate solid food. After adjusting for other prognostic factors, the incidence of an instrumental delivery due to a nonprogressing second stage was lower in women with caloric intake (13% vs 24%, p = 0.04). CONCLUSION: The study design did not enable us to draw conclusions about the cause and effect between caloric intake and labor progress. Scientific data with respect to the giving of evidence-based advice about eating and drinking during labor are lacking. Should such advice become available, women are likely to follow it.

Background: Pregnancies complicated by Rh alloimmunization have been evaluated with the use of serial invasive amniocentesis to determine bilirubin levels by measuring in the amniotic fluid the change in optical density at a wavelength of 450 nm (DeltaOD450); however, this procedure carries risks. Noninvasive Doppler ultrasonographic measurement of the peak velocity of systolic blood flow in the middle cerebral artery also predicts severe fetal anemia, but this test has not been rigorously evaluated in comparison with amniotic-fluid DeltaOD450.Methods: We performed a prospective, international, multicenter study including women with RhD-, Rhc-, RhE-, or Fy(a)-alloimmunized pregnancies with indirect antiglobulin titers of at least 1:64 and antigen-positive fetuses to assess whether Doppler ultrasonographic measurement of the peak systolic velocity of blood flow in the middle cerebral artery was at least as sensitive and accurate as measurement of amniotic-fluid DeltaOD450 for diagnosing severe fetal anemia. The results of the two tests were compared with the incidence of fetal anemia, as determined by measurement of hemoglobin levels in fetal blood.Results: Of 165 fetuses, 74 had severe anemia. For the detection of severe fetal anemia, Doppler ultrasonography of the middle cerebral artery had a sensitivity of 88 percent (95 percent confidence interval, 78 to 93 percent), a specificity of 82 percent (95 percent confidence interval, 73 to 89 percent), and an accuracy of 85 percent (95 percent confidence interval, 79 to 90 percent). Amniotic-fluid DeltaOD450 had a sensitivity of 76 percent (95 percent confidence interval, 65 to 84 percent), a specificity of 77 percent (95 percent confidence interval, 67 to 84 percent), and an accuracy of 76 percent (95 percent confidence interval, 69 to 82 percent). Doppler ultrasonography was more sensitive, by 12 percentage points (95 percent confidence interval, 0.3 to 24.0), and more accurate, by 9 percentage points (95 percent confidence interval, 1.1 to 15.9), than measurement of amniotic-fluid DeltaOD450.Conclusions: Doppler measurement of the peak velocity of systolic blood flow in the middle cerebral artery can safely replace invasive testing in the management of Rh-alloimmunized pregnancies.

Objectives: Determine the eclampsia prevalence and factors associated with eclampsia and recurrent seizures in Suriname and evaluate quality-of-care indicator 'magnesium sulfate (MgSO4) coverage'., Study Design: A two-year prospective nationwide cohort study was conducted in Suriname and included women with eclampsia at home or in a healthcare facility., Main Outcome Measures: We calculated the prevalence by the number of live births obtained from vital registration. Risk factor denominator data concerned hospital births. Descriptive statistics and multivariate regression analysis were performed., Results: Seventy-two women with eclampsia (37/10.000 live births) were identified, including two maternal deaths (case-fatality 2.8%). Nulliparity, African-descent and adolescence were associated with eclampsia. Adolescents with eclampsia had significantly lower BPs (150/100 mmHg) than adult women (168/105 mmHg). The first seizure occurred antepartum in 54% (n = 39/72), intrapartum in 19% (n = 14/72) and postpartum in 26% (n = 19/72). Recurrent seizures were observed in 60% (n = 43/72). MgSO4 was administered to 99% (n = 69/70) of women; however 26% received no loading dosage and, in 22% of cases MgSO4 duration was <24 h, i.e. guideline adherence existed in only 43%. MgSO4 was ceased during CS in all women (n = 40). Stable BP was achieved before CS in 46%. The median seizure-to-delivery interval was 27 h, and ranged from four to 36 h., Conclusion: Solely 'MgSO4 coverage' is not a reliable quality-of-care indicator, as it conceals inadequate MgSO4 dosage and timing, discontinuation during CS, stabilization before delivery, and seizure-to-delivery interval. These other quality-of-care indicators need attention from the international community in order to reduce the prevalence of eclampsia., (Copyright © 2020 The Author(s). Published by Elsevier B.V.

Background: Obstetric guidelines are useful to improve the quality of care. Availability of international guidelines has rapidly increased, however the contextualization to enhance feasibility of implementation in health facilities in low and middle-income settings has only been described in literature in a few instances. This study describes the approach and lessons learned from the 'bottom-up' development process of context-tailored national obstetric guidelines in middle-income country Suriname., Methods: Local obstetric health care providers initiated the guideline development process in Suriname in August 2016 for two common obstetric conditions: hypertensive disorders of pregnancy (HDP) and post partum haemorrhage (PPH)., Results: The process consisted of six steps: (1) determination of how and why women died, (2) interviews and observations of local clinical practice, (3) review of international guidelines, (4) development of a primary set of guidelines, (5) initiation of a national discussion on the guidelines content and (6) establishment of the final guidelines based on consensus. Maternal enquiry of HDP- and PPH-related maternal deaths revealed substandard care in 90 and 95% of cases, respectively. An assessment of the management through interviews and labour observations identified gaps in quality of the provided care and large discrepancies in the management of HDP and PPH between the hospitals. International recommendations were considered unfeasible and were inconsistent when compared to each other. Local health care providers and stakeholders convened to create national context-tailored guidelines based on adapted international recommendations. The guidelines were developed within four months and locally implemented., Conclusion: Development of national context-tailored guidelines is achievable in a middle-income country when using a 'bottom-up' approach that involves all obstetric health care providers and stakeholders in the earliest phase. We hope the descriptive process of guideline development is helpful for other countries in need of nationwide guidelines.

Background: Numerous RHD variant genes affect the expression of D on the red blood cell surface. In Suriname, 4.3% of pregnant women were D-, ranging from virtually zero to 7% among ethnic groups. Characterization of RHD variants, which are associated with a variable potential to induce anti-D, is of practical clinical importance especially in case of limited access to preventive measures. Here we report on the occurrence of RHD variant genes in Surinamese serologically D- pregnant women and their D- newborns from different ethnic groups., Study Design and Methods: The RheSuN study is a cross-sectional cohort study in D- pregnant women and their newborns, who visited hospitals in Paramaribo, Suriname, during routine pregnancy care. The presence of RHD variants was investigated using quantitative polymerase chain reaction targeting RHD Exons 5 and 7 and RH-multiplex ligation-dependent probe amplification., Results: Seven RHD variant genes were detected in 35 of 84 women and four RHD variant genes in 15 of 36 newborns. The RHD*03 N.01 and RHD*08 N.01 variants represented 87% of a total of 62 variant genes. Variants were comparably frequent among ethnicities. In four cases genotyping would have changed anti-D prophylaxis policy: one woman with a RHD*01EL.01 variant, not associated with anti-D formation and three D- newborns with RHD*09.01 and RHD*09.03.01 variants, potentially capable of inducing anti-D., Conclusion: RHD variants at risk for anti-D are common among serologic D- individuals from African descent in Suriname. While genotyping D- women has limited added value, it may be considered in newborns from D- women., (© 2019 AABB.)

Background: Sepsis was the main cause of maternal mortality in Suriname, a middle-income country. Objective of this study was to perform a qualitative analysis of the clinical and management aspects of sepsis-related maternal deaths with a focus on the 'golden hour' principle of antibiotic therapy., Methods: A nationwide reproductive age mortality survey was performed from 2010 to 2014 to identify and audit all maternal deaths in Suriname. All sepsis-related deaths were reviewed by a local expert committee to assess socio-demographic characteristics, clinical aspects and substandard care., Results: Of all 65 maternal deaths in Suriname 29 (45%) were sepsis-related. These women were mostly of low socio-economic class (n = 23, 82%), of Maroon ethnicity (n = 14, 48%) and most deaths occurred postpartum (n = 21, 72%). Underlying causes were pneumonia (n = 14, 48%), wound infections (n = 3, 10%) and endometritis (n = 3, 10%). Bacterial growth was detected in 10 (50%) of the 20 available blood cultures. None of the women with sepsis as underlying cause of death received antibiotic treatment within the first hour, although most women fulfilled the diagnostic criteria of sepsis upon admission. In 27 (93%) of the 29 women from which sufficient information was available, substandard care factors were identified: delay in monitoring in 16 (59%) women, in diagnosis in 17 (63%) and in treatment in 21 (78%)., Conclusion: In Suriname, a middle-income country, maternal mortality could be reduced by improving early recognition and timely diagnosis of sepsis, vital signs monitoring and immediate antibiotic infusion (within the golden hour)., Competing Interests: The authors have declared that no competing interests exist.

Background: In low-resource countries, screening for D antibodies to detect pregnancies at risk for hemolytic disease of the newborn is not routine practice. Retrospective data showed that 5.5% of Surinamese newborns of D-negative women had a positive direct antiglobulin test (DAT), indicating the presence of maternal antibodies against fetal antigens. Here, the frequency and clinical relevance of DAT positivity is evaluated., Study Design and Methods: Between April 2015 and June 2016, an observational, multicenter cohort study was undertaken among Surinamese newborns born to D-negative women. In newborns, the DAT was performed, and clinical outcomes between DAT-negative and DAT-positive newborns were compared., Results: Of the 232 evaluable newborns, 19 (8.2%) had a positive DAT, of which 11 of 15 antibody-tested newborns had D antibodies. DAT-positive newborns had lower hemoglobin levels (p = 0.02) and a trend toward higher bilirubin concentrations (p = 0.09) in the first days of life compared with DAT-negative newborns. DAT-positive newborns were admitted more frequently (p = 0.02), needed phototherapy treatment almost four times as often as DAT-negative newborns (26% vs. 7%; p = 0.008), and therapy took 2 days longer (p = 0.01). Exchange transfusions were performed in two newborns with D antibodies, both complicated with sepsis. The hospital stay was 2.5 days longer for DAT-positive newborns (p = 0.007). Overall, the prevalence of hemolytic disease of the newborn requiring treatment was 2.2% among the whole cohort of newborns., Conclusion: We found a high prevalence of DAT positivity with substantial need for hyperbilirubinemia treatment in newborns in Suriname. These results stress the necessity for better management procedures in D-negative women., (© 2017 AABB.)

Background: Maternal antibodies against the D antigen are the most common cause of severe hemolytic disease of the fetus and newborn (HDFN). In high-income countries, the risk of D immunization has been reduced by routine antenatal and postpartum administration of RhIG from 13% to less than 0.5%. In less-resourced countries, such as Suriname, red blood cell (RBC) antibody screening during pregnancy and prophylactic RhIG administration are not routine. Accurate data on D immunization risk is not available. In the RheSuN (Rhesus Surinamese Neonates) study, the prevalence and the hemolytic potential of maternal D antibodies were investigated., Study Design and Methods: A multicenter cross-sectional study in four major hospitals in Paramaribo, Suriname, covering 90% of approximately 10,000 births yearly in Suriname. Included were D- pregnant women of various ethnicities seeking routine prenatal care and/or their newborns., Results: D antibodies were detected in 19 of 214 D- pregnancies (8.9%; 95% confidence interval, 5.1%-12.7%), in 2.0% of primigravid and 11.7% of multigravid women. The direct antiglobulin test was positive in 11 of 13 tested D+ newborns. Determination of D antibody titers and antibody-dependent cell mediated cytotoxicity (ADCC) assay revealed three newborns at high risk for HDFN (ADCC > 50%)., Conclusion: D immunization risk in Suriname women is comparable to the pre-anti-D prophylaxis era in high-income countries. Recommended is free-of-charge routine RBC antibody screening and prophylactic RhIG administration for women at risk for D antibody formation as part of standard of ante- and postnatal care., (© 2017 AABB.)

Background: The fifth Millennium Development Goal (MDG-5) aimed to improve maternal health, targeting a maternal mortality ratio (MMR) reduction of 75% between 1990 and 2015. The objective of this study was to identify all maternal deaths in Suriname, determine the extent of underreporting, estimate the reduction, audit the maternal deaths and assess underlying causes and substandard care factors., Methods: A reproductive age mortality survey was conducted in Suriname (South-American upper-middle income country) between 2010 and 2014 to identify all maternal deaths in the country. MMR was compared to vital statistics and a previous confidential enquiry from 1991 to 1993 with a MMR 226. A maternal mortality committee audited the maternal deaths and identified underlying causes and substandard care factors., Results: In the study period 65 maternal deaths were identified in 50,051 live births, indicating a MMR of 130 per 100.000 live births and implicating a 42% reduction of maternal deaths in the past 25 years. Vital registration indicated a MMR of 96, which marks underreporting of 26%. Maternal deaths mostly occurred in the urban hospitals (84%) and the causes were classified as direct (63%), indirect (32%) or unspecified (5%). Major underlying causes were obstetric and non-obstetric sepsis (27%) and haemorrhage (20%). Substandard care factors (95%) were mostly health professional related (80%) due to delay in diagnosis (59%), delay or wrong treatment (78%) or inadequate monitoring (59%). Substandard care factors most likely led to death in 47% of the cases., Conclusion: Despite the reduction in maternal mortality, Suriname did not reach MDG-5 in 2015. Steps to reach the Sustainable Development Goal in 2030 (MMR ≤ 70 per 100.000 live births) and eliminate preventable deaths include improving data surveillance, installing a maternal death review committee, and implementing national guidelines for prevention and management of major complications of pregnancy, childbirth and puerperium.
