Xu Q, Li M, Wang X, Lu H, Zou W. Dichorionic triamniotic triplets after two blastocysts transfer underwent multifetal pregnancy reduction: two case reports and literature review. BMC Womens Health 2024; 24:492. [PMID: 39237895 PMCID: PMC11375843 DOI: 10.1186/s12905-024-03324-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2023] [Accepted: 08/20/2024] [Indexed: 09/07/2024] Open
Abstract
BACKGROUND The increase in the rate of multiple pregnancies in clinical practice is associated with assisted reproductive technology (ART). Given the high risk of dichorionic triamniotic (DCTA) triplet pregnancies, reducing DCTA triplet pregnancies to twin or singleton pregnancies is often beneficial. CASE PRESENTATION This article reports on two cases of DCTA triplet pregnancies resulting from two blastocyst transfers. Given the high risk of complications such as twin-to-twin transfusion syndrome (TTTS) in monochorionic diamniotic (MCDA) twin pregnancies, patients have a strong desire to preserve the dichorionic diamniotic (DCDA) twins. Multifetal pregnancy reduction (MFPR) was performed in both cases to continue the pregnancy with DCDA twins by reducing one of the MCDA twins. Both of the pregnant women in this report eventually gave birth to healthy twins at 37 weeks. CONCLUSIONS For infertile couples with multiple pregnancies but with a strong desire to remain the DCDA twins, our report suggests that reducing DCTA triplets to DCDA twin pregnancies may be an option based on clinical operability and assessment of surgical difficulty.

Considering multifetal pregnancy reduction in triplet pregnancies: do we forget the emotional impact on fathers? A qualitative study from The Netherlands. Hum Reprod 2024; 39:569-577. [PMID: 38199783 PMCID: PMC10905497 DOI: 10.1093/humrep/dead275] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2023] [Revised: 12/12/2023] [Indexed: 01/12/2024] Open
Abstract
STUDY QUESTION What factors influence the decision-making process of fathers regarding multifetal pregnancy reduction or maintaining a triplet pregnancy, and how do these decisions impact their psychological well-being? SUMMARY ANSWER For fathers, the emotional impact of multifetal pregnancy reduction or caring for triplets is extensive and requires careful consideration. WHAT IS KNOWN ALREADY Multifetal pregnancy reduction is a medical procedure with the purpose to reduce the number of fetuses to improve chances of a healthy outcome for both the remaining fetus(es) and the mother, either for medical reasons or social considerations. Aspects of the decision whether to perform multifetal pregnancy reduction have been rarely investigated, and the impact on fathers is unknown. STUDY DESIGN, SIZE, DURATION Qualitative study with semi-structured interviews between October 2021 and February 2023. PARTICIPANTS/MATERIALS, SETTING, METHODS Fathers either after multifetal pregnancy reduction from triplet to twin or singleton pregnancy or ongoing triplet pregnancies 1-6 years after the decision were included. The interview schedule was designed to explore key aspects related to (i) the decision-making process whether to perform multifetal pregnancy reduction and (ii) the emotional aspects and psychological impact of the decision. Thematic analysis was used to identify patterns and trends in the father's data. The process involved familiarization with the data, defining and naming themes, and producing a final report. This study was a collaboration between a regional secondary hospital (OLVG) and a tertiary care hospital (Amsterdam University Medical Center, Amsterdam UMC), both situated in Amsterdam, The Netherlands. MAIN RESULTS AND THE ROLE OF CHANCE Data saturation was achieved after 12 interviews. Five main themes were identified: (i) initial responses and emotional complexity, (ii) experiencing disparities in counselling quality and post-decision care, (iii) personal influences on the decision journey, (iv) navigating parenthood: choices, challenges, and emotional adaptation, and (v) shared wisdom and lessons. For fathers, the decision whether to maintain or reduce a triplet pregnancy is complex, in which medical, psychological but mainly social factors play an important role. In terms of psychological consequences after the decision, this study found that fathers after multifetal pregnancy reduction often struggled with difficult emotions towards the decision; some expressed feelings of doubt or regret and were still processing these emotions. Several fathers after an ongoing triplet had experienced a period of severe stress in the first years after the pregnancy, with major consequences for their mental health. Help in emotional processing was not offered to any of the fathers after the decision or birth. LIMITATION, REASONS FOR CAUTION While our study focuses on the multifetal pregnancy reduction process in the Amsterdam region, we recognize the importance of further investigation into how this process may vary across different regions in The Netherlands and internationally. We acknowledge the potential of selection bias, as fathers with more positive experiences might have been more willing to participate. Caution is needed in interpreting the role of the mother in the recruitment process. Additionally, the time span of 1-6 years between the decision and the interviews may have influenced emotional processing and introduced potential reporting bias. WIDER IMPLICATIONS OF THE FINDINGS The emotional impact of multifetal pregnancy reduction or caring for triplets is significant, emphasizing the need for awareness among caregivers regarding the emotional challenges faced by fathers. A guided trajectory might optimize the decision-making and primarily facilitate the provision of appropriate care thereafter to optimize outcomes around decisions with potential traumatic implications. STUDY FUNDING/COMPETING INTEREST(S) This study received no funding. The authors have no conflicts of interest to declare. TRIAL REGISTRATION NUMBER N/A.

J Matern Fetal Neonatal Med 2023; 36:2245530. [PMID: 37558283 DOI: 10.1080/14767058.2023.2245530] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2023] [Revised: 04/04/2023] [Accepted: 08/02/2023] [Indexed: 08/11/2023]
Abstract
OBJECTIVE To compare neonatal outcomes between multiples and singletons among very low birth weight infants, this was a prospective cohort study that was conducted by collecting data registered in the Korean Neonatal Network database. METHODS From January 2013 to December 2016, there were 8265 infants in the Korean Neonatal Network database, and 2958 of them were from multiples. Among them, 2636 infants were twins, 308 infants were triplets, and 14 infants were quadruplets. Maternal and neonatal variables including and mortality major morbidity were compared. Finally, the predicted rates of major morbidity between singletons and multiples. RESULTS Multiples had higher gestational age, birth weight, Apgar score at 5 min, rates of cesarean section and artificial reproductive technology but lower maternal hypertension, oligohydramnios, chorioamnionitis rates and Clinical Risk Index for Babies scores II without base excess than the singletons. In univariate analysis, multiples had a lower incidence of respiratory distress syndrome, bronchopulmonary dysplasia, and sepsis. The mortality rate was not significantly different for overall gestational ages except for those born at ≤26 weeks of gestation. In multivariate logistic analysis, the incidences of intraventricular hemorrhage (grade ≥3), and retinopathy of prematurity requiring treatment were significantly higher than the singletons. CONCLUSIONS Mortality was not significantly different between multiples and singletons according to overall gestational age, except for multiples born at ≤26 weeks. A significant higher risk of intraventricular hemorrhage and retinopathy of prematurity requiring treatment was found in multiples. A new strategy to improve the mortality of immature multiples born at ≤26 weeks of gestation should be developed.

Maternal, Perinatal and Neonatal Outcomes of Triplet Pregnancies According to Chorionicity: A Systematic Review of the Literature and Meta-Analysis. J Clin Med 2022; 11:jcm11071871. [PMID: 35407479 PMCID: PMC8999732 DOI: 10.3390/jcm11071871] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2022] [Revised: 03/18/2022] [Accepted: 03/21/2022] [Indexed: 11/17/2022] Open
Abstract
Triplet pregnancies are rare events that affect approximately 93 in 100,000 deliveries in the world, especially due to the increased use of assisted reproductive techniques and older maternal age. Triplet pregnancies are associated with a higher risk of fetal and maternal morbidity and mortality compared to twins and singletons. Chorionicity has been proposed as a major determinant of perinatal and maternal outcomes in triplet pregnancies, although further evidence is needed to clarify the extent and real influence of this factor. Thus, the aim of this study was to conduct a systematic review of the literature and a meta-analysis of the maternal and perinatal outcomes of triplet pregnancies, evaluating how chorionicity may influence these results. A total of 46 studies with 43,653 triplet pregnancies and 128,145 live births were included. Among the main results of our study, we found a broad spectrum of fetal and maternal complications, especially in the group of monochorionic and dichorionic pregnancies. Risk of admission to NICU, respiratory distress, sepsis, necrotizing enterocolitis, perinatal and intrauterine mortality were all found to be higher in non-TCTA pregnancies than in TCTA pregnancies. To date, our meta-analysis includes the largest population sample and number of studies conducted in this field, evaluating a wide variety of outcome measures. The heterogeneity and retrospective design of the studies included in our research represent the main limitations of this review. More evidence is needed to fully assess outcome measures that could not be studied in this review due to scarcity of publications or insufficient sample size.

Abstract
BACKGROUND Conjoined twins are a rare and serious complication of monochorionic twins. The total incidence is 1.5 per 100,000 births, and about 50% are liveborn. Prenatal screening and diagnosis of conjoined twins is usually performed by ultrasonography. Magnetic resonance imaging can be used to assist in the diagnosis if necessary. Conjoined twins in dichorionic diamniotic triplet pregnancy are extremely rare. CASE PRESENTATION We reported three cases of dichorionic diamniotic triplet pregnancy with conjoined twins. Due to the poor prognosis of conjoined twins evaluated by multidisciplinary teams, selective termination of conjoined twins was performed in three cases. In case 1, selective reduction of the conjoined twins was performed at 16 gestational weeks, and a healthy female baby weighing 3270 g was delivered at 37 weeks. In case 2, the conjoined twins were selectively terminated at 17 weeks of gestation, and a healthy female baby weighing 2760 g was delivered at 37 weeks and 4 days. In case 3, the conjoined twins were selectively terminated at 15 weeks and 2 days, and a healthy female baby weighing 2450 g was delivered at 33 weeks and 6 days. The babies of all three cases were followed up and are in good health. CONCLUSION(S) Surgical separation is the only treatment for conjoined twins after birth. Early determination of chorionicity and antenatal diagnosis of conjoined twins in triplet gestations are critical for individualized management options and the prognosis of normal triplets. Expecting parents should be extensively counseled by multidisciplinary teams. If there are limitations in successful separation after birth, early selective termination of the conjoined twins by intrathoracic injection of potassium chloride may be a procedure in dichorionic diamniotic triplet pregnancy to improve perinatal outcomes of the normal triplet.

Abstract
Background Monochorionic diamniotic triplet pregnancies are rare. Twin reversed arterial perfusion sequence in monochorionic triplet pregnancies is extremely rare, and it is associated with high perinatal morbidity and mortality rates in the “pump fetus.” Case presentation We reported a case of monochorionic diamniotic triplet pregnancy with twin reversed arterial perfusion sequence, including two acardiac fetuses sharing a single amniotic sac and a normal fetus in another amniotic sac. Due to rapid growth of the acardiac fetuses, intrafetal laser therapy was performed in both of them under ultrasound guidance at 15 weeks +5 days. Subsequently, regular and careful antenatal care including fetal ultrasonography and doppler and fetal echocardiography was conducted. At 37 weeks +4 days, a healthy female baby weighing 2510 g was delivered. The baby was followed up and now at 11 months old is in good health. Conclusions Twin reversed arterial perfusion sequence in monochorionic triplet pregnancy should be diagnosed early by ultrasound imaging during pregnancy. Individualized management should be based on clinical conditions to improve the perinatal outcome of the pump twin. Intrafetal laser therapy could be an alternative procedure when intrauterine intervention is required.

Abstract
Preeclampsia (PE) is a complication of pregnancy characterized by hypertension (HTN-Preg), and often proteinuria. If not managed promptly, PE could lead to eclampsia and seizures. PE could also lead to intrauterine growth restriction (IUGR) and prematurity at birth. Although PE is a major cause of maternal and fetal morbidity and mortality, the underlying mechanisms are unclear. Also, there is a wide variability in the incidence of PE, ranging between 2 and 8% of pregnancies in the Eastern, Western and Developing world, suggesting regional differences in the risk factors and predictors of the pregnancy-related disorder. Several demographic, genetic, dietary and environmental factors, as well as maternal circulating biomarkers have been associated with PE. Demographic factors such as maternal race and ethnicity could play a role in PE. Specific genetic polymorphisms have been identified in PE. Maternal age, parity, education and socioeconomic status could be involved in PE. Dietary fat, protein, calcium and vitamins, body weight, and environmental factors including climate changes and air pollutants could also play a role in PE. Several circulating cytoactive factors including anti-angiogenic factors and cytokines have also been associated with PE. Traditional midwifery care is a common practice in local maternity care units, while advanced perinatal care and new diagnostic tools such as uterine artery Doppler velocimetry have been useful in predicting early PE in major medical centers. These PE risk factors, early predictors and diagnostic tools vary vastly in different regions of the Eastern, Western and Developing world. Further understanding of the differences in the demographic, genetic, dietary and environmental factors among pregnant women in different world regions should help in designing a region-specific cluster of risk factors and predictors of PE, and in turn provide better guidance for region-specific tools for early detection and management of PE.

Abstract
Experience managing triplet pregnancies has increased over the past few decades as the incidence has changed related to assisted reproductive practices. Physicians caring for women carrying triplets cannot predict an individual outcome or pregnancy course but must educate patients about the challenges related to these high risk pregnancies. Obstetric providers can describe the wide range of risks associated with triplet gestations, and the general plan for management, but ultimately parents must make decisions with potentially lifelong consequences. Here, we present the diagnostic criteria, common complications, and management options for triplet pregnancies, to help obstetricians counsel patients on the medical and psychosocial consequences of triplet pregnancy, potential complications, and multifetal reduction.

Abstract
Multiple gestations are commonly encountered in both high-risk and low-risk pregnancies and, since the advent of assisted reproductive technologies in the 1980s, the numbers of multiple gestations have grown rapidly. Thus, an understanding of both the maternal and fetal risks associated with multiple gestations should be central to all obstetric practice. The ability to foresee issues and the know how to respond to the complications that develop are central to the correct management of these pregnant women. For some, appropriate management may include referral to a specialist maternal and fetal medicine physician or, in some cases, to a specialist fetal center. The present review provides a comprehensive and simplified overview of multiple gestations, including incidence, diagnosis, genetic considerations, complications (both general and specific to multiple gestation subtypes), and delivery management. It is essential that providers recognize the high-risk and specific complications that may affect a multiple gestation in order to provide the highest possible level of care for these pregnant women.

Abstract
Background: Over the last decades, there has been a substantial increase in the incidence of higher-order multiple gestations. Twin pregnancies are associated with an increased risk of gestational diabetes mellitus (GDM). The literature on GDM rates in triplet pregnancies is scarce. Methods: A retrospective cohort study was performed to assess the prevalence of GDM in women with a triplet pregnancy. GDM was defined through an abnormal oral glucose tolerance test (OGTT). A meta-analysis of GDM prevalence was also carried out. Results: A cohort of 60 women was included in the analysis. Of these, 19 (31.7%) were diagnosed with GDM. There were no differences in pregnancy outcomes between women with and without GDM. In the meta-analysis of 12 studies, which used a sound GDM definition, an estimated pooled prevalence of 12.4% (95% confidence interval: 6.9–19.1%) was found. In a leave-one-out sensitivity analysis, the estimated GDM prevalence ranged from 10.7% to 14.1%. Conclusion: The rate of GDM seems increased in women with triplets compared to singleton pregnancies. However, GDM did not impact short-term pregnancy outcomes.

Pregnancy outcomes of dichorionic triamniotic triplet pregnancies after in vitro fertilization-embryo transfer: multifoetal pregnancy reduction versus expectant management. BMC Pregnancy Childbirth 2020; 20:165. [PMID: 32178634 PMCID: PMC7077126 DOI: 10.1186/s12884-020-2815-4] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/23/2019] [Accepted: 02/17/2020] [Indexed: 11/25/2022] Open
Abstract
Background Trichorionic triplet pregnancy reduction to twin pregnancy is associated with a lower risk of preterm delivery but not with a lower risk of miscarriage. However, data on dichorionic triamniotic (DCTA) triplet pregnancy outcomes are lacking. This study aimed to compare the pregnancy outcomes of DCTA triplets conceived via in vitro fertilization-embryo transfer (IVF-ET) managed expectantly or reduced to a monochorionic (MC) singleton or monochorionic diamniotic (MCDA) twins at 11–13+ 6 gestational weeks. Methods Two hundred ninety-eight patients with DCTA triplets conceived via IVF-ET between 2012 and 2016 were retrospectively analysed. DCTA triplets with three live foetuses were reduced to a MC singleton (group A) or MCDA twins (group B) or underwent expectant management (group C). Each multifoetal pregnancy reduction (MFPR) was performed at 11–13+ 6 gestational weeks. Pregnancy outcomes in the 3 groups were compared. Results Eighty-four DCTA pregnancies were reduced to MC singleton pregnancies, 149 were reduced to MCDA pregnancies, and 65 were managed expectantly. There were no significant differences among groups A, B, and C in miscarriage rate (8.3 vs. 7.4 vs. 10.8%, respectively) and live birth rate (90.5 vs. 85.2 vs. 83.1%, respectively) (P > 0.05). Group A had significantly lower rates of preterm birth (8.3 vs. 84.6%; odds ratio (OR) 0.017, 95% confidence interval (CI) 0.006–0.046) and low birth weight (LBW; 9.2 vs. 93.2%; OR 0.007, 95% CI 0.003–0.020) than group C (P < 0.001). Group B had significantly lower preterm birth (47.0 vs. 84.6%; OR 0.161, 95% CI 0.076–0.340) and LBW rates (58.7 vs. 93.2%; OR 0.103, 95% CI 0.053–0.200) than group C (P < 0.001). Group A had significantly lower preterm birth (8.3 vs. 47.0%; OR 0.103, 95% CI 0.044–0.237; P < 0.001), LBW (9.2 vs. 58.7%; OR 0.071, 95% CI 0.032–0.162; P < 0.001) and perinatal death rates (1.3 vs. 9.1%; OR 0.132, 95% CI 0.018–0.991; P = 0.021) than group B. Conclusion The MFPR of DCTA triplets to singleton or MCDA pregnancies was associated with better pregnancy outcomes compared to expectant management. DCTA triplets reduced to singleton pregnancies had better perinatal outcomes than DCTA triplets reduced to MCDA pregnancies.

Abstract
Background Triplet pregnancies are associated with higher fetal morbidity and mortality rates as well as life-threatening maternal complications. Monochorionic diamniotic (MCDA) triplet pregnancies are very rare compared to other types of triplet pregnancies. Case presentation We report three cases of MCDA triplet pregnancies between January 2012 and December 2017. Two of these MCDA triplet pregnancies received regular and intensive prenatal care, were diagnosed by ultrasonography during the first trimester or early second trimester, and had good perinatal outcomes. The case with irregular perinatal care had poor outcomes, and the MCDA triplet pregnancy was diagnosed intrapartum. Conclusions The possibility of continuing an MCDA triplet pregnancy should be recognized. Early diagnosis, regular antenatal care, close prenatal monitoring, and sufficient communication are recommended to obtain better perinatal outcomes in MCDA triplet pregnancies.

Abstract
OBJECTIVE To describe obstetrical care and in-hospital outcomes in very preterm triplet pregnancies in a European multiregional cohort. METHODS Data from a prospective population-based study of very preterm births between 22 + 0 and 31 + 6 weeks of gestation in 19 regions from 11 European countries participating in the EPICE project in 2011/2012 were used to describe triplet pregnancies and compare them with twins and singletons. RESULTS Triplets constituted 1.1% of very preterm pregnancies (97/8851) and 3.3% of very preterm live births (258/7900); these percentages varied from 0% to 2.6% and 0% to 6% respectively across the regions. In-hospital mortality after live birth was 12.4% and did not differ significantly from singletons or twins or by birth order. However, 28.9% of mothers with a triplet pregnancy experienced at least one neonatal death. Ninety percent of live-born triplets were delivered by cesarean. Vaginal delivery was associated with an Apgar score of less than 7, but not with in-hospital mortality. CONCLUSIONS The prevalence of very preterm triplets varies across European regions. Most triplets were born by cesarean and those born vaginally had lower Apgar scores. Overall, in-hospital mortality after live birth was similar to singletons and twins.

Abstract
Objective This study was conducted to demonstrate the temporal trends in perinatal outcomes of triplet pregnancies over the last two decades. Methods The medical records of patients with triplet pregnancies at two Korean tertiary-care hospitals from 1992 to 2012 were retrospectively reviewed in regard to maternal and neonatal outcomes. The study was divided into two periods for analysis: period I (1992-2001) and period II (2003-2012). Results Over a 21-year period, 65 women with triplet pregnancies and 185 neonates were analyzed. Period II, when compared with period I, was associated with improved maternal outcomes, characterized by a decreased incidence of preeclampsia (31.8% vs. 2.3%, P=0.002) and anemia (68.2% vs. 30.2%, P=0.003) during pregnancy. Regarding neonatal aspects, the composite morbidity of period II was significantly decreased compared with that of period I, as assessed with a generalized estimating equation for logistic regression (26.2% vs. 8.1%, P=0.03). Multivariable analysis revealed that the gestational age at delivery and the period were significantly associated with the composite neonatal morbidity (P<0.001 and 0.007, respectively). Conclusion Improved neonatal morbidity was associated with a higher gestational age at delivery and with the more recent decade.

Abstract
A 35-year-old woman with membranoproliferative glomerulonephritis type I had quintuplet gestation after induced ovulation. Her serum creatinine level and estimated glomerular filtration rate were 0.86 mg/dL and 61.5 mL/min/1.73 m2 before pregnancy. Blood pressure was normal and urinary protein to creatinine ratio was 0.2 g/gCr. Prednisolone 10 mg on alternate-day administration was continued during pregnancy. At 10 weeks of gestation transvaginal selective embryo reduction was performed and five embryos were reduced to twins. Hypertension occurred at 20 weeks of gestation. She developed nephrotic syndrome and serum creatinine level increased to 1.29 mg/dL. Elective cesarean section was performed at 28 weeks of gestation and dichorionic diamniotic twins were born. After delivery blood pressure, serum creatinine level, estimated glomerular filtration rate and serum albumin level in their mother returned to baseline. Her twin infants were well at discharge from neonatal-intensive-care-unit. Incidence of multifetal pregnancies due to the improvement of assisted reproduction technologies and ovulation-inducing hormones has been increasing. Management for multifetal pregnancy in women with chronic kidney disease will be needed further.

Abstract
OBJECTIVE To assess the predictive value of sonographic cervical-length (CL) measurement in mid-gestation for spontaneous preterm birth (PTB) in asymptomatic triplet pregnancy. METHODS This was a retrospective study of asymptomatic triplet pregnancies followed at five Italian tertiary referral centers, between 2002 and 2015. CL was measured transvaginally between 18 and 24 weeks' gestation. Pregnancies with medically indicated PTB were excluded. Demographic and pregnancy characteristics of pregnancies complicated by PTB were analyzed and the distributions of CL measurements in these patients were calculated. Logistic regression analysis was performed to assess the association between CL and PTB, adjusted for confounders. Performance of CL measurement in prediction of PTB < 28, < 30 and < 32 weeks of gestation was assessed. RESULTS A total of 120 triplet pregnancies were included in the final analysis. Median CL was 35 (interquartile range (IQR), 29-40) mm measured at a median gestational age of 20 + 2 (IQR, 20 + 0 to 23 + 4) weeks. Overall, 23 (19.2%), 17 (14.2%) and eight (6.7%) patients had a CL < 25, < 20 and < 15 mm, respectively. Spontaneous PTB < 32 weeks occurred in 41 (34.2%) cases, < 30 weeks in 23 (19.2%) and < 28 weeks in 12 (10%) cases. CL < 15 mm was significantly more frequent in the group of patients who delivered < 28 (P = 0.03) and < 30 (P = 0.01) weeks' gestation, compared with those who delivered after 28 and after 30 weeks, respectively, while CL < 20 mm was more common in triplet pregnancies with delivery < 32 weeks compared with those delivered ≥ 32 weeks (P = 0.03). Logistic regression analysis was possible only for PTB < 32 weeks due to the small number of cases that delivered < 30 and < 28 weeks. After adjustment for confounders, CL was not significantly associated with PTB < 32 weeks (adjusted odds ratio, 0.97; 95% CI, 0.94-1.01). CL measurement had an area under the receiver-operating characteristics curve of 0.41 (95% CI, 0.20-0.62), 0.41 (95% CI, 0.26-0.56) and 0.42 (95% CI, 0.31-0.54) for the prediction of spontaneous PTB < 28, < 30 and < 32 weeks, respectively. CONCLUSION CL assessed in mid-gestation is a poor predictor of PTB < 28, < 30 and < 32 weeks' gestation in asymptomatic triplet pregnancy. Copyright © 2017 ISUOG. Published by John Wiley & Sons Ltd.

Abstract
STUDY QUESTION Is pregnancy outcome in triplet pregnancies improved with embryo reduction (ER) to twins compared to expectant management? SUMMARY ANSWER In trichorionic triplet pregnancies, ER to twins reduces the risk of preterm birth (<34 weeks) without significantly increasing the risk of miscarriage (<24 weeks), whereas in dichorionic triplet pregnancies, the results are inconclusive. WHAT IS KNOWN ALREADY Triplet pregnancies are associated with a high risk of miscarriage and preterm birth. ER can ameliorate these conditions in higher order multiple gestations but is still controversial in triplets. STUDY DESIGN, SIZE, DURATION This study aimed to conduct a systematic review, following the PRISMA guidelines, and critically appraise ER at 8-14 weeks of gestation in both trichorionic triamniotic (TCTA) and dichorionic triamniotic (DCTA) pregnancies. Selective ER to twins was compared with expectant management, focusing on the risks of miscarriage and preterm birth. The computerized database search was performed on 8 January 2017. Overall, from 25 citations of relevance, eight studies with a total of 249 DCTA and 1167 TCTA pregnancies fulfilled the inclusion criteria. PARTICIPANTS/MATERIALS, SETTING, METHODS A comprehensive computerized systematic literature search of all English language studies between 2000 and 2016 was performed in PubMed, EMBASE, Scopus, Evidence Based Medicine Reviews (Cochrane Database and Cochrane Central Register of Controlled Trials) and Google Scholar. Relevant article reference lists were hand searched. The management options were compared for rates of miscarriage <24 weeks and preterm birth <34 weeks. Only studies with both expectant management and ER to twins were included in the analysis. The quality of each individual article was critically appraised and appropriate statistical methods were used to extract results. MAIN RESULTS AND THE ROLE OF CHANCE In TCTA pregnancies managed expectantly (n = 501), the rates of miscarriage and preterm birth were 7.4 and 50.2%, respectively. Meta-analysis demonstrated that ER to twins in TCTA pregnancies (n = 666) was associated with a lower risk (17.3 versus 50.2%) of preterm birth (RR = 0.36, 95% CI: 0.28-0.48), whereas the risk of miscarriage (8.1% versus 7.4%) did not significantly increase (RR = 1.08, 95% CI: 0.58-1.98). In DCTA triplets managed expectantly (n = 200), the rates of miscarriage and preterm birth were 8.5 and 51.9%, respectively. Although the meta-analysis was inconclusive, it suggested that ER to twins in DCTA triplets, either of the foetus with a separate placenta (n = 15) or one of the monochorionic pair (n = 34), was neither significantly associated with an increased risk of miscarriage (8.5 versus 13.3%, P = 0.628 and RR = 1.22, 95% CI: 0.38-3.95, respectively) nor with a lower risk of preterm birth (51.9 versus 46.2%, P = 0.778 and RR = 0.5, 95% CI: 0.04-5.7, respectively). LIMITATIONS, REASONS FOR CAUTION No randomized controlled trials of ER versus expectant management in TCTA or DCTA pregnancies were identified from our literature search. We were able to include only a handful of papers with small sample sizes and suffering from bias, and non-English publications were missed. Irrespective of the strict inclusion and exclusion criteria, publication bias was evident. WIDER IMPLICATIONS OF THE FINDINGS The greatest strength of our systematic review is that, contrary to the existing literature, it only included studies with both the intervention and expectant arm. Our results are in agreement with current literature. In TCTA pregnancies, ER to twins is associated with a lower risk of preterm birth but is not associated with a higher risk of miscarriage. In the absence of a randomized trial, the data from systematic reviews appear to be the best existing evidence for counselling in the first trimester on the different options available. Finally, in DCTA pregnancies, indications exist that ER (of one of the MC pair) to twins could possibly reduce the risk of preterm birth without increasing the risk of miscarriage.

Abstract
Background Higher-order multiple (HOM) pregnancies are associated with increased incidences of pregnancy complications mainly abortions, pre-eclampsia, preterm delivery and fetal death. Multifetal reduction (MFR) during first trimester and subsequent delivery of twins can reduce pregnancy associated morbidities. This study was conducted to evaluate the maternal and fetal outcomes of MFR procedure in patients with HOMs those managed in a tertiary care hospital. Methods and Material It was a prospective observational study carried out in a tertiary care military hospital, India, and all women with higher-order multiples (triplets or more) conceived spontaneously or after infertility treatment (ovulation induction, intra-uterine insemination, or in vitro fertilization) during the 3-year period from Jan 2014 to Dec 2016 were included for MFR. Demographic and clinical data, and obstetric and neonatal outcomes were tabulated. Results The study included 32 HOM pregnancies which underwent MFR. 16% patients had pre-eclampsia and 12% patients had gestational diabetes. The study had 2 pregnancy losses before 24 weeks period of gestation (POG). 70% patients underwent cesarean delivery with mean gestational age of 35.5 weeks. Average birth weight of newborn was 1820 gm and 80% of them required NICU admission. Conclusion Favorable pregnancy outcomes can be achieved after multifetal reductions during first trimester in higher-order multiples, but the procedure is not totally safe.

Abstract
OBJECTIVES Tocompare maternal and neonatal complications in twin and triplet gestations at King Abdulaziz University Hospital, Jeddah, Saudi Arabia. Methods: Retrospective medical records of 165 women with 144 twin and 21 triplet pregnancies from 2004 to 2011 were analyzed. Comparisons were carried out for maternal complications, gestational age at birth, neonatal birth weight, and neonatal intensive care admission. Results: Most common complications were preterm birth (49%), gestational diabetes mellitus (13.3%), and premature rupture of membrane (4.8%). All triplet pregnancies and 42% twin pregnancies terminated in preterm birth. Gestational length was longer (p less than 0.001) in twin births (36.0 ± 3.05 weeks) than for triplet births (32 ± 3.81 weeks). Rates for in vitro fertilization, ovulation induction, and cesareans were higher in women with triplets than in those with twins. Neonatal intensive care unit (NICU) admission was higher (p less than 0.001) for triplets (76.2%) than for twins (23.6%). The mean weight of twins was 2333.83 ± 558.69 grams and triplets was 1553.41 ± 569.73 grams. Hyaline membrane disease, neonatal jaundice, and neonatal sepsis were most common neonatal complications. Conclusion: Neonates from triplet pregnancies were preterm, had low birth weight and needed more often NICU admission in comparison to those from twin pregnancies.

Abstract
Triplet and higher-order multiple pregnancies can carry increased fetal and maternal complications. Reports of triplet pregnancies after kidney transplant are scarce and have been associated with perinatal complications. Presence of diabetes in such cases worsens both fetal and maternal outcomes. Here, we present a triplet pregnancy in a kidney transplant recipient with diabetes. We also reviewed the literature for causes, prevalence, and outcomes in association with chronic kidney disease, kidney transplant, and diabetes mellitus. The patient, a 31-year-female who received a living-donor kidney transplant, had a first-time pregnancy 6 years after transplant. Pregnancy was complicated by gestational diabetes, preeclampsia, and miscarriage. She continued to have postpartum-impaired glucose tolerance. She became pregnant again after 6 months but required insulin therapy during her third trimester. Pregnancy was terminated by cesarean section for a viable small boy. Two years later, she had triplet pregnancy after ovulation induction with clomiphene. Glycemic control was maintained using intensive insulin therapy guided by frequent home blood glucose monitoring (HbA1c was 5.8% at 22 wk). Both gynecologic care and nephrologic care were carried out through outpatient follow-up. Pregnancy was complicated by hypertension and mild renal dysfunction without proteinuria and ended in elective premature cesarean section at 32 weeks of gestation. She had 3 male babies with low birth weights (1320, 1380, 1275 g), with the largest baby developing sepsis and requiring an intensive care unit stay and then incubator for 49 days. The other 2 required incubators for 36 days. Their weights after 22 months were 9, 16, and 11 kg. The mother is now normotensive with normal renal function and impaired glucose tolerance. Care of diabetic kidney recipients with triplet pregnancy constitutes a special challenge requiring a multispecialty skilled team to ensure the best outcome.

Abstract
Objectives: To compare pregnancy outcomes between high-order multiple pregnancies resulting from assisted reproductive technology (ART) reduced to twins and non-reduced pregnancies, and to evaluate indications for using ART. Methods: This is a descriptive retrospective review of women with high-order multiple pregnancies reduced to twin carried out at the Department of Obstetrics & Gynecology, King Faisal Specialist Hospital & Research Center, Riyadh, Saudi Arabia between December 2010 and December 2013. The control group consisted of subjects with twin pregnancies who received their fertility treatment at the same hospital during the same period. Results: One hundred and twelve women were included in this study. Of women reaching fetal viability, significantly more women delivered before the thirtieth week in the study group (50% versus 12%, p<0.004). Miscarriage/delivery prior to fetal viability, chorioamnionitis, and preterm premature rupture of membranes were statistically higher in the study group. A total of 83% of the miscarriages in the study group were in women carrying 4 or more fetuses initially, and 50% of women in the study group were multiparous with no clear indication for fertility treatment. Conclusion: Although fetal reduction is a safe procedure, it is associated with complications. Primary prevention of high-order multiple pregnancy is recommended.

[PMID: 26576487 DOI: 10.1016/j.ajog.2015.11.003] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/12/2015] [Revised: 10/14/2015] [Accepted: 11/05/2015] [Indexed: 11/25/2022]
Abstract
BACKGROUND Adverse neonatal outcomes in multiple pregnancies have been documented extensively, in particular those associated with the increased risk of preterm birth. Paradoxically, much less is known about adverse maternal events. The combined risk of severe acute maternal morbidity in multiple pregnancies has not been documented previously in any nationwide prospective study. OBJECTIVE The objective of the study was to assess the risk of severe acute maternal morbidity in multiple pregnancies in a high-income European country and identify possible risk indicators. STUDY DESIGN In a population-based cohort study including all 98 hospitals with a maternity unit in The Netherlands, pregnant women with severe acute maternal morbidity were included in the period Aug. 1, 2004, until Aug. 1, 2006. We calculated the incidence of severe acute maternal morbidity in multiple pregnancies in The Netherlands using The Netherlands Perinatal Registry. Relative risks (RR) of severe acute maternal morbidity in multiple pregnancies compared with singletons were calculated. To identify possible risk indicators, we also compared age, parity, method of conception, onset of labor, and mode of delivery for multiple pregnancies using The Netherlands Perinatal Registry as reference. RESULTS A total of 2552 cases of severe acute maternal morbidity were reported during the 2 year study period. Among 202 multiple pregnancies (8.0%), there were 197 twins (7.8%) and 5 triplets (0.2%). The overall incidence of severe acute maternal morbidity was 7.0 per 1000 deliveries and 6.5 and 28.0 per 1000 for singletons and multiple pregnancies, respectively. The relative risk of severe acute maternal morbidity compared with singleton pregnancies was 4.3 (95% confidence interval [CI], 3.7-5.0) and increased to 6.2 (95% CI 2.5-15.3) in triplet pregnancies. Risk indicators for developing severe acute maternal morbidity in women with multiple pregnancies were age of ≥ 40 years, (RR, 2.5 95% CI, 1.4-4.3), nulliparity (RR, 1.8, 95% CI, 1.4-2.4), use of assisted reproductive techniques (RR, 1.9, 95% CI, 1.4-2.5), and nonspontaneous onset of delivery (RR, 1.6, 95% CI, 1.2-2.1). No significant difference was found between mono- and dichorionic twins (RR, 0.8, 95% CI, 0.6-1.2). CONCLUSION Women with multiple pregnancies in The Netherlands have a more than 4 times elevated risk of sustaining severe acute maternal morbidity as compared with singletons.

Abstract
OBJECTIVE The objective of our study was to evaluate the prevalence of abnormal maternal echocardiographic findings in triplet pregnancies presenting with dyspnoea. STUDY DESIGN Between 2003 and 2013, patients' records of 96 triplet pregnancies at our department were analysed including maternal and fetal outcome, echocardiographic parameters and N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels. After exclusion of triplet pregnancies with fetal demise before 23 + 0 weeks, selective feticide or missing outcome data, the study population consisted of 60 triplet pregnancies. All women with dyspnoea underwent echocardiography and measurement of NT-proBNP. RESULTS Dyspnoea towards the end of pregnancy was observed in 13.3% (8/60) of all women with triplet pregnancies, and all of these women underwent echocardiography. The prevalence of abnormal echocardiographic findings in women with dyspnoea was 37.5% (3/8) with peripartum cardiomyopathy in one woman. Median serum NT-proBNP was significantly higher in women with abnormal echocardiographic findings compared with those without (1779 ng/ml, range 1045-6076 ng/ml vs 172 ng/ml, range 50-311 ng/ml; p < 0.001 by Mann-Whitney-U Test). CONCLUSION We conclude that triplet pregnancies presenting with dyspnoea show a high prevalence of abnormal echocardiographic findings. Since dyspnoea is a common sign in triplet pregnancies and is associated with a high rate of cardiac involvement, echocardiography and evaluation of maternal NT-proBNP could be considered to improve early diagnosis and perinatal management.

Abstract
INTRODUCTION This study aimed to determine the incidences of feto-fetal transfusion syndrome (FFTS) and perinatal outcomes in triplet gestations with monochorionic placentation. MATERIALS AND METHODS In this retrospective cohort study, we evaluated the incidences of FFTS and perinatal outcomes at 28 days of age in cases of triplet gestations with monochorionic placentation who visited our centers before 16 weeks of gestation and delivered over a period of 11 years. RESULTS In 41 triplet gestations (17 monochorionic triamniotic, 22 dichorionic triamniotic, 1 dichorionic diamniotic, and 1 monochorionic monoamniotic), the incidence of FFTS was 17.1%, and the median gestational age at FFTS diagnosis was 19 weeks. In 123 triplets, the incidences of fetal death and neonatal death at 28 days of age were 8.1 and 0.9%, respectively. None of the surviving infants had grade 3 or 4 intraventricular hemorrhage, while cystic periventricular leukomalacia occurred in 6 of 113 infants (5.3%). The incidence of poor outcomes (death or any major neurological complication at 28 days of age) was 13.8%. DISCUSSION Seventeen percent of triplet pregnancies with monochorionic placentation developed FFTS, and 14% had a poor outcome. Therefore, triplet gestations with monochorionic placentation should be followed carefully.

Abstract
PURPOSE To investigate predictors of perinatal mortality in triplet pregnancies. METHODS Retrospective cohort managed in a tertiary teaching hospital (1998-2012) including all pregnancies with tree live fetuses at the first ultrasound examination, performed after 11 weeks of gestation. Primary end-point was defined as the number of children alive at hospital discharge. Ordinal stepwise regression analysis examined the association with maternal age, parity, pregnancy chorionicity, gestational age at our first ultrasound evaluation, presence of maternal clinical, obstetrical and fetal complications and gestational age at delivery. RESULTS Sixty-seven triplet pregnancies were first seen at 18.5 ± 6.8 weeks, 33 (49.3 %) were trichorionic, obstetric complications occurred in 34 (50.7 %) and fetal complications were diagnosed in 17 (25.4 %). Perinatal mortality rate was 249 ‰ (95 % CI 189-317) and 138 (73 %) children were discharged alive from hospital (11 pregnancies with no survivors; single and double survival in ten cases each; all children alive in 36). Regression analysis showed that presence of fetal complications (OR 0.10, 95 % CI 0.03-0.36) and gestational age at delivery (OR 1.55, 95 % CI 1.31-1.85) are significant predictors of outcome (p < 0.001). CONCLUSIONS Perinatal mortality in non-selected triplet pregnancies is high and is related to the presence of fetal complications and gestational age at delivery.

Abstract
BACKGROUND Multiple pregnancies are associated with higher rates of perinatal mortality and morbidity than singleton pregnancies, mainly due to an increased risk of preterm birth. Because fetal outcome is best at a particular range of maternal weight gain, it has been suggested that women with multiple pregnancies should take special diets (particularly high-calorie diets) designed to boost weight gain. However, 'optimal weight gain' in the mother in retrospective studies may merely reflect good growth of her babies and delivery at or near term (both associated with a good outcome) and artificially boosting weight gain by nutritional input may confer no advantage. Indeed, a high-calorie diet may be unpleasant to consume, and could lead to long-term problems of being overweight. It is therefore important to establish if specialised diets are actually of benefit to women with multiple pregnancies and their babies. OBJECTIVES To assess the effects of specialised diets or nutritional advice for women with multiple pregnancies (two or more fetuses). SEARCH METHODS We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (15 June 2015). SELECTION CRITERIA Randomised controlled trials, 'quasi-random' studies, and cluster-randomised trials of women with multiple pregnancies (two or more fetuses) either nulliparous or multiparous and their babies. Cross-over trials and studies reported only as abstracts were not eligible for inclusion. DATA COLLECTION AND ANALYSIS We identified no trials for inclusion in this review. MAIN RESULTS A comprehensive search of the Cochrane Pregnancy and Childbirth Group's Trials Register found no potentially eligible trial reports. AUTHORS' CONCLUSIONS There is no robust evidence from randomised trials to indicate whether specialised diets or nutritional advice for women with multiple pregnancies do more good than harm. There is a clear need to undertake a randomised controlled trial.

Abstract
OBJECTIVE We sought to determine the interventions utilized by maternal-fetal medicine specialists in the prediction and prevention of preterm labor in higher-order multiple (HOM) gestations. STUDY DESIGN Online questionnaires and email surveys were sent to all the maternal-fetal medicine specialists in Canada (n=122). Questionnaire items included interventions physicians routinely recommended for HOM gestations including: (1) bed rest; (2) cervical length measurement on transvaginal ultrasound; (3) corticosteroids use; (4) cerclage; and (5) tocolytic therapy. RESULTS Response rate was 66% (81/122), with 68% of respondents in practice for >10 years. Of physicians, 91% did not routinely recommend bed rest (95% confidence interval [CI], 84.7-97.2). In all, 82% (95% CI, 73.63-90.4%) recommended routine cervical length assessment with 32.3% (95% CI, 20.7-43.2) and 37.1% (95% CI, 25.3-48.6) of this group suggesting assessment at 16-18 and 19-21 weeks, respectively. Frequency of assessment varied from biweekly (53.3%; 95% CI, 40.9-65.0), to monthly (23.3%; 95% CI, 12.8-33.1), to a single measurement repeated only if abnormal (12.5%; 95% CI, 4.5-20.8). In all, 28% (95% CI, 18.2-37.8) recommended routine administration of corticosteroids for lung maturation. Timing of administration varied, with 24% initiating steroids between 24-26 weeks, 59% between 27-28 weeks, and 17% after 28 weeks. None reported routine cerclage placement. However, 71% (95% CI, 61.1-80.8) would perform cerclage based on history or ultrasound. Of respondents, 81% (95% CI, 72.4-89.5) would consider using tocolytic agents for threatened preterm labor including calcium channel blockers (94%), nonsteroidal antiinflammatory drugs (5%), and nitroglycerin transdermal patch (24%). CONCLUSION The variable practice guidelines and paucity of data for management of HOM pregnancy places the onus on individual practitioners to develop their own management schemes. This results in heterogeneous management, which is based on conflicting international guidelines, studies, expert opinion, or past experience.

Abstract
OBJECTIVE The objective of the study was to assess in trichorionic triplet pregnancies the effectiveness of elective reduction to twins. STUDY DESIGN This was a nationwide retrospective cohort study. We compared the time to delivery and perinatal mortality in trichorionic triplet pregnancies electively reduced to twins with ongoing trichorionic triplets and primary dichorionic twins. RESULTS We identified 86 women with reduced trichorionic triplet pregnancies, 44 with ongoing trichorionic triplets, and 824 with primary twins. Reduced triplets had a median gestational age at delivery of 36.1 weeks (interquartile range [IQR], 33.3-37.5 weeks) vs 33.3 (IQR, 28.1-35.2) weeks for ongoing triplets and 37.1 (IQR, 35.3-38.1) weeks for primary twins (P < .001). The total number of surviving children in the reduced group was 155 (90%) vs 114 (86%) in the ongoing triplet group. After reduction, 75 of women (87%) had all their fetuses surviving, compared with 36 (82%) (relative risk [RR], 1.3; 95% confidence interval [CI], 0.72-2.3) for ongoing triplets and 770 (93%) (RR, 0.91; 95% CI, 0.82-1) for primary twins. There were 6 women without any surviving children (7%) after reduction vs 5 (11.4%) (RR, 0.81; 95% CI, 0.47-1.4) among women with ongoing triplets and 32 (3.9%) (RR, 1.7; 95% CI, 0.8-3.7) in women with primary twins. CONCLUSION In women with a triplet pregnancy, fetal reduction increases gestational age at birth with 3 weeks as compared with ongoing triplets. However, there the impact on neonatal survival is limited.

Abstract
OBJECTIVE The purpose of this study was to evaluate the perinatal risk of death by chorionicity at >22 weeks of gestation of triplet pregnancies. STUDY DESIGN In a retrospective cohort study, the perinatal data were collected from triplet pregnancies in Japanese perinatal care centers between 1999 and 2009. We included maternal characteristics and examined the following factors: prenatal interventions, pregnancy outcome, and neonatal outcome. The association between fetal or neonatal death of triplets and chorionicity was evaluated by logistic regression analysis. RESULTS After the exclusion of 253 cases, the study group comprised 701 cases: 507 trichorionic triamniotic (TT) triplet pregnancies, 144 diamniotic triamniotic (DT) triplet pregnancies, and 50 monochorionic triamniotic (MT) triplet pregnancies. The mortality rate (fetal death at >22 weeks of gestation; neonatal death) in triplets was 2.6% and included 2.1% of TT triplet pregnancies, 3.2% of DT triplet pregnancies, and 5.3% of MT triplet pregnancies. No significant risk of death was identified in DT triplet pregnancies; however, MT triplet pregnancies had a 2.6-fold greater risk (adjusted odds ratio, 2.60; 95% confidence interval, 1.17-5.76; P = .019) compared with TT triplet pregnancies. Prophylactic cervical cerclage did not reduce the perinatal mortality rate at >22 weeks of gestation in triplets. CONCLUSION The risk of death for MT triplet pregnancies is significantly higher than that of TT triplet pregnancies; however, the risk of death for DT triplet pregnancies is not.

Abstract
OBJECTIVE To review clinical features and short-term outcomes of triplet pregnancies among Japanese women. METHODS A retrospective analysis was carried out among 320 Japanese women with triplet pregnancies (8 monochorionic, 75 dichorionic, and 150 trichorionic triplets; 87 with unknown placental chorionicity) who delivered at 22 gestational weeks or more between January 2005 and December 2008. RESULTS Delivery was by cesarean for 315 (98%) women. Gestational age at delivery was 32.3±2.8 weeks (mean±SD) and 33.2 weeks (median), and 97%, 61%, and 14% of women delivered at less than 37, less than 34, and less than 30 gestational weeks, respectively. For live-born infants, mean birth weight was 1762±437 g, 1608±396 g, and 1406±380 g for the heaviest, middle, and lightest triplet, respectively. Eighteen (5.6%) women experienced perinatal mortality (3 triplets for 1 woman, 2 triplets for 4 women, and 1 triplet for 13 women). Perinatal mortality was 25 deaths per 1000 deliveries, and decreased with increasing number of chorionic membranes (125, 44, and 20 per 1000 mono-, di-, and trichorionic triplet deliveries, respectively). CONCLUSION Short-term outcomes were good among triplet pregnancies in Japan. The data may be useful for counseling Japanese women with triplet pregnancies.

Abstract
OBJECTIVE To review outcomes following reductions in trichorionic triplet pregnancies at our institution. METHOD Retrospective analysis of the outcome of trichorionic triamniotic triplets reduced to singletons (group I, n = 44) or twins (group II, n = 136) at 10 and 12 weeks of gestation. RESULTS Reduction to one or two was based on parent's preference, hence unrelated to any specific obstetrical or maternal issue. Early fetal loss rate (e.g. <24 weeks) was 9.1% in group I versus 5.1% in group II (p = 0.83). In group I, the take-home baby rate was 86.4% versus 91.9% in group II (p = 0.8). In group I, 17.5% of the women gave birth between 33 and 36(+6) weeks of gestation versus 40.6% in group II (p = 0.026). Delivery beyond 37 weeks was 72.5% in group I and 46.9% in group II (p = 0.01). Intrauterine growth restriction rate was 27.0% in group I versus 45.0% in group II (p = 0.049). CONCLUSION Reduction to one rather than two fetuses led to significantly higher term delivery rate without significant differences in fetal loss rate or take-home baby rate.

Abstract
As the incidence of twin gestation increases, it is important to consider the maternal risks associated with carrying multiples. Compared with singleton gestation, there are increased risks to the mother during the antepartum, intrapartum, and postpartum periods. Certain pregnancy complications are more likely to occur during a twin gestation, including preeclampsia and other hypertensive disorders, antepartum hospitalization for preterm labor or abnormal bleeding, nutritional deficiencies, cesarean delivery, and postpartum hemorrhage. Women carrying twins may benefit from early education regarding these issues, close maternal monitoring as well as physical therapy sessions, and nutrition counseling during their pregnancies.

Abstract
OBJECTIVE To determine whether the use of vaginal progesterone in asymptomatic women with a sonographic short cervix (≤ 25 mm) in the midtrimester reduces the risk of preterm birth and improves neonatal morbidity and mortality. STUDY DESIGN Individual patient data metaanalysis of randomized controlled trials. RESULTS Five trials of high quality were included with a total of 775 women and 827 infants. Treatment with vaginal progesterone was associated with a significant reduction in the rate of preterm birth <33 weeks (relative risk [RR], 0.58; 95% confidence interval [CI], 0.42-0.80), <35 weeks (RR, 0.69; 95% CI, 0.55-0.88), and <28 weeks (RR, 0.50; 95% CI, 0.30-0.81); respiratory distress syndrome (RR, 0.48; 95% CI, 0.30-0.76); composite neonatal morbidity and mortality (RR, 0.57; 95% CI, 0.40-0.81); birthweight <1500 g (RR, 0.55; 95% CI, 0.38-0.80); admission to neonatal intensive care unit (RR, 0.75; 95% CI, 0.59-0.94); and requirement for mechanical ventilation (RR, 0.66; 95% CI, 0.44-0.98). There were no significant differences between the vaginal progesterone and placebo groups in the rate of adverse maternal events or congenital anomalies. CONCLUSION Vaginal progesterone administration to asymptomatic women with a sonographic short cervix reduces the risk of preterm birth and neonatal morbidity and mortality.

Preterm deliveries that result from multiple pregnancies associated with assisted reproductive technologies in the USA: a cost analysis. Curr Opin Obstet Gynecol 2011; 23:168-73.

Abstract
PURPOSE OF REVIEW Simultaneous transfer of multiple embryos in an assisted reproductive technology (ART) cycle results in a high rate of multiple pregnancy. Besides the medical complications associated with multiple pregnancy, the financial burden of the resultant preterm infants is also substantial. The current review evaluates the costs associated with the care of preterm infants that are born as a result of ART-associated multiple pregnancies. RECENT FINDINGS In 2006, 30% of all ART live births were multiple infant deliveries in the USA. This resulted in 48% of all ART neonates being the product of a multiple infant delivery. In the same year, 62% of ART twins and 97% of ART triplets were delivered preterm, corresponding to approximately 17 000 infants. The Board of Health Sciences Policy has estimated the mean cost of each preterm infant to be US$ 51 600. Therefore, the financial burden of ART-associated preterm deliveries is estimated to be approximately US$ 1 billion annually. This figure has remained essentially unchanged between 2001 and 2006, despite decreasing number of embryos transferred, due to increasing total number of ART cycles performed. SUMMARY Preterm deliveries that result from ART-associated multiple pregnancies add a substantial burden to overall US healthcare expenditure annually. Policies limiting the number of embryos transferred should be considered with a perspective to increase elective single embryo transfers.

Abstract
OBJECTIVE To examine temporal trends of cardiomyopathy in pregnancy and its association with feto-infant morbidity outcomes. DESIGN AND METHODS We performed a population-based retrospective cohort analysis utilizing the Florida hospital discharge data linked to vital statistics for 1998 to 2007 (N = 1 738 860). Prevalence rates and trend statistics of cardiomyopathy were computed. Conditional logistic regression models were used to generate adjusted odds ratios (AOR) and 95% confidence intervals (CI). RESULTS The annual prevalence of cardiomyopathy in pregnancy increased from 8.5/100 000 births to 32.7/100 000 (p for trend <0.0001), representing an absolute increase of 24% and a relative increase of 300% over the decade. Infants born to women with cardiomyopathy were at higher risk for feto-infant morbidities, including low birth weight (AOR = 3.49, 95% CI: 2.97-4.11), very low birth weight (AOR = 4.43, 95% CI: 2.98-6.60), preterm birth (AOR = 3.33, 95% CI: 2.88-3.85), very preterm birth (AOR = 5.22, 95% CI: 3.92-6.97) and small for gestational age (AOR = 1.57, 95% CI: 1.26-1.96). CONCLUSION The observed increasing prevalence of cardiomyopathy during pregnancy over the decade is of concern, as it is related to elevated risk for feto-infant morbidities. There is a need to delineate risk factors for this condition and to formulate appropriate preconception counseling for women with elevated risk for this diagnosis.

Abstract
BACKGROUND Multiple pregnancies are associated with higher rates of perinatal mortality and morbidity than singleton pregnancies, mainly due to an increased risk of preterm birth. Because fetal outcome is best at a particular range of maternal weight gain, it has been suggested that women with multiple pregnancies should take special diets (particularly high-calorie diets) designed to boost weight gain. However, 'optimal weight gain' in the mother in retrospective studies may merely reflect good growth of her babies and delivery at or near term (both associated with good outcome) and artificially boosting weight gain by nutritional input may confer no advantage. Indeed, a high-calorie diet may be unpleasant to consume, and could lead to long-term problems of being overweight. It is therefore important to establish if specialised diets are actually of benefit to women with multiple pregnancies and their babies. OBJECTIVES To assess the effects of specialised diets or nutritional advice for women with multiple pregnancies (two or more fetuses). SEARCH STRATEGY We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (31 January 2011). SELECTION CRITERIA Randomised controlled trials, 'quasi-random' studies, and cluster-randomised trials of women with multiple pregnancies (two or more fetuses) either nulliparous or multiparous and their babies. Crossover trials and studies reported only as abstracts were not eligible for inclusion. DATA COLLECTION AND ANALYSIS We identified no trials for inclusion in this review. MAIN RESULTS A comprehensive search of the Cochrane Pregnancy and Childbirth Group's Trials Register found no potentially eligible trial reports. AUTHORS' CONCLUSIONS There is no robust evidence from randomised trials to indicate whether specialised diets or nutritional advice for women with multiple pregnancies do more good than harm. There is a clear need to undertake a randomised controlled trial.

Abstract
Following one year of secondary fertility, a couple conceived with a quadruplet after transfer of three embryos through IVF-ICSI. At 36 weeks and 2 days of gestation, the mother developed gestational induced hypertension and delivered the next day by caesarean section. Pathology confirmed the zygosity to be trichorionic quadramniotic and all four babies were discharged home with their mother on postoperative day 3. Herein, we describe a successfully managed high-risk pregnancy case. A review of the literature was conducted and to our knowledge no other cases with similar criteria ever reached such advanced gestational age.

Abstract
OBJECTIVE To determine the prevalence and the relative benefits conferred by selective and spontaneous reduction of one or more fetuses in trichorionic triamniotic triplet pregnancies on time to delivery. DESIGN Retrospective cohort study. SETTING Academic medical center. PATIENT(S) IVF patients with trichorionic triamniotic triplets between January 1998 and December 2007. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Gestational length at time of delivery. RESULT(S) Selective reduction to twins was used in 87 of the 153 (56.9%) triplet pregnancies that did not spontaneously reduce prior to <12 weeks, and was associated with longer gestation (13.9 days) with a fourfold greater likelihood of delivery at ≥ 34 weeks' gestation (odds ratio [OR], 4.3; 95% confidence interval [CI] = 2.2-8.6), compared with pregnancies not undergoing selective reduction. Compared with ongoing triplets, spontaneous reduction at <12 weeks' gestation (28 cases) was associated with longer gestation (13.7 days) and significantly greater likelihood delivering at or after 34 weeks' gestation (OR, 3.7; 95% CI, 1.4-9.9). CONCLUSION(S) Selective reduction of one fetus was used in 56.9% of patients in this population. Early spontaneous reduction (<12 weeks) and selective reduction to twins each conferred similar benefits by extending time to delivery and increasing the likelihood of delivery at or after 34 weeks' gestation.

Abstract
OBJECTIVE Current guidelines recommend a gestational weight gain of 35-45 pounds for a twin pregnancy, but actual levels of weight gain during pregnancy among US women delivering twins are currently unknown. STUDY DESIGN We assessed gestational weight gain among 6345 US women who delivered twins from 2001 to 2006, using data collected from 28 states and New York City participating in a population-based surveillance system (PRAMS). RESULTS Approximately one-third of mothers who delivered twins gained 45 pounds or more during pregnancy. Weight gains were higher among women with lower prepregnancy body mass indexes. The percentage of twins with a normal birthweight increased with increasing gestational weight gains, except among obese women with the highest level of gain (>/= 65 pounds). CONCLUSION A notable percentage of US women who deliver twins gain above the current guidelines. The benefits of high gestational weight gain during twin pregnancies need to be balanced against an increased risk of maternal weight retention and later obesity.

Abstract
OBJECTIVE To review factors associated with high-order multiple births (HOMB) due to ovulation induction (OI) and the efficacy of strategies to reduce their occurrence. DESIGN Retrospective analysis of published studies of OI with intrauterine insemination (IUI) where patient and cycle characteristics were fully documented. RESULT(S) High-order multiple pregnancies (HOMP) were positively related to use of high doses of gonadotropin, number of 7-10 mm preovulatory follicles, and E(2), and inversely related to age and number of treatment cycles. Strategies successful in reducing HOMP include: use of clomiphene (CC) before gonadotropins, minimal gonadotropin doses, cancellation for more than three follicles >10-15 mm, and aspiration of excess follicles. Depending on the strategy used, 5%-20% of cycles may be canceled but HOMP rates can be less than 2% and pregnancy rates can average 10%-20% per cycle. Pregnancy rates per patient need not be reduced if low doses are continued for 4-6 cycles. CONCLUSION(S) High-order multiple pregnancies due to OI can be reduced to 2% or less by less aggressive stimulation without reducing overall chances of pregnancy for most patients.

Abstract
Background Multi-foetal pregnancies and multiple births including twins and higher order multiples births such as triplets and quadruplets are high-risk pregnancy and birth. These high-risk groups contribute to the higher rate of childhood mortality especially during early period of life. Methods We examined the relationship between multiple births and infant mortality using univariable and multivariable survival regression procedure with Weibull hazard function, controlling for child's sex, birth order, prenatal care, delivery assistance; mother's age at child birth, nutritional status, education level; household living conditions and several other risk factors. Results Children born multiple births were more than twice as likely to die during infancy as infants born singleton (hazard ratio = 2.19; 95% confidence interval: 1.50, 3.19) holding other factors constant. Maternal education and household asset index were associated with lower risk of infant mortality. Conclusion Multiple births are strongly negatively associated with infant survival in Nigeria independent of other risk factors. Mother's education played a protective role against infant death. This evidence suggests that improving maternal education may be key to improving child survival in Nigeria. A well-educated mother has a better chance of satisfying important factors that can improve infant survival: the quality of infant feeding, general care, household sanitation, and adequate use of preventive and curative health services.
