Association of blood cadmium levels in pregnant women with infant birth size and small for gestational age infants: The Japan Environment and Children's study. ENVIRONMENTAL RESEARCH 2020; 191:110007. [PMID: 32768474 DOI: 10.1016/j.envres.2020.110007] [Citation(s) in RCA: 14] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/13/2020] [Revised: 07/16/2020] [Accepted: 07/24/2020] [Indexed: 06/11/2023]
Abstract
BACKGROUND There is growing evidence of an association between cadmium (Cd) and unfavorable birth outcomes. The effect of Cd exposure on anthropometric measures at birth or small for gestational age (SGA) infants in a large, nationwide Japanese cohort remains to be clarified. OBJECTIVES To analyze the association between maternal blood Cd levels at different sampling times and sex-dependent infant birth size, weight, body length, chest, and head circumferences, in addition to SGA. METHODS Data of 17,584 pregnant women in the Japan Environment and Children's Study were analyzed for anthropometric measurements. For SGA determination, 13,969 cases of vaginal delivery were analyzed after excluding infants born by cesarean section. Maternal blood Cd levels were categorized into quartiles (Q1-Q4), and the Q1 was used as a reference. Multiple linear regression analysis was performed for anthropometric measurements, and multiple logistic regression analysis was used to investigate the association of maternal blood Cd levels with the risk of SGA. RESULTS Birth weight tended to decrease according to the increase in quartiles of blood Cd levels (15.63 g decrease [95% confidence level (CI): -33.26, 2.01] for Q4). The overall analysis revealed no decreases in body length and head and chest circumference, but subgroup analysis revealed that chest circumference tended to decrease according to the increase in quartiles in the female sex/third-trimester stratification (0.16 cm decrease [95% CI: -0.32, 0.00] for Q4). SGA risk was also higher and paralleled the increase in blood Cd levels associated with the female sex/third-trimester group (Odds Ratio 1.90 [95% CI: 1.23, 2.94] for Q4). CONCLUSION Our results provide further evidence of sex-specific health risks associated with Cd exposure in early life in a large Japanese pregnancy cohort.

Abstract
The effects of SARS-COV-2 infection on the pregnant women and their fetus growth have attracted worldwide concern. Our case study aimed to investigate the neonatal clinical outcomes of the recovered pregnant women from COVID-19 in China, expecting to provide the clinical references of urgent need for other countries. Our study recruited a total of 12 recovered pregnant women from COVID-19 prior to pregnancy termination. The maternal and neonatal clinical characteristics were recorded. Of them, the placental pathological characteristics of five participants were evaluated following the standard guidelines. Two of them chose induced labour due to being worry about the potential adverse effects of medical treatment for COVID-19 by themselves. For the others, 8 gave birth by cesarean section with certain indications and 2 by vaginal delivery. Their neonates were all live birth with ≥ 37 gestational weeks and high Apgar scores of 9 ∼ 10. For the neonate related biological samples, they all have negative results of RNA test, including nasopharyngeal swab, umbilical cord blood, amniotic fluid, vaginal fluid, placenta, or umbilical cord. Most of other pathological indicators of placental examination suggested no abnormal syndromes. Overall, we did not find any abnormal pregnancy complications and neonatal outcomes among them. We concluded that excess adverse effect on the fetus development due to COVID-19 in the recovered pregnant women should be less influential, especially, induce abortion due to the anxiety of COVID-19 treatment should be not advisable.

Abstract
OBJECTIVE To evaluate the effects of the duration of cryostorage on clinical outcomes after embryo transfer of vitrified blastocysts stored in an open-device slush-nitrogen (SN2 ) system. METHODS A retrospective cohort study was carried out on 1632 autologous vitrified-warmed blastocyst transfer cycles between January 2013 and June 2014. Duration of cryostorage was divided into four groups: Group I: 0-6 months (n=937); Group II: 7-12 months (n=299); Group III: 13-24 months (n=165); and Group IV: ≥25 months (n=231). The effects of the duration of cryostorage on the survival rate (SR), clinical pregnancy rate (CPR), live birth rate (LBR), and neonatal outcomes of vitrified blastocysts stored in an open-device SN2 system were evaluated. RESULTS There were no significant differences between groups in SR, CPR, LBR, and neonatal outcomes after autologous vitrified-warmed blastocyst transfer. Multivariate logistic regression analysis showed no effect on LBR from duration of cryostorage. CONCLUSION Vitrification using SN2 and long-term cryostorage in an open-device system are safe and effective and do not significantly affect clinical outcomes after embryo transfer.

Abstract
Background Healthcare organisations differ in performance even if they are located in the same country or region. Suitable managerial practices and organisational processes can lead to better health outcomes. As a result, hospitals are constantly looking for managerial arrangements that can improve outcomes and keep costs down. This study aims to identify different managerial models in neonatal intensive care units (NICUs) and their impact on a large number of outcomes. Methods The research was conducted in Italy, within the SONAR project. SONAR’s aim was to identify the characteristics of NICUs, monitor outcomes and promote best practices. This study includes 51 of the 63 NICUs that took part in the SONAR project. Questionnaires on the activities and managerial features were administered to doctors and nurses working in NICUs. A total of 643 questionnaires were analysed from doctors and a total of 1601 from nurses. A cluster analysis was performed to identify managerial models of NICUs. Results Three managerial models emerged from cluster analysis: traditional, collaborative and individualistic. In the “traditional” model the doctor is above the nurse in the hierarchy, and the nurse therefore has exclusively operational autonomy. The “collaborative” model has as key elements professional specialisation and functional coordination. The “individualistic” model considers only individual professional skills and does not concern the organisational conditions necessary to generate organisational effectiveness. The results also showed that there is an association between managerial model and neonatal outcomes. The collaborative model shows best results in almost all outcomes considered, and the traditional model has the worst. The individualistic model is in the middle, although its values are very close to those of traditional model. Conclusions Health management needs to assess NICU strategically in order to develop models to improve outcomes. This study provides insights for management useful for designing managerial characteristics of NICUs in order to achieve better results. NICUs characterised by a collaborative model in fact show better neonatal outcomes.

Abstract
Objectives To determine relationship between immediate postpartum umbilical cord pH, fetal distress and neonatal outcome. Methods This descriptive cross-sectional study was conducted in the department of Gynaecology, Lady Reading Hospital Peshawar, Pakistan, from January 2019 to July 2019. This study included 27 full-term pregnant women who had abnormal CTG during the active or latent phase of labour. Data were analyzed by IBM SPSS Statistics for Windows, Version 23.0. Results Out of 27, most patients 13 (48.14%) were in the age group 20-25 years,11 (40.74%) to 26-30 years and 3 (11.11%) belonged to 31-35 years of age group. CTG abnormalities were severe bradycardia, late deccelerations and persistent variable deccelerations with loss of baseline variability. Of all delivered babies, 21 (77%) babies had birth weight<3.5 kg and 6 (22%) had >3.5 kg birth weight. 20 (74.07%) had acidosis (pH <7.2) at the time of birth, of which one had severe hypoxemia and acidosis with pH 6.85. APGAR score at 0 minutes showed a strong positive correlation (r=0.818, p= <0.001) with cord pH, while APGAR at five minutes was also strongly correlated (r= 773, p=<0.001). Of all babies 18(66.66%) with PH less than 7.2 were admitted in NICU while only 2 babies with PH more than 7.2 were admitted. (p value= 0.005). Conclusion Low umbilical cord pH values of babies born by cesarean section (for fetal distress) are strongly correlated with low APGAR score at birth and higher rates of NICU admission.

Abstract
INTRODUCTION We aimed to study the correlation between the extent of placental abruption (PA), as grossly estimated immediately after delivery, and pregnancy outcomes, in correlation with placental histopathology. MATERIALS AND METHODS Pregnancy and placental reports of all pregnancies complicated by PA (clinically diagnosed) between 11/2008-12/2018 were reviewed. We compared maternal background, pregnancy outcomes, and placental histopathology between cases of PA divided into three groups according to the extent of abruption: Group 1-<30 %, Group 2-30-49 %, and Group 3->50 % of placental surface. Placental lesions were classified according to the current "Amsterdam" criteria. The primary outcome was defined as a composite of severe neonatal morbidity and included ≥ 1 of the following complications: seizures, intraventricular hemorrhage, hypoxic-ischemic encephalopathy, periventricular leukomalacia, blood transfusion, necrotizing enterocolitis, intrauterine fetal demise, or neonatal death. RESULTS A total of 260 PA cases were included: 111 (42.7 %) in Group 1, 94 (36.2 %) in Group 2, and 55 (21.1 %) in Group 3. The rate of the primary outcome (7.2 % vs. 11.7 % vs. 27.3 %, p = 0.02) was associated with the degree of PA as well as maternal heavy smoking (p = 0.04), DIC (p = 0.03), umbilical artery Ph <7.1 (p = 0.02), 5-minute Apgar scores <7 (p = 0.03), NICU admissions, placental maternal vascular malperfusion lesions (p = 0.04), and neonatal weights <5th percentile (0.04). In multivariable analysis severe adverse neonatal outcome was independently associated with the percentage of PA (aOR = 1.4, 95 % CI = 1.3-3.9). CONCLUSION The extent of placental abruption, as estimated by the examiner, correlated with DIC and severe neonatal outcomes and may serve as an early alarming sign in deliveries complicated by PA.

Abstract
Group B Streptococcus (GBS) is a kind of opportunistic pathogenic bacteria and mainly strikes the lower digestive tract and genitourinary tract. It is a major risk factor for neonatal babies, seriously threatening their lives. In the present study, we aimed to detect the GBS colonization in late pregnant women, and to study the effect of GBS on maternal and infants’ prognosis. Pregnant women with a gestational age of 35–37 weeks were enrolled in the study. Real-time polymerase chain-reaction (RT-PCR) was used to detect the colonization of GBS in the vaginal and rectal secretions for late pregnant women according to the screening guidelines. Chi-square test was applied to analyze the relationship between GBS colonization and clinical characteristics. A follow-up of 6 weeks was performed on the puerpera and infants after delivery. The positive rate of GBS was 12.6% in late pregnant women. GBS carrier state was positively related to several pregnancy outcomes, including intrauterine infection, premature rupture of membranes, postpartum hemorrhage, fetal distress and puerperal infection, as well as to part neonatal outcomes, containing neonatal infection, neonatal pneumonia and neonatal sepsis (all P < 0.05). GBS infection in late pregnant women results in adverse effects on maternal and neonatal outcomes.

Abstract
BACKGROUND Congenital heart defect is the leading malformation in China. There may have been changes in congenital heart defect incidence because of birth policy shift in China over past years. This study aimed to investigate the epidemiology, prenatal diagnosis, and outcomes of congenital heart disease to improve medical and policy decisions. METHODS Data on cases of congenital heart disease identified during 2014-2018 were taken from the Zhejiang provincial birth defects surveillance system. Chi-square test, odds ratio (OR) and 95% confidence interval (CI) were used to explore epidemiology, prenatal diagnosis, and birth outcomes of congenital heart disease. RESULTS The average incidence of congenital heart disease was 16.0 per 1000 births, which increased by 62.2% during 2014-2018(χ2trend = 181.41, P < 0.001). However, the average critical congenital heart incidence was 1.6 per 1000 births, which remained stable over time. Women aged ≤20 years (OR2.1, 95% CI 1.9-2.3) or ≥ 35 years (OR 1.2, 95% CI 1.2-1.3) were at higher risk of having babies with congenital heart disease than women aged 21-34 years. Women who gave birth in urban areas (OR 1.2, 95% CI 1.2-1.3), had a son (OR 1.3, 95% CI 1.3-1.4), or had multiple births (OR 4.0, 95% CI 3.7-4.4) were also at higher risk than those giving birth in rural areas, to girls, or single births, respectively. The three major subtypes of congenital heart disease were atrial septal defect (67.9%), patent ductus arteriosus (34.7%), and ventricular septal defect (6.4%). The prenatal detection rate of critical congenital heart disease was 90.0%, which was far higher than total congenital heart disease, at 22.2% (χ2 = 1687.67, P < 0.001). There were 1457 (17.1%) stillbirths, 106 (1.2%) early neonatal deaths, and 6983 (81.7%) live births associated with congenital heart disease. CONCLUSIONS The high incidence of congenital heart disease in Zhejiang might be attributable to the large proportion of mild congenital heart disease. The incidence of critical congenital heart disease, the prenatal detection rate, and perinatal deaths from congenital heart disease are comparable to those in other studies.

Abstract
INTRODUCTION The Management of Myelomeningocele Study was a multicenter randomized trial to compare prenatal and standard postnatal repair of myelomeningocele (MMC). Neonatal outcome data for 158 of the 183 randomized women were published in The New England Journal of Medicine in 2011. OBJECTIVE Neonatal outcomes for the complete trial cohort (N = 183) are presented outlining the similarities with the original report and describing the impact of gestational age as a mediator. METHODS Gestational age, neonatal characteristics at delivery, and outcomes including common complications of prematurity were assessed. RESULTS Analysis of the complete cohort confirmed the initial findings that prenatal surgery was associated with an increased risk for earlier gestational age at birth. Delivery occurred before 30 weeks of gestation in 11% of neonates that had fetal MMC repair. Adverse pulmonary sequelae were rare in the prenatal surgery group despite an increased rate of oligohydramnios. There was no significant difference in other complications of prematurity including patent ductus arteriosus, sepsis, necrotizing enterocolitis, periventricular leukomalacia, and intraventricular hemorrhage. CONCLUSION The benefits of prenatal surgery outweigh the complications of prematurity.

Abstract
Placenta-associated pregnancy complications (fetal growth restriction and preeclampsia) are traditionally classified as "early" and "late" due to their different pathophysiology, histopathology, and pregnancy outcomes. As placental abruption (PA) represents another placenta-associated complication, we aimed to study if this categorization can be applied to PA as well. Pregnancy and placental reports of all pregnancies complicated by PA between November 2008 and January 2019 were reviewed. Maternal background, pregnancy outcomes, and placental histopathology were compared between cases of PA < 34 weeks (early PA group) vs. > 34 weeks (late PA group). Placental lesions were classified according to the "Amsterdam" criteria. The primary outcome was severe neonatal morbidity (≥ 1 severe neonatal complications: seizures, IVH, HIE, PVL, blood transfusion, NEC, or death). Included were 305 cases of PA, 71 (23.3%) in the early group and 234 (76.7%) in the late group. The early PA group was characterized by higher rates of vaginal bleeding upon presentation (p = 0.003), DIC (p = 0.018), and severe neonatal morbidity (p < 0.001). The late PA group was characterized by a higher rate of urgent Cesarean deliveries (p < 0.001). The early PA group was characterized by higher rates of placental maternal vascular malperfusion (MVM) lesions (p < 0.001), maternal inflammatory response (MIR) lesions (p < 0.001), placental hemorrhage (p < 0.001), and a lower feto-placental ratio (p < 0.001). Using regression analysis, we found that severe neonatal morbidity was independently associated with early abruption (aOR = 5.3, 95% CI = 3.9-7.6), placental MVM (aOR = 1.5, 95% CI = 1.2-1.9), placental MIR (aOR = 1.9, 95% CI = 1.4-2.3), and inversely associated with antenatal corticosteroids (aOR = 0.9, 95% CI = 0.6-0.98). "Early" and "late" PA significantly differ in their presentation, placental pathology, and pregnancy outcomes.

Abstract
OBJECTIVE To correlate uterine artery Doppler findings with maternal and neonatal outcomes in early- and late-onset preeclampsia with severe features. METHODOLOGY Doppler scan was done in both uterine arteries. Maternal and neonatal outcomes in women with abnormal and normal Doppler results were compared. RESULTS Abnormal Doppler results were present in 45 women (75%). Thirty-four (56.7%) women had abnormal RI, 19 (31.6%) had abnormal PI, and 36 (60%) had diastolic notch. Of the women who participated in the study, 21.6% developed maternal complications, and the majority belonged to the early-onset severe preeclampsia group. Diastolic notch was twofold more frequent in the early group. RI was abnormal in 63% of the early-onset and 50% of the late-onset group. CONCLUSION Pregnancies with early-onset preeclampsia who had abnormal uterine artery Doppler findings were at high risk for both maternal and neonatal complications, whereas those who had late-onset preeclampsia with abnormal Doppler findings only had an increased risk of perinatal complications.

Abstract
Background Early rescue intracytoplasmic sperm injection (ICSI) has been used in clinic as appropriate currently. While the outcomes of children born after this method were not well assessed. The purpose of this study was to evaluate the effect of early rescue ICSI on women with primary infertility. Methods Fresh embryo transfer cycles after rescue (n = 214) and conventional (n = 546) ICSI were retrospectively evaluated from women with primary infertility who underwent their first assisted reproductive technology cycles at our center in 2012–2017. The conventional ICSI group was subdivided into ICSI-1 (semen suitable for in vitro fertilization, IVF) and ICSI-2 (poor semen quality) to minimize bias from differences in semen quality. Pregnancy, delivery and neonatal outcomes were compared between groups. Results There was a higher rate of polyspermy and a lower rate of top-quality embryos (TQE) on day 3 for oocytes subject to rescue ICSI compared with conventional ICSI. This reduced the total number of TQE and the number of TQE transferred in the rescue ICSI group. There was no significant difference between groups in clinical pregnancy, ongoing pregnancy, early miscarriage and live birth. For pregnant women, gestational age, route of delivery, risk of preterm birth and gestational diabetes mellitus were also comparable. Neonatal outcomes including sex ratio, birth weight, neonatal intensive care unit admission and birth defects were also similar after rescue and conventional ICSI. Moreover, no differences were observed with the different ICSI subgroups. Conclusions For women with primary infertility who have a high risk of IVF fertilization failure (FF), rescue ICSI provides a safe and efficient alternative to minimize FF after initial IVF, but results in fewer TQE on day 3.

Abstract
PURPOSE To study if the transfer of morphological grade-CC blastocyst is effective and safe. METHODS This retrospective study included 2585 frozen-thawed embryo transfer (FET) cycles with grade-BB blastocysts and 102 FET cycles with grade-CC blastocysts during the period from January 2006 to December 2017. Pregnancy and neonatal outcomes of couples in two groups were analyzed before and after propensity score matching. RESULTS Pregnancy outcomes showed no significant difference in the rates of biochemical pregnancy, ectopic pregnancy, miscarriage, multiple gestation, gestational age (P > 0.05). However, the rates of intrauterine implantation, clinical pregnancy, and live birth were significantly lower in the grade-CC blastocyst transfer group than those in the grade-BB blastocyst transfer group (18.9% vs 46.0%, 21.6% vs 51.3%, 16.7% vs 41.4%, all P < 0.001, respectively) before and after propensity score matching. The assessment of neonatal outcomes showed no statistically significant differences in the birth weight, low birth weight, early-neonatal death, and birth defect, etc., similar results were also observed in the two matched cohorts. CONCLUSION Morphologically grade-CC blastocysts should be transferred rather than discarded, resulting in acceptable pregnancy and neonatal outcomes, which is beneficial to infertile patients suffering from repeated poor-quality embryos.

Significant deviations in sonographic fetal weight estimation: causes and implications. Arch Gynecol Obstet 2020; 302:1339-1344. [PMID: 32748053 DOI: 10.1007/s00404-020-05732-x] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2020] [Accepted: 07/28/2020] [Indexed: 10/23/2022]
Abstract
PURPOSE To allocate parameters associated with significant deviations in sonographic estimated fetal weight (EFW) and evaluate labor outcomes in such circumstances. METHODS Retrospective case-control study of women with a singleton gestation who underwent sonographic EFW within a week prior to delivery in a single tertiary university-affiliated medical center (2012-2018). The study group was comprised of 177 pregnancies in which sonographic EFW was at least ± 20% of actual birth weight, matched to 354 pregnancies with an accuracy of ± 1% of sonographic EFW to actual birth weight. Matching was based on age, gravidity, parity, and gestational age at delivery. Placental location, fetal presentation, spine position and amniotic fluid volumes during the ultrasound evaluation, as well as pregnancy outcomes, were compared between groups. RESULTS Median gestational age at delivery (37.0 vs. 38.0 weeks, p < 0.001), median estimated fetal weight (2591 vs. 3198 g, p < 0.001) and median birth weight (2916 vs. 3158 g, p = 0.001) were all lower in the non-accurate compared to the accurate weight estimation group. Ultrasound parameters significantly differed between groups. Women in the non-accurate, compared to accurate weight estimations group, presented higher rates of breech presentation (20.34 vs. 9.89%, p = 0.001), lower rates of anterior placenta (44.6 vs. 53.67%, p = 0.002) and lateral spine position (80.23 vs. 88.42%, p < 0.021). Multivariate analysis was utilized to control potential confounders, non-lateral spine position was found to be an independent risk factor for inaccuracies in EFW [OR = 2.505, 95% CI 1.159-5.416, p = 0.0196]. Obstetric parameters did not differ between groups. Higher rates of neonatal intensive care unit admission (20.34 vs. 11.02%, p = 0.003) and neonatal respiratory complications (7.34 vs. 3.39%, p = 0.042) were observed in the non-accurate EFW subgroup. Multivariate analysis demonstrated that inaccuracy in sonographic EFW was an independent risk factor for NICU admission (OR = 2.4, 95% CI 1.034-5.577, p = 0.041). CONCLUSION Accuracy in sonographic EFW depends on fetal presentation, spine position and placental location. Non-accuracy is associated with adverse neonatal outcomes.

Impact of implementation of a breech clinic in a tertiary hospital. BMC Pregnancy Childbirth 2020; 20:435. [PMID: 32727421 PMCID: PMC7391516 DOI: 10.1186/s12884-020-03122-4] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2020] [Accepted: 07/21/2020] [Indexed: 01/27/2023] Open
Abstract
BACKGROUND The incidence of breech presentation in single pregnancies at term is between three to 5 %. In order to support eligible women in their choice of mode of delivery, a dedicated breech clinic with a care pathway was developed in December 2015 in a tertiary referral centre in Brussels. The primary objective of this study was to evaluate the vaginal birth rate before and after the introduction of a dedicated breech clinic. The secondary objective was to compare the early neonatal outcomes before and after the breech clinic was introduced. METHODS This was a single centre retrospective and prospective study. The inclusion criteria were term (from 37 weeks), singleton fetus and breech presentation at delivery. The exclusion criteria were suspected intrauterine growth restriction, severe fetal malformations and intrauterine fetal demise. We used a composite outcome as an indicator of neonatal morbidity and mortality. RESULTS After the introduction of the breech clinic, we observed a significant increase in planned vaginal delivery from 7.4% (12/162) to 53.0% (61/115) (OR: 13.5; 95% CI: 6.7-27.0). The effective vaginal breech delivery rate (planned and unexpected) significantly increased from 4.3% (7/162) pre-implementation of breech clinic to 43.5% (50/115) post-implementation (OR: 17.0; 95% CI: 7.3-39.6). Neonatal outcomes were not statistically different between the before and after periods. CONCLUSION The introduction of a dedicated breech clinic has led to an increase in vaginal deliveries for breech babies without adversely affecting neonatal outcomes.

The live birth and neonatal outcomes in the subsequent pregnancy among patients with adverse pregnancy outcomes in first frozen embryo transfer cycles. Arch Gynecol Obstet 2020; 302:731-740. [PMID: 32468163 DOI: 10.1007/s00404-020-05608-0] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2019] [Accepted: 05/19/2020] [Indexed: 10/24/2022]
Abstract
PURPOSE To explore whether the adverse pregnancy outcomes in first frozen embryo transfer (FET) cycles affect live birth and neonatal outcomes in the subsequent pregnancy? METHODS This was a retrospective study. Women with a history of adverse pregnancy outcomes in first FET cycles started their subsequent embryo transfer cycles. The adverse pregnancy outcomes included biochemical pregnancy, ectopic pregnancy, and first-trimester pregnancy loss. The main outcomes of present study were live birth rate and neonatal outcomes. RESULTS Results showed patients with first-trimester pregnancy loss in first FET cycles had a 95 percent greater chance of live birth in subsequent FET cycles (OR 1.95, 95% CI 1.33-2.88). However, the biochemical pregnancy/ectopic pregnancy in initial FET cycles did not affect the chance of live birth in second cycles (biochemical pregnancy: OR 1.21, 95% CI 0.82-1.77; ectopic pregnancy: OR 1.06, 95% CI 0.55-2.05). The neonatal outcomes of singletons were not affected by the number of embryo transfer cycles. CONCLUSIONS Patients with first-trimester pregnancy loss in first FET cycle had a greater chance of live birth in second FET cycles, but the biochemical pregnancy/ectopic pregnancy in first FET cycles did not significantly affect the live birth in second FET cycles. The three types of adverse pregnancy outcomes in first FET cycles did not affect neonatal outcomes in the second cycles.

Abstract
Objective To study vaginal delivery outcomes and neonatal prognosis and summarize the management of vaginal delivery during the COVID‐19 pandemic. Methods A retrospective analysis of medical records and comparison of vaginal delivery outcomes between 10 pregnant women with clinical diagnosis of COVID‐19 and 53 pregnant women without COVID‐19 admitted to Zhongnan Hospital of Wuhan University between January 20 and March 2, 2020. Results of laboratory tests, imaging tests, and SARS‐CoV‐2 nucleic acid tests were also analyzed in neonates delivered by pregnant women with clinical diagnosis of COVID‐19. Results There were no significant differences in gestational age, postpartum hemorrhage, and perineal resection rates between the two groups. There were no significant differences in birth weight of neonates and neonatal asphyxia rates between the two groups. Neonates delivered by pregnant women with clinical diagnosis of COVID‐19 tested negative for SARS‐CoV‐2 infection. Conclusions Under the premise of full evaluation of vaginal delivery conditions and strict protection measures, pregnant women with ordinary type COVID‐19 can try vaginal delivery without exacerbation of COVID‐19 and without increasing the risk of SARS‐CoV‐2 infection in neonates. Pregnant women with ordinary type COVID‐19 could try vaginal delivery without increasing the risk of SARS‐CoV‐2 infection in their neonates.

Abstract
The risk of vertical transmission during vaginal delivery in COVID-19 pregnant patients is currently a topic of debate. Obstetric norms on vaginal birth assistance to reduce the potential risk of perinatal infection should be promoted by ensuring that the risk of contamination from maternal anus and faecal material is reduced during vaginal delivery.

Abstract
Background Few case reports and clinical series exist on pregnant women infected with SARS‐CoV‐2 who delivered. Objective To review the available information on mode of delivery, vertical/peripartum transmission, and neonatal outcome in pregnant women infected with SARS‐CoV‐2. Search strategy Combination of the following key words: COVID‐19, SARS‐CoV‐2, and pregnancy in Embase and PubMed databases. Selection criteria Papers reporting cases of women infected with SARS‐CoV‐2 who delivered. Data collection and analysis The following was extracted: author; country; number of women; study design; gestational age at delivery; selected clinical maternal data; mode of delivery; selected neonatal outcomes. Main results In the 13 studies included, vaginal delivery was reported in 6 cases (9.4%; 95% CI, 3.5–19.3). Indication for cesarean delivery was worsening of maternal conditions in 31 cases (48.4%; 95% CI, 35.8–61.3). Two newborns testing positive for SARS‐CoV‐2 by real‐time RT‐PCR assay were reported. In three neonates, SARS‐CoV‐2 IgG and IgM levels were elevated but the RT‐PCR test was negative. Conclusions The rate of vertical or peripartum transmission of SARS‐CoV‐2 is low, if any, for cesarean delivery; no data are available for vaginal delivery. Low frequency of spontaneous preterm birth and general favorable immediate neonatal outcome are reassuring. The rate of vertical or peripartum transmission of SARS‐CoV‐2 is low, if any, for cesarean delivery; no data are available for vaginal delivery.

Abstract
PURPOSE Epilepsy is a common neurological disorder that may complicate reproductive health. Our aim in this study was to provide prospective ascertainment of obstetric and neonatal outcomes in women with epilepsy and investigate whether the risk of pregnancy, delivery, and neonatal complications differed between women with epilepsy and women without epilepsy. METHODS Pregnant women with epilepsy and women without epilepsy (control group) were prospectively evaluated during the years 2013-2018. They were regularly followed by a neurologist and obstetrician until the end of pregnancy. RESULTS Delivery and perinatal outcomes were compared between 112 women diagnosed with epilepsy and 277 women without epilepsy. Epilepsy was a significant risk factor for preterm delivery, cesarean section, fetal hypoxia, and Apgar score ≤ 7 at 5 min in offspring (odds ratio (OR) = 2.83, 95% confidence interval (CI) 1.03-7.76; OR = 5.61, 95% CI 3.44-9.14; OR = 1.81, 95% CI 1.08-3.04; OR = 8.12, 95% CI 4.04-16.35, respectively). Seizures during pregnancy had influence on the preference of cesarean section as a mode of delivery (ОR = 3.39; 95% CI 1.40-8.17). The rate of perinatal hypoxia was significantly higher in children born by cesarean section (ОR = 2.84; 95% CI 1.04-7.76). There was no significant difference between women with epilepsy and controls in malformation rate. CONCLUSIONS Women with epilepsy had an increased risk of pregnancy and delivery complications. Cesarean section was associated with an increased risk of complications in offspring.

Abstract
INTRODUCTION Two possible causative pathways have been suggested to participate in the development of placental abruption (PA), an acute inflammatory pathway and placental vascular derived, a chronic pathway. We aimed to study the impact of the inflammatory pathway on maternal and neonatal outcome. METHODS The computerized medical files and placental reports of all pregnancies diagnosed with PA, between 11/2008-1/2019, at 24-42 weeks, were reviewed. Placental lesions were classified according to "Amsterdam" criteria into maternal and fetal vascular malperfusion lesions, acute inflammatory responses and chronic villitis. Composite neonatal morbidity included ≥1 of the following: seizures, intra-ventricular hemorrhage (IVH), hypoxic-ischemic encephalopathy, periventricular leukomalacia (PVL), blood transfusion, necrotizing enterocolitis (NEC), neonatal sepsis, respiratory distress syndrome, or neonatal death. Maternal and neonatal outcome were compared between PA with and without histologic chorioamnionitis (HC). RESULTS As compared to the PA without HC group (n = 267), the PA with HC group (n = 77) was characterized by lower gestational age (GA) at delivery (32.9 ± 5.5 vs. 35.6 ± 4.1 weeks, p < 0.001), higher rates of oligohydramnios (p < 0.001), bloody amniotic fluid at labor (p < 0.001), maternal postpartum fever (p < 0.001), longer maternal hospitalization (<0.001), and increased composite adverse neonatal morbidity (41.6% vs. 22.8%, p = 0.002). By multivariate analysis, GA and HC were found to be independently associated with adverse neonatal outcome, aOR 0.63 95% CI 0.43-0.78, p < 0.001, and aOR1.12, 95% CI 1.02-3.87, p = 0.04, respectively. DISCUSSION The involvement of the inflammatory causative pathway in the development of placental abruption, is associated with increased maternal and neonatal morbidity.

Eur J Obstet Gynecol Reprod Biol 2020; 246:165-168. [PMID: 32032929 DOI: 10.1016/j.ejogrb.2020.01.050] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/26/2019] [Revised: 01/24/2020] [Accepted: 01/31/2020] [Indexed: 10/25/2022]
Abstract
OBJECTIVE Reduced fetal movements (RFM) is an obstetric complaint known to be associated with adverse neonatal outcomes and should serve as an alarming sign in obstetric triage. Whether this assumption holds for twin pregnancies, is still an obstetric enigma, and this complaint is sometimes overlooked in twins. We, therefore, aimed to study neonatal outcomes in twin pregnancies complicated by RFM. We hypothesised that in twin pregnancy, maternal ability to perceive RFM will be limited, and therefore, will not be associated with adverse neonatal outcome. STUDY DESIGN Included were all dichorionic twin pregnancies between 2009-2019 who presented to our obstetric triage at a gestational age >34 weeks with an isolated complaint of RFM and delivered during the subsequent two weeks (RFM group). The control group included patients with twin pregnancies (matched for gestational age and maternal age) who presented for routine assessment and reported regular fetal movements throughout pregnancy (no RFM group). Data regarding pregnancy, delivery, and neonatal outcomes were compared between the groups. The primary outcome was a composite of adverse neonatal outcomes, which included one or more of the following: neonatal hypoglycemia, respiratory morbidity, cerebral morbidity, phototherapy, neonatal sepsis, blood transfusions, necrotizing enterocolitis, or neonatal death. Multivariable regression analysis was used to identify independent associations with adverse neonatal outcomes. RESULTS Maternal demographics and gestational age at delivery did not differ between the RFM group (n = 83 pregnancies and 166 neonates) and the no RFM group (n = 83 pregnancies and 166 neonates). Neonatal birthweights, as well as the rate of birthweights <10th centile, did not differ between the groups. There were 2 cases of fetal demise diagnosed at triage in the RFM group. The rate of the primary outcome, as well as NICU admissions, were significantly higher in the RFM group compared to the no RFM group (29.5 % vs. 19.2 %, p = 0.01 and 32.5 % vs. 19.2 %, p = 0.001). In multivariable analysis RFM (aOR = 1.18, 95 % CI = 1.06-2.73), and GA at delivery (aOR = 0.88, 95 % CI = 0.67-0.97) were associated with adverse neonatal outcome-independent from background confounders. CONCLUSION Patients presented to obstetric triage with twin pregnancies and isolated RFM had higher rates of adverse neonatal outcomes and NICU admissions compared to twin pregnancies without RFM.

The impact of chorionicity and the type of twin growth on the early neonatal outcome in twin pregnancies - 20 years of experience from one tertiary perinatal center. Taiwan J Obstet Gynecol 2020; 58:482-486.

Abstract
OBJECTIVE Twin pregnancies are associated with higher neonatal mortality and morbidity. Growth discordance and monochorionicity are among the factors that worsen the course of pregnancy. The study aimed to assess neonatal conditions and mortality in relation to growth type and chorionicity. MATERIALS AND METHODS Data from 820 pregnant women with twin pregnancies and their 1640 newborns were analyzed. The Apgar score and umbilical artery blood pH, as well as the rate of complications, were compared between dichorionic diamniotic (DCDA) and monochorionic diamniotic (MCDA) twins with symmetric and discordant growth. The Student's t-test and the Pearson chi-square test were used for comparisons. RESULTS There were 576 (70.2%) DCDA pregnancies, including 421 (73.1%) with symmetric growth and 155 (26.9%) with discordant growth, and 244 (29.8%) MCDA pregnancies, including 110 (45.1%) with symmetric growth and 134 (54.9%) with discordant growth. A significantly greater percentage of twins with discordant growth occurred in women older than 34 years than in those that were younger. An Apgar score of ≤7 was significantly more common among MCDA discordant twins, while an arterial umbilical blood pH of <7.2 was more common among MCDA twins with symmetric growth. Early neonatal deaths (n = 29; 1.8%), respiratory disorders, and a birth weight of <1500 g were significantly more common in MCDA twins than in DCDA twins. CONCLUSION MCDA twins with growth discordance are burdened with a higher risk of neonatal morbidity and mortality than symmetric DCDA twins. Chorionicity and growth discordancy are important determinants of the outcome of twin pregnancy.

Abstract
RESEARCH QUESTION Does preconception body mass index (BMI) affect neonatal outcomes in women with endometriosis who conceive with IVF? DESIGN This retrospective study included 7086 women who delivered a singleton live birth through IVF between December 2006 and December 2017. Of these, 1111 women were diagnosed with endometriosis by laparoscopy or laparotomy, while 5975 women received IVF treatment due to tubal factor or male factor infertility. Women were categorized according to predefined BMI groups (<18.5 kg/m2, BMI 18.5-24.9 kg/m2, ≥25 kg/m2). All comparisons performed were between women undergoing cryopreserved embryo transfer. RESULTS After stratification by BMI, underweight women with endometriosis showed higher preterm birth (PTB) rates compared with controls (14.61% versus 3.28%, P < 0.001), whereas normal weight and overweight/obese endometriotic women had similar PTB rates to controls. There was a significant interactive effect of endometriosis and maternal BMI on preterm delivery (P for interaction <0.05). After adjustment for potential confounding factors, the PTB rate remained consistently higher in the low BMI subgroup of women with endometriosis (adjusted odds ratio 4.66, 95% confidence interval 2.54-8.57), whereas this difference was not observed for the other BMI categories. Additionally, we noted no differences in the rate of early PTB, low birthweight, macrosomia, small for gestational age and large for gestational age between women with endometriosis and controls with respect to any preconception category of BMI. CONCLUSIONS Endometriotic patients who were underweight before conception (BMI <18.5 kg/m2) had a higher rate of PTB than women without endometriosis, but the difference was not observed in the other BMI categories.

Abstract
Pregnancy and neonatal outcomes in women diagnosed with endometriosis were investigated using data collected from the Korea National Health Insurance Claims Database and the National Health Screening Program for Infants and Children. A total of 3,778,561 women who gave birth between 2007 and 2015 were identified, and 1,938,424 primiparous women and their newborns were included in this study. Women with a diagnosis of endometriosis had a significantly higher incidence of multiple pregnancy, cesarean section, breech presentation, postpartum hemorrhage, placental abruption, placenta previa, and stillbirth than women without endometriosis (P < 0.0001). The rates of preterm birth and low birth weight were also increased in women with endometriosis (P < 0.0001). After adjusting for age, the estimated risks of these outcomes remained significant. Women previously diagnosed with endometriosis have an increased risk of adverse pregnancy and neonatal outcomes. Particular attention and information regarding these conditions should be provided to women with endometriosis during the preconception or antenatal periods.
