Abstract
Objective Cerebrovascular accidents (CVA) in childbearing-age women are rare. We aimed to evaluate the association between CVA events prior to delivery and obstetrical and neonatal outcomes. Methods A retrospective cohort study was conducted using data from the Healthcare Cost and Utilization Project, Nationwide Inpatient Sample (HCUP-NIS) database. All pregnant women who delivered or had a maternal death in the US from 2004 to 2014 were included in the study. We performed a comparison between women with an ICD-9 diagnosis of CVA before the delivery admission and those without. Obstetrical and neonatal outcomes were compared between the two groups. Results In total, 9,096,788 women fulfilled the inclusion criteria. Among them, 695 women (7.6 per 100,000) were diagnosed with a CVA before delivery. Women with a history of CVA, compared to those without, were more likely to be Black, older than 35 years of age, and suffer from obesity, chronic hypertension, pregestational diabetes, and thyroid disease. Patients with a prior CVA, compared to those without, had higher rates of pregnancy-induced hypertension (aOR 6.41, 95% CI 5.03-8.39, p < 0.001), preeclampsia (aOR 7.65, 95% CI 6.03-9.71, p < 0.001), and eclampsia (aOR 171.56, 95% CI 124.63-236.15, p < 0.001). Additionally, they had higher rates of preterm delivery (aOR 1.72, 95% CI 1.33-2.22,p = 0.003), cesarean section (aOR 2.69, 95% CI 2.15-3.37, p < 0.001), and maternal complications such as a peripartum hysterectomy (aOR 11.62, 95% CI 5.77-23.41, p < 0.001), postpartum hemorrhage (aOR 3.39, 95 % CI 2.52-4.54, p < 0.001), disseminated intravascular coagulation (aOR 16.32, 95% CI 11.33-23.52, p < 0.001), venous thromboembolism (aOR 45.08, 95% CI 27.17-74.8, p < 0.001), and maternal death (aOR 486.11, 95% CI 307.26-769.07, p < 0.001). Regarding neonatal outcomes, patients with a prior CVA, compared to those without, had a higher rate of intrauterine fetal demise and congenital anomalies. Conclusion Women with a CVA event before delivery have a significantly higher incidence of maternal complications, including hypertensive disorders of pregnancy, and neonatal complications, such as intrauterine fetal demise and congenital anomalies. Rates of maternal death were dramatically increased, and this association requires further evaluation.

Abstract
INTRODUCTION Intrauterine fetal death (IUFD) is defined as death of the fetus after the 20th week of gestation. Despite regular monitoring the incidence of IUFD remains high. This study aims to assess the incidence and maternal conditions associated with IUFD over term pregnancies in a twelve-year period. MATERIALS AND METHODS A retrospective descriptive study was conducted on a population of women in whom IUFD was diagnosed in a term pregnancy during the period from January 2010 to December 2022. The study was at the Clinic for Obstetrics and Gynecology, University Clinic Centre of Serbia. The analyses included the number of deliveries, live births, and stillbirths, as well as maternal, fetal, and placental conditions associated with the risk of IUDF. The statistical analysis involved descriptive statistical methods and one sample proportion. RESULTS The average age of the patients was 30 years. Most patients had secondary and higher education, and 70% of patients had regular pregnancy monitoring; 53.33% were primiparous and pregnancies occurred spontaneously. IUFD mainly occurred in the 39th week of gestation. In total, 38.3% had one to two associated diseases, 5% more than three, and 58.33% were healthy. Recurrence of IUFD was reported by 10% of patients, while 8.33% had a history of spontaneous abortion. Over 80% of placental histopathological findings indicated some pathology (e.g., infarction, infections, placental abruption). CONCLUSIONS The most significant risk factors for IUFD in term pregnancies in our population during the study period were hypertensive syndrome in pregnancy, obesity and gestational diabetes. Pathological findings on the placenta were more common in our study group than is usually reported with infractions of placental tissue being the most common, even in healthy women.

J Matern Fetal Neonatal Med 2023; 36:2241103. [PMID: 37518002 DOI: 10.1080/14767058.2023.2241103] [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: 08/02/2021] [Revised: 11/10/2022] [Accepted: 07/21/2023] [Indexed: 08/01/2023]
Abstract
PURPOSE Pruritus gravidarum is characterized by general pruritus in the absence of primary skin lesions. In this study, we sought to evaluate whether the offspring (≤ 18 years) of mothers diagnosed with pruritus gravidarum, are at increased risk of long-term dermatology-related hospitalization. METHODS A population-based, retrospective cohort study of all singleton deliveries between 1991 and 2021 was conducted at a tertiary medical center. Offspring of mothers diagnosed with pruritus gravidarum were compared to offspring of non-exposed mothers. First admission involving dermatological morbidity of the offspring were analyzed using ICD-9 codes. Kaplan-Meier survival curves were used to compare the cumulative hospitalization incidence between the groups and Cox regression models were utilized to adjust for confounding variables. RESULTS A total of 849 women out of 356,356 deliveries that fulfilled the inclusion criteria were diagnosed with pruritus gravidarum during pregnancy (0.23%). Among offspring to mothers with pruritus gravidarum versus non-pruritus gravidarum mothers, hospitalization rates involving dermatological morbidity, were higher (7.1% vs. 4.6%, p < .001) a finding that was consistent with the Kaplan-Meier survival curve (Log rank p = .002). In the Cox regression model, pruritus gravidarum was found to be a significant independent risk factor for dermatological-related hospitalizations in the offspring after controlling for gestational age, hypertensive disorders, diabetic disorders, meconium-stained amniotic fluid exposure and fertility treatments (adjusted HR = 1.44, 95% CI 1.12-1.85, p = .004). CONCLUSIONS Maternal pruritus gravidarum is an independent risk factor for long-term dermatology-related hospitalization in the offspring up to the age of 18 years.

[PMID: 37012128 PMCID: PMC10291742 DOI: 10.1016/j.ajog.2022.11.1283] [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: 08/31/2022] [Revised: 11/09/2022] [Accepted: 11/09/2022] [Indexed: 04/04/2023]
Abstract
Green-stained amniotic fluid, often referred to as meconium-stained amniotic fluid, is present in 5% to 20% of patients in labor and is considered an obstetric hazard. The condition has been attributed to the passage of fetal colonic content (meconium), intraamniotic bleeding with the presence of heme catabolic products, or both. The frequency of green-stained amniotic fluid increases as a function of gestational age, reaching approximately 27% in post-term gestation. Green-stained amniotic fluid during labor has been associated with fetal acidemia (umbilical artery pH <7.00), neonatal respiratory distress, and seizures as well as cerebral palsy. Hypoxia is widely considered a mechanism responsible for fetal defecation and meconium-stained amniotic fluid; however, most fetuses with meconium-stained amniotic fluid do not have fetal acidemia. Intraamniotic infection/inflammation has emerged as an important factor in meconium-stained amniotic fluid in term and preterm gestations, as patients with these conditions have a higher rate of clinical chorioamnionitis and neonatal sepsis. The precise mechanisms linking intraamniotic inflammation to green-stained amniotic fluid have not been determined, but the effects of oxidative stress in heme catabolism have been implicated. Two randomized clinical trials suggest that antibiotic administration decreases the rate of clinical chorioamnionitis in patients with meconium-stained amniotic fluid. A serious complication of meconium-stained amniotic fluid is meconium aspiration syndrome. This condition develops in 5% of cases presenting with meconium-stained amniotic fluid and is a severe complication typical of term newborns. Meconium aspiration syndrome is attributed to the mechanical and chemical effects of aspirated meconium coupled with local and systemic fetal inflammation. Routine naso/oropharyngeal suctioning and tracheal intubation in cases of meconium-stained amniotic fluid have not been shown to be beneficial and are no longer recommended in obstetrical practice. A systematic review of randomized controlled trials suggested that amnioinfusion may decrease the rate of meconium aspiration syndrome. Histologic examination of the fetal membranes for meconium has been invoked in medical legal litigation to time the occurrence of fetal injury. However, inferences have been largely based on the results of in vitro experiments, and extrapolation of such findings to the clinical setting warrants caution. Fetal defecation throughout gestation appears to be a physiologic phenomenon based on ultrasound as well as in observations in animals.

Abstract
Neonates born through meconium-stained amniotic fluid (MSAF) may develop complications including meconium aspiration syndrome, persistent pulmonary hypertension of newborn and death. The approach to the resuscitation of these neonates has significantly evolved for the past few decades. Initially, under direct visualization technique, neonates with MSAF were commonly suctioned below the vocal cords soon after delivery. Since 2015, Neonatal Resuscitation Program (NRP®) of the American Academy of Pediatrics has recommended against "routine" endotracheal suctioning of non-vigorous neonates with MSAF but favored immediate resuscitation with positive pressure ventilation via face-mask bagging. However, the China neonatal resuscitation 2021 guidelines continue to recommend routine endotracheal suctioning of non-vigorous neonates born with MSAF at birth. This review article discusses the differences and the rationales in the approach in the resuscitation of neonates with MSAF between Chinese and American NRP® guidelines over the past 60 years.

Abstract
PURPOSE Fertility at advanced age has become increasingly common, but the aging of parents may adversely affect the maturation of gametes and the development of embryos, and therefore the effects of aging are likely to be transmitted to the next generation. This article reviewed the studies in this field in recent years. METHODS We searched the relevant literature in recent years with the keywords of "advanced maternal/paternal age" combined with "adverse pregnancy outcome" or "birth defect" in the PubMed database and classified the effects of parental advanced age on pregnancy outcomes and birth defects. Related studies on the effect of advanced age on birth defects were classified as chromosomal abnormalities, neurological and psychiatric disorders, and other systemic diseases. The effect of assisted reproduction technology (ART) on fertility in advanced age was also discussed. RESULTS Differences in the definition of the range of advanced age and other confounding factors among studies were excluded, most studies believed that advanced parental age would affect pregnancy outcomes and birth defects in offspring. CONCLUSION To some extent, advanced parental age caused adverse pregnancy outcomes and birth defects. The occurrence of these results was related to the molecular genetic changes caused by aging, such as gene mutations, epigenetic variations, etc. Any etiology of adverse pregnancy outcomes and birth defects related to aging might be more than one. The detrimental effect of advanced age can be corrected to some extent by ART.

Abstract
UNLABELLED We aimed to evaluate the association between meconium-stained amniotic fluid during labor and offspring's childhood wheezing. This study analyzed the data of participants enrolled in the Japan Environment and Children's Study, a nationwide prospective birth cohort study, between 2011 and 2014. Data of women with singleton live births between 22 and 40 weeks' gestation were analyzed. Participants were categorized into two groups according to the presence or absence of meconium-stained amniotic fluid. The primary outcome measure was the offspring's childhood wheezing up to 3 years of age. A logistic regression model was used to calculate the adjusted odds ratio for childhood wheezing in children of women with meconium-stained amniotic fluid, considering those without meconium-stained amniotic fluid as a reference, taking into account the potential confounding factors affecting the incidence of wheezing. We analyzed data from 61,991 participants: 1796 (2.9%) participants had meconium-stained amniotic fluid during labor and 18,919 (30.5%) of the offspring had childhood wheezing. The adjusted odds ratios for the offspring's childhood wheezing were 0.89 (95% confidence interval, 0.79-0.99) in total participants, 0.87 (95% confidence interval, 0.78-0.97) in term births, and 2.00 (95% confidence interval, 0.98-4.09) in preterm births. CONCLUSIONS This study revealed a decreased incidence of childhood wheezing among the children of women with meconium-stained amniotic fluid in term births. By yet unknown mechanisms, meconium-stained amniotic fluid was associated with a decreased incidence of childhood wheezing in the offspring. Further studies are required to clarify the mechanism of one's own meconium in affecting their health condition. WHAT IS KNOWN • Meconium-stained amniotic fluid during labor is associated with several adverse perinatal outcomes, and meconium aspiration syndrome is associated with offspring's childhood asthma and wheezing. • Meconium-stained amniotic fluid during labor could be an independent protective factor for the offspring's dermatitis and skin rash. WHAT IS NEW • Whole cases with meconium-stained amniotic fluid during labor were associated with a decreased incidence of offspring's childhood wheezing up to 3 years of age. • This study may shed light on the effects of simple meconium-stained amniotic fluid on offspring's childhood health.

Lemieux P, Benham JL, Donovan LE, Moledina N, Pylypjuk C, Yamamoto JM. The association between gestational diabetes and stillbirth: a systematic review and meta-analysis. Diabetologia 2022; 65:37-54. [PMID: 34676425 DOI: 10.1007/s00125-021-05579-0] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/10/2021] [Accepted: 07/21/2021] [Indexed: 12/16/2022]
Abstract
AIMS/HYPOTHESIS Controversy exists over whether gestational diabetes increases the risk of stillbirth. The aim of this review was to examine the association between gestational diabetes and stillbirth. METHODS We performed searches of the published literature to May 2021. Study selection and data extraction were performed in duplicate by independent reviewers. Meta-analyses of summary measures were conducted using random-effect models for cohort and case-control studies separately. The study protocol was registered in PROSPERO (registration ID CRD42020166939). RESULTS From 9981 citations, 419 were identified for full-text review and 73 met inclusion criteria (n = 70,292,090). There was no significant association between gestational diabetes and stillbirth in cohort studies (pooled OR 1.04 [95% CI 0.90, 1.21]; I2 86.1%) or in case-control studies (pooled OR 1.57 [95% CI 0.83, 2.98]; I2 94.8%). Gestational diabetes was associated with lower odds of stillbirth among cohort studies presenting with an adjusted OR (pooled OR 0.78 [95% CI 0.68, 0.88]; I2 42.7%). Stratified analyses by stillbirth ≥28 weeks' gestation, studies published prior to 2013 and studies identified as low quality demonstrated a significantly higher odds of stillbirth in meta-regression (p = 0.016, 0.023 and 0.005, respectively). Egger's test for all included cohort studies (p = 0.018) suggests publication bias for the main meta-analysis. CONCLUSIONS/INTERPRETATION Given the substantial heterogeneity across studies, there are insufficient data to define the relationship between stillbirth and gestational diabetes adequately. In the main analyes, gestational diabetes was not associated with an increased risk of stillbirth. However, heterogeneity across studies means this finding should be interpreted cautiously.

Application of the international classification of diseases-perinatal mortality (ICD-PM) system to stillbirths: A single center experience in a middle income country. J Gynecol Obstet Hum Reprod 2021; 51:102285.

Abstract
OBJECTIVE The present study is intended to investigate the causes of stillbirth and its relationship with maternal conditions using the International Classification of Diseases-Perinatal Mortality (ICD-PM) system. MATERIAL AND METHODS All early and late fetal deaths between 2015 and 2020 were analyzed. Time of death, fetal causes, and the maternal conditions involved were identified using the ICD-PM classification system. RESULTS During the study period, out of 74,102 births a total of 475 stillbirths were recorded (6.4 per 1000 births), of which 83.6% of the cases were antepartum and 11.8% were intrapartum fetal deaths, and the time of death could not be determined in 4.6% of the cases. Fetal developmental disorder was the most common cause of antepartum fetal death (24.2%). Intrapartum deaths were mostly due to extremely low birth weight (44.6%). The most common maternal conditions involved were complications of placenta, cord, and membranes (19.8%). CONCLUSION The applicability of the ICD-PM classification system for stillbirths is easy. It was observed that fetal deaths mostly occurred in the antepartum period and the cause of death could not be identified in over half of these antepartum fetal deaths. In over half of the stillbirths, there is at least one maternal condition involved. The most common maternal conditions involved are complications of placenta, cord, and membranes. The most common maternal medical problem is hypertensive diseases of pregnancy.

Abstract
OBJECTIVE This study aimed to investigate the possible impact of meconium-stained amniotic fluid (MSAF) on the occurrence of neurological-related hospitalizations throughout childhood and adolescence. STUDY DESIGN In this population-based cohort analysis, all singleton deliveries occurring between 1991 and 2014 at the Soroka University Medical center were included and the long-term neurological-related hospitalizations were compared between children with and without MSAF during their delivery. A Kaplan-Meier survival analysis was constructed for the evaluation of cumulative hospitalization rate due to neurological morbidity over the 18 years of follow-up, and a Cox proportional hazards model was used to study the independent association between MSAF and childhood neurological morbidity while controlling for potential confounders. RESULTS During the study period, 243,725 deliveries met the inclusion criteria; 35,897 of the cohort (15%) constituted the exposed group (MSAF), while the rest of the cohort (n = 207,828) constituted the unexposed group (no MSAF). A total of 7,543 hospitalizations due to neurological-related morbidity were documented with a rate of 3.2% (1,152) in children exposed to MSAF as compared with 3.1% (6,391) in the unexposed group (OR 1.1, 95% confidence interval 0.9-1.1, p = 0.149). The survival curve showed a comparable cumulative hospitalization rate in the MSAF-exposed group compared with the unexposed group (log rank p = 0.349). The Cox analysis, controlled for gestational diabetes and hypertension, gestational and maternal ages, demonstrated MSAF exposure not to be an independent risk factor for neurological-related hospitalizations during childhood (adjusted hazard ratio = 1.03, 0.96-1.09). CONCLUSION Fetal exposure to MSAF, at any gestational age, does not appear to be an independent risk factor for later neurological-related hospitalizations throughout childhood and adolescence. KEY POINTS · MSAF is associated with several short-term complications such as low Apgar scores.. · The long-term implications of MSAF exposure are yet to be clearly defined.. · Fetal exposure to MSAF is not a risk factor for neurological morbidity throughout childhood..

Abstract
Whether meconium-stained amniotic fluid (MSAF) serves as an indicator of fetal distress is under debate; however, the presence of MSAF concerns both obstetricians and pediatricians because meconium aspiration is a major contributor to neonatal morbidity and mortality, even with appropriate treatment. The present study suggested that thick meconium in infants might be associated with poor outcomes compared with thin meconium based on chart reviews. In addition, cell survival assays following the incubation of various meconium concentrations with monolayers of human epithelial and embryonic lung fibroblast cell lines were consistent with the results obtained from chart reviews. Exposure to meconium resulted in the significant release of nitrite from A549 and HEL299 cells. Medicinal agents, including dexamethasone, L-Nω-nitro-arginine methylester (L-NAME), and NS-398 significantly reduced the meconium-induced release of nitrite. These results support the hypothesis that thick meconium is a risk factor for neonates who require resuscitation, and inflammation appears to serve as the primary mechanism for meconium-associated lung injury. A better understanding of the relationship between nitrite and inflammation could result in the development of promising treatments for meconium aspiration syndrome (MAS).

Abstract
OBJECTIVE Meconium stained amniotic fluid (MSAF) is a well-established risk factor for neonatal short-term respiratory complications. Little is known regarding the long-term morbidity. We investigated the possible association between MSAF and offspring respiratory morbidity. METHODS A population-based, cohort study of singleton deliveries occurring between 1991 and 2014 at a sole regional tertiary medical center was performed. Incidence of offspring respiratory related hospitalizations up to the age of 18 years were evaluated and compared to unexposed offspring. A Kaplan-Meier survival curve was used to compare cumulative respiratory morbidity incidence, and a Cox proportional hazards model was used to control for confounders. RESULTS During the study period 242,342 deliveries met the inclusion criteria. Of them, 14.7% (n = 35,609) were complicated with MSAF. Incidence of respiratory-related hospitalizations was significantly lower in children exposed to MSAF as compared to the unexposed group (4.5% vs. 4.9%, respectively; p < .01). Specifically, hospitalizations involving pneumonitis were significantly less common among the MSAF group (odds ratio, 0.35; 95% confidence interval [95% CI], 0.13-0.96; p = .03). The Kaplan-Meier survival curve demonstrated significantly lower total cumulative respiratory morbidity rates in the MSAF exposed group (log rank p < .01). In the Cox model, controlled for clinically relevant confounders, MSAF exhibited an independent and significant protective effect on long-term childhood respiratory morbidity (aHR, 0.91; 95% CI, 0.86-0.96; p < .01). CONCLUSIONS Fetal exposure to MSAF during labor appears to be associated with lower rates of long-term respiratory related hospitalizations in the offspring. Changes in offspring microbiome, as well as functional and anatomical modulations possibly resulting from MSAF exposure, might offer a plausible explanation of our findings.

Abstract
OBJECTIVE To identify risk factors in first pregnancy for perinatal mortality in the subsequent pregnancy. METHODS A retrospective population-based nested case-control study was conducted, including all women with two first singleton consecutive deliveries. Women with perinatal mortality in their first pregnancy were excluded, and cases with perinatal mortality in the second pregnancy were compared with controls who delivered a live birth. Characteristics and complications of the first pregnancy were compared between the groups using multivariable logistic models. RESULTS A total of 43 043 women were included in the study, 385 (0.9%) were cases. Cases, as compared with controls (live births), were younger (22.62 ± 4.0 vs 23.22 ± 4.0 years), with shorter inter-pregnancy interval (1.38 ± 1.55 vs 1.56 ± 1.53 years), and were more likely to have the following complications in their first pregnancy: severe pre-eclampsia (3.4% vs 1.7%), small for gestational age (12.5% vs 8.0%), preterm delivery (17.7% vs 7.8%), and congenital or chromosomal malformations (9.6% vs 5.9%). In multivariable analysis the risk for perinatal mortality was greater with each additional complication (adjused odds ratio [aOR] 1.64, 95% confidence interval [CI] 1.30-2.07, P < 0.001; aOR 2.55, 95% CI 1.61-4.04, P < 0.001; aOR 7.88, 95% CI 3.81-16.29, P < 0.001 for one, two, and three or more complications, compared with no complications, respectively). CONCLUSION Complications in first pregnancy ending with live birth are associated with increased risk for perinatal mortality in a subsequent pregnancy.

Abstract
BACKGROUND Intrauterine Fetal Death (IUFD) is a rare and tragic pregnancy complication. The main causes for IUFD are largely unknown. Particulate Matter (PM)2.5 exposure has been suggested as an IUFD risk factor. OBJECTIVES To study the association between maternal PM2.5 levels and IUFD risk, to address ethnicity as a possible effect modifier, and to identify a prenatal period during which PM2.5 is most harmful regarding IUFD risk. METHODS This is a retrospective cohort study, which included pregnant women at the Soroka University Medical Center between the years 2003-2017. Estimated PM2.5 levels were calculated per residence, using a hybrid model incorporating daily satellite remote sensing data at a 1 km spatial resolution. Multiple gestations, fetuses with congenital malformations or chromosomal abnormalities were excluded. Mean PM2.5 level was calculated per trimester, the entire pregnancy and the last gestational week. Analyses were also performed separately for the two ethnic groups in the study: Jews and Bedouin-Arabs. Multivariable analysis were applied to study the association between PM2.5 exposure at the different periods and IUFD risk. RESULTS The study included 87,887 pregnancies, 444 (0.5%) ended with IUFD. Mean PM2.5 levels ranged between 18.18 and 22.32 μm. First trimester and entire pregnancy PM2.5 levels were significantly associated with increased IUFD risk among Jewish women only. In a multivariable model, for every 10 μg/m3 unit increase in PM2.5 the risk for IUFD increases by 2.98 (95%CI 1.50-5.90) and by 3.61 (95%CI 1.32-9.85) during first trimester and the entire pregnancy, respectively, while adjusting for maternal age, smoking, socioeconomic score and season. CONCLUSIONS In this retrospective cohort an association was found between PM2.5 levels and IUFD among Jewish women only. These results strengthen the importance of addressing this effect modifier when studying air pollution effects on human health.

Abstract
BACKGROUND AND OBJECTIVES The existing prediction formulas for in-hospital mortality of very low birth weight (VLBW) infants were mostly developed in the 1990s or 2000s and thus may not reflect the recently improved levels of neonatal care. We conducted this study to build a model for predicting the in-hospital mortality using perinatal factors available soon after birth. METHODS We gathered data on VLBW infants from the Korean Neonatal Network, a nationwide, prospective, Web-based registry that enrolled patients from 2013 to 2017. Perinatal variables that were significantly associated with mortality in univariate logistic regression or those with apparent clinical importance were included in the multivariable logistic regression model. The final formula was constructed by considering the collinearity, parsimony, goodness of fit, and clinical interpretation. RESULTS A total of 9248 VLBW infants were analyzed, including 1105 (11.9%) who died during hospitalization. The mean gestational age was 29.0 ± 2.9 weeks and the mean birth weight was 1096 ± 280 g. Significant variables used in the final equation included polyhydramnios, oligohydramnios, gestational age, Apgar score at 1 minute, intubation at birth, birth weight, and base excess. In internal validation, the area under the curve (AUC) for the prediction of in-hospital mortality was 0.870 and the optimism-corrected AUC was 0.867. The prediction equation revealed good discrimination and calibration in the external validation as well (AUC: 0.876). CONCLUSIONS The newly developed Korean Neonatal Network prediction formula for in-hospital mortality could be a useful tool in counseling by providing a reliable prediction for the in-hospital mortality of VLBW infants.

Abstract
We aimed to study both the short- and long-term neurological implications in offspring born with confirmed knotting of the umbilical cord-"true knot of cord". In this population based cohort study, a comparison of perinatal outcome and long-term neurological hospitalizations was performed on the basis of presence or absence of true knot of cord. A Kaplan-Meier survival curve was constructed to compare the cumulative incidence of neurological hospitalizations between the study groups. Multivariable regression models were used to assess the independent association between true knot of cord, perinatal mortality and long term neurological related hospitalizations, while controlling for potential confounders. The study included 243,639 newborns, of them 1.1% (n = 2606) were diagnosed with true knot of the umbilical cord. Higher rates of intrauterine fetal demise (IUFD) were noted in the exposed group, a finding which remained significant in the multivariable generalized estimation equation, while controlling for confounders. The cumulative incidences of neurological hospitalizations over time were comparable between the groups. The Cox regression confirmed a lack of association between true knot of cord and total long term neurological related hospitalizations. While presence of true knot of the umbilical cord is associated with higher IUFD rates, in our population, however, its presence does not appear to impact the long term neurological health of exposed offspring.

Abstract
Amniotic fluid (AF) abnormalities are often associated with short-term adverse pregnancy outcomes, including cardiovascular-related. We sought to assess whether in utero exposure to AF abnormalities increases the risk for long-term cardiovascular morbidity of the offspring. We examined the incidence of cardiovascular disorders in singletons exposed and non-exposed to isolated oligohydramnios or polyhydramnios. Cardiovascular morbidity was assessed up to the age of 18 years according to a predefined set of ICD-9 codes. A Kaplan-Meier survival curves were used to compare cumulative morbidity incidence. A Cox proportional hazards model was constructed to control for confounders. During the study period, 195,943 newborns met the inclusion criteria, of which 2.0% (n = 4063) were in pregnancies diagnosed with isolated oligohydramnios and 2.9% (n = 5684) in pregnancies with isolated polyhydramnios. Children exposed to isolated AF disorders had significantly higher rates of long-term cardiovascular morbidity (p=.042). Children exposed to isolated oligohydramnios had higher cumulative incidence of cardiovascular morbidity (log-rank test p=.026) compared to unexposed children, opposing to what was demonstrate when comparing polyhydramnios vs. normal AFV (log-rank test p=.749). In the Cox regression model, while controlling for confounders, isolated oligohydramnios were found to be independently associated with long-term cardiovascular morbidity of the offspring.

Who Is at Risk for Preeclampsia? Risk Factors for Developing Initial Preeclampsia in a Subsequent Pregnancy. J Clin Med 2020; 9:jcm9041103. [PMID: 32294887 PMCID: PMC7230304 DOI: 10.3390/jcm9041103] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2020] [Revised: 04/09/2020] [Accepted: 04/10/2020] [Indexed: 12/16/2022] Open
Abstract
BACKGROUND The incidence of preeclampsia, which may cause significant maternal and perinatal morbidity, has risen in recent years, therefore it is critical to identify women at risk for preeclampsia. We aimed to identify risk factors in the first pregnancy (not complicated by preeclampsia) for preeclampsia in the subsequent pregnancy. METHODS A retrospective population-based nested case-control study was conducted, including all women with first (P1) and second (P2) singleton consecutive deliveries. Women who had experienced preeclampsia in their first pregnancy were excluded. Cases were defined as women with preeclampsia in their second pregnancy, and were compared to the controls, defined as women without this diagnosis in second pregnancy. Characteristics and complications of the first pregnancy were compared between cases and controls, and multivariable regression models were used to study the association between pregnancy complications (in the first pregnancy) and preeclampsia (in the subsequent pregnancy), while adjusting for confounders. RESULTS A total of 40,673 women were included in the study, 1.5% of second pregnancies were diagnosed with preeclampsia (n = 627, i.e., Cases). Cases, as compared to controls were older in their 1st pregnancy, with longer inter-pregnancy interval, and were more likely to have the following complications in their first pregnancy: preterm delivery (15.0% vs. 7.7%), low birthweight (17.9% vs. 10.3%), perinatal mortality (3.2% vs. 1.1%), and gestational diabetes (7.0% vs. 2.7%). In the multivariable model, adjusted for maternal age, obesity and inter-pregnancy interval, either one of these first pregnancy complications were independently associated with an increased risk for preeclampsia (adjusted OR for either of first pregnancy complication =1.73; 95% CI 1.37-2.14, <0.001), and the risk was greater for each additional complication (adjusted OR for ≥2 risk factors =3.54; 95% CI 2.28-5.52, p < 0.001). CONCLUSIONS Complications in first pregnancy, including preterm delivery, perinatal mortality and gestational diabetes, are risk factors for primary preeclampsia in second pregnancy. First pregnancy may serve as a window of opportunity to identify women at risk for future preeclampsia and other morbidities later in life.

Abstract
Umbilical cord accidents preceding labor are rare. Single and multiple nuchal cords, and true knot(s) of the umbilical cord, are often incidental findings noted at delivery of non-hypoxic non-acidotic newborns without any evidence of subsequent adverse neonatal outcome. In contrast to single nuchal cords, true knots of the umbilical cord, which occur in between 0.04% and 3% of all deliveries, have been associated with a reported 4 to 10 fold increased risk of stillbirth. First reported with real-time ultrasound, current widespread application of color Doppler, power Doppler and three-dimension sonography, has enabled increasingly more accurate prenatal sonographic diagnoses of true knot(s) of the umbilical cord. Reflecting the inability to visualize the entire umbilical cord at prenatal ultrasound assessment, despite detailed second and third-trimester scanning, many occurrences of incidental true knot of the umbilical cord remain undetected and are noted only at delivery. Although prenatal sonographic diagnostic accuracy is increasing, false positive sonographic diagnosis of true knot of the umbilical cord cannot be ruled out with certainty, and must continue to be considered clinically. Notwithstanding the inability to diagnose all true knots, currently there is a clear absence of clinical management guidelines by governing bodies regarding patients in whom prenatal sonographic diagnosis of true knot(s) of the umbilical cord is / are suspected. As a result, in many prenatal ultrasound units, suspected sonographic findings suggestive of or consistent with true knot of the umbilical cord are often disregarded, not documented, and patients are not uniformly informed of this potentially life-threatening condition, which carries an associated considerable risk of stillbirth. This commentary will address current perspectives of prenatal sonographic diagnostic and management challenges associated with true knot(s) of the umbilical cord in singleton pregnancies.

Accuracy of the Ultrasound Estimate of the Amniotic Fluid Volume (Amniotic Fluid Index and Single Deepest Pocket) to Identify Actual Low, Normal, and High Amniotic Fluid Volumes as Determined by Quantile Regression. JOURNAL OF ULTRASOUND IN MEDICINE : OFFICIAL JOURNAL OF THE AMERICAN INSTITUTE OF ULTRASOUND IN MEDICINE 2020; 39:373-378. [PMID: 31423632 DOI: 10.1002/jum.15116] [Citation(s) in RCA: 19] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/22/2019] [Revised: 07/29/2019] [Accepted: 07/30/2019] [Indexed: 06/10/2023]
Abstract
OBJECTIVES To identify abnormal amniotic fluid volumes (AFVs), normal volumes must be determined. Multiple statistical methods are used to define normal amniotic fluid curves; however, quantile regression (QR) is gaining favor. We reanalyzed ultrasound estimates in identifying oligohydramnios, normal fluid, and polyhydramnios using normal volumes calculated by QR. METHODS Data from 506 dye-determined or directly measured AFVs along with ultrasound estimates were analyzed. Each was classified as low, normal, or high for both the single deepest pocket (SDP) and amniotic fluid index (AFI). A weighted κ statistic was used to assess the level of agreement between the AFI and SDP compared to actual AFVs by QR. RESULTS The overall level of agreement for the AFI was fair (κ = 0.26), and that for the SDP was slight (κ = 0.19). Although not statistically significant (P = .792), the positive predictive value to classify a low volume using the AFI was lower compared to the SDP (35% vs 43%). The positive predictive value for a high volume was higher using the AFI compared to the SDP (55% versus 31%) but not statistically significant. The missed-call rate for high-volume identification by the SDP versus AFI was statistically significant (odds ratio, 5.5; 95% confidence interval, 2.04-14.97). The missed-call rate for low-volume identification by the AFI versus SDP was not statistically significant (odds ratio, 3.3; 95% confidence interval, 0.96-11.53). CONCLUSIONS Both the AFI and SDP identify actual normal AFVs by QR, with sensitivity higher than 90%. The SDP is superior for identification of oligohydramnios, and the AFI superior for identification of polyhydramnios.

Abstract
OBJECTIVE Meconium-stained amniotic fluid (MSAF) is a well-established risk factor for immediate adverse neonatal outcomes and was recently suggested to be associated with microbial invasion of the amniotic cavity. We aimed to determine whether MSAF exposure during labor carries a longer lasting impact on pediatric infectious morbidity. STUDY DESIGN A population-based cohort analysis was performed including all singleton deliveries occurring between 1991 and 2014 at a single tertiary medical center. Exposure was defined as the presence of MSAF during labor. Hospitalizations of the offspring up to the age of 18 years involving infectious diseases were evaluated. A Kaplan-Meier survival curve was used to compare cumulative morbidity and a Cox regression model to control for confounders. RESULTS During the study period, 243 725 deliveries met the inclusion criteria. Of them, 35 897 (14.7%) involved MSAF. Rate of infectious-related hospitalizations of the offspring was significantly lower in children exposed to MSAF as compared with the unexposed group (10.8% vs 11.1%, P < 0.05). Specifically, hospitalizations involving respiratory infections were significantly less common among the MSAF group (5.1% vs 5.6%, P < 0.001). The survival curve demonstrated significantly lower cumulative total infectious morbidity rates in the MSAF-exposed group (log rank P < 0.001). In the Cox model, controlled for maternal age, diabetes, hypertension, mode of delivery, and gestational age, exposed children exhibited lower rates of long-term childhood infectious morbidity (adjusted HR 0.96, 95% CI 0.92-0.99, P < 0.001). CONCLUSION Fetal exposure to MSAF during labor and delivery appears to be associated with lower rates of long-term infectious-related hospitalizations in the offspring.

Abstract
During pregnancy, iron requirements are increased to support maternal erythropoietic expansion and fetal growth and development. To meet these requirements, dietary iron absorption increases, and available iron stores are mobilized. These adjustments are thought to be in large part mediated by the iron-regulatory hormone hepcidin, which controls the concentrations of ferroportin, the sole exporter of iron into the extracellular fluid and blood plasma. Hepcidin regulation of iron availability during healthy and abnormal pregnancies is not well understood. In our cross-sectional study, we compared hepcidin, iron and hematological parameters between nonpregnant control women, healthy pregnant women in the first and second trimester, and women with spontaneous abortion in the first trimester. We found that in healthy pregnancy, hepcidin increased in the first trimester compared with nonpregnant women, but then decreased during the second trimester. The second trimester hepcidin levels decreased despite stable serum iron concentrations, suggesting active suppression of hepcidin, presumably to enhance iron availability as iron demand increases. In women with spontaneous abortion during the first trimester, hepcidin, serum iron, and ferritin concentrations were all increased compared with the first trimester healthy pregnancy. Although the specific mechanisms remain to be determined, our findings demonstrate that maternal hepcidin is regulated by signals related to the progression of pregnancy, and that pregnancy loss is associated with profound changes in maternal iron metabolism. These observations highlight the existence of fetoplacental signals that modulate maternal iron homeostasis.

Abstract
PURPOSE This study examined the prevalence of major depression and generalized anxiety disorder (GAD) in pregnant women with and without a diagnosis of oligohydramnios. DESIGN AND METHODS The study sample included 53 pregnant women with a diagnosis of oligohydramnios and 80 healthy pregnant women subjects. Major depression and GAD were diagnosed with the Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (SCID-I). FINDINGS Pregnant women with oligohydramnios had higher scores of depressive and anxiety symptom, and a higher prevalence rate of major depression (24.5% vs. 6.2%) and GAD (30.2% vs. 3.2%). PRACTICE IMPLICATIONS The results of the present study suggest that oligohydramnios appears to be associated with both major depression and GAD in pregnant women.

Abstract
Objective Risk factors for placental abruption have changed, but there has not been an updated systematic review investigating outcomes. Methods We searched PubMed, EMBASE, Web of Science, SCOPUS, and CINAHL for publications from January 1, 2005 through December 31, 2016. We reviewed English-language publications reporting estimated incidence and/or risk factors for maternal, labor, delivery, and perinatal outcomes associated with abruption. We excluded case studies, conference abstracts, and studies that lacked a referent/comparison group or did not clearly characterize placental abruption. Results A total of 123 studies were included. Abruption was associated with elevated risk of cesarean delivery, postpartum hemorrhage and transfusion, preterm birth, intrauterine growth restriction or low birth weight, perinatal mortality, and cerebral palsy. Additional maternal outcomes included relaparotomy, hysterectomy, sepsis, amniotic fluid embolism, venous thromboembolism, acute kidney injury, and maternal intensive care unit admission. Additional perinatal outcomes included acidosis, encephalopathy, severe respiratory disorders, necrotizing enterocolitis, acute kidney injury, need for resuscitation, chronic lung disease, infant death, and epilepsy. Conclusion Few studies examined outcomes beyond the initial birth period, but there is evidence that both mother and child are at risk of additional adverse outcomes. There was also considerable variation in, or absence of, the reporting of abruption definitions.

Abstract
OBJECTIVE To identify maternal characteristics independently associated with pregnancies resulting in intrauterine fetal demise (IUFD). STUDY DESIGN This was a population-based cohort study of all births taking place at the McGill University Health Centre in Montreal, Canada, between 2001 and 2007, using the McGill University Obstetrics and Neonatal Database. Maternal characteristics were compared between pregnancies that resulted in IUFD and control pregnancies resulting in live newborns. A logistic regression analysis was constructed to identify parameters independently associated with IUFD. RESULTS We identified 20,744 births during the study period, 87 of which were complicated by IUFD. Mothers with IUFD were more likely to be younger, with less formal education, higher rates of smoking during pregnancy, and more fetal anomalies (42.5% vs. 7.5%, P<0.001). After exclusion of pregnancies with congenital and/or chromosomal abnormalities, less formal education (7 vs. 13.6 school years, P<0.001) and smoking during pregnancy (24% vs. 7.7%, P<0.001) remained significantly more common in pregnancies resulting in IUFD. In the multivariable regression analysis both smoking and number of maternal school years were independently associated with IUFD pregnancies (OR 2.22 for smoking, P=0.007 and OR 0.865 for number of school years, P<0.001). CONCLUSION Lower levels of education and smoking during pregnancy are independent predictors of IUFD.

Abstract
OBJECTIVE To determine the association between maternal vitamin D levels and perinatal death. METHODS A retrospective cross-sectional study of all non-anomalous, singleton births (≥24 weeks) with perinatal death compared to a matched control group. Only pregnancies with a recorded vitamin D level at booking (8-19 weeks gestation) were included for analysis. Maternal vitamin D levels were categorized into normal, deficient and insufficient cohorts and variables compared between the three groups. RESULTS There were 31 perinatal deaths which were compared to 111 controls. Median vitamin D levels were lower in the perinatal death cohort compared to the control group (55 nmol/L versus 64 nmol/L, p = 0.43). There was no significant increase in deaths between the normal and deficient (p = 0.33) or insufficient (p = 0.09) groups. CONCLUSIONS Low maternal vitamin D levels at booking were not associated with an increased risk of perinatal demise.

Abstract
OBJECTIVE This guideline reviews the evidence relating to the diagnosis and obstetrical management of diabetes in pregnancy. OUTCOMES The outcomes evaluated were short- and long-term maternal outcomes, including preeclampsia, Caesarean section, future diabetes, and other cardiovascular complications, and fetal outcomes, including congenital anomalies, stillbirth, macrosomia, birth trauma, hypoglycemia, and long-term effects. EVIDENCE Published literature was retrieved through searches of PubMed and the Cochrane Library using appropriate controlled vocabulary (MeSH terms "diabetes" and "pregnancy"). Where appropriate, results were restricted to systematic reviews, randomized control trials/controlled clinical trials, and observational studies. There were no date limits, but results were limited to English or French language materials. VALUES The quality of evidence was rated using the criteria described in the Report of the Canadian Task Force on Preventive Health Care (Table 1). SUMMARY STATEMENTS Recommendations It is recognized that the use of different diagnostic thresholds for the "preferred" and "alternative" strategies could cause confusion in certain settings. Despite this, the committee has identified the importance of remaining aligned with the current Canadian Diabetes Association 2013 guidelines as being a priority. It is thus recommended that each care centre strategically align with 1 of the 2 strategies and implement protocols to ensure consistent and uniform reporting of test results.

Abstract
BACKGROUND Several studies and a recent meta-analysis have suggested that previous Cesarean section may increase the risk of stillbirth in a subsequent pregnancy. Given the high rates of Cesarean section in contemporary obstetric practice, this is of considerable public health importance. We sought to evaluate the potential that this association is the result of residual confounding bias. METHODS A large perinatal database (Alberta Perinatal Health Project) was searched to identify a matched set of first and second births from the years 1992-2006. Data on pregnancy outcomes, demographics and potential confounding factors were obtained. RESULTS The cohort was comprised of 98538 matched first and second births. Multivariate analysis did not reveal an association between previous Cesarean section and stillbirth, OR = 1.38 (0.98, 1.93). Restricting the analysis to a low risk group further attenuated the association, OR = .99 (0.62, 1.52). Analysis of the risk by indication for Cesarean section found that the risk was not increased for previous dystocia, OR = .91 (0.53, 1.55) nor for breech presentation, OR = 1.06 (0.50, 2.28) but only for other indications including non reassuring fetal status and fetal distress, OR = 1.96 (1.29, 2.98). CONCLUSIONS The results of our cohort analysis suggest that previous Cesarean section does not cause an increased risk of stillbirth.

Abstract
Intra-partum foetal death has been variously defined. However, a definition adopted at a technical consultation in 2006 is employed in this review. The quality of intra-partum care is a crucial factor for pregnancy outcome for both mothers and new-borns. Intra-partum stillbirth is defined as late foetal death during labour, which clinically presents as fresh stillbirth. The largest proportion of the world's stillbirths occurs in the late preterm, term and intra-partum periods. The Western Pacific region has the greatest reduction in stillbirth with a 3.8% annual decline between 1995 and 2009; however, the annual decline in the African region is less than 1%. Caesarean delivery is still uncommon, especially in rural areas: 1% of births in rural Sub-Saharan Africa and 5% in rural South Asia are by caesarean delivery; 62% of stillbirths occurred during the intra-partum period; 61.4% of stillbirths are attributable to obstetrical complications. Preventive measures aimed at reducing the incidence of intra-partum foetal death entail all measures aimed at improving quality antenatal care and preventing intra-partum asphyxia. This review discusses intra-partum foetal deaths from a Sub-Saharan African perspective. It explores the contribution of research within the region to identifying its impact on new-born health and potential cost-effective policy interventions.

Abstract
INTRODUCTION Stillbirth is an important issue in antenatal care and much remains unknown. This cohort study aims to explore the previously un-identified risk factor of third-trimester stillbirth to determine if Grade III preterm placental calcification (PPC) is associated with stillbirth. METHODS At a tertiary teaching hospital, obstetric ultrasonography was performed at 28 weeks' gestation to establish a diagnosis of PPC. Pregnancies with multifetal gestations, major fetal congenital anomalies, termination, cord accidents, apparent intrauterine infection, and antepartum complications were excluded. RESULTS 15,122 eligible pregnancies were categorized as stillbirth (n = 99) and livebirth (n = 15,023) groups. Between these two groups, there were no significant differences in maternal age, BMI, and parity, but significant differences in smoking and in PPC (35.4% vs 6.3%, p < 0.001) were observed. The peak occurrence of stillbirths was at 30 and 37 weeks' gestation, with a bimodal distribution of 11 and 17 stillbirths, respectively. For pregnancies with or without PPC, the incidences of stillbirths per-1000-births were 35.9 and 4.5, respectively. Using Kaplan-Meier survival analysis, at 40 weeks' gestation the cumulative stillbirth risk for pregnancies with PPC was higher compared to those without PPC. Logistic regression revealed that after adjusting for the effects of smoking and demographic factors, the risk of stillbirth (adjusted OR:7.62; 95% CI:5.00-11.62) was much higher when PPC was present. DISCUSSION Grade III PPC is associated with a higher incidence of stillbirth, and identified an independent risk factor. Being a pathologic implication, it may precede this negative outcome and can serve as a warning sign or marker when noted on ultrasonography.

Abstract
OBJECTIVE To determine whether caesarean delivery in the first pregnancy is a risk factor for unexplained antepartum stillbirth in a second pregnancy. DESIGN A population-based retrospective cohort study and meta-analysis. SETTING All maternity units in Scotland. PARTICIPANTS A cohort of 128 585 second births, 1999-2008. METHODS Time-to-event analysis and random-effects meta-analysis. MAIN OUTCOME MEASURE Risk of unexplained antepartum stillbirth in a second pregnancy. RESULTS There were 88 stillbirths among 23 688 women with a previous caesarean delivery (2.34 per 10 000 women per week) and 288 stillbirths in 104 897 women who had previously delivered vaginally (1.67 per 10 000 women per week, P = 0.002). When analysed by cause, women with a previous caesarean delivery had an increased risk of unexplained stillbirth (hazard ratio, HR 1.47; 95% confidence interval, 95% CI 1.12-1.94; P = 0.006) and, as previously observed, the excess risk was apparent from 34 weeks of gestation onwards. The risk did not differ in relation to the indication of the caesarean delivery, and was independent of maternal characteristics and previous obstetric complications. We identified three other comparable studies (two in North America and one in Europe), and meta-analysis of these studies showed a statistically significant association between previous caesarean delivery and the risk of antepartum stillbirth in the second pregnancy (pooled HR 1.40; 95% CI 1.10-1.77; P = 0.006). CONCLUSIONS Women who have had a previous caesarean delivery are at increased risk of unexplained stillbirth in the second pregnancy. TWEETABLE ABSTRACT Caesarean first delivery is associated with an increased risk of unexplained stillbirth in the next pregnancy.

Abstract
In this paper we describe health and morbidity characteristics of Bedouin women in southern Israel, based on papers published over the past 20 years. This is a unique population whose customs, tradition, singular circumstances as a population "in transit", and underprivileged socio-economic status are reflected in mental illness, pregnancy course, perinatal morbidity and mortality rates, and acute and chronic disease. Recognition of these characteristics can help the medical team treat various health problems in this population as well as other populations with similar characteristics.

Abstract
OBJECTIVE The purpose of this study was to investigate whether women who experienced at least 1 stillbirth are at increased risk for subsequent maternal long-term atherosclerotic morbidity. STUDY DESIGN We conducted a population-based study that compared the incidence of long-term atherosclerotic morbidity in a cohort of women with and without previous stillbirth. Deliveries occurred during a 25-year period. Patients with known cardiovascular or renal disease before the index pregnancy were excluded from the study. Kaplan-Meier survival curves were used to estimate the cumulative incidence of cardiovascular- and renal-related hospitalizations. Cox proportional hazards models were used to estimate the adjusted hazards ratio for cardiovascular- and renal-related hospitalizations. RESULTS Of 99,280 deliveries that met the inclusion criteria, 1879 deliveries (1.9%) occurred in patients who had had at least 1 stillbirth. After stillbirth, patients had a significantly higher cumulative incidence of cardiovascular and renal morbidity (Kaplan-Meier survival curve). During the follow-up period, patients with at least 1 stillbirth had higher rates of total cardiovascular and renal hospitalizations and had higher rates of simple and complex cardiovascular events. A significant stepwise increase was found between the number of stillbirths and future risk for cardiovascular morbidity. In a Cox proportional hazards model that was adjusted for confounders, previous stillbirth was associated independently with atherosclerotic morbidity. CONCLUSION Stillbirth is an independent risk factor for long-term maternal atherosclerotic morbidity. The risk is higher for patients with recurrent episodes of stillbirth.

Abstract
BACKGROUND Current understanding of the increased risk for stillbirth in gestational diabetes mellitus is often based on large cohort studies in which the risk of stillbirth in women with this disease is compared with the risk in women without. However, such studies could be susceptible to immortal time bias because, although many cohorts begin at 20 weeks' gestation, pregnancies must "survive" until 24-28 weeks in order to be screened and diagnosed with gestational diabetes. METHODS We describe the theoretical potential for immortal time bias in studies of stillbirth and gestational diabetes and then quantify the magnitude of the bias using 2006 United States vital statistics data. RESULTS Although gestational diabetes was protective against stillbirth when including all births (relative risk = 0.88 [95% confidence interval = 0.79-0.99]), restricting analyses to births at >28 weeks' gestation reversed the effect and diabetes became associated with an increased risk of stillbirth (1.25 [1.11-1.41]). CONCLUSION Immortal time before diagnosis of gestational diabetes may bias our understanding of the stillbirth risk associated with this condition.

Abstract
BACKGROUND Meconium-stained amniotic fluid (MSAF) represents the passage of fetal colonic content into the amniotic cavity. Meconium aspiration syndrome (MAS) is a complication that occurs in a subset of infants with MSAF. Secreted phospholipase A2 (sPLA2) is detected in meconium and is implicated in the development of MAS. The purpose of this study was to determine if sPLA2 concentrations are increased in the amniotic fluid of women in spontaneous labor at term with MSAF. MATERIALS AND METHODS This was a cross-sectional study of patients in spontaneous term labor who underwent amniocentesis (n = 101). The patients were divided into two study groups: (1) MSAF (n = 61) and (2) clear fluid (n = 40). The presence of bacteria and endotoxin as well as interleukin-6 (IL-6) and sPLA2 concentrations in the amniotic fluid were determined. Statistical analyses were performed to test for normality and bivariate analysis. The Spearman correlation coefficient was used to study the relationship between sPLA2 and IL-6 concentrations in the amniotic fluid. RESULTS Patients with MSAF have a higher median sPLA2 concentration (ng/mL) in amniotic fluid than those with clear fluid [1.7 (0.98-2.89) versus 0.3 (0-0.6), p < 0.001]. Among patients with MSAF, those with either microbial invasion of the amniotic cavity (MIAC, defined as presence of bacteria in the amniotic cavity), or bacterial endotoxin had a significantly higher median sPLA2 concentration (ng/mL) in amniotic fluid than those without MIAC or endotoxin [2.4 (1.7-6.0) versus 1.7 (1.3-2.5), p < 0.05]. There was a positive correlation between sPLA2 and IL-6 concentrations in the amniotic fluid (Spearman Rho = 0.3, p < 0.05). CONCLUSION MSAF that contains bacteria or endotoxin has a higher concentration of sPLA2, and this may contribute to induce lung inflammation when meconium is aspirated before birth.

Abstract
BACKGROUND Meconium-stained amniotic fluid (MSAF) is a common occurrence among women in spontaneous labor at term, and has been associated with adverse outcomes in both mother and neonate. MSAF is a risk factor for microbial invasion of the amniotic cavity (MIAC) and preterm birth among women with preterm labor and intact membranes. We now report the frequency of MIAC and the presence of bacterial endotoxin in the amniotic fluid of patients with MSAF at term. MATERIALS AND METHODS We conducted a cross-sectional study including women in presumed preterm labor because of uncertain dates who underwent amniocentesis, and were later determined to be at term (n = 108). Patients were allocated into two groups: (1) MSAF (n = 66) and (2) clear amniotic fluid (n = 42). The presence of bacteria was determined by microbiologic techniques, and endotoxin was detected using the Limulus amebocyte lysate (LAL) gel clot assay. Statistical analyses were performed to test for normality and bivariate comparisons. RESULTS Bacteria were more frequently present in patients with MSAF compared to those with clear amniotic fluid [19.6% (13/66) versus 4.7% (2/42); p < 0.05]. The microorganisms were Gram-negative rods (n = 7), Ureaplasma urealyticum (n = 4), Gram-positive rods (n = 2) and Mycoplasma hominis (n = 1). The LAL gel clot assay was positive in 46.9% (31/66) of patients with MSAF, and in 4.7% (2/42) of those with clear amniotic fluid (p < 0.001). After heat treatment, the frequency of a positive LAL gel clot assay remained higher in the MSAF group [18.1% (12/66) versus 2.3% (1/42), p < 0.05]. Median amniotic fluid IL-6 concentration (ng/mL) was higher [1.3 (0.7-1.9) versus 0.6 (0.3-1.2), p = 0.04], and median amniotic fluid glucose concentration (mg/dL) was lower [6 (0-8.9) versus 9 (7.4-12.6), p < 0.001] in the MSAF group, than in those with clear amniotic fluid. CONCLUSION MSAF at term was associated with an increased incidence of MIAC. The index of suspicion for an infection-related process in postpartum women and their neonates should be increased in the presence of MSAF.

Abstract
Maternity unit closures in France have increased travel time for pregnant women in rural areas. We assessed the impact of travel time to the closest unit on perinatal outcomes and care in Burgundy using multilevel analyses of data on deliveries from 2000 to 2009. A travel time of 30min or more increased risks of fetal heart rate anomalies, meconium-stained amniotic fluid, out-of-hospital births, and pregnancy hospitalizations; a positive but non-significant gradient existed between travel time and perinatal mortality. The effects of long travel distances on perinatal outcomes and care should be factored into closure decisions.

Abstract
OBJECTIVE To compare the risk of stillbirth and miscarriage in a subsequent pregnancy in women with a previous caesarean or vaginal delivery. DESIGN Systematic review of the published literature including seven databases: CINAHL; the Cochrane library; Embase; Medline; PubMed; SCOPUS and Web of Knowledge from 1945 until November 11(th) 2011, using a detailed search-strategy and cross-checking of reference lists. STUDY SELECTION Cohort, case-control and cross-sectional studies examining the association between previous caesarean section and subsequent stillbirth or miscarriage risk. Two assessors screened titles to identify eligible studies, using a standardised data abstraction form and assessed study quality. DATA SYNTHESIS 11 articles were included for stillbirth, totalling 1,961,829 pregnancies and 7,308 events. Eight eligible articles were included for miscarriage, totalling 147,017 pregnancies and 12,682 events. Pooled estimates across the stillbirth studies were obtained using random-effect models. Among women with a previous caesarean an increase in odds of 1.23 [95% CI 1.08, 1.40] for stillbirth was yielded. Subgroup analyses including unexplained stillbirths yielded an OR of 1.47 [95% CI 1.20, 1.80], an OR of 2.11 [95% CI 1.16, 3.84] for explained stillbirths and an OR of 1.27 [95% CI 0.95, 1.70] for antepartum stillbirths. Only one study reported adjusted estimates in the miscarriage review, therefore results are presented individually. CONCLUSIONS Given the recent revision of the National Institute for Health and Clinical Excellence guidelines (NICE), providing women the right to request a caesarean, it is essential to establish whether mode of delivery has an association with subsequent risk of stillbirth or miscarriage. Overall, compared to vaginal delivery, the pooled estimates suggest that caesarean delivery may increase the risk of stillbirth by 23%. Results for the miscarriage review were inconsistent and lack of adjustment for confounding was a major limitation. Higher methodological quality research is required to reliably assess the risk of miscarriage in subsequent pregnancies.

Abstract
PURPOSE We aimed in this research to explore factors contributing to the occurrence of intra-uterine fetal death (IUFD). METHODS The study was conducted between 1st January 2008 and 31st December 2009 in the Department of Obstetrics and Gynecology at King Abdulaziz Medical City, Riyadh, Saudi Arabia. Patients who were diagnosed to have IUFD at ≥24 weeks of gestation and those whose dead fetuses were found to weigh ≥500 g after delivery were eligible to be included. 138 patients with IUFD and 237 controls with alive fetuses were enrolled. Data were collected from printed and computerized medical records of participants. Factors that may have contributed to the occurrence of IUFD were explored. Comparisons between various risk factors and outcomes of the two groups were done. p value was statistically significant if ≤0.05. RESULTS Patients who did not receive antenatal care (ANC) services are at 70 % increased risk for developing IUFD (OR 0.31, p < 0.0001). Risk of IUFD increases 25-fold with the occurrence of abruption placenta (OR 25.81, p ≤ 0.0001), tenfolds with the occurrence of intra-uterine growth restrictions (OR 10.78, p = 0.04) and threefolds with the presence of hypertensive disorder in pregnancy (OR 3.17, p = 0.04). Finally, patients carrying IUFD fetuses are at higher risk to develop labor complications compared with their controls (p ≤ 0.0001). CONCLUSION Despite the difficulty in predicting IUFD occurrence, it appears that carefully implemented ANC and timely management of at risk patients may contribute to its prevention.
