Teenage pregnancy as a risk factor for placental abruption: Findings from the prospective Japan environment and children's study. PLoS One 2021; 16:e0251428. [PMID: 33984034 PMCID: PMC8118252 DOI: 10.1371/journal.pone.0251428] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2021] [Accepted: 04/26/2021] [Indexed: 11/18/2022] Open
Abstract
Objective Placental abruption is a significant obstetric complication that affects both maternal and neonatal mortality and morbidity. The present study examined the effect of maternal age on the incidence of placental abruption. Methods We used data of singleton pregnancies from the Japan Environment and Children’s Study, which was a prospective birth cohort study conducted between January 2011 and March 2014 across 15 regional centers in Japan. A multiple regression model was used to identify whether maternal age (<20 years, 20–24 years, 25–29 years, 30–34 years, and ≥35 years) is a risk factor for placental abruption. The analyses were conducted while considering the history of placental abruption, assisted reproductive technology, number of previous deliveries, smoking during pregnancy, body mass index before pregnancy, and chronic hypertension. Results A total of 94,410 Japanese women (93,994 without placental abruption and 416 with placental abruption) were recruited. Herein, 764, 8421, 25915, 33517, and 25793 women were aged <20 years, 20–24 years, 25–29 years, 30–34 years, and ≥35 years, respectively. Besides advanced maternal age (≥35 years; adjusted odds ratio: 1.7, 95% confidence interval: 1.1–2.5), teenage pregnancy was also a risk factor for placental abruption (adjusted odds ratio: 2.8, 95% confidence interval: 1.2–6.5) when the maternal age of 20–24 years was set as a reference. Conclusions In the Japanese general population, besides advanced maternal age, teenage pregnancy was associated with placental abruption. Recently, the mean maternal age has been changing in Japan. Therefore, it is important for obstetric care providers to provide proper counseling to young women based on up-to-date evidence.

Eur J Obstet Gynecol Reprod Biol 2020; 253:95-102. [PMID: 32862031 DOI: 10.1016/j.ejogrb.2020.07.018] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2020] [Revised: 06/30/2020] [Accepted: 07/10/2020] [Indexed: 11/29/2022]
Abstract
OBJECTIVE To investigate pregnant women from the Safe Passage Study for the individual and combined effects of smoking and drinking during pregnancy on the prevalence of clinical placental abruption. STUDY DESIGN The aim of the original Safe Passage Study was to investigate the association of alcohol use during pregnancy with stillbirths and sudden infant deaths. Recruitment for this longitudinal study occurred between August 2007 and October 2016. Information on smoking and drinking was collected prospectively at up to 4 occasions during pregnancy where a modified timeline follow-back method was used to assess the exposure to alcohol. Placentas were examined histologically in a subset of pregnant women. For this study we examined the effects of smoking and drinking on fetal growth and the prevalence rate of placental abruption. High smoking constituted of 10 or more cigarettes per day and high drinking of four or more binge drinking episodes or 32 and more standard drinks during pregnancy. Placental abruption was diagnosed in two ways, by the clinical picture or the macroscopic and microscopic examination of the placenta. RESULTS When compared to the non-drinking/non-smoking group, the high drinking/high smoking group were significantly older, had a higher gravidity, had a lower household income and booked later for prenatal care; fewer of them were employed and had toilet and running water facilities in their houses. Clinical placental abruption was diagnosed in 49 (0.87 %) of 5806 pregnancies. Histological examination was done in 1319 placentas; macroscopic and microscopic diagnosis of placental abruption was made in 8.2 % and 11.9 % of placentas respectively. These 49 cases were then correlated with seven smoking/drinking patterns during pregnancy. When compared to rates for no smoking/no drinking (0.11 %) and low smoking/no drinking (0.55 %), the prevalence rate of placental abruption was significantly higher (p < .005) in the low smoking/low drinking group (1.25 %). There was also a significant relationship between low maternal employment and methamphetamine use with placental abruption. CONCLUSION As many conditions and habits are associated with placental abruption, it is impossible to single out one specific cause but concomitant drinking and smoking seem to increase the risk of placental abruption.

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
Hypofibrinogenemia is rare in pulmonary thromboembolism. A pregnant woman with dyspnea, abdominal pain, restlessness, agitation and protein S deficiency exhibited normal blood oxygenation and high D-dimer (370 μg/mL) and undetectable fibrinogen levels in the blood. The pathogenesis responsible for present findings may have some features similar to amniotic fluid embolism.

Abstract
OBJECTIVE To evaluate the occurrence of severe obstetric complications associated with antepartum and intrapartum hemorrhage among women from the Brazilian Network for Surveillance of Severe Maternal Morbidity. DESIGN Multicenter cross-sectional study. SETTING Twenty-seven obstetric referral units in Brazil between July 2009 and June 2010. POPULATION A total of 9555 women categorized as having obstetric complications. METHODS The occurrence of potentially life-threatening conditions, maternal near miss and maternal deaths associated with antepartum and intrapartum hemorrhage was evaluated. Sociodemographic and obstetric characteristics and the use of criteria for management of severe bleeding were also assessed in these women. MAIN OUTCOME MEASURES The prevalence ratios with their respective 95% confidence intervals adjusted for the cluster effect of the design, and multiple logistic regression analysis were performed to identify factors independently associated with the occurrence of severe maternal outcome. RESULTS Antepartum and intrapartum hemorrhage occurred in only 8% (767) of women experiencing any type of obstetric complication. However, it was responsible for 18.2% (140) of maternal near miss and 10% (14) of maternal death cases. On multivariate analysis, maternal age and previous cesarean section were shown to be independently associated with an increased risk of severe maternal outcome (near miss or death). CONCLUSION Severe maternal outcome due to antepartum and intrapartum hemorrhage was highly prevalent among Brazilian women. Certain risk factors, maternal age and previous cesarean delivery in particular, were associated with the occurrence of bleeding.
