Life stressors, hypertensive disorders of pregnancy, and preterm birth.

ABSTRACT: Background: Stress-induced pregnancy complications are thought to represent a significant cause of maternal morbidity and mortality; little is known regarding types of stress most predictive of adverse outcomes.Methods: We used Utah PRAMs 2012-2014 data to evaluate links between preconception life stressors and prevalence of hypertensive disorders of pregnancy (HDP) and pre-term labor (PTB) (births <37 weeks gestational age, and very PTB <33 weeks). We categorized 12 specific stressful events into 4 groups: partner, traumatic, financial, and emotional. Adjusted prevalence ratios (aPRs) and 95% confidence intervals (CIs) were estimated controlling for important sociodemographic, lifestyle, and pregnancy history factors.Results: 4,378 mothers completed the survey. 26.6%, 12.2%, 32.2%, and 28.4% reported partner, traumatic, financial, and emotional-related stress. Reporting any of the 4-types of life stress was linked with increased prevalence of HDP (aPR: 1.46 [95% CI: 0.96, 2.22]) after adjusting for age, race/ethnicity, BMI, education, prior diagnosis of high blood pressure, and prior history of preterm labor. The strongest association was observed for financial stress (aPR: 1.50 [95% CI: 1.03, 2.18]). Financial stress was also associated with increased prevalence of very PTB (aPR: 1.61 [95% CI: 1.03, 2.51]) after adjustment.Conclusion: Women reporting financial stress, including job loss, pay reduction, or difficulty paying bills, had increased prevalence of HDP and very PTB.

Air Pollution, Maternal Hypertensive Disorders, and Preterm Birth.

Project description:Background:Air pollution has been associated with hypertension and preterm birth. We examined if prenatal exposure to air pollutants was associated with gestational hypertension and if its association with preterm birth was modified by maternal hypertension. Methods:Data were from birth certificates and hospital discharge records of 252,205 women in San Joaquin Valley of California from 2000-2006. Air quality data were assigned from 24-hour averages of nitrogen dioxide (NO2), particulate matter <10?m (PM10) and <2.5?m (PM2.5), and carbon monoxide (CO) for different averaging periods over pregnancy. We estimated odds of preterm birth and multiplicative interaction between each pollutant and hypertensive disorder. Results:Among normotensive women, odds of preterm birth were slightly higher for higher exposure to all pollutants over the entire pregnancy. Patterns were similar among women with a hypertensive disorder. Among 32-36 week births there was effect modification for exposure to NO2 and CO during the first trimester with higher odds among hypertensive women, and PM2.5 and CO during the last six weeks with higher odds among normotensive women. For 28-31 week births, there was effect modification by hypertensive status for PM10 exposure for entire pregnancy, first, and second trimester with hypertensive women consistently having lower odds of preterm birth than normotensive. Conclusion:There was some evidence of effect modification in the direction counter to our hypothesis for exposure to PM10 and early preterm birth, and CO and PM2.5 at the end of pregnancy, but overall, hypertension did not modify the relationship between pollution and preterm birth.

Hypertensive Disorders of Pregnancy - A Life-Long Risk?!

Project description:Background: Arterial hypertension is one of the most important causes of cardiovascular diseases, and the latter are responsible for almost half of the deaths in the industrialised nations. Hypertensive disorders of pregnancy constitute one of the most frequent causes of feto-maternal morbidity and mortality; on the other hand the occurrence of a hypertensive disorder of pregnancy represents a risk for the later development of hypertension and the cardiovascular risks resulting therefrom. The aim of this article is to demonstrate the association of hypertensive disorders of pregnancy with consecutive cardiovascular diseases. Materials and Methods: Specific selective literature research. Results: After the occurrence of a hypertensive disorder of pregnancy the relative risks for hypertension are 3.7 (2.70-5.05), for ischaemic heart disease 2.2 (1.86-2.52), for cerebral insult 1.8 (1.45-2.27) and for mortality resulting from cardiovascular causes 1.5 (1.05-2.14) and are thus significant. According to a recent study 56?% of internal specialists and 23?% of gynecologists do not know about the association of preeclampsia with ischemic heart disease, 48?% and 38?% respectively are not aware of the link with stroke and 79?% and 77?% respectively are not aware of the association with a reduced life expectancy after preeclampsia. The presence of hypertension is not known by many of the patients, merely 28-38?% receive an appropriate therapy. Conclusion: Adequate follow-up after hypertensive disorders of pregnancy and the early recognition of and therapy for hypertension represent the cornerstones in the prevention of late cardiovascular sequelae. General practitioners, specialist for internal medicine and gynaecologists have a special responsibility with regard to the reduction of later complications.

Fetal exposure to herpesviruses may be associated with pregnancy-induced hypertensive disorders and preterm birth in a Caucasian population.

Project description:OBJECTIVE:To investigate the role of fetal viral infection in the development of a range of adverse pregnancy outcomes (APOs), including pregnancy-induced hypertensive disorders (PIHD), antepartum haemorrhage (APH), birthweight <10th percentile (small for gestational age, SGA) and preterm birth (PTB). DESIGN:Population-based case-control study. SETTING:Laboratory-based study. POPULATION:The newborn screening cards of 717 adverse pregnancy cases and 609 controls. METHODS:Newborn screening cards were tested for RNA from enteroviruses and DNA from herpesviruses using polymerase chain reaction (PCR). The herpesviruses were detected using two PCRs, one detecting nucleic acids from herpes simplex virus (HSV)-1, HSV-2, Epstein-Barr virus (EBV), cytomegalovirus (CMV) and human herpesvirus (HHV)-8, hereafter designated Herpes PCR group A viruses, and the other detecting nucleic acids from varicella-zoster virus (VZV), HHV-6 and HHV-7, hereafter designated Herpes PCR group B viruses. MAIN OUTCOME MEASURE:Odds ratios and 95% CIs for specific APOs. RESULTS:For both term and PTBs, the risk of developing PIHD was increased in the presence of DNA from Herpes PCR group B viruses (OR 3.57, 95% CI 1.10-11.70), CMV (OR 3.89, 95% CI 1.67-9.06), any herpesvirus (OR 5.70, 95% CI 1.85-17.57) and any virus (OR 5.17, 95% CI 1.68-15.94). The presence of CMV was associated with PTB (OR 1.61, 95% CI 1.14-2.27). No significant association was observed between SGA or APH and exposure to viral infection. CONCLUSIONS:Fetal exposure to herpesvirus infection was associated with PIHD for both term and PTBs in this exploratory study. Exposure to CMV may also be associated with PTB. These findings need confirmation in future studies.

Latency of preterm hypertensive disorders of pregnancy and subsequent cardiovascular complications.

Project description:ObjectivesTo test the hypothesis that increasing latency from diagnosis to delivery in patients with preterm hypertensive disorders of pregnancy is associated with an increased maternal risk of cardiovascular admission after delivery.Study designRetrospective cohort from the IBM MarketScan® Commercial Database from 2006 to 2016. Patients age 15-45 years with a preterm delivery complicated by a hypertensive disorder of pregnancy, at least 6 months of continuous insurance coverage prior to delivery and at least 365 days of coverage post-delivery were included.Main outcome measuresHospital readmission after delivery for a composite of acute cardiovascular events (cardiomyopathy, heart failure, cardiac arrest, myocardial infarction) or cerebrovascular events. Cox proportional hazards were used to estimate the risk of the primary outcome for each week of latency from diagnosis to delivery.ResultsThere were 34,989 women in the study with a median follow-up of 2.57 years (IQR 1.66 to 1.54 years) with a median time from diagnosis to delivery of three days (IQR 0 to 14 days). An increasing time from diagnosis to delivery was associated with an increased risk of an acute cardiovascular event (adjusted HR 1.06, 95% CI 1.01, 1.11 per week), in models adjusted for maternal comorbidities and demographic factors. Later gestational age at diagnosis was associated with a decreased risk of maternal cardiovascular admission after delivery (aHR 0.94, 95% CI 0.91, 0.98 for each week increase in gestational age).ConclusionsProlonging expectant management of preterm hypertensive disorders of pregnancy is associated with an increased risk of maternal cardiovascular disease after delivery.

Hypertensive Disorders of Pregnancy.

Project description:Hypertension is the most common medical disorder occurring during pregnancy and a leading cause of maternal and perinatal morbidity and mortality. Accurate blood pressure measurement and the diagnosis and treatment of hypertensive disorders during pregnancy and in the postpartum period are pivotal to improve outcomes. This article details hemodynamic adaptations to pregnancy and provides an approach to the prevention, diagnosis, and management of hypertensive disorders of pregnancy (HDP) and hypertensive emergencies. In addition, it reviews optimal strategies for the care of women with hypertension during the fourth trimester and beyond to minimize future cardiovascular risk.

Antenatal corticosteroids and preterm offspring outcomes in hypertensive disorders of pregnancy: A Japanese cohort study.

Project description:To estimate whether antenatal corticosteroids (ACS) improve short- and long-term preterm offspring outcomes in singleton pregnancies complicated by hypertensive disorders of pregnancy (HDP) similar to pregnancies without HDP. This population-based retrospective study was conducted based on an analysis of data collected by the Neonatal Research Network of Japan on 21,014 singleton neonates weighing ?1,500?g between 24 and 31 weeks' gestation during 2003-2016. Logistic regression analyses were performed to compare short- and long-term offspring outcomes between mothers receiving ACS treatment and those who did not among pregnancies with HDP and without HDP. Of 21,014 neonates, 4,806 (22.9%) were born to mothers with HDP. ACS treatment was associated with significant decreases in short-term adverse outcomes in the both HDP and non-HDP groups, with similar reduced odds of neonatal death, respiratory distress syndrome, and intraventricular haemorrhage (IVH). However, ACS treatment did not significantly decrease severe IVH (aOR 0.76; 95% CI 0.51-1.13) and periventricular leukomalacia (1.14; 0.78-1.66) in the HDP group. In addition, ACS treatment in mothers without HDP significantly decreased cerebral palsy (aOR 0.70; 95% CI 0.58-084), developmental quotient scores <85 (0.79; 0.69-0.90), and composite adverse outcomes (0.85; 0.75-0.96) at 3 years of age, whereas ACS treatment in mothers with HDP did not significantly improve these outcomes (1.04; 0.69-1.57, 1.11; 0.88-1.39, 0.96; 0.75-1.22, respectively). ACS treatment was associated with significantly decreased major short-term morbidities and mortality among extremely and very preterm neonates of mothers with HDP, with ACS treatment having a decreased effect compared to that observed in neonates of mothers without HDP. Although ACS treatment has no additional effects on offspring outcomes at 3 years of age, our results did not suggest that ACS treatment should be withheld from mothers with HDP.

Spontaneous preterm birth prevention in multiple pregnancy.

Project description:Twin pregnancies are associated with a three-fold greater perinatal mortality than singleton pregnancies. Prematurity is a main contributor, with 50% of twin pregnancies delivering before 37 weeks and 10% delivering before 32 weeks of gestation.The aetiology of preterm delivery in twin pregnancies is likely multifactorial and different from that of singletons.Cervical cerclage reduces preterm birth rates in singletons but has mixed results in twins with some studies showing harm.The use of progesterone to prevent preterm birth in singletons has conflicting results and has not been proven to prevent preterm birth in twins. Studies continue to determine whether the cervical pessary is effective in preventing preterm birth in multiple pregnancies.There is a paucity of data available on the prevention of preterm birth in triplets/higher order multiples but similar principles to twin pregnancy apply.To review the burden of preterm birth in multiple pregnancy.To understand the methods available for preventing preterm birth in multiple pregnancies and the evidence surrounding the use of each one.To be aware of the use of the Arabin pessary.

Hypertensive Disorders of Pregnancy and Medication Use in the 2015 Pelotas (Brazil) Birth Cohort Study.

Project description:Hypertensive disorders of pregnancy account for approximately 22% of all maternal deaths in Latin America and the Caribbean. Pharmacotherapies play an important role in preventing and reducing the occurrence of adverse outcomes. However, the patterns of medications used for treating women with hypertensive disorders of pregnancy (HDP) living in this country is unclear. A population-based birth cohort study including 4262 women was conducted to describe the pattern of use of cardiovascular agents and acetylsalicylic acid between women with and without HDP in the 2015 Pelotas (Brazil) Birth Cohort. The prevalence of maternal and perinatal outcomes in this population was also assessed. HDP were classified according to Ministry of Health recommendations. Medications were defined using the Anatomical Therapeutic Chemical Classification System and the substance name. In this cohort, 1336 (31.3%) of women had HDP. Gestational hypertension was present in 636 (47.6%) women, 409 (30.6%) had chronic hypertension, 191 (14.3%) pre-eclampsia, and 89 (6.7%) pre-eclampsia superimposed on chronic hypertension. Approximately 70% of women with HDP reported not using any cardiovascular medications. Methyldopa in monotherapy was the most frequent treatment (16%), regardless of the type of HDP. Omega-3 was the medication most frequently reported by women without HDP. Preterm delivery, caesarean section, low birth weight, and neonatal intensive care admissions were more prevalent in women with HDP. Patterns of use of methyldopa were in-line with the Brazilian guidelines as the first-line therapy for HDP. However, the large number of women with HDP not using medications to manage HDP requires further investigation.

Risk of cerebral palsy in relation to pregnancy disorders and preterm birth: a national cohort study.

Project description:To assess the risk of developing cerebral palsy in relation to pregnancy disorders and preterm birth.By linking the Medical Birth Registry of Norway to other national registries, we identified all live births in Norway from 1967 through to 2001. Risks of cerebral palsy (CP) after preterm delivery and pregnancy disorders were estimated in different gestational age groups.In total, 1 764 509 children delivered at 23 to 43 weeks' gestation were included. The prevalence of CP was 1.8 per 1000 births. Absolute risk of CP was 8.5% among children born at 23 to 27 weeks' gestation, 5.6% at 28 to 30 weeks, 2.0% at 31 to 33 weeks, 0.4% at 34 to 36 weeks, and 0.1% thereafter. Placental abruption, chorioamnionitis, prolonged rupture of membranes, intrauterine growth restriction, pre-eclampsia, multiple births, placenta previa, bleeding, cervical conization, and congenital malformation were all associated with CP. Before 32 weeks' gestation, absolute risk of CP was highest with chorioamnionitis (9.1%) and lowest with pre-eclampsia (3.1%). Among those born after 31 weeks, the absolute risk of CP was more consistently (but also more slightly) increased with a recorded pregnancy disorder.Early delivery and pregnancy disorders were both strong risk factors for CP. The added risks with recorded pregnancy disorders varied within categories of gestational age.
