Association between maternal anxiety in pregnancy and increased uterine artery resistance index: cohort based study

Optimizing Psychological Health Across the Perinatal Period: An Update on Maternal Cardiovascular Health: A Scientific Statement From the American Heart Association

Perinatal psychological health conditions (eg, perinatal depression, anxiety) are some of the leading causes of maternal mortality in the United States and are associated with adverse pregnancy outcomes, long-term cardiovascular outcomes, and intergenerational effects on offspring neurodevelopment. These risks underscore the importance of addressing maternal psychological health as a key determinant of perinatal cardiovascular health. Thus, it is vital to recognize the spectrum of perinatal psychological health and to provide guidance for both patients and clinicians on screening and management options across the perinatal period. In this scientific statement from the American Heart Association, we redefine maternal cardiovascular health to include psychological health, provide robust evidence on the association of psychological health with cardiovascular outcomes, highlight the social and environmental underpinnings, and finally, offer guidance about how to integrate psychological health into maternal cardiovascular health with a specific focus on the perinatal period (ie, pregnancy through 1 year postpartum). We also describe opportunities for creating care delivery models that recurrently address perinatal psychological health in cardio-obstetric care, using behavioral and pharmacological interventions, with an emphasis on better integration of psychological health care, longer postpartum follow-up, and opportunities for evaluating the comparative effectiveness of these models with stakeholder partners.

Computerized cardiotocography and fetal heart response to maternal coffee intake: a prospective study

BACKGROUND

The aim of this study was to determine the effect of caffeine on fetal heart rate (FHR) as determined by computerized cardiotocography (cCTG) parameters.

METHODS

Term pregnancies that performed a fetal antepartum cCTG were included. Two physicians recorded coffee habits before the cCTG, and pregnant women were divided into two groups: the coffee group and the control group. Furthermore, cCTG' parameters were compared between the two groups.

RESULTS

One hundred thirty-four pregnant women were enrolled. Based on maternal coffee habits, 82 pregnant women were allocated to the coffee group, while 52 were in the control group. The two groups shared similar demographic and obstetric characteristics. The mean daily coffee intake was 1.4±0.6 cups. Coffee group fetuses evidenced a lower FHR baseline, 135±9.9 bpm, versus the control group, 138±8.0 bpm, (P value = 0.03). Other cCTG parameters did not show statistical differences. Multivariate analysis demonstrated no confounding factors. A subanalysis that evaluated the daily amount of coffee consumed or the half-life of caffeine found no difference in cCTG measures.

CONCLUSIONS

Maternal caffeine consumption did not influence fetal cardiac reactivity after absorption.

Panic disorder during pregnancy and the first three years after delivery: a systematic review

BACKGROUND

Panic disorder (PD) is highly prevalent during the peripartum period. The aim of this systematic review was to summarize evidence on risk factors and course patterns of peripartum PD as well as maternal, infant or dyadic outcomes during the first three years after delivery.

METHODS

A literature search was conducted according to PRISMA guidelines. Inclusion criteria were: (1) a diagnosis of PD or panic attacks during pregnancy, (2) risk factors and course as well as maternal, infant or dyadic outcomes measured in pregnancy and/or up to 3 years postpartum (3) peer-reviewed articles in English or German published between 1980 and April 2024. After screening of n = 2,740 records, n = 75 records based on n = 64 projects were eligible for this systematic review.

RESULTS

Overall, n = 47 studies investigated the course of PD during the peripartum period, n = 23 studies examined the associations of PD and obstetric, neonatal or infant outcomes, and n = 5 studies focused on the associations of PD and characteristics of the mother-infant dyad. We found (1) no common trajectory, but heterogeneous courses of maternal PD in the peripartum period, (2) associations of maternal PD with birth complications and subsequent postpartum depression, and (3) evidence for associations of PD with infant and dyadic outcomes.

LIMITATIONS

Diverse outcome measures in recent original publications did not allow for a meta-analytic approach.

CONCLUSION

Heterogenous courses and outcomes of peripartum PD require comprehensive monitoring of affected mothers and their infants. There is a need for further longitudinal investigations into familial transmission of anxiety disorders.

The association between perinatal depressive symptoms and child neurodevelopment

BACKGROUND

Perinatal depression has been suggested to adversely impact child neurodevelopment. However, the complexity of the early childhood environment challenges conclusive findings.

OBJECTIVE

To evaluate whether there is an association between perinatal depressive symptoms and child intelligence quotient (IQ) at 5 years of age.

STUDY DESIGN

Secondary analysis of an ancillary study to a multicenter randomized trial of thyroxine therapy for pregnant individuals with subclinical hypothyroidism. Dyads of infants and birthing parent, with completed Center for Epidemiological Studies-Depression (CES-D) screens during pregnancy and postpartum and child neurodevelopment testing completed at five years of age (n=209) were included. CES-D screening was performed at 11-20 weeks, 34-38 weeks, and one-year postpartum. Depressive symptoms were categorized as antenatal (i.e., a positive screen at any point during pregnancy) or postpartum. The primary outcome was child IQ score < 85 at 5 years of age using the Wechsler Preschool and Primary Scale of Intelligence III (WPPSI-III) Full Scale test. Secondary outcomes included other assessments of childhood neurodevelopment. Bivariable analyses and multivariable logistic regressions were utilized.

RESULTS

Of the 209 birthing people included, 72 (34%) screened positive for depression during pregnancy and 32 (15%) screened positive one year postpartum. Children born to individuals with a positive antenatal depression screen had a higher odds of IQ < 85 at 5 years of age compared with children born to individuals with a CES-D < 16 (35% vs. 18%, OR 2.4, 95% CI 1.2-4.7). Similar findings were seen for children born to individuals with a positive postpartum depression screen (47% vs. 21%, OR 3.3, 95% CI 1.5-7.3). These associations did not persist in multivariable analyses that controlled for social determinants of health and clinical characteristics (adjusted odd ratio [aOR] 1.4, 95% CI 0.7-3.1; aOR 2.1, 95% CI 0.9-5.1, for antenatal and postpartum depressive symptoms, respectively). Similar findings were observed for other adverse neurodevelopmental outcomes.

CONCLUSIONS

Having a positive perinatal depression screen was not associated with child cognitive outcomes after controlling for covariates including social determinants of health.

Brain structural and functional outcomes in the offspring of women experiencing psychological distress during pregnancy

In-utero exposure to maternal psychological distress is increasingly linked with disrupted fetal and neonatal brain development and long-term neurobehavioral dysfunction in children and adults. Elevated maternal psychological distress is associated with changes in fetal brain structure and function, including reduced hippocampal and cerebellar volumes, increased cerebral cortical gyrification and sulcal depth, decreased brain metabolites (e.g., choline and creatine levels), and disrupted functional connectivity. After birth, reduced cerebral and cerebellar gray matter volumes, increased cerebral cortical gyrification, altered amygdala and hippocampal volumes, and disturbed brain microstructure and functional connectivity have been reported in the offspring months or even years after exposure to maternal distress during pregnancy. Additionally, adverse child neurodevelopment outcomes such as cognitive, language, learning, memory, social-emotional problems, and neuropsychiatric dysfunction are being increasingly reported after prenatal exposure to maternal distress. The mechanisms by which prenatal maternal psychological distress influences early brain development include but are not limited to impaired placental function, disrupted fetal epigenetic regulation, altered microbiome and inflammation, dysregulated hypothalamic pituitary adrenal axis, altered distribution of the fetal cardiac output to the brain, and disrupted maternal sleep and appetite. This review will appraise the available literature on the brain structural and functional outcomes and neurodevelopmental outcomes in the offspring of pregnant women experiencing elevated psychological distress. In addition, it will also provide an overview of the mechanistic underpinnings of brain development changes in stress response and discuss current treatments for elevated maternal psychological distress, including pharmacotherapy (e.g., selective serotonin reuptake inhibitors) and non-pharmacotherapy (e.g., cognitive-behavior therapy). Finally, it will end with a consideration of future directions in the field.

High Anxiety Levels before Elective Cesarean Section Can Negatively Affect the Mother and Fetus

BACKGROUND

Both pregnancy and surgery cause anxiety. This situation may negatively affect the health of the mother and baby.

AIM

The effect of anxiety level before cesarean section (CS) on feto-maternal outcomes was investigated.

METHODS

The preoperative anxiety score was determined with the State-Trait Anxiety Inventory (STAI) in 224 pregnant women who were planned for elective CS.

RESULTS

Among patients, 33.5% were in the low anxiety group, 27.2% in the moderate, and 39.3% in the high anxiety group. The average birth weight in the low anxiety group was noticeably higher than that of the high anxiety group (P = 0.018). The mean heart rate at postop 1st and 24th hour in the high anxiety group was higher than the moderate anxiety group (P < 0.028). In addition, diastolic blood pressure (DBP) at the sixth hour in the low anxiety group was found to be lower than in the moderate anxiety group (P < 0.05).

CONCLUSION

According to these results, it was found that an increased anxiety score before CS is associated with low birth weight in the baby, higher heart rate, and DBP in the mother.

Depression Treatment in Pregnancy: Is It Safe, or Is It Not?

Prenatal depression carries substantial risks for maternal and fetal health and increases susceptibility to postpartum depression. Untreated depression in pregnancy is correlated with adverse outcomes such as an increased risk of suicidal ideation, miscarriage and neonatal growth problems. Notwithstanding concerns about the use of antidepressants, the available treatment options emphasize the importance of specialized medical supervision during gestation. The purpose of this paper is to conduct a brief literature review on the main antidepressant drugs and their effects on pregnancy, assessing their risks and benefits. The analysis of the literature shows that it is essential that pregnancy be followed by specialized doctors and multidisciplinary teams (obstetricians, psychiatrists and psychologists) who attend to the woman's needs. Depression can now be treated safely during pregnancy by choosing drugs that have no teratogenic effects and fewer side effects for both mother and child. Comprehensive strategies involving increased awareness, early diagnosis, clear guidelines and effective treatment are essential to mitigate the impact of perinatal depression.

Preconception maternal retinal arteriolar narrowing and fetal growth throughout pregnancy: A prospective cohort study

OBJECTIVE

To investigate the association between preconception maternal retinal arteriolar calibre and fetal growth.

DESIGN, SETTING AND POPULATION

A hospital-based, prospective preconception cohort including 369 women with a singleton live birth.

METHODS

We collected detailed information on sociodemographic status, pregnancy history and lifestyle, and performed retinal imaging at the preconception visit.

MAIN OUTCOME MEASURES

We retrieved medical records documenting fetal growth biometrics (e.g., abdominal circumference [AC], head circumference [HC], femur length [FL]) at 11-13, 18-21, 24-28, and 32-34 weeks throughout pregnancy. We then computed the z scores for all fetal growth biometrics from 14 weeks of gestation where data were available, referencing the INTERGROWTH-21st fetal growth chart. We used a linear mixed model to estimate the association between maternal preconception retinal arteriolar calibre and fetal growth biometrics z scores throughout pregnancy, with random intercept accounting for repeated measures within individuals. We then performed a multivariable linear regression of maternal preconception retinal arteriolar calibre and z score changes for all fetal growth biometrics between 24-28 weeks and 32-34 weeks of gestation, after full adjustment.

RESULTS

Maternal preconception generalised retinal arteriolar narrowing was consistently associated with a reduction in fetal AC z scores (-0.34; 95% CI -0.66 to -0.03) throughout pregnancy. In addition, women with preconception generalised retinal arteriolar narrowing tended to have significantly reduced z score changes in AC (-0.41; 95% CI -0.90 to -0.001) and fetal FL (-0.55; 95% CI -1.00 to -0.10) between 24-28 weeks and 32-34 weeks of gestation, respectively.

CONCLUSIONS

Our findings suggest that women with narrower preconception retinal arterioles had smaller fetuses, evidenced by reductions in AC and FL z score throughout pregnancy.

Effect of emotional freedom technique on the fear of childbirth in Iranian primiparous women: a randomized controlled trial

Background

Fear of childbirth is one of the main causes of women's emotional difficulty experienced in the perinatal period, especially those having their first child.

Objective

The aim of this study was to investigate the effect of emotional freedom technique (EFT) on the fear of childbirth among primiparous women in Ahvaz, Iran.

Materials and methods

This randomized clinical trial was conducted on 116 primiparous women. The participants were randomly divided into intervention (n = 58) or control (n = 58) groups. The intervention group received daily stimulation of certain points in their body for 12 weeks using EFT. The fear of childbirth was measured at the beginning of the study and 12 weeks after the intervention using the Wijma Delivery Expectancy/Experience Questionnaire (WDEQ-A) and at the first postpartum visit with WDEQ-B. Data were analyzed using independent t-test, paired t-test, Chi-square or Fisher's exact test, and analysis of covariance (ANCOVA).

Results

After intervention, the mean score of fear of childbirth in the intervention group decreased from 49.39 ± 8.21 to 40.42 ± 13.43 (p < 0.0001), while the same rate in the control group increased from 49.47 ± 9.06 to 52.09 ± 7.73 (p = 0.002). The mean score of fear of childbirth after delivery in the control group (45.88 ± 7.10) was higher than that in the intervention group (27.13 ± 5.08) (p < 0.0001).

Conclusion

Based on the findings of this study, EFT can be considered as an effective method to reduce the fear of childbirth score in primiparous women.

Preconception maternal retinal venular widening and steeper resistance increments in the utero-fetoplacental circulation in pregnancy

We investigated the relationship of preconception maternal retinal vasculature and utero-fetoplacental circulation in ensuing pregnancy. Embedded in a hospital-based, prospective preconception cohort, 396 women with a singleton live birth were included for analysis. We assessed retinal vascular caliber during preconception phase and retrieved ultrasonogram results documenting utero-fetoplacental circulatory indices using Doppler ultrasonography and documented them at 18-21 weeks, 24-28 weeks, and 32-34 weeks where available. We performed a modified Poisson regression to estimate the relative risk of utero-fetoplacental abnormalities, adjusting for major confounders including pre-pregnancy and blood pressure. Per 10 μm increment in maternal preconception retinal venules was associated with over two-fold risks in developing notching (Relative risk [RR]: 2.84; 95% confidence interval [CI]: 1.79, 4.81) and ≥95th percentile umbilical artery pulsatility index (2.36; 1.72, 3.23) during mid-to-late pregnancy, respectively. Women with preconception retinal venular widening tended to demonstrate steeper resistance increments in both maternal uterine arteries and fetal umbilical arteries during mid-to-late pregnancy.

Psychological distress during pregnancy and adverse maternal and perinatal health outcomes: The role of socioeconomic status

OBJECTIVE

To study the contribution of socioeconomic status (SES) to the prevalence of psychological distress during pregnancy, and to investigate the association between psychological distress and maternal and perinatal health among different SES groups.

METHODS

This study was embedded in the Generation R study. Multiple self-reported questionnaires were used to measure psychological distress. Prevalence differences between SES groups were tested with the χ2 test. Linear and logistic regression analyses were used to examine the associations between psychological distress and maternal and perinatal health outcomes.

RESULTS

Women of low SES experience symptoms of psychopathology distress 4.5 times as often and symptoms of stress 2.5 times as often as women with of high SES. Women of low SES experiencing symptoms of psychopathology are at greater risk of delivering preterm. We also found associations between psychological distress and adverse perinatal health outcomes among women of middle and high SES.

CONCLUSION

The present study shows that the associations between SES, psychological distress, and maternal and perinatal health are complex, but do exist. To provide a better understanding of these associations, it is important to include mental health information in the standard national data collection on pregnant women, as this allows population-based studies.

The COVID-19 pandemic affects pregnancy complications and delivery outcomes in Japan: a large-scale nationwide population-based longitudinal study

The impact of the coronavirus disease 2019 (COVID-19) pandemic on pregnancy outcomes in Japan at the national level is unclear. This study aimed to assess the impact of the pandemic on pregnancy complications and delivery outcomes in Japan using nationwide population-based longitudinal data. Secondary data from the Japan Society of Obstetrics and Gynecology from 2016 to 2020 were analyzed. Obstetric information, pregnancy complications, and delivery information of pregnant women over 22 weeks of gestation were compared before and during the pandemic. The trends of hypertensive disorder of pregnancy, fetal growth restriction, and APGAR < 7 increased, whereas those of preterm birth and low birth weight decreased during the COVID-19 pandemic. Pregnancy complications and delivery outcomes have worsened during the COVID-19 pandemic in Japan. Social changes caused by unprecedented situations may have massively influenced pregnancy in several ways. Our findings suggest that even in mild lockdowns like those in Japan, the introduction of social fear during the pandemic might negatively impact pregnancy outcomes.

Consensus Panel Recommendations for the Pharmacological Management of Pregnant Women with Depressive Disorders

INTRODUCTION

The initiative of a consensus on the topic of antidepressant and anxiolytic drug use in pregnancy is developing in an area of clinical uncertainty. Although many studies have been published in recent years, there is still a paucity of authoritative evidence-based indications useful for guiding the prescription of these drugs during pregnancy, and the data from the literature are complex and require expert judgment to draw clear conclusions.

METHODS

For the elaboration of the consensus, we have involved the scientific societies of the sector, namely, the Italian Society of Toxicology, the Italian Society of Neuropsychopharmacology, the Italian Society of Psychiatry, the Italian Society of Obstetrics and Gynecology, the Italian Society of Drug Addiction and the Italian Society of Addiction Pathology. An interdisciplinary team of experts from different medical specialties (toxicologists, pharmacologists, psychiatrists, gynecologists, neonatologists) was first established to identify the needs underlying the consensus. The team, in its definitive structure, includes all the representatives of the aforementioned scientific societies; the task of the team was the evaluation of the most accredited international literature as well as using the methodology of the "Nominal Group Technique" with the help of a systematic review of the literature and with various discussion meetings, to arrive at the drafting and final approval of the document.

RESULTS

The following five areas of investigation were identified: (1) The importance of management of anxiety and depressive disorders in pregnancy, identifying the risks associated with untreated maternal depression in pregnancy. (2) The assessment of the overall risk of malformations with the antidepressant and anxiolytic drugs used in pregnancy. (3) The evaluation of neonatal adaptation disorders in the offspring of pregnant antidepressant/anxiolytic-treated women. (4) The long-term outcome of infants' cognitive development or behavior after in utero exposure to antidepressant/anxiolytic medicines. (5) The evaluation of pharmacological treatment of opioid-abusing pregnant women with depressive disorders.

CONCLUSIONS

Considering the state of the art, it is therefore necessary in the first instance to frame the issue of pharmacological choices in pregnant women who need treatment with antidepressant and anxiolytic drugs on the basis of data currently available in the literature. Particular attention must be paid to the evaluation of the risk/benefit ratio, understood both in terms of therapeutic benefit with respect to the potential risks of the treatment on the pregnancy and on the fetal outcome, and of the comparative risk between the treatment and the absence of treatment; in the choice prescription, the specialist needs to be aware of both the potential risks of pharmacological treatment and the equally important risks of an untreated or undertreated disorder.

The Impact of COVID-19-Related Psychological Stress on Fetoplacental Circulation: A Doppler Scan of Umbilical Vessels in Third-Trimester Antenatal Women

INTRODUCTION

The placenta is an important organ of pregnancy. A multitude of physiological and pathological factors influence blood flow in the placenta during pregnancy. However, the fetal effects of maternal psychological stress were inconclusive. The recent COVID-19 pandemic had unprecedented economic, social, and psychological effects. The effect of COVID-19-induced psychological stress in antenatal women and its resultant fetal impact were studied by observing the Doppler waveforms of the uterine and umbilical arteries.

METHODS

The cross-sectional study was conducted on 26 healthy third-trimester antenatal women who satisfied pre-set inclusion and exclusion criteria. A pandemic-related pregnancy stress scale (PREPS) was used to evaluate the stress in pregnant women and categorize it into mild, moderate, and severe levels. The Doppler ultrasound of the uterine and umbilical vessels was done along with a routine growth scan in the third trimester of pregnancy. The arterial waveforms, Pulsatility index (PI) of uterine and umbilical arteries, umbilical vein blood flow, and biometric parameters of the fetus were recorded and analyzed.

RESULTS

Seventeen of the 26 participants were found to be moderately stressed. Among the three dimensions of the PREPS tool, the perinatal infection stress dimension was expressed predominantly. A strong expression of the positive affirmation dimension was seen in antenatal women. The mean Pulsatility index in the mild, moderate, and severe groups was 0.74, 0.93, and 0.63, respectively. The association between the PREPS score and the Pulsatility index of the umbilical artery alone was found to be significant at p=0.02.

CONCLUSION

The COVID-19 pandemic caused moderate to severe levels of psychological stress in pregnant women. The statistically significant association between the PREPS score and the umbilical artery PI indicates possible fetoplacental compromise, suggesting the need for cognitive therapy to manage psychological stress in antenatal women.

Anxiety and Uterine Artery Doppler Flow in A Population of Pregnant Women of High Risk Down Syndrome Fetus: A Prospective Cohort Study

BACKGROUND

Fetal exposure to maternal anxiety is associated with low birth weight and maternal stress may be led to constriction of uterine arteries. This study compared the relation of anxiety and uterine artery doppler flow indices in pregnant women with the high and low-risk of Down syndrome.

MATERIALS AND METHODS

This prospective cohort study was conducted among pregnant women in the second trimester that were classified as having a high or low risk according to their prenatal aneuploidy screening outcome. The high risk group underwent amniocentesis. Anxiety was initially assessed using the Spielberger State-Anxiety Inventory (STAI) and uterine artery blood flow indices were evaluated 2 times for the both groups. For the high-risk group first: immediately before amniocentesis and second: after two weeks follow up, when receiving the karyotype results and for the low-risk group in the first admission and two weeks later.

RESULTS

Totally, 375 pregnant women participated in our study that sorted into 2 risk populations based on the aneuploidy screening test, low-risk=176 and high-risk women=199. The high-risk group for Down syndrome amniocentesis showed abnormal results in the 23 cases (23/199). The mean state (P=0.003) and trait (P=0.033) of the Anxiety Inventory scores were significantly different between the groups. Baseline uterine artery indices were no significant difference between the groups. Baseline Uterine artery indices in the high-risk group was significantly different with follow-up (in both positive-amniocentesis and negative amniocentesis sub-groups) indices. Also, there was a weak and significant correlation in the uterine resistance index and STAI scores (P=0.008, r=0.137) during the follow-up period.

CONCLUSION

All pregnant women experienced high level anxiety, especially in the high-risk group that may reduce after confirmation of prenatal aneuploidy screening test and also affects the Doppler indices. For all pregnant women; Stress management and emotional support training is recommended before and during pregnancy.

Pregnancy outcomes and anxiety in nulliparous women

OBJECTIVE

To examine pregnancy outcomes in women with treated and untreated anxiety in a well-characterized cohort.

STUDY DESIGN

Secondary analysis of the NuMoM2b study, a prospective multi-center cohort of nulliparous women. Anxiety was assessed at 6 weeks 0 days - 13 weeks 6 days using the State Trait Anxiety Inventory (STAI-T). Women were divided into three groups: anxiety and medical treatment, anxiety and no medical treatment, and no anxiety (controls). The primary outcome was a composite of preterm birth, small for gestational age infant, placental abruption (clinically diagnosed), and hypertensive disorders of pregnancy. Multivariable logistic regression was used to adjust for potential confounding variables.

RESULTS

Among 8293 eligible women, 24% (n = 1983) had anxiety; 311 were treated medically. The composite outcome (preterm birth, small for gestational age infant, placental abruption, hypertensive disorders of pregnancy) occurred more often in women with untreated anxiety than controls (28.6% vs 25.9%, p=.02), with no difference between treated anxiety and controls (27.7% vs 25.9%, p=.49). After adjustment for confounders, including controlling for depression, there were no differences in the primary outcome among groups. Untreated anxiety remained associated with increased odds of neonatal intensive care unit admission.

CONCLUSION

Anxiety occurred in almost a quarter of nulliparas. There was no association between treated or untreated anxiety and our primary outcome of adverse pregnancy outcomes after adjustment for confounders. However, neonates born to women with untreated anxiety were at increased risk for NICU admission.

Care of the Fetus With Congenital Cardiovascular Disease: From Diagnosis to Delivery

BACKGROUND

The majority of congenital cardiovascular disease including structural cardiac defects, abnormalities in cardiac function, and rhythm disturbances can be identified prenatally using screening obstetrical ultrasound with referral for fetal echocardiogram when indicated.

METHODS

Diagnosis of congenital heart disease in the fetus should prompt assessment for extracardiac abnormalities and associated genetic abnormalities once maternal consent is obtained. Pediatric cardiologists, in conjunction with maternal-fetal medicine, neonatology, and cardiothoracic surgery subspecialists, should counsel families about the details of the congenital heart defect as well as prenatal and postnatal management.

RESULTS

Prenatal diagnosis often leads to increased maternal depression and anxiety; however, it decreases morbidity and mortality for many congenital heart defects by allowing clinicians the opportunity to optimize prenatal care and plan delivery based on the specific lesion. Changes in prenatal care can include more frequent assessments through the remainder of the pregnancy, maternal medication administration, or, in selected cases, in utero cardiac catheter intervention or surgical procedures to optimize postnatal outcomes. Delivery planning may include changing the location, timing or mode of delivery to ensure that the neonate is delivered in the most appropriate hospital setting with the required level of hospital staff for immediate postnatal stabilization.

CONCLUSIONS

Based on the specific congenital heart defect, prenatal echocardiogram assessment in late gestation can often aid in predicting the severity of postnatal instability and guide the medical or interventional level of care needed for immediate postnatal intervention to optimize the transition to postnatal circulation.

Retinal microvasculature and risk of spontaneous abortion in multiethnic Southeast Asian women

OBJECTIVE

To better understand the underlying pathogenesis of spontaneous abortion that affects 10%-20% of recognized pregnancies. We used retinal imaging to study the role of systemic microvasculature and the risk of spontaneous abortion.

DESIGN

A prospective multiethnic preconception cohort study conducted in Singapore.

SETTING

Hospital-based.

PATIENT(S)

A total of 1,032 Southeast Asian women who intended to conceive naturally were screened at study entry, among which 480 women spontaneously conceived within the 12-month observation period. After excluding 24 women who were lost to follow-up, we calculated the spontaneous abortion rate among 456 women. Further, we included 379 women for the final association analysis because 63 women did not undergo preconception retinal imaging examination and 14 had other types of pregnancy loss instead of spontaneous abortion.

INTERVENTION(S)

Trained photographers performed retinal examination using a 45-degree nonmydriatic retinal camera at study entry during the preconception screening. Using a semiautomated, computer-based program, we assessed quantitative retinal microvascular measurements, including caliber, fractal dimension, curvature tortuosity, and branching angle. Clinical research coordinators collected information on sociodemographic status, menstrual characteristics, and lifestyle, and assessed blood pressure and anthropometry at study entry.

MAIN OUTCOME MEASURE(S)

We performed a modified Poisson regression model to estimate the relative risk (RR) and 95% confidence interval (CI) for each retinal microvascular feature and its association with spontaneous abortion after adjusting for major confounders such as maternal prepregnancy, body mass index, and previous pregnancy loss history.

RESULT(S)

We reported a spontaneous abortion rate of 13.4% (61 out of 456). Among all retinal microvascular features, retinal arteriolar caliber, retinal arteriolar, and venular curvature tortuosity were associated with a high risk of incident spontaneous abortion. In the regression model, per SD increase in retinal curvature tortuosity was associated with a 25%-34% increased risk of incident spontaneous abortion (arteriolar: unadjusted RR, 1.29 [95% CI, 1.06-1.56] and adjusted RR, 1.26 [1.04-1.53]; venule: unadjusted RR, 1.30 [1.08-1.55] and adjusted RR, 1.34 [1.09-1.64]).

CONCLUSION(S)

Our prospective cohort observed an increased risk of spontaneous abortion among Asian women with more tortuous retinal vessels assessed during the preconception phase. Our results indicate a role of vascular inflammatory and oxidative stress in the pathogenesis of spontaneous abortion.

Prenatal maternal stress and offspring aggressive behavior: Intergenerational and transgenerational inheritance

Even though studies have shown that prenatal maternal stress is associated with increased reactivity of the HPA axis, the association between prenatal maternal stress and fetal glucocorticoid exposure is complex and most likely dependent on unidentified and poorly understood variables including nature and timing of prenatal insults. The precise mechanisms in which prenatal maternal stress influence neuroendocrine signaling between the maternal-placental-fetal interface are still unclear. The aim of this review article is to bring comprehensive basic concepts about prenatal maternal stress and mechanisms of transmission of maternal stress to the fetus. This review covers recent studies showing associations between maternal stress and alterations in offspring aggressive behavior, as well as the possible pathways for the “transmission” of maternal stress to the fetus: (1) maternal-fetal HPA axis dysregulation; (2) intrauterine environment disruption due to variations in uterine artery flow; (3) epigenetic modifications of genes implicated in aggressive behavior. Here, we present evidence for the phenomenon of intergenerational and transgenerational transmission, to better understands the mechanism(s) of transmission from parent to offspring. We discuss studies showing associations between maternal stress and alterations in offspring taking note of neuroendocrine, brain architecture and epigenetic changes that may suggest risk for aggressive behavior. We highlight animal and human studies that focus on intergenerational transmission following exposure to stress from a biological mechanistic point of view, and maternal stress-induced epigenetic modifications that have potential to impact on aggressive behavior in later generations.

Effect of video-based information on preoperative State trait anxiety inventory scores in adult patients presenting for elective caesarean section: a randomized controlled trial

Background

Preoperative anxiety is a common occurrence in patients presenting for surgery with a reported incidence of up to 80%. Increased preoperative anxiety has been associated with increased morbidity. Provision of information relating to surgery and anaesthesia to patients has been proven to have benefit in allaying anxiety. However, the best format of information dissemination remains unknown.

Objective

To determine the effect of video information in addition to the pre-anaesthetic review on the mean preoperative State anxiety inventory (STAI-S) score in adult patients presenting for elective caesarean section under spinal anaesthesia at Aga Khan University Hospital, Nairobi (AKUHN), and to determine the prevalence of preoperative anxiety in the obstetric population presenting for elective caesarean section at AKUHN.

Methods

Thirty-seven adult patients booked for elective caesarean section under spinal anesthesia were randomly assigned to one of two groups. In the study arm; a video was shown to the participants in addition to the standard pre-anaesthetic review. In the control arm the participants only had a standard pre-anaesthetic review.

Results

The mean STAI-T score in the sampled population was 45.64 (SD 5.625). The mean baseline STAI-S score was 46.32 (SD 4.911). There was no statistically significant difference in change in STAI score between the video and control arms (p>0.05).

Conclusion

On the basis of this study among this population, there was no benefit demonstrated from the use of an information video about spinal anaesthesia on anxiety levels in obstetric patients presenting for a first time spinal.

Pregnant women's experience of undergoing an oral glucose tolerance test: A cross-sectional study

AIMS

The oral glucose tolerance test (OGTT) is routinely performed in most pregnancies; however, there are few studies which document the experience of taking this test. We assessed the experience of pregnant women during an OGTT.

METHODS

This cross-sectional study included 152 women (24-32 weeks' gestation) and assessed their knowledge, anxiety (Spielberg anxiety inventory test-STAI), and physical pain (0-10 visual analog scale) during the OGTT. The Friedman test was used to compare pain scores over time.

RESULTS

61 (40%) participants did not know why they were doing the OGTT and 73 (48%) women had high state-anxiety levels (STAI ≥ 41 points, 20-80 scale). Participants had mild to moderate pain scores immediately after the first and second blood draws (3.9 ± 2.7 and 3.8 ± 2.3, respectively) that decreased significantly after the third blood draw (2.8 ± 2.4, P < 0.001). Nearly half (n = 71, 47%) of the participants were very or extremely bothered with having to drink the glucose solution.

CONCLUSIONS

The OGTT was associated with high levels of anxiety and mild to moderate physical pain. Ingestion of the glucose solution was perceived as the most difficult part of the test. Good strategies can help to mitigate some of these negative experiences while undergoing an OGTT.

In Utero MRI Identifies Impaired Second Trimester Subplate Growth in Fetuses with Congenital Heart Disease

The subplate is a transient brain structure which plays a key role in the maturation of the cerebral cortex. Altered brain growth and cortical development have been suggested in fetuses with complex congenital heart disease (CHD) in the third trimester. However, at an earlier gestation, the putative role of the subplate in altered brain development in CHD fetuses is poorly understood. This study aims to examine subplate growth (i.e., volume and thickness) and its relationship to cortical sulcal development in CHD fetuses compared with healthy fetuses by using 3D reconstructed fetal magnetic resonance imaging. We studied 260 fetuses, including 100 CHD fetuses (22.3-32 gestational weeks) and 160 healthy fetuses (19.6-31.9 gestational weeks). Compared with healthy fetuses, CHD fetuses had 1) decreased global and regional subplate volumes and 2) decreased subplate thickness in the right hemisphere overall, in frontal and temporal lobes, and insula. Compared with fetuses with two-ventricle CHD, those with single-ventricle CHD had reduced subplate volume and thickness in right occipital and temporal lobes. Finally, impaired subplate growth was associated with disturbances in cortical sulcal development in CHD fetuses. These findings suggested a potential mechanistic pathway and early biomarker for the third-trimester failure of brain development in fetuses with complex CHD.

SIGNIFICANCE STATEMENT

Our findings provide an early biomarker for brain maturational failure in fetuses with congenital heart disease, which may guide the development of future prenatal interventions aimed at reducing neurological compromise of prenatal origin in this high-risk population.

Incidence of Postpartum Depression and Its Association With Antenatal Psychiatric Symptoms: A Longitudinal Study in 25 Villages of Rural South Karnataka

BACKGROUND

Postpartum depression (PPD) is the commonest mental health disorder post-childbirth, yet there is a paucity of data in rural areas regarding the actual incidence of PPD, which excludes pre-existing or antenatal depression. To estimate the incidence of PPD among rural women of south Karnataka and identify predictors of PPD, including antenatal psychiatric disorders.

METHODS

A longitudinal study in 25 villages in south Karnataka among 150 pregnant women in the third trimester of pregnancy using simple random sampling. Baseline data collected and revised Clinical Interview Schedule used to screen antenatal psychiatric disorders. Participants followed-up 6-8 weeks postpartum, end-line data collected, and Edinburg Postnatal Depression Scale administered. Chi-square and Fischer's exact tests for association between PPD and covariates. Logistic regression to calculate adjusted odds ratios.

RESULTS

Prevalence of antenatal psychiatric disorders was 15.3%. The incidence of PPD was 11%. A significantly higher proportion of PPD was found among women with adverse events in the last year, low socioeconomic status, and perceived lack of care/support at home. Predictors of PPD were antenatal psychiatric disorders (AOR = 4.3, 95% CI = 1.22-5.11; P = 0.028), mothers reporting worry about their infant's health (AOR = 7.7, 95% CI = 1.22-48.32; P = 0.012) and mothers receiving postpartum care by caregivers other than their own mother (AOR = 4.0, 95% CI = 1.13-8.09; P = 0.030).

CONCLUSIONS

Our study found that one in ten rural women is developing PPD and there is a strong link between PPD and antenatal psychiatric disorders and family factors. This calls for capacity building of general physicians and village-level workers and strengthening of the Home-Based Newborn Care Program, where weekly postpartum home visits by ASHA are an opportunity for screening and counselling mothers.

Retinal microvasculature and time to pregnancy in a multi-ethnic pre-conception cohort in Singapore

STUDY QUESTION

Can abnormalities in retinal microvasculature representing adverse microcirculatory perfusion and inflammation shed light on the pathophysiology of female fecundability?

SUMMARY ANSWER

In our prospective study, abnormalities in retinal vascular geometric morphology (i.e. sparser arteriolar fractal and larger venular bifurcation) during pre-conception phase are temporarily associated with a prolonged time-to-pregnancy (TTP).

WHAT IS KNOWN ALREADY

Suboptimal retinal microcirculatory morphology has been associated with obesity, psychological stress and hypertension, all of which are known risk factors for reduced female fecundability.

STUDY DESIGN, SIZE, DURATION

A total of 652 women of Chinese, Malay or Indian ethnicity 18-45 years of age and planning to conceive spontaneously within the next 12 months were recruited during the pre-conception period into the Singapore PREconception Study of long-Term maternal and child Outcomes (S-PRESTO), from February 2015 to October 2017.

PARTICIPANTS/MATERIALS, SETTING, METHODS

During recruitment, we collected information on socio-demographic factors, menstrual characteristics and lifestyle behaviors and made anthropometric measurements. We assessed the following retinal microvascular features: caliber, branching angle and fractal dimension. We conducted follow-up telephone surveys to track each participant's pregnancy status at 6, 9 and 12 months after enrolment. We ascertained clinical pregnancies via ultrasonography, with TTP measured by the number of menstrual cycles required to achieve a clinical pregnancy over a 1-year follow-up. Then, we performed discrete-time proportional hazards models to estimate the fecundability odds ratio (FOR) and 95% CI for each retinal microvascular feature in association with TTP, after adjusting for major confounders, including body mass index and fasting glycemic level at study entry.

MAIN RESULTS AND THE ROLE OF THE CHANCE

Among 652 recruited women, 276 (42.3%) successfully conceived within 1 year of follow-up. The mean (and SD) was 1.24 (0.05) Df for retinal arteriolar dimension fraction and 78.45 (9.79) degrees for retinal venular branching angle, respectively. Non-linear relationship testing was performed before multiple adjustment in all associations and a non-monotonic association was detected between retinal venular branching angle and TTP. Compared with women in the highest tertile of retinal arteriolar fractal dimension, women in the second tertile had a prolonged TTP (FOR: 0.68; 95% CI: 0.51-0.92), as did women in the lowest tertile (FOR: 0.73; 95% CI: 0.55-0.98). Compared with women in the middle tertile of retinal venular branching angle, women in the highest tertile had a borderline prolonged TTP (FOR: 0.75; 95% CI: 0.56-1.02). No other retinal vascular features were significantly associated with TTP.

LIMITATIONS, REASONS FOR CAUTION

We were unable to adjust for other potential confounding factors such as female sexual function (e.g. frequency of sexual intercourse), which might introduce a residual bias. Moreover, even though this is a prospective cohort design, our findings can identify the temporal relationship but not necessarily infer a causal relationship between maternal microvasculature and TTP. Lastly, our study involving mainly Chinese, Malay and Indian ethnicities might not be generalizable to other races or ethnicities.

WIDER IMPLICATIONS OF THE FINDINGS

Suboptimal microcirculation may lead to reduced female fecundability. In the future, in addition to conventional ultrasonographic evaluation of ovarian and uterine physiological function, assessing the retinal microvasculature might be useful for assessment of ovarian age, fertility prediction and endometrial evaluation before assisted reproductive techniques for fertility treatments.

Association between fetoplacental Doppler results, placental pathology, and angiogenic factors among pregnant women with anxiety

OBJECTIVE

This study aimed to evaluate whether state and trait anxiety among pregnant women were associated with fetoplacental Doppler findings, abnormal placental pathology, and placental angiogenic factors.

MATERIALS AND METHODS

A total of 102 pregnant women at 32-35 gestational weeks were recruited and examined prospectively. State and trait anxiety were measured using the State-Trait Anxiety Inventory. Using Doppler ultrasound, pulsatility index (PI) of the umbilical artery (UA), middle cerebral artery (MCA), and uterine artery (UtA) and cerebroplacental ratio (CPR) were determined. Doppler parameters were converted into multiples of the median (MoM). Abnormal placental pathology was classified into 2 groups: vascular underperfusion (VU) and histological chorioamnionitis (HCA). Immunohistochemical analysis was performed to examine placental cells staining positive for placental growth factor (PLGF) and hypoxia-inducible factor-1-α (HIF-1α), which are markers for angiogenesis and hypoxic status, respectively.

RESULTS

Women with high state anxiety scores had low MCA-PI MoM and CPR MoM, while those with high trait anxiety scores had low MCA-PI MoM. VU was associated with a higher incidence of high trait anxiety scores, and HCA was associated with a higher incidence of high state and trait anxiety scores. Regression analysis showed a relationship between maternal state anxiety on MCA-PI MoM and HCA after controlling for covariates. Maternal trait anxiety exhibited relationships with VU and HCA after adjustment.

CONCLUSION

Our results demonstrated that maternal anxiety is associated with altered fetal cerebral blood flow and abnormal placental pathology but is not associated with uteroplacental insufficiency and placental angiogenic factors.

Adverse Pregnancy Outcomes Following the Assassination of John F. Kennedy in 1963

INTRODUCTION

Women exposed to stressful events during pregnancy are thought to be at increased risk of adverse birth outcomes. However, studies investigating stressful events are often unable to control for important confounders, such as behavioral and genetic characteristics, or to isolate the impact of the stressor from other secondary effects. We used a discordant-sibling design, which provides stronger inferences about causality, to examine whether a widespread stressor with limited impact on day-to-day life (John F. Kennedy assassination) resulted in an increased risk of adverse birth outcomes.

METHODS

Data were obtained from the Collaborative Perinatal Project, a prospective, multi-site cohort study conducted in the US from 1959 to 1965. Our analysis was restricted to singleton live births ≥24 weeks born before the assassination (n = 24,406) or in utero at the time (n = 5833). We also evaluated associations within siblings discordant for exposure (n = 1144). We used survival analysis to evaluate associations between exposure and preterm birth and marginal models to evaluate associations with birthweight and placental pathology.

RESULTS

First trimester exposure was associated with preterm birth (hazard ratio (HR): 1.17; 95% CI: 1.05, 1.31). In the discordant-sibling model, the point estimate was similar (HR: 1.22; 95% CI: 0.36, 4.06). Third trimester exposure was associated with increased odds of fetal acute inflammation in the placenta (odds ratio (OR): 1.34, 95% CI: 1.05, 1.71).

CONCLUSIONS FOR PRACTICE

First trimester exposure to an acute stressor was associated with preterm birth. We did not observe increased odds of placental pathology with first trimester exposure; however, stress may increase preterm birth risk through chronic placental inflammation, which was not evaluated in this sample.

Uterine blood flow, fetal heart rate, gestational length, and fetal birth weight variability in response to maternal temperament in the goat

This prospective study was designed to investigate the effects of maternal temperament on uterine blood flow, fetal heart rate, gestational length, and fetal birth weight in a goat experimental model. Based on the arena test, behavioral testing related to fear-eliciting stimulus, goats were divided into nervous (n = 13) and calm (n = 11) groups. After mating, the perfusion of maternal uterine arteries (UTAs) and its related Doppler parameters, blood flow volume (BFV), time-averaged mean velocity (TAMEANV), acceleration (Acce), and resistance impedance (S/D), were evaluated biweekly from week two until the end of pregnancy. Fetal heart rate (FHR) was investigated during the pregnancy in addition to the gestation length (GL) and fetal birth weight (FBW). The UTA-BFV and TAMEANV, as well as Acce and S/D, were influenced by maternal temperament (p < .05). The FHR showed no significant changes between experimental animals of different temperaments (p = .81). Both GL and FBW were increased in calm rather than nervous goats (p < .05). These results indicated that the maternal nervous (temperament) have negative impacts on uterine artery Doppler indices, fetal growth, and gestational length in a goat experimental model.

[Effects of First Assisted Reproductive Technologies on Anxiety and Depression among Infertile Women: A Systematic Review and Meta-Analysis]

PURPOSE

The purpose of this study was to analyze anxiety and depression among infertile women at different time points during the first In Vitro Fertilization (IVF) or Intracytoplasmic Sperm Injection (ICSI) treatment through a systematic review and meta-analysis.

METHODS

Seven out of 3,011 studies were included for meta-analysis. To estimate the effect size, a meta-analysis of the studies was performed using the RevMan 5.3 program. We compared the measurement outcomes at three time points: before the start of treatment (T0), cancellation of treatment after pregnancy detection (T2), one to six months after treatment (T3). The effect size used was the standardized mean difference (SMD).

RESULTS

In comparing the different time points of the pregnant women from their cycle, significantly lower levels of depression were found at T2 than at T0. In non-pregnant women, anxiety at T2 and depression at T2 and T3 were significantly higher than those at T0. At T2 and T3, the non-pregnant women reported higher levels of anxiety and depression compared with the pregnant women.

CONCLUSION

Anxiety and depression in infertile women undergoing the first IVF or ICSI are associated with the time points and pregnancy status after treatment. These findings suggest that attention should be paid to helping infertile women prepare for and cope with treatment and treatment failure.

Maternal experience of domestic violence before and during pregnancy and children's linear growth at 15 years: Findings from MINIMat trial in rural Bangladesh

Literature concerning negative impacts of domestic violence (DV) against women on their children's health is growing; however, little is known about the long‐term effect of maternal exposure to DV before and/or during pregnancy on their children's growth. Using data from the MINIMat cohort, we have evaluated the association between maternal lifetime experience of DV, measured in late pregnancy, with their children's linear growth at 15 years (n = 2240) in rural Bangladesh. A modified version of conflict tactic scale was used to record the maternal experience of physical, sexual, emotional DV and controlling behaviour. Children's height was measured by trained nurses during their clinical visits at 15‐year follow‐up. Compared to the women with no experience of DV, children of women with experience of any physical, sexual or emotional DV before and/or during pregnancy had the significantly lower height for age Z‐scores (HAZs) at the age of 15. No significant association between maternal experience of controlling behaviour and their children's linear growth was observed in terms of HAZ. Results from this study suggest that maternal experience of DV before and/or during pregnancy might be associated with impaired long‐term linear growth within their children.

Effects of Mind-Body Programs on Infertile Women: A Systematic Review and Meta-analysis of Randomized Controlled Trials

PURPOSE

This study was to systematically review randomized controlled trials and conduct a meta analysis. The results of randomized controlled trials were integrated and analyzed to assess the effects of mind-body programs on anxiety, depression, quality of life, and pregnancy rate in infertile women.

METHODS

Using electronic databases (i.e., Research Information Sharing Service, Korean Studies Information Service System, Korean Medical Database, National Digital Science Library, Cochrane Library, PubMed, EMBASE, Cumulative Index to Nursing and Allied Health Literature, and PsycARTICLES), 10 of 2,259 studies were included for meta-analysis. To estimate the effect size, a meta-analysis of the studies was performed using RevMan 5.3.

RESULTS

The mind-body program was effective in relieving anxiety [standardized mean difference (SMD) = -3.44; 95% confidence interval (CI) = -5.94, -0.95; p = .007; I² = 69%] and depression (SMD = -5.79; 95% CI = -10.36, -1.22; p = .010; I² = 86%). Furthermore, it was effective in enhancing the quality of life (SMD = 7.40; 95% CI = 2.92, 11.88; p = .001; I² = 53%) and pregnancy rate (SMD = 2.06; 95% CI = 1.08, 3.95; p = .030; I² = 73%). The mind-body program was found to relieve anxiety and depression in infertile women and improve their quality of life, thereby positively affecting the pregnancy rate.

CONCLUSION

The mind-body program was found to relieve anxiety and depression in infertile women and improve their quality of life, thereby positively affecting the pregnancy rate. The mind-body program needs to be considered to a wider audience for positive effects on emotions and pregnancy outcomes of infertile women.

Heightened immigration enforcement impacts US citizens' birth outcomes: Evidence from early ICE interventions in North Carolina

We examine how increased Immigration and Customs Enforcement (ICE) activities impacted newborn health and prenatal care utilization in North Carolina around the time Section 287(g) of the Immigration and Nationality Act was first being implemented within the state. Focusing on administrative data between 2004 and 2006, we conduct difference-in-differences and triple-difference case-control regression analysis. Pregnancies were classified by levels of potential exposure to immigration enforcement depending on parental nativity and educational attainment. Contrast groups were foreign-born parents residing in nonadopting counties and all US-born non-Hispanic parents. The introduction of the program was estimated to decrease birth weight by 58.54 grams (95% confidence interval [CI], -83.52 to -33.54) with effects likely following from reduced intrauterine growth. These results are shown to coexist with a worsening in the timing of initiation and frequency of prenatal care received. Since birth outcomes influence health, education, and earnings trajectories, our findings suggest that the uptick in ICE activities can have large socioeconomic costs over US-born citizens.

Associations of Partnership Quality and Father-to-Child Attachment During the Peripartum Period. A Prospective-Longitudinal Study in Expectant Fathers

Background: During the transition to parenthood, a complex network of relationships unfolds between father, mother and the child. Expectant parents begin bonding with their unborn child, with this antenatal process supposedly being predictive for later postnatal attachment and child mental health. At the same time, couples may experience a change in partnership quality. While the majority of previous studies focused on associations between psychopathology, partnership quality and attachment from the perspective of mothers, the changes in partnership quality and attachment from the perspective of fathers has gained far less attention. Methods: Data were derived from the Maternal Anxiety and it's Relation to Infants' Development (MARI) study. N = 109 expectant fathers were recruited during mid-pregnancy (22 to 26 week of gestation). Lifetime anxiety and depressive disorders (DSM-IV) were assessed with a standardized diagnostic interview (CIDI). Paternal partnership characteristics and father-to-child attachments were assessed using standardized questionnaires at the second trimester, 10 days after delivery and 4 months after delivery in N = 76 fathers. Analyses were based on bivariate, robust and multivariate regression analyses. Results: Fathers did not report an overall decrease in partnership quality during the peripartum period. However, fathers with comorbid anxiety and depressive disorders reported lower partnership satisfaction at postpartum, as compared to unaffected fathers. Fathers with pure depressive disorders reported lower intensity of antenatal attachment. Paternal antenatal partnership quality was positively associated with antenatal father-to-child attachment. Furthermore, antenatal father-to-child attachment, as well as ante- and postnatal partnership quality in fathers, were positively related to postnatal father-to-child attachment. Conclusions: Antenatal father-to-child-attachment and paternal partnership quality appear to be promising targets for the prevention of postnatal attachment problems in fathers. The associations between partnership quality and attachment to the child further support an interpersonal approach in perinatal research, treatment and intervention, and may also feed into awareness programs that encourage expectant fathers to actively engage in relationships as early as during pregnancy-both with the mother and the unborn child.

Executive functioning in 6 year old children exposed to chemotherapy in utero

BACKGROUND

Cancer treatment during pregnancy imposes a dilemma. Maternal advantage should be weighed against the potential impact of chemotherapy on child development. Recent studies in cancer survivors have shown that exposure to chemotherapeutic agents can have late adverse effects on cognitive functioning and executive functioning (EF). It is still unclear whether these late adverse effects also arise if a child is exposed to chemotherapy in utero.

AIM

To compare the development of executive functioning in 6 year old children prenatally exposed to chemotherapy (study group) and children born to healthy women after an uncomplicated pregnancy (control group).

METHODS AND STUDY DESIGN

In a multicenter cohort study, the outcome on a measure of EF was compared. Study and control children were prospectively examined by means of the Behavior Rating Inventory of Executive Function (BRIEF), a health questionnaire and an intelligence test.

RESULTS

In total 37 study children and 37 matched controls were included. In the study group, 11 children (29.7%) were exposed to chemotherapy alone, 22 children (59.5%) were exposed to chemotherapy and surgery and 4 children (10.8%) were exposed to chemotherapy, surgery and radiotherapy during pregnancy. All outcome scales of the BRIEF were within normal ranges. However, a significant between-group difference in emotional control was found.

CONCLUSION

Overall outcomes of EF were reassuring. However, children prenatally exposed to chemotherapy have weaker emotion regulation skills compared to their matched controls. The results underscore the need for long-term follow-up of these children.

Association Between Maternal Perinatal Depression and Anxiety and Child and Adolescent Development: A Meta-analysis

IMPORTANCE

There is widespread interest in associations between maternal perinatal depression and anxiety and offspring development; however, to date, there has been no systematic, meta-analytic review on the long-term developmental outcomes spanning infancy through adolescence.

OBJECTIVE

To provide a comprehensive systematic review and meta-analysis of the extant literature on associations between maternal perinatal depression and anxiety and social-emotional, cognitive, language, motor, and adaptability outcomes in offspring during the first 18 years of life.

DATA SOURCES

Six databases were searched (CINAHL Complete, Cochrane Library, Embase, Informit, MEDLINE Complete, and PsycInfo) for all extant studies reporting associations between perinatal maternal mental health problems and offspring development to March 1, 2020.

STUDY SELECTION

Studies were included if they were published in English; had a human sample, quantitative data, a longitudinal design, and measures of perinatal depression and/or anxiety and social-emotional, cognitive, language, motor, and/or adaptability development in offspring; and investigated an association between perinatal depression or anxiety and childhood development.

DATA EXTRACTION AND SYNTHESIS

Of 27 212 articles identified, 191 were eligible for meta-analysis. Data were extracted by multiple independent observers and pooled using a fixed- or a random-effects model. A series of meta-regressions were also conducted. Data were analyzed from January 1, 2019, to March 15, 2020.

MAIN OUTCOMES AND MEASURES

Primary outcomes included social-emotional, cognitive, language, motor, and adaptability development in offspring during the first 18 years of life.

RESULTS

After screening, 191 unique studies were eligible for meta-analysis, with a combined sample of 195 751 unique mother-child dyads. Maternal perinatal depression and anxiety were associated with poorer offspring social-emotional (antenatal period, r = 0.21 [95% CI, 0.16-0.27]; postnatal period, r = 0.24 [95% CI, 0.19-0.28]), cognitive (antenatal period, r = -0.12 [95% CI, -0.19 to -0.05]; postnatal period, r = -0.25 [95% CI, -0.39 to -0.09]), language (antenatal period, r = -0.11 [95% CI, -0.20 to 0.02]; postnatal period, r = -0.22 [95% CI, -0.40 to 0.03]), motor (antenatal period, r = -0.07 [95% CI, -0.18 to 0.03]; postnatal period, r = -0.07 [95% CI, -0.16 to 0.03]), and adaptive behavior (antenatal period, r = -0.26 [95% CI, -0.39 to -0.12]) development. Findings extended beyond infancy, into childhood and adolescence. Meta-regressions confirmed the robustness of the results.

CONCLUSIONS AND RELEVANCE

Evidence suggests that perinatal depression and anxiety in mothers are adversely associated with offspring development and therefore are important targets for prevention and early intervention to support mothers transitioning into parenthood and the health and well-being of next-generation offspring.

Relationships between mental health and diet during pregnancy and birth outcomes in a lower-middle income country: "Healthy mothers, healthy communities" study in Vanuatu

Poor maternal mental health during pregnancy is associated with adverse birth outcomes, including lower birthweight and gestational age. However, few studies assess both mental health and diet, which might have interactive effects. Furthermore, most studies are in high-income countries, though patterns might differ in low- and middle-income countries (LMICs).

OBJECTIVES

To analyze relationships between mental health and diet during pregnancy with birth outcomes in Vanuatu, a lower-middle income country.

METHODS

We assessed negative emotional symptoms of depression, anxiety, and stress (referred to as "distress") and dietary diversity during pregnancy, and infant weight and gestational age at birth, among 187 women. We used multivariate linear regression to analyze independent and interactive relationships between distress, dietary diversity, and birth outcomes, controlling for sociodemographic and maternal health covariates.

RESULTS

There were no direct linear relationships between dietary diversity or distress with infant birthweight or gestational age, and no curvilinear relationships between distress and infant outcomes. We observed interactive relationships between distress and dietary diversity on birthweight, explaining 2.1% of unique variance (P = .024). High levels of distress predicted lower birthweights among women with low dietary diversity. These relationships were not evident among women with moderate or high dietary diversity.

CONCLUSIONS

Relationships between mental health and diet might underlie inconsistencies in past studies of prenatal mental health and birthweight. Results highlight the importance of maternal mental health on birthweight in LMICs. Interactive relationships between mental health and diet might ultimately point to new intervention pathways to address the persistent problem of low birthweight in LMICs.

The Effect of Antepartum Depression on the Outcomes of Pregnancy and Development of Postpartum Depression: A prospective cohort study of Omani women

Objectives

This study aimed to identify the relationship between antenatal depression and pregnancy outcomes, including the risk of developing postpartum depression in Oman.

Methods

This follow-up prospective longitudinal cohort study included pregnant women attending primary healthcare institutions in Muscat, Oman from January to November 2014. The Edinburgh Postnatal Depression Scale (EPDS) was used to screen for antenatal and postnatal depression. Pregnant Omani women with a gestational age ≥32 weeks attending 12 local health centres for antenatal care in Muscat were invited to participate. Recruited women were followed-up at 6–8 weeks after delivery. The following pregnancy outcomes were assessed: mode of delivery (normal or Caesarean section [CS]), gestational age at delivery (preterm or full-term), baby’s birth weight and development of postnatal depression.

Results

A total of 959 women participated in this study (response rate: 97.3%). In total, 233 women (24.4%) had antenatal depression with a score of ≥13 on the EPDS. Of the 592 participants (61.7%) who attended postnatal clinics at 6–8 weeks post-delivery, 126 (21.3%) were positive for postnatal depression. Logistic multivariate regression analysis showed that antenatal depression was associated with increased risk of CS (odds ratio [OR] = 1.79; 95% confidence interval [CI]: 1.20–2.66) and postnatal depression (OR = 8.63; 95% CI: 5.56–13.39).

Conclusion

Screening women for antenatal depression and providing appropriate management may reduce adverse pregnancy outcomes and the risk of developing postnatal depression.

Effects of an Informational Video About Anesthesia on Pre- and Post-Elective Cesarean Section Anxiety and Recovery: A Randomized Controlled Trial

Background

Showing an informational anesthesia video can reduce the preoperative anxiety of parturients undergoing elective cesarean section (CS). However, the best method for presenting such videos remains unclear, and whether such videos can reduce the anxiety level of women during the entire perioperative period for CS (including preoperative and postoperative) has not been studied yet.

Material/Methods

This study was a single-center prospective randomized trial. We randomly divided 121 pregnant women who were scheduled to undergo elective cesarean section (CS) into 2 groups: one group was shown an informational video (video group) and another group was not (control group). Spielberger’s state-trait anxiety inventory was used to evaluate the perioperative anxiety level of parturient women at 3 time points: 1 day before CS, after video education, and 2 days after CS. Salivary cortisol level was evaluated to assess the patients’ anxiety level at these 3 time points. Finally, the maternal satisfaction scale for CS and an obstetric quality-of-recovery score (OBsQoR-11) were used to evaluate the satisfaction and recovery of the parturient women 2 days after CS.

Results

Watching a video about anesthesia significantly reduced the anxiety level of the parturient women during the perioperative period (1 day before CS: p=1.00, p=0.96; after video education: p<0.01, p=0.004; 2 days after CS: p=0.01, p=0.01). The postoperative satisfaction scores were significantly improved in the video group (p=0.007). OBsQoR-11 scores in the video group and control group were not significantly different (p=0.48). Maternal anxiety level was moderately positively correlated with cortisol hormone level.

Conclusions

Showing an informational video about anesthesia (video+education) can significantly reduce perioperative anxiety and improve satisfaction after CS. Although it did not improve the postoperative recovery, it was still significant for anesthesia.

Maternal chronic stress correlates with serum levels of cortisol, glucose and C-peptide in the fetus, and maternal non chronic stress with fetal growth

INTRODUCTION

During pregnancy, maternal stressors cause changes in both maternal and fetal HPA axes. We therefore investigated the impact of maternal non chronic and chronic stress on fetal glucose metabolism and growth, and serum levels of cortisol in the fetus.

MATERIALS AND METHODS

Normal weight pregnant women (n = 192; mean ± SD 27.9 ± 4.2 years old, and; 26.9 ± 2.4 kg/m²) were assessed during the 2nd and 3rd trimester with anthropometry, fetal ultrasound, blood samples for serum CRH, cortisol and IL6, and STAI trait and state stress questionnaires. We measured serum cortisol, insulin and c-peptide, and plasma glucose from cord blood. Neonates underwent anthropometry at the 3rd post-delivery day.

RESULTS

In both 2nd and 3rd trimesters, women with STAI trait scores ≥40 had significantly greater levels of fasting serum CRH and cortisol than those with STAI trait scores<40. 2nd trimester: STAI trait scores correlated positively with cord blood glucose and c-peptide. Maternal serum CRH correlated negatively with U/S fetal biparietal head diameter, while serum cortisol correlated positively with abdominal circumference. Maternal serum IL6, CRH and cortisol all correlated positively with birth waist circumference. 3rd trimester: Women with STAI state scores ≥40 had fetuses with larger U/S abdominal and smaller head circumferences compared to those of women with STAI scores <40. Women with STAI trait scores ≥40 had greater levels of cord blood cortisol, glucose, and c-peptide compared to women with STAI scores <40. STAI state scores ≥40 correlated positively with maternal CRH and U/S fetal abdominal circumference, and negatively with fetal head circumference and biparietal diameter. STAI trait scores correlated positively with cord blood c-peptide, glucose, insulin and cortisol. Maternal serum levels of CRH correlated positively with U/S fetal abdominal circumference and cord blood cortisol, and negatively with fetal head circumference and biparietal head diameter. Maternal serum levels of both CRH and cortisol correlated positively with cord blood c-peptide, glucose, and insulin. STAI trait was the best positive predictor of cord blood cortisol, glucose and c-peptide, whilst STAI state was the best positive and negative predictor, respectively of fetal abdominal circumference and fetal head circumference or biparietal diameter.

CONCLUSIONS

Increased maternal chronic stress (reflected by the STAI trait score) associates with increased fetal cortisol, glucose, c-peptide secretion and thus, insulin resistance. Maternal non chronic stress (STAI state) in the 3rd trimester associates with changes in fetal growth pattern, including increased and decreased measurements of fetal abdominal and head growth respectively.

The course of panic disorder during the peripartum period and the risk for adverse child development: A prospective-longitudinal study

BACKGROUND

Panic disorders during pregnancy and after delivery may have detrimental effects for mother and child, but no firm conclusions regarding the course and outcomes of peripartum panic disorders can be drawn from previous studies.

METHODS

N = 306 women were repeatedly interviewed with the Composite International Diagnostic Interview for Women. Social support and partnership quality, gestational outcomes, duration of breastfeeding, regulatory disorders, maternal bonding and parenting style were assessed via medical and maternal reports. Standardized observations of neuropsychological development, infant temperament and attachment were conducted 4 and 16 months after delivery.

RESULTS

Women reported heterogenous courses of panic disorders, and panic disorders/panic attacks were commonly observed during the early stages of pregnancy. Women with peripartum panic disorders presented with a worse psychosocial situation (e.g., lower social support). Clear behavioral differences (temperament, attachment) in infants of women with panic disorders as compared to women with no anxiety and depressive disorder could not be detected in this study, but differences concerning gestational outcomes, duration of breastfeeding, maternal parenting, and bonding as well as regulatory problems in infants were identified.

LIMITATIONS

This prospective-longitudinal multi-wave study is restricted by the relative small sizes of the particular groups that limit the power to detect group differences.

CONCLUSIONS

Heterogenous courses and outcomes of perinatal panic disorders require intensive monitoring of affected mother-infant-dyads who may benefit from early targeted interventions to prevent an escalation of dyadic problems.

Association of Maternal Psychological Distress With In Utero Brain Development in Fetuses With Congenital Heart Disease

IMPORTANCE

Prenatal maternal psychological distress can result in detrimental mother and child outcomes. Maternal stress increases with receipt of a prenatal diagnosis of fetal congenital heart disease (CHD); however, the association between maternal stress and the developing brain in fetuses with CHD is unknown.

OBJECTIVE

To determine the association of maternal psychological distress with brain development in fetuses with CHD.

DESIGN, SETTING, AND PARTICIPANTS

This longitudinal, prospective, case-control study consecutively recruited 48 pregnant women carrying fetuses with CHD and 92 healthy volunteers with low-risk pregnancies from the Children's National Health System between January 2016 and September 2018. Data were analyzed between January 2016 and June 2019.

EXPOSURES

Fetal CHD and maternal stress, anxiety, and depression.

MAIN OUTCOMES AND MEASURES

Maternal stress, anxiety, and depression were measured using the Perceived Stress Scale, Spielberger State-Trait Anxiety Inventory, and Edinburgh Postnatal Depression Scale, respectively. Volumes of fetal total brain, cerebrum, left and right hippocampus, cerebellum, and brainstem were determined from 3-dimensionally reconstructed T2-weighted magnetic resonance imaging (MRI) scans.

RESULTS

This study included 223 MRI scans from 140 fetuses (74 MRIs from 48 fetuses with CHD and 149 MRIs from 92 healthy fetuses) between 21 and 40 weeks' gestation. Among 48 women carrying fetuses with CHD, 31 (65%) tested positive for stress, 21 (44%) for anxiety, and 14 (29%) for depression. Among 92 pregnant women carrying healthy fetuses, 25 (27%) tested positive for stress, 24 (26%) for anxiety, and 8 (9%) for depression. Depression scores were higher among 17 women carrying fetuses with single-ventricle CHD vs 31 women carrying fetuses with 2-ventricle CHD (3.8; 95% CI, 0.3 to 7.3). Maternal stress and anxiety were associated with smaller left hippocampal (stress: -0.003 cm3; 95% CI, -0.005 to -0.001 cm3), right hippocampal (stress: -0.004; 95% CI, -0.007 to -0.002; trait anxiety: -0.003; 95% CI, -0.005 to -0.001), and cerebellar (stress: -0.06; 95% CI, -0.09 to -0.02) volumes only among women with fetal CHD. Impaired hippocampal regions were noted in the medial aspect of left hippocampal head and inferior aspect of right hippocampal head and body. Impaired cerebellar regions were noted in the anterior superior aspect of vermal and paravermal regions and the left cerebellar lobe.

CONCLUSIONS AND RELEVANCE

These findings suggested that psychological distress among women carrying fetuses with CHD is prevalent and is associated with impaired fetal cerebellar and hippocampal development. These data underscore the importance of universal screening for maternal psychological distress, integrated prenatal mental health support, and targeted early cognitive-behavioral interventions given that stress is a potentially modifiable risk factor in this high-risk population.

Cognitive Behavioral Therapy for Antenatal Depression in a Pilot Randomized Controlled Trial and Effects on Neurobiological, Behavioral and Cognitive Outcomes in Offspring 3-7 Years Postpartum: A Perspective Article on Study Findings, Limitations and Future Aims

PURPOSE OF ARTICLE

In a previous pilot randomized controlled trial including 54 pregnant women with depression, maternal mood improved after Cognitive Behavioural Therapy (CBT) compared to treatment as usual (TAU), showing medium to large effect sizes. The effect persisted up to 9 months postpartum, with infant outcomes also showing medium to large effects favoring CBT in various child domains. This perspective article summarizes the results of a follow-up that was performed approximately 5 years later in the same cohort, assessing the effects of antenatal Cognitive Behavioural Therapy for depression and anxiety on child buccal cell DNA-methylation, brain morphology, behavior and cognition.

FINDINGS

Children from the CBT group had overall lower DNA-methylation compared to children from the TAU group. Mean DNA-methylation of all NR3C1 promoter-associated probes did not differ significantly between the CBT and TAU groups. Children from the CBT group had a thicker right lateral occipital cortex and lingual gyrus. In the CBT group, Voxel-Based-Morphometry analysis identified one cluster showing increased gray matter concentration in the right medial temporal lobe, and fixel-based analysis revealed reduced fiber-bundle-cross-section in the Fornix, the Optical Tract, and the Stria Terminalis. No differences were observed in full-scale IQ or Total Problems Score. When the total of hypotheses tests in this study was considered, differences in DNA-methylation and brain measurements were no longer significant.

SUMMARY

Our explorative findings suggest that antenatal depression treatment decreases overall child DNA-methylation, increases cortical thickness, and decreases white matter fiber-bundle cross-section in regions involved in cognitive function and the stress response. Nevertheless, larger studies are warranted to confirm our preliminary conclusion that CBT in pregnancy alters neurobiological outcomes in children. Clinical relevance remains unclear as we found no effects of antenatal CBT on child behavior or cognition (yet).

Association of Prenatal Maternal Psychological Distress With Fetal Brain Growth, Metabolism, and Cortical Maturation

IMPORTANCE

Prenatal maternal stress is increasingly associated with adverse outcomes in pregnant women and their offspring. However, the association between maternal stress and human fetal brain growth and metabolism is unknown.

OBJECTIVE

To identify the association between prenatal maternal psychological distress and fetal brain growth, cortical maturation, and biochemical development using advanced 3-dimensional volumetric magnetic resonance imaging (MRI) and proton magnetic resonance spectroscopy (1H-MRS).

DESIGN, SETTING, AND PARTICIPANTS

This cohort study prospectively recruited pregnant women from low-risk obstetric clinics in Washington, DC, from January 1, 2016, to April 17, 2019. Participants were healthy volunteers with a normal prenatal medical history, no chronic or pregnancy-induced physical or mental illnesses, and normal results on fetal ultrasonography and biometry studies. Fetal brain MRI studies were performed at 2 time points between 24 and 40 weeks' gestation.

EXPOSURES

Prenatal maternal stress, anxiety, and depression.

MAIN OUTCOMES AND MEASURES

Volumes of fetal total brain, cortical gray matter, white matter, deep gray matter, cerebellum, brainstem, and hippocampus were measured from 3-dimensional reconstructed T2-weighted MRI scans. Cortical folding measurements included local gyrification index, sulcal depth, and curvedness. Fetal brain N-acetylaspartate, creatine, and choline levels were quantified using 1H-MRS. Maternal stress, depression, and anxiety were measured with the Perceived Stress Scale (PSS), Edinburgh Postnatal Depression Scale (EPDS), Spielberger State Anxiety Inventory (SSAI), and Spielberger Trait Anxiety Inventory (STAI).

RESULTS

A total of 193 MRI studies were performed in 119 pregnant women (67 [56%] carrying male fetuses and 52 [44%], female fetuses; maternal mean [SD] age, 34.46 [5.95] years) between 24 and 40 gestational weeks. All women were high school graduates, 99 (83%) were college graduates, and 100 (84%) reported professional employment. Thirty-two women (27%) had positive scores for stress, 31 (26%) for anxiety, and 13 (11%) for depression. Maternal trait anxiety was associated with smaller fetal left hippocampal volume (STAI score: -0.002 cm3; 95% CI, -0.003 to -0.0008 cm3; P = .004). Maternal anxiety and stress were associated with increased fetal cortical gyrification in the frontal lobe (β for SSAI score: 0.004 [95% CI, 0.001-0.006; P = .002]; β for STAI score: 0.004 [95% CI, 0.002-0.006; P < .001]; β for PSS score: 0.005 [95% CI, 0.001-0.008; P = .005]) and temporal lobe (β for SSAI score: 0.004 [95% CI, 0.001-0.007; P = .004]; β for STAI score: 0.004 [95% CI, 0.0008-0.006; P = .01]). Elevated maternal depression was associated with decreased creatine (EPDS score: -0.04; 95% CI, -0.06 to -0.02; P = .005) and choline (EPDS score: -0.03; 95% CI, -0.05 to -0.01; P = .02) levels in the fetal brain.

CONCLUSIONS AND RELEVANCE

This study found that the prevalence of maternal psychological distress in healthy, well-educated, and employed pregnant women was high, underappreciated, and associated with impaired fetal brain biochemistry and hippocampal growth as well as accelerated cortical folding. These findings appear to support the need for routine mental health surveillance for all pregnant women and targeted interventions in women with elevated psychological distress.

The effect of maternal antidepressants on third trimester uteroplacental hemodynamics and the neonatal abstinence syndrome: a retrospective cohort study

The objective of this study is to determine whether maternal antidepressant use during pregnancy influences uteroplacental hemodynamics, thereby affecting fetal growth and gestational age at delivery. The secondary aim was to determine the incidence of neonatal abstinence syndrome (NAS) among infants exposed to antidepressant medications. The charts of women who received obstetrical care and had a history of depression from January 2014 to December 2016 at Mount Sinai Hospital in Toronto, Canada, were reviewed. Exclusion criteria were substance abuse; narcotic or lithium use at the time of delivery.In total, 205 women met the inclusion criteria (92 took antidepressants; 113 women did not). There were no significant differences in umbilical artery pulsatility index (PI), gestational age at delivery, or birth weight when comparing women based on antidepressant use. A small proportion (18%) of neonates had mild withdrawal symptoms; one baby had a score (≥ 8) consistent with severe NAS. In women with a history of depression, there was no difference in uteroplacental hemodynamics as measured by third trimester Doppler ultrasonography when comparing women who took antidepressant medication versus those who did not. The large majority of babies who were exposed to antidepressants in utero did not show withdrawal symptoms. These results lend support for the relative safety of antidepressants during pregnancy.

Cardiovascular effects of prenatal stress-Are there implications for cerebrovascular, cognitive and mental health outcome?

Prenatal stress programs offspring cognitive and mental health outcome. We reviewed whether prenatal stress also programs cardiovascular dysfunction which potentially modulates cerebrovascular, cognitive and mental health disorders. We focused on maternal stress and prenatal glucocorticoid (GC) exposure which have different programming effects. While maternal stress induced cortisol is mostly inactivated by the placenta, synthetic GCs freely cross the placenta and have different receptor-binding characteristics. Maternal stress, particularly anxiety, but not GC exposure, has adverse effects on maternal-fetal circulation throughout pregnancy, probably by co-activation of the maternal sympathetic nervous system, and by raising fetal catecholamines. Both effects may impair neurodevelopment. Experimental data also suggest that severe maternal stress and GC exposure during early and mid-gestation may increase the risk for cardiovascular disorders. Human data are scarce and especially lacking for older age. Programming mechanisms include aberrations in cardiac and kidney development, and functional changes in the renin-angiotensin-aldosterone-system, stress axis and peripheral and coronary vasculature. Adequate experimental or human studies examining the consequences for cerebrovascular, cognitive and mental disorders are unavailable.

Guided imagery for treating hypertension in pregnancy

BACKGROUND

Hypertension (high blood pressure) in pregnancy carries a high risk of maternal morbidity and mortality. Although antihypertensive drugs are commonly used, they have adverse effects on mothers and fetuses. Guided imagery is a non-pharmacological technique that has the potential to lower blood pressure among pregnant women with hypertension. Guided imagery is a mind-body therapy that involves the visualisation of various mental images to facilitate relaxation and reduction in blood pressure.

OBJECTIVES

To determine the effect of guided imagery as a non-pharmacological treatment of hypertension in pregnancy and its influence on perinatal outcomes.

SEARCH METHODS

We searched the Cochrane Pregnancy and Childbirth Group's Trials Register, and two trials registers (October 2018). We also searched relevant conference proceedings and journals, and scanned the reference lists of retrieved studies.

SELECTION CRITERIA

We included randomised controlled trials (RCTs). We would have included RCTs using a cluster-randomised design, but none were identified. We excluded quasi-RCTs and cross-over trials.We sought intervention studies of various guided imagery techniques performed during pregnancy in comparison with no intervention or other non-pharmacological treatments for hypertension (e.g. quiet rest, music therapy, aromatherapy, relaxation therapy, acupuncture, acupressure, massage, device-guided slow breathing, hypnosis, physical exercise, and yoga).

DATA COLLECTION AND ANALYSIS

Three review authors independently assessed the trials for inclusion, extracted data, and assessed risk of bias for the included studies. We checked extracted data for accuracy, and resolved differences in assessments by discussion. We assessed the certainty of the evidence using the GRADE approach.

MAIN RESULTS

We included two small trials (involving a total of 99 pregnant women) that compared guided imagery with quiet rest. The trials were conducted in Canada and the USA. We assessed both trials as at high risk of performance bias, and low risk of attrition bias; one trial was at low risk for selection, detection, and reporting bias, while the other was at unclear risk for the same domains.We could not perform a meta-analysis because the two included studies reported different outcomes, and the frequency of the intervention was slightly different between the two studies. One study performed guided imagery for 15 minutes at least twice daily for four weeks, or until the baby was born (whichever came first). In the other study, the intervention included guided imagery, self-monitoring of blood pressure, and thermal biofeedback-assisted relaxation training for four total hours; the participants were instructed to practice the procedures twice daily and complete at least three relief relaxation breaks each day. The control groups were similar - one was quiet rest, and the other was quiet rest as bed rest.None of our primary outcomes were reported in the included trials: severe hypertension (either systolic blood pressure of 160 mmHg or higher, or diastolic blood pressure of 110 mmHg or higher); severe pre-eclampsia, or perinatal death (stillbirths plus deaths in the first week of life). Only one of the secondary outcomes was measured.Low-certainty evidence from one trial (69 women) suggests that guided imagery may make little or no difference in the use of antihypertensive drugs (risk ratio 1.27, 95% confidence interval 0.72 to 2.22).

AUTHORS' CONCLUSIONS

There is insufficient evidence to inform practice about the use of guided imagery for hypertension in pregnancy.The available evidence for this review topic is sparse, and the effect of guided imagery for treating hypertension during pregnancy (compared with quiet rest) remains unclear. There was low-certainty evidence that guided imagery made little or no difference to the use of antihypertensive drugs, downgraded because of imprecision.The two included trials did not report on any of the primary outcomes of this review. We did not identify any trials comparing guided imagery with no intervention, or with another non-pharmacological method for hypertension.Large and well-designed RCTs are needed to identify the effects of guided imagery on hypertension during pregnancy and on other relevant outcomes associated with short-term and long-term maternal and neonatal health. Trials could also consider utilisation and costs of health service.

Dependencies between maternal and fetal autonomic tone

Background Disturbances in maternal physiology can cause changes in the fetal condition that may lead to impaired fetal development. Synchronous monitoring of cardiac autonomic tone via the assessment of the fetal and maternal heart rate (HR) and heart rate variability (HRV) may provide an appropriate diagnostic window. Methods Partial rank correlation coefficients between the maternal and fetal HR and HRV indices were calculated and verified by testing surrogate data in 315 magnetocardiographic (MCG) recordings from 141 healthy women pregnant with singleton fetuses [18+6 to 39+2 weeks gestational age (WGA)]. We assessed maternal self-perceived depression, anxiety and stress by means of the Depression, Anxiety, Stress Scales self-reporting instrument (DASS42G) questionnaire. Results The maternal HRV correlated positively with the fetal HRV, but negatively with the fetal HR. Correlation was |r|<0.2 in state-independent and gestational age (GA) <32 weeks, but |r|>0.2 in active sleep and GA ≥32 weeks. The DASS42G results correlated with the maternal HRV and HR, while the fetal HR and HRV were not influenced. Conclusion Correlations between maternal and fetal autonomic activation were statistically confirmed. They depend on the GA and active fetal state. As far as healthy subjects are concerned, maternal self-perceived stress, anxiety or depression is mirrored in maternal but not in fetal autonomic tone.

Understanding the antepartum depressive symptoms and its risk factors among the pregnant women visiting public health facilities of Nepal

INTRODUCTION

Antepartum depression is a contributing factor for adverse maternal and perinatal outcome. The study aimed to assess the antepartum depressive symptoms in selected public health facilities of Nepal.

METHODOLOGY

This is a mixed-method cross-sectional study that included 143 pregnant women attending the antenatal checkup in four public health facilities of Kathmandu. Edinburgh Postnatal Depression Scale (EPDS) tool with cut-off score > = 10 was used to assess the antepartum depressive symptoms. Bivariate and multivariable analysis was carried out to identify factors associated with the depressive symptoms. Further semi-structured interviews were conducted with 12 pregnant women identified with the depressive symptoms.

RESULT

Of the total 143 pregnant women, 26 (18%, CI at 95% 12.6-25.5) reported depressive symptoms. Multivariable analysis reported higher odds of antepartum depressive-symptoms with health problem, early gestational age, sex preference, and spousal alcohol intake. Thematic analysis of qualitative data further revealed participants' apprehension on; birth outcome, a family expectation of male child, inadequate support from the family/husband and disturbed family environment.

CONCLUSION

Notable proportion of pregnant women were reported with antepartum depressive symptoms. Women's perception on patriarchal values for childbirth was revealed to be important factor for the depressive symptoms. The study draws an attention to a need for screening for antepartum depression into primary health care system. Strengthening ongoing efforts on gender equity could contribute the psychological well-being of pregnant women.

Prenatal maternal anxiety and children's brain structure and function: A systematic review of neuroimaging studies

BACKGROUND

Maternal anxiety disorders are common during pregnancy and postpartum, and are associated with increased behaviour problems and risk of mental health difficulties in children. Understanding alterations in brain structure and function associated with maternal anxiety may help elucidate potential mechanisms via which high maternal anxiety could affect children.

METHODS

We conducted a systematic review of extant research studying the associations between prenatal anxiety and children's brain structure and function, as assessed through neuroimaging. Data were gathered in accordance with the PRISMA review guidelines.

RESULTS

Ten articles were identified, and all found a significant association between antenatal maternal anxiety and child neurodevelopment. Studies vary considerably in their methods with five studies employing electroencephalography (EEG), one using magnetoencephalography (MEG), and the rest employing magnetic resonance imaging (MRI).

LIMITATIONS

The heterogeneity of neuroimaging techniques undertaken by the reviewed studies precluded a meta-analysis from being performed. The applicability of this systematic review to clinical practice is also limited given that the studies examined children across a wide age range (neonates to 17 years).

CONCLUSIONS

From early infancy to late adolescence, findings suggest alterations of brain structure and function in frontal, temporal, and limbic areas in children born to mothers who experienced prenatal anxiety. These brain abnormalities may underlie associations between prenatal anxiety and children's behaviour, though more research incorporating neuroimaging and behavioural data is necessary to determine this.

Maternal psychological distress during pregnancy and childhood health outcomes: a narrative review

Maternal psychological distress is common in pregnancy and may influence the risk of adverse outcomes in children. Psychological distress may cause a suboptimal intrauterine environment leading to growth and developmental adaptations of the fetus and child. In this narrative review, we examined the influence of maternal psychological distress during pregnancy on fetal outcomes and child cardiometabolic, respiratory, atopic and neurodevelopment-related health outcomes. We discussed these findings from an epidemiological and life course perspective and provided recommendations for future studies. The literature in the field of maternal psychological distress and child health outcomes is extensive and shows that exposure to stress during pregnancy is associated with multiple adverse child health outcomes. Because maternal psychological distress is an important and potential modifiable factor during pregnancy, it should be a target for prevention strategies in order to optimize fetal and child health. Future studies should use innovative designs and strategies in order to address the issue of causality.
