The Serotonin-Immune Axis in Preeclampsia

PURPOSE OF REVIEW

To review the literature and detail the potential immune mechanisms by which hyperserotonemia may drive pro-inflammation in preeclampsia and to provide insights into potential avenues for therapeutic discovery.

RECENT FINDINGS

Preeclampsia is a severe hypertensive complication of pregnancy associated with significant maternal and fetal risk. Though it lacks any effective treatment aside from delivery of the fetus and placenta, recent work suggests that targeting serotonin systems may be one effective therapeutic avenue. Serotonin dysregulation underlies multiple domains of physiologic dysfunction in preeclampsia, including vascular hyporeactivity and excess platelet aggregation. Broadly, serotonin is increased across maternal and placental domains, driven by decreased catabolism and increased availability of tryptophan precursor. Pro-inflammation, another hallmark of the disease, may drive hyperserotonemia in preeclampsia. Interactions between immunologic dysfunction and hyperserotonemia in preeclampsia depend on multiple mechanisms, which we discuss in the present review. These include altered immune cell, kynurenine pathway metabolism, and aberrant cytokine production mechanisms, which we detail. Future work may leverage animal and in vitro models to reveal serotonin targets in the context of preeclampsia's immune biology, and ultimately to mitigate vascular and platelet dysfunction in the disease. Hyperserotonemia in preeclampsia drives pro-inflammation via metabolic, immune cell, and cytokine-based mechanisms. These immune mechanisms may be targeted to treat vascular and platelet endophenotypes in preeclampsia.

Post-traumatic stress disorder in the perinatal period: A concept analysis

AIMS AND OBJECTIVES

To report an analysis of the concept of perinatal post-traumatic stress disorder.

BACKGROUND

Prevalence of perinatal post-traumatic stress disorder is rising in the USA, with 9% of the U.S. perinatal population diagnosed with the disorder and an additional 18% being at risk for the condition. Left untreated, adverse maternal-child outcomes result in increased morbidity, mortality and healthcare costs.

DESIGN

Concept analysis via Walker and Avant's approach.

METHODS

The databases Cumulative Index to Nursing and Allied Health Literature (CINAHL), Medline, Academic Search Premier and PsychINFO were searched for articles, written in English, published between 2006-2015, containing the terms perinatal and post-traumatic stress disorder.

RESULTS

Perinatal post-traumatic stress disorder owns unique attributes, antecedents and outcomes when compared to post-traumatic stress disorder in other contexts, and may be defined as a disorder arising after a traumatic experience, diagnosed any time from conception to 6 months postpartum, lasting longer than 1 month, leading to specific negative maternal symptoms and poor maternal-infant outcomes. Attributes include a diagnostic time frame (conception to 6 months postpartum), harmful prior or current trauma and specific diagnostic symptomatology defined in the Diagnostic and Statistical Manual of Mental Disorders, 5th edition. Antecedents were identified as trauma (perinatal complications and abuse), postpartum depression and previous psychiatric history. Consequences comprised adverse maternal-infant outcomes.

CONCLUSIONS

Further research on perinatal post-traumatic stress disorder antecedents, attributes and outcomes in ethnically diverse populations may provide clinicians a more comprehensive framework for identifying and treating perinatal post-traumatic stress disorder.

RELEVANCE TO CLINICAL PRACTICE

Nurses are encouraged to increase their awareness of perinatal post-traumatic stress disorder for early assessment and intervention, and prevention of adverse maternal-infant outcomes.

Computer-Assisted Qualitative Data Analysis Software, Phenomenology, and Colaizzi's Method

Technology is widely used to support qualitative research. Computer-Assisted Qualitative Data Analysis Software (CAQDAS) encompasses complementary technologies to support qualitative analysis. Advantages of CAQDAS include efficient management of data and transparency in analysis. Disadvantages include heavy emphasis on coding as a distractor from analysis and considerable time to learn the program. In this methods article, we, as less experienced, qualitative researchers describe our experiences using NVivo, a CAQDAS program, in a descriptive phenomenological study using Colaizzi's method. Over 1 year, 24 postpartum women were given a secure research link to record their experiences with pain and depression during the third trimester of pregnancy. Although NVivo analysis was helpful, the philosophy of phenomenology, reflexivity, and Colaizzi's method directed researchers away from NVivo for the final summation. Recommendations for future use of CAQDAS used concurrently with Colaizzi's method include the use of word clouds and other visualizations for bracketing and triangulation.

Community Health Workers and Use of mHealth: Improving Identification of Pregnancy Complications and Access to Care in the Dominican Republic

This article presents the feasibility and acceptability of using mobile health technology by community health workers (CHWs) in San Juan Province, Dominican Republic, to improve identification of pregnancy complications and access to care for pregnant women. Although most women in the Dominican Republic receive four antenatal care visits, poor women and adolescents in remote areas are more likely to have only one initial prenatal visit to verify the pregnancy. This community-based research began when community leaders raised concern about the numbers of their mothers who died in childbirth annually; San Juan's maternal mortality rate is 144/100,000 compared to the Caribbean rate of 85/100,000. Eight CHWs in three communities were taught to provide third-trimester antenatal assessment, upload the data on a mobile phone application, send the data to the local physician who monitored data for "red flags," and call directly if a mother had an urgent problem. Fifty-two pregnant women enrolled, 38 were followed to delivery, 95 antenatal care postintake were provided, 2 urgent complications required CHW home management of mothers, and there were 0 deaths. Stakeholders endorsed acceptability of intervention. Preliminary data suggest CHWs using mobile health technology is feasible, linking underserved and formal health care systems with provision of primary care in mothers' homes.

Stigma Experienced by Perinatal Women with Opioid Dependency in the United States: A Qualitative Meta-Synthesis

Stigma is a barrier to accessing care and treatment for perinatal women with pain and opioid dependency, resulting in increased maternal/neonatal morbidity and mortality, prolonged neonatal hospitalizations, and increased healthcare-related costs. This theory-generating qualitative meta-synthesis includes 18 qualitative research reports and describes the stigma-related experiences of perinatal women with opioid dependency. A model emerged consisting of cyclical yet pivotal care points, facilitators/deterrents of stigma, and stigma experiences including infant-associative stigma. Findings of this qualitative meta-synthesis include the following: (a) Perinatal stigma experiences may prevent women from accessing care; (b) Infant-associative stigma may influence the woman to deflect stigma from her infant onto herself; and (c) There is the risk of mothers withdrawing their infants from healthcare to protect from future anticipated stigma. Implications reveal ideal time points to enact healthcare interventions to reduce perinatal stigma experiences and its consequences on maternal/child health and wellness.

Use and Misuse of Opioid Pain Medications by Pregnant and Nonpregnant Women

BACKGROUND

The use and misuse of opioid pain medication is a public health problem that has extended to pregnant women. Assessing both the use and misuse of opioid pain medication had been limited.

AIMS

The aim of the present study was to disseminate data from a national sample of pregnant and nonpregnant women, tracking the rate and predictors of opioid use and misuse.

METHODS

In 2015 the National Survey on Drug Use and Health expanded the assessment of opioid pain reliever use and misuse. Here, a secondary analysis of 2 years of National Survey on Drug Use and Health expanded data assesses the use and misuse of opioids in pregnant and nonpregnant women ranging in age from 18 to 44 years (N = 46,229).

RESULTS

Opioid medication use was reported by 31.89% of pregnant women and 38.87% of nonpregnant women. Race and pregnancy status were associated with risk, with pregnancy being protective and White women having significantly higher risk.

CONCLUSIONS

The high rates of use and misuse of opioids in pregnant women underscores a critical need for screening for opioid use and misuse, particularly among White women. Pregnancy provides a unique window of opportunity to educate, screen, and provide treatment.

The Lived Experience of Pain and Depression Symptoms during Pregnancy

BACKGROUND

Depressive symptoms and pain are prevalent during pregnancy. Untreated pain and depressive symptoms occurring together may have a negative effect on maternal and newborn outcomes, yet little is known about women's experiences with pain and depressive symptoms during pregnancy. The purpose of this study is to describe the lived experience of depressive symptoms and pain occurring in women during the third trimester of pregnancy.

METHODS

A descriptive phenomenological study was conducted. Women during postpartum were recruited from a previous cross-sectional study of women in their third trimester that evaluated the relationship between pain, depression, and quality of life. Twenty-four women entered their responses into an online secure research Web site. These data were analyzed using Colaizzi's method of descriptive phenomenological analysis.

RESULTS

Four themes that described the essence of women's experiences with both pain and depressive symptoms were identified. They were pregnancy: feeling minimized, unheard and overwhelmed; attempting or trying but not treated: living with pain and pain interference; pain, sleep loss, and suffering; and pain and depressive symptoms: helpless, hopeless, and suffering.

CLINICAL IMPLICATIONS

If a woman presents with pain, additional nursing assessments of her sleep and emotional state may be needed. Likewise, a positive depression symptom screening suggests the need for a more in-depth exploration of pain, pain interference, poor sleep, and mental health symptoms. Because the women perceive their pregnancy as minimized, nurses may need to assist in setting realistic expectations and encouraging social support. Nurses listening to women describing these conditions may be essential in promoting the women's wellbeing.

Selective serotonin reuptake inhibitors and preeclampsia: A quality assessment and meta-analysis

Serotonin modulates vascular, immune, and neurophysiology and is dysregulated in preeclampsia. Despite biological plausibility that selective serotonin reuptake inhibitors (SSRIs) prevent preeclampsia pathophysiology, observational studies have indicated increased risk and providers may be hesitant. The objective of this meta-analysis and quality assessment was to evaluate the evidence linking SSRI use in pregnancy to preeclampsia/gestational hypertension. PubMed was searched through June 5, 2020 manually and using combinations of terms: "preeclampsia", "serotonin", and "SSRI". This review followed MOOSE guidelines. Inclusion criteria were: 1) Observational cohort or population study, 2) exposure defined as SSRI use during pregnancy, 3) cases defined as preeclampsia or gestational hypertension, and 4) human participants. Studies were selected that addressed the hypothesis that gestational SSRI use modulates preeclampsia and/or gestational hypertension risk. Review Manager Web was used to synthesize study findings. Articles were read and scored (Newcastle-Ottawa Quality Assessment Scale) for quality by two independent reviewers. Publication bias was assessed using a funnel plot and the Egger test. Of 179 screened studies, nine were included. The pooled risk ratio (random effects model) was 1.43 (95 % CI: 1.15-1.78, P < 0.001; range 0.96-4.86). Two studies were rated as moderate quality (both with total score of 6); others were high quality. Heterogeneity was high (I2 = 88 %) and funnel asymmetry was significant (p < 0.00001). Despite evidence for increased preeclampsia risk with SSRIs, shared risk factors and other variables are poorly controlled. Depression treatment should not be withheld due to perceived gestational hypertension risk. Mechanistic evidence for serotonin modulation in preeclampsia demonstrates a need for future research.

Correlates of Perinatal Post-Traumatic Stress among Culturally Diverse Women with Depressive Symptomatology

Post-traumatic stress disorder (PTSD) is an important and often neglected comorbidity of pregnancy; left untreated, it can lead to serious health complications for the mother and developing fetus. Structured interviews were conducted to identify risk factors of PTSD among culturally diverse women with depressive symptomatology receiving perinatal services at community obstetric/gynecologic clinics. Women abused as adults, with two or more instances of trauma, greater trauma severity, insomnia, and low social support were more likely to present perinatal PTSD symptoms. Perinatal PTSD is prevalent and has the potential for chronicity. It is imperative healthcare providers recognize salient risk factors and integrate culturally sensitive screening, appropriate referral, and treatment services for perinatal PTSD.

Pathways from pain to physical and mental health-related quality of life during the third trimester of pregnancy: an exploratory mediation analysis

AIMS AND OBJECTIVES

To understand how pain affects physical and mental health-related quality of life during the third trimester of pregnancy.

BACKGROUND

Poor health-related quality of life during pregnancy is associated with adverse maternal foetal health outcomes such as increased risk of low-birth-weight neonates. Poor health-related quality of life is linked to pain, pain interference and anxiety in the general adult population. However, we do not know how pain, pain interference (i.e., interference of pain with patient function), and anxiety are interrelated during the third trimester of pregnancy.

METHODS

This exploratory cross-sectional study followed STROBE guidelines. A mobile educational and tracking pregnancy application was used to obtain a racially/ethnically diverse convenience sample of 141 third trimester pregnant women from the U. S. In this sample, 58.2% of women had commercial health insurance, 68.8% were Caucasian, 86.5% were younger than 35 years, and 85.1% had a partner. Women completed demographics, Edinburgh Postnatal Depression Scale and the Brief Pain Inventory on REDCap. Path analysis was used to investigate a model for the relationships among pain intensity, pain interference, anxiety and physical and mental health-related quality of life.

RESULTS

Pain intensity affected health-related quality of life indirectly by increasing pain interference, which in turn, decreased both physical and mental health-related quality of life. In addition, pain interference also increased anxiety, which in turn worsened mental health-related quality of life, but not physical health-related quality of life.

CONCLUSIONS

Treating perinatal pain may improve health-related quality of life by decreasing pain interference and anxiety.

RELEVANCE TO CLINICAL PRACTICE

Nurses should assess for pain interference and anxiety in women experiencing moderate to severe pain during the third trimester of pregnancy. With this knowledge, nurses may advocate for women in receiving effective treatment for their conditions and improvements in their physical and mental health-related quality of life.

Abstract 30: Role For Adverse Childhood Experiences And Depression In Preeclampsia

Hypertensive diseases are associated with adverse experiences in childhood as well as depression. In order to determine if these associations were present in women with preeclampsia (PreE), a particularly devastating hypertensive disease in pregnancy, the scores from three questionnaires: Adverse Childhood Experiences (ACE), Edinburgh Postnatal Depression Scale (EPDS), and the Patient Health Questionnaire-9 (PHQ-9) were compared between women with PreE (n=32) and women without PreE (n=46) between 9 and 48 months postpartum (IRB# 201808705). ACE scores are calculated by summing an individual’s affirmative responses to specific adverse experiences during childhood. In our study, the average ACE score of individuals with PreE was higher than that of women without PreE (1.69 vs. 1.02, P=.04). We also divided women into groups based on whether their ACE score was ≤3 or ≥4 due to evidence that individuals who have experienced ≥4 ACEs are at greatest risk for physical and mental health conditions. Among our participants, 80% of women with an ACE score ≥4 (n=10) had PreE while only 35.3% of women with a score ≤3 (n=68) developed the condition (P=0.01). As well, the odds of having PreE were higher in those with ACE scores ≥4, compared with those with scores ≤3 (OR= 7.34; 95% CI = 1.44, 37.33). In a subset of participants, scores were available from EPDS, survey that identifies women who have postpartum depression 6 weeks after birth, and from the PHQ-9, another assessment for depression. Among our participants, the average EPDS score was higher in women with PreE than women without PreE (6.38, n=21 vs. 3.71, n=42 P=0.01), indicating more severe symptoms of postpartum depression in women who also had PreE. In addition, the average PHQ-9 score among women with PreE was higher than that of women without PreE (3.71, n=15 vs 1.86, n=37 P=.02) with a higher score indicating more severe depression. The average PHQ-9 score was also higher in women who had ACE scores ≥4 than women with scores ≤3 (4.00, n=4 vs. 2.27, n=48 P=.01) indicating that women with more adverse childhood events were more likely to experience depression. Together, these findings indicate that PreE may be associated with adverse events during childhood as well as depression in late pregnancy and/or postpartum.

Over-the-Counter Pain Medication Use During Pregnancy

PURPOSE

To examine over-the-counter pain medication use in pregnancy.

STUDY DESIGN AND METHODS

Secondary analysis of a weighted surveillance survey using the 2019 Iowa Pregnancy Risk Assessment Monitoring System (PRAMS) data. A sample of 759 pregnant women of childbearing age from Iowa was weighted to represent 31,728 Iowa mothers. The weighted sample represents 80% non-Hispanic White mothers, with smaller percentages of Hispanic (10%) mothers and non-Hispanic Black (7%) mothers, consistent with the population of Iowa. Approximately two-thirds of women had commercial insurance (66%), some college or greater education (62%), and were from urban areas (59%).

ANALYSIS

Descriptive statistics were calculated. Variables include over-the-counter pain reliever usage among all respondents and by race/ethnicity and education level.

RESULTS

Seventy-six percent of women reported taking over-the-counter pain relievers during pregnancy. Of these, 71% reported taking acetaminophen, 11% reported taking ibuprofen, 8% aspirin, and 3% naproxen. Nearly 80% of non-Hispanic White mothers reported taking an over-the-counter pain reliever during pregnancy compared to just 64% of mothers reported as Hispanic. Iowa mothers with a college education or greater were more likely to report over-the-counter pain reliever use during pregnancy (84%) than their counterparts with a high school education or less (64%).

CLINICAL IMPLICATIONS

Some medications may cause harm to the fetus if taken at specific time during pregnancy. Reinforcement of current pain medication education, including risks to fetus throughout pregnancy may be needed.

Validation of the Patient-Reported Outcomes Measurement Information System Pain Intensity and Brief Pain Inventory During Pregnancy

OBJECTIVES

We sought to (1) validate the Patient-Reported Outcomes Measurement Information System (PROMIS) Pain Intensity Short Form 3a measure and Brief Pain Inventory (BPI) for assessing pain during pregnancy and (2) evaluate pain in a sample of pregnant individuals.

METHODS

Pregnant individuals (N = 196) were prospectively surveyed: n = 171 up to 22 weeks gestational age, n = 123 during their third trimester of pregnancy, and n = 98 both times. Additional measures included SPRINT Post-Traumatic Stress Disorder Tool, Neurological Quality of Life, Edinburgh Postnatal Depression Scale and anxiety subscale, and Adverse Childhood Experiences Questionnaire. Validity evidence examined included content validity, reliability, convergent and discriminant validity, and relevant criterion relationships.

RESULTS

Content validity analysis suggests that the PROMIS pain measure was easy to use and interpret while the BPI provided more detail. However, BPI questions regarding medication usage and relief were unclear to some pregnant individuals. In addition, the relationships among pain ratings were stronger than relationships between pain ratings and measures intended to assess other constructs suggesting convergent and discriminant validity. Relationships with relevant criterions were presented for both the PROMIS and BPI by comparing ratings of pain intensity and severity for pregnant individuals with and without areas of pain reported on BPI.

CONCLUSION

Results indicate that PROMIS and BPI provided valid information on pain intensity or severity for our perinatal sample. Depending on the research question, the PROMIS pain or BPI may be more appropriate to an individual study. Either measure could also be included in an electronic health record for accurate pain assessment in clinical settings.

A role for adverse childhood experiences and depression in preeclampsia

Introduction

Adverse childhood experiences (ACEs) are a measure of childhood adversity and are associated with life-long morbidity. The impacts of ACEs on peripartum health including preeclampsia, a common and dangerous hypertensive disorder of pregnancy, remain unclear, however. Therefore, we aimed to determine ACE association with peripartum psychiatric health and prevalence of preeclampsia using a case-control design.

Methods

Clinical data were aggregated and validated using a large, intergenerational knowledgebase developed at our institution. Depression symptoms were measured by standard clinical screeners: the Patient Health Questionnaire-9 (PHQ-9) and the Edinburgh Postnatal Depression Scale (EPDS). ACEs were assessed via survey. Scores were compared between participants with (N = 32) and without (N = 46) prior preeclampsia.

Results

Participants with ACE scores ≥4 had significantly greater odds of preeclampsia than those with scores ≤ 3 (adjusted odds ratio = 6.71, 95% confidence interval:1.13-40.00; p = 0.037). Subsequent speculative analyses revealed that increased odds of preeclampsia may be driven by increased childhood abuse and neglect dimensions of the ACE score. PHQ-9 scores (3.73 vs. 1.86, p = 0.03), EPDS scores (6.38 vs. 3.71, p = 0.01), and the incidence of depression (37.5% vs. 23.9%, p = 0.05) were significantly higher in participants with a history of preeclampsia versus controls.

Conclusions

Childhood sets the stage for life-long health. Our findings suggest that ACEs may be a risk factor for preeclampsia and depression, uniting the developmental origins of psychiatric and obstetric risk.

The Interdisciplinary Doula Project: Innovations in Nursing Clinical Education

ABSTRACT

People giving birth report overwhelmingly positive experiences with nursing students acting as doulas. However, no programs report on improving diversity among students, pregnant people, and curricula. This article describes the Interdisciplinary Doula Project, a program to enhance diverse perspectives and clinical skills of university students. Nursing ( n = 21, 77.8%) and other health students ( n = 6, 22.2%) completed doula training, diversity seminars, and 36 hours of intrapartum care. Seven nursing students were hired to work on labor and delivery upon graduation. This innovative program may increase registered nurses trained to provide culturally congruent labor support for vulnerable pregnant populations.
