Integrative Review of Black Birthing People's Interactions With Clinicians During the Perinatal Period.

Maternal morbidity and mortality disproportionately affect Black birthing people. Multiple factors contribute to these disparities, including variations in quality health care, structural racism, and implicit bias. Interactions between Black patients and perinatal clinicians could further affect perinatal care use and subsequent perinatal outcomes. This integrative review aims to synthesize quantitative and qualitative literature published in peer-reviewed journals in English within the past 10 years that address patient-clinician interactions during the perinatal period for Black birthing people in the United States. A systematic search of CINAHL, PubMed, PsycINFO, MEDLINE, and Embase recovered 24 articles that met the eligibility criteria for inclusion in this review. The following themes emerged from synthesizing Black patients' interactions with perinatal clinicians: Care Quality, Communication, Power Dynamic, and Established Relationships. Mutual respect, effective communication, and shared decision-making may be key modifiable factors to address through clinician education to improve perinatal care for many Black persons.

Neonatal nurse practitioner job satisfaction, workforce environment, and mental well-being.

BACKGROUND: Increased demand for nurse practitioners emphasizes the importance of consistent and ongoing collection of data to provide a better understanding of the NNP workforce and to promote retention and recruitment of NNPs. PURPOSE: To understand how work environment and work hours influence job or career satisfaction. METHODOLOGY: The National Association of Neonatal Nurse Practitioners in collaboration with the National Certification Corporation emailed an online survey to all 6,558 certified neonatal nurse practitioners (NNPs) in 2020 with 845 (12.8%) responding. Subjects included those with responsibilities in direct patient care, transport NPs, faculty/directors, and advanced practice registered nurse coordinators/managers/administrators. RESULTS: Satisfaction with career choice as an NNP was reported as very satisfied by 58% (n = 493) and mostly satisfied by 37% (n = 310). Satisfaction with current job as an NNP was reported as very satisfied for 30% (n = 252), with 51% being mostly satisfied (n = 435). Age influenced satisfaction scores, with NNPs aged 61 years or older having a higher mean score than NNPs aged 31-40 years ( p = .041). The majority of NNPs did not use all of their available paid time off (72%; n = 609) and respondents worked an additional 248 extra hours per year. NNPs experience bullying (58%) and/or lateral violence (32%). Seventeen percent have called in sick for mental health reasons (n = 147). CONCLUSIONS: Neonatal nurse practitioners' satisfaction is multifactorial. Those who reported taking time off for self-prescribed mental health indicated less job satisfaction, more work hours, poor work/life balance, and a less-than-optimum work environment. IMPLICATIONS: Overall, NNPs are satisfied with their career choice but are less satisfied with their job choice. Understanding factors that influence mental well-being and job satisfaction will improve recruitment and retention of nurse practitioners.

A Review of the NANN Research Summit Experience: Continuing to Promote a Platform for Research and Clinical Inquiry.

BACKGROUND: The NANN Research Summit has been providing a platform for neonatal scholarship and clinical inquiry for 15 years. As the discipline of nursing and nursing research continue to evolve, it is important to gain perspective on current trends and needs for areas of strength and growth. PURPOSE: To evaluate participant outcomes of the NANN Research Summit and determine opportunities for improvement. METHODS: A 9-question survey was sent to 90 past participants for the Research Summit years 2015-2019. RESULTS: Thirty-seven (41%) participants from 2015 to 2019 responded. Of those responding, 75% continued to pursue their presentation topic; 95% felt empowered to continue their research based on their Summit experience; 84% felt more comfortable presenting their research findings after attending; 84% felt confident in publishing research after attending the Summit, with 43% reporting publications. These accomplished results would not have been possible without Mead Johnson's support. In addition, 57% did not publish the work presented and 65% lacked continued mentorship. IMPLICATIONS FOR PRACTICE: A redesigned Summit is presented to address the priorities for growth and alignment with continued emphasis on collegiality among neonatal nurse scholars. The redesigned Summit will promote continued clinical inquiry as a result of intentional focus on mentorship and development of scholarship. IMPLICATIONS FOR RESEARCH: The data collected from this initial survey will continue to serve as the basis for future data collection. Continued evaluation of strengths and areas for growth including the number of publications and mentorship experience can lead to expansion of research for the Summit facilitators and participants.

Cytokine levels throughout the perinatal period.

BACKGROUND: Dysregulation of inflammatory processes is linked to perinatal complications yet a comprehensive description of cytokine levels throughout the perinatal period is lacking. We report prospective, serial levels of 29 unique cytokines measured in maternal blood during pregnancy, in the cord blood at birth, and in the neonatal blood. METHODS: Pregnant women (n = 140) for recruited from a Midwest tertiary medical center. Blood was obtained at five timepoints: 12-20 weeks, 24-28 weeks, and at labor in the women, umbilical cord at birth, 24-72 h in the newborn. Cytokine levels were analyzed using an electrochemiluminescence-based immunoassay. RESULTS: Levels for 29 cytokines were measured. The data were separated into two groups: pregnancies with (n = 82) and without major complications (n = 53) (preterm birth, preeclampsia, diabetes mellitus). Eighteen cytokines showed significant changes over time (p < .002). The majority of the cytokines were highest in the newborn. No differences in cytokine levels between complication groups were noted at any timepoint. CONCLUSIONS: This is the first known study to report prospective, serial cytokine levels throughout the perinatal period for pregnancies with/without complications. No differences in maternal cytokine levels between those with/without complications were detected; studies with a larger sample size would be needed to validate our current findings. Results also suggest cytokine dysregulation may be more localized to the placenta making it difficult to measure and predict during pregnancy using maternal systemic blood specimens.

Parents' pandemic NICU experience in the United States: a qualitative study.

BACKGROUND: Prior to the COVID-19 pandemic, parents of infants in the Neonatal Intensive Care Unit (NICU) frequently reported high levels of stress, uncertainty, and decreased parenting confidence. Early research has demonstrated that parents have had less access to their infants in the hospital due to restrictions on parental presence secondary to the pandemic. It is unknown how parents have perceived their experiences in the NICU since the beginning of the COVID-19 pandemic. The purpose of this study was to describe the lived experience of parents who had an infant in the NICU in the context of the COVID-19 pandemic to inform healthcare providers and policy makers for future development of policies and care planning. METHODS: The study design was a qualitative description of the impact of the COVID-19 pandemic on parents' experiences of having an infant in the NICU. Free-text responses to open-ended questions were collected as part of a multi-method study of parents' experiences of the NICU during the first six months of the pandemic. Participants from the United States were recruited using social media platforms between the months of May and July of 2020. Data were analyzed using a reflexive thematic approach. FINDINGS: Free-text responses came from 169 parents from 38 different states in the United States. Three broad themes emerged from the analysis: (1) parents' NICU experiences during the COVID-19 pandemic were emotionally isolating and overwhelming, (2) policy changes restricting parental presence created disruptions to the family unit and limited family-centered care, and (3) interactions with NICU providers intensified or alleviated emotional distress felt by parents. A unifying theme of experiences of emotional distress attributed to COVID-19 circumstances ran through all three themes. CONCLUSIONS: Parents of infants in the NICU during the first six months of the COVID-19 pandemic experienced emotional struggles, feelings of isolation, lack of family-centered care, and deep disappointment with system-level decisions. Moving forward, parents need to be considered essential partners in the development of policies concerning care of and access to their infants.

Impacts of Neonatal Hospitalization on Families during the 2019 Coronavirus Pandemic.

OBJECTIVE: Limited data are available regarding family and financial well-being among parents whose infants were hospitalized during the 2019 coronavirus (COVID-19) pandemic. The study objective was to evaluate the family and financial well-being of parents whose infants were hospitalized in the neonatal intensive care unit (NICU) during COVID-19. STUDY DESIGN: Parents were recruited for this online, cross-sectional survey via support groups on social media. Data collection was completed between May 18, 2020 and July 31, 2020. The final sample consisted of 178 parents, who had an infant hospitalized in an NICU between February 1, 2020 and July 31, 2020. The primary outcomes were impact on family life and financial stability, as measured by the Impact on Family scale, an instrument that evaluates changes to family life as a result of infant or childhood illness. RESULTS: Of the 178 parent respondents, 173 (97%) were mothers, 107 (59.4%) were non-Hispanic White, and 127 (69.5%) of the infants were born prematurely. Parents reported significant family impact and greater financial difficulty. Extremely premature infants, lower household income, parent mental health, and lower parental confidence were predictive of greater impacts on family life. CONCLUSION: Parents reported significant family and financial impacts during their infant's hospitalization amid COVID-19. Further studies are needed to guide clinical practice and inform family-supportive resources that can mitigate consequences to family well-being. KEY POINTS: · Impact of infant hospitalization in the context of COVID-19 is largely unknown.. · In a cohort of NICU parents during COVID-19, they reported changes to family life and finances.. · Greater impacts were reported by parents with lower income, confidence, and very premature infants..

2020 Neonatal Nurse Practitioner Workforce Survey: An Executive Summary.

BACKGROUND: The National Association of Neonatal Nurse Practitioners (NANNP) partnered with the National Certification Corporation (NCC) to invite all NCC-certified neonatal nurse practitioners (NNPs) to participate in a national survey on NNP compensation, workforce environment, and satisfaction measures. PURPOSE: To understand the current NNP compensation, benefits, and workforce environment. METHODS: An anonymous survey was sent to 6558 board-certified NNPs with 845 respondents. RESULTS: Most of the survey respondents (92%) are in direct patient care (n = 804) with 83% (n=703) working full time (35 hours or more). Those NNPs with less than 5 years' experience had a mean salary of $119,000 per year while more experienced NNPs (30-plus years) earned a mean salary of $134,000 per year. Half of the NNPs (51%) report high satisfaction with their scope of practice and role in their organization. Distribution of NNPs throughout the workforce is suboptimal, with 67% of the administrators indicating they do not have enough NNPs. IMPLICATIONS FOR PRACTICE AND RESEARCH: The 2020 NANNP workforce survey collected information on NNP compensation, benefits, work environment, and experiences. It identified areas of satisfaction, such as compensation with bonuses and pay increases, and acknowledged areas needing improvement such as the lack of diversity within the profession. Utilizing the results of the survey will help create a more diverse, well-educated, and informed workforce to ensure culturally competent NNPs remain relevant within the healthcare system.

Pregnant Mexican American Biopsychosocial/Cultural risks for adverse infant outcomes.

AIMS: To test a model of psychosocial/cultural/biological risk factors for poor birth outcomes in Latina pregnant women. DESIGN: An observational study measuring acculturation, progesterone, cortisol, cotinine, age, marital status, income, stress, depressive symptoms and coping. We tested a structural equation model to predict risk. METHODS: We obtained a convenience sample (N = 515) of low medical risk pregnant Mexican American Hispanic women at 22-24 weeks of gestation. Bilingual research nurses collected data from blood, urine and questionnaires. Self-report measures were the Beck Depression Inventory-II, the Perceived Stress Scale, the Acculturation Rating Scale for Mexican Americans-II and the Brief Cope. We measured progesterone and cortisol in plasma and cotinine levels in urine by enzyme-linked immunoassays. RESULTS: A PLS-SEM model revealed that Mexican American Hispanic pregnant women who were younger, single, lower income, more acculturated and who had greater negative coping, stress and depression were most at risk for having earlier and smaller babies.

An integrative review of maternal distress during neonatal intensive care hospitalization.

To synthesize literature addressing maternal distress and associated variables in response to infant hospitalization in the NICU. CINAHL, Medline, PubMed, PsychINFO, and Scopus were searched for studies addressing maternal distress during NICU hospitalization published between January 2009 and August 2019. The initial literature search yielded 862 articles. Articles were included for analysis if (a) they were peer-reviewed, (b) maternal distress was defined or measured, and (c) maternal distress occurred in the NICU. Ultimately, 33 articles were included for analysis. Distress symptoms were not consistently measured across the literature by one specific instrument. However, despite the variety of instruments, distress was prevalent in this population. Individual elements of maternal distress in the NICU include depression, anxiety, trauma, and post-traumatic stress symptoms. These elements often occur together and tend to follow a specific trajectory during hospitalization. This body of literature was inconsistent regarding the timing of distress measurement as well as the relationship between relevant associated variables (e.g., marital status or infant illness severity) and maternal distress. Additionally, researchers often excluded mothers of non-preterm infants and infants with congenital anomalies from investigation. Researchers and clinicians should carefully consider timing and instrumentation in their interpretations of maternal distress measurement during a NICU hospitalization. Future work should focus on developing a comprehensive, valid, and reliable screening tool for clinicians and researchers to use to identify maternal distress in the NICU. Additionally, future research should address gaps in the populations included in studies.

Oxidative Stress in Pregnant Women Between 12 and 20 Weeks of Gestation and Preterm Birth.

BACKGROUND: A known relationship exists between oxidative stress and preterm birth (PTB). However, few studies have measured oxidative stress prospectively in early or midpregnancy, and no studies have used electron paramagnetic resonance (EPR) spectroscopy prospectively to predict PTB. OBJECTIVE: The purpose of this study was to identify predictive relationships between antioxidants and reactive oxygen species (ROS), specifically, superoxide (O2), peroxynitrite (OONO), and hydroxyl radical (OH), using EPR spectroscopy, measured between 12 and 20 weeks of gestation and compare with the incidence of PTB. METHODS: Blood was obtained from pregnant women (n = 140) recruited from a tertiary perinatal center. Whole blood was analyzed directly for ROS, O2, OONO, and OH using EPR spectroscopy. Red blood cell lysate was used to measure antioxidants. PTB was defined as parturition at <37 weeks of gestation. RESULTS: No differences were found between ROS, O2, OONO, or OH with the incidence of PTB. Catalase activity, glutathione, and reduced/oxidized glutathione ratio were significantly lower with PTB. Logistic regression suggests decreased catalase activity in pregnant women is associated with increased odds of delivering prematurely. DISCUSSION: We prospectively compared antioxidants and specific ROS using EPR spectroscopy in pregnant women between 12 and 20 weeks of gestation with the incidence of PTB. Results are minimal but do suggest that antioxidants-specifically decreased catalase activity-in early pregnancy may be associated with PTB; however, these findings should be cautiously interpreted and may not have clinical significance.

Oxidative stress in early pregnancy and the risk of preeclampsia.

INTRODUCTION: Preeclampsia (PE), one of the most serious complications of pregnancy, is characterized by endothelial dysfunction and hypertension. The pathophysiology of the disease is still unknown; however, evidence suggests that placental and maternal oxidative stress promote the disease process. Several studies have assessed levels of oxidative stress during pregnancy, but after diagnosis of PE. However, few studies have examined oxidative stress before PE diagnosis. Thus, the present work was aimed to gain further insight into the role of oxidative stress prior to diagnosis of PE (i.e. 12-20 weeks of gestation) and to further understand and predict PE incidence. METHODS: Blood levels of superoxide (O2-) and erythrocyte antioxidants such as superoxide dismutase (SOD), catalase (CAT), reduced glutathione (GSH) and oxidized glutathione (GSSG) levels were measured in 23 preeclamptic pregnant women and 91 women with normal pregnancies. We further used logistic regression of O2- and each antioxidant level as the main predictor variable for PE risk. RESULTS: CAT activity, GSH, and Total glutathione (TGSH) were significantly lower with All PE pregnant groups, whereas O2- levels were modestly, but significantly, higher in women with mild PE. Logistic regression analysis suggests increased CAT activity in pregnant women is associated with a decreased odds of being preeclamptic. CONCLUSION: CAT is the only antioxidant as shown in our study to be related to the severity of the disease and may be a promising predictor for PE. Further studies are warranted to investigate the use of CAT as a novel therapeutic for PE.

Systematic Review: Feasibility, Reliability, and Validity of Maternal/Caregiver Attachment and Bonding Screening Tools for Clinical Use.

INTRODUCTION: Infant-caregiver attachment is crucial for an infant's immediate and long-term social-emotional development and health. Despite advocacy by the National Institute of Children's Health Quality for infant social-emotional development screening, there is a lack of identified tools for use in primary care. Therefore, we conducted a systematic review to identify caretaker-infant attachment self-report screening tools that would be feasible, reliable, and valid for use in primary care. METHOD: A systematic search identified 340 abstracts/articles, which were screened using inclusion and exclusion criteria. Twelve articles and six self-report attachment tools were examined for reliability, validity, and feasibility characteristics. RESULTS: Six caregiver-infant attachment self-report tools were identified. Establishment of feasibility, reliability, and validity are in the early stages. DISCUSSION: Potential infant-caretaker attachment screening tools were identified for use in primary care practices. Suggestions for research and practice include informal screening, additional psychometric testing, and development of policies supporting implementation of screening.

Oxidative Stress Levels Throughout Pregnancy, at Birth, and in the Neonate.

BACKGROUND: Oxidative stress is associated with poor perinatal outcomes. Little is known regarding the longitudinal levels of oxidative stress in the perinatal period or the correlation between maternal and neonatal oxidative stress levels. OBJECTIVE: Describe and compare oxidative stress, specifically superoxide, superoxide dismutase, catalase, and glutathione levels, over the perinatal period. STUDY DESIGN: Longitudinal descriptive design using a convenience sample of medically high- and low-risk pregnant women (n = 140) from a maternal-fetal medicine and general obstetrics practice, respectively. Blood was obtained from women at 12-20 and 24-28 weeks' gestation and during labor, from the umbilical cord at birth, and from neonates at 24-72 hr after birth. Levels of superoxide were measured using electron paramagnetic resonance (EPR) spectroscopy; antioxidants (superoxide dismutase, catalase, and glutathione) were measured using commercial assay kits. Relationships between oxidative stress levels at different time points were examined using nonparametric methods. Pregnancy outcome was collected. RESULTS: Demographic variables, outcome variables, and oxidative stress levels in maternal blood, cord blood, and infants differed between medically high- and low-risk women. Descriptive patterns for oxidative stress measures varied over time and between risk groups. Significant correlations between time points were noted, suggesting intraindividual consistency may exist throughout the perinatal period. However, these correlations were not consistent across each medical risk group. CONCLUSION: EPR spectroscopy is a feasible method for the perinatal population. Results provide new information on perinatal circulating superoxide levels and warrant further investigation into potential relationships between prenatal and neonatal physiologic dysregulation of oxidative stress.

Maternal Distress in the Neonatal Intensive Care Unit: A Concept Analysis.

BACKGROUND: The neonatal intensive care unit (NICU) can cause significant psychological distress in a mother. There is no common definition of maternal distress in the NICU currently in use. PURPOSE: To develop a clear conceptual understanding of maternal distress in the NICU using conceptual definitions and empirical findings. METHODS/SEARCH STRATEGY: A literature search was conducted using EBSCOhost, MEDLINE, CINAHL, PsychINFO, and Google Scholar. The concept analysis was guided by Walker and Avant's (2011) guide. FINDINGS/RESULTS: Maternal distress in the NICU consists of a combination of depressive, anxiety, trauma, and posttraumatic stress symptoms. The symptoms occur together on a spectrum and present differently in each mother. The antecedents to maternal distress are a NICU hospitalization and a perceived interruption to the transition to motherhood. Consequences of maternal distress in the NICU are issues with developing a healthy maternal-infant bond, adverse infant development, and decreased maternal quality of life. IMPLICATIONS FOR PRACTICE: A complete understanding of maternal distress in the NICU will lead to increased awareness of adverse mental health states in this population. IMPLICATIONS FOR RESEARCH: Identification of mothers at risk for maternal distress in the NICU, as well as the identification of antecedents and consequences related to the mother and the infant from maternal distress in the NICU. Using a single, clear definition of maternal distress in the NICU population will lead to a more cohesive body of literature.

Improving Staff Knowledge and Attitudes Toward Providing Psychosocial Support to NICU Parents Through an Online Education Course.

BACKGROUND: Provider-parent communication is a critical determinant of how neonatal intensive care unit (NICU) parents cope, yet staff feel inadequately trained in communication techniques; many parents are not satisfied with the support they receive from hospital providers. PURPOSE: This study evaluated whether NICU staff would demonstrate improved knowledge and attitudes about providing psychosocial support to parents after taking an online course. METHODS: After providing demographic information, staff at 2 NICUs took a 33-item survey both before and after taking a 7-module online course "Caring for Babies and Their Families," and again at 6-month follow-up. Scores (means ± standard deviation) from all time periods were compared and effect sizes calculated for each of the course modules. RESULTS: NICU staff participants (n = 114) included nurses (88%), social workers (7%), physicians (4%), and occupational therapists (1%). NICU staff showed significant improvement in both knowledge and attitudes in all modules after taking the course, and improvements in all module subscores remained significant at the 6-month follow-up mark. Night staff and staff with less experience had lower pretest scores on several items, which improved on posttest. IMPLICATIONS FOR PRACTICE: This course, developed by an interprofessional group that included graduate NICU parents, was highly effective in improving staff knowledge and attitudes regarding the provision of psychosocial support to NICU parents, and in eliminating differences related to shift worked and duration of work experience in the NICU. IMPLICATIONS FOR RESEARCH: Future research should evaluate course efficacy across NICU disciplines beyond nursing, impact on staff performance, and whether parent satisfaction with care is improved.

Interleukin-17A and Chronic Stress in Pregnant Women at 24-28 Weeks Gestation.

BACKGROUND: Allostatic load (AL) is a biopsychosocial model that suggests chronic psychosocial stress leads to physiological dysregulation and poor outcomes. The purpose of this study was to examine AL in pregnant women operationalized using proinflammatory cytokines and psychosocial indicators and perinatal outcomes. OBJECTIVES: The aim of the study was to identify relationships between circulating cytokines/chemokines and the Prenatal Distress Questionnaire, the Maternal Antenatal Attachment Scale, the Emotional Quotient Inventory, the Life Experiences Scale, and demographics in pregnant women. METHODS: A cross-sectional design was used to recruit pregnant women between 24 and 28 weeks of gestation. Blood and stress/emotional indicators were obtained after informed consent. Plasma was abstracted to simultaneously measure 29 cytokines/chemokines using a multiplex array. Cytokine/chemokine levels were compared with continuous variables using Spearman's rho and with categorical variables using Mann-Whitney U. RESULTS: Twenty-five women with medically high-risk (n = 16) and low-risk (n = 9) pregnancies consented. Most women were White (68%) with a mean age of 29 years (SD = 5.9). Although several cytokines and chemokines showed significant correlations with the stress/emotional indicators, only interleukin-17A (IL-17A) was significantly associated with all of the indicators (Prenatal Distress Questionnaire: rs = .528, p = .012; Maternal Antenatal Attachment Scale: rs = -.439, p = .036; Emotional Quotient Inventory total: rs = -.545, p = .007), Life Experiences Scale (rs = .458, p = .032), birth weight (rs = -.499, p = .013), and race (p = .01). DISCUSSION: Increased levels of IL-17A, a known cytokine associated with chronic stress and with poor perinatal outcomes, were associated with high prenatal distress, low maternal attachment, and lower emotional intelligence in pregnant women. Increased levels of IL-17A also were associated with lower birth weight and non-White race. Results support the model of AL in pregnant women and highlight IL-17A as a potential biomarker of AL during pregnancy.

Healthcare Workers Occupationally Exposed to Ionizing Radiation Exhibit Altered Levels of Inflammatory Cytokines and Redox Parameters.

Studies have shown an increased risk for a variety of cancers, specifically brain cancer, in healthcare workers occupationally exposed to ionizing radiation. Although the mechanisms mediating these phenomena are not fully understood, ionizing radiation-mediated elevated levels of reactive oxygen species (ROS), oxidative DNA damage, and immune modulation are likely involved. A group of 20 radiation exposed workers and 40 sex- and age-matched non-exposed control subjects were recruited for the study. We measured superoxide (O2•-) levels in whole blood of healthcare workers and all other measurements of cytokines, oxidative DNA damage, extracellular superoxide dismutase (EcSOD) activity and reduced/oxidized glutathione ratio (GSH/GSSG) in plasma. Levels of O2•- were significantly higher in radiation exposed workers compared to control. Similarly, a significant increase in the levels of interleukin (IL)-6, IL-1α and macrophage inflammatory protein (MIP)-1α in radiation exposed workers compared to control was observed, while there was no significance difference in the other 27 screened cytokines. A significant positive correlation was found between MIP-1α and O2•- levels with no correlation in either IL-6 or IL-1α. Further, a dose-dependent relationship with significant O2•- production and immune alterations in radiation exposed workers was demonstrated. There was no statistical difference between the groups in terms of oxidative DNA damage, GSH/GSSG levels, or EcSOD activity. Although the biologic significance of cytokines alterations in radiation exposed workers is unclear, further studies are needed for determining the underlying mechanism of their elevation.

Oxidative Stress and Preterm Birth: An Integrative Review.

BACKGROUND: A variety of methods and measures have been used to quantify oxidative stress in clinical studies related to preterm birth (PTB), and studies have reported conflicting findings. No integrative reviews have been conducted. OBJECTIVE: To describe specific molecules used as markers of oxidative stress and methods to measure these molecules and to review the literature for associations between oxidative stress and PTB specific to these molecules. METHOD: Systematic literature searches were conducted in June 2015 and updated in 2017 in databases from the Biomedical Reference Collection: Basic Edition, including MEDLINE and clinicaltrials.gov . Articles were included if they described original research published after 2009 and compared PTB or preterm premature rupture of membranes with term birth (TB). RESULTS: Abstracts ( n = 3,107) were reviewed for inclusion/exclusion criteria. Of these, 308 were full-text reviewed, and 30 articles were included in this review. All were identified as nonexperimental. The most common measurements of oxidative stress were quantification of total oxidant or antioxidant status or lipid peroxidation. Studies measuring reactive oxygen species or by-products of oxidative stress reported higher levels of these molecules for preterm specimens compared to TB specimens. Studies measuring antioxidants reported lower levels for these molecules in PTB specimens. Few of the studies had inconclusive findings. DISCUSSION: Findings suggest that an imbalance between oxidants and antioxidants may be associated with PTB. The measurements and findings to date limit interpretation and understanding. Research using multidimensional methods and multidisciplinary teams are necessary to advance research and practice.
