ABSTRACT

OBJECTIVES: Research on Black maternal populations often focuses on deficits that can reinforce biases against Black individuals and communities. The research landscape must shift towards a strengths-based approach focused on the protective assets of Black individuals and communities to counteract bias. This study engaged the local Black community using a strengths-based approach to discuss the assets of Black maternal populations and to inform the design of a future clinical trial focused on reducing Black maternal health disparities. DESIGN: Guided by the Theory of Maternal Adaptive Capacity, we conducted three purposive focus group sessions with Black adult community members. The focus groups were semi-structured to cover specific topics, including the strengths of the local community, strengths specific to pregnant community members, how the strengths of community members can support pregnant individuals, and how the strengths of pregnant community members can facilitate a healthy pregnancy. The focus group interviews were transcribed verbatim and analyzed using thematic content analysis. RESULTS: Three focus group sessions were conducted with sixteen female individuals identifying as Black or African American. Central themes include (1) the power of pregnancy and motherhood in Black women, (2) challenging negative perceptions and media representation of Black mothers, (3) recognizing history and reclaiming cultural traditions surrounding birth, and (4) community as the foundation of Black motherhood. CONCLUSION: Black community members identified powerful themes on Black maternal health through a strengths-based lens. These focus groups fostered relationships with the Black community, elucidated possible solutions to improve Black women's health and wellness, and offered direction on our research design and intervention.

ABSTRACT

BACKGROUND: Neonatal care has advanced significantly in recent years, yet racial health inequities persist in the neonatal intensive care unit (NICU), with infants from racial and ethnic minority groups less likely to receive recommended treatment. Healthcare providers acknowledge that there are steps that can be taken to increase knowledge and awareness regarding health inequities. PURPOSE: To better understand current health equity-related initiatives in the neonatal community and solicit feedback from National Association of Neonatal Nurses (NANN) membership about advancing racial equity within the organization. METHODS: A cross-sectional survey was conducted in January 2021. The anonymous, onetime survey was distributed to active NANN members via SurveyMonkey and included questions related to racial equity initiatives, recommendations, and demographics. Data analysis was conducted using an exploratory approach using descriptive statistics, and thematic analysis was used to summarize responses to open-ended questions. RESULTS: There were 325 members who completed the full survey, of whom were White (83%), female (96%), staff nurses (42%), and those with more than 16 years of experience (69%), and most (69%) were familiar with NANN's racial equity position statement. Recommendations were summarized into the following themes: (1) research, (2) education, (3) workforce diversity, (4) communication, (5) scholarships, (6) resources, and (7) community outreach. IMPLICATIONS FOR PRACTICE AND RESEARCH: NANN members offered clear and actionable recommendations to advance health equity within the neonatal community and organization, which included offering more diversity, inclusion, and equity education at the annual conferences, in ANC articles, and newsletters, and the creation of scholarships or reduced membership fees to encourage diverse enrollment in the organization.

ABSTRACT

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.

ABSTRACT

BACKGROUND: Pathologic changes in the microbiome (dysbiosis) have been implicated in affecting the growth and neurodevelopment of infants and children. There is evidence to suggest that prenatal and postnatal stressors may be a factor in dysbiosis and there is also a growing body of evidence to suggest that interventions may reduce this negative impact. A scoping review was undertaken to identify association between maternal and/or child microbiome with child growth and neurodevelopment. Additionally, intervention studies such as use of nutritional supplementation and its impact on the microbiome, growth and neurodevelopment were reviewed. METHODS: An exhaustive literature search identified 654 relevant citations. After review of abstracts, 557 were eliminated, and 97 remained for full text review. We identified and reported on 42 articles which met inclusion criteria. RESULTS: Seven studies examined associations between microbiome and neurodevelopment and 36 studies evaluated anthropometric measurements, most commonly weight, and microbiota relationships. One study evaluated both growth and neurodevelopment and microbiota. Fourteen studies evaluated supplemental nutrients. Preterm, low birth weight (LBW), and very low birth weight (VLBW) infants were most studied. Findings were inconclusive for consistent associations between microbiota and growth and neurodevelopment. Further, there were no consistent conclusive changes with prescribed treatment interventions. DISCUSSION: There is a need for high-quality longitudinal studies evaluating repeated developmental assessment measures using consistent microbial analysis techniques to inform conclusions regarding the association between microbiome and infant and child growth and neurodevelopment. Additional intervention studies that may mitigate dysbiosis are warranted.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

OBJECTIVES: The COVID-19 pandemic has caused considerable stress throughout the world. Little is known about how postpartum women who gave birth during the early months of the pandemic were impacted. The purpose of this study was to explore and describe the associations between potential risk, protective factors, and psychological distress among postpartum women who gave birth during the early months of the COVID-19 pandemic. METHODS: Postpartum women over the age of 18 years who gave birth in the US hospitals between March and July of 2020 and spoke English completed a survey about their experiences. Demographic and health variables were measured via self-report. Stress was measured using the Perceived Stress Scale-10. Mastery was measured with the Pearlin Mastery Scale. Resilience was measured with the Connor-Davidson Resilience Scale-2. RESULTS: This study included 885 women. Participants had higher stress and lower resilience relative to pre-pandemic norms. Participants had high levels of depression, anxiety, and stress. Women who had an infant admitted to the neonatal intensive care unit had more stress. Income, full-time employment, and partnered relationships were associated with lower stress. Resilience and mastery were related to lower stress, depression, and anxiety. Black, Indigenous, or People of Color women showed higher stress and lower resiliency. Single women were likely to report lower levels of mastery than partnered women. CONCLUSION: Stress, depression, and anxiety were high in postpartum women in this study. Income, partnered relationships, and employment security, along with protective traits such as mastery and resilience, may reduce the impact of stress on postpartum women in a pandemic. Care models should be modified to support women during a pandemic. Health disparities exist in postpartum stress. Future interventions should focus on building resiliency and mastery and ensuring appropriate resources are available to postpartum women in a pandemic.

ABSTRACT

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..

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

BACKGROUND: Rapid screening for tuberculosis (TB) disease at intake into immigrant detention facilities allows for early detection and treatment. Detention facilities with United States Immigration and Customs Enforcement (ICE) Health Service Corps (IHSC) medical staffing utilize chest radiography and symptom screening as the primary screening for pulmonary TB (PTB) disease. This analysis describes the demographic, clinical, and microbiological characteristics of individuals identified with TB disease at these facilities. METHODS: We conducted a retrospective analysis to describe the population of immigrant detainees identified via chest radiography with PTB disease between 1 January 2014 and 31 December 2016 at facilities with IHSC medical staffing. We collected demographic variables, clinical presentation, diagnostic testing results, and microbiological findings. We generated descriptive statistics and examined univariate and multivariate associations between the variables collected and symptomatic status. RESULTS: We identified 327 patients with confirmed PTB disease (incidence rate, 92.8 per 100 000); the majority of patients were asymptomatic (79.2%) at diagnosis. Adjusting for all other variables in the model, the presence of cavitary lesions, acid-fast bacillus smear positivity, and multilobar presentation were significantly associated with symptomatic status. Among all patients identified with TB disease who had a tuberculin skin test (TST) result recorded, 27.2% were both asymptomatic and TST negative, including those with smear-positive disease. CONCLUSIONS: Asymptomatic PTB disease is a significant clinical entity among immigrant detainees and placement in a congregate setting calls for aggressive screening to prevent transmission. Early identification, isolation, and treatment of TB disease benefit not only the health of the patient, but also the surrounding community.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.
