Family Management Skills Reported by Parents of Preterm Infants in the NICU Using the Self- and Family Management Framework (SFMF).

BACKGROUND: Across the globe, family-integrated care (FICare) has become an evidence-based standard in which parents deliver the majority of infant care in the neonatal intensive care unit (NICU). Because of extensive barriers to parent presence, adaptations to FICare may be required for successful implementation. Family management theory may provide structure to the Parent Education of FICare and help nurses guide parents' skill development as equal care members. PURPOSE: To identify family management skills employed by NICU parents using the Self- and Family Management Framework (SFMF). METHODS: We conducted secondary analyses of qualitative interview data from NICU parents (n = 17) who shared their experiences of using family management skills to care for their infant. We categorized skills according to 3 main self- and family management processes: Focusing on Infant Illness Needs; Activating Resources; and Living With Infant Illness. RESULTS: Parents reported several family management skills currently identified in the SFMF, as well as new skills such as conflict management, power brokerage, and addressing resources related to social determinants of health. Parent activation of resources was critical to sustaining parent focus on the infant's illness needs. IMPLICATIONS FOR PRACTICE AND RESEARCH: By teaching skills that parents reported as helping them manage infant care, neonatal nurses may better facilitate parent integration into the care team. Future researchers can incorporate the skills identified in this study into the design of family management interventions that facilitate FICare implementation in the United States.

National Norms for Hospitalizations Due to Ambulatory Care Sensitive Conditions among Adults in the US.

BACKGROUND: Ambulatory care sensitive conditions (ACSCs) are acute or chronic health issues that lead to potentially preventable hospitalizations when not treated in the outpatient primary care setting. OBJECTIVE: To describe national hospitalization rates due to ACSCs among adult inpatients in the US. DESIGN: A retrospective cross-sectional analysis of the 2018 US National Inpatient Sample (NIS) dataset from the Healthcare Cost and Utilization Project at the Agency of Healthcare Research and Quality was completed in the year 2022. PARTICIPANTS: Participants were adult inpatients from community hospitals in 48 states of the US and District of Columbia. MAIN MEASURES: ACSC admission rates were calculated using ICD-10 codes and the Purdy ACSC definition. The admission rates were weighted to the US inpatient population and stratified by age, sex, and race. KEY RESULTS: ACSC hospitalization rates varied considerably across age and average number of hospitalizations varied across sex and race. ACSC hospitalization rates increased with age, male sex, and Native American and Black race. The most common ACSCs were pneumonia, diabetes, and congestive heart failure. CONCLUSIONS: Previous studies have emphasized the importance of preventable hospitalizations, however, the national rates for ACSC hospitalizations across all ages in the US have not been reported. The national rates presented will facilitate comparisons to identify hospitals and health care systems with higher-than-expected rates of ACSC admissions that may suggest a need for improved primary care services.

Encouraging Our NICU to "Read-a-Latte": Leveraging a Read-a-Thon to Launch a Quality Improvement Initiative.

BACKGROUND: Preterm infants have known impairments in language development relative to infants born at full term, and the language-poor environment of the neonatal intensive care unit (NICU) is a contributing factor. Adapting outpatient literacy programs for the NICU is a potential evidence-based intervention to encourage adult speech exposure to infants through reading sessions during NICU hospitalization. PURPOSE: To evaluate implementation of a 10-day NICU Read-a-Thon and potential barriers and facilitators of a year-round program aimed at increasing reading sessions for NICU patients. METHODS: We established an implementation team to execute a Read-a-Thon and evaluated its impact utilizing quantitative and qualitative approaches. Quantitative methodology was used to report number of donated books and infant reading sessions. Qualitative methodology inclusive of interviews, surveys, and source document reviews was used to evaluate the Read-a-Thon. RESULTS: We received approximately 1300 donated books and logged 663 reading sessions over the 10-day Read-a-Thon. Qualitative evaluation of the Read-a-Thon identified 6 main themes: motivation, emotional response to the program, benefits and outcomes, barriers, facilitators, and future of literacy promotion in our NICU. Our evaluation informed specific aims for improvement (eg, maintaining book accessibility) for a quality improvement initiative to sustain a year-round reading program. IMPLICATIONS FOR PRACTICE AND RESEARCH: Neonatal units can leverage Read-a-Thons as small tests of change to evaluate barriers, facilitators, and change processes needed to implement reading programs. Process maps of book inventory and conducting a 5 W's, 2 H's (who, what, when, where, why, how, how much) assessment can aid in program planning.

Application of a Risk Management Framework to Parent Sleep During Skin-to-Skin Care in the NICU.

As NICU staff work to increase the frequency, duration, and comfort of skin-to-skin care (SSC) sessions, barriers to implementation are frequently encountered. Safety concerns are often raised when parents fall asleep during SSC intentionally or unintentionally. We present a risk management framework that we use in clinical practice to address risk related to parent sleep during SSC. Our approach is based on the steps of the Risk Management Life Cycle, which include the following: establish context, identify risk, analyze risk, respond to risk, and monitor and adapt response to risk. Clinicians may use this framework in clinical practice to manage risks related to prolonged SSC, specifically when parents relax and fall asleep during SSC.

Realigning Expectations With Reality: A Case Study on Maternal Mental Health During a Difficult Breastfeeding Journey.

INTRODUCTION: Many mothers have the goal to breastfeed. However, more than 50% will have breastfeeding difficulty by the 3rd day of life. Mothers who are unable to meet their breastfeeding goals are at higher risk for anxiety, depression, embarrassment, and guilt. Those who stop breastfeeding need support and help resolving these feelings. This case study aims to describe one woman's difficulty with mental health surrounding breastfeeding, her decision to bottle feed, and her successful transition back to direct breastfeeding. MAIN ISSUE: Barriers to the participant's success with breastfeeding were pre-existing history of depression/anxiety, forceps delivery, uncontrolled perineal pain, infant physical trauma, and nipple/flow confusion. The decision to discontinue direct breastfeeding and start bottle feeding came after 2 months of anxiety, frustration, and persistence. MANAGEMENT: The participant followed her healthcare team's recommendations of triple feeding, lactation support groups, pediatric chiropractic adjustments, and prescribed galactagogues. After 2 months of exhaustion and deliberation, she made the difficult decision to stop breastfeeding for nutritional benefits and switched to breastfeeding only for her infant's pleasure and comfort. Lowered expectations allowed the dyad to heal and her son to transition to nearly exclusive breastfeeding at 4 months of life. CONCLUSION: Clinicians must be aware of the delicate balance between promoting breastfeeding for its nutritional value and health benefits and supporting a struggling mother with mental health needs.

Neonatal Nurses' Report of Family-Centered Care Resources and Practices.

BACKGROUND: A paucity of studies describes the prevalence of family-centered care (FCC) practices and resources in US neonatal units. PURPOSE: To identify US prevalence of FCC practices and resources and to identify the largest gaps in resource provision. METHODS: Neonatal nurses completed an online survey through national conferences (eg, NANN educational conference), neonatal organization Web sites (eg, NANN research survey), and social media (eg, NANN and NPA Facebook). Nurses provided demographics and the National Perinatal Association Self-Assessment on Comprehensive Family Support, a 61-item checklist of FCC practices and resources from 6 categories: family-centered developmental care, staff education/support, peer support, palliative care, discharge education, and mental health support. RESULTS: Nurses (n = 103) reported lowest resources for Peer Support and Mental Health Support. About a third had a neonatal intensive care unit parent advisory committee (n = 39; 37.9%). Only 43.7% (n = 45) had necessary amenities for families to stay with their infants. Less than a third felt that mental health professionals were adequately staffed to provide counseling to parents (n = 28; 27.5%). Very few nurses had adequate training on providing parents psychological support (n = 16; 15.8%). More than half (n = 58; 56.3%) stated that all staff receive training in family-centered developmental care. Finally, less than half (n = 42; 40.8%) stated that staff see parents as equal members of the care team. IMPLICATIONS FOR PRACTICE: We demonstrate a consistent and widespread lack of training provided to neonatal staff in nearly every aspect of comprehensive FCC support. IMPLICATIONS FOR RESEARCH: Researchers need to identify unit/organizational interventions that increase adoption and implementation of FCC practices and resources.

A clinical-academic partnership to develop a family management intervention for parents of preterm infants.

AIMS: To examine the critical role that an academic clinical partnership played in the development and refinement of a family management intervention in the Neonatal Intensive Care Unit (NICU). BACKGROUND: Clinical-academic partnerships enable earlier infusion of implementation science principles into development of evidence-based interventions, yet partners often report difficulty leveraging resources, personnel and expertise to create beneficial outcomes for all. DESIGN: Longitudinal qualitative descriptive design. METHODS: To develop and refine the intervention, designated time was taken during meetings of the NICU's Parent Partnership Council (PPC), a committee comprised of nursing, physician and allied health leadership and former NICU parents. Partnership was also achieved by having bedside clinical nurses, in addition to medical and nursing students, participate as research team members. Qualitative data were collected via email, research team and Council meetings, and informal individual chats with key stakeholders (N = 25) and NICU mothers (N = 22). Qualitative data were analysed deductively using thematic analysis based on MacPhee's partnership logic model and the Reach, Effectiveness, Adoption, Implementation and Maintenance (RE-AIM) model. The consolidated criteria for reporting qualitative research checklist guided our work. RESULTS: During Council meetings, the clinical-academic nurse, Director of Family-Integrated Care and Council members identified the need for a family management intervention, and worked together to develop and refine PREEMIE PROGRESS. Mothers found the intervention had numerous strengths and perceived a benefit knowing they helped future parents. CONCLUSIONS: This work was only possible by leveraging both the university's technology/research resources and the clinical expertise of the NICU staff and PPC. Co-authored presentations, publications and grant funding continued this NICU's legacy in family-centred care and helped shape the clinical-academic nurse's career. RELEVANCE TO CLINICAL PRACTICE: Clinical-academic partnerships can promote excellence in nursing practice, research and education through swifter knowledge translation and earlier infusion of implementation science principles into the development of evidence-based nursing interventions.

Elucidating the context for implementing nonpharmacologic care for neonatal opioid withdrawal syndrome: a qualitative study of perinatal nurses.

BACKGROUND: Up to 95% of neonates exposed to opioids in utero experience neonatal opioid withdrawal syndrome at birth. Nonpharmacologic approaches (e.g., breastfeeding; rooming-in; skin-to-skin care) are evidence-based and should be implemented. These approaches, especially breastfeeding, rely on engagement of the neonates' mothers to help deliver them. However, little is known about the structural and social dynamic context barriers and facilitators to implementing maternal-delivered nonpharmacologic care. METHODS: Using a qualitative descriptive design, perinatal nurses from a Midwest United States hospital family birthing center, neonatal intensive care unit, and inpatient pediatric unit were interviewed. These units were involved in caring for mothers and neonates affected by opioid use. Telephone interviews followed a semi-structured interview guide developed for this study, were audio-recorded, and lasted about 30-60 min. Interviews were transcribed verbatim and independently analyzed by five investigators using the constant comparative method. Themes were discussed until reaching consensus and subsequently mapped to a conceptual model adapted for this study. RESULTS: Twenty-one nurses participated in this study (family birth center, n = 9; neonatal intensive care, n = 6; pediatrics, n = 6). Analysis resulted in four major themes: 1) Lack of education and resources provided to staff and mothers; 2) Importance of interdisciplinary and intradisciplinary care coordination; 3) Flexibility in nurse staffing models for neonatal opioid withdrawal syndrome; and 4) Unit architecture and layout affects maternal involvement. Minor themes supported each of the four major themes. All themes mapped to the conceptual model. CONCLUSIONS: This study provides a more comprehensive understanding of the barriers and facilitators affecting implementation of maternal involvement in nonpharmacologic care of newborns with neonatal opioid withdrawal syndrome. Future efforts implementing nonpharmacologic approaches must consider the context factors affecting implementation, including structural and social factors within the units, hospital, and broader community.

Early antenatal counseling in the outpatient setting for high-risk pregnancies: a randomized control trial.

OBJECTIVES: Determine if antenatal counseling delivered in the outpatient setting improves parental knowledge and satisfaction without contributing to anxiety. STUDY DESIGN: Randomized control trial at a large academic institution. Mothers at risk for preterm delivery were enrolled following routine maternal-fetal medicine (MFM) visits and randomized to early antenatal counseling of prematurity or standard counseling by MFM providers. The primary outcome was parental knowledge of prematurity. Secondary outcomes included parental satisfaction, anxiety scores, and compliance with recommended follow-up. RESULTS: Seventy-six women were enrolled, 38 in each group. Early counseling group had higher knowledge scores (86.3 vs 64.3, p = <0.001) and parental satisfaction (p = 0.003). Anxiety scores were similar between the two groups (38.2 vs 40.4, p = 0.53). No difference was noted in compliance with follow-up. CONCLUSIONS: Antenatal counseling in the high-risk outpatient setting improved parental knowledge and satisfaction without leading to increased anxiety.

A Survey of Neonatal Clinicians' Use, Needs, and Preferences for Kangaroo Care Devices.

BACKGROUND: Decades of research supports the benefits of kangaroo care (KC) for the parent and newborn. Supportive KC devices may be an important tool clinicians can use to assist parents with KC. In recent years, there has been a rise in the availability of KC devices. However, the use, needs, and preferences for these supportive devices by neonatal clinicians have not been documented. PURPOSE: To survey clinicians' use, needs, and preferences of KC supportive devices, and examine whether differences exist based on clinician and organizational characteristics. METHODS: A cross-sectional, online survey was sent through neonatal organization Web sites, conferences, and social media. RESULTS: Many clinicians (n = 68, 43%; N = 158) facilitated KC with a supportive device, with 81% of devices provided by the clinician's employer. The most important "Must Have" feature of a KC device was "Safety: Reduces patient falls if caregiver sleeps or needs to use hands" (84% of respondents) followed by washability (82%), and "immediate, effective access to the baby" (78%). Clinicians' responses did not differ based on hospital setting, type of unit, KC experience, or experience using a KC device. IMPLICATIONS FOR PRACTICE: To support safe use of KC devices in neonatal intensive care unit (NICU) clinical care, a device must hold the proper KC position consistently, allow immediate access to the infant, and hold the infant in place without the parent's hands to prevent falls. Training is needed to ensure safe device use. IMPLICATIONS FOR RESEARCH: Future research should evaluate the safety, efficacy, and cost-effectiveness of these devices.

Engaging Mothers to Implement Nonpharmacological Care for Infants With Neonatal Abstinence Syndrome: Perceptions of Perinatal and Pediatric Nurses.

BACKGROUND: Little is known about nurse perceptions regarding engagement of mothers in implementation of nonpharmacological care for opioid-exposed infants. PURPOSE: This study was designed to describe perinatal and pediatric nurse perceptions of (1) engaging mothers in the care of opioid-exposed infants and (2) facilitators and barriers to maternal engagement. METHODS: This study used a qualitative descriptive design to interview perinatal and pediatric nurses in one Midwest United States hospital. Interviews were conducted via telephone using a semistructured interview guide and audio recorded. Audio files were transcribed verbatim and thematically analyzed using the constant comparative method. RESULTS: Twenty-one nurses participated in the study, representing a family birth center, neonatal intensive care unit, and pediatric unit. Five major themes resulted from analysis: (1) vulnerability and bias; (2) mother-infant care: tasks versus model of care; (3) maternal factors affecting engagement and implementation; (4) nurse factors affecting engagement and implementation; and (5) recommendations and examples of nursing approaches to barriers. Minor themes supported each of the major themes. IMPLICATIONS FOR PRACTICE: Nurses must engage mothers with substance use histories with empathy and nonjudgment, identify and promote maternal agency to care for their infants, and engage and activate mothers to deliver nonpharmacological care during the hospital stay and following discharge. IMPLICATIONS FOR RESEARCH: Findings suggest interventions are needed to improve (1) nursing education regarding maternal substance use and recovery, (2) empathy for substance-using mothers and mothers in treatment, and (3) identification and support of maternal agency to provide nonpharmacological care to withdrawing infants.

Clinician Opinions and Approaches to Manage Risk Related to Safe Sleep During Skin-to-Skin Care.

OBJECTIVE: To understand the opinions of clinicians about the risks, benefits, barriers, and facilitators to the practice of parent sleep during skin-to-skin care in hospital settings. DESIGN: Cross-sectional survey. SETTING: Online survey. PARTICIPANTS: Clinicians who self-identified as infant care providers, that is, neonatal clinicians (N = 158). METHODS: We sent an online survey invitation to neonatal clinicians through neonatal websites, conferences, and social media sites in the United States and used snowball recruitment. We used a risk management framework to analyze qualitative data. We used descriptive statistics and the chi-square and Fisher's exact tests to determine if opinions differed based on clinician and organizational characteristics. RESULTS: Respondents' support of parent sleep during skin-to-skin care (yes/no) did not differ on the basis of whether the clinician had taken a formal course on skin-to-skin care, facilitated skin-to-skin care more than 100 times, or frequently promoted skin-to-skin care in current practice. Respondents who supported parent sleep (n = 93, 59% of respondents) reported greater implementation of risk control strategies than nonsupporters (n = 53 [57%] vs. n = 3 [5%]; p < .001), such as frequent monitoring of vital signs (n = 33 [35%] vs. n = 2 [3%]; p < .001), use of devices to support skin-to-skin care (n = 49 [53%] vs. n = 19 [29%]; p = .003), and proper positioning (n = 20 [22%] vs. n = 0 [0%]; p < .001). Nonsupporters more frequently reported that parent sleep during skin-to-skin care violates safe sleep recommendations, is habit forming for home, poses a fall risk, and jeopardizes the infant's airway. CONCLUSION: Most respondents supported parent sleep during skin-to-skin care, but concerns regarding safety for the infant remained a barrier. The use of a risk management framework may help facilitate a systematic approach to improve the implementation of safe skin-to-skin practices.

Reducing toxic stress in the neonatal intensive care unit to improve infant outcomes.

In 2011, the American Academy of Pediatrics (AAP) published a technical report on the lifelong effects of early toxic stress on human development, and included a new framework for promoting pediatric health: the Ecobiodevelopmental Framework for Early Childhood Policies and Programs. We believe that hospitalization is a specific form of toxic stress for the neonatal patient, and that toxic stress must be addressed by the nursing profession in order to substantially improve outcomes for the critically ill neonate. Approximately 4% of normal birthweight newborns and 85% of low birthweight newborns are hospitalized each year in the highly technological neonatal intensive care unit (NICU). Neonates are exposed to roughly 70 stressful procedures a day during hospitalization, which can permanently and negatively alter the infant's developing brain. Neurologic deficits can be partly attributed to the frequent, toxic, and cumulative exposure to stressors during NICU hospitalization. However, the AAP report does not provide specific action steps necessary to address toxic stress in the NICU and realize the new vision for pediatric health care outlined therein. Therefore, this paper applies the concepts and vision laid out in the AAP report to the care of the hospitalized neonate and provides action steps for true transformative change in neonatal intensive care. We review how the environment of the NICU is a significant source of toxic stress for hospitalized infants. We provide recommendations for caregiving practices that could significantly buffer the toxic stress experienced by hospitalized infants. We also identify areas of research inquiry that are needed to address gaps in nursing knowledge and to propel nursing science forward. Finally, we advocate for several public policies that are not fully addressed in the AAP technical report, but are vital to the health and development of all newborns.

Paid Family Leave to Enhance the Health Outcomes of Preterm Infants.

Prematurity is the largest contributor to perinatal morbidity and mortality. Preterm infants and their families are a significant vulnerable population burdened with limited resources, numerous health risks, and poor health outcomes. The social determinants of health greatly shape the economic and psychosocial resources that families possess to promote optimal outcomes for their preterm infants. The purposes of this article are to analyze the resource availability, relative risks, and health outcomes of preterm infants and their families and to discuss why universal paid family leave could be one potential public policy that would promote optimal outcomes for this infant population. First, we discuss the history of family leave in the United States and draw comparisons with other countries around the world. We use the vulnerable populations conceptual model as a framework to discuss why universal paid family leave is needed and to review how disparities in resource availability are driving the health status of preterm infants. We conclude with implications for research, nursing practice, and public policy. Although health care providers, policy makers, and other key stakeholders have paid considerable attention to and allocated resources for preventing and treating prematurity, this attention is geared toward individual-based health strategies for promoting preconception health, preventing a preterm birth, and improving individual infant outcomes. Our view is that public policies addressing the social determinants of health (e.g., universal paid family leave) would have a much greater impact on the health outcomes of preterm infants and their families than current strategies.

Expanding Regulation Theory With Oxytocin: A Psychoneurobiological Model for Infant Development.

BACKGROUND: Oxytocin (OT), an affiliation hormone released during supportive social interactions, provides an exemplar of how social environments are reflected in our neurobiology from the beginning of life. A growing body of OT research has uncovered previously unknown functions of OT, including modulation of parenting behaviors, neuroprotection, affiliation, and bonding. Regulation theory provides a strong framework for describing how the maternal care environment affects infant neurodevelopment through a symphony of molecules that form the neurobiological milieu of the developing infant brain. OBJECTIVES: The purpose of this article was to expand on regulation theory by discussing how OT-based processes contribute to infant neurobiology and by proposing a new model for maternal-infant nursing practice and research. APPROACH: We structure our discussion of the socially based, neurobiological processes of OT through its effects in the nested hierarchies of genetic, epigenetic, molecular, cellular, neural circuit, multiorgan, and behavioral levels. Our discussion is also presented chronologically, as OT works through a positive feedback loop during infant neurodevelopment, beginning prenatally and continuing after birth. IMPLICATIONS: Nurses are in a unique position to use innovative discoveries made by the biologic sciences to generate new nursing theories that inform clinical practice and inspire the development of innovative interventions that maximize the infant's exposure to supportive maternal care.

Associations Between Nurse-Guided Variables and Plasma Oxytocin Trajectories in Premature Infants During Initial Hospitalization.

BACKGROUND: Oxytocin (OT) is a social hormone that may help researchers understand how nurse-guided interventions during initial infant hospitalization, such as supporting human milk expression, promoting comforting touch, and reducing exposure to stressors, affect preterm brain development. PURPOSE: To determine whether factors related to human milk, touch, or stressor exposure are related to plasma OT trajectories in premature infants. METHODS: Plasma from 33 premature infants, born gestational ages 25 to (Equation is included in full-text article.)weeks, was collected at 14 days of life and then weekly until 34 weeks' corrected gestational age (CGA). Variables related to feeding volumes of human milk and formula; touch, as indexed by skin-to-skin contact (SSC) and swaddled holding; and clinical stressors were extracted from the electronic medical record. Linear mixed-models tested associations between nurse-guided variables and plasma OT trajectories. RESULTS: In the final model, same-day SSC was positively related not only to plasma OT levels at 27 weeks' CGA (ß= .938, P = .002) but also to a decline in plasma OT levels over time (ß=-.177, P = .001). Volume of enteral feeds (mL/kg/d), its interaction with CGA, and number of stressful procedures were not statistically significant (ß= .011, P = .077; ß=-.002, P = .066; and ß= .007, P = .062, respectively). IMPLICATIONS FOR PRACTICE: Nurse-guided interventions are associated with infant plasma OT levels, suggesting nurses may impact the neurobiology of the developing premature infant. IMPLICATIONS FOR RESEARCH: Replication with larger sample sizes and randomized controlled trial designs is needed to test effects of specific nursing interventions on infant OT.

Plasma and Urinary Oxytocin Trajectories in Extremely Premature Infants During NICU Hospitalization.

Extremely premature infants are at great risk for poor neurodevelopmental outcomes, in part because neurologic structures designed to mature in the womb must now do so in the extrauterine environment. Reliable biomarkers of neurodevelopment are especially critical in this population, as behavioral measures can be unreliable due to immaturity of the premature infant nervous system. Oxytocin (OT) has the potential to be a marker of neurobiological processes that offer infant neuroprotection. However, no studies have measured OT in the plasma and urine of premature infants. The purposes of this study were to describe plasma and urine OT levels of premature infants through 34 weeks corrected gestational age (CGA), determine whether plasma and urine OT are correlated, and explore associations between infant demographics and OT trajectories. Plasma and urine from 37 premature infants, born at gestational ages 25-28 6/7 weeks, were longitudinally collected at 14 days of life, then weekly until 34 weeks CGA. Plasma OT decreased with age, at a rate of 15% per week, and exhibited strong stability within infants. Urine OT was not correlated with plasma OT and did not show a significant trend over time; thus, urine may not be a reliable, noninvasive measurement in this population. Apgar score was the only infant demographic characteristic associated with plasma OT. Given the novelty of this work, replication is needed to confirm these findings, and future research should explore potential mechanisms (e.g., stress, normal maturation, and social experiences) that contribute to declining plasma OT levels in premature infants.

Insomnia and Relationship With Immunosuppressant Therapy After Lung Transplantation.

BACKGROUND: Lung transplant recipients are at high risk of developing sleep disorders such as insomnia, but the prevalence and features are currently poorly characterized within this population. Since these disorders are associated with increased morbidity and mortality, it is important to identify them to optimize the care of lung transplant recipients. We sought to evaluate the prevalence of insomnia within our university-based lung transplant clinic and determine whether a relationship exists between insomnia and exposure to immunosuppressant medications following transplantation. METHODS: Participants were recruited through the University of Wisconsin Hospital and Clinics Lung Transplant Clinic (N = 125). Participants (n = 92) completed the adult sleep history questionnaire, which included the Insomnia Severity Index (ISI) to assess for insomnia (defined as ISI score >10). Cumulative tacrolimus exposure was determined in 73 patients by performing an area under the curve calculation to assess for a potential relationship between tacrolimus exposure and insomnia. RESULTS: The prevalence of insomnia was 40% within this population. Although no difference in time since transplant was found, cumulative mean ± standard error of the mean tacrolimus exposure was significantly higher in patients with insomnia versus those without insomnia (17 190 ± 1673 ng·d/mL vs 12 130 ± 1630 ng·d/mL, respectively; P = .04). Estimated tacrolimus exposure was not greater with increasing frequency of insomnia complaints (analysis of variance P = .54). CONCLUSION: In our population, insomnia is common after lung transplantation, with prevalence greater than the general population. Higher cumulative exposure to tacrolimus may contribute to insomnia in this group. Future research should investigate the relationship between immunosuppressant therapy and development of sleep disorders.

Oxytocin trajectories and social engagement in extremely premature infants during NICU hospitalization.

Extremely premature infants, born 28 weeks gestation or less, are at high risk for impaired socioemotional development, due in part to exposure to early stressful social experiences that alter brain development. Understanding mediators that link experience with outcomes is necessary to assess premature infant responses to social experiences that are critical to brain development. The hormone oxytocin (OT), released during supportive interactions, has potential as a biomarker of the premature infant's responses to social experiences. The purpose of this study was to examine associations among infant plasma OT trajectories and maternal-infant social engagement behaviors during initial hospitalization. This study also examined demographic correlates of engagement behaviors in mothers and infants. Plasma from 28 extremely premature infants, born gestational ages 25-28 6/7 weeks, was collected at 14 days of life, then weekly until 34 weeks. Social engagement behaviors were measured by the Parent-Child Early Relational Assessment during a videotaped feeding when the infant was receiving one-quarter full oral feeds. Maternal-infant demographics were extracted from the medical record. Higher infant plasma OT was associated with lower infant social engagement, but no associations were found with maternal social engagement. Infant social engagement was positively related to maternal social engagement. Maternal parity was related to maternal social engagement, and infant demographics did not predict infant social engagement. The significant, yet negative, association between infant OT and engagement provides support for the measurement of OT as a neurobiological antecedent to infant social behaviors. Finally, this research suggests that during the earliest period of infant socio-behavioral development, premature infants are behaviorally reactive to the social engagement behaviors of their mothers.

Phylogenetic ANCOVA: Estimating Changes in Evolutionary Rates as Well as Relationships between Traits.

We present a new phylogenetic comparative method-phylogenetic analysis of covariance (PANCOVA)-that uses interspecific data and a phylogeny to estimate the effects of major events on both the rate of phenotypic evolution and the association between traits. It could be used, for example, to model the impact of a key innovation, colonization of a new habitat, or environmental change. The approach is optimized with maximum likelihood and is formulated under the familiar phylogenetic generalized least squares framework, which is flexible and easily extended to incorporate other factors and parameters. As an example, we explore the relationship between parental investment and relative telencephalon size in birds and contrast the results of PANCOVA with those from other phylogenetic comparative methods.
