RESUMEN

BACKGROUND: Recruitment and retention of diverse faculty in schools of nursing continues to be an important challenge but little has been written from the perspectives of early-career faculty of color on their decision to join academia and their retention. PURPOSE: We aim to understand the perspectives of a cluster hire of early-career faculty of color on their recruitment, mentorship and support received, and resources needed for long-term retention. METHODS: Five faculty members conducted a joint autoethnography of their perspectives through recruitment, hiring, and first year as faculty. Two group discussions were analyzed for emergent themes using thematic analysis, maintaining reflexivity. DISCUSSION: Four themes were identified: Intentionality to diversity faculty, Plan for professional development, Clear antiracism diversity equity and inclusion standards, and Retention enablers and barriers. CONCLUSION: We provide strategies (e.g., targeted resources, diverse cluster hires, building community) to inform recruitment and retention of early-career faculty of color.

RESUMEN

THEORETICAL PRINCIPLES: Social Cognitive Theory (SCT) is a middle-range theory with triadic determinism between behavioral, environmental, and personal. SCT has been a guiding framework in health promotion research as it helps understand people's behaviors. PHENOMENA ADDRESSED: Behavioral Insomnia of Childhood (BIC) is highly prevalent, affecting up to 45% of typically developing children and 80% of children with special healthcare needs. BIC leads to sleep deficiency, disrupted physical and psychological health, poor school performance, behavioral dysfunction, and negatively affects parental and family functioning. Using Fawcett's framework, we analyzed and evaluated SCT in a pediatric sleep context and propose a reformulation of SCT to better inform sleep research. RESEARCH LINKAGES: SCT is individually focused and does not account for interdependence within relationships. Pediatric sleep interventions have limited long-term effects and sustainability without considering the parent-child dyadic interdependency. We advance the argument that the parent-child shared management (PCSM) perspective is beneficial for understanding pediatric sleep health. PCSM is a concept that reflects the shared responsibility and interdependence that parent and child have for managing child health. It assumes that with parents' ongoing support, children's responsibility for their health management increases over time, along with developmental progression and health-related experiences. We propose reformulating SCT by integrating PCSM in the pediatric sleep context: SCT with Shared Management (SCT-SM). The proposed SCT-SM accounts for parent-child interdependence and role transition. Shared management interventions that engage parents and children in active roles in managing sleep have potential sustainable effects in improving sleep and quality of life. (250).

RESUMEN

Cyclin-dependent kinase 4/6 (CDK4/6) inhibitors are an established treatment in estrogen receptor-positive breast cancer and are currently in clinical development in melanoma, a tumor that exhibits high rates of CDK4 activation. We analyzed melanoma cells with acquired resistance to the CDK4/6 inhibitor palbociclib and demonstrate that the activity of PRMT5, a protein arginine methyltransferase and indirect target of CDK4, is essential for CDK4/6 inhibitor sensitivity. By indirectly suppressing PRMT5 activity, palbociclib alters the pre-mRNA splicing of MDM4, a negative regulator of p53, leading to decreased MDM4 protein expression and subsequent p53 activation. In turn, p53 induces p21, leading to inhibition of CDK2, the main kinase substituting for CDK4/6 and a key driver of resistance to palbociclib. Loss of the ability of palbociclib to regulate the PRMT5-MDM4 axis leads to resistance. Importantly, combining palbociclib with the PRMT5 inhibitor GSK3326595 enhances the efficacy of palbociclib in treating naive and resistant models and also delays the emergence of resistance. Our studies have uncovered a mechanism of action of CDK4/6 inhibitors in regulating the MDM4 oncogene and the tumor suppressor, p53. Furthermore, we have established that palbociclib inhibition of the PRMT5-MDM4 axis is essential for robust melanoma cell sensitivity and provide preclinical evidence that coinhibition of CDK4/6 and PRMT5 is an effective and well-tolerated therapeutic strategy. Overall, our data provide a strong rationale for further investigation of novel combinations of CDK4/6 and PRMT5 inhibitors, not only in melanoma but other tumor types, including breast, pancreatic, and esophageal carcinoma.

RESUMEN

OBJECTIVE/BACKGROUND: Insufficient and/or poor-quality sleep may contribute to poor social-emotional well-being, and vice versa, among young children who have experienced maltreatment. This study examined longitudinal associations between sleep and social-emotional functioning among a sample of infants and toddlers from families involved with Child Protective Services (CPS) for maltreatment. PARTICIPANTS: Participants were 123 parents and their infant or toddler (baseline age 10 to 24 months) from families referred to CPS for maltreatment. METHODS: Data were collected at baseline and at 3, 6 and 9 months post-baseline. At all time points, parents completed a questionnaire about their child's social-emotional functioning including internalizing behavior, externalizing behavior, and competence in social-emotional skills and social relatedness. At 3 months post-baseline, parents reported about their child's sleep problems and daily napping behavior. RESULTS: Higher baseline externalizing behavior was associated with a greater propensity for sleep problems at 3 months post-baseline. Sleep problems at 3 months post-baseline were associated with higher internalizing and higher externalizing behavior at 9 months post-baseline. Daily napping at 3 months post-baseline was associated with lower internalizing behavior, lower externalizing behavior, and higher competence at 9 months post-baseline. CONCLUSIONS: Among this sample of young children from families involved with CPS for maltreatment, parents' concerns about their child having a sleep problem longitudinally associated with children's internalizing and externalizing behavior. Children's daily napping behavior longitudinally associated with later internalizing behavior, externalizing behavior, and competence.

RESUMEN

PURPOSE: To describe sleep patterns, problems, and ecology among toddlers (13 to 36 months) from families referred to Child Protective Services (CPS) for maltreatment and to compare sleep duration among a subgroup (24- to 36-month-olds) to previously published population-based data. DESIGN AND METHODS: A secondary analysis of a larger longitudinal study was conducted. Participants included 113 parent-toddler dyads recruited out of CPS offices based on having a recent maltreatment referral. Parents reported about their toddler's sleep at two time points (approximately six months apart). RESULTS: At the earlier and later time points, respectively, mean sleep duration was 11.03 and 10.90 h (nighttime), 1.36 and 1.36 h (daytime), and 12.47 and 12.28 h (total 24-h). Of the toddlers, 24% and 17% had two or more nighttime awakenings, 34% and 33% had at least a somewhat hard time falling asleep, and 25% and 26% had difficulty sleeping alone. Mean bedtimes were 8:50 pm and 8:58 pm. Nighttime sleeping arrangement/location, nap arrangement/location, and method of falling asleep at night varied. Compared to the population-based data, nighttime sleep duration was 43 min longer and nap duration was 46 min shorter in the CPS sample. CONCLUSIONS: Symptoms of behavioral sleep problems were common in this sample of toddlers from families referred to CPS for maltreatment. Distribution of sleep, but not total 24-hour sleep, differed significantly between the CPS sample and the population-based data. PRACTICE IMPLICATIONS: Nurses caring for toddlers from families involved with CPS can play an integral role promoting sleep health and addressing behavioral sleep problems.

RESUMEN

Children, parents, older adults, and caregivers routinely use sensor technology as a source of health information and health monitoring. The purpose of this paper is to describe three exemplars of research that used a human-centered approach to engage participants in the development, design, and usability of interventions that integrate technology to promote health. The exemplars are based on current research studies that integrate sensor technology into pediatric, adult, and older adult populations living with a chronic health condition. Lessons learned and considerations for future studies are discussed. Nurses have successfully implemented interventions that use technology to improve health and detect, prevent, and manage diseases in children, families, individuals and communities. Nurses are key stakeholders to inform clinically relevant health monitoring that can support timely and personalized intervention and recommendations.

RESUMEN

The aim of this study was to investigate the association between sleep duration, overweight/obesity, and school failure using data obtained from self-reported questionnaires completed by 13- to 15-year-olds in Sweden (n = 1,363; 50.7% female). The height and weight of the participants were measured by school nurses. A multiple logistic regression analysis was used to analyze the association between sleep duration and overweight/obesity, school failure, and perceived economic situation. A short sleep duration (<7 hr) was associated with overweight/obesity (p = .001), school failure (p = .007), and poorer perceived economic situation (p = .004). Modifying the sleep habits of adolescents is a potential target for obesity intervention as well as for improving school success. This information is particularly well suited for school nurses to disseminate to students and their parents.

RESUMEN

PURPOSE: This article outlines how current nursing research can utilize technology to advance symptom and self-management science for precision health and provides a roadmap for the development and use of technologies designed for this purpose. APPROACH: At the 2018 annual conference of the National Institute of Nursing Research (NINR) Research Centers, nursing and interdisciplinary scientists discussed the use of technology to support precision health in nursing research projects and programs of study. Key themes derived from the presentations and discussion were summarized to create a proposed roadmap for advancement of technologies to support health and well-being. CONCLUSIONS: Technology to support precision health must be centered on the user and designed to be desirable, feasible, and viable. The proposed roadmap is composed of five iterative steps for the development, testing, and implementation of technology-based/enhanced self-management interventions. These steps are (a) contextual inquiry, focused on the relationships among humans, and the tools and equipment used in day-to-day life; (b) value specification, translating end-user values into end-user requirements; (c) design, verifying that the technology/device can be created and developing the prototype(s); (d) operationalization, testing the intervention in a real-world setting; and (e) summative evaluation, collecting and analyzing viability metrics, including process data, to evaluate whether the technology and the intervention have the desired effect. CLINICAL RELEVANCE: Interventions using technology are increasingly popular in precision health. Use of a standard multistep process for the development and testing of technology is essential.

RESUMEN

BACKGROUND: Precision health considers individual lifestyle, genetics, behaviors, and environment context and facilitates interventions aimed at helping individuals achieve well-being and optimal health. PURPOSE: To present the Nursing Science Precision Health (NSPH) Model and describe the integration of precision health concepts within the domains of symptom and self-management science as reflected in the National Institute of Nursing Research P30 Centers of Excellence and P20 Exploratory Centers. METHODS: Center members developed the NSPH Model and the manuscript based on presentations and discussions at the annual NINR Center Directors Meeting and in follow-up telephone meetings. DISCUSSION: The NSPH Model comprises four precision components (measurement; characterization of phenotype including lifestyle and environment; characterization of genotype and other biomarkers; and intervention target discovery, design, and delivery) that are underpinned by an information and data science infrastructure. CONCLUSION: Nurse scientist leadership is necessary to realize the vision of precision health as reflected in the NSPH Model.

RESUMEN

PURPOSE: Biomarkers as common data elements (CDEs) are important for the characterization of biobehavioral symptoms given that once a biologic moderator or mediator is identified, biologically based strategies can be investigated for treatment efforts. Just as a symptom inventory reflects a symptom experience, a biomarker is an indicator of the symptom, though not the symptom per se. The purposes of this position paper are to (a) identify a "minimum set" of biomarkers for consideration as CDEs in symptom and self-management science, specifically biochemical biomarkers; (b) evaluate the benefits and limitations of such a limited array of biomarkers with implications for symptom science; (c) propose a strategy for the collection of the endorsed minimum set of biologic samples to be employed as CDEs for symptom science; and (d) conceptualize this minimum set of biomarkers consistent with National Institute of Nursing Research (NINR) symptoms of fatigue, depression, cognition, pain, and sleep disturbance. DESIGN AND METHODS: From May 2016 through January 2017, a working group consisting of a subset of the Directors of the NINR Centers of Excellence funded by P20 or P30 mechanisms and NINR staff met bimonthly via telephone to develop this position paper suggesting the addition of biomarkers as CDEs. The full group of Directors reviewed drafts, provided critiques and suggestions, recommended the minimum set of biomarkers, and approved the completed document. Best practices for selecting, identifying, and using biological CDEs as well as challenges to the use of biological CDEs for symptom and self-management science are described. Current platforms for sample outcome sharing are presented. Finally, biological CDEs for symptom and self-management science are proposed along with implications for future research and use of CDEs in these areas. FINDINGS: The recommended minimum set of biomarker CDEs include pro- and anti-inflammatory cytokines, a hypothalamic-pituitary-adrenal axis marker, cortisol, the neuropeptide brain-derived neurotrophic factor, and DNA polymorphisms. CONCLUSIONS: It is anticipated that this minimum set of biomarker CDEs will be refined as knowledge regarding biologic mechanisms underlying symptom and self-management science further develop. The incorporation of biological CDEs may provide insights into mechanisms of symptoms, effectiveness of proposed interventions, and applicability of chosen theoretical frameworks. Similarly, as for the previously suggested NINR CDEs for behavioral symptoms and self-management of chronic conditions, biological CDEs offer the potential for collaborative efforts that will strengthen symptom and self-management science. CLINICAL RELEVANCE: The use of biomarker CDEs in biobehavioral symptoms research will facilitate the reproducibility and generalizability of research findings and benefit symptom and self-management science.

RESUMEN

The aim of this study was to examine sleep habits (i.e., bedtimes and rising times) and their association with nighttime text messaging in 15- to 17-year-old adolescents. This cross-sectional study analyzed data from a web-based survey of adolescent students attending secondary schools in southern Sweden ( N = 278, 50% female). Less than 8 hr of time in bed during school nights was significantly associated with more sleep difficulties, wake time variability on school days and weekends, daytime tiredness, and less enjoyment at school (all ps < .05). Sending and/or receiving text messages (Short Message Service [SMS]) at night was significantly associated with later bedtimes, shorter time in bed, daytime tiredness during school, and irregular sleep habits ( p < .05). These findings highlight the importance of regular, consistent sleep habits and the problems associated with sleeping with a cell phone in the bedroom.

RESUMEN

PURPOSE: To examine the congruence between polysomnography obstructive apnea hypopnea index (OAHI) and parent-reported obstructive sleep apnea (OSA) symptoms in 6- to 11-year-old children with juvenile idiopathic arthritis (JIA) and controls; and to compare fatigue and quality of life in JIA and control children based on OAHI and OSA symptoms. METHODS: Sixty-eight children with JIA and 75 controls and a parent participated. Children underwent one night of polysomnography in a sleep laboratory. Parents completed the sleep-related breathing disorders scale-pediatric sleep questionnaire (PSQ), and both children and parents completed the Pediatric Quality of Life Generic Core Scale and the Multidimensional Fatigue Scale. RESULTS: In JIA, 86% who met the OAHI clinical criteria for OSA (≥1.5) were above the PSQ OSA symptom cut-off score with a sensitivity of 0.86 and a specificity of 0.28. In the control group, 63% who met the OAHI clinical criteria for OSA were above the PSQ OSA symptom cut-off score, with a sensitivity of 0.63 and a specificity of 0.42. All children above both the clinical criteria for OAHI and OSA symptom cut-off score had the most impaired quality of life and greater fatigue compared to those below both the clinical criteria for OAHI and the OSA symptom cut-off score. CONCLUSION: Children who meet clinical criteria for OSA and also scored high on a parent-reported screening tool for OSA symptoms had the most impaired quality of life and more fatigue. The PSQ has potential to identify children at risk for OSA.

RESUMEN

PURPOSE: The purpose of this study is to describe parents' experiences in caring for 2-5-year-old children with juvenile idiopathic arthritis (JIA). DESIGN AND METHODS: A qualitative study using single-occasion in-depth interviews was conducted. Nine parents (eight mothers and one father) were interviewed in-person or via telephone. Data were analyzed using inductive content analysis. Methods used to protect the trustworthiness of study results included maintenance of an audit trail, peer debriefing, and member checks. RESULTS: The core construct Struggling in the Dark to Help My Child explained parents' experience in six domains: not knowing, trying to reach out in the dark, feeling my child's pain, working out the kinks to stay on top to manage, feeling drained by the whole process, and being hard on the entire household. Parents struggled with the unknown, searched for resources, witnessed their child's suffering without knowing how to help, and tried every possible way to stay on top of the child's illness and treatment, even when they felt drained physically and emotionally. JIA not only consumed their lives, but also affected the entire family, including the siblings and spouse, and the relationships among family members. CONCLUSION AND IMPLICATIONS: Findings highlight the day-to-day lived challenges parents face when caring for a young child with JIA. Healthcare providers including nurses need to assess the particular needs of an ill child and parents as well as the impact of the illness on the physical and psychosocial health of the entire family so that proper resources can be provided.

RESUMEN

OBJECTIVES: Describe daily sleep patterns, sleep quality, and sleep hygiene in 2-5-year-old children newly diagnosed with juvenile idiopathic arthritis (JIA) and their parents in comparison with typically developing (TD) children and parents. METHODS: Participants (13 JIA, 16 TD parent-child dyads) wore actigraphs for 10 days. Parents completed sleep diaries and sleep hygiene survey. RESULTS: Children with JIA had significantly less total sleep time, lower sleep efficiency (SE), and longer naps than TD children. Parents of children with JIA had significantly earlier bedtimes, more wake after sleep onset (WASO) and lower SE than TD parents. Parent-child SE and WASO were interrelated in JIA dyads. Sleep hygiene practices were inconsistent in both groups of children. CONCLUSIONS: Inadequate amounts of sleep and poor sleep quality were common in parent-child dyads. Early interventions to improve sleep duration and promote sleep hygiene practices may alleviate future sleep problems and improve parent and child well-being.

RESUMEN

Overexpression of the prosurvival protein BCL-2 is common in breast cancer. Here we have explored its role as a potential therapeutic target in this disease. BCL-2, its anti-apoptotic relatives MCL-1 and BCL-XL, and the proapoptotic BH3-only ligand BIM were found to be coexpressed at relatively high levels in a substantial proportion of heterogeneous breast tumors, including clinically aggressive basal-like cancers. To determine whether the BH3 mimetic ABT-737 that neutralizes BCL-2, BCL-XL, and BCL-W had potential efficacy in targeting BCL-2-expressing basal-like triple-negative tumors, we generated a panel of primary breast tumor xenografts in immunocompromised mice and treated recipients with either ABT-737, docetaxel, or a combination. Tumor response and overall survival were significantly improved by combination therapy, but only for tumor xenografts that expressed elevated levels of BCL-2. Treatment with ABT-737 alone was ineffective, suggesting that ABT-737 sensitizes the tumor cells to docetaxel. Combination therapy was accompanied by a marked increase in apoptosis and dissociation of BIM from BCL-2. Notably, BH3 mimetics also appeared effective in BCL-2-expressing xenograft lines that harbored p53 mutations. Our findings provide in vivo evidence that BH3 mimetics can be used to sensitize primary breast tumors to chemotherapy and further suggest that elevated BCL-2 expression constitutes a predictive response marker in breast cancer.

RESUMEN

The study compared sleep disturbances and behavior problems in school-age children with and without juvenile idiopathic arthritis (JIA). Children 6-to-11 years of age, with (n=70) and without (n=46) JIA, and their parent participated. Parents completed questionnaires on sleep habits and behavior problems. Compared to control children, JIA children had significantly higher total sleep disturbances and higher scores on six of eight subscales. Sleep disturbances predicted externalizing behavior problems, controlling for age, medications, study group, and pain. Sleep disturbances such as, sleep disordered breathing are often overlooked or unrecognized in JIA and may contribute to behavioral problems.

RESUMEN

Inadequate sleep occurs in 25% of our nation's children; poor sleep is associated with physical, cognitive, and social consequences. Developing good sleep hygiene in middle childhood is important, because habits typically extend to adolescence and adulthood; yet, there has been little research on sleep interventions for school-age children. The purpose of this study was to determine the feasibility of a developmentally tailored, motivation-based intervention (MBI) focused on improving sleep behaviors in school-age children aged 8-11. Nine parent-child dyads participated in an 8-week protocol utilizing MBI and comparisons of objective (actigraphy) and subjective (sleep diaries) data. Results suggest that parent and children are able to identify a target behavior to change and complete the protocol. Further, preliminary evidence indicates that sleep patterns change using MBI. Future research will be directed toward comparative effectiveness testing and exploring ways in which it can be adapted and incorporated into school nursing practice.

RESUMEN

INTRODUCTION: Systemic lupus erythematosus (SLE) is a chronic autoimmune disorder characterized by recurrent episodes of pain. This study aimed to describe the temporal daily relationships between sleep and pain in adolescents with SLE. METHOD: Twenty-three adolescents with SLE recruited from a pediatric hospital wore actigraphy and completed diaries. Generalized estimating equation models were used. RESULTS: On average, evening pain negatively predicted subsequent sleep quality that night, and, on average, sleep quality negatively predicted morning pain. Shorter total sleep time significantly predicted higher morning pain (95% confidence intervals [CI], -0.38 to -0.03, p = .02), whereas sleep efficiency and sleep quality were not significantly associated with morning pain (95% CI, -0.03 to 0.03; 95% CI, -0.08 to 0.06, respectively). Subsequent evening pain did not predict daily nighttime sleep DISCUSSION: Our findings suggest that sleep is a target for pain interventions to include among adolescents with SLE.

RESUMEN

STUDY OBJECTIVES: To describe and compare sleep deficiency and symptoms of pain, fatigue, and depressed mood in youth with childhood Systemic lupus erythematosus (cSLE) to a healthy comparison group of youth; and to test the associations between sleep and symptoms of pain, fatigue, and depressed mood in youth with cSLE. METHODS: Forty-three youth (23 youth with cSLE; 20 age, sex-matched healthy youth) wore actigraphs and completed sleep diaries for 10 days, and completed self-report questionnaires on sleep quality, pain, fatigue, and depressed mood. RESULTS: On average, both groups had a total sleep time of less than 7 hours. Youth with cSLE had worse sleep efficiency (73.3%) and sleep regularity index scores (55.4) compared to the healthy comparison group of youth (79.2%, 60.1, respectively). Youth with cSLE had worse pain (p = .03) and fatigue (p = .004) compared to the healthy comparison group. Negative associations were found among self-reported sleep quality, sleep satisfaction, and symptoms of pain, fatigue, and depressed mood in youth with cSLE and wake after sleep onset was positively associated with fatigue. CONCLUSIONS: Poor sleep efficiency and sleep irregularity accompanied by symptoms of pain, fatigue, and depressed mood was prevalent in youth with cSLE. Youth with lupus should be encouraged to maintain a regular sleep schedule. Since, this is the first study to incorporate objective sleep and sleep regularity measures in youth with cSLE, additional studies with objective and self-report sleep measures are needed to replicate our findings.
