Effect of Play2Sleep on mother-reported and father-reported infant sleep: a sequential explanatory mixed-methods study of a randomized controlled trial.

STUDY OBJECTIVES: This study evaluated the effect on infant sleep of a novel intervention (Play2Sleep) that combined infant sleep information with self-modeled video feedback on parent-infant interactions. METHODS: An explanatory sequential mixed-methods design consisting of a randomized controlled trial with 63 mother-father-infant triads randomized to Play2Sleep or comparison home visit interventions was used. We used repeated measures analysis of covariance to detect changes in infant night wakings, nocturnal wakefulness, and sleep durations and Wilcoxon signed rank test to evaluate changes in perception of infant sleep problems. Family interviews (n = 20) were used to explain the quantitative findings and analyzed qualitatively using thematic analysis. RESULTS: Play2Sleep was effective in reducing maternal-reported infant wakefulness, F(1,55) = 5.33, P = .03, partial η2 = .09, and the number of paternal-reported naps, F(1,58) = 4.90, P = .03, partial η2 = .08. Parents in the Play2Sleep group reported significant improvements in problematic infant sleep that were not observed in the comparison group; however, Play2Sleep was not effective in reducing the number of parent-reported night wakings. Information overwhelm, learning infant cues, and working together with a subtheme of father involvement were key qualitative themes developed to explain the quantitative results. Unplanned exploratory analyses revealed a significant improvement in maternal depression symptoms in the Play2Sleep group. CONCLUSIONS: This study suggests Play2Sleep could improve infant sleep by promoting parental awareness of infant cues and father involvement and improving maternal depression. Additional research is needed to determine the optimal number and timing of sessions.

Using wearable and mobile technology to measure and promote healthy sleep behaviors in adolescents: a scoping review protocol.

OBJECTIVE: The objective of this scoping review is to map the evidence related to how consumer-targeted wearable and mobile technology is being used to measure and/or promote sleep among adolescents. INTRODUCTION: Sleep is a key component of physical and mental health and is required for healthy development in adolescence. Efforts to improve insufficient and poor-quality sleep among adolescents have resulted in limited and temporary enhancements in sleep habits. Since good sleep hygiene is established through the development of daily routines, wearable technology offers a potential solution by providing real-time feedback, allowing adolescents to monitor and manage their sleep habits. INCLUSION CRITERIA: Studies that focus on adolescents between 13 and 24 years who use mobile or wearable technology to measure and/or promote sleep health will be considered for inclusion. METHODS: Using a scoping methodology, the authors will conduct a review of studies on the use of commercially available, wearable technology or mobile devices designed to measure and/or improve sleep among adolescents. Literature searched will include published primary studies, reviews, and dissertations from database inception to present. Databases searched will include MEDLINE, Embase, PsycINFO, CINAHL, CENTRAL, SPORTDiscus, JBI Evidence Synthesis, Cochrane Database of Systematic Reviews, Scopus, and ProQuest Dissertations and Theses. The search will be conducted using identified keywords and indexed terms, and studies will be limited to the English language. Data extracted will include study population, methods, description of sleep technology reported, sleep outcomes, and strategies used to promote healthy sleep behaviors. Quality assessment of included studies will be conducted to facilitate data mapping and synthesis.

Recruitment and retention of fathers with young children in early childhood health intervention research: a systematic review and meta-analysis protocol.

BACKGROUND: Fathers are under-represented in research and programs addressing early childhood health and development. Recruiting fathers into these interventions can be hampered for multiple reasons, including recruitment and retention strategies that are not tailored for fathers. The primary aim of this systematic review and meta-analysis is to determine the effectiveness of recruitment and retention strategies used to include fathers of children (from conception to age 36 months) in intervention studies. The secondary aim is to investigate study-level factors that may influence recruitment and retention. METHODS: We will conduct searches for scholarly peer-reviewed randomized controlled trials, quasi-experimental studies, and pre-post studies that recruited fathers using the following databases: MEDLINE (Ovid), EMBASE (Ovid), PsycINFO (Ovid), and CINAHL. English-language articles will be eligible if they recruited self-identified fathers of children from conception to age 36 months for health-promoting interventions that target healthy parents and children. Two reviewers will independently screen titles/abstracts and full texts for inclusion, as well as grading methodological quality. Recruitment and retention proportions will be calculated for each study. Where possible, we will calculate pooled proportional effects with 95% confidence intervals using random-effects models and conduct a meta-regression to examine the impact of potential modifiers of recruitment and retention. DISCUSSION: Findings from this review will help inform future intervention research with fathers to optimally recruit and retain participants. Identifying key factors should enable health researchers and program managers design and adapt interventions to increase the likelihood of increasing father engagement in early childhood health interventions. Researchers will be able to use this review to inform future research that addresses current evidence gaps for the recruitment and retention of fathers. This review will make recommendations for addressing key target areas to improve recruitment and retention of fathers in early childhood health research, ultimately leading to a body of evidence that captures the full potential of fathers for maximizing the health and wellbeing of their children.

Study Protocol: Determining Research Priorities of Young Albertan Families (The Family Research Agenda Initiative Setting Project-FRAISE)-Participatory Action Research.

Introduction: Pregnancy and childrearing can be an exciting and stressful time for new parents. The maternal-child health landscape has changed dramatically over the last few decades and research priorities need to address these rapid changes. There have been limited attempts to engage and collaborate with members of the public to develop research priorities for families who are expecting or parenting an infant to age 24 months. The work that has been completed has attempted to identify parental preference for information delivery and barriers to uptake of parenting programs but has not investigated parental research priorities. Methods: In collaboration with provincial research units and strategic clinical networks (SCN), we will use principles of participatory action research (PAR) as our theoretical framework/method, and a modified James Lind Alliance priority setting approach to prioritize a list of research questions that parents/knowledge users believe will support the health of their families. This will result in a top 10 list of parent/knowledge user-identified research priorities. This project will consist of three phases. In the first phase, we developed a steering committee of parents/knowledge users, healthcare providers, community agencies, and researchers to design a survey about health priorities for families. In the second phase, we will distribute the survey to diverse groups of parents/knowledge users/providers and hold a series of meetings to identify and prioritize potential questions from new parents about health issues from conception to age 24 months. In the third phase, we will collaboratively disseminate and translate findings. Discussion: This study will highlight parental health concerns and recommend parent-identified research priorities to inform future research projects needed to support the health of families between conception to age 24 months. Understanding the health research priorities of families in the community will help ensure future research contributes to meaningful changes in the health of young children, parents/knowledge users, and families. Ethics: This study and protocol have received ethical approved from the Conjoint Health Research Ethics Board at the University of Calgary (REB17-0014). Dissemination: The top 10 research priorities will be published and additional findings from the study will be distributed through pamphlets and newsletters.

A Proposed Nursing Theory: Infant Sleep and Development.

Although well positioned to work with families of young children, nurses do not yet have a theory that guides practice and research by relating infant sleep to child and family development. The authors of this paper describe a proposed theory that combines Bronfenbrenner's bioecological theory of human development with the Barnard model of parent-child interaction to inform nursing practice and research related to infant sleep and optimizing child and family development. The theory focuses on sustainability of change in family processes and infant sleep, with a goal of optimizing family wellness as the proximal environment for child development.

The New Parent Checklist: A Tool to Promote Parental Reflection.

PURPOSE: To design and establish content and face validity of an evidence-informed tool that promotes parental self-reflection during the transition to parenthood. STUDY DESIGN AND METHODS: The New Parent Checklist was developed using a three-phase sequential approach: Phase 1 a scoping review and expert consultation to develop and refine a prototype tool; Phase 2 content analysis of parent focus groups; and Phase 3 assessment of utility in a cross-sectional sample of parents completing the New Parent Checklist and a questionnaire. RESULTS: The initial version of the checklist was considered by experts to contain key information. Focus group participants found it useful, appropriate, and nonjudgmental, and offered suggestions to enhance readability, utility, as well as face and content validity. In the cross-sectional survey, 83% of the participants rated the New Parent Checklist as "helpful" or "very helpful" and 90% found the New Parent Checklist "very easy" to use. Open-ended survey responses included predominantly positive feedback. Notable differences existed for some items based on respondents' first language, age, and sex. Results and feedback from all three phases informed the current version, available for download online. CLINICAL IMPLICATIONS: The New Parent Checklist is a comprehensive evidence-informed self-reflective tool with promising content and face validity. Depending on parental characteristics and infant age, certain items of the New Parent Checklist have particular utility but may also require further adaptation and testing. Local resources for information and/or support are included in the tool and could be easily adapted by other regions to incorporate their own local resources.

Bed Sharing, SIDS Research, and the Concept of Confounding: A Review for Public Health Nurses.

Confounding is an important concept for public health nurses (PHNs) to understand when considering the results of epidemiological research. The term confounding is derived from Latin, confundere, which means to "mix-up" or "mix together". Epidemiologists attempt to derive a cause and effect relationship between two variables traditionally known as the exposure and disease (e.g., smoking and lung cancer). Confounding occurs when a third factor, known as a confounder, leads to an over- or underestimate of the magnitude of the association between the exposure and disease. An understanding of confounding will facilitate critical appraisal of epidemiological research findings. This knowledge will enable PHNs to strengthen their evidence-based practice and better prepare them for policy development and implementation. In recent years, researchers and clinicians have examined the relationship between bed sharing and sudden infant death syndrome (SIDS). The discussion regarding the risk of bed sharing and SIDS provides ample opportunity to discuss the various aspects of confounding. The purpose of this article is to use the bed sharing and SIDS literature to assist PHNs to understand confounding and to apply this knowledge when appraising epidemiological research. In addition, strategies that are used to control confounding are discussed.

Platelet TLR4 activates neutrophil extracellular traps to ensnare bacteria in septic blood.

It has been known for many years that neutrophils and platelets participate in the pathogenesis of severe sepsis, but the inter-relationship between these players is completely unknown. We report several cellular events that led to enhanced trapping of bacteria in blood vessels: platelet TLR4 detected TLR4 ligands in blood and induced platelet binding to adherent neutrophils. This led to robust neutrophil activation and formation of neutrophil extracellular traps (NETs). Plasma from severely septic humans also induced TLR4-dependent platelet-neutrophil interactions, leading to the production of NETs. The NETs retained their integrity under flow conditions and ensnared bacteria within the vasculature. The entire event occurred primarily in the liver sinusoids and pulmonary capillaries, where NETs have the greatest capacity for bacterial trapping. We propose that platelet TLR4 is a threshold switch for this new bacterial trapping mechanism in severe sepsis.
