Emergency Department Patients' COVID-19 Vaccination Status and Self-Reported Barriers.

INTRODUCTION: This study surveyed adult emergency department (ED) patients and the adult companions of pediatric patients to determine whether rates of coronavirus disease 2019 (COVID-19) vaccination were comparable to that of the general population in the region. This study also sought to identify self-reported barriers to vaccination and possible areas for intervention. METHODS: A survey was administered to 607 adult ED patients or the adult companions of pediatric patients from three different regional hospitals to assess their COVID-19 vaccination status, COVID-19 vaccine barriers, and demographic information. RESULTS: Of the 2,267 adult patients/companions considered for enrollment, we approached 730 individuals about participating in the study. Of the individuals approached, 607 (41% male; mean age 47.0+17.4 years) consented to participate. A total of 403 (66.4%) participants had received at least one vaccine dose as compared to 70% of the adult population in the county where the three hospitals were located. Of those, 382 (94.8%) were fully vaccinated and among the individuals who were partially vaccinated the majority (17 of 21) had an appointment for their second dose. Of those approached, 204 (33.6%) were not vaccinated, with 66 (10.9% of the total population) expressing an interest in becoming vaccinated while the remaining 138 did not want to be vaccinated. Of those who wanted to be vaccinated 32% were waiting for more safety data, and of those who did not want to be vaccinated 26% were concerned about side effects and risks and 28% were waiting for more safety data. CONCLUSION: Adult ED patients and adult companions of pediatric ED patients were vaccinated at a slightly lower rate than the general population in our county. A small but significant proportion of those who were unvaccinated expressed the desire to be vaccinated, indicating that the ED may be a suitable location to introduce a COVID-19 vaccination program.

Sleep Well! An adapted behavioral sleep intervention implemented in urban primary care.

STUDY OBJECTIVES: To describe the adaptation, feasibility, and initial outcomes of Sleep Well!, an intervention for early childhood insomnia and insufficient sleep, designed for families from lower-socioeconomic status backgrounds presenting to large metropolitan primary care sites. METHODS: Fifteen caregiver-child dyads (caregivers: 92.3% mothers, 80.0% Black, 53.3% ≤ 125% US poverty level; children: 73.3% female, 86.7% Black, mean age = 3.0 years) participated in this multimethod, single-arm trial. A family advisory board of caregivers (n = 4) and a clinician advisory board of sleep experts, primary care clinicians, and psychologists (n = 13) provided intervention feedback throughout the pilot. Most adaptations were related to intervention delivery methods, with some related to sleep strategies. At postintervention, caregivers completed surveys on intervention acceptability and cultural humility (primary outcomes) and completed semistructured interviews. Caregivers also reported on child sleep pre- and postintervention. RESULTS: Thirteen (86.6%) families completed Sleep Well! and 12 (80.0%) completed pre- and postintervention measures. Caregivers reported strong intervention acceptability and cultural humility. There were preintervention to postintervention reductions in child sleep problems, bedroom electronics, sleep onset latency, and night awakening frequency and duration. Nighttime sleep duration and overall insufficient sleep also improved. Qualitative data also showed strong intervention acceptability and perceived flexibility, with few participation barriers. CONCLUSIONS: A brief, early childhood behavioral sleep intervention delivered in primary care with families from primarily lower-socioeconomic status backgrounds and/or racially minoritized backgrounds is feasible to implement, with strong retention rates, acceptability, and perceptions of cultural humility. Child sleep improvements are positive and warrant replication in a randomized controlled trial.

Ecosystem-based management of coral reefs under climate change.

Coral reefs provide food and livelihoods for hundreds of millions of people as well as harbour some of the highest regions of biodiversity in the ocean. However, overexploitation, land-use change and other local anthropogenic threats to coral reefs have left many degraded. Additionally, coral reefs are faced with the dual emerging threats of ocean warming and acidification due to rising CO 2 emissions, with dire predictions that they will not survive the century. This review evaluates the impacts of climate change on coral reef organisms, communities and ecosystems, focusing on the interactions between climate change factors and local anthropogenic stressors. It then explores the shortcomings of existing management and the move towards ecosystem-based management and resilience thinking, before highlighting the need for climate change-ready marine protected areas (MPAs), reduction in local anthropogenic stressors, novel approaches such as human-assisted evolution and the importance of sustainable socialecological systems. It concludes that designation of climate change-ready MPAs, integrated with other management strategies involving stakeholders and participation at multiple scales such as marine spatial planning, will be required to maximise coral reef resilience under climate change. However, efforts to reduce carbon emissions are critical if the long-term efficacy of local management actions is to be maintained and coral reefs are to survive.

Identifying early changes in myocardial microstructure in hypertensive heart disease.

The transition from healthy myocardium to hypertensive heart disease is characterized by a series of poorly understood changes in myocardial tissue microstructure. Incremental alterations in the orientation and integrity of myocardial fibers can be assessed using advanced ultrasonic image analysis. We used a modified algorithm to investigate left ventricular myocardial microstructure based on analysis of the reflection intensity at the myocardial-pericardial interface on B-mode echocardiographic images. We evaluated the extent to which the novel algorithm can differentiate between normal myocardium and hypertensive heart disease in humans as well as in a mouse model of afterload resistance. The algorithm significantly differentiated between individuals with uncomplicated essential hypertension (N = 30) and healthy controls (N = 28), even after adjusting for age and sex (P = 0.025). There was a trend in higher relative wall thickness in hypertensive individuals compared to controls (P = 0.08), but no difference between groups in left ventricular mass (P = 0.98) or total wall thickness (P = 0.37). In mice, algorithm measurements (P = 0.026) compared with left ventricular mass (P = 0.053) more clearly differentiated between animal groups that underwent fixed aortic banding, temporary aortic banding, or sham procedure, on echocardiography at 7 weeks after surgery. Based on sonographic signal intensity analysis, a novel imaging algorithm provides an accessible, non-invasive measure that appears to differentiate normal left ventricular microstructure from myocardium exposed to chronic afterload stress. The algorithm may represent a particularly sensitive measure of the myocardial changes that occur early in the course of disease progression.
