    Abstract Pain is the leading cause of emergency department (ED) visits for individuals living with sickle cell disease (SCD). The care that is delivered in the ED is often cited by patients with SCD as the area of health care in greatest need of improvement. In 2014, the National Heart, Lung, and Blood Institute released guidelines for the care of SCD, including recommendations for the management of acute sickle cell pain in the ED. These guidelines provide a framework to understand the elements of ideal emergency sickle cell pain care; however, they do not provide guidance on barriers and facilitators to achieving these ideals in the complex system of the ED. Presented in this article are 4 tenets of implementing guideline-adherent emergency sickle cell care gleaned from the available literature and continuous quality improvement efforts at our institution. These include: (1) strategies to reduce negative provider attitudes toward patients with SCD; (2) strategies to reduce time-to-first-dose of analgesic medication; (3) strategies to improve ED pain care beyond the first dose of medication; and (4) strategies to improve ED patient safety. Application of the principles discussed within can improve patient and provider satisfaction, quality, and safety.

    Abstract This is a revised second edition of the most detailed, comprehensive, and user-friendly photographic field guide to the butterflies of North America. Written by Jeffrey Glassberg, the pioneering authority on the field identification of butterflies, the guide covers all known species, beautifully illustrating them with 3,500 large, gorgeous color photographs-the very best images available. This second edition includes more than 500 new photos and updated text, maps, and species names. For most species, there are photographs of topsides and undersides, males and females, and variants. All text is embedded in the photographs, allowing swift access in the field, and arrows point to field marks, showing you exactly what to look for. Detailed, same-page range maps include information about the number of broods in each area and where strays have been recorded. Color text boxes highlight information about habitat, caterpillar food plants, abundance and flight period, and other interesting facts. Also included are a quick visual index and a caterpillar food plant index. The result is an ideal field guide that will enable you to identify almost every butterfly you see.

    Abstract Conservationists and scientists throughout the world consider butterflies important indicators of broadscale factors affecting global biodiversity. And like other facets of biodiversity, declines in many butterfly populations appear related to human activities, and the potential of their extinction could jeopardize key ecosystem services. The regal fritillary (Argynnis idalia), a butterfly associated with tall‐ and mixed‐grass prairies in the United States, is a species currently being considered for federal protection under the Endangered Species Act. As with many butterflies, a paucity of data makes evidence‐based assessments of their population and distributional status difficult. Citizen science data provide one possible source of broadscale information about this species, but using these data is not simple because of spatial scaling and sampling bias problems. Here, we developed a model to analyze a data set from the citizen science program called the Fourth of July Butterfly Count (4JC) to make inferences about regal fritillary abundance in the Great Plains and Midwest regions of the United States. More specifically, we aimed to determine the extent to which grassland fragmentation, spring weather conditions, or other spatial factors were correlated with the intensity of use within 4JC survey areas. Our findings indicated that regal fritillaries used locations surrounded by grassland and with minimal forest cover. We included smoothing spline terms in our model, which indicated other sources of spatial structuring in these data. It is possible that these additional sources of variation could reflect variation in habitat quality. We also found that local averaged spring weather variables indicated that regal fritillary abundance varied over a wider range of precipitation conditions, but a narrower range of temperature conditions. Further analyses indicated that a systematic increase in temperature from climate change could lead to a pronounced northward shift in the regal fritillary's distribution. These findings have implications for the development of a recovery plan, since such a plan will need to outline a strategy that accounts for a range of patch sizes whose quality appears to vary spatially, as well as address numerous uncertainties about the future.

    Abstract Sickle cell disease (SCD) is the most common genetic disease in the US, affecting approximately 100,000 individuals. In SCD, genetically mutated hemoglobin (HbS) forms rigid polymers when deoxygenated, giving red blood cells a characteristic sickled shape. Increased blood viscosity and cell adhesion produce intermittent vaso-occlusion. The vaso-occlusive phenotype of SCD, which is marked by higher hemoglobin, manifests with frequent painful crises and is associated with a higher risk for developing acute chest syndrome. The hemolytic phenotype is characterized by lower baseline levels of hemoglobin and elevated markers of hemolysis. There are no reliable markers of vaso-occlusive crisis (VOC), ie, vital signs and laboratory tests are normal. After intravenous (IV) opiate titration, patient-controlled anesthesia (PCA) pumps are encouraged. Excess IV fluids have been associated with development of atelectasis, a risk factor for acute chest syndrome. Acute chest syndrome has clinical symptoms similar to pneumonia; these patients will develop progressive hypoxemia, acute respiratory distress syndrome, and death if exchange transfusion is not initiated.

    Abstract Purpose: To describe the spatial distribution and morphologic characteristics of macrophage-like cells called hyalocytes in the posterior vitreous cortex of a patient with unilateral partial posterior vitreous detachment (PVD) using coronal plane
    Observations: A 54-year-old male with sickle cell disease (HbSC genotype) presented with a partial PVD in one eye. Rendered volumes of a slab extending from 600 μm to 3 μm anterior to the inner limiting membrane (ILM) revealed hyperreflective foci in the detached posterior vitreous cortex suspended anterior to the macula, likely representing hyalocytes. In the fellow eye without PVD, hyperreflective foci were located 3 μm anterior to the ILM. The morphology of the cells in the eye with PVD varied between a ramified state with multiple elongated processes and a more activated state characterized by a plump cell body with fewer retracted processes. In the same anatomical location, the hyperreflective foci were 10-fold more numerous in the patient with vaso-occlusive disease than in an unaffected, age-matched control.
    Conclusions and importance: Direct, non-invasive, and label-free techniques of imaging cells at the vitreoretinal interface and within the vitreous body is an emerging field. The findings from this case report suggest that coronal plane

    Abstract Objective: Compare time to pain relief (minimum of a 13 mm and 30% reduction) during an Emergency Department (ED) visit among patients with sickle cell disease (SCD) experiencing severe pain associated with a vaso-occlusive episode who were randomized to receive either an individualized or weight-based pain protocol.
    Methods: A randomized controlled trial in two EDs. Adults with sickle cell disease. Research staff recorded pain scores every 30 min during an ED visit (up to 6 h in the ED) using a 0-100 mm visual analogue scale. Analysis included 122 visits, representing 49 patients (individualized: 61 visits, 25 patients; standard: 61 visits, 24 patients).
    Results: Pain reduction across 6-h was greater for the individualized compared to the standard protocol (protocol-by-time: p = .02; 6-h adjusted pain score comparison: Individualized: M = 29.2, SD = 38.8, standard: M = 45.3, SD = 35.6; p = .03, Cohen d = 0.43). Hazards models indicated a greater probability of 13 mm (HR = 1.54, 95% CI = 1.05, 2.27, p = .03) and 30% (HR = 1.71, 95% CI = 1.11, 2.63, p = .01) reduction in the individualized relative to the standard protocol.
    Conclusions: Patients who received treatment with an individualized protocol experienced a more rapid reduction in pain, including a 13 mm and 30% reduction in pain scores when compared to those that received weight-based dosing.

    Abstract The cause of death in people affected by sickle cell disease (SCD) is often challenging to define as prior studies have used retrospective or administrative data for analysis. We used a prospective longitudinal registry to assess mortality and clinical co-morbidities among subjects enrolled in the Sickle Cell Disease Implementation Consortium (SCDIC) registry. At enrollment, we collected the following data: patient-reported demographics, SCD phenotype, baseline laboratory values, comorbidities, and current medications. Subjects were followed for a median of 4.7 years before the present analysis. The relationship of clinical co-morbidities (at time of enrollment) to mortality was determined using survival analysis, adjusting for SCD phenotype and gender. There was a total of 2439 people with SCD enrolled in the SCDIC registry. One hundred and twenty-eight participants (5%) died during the observation period (2017-2022). Six people died from trauma and were excluded from further analysis. Proximate cause of death was unwitnessed in 17% of the deaths, but commonest causes of death include cardiac (18%), acute chest or respiratory failure (11%), sudden unexplained death (8%). Enrollment characteristics of the individuals who died (n = 122) were compared to those of survivors (n = 2317). Several co-morbidities at enrollment increased the odds of death on univariate analysis. All co-morbidities were included in a multivariable model. After backward elimination, iron overload, pulmonary hypertension, and depression, remained statistically significant predictors of the risk of death. SCD reduces life expectancy. Improved comprehensive and supportive care to prevent end-organ damage and address comorbidities is needed for this population.

    Abstract Many insects are in clear decline, with monarch butterflies (Danaus plexippus) drawing particular attention as a flagship species. It is well documented that, among migratory populations, numbers of overwintering monarchs have been falling across several decades, but trends among breeding monarchs are less clear. Here, we compile >135,000 monarch observations between 1993 and 2018 from the North American Butterfly Association's annual butterfly count to examine spatiotemporal patterns and potential drivers of adult monarch relative abundance trends across the entire breeding range in eastern and western North America. While the data revealed declines at some sites, particularly the US Northeast and parts of the Midwest, numbers in other areas, notably the US Southeast and Northwest, were unchanged or increasing, yielding a slightly positive overall trend across the species range. Negative impacts of agricultural glyphosate use appeared to be counterbalanced by positive effects of annual temperature, particularly in the US Midwest. Overall, our results suggest that population growth in summer is compensating for losses during the winter and that changing environmental variables have offsetting effects on mortality and/or reproduction. We suggest that density‐dependent reproductive compensation when lower numbers arrive each spring is currently able to maintain relatively stable breeding monarch numbers. However, we caution against complacency since accelerating climate change may bring growing threats. In addition, increases of summer monarchs in some regions, especially in California and in the south, may reflect replacement of migratory with resident populations. Nonetheless, it is perhaps reassuring that ubiquitous downward trends in summer monarch abundance are not evident.

    Abstract Background: National Heart Lung and Blood Institute guidelines for the treatment of vaso-occlusive crisis among people with sickle cell disease in the emergency department recommend assigning an emergency severity index of 2 at triage. However, patients with sickle cell disease often do not receive guideline-concordant care at triage. To address this gap, a decision support tool was developed, in the form of a text banner on the triage page in the electronic health record system, visible to triage nurses.
    Methods: A prospective quality improvement initiative was designed where the emergency severity index clinical decision support tool was deployed to a stratified random sample of emergency department triage nurses to receive the banner (n = 24) or not to receive the banner (n = 27), reminding them to assign the patient to emergency severity index category 2. The acceptability of the emergency severity index clinical decision support tool was evaluated with the Ottawa Acceptability of Decision Rules Instrument. Descriptive and bivariate (chi-square test) statistics were used to characterize the study's primary outcome, proportion of visits assigned an emergency severity index of 2 or higher. A generalized linear mixed model with clustering at the level of the triage nurse was performed to test the association between the banner intervention and triage practices.
    Results: A total of 384 ED visits were included for analysis. Before study initiation, the percentage of sickle cell disease patients' visits with the proper emergency severity index assignment at triage was 37.04%. After initiation, the proportion of sickle cell disease patients' visits with an emergency severity index of 2 or higher triaged by nurses in the intervention group was markedly higher in the intervention group than in the control group (64.95% vs 35.05%; χ
    Conclusion: Substantial improvements in triage guideline concordance were achieved and sustained without direct nursing education.
