Abstract Introduction Jazz DUET (Develop hypersomnia Understanding by Evaluating low-sodium oxybate Treatment) is a phase 4, prospective, multicenter, single-arm, multiple-cohort, open-label study (NCT05875974) evaluating the effectiveness of low-sodium oxybate (LXB, Xywav®) treatment on outcomes including sleep quality (using polysomnography [PSG] and self-reported questionnaires) in participants with narcolepsy or idiopathic hypersomnia. Data reported here are from the narcolepsy cohort. Methods DUET included a screening period (with 2-week washout for current oxybate users), an 8-day baseline (BL) period, a 2- to 8-week LXB titration period, a 2-week stable-dose period (SDP), an 8-day end-of-treatment (EOT) period, and a 2-week safety follow-up. Participants underwent nocturnal PSG (ad libitum protocol) at BL and EOT. The Karolinska Sleepiness Scale (KSS) was administered 90 minutes post-awakening from PSG to measure situational sleepiness (9-point scale; 1=“extremely alert” to 9=“extremely sleepy, can’t keep awake”). Participants completed an electronic sleep diary (eDiary) daily during the BL and EOT periods, including questions regarding nightly sleep patterns, total sleep time (TST), sleep quality (5-point scale; “very good” to “very poor”), and how rested/refreshed the participant felt upon awakening (5-point scale; “very well” to “not at all”). Completion of ≥5 eDiary days during the 8-day assessment before PSG visits was required for analysis. eDiary and KSS data were analyzed in the completer set (enrolled participants who were dosed with LXB and completed SDP and PSG at EOT). Results Fifty-five participants with narcolepsy (type 1, n=26; type 2, n=29) enrolled (completer set, n=34). Most were female (40/55; 73%) and White (44/55; 80%); mean (SD) age was 33.4 (12.9) years. Mean (SD) self-reported nocturnal TST at BL (n=32) and EOT (n=20) was 8.1 (1.6) and 8.3 (0.9) hours, respectively. The percent of participants rating their sleep quality as “very good”/“good” increased from 15.6% (BL) to 70.0% (EOT). The percent of participants with rested sleep (“very well”/“well”/“somewhat” rested) increased from 46.9% (BL) to 90.0% (EOT). Likewise, mean (SD) rating of self-reported sleepiness decreased from 5.1 (2.0) at BL to 3.8 (1.9) at EOT. Conclusion Following open-label LXB treatment, participants with narcolepsy reported improvements in sleep quality and feeling more rested and less sleepy upon awakening.

Abstract Introduction Jazz DUET (Develop hypersomnia Understanding by Evaluating low-sodium oxybate Treatment) is a phase 4, prospective, multicenter, single-arm, multiple-cohort, open-label study (NCT05875974) evaluating effectiveness of low-sodium oxybate (LXB, Xywav®) treatment on outcomes including polysomnography (PSG)-based sleep architecture in participants with idiopathic hypersomnia or narcolepsy (type 1 [NT1] or 2 [NT2]). Methods DUET included a screening period (2-week washout for current oxybate users), 8-day baseline (BL) period, 2- to 8-week LXB titration period, 2-week stable-dose period (SDP), 8-day end-of-treatment period (EOT), and 2-week safety follow-up. Participants underwent nocturnal PSG (ad libitum protocol) at BL and EOT. PSGs were scheduled to allow a minimum of 10 hours in bed, unless the participant naturally awakened earlier; bedtime was determined by habitual bedtime. PSG recordings were centrally scored. Data were analyzed for participants in the narcolepsy cohort completer set. Total shifts from deeper to lighter sleep stages was defined as N1/N2/N3/REM to wake and N2/N3/REM to N1. Key secondary endpoints (total stage shifts, N3 duration) were controlled for multiplicity with sequential testing; other P-values are considered nominal. Results Fifty-five participants with narcolepsy enrolled (NT1, n=26; NT2, n=29); 34 completed the study (NT1, n=16; NT2, n=18). Most were female (73%) and White (80%) (mean±SD age, 33.4±12.9 years). Mean±SD total sleep time (TST) at BL/EOT was 453.2±80.1/452.4±70.0 minutes (LSM change [95% CI]: –0.78 [–23.7, 22.1]; P=.9451). Mean±SD number of total shifts from deeper to lighter sleep stages at BL/EOT was 54.6±28.0/41.6±25.6 (LSM [95% CI]: –13.1 [–19.0, –7.1]; P<.0001 [controlled for multiplicity]). Mean±SD time spent in N1 at BL/EOT was 45.3±28.4/37.2±25.2 minutes (LSM [95% CI]: –8.1 [–14.9, –1.4]; P=.0196), % of stage was 10.4%/8.2% (P=.0037); in N2 was 241.8±61.2/243.3±76.1 minutes (LSM [95% CI]: 1.5 [–23.6, 26.6]; P=.9040), 53.1%/53.2% (P=.9869); in N3 was 61.1±34.8/106.1±69.5 minutes (LSM [95% CI]: 45.0 [27.0, 63.0]; P<.0001 [controlled for multiplicity]), 13.7%/24.0% (P<.0001); and in REM was 105.0±42.7/65.8±33.1 minutes (LSM [95% CI]: –39.2 [–50.8, –27.5]; P<.0001), 22.8%/14.7% (P<.0001). Conclusion Participants with narcolepsy taking open-label LXB showed negligible change in TST and N2, increased N3, decreased N1 and REM, and fewer shifts from deeper to lighter stages of sleep.

Atopic dermatitis affects 20% to 25% of children and has significant impact on quality of life of patients and families. Recent studies of the pathogenesis of AD highlight the interplay between a defective skin barrier, immune dysfunction, and the cutaneous microbiome. Standard of care for AD treatment includes topical corticosteroids for active disease and moisturization to repair the barrier defect. Emerging treatments include dupilumab and Janus kinase (JAK) inhibitors. Reduction of triggers and proactive treatment with topical corticosteroids and/or topical calcineurin inhibitors can reduce flares. Treatment plans should be clear and as simple as possible to maximize adherence.

BACKGROUND: Thresholds to define prognosis with hs-cTnI (high-sensitivity cardiac troponin I) have not been systematically addressed in wild-type transthyretin amyloid cardiomyopathy, in part because of the multiplicity of hs-cTnI assays. The aims of this study were: first, to assess the prognostic performance of hs-cTnI measured with different assays in patients with wild-type transthyretin amyloid cardiomyopathy and, second, to identify assay-specific hs-cTnI thresholds for prognosis that could be integrated into staging systems for risk stratification. METHODS: Observational multicenter study of stable wild-type transthyretin amyloid cardiomyopathy patients from different cohorts using the Abbott Architect Stat hs-cTnI assay and the Beckman Coulter Access hs-cTnI assay (testing cohorts) and the Siemens Centaur XPT hs-cTnI assay (validation cohort). Outcome was all-cause mortality. RESULTS: In the Abbott cohort (n=136; median follow-up 22 [13–41] months; 31 [23%] deaths) and Beckman cohort (n=98; median follow-up 19 [12–28] months; 16 [16%] deaths), natural log-transformed hs-cTnI was an independent predictor of mortality (age- and sex-adjusted hazard ratio, 1.62 [95% CI, 1.11–2.35]; P =0.012 and 2.47 [95% CI, 1.48–4.14]; P <0.001, respectively). The best hs-cTnI threshold for 18-month mortality of the combined Abbott/Beckman cohorts (n=234) was 81 ng/L, rounded to 80 ng/L for simplicity of clinical use. A 2-variable staging system (based on the Mayo Clinic system) using hs-cTnI (>80 ng/L) and NPs (natriuretic peptides; NT-proBNP [N-terminal pro-B-type natriuretic peptide] >3000 ng/L or BNP [B-type natriuretic peptide] >250 ng/L) identified 3 groups with progressively worse prognosis. The staging system (using hs-cTnI >80 ng/L and NT-proBNP>3000 ng/L) was then applied to an independent cohort evaluated with the hs-cTnI Siemens assay (n=345, median follow-up 32 [24-42] months, 119 [34%] deaths). The significant differences between the groups were maintained. CONCLUSIONS: In patients with wild-type transthyretin amyloid cardiomyopathy, hs-cTnI is a strong and independent predictor of mortality. A threshold of hs-cTnI of 80 ng/L for these 3 assays provides effective risk stratification alone and in a staging system with NP.

Abstract RATIONALE: The diagnosis of Pulmonary Embolism (PE) is associated with high mortality and morbidity. In patients with cancer, high-risk pulmonary emboli further escalate these risks. Ensuring access to the necessary resources for appropriate intervention is crucial for improving patient outcomes. However, the resource-intensive nature of managing multiple life-threatening conditions can create barriers for certain demographic populations, leading to disparities in outcomes. To address this issue, we explored mortality trends among diverse groups based on gender, ethnicity, and geographical background in the United States from 1999-2000. METHODS: We obtained mortality data from death certificate queries in the Centers for Disease Control and Prevention Wide-range Online Data for Epidemiologic Research database. Queries included all decedents with the underlying cause of death being PE (I26) in patients with a diagnosis of cancer (C00 – C97). Age-adjusted mortality rates (AAMR) per 100,000 people were compared across demographic populations, and 95% Confidence Intervals were standardized to the year 2000. Log-linear regression models were utilized to assess temporal mortality shifts and calculate annual percentage change (APC) from 1999 to 2020. RESULTS: A total of 179483 PE-related deaths was reported in patients with cancer. The AAMR increased from 2.14 [2.08-2.19] in 1999 to 3.05 [3.00-3.11] in 2020. The cumulative AAMR was 2.42 [2.41-2.43] with an average APC of +1.56% (p&lt;0.001). The mortality rate accelerated following the year 2016, with the years prior having an APC of +0.69%, (p&lt;0.001) and the years following having an APC +5.33% (p&lt;0.001). A higher mortality was observed in males (AAMR 2.71 [2.69-2.73]) than females (2.20 [2.18-2.21]), in rural communities (AAMR 2.50 [2.47-2.53]) compared to urban communities (AAMR 2.38 [2.37-2.40]), and in non-Hispanic (AAMR 2.48 [2.47-2.49]) populations over Hispanic populations (AAMR 1.45 [1.42-1.48]). Mortality was highest in the Black population (AAMR 3.65 [3.60-3.69]), followed by White population (AAMR 2.33 [2.32-2.34]), American Natives (AAMR 1.43 [1.33-1.54]), and Asian (AAMR 1.04 [1.00-1.08]). Geographically, Midwest (AAMR 2.58 [2.56-2.61]) had the highest mortality while the South (AAMR 2.26 [2.24-2.28]) had the lowest mortality. CONCLUSIONS: We identified significant disparities in mortality related to pulmonary embolism (PE) among cancer patients across different demographic populations. Further investigation into these healthcare inequities is essential for addressing the disparities affecting various groups.

Abstract Rationale: Since the initial descriptions of pulmonary arterial hypertension (PAH), there has been a significant increase in PAH diagnoses among the geriatric population. Studies suggest that older PAH patients exhibit unique hemodynamic profiles and treatment responses. We hypothesized that patients ≥80 years old would have a unique clinical profile and worse outcomes. Methods: The Pulmonary Hypertension Association Registry (PHAR) is a prospective cohort of PAH and chronic thromboembolic pulmonary hypertension (CTEPH) patients new to care at a Pulmonary Hypertension Care Center in the US. Individuals &lt;18 years of age and those with CTEPH were excluded. Clinical data, quality of life measures, and functional capacity were recorded at time of enrollment and at follow up visits. Octogenarians were defined as those ≥80 years old and non-octogenarians as &lt;80 years old. Associations between age subgroups with the change in six-minute walk distance (6MWD), and worsened WHO functional class (WHO FC) at the next visit, and time to all-cause mortality were assessed using linear, binomial, and Cox regression, respectively. Results: The study sample included 87 PAH octogenarian patients and 2,583 non-octogenarian patients at enrollment. The Table shows that octogenarian PAH patients were of similar sex and race distribution as others, but had lower body mass index. Octogenarians were more likely to have idiopathic or CTD-related PAH, and differed from younger patients in terms of several sociodemographic variables. PAH treatment, WHO FC, quality of life, and hemodynamic also differed between the groups. Octogenarians had a lower change in 6MWD (-26m, 95%CI -52 – -2, p = 0.066) and worse WHO FC (2.0, 95%CI 1.1 – 3.8, p = 0.038) over time compared to other adults after adjustment for sex, BMI, PAH etiology, annual income, marital status, right atrial pressure, mean pulmonary artery pressure, and PAH treatment. Octogenarians had an increased risk of death compared to younger adults (hazard ratio 1.7, 95%CI 1.1 – 2.6, p = 0.022) after adjustment for covariates. Conclusions: While the eldest PAH patients may have some comparable features to younger patients, they are different in a variety of socioeconomic variables, disease type, hemodynamics, and number of PAH therapies. The eldest PAH patients demonstrate worse exercise and functional capacity with time and a 70% increased risk of death compared to younger patients. Further studies are needed to better characterize PAH in the elderly, as this may lead to more effective treatments and enhanced quality of life.

AbstractA diverse workforce in emergency medicine (EM) aims to improve patient care by addressing racism in health care, increasing representation in medicine, and improving the quality of training for all residents. Many EM residency programs have launched recruitment efforts to attract residents from diverse backgrounds. However, recruitment efforts only represent the first step in building a culturally responsible workforce. Trainees who are underrepresented in medicine must be welcomed into an inclusive training environment that has been thoughtfully constructed before they arrive. This type of supportive environment can be achieved by shifting away from majority‐serving ideals and building an informed infrastructure that functions to help all trainees succeed. We expand upon challenges and areas of opportunity at the individual, departmental, and institutional levels and describe common pitfalls when trying to create inclusive spaces for residents including lack of vision alignment, inadequate financial investment, and performative allyship. We also propose strategies that focus specifically on actionable changes that residency program, departmental, and institutional leadership can implement to mitigate these challenges.

Background The Woven EndoBridge (WEB) device is a prevalent treatment for intracranial aneurysms. While many studies have assessed the obliteration rate post-WEB embolization, few have focused on long-term outcomes in partially thrombosed aneurysms. Objective To assess whether partially thrombosed aneurysms are at higher risk of recurrence or retreatment following WEB embolization compared with non-thrombosed aneurysms. Methods We evaluated data from 22 academic institutions, focusing on previously untreated cerebral aneurysms treated with the WEB device. Logistic regression was utilized to analyze factors predicting long-term aneurysm obliteration and retreatment necessity. Results Among 1303 patients, 26 presented with a partially thrombosed aneurysm. In the partially thrombosed group, the mean aneurysm maximal diameter was 10.7±4 mm with a neck ratio of 1.99±1.19 mm, larger than in the control group where the mean aneurysm maximal diameter was 6.81±2.37 mm with a neck ratio of 1.64±0.51 mm (P<0.001 for both maximal diameter and neck ratio). At the final follow-up, partially thrombosed aneurysms treated by the WEB device had a 38.5% retreatment rate, compared with 7.0% for non-thrombosed aneurysms (P<0.001). Among partially thrombosed aneurysms, the Raymond-Roy type IIIa/b occlusion rate was higher (38.5% vs 9.9%, P<0.001). On multivariate analysis, partially thrombosed aneurysms compared with non-thrombosed aneurysms had an increased rate of retreatment (OR 3.64, 95% CI 1.28 to 10.1). Conclusion Partially thrombosed aneurysms are associated with a poorer occlusion rate and a higher rate of retreatment following WEB embolization. For partially thrombosed aneurysms, the WEB device appears suboptimal as a first-line treatment, and therefore alternative techniques should be prioritized.

We here present evidence-based guidelines for the pharmacological treatment of migraine. These guidelines, created by the Italian Society for the Study of Headache and the International Headache Society, aim to offer clear, actionable recommendations to healthcare professionals. They incorporate evidence-based recommendations from randomized controlled trials and expert-based opinions. The guidelines follow the GRADE approach for assessing the quality of evidence. The guideline development involved a systematic review of literature across multiple databases, adherence to Cochrane review methods, and a structured framework for data extraction and interpretation. Although the guidelines provide a robust foundation for migraine treatment, they also highlight gaps in current research, such as the paucity of head-to-head drug comparisons and the need for long-term outcome studies. These guidelines serve as a resource to standardize migraine treatment and promote high-quality care across different healthcare settings.
