Abstract Introduction Sleep inertia (characterized by profound difficulty waking up with grogginess, disorientation, and cognitive impairment immediately after awakening) is a core idiopathic hypersomnia symptom and may also be experienced by individuals with narcolepsy. Sleep inertia in individuals with narcolepsy is not well studied. This post-hoc analysis of the DUET study (NCT05875974) evaluated sleep inertia in narcolepsy type 1 (NT1) and narcolepsy type 2 (NT2) subgroups of the DUET narcolepsy cohort. Methods DUET was a phase 4, prospective, open-label study with baseline (BL), titration/optimization, stable-dose, and end-of-treatment (EOT) periods. Exploratory outcomes included Psychomotor Vigilance Test (PVT; objective performance impairment) and Karolinska Sleepiness Scale (KSS; subjective sleepiness); both administered at BL and EOT, in the morning after overnight polysomnogram. The 10-minute PVT was completed at 10, 40, and 90 minutes after awakening. The KSS, a single-item, 9-point scale, was completed upon awakening and immediately before and after the PVT assessments. Separate nonlinear, mixed-effects regression models were applied to PVT lapses and KSS ratings to estimate objective and subjective sleep inertia magnitudes, respectively, for NT1 and NT2, along with sleep inertia dissipation time constants for the overall cohort. Treatment-emergent adverse events (TEAEs) were assessed. Results Of 55 enrolled participants with narcolepsy, 26 and 29 had NT1 and NT2, respectively. Most (NT1/NT2) were female (73.1%/72.4%) and White (73.1%/86.2%); 16/26 and 18/29 completed the study. Based on PVT lapses, objective sleep inertia ±SE (NT1/NT2) at BL was 33.1±6.2/14.9±3.2, and at EOT was 8.3±1.7/3.2±1.1 (BL-to-EOT changes [95% CI]: −24.8 [−35.5, −14.1] and −11.8 [−17.4, −6.1]). Based on KSS ratings, subjective sleep inertia ±SE (NT1/NT2) at BL was 1.1±0.6/1.1±0.5, and at EOT was 0.8±0.5/1.3±0.5 (BL-to-EOT changes [95% CI]: −0.3 [−1.9, 1.2] and 0.2 [−1.3, 1.6]). Sleep inertia dissipation time constants ±SE were 1.6±0.3h (PVT) and 0.4±0.1h (KSS) for the overall cohort. TEAEs were consistent with the known LXB safety profile. Conclusion Participants with narcolepsy, especially NT1, demonstrated objective sleep inertia at BL. Participants with NT1 or NT2 showed substantial improvements in objective sleep inertia with LXB treatment. Support (if any) Jazz Pharmaceuticals

Importance Seizure-induced brain injury is central to the treatment urgency of new-onset refractory status epilepticus (NORSE). Identifying biomarkers that reflect ongoing neuronal damage could inform therapeutic timing and improve outcomes. Objective To quantify acute brain injury in patients with cryptogenic NORSE (cNORSE), etiology-defined status epilepticus (eSE), and chronic epilepsy. Design, Setting, and Participants This was an international cross-sectional study conducted between 2013 and 2025. Patients were enrolled at 36 hospitals in the US, 2 in Canada, and 1 in Italy, France, and Belgium. Patients with cNORSE and eSE for which biological samples were obtained during ongoing seizure activity were enrolled in the study. Comparison groups without status epilepticus comprised individuals with chronic epilepsy and healthy participants. None were excluded. Exposures Neurofilament light chain (NfL) and S100-beta (S100B) protein concentrations in serum and cerebrospinal fluid (CSF). Main Outcomes and Measures Degree of neuronal and glial damage, indexed by NfL and S100B levels, and their association with short-term functional outcomes. Results A total of 78 patients with cNORSE (mean [95% CI] age, 37 [30-41] years; 44 female [56%]) and 2 independent cohorts of 211 patients (mean [95% CI] age, 69 [66-71] years; 128 female [61%]) and 73 patients (mean [95% CI] age, 56 [45-65] years; 39 male [53%]) with eSE were included. NfL concentrations were markedly elevated in cNORSE—approximately 10-fold higher in CSF and 4-fold higher in serum—compared with the eSE cohorts (CSF: median [IQR], 6408 [1503-22 963] pg/mL compared with 694 [219-2389] pg/mL; serum: median [IQR], 231 [99-855] pg/mL compared with 55 [20-135] pg/mL; P <.001). Serum NfL levels were nearly 20-fold higher in cNORSE than in the cohort with epilepsy and in healthy controls (median [IQR], 11 [7-19 ] and 7 [5-14 ] pg/mL, respectively). Serum and CSF NfL levels were strongly correlated (Spearman ρ = 0.75; P < .001) and rose sharply between week 1 (median [IQR], 101 [51-137] pg/mL), week 2 (median [IQR], 197 [117-324] pg/mL), and week 3 (median [IQR], 598 [163-1000] pg/mL) after onset ( P < .001). In contrast, S100B concentrations did not differ between groups and showed no consistent temporal pattern. NfL discriminated cNORSE from eSE (area under the receiver operating characteristic curve [AUROC], 0.79; 95% CI, 0.68-0.90) and from cohorts without status epilepticus (AUROC, 0.99; 95% CI, 0.78-1.00). Higher serum NfL was independently associated with poor functional outcome at discharge (Glasgow Outcome Scale extended score, 1-4; odds ratio, 1.01; 95% CI, 1.00-1.03; P = .03). Conclusions and Relevance Results of this cross-sectional study suggest that acute neuroaxonal injury, as reflected by elevated NfL levels, was substantially greater in cNORSE than in the cohorts with eSE and in controls without status epilepticus. The rapid early rise in NfL highlights a narrow therapeutic window, emphasizing the need for prompt, effective, and potentially neuroprotective interventions in cNORSE.

BACKGROUND: Burnout remains prevalent among anesthesiology residents. Contributing workplace factors include limited control over scheduling, unpredictable hours, critical patient care needs, and other residency challenges. The Family Anesthesia Experience (FAX) is a program designed to educate residents and their support persons on wellness and residency demands. The focus of this multisite study was to evaluate the impact of FAX on first year clinical anesthesiology (CA1, ie, PGY2s) residents’ wellness. METHODS: This was a prospective evaluation study involving 15 US anesthesiology residency programs, 13 of which completed FAX. CA1 wellness was evaluated through surveys assessing perceived stress as the primary outcome, with exploratory outcomes including burnout, depression, psychological wellness, and social support. Additionally, changes in support persons’ understanding and knowledge of residency demands were tracked over time. The study included a historical control group of 302 CA1s (2019-2021) who did not participate in FAX, and an intervention group of 88 CA1s that participated in FAX (2021-2022). Statistical analyses compared changes in metrics between groups using linear mixed models and generalized linear models. RESULTS: Significant reductions in perceived stress were observed in the intervention group at 6 months post-FAX (mean change = –2.14, 95% CI, –3.95 to –0.34; P = .021, effect size = 0.58) relative to the control group, but there was no sustained difference at 12 months. Compared to the control support persons, intervention support persons reported increased understanding of residency demands, with significant improvements at 6 (mean change = 2.80, 95% CI, 1.12–4.48; P = .001, effect size = 0.77) and 12 (mean change = 2.59, 95% CI, 0.12–5.05; P = .039, effect size = 0.71) months. Improvement in support persons’ understanding did not predict changes in CA1 wellness outcomes. First generation physician residents reported lower family support at baseline but showed significant improvements in family support at 6 months (mean change = 3.05 points; 95% CI, 0.25–5.84; P = .033; effect size = 1.23) compared to their non first generation peers. CONCLUSIONS: FAX participation was associated with reduced perceived stress in residents up to 6 months post-intervention. First generation physicians experienced greater improvements in perceived family support compared to their non first generation peers. Our findings suggest that resident wellness may be enhanced by engaging both residents and their support persons in an educational wellness program that outlines the professional expectations and demands of anesthesiology residency training.

Abstract Purpose: In RET-rearranged non–small cell lung cancer (NSCLC), treatment options after first-generation selective RET inhibitors (SRI) are limited, and the value of SRI retreatment remains unclear. This study evaluates outcomes of SRI retreatment. Experimental Design: This multicenter retrospective study included patients with advanced RET-rearranged NSCLC who received ≥2 SRI-based therapy lines. Of 411 SRI-treated patients, 41 (10%) underwent SRI retreatment. Outcomes included objective response rate (ORR), progression-free survival (PFS), 6-month PFS, time to treatment failure, adverse events (AE). Results: Among 41 patients, 14 (34%) discontinued the initial SRI because of toxicity and 27 (66%) because of progression. After discontinuation for toxicity, all switched to an alternate SRI, achieving an ORR of 67%, median PFS of 9.9 months, and 6-month PFS of 80.3%. AEs reoccurred in nine patients (64%), with grade ≥3 AEs in 3 (21%) who switched at full dose. Among patients who discontinued because of progression, SRI monotherapy (n = 13) achieved an ORR of 23%, median PFS of 7 months, and 6-month PFS of 61.5%. Benefit was observed in patients with brain-only or oligoprogressive disease or dose reduction on first SRI. Combination therapy (n = 14; targeted agents, n = 11; chemotherapy, n = 3) achieved an ORR of 39%, median PFS of 4 months, and 6-month PFS of 27.3%. Conclusions: Same-class SRI switch after toxicity is feasible and clinically active but warrants cautious, dose-adjusted switching to mitigate toxicities. The efficacy of SRI rechallenge after progression seems limited overall. However, selected patients, such as those with brain-only or oligoprogressive disease, may derive benefit.

PURPOSE Chronic myelomonocytic leukemia (CMML) is a rare myeloid neoplasm characterized by clinical heterogeneity and is associated with poor outcomes. To date, limited molecular information has been incorporated into disease classification and risk stratification. We aimed to integrate genomic features into the clinical decision-making process for CMML. PATIENTS AND METHODS We analyzed a retrospective cohort of 3013 patients with CMML (training set) and a prospective population of 516 patients (validation set). Using an innovative framework for multimodal data analysis, we developed molecular-based disease taxonomy and prognostication. RESULTS Unsupervised clustering identified nine entities with distinct genomic features and outcomes ( P < .001), including splicing machinery, transcription factors, signal transduction and tyrosine kinase pathways aberrations, and high-risk molecular signatures. Notably, 15% of patients showed molecular/clinical overlap with other myeloid neoplasms. We integrated molecular and clinical information to build the international CMML Prognostic Scoring System (iCPSS), incorporating mutations in nine genes together with hematologic parameters and cytogenetic abnormalities. The iCPSS identified five groups with distinct probability of overall and leukemia-free survival in both training and validation cohorts ( P < .001), outperforming existing prognostic models. Importantly, 55% of patients were reassigned to higher or lower risk groups by the iCPSS. Decision analysis demonstrated that iCPSS could refine the optimal timing of allogeneic transplantation at the individual level; compared with conventional prognostic tools, iCPSS-based decision modeling changed transplantation strategy in 31% of cases, resulting in a significant gain-in-life expectancy for eligible patient population ( P < .001). A federated learning platform was implemented to enable continuous, privacy-preserving model update across multiple centers. CONCLUSION Molecular information improves CMML classification and prognostication, supports more effective clinical decision making, and potentially refines the design of clinical trials.

ABSTRACT Introduction and Methods Cancer therapy–related cardiac dysfunction (CTRCD) is a well established and potentially life‐threatening complication of contemporary oncologic treatment. Although comprehensive cardio‐oncology guidelines have been developed, their integration into routine hematology and oncology practice remains inconsistent. This consensus statement, developed by a multidisciplinary panel of cardio‐oncology experts, aims to provide practical, case‐based guidance to help oncology providers recognize, assess, and manage CTRCD across a spectrum of malignancies and cardiovascular presentations. Clinical Scenarios and Discussion We present representative clinical scenarios that illustrate real‐world challenges in cardio‐oncology and apply evidence‐based recommendations from current guidelines, including those from the European Society of Cardiology (ESC) and the International Cardio‐Oncology Society (ICOS)—to support informed decision‐making. Key areas of focus include baseline cardiovascular risk stratification prior to initiating potentially cardiotoxic therapies, with an emphasis on biomarker and imaging surveillance strategies tailored to individual risk profiles. Also, this document outlines the application of guideline‐directed medical therapy (GDMT) for cancer patients with heart failure. Conclusion By offering a structured, user‐friendly framework, this document seeks to bridge the implementation gap between oncology and cardiology disciplines. Our goal is to equip oncology providers with accessible tools that facilitate early recognition, consistent surveillance, and timely referral, thereby preserving cancer treatment intensity while minimizing cardiovascular morbidity.

OBJECTIVE: A definition of refractory septic shock is necessary to guide diagnosis, management, prognostication, research, and future guidelines for this most severe form of the disease. We sought to achieve consensus on clinical criteria that would be used to define refractory septic shock. DESIGN: Review of literature, expert panel position statements, and Delphi rounds with an international expert group. SETTING: Consensus was defined as having at least 75% of panellists in agreement or disagreement on the three highest or lowest levels of a 7-point Likert scale or based on responses to single- or multiple-choice questions, respectively. SUBJECTS: A panel of multinational, multiprofessional and multidisciplinary critical care experts assembled by the Society of Critical Care Medicine and the European Society of Intensive Care Medicine (57 invitations and 56 participants). MEASUREMENTS AND MAIN RESULTS: A five-round Delphi process was conducted for consensus and stability. The steering committee proposed 34 statements, and five of them were rejected by panel experts after round 2. Among 29 statements selected from eight domains, consensus was reached for 13. The panel agreed on the need for a comprehensive consensus set of clinical criteria for refractory septic shock. Markers of organ dysfunction (75%, 2 rounds), tissue perfusion (91.1%, 2 rounds) including lactate (94.6%, 2 rounds) and capillary refill time (76.8%, 2 rounds), assessment of fluid-responsiveness after initial resuscitation (92.9%, 5 rounds), and use of vasoactive drugs at norepinephrine equivalents greater than 0.5 µg/kg/min (75.0%, 3 rounds), were selected as clinical criteria of refractory septic shock. The use of critical care ultrasound (CCUS) (92.9%, 3 rounds) was the single diagnostic modality that reached a consensus-based agreement. CONCLUSIONS: A consensus for 13 criteria to frame the definition of refractory septic shock was reached. Refractory septic shock is characterised by persistently elevated lactate concentrations and or prolonged capillary refill time in patients with septic shock who are fluid unresponsive, require a norepinephrine base equivalent dose greater than 0.5 micrograms per kilogram per minute, and undergo CCUS assessment when mixed shock is suspected.

Abstract Lentigo maligna (LM) is a subtype of cutaneous melanoma in situ that develops on chronically sun‐damaged skin in elderly individuals. Its diagnosis and management remain challenging due to its slow progression, frequent occurrence on cosmetically sensitive areas in frail individuals, and tendency for subclinical peripheral extension. Despite its potential for invasive transformation, the natural history of LM remains incompletely understood and evidence‐based management strategies for this specific entity remain limited. This work aims to bridge the gap between scarce high‐quality evidence and the clinicians' need for practical guidance on LM management by formulating evidence‐based and expert consensus‐driven recommendations for diagnosis, treatment and follow‐up. Under the coordination of the International Dermoscopy Society, a global, multidisciplinary consortium of 53 experts—including dermatologists, dermato‐oncologists, dermatologic surgeons, radiologists, radiotherapists, pathologists and epidemiologists—formulated recommendations through structured consensus, informed by a comprehensive review of current scientific evidence and clinical practice standards. Optimal management of LM requires accurate diagnosis and individualized treatment planning. Non‐invasive skin imaging techniques, especially dermoscopy and reflectance confocal microscopy, aid in diagnosis, biopsy orientation, lesion delineation and post‐treatment monitoring. Multiple partial biopsies help confirm diagnosis and rule out invasion. Complete surgical excision remains the first treatment option. No definitive safety margins can be recommended for standard surgery; margin‐controlled techniques are preferable for large or ill‐defined lesions. Topical imiquimod and radiotherapy are effective alternatives where surgery is unsuitable. Topical imiquimod is useful as primary, adjuvant or neoadjuvant therapy. Blind destructive methods should be avoided. Close clinical and imaging follow‐up is needed. Patient‐centred care, shared decision‐making, and a multidisciplinary approach are critical for optimal outcomes. These international consensus recommendations summarize current best practices for LM management, offering practical, evidence‐informed guidance to clinicians while acknowledging the potential of future research in refining these conclusions.
