Abstract Background Time spent awaiting discharge after the acute need for hospitalization has resolved is an important potential contributor to hospital length of stay (LOS). Objective To measure the prevalence, impact, and context of patients who remain hospitalized for prolonged periods after completion of acute care needs. Design, Setting, and Participants We conducted a cross‐sectional “point‐in‐time” survey at each of 15 academic US hospitals using a structured data collection tool with on‐service acute care medicine attending physicians in fall 2022. Main Outcomes and Measures Primary outcomes were number and percentage of patients considered “medically ready for discharge” with emphasis on those who had experienced a “major barrier to discharge” (medically ready for discharge for ≥1 week). Estimated LOS attributable to major discharge barriers, contributory discharge needs, and associated hospital characteristics were measured. Results Of 1928 patients sampled, 35.0% ( n = 674) were medically ready for discharge including 9.8% ( n = 189) with major discharge barriers. Many patients with major discharge barriers (44.4%; 84/189) had spent a month or longer medically ready for discharge and commonly (84.1%; 159/189) required some form of skilled therapy or daily living support services for discharge. Higher proportions of patients experiencing major discharge barriers were found in public versus private, nonprofit hospitals (12.0% vs. 7.2%; p = .001) and county versus noncounty hospitals (14.5% vs. 8.8%; p = .002). Conclusions Patients experience major discharge barriers in many US hospitals and spend prolonged time awaiting discharge, often for support needs that may be outside of clinician control.

Abstract Primary aldosteronism (PA) is the most common cause of secondary hypertension and is associated with increased morbidity and mortality when compared with blood pressure–matched cases of primary hypertension. Current limitations in patient care stem from delayed recognition of the condition, limited access to key diagnostic procedures, and lack of a definitive therapy option for nonsurgical candidates. However, several recent advances have the potential to address these barriers to optimal care. From a diagnostic perspective, machine-learning algorithms have shown promise in the prediction of PA subtypes, while the development of noninvasive alternatives to adrenal vein sampling (including molecular positron emission tomography imaging) has made accurate localization of functioning adrenal nodules possible. In parallel, more selective approaches to targeting the causative aldosterone-producing adrenal adenoma/nodule (APA/APN) have emerged with the advent of partial adrenalectomy or precision ablation. Additionally, the development of novel pharmacological agents may help to mitigate off-target effects of aldosterone and improve clinical efficacy and outcomes. Here, we consider how each of these innovations might change our approach to the patient with PA, to allow more tailored investigation and treatment plans, with corresponding improvement in clinical outcomes and resource utilization, for this highly prevalent disorder.

The NCCN Guidelines for Survivorship are intended to help healthcare professionals address the complex and varied needs of cancer survivors. The NCCN Guidelines provide screening, evaluation, and treatment recommendations for psychosocial and physical problems resulting from adult-onset cancer and its treatment; recommendations to help promote healthy behaviors and immunizations in survivors; and a framework for care coordination. These NCCN Guidelines Insights summarize recent guideline updates and panel discussions pertaining to sleep disorders, fatigue, and cognitive function in cancer survivors.

Abstract Background Immune checkpoint inhibitor combined with platinum‐etoposide is the standard first‐line therapy for patients with extensive‐stage small cell lung cancer (ES‐SCLC). The phase 3 clinical trials that led to the approval of chemoimmunotherapy in ES‐SCLC excluded patients who had an Eastern Cooperative Group (ECOG) performance status (PS) of 2–3. Therefore, data on the efficacy of chemoimmunotherapy in patients with an ECOG PS of 2–3 are limited. Methods A retrospective analysis was performed on patients diagnosed with ES‐SCLC who received chemoimmunotherapy (atezolizumab or durvalumab) within the Mayo Clinic Health System between January 2016 and January 2021. The objective of this study was to compare the overall survival (OS), progression‐free survival (PFS), and best clinical response to therapy in patients with an ECOG PS of 0–1 vs. patients with an ECOG PS of 2–3 who received chemoimmunotherapy for newly diagnosed ES‐SCLC. Results In total, 82 patients were included in the study. The mean ± standard deviation age was 68.1 ± 8.3 years. Of these, 56 patients were identified with an ECOG PS of 0–1, and 26 patients were identified with an ECOG PS of 2–3. The median PFS was similar regardless of ECOG PS (5.8 months [95% CI, 4.3–6.0 months] in the ECOG PS 0–1 group vs. 4.1 months [95% CI, 3.8–6.9 months] in the ECOG PS 2–3; p = .2994). The median OS was also similar regardless of ECOG PS (10.6 months [95% CI, 8.4–13.4 months] in the ECOG PS 0–1 group vs. 9.3 months [95% CI, 4.9–12.8 months]; p = .2718) in the ECOG PS 2‐3 group. Conclusions The study results demonstrated no significant difference in PFS or OS among the ECOG PS 2–3 and ECOG PS 0–1 groups. Therefore, chemoimmunotherapy should be considered for patients who have ES‐SCLC with an ECOG PS of 2–3.

ImportanceCurrent olfactory neuroblastoma (ONB) staging systems inadequately delineate locally advanced tumors, do not incorporate tumor grade, and poorly estimate survival and recurrence.ObjectiveThe primary aims of this study were to (1) examine the clinical covariates associated with survival and recurrence of ONB in a modern-era multicenter cohort and (2) incorporate Hyams tumor grade into existing staging systems to assess its ability to estimate survival and recurrence.Design, Setting, and ParticipantsThis retrospective, multicenter, case-control study included patients with ONB who underwent treatment between January 1, 2005, and December 31, 2021, at 9 North American academic medical centers.InterventionStandard-of-care ONB treatment.Main Outcome and MeasuresThe main outcomes were overall survival (OS), disease-free survival (DFS), and disease-specific survival (DSS) as C statistics for model prediction.ResultsA total of 256 patients with ONB (mean [SD] age, 52.0 [15.6] years; 115 female [44.9%]; 141 male [55.1%]) were included. The 5-year rate for OS was 83.5% (95% CI, 78.3%-89.1%); for DFS, 70.8% (95% CI, 64.3%-78.0%); and for DSS, 94.1% (95% CI, 90.5%-97.8%). On multivariable analysis, age, American Joint Committee on Cancer (AJCC) stage, involvement of bilateral maxillary sinuses, and positive margins were associated with OS. Only AJCC stage was associated with DFS. Only N stage was associated with DSS. When assessing the ability of staging systems to estimate OS, the best-performing model was the novel modification of the Dulguerov system (C statistic, 0.66; 95% CI, 0.59-0.76), and the Kadish system performed most poorly (C statistic, 0.57; 95% CI, 0.50-0.63). Regarding estimation of DFS, the modified Kadish system performed most poorly (C statistic, 0.55; 95% CI, 0.51-0.66), while the novel modification of the AJCC system performed the best (C statistic, 0.70; 95% CI, 0.66-0.80). Regarding estimation of DSS, the modified Kadish system was the best-performing model (C statistic, 0.79; 95% CI, 0.70-0.94), and the unmodified Kadish performed the worst (C statistic, 0.56; 95% CI, 0.51-0.68). The ability for novel ONB staging systems to estimate disease progression across stages was also assessed. In the novel Kadish staging system, patients with stage VI disease were approximately 7 times as likely to experience disease progression as patients with stage I disease (hazard ratio [HR], 6.84; 95% CI, 1.60-29.20). Results were similar for the novel modified Kadish system (HR, 8.99; 95% CI, 1.62-49.85) and the novel Dulguerov system (HR, 6.86; 95% CI, 2.74-17.18).Conclusions and RelevanceThe study findings indicate that 5-year OS for ONB is favorable and that incorporation of Hyams grade into traditional ONB staging systems is associated with improved estimation of disease progression.

27 Background: Cholangiocarcinoma (CCA) is a devastating cancer with few effective treatment options. We have previously discovered LCK can activate AXL, a TAM receptor tyrosine kinase (RTK), by phosphorylation of AXL-Y866 ( J Hepatol 2022). AXL is known to confer therapeutic resistance to solid cancers. However, the role of AXL in CCA, and the impact of AXL-Y866 activation by LCK still remains to be elucidated. Here, we investigated the significance of AXL expression, signaling, and activation by LCK on Y866. Methods: We first evaluated the expression levels of AXL in CCA and its association with patient outcome using The Cancer Genome Atlas (TCGA) dataset. Next, to evaluate whether AXL inactivation sensitizes CCA cells to gemcitabine and cisplatin (GC), AXL downregulation was achieved via siRNA approach and the selective AXL inhibitor bemcentinib (Bem) using human CCA cell lines, HuCCT1 and RBE, and murine SB-1. We examined 50% inhibitory concentration (IC50) value on GC with or without AXL knockdown (KD) using cell viability assay. Then we assessed the efficacy of the combination of GC and Bem utilizing Calcusyn software and apoptosis by Annexin V assay. I n vivo efficacy was assessed using both a patient derived CCA xenograft and SB-1 a syngeneic model of CCA treated with vehicle, GC, Bem, or the combination. Next, we defined the interactome of wildtype AXL- Y866 compared to AXL-Y866F using biotin proximity labelling methods (BioID), validation of downstream target proteins using Western blot (WB), and a functional study with AXL-/- cells reconstituted with either AXL WT, or AXL Y866F. Results: In TCGA cohorts, AXL transcripts are more abundant than in normal adjacent liver, and higher levels are correlated with worse clinical outcome. In in vitro study, IC50 values of GC decreased after AXL KD. Synergistic effects were observed in the combination. The combination caused increased apoptosis compared to other treatments. In the in vivo studies, the combination suppressed tumor growth and the Ki67 levels, and the phosphorylation levels of PEAK1 decreased in the combination group compared to other groups. In BioID experiments, among the 222 proteins which were detected in both AXL WT and AXL Y866F interactomes, PEAK1 kinase, which localizes to actin cytoskeleton and focal adhesions, was most altered when Y866 was inactivated by the Y866F mutation. In gene ontology analysis, cell-cell adhesion and focal adhesion related proteins were enriched. In WB, we validated that the phosphorylation of PEAK1 decreased after AXL or LCK knockout (KO) and after Bem treatment in above in vivo study. In cell viability assay, reconstitution of AXL KO cells with WT AXL increased the IC50 to GC while reconstitution with AXL-Y866F did not. Conclusions: AXL inhibition sensitizes CCA cells to cytotoxic chemotherapy in preclinical model. LCK-AXL Y866-PEAK1 signaling axis is a potential target for the treatment of CCA.

AbstractBACKGROUNDDelirium, a common syndrome with heterogeneous etiologies and clinical presentations, is associated with poor long‐term outcomes. Recording and analyzing all delirium equally could be hindering the field's understanding of pathophysiology and identification of targeted treatments. Current delirium subtyping methods reflect clinically evident features but likely do not account for underlying biology.METHODSThe Delirium Subtyping Initiative (DSI) held three sessions with an international panel of 25 experts.RESULTSMeeting participants suggest further characterization of delirium features to complement the existing Diagnostic and Statistical Manual of Mental Disorders Fifth Edition Text Revision diagnostic criteria. These should span the range of delirium‐spectrum syndromes and be measured consistently across studies. Clinical features should be recorded in conjunction with biospecimen collection, where feasible, in a standardized way, to determine temporal associations of biology coincident with clinical fluctuations.DISCUSSIONThe DSI made recommendations spanning the breadth of delirium research including clinical features, study planning, data collection, and data analysis for characterization of candidate delirium subtypes.Highlights Delirium features must be clearly defined, standardized, and operationalized. Large datasets incorporating both clinical and biomarker variables should be analyzed together. Delirium screening should incorporate communication and reasoning.

Abstract The role of measurable residual disease (MRD) in multiple myeloma patients treated with chimeric antigen receptor (CAR) T cells is uncertain. We analyzed MRD kinetics during the first year after idecabtagene vicleucel (ide-cel) infusion in 125 relapsed/refractory multiple myeloma patients enrolled in KarMMa. At month 1 after ide-cel, there were no differences in progression-free survival (PFS) between patients in less than complete response (CR) versus those in CR; only MRD status was predictive of significantly different PFS at this landmark. In patients with undetectable MRD at 3 months and beyond, PFS was longer in those achieving CR versus <CR. Persistent MRD in the 10−6 logarithmic range and reappearance of normal plasma cells in MRD-negative patients were associated with inferior PFS. This study unveils different prognostic implications of serological and MRD response dynamics after ide-cel and suggests the potential value of studying the reappearance of normal plasma cells as a surrogate of loss of CAR T-cell functionality. Significance: This is one of the first studies evaluating the impact of CR and MRD dynamics after CAR T therapy in relapsed/refractory multiple myeloma. These data help interpret the prognostic significance of serological and MRD responses at early and late time points after CAR T-cell infusion.
