Objective: To evaluate the impact of cochlear implantation (CI) and simultaneous endolymphatic sac decompression (ELSD) on vestibular and audiometric outcomes in patients with advanced Ménière disease (MD). Study design: Historical cohort. Setting: Tertiary academic medical center. Patients: Patients with medically refractory MD who underwent CI with or without simultaneous ELSD from 2000 through 2024. Interventions: CI with or without ELSD. Main outcome measures: Post-CI patient-reported changes in vertigo severity and frequency, Consonant-Nucleus-Consonant word (CNCw) scores, and AzBio sentences in quiet scores. Results: Ninety-nine patients with preoperative vertigo secondary to MD were eligible for study, including 17 (17%) who underwent simultaneous ELSD. In total, 15 (88%) and 2 (12%) of the 17 patients with simultaneous ELSD reported improvement and stability in vertigo severity, respectively; in comparison, 26 (32%), 40 (49%), and 16 (20%) of the 82 patients with CI alone reported improvement, stability, and worsening in vertigo severity, respectively ( P <0.001). Likewise, 15 (88%) and 2 (12%) of the patients with simultaneous ELSD reported improvement and stability in vertigo frequency, respectively, whereas 21 (26%), 43 (52%), and 18 (22%) of patients with CI alone reported improvement, stability, and worsening in vertigo frequency, respectively ( P <0.001). Post-CI speech recognition scores were not significantly different between the simultaneous ELSD and CI alone groups [median (IQR) CNCw 70 (38 to 82) vs. 72 (58 to 82) and median (IQR) AzBio quiet 87 (67 to 96) vs. 87 (73 to 94), respectively]. Conclusions: In patients with MD, CI with simultaneous ELSD provides improvement in vertigo symptoms and similar audiometric outcomes when compared with CI alone. In appropriately selected patients with both refractory vestibular symptoms and sensorineural hearing loss meeting criteria for implantation, CI with simultaneous ELSD offers improvement in severity and frequency of vertigo as well as successful auditory rehabilitation.

Abstract The cortical asymmetry index evaluates the cortical thickness asymmetry between hemispheres. We investigated cortical asymmetry index in asymptomatic and symptomatic mutation carriers of autosomal dominant Alzheimer’s disease to explore the brain asymmetry within the Alzheimer’s disease continuum. Sixty baseline T1-weighted MRI scans were obtained from the Clinic Barcelona cohort. Baseline and longitudinal MRI data from 564 participants within the dominantly inherited Alzheimer network observational study were used as an independent, confirmatory cohort. Cerebrospinal fluid and plasma neurofilament light chain levels were included when available. Cortical thickness was calculated using Freesurfer and cortical asymmetry index was calculated via an open-source pipeline. Cross-sectional analyses examined cortical asymmetry index differences based on clinical classification and APOE ε4 status, adjusting for age, sex and estimated years from onset, while correlations were assessed with age, estimated years from onset, mini-mental state examination scores, and neurofilament light. Longitudinal cortical asymmetry index evolution was modelled using generalized additive models in the dominantly inherited Alzheimer network observational study cohort, incorporating age, sex, and the interaction between group and estimated years from onset. The cortical asymmetry index successfully distinguished asymptomatic mutation carrier and symptomatic mutation carriers from healthy controls in the Clinic Barcelona cohort and symptomatic mutation carriers from controls in dominantly inherited Alzheimer network observational study. Higher cortical asymmetry index in mutation carriers (asymptomatic mutation carrier and symptomatic mutation carriers combined) and in symptomatic mutation carriers were associated with higher plasma neurofilament light levels, a closer proximity to symptom onset, and lower mini-mental state examination in the Clinic Barcelona cohort. In the dominantly inherited Alzheimer network observational study cohort, mutation carriers exhibited increased cortical asymmetry index compared to controls and correlated with elevated neurofilament light (plasma and Cerebrospinal fluid), lower mini-mental state examination, and a closer proximity to symptom onset. APOE3/3 carriers showed greater asymmetry than other APOE genotypes and significant cortical asymmetry index differences between asymptomatic mutation carrier and symptomatic mutation carriers. Longitudinally, cortical asymmetry index increased over time significantly in symptomatic mutation carriers. These findings underscore brain asymmetry as a potential biomarker for early Alzheimer’s disease progression in autosomal dominant Alzheimer’s disease, with implications for detection and monitoring tracking disease-related neuroanatomical changes.

Physician burnout is prevalent and contributes to the high number of physicians choosing to leave clinical practice. The field of hematology-oncology (HO) poses unique challenges for trainees and staff physicians who have to deliver bad news, manage complicated psychosocial situations, deal with the limited ability to prolong life, and juggle multiple time-sensitive demands from coworkers, patients, and families. Furthermore, they often face the death of their patients, along with its emotional toll on patients’ families and the physicians themselves. Burnout in HO is prevalent and increasing, with many physicians reporting in several studies that they plan to reduce working hours and/or retire early. The demand for hematologists and oncologists is rapidly rising, but in the setting of a worsening HO workforce shortage and an increasing number of patients with cancer. Therefore, it is imperative to develop strategies to mitigate or address burnout in HO physicians to improve well-being and prevent attrition. Herein, we describe risk factors and causes of physician burnout in HO trainees and practicing physicians in the United States, with a focus on institutional and individual strategies to address this issue. We also provide recommendations to address the burnout epidemic from the HO standpoint.

An ST-segment elevation myocardial infarction is a life-threatening condition within the spectrum of acute coronary syndrome, with well-recognized implications for short-term and long-term health outcomes. Retrospective review of our institutional electronic health records identified patterns of inaccurate acute coronary syndrome diagnostic assignment, including the presence of erroneous ST-segment elevation myocardial infarction diagnoses in discharge records. Such erroneous diagnoses in the durable health record may increase risk to patients through inadequate risk assessment and inappropriate follow-up care. Misapplication of a shortcut in our electronic health record system for rapidly ordering emergent cases was identified as a potential cause of the quality gap. To address this issue, a nurse-led quality improvement project was developed by using the define, measure, analyze, improve, and control framework. The project intervention decreased the percentage of patients with erroneous diagnoses from 24% to 7% and marginally improved nursing staff satisfaction. Our project successfully addressed an institutional quality concern. Our goal of reducing erroneous discharge diagnoses with minimal disruption to our existing practice was achieved, positively affecting our patients. Including both nurse leaders and frontline health care workers ensured the success of our project.

BACKGROUND AND OBJECTIVES: Stereotactic radiosurgery (SRS) for brain arteriovenous malformations (AVMs) can cause radiation-induced changes (RIC), but its interactions with AVM embolization are not well established. The aim of this study was to assess the effect of previous embolization on RIC in SRS-treated AVM patients. METHODS: Data of AVM patients treated with single-session SRS from 1987 to 2018 were retrieved from the International Radiosurgery Research Foundation. Univariable and stepwise backward logistic regression models were used to identify RIC predictors. Patients were stratified into those who received pre-SRS embolization (E + SRS) vs those who did not (SRS-only). Radiologic RIC (rRIC) was the primary end point. Secondary outcomes included symptomatic RIC (sRIC) and permanent symptomatic RIC (pRIC). RESULTS: Among 1187 AVM patients, the mean age was 36.4 years (SD 16.8), with 50.4% female patients. AVMs had a mean untreated AVM volume of 5.2 cm 3 . A total of 130 patients (11%) underwent neoadjuvant embolization (E + SRS). The overall rRIC and sRIC rates were 32.8% and 12.1%, respectively, with time to rRIC and sRIC being significantly longer in the E + SRS vs SRS-only cohorts (103.6 ± 339.4 vs 11.3 ± 12.5 and 60.4 ± 262.9 vs 9.5 ± 9.0 months, respectively). Seizures at presentation and ≥3-cm untreated AVM volume significantly correlated with a higher likelihood of rRIC (adjusted odds ratio [aOR] 2.32 [1.25-4.30] and aOR 2.77 [1.24-6.16], respectively). Age and pre-SRS embolization were associated with a significantly lower risk of rRIC (aOR 0.97 [0.96-0.99] and aOR 0.32 [0.13-0.74], respectively). The E + SRS cohort had significantly reduced odds of rRIC (aOR = 0.37 [0.15-0.89]) and pRIC (aOR = 0.04 [0.00-0.30]) after adjusting for significant covariates. CONCLUSION: Seizures at presentation and larger untreated AVM volume were independently associated with an increased risk of rRIC, whereas older age and pre-SRS embolization were protective. Notably, patients who underwent embolization before SRS had lower odds of rRIC and pRIC, with delayed onset of complications compared with SRS-only.

PURPOSE To compare patient-reported and clinical outcomes between radical cystectomy (RC) and bladder-sparing therapy (BST) in patients with recurrent high-grade non–muscle-invasive bladder cancer (NMIBC). PATIENTS AND METHODS This pragmatic, prospective observational cohort study was designed with patients, who selected and prioritized outcomes. Eligible adults were candidates for both RC or BST, had previous induction Bacillus Calmette-Guérin (BCG), and received their last treatment within 12 months. The primary outcome was the EORTC-QLQ-C30 physical function scale at 12 months. Secondary outcomes included other EORTC-QLQ-C30 scales, depression, anxiety, bladder cancer–specific quality of life (QOL), financial burden, and cancer-specific outcomes. Targeted maximum likelihood estimation (TMLE) was used to calculate average treatment effect (ATE) estimates between arms. Inverse probability weighted risk ratios (wRR) were calculated using quasi-Poisson regression. RESULTS Of 570 participants (mean age 71.4 years; 21% female), 371 selected BST and 199 selected RC. Physical function was significantly worse in the RC arm at 3 months; by 9 months, there was no difference between arms, and at 12 months, physical function did not differ (ATE, 0.9; 95% CI, –0.6 to 2.4; P = .22). RC was associated with better emotional function, generic health-related QOL, and financial burden, and lower depression and anxiety, while BST was associated with better bowel and sexual health. Cancer-specific survival was 99% for BST versus 96% for RC (wRR, 0.99; 95% CI, 0.97 to 1.01). RC was associated with a higher risk of adverse events and serious adverse events, including a 90-day mortality rate of 2.5%. CONCLUSION Most patient-prioritized outcomes were similar or better among participants who chose RC compared with BST. These findings support the continued role of RC in managing recurrent high-grade NMIBC.

PURPOSE Low-grade serous carcinoma (LGSOC) of the ovary, fallopian tube, or peritoneum is a hormonally driven, relatively chemoresistant malignancy with limited treatment options in the recurrent setting. Given frequent estrogen receptor (ER) expression and dysregulation of the cyclin-dependent kinases 4 and 6 (CDK4/6)–p16–Rb pathway, features shared with hormone receptor–positive breast cancer, dual endocrine, and CDK4/6 inhibition is a biologically rational strategy. This phase II trial evaluated ribociclib plus letrozole in recurrent LGSOC. METHODS This open-label, single-arm, multicenter phase II study enrolled women with measurable, recurrent LGSOC. Patients received ribociclib (600 mg orally, once daily, days 1-21 of a 28-day cycle) and letrozole (2.5 mg orally, once daily). The primary end point was investigator-assessed objective response rate (ORR) per RECIST 1.1. Secondary end points included clinical benefit rate (CBR), progression-free survival (PFS), overall survival (OS), and safety. RESULTS Of 74 patients screened, 51 were enrolled and 49 treated. The confirmed ORR was 30.6% (90% CI, 19.9 to 43.2), including one complete and 14 partial responses. Among responders, the median duration of response was 21.2 months. The CBR was 84% (90% CI, 72.5 to 91.6). The median PFS was 14.5 months (90% CI, 10.1 to 28.8), and the median OS was 44.5 months (90% CI, 31.8 to not reached). The most common grade ≥3 adverse event (AE) was neutropenia (47%), managed with dose modifications. Three grade 5 events (6%) occurred but were unrelated to treatment. Treatment discontinuation because of AEs occurred in 4%. No dose-limiting toxicities were observed. CONCLUSION Ribociclib plus letrozole met the primary end point, achieving meaningful response rates and durable disease control in recurrent LGSOC. The safety profile was consistent with prior CDK4/6 inhibitor studies. This combination represents a therapeutic option in this rare and genomically distinct subtype.

Abstract Background 0.05% Chlorhexidine gluconate (CHG) is now commonly used as an antiseptic irrigation for inflatable penile prosthesis (IPP) surgery. Limited in vitro data suggest compatibility of 0.05% CHG with antibiotic impregnated IPP devices; however, very little clinical research exists to guide use of 0.05% CHG in this population. Aim Assess the relationship of 0.05% CHG and antibiotic impregnated IPP infection in a large multi-institutional cohort. Methods We retrospectively reviewed a multi-institutional cohort of patients who underwent antibiotic impregnated IPP implantation. We identified cases using intraoperative 0.05% CHG and an equal number of consecutive control cases without 0.05% CHG use from each center for comparison. The primary outcome was IPP infection requiring explantation. Patient demographics and surgical variables were analyzed using chi-square tests and multivariable logistic regression to identify variables associated with infection. Outcomes The primary outcome was IPP infection requiring device explanation. Results Among 14 participating institutions, 761 cases using an antibiotic impregnated IPP were analyzed. Of these, 348 (45.7%) had 0.05% CHG used during the case. Median follow-up was 4 months (interquartile range 1-12) for the 0.05% CHG group and 8 months (interquartile range 2-21) for the control group. Intraoperative 0.05% CHG utilization was not associated with antibiotic impregnated IPP infection rate (1.9% vs. 2.0%, P = .9). On multivariable analysis, prior IPP infection (OR 6.32, 95% CI 1.32-30.2, P = .021) and prior priapism (OR 10.01, 95% CI 1.18-89.7, P = .039) were associated with increased infection risk. Clinical implications The use of 0.05% CHG irrigation with antibiotic impregnated IPPs was associated with similar infection rates compared to antibiotic irrigation. Strengths and limitations Limitations include the use of a historical comparator cohort which may introduce unknown confounders, practice variation between multiple sites, shorter follow-up in the 0.05% CHG cohort, and the low incidence of IPP infection which may limit statistical power despite a large sample. The major strengths include the large, multi-institutional cohort, and the use of consecutive patients to minimize selection bias. Conclusion 0.05% CHG utilization was not associated with infection rates in antibiotic impregnated IPPs.

Abstract The benefit of rituximab maintenance after first-line (1L) bendamustine-rituximab (BR) in patients with mantle cell lymphoma (MCL) remains uncertain, with inconsistent results from the phase 2 MAINTAIN trial and several retrospective studies. We conducted a large retrospective study at 27 US and Canadian academic centers to examine the benefit of rituximab maintenance after BR. A total of 911 patients received 1L BR between 2010 and 2020, and 703 had an objective response and no evidence of disease progression at the 3-month post-BR landmark. Among those, 394 (56%) received rituximab maintenance and 309 (44%) did not, with largely similar baseline patient and disease characteristics. In the landmark analysis, rituximab maintenance was associated with improved event-free survival (EFS; median, 49.9 vs 29.7 months; P&lt; .001) as well as overall survival (OS; median, 109.5 vs 74.2 months; P&lt; .001). The EFS and OS benefits were observed across most of the subgroups. EFS and OS differences were statistically significant in those who achieved a complete response to 1L BR (n = 590; median EFS, 62.7 vs 31.1 months [P&lt; .001]; median OS, 136.1 vs 75.3 months [P&lt; .001]), but the analysis among those who achieved a partial response to 1L BR was limited by the small sample size. These results provide additional evidence for the survival benefit of rituximab maintenance after BR in MCL and support its use in clinical trial design and routine practice.

Objectives: In the United States, training for physicians who manage critically ill adult patients (intensivists) evolved through parallel subspecialty critical care medicine (CCM) pathways with significant commonality. The Society of Critical Care Medicine Adult Critical Care Physician Core Knowledge and Skills Task Force aimed to delineate the common core knowledge and skills required of all intensivists. Design: A master list of content areas and procedural skills was compiled from all CCM subspecialty program requirements and blueprints of the certification examinations. Using a modified Delphi approach, participants were asked to categorize the knowledge items as “advanced knowledge is essential,” “general, but not advanced, knowledge is essential,” or “knowledge is not essential.” Procedures were categorized as “intensivist performs routinely,” “intensivist only performs in an emergency,” or “intensivist knows” about the procedure. Setting: Representatives from CCM stakeholder organizations, including accreditation and certification organizations, critical care societies, and program directors’ societies, were invited to participate. SUBJECTS: Members of the Adult Critical Care Physician Core Knowledge and Skills Task Force of the Society of Critical Care Medicine. Interventions: For the first two rounds of the modified Delphi process, Research Electronic Data Capture was used. For the third and fourth rounds, the process was completed through online meetings with Zoom (Zoom Video Corporations, San Jose, CA) utilizing Zoom’s polling feature. Measurements and Main Results: A total of 541 items were determined to be essential, with 145 requiring advanced knowledge and 323 requiring general knowledge. For 73 items, consensus regarding advanced vs. general could not be achieved, but they remained essential. Only eight items were felt to be nonessential. Of the 16 procedures, most were categorized as “intensivist performs.” Conclusions: The large number of items included in the list of essential knowledge and skills demonstrates the complexity of modern CCM. Utilization of a common framework across the subspecialties of CCM could lead to greater harmonization among the fellowship program requirements and certification examinations.
