BACKGROUND: The National Cardiovascular Data Registry Left Atrial Appendage Occlusion Registry (LAAO) includes the vast majority of transcatheter LAAO procedures performed in the United States. The objective of this study was to develop a model predicting adverse events among patients undergoing LAAO with Watchman FLX. METHODS: Data from 41 001 LAAO procedures with Watchman FLX from July 2020 to September 2021 were used to develop and validate a model predicting in-hospital major adverse events. Randomly selected development (70%, n=28 530) and validation (30%, n=12 471) cohorts were analyzed with 1000 bootstrapped samples, using forward stepwise logistic regression to create the final model. A simplified bedside risk score was also developed using this model. RESULTS: Increased age, female sex, low preprocedure hemoglobin, no prior attempt at atrial fibrillation termination, and increased fall risk most strongly predicted in-hospital major adverse events and were included in the final model along with other clinically relevant variables. The median in-hospital risk-standardized adverse event rate was 1.50% (range, 1.03%–2.84%; interquartile range, 1.42%–1.64%). The model demonstrated moderate discrimination (development C-index, 0.67 [95% CI, 0.65–0.70] and validation C-index, 0.66 [95% CI, 0.62–0.70]) with good calibration. The simplified risk score was well calibrated with risk of in-hospital major adverse events ranging from 0.26% to 3.90% for a score of 0 to 8, respectively. CONCLUSIONS: A transcatheter LAAO risk model using National Cardiovascular Data Registry and LAAO Registry data can predict in-hospital major adverse events, demonstrated consistency across hospitals and can be used for quality improvement efforts. A simple bedside risk score was similarly predictive and may inform shared decision-making.

AbstractTixagevimab/cilgavimab (tix/cil) received emergency use authorization in December 2021 for pre‐exposure prophylaxis against COVID‐19 in moderately to severely immunocompromised patients. Our study aimed to describe the incidence of COVID‐19 infection and assess the immunologic risks associated with tix/cil in kidney, pancreas, liver, and heart transplant recipients. Retrospective chart review was completed to provide descriptive analysis. Outcomes data included COVID‐19 infection, severity of COVID‐19 infection, graft function, and rejection. Safety outcomes included cardiovascular (CV) and hypersensitivity events post tix/cil administration. A total of 410 transplant patients were included in the analysis: 20 heart, 92 liver, 243 kidney, 25 simultaneous pancreas/kidney, 23 simultaneous liver/kidney, and seven simultaneous heart/kidney. Twenty‐seven (6.5%) patients tested positive for COVID‐19 via PCR or antigen test post tix/cil. No apparent difference was observed in patients testing positive for COVID‐19 by type of organ transplant (p = .122). Twenty‐five of the 27 patients testing positive for COVID‐19 reported symptomatic infection, only nine of whom were hospitalized. No patients were mechanically ventilated and no deaths due to COVID‐19 occurred. No significant changes in graft function were observed. Clinically significant rejection was diagnosed and treated in four patients. COVID‐19 breakthrough infection rates remained low in immunocompromised solid organ transplant recipients who received tix/cil. No significant immunologic risks were observed.

AbstractAdolescents with chronic pain can at times present with disability out of proportion to diagnostic workup. This is also a defining feature of medical child abuse (MCA). The aim of this study was to identify themes from the clinical narratives of adolescents with chronic pain that may indicate concern for MCA. This qualitative, retrospective study at an academic children's hospital between 2011 and 2019 identified 37 adolescents aged 13–18 years old with chronic pain and varying levels of concern for MCA. Conventional, inductive content analysis was used to identify themes from the medical records of all patients, which were reviewed by an interdisciplinary panel of experts. Themes were organised into three tiers related to the level of concern for MCA: ‘Green zone’ themes including fatigue or sleep problems, psychosocial distress, and social withdrawal were common among all patients. ‘Yellow zone’ themes including fragmented care, caregiver catastrophising, caregiver misrepresentation, medical provider exasperation, and sick identity were more common among patients in whom medical providers raised concern for MCA. A single ‘red zone’ theme, reportable harm to the child, was only present in patients diagnosed by a child abuse paediatrician as having MCA. A visual display of the results is provided for further research and clinical application.

ImportanceManagement of sporadic vestibular schwannoma with radiosurgery is becoming increasingly common globally; however, limited data currently characterize patient outcomes in the setting of microsurgical salvage for radiosurgical failure.ObjectiveTo describe the clinical outcomes of salvage microsurgery following failed primary stereotactic radiosurgery (SRS) or fractionated stereotactic radiotherapy (FSRT) among patients with sporadic vestibular schwannoma.Design, Setting, and ParticipantsThis was a cohort study of adults (≥18 years old) with sporadic vestibular schwannoma who underwent salvage microsurgery following failed primary SRS/FSRT in 7 vestibular schwannoma treatment centers across the US and Norway. Data collection was performed between July 2022 and January 2023, with data analysis performed between January and July 2023.ExposureSalvage microsurgical tumor resection.Main Outcomes and MeasuresComposite outcome of undergoing less than gross total resection (GTR) or experiencing long-term facial paresis.ResultsAmong 126 patients, the median (IQR) age at time of salvage microsurgery was 62 (53-70) years, 69 (55%) were female, and 113 of 117 (97%) had tumors that extended into the cerebellopontine angle at time of salvage. Of 125 patients, 96 (76%) underwent primary gamma knife SRS, while 24 (19%) underwent linear accelerator-based SRS; the remaining patients underwent FSRT using other modalities. Postoperative cerebrospinal fluid leak was seen in 15 of 126 patients (12%), hydrocephalus in 8 (6%), symptomatic stroke in 7 (6%), and meningitis in 2 (2%). Each 1-mm increase in cerebellopontine angle tumor size was associated with a 13% increased likelihood of foregoing GTR (64 of 102 patients [63%]) or long-term postoperative House-Brackmann grade higher than I (48 of 102 patients [47%]) (odds ratio, 1.13; 95% CI, 1.04-1.23). Following salvage microsurgery, tumor growth–free survival rates at 1, 3, and 5 years were 97% (95% CI, 94%-100%), 93% (95% CI, 87%-99%), and 91% (95% CI, 84%-98%), respectively.ConclusionsIn this cohort study, more than half of patients who received salvage microsurgery following primary SRS/FSRT underwent less than GTR or experienced some degree of facial paresis long term. These data suggest that the cumulative risk of developing facial paresis following primary SRS/FSRT by the end of the patient’s journey with treatment approximates 2.5% to 7.5% when using published primary SRS/FSRT long-term tumor control rates.

ObjectiveThe aim was to evaluate representation of women in otolaryngology by examining authorship of research publications and presentations, awards, research grants, leadership, and membership in related organizations.MethodsAuthorship was reviewed from articles published in three otolaryngology journals from 2000 through 2021 to assess the frequency and percentages of female and combination of male and female gender authorship. Gender was evaluated for poster and scientific abstract presentations from 2007 to 2021. Gender representation was reviewed for institutional and society leadership positions, award, and grant recipients in the American Laryngological Society (ALA). Changes in the frequency of female and combination of male and female gender authorship over time were examined with Cochran‐Armitage test for trend.ResultsA total of 16,921 articles, 1,017 presentations, 480 leadership positions, 129 president positions, and 1,137 awards and grants were studied. Women were first authors in 4,153 (24.9%) and last authors in 2,935 (17.8%) published articles for which gender could be determined. Women were first authors in 372 (37.4%) presentations and last authors in 199 (20.2%). Most presentations had a combination of male and female presentation authorship (630, 68%). Women held 69 (14.4%) leadership positions. Of the award and grant recipients, 327 (28.8%) were female. Significant trends were observed for increasing female representation (first authorship publications increased 69.9% from 2000 to 2020, first authorship presentations increased 73.9% from 2007 to 2013, p < 0.001; leadership and awards from 3% to 18% representation, p = 0.02).ConclusionThe proportion of women receiving awards and holding leadership positions is increasing. Efforts that promote gender diversity may further increase representation of women in otolaryngology literature and among the grant and award winners.Level of EvidenceNA Laryngoscope, 134:2144–2152, 2024

INTRODUCTION: Studies suggest that the generation of durable T-cell immunity following coronavirus disease 2019 (COVID-19) vaccination protects against severe disease. The aim of this study was to measure cell-mediated immune response (CMIR) 1–2 months and 6 months after a third dose of a COVID-19 mRNA vaccine. METHODS: This prospective study (HumoRal and CellULar initial and Sustained immunogenicity in patients with inflammatory bowel disease [IBD]) evaluated CMIR at 28–65 days (t 1 ) after dose 2, 28–65 days (t 2 ) (n = 183) and 6 months (±45 days) (t 3 ) (n = 167) after a third dose of an mRNA COVID-19 vaccine. A small cohort had blood sample available 28–65 days (t 4 ) (n = 55) after a fourth dose. Primary outcomes were CMIR at (t 2 ) and (t 3 ). Secondary outcomes included the effect of immunosuppressing IBD medications on CMIR and response at (t 4 ). RESULTS: All patients had measurable CMIR at all time points. CMIR increased at t 2 compared with that at t 1 (median 1,467 responding cells per million (interquartile range [IQR] 410–5,971) vs 313 (94–960) P < 0.001). There was no significant waning in t 2 vs t 3 or significant boosting at t 4 . Those on anti–tumor necrosis factor monotherapy had a higher CMIR compared with those not on this therapy at t 2 (4,132 [IQR 1,136–8,795] vs 869 [IQR 343–3,221] P < 0.001) and t 3 (2,843 [IQR 596–6,459] vs 654 [IQR 143–2,067] P < 0.001). In univariable analysis, anti–tumor necrosis factor monotherapy was associated with a higher CMIR at t 2 ( P < 0.001) and t 3 ( P < 0.001) and confirmed in a multivariable model ( P < 0.001). DISCUSSION: A third dose of a COVID-19 vaccine boosts CMIR, and the response is sustained in patients with IBD.

AbstractVenetoclax (VEN) combined with hypomethylating agents (HMAs) is the standard of care for the treatment of patients with newly diagnosed acute myeloid leukemia (AML) unfit for intensive chemotherapy. To date, real‐world data published on HMAs plus VEN have been either single‐center studies or using community‐based electronic databases with limited details on mutational landscape, tolerability, and treatment patterns in elderly patients. Therefore, we conducted a multicenter retrospective study to assess the real‐world experience of 204 elderly patients (≥75 years) with newly diagnosed AML treated with HMAs plus VEN from eight academic centers in the United States. Overall, 64 patients achieved complete remission (CR; 38%) and 43 CR with incomplete count recovery (CRi; 26%) for a CR/CRi rate of 64%, with a median duration of response of 14.2 months (95% CI: 9.43, 22.1). Among responders, 63 patients relapsed (59%) with median overall survival (OS) after relapse of 3.4 months (95% CI, 2.4, 6.7). Median OS for the entire population was 9.5 months (95% CI, 7.85–13.5), with OS significantly worse among patients with TP53‐mutated AML (2.5 months) and improved in patients harboring NPM1, IDH1, and IDH2 mutations (13.5, 18.3, and 21.1 months, respectively). The 30‐day and 60‐day mortality rates were 9% and 19%, respectively. In conclusion, HMAs plus VEN yielded high response rates in elderly patients with newly diagnosed AML. The median OS was inferior to that reported in the VIALE‐A trial. Outcomes are dismal after failure of HMAs plus VEN, representing an area of urgent unmet clinical need.

BACKGROUND: Venous thromboembolism occurs in approximately 2% of patients undergoing abdominal and pelvic surgery for cancers of the colon, rectum, and anus and is considered preventable. The American Society of Colon and Rectal Surgeons recommends extended prophylaxis in high-risk patients, but there is low adherence to the guidelines. OBJECTIVE: This study aims to analyze the impact of venous thromboembolism risk-guided prophylaxis in patients undergoing elective abdominal and pelvic surgeries for colorectal and anal cancers from 2016 to 2021. DESIGN: This was a retrospective analysis. SETTING: The study was conducted at a multisite tertiary referral academic health care system. PATIENTS: Patients who underwent elective abdominal or pelvic surgery for colon, rectal, or anal cancer. MAIN OUTCOME MEASURES: Receipt of Caprini-guided venous thromboembolism prophylaxis, 90-day postoperative rate of deep vein thrombosis, pulmonary embolism, venous thromboembolism, and bleeding events. RESULTS: A total of 3504 patients underwent elective operations, of whom 2224 (63%) received appropriate thromboprophylaxis in the inpatient setting. In the postdischarged cohort of 2769 patients, only 2% received appropriate thromboprophylaxis and no thromboembolic events were observed. In the group receiving inappropriate thromboprophylaxis, at 90 days postdischarge, the deep vein thrombosis, pulmonary embolism, and venous thromboembolism rates were 0.60%, 0.40%, and 0.88%, respectively. Postoperative bleeding was not different between the 2 groups. LIMITATIONS: Limitations to our study include its retrospective nature, use of aggregated electronic medical records, and single health care system experience. CONCLUSION: Most patients in our health care system undergoing abdominal or pelvic surgery for cancers of the colon, rectum, and anus were discharged without appropriate Caprini-guided venous thromboembolism prophylaxis. Risk-guided prophylaxis was associated with decreased rates of inhospital and postdischarge venous thromboembolism without increased bleeding complications. See Video Abstract. MARGEN DE MEJORA: EL IMPACTO DE LA TROMBOPROFILAXIS RECOMENDADA POR LAS DIRECTRICES EN PACIENTES SOMETIDOS A CIRUGÍA ABDOMINAL POR CÁNCER COLORRECTAL Y ANAL EN UN CENTRO DE REFERENCIA TERCIARIO ANTECEDENTES: El tromboembolismo venoso ocurre en aproximadamente el 2% de los pacientes sometidos a cirugía abdominal y pélvica por cánceres de colon, recto y ano, y se considera prevenible. La Sociedad Estadounidense de Cirujanos de Colon y Recto recomienda una profilaxis prolongada en pacientes de alto riesgo, pero el cumplimiento de las directrices es bajo. OBJETIVO: Este estudio tiene como objetivo analizar el impacto de la profilaxis guiada por el riesgo de tromboembolismo venoso (TEV) en pacientes sometidos a cirugías abdominales y pélvicas electivas por cáncer colorrectal y anal entre 2016 y 2021. DISEÑO: Este fue un análisis retrospectivo. AJUSTE: El estudio se llevó a cabo en un sistema de salud académico de referencia terciaria de múltiples sitios. PACIENTES: Pacientes sometidos a cirugía abdominal o pélvica electiva por cáncer de colon, recto o ano. PRINCIPALES MEDIDAS DE RESULTADO: Recepción de profilaxis de tromboembolismo venoso guiada por Caprini, tasa postoperatoria de 90 días de trombosis venosa profunda, embolia pulmonar, tromboembolismo venoso y eventos de sangrado. RESULTADOS: Un total de 3.504 pacientes se sometieron a operaciones electivas, de los cuales 2.224 (63%) recibieron tromboprofilaxis adecuada en el ámbito hospitalario. En el cohorte de 2.769 pacientes después del alta, solo el 2% recibió tromboprofilaxis adecuada en la que no se observaron eventos tromboembólicos. En el grupo que recibió tromboprofilaxis inadecuada, a los 90 días después del alta, las tasas de trombosis venosa profunda, embolia pulmonar y tromboembolia venosa fueron del 0,60%, 0,40% y 0,88%, respectivamente. El sangrado posoperatorio no fue diferente entre los dos grupos. LIMITACIONES: Las limitaciones de nuestro estudio incluyen su naturaleza retrospectiva, el uso de registros médicos electrónicos agregados y la experiencia de un solo sistema de atención médica. CONCLUSIÓN: La mayoría de los pacientes en nuestro sistema de salud sometidos a cirugía abdominal o pélvica por cánceres de colon, recto y ano fueron dados de alta sin una profilaxis adecuada de TEV guiada por Caprini. La profilaxis guiada por el riesgo se asoció con menores tasas de tromboembolismo venoso hospitalario y dado de alta sin un aumento de las complicaciones de sangrado.
