Background As the COVID-19 pandemic moves into the survivorship phase, questions regarding long-term lung damage remain unanswered. Previous histopathological studies are limited to autopsy reports. We studied lung specimens from COVID-19 survivors who underwent elective lung resections to determine whether post-acute histopathological changes are present. Methods In this multicenter observational study, we included adult COVID-19 survivors (n=11) who had recovered but subsequently underwent unrelated elective lung resection for indeterminate lung nodules or lung cancer. We compared these to an age- and procedure-matched control group who never contracted COVID-19 (n=5), and an end-stage COVID-19 group (n=3). A blinded pulmonary pathologist examined the lung parenchyma focusing on four compartments: airways, alveoli, interstitium, and vasculature. Results Eleven COVID-19 survivors with asymptomatic (n=4), moderate (n=4), and severe (n=3) COVID-19 infections underwent elective lung resection at a median 68.5 days (range 24-142) after COVID-19 diagnosis. The most common operation was lobectomy (75%). On histopathological examination, no differences were identified between the lung parenchyma of COVID-19 survivors and controls across all compartments examined. Conversely, patients in the end-stage COVID-19 group showed fibrotic diffuse alveolar damage with intra-alveolar macrophages, organizing pneumonia, and focal interstitial emphysema. Conclusions In this first study to examine the lung parenchyma of COVID-19 survivors, we did not find distinct post-acute histopathological changes to suggest permanent pulmonary damage. These results are reassuring for COVID-19 survivors who recover and become asymptomatic.

Objective To compare outcomes of juvenile nasopharyngeal angiofibroma (JNA) resection between embolized and non‐embolized cohorts, and between transarterial embolization (TAE) and direct puncture embolization (DPE). Data Sources Per PRISMA guidelines, PubMed, Embase, Web of Science, Scopus, and Cochrane databases were searched for publications prior to or in 2021. Materials and Methods Original English manuscripts investigating the resection of JNA with and without preoperative embolization were included. Embolization type, recurrence rate, complication rates, blood loss, and transfusions were extracted. Risk of bias was assessed by the Risk of Bias in Non‐randomized Studies—of Interventions method. Results There were 61 studies with 917 patients included. Preoperative embolization was performed in 79.3% of patients. Of those embolized, 75.8% (N = 551) underwent TAE and 15.8% (N = 115) underwent DPE. JNA recurrence in embolized patients was lower than in non‐embolized patients (9.3% vs. 14.4%; odds ratio [OR]: 0.61, 95% confidence interval [CI]: 0.35, 1.06). DPE resulted in lower rates of disease recurrence (0% vs. 9.5%; OR: 0.066, 95% CI: 0.016, 0.272) and complications (1.8% vs. 21.9%; OR: 0.07, 95% CI: 0.02, 0.3) than TAE. A random effects Bayesian model was performed to analyze the difference in mean blood loss in 6 studies that included both embolized and non‐embolized patients. This analysis showed a mean reduction in blood loss of 798 mL in the embolized group. Conclusions We found embolization decreases blood loss in JNA resection. DPE led to improved recurrence and complication rates when compared to TAE, but future prospective studies are needed to further evaluate which embolization technique can optimize outcomes in JNA.

Background: Ex vivo lung perfusion (EVLP) is used to assess and preserve lungs prior to transplantation. However, its inherent immunomodulatory effects are not completely understood. We examine perfusate and tissue compartments to determine the change in immune cell composition in human lungs maintained on EVLP. Methods: Six human lungs unsuitable for transplantation underwent EVLP. Tissue and perfusate samples were obtained during cold storage and at 1-, 3-and 6-h during perfusion. Flow cytometry, immunohistochemistry, and bead-based immunoassays were used to measure leukocyte composition and cytokines. Mean values between baseline and time points were compared by Student's t test. Results: During the 1st hour of perfusion, perfusate neutrophils increased (+22.2 ± 13.5%, p < 0.05), monocytes decreased (−77.5 ± 8.6%, p < 0.01) and NK cells decreased (−61.5 ± 22.6%, p < 0.01) compared to cold storage. In contrast, tissue neutrophils decreased (−22.1 ± 12.2%, p < 0.05) with no change in monocytes and NK cells. By 6 h, perfusate neutrophils, NK cells, and tissue neutrophils were similar to baseline. Perfusate monocytes remained decreased, while tissue monocytes remained unchanged. There was no significant change in B cells or T cell subsets. Pro-inflammatory cytokines (IL-1b, G-CSF, IFN-gamma, CXCL2, CXCL1 granzyme A, and granzyme B) and lymphocyte activating cytokines (IL-2, IL-4, IL-6, IL-8) increased during perfusion. Conclusions: Early mobilization of innate immune cells occurs in both perfusate and tissue compartments during EVLP, with neutrophils and NK cells returning to baseline and monocytes remaining depleted after 6 h. The immunomodulatory effect of EVLP may provide a therapeutic window to decrease the immunogenicity of lungs prior to transplantation.

ObjectivesTo quantify the current proportion of women in otolaryngology at different levels of professorship and determine whether these proportions differ by US region.MethodsAcademic rank and gender at all ACGME‐accredited otolaryngology programs in the United States were determined from departmental websites, Doximity, and LinkedIn from November 2021 to March 2022. Individuals were then further organized using US Census Bureau‐designated regions.ResultsAmong the 2682 faculty positions at 124 ACGME‐accredited programs, women held 706 (26.3%) of these positions. Female representation was highest at the assistant professorship level, with women holding 286 (37.2%) positions out of a total 769. At the associate professorship level, women held 141 (27.6%) of the 511 total positions. The largest gender disparity is seen at the full professorship level; only 69 (13.6%) positions out of 508 were held by women. Out of every region and rank, only assistant professorship in the West had no significant difference in percentages of men and women (p = .710). Female representation of professors in the Northeast was significantly lower than that of our reference group (the South; β = −10.9, p = .020).ConclusionsOtolaryngology has exhibited great progress in increasing female representation, with assistant professorship in the West reaching gender parity. However, the gender gap at other faculty levels still leaves much to be desired, particularly in senior ranks. The lack of otolaryngologists at senior ranks is detrimental to mentorship of junior faculty, residents, and medical students. Renewed efforts should be made to decrease the gender disparity in the South, Northeast, and particularly at the professorship level.

Objectives Insurance coverage plays a critical role in head and neck cancer care. This retrospective study examines how insurance coverage affects nasopharyngeal carcinoma (NPC) survival in the United States using the Surveillance, Epidemiology, and End Results (SEER) program database. Design, Setting, and Participants A total of 2,278 patients aged 20 to 64 years according to the International Classification of Diseases for Oncology (ICD-O) codes C11.0–C11.9 and ICD-O histology codes 8070–8078 and 8080–8083 between 2007 and 2016 were included and grouped into privately insured, Medicaid, and uninsured groups. Log-rank test and multivariable Cox's proportional hazard model were performed. Main Outcome Measures Tumor stage, age, sex, race, marital status, disease stage, year of diagnosis, median household county income, and disease-specific survival outcomes including cause of death were analyzed. Results Across all tumor stages, privately insured patients had a 59.0% lower mortality risk than uninsured patients (hazard ratio [HR]: 0.410, 95% confidence interval [CI]: [0.320, 0.526], p < 0.01). Medicaid patients were also estimated to have 19.0% lower mortality than uninsured patients (HR: 0.810, 95% CI: [0.626, 1.048], p = 0.108). Privately insured patients with regional and distant NPC had significantly better survival outcomes compared with uninsured individuals. Localized tumors did not show any association between survival and type of insurance coverage. Conclusion Privately insured individuals had significantly better survival outcomes than uninsured or Medicaid patients, a trend that was preserved after accounting for tumor grade, demographic and clinicopathologic factors. These results underscore the difference in survival outcomes when comparing privately insured to Medicaid/uninsured populations and warrant further investigation in efforts for health care reform.
