Effect of tobacco use on Zenker's diverticulotomy outcomes.

OBJECTIVE: To compare clinical outcomes in patients with and without history of tobacco use who underwent Zenker's diverticulotomy (ZD). STUDY DESIGN: Single institution retrospective review. SETTING: Tertiary care academic hospital. METHODS: A retrospective review of patients who underwent ZD via an open stapler, rigid endoscopic CO2 laser, stapler or harmonic scalpel, and flexible endoscopic technique from January 2006 to December 2020 was performed. Data were abstracted for patient demographics, diverticular features, and rates of adverse events and symptomatic recurrence. RESULTS: Out of 424 patients, 146 (34.4 %) had a history of tobacco use: 126 (29.7 %) were former smokers, and 20 (4.7 %) were active smokers. In univariable cross-sectional analyses, the likelihood of postoperative bleeding, perforation, emergency department visits, unplanned readmission, or recurrence did not demonstrate an association with tobacco use history even after adjustment for age, sex, and surgical approach. Similarly, in Cox Proportional Hazards regression, tobacco use was not associated with an increased risk of recurrence, even after correcting for age, sex, and type of surgery. The median time to recurrence observed in our cohort was 11.5 years amongst non-smokers, 8.7 years amongst former smokers, and 1.2 years amongst active smokers (p = 0.94). CONCLUSIONS: There were no significant differences in post-operative adverse events or frequency of recurrence of ZD between active, former, and non-smokers. Although underpowered and not statistically significant, median time to recurrence appears to be shorter in smokers when compared with former and non-smokers following surgery.

Safety outcomes and patient convenience in outpatient parotidectomy.

BACKGROUND: Parotidectomies have historically been performed on an inpatient basis despite being well-tolerated surgeries with minimal postoperative wound care and low rates of complications at high-volume institutions. Past studies have supported the safety of outpatient surgery for parotidectomy but have been limited to superficial parotidectomy and have not addressed the patient experience surrounding the surgical intervention such as pre-operative and post-operative care and communication. PURPOSE: This study assesses the impact of outpatient superficial, deep, and partial parotid surgery on various parameters including surgical safety, distance traveled for care, utilization of telehealth, and patient-initiated communication. MATERIALS AND METHODS: Retrospective study from January 2020 to October 2021. Patients undergoing superficial lobe, deep lobe, and partial parotidectomies for benign and malignant pathologies were divided into inpatient and outpatient cohorts. A multivariable model examined the relationship between admission status and surgical complications, adjusted for age, sex, and tumor size. RESULTS: 159 patients total, 94 outpatient and 65 inpatients. No statistical difference in rates of surgical complications with the exception of salivary leak. There was an increased rate of salivary leak reported in the inpatient group (OR 5.4, 95 % CI 1.6 to 18.0, p = 0.01). Mean patient travel distance of 354 miles one-way. Post-operatively, 76 % were evaluated via video visit. Following discharge, >55 % of patients initiated communication with the surgical team, which was not statistically different between the groups. CONCLUSIONS: Outpatient parotidectomy is safe and can be more convenient, but telehealth communication must be balanced with rigorous attention to patient education.

Flexible endoscopic Zenker's diverticulotomy - A retrospective review of outcomes in 75 patients.

OBJECTIVE: Flexible endoscopic Zenker's diverticulotomy (FEZD) is a procedure performed primarily by gastroenterologists for treatment of symptomatic Zenker's diverticulum (ZD). Given the lack of prior investigations with large sample sizes, we report on one of the largest series of patients who underwent FEZD. METHODS: A review of patients who underwent FEZD at our institution from 2006 to 2021 was performed. Data were abstracted for patient demographics, clinical features, procedural characteristics, adverse events, and outcomes. RESULTS: A total of 75 patients (37 women) with mean age of 77.9 (33-102) years and mean (range) follow-up of 1.1 (0-13.2) years were identified. 67.9 % of FEZD cases were performed under general anesthesia. The mean procedure time was 37.1 min. Same day discharge and resumption of oral intake was seen in 56.4 % and 57.1 % of cases, respectively. Adverse events included intraprocedural bleeding (15.7 %) controlled with endoscopic means, infection (4.8 %) exclusively managed with antibiotics in all but one case, subcutaneous emphysema (2.4 %), and perforation (10.7 %) conservatively managed in all but one case. 97.6 % of patients had sustained subjective improvement in symptoms following their procedure. Fifteen patients (20 %) experienced recurrence after undergoing initial FEZD-26.7 % percent of whom were sufficiently treated with repeat FEZDs. Younger age was associated with recurrence (p < 0.01). CONCLUSION: FEZD is an effective, safe procedure for the management of symptomatic ZD. It is a viable alternative for patients in whom otorhinolaryngological procedures via rigid endoscopy are not an option.

Risk of hydroxychloroquine retinopathy in the community.

OBJECTIVES: We aimed to estimate the risk of HCQ retinopathy and its risk factors among incident users in the community. METHODS: Using the Rochester Epidemiology Project, a record-linkage system, a cohort of incident users of HCQ was identified from 27 counties in the American upper Midwest. HCQ retinopathy was defined based on characteristic paracentral automated 10-2 visual field (10-2 AVF) defects and parafoveal retinal photoreceptor layer changes on spectral domain optical coherence tomography. Cumulative incidence rates were estimated adjusting for competing risk of death. Risk factors for HCQ retinopathy were examined using Cox models. RESULTS: The study included 634 incident HCQ users (mean age at initial HCQ use was 53.7 years, 79% females, 91% white). Most common indications for HCQ were RA (57%) and SLE (19%). The average follow-up length was 7.6 years. Eleven patients developed HCQ retinopathy (91% females, 91% white). The majority used HCQ for RA (91%). The cumulative incidence rate at year 5 was 0%, which increased to 3.9% (95% CI 2.0, 7.4) by 10 years. Taking an HCQ dose ≥5 mg/kg was associated with a hazard ratio (HR) of 3.59 (95% CI 1.09, 11.84) compared with lower doses. There was a 48% increase [HR 1.48 (95% CI 1.03, 2.14)] in the risk of HCQ retinopathy for each 100 g of HCQ cumulative dose. CONCLUSION: The risk of HCQ retinopathy at 10 years of use is lower compared with previous prevalence-based estimations. A dose ≥5 mg/kg was associated with higher HCQ retinopathy risk.

Association of Rurality and Neighborhood Level Socioeconomic Deprivation with Perioperative Health Status in Total Joint Arthroplasty Patients: Analysis from a Large, Tertiary Care Hospital.

BACKGROUND: Individual socioeconomic status (SES) is associated with disparities in access to care and worse outcomes in total joint arthroplasty (TJA). Neighborhood-level SES measures are sometimes used as a proxy for individual-level SES, but the validity of this approach is unknown. We examined neighborhood level SES and rurality on perioperative health status in TJA. METHODS: The study population comprised 46,828 TJA surgeries performed at a tertiary care hospital. Community area deprivation index (ADI) was derived from the 2015 American Census Survey. Logistic regression was used to examine perioperative characteristics by ADI and rurality. RESULTS: Compared to patients from the least deprived neighborhoods, patients from the most deprived neighborhoods were likely to be female (odds ratioOR 1.46, 95% confidence interval CI: 1.33-1.61), non-white (OR 1.36, 95% CI: 1.13-1.64), with education high school or less (OR 4.85, 95% CI: 4.35-5.41), be current smokers (OR 2.20, 95% CI: 1.61-2.49), have BMI>30 kg/m2 (OR 1.43, 95% CI: 1.30-1.57), more limitation on instrumental activities of daily living (OR 1.75, 95% CI: 1.55-1.97) and American Society of Anesthesiologists (ASA) score > II (OR 2.0, 95% CI: 1.11-1.37). There was a progressive association between the degree of area level deprivation with preexisting comorbidities. Patients from rural communities were more likely to be male, white, have body mass index (BMI)>30 kg/m2 and lower education levels. However, rurality was either not associated or negatively associated with comorbidities. CONCLUSION: TJA patients from lower SES neighborhoods have worse behavioral risk factors and higher comorbidity burden than patients from higher SES neighborhoods. Patients from rural communities have worse behavioral risk factors but not comorbidities.

Distribution and Correlates of Hip-Knee-Ankle Angle in Early Osteoarthritis and Preoperative Total Knee Arthroplasty Patients.

BACKGROUND: Several studies have investigated the distribution of hip-knee-ankle (HKA) angle in healthy populations; however, few have evaluated this metric in patients undergoing total knee arthroplasty (TKA). The purpose of this study is to compare HKA angle distribution in early and advanced knee osteoarthritis (OA) patients. METHODS: Full limb radiographs were used to measure HKA angle for 983 subjects from the Osteoarthritis Initiative (OAI) cohort and 4,901 pre-TKA patients from an institutional cohort. Measurements were made using a previously validated deep learning algorithm. Linear regression models were used to determine the association of HKA alignment angle with patient characteristics. RESULTS: The mean ± standard deviation HKA angle was -1.3° ± 3.2° in the OAI cohort and -4.1° ± 6.1° in the pre-TKA cohort. In the OAI cohort, normal alignment (64%) was the most common knee alignment followed by varus (29%), and valgus (7%). In pre-TKA patients, the most common alignment was varus (62%), followed by normal (27%) and valgus (11%). In pre-TKA patients, mean HKA angle in primary knee OA, post-traumatic knee OA, and rheumatoid arthritis patients were -4.3° ± 6.1°, -3.2° ± 6.4°, and -2.9° ± 6.1°, respectively. HKA angle was strongly associated (P < .001) with gender and body mass index. CONCLUSION: TKA patients have a wider alignment distribution and more severe varus and valgus alignment than individuals "at risk" for knee OA from the OAI cohort. These epidemiologic findings improve our understanding of HKA angle distribution and its correlation with demographic characteristics in early and late-stage arthritis.

Functional Outcomes and Health-Related Quality of Life Before and After Primary Total Knee Replacement for Patients From Diverse Geographic Regions.

BACKGROUND: The purpose of this study was to investigate whether patient-reported knee function and health status before and after primary total knee replacement (TKR) at an academic medical center differs among patients from diverse geographic regions. METHODS: We assessed patient-reported outcomes (PROs) as measured by the Oxford Knee Score (OKS) and EuroQoL-5D (EQ-5D) in 2855 TKR patients at preprimary and one year postprimary TKR procedure between January 1, 2012 and June 30, 2014. We compared the demographic characteristics, response rates, and changes in OKS, EQ-5D, and EQ visual analog scale among local, regional, and national patient groups. Patient- or hospital-related predictors of the postoperative scores were identified after controlling for preoperative scores on the PRO measures. RESULTS: Local patients had more comorbid conditions. Groups were similar in clinical outcomes such as length of stay at hospital, complication, and reoperation rates. Local, regional, and national patients had similar response rates and reported a similar level of knee function and health-related quality of life before and after TKR. Eighty nine percent had clinically important improvement on OKS, 69% on EQ-5D index, and 28% EQ visual analog scale, and there were no differences among groups in the proportions of clinically meaningful change. Better postoperative PRO scores were associated with older age, shorter hospital stay, fewer comorbidities, nonsmoking status, fewer complications, and private health insurance. CONCLUSION: Some patient characteristics such as comorbidities were greater in the local patient cohort versus the national cohort. Nevertheless, clinical outcomes and PROs were comparable across all geographic tiers.

A Multicenter Comparison of Complementary and Alternative Medicine (CAM) Discussions in Oncology Care: The Role of Time, Patient-Centeredness, and Practice Context.

BACKGROUND: Little is known about how complementary and alternative medicine (CAM) is discussed in cancer care across varied settings in the U.S. METHODS: In two practices affiliated with one academic medical center in southern California (SoCal), and one in the upper Midwest (UM), we audio-recorded patient-clinician interactions in medical oncology outpatient practices. We counted the frequency and duration of CAM-related conversations. We coded recordings using the Roter Interaction Analysis System. We used chi-square tests for bivariate analysis of categorical variables and generalized linear models for continuous variables to examine associations between dialogue characteristics, practice setting, and population characteristics with the occurrence of CAM discussion in each setting followed by multivariate models adjusting for clinician clustering. RESULTS: Sixty-one clinicians and 529 patients participated. Sixty-two of 529 (12%) interactions included CAM discussions, with significantly more observed in the SoCal university practice than in the other settings. Visits that included CAM were on average 6 minutes longer, with CAM content lasting an average of 78 seconds. In bivariate tests of association, conversations containing CAM included more psychosocial statements from both clinicians and patients, higher patient-centeredness, more positive patient and clinician affect, and greater patient engagement. In a multivariable model including significant bivariate terms, conversations containing CAM were independently associated with higher patient-centeredness, slightly longer visits, and being at the SoCal university site. CONCLUSION: The frequency of CAM-related discussion in oncology varied substantially across sites. Visits that included CAM discussion were longer and more patient centered. IMPLICATIONS FOR PRACTICE: The Institute of Medicine and the American Society of Clinical Oncology have called for more open discussions of complementary and alternative medicine (CAM). But little is known about the role population characteristics and care contexts may play in the frequency and nature of those discussions. The present data characterizing actual conversations in practice complements a much larger literature based on patient and clinician self-report about CAM disclosure and use. It was found that CAM discussions in academic oncology visits varied significantly by practice context, that the majority were initiated by the patient, and that they may occur more when visit time exists for lifestyle, self-care, and psychosocial concerns.

The Effects of Gross Cranial Nerve Invasion on Oncologic Outcomes in Patients with HPV(+)OPSCC.

OBJECTIVES: This study examines oncologic outcomes in patients with HPV-related oropharyngeal squamous cell carcinoma (HPV(+)OPSCC) who had evidence of gross cranial nerve invasion (CNI) identified at the time of surgery. STUDY DESIGN: Retrospective cohort study comparing demographics, clinical features, and outcomes of HPV(+)OPSCC patients with and without gross CNI. METHODS: Patients with biopsy proven HPV(+)OPSCC involving the base of tongue, tonsil, or unknown primary site, who underwent surgery as a part of their treatment between 1/1/2006-12/31/2020 (n = 874), were included in this study. Gross CNI was identified during operative intervention (n = 36). Statistical analyses were performed using SAS version 9.4 and R version 3.6.2. P-values <0.05 were considered statistically significant. RESULTS: HPV(+)OPSCC patients with gross CNI were nearly 5 times as likely to suffer death by cancer (HR = 5.41, 95% CI 2.51 to 11.67, p < 0.0001), over 4 times as likely to see disease progression (HR = 4.25, 95% CI 2.31 to 7.84, p < 0.0001), and nearly 5 times as likely to experience metastasis (HR = 4.46, 95% CI 2.20 to 9.06, p < 0.0001) when compared to patients without CNI. Patients with gross CNI had significantly lower overall survival, cancer-specific survival, progression-free survival, and distant-metastasis free survival (p < 0.0001). Patients with gross CNI were significantly more likely to present with higher clinical N stage, higher pathological N stage and extracapsular spread than patients without gross CNI. CONCLUSIONS: Our findings indicate that the presence of CNI is associated with significantly poorer oncologic outcomes in HPV(+)OPSCC patients. LEVEL OF EVIDENCE: 3 Laryngoscope, 134:170-177, 2024.

Underrepresented in Medicine Student Perspectives on the Selection of a Summer Research Program.

OBJECTIVES: Many summer research programs (SRPs) for URiM students exist; however, only a few have been established by otolaryngology programs, who have a unique opportunity to provide a diverse experience. We sought to assess URiM undergraduate student perspectives on the most valuable program features that influence decision-making and how this might be useful to otolaryngology programs seeking to establish pathway programs. MATERIALS AND METHODS: An externally facing REDCap survey composed of 37 questions in scaled, multiple-choice, and open-ended form. The survey was delivered to applicants via email over two time periods in April 2021 and February 2022. All survey responses were analyzed using descriptive statistics and categorized according to demographic information, program features, and advertising mechanisms. RESULTS: Seventy-one percent of our applicants self-identified as URiM. Over 60% experienced financial hardship, and 31% experienced educational hardship. The single most important feature when selecting a summer research program (SRP) was access to mentorship followed by clinical shadowing and research opportunities. When program features were aggregated into groups, institutional features were the most important, followed closely by funding features. Finally, students prefer to learn about SRPs through their university, followed by social media, despite many students learning about our program through other means. CONCLUSIONS: Paid programs with effective advertising, research, mentoring, and clinical shadowing are highly valued by URiM undergraduate students. Understanding student perspectives is critical for programs aiming to address the "leaky pipeline" while being deliberate in their support of underrepresented students.

Medical Maintenance Therapy Following Laser Excision in Patients With Granulomatosis With Polyangiitis (GPA)-Associated Subglottic Stenosis.

OBJECTIVE: To report on a series of patients with cANCA/PR3-positive, granulomatosis with polyangiitis (GPA)-associated subglottic stenosis (SGS) and evaluate response to medical maintenance therapy with rituximab versus other immunosuppressants following initial endoscopic laser excision. STUDY DESIGN: Retrospective chart review. SETTING: Tertiary academic center. METHODS: A retrospective chart review of patients with SGS and cANCA/PR3-positive GPA who received immunosuppressive maintenance therapy following endoscopic laser excision at our institution from June 1989 to March 2020 was performed. Data pertaining to patient demographics, clinical features, medications, and endoscopic laser procedures were collected. RESULTS: A total of 27 patients (15 women) with mean age (range) of 40 (19-59) years and mean (range) follow-up of 12.6 years (1.5-28.6) were identified. Sixteen patients (60%) had limited GPA. Six patients (24%) had previously received local intervention with open surgery (n = 1, 4%) or endoscopic techniques (n = 5, 20%). All patients experienced symptom improvement following initial CO2 laser excision at our institution without any procedural complications or adverse events. Following initial laser excision, 15 patients (60%) were treated with rituximab and 10 patients (40%) were treated with nonrituximab immunosuppressive agents. Patients treated with rituximab were less likely to recur (P = 0.040). Limited GPA was associated with an increased incidence of recurrence (P = 0.031). Median time (years) to recurrence (range) was 3.2 (0.3-19.3) and was not significantly associated with treatment or GPA subtype. CONCLUSION: Endoscopic CO2 laser excision is a safe and effective local intervention for GPA-associated SGS. Medical maintenance therapy with rituximab reduces risk of recurrence following initial laser excision relative to treatment with non-rituximab agents.

Symptom-Free Intervals Following Laser Wedge Excision for Recurrent Idiopathic Subglottic Stenosis.

OBJECTIVE: Analyze the duration of symptom-free intervals following laser wedge excision (LWE) for recurrent idiopathic subglottic stenosis (iSGS). Secondary aim includes evaluating the influence of patient-related or disease factors. STUDY DESIGN: Retrospective review. SETTING: Tertiary center. METHODS: Review of iSGS patients who underwent LWE between 2002 and 2021. LWE patients without prior airway surgery were labeled LWE primary (LWEP) and those with prior history of dilation were labeled LWE secondary (LWES). A conditional frailty repeated events model was used to analyze the median time to recurrence (MTR) for each nth recurrence. Secondary analysis included stratification by use of medical therapy and initial preoperative characteristics of scar (Myer-Cotton grade, distance between the glottis and superior-most aspect of scar, DGS; length of scar, DL). RESULTS: Two hundred and ten iSGS patients underwent LWE (131 LWEP, 79 LWES). The proportion of patients experiencing at least 1, 3, 6, and 12 recurrences, respectively, was 68.0% (n = 143), 40.7% (n = 85), 20.0% (n = 42), and 5.2% (n = 11). There was exponential time-shortening from the 1st to 12th recurrence (P < .0001). While MTR was 4.1 years after the first LWE, this fell to 2.8, 1.7, 1.0, and 0.7 years for the 2nd, 3rd, 6th, and 12th recurrences. Furthermore, LWEP patients experienced longer MTR than LWES counterparts within the first 6 recurrences (P < .01). There was no significant relationship between intersurgical interval and medication adherence, DL, DGS, or grade for recurrences beyond the first (P = .207, P = .20, P = .43, P = .16). CONCLUSION: Symptom-free intervals in iSGS shorten with each subsequent recurrence and LWE. The difference in MTR between LWEP and LWES groups was significant within the first 6 recurrences with LWEP having longer MTR.

Association Between Social Determinants of Health, Distance from Treatment Center, and Treatment Type with Outcomes in Human Papillomavirus Associated Oropharyngeal cancer.

OBJECTIVES: Social determinants of health (SDOH) can influence access to cancer care, clinical trials, and oncologic outcomes. We investigated the association between SDOH, distance from treatment center, and treatment type with outcomes in human papillomavirus associated oropharyngeal squamous cell carcinoma [HPV(+)OPSCC] patients treated at a tertiary care center. STUDY DESIGN: Retrospective review. METHODS: HPV(+)OPSCC patients treated surgically from 2006 to 2021 were selected from our departmental Oropharyngeal Cancer RedCap database. Demographic data, treatment, and oncologic outcomes were extracted. Distance was calculated in miles between the centroid of each patient zip code and our hospital zip code (zipdistance). RESULTS: 874 patients (89 % male; mean age: 58 years) were identified. Most patients (96 %) reported Non-Hispanic White as their primary race. 204 patients (23 %) had a high-school degree or less, 217 patients (25 %) reported some college education or a 2-year degree, 153 patients (18 %) completed a four-year college degree, and 155 patients (18 %) had post-graduate degrees. Relative to those with a high-school degree, patients with higher levels of education were more likely to live further away from our institution (p < 0.0001). Patients who received adjuvant radiation therapy elsewhere lived, on average, 104 miles further away than patients receiving radiation at our institution (Estimate 104.3, 95 % CI 14.2-194.4, p-value = 0.02). In univariable Cox PH models, oncologic outcomes did not significantly differ by zipdistance. CONCLUSIONS: Education level-and access to resources-varied proportionally to a patient's distance from our center. Patients travelling further distances for surgical management of OPSCC were more likely to pursue adjuvant radiation therapy at an outside institution. Distance traveled was not associated with oncologic outcomes. Breaking down barriers to currently excluded populations may improve access to clinical trials and improve oncologic outcomes for diverse patient populations.

Cross-sectional association between systemic metal concentrations and immune markers in patients with total joint arthroplasty.

Total joint arthroplasty (TJA) implants are composed of metal components. Although they are regarded safe, the long-term immunological effects of chronic exposure to the specific implant materials are unknown. We recruited 115 hip and/or knee TJA patients (mean age 68 years) who provided a blood draw for measurement of chromium, cobalt, titanium concentrations, inflammatory markers and systemic distribution of immune cells. We examined differences between the immune markers and the systemic concentrations of chromium, cobalt and titanium. CD66-b neutrophils, early natural killer cells (NK), and eosinophils were present in higher percentages in patients with chromium and cobalt concentrations greater than the median. The opposite pattern was observed with titanium where the percentages of CD66-b neutrophils, early NK, and eosinophils were higher in patients with undetectable titanium. Cobalt concentrations were positively correlated with a higher percentage of gamma delta T cells. Both chromium and cobalt concentrations were positively correlated with higher percentages of plasmablasts. Titanium concentrations were positively correlated with higher CD4 effector memory T cells, regulatory T cell count and Th1 CD4 helper cells. In this exploratory study, we observed altered distribution of immune cells in TJA patients with elevated systemic metal concentrations. Although these correlations were not strong, these exploratory findings warrant further investigation into the role of increased metals circulating in blood and its role in immune modulation.

Feasibility of Instituting a Clinical Otolaryngology Human Papillomavirus (HPV) Vaccination Program.

OBJECTIVES: To measure baseline human papillomavirus (HPV) vaccination rates among tertiary and community-based Otolaryngology - Head and Neck Surgery (Oto-HNS) clinic patients and to determine risk factors for under-vaccination. METHODS: Retrospective chart review of patients aged 9 to 26 years presenting to an Oto-HNS clinic from 2017 to 2019. Patients were considered complete for HPV vaccination if they received two doses of HPV vaccine with the first dose received before age 15 years or three doses of HPV vaccine otherwise. RESULTS: 8,532 unique patients met the criteria. At the index visit, 3,110 (36.5%) had completed the HPV series, 5,422 (63.5%) were due for one or more doses, with 4,981 (58.4%) eligible for vaccination at the time of their appointment. Of those dues, most (3,148/5,422 or 58%) were past due by age (≥13 years old). Of the 3,148 patients past due, 745 (23.7%) were partially vaccinated and 2,403 (76.3%) were vaccine naïve. Male sex and younger age were both independently associated with incomplete vaccination (p < 0.0001). CONCLUSION: This study demonstrates that the implementation of on-site HPV vaccination has the potential to increase the opportunities for vaccination among vaccine-eligible patients, especially among young males. Otolaryngologists have the potential to provide meaningful preventive services in the fight against HPV-mediated disease. LEVEL OF EVIDENCE: 3 Laryngoscope, 133:116-123, 2023.

Comparing Open Versus Rigid Endoscopic and Flexible Endoscopic Techniques for the Treatment of Zenker's Diverticulum.

OBJECTIVE: To describe the outcomes of patients undergoing open stapler versus transoral rigid and flexible endoscopic therapies for symptomatic Zenker's diverticulum. STUDY DESIGN: Single institution retrospective review. SETTING: Tertiary care academic hospital. METHODS: We retrospectively evaluated the outcomes of 424 consecutive patients who underwent Zenker's diverticulotomy via an open stapler, rigid endoscopic CO2 laser, rigid endoscopic stapler, rigid endoscopic harmonic scalpel, or flexible endoscopic technique from January 2006 to December 2020. RESULTS: A total of 424 patients (173 females, mean age 73.1 ± 11.2 years) from a single institution were included. A total of 142 patients (33%) underwent endoscopic laser treatment, 33 (8%) underwent endoscopic harmonic scalpel, 92 (22%) underwent endoscopic stapler, 70 (17%) underwent flexible endoscopic, and 87 (20%) underwent open stapler. All open and rigid endoscopic procedures and most of the flexible endoscopic procedures (65%) were performed under general anesthesia. The flexible endoscopic group had a higher percentage of procedure-related perforation, defined as subcutaneous emphysema or contrast leak on imaging (14.3%). The recurrence rates were higher in the harmonic stapler, flexible endoscopic, and endoscopic stapler groups at 18.2%, 17.1%, and 17.4%, respectively, and lower in the open group (1.1%). Length of hospital stay and return to oral intake were similar among groups. CONCLUSION: The flexible endoscopic technique was associated with the highest rate of procedure-related perforation, while the endoscopic stapler had the lowest number of procedural complications. Recurrence rates were higher among the harmonic stapler, flexible endoscopic, and endoscopic stapler groups and lower in the endoscopic laser and open groups. Prospective comparative studies with long-term follow-up are needed.

Diagnostic Delay in Human Papillomavirus Negative Oropharyngeal Squamous Cell Carcinoma.

OBJECTIVE: Failure to recognize symptoms of non-human papillomavirus-associated oropharyngeal squamous cell carcinoma (HPV(-)OPSCC) at presentation can delay diagnosis and treatment. We aim to identify patient factors and provider practice patterns that delay presentation and care in HPV(-)OPSCC. METHODS: Retrospective review at a tertiary care center. Patients with HPV(-)OPSCC receiving treatment from 2006 to 2016. Patients were excluded if their date of symptom onset or diagnosis was unknown after thorough review of the electronic medical record or their tissue was not tested for HPV or p16. Clinical data, workup, and care timelines were abstracted. Univariate and multivariable linear regressions were performed to determine associations between patient and provider factors and delays in care. RESULTS: Of 70 included patients, 52 (74%) were male and mean age was 60.5 (SD = 9.0). Median time to diagnosis was 69 days (IQR = 32-127 days), with a median latency of 30 days (IQR = 12-61 days) from symptom onset to first presentation and 19.5 days (IQR = 4-46 days) from the first presentation to diagnosis. Most patients visited at least 2 providers (n = 52, 74%) before diagnosis. Evaluation by 3 or more providers prior to diagnosis was associated with significant delays in diagnosis of nearly a year (357.7 days, p < 0.001) and being treated or prescribed analgesia prior to diagnosis was significantly associated with delays in diagnosis (p = 0.004) on univariate regression analysis. CONCLUSIONS: Delays in care related to evaluations by multiple providers and misdiagnosis prolonged time to diagnosis in HPV(-)OPSCC. Improved patient and provider education is necessary to expedite the diagnosis of HPV(-)OPSCC. LEVEL OF EVIDENCE: 4 Laryngoscope, 133:1394-1401, 2023.

Patterns and distribution of regional nodal involvement and recurrence in a surgically treated oropharyngeal squamous cell carcinoma cohort at a tertiary center.

OBJECTIVES: To investigate and describe the patterns of regional metastases and recurrences after surgical treatment of oropharyngeal squamous cell cancer (OPSCC). MATERIALS AND METHODS: Retrospective study of patients diagnosed with OPSCC from 2006 to 2021 at a tertiary referral center. Only patients treated with surgery including a neck dissection were included. Patients with unknown human papillomavirus (HPV) status, prior head and neck cancer, distant metastases, or synchronous head and neck cancer were excluded. RESULTS: A total of 928 patients were included. 89% were males, the average age was 58.6 years (range: 25.2-87.5), 874 (94%) were HPV(+), and 513 (55.3%) had a tonsil cancer. Among cN + patients, the most commonly involved levels at presentation were level II (85.2%), level III (33.3%), and level IV (9.4%). In cN0 patients, metastases were only observed in level II (16.2%) and level III (9.2%). Nodal recurrence occurred in 48 (5.2%) patients after a median time of 1.0 years (interquartile range: 0.6-2.0). Nodal recurrence incidence was similar in HPV(+) and HPV(-) patients (5.0% vs. 7.4%, p = 0.44). The most common levels for regional recurrence were ipsilateral level II (45.8%), contralateral level II (43.8%), and ipsilateral level V (25.0%). Multivariable analysis revealed that pN was a significant predictor for regional recurrence (p = 0.02). CONCLUSION: There is no difference in the distribution of regional metastases and recurrences in HPV(+) and HPV(-) OPSCC patients. Our findings align with the established understanding that regional metastases predominantly manifest in the ipsilateral level II-IV at presentation. Moreover, the data support the clinical recommendation to restrict elective neck dissection in cN0 patients to ipsilateral levels IIa and III, excluding level IIb. Regional recurrence is significantly associated with pN status.

Neighborhood-Level Socioeconomic Deprivation, Rurality, and Long-Term Outcomes of Patients Undergoing Total Joint Arthroplasty: Analysis from a Large, Tertiary Care Hospital.

Objective: To assess the impact of neighborhood-level socioeconomic status factors (area deprivation index [ADI] and rural classification) and their interaction with individual-level socioeconomic status (education-level) on long-term outcomes following total joint arthroplasty (TJA) surgery. Patients and Methods: This was a cohort study of 46,828 TJA surgeries performed on patients at a tertiary care hospital between January 1, 2000 and December 31, 2019. Cox proportional hazards models were used to examine the association between ADI and rurality and their interaction with individual-level education on the risk of periprosthetic joint infections, revision surgery, and mortality. Results: At the time of surgery, 2589 (6%) patients lived in the most deprived neighborhoods (ADI quintile >80%) and 10,728 (23%) lived in small isolated rural towns. Patients from the most deprived neighborhoods were more likely to experience revision surgery (hazard ratio, [HR], 1.39; 95% CI, 1.10-1.76) and mortality (HR, 1.24; 95% CI, 1.09-1.42). Patients from small rural towns were also more likely to undergo revision surgery (HR, 1.14; 95% CI, 1.01-1.28). The mortality risk was 13%, 18%, and 24% higher for patients in the 3 highest ADI quintiles than those from the lowest quintile. Education gradient was more notable in the least deprived neighborhoods than in the most deprived neighborhoods. Conclusion: Neighborhood disadvantage and rurality are negatively associated with the risk of revision surgery and both independently and in interaction with individual-level education with the risk of mortality. There is a need for population-level health interventions to mitigate area-based socioeconomic disadvantages in TJA.

Patient factors associated with COVID-19 loss of taste or smell patient factors in smell/taste loss COVID-19.

Objectives: Dysfunction in smell or taste is well recognized phenomenon in patients infected with SARS-CoV-2. This study aimed to quantify the incidence and associated co-morbidities of reported olfactory or gustatory dysfunction in patients who tested positive for SARS-CoV-2. Methods: From March 23, 2020 through July 31, 2020, 192,683 patients were tested for SARS-CoV-2 at Mayo Clinic. These patients with a positive test were contacted via telephone by physicians at Mayo Clinic and information gathered on patient demographics, comorbidities, symptoms and clinical risk stratification based on these factors. Results: Two thousand two hundred and fifty patients tested positive for SARS-CoV-2 (1.2%). Six hundred and sixty-seven (29.6%) of these patients reported loss of smell or taste. Factors found to be correlated with reporting loss of smell or taste on multivariate analysis were: younger age, female sex, or symptoms of chest pain or tightness, cough, or headache and lower clinical risk category. Coronary artery disease (CAD) was associated with not reporting loss of taste or smell. Conclusion: Of 2250 patients testing positive for SARS-CoV-2 at Mayo Clinic, 667 reported loss of taste and smell. Patients who reported loss of smell or taste were younger, female and more likely to report cough, chest pain, headache, or history of chronic obstructive pulmonary disease (COPD), but overall had fewer high-risk comorbidities. Those who were older, male, and a reported history of CAD were less likely to report chemosensory dysfunction. Our data are the largest single institution data reporting COVID-19 associated loss of smell or taste, and the first to associate COPD and CAD as factors that affect rates of reported chemosensory dysfunction. Level of evidence: IIB.
