Abstract Background Allostatic load (AL) is the physiologic “wear and tear” on the body from stress. Yet, despite stress being implicated in the development heart failure (HF), it is unknown whether AL is associated with incident HF events. Methods We examined 16,765 participants without HF at baseline from the REasons for Geographic and Racial Differences in Stroke (REGARDS) cohort. The main exposure was AL score quartile. AL was determined according to 11 physiologic parameters, whereby each parameter was assigned points (0–3) based on quartiles within the sample, and points were summed to create a total AL score ranging from 0–33. The outcome was incident HF event. We examined the association between AL quartile (Q1-Q4) and incident HF events using Cox proportional hazards models, adjusted for demographics, socioeconomic factors, and lifestyle. Results The mean age was 64 ± 9.6 years, 61.5% were women, and 38.7% were Black participants. Over a median follow up of 11.4 years, we observed 750 incident HF events (635 HF hospitalizations and 115 HF deaths). Compared to the lowest AL quartile (Q1), the fully adjusted hazards of an incident HF event increased in a graded fashion: Q2 HR 1.49 95% CI 1.12–1.98; Q3 HR 2.47 95% CI 1.89–3.23; Q4 HR 4.28 95% CI 3.28–5.59. The HRs for incident HF event in the fully adjusted model that also adjusted for CAD were attenuated, but remained significant and increased in a similar, graded fashion by AL quartile. There was a significant age interaction (p-for-interaction

Background More fragmented ambulatory care (ie, care spread across many providers without a dominant provider) has been associated with excess emergency department and inpatient care. We sought to determine whether more fragmented ambulatory care is associated with an increase in the hazard of incident stroke, overall and stratified by health status and by race. Methods and Results We conducted a secondary analysis of data from the REGARDS (Reasons for Geographic and Racial Differences in Stroke) study (2003–2016), including participants aged ≥65 years who had linked Medicare fee‐for‐service claims and no history of stroke (N=12 510). We measured fragmentation of care with the reversed Bice‐Boxerman index. We used Poisson models to determine the association between fragmentation and adjudicated incident stroke. The average age of participants was 70.5 years; 53% were women, 32% were Black participants, and 16% were participants with fair or poor health. Overall, the adjusted rate of incident stroke was similar for high versus low fragmentation (8.2 versus 8.1 per 1000 person‐years, respectively; P=0.89). Among participants with fair or poor self‐rated health, having high versus low fragmentation was associated with a trend toward a higher adjusted rate of incident strokes (14.8 versus 10.4 per 1000 person‐years, respectively; P=0.067). Among Black participants with fair or poor self‐rated health, having high versus low fragmentation was associated with a higher adjusted rate of strokes (19.3 versus 10.3 per 1000 person‐years, respectively; P=0.02). Conclusions Highly fragmented ambulatory care is independently associated with incident stroke among Black individuals with fair or poor health.

Home health aides (HHAs) provide care to many adults with heart failure (HF) in the home. As the demand for HHAs increases, there is a need to promote HHAs’ job satisfaction and retention. In this cross-sectional community-partnered study, we examined whether mutuality (e.g., quality of the HHA-patient relationship), is associated with job satisfaction among HHAs caring for adults with HF. Mutuality was assessed with the Mutuality Scale, which measures overall mutuality and its four domains (reciprocity, love and affection, shared pleasurable activities, and shared values). Our final sample of 200 HHAs was primarily female. The mean overall mutuality score was 2.92 out of 4 (SD 0.79). In our final model, overall mutuality and each of the four domains were associated with increased job satisfaction; however, only the shared pleasurable activities domain was significant (aPR: 1.15 [1.03–1.32]). Overall, mutuality may play a role in promoting job satisfaction among HHAs.

Objective Identify determinants of home care workers’ (HCW) self-efficacy in contributing to heart failure (HF) self-care. Methods Secondary analysis of a survey ( n = 328) examining characteristics of HCWs caring for adults with HF in New York. Self-efficacy assessed using Caregiver Self-Efficacy in Contributing to Self-Care Scale. Standardized scores range 0–100; ≥ 70 points indicate adequate self-efficacy. Characteristics determined by self-efficacy (low vs. adequate). Prevalence ratios with 95% confidence intervals (PR [95% CI]) were estimated using multivariable Poisson regression with robust standard errors. Results Home care workers with adequate self-efficacy had at least some prior HF training (55% vs. 17%, p < .001) and greater job satisfaction (90% vs. 77%, p = .003). Significant determinants for adequate self-efficacy were employment length (1.02 [1.00–1.03], p = .027), preparation for caregiving (3.10 [2.42–3.96], p < .001), and HF training (1.48 [1.20–1.84], p < .001). Conclusion Home care agencies and policy-makers can target caregiving preparation and HF training to improve HCWs’ confidence in caring for adult HF patients.

Introduction: Allostatic load (AL) is the physiologic “wear and tear” on the body from adapting to stress. AL is associated with mortality for diseases including cancer and diabetes. While stress has been implicated in the development of heart failure (HF), no studies have studied the association between AL and HF. Hypothesis: Higher allostatic load is associated with incident HF events. Methods: We examined 16,765 participants without suspected HF at baseline from the REGARDS cohort. The main exposure was AL score quartile. AL score was based on baseline heart rate, systolic blood pressure (BP), diastolic BP, waist circumference, glucose, total cholesterol, high density lipoprotein cholesterol, albumin, c-reactive protein, urine albumin to creatinine ratio, and cystatin C. Each parameter was assigned points (0-3) based on quartiles within the sample, and total AL score ranged from 0-33. The main outcome was incident HF hospitalization or HF death. Cox proportional hazards models were adjusted for baseline demographics, geographic residence, socioeconomic factors, and lifestyle/health habits. Results: The mean age of the sample was 64 + 9.6 years, 61.5% were women, and 38.7% were Black individuals. Over a mean follow up of 9.9 years, there were 750 HF events (635 incident HF hospitalizations and 115 incident HF deaths). AL score Q1 included scores 1-12, Q2 13-16, Q3 17-20, and Q4 21-33 (Figure). Compared to Q1, hazards for incident HF event increased with AL quartile (Q2 HR 1.29, 95% CI 0.93-1.79; Q3 HR 2.06, 95% CI 1.51-2.81; Q4 HR 3.65, 95% CI 2.68-4.97) in a fully adjusted model. Conclusion: AL was associated with incident HF events. This study supports a relationship between physiologic dysregulation due to maladaptive stress response and the development of HF.

The relationship between psychological stress and heart failure (HF) has not been well studied. We sought to assess the relationship between perceived stress and incident HF.We used data from the national REasons for Geographic And Racial Differences in Stroke (REGARDS) study, a large prospective biracial cohort study that enrolled community-dwellers aged 45 years and older between 2003 and 2007, with follow-up. We included participants free of suspected prevalent HF who completed the Cohen 4-item Perceived Stress Scale (PSS-4). Our outcome variables were incident HF event, HF with reduced ejection fraction events, and HF with preserved ejection fraction events. We estimated Cox proportional hazard models to determine if PSS-4 quartiles were independently associated with incident HF events, adjusting for sociodemographics, social support, unhealthy behaviors, comorbid conditions, and physiologic parameters. We also tested interactions by baseline statin use, given its anti-inflammatory properties.Among 25,785 participants with a mean age of 64 ± 9.3 years, 55% were female and 40% were Black. Over a median follow-up of 10.1 years, 1109 ± 4.3% experienced an incident HF event. In fully adjusted models, the PSS-4 was not associated with HF or HF with reduced ejection fraction. However, PSS-4 quartiles 2-4 (compared with the lowest quartile) were associated with incident HF with preserved ejection fraction (Q2 hazard ratio 1.37, 95% confidence interval 1.00-1.88; Q3 hazard ratio 1.42, 95% confidence interval 1.03-1.95; Q4 hazard ratio 1.41, 95% confidence interval 1.04-1.92). Notably, this association was attenuated among participants who took a statin at baseline (P for interaction = .07).Elevated perceived stress was associated with incident HF with preserved ejection fraction but not HF with reduced ejection fraction.

OBJECTIVES: To determine the prevalence and predictors of willingness to consider becoming a paid home care worker. DESIGN: Cross-sectional telephone-based survey study. SETTING AND PARTICIPANTS: 800 adult residents of New York State participating in the 2020 Empire State Poll, an annual survey conducted in English and Spanish using random digit dialing. METHODS: Willingness to consider working as a paid home care worker was analyzed as the main outcome. Survey questions also involved demographics and unpaid caregiving experience. We used multinomial logistic regression to examine associations between participant characteristics and willingness to be a paid caregiver. RESULTS: Participants had a mean age of 47.7 years (95% CI 45.4–50.0). Demographic information included 51.1% female gender, 65.4% White race, 13.4% Black race, 6.4% Asian or Pacific Islander, 14.8% another race, 19.1% Hispanic/Latino ethnicity, and 43.0% household income below $50,000 per year. A weighted 25.4% of participants would consider becoming a paid home care worker. In an adjusted model, willingness to be a paid home care worker was associated with younger age (OR 0.98, 95% CI 0.96–1.00, p=0.032), female gender (OR 2.46, 95% CI 1.35–4.46, p=0.003), Black or Other race (OR 2.40, 95% CI 1.11–5.17, p=0.026 and OR 3.13, 95% CI 1.30–7.54, p=0.011, respectively), Hispanic ethnicity (OR 2.26, 95% CI 1.06–4.81, p=0.035), household income below $50,000 per year (OR 2.00, 95% CI 1.03–3.88, p=0.040), and having provided unpaid family caregiving (OR 2.08, 95% CI 1.15–3.76, p=0.016). CONCLUSIONS AND IMPLICATIONS: A quarter of New Yorkers would consider working as a paid home care worker. Willingness to consider this occupation was associated with the demographic characteristics disproportionately represented in the current home care workforce. Improved working conditions and compensation could help attract and retain home care workers, thereby addressing the rising need for home care in the United States. BRIEF SUMMARY: In New York, 1) demographic characteristics mirroring the existing home care workforce and 2) experience providing unpaid care predicted willingness to consider working in paid home care.

Improving the production cost and yield in next-generation infrared focal plane arrays have drawn attention towards the growth of absorbing material on large-area low-cost substrates while maintaining high material quality. In this paper, we study the structural and optical properties of InAsSb bulk layers grown on lattice-mismatched semi-insulating GaAs and Ge-on-Si (Ge/Si) substrates using molecular beam epitaxy. We used X-ray diffraction (XRD) and temperature-dependent photoluminescence (PL) spectroscopy to determine the overall quality of these samples w. r.t the grown sample on the lattice-matched GaSb substrate. Analysis of the PL spectra's line shape reveals the ground state bandgap energy along with various optical transitions in each sample in the temperature range of 12 K–280 K. Furthermore, the temperature dependence of PL peak energy was analyzed, and the Integrated PL (IPL) intensity as a function of inverse temperature was used to compare the PL efficiency in each sample. The results indicate that PL is less dependent on the lattice mismatch-induced dislocations while it is mainly affected by the cracks originated from the difference in the thermal expansion coefficient of the Si substrate and the epilayer. The combination of optical and imaging analysis presented in this paper provides a deeper insight into each sample's material quality and predicts a promising path toward the application of alternative substrates in FPA imageries.

The relationship between subjective quality of life (QOL), clinical measures, and service utilization was measured in out-patients with schizophrenia. A total of 72 subjects completed the Quality of Life Interview and were also assessed by means of the Positive and Negative Syndrome Scale, a battery of neuropsychological tests, and two measures of social functioning. Use of psychiatric services over a 2-year period was ascertained from comprehensive records. Global subjective QOL was lower than patients' satisfaction with specific life domains. There were few significant correlations between satisfaction with, and objective measures of, specific life areas. In a multiple regression, patients' global subjective QOL was inversely related to their scores on the PANSS depression factor, and to the number of psychiatrist out-patient visits.

To distinguish between satisfaction with neighborhood and attachment to it, interviews were conducted in two neighborhoods in Baltimore, MD. Fifty residents responded to (a) direct measures of neighborhood satisfaction and attachment: and (h) measures of their evaluative beliefs about the neighborhood, their commitment-involvement to it, and their residential decisional processes. Correlation and multiple regression analyses (MRAs) indicated that neighborhood satisfaction and attachment are (a) significantly related; (b) have large affective components; and (c) are distinguishable responses, with attachment uniquely predicted by home ownership and extensiveness of social network.

A case study that describes the process of establishing mental health services in the medium-sized Howard County (Maryland) jail is presented. Built in 1878, the county jail provided virtually no rehabilitative services to its inmates until 1972. At that time, personnel from the Howard County Bureau of Mental Health began to gain access to the jail, establish rapport with the jail staff, assess the mental health needs of the inmates, and implement various programs to meet these needs. Implementation and development of services are described for the 12-year span between 1972 and 1984. The concept of providing community-based services has been accepted and incorporated into the value system and structure of the jail. It is concluded that the viability of programs depended upon interactions among continuation of strong leadership for each component of the rehabilitation program, acceptance of the value of these services by the jail administration and staff, and availability of community resources. The linkage between the jail and community agencies is discussed.

The ability of recombinant human tumor necrosis factor (rH-TNF-alpha) to induce regression of sarcoma 180 in vivo was evaluated. The tumor was cured by TNF in the course of 4 weeks. TNF inhibited proliferation of sarcoma 180 cells in vitro, which suggests a direct effect of TNF on tumor cells in vivo. In parallel to the TNF effect on tumor growth, some cell parameters in spleen were investigated. Activation of splenic macrophages was enhanced in vitro. This result suggests that macrophages may participate in the host defense against the tumor. In the first phase of therapy, TNF did not affect the proliferation of splenocytes but increased the transition of G0 into G1 cells. Furthermore, TNF normalized the tumor-induced increase of null cells in tumor-bearing mice. All parameters investigated in spleen reached normal values at the time of tumor regression. Our results suggest that various mechanisms may be involved in TNF-induced regression of sarcoma 180.

An anti-CD14 mAb RoMo-1 rapidly induces in human monocytes a transient oxidative burst activity as detected by chemiluminescence assay. Pretreatment of these cells with the mAb markedly suppresses the monocyte chemiluminescence response to opsonized zymosan. In addition, the antibody induces a significant increase of IL-1 production and secretion by mononuclear cells, comparable to a similar effect of rIFN-γ or LPS. Electron microscopy demonstrates internalization of the CD14 molecules after interaction with the mAb in a characteristic receptor-like manner.

Crude 3M KCl extracts prepared from tumor tissue and ascitic tumor cells of methylnitrosourea-induced fibrosarcoma of CBA mice or of a human stomach adenocarcinoma were gelfiltrated on Ultrogel AcA 34. Single fractions of these preparations were incubated with spleen cells of tumor bearing mice or blood peripheral lymphocytes. The response was detected by MEM-technique. Antigenic activities were found in molecular weight ranges from 200 to 300 kD (P1) and from 40 to 70 kD (P2). Single glycoproteins of the P1- and P2-fractions could be separated by affinity chromatography on immobilized D-galactose specific mistletoe lectin I, as detected by electrophoresis on microgradient gels (1.2-40%) or on SDS polyacrylamide slab gels. Especially the isolated glycoproteins of the P1-fractions are responsible for the observed antigenic reactivity, assayed in vitro by the MEM-technique and in vivo by foot pad swelling test.

- Abstract
Purpose: With the increasing utilization of endoscopic approaches for primary benign orbital tumor (PBOT) surgery, otolaryngologists and ophthalmologists are challenged with determining candidacy for endoscopic resection based on preoperative imaging. Our objective was to develop a semi-automatic modality for three-dimensional reconstruction of primary benign orbital tumors to shed light on their resectability., Methods: Patients with tumors from each ORBIT (Orbital Resection by Intranasal Technique) class were identified. Patients' preoperative imaging was obtained, and 3D slicer was utilized to segment the tumor with key anatomical structures, creating a three-dimensional model for each patient., Results: A model was generated for all five ORBIT classes. These models demonstrated the key findings differentiating classes such as whether a tumor is intraconal vs. extraconal, anterior or posterior to the intersection of the ophthalmic artery and optic nerve, or extends into the pterygopalatine and/or infratemporal fossa through inferior orbital fissure or through the superior orbital fissure., Conclusion: Our study utilized 3DSlicer to semi-automatically develop three-dimensional reconstructions of each class of benign orbital tumors as designated by ORBIT criteria. These reconstructions may provide additional quantitative and qualitative data regarding these tumors, their resectability, and the potential surgical approaches required.

- Abstract
Objectives: The primary objective of this prospective review was to compare quality of life between patients undergoing endoscopic and open skull base approaches., Study Type and Design: Prospective Review., Methods: Five centers recruited consecutive patients treated surgically for skull base neoplasms between 2012 to 2018. The Skull Base Inventory (SBI), Anterior Skull Base (ASB), and Sinonasal Outcome Test (SNOT-22) were administered up to 12 months post-operatively. Mean change from baseline scores were compared with univariable and multivariable analyses., Results: A total of 180 patients were included: 108 (60%) F and 72 (40%) M, of whom 126 (70%) underwent endoscopic and 54 (30%) underwent open approaches. Patients undergoing endoscopic approaches were more likely to have sellar or clival pathology (68 vs. 15%, p < 0.001). Those undergoing endoscopic approaches had better disease-specific quality of life at one year using the SBI and ASB (mean change from baseline = 7.2 vs. 0.69, p = 0.004; 5.8 vs. -1.1, p = 0.002), respectively. On multivariable analysis, endoscopic approach was associated with greater improvement in overall quality of life (mean difference in change scores from baseline = 6.5, p = 0.009), as well as endocrine (mean difference = 8.3, p = 0.011), neurologic (mean difference = 8.3, p = 0.012), visual (mean difference = 7.9; p = 0.032), financial (mean difference = 9.7, p = 0.03), and spiritual domain scores (mean difference = 4.0, p = 0.035). Subgroup analyses of pituitary and non-pituitary histopathologies demonstrated trends towards greater quality of life at 1-year compared to baseline in the endoscopic approach compared to the open group., Conclusions: Endoscopic approaches are associated with better quality of life compared to open approaches. However, baseline differences in histopathology between the group limit the direct comparison of the open and endoscopic approaches. Future studies with larger and more homogenous samples are required., Level of Evidence: Level IV evidence., Competing Interests: John de Almeida: Grant funding and honoraria from Cardinal Health, honoraria from EMD Serono.

- Abstract
Objectives: The COVID-19 pandemic affected the epidemiology of several diseases. This study aims to compare the incidence of surgically treated odontogenic sinusitis (ODS) before and during the COVID-19 pandemic and identify unique features., Methods: A retrospective chart review of patients who underwent at least maxillary antrostomy at a tertiary referral center was performed. The patients were divided into two cohorts: "pre-COVID" (March 2018 to February 2020) and "COVID" (March 2020 to February 2022). Data on demographics, comorbidities, and treatment interventions were collected and analyzed., Results: Of the 734 patients who underwent maxillary antrostomy, 370 (50.4%) were operated on during the COVID period, with a mean age of 53.1 ± 15.7 years. ODS was found as the etiology of 22 (6%) and 45 (12.2%) of the pre-COVID and COVID cases, respectively (p = 0.006). Although no difference was found in the incidence of diabetes (p = 0.9) or obesity (p = 0.7) between groups, a trend toward higher incidence of immunosuppression was found in the pre-COVID patients (18.2% vs. 0%, p = 0.06). A higher incidence of sphenoid sinus involvement (31.8% vs. 8.9%, p < 0.05) was identified in the pre-COVID group; however, no differences in ethmoid (86.4% vs. 86.7%, p = 0.999) or frontal sinus involvement (54.5% vs. 37.8%, p = 0.3) were found between the groups., Conclusion: There was an increase in the incidence of ODS during the first 2 years of the COVID-19 pandemic compared to the 2 years prior. Similar clinical characteristics were found in both groups. Future studies focusing on specific etiologies to explain ODS preponderance may help determine optimal treatment and prevention strategies., Level of Evidence: 3 Laryngoscope, 134:1597-1602, 2024., (© 2023 The American Laryngological, Rhinological and Otological Society, Inc.)

- Abstract
Objective: The presence of clinically detectable papillary thyroid carcinoma (PTC) metastases in the lateral neck is an indication for neck dissection (ND) and thyroidectomy. Although there is a consensus regarding the importance of therapeutic selective ND of involved levels II to IV in patients with clinically evident locoregional metastatic disease, the prognostic benefit of level V prophylactic ND remains debatable., Methods: All patients who underwent thyroidectomy with ND for metastatic PTC between 2006 and 2019 were included in a single-institution retrospective study. Preoperative characteristics at initial presentation, imaging workup, intraoperative findings, and the final histopathological reports were retrieved from the institutional database., Results: A total of 189 patients with locally advanced PTC were identified, of whom 22 (11.6%) patients underwent therapeutic selective ND at levels II to IV together with level V dissection due to clinical involvement. Comparison of the patients who were operated on level V to those who were not revealed no significant difference. The disease recurrence rate was 20.1% throughout an average follow-up of 5.1±3.1 years. No significant differences in recurrence rate were found between patients who underwent and those who did not undergo level V ND (22.7% vs 19.8%, P = .648). No recurrence at resected level V was detected during follow-up, while recurrence at level V was found in 4 (2.1%) patients who did not undergo level V dissection. Evidence of macroscopic and microscopic extrathyroidal extension was significant predictors of disease recurrence risk., Conclusion: There were no significant associations between level V dissection and risk for recurrence. Recurrence at level V was rare (4/189 patients, 2.1%). Our study's findings suggest a low prophylactic benefit of an elective level V ND. Elective level V ND should not be done routinely when lateral ND is indicated but should rather be considered after careful evaluation in high-risk patients.

- Abstract
Objective: Radiofrequency ablation (RFA) reliefs nasal obstruction and improves quality of life (QoL) in patients suffering from inferior turbinate hypertrophy (ITH). A substantial benefit was noted among patients suffering from Rhinitis Medicamentosa (RM), enabling ending decongestant spray abuse. Our aim was to establish the benefit from RFA with respect to QoL in patients suffering from ITH, due to the presence of RM., Study Design: Prospective cohort study., Methods: Prospective Cohort study, including patients suffering from ITH undergoing RFA between 9.2017 and 9.2019 in Tel Aviv Medical Center. The cohort was divided to RM and non-RM (including allergic, non-allergic) patients. The differences between the groups were compared before and after RFA, and included patients' complaints, clinical findings and QoL questionnaires (SNOT-22 & NOSE). In the RM group, the ability to wean from decongestants was also described., Results: Our data demonstrated subjective QoL improvement following RFA (88.9 %, N = 90). All RM patients withdrawaled from nasal decongestant spray. NOSE questionnaire demonstrated a significant improvement in QoL after RFA in the RM group (PV = 0.025). SNOT-22 did not demonstrate significant difference in QoL between RM and the reference group (PV = 0.1). Rates of MCID>8.3 were high, without significant difference between the groups (PV = 0.2)., Conclusion: RFA demonstrated effectiveness in achieving of withdrawal from decongestant spray in RM patients and may be a possible definitive treatment option for this group. The nasal obstruction component in SNOT-22 questionnaire & NOSE questionnaire showed improved QoL in comparison to controls. High QoL after RFA was established in our entire cohort., Competing Interests: Declaration of competing interest None., (Copyright © 2023 Elsevier Inc. All rights reserved.)

- Abstract
Background: The presence of cervical lymph node (LN) metastasis at the initial presentation of papillary thyroid carcinoma (PTC) constitutes an independent risk factor for disease recurrence, increases the risk for mortality, and impacts overall outcome. The 2016 American Joint Committee on Cancer raised the age cutoff for PTC staging from 45 to 55 years for better prediction of overall survival. Age > 55 years is considered a significant risk factor for a more aggressive and advanced disease with worse outcomes. We identified histopathological factors for disease recurrence in PTC patients younger and older than 55 years of age., Methods: Data on all patients who underwent thyroid surgery due to PTC between 2006 and 2018 in the Tel Aviv Sourasky Medical Center were retrieved for this retrospective cohort study. Patients with lymph node (LN) metastases were further investigated for preoperative presentation, pathological characteristics, and recurrence. A multivariate analysis was used to detect predictors for recurrence and patient outcome for each age-group., Results: Twenty-two of the 183 patients (12%) with PTC who met the inclusion criteria and had sufficient follow-up period sustained recurrence. The predictors of recurrence varied between the two age-groups. The size of thyroid lesions (p = 0.003) was identified as a risk factor in the older group, while the number of metastatic cervical LNs (p = 0.001) and the ratio of metastatic-to-total dissected cervical LNs (p = 0.027) were the main predictors of recurrence for the younger group., Conclusion: The histopathological factors predictive for disease recurrence differed among PTC patients younger and older than 55 years of age., (© 2022.

- Abstract
Objectives: Inferior turbinate hypertrophy (ITH) and nasal septum deviation are leading causes of chronic nasal obstruction. Radiofrequency ablation (RFA) of hypertrophic inferior turbinates is effective for improving quality of life (QOL). We aim to assess QOL among patients with nasal obstruction associated with ITH and major deviated nasal septum., Methods: A prospective cohort study comparing the difference in improved QOL among patients with and without septal deviation following RFA treatment between March 2016 and June 2019. The patients formed two groups according to their grade of septal deviation. Patients participating filled in QOL questionnaires (Sino-Nasal Outcome Test-22 [SNOT-22] and Nasal Obstruction Symptom Evaluation [NOSE]) Pre- and 2 months postprocedure., Results: All patients demonstrated QOL improvement with no significant difference between those with and those without any degree of deviated septum, as demonstrated by their responses to the SNOT-22 questionnaire ( p = .29), the NOSE questionnaire ( p = .93), and the degree of nasal obstruction (question 22 in the SNOT-22 questionnaire) ( p = .14)., Conclusion: We conclude that septal deviation to certain degree does not preclude treatment of ITH with RFA nor does it negatively affect subjective improvement of the patient's QOL. Both those with and those without septal deviation will benefit similarly with regards to subjective QOL improvement., Competing Interests: The authors declare no conflict of interest., (© 2022 The Authors.

- Abstract
Background: After diagnosing well-differentiated thyroid cancer (WDTC), assessment of the risk for disease-specific recurrence is essential for deciding between hemi-thyroidectomy (HT) and total thyroidectomy (TT). The American Thyroid Association (ATA) 2015 guidelines suggest that patients with 1-4 cm WDTC without suspicious features may be suitable for HT. Patients' preoperatively determined risk levels are re-stratified according to surgical and final histopathological findings. The incidence and clinical implications of high-risk features discovered postoperatively in patients with preoperatively determined low-risk WDTC are yet to be better defined., Methods: Thyroidectomies performed in the Tel-Aviv Sourasky Medical Center (TASMC) [2006-2018] were included. Patients with 1-4 cm WDTC without evidence of positive cervical lymph nodes, invasion to adjacent structures, or high-risk cytology were considered at low risk for disease-specific recurrence-suitable for lobectomy. Patients were stratified according to their risk for disease-specific recurrence, pre- and postoperatively, and the rate of completion thyroidectomy was determined., Results: In total, 301 (21%) patients were preoperatively stratified as low risk. Forty-six of them (15%) were re-stratified postoperatively as intermediate-to-high-risk. There were no significant differences in the characteristics of the patients who maintained their original stratification to patients who were upscaled to a higher risk level postoperatively., Conclusions: We report a 15% rate of postoperative risk escalation of patients who required completion thyroidectomy according to current ATA guidelines. In our opinion, this rate of postoperative WDTC upscaling of risk requiring more radical surgery than originally planned, is acceptable. Meticulous preoperative personalized evaluation by an experienced multidisciplinary dedicated team is essential., Competing Interests: Conflicts of Interest: All authors have completed the ICMJE uniform disclosure form (available at https://dx.doi.org/10.21037/gs-21-105).

- Abstract
Objective Reconstruction after open surgery of anterior skull base lesions is challenging. The fascia lata graft is our workhorse for achieving dural sealing and preventing cerebrospinal fluid leak and meningitis. This study seeks to analyze the donor and recipient site complication rates after fascia lata reconstruction. Methods This is a retrospective review of all open anterior skull base operations in which a double-layer fascia lata graft was used for the reconstruction of the defect from 2000 to 2016 at the Tel-Aviv Sourasky Medical Center, a tertiary referral center in Israel. Results Of the 369 patients operated for skull base lesions, 119 underwent open anterior skull base surgery and were reconstructed with a fascia lata graft. The patients' mean age was 47.1 years, and 68 (57.1%) were males. The overall postoperative early and late donor site complication rates were 6.7% ( n = 8) and 5.9% ( n = 7), respectively. Multivariate analysis found minor comorbidities and persistent/recurrent disease as being predictors for early-term complications. The overall postoperative early central nervous system (CNS) complication rate was 21.8% ( n = 26), while 12.6% ( n = 15) of the patients had late postoperative CNS complications. Conclusion Reconstruction of open anterior skull base lesions with fascia lata grafting is a safe procedure with acceptable complication and donor site morbidity rates., Competing Interests: Conflict of Interest None declared., (Thieme.

- Abstract
Surgery is the preferred treatment of benign parotid lesions, but it carries a risk of complications. Therefore, the approach toward the surgery of these lesions should seek to avoid complications. There are no guidelines or recommendations for when not to operate. Integration of comorbidities and other factors shift the scales from surgery toward observation in a small subset of patients presenting with parotid tumors. When observation is chosen, the patient should be followed frequently and cautiously, and the surgeon should be prepared to change strategy to surgical excision if in doubt., Competing Interests: Conflict of Interest Disclosures The authors have no funding, financial relationships, or conflicts of interest to disclose., (Copyright © 2021 Elsevier Inc.

- Abstract
Introduction Endoscopic endonasal surgery (EES) has become the preferred approach for pituitary tumor resection. Nevertheless, research on quality of life related to pituitary adenoma surgery is scarce. Objective The aim of the study is to evaluate short-term quality of life in patients after endoscopic endonasal resection of pituitary tumors and to find predictors for poor quality of life (QOL) outcome. Materials and Methods A prospective cohort study was conducted, including all patients who underwent EES for pituitary tumors in a tertiary medical referral center. Recruited patients completed the Anterior Skull Base Disease-Specific QOL (ASBS-Q) questionnaire and the Sinonasal Outcome Test 22 (SNOT-22) questionnaire before surgery, 2 and 4 to 6 months after surgery. Demographic and clinical data was collected. Results Our study included 49 patients. The overall ASBS-Q scores significantly improved 4 to 6 months after surgery (4.46 vs. 4.2, p < 0.05). We found a significant improvement in QOL related to emotional state 2 months post surgery (4.41 vs. 3.87, p < 0.05), which became borderline significant 4 to 6 months post surgery. There was a significant improvement in pain (4.5 vs. 4.08, p < 0.05) and vitality (4.43 vs. 4.16, p < 0.05) domains 4 to 6 months post surgery. SNOT-22 scores did not change significantly postoperatively. Factors such as secreting and non-secreting tumors, tumor size, intraoperative cerebrospinal fluid leak, gross tumor resection, endocrine remission, and the use of nasoseptal flap reconstruction did not have a significant effect on QOL. Conclusion We found that patients after EES reported improved QOL 4 to 6 months post surgery. Specific improvement was noted in the QOL related to pain and vitality., Competing Interests: Conflict of Interest None declared., (Thieme. All rights reserved.)

- Abstract
Introduction Isolated nasal obstruction (INO) is a common complaint of multiple etiology. The preoperative evaluation of patients presenting with nasal obstruction and deviated nasal septum (DNS) does not typically include imaging. The benefits of performing computed tomography (CT) in the preoperative setting are inconclusive. Objective Assessing the contribution of preoperative CT to the surgical treatment of non-sinusitis patients presenting with INO and DNS. Methods A retrospective cohort study on patients referred to surgery for nasal obstruction due to DNS or turbinate hypertrophy between 2006 and 2015. Data was retrieved from patients' medical charts. The CT scans and clinical data were reassessed by a second surgeon blinded to the patients' clinical course. Results Seventy of the 843 patients (8.06%) who underwent endoscopic sinonasal procedures during the study period had presented with INO and met the inclusion criteria. Thirty-eight (55.88%) of them underwent CT scans during their preoperative assessment. Modification of the initial preoperative planning based on the radiological findings was required in 32 cases (84.2%). When reassessed by a second blinded surgeon, 58% of cases required surgical modification rather than classical submucosal resection of nasal septum and turbinate reduction ( P = 0.048). Conclusion Computed tomography was found beneficial in the preoperative planning for patients with INO. The original surgical plan based upon physical examination findings was modified based on radiological findings in 84.2% of the patients., Competing Interests: Conflict of Interests The authors have no conflict of interests to declare., (Fundação Otorrinolaringologia.

- Abstract
Background: Papillary thyroid cancer (PTC) usually metastasizes via lymphatic channels in a sequential fashion, first to the central compartment, followed by the lateral neck. PTC patients diagnosed with lateral neck disease (N1b) without proof for central involvement traditionally undergo prophylactic central neck dissection (pCND). However, substantial evidence on outcomes to support this approach is lacking., Materials and Methods: We conducted a dual center retrospective study to compare the rate of central neck recurrence between N1b PTC patients undergoing pCND and those spared pCND. All patients diagnosed with N1b PTC who underwent total thyroidectomy and lateral neck dissections with or without pCND between January 1998 and December 2015 were included in this study. The rates of central neck recurrences were compared between the groups., Results: The 111 patients who met the inclusion criteria were 44 females (39.6%) and 67 males (60.4%), with a mean age of 50.2 ± 17.7 years, and a mean follow-up of 10.2 ± 5.3 years. Sixty patients (54.1%) underwent a pCND and 51 patients (45.9%) did not (non-pCND). During follow-up, 18 patients (16.2%) had level VI recurrences, 13 in the pCND group and 5 in the non-pCND group. Cox-regression models with propensity scoring did not reveal any inclination or an advantage for performing pCND., Conclusion: The present study demonstrated no advantage in performing pCND to prevent central neck recurrence among PTC patients with lateral neck involvement only. These findings question the need for pCND in patients without clinical evidence of central neck disease., (© 2020 Wiley Periodicals LLC.)

- Abstract
Purpose: The skull base inventory (SBI) was developed to better assess health-related quality of life (HR-QOL) in patients with anterior and central skull base neoplasms treated by endoscopic and open approaches. The primary objective of this study was to prospectively assess the psychometric properties of the SBI., Methods: This study is part of a multi-center study of patients undergoing endoscopic and open procedures completed between 2012 and 2018. Participants were eligible if they were over 18 years of age; had benign or malignant anterior, antero-lateral, or central skull base tumors; and required either an open or endoscopic skull base surgical approach. In order to assess the psychometric properties of the SBI, patients completed the instrument at six time points (preoperative, 2 weeks, 3 months, 6 months, 12 months postoperative). Patients also completed the Anterior Skull Base (ASB) questionnaire and the Sinonasal Outcome Test (SNOT-22) to allow comparison to the SBI., Results: One hundred and eighty-seven patients were included across five centers, with 121 having an endoscopic procedure. Internal consistency (Cronbach's alpha = 0.95) and test-retest at 12 months and 12 months plus 2 weeks (intraclass correlation > 0.90) were excellent. Concurrent validity was demonstrated by very strong correlation between total SBI scores and ASB scores (r = 0.810 to 0.869, p < 0.001) and moderate correlation between nasal domain SBI scores and SNOT-22 scores (r = - 0.616 to - 0.738, p < 0.001). Convergent validity was demonstrated by moderate correlation between change in SBI scores and global QOL change (r
s = 0.4942, p < 0.001). The minimally important clinical difference (global HR-QOL change of "a little better" or "a little worse") was 6.0., Conclusion: The SBI questionnaire is reliable and valid for patients treated by both endoscopic and open approaches and can be used for assessment of HR-QOL in these settings.- Published

- Abstract
Objective: Lateral and central compartments cervical lymph nodes metastases are common among patients with papillary thyroid carcinoma (PTC). Elective level VI neck dissection during thyroidectomy and lateral neck dissection (LND) for the treatment of PTC with lateral compartment lymph node metastases is controversial because of the uncertain benefit in clinical outcomes and increased risks of surgical morbidity. We aimed to determine the potential benefit of elective level VI neck dissection in patients with cN1 papillary thyroid carcinoma (PTC) by investigating the rate and pattern of locoregional recurrence in PTC patients who underwent total thyroidectomy and therapeutic lateral node dissection (LND; levels II-IV) without elective level VI dissection., Methods: A retrospective cohort study. Data on demographics, clinical presentation and workup, intraoperative and pathological report, postoperative course, adjuvant therapy, recurrence patterns, and overall survival were retrieved from the medical charts of patients who underwent thyroid surgery in our hospital between January 2006 and December 2017., Results: A total of 1415 thyroidectomies were performed during the study period, of which 802 (56.67%) were for PTC. Of those PTC patients, 228 (28.42%) also underwent LND (levels II-VI) during the same thyroidectomy procedure. Thirty-four (14.91%) of those 228 patients, underwent total thyroidectomy with therapeutic lateral ND II-IV without elective level VI ND. During the follow-up period, five (14.7%) of the latter cohort were diagnosed with recurrence in central neck (level VI) lymph nodes, and four of them (11.7%) were diagnosed with ipsilateral recurrence at level VI., Conclusion: Our results revealed 11.7% rate of clinically significant recurrent disease in ipsilateral level VI which, in our opinion, does not justify routine prophylactic level VI ND dissection when the ipsilateral lateral neck is operated for metastases.

- Abstract
Objectives: Reconstruction of surgical defects by free tissue transfer following resection of head and neck tumors in children are sparse. This study aims to assess the feasibility and safety of free flap reconstruction following surgical ablation of head and neck and skull base tumors in children based on our experience and the recent literature., Methods: Data from medical files of all children and adolescents <18 years of age who underwent free flap reconstruction following resection of head and neck and skull base tumors at our tertiary center between 2000 and 2018 were retrospectively reviewed. Data on early and late complications at the primary and donor sites, functional and aesthetic outcome, and tumor control were analyzed., Results: Twenty-four children (mean age 11.3 ± 5.1 years) were enrolled. Early complications occurred in 14 (56%) and late complications occurred in 8 (32%) of the procedures, with surgical intervention required in 4 (16%). Prior chemoradiation, sarcoma, non-reanimation procedures, and the use of rectus abdominis free flaps were associated with higher complication rates. The final functional and cosmetic outcomes, including mastication, deglutition, and speech, were satisfactory in all patients with one exception., Conclusions: Free flap transfer is a safe and feasible technique for reconstructing head and neck and skull base defects following surgical excision of tumors in children. Early identification and precautionary measures against the effects of potential causes of complications may improve outcome. Larger international cohort studies are warranted., (Copyright © 2020.

- Abstract
Objective Despite its technical feasibility, anterior skull base surgery still carries the risk of severe postoperative complications, morbidity, and mortality. The reported rate of complications has diminished over the past two decades, but they continue to pose various challenges. This study aims to report late complications in a relatively large series of patients who underwent open anterior skull base surgery, and to propose methods for averting such complications. Methods Retrospective chart review of all patients who underwent anterior open skull base surgery between 2000 and 2016 in a university-affiliated tertiary referral cancer center. Results There were 301 operations, of which 198 (65.8%) were for benign disease and 103 (34.2%) were for malignant tumors. The male-to-female ratio was 1.4:1, and the mean age was 44.8 years. Delayed complications occurred in 85 patients (28.2%): 31 (10.3%) involved wounds, 18 (13.9%) involved the central nervous system, and 14 (4.6%) involved the orbit. Multivariate analysis found malignant pathology, intracranial extension, and previous radiochemotherapy as predictors for the development of a delayed complication. The patients who were operated in the later study period (after 2007) had lower rates of all three types of complications compared with the earlier study period. Conclusion Delayed complications following skull base surgery are in decline. This is mainly due to the advancement in imaging studies, surgical techniques, development of sophisticated reconstructive procedures, and the cooperation of multidisciplinary teams. We attribute the reduction in our department to our revised treatment protocol which is presented herein, with emphasis on averting the occurrence of these complications.

- Abstract
Purpose: Acute supraglottitis (SG) can potentially lead to rapid airway obstruction. The last few decades have witnessed a shift towards a more conservative approach in airway management of adult SG. This study aims to evaluate this watchful approach based on a large case series combined with a high-level meta-analysis of all reports in the English literature., Methods: Retrospective case series and meta-analysis. The medical records of all adult patients diagnosed as having SG who were hospitalized in a large-volume tertiary referral center between January 2007 and December 2018 were reviewed. A meta-analysis was conducted on all English literature published between 1990 and 2018., Results: A total of 233 patients (median age 49.1 years, 132 males), were admitted due to acute SG during the study period. No airway intervention was required in 228 patients (97.9%). Five patients (2.1%) required preventive intubation, and two of them (0.9%) were later surgically converted to a tracheotomy. Patients who required airway intervention had higher rates of diabetes (P = .001), cardiovascular diseases (P = .036) and other comorbidities (P = .022). There was no mortality. The meta-analysis revealed that the overall intubation rates random effects model was 8.8% [95% confidence interval (CI) 4.6%-14.0%] and that the tracheotomy random effects model was 2.2% (95% CI; 0.5%-4.8%). The overall mortality rate was 0.89%., Conclusions: This study provides evidence of low rates of surgical airway intervention in patients diagnosed with SG worldwide. A conservative approach in adult SG is safe and should be advocated., Level of Evidence: 2., (Copyright © 2020. Published by Elsevier Inc.)

- Abstract
Introduction: Several surgical procedures have been described for the treatment of respiratory distress secondary to vocal fold immobility (VFI), but the contribution of posterior cordotomy (PC) to tracheostomy weaning or prevention has not been studied in depth, particularly in the acute setting. The objective of this study was to show the effectiveness of PC to relieve dyspnea, prevent the need for tracheostomy, and enable decannulation in patients with VFI., Methods: We conducted a retrospective study and reviewed the medical records of all patients whose dyspnea warranted surgical intervention from January 2013 to January 2018. Data were retrieved on epidemiology, etiology, and duration of VFI, tracheostomy dependence, success in decannulation from tracheostomy or respiratory relief, number of procedures until decannulation, and complications., Results: Twelve suitable patients were identified of whom eleven had bilateral VFI and one had unilateral VFI. Five were tracheostomy-dependent. Ten patients underwent unilateral PC, and two patients underwent bilateral PC. All the patients experienced respiratory relief, eleven after a single PC and one after two PCs. All tracheostomy-dependent patients were decannulated. The mean follow-up after PC was 24.55 months during which none of the patients required a re-tracheostomy and three patients required revision of the PC. There were no surgical complications. Postoperatively, eight patients (67%) experienced a breathy voice and three patients (25%) had dysphagia for fluids. No patient had aspiration pneumonia., Conclusions: We conclude that PC is an easy, safe, and effective procedure for tracheostomy weaning and respiratory relief in patients with VFI. A revision PC may be indicated in some patients. A breathy voice is to be expected, and a few patients will experience dysphagia to fluids that may be addressed by instructing the patient to use a fluid thickener and take small sips., Competing Interests: Conflict of interest: The authors declare that they have no competing interests.

- Abstract
Purpose: Acute supraglottic laryngitis (ASL) is manifested by supraglottic inflammation that has the potential for rapid and fatal airway obstruction. Complete/incomplete vocal fold immobility (VFIm) in the setting of ASL may contribute to airway obstruction. The rate of VFIm complicating ASL is not known, and it is not clear whether its occurrence alters the course and the management of ASL, particularly the need to secure the airway (by endotracheal intubation/tracheostomy). This study seeks to describe the natural history of VFIm associated with ASL (ASLIm) and to determine the added effect of VFIm on ASL severity, management, and the need for intervention to secure the airway., Methods: This is a retrospective cohort study in a tertiary referral center. The medical records of all patients hospitalized due to ASL between January 2007 and December 2016 were reviewed., Results: Of the 214 patients admitted due to ASL, VFIm was identified in 9 (4.2%). The VFIms resolved within 1-90 days in all 8 patients with available follow-up of 1-3 months. One patient required endotracheal intubation. The 9 ASLIm patients had significantly higher rates of hoarseness and a history of diabetes mellitus. There was no group difference in the need to secure the airway., Conclusions: VFIm is an apparently uncommon finding among patients with ASL. It appears to be usually transient, short-lasting, and full recovery can be expected. VFIm did not alter the ASL course, nor did it put our patients at increased risk for the need for intervention to secure the airway., Level of Evidence: 4.

- Abstract
Introduction The steady increase in average life expectancy has led to a rise in the number of referrals of elderly patients for major operations. It is not clear whether age itself is a risk factor for morbidity and mortality after skull base operations. We investigated a possible link among a cohort of patients older than 80 years of age who underwent those surgeries in our department. Methods We conducted a retrospective analysis of all patients who underwent skull base surgery at the TASMC (Tel Aviv Sourasky Medical Center) between 2000 and 2016. Results A total of 369 patients underwent open skull base surgeries in our institution, and 13 were patients older than 80 years. The median age of the octogenarians was 83.4 (range 80-89), and the male-to-female ratio was 7:6. Twelve patients had major systemic comorbidities. Four patients had major complications associated with surgery: three had early wound complications, and one each had early central nervous system complications, early and late systemic complications, and late orbital complications. This complication rate is comparable to that of our younger group of 356 patients. The overall survival rate was measured for 30 days, 1 year, and 3 years, and it was not significantly different between the octogenarians and that of the younger patients. Further comparison of the elderly group with 13 matched younger patients revealed no difference of morbidity and mortality between the two groups. Conclusions Despite their systemic comorbidities, the morbidity and mortality rates associated with skull base surgery in octogenarians appear to be comparable to that of younger patients undergoing the same procedures.

- Abstract
Objectives/hypothesis: Anterior skull base operations pose the risk for postoperative cerebrospinal fluid (CSF) leak. Routine lumbar continuous drainage catheter (LD) placement is intended to decrease CSF leaks and central nervous system (CNS) complications, but there are no sound evidence-based data on its efficacy. The primary goal of this study was to review CNS complications following anterior open skull base surgery and their association with LD placement. The secondary goal was to define predictors for the development of early CNS complications., Study Design: Retrospective case series., Methods: We conducted a retrospective analysis of all patients who underwent anterior skull base surgery between 2000 and 2016 at the Tel Aviv Sourasky Medical Center, an Israeli tertiary referral center., Results: A total of 226 patients underwent open skull base surgery, of whom 118 had elective perioperative continuous LD insertion and 108 did not. Delayed complications were defined as those occurring more than 30 days after the index operation. Thirty-one (26%) patients in the LD group had early CNS complications compared with only two (1.6%) in the non-LD group, whereas 13 (11%) of the former patients had late CNS complications compared with four (3%) of the latter patients. Early systemic and late wound complications were also significantly more numerous in the LD group. On multivariate analysis, elective LD insertion and intracranial tumor extension were found to be predictors for developing early CNS complications., Conclusions: The placement of continuous LDs might increase the risk of developing early and late CNS complications after open anterior skull base surgery., Level of Evidence: 4 Laryngoscope, 128:2702-2706, 2018., (© 2018 The American Laryngological, Rhinological and Otological Society, Inc.)
