Introduction: A long-term goal of our group is to develop proteomic-based approaches to the detection and use of protein biomarkers for improvement in diagnosis, prognosis, and tailoring of treatment for head and neck squamous cell cancer (HNSCC). We have previously demonstrated that protein expression profiling of serum can identify multiple protein biomarker events that can serve as molecular fingerprints for the assessment of HNSCC disease state and prognosis.Methods: An automated Bruker Daltonics (Billerica, MA) ClinProt matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) mass spectrometer was used. Magnetic chemical affinity beads were used to differentially capture serum proteins prior to MALDI-TOF analysis. The resulting spectra were analyzed using postprocessing software and a pattern recognition genetic algorithm (ClinProt 2.0). An HNSCC cohort of 48 sera samples from 24 patients consisting of matched pretreatment and 6 to 12 month posttreatment samples was used for further analysis. Low-mass differentially expressed peptides were identified using MALDI-TOF/TOF.Results: In the working mass range of 1,000 to 10,000 m/z, approximately 200 peaks were resolved for ionic bead capture approaches. For spectra generated from weak cation bead capture, a k-nearest neighbor genetic algorithm was able to correctly classify 94% normal from pretreatment HNSCC samples, 80% of pretreatment from posttreatment samples, and 87% of normal from posttreatment samples. These peptides were then analyzed by MALDI-TOF/TOF mass spectometry for sequence identification directly from serum processed with the same magnetic bead chemistry or alternatively after gel electrophoresis separation of the captured proteins. We were able to compare this with similar studies using surface-enhanced laser desorption ionization (SELDI)-TOF to show this method as a valid tool for this process with some improvement in the identification of our groups.Conclusions: This initial study using new high-resolution MALDI-TOF mass spectrometry coupled with bead fractionation is suitable for automated protein profiling and has the capability to simultaneously identify potential biomarker proteins for HNSCC. In addition, we were able to show improvement with the MALDI-TOF in identifying groups with HNSCC when compared with our prior data using SELDI-TOF. Using this MALDI-TOF technology as a discovery platform, we anticipate generating biomarker panels for use in more accurate prediction of prognosis and treatment efficacies for HNSCC.

Background: Conventional parathyroidectomy, as practiced only 10 years ago, has given way to considerable change, largely as a result of the evolution of technology. Several of these important technologies include radio-guided surgery, ultrasound imaging, high-resolution endoscopy, and rapid intraoperative parathyroid hormone (IOPTH) monitoring. Modern parathyroid surgeons should maintain familiarity with the appropriate role of these approaches. Study Design: Evidence-based analysis of state-of-the-art approaches to the diagnosis and management of primary hyperparathyroidism. Methods and Materials: Four distinct technologies are analyzed in detail, with particular attention to their impact on the practice of parathyroid surgery. These include radio-guided surgery, ultrasound imaging, high-resolution endoscopy, and IOPTH. Results: Each of the technologies examined has substantial value in the current practice of parathyroidectomy. Judicious implementation of these technologies will vary from practice to practice. Radio-guided surgery may obviate the need for IOPTH monitoring, therefore resulting in the fastest procedural times. Ultrasound imaging is useful as an adjunct to sestamibi scanning to localize adenomatous parathyroid glands. Endoscopic techniques facilitate visualization through small openings and may help surgeons achieve minimal access incisions. Finally, the use of IOPTH is a useful adjunct to directed explorations, and it imparts confidence that all hyperfunctioning parathyroid tissue has been removed. Conclusions: The practice of parathyroid surgery has undergone tremendous change in the past decade, and this change has largely been a technology-driven phenomenon. Acquisition of familiarity and skill with these new technologies will be necessary for the endocrine head and neck surgeon wishing to stay abreast of modern surgical techniques and provide quality care.

Objective: Fluorodeoxyglucose (FDG) whole body positron emission tomography (PET) scan may show clinically occult second lesions. Such lesions in the thyroid are increasingly common. There are several recent reports of a high probability of malignancy in these lesions ranging from 14% to 63%. Study Design and Setting: This is a retrospective review of 15,711 PET scans at a multi-disciplinary thyroid clinic at a tertiary care university medical center. Twenty-two patients were referred with thyroid PET "incidentalomas." The review included 18 FDG-PET scans, ultrasound guided fine needle aspiration biopsies, and thyroid surgery pathology. Aspiration cytology or pathology were the main outcome measures. Results: Three patients had malignancy of the PET-positive thyroid lesions. Papillary thyroid micro carcinomas were detected in four of the specimens that showed a benign pathology of the dominant nodule. Conclusion: Our experience shows a 14% malignancy rate for the dominant (imaged) nodule and a total malignancy rate of 32% when the incidental micro carcinomas are included. Both of these rates are significantly lower than results published previously. [ABSTRACT FROM AUTHOR]

Wegener's granulomatosis (WG) is a rare, idiopathic, systemic vasculitis of small vessels that manifests in multiple organ systems. Otorhinolaryngic manifestations of this disease include recurrent sinusitis and relapsing polychondritis. Periocular involvement is also a well-documented location of Wegener's disease. We present the case of a 13-year-old girl with severe WG who developed multiple recurrent orbital infections. She underwent multiple incision and drainage surgeries of each orbit and multiple courses of intravenous antibiotics. The patient persistently reaccumulated purulence in her nasolacrimal duct system and was referred to an oculoplastic surgeon for evaluation of these recurrent infections. The diagnosis of dacryocystitis as a complication of WG was made. This unique case represents a patient with severe WG developing bilateral dacryocystitis requiring bilateral dacryocystorhinostomies.

Introduction: The purpose of this study was to review the clinical utility of 2- [18F]-fluoro-2-deoxy-D-glucose positron emission tomography (FDG-PET) in the diagnostic evaluation of a series of patients with tumors of the nasopharynx, paranasal sinuses, and nasal cavity. Methods: The study group included 16 patients from a single institution who underwent a total of 31 FDG-PET scans for the evaluation of various histologic types of masses of the nasopharynx, nasal cavity, and paranasal sinuses for diagnosis and or surveillance. A review of the patients' medical records was performed in order to obtain all data including tumor type and location, PET scan results, CT and MRI results, treatments performed, tumor recurrence, and clinical outcome. This data was analyzed to determine the utility of FDGPET in the identification of primary tumors and/or recurrent disease. Results: FDG-PET identified 100% of all primary tumors examined with initial diagnostic intent (n=8). In addition, 1 case of lymphoid hyperplasia was correctly identified as nonmalignant. Of 22 PET scans performed for tumor surveillance, 16 scans identified recurrent disease and 5 scans were correctly interpreted as negative. One scan showed an area of increased metabolism at the base of tongue suspicious for malignancy that later proved to be an inflammatory process (1 false positive). Conclusion: FDG-PET was an effective imaging modality in the evaluation of primary and recurrent tumors of the nasopharynx, paranasal sinuses, and nasal cavities in our series. As a functional scanning modality, FDG-PET is particularly useful in tumor surveillance where normal anatomy has been disrupted by prior surgery or radiation. Our series reaffirms the results of similar series with respect to the use of PET in these particular sub sites of the head and neck. [ABSTRACT FROM AUTHOR]

Objective: Amiodarone can cause thyroid dysfunction in patients with or without previous thyroid disease. With increased use from its placement in advanced cardiac life support guidelines and cardiac transplant programs, the incidence of amiodarone-induced thyrotoxicosis (AIT) will likely increase. Medical management is complex and nonuniform and frequently fails. This study investigates the role of surgery in AIT and proposes indications for surgical management.Study Design and Setting: Two AIT case reports at a tertiary care institution and 31 surgical AIT cases in the world literature are reviewed.Methods: The 2 AIT cases involved patients with cardiomyopathy and resistant arrhythmias. Despite medical therapy, both patients' conditions failed to improve. Thirty-one surgical cases of AIT in the literature are evaluated with respect to symptoms and onset, medical therapy, AIT classification, pathology, perioperative management, and complications.Results: Both patients underwent total thyroidectomy without difficulty or complication, one as an overnight stay and one as an inpatient with an intraaortic balloon pump. One patient received a successful cardiac transplant and the other remains a viable candidate. In the literature, the majority (80%) of surgical cases are AIT type II (less common type) with no underlying thyroid disease. Range and duration of symptoms varied, in addition to type and duration of medical management. Almost all patients underwent total thyroidectomy, and all were successful with no mortality and minimal morbidity.Conclusion: AIT can develop in any patient during or after amiodarone therapy. Medical management is extremely difficult due to the absence of a proven therapeutic armamentarium, and surgery offers a safe, viable option. Surgical management should play a larger role in treatment algorithms and should be strongly considered for patients whose conditions necessitate continuation of amiodarone, or with severe symptoms resistant to medical therapy.

Radio-guided surgery is an established means for surgeons to identify a target of interest for biopsy or excision. This technique is used for a variety of malignancies as well as minimally invasive parathyroid surgery. The primary radionuclide used for these procedures is technetium-99m (Tc-99m), but others have been used. Use of (18)fluorine-fluorodeoxyglucose ((18)F-FDG) in oncology has proliferated. This has created the opportunity to use (18)F-FDG as a potential radio tracer in the operating room. A pilot study of three patients with non-iodine avid thyroid cancers undergoing (18)F-FDG-guided revision thyroid cancer surgery is reported. Radiation exposure to operating room personnel was measured. Radiation exposure to the surgeon and staff members of an operating room is well below the limits of the National Regulatory Commission. Therefore, utilization of this radiopharmaceutical intraoperatively should not be limited in the future because of concern regarding exposure of operating room personnel to radiation.

18F-2-deoxyglucose positron emission tomography (PET) is a frequent diagnostic tool used to evaluate patients with head and neck squamous cell carcinoma (HNSCC). 18F-2-deoxyglucose-PET is used in this setting for detection of metastases (staging) and/or second primaries. False-positive PET scans (10%-15% frequency) can distract from accurate HNSCC staging and an orderly prescription for treatment. Teflon (DuPont, Wilmington, DE) vocal fold injections can result in granuloma formation that has been described to generate a false-positive uptake on PET. We present a case of an injected vocal cord that appeared as a second laryngeal primary in a patient with recurrent nasopharyngeal cancer. [ABSTRACT FROM AUTHOR]

Direct traumatic optic neuropathy is a rare complication of endoscopic sinus surgery and can result in irreversible damage to the optic nerve. We report a case of direct traumatic optic neuropathy after transnasal endoscopic orbital decompression for Graves's disease in a patient who experienced near-complete recovery of vision. We discuss possible mechanisms. [ABSTRACT FROM AUTHOR]

Background: Pre-operative imaging is a well-established practice for managing hyperparathyroidism with the plan for excision; however, there is a paucity of information regarding the success rate of concordant imaging studies. Our goal was to compare the accuracy (sensitivity) of four-dimensional computed tomography (4DCT) and ultrasound (US) when predicting the side and quadrant of parathyroid lesions, confirmed with surgical location (from a single surgeon)., Methods: A retrospective review of 437 patients from a single surgeon undergoing parathyroidectomy from December 2013 to January 2020 at an academic medical center was performed. Masses >5 mm in dimension in eutopic parathyroid locations were identified as possible parathyroid lesions on 4DCT. A unique codified system was utilized to accurately record imaging results for each modality and compared to surgical findings., Results: Four hundred and thirty-seven patients underwent parathyroid surgery, of those 431 underwent 4DCT, 413 underwent US, and 408 underwent both. 4DCT accurately lateralized lesions in 319 (74.0%; N=431). US lateralized lesions in 265 (64.2%; N=413). The sensitivity for lateralization was 81.2% and 69.9% for 4DCT and US, respectively., Conclusions: 4DCT and US identify the majority of parathyroid lesions. 4DCT outperformed US in lateralization yet both modalities remain useful and are complimentary in planning for successful parathyroidectomy. Newer imaging approaches such as 18 F-choline positron emission tomography/computed tomography (PET/CT) and artificial intelligence as an augmentation to imaging review may play in role to identify parathyroid adenomas/hyperplasia, but their roles have yet to be clearly defined., Competing Interests: Conflicts of Interest: All authors have completed the ICMJE uniform disclosure form (available at https://gs.amegroups.com/article/view/10.21037/gs-24-141/coif).

Background: This study examined the trajectory of health-related quality of life (HRQoL) for patients with clinical stage N0 HNSCC enrolled in ACRIN 6685 who underwent elective neck dissection(s)., Methods: HRQoL of 230 patients in the ACRIN 6685 trial was measured prospectively up to 2 years following surgery using the University of Washington Quality of Life instrument., Results: General Health Within the Last 7 Days did not differ significantly from baseline at any follow-up. General Health Relative to Before Cancer fell significantly by 5.8 points following surgery (p = 0.048), and then returned to 3.0 points above baseline at 1 year (p = 0.65). For Overall Quality of Life, HRQoL fell significantly by 4.3 points following surgery (p = 0.031) and then returned to levels not significantly different from baseline., Conclusions: Patients with stage N0 HNSCC experience significant declines in HRQoL immediately following surgery, including neck dissection, which recovers to near or better than baseline within 1-2 years., (© 2024 The Authors.

Importance: Oncocytic (Hürthle cell) thyroid carcinoma is a follicular cell-derived neoplasm that accounts for approximately 5% of all thyroid cancers. Until recently, it was categorized as a follicular thyroid carcinoma, and its management was standardized with that of other differentiated thyroid carcinomas. In 2022, given an improved understanding of the unique molecular profile and clinical behavior of oncocytic thyroid carcinoma, the World Health Organization reclassified oncocytic thyroid carcinoma as distinct from follicular thyroid carcinoma. The International Thyroid Oncology Group and the American Head and Neck Society then collaborated to review the existing evidence on oncocytic thyroid carcinoma, from diagnosis through clinical management and follow-up surveillance., Observations: Given that oncocytic thyroid carcinoma was previously classified as a subtype of follicular thyroid carcinoma, it was clinically studied in that context. However, due to its low prevalence and previous classification schema, there are few studies that have specifically evaluated oncocytic thyroid carcinoma. Recent data indicate that oncocytic thyroid carcinoma is a distinct class of malignant thyroid tumor with a group of distinct genetic alterations and clinicopathologic features. Oncocytic thyroid carcinoma displays higher rates of somatic gene variants and genomic chromosomal loss of heterozygosity than do other thyroid cancers, and it harbors unique mitochondrial DNA variations. Clinically, oncocytic thyroid carcinoma is more likely to have locoregional (lymph node) metastases than is follicular thyroid carcinoma-with which it was formerly classified-and it develops distant metastases more frequently than papillary thyroid carcinoma. In addition, oncocytic thyroid carcinoma rarely absorbs radioiodine., Conclusions and Relevance: The findings of this review suggest that the distinct clinical presentation of oncocytic thyroid carcinoma, including its metastatic behavior and its reduced avidity to radioiodine therapy, warrants a tailored disease management approach. The reclassification of oncocytic thyroid carcinoma by the World Health Organization is an important milestone toward developing a specific and comprehensive clinical management for oncocytic thyroid carcinoma that considers its distinct characteristics.

Postoperative hypoparathyroidism may cause significant patient morbidity and even mortality. Emerging technologies centered on autofluorescent properties of parathyroid glands when exposed to near-infrared light hold promise to improve surgical parathyroid gland identification and preservation. Two systems (probe-based and camera-based) are commercially available currently; however, neither system alone provides indication of vascular viability or postoperative parathyroid gland function. The administration of indocyanine green, when combined with near-infrared fluorescence imaging, enables subjective assessment of parathyroid gland perfusion. Additional technologies to assess parathyroid gland perfusion are being developed. The impact of these nascent technologies on relevant clinical outcomes is an area of active investigation., (Copyright © 2023 Elsevier Inc. All rights reserved.)

Secondary hyperparathyroidism (SHPT) does not initiate as a primary dysfunction of parathyroid glands resulting from an intrinsic defect or disease but is the physiologic response of parathyroids to metabolic changes elsewhere in the body occurring over time. SHPT is a manifestation of a chronic condition that classically occurs from chronic kidney disease. In fact, given the relatively recent transition of populations from outside (agrarian) to indoor (industrial, information technology, and so forth) employment and a consequent reduction in sun exposure, combined with diets of highly processed food, vitamin D and calcium deficiencies are now the leading causes of SHPT., (Copyright © 2023 Elsevier Inc.

Background: With recent efforts to decrease opioid use following surgery, this study aims to answer: what pain regimen do patients follow at home? Is it controlling pain?, Methods: This is a prospective, pilot study of thyroid and parathyroid surgery patients. Patients were prescribed acetaminophen, ibuprofen, and tramadol dispensed in smart pill (Pillsy) bottles that record "events" corresponding to medication use. Patients received messages querying their current pain level. Patients were compared to historical controls., Results: 26 patients were in the Pillsy group and 30 in the control group. In the Pillsy group, pain scores averaged 3.67 out of 10 in the first 24 h after surgery and decreased each day. Patients took an average of 6.45 doses of acetaminophen, 6.64 doses of ibuprofen, and 1.82 doses of tramadol in the first week., Conclusions: Pain scores are highest in the first 24 h after surgery and decrease thereafter. This acceptable level of pain can be achieved with non-opioid medications., Competing Interests: Declaration of competing interest An initial subset of these findings were presented at the Triological Society at COSM Virtual 2021.

Importance: Identification and preservation of parathyroid glands (PGs) remain challenging despite advances in surgical techniques. Considerable morbidity and even mortality result from hypoparathyroidism caused by devascularization or inadvertent removal of PGs. Emerging imaging technologies hold promise to improve identification and preservation of PGs during thyroid surgery., Observation: This narrative review (1) comprehensively reviews PG identification and vascular assessment using near-infrared autofluorescence (NIRAF)-both label free and in combination with indocyanine green-based on a comprehensive literature review and (2) offers a manual for possible implementation these emerging technologies in thyroid surgery., Conclusions and Relevance: Emerging technologies hold promise to improve PG identification and preservation during thyroidectomy. Future research should address variables affecting the degree of fluorescence in NIRAF, standardization of signal quantification, definitions and standardization of parameters of indocyanine green injection that correlate with postoperative PG function, the financial effect of these emerging technologies on near-term and longer-term costs, the adoption learning curve and effect on surgical training, and long-term outcomes of key quality metrics in adequately powered randomized clinical trials evaluating PG preservation.

Introduction: FDG PET/CT was prospectively studied in 287 cN0 head and neck cancer patients in ACRIN 6685, and additional analysis of neck FDG uptake upon recurrence-free survival (RFS) and overall survival (OS) was performed., Patients and Methods: Two hundred eight had analyzable data. Survival analysis was performed to compare RFS and OS based on neck FDG visual assessment (VA) and SUV max . For SUV max , the optimal thresholds were calculated using conditional inference trees on a randomly selected 70% training data set and validated using the remaining 30% of data. Kaplan-Meier curves with log-rank tests were generated for the patient groups based on VA and optimal SUV max thresholds, and the hazards ratios (HRs) and 95% confidence intervals (CIs) were also calculated. Hypothesis testing was set at a significance level of 0.05., Results: A total of 73.9% of bilateral cN0 and 50.0% of unilateral cN0 were alive at the end of the study with the remaining being dead or lost to follow-up. Overall survival median follow-up time was 24.0 months (interquartile range, 15.8-25.3; range, 0-37.0). A total of 63.3% of bilateral cN0 and 42.5% of unilateral cN0 patients remained disease free during the study. Recurrence-free survival median follow-up time was 23.9 months (interquartile range, 12.4-25.2; range, 0-35.6). Visual assessment of necks by our panel of radiologists was significantly associated with RFS (HR [95% CI], 2.30 [1.10-4.79]; P = 0.02), but not with OS (HR [95% CI], 1.64 [0.86-3.14]; P = 0.13). The optimal SUV max thresholds were 2.5 for RFS and 5.0 for OS. For SUV max assessment, applying the optimal thresholds to the 30% test data yielded HRs (95% CIs) of 2.09 (0.61-7.14; P = 0.23) for RFS and 3.42 (1.03-11.41; P = 0.03) for OS. The SUV max threshold of 5.0 was significantly associated with RFS (HR [95% CI], 5.92 [1.79-19.57]; P < 0.001)., Conclusions: Neck FDG uptake by VA is significant for RFS. An SUV max threshold of 5.0 is significantly associated with OS and RFS., Competing Interests: Conflicts of interest and sources of funding: The authors declare that they have no conflicts of interest.

Importance: Counseling prior to thyroid cancer (TC) treatment is an essential component of informed consent. An informed patient affects treatment-related expectations and patient engagement, factors that contribute significantly to patient-reported quality-of-life outcomes., Objective: To describe experiences with pretreatment counseling among survivors of TC and to test factors associated with self-reported treatment meeting expectations., Design, Setting, and Participants: A cross-sectional survey was administered between October 18, 2019, and February 8, 2020, to members of ThyCa: Thyroid Cancer Survivors' Association Inc, and to individuals accessing the public-facing ThyCa website. Survey respondents were asked 55 questions, including 4 free-text questions and 2 multiple-choice questions about pretreatment counseling., Main Outcomes and Measures: Respondents self-reported (1) their unmet information needs, (2) rates of treatment meeting expectations, and (3) rates of treatment understanding. A mixed-methods analysis was performed, including qualitative content analysis of free-text responses and multivariable logistic regression of factors associated with self-reported levels of treatment meeting expectations., Results: Of the 1412 survey respondents, 1249 were women (88.4%). The median age at diagnosis was 48 years (range, 18-85 years), and the median age at the time of survey completion was 60 years (range, 18-87 years). A total of 1259 respondents (89.2%) provided free-text responses to the question, "What would you tell someone newly diagnosed with your same condition?" Of these individuals, 526 (37.2%) reported inadequate pretreatment plan understanding and 578 (40.9%) reported that their treatment experience did not meet their expectations. Treatment met expectations for only 95 respondents (18.1%) reporting an inadequate pretreatment plan understanding. Of the 526 survivors of TC reporting a lack of understanding, 473 (90.0%) provided additional textual comments, most commonly in the categories of postoperative treatment, surveillance, and treatment effects. On multivariable logistic regression, self-reported failure to have an understanding of TC treatment was independently associated with failure of treatment to meet expectations (odds ratio, 5.1 [95% CI, 3.7-6.9]). Patients reporting a full understanding of their treatment plan were 5-fold more likely to indicate that their initial treatment experience was on par with expectations, independent of reported postoperative complications, age, sex, and other potential confounders., Conclusions and Relevance: In this survey study, a substantial proportion of survivors of TC reported inadequate pretreatment understanding. This gap in understanding was associated with high levels of self-reported failure of treatment to meet expectations, which in turn is associated in other studies with poorer patient-reported quality-of-life outcomes. These outcomes may be improved by addressing gaps in patient understanding so expectations more closely match TC diagnosis and treatment pathways.

To our knowledge, no prior multicenter clinical trial has reported interobserver agreement of 18 F-FDG PET/CT scans for staging of clinical N0 neck in head and neck cancer. Methods: A total of 287 participants were recruited. For visual analysis, positive nodal uptake of 18 F-FDG was defined as uptake visually greater than activity seen in the blood pool. Results: The negative predictive value of the 18 F-FDG PET/CT for N0 clinical neck was 86% or above for visual assessment (95% CI, 86%-88%) for the 2 central readers and above 90% (95% CI, 90%-95%) for SUV max for central reads and site reads dichotomized at the optimal cutoff value of 1.8 and the prespecified cutoff value of 3.5, respectively. The κ coefficients between the 2 expert readers and between central reads and site reads varied between 0.53 and 0.78. Conclusion: The NPV of the 18 F-FDG PET/CT for N0 clinical neck was 86% or above for visual assessment and above 90% for SUV max cut points of 1.8 and 3.5 with moderate to substantial agreements., (© 2022 by the Society of Nuclear Medicine and Molecular Imaging.)

Importance: There is epidemiologic evidence that the increasing incidence of thyroid cancer is associated with subclinical disease detection. Evidence for a true increase in thyroid cancer incidence has also been identified. However, a true increase in disease would likely be heralded by an increased incidence of thyroid-referable symptoms in patients presenting with disease., Objectives: To evaluate whether modes of detection (MODs) used to identify thyroid nodules for surgical removal have changed compared with historic data and to determine if MODs vary by geographic location., Design, Setting, and Participants: This was a retrospective analysis of pathology and medical records of 1328 patients who underwent thyroid-directed surgery in 16 centers in 4 countries: 4 centers in Canada, 1 in Denmark, 1 in South Africa, and 12 in the US. The participants were the first 100 patients (or the largest number available) at each center who had thyroid surgery in 2019. The MOD of the thyroid finding that required surgery was classified using an updated version of a previously validated tool as endocrine condition, symptomatic thyroid, surveillance, or without thyroid-referable symptoms (asymptomatic). If asymptomatic, the MOD was further classified as clinician screening examination, patient-requested screening, radiologic serendipity, or diagnostic cascade., Main Outcomes and Measures: The MOD of thyroid nodules that were surgically removed, by geographic variation; and the proportion and size of thyroid cancers discovered in patients without thyroid-referable symptoms compared with symptomatic detection. Data analyses were performed from April 2021 to February 2022., Results: Of the 1328 patients (mean [SD] age, 52 [15] years; 993 [75%] women; race/ethnicity data were not collected) who underwent thyroid surgery that met inclusion criteria, 34% (448) of the surgeries were for patients with thyroid-related symptoms, 41% (542) for thyroid findings discovered without thyroid-referable symptoms, 14% (184) for endocrine conditions, and 12% (154) for nodules with original MOD unknown (under surveillance). Cancer was detected in 613 (46%) patients; of these, 30% (183 patients) were symptomatic and 51% (310 patients) had no thyroid-referable symptoms. The mean (SD) size of the cancers identified in the symptomatic group was 3.2 (2.1) cm (median [range] cm, 2.6 [0.2-10.5]; 95% CI, 2.91-3.52) and in the asymptomatic group, 2.1 (1.4) cm (median [range] cm, 1.7 [0.05-8.8]; 95% CI, 1.92-2.23). The MOD patterns were significantly different among all participating countries., Conclusions and Relevance: This retrospective analysis found that most thyroid cancers were discovered in patients who had no thyroid-referable symptoms; on average, these cancers were smaller than symptomatic thyroid cancers. Still, some asymptomatic cancers were large, consistent with historic data. The substantial difference in MOD patterns among the 4 countries suggests extensive variations in practice.

Background: The development of systemic treatment options leveraging the molecular landscape of advanced thyroid cancer is a burgeoning field. This is a multidisciplinary evidence-based statement on the definition of advanced thyroid cancer and its targeted systemic treatment., Methods: An expert panel was assembled, a literature review was conducted, and best practice statements were developed. The modified Delphi method was applied to assess the degree of consensus for the statements developed by the author panel., Results: A review of the current understanding of thyroid oncogenesis at a molecular level is presented and characteristics of advanced thyroid cancer are defined. Twenty statements in topics including the multidisciplinary management, molecular evaluation, and targeted systemic treatment of advanced thyroid cancer are provided., Conclusions: With the growth in targeted treatment options for thyroid cancer, a consensus definition of advanced disease and statements regarding the utility of molecular testing and available targeted systemic therapy is warranted., (© 2022 Wiley Periodicals LLC.)

Children are more likely to experience recurrent laryngeal nerve (RLN) injury during thyroid surgery. Intraoperative nerve monitoring (IONM) may assist in nerve identification and surgical decision making. A literature review of pediatric IONM was performed and used to inform a monitoring technique guide and expert opinion statements. Pediatric IONM is achieved using a variety of methods. When age-appropriate endotracheal tubes with integrated surface electrodes are not available, an alternative method should be used. Patient age and surgeon experience with laryngoscopy influence technique selection; four techniques are described in detail. Surgeons must be familiar with the nuances of monitoring technique and interpretation; opinion statements address optimizing this technology in children. Adult IONM guidelines may offer strategies for surgical decision making in children. In some cases, delay of second-sided surgery may reduce bilateral RLN injury risk., (© 2022 Wiley Periodicals LLC.)

Background: To prove the concept of diagnosing primary hyperparathyroidism (pHPT) without calcium and parathyroid hormone (PTH) values and identifying potential risk factors for pHPT., Methods: Data were extracted from the clinical data warehouse (CDW) at the University of Arkansas for Medical Sciences (UAMS) Epic EHR (2014-2019)., Results: 1737 patients with over 185 000 rows of clinical data were provided in a relational structure and processed/flattened to facilitate modeling. Phenotype elements were identified for pHPT without advance knowledge of calcium and PTH levels. The area under the curve (AUC) for the prediction of pHPT using our model was 0.86 with sensitivity and specificity of 0.8953 and 0.6686, respectively, using a 0.45 probability threshold., Conclusion: Primary hyperparathyroidism was predicted from a dataset excluding calcium and PTH data with 86% accuracy. This approach needs to be validated/refined on larger samples of data and plans are in place to do this with other regional/national datasets., (© 2021 Wiley Periodicals LLC.)

Background: The use of ultrasound-guided ablation procedures to treat both benign and malignant thyroid conditions is gaining increasing interest. This document has been developed as an international interdisciplinary evidence-based statement with a primary focus on radiofrequency ablation and is intended to serve as a manual for best practice application of ablation technologies., Methods: A comprehensive literature review was conducted to guide statement development and generation of best practice recommendations. Modified Delphi method was applied to assess whether statements met consensus among the entire author panel., Results: A review of the current state of ultrasound-guided ablation procedures for the treatment of benign and malignant thyroid conditions is presented. Eighteen best practice recommendations in topic areas of preprocedural evaluation, technique, postprocedural management, efficacy, potential complications, and implementation are provided., Conclusions: As ultrasound-guided ablation procedures are increasingly utilized in benign and malignant thyroid disease, evidence-based and thoughtful application of best practices is warranted., (© 2021 Wiley Periodicals LLC.)

Importance: Increasing detection of early-stage papillary thyroid neoplasms without improvements in mortality has prompted development of strategies to prevent or mitigate overtreatment., Objective: To determine adoption rates of 2 recent strategies developed to limit overtreatment of low-risk thyroid cancers: (1) a new classification, noninvasive follicular thyroid neoplasm with papillarylike nuclear features (NIFTP), and (2) hemithyroidectomy for selected papillary thyroid carcinomas (PTCs) up to 4 cm in size., Design, Setting, and Participants: This is a cross-sectional analysis of 3368 pathology records of 2 cohorts of patients from 18 hospitals in 6 countries during 2 time periods (2015 and 2019). Participating hospitals were included from the US (n = 12), Canada (n = 2), Denmark (n = 1), South Korea (n = 1), South Africa (n = 1), and India (n = 1). The records of the first 100 patients per institution for each year who underwent thyroid-directed surgery (hemithyroidectomy, total thyroidectomy, or completion thyroidectomy) were reviewed., Main Outcomes and Measures: Frequency of diagnosis of NIFTP, PTCs, and thyroidectomies during the study period., Results: Of the 790 papillary thyroid neoplasms captured in the 2019 cohort, 38 (4.8%) were diagnosed as NIFTP. Diagnosis of NIFTP was observed in the US, South Africa, and India. There was minimal difference in the total proportion of PTCs in the 2015 cohort compared with the 2019 cohort (778 [47.1%] vs 752 [44.5%]; difference, 2.6% [95% CI, -16.9% to 22.1%]). The proportion of PTCs eligible for hemithyroidectomy but treated with total thyroidectomy in the 2 cohorts demonstrated a decreasing trend from 2015 to 2019 (341 of 453 [75.3%] vs 253 of 434 [58.3%]; difference, 17.0% [95% CI, -1.2% to 35.2%])., Conclusions and Relevance: Results of this cohort study showed that the 2 mitigation strategies for preventing overtreatment of early-stage thyroid cancer have had mixed success. The diagnosis of NIFTP has only been applied to a small proportion of thyroid neoplasms compared with expected rates. However, more patients eligible for hemithyroidectomy received it in 2019 compared with 2015, showing some success with this deescalation strategy.

Background: Intraoperative neuromonitoring (IONM) techniques have evolved over the past decade into intermittent IONM (I-IONM) and continuous IONM (C-IONM) modes of application. Despite many prior publications on both types of IONM, there remains uncertainty about what outcomes should be measured for each form of IONM. The primary objective of this paper is to define categories of benefit for I-IONM/C-IONM and to clarify and standardize their reporting outcomes., Methods: Expert review consensus statement utilizing modified Delphi methodology., Results: I-IONM provides diagnosis, classification, and prevention of nerve injury through accurate and early nerve identification. C-IONM provides real-time information on nerve functional integrity and thus may prevent some types of nerve injury but cannot assist in nerve localization. Sudden mechanisms of nerve injury cannot be predicted or prevented by either technique., Conclusions: I-IONM and C-IONM are complementary techniques. Future studies evaluating the utility of IONM should focus on outcomes that are appropriate to the type of IONM being utilized., (© 2021 Wiley Periodicals LLC.)

Objective: Assess the impact of surgical technique used to address level IV on the rate of postoperative chyle leak., Study Design: Retrospective chart review., Setting: Academic tertiary care center., Methods: An analysis of 436 consecutive neck dissections (NDs) in 368 patients was performed by 3 head and neck surgeons between 2014 and 2017. Variation in technique reflects individual approaches to the management of level IV and included suture ligation (SL), monopolar electrocautery (MC), and harmonic scalpel transection (HS). Data points included patient demographics, surgical technique, intraoperative findings, postoperative chyle leaks, and leak management. Correlation between variables was analyzed through χ 2 test and Student t test with statistical α set at .05., Results: Overall, 12 patients (3.2%) developed chyle leaks postoperatively. Nine of 12 and 3 of 12 presented with left- and right-sided leaks, respectively. Five of 12 leaks occurred following bilateral ND, 5 of 12 following left ND, and 2 of 12 following right ND. Univariate analysis showed a statistically significant difference ( P = .001) favoring SL (1.0%) and MC (1.2%) techniques over the HS technique (8.6%). A statistically significant increase existed in the rate of leak with endocrine vs nonendocrine pathology ( P = .003). Average duration of leak was 13.3 ± 13.5 days. Management included diet modification (n = 11, 91.6%), pressure-dressing placement (n = 7, 58.3%), and octreotide (n = 5, 41.7%). No cases required reoperation, and no mortality or severe malnutrition was observed in this series., Conclusions: SL and MC techniques demonstrated superiority over the HS technique in preventative management of chyle leak in level IV, with a significantly higher rate of chyle leak observed in endocrine-related pathology.

Background: Intraoperative scintigraphy (IoS) has been proposed as a tool for real-time intraoperative decision-making regarding parathyroid adenoma localization and confirmation of excision., Methods: Retrospective review of patients who underwent minimally invasive parathyroidectomies with scintigraphy performed intraoperatively. Preoperative neck ultrasound, 4D computed tomography, as well as intraoperative parathyroid hormone (IOPTH) and gamma probe measurements were conducted per standard practice. IoS images were obtained prior to and following parathyroid excision. Cases were reviewed to determine accuracy of IoS for localizing parathyroid pathology and confirming successful excision., Results: Fifty-six cases met the inclusion criteria. Twenty-nine patients (51.8%) showed confirmation of excision of an abnormal gland on post-excision IoS. There were no significant differences in IOPTH reduction and postoperative laboratory values between patients with IoS-identified resolution and those without IoS-identified resolution., Conclusions: With low accuracy in correctly localizing abnormal glands and confirming their excision, there is no appreciable benefit of IoS at this time., (© 2021 Wiley Periodicals LLC.)

Objective: Variants of primary hyperparathyroidism (pHPT), described as normocalcemic (NC) and normohormonal (NH), can confuse the diagnosis of classic pHPT., Data Sources: A MEDLINE search was performed for variants of pHPT using the PubMed database (last queried October 2019)., Review Methods: The search was restricted to articles published after 1960 that were specific to humans. Studies were included in our analysis if laboratory values and incidence of end-organ involvement were reported for NCpHPT and NHpHPT variants. The search returned 189 articles; 27 additional studies were identified and included for a total of 216. Non-English-language studies were excluded. Abstracts were screened, full-text articles were then assessed, and 82 articles were excluded. Data were pooled using a random-effects model in studies that compared NC or NH pHPT to classic pHPT. Comparative laboratory values are presented., Conclusion: This analysis compares NCpHPT and NHpHPT to classic pHPT. Nephrolithiasis was 21.7% (NCpHPT), 15.9% (classic pHPT), and 25.4% (NHpHPT). Decreased bone mineral density was 49.7% (NCpHPT), 39.7% (classic pHPT), and 40.3% (NHpHPT). Fractures in the NCpHPT group were not significantly different from the classic pHPT. Hypertension in the NCpHPT group was significantly less than classic pHPT (odds ratio, 0.59; 95% CI, 0.40-0.88)., Implications for Clinical Practice: This information may serve to inform clinicians of the laboratory subtleties of these variants that are being seen with greater frequency in contemporary practice.

Background: This American Head and Neck Society (AHNS) consensus statement focuses on evidence-based comprehensive pain management practices for thyroid and parathyroid surgery. Overutilization of opioids for postoperative pain management is a major contributing factor to the opioid addiction epidemic however evidence-based guidelines for pain management after routine head and neck endocrine procedures are lacking., Methods: An expert panel was convened from the membership of the AHNS, its Endocrine Surgical Section, and ThyCa. An extensive literature review was performed, and recommendations addressing several pain management subtopics were constructed based on best available evidence. A modified Delphi survey was then utilized to evaluate group consensus of these statements., Conclusions: This expert consensus provides evidence-based recommendations for effective postoperative pain management following head and neck endocrine procedures with a focus on limiting unnecessary use of opioid analgesics., (© 2021 Wiley Periodicals LLC.)

Objective: FDG-PET/CT (fluorodeoxyglucose-positron emission tomography/computed tomography) is effective to assess for occult neck nodal disease. We report risks and patterns of nodal disease based on primary site and nodal level from data on the dissected cN0 per the results from ACRIN 6685., Study Design: Prospective nonrandomized enrollment included participants with first-time head and neck squamous cell carcinoma and at least 1 cN0 neck side to be dissected., Setting: Twenty-four ACRIN-certified centers internationally (American College of Radiology Imaging Network)., Methods: A total of 287 participants were enrolled. Preoperative FDG-PET/CT findings were centrally reviewed and compared with pathology. Incidence, relative risk, pattern of lymph node involvement, and impact upon neck dissection were reported., Results: An overall 983 nodal levels were dissected (n = 261 necks, n = 203 participants). The highest percentages of ipsilateral positive nodes by primary location and nodal level were oral cavity (level I, 17/110, 15.5%), pharynx (level II, 6/30, 20.0%), and larynx (level VI, 1/3, 33.3%)., Conclusion: Levels at greatest risk for nodal disease in cN0 in terms of ipsilateral neck dissection are level I (oral cavity), II (pharynx), and VI (larynx). These data should be considered when treating patients presenting with cN0. This is the first study to comprehensively report the incidence, location, and risk of metastases in cN0 in the FDG-PET/CT era.

Objective: Report outcomes of rapid implementation of telehealth across an academic otolaryngology-head and neck surgery department during the COVID-19 pandemic., Methods: This is a retrospective, single-institution study of rapid deployment of telehealth during the COVID-19 pandemic. Characteristics of patients were compared between those who agreed and those who declined telehealth care. Reasons for declining telehealth visits were ascertained. Characteristics of telehealth visits were collected and patients were asked to complete a post-visit satisfaction survey., Results: There was a 68% acceptance rate for telehealth visits. In multivariable analysis, patients were more likely to accept telehealth if they were being seen in the facial plastics subspecialty clinic (odds ratio [OR] 59.55, 95% confidence interval [CI] 2.21-1607.52; P = .015) compared to the general otolaryngology clinic. Patients with Medicare (compared to commercial insurance) as their primary insurance were less likely to accept telehealth visits (OR 0.10, 95% CI 0.01-0.77; P = .027). Two hundred and thirty one patients underwent telehealth visits; most visits (69%) were for established patients and residents were involved in 38% of visits. There was an 85% response rate to the post-visit survey. On a scale of one to ten, the median satisfaction score was 10 and 99% of patients gave a score of 8 or higher. Satisfaction scores were higher for new patient visits than established patient visits ( P = .020)., Conclusion: Rapid implementation of telehealth in an academic otolaryngology-head and neck surgery department is feasible. There was high acceptance of and satisfaction scores with telehealth., Level of Evidence: 3., Competing Interests: The authors declare no conflicts of interest., (© 2021 The Authors.

Objective: To develop and assess an otolaryngology-specific surgical priority scoring system that incorporates varying levels of mucosal involvement., Study Design: Retrospective cohort., Setting: Academic medical center., Methods: A novel mucosal score was developed based on best available evidence. This mucosal score was incorporated into the Medically Necessary, Time-Sensitive (MeNTS) score to generate a MeNTS-Mucosal (MeNTS-M) score. A retrospective cohort of patients was identified to assess the surgical priority scoring systems. Inclusion criteria included all scheduled surgical procedures between March 23, 2020, and April 17, 2020. Decisions about whether to proceed or cancel were made based on best clinical judgment by surgeons, without use of any surgical priority scores. The predictive value of the surgical priority scoring systems was assessed in this retrospective cohort., Results: The median MeNTS score was significantly lower in adult patients whose surgery proceeded compared to those for whom the surgery was cancelled (48 vs 56; P = .004). Mucosal and MeNTS-M scores were not statistically different based on whether surgery proceeded. Among adult patients, the highest area under the curve (AUC) was for the MeNTS scoring system (0.794); both the mucosal and MeNTS-M systems had lower AUC values (which were significantly lower than the AUC for the MeNTS scoring system)., Conclusion: This study represents development and assessment of the first otolaryngology-specific surgical priority score and incorporates varying levels of mucosal disruption. The combined MeNTS-M scoring system could be a valuable tool in appropriately triaging otolaryngology-head and neck surgery procedures., (© The Authors 2021.)

Background: Opioid abuse is widespread in the United States and the risk for chronic use is increased in surgical patients, including patients with thyroid and parathyroid., Methods: Records for 171 patients prior to and 67 patients following implementation of an enhanced recovery after surgery (ERAS) protocol for ambulatory thyroid/parathyroid surgeries were reviewed. The ERAS included superficial cervical plexus block, multimodal premedication, and postoperative reliance on acetaminophen and ibuprofen with judicious prescribing of opioids., Results: Post-ERAS patients were prescribed a mean 72 morphine milligram equivalents (MME); pre-ERAS patients were prescribed a mean 163 MME (p < 0.001). 97.1% of pre-ERAS patients were prescribed opioids with 91.1% filled; 68.7% of post-ERAS study patients were prescribed opioids with 84.8% filled., Conclusion: Implementation of ERAS and focus on prescribing practices decreased the MME prescribed and used for ambulatory thyroid and parathyroid surgery. Future steps include increased patient education and tracking pain scores and medication utilization out of hospital., (© 2021 Wiley Periodicals LLC.)

Objectives: To provide a clinical disease state review of recent relevant literature and to generate expert consensus statements regarding the breadth of pediatric thyroid cancer diagnosis and care, with an emphasis on thyroid surgery. To generate expert statements to educate pediatric practitioners on the state-of-the-art practices and the value of surgical experience in the management of this unusual and challenging disease in children., Methods: A literature search was conducted and statements were constructed and subjected to a modified Delphi process to measure the consensus of the expert author panel. The wording of statements, voting tabulation, and statistical analysis were overseen by a Delphi expert (J.J.S.)., Results: Twenty-five consensus statements were created and subjected to a modified Delphi analysis to measure the strength of consensus of the expert author panel. All statements reached a level of consensus, and the majority of statements reached the highest level of consensus., Conclusion: Pediatric thyroid cancer has many unique nuances, such as bulky cervical adenopathy on presentation, an increased incidence of diffuse sclerosing variant, and a longer potential lifespan to endure potential complications from treatment. Complications can be a burden to parents and patients alike. We suggest that optimal outcomes and decreased morbidity will come from the use of advanced imaging, diagnostic testing, and neural monitoring of patients treated at high-volume centers by high-volume surgeons., (© AACE published by Elsevier Inc. as a dual publication under license from Wiley Periodicals, LLC.)

Objective: To determine the significance and impact of additional chloride testing as part of a diagnostic laboratory test battery for borderline primary hyperparathyroidism (pHPT)., Study Design: Retrospective database review of parathyroidectomy patients., Setting: A tertiary care, academic health sciences center., Subjects and Methods: Patients referred to a head and neck endocrine clinic for evaluation and treatment for pHPT., Results: After exclusions, there were a total of 226 patients who underwent parathyroidectomy for primary hyperparathyroidism with the requisite preoperative and postoperative labs. Seventy-seven additional patients who had a thyroid operation for a nonmalignant cause were included as controls. Of the 303 total patients, 166 had normal calcium levels (<10.4 mg/dL), and 54 (32.5%) also exhibited hyperchloremia (>106 mmol/L). Of the 47 patients with normal calcium and parathyroid hormone (PTH) levels (<88 pg/mL), 6 (12.8%) had hyperchloremia, and of the 118 patients with normocalcemic pHPT, 48 (40.7%) were hyperchloremic. The area under the curve for the Cl:PO4 was 0.712. When using a cutoff of 33, the reported sensitivity and specificity of the curve were 58.4% and 28.6%, respectively., Conclusion: The Cl:PO4 ratio was a moderately sensitive test for the diagnosis of the borderline variants of primary hyperparathyroidism. The Ca:PO4 ratio was superior to the Cl:PO4 ratio. Our data also showed the superiority of preoperative calcium and ionized calcium over PTH when predicting the presence of pHPT.

Background: Laryngeal dysfunction after thyroid and parathyroid surgery requires early recognition and a standardized approach for patients that present with voice, swallowing, and breathing issues. The Endocrine Committee of the American Head and Neck Society (AHNS) convened a panel to define the terms "immediate vocal fold paralysis" and "partial neural dysfunction" and to provide clinical consensus statements based on review of the literature, integrated with expert opinion of the group., Methods: A multidisciplinary expert panel constructed the manuscript and recommendations for laryngeal dysfunction after thyroid and parathyroid surgery. A meta-analysis was performed using the literature and published guidelines. Consensus was achieved using polling and a modified Delphi approach., Results: Twenty-two panelists achieved consensus on five statements regarding the role of early identification and standardization of evaluation for patients with "immediate vocal fold paralysis" and "partial neural dysfunction" after thyroid and parathyroid surgery., Conclusion: After endorsement by the AHNS Endocrine Section and Quality of Care Committee, it received final approval from the AHNS Council., (© 2020 Wiley Periodicals LLC.)

Background: Self-awareness of skill, essential for progression as a surgeon, has direct bearing on postresidency practice; however, studies have supported that residents achieve self-perceived competence later than believed by program directors. This study compares residents' self-perception of operative competency to attending surgeon's evaluation using Computer Enhanced Visual Learning, a validated online hemithyroidectomy-specific assessment tool., Methods: Eleven otolaryngology-Head and Neck Surgery (HNS) residents completed a preoperative module and postoperative survey, later reviewed by an attending surgeon. Eighty-three performances were assessed for inter-rater reliabilities of key surgical steps., Results: Almost perfect agreement (Kappa = 0.81-1.00) was shown in 11 of 18 parameters. Substantial agreement (Kappa = 0.61-0.80) was demonstrated in the remaining seven parameters., Conclusions: Otolaryngology-HNS trainees have high self-awareness of their performance at each step in a hemithyroidectomy. Standardized assessment tools can allow for documentation of procedural performance and serve as guides for improvement. This is the only study to examine otolaryngology-HNS trainees' self-perceived skill compared to an attending surgeon's assessment for hemithyroidectomy., (© 2020 Wiley Periodicals LLC.)

Introduction: Primary hyperparathyroidism (PHPT) is a condition in which one or more parathyroid glands secrete excess amounts of parathyroid hormone (PTH). In short, PHPT is characterized by hypercalcemia/hypercalciuria with concurrent elevated PTH levels. This condition is known to increase the risk of cardiovascular disease, osteoporosis, psychiatric disturbances, and renal complications. As of now, the disease typically runs a long course before being identified and treated. At present, surgery is the only viable treatment option for patients with this disease. Publications from other tertiary centers have identified a large-scale underdiagnosis of PHPT. The aim of this study is to determine if similar trends exist at the University of Arkansas for Medical Sciences (UAMS). Moreover, this study was seen as a first step to developing a machine learning strategy to diagnose PHPT in large clinical data sets., Methods: To evaluate for potential underdiagnosis of PHPT at UAMS, all patients from 2006 to 2018 with hypercalcemia and/or hypercalciuria (excluding those with known malignancies or other possible causes of excess serum calcium) were identified in electronic medical records. Then, it was evaluated whether these hypercalcemic/hypercalciuric patients received subsequent measurement of PTH levels necessary to confirm the diagnosis of HPT., Results: At UAMS between 2006 and 2018, 28 831 patients were identified as having hypercalcemia and/or hypercalciuria. Of these patients, only 7984 ever had subsequent PTH levels tested. Therefore, 20 847 (72.3%) of these patients never had PTH labs drawn., Conclusions: These findings may represent a significant patient population in which PHPT remains undiagnosed due to lack of follow-up. PHPT is often a silent disease with an insidious onset. At the point of diagnosis, typically the treatment is surgical removal of the offending parathyroid gland(s) (parathyroidectomy). Identification of underdiagnosis is the first step for subsequent improvement in the diagnosis of PHPT. Detection of this disease in its earlier stages may open the door for medical and lifestyle interventions, thereby decreasing long-term sequelae of the disease, such as osteoporosis, myocardial infarction, or stroke., Competing Interests: The authors declare that there is no conflict of interest or specific funding contributing to the publication of this article., (© 2020 The Authors.
