Thyroid hormone, produced in the thyroid gland, regulates metabolism, development, and cardiac function. The thyroid is susceptible to autoimmune attack by both cellular and humoral immunity exemplified by Hashimoto's thyroiditis (HT) and Graves' Disease (GD), respectively. In HT, immune-mediated destruction impairs thyroid hormone production, while in GD, stimulating autoantibodies promote over-production. Here, we generated a multi-modal atlas of 604,076 human thyroid and blood cells from HT, GD, and control patients. We found that, despite markedly different clinical presentations and distinct antigenic triggers, HT and GD exhibit convergent cellular dynamics resulting in a shared continuum of immune infiltration. Along this continuum, a key feature is a thyrocyte niche containing CD8 + T cells that may segregate pathogenic T cells from regions with preserved thyroid hormone production. These findings of a shared disease continuum characterized by spatially defined immune niches provide a new framework for understanding tissue homeostasis in human autoimmune disease.

Background Peripheral vascular interventions (PVIs) performed under procedural sedation and analgesia (PSA) can be associated with anxiety and poor compliance with patient instructions during surgery. Mind-body interventions (MBIs) such as meditation have demonstrated the potential to decrease perioperative anxiety, though this area is understudied, and no tailored interventions have been developed for the vascular surgical patient population. Objectives We aimed to design a perioperative MBI that specifically targeted vascular surgical patients undergoing PVIs under PSA. We sought to perform this in a scientifically rigorous, multi-disciplinary collaborative manner. Methods Following the Obesity-Related Behavioral Intervention Trials (ORBIT) model, we designed (Phase 1a) and then refined (Phase 1b) a MBI for patients undergoing PVIs under PSA to decrease perioperative anxiety and sedation and facilitate patient intraoperative compliance. Phase 1a involved a literature review, informal information gathering and synthesis, and drafting a preliminary protocol for a perioperative MBI. Phase 1b involved assembling a multi-disciplinary expert panel of perioperative and mind-body clinicians and researchers to improve the MBI using an iterative, modified Delphi approach. Results The modified Delphi process was completed, and a consensus was reached after three iterations. The resulting MBI consisted of two seven-minute preoperative guided meditations on the day of surgery, including diaphragmatic breathing, body scans, and guided imagery emphasizing awareness of the ipsilateral leg where the vascular surgery was performed. A document delineating the integration of the MBI into the operating room workflow was produced, including details regarding the intervention’s timing, duration, and modality. Conclusion Using a multi-specialty expert panel, we designed a novel MBI in the form of a guided meditation with elements of mindfulness and guided imagery to decrease anxiety and increase intraoperative compliance for patients undergoing PVIs under PSA. A prospective pilot study is being planned to test the program’s feasibility.

Surgeons have been under great pressure during the COVID pandemic. Their careers are filled with fast paced decisions, life and death situations, and long hours at work. The COVID pandemic created more tasks and even new responsibilities at times, but when the operating rooms were closed down, there was less work. The COVID experience invited the opportunity to rethink mentoring in the surgery department at the Massachusetts General Hospital. The leadership experimented with a new style of mentoring which involved a team approach. In addition, they tried something else that was new: adding a lifestyle medicine expert and wellness coach to the mentoring team. The program was tested on 13 early stage surgeons who found the experience to be beneficial, and they commented that they wished they had it even earlier in their careers. Including a non-surgeon who was a lifestyle medicine physician and wellness coach added an element of whole person health that was acceptable to the surgeons and even embraced as the majority of them elected to follow up with one on one coaching after the mentoring meeting. This team mentoring program with senior surgeons and a lifestyle medicine expert is one that can be explored by other departments and other hospitals given its success at the department of surgery at Massachusetts General Hospital.

BACKGROUND:Four-dimensional computed tomography (4D-CT) scan to localize abnormal parathyroid glands is diagnostically superior to ultrasound (US) and sestamibi. The implementation of 4D-CT imaging is unknown.METHODS:The Collaborative Endocrine Surgery Quality Improvement Program (CESQIP) database from 2014 to 2018 was utilized. Patients with hyperparathyroidism undergoing an initial operation were included. The rate of US, sestamibi and 4D-CT performance was calculated for the entire study population, and for each institution.RESULTS:7,959 patients were included. In 311(3.9%) patients, no preoperative imaging was recorded. Of patients with imaging, US was performed in 6,872(86.3%), sestamibi in 5,094(64.0%), and 4D-CT in 1,630(20.4%). The combination of US and sestamibi was most frequent (3,855, 48.4%). Institutional rates of 4D-CT performance varied from 0.1% to 88.7%.CONCLUSIONS:Of the imaging modalities, 4D-CT was utilized least frequently and with greatest variability. Given the high accuracy of 4D-CT, efforts to reduce this variation may improve overall preoperative localization in patients with hyperparathyroidism.

Primary hyperparathyroidism (PHPT) is the most common cause of hypercalcemia and can result in bone density loss and kidney stones. Increasingly more patients are being diagnosed in an asymptomatic phase of the disease because calcium has become a routine component of automated chemistry panels; screening calcium and parathyroid hormone (PTH) levels are being performed in patients with osteoporosis, osteopenia, and kidney stones. The best treatment for PHPT, and the only known cure, is surgical removal of the enlarged parathyroid gland(s). The optimal surgical approach for patients with PHPT has yet to be determined and is likely a combination of approaches depending on specific patient factors. There is an ongoing debate among experienced parathyroid surgeons regarding the extent of exploration during parathyroid surgery. The traditional approach of a bilateral, four-gland exploration was favored for many years before the development of preoperative localization scans and intraoperative PTH assays. Although more focused explorations became increasingly popular in the 1990s and early 2000s, the bilateral approach is coming back into favor due to the recognized incidence of multi-gland disease that is often difficult to detect before surgery. A complete knowledge of parathyroid embryology and anatomy is essential in the performance of a safe and successful four-gland parathyroid exploration. Furthermore, this can be performed in a minimally invasive fashion with complication rates comparable to more limited parathyroid explorations. This chapter focuses on the rationale, technique, and indications for bilateral parathyroid explorations.

Myocardial metastasis from a cutaneous squamous cell carcinoma (SCC) is rare. Herein we have presented a case of metastasis from cutaneous SCC to the myocardium in a renal transplant recipient, which was confirmed by a cardiac fine-needle biopsy. Postmortem examination revealed disseminated metastatic disease involving myocardium, lungs, thyroid, skin, and peritoneum secondary to cutaneous SCC likely related to immunosuppression. At 46 years of age, he received a renal transplant for chronic renal failure caused by chronic glomerulonephritis. He started to develop multiple nonmelanoma skin cancers 4 years later. At least 23 invasive SCCs and 14 basal cell carcinomas were excised. His immunosuppressive regimen consisted of cyclosporine (150 mg), azathioprine (75 mg), and prednisone (10 mg daily), which was not modified despite multiple nonmelanoma skin cancers. Our case report further illustrates the potentially aggressive and fatal nature of cutaneous SCCs that can develop in organ transplant recipients. It argues for modification of the immunosuppressive regimen in such patients. The management of renal transplant patients with nonmelanoma skin cancers remains difficult and complex.

Background: Patients with low-risk-PTC who undergo thyroid lobectomy (TL) have comparable disease-specific survival with lower morbidity than total thyroidectomy (TT). We aim to describe the surgical management of low-risk-PTC using the Collaborative Endocrine Surgery Quality Improvement Program (CESQIP). Method: CESQIP thyroidectomies of PTC tumors <4 cm were analyzed from 2014 to 2019 (n = 740). Postoperative outcomes were compared. Subgroup analysis examined temporal and institutional trends, and stratified for tumor size. Statistics utilized t-test, ANOVA, and Chi-squared. Results: TT patients had greater hypoparathyroidism, operative time, and length-of-stay (all p < 0.001). Incidence of TL decreased with increasing tumor size (24.2% for <1 cm, 15.8% for 1-2 cm, 6.1% for 2-4 cm). TL rates increased from 2.0% in 2014 to 21.2% in 2018-19. Completion thyroidectomy was recommended in 12.0% of TL subjects. There was significant variation in TL rate by institution (p<.001). Conclusions: For low-risk-PTC, TT remained the most commonly utilized operation. TL rates increased following release of the new ATA guidelines. TT was associated with higher perioperative morbidity. Further insight is needed to understand factors influencing operative approach. (C) 2020 Elsevier Inc. All rights reserved.

Background: Hürthle cell/oncocytic change is commonly reported on thyroid fine-needle aspiration (FNA) and may be considered an "atypical cell" by clinicians. This study aims to delineate the association between Hürthle cells in preoperative cytology and subsequent pathology of the indexed thyroid nodule and to report rates of malignancy. Methods: Retrospective review of records of 300 patients with Hürthle cell/oncocytic change on FNA and final surgical pathology at a tertiary referral center between 2000 and 2013 was performed and compared with a multi-institutional FNA cohort. The degree of Hürthle cell presence was correlated with histopathologic diagnoses. Results: In the Hürthle cell FNA group, Bethesda System for Reporting Thyroid Cytopathology (BSRTC) categories were as follows: I (nondiagnostic) 14 (4.7%); II (benign) 113 (37.7%); III (atypia of undetermined significance/follicular lesion of undetermined significance) 33 (11%); IV (follicular neoplasm/suspicious for a follicular neoplasm) 125 (41.6%); V (suspicious for malignancy) 12 (4%); and VI (malignant) 3 (1%). When categorized based on the degree of Hürthle cell change, 59 (29%) were classified as mild, 13 (6%) moderate, and 131 (65%) as predominant. When comparing the results with a multi-institutional FNA cohort (all with surgical confirmation), the presence of Hürthle cells was found to be associated with a lower risk of malignancy in all BSRTC categories, with a statistically significant difference in the BSRTC IV and V groups. The sole exception was when Hürthle cell presence was classified as predominant (defined as >75% of the cellular population); the rate of malignancy was significantly elevated in FNAs interpreted as benign/Bethesda II. Conclusions: Although Hürthle cells have been considered by clinicians as an "atypical cell," their presence does not increase the risk of malignancy within BSRTC categories overall. However, when predominant Hürthle cell change is present, the risk of malignancy is increased in the benign cytology/BSRTC category II.

Importance:Patient-generated health data captured from smartphone sensors have the potential to better quantify the physical outcomes of surgery. The ability of these data to discriminate between postoperative trends in physical activity remains unknown. Objective:To assess whether physical activity captured from smartphone accelerometer data can be used to describe postoperative recovery among patients undergoing cancer operations. Design, Setting, and Participants:This prospective observational cohort study was conducted from July 2017 to April 2019 in a single academic tertiary care hospital in the United States. Preoperatively, adults (age ≥18 years) who spoke English and were undergoing elective operations for skin, soft tissue, head, neck, and abdominal cancers were approached. Patients were excluded if they did not own a smartphone. Exposures:Study participants downloaded an application that collected smartphone accelerometer data continuously for 1 week preoperatively and 6 months postoperatively. Main Outcomes and Measures:The primary end points were trends in daily exertional activity and the ability to achieve at least 60 minutes of daily exertional activity after surgery among patients with vs without a clinically significant postoperative event. Postoperative events were defined as complications, emergency department presentations, readmissions, reoperations, and mortality. Results:A total of 139 individuals were approached. In the 62 enrolled patients, who were followed up for a median (interquartile range [IQR]) of 147 (77-179) days, there were no preprocedural differences between patients with vs without a postoperative event. Seventeen patients (27%) experienced a postoperative event. These patients had longer operations than those without a postoperative event (median [IQR], 225 [152-402] minutes vs 107 [68-174] minutes; P < .001), as well as greater blood loss (median [IQR], 200 [35-515] mL vs 25 [5-100] mL; P = .006) and more follow-up visits (median [IQR], 2 [2-4] visits vs 1 [1-2] visits; P = .002). Compared with mean baseline daily exertional activity, patients with a postoperative event had lower activity at week 1 (difference, -41.6 [95% CI, -75.1 to -8.0] minutes; P = .02), week 3 (difference, -40.0 [95% CI, -72.3 to -3.6] minutes; P = .03), week 5 (difference, -39.6 [95% CI, -69.1 to -10.1] minutes; P = .01), and week 6 (difference, -36.2 [95% CI, -64.5 to -7.8] minutes; P = .01) postoperatively. Fewer of these patients were able to achieve 60 minutes of daily exertional activity in the 6 weeks postoperatively (proportions: week 1, 0.40 [95% CI, 0.31-0.49]; P < .001; week 2, 0.49 [95% CI, 0.40-0.58]; P = .003; week 3, 0.39 [95% CI, 0.30-0.48]; P < .001; week 4, 0.47 [95% CI, 0.38-0.57]; P < .001; week 5, 0.51 [95% CI, 0.42-0.60]; P < .001; week 6, 0.73 [95% CI, 0.68-0.79] vs 0.43 [95% CI, 0.33-0.52]; P < .001). Conclusions and Relevance:Smartphone accelerometer data can describe differences in postoperative physical activity among patients with vs without a postoperative event. These data help objectively quantify patient-centered surgical recovery, which have the potential to improve and promote shared decision-making, recovery monitoring, and patient engagement.

Given their profound emotional, physical, and financial toll on patients and surgeons, we studied the characteristics, costs, and contributing factors of thyroid and parathyroid surgical malpractice claims.

In the past 20 years, interest in mindfulness and its cultivation through various meditative practices has increased astronomically. This is reflected in the popularity of mindfulness training programs, its ever-widening exposure in popular culture, and in the number of scientific articles published on the topic. With the recent focus on burnout in the medical profession and reports of high levels of anxiety and depression among residents and staff physicians, the potential applications of mindfulness are becoming increasingly apparent in the hospital setting. Mindfulness meditation may be particularly useful for surgeons because they are required to maintain their presence of mind and mental focus in the setting of challenging physical and mental tasks. Furthermore, personality traits such as perfectionism and intensity, which may have facilitated success in the competitive environment of medical school and residency training, may later manifest as intolerance and impatience, contributing to frustration and anger. A mindfulness meditation practice may help reduce the tendency to react to these emotions, yet still allow surgeons to remain motivated to excel. This article provides a definition of mindfulness and describes its introduction to Western culture. The connection of a regular meditation practice to improvements in focus and performance are reviewed. The potential benefits of mindfulness training to a surgical career are discussed, and an approach to introducing mindfulness and meditation to individual surgeons and surgical departments is outlined. We hypothesize that the introduction of department-wide training programs in mindfulness and meditation could benefit surgeons with regard to technical performance, empathy toward patients, academic productivity, and general life and career satisfaction.

Background: Thyroid cancer incidence is increasing. The effect of diagnosis and treatment on health-related quality of life (HRQoL) is an essential variable in the absence of a change in life span for the majority of patients. HRQoL instruments, with data useful for between-disease comparisons, are being increasingly used for health policy and outcomes evaluation. Variation exits among the instruments based on the impact of a specific disease. We assessed which of four well-validated, preference-based surveys detect changes in health and clinical intervention in patients diagnosed with papillary thyroid cancer (PTC). Methods: Four commonly used HRQoL questionnaires (Short Form-12v2® [SF6D], EuroQol-5D [EQ5D], and Health Utilities Index Mark 2 and 3 [HUI2, HUI3]) were administered to patients with the diagnosis of PTC at three perioperative time points during the first year of treatment. Clinicopathological and treatment course data were assessed for HRQoL impact including complications from surgery, re-operation for persistence/early recurrence, and adjuvant radioactive iodine treatment. We compared standard metrics, including ceiling effect, intraclass correlation coefficient, effect sizes, and quality-adjusted life-years between the four instruments. Results: Of 117 patients, 27% had a preoperative diagnosis of anxiety or depression, 41% had regional lymph node metastases, three had distant metastases and 49% underwent adjuvant radioactive iodine treatment. The ceiling effect (i.e., proportion with a perfect score) was greatest with EQ5D and least with SF6D. Index scores ranged from 0.77 (SF6D) to 0.90 (EQ5D). All scores declined at two weeks postoperatively and returned to pretreatment levels at six months. The SF6D was the only instrument to exceed the conventional minimally important difference between all three time points. Quality-adjusted life-years were as follows: SF6D, 0.79; EQ5D, 0.90; HUI2, 0.88; and HUI3, 0.86. Conclusions: Our results reflect the general good health of PTC patients. The effect on quality of life is primarily related to emotional and social impacts of treatment. The results support the measurement of a similar underlying construct, although variation in detecting changes in health exists between the instruments. Of the instruments assessed, the SF6D is the most responsive to treatment effects and should be utilized in future economic analyses in this patient population.

Importance Primary hyperparathyroidism (pHPT) is a common clinical entity, with approximately 100 000 new cases diagnosed each year in the United States. Most patients with pHPT have a relatively mild form of the disease and present with few if any overt signs or symptoms. This has led to a dilemma regarding which patients should be considered for parathyroid surgery. In this article, we review the established literature on the indications for surgery in asymptomatic pHPT and discuss the most recent consensus conference guidelines. Observations The reviewed literature suggests that there were improved outcomes among patients with asymptomatic pHPT who underwent curative surgery. Conclusions and Relevance Most patients with pHPT should be considered for parathyroidectomy. More randomized clinical trials are needed to strongly support a surgical recommendation for all asymptomatic patients with pHPT.
