RESUMO

OBJECTIVE: To explore changing trends and characteristics in neuroendocrine tumors (NETs) epidemiology, focusing on demographics, clinical aspects, and survival, including the impact of social determinants of health (SDOH) on outcomes. BACKGROUND: The escalating incidence and prevalence of NETs underscore the pressing need for updated epidemiologic data to reveal the evolving landscape of this condition. Access to current information is imperative for informing clinical strategies and public health initiatives targeting NETs. METHODS: A retrospective, population-based study analyzed NET patient data from 1975 to 2020, using the Surveillance, Epidemiology, and End Results (SEER 8, 12, 18) program. We calculated annual age-adjusted incidence, prevalence, and 5-year overall survival (OS) rates. Survival trends from 2000 to 2019 were examined, employing the Fine-Gray model to evaluate cancer-specific mortality. RESULTS: NETs' age-adjusted incidence rate quadrupled from 1.5 per 100,000 in 1975 to 6.0 per 100,000 in 2020. A decline in incidence occurred from 6.8 per 100,000 in 2019 to 6.0 per 100,000 in 2020. All-cause survival multivariable analysis demonstrated high grade (HR: 2.95, 95% CI: 2.63-3.09, P<0.001), single patients (HR: 1.49, 95% CI: 1.45-1.54, P<0.001), and Black patients (HR: 1.17, 95% CI:1.13-1.22, P<0.001) all had worse survival than their controls. CONCLUSION: In conclusion, our study shows a steady increase in NETs incidence until 2019, with a decline in 2020. Understanding the reasons behind this trend is vital for improved management and public health planning. Further research should focus on the factors driving these changes to enhance our understanding of NET epidemiology.

RESUMO

BACKGROUND: Hyperparathyroidism (HPT) and malignancy are the most common causes of hypercalcemia. Among kidney transplant (KT) recipients, hypercalcemia is mostly caused by tertiary HPT. Persistent tertiary HPT after KT is associated with allograft failure. Previous studies on managing tHPT were subjected to survivor treatment selection bias; as such, the impact of tertiary HPT treatment on allograft function remained unclear. We aim to assess the association between hypercalcemic tertiary HPT treatment and kidney allograft survival. MATERIALS AND METHODS: We identified 280 KT recipients (2015-2019) with elevated post-KT adjusted serum calcium and parathyroid hormone (PTH). KT recipients were characterized by treatment: cinacalcet, parathyroidectomy, or no treatment. Time-varying Cox regression with delayed entry at the time of first elevated post-KT calcium was conducted, and death-censored and all-cause allograft failure were compared by treatment groups. RESULTS: Of the 280 recipients with tHPT, 49 underwent PTx, and 98 received cinacalcet. The median time from KT to first elevated calcium was 1 month (IQR: 0-4). The median time from first elevated calcium to receiving cinacalcet and parathyroidectomy was 0(IQR: 0-3) and 13(IQR: 8-23) months, respectively. KT recipients with no treatment had shorter dialysis vintage (P = .017) and lower PTH at KT (P = .002), later onset of hypercalcemia post-KT (P < .001). Treatment with PTx (adjusted hazard ratio (aHR) = 0.18, 95%CI 0.04-0.76, P = .02) or cinacalcet (aHR = 0.14, 95%CI 0.004-0.47, P = .002) was associated with lower risk of death-censored allograft failure. Moreover, receipt of PTx (aHR = 0.28, 95%CI 0.12-0.66, P < .001) or cinacalcet (aHR = 0.38, 95%CI 0.22-0.66, P < .001) was associated with lower risk of all-cause allograft failure. CONCLUSIONS: This study demonstrates that treatment of hypercalcemic tertiary HPT post-KT is associated with improved allograft survival. Although these findings are not specific to hypercalcemia of malignancy, they do demonstrate the negative impact of hypercalcemic tertiary HPT on kidney function. Hypercalcemic HPT should be screened and aggressively treated post-KT.

RESUMO

INTRODUCTION: The Physician Payment Sunshine Act created the Open Payments Program (OPP), which is used to disclose transactions between physicians and industry. The impact of the coronavirus disease (COVID-19) pandemic on this relationship is yet to be determined. Our aim was to compare payments before and after the onset of COVID-19 through the OPP. METHODS: The OPP database was queried between 2014 and 2021 for all general surgery specialties. Payments were classified as general payments and research payments. Payments during 2014-2019 were classified as pre-COVID and compared to payments from 2020 to 2021 which were classified as post-COVID-Outbreak. RESULTS: From 2014 to 2021, 60,245 surgeons received general payments totaling $1.16 billion dollars. Comparing 2019 to 2020, general payments declined from $204.6 million to $108.5 million (-47%) and research payments from $157.3 million to $115.7 million (-26.5%). When comparing trends from 2014-2019 to 2020-2021, the mean number of payments was significantly higher at 394,782 versus 240,778 (P = 0.03) for general payments and 13,671 versus 10,382 (P = 0.03) for research payments. When comparing general payments among various surgical subspecialties, all fields saw a notable decline in general payments. Travel/lodging was the category of payment that saw the most significant change. CONCLUSIONS: Industry payments declined as we entered the COVID-19 pandemic for both general and research payments. This decrease was seen across all surgical subspecialties. These trends in payments seen during the COVID-19 pandemic and the long-term economic impact of COVID-19 on the physician-industry relationship are still developing. Ongoing changes in future years to industry payments are worthy of continued monitoring.

RESUMO

INTRODUCTION: The Matthew Effect refers to a pattern of accumulated advantage, specifically how social status can lead to increased wealth and recognition. The Physician Payments Sunshine Act of the Affordable Care Act requires industry payments and the affiliated hospital to be publicly available through the Open Payments Database (OPD). The US News and World Report (USNWR) publishes a ranking of best medical school (research) programs yearly. The Blue Ridge Institute for Medical Research (BRIMR) ranks medical schools annually by the amount of funding from the National Institutes of Health (NIH). Whether medical school-affiliated hospitals with higher social ranking and more NIH funding receive more industrial support is unknown. This study aims to evaluate the relationship between open payment of medical school-affiliated hospitals and USNWR and BRIMR ranking. METHODS: We performed a cross-sectional analysis of the OPD for the fiscal year of 2021. Hospital industry payment information was collected for affiliated hospitals in general and research categories. NIH funding data and program rankings were collected from BRIMR and USNWR, respectively. All data were collected for the fiscal year of 2021. The open payments of schools ranked in the top 50 for USNWR (n = 50) and BRIMR (n = 49) were compared to the schools not ranked in the top 50 using SPSS with chi-squared and Mann-Whitney U tests. A multivariate linear regression was performed to evaluate the association between open payments, USNWR ranking, and BRIMR ranking. RESULTS: A total of 91 medical schools were included in this study. The top 50 ranked medical schools by BRIMR were found to have a higher median of total open payment ($5,652,628 versus $2,558,372, P < 0.001), open payment in research ($4,707,297 versus $1,992,597, P = 0.003), and general open payment ($1,083,018 versus $392,045, P < 0.001). When ranked by USNWR, the top 50 ranked medical schools were found similarly to have a higher median of total open payment (P < 0.001), open payment in research (P < 0.001), and general open payment (P < 0.001). USNWR ranking was an independent predictor of more total open payment (Coefficient 0.016, 95% confidence interval 0.002-0.029, P = 0.026) and research open payment (coefficient 0.018, 95% confidence interval 0.002-0.034, P = 0.028). USNWR ranking was not found to predict general open payments. BRIMR ranking was not associated with open payment in total, research, or general. CONCLUSIONS: Hospital open payments were associated with the social reputation of their medical schools. NIH funding was not associated with open payments. A Matthew effect exists in current industry payments to medical school-affiliated hospitals.

RESUMO

INTRODUCTION: Health literacy (HL) is the ability to comprehend and apply health information to make informed health-care decisions. Poor HL results in the inability to provide informed consent, medication noncompliance, inconsistent follow-up, and delayed seeking of care. Data about HL in endocrine surgery is currently lacking. In this study, we aimed to evaluate the HL of patients with thyroid disease and identify risk factors for limited HL. METHODS: We evaluated a total of 172 patients with thyroid disease in a single endocrine surgery clinic. HL was determined by the Brief Health Literacy Screening Tool, a validated HL screening questionnaire in which patient scores correlate to limited, marginal, or adequate HL. Demographic data including age, sex, race, diagnosis, employment status, and median annual income were obtained. Analysis of variance, t-test, and Chi-square test were used to compare HL between and within each demographic domain. P < 0.05 was considered significant. RESULTS: Of the 172 patients, 77% had adequate HL, 16% had marginal HL, and 7% had limited HL. Patients with higher education exhibited greater HL (P < 0.001). Ninety-three percent of patients with college/postgraduate degree had adequate HL, while of those with some college only 79% had adequate HL and of those with high school or less only 48.6% had adequate HL. There was minimal variation among age, sex, race, diagnosis, employment status, or income. CONCLUSIONS: Most patients with thyroid diseases from the endocrine surgery clinic at our institution have adequate HL. Limited education is a risk factor for low HL.

RESUMO

INTRODUCTION: Traditional parathyroid registries are labor-intensive and do not always capture long-term follow-up data. This study aimed to develop a patient-driven international parathyroid registry and leverage community connections to improve patient-centered care for hyperparathyroidism. METHODS: An anonymous voluntary online survey was developed using Qualtrics and posted in an international patient and advocate-run social media group affiliated with over 11,700 members. The survey was developed from a literature review, expert opinion, and discussion with the social media group managers. It consists of seven sections: patient demographics, past medical history, preoperative symptoms, laboratory evaluation, preoperative imaging studies, operative findings, and operative outcomes. RESULTS: From July 30, 2022, to October 1, 2022, 89 complete responses were received. Participants were from 12 countries, mostly (82.0%) from the United States across 31 states. Most participants were female (91.4%), White (96.7%) with a mean (±standard deviation) age of 58 ± 12 y. The most common preoperative symptoms were bone or joint pain (84.3%) and neuropsychiatric symptoms: including fatigue (82.0%), brain fog (79.8%), memory loss (79.8%), and difficulty with concentration (75.3%). The median (interquartile range) length from symptom onset to diagnosis was 40.0 (6.8-100.5) mo. Seventy-one percent of participants had elevated preoperative serum calcium, and 73.2% had elevated preoperative parathyroid hormone. All participants obtained preoperative imaging studies (88.4% ultrasound, 86.0% sestabimi scan, and 45.3% computed tomography). Among them, 48.8% of participants received two, and 34.9% had three imaging studies. The median (interquartile range) time from diagnosis to surgical intervention was 3 (2-9) mo. Twenty-two percent of participants traveled to different cities for surgical intervention. Forty-seven percent of participants underwent outpatient parathyroidectomy. Eighty-four percent of participants reported improved symptoms after parathyroidectomy, 12.4% required oral calcium supplementation for more than 6 mo, 32.6% experienced transient hoarseness after parathyroidectomy, and 14.6% required reoperation after initial parathyroidectomy. CONCLUSIONS: This international online parathyroid registry provides a valuable collection of patient-entered clinical outcomes. The high number of responses over 10 wk demonstrates that participants were willing to be involved in research on their disease. The creation of this registry allows global participation and is feasible for future studies in hyperparathyroidism.

RESUMO

INTRODUCTION: Social networking platforms have evolved into a self-promotional space. The LinkedIn platform allows users to share knowledge, research accomplishments, and network in an academic setting. Our objective was to determine LinkedIn usage trends among surgeons at a large academic institution. METHODS: A list of surgeons within the department of surgery at a large academic institute was compiled. All publicly available profiles were analyzed for their LinkedIn activity and followership. Active accounts were defined as users who have posted or interacted with any posts within the last year. Comparisons of LinkedIn usage grouped by gender, surgery division, and rank were analyzed. RESULTS: A total of 133 surgeons were included. Among these surgeons, 88 had a LinkedIn profile (66.2%); however, only 43 surgeons had active usage on this platform (32.3%). The median number of followers among surgeons with a profile was 110 (IQR [24-427]). Male surgeons had a higher median of followers (167 IQR [38-502]) compared to female (54 IQR [21-209]). A greater percentage of male surgeons had a profile compared to female surgeons (68.5% M versus 61.0% F, P = 0.12). The transplant surgery division had the highest percentage of LinkedIn accounts (90.9%) followed by surgical oncology (87.5%). However, active usage was led by the pediatric surgery division (80.0%), followed by the plastic surgery division (71.4%). Instructors, assistant professors, associate professors, and professors all had LinkedIn accounts; however, instructors were the least active users with 33.3% being active on their LinkedIn. The lowest percentage of those with LinkedIn accounts were instructors (50%). Professors were found to be the most active users at 57.1%. CONCLUSIONS: Social media use is on the rise in academic surgery. Within a department of surgery at a large academic institution, only 32.3% were active users of LinkedIn, suggesting that there is room for improvement in utilizing this resource as a tool for mentorship, professional development, and networking.

RESUMO

INTRODUCTION: As our growing population demonstrates a significant increase in the incidence of thyroid cancer, so does patient access to their medical records. Poor health literacy and understanding of disease severity, underscores the importance of effective and accessible patient-doctor communication. No previous studies on patient understanding of thyroid pathology reports exist; therefore, we sought to characterize health literacy in this population. METHODS: Using a modified Delphi technique, a 12-question multiple-choice survey regarding common pathology terms with possible definitions for each term was synthesized and administered to patients in a high-volume endocrine surgery clinic. Survey results, patient demographics, history of prior thyroid procedure (biopsy or surgery), and self-reported health literacy were collected. Data analysis included t tests, chi-squared, and multivariable linear regression using R. RESULTS: The survey was completed by 54 patients (response rate: 69.8%). On univariate analysis, White race, previous thyroid procedure, and at least a high school level education were all more likely to score higher on the survey than their counterparts (P < 0.05). On multivariable logistic regression for predicting a higher survey score, only race (est: 2.48 [95% confidence interval: 1.01-3.96]) and higher educational attainment (est: 3.98 [95% confidence interval: 2.32-5.64]) remained predictive (P < 0.05). The remaining demographic groups (age, health literacy confidence, and previous thyroid procedure) did not show a statistically significant difference. CONCLUSIONS: Overall, terms on a thyroid pathology report are poorly understood by patients. This is exacerbated by non-White race and low educational attainment. There is a need for patient-facing pathology education.

RESUMO

INTRODUCTION: Total thyroidectomy (TTx) has been reported to be more challenging in patients with Graves' disease, especially in those who are hyperthyroid at the time of surgery. Our aim was to compare outcomes in patients undergoing TTx for Graves' disease compared to other thyroid diseases at a large academic institution with high-volume fellowship-trained endocrine surgeons. METHODS: In our retrospective analysis from December 2015 to May 2023, patients undergoing TTx for Graves' disease were compared to those undergoing TTx for all other indications excluding advanced malignancy (poorly differentiated thyroid cancer and concomitant neck dissections). Patient demographics, biochemical values, and postoperative outcomes were compared. A subgroup analysis was performed comparing hyperthyroid to euthyroid patients at the time of surgery. RESULTS: There were 589 patients who underwent TTx, of which 227 (38.5%) had Graves' disease compared to 362 (61.5%) without. Intraoperatively in Graves' patients, nerve monitoring was used more frequently (65.6% versus 57.1%; P = 0.04) and there was a higher rate of parathyroid autotransplantation (32.0% versus 14.4%; P < 0.01). Postoperatively, transient voice hoarseness occurred less frequently (4.8% versus 13.6%; P < 0.01) and there was no difference in temporary hypocalcemia rates or hematoma rates. In our subgroup analysis, 83 (36%) of Graves' patients were hyperthyroid (thyroid-stimulating hormone < 0.45 and free T4 > 1.64) at the time of surgery and there were no differences in postoperative complications compared to those who were euthyroid. CONCLUSIONS: At a high-volume endocrine surgery center, TTx for Graves' disease can be performed safely without significant differences in postoperative outcomes. Hyperthyroid patients demonstrated no differences in postoperative outcomes.

RESUMO

BACKGROUND: While males present with more adverse clinicopathologic features in papillary thyroid carcinoma (PTC), younger age has previously been shown to be a favorable prognostic factor. We examined the combined effect of male sex and young age on PTC outcomes. METHODS: We conducted a retrospective analysis of a prospectively maintained database of thyroid cancer surgery patients (2000-2020) at a single quaternary care institution. We included papillary thyroid carcinoma cases and excluded those with prior cancer-related thyroid surgery. We examined demographics, cancer stage, surgical outcomes, and complications by age and sex, analyzing groups below and above the age of 40 years. RESULTS: A total of 680 patients with PTC were included. Females constituted 68% (age ≥40 years: 44% and <40 years: 24%) and males 32% (≥40 years: 24% and <40 years: 8%). A significant difference (p < 0.001) of N1 disease distribution was found between the groups. N1a metastasis was greater in patients younger than 40 regardless of sex ((M < 40 (15%), F < 40 (15%), M ≥ 40 (12%), and F ≥ 40 (9%)). While, M < 40 had greater N1b metastasis (36%) than all other groups (M ≥ 40 (28%), F < 40 (22%), and F ≥ 40 (10%)). There was no significant difference in the distribution of T stages between groups. Groups showed no differences in 30-day outcomes, recurrence at 1 year, reoperation, mortality, nerve injury, or hypocalcemia. CONCLUSIONS: Young males with PTC face increased occurrence of nodal metastasis yet experience similar recurrence rates as their female and older counterparts. Subgroup analysis underscores the predictive role of sex and age in advanced PTC cases.

RESUMO

OBJECTIVE: The management of secondary hyperparathyroidism in patients undergoing dialysis is debated, with uncontrolled parathyroid hormone (PTH) levels becoming more common despite the expanded use of medical treatments like cinacalcet. This study examines the clinical benefits of parathyroidectomy vs medical treatment in reducing mortality and managing key laboratory parameters in patients undergoing dialysis. METHODS: PubMed, Embase, Cochrane, Scopus, and Web of Science databases were searched for cohort studies or randomized controlled trials published before August 18, 2023. We included studies with comparative arms, specifically medical treatment vs surgical intervention. Patients with a history of kidney transplant were excluded. Outcomes were analyzed using hazard ratios (HRs) for mortality and weighted mean differences (WMD) for laboratory parameters. RESULTS: Twenty-three studies involving 24 398 patients were analyzed. The pooled meta-analysis has shown a significant reduction in all-cause (HR, 0.47; 95% confidence interval [CI], 0.35-0.61) and cardiovascular mortality (HR, 0.58; 95% CI, 0.40-0.84) for parathyroidectomy vs medical treatments. Subgroup analysis showed that parathyroidectomy was associated with a greater reduction in mortality in patients with a PTH level over 585 pg/mL (HR, 0.37; 95% CI, 0.24-0.58). No mortality difference was found when all patients in the medical group received cinacalcet alongside standard medical treatment (HR, 1.02; 95% CI, 0.49-2.11). Parathyroidectomy also led to a larger decrease in PTH (WMD, 1078 pg/mL; 95% CI, 587-1569), calcium (WMD, 0.86 mg/dL; 95% CI, 0.43-1.28), and phosphate (WMD, 0.74 mg/dL; 95% CI, 0.32-1.16). CONCLUSION: Parathyroidectomy may offer a survival advantage compared to medical management in patients with severe secondary hyperparathyroidism.

RESUMO

OBJECTIVE: Hyperparathyroidism (HPT) is nearly universal in patients with end-stage kidney disease. Kidney transplantation (KT) reverses HPT in many patients, but most studies have only focused on following calcium and not parathyroid hormone (PTH) levels. We sought to study the prevalence of persistent HPT post-KT at our center and its effect on graft survival. METHODS: Patients who underwent KT from January 2015 to August 2021 were included and characterized by post-KT HPT status at the most recent follow-up: resolved (achieving normal PTH post-KT) versus persistent HPT. Those with persistent HPT were further stratified by the occurrence of hypercalcemia (normocalcemic versus hypercalcemic HPT). Patient demographics, donor kidney quality, PTH and calcium levels, and allograft function were compared between groups. Multivariable logistic regression and Cox regression with propensity score matching were conducted. RESULTS: Of 1554 patients, only 390 (25.1%) patients had resolution of renal HPT post-KT with a mean (±SD) follow-up length of 40±23 months. The median (IQR) length of HPT resolution was 5 (0-16) months. Of the remaining 1164 patients with persistent HPT post-KT, 806 (69.2%) patients had high PTH and normal calcium levels, while 358 (30.8%) patients had high calcium and high PTH levels. Patients with persistent HPT had higher parathyroid hormone (PTH) at the time of KT [403 (243-659) versus 277 (163-454) pg/mL, P <0.001] and were more likely to have received cinacalcet treatment before KT (34.9% vs. 12.3%, P <0.001). Only 6.3% of patients with persistent HPT received parathyroidectomy. Multivariable logistic regression showed race, cinacalcet use pre-KT, dialysis before KT, receiving an organ from a deceased donor, high PTH, and calcium levels at KT were associated with persistent HPT post-KT. After adjusting for patient demographics and donor kidney quality by propensity score matching, persistent HPT (HR 2.5, 95% CI 1.1-5.7, P =0.033) was associated with a higher risk of allograft failure. Sub-analysis showed that both hypercalcemic HPT (HR 2.6, 95% CI 1.1-6.5, P =0.045) and normocalcemic HPT (HR 2.5, 95% CI 1.3-5.5, P =0.021) were associated with increased risk of allograft failure when compared with patients with resolved HPT. CONCLUSION: Persistent HPT is common (75%) after KT and is associated with a higher risk of allograft failure. PTH levels should be closely monitored after kidney transplantation so that patients with persistent HPT can be treated appropriately.

RESUMO

Somatostatin receptor type 2 (SSTR2) and thyroid-stimulating hormone receptor (TSHR) display variable expression in primary thyroid tumors and have been implicated as theranostic targets. This study was designed to explore the differential expression of SSTR2 and TSHR in oncocytic (Hurthle cell) carcinoma (OC) vs oncocytic adenoma (OA). We performed a retrospective review for oncocytic neoplasms treated at our institution from 2012 to 2019. Formalin-fixed paraffin-embedded tissue blocks were used for tissue microarray construction. Tissue microarray blocks were cut into 5-µm sections and stained with anti-SSTR2 and anti-TSHR antibodies. Immunostains were analyzed by 3 independent pathologists. χ2 and logistic regression analysis were used to analyze clinical and pathologic variables. Sixty-seven specimens were analyzed with 15 OA and 52 OC. The mean age was 57 years, 61.2% were women, and 70% were White. SSTR2 positivity was noted in 2 OA (13%) and 15 OC (28%; 10 primary, 4 recurrent, and 1 metastatic) (P = .22). TSHR positivity was noted in 11 OA (73%) and 32 OC (62%; 31 primary and 1 metastatic) (P = .40). Those who presented with or developed clinical recurrence/metastasis were more likely to be SSTR2-positive (50% vs 21%; P = .04) and TSHR-negative (64.3% vs 28.9%; P = .02) than primary OC patients. Widely invasive OC was more likely to be SSTR2-positive compared to all other OC subtypes (minimally invasive and angioinvasive) (P = .003). For all patients with OC, TSHR positivity was inversely correlated with SSTR2 positivity (odds ratio, 0.12; CI, 0.03-0.43; P = .006). This relationship was not seen in the patients with OA (odds ratio, 0.30; CI, 0.01-9.14; P = .440). Our results show that recurrent/metastatic OC was more likely to be SSTR2-positive and TSHR-negative than primary OC. Patients with OC displayed a significant inverse relationship between SSTR2 and TSHR expression that was not seen in patients with OA. This may be a key relationship that can be used to prognosticate and treat OCs.

RESUMO

INTRODUCTION: Total thyroidectomy (TT) has been shown to be a safe and effective treatment for Graves' disease. However, the time course for improvement of symptoms has not been defined. METHODS: With an institutional review board approval, we prospectively gathered survey data of all patients (n = 79) undergoing TT for Graves' disease at a single institution from 2019 to 2021. After informed consent was obtained, patients completed surveys preoperatively and at 2 wk followed by monthly postoperative visits/phone calls. Patient demographics and survey results were collected and analyzed. Symptom recovery time was evaluated using Kaplan-Meier analysis. RESULTS: A total of 50 patients completed the survey on postoperative follow-up (response rate 63%). Average age was 38 y (range 12-80 y) and 88% of patients were female. The most common preoperative symptoms were fatigue (90%) and heat/cold intolerance (88%). Tremor (median time to resolution: 1 wk; interquartile range [IQR] 1-3), diarrhea (median 1 wk [IQR 1-3]), and palpitations (median 1 wk [IQR 1-3]) resolved the most rapidly followed by eye symptoms (median 3 wk [IQR 1-6]), heat/cold intolerance (median 3 wk [IQR 3-30]), memory deficits (median 3 wk [IQR 1-undefined]), and fatigue (median: 3 wk [IQR 1-14]). There were no significant differences in time to resolution of symptoms by gender or age (less than versus 40 y and older). Those with uncontrolled Graves' had more severe symptoms but no difference in time to resolution from the euthyroid Graves' patients. CONCLUSIONS: Many Graves' disease symptoms improve rapidly following TT, with a median time to improvement of less than 1 mo.

RESUMO

INTRODUCTION: Hypocalcemia is commonly reported after thyroidectomy and has multiple possible etiologies including: parathyroid devascularization, reactive hypoparathyroidism from relative hypercalcemia in thyrotoxicosis, and abrupt reversal of thyrotoxic osteodystrophy. In patients that are actively hyperthyroid and undergoing thyroidectomy, it is not known how many experience hypocalcemia from nonhypoparathyroidism etiologies. Therefore, our aim was to examine the relationship among thyrotoxicosis, hypocalcemia, and hypoparathyroidism. METHODS: A retrospective review was performed of prospectively-collected data from all patients undergoing thyroidectomy for hyperthyroidism by 4 surgeons from 2016 to 2020. All patients carried a diagnosis of Graves' disease or toxic multinodular goiter. Patient demographics, preoperative medications, laboratory reports, and postoperative medications were reviewed. Hypocalcemia within the first month of surgery despite a normal parathyroid hormone (PTH) level was the primary outcome of interest and was compared between patients with and without thyrotoxicosis. Secondary outcomes were duration of postoperative calcium use and the relationship between preoperative calcium supplementation and postoperative calcium supplementation. Descriptive statistics, Wilcoxon rank-sum, and chi-square tests were used for bivariate analysis, as appropriate. RESULTS: A total of 191 patients were identified, with mean age of 40.5 y (range 6-86). Most patients were female (80%) and had Graves' disease (80%). At the time of surgery, 116 (61%) had uncontrolled hyperthyroidism (thyrotoxic group, Free Thyroxine >1.64 ng/dL or Free Triiodothyronine > 4.4 ng/dL), with the remaining 75 (39%) considered euthyroid. Postoperative hypocalcemia (calcium < 8.4 mg/dL) developed in 27 (14%), while hypoparathyroidism (PTH < 12 pg/mL) was observed in 39 (26%). Thyrotoxic patients comprised a majority of those with hypocalcemia (n = 22, 81%, P = 0.01) and hypoparathyroidism immediately following surgery (n = 14, 77%, P = 0.04). However, a majority of initially hypocalcemic, thyrotoxic patients had normal PTH values within the first month after surgery (n = 17, 85%), pointing to a potential nonparathyroid etiology. On bivariate analysis, no significant relationship was found for thyrotoxic patients with initial postoperative hypocalcemia (18%) and hypoparathyroidism <1-month after surgery (29%, P = 0.29) or between 1 and 6 mo after surgery (2%, P = 0.24). Of the 19 patients in the nonhypoparathyroidism group, 17 (89%) were off all calcium supplements by 6 mo postop. CONCLUSIONS: In patients with hyperthyroidism, those in active thyrotoxicosis at time of surgery have a higher rate of postoperative hypocalcemia compared to euthyroid patients. When hypocalcemia lasts >1 mo postoperatively, data from this study suggest that hypoparathyroidism may not be the primary etiology in many of these patients, who typically require calcium supplementation no more than 6 mo postoperatively.

RESUMO

INTRODUCTION: Well-differentiated thyroid cancer (WDTC) is the most common thyroid malignancy, and the worldwide incidence is increasing. Early stage disease is curable with surgery. We hypothesized that patients who live at greater distances from health care institutions or have complicating socioeconomic barriers may present with more advanced diseases and have worse outcomes. METHODS: The National Cancer Database (NCDB) was used to identify patients who were diagnosed with WDTC between 2004 and 2018. Race, ethnicity, insurance status, income status, and distance from residence to health care clinic of diagnosis (great circle distance [GCD]) were analyzed with respect to the severity of disease at presentation (stage) and outcomes. Binary logistic regression and Cox regression were used to determine associations between socioeconomic variables and tumor stage or survival. RESULTS: The Hispanic (OR: 1.49, CI: 1.45-1.54, P < 0.001) and Asian (OR: 1.49, CI: 1.43-1.55, P < 0.001) populations had higher odds of developing an advanced disease when compared to the White population separately. Patients without insurance displayed higher odds of developing an advanced disease at diagnosis compared to those with insurance (OR: 1.39, CI: 1.31-1.47, P < 0.001). Adjusted-Cox regression analysis of survival revealed that Black patients had detrimental survival outcomes when compared to White patients (HR: 1.24, P < 0.001), and patients with private insurance had improved survival outcomes when compared to those without insurance (HR: 0.58, P < 0.001). CONCLUSIONS: Hispanic and Asian patients were found to be more likely to present with an advanced disease but also displayed greater overall survival when compared to the White population. The Black population, patients without insurance, and patients with lower income status exhibited worse survival outcomes.

RESUMO

OPINION STATEMENT: Anaplastic thyroid cancer (ATC) is a rare but very aggressive form of undifferentiated thyroid cancer. Due to its rapid rate of progression and invasive nature, ATC poses significant risks of morbidity and mortality. The cornerstone in the management of ATC remains a prompt diagnosis of the disease and timely management of complications depending on the stage of disease. Surgery continues to offer a higher chance of a cure, although not all patients are candidates for surgical management. Patients with advanced disease may be considered for palliative surgery to reduce morbidity and complications from advanced disease. With the advent of new molecular testing and improved methods of diagnosis, novel therapeutic targets have been identified. Systemic therapy (chemotherapy and radiation therapy) as well as novel immunotherapy have shown some promise in patients with targetable genetic mutations. Patients should therefore have molecular testing of their tumor-if it is unresectable-and be tested for mutations that are targetable. Mutation-targeted therapy may be effective and may result in a significant response to allow surgical intervention for exceptional responders. Overall, patients who receive all three modalities of therapy (surgery, chemotherapy, and radiation therapy) have the highest overall survival.

RESUMO

CONTEXT: There are differences in diagnosis, treatment, and outcomes for thyroid between racial and ethnic groups that contribute to disparities. Identifying these differences and their causes are the key to understanding and reducing disparities in presentation and outcomes in endocrine disorders. EVIDENCE ACQUISITION: The present study reviews original studies identifying and exploring differences between benign and malignant thyroid diseases. A PubMed, Web of Science, and Scopus search was conducted for English-language studies using the terms "thyroid," "thyroid disease," "thyroid cancer," "race," "ethnicity," and "disparities" from inception to December 31, 2022. EVIDENCE SYNTHESIS: Many racial and ethnic disparities in the diagnosis, presentation, treatment, and outcomes of thyroid disease were found. Non-White patients are more likely to have a later time to referral, to present with more advanced disease, to have more aggressive forms of thyroid cancer, and are less likely to receive the appropriate treatment than White patients. Overall and disease-specific survival rates are lower in Black and Hispanic populations when compared to White patients. CONCLUSIONS: Extensive disparities exist in thyroid disease diagnosis, treatment, and outcomes that may have been overlooked. Further work is needed to identify the causes of these disparities to begin to work toward equity in the care of thyroid disease.

RESUMO

BACKGROUND: To encourage progression of surgeon scientists amongst increasingly limited funding, academic interest, training institutions are supporting mid-training academic development time (ADT). We propose that supporting ADT with a full funding mechanism will improve ADT participation at minimal institutional cost. MATERIALS AND METHODS: From 2017 to 2022, our surgery department proposed a full funding mechanism for a post-graduate year three (PGY-3) resident to encourage ADT participation. Residents were required to submit at least two external grants. Annual funding sources and total stipend supplementation was calculated by prevalence of ADT residents. RESULTS: From 2017 to 2022, 30 residents opted to participate in 1-4 years of ADT with increasing prevalence. 5 funding sources were utilized with ∼$530,000 in total annual funding. Departmental contribution was minimal compared to external (9% vs. 91% ($48,102 vs. $485,573, p â€‹< â€‹0.001)). CONCLUSIONS: With commitment of full salary supplementation, residents choosing ADT increased at marginal institutional cost, suggesting a solution to combating the declining number of academic surgeons.

RESUMO

BACKGROUND: The purpose of this study was to qualitatively explore patient-reported barriers to surgery for primary hyperparathyroidism (PHPT) and identify actionable interventions to improve access to surgical care. METHODS: We recruited forty-nine patients in an endocrine surgery clinic at a large, academic medical to participate in an 11- question phone interview. All interviewees underwent parathyroidectomy for primary hyperparathyroidism. Responses were recorded and a codebook of qualitative themes, blinded to patient race and sex, was created by 3 independent reviewers. Comments were subsequently sorted into the codebook with patient demographic information. RESULTS: Patients that experienced delays in parathyroidectomy most commonly cited "issues with the referral process" and "missed diagnosis" as the cause. Patients were asked to identify the most challenging part about the surgery process. Commonly evoked themes among patients of both races and sexes included "transportation" and "financial" with subthemes of "no ride," "distance from surgeon," "insurance," and "difficulty taking time off work." Patients were asked to name actionable interventions to improve access to surgical care. The most commonly evoked theme involved "support systems," with subthemes of "transportation assistance," "financial," and "patient advocacy." Physician factors were also commonly evoked among patients of both races with subthemes of "knowledge", "communication," and "listening." CONCLUSION: PHPT patients cited multiple barriers to undergoing surgery. Future work can focus on examining these questions with a larger patient cohort and examining delays at the referral and diagnosis stage, which was most commonly cited by our respondents.
