The aim of this study was to develop a prognostic model for radioactive iodine (RAI) therapy outcome in patients with Graves‘ disease. We enrolled 127 patients. Information on RAI therapy, ultrasound indexes of thyroid, and other lifestyle factors was collected. The competing risk model was used to estimate the multivariable-adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) for nonhealing or recurrence of hyperthyroidism (NHRH). The performance of the model was assessed by receiver operator characteristic analysis and the Brier score and internally validated by bootstrap resampling. Then, a nomogram was developed. Forty-one cases (32.2%) of NHRH were documented. Positive Ki-67 expression, a higher dose of per-unit thyroid volume, and females showed lower risks of NHRH (all P < 0.05). The HR values (95% CI) were 0.42 (0.23, 0.79), 0.01 (0.00, 0.02), and 0.47 (0.25, 0.89), respectively. The bootstrap validation showed that the model had the highest accuracy and good calibration for predicting cumulative risk of NHRH at 180 days after RAI therapy (AUC = 0.772; 95% CI: 0.640–0.889, Brier score = 0.153). By decision curve analysis, the nomogram was shown to have a satisfactory net benefit between thresholds of 0.20 and 0.40. Ki-67, ultrasound volumetry, and scintigraphy techniques can play important roles in evaluating RAI therapy outcome in Graves‘ disease patients. The prediction nomogram shows reasonable accuracy in predicting NHRH.

Objective
Serum 25-hydroxyvitamin D (25(OH)D) deficiency has been known to be associated with the risk and mortality of several cancers. However, the role of 25(OH)D in papillary thyroid cancer (PTC) remains controversial. This study aimed to investigate the association between 25(OH)D and clinicopathologic features of PTC.
Methods
Patients who underwent thyroidectomy were retrospectively reviewed. Serum 25(OH)D levels were measured within a week prior to surgery. The patients were categorized into four quartiles according to season-specific 25(OH)D levels. The association between 25(OH)D levels and clinicopathologic features of PTC was analyzed.
Results
A total of 2932 patients were enrolled in the study. The 25(OH)D levels were significantly higher in patients with lymph node metastasis (LNM; P < 0.001), lateral LNM (P < 0.001), and multifocal tumors (P < 0.001). Compared to the first quartile (Q1) of 25(OH)D level, the third quartile (Q3) and the fourth quartile (Q4) showed an unadjusted OR of 1.36 (95% CI: 1.09–1.69; P = 0.006) and 1.76 (95% CI: 1.42–2.19; P < 0.001) for LNM (P for trend < 0.001), respectively. An increased risk of multifocal tumors was strongly associated with high 25(OH)D concentration (P for trend <0.001). Similar results were obtained after adjusting for confounding factors.
Conclusion
High 25(OH)D levels are associated with aggressive features of PTC, such as lymph node metastasis and multifocality.

Background
The diagnostic and prognostic value of the leucine-rich alpha-2-glycoprotein 1 (LRG1) gene in thyroid cancer remains unclear. Using the Cancer Genome Atlas (TCGA) database, we conducted a bioinformatics analysis to determine the role of LRG1 in thyroid cancer.
Methods
Data from 512 patients with thyroid cancer and 59 normal individuals were collected from TCGA database. The Kruskal–Wallis test and logistic analysis were used to examine the relationship between LRG1 expression and clinicopathologic characteristics. Cox regression and Kaplan–Meier analysis were used to determine the predictive value of LRG1 on clinical outcomes. Single-sample gene set enrichment analysis (ssGSEA) was used to reveal associations between LRG1 expression and immune infiltration levels in thyroid cancer.
Results
LRG1 was highly expressed in thyroid cancer (P < 0.001) and could effectively distinguish tumor tissue (area under the curve = 0.875) from normal tissue. Moreover, LRG1 was significantly correlated with pathological N stage (odds ratio (OR) = 2.411 (1.659–3.505), P < 0.001). Kaplan–Meier survival analysis revealed that patients with high LRG1 expression had better overall survival (hazard ratio (HR) = 0.30, P = 0.038). Cox regression analysis indicated that pathological M stage was a risk factor for progression-free interval (HR = 5.964 (2.010–17.694), P < 0.001). Using ssGSEA, we found that LRG1 expression was positively correlated with the number of T helper 1 cells (R = 0.435, P < 0.001), dendritic cells (R = 0.442, P < 0.001), and macrophages (R = 0.459, P < 0.001).
Conclusion
LRG1 may be an important biomarker for predicting the prognosis of thyroid cancer and represent a suitable target for immunotherapy associated with immune infiltration.

Objective
The aim was to explore the effects of preoperative calcium and activated vitamin D3 supplementation on post-thyroidectomy hypocalcemia and hypo-parathyroid hormone-emia (hypo-PTHemia).
Methods
A total of 209 patients were randomly divided into control group (CG) and experimental group (EG). Oral calcium and activated vitamin D3 supplementation were preoperatively administered to EG, whereas a placebo was administered to CG. Data on serum calcium, phosphorus, and PTH concentrations before operation, on postoperative day 1 (POPD1), at postoperative week 3 (POPW3), and on the length of postoperative hospitalization were collected.
Results
The serum calcium, phosphorus, and PTH concentrations, as well as the incidence of postoperative hypocalcemia and hypo-PTHemia, did not significantly differ between EG and CG. Subgroup analysis revealed that the serum calcium concentrations of the experimental bilateral thyroidectomy subgroup (eBTS) on POPD1 and POPW3 were higher than that of the control bilateral thyroidectomy subgroup (cBTS) (P < 0.05); the reduction of serum calcium in eBTS on POPD1 and POPW3 was less than those in cBTS (P < 0.05). However, significant differences were not observed between the unilateral thyroidectomy subgroups (UTS) (P > 0.05). Moreover, the incidence of postoperative hypocalcemia in cBTS on POPD1 was significantly higher than that in eBTS (65.9% vs 41.7%) (P < 0.05). The length of hospitalization in cBTS (3.55 ± 1.89 days) was significantly longer than that (2.79 ± 1.15 days) in eBTS (P < 0.05).
Conclusion
Short-term preoperative prophylactic oral calcium and activated vitamin D3 supplementation could effectively reduce the incidence of postoperative hypocalcemia and decrease the length of postoperative hospitalization in patients who have undergone bilateral thyroidectomy.

Purpose
The aim was to investigate the effect of radioactive iodine (RAI) treatment for differentiated thyroid cancer (DTC) on male gonadal function.
Methods
PubMed, Embase, Web of Science, OVID, Scopus, and Wanfang databases were searched up to June 10, 2022, to identify published studies related to RAI and male gonadal function. ReviewManager version 5.4.1 software was used to calculate mean differences (MDs) with 95% CIs.
Results
Initially, 1958 articles were retrieved from the databases, and 6 articles were included in the quantitative analysis. The meta-analysis results showed that follicle-stimulating hormone (FSH) increased when the follow-up duration was ≥12 months after RAI, but the difference was not statistically significant (MD = −2.64, 95% CI = (−5.61, 0.33), P = 0.08). But the results of the subgroup analysis showed that when the follow-up time was ≤6 months, FSH levels were significantly higher after RAI (MD = −7.65, 95% CI = (−13.95, −1.34), P = 0.02). The level of inhibin B was significantly lower at ≥12 months and ≤6 months after RAI (MD = 66.38, 95% CI = (8.39, 124.37), P = 0.02) and (MD = 116.27, 95% CI = (43.56, 188.98), P = 0.002). Additionally, luteinizing hormone (LH) and testosterone have similar results – that is, LH and testosterone levels were higher after RAI, but the difference was not statistically significant (MD = –0.87, 95% CI = (−2.04, 0.30), P = 0.15) and (MD = −1.69, 95% CI (−7.29, 3.90), P = 0.55).
Conclusions
Male gonadal function may be temporarily impaired within 6 months after RAI but may return to normal levels afterward.

Objective
An improvement in iodine status in Veneto Region has been documented in the last decade. We aimed at estimating the incidence of hyperthyroidism in the Veneto Region (Italy) over the period 2013–2022.
Methods
Retrospective population-based study conducted in Veneto (4.9 million people) using the population registry, an administrative health database. Between 2012 and 2022, hyperthyroidism incidence was defined thank to a health-care co-payment exemption for hyperthyroidism or any hospital diagnosis of hyperthyroidism. Incident hyperthyroidism was defined from 2013 to 2022 to exclude prevalent cases. Standardized incidence rates (IRs) were reported by age, sex, and etiology of thyroid hyperfunction too.
Results
We identified 26,602 incident cases (IR of 54.38 per 100,000 person-years, 2.47-fold higher in females than in males). IR decreased from 69.87 (95% CI: 67.49, 72.25) in 2013 to 42.83 (95% CI: 40.99, 44.66) in 2022. In 2020, an out-of-trend decrease in hyperthyroidism incidence was documented, corresponding to the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic outbreak, with a realignment to the trend in the subsequent years. The annual percentage change according to the cause of hyperthyroidism was as follows: −6.62% (95% CI: 8.47, 4.73) (P < 0.0001) in toxic multinodular goiter, −7.56% in toxic uninodular goiter (95% CI: 10.54, 4.48) (P < 0.001) and −4.70% (95% CI: 6.33, 3.04) in toxic diffuse goiter (Graves’ disease) (P < 0.001).
Conclusions
We documented a decline in the incidence of hyperthyroidism in Veneto Region, paralleling the improvement of the iodine status, thanks to a long and sustained iodine prophylaxis campaign. SARS-CoV-2 pandemic and vaccination campaign did not change the declining trend of hyperthyroidism incidence in our study region.
Significance statement
An improvement in iodine status in the population residing in the Veneto region has been documented in the last decade, thanks to a nationwide voluntary iodine prophylaxis program running since 2005, but its impact on the epidemiology of thyroid disease has never been documented. This is the largest study on the incidence rates of hyperthyroidism carried out in Italy and covers the longest observation period among all regionwide population-based studies of hyperthyroidism in our country. We documented a reduction in the incidence of hyperthyroidism, which was more pronounced in nodular goiter diagnosis but involved also toxic diffuse goiter. The decline in the incidence of hyperthyroidism in Veneto Region shows the efficacy and safety of the iodine prophylaxis campaign.

Hypothyroidism is associated with a decreased health-related quality of life (HRQoL). We hypothesized that individuals with hypothyroidism (defined as use of thyroid hormone (TH)) and especially those having an impaired HRQoL are characterized by a high prevalence of comorbid disorders and that the impact of hypothyroidism and comorbidity on HRQoL is synergistic. Presence of comorbidity was based on data obtained using structured questionnaires, physical examination, biochemical measurements and verified medication use. Single morbidities were clustered into 14 different disease domains. HRQoL was measured using the RAND-36. Logistic regression analyses were used to determine the effect of TH use on the odds of having an affected disease domain and a lower score than an age- and sex-specific reference value for HRQoL. TH was used by 4537/14,7201 participants of the population-based Lifelines cohort with a mean (± s.d.) age of 51.0 ± 12.8 years (88% females). Eighty-five percent of the TH users had ≥1 affected disease domain in contrast to 71% of nonusers. TH use was associated with a higher odds of 13 out of 14 affected disease domains independent of age and sex. In a multivariable model, TH use was associated with a decreased HRQoL across six out of eight dimensions. No significant interactions between TH use and affected disease domains were observed. TH users with an impaired HRQoL had significantly more comorbidity than those not having an impaired HRQoL. In this large, population-based study, we demonstrated that TH users had more comorbidity than individuals not using TH. The coexistence of other chronic medical conditions in subjects with TH use led to further lowering of HRQoL in an additive manner.

Objective
The inflammatory microenvironment has been implicated in differentiated thyroid cancer (DTC). Inflammatory stimuli induce the release of components of neutrophils into extracellular space, leading to formation of neutrophil extracellular trap (NET), which can stimulate growth and progression of cancer. Generation of activated factor XII and thrombin is also involved in cancer progression. This study attempted to determine whether the level of circulating markers of NET, activated factor XII, and endogenous thrombin potential may be useful for detecting the recurrence of DTC.
Methods
A total of 122 patients with DTC were recruited during the postoperative follow-up period. Measurement of the levels of circulating markers of NET (neutrophil elastase, histone–DNA complex, cell-free dsDNA), activated factor XII, and endogenous thrombin potential was performed.
Results
A significantly elevated level of neutrophil elastase was detected in patients with recurrence (n = 12) compared to those without recurrence (n = 110), while significant elevation of the levels of other markers was not observed. The value for area under the curve (0.717, P = 0.018) of neutrophil elastase for detecting recurrence of DTC was superior to that (0.661, P = 0.051) of serum thyroglobulin. An elevated level of neutrophil elastase was significantly associated with recurrence of DTC independent of serum thyroglobulin.
Conclusions
Because an elevated level of neutrophil elastase was detected in patients with recurrence of DTC and showed a significant association with recurrence of DTC, it can be proposed as a novel biomarker for use in detecting recurrence of DTC along with other tests.

Objective
The optimal corticosteroid treatment regimen for subacute thyroiditis has not yet been established. To avoid side effects, tapering of the initial dose of corticosteroid is recommended. With reducing dose, the symptoms can recur.
Design
In a prospective clinical study, a 30-day methylprednisolone (MPSL) treatment protocol with a starting dose of 24 mg/day and tapered by 4 mg every 5 days was assessed for effectiveness and safety regarding possible adrenal insufficiency.
Methods
Fifty-nine patients with subacute thyroiditis were included. At visit 1, after establishing the diagnosis, a short stimulation adrenocorticotrophic hormone (ACTH) test was performed and methylprednisolone treatment was prescribed. At visit 2 (40 ± 5 days after visit 1), clinical, laboratory (including short stimulation ACTH test), and ultrasound evaluation were repeated.
Results
Forty-eight patients (81.4%) were cured by the prescribed protocol, having significantly lower cortisol levels after stimulation at visit 1 than patients who were not cured (mean, 674.9 nmol/L and 764.0 nmol/L, respectively, P = 0.012). Seven patients (12.3%) developed adrenal insufficiency; this group had significantly lower cortisol levels after stimulation at visit 1 than patients without adrenal insufficiency development (mean, 561.5 nmol/L and 704.7 nmol/L, respectively, P = 0.005). Using stimulated cortisol level at visit 1 as the explanatory variable, logistic models were optimized to determine treatment efficacy (AUC = 0.745, optimal threshold 729 nmol/L, specificity 71%, sensitivity 73%) and adrenal function (AUC = 0.861, optimal threshold 629 nmol/L, specificity 73%, sensitivity 100%).
Conclusions
The described protocol was efficient for more than 80% of patients. Using this protocol, the corticosteroid treatment interval is shorter than proposed in current guidelines.
Significance statement
A short but effective protocol for treatment of subacute thyroiditis with methylprednisolone is presented in this article. Using this protocol, the treatment interval is shorter than proposed in current guidelines. Its safety regarding possible adrenal insufficiency is assessed.

Glucagon-like peptide 1 receptor agonists (GLP-1RAs) have changed considerably the management of type 2 diabetes (T2D). However, recently published data from retrospective cohort studies suggest that chronic exposure to GLP-1RAs in T2D may increase the risk of papillary and medullary thyroid cancer. In this perspective, the role of the incretin system in thyroid carcinogenesis has been reviewed and critically commented on, aiming to understand if the time has arrived to be concerned about the risk. Although evidence suggested, speculative hypotheses should be verified, and further studies are urgently needed to clarify the issue.
