Purpose: whole body scan (WBS) performed following diagnostic or therapeutic administration of I-131 is useful in patients with differentiated thyroid carcinoma. However, it can be falsely positive in various circumstances. We aimed to report a series of pitfalls in a clinical perspective.
Methods: A search in the database PubMed utilizing the following terms: "false radioiodine uptake" and "false positive iodine 131 scan" has been made in January 2023. Among the 346 studies screened, 230 were included in this review, with a total of 370 cases collected. Physiological uptakes were excluded. For each patient, sex, age, dose of I-131 administered, region and specific organ of uptake and cause of false uptake were evaluated.
Results: 370 cases of false radioiodine uptake were reported, 19.1% in the head-neck region, 34.2% in the chest, 14.8% in the abdomen, 20.8% in the pelvis, and 11.1% in the soft tissues and skeletal system. The origin of false radioiodine uptake was referred to non-tumoral diseases in 205/370 cases (55.1%), benign tumors in 108/370 cases (29.5%), malignant tumors in 25/370 cases (6.7%), and other causes in 32/370 cases (8.7%).
Conclusions: WBS is useful in the follow-up of patients with differentiated thyroid carcinoma, however it can be falsely positive in various circumstances. For this reason, it is critically important to correlate the scintigraphic result with patient's medical history, serum thyroglobulin levels, additional imaging studies and cytologic and/or histologic result.

Aim: To understand the association between macronutrient composition of a diet with Time in Range (TIR), Time above Range (TAR) and Time below Range (TBR) derived using a Continuous Glucose Monitoring (CGM) device for 14 days.
Methodology: An exploratory analysis on the baseline data of 50 Type 2 Diabetes Mellitus participants with age 25-55 years, HbA1c upto 8% and on Metformin only) enrolled for an interventional clinical trial was performed.
Results: Participants consuming adequate carbohydrates (CHO) of 55 to 60% of total calories had better Average Blood Glucose of 142.0 ± 24.0 mg/dL with a significance of p = 0.03 and Glucose Management Indicator (GMI) of 6.6 ± 0.7% significant at p = 0.01, than those with high CHO intake >60% of the total calories, with Average Blood Glucose - 155.0 ± 13.4 mg/dL and GMI - 7.06 ± 0.4%. Similarly, TIR - 68.2 ± 5.1% and TAR - 23.0 ± 10.8% was significantly better (p = 0.00) among those consuming adequate protein (12-15%) as compared to low protein (≤ 10%) with TIR- 61.0 ± 5.1% & TAR- 32.9 ± 10.3%. A correlation (r = -0.482 & p = 0.00) and simple linear regression analysis (R² = 0.33, F = 7.72, p = 0.000) revealed that when CHO intake increases the TIR decreases whereas TAR increases (r = 0.380 & p = 0.006). We did not find any significant relation between fat intake and TIR, TAR or TBR.
Conclusion: Our results suggest that lowering CHO, while increasing protein in the diet may help improve TIR. Further in-depth studies are needed to confirm these findings.

Purpose: Two-dimensional speckle tracking echocardiography is a novel ultrasound technique, which can detect early subclinical myocardial dysfunction with high sensitivity. The purpose of this study was to explore the value of speckle tracking echocardiography in the evaluation of subclinical myocardial injury in patients with Cushing's syndrome.
Methods: 35 patients with Cushing's syndrome and 29 healthy controls matched for age, sex, BMI, and systolic blood pressure were included in the study. All subjects were assessed using both conventional Doppler echocardiography and speckle tracking echocardiography. Among patients, they were further divided into inactive group (n = 7) and active group (n = 28) based on cortisol levels. Trend analysis was used among patients in different disease activity. Correlation analysis and linear regression analysis were used to explore influence factors related to subclinical myocardial dysfunction.
Results: Left ventricular ejection fraction value showed no statistical difference between patients Cushing's syndrome and control group. However, GLS and LVSD, show significant differences in Cushing's syndrome group. Also, among active Cushing's syndrome group, inactive Cushing's syndrome group and control group, GLS (-15.4 ± 3.0 vs -18.1 ± 3.1 vs-19.4 ± 2.4, P < 0001) and LVSD (48.9 ± 21.5 vs 43.5 ± 17.9 vs 28.5 ± 8.3, P < 0001) changed significantly with the disease activity status. In addition, GLS and LVSD were both linearly corrected with 24-hour urinary cortisol level.
Conclusion: GLS and LVSD are sensitive parameters in detecting and monitoring subclinical myocardial systolic dysfunction in patients with Cushing's syndrome. Myocardial injury is linearly correlated with cortisol level, which can be partially reversed after the biochemical control of cortisol.

Purpose: A potential association between breast (BC) and thyroid cancer (TC) has been observed. We investigated if the relationship between BC and TC is causal using bidirectional Mendelian randomization (MR) in Asian and European populations.
Methods: BC-linked single nucleotide polymorphisms (SNPs) were acquired from a genome-wide association study (GWAS) conducted by the Breast Cancer Association Consortium and Biobank Japan. The most recent TC GWAS data were obtained from the FinnGen Project and National Biobank of Korea. We assessed the potential causal relationship between BC and TC using various MR methods, including inverse-variance-weighting (IVW). Sensitivity, heterogeneity, and pleiotropic tests were performed to assess reliability.
Results: We found a bidirectional causal association between BC and TC within Europeans (IVW, TC on BC: odds ratio [OR] 1.090, 95% confidence interval [CI]: 1.012-1.173, P = 0.023; BC on TC: OR 1.265, 95% CI: 1.158-1.381, P < 0.001). A one-way causal relationship between BC susceptibility and TC risk was found in Asians (IVW BC on TC: OR 2.274, 95% CI: 2.089-2.475, P < 0.001). Subsequently, we identified a noteworthy bidirectional causal relationship between estrogen receptor (ER)-positive BC and TC (IVW, TC on ER-positive BC: OR 1.104, 95% CI: 1.001-1.212, P = 0.038; ER-positive BC on TC: OR 1.223, 95%CI: 1.072-1.395, P = 0.003), but not ER-negative BC and TC in Europeans.
Conclusion: We revealed a reciprocal causal association between ER-positive BC and TC. These findings establish a theoretical framework for the simultaneous surveillance and treatment of BC and TC.
目的:已观察到乳腺癌(BC)与甲状腺癌(TC)之间存在潜在关联。我们在亚洲和欧洲人群中使用双向孟德尔随机化(MR)方法研究了乳腺癌和甲状腺癌之间是否存在因果关系:方法:与 BC 相关的单核苷酸多态性(SNPs)来自乳腺癌协会联盟(Breast Cancer Association Consortium)和日本生物库(Biobank Japan)开展的全基因组关联研究(GWAS)。最新的 TC GWAS 数据来自芬兰基因项目(FinnGen Project)和韩国国家生物库(National Biobank of Korea)。我们使用各种 MR 方法(包括逆方差加权法(IVW))评估了 BC 与 TC 之间的潜在因果关系。为了评估可靠性,我们进行了敏感性、异质性和多向性测试:结果:我们发现欧洲人的 BC 与 TC 之间存在双向因果关系(IVW,TC 与 BC 的比值比 [OR] 1.090,95% 置信区间 [CI]:1.012-1.173):1.012-1.173, P = 0.023; BC on TC: OR 1.265, 95% CI: 1.158-1.381, P 结论:我们发现ER阳性BC与TC之间存在互为因果的关系。这些发现为同时监测和治疗 BC 和 TC 建立了一个理论框架。

Purpose: In the 9th edition of general rules for the description of thyroid cancer (GRDTC), the N factor was subdivided according to the maximum diameter of metastatic lymph nodes, presence of extra-nodal extension (ENE), and location of mediastinal lymph nodes. This study aimed to investigate the clinical usefulness of the 9th GRDTC risk stratification in papillary thyroid carcinoma (PTC) patients with lymph node metastasis.
Methods: A total of 703 PTC patients with lymph node metastasis who underwent initial thyroidectomy at our institution between January 2000 and October 2023 were included.
Results: Among the 703 patients with PTC, the 10-year cause specific survival rates of patients with pN1a-1 (n = 383), pN1a-2 (n = 13), pN1b-1 (n = 234), and pN1b-2 (n = 73) were 97.9%, 100%, 95.4%, and 76.2%, respectively (p < 0.001). Therefore, the pN1b-2 classification identified patients with a worse prognosis among those with pN1b. Among the 664 patients with M0 PTC, the 10-year disease free survival (DFS) rates of the patients with pN1a-1 (n = 378), pN1a-2 (n = 13), pN1b-1 (n = 215), and pN1b-2 (n = 58) were 86.9%, 62.5%, 79.9%, and 59.4%, respectively (p < 0.001). The pN1b-2 category was associated with worse DFS in pN1b patients.
Conclusions: The 9th edition of the GRDTC may be useful for stratifying the prognosis of patients with PTC. The risk assessment of PTC-related death and recurrence will be more accurate by considering the size of lymph node metastasis and ENE in GRDTC.

Purpose: Thyroid eye disease (TED) is the most common orbital disease in adults. Ocular motility restriction is the primary complaint of patients, while its evaluation is quite difficult. The present study aimed to introduce an artificial intelligence (AI) model based on orbital computed tomography (CT) images for ocular motility score.
Methods: A total of 410 sets of CT images and clinical data were obtained from the hospital. To build a triple classification predictive model for ocular motility score, multiple deep learning models were employed to extract features of images and clinical data. Subgroup analyses based on pertinent clinical features were performed to test the efficacy of models.
Results: The ResNet-34 network outperformed Alex-Net and VGG16-Net in prediction of ocular motility score, with the optimal accuracy (ACC) of 0.907, 0.870, and 0.890, respectively. Subgroup analyses indicated no significant difference in ACC between active or inactive phase, functional visual field diplopia or peripheral visual field diplopia (p > 0.05). However, in the gender subgroup, the prediction model performed more accurately in female patients than males (p = 0.02).
Conclusion: In conclusion, the AI model based on CT images and clinical data successfully realized automatic scoring of ocular motility in TED patients. This approach potentially enhanced the efficiency and accuracy of ocular motility evaluation, thus facilitating clinical application.

Background: The intricate interplay between the immune system and tumor plays a pivotal role in thyroid cancer (TC) pathogenesis, potentially influencing both the causation and therapeutic outcomes. Despite extensive research, existing literature offers ambiguous insights regarding the association between immune cell traits and thyroid cancer progression.
Methods: To elucidate the potential causal relationships, we conducted an integrated two-sample Mendelian randomization (MR) analysis. This study utilized publicly genetic datasets to explore the causalities between 731 immune cell traits (categorized into four trait types across seven panels) and thyroid cancer. We ensured the robustness of our findings through comprehensive sensitivity analyses, meticulously assessing potential sources of bias such as pleiotropy.
Results: After False Discovery Rate (FDR) correction, six immune cell traits were identified to be significantly associated with thyroid cancer risk (Inverse Variance Weighted, IVW): Absolute count of gamma delta T cells/ T-cell receptor gamma delta absolute count (TCRgd AC) 0.8464 (OR95% CI = 0.7477-0.9580, P = 0.0083, PFDR = 0.0103); CD8 on bright CD8 cells (CD8 on CD8br) 0.8867 (OR95% CI = 0.8159-0.9637, P = 0.0047, PFDR = 0.0093); CD127 on CD45RA negative CD4 T cells not regulatory T cells (CD127 on CD45RA- CD4 not Treg) 0.8969 (OR95% CI = 0.8192-0.9820, P = 0.0186, PFDR = 0.0186); CD80 on CD62L positive plasmacytoid dendritic cells (CD80 on CD62L+ plasmacytoid DC) 1.1091 (OR95% CI = 1.0267-1.1982, P = 0.0086, PFDR = 0.0103); CD80 on plasmacytoid DC 1.1283 (OR95% CI = 1.0462-1.2168, P = 0.0017, PFDR = 0.0093); Side scatter-area on bright CD8 cells (SSC - A on CD8br) 1.1622 (OR95% CI = 1.0507-1.2854, P = 0.0035, PFDR = 0.0093).
Conclusions: Our study demonstrated the causalities between immune cell traits and thyroid cancers by Mendelian randomization study, thus guiding future mechanism studies.

Background: Calcitonin is a sensitive marker for medullary thyroid carcinoma (MTC) diagnosis and postsurgical follow-up. This study aimed to define the gender and tumor size-specific calcitonin cutoff values for diagnosing MTC.
Methods: This retrospective study recruited 95 MTC patients and 10,523 non-MTC patients who underwent thyroid nodule surgery at Zhongshan Hospital between January 2015 and June 2023. Receiver operating characteristic (ROC) curves were used to assess calcitonin cutoff values for diagnosing MTC.
Results: Calcitonin levels in non-MTC patients were influenced by gender, CKD stage and age, with gender being the highest ranked predictor. In MTC patients, calcitonin levels were associated with tumor diameter, lymph node metastasis, and TNM stage. In the entire study population, calcitonin cutoff values to diagnose MTC were 17.75 pg/mL for males (sensitivity: 97.60%, specificity: 99.40%) and 7.15 pg/mL for females (sensitivity: 94.34%, specificity: 99.22%). In patients with a thyroid nodule diameter ≤10 mm, the calcitonin cutoff values to diagnose MTC were 17.50 pg/mL for males (sensitivity: 95.00%, specificity: 99.27%) and 7.15 pg/mL for females (sensitivity: 90.91%, specificity: 99.04%). In patients with a thyroid nodule diameter >10 mm, the calcitonin cutoff values to diagnose MTC were 104.80 pg/mL for males (sensitivity: 100.00%, specificity: 100.00%) and 32.60 pg/mL for females (sensitivity: 96.77%, specificity: 100.00%).
Conclusion: We have identified the gender and tumor size-specific cutoff values for the diagnosis of MTC. Cutoff values based on gender and tumor diameter may help to improve the accuracy of preoperative diagnosis of MTC, which is worth to be verified by future studies.

Purpose: To perform a molecular profiling of the metastases from papillary thyroid carcinomas (PTCs) and poorly differentiated thyroid carcinomas (PDTCs).
Methods: We retrieved and analyzed the molecular and clinical features of 136 metastases from PTCs and 35 metastases from PDTCs subjected to targeted DNA sequencing, from cBioPortal. The clinicopathological data included the number and location of the metastases, and genomic data included mutations, translocations, copy number alterations and fraction of the genome altered (FGA).
Results: Bone metastases from PTCs had a lower frequency of BRAF mutations than the lymph node metastases (LNMs) (43% vs 88%, p < 0.01), and a higher frequency of RBM10 and NRAS mutations than the LNMs (21% vs 3% for both, p < 0.05). The FGA of the bone metastases was higher than the FGA of the lung metastases (5.6% vs 1.3%, p < 0.05). The frequency of RET translocations was higher in the lung metastases from PTCs than the LNMs (15% vs 3%, p < 0.05). The LNMs from PTC patients harboring 4 or more distant metastases (DMs) had a higher frequency of TERT promoter mutations than the LNMs from patients harboring less than 4 DMs (96% vs 65%, p < 0.001). SDHA gene amplifications were enriched in the bone metastases from PDTCs and absent in the LNMs (38% vs 0%, p < 0.05).
Conclusion: Metastases from PTCs and PDTCs harbor clinically relevant alterations affecting distinct body locations, such as NRAS and RBM10 mutations, RET translocations and SDHA amplifications that may be explored therapeutically.
