Purpose:The present work examines the associations of dietary habits,sedentarism,physical activity(PA)levels and sleep habits,with thyroid function in young euthyroid adults.Methods:A total of 105 young euthyroid adults participated in this cross-sectional study.Thyroid function was determined in fasting conditions(>6 h).Dietary habits were measured by a food frequency questionnaire and three non-consecutive 24 h recalls,and different dietary intake and patterns were then estimated.The time spent in sedentary,PA levels and sleep habits were objectively measured using a wrist-worn accelerometer.Results:Energy and carbohydrate intake were positively associated with thyroid stimulating hormone(TSH)(β=0.222;R^(2)=0.102;P=0.022 andβ=0.425;R^(2)=0.129;P=0.007,respectively)whereas fat intake was negatively associated with TSH(β=-0.428;R^(2)=0.137;P=0.004).Energy intake was also positively associated with free triiodothyronine(β=0.277;R^(2)=0.137;P=0.004).Further,adherence to the Mediterranean diet was negatively related to TSH and free thyroxine(FT4)(β=-0.221;R^(2)=0.113;P=0.020 andβ=-0.268;R^(2)=0.071;P=0.007,respectively).Vigorous-intensity and overall PA were negatively associated with FT4(β=-0.227;R^(2)=0.052;P=0.022 andβ=-0.204;R^(2)=0.042;P=0.041,respectively).In contrast,no associations were found between sleep parameters and thyroid function.Conclusions:Lifestyle factors such as dietary intake and PA levels seems to be related to thyroid function even in young euthyroid adults. 展开更多

BACKGROUND Patients rarely develop complicated infections in thyroid cysts.Here,we describe a patient with chronic infected unilateral giant thyroid cyst related to diabetes mellitus(DM).CASE SUMMARY A 66-year-old male was admitted due to an evident neck lump for 5 d after approximately 40 years of gradually progressive neck mass and 7 years of DM.Doppler ultrasound and computed tomography scan showed a giant lump in the left thyroid gland lobe.He was diagnosed with a large thyroid nodule complicated by tracheal dislocation and had surgical indications.Surgical exploration revealed evident inflammatory edema and exudation between the left anterior neck muscles,the nodule and glandular tissue.Fortunately,inflammatory lesions did not affect major neck vessels.Finally,a left partial thyroidectomy was performed.Macroscopic observation showed that the cystic thyroid mass consisted of extensive cystic wall calcification and was rich in massive rough sand-like calculi content and purulent matter.Postoperative pathology confirmed benign thyroid cyst with chronic infection.CONCLUSION The progression of this chronic infectious unilateral giant thyroid cyst may have been related to DM,and identifying blood vessels involvement can prevent serious complications during operation. 展开更多

Introduction: Since its creation in 2017 by the European community, the EU-TIRADS classification has enjoyed an excellent reputation in several countries around the world. Indeed, several studies conducted in these countries testify to the effectiveness of this tool for the management of nodular thyroid pathology. However, in Benin, the contribution of this classification has not yet been evaluated. It is therefore to overcome this inadequacy that we undertook this study. Objective: Participate in improving the diagnostic and therapeutic management of thyroid nodules at the CNHU HKM in Cotonou and at the CHUZ in Suru-Léré. Methods: This is a cross-sectional study with retrospective data collection spread over a period of 3 years 5 months, from January 2019 to May 2022 and carried out jointly in the Endocrinology Metabolism Nutrition and ORL-CCF departments of the CNHU HKM of Cotonou and in the ORL-CCF department of the CHUZ of Suru-Léré. The study population consisted of patients who consulted the University Clinic of Endocrinology Metabolism Nutrition, the University Clinic of ORL-CCF of the CNHU-HKM and the University Clinic of ORL-CCF of the CHUZ of Suru-Léré for thyroid nodule and who have had surgery. The study data was collected from patients hospitalization records using a survey form. Results: On ultrasound, according to the EU-TIRADS classification, 56.8% of nodules presented a low risk of malignancy (EU-TIRADS 3) compared to respectively 19.8%;23% and 2.5% of nodules with zero (EU-TIRADS 2), intermediate (EU-TIRADS 4) and high (EU-TIRADS 5) risk of malignancy. Regarding the performance of this classification, it is sensitive in 37.5% of cases and has a specificity of 78.5% with a PPV (Positive Predictive Value) and a NPV (Negative Predictive Value) respectively of 6.6 % and 91.6%. Furthermore, the bivariate correlations revealed that the size of the nodule was significantly associated with the malignancy of the nodule (p = 0.014) and the calculated value of the Yule’s Q coefficient (0.375) reflects a moderate intensity of the connection between the EU-TIRADS and histology. Conclusion: the EU-TIRADS classification, due to its excellent NPV, is of great interest for the management of thyroid nodules at the CNHU-HKM of Cotonou and at the CHUZ of Suru-Léré. In view of this, particular emphasis must be placed on its regular and rigorous use. 展开更多

BACKGROUND A fish spike stuck in the throat is a common ear,nose,and throat(ENT)emergency.However,it is very rare for a fish spike to reach the thyroid tissue through the throat,which is very dangerous and can lead to pharyngeal fistula,cervical abscess,mediastinal abscess,and thyroid abscess.Proper and timely management can help reduce complications,especially in elderly patients.CASE SUMMARY In the case presented here,the causative factor was dentures,but improper management aggravated the condition.In the case presented here,an elderly woman with a history of accidentally swallowing fish bones for 20 d had a sensation of foreign bodies in her throat.Eventually,computed tomography(CT)of the neck showed that the left side of the thyroid gland had a dense shadow in the form of a stripe.CONCLUSION If a fishbone foreign body is not visible during endoscopic examination but the patient has significant symptoms,the surgeon should be aware that the fishbone may be lodged in the thyroid.To avoid a misdiagnosis,ultrasound,CT,and other tests can be used to clarify the diagnosis.T The first step in treating a fish bone in the thyroid gland is to determine the position of the foreign body and the extent of the infection,and to develop a personalized surgical plan for its removal.At the same time,scientific information should be made available to the general public so that people know that if a fish bone is accidentally lodged,they should not force it to be swallowed or be spit out by inducing vomiting,which are incorrect methods and may aggravate the condition or even cause it to migrate outside the cavity,leading to serious complications,as in this reported case. 展开更多

As a common hyperglycemic disease,type 1 diabetes mellitus(T1DM)is a complicated disorder that requires a lifelong insulin supply due to the immunemediated destruction of pancreaticβcells.Although it is an organ-specific autoimmune disorder,T1DM is often associated with multiple other autoimmune disorders.The most prevalent concomitant autoimmune disorder occurring in T1DM is autoimmune thyroid disease(AITD),which mainly exhibits two extremes of phenotypes:hyperthyroidism[Graves'disease(GD)]and hypothyroidism[Hashimoto's thyroiditis,(HT)].However,the presence of comorbid AITD may negatively affect metabolic management in T1DM patients and thereby may increase the risk for potential diabetes-related complications.Thus,routine screening of thyroid function has been recommended when T1DM is diagnosed.Here,first,we summarize current knowledge regarding the etiology and pathogenesis mechanisms of both diseases.Subsequently,an updated review of the association between T1DM and AITD is offered.Finally,we provide a relatively detailed review focusing on the application of thyroid ultrasonography in diagnosing and managing HT and GD,suggesting its critical role in the timely and accurate diagnosis of AITD in T1DM. 展开更多

BACKGROUND In recent years,the emergence of multiplex technology that can simultaneously measure multiple anti-islet autoantibodies has become particularly valuable for the staging and early diagnosis of immune-mediated type 1 diabetes(T1D).While it has been established that 20%-30%of T1D patients suffer from autoimmune thyroid disease(AITD),there is limited available data regarding the presence of anti-islet autoantibodies in AITD patients.Among commercially available anti-islet autoantibodies,glutamic acid decarboxylase 65 autoantibodies(GADAs)are often the first marker measured in general clinical practice.AIM To investigate the frequency of anti-islet autoantibodies in AITD patients.METHODS Our study involved four hundred ninety-five AITD patients,categorized into three distinct groups:AITD with T1D(n=18),AITD with phenotypic type 2 diabetes(T2D)(n=81),and AITD without diabetes(n=396),and the enzyme-linked immunosorbent assay(ELISA)was employed to determine the frequencies of 3 Screen Islet Cell Autoantibody(3 Screen ICA),GADA,insulinoma-associated antigen-2 autoantibodies(IA-2As),and zinc transporter 8 autoantibodies(ZnT8As)within these groups.RESULTS The frequency of 3 Screen ICA in AITD patients with T1D,T2D,and those without diabetes were 88.9%,6.2%,and 5.1%,respectively,with no significant difference seen between the latter two groups.Notably,the frequency of 3 Screen ICA was 11.1%higher in AITD patients with T1D,1.3%higher in AITD patients with T2D,and 1.1%higher in AITD patients without diabetes compared to GADA,respectively.Furthermore,12.5%,20.0%,and 20.0%of the 3 Screen ICA-positive patients were negative for GADA.Additionally,1.3%of the AITD patients who tested negative for 3 Screen ICA in both the AITD with T2D and non-diabetic AITD groups were found to be positive for individual autoantibodies.Among the 3 Screen ICA-positive patients,there was a significantly higher proportion of individuals with multiple autoantibodies in AITD patients with T1D compared to those without diabetes(37.5%vs 5.0%,P<0.05).However,this proportion was similar to that in AITD patients with T2D(20.0%).Nevertheless,there was no significant difference in 3 Screen ICA titers between AITD patients with T1D and those without diabetes(436.8±66.4 vs 308.1±66.4 index).Additionally,no significant difference in 3 Screen ICA titers was observed between Graves’disease and Hashimoto’s thyroiditis in any of the groups.CONCLUSION Our findings reveal that some AITD patients without diabetes exhibit 3 Screen ICA titers comparable to those in AITD patients with T1D.Thus,3 Screen ICA outperforms GADA in identifying latent anti-islet autoantibody-positive individuals among AITD patients. 展开更多

BACKGROUND The occurrence of thyroid cancer(TC)has increased in recent decades.Exposure to outdoor artificial light at night(ALN)is associated with an increased risk of cancer.AIM To investigated the impact of ALN,as a significant environmental pollutant,on TC incidence worldwide.METHODS The assessment involved analyzing satellite ALN data in conjunction with TC incidence data[adjusted standardized rate(ASR)],while considering the quality of cancer registries(QCR),gross domestic product(GDP)per person,and health expenditure per person(HEP)for each country.RESULTS Results indicated a correlation between higher ASR and ALN exposure percentages,particularly in countries with higher GDP or HEP quartiles(all P<0.05).Significant differences in ASR were observed across QCR levels,both high and low quality(all P<0.05),but not in countries without registry activity.However,when evaluating ASR against ALN exposure percentages while considering GDP/HEP quartiles or QCR levels,no significant associations were found(all P>0.10).CONCLUSION The findings suggest a potential link between higher GDP and adverse health conditions,serving as possible risk factors for TC,rather than a direct association with ALN.Limitations include the use of cross-sectional data,temporal misalign ment,and reliance on ALN as a socioeconomic proxy.It is proposed that light pollution might be connected to a lifestyle conducive to carcinogenesis.Additionally,the presence of higher GDP/HEP could enhance access to diagnostic resources,potentially facilitating TC diagnosis and inclusion in cancer registries. 展开更多

BACKGROUND Diabetes and thyroiditis are closely related.They occur in combination and cause significant damage to the body.There is no clear treatment for type-2 diabetes mellitus(T2DM)with Hashimoto's thyroiditis(HT).While single symptomatic drug treatment of the two diseases is less effective,combined drug treatment may improve efficacy.AIM To investigate the effect of a combination of vitamin D,selenium,and hypoglycemic agents in T2DM with HT.METHODS This retrospective study included 150 patients with T2DM and HT treated at The Central Hospital of Shaoyang from March 2020 to February 2023.Fifty patients were assigned to the control group,test group A,and test group B according to different treatment methods.The control group received low-iodine diet guidance and hypoglycemic drug treatment.Test group A received the control treatment plus vitamin D treatment.Test group B received the group A treatment plus selenium.Blood levels of markers of thyroid function[free T3(FT3),thyroid stimulating hormone(TSH),free T4(FT4)],autoantibodies[thyroid peroxidase antibody(TPOAB)and thyroid globulin antibody(TGAB)],blood lipid index[low-density lipoprotein cholesterol(LDL-C),total cholesterol(TC),triacylglycerol(TG)],blood glucose index[fasting blood glucose(FBG),and hemoglobin A1c(HbA1c)]were measured pre-treatment and 3 and 6 months after treatment.The relationships between serum 25-hydroxyvitamin D3[25(OH)D3]level and each of these indices were analyzed.RESULTS The levels of 25(OH)D3,FT3,FT4,and LDL-C increased in the order of the control group,test group A,and test group B(all P<0.05).The TPOAB,TGAB,TC,TG,FBG,HbA1c,and TSH levels increased in the order of test groups B,A,and the control group(all P<0.05).All the above indices were compared after 3 and 6 months of treatment.Pre-treatment,there was no divergence in serum 25(OH)D3 level,thyroid function-related indexes,autoantibodies level,blood glucose,and blood lipid index between the control group,test groups A and B(all P>0.05).The 25(OH)D3 levels in test groups A and B were negatively correlated with FT4 and TGAB(all P<0.05).CONCLUSION The combination drug treatment for T2DM with HT significantly improved thyroid function,autoantibody,and blood glucose and lipid levels. 展开更多

This research concentrates to model an efficient thyroid prediction approach,which is considered a baseline for significant problems faced by the women community.The major research problem is the lack of automated model to attain earlier prediction.Some existing model fails to give better prediction accuracy.Here,a novel clinical decision support system is framed to make the proper decision during a time of complexity.Multiple stages are followed in the proposed framework,which plays a substantial role in thyroid prediction.These steps include i)data acquisition,ii)outlier prediction,and iii)multi-stage weight-based ensemble learning process(MS-WEL).The weighted analysis of the base classifier and other classifier models helps bridge the gap encountered in one single classifier model.Various classifiers aremerged to handle the issues identified in others and intend to enhance the prediction rate.The proposed model provides superior outcomes and gives good quality prediction rate.The simulation is done in the MATLAB 2020a environment and establishes a better trade-off than various existing approaches.The model gives a prediction accuracy of 97.28%accuracy compared to other models and shows a better trade than others. 展开更多

Background: Thyroid diseases are among the leading endocrine disorders affecting a large proportion of people worldwide and show geographical variation in incidence and histopathological pattern related to age, sex, dietary and environmental factors. Histopathological patterns of surgically treated thyroid diseases play an important role in early diagnosis and management of these diseases. There is, however, limited published data regarding histopathological reports on thyroid disease in our local setting. This study aimed to determine the histopathological patterns and highlight early postoperative complications among patients with surgically treated thyroid diseases at Bugando Medical Centre (BMC). Methods: This was a longitudinal study involving all patients with surgically treated thyroid diseases seen at BMC over a period of 6 months from October 2019 to March 2020. Results: A total of 84 patients were studied. Females outnumbered males by a female to male ratio of 11:1. The median age of patients was 44 [IQR, 35 - 54] years old, the youngest was 14 years old and the oldest was 76 years old. Colloid goiter was the most common non-neoplastic lesion accounting for 34 (44.7%) patients. Among the neoplastic lesions, follicular adenoma was the most commonly encountered benign pathologies (n = 16;21.1%), while papillary carcinoma was the most commonly encountered malignancy (n = 4;50%). Following thyroidectomy, 12 (14.3%) patients developed early complications, of which hemorrhage sometimes requiring blood transfusion was the leading intra/postoperative complications accounting for 4 (33.3%) patients. Other complications include temporary recurrent laryngeal nerve palsy 2 (16.7%), surgical site infection 2 (16.7%) and tracheomalacia, bronchospasm, thyroid abscess and respiratory obstruction in 1 (8.3%) patient each, respectively. In this study, malignant thyroid lesion (p Conclusion: This study demonstrated that colloid goiter was the most common non-neoplastic lesion, and on the neoplastic category, follicular adenoma was the most common benign lesion, while papillary carcinoma was the most frequent malignant lesion. 展开更多

Background: Thyroid cancer is a rare disease yet the most common endocrine malignancy in pediatrics. Unlike adult patients, children with thyroid nodules typically don’t complain of pain, soreness, or difficulty swallowing. Additionally, using the recommended therapy for adults to treat paediatrics is not appropriate. There is an unmet need for updated unique guidelines for the management of papillary thyroid carcinoma (PTC) in paediatrics and adolescents. Case Report: A 12-year-old girl had an atypical presentation of metastatic PTC in lymph nodes. She was treated initially with hemi-thyroidectomy, followed by total thyroidectomy. A multidisciplinary team followed her up till successful results were found. Conclusion: Due to the difference in pathophysiology between thyroid tumors in children and adults, a unique approach to PTC management is to be implemented. Further trials are required for a better understanding of risk factors, the likelihood of recurrence, and the long-term side effects of the chosen management plan. 展开更多

Objective:To investigate the effect of TSH inhibition therapy in the postoperative management of patients with differentiated thyroid cancer.Methods:Seventy patients diagnosed with differentiated thyroid cancer were selected for the study.TSH inhibition therapy was administered to the research group,while thyroxine replacement therapy was provided to the control group during the postoperative management phase.This allowed for a comparative analysis between the two groups.Results:In comparison with the control group,the research group exhibited significant decreases in serum TSH,T3,and T4 levels after treatment,while FT4 and FT3 levels significantly increased(P<0.05).Additionally,significant decreases in Tg,VEGF,TSGF,CD44V6,and sIL-2R levels were observed in the research group after treatment(P<0.05).No significant differences were found in pre-treatment thyroid function between the two groups(P>0.05).Conclusion:The application of TSH inhibition therapy in the postoperative management of patients with differentiated thyroid cancer demonstrates promising outcomes. 展开更多

Objective:To analyze the effect of thyroid-stimulating hormone(TSH)suppression therapy on sex hormone levels in patients undergoing postoperative treatment for thyroid cancer.Methods:A total of 40 patients undergoing postoperative thyroid cancer treatment were selected for data analysis.TSH suppression therapy was implemented during the postoperative period.Patients were grouped according to the TSH level:TSH<0.1,0.1≤TSH<0.5,and TSH≥0.5.Results:Among male patients,there were no significant differences in sex hormone levels at different dosing times and TSH levels(P>0.05).For female patients,testosterone levels at different dosing times showed no significant differences under the same circumstances(P>0.05).The comparison of testosterone levels at different TSH levels over 5 years of TSH suppression therapy did not yield significant differences(P>0.05).However,the comparison of testosterone levels within 5 years of TSH suppression therapy yielded significant differences(P<0.05),with the lowest levels observed at 0.1≤TSH<0.5.Conclusion:The use of TSH suppression therapy in postoperative thyroid cancer treatment minimally affects sex hormone levels in male patients.However,it has a significant impact on female patients.Therefore,preoperative sex hormone testing is recommended,and postoperative monitoring should include regular sex hormone testing. 展开更多
