Iodine Nutrition, Thyroid-stimulating Hormone, and Related Factors of Postpartum Women from three Different Areas in China: A Cross-sectional Survey

Objective Studies on the relationship between iodine,vitamin A(VA),and vitamin D(VD)and thyroid function are limited.This study aimed to analyze iodine and thyroid-stimulating hormone(TSH)status and their possible relationships with VA,VD,and other factors in postpartum women.Methods A total of 1,311 mothers(896 lactating and 415 non-lactating)from Hebei,Zhejiang,and Guangxi provinces were included in this study.The urinary iodine concentration(UIC),TSH,VA,and VD were measured.Results The median UIC of total and lactating participants were 142.00µg/L and 139.95µg/L,respectively.The median TSH,VA,and VD levels in all the participants were 1.89 mIU/L,0.44μg/mL,and 24.04 ng/mL,respectively.No differences in the UIC were found between lactating and non-lactating mothers.UIC and TSH levels were significantly different among the three provinces.The rural UIC was higher than the urban UIC.Obese mothers had a higher UIC and a higher prevalence of excessive TSH.Higher UICs and TSHs levels were observed in both the VD deficiency and insufficiency groups than in the VD-sufficient group.After adjustment,no linear correlation was observed between UIC and VA/VD.No interaction was found between vitamins A/D and UIC on TSH levels.Conclusion The mothers in the present study had no iodine deficiency.Region,area type,BMI,and VD may be related to the iodine status or TSH levels.

Effect of TSH Suppression Therapy on Sex Hormone Levels after Thyroid Cancer Surgery

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.

Analysis of the value and safety of thyroid-stimulating hormone in the clinical efficacy of patients with thyroid cancer

BACKGROUND Thyroid cancer(TC)is a common malignant tumor in the endocrine system.In recent years,the incidence and recurrence rates of TC have been raising due to increasing work pressure and irregular lifestyles.Thyroid-stimulating hormone(TSH)is a specific parameter for thyroid function screening.This study aims to explore the clinical value of TSH in regulating the progression of TC,so as to find a breakthrough for the early diagnosis and treatment of TC.AIM To explore the value and safety of TSH in the clinical efficacy of patients with TC.METHODS 75 patients with TC admitted to the Department of Thyroid and Breast Surgery of our hospital from September 2019 to September 2021 were selected as the observation group,and 50 healthy subjects were selected as the control group during the same period.The control group was treated with conventional thyroid replacement therapy,and the observation group was treated with TSH suppression therapy.The soluble interleukin(IL)-2 receptor(sIL-2R),IL-17,IL-35levels,free triiodothyronine(FT3),free tetraiodothyronine(FT4),CD3+,CD4+,CD8+,CD44V6,and tumor supplied group of factor(TSGF)levels were observed in the two groups.The occurrence of adverse reactions was compared between the two groups.RESULTS After treatment with different therapies,the levels of FT3,FT4,CD3+,and CD4+in the observation group and the control group were higher than those before treatment,while the levels of CD8+,CD44V6,and TSGF were lower than those before treatment,and the differences were statistically significant(P<0.05).More importantly,the levels of sIL-2R and IL-17 in the observation group were lower than those in the control group after 4 wk of treatment,while the levels of IL-35 were higher than those in the control group,and the differences were statistically significant(P<0.05).The levels of FT3,FT4,CD3+,and CD4+in the observation group were higher than those in the control group,and the levels of CD8+,CD44V6,and TSGF were lower than those in the control group.There was no significant difference in the overall incidence rate of adverse reactions between the two groups(P>0.05).CONCLUSION TSH suppression therapy can improve the immune function of patients with TC,lower the CD44V6 and TSGF levels,and improve serum FT3 and FT4 levels.It demonstrated excellent clinical efficacy and a good safety profile.

Correlation analysis of serum thyroglobulin,thyroid-stimulating hormone levels,and thyroid-cancer risk in thyroid nodule surgery

BACKGROUND Thyroglobulin(Tg)is one of the markers of thyroid cancer,and its concentration may be elevated in patients with malignant thyroid tumors.Thyroid-stimulating hormone(TSH)is secreted by the pituitary gland,which has a significant impact on thyroid gland function.Excessively high or low TSH levels may be associated with an increased risk of thyroid cancer.Thus,in-depth studies on the association of serum Tg and TSH levels with thyroid cancer risk in patients with thyroid nodules are warranted.This can help determine whether Tg and TSH levels can predict the degree of malignancy of thyroid nodules,which can in turn guide doctors in making accurate diagnoses and treatment decisions.Furthermore,such studies can provide more accurate diagnostic methods for thyroid nodules and help patients become aware of the presence of thyroid cancer as early as possible,thereby improving the success rate of treatment and prognosis.AIM To investigate the association of serum Tg and TSH levels with the risk of thyroid cancer in patients undergoing thyroid nodule surgery.METHODS The clinical data and laboratory examination results of 130 patients who underwent thyroid nodule surgery were retrospectively analyzed.Furthermore,their preoperative serum Tg and TSH levels were recorded.Histopathological examination conducted during follow-up revealed the presence of thyroid cancer.Correlation analysis were used to analyze the association of Tg and TSH levels with the risk of thyroid cancer.RESULTS Of the 130 patients,60 were diagnosed with thyroid cancer.Statistical analysis revealed a significant positive correlation between serum Tg levels and the risk of thyroid cancer(P<0.05).This suggests that high serum Tg levels are associated with an increased risk of thyroid cancer.However,no significant correlation was observed between serum TSH levels and the risk of thyroid cancer(P>0.05).CONCLUSION In patients who underwent thyroid nodule surgery,serum Tg levels exhibited a significant correlation with the risk of thyroid cancer but serum TSH levels did not.These findings suggest that serum Tg can serve as an important biomarker for assessing the risk of thyroid cancer in these patients.

Comprehensive treatment of thyroid-stimulating hormone(TSH)-secreting pituitary adenoma:one case report

Thyroid-stimulating hormone(TSH)-secreting pituitary adenoma is a rare type in all pituitary tumors.Recently we treated a TSH-secreting pituitary tumor in our hospital.The patient had been treated for hyperthyroidism,in which methimazole had been prescribed for 10 years,but the symptoms had not been alleviated.MRI imaging demonstrated the typical features of a sellar tumor,and the diameter was approximately 2.7 cm.Based on the laboratory studies:T3 at 6.27 nmol/L,T4 at 260.10 nmol/L,FT3 at 17.22 pmol/L,FT4 at 76.06 pmol/L,TSH at 9.93 Mu/L,the patient was diagnosed with a TSH-secreting pituitary tumor and central hyperthyroidism.After the patient was given octreotide for one week,he received resection of tumor via single-nostril transsphenoidal approach.After discharge,the patient received the radiation therapy two courses about 20 days.Through the comprehensive treatment of surgery,radiotherapy and drugs,the patient received a satisfactory result.

Thyroid-stimulating hormone-thyroid hormone signaling contributes to circadian regulation through repressing clock2/npas2 in zebrafish

Thyroid-stimulating hormone(TSH)is important for the thyroid gland,development,growth,and metabolism.Defects in TSH production or the thyrotrope cells within the pituitary gland cause congenital hypothyroidism(CH),resulting in growth retardation and neurocognitive impairment.While human TSH is known to display rhythmicity,the molecular mechanisms underlying the circadian regulation of TSH and the effects of TSH-thyroid hormone(TH)signaling on the circadian clock remain elusive.Here we show that TSH,thyroxine(T4),triiodothyronine(T3),and tshba display rhythmicity in both larval and adult zebrafish and tshba is regulated directly by the circadian clock via both E′-box and D-box.Zebrafish tshba^(−/−)mutants manifest congenital hypothyroidism,with the characteristics of low levels of T_(4)and T_(3)and growth retardation.Loss or overexpression of tshba alters the rhythmicity of locomotor activities and expression of core circadian clock genes and hypothalamic-pituitary-thyroid(HPT)axis-related genes.Furthermore,TSH-TH signaling regulates clock2/npas2 via the thyroid response element(TRE)in its promoter,and transcriptome analysis reveals extensive functions of Tshba in zebrafish.Together,our results demonstrate that zebrafish tshba is a direct target of the circadian clock and in turn plays critical roles in circadian regulation along with other functions.
