Hypothyroidism, Metabolism and Quality of Life - Focus on QOL, REE, Cognitive Function and Body...

Hypothyroidism

This project has the following primary aims: The main objective is to delineate the association between changes in Resting energy expenditure (REE) and QOL in hypothyroid patients before and after one year of L-T4 treatment. To achieve this, the investigators plan to compare newly diagnosed hypothyroid patients soon after diagnosis before L-T4 therapy has been initiated after 6 months and after 1 year of treatment. Primary endpoint is changes in REE compared to changes in QOL Secondary endpoint is changes in cognitive function and changes in body composition before and after one year of treatment and furthermore changes in insulin resistance following changes in body composition and free fatty acids (FFA).

Color Flow Doppler Ultrasound in Subclinical Thyroid Dysfunction

Subclinical HypothyroidismHyperthyroidism1 more

Overt hyperthyroidism and hypothyroidism are associated with inverted hemodynamic changes.Regional blood flow disturbances (including intrathyroidal) were also reported in these thyroid disorders. The purpose of this study is to investigate the thyroid vascularity and blood flow by Color Flow Doppler Sonography in patients with subclinical thyroid dysfunction

The Impact of Subclinical Hypothyroidism on Cardiovascular System

Hypothyroidism

This research aims to evaluate the relation between SCH and cardiovascular System by assessment of lipid profile and carotid intima-media thickness (CIMT), as a marker of atherosclerosis, and endothelial function.

ThyrOp: A Study of Individual Subclinical Hypothyroidism After Hemithyroidectomy for Benign Nontoxic...

GoiterHypothyroidism1 more

The hypothesis of the study is that among patients that do not develop overt hypothyroidism after hemithyroidectomy, weight gain is a clinical manifestation of a postoperatively lowered set point of thyroid function - even if the thyroid function is lowered within the laboratory reference range. The investigators refer to this hypothesized condition as individual subclinical hypothyroidism. Thyroid hormones are major regulators of mitochondrial function and subclinical hypothyroidism affects mitochondrial activity. The aim of the study is to examine if a lowered set point of thyroid function after hemithyroidectomy can be measured in the mitochondrial function, the body weight and the basal oxygen consumption.

Effects of Thyroid Hormone Withdrawal on Metabolic Parameters During Radioactive Iodine Therapy...

Hypothyroidism

The incidence of differentiated thyroid cancer is increasing in Korea. A significant number of them experience severe hypothyroidism in preparation for radioactive iodine (RAI) therapy after total thyroidectomy. Because the function of thyroid hormone is closely linked with lipid and glucose metabolism, overt hypothyroidism after thyroid hormone withdrawal during RAI therapy may induce the changes of metabolic parameters. We investigate the effects of thyroid hormone withdrawal on metabolic and cardiovascular parameters during radioactive iodine therapy in differentiated thyroid cancer.

Correlation Between Thyroid Function and Quality of Life in Hypothyroidism

Hypothyroidism

According to the prevalence survey of thyroid diseases in ten cities in China in 2010, TSH>4.2 mIU /L was the diagnostic cut-off point, and the prevalence of hypothyroidism was 17.8%, including 1.1% clinical hypothyroidism.The annual incidence of hypothyroidism in China is 2.9‰, and primary hypothyroidism is the most common.Typical patients have chilliness, fatigue, swelling of hands and feet, lethargy, memory loss, hypoperspiration, joint pain, weight gain, constipation, menstrual disorder or menorrhagia, infertility, which affects the physiological and psychological functions of patients and reduces the quality of life of patients.The treatment goal of primary clinical hypothyroidism is that the symptoms and signs of hypothyroidism disappear, and TSH, TT4 and FT4 values remain in the normal range.Levothyroxine (L-T4) is the main alternative therapy for this disease.Thyroid disease patients quality of life questionnaire (Thyroid - specific Patient Reported Outcome, ThyPRO) for the development of the Danish scholars such as WATT first can be applied to various comprehensive scale of benign Thyroid disease patients, applied in the Danish people has good reliability and validity, has been translated into ten languages application in many countries the crowd, WATT et al in 2015 developed the scale of the concise version (ThyPRO39).Studies have shown that in the treatment of patients with thyroid disease, even if thyroid function is within the normal range, there are still physiological or psychological impairments such as chills, fatigue, anxiety, depression, which reduces the quality of life of patients.Studies have shown that TSH level in patients with hypothyroidism is correlated with patients' quality of life. Even within the normal range, the higher TSH level is, the worse the patients' quality of life score is, and there is an independent correlation in fatigue and emotional susceptibility. This study except for other factors, such as merger disease with primary hypothyroidism patients quality of life assessment, observe the normal JiaJian patients, we use the current widely used thyroid disease patients to evaluate the quality of life questionnaire (ThyPRO - 39), observe thyroid hormone levels in patients with hypothyroidism and their quality of life scale and the relevance of the blood sugar, blood lipid metabolic indicators related to relevance.

NOMOTHETICOS: Nonlinear Modelling of Thyroid Hormones' Effect on Thyrotropin Incretion in Confirmed...

HypothyroidismHyperthyroidism

The NOMOTHETICOS study is a unicentric cross-sectional study for a quantitative analysis of feedback-inhibition in the thyrotropic homeostatic control. Structural parameters are obtained in vivo from open-loop analysis in patients with disconnected feedback, i.e. with overt thyroid dysfunction or full dose substitution therapy with levothyroxine.
