Filter by:The purpose of this experiment is to compared the changes of thyroid function, anti-thyroid peroxidase antibody, anti-thyroglobulin antibody, thyroid magnetic resonance T1-mapping and various metabolic indexes from baseline to the end of treatment (after the thyroid function had been normal for more than three months)
The purpose of this study is to test a liquid levothyroxine formula and examine if it will lead to improvement in management of thyroid function and if it improves hypothyroid symptoms that patients experience.
Reference intervals (RIs) of thyroid-stimulating hormone (TSH) and free thyroxine (FT4) are age, assay and population specific. Currently, the age and assay-specific RIs for TSH are not available for children under two years of age. This study aimed to establish reference intervals for serum concentrations of TSH and FT4 in healthy children aged 1-24 months as per CLSI C28-A3 guidelines.
Physiological changes necessitate the use of pregnancy-specific reference ranges for thyrotrophin (TSH) and free T4 (FT4) to diagnose thyroid dysfunction during pregnancy. Although many centers use fixed upper limits for TSH of 2.5 or 3.0 mU/L, this may lead to overdiagnosis or even overtreatment. The new guidelines of the American Thyroid Association have considerably changed recommendations regarding thyroid function reference ranges in pregnancy accordingly. Any hospital or physician that is still using the 2.5 or 3.0 mU/l cut-off for TSH during pregnancy should evaluate their own lab-specific cut-offs. The investigator's objective is to establish a rational reference range of serum TSH for the diagnosis of subclinical hypothyroidism in the first, second, and third trimester of pregnant women in the Sancaktepe region in Turkey.
Post-acute sequelae of SARS-CoV-2 infection can cause multiple system function disorders, and complicated symptoms last for an extended period. The virus can cause this continued infection, or the virus causes immune system function disorder and post-infectious autoimmune disease. The clinical symptoms can be smell loss, taste loss to liver function disorder, kidney function failure, different. No matter how complicated the systems showed in the clinic, all of the symptoms are due to the specific cells being damaged. Our clinical study is focused on recovering the damaged structure and function of the cells that could restore the organ function back to normal or close to normal
Aortic stenosis is highly prevalent in advancing age. The prognosis of this disease has dramatically changed with the surgical replacement of the aortic valve and the trans catheter aortic valve re-placement (TAVI). The TAVI procedure is also successful in octogenarians and frail patients. However, the evaluation before the TAVI procedure requires a high dosage of iodinated contrast agent with, consequently, an increased risk for thyroid dysfunction. The primary endpoint of this study is to assess, prospectively, the incidence and the predictive factors (underlying thyroid disease, medication, food preservative, topical antiseptics) of hypothyroidism after a TAVI procedure. The secondary endpoint is the influence of the occurrence of hypothyroidism after the TAVI procedure on the geriatric assessment.
This study is a single center observational study to investigate the association between biosignals from wearables and thyroid dysfunction.
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.
Type of Study Questionnaire- Development and validation Information about the Q'SHY: - The Q'SHY- Questionnaire for Screening of Hypothyroidism is a Patient Reported Outcome (PRO) tool to enable screening for Hypothyroidism in the general population. - It is a 20-item questionnaire which covers aspects of the symptoms of Hypothyroidism and incorporates the contributory factors from patient history which when combined, provides a robust tool to effectively screen the population. - The questionnaire content is being created based on a thorough search for relevant literature and encompasses all important aspects for screening purposes
The purpose of this research study is to measure the changes in energy metabolism (how the body burns energy), cardiovascular function (heart function), and lipid metabolism (cholesterol break down and building) before and after thyroidectomy (surgical removal of thyroid gland) in response to two approved therapies for hypothyroidism: levothyroxine (LT4) or Liothyronine/levothyroxine (LT3/LT4) combination therapy.
