Active clinical trials for "Thyroid Diseases"

Persistent organic pollutants (POPs) are a class of organic pollutants in the environment characterized by persistent, bioaccumulation, long-range transport and biological toxicity. Due to its widespread distribution in the environment and Lipophilicity, POPs can bioaccumulate along the food chain and eventually accumulate in the human body. There are many types of POPs, including dioxins, polychlorinated biphenyls (PCBs) , polybrominated diphenyl ethers (PBDEs) and organochlorine pesticides (OCPs) . POPs is ubiquitous and Lipophilic in the environment, so the potential harm of POPs to human body has aroused wide concern. A growing number of studies have found that exposure to POPs may be associated with an increased risk of endocrine disease, particularly type 2 diabetes and thyroid cancer. The aim of this study was to assess the effect of Persistent organic pollutant exposure on the development ofType 2 diabetes and thyroid cancer by analyzing serum Persistent organic pollutant concentrations in controls, and patients with Type 2 diabetes and thyroid cancer.

The aim of the study is to measure urinary milk iodine concentration (MIC), iodine concentration (UIC), thyroid hormones (TSH, FT4) and thyroperoxidase antibodies (TPOab) in breast-feeding women, and UIC in their nursing infants to determine if the levels are adequate, and to see how they can be influenced by 150 ug daily iodine supplementation in breast-feeding women. The hypothesis is that there is a relative iodine deficiency in this sub-population - lactating women and nursing children-, and that this can be influenced by iodine supplementation. Adequate thyroid hormone and iodine levels are very important for small children, when the plasticity of the brain is greatest. This is as a prospective, double-blind, placebo-controlled study of 221 mothers and their infants. In parallel, 90 age-matched healthy non-pregnant women are recruited. Mothers are randomized to 150 µg/day iodide supplementation or placebo. Pregnant women are asked for participation on a visit in pregnancy week 37, at the mother health care (MVC) at Mölnlycke and Skövde. The study will run for approximately 3 months for each individual and begins by sampling A (UIC, TSH, FT4, TPOab) at week 37 of the pregnancy, when mothers also get randomized to 150 µg iodine or placebo. New sampling B (UIC, TSH, FT4, MIC ) is collected when the baby is 3 months old. Thereafter the study is completed. In parallel, 90 healthy non-pregnant, non-lactating women in the same age range are recruited and followed with UIC, TSH, FT4, TPOab for 6 months as a control group. In each case a simple questionnaire is filled and blood is also frozen for future analyses.

This study investigated the changes in serum thyroid function and urinary iodine levels before and after the use of iodinated contrast to analyze the prevalence of thyroid dysfunction in the Chinese euthyroid adults after using iodinated contrast.

The evaluation of carotid intima-media thickness (cIMT) has become a possible predictor of the future risk of cardiovascular diseases (CVD). Evidence to date shows that cIMT augmentation is correlated with the extent of atherosclerosis in the coronary arteries and with other risk factors for CVD. More recently, several studies have evaluated the association of cIMT with stroke, to determine whether this measure can also predict future cardiovascular events. Although the published evidence is scarce and fragmentary, the cIMT retains an increasingly interesting role as a marker of atherosclerotic pathology. The purpose of the study is to analyze cIMT in patients undergoing thyroidectomy to evaluate a possible correlation between the cIMT variation after the procedure and the cause of the thyroid disease, the levels of thyroid hormones, and the lipid or other markers of atherosclerosis levels. The primary endpoint will be the variation of the measure of the cIMT before and after surgery. Secondary endpoints will be: major cardiovascular adverse events (death, major stroke, minor stroke, transient ischemic attack) in the short-term period (≤30 days after the procedure); major cardiovascular adverse events (death, major stroke, minor stroke, transient ischemic attack) in the long-term period (>30 days after the procedure); the technical success of the procedure; the rate of postoperative complications. To date, there are no data that differentiate patients based on the causes of thyroid disease. The results of the present study will allow for correlating the variation of the cIMT to the causes of thyroid disease, the levels of thyroid hormones, and the levels of lipid and other markers of atherosclerosis. Results from the present study may provide insights into possible areas of quality improvement. It may also influence the economic impact associated with carotid revascularization techniques, in terms of hospital charges and discharges to skilled nursing and rehabilitation facilities.

the relationship between human exposure to EDCS and TC is poorly investigated and still unclear. The aim of this study is to evaluate the possible role of old and new generation endocrine disruptors in thyroid cancer. The primary aim is to evaluate the difference in the average levels of the main endocrine disruptors (PFAS, including: PFOA, PFOS, PFDA, PFUnA, PFHpS and possibly subsequently other categories, such as bisphenols, phthalates, parabens, PCBs, flame retardants) between patients with and without a diagnosis of thyroid cancer through highly sensitive, selective and precise mass spectrometry methods, such as liquid chromatography combined with tandem mass spectrometry (LC-MS / MS). The secondary aim is to evaluate the relationship between the concentrations of endocrine disruptors and some anamnestic variables studied (for example the type of diet, the use of personal care products).

This window of opportunity trial is studying a checkpoint inhibitor agent to treat differentiated thyroid cancer in a neoadjuvant setting. A checkpoint inhibitor is a compound aimed at restoring tumor immunosurveillance. The name of this agent is pembrolizumab.

Although most thyroid cancers are treated and cured successfully there are still 30% who recur after many years. This will eventually progress and at this point may become incurable with treatment options including complex and high risk surgery. The overall efficacy of systemic treatment in advanced thyroid cancer has a good initial response in most patients but not all. The treatment decisions are based on relying on radiological parameters such as using the RECIST criteria and measuring the rise in certain serum tumour biomarkers. However, the disadvantage of this is that this method can take many months to detect a change in disease volume. An improved understanding of genetics and cancer and potential gene sequencing can help achieve personalised treatment for patients. However, there are many questions and issues that still need to be answered and require urgent attention before being able to achieve optimate patient stratification. We need to identify better tumour biomarkers to detect disease progression, show real time response to treatment and understand why tumours evolve to becoming more aggressive. This study hopes to address these issues by proposing a multicentre prospective study to investigate the presence and role of ctDNA in advanced thyroid cancer including differentiated thyroid cancer , medullary thyroid cancer and Anaplastic Thyroid Cancer. The study will collect tissues and blood samples for various protein analysis, nucleic acid extraction and live cell analysis in order to try and detect the presence of plasma ctDNA at baseline of eligible patients.

This is a 2-cohort (observational and treatment cohort) extension study for participants completing feeder studies (IMVT-1401-3201 or IMVT-1401-3202). The observational cohort will assess the durability of proptosis response of feeder studies off treatment. The treatment cohort will evaluate the efficacy of batoclimab as assessed by proptosis responder rate.

DBS (Dried blood spot) is the collection of a small volume of blood on paper cards and subsequent transport to an analytical laboratory. This method is widely used for newborn screening programs around the world to identify inborn errors of metabolism where early diagnosis and treatment can be lifesaving. The World Health Organization and World Anti-Doping Agency (WADA) have independently endorsed DBS as an alternative to conventional testing methods due to its lessened invasiveness, lower collection and transport cost, reduction in sample storage needs, and for some analytes, improved sample stability. There are hundreds of publications describing DBS testing and some commercial ventures offering direct-to-consumer testing using DBS. However, it is not clear if there have been concerted efforts to develop DBS sampling for adults for home collection in concert with high quality, accredited central clinical laboratories. The proposal herein is focused on developing and validating DBS for at home and remote sample collections for routine diagnostic testing.

The purpose of this observational chart review study is to evaluate the efficacy and safety of Radiofrequency Ablation (RFA) for treatment of indeterminate thyroid nodules before and after RFA procedure. This is a data collection study in which the investigators ask patients to give access to information generated before and after RFA treatment of their condition. The RFA procedure uses image guidance to place an electrode through the skin into the target area. In RFA, high-frequency electrical currents are passed through an electrode, creating a small region of heat to treat the lesion.
