A Brief Video Intervention to Improve Patient Outcomes Following Radioiodine Treatment

This study will test the impact of a short video intervention for people who are receiving radioiodine treatment for thyroid conditions (such as hyperthyroidism or thyroid cancer). After their single-dose treatment, patients need to follow safety instructions to protect others and manage side effects during recovery. Some people find these instructions hard to remember, and side effects (or anticipation of side effects) can feel worrying or disruptive. The video aims to present the treatment information in a more accessible patient-friendly way, so that patients feel less distressed, find their side effects easier to cope with, and better engage with safety precautions. All patients will first have a pre-treatment consultation with their doctor and receive the standard treatment information currently provided. Before this consultation patients will be randomly assigned to view one of two videos. The control group will see a neutral video that details standard health information that is not specific to radioiodine, while the intervention group will see a video that explains side effects, safety requirements and recovery period in a more adaptive way. Comparing these two groups will allow us to assess whether this new approach improves coping, reduces distress, and enhances adherence to safety instructions in the post-dose recovery phase of radioiodine treatment.

Impact of Vitamin D Therapy on Thyroid Function and Antibody Levels in Pediatric Graves' Disease

The goal of this randomized pilot feasibility clinical trial is to determine the feasibility of implementing a protocol for a larger trial to assess the effects of high-dose vitamin D supplementation in pediatric patients (9-17 years old) newly diagnosed with Graves' disease. The main questions it aims to answer are: What are the recruitment and adherence rates for a larger trial using this protocol? Is the data collection process complete and robust enough for a larger trial? What are the potential barriers to implementing a larger-scale trial? Researchers will compare vitamin D supplementation plus standard methimazole therapy to methimazole therapy alone (with participants permitted to take up to 1000 International Units of vitamin D2 daily) to explore potential effects on thyroid hormone and antibody levels. Participants will: Be randomized to either the intervention or control group. Take study medications (vitamin D or placebo) as directed. Attend regular study visits for blood tests and clinical assessments. Complete medication logs.

Hyperthyroidism as a Potential Predictive of Worse Outcome of Renal Graft

The objectives of the study are: to research the association, if any, between the occurrence of thyroid function changes in the immediate post-transplant period and the prognosis of the transplant itself; identify any risk factors for the occurrence of thyroid disorders In the immediate post-transplant period.

A Clinical Study of Hyperthyroidism in Children

This study intends to conduct a retrospective and prospective study on children with hyperthyroidism, and it is a non-intervention study to collect information on diagnosis and treatment and long-term follow-up of children with hyperthyroidism. To investigate the clinical characteristics, treatment effect, side effects and remission of hyperthyroidism in children, to analyze the predictive factors for the effect of antithyroid drug treatment, remission and recurrence after drug withdrawal, and to explore the risk factors related to the occurrence of antithyroid drug-related adverse reactions.

Iodine Supplementation in Graves' Hyperthyroidism

In China, the morbidity of thyroid diseases is high and the harm is serious. Iodine is closely related to thyroid diseases. It should be paid attention to guide patients to supplement iodine scientifically. Thyroid iodine uptake in hyperthyroidism patients is enhanced, and patients are generally advised to limit iodine intake in clinical practice. However, recent studies suggest that there is no definite conclusion on whether patients with hyperthyroidism should strictly limit iodine intake. The purpose of this study is to establish a national multi-center iodine intervention cohort for patients with Graves' hyperthyroidism, identify the effects of different iodine intake on hyperthyroidism, and establish iodine intervention program for hyperthyroidism. This study is a multicenter, prospective, open-level, randomized, controlled, parallel group clinical trial with a total sample size of 315 cases, a total of 3 participating units, each of which completed 105 cases. All subjects meeting the inclusion criteria were completely randomized in each center according to the random procedure with a probability of 1:1:1: ① Iodine Supplementation in Whole Course of Treatment with ATDs; ② Iodine Supplementation During Maintenance Treatment with ATDs; ③ Iodine Restriction in Whole Course of Treatment with ATDs. Information was collected before ATD treatment, at 3 months, 6 months, 12 months, 18 months (withdrawal), 6 months and 12 months after ATDs withdrawal. The primary purpose of this study is to analyze the difference in remission rate of hyperthyroidism between different iodine nutritional interventions. At the same time, the differences of duration from initiation to withdrawal of ATDs, duration from initiation of ATDs to thyroid function (including serum FT3, FT4 and TSH) normalization, duration from initiation of ATDs to serum FT3 and FT4 normalization, quality of life (QOL) in patients with Graves' hyperthyroidism, adverse effects rate of ATDs treatment, duration from initiation of ATDs to serum negative TRAb is first measured were observed.
