NCT ID: NCT03149354 Recruiting - HIV Infections Clinical Trials

Prevalence of Thyroid Function Abnormalities in HIV-infected Patients

THYVI
Start date: December 19, 2012
Phase: N/A
Study type: Interventional

Review the evolution of thyroid function in HIV-infected patients, with sufficient follow-up.

NCT ID: NCT03115515 Completed - Pregnancy Related Clinical Trials

Safety and Efficacy of Empiric Levothyroxine (LT4) Dose Increase Versus Individualized LT4 Dose Increase in Hypothyroid Women During Pregnancy

Start date: August 2011
Phase: N/A
Study type: Interventional

In women who require thyroid hormone replacement medication, the investigators will compare 2 ways to adjust thyroid medication during pregnancy to determine superiority in maintaining optimal blood levels of thyroid hormone. Thyroid hormone requirements increase significantly in pregnancy and it is important that blood levels of thyroid hormone remain normal so the fetus, which cannot make its own thyroid hormone has enough for early prenatal development. This trial compares 2 methods for adjusting thyroid medicine during pregnancy in women with known thyroid disease. Pregnant women (age 18 to 45) who take thyroid medication will be randomized to either 1) a 2-dose per week increase in thyroid medicine once pregnancy is confirmed, followed by dose adjustments every 2-4 weeks, or 2) adjustments in thyroid medication every 2-4 weeks in micrograms per day based on results of blood tests. The investigators will compare thyroid hormone levels throughout pregnancy between the groups of mothers to determine which method is superior in meeting the increased thyroid hormone requirements during pregnancy.

NCT ID: NCT03109847 Completed - Thyroid Clinical Trials

Metformin Hydrochloride in Mitigating Side Effects of Radioactive Iodine Treatment in Patients With Differentiated Thyroid Cancer

Start date: January 5, 2017
Phase: Phase 2
Study type: Interventional

This pilot clinical trial studies how will metformin hydrochloride works in mitigating the side effects of radioactive iodine treatment in patients with differentiated thyroid cancer. Metformin hydrochloride may reduce the metabolic activity of cancer cell and of surrounding supportive tissues.

NCT ID: NCT03093285 Recruiting - Thyroid Clinical Trials

Dysthyroidism and Female Sexual Function

Start date: January 2017
Phase:
Study type: Observational

The aim of the study is to evaluate the incidence of sexual dysfunction in presence of dysthyroidism and the impact of restoring euthyroidism on female sexual function

NCT ID: NCT03079193 Completed - Thyroid Clinical Trials

Post Thyroidectomy Endoscopic Laryngeal Examination :Is it Mandatory?

Start date: January 2011
Phase: N/A
Study type: Observational [Patient Registry]

Post thyroidectomy laryngeal nerve injuries are frequently encountered specially in total and near total thyroidectomy some unilateral injuries are not clinically evident and asymptomatic. The aim of this study is to compare mandatory versus selective post-thyroidectomy endoscopic examination of larynx to detect laryngeal nerve injuries.

NCT ID: NCT03060499 Withdrawn - Thyroid Clinical Trials

Post Thyroidectomy Myocardial Function

TECH
Start date: October 13, 2016
Phase:
Study type: Observational

Protocol Synopsis Protocol title: Post thyroidectomy myocardial function Purpose: Evaluation of the effects of total thyroidectomy on myocardial function Design: Prospective, single-center, cohort study Patient Population: Male or female subjects 18 years of age or older who are scheduled for total thyroidectomy No. of Subjects: 50 patients, estimated up to 12 months to enroll Duration of Treatment: Operation Duration of Follow-up: After discharge, the patients will be re-evaluated at three (3), six (6) and twelve (12) months in the outpatient clinic. Endpoints: To evaluate the changes in the myocardial function after the removal of the thyroid gland.

NCT ID: NCT03048708 Completed - Obesity Clinical Trials

Thyroid in Bariatric Surgery

ThyrBar
Start date: June 2011
Phase: N/A
Study type: Interventional

This study is expected to provide novel data regarding potential structural and functional changes of the thyroid gland in morbidly obese adults following significant weight loss through bariatric surgery. These data will complement evidence from epidemiological studies regarding the association of obesity and alterations in thyroid function. Potentially this study may justify further longer-term studies regarding the effects of weight gain and/or weight loss on the morphology of the thyroid gland and could help to form recommendations regarding follow-up investigations for the thyroid in morbidly obese patients.

NCT ID: NCT02943980 Completed - Thyroid Clinical Trials

Influenced the Type of Laryngoscopy the Intraoperative Nerve Monitoring During Thyroid Surgery

LiON
Start date: January 3, 2017
Phase: N/A
Study type: Interventional

A randomized controlled prospective study of laryngoscopy and evaluation of the Intraoperative nerve monitoring during thyroid surgery comparing direct laryngoscopy and the C-MAC videolaryngoscope.

NCT ID: NCT02912442 Not yet recruiting - Infertility Clinical Trials

Thyroid Autoimmunity and Reproductive Failure in Danish Women

Start date: December 2016
Phase: N/A
Study type: Observational

The present Ph.D.-study investigates the mechanisms behind the association between thyroid autoimmunity and reproductive failure.

NCT ID: NCT02776969 Recruiting - Thyroid Clinical Trials

A Gene Hunting Study for Familial Papillary Thyroid Cancer

Start date: August 5, 1998
Phase:
Study type: Observational

The aim of this project is to identify genetic risk factors associated with familial papillary thyroid carcinoma (PTC). Papillary thyroid cancer is a type of cancer that shows high heritability. However, the specific genetic factors that cause an increased risk have been elusive.
