THYROID AND PREGNANCY
Mild abnormalities in thyroid hormone levels in one blood test in early pregnancy may become normal when repeated.
Thyroid hormone levels in pregnant women change during pregnancy. Most of the time, these changes are short-lived and resolve without therapy, but some do need to be treated. This study investigated how often the diagnosis of thyroid problems remains the same when thyroid hormone levels in pregnant women were checked more than once during early pregnancy.

Eye surgery for thyroid eye disease and quality of life
Symptoms of thyroid eye disease can be severe and affect quality of life in many ways. Treatment options are limited and surgery may be needed. This study was done by reviewing and analyzing existing studies to help assess whether the different types of eye surgery improved the quality of life in patients with thyroid eye disease.

Rituximab may increase remission in young patients with Graves’ disease.
Graves’ disease is an autoimmune condition causing hyperthyroidism and antithyroid drugs may affect the autoimmune process and cause it to go into remission. Rituximab is a monoclonal antibody that has been shown to be effective in treating other autoimmune diseases. In the current study, disease remission and treatment safety were evaluated in young patients with Graves’ disease when Rituximab was administered together with antithyroid drugs.

THYROID AND CANCER
Pre-existing thyroid autoimmunity is associated with increased thyroid cancer risk
Autoimmune disease is a major cause of thyroid problems in the US. Previous studies have suggested an association between autoimmune thyroid disease and thyroid cancer. The aim of this study is to determine whether there is an association of thyroid cancer with autoimmune thyroid disease.

Lack of an impact of education and income on the increase of thyroid cancer in Denmark
Similar to the United States, thyroid cancer has been increasing in other parts of the world. Indeed, the occurrence of new cases of thyroid cancer in Denmark has increased considerably from 1980 to 2014. The goal of the study was specifically to evaluate how the level of education and income of adults in Denmark was associated with the increase in thyroid cancer.
Sørensen SM et al 2022 Temporal trends in papillary and follicular thyroid cancer incidence from 1995 to 2019 in adults in Denmark according to education and income. Thyroid. Epub 2022 Apr 22. PMID: 35459415.
