Age and sex predict severity, remission, and recurrence in Graves’ disease
Graves’s disease can be treated with antithryoid medications with the goal of causing the Graves’ disease to go into remission, allowing the medications to be stopped and the thyroid function to return to normal. Identifying clinical factors that may predict remission with medications can help guide doctors and patients when deciding on the most appropriate therapy for each individual. This study was done to investigate how age and sex of patients affect the severity of the Graves’ disease, the chances of achieving remission and the risk of recurrence once treatment is stopped.

Risk factors for the development of thyroid eye disease in patients with Graves’ disease
Up to 50% of patients with Graves’ disease develop thyroid eye disease (TED). Moderate to severe TED is very serious and can significantly affect the appearance of the eyes and cause loss of vision. This study was performed to see if there were risk factors associated with TED and, in particular, with progression to severe TED.

Do surgeons support lobectomy for low-risk papillary thyroid cancer?
Given the excellent prognosis of thyroid cancer, in recent years,
thyroid experts, high volume thyroid surgeons and national
guidelines have recommended doing a lobectomy as opposed
to a total thyroidectomy for low risk thyroid cancers. The
authors of the study surveyed surgeons across the country
that had performed thyroid surgery in recent years to examine
their attitudes and performance of type of surgery for low risk

Initiation of thyroid hormone therapy is common following thyroid lobectomy for low risk thyroid cancer
Many patients with low risk thyroid cancer do fine after only a lobectomy. One advantage of a thyroid lobectomy is the possibility the patient will not need lifelong thyroid hormone therapy. However, after a lobectomy for thyroid cancer, thyroid hormone therapy may be indicated even if the TSH level is in the normal range. This study was performed to see how often patients who had a lobectomy for low-risk thyroid cancer needed thyroid hormone after the surgery.

Competing Risks of Death in Older Thyroid Cancer Patients
Most types of thyroid cancer have an excellent prognosis, with a 10 year survival of 85-90%. Thus, most thyroid cancer patients die of other causes and not related to the thyroid cancer. The objective of this study was to determine whether older adults with thyroid cancer are more likely to die from thyroid cancer or other diseases, and determine factors associated with each.

An evaluation of the management of thyroid nodules in children
While thyroid nodules are uncommon in children, they have a higher rate of cancer than in adults. The ATA developed guidelines in 2015 for the management of childhood thyroid nodules. The purpose of this study is to analyze the management of thyroid nodules in children and understand the clinical practice variations or differences when comparing clinical practices to the 2015 ATA guidelines.
