Thyroid dysfunction is associated with increased risk of cardiovascular disease (CVD) in general population, but it remains controversial whether the treatment of differentiated thyroid cancer (DTC) including thyroidectomy and thyroid stimulating hormone suppression add any risk of CVD compared to general population. We performed a systematic review of observational studies reporting associations between DTC and CVD in MEDLINE, EMBASE, Web of Science and other source (PROSPERO...

Background: PD-1/PD-L1 blockade is one of the promising drugs in the treatment of advanced non-small cell lung cancer (NSCLC). and predicting drug effect is important due to unique pattern of response. Immune-related adverse event (IRAE) might be associated with favorable clinical outcome. Thyroiditis is the most common IRAE which can be easily detected with the measurement of thyroid hormone levels. However, the relationship between thyroid dysfunction during the use of PD-1/...

Background: Delayed thyroid-stimulating hormone (TSH) recovery during treatment of Graves’ disease is caused by long-term excessive thyroid hormone, which results in down-regulation of pituitary thyrotropic cells. However, it is unknown whether delayed TSH recovery exists after levothyroxine (LT4) dose adjustment in patients with differentiated thyroid cancer (DTC) who are taking a suppressive dose of LT4.Methods: We retrospectively reviewed 97 DTC ...

Background: The incidence and prevalence of overt hypothyroidism have been reported to be 2 to 4/1,000 population/year and 8 to 13/1,000 population, respectively, in foreign countries. As there has been no nationwide survey to obtain data in Korea, the present study investigated the incidence and prevalence of overt hypothyroidism in Korea using claims data provided by the Health Insurance Review and Assessment Service. The proportions of causative diseases for hypothyroidism ...

Background: Selenium is an important trace element for thyroid hormone metabolism and its deficiency can cause hypothyroidism. Serum or plasma selenium concentration has been known as best biomarker which reflects selenium intake and reserve. We preliminarily assessed the serum or urine selenium concentrations in patients with thyroid disease compared to healthy normal population. We also investigated the correlation of serum selenium concentration with urine selenium concentr...

Background: Three deiodinase genes (DIO) play an important role in thyroid hormone metabolism. Among them, type 2 iodothyronine deiodinase (DIO2) converts T4 to T3 in brain and impaired psychological well-being was reported in minor variants of DIO2. However, the prevalence of three DIOs and their relation to neuropsychological status has not been evaluated in Asian hypothyroid subjects.Methods: We prospectively enrolled 196 subjects who were taking levo...

Background: TSH suppression therapy has been associated with hip and vertebral fracture. However, the relationship between TSH suppression and bone mineral density (BMD) remains controversial. The aim of this study was to evaluate the effect of TSH suppression therapy on cortical bone geometry in differentiated thyroid cancer (DTC) patients.Methods: This study included 122 subjects (19 men, 27 premenopausal women, and 75 postmenopausal women) who have be...

Background: The association between thyroid cancer and skeletal outcomes has not been thoroughly investigated. We aimed to investigate the risk of osteoporotic fractures in patients with thyroid cancer compared with a matched control group.Methods: This retrospective cohort study included 2,514 patients with thyroid cancer and 75,420 matched controls from the Korean National Health Insurance Service-National Sample Cohort (NHIS-NSC, 2006-2019). Rates of ...

Background: We aimed to explore the relationship between continuous glucose monitoring (CGM)-derived indicators and the presence of albuminuria taking circadian features into consideration concurrently in Insulin-using patients with type 2 diabetes.Methods: We analyzed data from 129 insulin-treated type 2 diabetes patients in Korea University Ansan Hospital. Over 10 days, we collected time-series data using Dexcom G6, Fitbit, and food diaries, along with...

Background: Pasireotide is a second line treatment for acromegaly. Besides the growth hormone (GH) lowering efficacy, clinical use is limited by side effects on glycemic control. The aim of this study was to evaluate longitudinal changes in beta-cell function and insulin sensitivity induced by pasireotide therapy in patients with acromegaly.Methods: We performed a retrospective study in 33 patients. Efficacy (GH and IGF-I concentrations; tumor size) and ...
