IN BRIEF This study aimed to assess readiness to transition from pediatric to adult health care in adolescents with type 1 diabetes using the Transition Readiness Assessment Questionnaire (TRAQ). TRAQ is a non–disease-specific self-report measure that assesses self-management and advocacy skills of youth with special health care needs. This study provides guidance on assessing transition readiness scores of adolescents with diabetes and identifying when health care providers should intervene.
Local modulation of glucocorticoid action in adipocytes regulates adiposity and systemic insulin sensitivity. However, the specific cofactors that mediate glucocorticoid receptor (GR) action in adipocytes remain unclear. Here we show that the silencing mediator of retinoid and thyroid hormone receptors (SMRT) is recruited to GR in adipocytes and regulates ligand-dependent GR function. Decreased SMRT expression in adipocytes in vivo increases expression of glucocorticoid-responsive genes. Moreover, adipocytes with decreased SMRT expression exhibit altered glucocorticoid regulation of lipolysis. We conclude that SMRT regulates the metabolic functions of GR in adipocytes in vivo. Modulation of GR-SMRT interactions in adipocytes represents a novel approach to control the local degree of glucocorticoid action and thus influence adipocyte metabolic function.
Objective:To determine the association, if any, between thyroid-stimulating hormone (TSH) levels and body mass index (BMI) percentiles in children with primary hypothyroidism who are chemically euthyroid and on treatment with levothyroxine.Methods:This retrospective cross-sectional study consisted of a review of medical records from RUSH Medical Center and Stroger Hospital, Chicago, USA of children with primary hypothyroidism who were seen in the clinic from 2008 to 2014 and who were chemically euthyroid and on treatment with levothyroxine for at least 6 months. The patients were divided into two groups based on their TSH levels (0.34-<2.5 mIU/L and ≥2.5-5.6 mIU/L). The data were analyzed by Spearman rank correlation, linear regression, cross tabulation and chi-square, Mann-Whitney U test, and Kruskal-Wallis test.Results:One hundred and forty-six children were included, of which 26% were obese (BMI ≥95%), 21.9% overweight (BMI ≥85-<95%), and 52.1% of a healthy weight (BMI ≥5-<85%). There was a significant positive correlation between TSH and BMI percentiles (r=0.274, p=0.001) and a significant negative correlation between TSH and serum free T4 (r=-0.259, p=0.002). In the lower TSH group, 68.4% of the children had a healthy weight, while the percentage of obese children was 60.5% in the upper TSH group (p=0.012).Conclusion:In children diagnosed with primary hypothyroidism who are chemically euthyroid on treatment with levothyroxine, there is a positive association between higher TSH levels and higher BMI percentiles. However, it is difficult to establish if the higher TSH levels are a direct cause or a consequence of the obesity. Further studies are needed to establish causation beyond significant association.
Introduction: Thyroid nodules are less common among children than adults but are more likely to be malignant. Among all the thyroid nodules, autonomous functioning thyroid nodules (AFTN) are generally considered to be a benign entity, with malignancy found in less than 1 %. AFTN are very rare in the pediatric population, and the optimal treatment is not well defined. We present a 14-year-old female patient with an AFTN treated with surgical resection and found to contain papillary thyroid carcinoma, despite a previous biopsy which did not demonstrate malignancy. Case presentation: A 14-year-old girl presented with left-sided palpable thyroid lesion for four months. The patient had no symptoms at that time, and the physical exam was notable for a palpable left thyroid nodule measuring 3x 2.2 cm. Thyroid studies were remarkable for a suppressed thyroid-stimulating hormone (TSH) of 0.056uIU/mL (0.350–4.94), normal free thyroxine (FT4): 1.1 ng/dL (0.7–1.5), and positive anti-thyroglobulin antibodies: 9.0 IU/ml (0.0 - 4.1) with negative anti peroxidase antibodies and negative thyroid-stimulating immunoglobulin. Initial ultrasound (US) showed a left complex cystic and solid nodule measuring 3.4 cm x 1.8 cm x 2.3 cm. Fine needle aspiration (FNA) of the nodule revealed a benign aspirate. An I-123 scan revealed a hyperfunctioning nodule with suppression of uptake in surrounding thyroid parenchyma. The patient was then lost to follow up, presenting to our clinic over a year later due to difficulty breathing when supine and increased nodule size. Thyroid studies were notable for a suppressed TSH of 0.005 and slightly elevated FT4:1.8. Thyroid US showed a mixed cystic and solid nodule measuring 4.7 x3 x 4cm, with no calcification. Given the increased size of the lesion, her age, and difficulty breathing when supine, a decision was made to proceed with left hemithyroidectomy for definitive diagnosis and treatment. Pathology of the specimen revealed an encapsulated papillary thyroid carcinoma with focal capsular invasion. Right hemithyroidectomy was performed three weeks later, followed by I-131 ablation one month after surgery. The patient is currently doing well and euthyroid on thyroid hormone replacement therapy, with no evidence of disease. She is undergoing surveillance with ultrasound imaging and laboratory evaluation. Conclusion: This is a rare case of AFTN harboring papillary thyroid carcinoma. Although the majority of cases of AFTN are benign, an FNA was performed and was negative for malignancy. Due to an increase in size, new symptoms and ultrasound changes, surgery was performed and revealed the final diagnosis. The behavior of thyroid nodules in pediatric patients can be different than adult patients. Even though the majority of AFTN are benign, we should still keep malignancy in our differential when the nodule has a growth pattern, new US findings or patient develops worsening symptoms.
