Predictors of postpartum glucose metabolism disorders in women with gestational diabetes mellitus.

BACKGROUND AND AIMS: Postpartum glucose metabolism disorders are a common problem in women with gestational diabetes mellitus (GDM). They are often underdiagnosed since many patients do not attend the postpartum screening. This study aims to assess predictors of postpartum glucose metabolism disorders and type 2 diabetes mellitus (T2DM) after GDM. MATERIAL AND METHODS: Retrospective study in women with GMD who underwent postpartum screening for glucose metabolism disorders (n = 2688). Logistic regression was used in the statistical analysis. RESULTS: 24.6% of women had postpartum glucose metabolism disorder. In multivariate analysis, pre-pregnancy body mass index (BMI) 25-30 kg/m2 (OR 1.46, 95%CI 1.05 to 2.02) or BMI ≥30 kg/m2 (OR 2.62, 95%CI 1.72 to 3.96), diagnosis of GDM before 20 weeks of pregnancy (OR 2.33, 95%CI 1.57 to 3.46), fasting plasma glucose after diagnosis of GDM ≥90 mg/dl (OR 2.12, 95%CI 1.50 to 2.98), postprandial glucose ≥100 mg/dl (OR 1.47, 95%CI 1.09 to 2.99), and HbA1c in the third trimester of pregnancy ≥5.3% (2.04, 95%CI, 1.52 to 2.75) were independent predictors for any postpartum glucose metabolism disorder. CONCLUSION: postpartum screening for T2DM should be performed in all women with GDM, and it is especially important not to lose follow-up in those with one or more predictive factors.

Efficacy of continuous glucose monitoring on maternal and neonatal outcomes in gestational diabetes mellitus: a systematic review and meta-analysis of randomized clinical trials.

AIMS: This systematic review aims to evaluate the effect of continuous glucose monitoring (CGM) on maternal and neonatal outcomes in gestational diabetes mellitus (GDM). METHODS: Two authors conducted a systematic search using PubMed, Embase, CENTRAL, CINAHL, Scopus, Web of Science, ClinicalTrials.gov and the World Health Organization International Clinical Trials Registry Platform. The inclusion criteria for the systematic review were randomized clinical trials that compared the effects of CGM and blood glucose monitoring (BGM) in women with GDM. A restricted maximum likelihood random-effects model was used for the meta-analysis. The measures of effect were risk ratios for categorical data and mean differences for continuous data. RESULTS: Of the 457 studies reviewed, six randomized clinical trials met the inclusion criteria. A total of 482 patients were included in the meta-analysis. The use of CGM was associated with lower HbA1c levels at the end of pregnancy (mean difference: -0.22; 95%CI -0.42 to -0.03) compared to BGM. Women using CGM also had less gestational weight gain (mean difference: -1.17, 95%CI -2.15 to -0.19), and their children had lower birth weight (mean difference: -116.26, 95%CI -224.70 to -7.81). No differences were observed in the other outcomes evaluated. CONCLUSION: Women with GDM using CGM may achieve lower average blood glucose levels, lower maternal weight gain and infant birth weight than women using BGM. Nevertheless, current evidence is limited by the low number of studies and the small sample sizes of these studies. Larger clinical trials are needed to better understand the effects of CGM in GDM.

Medical detransition following transgender identity reaffirmation: two case reports.

Background Recently, increased social and scientific attention has been paid to gender detransition, a phenomenon in which individuals discontinue gender-affirming medical interventions (GAMI) aimed at alleviating gender dysphoria (GD). Yet, clinical knowledge of detransitioners and their experiences is still scarce. Case reports published in the literature suggest that both internal and external factors may influence this decision. Methods Two transgender individuals treated for GD at a gender identity unit presented with a desire to discontinue GAMI. A description of their clinical evolution is presented. Results Increased body satisfaction, self-esteem, self-acceptance, and self-empowerment with respect to their transgender identity were mentioned by the patients as reasons for discontinuing gender-affirming treatments. Coinciding factors included reduced GD, positive changes in social environments, better interpersonal functioning, and higher levels of psychological well-being in general. Conclusions Gender detransition is an under-researched phenomenon. These cases highlight the need for a more nuanced approach to gender-related clinical presentations, which involves providing individuals the opportunity to work on their social ecosystems and explore alternative options to manage GD before initiating GAMI.

An Unusual Case of Hypopituitarism as an Adverse Effect of Vandetanib and Remission of Breast Metastases in a Patient with Medullary Thyroid Cancer.

INTRODUCTION: Tyrosine kinase inhibitors have been a breakthrough in the treatment of advanced medullary thyroid cancer (MTC), and they can prolong progression-free survival (PFS). CASE PRESENTATION: A patient with MTC and metastatic spread to the lymph nodes, lungs, bones, breast, and cerebellum started treatment with vandetanib. During treatment, she developed secondary adrenal insufficiency and hypogonadotropic hypogonadism. After 9 years of vandetanib therapy, the disease has not progressed and the patient maintains a complete response of the breast metastases and a partial response of the other metastatic lesions. CONCLUSION: To our knowledge, this is the first reported case of secondary adrenal insufficiency and hypogonadotropic hypogonadism related to therapy with vandetanib. Moreover, the prolonged PFS and the complete disappearance of some of the metastatic lesions in this patient are truly unusual.

Orbital Radioiodine Uptake on Scintigraphy in a Patient with Thyroid Cancer.

Background: Orbital radioiodine uptake in patients with thyroid cancer is very uncommon with only a few reported cases, most of them being metastasis. The accumulation of 131I in nonthyroidal tissues and body fluids can lead to false-positive results in scintigraphy, which are sometimes difficult to differentiate from true metastases. Case Report: A post-therapy 131I whole-body (WBI) scintigraphy in an asymptomatic 57-year-old female with papillary thyroid carcinoma (PTC) previously treated with total thyroidectomy and 6 ablative radioiodine doses showed a focal uptake in the right eyeball region. The lesion, placed in the orbital space, was surgically removed, and histology revealed a conjunctival inclusion cyst. Discussion: Ocular and orbital metastases from thyroid cancer, as well as some non-neoplastic disorders or contamination, are possible causes for 131I uptake in the orbital region in scintigraphy. Conjunctival inclusion cyst is a condition associated with incidental 131I uptake that had not been reported before and should be ruled out as a non-metastatic cause of orbital radioiodine uptake in patients with PTC.
