Article Synopsis
  • Metformin has been a staple in treating type 2 diabetes for years and is also used off-label for conditions like gestational diabetes and polycystic ovarian syndrome due to its insulin-sensitizing properties.
  • In 2022, it became the only oral medication approved by the European Union for managing diabetes during pregnancy, showing safety and benefits for mothers while crossing the placenta to the baby.
  • Benefits for mothers include reduced weight gain and lower risk of pre-eclampsia; however, long-term effects on their children are still uncertain, necessitating further research on potential concerns like small-for-gestational-age (SGA) outcomes.

Objective: Autonomously functioning thyroid nodules (AFTN) can be treated with antithyroid drugs, radioactive iodine (RAI), thyroid lobectomy or radiofrequency ablation (RFA). Although surgery is most definitive, some patients require lifelong hormone supplementation. RFA avoids this sequela, but its efficacy depends on nodule size.

Insulin autoimmune syndrome (IAS), or Hirata's disease, is a rare disease characterized by episodes of hypoglycemia with elevated levels of insulin secondary to high concentrations of insulin autoantibodies. The use of methimazole is a risk factor for the development of Hirata's disease. We report a case of a 47-year-old man being treated for thyroid storm initially with methimazole and other agents.

Purpose Of Review: Targeting specific steroidogenic enzymes is effective in decreasing testosterone synthesis, resulting in significant antitumor effects in prostate cancer. Such treatments result in disruptions of complicated and intertwining pathways with systemic physiologic consequences via effects on the adrenal gland and renin-angiotensin-aldosterone axis. This review highlights some of these aspects that need to be taken into consideration when treating patients with androgen biosynthesis inhibitors.

Purpose: To the best of our knowledge, implementation of artificial intelligence (AI)-based vision screening in community health fair settings has not been previously studied. This prospective cohort study explored the incorporation of AI in a community health fair setting to improve access to eyecare.

Methods: Vision screening was implemented during a community health fair event using an AI-based non-mydriatic fundus camera.

Social and health disparities among transgender people may result in increased rates of incarceration, particularly among Black transgender women. The World Professional Association for Transgender Health states that all recommendations for gender-affirming care made in the Standards of Care-8 be applied equally to people living in institutions. Understanding the structural challenges to gender-affirming care in the corrections environment will allow the endocrinologist to navigate the complex correctional health care system.

Telemedicine can be an effective tool for managing chronic diseases. The disruption in traditional diabetes care resulting from the COVID-19 pandemic led to global interest in telemedicine. With this manuscript, we evaluated the use of telemedicine for the management of diabetes during the pandemic and its impact on glycemic control, focusing on retrospective and prospective studies which included adult, non-pregnant patients with diabetes.

Electroconvulsive therapy (ECT) is a treatment modality for refractory depression and other severe psychiatric diseases. Depression is a common comorbid condition of diabetes. Yet, evidence regarding the effect of ECT on glycemic control in patients with diabetes is limited and conflicting, with reports of both exacerbation and amelioration of hyperglycemia.

Background: Patients with Graves' disease treated with radioactive iodine report worse quality of life than those treated by thyroidectomy. However, radioactive iodine is often selected due to lower risk of complications and lower cost. The objective of this study was to estimate the cost-effectiveness of radioactive iodine versus total thyroidectomy for treatment of Graves' disease.

A 40-year-old woman used an open-source automated insulin delivery system to manage her type 1 diabetes (T1D) prior to conception. The code for building the iPhone application called 'Loop' that carried the software for the hybrid closed-loop controller was available online. Her glycated hemoglobin before conception was 6.

Objective: Diabetes is an independent risk factor for severe SARS-CoV-2 infections. This study aims to elucidate the risk factors predictive of more severe outcomes in patients with diabetes by comparing the clinical characteristics of those requiring inpatient admissions with those who remain outpatient.

Methods: A retrospective review identified 832 patients-631 inpatients and 201 outpatients-with diabetes and a positive SARS-CoV-2 test result between March 1 and June 15, 2020.

Although diabetes remains the number one cause of renal failure nationwide, spontaneous hypoglycemia in patients with CKD has also been described in the absence of exogenous insulin or any other diabetes treatment. Decreased renal gluconeogenesis and impaired renal insulin clearance are underlying mechanisms of hypoglycemia in individuals with ESRD. Diazoxide was originally approved as an anti-hypertensive medication, but also is known to bind ATP-sensitive K channels in the beta cells of the pancreas, ultimately leading to inhibition of insulin release.

Anti-N-methyl-D-aspartic acid-receptor (NMDA-R) encephalitis is a novel disease discovered within the past 10 years. It is an autoimmune disease (AD) that has been associated with other ADs, such as Graves' disease. However, association with autoimmune polyglandular syndromes (APS) has not been previously described.

Introduction: Posaconazole is an azole used in treatment and prophylaxis of a broad spectrum of fungal infections. Antifungals such as ketoconazole have been shown to cause primary adrenal insufficiency (AI) as a result of direct inhibition on the steroidogenesis pathway. There is only one reported case of primary AI induced by posaconazole in a patient with mucormycosis.

Polycystic ovarian syndrome (PCOS) affects many women of child-bearing age and is characterized by hyperandrogenism, ovulatory and metabolic dysfunction. A primary treatment goal is weight reduction. The weight loss effects of glucagon-like peptide-1 receptor agonists (GLP-1RA), previously demonstrated in diabetic and obese non-diabetic patients, offer a unique opportunity to expand the medical options available to PCOS patients.
