Objective: To assess the landscape of digital health resources in the United States, better understand the impact of the digital health on shared decision-making, and identify potential barriers and opportunities for progress in the care of persons with diabetes.

Methods: The study consisted of two phases: A qualitative phase in which one-on-one interviews were conducted virtually with 34 physicians (endocrinologists {Endos}: n = 15; primary care physicians {PCPs}: n = 19) between February 11, 2021 and February 18, 2021, and a quantitative phase in which two online, email-based surveys in the English language were conducted between April 16, 2021 and May 17, 2021: one with healthcare professionals (HCP) (n = 403: n = 200 Endos and n = 203 PCPs), and one with persons with diabetes (n = 517: patients with type 1 diabetes, n = 257; patients with type 2 diabetes, n = 260).

Results: Diabetes digital health tools were found to be helpful in shared decision-making, but leading barriers include cost, coverage, and lack of time by healthcare professionals.

Background: Analysis of cytologically indeterminate thyroid nodules with Afirma Gene Expression Classifier (GEC) and Genomic Sequencing Classifier (GSC) can reduce surgical rate and increase malignancy rate of surgically resected indeterminate nodules.

Methods: Retrospective cohort analysis of all adults with cytologically indeterminate thyroid nodules from January 2013 through December 2019. We compared surgical and malignancy rates of those without molecular testing to those with GEC or GSC, analyzed test performance between GEC and GSC, and identified variables associated with molecular testing.

Introduction: Management of post-transplant diabetes mellitus is challenging; there is a lack of prospective randomized controlled trials for safety and efficacy of antidiabetic medications in solid organ recipients. Glucagon-like peptide 1 receptor agonists (GLP-1RA) are a relatively new class of medications used to manage type 2 diabetes in the general population. They have several benefits besides glycemic control, including weight loss and improved cardiovascular risk.

We previously reported that fish oil in combination with cyclooxygenase (COX) inhibitors exerts enhanced hypolipidemic and anti-inflammatory effects in mice. Here, we sought to determine the effects of omega-3 polyunsaturated fatty acids (ω-3 PUFAs) in combination with naproxen (NX), a COX inhibitor, on dyslipidemia and gene expression in adipose tissue (AT) in humans. Obese dyslipidemic patients were randomly assigned to one of these interventions for 12 wk: 1) Standard nutrition counseling (control), 2) ω-3 PUFAs (2 g twice daily), 3) NX (220 mg twice daily), and 4) ω-3 PUFAs (2 g twice daily) + NX (220 mg twice daily).

Post-transplant diabetes mellitus (PTDM) is common after most types of solid organ transplantation, though the actual incidence is as yet unknown because of the use of different diagnostic criteria. PTDM is the result of individual risk factors as well as risk factors associated with the transplant itself, particularly immunosuppressants. Previously called New Onset Diabetes, in many cases inadequate screening for diabetes before transplant cannot assure that the diabetes is new after transplant.

Aims: The aim of this study was to compare the changes in the total daily dose (TDD) of insulin of patients on U-500 insulin; before hospitalization, during hospitalization and six weeks after discharge.

Methods: A retrospective chart review of veterans with type 2 diabetes receiving U-500 insulin in the ambulatory setting and who were admitted between 2012 and 2015 was performed. During hospitalization, patients were transitioned to receive U-100 insulin (detemir or glargine for basal and aspart for bolus).

The dramatic rise in the prevalence of obesity and diabetes is associated with increased morbidity, mortality, and public health care costs worldwide. The need for new, effective, and long-lasting drugs is urgent. Recent research has focused on the role of the inhibitors of sodium- glucose co-transporter 2 (SGLT-2).

A rare cause for rapid adrenal enlargement is adrenal oncocytoma of uncertain malignant potential. A full biochemical evaluation is warranted to screen secreting adrenal adenomas as well as to evaluate adrenal cortical carcinoma. Careful pathologic evaluation is required as the diagnosis of AOC cannot be made by imaging.

Post-transplant diabetes mellitus (PTDM) is a frequent consequence of solid organ transplantation. PTDM has been associated with greater mortality and increased infections in different transplant groups using different diagnostic criteria. An international consensus panel recommended a consistent set of guidelines in 2003 based on American Diabetes Association glucose criteria but did not exclude the immediate post-transplant hospitalization when many patients receive large doses of corticosteroids.

Significant hyperglycemia is commonly observed immediately after solid organ and bone marrow transplant as well as with subsequent hospitalizations. Surgery and procedures are well known to cause pain and stress leading to secretion of cytokines and other hormones known to aggravate insulin action. Immunosuppression required for transplant and preexisting risk are also major factors.

New-onset diabetes after transplantation (NODAT) is a common comorbidity after renal transplantation. Though metformin is the first-line agent for the treatment of type 2 diabetes, in renal transplant recipients, metformin is frequently avoided due to concerns about renal dysfunction and risk for lactic acidosis. Therefore, alternative first-line agents for the treatment of NODAT in renal transplant recipients are needed.

Although the contribution of the immunosuppressants tacrolimus (TAC) and sirolimus (SIR) to the development of posttransplant diabetes mellitus (PTDM) are being increasingly recognized, the mechanisms of immunosuppressant-induced hyperglycemia are unclear. SIR induces insulin resistance predominantly, but is associated with β-cell dysfunction in rodents. TAC affects islet function but is associated with worsening insulin sensitivity in a few, and improvement in some, clinical studies.

Background: Immunosuppressants are an important cause of posttransplantation diabetes mellitus. We have shown that tacrolimus and sirolimus induce hyperglycemia and hyperinsulinemia in normal rats. We hypothesized that metformin, given concurrently with tacrolimus and/or sirolimus, prevents disturbances in glucose and insulin metabolism.

Kidney transplantation is being performed more frequently for individuals with end stage renal disease (ESRD) due to improved survival and quality of life compared to long-term dialysis. Though rates decrease after transplant, cardiovascular disease (CVD) remains the most common cause of death after kidney transplant. New-onset diabetes after transplant (NODAT), a common complication following kidney transplantation, and pre-transplant diabetes both significantly increase the risk for CVD.

Background: Immunosuppression medications contribute to posttransplant diabetes mellitus in patients and can cause insulin resistance in male rats. Tacrolimus (TAC)-sirolimus (SIR) immunosuppression is also associated with appearance of ovarian cysts in transplant patients. Because insulin resistance is observed in patients with polycystic ovary syndrome, we hypothesized that TAC or SIR may induce reproductive abnormalities.

Post-transplant diabetes mellitus (PTDM) worsens outcomes after kidney transplantation, and immunosuppression agents contribute to PTDM. We have previously shown that tacrolimus (TAC) and sirolimus (SIR) cause hyperglycemia in normal rats. While there is little data on the mechanism for immunosuppressant-induced hyperglycemia, we hypothesized that the TAC and SIR-induced changes are reversible.

The increase in obesity and the aging of the population has lead to an increase in the incidence of type 2 diabetes. This has led to the development of new drugs such as thiazolidinediones (TZDs) which are Peroxisome Proliferator-Activated Receptor (PPARgamma) agonists, to treat type 2 diabetes. TZDs have recently been at the center of a controversy with regards to their cardiovascular safety.

Background: Patients with diabetes have been reported to have greater dyslipidemia after kidney transplant (KTX). Because postKTX management of diabetes has changed markedly since those reports, we hypothesized that lipids can be controlled as well in diabetic as in nondiabetic recipients.

Methods: We compared lipid levels up to 2 years after KTX (n=192) between diabetic and nondiabetic recipients.

Ept1, Ept2, Ept6, and Ept9 are quantitative trait loci mapped in crosses between the ACI and Copenhagen (COP) rat strains as genetic determinants of responsiveness of the pituitary gland to estrogens. We have developed four congenic rat strains, each of which carries, on the genetic background of the ACI rat strain, alleles from the COP rat strain that span one of these quantitative trait loci. Relative to the female ACI rats, female ACI.
