Objective: To evaluate the impact of a decision support system (DSS) based on artificial intelligence (AI) -KoiosDS- on ultrasound (US) image analysis and risk stratification in thyroid nodules.Material and methods: Retrospective US study of all thyroid nodules with histologic (AP) result from June 2020 to December 2021. Diagnostic performance of US with ACR-TIRADS, by six endocrinologists and DSS, before and after the use of AI was evaluated.<p clas...

Background: Metformin is one of the first line drugs used to treat type 2 diabetes mellitus, even though there are still many gaps on how exactly metformin works. This is due to many years of research using various concentrations of metformin and also, not considering the conditional effect that glucose can have in its action.Objectives: Study the effect of different concentrations of metformin and glucose in cell culture.Methods: ...

Objective: The definitive treatment of primary hyperparathyroidism (PPH) is the removal of the affected gland(s). However, its localization can be complicated. The usefulness of 18F-Choline PET-CT versus classical techniques is unknown. The aim of this study was to evaluate the results of 18F-Choline PET-CT in the detection of hyperfunctioning parathyroid tissue with respect to conventional imaging tests and to analyze the relationship between its findings and the levels of ca...

Objective: Endogenous cushing syndrome (ECS) is a complex and rare disease. After treatment, 50% of cases have recurrence. The objective is to evaluate the prevalence of recurrences in patients diagnosed of ECS and its predictive factors.Materials and Methods: Analytical retrospective observational study with 19 ECS diagnoses cases followed-up from January 1999 to December 2023. Demographic (sex, age), clinical (cause, face plethora, fragile capillary, r...

Type 2 diabetes is among the most prevalent chronic diseases worldwide. Further research is needed to identify new mechanisms that may help preserve the function of insulin-secreting pancreatic β-cells. The cannabinoid receptors type 1 (CB1) and their endogenous ligands, endocannabinoids, exert a key role in regulating of glucose homeostasis, β-cells function, and insulin secretion. Intriguingly, CB1 is not only located at the plasma membrane (pmCB1), but also at the...

Background: Gestational diabetes mellitus (GDM) is common complication in pregnancy. During pandemic COVID-19, endocrine service iniciate telemedicine in medical care and monitoring blood glucose.Purpose: The purpose of this study was to asses metabolic control and pregnancy outcome during pregnancy in telematic consult.Materials and Methods: Descriptive study of 20 patients were assesed in telematic review in the first wave of the...

Introduction: Nelson´s Syndrome is defined as the presence of an enlarging pituitary tumor associated with elevated fasting plasma ACTH levels and hyperpigmentation in patients submitted to bilateral adrenalectomy for the treatment of Cushing´s disease. Case Report: We present a case of a 48 y/o woman who in 2015, was diagnosed of Cushing’s disease and underwent transsphenoidal adenomectomy but remission was not achieved, so the patient wa...

Introduction: Neutropenia can indicate infectious and hematological pathology but it can also be a sign of hyperthyroidism. For this reason, it has been suggested to perform a complete blood count before starting treatment with antithyroid drugs in case of new-onset hyperthyroidism. Antithyroid drugs can cause severe neutropenia, also called agranulocytosis, when the neutrophil count is less than 500/µl. Therefore, the use of these drugs should be reconsidered if it is le...

Introduction: Zinc transporter 8 (ZnT8) autoimmunity has been established as one of the markers for the diagnosis of type 1 diabetes (T1D) along with glutamate decarboxylase (GAD) and tyrosine phosphatase IA-2 (IA-2) antibodies. The aim of this study is to understand the status of pancreatic autoimmunity in the diagnosis of T1D, with special attention to the usefulness of ZnT8. In addition, as a second objective, we study the proposal to perform the assessment of pancreatic au...

Background and aim: Dual energy X-ray absorptiometry (DXA) is considered the gold standard to evaluate BC, even if it requires the use of radiations, an expensive equipment and cannot be performed at the patient’s bedside. Nutritional ultrasound (NU) evaluates BC through the assessment of muscle mass and the abdominal subcutaneous (superficial and deep-layer) and visceral adipose tissue. We aimed at comparing the accuracy and reliability of this emerging tool with DXA in ...
