[SGLT2i: Exploring Multiple Pathways in Cardiorenal Protection. Insights Into Nutrient Deprivation].

SGLT-2 inhibitors are a relatively new class of antidiabetic drugs. They activate a transcriptional response similar to calorie restriction characterized by the up-regulation of sensors involved in nutrient deprivation, such as SIRT1 and AMPK, and the down-regulation of mTOR, a molecule involved in nutritional excess signaling. The purpose of this review is to illustrate the main pathways of nutrient deprivation: a complex mechanistic framework partly responsible for the cardio-renal benefits that makes these drugs unique.

[HIF-ɑ: New Target For Treatment of Renal Anemia. Molecular Aspects and Activation of Pathway HREs].

Roxadustat, recently approved, is a hypoxia-inducible factor prolyl hydroxylase inhibitor that has demonstrated favorable safety and efficacy in the treatment of renal anemia. This article reviews main features and possible effects by activation of pathway sequences HREs.

Hemodialysis in patients requiring 131I treatment for thyroid carcinoma.

Purpose: Thyroid malignancies can be treated by surgery followed by ablation of the remnant tissue with 131I. As iodide removal from the body occurs by renal extraction, in patients suffering from end-stage renal disease it is necessary to properly evaluate both timing and method of the extracorporeal treatment.


Methods: We present two patients on regular hemodialysis, admitted in isolation to the Nuclear Medicine Department and treated with 131I for thyroid carcinoma diagnosed during the check-up for transplantation.

Microsurgery and preventive haemostasis for autogenous radial-cephalic direct wrist access in adult patients with radial artery internal diameter below 1.6 mm.

Background: Autogenous radial-cephalic direct wrist arteriovenous fistula (RCF), the gold standard for chronic dialysis, suffers from an elevated early failure rate (up to 20-50% with a pooled rate of 15.3%). Guidelines indicate that a small radial artery internal diameter (<1.
