Prevalence and clinical determinants of rapid eGFR decline among patients with newly diagnosed type 2 diabetes.
Diabetic kidney disease is the most common cause of end-stage kidney disease (ESKD) in the western world. Rapid estimated glomerular filtration rate (eGFR) decline is an independent predictor of ESKD and death in the general population and in subjects with type 2 diabetes mellitus (T2D). ⋯ Our study demonstrates that a significant percentage of newly diagnosed T2D subjects have a rapid eGFR decline. Given the association between dynamic changes in eGFR and the risk of ESKD or death, we suggest to include this variable in the definition of CKD.

Impaired insulin sensitivity measured by estimated glucose disposal rate is associated with decreased myocardial mechano-energetic efficiency in non-diabetic individuals.
Impaired myocardial mechano-energetic efficiency (MEE) has been associated with cardiac insulin resistance measured by dynamic positron emission tomography (PET) with 18F-fluorodeoxyglucose (18F-FDG) combined with euglycemic-hyperinsulinemic clamp. Estimate glucose disposal rate (eGDR) index has a good correlation with whole-body insulin sensitivity. It remains unsettled whether eGDR index is a suitable proxy of cardiac insulin sensitivity as well as its association with myocardial MEE. The aims of this study were: 1) to compare eGDR index with HOMA-IR, QUICKI and FIRI indexes for association with myocardial glucose metabolic rate (MrGlu); and 2) to determine the association of eGDR index with myocardial MEE. ⋯ These data suggest that the eGDR index may be a useful marker to identifying individuals at high cardiovascular risk.

Worsening Heart Failure (WHF) is associated with adverse prognosis. Identifying novel prognostic markers in WHF is crucial. Gait speed (GS), a validated frailty index, is an easily obtainable parameter that may aid in reclassifying the risk of HF patients. We assessed the independent prognostic role of GS in WHF patients. ⋯ GS, an easily obtainable marker of frailty, may contribute to improve the risk stratification of patients with WHF.
