An integrated approach based on uniform quantization for the evaluation of complexity of short-term heart period variability: Application to 24 h Holter recordings in healthy and heart failure humans.
We propose an integrated approach based on uniform quantization over a small number of levels for the evaluation and characterization of complexity of a process. This approach integrates information-domain analysis based on entropy rate, local nonlinear prediction, and pattern classification based on symbolic analysis. Normalized and non-normalized indexes quantifying complexity over short data sequences (â¼300 samples) are derived. This approach provides a rule for deciding the optimal length of the patterns that may be worth considering and some suggestions about possible strategies to group patterns into a smaller number of families. The approach is applied to 24 h Holter recordings of …
GLP-1 receptor agonists, carotid atherosclerosis and retinopathy
It is known that diabetes is associated with the development of premature atherosclerosis and microvascular complications and consequently increased cardiovascular (CV) morbidity and mortality. In ...
Comparison of Reported Deaths From COVID-19 and Increase in Total Mortality in Italy
This analysis compares reported deaths from COVID-19, February 23 to April 4, 2020, and total mortality in Italy from January 12 through April 4 in the years 2015 through 2020.
Diabetes and renin-angiotensin-aldosterone system: Implications for covid-19 patients with diabetes treatment management
In the context of the COVID-19 continuous spreading, this paper focuses on the increased risk of diabetic patients regarding the metabolic control and the uncertainties related to SARS-CoV-2 infection. Chronic hyperglycaemia negatively affects the immune system, which triggers an increase of morbidity and mortality for viral infections. A key aspect of COVID-19 resides in the involvement of renin-angiotensin-aldosterone (RAAS) system that causes a cascade of reactions mediated by vasoactive peptides with implications in vasoconstriction, vascular permeability, oxidative stress remodelling and tissue injuries. Activation of RAAS at pulmonary level, is responsible for the local damage. Many q…
