Arterial hypertension (AH) combined with diabetes mellitus accelerates development of damage of the kidney. Elevation of serum creatinine level, lowering of creatinine clearance or calculated glomerular filtration rate (GFR), microalbuminuria are independent prognostic factors of cardiovascular morbidity and mortality. Unfavorable outcomes of impaired renal function can be prevented or delayed with the help of appropriate interventions at early stages. There is an urgency to search for methods allowing to reveal in patients with cardiovascular diseases impairment of renal function at preclinical stages. In all patients with AH estimation of GFR using MDRD equation or creatinine clearance using Cockcroft-Gault formula as well as measurement of urinary protein excretion are necessary. The given article presents review of available literature data devoted to the problem of contemporary methods of early preclinical detection of renal damage.

Background: Prognostic prediction in heart failure (HF) is challenging and no single marker has proven effective. We propose an index based on B-type natriuretic peptide (BNP) and four widely available parameters.
Methods: We retrospectively analyzed adult outpatients with chronic HF with systolic dysfunction followed from January 2012 to December 2020.

Activated carbon is extensively utilized in blood purification applications. However, its performance has been significantly limited by their poor blood compatibility. In this work, 2,2,6,6-tetramethylpiperidinyl-1-oxyl (TEMPO)-oxidized cellulose nanofibers (TOCN) and activated carbon (AC) were used to form composite beads by the drop curing method to improve hemocompatibility.

Physical Activity (PA) provides numerous biological and psychological benefits, especially for cancer patients. PA mitigates treatment side effects, influences hormones, inflammation, adiposity, and immune function, and reduces symptoms of anxiety, depression, and fatigue. This study evaluates the impact of PA on these positive outcomes.

Purpose: Establishing an accurate prognosis remains challenging in older patients with cancer because of the population's heterogeneity and the current predictive models' reduced ability to capture the complex interactions between oncologic and geriatric predictors. We aim to develop and externally validate a new predictive score (the Geriatric Cancer Scoring System [GCSS]) to refine individualized prognosis for older patients with cancer during the first year after a geriatric assessment (GA).
Materials And Methods: Data were collected from two French prospective multicenter cohorts of patients with cancer 70 years and older, referred for GA: ELCAPA (training set January 2007-March 2016) and ONCODAGE (validation set August 2008-March 2010).
