Article Synopsis
  • - The study aimed to analyze the acute phase of COVID-19 in hospitalized patients and create a prognostic scale for assessing their risk of death.
  • - It involved 9,364 patients from 26 medical centers across seven countries, using a machine learning model called "Random Forest" to identify key factors related to in-hospital mortality.
  • - The resulting ACTIV scale, developed from 11 significant variables, showed a strong predictive ability with 89.2% accuracy, aiding clinicians in evaluating the prognosis of COVID-19 patients.

Unlabelled: Multiple trials have demonstrated the efficacy of fenofibrate for the management of dyslipidemia. Real-world evidence may provide important insights into the effectiveness and safety of fenofibrate in patients with metabolic syndrome and elevated triglyceride (TG) levels, but such evidence is currently scarce.

Materials And Methods: A non-interventional study was conducted among routine healthcare providers.

Aims: To study all-cause mortality in patients hospitalized with COVID-19 with or without chronic heart failure (CHF) during hospitalization and at 3 and 6 months of follow-up.

Methods And Results: The international registry Analysis of Comorbid Disease Dynamics in Patients with SARS-CoV-2 Infection (ACTIV) was conducted at 26 centres in seven countries: Armenia, Belarus, Kazakhstan, Kyrgyzstan, Moldova, Russian Federation, and Uzbekistan. The primary endpoints were in-hospital all-cause mortality and all-cause mortality at 3 and 6 months of follow-up.

Background: Maintaining sustained adherence to medication for optimal management of chronic noninfectious diseases, such as atherosclerotic vascular disease, is a well-documented therapeutic challenge.

Objective: The DIAPAsOn study was a 6-month, multicenter prospective observational study in the Russian Federation that examined adherence to a preparation of highly purified omega-3 polyunsaturated fatty acids (Omacor) in 2167 adult patients with a history of recent myocardial infarction or endogenous hypertriglyceridemia.

Methods: A feature of DIAPAsOn was the use of a bespoke electronic patient engagement and data collection system to monitor adherence.

Background: Sustained adherence and persistence with prescription medications is considered essential to achieve maximal treatment benefit for patients with major chronic, noncommunicable diseases such as hyperlipidemia and lipid-associated cardiovascular disease. It is widely documented, however, that many patients with these conditions have poor long-term adherence to their treatments. The population of Russia is affected by poor adherence in the same ways as populations elsewhere and continues to have high rates of cardiovascular disease.

Aims: Iron deficiency (ID) is a common co-morbidity in patients with heart failure (HF) and has been suggested to be associated with poor prognosis. Recently completed double-blind randomised controlled trials (RCTs) studying HF patients with ID have shown improvements in functional capacity, symptoms and quality of life when treated with i.v.

Chronic heart failure is a systemic disease with a devastating prognosis, which affects many organ systems other than the cardiovascular system. A total of 45 Chronic heart failure patients of ischemic etiology and 18 control subjects aged 45-65 years were recruited. All subjects underwent a physical examination by a qualified physician, echocardiography, an evaluation of the trophological status (including height and weight assessment) and net-of-fat body mass (NFBM) determination, an evaluation of intestinal functional activity based on fat and protein excretion with feces, and biopsy examination from the small intestine (see below).
