Coronary heart diseases/coronary artery diseases (CHDs/CAD), the most common form of cardiovascular disease (CVD), are a major cause for death and disability in developing/developed countries. CAD risk factors could be detected by physicians to prevent the CAD occurrence in the near future. Invasive coronary angiography, a current diagnosis method, is costly and associated with morbidity and mortality in CAD patients. The aim of this study was to design a computer-based noninvasive CAD diagnosis system with clinically interpretable rules. ⋯ The proposed method showed "substantial agreement" with the gold standard. This algorithm is thus, a promising tool for screening CAD patients.

During the 20(th) century, the share of elderly in the total population of the Earth has increased steadily. It is expected that this trend will continue in the 21(st) century. In 1950, the elderly (persons aged 60 years and older) were 8% of the world population; in 2000, is already 10%; and in 2050, according to United Nations projections, the proportion will reach 21%. This research on Kazakhstan provides demographic analysis from 1989 to 2012 and presents the main features of population' ageing through comparative analysis. ⋯ Life expectancy of the elderly population KZ after 65 years in 2010 was only 13.8 years, which is 6-9 years inferior to European and U.S. indices. Thus, increasing the retirement age is inappropriate for the current period.

We conducted our study on 1110 patients with breast masses in order to investigate different aspects of power Doppler sonography (PDS) for differentiating between benign and malignant breast lesions and their prognostication. ⋯ It seems that while malignant tumors have significantly higher number of vessels in comparison to benign one, since the number of vessels overlap between benign and malignant tumors, this aspect has little clinical usefulness in distinguishing or prognostication of breast masses. In contrast RI, PI, and vascularization pattern have an ability to differentiate and predict the prognosis of breast lesions.

Sepsis is a systemic inflammatory response to infection. Sepsis, which can lead to severe sepsis, septic shock, and multiple organ dysfunction syndrome, is an important cause of mortality. Pathogenesis is extremely complex. ⋯ In animal experiments, many drugs show good results. However, clinical research lacks. In future studies, the urgent need is to develop promising drugs in clinical trials.

The most common drug abuse among athletes is anabolic steroids which lead to the development of cardiovascular diseases and sudden death. Thus, the aim of this study was to evaluate cardiovascular outcomes of anabolic consumption in body building athletes. ⋯ Increase in SBP or DBP is a common complication of these drugs which can lead serious vascular disorders. The lower LDL cholesterol level might be due to the higher amounts of lipid consumption in these athletes.
