Methodology and implementation of the WHO European Childhood Obesity Surveillance Initiative (COSI)

Establishment of the WHO European Childhood Obesity Surveillance Initiative (COSI) has resulted in a surveillance system which provides regular, reliable, timely, and accurate data on children's weight status—through standardized measurement of bodyweight and height—in the WHO European Region. Additional data on dietary intake, physical activity, sedentary behavior, family background, and school environments are collected in several countries. In total, 45 countries in the European Region have participated in COSI. The first five data collection rounds, between 2007 and 2021, yielded measured anthropometric data on over 1.3 million children. In COSI, data are collected according to a common protocol, using standardized instruments and procedures. The systematic collection and analysis of these data enables intercountry comparisons and reveals differences in the prevalence of childhood thinness, overweight, normal weight, and obesity between and within populations. Furthermore, it facilitates investigation of the relationship between overweight, obesity, and potential risk or protective factors and improves the understanding of the development of overweight and obesity in European primary-school children in order to support appropriate and effective policy responses

Возможности различных протоколов экстракорпоральной ударно-волновой терапии в лечении стабильной стенокардии

Aim. To evaluate effects of various protocols of cardiac shock wave therapy (CSWT) on quality of life and exercise tolerance in patients with stable angina against the background of optimal medication therapy (OMT). Material and methods. Overall 53 patients (37 men, 16 women) were included in the study. The mean age of examined patients was 67,3±8,1 years. Inclusion criteria: CCS class I-IV angina pectoris, stable therapy for at least 1 month before inclusion in the study and a stable course of coronary artery disease for more than 3 months (no cardiovascular events) before inclusion in the study. Patients were divided into 2 groups. The Group 1 (n=37) received OMT+CSWT standard-modified protocol, Group 2 (n=16) received OMT+CSWT rapid-modified protocol. Electrocardiography, echocardiography, treadmill test, and Seattle quality of life questionnaire (SAQ) were performed at inclusion and 6 months follow up. Results. Both CSWT with rapid-modified protocol and standard-modified protocol significantly reduced the number of short-acting nitrates from 2 (2; 7) to 1 (0; 2) (p=0,04) and from 2 (0; 6) to 0 (0; 2) (p≤0,001) at 6 months, respectively, as well as the number of angina attacks per week (from 4 (2; 7) to 1 (1; 1) (p=0,007) and 6 (2; 20) to 1 (0; 5) (p≤0,001). Treadmill test total exercise duration was significantly increased from 393 (326; 574) to 561 (411; 650) seconds (p=0,007) and 365±140,4 to 411,5±156,1 seconds (p=0,01), respectively. Time to 1 mm ST segment depression was also significantly increased from 399,8±169 to 460±182 seconds (p≤0,05) and from 303,1±179 to 389,9±203 seconds (p=0,001), respectively. Conclusion. In our study, CSWT with rapid-modified protocol improved quality of life and exercise tolerance in patients with stable angina similar to the standard-modified protocol. Rapid-modified protocol of CSWT reduced total duration of the treatment
