Background and Objectives: Balance is the ability of an organism to maintain its position in space. Balance disorders in children can lead to injuries and limited physical activity. Balance maintenance changes throughout puberty as well as in response to external factors. The study aimed to evaluate the influence of anthropometric parameters on balance in children aged 10 to 13 years. Materials and Methods: 308 children were accessed to eligibility to participate in the study. After considering the inclusion and exclusion criteria the study included 223 participants (123 boys and 100 girls) aged 10 to 13 from elementary schools in Szczecin. The stabilometry of examineted children was performed using the SIGMA balance platform. Results: It was shown that the balance parameters in children aged 10 to 13 worsen with increasing body mass and height, and do not correlate with age. Conclusions: Rapid diagnosis and identification of postural disorders in children make it possible to start targeted physical exercises and to make the therapeutic process more effective and complex. Future research is needed to obtain more data and draw conclusions crucial for physiotherapy practice.

High alcohol intake leads to an inadequate diet and impaired absorption, transport, and utilization of nutrients in the body, which results in malnutrition. Micronutrient supplementation, such as vitamins A, E, group B vitamins, folic acid zinc, and selenium may have a positive effect on those patients. In this article, the actual supplementation recommendations for vitamins and microelements in ethanol-induced liver disease patients are presented.

Calprotectin is a cytosol protein of granulocytes. It is presently used in diagnostics andmonitoring of gastrointestinal diseases, mainly in inflammatory bowel diseases.

In recent years a great interest in rehabilitation and physical activity amongst hemodialysed patients have developed. Despite having numerous exercise options, adverse effects of a lack of movement still are seen in this group of patients. The reasons of insufficient physical activity amongst hemodialysed patients are complications related to

Chronic Kidney Disease (CKD) is defined as abnormalities of kidney structure or function, present for >3 months, with implications for health. Amongst CKD complications the most fatal is cardiovascular disease, which together with Chronic Kidney Disease Mineral and Bone Disorder (CKD-MBD) share a possible origin in Wnt signaling pathway disturbances. Sclerostin, a potent Wnt signaling inhibitor may possibly be used as a potential new marker of exercise influence on vascular calcification and mineral and bone disorder in hemodialysed adults.
