Peripheral artery disease (PAD) is becoming a serious health problem of present times. It appears crucial to explore therapies that might help to restore blood flow or increase tissue oxygenation. The most effective methods of detecting early-stage changes in blood circulation in the extremities need to be identified. The aim of this study was to identify the effect of carbon dioxide (CO2) bathing on peripheral blood circulation measured by thermal imaging among patients with risk factors of PAD and ankle–brachial index (ABI) in the normal range or ABI indicating some or moderate arterial disease (ABI > 0.5). The correlation between surface temperature change and PAD-relevant characteristics was also examined. Forty-six patients who were over 65 years old who had a minimum of two additional PAD risk factors were recruited. A series of ten dry CO2 baths was performed. Thermal images were taken before and after the intervention. The CO2 therapy caused a significant change in the body surface temperature of many body areas. Numerous moderate correlations between temperature change and health-related characteristics were identified. Therefore, patients with PAD risk factors could benefit from CO2 therapy. Improvements in blood flow change the body surface temperature, and these changes could be successfully detected by thermal imaging.

Admission. Treatment of hip fractures is one of the most serious challenges for musculoskeletal traumatology, as these fractures occur mainly in the elderly. Despite the fact that modern traumatology has reached a high level, femoral neck fractures are still a very big problem among societies. The purpose of the study was an assessment of the level of platelets in patients 102 treated with surgery for a fracture of the neck of the femur. Material and method. The research was conducted in December 2019 in one of the trauma and orthopedic wards in Upper Silesia. The study included 35 patients aged 48-78 years treated surgically due to a hip fracture. All obtained data on patients come from medical records.Results. The analysis showed that 8 of the 35 patients included in the study had a decrease in the level of platelets 24 hours after the surgical treatment of a hip fracture. One week after the surgery, the level of platelets was normal. Conclusions.A relationship has been demonstrated between the level of platelets and surgical treatment of a fracture of the femoral neck. A significant drop in platelets was noticed in 23% of the subjects 24 hours after the surgery and their normal value was reached a week later. The problem requires further observation and research.

the aim of the study was to assess the effect of cold water immersion on changes in blood lactate concentration during post-exercise recovery in swimmers subjected to2-minute exercise test (front crawl swimming movements) using a VASA Swim Ergometer, with the maximum arm speed movements, as during the freestyle technique. the study covered 11 professional swimmers of the MKP Szczecin club, tested twice with a two-week interval. Each participant performed an exercise test twice, once with a passive recovery period, and the second time with cold water immersion after exercise, as a method potentially supporting the post-exercise recovery process. Each time before the test, immediately after and at 3, 6 and 9 minutes after exercise, the concentration of lactate in the capillary blood was measured. Statistical analysis of the obtained results showed that cold water immersion applied immediately after exercise resulted in a faster reduction of lactate concentration. the conducted research confirms that cold water immersion used in post-exercise recovery may be an effective method of restoring optimal physical fitness as part of the training process.
