Many Polish patients do not inform physicians about supplements they use in addition to prescribed medicines. This may be because they consider dietary supplements as being rather natural products that cannot cause health problems. Although dietary supplements may produce side effects, Poland's food safety system and medical statistics do not recognise the necessity of reporting such cases. However, a different approach is observed in France and the United States where adverse effects of food supplements as well as drugs are reported. The aim of this study was to determine the need for creating in Poland a general model of a register monitoring dietary supplements and their adverse effects. In order to achieve this goal, a detailed comparison between the American and European monitoring systems was made. It showed the relationship between negative symptoms caused by specific components in supplements and t profiles of patients who reported side effects. Additionally, it was found that there is a real risk associated with side effects caused by dietary supplements. Therefore, it necessary to establish in Poland a special system for recording such cases as it should be beneficial to patients, including polypragmatic patients.

Objectives : Rugby is sport with a high risk of injury. Repeated changes in exercise intensity and the high training intensity may cause to overuse injuries and long-term disability. The aim of the study was to analyze the prevalence of injuries during trainings and forms of rehabilitation procedures performed after their occurrence among elite and sub-elite rugby players. Methods : The data was obtained from 60 professional rugby males from France and Poland. Data were collected using paper-based recording form. It was a specially designed questionnaire which concerned specific details of the injury, including body location, type of injury, treatment and number of days off lost from playing rugby and on forms of rehabilitation procedures performed after their occurrence among elite and sub-elite rugby players. Results : During the study period, the overall incidence rate for injury suggested a 1.04 times more often injury occurrence (IRR = 1.04, 95% CI: 0.08; 2.00) among Polish players compared with French players; however, the distribution of injuries varied by country. The training injury incidence (TII) and incidence proportion (IP) were also higher in Poland than in France ( p < 0.05) with the sprain as the most frequent type of injury in all rugby players. France was 7.8 times (IRR = 7.88, 95% CI: 1.29; 3.21) more likely to sustain a fracture than Poland, which much often experienced less serious injuries (bruise, rapture of muscle and ligament) (IRR = 3.02, 95% CI: 2.06; 3.98). Polish players were provided with various forms of physiotherapy while Franch players often worked with a physiotherapist with a therapeutic method ( p < 0.005). Poland and France reported experiencing side effects after an injury and the most frequent was pain. In their opinions, the reasons influencing the effectiveness of rehabilitation are too quick return to the game and too short time of rehabilitation. Conclusions : The competitive level of the rugby player influences not only the frequency and type of injury occurrence, but also access to the different forms of rehabilitation. Nonetheless, the side effects occurring after injury and the causes of ineffective rehabilitation are still similar. Further studies are needed to gather significant data to accurately formulate future injury prevention protocols or recommend modifications to game laws or competition formats, aiming at players' welfare.
