There are about 9702 clinical studies being (or have been) conducted in Poland. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
There are experimental evidences of the importance of high intensity exercises in health outcomes improvement. However, there are limited knowledge about possibility to affect health outcomes in adolescents through exercises programs introduced into physical education (PE) lesson. Moreover, there is lack of the studies identifying people who do not respond to stimuli, as well as examining potential determinants of non-responsiveness. Thirdly, there are no studies examining the modification of exercise dose that should be reflected in the response in such individuals. Aim of this human experiment is to examine the effects of one cycle of 8-weeks high-intensity interval training (HIIT) implemented in physical education lesson on: (1) body composition (proportions of the body fat to the body muscles), (2) resting blood pressure, (3) physical efficiency. Study are conducted for two years (two cycles). Each year 300 students of two secondary schools, are involved in project: 15-16-year-olds in first year, 18-19-year-olds in second year. Students are divided in experimental groups -performing 8-weeks (twice a week) cycle of HIIT implemented into PE lesson, and the control groups - students following a typical PE programme. Each cycle consists of two parts. First part is related to the 8 weeks of HIIT training, while second part is related to the dose-expose study. All participants are examined during project before (Pre), after (Post) and Follow-Up intervention. Second part is planned after a break of several months. Persons who do not respond to the exercise stimulus in the first part will follow individually modified programmes. They will be measured before and after this additional training. To examine the assumed HIIT-induced changes in participants the investigators will apply: (1) anthropometric measurements: body height and weight, and BMI will be calculated, (2) body mass composition (fat and muscle mass), (3) resting blood pressure, (4) beep test which is field motor specific test to assess physical efficiency. The results of this project will help to answer the fundamental questions about HIIT induced morphological and physiological effects in adolescents, what is important from scientific and public health point of view. Particularly, in view of the growing pandemic of obesity, common elevated blood pressure and steadily declining physical fitness in children and adolescents.
The main aim of the research is to assess the impact of various forms of physical activity on body composition and posture. The basis of the research is the assessment of the current condition of people of different ages and the development of individualized physioprophylaxis programs for body posture and body weight abnormalities. In the senior group, the task of physioprophylactic programs is to prevent the loss of muscle mass, prevent falls and improve the quality of life.
Probiotics are "live microorganisms which when administered in adequate amounts confer a health benefit on the host". Accumulating evidence indicates their effect in mental health restoration. Beneficial neuropsychological and psychobiological effects are particularly well substantiated in clinical samples. However, it is not clearly documented whether probiotic supplementation reduces depressive and anxiety symptoms in healthy volunteers experiencing temporal deterioration in mental functioning while facing a stressful event. The combination of Lactobacillus helveticus R0052 and Bifidobacterium longum R0175 is particularly well studied in terms of its central nervous system action with significantly deciphered mechanism. As a result, this combination is particularly promising to study the effect of mental health improvement in healthy volunteers facing a stressful event. The aim of this project is to assess the impact of a 8-week supplementation with probiotic combination of Lactobacillus helveticus R0052 and Bifidobacterium longum R0175 strains in the daily dose of 3 × 10^9 colony forming units on mental health measures and oral microbiota composition and metabolome in healthy young adults facing a psychologically stressful event. The aim will be achieved by comparing the probiotic combination supplement to placebo in a randomized triple-blind controlled trial settings with a participant allocation ratio of 1:1. The summer academic examination session and the upcoming first take of the final exam in pharmacology at third year of medical studies will be a model of a stressful event. The participants will supplement their diets with probiotic/placebo for 8 weeks before the exam. After giving written informed consent, before the supplementation (relatively stress-free time period in terms of academic activities) the participants will provide background sociodemographic, anthropometric and psychometric data. At that time, participants will also give samples of saliva to assess cortisol and selected cytokines concentrations as well as salivary microbiome and metabolome. At the end of supplementation, a day before the final exam, participants will donate salivary samples and do psychometric tests for the second time to assess the same parameters as at the beginning of the study. Participants will also do a pre-exam test in pharmacology (not considered a formal academic assessment) as a comparator for the results of the formal examination held a day after.
Osteoporosis is a systemic condition characterized by low bone mass and altered bone tissue microarchitecture, with the resulting greater bone fragility leading to fractures. Osteoporosis develops as a result of genetic and environmental factors, with the patient's lifestyle playing an important role. Recent years saw an emergence of reports on the significance of the intestinal microbiota in the development of osteoporosis, thus new ways of modifying the composition and activity of microbiota have been sought, and the potential role of probiotics has been considered. Probiotics are defined as live microorganisms, which-when administered at appropriate doses-are beneficial to the host's health. Probiotics both modify the gut microbiota composition and directly affect the human body. Recently published clinical studies demonstrated that probiotics may facilitate osteoporosis treatment and prevention. The current randomized double-blind placebo-controlled study will assess the effect of a dietary intervention via oral supplementation of Lactobacillus plantarum and Lactobacillus paracasei in a population of Polish postmenopausal women on their bone mineral density assessed via bone densitometry-derived T-scores of the lumbar segment of the spine (L1-L4). Study subjects will take the provided probiotic formulation/placebo orally once daily for 12 months.
This Phase 2, randomized, double-blind, multicenter, induction and maintenance study is designed to evaluate the safety and efficacy of RVT-3101 in adult participants with moderate to severe active Crohn's disease.
The primary aim of this observational cohort study is to assess sports specialization, sports performance, history of injuries (prevalence, types, areas, duration) and quality of life in young healthy athletes aged 8-16 from Poland. Athlete profiles will be created based on the variables (explained in detailed description) examined. Furthermore, the investigators will perform one-year injury follow-up. The main questions it aims to answer are: - Do athletes with a specific profile (lower values in athletic performance tests, low values in quality of life) evaluated at one time point, suffer injury in the future in annual observation? - Do athletes with high sports specialization will sustain injury in one-year follow-up? - Does sports specialization have a relationship with sports performance tests, and quality of life? - Does sport specialisation, training volume, geographical factor relate to injury history? - Does sports specialisation, injury history differ between sports (individual and team sports)? - Does value of the specific muscle (lower limb) isometric strength will be associated with the dynamic balance scores in young healthy athletes?
The aim of the study is to evaluate simultaneously the immunological and clinical efficacy and tolerability of an influenza vaccine, inactivated, quadrivalent, with cleaved virus, in patients at risk for severe and complicated influenza routinely vaccinated against influenza in family medicine clinics or specialty clinics (pediatric, internal medicine, cardiology, gynecological diabetes, pregnant women, transplant).
The goal of this clinical trial is to compare del Nido and Bretschneider-HTK (HTK) cardioplegia solutions in patients undergoing elective aortic valve replacement. The main question it aims to answer is: • Does the del Nido cardioplegia provide better cardioprotection and clinical outcomes than HTK cardioplegia? Participants will receive one of the investigated cardioplegia solutions according to the randomization. Researchers will compare both groups in terms of cardioprotection (described as levels of CK-MB and hsTnI), in-hospital clinical outcomes, biochemical changes in coronary sinus blood and one-year follow-up.
Exposure of the human body to cold water triggers numerous beneficial physiological changes. The study aimed to assess the impact of regular winter swimming on blood morphological, rheological, and biochemical indicators and activity of antioxidant enzymes in males. The study includes winter swimmers and a control group. Blood samples were taken twice - before the start (November) of the winter swimming season and after its end (March). The average duration of ice water baths was 3-5 minutes, with a minimum frequency of once a week. The water temperature during the swimming did not exceed 10°C, approaching 0°C during the winter period.
