There are about 9594 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.
The participants in the study will be adult patients with suspected sleep-disordered breathing. A one-night polysomnography will be performed using the NOXA1 device (NOX Medical, Reykjavík, Iceland). During the polysomnographic examination, sleep, breathing, heart rate and activity of the masticatory muscles will be recorded. Blood sample will be taken from each of the participants qualified to the study and control group to determine the level of dopamine and used to perform genetic tests of selected single nucleotide polymorphisms occurring within the genes regulating the concentration of dopamine and genes encoding dopamine receptors.
The goal of this retrospective chart review is to obtain clinical safety and performance data for the GamCath HighFlow Dolphin Protect Catheter in patients with acute kidney injury, acute renal failure, or chronic kidney disease. The main questions to answer are: 1. Duration of catheter use (survival) 2. Reason(s) for catheter removal
Postoperative delirium (POD) and postoperative neuropsychological dysfunction are frequently noted in critically ill patients undergoing elective or emergency surgery and treated in the intensive care unit (ICU). Delirium is a serious complication that prolongs hospital stay and contributes to poor outcomes and increased risk of death. The pathomechanisms of delirium are still not very well recognized and there are several theories that seem to explain it. The most important pathomechanisms of delirium are associated with cerebral ischaemia, disorders in acetylcholinergic system, disorders in neuronal plasticity and oxidative stress. Cerebrolysin, a mixture of various peptides obtained from the structural proteins of the pig's brain, possesses strong antioxidative and neuronal protective properties. Cerebrolysin is recommended to treat patients with dementia, after cerebral ischemia and after brain trauma. It has been documented that Cerebrolysin reduces the severity of secondary brain damage after ischemia, improving neuronal plasticity and then cognitive function, and reducing severity of oxidative stress. Based on these properties it can be speculated that Cerebrolysin may reduce the risk of postoperative delirium in patients undergoing elective surgery, which are associated with a high risk of postoperative delirium.
Aim of the study is to determine the presence and direction of electrocardiographical changes of cardiac repolarization after thoracic paravertebral block, depending on block laterality. Injection of local anaesthetic into paravertebral space (paravertebral block, PVB) temporarily impairs transmission in nerve fibers in proximity of the deposition site. In case of PVB covering the rami of upper thoracic spinal nerves, among the others thoracic sympathetic cardiac nerves are blocked, possibly affecting action potential time of heart, especially the repolarization, and the related electrocardiographic phenomena. The risk of life-threatening polymorphic ventricular tachycardia (torsade des pointes, TdP) is associated with certain electrocardiographical symptoms, like QT interval prolongation and increased transmural repolarization dispersion (TDR). Determining the presence and direction of cardiac repolarization changes after a thoracic PVB will allow to conclude about its impact on TdP risk: protective or, contrary, arrhythmogenic.
The goal of this cross-sectional study is to learn about the level of knowledge and attitudes of medical staff working in dialysis centers about living kidney donations. The main questions it aims to answer are: - What is the level of knowledge of dialysis center medical staff regarding living kidney transplantations? - How much time does the staff have for educating the patients about living kidney donations? Participants will be asked to answer a self-report questionnaire along with two standardized tools.
The goal of this prospective observational cohort stuty is to assess the prevalence of overlap irritable bowel syndrome on coeliac disease in patients on gluten-free diet. The main questions it aims to answer are: - percentage of the occurrence of irritable bowel syndrome in the population of Polish patients with celiac disease on restrictive gluten-free diet - what is the correlation between the persistence of intestinal symptoms and adherence to a gluten-free diet (according to the patient's assessment) or confirmation of disease remission (based on histopathology or antibody level).
This study will evaluate the long term safety, tolerability, PK, and efficacy of XEN1101 25 mg QD taken orally in subjects with Focal Onset Seizures (FOS) or Primary Generalized Tonic-Clonic Seizures (PGTCS) for the treatment of seizures for up to 3 years.
A migraine is a moderate to severe headache on one side of the head. A migraine attack is a headache that may be accompanied by throbbing, nausea, vomiting, sensitivity to light and sound, or other symptoms. A number of treatments are available for adults with migraine but there are limited approved treatments available for participants less than 18 years of age. The main goal of the study is to evaluate the long-term safety and tolerability of atogepant in pediatric participants between the ages of 6 and 17 with episodic migraine. Atogepant is a medicine currently approved to treat adults with episodic migraine (0 to 14 migraine days per month) and is being studied in pediatric participants between the ages of 6 and 17 with a history of episodic migraine. This is a Phase 3, open-label study of atogepant in participants with a history of episodic migraine. Participants must have completed participation in another study of atogepant (lead-in study) or completed the screening period of that study. Participants must have 4 to 14 migraine days and less than 15 headache days in the 4-week screening electronic diary (eDiary; similar to a smart phone). Around 250 participants will be enrolled in the study at approximately 100 sites worldwide. Atogepant is a tablet taken once a day by mouth. Participants between the ages of 12 and 17 will receive high dose atogepant for 52 Weeks. Participants between the ages of 6 and 11 will receive an atogepant dose determined in the lead-in study for 52 Weeks. There may be a bigger responsibility for participants in this study. Participants will attend regular visits during the study at a hospital or clinic. The effects of treatment will be checked by medical assessments, blood tests, checking for side effects, and completing questionnaires.
Prospective, multicenter, randomized, sham-controlled, double blinded, adaptive study designed to evaluate the safety and efficacy of a percutaneously created interatrial shunt using the Alleviant ALV1 System in patients with HFpEF/HFmrEF.
The aim of the study is to asses safety and indications and contraindications for performing bronchofiberocopy (FB) with respiratory support methods, i.e. non-invasive ventilation (NIV) and high flow nasal oxygen therapy (HFNO). Additionally, researchers want to determine how using these methods could avoid the risk of most common complications such as: hypoxemia-related events, decompensation of chronic respiratory failure, worsening of gas exchange, hemodynamic instability.
