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.
Chronic inflammation in polycystic ovary syndrome (PCOS) may be the result of dysregulation of cytokine production (due to insulin resistance, excess visceral fat and hyperandrogenemia), i.e., overproduction of pro-inflammatory factors (e.g. TNF, IL-1, IL-6) in relation to anti-inflammatory ones (IL-10). This condition may be an important link between obesity and insulin resistance, which is crucial in the etiopathogenesis of the syndrome. However, it is not known whether it results from the tendency to accumulate adipose tissue or is a feature of the syndrome itself. There is no data indicating the relationship between chronic inflammation and the severity of metabolic disorders and the value of ovarian reserve in women with various PCOS phenotypes.
Fibromyalgia is a syndrome characterized by chronic, generalized pain in muscles and joints with the presence of characteristic, symmetrically occurring so-called "tender points" - areas of the body that are excessively sensitive to pressure. The condition is associated with a feeling of chronic fatigue, mood and sleep disturbances and a sensation of body stiffness. These complaints are bothersome and significantly impair patients' functioning in every aspect of their lives. There are few studies evaluating the functioning and disability of people with fibromyalgia. No such study has been conducted in Poland to date. Therefore, the purpose of this study is to evaluate the functioning and disability of fibromyalgia patients and the relationship of the level of disability with selected factors, such as pain intensity, emotional state, sleep quality, etc.
Background: Spinal metastatic disease constitute a serious clinical problem in oncology. Bones are the third most common organ where metastases are located, and the spine is the place where they are most often located. Due to the complexity of the clinical problem, metastatic spine disease remains of interest to many medical specialties: neurosurgery, orthopedics, clinical oncology, radiotherapy and rehabilitation. With the development of modern diagnostic methods and wider access to them, the demand for neurosurgical treatment in this group of patients is growing. Surgical treatment is undertaken in cases of spinal cord compression, instability, spinal deformation or pain that is resistant to radiotherapy. The standard treatment in most cases is posterior instrumentation of the spine using titanium pedicle screws. Unfortunately, these systems cause numerous artifacts in diagnostic imaging, both in CT and MRI. These distortions make it difficult to plan radiotherapy and determine the optimal dose that would avoid healthy tissues. Moreover, artifacts could make difficult postoperative follow-ups aimed at assessing local recurrence. The solution to these problems is the use of radiolucent implants. There are systems based on carbon fibers embedded in PEEK which do not cause typical artifacts for titanium implants. Study plan: The open, three-arm, prospective randomized study is planned to involve 226 patients with metastatic disease of the spine, with a known or undiagnosed primary site. Patients will be qualified for 2 types of interventions. The first one includes treatment with stereotactic radiotherapy (SBRT) in the first stage of treatment and early instrumentation of the spine with titanium implants. The second type of intervention includes patients qualified for surgical treatment using spine stabilization and postoperative SBRT. Patients within this arm will be randomized into two groups differing in the type of material the instrumentation is made of: carbon-PEEK or titanium. The study group will be patients stabilized with carbon implants, and the control group will be those who will have titanium implants. Study population: The study includes adult patients with metastatic spine disease, with a known or unknown primary tumor, qualified for SBRT and surgical treatment. Assumed effects: It is assumed that the treatment proposed in the project would extend progression free survival by several months or achieve local control in an additional 5% of patients. Moreover, by improving the quality of imaging, earlier diagnosis of local recurrences and implementation of appropriate locoregional treatment would be possible.
The purpose of this study is to evaluate the efficacy of lepodisiran in reducing cardiovascular risk in participants with high lipoprotein(a) who have cardiovascular disease or are at risk of a heart attack or stroke. The study drug will be administered subcutaneously (SC) (under the skin).
This is an open, multicentric, interventional, prospective, non-randomized clinical investigation. The first aim of the study is to confirm that MammoWave reaches sensitivity>75% and specificity>90% in breast cancer (BC) detection on 10.000 volunteers undergoing regular screening programs.
The primary objective of this study to evaluate the efficacy of ravulizumab compared with placebo to reduce proteinuria and slow the rate of eGFR decline in adult participants with IgAN who are at risk of disease progression.
The aim of this study is to compare two distinct modes of NIM Vital application in thyroid surgery: NerveTrend vs. NerveAssure mode with respect to prevalence of early postoperative RLN injury. The hypothesis explored in this study is that NerveTrend mode may be not inferior than NerveAssure mode in intraoperative identification of impending neural injury and in prognostication of postoperative glottis function in monitored bilateral thyroid surgery. Hence, NerveTrend mode may be considered a bridge between i-IONM and NerveAssure modes, and particularly in health care environments with limited financial resources it can be considered a substantial step forward representing a modern alternative to the NerveAssure technique. A prospective, randomized study with 2 arms: NeveTrend vs. NerveAssure mode (n=132 patients and 264 nerves at risk, each). The primary outcome measure is prevalence of recurrent laryngeal nerve (RLN) injury (%) on postoperative day 1 assessed by direct laryngoscopy.
Lower Silesia Sinus Reducer Registry is a , single-center, single-arm registry including patients with chronic disabling refractory angina pectoris (Canadian Cardiovascular Society [CCS] classes 2-4) despite maximally tolerated anti-angina medical therapy who underwent Coronary Sinus Reducer implantation .
This study is conducted to support a 2-dose series (1+1 vaccination schedule) for immunization of individuals from 6 months of age. The study is designed to evaluate the non-inferiority of the immunological response of MenACYW conjugate vaccine to Nimenrix® after the completion of the 2-dose series (1+1 vaccination schedule), with the first dose (priming dose) being given at 6-7 months of age to MenACWY- naïve healthy infants and the second dose (booster dose) given at 12-13 months of age. This study will also describe additional immunogenicity parameters and safety of MenACYW conjugate vaccine and Nimenrix® in the same population of participants.
The study aimed to evaluate the outcomes of bifurcation PCI using two techniques (Culotte vs. DK-Culotte) using data from a retrospective analysis.
