Clinical trials

The goal of this observational study is to learn whether high abdominal pressure or low blood flow pressure to the kidneys is linked to kidney injury after heart surgery. The main questions it aims to answer are: Does high abdominal pressure increase the risk of kidney injury after cardiac surgery? Can low blood flow pressure to the kidneys help predict who may develop kidney problems? Participants in this study are adults undergoing heart surgery, such as coronary artery bypass grafting (CABG) or valve surgery. Researchers will measure abdominal pressure and blood pressure continuously before and after surgery using medical devices that are already part of routine care. This study does not involve any changes to standard treatment. Participants will: Have their abdominal and blood pressures continuously monitored using existing devices Have blood and urine tests to check kidney function Be followed during their hospital stay and up to 30 days after surgery to assess outcomes like length of stay, readmission, and survival This study takes place at two hospitals-one in Poland and one in the United States. Researchers hope the findings will help identify early warning signs of kidney injury and improve monitoring practices after heart surgery.

Septic shock (SS) is a life-threatening condition resulting from excessive inflammatory response to bacterial, viral or/and fungal infections. It is associated with dysregulation of the immune system, activation of immune cells, and massive release of cytokines, commonly known as the cytokine storm (CS). The clinical manifestations of SS depend on the initial site of infection. However, the classic symptoms are associated with severe dysfunction of the respiratory and cardiovascular systems, which are observed from the early phase. Respiratory insufficiency frequently requires different forms of oxygen supplementation, including mechanical ventilation and even extracorporeal oxygenation. The severity of respiratory and other organ dysfunction depends on the inflammatory response to the infection and circulating toxins, which correspond to excessive cytokine release. In the past years, several studies documented that reduction of SS-related inflammatory response and CS improved organ function and alleviated the clinical course of SS. Unfortunately, an effective strong anti-inflammatory without side effects medications has not yet been found. Therefore, the use of natural anti-inflammatory and antioxidant substances seems very promising. Xanthohumol (Xn) is a natural prenylated chalcone extracted from the female inflorescences of hop cones (Humulus lupus) and possesses strong anti-inflammatory and antioxidant properties. It is widely used as a supplement to diet. Xanthohumol inhibits CS and has been showed to be an effective medication for reducing the severity of lung injury. It has been documented that Xn inhibits proinflammatory pathways in a different manner. A decrease in cytokine production and release can affect endothelial function and correct inflammatory-related vascular hyperpermeability, reducing uncontrolled water shift to extravascular space and then tissue edema. Clinical observation showed that administration of Xn alleviated clinical course, improved respiratory function, and reduced mortality in critically ill COVID-19 patients. Xanthohumol is safe and well tolerated by humans, and no adverse effects have been reported yet. Based on its strong anti-inflammatory and antioxidative properties, it can be speculated that the use of Xn can effectively reduce the inflammatory response and improve the clinical course in SS patients.

The EUmetriosis project aims to address the most important unmet needs of endometriosis sufferers to advance patient care. The objectives cover all main aspects of disease management, including elucidating the pathogenesis, diagnosing the condition promptly and efficiently, facilitating care by implementing self-management strategies, raising awareness and promoting policy changes. The objectives comprise individual yet intersecting pieces of a puzzle which, when positioned correctly, can immensely improve disease perception and understanding to enhance patient care. The project will prioritise the needs and wants of modern-day patients, focused on providing easily accessible and noninvasive therapeutic options. Combining all these elements in a well-coordinated project is pivotal to relieving the heavy burden endometriosis places on European society as a whole.

Adult patients after elective major abdominal surgeries who are planned to be admitted to the Intensive Care Unit (ICU) can be included in the trial. Each patient will be fed via the gastrointestinal tract. Half of the patients will receive enteral nutrition (EN) with additional fluids, and the rest will receive undiluted EN. The primary aim of this study is feeding intolerance assessment in both groups of patients.

Mastocytosis is very rare and highly heterogeneous group of disorders, characterized by the accumulation of clonal mast cells which can infiltrate several organs and tissues. Bones are the most frequent localization of systemic mastocytosis. The aim of our research was to explain the potential role of sclerostin in the pathogenesis of bone disease in mastocytosis.

Vulvodynia (Vd) is chronic functional vulvar pain, with prevalence of 3-16% and unclear etiopathology. Although Vd significantly deteriorates quality of life, the problem is marginalized, no pharmacologic treatment standards exist. Naltrexone hydrochloride is a specific opioid antagonist with slight agonist activity. There is growing body of evidence supporting the effectiveness of low-dose naltrexone (LDN) in different types of chronic pain. The main goal of this trial is to test the effect of LDN on pain perception and quality of life in women with different types of Vd. Half of the study population receives LDN and the remaining patients take placebo, according to randomization list. This RTC is quadruplet blinded.

The aim of this single-arm prospective, multicenter, cross-sectional study is to evaluate the nutritional status and body composition on tumor regression grade with bioelectrical impedance analysis in gastric cancer patients undergoing multimodal treatment. Results of this study will reveal whether nutritional status and body composition assessment based on bioelectrical impedance analysis will become a validated and objective tool to support clinical decisions in gastric cancer patients undergoing multimodal treatment.
