NCT ID: NCT06305611 Recruiting - Kawasaki Disease Clinical Trials

European and North Indian Cohort of KaWasaki dIsease

Start date: July 13, 2021
Phase:
Study type: Observational

Kawasaki disease (KD) is currently the leading cause of acquired heart diseases in children in developed countries. Cardiac involvement is the main determinant of the long-term prognosis of these patients, as coronary aneurisms (CAAs) may lead to ischemic heart disease and even sudden death. The current standard of care for KD has consistently reduced CAAs frequency from 25-30% to about 5%. Unfortunately, 10-20% of KD patients results resistant to standard treatment leading to a major risk of cardiac complications. Thus, scoring systems have been constructed in order to identify patients likely to be resistant to IVIG and who may benefit from more aggressive initial therapy. Different scoring scales developed by Kobayashi, Egami et Sano had shown a good sensitivity (77-86%) and specificity (67-86%) in predicting IVIG unresponsiveness in Japanese populations. However, their predictive value was not confirmed by subsequent studies in different ethnic populations. Recently, the French Kawanet group have proposed a IVIG unresponsiveness score that provided good sensitivity and acceptable specificity in a non-Asian KD population even if it was not subsequent validated by an external study. In our study population, the achievement of specificity and sensitivity values for both scores consistent with those reported by the original studies (sensitivity 70% and specificity 80% for Kobayashi and sensitivity 77% and specificity 60% for Kawanet), will be considered a success.

NCT ID: NCT06282003 Recruiting - Clinical trials for Well-Being, Psychological

Protective Anesthesiological Management Procedure Imposes Control on Respiratory Comlications

Start date: October 10, 2023
Phase: N/A
Study type: Interventional

Anesthetic effects, surgery, and invasive mechanical intubation can impair respiratory function during general anesthesia. The risk factors for postoperative pulmonary complications (PPCs) include the type of surgery and duration, ventilation-perfusion discrepancy, and the presence of pain. Mitigating PPCs under anesthesia is a goal, but effective strategies are yet to be defined. Conventional ventilation (CV) procedure uses more inspired oxygen during pre-oxygenation and anesthesia maintenance. The protective lung ventilation (PV) procedure, on the other hand, includes high positive end-expiratory pressure, lung recruitment maneuver, oxygen saturation levels above 94%, lower inspired oxygen levels, and continuous positive airway pressure before the tube is removed. In this study, 56 consecutive patients undergoing abdominal surgery were randomly assigned, with 30 in the CV and 23 in the PV group, while 3 were lost during the follow-up. We concluded that the implementation of protective lung ventilation strategies has the potential to reduce the occurrence of PPCs, recommending these strategies be adopted as the standard practice in general anesthesia.

NCT ID: NCT06275204 Recruiting - Gastric Cancer Clinical Trials

H. Pylori Screen-and-treat Study in a Population of Young Adults

Start date: March 4, 2024
Phase:
Study type: Observational

Gastric cancer remains a major challenge to public health on a global scale. H. pylori related cancer burden contributes to the largest proportion of cancer cases attributable to infections in Europe. Considering its absolute burden and persisting disparities, in addition to the substantial prevalence of H. pylori infection worldwide that is treatable, gastric cancer is a logical target for urgent action for prevention. Population-based H. pylori test-and-treat has therefore been proposed as a strategy for gastric cancer prevention. To fill the gaps in knowledge about gastric cancer prevention through H. pylori screening and eradication in younger adults, a study of a population-based H. pylori test-and-treat strategy in Ireland, Croatia, Latvia, Poland, Romania and Slovenia. Main goals of this study are to assess future program processes, feasibility, acceptability and effectiveness. In total of 6,800 adults aged 30-34 will be tested for H. pylori infection. They will be randomly selected to represent the chosen population and invited to participate in the study based on informed consent. Confirmed infections will be treated by available combined therapy in line with treatment guidelines and the success of eradication will be retested during a control check-up. Patients who will provide their consent to participate will undertake an interview about the risk factors in early childhood and their habits regarding alcohol consumption and use of tobacco. Compliance to testing and treatment, treatment results, adverse effects and reasons for dropping out will be additionally monitored. Gathered data will be analysed in alignment with our research questions. The investigators will disseminate reports and present the results to both the general public and the scientific community in order to foster future developments in gastric cancer prevention.

NCT ID: NCT06266065 Recruiting - Clinical trials for Coronary Artery Disease

Impact of Coronary Sinus Flow Reducer on Coronary Microcirculation and Myocardial Ischemia

Start date: February 27, 2024
Phase: N/A
Study type: Interventional

The increasing number of coronary revascularization procedures, coupled with improvements in drug therapy, has significantly extended the lifespan of patients with coronary artery disease (CAD). However, there remains a significant number of CAD patients who experience disability due to chronic refractory angina pectoris. These patients typically have severe diffuse CAD and are not candidates for further revascularization involving surgical coronary artery bypass grafting (CABG) or percutaneous coronary intervention (PCI). The installation of a coronary sinus reducer (CSR) represents a new option for percutaneous treatment of patients with refractory angina pectoris who are not suitable for surgical or percutaneous revascularization. The CSR device is designed as an hourglass-shaped stent that is positioned transcatheterally in the distal part of the coronary sinus. This increases intramyocardial venous pressure, which is believed to lead to a more favorable perfusion ratio between the ischemic subendocardial and non-ischemic subepicardial myocardium. Previous research has demonstrated that the implantation of CSR is a safe and relatively straightforward procedure. However, broader implementation and better patient selection are still limited by the fact that the exact mechanism of action remains controversial. It has not been determined why some patients have better outcomes compared to others with seemingly similar coronary artery disease. It is known that patients with atherosclerotic changes in the epicardial coronary arteries also have a certain degree of coronary microcirculation disease (the coronary vascular bed encompassing vessels with a diameter < 200 μm), which cannot be assessed through standard coronary angiography. This study aims to assess changes in coronary microcirculation after the implantation of CSR by measuring coronary flow reserve (CFR) and index of microcirculatory resistance (IMR) before and 6 months after the procedure. Furthermore, our goal is to associate these changes with clinical symptoms and myocardial ischemia.

NCT ID: NCT06236360 Recruiting - Metastatic Melanoma Clinical Trials

Metastatic Melanoma Patients on Immunotherapy With Nutritive Intervention Based on Mediterranean Diet

MINI-MD
Start date: December 21, 2023
Phase: N/A
Study type: Interventional

This research will study the effect of Mediterranean diet intervention in patients undergoing immunotherapy treatment for metastatic melanoma and its relationship with gut microbiome and quality of life. One group of patients will continue with their regular diet, while the other will receive dietary tele-intervention with trained nutritionist during the 12-week period. Gut microbiome, quality of life questionnaires, blood parameters and radiological examination will be evaluated before and 12-weeks after the start of the intervention.

NCT ID: NCT06192446 Recruiting - Clinical trials for Adherence, Treatment

Factors Influencing Adherence to Adjuvant Endocrine Therapy

Start date: September 20, 2021
Phase:
Study type: Observational

Breast cancer is the most common type of cancer and the leading cause of cancer death in women. Adjuvant endocrine therapy (AET) reduces the risk of disease recurrence and mortality in women with hormone-dependent breast cancer. This cross-sectional study aims to investigate adherence to AET and identify factors associated with adherence in the Republic of Croatia. The level of adherence, beliefs about medicines, and quality of life with AET will be investigated with validated instruments in the form of an anonymous survey. Given the available data on suboptimal adherence to AET in Europe and globally, it is clear that there is a need for investigating adherence in Croatia which hasn't been done so far. Each country, population, and health system has its own characteristics, and understanding the experience of using AET and identifying associated psychosocial factors could help in developing specific interventions supporting women and improving AET adherence.

NCT ID: NCT06189144 Recruiting - Contact Dermatitis Clinical Trials

Testing an Intervention in Irritative Contact Dermatitis

Start date: June 1, 2023
Phase: N/A
Study type: Interventional

An eczematous reaction is an inflammatory intolerance response of the skin. In acute phase the reaction is characterized by erythema and blistering while in the chronic phase it presents as dryness, itchiness and lichenification. Irritative contact dermatitis describes these patterns of reaction in response to toxicity of chemicals on the skin cells, which trigger inflammation by activation of the innate immune system.

NCT ID: NCT06184113 Recruiting - Clinical trials for Aortic Valve Replacement

Apixaban for the Prevention of Latent Biological Valve Thrombosis

Start date: December 2023
Phase: Phase 4
Study type: Interventional

Background: The optimal antithrombotic strategy early after aortic valve replacement surgery with a biological valve remains controversial due to lack of high-quality evidence. Either oral anticoagulants or acetylsalicylic acid should be considered for the first three months. Hypo-attenuated leaflet thickening on cardiac compute tomography has been associated with latent bioprosthetic valve thrombosis and may be prevented with anticoagulation. The investigators hypothesize that anticoagulation with apixaban is superior to single antiplatelet therapy with acetylsalicylic acid in reduction of hypo-attenuated leaflet thickening of bioprosthetic valves after aortic valve replacement. Methods: In this prospective, open-label, randomized trial patients without an indication for oral anticoagulation undergoing isolated aortic valve replacement surgery with novel rapid-deployment bioprosthetic valves will be randomized. The treatment group will receive 5 mg of apixaban twice a day for the first three months and 100 mg of acetylsalicylic acid thereafter. The control group will have 100 mg of acetylsalicylic acid once a day indefinitely. After the three-month treatment period a contrast enhanced electrocardiogram-gated cardiac computed tomography will be performed to identify hypo-attenuated leaflet thickening of the bioprosthetic valve. The primary objective of the study is to assess possible superiority of the treatment group in the prevention of hypo-attenuated leaflet thickening three months after randomization. Secondary objective is to assess possible noninferiority for safety of apixaban-based strategy when compared to acetylsalicylic acid at three months. Discussion: Antithrombotic therapy after aortic valve replacement surgery is used to prevent valve thrombosis and systemic thromboembolism. Latent bioprosthetic valve thrombosis is a precursor of clinically significant prosthetic valve dysfunction or thromboembolic event. The hallmark feature of latent bioprosthetic valve thrombosis is hypo-attenuated leaflet thickening on cardiac computed tomography. Subclinical leaflet thrombosis occurs frequently in bioprosthetic aortic valves, more commonly in transcatheter than in surgical valves. There is no evidence on the effect of direct oral anticoagulants on the incidence of hypo-attenuated leaflet thickening after surgical aortic valve replacement with rapid deployment bioprostheses.
