There are about 1437 clinical studies being (or have been) conducted in Croatia. 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.
Niacinamide in lower concentrations has been recognized as a cosmetic ingredient with hydrating properties. Therefore, aim was to test the efficacy and safety of niacinamide cosmetic preparation in A Randomized, Controlled Trial.
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.
The goal of this clinical trial is to compare two different, market approved, cryoballoon devices for the treatment of paroxysmal atrial fibrillation (AF). The main aims of the study are: - to compare the efficacy of two ablation devices (acute and 1 year success rates) - to compare the procedural characteristics (procedure duration, fluoroscopy duration, ablation time - to compare the complication rates Participants who have indication for cryoballoon ablation of AF will be randomized in 1:1 fashion to older fixed size cryoballoon and newer expandable cryoballoon. Standard of care cryoballoon procedure will be performed alongside with standard postprocedural follow-up. • to compare the complication rates Participants who have indication for cryoballoon ablation of AF will be randomized in 1:1 fashion to older fixed size cryoballoon and newer expandable cryoballoon.
This study is a first-in-human, prospective, multi-center, pre-market single-arm clinical trial to evaluate the Future Cardia™ ICM.
Endobronchial bleeding is a common complication of bronchoscopy. Major bleeding, although rare, can be life threatening and often requires advanced therapeutic interventional pulmonary procedures which are not widely available. Minor bleeding can negatively impact outcomes such as diagnostic yield, sample size and bronchoscopy duration. Both adrenaline and tranexamic acid are successfully used topically for hemostasis during diagnostic bronchoscopy. The aim of this study is to evaluate the efficacy of prophylactically applied adrenaline and tranexamic acid in bleeding prevention during diagnostic bronchoscopy.
Single Use Flexible bronchoscopes have gained popularity in recent years and are becoming technologically more advanced. They are widely accepted and used in everyday practice for simple procedures. The aim of this study is to evaluate single use flexible bronchoscopes in more advanced settings, such as interventional pulmonary procedures.
The purpose of this study is to assess the effect of Tranexamic Acid Oral Solution 5% in patients treated with direct oral anticoagulants or vitamin K antagonists and undergoing a single or multiple tooth extraction.
This study aimed to determine differences in functional recovery after total hip arthroplasty between a group of patients operated on using a direct lateral approach, an anterolateral minimally invasive approach, and a posterior approach to the hip joint. Arthroplasty is the most commonly performed surgical procedure in orthopedics and is also considered the gold standard for treating the final stage of osteoarthritis. There are several different approaches, but there are still conflicting studies that talk about the benefits of a particular approach. There is an insufficient number of scientific, prospective studies that monitor the basic functional and rehabilitation parameters, which are also indicators of the success of the performed procedure.
This is a study about the dynamics and effects of ultrasound guided maxillary nerve block in trigeminal neuralgia
Myrkl is advertised as a dietary supplement for use before alcohol consumption that is effective in prevention of side effects during the next day. With this research, the investigators want to determine the impact of the mentioned dietary supplement on the intestinal microbiome. For this purpose, the research was designed in three phases before, during and after the research as a double blind trial. In doing so, the subjects take a stool sample before and after the intervention and during the intervention, fill out questionnaires and undergo cognitive tests. At the same time, they give a blood sample after the intervention. After the results of the analysis are due, the researchers enter the data into the for that the predicted Access table (rel. representation of genera/genera/species, average results by questionnaires). The entered data is processed as part of statistical analysis.
