There are about 1435 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.
Dental caries is a multifactorial disease primarily caused by supragingival dental biofilm. Its progression is influenced by many environmental factors, which include smoking. Tobacco heating systems (THS) are a novel tobacco product whose effect on the microbiome of the supragingival dental biofilm has not yet been investigated. The aim of the proposed research is to determine and compare the composition of the microbiomes of the supragingival dental biofilm of THS smokers, cigarette smokers, and nonsmokers using the Next Generation Sequencing method and to assess and compare the risk of new caries lesion formation between the test groups using the Cariogram method. The results of this research will provide insight into changes in the microbiome of the supragingival dental biofilm resulting from exposure to aerosols from tobacco combustion and tobacco heating.
Literature on the topic of athlete gut microbiota is scarce, and even more on the topic of its modulation. To address these issues a prospective cohort study was conceived. The cohort included young, male generally healthy professional athletes. The cohort will first be exposed to a course of sauerkraut supplementation as a synbiotic. Then the cohort will be observed without any intention for gut microbiota modulation. Before and after each study phase a gut microbiota analysis will be performed for its parameters. The aim of this study is to assess whether the intervention leads to significant changes in the gut microbiota parameters in all subjects and if yes what the signal of the intervention was, meaning whether the changes were consistent among all subjects regarding the analyzed parameter and its direction of effect. The results will be compared with data from earlier research on gut microbiota modulation in professional athletes with soluble fiber as prebiotics and a placebo. The study will provide valuable data on the athlete gut microbiota and its potential modulation.
In this observational cross-sectional study " the clinical characteristics of adenoid vegetations in adulthood will be investigated.
Bone healing after tooth extraction may be affected by defects in the buccal wall of the alveolus, such as fenestrations and dehiscences. Therefore, it is advisable to perform a surgical procedure such as guided bone regeneration after tooth extractions. Different biomaterials are used for this purpose. The aim of this study is to investigate the qualitative and quantitative histological changes in human biopsies taken after 6 months of healing of extraction sockets with buccal wall defects. For this purpose, the defects of 36 patients (18 per group) will be augmented with injectable biphasic calcium phosphate (I-BCP) or bovine xenograft (BX) after extraction. After six months of healing, bone biopsies will be taken and processed to the qualitative and quantitative histological analysis.
This is a study about the dynamics and effects of different types of blocks (intraoral conduction anesthesia of the alveolar nerve and extraoral US block of the mandibular nerve) for extraction of lower third molars.
The purpose of this study is to assess the performance and safety of using the investigational catheter.
single-centre randomised prospective trial will conducted at the University Hospital of Split in Croatia. The investigators plan to enrol 100 patients, randomly assigned to suture-based wound closure (n=50) or tissue adhesive-based wound closure (n=50) with two-component skin adhesive Glubran Tiss 2®. The neurological outcomes will assessed postoperatively during the follow-up period at intervals of 2, 6, and 12 weeks respectively.
The aim was to test the difference in glycemic variability after meal consumption during intermittent fasting and the usual diet.
The aim of this study was to measure whether the flow rate through the brachial artery and inflammatory markers were associated with the development of tissue edema in the surgical intensive care unit patients.
The aim was to compare placental oxygenation in low risk, uncompli-cated, term pregnancies measured by near-infrared spectroscopy (NIRS) in relation to the placental maturity grade determined by ultrasound assessment according to Grannum scale. The study included 34 singleton subjects divided into two groups accord-ing to placental maturation: low grade (Grannum 0-1; n=10) and high grade (Gran-num 2-3; n=24). In each study subjects, measurement was performed at two sites: (a) test site above the central part of the placenta, and (b) control site out of placenta on lower abdomen, in medial line, 3 cm from the symphysis. Student's t-test was used to compare tissue oxygenation index (TOI) values among the study groups. The normality of distribution was demonstrated by the Kolmogorov-Smirnov test.
