There are about 1246 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.
MISTRAL (Microbiome-based stratification of individuals at risk of HIV-1 acquisition, chronic clinical complications, antimicrobial drug resistance, and unresponsiveness to therapeutic HIV-1 vaccination) is a 5-year EU Horizon 2020 project, running from 1/1/2020 - 31/12/2024. The project is led by Fundacio Privada Institut de Recerca de la Sida-Caixa CAIXA in Barcelona and aims to explore the gut microbiota in relation to HIV-1, seeking microbiome biomarkers to support development of interventions that mitigate infection and enhance response to vaccines and therapies. If successful, MISTRAL will benefit millions of human beings living with, or at risk of acquiring HIV-1 infection, and will produce novel concepts and technical innovations applicable to other human diseases. By doing that, MISTRAL will help to unlock the full clinical potential of the human microbiome to stratify patient outcomes and will irreversibly bring microbiome science closer to clinical practice
This study will examine the effect of intraoperative sedation with midazolam, propofol and dexemdetomidine on the occurrence of postoperative cognitive impairment in patients undergoing surgical treatment of pertrochanteric fracture of the femur.
The study will monitor changes induced by orthodontic treatment and in the retention period, two years after the end of orthodontic treatment. The alignment of teeth, hygiene and gingiva will be assessed. Efficiency of two types of fixed appliances in active phase will be compared - esthetic and metal. Efficiency of two types of retention appliances in retention phase will be compared - fixed and removable. The benefits of orthodontic treatment to be studied are aesthetic concerns, dental self-confidence, self-esteem, social contacts, psychological influences, and chewing limitation. The stability of personality traits, body image and perfectionism will also be analyzed, as well as the extent to which these dimensions modify the reporting of psychosocial effects of malocclusion treatment.
Shoulder arthroscopy provides many benefits with a permanent increase in the possibilities and complexity of the application. A condition to perform it is intraoperative visual clarity dependent on hemorrhage control. The aim of this prospective, double blind, randomized, and controlled study is to examine the effect of intravenously administered tranexamic acid (TXA) on the visual clarity, perioperative hemorrhage, duration and early postoperative course of shoulder arthroscopy in beach chair position, which is not yet available in the literature. In the tested and control group, the investigators measure hemoglobin (Hb) in the waste irrigation fluid and the patient's blood before and after the procedure, visual clarity, duration of the procedure, postoperative shoulder swelling, pain level and analgesic drug consumption. The research uses scientific methods to determine if there is a reasonable basis for introducing TXA into routine clinical use.
Single center, open label randomized clinical trial. Study location: tertiary hospital center (University Hospital Split, Croatia). All COVID-19 patients with positive PCR test admitted to ICU and in need for respiratory support will be eligible for inclusion in this study. Patients admitted to ICU with severe COVID-19 disease and in need for invasive or non-invasive respiratory support with low levels of vitamin D (<50 nmol/l) measured on admission. All patients are older than 18 years and have confirmed COVID-19 disease with PCR test. Intervention: All patients included in this study will receive standard of care. Patients randomized into intervention group will be receiving 10 000 IU of cholecalciferol daily. Supplement will be administered orally or via gastric tube during ICU stay or for at least 14 days in case of ICU discharge before day 14. Supplementation will begin within 48 hours of admission to ICU. Supplement will be prepared and administered by experienced nursing staff. For patients receiving supplementation, vitamin D levels will be checked on days 7 and 14. In case that vitamin D levels are > 150 nmol/l or if the calcium levels are consistently > 2.6 mmol/l, further supplementation will be stopped. Outcomes: Primary outcome is number of days spent on ventilator. Secondary outcomes: all-cause mortality on day 28, all-cause mortality on day 60, mortality at hospital discharge, clinical improvement at day 28 (WHO clinical progression scale), days spent in ICU, days spent in hospital after discharge from ICU, need for dialysis at day 28, bacterial superinfections, neutrophile to lymphocyte ratio, disease severity (CRP levels, PaO2/FiO2 ratio, D-dimer levels, fibrinogen, ferritin, PCT), adverse outcomes. Hypothesis: patients receiving Vitamin D supplementation will have shorter number of days spent on mechanical ventilation.
The purpose of this study is to assess the performance and safety for the use of the investigational catheter for intracardiac mapping in the atria and ventricles.
Hypothesis: Patients with obstructive sleep apnea syndrome (OSAS) have cochlear receptor cells damage because of prolonged, recurrent hypoxia. The use of devices operating under the continous positive airway pressure (CPAP) leads to the recovery of cochlear receptor cells. Aims: 1. To determinate whether there is cochlear receptor cells damage in OSAS patients depending on the degree of the disease 2. Investigate whether the use of ventilation devices with continuous positive pressure and constant oxygen pressure in the airways can lead to the recovery of the cochlear receptor cells Participants and Methods: The investigation work will be designed as original scientific research- prospective cohort study at Department od Otorhinolaryngology and Head and Neck Surgery, University Hospital Center Osijek. The participants will be divided in two groups: target group with obstructive sleep apnea (n45) and control group with healthy individuals (n32). Research plan: All participating in this study will complete the following questionnaires: STOP- BANG and Epworth drowsiness scale. Subjects of the target group with moderate or severe obstructive sleep apnea will be referred to an otorhinolaryngologist audiologist for complete examination and processing after examination by a neurologist. These participants will be examined by an audiologist after 6-8 months of continuous and adequate use of the CPAP device for reevaluation. Participants of a control group will be patients examined or treated in Department of Otorhinolaryngology and Head and Neck surgery for other diseases in whom specific questionnaires excluded the existence of obstructive sleep apnea. Audiological diagnostics will be performed on all patients on the same devices of the Department of Audiology and Phoniatrics . Expected scientific contribution: To prove the existence of receptor hearing impairment in the patients with obstructive sleep apnea; and then to prove that the use of a of continuous positive airway pressure with constant oxygen pressure in patients with OSAS using CPAP devices leads to the recovery of the cochlear receptor cells whose damage occurred as a result prolonged recurrent hypoxia. In addition, to determine the importance of a broader diagnostic processing of patients with obstructive sleep apnea.
The objective of this randomized, placebo-controlled and crossover study is to extend the findings from the acute studies into more chronic administration of CBD in individuals with mild or moderate hypertension who are either untreated or receiving standard care therapy. The hypothesis is that the hypotensive effects of CBD will be apparent in both untreated and treated hypertension and reflected in improved vascular biomarkers and psychological well-being.
Self-Evaluation of Communication Experiences after Laryngectomy (SECEL) questionnaire has been developed, with the aim of evaluating rehabilitation needs and the psychosocial care for patients with laryngeal cancer. This short but comprehensive self-report instrument measures the perceived adjustment to communication experiences and is intended to aid in determining counselling needs in patients with laryngeal cancer who are treated with a laryngectomy. The first aim of this study is to evaluate the translation, psychometric properties and cultural adaptation of a Croatian version of the SECEL questionnaire. Secondary aim is to examine relationship between the Croatian version of the SECEL and the Short Form Health Survey (SF-36) and the Voice Handicap Index (VHI) questionnaires and to examine relationship between objective voice measures and Self-Evaluation of Communication Experiences after Laryngectomy (SECEL:HR).
This is a prospective, single-arm study conducted in University Hospital of Split, Department of Cardiology. Patients treated with PFA for symptomatic paroxysmal atrial fibrillation will be asked to participate in the study. An implantable loop recorder (ILR) will be placed immediately after the PFA procedure for rhythm monitoring. Early recurrences will be subsequently divided into very early recurrences (up to 1 month post-procedure) and early recurrences (1-3 months post-procedure). Late recurrences will be defined as those 3 to 12 months post-procedure. Patients will be monitored routinely through follow up visits during which ILR will be interrogated and eventual symptoms will be assessed. Follow-up visits will be scheduled 1, 3, 6, 12 months post-procedure. Median follow-up will be 12 months. Data for the study will be obtained from a loop monitor to assess the arrhythmia burden during follow-up visits in the University Hospital of Split Arrhythmia Clinic.
