There are about 1447 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.
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.
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).
The study compares two medicines for treatment of children born small and who stay small, or with Turner Syndrome, Noonan Syndrome, or idiopathic short stature. The purpose of the study is to see how well treatment with somapacitan works compared to treatment with Norditropin®. Somapacitan is a new medicine, and Norditropin® is a medicine doctors can already prescribe in some countries. The study will last for about 3 years. The participants will either get somapacitan once a week for 3 years or Norditropin® once a day for 1 year followed by somapacitan once a week for 2 years. Which treatment the participants get is decided by chance.
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.
This is a multi-center, Phase IIa, randomized, double-blind, placebo-controlled study in patients with Alzheimer's Disease (AD).
The purpose of this study was to examine the efficacy of N-acetyl cysteine in the treatment of burning mouth syndrome. A control group of patients with burning mouth syndrome will receive a placebo. The effect of the therapy will be monitored with the help of the visual-analogue scale (VAS) and the oral health-related quality of life questionnaire (OHIP-14).
The research is planned as a prospective nested case-control study. The plan is to recruit about 1,200 consecutive subjects whose pharmacotherapy involves the drug(s) of interest within 4.5 years. The basic cohort - the subjects with the newly indicated indication for use: NOAC; platelet aggregation inhibitors from the P2Y12 receptor antagonist group; and HMG-CoA reductase inhibitors (statins); as monotherapy or without restriction with respect to any other concomitant pharmacotherapy. The ADRs will be analysed by CR by: age, gender, expectancy, severity, association, type (mechanism of event), and outcome, according to the classification of organ systems as well as association with the phenotype. Criteria for bleeding associated with the use of anticoagulant and antiplatelet therapy have been defined; as well as the myotoxicity and hepatotoxicity associated with statin therapy. Samples will be tested for biochemical, haematological, coagulation standard parameters and pharmacogenetic analyses of relevant genes depending on the used therapy. Pharmacogenetic analysis will be performed to genotype the polymorphisms of relevant pharmacogenes: Biological samples and clinical data will be anonymized plus all records of ADRs and other clinical variables will be protected. Possible drug-drug and drug-drug-gene interactions will be evaluated using the Clinical Decision Support System (CDSS) of Lexicomp, PharmGKB, the Flockhart Table, and other systems including panel consensus methods to determine the likelihood of an ADR being associated with drug interactions, and determine whether drug interactions contributed to the occurrence of ADRs to administered CV pharmacotherapy in subjects with variant pharmacogenes of interest (drug-drug-gene interaction). The overall project objective is to determine which pharmacogenes variants, together with clinical parameters, can be used as predictors of CV drug ADRs and are good candidates for inclusion in the clinical diagnostic panel for pre-emptive PGx testing.
The global coronavirus disease pandemic (COVID-19) has led to an increased need to wear protective equipment such as wearing face masks and practicing hygiene measures such as more frequent use of antiseptics. These measures can lead to changes in the skin, the development of new inflammatory skin diseases or exacerbation of existing ones, with health professionals especially under the risk of developing these changes. Changes in facial skin due to wearing masks have been observed in a number of studies, however, part of the study was based solely on subjects' self-assessment or clinical assessment, and only a small part on objective measurements of skin parameters. Also, the impact of prolonged masks' use have not been investigated. The aim of these study was to investigate the effects of constant, long-term use of protective masks on facial skin.
The global coronavirus disease pandemic (COVID-19) has led to an increased need to wear protective equipment such as wearing face masks and practicing hygiene measures such as more frequent use of antiseptics. These measures can lead to changes in the skin, the development of new inflammatory skin diseases or exacerbation of existing ones, with health professionals especially under the risk of developing these changes. Changes in the skin of the hands due to the use of antiseptics have been observed in a number of studies, however, part of the study was based solely on subjects' self-assessment or clinical assessment of researchers, and only a small part on objective measurements of skin parameters. Also, the impact of prolonged use of antiseptics and the impact of measures to prevent and protect against irritation such as topical application of emollient preparations have not been investigated. The impact of repeated use of antiseptics in the repeated exposure model on the forearms will be investigated. This model is a modification of the existing model of irritative dermatitis induced by sodium lauryl sulfate where the original irritant was replaced by an antiseptic solution.
