There are about 960 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.
To contribute to improving the level of functioning and quality of life and mental health outcomes for people with severe and enduring mental ill health (SMI) (schizophrenia, bipolar disorder, depression) by adapting and up scaling the implementation of a community‐based service delivery model in Croatia.
Spinal anesthesia blocks acute pain in older patients with femur fracture. Delirium is a common complication seen after femur fracture, affecting approximately 10-16% of patients. It is associated with increased mortality at 1st year, delayed rehabilitation efforts, prolonged length of hospital stay, poorer functional outcomes, and increased risk of nursing home placement. Intrathecal dexamethasone administration improves quality of anesthesia in patients with femur fracture compared to conventional spinal anesthesia.
Cardiovascular disease increases the risk of depression and vice versa. Many cardiovascular patients are subjected to percutaneous coronary intervention (PCI). Potential biomarkers for the development, the course and the recovery of both diseases are in the focus of interest of many studies. One of the biomarkers that stands out is brain derived neurotrophic factor (BDFN). BDNF plays a significant role in regulating vascular growth and repair but also stimulates the survival, differentiation, and conservation of neurons. The aim of the study is to detect the depression in patients undergoing PCI and to determine the impact of psychiatric treatment on the functional recovery and on the changes of BDNF.
The primary objective of the study is to determine the effectiveness of nutrition education (individual and group) on the intensity of pain in patients suffering from chronic pain. The secondary goal is to determine whether there is a change in the status of the patient's nutrition, their quality of life, quality of life, and other indicators of the psychophysical condition of the patient.
The aim of the recovery protocol is to reduce surgical trauma, postoperative pain, and complications, shorten hospital treatment and improve postoperative recovery. Orthopedic and traumatology surgeries are often followed by a long-lasting recovery with difficulties of everyday functioning. Up to this time, only a few publications of multidisciplinary protocol in orthopedics and traumatology have been published, mostly to improve the care of patients after elective surgical procedures. The goal of multidisciplinary after surgery recovery program in orthopedics and traumatology is to improve the care of both urgent and elective patients using standardized, multi-professional care programs. It focuses on patient education, preoperative respiratory training, adequate nutritive and hemodynamic support, modified anesthesia protocol, prevention of postoperative pain, nausea and vomiting, and early postoperative delirium detection. The implementation of the program will reduce the rate of postoperative complications and the rate of rehospitalization, enhance the recovery after surgery and increase the satisfaction with the treatment.
The administration of the tranexamic acid (TRAXA), an antifibrinolytic, blocks primary fibrinolysis, and thus the haemorrhage, in the early postoperative period. Significant surgical operations, as well as trauma, initiate a similar dynamic homeostatic mechanism between the creation of a clot (primary and secondary haemostasis) and its dissolution (fibrinolysis). Antifibrinolytics have been proven effective in reducing haemorrhage in patients who have undergone significant surgical operations with normal fibrinolysis, with the use of an appropriate surgical technique. A pharmacokinetic study has shown that peak fibrinolytic activity is present for 6 hours after the incision and it persists for 18 hours in total knee and hip arthroplasty. The administration of the tranexamic acid in optional orthopaedic surgery of total hip (THA) and knee (TKA) arthroplasty reduces the postoperative haemorrhage, as well as the number and volume of the postoperative autologous blood. A trauma in the organism triggers the immunologic response. New term has been introduced - the post-traumatic immunosuppression (PTI), characterised by: a change on the immunologic cells (neutrophilia, monocytosis, increased number of mesenchymal stromal cells, reduced expression of HLA-DR on monocytes, reduced function of natural killer (NK) cells, increased lymphocyte apoptosis, a shift in homoeostasis towards the Th2 phenotype facilitated by Treg lymphocytes - CD4+CD25+CD127-); a change in production levels of various cytokines (anti-inflammatory cytokines): IL-10, IL-4; anti- and pro-inflammatory cytokine: IL-6; pro-inflammatory cytokines IL-2, TNF-α, IFN-γ); the activation of the complement system (C5a and C3a via factor VII - tissue factor system, activated by cell damage). Post-traumatic immunosuppression can be made worse by transfusion, haemorrhage, stress, significant surgical operation and immunosuppressive drugs. The research has shown that Treg lymphocytes CD4+CD25+CD127- have an important role in controlling the acquired and innate immunity (comprising 6-8% of all CD4+ lymphocytes). Stopping haemorrhage prevents the occurrence of anaemia, as well as the need for transfusion of blood products, which lead to developing the post-traumatic immunosuppression (PTI).
Saint John's wort (Hypericum perforatum) was recognised as a traditional, folk medicine used topically for the treatment of wounds, abrasions, burns, sunburns and inflammatory skin disorders. Its use in wound healing could be justified with its anti-inflammatory, antimicrobial and astringent effects. It also stimulated tissue growth and cell differentiation, as one of Hypericum perforatum's main ingredients, hyperforin, was shown to activate TRPC6 channel which had been recognised as an activator of keratinocyte differentiation. Another potentially useful activities could be its inhibitory effects on epidermal Langerhans cells. Furthermore, in vivo research showed its potential with improved wound healing in different rat models. Finally, several clinical studies were performed testing its effects in atopic dermatitis treatment, wound healing after caesarean section and episiotomy, as well as healing of post-surgical scalp wounds, bed sores and venous ulcers. The aim of the study will be to determine the effectiveness of ointment containing Hypericum perforatum oil on promoting skin recovery in different human skin damage models on healthy volunteers, in comparison to placebo. Chosen test sites will be the forearms. One forearm will be treated will the formulation containing Hypericum perforatum oil while the other will be treated with the placebo formulation. Four test sites will be marked on each forearm with skin barrier damage induced on three areas while the fourth will be left intact. Treated forearm and test sites sequence on forearms will be prospectively randomized (double randomization). First skin damage model used in the trial will be sodium lauryl sulphate (SLS) induced irritation. The SLS solution will be placed on the skin of participants under the occlusion for 24 hours. Second model will be the tape-stripping procedure with defined TEWL value set as an endpoint. The final model will be damage by the UV radiation. UV irradiation will be performed under strict conditions with use of the necessary safety equipment. Only the defined test areas will be irradiated with the defined dose of radiation.
Sustained, monomorphic ventricular tachycardia (VT) is most commonly encountered in patients with structural heart disease, usually with ischemic aetiology. It has been proven that repeated episodes of sustained VT contribute to the mortality of patients with structural heart disease. These patients are usually implanted with implantable cardioverter defibrillator without (ICD) or with cardiac resynchronisation therapy (CRT-D). According to the current guidelines 3D mapping with radiofrequency (RF) ablation of the tachycardia substrate is an established therapeutic option. As part of the clinical follow-up of patients implanted with cardiac implantable electronic devices (CIED), CIED function parameters are monitored every 6 months, which is always done before and after any procedure involving RF ablation. Furthermore, a transient drop of R wave sensing has been demonstrated after the atrioventricular (AV) node ablation in patients with single-chamber pacemakers and fast atrial fibrillation. The aim of this study is to assess the change in R wave sensing after the RF ablation of VT substrate. This study will be performed as a clinical, prospective, multi-centre, observational cohort study with a structured follow-up period of 12 months. All consecutive patients with sustained VT implanted with ICD or CRT-D undergoing RF ablation procedure of myocardial substrate, who are able to understand and sign informed consent, will be enrolled. Primary objective is a R wave sensing drop > 30% after VT substrate ablation procedure. Recruiting should not exceed 12 months with the minimal follow-up period of 12 months (24 months in total). Standardized statistical methods and test will be done using SPSS Software Version 22.0 or newer. This unique study offers the possibility to show the impact of RF ablation on short-term and long-term R wave sensing change assessed by ICD or CRT-D's ventricle electrode in patients with sustained VT and structural heart disease undergoing ablation procedure. This observational data is needed to further refine the treatment of these patients and to prevent possible ICD/CRT-D dysfunction which could endanger this patient population.
Patients with multiple sclerosis (MS) struggle on a daily basis with accompanying, "Invisible" symptoms like primary fatigue, pain and emotional-cognitive disorders. With the disease progression, these symptoms only intensify, and in combination with basic physical symptoms, quality of life (QOL) rapidly decreases. An important goal of researchers and clinicians involves improving the QOL of individuals with MS, and the exercise therapy represents potentially modifiable behavior that positively impacts on pathogenesis of MS and these "Invisible" symptoms, thus improving the QOL. However, the main barrier for its application is low motivational level that MS patients experience due to fatigue with adjacent reduced exercise tolerability and mobility, and muscle weakness. Getting individuals with MS motivated to engage in continuous physical activity may be particularly difficult and challenging, especially those with severe disability or Expanded Disability Status Scale (EDSS 6-8). Till now, researchers have focused their attention mainly on the moderate or vigorous intensity of exercise and on cardiorespiratory training in MS patients to achieve improvements in daily life quality, less indicating the exercise content, and most importantly, breathing exercises. In addition, it is investigators intention to make exercise for MS patients more applicable and accessible, motivational and easier, but most important, productive. Investigators think that MS patients experience more stress with aerobic exercise or moderate to high intensity program exercise, and can hardly keep continuum including endurance exercise, or treadmill. Hypothesis: Investigators hypothesis is that 8-weeks of continuous low demanding or mild exercise program with the accent on breathing exercise can attenuate primary fatigue, pain, headaches, emotional-cognitive and sleep dysfunctions in MS patients and provide maintenance of exercise motivation. Investigators also propose that important assistant factor for final goal achievement is social and mental support of the exercise group (EDSS from 0-8) led by a physiotherapist. This will help to maintain exercise motivation and finally make better psychophysical functioning, and thus better QOL.
