There are about 1129 clinical studies being (or have been) conducted in Estonia. 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.
The aim of this study is to evaluate the long-term (5-year follow-up) results of laparoscopic gastric sleeve (LGS) in terms of weight loss and obesity related comorbidities, as well as the risk factors associated with postoperative nutritional deficiencies.
The investigators are collecting genetic information through blood samples as well as clinical and EEG data from over 1000 people with Juvenile Myoclonic Epilepsy (JME) across the UK, Europe and North America. This study will draw on both existing and new samples from JME patients. These will be compared to anonymised data from samples for 2000 controls. The goal of this study is to find the genetic cause of JME. Finding the cause will help create better treatments for JME, as well as improve patient outcomes by allowing us to detect it earlier.
Stroke is a leading causes of death and disability. At least 20% of strokes occur during sleep, so- called 'wake up stroke'. Thrombolysis with the clot-busting drug alteplase is effective for acute ischaemic stroke, provided that it is given within 4.5 hours of symptom onset. Patients with wake-up stroke are currently ineligible for clot-busting therapy. Previous studies indicate that many wake-up strokes occur just before awakening. In this study, patients with wake-up stroke will be randomized to thrombolysis with tenecteplase and best standard treatment or to best standard treatment without thrombolysis. Tenecteplase has several potential advantages over alteplase, including very rapid action and that it can be given as a single injection. Prior to thrombolysis, a brain scan must be done to exclude bleeding or significant brain damage as a result from the stroke. We will use a CT scan to inform this decision. CT is used as a routine examination in all stroke patients. Other studies testing clot-busting treatment in wake-up stroke are using alteplase and more complex brain scans, which are not routinely available in the emergency situation in all hospitals.
Neonatal hypoxic-ischemic encephalopathy (HIE) is a major cause of death or long-term disability in infants born at term in the western world, affecting about 1-4 per 1.000 life births and consequently about 5-20.000 infants per year in Europe. Hypothermic treatment became the only established therapy to improve outcome after perinatal hypoxic-ischemic insults. Despite hypothermia and neonatal intensive care, 45-50% of affected children die or suffer from long-term neurodevelopmental impairment. Additional neuroprotective interventions, beside hypothermia, are warranted to further improve their outcome. Allopurinol is a xanthine oxidase inhibitor and reduces the production of oxygen radicals and brain damage in experimental, animal, and early human studies of ischemia and reperfusion. This project aims to evaluate the efficacy and safety of allopurinol administered immediately after birth to near-term infants with HIE in addition to hypothermic treatment.
The purpose of this study is to evaluate the effect of deepening of sedation on intra-abdominal pressure in mechanically ventilated adult patients with intra-abdominal hypertension.
SPECTA is a quality assured platform for collecting clinicopathologically annotated biological material, imaging data, operative images, environmental assessment, questionnaires as well as patient-reported outcomes from cancer patients to support biospecimen-based translational research and clinical cancer research, including biomarker discovery to improve the understanding of tumor biology and cancer patients care.
This is a Long-term Access Programme (LAP) which aims to support provision of mepolizumab, until it is commercially available, to eligible subjects with severe asthma who participated in a GSK-sponsored mepolizumab clinical study 200862 and 200363. Eligible subjects will initiate mepolizumab within a 6-month period following the individual subject's last scheduled visit in their preceding clinical study. For each subject benefit versus risk will be assessed throughout the study to support continued treatment with mepolizumab.
The great diversity of regimens and treatment lines, the different efficacy of these, mostly due to the increase in bacterial antibiotic resistance and regional differences, requires a continuous critical analysis of clinical practice, evaluating systematically the efficacy and safety of the different regimens and the cost-effectiveness of the different diagnostic-therapeutic strategies. This will help in the design of an efficient and optimized treatment that will reduce number of re-treatments, diagnostic tests and the appearance of associated pathologies such as peptic ulcers, gastrointestinal bleeding and, probably, gastric cancers. Therefore, the evaluation of real clinical practice using non-interventionist registries will help to improve the design and organization of European Consensus on the management of H. pylori infection, which is the best way to establish healthcare efficiency. Primary aim To obtain a database registering systematically over a year a large and representative sample of routine clinical practice of European gastroenterologists in order to produce descriptive studies of the management of H. pylori infection. Secondary aims 1. To evaluate H. pylori infection consensus and clinical guidelines implementation in different countries. 2. To perform studies focused on epidemiology, efficacy and safety of the commonly used treatments to eradicate H. pylori. 3. To evaluate accessibility to healthcare technologies and drugs used in the management of H. pylori infection. 4. To allow the development of partial and specific analysis by the participating researchers after approval by the Registry's Scientific Committee Methodology Non-interventionist prospective multicentre international registry promoted by the European Helicobacter Study Group. A renowned gastroenterologist from each country was selected as Local Coordinator (30 countries). They will in turn select up to ten gastroenterologists per country that will register the routine clinical practice consultations they receive over 10 years in an electronic Case Report Form (e-CRF). Variables retrieved will include clinical, diagnostic, treatment, eradication confirmation and outcome data. The database will allow researchers to perform specific subanalysis after approval by the Scientific Committee of the study.
BACKGROUND: In industrialized countries a considerable and increasing proportion of strokes occur at younger ages. Stroke at young age causes marked disability at worst and thus long-standing socioeconomic consequences and exposes survivors for 4-fold risk of premature death compared with background population. Up to 50% of young patients with ischemic stroke remain without definitive etiology for their disease despite extensive modern diagnostic work-up (i.e. cryptogenic stroke). The group of cryptogenic strokes includes those with patent foramen ovale (PFO) or other abnormalities in the atrial septum in the heart as the only or concomitant finding. Population prevalence of PFO is high, 25%, and the mechanisms how PFO would be associated causally with ischemic stroke remain to be clarified. Moreover, there are only scarce data on clinical outcome, long-term risk of new vascular events, and prevention of such events in these patients. DESIGN: Searching for Explanations for Cryptogenic Stroke in the Young: Revealing the Etiology, Triggers, and Outcome (SECRETO) is an international prospective multicenter case-control study of young adults (age 18-49) presenting with an imaging-positive first-ever ischemic stroke of undetermined etiology (aim N=2000). Patients are included after standardized diagnostic procedures (brain MRI, imaging of intracranial and extracranial vessels, cardiac imaging, and screening for coagulopathies) and age- and sex-matched to healthy controls in a 1:1 fashion. Up to 45 study sites worldwide will be needed to recruit the planned participant population during a 3-year period. Neurovascular imaging and echocardiography studies, and ECGs will be read centrally. AIMS: SECRETO involves five principal fields of investigation: (1) Stroke triggers and clinical risk factors; (2) Long-term prognosis (new vascular events, functional and psychosocial outcomes); (3) Abnormalities of thrombosis and hemostasis; (4) Biomarkers of e.g. inflammation, atherogenesis, endothelial function, thrombosis, platelet activation, and hemodynamic stress to characterize postulated cryptogenic stroke mechanisms; and (5) genetic study, including genome-wide association and candidate gene studies as well as next-generation sequencing approach. All analyses consider cardiac functional and interatrial structural properties as a possible mediator. Furthermore, SECRETO Family Study (substudy) aims at collecting extensive family history of thrombotic events from informative patients being screened for SECRETO main study and collect genetic samples from all consenting family members for whole-genome sequencing. SIGNIFICANCE: SECRETO will provide novel information on clinical and subclinical risk factors, both transient and chronic, predisposing to cryptogenic ischemic stroke in young adults. This study also reveals long-term prognosis of this understudied patient population and may discover new genetic background underlying the disease mechanism and provide potential targets for drug development.
