There are about 1125 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.
Observational study. Comparison of existing nutritional screening tools based on questionnaires with blood tests already performed on a routine basis. No intervention undertaken.
The aim of this retrospective study is to review the annual incidence, management, and outcomes of bile duct injuries (BDI) during laparoscopic cholecystectomy (LC) in a population-based cohort during 2008-2018 in Estonia.
The aim of this retrospective trial is to compare surgical and pregnancy outcomes of pregnant patients who underwent laparoscopic or open appendectomy for acute appendicitis.
The purpose of this dietary intervention is to study the effects of several dietary fibers on the gut microbiota at the personal level. Hypothesis 1: Intake of specific dietary fibers improves the blood lipid profile depending on the personal microbiota of the participants. Hypothesis 2: detailed food intake analysis and continuous monitoring of gut microbiota enables to draw causative interrelationships between food components, bacteria of gut microbiome and health characteristics.
The purpose of this study is to characterize the distribution of lipoprotein(a) (Lp(a)) levels among participants with a history of ASCVD as defined by their medical history and is 2-fold: - Evaluate the distribution of Lp(a) value in the overall participants with documented history of ASCVD - Evaluate the distribution of Lp(a) value in participants with documented history of ASCVD by demographics and regions
This is a prospective, multicentre observational study screening all adult patients admitted to a participating hospital over a 6-month study period (may be adjusted to 4-8 months according to recruitment) and including all patients with suspicion of or confirmed acute mesenteric ischaemia (AMI). Only admission data and hospital mortality outcome will be collected for patients in whom suspicion of AMI is not confirmed. For patients with confirmed AMI full data collection regarding diagnostics, management and long-term outcome is required. Investigators aim to recruit 40-50 sites with expected median of 10-20 patients with confirmed AMI per site during the study period (naturally depending on the size of the hospital). The start of the study is planned for Spring 2022. The aim of the study is to identify the incidence of AMI and its different forms in adult hospitalized patients, and to describe patient characteristics (demographic, clinical and laboratory) at baseline, applied diagnostics and management, as well as outcomes in patients with AMI. An additional aim is to compare the baseline characteristics and outcomes of patients with confirmed AMI to those of patients with suspected AMI in whom the diagnosis was not confirmed.
This study aims to evaluate whether remote ischemic preconditioning (RIPC) daily for 28 days reduces the symptoms of intermittent claudication in patients with peripheral artery disease (PAD). The study evaluates the effect of RIPC on patients' total walking distance (TWC), initial claudication distance (ICD), and time to relief of claudication (TRC). In addition, the trial investigates the effect of RIPC on different arterial functional characteristics and low molecular weight metabolites in serum and affected skeletal muscle.
Study to evaluate pharmacokinetics, efficacy, safety and immunogenicity of multiple switches between Humira® and ABP 501 (new high concentration formulation) compared with continued use of Humira® in participants with moderate to severe plaque psoriasis. This multi-center study is composed of two periods: A lead-in period of treatment with Humira® followed by a randomized two parallel arm period.
This Phase 3 study is a randomized, observer-blind immunogenicity and safety study of aQIV (an MF59-adjuvanted quadrivalent influenza vaccine) compared with a licensed quadrivalent influenza vaccine in adults 50 to 64 years of age.
This is a randomised, double-blind, multicentre clinical study to evaluate the efficacy, safety, tolerability, PK, and immunogenicity of SB17 compared to Stelara® in subjects with moderate to severe plaque psoriasis.
