There are about 4372 clinical studies being (or have been) conducted in Greece. 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.
This study will investigate the incidence of postoperative POD in patients undergoing non cardiac surgery under general anesthesia with and without the implementation of the BIS monitoring.T
Preliminary evidence suggest a possible relationship between Neutrophil-Lymphocyte Ratio (NLR) and Platelet-Lymphocyte Ratio (PLR) and perioperative neurocognitive disorders (NCD). We are going to investigate whether the values of NLR and PLR in patients undergoing elective non-cardiac surgery under general anesthesia, are related with increased risk of perioperative NCD.
Preliminary evidence suggest a possible relationship between HbA1c and perioperative neurocognitive disorders (NCD). We are going to investigate whether the preoperative value of HbA1c in patients undergoing elective non-cardiac surgery under general anesthesia, are related with increased risk of perioperative NCD.
Different attitudes and perceptions are encountered concerning contemporary presbyopia management. Exploration of ophthalmologists' attitudes on diagnostic and therapeutic management of presbyopia is essential for the development of disease management interventions by the Hellenic Ministry of Health and Welfare. Within this context, Greek ophthalmologists' perceptions on presbyopia will be explored by means of a custom questionnaire.
This protocol will report on the validation of IASP clinical criteria for indentifying nociplastic pain. The study will include 2 phases. In the first phase, the vignette method will be used while the second phase will include the use of the algorithm in the evaluation of patients with chronic pain.
Scientific knowledge about the COVID-19 pandemic and the virus that is causing it (SARS-CoV-2) is developing rapidly, and the investigators have a clearer idea of the population groups who are at higher risk of becoming infected, having serious illness, and dying. However, less is known about COVID-19 in children, adolescents and young adults living with HIV. It is not yet known whether, or how, HIV affects people's risk of being infected with the virus or becoming ill. This study aims to find out whether children and adolescents living with HIV have had the COVID-19 virus, even if they did not have symptoms and did not realise it at the time. When a person is infected with a virus, their immune system fights the infection. As a result, they produce proteins called antibodies, and it may take a few weeks for enough antibodies to be made to be detected by a blood test. These antibodies may help protect the person from getting the same infection again. This study wants to find out how many children and adolescents living with HIV across Europe and South Africa have antibodies to the COVID-19 virus. It wants to see if the proportion with antibodies is different in younger children compared to older adolescents and young adults, and whether it varies between different countries. Children and adolescents with HIV regularly attend hospital outpatient appointments, and during these appointments blood samples may be taken to monitor their health. This study will invite these patients to be tested for antibodies to the COVID-19 virus during their routine visit. The participants will be asked a few short questions about COVID-19 diagnoses in their household and other risk factors for exposure to the virus, and it will collect information on their HIV, medications and any other illnesses they may have. At their next routine clinic visit, approximately 6 months later, it will test them again for antibodies. Testing twice will let see how the percentage of children, adolescents and young adults with antibodies to the COVID-19 virus has changed over time. In South Africa, HIV-uninfected adolescents from a similar socioeconomic background to those living with HIV and recruited to the study will be invited to join this study, which will allow us to compare the prevalence of antibodies across the two groups. The information from this study will help scientists and healthcare workers care for children, adolescents and young adults living with HIV during the ongoing COVID-19 epidemic in the best possible way. Participants may be given their test results, together with information about what the result means, depending on the usual practice within their clinic.
The aim of this study is to examine and compare the effect of Levosimendan and Milrinone administered intravenously and via inhalation respectively in cardiac surgery patients with pulmonary hypertension and right ventricular dysfunction.
The aim of this randomized one-blinded study will be to evaluate the efficacy and tolerability of two different oral doses of tapentadol and compare it to tramadol (an opioid commonly used to treat post-surgical pain) in cardiac surgery patients
The purpose of this Phase 3 study is to evaluate the efficacy and safety of Luspatercept compared with placebo in subjects with myeloproliferative neoplasm (MPN)-associated Myelofibrosis (MF) and anemia on concomitant Janus kinase 2 (JAK2) inhibitor therapy and who require red blood cell count (RBC) transfusions. The study is divided into Screening Period, a Treatment Phase (consisting of a Blinded Core Treatment Period, a Day 169 Response Assessment, a Blinded Extension Treatment Period, and an Open-label Extension Treatment Period), and a Posttreatment Follow-up Period. Following the Day 169 Response Assessment, subjects who did not show clinical benefit will have the option to unblind. Subjects who were on placebo during the Blinded Core Treatment Period will have the opportunity to crossover into the Open-Label Extension Treatment Period and receive Luspatercept.
Percutaneous PFO closure has been established as a first-line therapy for preventing recurrent strokes in selected patients. The devices used for the specific purpose contain and release nickel, which is considered as the most allergen metal in nature. Skin patch tests are considered as gold-standard for documenting nickel allergy. While the allergic contact dermatitis induced by nickel is well described, literature is inadequate on explaining the effect of nickel release on the clinical manifestations of patients implanted with such devices. Our prospective, randomized, blinded trial will try to investigate the above by performing nickel skin patch tests to all patients, 14 days before and 90 days after the implantation. During follow-up, clinical manifestations and transthoracic echocardiographic findings will be evaluated and associated with patch skin tests.
