The Effects of Enzymes and Flavonoids on Inflammation and Coagulation After Marathon
InflammationDeath10 moreThe aim of the present study is to investigate changes in inflammatory status and incidence of infection after extreme aerobic physical stress (participation in a marathon). In addition, the impact of marathon running on the hemostasis and muscular state will be evaluated. Changes at the inflammatory, muscular, and rheological level will be related to ingestion of oral hydrolytic enzymes and bioflavonoids.
Remote Ischemic Preconditioning in Neurological Death Organ Donors
Organ TransplantationThe purpose of this study is to determine whether application of lower limb remote ischemic preconditioning (RIPC) after determination of brain death improves donor stability, organ quality, organ yield, and early post transplant clinical outcomes. Neurological death donors will be stratified into standard and extended criteria donors (SCD/ECD) and randomized in a 1:1 fashion to RIPC or No intervention. The primary outcome is the number of organs recovered per donor. Secondary outcomes include donor hemodynamic state, donor organ-specific function parameters, pulsatile perfusion parameters, number of organs transplanted per donor, recipient hospital free survival and delayed graft function of kidneys. The sample size is powered to detect a difference of 0.44 organs recovered.
POWER (Pulse Width Optimized Waveform Evaluation Trial)
Sudden Cardiac DeathThe objective of this study is to compare the ULV (Upper Limit of Vulnerability)/DFT (Defibrillation Threshold) efficacy between the 2.5, 3.5 and 4.5 ms membrane time constant based biphasic defibrillation waveforms. This comparison will result in identifying the optimal membrane time constant when programming the "tuned" defibrillation waveform.
OMEGA-Study: Effect of Omega 3-Fatty Acids on the Reduction of Sudden Cardiac Death After Myocardial...
Myocardial InfarctionCardiovascular disease (CVD) is the leading cause of death in North America and Europe. The major cause of CVD is atherosclerosis like coronary artery disease (CAD). The results of recent trials hint that the course of CAD may be positively influenced by an increased intake of omega 3-fatty acids. The OMEGA-Trial analyses this effect in subjects who suffered an acute myocardial infarction. They are divided into two groups, both receiving standard post-infarction therapy. The subjects of one group additionally receive 1 gram of omega 3-fatty acids daily for a time-period of 12 months, while the subjects in the second group receive 1 gram olive-oil as placebo. Within the period of 12 months all events are reported and used to analyse the efficacy and safety of the additional therapy with omega 3-fatty acids.
Investigation of the Genetic Diseases in Infants With Unknown Cause of Death
Sudden Infant DeathSudden infant death syndrome (SIDS) is a disease of an infant under one year of age, whose sudden death occurred unexpectedly, which the cause of death cannot be determined despite macro-autopsy, and toxicological, pathological and microbiological examinations. It is most common in babies aged 2-4 months. Although it cannot be attributed to a single cause, it is suggested that apnea/airway obstruction, abuse, developmental disorders, exposure to cigarette smoke, infections, toxic gases, metabolic diseases, and cardiac problems cause SIDS. It is known that genetic studies on SIDS are few and the literature reported so far is insufficient. On the other hand, as a result of rapid developments in genetic diagnosis methods, various genes associated with SIDS have been reported in recent studies. Most of the studies conducted include genetic studies aimed at investigating specific disease groups in SIDS. Although there are few studies on comprehensive investigation of genetic causes, potentially causative variants have been identified in 20% of cases where whole exome sequencing has been performed. In a study including perinatal deaths in which the reports of the Forensic Medicine Institute in our country were examined, 4% of the cases were reported as infant deaths of unknown cause. However, this study is only autopsy data and does not include metabolic and genetic examinations. For this reason, as far as we know, there is no information about the incidence of SIDS in our country. Based on this information, in our research, in the province of Ankara, the deaths of children under one year of age who died unexpectedly and suddenly were examined, autopsied, and toxicological examinations were performed on internal organ samples and body fluids taken during the autopsy by the Ankara Group Presidency of the Forensic Medicine Institute between 2018 and 2023. Genetic investigation of hereditary diseases that may lead to death of cases whose cause of death cannot be explained despite pathological and microbiological examinations will be carried out by the Whole Exome Sequencing (WES) method. The project will be carried out by researchers at Ankara University Faculty of Medicine and Forensic Medicine Institute Ankara Group Presidency. This research project was planned as a prospective, descriptive, open uncontrolled study. The duration of the project is foreseen as 12 months. Approval for our research was received from Ankara University
Pan-Asia United States PrEvention of Sudden Cardiac Death Catheter Ablation Trial
Ventricular Tachycardia (VT)The current standard of care for ventricular tachycardia (VT) includes the use of medicine called anti-arrhythmic drugs (AADs) and Implantable Cardioverter Defibrillator (ICD) therapy. These treatments are used to terminate the irregular heartbeats and bring the heart back to a normal rhythm. Catheter ablation is a procedure used to eliminate (damage) the heart cells causing the arrhythmia. Patients eligible for this may benefit from an ablation procedure in addition to an ICD to treat their VT condition or risk of developing VT. This study aims to show that treating VT with catheter ablation, if performed preemptively at the time of ICD implantation, will reduce subsequent recurrent VT, ICD shocks, and lead to improved survival.

A Longitudinal Cohort Study to Evaluate Cardiovascular Risk Factors and Disease in Haiti
HypertensionDiabetes13 moreInvestigators will establish a longitudinal cohort of ~3,000 adults >18 years in Port-au-Prince using multistage random sampling, and follow them longitudinally to evaluate the prevalence and incidence of cardiovascular disease risk factors and diseases. Cardiovascular risk factors include hypertension, diabetes, obesity, dyslipidemia, kidney disease, poor diet, cigarette smoking, physical inactivity, and inflammation. Cardiovascular disease include angina and myocardial infarction, heart failure, stroke, and CVD mortality. It is anticipated that hypertension prevalence will be ≥10% in 18-30 year olds, that hypertension incidence will be >10 events/1000 person years. Association of determinants and risk factors with CVD will also be examined. Whole blood, serum, plasma, stool, and urine samples will be biobanked for future studies.
