Filter by:This study is designed to analyze the effect exosomes derived from red blood cell units have on blood coagulation and platelet function. It is an in vitro study using healthy volunteers' blood.
Type of study:Prospective, single-center, non-therapeutic, of routine care No randomization, no modifications of the usual care, study results are not available for the physicians in charge of the patient. Objectives: - The main objective of this study is to evaluate the ability of the thromboelastogram (ROTEM®) to detect clotting disorders related to pancreas-kidney transplantation, comparing ROTEM ® profiles during the perioperative period of two different types of transplantation (kidney alone and simultaneous pancreas-kidney) - The secondary objectives are: 1. To assess the incidence and type of coagulation disorders during the perioperative period of these two types of transplantation 2. To study correlation values between thrombolelastogram and standard coagulation parameters Population study: - Evaluated group: 40 pancreas-kidney recipients - Control group: 80 kidney recipients - Recruitment periods: 24 months - Patient Monitoring: 48 hours - Total duration of the study: 36 months. - Ethics: Study of routine care. Oral and written information given to patients. Validation of the study protocol by the local ethics committee (CPP Sud Est II: Protocol No. HCL / P 2012.727)
In this study, the investigators would like to compare a heparin-coated tubing system for minimized extracorporeal circulation (MECC) with the conventional tubing system for MECC, which does not contain heparin coating. The MECC system has been used since 14 years in the investigators' hospital as an extracorporeal system to support circulation and provide oxygen to the tissues during coronary artery bypass grafting. Until today, the investigators performed more than 5000 MECC procedures in their department.
Oral anticoagulants vitamin K antagonists (VKA) have been used for many years in the treatment of thromboembolic disorders, which are among the most costly diseases in terms of public health resources. According to the Agence française de sécurité sanitaire des produits de santé (AFSSAPS), it was estimated at about 900,000 the number of patients treated with VKA in 2008 (more than 1% of the French population). VKA are at the origin of many adverse effects, given their narrow therapeutic window. They are the cause of the death of approximately 5000 patients per year. The use of this therapy is a priority axis of reflection for the Haute Autorité de Santé. The interregion G4 (Nord Pas de Calais, Normandy, Picardy), with more than 9 million people, is particularly affected by this problem. University hospitals of our interregion, given their very substantial regional referral activity, are actually involved in managing VKA adverse side effects. Elderly population constitutes the majority of prescriptions. The main objective of this study is to compare INR of people older than 75 years measured by traditional method with those measured by capillary method with INRatio2 supply. The secondary objective is to show that this measure is not affected by the presence or absence of anti-phospholipid antibodies, probably very prevalent in the elderly, as well as to test the variability of INR measurement between different hospital.
About 25% medicines prescribed for long term conditions are not taken as directed, and approximately 15% people receiving a new medicine take few, if any, doses. The New Medicine Service (NMS) is a community pharmacy service that started in England in October 2011 which involves the pharmacist providing additional support to patients starting a new medicine for some breathing problems (asthma & COPD), high blood pressure, adult onset diabetes or medicines which reduce blood clotting. It aims to improve the way patients take their medicines improving outcomes and reducing costs to the National Health Service (NHS). The investigators will assess the effectiveness and cost effectiveness of the NMS using a research study where some people will receive the NMS, and some won't, so The investigators can look at the effect of the NMS on problems with their medicines, medicines taking and use of the NHS in general. Data will be collected in the East Midlands, South Yorkshire and London areas. The investigators will recruit 500 patients from a range of different pharmacies and follow them up at six, ten and twenty six weeks after starting their new medicine to assess effects on medicines taking behaviour, patients' reported problems with medicines, referrals to their General Practitioner (GP) and use of NHS resources. The investigators will compare the data gathered from this study with that being collected routinely by all pharmacies in England to provide wider estimates of cost effectiveness. The investigators will also explore how the NMS service is being implemented by pharmacies. A sample of patients from the main study will be followed in more detail. This will involve recording the consultations with the pharmacist and also interviewing patients about their experience of the service. The investigators will interview the patients GP to investigate their views of the service. The investigators will also try to understand why people decline the invitation for the NMS
This study will assess the effect of reversal of neuromuscular blockade with sugammadex compared with reversal according to usual care (neostigmine or spontaneous reversal) on the incidence of post-surgical bleeding events and on coagulation parameters in participants undergoing hip fracture surgery or joint (hip/knee) replacement surgery with neuromuscular blockage induced by rocuronium or vecuronium.
The aim of the study is to test if patients under oral anticoagulation therapy who are going to participate in the education program will have better Health-related quality of life, higher rate in pharmacological treatment adherence and better self efficacy to manage the treatment.
Volume kinetics is a method mostly used, so far, to study the distribution and elimination of crystalloid solutions. Voluven (in Sweden the most commonly used colloid for replacement of bleeding during surgery) is poorly studied, though. Also, a recent study showed unexpected volume kinetics for a crystalloid solution when it was given after a colloid solution. The investigators aim to study the volume kinetics of crystalloids and colloids and also the combination of the two in more detail. The investigators will also compare the invasive hemoglobin measurements with measurements from a new non-invasive tool (Radical 7, from Masimo Inc.) which could help to make volume kinetics more practical for everyday use. Finally the investigators will also study the concentrations of a few coagulation factors to see if they can explain the variations in coagulability that has been described in earlier studies of infusion solutions.
The purpose of this study is to assess the effect of possible exposure to THROMBIN JMI® on activated partial thromboplastin time (aPTT) at 48 hours post surgery in subjects with likelihood of prior exposure to THROMBIN JMI® within the past 4 years.
The objective of this study will be to assess the coagulation system in-vitro in a variety of bleeding and clotting disorders using the ROTEG analyzer and the thrombin generation assay.
