The patients will be randomised (MitraClip® or Surgery). The Study Follow-Up includes 4 visits after procedure (hospital discharge, 1, 6, 12 months post-procedure).
This study analyzes the analgesic efficacy and adverse events of nitrous oxide 70% combined with basic analgetics compared to nitrous oxide 70% with fentanyl intranasal for analgosedation for short and painful procedures in children.
Major adverse cardiovascular events (MACE) are a leading cause of serious complications and death following major noncardiac surgery. The heart biomarkers brain-type natriuretic peptide (BNP) and high-sensitivity troponin I/T (hs-TnI/T), may aid in estimating the risk of surgery - low values may permit identifying patients at a very low risk of postoperative complications, potentially helping to avoid unnecessary tests and delays prior to surgery. Recent studies suggest that the manner in which an anesthetic is conducted may have an important impact on postoperative outcomes. The combination of low blood pressure (BP) and a deep level of anesthesia despite a low dose of anesthetic - also known as a "triple low" - has been linked to increased complications and death following surgery. However, it is unclear whether triple lows actually cause postoperative complications or whether they are merely an indicator of a sick patient, who is in general more likely to suffer from cardiovascular events in the near future. To answer this question, in this study patients will be randomly assigned to groups with lower and higher blood pressures, and the postoperative rates of major adverse cardiovascular events and of relevant increases in hs-TnI (a marker of cardiac injury) compared. Another important question is that of the optimal blood pressure target during surgery. Currently there are no established methods of tailoring blood pressure management to the individual patient. In the study the investigators will perform ambulatory 24h BP measurements prior to surgery to measure the patients' average BP during sleep. In the analysis of the study data, the investigators will try to determine the relationship of preoperative biomarker levels, intraoperative BP (both in relation to fixed targets and to the patient's own night-time BP) and of anesthetic depth with the occurrence of major adverse cardiovascular events after surgery.
In this study the investigators plan to systematically characterise infra-slow EEG oscillations during sleep, explore their relationship to the microstructure of sleep, and investigate its role in the physiology and pathophysiology of sleep by co-registration of Full band EEG with polysomnography during wake and sleep in healthy subjects, after sleep deprivation, and in patients with restless legs syndrome/periodic leg movements during sleep (RLS/PLMS).
Using European data from patients included in the Named Patient Program (NPP) and from the early post-marketing authorization period, the present study aims to describe patient characteristics and to describe the effectiveness of Daclatasvir (DCV)-based regimens in Europe. This will be a retrospective cohort study of patients who received treatment with a DCV-based regimen in the following context: - Patients enrolled within the European NPP in one of the following countries Austria, Denmark, Italy, Sweden, Spain, Switzerland, United Kingdom; or - In those countries where DCV is commercially available (ie, Sweden, Germany, United Kingdom), patients who received DCV during the early post-marketing authorization period The results of this study will contribute to a better understanding of effectiveness of DCV-based regimens in a population that differs from population in the clinical trials, and therefore will provide additional valuable information to inform clinical practice. This study intends to estimate primarily the effectiveness of DCV-based regimens as measured by the sustained virologic response at post treatment follow-up visit week 12 (SVR12). As well as estimate the effectiveness of DCV-based regimens as measured by SVR12 after the end of Hepatitis C virus (HCV). This study intends also to describe as secondary objectives the characteristics (ie, demographic and clinical characteristics and treatment patterns of patients starting a new DCV-based regimens) of patients receiving DCV as well as the effectiveness of DCV-based regimens as measured by: - On-treatment virological response at post treatment follow-up visit Week 4; and - Virological response at the end of treatment (EOT); and - The sustained viral response at post treatment follow-up visit Week 4 (SVR4) and post treatment follow-up visit Week 24 (SVR24); and - The occurrence of virological failure (on-treatment and relapse). An exploratory objective will be to assess the concordance between SVR4 and SVR12 among the overall population treated with DCV.
Prospective, randomized, open-label, single-center, investigator-initiated trial, including patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PPCI) within 12 hours of the symptom's onset. The study aims to compare platelet inhibition (pharmacodynamics and pharmacokinetics) of pre-hospital Ticagrelor in patients with STEMI according to two different analgesia protocols using Fentanyl or Morphine.
It is critical to improve our understanding of knee osteoarthritis and to design better therapeutic options for this disease. The function of the knee during walking is an important factor in the development and progression of the disease. Many models of insoles that can be inserted in regular shoes with the objectives of improving the function of the knee are available on the market without prescription. Prior studies on these insoles failed to report clear benefits for the patients, mainly because the results varied strongly between persons. Walking is a complex tasks and it is well known that everybody develops his/her individual way of walking (ie., there are subtle but very important differences in the function of the knee). This observation and the fact that patient responses could vary between individuals suggest that using the same standard insoles with all patients might not be appropriated. This further suggests that care could be greatly improved if it was possible to identify patients that would respond positively to a model of insoles. Unfortunately, while several randomized controlled trials were conducted on these insoles for knee osteoarthritis, there is a paucity of data regarding their effects on the ambulatory function of the knee. Therefore, this study aims to improve the understanding regarding the effects of insoles freely available on the market in terms of knee mechanics during walking and its relation with quality of life. This study will test the hypotheses that (i) insoles have an effect on the static and dynamic lower-limb function and (ii) that benefits perceived by the patients are related to the mechanical effects produced by the insoles.
The purpose of the study is to evaluate whether the novel anti-cancer drug OXY111A is safe and tolerated in patients with primary and secondary hepato-pancreato-biliary and gastrointestinal neoplasia as measured by exploring the maximum tolerated dose (MTD). At level of MTD, additional patients will be included aimed for assessing the efficacy profile in these neoplasia entities.
Young postmenopausal women with osteopenia / or women with osteoporosis and a FRAX score below pharmacologic treatment indication have limited treatment options in the prevention of osteoporosis/treatment of osteopenia. Further, there is a concern about long-term side effects of bisphosphonate treatment among young postmenopausal women, and hormone replacement therapy has been controversial. In a pilot study 20 microgram Calcifediol Hy.D improved several muscle related function in this target population within 4 months of treatment, which can help to prevent falls and associated bone fractures. Thus the main aim of this study is to test whether Calcifediol Hy.D at a daily dose of 20 μg / day improves muscle function (lower extremity test battery) compared with (1) placebo and compared with (2) 3200 Vitamin D3 IU per day, at 3 and 6 month follow-up. As a secondary and exploratory objective of this study, the investigators will compare the beforementioned doses on muscle strength and the quality of the bones, beside muscle mass, body composition and systolic and diastolic blood pressure measurements.
