Filter by:People with chronic diseases such as diabetes, hypertension (high blood pressure) and cardiac (heart) arrhythmias tend to go to the doctor more often and have more tests done than those without those diseases. This can lead to increasing costs of healthcare and extra visits to doctors and healthcare facilities. There are now medical devices that can be used at home to monitor blood sugar, blood pressure, heart rhythms as well as other measurements. There have been some studies which show that when people take their own health readings, they are better able to control their disease, stay healthier and go to the doctor less often. In order to participate in the study participants will have been diagnosed with 1 or more of the following: Diabetes, Hypertension, Cardiac Arrhythmias. This study is designed to test those devices and see if they can help participants stay healthier through the recording and tracking of health measurements. Investigators will also be testing how easy it is to use these devices and whether or how easy it is to fit them in their daily schedule. Participants will be given an iPhone for use during the study and their recordings will be stored and displayed on the phone.
The Olympus ScopeGuide® is a useful tool in speeding up colonoscopy and making it less painful for patients. It is currently contraindicated by the manufacturer for use with patients with implantable electronic devices (such as cardiac pacemakers). There is no evidence to back up this contraindication and with the number of pacemakers being inserted increasing by around 30 000 annually in the UK, more patients will be denied the use of this device should they require a colonoscopy. Participants with Pacemakers or Implantable Cardioverter Defibrillators will attend their check appointment. Following this they will be asked to lie with a colonoscope connected to the ScopeGuide® placed onto their abdomen (with clothes on) for 2 minutes. During this time they will be monitored for any irregular cardiac activity which may indicate electromagnetic interference. After this a second device check will occur and the participant will be sent home. The hypothesis is that the ScopeGuide will not interfere with the cardiac devices.
The objective is to investigate the effect of a comprehensive sexual rehabilitation program, consisting of a psycho-educative component and a physical exercise component. The primary hypothesis is that, a comprehensive sexual rehabilitation program improves sexual function.
A multicentre, prospective observational study to develop, evaluate and validate Patient Reported Outcome Measures (PROMs) for patients treated with cardiac ablation for symptomatic cardiac arrhythmias
Cardiac ablation is an invasive procedure requiring anesthetic support for immobility and analgesia. Benzodiazepines and opioids are the most commonly used agents, while they are associated with respiratory depression and hypotension. The aim of this study was to compare the effect of remifentanil and dexmedetomidine, which exerts sedative and analgesic effect without serious respiratory depression, with conventional midazolam/remifentanil combination on sedative and analgesic levels in patients undergoing endocardial ablation.
The number of active electrical cardiac implants such as internal cardioverter defibrillators (ICDs), pacemakers or cardiac contractility modules (CCM) has significantly risen over the last two decades. This has been paralleled by an increase in the number of sources of electromagnetic fields in daily life and occupational circumstances. To date it remains unclear whether patients are at risk of device failure when being subjected to these fields. There are currently no general guidelines available to help clinicians informing their patients about safety levels and behavior around these electromagnetic fields. This study aims to identify the thresholds of safe use of these devices and potential failures under worst-case conditions in 50/60 Hz fields (i.e. power line frequency). Device implanted patients will be exposed to electric, magnetic and combined fields of different intensity at various device programming (e.g. nominal and maximum sensitivity). The results will show whether patients are safe in public or occupational environments, which medical relevant disturbances can occur and if a correlation exists between disturbances and device type or patients physique.
We are trying to investigate whether intraoperative dexmedetomidine infusion could decrease the incidence of intraoperative hypokalemia and arrhythmia, and myocardial injury in patients undergoing off-pump coronary artery bypass graft, and trying compare these effects with those of remifentanil infusion.
The purpose of this study is to compare short term (up to 48 hours) traditional cardiac rhythm monitoring using a standard ambulatory Holter monitor versus long term (up to 14 days), continuous ambulatory cardiac rhythm monitoring using a new device cleared by the FDA (Zio® Patch), iRhythm Technologies, Inc., San Francisco CA) in patients with suspected cardiac arrhythmias.
Understudied drugs will be administered to children per standard of care as prescribed by their treating caregiver and only biological sample collection during the time of drug administration will be involved. A total of approximately 7000 children aged <21 years who are receiving these drugs for standard of care will be enrolled and will be followed for up a maximum of 90 days. The goal of this study is to characterize the pharmacokinetics of understudied drugs for which specific dosing recommendations and safety data are lacking. The prescribing of drugs to children will not be part of this protocol. Taking advantage of procedures done as part of routine medical care (i.e. blood draws) this study will serve as a tool to better understand drug exposure in children receiving these drugs per standard of care. The data collected through this initiative will also provide valuable pharmacokinetic and dosing information of drugs in different pediatric age groups as well as special pediatric populations (i.e. obese).
This prospective observational study will investigate the frequency of new onset atrial fibrillation (AF) and of further cardiac arrhythmias as well as of (clinically silent) cerebral lesions in endurance runners before, during and after the BMW-Berlin Marathon 2011.
