Filter by:Until now, a barrier to the widespread evaluation of adenosine in clinical practice has been the difficulty of obtaining rapid reliable measures. A rapid method has recently been developed which consists of measuring adenosine concentration in whole blood instead of plasma by means of Mass Spectrometry (LC-MS/MS). In this study adenosine plasma levels were assessed in a larger unselected cohort of patients affected by non-cardiac syncope and compared the results with healthy controls.
The main purpose of this study is to assess the reliability of a new cuffless patch BP monitor in detecting episodes of hypotensive (pre)syncope during tilt testing.
The main purpose of this study is to assess the reliability of a new patient's self-administered wearable watch-type BP monitor in detecting episodes of hypotensive (pre)syncope. Secondary aim regards the estimation of feasibility of this tool.
The Study To Understand Tilt Tests versus Extended Recordings (STUTTER, POST 10) will test the hypothesis that first performing a diagnostic HUT in older patients with syncope of unknown cause will provide earlier and more diagnoses than inserting an ICM.
About 20% of adults faint recurrently. These patients are often highly symptomatic, have problems with employment and driving, can be injured, and have poor quality of life. There are few therapies that have withstood the test of randomized clinical trials. the investigators will conduct a prospective, randomized, parallel, double-blind, proof-of-concept study that tests the hypothesis that serotonin 5HT3 receptor inhibition with ondansetron prevents tilt-induced vasovagal syncope (VVS) and pre-syncope in patients with clinical VVS. A total of 70 patients with quantitative clinical diagnostic criteria for VVS and at least 1 syncopal spell in the preceding year will be randomized in a double-blind acute phase 2 study to ondansetron 8 mg PO BID x 2 doses or matching placebo. The endpoint will be presyncope or syncope associated with diagnostic hemodynamic changes. These data should provide useful preliminary data as a foundation on which to conduct a subsequent randomized clinical trial.
Syncope is the most frequent cause of transient loss of consciousness. Falls are very common in older people. If the falls are unexplained and not accidental, it is likely that the patient had a syncope event and showed a lack of awareness for loss of consciousness. The management of unexplained falls is the same as that of syncope. There is a gap between the best available scientific evidence provided by the guidelines and the need to disseminate these concepts in clinical practice. The absence of a systematic comprehensive approach to fainting and falls results in higher health and social costs, unnecessary hospitalizations and diagnostic procedures, prolonged hospital stays, lower diagnostic rates, and higher rates of misdiagnosis and symptomatic recurrence. Aim of the study The aim of the study is to assess the efficacy (adherence) of a diagnostic protocol and the costs of a comprehensive guideline-based approach to the management of fainting and falls in a population of consecutive patients referred to a dedicated multidisciplinary outpatient facility. Primary endpoint: 1. Prevalence rate of patients with unexplained fall undergoing diagnostic investigations for syncope among those initially subjected to a diagnostic evaluation for falls. Secondary endpoints: 1. Comparison between patients initially assigned to syncope and those assigned to unexplained fall in terms of diagnostic tests and final diagnosis. 2. Comparison between patients initially assigned to syncope and those assigned to unexplained fall in terms of adherence to guideline recommendations. 3. Analysis of costs per patient of fall and syncope protocols 4. All previous analyses will be performed according to the following age groups: ≥75, 74-65 and 64-40 years. Inclusion criteria 1. Consecutive patients >40 years of age, belonging to the Cwithin Fainting and Falls for the evaluation of an episode of syncope or fall. 2. Fragile patients at risk of falling. Exclusion criteria: 1. Patients aged <40 years 2. Patients with dental falls 3. Patients with a known diagnosis of syncope 4. Patients in whom syncope and fall are secondary symptoms of severe underlying comorbidities
Multicenter Italian interventional "proof of efficacy" clinical trial that aims to evaluate the incidence of asystolic pauses and heart rate in patients with CNS who performed severe CNA identified through asystolic pauses identification by implantable loop recorder. The study is independent, "investigator-initiated," sponsored by a nonprofit scientific association called the Italian Multidisciplinary Group for the Study of Syncope (GIMSI).
SynABPM 2 proof-of-efficacy is a retrospective, multicentre, observational study performed in patients affected by hypotensive reflex syncope who had performed two ABPMs, one before and another after any therapeutical intervention aimed to increase arterial blood pressure
Identifying the mechanism of non-cardiac syncope is the essential prerequisite for an effective personalized therapy. Aim of this multicentre, prospective, cross-sectional, observational study is to assess effectiveness and diagnostic yield of a two-step standardized assessment which consists of 24-hour ambulatory blood pressure monitoring (ABPM) and of tilt-table Short Cardiovascular Autonomic Function Battery (SCAFB) which consists in carotid sinus massage (CSM), limited to patients ≥40-year-old, standing test, and head-up tilt test (HUT) performed one after the other in an uninterrupted sequence as a single procedure on a tilt table
The purpose of the study is to determine physical and mental health issues of U.K. embryologists related to their occupational characteristics, and how workplace fatigue and burnout may affect their quality of life, cynicism, interactions with patients, attention to detail, and lead to human error, the cause of the most severe IVF incidents that often make headlines and result in costly litigation. It will also correlate how the current manual workflows contribute to these health issues, and what measures can be taken to improve both working conditions and embryologists' health, and, therefore, improve patient care.
