NCT04339816
Trial design: Prospective, multi-centre, randomised, pragmatic, double blind trial Methods: Participants: Adult (\>18 years) within 24 hours of admission to intensive care unit with proven or suspected COVID-19 infection, whether or not mechanically ventilated. Exclusion criteria: symptoms of febrile disease for ≥1 week, treatment limitations in place or moribund patients, allergy or intolerance of any study treatment, incl. long QT syndromes, participation in another outcome-based interventional trial within last 30 days, patients taking Hydrochloroquine for other indication than COVID-19, pregnancy. Interventions: Patients will be randomised in 1:1:1 ratio to receive Hydrochloroquine 800mg orally in two doses followed by 400mg daily in two doses and Azithromycin 500 mg orally in one dose followed by 250 mg in one dose for a total of 5 days (HC-A group) or Hydrochloroquine+ placebo (HC group) or placebo + placebo (C-group) in addition to best standard of care, which may evolve during the trial period but will not differ between groups. Objective: To test the hypothesis that early administration of combination therapy slows disease progression and improves mechanical-ventilation free survival. Outcomes: Primary outcome: Composite percentage of patients alive and not on end-of-life pathway who are free of mechanical ventilation at day 14. Secondary outcomes: Composite percentage of patients alive and not on end-of-life pathway who are free of mechanical ventilation at day 14 in the subgroup of patients without the need of mechanical ventilation at baseline. ICU-LOS D28 and D 90 mortality (in hospital) Tertiary (exploratory) outcomes: Viral load at D7 of study enrolment (No of viral RNA copies/ml of blood), proportion of patients alive and rtPCR negative from nasal swab at D14, Difference of FiO2 requirement and respiratory system compliance between day 0 and 7. Randomization: In 1:1:1 ratio and stratified according to study centre and patients age (cut-off 70 years) Blinding (masking): Patients, treating clinicians, outcome assessors and data analyst will be blinded to study treatment allocation. Unblinded study pharmacist or research nurse will prepare investigational products.
NCT02026245
In this study we will compare two electronic goniometric gloves to see if they can be used in research on joint movement in arthritis. One of the gloves we will use is the commercially available '5DT Ultra 14 glove', the other is a glove that we have specially designed and developed for use in people with arthritis. Both gloves are 'high-end' gloves with sensors for all of the finger and thumb joints. We aim to find out if the gloves are accurate and if they can be worn and used without too much discomfort by people with arthritis.
NCT04616222
Celsior® is an organ preservation solution used for the harvesting and the preservation of solid organs. Its use as a crystalloid cardioplegia solution has been established recently. Its main advantage is the long duration of myocardial protection. Compared to the other cardioplegia solutions, it allows a reduced amount of solution administered during the surgery and fewer interruptions during the intervention for the administration of supplemental doses of cardioplegia for long and complex operations. The objective of this register is to compare the safety and the efficacy of Celsior® to the old cardioplegia solution Saint-Thomas used as cardioplegia solution in surgery of the transposition of great vessels, the arterial switch operation.
NCT01857557
This trial assesses the impact of a supervised aerobic exercise program by a kinesiologist in patients with migraine. Patients can be assigned to one of two groups 1)The exercise group or 2)non-exercise group. This is a important area to study because there is currently limited information regarding exercise and its impact on migraine frequency and severity. In many cases, migraine patients are disabled by their headaches and sometimes will not have a significant response to medications. As a result, it is important to study other non-pharmacological interventions. In this study, the investigators hope to show the benefits of exercise by a reduction in number of headache days per month as well as by improvement in quality of life, disability,depression,anxiety,and aerobic fitness.This study will not interfere with the usual treatment patients receive at our headache clinic and patients can remain on medications deemed necessary.
NCT03564210
This study will prospectively examine the effect of screen time on recovery from concussion. Patients 12 to 25 years of age presenting to the ED with a concussion will be randomized to allow for screen time as tolerated or to abstain from screen time for the first 48 hours of recovery. The amount of screen time use and duration of concussive symptoms will be assessed through daily surveys and a daily post-concussive symptom score (PCSS).
NCT04618419
The primary aim of the study is to assess the reliability of predicting fluid responsiveness in adults undergoing coronary artery bypass graft surgery using sonogram of the internal jugular vein for assessment of vessel distensibility in relation to stroke volume variation (SVV) measaured by electrical cardiometry. The secondary aim is to evaluate the ability of thoracic fluid content (TFC) measured by electrical cardiometry to be an additive value for the assessment of fluid responsiveness.
NCT03758235
The aim of the original study was to compare Incobot/A versus Onabot/A in order to evaluate if the differences in the pharmacologic formulations between the two drugs could affect their efficacy and safety in the treatment of neurogenic overactive bladder (OAB). In the original study protocol two different dosages for either Incobot/A and Onabot/A (200 U and 100 U) were considered, to treat patients with neurogenic detrusor overactivity incontinence performing intermittent catheterization (IC) with higher dosages and those able to void spontaneously with lower dosage, with the resulting four treatment groups. For such a study, a very large sample of participants should have been treated and followed up, to have adequate power to demonstrate the hypothesis. At the end of last February 2020, we had to temporarily stop all the clinical activities related to the study and patients' recruitment, due to the occurrence of Sars-Cov-2 pandemic in our Country. At that point, a non-inferiority study seemed to be possible and adequate, and we adapted the protocol accordingly. In addition, on the basis of previously published information, we could hypothesize that the new drug (Incobot/A) would have had at least a roughly similar effect to the control drug (Onabot/A). In order to perform a non-inferiority study, the power and sample size analysis have been re-planned. Thus, we perform a not planned interim analysis to show the preliminary results of an ongoing, non-inferiority trial in which patients' recruitment temporarily stopped due to incontrollable external factors. The present study will be aimed to assess the non-inferiority of Incobot/A compared to Onabot/A on the efficacy and safety parameters, in the treatment of patients with refractory NDOI performing IC, who are randomized to receive 200 U of Incobot/A or Onabot/A intradetrusor injections and who are followed up to 12 wks after treatment

NCT02124486
Idiopathic intracranial hypertension (IIH) is a condition with an unknown cause or causes. The condition is associated with raised pressure in the brain and can cause disabling daily headaches and loss of sight, which can be permanent. The raised brain pressure squashes the nerves supplying the eye (also known as papilloedema) and this can affect vision. Over 90% of patients with IIH are overweight and weight loss is the most effective treatment. Other treatments for IIH have very little current evidence to support their use. Weight loss is difficult to maintain. This trial aims to compare two methods of weight loss, bariatric surgery and the most effective dietary programme commonly available, Weight Watchers, to see which offers the most effective sustainable treatment for IIH. Bariatric surgery is recommended by the NICE clinical guidelines for patients with a Body Mass Index (BMI) of over 40, or over 35 with a co-morbidity. Women suffering from IIH have a BMI on average around 38 and IIH is not recognised as a co-morbidity for bariatric surgery. This trial will recruit 64 women with IIH from Neurology and Ophthalmology clinics in UK NHS Trusts. They will be randomised and 32 participants will be allocated to the dietetic intervention arm, and be enrolled in their local Weight Watchers group. 32 participants will be allocated to the bariatric surgery arm, and will be referred to their local bariatric surgery pathway to receive bariatric surgery. Both groups of participants will be allocated to a treatment arm which is proven to bring about weight loss. Participants will then be followed up for five years, with the most important measurement being their brain pressure after one year of being in the trial. A further 20 obese women who don't suffer from IIH will be recruited to compare the baseline symptoms and biomarkers of those with IIH; they will take no further part in the study. 5 further healthy individuals will be scanned twice in an MRI test group to validate the MRI scan sequence to be used in the trial.

Around half of the participants will receive standard board books at the 6, 9, and 12 month well visits, while the other half will receive digital e-books.
NCT04317378
An increasing number of children undergo Magnetic Resonance Imaging (MRI). In MRI, radio waves and magnetism are used to form images of the body's interior, to diagnose and monitoring diseases in children. Many children are sedated to be able to collaborate with the MRI procedure. Sedation and general anesthesia cause the child to some extent to lose the ability to regulate his or her own bodytemperature. MRI rooms are most often cold due to the function of the magnet, leading to a risk of hypothermia in young children. Conversely, the MRI scanner generates radio frequencies that are absorbed by the body and converted to heat, which especially in small children due to their large surface area can potentially result in an increase in bodytemperature. In this study we therefore want to investigate changes in bodytemperature in children who are undergoing MRI- scanning within the Neuroanesthesiology Clinic. Furthermore, we want to define possible risk factors for possible temperature changes. Our hypothesis: Children undergoing MRI scanning increase in bodytemperature.
NCT03924232
Critically ill patients are characterized by wide variations in their carbohydrate, lipid, and protein metabolism. Such variations can lead to increase in their energy requirement with accelerated protein catabolism and ultimately alterations of their immune and gastrointestinal systems, and in a variable frame time, it lead to a disruption of muscular function that increased the ICU and hospital stay and mortality. There are multiple methods to conduct these measurements. However, the accuracy of these measures could be very scares. Skeletal muscle wasting in the critically ill is often masked by fluid retention. For these reasons, in the last few decades, several different tools have been developed to integrate the clinical and biochemical nutritional evaluations. Among these, the bioimpedance analysis (BIA) and the muscular ultrasonography (MU) seem to be promising tools for this purpose. The aim of this project is to compare and integrate the data collected by BIA and MU and the routinely clinical used parameters of nutrition to define the nutritional status of critically ill patients. The data from these tools and the biochemical and anthropometric nutritional data (including the nutritional support) will be collected at the admission in ICU and followed up within the first week of ICU stay.
NCT03395756
Background: The prevalence of repeat unprotected intercourse after EC use in the same cycle demonstrate the need for more self-bridging emergency contraceptive options. We propose the use of intramuscular Depot Medroxyprogesterone acetate (DMPA) as EC, which has been shown to inhibit follicular activity within 24 hours, and provide on-going contraception via suppression or disruption of ovulation. Objective: The objective of this study is to explore the potential of depot medroxyprogesterone acetate (DMPA) given as a 150-mg intramuscular injection for use as an emergency contraceptive. Study population: Healthy regularly menstruating women aged 18-39 years old will be invited to participate if they fulfill inclusion criteria. The participants will undergo a screening visit during the midluteal phase of their cycle, and will be enrolled if a serum progesterone level is \>3ng/ml. Methodology: Participants will be assigned to one of three groups based on leading follicle size. Starting cycle Day 8, transvaginal ultrasounds will be performed to assess the size of the leading follicle. Once the follicle has reached the pre-assigned size, 150 mg IM DMPA will be administered. Blood will be collected for baseline hormonal assays. For 5 consecutive days, daily blood will be drawn for hormonal assays and daily transvaginal ultrasound will be performed to assess for signs of ovulation. The participant will then return for twice weekly progesterone levels for 2 weeks for study completion.
NCT02779998
Acute respiratory failure is frequent during rhythmology procedure under light sedation in high risks selected patients. Non invasive ventilation (NIV) is recommended for acute cardiogenic pulmonary oedema and sleep apnea. The investigators will perform a monocentric, prospective, randomized controlled trial to compare the efficacy of NIV which associated pressure support ventilation (PSV: 5 to 15 cmH2O) and positive end expiratory pressure (PEEP: 5 to 10 cmH2O) with standard oxygen therapy in prevention of peroperative respiratory event. Our hypothesis is that peroperative use of NIV should reduce the incidence of apnea and hypoxia during procedure in rhythmology under light sedation.
