NCT ID: NCT03532984 Not yet recruiting - Stroke Clinical Trials

Beam Walking Across the Lifespan for Falls Prediction

Start date: June 1, 2018
Study type: Observational

Background: Dynamic balance keeps the vertical projection of the center of mass within the base of support while the center of mass moves. The age-related decrease in dynamic balance is a risk factor for falls. Dynamic balance tests are used to predict the risks for falls and eventual falls but the psychometric properties of most tests assessing dynamic balance are unsatisfactory and comprise no actual loss of balance while walking. Objectives: Using beam walking distance as a measure of dynamic balance, we will determine the psychometric properties, lifespan and patient reference values, the relationship with selected 'dynamic balance tests', and the accuracy of beam walking distance to predict falls. Methods: This cross-sectional observational study will examine healthy adults in 7 decades (n=432) at 4 centers. Center 5 will examine patients (n=100) diagnosed with Parkinson's disease, multiple sclerosis, stroke, and balance disorders. At Test 1, all participants will be measured for demographics, medical history, grip and leg strength, short physical performance battery, static balance on a force platform, and dynamic balance using beam walking (4m-long, 4, 8, and 12 cm wide) under single (beam walking only) and dual task conditions (beam walking while concurrently performing an arithmetic task). In addition, cognitive function (global cognition, attention, executive function, processing speed, memory) will be assessed. Patients and healthy participants age 50+ will be additionally measured for fear of falling, history of falls, miniBESTest, functional reach on a force platform, timed up and go, and reactive balance. At Test 2, 7-10 days after Test 1, healthy adults young and age 50+ (n=40) will be re-tested for reliability of beam walking performance. All participants age 50+ will be re-called to report fear of falling and fall history 6 and 12 months after Test 1. Conclusion: The investigators expect to find that beam walking performance vis-à-vis the traditionally used balance outcomes predicts more accurately fall risks and falls.

NCT ID: NCT03531333 Recruiting - Glioma Clinical Trials

Intraoperative Ultrasound Guided Glioma Surgery; a Randomised, Controlled Trial.

Start date: November 1, 2016
Phase: N/A
Study type: Interventional

The main goal of high grade glioma (HGG) surgery is to achieve gross total resection (GTR) without causing new neurological deficits1-8. Intraoperative navigated high resolution ultrasound (US) is a promising new tool to acquire real-time intraoperative images to localize and to resect gliomas9-12. The aim of this study was to investigate whether intraoperative guided surgery leads to a higher rate of GTR, when compared with standard non-ultrasound guided surgery.

Start date: May 31, 2018
Phase: Phase 3
Study type: Interventional

This is a randomized, open-label, multi-center, global, phase III study to determine the efficacy and safety of Durvalumab + BCG combination therapy in the treatment of patients with non-muscle-invasive bladder cancer.

NCT ID: NCT03528551 Enrolling by invitation - Clinical trials for Congenital Bleeding Disorder

A Research Study Looking at How a Factor VIII Medicine Called Turoctocog Alfa Pegol (N8-GP) Works in People With Haemophilia A

Start date: April 30, 2018
Phase: Phase 3
Study type: Interventional

This study will look at how a known study medicine N8-GP works in previously N8-GP treated people with haemophilia A. The aim is to look at how N8-GP works during regular use. Participants will get N8-GP. N8-GP has been tested in more than 200 people with haemophilia A for several years. Participants will get an injection of N8-GP into a blood vessel, one, two or three times weekly. Participants will get more doses if they bleed or if they will need a surgery. The study will last for about 2 years. Participants will have at least 9 visits with the study doctor. If participants agree to be in this study, they will get their first injection (in this study) at the first visit. Participants will also get an injection at visit 3, 5 and 7. Participants will be trained to give all other injections themselves. Participants must not use any clotting factors other than N8-GP or any anticoagulants (blood thinners) during the study.

NCT ID: NCT03527797 Recruiting - Critical Illness Clinical Trials

Diaphragm Protective Ventilation in the Intensive Care Unit

Start date: May 16, 2018
Phase: N/A
Study type: Interventional

Due to an accident, pneumonia or surgery, patients can have severe shortness of breath or lung damage to such an extent that it compromises vital functions. At such times, mechanical ventilation can be lifesaving. The ventilator temporarily takes over the function of the respiratory muscles to ensure adequate uptake of oxygen and removal of carbon dioxide. Mechanical ventilation can usually be stopped quickly after the initial disease has been treated. Unfortunately, in up to 25-40% of ventilated patients it takes several days to weeks before mechanical ventilation can be discontinued, even after treatment of the initial disease. This phenomenon is termed weaning failure. Weakness of the respiratory muscles, such as the diaphragm, is one of the leading causes of weaning failure. Like other skeletal muscles, the diaphragm can become weakened if it is used too little. This happens often during mechanical ventilation because of excessive assistance provided by the ventilator or use of sedative medication. Excessive activity of the diaphragm can also lead to damage and weakness, just like in other muscles that have to perform excessive amounts for a prolonged period of time. Additionally, excessive work by the diaphragm might have a direct damaging effect on the lungs, which leads to a vicious cycle. As such, it is very important to find a balance between resting the diaphragm (which may lead to weakness) and placing excessive work on the diaphragm (which can damage the diaphragm and possibly the lungs). In this study, the investigators want to test whether insufficient activity and excessive activity of the diaphragm during mechanical ventilation can be prevented or reduced. The investigators plan to measure the diaphragm activity in 40 participants on mechanical ventilation. Participants will be randomly assigned to the intervention group or the control group. In the intervention group, ventilator support levels will be adjusted according to the observed diaphragm activity, in an attempt to ensure adequate diaphragm activity. The control group receives usual care. The hypothesis is that adjusting the level of support provided by the ventilator is a feasible method to improve the time that the diaphragm operates within acceptable levels of activity over a 24 hour period.

NCT ID: NCT03525236 Completed - Cancer Clinical Trials

The Oncoflavour Study

Start date: June 19, 2017
Phase: N/A
Study type: Interventional

Oral nutritional supplements (ONS) are often prescribed for malnourished patients to help improve nutritional status. Commonly in cancer patients taste and smell alterations and side effects of treatment can affect the palatability and compliance to ONS. A variety of flavours and styles are available of ONS however research of the palatability of these in cancer patients is limited. This study aims to evaluate specific flavours created based on the taste changes occuring during treatment. We aim to evaluate the patient liking and evaluation of 5 flavors in 3 different types of flavour-sensations: - Warming/spicy sensation: to trigger the senses and bring new sensations - Cooling/fresh sensation: to have a fresh mouthfeel and lighter base perception - Neutral: to avoid that patients experience additional flavour and let them the opportunity to mix it with other food
