Filter by:The investigators propose to investigate Microbiota Transfer Therapy (MTT) for treating patients with Pitt-Hopkins Syndrome (PTHS) and gastrointestinal problems (constipation, bloating, abdominal pain). MTT involves a combination of 10 days of oral vancomycin (an antibiotic to kill pathogenic bacteria), followed by 1 day of bowel cleanse using magnesium citrate, followed by 4 days of high dose MTP-101P with an antacid, followed by 12 weeks of a lower maintenance dose of MTP-101P with an antacid.
The projects investigate if treatment with isocapnic hyperventilation can eliminate methanol from the body in a similar manner to dialysis. This is achieved by administering the antidote (fomepizole) and let the patient breathe on a isocapnic hyperventilation device while samples of blood, urine and maybe the breath are collected to measure the contents of methanol and its metabolites.
This study is being done to find out if a smartphone app can identify absence seizures. Children who have a history of absence seizures, as well as children without any seizure history, will be testing out the app. If participating the child will be guided through hyperventilation, an activity that asks the child to take quick, deep breaths. The app will record video of the child's face and sounds they make during hyperventilation. Hyperventilation is a safe and established technique frequently used during EEG (electroencephalogram) to encourage seizure occurrence. The App will be used during a regularly scheduled EEG.
Postural tachycardia syndrome (POTS) is the most common chronic cause of postural lightheadedness, and upright confusion afflicting many Americans, mostly young women. Many POTS patients hyperventilate by increasing their depth of breathing that produces tachycardia, alters blood flow and blood pooling in the body and importantly reduces brain blood flow causing "brain fog". In this proposal the investigators will demonstrate in young women that abnormal repeated brief impairment of blood pressure and brain flow just after standing sensitizes the body's oxygen sensor in POTS to respond as if it were in a low oxygen environment causing hyperventilation and its consequences. In this project the investigators will use various drugs that will help to understand the mechanisms that cause POTS in this unique subset of POTS patients who hyperventilate.
The goal of this clinical trial is to learn if yoga-based breathing styles could improve memory performance in adult persons without relevant prior experience in yoga, meditation or similar disciplines and without existing health problems which could hinder the implementation of the breathing exercises. The main questions it aims to answer are: - Can the memory performance get better ? - Can the subjective stress level be reduced ? Participants will complete a memory test while doing a specific nasal and oral breathing. They will complete a two-week training period after the test with daily nasal or mouth breathing training or no training at all, depending on the group, the are divided into. Researchers will compare the effect of different breathing styles on memory ability among themselves.
The Investigators aim to: 1. Study the effect of hyperventilation on the development of paradoxical vocal cord movement (PVCM) in healthy individuals and in patients with mild and severe asthma, 2. Relate PVCM to airway symptoms and measurements of intra- and extra-thoracic airway hyperresponsiveness (ET-AHR), 3. Evaluate the effects of inhaled anti-cholinergic agents on PVCM induced by hyperventilation. Hypotheses: 1. In health PVCM will not occur in response to hyperventilation, 2. In asthma PVCM will occur in response to hyperventilation, 3. Airway symptoms and ET-AHR will develop in parallel with PVCM, 4. Inhaled anticholinergic agents will prevent PVCM induced by hyperventilation.
Hyperventilation syndrome induce dyspnea and altered quality of life. the aim of this study is to assess the impact of chest physiotherapy on hyperventilation syndrome' symptoms
Following an acute COVID-19 infection, many patients suffer from long lasting physical symptoms that may greatly impair quality of life. Persisting dyspnea and other functional respiratory complaints could evoke Hyperventilation Syndrome (HVS) as a putative contributor of the long-COVID presentation in COVID-19 survivors. We aimed to assess the possible relationship between a HVS and previous acute SARS-CoV-2 infection.
All calls that end up on the out-of-hours general practitioners' service (OHGPS), which contain a demand for an urgent home visit, are passed on to the on-call general practitioner (GP). These calls are randomized into two arms: after the patient's informed consent, they are assigned either to one arm where the monitoring device, PICO, is applied together with the GP's general care or to the other arm where only the usual care is provided. All data such as suspected diagnosis, treatment or referral, influence of the parameters, ECG and/or alarms on the management and the user-friendliness are recorded. After 30 days, the diagnosis and evolution is requested from the patient's own GP or, if referred to a hospital, in the hospital in order to be able to compare the effect of the approach by the GP between both arms. The aim is to investigate if 1/ the use of the PICO monitoring device could improve GPs' decisions to refer to hospital or not in urgent cases; 2/ there is a difference between the diagnosis with and without the use of the monitoring device using the final diagnosis by the electronic health record of the own GP of the patient; 3/ the call to send a GP for an emergency contained sufficient information for the OHGPS phone operator to take an appropriate decision; 4/ the build-in alarms help the GP during his intervention; 5/ the PICO is easy to use during an emergency; 6/ the use of the device makes them feel more confident in transmitting the information to the Medical Emergency Team.
For almost a century, many hypotheses have converged on the idea of altered chemosensitivity in patients suffering from hyperventilation syndrome (HVS). Given the evolution of current technical equipment and the ability to maximise true positives in HVS ( using the revised hyperventilation provocation test), it seems reasonable to investigate central and peripheral chemosensitivities in HVS subjects.
