NCT ID: NCT04881513 Recruiting - Taste Disorders Clinical Trials

The Change of the Structure and Function of Taste Buds After the Otosclerosis Surgery

Start date: January 1, 2020
Phase: N/A
Study type: Interventional

Patients admitted for the otosclerosis operation are included in the study. The Narrow Band Imaging (NBI) of their taste buds is performed before the operation. The sensory function of the anterior 2/3 of the tongue is tested with the two point discrimination discs, the taste is tested with taste strips and the SF-36 questionnaire is applied. During the operation in local anesthesia the threshold for the tongue sensation (by the stimulation of the chorda tympani nerve) of the first 2/3 of the tongue at the beginning of the operation (when we first encounter the chorda tympani nerve) and at the end of the operation is measured.One month and six months after the operation the tests are being repeated (NBI, two-point discrimination and SF-36 questionnaire). The study has the National Ethical Committee approval.

NCT ID: NCT04834869 Recruiting - COVID19 Vaccine Clinical Trials

COVID-19 Vaccines Safety Tracking (CoVaST)

Start date: April 1, 2021
Phase:
Study type: Observational

This project aims to monitor the side effects of COVID-19 vaccines worldwide actively. The primary objectives of the project include a) to estimate the prevalence of each local and systemic side effect of each COVID-19 vaccine among healthcare workers (HCW), old adults over +65 (OA), and schoolteachers (ST); b) to evaluate the potential demographic and medical risk factors for side effects frequency and intensity; c) to evaluate the long-term consequences of COVID-19 vaccines. The secondary objectives include a) to evaluate the relative safety of COVID-19 vaccines compared to each other; b) to evaluate the impact of palliative drugs used by the recently vaccinated individuals on their short-term side effects resolution.

NCT ID: NCT04825119 Recruiting - Tremor Clinical Trials

Hyperkinetic Movements in Patients With Disease of Motor Neurons and Their Response to Treatment With Nusinersen

Start date: October 1, 2017
Phase:
Study type: Observational

Hyperkinetic movement disorders in patients with diseases of motor neurons will be studied. Patients with spinal muscular atrophy (SMA) and motor neuron disease patients will be studied. Involuntary movements will be video recorded and accelerometry with electromyography (EMG) will be recorded in a subset of patients. Hyperkinetic involuntary movements studied will be tremor and minipolymyoclonus. Tremor is defined as involuntary, rhythmic, oscillatory movements of a body part, and minipolymyoclonus are intermittent and irregular movements, with amplitudes sufficient to produce visible movements of the joints. Hyperkinetic movement disorders may be of central or peripheral origin and using accelerometry with EMG may help distinguish the two mechanisms. In patients with SMA the investigators will explore the effect of Nusinersen treatment on phenomenology and amplitude of tremor and minipolymyoclonus. Aims: To explore the prevalence and phenomenology of hyperkinetic movement disorders in patients with MND and SMA and to study the underlying pathological mechanisms with the use of accelerometry and EMG. To explore the effect of Nusinersen treatment on phenomenology and amplitude of involuntary movements. Hypotheses: Based on clinical observations the investigators believe it will proven that hyperkinetic movement disorders are common in patients with disease of motor neurons. The investigators hypothesize that hyperkinetic movement disorders in MND and SMA patients are of peripheral origin, being caused by uneven graduation of contraction in the wasted muscles with large motor units being active with no sufficient previous recruitment of small units to smooth contraction of large motor units. If tremor and minipolymyoclonus in SMA are due to the activation of enlarged motor units which are caused by reinnervation of muscle fibers, the treatment with Nusinersen will increase the amplitude of tremor and minipolymyoclonus. Methods: Presence, quality, and regularity of hyperkinetic movement disorders will be defined using clinical examination, accelerometry and EMG. Hyperkinetic movements will be classified as minipolymyoclonus or tremor. In patients with SMA, the measurements will be repeated 6-12 months after initiation of treatment with Nusinersen.

NCT ID: NCT04761562 Recruiting - Clinical trials for Tympanic Membrane Perforation

Use of Autologous Plasma Rich in Platelets and Extracellular Vesicles in the Surgical Treatment of Chronic Middle Ear Infections

Start date: February 14, 2021
Phase: Phase 2/Phase 3
Study type: Interventional

This clinical study evaluates the efficacy of the autologous blood-derived product called platelet- and extracellular vesicle-rich plasma as a supplement to the surgical treatment of chronic tympanic membrane perforations. Half of the participants will be treated with standard surgical procedure called tympanoplasty and addition of platelet- and extracellular vesicle-rich plasma. Another half will be treated with only the standard tympanoplasty.

NCT ID: NCT04739904 Recruiting - Premature Birth Clinical Trials

Hypoxia Intolerance in Preterm Individuals

PreAlti
Start date: April 30, 2021
Phase:
Study type: Observational

Reduced Hypoxic Ventilatory Response (HVR) and systemic O2 saturation subsequently leading to blunted aerobic capacity as well as decreased overall physical and cognitive performance are the main physiological challenges faced by prematurely born individuals in hypobaric hypoxia (i.e. during high altitude sojourn). While these phenomena have been described previously, the underlying mechanisms are currently unresolved. Given that the reduction in altitude-performance and its underlying mechanisms are not well understood, it is currently impossible to give evidence-based recommendation for altitude sojourns in this cohort. It is also of note, that even hypobaric hypoxia exposure during long-haul flights might be detrimental to well-being of pre-term born individuals. The present project aims to comprehensively investigate physiological responses to altitude/hypoxia during rest and exercise in prematurely born, but otherwise healthy adults. Specifically, we aim to elucidate the underlying mechanisms of the altered resting and exercise cardiovascular, respiratory, cerebral and hematological responses to hypoxia in prematurely born individuals. The obtained results from this cohort will be compared to the data from a control groups consisting of healthy, age and aerobic capacity-matched individuals born at full-term. While acute hypoxic effects will be the focus of the project's first phase, we will test the effect of prolonged terrestrial (real) or simulated (normobaric hypoxia) altitude exposures in the second part. This phase will, in addition to the insight into the prolonged altitude acclimatization modulation in prematurely born individuals, also enable us to investigate the potential differences between the effects of normobaric (simulated) and hypobaric (terrestrial) hypoxia in this cohort.
