Filter by:This proof-of-concept study will evaluate the impact of surgically placing and stimulating the hypoglossal nerve and/or a second neural target Ansa Cervicalis, with a set of off-the-shelf electrode arrays.
This proof-of-concept study is being performed to evaluate whether the hypoglossal nerve can be stimulated using a small series of electrodes placed surgically via a percutaneous approach. Minimally invasive off the shelf medical devices will be used and observation of the characteristic physiological responses to stimulation of the HGN, will be assessed.
The study consist of children, who have used home ventilatory support during years 2010-2020 in Tampere University Hospital. The study will describe retrospectively different diagnoses and symptoms which will lead to home ventilatory support. We also study compliance to treatment and it's disanvantages. The prospective part of the study describes the quality of live of these children by using questionnaires (PedSQL).
Sleep is an important factor that influences long-term quality of life with known health consequences. Obstructive sleep apnea, the most prevalent disease that disturbs sleep, is considered a public health problem. Treatment with continuous positive airway pressure is cost effective and reverses the clinical consequences but there is a percentage of patients who do not tolerate it or leave it without treatment and with potential future health complications. Mandibular advancement device can be a valid and well tolerated alternative, it is known that it reduces apnea-hypopnea index, but its effect on the improvement of sleep quality is evaluated by polysomnography that interferes with the quality of sleep. There is an ambulatory monitoring device for sleep quality and circadian rhythms, which can register prolonged periods of time, under natural conditions and at a lower cost than a polysomnography. This pilot project assesses whether mandibular advancement device is an effective and well tolerated alternative in the treatment of obstructive sleep apnea to improve the quality of life and sleep in the medium and long term.
Obstructive Sleep Apnea (OSA) remains underdiagnosed in 2022, as a result of the unawareness of its serious health-related consequences and the lack of diagnosis accessibility. Respiratory polygraphy (PV) is widely used as a screening tool and sometimes a diagnosis test, although polysomnography (PSG) remains the gold standard investigation as it provides complete information about sleep architecture and arousals. Thus, it has been shown that the Apnea Hypopnea Index (AHI) and Respiratory Disorder Index (RDI) are underestimated by PV vs PSG. Approaches to substitute PSG by simpler but equally efficient diagnosis tests have included devices aiming to record complementary signals and to analyze them with Artificial Intelligence. In this context, ASEEGA algorithm has demonstrated its performance for automatic sleep scoring in healthy individuals and patients with various sleep disorders, based on a single channel EEG analysis. This study aims at comparing the real-life performance and feasibility of added single channel EEG automatic sleep scoring using ASEEGA to PV versus standard PV and PSG in adults referred to a regional sleep reference center for suspected OSA. We hypothesize that this approach (1) is as accurate as PSG and more accurate that PV for AHI analysis, and (2) is less time-consuming than PSG.
Sleep apnea-hypopnea syndrome (SAHS) is a disorder of nocturnal ventilation due to the occurrence abnormally frequent pauses in breathing. It is a public health problem that currently affects 13 % of men and 6% of women between 30 and 70 years old. Sleep apneas are conventionally divided into obstructive and central apneas, depending on the persistence or no respiratory movements and the existence or not pharyngeal collapse during apnea. There are upper airway characterization studies (VAS) in patients with syndrome sleep apnea/hypopnea (OSAS). These physiological characterization studies (measurement of critical closing pressure (Pcrit) of the VAS) and anatomical (transcutaneous ultrasound of the muscles of the floor of the mouth, the base of the tongue, or by a acoustic pharyngometry of the VAS) are interested separately to different parameters without searching correlation with the severity of sleep apnea nor their potential as a screening tool for OSAS in patients at risk. The investigators hypothesize that a strong correlation and constant exists between the physiological collapsibility of VAS, the anatomical measurements of the VAS and the degree of severity of OSAS. Thus, the aim of this descriptive study is to characterization as complete as possible of the VAS of apneic patients in a homogeneous population and a better understanding of the pathophysiological obstructive events in patients without factor obvious risk.
The aim of the study is to determine whether there is a statistically significant difference in snoring intensity before and after performing a Barbed Reposition Pharyngoplasty as a single-level snoring procedure. The investigators aim to determine whether this is a valid alternative to the more classical techniques of pharyngoplasty. Furthermore, the investigators also wish to map the various postoperative complications and compare them with those of the more conventional techniques. The investigators compare the snoring intensity before surgery with the snoring intensity at 2 weeks (first postoperative control), at 6 weeks (second postoperative control) and at 6 months (Third postoperative control). For the evaluation of snoring, the investigators use 4 scales/questionnaires. These questionnaires are currently also used as standard at the outpatient clinic for snoring problems. These 4 scales/questionnaires are completed at every check-up. During the first postoperative check-up, the postoperative side effects are checked (bleeding, infection, readmission, needed consultation with another doctor, date of resumption of work). The investigators also map the pain with a visual analog scale and measure this the day after the operation and let the patient fill it in 3 days, 1 week and 2 weeks after the operation.
This is a prospective, multicenter, non-randomized single-arm safety and efficacy study to: - Collect data to evaluate the safety of CHILLS cryotherapy to treat OSA in patients with moderate to severe disease. - Evaluate the chronic performance of the CHILLS system and collect clinical measures for therapy effectiveness that will be used to demonstrate safety and effectiveness in the next clinical study.
MIST+ is studying a nasal spray to see if it will reduce the need for surgery for snoring. Children aged 3-12 are invited to take part. Snoring affects up to 10% of children and can cause sleeping problems and concentration or behavioural issues in the daytime. Currently the most common treatment for snoring is surgery to remove the tonsils and/or adenoids, however many children wait a long time to see a specialist. This research is trying to find if nasal sprays can help children with snoring, and whether this can reduce the need for surgery.
The purpose of the study is to examine the feasibility, acceptability, and initial outcomes of clinical decision support (CDS) and a Sleep Navigation program to enhance primary to specialty care management of pediatric sleep-disordered breathing (SDB).
