Filter by: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.
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).
Laparoscopic Roux-en-Y Gastric Bypass (LRYGB) has been the most performed bariatric surgical intervention until a few years ago, due to its good results in terms of weight loss and remission of comorbidities such as hypertension, type 2 diabetes mellitus, dyslipidemia and obstructive sleep apnea syndrome. However, more than 25% of patients do not obtain the expected result. There is no uniform technique to perform a LRYGB, but traditionally it was constructed using a long alimentary limb (AL) and a short biliopancreatic limb (BPL). There is no current consensus on the ideal length of the LRYGB limbs. The distal gastric bypass at the expense of a longer biliopancreatic limb (LBPL-GB) could induce more excess of weight loss (EWL%), but with possible protein malnutrition depending on the length of the remaining common limb. The aim of this study is compare a LBPL-GB (BPL 150cm, AL 70cm) with LAL-GB (BPL 70cm, AL 150cm). PRIMARY OUTCOME: to evaluate if there are differences in weight loss. SECONDARY OUTCOME: to assess whether there are differences in both groups in remission of the most common comorbidities and in quality of life. DESIGN: multicenter, prospective, randomized study in blocks (1:1), blinded for the patient and to the surgeon up to the time of intervention, in patients with indication of RYGB for obesity (BMI>35 with associated comorbidity or BMI>40 with or without comorbidity, excluding those of BMI>50). Intervention: LRYGB type 1 (LAL-GB: 150cm ALand 70cm BPL) or type 2 (LBPL-GB: 70cm AL and 150cm BPL). The expected result is that the patients with LBPL-GB present better EWL%, and higher remission of their comorbidities than the comparison group
Obstructive sleep apnea (OSA) is a sleep disorder which is caused because of collapse of airway or inappropriate tongue position. As OSA becomes severe, the physical and psychological aspect might be influenced due to insomnia. In addition, many evidences revealed that OSA is related to cardiovascular disorder. Apnea-hypopnea index (AHI) and epworth sleepiness scale (ESS) are common parameters to evaluate the severity of OSA. Recently, body and tongue fat have certain relation with OSA, and the higher the fat, the more possible to get OSA. To find the treatments for OSA, myotherapy has been proved to improve AHI and ESS. The treat mechanism is speculated that increasing muscle tone around oral and oropharyngeal and decreasing tongue fat. High intensity interval training (HIIT) might be effective to OSA, for it could lower down the total body fat. Furthermore, HIIT is a time-efficient program which can increase exercise adherence. Last, less articles discussed about the effect of supervised verse unsupervised treatment and the effect of mix-model treatment. The purpose of the study is investigating the comparison between supervised HIIT plus myotherapy and unsupervised home exercise plus myotherapy. Method: 40 patients who meets the inclusion criteria will be recruited in this article during 2022/01 to 2022/12. Then, they will be randomly assigned into HIIT plus myotherapy group and home exercise plus myotherapy group. The treatment process will last for 8 weeks. All the outcomes such as AHI,ESS and body fat will be completed before and after 8 weeks treatment. The Wilcox signed test was adopted to analyze the treatment before and after the treatment sessions (time effect). The Mann-Whitney U was applied for the difference before and after treatment between two groups (group effect), and the baseline of two groups was also analyzed by this method. The significant level was set as p value< 0.05. Hypothesis: It is speculated that HIIT plus myotherapy might revealed better outcomes on AHI, ESS, and body fat.
The effect of CPAP on weight and fluid homeostasis will be assessed. Obstructive sleep apnea treatment-naive subjects will randomized to CPAP and control groups. Weight change, and changes in overnight urinary volume, intra and extracelullar volume, plasmatic B-type natriuretic peptide (BNP) and antidiuretic hormone (ADH) and urinary osmolality will be compared between groups.
