This is a prospective, observational study evaluating the relationship between severity of sleep apnea with severity of cognitive fog and if treatment of sleep apnea with CPAP improves cognitive fog in a cohort of post COVID patients with sleep apnea.
Background:Metabolic syndrome is a disorder characterized by abdominal obesity,hypertension,increased triglycerides ,decreased HDL cholesterol and increased blood glucose. Accumulating evidence strongly indicates that insulin resistance and an increased amount of abdominal fat are the pathogenic factors for the characteristics of metabolic syndrome. Studies indicate that sleep apnea may be a manifestation of the metabolic syndrome. Subjects and methods:This study was conducted in the pulmonology department at kasrelainy hospital. It included 80 patients who came to the sleep lab unit for polysomnography. Each patient was subjected to full history taking including(sex,age,smoking history,presence of diabetes or hypertension),thorough clinical examination with emphasis on waist, neck&hip circumference and blood pressure measurements,Laboratory investigations including :Lipid profile& Diabetic profile(HBA1C).In addition to ESS and stop bang score questionnaire.
During sleep, many people have times when they breathe shallowly or completely stop. If a person stops breathing for more than 10 seconds, this is called an 'apnoea'. If shallow breathing lasts for more than 10 seconds, it is called a 'hypopnoea'. If a person has these events frequently, it disrupts their sleep and they do not awake refreshed. It can also put strain on the heart, leading to cardiovascular conditions. These sleep disorders, usually called 'Sleep Apnoea', can be treated for most people using 'continuous positive airways pressure', CPAP. Current tests for sleep apnoea, usually used at home, are expensive, complicated for patients to use and do not monitor actual breathing. The new test, called Apne-Scan, is very simple and will cost less than the standard tests. It just requires the user to wear a mask, similar to ones used for CPAP treatment, overnight and then send the mask off for data analysis. The Apne-Scan mask, developed with taxpayer funding, is fitted with a pressure sensor to monitor actual breathing. People between the ages of 18-70 who have been referred to the sleep clinic at Royal Stoke University Hospital are eligible to participate in this exploratory study. They will wear the Apne-Scan mask at the same time as their standard overnight sleep apnoea test. The breathing data collected by Apne-Scan will be analysed by Apnea-Tech Limited, the device manufacturers, so that it can be compared to the data captured by the standard sleep apnoea test.
Obstructive sleep apnea (OSA) is a prevalent kind of sleep-disordered breathing affecting one-seventh of the world's population. Almost 45 percent of this population suffers from mild to severe apnea. However, in many cases it remains undiagnosed, leading to increased health risks. Sleep-disordered breathing, as seen in OSA, can have serious long-term consequences, including sympathetic nervous system activation, sleep disturbances, heart remodeling, and cardiovascular disease development. Polysomnography is the standard method for assessing sleep-breathing disorders, which requires the attachment of various sensors by a trained technician or a healthcare professional. However, if the diagnosis of OSA depends on referral to a sleep laboratory, and if the referral is reliant on symptoms of an OSA syndrome, then current screening approaches may exclude a large population of individuals at risk. Besides, the number of sleep centers and caregivers is limited, and the associated costs are high. Therefore, alternative techniques allowing home monitoring are necessary. The goal of this observational study is to evaluate the accuracy of the Kinocardiography technique in detecting apneic episodes during sleep and comparing the results with the gold standard polysomnography in 47 patients suffering from obstructive sleep apnea. We hypothesize that this device is able to detect sleep-disordered breathing events, and thus to compute the apnea-hypopnea index, with an accuracy that is close to that of the polysomnography. Participants who meet the criteria will be invited to participate in this protocol and do both polysomnography and kinocardiography records simultaneously at night during sleep.
This observational study aims to learn about the correlation between the improving comorbidities associated with obesity after MGB (Mini-Gastric Bypass) surgery and changes in body composition in morbidly obese patients. The main questions it aims to answer are: To study the correlation between the improving comorbidities associated with obesity after MGB(Mini-Gastric Bypass) surgery and changes in body composition. Other objectives are: - Changes in the parameters of the metabolic syndrome after surgery - Changes in the cardiovascular risk biomarkers after metabolic surgery - Emergence in complications arising out of surgery requiring any intervention or causing a prolonged hospital stay, or requiring additional outpatient visits. Type of Study: An observational study in which participants with morbid obesity will undergo mini-gastric bypass surgery as per routine protocol. No separate experimental interventions will be done in the study for the participants.
The standard for treatment for people suffering from obstructive sleep apnea (OSA) syndrome involves the use of Continuous, or Automatic Positive Airway Pressure (CPAP, APAP) machines, which work by delivering air via tubing and mask to a patient at pressures of up to 20cmH2O. This increased pressure is meant to stabilize the airway to reduce obstruction events. APAP machines are generally more effective and more comfortable for patients than CPAP machines because these devices automatically adjust pressure to treat an apnea. As a result of the high rate of patient dissatisfaction with conventional PAP therapy, alternative treatments for sleep apnea have been developed. One therapeutic target for OSA is stimulation of the genioglossus muscle, a phasic respiratory muscle important in maintaining upper airway patency. Recently, it has been shown that genioglossus reflex responses can be achieved through the application of negative pressure pulses as well as changes in airway pressure. These studies focused on activating pressure-sensitive mechanoreceptors within the upper airway known to contribute to genioglossus activity. Together, these studies have demonstrated that both brief pulses of negative airway pressure and changes in airway pressure are capable of eliciting genioglossus reflex responses. The goal of this interventional study is to evaluate the potential of airway muscle activation on sleep-disordered breathing during sleep therapy by applying brief maneuvers of air pressure using existing pressure and flow sensors in conventional CPAP machines.
ThermPaed is a Sheffield Children's Hospital research collaborative which investigated the clinical diagnostic capabilities of high resolution thermal imaging (HRTI) in paediatrics. This research utilises thermal imaging techniques to detect fractures, arthritic inflammation and infection. ThermPaed proved HRTI has potential in paediatrics and resulted in development of techniques that has led to the current research study. The purpose of this study is to develop HRTI as a non-contact child-friendly means of measuring and monitoring paediatric airflow. Sheffield Children's Hospital Sleep Unit performs 500 sleep studies a year to investigate paediatric sleep-related breathing disorders. 1-6% of children have problems with their breathing during sleep and have breathing pauses called apnoeas. The condition needs accurate diagnosis and treatment to ensure correct blood oxygen levels. During a sleep study a number of physiological parameters are measured. These include heart rate, chest movements, airflow, oxygen levels, body position, snoring, movement and video. A total of 13 sensors are attached to the child whilst awake, and then the child settles to sleep. Airflow parameters are measured by two contact sensorsÍž one measures airflow by temperature and the other measures airflow by pressure. Both sensors are placed in or very close to the nostrils to detect and classify apnoea. Due to their contact nature, these sensors are poorly tolerated. In a recent survey of 100 sleep studies on the sleep unit, 50% children did not allow the sensors to be attached or removed them immediately causing difficulties in interpreting their condition. Breathing generates changes in temperature around nose and mouth which can be detected with HRTI. The investigators will recruit 30 children who are undergoing a sleep study. The investigators will compare airflow measurements from the existing clinical nasal sensors and HRTI to evaluate whether this new technique will provide an accurate non-contact alternative to measure respiration airflow.
Chronic Obstructive Pulmonary Disease (COPD) and Obstructive Sleep Apnea (OSA) are both frequent respiratory diseases with estimated prevalences between 8 and 15% of the adult population. Because of those high prevalences those two entities are often associated in same patients (1 to 4% of the general population). This association is then referred to as Overlap Syndrome (CO-OS). Data from observational studies suggest that this association may have an additive or even synergistic negative impact on patient's prognosis. Indeed, in a cohort of patients diagnosed as having a CO-OS, patients who did not receive specific treatment for OSA had a 76% increased risk of death compared to patients treated with continuous positive airway pressure (CPAP) and a 2-fold increased risk of acute COPD exacerbation. In another cohort of patients with both OSA and severe oxygen treated COPD, untreated patients for OSA had a 5-fold increased risk of death compared to patients treated with CPAP. There are strong signals from observational studies in support of a beneficial impact of CPAP therapy on respiratory outcomes in patients with CO-OS. However, those findings are not supported by any controlled study. It is difficult to directly transpose the observational data to current clinical practice in the context of the recent studies on the impact of CPAP on OSA prognosis. Indeed, data from similar observational OSA cohorts have reported a major impact of CPAP on the overall survival and cardiovascular outcomes in patients with OSA. Ten years later, this impact has not been confirmed by several randomized studies. To date, there is no consensus on a systematic screening and, if present, management of OSA in patients with COPD. The need for specific research on that field was emphasized in 2018 in an official American Thoracic Society Research Statement which recommends "randomized trials that compare clinical outcomes among patients with Overlap Syndrome whose OSA is treated to clinical outcomes among patients with Overlap Syndrome whose OSA is untreated".
The goal of the study is to determine the feasibility of a behavioral intervention to improve CPAP adherence among African American patients with obstructive sleep apnea.
