Obesity Hypoventilation Syndrome(OHS) is a disease characterized by daytime hypercapnia and sleep-disordered breathing without other causes of hypoventilation in individuals with a body mass index above 30 kg/m2. Sources state that obesity is at the basis of the metabolic changes seen in individuals with OHS. Obesity, together with cardiovascular system complications, lung volumes, work of breathing and sleep quality, creating the basis for respiratory problems. In addition, sedentary lifestyle habits, which are common in obese individuals, cause negative effects on exercise capacity and peripheral muscle strength. It has been shown in the literature that decreased exercise capacity due to obesity strongly interacts with the risk of all-cause mortality. As a result of obesity and all this negative picture, impaired emotional state and decreased quality of life are observed in individuals. Numerous studies have shown that obese individuals generally have a low level of physical activity, there is a decrease in peripheral muscle strength, obese individuals are at risk for sleep-related respiratory problems and health-related quality of life is often negatively affected in obese individuals. With these studies, the effects of obesity on individuals have been evaluated with objective evaluation methods. However, the same cannot be said for OHS. It is not clear how exercise capacity, peripheral muscle strength and quality of life parameters, which are known to be negatively affected by obesity, are affected in individuals with OHS. Based on this point, this study aims to investigate whether OHS has an additional effect on exercise capacity, peripheral muscle strength and quality of life in addition to obesity.
Obesity Hypoventilation Syndrome(OHS) is characterized by daytime hypercapnia and sleep-disordered breathing without other causes of hypoventilation in individuals with a body mass index above 30 kg/m2. It is stated that obesity is at the basis of the metabolic changes seen in individuals diagnosed with OHS. Also sedentary lifestyle habits, which are common in obese individuals, cause the risk of sarcopenia due to loss of muscle strength and mass, accumulation of adipose tissue in the body, and decreased exercise capacity. Reduced exercise capacity due to obesity has been shown in the literature to strongly interact with mortality risk. As a result of obesity and all this negative picture, impaired emotional state and decreased quality of life are observed in individuals. Simultaneously, sleep parameters are also negatively affected. In particular, increased adipose tissue leads to loss of muscle mass and strength, increased risk of sarcopenia and sleep-related problems. The association of obesity and sarcopenia is referred to as 'sarcopenic obesity'. Sarcopenic obesity is defined as the coexistence of sarcopenia and obesity. The concept of sarcopenic obesity has recently taken its place in the literature. In particular, there are very few studies on its relationship with sleep parameters. However, while obesity is the basis of OHS, there are no studies on the presence and effects of sarcopenic obesity in this patient group. Based on this point, we aim to investigate the effects of sarcopenic obesity on sleep parameters, exercise capacity and quality of life in individuals with OHS.
COVID-19 has significantly impacted sports globally, with event postponements, training disruptions, and wide-ranging concerns. SARS-CoV-2 infection can result in hyperinflammation and cardiopulmonary changes, with hypoxia as an aggravating sign. Hypoxia triggers complex immunometabolic mechanisms, including activation of HIF-1α and induction of HLA-G expression. Hypoxia training protocols benefit aerobic capacity and sports performance, with potential immunological impact. Studying immunometabolic markers in this context can improve athletic preparation and athletes' general health.
This study was designed as a randomized controlled experimental type in order to determine the effect of slow breathing exercise applied after the procedure on heart rate, blood pressure and quality of life in patients who underwent Primary Percutaneous Coronary Intervention (PCI) I after the diagnosis of ST Elevation Myocardial Infarction (STEMI). Patients who underwent primary PCI due to STEMI in a Training and Research Hospital in Istanbul will constitute the study population. A sample will be formed with a total of 80 patients, 40 experimental and 40 control groups, selected by computer assisted simple randomization method among volunteer patients who underwent primary PCI and met the inclusion criteria. In this study, slow breathing exercise training will be given to the experimental group by the coordinator. In their home followmup after discharge, they will be asked to do slow breathing exercises for 10 minutes twice a day for eight weeks. Data will be collected using the "Patient Information Form", "MacNew Heart Disease Health Related Quality of Life Scale", "VAS Breath Therapy Satisfaction Evaluation Form", "Self-Monitoring Form" and "Patient Follow up Form". Patients will be seen again during the outpatient clinic examination in the fourth and eighth weeks and the effectiveness of slow breathing exercises will be evaluated with data collection forms.
The goal of this clinical trial is to clinically validate a system for the monitoring of patients' respiratory function and automated oxygen treatment proposal using non-invasive ventilation devices in the treatment of intensive care patients with acute or chronic lung diseases exacerbations. Participants clinical parameters will be monitored and samples will be sent to a clinical laboratory for analysis (arterial blood pressure, heart rate, and respiratory rate will be continuously recorded, and FeO2 and CO2 will be measured with the help of an additional sensor).
Determine the incidence of early post-operative hypoventilation in post-anesthesia care unit (PACU) in patients undergoing laparoscopic bariatric surgery under opioid-sparing compared with sevoflurane-based anesthesia.
The goal of this research study is to assess the FDA approved technique for inserting a feeding tube (gastrostomy) along with a breathing tube (tracheostomy) for patients that cannot breathe or eat on their own in the ICU (Intensive Care Unit). All subjects in the study will receive a tracheostomy, but each patient will be randomly assigned a common method for gastrostomy placement. The placement of the tube and tracheostomy will occur as part of normal clinical practice. Researchers will compare subjects in the control group and the intervention group to evaluate the benefits of performing a tracheostomy and gastrostomy tube at the same time. Researchers will also evaluate the likelihood of the PUG procedure decreasing a patient's length of stay in the ICU.
Sleep-disordered breathing (SDB) is prevalent in children and adolescents and untreated SDB impacts key indicators of physical and psychosocial health. Positive airway pressure (PAP) therapy is highly effective for the treatment of SDB and is associated with favorable clinical outcomes but is limited by poor adherence. Emerging literature in adults suggests that intolerance to PAP therapy may be related to coexisting insomnia. However, the presence of insomnia in children with known SDB as well as its impact on PAP adherence have not been explored. This proposal will explore the association of coexisting insomnia on PAP adherence in children with SDB using a cross-sectional study design. The investigators will assess the association between insomnia and PAP therapy adherence, measured as the mean minutes of nightly PAP usage over 6 months of use on objective downloads.
Nearly 25% of Americans die in intensive care units (ICUs). Most deaths in ICUs are expected and involve the removal of ventilator support, or palliative withdrawal of mechanical ventilation (WMV). Prior work by the Principal Investigator (PI) found that patient suffering can be common; with 30-59% of patients going through this process experiencing distress. Thus, experts and national organizations have called for evidence to inform guidelines for WMV. This research study will 1) develop and refine a Comfort Measures Only Time out (CMOT) intervention consisting of a structured time out with check-list protocol for the ICU team (nurse, physician, respiratory therapist) to improve the process of WMV. and 2) Pilot test the CMOT intervention in 4 ICUs (2 medical/2 surgical) among 40 WMV patients.
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.
