Filter by:This study focuses on the prevalence and identification of kidney disease among participants of the WTC Health Program and the study team are planning to assess kidney disease in a multi-factorial manner. The first aim of this study is to correlate kidney dysfunction with 9/11 exposure, and the study team predicts that exposure to 9/11 is an independent risk factor in kidney disease among the WTC Health Program participants. Secondly, the study team proposes that a well-established WTC-related condition, obstructive sleep apnea (OSA), is independently associated with kidney disease. In addition, the study team believe there is a temporal causative relationship between evidence of kidney disease and the severity of OSA. Finally, the last aim is to further identify and explore potential mechanisms and phenotypes of kidney disease in participants of the WTC Health Programs. Regardless of whether the analyses support or reject these hypotheses, the findings will be of equally great public health importance. Successful completion of the proposed research would address a critical knowledge gap regarding the risk of kidney damage among this group of patients, and would inform future mechanistic studies with the potential to impact prevention.
The investigation is a prospective, randomized, single blinded, crossover study. The investigation is designed to evaluate the performance, comfort and ease of use of the F&P Trial Full Face Mask Seal amongst Obstructive Sleep Apnea (OSA) participants. A total number of 40-45 OSA participants will be recruited for the trial by the investigation site
This study aims to determine the prevalence and prognosis of heart failure with preserved ejection function (HFpEF) among patients being assessed for sleep disordered breathing (SDB).
Obstructive sleep apnea is defined as a repetitive collapse of the pharynx during sleep (Malhotra, et al. 2012) which cases intermittent hypoxia. Snoring, witnessed apnea, fatigue and morning headache are symptoms of the disease which has severe health effect (Malhotra. et al. 2012) including increased mortality risk (Ensrud. et al. 2012) and effects on quality of life (Kuhn. et al. 2017). Obesity, male sex and age are all risk factors for obstructive sleep apnea (Schwartz. et al. 2010, Edwards. et al. 2010) . Bariatric surgery is known to be a good treatment to achieve a sustained weight loss but the long term effects of bariatric treatment of obstructive sleep apnea is not well studied. The aim of this study is therefore to study the long effects of bariatric surgery as a treatment for obstructive sleep apnea and to find predictors that can be used to predict the severity of the disease.
Obstructive sleep apnea (OSA) results in vascular dysfunction, which increases the risk of cardiovascular disease. In contrast, exercise confers cardioprotection through improvements in vascular health. This proposal evaluates whether the beneficial effects of exercise on vascular function are attenuated in obese individuals suffering from untreated OSA.
This study will compare the effectiveness of the two leading oral appliances (OAs) designs for the treatment of severe obstructive sleep apnea in overweight adults. The effectiveness of OAs has come under question since different designs are combined in evaluating treatment efficacy, for example when comparing them to continuous positive airway pressure Due to the wide range of reported efficacy (53 to 90%), it is of great value to identify the most effective design to guide sleep practitioners and patients.
During induction of anesthesia in children, the investigators have observed significant variability in mask holding technique at our institution among different anesthesia practitioners. Some hold the face mask using one hand and others use two hands. The aim of our study is to comparatively evaluate the extent of airway obstruction in children whilst anesthetic mask is held with one hand with jaw thrust versus mask held using two hands with chin lift by anesthesia provider during induction of anesthesia in children.
Continuous positive airway pressure (CPAP) is the first choice of treatment for moderate to severe obstructive sleep apnea syndrome (OSAS). Although adherence is critical for achieving a good treatment effect, and early intervention if treatment problems emerge is important for achieving good adherence, information on patient compliance is usually based on assessment of the first few weeks of treatment. Telemedicine technology allows for monitoring of CPAP pressure, air leaks, apnea-hypopnea index (AHI) and compliance on a daily basis and could therefore be an option allowing for adequate support and quick response if a patient has problems with the treatment. In addition, improving early experiences of CPAP, identifying patients in need of more intensive support could potentially improve adherence but also reduced cost of care, and increased patient satisfaction. The proposed study will recruit 200 OSAS patients starting CPAP treatment; 100 patients randomized to afterwards receiving telemonitoring in combination with telephone calls, and 100 patients randomized to receiving usual office visits. All patients will in addition answer questionnaires on sleep and health, quality of life, and patient satisfaction after the first CPAP information visit and then again after 6 months of treatment. At time of follow-up all patients will also answer questionnaires on side effects of CPAP. Health economic variables will also be measured throughout the testing period. The study will provide valuable information regarding benefits of telemonitoring in clinical work with CPAP therapy. Implementation of telemedicine-based monitoring of CPAP therapy may be an important part of increasing adherence among patients but also in the development of a more cost-effective care as it can provide clinics with increased treatment capacity and follow-up of both new and established patients. It would further improve the care for these patients who often have a lifelong treatment, which aims to reduce the risk of developing cardiovascular disease or premature death.
This is a single-arm study involving the use of a high resolution manometry (HRM) diagnostic device that is not utilized in any clinical decision-making processes. All patients scheduled for DISE as part of their regular clinical care will be screened for enrollment via described inclusion and exclusion criteria.
Oral appliances (OA) have emerged as an alternative to continuous positive airway pressure (CPAP) for obstructive sleep apnea (OSA) treatment. The most commonly used OA reduces upper airway collapse by advancing the mandible (mandibular advancement devices, MAD). There is a strong evidence base demonstrating that MADs improve OSA in the majority of patients, including some with more severe disease. However, MADs are not efficacious for all, with approximately one-third of patients experiencing no therapeutic benefit. Patients often prefer MADs to gold-standard CPAP treatment. Head-to-head trials confirm CPAP is superior in reducing OSA parameters on polysomnography; however, this greater efficacy does not necessarily translate into better health outcomes in clinical practice. Comparable effectiveness of MADs and CPAP has been attributed to higher reported nightly use of MADs, suggesting that inferiority in reducing apnoeic events may be counteracted by greater treatment adherence. The MAD in study, called Bite-Velo Linguale (BVL), features a novel monobloc device including a tongue retainer, a suction cavity that maintains the tongue down onto the mouth floor in order to prevent it from raising towards the hard palate, and therefore increasing the retro lingual aerial space. Its design requires the presence of only four occlusal points, allowing for a direct anchorage onto the mandibular bone, thus reducing the risk for occlusal changes, tooth loosening and the development of an anterior cross bite, which represent some of the major long-term adverse effects of oral appliances. MADs are generally well tolerated, although short-term adverse effects during acclimatization are common. Long-term dental changes do occur, but these are for the most part subclinical and do not preclude continued use. The BVL in study features technological advances aimed at preventing long-term dental changes, as well as improving tolerability and easiness of use.
