MedicalResearch.com Interview with: Prof. Craig Anderson, PhD Professor of Stroke Medicine and Clinical Neuroscience Medicine, The George Institute for Global Health University of Sydney MedicalResearch.com: What is the background for this study? What are the main findings? Response: We wished to prove whether treatment of obstructive sleep apnea with continuous positive airway pressure (CPAP ) can modify the risk of cardiovascular disease. The is a lot of association data from epidemiological and clinical studies but no large scale international clinical trials assessing the effects of CPAP on the prevention of serious cardiovascular events like heart attack and stroke. Our study in nearly 3000 adults with prior heart attack or stroke and moderate to severe obstructive sleep apnea showed that CPAP treatment did not prevent recurrent cardiovascular events or major cardiovascular risk factors. However CPAP did improve wearers' sense of wellbeing, mood and work productivity.

What are the main findings? Response: CPAP devices, or continuous positive airway pressure devices, are used to treat obstructive sleep apnea, a common condition that causes people to intermittently stop breathing during their sleep. This leads to poor sleep quality and often results in symptoms like excessive sleepiness in the daytime. In the United States, CPAP devices are classified by the Food and Drug Administration as Class II medical devices with possible risks; their sale requires a medical prescription. We were aware of online advertisements for secondhand, used CPAP machines, but we have not seen publications that have analyzed this practice. Once a week, our research team monitored online advertisements for secondhand CPAP devices on Craigslist.org in 18 U.S. cities and areas over a one-month period. During that time, we found 270 advertisements, most of which did not describe who previously had used the device or why it was being sold. Only 5 of the advertisements mentioned anything about the legal requirements of a prescription and 61 percent of the devices included a used mask without information about its age or how it was cleaned. CPAP devices create air pressure and attach to a nose or face mask that delivers that pressure to a patient’s airway, thereby keeping him or her breathing during sleep. The amount of air pressure delivered by the devices is adjusted for each patient and usually is determined by a medical exam that includes an overnight stay in a laboratory. Our study found that most of the Craigslist advertisements failed to mention the devices’ pressure settings—settings that were prescribed for the original owners. The average price for a CPAP device listed on Craigslist was $291, much less than the $600 to $2,000 cost of a new device.

Dr. Larry Chinitz MD Professor of Medicine and Director, Cardiac Electrophysiology NYU Langone Medical CenterMedicalResearch.com Interview with: Dr. Larry Chinitz MD Professor of Medicine and Director, Cardiac Electrophysiology NYU Langone Medical Center MedicalResearch: What is the background for this study? What are the main findings? Dr. Chinitz: The treatment algorithms proposed currently for maintenance of sinus rhythm in patients with atrial fibrillation focus on use of anti-arrhythmic drugs and catheter ablation. Data available to evaluate the effect of modification of known adverse clinical factors on atrial fibrillation recurrence is scant. Obstructive sleep apnea in a known factor associated with both new onset atrial fibrillation as well as its recurrence after catheter ablation. Through a meta-analysis of available data we found that use of continuous positive airway pressure in patients with sleep apnea was associated with a 42% relative risk reduction in recurrence of atrial fibrillation. This effect was similar across patient groups irrespective of whether they were medically managed or with catheter ablation.

Paul M. Macey, Ph.D. Assistant Professor in Residence Associate Dean for Information Technology and Innovations, Chief Innovation Officer UCLA School of Nursing and Brain Research InstituteMedicalResearch.com Interview with: Paul M. Macey, Ph.D. Assistant Professor in Residence Associate Dean for Information Technology and Innovations, Chief Innovation Officer UCLA School of Nursing and Brain Research Institute Medical Research: What are the main findings of the study? Dr. Macey: People with sleep apnea are less able to control the blood flowing to their brain, in particular when they grip tightly, or have their foot put in cold water. We measured changes in blood flowing through the brain using an MRI scanner while people gripped hard, had their foot placed in cold water, and breathed out hard into a tube with a very small hole in it. These activities all lead to more blood flowing to the brain in healthy people, which probably helps protect the cells from being starved of blood and oxygen. However, people with sleep apnea send less blood that the healthy participants during the gripped and cold foot activities. A further important finding is that women with sleep apnea are worse off than men. The female patients showed much weaker blood flow than the males, even accounting for normal differences between men and women.

MedicalResearch.com Interview with: Prof. Mary J Morrell Faculty of MedicineNational Heart & Lung Institute Professor of Sleep & Respiratory Physiology Imperial College, London Medical Research: What are the main findings of the study? Prof. Morrell: Our results showed that when older patients with obstructive sleep apnea were treated with continuous positive airway pressure (CPAP) they had significantly less daytime sleepiness than those not treated with CPAP. A comparison of the costs and benefits of treatment suggested that CPAP would meet the usual criteria for being funded by the NHS.

Rossi” 37134 Verona Italy University of Lund Department of Clinical Sciences Division of Endocrinology CRC, Lund University S-205 02 Malmö Sweden MedicalResearch.com: What are the main findings of the study? Dr. Fava: The main finding of the meta-analysis is that cPAP usage for at least 2 weeks, with respect to either placebo or usual care is associated with a significant reduction in both systolic and diastolic blood pressure. However the effect size of blood pressure reduction is modest.

MedicalResearch.com Interview with: Marc L. Benton, MD, FCCP, FAASM Morristown Medical Center and Atlantic Sleep & Pulmonary Associates, 300 Madison Ave. Third Floor Madison, NJ 07940 MedicalResearch.com: What are the main findings of the study? Dr. Benton:  When compared to a group of matched controls, 12 male golfers who had moderate-severe obstructive sleep apnea syndrome (OSAS) demonstrated statistically significant improvement in their ability to play golf (as measured by changes in the Handicap Index, the standardized indicator of golfing performance) after undergoing CPAP treatment for their condition.  Treatment adherence among the group placed on CPAP was unusually high.
