The number of patients assigned to medical residents and the complexity of care patients require has just as much impact on residents’ training as the number of hours they work, according to a study published by researchers at the University of Chicago Medical Center in the September 10, 2008 issue of JAMA.
The study is believed to be the first of its kind using information gathered objectively from medical residents who work long shifts as part of their training.
Research engineers and sleep medicine specialists from two Michigan universities have joined technical and clinical hands to put innovative quantitative analysis, signal-processing technology and computer algorithms to work in the sleep lab. One of their recent findings is that a new approach to analyzing sleep fragmentation appears to distinguish fibromyalgia patients from healthy controls.
Joseph W. Burns, a research scientist and engineer at the Michigan Tech Research Institute (MTRI); Ronald D. Chervin, director of the University of Michigan’s Michael S. Aldrich Sleep Disorders Laboratory; and Leslie Crofford, director of the Center for the Advancement of Women’s Health at the University of Kentucky, report the results of their study in the August 2008 issue of the journal Sleep Medicine.
A study published in the August 15, 2008 issue of the Journal of Clinical Sleep Medicine shows that surgical weight loss results in an improvement of obstructive sleep apnea (OSA), but most patients continue to have moderate to severe OSA one year after undergoing bariatric surgery. Results of this study suggest that it is the severity of the condition, rather than a patient’s pre-surgical weight, that determines if obstructive sleep apnea will be resolved.
Results show that bariatric surgery reduced body mass index (BMI) from an average of 51 to 32 in 24 adults with obstructive sleep apnea.
Researchers found that patients with obstructive sleep apnea, who were compliant with their CPAP therapy, experienced an average 2mm/Hg drop in both systolic and diastolic blood pressure at the end of the year when compared to patients who did not use the CPAP machine.
Nasal surgery to remove obstructions from the airway is associated with improvements in quality of life for patients with obstructive sleep apnea and symptoms of nasal blockages.
Obstructive sleep apnea (OSA) is characterized by episodes of partial or complete blockage of the airway during sleep, leading to snoring and daytime sleepiness. Blockage of the nasal passages also is common in OSA patients, causing fragmented sleep and leading to daytime tiredness and poor quality of life.
In a study that examined the relationship between race, menopausal status and symptoms of obstructive sleep apnea (OSA), middle-aged black women were found to be more likely to experience OSA symptoms than their white counterparts.
The U.S. Food and Drug Administration (FDA) has requested that all manufacturers of sedative-hypnotic drug products, a class of drugs used to induce and/or maintain sleep, strengthen their product labeling to include stronger language concerning potential risks.
These risks include severe allergic reactions and complex sleep-related behaviors, which may include sleep-driving. Sleep driving is defined as driving while not fully awake after ingestion of a sedative-hypnotic product, with no memory of the event.

As of May 2, 2009 at 9:47 p.m. (-0500) (ET), the U.S. population
was 306,340,710. Sleep researchers estimate approximately seven percent
of the population suffers from obstructive sleep apnea. Using that
estimate, there are potentially 21,443,850 apneics in the U.S.
