Many people rely on continuous positive airway pressure (CPAP) machines as a safe and effective treatment for sleep apnea. But a new case report describes a rare complication a lingering inflammatory disease of the lungs, apparently related to the use of contaminated well water in a CPAP machine. The report appears in the December Southern Medical Journal, official journal of the Southern Medical Association. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health, a leading provider of information and business intelligence for students, professionals, and institutions in medicine, nursing, allied health, and pharmacy.
Falls among elderly people are significantly associated with several classes of drugs, including sedatives often prescribed as sleep aids and medications used to treat mood disorders, according to a study led by a University of British Columbia expert in pharmaceutical outcomes research. The study, published Nov. 23 in the Archives of Internal Medicine, provides the latest quantitative evidence of the impact of certain classes of medication on falling among seniors. Falling and fall-related complications such as hip fractures are the fifth leading cause of death in the developed world, the study noted. Antidepressants showed the strongest statistical association with falling, possibly because older drugs in this class have significant sedative properties.
It seems obvious that naturally waking up from sleep and being startled by something in the environment are two very different emotional states. However, the neuroscience that underlies these different forms of arousal has, for the most part, remained a mystery. Now, new research published by Cell Press in the November 25 issue of the journal Neuron demonstrates that there are at least two completely separate and independent forms of arousal in fruit flies. The study answers critical questions about how the nervous system processes arousal and may even shed some light on the neurobiology of human affective disorders, such as attention-deficit hyperactivity disorder (ADHD).
Hebrew University, US Scientists Find Clue To Mystery Of How Biological Clock Operates On 24-hour Cycle
How does our biological system know that it is supposed to operate on a 24-hour cycle? Scientists at the Hebrew University of Jerusalem have discovered that a tiny molecule holds the clue to the mystery. Human as well as most living organisms on earth possess circadian a (24-hour) life rhythm. This rhythm is generated from an internal clock that is located in the brain and regulates many bodily functions, including the sleep-wake cycle and eating. Although the evidence for their existence is obvious and they have been studied for more than 150 years, only recently the mechanisms that generate these rhythms have begun to be unraveled. A researcher of the Alexander Silberman Institute of Life Sciences at the Hebrew University, Dr.
Patients often complain that getting a good night's sleep or a bit of peace and quiet in hospital can be difficult. But a study published in the December issue of the Journal of Clinical Nursing has shown that adopting some simple measures can reduce peak noise levels on hospital wards by just under 20 per cent. UK researchers from Newcastle upon Tyne audited average decibel levels before and after a noise reduction intervention programme on three wards with a total of 92 beds - a surgical ward, medical ward and orthopaedic ward. Forty-six ward staff - just over 51 per cent of the total - took part in the initiative, along with five members of the multi-disciplinary team, including a physiotherapist and junior doctors.
ImThera Medical, Inc. today announced that two patients have been surgically implanted with ImThera's aura6000™ neurostimulation device for treating tongue-based Obstructive Sleep Apnea (OSA). Patients are being enrolled in ImThera's pilot clinical investigation in Belgium with the first results expected to be published in the first half of 2010. The patients were implanted with the aura6000, during which the hypoglossal nerve was briefly stimulated to verify system and nerve integrity. One week post- surgery, the patients underwent an in-laboratory Polysomnography (PSG) titration process during which stimulation parameters were determined in order to maintain proper tongue position and to provide an open airway during sleep.
