Risk of osteoporosis increased in obstructive sleep apnoea patients

A diagnosis of obstructive sleep apnoea (OSA) may raise the risk of osteoporosis, particularly among women or older individuals, according to a new study. OSA is a condition that causes brief interruptions in breathing during sleep. If left untreated, OSA can raise the risk for stroke, cardiovascular disease and heart attacks. New research shows that OSA may also increase the risk of osteoporosis.

Uncovering sleep apps; Knowing the limitations

What is happening in YOUR sleep? How can you really know? Ever thought of using a sleep app? There are some misunderstandings to what data is relevant when using sleep apps, so understanding the limitations are IMPORTANT. It is always recommended to follow up with a sleep study to be sure nothing is missed.

Not getting enough sleep can lead to decreased cognitive performance

With people living longer in many societies, the cognitive decline that often accompanies the ageing process is of growing concern. Duration of sleep appears to be closely associated with cognitive decline. Interestingly, sleep deprivation at midlife can influence cognitive functioning during old age. Various brain regions are more susceptible to atrophy as we age. The lateral ventricles are one such brain region and enlargement of the ventricles have been linked to cognitive decline in older adults.

Dear Doctors,

Welcome to the latest edition of the TSGQ E-Newsletter! This month, you will find information on:

    • Sleep duration and age related changes in brain structure and cognitive performance
      With an increasingly older population there has been considerable interest in identifying modifiable risk factors that negatively affect brain structure and cognitive functioning associated with age.
    • Stress and insomnia
      It is well established that stressors can lead to sleep disturbance. Stress exposure has also been shown to be a significant predictor of insomnia. With every additional stressor the risk of developing insomnia increases significantly by 19%.
    • Correlation between obstructive sleep apnoea and erectile dysfunction
      Many male patients with obstructive sleep apnoea also suffer from erectile dysfunction, suggesting a causative link between the two disorders.
    • The impact of the provision of home based sleep studies in Australia
      Provision of sleep studies (Polysomnography) in Australia has nearly doubled since the introduction of publicly funded in-home portable sleep monitoring under the Australian national Medicare program available to all Australian citizens in 2008.
    • Innate immunity in the lung regulates the development of asthma
      A recent review by DeKruyff et al, published in Immunological Reviews July 2014, focuses on innate immune mechanisms that have evolved which can lead to lung inflammation and asthma. These innate mechanisms include a role for two incompletely understood cell types, invariant natural killer T cells and innate lymphoid cells.

Sleep duration and age related changes in brain structure and cognitive performance
With an increasingly older population, cognitive decline associated with aging and neurodegenerative disease has become a mounting problem. Changes in brain structure can precede the clinical presentation of cognitive deterioration or dementia by several years. In view of that there is considerable interest in identifying modifiable risk factors that negatively affect brain structure and cognitive functioning.

Stress and insomnia
In the latest issue of SLEEP; a recent epidemiological study assessed the relationship of stress and insomnia with specific consideration to the moderators and mediators relating to stressful events. Clinical insomnia in the general population has a prevalence of 4-22%. It is well established that stressors can lead to sleep disturbance but stress exposure can be shown to be a significant predictor of insomnia (9.1%). With every additional stressor the risk of developing insomnia increases significantly by 19%. The odds of developing insomnia were shown to be 1.4 times higher in women than men.

Correlation between obstructive sleep apnoea and erectile dysfunction 
It has been estimated that 10-60% of males with obstructive sleep apnoea (OSA) also suffer from erectile dysfunction (ED). OSA is strongly associated with an increased risk of cardiovascular mortality, whilst ED has been proposed as a marker for underlying cardiovascular problems. Therefore, it can be implied that there may be a common pathophysiological mechanism for the two disorders. There are various possible theories on how OSA can lead to ED. These include endothelial dysfunction, hormonal alteration, and hypoxia.

The impact of the provision of home based sleep studies in Australia
The high prevalence of obstructive sleep apnoea (OSA) and increasing awareness of its potential health consequences has placed significant pressure on laboratory-based sleep services leading to growing waiting lists and delays in diagnosis and treatment. Consequently there has been increasing interest in the use of portable sleep monitoring. Provision of sleep studies (Polysomnography) in Australia has nearly doubled since the introduction of publicly funded in-home polysomnography (PSG) under the Australian national Medicare program available to all Australian citizens in 2008. The state of Queensland remains the leading jurisdiction per 100,000 Medicare enrolees for accessing Medicare-funded PSG.

Innate immunity in the lung regulates the development of asthma
The lung, while functioning as a gas exchange organ, encounters a large array of environmental factors, including particulate matter, toxins, reactive oxygen species, chemicals, allergens, and infectious microbes. To rapidly respond to and counteract these elements, a number of innate immune mechanisms have evolved that can lead to lung inflammation and asthma, which is the focus of a review by DeKruyff et al, published in Immunological Reviews July 2014.

Now providing Rhinomanometry as part of our services
 
Inclusive in our services now and part of regular diagnostic and home based sleep studies is the use of Rhinomanometry to further help diagnose any pre-existing nasal obstruction that might require further attention. Rhinomanometry is a diagnostic tool that is used to differentiate nasal obstruction versus mucosa by conducting a test for nasal airway resistance (NAR) before and after topical decongestant. Clinical Rhinomanometers calculate NAR by measuring flow and the pressure producing that flow.
 
At no extra cost to patients, we are happy to continue providing premium care and health diagnosis.
