Summary
Erectile dysfunction is common in men with obstructive sleep apnea, due to vascular damage, which leads to heart attack. CPAP is the preferred treatment for patients with OSA because of its well-proven ability to decrease sleepiness and improve blood pressure control. This study will establish if CPAP can also improve erectile and vascular endothelial dysfunction. These results will shed light on the mechanisms that underpin the relationship between OSA and Erectile Dysfunction.
Chronotherapy Of Hypertension In Obstructive Sleep Apnoea

Summary
Obstructive Sleep Apnoea (OSA) is linked with excess cardiovascular disease, and this is partly attributed to increased high blood pressure (hypertension). Understanding how both conditions exacerbate hypertension and whether blood pressure control can be improved by altering the time that medication is taken will lead to improvements in health.
Cardiometabolic Changes After Continuous Positive Airway Pressure Treatment For Obstructive Sleep Apnea

Funding Amount
$82,421.00
Summary
CPAP is the preferred treatment for patients with OSA because of its well-proven ability to decrease sleepiness and improve blood pressure control. This study will definitively establish if CPAP can also improve markers of cardio-metabolic health, such as visceral fat, insulin sensitivity, central blood pressure and arterial stiffness. The results of the study will shed light on the broader health consequences of OSA and contributes to the development of more targeted treatment strategies.

Optimising Non-invasive Ventilation At Birth For Preterm Infants

Summary
Infants born very premature require respiratory support at birth to make the transition to newborn life. As these infants are very immature and prone to injury, modern respiratory care strategies utilise the least invasive approaches mainly applied using a facemask. However, we have discovered that the larynx is closed at birth and thereby prevents air from entering the lung. This application is focussed on optimising the efficiency of facemask ventilation at birth and stimulating breathing.
A Prospective Multicentre Randomized Study To Evaluate The Impact Of OSA Treatment With CPAP On Atrial Electrical And Structural Substrate And On Long Term Maintenance Of Sinus Rhythm Following Catheter Ablation Of Atrial Fibrillation

Funding Amount
$128,224.00
Summary
Atrial fibrillation(AF) is the commonest heart rhythm disorder causing stroke, heart failure and increased mortality. Similarly, obstructive sleep apnea(OSA) is increasingly recognised as a modern epidemic. Epidemiological data have demonstrated an independent association between the two conditions. We will conduct a prospective multicenter randomized study to evaluate the impact of OSA treatment on: (i)maintenance of sinus rhythm after catheter ablation of AF, (ii)atrial structure and function
Treating Insomnia In Patients With Co-existing Obstructive Sleep Apnea

Summary
Obstructive sleep apnea (OSA) and insomnia commonly coexist in the same patient, and can affect how patients adhere to treatment for their OSA. Insomnia can be effectively treated by a clinical psychologist using a technique known as cognitive behaviour therapy (CBT), but it is currently unclear whether this is effective in patients who also have OSA. This research project will investigate whether treatment of insomnia using CBT in patients who have OSA will improve health outcomes.
