A new wearable smart device to measure sugar levels, stress and inflammation from the sweat
The scientists from the University of Texas, United States had developed a new wearable device to measure sugar or glucose levels in sweat for every one hour, up to one week costing between 10 and 15 cents. The inbuilt sensor in the wearable device helps diabetic individuals in managing their symptoms and also helps healthcare professionals in providing better treatment options to the patients. The device also measures two other body biomarkers, stress levels with cortisol and inflammation with interleukin-6 (IL-6) apart from sugar or glucose levels.
Authors of the study say cortisol levels increase with chronic stress. The increased cortisol levels increase insulin resistance. Increased insulin resistance keeps the blood sugar or glucose at higher levels leading to type 2 diabetes (T2D) condition. The body organs will be affected with inflammation associated with type 2 diabetes (T2D) condition.
The device was designed to work on all skin types without sacrificing its performance as it uses a gel, known as an ionic liquid, which helps in stabilizing the skin surface microenvironment. The wearable device can be connected to a smartphone App and data can be sent to healthcare professionals. Lead author of the study was Shalini Prasad, Associate professor of bioengineering, the University of Texas, Dallas, United States.
Obstructive sleep apnea or apnoea (OSA) increases the risk of diabetic retinopathy in patients with type 2 diabetes
A study by the researchers at University of Birmingham, Birmingham, United Kingdom shows an increased risk of sight-threatening diabetic retinopathy with obstructive sleep apnea or apnoea (OSA) in type 2 diabetes (T2D) individuals. They say obstructive sleep apnea (OSA) is an independent predictor for the progression of diabetic retinopathy (an eye disease). In the current study, researchers conducted 43 months average follow-up studies on 230 patients with type 2 diabetes (T2D).
Researchers found that retinopathy condition was higher in patients with obstructive sleep apnea or apnoea (OSA) compared in those individuals without obstructive sleep apnea (OSA). They found a higher risk of the development of severe retinopathy among type 2 diabetes (T2D) patients with obstructive sleep apnea (OSA). But the study shows risk reduction to the development diabetic retinopathy associated with obstructive sleep apnea with the use of CPAP machines.
They advise healthcare professionals to test for obstructive sleep apnea (OSA) as this condition is common among type 2 diabetes (T2D) individuals. The corresponding author of the study was Doctor Abd A Tahrani, NIHR Clinician Scientist, the University of Birmingham. The study findings were published June 8, 2017, in the American Journal of Respiratory and Critical Care Medicine. Title of the article was "Obstructive Sleep Apnoea and Retinopathy in Patients with Type 2 Diabetes: A Longitudinal Study".
CPAP : The CPAP machine is a small machine which helps individuals with obstructive sleep apnea (OSA) to breathe easily during sleep. They eliminate snoring and prevents the collapse of airway and "apneic" or breathing stoppage events while breathing by using continuous positive airway pressure during sleep. There are no serious side-effects with the usage of CPAP machines. But some patients may nasal congestion, rhinitis (hay fever, a pollen allergy) or a runny nose.
