Samsung Researchers’ Non-Invasive Blood Glucose Monitoring Method Featured In ‘Science Advances’

With diabetes and its related costs on the rise all over the world, effective blood glucose monitoring is taken into account extra important than ever. While typical strategies have required individuals with diabetes to prick their finger to extract blood drops, non-invasive options, which decrease patients’ pain and BloodVitals home monitor discomfort, have been a long-standing dream in diabetes management. Recently, researchers at the Samsung Advanced Institute of Technology (SAIT), Samsung Electronics, in collaboration with the Massachusetts Institute of Technology (MIT), developed an revolutionary, non-invasive technique for monitoring blood glucose levels that makes use of a technique often called Raman spectroscopy. On January 24, the researchers introduced their findings in Science Advances, a scientific journal from the American Association for the Advancement of Science. Raman spectroscopy is a spectroscopic technique that utilizes lasers for chemical composition identification. Previous studies that utilized Raman spectroscopy for glucose sensing in recent many years demonstrated a functionality to measure glucose mainly by presenting statistical correlations to the reference glucose concentration. However, these research raised questions regarding the effectiveness and accuracy of using Raman spectroscopy for glucose measurement as a consequence of a scarcity of direct proof for glucose sensing. To interrupt by the constraints that arose in prior studies, Samsung’s researchers developed an off-axis Raman spectroscopy system that allows the direct commentary of glucose Raman peaks from in vivo skin. Utilizing this system, they demonstrated one in every of the best prediction accuracies amongst non-invasive technologies. The analysis crew additionally developed an revolutionary approach for BloodVitals home monitor decreasing the results of movement artifacts on glucose sensing in Raman spectroscopy. "Non-invasive blood glucose monitoring has been a topic of great dialogue for decades, and i imagine that our findings will assist guide the direction of future research for non-invasive glucose sensing," stated Dr. Sung Hyun Nam, Master at SAIT’s Mobile Healthcare Lab.

She labored as a communications skilled for health nonprofits and the University of Toronto’s Faculty of Medicine and Faculty of Nursing. Hypoxia is a situation that happens when the body tissues do not get ample oxygen supply. The human physique depends on a steady circulate of oxygen to function properly, and when this provide is compromised, it might probably considerably have an effect on your well being. The symptoms of hypoxia can differ but commonly embody shortness of breath, confusion, dizziness, and blue lips or fingertips. Prolonged hypoxia can lead to lack of consciousness, seizures, organ harm, or dying. Treatment depends upon the underlying trigger and may embrace medicine and oxygen therapy. In extreme instances, hospitalization could also be needed. Hypoxia is a relatively frequent condition that may have an effect on folks of all ages, especially those who spend time at high altitudes or have lung or heart conditions. There are four main forms of hypoxia: hypoxemic, hypemic, stagnant, and histotoxic.



Hypoxia types are categorised based on the underlying trigger or the affected physiological (body) process. Healthcare suppliers use this data to determine probably the most acceptable treatment. Hypoxemic hypoxia: Occurs when there may be inadequate oxygen within the blood, and due to this fact not enough oxygen reaches the body's tissues and very important organs. Hypemic (anemic) hypoxia: Occurs when the blood does not carry ample amounts of oxygen attributable to low red blood cells (anemia). Because of this, the physique's tissues do not receive sufficient oxygen to function usually. Stagnant (circulatory) hypoxia: Occurs when poor blood circulation prevents ample oxygen supply to the physique's tissues. This may increasingly occur in a single physique space or all through the complete physique. Histotoxic hypoxia: Occurs when blood circulate is normal and the blood has adequate oxygen, however the body's tissues cannot use it effectively. Hypoxia signs can differ from person to individual and should manifest in a different way relying on the underlying cause.



Symptoms of hypoxia can come on out of the blue, but more usually, they are subtle, gradually growing over time. There are a lot of causes of hypoxia, including medical circumstances that affect the guts or lungs, sure medications, and environmental components. Each sort of hypoxia has unique causes. Hypoxic hypoxia happens when there is a diminished oxygen provide to the lungs. Hypemic (anemic) hypoxia happens when the blood can't carry adequate quantities of oxygen to the physique tissues, usually attributable to low numbers of red blood cells. Stagnant (circulatory) hypoxia happens when poor blood circulation impairs oxygen delivery to tissues. Histotoxic hypoxia occurs when the blood has sufficient oxygen levels, but the cells can not successfully use oxygen. Hypoxia can happen to individuals of all ages, though sure risk components can enhance the likelihood of experiencing it. To diagnose hypoxia, your healthcare provider will consider your medical history, carry out a physical exam, and order diagnostic exams. Diagnostic checks may help them assess the severity of hypoxia and identify the underlying cause.
