To disrupt the way health is monitored

After battling it out on Centre Stage, the audience cast their final votes. A moment of waiting and… we have it! Congratulations to Nutrix, who were crowned on Centre Stage at Web Summit 2019 tech conference this week, for their innovative solution to measuring glucose in the blood without needles. [1]

Diabetes prevalence

Firstly, we will look at the data. It is estimated that 415 million people are living with diabetes in the world, which is estimated to be 1 in 11 of the world’s adult population. 46% of people with diabetes are undiagnosed. The forecast is as follows: the figure is expected to rise to 642 million people living with diabetes worldwide by 2040. [2][3]

 

Nutrix’s vision

This year’s winner of Web Summit PITCH, powered by Siemens is going to disrupt the way health is monitored. Today it is only when you are unwell that you get the information from your doctor. Nutrix wants to give the people a chance to monitor this before. [4]

Future of glucose monitoring

Currently, Nutrix is developing a high tech nanosensor that is placed on the tooth which detects glucose level in the saliva and transfers information to an external app. Nutrix is invisible, non-invasive, and patient-friendly. Additionally, it will track food intake and provide valuable information for the patient and artificial pancreas algorithms. [4]

Progress and development

Nutrix is being incubated at University Children’s Hospital Basel and developed at CSEM lab a private, non-profit Swiss research and technology organization.

 

Advantages

It is not the mere fact of monitoring blood glucose that arouses the greatest enthusiasm. It turns out that you can control the level of other chemicals in the same way. The technology proposed by the startup becomes useful not only for people who are sick and their lives depend on the level of specific substances in the blood. It is also an effective way to control the compounds consumed every day.

Correct blood sugar is important not just for diabetics. Fluctuations in blood sugar levels can contribute to weight gain and fat deposits all over the body. Therefore, it is a mistake to think that glucose levels should be controlled only by those who have diabetes.

So we get to the point where we can confidently say that the use of Nutrix is ​​an effective way to prevent civilization diseases.

Finally, Nutrix has a long-term vision that goes further than just glucose. This is their current focus, but ultimately the company wants to go into how to monitor the reaction of the immune system. [5]

 

Diabetes and the environment

There are more advantages. Blood glucose test strips are the basic equipment of every diabetic. The strips are used for self-monitoring of blood glucose. They are used once and then discarded. [6]

According to the Environmental Protection Agency, lancets are medical wastes called sharps. Sharps can be dangerous to that handling garbage if they are thrown in the regular trash. What is more, many people do not pay attention to the safe disposal of their medical waste. The use of a nanosensor eliminates the need for strips and reduces harmful effects on the environment. [7]

 

Cost-effectiveness

An additional advantage of eliminating the need to use measuring instruments is not only the reduction of harmful effects on the environment. The less intrusive (read needleless) device will be sold at half the price of existing devices.

Invisible, non-invasive, patient-friendly. Good for the Earth and still less costly. There is nothing else to do but observe how Nutrix revolutionizes medicine. Soon, checking how many chemicals you ate during the day will be a matter of opening the app.

Can you imagine all of that data on your mobile device’s screen without the need of doing blood tests?

Smart pills to help diabetics?

Scientists from MIT (Massachusetts Institute of Technology), Harvard Medical School, Brigham and Women’s Hospital and Novo Nordisk collaborate on creating a new kind of drug which aim is to make diabetics’ lives easier and less painful.

Nowadays people suffering from diabetes have to inject insulin multiple times per day to maintain a proper blood glucose level. For the last 100 years scientists tried to find a way to make insulin possible to be taken orally, which is quite a challenge, because many pharmaceutical compounds can’t survive the stomach’s harsh, acidic environment.

The new device created by previously mentioned scientists is about to finally allow diabetics to put injections off and make the whole process a lot easier. The smart pill works by attaching itself to the inside of the stomach and then injecting a payload through the gastric wall. Once the sugar glass that surrounds it is dissolved by acid in the stomach a tiny needle is released and a patient gets a proper dose of insulin.

The current injection is not the most comfortable process because of the pain related to inserting the needle into veins, right? Taking this smart pill orally means the injection will be done inside your stomach, which exactly means that you will not feel any pain. Why? According to Robert Langer, coauthor of the whole project, there are no pain receptors within the gastrointestinal tract.

Moreover, the shape of the pill is inspired by the shape of a leopard tortoise’s shell, which automatically self-rights no matter how it lands – that kind of structure ensures that the device will attach to the gastric wall every time. It’s worth noting that the whole project is still at the proof-of-concept stage and has only been tested in animals, so the device won’t be available in the nearest future.

So, what are your thoughts on this topic? Do you think that in the futue smart pills will be a common thing? Let me know down below!

LONGEVITY CLOSER THEN WE THINK?

Humans are thinking about immortality since the dawn of time. Thanks to the current progress in technology we are witnessing a discovery that potentially could rewrite our lives. Senolytics are new class of drugs which may provide us with a better, healthier lives.

Judith Campisi is a professor at the Buck Institute for Research on Aging in Novato, California, and cofounder of a company called Unity Biotechnology in 2011. She is known as a leading figure in the biology of ageing since the early 1990s, when her research revealed that cells enter a phase known as senescence that prevents them from becoming cancerous.

Her research is currently focused on the role of cellular senescence in cancer and other age-related diseases. So, what cellular senescence basically means? According to Wikipedia, it is „one phenomenon by which normal cells cease to divide”. In 1960’s, Leonard Hayflick and Paul Moorhead found out that normal human fetal fibroblasts in culture reach a maximum of approximately 50 cell population doublings before becoming senescent. This phenomenon was called Hayflick limit and is known or overturning a 60-year-old dogma which maintained that all cultured cells are immortal.

It is worth noting that senescent cells in some point come to the kind of twilight state where they are still active but no longer dividing. Campisi’s and other scientists’ researches showed that this was a ‘strategy’ of the evolution process to derail incipient cancer cells, which are known to spread thanks to the cells division.

Now, Campisi is conducting researches on new class of drugs called senolytics, which eliminate senescent cells and restore more youthful characteristics (in animal experiments). The company called Unity Biotechnology, which she cofounded in 2011, launched a human trial of its first senolytic drug last July.

This actions can cause a moral dilemma whether we should live longer than we already do. Campisi points out that we should not confuse aging and death. She expects that, thanks to senolytics, we will be able to extend our “health span”, which basically means that there is a possibility that we will extend the duration of good health condition of our bodies while living the same amount of time as we currently do.

Today we can observe a debate about the limit to the human life span. Some say it can be 110 years, others claims it to be 150 years. Speaking of this case, Campisi provides us with examples such as world record for extending the life span of a little worm called C. elegans, which is 10-fold. On the other hand, most of the really intensive experiences extend mouse life span (which is about 97% genetically identical to human being) by 20-30%. In the end we just simply do not know what the maximum life span of human being, but there is a possibility that we can extend it even more than we already did, for example thanks to the discovery of vaccines.

 

So, what are your expressions on this topic? Would you like to live longer? Why? Or why not? Would you like to extend your “health span” or you believe that ageing is a necessary part of our lives? Let me know in the comment section!

Are You ready to give Your blood away?

Couple days ago Google (now Alphabet) sent a patent query about the “needle-free blood draw”. The idea is to patent a system of blood draw and insert it in wearable electronics. According to the Alphabet the procedure lasts for couple seconds and pain-free (system sends a gas into a barrel containing a micro-particle that pierces the skin. Once blood is released from the skin, it’s sucked up into the negative pressure barrel.

The Company announces that it enables to collect small portion of blood enough to conduct a glucose  test, so it makes, if released, be a indispensable for diabetics.

Indeed the number of people with diabetes is huge in US and it can open a valuable door for new business. But again and again we are prompted to raise the personal data issue: what will be happening with blood samples? Where the base of samples will be stored? Just inside the device?

What Do You think, guys?
