Temporary Tattoo Instead Of Finger Prick For Diabetics

Temporary Tattoo Instead Of Finger Prick For Diabetics

Diabetics may not have to prick their fingers with a needle to monitor their glucose levels in the near future. Researchers at the University of California, San Diego have discovered a way to test and monitor glucose levels by using a small, stick-on temporary tattoo.

Globally, diabetes is one of the leading causes of death. According to the Centers for Disease Control and Prevention (CDC), close to 29.1 million people in the United States have diabetes. Moreover, 1 out of 4 people do not know they have the disease. This is why the recent scientific advancement and discovery will be a most welcome change for existing and future diabetics.

Currently, diabetics manage this most unfortunate condition by painfully getting blood samples from their fingers. Diabetics use the traditional method of monitoring their glucose levels to prevent problems associated with diabetes by sticking their fingers with a small needle multiple times throughout the day.

Diabetics Welcome This New Discovery

Recently, a University of California, San Diego graduate student named Amay Bandodkar created an electronic device, which has the potential of replacing the traditional methods of monitoring glucose levels in diabetics. This innovative device is made up of an electronic sensor, with interwoven electrodes printed on tattoo paper.

The way it works is quite extraordinary. Diabetics can simply place the temporary tattoo on their arm and the device measures the patient’s glucose levels continuously throughout the day.

Creator Amay Bandodkar provided EurekAlert more information about his new invention.

“The readout instrument will also eventually have Bluetooth capabilities to send this information directly to the patient’s doctor in real-time or store data in the cloud.”

He added, “Presently the tattoo sensor can easily survive for a day. These are extremely inexpensive, a few cents, and hence can be replaced without much financial burden on the patient.”

Bandodkar and a team of nanoengineers at the university developed and tested this amazing device in Professor Joseph Wang’s laboratory at the NanoEngineering Department and the Center for Wearable Sensors at the Jacobs School of Engineering at UC San Diego. The team was able to provide documented evidence that the electronic sensor will function as intended and work at measuring glucose levels.

Researchers at the university performed an early trial on seven men and women between the ages of 20 and 40. The participants were not diabetics; however, the test results revealed the temporary tattoo was just as accurate as a finger-prick test. Additionally, the volunteers reported they hardly felt anything while wearing the device; they only felt a mild tingling sensation for about 10 seconds.

How The Tattoo Works At Managing Diabetes

The researchers developed the device to apply a very gentle electric current to the skin for about 10 minutes. Sodium ions that carry glucose are located in the fluid between skin cells. Glucose is drawn out and flows to the temporary rub-on tattoo. An electronic sensor in the tattoo measures an electrical charge produced by the glucose.

Professor Wang and the team published their study in the journal of Analytical Chemistry. Bandodkar explained more about the flexible device for diabetics.

“The concentration of glucose extracted by the non-invasive tattoo device is almost hundred times lower than the corresponding level in the human blood. Thus we had to develop a highly sensitive glucose sensor that could detect such low levels of glucose with high selectivity.”

Currently, the tattoo for diabetics does not provide a numerical reading; however, scientists are working on developing a way to provide a numeric readout. They are also working on developing an application that is capable of sending information of diabetics in real time using Bluetooth technology.

According to the researchers, the tattoo could be used to measure other important chemicals such as lactate, a metabolite analyzed in athletes to monitor their fitness. This device may also be used to detect illegal drug or alcohol consumption, or to test how well medication is working.

Costing a few pennies and a less painful alternative for managing diabetes, this discreet and non-invasive device is a most welcome advancement for diabetics.

10 Powerful Ways to Stop Worrying and Start Living Today

10 Powerful Ways to Stop Worrying and Start Living Today

Plato knew that the body and mind are intimately linked. And in the late 1800s, the Mayo brothers, famous physicians, estimated that over half of all hospital beds are filled with people suffering from frustration, anxiety, worry and despair. Causes of worry are everywhere, in our relationships and our jobs, so it’s key we find ways to take charge of the stress.

In his classic book How to Stop Worrying and Start Living, Dale Carnegie offers tools to ditch excessive worrying that help you make a worry-free environment for your private and professional life.

These are the top 10 tips to grab worry by the horns and wrestle it to the ground:

1. Make Your Decision and Never Look Back

Have you ever made a decision in life only to second-guess it afterwards? Of course you have! It’s hard not to wonder whether you’ve done the right thing and whether there might still be time to take another path.

But keep this in mind: you’ve already made your decision, so act decisively on it and dismiss all your anxiety about it.

Don’t stop to hesitate, to reconsider, or to retrace your steps. Once you’ve chosen a course of action, stick to it and never waver.

2. Live for Today, Package Things up in “Day-Tight Compartments”

You know that feeling: tossing, turning and worrying over something that happened or something that might, well into the wee hours. To avoid this pointless worrying, you need “day-tight compartments”. Much as a ship has different watertight compartments, your own “day-tight” ones are a way to limit your attention to the present day.

The rule is simple: whatever happened in the past or might happen in the future must not intrude upon today. Everything else has to wait its turn for tomorrow’s box or stay stuck in the past.

3. Embrace the Worst-Case Scenario and Strategize to Offset It

If you’re worried about something, ask yourself: “What’s the worst thing that could happen?” Could you lose your job? Be jailed? Get killed?

Whatever the “worst” might be, it’s probably not so world-ending. You could probably even bounce back from it!

If, for example, you lose your job, you could always find another. Once you accept the worst-case scenario and get thinking about contingency plans, you’ll feel calmer.

4. Put a Lid on Your Worrying

Sometimes we stress endlessly about negative experiences when just walking away from them would serve us far better.

To make squashing that worry easier, try this strategy, straight from stock traders: it’s called the “stop-loss” order, where shares are bought at a certain price, and then their price development is observed. If things go badly and the share price hits a certain point, they are sold off immediately. This stops the loss from increasing further.

In the same manner, you can put a stop-loss order on things that cause you stress and grief.

5. Fake It ‘Til You Make It – Happiness, That Is

We can’t directly influence how we feel, but we can nudge ourselves to change through how we think and act.

If you’re feeling sad or low, slap a big grin on your face and whistle a chipper tune. You’ll find it impossible to be blue when acting cheerful. But you don’t necessarily need to act outwardly happy; you can simply think happier thoughts instead.

Marcus Aurelius summed it up aptly:

“Our life is what our thoughts make it.”

6. Give for the Joy of Giving

When we perform acts of kindness, we often do so with the expectation of gratitude. But harboring such expectations will probably leave you disappointed.

One person well aware of this fact was the lawyer Samuel Leibowitz. Over the course of his career, Leibowitz saved 78 people from going to the electric chair. Guess how many thanked him? None.

So stop expecting gratitude when you’re kind to someone. Instead, take joy from the act yourself.

7. Dump Envy – Enjoy Being Uniquely You

Your genes are completely unique. Even if someone had the same parents as you, the likelihood of someone identical to you being born is just one in 300,000 billion.

Despite this amazing fact, many of us long to be someone else, thinking the grass is greener on the other side of the fence. But living your life this way is pointless. Embrace your uniqueness and get comfortable with who you really are: How to Be True to Yourself and Live the Life You Want

8. Haters Will Hate — It Just Means You’re Doing It Right

When you’re criticized, it often means you’re accomplishing something noteworthy. In fact, let’s take it a step further and consider this: the more you’re criticized, the more influential and important a person you likely are.

So the next time somebody talks you down, don’t let it get to you. Take it as a compliment!

9. Chill Out! Learn to Rest Before You Get Tired

Scientists agree that emotions are the most common cause of fatigue. And it works the other way around, too: fatigue produces more worries and negative emotions.

It should be clear, therefore, that you’ve got to relax regularly before you feel tired. Otherwise, worries and fatigue will accumulate on top of each other.

It’s impossible to worry when you are relaxed, and regular rest helps you maintain your ability to work effectively.

10. Get Organized and Enjoy Your Work

There are few greater sources of misery in life than having to work, day in, day out, in a job you despise. It would make sense then that you shouldn’t pick a job you hate, or even just dislike doing.

But say you already have a job. How can you make it more enjoyable and worry-free? One way is to stay organized: a desk full of unanswered mails and memos is sure to breed worries.
