Today, researchers at Baylor announced that they have developed a sensory method that uses a circuit board small enough so that the device is portable.

To measure glucose levels, users must press a part of your hand or finger on the sensor. The Baylor investigadors daily samples of 31 people during the course of several months and compared these samples to levels measured by a commercially available sensor without a prescription. The researchers found that non-invasive sensor Baylor has the potential to achieve the same and even better accuracy than current commercial sensors, many of which require you to prick the finger to sample blood.

“For diabetics, the daily routine of pricking your finger to check levels of blood sugar can be an annoying and inconvenient task, but now we have a device that could potentially change that.” said Dr. Randall Jean, associate professor of computer and electronic engineering at Baylor. “We have the equipment to the point where it justifies a significant investment. The probability of success is very high.”

The sensor uses electromagnetic waves to measure glucose levels in the body. As the energy passes through the skin sensor and back to the sensor, the glucose level is measured by the energy transfer. Jean said that the microwave frequency range is wide enough to isolate the effect of sugar in the body and minimize the capabilities of other things like body fat and bone, which could alter readings. Jean also said that using electromagnetic waves is relatively safe because they do not ionize the molecules of the body as do X-rays.

Jean, who is pre-diabetic, has the patent for the general measurement method called pulse dispersion spectrometry ultra-broadband, and Baylor has applied for a provisional patent in regard to non-invasive monitoring of glucose. Researchers at Baylor now hope to conduct more tests on a larger diabetic population. The current commercial sensors measure the levels of glucose in the range of 20 to 600 milligrams per deciliter, while Baylor prototype sensor has been shown to have a range of 60 to 185 milligrams per deciliter, but Jean said the fact that the sensor has good resolution and accuracy over the limited range demonstrates that the technology can work.

This device would still be in the process of creation, a project that not only has the support of the European Community but also with 7.1 million directly financed by the Community institution.

As anticipated, the basis of DIAdvisor be a small wireless sensors, chip surrounded by a low Sicily, to be pasted into the body of patients and allow more data record: in addition to blood glucose, may also determine the body temperature, blood pressure and oxygen levels.

The same system will then transmit the data to the portable mobile device, which looks like a PDA or PDA.

But also we obtained this information, the device also will allow the patient to go beyond your control and up, for example, information about food that is consumed each day.

According to their own architects have emphasized, the most innovative of this device is to let you know how much insulin is needed: Keith Errey, co-founder of the project and president of Toumaz (manufacturer), highlighted the new opportunities offered to patients who so far have no ways to predict the levels of glucose and insulin they need.

It is worth mentioning, finally, that for the go live DIAdvisor still have to wait. According to estimates, within two years could just start clinical trials in real time with volunteers.

By developing the technology of ultrasound, microwave, laser and infrared light has succeeded in developing a wide range of medical devices that act through electromagnetic waves, sonic or physical. Most important is that these devices are available to any user, and you can get a good home oximeter for a small investment of 100 or 200, although some houses have as Quirumed cheaper models by just over 60 euros plus shipping shipment. In hospitals are classified as having a fixed oximeter plethysmographic curve but for private use or educational enough portable pulse oximeter, hand or finger. Nonin is one of the brands that specialize in pulse, you indicate both the oxygen values as the number of heartbeats per minute.

The normal values of oxygen in blood vary between 95% and 97% SaO2 so easily detected irregularities to be decreases below 95% saturation of O2. Go2 Nonin finger pulse oximeter is cheaper brand, you can buy for $ 99 in a few days pmedicalonline.net and start making the first tests with your own finger. It is designed to be used with fingers of size from millimeters to a centimeter and has 2 year warranty. Among the additions, plus a charger Go2 also have some support for adequate transportation, avoid losses and protect against falls, such as a bag, a briefcase and a simple string. There are several other notebook models Nonin 9500 Onyx from $ 200, and handheld pulse oximeters from $ 400 to $ 600 as the Nonin 2500 PalmSAT.

The main functions of this is patient care and monitoring the level of oxygen in cases of asthma there may be respiratory distress, cyanosis, control of oxygen therapy and the assessment of exercise tolerance. So that according to these functions can perform tests to see how exercise or changes in breathing may alter the level of oxygen in blood. You can also perform other experiences related to research projects specific to the Baccalaureate, to correlate the age with the amount of oxygen in the blood, or measure differences in this value between men and women.

In clinical practice are complementary to the gases, and are widely used in pediatrics to be the least invasive and most friendly to children. So a little ingenuity can be placed permanently if necessary, and notify you of any decrease in blood oxygen saturation. The main disadvantage of these devices is that regard, a gas analysis provides less information: do not measure the concentration of carbon dioxide, or the blood pH, and also for oxygen values are accurate only above 80-90%, so that are not useful for certain pathologies. As advantages we should mention its use simple and fast, in addition to its noninvasive application already discussed earlier.

Eduardo Pereira Hospital in Valparaiso was conducted technical training for CTH CHILE who will be responsible, effective March, perform security operations that medical equipment will be analyzed with high technology for check compliance with optimal conditions for use.

During the training sessions examined the characteristics of electrosurgical equipment analyzers, defibrillator, ventilator, patient simulator Electromedical safety. The training had a theoretical component where it was explained in detail the theories involved. Besides the practical activities for which the Hospital Eduardo Pereira provided some of their equipment.

The experience was very satisfying for the audience. The technical Tonolli Stephanie, who serves on the Barros Luco Hospital said: “Win acquire the basic knowledge to manage these teams. The way it was explained quite clearly and accurately. Within the teams watched my attention analyzer monitor (patient simulator) and also the defibrillator, due to easy access to select the various tests. In turn Jorge Torrejón, CHILE CTH technician also said: “The purchase of such equipment and related training measurement seem very consistent with the needs and objectives of the Technology Management to develop, it allows us to monitor and deliver a particular service to our partners, whose results can yield interesting clues as to the Electromedical Security are working in hospitals today.

The activity marks the start of the delivery of this new service will begin to implement CHILE CTH in the different partner institutions and which falls within one of the goals of the project: to advise on security issues, ensuring optimal conditions for both teams users and patients.

With these data, patients may tune in the administration of doses, avoiding physiological complications arising from an excess of insulin. In four years it is expected that the technology is available on the market. Scientists say it is very necessary because diabetes is increasingly present in our society as a result of lifestyle we lead. For Yaiza Martínez.

Diabetics can reduce the amount of insulin that administrate with the help of a new portable and wireless device designed to predict blood glucose levels.

This device, known as “DIAdvisor ™” will be developed by the company Toumaz Technology, specializes in manufacturing wireless devices and low power consumption to control the body. The project falls under the Seventh Framework Program of the European Community, which has earmarked 7.1 million euros.

The purpose of development of this device is to improve the lives of millions of diabetes patients, with an art tool for personalized prediction of blood glucose levels, reports Toumaz Technology in a statement.

The tool will be created thanks to a partnership of 13 doctors and several industry partners and academics. The work will be coordinated by Novo Nordisk company specializing in the care of this disease.

What is

DIAdvisor technology (Personal Glucose Predictive Diabetes Advisor) will be based on a wireless control technology of the body, existing and belonging to the company Toumaz Technology Sensium call.

Sensors consist of small, wireless and discreet, surrounded by a silicium chip low-power, which will stick to the body of the sick to log certain data, such as body temperature, blood pressure, blood glucose levels or oxygen, among other parameters.

According to The Engineer magazine reported online, the system transmits this data to a portable mobile device like a PDA or PDA. By hand, it may also introduce any other information you want, like food that has consumed the patient.

All these data will be analyzed later by an advanced algorithm to determine glucose levels in the patient’s blood at any particular time. In this way, patients will know in a matter of minutes, the amount of insulin will be administered at the next dose.

Breakthrough
According to Keith Errey, co-founder and president of Project Toumaz, current techniques for managing diabetes does not offer the ability to predict blood glucose levels in the short term. This means that patients should almost assume the amount of insulin they need to recover the stable levels of blood glucose.

Scientists hope, moreover, that this technology serves to avoid the risk of blackouts suffered by diabetics when their blood sugar levels drop dramatically. Many of the sick, in fact, prefer to consume higher doses of insulin than necessary to avoid the crisis, but the excess insulin also has its risks, including possible damage to the eyes, heart or liver.

But before he can see the light DIAdvisor are still important steps to take, how to define the combination of vital signs that provide the best information to determine the blood glucose level. For this, scientists will have a team of volunteers with diabetes to help generate the physiological models and prediction algorithms.

Within two years, will begin clinical trials in which they will operate these algorithms in real time and test the prediction models. If everything runs according to plan for the scientists, the technology will be available in the market within four years.

Technology increasingly necessary
According to published Toumaz, the massive increase in the incidence of diabetes is now a major global health challenges. This increase is due to demographic trends clear, as the epidemic of obesity, aging, or the spread of sedentary lifestyles.

All these factors have caused a massive spread of diabetes, especially type 2. In the case of type 1 diabetes, the pancreas does not produce insulin, but in the pancreas of type 2 if that makes it, but the body assimilates as it should.

Consequently, the pancreas produces more insulin to get glucose into cells, and just exhausted due to excessive strain. In addition, blood sugar levels get too high.

In the European Union, the average prevalence of this disease is 7.5% but is expected to increase to 16% in 2025. Scientists hope that, with DIAdvisor, it can provide a sophisticated treatment of the sick, thus enhancing self-management of disease and reduce the risk of serious complications resulting from poor control of glucose levels in the blood.

Stergiou of Sotiria Hospital of Athens (Greece) and colleagues assessed the automatic device in 73 people: 27 with atrial fibrillation, 23 with arrhythmia other than atrial fibrillation and 23 reference persons in sinus rhythm.

Overall, rose to 217 blood pressure measurements, all with simultaneous ECG monitoring.

The authors note that when the diagnosis of atrial fibrillation was based in a single measurement, the sensitivity of the algorithm was 93% and specificity of 89%.

Under optimal circumstances (three measurements with at least two to diagnose atrial fibrillation) the sensitivity was 100% and specificity of 89%, indicating a “near perfect match” with the electrocardiograph diagnosis.

Under these optimal circumstances (diagnosis based on two measurements at least three positive) diagnosis of atrial fibrillation was incorrect in five people.

In all these cases, patients had arrhythmia other than atrial fibrillation in the three measurements.

Dr. Stergiou told Reuters Health that long-term self-monitoring of hypertensive patients using a device equipped with an atrial fibrillation detector would allow an earlier diagnosis without additional screening costs.

He added that the “implementation of this technology should be evaluated in other devices for measuring blood pressure and for ambulatory blood pressure monitoring 24-hour blood pressure (especially in patients with intermittent atrial fibrillation), which could also contribute to Early detection of undiagnosed atrial fibrillation and therefore the prevention of stroke. ”

“Additional research is needed on the accuracy of electronic blood pressure monitors in patients with atrial fibrillation, aimed at improving the treatment of hypertension in these patients.”

However, these machines are usually quite large, and the most modern “portable” is the size of a printer.

For now the GE (General Electric) has demonstrated a truly portable ultrasound system the size of a cell phone, which he calls the vscan GE Ultrasound System.

In this first generation, the device can operate for up to 1 h duration with a battery (exchangeable) integrated, and microSD cards can store images and videos, which can later be downloaded to PCs and traditional computers can even burn notes voice separately.

The standard equipment is configured for HP, OBGYN, and Abd (terms such equipment operators understand) and color Doppler support across the screen, which step can be manipulated with your fingers to issue commands and make JOINING zoom like an iPhone.

The device will be available next year at U.S. $ 10,000, and it is currently being tested in some health centers.

It is important to note that these teams started costing millions of dollars and being the size of an entire room, after hundreds of thousands of dollars, and now cost $ 10,000 and fit in the palm of the hand. A great testament to the exponential growth of technology, which incidentally causes a reduction in costs exponentially.

In the future I imagine that these devices do not use screens, but images deployed directly onto the retina of the operator with technologies like this.

This technique is like providing a “big picture” to facilitate the genetic study of the AIDS virus. Not only led to the discovery of AIDS therapies in new ways, this technique can also be used to observe and diseases such as influenza virus and others.

“We really hope that this technique can help find the most potent drugs,” said Kevin Weeks of the University of North Carolina, as quoted by Reuters.

“We’ve had a series of major plans we can try through this technique,” he added.

According to Weeks, there are many structures contained in the RNA of HIV genetic role in the expression of the genetic code. Formerly, the role of this structure is not considered to have an important role.

Weeks and his team then developed a new chemical method called SHAPE to create an image of RNA nucleotides and also its shape and fold the edge of the RNA.

Other imaging methods such as X-ray Crystallography can capture the position of each atom exactly, but only in small areas. While SHAPE, showed greater imaging, but not at the atomic level.

“In essence, this technique such a way that enlarge image imaging genetic mapping to get a broader view and more complete details on the genetic virus,” said Weeks.

This technique will help researchers create drugs that is more effective to treat a variety of viruses from the disease.

New drugs will be produced to meet the specific requirements of the virus structure, so it can block them to attack the cells or at least prevent it can replicate itself.

Traditional treatment requires the use of amblyopia special glasses so thick that for several months before the eyes of patients actually improved.

According to the researchers, this method will actually worsen the conditions that resulted in eye health social stigma for the patient’s infancy. In other words, this method is not 100 percent effective. Such information is quoted from the Times of India.

Ophthalmologist and a brain Uri Polat, from Tel Aviv University developed a computer method of therapy that helps heal children with amblyopia by allowing them to enjoy the fun playing games while undergoing therapy.

When patients late in playing computer games, he would stay awake and hopes things beyond expectations.

“How this treatment, originally only intended for adults only, namely to improve nerve activity in the brain, which acts as the operator function of the eye. But when applied to children with amblyopia, the therapy seems to play this game can also heal them,” Polat said.

The results showed that the therapy was in front of the computer for 20 hours of therapy has an effect equivalent to 500 hours using special glasses amblyopia patients.

Polat was now working with gaming experts from the University of Rochester developed a special game for therapy children with amblyopia.
