Apple announced at its recent WorldWide Developers Conference in California that it would soon be offering users the chance to monitor their glucose levels. The company has partnered with medical device maker Dexcom and will link the company’s glucose monitoring device with the Apple Watch.
For some time now, Apple has been positioning itself as a dedicated health and fitness provider through the Apple Watch series. However, while Apple has previously marketed itself towards lifestyle and fitness fanatics, it has yet to enter the medical device sector.
Apple has also previously been reported to be hiring a small team of biomechanical engineers to develop sensors that monitor the body’s blood sugar levels. The team are said to be working on non-invasive sensors that do no require users to prick their skin for blood testing.
Apple is also now home to our new OTC DASHBOARD app. To download it from the Apple Store now, click here.
VTT TecVTT Technical Research Centre of Finland has developed a wearable assistive device for the visually impaired, which enables them to sense their environment and move around more safely. The device, which is worn like a heart rate monitor, has been clinically tested.
The device functions on the basis of a radar system developed by VTT. The radar sends information to the user in the form of vibrations or voice feedback. It senses a majority of obstacles in the user’s surroundings, however difficulties do however remain in sensing objects such as thin branches and bushes.
“The novel aspect lies in a wearable sensor device which functions based on radio waves, so the signal is able to pass through clothing. This means that it can be worn discreetly under a coat, for example,” says Tero Kiuru, a Senior Scientist at VTT.
The radar has already been clinically tested in device trials approved by the National Supervisory Authority for Welfare and Health (Valvira), in which VTT’s partners were Kuopio University Hospital and the Finnish Federation of the Visually Impaired (FFVI). The test group included a total of 25 visually impaired people, of whom 14 were blind, 7 partially sighted and 4 were deaf-blind.
“A clear majority of the testers felt that the radar improved their ability to perceive their environment and increased their self-confidence when moving around,” says Kiuru. A total of 92% of the trial users felt that the device helped them to perceive their surroundings, 80% felt that their trust in their ability to move around independently had increased and 32% would immediately start using the test device in its current form.
On the other hand, they were not satisfied with distance control and vibration-based feedback. The research will continue with selected test users and the device will be further developed. A global market is believed to exist for the radar, since there are around 300 million visually impaired people in the world.
A new soft, flexible microfluidic device sticks on forearm or back skin to measure sweat and show how the body is responding to exercise. The small, simple, low cost device analyses key biomarkers to help a person decide quickly if any adjustments, such as drinking more water or replenishing electrolytes, is needed, or if something is medically wrong.
It is designed for one-time use of a few hours and features a number of innovations including:
• The ability to capture, store and analyse sweat in situ and in real time
• Can quantitatively determine biomarker levels using colorimetric analysis
• A power source is not required to display the results; instead, a smartphone camera and app are used to read the biomarker change
The device’s sensitivity even enables it to pick up the biomarker for cystic fibrosis and it is hoped that in future it may be used more broadly for disease diagnosis.
Study leader John A. Rogers, professor of materials science and engineering, discussed the device: “The intimate skin interface created by this wearable, skin-like microfluidic system enables new measurement capabilities not possible with the kinds of absorbent pads and sponges currently used in sweat collection.”
The team have studied the efficacy of the device in two groups of cyclists and found it to be both accurate compared to conventional lab analysis and durable in unpredictable environmental conditions. Their findings were published on 23rd November in Science Translational Medicine.
In its fourth year, and the second time hepatitis testing has been included, European HIV Testing Week is currently in action. Starting on 18th November, and finishing a week later, testing week is spanning the length and breadth of the continent with partners participating from over 50 European countries.
Prior to this, the world’s fastest HIV self-test kit went on sale last week in order to relieve pressure on overcrowded sexual health clinics.
bioLytical Laboratories, renowned for their production of rapid infectious disease tests, has developed the INSTI HIV Self Test, following research revealing that over 103,000 people are living with HIV in the UK and an estimated 18,100 remain unaware of their positive status.
It was reported recently that funding cuts have resulted in clinic closures across the country meaning the pressure is on for remaining clinics. Failure to fund routine testing in GP surgeries is leading to late diagnosis when early treatment of the disease is highly beneficial.
With one prick to a finger and a droplet of blood, the INSTI HIV Self Test provides immediate results and is over 99% accurate. Other home testing kits can take up to 20 minutes to produce a result, and in some cases laboratory test results can take several days or weeks.
The INSTI HIV Self Test kit also includes a resource card on where to seek help or for those who have general questions on HIV screening.
The test is available now online at www.INSTI-HIVSelfTest.com and costs €29.95 (£25.95) per kit.
Scientists in Singapore have developed a kit that can test for the Dengue, Chikungunya and Zika viruses all at the same time in just two hours.
The three mosquito-borne viruses cause similar symptoms such as rashes and joint pain. Symptoms for the Zika virus are generally mild and go away within a week, causing the disease to be misdiagnosed.
The kit is ready for use and only costs a few dollars to produce. Dr Masafumi Inoue, a senior research scientist at the Agency for Science, Technology & Research’s Experimental Therapeutics Centre confirmed that the World Health Organisation (WHO) has expressed interest.
Dr Masafumi Inoue is currently compiling clinical data for the health authority before sending the kit over for testing. If the testing is successful, the WHO may use the kit to test for the viruses.
As it is extremely important to quickly distinguish between the three major mosquito-borne viruses, the kit could prove incredibly useful in ensuring patients receive the required treatment and care without delay.
All that is required from the patient is a blood or urine sample. The genetic material of the virus is then extracted to find out what the virus is. The detection process takes two hours, reducing the time by threefold if each of the viruses were to be tested for individually.
The idea to develop the kit came about six months ago when Brazil had been hit badly by a large number of Zika cases.
This week’s OTC in Action episode brings back memories of caring for sick babies – agonising over whether to wake them for a temperature reading after a long night of tears, rocking, walking and calls to the paediatrician in the early hours of the morning. It also reminded me of the role temperature plays throughout those early years – the bottle, the bath, etc.
Recently, a panel of healthcare product buyers were likely remembering similar experiences when they voted Tecnimed Family First’s VisioFocus Smart as the Best Product finalist at the ECRM / Drug Store News’ healthcare trade show.
VisioFocus, from Italian company Tecnimed, is able to read temperatures by being pointed at foreheads, bottles and baths – and projecting the temperature on the baby’s skin or object surface. According to the company, in addition to being more hygienic because it does not touch the skin, it does not disturb a child’s sleep.
The temperature reading is also stored in the thermometer’s memory; such a valuable tool when tracking recovery. Its functionality for measuring liquid temperature will also add an extra safety net for nervous new parents.
Now, if only they could develop a device that would project teenagers’ mood swings…
Two areas we focus on in our latest OTC.NewDirections bulletin are new regulations for dietary supplements and medical devices. In Canada, quality assurance measures are being introduced for Natural Health Products, while across the border in the US, the FDA has issued guidance to help marketers distinguish between liquid dietary supplements and beverages.
