Scientists create working lab-grown rat kidney

There are a huge number of people all around the world that are currently very ill and in need of replacement organs. The problem is for some of these people, they will die before a donor organ is available. Scientists around the world are currently working to create alternative ways to get replacement organs for surgical procedures.

One of the methods scientists and researchers are investigating is the ability to grow living organs in a laboratory setting. Scientists in the United States have announced they have been able to successfully grow a rat kidney in the laboratory. The kidney was then transplanted into the rat where it began producing urine.

However, the lab grown kidney is reportedly less effective than a natural kidney. Growing a kidney in the lab is a huge deal because kidneys are the most in-demand organs for transplant and transplant lists for kidneys are some of the longest. The goal of the researchers involved in the project is to be able to take an old kidney and strip it of all the old cells leaving a honeycomb-like scaffolding. The kidney can then be rebuilt with cells taken from the patient.

The major benefit of growing kidney in this manner would be that the cells belong to the patient making rejection less likely. Having cells from the patient will also mean that recipients wouldn’t require immunosuppressive drugs to prevent rejection of the donated organ. Researchers involved in the project face significant challenges in applying this technique to growing human kidneys. The scientists say that the sheer size of the human kidney will be a challenge on its own. The larger an organ, the more difficult it is to get the cells into the correct location according to the researchers.

Sharp offers USB-powered ion generator air purifier

USB-powered gadgets tend to run the gamut from the mundane to the truly bizarre. We’ve seen plenty of USB-powered air purifiers over the years that aim to remove odors and pollutants from your room or office. We’ve also seen a number of USB devices and that remove pollen and other items from the air you breathe as well.

plasma-cluster

A new USB air purifier has turned up from Sharp called the Sharp IG-DK1A Humidified Plasmacluster Ion Generator. That is a long name for device that has a pretty simple function, this device is designed to humidify the air you breathe and create lots of ions. Negatively charged ions are used by a lot of air purifying devices to attract dirt particles and other tiny particles floating in the air.

Once those particles of dirt, pollen, and dander are attracted to these negative ions they clump together and then fall to the ground. The particles might not be physically filtered from the air you breathe, but my removing them from floating around in the air you’re much less likely to breathe them in. One of the biggest upsides to this sort of air purifying technology is that there are no filters to be replaced.

This particular air purifier is able to create quite a few negatively charged ions to the tune of 25,000 ions/cm3. The air purifier measures 124 mm x 182 mm x 166 mm and weighs 820 g. The device also has a small 300 mL water reservoir that consumes water at 30 mL an hour. That small reservoir is used to humidify the air. The internal fan of this device can also be powered using a normal AC adapter if you don’t want to plug in near your computer. The air purifier sells for $220.

Asthmapolis Wants To Hack The Inhaler And Help 26 Million Americans Better Track And Manage Their Asthma

Screen shot 2013-04-05 at 2.33.11 AM

Unless you’re reading this while using an inhaler, this fact may surprise you: According to the CDC, 26 million Americans currently have the chronic respiratory disease we know as asthma. Not only that, but the CDC tells us that the disease costs the U.S. $3,300 per person annually, and medical expenses associated with asthma have increased to about $56 billion (thanks to hospitalizations, emergency room visits and missed work), while over 10 percent of insured Americans are unable to afford their prescription medicines.

Asthmapolis launched in 2010 to help find a solution by leveraging the advances in sensor technology (and the reduced costs of producing said sensors) and mobile data monitoring to help people manage their asthma more effectively, in turn reducing the costs both for those suffering from asthma and for the U.S. healthcare system itself. And, today, the Wisconsin-based startup has announced that it has raised $5 million in Series A financing from The Social+Capital Partnership to build out a comprehensive solution and support system for those with the chronic respiratory disease.

Asthmapolis is one of a new generation of digital health startups attempting to hack the old software, devices and care systems that continue to prevail in today’s healthcare landscape. We recently wrote about Intersect ENT, for example, which is hacking stents (yes, stents) to help doctors more effectively treat the 31 million-plus people suffering from sinusitis.

Meanwhile, Glooko, Omada Health and a number of other startups are bringing mobile and digital technology to those with diabetes to help them manage the condition and, in Omada’s case, hopefully even prevent it.

Asthmapolis, on the other hand, is on a mission to hack your inhaler. The startup has designed snap-on, Bluetooth-enabled sensors that track how often people are using their inhalers (along with location and time-of-day), along with analytics and mobile apps for iOS and Android to help them visualize and understand their triggers and trends while receiving personalized feedback.

In turn, the data collected by the solution enables doctors to identify patients who are risk or need more help controlling its symptoms. This allows them to potentially prevent attacks before they happen, saving them the cost of hospitalization or a trip to the emergency room.

In fact, Asthmapolis’ early studies found that this access to realtime data was able to reduce the number of people with uncontrolled asthma (or those not regularly using inhalers) by 50 percent. Without realtime data and the ability to collect information on the context and situations in which people develop symptoms, doctors are groping around in the dark and waiting for attacks before they analyze context and begin treatment.

Many startups are beginning to recognize the opportunity both to create a sustainable businesses and affect real change by positioning themselves at the intersection of growing trends like mobile devices and mobile health initiatives, personalized medicine, big data and sensors. Asthmapolis co-founder and CEO David Van Sickle thinks that the startup can sit at that intersection, while differentiating from competitors by offering both a hardware and software solution.

Not only that, but Asthmapolis received approval from the FDA in July to market its asthma-tracking device and software solution to consumers, which puts it on a very short list. In turn, its software platform, which is available both in English and Spanish, allows users to keep a digital log on their use of medications, while receiving personalized feedback — both designed to improve their ability to successfully manage the disease.

In the big picture, the startup also wants to help public health institutions better evaluate the efficacy of their interventions and treatments and unlock insight into how asthma works and where it originates. And that’s where Asthmapolis is monetizing: By selling its hardware and software solution to payers and health plan providers. With more effective treatment solutions, insurance providers and health plans can save between $4,000 to $6,000 in annual healthcare costs — and, naturally, that’s money in the bank.

The company has formed a number of partnerships in the last year in this regard, which include programs with payers like Amerigroup Florida/WellPoint and providers like Wyckoff Heights Medical Center in New York and Dignity Health in California. Going forward, the startup will look to continue expanding its relationships with providers and payers, along with initiatives in retail pharmacy and the public sector.

“Asthmapolis is in a unique position in healthcare IT,” explains Social+Capital General Partner Ted Maidenberg, “where its technology can easily integrate with existing behaviors (like using your inhaler), while adding a huge amount of data (time, location, activity) that provides a much smarter package compared to your over-the-counter inhaler.”

DuoFertility Is A Fertility Monitoring Sensor-Plus-Service That Helps Childless Couples Get Pregnant

DuoFertility Colours 2

UK startup DuoFertility is tackling a really tough problem: infertility. The company has built a sensor-plus-service business to predict the most fertile days of women who are having difficulty conceiving to improve the chances of conception — hence its tagline: “assisted natural conception”. There is no invasive technology involved, just a lot of number crunching.

The startup’s approach sits somewhere in the middle of the competition in this space. It argues its technology is more sophisticated than more basic over-the-counter physical products such as home urine tests or body-basal-thermometers (which are also cheaper than DuoFertility’s offering), as the data captured by its wearable sensor is more accurate. Data is also sent back to DuoFertility staff for monitoring and reviewing – so it’s being looked at by specialist staff using bespoke algorithms rather than generalised models.

On the other hand, the product is cheaper than a cycle of artificial insemination — and much cheaper than IVF. It’s also nowhere near as invasive as either of those alternatives. DuoFertility costs £495 with unlimited support vs around £800 for a cycle of artificial insemination (including drugs and tests) and around £4,5000 for a cycle of IVF, says CEO and co-founder Shamus Husheer.

“It is this combination of both automated analysis and expert review of this data that sets us apart from anything else out there, and probably to a large extent explains why our pregnancy rates are so high for patients who are well past buying something off the shelf at the pharmacy,” he says

“The really surprising thing is that, for only a relatively small increment in cost over the [more basic, competitor] at-home devices, DuoFertility gives a vastly higher pregnancy rate than artificial insemination, and even matches or exceeds that of IVF.”

Success is a little difficult to measure, however, as a variety of factors have to be considered – as Husheer explains: “Although 80% of normally fertile women will get pregnant within their first year of trying to conceive, infertile couples (those who have been trying for more than two years) have only about a 12% chance of getting pregnant over a year. Therefore simply saying x% of patients will get pregnant is meaningless (or worse, misleading) – this does not however prevent some less scrupulous clinics and products from doing exactly this.

“Therefore we publish our success rate data only on these ‘difficult cases’ of infertile patients, and specifically those who have qualified for or already been through IVF. We then break this data down by both female age and time trying for a baby, which are the most important factors in determining success rate. A peer-reviewed scientific paper on exactly this was published at the end of 2011, demonstrating a pregnancy rate that was higher than that from a cycle of IVF for every age group under 45 (the rates themselves ranging from over 40% to less than 15%).”

The Technology

So what exactly does DuoFertility’s technology do? The product consists of a wearable sensor, worn inside an adhesive patch so it remains attached day and night, which logs the woman’s “body temperature and movement thousands of times a day and night to calculate deep sleep core temperature”, plus a reader unit which receives the data from the sensor via a modified version of RFID. The reader calculates likely future fertility — based on “all of the information it has seen about you to date” (users can enter “a range of different parameters on the reader, from menstruation to ovulation pain to illness”).

The reader connects to a PC via USB to display past and near future fertility charts. Additional data can then be added by the user, such as medical or home test results and notes for DuoFertility’s staff to read. And all the data is automatically transferred to DuoFertility’s servers in Cambridge, U.K. for analysis and expert review.

“We use all of the data for each individual woman, and all of the thousands of others that we’re monitoring, to work out exactly which algorithms work for the woman most similar to this one,” says Husheer. “That allows us to dramatically improve the prediction of fertility, but also allows us to identify a range of underlying issues that may be preventing conception. There are of course many cases where the data does not perfectly fit any existing model, and so these cases are escalated to human fertility experts for review and, if necessary, a discussion with the patient or their doctor.”

DuoFertility aims to identify the 42-78 hour monthly window when couples should be trying to conceive — and says that by continually monitoring women it can pick up on signs that a particular cycle is similar or different to a previous cycle, as well as compare a cycle to similar cycles in its database.

“Basically, there is zero point in providing a prediction of ovulation down to the minute, if in fact it is five days wrong. Far better to give couples a realistic assessment of when they are likely to be fertile, and update this as we get more data. This means that for some couples ‘the goalposts move’ – they can quite literally see our algorithms updating the prediction when they connect to our servers. And if we recalculate something at our server, and they haven’t connected recently so might miss the newly calculated critical moment – we send an email or give them a call. That call has resulted in more than one baby,” adds Husheer.

Of course not every couple will be able to get pregnant — even after using the product for a long time — so customer relationship management is a “pretty critical” component of the business. Raising false hope is certainly not part of DuoFertility’s business model, says Husheer — although he notes that for couples who can’t afford IVF, continuing to use DuoFertility despite poor “absolute chances” may be their best hope. ”We find that being absolutely crystal clear about this often makes for a difficult but ultimately necessary and productive conversation with the couple,” he says. The startup also offers refunds to new users if it believes it won’t be able to help them, and reviews users after four to five months (and regularly after that) to ensure continued use still makes sense for them.

Starting up

The idea for Duofertility was conceived during Husheer’s PhD research at Cambridge University. The link is indirect, since his research was actually building instruments for particle accelerators. “I realised that several of the instrumental techniques we used could be applied to human physiology, and specifically to monitoring fertility,” he tells TechCrunch. 

Husheer (pictured right, with fellow co-founder Oriane Chausiaux) and a group of fellow graduate students – “scientists and medics”, some with PhDs in infertility – then got together and entered a university business plan competition in 2006, going on to win £20,000. The money funded a prototype and the filing of the first patent. “By mid 2007 we had brilliant data and several local Angel investors telling us to hurry up and graduate so that they could fund the project,” says Husheer. “Just 18 months and less than £1 million later, DuoFertility had been through design, development, trials, medical approvals and sold to the first customer.”

The first DuoFertility was bought in May 2009, although Husheer says the first pregnancy was “actually somewhat before that” — during early trials. “Sales really stepped up when DuoFertility was stocked by the largest UK pharmacy chain, Boots, in 2011 as the result of our participating in a reality-TV show hunting for innovative new products for the major retailers,” he adds.

Further funding came via the competition route, after DuoFertility won Qualcomm’s European QPrize in 2011. That in turn led to attention from Qualcomm’s venture capital arm. Husheer says the company has now raised a little over £2 million in funding from three Angel investor groups and from Qualcomm Ventures.

Growing In The U.S.

DuoFertility’s next big step will be raising its profile in the U.S. — by targeting key national medical conferences such as the American Congress of Obstetricians and Gynaecologists in May, and the American Society for Reproductive Medicine in October to properly enter the market. Husheer notes the company “recently achieved FDA clearance”, and although U.S. users can buy the device via DuoFertility’s website and be supported in using it, he says the business needs to spend time introducing the product to the medical community to make doctors aware of it and ensure they are happy to recommend it.

“We have a small team on the ground in the U.S., calling on doctors in New York and California to introduce the product and make sure that DuoFertility fits into the way that they practice medicine. Over the next few months we will be hiring several more commercially focused people, both for activities directed at the medical community and the consumer — so any [TechCrunch] readers with experience in bringing similar technologies to market in the US should drop me a line,” says Husheer.

“From a regulatory perspective we are clear to sell anywhere in the E.U. or U.S., and in several countries that accept their medical clearances (e.g. South Africa and many Arab states). As a company selling on the Internet it will be no surprise that we have patients in almost all of these places – in fact we now have babies on every continent except Antarctica. That said, our primary focus is the U.K. and U.S.,” he adds.

Part of the issue with the U.S. market is that, for legal reasons, DuoFertility is not allowed to provide medical advice to the patient directly — but must work through the patient’s doctor. “This means their doctor is preferably included ‘in the loop’ from the beginning, however if the patient just uses DuoFertility without a doctor we can refer to a doctor we work with in their city if they need one,” Husheer adds.

DuoFertility has more than 30 staff at present, working shifts to ensure U.S. timezones are covered. The number of staff is likely to rise over the next year — especially if the company  replicates its U.K. fertility centre on U.S. soil so that American couples can be monitored by staff in the same timezone.

The company broke even in 2011 but has been ploughing investment into ramping up for the U.S. market so, overall, the business has not been profitable recently but Husheer says that’s all part of its growth plans: “Our investors seem to be very happy with this strategy, as everyone can see that the US will be the major market for us.”
