cki web heart device 02 CardioKinetix Receives Expanded CE Approval for Parachute Percutaneous Left Ventricular Partitioning DeviceCardioKinetix has developed a novel transcatheter implant called Parachute Ventricular Partitioning Device, which already received the CE mark and has now won approval for two additional sizes. The Parachute is a partitioning membrane deployed within the compromised ventricle that is intended to treat heart failure resulting from myocardial infarction.

parachute CardioKinetix Receives Expanded CE Approval for Parachute Percutaneous Left Ventricular Partitioning DeviceThe Parachute consists of a synthetic fluoropolymer (ePTFE) membrane stretched over a nitinol frame. The idea behind the device is that it partitions the damaged muscle, isolating the non-functional muscle segment from the functional segment, which decreases the overall volume and restores a more normal geometry and function in the left ventricle.

Early trials have shown the Parachute to decrease heart failure symptoms and increase exercise capacity and quality of life, with additional trials underway. If indeed proven effective, this could be an important addition to the interventional cardiologist’s toolbox.

vinjuqby Ultrasound Treatment Shows Potential as Male Contraceptive TherapyResearchers from the University of North Carolina, School of Medicine have successfully tested ultrasound treatment to reduce sperm counts in rats to levels that would cause infertility in men. They used commercially available therapeutic ultrasound equipment, with which they tested the effects of different frequencies, temperatures and duration of ultrasound treatment on the sperm count. The results are published in the journal Reproductive Biology and Endocrinology.

The first report of the effect of ultrasound on germ cells and fertility was produced back in the seventies, by Mostafa Fahim and colleagues at the University of Missouri at Columbia. The aim of the current study was to determine the effect of currently available ultrasound equipment and if this technology could be used as the basis for a male contraceptive in the future. Their findings show an optimal result with two consecutive ultrasound treatments at 3 MHz, 2.2 Watt per square centimeter, for a duration 15 minutes, at a temperature of 37 degrees Celsius when the sperm count in the rat model dropped to a level that would cause infertility in men.

Advantages of ultrasound are the non-invasive nature of the treatment and its efficacy. However, at this moment not much is know of the long-term therapeutic prospects and side-effects of this treatment. In any case, this research has presented ultrasound as a potential basis for male contraceptive in the future and we will have to wait on the results of research to confirm this. And to guard your male fertility in the meantime, make sure your groin stays clear of ultrasound transducers.

stead burwell Digital CPR: E Patient to E PatientStead Burwell is a Chief Executive Officer of Alliance Health Networks. Since 2006, Mr. Burwell has been working with Alliance Health to help its founder, Geoff Swindle, build and strategically grow its business. Mr. Burwell has worked with startups in several different capacities as an operating executive, founder, venture board member and angel investor.

When Lana Barhum awoke one day unable to walk or use her hands, she knew something was wrong.

Later, when she received diagnoses of rheumatoid arthritis and fibromyalgia, conditions that in many ways still puzzle doctors, she turned to the Internet for more information and began blogging her tips for how to live successfully despite the pain. She also joined Arthritis Connect, an online social network, where she could learn from and share information with others with arthritis.

“Arthritis can be a lonely condition and support is an essential part of living despite our limitations,” said Barhum, now an advocate and mentor on the site. “The best people to connect with are those who understand your everyday struggles.”

The Internet provides people like Lana access to health information and specialists. But increasingly it has also opened up a space for connecting with others who share similar conditions, through blogging and social networking.

The Pew Research Center recently found that one in five Americans have gone online to find people with similar health concerns. For people with chronic illnesses, it’s one in four. Not surprisingly, doctors remain the first choice for an accurate medical diagnosis. But with more than 46 percent of patients saying they turn to their friends, family and other patients for day-to-day advice, social networking is clearly filling a need.

Studies show online support groups foster positive health outcomes, including escalating good, healthy habits. People are much more likely to achieve their health goals when paired-up with others who have similar goals. Healthy habits, such as eating right, sharing best practices and exercising, can truly go viral if the proper networks are established for the right information to be passed on.

Case in point: The Center for Connected Health released a study showing how social networks benefited patients with psoriasis, a common skin condition that causes skin redness and irritation. Nearly half of the participants reported an improvement in their quality of life after joining the online support site and 40 percent reported improvement with the severity of their psoriasis.

Social networking has created an outlet for patients and caregivers to put aside their reservations and ask important questions they probably wouldn’t ask in person. Social networks enable patients to open up and empower themselves to cope with their conditions through mutual support, ultimately leading to better lives.

Not all social networks are created equal

Not every social network is an appropriate venue for patient networking. The very nature of popular networks such as Facebook and Twitter provide a public stage to share personal information. However, patients may be (and should be) wary about sharing very sensitive and personal information on such sites. Although people can find emotional support on mainstream social networks, they can unintentionally invite unnecessary comments. A large, public forum means patients are less likely to post important or personal health questions.

At Alliance Health Networks, we aim to empower patients by making it easy to start conversations with other patients in the same situation. With more than 50 disease-specific social networks, like Arthritis Connect where Barhum participates, Alliance Health offers a variety of features that allow members to explore health and wellness topics on their own terms, share treatment experiences and post product recommendations. The resulting support and camaraderie help empower community members living with a chronic illness, and ideally improves their quality of life.

We have partnered with Tufts University School of Medicine to examine how utilization of disease-specific online social networks differs by condition, including levels of member engagement, attitudes toward using technologies for disease management and the value of online social support. We’re excited to see the results of the study and determine how members on our various social networks engage with one another so we can better tailor our communities to fit their needs.

Health care providers joining the online conversation

Recognizing that online communities are becoming more popular and rapidly growing, many of the largest and most respected health organizations and institutions are looking for ways to engage patients online.

Mayo Clinic, a leading nonprofit organization in medical care, research and education, is a trailblazer in this space. With nearly 300,000 followers on Twitter and close to 70,000 connections on Facebook, the organization recognized a growing need to provide an outlet for patients to engage one another. In July 2011, Mayo Clinic launched a social network for current and prospective patients, which now has some 13,000 registered users and continues to grow. This network allows patients to talk about their conditions, share their experience at the Mayo Clinic, post questions and provide encouragement to other patients exploring treatment options.

Joslin Diabetes Center, the world’s leading diabetes research and clinical care organization, recently started actively participating on Alliance Health Networks’ Diabetic Connect (www.diabeticconnect.com), the largest online community focused specifically on diabetes. Diabetic Connect’s 670,000 members have direct access to Joslin medical experts, including diabetes educators, endocrinologists and clinicians, and can follow blog posts, ask the expert questions and track other topics of interest. Additionally, we are working together to develop other diabetes management tools, including interactive online classes. The first of the series will be “Monitoring Matters,” consisting of interactive tutorials that will be hosted on the Diabetic Connect and Joslin website.

The future of connected health

It’s easy to see the movement of health services transferring online. As empowered patients continue to scour the Internet for information and look for ways to connect with peers managing similar conditions, the role of tailored, private social networks will become increasingly relevant. People have always come together to share health-related support and advice – now, they can do it at Internet speed and scale.

silk worm scaffold Silkworm Cocoons Proving Effective as Cardiac ScaffoldsCardiac cell death is an irreversible consequence of a myocardial infarction, often resulting in a chronically reduced cardiac output and symptoms of CHF.  German researchers from Max Planck Institute for Heart and Lung Research in Bad Nauheim have been working with Indian scientists to create a scaffold within which cardiac cells can be safely populated and then used as patches for damaged hearts.

They discovered that silk protein fibroin from Antheraea mylitta, a tasar silkworm found in India, can be an excellent material to support lab grown cardiac cells.  So far the team has been working with rat heart cells, and though the research is promising they don’t see a clear path to clinical studies due to the difficulty of gathering patients’ own cardiac cells.

“Whether natural or artificial in origin, all of the tested fibres had serious disadvantages,” says Felix Engel, Research Group Leader at the Max Planck Institute for Heart and Lung Research in Bad Nauheim. “They were either too brittle, were attacked by the immune system or did not enable the heart muscle cells to adhere correctly to the fibres.” However, the scientists have now found a possible solution in Kharagpur, India.

At the university there, coin-sized disks are being produced from the cocoon of the tasar silkworm (Antheraea mylitta). According to Chinmoy Patra, an Indian scientist who now works in Engel’s laboratory, the fibre produced by the tasar silkworm displays several advantages over the other substances tested. “The surface has protein structures that facilitate the adhesion of heart muscle cells. It’s also coarser than other silk fibres.” This is the reason why the muscle cells grow well on it and can form a three-dimensional tissue structure. “The communication between the cells was intact and they beat synchronously over a period of 20 days, just like real heart muscle,” says Engel.

Despite these promising results, clinical application of the fibre is not currently on the agenda. “Unlike in our study, which we carried out using rat cells, the problem of obtaining sufficient human cardiac cells as starting material has not yet been solved,” says Engel. It is thought that the patient’s own stem cells could be used as starting material to avoid triggering an immune reaction. However, exactly how the conversion of the stem cells into cardiac muscle cells works remains a mystery.
