  • The tablet-based app, called CHAMP (Cardiac High-Acuity Monitoring Program)
  • The 3,000 children in the U.S. with a single ventricle heart defect typically require three surgeries -- one within several days of birth, one within six months of birth and one between three and five years of age. Nationally, ten to twenty percent of babies who have had the first surgery die before having the second surgery
  • Previously, patients were monitored with a paper-based, "three-ring binder" system, which created a heavy responsibility for families, was hard to maintain accurately and was difficult to share with physicians in a timely manner when rapid interventions may be necessary. In contrast, the app gathers both automated and manually-entered data that is directly fed into a database and the EMR for constant monitoring and analysis by their care team. This includes oxygen saturation levels measured by a Bluetooth pulse oximeter, manually-entered weight and feeding logs, and 15-second videos of breathing that have proven invaluable to doctors as they monitor their patients' healing.

  • In addition to reducing the stress, burden and decisions these families currently face, the app will benefit countless future patients through analysis of its use over time.
  • database will become an unprecedented source of knowledge about these high-risk, single ventricle heart defect patients that will accelerate learning and shape their care.

  • Researchers are very interested in leveraging these circulating tumor cells, or CTCs, which have the potential to allow the properties of a tumor to be better understood without a biopsy, and may also help physicians recognize how aggressive a tumor is and whether it is likely to cause metastatic disease.
  • Recent discoveries have shown that CTCs are highly heterogeneous -- with individual cancer cells possessing very different molecular characteristics -- and that only a small subset of these cells actually possess the metastatic potential to spread the disease throughout the body.
  • Current technologies exist that allow these circulating cells to be captured from the blood of cancer patients, but they are not well equipped to differentiate between the various CTCs present in the blood sample
  • ...8 more annotations...
  • . Instead, they simply count the number of CTCs in a patient sample, rather than identifying the cells that possess the highest metastatic potential. As a result, these tools are less than ideal as they are only able to provide general information on the levels of CTCs rather than a more focused understanding of the disease and its aggressiveness.
  • Researchers at the Leslie Dan Faculty of Pharmacy at the University of Toronto have developed a new device that provides a way to visualize the heterogeneity of CTCs, and have published their findings in the Chemistry journal Angewandte Chemie.
  • "Ultimately, we believe that this sensitive technology possesses the potential to provide more useful information about these cells, leading to better diagnoses and improved patient outcomes," notes Dr. Kelley.
  • "Recognizing that characterizing the phenotype of circulating tumor cells is more useful for cancer management than quantitating the cells present in a blood sample, we set out to devise a method that would allow us to capture and distinguish between these cells,
  • In the lab, we were able to demonstrate that the tool was not only highly effective at differentiating these cells, but also proved to be more sensitive than the current leading methods of cellular sorting."
  • esearchers collected samples from prostate cancer patients to test the efficacy and ability of the diagnostic platform.
  • Using nanoparticles to tag cells, this device sorts the CTCs collected in a sample into discrete subpopulations based on the phenotype of the cells, and provides a snapshot of the nature of the tumor cells present in patients' blood.
  • excited to pursue new research opportunities in an effort to more accurately and less invasively diagnose and improve the health outcomes for cancer patients."

  • The new approach would potentially reduce the number of surgeries the patients have to undergo in the first six months of life from two to just one
  • it would also create a more stable circuit for blood to flow from the heart to the lungs and the rest of the body within the first days and months of life.
  • Engineers ran computer simulations of the surgery and found it would reduce the workload on the patient's heart by as much as half. It would also increase blood flow to the lungs and increase the amount of oxygen the body receives.
  • ...12 more annotations...
  • Currently, they undergo three surgeries by age three.
  • The first surgery is performed in the first few days of life and installs a small GoreTex tube to connect the pulmonary arteries with a blood vessel off the aorta. That 3.5-millimeter shunt becomes the only source of blood to the infants' lungs -- essentially their only source of oxygen. There is a 30 percent mortality rate associated with this surgery.
  • Between 3 to 6 months, surgeons remove the shunt and connect the superior vena cava to the pulmonary artery. At that stage, half the blood flow needed for oxygenation goes through this circuit created by the physicians.
  • At around age 3, a third surgery, called a Fontan, connects both the inferior and superior vena cava to the pulmonary arteries, usually in a T-shaped configuration. Experience has shown that jumping directly to the second step too early in the child's life, without allowing sufficient time for patients to grow, resulted in very high fatality rates for pediatric patients.
  • This would create what's known in fluid mechanics as an ejector pump
  • Engineers are proposing to combine the first and second steps of the surgery, with a small modification.
  • he clipped shunt creates what's called a Venturi effect, driving a low-pressure flow stream with an injection of a high-pressure flow stream and causing the speed of the blood flow to increase.
  • The shunt could be closed later, when circulation improves, via a catheter -- a much less invasive procedure.
  • n 2009, she and colleagues proposed a custom-made Y-shaped design for the Fontan surgery, rather than the traditional T-shaped connection used. In 2010-11, six patients underwent a Y-graft surgery at Stanford University.
  • Researchers also found that the Y-graft reduced energy losses in the blood flow and distributed blood flow more evenly to both lungs.
  • Marsden and her colleagues hope that SimVascular may be used in the future to impact a wide range of cardiovascular surgeries and devices in children and adults.
  • They propose to have the shunt, slightly clipped, go into the superior vena cava, while also connecting the superior vena cava to the pulmonary arteries.

  • Researchers have created a new neural interface to provide sensory information from an artificial hand to the brain
  • ...10 more annotations...
  • This interface is able to link the patient's nervous system with the artificial sensors, embedded in the prosthesis, enabling the user to control complex hand and finger movements.
  • researchers first had to develop a selective, implantable neuro-interface.
  • the electrodes have an interface with some areas of the nerves and not with others close by,
  • next stage is to identify two or three people to test the prosthesis over some years, with all the elements being portable, wearable or implanted.
  • enhanced the artificial hand with sensors that detect information about touch, which is sent in real time to the patient, allowing for the natural control of the hand.
  • Dr Silvestro Micera . Micera and his team
  • Dr Micera firmly believes the prosthesis will be available in ten years time.
  • NEBIAS is a continuation of intensive multi-disciplinary research in this field which started many years ago with the CYBERHAND  (Future and Emerging Technologies) (FET) FP5 Project (2002-2005)
  • You can draw on a pool of over 500 million inhabitants to find the best researchers in different fields.'
  • NEBIAS, also, was launched at the start of November 2013 and will run for four years. It receives EUR 3.4 million from the European Commission's 7th Framework Programme .

  • Target last month became one of the first retailers to begin quietly testing a technology known as CurrentC, created by a group of retailers called the Merchant Customer Exchange.
  • confirmed that a group of Target’s headquarters employees has been trying out the CurrentC app in a couple of dozen Target stores around the Twin Cities.
  • It didn’t help matters that its system was hacked last week and that e-mail addresses of those in the pilot program were compromised, raising questions about its security.

  • Apple launched Apple Pay, which can be used at a couple of dozen major retailers such as Macy’s and McDonald’s
  • U.S. Bank said users of its credit and debit cards could add them to Apple Pay and use new iPhones to pay for things directly from their accounts at the bank.
  • Rite Aid and CVS turned off the ability of customers to use Apple Pay in its stores, ostensibly because they belong to Merchant Customer Exchange, raising questions about its exclusivity agreements.
  • retailer is focused right now on adding chip-and-pin technology to its checkout lanes to provide the way for more secure credit card payments in the wake of Target’s huge data breach last year.
