ϟ Israel saving the world again: An Artificial pancreas
MD-Logic mimics the workings of the pancreas, monitoring blood sugar levels and delivering insulin automatically, even at night.
In people with diabetes, the pancreas doesn’t produce or release insulin as it should, so the body can’t metabolize sugars properly. That means blood sugar levels have to be monitored continuously, even (and especially) at night, when diabetics’ blood sugar can get dangerously out of control.
But nighttime monitoring and dosing is a sleep-stealing activity, particularly for parents of diabetic children.
A new artificial pancreas developed in Israel may allow them sweeter dreams. The MD-Logic was recently tested on Israeli children at an overnight diabetes summer camp, to resounding success.
The key is that the device’s software “thinks” like a physician, says one of its developers, Eran Atlas of the Schneider Children’s Medical Center in Tel Aviv.
Using existing insulin pump technology, MD-Logic closes the loop between a continuous glucose monitor and insulin pump, allowing patients to self-regulate their glucose levels and deliver the exact amount of insulin needed, when needed — even at 3 o’clock in the morning.
ϟ Israel saving the world, again
From Israel 21C:
This is huge, as hospitals are breeding grounds for the most dangerous strains of bacteria. Tens of thousands of lives could be saved.Every patient, nurse, doctor and visitor to a hospital knows the drill: hands get a splash of antibacterial fluid found at every bedside, entrance and exit. Keeping hands clean can prevent some infections, but superbugs — those sometimes deadly bacterial strains resistant to antibiotics — can outwit the best hygiene practices.
Hospital-acquired infections are one of the leading causes of preventable death in the developed world today, with 100,000 people in the United States alone dying every year from bugs they catch as patients in the hospital, according to the World Health Organization. The old and very young are at an especially high risk of infection from resistant bacteria that can spread like wildfire.
But now superbugs may have met their match, thanks to a genetically engineered cleaning solution developed in Israeli laboratories.
Costing only a few dollars a quart, the solution is non-toxic to patients and can be spread on hospital surfaces to kill what conventional soaps and antibiotics can’t, report researchers Rotem Edgar from the Tel Aviv Sourasky (Ichilov) Medical Center and Udi Qimron from Tel Aviv University. They detailed their technology recently in the journal Applied and Environmental Microbiology.
The solution uses a laboratory-grown virus called a bacteriophage, which disrupts the DNA of resistant bacteria and renders them susceptible to antibiotics.
“We have genetically engineered the bacteriophages so that once they infect the bacteria, they transfer a dominant gene that confers renewed sensitivity to certain antibiotics,” says Qimron, who believes his solution will one day be part of every hospital’s anti-germ arsenal.
The researchers say that the new spray could be applied on any surface where there is a high concentration of germs, such as door handles, faucets, bedrails and handrails.
“Our novel approach relies on an effective delivery process and selection procedure, put on the same platform for the first time,” says Qimron, suggesting that it will knock out all kinds of bacteria, reducing the infection rate from even non-resistant bacteria.
This solution, the researchers note, should be part of a two-step process to neutralize bacteria in the hospital effectively. The second part of the process is a compound called Tullurite. This would be spread over the surfaces to kill any remaining bacteria not sensitized by the new advance. The two-step cleaning combination would first disarm the bacteria and then go on to kill those that are still dangerous, they say.
Like all medical products, the new spray needs to be tested in a clinical setting before being approved for sale.
