Study finds fault with ICD leads that Abbott inherited from St. Jude Medical
A review of FDA adverse event reports has revealed that some Abbott (NYSE:ABT) implantable cardioverter defibrillator (ICD) leads were much more likely than those made by Boston Scientific or Medtronic to fail due to internal insulation breaches (IBR).
Researchers at the Minneapolis Heart Institute Foundation combed through the FDA MAUDE database from 2008 to 2018 for reports of IBR breaches and other ICD failures. They found that insulation breaches led to 93% of Abbott’s (formerly St. Jude Medical’s) Durata pacemaker lead failures. All 11 failures to treat ventricular tachycardia/ventricular fibrillation were cause...

Double-negative-index ceramic aerogels for thermal superinsulation
In this study, we designed and synthesized hyperbolic architectured ceramic aerogels with nanolayered double-pane walls with a negative Poisson’s ratio (–0.25) and a negative linear thermal expansion coefficient (–1.8 x 10–6 per °C). Our aerogels display robust mechanical and thermal stability and feature ultralow densities down to ~0.1 milligram per cubic centimeter, superelasticity up to 95%, and near-zero strength loss after sharp thermal shocks (275°C per second) or intense thermal stress at 1400°C, as well as ultralow thermal conductivity in vacuum [~2.4 milliwatts per meter-kelvin ...

Simple drug combination creates new neurons from neighboring cells
A simple drug cocktail that converts cells neighboring damaged neurons into functional new neurons could potentially be used to treat stroke, Alzheimer's disease, and brain injuries. A team of researchers at Penn State identified a set of four, or even three, molecules that could convert glial cells - which normally provide support and insulation for neurons - into new neurons. A paper describing the approach appears online in the journal Stem Cell Reports on February 7, 2019.

It ’s Going to Feel like 50 Below in the Midwest This Week. Here’s What Extreme Cold Does to Your Body
Parts of the Midwest are bracing for their coldest temperatures in decades this week, with Tuesday night conditions predicted to feel like 50 degrees below zero or colder in areas of the Dakotas, Minnesota and Iowa, according to AccuWeather. Temperatures in Chicago are also predicted to dip below negative 25 for the first time since the mid-1980s, AccuWeather says.
Health officials have warned residents to stay indoors as much as possible, since the brutal cold can become dangerous in just minutes. But what actually happens to your body in the frigid air? TIME asked Dr. Ronald Furnival, a pediatric emergency physician and ...

Multiple sclerosis -- Helping cells to help themselves
(Charit é - Universit ä tsmedizin Berlin) Diseases such as multiple sclerosis are characterized by damage to the 'myelin sheath', a protective covering wrapped around nerve cells akin to insulation around an electrical wire. Researchers from Charit é - Universit ä tsmedizin Berlin have discovered how the body initiates repair mechanisms which will limit the extent of any damage to this sheath. Their findings, which provide a basis for the development of new drugs to treat multiple sclerosis, have been published in the eminent journal Nature Communications*.

Gambia: Fighting Asbestos Contamination in the Gambia
[UNEP] Discovered about 4,000 years ago, asbestos became widely used by the end of the 19th century in buildings and machinery as an insulation material. Its affordability and useful physical properties, such as sound insulation and resistance to fire, heat and electricity, led to its prevalent use as a construction material all around the world.

Top 10 Mesothelioma and Asbestos News Stories of 2018
The death of renowned thoracic surgeon Dr. David Sugarbaker stunned the mesothelioma community, while asbestos awareness reached new heights in 2018.
The loss of Sugarbaker, who pioneered mesothelioma treatment advances through three decades, was devastating to so many that he touched.
On the other side, companies that continue to ignore the dangers of toxic asbestos were exposed — in the courtroom and in news coverage — about the problems they caused.
Toxic asbestos was found in cosmetics, crayons and on the hands of executives at Johnson & Johnson, which is already paying the price.
Here are the 10 most circulate...

How a Coaxial Alternative Could Make Way for Smaller Catheters
A recent breakthrough in the design of medical device cables is expected to enable a new generation of small, flexible, and intelligent catheters according to Japanese wire and cable supplier Junkosha.
The Tokyo, Japan-based supplier launched its Multi-Channel Transmission (MCT) at MD&M Minneapolis in late October. The new solution could challenge existing twisted pair coaxial and flexible printed circuit technology. Junkosha said MCT will enable new data-rich signals to be used in therapies such as an intracardiac echocardiogram, ultrasound endoscopy, and intervascular ultrasound (IVUS).

Switch for the regeneration of nerve cell insulation
(Ruhr-University Bochum) An international research team has discovered a mechanism that regulates the regeneration of the insulating layer of neurites. This insulation coating, also referred to as myelin sheath, is crucial for rapid signal transmission among cells. Damages to the myelin sheath, such as are caused by multiple sclerosis, can considerably inhibit the function of the nervous system.

Discovery opens new opportunities to slow or reverse MS
(University of Wisconsin-Madison) Nerve cells stripped of their insulation can no longer carry vital information, leading to the numbness, weakness and vision problems often associated with multiple sclerosis. A new study shows an overlooked source may be able to replace that lost insulation and provide a new way to treat diseases like MS.

Rescues, Not Firefight, Prove Emotional for Firefighters
CHICO, Calif. (AP) — Casey Peck had never prayed so hard.
His fire engine was trapped with dozens of cars and panicked people as an inferno roared through the Sierra Nevada foothills town of Paradise on Thursday, hot enough to peel the firetruck's paint and melt its hoses, blowing relief valves designed to withstand 900 degrees and immolating nearby vehicles.
Four people fleeing their flaming cars pounded on the firetruck's doors and were pulled inside, including a nurse from a nearby hospital with her pant leg on fire. The firefighters pressed fire-resistant blankets against the truck's windows to provide insulation aga...
