Certain pacemakers vulnerable to hacks, FDA says

A hacker hacking someone’s pacemaker sounds like something that could only happen in a science fiction movie, doesn’t it? Unfortunately,  that reality may be a little too close for comfort. Last month the U.S. Food and Drug Administration (FDA) announced a voluntary recall of 465,000 pacemakers for the potential to be hacked, according to Fortune. The recall raises concerns of how internet-connected medical devices can ensure patient safety. The devices, which provide pacing for slow or irregular heart rhythms, contain “configurable embedded computer systems that can be vulnerable to cybersecurity intrusions and exploits,” according to the FDA alert.

Women’s sight loss highlights lack of stem-cell treatment regulation

Three women who had stem cells injected into their eyeballs at a private clinic in Florida have suffered permanent, severe eye damage from the treatments. The women, who each paid $5,000 to have the stem cells injected to counter the effects of macular degeneration, had fat taken from their stomachs, and stem cells obtained from the fat were then injected into their eyes with catastrophic consequences, described this month in The New England Journal of Medicine. Research into the use of stem cells, which can develop into many other types of cells, may hold great promise in treating tissues damaged ... Read More

Medical device and drug manufacturers among those critical of FDA Guidance Policy

The U.S. Food and Drug Administration (FDA) has been petitioned to reform its guidance process used by drug and medical device makers in order to make the system faster and create a more responsive process. According to the FDA, guidance documents represent the Agency’s current thinking on a particular subject. Critics are accusing the FDA of becoming “sluggish and secretive” when dealing with the guidance process, but FDA attorneys are claiming that the agency is open to reform. Two years ago, Bradley Merrill Thompson, an attorney at Epstein Becker Green, filed a 400-page citizen petition concerning these issues, hoping for a response ... Read More

In 2004, the U.S. Government ... Read More

Studies indicate Lipitor is linked to development of Type 2 diabetes

High cholesterol is a big problem in our country and Lipitor, or its generic counterpart atorvastatin, is one of the leading prescription drugs used to help combat it.

The study suggests that the risk is greatly increased for those who already have risk factors of Type 2 diabetes, such as: excess weight, high blood sugar, high blood pressure and elevated triglycerides. Head researcher Dr. David D. Waters, of the University of California at San Francisco, told Reuters Health in an email that those four factors appear “very ... Read More
