New wave of MRI-safe pacemakers set to ship to hospitals
This week Medtronic will begin shipping to hospitals in the United States the first pacemaker approved by the FDA as safe for most MRI scans. For consumers, it is a significant step in what is expected to be a wave of new MRI-compatible implanted cardiac devices.
But this is an example of one technology chasing another and the one being chased, the MRI scanner, is changing and is a step ahead of the new line of pacemakers. The pacemaker approved for U.S. distribution is Medtronic’s first-generation pacemaker with certain limitations, while its second-generation MRI-compatible pacemaker is already in use in Europe where approval for medical devices is not as demanding as it is in the U.S. So let’s check out what this is all about — what it means now for current and future heart patients and where it may be headed.
We are all born with a natural pacemaker that directs our heart to beat 60 to 100 times a minute at rest. The pacemaker is a little mass of muscle fibers the size and shape of an almond known medically as the sinoatrial node located in the right atrium, one of four chambers of the heart. The natural pacemaker can last a lifetime. Or it can become defective. And even if it keeps working normally, some point may not function well along the electrical pathway from the pacemaker to the heart’s ventricles which contract to force blood out to the body.
Millions of people in the world whose hearts beat too fast, too slow, or out of sync because their own pacemaker is not able to do the job right, follow their doctors’ recommendation to get an artificial pacemaker connected to their heart to direct its beating. The battery-run pacemaker in a titanium or titanium alloy case the size of a small cell phone, (why can’t it be the size of an almond?) is implanted in the upper left chest, just under the skin, with one or two insulated wire leads connecting to the heart. It can be programmed to run 24/7 or to only operate when the heart reaches a certain state of irregular beating. Read more »

In less than six months after I wrote “Seven Reasons Why Pregnancy Becomes a Deadly Affair,” the public outrage is faint and inaudible regarding domestic violence committed against pregnant women. The subject therefore needs to be revisited again.
On a college campus less than 90 minutes away from my home, a 17-year-old woman was kicked and punched in her abdomen for no apparent reason other than that she carried life within her womb. The alleged father of her baby, Devin Nickels, a college student at Florida State University (FSU), was apparently not happy about his new prospective role. He purportedly contacted a high school buddy, Andres Luis Marrero, who now attended the University of Tampa, and asked him to beat his girlfriend until she had a miscarriage for $200.00. Marrero, instead, offered to assault the girl for free.
According to the University of Tampa’s newspaper, The Minaret, Nickels drove his girlfriend to a secluded wooded area near an apartment complex and Marrero allegedly assaulted her despite her pleas that she was pregnant. The woman was treated at a local hospital and her pregnancy was still viable. Hours later, Marrero allegedly wrote about the attack on his Facebook wall describing it as “fun.” He was subsequently arrested for armed kidnapping and aggravated assault on a pregnant woman. His father made a statement that his son was an “outstanding kid all his life” and he had no idea “where this was coming from.” Nickels was also arrested on the FSU campus.
Unfortunately these travesties continue. The Oakland Press reported the story of a 17-year-old Ypsilanti, Michigan high schooler who allegedly stabbed a classmate (with whom he’d had sex) in the back of the head 12 times because she told him she “might be pregnant.” She ultimately had surgery that resulted in an intensive care unit admission. The classmate lived because she “played dead.” Read more »

Enriched chicken feed may have resulted in eggs having less cholesterol and more Vitamin D than previously measured, reports the U.S. Department of Agriculture (USDA).
A large egg today has about 185 milligrams of cholesterol, down 14 percent from 215 milligrams in 2002, according to new research from the USDA’s Agricultural Research Service, reports USA Today. Also, an egg today has 41 international units (IUs) of Vitamin D, up 64 percent from 25 IUs measured in 2002. (That’s still only about 7 percent of the 600 IUs recommended per day.)
The agency regularly does nutrient checks on popular foods, this time analyzing eggs taken from store shelves in 12 locations around the country. The American Egg Board said in a press release that hen feed is made up mostly of corn, soybean meal, vitamins and minerals. Nutrition researchers at Iowa State University are also looking into reasons why cholesterol in eggs is decreasing.
The government’s “Dietary Guidelines for Americans” recommend that most people eat less than 300 milligrams of total dietary cholesterol a day, and people at a high risk of cardiovascular disease should eat less than 200 milligrams a day. The average American man consumes about 337 milligrams of cholesterol a day and the average woman consumes 217 milligrams, reports the Los Angeles Times.
One egg a day fits within the average, healthy American’s diet, reports WebMD, citing research funded by the Centers for Disease Control and Prevention and by the American Egg Board — owners of the slogan “the incredible, edible egg.”

From an AP article in the Dallas-Fort Worth Star-Telegram:
AUSTIN — Texas medical regulators on Friday placed on probation a West Texas doctor involved in the unsuccessful prosecution of two nurses who complained anonymously that the physician was unethical and risking patients’ health.
The Texas Medical Board technically suspended Dr. Rolando G. Arafiles Jr. but allowed him to continue to practice medicine while on probation for four years if he completes additional training.
The board also said Arafiles must be monitored by another physician and submit patient medical and billing records for review. The monitor will report his or her findings to the board.
In the mediated order signed in Austin, the board concluded that Arafiles failed to treat emergency room patients properly, did not apply hormone therapy to a female patient appropriately and failed to document patient diagnoses and treatment plans.
The board also found that Arafiles improperly tried to intimidate two nurses who reported him to the medical board for unethical behavior.
Ugh.

Reuters Health reports that more than a quarter of Americans taking antidepressants have never been diagnosed with any of the conditions the drugs are typically used to treat, according to new research published in the Journal of Clinical Psychiatry. An excerpt:
“We cannot be sure that the risks and side effects of antidepressants are worth the benefit of taking them for people who do not meet criteria for major depression,” said Jina Pagura, a psychologist and currently a medical student at the University of Manitoba in Canada, who worked on the study.
“These individuals are likely approaching their physicians with concerns that may be related to depression, and could include symptoms like trouble sleeping, poor mood, difficulties in relationships, etc.,” she added in an e-mail to Reuters Health. “Although an antidepressant might help with these issues, the problems may also go away on their own with time, or might be more amenable to counseling or psychotherapy.”
