A new 3D printed membrane acts like an artificial pericardium to continuously monitor and regulate the heart's beating
They wash dishes in restaurants, clean toilets and look after elderly incontinent people in the West. That makes the majority of the 30 million who have emigrated from Africa. Some are much luckier, they work in subaltern management positions in corporate America or in public institution in Europe. Few are real stars, successful with high pay and social status. Regardless of their current fate, they all share one thing in common: most of them want to return to Africa. The recent medias’ drumbeat about “Africa is Rising” is making them restless and hopeful because most of them have quite a petty life in the West. They are constantly harassed by the state police, crushed by daily racism from their neighbors and strangers, economically and politically isolated, and with very little hope for a near-future improvement. Unfortunately their dream to return home is painfully held back by deep fears and unanswered questions. Here are the top 10 fears of the African diaspora about Africa, and also the top 10 questions most of them are confronted with.
“The gap between what patients and doctors expect from these procedures, and the benefit that they actually provide, shows the profound impact of a certain kind of mechanical logic in medicine,” he explains. “Even though doctors value randomized clinical trials and evidence-based medicine, they are powerfully influenced by ideas about how diseases and treatments work. If doctors think a treatment should work, they come to believe that it does work, even when the clinical evidence isn’t there.” [more inside]

Last Saturday 23-year old professional soccer player Fabrice Muamba suffered cardiac arrest while playing in front of a packed stadium. The medical staff rushed to his aid, as did a cardiologist who happened to be in the crowd. Muamba's heart was stopped for 78 minutes, but he survived and seems to be making good progress. Here, the doctors involved tell their remarkable stories of the incident.
"Nature is not always the best designer, at least when it comes to things that humans must build and maintain. So the newest artificial heart doesn’t imitate the cardiac muscle at all. Instead, it whirs like a little propeller, pushing blood through the body at a steady rate. After 500 million years of evolution accustoming the human body to blood moving through us in spurts, a pulse may not be necessary. That, in any case, is the point of view of the 50-odd calves, and no fewer than three human beings, who have gotten along just fine with their blood coursing through them as evenly as Freon through an air conditioner."

Continuous Chest Compression CPR is a hands-only CPR method that doubles a person’s chance of surviving cardiac arrest. It’s easy and does not require mouth-to-mouth contact, making it more likely bystanders will try to help, and it was developed at the University of Arizona College of Medicine. YT link for the video.

Atkins was right?! According to a meta-study of nearly 350,000 people, "there is no significant evidence for concluding that dietary saturated fat is associated with an increased risk of (heart disease) or (vascular disease)... However, replacement with a higher carbohydrate intake, particularly refined carbohydrate, can exacerbate ... insulin resistance and obesity that includes increased triglycerides, small LDL particles, and reduced HDL cholesterol. Dietary efforts to improve ... (cardiovascular disease) risk ... should primarily emphasize the limitation of refined carbohydrate intakes and (losing weight)." [more inside]

Young@Heart. What started as a 2006 British television documentary and became an audience favorite at the Los Angeles and Sundance film festivals in 2007 and 2008 opens across the United States this weekand will soon open in France, Belgium, Switzerland, Germany, Japan and Australia. The opening sequence showing Eileen Hall , then 92 , singing the 1982 hit from punk-rock group The Clash provided the inspiration for director Stephen Walker when he first saw the group on stage in London in 2005. Besides giving new meaning to lyrics from popular hits, the film is comedic and poignant as it explores friendship, old age and death.
So apparently it's not the lack of oxygen which causes cells to die. Rather, getting oxygen back, which triggers the same cell death mechanism that guards against cancer, causes cell death.
Trial by Transplant. "Most transplant recipients are grateful beyond measure. Amy Silverstein's view, after nearly two decades with a donated heart, is more conflicted and often bleak. Much of her life, as described in Sick Girl, has revolved around nauseating drugs, ongoing fatigue, painful tests, ER visits and hospitalizations without end—and the constant fear that the next heartbeat could be her last. At low ebb, she has teetered on the edge of giving up."

Save a Child, Save the World On November 29, 1944, Dr. Alfred Blalock made an incision in the chest of young Eileen Saxon. He was about to perform an operation suggested by a dyslexic, nearly deaf woman and perfected by an African American. Assisting in this madness were two men who would also become giants in their field. Cardiac Surgery has progressed to the point that having a Congenital Heart Defect isn't always fatal. In fact, there are enough adults living with heart defects that there is an organization supporting Adult Chongenital Heart Defect research and education. While there is a great movie about the operation and Thomas covers it in his book, we still don't know one important fact: Did Blalock rub the toe that morning?

Human cardiac catheterization was introduced by Werner Forssman in 1929. Ignoring his department chief, and tying his assistant to an operating table to prevent her interference, he placed a ureteral catheter into a vein in his arm, advanced it to the right atrium [of his heart], and walked upstairs to the x-ray department where he took the confirmatory x-ray film. In 1956, Dr. Forssman was awarded The Nobel Prize. [via the "fortune" command]

Soccer Penalty Shoot-Outs Cause Heart Attacks English reasearchers have determined heart attacks increased shortly after an England/Argentina match that ended in a penalty shoot out. They conclude that in the interest of public health, penalty shots should be abandoned. Are they seriously saying this with a straight face? And what on earth prompted such a study?
One Good Turn Deserves Another Mantaine Minis, 6, was living in a hut in a remote village in Kenya, in need of lifesaving heart surgery, when the improbable happened one day in June. A group of students and parents from the Langley School in McLean (Virginia) as on safari at the Masai Mara National Reserve, where Mantaine's father is a game warden. That's when someone from the village told a Langley teacher about Mantaine's heart problem. From there, things seemed to unfold quickly.
