Implanted Bioprosthetic Heart In Patient

In a groundbreaking surgery proceeded a team of doctors at the hospital Georges Pompidou in Paris who implanted for the first time in the world, an autonomous, bioprosthetic artificial heart, made ​​by the French company Carmat, in a patient suffering from end-stage heart failure. "Implantation unfolded in a satisfactory manner.

The patient is under medical supervision, is awake and conversing with their relatives ", the company announced. In late September, the French authorities had given their approval for this surgery, giving new hope and perspective to heart patients who are condemned because of the lack of donor organs. "We are pleased that the first implantation, but obviously it would be premature to draw conclusions after going for a single implant and even the time that has passed since the surgery is very small" commented general manager Marcello Carmat Konviti. Founded by French surgeon Alain Karpentie, who is known worldwide for its cardiac valve Karpentie-Edwards who has invented.

The aim is to cover the shortage of grafts as many people suffering from heart failure at an advanced stage die before a suitable donor is found. "Artificial heart fully mimics the human heart with two ventricles that promote blood in the same way you did and heart muscle, with sensors that allow it to increase or decrease the rate. When the patient is asleep, the rate drops when going upstairs, increases. Consequently, not related to mechanical pump, "he explained before some months the company cofounder Philip Pouleti. Patient in which the heart was implanted last Wednesday suffering from heart failure at the last stage. The doctors did not give him much room for life and there was no other alternative treatment. Carmat The claims that the artificial heart could save each year tens of thousands of patients, guaranteeing their quality of life unprecedented, without running the risk of organ rejection.

Head Injuries Triple The Risk Of Premature Death

Severe head injuries-such as that suffered by Michael Schumacher recently-triple the risk of premature death, even several years after the incident, according to a new British-Swedish scientific research. The main causes of premature death are suicide and fatal young-this-time injuries, eg in a car accident or fall due. But even the less serious head injuries increase the risk of premature death, according to the survey.

Thus, people who once suffered concussion, eg during a sport like football, are twice as likely to die prematurely compared with the general population. Road, falls and sports are the main causes of head injuries. At greatest risk are those with a history of psychiatric disorder before the initial trauma, and injury often exacerbates preexisting problem and blurs the clarity of mind, and therefore more easily fall victims of poor judgment or miscalculation, resulting in new fatal injuries .

Researchers at the Department of Psychiatry, University of Oxford , from University College London and the medical Karolinska Institutet in Stockholm, led by Dr Sina Feizel, made ​​after publication in the journal Psychiatry of the American Medical Association "JAMA Psychiatry", in accordance with the BBC, looked at data on more than 2 million people, which covered a wide period of 40 years (from 1969 to 2009). Each year, more than one million people in Europe and 1.7 million in the U.S. admitted to a hospital because head injury, which has caused a skull fracture, internal bleeding, loss of consciousness for more than an hour or a combination of the above. Several, however, survive the initial period of risk, estimated at six months after their injury. Evidence shows that, without a prior brain injury, 0.2% of people die prematurely before the age of 56 .

However, the rate of premature deaths tripled (0.6%) if elapsed brain trauma and ejected at 4% for persons, other than trauma, have a mental disorder, such as depression. Researchers say the brain injuries tend to cause permanent damage to neural networks and thereby adversely affect the ability of former victims to properly handle the various situations faced then, for example when driving.
