Internal bleeding higher with HeartMate II device than earlier model

DETROIT – The incidence of internal bleeding was higher in the most commonly implanted heart device than in an earlier model, according to two studies at Henry Ford Hospital in Detroit.

The HeartMate II, a left ventricular assist device (LVAD) is a continuous-flow mechanical pump connected to the patient's heart that takes over the pumping of the weakened heart's left ventricle.

Important monitoring of heart performance is omitted in two-thirds of high-risk surgical operations

Amsterdam, The Netherlands: Only 35% of anaesthesiologists are carrying out a simple procedure during high-risk surgery that can make a significant impact on how well patients recover from their operations, according to new research presented today (Sunday 12 June) at the European Anaesthesiology Congress in Amsterdam.

Hypnosis/local anesthesia combination during surgery helps patients, reduces hospital stays

Amsterdam, The Netherlands: Using a combination of hypnosis and local anaesthesia (LA) for certain types of surgery can aid the healing process and reduce drug use and time spent in hospital, anaesthesiologists have found. The combination could also help avoid cancer recurrence and metastases, according to new research to be presented today (Sunday) at the European Anaesthesiology Congress in Amsterdam.

Two isolates from E. coli outbreak available

An outbreak of Escherichia coli causing a severe illness called hemolytic-uremic syndrome (HUS) began in Germany on May 2, 2011 and has killed more than 20 people and sickened more than 2,000. The organism causing the outbreak has been identified as a strain of E. coli O104:H4 that produces a Shiga toxin and causes an illness similar to infection with E. coli O157:H7. Two isolates from this outbreak have been sequenced.

Hormone test helps predict success in IVF

PROVIDENCE, R.I. [Brown University] — Given how much patients invest in in vitro fertilization (IVF), both financially and emotionally, tools to inform couples about what they might expect during their treatment can be welcome. A study by researchers at Brown University and Women & Infants Hospital shows that as the IVF cycle is beginning, a blood test for levels of a hormone called AMH, or antimullerian hormone, can help predict the number of eggs that will be harvested.

Johns Hopkins researchers link cell division and oxygen levels

Cells grow abundant when oxygen is available, and generally stop when it is scarce. Although this seems straightforward, no direct link ever has been established between the cellular machinery that senses oxygen and that which controls cell division. Now, in the June 10 issue of Molecular Cell, researchers at Johns Hopkins report that the MCM proteins, which promote cell division, also directly control the oxygen-sensing HIF-1 protein.

Quitlines help smokers quit regardless of recruitment method

Proactive telephone counseling helps smokers quit regardless of how they are recruited to a telephone quitline, according to a study published online June 10th in the Journal of the National Cancer Institute.

Smokers who use telephone counseling quitlines may do so in response to active recruitment methods, such as physician referral or direct mail or phone calls, or passive methods, such as posters or television ads. Whether quitlines are equally effective for actively recruited smokers and passively recruited smokers has been a key question.

Landsat satellite images compare before and after Massachusetts tornado

Satellites provide a lot of useful information and the Landsat 5 satellite captured an image of the long damage track created on June 1, 2011 when a tornado tracked from Springfield to Sturbridge, Mass. An earlier image is now available from 2010 that enables people to more clearly see the damage path the June 2011 twister created on its eastward track.

A Landsat 5 satellite image from October 8, 2010 has been released from NASA and the U.S. Geological Survey that shows the area between Springfield and Sturbridge, Mass. where the tornado touched down.

Significant litter of cheetah cubs born at Smithsonian Conservation Biology Institute

Five cheetah cubs were born May 28 to 6-year-old Amani at the Smithsonian Conservation Biology Institute in Front Royal, Va. Amani is a dedicated mother according to keepers, who have observed her nursing and grooming the cubs.

Social scientists study impact of human adult stem cell research

New research says studying both adult and embryonic stem cells can benefit medical science, but banning the study of either type could harm studies of the other.

Researchers from the University of Michigan, Stanford University and the Mayo Clinic in Rochester, Minn. recently investigated whether the increased number of studies with a certain type of adult stem cell has changed the overall course of research in the field.

New substances added to HHS Report on Carcinogens

The U.S. Department of Health and Human Services today added eight substances to its Report on Carcinogens, a science-based document that identifies chemicals and biological agents that may put people at increased risk for cancer.

USDA-led consortium sequences genome of key wheat pathogen

A U.S. Department of Agriculture (USDA)-led consortium of scientists has fully sequenced the genome of the pathogen that causes the wheat disease known as septoria tritici blotch, which can cause significant yield losses.

U-M researchers find potential new way to fight sepsis

ANN ARBOR, Mich. — By digging a little deeper, researchers may have found a potential target for reversing the deadly blood infection sepsis.

Scientists at the University of Michigan Health System looked at microRNA, a type of RNA that does not code for a protein itself but that can regulate the expression of other genes and proteins. They found that by attacking the right microRNA they could influence a key trigger of inflammatory diseases such as sepsis.

An egalitarian Internet? Not so, UGA study says

Athens, Ga. – The Internet is often thought of as a forum that enables egalitarian communication among people from diverse backgrounds and political persuasions, but a University of Georgia study reveals that online discussion groups display the same hierarchical structure as other large social groups.

Strength training for grandma and grandpa

People lose 30% of their muscle strength between the ages of 50 and 70 years. However, maintaining muscle strength in old age is enormously important in order to maintain mobility and to be able to lead an independent life and manage everyday tasks independently. In the current issue of Deutsches Ärzteblatt International, Frank Mayer and colleagues from the University of Potsdam conclude that progressive strength (resistance) training counteracts muscular atrophy in old age (Dtsch Arztebl Int 2011; 108(21): 359-64).
