Biologist’s find alters the bacteria family tree

BlankCarrine Blank, Ph.D. , assistant professor of earth and planetary sciences in Arts & Sciences, has found that the currently accepted dates for the appearance of oxygen-producing bacteria and sulfur-producing bacteria on the early earth are not correct. She believes that these bacteria appeared on earth much later than is now believed.

Researchers calculate cost-savings of living kidney donors

Some 3,000 others died on the waiting list. Part of the problem involves obtaining donated organs. Currently only half of potential organ donors actually donate, but even if every eligible donor donated, many on the waiting list still wouldn’t be helped. Living donors are another potential source of organs, and the transplants from living donors also have the greatest chance of success. Encouraging more people to donate a kidney while they are alive could put a big dent in the number of people on the waiting list, but how can society encourage more of those people to donate? Researchers at Washington University School of Medicine in St. Louis and the University of Minnesota set up a mathematical model to determine whether it might be cost effective to pay people for their kidneys. Potential ethical issues aside, the researchers determined that society could break even by paying as much as $90,000 to those willing to part with a kidney for money.

Dramatic improvements in patient safety in the ICU

ICU personnel are instructed in proper placement of catheters to lower infection risk.Because patients in intensive care units (ICUs) are, by definition, in dire health, the consequences of even the slightest medical error can be devastating. Now two quality-improvement studies by researchers at Washington University School of Medicine in St Louis suggest solutions to two of the most common and dangerous patient safety challenges in ICU patients: restoring normal phosphorus levels and preventing infections related to catheters. The research was a multi-disciplinary effort between physicians, nurses, dietitians and the rest of the surgical ICU team at Barnes-Jewish Hospital. The quality-improvement studies led to dramatic improvements in patient health and safety, and the team believes these initiatives could improve patient health and safety at any ICU in the country.

Safe and secure

According to the U.S. Centers for Disease Control and Prevention (CDC), car crashes are the leading cause of death for children. Almost 2,000 children age 14 and under are killed in automobile crashes each year and another 280,000 are injured. Proper use of car seats reduces the risk of death significantly — by as much as 71 percent for infants and by about 55 percent for toddlers. The CDC also estimates that 50,000 serious injuries could be prevented and 455 lives saved each year if all children under 5 used safety seats. In spite of the dangers, 40 percent of American children 4 and under routinely ride unrestrained. But Emergency Department physicians at Washington University School of Medicine and Barnes-Jewish Hospital in St. Louis are trying to change that. They are targeting low income families, training them in proper use of child safety seats and then giving those families gift certificates that can be redeemed for the seats. The Safe and Secure program hopes to cut down on deaths and injuries from car crashes by providing more than 2,000 free car and booster seats to Missouri families who live below the poverty level as determined by Medicaid.

Brain activity, including memory-processing, changes in Tourette syndrome

Scientists have known for years that abnormal activity involving a brain chemical called dopamine is somehow connected to the movements and vocalizations, or tics, associated with Tourette syndrome. Now neuroscience researchers at Washington University School of Medicine in St. Louis have found brain activity in these patients is abnormal during memory tasks as well.
