They Are Young And Need The Job: A Second Chance For Dangerous T Cells
The immune system"s T-cells react to foreign protein fragments and therefore are crucial to combating viruses and bacteria. Errant cells that attack the body"s own material are in most cases driven to cell death. Some of these autoreactive T-cells, however, undergo a kind of reeducation to become "regulatory T-cells" that keep other autoreactive T-cells under control. A group led by immunologist Professor Ludger Klein of LMU Munich has now shown that the developmental stage of an autoreactive T-cell is decisive to its ultimate destiny. Young autoreactive T-cells are very readily reeducated into regulatory T-cells. Under identical conditions, however, older T-cells become fully activated and can cause damage - they are in a way resistant to reeducation. "We now intend to study at the molecular level what makes a T-cell accessible for reeducation," said Klein, "because then it may be possible to convert even normal adult T-cells, which can be obtained easily and in great numbers from blood. Possibly, they could then be used as regulatory T-cells in therapies for autoimmune diseases such as type-1 diabetes or multiple sclerosis: these are diseases that are triggered by uncontrolled autoreactive T-cells."

Investigation Finds Problem Nurses Stay On Job Amid Nursing Shortage

Propublica/The Los Angeles Times found that "the board charged with overseeing California"s 350,000 registered nurses often takes years to act on complaints of egregious misconduct, leaving nurses accused of wrongdoing free to practice without restrictions ... It"s a high-stakes gamble that no one will be hurt as nurses with histories of drug abuse, negligence, violence and incompetence continue to provide care across the state. While the inquiries drag on, many nurses maintain spotless records. New employers and patients have no way of knowing the risks." Some of the article"s key findings include: "The board took more than three years, on average, to investigate and discipline errant nurses, according to its own statistics. In at least six other large states, the process typically takes a year or less. ... [It] failed to act against nurses whose misconduct already had been thoroughly documented and sanctioned by others. ... [It] gave probation to hundreds of nurses - ordering monitoring and work restrictions - then failed to crack down as many landed in trouble again and again. ... The board failed to use its authority to immediately stop potentially dangerous nurses from practicing. It obtained emergency suspensions of nurses" licenses just 29 times from 2002 to 2007 (Ornstein, Weber and Moore, 7/11). Meanwhile, the Orlando Sentinel reports on how the nursing shortage is affecting Florida: "Florida lacks enough new nurses to make up for the large numbers of nurses approaching retirement age within the next decade, according to a May report by the Florida Center for Nursing. The shortage is not just driven by the impending retirements of nurses, but also an aging baby boom population that will require more health care in the coming years." Mary Lou Brunell, executive director of the Florida Center for Nursing, said the shortage "poses a serious threat to the quality and availability of health care in Central Florida and throughout the state." The paper notes "the lack of qualified faculty and competitive wages for nurse educators are major obstacles. More than 12,000 qualified applicants were turned away from state nursing education programs in 2007-2008. Because salaries for nurses can be considerably higher than educators, many choose health care over teaching" (Quintero, 7/13).
