Surgeons cut and reposition hip bones to reduce pain.When an older person has a hip problem, surgeons often replace the damaged hip with an artificial one. But that’s not a good option for someone in their 20s or 30s, so orthopaedic surgeons at the School of Medicine are repairing damage to the hip to prevent arthritis without having to replace the hip joint.

StewartCan Martha Stewart regain the trust of her customers or could Enron’s former chief Ken Lay get a new job under the clouds of suspicion left in the wake of their legal problems? It depends upon the match between how they respond to the allegations and the extent to which the alleged offense is perceived to involve their integrity or their competence, according to a recent study by Washington University in St. Louis professor Kurt T. Dirks and three colleagues.

KaramustafaSince Sept. 11, 2001, a leading scholar of Islam at Washington University in St. Louis has sought to help an inquiring American public separate stereotype from complex reality and Islamic extremists from the many-sided moderate majority. Ahmet Karamustafa, Ph.D., chair of the Religious Studies program in Arts & Sciences at Washington University in St. Louis, is trying to help Americans see that although Islam has its radical factions, these factions are small in number and the majority of the world’s Muslims are peaceful people.

A biomedical engineer at WUSTL has determined love taps are better than love jolts in addressing defibrillation.When it comes to affairs of the heart, love taps are preferred over love jolts. That is the result of a team of heart researchers including Igor Efimov, Ph.D., associate professor of biomedical engineering at Washington University in St. Louis, trying to effect a better implantable heart defibrillator. Efimov and his colleagues have modeled a system where an implantable heart defibrillator focuses in on rogue electrical waves created during heart arrhythmia and busts up the disturbance, dissipating it and preventing cardiac arrest.

In November, 26 incumbent U.S. senators will be on election ballots. Chances are, most of them will win, according to a study by Washington University in St. Louis professor Gautam Gowrisankaran and two colleagues.

Ritonavir may slow bone loss in AIDS patients.In a collaborative study initiated by their clinical colleagues, scientists at the School of Medicine have shown that the AIDS drug ritonavir suppresses the creation and activity of cells that dismantle bone, potentially slowing bone loss and lowering the risk of osteoporosis in AIDS patients. The findings may encourage clinicians to consider permanently keeping ritonavir or a similar bone-sparing drug in the changing mixture of treatments for AIDS patients.

President George W. Bush’s recent push for the establishment of an ownership society features partial privatization of Social Security by diverting a portion of the payroll tax into individual accounts. “Privatizing Social Security is a dangerous idea,” says Merton Bernstein, a nationally recognized expert on Social Security. “Despite widespread criticism and misunderstanding, Social Security is in good shape for the future and its funding can be made solid by modest measures. In contrast, privatization would cost $3.75 trillion.”

Studying elderly people with mild to moderately elevated blood pressure, researchers at the School of Medicine have found that exercise is just as effective as blood pressure medicine at reducing heart mass and the thickness of the heart wall. Exercise also provided benefits that blood pressure medicine did not, such as lowering an individual’s risk of developing diabetes.

Many Americans are faced with the fear of going hungry.Most Americans don’t think they’ll ever be faced with the question of how they will get their next meal, but a recent study co-authored by a social welfare expert at Washington University in St. Louis shows that at least 42 percent of the U.S. population will deal with food insecurity during their lifetime. “Food insecurity goes beyond the fear of going hungry,” explains Mark R. Rank, Ph.D., the Herbert S. Hadley Professor of Social Welfare at the university’s George Warren Brown School of Social Work. “Food insecurity means that people are unable to provide themselves and their families nutritionally adequate food on a regular basis.

B cellsScientists at the School of Medicine have identified a protein that can reduce the chances immune B cells will erroneously attack the body’s own tissues, causing autoimmune disorders like lupus, allergies, arthritis and diabetes. The protein is the first of its kind to be identified in B cells and could provide scientists with a new target for treating such conditions.
