A new University of Michigan study shows that institutions use different methods to measure blood stream infections. Bloodstream infections are the most common hospital-associated infections in pediatric intensive care units (PICUs) and a significant source of in-hospital deaths, increased length of stay and added medical costs. The study’s findings, published in the October issue of the American Journal of Infection Control, offer a compelling opportunity for hospitals to improve their CA-BSI surveillance as a means to promote valid comparisons among institutions. Current publicly reported data show that some hospitals report a four-fold difference in infection rates.
Researchers have determined the genetic structures of 13 previously unmapped strains of the bacterium that causes Lyme Disease. These findings may accelerate progress toward vaccines and more effective treatments.
A study by two Florida State University biochemists makes an important contribution to science’s understanding of a serious problem causing concern worldwide: the growing resistance of some harmful bacteria to the drugs that were intended to kill them.
William R. Jacobs, Jr., Ph.D., professor of microbiology & immunology and of genetics at Albert Einstein College of Medicine of Yeshiva University, who is also a Howard Hughes Medical Institute (HHMI) investigator, has been awarded a three-year, $4 million grant from the National Institutes of Health (NIH) to develop a novel genetic strategy for combating tuberculosis (TB). TB causes almost two million deaths each year, making it the world’s most deadly bacterial infection.
For married couples in which one partner is HIV-positive and the other is HIV-negative, antiretroviral therapy (ART) does not reduce the risk of transmitting HIV to the uninfected partner, according to a study from China in the October issue of JAIDS: Journal of Acquired Immune Deficiency Syndromes. JAIDS is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health, a leading provider of information and business intelligence for students, professionals, and institutions in medicine, nursing, allied health, pharmacy and the pharmaceutical industry.

While the U.S. has made great progress in the prevention and treatment of tuberculosis, the nation has become more susceptible to potential epidemics of multidrug-resistant tuberculosis (MDR-TB), according a study led by Johns Hopkins researchers. Computer simulations show that as TB prevalence falls, the risk for more extensive MDR-TB increases. In addition, the simulation also showed that higher detection of TB cases without proper treatment of cases also increased risk.

Fears over the influenza A virus (H1N1; sometimes referred to as swine flu) have motivated researchers to investigate the antimicrobial activity of the Aganocide® compounds against viruses.
In a recent study presented at this year’s Interscience Conference on Antimicrobial Agents and Chemotherapy (ICAAC), a team led by Dr. Dmitri Debabov, head of Cell and Microbiology, and Meghan Zuck, a Research Associate, at NovaBay Pharmaceuticals, reported the development of infected tissue models for its Aganocide® compounds.
One third of the world’s population is infected with Mycobacterium tuberculosis (MTB), which leads to tuberculosis (TB), a leading cause of death world-wide. A new discovery, led by a team of researchers from Case Western Reserve University School of Medicine, offers hope for new approaches to the prevention and treatment of TB.
Dendritic cells are the grand sentinels of the immune system, standing guard 24/7 to detect foreign invaders such as viruses and bacteria, and bring news of the invasion to other immune cells to marshal an attack. These sentinels, however, nearly always fail to respond adequately to HIV, the virus causing AIDS. Now a team of scientists at NYU Langone Medical Center has discovered a sensor in dendritic cells that recognizes HIV, spurring a more potent immune response by the sentinels to the virus. They report their findings in the September 9, 2010, issue of Nature.
Personalized post cards or phone calls can be effective in encouraging more seniors to get their annual flu shots, according to a new review of evidence.
An analysis of data from influenza cases in Wisconsin indicates individuals with 2009 H1N1 infections were younger than those with H3N2 (2007-2008), and that the risk of most serious complications was not higher in adults or children with 2009 H1N1 compared with recent seasonal strains, according to a study in the September 8 issue of JAMA.
HIV-infected children in South Africa who were exposed to the drug nevirapine at birth (used to help prevent mother-to-child HIV transmission) and then received a protease inhibitor (PI) for viral suppression achieved lower rates of viremia (virus in the blood stream) if they were switched to nevirapine, compared to children who continued on the PI-based regimen, according to a study in the September 8 issue of JAMA. PI-based therapies generally have a higher cost compared to nevirapine, which may leave some children excluded from treatment.
