New findings from University of Utah School of Medicine researchers show that the retrovirus called XMRV is not present in the blood of patients who have chronic fatigue syndrome (CFS). These findings contradict a widely reported 2009 Science study that linked CFS to XMRV.
Getting vaccinated against the flu lowers kidney transplant recipients’ risk of organ loss and death, according to a study appearing in an upcoming issue of the Clinical Journal of the American Society Nephrology (CJASN). The results suggest that concerns about the safety of the influenza vaccine in transplant recipients are unwarranted.
Roughly one out of every 24 patients undergoing surgery acquires a surgical site infection. With 40 million operations performed in the U.S. each year, between 800,000 and 2 million individuals contract these infections annually. An innovative new pilot project being launched by Sherry Lansing, a regent of the University of California, and her husband, Academy Award–winning film director William Friedkin, provides hope for the future in helping hospitals address such infections.
A rebound of the Hepatitis B virus is common in patients receiving nucleoside analogs for chronic hepatitis B. But nearly 40% of the rebounds were not related to antiviral drug resistance.
NIST researchers studied different methods for collecting, extracting and quantifying microbial spores from indoor surfaces to estimate parameters that should be considered in the development of a standard biological sampling protocol.
Despite public health campaigns that explain ways to stop sleeping sickness infection, successful eradication has remained out of reach. That's partly because epidemiologists can't predict where cases will emerge next. Now, efforts by Michigan State University geographer Joseph Messina to map future tsetse fly distribution may help solve this sleeping sickness "mystery."
Patients infected with cancer-causing HPV may someday have an alternative to surgical and harsh chemical treatments, thanks to research being done at Tufts University School of Medicine. In a study published online in The FASEB Journal, researchers report on the development of a protein-based inhibitor that could provide a topical treatment for HPV.

New research on mice has shown that pulmonary administration of granulocyte macrophage-colony stimulating factor (GM-CSF) significantly reduces flu symptoms and prevents death after a lethal dose influenza virus. While GM-SCF therapy for humans as a flu prophylaxis or treatment may be years away, the study results were striking: All of the mice treated with GM-SCF survived after being infected with the influenza virus, whereas untreated mice all died from the same infection.

The meaning of the standard fecal coliform test used to monitor water quality has been called into question by a new study that identified sources of Escherichia coli bacteria that might not indicate an environmental hazard.
Fungal infections are a major health problem for people whose immune systems are compromised because of genetic deficiencies, AIDS, or cancer and associated medical treatments like chemotherapy. In those people a deficient immune response can permit fungi to take hold in the body and produce severe infection. In addition, exposure to environmental fungi can exacerbate asthmatic reactions. Dr. Amariliz Rivera and colleagues report new insights into the body's reaction to inhaled fungi.

Re-activation and growth of HSV1 infections contribute to cognitive decline associated with Alzheimer’s disease.
Researchers with the International Agency for Research on Cancer (IARC) have found that people with lung cancer were significantly more likely to have several high-risk forms of human papillomavirus (HPV) antibodies compared to those who did not have lung cancer. These results, which were presented at the AACR 102nd Annual Meeting 2011, held April 2-6, indicate that HPV antibodies are substantially increased in people with lung cancer.
