Novel H1N1 (referred to as “swine flu” early on) is a new influenza virus causing illness in people. This new virus was first detected in people in the United States in April 2009. Other countries, including Mexico and Canada, have reported people sick with this new virus. This virus is spreading from person-to-person, probably in much the same way that regular seasonal influenza viruses spread.
A Mayo Clinic study of a drug that has shown promise in treating sarcoma, lung and brain cancers, demonstrates that the drug may also be effective in treating breast cancer, in particular the spread of breast cancer.
A new Mayo Clinic study found a nationwide decrease in the need for liver transplant in patients with hepatitis B, which coincides with the increasingly widespread use of oral antiviral medications to slow disease progression. The study will be presented this week at the annual meeting of the American Association for the Study of Liver Diseases in Boston.
A comparison of illness and death rates for 13 vaccine-preventable diseases in the U.S., before and after use of the vaccine, indicates there have been significant decreases in the number of cases, hospitalizations and deaths for each of the diseases examined, according to a study in the November 14 issue of JAMA.
When a host cell is infected with HIV, the virus brings its own genetic material into the host cell. This cell then replicates, reads the viral RNA, and uses it as a blueprint to produce more viral proteins. Complete viruses are then released to attack the next cells.
Experts don’t dispute the important role that diet and activity play in maintaining a healthy weight. But can poor eating habits and a less active lifestyle fully explain the prevalence of obesity in the United States today? That question has led some researchers to ask whether there might be other causes for this serious problem. In the October issue of Mayo Clinic Proceedings, researcher Richard Atkinson, M.D., asserts that there is a growing body of evidence demonstrating that viruses may play a role in causing obesity in humans.
Despite the availability of life-saving antiretroviral treatment, people infected with HIV (human immunodeficiency virus) continue to die and suffer from complications of AIDS, mainly due to delayed diagnosis and initiation of treatment. A researcher at the Albert Einstein College of Medicine of Yeshiva University and colleagues at Yale University have shed light on why this problem persists. They report their findings in the November issue of the journal Medical Care.
Patients with the hepatitis C virus (HCV) have a risk of frequent recurrence and deterioration of liver function, even after curative treatment for the primary hepatocellular carcinoma (HCC). This unfavorable prognosis is associated with a sustained HCV infection. Thus, both the prevention of HCC recurrence and the preservation of liver function are high priorities when trying to improve the prognosis of patients with HCV-related HCC. Antiviral therapy for chronic hepatitis C (HCV) after treatment for primary HCC is the essential factor required for an improved prognosis.
Researchers at the University of Leeds have made a breakthrough in understanding a virus which poses one of the greatest global disease threats to wild carnivores including lions, African wild dogs and several types of seal.
An anal fissure is a cut or tear occurring in the anus (the opening through which stool passes out of the body) that extends upwards into the anal canal. Patients may try to avoid defecation because of the pain. The pain may also affect urination causing dysuria, frequent urination, or the inability to urinate. Bleeding in small amounts, itching (pruritus ani), and a malodorous discharge may occur due to the discharge of pus from the fissure.
