QuitWinLive – The Great American Smokeout

November 15, 2007 | by

quit-smokingToday, the American Cancer Society (ACS) celebrates the Great American Smokeout, an annual event in the U.S. to encourage Americans to quit smoking. According to the U.S. Centers for Disease Control and Prevention (CDC), in 2006 one in five U.S. adults smoked [1]. The Great American Smokeout challenges those people to smoke less or quit smoking for the day. The event also raises awareness of the many effective ways to quit for good.

The ACS has just wrapped up their first ever video contest on YouTube, where they asked people to create videos – one minute or less – to discourage smoking. You can check out the contest winners at the American Cancer Society.

Common Therapy for Prostate Cancer May Promote Metastasis

November 14, 2007 | by

A study published in the journal Cancer Research last month suggests that the principle treatment for advanced prostate cancer may actually encourage prostate cancer cells to metastasize [1]. Researchers at The Johns Hopkins University School of Medicine focused on a gene called Nestin, which encodes an intermediate filament protein. Intermediate filaments are cytoskeletal or scaffolding structures found in cells that, in addition to maintaining cell shape, control a variety of cellular processes including proliferation, migration and survival [2]. Nestin gene expression also distinguishes stem cells from differentiated cells and has been shown to be activated in pediatric brain tumors and rhabdomyosarcomas (cancers that develop from skeletal muscle), central nervous system tumors and gastrointestinal stromal tumors [3-6].

Merck HIV Vaccine Increases Risk of HIV Infection

November 10, 2007 | by

Merck has been testing a candidate HIV vaccine in two large phase II clinical trials; the STEP study in North and South America, the Caribbean and Australia, and a parallel study called Phambili in South Africa.

STEP was a multi-center, randomized, double-blind, placebo-controlled phase II test-of-concept clinical trial. Started in December 2004, enrollment in the study was completed by March 2007 and more than 2,500 participants had received all three doses of vaccine or placebo. STEP was evaluating two primary efficacy endpoints:hiv virus

  • Whether the vaccine prevented HIV infection in subjects who were HIV negative at the beginning of the study.
  • Whether the vaccine lowered the amount of virus in subjects who became HIV infected during the course of the study.

However, last month the drug trial was halted because the vaccine appeared to be increasing the risk of HIV infection among study participants. The South African study Phambili, which began in 2007 using the same vaccine has been halted [1].

Elsevier’s Approaches to Public Access of Biomedical and Cancer Research

Elsevier, a leading publisher of over 400 medical and scientific journals serving more than 30 million scientists, students and health and information professionals worldwide, has initiated a beta test program called Patient Research. The program gives patients, family members and caregivers access to medical articles to help them understand their health issues.

The Flu, Your Health and the Importance of Vaccination

November 1, 2007 | by

The flu season runs from November to April, with most cases occurring between late December and early March. About 10% to 20% of people get the flu every winter [1]. In children, the odds are even worse, with up to 40% of children becoming clinically ill due to the influenza virus.

The best way to prevent seasonal flu is to get a flu vaccination. Hospitalization and death from flu complications pose real risks. Every year, on average, more than 200,000 people are hospitalized from flu complications and approximately 36,000 people die from the flu [2].

Additionally, immunizing children against influenza is perhaps the best method to reduce the occurrence of the flu in the community. If children receive the flu shot but the rest of the family abstains, the influenza attack rate drops by 40%; if parents also get the flu shot, the influenza attack rate drops by 80% [3].
