Hormone Therapy Risks Outweigh Benefits

Posted: Published on May 30th, 2012

An elderly woman walks in San Jose on May 12. (RODRIGO ARANGUA/AFP/GettyImages) Women past menopause should not take hormone replacement therapy (HRT) due to increased risk of disease, says a recent statement by a panel of preventive medicine experts. The U.S. Preventive Services Task Force (USPSTF) released a draft recommendation statement May 29 that found the potential harm of HRT, and its use of estrogen and progestin, greater than the potential benefit. The group suggests that HRT not only fails to protect against heart disease, it actually increases the risk of that and other ills. The task force recommends against the use of combined estrogen and progestin for the prevention of chronic conditions in postmenopausal women, according to the draft statement. Osteoporosis, a disease that causes loss of bone density and bone tissue, can be a debilitating, painful condition that impacts menopausal women over 50. Hormones were once touted as a fountain of youth, meant to keep bones strong, skin supple, brains smart, and hearts healthy. Menopausal women over 50 have a lower risk of hip fractures and other fractures if they take hormones. The USPSTF found convincing evidence that estrogen and progestin therapy is of moderate benefit in reducing … Continue reading

Breast stem cell research: Receptor teamwork required and a new pathway may be involved

Posted: Published on May 30th, 2012

Madison, Wisconsin - Breast-cancer researchers at the University of Wisconsin-Madison have found that two related receptors in a robust signaling pathway must work together as a team to maintain normal activity in mammary stem cells. Mammary stem cells produce various kinds of breast cell types. They may also drive the development and growth of malignant breast tumors. Published recently in the Journal of Biological Chemistry, the research also suggests that a new signaling pathway may be involved, a development that eventually could take cancer-drug manufacturers in a new direction. "We wanted to know if we could use this knowledge to inform us about what might be the transition that occurs to start tumor growth and maintain it," says senior author Dr. Caroline Alexander, professor of oncology at the McArdle Laboratory for Cancer Research at the School of Medicine and Public Health. The paper describes new information about the Wnt signaling pathway. Wnt signaling underlies numerous activities in normal development, but when the system is unregulated, cancer often occurs.

New Personalized Medicine for ALK-positive Advanced or Metastatic Non-small Cell Lung Cancer

Posted: Published on May 30th, 2012

XALKORI NOW AVAILABLE IN CANADA KIRKLAND, QC, May 30, 2012 /CNW/ - Pfizer Canada is pleased to announce that XALKORI (crizotinib) is now available in Canada. Recently approved with conditions by Health Canada, XALKORI is an oral monotherapy for patients with anaplastic lymphoma kinase (ALK)-positive advanced or metastatic non-small cell lung cancer (NSCLC).1 XALKORI is Pfizer Canada's first example of personalized medicine for people with ALK-positive non-small cell lung cancer. Lung cancer has been one of the most difficult cancers to treat because symptoms typically do not appear until the disease has already reached an advanced stage.2 Even when symptoms appear, they are often mistaken for other health problems further delaying patients from receiving the care they may need.3 As a percentage of all cancer deaths, lung cancer kills more Canadians (27%) than breast cancer (7%), colorectal cancer (12%) and prostate cancer (5%).4 Approximately 70 Canadians are diagnosed with lung cancer every day and 55 die of lung cancer every day.5 "Little has changed in the way lung cancer has been treated in the past 40 years6," says Dr. Normand Blais, Hemato-Oncologist at CHUM - Hpital Notre-Dame in Montreal. "Previously lung cancer was considered a single disease. With the discovery … Continue reading

A UC Irvine stem cell researcher won a $4.8-million grant to fund research toward a treatment for multiple sclerosis. The California Institute for Regenerative Medicine awarded immunologist Thomas Lane, of the campus' Sue and Bill Gross Stem Cell Research Center, an Early Transitional Award last week to create a new line of neural stem cells to treat multiple sclerosis, according to a UCI press release. "I am delighted that [the California Institute] has chosen to support our efforts to advance a novel stem cell-based therapy for multiple sclerosis," Peter Donovan, director of the research center, said in the release. Lane is collaborating with Jeanne Loring, director of the Center for Regenerative Medicine at the Scripps Research Institute in La Jolla, and Claude Bernard, a multiple sclerosis researcher at Monash University in Australia. The research project "really embodies what [the California Institute] is all about, which is bringing science together to treat horrible diseases like multiple sclerosis," said Lane, who is a professor of molecular biology and biochemistry. Multiple sclerosis is a central nervous system disease that causes inflammation and a loss of myelin, a fatty tissue that insulates and protects nerve cells.

Toni Clarke BOSTON Globe and Mail Update Published Friday, May. 18, 2012 12:38PM EDT Last updated Friday, May. 18, 2012 12:56PM EDT Osiris Therapeutics Inc. OSIR-Q said on Thursday that Canadian health regulators have approved its treatment for acute graft-versus host disease in children, making it the first stem cell drug to be approved for a systemic disease anywhere in the world. Osiris shares rose 14 per cent to $6.00 in extended trading after the news was announced. Graft versus host disease (GvHD) is a potentially deadly complication from a bone marrow transplant, when newly implanted cells attack the patient's body. Symptoms range from abdominal pain and skin rash to hair loss, hepatitis, lung and digestive tract disorders, jaundice and vomiting. The disease kills up to 80 per cent of children affected, Osiris said. To date there have been no approved treatments for the disease. Canadian authorities approved the therapy, Prochymal, for use in children who have failed to respond to steroids. Prochymal was approved with the condition that Osiris carry out further testing after it reaches the market. C. Randal Mills, the company's chief executive, said in an interview that could take three to four years. Some investment analysts … Continue reading

Ottawa’s latest brain gain brings promising new stem-cell therapy

Posted: Published on May 30th, 2012

OTTAWA Dr. Bernard Thebaud believes he can use the healing juices from stem cells the much ballyhooed future of modern medicine to rejuvenate the lungs of premature babies. The renowned neonatologist and scientist has proven his treatment works in rats in Edmonton, and in a baboon in San Antonio, Texas. Next, he will design clinical trials to test his pioneering therapy in babies in Ottawa. Dr. Thebaud is the latest recruit to the Sprott Centre for Stem Cell Research at the Ottawa Hospital Research Institute. Lured here from the University of Alberta, Dr. Thebaud hopes that within five years he can take his research from bench to bedside by launching the first clinical trials in newborns. He believes his therapy, derived from stem cells isolated from discarded umbilical cords, can help people suffering from other lung diseases, such as asthma and fibrosis. In an interview, the 47-year-old, who is originally from France, said Ottawa was the only city where he could do this research. To get this work into patients, I need to be around a critical mass of top stem cell biologists, he said. I dont want to be too clich, but if you are in the computer business … Continue reading
