The benefits of marijuana in tempering or reversing the effects of Alzheimer's disease have been challenged in a new study by researchers at the University of British Columbia and Vancouver Coastal Health Research Institute.

Increased sugar intake may stimulate tumor growth through effects of insulin.Pancreatic cancer rates increased nearly twofold over the past several decades.Drinking two or more soft drinks a week led to an 87 percent increased risk.

A new study suggests that beer is a significant source of dietary silicon, a key ingredient for increasing bone mineral density. Details of this study are available in the February issue of the Journal of the Science of Food and Agriculture, published by Wiley-Blackwell on behalf of the Society of Chemical Industry.

Women with medium or low levels of income are more susceptible to anxiety and depression after ductal carcinoma in situ diagnosis.

Increased Medicare payments to physicians for outpatient surgeries for bladder cancer have led to a dramatic rise in the number of these procedures being performed and an overall increase in cost to the health care system.

A new national study suggests that preschool-aged children are likely to have a lower risk for obesity if they regularly engage in one or more of three specific household routines: eating dinner as a family, getting adequate sleep and limiting their weekday television viewing time. The study showed that 4-year-olds living in homes with all three routines had an almost 40 percent lower prevalence of obesity than did children living in homes that practiced none of these routines.

A parent's existing health habits or behaviors, like cigarette smoking, may influence the likelihood that they will have their daughters vaccinated against HPV.

Treatment of endometrial cancer has not advanced significantly in 30 years and there are no screening tests to promote early detection. Researchers at the University of Texas Southwestern Medical Center and Harvard Medical School developed a new approach to specifically target genetic changes to the endometrial cells in mice. Using this new technique, they show that loss of an emerging tumor suppressor causes abnormal growth and widespread malignancy of cells lining the uterus.

Mice with a genetic change that causes progressive hearing loss in children, also have hearing loss because sound waves are not processed properly. The ear's attempts to compensate for hearing loss may, ironically, cause further damage leading to complete hearing loss. These mice will allow detailed research into many forms of deafness, and bring closer the prospects of therapies to slow or halt hearing loss in both children and adults.

Less than a quarter of one percent of women took tamoxifen in 2000 and 2005 to prevent breast cancer.Further research is recommended to explore explanations for the drug's low use.

Advanced maternal age is linked to a significantly elevated risk of having a child with autism, regardless of the father's age, according to an exhaustive study of all births in California during the 1990s by UC Davis Health System researchers.

A new tool may help standardize the use of computed tomography (CT scans) in children with minor head injury and help reduce the number of scans, according to a new study in CMAJ.

Governments are under increasing pressure to provide access to expensive new drugs. Canadian patients who want access to drugs that are not publicly insured are seeking to pay for these drugs within public hospitals, states an article in CMAJ.

Poor or declining hand-grip strength in the oldest old is associated with poor survival and may be used as a tool to assess mortality, found an article in CMAJ. The fastest growing segment of the elderly population is the group older than 85 years, classified as the oldest old.
