High blood pressure is linked to increased risk of developing or dying from cancer (September 27, 2011) -- Raised blood pressure is linked to a higher risk of developing cancer or dying from the disease according to the findings of the largest study to date to investigate the association between the two conditions. There had been contradictory results from previous, smaller studies investigating the link between cancer and blood pressure. However, this new study, which included 289,454 men and 288,345 women, showed that higher than normal blood pressure was statistically significantly associated with a 10-20% higher risk of developing cancer in men, and a higher risk of dying from the disease in both men and women. ... > full story
Chemotherapy during pregnancy does not seem to cause developmental problems in children (September 27, 2011) -- Children born after their mothers were treated with chemotherapy during pregnancy appear to be unaffected by the experience in terms of the development of their mental processes and the normal functioning of their hearts. This is the first time that children of 18 months and older have been examined after chemotherapy during pregnancy. Researchers found that prematurity did affect these children's cognitive development significantly. ... > full story
Wanna save? Keep it simple, says new research (September 27, 2011) -- If one savings goal is a good thing, two or more should be great, right? Not really. Those who want to save are more apt to keep socking money away and more of it too, if they have just one goal in mind, shows work done in multiple countries. ... > full story
Researchers uncover gene associated with blood cancers; New genetic insights could facilitate screening for mutation (September 27, 2011) -- Researchers have identified a gene frequently mutated in myelodysplasia, one of the most common forms of blood cancer. Patients with a mutation in SF3B1 had a better overall chance of survival compared to those without the mutation, suggesting that the SF3B1 mutations drive a more benign form of myelodysplasia. It is hoped that, in the future, patients could be screened for SF3B1 mutations through a single blood test. ... > full story
Hip fracture is associated with increased short-term death rates for some older women, study finds (September 27, 2011) -- Hip fracture is associated with an increase in short-term mortality (death within one year) for women ages 65 to 79 years and healthy women ages 80 years and older, although the risk returns to previous levels after one year for women ages 70 years and older, according to a new report. ... > full story
Role of gender in workplace negotiations (September 27, 2011) -- A new study finds that while women fare worse economically than men in many distributive negotiations, including salary negotiations, women do not lack the capability or motivation to bargain effectively. Instead, women are simultaneously negotiating social approval in light of gender role expectations. ... > full story
Mice stem cells guided into myelinating cells by the trillions (September 26, 2011) -- Scientists have found a way to rapidly produce pure populations of cells that grow into the protective myelin coating on nerves in mice. Their process opens a door to research and potential treatments for multiple sclerosis, cerebral palsy and other demyelinating diseases afflicting millions of people worldwide. ... > full story
Zoledronic acid reduces the recurrence of breast cancer in post-menopausal women, study finds (September 26, 2011) -- A trial investigating the use of zoledronic acid to aid chemotherapy for breast cancer has found a significant benefit for post-menopausal women. The overall survival rate in post-menopausal women was 85 percent compared to 79 percent for women who did not receive zoledronic acid. Researchers in the multi-center AZURE trial think it could be the key for a greater understanding of the mechanisms of breast cancer recurrence. ... > full story
Many U.S. physicians believe their own patients are receiving too much care, survey shows (September 26, 2011) -- A survey of U.S. primary care physicians shows that many believe that their own patients are receiving too much medical care and many feel that malpractice reform, realignment of financial incentives and having more time with patients could reduce pressures on physicians to do more than they feel is needed, according to a new report. ... > full story
Marker for Alzheimer's disease rises during day and falls with sleep (September 26, 2011) -- A marker for Alzheimer's disease rises and falls in the spinal fluid in a daily pattern that echoes the sleep cycle, researchers have found.

Breast cancer tumor make-up changes through the course of disease (September 26, 2011) -- New research has found that breast cancer tumors change their hormonal status throughout the course of disease, whereas the decision about the most effective treatment for the patient is usually only based on one biopsy of the primary tumor. For some patients, biopsy verifications of any relapse may completely change their clinical management, according to the first sizable study to look at changes in tumors in multiple relapses in breast cancer patients. ... > full story
Compound kills highly contagious flu strain by activating antiviral protein (September 26, 2011) -- A newly tested compound destroys several viruses, including the deadly Spanish flu that killed an estimated 30 million people in the worldwide pandemic of 1918. This lead compound -- which acts by increasing the levels of a human antiviral protein -- could potentially be developed into a new drug to combat the flu, a virus that tends to mutate into strains resistant to anti-influenza drugs. ... > full story

Could targeting a virus treat a common pediatric brain tumor? (September 26, 2011) -- Medulloblastomas are the most common cancerous (malignant) brain tumors in children. Although survival rates have improved over the years, medulloblastoma remains associated with substantial mortality, and long-term survivors often suffer debilitating effects from the intensive treatments. Researchers have now identified a potential target for a more cancer-specific approach to treating medulloblastoma that they hope could improve outcome in individuals with medulloblastoma. ... > full story
Bone drug is mixed blessing for breast cancer patients (September 26, 2011) -- A drug used to protect bone may extend survival in older breast cancer patients, according to researchers. The AZURE trial has revealed that the bisphosphonate drug zoledronic acid boosts disease-free survival in postmenopausal breast cancer patients but may have an adverse effect on younger women. ... > full story
