Cancer Pill Gleevec Keeps Patients Alive and Well for a Decade

The once-a-day pill turned chronic myelogenous leukemia, or CML, from a certain death sentence into a manageable disease. Now data shows it's helped 83 percent of patients live 10 years or longer...."It's the first targeted personalized medicine that had ever been used. It was also the most successful," ...Gleevec is targeted to a mutation specific to CML...."It's a 10-year survival of 83 percent, which is extraordinary," Silver said. "It has led to what we call biologic cures." Patients still have leukemia, but it's not affecting their blood cell counts.

Dizzy spells in middle age may be a warning sign of dementia 20 years before symptoms appear

Scientists think sudden drops in blood pressure - often signaled by dizziness when standing up - could cause lasting damage to the brain that raises the risk of dementia. A study of 11,000 middle-aged people found that those who suffered this problem, known as orthostatic hypotension, were 40 per cent more likely to develop dementia later in life.

Study leader Dr Andreea Rawlings, from the Johns Hopkins Bloomberg School of Public Health in the US, said: 'Even though these episodes are fleeting, they may have impacts that are long lasting. 'We found that those people who suffered from orthostatic hypotension in middle age were 40 per cent more likely to develop dementia than those who did not. 'It's a significant finding and we need to better understand just what is happening.'

Scientists Have Created an Artificial Retina Implant That Could Restore Vision to Millions

Scientists have developed a retinal implant that can restore lost vision in rats, and are planning to trial the procedure in humans later this year.  The implant, which converts light into an electrical signal that stimulates retinal neurons, could give hope to millions who experience retinal degeneration – including retinitis pigmentosa – in which photoreceptor cells in the eye begin to break down, leading to blindness.


For the Blind, an Actual-Reality Headset  Not just Star Trek fiction, a new visor from eSight is a lightweight, high-contrast vision system for legally blind people.

Artist Yvonne Felix recalls the first time she saw “Starry Night” with her eSight visor on, it made her cry. “I saw every little stroke. When I saw the color mixtures and how thick the paint was, it was the most overwhelming moment of my life,” she says. “I thought that never in my life would I be able to see something so beautiful.”

Secondhand smoke isn’t as bad as we thought. The relevant question, however, should not be merely whether there are any dangers from secondhand smoke but also how big they are.

If the alarmist claims made by anti-smoking groups were true, we’d be justified in avoiding secondhand smoke as if it were the plague. But we know now that those claims were exaggerated, so it’s worth asking whether contemporary bans have gone too far.... Now that’s not nothing, but other recent research may be even more surprising. “No clear link between passive smoking and lung cancer,” read a 2013 headline in the Journal of the National Cancer Institute, hardly a pro-tobacco publication. That was a report on a cohort study tracking 76,000 women that failed to detect a link between the disease and secondhand smoke. The finding comports with existing literature suggesting that the effect is borderline and concentrated on long-term, high levels of exposure.

Cannabis boosts risk of stroke and heart attack, independent of tobacco, new study finds

Data taken from more than 1,000 US hospitals found that people who used the drug had a 26 per cent higher chance of suffering a stroke than those who did not, and a 10 per cent higher chance of having a heart attack....They indicate there is something intrinsic about cannabis which can damage the proper functioning of the human heart.  The research was published Wednesday at a meeting of the American College of Cardiology in Washington DC.

Bad news for bald men: Hair loss drugs cause erectile dysfunction that lasts for years

Those taking a popular growth stimulant were left impotent for an average of four years after finishing the medication, a study found.  Sufferers were left unable to maintain an erection despite being given Viagra to try and solve their problem.  Experts now say that taking finasteride is a bigger risk factor for the condition than diabetes, high blood pressure and smoking.  The drug, sold as Propecia, lowers prostate specific antigen levels and is used for treating male-pattern hair loss.

Researchers from Northwestern University Feinberg School of Medicine assessed the effects of the hair growth stimulant. Of the 11,909 men who were studied, 1.4 per cent went on to develop persistent erectile dysfunction. This continued for an average of 1,348 days.  But the researchers found men under the age of 42 who used either drug for seven months had a 4.9-fold higher risk.

This comes after Turkish scientists last week found blood type could influence a man's performance under the sheets. Those with blood types A, B or AB are up to four times more likely to suffer from impotence than men who have blood type O.
