Daily Aspirin blocks bowel cancer

A daily dose of aspirin should be given to people at high risk of bowel cancer, say scientists. Two pills a day for two years reduced the incidence of bowel cancer by 63% in a group of 861 at-risk patients, a study reported in The Lancet said. Newcastle University’s Prof Sir John Burn, who led the study, said the evidence “seems overwhelmingly strong”. Other experts said the findings added to a growing body of proof that aspirin could be used in the fight on cancer. The study w...

The Future of Sex Medicine

Sooner or later every guy deals with some type of mechanical “male-function,” such as premature ejaculation (PE) or erectile dysfunction (ED). Being quick on the trigger might work great in Westerns, but it’s not such a benefit in between the sheets. Likewise, the laws of physics are a little skewed in the bedroom, where what should go up doesn’t always stay up. All this week at Good in Bed, we’re talking about male sexual health. If you’re dealing with PE or ED, you’re not alone. They’re two of...

Prolonged bottle feed increases obesity risk

Babies who are bottle-fed until the age of two are more likely to be obese when they start school, a US study suggests. Writing in the Journal of Pediatrics, researchers found that children who were still regular bottle users at 24 months were 30% more likely to be obese aged five-and-a-half. They analysed data from nearly 7,000 children across the United States. Experts say bottle-feeding can make babies consume too many calories. The research found 22% of the two-year-olds studied were using a...

Red meat links to heart disease

A chemical found in red meat helps explain why eating too much steak, mince and bacon is bad for the heart, say US scientists. A study in the journal Nature Medicine showed that carnitine in red meat was broken down by bacteria in the gut. This kicked off a chain of events that resulted in higher le...

New ‘Smart’ Nanotherapeutics Can Deliver Drugs Directly to the Pancreas

ScienceDaily (Jan. 12, 2012) — A research collaboration between the Wyss Institute for Biologically Inspired Engineering at Harvard University and Children’s Hospital Boston has developed “smart” injectable nanotherapeutics that can be programmed to selectively deliver drugs to the cells of the pancreas. Although this nanotechnology will need significant additional testing and development before being ready for clinical use, it could potentially improve treatment for Type I dia...

Oregon scientists get stem cells from cloned human embryos

Posted on by

A team of researchers said Wednesday that it had produced embryonic stem cells — a possible source of disease-fighting spare parts — from a cloned human embryo. Scientists at the Oregon Health and Science University accomplished in humans what has been done over the past 15 years in sheep, mice, cattle and several other species. The achievement is likely to, at least temporarily, reawaken worries about “reproductive cloning” — the production of one-parent duplicate humans. But few Read more

A chemical found in red meat helps explain why eating too much steak, mince and bacon is bad for the heart, say US scientists. A study in the journal Nature Medicine showed that carnitine in red meat was broken down by bacteria in the gut. This kicked off a chain of events that resulted in higher levels of cholesterol and an increased risk of heart disease. Dieticians warned there may be a risk to people taking carnitine supplements. There has been a wealth of studies suggesting that Read more

Processed meat links to early death

Sausages, ham, bacon and other processed meats appear to increase the risk of dying young, a study of half a million people across Europe suggests. It concluded diets high in processed meats were linked to cardiovascular disease, cancer and early deaths. The researchers, writing in the journal BMC Medicine, said salt and chemicals used to preserve the meat may damage health. The British Heart Foundation suggested opting for leaner cuts of meat. The study followed people from 10 European Read more

Volunteering good for the heart

OTTAWA, Feb 27 – Volunteer work has long been touted as good for the soul, but the practice is also good for your heart, according to a study out Monday in the journal JAMA Pediatrics. Researchers at the University of British Columbia in Vancouver wanted to find out how volunteering might impact one’s physical condition, and discovered that it improves cardiovascular health, said study author Hannah Schreier. And “the volunteers who reported the greatest increases in empathy, altruistic Read more

Bad sleep ‘dramatically’ alters body

A run of poor sleep can have a dramatic effect on the internal workings of the human body, say UK researchers. The activity of hundreds of genes was altered when people's sleep was cut to less than six hours a day for a week. Writing in the journal Proceedings of the National Academy of Sciences, the researchers said the results helped explain how poor sleep damaged health. Heart disease, diabetes, obesity and poor brain function have all been linked to substandard sleep. What missing Read more

Vegetarians cut heart risk by 32%

Ditching meat and fish in favour of a vegetarian diet can have a dramatic effect on the health of your heart, research suggests. A study of 44,500 people in England and Scotland showed vegetarians were 32% less likely to die or need hospital treatment as a result of heart disease. Differences in cholesterol levels, blood pressure and body weight are thought to be behind the health boost. The findings were published in the American Journal of Clinical Nutrition Heart disease is a major blight Read more

DNA map offers hope on cancer treatments

All patients will soon have their tumour’s DNA, its genetic code, sequenced, enabling doctors to ensure they give exactly the right drugs to keep the disease at bay. Doctors hope it will be an important step towards transforming some types of cancer into a chronic rather than fatal disease. The technique could enable terminally ill patients, who can currently expect to live only months, to carry on for a decade or more in relatively good health, according to specialists at Read more

This article was written by KEN MURRAY, MD Years ago, Charlie, a highly respected orthopedist and a mentor of mine, found a lump in his stomach. He had a surgeon explore the area, and the diagnosis was pancreatic cancer. This surgeon was one of the best in the country. He had even invented a new procedure for this exact cancer that could triple a patient’s five-year-survival odds—from 5 percent to 15 percent—albeit with a poor quality of life. Charlie was uninterested. He went home the Read more

Doctors have warned of a "lack of knowledge" about the dangers of mixing some medications with grapefruit. The fruit can cause overdoses of some drugs by stopping the medicines being broken down in the intestines and the liver. The researchers who first identified the link said the number of drugs that became dangerous with grapefruit was increasing rapidly. They were writing in the Canadian Medical Association Journal. The team at the Lawson Health Research Institute in Canada said the Read more

Emotional distress, also known as psychological distress, can increase the risk of death in the general population. Anecdotal evidence has shown that distress leads to a myriad of health disorders. [Psychol Med 1995;25(5):1073-86, Ann Epidemiol 2004;14:467-72] Emotional distress, a term referring to the signs and symptoms of depression and anxiety, has been linked to an increased risk of premature mortality, cardiovascular disease, susceptibility to infection and, potentially, all cancers.
