Drinking alcohol can not only ease the symptoms of rheumatoid arthritis it appears to reduce disease severity too, research suggests.
Scientists at the University of Sheffield asked two groups of patients with and without the disease to provide details of their drinking habits.
They found that patients who had drunk alcohol most frequently experienced less joint pain and swelling.
Experts say this should not be taken as a green light for drinking more.
Exercise scientists say they have stumbled on an amazing discovery. Athletes can improve their performance in intense bouts of exercise, lasting an hour or so, if they merely rinse their mouths with a carbohydrate solution. They don’t even have to swallow it.
And the scientists think they have figured out why it works. It appears that the brain can sense carbohydrates in the mouth, even tasteless ones.
“You can get an advantage from tricking your brain,” said a discoverer of the effect, Matt Bridge, a senior lecturer in coaching and sports science at the University of Birmingham in England. “Your brain tells your body, ‘Carbohydrates are on the way.’ ” And with that message, muscles and nerves are prompted to work harder and longer.”

UK researchers say they have uncovered why women who often wear high heels can find it painful to wear flat shoes.
In the final part of the study, they found that the high-heel wearers’ tendons were much thicker and stiffer than in those who stuck to flat shoes.
This causes discomfort when walking on flat feet because the tendon cannot stretch sufficiently, Professor Narici said.
Yet he does not think women need to give up their high heels.
The advice we would give is not to wear heels or flat shoes all the time but to wear a variety of heel heights”
“Fashion is intended to be uncomfortable and none of the women in the study planned to give up their high heels,” he said.
“We want to give practical advice and I would recommend just doing a few stretching exercises to counteract some of these changes.”
Sammy Margo, physiotherapist and spokesperson for the Chartered Society of Physiotherapy, said the study backed what they suspected.
“The advice we would give is not to wear heels or flat shoes all the time but to wear a variety of heel heights to get the calf muscles working through the greatest range of movement. . . .”

A new study finds that from 1990 to 2007, nearly a million Americans wound up in emergency rooms with weight-training injuries, and that annual injuries increased more than 48 percent in that period.
Women were more likely to injure their feet and legs, while men’s injuries were more common in the trunk and hands; men had more sprains and strains, and women had more fractures.
Overexertion, muscle pulls and loss of balance accounted for about 14 percent of emergency room visits. More than 90 percent of the injuries occurred while using free weights rather than weight machines.

MADRID (AP) — Cristiano Ronaldo has become a father, his website said Sunday, although the mother’s identity is being kept a secret.
The Real Madrid winger and Portugal captain said “it is with great joy and emotion that I inform I have recently become father to a baby boy. As agreed with the baby’s mother, who prefers to have her identity kept confidential, my son will be under my exclusive guardianship.”
No date for the birth was given.
The 25-year-old Ronaldo is not married, however since his signing by Madrid was announced he has often been photographed in the company of women.
“I request everyone to fully respect my right to privacy (and that of the child) at least on issues as personal as these are,” he said.

(HealthDay News) — You and your athletic child should keep some safety rules in mind before the game starts.
The Nemours Foundation offers these suggestions to help keep kids safe:
PARIS (AFP) – – Acupuncture eases pain in the limbs because it releases a natural molecule called adenosine, neuroscientists in the United States reported on Sunday.
The mechanism was discovered through experiments in lab mice, which were given an injection of an inflammation-inducing chemical in their right paw.
The researchers inserted fine needles below the midline of the mice’s knee, at a well-known acupuncture location called the Zusanli point.
They rotated the needle gently every five minutes for 30 minutes, mimicking a standard acupuncture treatment.
During and just after this operation, levels of adenosine in the tissues surrounding the needle surged 24-fold. The mouse’s discomfort — measurable by the rodents’ response time to touch and heat — was reduced by two-thirds, they found.
The same test was carried out on mice that had been genetically engineered to lack adenosine. The acupuncture failed to have any effect, and the mice reacted in discomfort, as before.
The team then experimented with an adenosine booster. They gave mice a leukaemia drug called deoxycoformycin, which makes it harder for tissues to remove adenosine.
As a result, levels of adenosine accumulated in the muscles, nearly tripling the duration of the acupuncture’s effectiveness.
“Acupuncture has been a mainstay of medical treatment in certain parts of the world for 4,000 years, but because it has not been understood completely, many people have remained skeptical,” said Maiken Nedergaard of the University of Rochester Medical Center in New York, who headed the research.
Previous work has focussed on acupuncture’s effectiveness on the central nervous system — the trunk of nerves in the spinal cord and brain — rather than the peripheral nervous system.
In the central nervous system, acupuncture creates signals that cause the brain to produce powerful anti-pain chemicals called endorphins.
