Women who have had a miscarriage do not need to wait before trying to get pregnant again, say doctors.

A study by the University of Aberdeen of 30,000 women found that conceiving within six months offered the best chance for a healthy pregnancy.

The findings, published in the British Medical Journal, counter international guidelines that women should wait at least six months before trying again.

Women conceiving within six months of miscarriagehad the best chance of healthy pregnancy

Women who conceived within six months were less likely to have another miscarriage, termination or ectopic pregnancy, the figures showed.

Also, among those who went on to give birth, conceiving within six months was associated with reduced risk of Caesarean birth, a premature delivery or a low birthweight baby compared with those women who had conceived between six months and a year.

Around one in five pregnancies ends in miscarriage before 24 weeks, a risk that increases with age.

SYDNEY (AFP) – Mankind may be descended from apes but Australian scientists have found proof of links much closer to the sea floor, with a study revealing that sea sponges share almost 70 percent of human genes.

Genetic sequencing of sea sponges from the World Heritage-listed Great Barrier Reef showed the ancient marine animal shared many of its genes with humans, including a large number typically associated with disease and cancer.

Lead researcher Bernard Degnan, of the University of Queensland, said the findings “would shed light on a whole range of different things,” and could lay the foundation for breakthroughs in cancer and stem cell research.

“Sponges have what’s (considered) the ‘Holy Grail’ of stem cells,” Degnan told AFP.

Exploring the genetic function of sponge stem cells could provide “deep and important connections” to the genes that influenced human stem cell biology, he said.

“(It) might actually inform the way we think about our own stem cells and how we might be able to use them in future medical applications,” he said.

The study — published in the journal “Nature” this week — is the result of more than five years of research by an international team of scientists.

It required the extraction of “really pure DNA” from sponge embryos and a complex sequencing exercise, Degnan said.

A regular weight training regime may help treat rheumatoid arthritis, research suggests.

A study of 28 patients funded by Arthritis Research UK found those who pumped iron saw improvements in basic physical function, such as walking.

Researchers at Bangor and Gwynedd Hospital said such high intensity exercising could play a key role alongside drug treatment.

Rheumatoid arthritis affects people’s joints

Experts said the exercise regime would not be appropriate for all patients.

RA is mainly a disease affecting the joints, but a less well known symptom is that it also severely reduces muscle mass and strength and this occurs even among patients whose disease is well managed.

Those with the condition are often given mild home exercises to do to stop their joints stiffening and becoming painful.

Weight training

To test how effective the weight training was the researchers split the 28 participants into two groups, the Arthritis Care and Research journal reported.

One did regular weight training for 24 weeks, while the others did the less strenuous standard home exercise regimes.
