Removing Old Cells Could Extend Human Life

The old adage “Out with the old and in with the new” could help prevent age-related diseases if applied to certain cells, new research on mice suggests.

By removing the body’s worn-out cells, called senescent cells, several times during the lifetime of aging-accelerated mice, researchers were able to spare the mice of cataracts, aging skin and muscle loss.

“We started treating animals when they were really young, before they started to establish these senescent cells,” study researcher Darren Baker, of the Mayo Clinic College of Medicine in Minnesota, told LiveScience. “As a cell became senescent we would remove it; we saw a really profound effect.” [Read more...]

Surgeons Warn Over Limiting Obesity Operations

The NHS would regret the cost of limiting treatment for obesity, a group of surgeons said today.

According to a report, patients with severe obesity face premature death, disease and disability which could be prevented or eliminated by surgery.

Research by the National Bariatric Surgery Registry (NBSR) found obesity surgery treats a range of life-threatening diseases, including achieving an 86% reduction in the number of patients with type 2 diabetes.

Surgeons suggest the figures demonstrate the cost-effectiveness of early weight-loss treatment.

Data from more than 8,700 operations carried out in the NHS and private sector showed around two thirds of severely obese patients have three or more associated diseases by the time they reach surgery. [Read more...]

‘Heart Boost’ For Moderate Drinkers

Individuals who drink alcohol in moderation (about one drink a day or less) are less likely to develop heart disease than those who drink no alcohol at all, according to a study.

Those who drink a small amount are 14-25% less likely to develop the condition than non-drinkers, the research led by Professor William Ghali from the University of Calgary in Canada found.

A paper led by Dr Susan Brien, also from the University of Calgary, found that moderate consumption of alcohol (up to one drink or 15g alcohol per day for women and up to two drinks or 30g alcohol per day for men) is good for health.

The researchers say that moderate amounts of alcohol significantly increase the levels of ‘good’ cholesterol circulating in the body and this has a protective effect against heart disease. [Read more...]

Six Months Of Breastfeeding Alone Could Harm Babies, Scientists Now Say

To the outrage of breastfeeding campaigners and probably the utter confusion of most women with small babies, scientists today advocate rewriting the rulebook to drop the current guidance that says mothers should breastfeed exclusively for the first six months of their child’s life.

It was 2001 when the World Health Organisation announced that exclusive breastfeeding for six months was best for babies. In 2003 the then Labour minister Hazel Blears adopted the recommendation for the UK.

But today, in the British Medical Journal, doctors from several leading child health institutes say the evidence for the WHO guidance was never there – and that failing to start weaning babies on to solids before six months could be harmful.

Mary Fewtrell, from the childhood nutrition research centre at the University College London Institute of Child Health, said probably no babies had been harmed, as few mothers in the UK manage to stick to six [Read more...]

Hidden Heart Disease

Scott Cote, a 41-year-old software engineer, lost weight, cut sodium and began exercising to control his blood pressure, all as a result of new attention being given to prehypertension. It’s a precursor to hypertension, or high blood pressure. And it has its own risks of stroke and heart disease.

About a third of all U.S. adults have prehypertension, a borderline zone with its own risk of stroke, heart disease and likelihood of worsening into full hypertension. Laura Landro has details and offers five ways to lower your blood pressure.

Mr. Cote, a participant in a study at Massachusetts General Hospital through his employer, EMC Corp., monitors his blood pressure at home and uploads the readings to a website, where a “virtual coach” gives him personalized tips, reminders and feedback to help him stay on track. His new lifestyle, which he adopted after his doctor gave him the prehypertension diagnosis in 2008, is a big change from his old sedentary habits. [Read more...]

Women Who Get Dental Care Have Lower Risk Of Heart Disease

A new study led by a University of California, Berkeley, researcher could give women a little extra motivation to visit their dentist more regularly. The study suggests that women who get dental care reduce their risk of heart attacks, stroke and other cardiovascular problems by at least one-third.

The analysis, which used data from nearly 7,000 people ages 44-88 enrolled in the Health and Retirement Study, did not find a similar benefit for men.

Published online Sept. 29 in the journal Health Economics, the study compared people who went to the dentist during the previous two years with those who did not. [Read more...]

Study Finds High Rate Of C-Sections After Pelvic Fractures

In research led by a Saint Louis University surgeon, investigators found that women who give birth after suffering pelvic fractures receive C-sections at more than double normal rates despite the fact that vaginal delivery after such injuries is possible. In addition, women reported lingering, yet often treatable, symptoms following their pelvic fracture injuries, from urinary complications to post-traumatic stress disorder.

The study, published in Clinical Orthopaedics and Related Research, retrospectively reviewed the cases of 71 women who had suffered pelvic fractures, 26 of whom subsequently had children. Of those 26 women, 10 delivered vaginally and 16 gave birth by C-section. [Read more...]
