Lyme disease: Older white women ‘at highest risk’

Health
Older women are at most risk of contracting Lyme disease, a study suggests - and parts of southern and south-west England are "hotspots".There are around 3,000 cases of the disease - a bacterial infection carried by ticks - each year in the UK. But experts say everyone should become aware of the characteristic bulls-eye rash and flu-like symptoms.More than 2,300 hospital patients with the condition were analysed between 1998 and 2015.Of all the cases identified in the BMC Public Health study, 60% were women or girls.On the upNew cases peaked between six and 10 years old and between 61 and 65.Almost all the 1,877 patients who gave information were white.Cases overall have gone up - from 0.08 per 100,000 in 1998 to 0.53 per 100,000...
Unusual structures in bacteria suggest photosynthesis older than thought

Unusual structures in bacteria suggest photosynthesis older than thought

Science
July 25 (UPI) -- Scientists have discovered unusual structures in rare bacteria that resemble the cellular components that power photosynthesis. The discovery, described this week in the journal Trends in Plant Science, suggests photosynthesis has ancient evolutionary roots. Plants, algae and some bacteria perform what's known as oxygenic photosynthesis, splitting water into oxygen and hydrogen to power the process that turns solar energy into food. Some bacteria use anoxygenic photosynthesis, splitting other molecules besides water. Anoxygenic photosynthesis has long been assumed to be the more primitive of the two. Anoxygenic photosynthesis, most scientists agree, emerged 3.5 billion years ago. Oxygenic photosynthesis came a billion years later. But analysis of rare, ancient bacteria r...
Surgery helps older patients with meniscus tear better than observation, study says

Surgery helps older patients with meniscus tear better than observation, study says

Health
July 11 (UPI) -- Meniscal root tears, often associated with younger athletes, also commonly strike older people with degenerative knee problems, a new study says. Now, a new inside arthroscopic repair technique has proven to help repair these injuries in older adults, avoiding the need for more complicated surgeries, according to research presented Thursday at the American Orthopedic Society of Sports Medicine Annual Meeting. These root tears can loosen up the meniscus, which may lead to cartilage damage. "Our study found a significant improvement in all clinical outcome scores in the surgery group at two-year follow-up," said Jason L. Dragoo, a researcher at Stanford Medicine and study author, in a news release. The study included 48 people ages 50 and older who tore their meniscal root...
Subclinical heart disease may cause more falls in older people

Subclinical heart disease may cause more falls in older people

Health
July 10 (UPI) -- Heart damage in older adults may be leading to more falls, new research shows. Adults around age 75 with subclinical myocardial damage and cardiac wall strain are at a higher risk of falling than those without those conditions, according to a study published Wednesday in the Journal of the American Geriatrics Society. These findings suggest increasing heart health could prevent their falls from occurring within the older population. "Given that falls can often be fatal for older adults, greater knowledge of the factors that contribute to falls represents a significant public health priority," Stephen Juraschek, a primary care physician at Beth Israel Deaconess Medical Center and study lead author, said in a news release. "For the first time, our study shows that subclini...
Leg fat ‘better than belly fat’ for older women

Leg fat ‘better than belly fat’ for older women

Health
Carrying more fat on legs compared with the stomach protects postmenopausal women from heart disease, a study says.Women of a healthy weight with the highest risk of stroke or heart disease had the most belly fat and the least hip and thigh fat, the European Heart Journal research found. The scientists said "apple-shaped" women should try to lose belly fat and become more "pear-shaped".More research is needed to find out why the link exists, a heart charity said.What did the researchers do?The research followed 2,600 women who were a healthy weight - with a body mass index (BMI) of between 18 and 25 - over 18 years.They were all taking part in a major US study, the Women's Health Initiative, which began in the mid-1990s, and had regular scans to check fat...
