The Arch of the Human Foot Was Key to Upright Walking, Scientists Say

The Arch of the Human Foot Was Key to Upright Walking, Scientists SayWEDNESDAY, May 31, 2023 (HealthDay News) -- That happy, confident spring in your step is likely a benefit imparted by human evolution, a new study argues.Humans may have evolved a spring-like arch in our feet to help us better walk and run upright, researchers say in their study, published May 30 in the journal Frontiers in Bioengineering and Biotechnology. It’s long been assumed that the raised arch of the foot helps us walk by acting as a lever that propels the body forward, researchers said in background notes.But a global team of scientists have now found that the recoil of the flexible arch also repositions the ankle upright for more effective walking.This recoil provides more aid in running, which suggests that people evolved a flexible arch to help them run more efficiently,...

Viruses in the Gut Might Help People Live to Be 100WEDNESDAY, May 31, 2023 (HealthDay News) -- A key to living to 100 may be the viruses living in a centenarian’s guts.“This snapshot of how the virome interacts with gut microbiomes could tell us about how microbial and viral ecology evolves over the lifetime of a person,” said Ramnik Xavier, director of immunology and co-director of the infectious disease and microbiome program at the Broad Institute of MIT (Massachusetts Institute of Technology), in Cambridge, Mass. "This offers an important starting point for uncovering the mechanisms behind how the gut ecosystem maintains health," Xavier said in a news release from the journal Nature Microbiology.The virome is the collection of viruses in the gut, while the microbiome is the community of microorganisms.Studying almost 200...

Worried About Cataracts? Here`s What You Need to KnowWEDNESDAY, May 31, 2023 (HealthDay News) -- Cataracts are the leading cause of blindness around the world, but surgery can restore vision.“Unlike many of the other major eye diseases, such as glaucoma or diabetes-related eye disease, cataracts can be easily and painlessly treated by surgery to remove and replace the eye’s lens, restoring sight for most patients,” said Jeff Todd, president and CEO of the nonprofit organization Prevent Blindness. “We urge patients to work with their eye doctor to understand their diagnosis and the best available treatment options,” Todd said in a news release from the organization.Here what else you should know about the common condition:More than half of all Americans will have a cataract, a clouding of the eye’s lens that blocks or changes...

What Is Avascular Necrosis and How Does It Affect Bones?

What Is Avascular Necrosis and How Does It Affect Bones?WEDNESDAY, May 31, 2023 (HealthDay News) -- What happens when the blood supply to your bones is somehow damaged?The condition has a name, avascular necrosis, and it can trigger the death of bone cells. Other common names are osteonecrosis or bone infarction. Bone is alive and requires nourishment from the blood supply to stay healthy. If the blood supply is not restored to the bone, small cracks develop and the bone can fracture and collapse. Avascular necrosis commonly occurs in the hips, knees, shoulders, elbows and ankles.Causes and risk factorsAvascular necrosis is caused by injury to the small blood vessels around joints. These injuries can include trauma to the joint, such as a dislocation of the joint or fracture of the surrounding bone. Other causes of injury to the blood...

4,000-Year-Old DNA Identifies Britain`s Oldest Known Case of PlagueWEDNESDAY, May 31, 2023 (HealthDay News) -- Researchers have identified the oldest cases of plague in Britain to date, with DNA that is 4,000 years old. The team from the Francis Crick Institute in London has found three ancient British cases of Yersinia pestis -- the bacteria that causes the plague -- in skeleton samples of two children and one woman. Two of the cases were found in a mass burial site in Charterhouse Warren in Somerset. The third was discovered in a ring cairn monument in Levens in Cumbria after researchers took skeletal samples of teeth from 34 people at the two sites.The scientists drilled into the teeth and extracted dental pulp, which can trap DNA remnants of infectious diseases. They then analyzed DNA and found Yersinia pestis in the two children, who were ages...

AHA News: Higher Cardiovascular Risk Score Linked to Lower Cognitive Function

AHA News: Higher Cardiovascular Risk Score Linked to Lower Cognitive FunctionTUESDAY, May 30, 2023 (American Heart Association News) -- A risk calculator used to predict cardiovascular disease also may help predict a person's poor cognitive function, new research suggests.The study, published Tuesday in the Journal of the American Heart Association, found that the higher a person's 10-year cardiovascular risk score, the worse they scored on tests for cognitive function, adding to a large body of evidence suggesting that controlling heart-health risk factors may help protect brain health."We know that cardiovascular disease shares a lot of risk factors with cognitive decline or dementia," said study co-author Jingkai Wei, who holds a doctorate in epidemiology and is an assistant professor at the University of South Carolina's Arnold School of Public Health in...

More 'Height-Challenged' Men Are Getting Leg-Lengthening Surgeries

More `Height-Challenged` Men Are Getting Leg-Lengthening SurgeriesTUESDAY, May 30, 2023 (HealthDay News) -- Some short men really struggle with their lack of height, feeling that they are both literally and figuratively looked down upon by others.That’s why an increasing number of height-challenged men are turning to limb-lengthening surgery -- an expensive, potentially painful, months-long procedure that will add a few extra inches to their frame.Limb-lengthening procedures have been around for decades, and have been typically used to correct illnesses and birth defects that cause one leg to be shorter than the other, said Dr. David Frumberg, co-director of the Yale Limb Restoration and Lengthening Program.“You basically convince the body that there’s a hairline fracture, and you allow the body to set up a healing response,” Frumberg...
