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...

HPV: What It Is, Symptoms in Men vs. Women & TreatmentTUESDAY, May 30, 2023 (HealthDay News) -- Talking about sexually transmitted infections (STIs) can be uncomfortable. But whether you’re talking to your partner, child or doctor, these are important conversations to have.The U.S. Centers for Disease Control and Prevention estimates 20% of Americans had an STI in 2018. There are still more undetected, unreported and untreated STIs that can result in “serious health consequences.”Human papillomavirus (HPV) is the most common STI in the United States, so it’s important to know the facts.What is HPV?The CDC reports there were 43 million HPV infections in the United States in 2018. It’s a virus, and Mayo Clinic says it’s so widespread that an estimated 85% of all people will become infected with HPV in their lifetime.Dr. Nipunie...

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...

Compounds in Chocolate, Berries Might Help Boost Memory As You Age

Compounds in Chocolate, Berries Might Help Boost Memory As You AgeTUESDAY, May 30, 2023 (HealthDay News) -- You'll likely lose some of your memory and thinking abilities as you age, but nutrients called flavanols might help thwart that decline, a new study suggests.Not getting enough flavanols -- natural compounds found in fruits, vegetables and even chocolate -- could be driving that age-related memory loss, researchers say.This research is the pinnacle of 15 years of work showing that flavanols seem to benefit the dentate gyrus, an area within the brain’s hippocampus that is critical to memory.“This is the first time we can conclude that flavanols are acting as a nutrient for the aging brain,” said Dr. Scott Small, a professor of neurology and director of the Alzheimer’s Disease Research Center at Columbia University College of Physicians...

Could 'Brain Zap' Procedure Make Older Folks Smarter? Data Suggest It Might

Could `Brain Zap` Procedure Make Older Folks Smarter? Data Suggest It MightTUESDAY, May 30, 2023 (HealthDay News) -- For people who've lost some mental sharpness, to either aging or disease, a technique that gently "zaps" the brain circuitry is showing early promise.That's according to a new analysis of more than 100 studies assessing the technique, called transcranial alternating current stimulation, or tACS. It involves using electrodes on the scalp to send weak electrical pulses to specific brain areas.The premise behind tACS is based on the fact that brain activity naturally occurs in rhythmic patterns, or oscillations. Specific brain oscillations have been tied to various brain functions and states, with abnormal rhythms linked to a range of symptoms, including problems with memory and thinking.The electrical pulses from the tACS device essentially...

ER-Based Pharmacies Could Improve Kids` Care, Pediatricians` Group SaysTUESDAY, May 30, 2023 (HealthDay News) -- When parents rush their kids to an emergency room in the dead of night for an asthma attack or high fever, they are often discharged with a prescription. The problem is, there may be nowhere to fill it promptly.Now, a new report from the American Academy of Pediatrics (AAP) is calling attention to the issue, and highlighting one potential solution: 24-hour ER pharmacies.Studies have found that when children are prescribed medication in the emergency department, one-third to one-half of families never pick up the prescription.There are likely various reasons for this, but research shows that trouble getting to a pharmacy is a big obstacle, said Dr. Gregory Conners, chair of the AAP's committee on pediatric emergency medicine.Emergency department...
