Defenses Down: COVID Antibodies in Nose Decline First

Defenses Down: COVID Antibodies in Nose Decline FirstWEDNESDAY, Dec. 21, 2022 (HealthDay News) -- Researchers think they’ve figured out why people can become reinfected with COVID-19, despite immunity gained from either vaccination or a previous infection.It turns out that antibodies produced in the nose — the first line of defense against respiratory viruses like COVID — decline faster than antibodies found in the bloodstream, British scientists say.Nasal antibodies tend to drop nine months after COVID-19 infection, while antibodies in the blood last at least a year, according to findings published online Dec. 19 in the journal eBioMedicine.The study also found that vaccination is very effective in creating and boosting blood-borne antibodies that protect against severe disease, but had very little effect on nasal...

Winter & Kid`s Asthma: High Time for Flare-UpsWEDNESDAY, Dec. 21, 2022 (HealthDay News) – Cold, dry winter air and a trio of spreading viruses could cause children's asthma to flare up this winter season.But experts at one children's hospital offer some tips to help parents keep their kids' worrisome respiratory symptoms in check. While asthma is a lung condition that can make it harder to breathe, some things can make symptoms worse, such as illness, cold air and smoke, according to Children's Minnesota in St. Paul and Minneapolis.To avoid cold-weather flare-ups, make sure your child has the right clothing to wear outside, including a scarf or neck warmer they can wear over their mouth and nose. This can help warm and humidify the air they breathe.Help prevent a case of influenza by washing hands frequently and making sure your...

Stranded Dolphins` Brains Show Alzheimer`s-Like ChangesWEDNESDAY, Dec. 21, 2022 (HealthDay News) -- Groups of whales, dolphins and porpoises are regularly stranded in shallow waters around the coasts of the United Kingdom.Researchers wanted to understand why, so they studied the brains of 22 toothed whales — or "odontocetes" — that were stranded in Scottish coastal waters.The study included five species — Risso’s dolphins, long-finned pilot whales, white-beaked dolphins, harbor porpoises and bottlenose dolphins. The research showed that four of the stranded animals from different dolphin species had some brain changes associated with Alzheimer’s disease in humans.“These are significant findings that show, for the first time, that the brain pathology in stranded odontocetes is similar to the brains of humans affected by...

People Are Still Evolving, Creating New Genes

People Are Still Evolving, Creating New GenesWEDNESDAY, Dec. 21, 2022 (HealthDay News) -- Humans have continued to evolve after splitting from chimpanzee ancestors nearly 7 million years ago, according to a new study that found 155 new genes unique to humans that suddenly arose from tiny sections of DNA.Some of the new genes date back to the ancient origin of mammals, according to the researchers. They suspect a few of these “microgenes” have links to human-specific diseases.“This project started back in 2017 because I was interested in novel gene evolution and figuring out how these genes originate,” said study author Nikolaos Vakirlis, a scientist at the Biomedical Sciences Research Center Alexander Fleming in Vari, Greece. “It was put on ice for a few years, until another study got published that had some very...

Stroke Can Leave Folks Thinking One Hand Is Bigger Than the Other

Stroke Can Leave Folks Thinking One Hand Is Bigger Than the OtherTUESDAY, Dec. 20, 2022 (HealthDay News) -- Imagine living day-to-day with one hand that feels like it's a baseball mitt, or another that feels like a small clutching claw.That’s the experience of many stroke survivors who suffer from chronic pain, according to a new study in the journal Brain Sciences.Stroke survivors living with chronic pain are almost three times as likely as pain-free survivors to experience altered body perception, researchers found.Specifically, their pain-afflicted brain tricks them into believing that a stroke-affected hand is either bigger or smaller than it actually is, results showed."These remarkable findings show us that we are perhaps more complex creatures than we previously thought," study co-author Lorimer Moseley, an international pain expert with...

Adult Children Far More Likely to Be Estranged From Dad Than Mom

Adult Children Far More Likely to Be Estranged From Dad Than MomTUESDAY, Dec. 20, 2022 (HealthDay News) -- Many young U.S. adults are estranged from their parents, at least temporarily -- with the father/child bond being especially fragile.Those are among the findings of a new national study that tracked thousands of parent-child relationships from the 1990s to recent years.Researchers found that one-quarter of young adults were estranged from their fathers at some point -- four times the number who reported broken ties with their mother.Often, those relationships got back on track to some degree, but reconciliation was less likely with fathers: Of adults who were estranged from their mother at some point, 81% got back in contact; that compared with 69% of people who were estranged from their father.One of the messages from the findings is that...

Pandemic Brought Surge in Teen Drug Overdose Deaths

Pandemic Brought Surge in Teen Drug Overdose DeathsTUESDAY, Dec. 20, 2022 (HealthDay News) -- Deaths of teens from drug overdoses soared starting in late 2019, and though they appear to be on the decline, they remain much higher than in 2019, U.S. health officials report.Most of these deaths are due to illegally made fentanyl mixed with other drugs, said study author Lauren Tanz, an epidemiologist at the U.S. Centers for Disease Control and Prevention."Adolescent overdose deaths increased substantially between 2019 and 2021; however, these deaths are preventable, and overdoses do not have to end in death," Tanz said. "We all play a role as parents, family members, friends and communities to prevent overdoses and save lives."Using data from the CDC’s State Unintentional Drug Overdose Reporting System, the researchers found that...

AHA News: Heart Transplant Recipient Honors Her Donor `By Living the Best Possible Life I Can`TUESDAY, Dec. 20, 2022 (American Heart Association News) -- Even now, years later, Linda Jara's voice resonates with notes that can only be fully appreciated by certain people – people like her who carry someone else's heart.Her tone is filled with gratitude. Awe. Contemplation. Thoughtfulness. Sorrow. Exuberance. The overwhelming feeling that someone else – a total stranger – made the ultimate sacrifice of allowing their own heart to beat in someone else's chest."It's an emotional process to wrap your head around the idea of losing your heart, all the things associated with the heart," said Jara, who lives in Philadelphia. "But it's more of what's in our brain. I'm still going to love the same people; it was just the idea of losing the organ that represents all the love I've had...
