For many people, reaching their mid-40s may bring unpleasant signs the body isn’t working as well as it once did. Previous research showed that resting energy use, or metabolic rate, didn’t change from ages 20 to 60. The changes in metabolism affect how the body reacts to alcohol or caffeine, although the health consequences aren’t yet clear. For example, the changes in alcohol metabolism might be because people are drinking more in their mid-40s, Snyder said. “But it will take time to sort out what individual changes mean and how we can tailor medications to those changes.

“Now, post-surgery and post recovery, I am able to see in dimmer lighting with my left eye,” Cook said. A treatment that used CRISPR was found to be safe and efficacious in improving vision among a small sample of patients with inherited blindness in the Phase 1/2 clinical trial that Cook participated in. Months following the treatment, Cook was sitting with friends on a balcony that had Christmas lights wrapped around the railing. Courtesy Olivia CookBefore the treatment, Cook said that she sometimes could conceal the vision challenges she has had.

The “X-Men: Apocalypse” star, 43, wrote in an Instagram post Wednesday that she was diagnosed with breast cancer last year and would not have discovered it if her physician, Dr. Thaïs Aliabadi, had not calculated her breast cancer risk score. A breast cancer risk assessment tool uses a statistical model to estimate a woman’s risk of developing breast cancer over the next five years as well as over her lifetime, or up to about age 90, according to the National Cancer Institute. Two models are commonly used as breast cancer risk assessment tools: the Gail Model and the Tyrer-Cuzick Risk Assessment Calculator. An online version of the breast cancer risk assessment tool, using the Gail Model, is available for anyone to take at bcrisktool.cancer.gov. In fact, some women who do not develop breast cancer have higher risk estimates than some women who do develop breast cancer,” according to the National Cancer Institute’s website.

☆ A single genetic tweak caused human ancestors to lose their tails 25 million years ago — but it came at a cost

A single genetic tweak that occurred among our ancestors 25 million years ago means humans today are unable to grow a tail, according to a new study. Scientists knew that a gene called TBXT was involved in the snipping of the tail. Asep Supriatna/Getty ImagesWandering DNA snipped off our tailsThe solution, they found, was in a type of "jumping gene" called an Alu element. Scientists found two Alu elements around a part of the TBXT gene, called Exon 6. Scientists tested their findings by inserting Alu sequences in mice.

☆ More people need transplants than there are organ donors. Pigs might offer a solution
▼ + stars: | 2024-01-30 | by ( Jen Christensen | ) edition.cnn.com time to read: +23 min

The need for more transplant organs is immense and growing. Researchers have transplanted genetically modified pig kidneys and hearts into people who were brain-dead to test whether they work in humans. Although Larry Faucette was too sick for a human heart transplant, University of Maryland doctors said he seemed physically strong enough for a genetically modified pig heart. It was more than a decade after the first heart transplant but long before such procedures became relatively routine. “We learned that the pig heart is an adequate substitute for a human heart.

☆ Near-death experiences tied to brain activity after death, study says

Many people see a bright light during their near-death experiences, experts say. “This latest report of persistent brain waves after cardiac arrest has been blown out of proportion by the media. “That is, those patients who had near-death experiences did not show the reported brain waves, and those who did show the reported brain waves did not report near-death experiences,” Greyson told CNN via email. Greyson, who was not involved in the new study, is the coeditor of “The Handbook of Near-Death Experiences: Thirty Years of Investigation.” He and cardiologist Dr. Pim van Lommel, a Dutch researcher and writer on near-death experiences, submitted comments to the journal to publish alongside the new study. It’s correct that the study was not able to match electrical activity with a near death experience in the same patient, Parnia said.

☆ Mitch McConnell May Be Experiencing Small Seizures, Doctors Suggest

A four-line letter, signed by the attending physician of Congress and released by Senator Mitch McConnell on Thursday, suggested that his recent spells of speechlessness were linked to “occasional lightheadedness” perhaps brought on by his recovery from a concussion last winter or “dehydration.”But seven neurologists, relying on what they described as unusually revealing video of Mr. McConnell freezing up in public twice recently, said in interviews Thursday and Friday that the episodes captured in real time likely pointed to more serious medical problems afflicting the longtime Republican leader. Some of the neurologists, while cautioning that they could not diagnose the minority leader from afar, said that the letter and other comments from Mr. McConnell’s office appeared to fall short of explaining why he abruptly stopped speaking during news conferences in late July and again on Wednesday. “If I gave that tape to a medical student and that was his explanation, I’d fail him,” said Dr. Orrin Devinsky, a professor of neurology at the NYU Grossman School of Medicine, referring to the account given by the attending physician of Congress on Thursday. “Medically, these episodes need to be taken seriously.”

☆ Scientists propose long Covid definition based on key symptoms in large study
▼ + stars: | 2023-05-25 | by ( Spencer Kimball | ) www.cnbc.com time to read: +4 min

South_agency | E+ | Getty ImagesScientists funded by the federal government have proposed a definition of long Covid based on symptoms identified in a large study published Thursday in the Journal of the American Medical Association. The scientists assigned points based on how much each symptom distinguished participants with long Covid from those who did not catch the virus. There are no tests that can diagnose long Covid based on markers in the blood. Scientists participating in RECOVER are trying to understand the underlying biology that causes long Covid, which could potentially lead to such tests in the future. Horwitz said the proposed definition could help create a rubric to diagnose patients with long Covid in a manner similar to Lupus.

☆ New study suggests Black women should be screened earlier for breast cancer
▼ + stars: | 2023-04-19 | by ( Jacqueline Howard | ) edition.cnn.com time to read: +12 min

CNN —A new study on breast cancer deaths raises questions around whether Black women should screen at earlier ages. Even though Black women have a 4% lower incidence rate of breast cancer than White women, they have a 40% higher breast cancer death rate. “When the breast cancer mortality rate for Black women in their 40s is 27 deaths per 100,000 person-years, this means 27 out of every 100,000 Black women aged 40-49 in the US die of breast cancer during one year of follow-up. They also wrote that health policy makers should pursue equity, not just equality, when it comes to breast cancer screening as a tool to help reduce breast cancer death rates. Having dense tissue in the breast can make it more difficult for radiologists to identify breast cancer on a mammogram, and women with dense breast tissue have a higher risk of breast cancer.

☆ Morning after pill brand speeds up retail access, doubles supply per pack

The brand is also introducing a new 2-count pack of its emergency contraception (which has a three-year expiration period). Julie rolled out a new two-count pack of its emergency contraception priced at $70. Cleland said a study done last year by the American Society for Emergency Contraception on access to emergency contraception in stores compared price at retail for branded and generic emergency contraception options. “Every time there is a new development on restrictions to reproduction health care, there’s a run on emergency contraceptive. Our retail partners confirmed this,” said Morrison, adding that news events continue to influence buying patterns for emergency contraceptive.

ADHD diagnoses and prescriptions have been increasing across all age groups since before the days of social media. The number of ADHD diagnoses in 2010 were almost five times what they were in 1999. And between 2007 and 2016, the number of diagnoses of ADHD in adults more than doubled. "I think we've definitely moved into an area of talking about mental health that's really positive. Watch the video above to learn more about the rise in ADHD in the United States and whether the health care system can handle the increase in demand.

☆ More than 100,000 Americans are waiting for an organ transplant
▼ + stars: | 2022-10-26 | by ( Charlotte Morabito | In Charlottemorabito | ) www.cnbc.com time to read: +3 min

There are more than 100,000 people in the United States waiting for an organ transplant, according to the United Network for Organ Sharing, known as UNOS. Only a little more than 50% of people waiting for an organ will receive one within five years, according to UNOS. The industry recognizes the importance of finding alternatives to using organs from deceased human donors to address the national shortage. "Even though we're all fascinated by transplant, the ultimate goal is to get rid of it," Caplan said. Watch the video above to learn more about how the organ transplant system works and what we can do to increase supply while also addressing the inequalities.

Other omicron subvariants that have piqued the interest — and concerns — of scientists read like a viral alphabet soup: BQ.1, BQ.1.1, BF.7. Ever since the omicron variant emerged, it's been omicron all the way down, with omicron subvariants splitting off into their own subvariants. Barouch's study was small, including just 35 people who'd had either the Covid vaccine or an omicron infection. Most, regardless of prior infection, had at least three doses of Covid vaccine. The World Health Organization is tracking more than 300 omicron subvariants worldwide, Maria Van Kerkhove, head of the WHO’s emerging diseases and zoonosis unit, said during a media briefing Wednesday.

Scientists may have found a culprit for what can trigger Crohn’s disease. Cadwell and his colleagues discovered the norovirus connection to Crohn’s fortuitously when they were studying mice that had been engineered to develop the intestinal disease. Many of the mice had gotten norovirus and “the mice developed intestinal abnormalities only in the presence of a viral infection,” Cadwell explained. On a hunch, the researchers treated the mice that had developed the rodent version of Crohn’s with the human version of the API5 protein. Crohn's treatments can worsen infectionsThat would be welcome news to Heather Schlueter, who learned three years ago that her excruciating abdominal pain was due to Crohn’s disease.
