 — 

Here’s a look at information and statistics concerning vaccines in the United States. For vaccines related to coronavirus, see Coronavirus Outbreak Timeline Fast Facts.

The Centers for Disease Control and Prevention (CDC) provides vaccine recommendations by age, as well as by disease.

For more than 100 years, there has been public discord regarding vaccines based on issues like individual rights, religious freedoms, distrust of government and the effects that vaccines may have on the health of children.

Exemptions to vaccines fall into three general categories: medical, religious and philosophical.

As of May 25, 2022, 44 states and the District of Columbia have enacted legislation allowing religious exemptions from vaccines, and 15 states allow philosophical (non-spiritual) exemptions.

1796 – Edward Jenner develops the smallpox vaccine, the world’s first successful vaccine.

1855 – Massachusetts mandates that school children are to be vaccinated (only the smallpox vaccine is available at the time).

February 20, 1905 – In Jacobson v. Massachusetts, the US Supreme Court upholds the State’s right to compel immunizing against smallpox.

November 13, 1922 – The US Supreme Court denies any constitutional violation in Zucht v. King in which Rosalyn Zucht believes that requiring vaccines violates her right to liberty without due process. The High Court opines that city ordinances that require vaccinations for children to attend school are a “discretion required for the protection of the public health.”

1952 – Dr. Jonas Salk and his team develop a vaccine for polio. A nationwide trial leads to the vaccine being declared in 1955 to be safe and effective.

1963 – The first measles vaccine is released. In 2000, the CDC declares the US has achieved measles elimination, defined as “the absence of continuous disease transmission for 12 months or more in a specific geographic area.” While the US has maintained measles elimination since, there are occasional outbreaks.

1986 – Congress passes the National Childhood Vaccine Injury Act. This coordinates vaccine activities across several government agencies to monitor vaccine safety, requires vaccine information statements are provided to those receiving vaccines, and creates the National Vaccine Injury Compensation Program to compensate those injured by vaccines on a “no fault” basis.

March 19, 1992 – Rolling Stone publishes an article by Tom Curtis, “The Origin of AIDS,” which presents a theory that ties HIV/AIDS to polio vaccines. Curtis writes that in the late 1950s, during a vaccination campaign in Africa, at least 325,000 people were immunized with a contaminated polio vaccine. The article alleges that the vaccine may have been contaminated with a monkey virus and is the cause of the human immunodeficiency virus, later known as HIV/AIDS.

August 10, 1993 – Congress passes the Omnibus Budget Reconciliation Act which creates the Vaccines for Children Program, providing qualified children free vaccines.

December 9, 1993 – Rolling Stone publishes an update to the Curtis article, clarifying that his theory was not fact, and Rolling Stone did not mean to suggest there was any scientific proof to support it, and the magazine regrets any damage caused by the article.

1998 – British researcher Andrew Wakefield and 12 other authors publish a paper stating they had evidence that linked the vaccination for Measles, Mumps and Rubella (MMR) to autism. They claim they discovered the measles virus in the digestive systems of autistic children who were given the measles, mumps and rubella (MMR) vaccine. The publication leads to a widespread increase in the number of parents choosing not to vaccinate their children for fear of its link to autism.

2004 – Co-authors of the Wakefield study begin removing their names from the article when they discover Wakefield had been paid by lawyers representing parents who planned to sue vaccine manufacturers.

May 14, 2004 – The Institute of Medicine releases a report “rejecting a causal relationship between the MMR vaccine and autism.”

February 2010 – The Lancet, the British medical journal that published Wakefield’s study, officially retracts the article. Britain also revokes Wakefield’s medical license.

2011 – Investigative reporter Brian Deer writes a series of articles in the BMJ exposing Wakefield’s fraud. The articles state that he used distorted data and falsified medical histories of children that may have led to an unfounded relationship between vaccines and the development of autism.

2011 – The US Public Health Service finds that 63% of parents who refuse and delay vaccines do so for fear their children could have serious side effects.

June 17, 2014 – After analyzing 10 studies, all of which looked at whether there was a link between vaccines and autism and involved a total of over one million children, the University of Sydney publishes a report saying there is no correlation between vaccinations and the development of autism.

February 2015 – Advocacy group Autism Speaks releases a statement, “Over the last two decades, extensive research has asked whether there is any link between childhood vaccinations and autism. The results of this research are clear: Vaccines do not cause autism. We urge that all children be fully vaccinated.

August 23, 2018 – A study published in the American Journal of Public Health finds that Twitter accounts run by automated bots and Russian trolls masqueraded as legitimate users engaging in online vaccine debates. The bots and trolls posted a variety of anti-, pro- and neutral tweets and directly confronted vaccine skeptics, which “legitimize” the vaccine debate, according to the researchers.

October 11, 2018 – Two reports published by the CDC find that vaccine exemption rates and the percentage of unvaccinated children are on the rise.

January 2019 – The World Health Organization names vaccine hesitancy as one of 10 threats to global health in 2019.

September 4, 2019 – Facebook announces that educational pop-up windows will appear on the social media platforms when a user searches for vaccine-related content, visits vaccine-related Facebook groups and pages, or taps a vaccine-related hashtag on Instagram

December 19, 2019 – The US Food and Drug administration announces the approval of a vaccine for the prevention of the Ebola virus for the first time in the United States. The vaccine, Ervebo, was developed by Merck and protects against Ebola virus disease caused by Zaire ebolavirus in people 18 and older.

December 27, 2019 – A study published in the medical journal JAMA Network Open finds that a single dose of the human papillomavirus (HPV) vaccine may be just as effective as two or three doses at preventing cancer-causing HPV infection.

February 3, 2020 – The National Institute of Allergy and Infectious Diseases (NIAID) announces that a clinical trial for an HIV vaccine has been discontinued since the vaccine was not found to prevent infections of human immunodeficiency virus, the virus that causes AIDS.

May 3, 2023 – The US FDA approves, Arexvy, the first vaccine to protect against respiratory syncytial virus or RSV. It is a single shot for adults 60 or older.

Sleep apnea raises risk of long Covid by up to 75% for some, study says | CNN



CNN
 — 

Adults who have obstructive sleep apnea have up to an 75% increased risk, on average, of developing long Covid after a SARS-CoV-2 infection compared with people without sleep apnea, a new study found.

Women with obstructive sleep apnea had up to an 89% increased risk, while men had a 59% higher risk, according to the analysis of electronic health data on nearly 1.8 million people.

Obstructive sleep apnea is a potentially dangerous disorder in which breathing stops for about 10 seconds multiple times during the night due to a blockage of the airways by heavy or relaxed soft tissues in the mouth and throat.

A second analysis of medical records of a smaller group of 330,000 adults found the risk to be only 12%, according to the study, which is part of RECOVER, or Researching Covid to Enhance Recovery. RECOVER is a National Institutes of Health initiative dedicated to understanding why some people develop long Covid and how best to detect, treat, and prevent the condition.

Why the huge difference in numbers? People in the larger study had additional health concerns, or comorbidities, such as obesity, diabetes, high blood pressure and heart disease, said senior study author Lorna Thorpe, co-lead of the RECOVER Clinical Science Core at NYU Langone Health.

“The range of 12% to 75% is likely due to a combination of different study populations and different levels of comorbidities, but also different definitions of long Covid,” she said. “We didn’t even have a diagnostic code for long Covid until October 2021.

“I believe the risk is likely to be in the middle, but we will need additional studies to tease that out,” added Thorpe, a professor and director of the division of epidemiology at NYU Grossman School of Medicine.

A third analysis of medical records of 102,000 children with sleep apnea found no correlation between sleep apnea and long Covid after the various confounding health conditions were factored out, “which, of course, is great news,” Thorpe said.

“By using three very large networks of electronic health records, we were able to do this study three times, which is one of the strengths of the research,” she added. “This study is the first collaboration of this focus and scale to find that adults with sleep apnea are at greater risk for long Covid.”

This is an “important study” on long Covid, said Dr. Sairam Parthasarathy, a principal investigator of the University of Arizona Health Sciences RECOVER Adult Study and professor of medicine.

“Research needs to be done in a prospective study to verify this association, and if found to be true these findings have implications for treatment of long Covid,” said Parthasarathy, who was not involved in the study.

“It is important to note that some of the symptoms of long Covid such as fatigue may be related to obstructive sleep apnea, and that the treatment of obstructive sleep apnea may improve such long Covid-related symptoms,” he added.

The study, published Thursday in the journal Sleep, is one of a several studies released since Congress allocated $1.15 billion to NIH in January 2021, to study the long-term effects of Covid over a four-year period. To date, the agency says it has used about $811 million to fund research.

Researchers wanted to investigate the role of sleep apnea in long Covid due to the well-known association between the condition and poorer outcomes after a Covid infection.

“People with sleep apnea are at higher risk for a more severe case of Covid-19, admission to intensive care at the hospital and for mortality,” Thorpe said.

“Obstructive sleep apnea can result in increased inflammation, potentially disrupted sleep leading to an increased propensity to develop infections and reduced immunity,” said Dr. Bhanu Prakash Kolla, a sleep medicine specialist in the Center for Sleep Medicine at the Mayo Clinic in Rochester, Minnesota.

“This could potentially explain the pathway by which obstructive sleep apnea leads to an increased risk of having Covid and also … (long Covid),” said Kolla, who was not involved in the study.

Sleep apnea is an underdiagnosed condition regardless of gender, said the University of Arizona’s Parthasarathy.

“It is conservatively estimated that 80% of patients with obstructive sleep apnea (OSA) are not diagnosed,” he said. In addition, “an assumption with these analyses is that patients with OSA are likely to be treated. However, nearly half of them are not using the treatment.”

Why would women have up to an 89% higher risk compared with 59% in men? The study did not address that issue.

However, “one can postulate this difference may be based on what we know about sex differences in sleep and immune responses,” said Dr. Phyllis Zee, director of the Center for Circadian and Sleep Medicine at Northwestern University Feinberg School of Medicine in Chicago.

Zee, who was not involved with the new research, coauthored one of the first published studies on the link between sleep apnea and serious Covid infection.

“Women typically have stronger immune responses to viral infections, and thus also vulnerability for post-infection inflammation,” Zee said. “Women in general have more insomnia and with long Covid tend to present with fatigue and insomnia symptoms, which are also common symptoms of long Covid.”

Another reason could be that sleep apnea has historically been considered a male disease, Thorpe said, which could mean that by the time a woman is diagnosed her apnea is more advanced.

“It could be that the women who are documented in electronic health records have more severe sleep apnea because physicians more often look for sleep apnea among men,” she said.

As scientists continue to learn more about long Covid, further information will become available, Thorpe said. In the meantime, people who have sleep apnea — or who snore, snort and stop breathing at night, which are all signs of the condition — should be exceedingly careful when they contact Covid.

“People with sleep apnea who get infected with Covid should seek early treatment and consider getting Paxlovid, the oral medication prescribed to reduce risk of severe outcomes,” Thorpe said. “They should also keep up with their vaccinations to lower the risk of infection in the first place.”

What happens if you wake up before your alarm? Tips from sleep experts | CNN

Sign up for CNN’s Sleep, But Better newsletter series. Our seven-part guide has helpful hints to achieve better sleep.



CNN
 — 

Many people dread the blaring sound of an alarm clock, signaling the start of a busy workday. Others wish they weren’t already awake and that the sound had actually woken them up.

Waking up many minutes or even hours before the alarm is not a new phenomenon, sleep experts tell CNN, but it can cause people discomfort.

More than a third of Americans get fewer hours of sleep a night than the minimum recommendation of seven hours, according to the US Centers for Disease Control and Prevention. According to the National Institutes of Health, studies across the globe show anywhere from 10% to 30% of the population struggles with insomnia, defined as the consistent difficulty falling asleep and the inability to return to sleep after going to bed.

Those experiencing insomnia can have a combination of “nocturnal awakenings” and what’s categorized as “early morning awakenings,” according to a 2009 study from the Stanford Sleep Epidemiology Research Center and other universities. The study finds that some people may experience early awakenings without other insomnia symptoms such as “difficulty initiating sleep,” “nocturnal awakenings” and “non-restorative sleep,” meaning sleep that isn’t substantial even with the recommended hours.

While insomnia treatments include cognitive behavioral therapy and medication, other daily tips can have an impact on early morning awakenings. An acute sleep disorder could be at play for someone not experiencing chronic insomnia but waking up early.

The constant waking up before that daily sound is coupled with an immense frustration about not falling back asleep. The stress can feel isolating and all-consuming, taking more precedence than the initial sleep problem.

“You start ruminating about it, and then you start doing things that make insomnia worse,” said Dr. Rajkumar Dasgupta, associate professor of clinical medicine at the University of Southern California Keck School of Medicine in Los Angeles.

“Don’t start telling yourself … ‘I’m going to make myself stay in bed until I fall asleep,’ ” he said.

So, what can you do about it?

If you wake up suddenly — in what feels like the early morning hours — resist checking the clock. Finding out it’s 3 a.m. when you set the alarm for 7 a.m. can cause increased worry about the hours of sleep you hoped to attain.

“The anxiety and the frustration build,” said sleep specialist Wendy Troxel, a senior behavioral scientist at Rand Corp. “Clock watching becomes habitual, and that habitual response of frustration and anxiety also causes a stress response in the body.”

When anxiety and worry take precedence, cortisol levels increase, and the body becomes alert. This process is counterproductive for maintaining drowsiness, as the brain becomes hyper-engaged.

“You look at the clock. It’s 3 o’clock in the morning like clockwork, and immediately might grit your teeth. You think of all the demands … how awful it is going to be when you’re sleep-deprived,” Troxel said. “All of this mental processing and agitation is antithetical to the sleep state. It’s making you more alert and aroused … versus sending the signal to the brain that it’s OK to drift.”

If your alarm is on the phone, checking the clock can pose an even more significant trigger. Consider getting an alarm that isn’t attached to your phone.

“Our phone is our strongest signal to our waking lives,” Troxel said. “You’re getting the light exposure from your phone, which can directly stimulate your circadian signal for alertness. The content of what we are consuming on our phones can be very activating, whether it’s scrolling through social media or reading the news. These can all stimulate emotional states that are more activating rather than relaxing.”

Paradoxically, experts say to get out of bed. Yes, even at 3 a.m.

“Abandon the idea of getting back to sleep,” Troxel said. “When you do that, when you let the pressure go that sleep isn’t so effortful, sleep is more likely to come back.”

In a stimulus control technique, you can distract your brain with a mundane task to help bring back drowsiness faster than staying frustrated in bed.

Mentally assigning the bed with sleeping helps people associate positive sleep thoughts with their space. Leaving the room when agitation sets in can separate the frustration from the bed.

Anything from reading a book to knitting or listening to soft music (but not using a phone) can positively distract the brain. Once drowsiness sets in again, head back to bed.

Dasgupta recommends keeping track not only of when you went to bed and woke up on a given night, but also the calming techniques, environmental factors — and even nutrition and exercise routines that seemed to help you sleep that day.

“Perfect sleep is like having a puzzle, and you need all the right pieces,” Dasgupta said. “People who have insomnia, they’re missing one of those sleep hygiene pieces. When you make your recommendation, like a muscle relaxation, maybe that’s not the thing that they were missing. Maybe sound wasn’t the key part. Maybe you need more of that weighted blanket.”

It also depends on our given circadian rhythm, or the 24-hour solar cycle the body runs on that alerts us when sleepiness sets at night. If any environmental factors change — such as travel, work schedule or lighting — the body’s circadian rhythm may be thrown off, signaling an uncomfortable early wake-up before the alarm, Dasgupta said. In this case, changing the lighting in a given room or getting alternative lighting could help.

Progressive muscle relaxation may work — start at the toes, clench the given muscles for three seconds and release. Breathe through this process. The 4-7-8 breathing exercise coupled with muscle relaxation can be successful, Dasgupta said. Breathe in for 4 seconds, hold it for 7 seconds and breathe out for 8 seconds.

Others may find that yoga, meditation or reading can help when they wake up before their alarm. The same techniques don’t work for everyone, but practicing various strategies that may affect sleep is critical, ultimately building a well-followed routine.

If the problem continues beyond three times a week for three months, experts recommend talking to a sleep specialist. It may require more than a simple habit change.

Understanding how mosquitoes smell humans could save thousands of human lives | CNN



CNN
 — 

Of the more than 3,000 species of mosquitoes in the world, just a small number have evolved to specialize in sucking human blood.

How human-biting mosquitoes track us down so effectively isn’t currently known, but it matters, since they don’t just make us itch. They also carry dangerous diseases such as Zika, dengue, West Nile virus and malaria that can be deadly.

In fact, stopping these pesky insects in their tracks could save up to half a million lives lost to those diseases each year.

“In each of those cases where a mosquito has evolved to bite humans — which has only happened two or three times — they become nasty disease vectors,” said Carolyn “Lindy” McBride, an assistant professor of ecology and evolutionary biology at the Princeton Neuroscience Institute in New Jersey.

That’s why she wants to understand how they find and target humans.

“Mosquitoes mostly choose what to bite based on odor,” said McBride, whose lab focuses on the Aedes aegypti mosquito species that evolved to bite humans specifically.

Only female mosquitoes suck blood since they need it to produce their eggs. Knowing how a potentially disease-carrying female mosquito sniffs out a person, while ignoring other warm-blooded animals, is a key query.

Once that’s better known, much more effective repellents — or bait to lure mosquitoes away from humans — could be made, saving lives, said Christopher Potter, associate professor of neuroscience at Johns Hopkins University’s Center for Sensory Biology.

If scientists can control their sense of smell, “we can really control what these mosquitoes are doing,” said Potter, who studies another human-specific mosquito, Anopheles, which carries malaria.

It’s not an easy question to answer, since any animal smell is made up of hundreds of chemical compounds mixed together in specific ratios.

“The actual chemicals that are found in human odor are basically the same as the chemicals found in animal odor — it’s the ratios and the relative abundance of those compounds in human mixtures that’s unique,” said McBride, whose research focuses on those issues.

Each time a hungry female mosquito flies by, it’s doing complex chemical math in its tiny brain, figuring out what’s a human, what’s dog and what’s a flower.

“To investigate, we decided to record neural activity in the brain of females while exposing them to natural human and animal odor extracts,” wrote Zhilei Zhao, a graduate student in McBride’s lab, in a Twitter thread describing the lab’s work. It took four years to develop “the necessary genetic reagents, odor delivery systems, and analytical approaches,” Zhao wrote.

(From left) Noah Rose, a postdoctoral researcher at Princeton, and Gilbert Bianquinche survey a tree hole near Kedougou, Senegal, for Aedes aegypti larvae. More than half of the world's population lives in areas where Aedes aegypti mosquitoes are present.

McBride’s lab team created a library of the chemical composition of animal odors. “That data set doesn’t really exist — so we decided to go out and collect it ourselves,” said Jessica Zung, a graduate student in McBride’s lab.

Zung has collected scent samples from about 40 different animals so far, including guinea pigs, rats, quail and more.

Comparing some of those to the 16 human samples, something jumped out. Decanal, a simple, common compound, is particularly abundant in human skin, Zung said.

Ubiquitous in the natural world, in humans, decanal comes from another, more complex compound. Zung dug into the archives to find research from the 1970s (much of it originally done to find an acne cure) that detailed how when one component of our skin’s natural oils, sapienic acid, breaks down, decanal is left over. This acid (as indicated by its name) is only found in human beings. It’s what likely leads to the high levels of decanal that help the mosquitoes smell their way to us, but more studies need to be done.

Understanding what the mosquitoes are sniffing out is only part of the story; knowing how they do it is also important. To see exactly how mosquitoes use this sense, scientists bred genetically modified Aedes aegypti mosquitoes “so that we could cut open their little tiny heads and put them under a fancy microscope and actually watch neurons firing when they’re exposed to human and animal odors,” McBride said.

The research team already knew that mosquitoes have about 60 different types of neurons that sense odors, so when they looked in the insects’ brains, they thought they might see a lot of activity. But it was surprisingly quiet, meaning that the signal was perhaps quite simple, down to just a couple types of neurons.

“One type of neuron responded really strongly to both humans and animals. Another type of neuron responded to both — but it responded much more strongly to humans than animals,” McBride said of that work. So it may be as simple as that mosquito’s brain comparing just two types of neurons.

This kind of research has only been possible since the technology to study mosquito brains in detail became available, which only happened recently. “It’s been traditionally very hard to study this at the level we’re doing it now,” Potter said.

Incredibly, mosquitoes that target humans have evolved to be able to do this in just the last 5,000 years, so it’s a “really amazing example of rapid evolution,” McBride said.

The Aedes aegypti, aka “yellow fever mosquito” also carries dengue, Zika and chikungunya. The critter originated in Africa and likely made its way to its current range in the southern United States and Central and South America on slave ships during the 1600s, according to McBride.

These diseases combined kill and sicken thousands of people a year, which is why mosquitoes have been called “the world’s deadliest animal” by the US Centers for Disease Control and Prevention. McBride and Potter both hope their work could be used by others working on repellents and attractants to prevent disease.

As far as insider knowledge on how to keep from being bitten in your own backyard, McBride said she uses a fan.

“Have it blow air over where you’re sitting outside or over the barbecue or under the table where they’re biting your feet.” It’s not that you’re blowing the scent around to knock the mosquitoes off track, she said.

It’s simply because these deadly creatures, McBride said, “are not great fliers.”

It’s a myth that women don’t want sex as they age, study finds | CNN



CNN
 — 

It’s a myth that women lose interest in sex as they enter midlife and beyond, according to research that followed more than 3,200 women for about 15 years.

“About a quarter of women rate sex as very important, regardless of their age,” said Dr. Holly Thomas, lead author of an abstract presented during the September 2020 virtual annual meeting of the North American Menopause Society.

“The study showed substantial numbers of women still highly value sex, even as they get older, and it’s not abnormal,” said Thomas, an assistant professor of medicine at the University of Pittsburgh.

“If women are able to speak up with their partner and make sure that they’re having sex that’s fulfilling and pleasurable to them, then they’re more likely to rate it as highly important as they get older,” she said.

“That’s actually quite refreshing, that there were a quarter of women for whom sex remains not just on the radar but highly important,” said Dr. Stephanie Faubion, medical director for the North American Menopause Society, who was not involved in the study.

“Studies like these provide valuable insights to health care providers who may otherwise dismiss a woman’s waning sexual desire as a natural part of aging.”

It’s true that past studies have found that women tend to lose interest in sex as they age. But women’s health practitioners say that attitude doesn’t jibe with the reality they see.

“Some of the prior studies had suggested that sex goes downhill and all women lose interest in sex as they get older,” Thomas said. “That really isn’t the type of story that I hear from all my patients.”

One issue, she said, is that past studies took a single snapshot of a woman’s desire at one point in her life and compared it with similar snapshots in later decades of life.

“That type of longitudinal study would just show averages over time,” Thomas said. “And if you look at things on average, it may look like everyone follows one path.”

The study presented in 2020 used a different type of analysis that allowed researchers to follow the trajectory of a woman’s desire over time, Thomas said then.

“We wanted to use this different type of technique to see if there really were these different patterns,” she said. “And when you look for these trajectories, you see there are significant groups of women who follow another path.”

The research, which analyzed data from a national multisite study called SWAN, or the Study of Women’s Health Across the Nation, found three distinct pathways in a woman’s feelings about the importance of sex.

About a fourth of the women (28%) followed traditional thinking on the subject: They valued sex less during midlife years.

However, another fourth of the women in the study said the exact opposite. Some 27% of them said sex remains highly important throughout their 40s, 50s and 60s — a surprising contradiction of the belief that all women lose interest in sex as they age.

“Sex is going to look different,” said Faubion, who is director of the Mayo Clinic’s Center for Women’s Health.

“It’s not going to look the same at 40 as it does at 20; it’s not going to look the same at 60 as it does at 40, and it’s not going to look the same at 80 as it did at 60,” she said. “There may be some modifications that we have to do, but people in general who are healthy and in good relationships remain sexual.”

Women in the study who highly valued sex shared the following characteristics: They were more highly educated, they were less depressed, and they had experienced better sexual satisfaction before entering midlife.

“Women who were having more satisfying sex when they were in their 40s were more likely to continue to highly value sex as they got older,” Thomas said.

There could also be socioeconomic factors at play, she added. For example, more highly educated women may have higher incomes and feel more stable in their lives with less stress.

“Therefore they have more headspace to make sex a priority because they’re not worrying about other things,” Thomas said.

The study found another factor important to both lower-interest and high-interest pathways — race and ethnicity.

African American women were more likely to say sex was important to them for the duration of midlife, while Chinese and Japanese women were more likely to rate sex as having low importance throughout their midlife years.

“I do want to emphasize that it’s much more likely to be due to sociocultural factors than any biological factor,” Thomas said. “Women from different cultural groups have different attitudes … different comfort levels about getting older … and whether it’s ‘normal’ for a woman to continue to value sex as she gets older.”

The majority of women (48%) fell into a third pathway: They valued a healthy sex life as they entered the menopausal years but gradually lost interest throughout their 50s or 60s.

There are a number of emotional, physical and psychological factors that might affect how a woman views sex, experts say. Most can be divided into four categories:

Medical conditions: As women enter perimenopause in their 40s and 50s, they begin to experience hormonal changes that can cause sex to become less satisfying or even painful.

The drop in estrogen causes the vulva and vaginal tissues to become thinner, drier and more easily broken, bruised or irritated. Arousal can become more difficult. Hot flashes and other signs of menopause can affect mood and sleep quality, leading to fatigue, anxiety, irritability, brain fog and depression.

Many medical conditions can arise or worsen during midlife that can also affect libido.

“Do they have medical conditions like hip arthritis that cause pain with sex? Or hand arthritis that can make it more difficult? Or things like diabetes where their sensation is not the same, or do they have heart disease?” Faubion asked.

“But there are modifications that we talk about all the time to help people remain sexual, even for quadriplegics,” she said. “There are ways to stay sexual despite disability.”

Mental and emotional considerations: The psychological component of sex can have a huge influence on a woman’s levels of sexual desire. A history of sexual or physical abuse, struggles with substance abuse and depression, anxiety and stress are major players in this category.

“I can’t tell you enough about the impact of anxiety and stress on sex,” Faubion said. “Think of that fight or flight mechanism — your adrenaline’s pumping so you’re back in caveman days and a lion is chasing you.

“Are you going to lie down on the grassy knoll and have sex when the lion is chasing you? The answer is no. And that’s how women with anxiety are all the time, so anxiety is a huge, huge factor for whether women will be sexual.”

While the study did not look specifically at anxiety, results showed women with more symptoms of depression were much less likely to rate sex as a priority in life. In addition to the emotional impact, a reduced libido is a side effect of many antidepressants prescribed to treat depression.

Partner component: Women in midlife can also face dramatic and disturbing changes in their romantic lives that can take a major toll on their interest in sex.

“Are they losing a romantic partner to divorce or to death? Is a romantic partner developing health issues that make sex more difficult or inconvenient? Are they getting busy in other aspects of their life — their career, caring for grandchildren or even grown children who are moving back in? That makes it hard to prioritize sex,” Thomas said.

Even if they have a partner, relationships may have had ups and downs that can affect how a woman feels about intimacy with a significant other.

“Do you like your partner?” Faubion asked. “Is your communication good? Even logistics can get in the way — are you in the same place at the same time?”

Social mores: Society also affects how a woman feels about sex. Religious, cultural and family values about the topic can play a large role in sexual ease and satisfaction.

“Then there’s what society teaches us about aging women,” Faubion said. “And so for some women being sexual is somehow bad. Women aren’t supposed to like sex.”

“I’ve seen plenty of women in my clinic in the 60-to-65 age group who never got any sex education, their partners never got any sex education, and they don’t really want to know about all that stuff.”

Of course, if a woman isn’t bothered by a lack of sex, then there’s no reason to see a doctor, Faubion and Thomas said. But they both said that past studies have shown that about 10% to 15% of women who do have a lower interest in sex are bothered by it and would like to seek a solution.

There are ways in which physicians can help, including medications and therapies, but first a woman must reach out and talk to her doctor.

“Prior research has shown that women often really do hesitate to reach out to their doctors, perhaps because they’re embarrassed or they see it as part of normal aging and and don’t think it’s worth bringing up,” Thomas said.

Faubion added, “Bottom line: Women should talk to their providers if they’re having concerns about their sexual health. It’s an important part of life, and there are solutions for women who are struggling with that.”

Conjoined Twins Fast Facts | CNN



CNN
 — 

Here’s a look at conjoined twins.

Conjoined twins are physically connected to one another at some point on their bodies.

Conjoined twins occur once every 200,000 live births, according to the University of Minnesota.

About 70% of conjoined twins are female.

Conjoined twins are identical – they are the same sex.

According to the Mayo Clinic, conjoined twins may be joined at any of these areas: chest, abdomen, spine, pelvis, trunk or head.

Scientists believe that conjoined twins develop from a single fertilized egg that fails to separate completely as it divides.

The term “Siamese twins” originated with Eng and Chang Bunker, a set of conjoined twins who were born in Siam (now Thailand) in 1811. They lived to age 63 and appeared in traveling exhibitions. Chang and Eng both married and fathered a total of 21 children between them.

In 1955, neurosurgeon Dr. Harold Voris of Mercy Hospital in Chicago performed the first successful procedure separating conjoined twins.

Opioid Crisis Fast Facts | CNN



CNN
 — 

Here’s a look at the opioid crisis.

Experts say the United States is in the throes of an opioid epidemic. An estimated 9.2 million Americans aged 12 and older misused opioids in 2021, including 8.7 million prescription pain reliever abusers and 1.1 million heroin users.

Opioids are drugs formulated to replicate the pain-reducing properties of opium. Prescription painkillers like morphine, oxycodone and hydrocodone are opioids. Illegal drugs like heroin and illicitly made fentanyl are also opioids. The word “opioid” is derived from the word “opium.”

Nearly 110,000 people died of drug overdoses in 2022, and more than two-thirds of those deaths involved a synthetic opioid.

Overdose deaths have been on the rise for years in the United States, but surged amid the Covid-19 pandemic: Annual deaths were nearly 50% higher in 2021 than in 2019, CDC data shows.

Prescription opioid volumes peaked in 2011, with the equivalent of 240 billion milligrams of morphine prescribed, according to the market research firm, IQVIA Institute for Human Data Science.

Alabama, Arkansas, Louisiana and Tennessee had the highest opioid dispensing rates in 2020.

Opioids such as morphine and codeine are naturally derived from opium poppy plants more commonly grown in Asia, Central America and South America. Heroin is an illegal drug synthesized from morphine.

Hydrocodone and oxycodone are semi-synthetic opioids, manufactured in labs with natural and synthetic ingredients.

Fentanyl is a fully synthetic opioid, originally developed as a powerful anesthetic for surgery. It is also administered to alleviate severe pain associated with terminal illnesses like cancer. The drug is up to 100 times more powerful than morphine. Just a small dose can be deadly. Illicitly produced fentanyl has been a driving factor in the number of overdose deaths in recent years.

Methadone is another fully synthetic opioid. It is commonly dispensed to recovering heroin addicts to relieve the symptoms of withdrawal.

Opioids bind to receptors in the brain and spinal cord, disrupting pain signals. They also activate the reward areas of the brain by releasing the hormone dopamine, creating a feeling of euphoria or a “high.”

Opioid use disorder is the clinical term for opioid addiction or abuse.

People who become dependent on opioids may experience withdrawal symptoms when they stop using the medication. Dependence is often coupled with tolerance, meaning that users need to take increasingly larger doses for the same effect.

A drug called naloxone, available as an injection or a nasal spray, is used as a treatment for overdoses. It blocks or reverses the effects of opioids and is often carried by first responders.

More data on overdose deaths

The 21st Century Cures Act, passed in 2016, allocated $1 billion over two years in opioid crisis grants to states, providing funding for expanded treatment and prevention programs. In April 2017, Health and Human Services Secretary Tom Price announced the distribution of the first round of $485 million in grants to all 50 states and US territories.

In August 2017, Attorney General Jeff Sessions announced the launch of an Opioid Fraud and Abuse Detection Unit within the Department of Justice. The unit’s mission is to prosecute individuals who commit opioid-related health care fraud. The DOJ is also appointing US attorneys who will specialize in opioid health care fraud cases as part of a three-year pilot program in 12 jurisdictions nationwide.

On October 24, 2018, President Donald Trump signed opioid legislation into law. The SUPPORT for Patients and Communities Act includes provisions aimed at promoting research to find new drugs for pain management that will not be addictive. It also expands access to treatment for substance use disorders for Medicaid patients.

State legislatures have also introduced measures to regulate pain clinics and limit the quantity of opioids that doctors can dispense.

1861-1865 – During the Civil War, medics use morphine as a battlefield anesthetic. Many soldiers become dependent on the drug.

1898 – Heroin is first produced commercially by the Bayer Company. At the time, heroin is believed to be less habit-forming than morphine, so it is dispensed to individuals who are addicted to morphine.

1914 – Congress passes the Harrison Narcotics Act, which requires that doctors write prescriptions for narcotic drugs like opioids and cocaine. Importers, manufacturers and distributors of narcotics must register with the Treasury Department and pay taxes on products

1924 – The Anti-Heroin Act bans the production and sale of heroin in the United States.

1970 – The Controlled Substances Act becomes law. It creates groupings (or schedules) of drugs based on the potential for abuse. Heroin is a Schedule I drug while morphine, fentanyl, oxycodone (Percocet) and methadone are Schedule II. Hydrocodone (Vicodin) is originally a Schedule III medication. It is later recategorized as a Schedule II drug.

January 10, 1980 – A letter titled “Addiction Rare in Patients Treated with Narcotics” is published in the New England Journal of Medicine. It looks at incidences of painkiller addiction in a very specific population of hospitalized patients who were closely monitored. It becomes widely cited as proof that narcotics are a safe treatment for chronic pain.

1995 – OxyContin, a long-acting version of oxycodone that slowly releases the drug over 12 hours, is introduced and aggressively marketed as a safer pain pill by manufacturer, Purdue Pharma.

May 10, 2007 – Purdue Pharma pleads guilty for misleadingly advertising OxyContin as safer and less addictive than other opioids. The company and three executives are charged with “misleading and defrauding physicians and consumers.” Purdue and the executives agree to pay $634.5 million in criminal and civil fines.

2010 – FDA approves an “abuse-deterrent” formulation of OxyContin, to help curb abuse. However, people still find ways to abuse it.

May 20, 2015 – The DEA announces that it has arrested 280 people, including 22 doctors and pharmacists, after a 15-month sting operation centered on health care providers who dispense large amounts of opioids. The sting, dubbed Operation Pilluted, is the largest prescription drug bust in the history of the DEA.

March 18, 2016 – The CDC publishes guidelines for prescribing opioids for patients with chronic pain. Recommendations include prescribing over-the-counter pain relievers like acetaminophen and ibuprofen in lieu of opioids. Doctors are encouraged to promote exercise and behavioral treatments to help patients cope with pain.

March 29, 2017 – Trump signs an executive order calling for the establishment of the President’s Commission on Combating Drug Addiction and the Opioid Crisis. New Jersey Governor Chris Christie is selected as the chairman of the group, with Trump’s son-in-law, Jared Kushner, as an adviser.

July 31, 2017 – After a delay, the White House panel examining the nation’s opioid epidemic releases its interim report, asking Trump to declare a national public health emergency to combat the ongoing crisis

September 22, 2017 – The pharmacy chain CVS announces that it will implement new restrictions on filling prescriptions for opioids, dispensing a limited seven-day supply to patients who are new to pain therapy.

November 1, 2017 – The opioid commission releases its final report. Its 56 recommendations include a proposal to establish nationwide drug courts that would place opioid addicts in treatment facilities rather than prison.

February 9, 2018 – A budget agreement signed by Trump authorizes $6 billion for opioid programs, with $3 billion allocated for 2018 and $3 billion allocated for 2019.

February 27, 2018 – Sessions announces a new opioid initiative: The Prescription Interdiction & Litigation (PIL) Task Force. The mission of the task force is to support local jurisdictions that have filed lawsuits against prescription drugmakers and distributors.

March 19, 2018 – The Trump administration outlines an initiative to stop opioid abuse. The three areas of concentration are law enforcement and interdiction; prevention and education via an ad campaign; and job-seeking assistance for individuals fighting addiction.

April 9, 2018 – The US surgeon general issues an advisory recommending that Americans carry the opioid overdose-reversing drug, naloxone. A surgeon general advisory is a rarely used tool to convey an urgent message. The last advisory issued by the surgeon general, more than a decade ago, focused on drinking during pregnancy.

May 1, 2018 – The Journal of the American Medical Association publishes a study that finds synthetic opioids like fentanyl caused about 46% of opioid deaths in 2016. That’s a three-fold increase compared with 2010, when synthetic opioids were involved in about 14% of opioid overdose deaths. It’s the first time that synthetic opioids surpassed prescription opioids and heroin as the primary cause of overdose fatalities.

May 30, 2018 – The journal Medical Care publishes a study that estimates the cost of medical care and substance abuse treatment for opioid addiction was $78.5 billion in 2013.

June 7, 2018 – The White House announces a new multimillion dollar public awareness advertising campaign to combat opioid addiction. The first four ads of the campaign are all based on true stories illustrating the extreme lengths young adults have gone to obtain the powerful drugs.

December 12, 2018 – According to the National Center for Health Statistics, fentanyl is now the most commonly used drug involved in drug overdoses. The rate of drug overdoses involving the synthetic opioid skyrocketed by about 113% each year from 2013 through 2016.

January 14, 2019 – The National Safety Council finds that, for the first time on record, the odds of dying from an opioid overdose in the United States are now greater than those of dying in a vehicle crash.

March 26, 2019 – Purdue Pharma agrees to pay a $270 million settlement to settle a historic lawsuit brought by the Oklahoma attorney general. The settlement will be used to fund addiction research and help cities and counties with the opioid crisis.

July 17, 2019 – The CDC releases preliminary data showing a 5.1% decline in drug overdoses during 2018. If the preliminary number is accurate, it would mark the first annual drop in overdose deaths in more than two decades.

August 26, 2019 – Oklahoma wins its case against Johnson & Johnson in the first major opioid lawsuit trial to be held in the United States. Cleveland County District Judge Thad Balkman orders Johnson & Johnson to pay $572 million for its role in the state’s opioid crisis. The penalty is later reduced to $465 million, due to a mathematical error made when calculating the judgment. In November 2021, the Oklahoma Supreme Court reverses the decision.

September 15, 2019 – Purdue files for bankruptcy as part of a $10 billion agreement to settle opioid lawsuits. According to a statement from the chair of Purdue’s board of directors, the money will be allocated to communities nationwide struggling to address the crisis.

September 30, 2019 – The FDA and DEA announce that they sent warnings to four online networks, operating a total of 10 websites, which the agencies said are illegally marketing unapproved and misbranded versions of opioid medicines, including tramadol.

February 25, 2020 – Mallinckrodt, a large opioid manufacturer, reaches a settlement agreement in principle worth $1.6 billion. Mallinckrodt says the proposed deal will resolve all opioid-related claims against the company and its subsidiaries if it moves forward. Plaintiffs would receive payments over an eight-year period to cover the costs of opioid-addition treatments and other needs.

October 21, 2020 – The Justice Department announces that Purdue Pharma, the maker of OxyContin, has agreed to plead guilty to three federal criminal charges for its role in creating the nation’s opioid crisis. They agree to pay more than $8 billion and close down the company. The money will go to opioid treatment and abatement programs. The Justice Department also reached a separate $225 million civil settlement with the former owners of Purdue Pharma, the Sackler family. In November 2020, Purdue Pharma board chairman Steve Miller formally pleads guilty on behalf of the company.

March 15, 2021 – According to court documents, Purdue files a restructuring plan to dissolve itself and establish a new company dedicated to programs designed to combat the opioid crisis. As part of the proposed plan, the Sackler family agrees to pay an additional $4.2 billion over the next nine years to resolve various civil claims.

September 1, 2021 – In federal bankruptcy court, Judge Robert Drain rules that Purdue Pharma will be dissolved. The settlement agreement resolves all civil litigation against the Sackler family members, Purdue Pharma and other related parties and entities, and awards them broad legal protection against future civil litigation. The Sacklers will relinquish control of family foundations with over $175 million in assets to the trustees of a National Opioid Abatement Trust. On December 16, 2021, a federal judge overturns the settlement.

February 25, 2022 – Johnson & Johnson and the three largest US drug distributors – McKesson Corp, Cardinal Health Inc and AmerisourceBergen Corp – finalize a $26 billion nationwide opioid settlement.

March 3, 2022 – The Sackler families reaches a settlement with a group of states the first week of March, according to court filings. The settlement, ordered through court-ordered mediation that began in January, requires the Sacklers to pay out as much as $6 billion to states, individual claimants and opioid crisis abatement, if approved by a federal bankruptcy court judge.

November 2, 2022 – CVS and Walgreens agree to pay a combined $10 billion, over 10 and 15 years, to settle lawsuits brought by states and local governments alleging the retailers mishandled prescriptions of opioid painkillers.

Concern grows around US health-care workforce shortage: ‘We don’t have enough doctors’ | CNN



CNN
 — 

There is mounting concern among some US lawmakers about the nation’s ongoing shortage of health-care workers, and the leaders of historically Black medical schools are calling for more funding to train a more diverse workforce.

As of Monday, in areas where a health workforce shortage has been identified, the United States needs more than 17,000 additional primary care practitioners, 12,000 dental health practitioners and 8,200 mental health practitioners, according to data from the Health Resources & Services Administration. Those numbers are based on data that HRSA receives from state offices and health departments.

“We have nowhere near the kind of workforce, health-care workforce, that we need,” Vermont Sen. Bernie Sanders told CNN on Friday. “We don’t have enough doctors. We don’t have enough nurses. We don’t have enough psychologists or counselors for addiction. We don’t have enough pharmacists.”

The heads of historically Black medical schools met with Sanders in a roundtable at the Morehouse School of Medicine in Atlanta on Friday to discuss the nation’s health-care workforce shortage.

The health-care workforce shortage is “more acute” in Black and brown communities; the Black community constitutes 13% of the US population, but only 5.7% of US physicians are Black, said Sanders, chairman of the Senate Committee on Health, Education, Labor, and Pensions.

“What we’re trying to do in this committee – in our Health, Education, Labor Committee – is grow the health-care workforce and put a special emphasis on the needs to grow more Black doctors, nurses, psychologists, et cetera,” Sanders said.

At Friday’s roundtable, the leaders of the Morehouse School of Medicine, Meharry Medical College, Howard University and Charles R. Drew University called for more resources and opportunities to be allocated to their institutions to help grow the nation’s incoming health-care workforce.

“Allocating resources and opportunities matter for us to increase capacity and scholarships and programming to help support these students as they matriculate through,” Dr. Valerie Montgomery Rice, president of the Morehouse School of Medicine, told CNN.

“But also, the other 150-plus medical schools, beyond our four historically Black medical schools, owe it to the country to increase the diversity of the students that they train,” Rice said, adding that having a health-care workforce that reflects the communities served helps reduce the health inequities seen in the United States.

Historically Black medical schools are “the backbone for training Black doctors in this country,” Dr. Hugh Mighty, senior vice president for health affairs at Howard University, said at Friday’s event. “As the problem of Black physician shortages rise, within the general context of the physician workforce shortage, many communities of need will continue to be underserved.”

A new study commissioned by the National Institute on Minority Health and Health Disparities estimates that the economic burden of health inequities in the United States has cost the nation billions of dollars. Such inequities are illustrated in how Black and brown communities tend to have higher rates of serious health outcomes such as maternal deaths, certain chronic diseases and infectious diseases.

The researchers, from Johns Hopkins University and other institutions, analyzed excess medical care expenditures, death records and other US data from 2016 through 2019. They took a close look at health inequities in the cost of medical care, differences in premature deaths and the amount of labor market productivity that has been lost due to health reasons.

The researchers found that, in 2018, the economic burden of health inequities for racial and ethnic minority communities in the United States was up to $451 billion, and the economic burden of health inequities for adults without a four-year college degree was up to $978 billion.

“These findings provide a clear and important message to health care leaders, public health officials, and state and federal policy makers – the economic magnitude of health inequities in the US is startlingly high,” Drs. Rishi Wadhera and Issa Dahabreh, both of Harvard University, wrote in an editorial that accompanied the new study in the journal JAMA.

The Covid-19 pandemic “pulled the curtain back” on health inequities, such as premature death and others, Rice said, and “we saw a disproportionate burden” on some communities.

“We saw a higher death rate in Black and brown communities because of access and fear and a whole bunch of other factors, including what we recognize as racism and unconscious bias,” Rice said.

“We needed more physicians, more health-care providers. So, we already know when we project out to 2050, we have a significant physician shortage based on the fact that we cannot educate and train enough health care professionals fast enough,” she said. “We can’t just rely on physicians. We have to rely on a team approach.”

She added that the nation’s shortage of health-care workers leaves the country ill-prepared to respond to future pandemics.

The United States is projected to face a shortage of up to 124,000 physicians by 2034 as the demand outpaces supply, according to the Association of American Medical Colleges.

The workforce shortage means “we’re really not prepared” for another pandemic, Sanders said.

“We don’t have the public health infrastructure that we need state by state. We surely don’t have the doctors and the nurses that we need,” Sanders said. “So what we are trying to do now is to bring forth legislation, which will create more doctors and more nurses, more dentists, because dental care is a major crisis in America.”

In March, Bill McBride, executive director of the National Governors Association, wrote a letter to Sanders and Louisiana Sen. Bill Cassidy detailing the “root causes” of the health-care workforce shortage and potential ways some states are hoping to tackle the crisis.

“Governors have taken innovative steps to address the healthcare workforce shortage facing their states and territories by boosting recruitment efforts, loosening licensing requirements, expanding training programs and raising providers’ pay,” McBride wrote.

“Shortages in healthcare workers is not a new challenge but has only worsened in the past three years due to the COVID-19 pandemic. Burnout and stress have only exacerbated this issue,” he wrote. “The retirement and aging of an entire generation is front and center of the healthcare workforce shortage, particularly impacting rural communities.”

Older dogs who sleep badly may have dementia, study says | CNN



CNN
 — 

In a veterinary lab in North Carolina, Woofus, a 15-year-old basset hound mix, is allowing researchers to attach an electroencephalogram, or EEG, electrodes to his head before padding off to a dark, cozy room for an afternoon nap.

During his snooze, the study team will analyze Woofus’ brain waves to judge the quality of his sleep. Woofus has canine cognitive dysfunction syndrome, or CCDS, the doggie disorder that’s similar to Alzheimer’s disease in people. The elderly dog’s owners say he is struggling to get enough rest at night.

“Just like humans with Alzheimer’s disease, dogs with CCDS experience sleep disruptions, such as insomnia and sleep fragmentation,” said veterinarian Dr. Natasha Olby, a professor of neurology, neurosurgery and gerontology at North Carolina State College of Veterinary Medicine in Raleigh.

Woofus isn’t the only sleep-deprived dog in this study. On other days in the clinic, Jake, a 13-year-old pointer, and Coco, a 12-year-old dachshund, among others, might be taking a siesta while researchers peer inside their brains.

“Owners of dogs with CCDS report their dogs suffer from difficulty sleeping at night, increased sleeping during the day or both, as well as pacing and vocalizations at night,” Olby said. “This can be very hard on the dog’s owners — not only are they worried for their pet, their sleep is also significantly disrupted.”

To find out whether sleep problems in dogs indicate early signs of dementia as they do in people, Olby and her team turned to a group of senior dogs enrolled in an ongoing study testing antiaging supplements. The dogs visit twice a year “and do all kinds of really fun cognitive testing,” she said. “They really enjoy it and like the handlers they work with.”

To be considered for the antiaging study, the dog must have lived more than 75% of the expected life span for their breed or mix of breeds. A dog also could not be crippled by arthritis or going blind, as the pet needed to be able to perform tasks designed to test their cognitive capabilities.

A dog might be asked, for example, to find a treat hidden under a cup or a snack inside a cylinder in which one end had been closed by a researcher. By repeating the tasks at the clinic every six months, any decline in the dog’s mental agility or performance can be tracked.

Woofus, 15-year-old basset hound mix, plays

For the new study measuring a dog’s brain waves during sleep, researchers used a form of electroencephalogram called polysomnography, used in sleep clinics to diagnose sleep problems in people.

“It’s the gold standard method to look at what the brain is doing during sleep,” Olby said, adding this is the first canine study to apply the same technology used on humans.

“We glue these electrodes on with a really great conductive glue that’s water soluble. Then we just wash it off afterwards,” she said. “We don’t use anywhere near as many electrodes as you see on people in a sleep lab, because dogs have far less cortex and surface area to cover.”

Already at ease with the staff, it wasn’t too difficult to train 28 senior dogs to wear electrodes and walk around with dangling wires without complaint, she said.

Jake, a 13-year-old pointer, was one of 28 dogs trained to sleep with EEG electrodes.

To make the dogs more comfortable during their siestas, owners bring their dogs’ beds from home, which are placed in a protected room with white noise.

“Staff sit with them while they nap to make sure that they’re not trying to pull out or eat the electrodes or do anything that might hurt them,” Olby said.

When sleeping brain waves were compared with a dog’s cognitive testing, researchers found that dogs with greater dementia spent less time in deep and REM sleep, just as people do. The study was recently published in the journal Frontiers in Veterinary Science.

“Dogs that did worse on our memory tests had levels of REM sleep which were not as deep as they should be,” Olby said. “We found the same when it came to deep sleep.”

While no one knows the exact mechanism at work — either in people or in dogs — research like this study may help scientists better understand the process and find ways to treat it, Olby said.

“There’s a possibility we might be able to identify an early signature of change on the EEG that can tell us, ‘Hey, things are starting to slide.’ Because with a chronic neurodegenerative process, of course we’d love to be able to intervene sooner rather than later.”

In the meantime, there are medications for anxiety and melatonin for sleep that veterinarians can prescribe as a dog ages, Olby said. And as with people, diet and exercise appears to be a factor.

“There’s been some very nice studies showing diets that are enriched in flavonoids and antioxidants and medium-chain fatty acids could possibly slow the development of dementia in dogs,” she said. “It’s just like people — if you can eat a Mediterranean diet and do your exercise, you’re going to do better.”

Doggie dementia is a worrisome reality for many senior dogs. Research has found that by 11 or 12 years of age, 28% of dogs had mild and 10% had severe cognitive impairment. By the time the dogs reached age 15, the risk had risen to 68% for mild and 35% for severe cognitive impairment. A 2022 study found the odds of canine cognitive dysfunction increased by 52% with each year of age, Olby said.

Pet owners can look for signs that their dog’s mental functions are declining. According to Olby, vets use an acronym called DISHA-AL, which stands for disorientation, interaction changes, sleep/wake cycle alterations, house soiling; activity changes (increased or decreased); and anxiety and learning & memory.

“One of the earliest signs is you’ll start to see a little confusion just like you do with people, they suddenly start to make some mistakes and things you wouldn’t expect them to do. Very similar to us,” Olby said.

Dogs may also lose learned behaviors, or forget their house training and begin to have unintentional accidents around the house, she added.

“A classic problem is wandering around and getting lost under the table or something — they just can’t process the information and figure out where they are. Changes in sleep cycle, increased anxiety, all of these things are classic signs of dementia,” she said.

Don’t assume that is what is wrong with your dog, however. Just like in people, other health problems such as metabolic disease, urinary tract infections or even brain tumors can mimic classic signs of dementia.

“High blood pressure can make dogs anxious, for example,” Olby said, “so a vet needs to thoroughly check the dog to rule out disease.”

Don’t use sugar substitutes for weight loss, World Health Organization advises | CNN



CNN
 — 

Don’t use sugar substitutes if you are trying to lose weight, according to new guidance from the World Health Organization.

The global health body said a systematic review of the available evidence suggests the use of non-sugar sweeteners, or NSS, “does not confer any long-term benefit in reducing body fat in adults or children.”

“Replacing free sugars with non-sugar sweeteners does not help people control their weight long-term,” said Francesco Branca, director of WHO’s department of nutrition and food safety. “We did see a mild reduction of body weight in the short term, but it’s not going to be sustained.”

The guidance applies to all people except those with preexisting diabetes, Branca said. Why? Simply because none of the studies in the review included people with diabetes, and an assessment could not be made, he said.

The review also indicated that there might be “potential undesirable effects” from the long-term use of sugar substitutes such as a mildly increased risk of type 2 diabetes and cardiovascular diseases.

However, “this recommendation is not meant to comment on safety of consumption,” Branca said. “What this guideline says is that if we’re looking for reduction of obesity, weight control or risk of noncommunicable diseases, that is unfortunately something science been unable to demonstrate,” he said. “It’s not going to produce the positive health effects that some people might be looking for.”

Non-sugar sweeteners are widely used as an ingredient in prepackaged foods and beverages and are also sometimes added to food and drinks directly by consumers. WHO issued guidelines on sugar intake in 2015, recommending that adults and children reduce their daily intake of free sugars to less than 10% of their total energy intake. Following that recommendation, interest in sugar alternatives intensified, the review said.

“This new guideline is based on a thorough assessment of the latest scientific literature, and it emphasises that the use of artificial sweeteners is not a good strategy for achieving weight loss by reducing dietary energy intake,” said nutrition researcher Ian Johnson, emeritus fellow at Quadram Institute Bioscience, formerly the Institute of Food Research, in Norwich, United Kingdom.

“However, this should not be interpreted as an indication that sugar intake has no relevance to weight-control,” Johnson said in a statement.

Instead, one should cut back on using sugar-sweetened drinks, and try to use “raw or lightly processed fruit as a source of sweetness,” Johnson added.

Dr. Keith Ayoob, scientific adviser for the Calorie Control Council, an international association representing the low-calorie food and beverage industry, told CNN via email the WHO’s “insistence on focusing only on prevention of unhealthy ‎weight gain and non-communicable diseases is at the very least, misguided.”

Robert Rankin, president of the Calorie Control Council, said “low- and no-calorie sweeteners are a critical tool that can help consumers manage body weight and reduce the risk of non-communicable diseases.”

The guidance is meant for government health organizations in countries who may wish to use the scientific analysis to implement policy changes for their citizens, Branca said.

“That will likely depend on the way that which sweeteners are consumed in a specific country,” he said. “For example, in a country where consumption patterns are high, those countries might decide to take action in a way or another.”

A total of 283 studies were included in the review. Both randomized controlled trials, considered the gold standard of research, and observational studies were included. Observational studies can only show an association, not direct cause and effect.

Results from randomized trials found the use of non-sugar sweeteners had a “low” impact on reducing body weight and calorie intake when compared with sugar, and no change in Intermediate markers of diabetes such as glucose and insulin, according to the report.

Observational studies also found a low impact on body weight and fat tissue, but no change in calorie intake. However, those studies found a low increase in risk for type 2 diabetes, high blood pressure, stroke, heart disease and death from heart disease, the report noted. A very low risk was also found for bladder cancer and an early death from any cause.

WHO said that the recommendation was “conditional” because the identified link between sweeteners and disease outcomes might be confounded by complicated patterns of sweetener use and the characteristics of the study participants.

In an emailed statement, the International Sweeteners Association, an industry assocation, said “it is a disservice to not recognise the public health benefits of low/no calorie sweeteners and is disappointed that the WHO’s conclusions are largely based on low certainty evidence from observational studies, which are at high risk of reverse causality.”

However, observational studies that follow people over time are important, Branca said. “To show that overweight people can reduce their body weight requires a long-term study. And we’re not seeing that impact from the research we have.”

The recommendation included low or no calorie synthetic sweeteners and natural extracts, which may or may not be chemically modified, such as acesulfame K, aspartame, advantame, cyclamates, neotame, saccharin, sucralose, stevia and stevia derivatives and monkfruit, the report said.

“Stevia and monkfruit are newer sweeteners so so there’s less published research in the scientific literature,” Branca said. “However they probably work in the body with a similar physiological mechanism as other sweeteners. We cannot say they are different from the others based on the data we have — they play the same role.”

Many people consider stevia products to be more “natural,” since they are derived from the stevia plant. Some natural and artificial sweeteners add bulking sugars to their products to cut their sweetness and add bulk to the product for baking.

A recent study by researchers at the US-based Cleveland Clinic found erythritol — used to add bulk or sweeten stevia, monkfruit and keto reduced-sugar products — was linked to blood clotting, stroke, heart attack and early death.

People with existing risk factors for heart disease, such as diabetes, were twice as likely to experience a heart attack or stroke if they had the highest levels of erythritol in their blood, the study found.

Just as many people have learned to eat and cook without salt, they can learn to reduce their dependence on free sugars and non-nutritive sweetners, Branca said.

“We need to target children in early life,” he said. “For example, why do parents typically use sweeteners as a reward for children and after almost every meal? We need to recommend to parents to avoid building that sweetness Interest in young children — that’s a very important action to take.”

Even if you are a true sugar “addict,” the good news is that you can tame your sweet tooth, registered dietitian Lisa Drayer said in an article for CNN. She provides the following steps:

Train your taste buds. If you gradually cut back on sugar — including artificial sweeteners — and include more protein and fiber-rich foods in your diet, that can help you crave less sugar, Drayer said.

“When we consume protein and fiber, it slows the rise in blood sugar if we consume it with a sugar-containing food. It can help satisfy us and help us reduce our sugar intake as well,” she said in a previous interview.

Choose no-sugar-added foods and avoid all sugar-sweetened drinks. For example, choose whole-grain cereal or Greek yogurt with no sweeteners. The sugar-sweetened drinks to take off your grocery list should include sodas, energy drinks, sports drinks and fruit punch. Choose water instead.

“If you like sweet carbonated beverages, add a splash of cranberry or orange juice to seltzer or try flavored seltzers. You can also flavor your own waters with fruit slices for natural sweetness or try herbal fruit teas,” Drayer said.

Drink coffee and tea with no or fewer sugars. Be careful at coffee shops, Drayer suggested. All those lattes and flavored coffees can have as much sugar as a can of soda, or more.

Enjoy fruit for dessert. Try cinnamon baked apples, berries or grilled peaches instead of cookies, cake, ice cream, pastries and other sweet treats, Drayer said.

Watch for stealth sugars. Added sugars are often present in foods that you might not think of as “sweet,” like sauces, breads, condiments and salad dressings, Drayer said.

“Pre-packaged sauces — like ketchup, BBQ sauce and tomato sauce — tend to be some of the biggest offenders of hidden added sugars in the diet,” Kristi King, senior pediatric dietitian at Texas Children’s Hospital and a national spokesperson for the Academy of Nutrition and Dietetics, told Drayer in a prior interview.

Check nutrition facts labels. All foods and beverages must list the amount and kind of sugar on the label.

Added sugars can go by other names such as “agave, brown sugar, corn sweetener, corn syrup, dextrose, evaporated cane juice, fructose, fruit juice concentrate, fruit nectar, glucose, high-fructose corn syrup, honey, invert sugar, lactose, malt syrup, maltose, molasses, maple syrups, raw sugar, sucrose, trehalose and turbinado sugar,” Drayer said.

The higher up these added sugars are on the ingredients list, the greater the amount of added sugar in the product, she said.
