Q&A: Long COVID symptoms, management, and where we’re headed

Article Type

Tue, 05/24/2022 - 16:23

Long COVID continues to be a moving target – continuously evolving and still surprising doctors and patients who have sometimes incapacitating long-term symptoms.

Little about the disorder seems predictable at this point. People can have long COVID after asymptomatic, mild, or severe COVID-19, for example. And when a person gets long COVID – also known as long-haul COVID – symptoms can vary widely.

To address all the uncertainty, the New York State Department of Health gathered experts in primary care, pediatrics, physical medicine, rehabilitation, and pulmonology to answer some pressing questions.

New York in 2020 was the first epicenter of the pandemic in the United States, making it also the center of the long COVID epidemic, says Emily Lutterloh, MD, director of the Division of Epidemiology at the New York State Department of Health.
 

What do you do when you’re seeing a patient with long COVID for the first time?

The first exam varies because there are so many different ways long COVID presents itself, says Benjamin Abramoff, MD, a physical medicine and rehabilitation specialist at Penn Medicine in Philadelphia.

I’ve now been seriously ill with #LongCovid for 11 months. I was never hospitalized. I didn’t even have a “mild” covid case. Instead, I developed Long Covid from an asymptomatic infection.

I’m far from unique. Up to 1/5 of asymptomatic patients go on to have long-term symptoms.

Assessing their previous and current care also helps to direct their ongoing management, says Zijian Chen, MD, medical director of the Center for Post-COVID Care at Mount Sinai Health System in New York.
 

Can vaccination help people with long COVID?

Anything that we can do to help prevent people from being critically ill or being hospitalized with COVID-19 is helpful to prevent long COVID, says Dr. Abramoff, who is also director of the long COVID clinic at the University of Pennsylvania, Philadelphia.

“So that’s something I always discuss with patients. In some research, sometimes patients do feel better after the vaccine,” he says.
 

What kind of therapies do you find helpful for your patients?

Rehabilitation is a key part of recovery from long COVID, Dr. Abramoff says. “It is very important to make this very patient-specific.”

“We have patients that are working. They’re already going to the gym in some cases but don’t feel like they have the same endurance,” he says. “And then we have patients who are so crippled by their fatigue that they can’t get out of bed.”

An exercise program can help people who have long COVID.

“There’s a big role for therapy services in the recovery of these patients,” says John Baratta, MD, of the department of physical medicine and rehabilitation at the University of North Carolina at Chapel Hill.

But the limited number of long COVID clinics can mean some people are unable to get to therapists trained on the needs of patients with lingering COVID symptoms. Educating community physical and occupational therapists is one solution.
 

 

 

How long does it take for people with long COVID to recover and get back to 100% if they can?

Specific numbers aren’t really available, Dr. Baratta says.

“But I can tell you the general trend that I see is that a lot of patients have a gradual improvement of symptoms. The slow but steady improvement with time may be the body’s natural healing process, a result of medical interventions, or both.”

It can help to reassure people with long COVID that they will not be discharged from care until they feel they’ve maximized their health, says Sharagim Kemp, DO, medical director of the COVID Recovery Program for Nuvance Health, a health system in New York and Connecticut.

It’s essential to set realistic recovery expectations and tell patients that not everyone will return to 100% of their pre-COVID functioning, she says.

“Once we are able to help them reset their expectations, there’s almost an accelerated recovery because they are not putting that pressure on themselves anymore,” Dr. Kemp says.
 

What are the most common symptoms you’re seeing in long COVID?

It’s helpful to think of long COVID as a very broad umbrella term, Dr. Abramoff says.

Echoing what many others have observed, fatigue, cognitive dysfunction or “brain fog,“ and shortness of breath or troubled breathing appear to be the most common symptoms, he says.

Some reported vague symptoms, Dr. Kemp says.

People may go to the doctor “not even realizing that they had COVID. That’s one of the important points here – to have a high index of suspicion for patients who come in with multiple symptoms,” she says.

For this reason, patients can report symptoms that don’t necessarily fit into any specialty, says Sarah J. Ryan, MD, an internal medicine doctor at Columbia University Irving Medical Center in New York. People say they are “just not themselves” or they are tired after their COVID-19 recovery.
 

Is there a connection between severe COVID cases and severe long COVID?

“It’s not like that at all. I would say that more than 80% of the patients that we see had mild to moderate illness and they were not hospitalized,” Dr. Baratta says.

Long COVID is a bit different in children and teenagers, says Ixsy Ramirez, MD, a pediatric pulmonologist at University of Michigan Health, Ann Arbor. Most patients in the long COVID clinic at the University of Michigan were previously healthy, and not children with asthma or other lung conditions as one might expect. In fact, many are student athletes, or were before they had long COVID.

In this population, shortness of breath is most common, followed by chest pain and fatigue. Unfortunately, the symptoms are so serious for many kids that their performance is limited, even if they can return to competitive play.
 

Are there defined criteria you use to diagnose long COVID? How do you give someone a diagnosis?

That’s an ever-evolving question, Dr. Kemp says. The generally accepted definition centers on persistent or new symptoms 4 weeks or more after the original COVID-19 illness, but there are exceptions.

Researchers are working on lab tests to help confirm the diagnosis. But without a definitive blood biomarker, getting to the diagnosis requires “some thorough detective work,” Dr. Ryan says.
 

Do you bring in mental health providers to help with treatment?

“We focus on mental health quite a bit actually,” says, Dr. Chen, cofounder of his institution’s COVID recovery clinic. Mount Sinai offers one-on-one and group mental health services, for example.

“Personally, I’ve seen patients that I did not expect to have such severe mental health changes” with long COVID.
 

One of the most powerful accounts and testimonies I have seen on what most #LongCovid patients experience when interacting with their doctors.

Examples include severe depression, cases of acute psychosis, hallucinations, and other problems “that are really unexpected after a viral illness.”

Stony Brook University Hospital in New York has a long COVID clinic staffed by multiple primary care doctors who do exams and refer patients to services. A bonus of offering psychological services to all post-COVID patients is doctors get a more complete picture of each person and a better understanding of what they are going through, says Abigail Chua, MD, a pulmonologist at Stony Brook.

Some empathy is essential, Dr. Baratta says. “It’s important to recognize that a lot of these patients present with a sense of grief or loss for their prior life.”
 

What does the future hold?

A simple test to diagnose long COVID, combined with an effective treatment that helps people feel better within a week, would be ideal, Dr. Abramoff says.

“That would be lovely. But you know, we’re just not at that point.”

And it would be helpful to start identifying subtypes of long COVID so diagnosis and treatment can be more targeted, Dr. Abramoff says. Otherwise, “It’s going to be a very challenging approach to try to treat all of our patients with long COVID symptoms the same way.”

Good clinical trials likewise are needed to address all the subtleties of long COVID.

A number of long COVID centers are collaborating on research to find out more, Dr. Chen says. Actions include setting up a bank of tissue samples from people with long COVID so researchers can continue to figure out the condition.

One goal, Dr. Chen says, would be the ability to treat long COVID rather than just its symptoms.

Long COVID emphasizes the need to prevent people from getting COVID in the first place, Dr. Ramirez says. This will continue to be important, particularly when some people dismiss the seriousness of COVID, comparing it to a cold if they get it. That attitude discounts the large number of people who unfortunately go on to develop long-term, often debilitating, symptoms.

Referrals to gender clinics in Sweden drop after media coverage

Article Type
Changed
Mon, 02/07/2022 - 15:23

Media coverage of transgender health care judged to be “negative” was associated with a drop of around 30% in referral rates to gender identity clinics in Sweden among young people under age 19, a new study indicates.

Malin Indremo, MS, from the department of neuroscience, Uppsala (Sweden) University, and colleagues explored the effect of the documentaries, “The Trans Train and Teenage Girls,” which they explain was a “Swedish public service television show” representing “investigative journalism.” The two-part documentary series was aired in Sweden in April 2019 and October 2019, respectively, and is now available in English on YouTube.

In their article, published online in JAMA Network Open, the authors said they consider “The Trans Train” programs to be “negative” media coverage because the “documentaries addressed the distinct increase among adolescents referred to gender identity clinics in recent years. Two young adults who regretted their transition and parents of transgender individuals who questioned the clinics’ assessments of their children were interviewed, and concerns were raised about whether gender-confirming treatments are based on sufficient scientific evidence.”

The programs, they suggest, may have influenced and jeopardized young transgender individuals’ access to transgender-specific health care.

Stella O’Malley, a U.K.-based psychotherapist specializing in transgender care and executive director of Genspect, an international organization that provides support to the parents of young people who are questioning their gender, expressed her disappointment with the study’s conclusions.

“I’m really surprised and disappointed that the researchers believe that negative coverage is the reason for a drop in referrals when it is more accurate to say that the information provided by ‘The Trans Train’ documentaries was concerning and suggests that further critical analysis and a review needs to be carried out on the clinics in question,” she said in an interview.

Ms. O’Malley herself made a documentary for Channel 4 in the United Kingdom, broadcast in 2018, called: “Trans Kids: It’s Time to Talk.”
 

Rapidly increasing numbers of youth, especially girls, question gender

As Ms. Indremo and coauthors explained – and as has been widely reported by this news organization – “the number of referrals to gender identity clinics have rapidly increased worldwide” in recent years, and this “has been especially prominent in adolescents and young adults.”

In addition, they acknowledged, “there has been a shift in gender ratio, with a preponderance toward individuals who were assigned female at birth (AFAB).”

This was the topic of “The Trans Train” programs, and in fact, following their broadcast, Ms. Indremo and colleagues noted that “an intense debate in national media [in Sweden] arose from the documentaries.”

Their research aimed to explore the association between both “positive” and “negative” media coverage and the number of referrals to gender identity clinics for young people (under aged 19) respectively. Data from the six gender clinics in Sweden were included between January 2017 and December 2019.

In the period studied, the clinics received 1,784 referrals, including 613 referrals in 2017, 663 referrals in 2018, and 508 referrals in 2019.

From the age-specific data that included 1,674 referrals, 359 individuals (21.4%) were younger than 13 years and 1,315 individuals (78.6%) were aged 13-18 years. From the assigned sex-specific data that included 1,435 referrals, 1,034 individuals (72.1%) were AFAB and 401 individuals (27.9%) were assigned male at birth (AMAB). Information on sex assigned at birth was lacking from one clinic, which was excluded from the analysis.

When they examined data for the 3 months following the airing of the first part of “The Trans Train” documentary series (in April 2019), they found that referrals to gender clinics fell by 25.4% overall, compared with the 3 months before part 1 was screened. Specifically, they fell by 25.3% for young people aged 13-18 years and by 32.2% for those born female.

In the extended analyses of 6 months following part 1, a decrease of total referrals by 30.7% was observed, while referrals for AFAB individuals decreased by 37.4% and referrals for individuals aged 13-18 years decreased by 27.7%. A decrease of referrals by 41.7% for children aged younger than 13 years was observed in the 6-month analysis, as well as a decrease of 8.2% among AMAB individuals.

“The Trans Train” documentaries, Ms. Indremo and colleagues said, “were criticized for being negatively biased and giving an oversimplified picture of transgender health care.”
 

 

 

Did the nature of the trans train documentaries influence referrals?

In an invited commentary published in JAMA Network Open, Ken C. Pang, PhD, from the Murdoch Children’s Research Institute, Melbourne, and colleagues noted: “Although the mechanisms underlying this decrease [in referrals] were not formally explored in their study, the authors reasonably speculated that both parents and referring health professionals may have been less likely to support a child or adolescent’s attendance at a specialist pediatric gender clinic following the documentaries.”

Dr. Pang and colleagues went on to say it is “the ... responsibility of media organizations in ensuring that stories depicting health care for transgender and gender diverse (TGD) young people are fair, balanced, nuanced, and accurate.”

Often, media reports have “fallen short of these standards and lacked the voices of TGD young people who have benefited from gender-affirming care or the perspectives of health professionals with expertise in providing such care,” they added.

“For example, some [media reports] have suggested that the growing number of referrals to such clinics is not owing to greater awareness of gender diversity and empowerment of TGD young people but is instead being driven by other factors such as peer influence, while others have warned that the use of gender-affirming hormonal interventions in TGD young people represents an undue risk,” they continue.

Ms. Indremo and colleagues didn’t see any drop-in referrals after the second part of the series, aired in October 2019, but they say this was likely because referrals were “already lowered” by the airing of the first part of the documentaries.

Nor did they see an increase in referrals following what they say was a “positive” media event in the form of a story about a professional Swedish handball player who announced the decision to quit his career to seek care for gender dysphoria.

“One may assume that a single news event is not significant enough to influence referral counts,” they suggested, noting also that Sweden represents “a society where there is already a relatively high level of awareness of gender identity issues.”

“Our results point to a differential association of media attention depending on the tone of the media content,” they observed.

Dr. Pang and coauthors noted it would be “helpful to examine whether similar media coverage in other countries has been associated with similar decreases in referral numbers and whether particular types of media stories are more prone to having this association.”
 

Parents and doctors debate treatment of gender dysphoria

In Sweden, custodians’ permission as well as custodians’ help is needed for minors to access care for gender dysphoria, said Ms. Indremo and coauthors. “It is possible that the content of the documentaries contributed to a higher custodian barrier to having their children referred for assessment, believing it may not be in the best interest of their child. This would highly impact young transgender individuals’ possibilities to access care.” 

They also acknowledge that health care practitioners who refer young people to specialist clinics might also have been influenced by the documentaries, noting “some commentators argued that all treatments for gender dysphoria be stopped, and that ‘all health care given at the gender identity clinics was an experiment lacking scientific basis.’ ”

In April 2021, Angela Sämfjord, MD, child and adolescent psychiatrist at Sahlgrenska University Hospital, Gothenburg, Sweden, who started a child and adolescent clinic – the Lundstrom Gender Clinic – told this news organization she had reevaluated her approach even prior to “The Trans Train” documentaries and had resigned in 2018 because of her own fears about the lack of evidence for hormonal and surgical treatments of youth with gender dysphoria.

Following the debate that ensued after the airing of “The Trans Train” programs, the Swedish National Board of Health and Welfare published new recommendations in March 2021, which reflected a significant change in direction for the evaluation of gender dysphoria in minors, emphasizing the requirement for a thorough mental health assessment.

And in May 2021, Karolinska Children’s Hospital, which houses one of the leading gender identity clinics in Sweden, announced it would stop the routine medical treatment of children with gender dysphoria under the age of 18, which meant a total ban on the prescribing of puberty blockers and cross-sex hormones to minors. Such treatment could henceforth only be carried out within the setting of a clinical trial approved by the EPM (Ethical Review Agency/Swedish Institutional Review Board), it said.

The remaining five gender identity clinics in Sweden decided upon their own rules, but in general, they have become much more cautious regarding medical treatment of minors within the past year. Also, there is a desire in Sweden to reduce the number of gender identity clinics for minors from the current six to perhaps a maximum of three nationwide.

However, neither Ms. Indremo and colleagues nor Dr. Pang and colleagues mentioned the subsequent change to the Swedish NBHW recommendations on evaluation of gender dysphoria in minors in JAMA articles.

New NBHW recommendations about medical treatment of gender dysphoria with puberty blockers and cross-sex hormones for minors were due to be issued in 2021 but have been delayed.
 

 

 

Debate in other countries

Sweden is not alone in discussing this issue. In 2020, Finland became the first country in the world to issue new guidelines that concluded there is a lack of quality evidence to support the use of hormonal interventions in adolescents with gender dysphoria.

This issue has been hotly debated in the United Kingdom – not least with the Keira Bell court case and two National Institute for Health and Clinical Excellence evidence reviews concluding there is a lack of data to support the use of puberty-blocking agents and “cross-sex” hormones in youth with gender dysphoria.

And a number of U.S. states are attempting to outlaw the medical and surgical treatment of gender dysphoria in minors. Even health care professionals who have been treating young people with gender dysphoria for years – some of whom are transgender themselves – have started to speak out and are questioning what they call “sloppy care” given to many such youth.

Indeed, a recent survey shows that detransitioners – individuals who suffer from gender dysphoria, transition to the opposite sex but then regret their decision and detransition – are getting short shrift when it comes to care, with over half of the 100 surveyed saying they feel they did not receive adequate evaluation from a doctor or mental health professional before starting to transition.

And new draft standards of care for treating people with gender dysphoria by the World Professional Association for Transgender Health have drawn criticism from experts.
 

‘First do no harm’

In their conclusion, Dr. Pang and coauthors said that, with respect to the media coverage of young people with gender dysphoria, “who are, after all, one of the most vulnerable subgroups within our society, perhaps our media should recall one of the core tenets of health care and ensure their stories ‘first, do no harm.’”

However, in a commentary recently published in Child and Adolescent Mental Health, Alison Clayton, MBBS, from the University of Melbourne, and coauthors again pointed out that evidence reviews of the use of puberty blockers in young people with gender dysphoria show “there is very low certainty of the benefits of puberty blockers, an unknown risk of harm, and there is need for more rigorous research.”

“The clinically prudent thing to do, if we aim to ‘first, do no harm,’ is to proceed with extreme caution, especially given the rapidly rising case numbers and novel gender dysphoria presentations,” Clayton and colleagues concluded.

Ms. Indremo and coauthors reported no relevant financial relationships. Dr. Pang reported being a member of the Australian Professional Association for Trans Health and its research committee. One commentary coauthor has reported being a member of WPATH.

Media coverage of transgender health care judged to be “negative” was associated with a drop of around 30% in referral rates to gender identity clinics in Sweden among young people under age 19, a new study indicates.

Malin Indremo, MS, from the department of neuroscience, Uppsala (Sweden) University, and colleagues explored the effect of the documentaries, “The Trans Train and Teenage Girls,” which they explain was a “Swedish public service television show” representing “investigative journalism.” The two-part documentary series was aired in Sweden in April 2019 and October 2019, respectively, and is now available in English on YouTube.

In their article, published online in JAMA Network Open, the authors said they consider “The Trans Train” programs to be “negative” media coverage because the “documentaries addressed the distinct increase among adolescents referred to gender identity clinics in recent years. Two young adults who regretted their transition and parents of transgender individuals who questioned the clinics’ assessments of their children were interviewed, and concerns were raised about whether gender-confirming treatments are based on sufficient scientific evidence.”

The programs, they suggest, may have influenced and jeopardized young transgender individuals’ access to transgender-specific health care.

Stella O’Malley, a U.K.-based psychotherapist specializing in transgender care and executive director of Genspect, an international organization that provides support to the parents of young people who are questioning their gender, expressed her disappointment with the study’s conclusions.

“I’m really surprised and disappointed that the researchers believe that negative coverage is the reason for a drop in referrals when it is more accurate to say that the information provided by ‘The Trans Train’ documentaries was concerning and suggests that further critical analysis and a review needs to be carried out on the clinics in question,” she said in an interview.

Ms. O’Malley herself made a documentary for Channel 4 in the United Kingdom, broadcast in 2018, called: “Trans Kids: It’s Time to Talk.”
 

Rapidly increasing numbers of youth, especially girls, question gender

As Ms. Indremo and coauthors explained – and as has been widely reported by this news organization – “the number of referrals to gender identity clinics have rapidly increased worldwide” in recent years, and this “has been especially prominent in adolescents and young adults.”

In addition, they acknowledged, “there has been a shift in gender ratio, with a preponderance toward individuals who were assigned female at birth (AFAB).”

This was the topic of “The Trans Train” programs, and in fact, following their broadcast, Ms. Indremo and colleagues noted that “an intense debate in national media [in Sweden] arose from the documentaries.”

Their research aimed to explore the association between both “positive” and “negative” media coverage and the number of referrals to gender identity clinics for young people (under aged 19) respectively. Data from the six gender clinics in Sweden were included between January 2017 and December 2019.

In the period studied, the clinics received 1,784 referrals, including 613 referrals in 2017, 663 referrals in 2018, and 508 referrals in 2019.

From the age-specific data that included 1,674 referrals, 359 individuals (21.4%) were younger than 13 years and 1,315 individuals (78.6%) were aged 13-18 years. From the assigned sex-specific data that included 1,435 referrals, 1,034 individuals (72.1%) were AFAB and 401 individuals (27.9%) were assigned male at birth (AMAB). Information on sex assigned at birth was lacking from one clinic, which was excluded from the analysis.

When they examined data for the 3 months following the airing of the first part of “The Trans Train” documentary series (in April 2019), they found that referrals to gender clinics fell by 25.4% overall, compared with the 3 months before part 1 was screened.

A decrease of referrals by 41.7% for children aged younger than 13 years was observed in the 6-month analysis, as well as a decrease of 8.2% among AMAB individuals.

Does using A1c to diagnose diabetes miss some patients?

Article Type
Changed
Tue, 05/03/2022 - 15:02

The introduction of hemoglobin A1c as an option for diagnosing type 2 diabetes over a decade ago may have resulted in underdiagnosis, new research indicates.

In 2011, the World Health Organization advised that A1c measurement, with a cutoff value of 6.5%, could be used to diagnose diabetes. The American Diabetes Association had issued similar guidance in 2010.

Prior to that time, the less-convenient 2-hour oral glucose tolerance test (OGTT) and fasting blood glucose (FBG) were the only recommended tests. While WHO made no recommendations for interpreting values below 6.5%, the ADA designated 5.7%-6.4% as prediabetes.

The new study, published online in The Lancet Regional Health–Europe, showed that the incidence of type 2 diabetes in Denmark had been increasing prior to the 2012 adoption of A1c as a diagnostic option but declined thereafter. And all-cause mortality among people with type 2 diabetes, which had been dropping, began to increase after that time.  

“Our findings suggest that fewer patients have been diagnosed with [type 2 diabetes] since A1c testing was introduced as a convenient diagnostic option. We may thus be missing a group with borderline increased A1c values that is still at high metabolic and cardiovascular risk,” Jakob S. Knudsen, MD, of the department of clinical epidemiology, Aarhus (Denmark) University Hospital, and colleagues wrote.

Therefore, Dr. Knudsen said in an interview, clinicians should “consider testing with FBG or OGTT when presented with borderline A1c values.”

The reason for the increase in mortality after incident type 2 diabetes diagnosis, he said, “is that the patients who would have reduced the average mortality are no longer diagnosed...This does not reflect that we are treating already diagnosed patients any worse, rather some patients are not diagnosed.”



But M. Sue Kirkman, MD, emeritus professor of medicine at the University of North Carolina at Chapel Hill, who was part of the writing group for the 2010 ADA guidelines, isn’t convinced.

“This is an interesting paper, but it is a bit hard to believe that a change in WHO recommendations would have such a large and almost immediate impact on incidence and mortality. It seems likely that ... factors [other] than just the changes in recommendations for the diagnostic test account for these findings,” she said.

Dr. Kirkman pointed to new data just out from the Centers for Disease Control and Prevention on Jan. 26 that don›t show evidence of a higher proportion of people in the United States who have undiagnosed diabetes, “which would be expected if more cases were being ‘missed’ by A1c.”

She added that the CDC incidence data “show a continuing steady rate of decline in incidence that began in 2008, before any organizations recommended using A1c to screen for or diagnose diabetes.” Moreover, “there is evidence that type 2 diabetes incidence has fallen or plateaued in many countries since 2006, well before the WHO recommendation, with most of the studies from developed countries.”

But Dr. Knudsen also cited other data, including a study that showed a drop or stabilization in diagnosed diabetes incidence in high-income countries since 2010.

“That study concluded that the reasons for the declines in the incidence of diagnosed diabetes warrant further investigation with appropriate data sources, which was a main objective of our study,” wrote Dr. Knudsen and coauthors.

Dr. Knudsen said in an interview: “We are not the first to make the point that this sudden change is related to A1c introduction...but we are the first to have the data to clearly show that is the case.”

 

 

Diabetes incidence dropped but mortality rose after 2010

The population-based longitudinal study used four Danish medical databases and included 415,553 patients treated for type 2 diabetes for the first time from 1995-2018 and 2,060,279 matched comparators not treated for diabetes.

From 1995 until the 2012 introduction of A1c as a diagnostic option, the annual standardized incidence rates of type 2 diabetes more than doubled, from 193 per 100,000 population to 396 per 100,000 population, at a rate of 4.1% per year.

But from 2011 to 2018, the annual standardized incidence rate declined by 36%, to 253 per 100,000 population, a 5.7% annualized decrease.

The increase prior to 2011 occurred in both men and women and in all age groups, while the subsequent decline was seen primarily in the older age groups. The all-cause mortality risk within the first year after diabetes diagnosis was higher than subsequent 1-year mortality risks and not different between men and women.

From the periods 1995-1997 to 2010-2012, the adjusted mortality rate among those with type 2 diabetes decreased by 44%, from 72 deaths per 1000 person-years to 40 deaths per 1000 person-years (adjusted mortality rate ratio, 0.55). After that low level in 2010-2012, mortality increased by 27% to 48 per 1000 person-years (adjusted mortality rate ratio 0.69, compared with 1995-1997).  

The reversed mortality trend after 2010-2012 was caused almost entirely by the increase in the first year after diabetes diagnosis, Dr. Knudsen and colleagues noted.

According to Dr. Kirkman, “A1c is strongly predictive of complications and mortality. That plus its ease of use and the fact that more people may be screened mean it’s still a good option. But for any of these tests, people who are slightly below the cut-point should not be considered normal or low risk.”

Indeed, Dr. Knudsen and colleagues said, “these findings may have implications for clinical practice and suggest that a more multifactorial view of metabolic risk is needed.”

Dr. Knudsen and Dr. Kirkman have reported no relevant financial relationships.

The introduction of hemoglobin A1c as an option for diagnosing type 2 diabetes over a decade ago may have resulted in underdiagnosis, new research indicates.

In 2011, the World Health Organization advised that A1c measurement, with a cutoff value of 6.5%, could be used to diagnose diabetes. The American Diabetes Association had issued similar guidance in 2010.

Prior to that time, the less-convenient 2-hour oral glucose tolerance test (OGTT) and fasting blood glucose (FBG) were the only recommended tests. While WHO made no recommendations for interpreting values below 6.5%, the ADA designated 5.7%-6.4% as prediabetes.

The new study, published online in The Lancet Regional Health–Europe, showed that the incidence of type 2 diabetes in Denmark had been increasing prior to the 2012 adoption of A1c as a diagnostic option but declined thereafter. And all-cause mortality among people with type 2 diabetes, which had been dropping, began to increase after that time.  

“Our findings suggest that fewer patients have been diagnosed with [type 2 diabetes] since A1c testing was introduced as a convenient diagnostic option. We may thus be missing a group with borderline increased A1c values that is still at high metabolic and cardiovascular risk,” Jakob S. Knudsen, MD, of the department of clinical epidemiology, Aarhus (Denmark) University Hospital, and colleagues wrote.

Therefore, Dr. Knudsen said in an interview, clinicians should “consider testing with FBG or OGTT when presented with borderline A1c values.”

The reason for the increase in mortality after incident type 2 diabetes diagnosis, he said, “is that the patients who would have reduced the average mortality are no longer diagnosed...This does not reflect that we are treating already diagnosed patients any worse, rather some patients are not diagnosed.”

Dietary fat tied to better cognition in older adults

Dietary intake of polyunsaturated fatty acids (PUFA), particularly omega 6, is associated with improved cognitive function in older adults, new research suggests.

The study provides important “pieces of the puzzle” of the diet and cognition connection, but the results aren’t “ready for prime time,” study investigator Roger S. McIntyre, MD, professor of psychiatry and pharmacology, University of Toronto, said in an interview.

“I don’t think we’re there yet when it comes to recommending supplementation to the general public,” said Dr. McIntyre, adding a larger “more compelling study” is needed.

The study was published online Jan. 14 in The American Journal of Geriatric Psychiatry.
 

Clinically meaningful?

Research shows that 25%-50% of community-dwelling adults aged 65-85 years have some cognitive impairment. Other evidence indicates cognition is affected by dietary fat intake.

Many lines of research show that alterations in lipid homeostasis can cause brain dysfunction, said Dr. McIntyre. “This shouldn’t surprise us because our brain is made up of protein, water, and fat.”

This new analysis used combined data from the 2011-2012 and 2013-2014 cycles of the National Health and Nutrition Examination Survey (NHANES), a series of ongoing cross-sectional surveys conducted by the Centers for Disease Control and Prevention. The data are collected in two phases, an in-home face-to-face interview and a physical examination.

Researchers obtained dietary intake information through two 24-hour dietary recall interviews. Dietary information included total energy (kcal/d), intakes in grams per day (g/d) of total fat, saturated fatty acid (SFAT), monounsaturated fatty acid (MUFA), PUFA, total omega-3 and total omega-6 fatty acids, and milligrams per day (mg/d) of cholesterol.

For cognitive function, the researchers used total and delayed recall scores of the Consortium to Establish a Registry for Alzheimer’s Disease (CERAD), the animal fluency test, and the digit symbol substitution test (DSST).

The study included 2,253 adults aged 60 years and older (mean age, 69.4 years) and 51% were non-Hispanic White individuals.

After adjustment for age, sex, race/ethnicity, educational attainment, smoking status, alcohol consumption, income, and total energy, dietary intake of PUFA and omega-6 fatty acid was positively associated with DSST.

The DSST score increased about 0.06 standard deviation (SD) (about 1 score) with each SD increase in these fatty acids (8.8 g/d for PUFA and 7.9 g/d for omega-6) (P values were .02 for PUFA and .01 for omega-6).

However, it’s unclear what an improvement of 1 DSST score means clinically, said Dr. McIntyre. “The P value is significant, but how does that translate? Does this mean a person can now think more clearly or function better?”
 

 

 

‘Million dollar question’ remains unanswered

The fact that omega-6, considered neuroinflammatory, was associated with improved DSST score illustrates the complexity of this field, said Dr. McIntyre.

“We’re learning that when it comes to inflammation, many of the molecules in our brain that are implicated as anti-inflammatory can also be pro-inflammatory, so bad guys can be good guys and good guys can be bad guys.”

It speaks to the notion of homeostasis, he added. “Just like a seesaw; when you push this part down, that part goes up.”

The analysis showed the animal fluency score increased about 0.05 SD (around 0.3 score) with each SD (1.1 g/d) increase in dietary intake of omega-3.

There were no significant associations between other dietary fat intake and cognitive performance.

The researchers investigated the role of oxidative stress and antioxidant biomarkers (gamma glutamyl transpeptidase [GGT], bilirubin, uric acid, and vitamin D).

Cells produce oxidative radicals that are normally “mopped up” by our “innate antioxidant capability,” said Dr. McIntyre. “But in states of cognitive impairment, these oxidative stress markers accumulate and they exceed what the normal innate response is able to manage.”

The study showed GGT levels decreased with increased PUFA and omega-6 fatty acid intakes; levels of bilirubin decreased with increase in most dietary fat intakes; uric acid levels decreased with MUFA intake and omega-6/omega-3 ratio; and vitamin D levels increased with omega-3 fatty acid intake but decreased with SFAT intake.

Causal mediation analysis showed the association between dietary intake of fatty acids and DSST performance was partially mediated by GGT levels. However, Dr. McIntyre emphasized that this does not prove causality.

“The million dollar question is, is this the sole explanation for the association? In other words, is it the oxidative stress that caused the cognitive impairment and therefore correcting it improved it, or is it the case that oxidative stress is a proxy of other activities that are also taking place?”
 

 

 

A ‘plausible’ link

In an editorial, Candida Rebello, PhD, of the department of integrated physiology and molecular medicine at Pennington Biomedical Research Center, Baton Rouge, La., said the finding that omega-3 and omega-6 fatty acids are positively associated with cognition in older adults makes some sense.

She noted that aging is associated with an overt inflammatory phenotype, and evidence shows these fatty acids are precursors for bioactive molecules that play a role in self-limiting the acute inflammatory response.

Dr. Rebello said the positive association of omega-6 fatty acid with cognition shown in this study contrasts with the “common belief” that increasing dietary intake of these fatty acids enhances inflammation, but agreed the association is “plausible.”

She said it’s “essential” to determine “the underlying mechanisms that regulate the diverse features of inflammation and sort out the processes that protect from neuronal damage and those that contribute towards it.”

She noted the ratio of omega-6 to omega-3 is about 15:1 in the present day Western diet, as opposed to a 1:1 ratio in diets of the past. Omega-3 fatty acids are found in fish oil supplements and fatty fish like mackerel and salmon, while cereal, grains, and vegetable oil are sources of omega-6.

Attaining a measure of balance of fatty acids in the diet may be a “prudent approach,” said Dr. Rebello. “Substituting some meat entrées with fatty fish and polyunsaturated vegetable oils with monounsaturated fats such as olive oil are small changes that are likely to garner adherence.”

Dr. Rebello noted that the study used NHANES food intake data, which rely on participant self-report and so may not be accurate.

The study received funding from the MOE (Ministry of Education in China) Project of Humanities and Social Sciences and the Research Startup Fund of Southwest University. Dr. McIntyre has received research grant support from CIHR/GACD/Chinese National Natural Research Foundation and speaker/consultation fees from Lundbeck, Janssen, Purdue, Pfizer, Otsuka, Takeda, Neurocrine, Sunovion, Bausch Health, Novo Nordisk, Kris, Sanofi, Eisai, Intra-Cellular, NewBridge Pharmaceuticals, and AbbVie.

The fact that omega-6, considered neuroinflammatory, was associated with improved DSST score illustrates the complexity of this field, said Dr. McIntyre.

“We’re learning that when it comes to inflammation, many of the molecules in our brain that are implicated as anti-inflammatory can also be pro-inflammatory, so bad guys can be good guys and good guys can be bad guys.”

It speaks to the notion of homeostasis, he added. “Just like a seesaw; when you push this part down, that part goes up.”

The analysis showed the animal fluency score increased about 0.05 SD (around 0.3 score) with each SD (1.1 g/d) increase in dietary intake of omega-3.

There were no significant associations between other dietary fat intake and cognitive performance.

The researchers investigated the role of oxidative stress and antioxidant biomarkers (gamma glutamyl transpeptidase [GGT], bilirubin, uric acid, and vitamin D).

Cells produce oxidative radicals that are normally “mopped up” by our “innate antioxidant capability,” said Dr. McIntyre. “But in states of cognitive impairment, these oxidative stress markers accumulate and they exceed what the normal innate response is able to manage.”

The study showed GGT levels decreased with increased PUFA and omega-6 fatty acid intakes; levels of bilirubin decreased with increase in most dietary fat intakes; uric acid levels decreased with MUFA intake and omega-6/omega-3 ratio; and vitamin D levels increased with omega-3 fatty acid intake but decreased with SFAT intake.

Causal mediation analysis showed the association between dietary intake of fatty acids and DSST performance was partially mediated by GGT levels. However, Dr. McIntyre emphasized that this does not prove causality.

“The million dollar question is, is this the sole explanation for the association? In other words, is it the oxidative stress that caused the cognitive impairment and therefore correcting it improved it, or is it the case that oxidative stress is a proxy of other activities that are also taking place?”
 

 

 

A ‘plausible’ link

In an editorial, Candida Rebello, PhD, of the department of integrated physiology and molecular medicine at Pennington Biomedical Research Center, Baton Rouge, La., said the finding that omega-3 and omega-6 fatty acids are positively associated with cognition in older adults makes some sense.

She noted that aging is associated with an overt inflammatory phenotype, and evidence shows these fatty acids are precursors for bioactive molecules that play a role in self-limiting the acute inflammatory response.

Dr. Rebello said the positive association of omega-6 fatty acid with cognition shown in this study contrasts with the “common belief” that increasing dietary intake of these fatty acids enhances inflammation, but agreed the association is “plausible.”

She said it’s “essential” to determine “the underlying mechanisms that regulate the diverse features of inflammation and sort out the processes that protect from neuronal damage and those that contribute towards it.”

She noted the ratio of omega-6 to omega-3 is about 15:1 in the present day Western diet, as opposed to a 1:1 ratio in diets of the past. Omega-3 fatty acids are found in fish oil supplements and fatty fish like mackerel and salmon, while cereal, grains, and vegetable oil are sources of omega-6.

Attaining a measure of balance of fatty acids in the diet may be a “prudent approach,” said Dr. Rebello. “Substituting some meat entrées with fatty fish and polyunsaturated vegetable oils with monounsaturated fats such as olive oil are small changes that are likely to garner adherence.”

Dr. Rebello noted that the study used NHANES food intake data, which rely on participant self-report and so may not be accurate.

The study received funding from the MOE (Ministry of Education in China) Project of Humanities and Social Sciences and the Research Startup Fund of Southwest University. Dr. McIntyre has received research grant support from CIHR/GACD/Chinese National Natural Research Foundation and speaker/consultation fees from Lundbeck, Janssen, Purdue, Pfizer, Otsuka, Takeda, Neurocrine, Sunovion, Bausch Health, Novo Nordisk, Kris, Sanofi, Eisai, Intra-Cellular, NewBridge Pharmaceuticals, and AbbVie. He is a CEO of Braxia Scientific Corp.

Is there a cure for aging?

Heart disease. Cancer. Diabetes. Dementia.

Researchers spend billions of dollars every year trying to eradicate these medical scourges.

Yet even if we discover cures to these and all other chronic conditions, it won’t change our ultimate prognosis: death.

“That’s because you haven’t stopped aging,” says Jay Olshansky, PhD, a professor of epidemiology and biostatistics at the University of Illinois at Chicago School of Public Health.

But what if we could? What if we are trying to extend longevity in the wrong way? Instead of focusing on diseases, should we take aim at aging itself?

Some scientists think so. Fueled in part by a billion dollars of investor money, they are attempting to reverse-engineer your molecular biological clock. Their goal? To eliminate not merely diseases that kill people, but to prevent death itself. 
 

Hacking the code for immortality

Aubrey de Grey, PhD, a biomedical gerontologist, has drawn wide attention for his belief that the first person who will live to be 1,000 years old is already among us. 

He believes there’s no cap on how long we can live, depending on what medicines we develop in the future.

“The whole idea is that there would not be a limit on how long we can keep people healthy,” Dr. de Grey says. He’s the chief science officer and co-founder of the SENS Research Foundation, which funds research on how to put the brakes on aging.

Dr. De Grey’s view, in theory, isn’t so far-fetched.

Scientists have studied the immortal jellyfish, Turritopsis dohrnii. It’s the only animal that can cheat death by reverting from adulthood back to its polyp stage when threatened with danger or starvation.

Other clues to possible eternal life also may exist underwater. Certain marine clams can live more than 500 years. And lobsters stock a seemingly limitless supply of a youthful enzyme that has some scientists wondering if the crustacean, under the best conditions, just might live forever.

Among humans, researchers have been studying “super-agers” – people who not only live exceptionally long, but also do so without many of the chronic diseases that plague their peers. That’s even though they share some of the same bad habits as everyone else.

“They are making it past the age of 80 with their minds completely intact. That’s what’s so unusual,” Dr. Olshansky says. The rest of their bodies are doing better than those of average 80-year-olds, too.

People who reached ages 95 to 112 got cancer, heart disease, diabetes, osteoporosis, and stroke up to 24 years later than those with average lifespans, data show. Figuring out why might pave the way for targeted gene therapy to mimic the DNA of these nonagenarians and centenarians.

“There’s likely to be secrets contained within their genome that are eventually discovered that will help us develop therapeutic interventions to mimic the effects of decelerated aging,” Dr. Olshansky says.

Treating aging this way may offer a bigger payoff than targeting individual diseases. That’s because even if you manage to dodge any illnesses, there’s ultimately no escaping old age.

“Longevity is a side effect of health,” Dr. de Grey says. “If we can keep people healthy, then their likelihood of dying is reduced.”
 

 

 

Aging as a preventable condition

In 2015, Michael Cantor was prescribed metformin for prediabetes. Once that was under control, his doctor said Mr. Cantor could quit the drug. But Mr. Cantor had heard about studies testing it as an anti-aging drug. The 62-year-old Connecticut-based attorney asked if he could stay on it. A year ago Cantor’s wife, Shari, who is mayor of West Hartford, Conn., started to take metformin, too.

“I read the articles, they made a lot of sense to me, and with the number of people that have been taking this drug worldwide for decades, I felt like there was nothing to lose,” he says.

The couple can’t say if their daily doses have led to any changes in how they look or feel. After all, they’re taking the pills not to treat current ailments but to prevent ones in the future.

They may have answers soon. Nir Barzilai, MD, director of the National Institutes of Health’s Nathan Shock Centers of Excellence in the Basic Biology of Aging, is leading a study that hopes to prove aging is a preventable health condition. The TAME (Targeting Aging with Metformin) study is designed to do this by demonstrating that metformin, a cheap and widely prescribed pill for diabetes, may also be an anti-aging elixir.

The TAME trial is currently in phase III – typically the final step of research into any treatment before drugmakers can apply for FDA approval.

Earlier studies found that people with type 2 diabetes who take metformin have lower death rates from any cause, compared to peers who don’t take the drug. Metformin also seems to help curb the incidence of age-related diseases, including heart disease, dementia, and Alzheimer›s. It also may lower the risk of many types of cancer as well as raise the chances of survival. Observations made since the beginning of the COVID-19 pandemic suggest that people who get the virus while taking metformin are less likely to land in the hospital or die from it.

It’s not clear exactly how metformin works to do all that. The compound was originally derived from Galega officinalis, also known as goat’s rue, a perennial plant used as medicine since medieval times.

Dr. Barzilai says he hopes to prove that aging is a preventable condition.

“If the results are what they think they will be, the whole world could go on metformin and extend life for everybody – extend your good quality of life,” Dr. Barzilai says. “That’s what we all want. Every extra year that we could get where we’re still vigorous and vital would be amazing.”

 

 

Long life versus healthy life

Some researchers argue that only the “healthspan” – the period of life free of illness – is worth extending. Of course, a healthy lifestyle can add years to most people’s lives and actually improve cellular aging. Some of the biggest payoffs come from quitting or never smoking, logging more than 5½ hours of physical activity per week, and keeping a normal weight.

Drugs may be able to do that as well by interrupting common markers of aging, including telomere length, inflammation, oxidative stress, and slower cell metabolism.

“You don’t have to target all of these hallmarks to get improvement” in healthspans, says Dr. Barzilai, who also is director of the Institute for Aging Research at the Albert Einstein College of Medicine in the Bronx and scientific director of the American Federation for Aging Research.

“If you target one, you show benefit in the others.”

The medical term for growing old is senescence. Buffeted by DNA damage and stresses, your cells deteriorate and eventually stop multiplying, but don’t die.

That slowdown may have big consequences for your health. Your genes become more likely to get mutations, which can pave the way for cancer. Mitochondria, which produce energy in the cell, struggle to fuel your body. That can damage cells and cause chronic inflammation, which plays a part in diabetes, arthritis, ulcerative colitis, and many other diseases.

One major hallmark of aging is the growing stockpile of these senescent cells. Damaged cells become deactivated as a way to protect your body from harmful or uncontrolled cell division. But like the rotten apple that spoils the whole bunch, senescent cells encourage their neighbors to turn dysfunctional, too. They also emit proteins that trigger inflammation. Your body naturally removes these dormant cells. But older immune systems have a harder time cleaning up, so the senescent cells are more likely to hang around.

Flushing out this accumulated debris may be one way to avert aging, some experts say.

Dr. De Grey also believes that could be done with drugs.

“These therapies would actually repair [cellular] damage,” he says. “They’ll eliminate damage from the body by resetting or turning back the clock.”

James Kirkland, MD, PhD, of the Mayo Clinic, is one researcher exploring this theory. He gave a mixture of the cancer drug dasatinib and a plant pigment called quercetin to people with diabetic kidney disease. Quercetin is an antioxidant that gives grapes, tomatoes, and other fruits and vegetables their flavor.

A small phase I clinical trial showed that the dasatinib-quercetin combination got rid of senescent cells in the tissues of people with the disease.

The researchers don’t know yet if the results will translate into prolonged youth. They also don’t know how high a dosage is needed and what long-term problems the treatment might cause. People with chronic leukemia take dasatinib for years with few serious ill effects.

In another recent study, scientists used oxygen therapy to tackle senescent cells. Thirty-five adults ages 64 and older received oxygen therapy in a pressurized chamber. After 60 daily sessions, they showed a decrease in senescent cells and improvement in the length of DNA segments called telomeres. Shortened segments of telomeres are thought to be another marker of aging.

Researchers are also looking to the gene-editing technology CRISPR for anti-aging treatments, but the testing is only in mice so far.

Dr. Barzilai hopes that if the metformin trial succeeds, it will open the floodgates to a wave of new drugs that can stop or reverse human aging. Some of the major players in this field include Juvenescence, AgeX Therapeutics, LyGenesis, and Life Biosciences, which Dr. Barzilai founded.

“Until aging is seen as preventable, health plans won’t have to pay for this type of treatment,” he says. And if health plans won’t cover aging, pharmaceutical companies have little incentive to invest in drug development.

That may be the only thing standing between humans and unprecedented lifespans. The Census Bureau projects that Americans born in 2060 should live an average of 85.6 years, up from 78.7 years in 2018. Dr. De Grey’s prediction tops that mark by a factor of about 50. He believes that the life expectancy for someone born in 2100 may well be 5,000 years.

Dr. Barzilai, for his part, has a prediction that’s seemingly more modest.

“We die at 80. Getting an additional 35 years is relatively low-hanging fruit,” he says. “But I don’t believe that is a fixed limit.”

That may be the only thing standing between humans and unprecedented lifespans. The Census Bureau projects that Americans born in 2060 should live an average of 85.6 years, up from 78.7 years in 2018. Dr. De Grey’s prediction tops that mark by a factor of about 50. He believes that the life expectancy for someone born in 2100 may well be 5,000 years.

Dr. Barzilai, for his part, has a prediction that’s seemingly more modest.

“We die at 80. Getting an additional 35 years is relatively low-hanging fruit,” he says. “But I don’t believe that is a fixed limit.”

Anxiety in men tied to risk factors for CVD, diabetes

Article Type

Tue, 05/03/2022 - 15:02

Among healthy middle-aged men, those who were more anxious were more likely to develop high levels of multiple biomarkers of cardiometabolic risk over a 40-year follow-up in a new study.

“By middle adulthood, higher anxiety levels are associated with stable differences” in biomarkers of risk for coronary artery disease (CAD), stroke, and type 2 diabetes, which “are maintained into older ages,” the researchers wrote.

Anxious individuals “may experience deteriorations in cardiometabolic health earlier in life and remain on a stable trajectory of heightened risk into older ages,” they concluded.

The study, led by Lewina Lee, PhD, was published online Jan. 24, 2022, in the Journal of the American Heart Association.

“Men who had higher levels of anxiety at the beginning of the study had consistently higher biological risk for cardiometabolic disease than less anxious men from midlife into old age,” Dr. Lee, assistant professor of psychiatry, Boston University, summarized in an email.

Clinicians may not screen for heart disease and diabetes, and/or only discuss lifestyle modifications when patients are older or have the first signs of disease, she added.

However, the study findings “suggest that worries and anxiety are associated with preclinical pathophysiological processes that tend to culminate in cardiometabolic disease” and show “the importance of screening for mental health difficulties, such as worries and anxiety, in men as early as in their 30s and 40s,” she stressed.

Since most of the men were White (97%) and veterans (94%), “it would be important for future studies to evaluate if these associations exist among women, people from diverse racial and ethnic groups, and in more socioeconomically varying samples, and to consider how anxiety may relate to the development of cardiometabolic risk in much younger individuals than those in our study,” Dr. Lee said in a press release from the American Heart Association.

“This study adds to the growing body of research that link psychological health to cardiovascular risk,” Glenn N. Levine, MD, who was not involved with this research, told this news organization in an email.

“We know that factors such as depression and stress can increase cardiac risk; this study further supports that anxiety can as well,” added Dr. Levine, chief of cardiology, Michael E. DeBakey Veterans Affairs Medical Center, Houston.

“Everyone experiences some anxiety in their life,” he added. However, “if a provider senses that a patient’s anxiety is far beyond the ‘normal’ that we all have from time to time, and it is seemingly adversely impacting both their psychological and physical health, it would be reasonable to suggest to the patient that it might be useful to speak with a mental health professional, and if the patient is receptive, to then make a formal consultation or referral,” said Dr. Levine, who was writing group chair of a recent AHA Scientific Statement on mind-heart-body connection.
 

Neuroticism and worry

Several studies have linked anxiety to a greater risk of cardiometabolic disease onset, Dr. Lee and colleagues wrote, but it is unclear if anxious individuals have a steadily worsening risk as they age, or if they have a higher risk in middle age, which stays the same in older age.

To investigate this, they analyzed data from 1561 men who were seen at the VA Boston outpatient clinic and did not have CAD, type 2 diabetes, stroke, or cancer when they enrolled in the Normative Aging Study.

The men had a mean age of 53 years (range, 33-84) in 1975 and were followed until 2015 or until dropout from the study or death.

At baseline, the study participants filled in the Eysenck Personality Inventory, which assesses neuroticism, and also responded to a scale indicating how much they worry about 20 issues (excluding health).

“Neuroticism,” the researchers explained, “is a tendency to perceive experiences as threatening, feel that challenges are uncontrollable, and experience frequent and disproportionately intense negative emotions,” such as fear, anxiety, sadness, and anger, “across many situations.”

“Worry refers to attempts to solve a problem where future outcome is uncertain and potentially positive or negative,” Dr. Lee noted. Although worry can be healthy and lead to constructive solutions, “it may be unhealthy, especially when it becomes uncontrollable and interferes with day-to-day functioning.”

Of note, in 1980, the American Psychiatric Association removed the term neurosis from its diagnostic manual. What was previously called neurosis is included as part of generalized anxiety disorder; GAD also encompasses excessive worry.
 

Cardiometabolic risk from midlife to old age

The men in the current study had on-site physical examinations every 3-5 years.

The researchers calculated the men’s cardiometabolic risk score (from 0 to 7) by assigning 1 point each for the following: systolic blood pressure greater than 130 mm Hg, diastolic blood pressure greater than 85 mm Hg, total cholesterol of at least 240 mg/dL, triglycerides of at least 150 mg/dL, body mass index of at least 30 kg/m2, glucose of at least 100 mg/dL, and erythrocyte sedimentation rate of at least 14 mm/hour.

Alternatively, patients were assigned a point each for taking medication that could affect these markers (except for body mass index).

Overall, on average, at baseline, the men had a cardiometabolic risk score of 2.9. From age 33-65, this score increased to 3.8, and then it did not increase as much later on.

That is, the cardiometabolic risk score increased by 0.8 per decade until age 65, followed by a slower increase of 0.5 per decade.

At all ages, men with higher levels of neuroticism or worry had a higher cardiometabolic risk score

Each additional standard deviation of neuroticism was associated with a 13% increased risk of having six or more of the seven cardiometabolic risk markers during follow-up, after adjusting for age, demographics, and family history of CAD, but the relationship was attenuated after also adjusting for health behaviors (for example, smoking, alcohol consumption, physical activity, and past-year physician visit at baseline).

Similarly, each additional standard deviation of worry was associated with a 10% increased risk of having six or more of the seven cardiometabolic risk markers during follow-up after the same adjustments, and was also no longer significantly different after the same further adjustments.

The research was supported by grants from the National Institutes of Health and a Senior Research Career Scientist Award from the Office of Research and Development, Department of Veterans Affairs. The Normative Aging Study is a research component of the Massachusetts Veterans Epidemiology Research and Information Center and is supported by the VA Cooperative Studies Program/Epidemiological Research Centers. The study authors and Dr. Levine disclosed no relevant financial relationships.

AHA annual stats update highlights heart-brain connection

Article Type
Changed
Tue, 05/03/2022 - 15:02

The American Heart Association (AHA) draws attention to the important bidirectional link between cardiovascular health and brain health in its annual statistical update on heart disease and stroke.

“For several years now, the AHA and the scientific community have increasingly recognized the connections between cardiovascular health and brain health, so it was time for us to cement this into its own chapter, which we highlight as the brain health chapter,” Connie W. Tsao, MD, MPH, chair of the statistical update writing group, with Harvard Medical School, Boston, said in an AHA podcast.

“The global rate of brain disease is quickly outpacing heart disease,” Mitchell S. V. Elkind, MD, immediate past president of the AHA, added in a news release.

“The rate of deaths from Alzheimer’s disease and other dementias rose more than twice as much in the past decade compared to the rate of deaths from heart disease, and that is something we must address,” said Dr. Elkind, with Columbia University Vagelos College of Physicians and Surgeons in New York.

“It’s becoming more evident that reducing vascular disease risk factors can make a real difference in helping people live longer, healthier lives, free of heart disease and brain disease,” Dr. Elkind added.

The AHA’s Heart Disease and Stroke Statistics – 2022 Update was published online January 26 in Circulation).

The report highlights some of the research connecting heart and brain health, including the following:

  • A meta-analysis of 139 studies showed that people with midlife hypertension were five times more likely to experience impairment on global cognition and about twice as likely to experience reduced executive function, dementia, and Alzheimer’s disease.
  • A meta-analysis of four longitudinal studies found that the risk for dementia associated with heart failure was increased nearly twofold.
  • In the large prospective Atherosclerosis Risk in Communities (ARIC) Neurocognitive Study, atrial fibrillation was associated with greater cognitive decline and dementia over 20 years.
  • A meta-analysis of 10 prospective studies (including 24,801 participants) showed that coronary heart disease (CHD) was associated with a 40% increased risk of poor cognitive outcomes, including dementia, cognitive impairment, or cognitive decline.

“This new chapter on brain health was a critical one to add,” Dr. Tsao said in the news release.

“The data we’ve collected brings to light the strong correlations between heart health and brain health and makes it an easy story to tell -- what’s good for the heart is good for the brain,” Dr. Tsao added.

Along with the new chapter on brain health, the 2022 statistical update provides the latest statistics and heart disease and stroke. Among the highlights:

  • Cardiovascular disease (CVD) remains the leading cause of death worldwide. In the United States in 2019, CVD, listed as the underlying cause of death, accounted for 874,613 deaths, about 2,396 deaths each day. On average, someone dies of CVD every 36 seconds.
  • CVD claims more lives each year in the United States than all forms of cancer and chronic lower respiratory disease combined.
  • In 2019, CHD was the leading cause (41.3%) of deaths attributable to CVD, followed by other CVD (17.3%), stroke (17.2%), hypertension (11.7%), heart failure (9.9%), and diseases of the arteries (2.8%).
  • In 2019, stroke accounted for roughly 1 in every 19 deaths in the United States. On average, someone in the United States has a stroke every 40 seconds and someone dies of stroke every 3 minutes 30 seconds. When considered separately from other CVD, stroke ranks number five among all causes of death in the United States.
 

 

While the annual statistics update aims to be a contemporary update of annual heart disease and stroke statistics over the past year, it also examines trends over time, Dr. Tsao explains in the podcast.

“One noteworthy point is that we saw a decline in the rate of cardiovascular mortality over the past three decades or so until about 2010. But over the past decade now, we’re also seeing a rise in these numbers,” she said.

This could be due to rising rates of obesity, diabetes, and poor hypertension control, as well as other lifestyle behaviors, Tsao said.
 

Key risk factor data

Each year, the statistical update gauges the cardiovascular health of Americans by tracking seven key health factors and behaviors that increase risk for heart disease and stroke. Below is a snapshot of the latest risk factor data.

Smoking

In 2019, smoking was the leading risk factor for years of life lost to premature death and the third leading risk factor for years of life lived with disability or injury.

According to the 2020 surgeon general’s report on smoking cessation, more than 480,000 Americans die as a result of cigarette smoking, and more than 41,000 die of secondhand smoke exposure each year (roughly 1 in 5 deaths annually).

One in 7 adults are current smokers, 1 in 6 female adults are current smokers, and 1 in 5 high school students use e-cigarettes.
 

Physical inactivity

In 2018, 25.4% of U.S. adults did not engage in leisure-time physical activity, and only 24.0% met the 2018 Physical Activity Guidelines for Americans for both aerobic and muscle strengthening.

Among U.S. high school students in 2019, only 44.1% were physically active for 60 minutes or more on at least 5 days of the week.
 

Nutrition

While there is some evidence that Americans are improving their diet, fewer than 10% of U.S. adults met guidelines for whole grain, whole fruit, and nonstarchy vegetable consumption each day in 2017–2018.

Overweight/obesity

The prevalence of obesity among adults increased from 1999–2000 through 2017–2018 from 30.5% to 42.4%. Overall prevalence of obesity and severe obesity in U.S. youth 2 to 19 years of age increased from 13.9% to 19.3% and 2.6% to 6.1% between 1999–2000 and 2017–2018.

Cholesterol

Close to 94 million (38.1%) U.S. adults have total cholesterol of 200 mg/dL or higher, according to 2015–2018 data; about 28.0 million (11.5%) have total cholesterol of 240 mg/dL or higher; and 27.8% have high levels of low-density lipoprotein cholesterol (130 mg/dL or higher).

Diabetes

In 2019, 87,647 U.S. deaths were attributed to diabetes; data show that 9.8 million U.S. adults have undiagnosed diabetes, 28.2 million have diagnosed diabetes, and 113.6 million have prediabetes.

Hypertension

A total of 121.5 million (47.3%) U.S. adults have hypertension, based on 2015–2018 data. In 2019, 102,072 U.S. deaths were primarily attributable to hypertension.

This statistical update was prepared by a volunteer writing group on behalf of the American Heart Association Council on Epidemiology and Prevention Statistics Committee and Stroke Statistics Subcommittee. Disclosures for the writing committee are listed with the original article.

According to the 2020 surgeon general’s report on smoking cessation, more than 480,000 Americans die as a result of cigarette smoking, and more than 41,000 die of secondhand smoke exposure each year (roughly 1 in 5 deaths annually).

One in 7 adults are current smokers, 1 in 6 female adults are current smokers, and 1 in 5 high school students use e-cigarettes.
 

Physical inactivity

In 2018, 25.4% of U.S. adults did not engage in leisure-time physical activity, and only 24.0% met the 2018 Physical Activity Guidelines for Americans for both aerobic and muscle strengthening.

Among U.S. high school students in 2019, only 44.1% were physically active for 60 minutes or more on at least 5 days of the week.
 

Nutrition

While there is some evidence that Americans are improving their diet, fewer than 10% of U.S. adults met guidelines for whole grain, whole fruit, and nonstarchy vegetable consumption each day in 2017–2018.

Overweight/obesity

The prevalence of obesity among adults increased from 1999–2000 through 2017–2018 from 30.5% to 42.4%. Overall prevalence of obesity and severe obesity in U.S. youth 2 to 19 years of age increased from 13.9% to 19.3% and 2.6% to 6.1% between 1999–2000 and 2017–2018.

Cholesterol

Close to 94 million (38.1%) U.S. adults have total cholesterol of 200 mg/dL or higher, according to 2015–2018 data; about 28.0 million (11.5%) have total cholesterol of 240 mg/dL or higher; and 27.8% have high levels of low-density lipoprotein cholesterol (130 mg/dL or higher).

Diabetes

In 2019, 87,647 U.S. deaths were attributed to diabetes; data show that 9.8 million U.S. adults have undiagnosed diabetes, 28.2 million have diagnosed diabetes, and 113.6 million have prediabetes.

Hypertension

A total of 121.5 million (47.3%) U.S. adults have hypertension, based on 2015–2018 data. In 2019, 102,072 U.S. deaths were primarily attributable to hypertension.

This statistical update was prepared by a volunteer writing group on behalf of the American Heart Association Council on Epidemiology and Prevention Statistics Committee and Stroke Statistics Subcommittee. Disclosures for the writing committee are listed with the original article.

The American Heart Association (AHA) draws attention to the important bidirectional link between cardiovascular health and brain health in its annual statistical update on heart disease and stroke.

“For several years now, the AHA and the scientific community have increasingly recognized the connections between cardiovascular health and brain health, so it was time for us to cement this into its own chapter, which we highlight as the brain health chapter,” Connie W. Tsao, MD, MPH, chair of the statistical update writing group, with Harvard Medical School, Boston, said in an AHA podcast.

“The global rate of brain disease is quickly outpacing heart disease,” Mitchell S. V. Elkind, MD, immediate past president of the AHA, added in a news release.

“The rate of deaths from Alzheimer’s disease and other dementias rose more than twice as much in the past decade compared to the rate of deaths from heart disease, and that is something we must address,” said Dr. Elkind, with Columbia University Vagelos College of Physicians and Surgeons in New York.

“It’s becoming more evident that reducing vascular disease risk factors can make a real difference in helping people live longer, healthier lives, free of heart disease and brain disease,” Dr. Elkind added.

The AHA’s Heart Disease and Stroke Statistics – 2022 Update was published online January 26 in Circulation).

The report highlights some of the research connecting heart and brain health, including the following:

  • A meta-analysis of 139 studies showed that people with midlife hypertension were five times more likely to experience impairment on global cognition and about twice as likely to experience reduced executive function, dementia, and Alzheimer’s disease.
  • A meta-analysis of four longitudinal studies found that the risk for dementia associated with heart failure was increased nearly twofold.
  • In the large prospective Atherosclerosis Risk in Communities (ARIC) Neurocognitive Study, atrial fibrillation was associated with greater cognitive decline and dementia over 20 years.
  • A meta-analysis of 10 prospective studies (including 24,801 participants) showed that coronary heart disease (CHD) was associated with a 40% increased risk of poor cognitive outcomes, including dementia, cognitive impairment, or cognitive decline.

“This new chapter on brain health was a critical one to add,” Dr. Tsao said in the news release.

“The data we’ve collected brings to light the strong correlations between heart health and brain health and makes it an easy story to tell -- what’s good for the heart is good for the brain,” Dr. Tsao added.

Along with the new chapter on brain health, the 2022 statistical update provides the latest statistics and heart disease and stroke. Among the highlights:

  • Cardiovascular disease (CVD) remains the leading cause of death worldwide. In the United States in 2019, CVD, listed as the underlying cause of death, accounted for 874,613 deaths, about 2,396 deaths each day. On average, someone dies of CVD every 36 seconds.
  • CVD claims more lives each year in the United States than all forms of cancer and chronic lower respiratory disease combined.
  • In 2019, CHD was the leading cause (41.3%) of deaths attributable to CVD, followed by other CVD (17.3%), stroke (17.2%), hypertension (11.7%), heart failure (9.9%), and diseases of the arteries (2.8%).
  • In 2019, stroke accounted for roughly 1 in every 19 deaths in the United States. On average, someone in the United States has a stroke every 40 seconds and someone dies of stroke every 3 minutes 30 seconds. When considered separately from other CVD, stroke ranks number five among all causes of death in the United States.
 

 

While the annual statistics update aims to be a contemporary update of annual heart disease and stroke statistics over the past year, it also examines trends over time, Dr. Tsao explains in the podcast.

“One noteworthy point is that we saw a decline in the rate of cardiovascular mortality over the past three decades or so until about 2010. But over the past decade now, we’re also seeing a rise in these numbers,” she said.

This could be due to rising rates of obesity, diabetes, and poor hypertension control, as well as other lifestyle behaviors, Tsao said.
 

Key risk factor data

Each year, the statistical update gauges the cardiovascular health of Americans by tracking seven key health factors and behaviors that increase risk for heart disease and stroke. Below is a snapshot of the latest risk factor data.

Smoking

In 2019, smoking was the leading risk factor for years of life lost to premature death and the third leading risk factor for years of life lived with disability or injury.

According to the 2020 surgeon general’s report on smoking cessation, more than 480,000 Americans die as a result of cigarette smoking, and more than 41,000 die of secondhand smoke exposure each year (roughly 1 in 5 deaths annually).

Chronic stress accelerates aging: Epigenetic evidence

Article Type
Changed
Wed, 02/09/2022 - 10:28

The increase in cardiovascular disease caused by chronic stress is related to biologic mechanisms (metabolic, hormonal, inflammatory) and to behavioral mechanisms (lifestyle). There is a popular saying that “stress speeds up aging,” which makes sense if we consider the age-old idea that “our age corresponds to that of our arteries.”

The study of the mechanisms of psychosocial risk factors is of major relevance to the creation of the individual and communal preventive strategies that ensure longevity and maintain quality of life.

The following hypotheses were proposed by a group of researchers from Yale University, in New Haven, Conn., in a recent study:

1. Stress is positively associated with accelerated biologic aging, and this relationship will be mediated by stress-related physiologic changes, such as insulin and hypothalamic-pituitary-adrenal (HPA) signaling.

2. Strong factors associated with psychologic resilience will be protective against the negative consequences of stress on aging. (These relationships are predictive, not causative, as this study is cross-sectional.)
 

The study

In their study, the team assessed 444 adults with no chronic medical conditions or psychiatric disorders who were 18-50 years of age and living in the greater New Haven area. Levels of obesity and alcohol consumption in the study cohort were generally in line with those in a community population, so alcohol use and body mass index were used as covariates to account for their impact on the results.

The team also used the latest “epigenetic clock,” known as GrimAge. In recent years, several methods of determining biologic age have been developed that trace chemical changes in the DNA that are natural to the aging process but occur at different moments in different people. The epigenetic clocks have proved to be better predictors of longevity and health than chronologic age, and GrimAge predicts mortality better than other epigenetic clocks.
 

Results

1. Cumulative stress was associated with the acceleration of GrimAge and stress-related physiologic measures of adrenal sensitivity (cortisol/ACTH ratio) and insulin resistance (HOMA). After the researchers controlled for demographic and behavioral factors, HOMA was correlated with GrimAge acceleration.

2. Psychologic resilience factors moderated the association between stress and aging, such that with worse regulation of emotions, there was greater stress-related age acceleration, and with stronger regulation of emotions, any significant effect of stress on GrimAge was prevented. Self-control moderated the relationship between stress and insulin resistance, with high self-control blunting this relationship.

3. In the final model, in those with poor emotion regulation, cumulative stress continued to predict additional GrimAge acceleration, even when demographic, physiologic, and behavioral covariates were accounted for.
 

Implications

These results elegantly demonstrate that cumulative stress is associated with epigenetic aging in a healthy population, and these associations are modified by biobehavioral resilience factors.

Even after adjustment for demographic and behavioral factors – such as smoking, body mass index, race, and income – people with high chronic stress scores showed markers of accelerated aging and physiologic changes, such as increased insulin resistance.

However, individuals with high scores on two psychologic resilience measures – emotion regulation and self-control – were more resilient to the effects of stress on aging and insulin resistance.

These results support the popular notion that stress ages (and sickens) us, and suggest a viable way of minimizing the adverse consequences of stress by strengthening the regulation of emotion and self-control.

In other words, the greater the psychologic resilience, the more likely the individual is to live a long and healthy life. “We like to feel as if we have some sovereignty over our destiny and, therefore, it is worth emphasizing to people (and healthcare providers) that it is important to invest in mental health,” said one of the study researchers.

With all the stress we face these days, it is essential to remember that there is no health without mental health. Above all, if we can achieve greater psychologic resilience, we will have a better chance of delaying aging.

Boosted Americans 97 times less likely to die of COVID-19 than unvaccinated

Article Type
Changed
Fri, 02/04/2022 - 15:20

Americans who have received a COVID-19 booster shot are 97 times less likely to die from the coronavirus than those who aren’t vaccinated, according to a new update from the CDC.

In addition, fully vaccinated Americans — meaning those with up to two doses, but no booster — are 14 times less likely to die from COVID-19 than unvaccinated people.

“These data confirm that vaccination and boosting continues to protect against severe illness and hospitalization, even during the Omicron surge,” Rochelle Walensky, MD, director of the CDC, said during a briefing by the White House COVID-19 Response Team.

“If you are not up to date on your COVID-19 vaccinations, you have not optimized your protection against severe disease and death, and you should get vaccinated and boosted if you are eligible,” she said.

Dr. Walensky presented the latest numbers on Feb. 2 based on reports from 25 jurisdictions in early December. The number of average weekly deaths for those who were unvaccinated was 9.7 per 100,000 people, as compared with 0.7 of those who were vaccinated and 0.1 of those who had received a booster.

“The data are really stunningly obvious why a booster is really very important,” Anthony Fauci, MD, director of the National Institute of Allergy and Infectious Diseases, said during the briefing.

Dr. Fauci also encouraged vaccination for those who are pregnant and couples who may want to conceive in the near feature. He highlighted two recent studies that found vaccination in either partner didn’t affect fertility, including in vitro fertilization.

Meanwhile, fertility fell temporarily among men who were infected with the coronavirus. Couples were 18% less likely to conceive if the male partner had contracted the coronavirus within 60 days before a menstrual cycle.

“New data adds to previous studies that indicate that COVID-19 vaccination does not negatively impact fertility,” Dr. Fauci said. “Vaccination is recommended for people who are trying to get pregnant now or might become pregnant in the future, as well as their partners.”

About 80% of eligible Americans have received at least one vaccine dose, and 68% are fully vaccinated, according to the latest CDC data. About 51% of those who are eligible for a booster dose have received one.

The FDA could authorize the Pfizer vaccine for children under age 5 later this month. When that happens, about 18 million children will qualify for a shot, Jeff Zients, coordinator of the White House COVID-19 Response Team, said during the briefing. The Biden administration is already working on distribution plans for the shot for young kids, he added.

“We’ll be ready to start getting shots in arms soon after FDA and CDC make their decisions,” he said.

Lifestyle likely responsible for obesity in children, not mother’s BMI

Article Type
Changed
Mon, 02/07/2022 - 09:43

Lifestyle is more likely to affect a child’s body mass index than the weight of their mother before and during pregnancy say researchers who have found that a mother’s high BMI before and during pregnancy is not a major cause of high BMI in their offspring – indicating that childhood and teen obesity is more likely to be a result of lifestyle factors.

According to UK Government figures 9.9% of reception age children (age 4-5) are obese, with a further 13.1% overweight. At age 10-11 (year 6), 21.0% are obese and 14.1% overweight.

Research from the Centre for Longitudinal Studies (CLS) at the UCL Social Research Institute, published in December 2020, showed that one in five (21%) young people were obese at age 17, and a further one in seven (14%) were overweight.
 

Nature or nurture

Greater maternal BMI before or during pregnancy is known to be associated with higher BMI throughout childhood, but exactly how much a mother’s weight before or during pregnancy contributes to childhood obesity, or whether it is lifestyle and environmental factors that are responsible, remains unclear.

To investigate this question researchers from the University of Bristol (England) and Imperial College London used data from the “Children of the 90s” (also known as the Avon Longitudinal Study of Parents and Children), and data from the “Born in Bradford” longitudinal study.

For their study, published in BMC Medicine, researchers used Mendelian randomisation, measuring variation in genes to determine the effect of an exposure on an outcome, along with polygenic risk scores, to investigate if associations between before and during early pregnancy BMI, and a child’s BMI from birth to adolescence, are causal.

They looked at birth weight and BMI at age 1 and 4 years in both “Children of the 90s” and “Born in Bradford” participants, and then also BMI at age 10 and 15 years in just the Children of the 90s participants.

Since the effects being explored may differ by ethnicity the authors reported that they limited analyses to two ethnic groups – White European and South Asian.
 

Interventions targeting everyone needed

The researchers found that there was a moderate causal effect between maternal BMI and the birth weight of children, however they said they “found no strong evidence for a causal effect of maternal BMI on offspring adiposity beyond birth”.

Tom Bond, MSc, senior research associate at the University of Bristol, explained: “We found that if women are heavier at the start of pregnancy this isn’t a strong cause of their children being heavier as teenagers.”

The authors wrote that their results suggested that “higher maternal pre-/early-pregnancy BMI is not a key driver of higher adiposity in the next generation,” something that Mr. Bond said was “important to know”.

The authors concluded that their findings “support interventions that target the whole population for reducing overweight and obesity, rather than a specific focus on women of reproductive age”.

Mr. Bond pointed out that “it isn’t enough to just focus on women entering pregnancy.” However, “there is good evidence that maternal obesity causes other health problems for mothers and babies, so prospective mothers should still be encouraged and supported to maintain a healthy weight.”

Lifestyle is more likely to affect a child’s body mass index than the weight of their mother before and during pregnancy say researchers who have found that a mother’s high BMI before and during pregnancy is not a major cause of high BMI in their offspring – indicating that childhood and teen obesity is more likely to be a result of lifestyle factors.

According to UK Government figures 9.9% of reception age children (age 4-5) are obese, with a further 13.1% overweight. At age 10-11 (year 6), 21.0% are obese and 14.1% overweight.

Research from the Centre for Longitudinal Studies (CLS) at the UCL Social Research Institute, published in December 2020, showed that one in five (21%) young people were obese at age 17, and a further one in seven (14%) were overweight.
 

Nature or nurture

Greater maternal BMI before or during pregnancy is known to be associated with higher BMI throughout childhood, but exactly how much a mother’s weight before or during pregnancy contributes to childhood obesity, or whether it is lifestyle and environmental factors that are responsible, remains unclear.

To investigate this question researchers from the University of Bristol (England) and Imperial College London used data from the “Children of the 90s” (also known as the Avon Longitudinal Study of Parents and Children), and data from the “Born in Bradford” longitudinal study.

For their study, published in BMC Medicine, researchers used Mendelian randomisation, measuring variation in genes to determine the effect of an exposure on an outcome, along with polygenic risk scores, to investigate if associations between before and during early pregnancy BMI, and a child’s BMI from birth to adolescence, are causal.

They looked at birth weight and BMI at age 1 and 4 years in both “Children of the 90s” and “Born in Bradford” participants, and then also BMI at age 10 and 15 years in just the Children of the 90s participants.

Since the effects being explored may differ by ethnicity the authors reported that they limited analyses to two ethnic groups – White European and South Asian.
 

Interventions targeting everyone needed

The researchers found that there was a moderate causal effect between maternal BMI and the birth weight of children, however they said they “found no strong evidence for a causal effect of maternal BMI on offspring adiposity beyond birth”.

Tom Bond, MSc, senior research associate at the University of Bristol, explained: “We found that if women are heavier at the start of pregnancy this isn’t a strong cause of their children being heavier as teenagers.”

The authors wrote that their results suggested that “higher maternal pre-/early-pregnancy BMI is not a key driver of higher adiposity in the next generation,” something that Mr. Bond said was “important to know”.

The authors concluded that their findings “support interventions that target the whole population for reducing overweight and obesity, rather than a specific focus on women of reproductive age”.
