When you can’t fit your entire workout into a busy day, do you think there’s no point in doing anything at all? You should rethink that mindset. Just 11 minutes of moderate-to-vigorous intensity aerobic activity per day could lower your risk of cancer, cardiovascular disease or premature death, a large new study has found.

Aerobic activities include walking, dancing, running, jogging, cycling and swimming. You can gauge the intensity level of an activity by your heart rate and how hard you’re breathing as you move. Generally, being able to talk but not sing during an activity would make it moderate intensity. Vigorous intensity is marked by the inability to carry on a conversation.

Higher levels of physical activity have been associated with lower rates of premature death and chronic disease, according to past research. But how the risk levels for these outcomes are affected by the amount of exercise someone gets has been more difficult to determine. To explore this impact, scientists largely from the University of Cambridge in the United Kingdom looked at data from 196 studies, amounting to more than 30 million adult participants who were followed for 10 years on average. The results of this latest study were published Tuesday in the British Journal of Sports Medicine.

The study mainly focused on participants who had done the minimum recommended amount of 150 minutes of exercise per week, or 22 minutes per day. Compared with inactive participants, adults who had done 150 minutes of moderate-to-vigorous aerobic physical activity per week had a 31% lower risk of dying from any cause, a 29% lower risk of dying from cardiovascular disease and a 15% lower risk of dying from cancer.

The same amount of exercise was linked with a 27% lower risk of developing cardiovascular disease and 12% lower risk when it came to cancer.

“This is a compelling systematic review of existing research,” said CNN Medical Analyst Dr. Leana Wen, an emergency physician and public health professor at George Washington University, who wasn’t involved in the research. “We already knew that there was a strong correlation between increased physical activity and reduced risk for cardiovascular disease, cancer and premature death. This research confirms it, and furthermore states that a smaller amount than the 150 minutes of recommended exercise a week can help.”

Even people who got just half the minimum recommended amount of physical activity benefited. Accumulating 75 minutes of moderate-intensity activity per week — about 11 minutes of activity per day — was associated with a 23% lower risk of early death. Getting active for 75 minutes on a weekly basis was also enough to reduce the risk of developing cardiovascular disease by 17% and cancer by 7%.

Beyond 150 minutes per week, any additional benefits were smaller.

“If you are someone who finds the idea of 150 minutes of moderate-intensity physical activity a week a bit daunting, then our findings should be good news,” said study author Dr. Soren Brage, group leader of the Physical Activity Epidemiology group in the Medical Research Council Epidemiology Unit at the University of Cambridge, in a news release. “This is also a good starting position — if you find that 75 minutes a week is manageable, then you could try stepping it up gradually to the full recommended amount.”

The authors’ findings affirm the World Health Organization’s position that doing some physical activity is better than doing none, even if you don’t get the recommended amounts of exercise.

“One in 10 premature deaths could have been prevented if everyone achieved even half the recommended level of physical activity,” the authors wrote in the study. Additionally, “10.9% and 5.2% of all incident cases of CVD (cardiovascular disease) and cancer would have been prevented.”

Important note: If you experience pain while exercising, stop immediately. Check with your doctor before beginning any new exercise program.

The authors didn’t have details on the specific types of physical activity the participants did. But some experts do have thoughts on how physical activity could reduce risk for chronic diseases and premature death.

“There are many potential mechanisms including the improvement and maintenance of body composition, insulin resistance and physical function because of a wide variety of favorable influences of aerobic activity,” said Haruki Momma, an associate professor of medicine and science in sports and exercise at Tohoku University in Japan. Momma wasn’t involved in the research.

Benefits could also include improvement to immune function, lung and heart health, inflammation levels, hypertension, cholesterol, and amount of body fat, said Eleanor Watts, a postdoctoral fellow in the division of cancer epidemiology and genetics at the National Cancer Institute. Watts wasn’t involved in the research.

“These translate into lower risk of getting chronic diseases,” said Peter Katzmarzyk, associate executive director for population and public health sciences at Pennington Biomedical Research Center in Baton Rouge, Louisiana. Katzmarzyk wasn’t involved in the research.

The fact that participants who did only half the minimum recommended amount of exercise still experienced benefits doesn’t mean people shouldn’t aim for more exercise, but rather that “perfect shouldn’t be the enemy of the good,” Wen said. “Some is better than none.”

To get up to 150 minutes of physical activity per week, find activities you enjoy, Wen said. “You are far more likely to engage in something you love doing than something you have to make yourself do.”

And when it comes to how you fit in your exercise, you can think outside the box.

“Moderate activity doesn’t have to involve what we normally think of (as) exercise, such as sports or running,” said study coauthor Leandro Garcia, a lecturer in the school of medicine, dentistry and biomedical sciences at Queen’s University Belfast, in a news release. “Sometimes, replacing some habits is all that is needed.

“For example, try to walk or cycle to your work or study place instead of using a car, or engage in active play with your kids or grand kids. Doing activities that you enjoy and that are easy to include in your weekly routine is an excellent way to become more active.”

Zero-calorie sweetener linked to heart attack and stroke, study finds | CNN

 — 

A sugar replacement called erythritol – used to add bulk or sweeten stevia, monkfruit and keto reduced-sugar products – has been linked to blood clotting, stroke, heart attack and death, according to a new study.

“The degree of risk was not modest,” said lead study author Dr. Stanley Hazen, director of the Center for Cardiovascular Diagnostics and Prevention at the Cleveland Clinic Lerner Research Institute.

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, according to the study, published Monday in the journal Nature Medicine.

“If your blood level of erythritol was in the top 25% compared to the bottom 25%, there was about a two-fold higher risk for heart attack and stroke. It’s on par with the strongest of cardiac risk factors, like diabetes,” Hazen said.

Additional lab and animal research presented in the paper revealed that erythritol appeared to be causing blood platelets to clot more readily. Clots can break off and travel to the heart, triggering a heart attack, or to the brain, triggering a stroke.

“This certainly sounds an alarm,” said Dr. Andrew Freeman, director of cardiovascular prevention and wellness at National Jewish Health, a hospital in Denver, who was not involved in the research.

“There appears to be a clotting risk from using erythritol,” Freeman said. “Obviously, more research is needed, but in an abundance of caution, it might make sense to limit erythritol in your diet for now.”

In response to the study, the Calorie Control Council, an industry association, told CNN that “the results of this study are contrary to decades of scientific research showing reduced-calorie sweeteners like erythritol are safe, as evidenced by global regulatory permissions for their use in foods and beverages,” said Robert Rankin, the council’s executive director, in an email.

The results “should not be extrapolated to the general population, as the participants in the intervention were already at increased risk for cardiovascular events,” Rankin said.

The European Association of Polyol Producers declined to comment, saying it had not reviewed the study.

Like sorbitol and xylitol, erythritol is a sugar alcohol, a carb found naturally in many fruits and vegetables. It has about 70% of the sweetness of sugar and is considered zero-calorie, according to experts.

Artificially manufactured in massive quantities, erythritol has no lingering aftertaste, doesn’t spike blood sugar and has less of a laxative effect than some other sugar alcohols.

“Erythritol looks like sugar, it tastes like sugar, and you can bake with it,” said Hazen, who also directs the Cleveland Clinic’s Center for Microbiome and Human Health.

“It’s become the sweetheart of the food industry, an extremely popular additive to keto and other low-carb products and foods marketed to people with diabetes,” he added. “Some of the diabetes-labeled foods we looked at had more erythritol than any other item by weight.”

Erythritol is also the largest ingredient by weight in many “natural” stevia and monkfruit products, Hazen said. Because stevia and monkfruit are about 200 to 400 times sweeter than sugar, just a small amount is needed in any product. The bulk of the product is erythritol, which adds the sugar-like crystalline appearance and texture consumers expect.

The discovery of the connection between erythritol and cardiovascular issues was purely accidental, Hazen said: “We never expected this. We weren’t even looking for it.”

Hazen’s research had a simple goal: find unknown chemicals or compounds in a person’s blood that might predict their risk for a heart attack, stroke or death in the next three years. To do so, the team began analyzing 1,157 blood samples in people at risk for heart disease collected between 2004 and 2011.

“We found this substance that seemed to play a big role, but we didn’t know what it was,” Hazen said. “Then we discovered it was erythritol, a sweetener.”

The human body naturally creates erythritol but in very low amounts that would not account for the levels they measured, he said.

To confirm the findings, Hazen’s team tested another batch of blood samples from over 2,100 people in the United States and an additional 833 samples gathered by colleagues in Europe through 2018. About three-quarters of the participants in all three populations had coronary disease or high blood pressure, and about a fifth had diabetes, Hazen said. Over half were male and in their 60s and 70s.

In all three populations, researchers found that higher levels of erythritol were connected to a greater risk of heart attack, stroke or death within three years.

But why? To find out, researchers did further animal and lab tests and discovered that erythritol was “provoking enhanced thrombosis,” or clotting in the blood, Hazen said.

Clotting is necessary in the human body, or we would bleed to death from cuts and injuries. The same process is constantly happening internally, as well.

“Our blood vessels are always under pressure, and we spring leaks, and blood platelets are constantly plugging these holes all the time,” Hazen said.

However, the size of the clot made by platelets depends on the size of the trigger that stimulates the cells, he explained. For example, if the trigger is only 10%, then you only get 10% of a clot.

“But what we’re seeing with erythritol is the platelets become super responsive: A mere 10% stimulant produces 90% to 100% of a clot formation,” Hazen said.

“For people who are at risk for clotting, heart attack and stroke – like people with existing cardiac disease or people with diabetes – I think that there’s sufficient data here to say stay away from erythritol until more studies are done,” Hazen said.

Oliver Jones, a professor of chemistry at RMIT University in Victoria, Australia, noted that the study had revealed only a correlation, not causation.

“As the authors themselves note, they found an association between erythritol and clotting risk, not definitive proof such a link exists,” Jones, who was not involved in the research, said in a statement.

“Any possible (and, as yet unproven) risks of excess erythritol would also need to be balanced against the very real health risks of excess glucose consumption,” Jones said.

In a final part of the study, eight healthy volunteers drank a beverage that contained 30 grams of erythritol, the amount many people in the US consume, Hazen said, according to the National Health and Nutrition Examination Survey, which examines American nutrition each year.

Blood tests over the next three days tracked erythritol levels and clotting risk.

“Thirty grams was enough to make blood levels of erythritol go up a thousandfold,” Hazen said. “It remained elevated above the threshold necessary to trigger and heighten clotting risk for the following two to three days.”

Just how much is 30 grams of erythritol? The equivalent of eating a pint of keto ice cream, Hazen said.

“If you look at nutrition labels on many keto ice creams, you’ll see ‘reducing sugar’ or ‘sugar alcohol,’ which are terms for erythritol. You’ll find a typical pint has somewhere between 26 and 45 grams in it,” he said.

“My co-author and I have been going to grocery stores and looking at labels,” Hazen said. “He found a ‘confectionery’ marketed to people with diabetes that had about 75 grams of erythritol.”

There is no firm “accepted daily intake,” or ADI, set by the European Food Safety Authority or the US Food and Drug Administration, which considers erythritol generally recognized as safe (GRAS).

“Science needs to take a deeper dive into erythritol and in a hurry, because this substance is widely available right now. If it’s harmful, we should know about it,” National Jewish Health’s Freeman said.

Hazen agreed: “I normally don’t get up on a pedestal and sound the alarm,” he said. “But this is something that I think we need to be looking at carefully.”

Dementia risk rises if you live with chronic pain, study says | CNN

 — 

Chronic pain, such as arthritis, cancer or back pain, lasting for over three months, raises the risk of cognitive decline and dementia, a new study found.

The hippocampus, a brain structure highly associated with learning and memory, aged by about a year in a 60-year-old person who had one site of chronic pain compared with people with no pain.

When pain was felt in two places in the body, the hippocampus shrank even more — the equivalent of just over two years of aging, according to estimates in the study published Monday in the journal Proceedings of the National Academy of Sciences, or PNAS.

“In other words, the hippocampal (grey matter volume) in a 60-y-old individual with (chronic pain) at two body sites was similar to the volume of (pain free) controls aged 62-y-old,” wrote corresponding author Tu Yiheng and his colleagues. Tu is a professor of psychology at the Chinese Academy of Sciences in Beijing.

The risk rose as the number of pain sites in the body increased, the study found. Hippocampal volume was nearly four times smaller in people with pain in five or more body sites compared with those with only two — the equivalent of up to eight years of aging.

“Asking people about any chronic pain conditions, and advocating for their care by a pain specialist, may be a modifiable risk factor against cognitive decline that we can proactively address,” said Alzheimer’s disease researcher Dr. Richard Isaacson, a preventive neurologist at the Institute for Neurodegenerative Diseases of Florida. He was not involved in the new study.

The study analyzed data from over 19,000 people who had undergone brain scans as part of the UK Biobank, a long-term government study of over 500,000 UK participants between the ages of 40 and 69.

People with multiple sites of body pain performed worse than people with no pain on seven of 11 cognitive tasks, the study found. In contrast, people with only one pain site performed worse on only one cognitive task — the ability to remember to perform a task in the future.

The study controlled for a variety of contributing conditions — age, alcohol use, body mass, ethnicity, genetics, history of cancer, diabetes, vascular or heart problems, medications, psychiatric symptoms and smoking status, to name a few. However, the study did not control for levels of exercise, Isaacson said.

“Exercise is the #1 most powerful tool in the fight against cognitive decline and dementia,” he said via email. “People affected by multisite chronic pain may be less able to adhere to regular physical activity as one potential mechanism for increased dementia risk.”

Equally important is a link between chronic pain and inflammation, Isaacson said. A 2019 review of studies found pain triggers immune cells called microglia to create neuroinflammation that may lead to changes in brain connectivity and function.

People with higher levels of pain were also more likely to have reduced gray matter in other brain areas that impact cognition, such as the prefrontal cortex and frontal lobe — the same areas attacked by Alzhemier’s disease. In fact, over 45% of Alzheimer’s patients live with chronic pain, according to a 2016 study cited by the review.

The study was also not able to determine sleep deficits — chronic pain often makes getting a good night’s sleep difficult. A 2021 study found sleeping less than six hours a night in midlife raises the risk of dementia by 30%.

Globally, low back pain is a leading cause of years lived with disability, with neck pain coming in at No. 4, according to the 2016 Global Burden of Disease Study. Arthritis, nerve damage, pain from cancer and injuries are other leading causes.

Researchers estimate over 30% of people worldwide suffer with chronic pain: “Pain is the most common reason people seek health care and the leading cause of disability in the world,” according to articles published in the journal The Lancet in 2021.

In the United States alone, at least 1 in 5 people, or some 50 million Americans, live with long-lasting pain, according to the US Centers for Disease Control and Prevention.

Nearly 11 million Americans suffer from high-impact chronic pain, defined as pain lasting over three months that’s “accompanied by at least one major activity restriction, such as being unable to work outside the home, go to school, or do household chores,” according to the National Center for Complementary and Integrative Health.

Chronic pain has been linked to anxiety, depression, restrictions in mobility and daily activities, dependence on opioids, increased health care costs, and poor quality of life. A 2019 study estimated about 5 million to 8 million Americans were using opioids to manage chronic pain.

Pain management programs typically involve a number of specialists to find the best relief for symptoms while providing support for the emotional and mental burden of pain, according to John Hopkins Medicine.

Medical treatment can include over-the-counter and prescription medications to stop the pain cycle and ease inflammation. Injections of steroids may also help. Antidepressants increase the amount of serotonin, which controls part of the pain pathway in the brain. Applying brief bursts of electricity to the muscles and nerve endings is another treatment.

Therapies such as massage and whirlpool immersion and exercises may be suggested by occupational and physical therapists. Hot and cold treatments and acupuncture may help as well.

Psychologists who specialize in rehabilitation may recommend cognitive and relaxation techniques such as meditation, tai chi and yoga that can take the mind off fixating on pain. Cognitive behavioral therapy is a key psychological treatment for pain.

Going on an anti-inflammatory diet may be suggested, such as cutting back on trans fats, sugars and other processed foods. Weight loss may be helpful as well, especially for back and knee pain, according to Johns Hopkins.

Alcohol and dementia: Study finds benefits in minimal drinking, but it’s complicated | CNN

 — 

Keeping alcohol consumption to one or two drinks a day lessened the odds of developing dementia, according to a study of nearly 4 million South Koreans.

However, drinking more than two drinks a day increased that risk, according to the study published Monday in the journal JAMA Network Open.

“We found that maintaining mild to moderate alcohol consumption as well as reducing alcohol consumption from a heavy to moderate level were associated with a decreased risk of dementia,” said first author Dr. Keun Hye Jeon, an assistant professor at CHA Gumi Medical Center, CHA University in Gumi, South Korea, in an email.

But don’t rush to the liquor store, experts say.

“This study was well done and is extremely robust with 4 million subjects, but we should be cautious not to over interpret the findings,” said Alzheimer’s researcher Dr. Richard Isaacson, a preventive neurologist at the Institute for Neurodegenerative Diseases of Florida. He was not involved in the new study.

Alcohol use can be a risk factor for breast and other cancers, and consuming too much can contribute to digestive problems, heart and liver disease, hypertension, stroke, and a weak immune system over time, according to the US Centers for Disease Control and Prevention.

There are red flags for Alzheimer’s as well. For example, if a person has one or two copies of the APOE4 gene variant, which raises your risk of developing the mind-wasting disease, drinking is not a good choice, Isaacson said.

“Alcohol has been shown to be harmful for brain outcomes in people with that risk gene — and about 25% of the US population carries one copy of APOE4,” he said.

The new study examined the medical records of people covered by the Korean National Health Insurance Service (NHIS), which provides a free health exam twice a year to insured South Koreans who are 40 and older. In addition to doing various tests, examiners asked about each person’s drinking, smoking and exercise habits.

The study looked at the data collected in 2009 and 2011 and categorized people by their self-reported drinking levels. If a person said they drank less than 15 grams (approximately 0.5 ounces) of alcohol a day, they were considered “mild” drinkers.

In the United States, a standard drink contains 14 grams of alcohol, which is roughly the same as 12 ounces of regular beer, 5 ounces of wine or 1.5 ounces of distilled spirits.

If study participants told doctors they drank 15 to 29.9 grams a day — the equivalent of two standards drinks in the US — the researchers categorized them as “moderate” drinkers. And if people said they drank over 30 grams, or three or more drinks a day, researchers considered them “heavy” drinkers.

Researchers also looked at whether people sustained or changed the amount they drank between 2009 and 2011, Jeon said.

“By measuring alcohol consumption at two time points, we were able to study the relationship between reducing, ceasing, maintaining and increasing alcohol consumption and incident dementia,” he said.

The team then compared that data to medical records in 2018 — seven or eight years later — to see if anyone studied had been diagnosed with dementia.

After adjusting for age, sex, smoking, exercise level and other demographic factors, researchers found people who said they drank at a mild level over time — about a drink a day — were 21% less likely to develop dementia than people who never drank.

People who said they continued to drink at moderate level, or about two drinks a day, were 17% less likely to develop dementia, the study found.

“One has to be cautious when interpreting studies using medical records. They can be fraught with challenges in how diseases are coded and studied,” Isaacson said. “Any anytime you ask people to recall their behaviors, such as drinking, it leaves room for memory errors.”

The positive pattern did not continue as drinking increased. People who drank heavily — three or more drinks a day — were 8% more likely to be diagnosed with dementia, the study found.

If heavy drinkers reduced their drinking over time to a moderate level, their risk of being diagnosed with Alzheimer’s fell by 12%, and the risk of all-cause dementia fell by 8%.

However, people aren’t very good at judging how much alcohol they are drinking, Isaacson said.

“People don’t really monitor their pours of wine, for example,” Isaacson said. “They may think they are drinking a standard-sized glass of wine, but it’s really a glass and a half every time. Drink two of those pours and they’ve had three glasses of wine. That’s no longer mild or moderate consumption.”

In addition, too many people who think they are moderate drinkers do all of their drinking on weekends. Binge drinking is on the rise worldwide, even among adults, studies show.

“If someone downs five drinks on Saturday and Sunday that’s 10 drinks a week so that would qualify as a moderate alcohol intake,” Isaacson said. “To me, that is not that is not the same as having a glass of wine five days a week with a meal, which slows consumption.”

The new study also found that starting to drink at a mild level was associated with a decreased risk of all-cause dementia and Alzheimer’s, “which, to our knowledge, has never been reported in previous studies,” the authors wrote.

However, “none of the existing health guidelines recommends starting alcohol drinking,” Jeon said, adding that since the study was observational, no cause and effect can be determined.

“Our findings regarding a initiation of mild alcohol consumption cannot be directly translated into clinical recommendations, thereby warranting additional studies to confirm these associations further,” Jeon said.

A study published in March 2022 found that just one pint of beer or glass of wine a day can shrink the overall volume of the brain, with the damage increasing as the number of daily drinks rises.

On average, people between 40 and 69 who drank a pint of beer or 6-ounce glass of wine per day for a month had brains that appeared two years older than those who only drank half of a beer, according to that previous study.

“I’ve never personally suggested someone to start drinking moderate amounts of alcohol if they were abstinent,” Isaacson said. “But there’s really not a one-size-fits-all approach towards counseling a patient on alcohol consumption.”

Weight loss surgery extends lives, study finds | CNN

 — 

Weight loss surgery reduces the risk of premature death, especially from such obesity-related conditions as cancer, diabetes and heart disease, according to a new 40-year study of nearly 22,000 people who had bariatric surgery in Utah.

Compared with those of similar weight, people who underwent one of four types of weight loss surgery were 16% less likely to die from any cause, the study found. The drop in deaths from diseases triggered by obesity, such as heart disease, cancer and diabetes, was even more dramatic.

“Deaths from cardiovascular disease decreased by 29%, while deaths from various cancers decreased by 43%, which is pretty impressive,” said lead author Ted Adams, an adjunct associate professor in nutrition and integrative physiology at the University of Utah’s School of Medicine.

“There was also a huge percentage drop — a 72% decline — in deaths related to diabetes in people who had surgery compared to those who did not,” he said. One significant downside: The study also found younger people who had the surgery were at higher risk for suicide.

The study, published Wednesday in the journal Obesity, reinforces similar findings from earlier research, including a 10-year study in Sweden that found significant reductions in premature deaths, said Dr. Eduardo Grunvald, a professor of medicine and medical director of the weight management program at the University of California San Diego Health.

The Swedish study also found a significant number of people were in remission from diabetes at both two years and 10 years after surgery.

“This new research from Utah is more evidence that people who undergo these procedures have positive, beneficial long-term outcomes,” said Grunvald, who coauthored the American Gastroenterological Association’s new guidelines on obesity treatment.

The association strongly recommends patients with obesity use recently approved weight loss medications or surgery paired with lifestyle changes.

“And the key for patients is to know that changing your diet becomes more natural, more easy to do after you have bariatric surgery or take the new weight loss medications,” said Grunvald, who was not involved in the Utah study.

“While we don’t yet fully understand why, these interventions actually change the chemistry in your brain, making it much easier to change your diet afterwards.”

Despite the benefits though, only 2% of patients who are eligible for bariatric surgery ever get it, often due to the stigma about obesity, said Dr. Caroline Apovian, a professor of medicine at Harvard Medical School and codirector of the Center for Weight Management and Wellness at Brigham and Women’s Hospital in Boston. Apovian was the lead author for the Endocrine Society’s clinical practice guidelines for the pharmacological management of obesity.

Insurance carriers typically cover the cost of surgery for people over 18 with a body mass index of 40 or higher, or a BMI of 35 if the patient also has a related condition such as diabetes or high blood pressure, she said.

“I see patients with a BMI of 50, and invariably I will say, ‘You’re a candidate for everything — medication, diet, exercise and surgery.’ And many tell me, ‘Don’t talk to me about surgery. I don’t want it.’ They don’t want a surgical solution to what society has told them is a failure of willpower,” she said.

“We don’t torture people who have heart disease: ‘Oh, it’s because you ate all that fast food.’ We don’t torture people with diabetes: ‘Oh, it’s because you ate all that cake.’ We tell them they have a disease, and we treat it. Obesity is a disease, too, yet we torture people with obesity by telling them it’s their fault.”

Most of the people who choose bariatric surgery — around 80% — are women, Adams said. One of the strengths of the new study, he said, was the inclusion of men who had undergone the procedure.

“For all-causes of death, the mortality was reduced by 14% for females and by 21% for males,” Adams said. In addition, deaths from related causes, such as heart attack, cancer and diabetes, was 24% lower for females and 22% lower for males who underwent surgery compared with those who did not, he said.

Four types of surgery performed between 1982 and 2018 were examined in the study: gastric bypass, gastric banding, gastric sleeve and duodenal switch.

Gastric bypass, developed in the late 1960s, creates a small pouch near the top of the stomach. A part of the small intestine is brought up and attached to that point, bypassing most of the stomach and the duodenum, the first part of the small intestine.

In gastric banding, an elastic band that can be tightened or loosened is placed around the top portion of the stomach, thus restricting the volume of food entering the stomach cavity. Because gastric banding is not as successful in creating long-term weight loss, the procedure “is not as popular today,” Adams said.

“The gastric sleeve is a procedure where essentially about two-thirds of the stomach is removed laparoscopically,” he said. “It takes less time to perform, and food still passes through the much-smaller stomach. It’s become a very popular option.”

The duodenal switch is typically reserved for patients who have a high BMI, Adams added. It’s a complicated procedure that combines a sleeve gastrectomy with an intestinal bypass, and is effective for type 2 diabetes, according to the Cleveland Clinic.

One alarming finding of the new study was a 2.4% increase in deaths by suicide, primarily among people who had bariatric surgery between the ages of 18 and 34.

“That’s because they are told that life is going to be great after surgery or medication,” said Joann Hendelman, clinical director of the National Alliance for Eating Disorders, a nonprofit advocacy group.

“All you have to do is lose weight, and people are going to want to hang out with you, people will want to be your friend, and your anxiety and depression are going to be gone,” she said. “But that’s not reality.”

In addition, there are postoperative risks and side effects associated with bariatric surgery, such as nausea, vomiting, alcoholism, a potential failure to lose weight or even weight gain, said Susan Vibbert, an advocate at Project HEAL, which provides help for people struggling with eating disorders.

“How are we defining health in these scenarios? And is there another intervention — a weight neutral intervention?” Vibbert asked.

Past research has also shown an association between suicide risk and bariatric surgery, Grunvald said, but studies on the topic are not always able to determine a patient’s mental history.

“Did the person opt for surgery because they had some unrealistic expectations or underlying psychological disorders that were not resolved after the surgery? Or is this a direct effect somehow of bariatric surgery? We can’t answer that for sure,” he said.

Intensive presurgery counseling is typically required for all who undergo the procedure, but it may not be enough, Apovian said. She lost her first bariatric surgery patient to suicide.

“She was older, in her 40s. She had surgery and lost 150 pounds. And then she put herself in front of a bus and died because she had underlying bipolar disorder she had been self-medicating with food,” Apovian said. “We as a society use a lot of food to hide trauma. What we need in this country is more psychological counseling for everybody, not just for people who undergo bariatric surgery.”

Managing weight is a unique process for each person, a mixture of genetics, culture, environment, social stigma and personal health, experts say. There is no one solution for all.

“First, we as a society must consider obesity as a disease, as a biological problem, not as a moral failing,” Grunvald said. “That’s my first piece of advice.

“And if you believe your life is going to benefit from treatment, then consider evidence-based treatment, which studies show are surgery or medications, if you haven’t been able to successfully do it with lifestyle changes alone.”

 — 

The death of a participant in a clinical trial of an antibody treatment for Alzheimer’s disease, which is now under consideration by the US Food and Drug Administration, may be linked to the experimental drug, a new report shows.

The research letter, published Wednesday in the New England Journal of Medicine, shares details about what happened to the participant in the open-label extension phase of the trial of lecanemab.

In an open-label extension, there is no placebo arm; rather, all the participants get the medication in question because an earlier part of the trial has shown so much potential.

In this case, a 65-year-old who was in the early stages of Alzheimer’s was taken to an emergency room in a Chicago-area hospital within 30 minutes of the first signs of a stroke, the report says. Doctors at the Northwestern University Feinberg School of Medicine learned that the patient had gotten infusions of lecanemab four days before.

This patient is not the only one to die during the open-arm extension. The health publication Stat reported that an investigator told it about the death of another participant who had bleeding in the brain that may have been related to the drug. In that case, drugmaker Eisai pointed to other possible factors.

Lecanemab is meant to slow the progression of Alzheimer’s. In November, the company released a study showing that it slowed the progression of cognitive decline by 27% compared with a placebo. It also reduced amyloid levels – a protein that is one of the hallmarks of Alzheimer’s – and had positive effects on cognition and the ability to perform everyday tasks when compared with a placebo.

The research also showed that about 2.8% of trial participants who took the drug had a symptomatic side effect called ARIA-E, which involves swelling in the brain. None of the participants who got a placebo had that.

The new report says the medical team at the hospital gave the patient a common medication to break up blood clots that could cause a stroke, called t-PA bolus. Nothing in the patient’s medical background suggested that they would have a problem with that drug. But less than an hour into the treatment, their blood pressure shot up, so doctors stopped the infusion.

A CT scan showed extensive bleeding in the brain.

The doctors then administered a medicine that can control the bleeding, but the patient became severely agitated and developed communication problems. The patient also had frequent nonconvulsive seizures.

The medical team was able to treat the seizures, but the person’s condition did not get better.

After three days in the hospital, the person got a tube in their windpipe to help them breathe. Even with that and other supportive care, the patient died.

An autopsy showed that the patient had extensive brain bleeding and amyloid deposits within many of the blood vessels in their brain that probably contributed to the hemorrhage, the report said.

Essentially, the report says, the blood vessels in the patient’s brain must have burst after being exposed to the blood clot medicine t-PA.

“The extensive number and variation in sizes of the cerebral hemorrhages in this patient would be unusual as a complication of t-PA solely related to cerebrovascular amyloid,” the report says. But the combination of the clot-busting drug with lecanemab may have led to the cerebral hemorrhages.

Northwestern Medicine declined CNN’s request to interview the authors of the new report but said in a statement that it was “an effort to provide relevant data to the medical and scientific community.”

Eisai said it did not have an official response because of patient privacy.

The company and Northwestern Medicine pointed to a response published alongside the new report from clinicians and researchers who were involved in the lecanemab clinical trials.

Drs. Marwan Sabbagh and Christopher H. van Dyck wrote in that response that they “agree that this case raises important management issues for patients with Alzheimer’s disease.”

It is an “unusual case, and we understand why the authors want to highlight a potential concern,” they said.

Their response also pointed to other potential factors in the deaths of both trial participants.

In this case, the brain bleed could have been connected to a period of time after the stroke when the patient’s blood pressure was exceptionally high, they said. And the other trial participant was taking a drug for atrial fibrillation that may have been a contributing factor.

The doctors also write in the response that other patients who have gotten t-PA have died with these amyloid deposits within blood vessels in the brain.

Dr. Sharon Cohen, a behavioral neurologist who works with Alzheimer’s patients at the Toronto Memory Program and an investigator in the lecanemab trial, says it’s been difficult to develop a therapeutic for Alzheimer’s.

Cohen said that doctors have known for years that almost all of the drugs in this class can come with a side effect of ARIA, which stands for amyloid-related imaging abnormalities.

The safety of the drug “looks very acceptable,” she said. “It’s within the range of adverse events that we expected and seems very reasonable for this patient population.”

The rate of bleeding in the trial is considered very low, and most of the microbleeds seen in the trial have been asymptomatic, she said.

In the case of the patient in the new report, Cohen thinks the death was probably related to the blood clot drug but said the combination of that drug and lecanemab “gives us pause.”

If the FDA approves the treatment, there may be some discretion in terms of patient choice and what the prescribing physician feels is best for for someone who is taking anticoagulants or has other risk factors for hemorrhaging, she said.

In general, lecanemab has in many ways exceeded our expectations, she said, “because we haven’t seen such consistently positive results in an Alzheimer’s disease modification trial at all until now.”

1 in 10 Americans over 65 have dementia, study finds | CNN

CNN
 — 

One in 10 Americans over 65 had dementia, while 22% experienced mild cognitive impairment, the earliest stage of the slow slide into senility, according to a new study conducted between 2016 and 2017.

The research, which the authors said is the first nationally representative examination of cognitive impairment prevalence in more than 20 years, was able to measure prevalence of dementia and mild cognitive impairment by age, education, ethnicity, gender and race.

The results showed older adults who self-identified as Black or African American were more likely to have dementia, while those who identify as Hispanic were more likely to suffer from mild cognitive impairment. People who had less than a high school education were more likely to have both conditions.

“Dementia research in general has largely focused on college-educated people who are racialized as white,” lead study author Jennifer Manly said in a statement.

“This study is representative of the population of older adults and includes groups that have been historically excluded from dementia research but are at higher risk of developing cognitive impairment because of structural racism and income inequality,” said Manly, professor of neuropsychology at the Gertrude H. Sergievsky Center and the Taub Institute for Research on Alzheimer’s Disease and the Aging Brain at Columbia University.

“If we’re interested in increasing brain health equity in later life, we need to know where we stand now and where to direct our resources,” Manly said.

The study, published Monday in the journal JAMA Neurology, analyzed data from in-depth neuropsychological tests and interviews with nearly 3,500 people over age 65 enrolled in the Health and Retirement Study, a long-term research project sponsored by the National Institute on Aging and the Social Security Administration.

The research was based on a randomly selected sample of people from the study that completed the core survey and underwent neurological testing between June 2016 and October 2017.

Fifteen percent of people who identified as Black tested positive for dementia, while 22% had mild cognitive decline, the study found. Ten percent of people who identified as Hispanic had dementia, but the rate of milder issues was higher — 28% tested positive for mild cognitive impairment. Nine percent of White people had dementia, while 21% had mild cognitive impairment.

Educational achievement, which experts consider to be protective against cognitive decline, showed a significant divide: Nine percent of people with a college degree tested positive for dementia, compared with 13% of those who never received a high school diploma. Twenty-one percent of people over 65 with college degrees had mild cognitive decline, compared with 30% of those with less than a high school degree.

The extreme elderly had the highest rates of dementia and mild cognitive impairment. Only 3% of adults between 65 and 69 tested positive for dementia, compared with 35% of those 90 and older.

In fact, every five-year increase in age was associated with higher risk of dementia and mild cognitive impairment, the report said. The study, however, found no differences between men and women in rates of either condition

Symptoms of mild cognitive impairment can include losing items, forgetting to do things or go to appointments, or struggling to come up with words. A loss of smell and taste and movement issues can also be symptoms, according to the National Institute on Aging.

People with mild cognitive impairment are fully capable of taking care of themselves, “but what they have to go through to do so is exhausting,” Laura Baker, a professor of gerontology and geriatric medicine at Wake Forest University School of Medicine in Winston-Salem, North Carolina, told CNN in an earlier interview. She was not involved in the current study.

People with mild cognitive impairment may not remember where they are supposed to be, Baker said. ” ‘Let me check my calendar. Oh, I forgot to write on this calendar. Let’s check another calendar. Oh, I can’t find that calendar. I’ve lost my phone. Where is the key? I can’t find the key.’ They’re able to regroup in the early stages and accomplish things, but the toll is immense.”

Not everyone with mild cognitive impairment goes on to develop dementia, although many do, experts say. Lifestyle changes may be a key to reversing mental decline. A 2019 study found personalized lifestyle interventions -— such as diet, exercise, stress reduction and sleep hygiene — not only stopped cognitive decline in people at risk for Alzheimer’s, but actually increased their memory and thinking skills over 18 months. Women responded better than men, a follow-up study found.

A February study found about a third of women 75 years or older with mild cognitive impairment reversed their progression to dementia at some point during follow-up. All of the women, however, had high levels of education and academic performance and excellent written language skills, or what experts call “cognitive reserve.”

Signs of dementia can differ from one person to the next, and can include memory loss and confusion, difficulty speaking, understanding and expressing thoughts, or reading and writing, according to the National Institutes of Health.

People with dementia can act impulsively or show poor judgment, and they can have trouble paying bills or handling money responsibly. They may repeat questions, use strange words to refer to familiar objects and take longer than usual to complete daily tasks.

Wandering and getting lost in a familiar neighborhood is another sign of dementia, as is losing interest in daily activities or events or acting as if they don’t care about other people’s feelings. They may lose their balance or have other problems with movement. At times, people with dementia can hallucinate or experience delusions or paranoia.

Alzheimer’s disease is the most well-known cause of dementia, but cognitive issues can be caused by vascular problems that block the flow of blood to the brain or via ministrokes caused by tiny blood clots traveling to the brain. Frontal lobe dementia, a rare form thought to be associated with abnormal amounts of the proteins tau and TDP-43, often begins in people younger than 60. Another type of decline, called Lewy body dementia, is thought to be caused by abnormal deposits of the protein alpha-synuclein, which are called Lewy bodies.

A person with signs of cognitive decline or dementia needs a full workup by a neurologist to determine the underlying cause, the NIH said. Side effects from a number of medications can mimic dementia, as can certain diseases, such as Huntington’s disease.

If you’ve just been diagnosed with dementia, continue to meet with doctors and specialists and consider asking for a referral to a memory clinic, according to the National Institutes of Health. Reach out to your local Alzheimer’s Disease Research Center and consider joining a clinical trial.

The Alzheimer’s Association has detailed information on the differences between dementia and Alzheimer’s, and it offers many levels of support for both patients and caregivers.

Work on staying healthy — exercise helps with mood, balance and thinking, while eating a well-balanced diet and getting quality sleep can improve the brain’s ability to function.
