A Combination of Three Simple Treatments May Reduce Risk of Invasive Cancer by 61%
TOPICS: Aging Cancer Frontiers Oncology
By FRONTIERS MAY 1, 2022

Researchers have found that a combination of high-dose vitamin D, omega-3s, and a simple home strength exercise program (SHEP) showed a cumulative reduction of 61% in cancer risk in healthy adults aged 70 or older.

A combination of three simple treatments may reduce invasive cancer risk by 61% among adults aged 70+.

New research published in the journal Frontiers in Aging found that a combination of high-dose vitamin D, omega-3 fatty acids, and a simple home strength exercise program (SHEP) reduced cancer risk by 61 percent in healthy persons aged 70 and older. It is the first study to look at the combined benefit of three low-cost public health interventions for the prevention of invasive cancers. Following future studies, the results may influence the future of cancer prevention in older adults.

Cancer is regarded as a major age-related disease in Europe and the US. It is the second leading cause of death in older adults, and the risk of developing most cancers increases with age.

Apart from preventative recommendations such as not smoking and sun protection, public health efforts that focus on cancer prevention are limited, according to Dr Heike Bischoff-Ferrari of the University Hospital Zurich: “Preventive efforts in middle-aged and older adults today are largely limited to screening and vaccination efforts.”

Vitamin D, omega-3, and exerciseMechanistic studies have shown that vitamin D inhibits the growth of cancer cells. Similarly, omega-3 may inhibit the transformation of normal cells into cancer cells, and exercise has been shown to improve immune function and decrease inflammation, which may help in the prevention of cancer

However, there was a lack of robust clinical studies proving the effectiveness of these three simple interventions, alone or combined.

Bischoff-Ferrari and her colleagues wanted to fill these knowledge gaps by testing the effect of daily high-dose vitamin D3 (one form of vitamin D supplements), daily supplemental omega-3s, and a simple home exercise program, alone and in combination, on the risk of invasive cancer among adults aged 70 or older.

A combination of simple treatmentsTo do so, the researchers conducted the DO-HEALTH trial: a three-year trial in five European countries (Switzerland, France, Germany, Austria, and Portugal) with 2,157 participants.

“In DO-HEALTH, our aim was to test promising combined interventions for cancer prevention taking advantage of potentially small additive benefits from several public health strategies,” explained Bischoff-Ferrari. “In fact, novel cancer treatments aim to block multiple pathways for cancer development by combining several agents. We translated this concept into cancer prevention.”

The participants were randomized into eight different groups to test the individual and combined benefit of the interventions: group one received 2,000 IU per day of Vitamin D3 (equivalent to > 200% the amount of current recommendations for older adults, which is 800 IU per day), 1g per day of omega-3s, and three times per week SHEP; group two vitamin D3 and omega-3s; group three vitamin D3 and SHEP; group four omega-3s and SHEP; group five vitamin D3 alone; group six omega-3s alone; group seven SHEP alone; and the last group received a placebo.

Participants received check-up phone calls every three months and had standardized examinations of health and function in the trial centers at baseline, year 1, year 2, and year 3.

Preventing invasive cancerThe results show that all three treatments (vitamin D3, omega-3s, and SHEP) had cumulative benefits on the risk of invasive cancers.

Each of the treatments had a small individual benefit but when all three treatments were combined, the benefits became statistically significant, and the researchers saw an overall reduction in cancer risk by 61%.

“This is the first randomized controlled trial to show that the combination daily vitamin D3, supplemental marine omega-3s, and a simple home exercise program may be effective in the prevention of invasive cancer among generally healthy and active adults aged 70 and older,” Bischoff-Ferrari commented.

The results may impact the future of invasive cancer prevention in older adults. Bischoff-Ferrari concluded: “Our results, although based on multiple comparisons and requiring replication, may prove to be beneficial for reducing the burden of cancer.”

“Future studies should verify the benefit of combined treatments in the prevention of cancer, also extending to longer follow-ups beyond the three-year duration assessed in this trial.”

The Children Left Behind by Long Covid
As the world pretends the pandemic is over, at least a half-million children in the U.S. are struggling with the mysterious disease.

Lincoln Brockmeyer folds his lanky 6-foot-4-inch frame onto the examination table as he explains to the pair of doctors that he feels tapped out, his energy totally sapped. Some days, he says, he needs a nap to make it through the afternoon. Worse than the bone-tired feeling he can’t seem to shake is the constant pain in his legs and the sensation that each one weighs a thousand pounds. He tells the doctors that he’s lost weight—at one point he was down 30 pounds, to 148. He can’t run without getting lightheaded, he says, and every time he stands up he gets deep purple spidery veins on his arms and legs. He loves playing basketball, but not when his body hurts like this.

“I’m trying to stay optimistic,” he says when the doctors inform him he’s got all the signs of long Covid. They’re telling him this in March, and if he wants to get better he needs to take it easy. That means no basketball for a while. Lincoln hates hearing this. Still, they start hatching a plan—something none of the other doctors he’s seen have been able to offer. It’s too late for what would have been his freshman season of high school, but they’re hopeful he’ll be back on the court in time for his sophomore year. “We’ve got you,” says Amy Edwards, a pediatric infectious diseases expert who runs the long-haul Covid clinic at University Hospitals Rainbow Babies & Children’s hospital in Cleveland.

The U.S. and the world are trying to move on from Covid-19. Everyone is tired of even thinking about it. The Centers for Disease Control and Prevention has effectively given up on trying to impose collective measures to control the virus. Even people who’ve been vigilant are ditching their masks. And, yet again, cases are rising in the U.S.

More cases will mean more long Covid, including pediatric long Covid. Estimates of the number of children who face long-term symptoms are far from precise, but they probably range from 5% to 10% of those infected with the virus, says Daniel Griffin, an infectious diseases expert at Columbia University who treats Covid patients and hosts a weekly podcast update on the disease. Even at the lower end of the estimates, that translates to more than a half-million children of the 13 million so far infected. (Studies of infected adults indicate that an estimated 10% to 30% may have long Covid.)

Up until last year, Lincoln, now 15, was a star forward on his middle school basketball team in Cuyahoga Falls, Ohio. So good, in fact, that high school coaches in the area were noticing his talent. In May, Lincoln’s parents moved the family to Copley, a small town west of Akron, so Lincoln could play on a team his parents believed would give him his best shot at success. “I’m going to brag on my kid a little bit,” says his father, Nate, who’s also sitting in the examination room. “He’s a stud basketball player.”

But when Lincoln was handing out Halloween candy last year, he felt cold symptoms coming on. He lay down and drifted into an uneasy sleep. His dad says Lincoln’s fever spiked to 104F and his breathing became labored. Lincoln tried pushing through his basketball tryouts the following week but couldn’t keep up. After missing a few days of school, he forced himself back. But when he noticed blood in his urine, his parents took him to the emergency room. Doctors ran tests over the course of a two-day hospital stay, including a Covid antibody test. The results showed only that Lincoln had had the illness at some point.

He filed through a round of appointments with specialists in oncology, pulmonology, and rheumatology, but none of the doctors could pinpoint a specific reason for his extreme fatigue. He stopped going to school again in November and was barely able to get out of bed until mid-January. One doctor put him on a powerful and potentially dangerous immunosuppressive drug called methotrexate that helped him regain enough energy to resume classes. Another urged his parents to take him to see pediatric long-Covid experts at Rainbow Babies & Children’s hospital. It took more than a month to get an appointment.

“Nobody knew what to do with him. It was very frustrating because I was like, ‘I don’t know what to do at this point. Nobody’s believing me’ ”

There isn’t much known about who gets long Covid or why, which puts it in a frustrating category of mysterious illnesses that occur after infections such as Lyme disease or mononucleosis. The National Institutes of Health is working on answering these questions about long Covid, but the findings won’t be available for at least another two years. And even that research will probably just scratch the surface of understanding. Meanwhile, many pediatricians still don’t take seriously the sometimes amorphous complaints of their young patients, perhaps suspecting they’re merely trying to avoid school. “They’re told, ‘It’s all in your head. You’re just depressed,’?” says David Miller, a pediatric integrative medicine specialist who sees long-Covid patients with Edwards at Rainbow Babies. “But now we have so many of them. Not all the kids are trying to get out of school.”

Even when doctors are attentive, children often can’t or don’t know how to articulate their symptoms. Fatigue is the most prevalent complaint, followed by pain. Difficulty paying attention and altered taste or smell are also common. Doctors who treat children and adolescents say their patients frequently show up with a battery of complaints affecting many different bodily systems, sometimes weeks after a Covid infection and regardless of the severity of the initial symptoms. At Rainbow Babies many children are surprised, as Lincoln was, to discover their stomach muscles hurt when slightly pressed, even when they’ve never noticed abdominal pain before. “The strange thing is how consistent it is,” Edwards says.

Although children generally fare better with Covid than adults, many parents, lulled by flawed CDC guidance and a fire hose of online misinformation from self-appointed experts, have mistakenly assumed the virus poses no more risk to children than a common cold. Many pediatricians, too, have spent the pandemic unconvinced about the utility of testing sick kids for the virus. And only 28% of children age 5 to 11 had been given two doses of a Covid vaccine as of late April, according to the CDC. These factors help explain why pediatric hospitalizations reached a pandemic peak during omicron. Deaths are rare, but that’s scant comfort to the parents of the 1,010 children with Covid who have died in the U.S. And even though that number is far surpassed by adult lives lost, Covid was still the fourth-leading cause of death in kids in January, according to the Kaiser Family Foundation and the Peterson Center on Healthcare.

Not every kid with long Covid has it as severely as Lincoln; some have it much worse. Griffin recalls meeting with a 16-year-old girl who couldn’t sit up for more than a few minutes without throwing up, so her mother took her to a pediatric long-Covid clinic in Colorado. Griffin says the last time he talked with the girl, she could sit up for about 45 minutes without vomiting.

Children suffering from long Covid who are able to get in to see Edwards, Miller, or other doctors at the roughly 75 to 100 children’s hospitals that have set up long-Covid clinics across the country are the lucky ones. These doctors tend to take on the role of support coaches, helping children organize their days and scheduling frequent breaks so they can care for themselves better. They may advise changing diets to cut out white sugar in favor of eating anti-inflammatory fruits and vegetables. Or they may schedule an appointment with a cardiologist, gastroenterologist, or physical therapist.

Some doctors contend that whatever these kids are suffering from, it isn’t long Covid. One outspoken skeptic of long-Covid treatment is Kristen Walsh, a pediatrician in New Jersey who’s convinced doctors are financially motivated to treat a made-up condition. “There’s been a lot of money earmarked for Covid in kids and hospitals to open these clinics,” Walsh says. “Follow the money.” But, like so much heated debate over the pandemic, Walsh’s argument is infused with more emotion than factual accuracy: The NIH has awarded large amounts of money for research on long Covid, but that money doesn’t extend to treatment clinics. Walsh is a founding member of a group that calls itself Urgency of Normal, composed of about a dozen doctors who earlier this year began a noisy campaign to drop pandemic restrictions, particularly masking in schools. They also provide a “toolkit” for parents that minimizes the risks for children. These doctors insist, for instance, that Covid is like the flu for unvaccinated kids and that long Covid is not a major risk.

“It makes me so mad,” says Alexandra Yonts, an infectious diseases physician who runs a pediatric long-Covid clinic at Children’s National Hospital in Washington, D.C. “There have been so many things discounted because kids don’t have a voice.” Children’s National received $40 million from the NIH last year to study the long-term effects of Covid, but the funding is only for research, not the pediatric long-Covid clinic, Yonts says. She spends her off-hours wrangling specialists to meet with patients. She says she was skeptical about post-infection illnesses prior to Covid, but the influx of patients with lingering symptoms coming into the hospital opened her eyes.

Determined parents eventually find their way to Children’s National or one of the other pediatric long-Covid clinics in the U.S. They’re staffed with doctors who, like Yonts, work extra hours to squeeze in long-Covid patients around their regular caseload. That’s increasingly tough to do, because more and more children keep pouring in. Following omicron the number of families seeking help at the long-Covid clinic at Children’s National has swelled. Yonts says the waitlist has stretched to four months. The story is similar across the country. “Post-infection syndromes used to be one here, one there. They weren’t so common,” says Sindhu Mohandas, a pediatric infectious disease specialist who leads the long-Covid clinic at Children’s Hospital Los Angeles. “But now we’re seeing a lot more.” She says her clinic is getting calls from all over the country.

Many children slip through the cracks, though, especially those from Black and Hispanic families. At Children’s National, the clinic primarily sees “affluent, medically literate, White families,” Yonts says, even though Black and Hispanic people in Washington are more likely to have had Covid than Whites. A report out at the end of March, The State of Black America and Covid-19, said there is “already evidence of disparities in diagnosis and access to treatment” regarding long Covid. The group that released the report, the Black Coalition Against Covid, says more efforts are needed to include Black people in trials and treatment programs.

The Rainbow Babies clinic operates much the same way as Children’s National. Edwards was introduced to long Covid through her work on a different Covid-related condition called multisystem inflammatory syndrome in children, or MIS-C. When a nearby medical center wanted to open an adult long-Covid clinic, it sought out Edwards and asked if she could handle any kids who also came in. It wouldn’t be many, she recalls them saying. “I was like, ‘Sure, one or two kids here or there? I can do it.’?”

What started out as a trickle grew into a torrent. Edwards ran into Miller in the hallway one day and asked for his help. They still have more patients than they can handle, especially because they have to squeeze in the 60 cases or so that they’ve seen in the last year around their regular practices. The children they treat usually have ailments complex enough that appointments often take much longer than an hour—compared with standard office visits of 15 to 30 minutes—and they have to return for multiple follow-up visits. It takes about six weeks for a new patient to get an appointment.

At Rainbow Babies, Edwards and Miller see their long-Covid patients every Friday. “I’m sure we’re losing money for the hospital system, because we’re only seeing five patients in a day,” Edwards says.

She’s talking in between seeing patients in a room normally used for psychologists to observe children through a two-way mirror. It’s subdued compared with the bright, happy forest landscapes that cover the walls and ceilings throughout the lobby and hallways of Rainbow Babies. Edwards and Miller see their patients wherever they can find an open spot in a wing of the hospital for specialty care. Edwards does all the administrative work herself. Her own kids know she won’t be home in time for dinner most Fridays.

In early March, Edwards and Miller see their youngest patient. Hunter Reinard, who’s just turned 4, has been sick with long Covid for two of those years. He hides behind a blue chair in the exam room, while his mother, Kristin, explains that after the entire family came down with Covid early in the pandemic, he began suffering from high fevers every few weeks. He wasn’t eating well (he told his mom food smelled “disgusting”) and wasn’t sleeping. Over a course of months, Kristin had taken Hunter to a series of hospitals—including the Cleveland Clinic and, before the long-Covid clinic opened, Rainbow Babies. “Nobody knew what to do with him,” Kristin says to Edwards and Miller. “It was very frustrating because I was like, ‘I don’t know what to do at this point. Nobody’s believing me.’?”

She tells the doctors that Hunter is beginning to gain weight thanks to the PediaSure shakes she’s been giving him. She and her husband also stopped finding Hunter downstairs at 4 in the morning playing with his toys, once they started giving him a melatonin supplement to help him sleep.

But the family all got Covid again in December. In February, Hunter’s on-and-off-again fever hit 106F. He began hallucinating, seeing characters from his favorite video games floating on the ceiling. Kristin says she’s been feeling overwhelmed.

“I want to say, ‘You’re not crazy,’?” Edwards says to her.

“I feel crazy,” Kristin says. “For a year and a half nobody believed me.”

“I believe you,” Edwards says.

Some in the medical community theorize that long Covid is an autoimmune response or that the virus causes nerve damage. But no one knows for sure. At Rainbow Babies, Edwards and Miller tend to prescribe rest and diet changes. Lincoln Brockmeyer says the support and guidance he’s gotten from his doctors have begun to pay off. He’s eating better and is almost back to his pre-Covid weight. He has more energy, too. Getting refined sugar out of his diet has been a “game changer,” he says. He can take longer walks now, and on good days he can’t resist shooting a few hoops. But he has to sit down between shots. “That was the thing that was most disappointing, because I missed my whole basketball season,” he says. “I worked so hard, and it all got thrown away.”

Basketball hasn’t been the only loss for this high school freshman in a brand-new town. Lincoln says he’d just started warming up to people at his school when he got sick. Then he was left to watch on Snapchat all the fun his new friends were having. “I felt really alone,” he says.

He still feels behind in school but says his mental health has improved since the diagnosis. “Now that I feel like we know it is long haul, it feels better to know what I actually have,” he says, “and that we’re able to do something about it.”

Cognitive Impairment From Severe COVID-19 Equivalent to 20 Years of Aging – Losing 10 IQ Points
TOPICS: Aging COVID-19 Infectious Diseases Intelligence Neuroscience University Of Cambridge
By UNIVERSITY OF CAMBRIDGE MAY 8, 2022

According to a team of scientists, cognitive impairment as a result of severe COVID-19 is similar to that sustained from the 20 years of aging between 50 and 70 and is the equivalent of losing 10 IQ points.

Cognitive impairment as a result of severe COVID-19 is similar to that sustained between 50 and 70 years of age and is the equivalent to losing 10 IQ points, say a team of scientists from the University of Cambridge and Imperial College London.

The findings, published recently in the journal eClinicalMedicine, emerge from the National Institute for Health and Care Research (NIHR) COVID-19 BioResource. The results of the study suggest the effects are still detectable more than six months after the acute illness, and that any recovery is at best gradual.

“Cognitive impairment is common to a wide range of neurological disorders, but the patterns we saw – the cognitive ‘fingerprint’ of COVID-19 – was distinct from all of these.” — David Menon


There is mounting evidence that COVID-19 can cause long-term cognitive and mental health issues, with recovered patients reporting symptoms including fatigue, “brain fog,” difficulty recalling words, sleep disturbances, anxiety, and even post-traumatic stress disorder (PTSD) months after infection. In the United Kingdom, a research study found that one in every seven people surveyed reported having symptoms such as cognitive difficulties 12 weeks after a positive COVID-19 test.

While even mild cases can lead to persistent cognitive symptoms, between a third and three-quarters of hospitalized patients report still suffering cognitive symptoms three to six months later.

To investigate this link in greater detail, researchers analyzed data from 46 people who received in-hospital care for COVID-19 at Addenbrooke’s Hospital, part of Cambridge University Hospitals NHS Foundation Trust. During their hospital stay, 16 patients were placed on mechanical ventilation. All of the patients were admitted between March and July of 2020 and were recruited to the NIHR COVID-19 BioResource.

The individuals underwent detailed computerized cognitive tests an average of six months after their acute illness using the Cognitron platform, which measures different aspects of mental faculties such as memory, attention, and reasoning. Scales measuring anxiety, depression, and post-traumatic stress disorder were also assessed. Their data were compared against matched controls.

This is the first time that such rigorous assessment and comparison has been carried out in relation to the aftereffects of severe COVID-19.

COVID-19 survivors were less accurate and with slower response times than the matched control population – and these deficits were still detectable when the patients were following up six months later. The effects were strongest for those who required mechanical ventilation. By comparing the patients to 66,008 members of the general public, the researchers estimate that the magnitude of cognitive loss is similar on average to that sustained with 20 years aging, between 50 and 70 years of age, and that this is equivalent to losing 10 IQ points.

Survivors scored particularly poorly on tasks such as verbal analogical reasoning, a finding that supports the commonly-reported problem of difficulty finding words. They also showed slower processing speeds, which aligns with previous observations post COVID-19 of decreased brain glucose consumption within the frontoparietal network of the brain, responsible for attention, complex problem-solving and working memory, among other functions.

Professor David Menon from the Division of Anaesthesia at the University of Cambridge, the study’s senior author, said: “Cognitive impairment is common to a wide range of neurological disorders, including dementia, and even routine aging, but the patterns we saw – the cognitive ‘fingerprint’ of COVID-19 – was distinct from all of these.”

While it is now well established that people who have recovered from severe COVID-19 illness can have a broad spectrum of symptoms of poor mental health – depression, anxiety, post-traumatic stress, low motivation, fatigue, low mood, and disturbed sleep – the team found that acute illness severity was better at predicting the cognitive deficits.

The patients’ scores and reaction times began to improve over time, but the researchers say that any recovery in cognitive faculties was at best gradual and likely to be influenced by a number of factors including illness severity and its neurological or psychological impacts.

Professor Menon added: “We followed some patients up as late as ten months after their acute infection, so we’re able to see a very slow improvement. While this was not statistically significant, it is at least heading in the right direction, but it is very possible that some of these individuals will never fully recover.”

There are several factors that could cause the cognitive deficits, say the researchers. Direct viral infection is possible, but unlikely to be a major cause; instead, it is more likely that a combination of factors contribute, including inadequate oxygen or blood supply to the brain, blockage of large or small blood vessels due to clotting, and microscopic bleeds. However, emerging evidence suggests that the most important mechanism may be damage caused by the body’s own inflammatory response and immune system.

While this study looked at hospitalized cases, the team say that even those patients not sick enough to be admitted may also have tell-tale signs of mild impairment.

Professor Adam Hampshire from the Department of Brain Sciences at Imperial College London, the study’s first author, said: “Around 40,000 people have been through intensive care with COVID-19 in England alone and many more will have been very sick, but not admitted to hospital. This means there is a large number of people out there still experiencing problems with cognition many months later. We urgently need to look at what can be done to help these people.”

Professor Menon and Professor Ed Bullmore from Cambridge’s Department of Psychiatry are co-leading working groups as part of the COVID-19 Clinical Neuroscience Study (COVID-CNS) that aim to identify biomarkers that relate to neurological impairments as a result of COVID-19, and the neuroimaging changes that are associated with these.
