A new study suggests that a healthy diet initiated by women before conception could lower the risk of obesity in the offspring.

Childhood obesity is a major public health concern in the United Kingdom, with nearly a quarter of children under 5 and more than a third of children starting secondary school being overweight or obese. Furthermore, childhood obesity is likely to persist in adulthood and have long-term health consequences.

Researchers at the University of Southampton (England) analyzed dietary data of 2,963 mother-child dyads identified from the U.K. Southampton Women’s Survey. Using the dietary data, each mother-child dyad was assigned combined diet quality score, based on which they were categorized into 5 groups: poor, poor-medium, medium, medium-better and best. Childhood adiposity was evaluated using dual-energy x-ray absorptiometry (DXA) and body mass index (BMI) z-scores.

The findings, published in the International Journal of Obesity, showed that mother-offspring diet quality trajectories were stable from preconception in mothers to age 8-9 years in the offspring. A poorer diet quality trajectory was linked to higher prepregnancy maternal BMI, lower maternal age at birth, lower educational levels, smoking, and multiparity. 

After adjusting for confounders, a 1-category reduction in the dietary trajectory was associated with higher DXA percentage body fat (standard deviation, 0.08; 95% confidence interval, 0.01-0.15) and BMI z-score (SD, 0.08; 95% CI, 0.00-0.16) in the offspring aged 8-9 years.

Lead author Sarah Crozier, PhD, University of Southampton, said: “This research shows the importance of intervening at the earliest possible stage in a child’s life, in pregnancy or even before conception, to enable us to tackle it.” The authors believe that the preconception period serves as a crucial window to introduce favorable changes in the maternal dietary quality.

The research was funded by grants from the Medical Research Council, Project EarlyNutrition, and the European Union’s Seventh Framework and Horizon 2020 programs. The study also received support from National Institute for Health Research Southampton Biomedical Research Centre, the University of Southampton and University Hospital Southampton NHS Foundation Trust. The authors reported no competing interests.

Whenever I get a new patient with type 2 diabetes, who is generally on metformin, one of the very first questions they ask me is, “Can I get off my medication?” Everybody, it seems, who gets diabetes wants to not have diabetes.

So, what does this really mean? What does this mean to me as a clinician? And what does this mean to my patients? The American Diabetes Association recently came out with a consensus statement that defines and interprets the definition of remission in people with type 2 diabetes. Basically, if the hemoglobin A1c is less than 6.5% without diabetes medications for at least 3 months, that’s considered remission.

There are other considerations, such as metabolic surgery, that can lead to remission. But again, such patients should be 3 months post surgery and at least 3 months off diabetes medication. As for a lifestyle intervention, the authors state that remission really happens within about 6 months.

That leads me to wonder: What is remission? Remission really means temporary recovery, so it doesn’t mean a cure. Now, I’m not against curing diabetes. In fact, I’m all for it. But when somebody gets diabetes – and honestly, it doesn’t matter whether it’s type 1 or type 2 – the first thing I think of, and I think the first thing that my patients are taught, is how important it is to have a healthy lifestyle. This healthy lifestyle isn’t just for people with diabetes; it largely means the healthy lifestyle that all of us should follow, one where we eat fewer simple carbs, less processed food, more vegetables, more lean proteins and meats – all of the things that we know we should do. And all of the things that keep us healthy. To some degree, I don’t think you can ever get “remission” from diabetes, because if having diabetes points an individual toward having a healthier lifestyle, I think that’s great.

I think people should exercise more. When it comes to treating diabetes, exercise is key. When you think about obesity, we want to help people who are overweight or obese lose weight as part of their treatment for diabetes. And that doesn’t go away, either.

So, no, people who are diagnosed with diabetes don’t really go into remission if they keep their same old habits and don’t lose weight and don’t exercise. But many people with diabetes can get off medication if they do those things.

However, it’s not true for everybody, and I don’t want people to get unrealistic expectations because I think there are probably about a thousand different subtypes of type 2 diabetes. And I’ve definitely seen people who are lean with type 2 diabetes who don’t respond as well to a lifestyle intervention, or people who are more insulin deficient, who also need medication.

I think it’s really important to frame the expectation that, if remission means going back to the way it was before, when they didn’t have to think about what they ate or whether or not they exercised, that’s not going to happen. I think diabetes should really be a wake-up call that people need to be healthier in terms of their lifestyle habits.

The issue of medication is really an individual one, and I think we need to help patients look for what’s best for the individual, what their targets are, what their goals are. But we also have to think that diabetes isn’t just about glucose.

So remission in terms of the ADA’s definition looks at glucose, but I look at more than glucose. You have to look at lipids and blood pressure. And, as I mentioned earlier, you have to look at whether or not a person has preexisting cardiovascular disease or has the presence of microvascular complications that need to be screened for and treated.

I actually think that, in some ways, the diagnosis of diabetes is helpful simply because it helps put people on a better path to health. I don’t want people to think that remission means that they can go back to unhealthy habits. I really encourage all people to live a healthier lifestyle, and if it leads to improvements in glucose levels and getting off medication, I think that’s wonderful and a worthy goal. But remember, health and meeting one’s targets remain key in the treatment of type 2 diabetes.

In the United States, the risk of death from cancer overall has been continuously dropping since 1991, the American Cancer Society (ACS) noted in its latest report.

There has been an overall decline of 32% in cancer deaths as of 2019, or approximately 3.5 million cancer deaths averted, the report noted.

“This success is largely because of reductions in smoking that resulted in downstream declines in lung and other smoking-related cancers,” lead author Rebecca L. Siegel of the ACS, and colleagues, noted in the latest edition of the society’s annual report on cancer rates and trends.

The paper was published online Jan. 12 in CA: A Cancer Journal for Clinicians.

In particular, there has been a fall in both the incidence of and mortality from lung cancer, largely due to successful efforts to get people to quit smoking, but also from earlier diagnosis at a stage when the disease is far more amenable to treatment, noted the authors.

For example, the incidence of lung cancer declined by almost 3% per year in men between the years 2009 and 2018 and by 1% a year in women. Currently, the historically large gender gap in lung cancer incidence is disappearing such that in 2018, lung cancer rates were 24% higher in men than they were in women, and rates in women were actually higher in some younger age groups than they were in men.

Moreover, 28% of lung cancers detected in 2018 were found at a localized stage of disease compared with 17% in 2004.

Patients diagnosed with lung cancer are also living longer, with almost one-third of lung cancer patients still alive 3 years after their diagnosis compared with 21% a decade ago.

However, lung cancer is still the biggest contributor to cancer-related mortality overall, at a death toll of 350 per day – more than breast, prostate, and pancreatic cancer combined, the authors wrote.

This is 2.5 times higher than the death rate from colorectal cancer (CRC), the second leading cause of cancer death in the United States, they added.

Nevertheless, the decrease in lung cancer mortality accelerated from 3.1% per year between 2010 and 2014 to 5.4% per year during 2015 to 2019 in men and from 1.8% to 4.3% in women. “Overall, the lung cancer death rate has dropped by 56% from 1990 to 2019 in men and by 32% from 2002 to 2019 in women,” Ms. Siegel and colleagues emphasized.

Overall, the ACS projects there will be over 1.9 million new cancer cases and over 600,000 cancer deaths across the United States in 2022.


 

Patterns are changing

With prostate cancer now accounting for some 27% of all cancer diagnoses in men, recent trends in the incidence of prostate cancer are somewhat worrisome, the authors wrote. While the incidence for local-stage disease remained stable from 2014 through to 2018, the incidence of advanced-stage disease has increased by 6% a year since 2011. “Consequently, the proportion of distant-stage diagnoses has more than doubled,” the authors noted, “from a low of 3.9% in 2007 to 8.2% in 2018.”

The incidence of breast cancer among women has been slowly increasing by 0.5% per year since about the mid-2000s. This increase is due at least in part to declines in fertility and increases in body weight among women, the authors suggested. Declines in breast cancer mortality have slowed in recent years, dropping from 1% per year from 2013 to 2019 from 2%-3% per year seen during the 1990s and the early 2000s.

As for CRC, incidence patterns are similar by sex but differ by age. For example, incidence rates of CRC declined by about 2% per year between 2014 and 2018 in individuals 50 years and older, but they increased by 1.5% per year in adults under the age of 50. Overall, however, mortality from CRC decreased by about 2% per year between 2010 and 2019, although this trend again masks increasing mortality from CRC among younger adults, where death rates rose by 1.2% per year from 2005 through 2019 in patients under the age of 50.

The third leading cause of death in men and women combined is pancreatic cancer. Here again, mortality rates slowly increased in men between 2000 and 2013 but have remained relatively stable in women.

Between 2010 and 2019, cancers of the tongue, tonsils, and oropharynx caused by human papilloma virus (HPV) increased by about 2% per year in men and by 1% per year in women.

Death from cervical cancer – despite its being one of the most preventable cancers overall – is still the second leading cause of cancer death in women between 20 and 39 years of age. “Most of these women have never been screened so this is low-hanging fruit easily addressed by increasing access to screening and [HPV] vaccination among underserved women,” Ms. Siegel said in a statement.

On the other hand, mortality from liver cancer – having increased rapidly over the past number of decades – appears to have stabilized in more recent years.
 

Survival at 5 years

For all cancers combined, survival at 5 years between the mid-1970s and 2011 through 2017 increased from 50% to 68% for White patients and by 39% to 63% for Black patients. “For all stages combined, survival is highest for prostate cancer (98%), melanoma of the skin (93%) and female breast cancer (90%),” the authors pointed out.

In contrast, survival at 5 years is lowest, at 11% for pancreatic cancer, 20% for cancers of the liver and esophagus, and 22% for lung cancer.

Indeed, for most of the common cancers, cancer survival has improved since the mid-1970s with the exception or uterine and cervical cancer, the latter because there have been few advancements in treatment.

Even among the more rare blood and lymphoid malignancies, improvements in treatment strategies, including the use of targeted therapies, have resulted in major survival gains from around 20% in the mid-1970s for chronic myeloid leukemia (CML) patients to over 70% for CML patients diagnosed between 2011 and 2017.

Similarly, the discovery and use of immunotherapy has doubled 5-year survival rates to 30% for patients with metastatic melanoma from 15% in 2004. On the other hand, racial disparities in survival odds continue to persist. For every cancer type except for cancer of the pancreas and kidney, survival rates were lower for Black patients than for White patients, the researchers pointed out.

“Black individuals also have lower stage-specific survival for most cancer types,” the report authors noted. Indeed, after adjustment for sex, age, and stage at diagnosis, the risk of death is 33% higher in Black patients than White patients and 51% higher in American Indian/Alaska Natives compared to White patients.

That said, the overall incidence of cancer is still highest among White individuals, in part because of high rates of breast cancer in White women, which may in part reflect overdiagnosis of breast cancer in this patient population, as the authors suggested.

“However, Black women have the highest cancer mortality rates – 12% higher than White women,” they observed. Even more striking, Black women have a 4% lower incidence of breast cancer than White women but a 41% higher mortality risk from it.

As for pediatric and adolescent cancers, incidence rates may be increasing slightly among both age groups, but dramatic reductions in death by 71% among children and by 61% among adolescents from the mid-70s until now continue as a singular success story in the treatment of cancer overall.

All the authors are employed by the ACS.

“Black individuals also have lower stage-specific survival for most cancer types,” the report authors noted. Indeed, after adjustment for sex, age, and stage at diagnosis, the risk of death is 33% higher in Black patients than White patients and 51% higher in American Indian/Alaska Natives compared to White patients.

That said, the overall incidence of cancer is still highest among White individuals, in part because of high rates of breast cancer in White women, which may in part reflect overdiagnosis of breast cancer in this patient population, as the authors suggested.

“However, Black women have the highest cancer mortality rates – 12% higher than White women,” they observed. Even more striking, Black women have a 4% lower incidence of breast cancer than White women but a 41% higher mortality risk from it.

As for pediatric and adolescent cancers, incidence rates may be increasing slightly among both age groups, but dramatic reductions in death by 71% among children and by 61% among adolescents from the mid-70s until now continue as a singular success story in the treatment of cancer overall.

In the United States, the risk of death from cancer overall has been continuously dropping since 1991, the American Cancer Society (ACS) noted in its latest report.

There has been an overall decline of 32% in cancer deaths as of 2019, or approximately 3.5 million cancer deaths averted, the report noted.

“This success is largely because of reductions in smoking that resulted in downstream declines in lung and other smoking-related cancers,” lead author Rebecca L. Siegel of the ACS, and colleagues, noted in the latest edition of the society’s annual report on cancer rates and trends.

The paper was published online Jan. 12 in CA: A Cancer Journal for Clinicians.

In particular, there has been a fall in both the incidence of and mortality from lung cancer, largely due to successful efforts to get people to quit smoking, but also from earlier diagnosis at a stage when the disease is far more amenable to treatment, noted the authors.

For example, the incidence of lung cancer declined by almost 3% per year in men between the years 2009 and 2018 and by 1% a year in women. Currently, the historically large gender gap in lung cancer incidence is disappearing such that in 2018, lung cancer rates were 24% higher in men than they were in women, and rates in women were actually higher in some younger age groups than they were in men.

Moreover, 28% of lung cancers detected in 2018 were found at a localized stage of disease compared with 17% in 2004.

Patients diagnosed with lung cancer are also living longer, with almost one-third of lung cancer patients still alive 3 years after their diagnosis compared with 21% a decade ago.

However, lung cancer is still the biggest contributor to cancer-related mortality overall, at a death toll of 350 per day – more than breast, prostate, and pancreatic cancer combined, the authors wrote.

This is 2.5 times higher than the death rate from colorectal cancer (CRC), the second leading cause of cancer death in the United States, they added.

Nevertheless, the decrease in lung cancer mortality accelerated from 3.1% per year between 2010 and 2014 to 5.4% per year during 2015 to 2019 in men and from 1.8% to 4.3% in women. “Overall, the lung cancer death rate has dropped by 56% from 1990 to 2019 in men and by 32% from 2002 to 2019 in women,” Ms. Siegel and colleagues emphasized.

Overall, the ACS projects there will be over 1.9 million new cancer cases and over 600,000 cancer deaths across the United States in 2022.


 

Patterns are changing

With prostate cancer now accounting for some 27% of all cancer diagnoses in men, recent trends in the incidence of prostate cancer are somewhat worrisome, the authors wrote. While the incidence for local-stage disease remained stable from 2014 through to 2018, the incidence of advanced-stage disease has increased by 6% a year since 2011. “Consequently, the proportion of distant-stage diagnoses has more than doubled,” the authors noted, “from a low of 3.9% in 2007 to 8.2% in 2018.”

The incidence of breast cancer among women has been slowly increasing by 0.5% per year since about the mid-2000s. This increase is due at least in part to declines in fertility and increases in body weight among women, the authors suggested. Declines in breast cancer mortality have slowed in recent years, dropping from 1% per year from 2013 to 2019 from 2%-3% per year seen during the 1990s and the early 2000s.

As for CRC, incidence patterns are similar by sex but differ by age. For example, incidence rates of CRC declined by about 2% per year between 2014 and 2018 in individuals 50 years and older, but they increased by 1.5% per year in adults under the age of 50. Overall, however, mortality from CRC decreased by about 2% per year between 2010 and 2019, although this trend again masks increasing mortality from CRC among younger adults, where death rates rose by 1.2% per year from 2005 through 2019 in patients under the age of 50.

The third leading cause of death in men and women combined is pancreatic cancer. Here again, mortality rates slowly increased in men between 2000 and 2013 but have remained relatively stable in women.

Between 2010 and 2019, cancers of the tongue, tonsils, and oropharynx caused by human papilloma virus (HPV) increased by about 2% per year in men and by 1% per year in women.

Death from cervical cancer – despite its being one of the most preventable cancers overall – is still the second leading cause of cancer death in women between 20 and 39 years of age. “Most of these women have never been screened so this is low-hanging fruit easily addressed by increasing access to screening and [HPV] vaccination among underserved women,” Ms. Siegel said in a statement.

On the other hand, mortality from liver cancer – having increased rapidly over the past number of decades – appears to have stabilized in more recent years.
 

Survival at 5 years

For all cancers combined, survival at 5 years between the mid-1970s and 2011 through 2017 increased from 50% to 68% for White patients and by 39% to 63% for Black patients. “For all stages combined, survival is highest for prostate cancer (98%), melanoma of the skin (93%) and female breast cancer (90%),” the authors pointed out.

In contrast, survival at 5 years is lowest, at 11% for pancreatic cancer, 20% for cancers of the liver and esophagus, and 22% for lung cancer.

Indeed, for most of the common cancers, cancer survival has improved since the mid-1970s with the exception or uterine and cervical cancer, the latter because there have been few advancements in treatment.

Even among the more rare blood and lymphoid malignancies, improvements in treatment strategies, including the use of targeted therapies, have resulted in major survival gains from around 20% in the mid-1970s for chronic myeloid leukemia (CML) patients to over 70% for CML patients diagnosed between 2011 and 2017.

Similarly, the discovery and use of immunotherapy has doubled 5-year survival rates to 30% for patients with metastatic melanoma from 15% in 2004. On the other hand, racial disparities in survival odds continue to persist. For every cancer type except for cancer of the pancreas and kidney, survival rates were lower for Black patients than for White patients, the researchers pointed out.

“Black individuals also have lower stage-specific survival for most cancer types,” the report authors noted. Indeed, after adjustment for sex, age, and stage at diagnosis, the risk of death is 33% higher in Black patients than White patients and 51% higher in American Indian/Alaska Natives compared to White patients.

Quebec, Canada’s second most populous province, announced on Jan. 11 that adult residents who refuse to get vaccinated against COVID-19 will face a financial penalty.

The amount hasn’t been decided yet, but it will be “significant” and more than $100. More details will be released at a later date, The Associated Press reported.

“Those who refuse to get their first doses in the coming weeks will have to pay a new health contribution,” Premier Francois Legault said during a news conference.

Not getting vaccinated burdens the health care system, and not all residents should pay for it, he said. About 10% of adults in Quebec are unvaccinated, but they represent about 50% of intensive care patients.

“I think it’s reasonable a majority of the population is asking that there be consequences,” he said. “It’s a question of fairness for the 90% of the population that have made some sacrifices. We owe them.”

The fine will apply to those who don’t qualify for a medical exemption, Mr. Legault said.

Provinces across Canada have reported a surge in COVID-19 cases due to the Omicron variant, with Quebec being one of the hardest-hit, according to Reuters. The province is regularly recording the highest daily case count across the country.

Quebec also has announced a 10 p.m. to 5 a.m. curfew, the AP reported. Starting Jan. 18, liquor and cannabis stores in the province will require proof of vaccination, and shopping malls and hair salons could soon require them as well.

About a quarter of all Canadians live in Quebec, according to CNN. The province was one of the first in Canada to require proof of vaccination for residents to eat in restaurants, go to the gym, or attend sporting events.

Some European countries have announced fees for unvaccinated residents, the AP reported, but Quebec is the first in Canada to announce a financial penalty for those who don’t get a shot.

In Greece, people older than 60 have until Jan. 16 to receive the first dose, or they will be fined 100 euros for every month they remain unvaccinated, the AP reported.

Austria will impose fines up to 3,600 euros for those who don’t follow the vaccine mandate for ages 14 and older, which is slated to start in February.

In Italy, residents who are 50 and older are required to be vaccinated. In mid-February, those who are unvaccinated could be fined up to 1,600 euros if they enter their workplaces, the AP reported.

The CDC is preparing to update its COVID-19 mask recommendations to emphasize the use of N95 and KN95 masks that better filter the virus, Director Rochelle Walensky, MD, said on Jan. 12.

“We are preparing an update to the info on our mask website to best reflect the options that are available to people and the different levels of protection different masks provide, and we want to provide Americans the best and most updated information to choose what mask is going to be right for them,” she said at a White House news briefing.

While the higher-quality masks provide better protection, they can be uncomfortable to wear, expensive, and harder to find. That’s why Dr. Walensky added an important caveat.

“Any mask is better than no mask, and we do encourage all Americans to wear a well-fitting mask to protect themselves and prevent the spread of COVID-19. That recommendation is not going to change,” she said.

“Most importantly, the best mask that you wear is the one you will wear and the one you can keep on all day long and tolerate in public indoor settings.”

Meanwhile, the World Health Organization was more focused on vaccines.

WHO officials stressed on Jan. 12 that global vaccine distribution is first priority in defeating the highly contagious Omicron variant, as well as other variants that may evolve. 

The WHO’s Technical Advisory Group on COVID-19 Vaccine Composition – a group of experts assessing how COVID-19 vaccines perform against Omicron and other emerging variants – says there is an “urgent need” for broader access to vaccines, along with reviewing and updating current vaccines as needed to ensure protection. 

The WHO also disputed the idea that COVID-19 could become endemic in one largely vaccinated nation, while the rest of the world remains unprotected. 

“It is up to us how this pandemic unfolds,” Maria Van Kerkhove, PhD, the WHO’s technical lead on COVID-19 response, said at a news briefing. 

The WHO has a goal of vaccinating 70% of the population of every country by the middle of the year.

But right now, 90 countries have yet to reach 40% vaccination rates, and 36 of those countries have less than 10% of their populations vaccinated, according to WHO Director General Tedros Adhanom Ghebreyesus, PhD.

A staggering 85% of the African population has not received a first dose.

But progress is being made, Dr. Ghebreyesus said at the briefing. 

The WHO said there were over 15 million COVID-19 cases reported last week – the most ever in a single week – and this is likely an underestimate. 

The Omicron variant, first identified in South Africa 2 months ago and now found on all seven continents, is “rapidly replacing Delta in almost all countries,” Dr. Ghebreyesus said.

Dr. Walensky said this week’s U.S. daily average COVID-19 case count was 751,000, an increase of 47% from last week. The average daily hospital admissions this week is 19,800, an increase of 33%. Deaths are up 40%, reaching 1,600 per day.

But she also reported new data that supports other research showing Omicron may produce less severe disease. Kaiser Permanente Southern California released a study on Jan. 11 showing that, compared with Delta infections, Omicron was associated with a 53% reduction in hospitalizations, a 74% reduction in intensive care unit admissions, and a 91% lower risk of death.

In the study, no patients with Omicron required mechanical ventilation. The strain now accounts for 98% of cases nationwide.

But Dr. Walensky warned the lower disease severity is not enough to make up for the sheer number of cases that continue to overwhelm hospital systems.

“While we are seeing early evidence that Omicron is less severe than Delta and that those infected are less likely to require hospitalization, it’s important to note that Omicron continues to be much more transmissible than Delta,” she said. “The sudden rise in cases due to Omicron is resulting in unprecedented daily case counts, sickness, absenteeism, and strains on our health care system.”

People who build up high levels of immune cells from coronaviruses that cause the common cold could have some protection against COVID-19, according to a small study published Jan. 10 in Nature Communications.

Previous studies have shown that T cells created from other coronaviruses can recognize SARS-CoV-2, the virus that causes COVID-19. In the new study, researchers at Imperial College London found that the presence of these T cells at the time of COVID-19 exposure could reduce the chance of getting infected.

The findings could provide a blueprint for a second-generation, universal vaccine to prevent infection from COVID-19 variants, including Omicron and ones that crop up later.

“Being exposed to SARS-CoV-2 virus doesn’t always result in infection, and we’ve been keen to understand why,” Rhia Kundu, PhD, the lead study author from Imperial’s National Heart and Lung Institute, said in a statement.

People with higher levels of T cells from the common cold were less likely to become infected with COVID-19, the researchers found.

“While this is an important discovery, it is only one form of protection, and I would stress that no one should rely on this alone,” Dr. Kundu said. “Instead, the best way to protect yourself against COVID-19 is to be fully vaccinated, including getting your booster dose.”

For the study, Dr. Kundu and colleagues analyzed blood samples from 52 people who lived with someone with confirmed COVID-19 in September 2020. Among the 26 people who didn’t contract COVID-19, there were “significantly higher levels” of preexisting T cells from common cold coronaviruses, as compared with the 26 people who did become infected.

The T cells researched in the study are considered “cross-reactive” and can recognize the proteins of SARS-CoV-2. They offer protection by targeting proteins inside the SARS-CoV-2 virus, rather than the spike proteins on the surface that allow the virus to invade cells.

The current COVID-19 vaccines target the spike proteins, which are more likely to mutate than internal proteins, the researchers wrote. The Omicron variant, for instance, has numerous mutations on spike proteins that may allow it to evade vaccines.

The data suggest that the next step of COVID-19 vaccine development could focus on internal proteins, the researchers said, which could provide lasting protection because T-cell responses persist longer than antibody responses that fade within a few months of vaccination.

“New vaccines that include these conserved, internal proteins would therefore induce broadly protective T-cell responses that should protect against current and future SARS-CoV-2 variants,” Ajit Lalvani, MD, the senior study author and director of Imperial’s respiratory infections health protection research unit, said in the statement.

But more research is needed, the authors said, noting that the study had a small sample size and lacked ethnic diversity, which puts limits on the research.

In the new study, researchers at Imperial College London found that the presence of these T cells at the time of COVID-19 exposure could reduce the chance of getting infected.

The findings could provide a blueprint for a second-generation, universal vaccine to prevent infection from COVID-19 variants, including Omicron and ones that crop up later.

“Being exposed to SARS-CoV-2 virus doesn’t always result in infection, and we’ve been keen to understand why,” Rhia Kundu, PhD, the lead study author from Imperial’s National Heart and Lung Institute, said in a statement.

People with higher levels of T cells from the common cold were less likely to become infected with COVID-19, the researchers found.

“While this is an important discovery, it is only one form of protection, and I would stress that no one should rely on this alone,” Dr. Kundu said. “Instead, the best way to protect yourself against COVID-19 is to be fully vaccinated, including getting your booster dose.”

For the study, Dr. Kundu and colleagues analyzed blood samples from 52 people who lived with someone with confirmed COVID-19 in September 2020. Among the 26 people who didn’t contract COVID-19, there were “significantly higher levels” of preexisting T cells from common cold coronaviruses, as compared with the 26 people who did become infected.

The T cells researched in the study are considered “cross-reactive” and can recognize the proteins of SARS-CoV-2. They offer protection by targeting proteins inside the SARS-CoV-2 virus, rather than the spike proteins on the surface that allow the virus to invade cells.

The current COVID-19 vaccines target the spike proteins, which are more likely to mutate than internal proteins, the researchers wrote. The Omicron variant, for instance, has numerous mutations on spike proteins that may allow it to evade vaccines.

The data suggest that the next step of COVID-19 vaccine development could focus on internal proteins, the researchers said, which could provide lasting protection because T-cell responses persist longer than antibody responses that fade within a few months of vaccination.

“New vaccines that include these conserved, internal proteins would therefore induce broadly protective T-cell responses that should protect against current and future SARS-CoV-2 variants,” Ajit Lalvani, MD, the senior study author and director of Imperial’s respiratory infections health protection research unit, said in the statement.

But more research is needed, the authors said, noting that the study had a small sample size and lacked ethnic diversity, which puts limits on the research.

Some COVID-19 rapid antigen home test kits are much easier to use than others, according to an analysis by ECRI, an independent, nonprofit patient safety organization.

ECRI evaluated seven rapid COVID-19 antigen tests available for purchase online and in retail stores since December.

None of the tests were rated as “excellent” in terms of usability and some had “noteworthy” usability concerns, the company said.

If a test is hard to use, “chances are that you may miss a step or not follow the right order, or contaminate the testing area and that can definitely influence the accuracy of the test and lead to a wrong test result,” Marcus Schabacker, MD, PhD, president and CEO of ECRI, told this news organization.

To gauge usability, ECRI used the “industry-standard” system usability scale (SUS), which rates products on a scale of 0 to 100 with 100 being the easiest to use.

More than 30 points separated the top and bottom tests analyzed. The top performer was On/Go, followed by CareStart and Flowflex.

Doctors providing “fraudulent” COVID-19 information became a hot-button issue for physicians responding to Medscape’s recent article, "Shouldn’t Doctors Who Spread False COVID-19 Information Lose Their Licenses?”

COVID-19 safety recommendations are set by mainstream medical organizations as new information becomes available, but some doctors consistently oppose advice from the Centers for Disease Control and Prevention and other medical authorities. These physicians often promote off-label, unapproved use of medications for COVID-19 and/or contradict mainstream safety guidelines such as vaccines, masks, and social distancing.

Some medical organizations are concerned that these doctors are hampering efforts to control the highly contagious coronavirus and are, at worst, placing lives in danger with their contrarian views that can spread like wildfire on social media sites. Their words are often used by those who refuse to be vaccinated or wear masks.

State licensing boards have mostly refused to discipline these doctors for making false and/or misleading claims, but as the virus spreads, there are calls to take action against them. However, others worry that such actions would violate free speech and critical thought.

Medscape recently took on the question of whether doctors should lose their licenses for spreading misinformation and disinformation about COVID-19, which spurred a strong response from clinician readers.
 

Yes, those doctors are doing wrong

Several physicians took a strong stand against their fellow doctors who are spreading misinformation about COVID-19.

One doctor endorsed the idea of removing licenses for spreading misinformation and called for criminal prosecution: “It should certainly be grounds for cancellation of all licensing (after appropriate examination to rule out acute psychotic episodes, dementia, tumor, etc.) and very likely [include] a charge of manslaughter.”

Another health care provider said, “A person who does not accept science should not, of course, be allowed to practice medicine. One who argues publicly that vaccines and masks don’t work should be prosecuted for crimes ranging from reckless endangerment to attempted murder.”

One reader framed COVID-19 misinformers in stark terms: “These men and women are medical prostitutes. Their medical and surgical colleges [should] have a panel to track in-court testimony and the disinformation they spread ...”

“This is malpractice of the worst kind,” said a clinician. “Public health officials and science are quite clear on [the] best practices for safety during a pandemic, which is killing millions. This is a standard of care.”

“Medical Boards should suspend licenses and give the physician a chance to testify [about] the scientific basis for his comments,” added a health care provider. “Boards involve themselves in all kinds of perceived disciplinary infractions. We are in the midst of a lethal pandemic. I would think that would take precedence over many other issues?”

“I do believe that physicians have the responsibility to speak the truth and have scientifically displayed minds,” said a reader. “Not [to] promulgate misleading, false, and/or unverified information.”

“Any physician, who holds a license, should abide [by] government and state regulation,” asserted a doctor. “He should be disciplined by the board for spreading medical/public misinformation since he is creating potential harm to the population.”

One specialist insisted that “state boards do not do enough to restrict/limit the practice of physicians touting questionable therapies.”

“Any doctor who spreads false information about Covid is hurting our country, our individuals, and our economy and leading to needless deaths,” asserted a physician. “However, there are uncertainties, and where those exist, physicians [should] simply say ‘it is unknown.’”
 

No, those physicians have a right to speak their beliefs

However, many physicians worried that science and controversial thought were being muzzled.

“Absolutely no,” a doctor stated. “Who judges what is misinformation in this age where debate is canceled? Science advances with challenge, and it’s not about an authority dictating the allowable opinion.”

Another clinician claimed the “truth is very difficult to discern from less-than-truth in a country running on a profit-oriented economic ideology.”

One specialist warned that if disinformation doctors are held responsible, then “that means a lot of doctors” will be “gone” because “almost anything that is written or said about COVID can be contested.”

Another physician warned his colleagues about suppressing new ideas: “To condemn what we didn’t try, or purposefully ignore a different approach because [it] doesn’t agree with our opinion is suppression of information.”

Some doctors insisted the issue extended beyond medicine and into Constitutional freedoms. They also expressed their mistrust in the government to regulate physicians.

“There is a First Amendment in this country,” said one reader. “What you think is false may not be so. The people can listen to whoever they want to and make their own medical decisions. We do not need one iota more of politicizing medicine. Having an MD or DO does not mean you relinquish your First Amendment rights.”

“One of the fundamental problems with a system that allows government to ‘license’ physicians, or any other profession, is that politics inevitably turn to cronyism, and big businesses and wealthy people start controlling the government,” argued a doctor.

One clinician suggested enforcement against health food, drug company commercials, and talk shows: “What about all the [misinformation] at the health food stores and the like. Doctors of natural-whatever? Those info-commercials on tv. How many faxes do I get to ‘approve’ because ‘patients request’ braces and pain-treating expensive compounds advertised on TV? We tolerate those ... What about Dr. Oz and the docs on talk shows claiming BS?”
 

And the debate goes even further

Some physicians questioned the very notion of claiming “truth.”

“Nobody should be certain that they have the ‘absolute truth,’” said one reader. “In fact, the best clinical insights exceed so-called knowledge by at least one step.”

“Who can determine exactly what is truth?” asked another clinician. “For sure, the ‘Federal Government,’ who ‘is here to help you,’ is not qualified to make such determinations, and who are you to make such a suggestion as to remove someone’s license because they disagree with you? Give me a break!”

Another physician echoed that sentiment: “What’s true and false is often and certainly currently debatable. There are well-qualified physicians (with credentials such as the development of mRNA technology), virologists, and biostatisticians that have valid thoughts on this but do not necessarily agree with the drug company-sponsored journals and news channels (most of them). Their voices should be heard, and they should not lose their licenses. They are doing their work in good conscience.”

One reader commented that he wanted his “freedom of speech,” and offered this defiant advice: “You can take this license and shove it.”

Finally, a physician noted that the political climate has influenced medical directives: “If someone in a leadership role knowingly, and with intent, spread false information, that is wrong. However, during this global pandemic the active and the politics have combined. Red state no mandate, blue state mandate – what does that tell you about American leadership?”

Medicare intends to limit coverage of the controversial Alzheimer’s drug aducanumab (Aduhelm, Biogen) via a special program intended to help assess how well this exorbitantly expensive medication works, federal officials announced Jan. 11.

On Dec. 20, 2021, Biogen announced a plan to reduce the annual U.S. cost of the drug by 50% – from $56,000 to $28,200 – as Centers for Medicare & Medicaid Services officials were deciding on Medicare’s coverage policy for the medication.

In making its proposed coverage decision, the CMS announced it will pay for aducanumab, a monoclonal antibody, under its coverage-with-evidence-development (CED) mechanism. In making its decision, the CMS approached aducanumab as the first of a potential new class of monoclonal antibodies for the treatment of Alzheimer’s disease. Food and Drug Administration–approved drugs in this class would be covered for those with Medicare only if they are enrolled in qualifying clinical trials, the CMS said. The agency will accept public comments on this decision for 30 days.  

In a statement, CMS Administrator Chiquita Brooks-LaSure said the agency is “committed to providing the American public with a clear, trusted, evidence-based decision that is made only after a thorough analysis of public feedback on the benefits and risks of coverage for Medicare patients.”

As previously reported, the FDA approved aducanumab on June 7, 2021, via an accelerated approval process. The approval, which set off a firestorm of controversy that included resignations of three FDA Peripheral and Central Nervous System Drugs Advisory Committee panel members, was granted based on the medication’s ability to reduce beta-amyloid plaque.

Under the accelerated approval mechanism, Biogen still must deliver solid scientific proof that aducanumab has clinically significant disease-modifying effects. However, the final evidence won’t be in any time soon. In its approval letter, the FDA set a 2030 deadline for a final report on this research.

 

‘Unusual but appropriate’ step

The Medicare decision marks something of a shift in the agency’s approach to paying for medications. On a call with reporters, Tamara Syrek Jensen, JD, director of CMS’ Coverage and Analysis Group, admitted that the agency had taken an “unusual but appropriate” step in trying to set a national policy regarding payment for a drug.

On the same call, Lee Fleisher, MD, CMS’ chief medical officer, addressed the challenges presented by aducanumab, given the serious need for treatments for Alzheimer’s disease. “As a practicing physician, I cannot overemphasize the need to understand the risks and benefits of a given treatment in order to better inform patients and their families,” Dr. Fleisher said. “We do know based on some of the evidence that there may be potential promise with this treatment. That’s why it is critical for us to pursue additional scientific evidence.”

The coverage-with-evidence program will allow Medicare to aid in gathering data, while protecting patients, Dr. Fleisher noted.

“CMS is using its authority provided by Congress to determine if the drug is considered reasonable and necessary, meaning that the benefits of improvement of cognition outweigh the harms in the Medicare population,” Dr. Fleisher said.
 

Biogen disappointed

Cambridge, Mass.–based Biogen urged the CMS to reconsider its approach to payment for aducanumab. In a statement, the company said Medicare should cover “the class of amyloid-directed therapies with the populations studied in the respective clinical trials and guided by expert recommendations for appropriate use.

“We believe Alzheimer’s patients should have access consistent with other therapies with FDA accelerated approval,” Biogen said in the release.

In the company’s view, the CED approach will “significantly limit patient access to an FDA-approved treatment, especially for underserved patients as evidenced in other CED determinations.

“CEDs can take months to years to initiate, and hundreds of Alzheimer’s patients – the majority of whom are Medicare beneficiaries – are progressing each day from mild to moderate disease stages, where treatment may no longer be an option,” Biogen said.

Drug makers had been worried about CMS opting for CED even before the draft decision was unveiled.
 

Others weigh in

BIO, the trade group for biotechnology companies, urged the CMS to provide access to aducanumab without excess restrictions.

There already are concerns among drug makers about CMS efforts “to impose new coverage barriers – and, in particular, coverage with evidence development,” Crystal Kuntz, vice president of policy and research at BIO, and Andy Cosgrove, the organization’s senior director for policy and research, noted in a July 2021 comment about the aducanumab review.

Medicare should instead continue to provide access to medicines for indications that the FDA has approved, with additional flexibility for off-label indications of cancer drugs, they noted. “We believe this should continue to be the case, to ensure that vulnerable Medicare beneficiaries have necessary access to life-altering and lifesaving medications,” the BIO officials wrote.

However, the CMS also received many pleas from physicians asking the agency to limit use of aducanumab at least until there is evidence that it produces a significant clinical benefit.

In a press release, Howard Fillit, MD, cofounder and chief science officer of the Alzheimer’s Drug Discovery Foundation, applauded the decision, describing it as “the right call.

“This decision supports conducting additional clinical trials, which are needed to obtain further insights into the clinical efficacy and safety profile of this drug in real-world populations. This decision has implications for other drugs in this class in late-stage development. If these trials show more clear and robust clinical efficacy, then it is possible the FDA will give these amyloid monoclonal antibodies full approval, and Medicare would be likely to provide full payment,” he added.

In the company’s view, the CED approach will “significantly limit patient access to an FDA-approved treatment, especially for underserved patients as evidenced in other CED determinations.

“CEDs can take months to years to initiate, and hundreds of Alzheimer’s patients – the majority of whom are Medicare beneficiaries – are progressing each day from mild to moderate disease stages, where treatment may no longer be an option,” Biogen said.

Drug makers had been worried about CMS opting for CED even before the draft decision was unveiled.
 

Others weigh in

BIO, the trade group for biotechnology companies, urged the CMS to provide access to aducanumab without excess restrictions.

There already are concerns among drug makers about CMS efforts “to impose new coverage barriers – and, in particular, coverage with evidence development,” Crystal Kuntz, vice president of policy and research at BIO, and Andy Cosgrove, the organization’s senior director for policy and research, noted in a July 2021 comment about the aducanumab review.

Medicare should instead continue to provide access to medicines for indications that the FDA has approved, with additional flexibility for off-label indications of cancer drugs, they noted. “We believe this should continue to be the case, to ensure that vulnerable Medicare beneficiaries have necessary access to life-altering and lifesaving medications,” the BIO officials wrote.

However, the CMS also received many pleas from physicians asking the agency to limit use of aducanumab at least until there is evidence that it produces a significant clinical benefit.

In a press release, Howard Fillit, MD, cofounder and chief science officer of the Alzheimer’s Drug Discovery Foundation, applauded the decision, describing it as “the right call.

“This decision supports conducting additional clinical trials, which are needed to obtain further insights into the clinical efficacy and safety profile of this drug in real-world populations. This decision has implications for other drugs in this class in late-stage development. If these trials show more clear and robust clinical efficacy, then it is possible the FDA will give these amyloid monoclonal antibodies full approval, and Medicare would be likely to provide full payment,” he added.

Medicare intends to limit coverage of the controversial Alzheimer’s drug aducanumab (Aduhelm, Biogen) via a special program intended to help assess how well this exorbitantly expensive medication works, federal officials announced Jan. 11.

On Dec. 20, 2021, Biogen announced a plan to reduce the annual U.S. cost of the drug by 50% – from $56,000 to $28,200 – as Centers for Medicare & Medicaid Services officials were deciding on Medicare’s coverage policy for the medication.

In making its proposed coverage decision, the CMS announced it will pay for aducanumab, a monoclonal antibody, under its coverage-with-evidence-development (CED) mechanism. In making its decision, the CMS approached aducanumab as the first of a potential new class of monoclonal antibodies for the treatment of Alzheimer’s disease. Food and Drug Administration–approved drugs in this class would be covered for those with Medicare only if they are enrolled in qualifying clinical trials, the CMS said. The agency will accept public comments on this decision for 30 days.  

In a statement, CMS Administrator Chiquita Brooks-LaSure said the agency is “committed to providing the American public with a clear, trusted, evidence-based decision that is made only after a thorough analysis of public feedback on the benefits and risks of coverage for Medicare patients.”

As previously reported, the FDA approved aducanumab on June 7, 2021, via an accelerated approval process. The approval, which set off a firestorm of controversy that included resignations of three FDA Peripheral and Central Nervous System Drugs Advisory Committee panel members, was granted based on the medication’s ability to reduce beta-amyloid plaque.

Under the accelerated approval mechanism, Biogen still must deliver solid scientific proof that aducanumab has clinically significant disease-modifying effects. However, the final evidence won’t be in any time soon. In its approval letter, the FDA set a 2030 deadline for a final report on this research.

 

‘Unusual but appropriate’ step

The Medicare decision marks something of a shift in the agency’s approach to paying for medications. On a call with reporters, Tamara Syrek Jensen, JD, director of CMS’ Coverage and Analysis Group, admitted that the agency had taken an “unusual but appropriate” step in trying to set a national policy regarding payment for a drug.

On the same call, Lee Fleisher, MD, CMS’ chief medical officer, addressed the challenges presented by aducanumab, given the serious need for treatments for Alzheimer’s disease. “As a practicing physician, I cannot overemphasize the need to understand the risks and benefits of a given treatment in order to better inform patients and their families,” Dr. Fleisher said. “We do know based on some of the evidence that there may be potential promise with this treatment. That’s why it is critical for us to pursue additional scientific evidence.”

The coverage-with-evidence program will allow Medicare to aid in gathering data, while protecting patients, Dr. Fleisher noted.

“CMS is using its authority provided by Congress to determine if the drug is considered reasonable and necessary, meaning that the benefits of improvement of cognition outweigh the harms in the Medicare population,” Dr. Fleisher said.
 

Biogen disappointed

Cambridge, Mass.–based Biogen urged the CMS to reconsider its approach to payment for aducanumab. In a statement, the company said Medicare should cover “the class of amyloid-directed therapies with the populations studied in the respective clinical trials and guided by expert recommendations for appropriate use.

“We believe Alzheimer’s patients should have access consistent with other therapies with FDA accelerated approval,” Biogen said in the release.

Nearly 1 in 5 women who receive the recommended 10 biennial screening rounds for breast cancer in Norway will get a false positive result, and 1 in 20 women will receive a false positive result that leads to an invasive procedure, a new analysis shows.

While the risk may seem high, it is actually much lower than what researchers have reported in the U.S., the study authors note in their paper, published online Dec. 21 in Cancer.

“I am proud about the low rate of recalls we have in Norway and Europe – and hope we can keep it that low for the future,” said senior author Solveig Hofvind, PhD, head of BreastScreen Norway, a nationwide screening program that invites women aged 50 to 69 to mammographic screening every other year.

“The double reading in Europe is probably the main reason for the lower rate in Europe compared to the U.S., where single reading is used,” she said in an interview.

Until now, Dr. Hofvind and her colleagues say, no studies have been performed using exclusively empirical data to describe the cumulative risk of experiencing a false positive screening result in Europe because of the need for long-term follow-up and complete data registration.

For their study, the researchers turned to the Cancer Registry of Norway, which administers BreastScreen Norway. They focused on data from 1995 to 2019 on women aged 50 to 69 years who had attended one or more screening rounds and could potentially attend all 10 screening examinations over the 20-year period.

Women were excluded if they were diagnosed with breast cancer before attending screening, participated in interventional research, self-referred for screening, were recalled due to self-reported symptoms or technically inadequate mammograms, or declined follow-up after a positive screen.

Among more than 421,000 women who underwent nearly 1.9 million screening examinations, 11.3% experienced at least one false positive result and 3.3% experienced at least one false positive involving an invasive procedure, such as fine-needle aspiration cytology, core-needle biopsy, or open biopsy.

The cumulative risk of experiencing a first false positive screen was 18.0% and that of experiencing a false positive that involved an invasive procedure was 5.01%. Adjusting for irregular attendance, age at screening, or the number of screens attended had little effect on the estimates.

The results closely match earlier findings from Norway that have been based on assumptions rather than exclusively empirical data. However, these findings differ from results reported in U.S. studies, which have relied largely on data from the Breast Cancer Surveillance Consortium, the researchers say.

“The latter have indicated that, for women who initiate biennial screening at the age of 50 years, the cumulative risk after 10 years is 42% for experiencing at least one false-positive screening result and 6.4% for experiencing at least one false-positive screening result involving an invasive procedure,” Dr. Hofvind and her colleagues write.

Several principal investigators with the Breast Cancer Surveillance Consortium did not respond or were unavailable for comment when contacted by this news organization.

However, the study authors highlighted several factors that could help explain the discrepancy between the U.S. and European results.

In addition to double mammogram reading, “European guidelines recommend that breast radiologists read 3,500 to 11,000 mammograms annually, whereas 960 every 2 years are required by the U.S. Mammography Quality Standards Act,” the researchers note. They also point out that previous screening mammograms are readily available in Norway, whereas this is not always the case in the U.S.

“False-positive screening results are a part of the screening for breast cancer – and the women need to be informed about the risk,” Dr. Hofvind concluded. “The screening programs should aim to keep the rate as low as possible for the women [given] the costs.”

The study was supported by the Dam Foundation via the Norwegian Breast Cancer Society.
