Analysis of doctors’ EHR email finds infrequent but notable hostility
Among the emails, 43% were from patients; the remainder were mostly from other physicians or clinicians, or automated. The content of the messages wasn’t associated with doctor burnout, as the researchers had hypothesized. And only about 5% of the messages had negative sentiment.
But the researchers were struck by the hostility of that sentiment, displayed in messages like these that surely would be distressing for physicians to read:
“I hope and expect that you will spend eternity in he**. You are an abusive, nasty, cheap person.”
“Your office is full of liars, hypocrites and I will do everything in my power to prevent anyone from going to your bullsh** office again.”
About 5% of emails had an overall negative sentiment, with high-frequency words like “cancel,” “pain,” or “problem.” Among patient messages, 3% were negative and contained words and expletives suggesting hatred, hostility, or violence.
“F***” was the most common expletive used by patients.
Researchers provided examples of profanity-laced messages, including one patient who said, “I am so upset that I was told the blood work would include the gender of the baby. I have been waiting 5 [days] to find it, and it wasn’t even fu**ing tested!!!! What a disappointment in your office and the bullsh** I was told. I will be switching plans because this is sh**!”
Researchers also noted some high-frequency words associated with violence, such as “shoot,” “fight,” and “kill.”
“This is concerning, especially given documentation of patient-inflicted violence against physicians. Health systems should be proactive in ensuring that the in-basket does not become a venue for physician abuse and cyberbullying,” the researchers wrote in JAMA Network Open.
“Posting reminders in EHR patient portals to use kind language when sending messages, applying filters for expletives or threatening words, and creating frameworks for identifying patients who frequently send negative messages are potential strategies for mitigating this risk.”
Using a form of artificial intelligence technology called natural language processing (NLP), researchers at the University of California, San Diego, analyzed the characteristics of more than 1.4 million emails received by the university’s physicians, 43% of them from patients. They specifically looked at the volume of messages, word count, and overall sentiment.
Whereas other studies have examined the growing burden of EHR messaging for doctors, this type of email sentiment analysis could help in creating solutions. Researchers say that one such solution could involve applying filters for expletives or threatening words. It also could help identify fixable health system issues that make patients so angry, the researchers say.
Among the emails from physicians to physicians, just over half reported burnout, which correlated to the following phrases: “I am beginning to burn out and have one or more symptoms of burnout” and “I feel completely burned out [and] am at the point where I may need to seek help.”
On average, physicians who reported burnout received a greater volume of patient messages. The odds of burnout were significantly higher among Hispanic/Latinx physicians and females. Physicians with more than 15 years of clinical practice had markedly lower burnout.
Despite physicians now spending more time on EHR in-basket tasks than they did before the pandemic, the study found no significant associations between message characteristics and burnout.
Data for the cross-sectional study were collected from multiple specialties from April to September 2020. Physicians then completed a survey and assessed their burnout on a 5-point scale. Of the 609 physician responses, approximately 49% of participants were women, 56% were White, and 64% worked in outpatient settings. About 70% of the doctors had been in practice for 15 years or less.
The sentiment score was based on word content as well as the use of negation, punctuation, degree modifiers, all caps, emoticons, emojis, and acronyms. Positive patient messages were more likely to convey gratitude and thanks, along with casual expressions, such as “fyi” and “lol.”

Single chest x-ray could predict 10-year CVD risk
who presented the results of their deep-learning model at the annual meeting of the Radiological Society of North America.
Current American College of Cardiologists and American Heart Association guidelines recommend estimating 10-year risk of major adverse cardiovascular events (MACE) to determine whether a patient should receive statins to help prevent atherosclerotic cardiovascular disease (ASCVD). Statins are recommended for patients with a 10-year risk of 7.5% or higher, the authors noted.
The current ASCVD risk score is determined with nine factors: age, sex, race, systolic blood pressure, hypertension treatment, smoking, type 2 diabetes, and a lipid panel.
Not all data points available in EHR
But not all of those data points may be available through the electronic health record, “which makes novel and easier approaches for population-wide screening desirable,” said lead researcher Jakob Weiss, MD, a radiologist affiliated with the Cardiovascular Imaging Research Center at Massachusetts General Hospital and the AI in medicine program at the Brigham and Women’s Hospital in Boston.
Chest x-ray images, on the other hand, are commonly available. The images carry rich information beyond diagnostic data but have not been used in this type of prediction model because AI models have been lacking, Dr. Weiss said.
The researchers trained a deep-learning model with single chest x-rays only.
They used 147,497 chest x-rays from 40,643 participants in the Prostate, Lung, Colorectal, and Ovarian Cancer (PLCO) Screening Trial, a multicenter, randomized controlled trial designed and sponsored by the National Cancer Institute.
Dr. Weiss acknowledged that the population used to train the model was heavily White and that should be a consideration in validating the model.
They compared their model’s ability to predict 10-year ASCVD risk with the standard ACC/AHA model.
“Based on a single chest radiograph image, deep learning can predict the risk of future cardiovascular events independent of cardiovascular risk factors and with similar performance to the established and guideline-recommended ASCVD risk score,” Dr. Weiss said.
Tested against independent group
They tested the model against an independent group of 11,430 outpatients (average age, 60 years; 42.9% male) who underwent a routine outpatient chest x-ray at Mass General Brigham and were potentially eligible to receive statins.
Of those 11,430 patients, 1,096 (9.6%) had a major adverse cardiac event over the median follow-up of 10.3 years.
There was a significant association of CXR-CVD risk and MACE among patients eligible to receive statins, the researchers found (hazard ratio, 2.03; 95% confidence interval, 1.81-2.30; P < .001), which remained significant after adjusting for cardiovascular risk factors (adjusted HR, 1.63; 95% CI, 1.43-1.86; P < .001).
Some of the variables were missing in the standard model, but in a subgroup of 2,401 patients, all the variables were available.
They calculated ASCVD risk in that subgroup using the standard model and the CXR model and found that the performance was similar (c-statistic, 0.64 vs. 0.65; P = .48) to the ASCVD risk score (aHR, 1.58; 95% CI, 1.20-2.09; P = .001).
Ritu R. Gill MD, MPH, associate professor of radiology at Harvard Medical School in Boston, who was not part of the study, said in an interview that “the predictive algorithm is promising and potentially translatable and could enhance the annual medical checkup in a select population.
“The algorithm was developed using the PLCO cohort with radiographs, which are likely subjects in the lung cancer screening arm,” she said. “This cohort would be at high risk of cardiovascular diseases, as smoking is a known risk factor for atherosclerotic disease, and therefore the results are expected.
“The algorithm needs to be validated in an independent database with inclusion of subjects with younger age groups and adjusted for gender and racial diversity,” Gill said.
David Cho, MD, a cardiologist at the University of California, Los Angeles, who also was not part of the study, said in an interview that “this work is a great example of AI being able to detect clinically relevant outcomes with a widely used and low-cost screening test.
“The volume of data needed to train these models is already out there,” Dr. Cho said. “It just needs to be mined.”
He noted that this tool, if validated in randomized trials, could help determine risk among patients living in places where access to specialized cardiac care is limited.
Dr. Weiss and Dr. Cho disclosed no relevant financial relationships. Dr. Gill has received research support from Cannon Inc and consultant fees from Imbio and WorldCare.

Covid vax prevents death in children regardless of variant
The vaccine’s effectiveness against infection in the short term has been established, as has the waning effectiveness of the vaccine over time, wrote Juan Manuel Castelli, MD, of the Ministry of Health of Argentina, Buenos Aires, and colleagues, in the British Medical Journal.
However, data on the impact of vaccine effectiveness on mortality in children and adolescents are limited, especially during periods of omicron variant dominance, the researchers said.
In their new study, the researchers reviewed data from 844,460 children and adolescents aged 3-17 years from the National Surveillance System and the Nominalized Federal Vaccination Registry of Argentina, during a time that included a period of omicron dominance.
Argentina began vaccinating adolescents aged 12-17 years against COVID-19 in August 2021 and added children aged 3-11 years in October 2021. Those aged 12-17 years who were considered fully vaccinated received two doses of either Pfizer-BioNTech and/or Moderna vaccines, and fully-vaccinated 3- to 11-year-olds received two doses of Sinopharm vaccine.
The average time from the second vaccine dose to a COVID-19 test was 66 days for those aged 12-17 years and 54 days for 3- to 11-year-olds. The researchers matched COVID-19 cases with uninfected controls, and a total of 139,321 cases were included in the analysis.
Overall, the estimated vaccine effectiveness against COVID-19 was 64.2% during a period of delta dominance (61.2% in children aged 3-11 years and 66.8% in adolescents aged 12-17 years).
During a period of omicron dominance, estimated vaccine effectiveness was 19.9% across all ages (15.9% and 26.0% for younger and older age groups, respectively).
Effectiveness of the vaccine decreased over time, regardless of the dominant variant, but the decline was greater during the omicron dominant period, the researchers noted. During the omicron period, effectiveness in children aged 3-11 years decreased from 37.6% at 15-30 days postvaccination to 2.0% at 60 days or longer after vaccination. In adolescents aged 12-17 years, vaccine effectiveness during the omicron period decreased from 55.8% at 15-30 days postvaccination to 12.4% at 60 days or longer after vaccination.
Despite the waning protection against infection, the vaccine’s effectiveness against death from COVID-19 was 66.9% in children aged 3-11 years and 97.6% in adolescents aged 12-17 during the period of omicron dominance, the researchers noted.
The results are consistent with similar studies showing a decreased vaccine effectiveness against infection but a persistent effectiveness against deaths over time, the researchers wrote in the discussion section of their paper.
“Our results suggest that the primary vaccination schedule is effective in preventing mortality in children and adolescents with COVID-19 regardless of the circulating SARS-CoV-2 variant,” the researchers said.
Study limitations and strengths
The study was limited by several factors including the incomplete data on symptoms and hospital admissions, the possible impact of unmeasured confounding variables, and the observational design that prevents conclusions of causality, the researchers noted. However, the results were strengthened by the large sample size and access to detailed vaccination records, they said.
Both heterologous and homologous mRNA vaccine schedules showed similar effectiveness in preventing short-term infection and mortality from COVID-19 during periods of differing dominant variants, they noted.
The study findings support the vaccination of children against COVID-19 as an important public health measure to prevent mortality in children and adolescents, they concluded.
Data support value of vaccination, outside experts say
“COVID vaccines may not be as effective over time as the gene variants in the SARS-CoV-2 virus change,” Adrienne G. Randolph, MD, a pediatrician at Harvard Medical School and Boston Children’s Hospital, said in an interview. “Therefore, it is essential to assess vaccine effectiveness over time to look at effectiveness against variants and duration of effectiveness.” Dr. Randolph, who was not involved in the study, said she was not surprised by the findings, which she described as consistent with data from the United States. “COVID vaccines are very effective against preventing life-threatening disease, but the effectiveness against less severe illness for COVID vaccines is not as effective against Omicron,” she noted.
The take-home message for clinicians is that it’s important to get children vaccinated against COVID to prevent severe and life-threatening illness, said Dr. Randolph. “Although these cases are uncommon in children, it is not possible to predict which children will be the most severely affected by COVID,” she emphasized.
However, “we need more data on the new COVID booster vaccines in children that are designed to be more effective against Omicron’s newer variants,” Dr. Randolph said in an interview. “We also need more data on COVID vaccine effectiveness in the youngest children, under 5 years of age, and data on vaccinating mothers to prevent COVID in infants,” she said.
Tim Joos, MD, a Seattle-based clinician who practices a combination of internal medicine and pediatrics, agreed that future research should continue to assess how the new COVID boosters are faring against new variants, noting that the current study did not include data from children who received the new bivalent vaccine.
“The methodology of this study uses a test negative case control design which is common for estimating vaccine effectiveness post-release of a vaccine, but is subject to biases,” Dr. Joos explained. “These are not the clean effectiveness numbers of the prospective randomized control trials that we are used to hearing about when a vaccine is first being approved.”
“Nevertheless, the study reinforces the initial manufacturers’ studies that the vaccines are effective at preventing infection in the pediatric population,” Dr. Joos said in an interview. The current study also reinforces the effectiveness of vaccines in preventing “the rare but devastating mortality from COVID-19 in the pediatric population.”
Commenting on other research showing an increasing ratio of COVID deaths among vaccinated individuals compared to total COVID deaths, he noted that this finding is “likely reflecting a denominator effect of rapidly declining COVID deaths overall,” partly from the vaccines and partly from immunity after previous natural infection.
The study received no outside funding. The researchers, Dr. Randolph, and Dr. Joos had no financial conflicts to disclose. Dr. Joos serves on the Editorial Advisory Board of Pediatric News.
The vaccine’s effectiveness against infection in the short term has been established, as has the waning effectiveness of the vaccine over time, wrote Juan Manuel Castelli, MD, of the Ministry of Health of Argentina, Buenos Aires, and colleagues, in the British Medical Journal.
However, data on the impact of vaccine effectiveness on mortality in children and adolescents are limited, especially during periods of omicron variant dominance, the researchers said.

During a period of omicron dominance, estimated vaccine effectiveness was 19.9% across all ages (15.9% and 26.0% for younger and older age groups, respectively).
Effectiveness of the vaccine decreased over time, regardless of the dominant variant, but the decline was greater during the omicron dominant period, the researchers noted. During the omicron period, effectiveness in children aged 3-11 years decreased from 37.6% at 15-30 days postvaccination to 2.0% at 60 days or longer after vaccination. In adolescents aged 12-17 years, vaccine effectiveness during the omicron period decreased from 55.8% at 15-30 days postvaccination to 12.4% at 60 days or longer after vaccination.
Despite the waning protection against infection, the vaccine’s effectiveness against death from COVID-19 was 66.9% in children aged 3-11 years and 97.6% in adolescents aged 12-17 during the period of omicron dominance, the researchers noted.
The results are consistent with similar studies showing a decreased vaccine effectiveness against infection but a persistent effectiveness against deaths over time, the researchers wrote in the discussion section of their paper.
“Our results suggest that the primary vaccination schedule is effective in preventing mortality in children and adolescents with COVID-19 regardless of the circulating SARS-CoV-2 variant,” the researchers said.
Study limitations and strengths
The study was limited by several factors including the incomplete data on symptoms and hospital admissions, the possible impact of unmeasured confounding variables, and the observational design that prevents conclusions of causality, the researchers noted. However, the results were strengthened by the large sample size and access to detailed vaccination records, they said.
Both heterologous and homologous mRNA vaccine schedules showed similar effectiveness in preventing short-term infection and mortality from COVID-19 during periods of differing dominant variants, they noted.
The study findings support the vaccination of children against COVID-19 as an important public health measure to prevent mortality in children and adolescents, they concluded.
Data support value of vaccination, outside experts say
“COVID vaccines may not be as effective over time as the gene variants in the SARS-CoV-2 virus change,” Adrienne G. Randolph, MD, a pediatrician at Harvard Medical School and Boston Children’s Hospital, said in an interview. “Therefore, it is essential to assess vaccine effectiveness over time to look at effectiveness against variants and duration of effectiveness.” Dr. Randolph, who was not involved in the study, said she was not surprised by the findings, which she described as consistent with data from the United States. “COVID vaccines are very effective against preventing life-threatening disease, but the effectiveness against less severe illness for COVID vaccines is not as effective against Omicron,” she noted.
The take-home message for clinicians is that it’s important to get children vaccinated against COVID to prevent severe and life-threatening illness, said Dr. Randolph. “Although these cases are uncommon in children, it is not possible to predict which children will be the most severely affected by COVID,” she emphasized.
However, “we need more data on the new COVID booster vaccines in children that are designed to be more effective against Omicron’s newer variants,” Dr. Randolph said in an interview. “We also need more data on COVID vaccine effectiveness in the youngest children, under 5 years of age, and data on vaccinating mothers to prevent COVID in infants,” she said.
Tim Joos, MD, a Seattle-based clinician who practices a combination of internal medicine and pediatrics, agreed that future research should continue to assess how the new COVID boosters are faring against new variants, noting that the current study did not include data from children who received the new bivalent vaccine.
“The methodology of this study uses a test negative case control design which is common for estimating vaccine effectiveness post-release of a vaccine, but is subject to biases,” Dr. Joos explained. “These are not the clean effectiveness numbers of the prospective randomized control trials that we are used to hearing about when a vaccine is first being approved.”
“Nevertheless, the study reinforces the initial manufacturers’ studies that the vaccines are effective at preventing infection in the pediatric population,” Dr. Joos said in an interview. The current study also reinforces the effectiveness of vaccines in preventing “the rare but devastating mortality from COVID-19 in the pediatric population.”
Commenting on other research showing an increasing ratio of COVID deaths among vaccinated individuals compared to total COVID deaths, he noted that this finding is “likely reflecting a denominator effect of rapidly declining COVID deaths overall,” partly from the vaccines and partly from immunity after previous natural infection.
The study received no outside funding. The researchers, Dr. Randolph, and Dr. Joos had no financial conflicts to disclose. Dr. Joos serves on the Editorial Advisory Board of Pediatric News.
The vaccine’s effectiveness against infection in the short term has been established, as has the waning effectiveness of the vaccine over time, wrote Juan Manuel Castelli, MD, of the Ministry of Health of Argentina, Buenos Aires, and colleagues, in the British Medical Journal.
However, data on the impact of vaccine effectiveness on mortality in children and adolescents are limited, especially during periods of omicron variant dominance, the researchers said.
In their new study, the researchers reviewed data from 844,460 children and adolescents aged 3-17 years from the National Surveillance System and the Nominalized Federal Vaccination Registry of Argentina, during a time that included a period of omicron dominance.
Argentina began vaccinating adolescents aged 12-17 years against COVID-19 in August 2021 and added children aged 3-11 years in October 2021. Those aged 12-17 years who were considered fully vaccinated received two doses of either Pfizer-BioNTech and/or Moderna vaccines, and fully-vaccinated 3- to 11-year-olds received two doses of Sinopharm vaccine.
The average time from the second vaccine dose to a COVID-19 test was 66 days for those aged 12-17 years and 54 days for 3- to 11-year-olds. The researchers matched COVID-19 cases with uninfected controls, and a total of 139,321 cases were included in the analysis.
Overall, the estimated vaccine effectiveness against COVID-19 was 64.2% during a period of delta dominance (61.2% in children aged 3-11 years and 66.8% in adolescents aged 12-17 years).
During a period of omicron dominance, estimated vaccine effectiveness was 19.9% across all ages (15.9% and 26.0% for younger and older age groups, respectively).
Effectiveness of the vaccine decreased over time, regardless of the dominant variant, but the decline was greater during the omicron dominant period, the researchers noted. During the omicron period, effectiveness in children aged 3-11 years decreased from 37.6% at 15-30 days postvaccination to 2.0% at 60 days or longer after vaccination. In adolescents aged 12-17 years, vaccine effectiveness during the omicron period decreased from 55.8% at 15-30 days postvaccination to 12.4% at 60 days or longer after vaccination.

Higher potency of fentanyl affects addiction treatment, screening
As fentanyl-related overdose deaths continue to increase, clinicians should take note of important differences that set the drug apart from the other drugs of misuse – and the troubling reality that fentanyl now contaminates most of them.
“It would be fair to tell patients, if you’re buying any illicit drugs – pills, powder, liquid, whatever it is, you’ve got to assume it’s either contaminated with or replaced by fentanyl,” said Edwin Salsitz, MD, an associate clinical professor at the Icahn School of Medicine at Mount Sinai, New York, during a presentation on the subject at the 21st Annual Psychopharmacology Update presented by Current Psychiatry and the American Academy of Clinical Psychiatrists.
In many if not most cases, he noted, patients become addicted to fentanyl unknowingly. They assume they are ingesting oxycodone, cocaine, or another drug, and have no realization that they are even exposed to fentanyl until they test positive for it – or overdose.
Meanwhile, the high potency of fentanyl can overcome the opioid blockade of addiction treatment therapies – methadone and buprenorphine – that take away the high that users get from less potent drugs such as heroin.
“Fentanyl is overcoming this blockade that methadone and buprenorphine used to provide,” Dr. Salsitz said. “With fentanyl having such a higher potency, patients are saying ‘no, I still feel the fentanyl effects,’ and they continue feeling it even with 200 milligrams of methadone or 24 milligrams of buprenorphine.”
‘Wooden chest syndrome’
Among the lesser-known dangers of fentanyl is the possibility that some overdose deaths may occur as the result of a syndrome previously reported as a rare complication following the medical use of fentanyl in critically ill patients – fentanyl-induced chest-wall rigidity, or “wooden chest syndrome,” Dr. Salsitz explained.
In such cases, the muscles of respiration become rigid and paralyzed, causing suffocation within a matter of minutes – too soon to benefit from the overdose rescue medication naloxone.
In one recent study published in Clinical Toxicology , nearly half of fentanyl overdose deaths were found to have occurred even before the body had a chance to produce norfentanyl, a metabolite of fentanyl that takes only about 2-3 minutes to appear in the system, suggesting the deaths occurred rapidly.
In the study of 48 fentanyl deaths, no appreciable concentrations of norfentanyl could be detected in 20 of the 48 overdose deaths (42%), and concentrations were less than 1 ng/mL in 25 cases (52%).
“The lack of any measurable norfentanyl in half of our cases suggests a very rapid death, consistent with acute chest rigidity,” the authors reported.
“In several cases fentanyl concentrations were strikingly high (22 ng/mL and 20 ng/mL) with no norfentanyl detected,” they said.
Dr. Salsitz noted that the syndrome is not well known among the addiction treatment community.
“This is different than the usual respiratory opioid overdose where there’s a gradual decrease in the breathing rate and a gradual decrease in how much air is going in and out of the lungs,” Dr. Salsitz explained.
“With those cases, some may survive for an hour or longer, allowing time for someone to administer naloxone or to get the patient to the emergency room,” he said. “But with this, breathing stops and people can die within minutes.
“I think that this is one of the reasons that fentanyl deaths keep going up despite more and more naloxone availability out there,” he said.
Clearance may take longer
In toxicology testing for fentanyl, clinicians should also note the important difference between fentanyl and other opioids – that fentanyl, because of its high lipophilicity, may be detected in urine toxicology testing up to 3 weeks after last use. This is much longer than the 2- to 4-day clearance observed with other opioids, possibly causing patients to continue to test positive for the drug weeks after cessation.
This effect was observed in one recent study of 12 opioid use disorder patients in a residential treatment program who had previously been exposed to daily fentanyl.
The study showed the mean amount of time of fentanyl clearance was 2 weeks, with a range of 4-26 days after last use.
The authors pointed out that the findings “might explain recent reports of difficulty in buprenorphine inductions for persons who use fentanyl, and point to a need to better understand the pharmacokinetics of fentanyl in the context of opioid withdrawal in persons who regularly use fentanyl.”
Though the study was small, Dr. Salsitz said “that’s not a stumbling block to the important finding that, with regular use of fentanyl, the drug may stay in the urine for a long time.”
Dr. Salsitz noted that similar observations have been made at his center, with clinicians logically assuming that patients were still somehow getting fentanyl.
“When we initially found this in patients, we thought that they were using on the unit, perhaps that they brought in the fentanyl, because otherwise how could it stay in the urine that long,” he noted. “But fentanyl appears to be more lipophilic and gets into the fat; it’s then excreted very slowly and then stays in the urine.”
Dr. Salsitz said most practitioners think of fentanyl as a short-acting drug, so “it’s important to realize that people may continue to test positive and it should be thought of as a long-acting opioid.”
Opiate screening tests don’t work
Dr. Salsitz warned of another misconception in fentanyl testing – the common mistake of assuming that fentanyl should show up in a test for opiates – when in fact fentanyl is not, technically, an opiate.
“The word opiate only refers to morphine, codeine, heroin and sometimes hydrocodone,” he explained. “Other opioids are classified as semisynthetic, such as oxycodone, or synthetics, such as fentanyl and methadone, buprenorphine.”
“In order to detect the synthetics, you must have a separate strip for each one of those drugs. They will not show up positive on a screen for opiates,” he noted.
The belief that fentanyl and other synthetic and semisynthetic opioids will show positive on an opiate screen is a common misconception, he said. “The misunderstanding in toxicology interpretation is a problem for many practitioners, [but] it’s essential to understand because otherwise false assumptions about the patient will be considered.”
Another important testing misreading can occur with the antidepressant drug trazodone, which Dr. Salsitz cautioned may falsely test as positive for fentanyl on immunoassays.
“Trazodone is very commonly used in addiction treatment centers, but it can give a false positive on the fentanyl immunoassay and we’ve had a number of those cases,” he said.

Looking for a healthy meat substitute? Consider the potato
Boil ‘em, mash ‘em, include ‘em in a balanced diet
It’s kind of funny that, even though potatoes are vegetables and vegetables are generally considered to be healthy foods, not many people think of potatoes as being particularly good for you. And that’s hardly surprising since we usually either consume them in the form of French fries or potato chips, neither of which are known for their healthiness.
In fact, some previous research shows that potatoes are a food to avoid, particularly for people with insulin resistance. However, a new study from England goes against the grain and asserts that the potato is perfectly fine for insulin-resistant individuals and filled with valuable nutrients and health benefits. Which is great news for the state of Idaho and the potato organization funding the research. Of course there’s a potato organization.
For the study, a group of obese, overweight, or insulin-resistant individuals received a diet of either beans, peas, and meat or fish or white potatoes with meat or fish for 8 weeks; both diets were heavy in fruits and vegetables and both diets replaced about 40% of typical meat consumption with either beans and peas or potatoes. By the end of the study, those on the potato diet experienced health benefits equivalent to those on the bean and pea diet, including losing roughly equivalent amounts of weight and similarly reducing the body’s insulin response.
The researchers noted that, because people tend to eat the same amount of food no matter what, replacing something like meat with dense, low-calorie potatoes meant study participants could eat normally yet consume much fewer calories. So you could make a delicious, healthy stew without the brace of conies and the nice fish, which would make Smeagol very happy.
You won’t have ‘monkeypox’ to kick around anymore
It’s true. No more monkeypox. It’s gone. It’s history. Adios. The World Health Organization said that the disease formerly known as monkeypox will now be called mpox. What? You didn’t think it had been cured, did you? You did? Really? Silly readers.
“Mpox will become a preferred term, replacing monkeypox, after a transition period of 1 year. This serves to mitigate the concerns raised by experts about confusion caused by a name change in the midst of a global outbreak,” WHO said in a statement announcing the change.
The stigma attached to the name was the main problem. New York City Health Commissioner Dr. Ashwin Vasan had sent a letter to WHO earlier this year, according to CNN, saying that there was “growing concern for the potentially devastating and stigmatizing effects that the messaging around the ‘monkeypox’ virus can have on … vulnerable communities.”
We here at LOTME applaud the fight against stigmas of any sort, but we sensed there was more to this name change business, so our dedicated team of investigative journalists went into action. Sure enough, while rooting through WHO Director-General Tedros Adhanom Ghebreyesus’s garbage, we found a list of the names that had been rejected in favor of mpox:
- K-pop (already taken)
- Keeping up with the Kardashi-pox
- Trumpox
- Pox the magic dragon
- Monkey plague (didn’t really solve the problem)
- Hockey pox
- Mission mpoxible
- Jurassic Pox
- The pox that refreshes
- Debbie
Feet catch what the ears miss
The spectrum of frequencies that can be heard by human ears varies from person to person. Then there’s the matter of personal taste in music and volume level. But what really gets people moving? A new study shows that it’s more about the frequency of the sound than the volume.
For the study, participants at a concert by electronic music duo Orphx at LIVELab – a research performance center on the McMaster University campus in Hamilton, Ont., that was specifically designed to study music and dance – filled out questionnaires before and after the show. They also wore motion-capture headbands to detect their movement throughout the concert. During the show the researchers turned very-low-frequency (VLF) sounds (8-37 Hz) on and off every 2.5 minutes. Movement speed was calculated during on and off periods.
Although the effects of subliminal messaging aren’t new, past studies have shown that participants were mostly aware of the messaging. In this study, the researchers found that the subjects’ movements increased by 11.8% when the VLF sounds were on, but without their awareness. The researchers and the participants attributed movement to the bass, as lower pitches tend to elicit stronger neural responses and thus movement, compared with higher pitches.
“Our whole sense of the beat is mediated by the vestibular system but nobody’s really, I think, effectively confirmed that,” Jonathan Cannon, an assistant professor of psychology, neuroscience, and behavior at McMaster who not involved in the study, told Live Science.
Not to say this study didn’t have its limitations, such as the effect of the surrounding crowd or vibrations of the floor influencing the need to dance. But it definitely makes you wonder about what’s actually playing in your favorite song.
Uncle Leonid wants you
Do you like to travel? Are you a bit of a thrill seeker? Do you have any extra socks? If you’re a physician who answered yes to those three questions, then we’ve got an opportunity for you.
Leonid Slutsky, leader of Russia’s populist Liberal Democratic Party and chairman of the foreign relations committee in the lower house of Russia’s parliament – yes, that Leonid Slutsky – recently made a bit of a recruiting pitch, although that’s not how ABC News described it.
Mr. Slutsky, a strong supporter of his country’s war against Ukraine, recently told the mothers of Russian soldiers “that the whole world is watching us. We are the largest state and when we do not have socks, shorts, doctors, intelligence, communications, or simply care for our children, questions arise that will be very difficult to answer.”
It’s probably not what he meant, but the lack of intelligence is pretty clear.
Boil ‘em, mash ‘em, include ‘em in a balanced diet
It’s kind of funny that, even though potatoes are vegetables and vegetables are generally considered to be healthy foods, not many people think of potatoes as being particularly good for you. And that’s hardly surprising since we usually either consume them in the form of French fries or potato chips, neither of which are known for their healthiness.
In fact, some previous research shows that potatoes are a food to avoid, particularly for people with insulin resistance. However, a new study from England goes against the grain and asserts that the potato is perfectly fine for insulin-resistant individuals and filled with valuable nutrients and health benefits. Which is great news for the state of Idaho and the potato organization funding the research. Of course there’s a potato organization.
For the study, a group of obese, overweight, or insulin-resistant individuals received a diet of either beans, peas, and meat or fish or white potatoes with meat or fish for 8 weeks; both diets were heavy in fruits and vegetables and both diets replaced about 40% of typical meat consumption with either beans and peas or potatoes. By the end of the study, those on the potato diet experienced health benefits equivalent to those on the bean and pea diet, including losing roughly equivalent amounts of weight and similarly reducing the body’s insulin response.
The researchers noted that, because people tend to eat the same amount of food no matter what, replacing something like meat with dense, low-calorie potatoes meant study participants could eat normally yet consume much fewer calories. So you could make a delicious, healthy stew without the brace of conies and the nice fish, which would make Smeagol very happy.
You won’t have ‘monkeypox’ to kick around anymore
It’s true. No more monkeypox. It’s gone. It’s history. Adios. The World Health Organization said that the disease formerly known as monkeypox will now be called mpox. What? You didn’t think it had been cured, did you? You did? Really? Silly readers.
“Mpox will become a preferred term, replacing monkeypox, after a transition period of 1 year. This serves to mitigate the concerns raised by experts about confusion caused by a name change in the midst of a global outbreak,” WHO said in a statement announcing the change.
The stigma attached to the name was the main problem. New York City Health Commissioner Dr. Ashwin Vasan had sent a letter to WHO earlier this year, according to CNN, saying that there was “growing concern for the potentially devastating and stigmatizing effects that the messaging around the ‘monkeypox’ virus can have on … vulnerable communities.”
We here at LOTME applaud the fight against stigmas of any sort, but we sensed there was more to this name change business, so our dedicated team of investigative journalists went into action. Sure enough, while rooting through WHO Director-General Tedros Adhanom Ghebreyesus’s garbage, we found a list of the names that had been rejected in favor of mpox:
- K-pop (already taken)
- Keeping up with the Kardashi-pox
- Trumpox
- Pox the magic dragon
- Monkey plague (didn’t really solve the problem)
- Hockey pox
- Mission mpoxible
- Jurassic Pox
- The pox that refreshes
- Debbie
Feet catch what the ears miss
The spectrum of frequencies that can be heard by human ears varies from person to person. Then there’s the matter of personal taste in music and volume level. But what really gets people moving? A new study shows that it’s more about the frequency of the sound than the volume.
For the study, participants at a concert by electronic music duo Orphx at LIVELab – a research performance center on the McMaster University campus in Hamilton, Ont., that was specifically designed to study music and dance – filled out questionnaires before and after the show. They also wore motion-capture headbands to detect their movement throughout the concert. During the show the researchers turned very-low-frequency (VLF) sounds (8-37 Hz) on and off every 2.5 minutes. Movement speed was calculated during on and off periods.
Although the effects of subliminal messaging aren’t new, past studies have shown that participants were mostly aware of the messaging. In this study, the researchers found that the subjects’ movements increased by 11.8% when the VLF sounds were on, but without their awareness. The researchers and the participants attributed movement to the bass, as lower pitches tend to elicit stronger neural responses and thus movement, compared with higher pitches.

Newer agents for nosocomial pneumonia: The right drug for the right bug
“The right drug at the right time with the right dose for the right bug for the right duration.” That, said professor Kristina Crothers, MD, is the general guidance for optimizing antibiotic use (while awaiting an infectious disease consult). In her oral presentation at the annual meeting of the American College of Chest Physicians, “Choosing newer antibiotics for nosocomial pneumonia,” Dr. Crothers asked the question: “Beyond the guidelines: When should novel antimicrobials be used?”
Hospital-acquired pneumonia (HAP) and ventilator-associated pneumonia (VAP) are the most common nosocomial infections at 22%, and are the leading cause of death attributable to hospital-acquired infections. They increase mortality by 20%-50%, with an economic burden of about $40,000 per patient. The incidence of multidrug-resistant (MDR) organism infections varies widely by locality, but several factors increase the likelihood: prior broad-spectrum antibiotic exposure within the past 90 days; longer hospitalization; indwelling vascular devices; tracheostomy; and ventilator dependence. The Centers for Disease Control and Prevention lists as “Serious Threat” the HAP/VAP MDR organisms methicillin resistant Staphylococcus aureus (MRSA), Pseudomonas aeruginosa (PSA) with difficult-to-treat-resistance, and beta-lactamase producing Enterobacterales (ESBL). In the category of “Urgent Threat” the CDC lists: carbapenamase-resistant Enterobacterales (CRE) (carbapenamase producing or non–carbapenemase producing), and carbapenem-resistant Acinetobacter (CRAB), according to Dr. Crothers who is at the University of Washington Veterans Affairs Puget Sound Health Care System, Seattle.
Newer antibiotics for HAP/VAP that are still beyond the guidelines include telavancin and tedizolid as gram-positive agents, and as gram-negative ones: ceftazidime-avibactam, ceftolozane-tazobactam, cefiderocol, imipenem-cilastatin-relebactam and meropenem-vaborbactam, she added.
Tedizolid, Dr. Crothers stated, is a novel oxazolidinone, and is an alternative to vancomycin and linezolid for gram-positive HAP/VAP. In the VITAL noninferiority study versus linezolid with 726 patients, it was noninferior to linezolid for 28-day all-cause mortality (28% vs. 26%), but did not achieve noninferiority for investigator-assessed clinical cure (56% vs. 64%).
Televancin, a semisynthetic derivative of vancomycin, in the ATTAIN studies vs. vancomycin had overall similar cure rates. It is FDA-approved for S. aureus HAP/VAP but not other bacterial causes. It should be reserved for those who cannot receive vancomycin or linezolid, with normal renal function, according to Dr. Crothers. Excluded from first-line treatment of gram-positive HAP/VAP are daptomycin, ceftaroline, ceftobiprole, and tigecycline.
Ceftazidime-avibactam, a third-generation cephalosporin-plus novel beta-lactamase inhibitor has wide activity (Klebsiella pneumoniae, Enterobacter cloacae, Escherichia coli, Serratia marcescens, Proteus mirabilis, PSA and Haemophilus influenzae. It is also active against some extended-spectrum beta-lactamases (ESBLs), ampC beta-lactamases (AmpCs), and K. pneumoniae carbapenemase (KPC)–producing Enterobacterales, but not with metallo-beta-lactamases). Ceftazidime-avibactam is also indicated for HAP/VAP, and has a toxicity profile including nausea, vomiting, and diarrhea.
In the REPROVE trial of ceftazidime-avibactam vs. meropenem for 7-14 days with 527 clinically evaluable patients (37% K. pneumoniae, 30% P. aeruginosa, and 33%-35% VAP), the clinical cure at 21-25 days post randomization was 69% vs. 73%, respectively, with similar adverse events.
Ceftolozane-tazobactam, a novel fifth-generation cephalosporin plus a beta-lactamase inhibitor has activity against PSA including extensively drug-resistant PSA, AmpC, and ESBL-E, but it has limited activity against Acinetobacter and Stenotrophomonas. It is indicated for HAP/VAP, has reduced efficacy with creatine clearance of 50 mL/min or less, increases transaminases and renal impairment, and causes diarrhea. In ASPECT-NP (n = 726) ceftolozane-tazobactam versus meropenem for 8-14 days (HAP/VAP), showed a 28 day-mortality of 24% vs. 25%, respectively, with test of cure at 54% vs. 53% at 7-14 days post therapy. Adverse events were similar between groups.
Imipenem-cilastatin-relebactam, a novel beta-lactamase inhibitor plus carbapenem, is indicated for HAP/VAP and has activity against ESBL, CRE: KPC-producing Enterobacterales, PSA including AmpC. It can cause seizures (requires caution with central nervous system disorders and renal impairment). It increases transaminases, anemia, diarrhea, and reduces potassium and sodium. In RESTORE-IMI 2 (n = 537 with HAP/VAP) it was noninferior for 28-day all-cause mortality vs. piperacillin and tazobactam (16% vs. 21%), with similar adverse events.
Cefiderocol, a siderophore cephalosporin, is indicated for HAP/VAP. It has a wide spectrum of activity: ESBL, CRE, CR PSA, Stenotrophomonas maltophilia, Acinetobacter baumanii, Streptococcus.) It increases transaminases, diarrhea, and atrial fibrillation, and it reduces potassium and magnesium. In APEKS-NP versus linezolid plus cefiderocol or extended meropenem infusion (HAP/VAP n = 292; gram-negative pneumonia = 251; 60% invasive mechanical ventilation) it was noninferior for 14-day all-cause mortality (12.4% vs. 11.6%) with similar adverse events. In CREDIBLE-CR vs. best available therapy for carbapenem-resistant gram-negative infections, clinical cure rates were similar (50% vs. 53% in 59 HAP/VAP patients at 7 days), but with more deaths in the cefiderocol arm. Adverse events were > 90% in both groups and 34% vs. 19% died, mostly with Acinetobacter.
Meropenem-vaborbactam, a novel beta-lactamase inhibitor plus carbapenem, is approved and indicated for HAP/VAP in Europe. It has activity against MDR, Enterobacterales including CRE. Its toxicities include headache, phlebitis/infusion-site reactions and diarrhea. In TANGO-2 versus best available treatment for carbapenem-resistant Enterobacteriaceae (CRE) (n = 77, 47 with confirmed CRE), clinical cure was increased and mortality decreased compared with best available therapy. Treatment- and renal-related adverse events were lower for meropenem-vaborbactam.
In closing, Dr. Crothers cited advice from the paper by Tamma et al. (“Rethinking how Antibiotics are Prescribed” JAMA. 2018) about the need to review findings after therapy has been initiated to confirm the pneumonia diagnosis: Novel agents should be kept in reserve in the absence of MDR risk factors for MRSA and gram-negative bacilli; therapy should be deescalated after 48-72 hours if MDR organisms are not detected; and therapy should be directed to the specific organism detected. Most HAP and VAP in adults can be treated for 7 days, she added.
“Know indications for new therapeutic agents approved for nosocomial pneumonia,” she concluded.
Dr. Crothers reported having no disclosures.

In APEKS-NP versus linezolid plus cefiderocol or extended meropenem infusion (HAP/VAP n = 292; gram-negative pneumonia = 251; 60% invasive mechanical ventilation) it was noninferior for 14-day all-cause mortality (12.4% vs. 11.6%) with similar adverse events. In CREDIBLE-CR vs. best available therapy for carbapenem-resistant gram-negative infections, clinical cure rates were similar (50% vs. 53% in 59 HAP/VAP patients at 7 days), but with more deaths in the cefiderocol arm. Adverse events were > 90% in both groups and 34% vs. 19% died, mostly with Acinetobacter.
Meropenem-vaborbactam, a novel beta-lactamase inhibitor plus carbapenem, is approved and indicated for HAP/VAP in Europe. It has activity against MDR, Enterobacterales including CRE. Its toxicities include headache, phlebitis/infusion-site reactions and diarrhea. In TANGO-2 versus best available treatment for carbapenem-resistant Enterobacteriaceae (CRE) (n = 77, 47 with confirmed CRE), clinical cure was increased and mortality decreased compared with best available therapy. Treatment- and renal-related adverse events were lower for meropenem-vaborbactam.
In closing, Dr. Crothers cited advice from the paper by Tamma et al. (“Rethinking how Antibiotics are Prescribed” JAMA. 2018) about the need to review findings after therapy has been initiated to confirm the pneumonia diagnosis: Novel agents should be kept in reserve in the absence of MDR risk factors for MRSA and gram-negative bacilli; therapy should be deescalated after 48-72 hours if MDR organisms are not detected; and therapy should be directed to the specific organism detected. Most HAP and VAP in adults can be treated for 7 days, she added.
“Know indications for new therapeutic agents approved for nosocomial pneumonia,” she concluded.
Dr. Crothers reported having no disclosures.

U.S. flu activity already at mid-season levels
according to the Centers of Disease Control and Prevention.
Nationally, 6% of all outpatient visits were because of flu or flu-like illness for the week of Nov. 13-19, up from 5.8% the previous week, the CDC’s Influenza Division said in its weekly FluView report.
Those figures are the highest recorded in November since 2009, but the peak of the 2009-10 flu season occurred even earlier – the week of Oct. 18-24 – and the rate of flu-like illness had already dropped to just over 4.0% by Nov. 15-21 that year and continued to drop thereafter.
Although COVID-19 and respiratory syncytial virus (RSV) are included in the data from the CDC’s Outpatient Influenza-like Illness Surveillance Network, the agency did note that “seasonal influenza activity is elevated across the country” and estimated that “there have been at least 6.2 million illnesses, 53,000 hospitalizations, and 2,900 deaths from flu” during the 2022-23 season.
Total flu deaths include 11 reported in children as of Nov. 19, and children ages 0-4 had a higher proportion of visits for flu like-illness than other age groups.
The agency also said the cumulative hospitalization rate of 11.3 per 100,000 population “is higher than the rate observed in [the corresponding week of] every previous season since 2010-2011.” Adults 65 years and older have the highest cumulative rate, 25.9 per 100,000, for this year, compared with 20.7 for children 0-4; 11.1 for adults 50-64; 10.3 for children 5-17; and 5.6 for adults 18-49 years old, the CDC said.

Your patients are rotting their teeth with vaping
Primary care physicians, and especially pediatricians, should consider telling their patients about the long-term oral health problems associated with vaping.
A new study found that patients who use vapes were at a higher risk of developing tooth decay and periodontal disease.
Vapes were introduced to the U.S. market in 2006 as an alternative to conventional cigarettes and have become widely popular among youth. According to a 2022 survey from the U.S. Centers for Disease Control and Prevention, 2.55 million middle and high school students in this country reported using the devices in the previous 30 days.
The new study, published in the Journal of the American Dental Association, expands on an initial case series published in 2020 of patients who reported use of vapes and who had severe dental decay. Karina Irusa, BDS, assistant professor of comprehensive care at Tufts University, Boston, and lead author of the case series, wanted to investigate whether her initial findings would apply to a large population of vape users.
For the new study, Dr. Irusa and colleagues collected data on 13,216 patients aged 16-40 who attended Tufts dental clinics between 2019 and 2021. All patients had received a diagnosis of tooth decay, had a tooth decay risk assessment on record, and had answered “yes” or “no” to use of vapes in a health history questionnaire.
Patients had records on file of varying types of dental lesions, cavities filled within the previous 3 years, heavy plaque on teeth, inadequate brushing and flushing, and a self-report of recreational drug use and frequent snacking. If patients had these factors on their file, they were at high risk of developing decay that leads to cavities.
The study found that 79% of patients who responded “yes” to being a current user of vapes were at high risk for dental decay, compared with 60% of those who did not report using the devices.
Materials in the vaping liquids further cause an inflammatory response that disrupts an individual’s internal microbiome, according to numerous studies.
“All the ingredients of vaping are surely a recipe for overgrowth of cavities causing bacteria,” said Jennifer Genuardi, MD, an internist and pediatrician at federally qualified community health center Urban Health Plan, in New York, who was not involved in the study.
Dr. Irusa said information on patient’s vaping habits should be included in routine dental and medical history questionnaires as part of their overall electronic health record.
“Decay in its severe form not only affects one’s ability to eat but affects facial aesthetics and self-esteem as well,” Dr. Irusa said.
Dr. Genuardi called the findings unsurprising.
“We are learning daily more and more about the dangers of vaping,” Dr. Genuardi said. “There’s a focus of today’s research on the effect of actions on our microbiome and the subsequent effects on our health.”
Dr. Genuardi also said many of her teenage patients do not enjoy dental visits or having cavities filled, which could serve as a useful deterrent to vaping for a demographic that has been targeted with marketing from vape manufacturers.
“Cavity formation and the experience of having cavities filled is an experience teens can identify with, so this to me seems like perhaps an even more effective angle to try to curb this unhealthy behavior of vaping,” Dr. Genuardi said.
The authors have reported no relevant financial relationships.

Rates of health care use after bariatric surgery in teens
Researchers found significantly lower rates of both emergency department (ED) use and hospitalization 5 years after sleeve gastrectomy compared with gastric bypass, and similarly low rates of adverse events.
The study, by researchers with the department of surgery and Center for Health Outcomes and Policy, University of Michigan, Ann Arbor, was published in JAMA.
Studies have shown that sleeve gastrectomy and gastric bypass both lead to significant weight loss and are associated with low complication rates among adolescents with severe obesity.
Until now, however, comparative outcomes for these two weight-loss procedures have not been described for adolescents insured by Medicaid, the largest insurer of adolescents in the United States.
Using Medicaid claims data, Ryan Howard, MD, and colleagues identified 855 adolescents who underwent sleeve gastrectomy and 277 who underwent Roux-en-Y gastric bypass between 2012 and 2018.
Adolescents in both groups were about 18 years old on average at the time of surgery, and about three-quarters were female.
Sleeve gastrectomy became more common over the study period. The annual percentage of sleeve gastrectomy relative to gastric bypass increased from 48.8% in 2012 to 82.6% in 2018.
There was no significant difference in rates of complications (P = .31) or reoperation (P = .78), defined as abdominal operation potentially related to the index procedure, including biliary procedures and abdominal wall, internal, and paraesophageal hernia repair.
Researchers also found no difference between sleeve gastrectomy and gastric bypass in rates of death (P = .42) or revision (P = .63), which included any operation that directly modified the index procedure.
The results “may help inform the treatment of severe obesity in adolescents insured by Medicaid, although future studies should also evaluate long-term weight loss and comorbidity resolution in this population,” Dr. Howard and colleagues write.
They caution that their analysis is subject to selection bias because patient characteristics may influence the choice of procedure, although appropriate statistical adjustment was used.
Other limitations include the small sample size, which increases the possibility of type II error; the relatively short follow-up period; and the inability to directly attribute outcomes to the index procedure.
Funding for the study was provided by a grant from the National Institute of Diabetes and Digestive and Kidney Diseases. The authors have disclosed no relevant financial relationships.

Is it long COVID, or dementia, or both?
In early September, about a week after recovering from COVID-19, Barri Sanders went to the bank to pay a bill. But by mistake, she transferred a large amount of money from the wrong account.
“I’m talking about $20,000,” she said. “I had to go back [later] and fix it.”
Ms. Sanders, 83, had not had confusion like that before. Suddenly, the Albuquerque, N.M., resident found herself looking up from a book and not remembering what she had just read. She would stand up from her chair and forget what she meant to do.
“I kind of thought it was just the aging process,” she said. Combined with sudden balance issues, insomnia, and a nagging postnasal drip, the overall effect was “subtle, but scary,” she said.
After 5 days of this, she went to bed and slept the whole night through. She woke up in the morning to find her balanced restored, her sinuses clear, and the mental fog gone. What she’d had, she realized, wasn’t a rapid start of dementia, but rather a mercifully short form of long COVID.
Somewhere between 22% and 32% of people who recover from COVID-19 get “brain fog,” a nonscientific term used to describe slow or sluggish thinking. While this is disturbing at any age, And some scientists are starting to confirm what doctors, patients, and their families can already see: Older patients who have had COVID-19 have a higher risk of getting dementia or, if they already have mental confusion, the illness may worsen their condition.
British scientists who studied medical records from around the world reported in the journal The Lancet Psychiatry that people who recovered from COVID-19 had a higher risk of problems with their thinking and dementia even after 2 years had passed.
Another 2022 study, published in JAMA Neurology, looked at older COVID-19 patients for a year after they were discharged from hospitals in Wuhan, China. Compared with uninfected people, those who survived a severe case of COVID-19 were at higher risk for early onset, late-onset, and progressive decline in their thinking skills. Those who survived a mild infection were at a higher risk for early onset decline, the study found.
Eran Metzger, MD, assistant professor of psychiatry at Beth Israel Deaconess Medical Center in Boston, said he’s noticed that COVID-19 makes some older patients confused, and their brains don’t regain their former clarity.
“We see a stepwise decline in their cognition during the COVID episode, and then they never get back up to their baseline,” said Dr. Metzger, medical director at Hebrew SeniorLife.
New research is beginning to back up such findings.
People who got COVID-19 were twice as likely to receive a diagnosis of Alzheimer’s disease in the 12 months after infection, compared to those who didn’t get COVID, according to a study published in the journal Nature Medicine , which analyzed the health care databases of the U.S. Department of Veterans Affairs.
Joshua Cahan, MD, a cognitive neurologist at Northwestern University, Chicago, advises caution about applying such a specific label simply from a patient’s medical chart. After all, he noted, few patients get tested to confirm that they have the proteins linked to Alzheimer’s.
“Probably the most appropriate conclusion from that is that there’s an increased risk of dementia after a COVID infection,” he said, “but we don’t know whether it’s truly Alzheimer’s disease or not.”
There could be a number of reasons why COVID-19 triggers a decline in thinking skills, says Michelle Monje, MD, a neuroscientist and neuro-oncologist at Stanford (Calif.) University.
In a paper published in the journal Neuron, Dr. Monje and her coauthor, Akiko Iwasaki, PhD, professor of immunobiology at Yale University, New Haven, Conn., propose possible triggers for brain fog caused by COVID: inflammation in the lungs and respiratory passages that leads to inflammation and dysregulation of the central nervous system; autoimmune reactions that damage the central nervous system; brain infection directly caused by the coronavirus (though, they note, this appears rare); a reactivation of an Epstein-Barr virus, which can lead to neuroinflammation; triggered by the coronavirus; and/or complications from severe cases of COVID-19, possibly involving periods of low blood oxygen and multi-organ failure.
Scientific understanding of brain fog is “part of an emerging picture that inflammation elsewhere in the body can be transmitted to become inflammation in the brain,” Dr. Monje said. “And once there’s inflammation in the brain … that can dysregulate other cell types that normally support healthy cognitive function.”
One issue with the concept of brain fog is that, like the term itself, the condition can be tough to define for doctors and patients alike and difficult, if not impossible, to capture on common cognition tests.
These days, patients often arrive at the Center of Excellence for Alzheimer’s Disease, in Syracuse, N.Y., complaining that they “don’t feel the same” as they did before contracting COVID-19, said Sharon Brangman, MD, the center’s director and the chair of the geriatrics department at Upstate Medical University.
But the evidence of diminished cognition just isn’t there.
“There’s nothing that we can find, objectively, that’s wrong with them,” she said. “They’re not severe enough to score low on mental status testing.”
But specialized, directed testing can find some probable signs, said Dr. Cahan, who evaluates patient cognition in a long COVID clinic at Northwestern University.
He often finds that his long COVID patients score in the low normal range on cognitive testing.
“Patients do have a complaint that something’s changed, and we don’t have prior testing,” he said. “So it’s possible that they were maybe in the high normal range or the superior range, but you just don’t know.”
He said he has seen very high-performing people, such as lawyers, executives, PhDs, and other professionals, who have tests that might be interpreted as normal, but given their level of achievement, “you would expect [higher scores].”
Like Ms. Sanders, many of those who do have muddled thinking after a COVID infection return to their former mental status. A study published in the journal Brain Communications found that people who had recovered from COVID-19, even if they had a mild illness, were significantly more likely to have memory and other cognition issues in the months after infection. But after 9 months, the former COVID patients had returned to their normal level of cognition, the team at Britain’s University of Oxford reported.
Notably, though, the average age of the people in the study was 28.6.
At the Northwestern clinic, Dr. Cahan treats patients who have struggled with COVID-induced cognition issues for months or even years. A rehabilitation program involves working with patients to come up with ways to compensate for cognitive deficits – such as making lists – as well as brain exercises, Dr. Cahan said. Over time, patients may achieve a 75% to 85% improvement, he said.
Dr. Monje hopes that one day, science will come up with ways to fully reverse the decline.
“I think what is likely the most common contributor to brain fog is this neuroinflammation, causing dysfunction of other cell types,” she said. “And, at least in the laboratory, we can rescue that in mouse models of chemotherapy brain fog, which gives me hope that we can rescue that for people.”

People who got COVID-19 were twice as likely to receive a diagnosis of Alzheimer’s disease in the 12 months after infection, compared to those who didn’t get COVID, according to a study published in the journal Nature Medicine , which analyzed the health care databases of the U.S. Department of Veterans Affairs.
Joshua Cahan, MD, a cognitive neurologist at Northwestern University, Chicago, advises caution about applying such a specific label simply from a patient’s medical chart. After all, he noted, few patients get tested to confirm that they have the proteins linked to Alzheimer’s.
“Probably the most appropriate conclusion from that is that there’s an increased risk of dementia after a COVID infection,” he said, “but we don’t know whether it’s truly Alzheimer’s disease or not.”
There could be a number of reasons why COVID-19 triggers a decline in thinking skills, says Michelle Monje, MD, a neuroscientist and neuro-oncologist at Stanford (Calif.) University.
In a paper published in the journal Neuron, Dr. Monje and her coauthor, Akiko Iwasaki, PhD, professor of immunobiology at Yale University, New Haven, Conn., propose possible triggers for brain fog caused by COVID: inflammation in the lungs and respiratory passages that leads to inflammation and dysregulation of the central nervous system; autoimmune reactions that damage the central nervous system; brain infection directly caused by the coronavirus (though, they note, this appears rare); a reactivation of an Epstein-Barr virus, which can lead to neuroinflammation; triggered by the coronavirus; and/or complications from severe cases of COVID-19, possibly involving periods of low blood oxygen and multi-organ failure.
Scientific understanding of brain fog is “part of an emerging picture that inflammation elsewhere in the body can be transmitted to become inflammation in the brain,” Dr. Monje said. “And once there’s inflammation in the brain … that can dysregulate other cell types that normally support healthy cognitive function.”
One issue with the concept of brain fog is that, like the term itself, the condition can be tough to define for doctors and patients alike and difficult, if not impossible, to capture on common cognition tests.
These days, patients often arrive at the Center of Excellence for Alzheimer’s Disease, in Syracuse, N.Y., complaining that they “don’t feel the same” as they did before contracting COVID-19, said Sharon Brangman, MD, the center’s director and the chair of the geriatrics department at Upstate Medical University.
But the evidence of diminished cognition just isn’t there.
“There’s nothing that we can find, objectively, that’s wrong with them,” she said. “They’re not severe enough to score low on mental status testing.”
But specialized, directed testing can find some probable signs, said Dr. Cahan, who evaluates patient cognition in a long COVID clinic at Northwestern University.
He often finds that his long COVID patients score in the low normal range on cognitive testing.
“Patients do have a complaint that something’s changed, and we don’t have prior testing,” he said. “So it’s possible that they were maybe in the high normal range or the superior range, but you just don’t know.”
He said he has seen very high-performing people, such as lawyers, executives, PhDs, and other professionals, who have tests that might be interpreted as normal, but given their level of achievement, “you would expect [higher scores].”
Like Ms. Sanders, many of those who do have muddled thinking after a COVID infection return to their former mental status. A study published in the journal Brain Communications found that people who had recovered from COVID-19, even if they had a mild illness, were significantly more likely to have memory and other cognition issues in the months after infection. But after 9 months, the former COVID patients had returned to their normal level of cognition, the team at Britain’s University of Oxford reported.
Notably, though, the average age of the people in the study was 28.6.
At the Northwestern clinic, Dr. Cahan treats patients who have struggled with COVID-induced cognition issues for months or even years. A rehabilitation program involves working with patients to come up with ways to compensate for cognitive deficits – such as making lists – as well as brain exercises, Dr. Cahan said. Over time, patients may achieve a 75% to 85% improvement, he said.
Dr. Monje hopes that one day, science will come up with ways to fully reverse the decline.
“I think what is likely the most common contributor to brain fog is this neuroinflammation, causing dysfunction of other cell types,” she said. “And, at least in the laboratory, we can rescue that in mouse models of chemotherapy brain fog, which gives me hope that we can rescue that for people.”

In early September, about a week after recovering from COVID-19, Barri Sanders went to the bank to pay a bill. But by mistake, she transferred a large amount of money from the wrong account.
“I’m talking about $20,000,” she said. “I had to go back [later] and fix it.”
Ms. Sanders, 83, had not had confusion like that before. Suddenly, the Albuquerque, N.M., resident found herself looking up from a book and not remembering what she had just read. She would stand up from her chair and forget what she meant to do.
“I kind of thought it was just the aging process,” she said. Combined with sudden balance issues, insomnia, and a nagging postnasal drip, the overall effect was “subtle, but scary,” she said.
After 5 days of this, she went to bed and slept the whole night through. She woke up in the morning to find her balanced restored, her sinuses clear, and the mental fog gone. What she’d had, she realized, wasn’t a rapid start of dementia, but rather a mercifully short form of long COVID.
Somewhere between 22% and 32% of people who recover from COVID-19 get “brain fog,” a nonscientific term used to describe slow or sluggish thinking. While this is disturbing at any age, And some scientists are starting to confirm what doctors, patients, and their families can already see: Older patients who have had COVID-19 have a higher risk of getting dementia or, if they already have mental confusion, the illness may worsen their condition.
British scientists who studied medical records from around the world reported in the journal The Lancet Psychiatry that people who recovered from COVID-19 had a higher risk of problems with their thinking and dementia even after 2 years had passed.
Another 2022 study, published in JAMA Neurology, looked at older COVID-19 patients for a year after they were discharged from hospitals in Wuhan, China. Compared with uninfected people, those who survived a severe case of COVID-19 were at higher risk for early onset, late-onset, and progressive decline in their thinking skills. Those who survived a mild infection were at a higher risk for early onset decline, the study found.
Eran Metzger, MD, assistant professor of psychiatry at Beth Israel Deaconess Medical Center in Boston, said he’s noticed that COVID-19 makes some older patients confused, and their brains don’t regain their former clarity.
