We tend to think a good night’s sleep should be uninterrupted, but surprising new research from the University of Copenhagen suggests just the opposite: Brief awakenings may be a sign you’ve slept well.

The study, done on mice, found that the stress transmitter noradrenaline wakes up the brain many times a night. These “microarousals” were linked to memory consolidation, meaning they help you remember the previous day’s events. In fact, the more “awake” you are during a microarousal, the better the memory boost, suggests the research, which was published in Nature Neuroscience.

“Every time I wake up in the middle of the night now, I think – ah, nice, I probably just had great memory-boosting sleep,” said study author Celia Kjaerby, PhD, an assistant professor at the university’s Center for Translational Neuromedicine.

The findings add insight to what happens in the brain during sleep and may help pave the way for new treatments for those who have sleep disorders.
 

Waves of noradrenaline

Previous research has suggested that noradrenaline – a hormone that increases during stress but also helps you stay focused – is inactive during sleep. So, the researchers were surprised to see high levels of it in the brains of the sleeping rodents.

“I still remember seeing the first traces showing the brain activity of the norepinephrine stress system during sleep. We could not believe our eyes,” Dr. Kjaerby said. “Everyone had thought the system would be quiet. And now we have found out that it completely controls the microarchitecture of sleep.”

Those noradrenaline levels rise and fall like waves every 30 seconds during non-REM (NREM) sleep. At each “peak” the brain is briefly awake, and at each “valley” it is asleep. Typically, these awakenings are so brief that the sleeping subject does not notice. But the higher the rise, the longer the awakening – and the more likely the sleeper may notice.

During the valleys, or when norepinephrine drops, so-called sleep spindles occur.

“These are short oscillatory bursts of brain activity linked to memory consolidation,” Dr. Kjaerby said. Occasionally there is a “deep valley,” lasting 3-5 minutes, leading to more sleep spindles. The mice with the most deep valleys also had the best memories, the researchers noted.

“We have shown that the amount of these super-boosts of sleep spindles, and not REM sleep, defines how well you remember the experiences you had prior to going to sleep,” said Dr. Kjaerby.

Deep valleys were followed by longer awakenings, the researchers observed. So, the longer the valley, the longer the awakening – and the better the memory boost. This means that, though restless sleep is not good, waking up briefly may be a natural part of memory-related sleep phases and may even mean you’ve slept well.
 

What happens in our brains when we sleep: Piecing it together

The findings fit with previous clinical data that shows we wake up roughly 100-plus times a night, mostly during NREM sleep stage 2 (the spindle-rich sleep stage), Dr. Kjaerby said.

Still, more research on these small awakenings is needed, Dr. Kjaerby said, noting that professor Maiken Nedergaard, MD, another author of this study, has found that the brain cleans up waste products through a rinsing fluid system.

“It remains a puzzle why the fluid system is so active when we sleep,” Dr. Kjaerby said. “We believe these short awakenings could potentially be the key to answering this question.”

Consistently earning a low salary in midlife is associated with increased memory decline in older age, new research suggests. In a new analysis of more than 3,000 participants in the Health and Retirement Study, those who sustained low wages in midlife showed significantly faster memory decline than their peers who never earned low wages.

The findings could have implications for future public policy and research initiatives, the investigators noted.

“Our findings, which suggest a pattern of sustained low-wage earning is harmful for cognitive health, [are] broadly applicable to researchers across numerous health disciplines,” said co-investigator Katrina Kezios, PhD, postdoctoral researcher, department of epidemiology, Mailman School of Public Health, Columbia University, New York.

The findings were presented at the 2022 Alzheimer’s Association International Conference.
 

Growing number of low-wage workers

Low-wage workers make up a growing share of the U.S. labor market. Yet little research has examined the long-term relationship between earning low wages and memory decline.

The current investigators assessed 1992-2016 data from the Health and Retirement Study, a longitudinal survey of nationally representative samples of Americans aged 50 years and older. Study participants are interviewed every 2 years and provide, among other things, information on work-related factors, including hourly wages.

Memory function was measured at each visit from 2004 to 2016 using a memory composite score. The score included immediate and delayed word recall memory assessments. For those who became too impaired to complete cognitive assessment, memory tests by proxy informants were utilized.

On average, participants completed 4.8 memory assessments over the course of the study.

Researchers defined “low wage” as an hourly wage lower than two-thirds of the federal median wage for the corresponding year. They categorized low-wage exposure history as “never” or “intermittent” or “sustained” on the basis of wages earned from 1992 to 2004.

The current analysis included 3,803 participants, 1,913 of whom were men. All participants were born from 1936 to 1941. In 2004, the average age was 65 years, and the mean memory score was 1.15 standard units.

The investigators adjusted for factors that could confound the relationship between wages and cognition, including the participant’s education, parental education, household wealth, and marital status. Later, whether the participants’ occupation type was of low skill or not was also included.
 

Cognitive harm

The confounder-adjusted annual rate of memory decline among workers who never earned low wages was –0.12 standard units (95% confidence interval, –0.14 to –0.10).

Compared with these workers, memory decline was significantly faster among participants with sustained low wage–earning during midlife (beta for interaction between time and exposure group, –0.012; 95% CI, –0.02 to 0.01), corresponding to an annual rate of –0.13 standard units.

Put another way, the cognitive aging experienced by workers earning low wages over a 10-year period was equivalent to what workers who never earned low wages would experience over 11 years.

Although similar associations were found for men and women, it was stronger in magnitude for men – a finding Dr. Kezios said was somewhat surprising. She noted that women are commonly more at risk for dementia than men.

However, she advises caution in interpreting this finding, as there were so few men in the sustained low-wage group. “Women disproportionately make up the group of workers earning low wages,” she said.

The negative low coefficient found for those who persistently earned low wages was also observed for those who intermittently earned low wages, but this was not statistically significant.

“We can speculate or hypothesize the cumulative effect of earning low wages at each exposure interval produces more cognitive harm than maybe earning low wages at some time points over that exposure period,” said Dr. Kezios.

A sensitivity analysis that examined wage earning at the same ages but in two different birth cohorts showed similar results for the two groups. When researchers removed self-employed workers from the study sample, the same association between sustained low wages and memory decline was found.

“Our findings held up, which gave us a little more reassurance that what we were seeing is at least signaling there might be something there,” said Dr. Kezios.

She described the study as a “first pass” for documenting the harmful cognitive effects of consistently earning low wages.

It would be interesting, she said, to now determine whether there’s a “dose effect” for having a low salary. However, other studies with different designs would be needed to determine at what income level cognitive health starts to be protected and the impact of raising the minimum wage, she added.
 

Unique study

Heather Snyder, PhD, vice president of medical and scientific relations, Alzheimer’s Association, said the study was unique. “I don’t think we have seen anything like this before,” said Dr. Snyder.

The study, which links sustained low-wage earning in midlife to later memory decline, “is looking beyond some of the other measures we’ve seen when we looked at socioeconomic status,” she noted.

The results “beg the question” of whether people who earn low wages have less access to health care, she added.

“We should think about how to ensure access and equity around health care and around potential ways that may address components of risk individuals have during their life course,” Dr. Snyder said.

She noted that the study provides a “start” at considering potential policies to address the impact of sustained low wages on overall health, particularly cognitive health, throughout life.

The study had no outside funding. Dr. Kezios has reported no relevant financial relationships.

Everyone gets by using environmental cues: For example, if you have to go to use the toilet in public, a bathroom sign prompts an immediate response. However, patients with dementia often struggle with environmental cues, which can complicate the already difficult task faced by their caregivers.

Individuals with dementia can lose awareness of such signs, and even colors, making it harder for them to interpret environmental cues.

A new pilot study showed that a telehealth intervention focusing on individualized treatment and environmental cues can be delivered to patients and caregivers in a rural environment.

The study, presented at the Alzheimer’s Association International Conference, recruited 30 pairs of patients and their caregivers. The approach is based on the Dunn model of sensory processing, which focuses on altering environments to maximize chances of success. It “explains that sensory processing is the information coming in, and then our ability to regulate and habituate to those sensations (creates) behavior,” Elizabeth Rhodus, MD, PhD, said during her talk. Dr. Rhodus is assistant professor of medicine at the University of Kentucky, Lexington.

Sensory-based interventions are not uncommon, but most are applied to pediatric populations and tend to focus on sensory processing disorders and autism spectrum disorder. The few programs that do focus on adults have varying methods and produce mixed results. Dr. Rhodus thinks that the key to success is individualization of therapy. “You’re going to like a certain sensation, and I might not like it. You can’t put us in the same room and expect the same results. We have to identify the preferences of how people interact with their environment, and what their brain does at a neuroscience level with that information,” she said.
 

Caregiving hacks

The program employs telehealth to work with caregivers so they can also create sensory environments within the home, using environment to trigger behavior.

For example, although individuals with dementia may have reduced response to color, the color red is unique. “Red is a cortical trigger. Red always stands out to people, so in our package that we send out as part of this intervention, we send out a roll of red duct tape,” said Dr. Rhodus.

An example of the use of red was a patient with dementia who had stopped drinking on his own, causing his caregiver daughter to be concerned that he would soon have to enter a nursing home. Examining the room, the occupational therapist realized that the water was kept out of sight, and suggested that the water glass be placed within the patient’s view, atop a square created with the red duct tape.

“These are just some of the simple concepts. They kind of seem easy. Some of my participants call them caregiving hacks, but it’s things that are grounded in neuroscience – how the brain processes the environment, and then how can we plug in supports and cues in whatever area is missing,” said Dr. Rhodus.

In the program, the caregiver fills out several online surveys, and an occupational therapist conducts an interview to identify specific challenges, such as bathing, or using the toilet, or going to church. Then an adult sensory profile reveals how the patient perceives his or her environment. “It’s taking those individual pieces, and then boiling it down to these mechanisms at the behavioral and neuroscience level,” said Dr. Rhodus. She said the entire setup process takes about an hour.
 

Impactful care

The individualized approach of the HARMONY (Helping Older Adults Create and Manage Occupations Successfully) method is promising, according to Monika Gross, executive director of the Poise Project, which uses the Alexander Technique to help people with chronic conditions such as Parkinson’s disease.

“Although it’s always a very simple idea that human beings need sensory processing aspects in their lives, from the time they’re infants through to the end of life, we don’t really focus on the end of life in a way that can bring meaning between the care partner and the person living with dementia. The other thing that was impressive is that this is in a rural community, where there often aren’t a lot of resources available, (such as) classes that the care partner can take their loved one to. So having something where the care partner has some confidence that they can really make an impact in that person that they are seeing decline, that they can see their behavior change [is good],” said Ms. Gross.
 

Empowering caregivers

The study included 30 pairs of patients and caregivers who were randomized to the individualized care (I), standardized care, or a control group. Adherence to weekly visits was high (I, 88%; S, 100%; C, 60%; P = .061). Retention was strong (I, 80%; S, 60%; C, 50%).

“It was feasible ... and at the end, we found a significant improvement in care partner satisfaction. We actually empowered these people to care for their loved ones, and in doing that, and helping them set up environmental cues, it allowed that person to perform at a more independent level,” said Dr. Rhodus.

The trial was only a proof of concept, so although the researchers saw signs of efficacy, it wasn’t powered to show that. They are currently enrolling additional patients and caregivers for larger studies to further test the approach.

Dr. Rhodus and Ms. Gross have no relevant financial disclosures.

The individualized approach of the HARMONY (Helping Older Adults Create and Manage Occupations Successfully) method is promising, according to Monika Gross, executive director of the Poise Project, which uses the Alexander Technique to help people with chronic conditions such as Parkinson’s disease.

“Although it’s always a very simple idea that human beings need sensory processing aspects in their lives, from the time they’re infants through to the end of life, we don’t really focus on the end of life in a way that can bring meaning between the care partner and the person living with dementia. The other thing that was impressive is that this is in a rural community, where there often aren’t a lot of resources available, (such as) classes that the care partner can take their loved one to. So having something where the care partner has some confidence that they can really make an impact in that person that they are seeing decline, that they can see their behavior change [is good],” said Ms. Gross.
 

Empowering caregivers

The study included 30 pairs of patients and caregivers who were randomized to the individualized care (I), standardized care, or a control group. Adherence to weekly visits was high (I, 88%; S, 100%; C, 60%; P = .061). Retention was strong (I, 80%; S, 60%; C, 50%).

“It was feasible ... and at the end, we found a significant improvement in care partner satisfaction. We actually empowered these people to care for their loved ones, and in doing that, and helping them set up environmental cues, it allowed that person to perform at a more independent level,” said Dr. Rhodus.

The trial was only a proof of concept, so although the researchers saw signs of efficacy, it wasn’t powered to show that. They are currently enrolling additional patients and caregivers for larger studies to further test the approach.

Dr. Rhodus and Ms. Gross have no relevant financial disclosures.

Everyone gets by using environmental cues: For example, if you have to go to use the toilet in public, a bathroom sign prompts an immediate response. However, patients with dementia often struggle with environmental cues, which can complicate the already difficult task faced by their caregivers.

Individuals with dementia can lose awareness of such signs, and even colors, making it harder for them to interpret environmental cues.

A new pilot study showed that a telehealth intervention focusing on individualized treatment and environmental cues can be delivered to patients and caregivers in a rural environment.

The study, presented at the Alzheimer’s Association International Conference, recruited 30 pairs of patients and their caregivers. The approach is based on the Dunn model of sensory processing, which focuses on altering environments to maximize chances of success. It “explains that sensory processing is the information coming in, and then our ability to regulate and habituate to those sensations (creates) behavior,” Elizabeth Rhodus, MD, PhD, said during her talk. Dr. Rhodus is assistant professor of medicine at the University of Kentucky, Lexington.

Sensory-based interventions are not uncommon, but most are applied to pediatric populations and tend to focus on sensory processing disorders and autism spectrum disorder. The few programs that do focus on adults have varying methods and produce mixed results. Dr. Rhodus thinks that the key to success is individualization of therapy. “You’re going to like a certain sensation, and I might not like it. You can’t put us in the same room and expect the same results. We have to identify the preferences of how people interact with their environment, and what their brain does at a neuroscience level with that information,” she said.
 

Caregiving hacks

The program employs telehealth to work with caregivers so they can also create sensory environments within the home, using environment to trigger behavior.

For example, although individuals with dementia may have reduced response to color, the color red is unique. “Red is a cortical trigger. Red always stands out to people, so in our package that we send out as part of this intervention, we send out a roll of red duct tape,” said Dr. Rhodus.

An example of the use of red was a patient with dementia who had stopped drinking on his own, causing his caregiver daughter to be concerned that he would soon have to enter a nursing home. Examining the room, the occupational therapist realized that the water was kept out of sight, and suggested that the water glass be placed within the patient’s view, atop a square created with the red duct tape.

“These are just some of the simple concepts. They kind of seem easy. Some of my participants call them caregiving hacks, but it’s things that are grounded in neuroscience – how the brain processes the environment, and then how can we plug in supports and cues in whatever area is missing,” said Dr. Rhodus.

In the program, the caregiver fills out several online surveys, and an occupational therapist conducts an interview to identify specific challenges, such as bathing, or using the toilet, or going to church. Then an adult sensory profile reveals how the patient perceives his or her environment. “It’s taking those individual pieces, and then boiling it down to these mechanisms at the behavioral and neuroscience level,” said Dr. Rhodus. She said the entire setup process takes about an hour.

A 4-mm punch biopsy confirmed that this was a case of blaschkitis. This uncommon condition is referred to as adult blaschkitis because it resembles lichen striatus, a linear erythematous papular eruption usually seen in children younger than 15 years of age that erupts along Blaschko lines. The biopsy in this case helped to rule out lichen planus, which can also manifest with an erythematous papular eruption along Blaschko lines.

Adult blaschkitis is thought to be a hypersensitivity reaction involving T cells. It has been linked to medication use, insect stings, trauma, and autoimmune disease.¹ The characteristic linear pattern is due to the inflammatory response following the Blaschko lines of keratinocytes that migrated during the embryonic phase.¹ Post-inflammatory hyperpigmentation is a frequent complication. Topical steroids often help with the itching, but do not usually make the lesions go away. There have been better results in reducing itching and lesion prominence with intralesional steroid injections, topical calcipotriol, or calcineurin inhibitors.¹ The inflammation usually spontaneously resolves over 3 to 12 months.

The patient was advised that the condition is benign and would likely resolve on its own over time. She was counseled that since the clobetasol was helping with her itching, she could use it (sparingly) as needed. She was cautioned that prolonged usage could lead to skin atrophy.

Finding a fiber of good moral fiber

If you’ve ever wandered into the supplement aisle at your local grocery store, you’ve probably noticed an overabundance of fiber supplements that claim to do this for you and benefit that. Since there’s no Food and Drug Administration regulation on fiber supplements, manufacturers are free to (and do) make whatever wild claims they like. And much like choosing which of 500 shows to watch on Netflix, when you’re spoiled for choice, it can be difficult to pick.

Duke University Photo

Enter a team of molecular geneticists and microbiologists from Duke University. They can’t tell you what show to watch next, but they can tell you which fiber to choose, thanks to their new study. And the answer? Yes.

Well that’s not very helpful, but let us explain. For their study, a group of 28 received three of the main fiber supplements (inulin, dextrin, and galactooligosaccharides) for a week each, followed by a week off of fibers for their gut to return to baseline until they’d received all three. Those who consumed the least fiber at baseline saw the greatest benefit from fiber supplementation, with no appreciable difference between the three types. It was the same story for study participants who already consumed enough fiber; because their guts already hosted a more-optimal microbiome, the type of supplement didn’t matter. The benefits were the same across the board.

In an additional study, the Duke researchers found that gut microbiomes reacted to new fiber within a day, being primed to consume fiber on the first dose and digesting it more quickly on the second fiber dose.

The results, the researchers pointed out, make sense, since the average American only consumes 20%-40% of their daily recommended supply of fiber. Our digestive systems aren’t picky; they just want more, so go out there and choose whatever fiber you’d like. Do that, and then feel free to eat as many double bacon cheeseburgers as you’d like. That is the pinnacle of diet right there. Dietitians literally could not complain about it.
 

Jarlsberg vs. Camembert: This time it’s skeletal

Fiber is fabulous, of course, but the road to dietary health and wellness fulfillment takes us to many other, equally wondrous places. Hey, look! This next exit is covered with cheese.

PxHere

All the cheeses are here, from Abbaye de Belloc to Zwitser, and there, right between the jalapeno cheddar and the Jermi tortes you’ll find Jarlsberg, a mild, semisoft, nutty-flavored cheese that comes from Jarlsberg in eastern Norway. A recent study also suggests that Jarlsberg may help to prevent osteopenia and osteoporosis.

A group of Norwegian investigators gathered together 66 healthy women and gave them a daily portion of either Jarlsberg or Camembert for 6 weeks, at which point the Camembert group was switched to Jarlsberg for another 6 weeks.

The research team choose Camembert because of its similarity to Jarlsberg in fat and protein content. Jarlsberg, however, also is rich in vitamin K_{2, which is important for bone health,} and a substance known as DHNA, which “might combat bone thinning and increase bone tissue formation,” they said in a Eurekalert release.

After the first 6 weeks, blood levels of osteocalcin; vitamin K_{2; and} PINP, a peptide involved in bone turnover, were significantly higher in the Jarlsberg group only. All those measures rose significantly after the switch from Camembert to Jarlsberg, while levels of total and LDL cholesterol “fell significantly in the Camembert group after they switched to Jarlsberg,” the team added.

But wait! There’s more! HbA1c fell significantly among those initially eating the Jarlsberg but rose sharply in those eating Camembert. Do you see where this is going? After the Camembert group made the switch to Jarlsberg, their HbA1c levels fell significantly as well.

So it’s not just a cheese thing: The effects are specific to Jarlsberg. Can you guess what we’re having for lunch? Double bacon and fiber Jarlsbergers. Mmm, Jarlsburgers.
 

Luck be a lady: The mother of twins

It’s widely believed that women who have twins must be more fertile, giving birth to more than one child at a time. Some studies have supported the idea, but more recent work is refuting that claim. In actuality, it might just be more statistics and luck than fertility after all.

Those earlier studies supporting fertility didn’t specify whether the chances of twin births were based on the ability to produce more than one egg at a time or on the number of births that women had overall. Looking at 100,000 preindustrial European births, before contraception was available, researchers from Norway, Germany, France, and the United Kingdom found that the number of total births, twins included, makes all the difference.

“When a woman gives birth several times, the chances increase that at least one of these births will be a twin birth,” investigator Gine Roll Skjærvø of the Norwegian University of Science and Technology said in a written statement.

Since twins occur in 1%-3% of all births, the more births that a woman has, the better her chances of giving birth to twins. The researchers compared it to playing the lottery. You buy enough tickets, eventually your numbers are going to come up. Despite that, however, they found that women who give birth to twins give birth less often than those who don’t have twins. Which raises the idea of sheer luck.

The researchers said that there’s still a lot to uncover in twin births, noting that “uncritically comparing groups of women with and without twins can trick us into believing the opposite of what is really true. These groupings may either hide the effects of twinning and fertility genes where they exist, or vice versa, create the illusion of these if they do not exist.”

For now, this new research claims that it’s basically a lottery. And women who give birth to twins hit the jackpot.
 

Those with low wages may be earning future memory loss

Not only are low wages detrimental to our souls, hopes, and dreams, but a new study shows that low wages also are linked to quicker memory decline later in life. Sustained low wages not only cause stress and food insecurity in the lives of many, but they also can cause diseases such as depression, obesity, and high blood pressure, which are risk factors for cognitive aging.

Nicola Barts/Pexels

The study was conducted using records from the Health and Retirement Study for the years 1992-2016 and focused on 2,879 adults born between 1936 and 1941. The participants were divided into three groups: those who never earned low wages, those who sometimes did, and those who always did.

The investigators found that workers who earned sustained low wages – defined as an hourly wage lower than two-thirds of the federal median wage for the corresponding year – “experienced significantly faster memory decline in older age” than did those who never earned low wages.

There are signs of inflation everywhere we look these days, but many people are not earning higher wages to compensate for the extra expenses. “Increasing the federal minimum wage, for example to $15 per hour, remains a gridlock issue in Congress,” lead author Katrina Kezios of the Columbia University Mailman School of Public Health, said in a statement released by the university.

If only salaries would rise instead of prices for once.

Community service (CS) or service learning in dermatology (eg, free skin cancer screenings, providing care through free clinics, free teledermatology consultations) is instrumental in mitigating disparities and improving access to equitable dermatologic care. With the rate of underinsured and uninsured patients on the rise, free and federally qualified clinics frequently are the sole means by which patients access specialty care such as dermatology.¹ Contributing to the economic gap in access, the geographic disparity of dermatologists in the United States continues to climb, and many marginalized communities remain without dermatologists.² Nearly 30% of the total US population resides in geographic areas that are underserved by dermatologists, while there appears to be an oversupply of dermatologists in urban areas.³ Dermatologists practicing in rural areas make up only 10% of the dermatology workforce,⁴ whereas 40% of all dermatologists practice in the most densely populated US cities.⁵ Consequently, patients in these underserved communities face longer wait times⁶ and are less likely to utilize dermatology services than patients in dermatologist-dense geographic areas.⁷

Service opportunities have become increasingly integrated into graduate medical education.⁸ These service activities help bridge the health care access gap while fulfilling Accreditation Council of Graduate Medical Education (ACGME) requirements. Our study assessed the importance of CS to dermatology residency program directors (PDs), dermatology residents, and recent dermatology residency graduates. Herein, we describe the perceptions of CS within dermatology residency training among PDs and residents.

Methods

In this study, CS is defined as participation in activities to increase dermatologic access, education, and resources to underserved communities. Using the approved Association of Professors of Dermatology listserve and direct email communication, we surveyed 142 PDs of ACGME-accredited dermatology residency training programs. The deidentified respondents voluntarily completed a 17-question Qualtrics survey with a 5-point Likert scale (extremely, very, moderately, slightly, or not at all), yes/no/undecided, and qualitative responses.

We also surveyed current dermatology residents and recent graduates of ACGME-accredited dermatology residency programs via PDs nationwide. The deidentified respondents voluntarily completed a 19-question Qualtrics survey with a 5-point Likert scale (extremely, very, moderately, slightly, or not at all), yes/no/undecided, and qualitative responses.

Descriptive statistics were used for data analysis for both Qualtrics surveys. The University of Pittsburgh institutional review board deemed this study exempt.

Results

Feedback From PDs—Of the 142 PDs, we received 78 responses (54.9%). For selection of dermatology residents, CS was moderately to extremely important to 64 (82.1%) PDs, and 63 (80.8%) PDs stated CS was moderately to extremely important to their dermatology residency program at large. For dermatology residency training, 66 (84.6%) PDs believed CS is important, whereas 3 (3.8%) believed it is not important, and 9 (11.5%) remained undecided (Figure 1). Notably, 17 (21.8%) programs required CS as part of the dermatology educational curriculum, with most of these programs requiring 10 hours or less during the 3 years of residency training. Of the programs with required CS, 15 (88.2%) had dermatology-specific CS requirements, with 10 (58.8%) programs involved in CS at free and/or underserved clinics and some programs participating in other CS activities, such as advocacy, mentorship, educational outreach, or sports (Figure 2A).

Community service opportunities were offered to dermatology residents by 69 (88.5%) programs, including the 17 programs that required CS as part of the dermatology educational curriculum. Among these programs with optional CS, 43 (82.7%) PDs reported CS opportunities at free and/or underserved clinics, and 30 (57.7%) reported CS opportunities through global health initiatives (Figure 2B). Other CS opportunities offered included partnerships with community outreach organizations and mentoring underprivileged students. Patient populations that benefit from CS offered by these dermatology residency programs included 55 (79.7%) underserved, 33 (47.8%) minority, 31 (44.9%) immigrant, 14 (20.3%) pediatric, 14 (20.3%) elderly, and 10 (14.5%) rural populations (Figure 2C). At dermatology residency programs with optional CS opportunities, 22 (42.3%) PDs endorsed at least 50% of their residents participating in these activities.

Qualitative responses revealed that some PDs view CS as “a way for residents to stay connected to what drew them to medicine” and “essential to improving perceptions by physicians and patients about dermatology.” Program directors perceived lack of available time, initiative, and resources as well as minimal resident interest, malpractice coverage, and lack of educational opportunities as potential barriers to CS involvement by residents (Table). Forty-six (59.0%) PDs believed that CS should not be an ACGME requirement for dermatology training, 23 (29.5%) believed it should be required, and 9 (11.5%) were undecided.

Feedback From Residents—We received responses from 92 current dermatology residents and recent dermatology residency graduates; 86 (93.5%) respondents were trainees or recent graduates from academic dermatology residency training programs, and 6 (6.5%) were from community-based training programs. Community service was perceived to be an important part of dermatology training by 68 (73.9%) respondents, and dermatology-specific CS opportunities were available to 65 (70.7%) respondents (Figure 1). Although CS was required of only 7 (7.6%) respondents, 36 (39.1%) respondents volunteered at a free dermatology clinic during residency training. Among respondents who were not provided CS opportunities through their residency program, 23 (85.2%) stated they would have participated if given the opportunity.

Dermatology residents listed increased access to care for marginalized populations, increased sense of purpose, increased competence, and decreased burnout as perceived benefits of participation in CS. Of the dermatology residents who volunteered at a free dermatology clinic during training, 27 (75.0%) regarded the experience as a “high-yield learning opportunity.” Additionally, 29 (80.6%) residents stated their participation in a free dermatology clinic increased their awareness of health disparities and societal factors affecting dermatologic care in underserved patient populations. These respondents affirmed that their participation motivated them to become more involved in outreach targeting underserved populations throughout the duration of their careers.

Comment

The results of this nationwide survey have several important implications for dermatology residency programs, with a focus on programs in well-resourced and high socioeconomic status areas. Although most PDs believe that CS is important for dermatology resident training, few programs have CS requirements, and the majority are opposed to ACGME-mandated CS. Dermatology residents and recent graduates overwhelmingly conveyed that participation in a free dermatology clinic during residency training increased their knowledge base surrounding socioeconomic determinants of health and practicing in resource-limited settings. Furthermore, most trainees expressed that CS participation as a resident motivated them to continue to partake in CS for the underserved as an attending physician. The discordance between perceived value of CS by residents and the lack of CS requirements and opportunities by residency programs represents a realistic opportunity for residency training programs to integrate CS into the curriculum.

Residency programs that integrate service for the underserved into their program goals are 3 times more successful in graduating dermatology residents who practice in underserved communities.⁹ Patients in marginalized communities and those from lower socioeconomic backgrounds face many barriers to accessing dermatologic care including longer wait times and higher practice rejection rates than patients with private insurance.⁶ Through increased CS opportunities, dermatology residency programs can strengthen the local health care infrastructure and bridge the gap in access to dermatologic care.

By establishing a formal CS rotation in dermatology residency programs, residents will experience invaluable first-hand educational opportunities, provide comprehensive care for patients in resource-limited settings, and hopefully continue to serve in marginalized communities. Incorporating service for the underserved into the dermatology residency curriculum not only enhances the cultural competency of trainees but also mandates that skin health equity be made a priority. By exposing dermatology residents to the diverse patient populations often served by free clinics, residents will increase their knowledge of skin disease presentation in patients with darker skin tones, which has historically been deficient in medical education.^10,11

The limitations of this survey study included recall bias, the response rate of PDs (54.9%), and the inability to determine response rate of residents, as we were unable to establish the total number of residents who received our survey. Based on geographic location, some dermatology residency programs may treat a high percentage of medically underserved patients, which already improves access to dermatology. For this reason, follow-up studies correlating PD and resident responses with region, program size, and university/community affiliation will increase our understanding of CS participation and perceptions.

Conclusion

Dermatology residency program participation in CS helps reduce barriers to access for patients in marginalized communities. Incorporating CS into the dermatology residency program curriculum creates a rewarding training environment that increases skin health equity, fosters an interest in health disparities, and enhances the cultural competency of its trainees.

Community service (CS) or service learning in dermatology (eg, free skin cancer screenings, providing care through free clinics, free teledermatology consultations) is instrumental in mitigating disparities and improving access to equitable dermatologic care. With the rate of underinsured and uninsured patients on the rise, free and federally qualified clinics frequently are the sole means by which patients access specialty care such as dermatology.¹ Contributing to the economic gap in access, the geographic disparity of dermatologists in the United States continues to climb, and many marginalized communities remain without dermatologists.² Nearly 30% of the total US population resides in geographic areas that are underserved by dermatologists, while there appears to be an oversupply of dermatologists in urban areas.³ Dermatologists practicing in rural areas make up only 10% of the dermatology workforce,⁴ whereas 40% of all dermatologists practice in the most densely populated US cities.⁵ Consequently, patients in these underserved communities face longer wait times⁶ and are less likely to utilize dermatology services than patients in dermatologist-dense geographic areas.⁷

Service opportunities have become increasingly integrated into graduate medical education.⁸ These service activities help bridge the health care access gap while fulfilling Accreditation Council of Graduate Medical Education (ACGME) requirements. Our study assessed the importance of CS to dermatology residency program directors (PDs), dermatology residents, and recent dermatology residency graduates. Herein, we describe the perceptions of CS within dermatology residency training among PDs and residents.

As residents, it is important to understand the steps of the manicuring process and be able to inform patients on how to maintain optimal nail health while continuing to go to nail salons. Most patients are not aware of the possible allergic, traumatic, and/or infectious complications of manicuring their nails. There are practical steps that can be taken to prevent nail issues, such as avoiding cutting one’s cuticles or using allergen-free nail polishes. These simple fixes can make a big difference in long-term nail health in our patients.

Nail Polish Application Process

The nails are first soaked in a warm soapy solution to soften the nail plate and cuticles.¹ Then the nail tips and plates are filed and occasionally are smoothed with a drill. The cuticles are cut with a cuticle cutter. Nail polish—base coat, color enamel, and top coat—is then applied to the nail. Acrylic or sculptured nails and gel and dip manicures are composed of chemical monomers and polymers that harden either at room temperature or through UV or light-emitting diode (LED) exposure. The chemicals in these products can damage nails and cause allergic reactions.

Contact Dermatitis

Approximately 2% of individuals have been found to have allergic or irritant contact dermatitis to nail care products. The top 5 allergens implicated in nail products are (1) 2-hydroxyethyl methacrylate, (2) methyl methacrylate, (3) ethyl acrylate, (4) ethyl-2-cyanoacrylate, and (5) tosylamide.² Methyl methacrylate was banned in 1974 by the US Food and Drug Administration due to reports of severe contact dermatitis, paronychia, and nail dystrophy.³ Due to their potent sensitizing effects, acrylates were named the contact allergen of the year in 2012 by the American Contact Dermatitis Society.³

Acrylates are plastic products formed by polymerization of acrylic or methacrylic acid.⁴ Artificial sculptured nails are created by mixing powdered polymethyl methacrylate polymers and liquid ethyl or isobutyl methacrylate monomers and then applying this mixture to the nail plate.⁵ Gel and powder nails employ a mixture that is similar to acrylic powders, which require UV or LED radiation to polymerize and harden on the nail plate.

Tosylamide, or tosylamide formaldehyde resin, is another potent allergen that promotes adhesion of the enamel to the nail.⁶ It is important to note that sensitization may develop months to years after using artificial nails.

Clinical features of contact allergy secondary to nail polish can vary. Some patients experience severe periungual dermatitis. Others can present with facial or eyelid dermatitis due to exposure to airborne particles of acrylates or from contact with fingertips bearing acrylic nails.^6,7 If inhaled, acrylates also can cause wheezing asthma or allergic rhinoconjunctivitis.

Common Onychodystrophies

Damage to the natural nail plate is inevitable with continued wear of sculptured nails. With 2 to 4 months of consecutive wear, the natural nails turn yellow, brittle, and weak.⁵ One study noted that the thickness of an individual’s left thumb nail plate thinned from 0.059 cm to 0.03 cm after a gel manicure was removed from the nail.⁸ Nail injuries due to manicuring include keratin granulations, onycholysis, pincer nail deformities, pseudopsoriatic nails, lamellar onychoschizia, transverse leukonychia, and ingrown nails.⁶ One interesting nail dystrophy reported secondary to gel manicures is pterygium inversum unguis or a ventral pterygium that causes an abnormal painful adherence of the hyponychium to the ventral surface of the nail plate. Patients prone to developing pterygium inversum unguis can experience sensitivity, pain, or burning sensations during LED or UVA light exposure.⁹

Infections

In addition to contact allergies and nail dystrophies, each step of the manicuring process, such as cutting cuticles, presents opportunities for infectious agents to enter the nail fold. Acute or chronic paronychia, or inflammation of the nail fold, most commonly is caused by bacterial infections with Staphylococcus aureus. Green nail syndrome caused by Pseudomonas aeruginosa also is common.¹ Onychomycosis due to Trichophyton rubrum is one of the most frequent fungal infections contracted at nail salons. Mycobacteria such as Mycobacterium fortuitum also have been implicated in infections from salons, as they can be found in the jets of pedicure spas, which are not sanitized regularly.¹⁰

Final Thoughts

Nail cosmetics are an integral part of many patients’ lives. Being able to educate yourself and your patients on the hazards of nail salons can help them avoid painful infections, contact allergies, and acute to chronic nail deformities. It is important for residents to be aware of the different dermatoses that can arise in men and women who frequent nail salons as the popularity of the nail beauty industry continues to rise.

The chemicals in these products can damage nails and cause allergic reactions.

Contact Dermatitis

Approximately 2% of individuals have been found to have allergic or irritant contact dermatitis to nail care products. The top 5 allergens implicated in nail products are (1) 2-hydroxyethyl methacrylate, (2) methyl methacrylate, (3) ethyl acrylate, (4) ethyl-2-cyanoacrylate, and (5) tosylamide.² Methyl methacrylate was banned in 1974 by the US Food and Drug Administration due to reports of severe contact dermatitis, paronychia, and nail dystrophy.³ Due to their potent sensitizing effects, acrylates were named the contact allergen of the year in 2012 by the American Contact Dermatitis Society.³

Acrylates are plastic products formed by polymerization of acrylic or methacrylic acid.⁴ Artificial sculptured nails are created by mixing powdered polymethyl methacrylate polymers and liquid ethyl or isobutyl methacrylate monomers and then applying this mixture to the nail plate.⁵ Gel and powder nails employ a mixture that is similar to acrylic powders, which require UV or LED radiation to polymerize and harden on the nail plate.

Tosylamide, or tosylamide formaldehyde resin, is another potent allergen that promotes adhesion of the enamel to the nail.⁶ It is important to note that sensitization may develop months to years after using artificial nails.

Clinical features of contact allergy secondary to nail polish can vary. Some patients experience severe periungual dermatitis. Others can present with facial or eyelid dermatitis due to exposure to airborne particles of acrylates or from contact with fingertips bearing acrylic nails.^6,7 If inhaled, acrylates also can cause wheezing asthma or allergic rhinoconjunctivitis.

Common Onychodystrophies

Damage to the natural nail plate is inevitable with continued wear of sculptured nails. With 2 to 4 months of consecutive wear, the natural nails turn yellow, brittle, and weak.⁵ One study noted that the thickness of an individual’s left thumb nail plate thinned from 0.059 cm to 0.03 cm after a gel manicure was removed from the nail.⁸ Nail injuries due to manicuring include keratin granulations, onycholysis, pincer nail deformities, pseudopsoriatic nails, lamellar onychoschizia, transverse leukonychia, and ingrown nails.⁶ One interesting nail dystrophy reported secondary to gel manicures is pterygium inversum unguis or a ventral pterygium that causes an abnormal painful adherence of the hyponychium to the ventral surface of the nail plate. Patients prone to developing pterygium inversum unguis can experience sensitivity, pain, or burning sensations during LED or UVA light exposure.⁹

Infections

In addition to contact allergies and nail dystrophies, each step of the manicuring process, such as cutting cuticles, presents opportunities for infectious agents to enter the nail fold. Acute or chronic paronychia, or inflammation of the nail fold, most commonly is caused by bacterial infections with Staphylococcus aureus. Green nail syndrome caused by Pseudomonas aeruginosa also is common.¹ Onychomycosis due to Trichophyton rubrum is one of the most frequent fungal infections contracted at nail salons. Mycobacteria such as Mycobacterium fortuitum also have been implicated in infections from salons, as they can be found in the jets of pedicure spas, which are not sanitized regularly.¹⁰

Final Thoughts

Nail cosmetics are an integral part of many patients’ lives. Being able to educate yourself and your patients on the hazards of nail salons can help them avoid painful infections, contact allergies, and acute to chronic nail deformities. It is important for residents to be aware of the different dermatoses that can arise in men and women who frequent nail salons as the popularity of the nail beauty industry continues to rise.

An AI-guided analysis of more than 1,000 human lung transcriptomic datasets found that COVID-19 resembles idiopathic pulmonary fibrosis (IPF) at a fundamental level, according to a study published in eBiomedicine, part of The Lancet Discovery Science.

In the aftermath of COVID-19, a significant number of patients develop a fibrotic lung disease, for which insights into pathogenesis, disease models, or treatment options are lacking, according to researchers Dr. Sinha and colleagues. This long-haul form of the disease culminates in a fibrotic type of interstitial lung disease (ILD). While the actual prevalence of post–COVID-19 ILD (PCLD) is still emerging, early analysis indicates that more than a third of COVID-19 survivors develop fibrotic abnormalities, according to the authors.

Previous research has shown that one of the important determinants for PCLD is the duration of disease. Among patients who developed fibrosis, approximately 4% of patients had a disease duration of less than 1 week; approximately 24% had a disease duration between 1 and 3 weeks; and around 61% had a disease duration longer than 3 weeks, the authors stated.

The lung transcriptomic datasets compared in their study were associated with various lung conditions. The researchers used two viral pandemic signatures (ViP and sViP) and one COVID lung-derived signature. They found that the resemblances included that COVID-19 recapitulates the gene expression patterns (ViP and IPF signatures), cytokine storm (IL15-centric), and the AT2 cytopathic changes, for example, injury, DNA damage, arrest in a transient, damage-induced progenitor state, and senescence-associated secretory phenotype (SASP).

In laboratory experiments, Dr. Sinha and colleagues were able to induce these same immunocytopathic features in preclinical COVID-19 models (human adult lung organoid and hamster) and to reverse them in the hamster model with effective anti–CoV-2 therapeutics.

PPI-network analyses pinpointed endoplasmic reticulum (ER) stress as one of the shared early triggers of both IPF and COVID-19, and immunohistochemistry studies validated the same in the lungs of deceased subjects with COVID-19 and the SARS-CoV-2–challenged hamster lungs. Additionally, lungs from transgenic mice, in which ER stress was induced specifically in the AT2 cells, faithfully recapitulated the host immune response and alveolar cytopathic changes that are induced by SARS-CoV-2.

“In this work, we found that a blood-based gene expression biomarker, which works for prognostication in COVID, also works for IPF,” stated corresponding author Pradipta Ghosh, MD, professor in the departments of medicine and cellular and molecular medicine, University of California, San Diego. “If proven in prospective studies, this biomarker could indicate who is at greatest risk for progressive fibrosis and may require lung transplantation,” she said in an interview.

Dr. Ghosh stated further, “When it comes to therapeutics in COVID lung or IPF, we also found that shared fundamental pathogenic mechanisms present excellent opportunities for developing therapeutics that can arrest the fibrogenic drivers in both diseases. One clue that emerged is a specific cytokine that is at the heart of the smoldering inflammation which is invariably associated with fibrosis. That is interleukin 15 [IL-15] and its receptor.” Dr. Ghosh observed that there are two Food and Drug Administration–approved drugs for IPF. “None are very effective in arresting this invariably fatal disease. Hence, finding better options to treat IPF is an urgent and an unmet need.”

Preclinical testing of hypotheses, Dr. Ghosh said, is next on the path to clinical trials. “We have the advantage of using human lung organoids (mini-lungs grown using stem cells) in a dish, adding additional cells to the system (like fibroblasts and immune cells), infecting them with the virus, or subjecting them to the IL-15 cytokine and monitoring lung fibrosis progression in a dish. Anti–IL-15 therapy can then be initiated to observe reversal of the fibrogenic cascade.” Hamsters have also been shown to provide appropriate models for mimicking lung fibrosis, Dr. Ghosh said. 

“The report by Sinha and colleagues describes the fascinating similarities between drivers of post-COVID lung disease and idiopathic pulmonary fibrosis,” stated David Bowton, MD, professor emeritus, section on critical care, department of anesthesiology, Wake Forest University, Winston-Salem, N.C., in an interview. He added that, “Central to the mechanisms of induction of fibrosis in both disorders appears to be endoplasmic reticulum stress in alveolar type II cells (AT2). ER stress induces the unfolded protein response (UPR) that halts protein translation and promotes the degradation of misfolded proteins. Prolonged UPR can reprogram the cell or trigger apoptosis pathways. ER stress in the lung has been reported in a variety of cell lines including AT2 in IPF, bronchial and alveolar epithelial cells in asthma and [chronic obstructive pulmonary disease], and endothelial cells in pulmonary hypertension.”

Dr. Bowton commented further, including a caution, “Sinha and colleagues suggest that the identification of these gene signatures and mechanisms will be a fruitful avenue for developing effective therapeutics for IPF and other fibrotic lung diseases. I am hopeful that these data may offer clues that expedite this process.  However, the redundancy of triggers for effector pathways in biologic systems argues that, even if successful, this will be [a] long and fraught process.”

ABSTRACT

Background: Medical assistant (MA) roles have expanded rapidly as primary care has evolved and MAs take on new patient care duties. Research that looks at the MA experience and factors that enhance or reduce efficiency among MAs is limited.

Methods: We surveyed all MAs working in 6 clinics run by a large academic family medicine department in Ann Arbor, Michigan. MAs deemed by peers as “most efficient” were selected for follow-up interviews. We evaluated personal strategies for efficiency, barriers to efficient care, impact of physician actions on efficiency, and satisfaction.

Results: A total of 75/86 MAs (87%) responded to at least some survey questions and 61/86 (71%) completed the full survey. We interviewed 18 MAs face to face. Most saw their role as essential to clinic functioning and viewed health care as a personal calling. MAs identified common strategies to improve efficiency and described the MA role to orchestrate the flow of the clinic day. Staff recognized differing priorities of patients, staff, and physicians and articulated frustrations with hierarchy and competing priorities as well as behaviors that impeded clinic efficiency. Respondents emphasized the importance of feeling valued by others on their team.

Conclusions: With the evolving demands made on MAs’ time, it is critical to understand how the most effective staff members manage their role and highlight the strategies they employ to provide efficient clinical care. Understanding factors that increase or decrease MA job satisfaction can help identify high-efficiency practices and promote a clinic culture that values and supports all staff.

As primary care continues to evolve into more team-based practice, the role of the medical assistant (MA) has rapidly transformed.¹ Staff may assist with patient management, documentation in the electronic medical record, order entry, pre-visit planning, and fulfillment of quality metrics, particularly in a Primary Care Medical Home (PCMH).² From 2012 through 2014, MA job postings per graduate increased from 1.3 to 2.3, suggesting twice as many job postings as graduates.³ As the demand for experienced MAs increases, the ability to recruit and retain high-performing staff members will be critical.

MAs are referenced in medical literature as early as the 1800s.⁴ The American Association of Medical Assistants was founded in 1956, which led to educational standardization and certifications.⁵ Despite the important role that MAs have long played in the proper functioning of a medical clinic—and the knowledge that team configurations impact a clinic’s efficiency and quality^6,7—few investigations have sought out the MA’s perspective.^8,9 Given the increasing clinical demands placed on all members of the primary care team (and the burnout that often results), it seems that MA insights into clinic efficiency could be valuable.

METHODS

This cross-sectional study was conducted from February to April 2019 at a large academic institution with 6 regional ambulatory care family medicine clinics, each one with 11,000 to 18,000 patient visits annually. Faculty work at all 6 clinics and residents at 2 of them. All MAs are hired, paid, and managed by a central administrative department rather than by the family medicine department. The family medicine clinics are currently PCMH certified, with a mix of fee-for-service and capitated reimbursement.

We developed and piloted a voluntary, anonymous 39-question (29 closed-ended and 10 brief open-ended) online Qualtrics survey, which we distributed via an email link to all the MAs in the department. The survey included clinic site, years as an MA, perceptions of the clinic environment, perception of teamwork at their site, identification of efficient practices, and feedback for physicians to improve efficiency and flow. Most questions were Likert-style with 5 choices ranging from “strongly agree” to “strongly disagree” or short answer. Age and gender were omitted to protect confidentiality, as most MAs in the department are female. Participants could opt to enter in a drawing for three $25 gift cards. The survey was reviewed by the University of Michigan Institutional Review Board and deemed exempt.
 

Seventy-five percent of MAs reported preclinic huddles to plan for patient care were helpful, but only half said huddles took place “always” or “most of the time.”

We asked MAs to nominate peers in their clinic who were “especially efficient and do their jobs well—people that others can learn from.” The staff members who were nominated most frequently by their peers were invited to share additional perspectives via a 10- to 30-minute semi-structured interview with the first author. Interviews covered highly efficient practices, barriers and facilitators to efficient care, and physician behaviors that impaired efficiency. We interviewed a minimum of 2 MAs per clinic and increased the number of interviews through snowball sampling, as needed, to reach data saturation (eg, the point at which we were no longer hearing new content). MAs were assured that all comments would be anonymized. There was no monetary incentive for the interviews. The interviewer had previously met only 3 of the 18 MAs interviewed.

Analysis. Summary statistics were calculated for quantitative data. To compare subgroups (such as individual clinics), a chi-square test was used. In cases when there were small cell sizes (< 5 subjects), we used the Fisher’s Exact test. Qualitative data was collected with real-time typewritten notes during the interviews to capture ideas and verbatim quotes when possible. We also included open-ended comments shared on the Qualtrics survey. Data were organized by theme using a deductive coding approach. Both authors reviewed and discussed observations, and coding was conducted by the first author. Reporting followed the STROBE Statement checklist for cross-sectional studies.¹⁰ Results were shared with MAs, supervisory staff, and physicians, which allowed for feedback and comments and served as “member-checking.” MAs reported that the data reflected their lived experiences.

Continue to: RESULTS...

RESULTS

Surveys were distributed to all 86 MAs working in family medicine clinics. A total of 75 (87%) responded to at least some questions (typically just demographics). We used those who completed the full survey (n = 61; 71%) for data analysis. Eighteen MAs participated in face-to-face interviews. Among respondents, 35 (47%) had worked at least 10 years as an MA and 21 (28%) had worked at least a decade in the family medicine department.

Perception of role

All respondents (n = 61; 100%) somewhat or strongly agreed that the MA role was “very important to keep the clinic functioning” and 58 (95%) reported that working in health care was “a calling” for them. Only 7 (11%) agreed that family medicine was an easier environment for MAs compared to a specialty clinic; 30 (49%) disagreed with this. Among respondents, 32 (53%) strongly or somewhat agreed that their work was very stressful and just half (n = 28; 46%) agreed there were adequate MA staff at their clinic.

Efficiency and competing priorities

MAs described important work values that increased their efficiency. These included clinic culture (good communication and strong teamwork), as well as individual strategies such as multitasking, limiting patient conversations, and doing tasks in a consistent way to improve accuracy. (See TABLE 1.) They identified ways physicians bolster or hurt efficiency and ways in which the relationship between the physician and the MA shapes the MA’s perception of their value in clinic.

When asked about “pet peeves,” a few MAs advised that physicians should not “talk down” to staff and should try to teach rather than criticize.

Communication was emphasized as critical for efficient care, and MAs encouraged the use of preclinic huddles and communication as priorities. Seventy-five percent of MAs reported preclinic huddles to plan for patient care were helpful, but only half said huddles took place “always” or “most of the time.” Many described reviewing the schedule and completing tasks ahead of patient arrival as critical to efficiency.

Participants described the tension between their identified role of orchestrating clinic flow and responding to directives by others that disrupted the flow. Several MAs found it challenging when physicians agreed to see very late patients and felt frustrated when decisions that changed the flow were made by the physician or front desk staff without including the MA. MAs were also able to articulate how they managed competing priorities within the clinic, such as when a patient- or physician-driven need to extend appointments was at odds with maintaining a timely schedule. They were eager to share personal tips for time management and prided themselves on careful and accurate performance and skills they had learned on the job. MAs also described how efficiency could be adversely affected by the behaviors or attitudes of physicians. (See TABLE 2.)

Continue to: Clinic environment...

Clinic environment

Thirty-six MAs (59%) reported that other MAs on their team were willing to help them out in clinic “a great deal” or “a lot” of the time, by helping to room a patient, acting as a chaperone for an exam, or doing a point-of-care lab. This sense of support varied across clinics (38% to 91% reported good support), suggesting that cultures vary by site. Some MAs expressed frustration at peers they saw as resistant to helping, exemplified by this verbatim quote from an interview:

“Some don’t want to help out. They may sigh. It’s how they react—you just know.” (Clinic #1, MA #2 interview)

Efficient MAs stressed the need for situational awareness to recognize when co-workers need help:

“[Peers often] are not aware that another MA is drowning. There’s 5 people who could have done that, and here I am running around and nobody budged.” (Clinic #5, MA #2 interview)

A minority of staff used the open-ended survey sections to describe clinic hierarchy. When asked about “pet peeves,” a few advised that physicians should not “talk down” to staff and should try to teach rather than criticize. Another asked that physicians not “bark orders” or have “low gratitude” for staff work. MAs found micromanaging stressful—particularly when the physician prompted the MA about patient arrivals:

“[I don’t like] when providers will make a comment about a patient arriving when you already know this information. You then rush to put [the] patient in [a] room, then [the] provider ends up making [the] patient wait an extensive amount of time. I’m perfectly capable of knowing when a patient arrives.” (Clinic #6, survey)
 

MAs did not like physicians “talking bad about us” or blaming the MA if the clinic is running behind.
 

Despite these concerns, most MAs reported feeling appreciated for the job they do. Only 10 (16%) reported that the people they work with rarely say “thank you,” and 2 (3%) stated they were not well supported by the physicians in clinic. Most (n = 38; 62%) strongly agreed or agreed that they felt part of the team and that their opinions matter. In the interviews, many expanded on this idea:

“I really feel like I’m valued, so I want to do everything I can to make [my doctor’s] day go better. If you want a good clinic, the best thing a doc can do is make the MA feel valued.” (Clinic #1, MA #1 interview)

Continue to: DISCUSSION...

DISCUSSION

Participants described their role much as an orchestra director, with MAs as the key to clinic flow and timeliness.⁹ Respondents articulated multiple common strategies used to increase their own efficiency and clinic flow; these may be considered best practices and incorporated as part of the basic training. Most MAs reported their day-to-day jobs were stressful and believed this was underrecognized, so efficiency strategies are critical. With staff completing multiple time-sensitive tasks during clinic, consistent co-worker support is crucial and may impact efficiency.⁸ Proper training of managers to provide that support and ensure equitable workloads may be one strategy to ensure that staff members feel the workplace is fair and collegial.

Several comments reflected the power differential within medical offices. One study reported that MAs and physicians “occupy roles at opposite ends of social and occupational hierarchies.”¹¹ It’s important for physicians to be cognizant of these patterns and clinic culture, as reducing a hierarchy-based environment will be appreciated by MAs.⁹ Prior research has found that MAs have higher perceptions of their own competence than do the physicians working with them.¹² If there is a fundamental lack of trust between the 2 groups, this will undoubtedly hinder team-building. Attention to this issue is key to a more favorable work environment.

Almost all respondents reported health care was a “calling,” which mirrors physician research that suggests seeing work as a “calling” is protective against burnout.^13,14 Open-ended comments indicated great pride in contributions, and most staff members felt appreciated by their teams. Many described the working relationships with physicians as critical to their satisfaction at work and indicated that strong partnerships motivated them to do their best to make the physician’s day easier. Staff job satisfaction is linked to improved quality of care, so treating staff well contributes to high-value care for patients.¹⁵ We also uncovered some MA “pet peeves” that hinder efficiency and could be shared with physicians to emphasize the importance of patience and civility.

One barrier to expansion of MA roles within PCMH practices is the limited pay and career ladder for MAs who adopt new job responsibilities that require advanced skills or training.^1,2 The mean MA salary at our institution ($37,372) is higher than in our state overall ($33,760), which may impact satisfaction.¹⁶ In addition, 93% of MAs are women; thus, they may continue to struggle more with lower pay than do workers in male- dominated professions.^17,18 Expected job growth from 2018-2028 is predicted at 23%, which may help to boost salaries. ¹⁹  Prior studies describe the lack of a job ladder or promotion opportunities as a challenge^1,20; this was not formally assessed in our study.


Prior research has found that MAs have higher perceptions of their own competence than do the physicians working with them.

MAs see work in family medicine as much harder than it is in other   specialty clinics. Being trusted with more responsibility, greater autonomy,^21-23 and expanded patient care roles can boost MA self-efficacy, which can reduce burnout for both physicians and MAs. ^8,24  However, new responsibilities should include appropriate training, support, and compensation, and match staff interests.⁷

Study limitations. The study was limited to 6 clinics in 1 department at a large academic medical center. Interviewed participants were selected by convenience and snowball sampling and thus, the results cannot be generalized to the population of MAs as a whole. As the initial interview goal was simply to gather efficiency tips, the project was not designed to be formal qualitative research. However, the discussions built on open-ended comments from the written survey helped contextualize our quantitative findings about efficiency. Notes were documented in real time by a single interviewer with rapid typing skills, which allowed capture of quotes verbatim. Subsequent studies would benefit from more formal qualitative research methods (recording and transcribing interviews, multiple coders to reduce risk of bias, and more complex thematic analysis).

ABSTRACT

Background: Medical assistant (MA) roles have expanded rapidly as primary care has evolved and MAs take on new patient care duties. Research that looks at the MA experience and factors that enhance or reduce efficiency among MAs is limited.

Methods: We surveyed all MAs working in 6 clinics run by a large academic family medicine department in Ann Arbor, Michigan. MAs deemed by peers as “most efficient” were selected for follow-up interviews. We evaluated personal strategies for efficiency, barriers to efficient care, impact of physician actions on efficiency, and satisfaction.

Results: A total of 75/86 MAs (87%) responded to at least some survey questions and 61/86 (71%) completed the full survey. We interviewed 18 MAs face to face. Most saw their role as essential to clinic functioning and viewed health care as a personal calling. MAs identified common strategies to improve efficiency and described the MA role to orchestrate the flow of the clinic day. Staff recognized differing priorities of patients, staff, and physicians and articulated frustrations with hierarchy and competing priorities as well as behaviors that impeded clinic efficiency. Respondents emphasized the importance of feeling valued by others on their team.

Conclusions: With the evolving demands made on MAs’ time, it is critical to understand how the most effective staff members manage their role and highlight the strategies they employ to provide efficient clinical care. Understanding factors that increase or decrease MA job satisfaction can help identify high-efficiency practices and promote a clinic culture that values and supports all staff.

As primary care continues to evolve into more team-based practice, the role of the medical assistant (MA) has rapidly transformed.¹ Staff may assist with patient management, documentation in the electronic medical record, order entry, pre-visit planning, and fulfillment of quality metrics, particularly in a Primary Care Medical Home (PCMH).² From 2012 through 2014, MA job postings per graduate increased from 1.3 to 2.3, suggesting twice as many job postings as graduates.³ As the demand for experienced MAs increases, the ability to recruit and retain high-performing staff members will be critical.

MAs are referenced in medical literature as early as the 1800s.⁴ The American Association of Medical Assistants was founded in 1956, which led to educational standardization and certifications.⁵ Despite the important role that MAs have long played in the proper functioning of a medical clinic—and the knowledge that team configurations impact a clinic’s efficiency and quality^6,7—few investigations have sought out the MA’s perspective.^8,9 Given the increasing clinical demands placed on all members of the primary care team (and the burnout that often results), it seems that MA insights into clinic efficiency could be valuable.

METHODS

This cross-sectional study was conducted from February to April 2019 at a large academic institution with 6 regional ambulatory care family medicine clinics, each one with 11,000 to 18,000 patient visits annually. Faculty work at all 6 clinics and residents at 2 of them. All MAs are hired, paid, and managed by a central administrative department rather than by the family medicine department. The family medicine clinics are currently PCMH certified, with a mix of fee-for-service and capitated reimbursement.

We developed and piloted a voluntary, anonymous 39-question (29 closed-ended and 10 brief open-ended) online Qualtrics survey, which we distributed via an email link to all the MAs in the department. The survey included clinic site, years as an MA, perceptions of the clinic environment, perception of teamwork at their site, identification of efficient practices, and feedback for physicians to improve efficiency and flow. Most questions were Likert-style with 5 choices ranging from “strongly agree” to “strongly disagree” or short answer. Age and gender were omitted to protect confidentiality, as most MAs in the department are female. Participants could opt to enter in a drawing for three $25 gift cards. The survey was reviewed by the University of Michigan Institutional Review Board and deemed exempt.
 

Seventy-five percent of MAs reported preclinic huddles to plan for patient care were helpful, but only half said huddles took place “always” or “most of the time.”

We asked MAs to nominate peers in their clinic who were “especially efficient and do their jobs well—people that others can learn from.” The staff members who were nominated most frequently by their peers were invited to share additional perspectives via a 10- to 30-minute semi-structured interview with the first author. Interviews covered highly efficient practices, barriers and facilitators to efficient care, and physician behaviors that impaired efficiency. We interviewed a minimum of 2 MAs per clinic and increased the number of interviews through snowball sampling, as needed, to reach data saturation (eg, the point at which we were no longer hearing new content). MAs were assured that all comments would be anonymized. There was no monetary incentive for the interviews. The interviewer had previously met only 3 of the 18 MAs interviewed.

Analysis. Summary statistics were calculated for quantitative data. To compare subgroups (such as individual clinics), a chi-square test was used. In cases when there were small cell sizes (< 5 subjects), we used the Fisher’s Exact test. Qualitative data was collected with real-time typewritten notes during the interviews to capture ideas and verbatim quotes when possible. We also included open-ended comments shared on the Qualtrics survey. Data were organized by theme using a deductive coding approach. Both authors reviewed and discussed observations, and coding was conducted by the first author. Reporting followed the STROBE Statement checklist for cross-sectional studies.¹⁰ Results were shared with MAs, supervisory staff, and physicians, which allowed for feedback and comments and served as “member-checking.” MAs reported that the data reflected their lived experiences.

Continue to: RESULTS...

RESULTS

Surveys were distributed to all 86 MAs working in family medicine clinics. A total of 75 (87%) responded to at least some questions (typically just demographics). We used those who completed the full survey (n = 61; 71%) for data analysis. Eighteen MAs participated in face-to-face interviews. Among respondents, 35 (47%) had worked at least 10 years as an MA and 21 (28%) had worked at least a decade in the family medicine department.

Perception of role

All respondents (n = 61; 100%) somewhat or strongly agreed that the MA role was “very important to keep the clinic functioning” and 58 (95%) reported that working in health care was “a calling” for them. Only 7 (11%) agreed that family medicine was an easier environment for MAs compared to a specialty clinic; 30 (49%) disagreed with this. Among respondents, 32 (53%) strongly or somewhat agreed that their work was very stressful and just half (n = 28; 46%) agreed there were adequate MA staff at their clinic.

Efficiency and competing priorities

MAs described important work values that increased their efficiency. These included clinic culture (good communication and strong teamwork), as well as individual strategies such as multitasking, limiting patient conversations, and doing tasks in a consistent way to improve accuracy. (See TABLE 1.) They identified ways physicians bolster or hurt efficiency and ways in which the relationship between the physician and the MA shapes the MA’s perception of their value in clinic.

When asked about “pet peeves,” a few MAs advised that physicians should not “talk down” to staff and should try to teach rather than criticize.

Communication was emphasized as critical for efficient care, and MAs encouraged the use of preclinic huddles and communication as priorities. Seventy-five percent of MAs reported preclinic huddles to plan for patient care were helpful, but only half said huddles took place “always” or “most of the time.” Many described reviewing the schedule and completing tasks ahead of patient arrival as critical to efficiency.

Participants described the tension between their identified role of orchestrating clinic flow and responding to directives by others that disrupted the flow. Several MAs found it challenging when physicians agreed to see very late patients and felt frustrated when decisions that changed the flow were made by the physician or front desk staff without including the MA. MAs were also able to articulate how they managed competing priorities within the clinic, such as when a patient- or physician-driven need to extend appointments was at odds with maintaining a timely schedule. They were eager to share personal tips for time management and prided themselves on careful and accurate performance and skills they had learned on the job. MAs also described how efficiency could be adversely affected by the behaviors or attitudes of physicians. (See TABLE 2.)

Clinic environment

Thirty-six MAs (59%) reported that other MAs on their team were willing to help them out in clinic “a great deal” or “a lot” of the time, by helping to room a patient, acting as a chaperone for an exam, or doing a point-of-care lab. This sense of support varied across clinics (38% to 91% reported good support), suggesting that cultures vary by site. Some MAs expressed frustration at peers they saw as resistant to helping, exemplified by this verbatim quote from an interview:

“Some don’t want to help out. They may sigh. It’s how they react—you just know.” (Clinic #1, MA #2 interview)

Efficient MAs stressed the need for situational awareness to recognize when co-workers need help:

“[Peers often] are not aware that another MA is drowning. There’s 5 people who could have done that, and here I am running around and nobody budged.” (Clinic #5, MA #2 interview)

A minority of staff used the open-ended survey sections to describe clinic hierarchy. When asked about “pet peeves,” a few advised that physicians should not “talk down” to staff and should try to teach rather than criticize. Another asked that physicians not “bark orders” or have “low gratitude” for staff work. MAs found micromanaging stressful—particularly when the physician prompted the MA about patient arrivals:

“[I don’t like] when providers will make a comment about a patient arriving when you already know this information. You then rush to put [the] patient in [a] room, then [the] provider ends up making [the] patient wait an extensive amount of time. I’m perfectly capable of knowing when a patient arrives.” (Clinic #6, survey)
 

MAs did not like physicians “talking bad about us” or blaming the MA if the clinic is running behind.
 

Despite these concerns, most MAs reported feeling appreciated for the job they do. Only 10 (16%) reported that the people they work with rarely say “thank you,” and 2 (3%) stated they were not well supported by the physicians in clinic. Most (n = 38; 62%) strongly agreed or agreed that they felt part of the team and that their opinions matter. In the interviews, many expanded on this idea:

“I really feel like I’m valued, so I want to do everything I can to make [my doctor’s] day go better. If you want a good clinic, the best thing a doc can do is make the MA feel valued.” (Clinic #1, MA #1 interview)

Continue to: DISCUSSION...

DISCUSSION

Participants described their role much as an orchestra director, with MAs as the key to clinic flow and timeliness.⁹ Respondents articulated multiple common strategies used to increase their own efficiency and clinic flow; these may be considered best practices and incorporated as part of the basic training. Most MAs reported their day-to-day jobs were stressful and believed this was underrecognized, so efficiency strategies are critical. With staff completing multiple time-sensitive tasks during clinic, consistent co-worker support is crucial and may impact efficiency.⁸ Proper training of managers to provide that support and ensure equitable workloads may be one strategy to ensure that staff members feel the workplace is fair and collegial.

Several comments reflected the power differential within medical offices. One study reported that MAs and physicians “occupy roles at opposite ends of social and occupational hierarchies.”¹¹ It’s important for physicians to be cognizant of these patterns and clinic culture, as reducing a hierarchy-based environment will be appreciated by MAs.⁹ Prior research has found that MAs have higher perceptions of their own competence than do the physicians working with them.¹² If there is a fundamental lack of trust between the 2 groups, this will undoubtedly hinder team-building. Attention to this issue is key to a more favorable work environment.

Almost all respondents reported health care was a “calling,” which mirrors physician research that suggests seeing work as a “calling” is protective against burnout.^13,14 Open-ended comments indicated great pride in contributions, and most staff members felt appreciated by their teams. Many described the working relationships with physicians as critical to their satisfaction at work and indicated that strong partnerships motivated them to do their best to make the physician’s day easier. Staff job satisfaction is linked to improved quality of care, so treating staff well contributes to high-value care for patients.¹⁵ We also uncovered some MA “pet peeves” that hinder efficiency and could be shared with physicians to emphasize the importance of patience and civility.

One barrier to expansion of MA roles within PCMH practices is the limited pay and career ladder for MAs who adopt new job responsibilities that require advanced skills or training.^1,2 The mean MA salary at our institution ($37,372) is higher than in our state overall ($33,760), which may impact satisfaction.¹⁶ In addition, 93% of MAs are women; thus, they may continue to struggle more with lower pay than do workers in male- dominated professions.^17,18 Expected job growth from 2018-2028 is predicted at 23%, which may help to boost salaries. ¹⁹  Prior studies describe the lack of a job ladder or promotion opportunities as a challenge^1,20; this was not formally assessed in our study.


Prior research has found that MAs have higher perceptions of their own competence than do the physicians working with them.

MAs see work in family medicine as much harder than it is in other   specialty clinics. Being trusted with more responsibility, greater autonomy,^21-23 and expanded patient care roles can boost MA self-efficacy, which can reduce burnout for both physicians and MAs. ^8,24  However, new responsibilities should include appropriate training, support, and compensation, and match staff interests.⁷

Study limitations. The study was limited to 6 clinics in 1 department at a large academic medical center. Interviewed participants were selected by convenience and snowball sampling and thus, the results cannot be generalized to the population of MAs as a whole. As the initial interview goal was simply to gather efficiency tips, the project was not designed to be formal qualitative research. However, the discussions built on open-ended comments from the written survey helped contextualize our quantitative findings about efficiency. Notes were documented in real time by a single interviewer with rapid typing skills, which allowed capture of quotes verbatim. Subsequent studies would benefit from more formal qualitative research methods (recording and transcribing interviews, multiple coders to reduce risk of bias, and more complex thematic analysis).

Our research demonstrated how MAs perceive their roles in primary care and the facilitators and barriers to high efficiency in the workplace, which begins to fill an important knowledge gap in primary care. Disseminating practices that staff members themselves have identified as effective, and being attentive to how staff members are treated, may increase individual efficiency while improving staff retention and satisfaction.

We all have friends or relatives who, somehow, have managed to avoid catching COVID-19, which has infected more than 91.5 million Americans. You may even be one of the lucky ones yourself.

But health experts are saying: Not so fast. A mounting pile of scientific evidence suggests millions of Americans have been infected with the virus without ever even knowing it because they didn’t have symptoms or had mild cases they mistook for a cold or allergies.

The upshot: These silent COVID-19 cases reflect a hidden side of the pandemic that may be helping to drive new surges and viral variants.

Still, infectious disease experts say there is little doubt that some people have indeed managed to avoid COVID-19 infection altogether, and they are trying to understand why.

Several recent studies have suggested certain genetic and immune system traits may better protect this group of people against the coronavirus, making them less likely than others to be infected or seriously sickened. Researchers around the world are now studying these seemingly super-immune people for clues to what makes them so special, with an eye toward better vaccines, treatments, and prevention strategies.

Infectious disease specialists say both types of cases – those unknowingly infected by COVID-19 and people who’ve avoided the virus altogether – matter greatly to public health, more than 2 years into the pandemic.

“It’s definitely true that some people have had COVID and don’t realize it,” says Stephen Kissler, PhD, an infectious disease researcher with the Harvard T.H. Chan School of Public Health, Boston. “It is potentially good news if there’s more immunity in the population than we realize.”

But he says that being able to identify genetic and other factors that may offer some people protection against COVID-19 is an “exciting prospect” that could help find out who’s most at risk and improve efforts to get the pandemic under control.

Some studies have found a person’s genetic profile, past exposure to other COVID-like viruses, allergies, and even drugs they take for other conditions may all provide some defense – even for people who have not been vaccinated, don’t use masks, or don’t practice social distancing.

A person’s medical history and genetics may help decide their risk from new diseases, meaning “we may be able to help identify people who are at especially high risk from infection,” Dr. Kissler says. “That knowledge could help those people better shield themselves from infection and get quicker access to treatment and vaccines, if necessary. … We don’t yet know, but studies are ongoing for these things.”

Amesh Adalja, MD, an infectious disease specialist with the Johns Hopkins Center for Health Security, Baltimore, agrees that emerging research on people who’ve avoided infection offers the chance of new public health strategies to combat COVID-19.

“I’m sure there is some subset of people who are [COVID] negative,” he says. “So what explains that phenomenon, especially if that person was out there getting significant exposures?”
 

Have you had COVID without knowing it?

In a media briefing late last month, White House COVID-19 Response Coordinator Ashish Jha, MD, said more than 70% of the U.S. population has had the virus, according to the latest CDC data. That’s up from 33.5% in December.

But the actual number of people in the U.S. who have been infected with SARS-CoV-2, the scientific name for the virus that causes COVID-19, is likely to be much higher due to cases without symptoms that are unreported, experts say.

Since the early days of the pandemic, researchers have tried to put a number on these hidden cases, but that figure has been evolving and a clear consensus has not emerged.

In September 2020, a study published in the Annals of Internal Medicine said “approximately 40% to 45% of those infected with SARS-CoV-2 will remain asymptomatic.”

A follow-up analysis of 95 studies, published last December, reached similar findings, estimating that more than 40% of COVID-19 infections didn’t come with symptoms.

To get a better handle on the issue, CDC officials have been working with the American Red Cross and other blood banks to track COVID-19 antibodies – proteins your body makes after exposure to the virus to fight off an infection – in donors who said they have never had COVID-19.

While that joint effort is still ongoing, early findings say the number of donors with antibodies from COVID-19 infection increased in blood donors from 3.5% in July 2020 to at least 20.2% in May 2021. Since then, those percentages have soared, in part due to the introduction of vaccines, which also make the body produce COVID-19 antibodies.

The most current findings show that 83.3% of donors have combined COVID infection– and vaccine-induced antibodies in their blood. Those findings are based on 1.4 million blood donations.

Health experts say all of these studies are strong evidence that many COVID-19 cases continue to go undetected. In fact, the University of Washington Institute for Health Metrics and Evaluation estimates that only 7% of positive COVID-19 cases in the U.S. are being detected. That means case rates are actually 14.5 times higher than the official count of 131,000 new COVID infections each day, according to the Centers for Disease Control and Prevention, which reports the virus is still killing about 440 Americans daily.

So, why is all this important, in terms of public health?

Experts say people are more likely to be cautious if they know COVID-19 cases are high where they live, work, and play. On the other hand, if they believe case rates in their communities are lower than they actually are, they may be less likely to get vaccinated and boosted, wear masks indoors, avoid crowded indoor spaces, and take other precautions to fend off infection.
 

How do some avoid infection altogether?

In addition to tracking cases that go unreported and don’t have symptoms, infectious disease experts have also been trying to figure out why some people have managed to avoid getting the highly contagious virus.

Several leading lines of research have produced promising early results – suggesting that a person’s genetic makeup, past exposure to less-lethal coronaviruses, allergies, and even certain drugs they take for other conditions may all provide at least some protection against COVID.

“Our study showed that there are many human genes – hundreds of genes – that can impact SARS-CoV-2 infection,” says Neville Sanjana, PhD, a geneticist at New York University and the New York Genome Center who co-led the study. “With a better understanding of host genetic factors, we can find new kinds of therapies that target these host factors to block infection.”

In addition, he says several studies show some drugs that regulate genes, such as the breast cancer drug tamoxifen, also appear to knock down COVID-19 risk. He suggests such drugs, already approved by the Food and Drug Administration, might be “repurposed” to target the virus.

Studies in other countries show that patients taking tamoxifen before the pandemic were protected against severe COVID-19, Dr. Sanjana says. “That was a really cool thing, highlighting the power of harnessing host genetics. The virus critically depends on our genes to complete key parts of its life cycle.”

The NYU research findings echo other studies that have been published in recent months.

In July, a team of researchers led by the National Cancer Institute identified a genetic factor that appears to determine how severe an infection will be. In a study involving 3,000 people, they found that two gene changes, or mutations, that decrease the expression of a gene called OAS1 boosted the risk of hospitalization from COVID-19. OAS1 is part of the immune system’s response to viral infections.

As a result, developing a genetic therapy designed to increase the OAS1 gene’s expression might reduce the risk of severe disease.

“It’s very natural to get infected once you are exposed. There’s no magic bullet for that. But after you get infected, how you’re going to respond to this infection, that’s what is going to be affected by your genetic variants,” said Ludmila Prokunina-Olsson, PhD, the study’s lead researcher and chief of the National Cancer Institute’s Laboratory of Translational Genomics, Bethesda, Md., in an interview with NBC News.

Benjamin tenOever, PhD, a New York University virologist who co-authored the 2020 research, says the new genetic research is promising, but he believes it’s unlikely scientists will be able to identify a single gene responsible for actually preventing a COVID-19 infection.

“On the flip side, we have identified many genes that makes the disease worse,” he says.
 

T cells ‘remember’ past viral infections

As Dr. tenOever and Dr. Sanjana suggest, another intriguing line of research has found that prior viral infections may prime the body’s immune system to fight COVID-19.

Four other common coronaviruses – aside from SARS-CoV-2 – infect people worldwide, typically causing mild to moderate upper respiratory illnesses like the common cold, says Alessandro Sette, PhD, an infectious disease expert and vaccine researcher with the La Jolla (Calif.) Institute for Immunology.

In a recent study published in Science, he and his team found past infection with these other coronaviruses may give some protection against SARS-CoV-2.

T cells – white blood cells that act like immunological ninjas to ferret out and fight infections – appear to maintain a kind of “biological memory” of coronaviruses they have seen before and can mount an attack on similar pathogens, such SARS-CoV-2, Dr. Sette says.

The new work builds on a prior research he helped lead that found 40%-60% of people never exposed to SARS-CoV-2 had T cells that reacted to the virus – with their immune systems recognizing fragments of a virus they had never seen before.

Dr. Sette says his research shows that people whose T cells have this “preexisting memory” of past coronavirus exposures also tend to respond better to vaccination for reasons not yet well understood.

“The question is, at which point will there be enough immunity from vaccination, repeated infections from other coronaviruses, but also some of the variants of the SARS-CoV-2 … where infections become less frequent? We’re not there yet,” he says.

In addition to these exciting genetic and T-cell findings, other research has suggested low-grade inflammation from allergies – a key part of the body’s immune response to foreign substances – may also give some people an extra leg up, in terms of avoiding COVID infection.

Last May, a study of 1,400 households published in The Journal of Allergy and Clinical Immunology found that having a food allergy cut the risk of COVID-19 infection in half.

The researchers said it’s unclear why allergies may reduce the risk of infection, but they noted that people with food allergies express fewer ACE2 receptors on the surface of their airway cells, making it harder for the virus to enter cells.
 

The big picture: Prevention still your best bet

So, what’s the takeaway from all of this emerging research?

New York University’s Dr. tenOever says that while genes, T cells and allergies may offer some protection against COVID, tried-and-true precautions – vaccination, wearing masks, avoiding crowded indoor spaces, and social distancing – are likely to provide a greater defense.

He believes these precautions are likely why he and his family have never contracted COVID-19.

“I was tested weekly, as were my kids at school,” he says. “We definitely never got COVID, despite the fact that we live in New York City and I worked in a hospital every single day of the pandemic.”

Ziyad Al-Aly, MD, an infectious disease specialist and director of clinical epidemiology at Washington University in St. Louis, agrees that the new research on COVID-19 is intriguing but won’t likely result in practical changes in the approach to fighting the virus in the near term.

“Getting a deeper understanding of potential genetic factors or other characteristics – that could really help us understand why the virus just comes and goes without any ill effects in some people, and in other people it produces really serious disease,” he says. “That will really help us eventually to design better vaccines to prevent it or reduce severity or even [treat] people who get severe disease.”

In the meantime, Dr. Al-Aly says, “it’s still best to do everything you can to avoid infection in the first place – even if you’re vaccinated or previously infected, you should really try to avoid reinfection.”

That means sit outside if you can when visiting a restaurant. Wear a mask on a plane, even though it’s not required. And get vaccinated and boosted.

“In the future, there may be more tools to address this pandemic, but that’s really the best advice for now,” Dr. Al-Aly says.

We all have friends or relatives who, somehow, have managed to avoid catching COVID-19, which has infected more than 91.5 million Americans. You may even be one of the lucky ones yourself.

But health experts are saying: Not so fast. A mounting pile of scientific evidence suggests millions of Americans have been infected with the virus without ever even knowing it because they didn’t have symptoms or had mild cases they mistook for a cold or allergies.

The upshot: These silent COVID-19 cases reflect a hidden side of the pandemic that may be helping to drive new surges and viral variants.

Still, infectious disease experts say there is little doubt that some people have indeed managed to avoid COVID-19 infection altogether, and they are trying to understand why.

Several recent studies have suggested certain genetic and immune system traits may better protect this group of people against the coronavirus, making them less likely than others to be infected or seriously sickened. Researchers around the world are now studying these seemingly super-immune people for clues to what makes them so special, with an eye toward better vaccines, treatments, and prevention strategies.

Infectious disease specialists say both types of cases – those unknowingly infected by COVID-19 and people who’ve avoided the virus altogether – matter greatly to public health, more than 2 years into the pandemic.

“It’s definitely true that some people have had COVID and don’t realize it,” says Stephen Kissler, PhD, an infectious disease researcher with the Harvard T.H. Chan School of Public Health, Boston. “It is potentially good news if there’s more immunity in the population than we realize.”

But he says that being able to identify genetic and other factors that may offer some people protection against COVID-19 is an “exciting prospect” that could help find out who’s most at risk and improve efforts to get the pandemic under control.

Some studies have found a person’s genetic profile, past exposure to other COVID-like viruses, allergies, and even drugs they take for other conditions may all provide some defense – even for people who have not been vaccinated, don’t use masks, or don’t practice social distancing.

A person’s medical history and genetics may help decide their risk from new diseases, meaning “we may be able to help identify people who are at especially high risk from infection,” Dr. Kissler says. “That knowledge could help those people better shield themselves from infection and get quicker access to treatment and vaccines, if necessary. … We don’t yet know, but studies are ongoing for these things.”

Amesh Adalja, MD, an infectious disease specialist with the Johns Hopkins Center for Health Security, Baltimore, agrees that emerging research on people who’ve avoided infection offers the chance of new public health strategies to combat COVID-19.

“I’m sure there is some subset of people who are [COVID] negative,” he says. “So what explains that phenomenon, especially if that person was out there getting significant exposures?”
 

Have you had COVID without knowing it?

In a media briefing late last month, White House COVID-19 Response Coordinator Ashish Jha, MD, said more than 70% of the U.S. population has had the virus, according to the latest CDC data. That’s up from 33.5% in December.

But the actual number of people in the U.S. who have been infected with SARS-CoV-2, the scientific name for the virus that causes COVID-19, is likely to be much higher due to cases without symptoms that are unreported, experts say.

Since the early days of the pandemic, researchers have tried to put a number on these hidden cases, but that figure has been evolving and a clear consensus has not emerged.

In September 2020, a study published in the Annals of Internal Medicine said “approximately 40% to 45% of those infected with SARS-CoV-2 will remain asymptomatic.”
