Biden tests positive for COVID-19: White House
Biden, 79, is experiencing “very mild” symptoms, White House Press Secretary Karine Jean-Pierre said in a statement. The president is fully vaccinated and has been boosted twice and has started taking the antiviral Paxlovid since testing positive, Ms. Jean-Pierre said.
President Biden plans to isolate at the White House and “will continue to carry out all of his duties fully during that time,” the statement said.
“He has been in contact with members of the White House staff by phone this morning, and will participate in his planned meetings at the White House this morning via phone and Zoom from the residence.”
President Biden will return to in-person work after he tests negative.

Job market for physicians, advanced practitioners rebounds after COVID-19 slump: Report
After a year of uncertainty and decline because of the COVID-19 pandemic, according to a recently released report from Merritt Hawkins, the physician search division of AMN Healthcare.
The study is based on an analysis of job search and consulting assignments that the firm conducted on behalf of its health care organization clients from April 1, 2021, to March 31, 2022.
“Search engagements were down a little over 30% in 2020, but by the end of 2021, everything started spiking dramatically to the point of where we were at a 34-year high,” Michael Belkin, divisional vice president with Merritt Hawkins, told this news organization. “The pendulum has gone all the way back. People are more interested in going out and seeing their physicians.”
Demand for physicians was suppressed during the peak of the pandemic, as many hospitals curtailed elective procedures and many patients refrained from entering a medical facility. A large backlog of patients needing care subsequently developed.
This, combined with an aging population and widespread chronic medical conditions, has caused a strong surge in demand for physicians and advanced practitioners, according to the report.
In addition to the volume of searches increasing, physician starting salaries have rebounded from the COVID-19 downturn.
Average starting salaries of 14 physician specialties tracked in 2021/2022 increased, while only 3 decreased. Orthopedic surgeons were offered an average of $565,000 to start, exclusive of signing bonuses and other incentives, up from $546,000 the previous year. Urologists were offered an average of $510,000 to start, up from $497,000; gastroenterologists were offered $474,000, up from $453,000; while radiologists were offered $455,000, up from $401,000.
Similarly, a recent Medscape study based on responses from more than 13,000 U.S. physicians across 29 specialties found that income for all physician specialists increased, with otolaryngologists, gastroenterologists, and dermatologists experiencing the greatest gains.
A new reality
While the job market for physicians and advanced practitioners has seemingly recovered, there are many differences between today’s working environment for clinicians and what existed during the pandemic.
First, specialists are now stepping into the spotlight, a position that primary care clinicians previously held. The majority of Merritt Hawkins’ search engagements (64%) in 2021/2022 were for physician specialists, including cardiologists, gastroenterologists, orthopedic surgeons, neurologists, oncologists, and others. Only 17% of the search engagements were for primary care physicians, down from 18% in 2020/2021 and 20% in 2019/2020.
“We’ve seen specialties bounce back faster. Of course, you’ve got the aging population; you’ve got people that want that specialized care,” Mr. Belkin said.
Advanced practitioners also are playing a more significant role in the postpandemic word. In fact, 19% of Merritt Hawkins’ search engagements were for advanced practitioners, including nurse practitioners (NPs), physician assistants, and certified registered nurse anesthetists, up from 18% the previous year and just 13% the year prior to that, indicating growing demand for nonphysician providers.
NPs, in fact, topped the list of most requested search engagements, underscoring a shift from traditional physician office-based primary care delivery settings toward “convenient care” settings such as urgent care centers and retail clinics that are largely staffed by NPs and other advanced practitioners.
Advanced practitioners are taking on more responsibility for primary care simply because there is a large number of these professionals ready to take on the challenge.
The health care industry was “not able to produce enough primary care physicians over the last decade. So advanced practitioners, I believe, have slowly started to work alongside those primary care physicians. In a lot of areas such as your retail space, your CVS, your Walmart, your Walgreens, your standalone urgent cares, they’ve stepped up,” Mr. Belkin said.
Advanced practitioners also are providing the convenience that consumers are increasingly demanding.
“We are a society that wants things immediately ... but it’s still a challenge to schedule an appointment with a physician. However, it’s less of a challenge to get into a retail clinic or an urgent care center or to schedule something through telehealth,” Mr. Belkin noted.
More than just money
With the job market strong, the challenge for health care organizations is to create competitive recruiting packages. Sure enough, 92% of candidates were offered signing bonuses in 2021/2022 compared with just 61% in 2020/2021.
The financial incentives, however, might not be enough. In this environment, health care organizations need to go beyond simply offering competitive salaries to new recruits. For example, clinicians are seeking flexibility, as many potential hires are seeking remote positions. In fact, 18% of radiology search engagements were for teleradiologists, while 15% of its search engagements for psychiatrists were for telepsychiatrists in 2021/2022.
“Right now, quality of life is a very important factor. It’s work-life balance. It’s sensitivity to the stresses that we just experienced over the last 2.5 years,” Mr. Belkin concluded. “There’s more sensitivity around the culture of the organizations. What’s the leadership like? How did the organization handle the pandemic? How do they respond?”

What are your weaknesses?
In a video posted to TikTok by the comedian Will Flanary, MD, better known to his followers as Dr. Glaucomflecken, he imitates a neurosurgical residency interview. With glasses perched on the bridge of his nose, Dr. Glaucomflecken poses as the attending, asking: “What are your weaknesses?”
The residency applicant answers without hesitation: “My physiological need for sleep.” “What are your strengths?” The resident replies with the hard, steely stare of the determined and uninitiated: “My desire to eliminate my physiological need for sleep.”
If you follow Dr. Glaucomflecken on Twitter, you might know the skit I’m referencing. For many physicians and physicians-in-training, what makes the satire successful is its reflection of reality.
Many things have changed in medicine since his time, but the tired trope of the sleepless surgeon hangs on. Undaunted, I spent my second and third year of medical school accumulating accolades, conducting research, and connecting with mentors with the singular goal of joining the surgical ranks.
Midway through my third year, I completed a month-long surgical subinternship designed to give students a taste of what life would look like as an intern. I loved the operating room; it felt like the difference between being on dry land and being underwater. There were fewer distractions – your patient in the spotlight while everything else receded to the shadows.
However, as the month wore on, something stronger took hold. I couldn’t keep my eyes open in the darkened operating rooms and had to decline stools, fearing that I would fall asleep if I sat down.
On early morning prerounds, it’s 4:50 a.m. when I glance at the clock and pull back the curtain, already apologizing. My patient rolls over, flashing a wry smile. “Do you ever go home?” I’ve seen residents respond to this exact question in various ways. I live here. Yes. No. Soon. Not enough. My partner doesn’t think so.
There are days and, yes, years when we are led to believe this is what we live for: to be constantly available to our patients. It feels like a hollow victory when the patient, 2 days out from a total colectomy, begins to worry about your personal life. I ask her how she slept (not enough), any fevers (no), vomiting (no), urinating (I pause – she has a catheter).
My favorite part of these early morning rounds is the pause in my scripted litany of questions to listen to heart and lungs. It never fails to feel sacred: Patients become so quiet and still that I can’t help but think they have faith in me. Without prompting, she slides the back of her hospital gown forward like a curtain, already taking deep breaths so I can hear her lungs.
I look outside. The streetlights are still on, and from the seventh-floor window, I can watch staff making their way through the sliding double-doors, just beyond the yellowed pools of streetlight. I smile. I love medicine. I’m so tired.
For many in medicine, we are treated, and thus behave, as though our ability to manipulate physiology should also apply within the borders of our bodies: commanding less sleep, food, or bathroom breaks.
It places health care workers solidly in the realm of superhuman, living beyond one’s corporeal needs. The pandemic only heightened this misappropriation – adding hero and setting out a pedestal for health care workers to make their ungainly ascent. This kind of unsolicited admiration implicitly implies inhumanness, an otherness.
What would it look like if we started treating ourselves less like physicians and more like patients? I wish I was offering a solution, but really this is just a story.
To students rising through the ranks of medical training, identify what it is you need early and often. I can count on one hand how many physicians I’ve seen take a lunch break – even 10 minutes. Embrace hard work and self-preservation equally. My hope is that if enough of us take this path, it just might become a matter of course.

Charcoal could be the cure for the common high-fat diet
Charcoal won’t let high-fat diet weigh you down
Do you want to be the funniest person alive? Of course you do. It’s really simple too, just one joke can make you the greatest comedian of all time. All you have to do is go camping and cook food over a roaring campfire. When someone drops food into the fire (which they always will), get ready. Once they fish out the offending food, which is almost certainly coated in hot coals, tell them: “Ah, eat it anyway. A little texture never hurt!” Trust us, most hilarious and original gag of all time.
But before your hapless friend brushes off his hot dog and forces a laugh, consider this: Japanese researchers have found that a charcoal supplement can prevent weight gain in mice consuming a high-fat diet. Charcoal is actually quite the helpful substance, and not just for grilling. It’s been used as medicine for hundreds of years and even today is used as a treatment for drug overdose and excess gas and flatulence.
The study involved two groups of mice: One was fed a normal diet, the other a high-fat diet. After 12 weeks, the high-fat diet mice had gained weight. At that point, edible activated charcoal was added to their diet. From that point, weight gain was similar between the two groups, and the amount of bile acid, cholesterol, triglyceride, and fatty acid excreted by the high-fat mice increased by two to four times.
The researchers supported the notion that consuming an activated charcoal supplement before or while eating fatty food could prevent weight gain from said fatty food. Which works out well for the classic American barbecue, which is traditionally both high in fat and charcoal. All you have to do is buy some extra charcoal briquettes to pass around and munch on with your friends. Now that’s a party we can get behind.
There’s awake, and then there’s neurologically awake
Time to toss another urban legend onto the trash heap of history. Say goodbye to the benefits of uninterrupted sleep. It’s a fraud, a fake, a myth, a hit or myth, a swing and a myth, an old wives’ tale. You can stuff it and put it on a shelf next to Bigfoot, the Slender Man, and Twinkies.
We all thought we needed 8 hours of uninterrupted sleep every night, but guess who we forgot to tell? Our brains. They’ve been doing exactly the opposite all along, laughing at us the whole time. Smug SOBs.
To straighten out this mess, let’s bring in a scientist, Celia Kjaerby of the Center for Translational Neuromedicine at the University of Copenhagen: “You may think that sleep is a constant state that you are in, and then you wake up. But there is a lot more to sleep than meets the eye. We have learned that noradrenaline causes you to wake up more than 100 times a night. And that is during perfectly normal sleep.”
Those 100 or so sleep interruptions are so brief that we don’t even notice, but they are very important, according to a study conducted at the university. Those tiny little wake-up calls are “the essence for the part of sleep that makes us wake up rested and which enables us to remember what we learned the day before. ... The very short awakenings are created by waves of norepinephrine [and they] reset the brain so that it is ready to store memory when you dive back into sleep,” lead author Maiken Nedergaard, MD, explained.
The investigators compared the level of noradrenaline in sleeping mice with their electrical activity and found that the hormone constantly increased and decreased in a wavelike pattern. A high level meant that the animal was neurologically awake. Deeper valleys between the high points meant better sleep, and the mice with the “highest number of deep noradrenaline valleys were also the ones with the best memory,” the team said in their written statement.
Not just the best memory, they said, but “super memory.” That, of course, was enough to get the attention of Marvel Comics, so the next Disney superhero blockbuster will feature Nocturna, the queen of the night. Her power? Never forgets. Her archnemesis? The Insomniac. Her catchphrase? “Let me sleep on it.”
Words can hurt, literally
Growing up, we’re sure you heard the “sticks and stones” rhyme. Maybe you’ve even recited it once or twice to defend yourself. Well, forget it, because words can hurt and your brain knows it.
In a new study published in Frontiers in Communication, Marijn Struiksma, PhD, of Utrecht University, and colleagues incorporated the use of electroencephalography (EEG) and skin conductance on 79 women to see how words (specifically insults) actually affect the human body.
Each subject was asked to read three different types of statements: an insult, a compliment, and something factual but neutral. Half of the statements contained the subject’s name and half used somebody else’s. The participants were told that these statements were collected from three men.
Nobody interacted with each other, and the setting was completely clinical, yet the results were unmistakable. The EEG showed an effect in P2 amplitude with repetitive insults, no matter who it was about. Even though the insults weren’t real and the participants were aware of it, the brain still recognized them as hurtful, coming across as “mini slaps in the face,” Dr. Struiksma noted in a written statement.
The researchers noted that more needs to be done to better understand the long-term effects that insults can have and create a deeper understanding between words and emotion, but studying the effects of insults in a real-life setting is ethically tricky. This study is a start.
So, yeah, sticks and stones can break your bones, but words will actually hurt you.

Charcoal won’t let high-fat diet weigh you down
Do you want to be the funniest person alive? Of course you do. It’s really simple too, just one joke can make you the greatest comedian of all time. All you have to do is go camping and cook food over a roaring campfire. When someone drops food into the fire (which they always will), get ready. Once they fish out the offending food, which is almost certainly coated in hot coals, tell them: “Ah, eat it anyway. A little texture never hurt!” Trust us, most hilarious and original gag of all time.
But before your hapless friend brushes off his hot dog and forces a laugh, consider this: Japanese researchers have found that a charcoal supplement can prevent weight gain in mice consuming a high-fat diet. Charcoal is actually quite the helpful substance, and not just for grilling. It’s been used as medicine for hundreds of years and even today is used as a treatment for drug overdose and excess gas and flatulence.
The study involved two groups of mice: One was fed a normal diet, the other a high-fat diet. After 12 weeks, the high-fat diet mice had gained weight. At that point, edible activated charcoal was added to their diet. From that point, weight gain was similar between the two groups, and the amount of bile acid, cholesterol, triglyceride, and fatty acid excreted by the high-fat mice increased by two to four times.
The researchers supported the notion that consuming an activated charcoal supplement before or while eating fatty food could prevent weight gain from said fatty food. Which works out well for the classic American barbecue, which is traditionally both high in fat and charcoal. All you have to do is buy some extra charcoal briquettes to pass around and munch on with your friends. Now that’s a party we can get behind.
There’s awake, and then there’s neurologically awake
Time to toss another urban legend onto the trash heap of history. Say goodbye to the benefits of uninterrupted sleep. It’s a fraud, a fake, a myth, a hit or myth, a swing and a myth, an old wives’ tale. You can stuff it and put it on a shelf next to Bigfoot, the Slender Man, and Twinkies.
We all thought we needed 8 hours of uninterrupted sleep every night, but guess who we forgot to tell? Our brains. They’ve been doing exactly the opposite all along, laughing at us the whole time. Smug SOBs.
To straighten out this mess, let’s bring in a scientist, Celia Kjaerby of the Center for Translational Neuromedicine at the University of Copenhagen: “You may think that sleep is a constant state that you are in, and then you wake up. But there is a lot more to sleep than meets the eye. We have learned that noradrenaline causes you to wake up more than 100 times a night. And that is during perfectly normal sleep.”
Those 100 or so sleep interruptions are so brief that we don’t even notice, but they are very important, according to a study conducted at the university. Those tiny little wake-up calls are “the essence for the part of sleep that makes us wake up rested and which enables us to remember what we learned the day before. ... The very short awakenings are created by waves of norepinephrine [and they] reset the brain so that it is ready to store memory when you dive back into sleep,” lead author Maiken Nedergaard, MD, explained.
The investigators compared the level of noradrenaline in sleeping mice with their electrical activity and found that the hormone constantly increased and decreased in a wavelike pattern. A high level meant that the animal was neurologically awake.

Parkinson’s disease: Is copper culpable?
, according to investigators. The techniques used in this research also may enable rapid identification of blood-borne cofactors driving abnormal protein development in a range of other neurodegenerative diseases, reported lead author Olena Synhaivska, MSc, of the Swiss Federal Laboratories for Materials Science and Technology, Dübendorf, Switzerland.
“While alpha‑synuclein oligomers are the known neurotoxic species in Parkinson’s disease, the development of effective anti–Parkinson’s disease drugs requires targeting of specific structures arising in the early stages of alpha‑synuclein phase transitions or the nucleation-dependent elongation of oligomers into protofibrils,” the investigators wrote in ACS Chemical Neuroscience. “In parallel, advanced methods are required to routinely characterize the size and morphology of intermediary nano- and microstructures formed during self-assembly and aggregation in the presence of aqueous metal ions to track disease progression in, for example, a blood test, to provide effective personalized patient care.”
Pathologic aggregation of alpha‑synuclein
To better understand the relationship between copper and alpha‑synuclein, the investigators used liquid-based atomic force microscopy to observe the protein in solution over 10 days as it transitioned from a simple monomer to a complex, three-dimensional aggregate. Protein aggregation occurred in the absence or presence of copper; however, when incubated in solution with Cu2+ ions, alpha‑synuclein aggregated faster, predominantly forming annular (ring-shaped) structures that were not observed in the absence of copper.
These annular oligomers are noteworthy because they are cytotoxic, and they nucleate formation of alpha‑synuclein filaments, meaning they could serve as early therapeutic targets, according to the investigators.
The above experiments were supported by Raman spectroscopy, which confirmed the various superstructures of alpha‑synuclein formed with or without copper. In addition, the investigators used molecular dynamics computer simulations to map “the dimensions, supramolecular packing interactions, and thermodynamic stabilities” involved in aggregation.
These findings “could potentially serve as guidelines for better understanding protein aggregated states in body fluids from individuals who have been exposed to environmental metals over their lifetime,” the investigators wrote. “The nanoscale imaging, chemical spectroscopy, and integrated modeling-measurement methodologies presented here may inform rapid screening of other potential blood-borne cofactors, for example, other biometals, heavy metals, physiological amino acids, and metabolites, in directing and potentially rerouting intrinsically disordered protein aggregation in the initiation and pathology of neurodegenerative diseases.”
What is copper’s role in Parkinson’s disease pathogenesis?
In a joint written comment, Vikram Khurana MD, PhD, and Richard Krolewski MD, PhD, of Brigham and Women’s Hospital and Harvard Medical School, Boston, said, “This study is important in that it demonstrates that the presence of copper can accelerate and alter the aggregation of wild type alpha‑synuclein. We know that pathologic aggregation of alpha‑synuclein is critical for diseases like Parkinson’s disease known as synucleinopathies – so any insight into how this is happening at the biophysical level has potential implications for altering that process.”
While Dr. Khurana and Dr. Krolewski praised the elegance of the study, including the techniques used to observe alpha‑synuclein aggregation in near real-time, they suggested that more work is needed to determine relevance for patients with Parkinson’s disease.
“It is not clear whether this process is happening in cells, how alpha‑synuclein fibrils might be directly exposed to copper intracellularly (with most of the copper being bound to proteins), and the relevance of the copper concentrations used here are in question,” they said. “Substantially more cell biology and in vivo modeling would be needed to further evaluate the connection of copper specifically to synucleinopathy. All this notwithstanding, the findings are exciting and intriguing and definitely warrant follow-up.”
In the meantime, an increasing number of studies, including a recent preprint by Dr. Khurana and Dr. Krolewski, are strengthening the case for a link between copper exposure and Parkinson’s disease pathogenesis. This body of evidence, they noted, “now spans epidemiology, cell biology, and biophysics.”
Their study, which tested 53 pesticides associated with Parkinson’s disease in patient-derived pluripotent stem cells, found that 2 out of 10 pesticides causing cell death were copper compounds.
“Ongoing work will explore the mechanism of this cell death and investigate ways to mitigate it,” said Dr. Khurana and Dr. Krolewski. “Our hope is that this line of research will raise public awareness about these and other pesticides to reduce potential harm from their use and highlight protective approaches. The study by Dr. Synhaivska and colleagues now raises the possibility of new mechanisms.”
The study by Dr. Synhaivska and colleagues was supported by grants from the Swiss National Science Foundation and the Science Foundation Ireland. The investigators disclosed no conflicts of interest. Dr. Krolewski has been retained as an expert consultant for plaintiffs in a lawsuit on the role of pesticides in Parkinson’s disease causation.

Safest, most effective medications for spine-related pain in older adults?
, a new comprehensive literature review suggests.
Investigators assessed the evidence for medications used for this indication in older adults by reviewing 138 double-blind, placebo-controlled trials.
Among their key findings and recommendations: Acetaminophen has a favorable safety profile for spine-related pain but nonsteroidal anti-inflammatory drugs (NSAIDs) have greater efficacy.
However, NSAIDs should be used in lower doses in the short term, with gastrointestinal precaution, the researchers note.
Corticosteroids have the least evidence for treating nonspecific back pain, they add.
“Most older people experience neck or low back pain at some point, bothersome enough to see their doctor,” coinvestigator Michael Perloff, MD, PhD, department of neurology, Boston University, said in a news release.
“Our findings provide a helpful medication guide for physicians to use for spine pain in an older population that can have a complex medical history,” Dr. Perloff added.
The results were published online in Drugs and Aging.
Recommendations, warnings
With the graying of the U.S. population, spine-related pain is increasingly common, the investigators note.
Medications play an important role in pain management, but their use has limitations in the elderly, owing to reduced liver and renal function, comorbid medical problems, and polypharmacy.
Other key findings from the literature review include that, although the nerve pain medications gabapentin and pregabalin may cause dizziness or difficulty walking, they also have some demonstrated benefit for neck and back nerve pain, such as sciatica, in older adults.
These agents should be used in lower doses with smaller dose adjustments, the researchers note.
They caution that the muscle relaxants carisoprodol, chlorzoxazone, cyclobenzaprine, metaxalone, methocarbamol, and orphenadrine should be avoided in older adults because of their association with risk for sedation and falls.
‘Rational therapeutic choices’
Three other muscle relaxants – tizanidine, baclofen, and dantrolene – may be helpful for neck and back pain. The most evidence favors tizanidine and baclofen. These should be used in reduced doses. Tizanidine should be avoided in patients with liver disease, and for patients with kidney disease, the dosing of baclofen should be reduced, the investigators write.
Other findings include the following:
- Older tricyclic antidepressants should typically be avoided in this population because of their side effects, but nortriptyline and desipramine may be better tolerated for neck and back nerve pain at lower doses.
- Newer antidepressants, particularly the selective serotonin-norepinephrine reuptake inhibitor duloxetine, have a better safety profile and good efficacy for spine-related nerve pain.
- Traditional opioids are typically avoided in the treatment of spine-related pain in older adults, owing to their associated risks.
However, low-dose opioid therapy may be helpful for severe refractory pain, with close monitoring of patients, the researchers note.
Weaker opioids, such as tramadol, may be better tolerated by older patients. They work well when combined with acetaminophen, but they carry the risk for sedation, upset stomach, and constipation.
“Medications used at the correct dose, for the correct diagnosis, adjusting for preexisting medical problems can result in better use of treatments for spine pain,” coinvestigator Jonathan Fu, MD, also with the department of neurology, Boston University, said in the release.
“Rational therapeutic choices should be targeted to spine pain diagnosis, such as NSAIDs and acetaminophen for arthritic and myofascial-based complaints, gabapentinoids or duloxetine for neuropathic and radicular symptoms, antispastic agents for myofascial-based pain, and combination therapy for mixed etiologies,” the investigators write.
They also emphasize that medications should be coupled with physical therapy and exercise programs, as well as treatment of the underlying degenerative disease process and medical illness, while keeping in mind the need for possible interventions and/or corrective surgery.
The research had no specific funding. The investigators have reported no relevant financial relationships.

Investigators assessed the evidence for medications used for this indication in older adults by reviewing 138 double-blind, placebo-controlled trials.
Among their key findings and recommendations: Acetaminophen has a favorable safety profile for spine-related pain but nonsteroidal anti-inflammatory drugs (NSAIDs) have greater efficacy.
However, NSAIDs should be used in lower doses in the short term, with gastrointestinal precaution, the researchers note.
Corticosteroids have the least evidence for treating nonspecific back pain, they add.
“Most older people experience neck or low back pain at some point, bothersome enough to see their doctor,” coinvestigator Michael Perloff, MD, PhD, department of neurology, Boston University, said in a news release.
“Our findings provide a helpful medication guide for physicians to use for spine pain in an older population that can have a complex medical history,” Dr. Perloff added.
The results were published online in Drugs and Aging.
Recommendations, warnings
With the graying of the U.S. population, spine-related pain is increasingly common, the investigators note.
Medications play an important role in pain management, but their use has limitations in the elderly, owing to reduced liver and renal function, comorbid medical problems, and polypharmacy.
Other key findings from the literature review include that, although the nerve pain medications gabapentin and pregabalin may cause dizziness or difficulty walking, they also have some demonstrated benefit for neck and back nerve pain, such as sciatica, in older adults.
These agents should be used in lower doses with smaller dose adjustments, the researchers note.
They caution that the muscle relaxants carisoprodol, chlorzoxazone, cyclobenzaprine, metaxalone, methocarbamol, and orphenadrine should be avoided in older adults because of their association with risk for sedation and falls.
‘Rational therapeutic choices’
Three other muscle relaxants – tizanidine, baclofen, and dantrolene – may be helpful for neck and back pain. The most evidence favors tizanidine and baclofen. These should be used in reduced doses. Tizanidine should be avoided in patients with liver disease, and for patients with kidney disease, the dosing of baclofen should be reduced, the investigators write.
Other findings include the following:
- Older tricyclic antidepressants should typically be avoided in this population because of their side effects, but nortriptyline and desipramine may be better tolerated for neck and back nerve pain at lower doses.
- Newer antidepressants, particularly the selective serotonin-norepinephrine reuptake inhibitor duloxetine, have a better safety profile and good efficacy for spine-related nerve pain.
- Traditional opioids are typically avoided in the treatment of spine-related pain in older adults, owing to their associated risks.
However, low-dose opioid therapy may be helpful for severe refractory pain, with close monitoring of patients, the researchers note.
Weaker opioids, such as tramadol, may be better tolerated by older patients. They work well when combined with acetaminophen, but they carry the risk for sedation, upset stomach, and constipation.
“Medications used at the correct dose, for the correct diagnosis, adjusting for preexisting medical problems can result in better use of treatments for spine pain,” coinvestigator Jonathan Fu, MD, also with the department of neurology, Boston University, said in the release.
“Rational therapeutic choices should be targeted to spine pain diagnosis, such as NSAIDs and acetaminophen for arthritic and myofascial-based complaints, gabapentinoids or duloxetine for neuropathic and radicular symptoms, antispastic agents for myofascial-based pain, and combination therapy for mixed etiologies,” the investigators write.
They also emphasize that medications should be coupled with physical therapy and exercise programs, as well as treatment of the underlying degenerative disease process and medical illness, while keeping in mind the need for possible interventions and/or corrective surgery.
The research had no specific funding. The investigators have reported no relevant financial relationships.

The shell game
The shell game is probably the world’s oldest confidence game, going back 2,000-3,000 years. You still see people getting lured into it in cities today.
It’s also played, albeit legally, in physician offices and pharmacies around the country.
You know, the ones piled up in your sample cabinet. Get a month free of Whateveritscalled to try and/or have your copay reduced to $0 or something reasonably low. All, of course, subject to terms and conditions in the small print and that of your insurance carrier. Your mileage may vary.
In my experience these things often don’t work as well as advertised. Sometimes it’s because the patient doesn’t understand how to use them, other times because their pharmacy doesn’t want to have anything to do with the cards, and still other times because their insurance has some exclusion against them.
But they do sometimes work ... until they don’t. Sometimes, out of the blue, they’ll stop. Maybe there was an insurance change, or the pharmacy policy changed, or the manufacturer’s program changed, or the offer expired. I usually don’t know and rarely find out.
So the shell game begins. The patients call multiple pharmacies, trying to find one that may be able to honor the coupons. Then they call my office and ask me to switch the script. So I do. They they go to the pharmacy. Sometimes they can get the script, sometimes not. If not, they move to another pharmacy and call my office to switch it again. Wash, rinse, repeat.
Other times it’s more complicated. They want a new card for each try, so they show up at my office asking for one (usually they can be downloaded online so some try that. Others do both). Like pebbles under a shell, the prescriptions and cards get switched from pharmacy to pharmacy.
This isn’t exclusive to manufacturers’ copay cards. I see the same phenomenon with GoodRx and similar cost-saving programs. People move scripts around to find the best deal. It may be helping them, but it certainly doesn’t help me and my staff as we try to keep up, or the badly overworked pharmacy staff.
I’ve even had some patients take the audacious step of asking me to write a script in the name of their spouses so they can double their supply. Obviously, such requests are refused. I’m not going to play that game.
I understand new drugs are costly, and often outside the reach of many patients today. I know the manufacturers are trying to get their products tried, or even make them more affordable for those who need it.
But, in many cases, this becomes (unintentionally or intentionally; I’m not sure) a shell game. Legal, perhaps, but still equally frustrating for all of us who are trying to keep up with it.

Steroids no cure for obstructive sleep apnea in children
Children with obstructive sleep apnea syndrome (OSAS) who undergo treatment with intranasal corticosteroids (INCS) did not experience significant improvement in polysomnographic, neurobehavioral, and other symptoms at 3 and 12 months of treatment. At 12 months of INCS treatment, there was a statistically significant but not clinically relevant reduction in the obstructive apnea hypopnea index (OHAI).
“Previous studies were done in children with OSA with an obstructive apnea hypopnea index of less than 5, so they had very mild OSA,” Ignacio Tapia, MD, associate professor of pediatrics, University of Pennsylvania, Philadelphia, said in an interview.
“But then people started using the INCS for a whole range of OSA, so this is why we wanted to do the trial, to make sure that these drugs were being used correctly,” he added.
“The main message from this paper is that I think INCS may still have a role to play in OSA to treat some of the symptoms, like snoring, and in our study, quality of life indices also improved, ,” Dr. Tapia emphasized.
The study was published online in the journal Chest.
3 months of INCS
A total of 134 children between 5 and 12 years of age were randomly assigned to receive INCS for 3 months or placebo. Children in the original INCS arm were then reassigned to receive 9 more months of the same treatment or placebo. Symptoms as well as polysomnographic and neurobehavioral findings were measured at baseline, at 3 months, and again at 12 months.
“The primary outcome was OAHI change at 3 months, available for 122 children,” the authors explained. The OSAS was defined as an OAHI of between two and three events per hour. The median age of the children at baseline was 7.9 years, and the median OAHI baseline score was 5.8/hr (95% confidence interval, 3.6-9.7/hr). The total daily dose of the INCS used was 110 mcg.
At 3 months, the mean change in the OAHI from baseline was –1.73/hr (95% CI, –3.91 to 1.92/hr), while at 12 months, the mean change in the same index was –1.21 (–4.22 to 1.71/hr). These changes were not significantly different from OAHI changes observed among control participants. “OSAS symptoms and neurobehavioral results were not different [either] between the INCS and placebo groups at 3 and12 months,” the authors added.
However, among those children who received INCS treatment for the entire 12 months, the OAHI decreased significantly from 7.2/hr (95% CI, 3.62-9.88/hr) at baseline to 3.71/hr (95% CI, 1.56-6.4/hr; P = .039), although the OAHI did not normalize, the authors noted. Asked to clarify whether this change was not significant, Dr. Tapia said that it did meet statistical significance, but clinically, it meant that the children still needed some form of treatment, because they still had OSA in the range needing treatment.
The placebo group had more asthma exacerbations, upper respiratory tract infections, and exacerbations of OSAS symptoms, compared with children in the INCS group. It is possible that INCS provided a certain degree of protection from asthma exacerbation, the authors suggested.
However, recent guidelines from the American Academy of Pediatrics suggest that clinicians may prescribe these agents for children with mild OSAS in whom adenotonsillectomy is contraindicated; for those with mild postoperative OSAS, adenotonsillectomy remains the treatment of choice for childhood OSA. “The low level of enthusiasm for INCS in these guidelines is based on results from studies of INCS treatment of OSAS that had been limited by small sample size, lack of placebo control, limited duration, and variability in baseline data,” the authors wrote.
“The results of the current larger and more rigorous study of children with a wider range of OSAS also do not support the currently liberal use of INCS for the treatment of OSAS,” they wrote.
Complex issue
In a comment, Rakesh Bhattacharjee, MD, associate professor of pediatrics, University of California, San Diego, noted that he does prescribe INCS for children with mild OSA but not for all children. “We based our decisions on polysomnography, which we use to categorize OSA as mild, moderate, or severe.
“But we certainly do offer this treatment for children with mild sleep apnea as a way to avoid surgical treatment,” Dr. Bhattacharjee added. He also uses INCS for residual sleep apnea that some children experience following adenotonsillectomy. As the current study suggests, many people are treating sleep apnea empirically without confirming the severity of the disorder by a sleep study.
“If a sleep study is not done, we don’t know how severe it is, so this would advocate for the utility of a sleep study so that you can quantify the severity of symptoms and target your therapy to children who might be appropriate for INCS therapy,” Dr. Bhattacharjee said.
On the other hand, surgery is not always relevant even if a child has enlarged adenoids and tonsils, as, for example, a child with obesity. In these children, physicians need to think about other treatments, such as continuous positive airways pressure. “CPAP is not perfect,” Dr. Bhattacharjee observed. “And as pediatricians, we need to do a lot of work to improve the use of CPAP, but, that said, there are children for whom INCS and surgery might be a waste of time, and this is where CPAP might be an alternative.”
Dr. Bhattacharjee previously was the lead author of a large study of children who underwent treatment with CPAP. While findings suggested that adherence to treatment is lower in children than it is for adults, the authors also showed that numerous actionable factors could used to improve adherence to CPAP among children who might otherwise benefit from it.
The authors disclosed no relevant financial relationships. Dr. Bhattacharjee has served as a scientific adviser for Jazz Pharmaceuticals.

FROM CHEST
Alcohol’s detrimental impact on the brain explained?
Results of a large observational study suggest brain iron accumulation is a “plausible pathway” through which alcohol negatively affects cognition, study Anya Topiwala, MD, PhD, senior clinical researcher, Nuffield Department of Population Health, University of Oxford, England, said in an interview.
Study participants who drank 56 grams of alcohol a week had higher brain iron levels. The U.K. guideline for “low risk” alcohol consumption is less than 14 units weekly, or 112 grams.
“We are finding harmful associations with iron within those low-risk alcohol intake guidelines,” said Dr. Topiwala.
The study was published online in PLOS Medicine.
Early intervention opportunity?
Previous research suggests higher brain iron may be involved in the pathophysiology of Alzheimer’s and Parkinson’s diseases. However, it’s unclear whether deposition plays a role in alcohol’s effect on the brain and if it does, whether this could present an opportunity for early intervention with, for example, chelating agents.
The study included 20,729 participants in the UK Biobank study, which recruited volunteers from 2006 to 2010. Participants had a mean age of 54.8 years, and 48.6% were female.
Participants self-identified as current, never, or previous alcohol consumers. For current drinkers, researchers calculated the total weekly number of U.K. units of alcohol consumed. One unit is 8 grams. A standard drink in the United States is 14 grams. They categorized weekly consumption into quintiles and used the lowest quintile as the reference category.
Participants underwent MRI to determine brain iron levels. Areas of interest were deep brain structures in the basal ganglia.
Mean weekly alcohol consumption was 17.7 units, which is higher than U.K. guidelines for low-risk consumption. “Half of the sample were drinking above what is recommended,” said Dr. Topiwala.
Alcohol consumption was associated with markers of higher iron in the bilateral putamen (beta, 0.08 standard deviation; 95% confidence interval, 0.06-0.09; P < .001), caudate (beta, 0.05; 95% CI, 0.04-0.07; P < .001), and substantia nigra (beta, 0.03; 95% CI; 0.02-0.05; P < .001).
Poorer performance
Drinking more than 7 units (56 grams) weekly was associated with higher susceptibility for all brain regions, except the thalamus.
Controlling for menopause status did not alter associations between alcohol and susceptibility for any brain region. This was also the case when excluding blood pressure and cholesterol as covariates.
There were significant interactions with age in the bilateral putamen and caudate but not with sex, smoking, or Townsend Deprivation Index, which includes such factors as unemployment and living conditions.
To gather data on liver iron levels, participants underwent abdominal imaging at the same time as brain imaging. Dr. Topiwala explained that the liver is a primary storage center for iron, so it was used as “a kind of surrogate marker” of iron in the body.
The researchers showed an indirect effect of alcohol through systemic iron. A 1 SD increase in weekly alcohol consumption was associated with a 0.05 mg/g (95% CI, 0.02-0.07; P < .001) increase in liver iron. In addition, a 1 mg/g increase in liver iron was associated with a 0.44 (95% CI, 0.35-0.52; P < .001) SD increase in left putamen susceptibility.
In this sample, 32% (95% CI, 22-49; P < .001) of alcohol’s total effect on left putamen susceptibility was mediated via higher systemic iron levels.
To minimize the impact of other factors influencing the association between alcohol consumption and brain iron – and the possibility that people with more brain iron drink more – researchers used Mendelian randomization that considers genetically predicted alcohol intake. This analysis supported findings of associations between alcohol consumption and brain iron.
Participants completed a cognitive battery, which included trail-making tests that reflect executive function, puzzle tests that assess fluid intelligence or logic and reasoning, and task-based tests using the “Snap” card game to measure reaction time.
Investigators found the more iron that was present in certain brain regions, the poorer participants’ cognitive performance.
Patients should know about the risks of moderate alcohol intake so they can make decisions about drinking, said Dr. Topiwala. “They should be aware that 14 units of alcohol per week is not a zero risk.”
Novel research
Commenting for this news organization, Heather Snyder, PhD, vice president of medical and scientific relations, Alzheimer’s Association, noted the study’s large size as a strength of the research.
She noted previous research has shown an association between higher iron levels and alcohol dependence and worse cognitive function, but the potential connection of brain iron levels, moderate alcohol consumption, and cognition has not been studied to date.
“This paper aims to look at whether there is a potential biological link between moderate alcohol consumption and cognition through iron-related pathways.”
The authors suggest more work is needed to understand whether alcohol consumption impacts iron-related biologies to affect downstream cognition, said Dr. Snyder. “Although this study does not answer that question, it does highlight some important questions.”

Results of a large observational study suggest brain iron accumulation is a “plausible pathway” through which alcohol negatively affects cognition, study Anya Topiwala, MD, PhD, senior clinical researcher, Nuffield Department of Population Health, University of Oxford, England, said in an interview.
Study participants who drank 56 grams of alcohol a week had higher brain iron levels. The U.K. guideline for “low risk” alcohol consumption is less than 14 units weekly, or 112 grams.
“We are finding harmful associations with iron within those low-risk alcohol intake guidelines,” said Dr. Topiwala.
The study was published online in PLOS Medicine.
Early intervention opportunity?
Previous research suggests higher brain iron may be involved in the pathophysiology of Alzheimer’s and Parkinson’s diseases. However, it’s unclear whether deposition plays a role in alcohol’s effect on the brain and if it does, whether this could present an opportunity for early intervention with, for example, chelating agents.
The study included 20,729 participants in the UK Biobank study, which recruited volunteers from 2006 to 2010. Participants had a mean age of 54.8 years, and 48.6% were female.
Participants self-identified as current, never, or previous alcohol consumers. For current drinkers, researchers calculated the total weekly number of U.K. units of alcohol consumed. One unit is 8 grams. A standard drink in the United States is 14 grams. They categorized weekly consumption into quintiles and used the lowest quintile as the reference category.
Participants underwent MRI to determine brain iron levels. Areas of interest were deep brain structures in the basal ganglia.
Mean weekly alcohol consumption was 17.7 units, which is higher than U.K. guidelines for low-risk consumption. “Half of the sample were drinking above what is recommended,” said Dr. Topiwala.
Alcohol consumption was associated with markers of higher iron in the bilateral putamen (beta, 0.08 standard deviation; 95% confidence interval, 0.06-0.09; P < .001), caudate (beta, 0.05; 95% CI, 0.04-0.07; P < .001), and substantia nigra (beta, 0.03; 95% CI; 0.02-0.05; P < .001).
Poorer performance
Drinking more than 7 units (56 grams) weekly was associated with higher susceptibility for all brain regions, except the thalamus.
Controlling for menopause status did not alter associations between alcohol and susceptibility for any brain region. This was also the case when excluding blood pressure and cholesterol as covariates.
There were significant interactions with age in the bilateral putamen and caudate but not with sex, smoking, or Townsend Deprivation Index, which includes such factors as unemployment and living conditions.
To gather data on liver iron levels, participants underwent abdominal imaging at the same time as brain imaging. Dr. Topiwala explained that the liver is a primary storage center for iron, so it was used as “a kind of surrogate marker” of iron in the body.
The researchers showed an indirect effect of alcohol through systemic iron. A 1 SD increase in weekly alcohol consumption was associated with a 0.05 mg/g (95% CI, 0.02-0.07; P < .001) increase in liver iron. In addition, a 1 mg/g increase in liver iron was associated with a 0.44 (95% CI, 0.35-0.52; P < .001) SD increase in left putamen susceptibility.
In this sample, 32% (95% CI, 22-49; P < .001) of alcohol’s total effect on left putamen susceptibility was mediated via higher systemic iron levels.
To minimize the impact of other factors influencing the association between alcohol consumption and brain iron – and the possibility that people with more brain iron drink more – researchers used Mendelian randomization that considers genetically predicted alcohol intake. This analysis supported findings of associations between alcohol consumption and brain iron.
Participants completed a cognitive battery, which included trail-making tests that reflect executive function, puzzle tests that assess fluid intelligence or logic and reasoning, and task-based tests using the “Snap” card game to measure reaction time.
Investigators found the more iron that was present in certain brain regions, the poorer participants’ cognitive performance.
Patients should know about the risks of moderate alcohol intake so they can make decisions about drinking, said Dr. Topiwala. “They should be aware that 14 units of alcohol per week is not a zero risk.”

Best meds for insomnia identified?
In a comprehensive comparative-effectiveness analysis, lemborexant and eszopiclone showed the best efficacy, acceptability, and tolerability for acute and long-term insomnia treatment.
However, eszopiclone may cause substantial side effects – and safety data on lemborexant were inconclusive, the researchers note.
Not surprisingly, short-acting, intermediate-acting, and long-acting benzodiazepines were effective in the acute treatment of insomnia, but they have unfavorable tolerability and safety profiles, and there are no long-term data on these issues.
For many insomnia medications, there is a “striking” and “appalling” lack of long-term data, study investigator Andrea Cipriani, MD, PhD, professor of psychiatry, University of Oxford, United Kingdom, noted during a press briefing.
“This is a call for regulators to raise the bar and ask for long-term data when companies submit an application for licensing insomnia drugs,” Dr. Cipriani said.
The findings were published online in The Lancet.
Prevalent, debilitating
Insomnia is highly prevalent, affecting up to 1 in 5 adults, and can have a profound impact on health, well-being, and productivity.
Sleep hygiene and cognitive-behavioral therapy for insomnia (CBT-I) are recommended first-line treatments, but they are often unavailable, which often leads patients and clinicians to turn to medications.
However, “insomnia drugs are not all created equal. Even within the same drug class there are differences,” Dr. Cipriani said.
In a large-scale systematic review and network meta-analysis, the researchers analyzed data from 154 double-blind, randomized controlled trials of medications (licensed or not) used for acute and long-term treatment of insomnia in 44,089 adults (mean age, 51.7 years; 63% women).
Results showed, for the acute treatment of insomnia, benzodiazepines, doxylamine, eszopiclone, lemborexant, seltorexant, zolpidem, and zopiclone were more effective than placebo (standardized mean difference range, 0.36-0.83; high-to-moderate certainty of evidence).
In addition, benzodiazepines, eszopiclone, zolpidem, and zopiclone were more effective than melatonin, ramelteon, and zaleplon (SMD, 0.27-0.71; moderate-to-very low certainty of evidence).
“Our results show that the melatonergic drugs melatonin and ramelteon are not really effective. The data do not support the regular use of these drugs,” co-investigator Phil Cowen, PhD, professor of psychopharmacology, University of Oxford, said at the briefing.
Best available evidence
What little long-term data is available suggest eszopiclone and lemborexant are more effective than placebo. Plus, eszopiclone is more effective than ramelteon and zolpidem but with “very low” certainty of evidence, the researchers report.
“There was insufficient evidence to support the prescription of benzodiazepines and zolpidem in long-term treatment,” they write.
Another problem was lack of data on other important outcomes, they add.
“We wanted to look at hangover effects, daytime sleepiness, [and] rebound effect, but often there was no data reported in trials. We need to collect data about these outcomes because they matter to clinicians and patients,” Dr. Cipriani said.
Summing up, the researchers note the current findings represent the “best available evidence base to guide the choice about pharmacological treatment for insomnia disorder in adults and will assist in shared decisionmaking between patients, carers, and their clinicians, as well as policy makers.”
They caution, however, that all statements comparing the merits of one drug with another “should be tempered by the potential limitations of the current analysis, the quality of the available evidence, the characteristics of the patient populations, and the uncertainties that might result from choice of dose or treatment setting.”
In addition, it is important to also consider nonpharmacologic treatments for insomnia disorder, as they are supported by “high-quality evidence and recommended as first-line treatment by guidelines,” the investigator write.
Shared decisionmaking
In an accompanying editorial, Myrto Samara, MD, University of Thessaly, Larissa, Greece, agrees with the researchers that discussion with patients is key.
“For insomnia treatment, patient-physician shared decisionmaking is crucial to decide when a pharmacological intervention is deemed necessary and which drug [is] to be given by considering the trade-offs for efficacy and side effects,” Dr. Samara writes.
The study was funded by the UK National Institute for Health Research (NIHR) Oxford Health Biomedical Research Center. Dr. Cipriani has received research and consultancy fees from the Italian Network for Pediatric Trials, CARIPLO Foundation, and Angelini Pharma, and is the chief and principal investigator of two trials of seltorexant in depression that are sponsored by Janssen. Dr. Samara has reported no relevant financial relationships.
