Physicians and other clinicians could more easily exit contracts and change jobs under the Federal Trade Commission’s new proposed rule that would block companies from limiting employees’ ability to work for a rival.

The proposed rule seeks to ban companies from enforcing noncompete clauses in employment contracts, a practice that represents an “unfair method of competition” with “exploitative and widespread” impacts, including suppression of wages, innovation, and entrepreneurial spirit, the FTC said. The public has 60 days to submit comments on the proposal before the FTC issues the final rule.

Employers often include noncompete clauses in physician contracts because they want to avoid having patients leave their health care system and follow a doctor to a competitor. A 2018 survey of primary care physicians found that about half of office-based physicians and 37% of physicians employed at hospitals or freestanding care centers were bound by restrictive covenants.

“A federal ban on noncompete agreements will ensure that physicians nationwide can finally change jobs without fear of being sued,” Erik B. Smith, MD, JD, clinical assistant professor of anesthesiology at the University of Southern California, Los Angeles, said in an interview.

Many doctors would like to see noncompete agreements vanish, but some physicians still favor them.

“As a small-practice owner, I am personally against this. The noncompete helps me take a risk and hire a physician. It typically takes 2-3 years for me to break even. I think this will further consolidate employment with large hospital systems unfortunately,” Texas cardiologist Rishin Shah, MD, recently tweeted in response to the FTC announcement.

Dr. Smith, who has advocated for noncompete reform, said about half of states currently allow the controversial clauses.

However, several states have recently passed laws restricting their use. California, North Dakota, and Oklahoma ban noncompetes, although some narrowly defined exceptions, such as the sale of a business, remain.

Other states, like Colorado, Illinois, and Oregon, broadly ban noncompete clauses, except for workers earning above a certain threshold. For example, in Colorado, noncompete agreements are permitted for highly compensated employees earning more than $101,250.

Despite additional restrictions on noncompete agreements for workers in the District of Columbia, the new legislation does not apply to physicians earning total compensation of $250,000 or more. However, their employers must define the geographic parameters of the noncompete and limit postemployment restrictions to 2 years.

Restrictive covenants are “uniquely challenging to family medicine’s emphasis on longitudinal care and the patient-physician relationship,” said Tochi Iroku-Malize, MD, MPH, president of the American Academy of Family Physicians. The limitations imposed by noncompete agreements “potentially reduce patient choice, lower the quality of care for patients, and ultimately harm the foundation of family medicine – our relationships with our patients.”

Although the proposed rule aligns with President Biden’s executive order promoting economic competition, Dr. Smith said a national ban on noncompete agreements may push the limits of FTC authority.

“This new rule will certainly result in a ‘major questions doctrine’ Supreme Court challenge,” said Dr. Smith, and possibly be struck down if the court determines an administrative overstep into areas of “vast economic or political significance.”
 

A controversial policy

The American Medical Association’s code of ethics discourages covenants that “unreasonably restrict” the ability of physicians to practice following contract termination. And in 2022, the AMA cited “overly broad” noncompete language as a red flag young physicians should watch out for during contract negotiations.

But in 2020, the AMA asked the FTC not to use its rulemaking authority to regulate noncompete clauses in physician employment contracts, and instead, relegate enforcement of such agreements to each state. The American Hospital Association expressed similar views.

Still, the FTC said that eliminating noncompete clauses will increase annual wages by $300 billion, allow 30 million Americans to pursue better job opportunities, and encourage hiring competition among employers. It will also save consumers up to $148 billion in health care costs annually.

“Noncompetes block workers from freely switching jobs, depriving them of higher wages and better working conditions, and depriving businesses of a talent pool that they need to build and expand,” Lina M. Khan, FTC chair, said in a press release about the proposal.

A national ban on noncompetes would keep more physicians in the industry and practicing in their communities, a win for patients and providers, said Dr. Smith. It could also compel employers to offer more competitive employment packages, including fair wages, better work conditions, and a culture of well-being and patient safety.

“Whatever the final rule is, I’m certain it will be legally challenged,” said Dr. Smith, adding that the nation’s most prominent business lobbying group, the Chamber of Commerce, has already issued a statement calling the rule “blatantly unlawful."

When I was a resident (back in the Cretaceous era), the idea of autoimmune encephalitis was just beginning to take hold. It was kind of like Bigfoot. A few reports, vague articles, the occasional sighting of what may or may not be a case. …

Unlike Bigfoot, however, the evidence quickly added up until there was no question that such a disorder existed. Then disorder became disorders, and now it seems a few more types are added to the list each year.

This doesn’t change the fact that they’re still, in the grand scheme of general neurology, relatively rare, though no one questions that they exist.

Today people still wishfully take pictures of Bigfoot, but they turn out to be images of bears or other animals, or tricks of light and shadow.

This is an issue with human thought. Many times we see what we want to see, especially if it’s more interesting than a mundane alternative.

An autoimmune encephalitis article in the January 2023 issue of JAMA Neurology looked into this. On reviewing 393 patients diagnosed with the disorder, the researchers found that 27% of them actually didn’t have it at all. Such things as functional disorders, neurodegenerative diseases, and primary psychiatric diagnoses were, instead, the culprits.

I’m not criticizing those who made an incorrect diagnosis. We all do. That’s the nature of medicine.

Which is worse? Missing the diagnosis entirely and not treating, or diagnosing a patient with something else and treating incorrectly? I guess it depends on the disease and nature of treatment.

Certainly, finding a case of autoimmune encephalitis is more interesting than, say toxic-metabolic encephalopathy from a bladder infection, just as getting a picture of Bigfoot is way more cool than one of a bear with mange.

But we need to be careful when faced with equivocal labs and data lest we read too much into them. There are too many gray zones in medicine to lead you astray. Not to say we won’t be. Even well-intentioned physicians (which I assume is pretty much all of us) are going to make mistakes.

But it’s not just rare diseases. In the early 1990s two different studies found that 24% of patients diagnosed with Parkinson’s disease were found to have something else on autopsy.

That was 30 years ago. Now we have DaT scans to help. Maybe our abilities as neurologists have also gotten better (though I don’t think the neurological exam has changed much since Charcot).

Our gadgets, labs, and treatments get better every year. We have tools available to us now that were unthinkable a generation ago. For that matter, they were unthinkable when I began my career.

But they don’t change the fact that human error never goes away. All of us are susceptible to it, and all of us make mistakes.

Such is the way of medicine now, and likely always. All we can do is our best and keep moving forward.

Every year, during the relatively slow winter-months period, I like to take a tour of my office from the paradigm of a patient visiting our facility for the first time. When was the last time you did a comprehensive inspection, looking for problems that your patients might see?

We tend not to notice gradual deterioration in the workplace we inhabit every day: Carpets fade and dull with constant traffic and cleaning; wallpaper and paint accumulate dirt, stains, and damage; furniture gets dirty and dented, fabric rips, hardware goes missing; laminate peels off the edges of desks and cabinets.

When did you last take a good look at your waiting room? How clean is it? Patients expect cleanliness in doctor’s offices, and they expect the reception area to be neat. How are the carpeting and upholstery holding up? Sit in your chairs; how do they feel? Patients don’t appreciate a sore back or bottom from any chairs, especially in a medical office. Consider investing in new furniture that will be attractive and comfortable for your patients.

Look at the decor itself; is it dated or just plain “old-looking?” Any interior designer will tell you they can determine quite accurately when a space was last decorated, simply by the color and style of the materials used. If your office is stuck in the ‘90s, it’s probably time for a change. Even if you don’t find anything obvious, it’s wise to check periodically for subtle evidence of age: Find some patches of protected carpeting and flooring under stationary furniture and compare them to exposed floors.

If your color scheme is hopelessly out of date and style, or if you are just tired of it, change it. Wallpaper and carpeting should be long-wearing industrial quality; paint should be high-quality “eggshell” finish to facilitate cleaning, and everything should be professionally applied. (This is neither the time nor place for do-it-yourself experiments.) Consider updating your overhead lighting. The harsh glow of fluorescent lights amid an uninspired decor creates a sterile, uninviting atmosphere.

During renovation, get your building’s maintenance crew to fix any nagging plumbing, electrical, or heating/air conditioning problems while pipes, ducts, and wires are more readily accessible. This is also a good time to clear out old textbooks, journals, and files that you will never open again, in this digital age.

If your wall decorations are dated and unattractive, now would be a good time to replace at least some of them. This need not be an expensive proposition; a few years ago, I redecorated my exam room walls with framed photos from my travel adventures – to very positive responses from patients and staff alike. If you’re not an artist or photographer, invite a family member, or local artists or talented patients, to display some of their creations on your walls. If you get too many contributions, you can rotate them on a periodic basis.

Plants are great aesthetic accents, yet many offices have little or no plant life. Plants naturally aerate an office suite and help make it feel less stuffy. Also, multiple studies have found that plants promote productivity among office staff and create a sense of calm for apprehensive patients. Improvements like this can make a big difference. They show an attention to detail and a willingness to make your practice as inviting as possible for patients and employees alike.

Spruce-up time is also an excellent opportunity to inventory your medical equipment. We’ve all seen “vintage” offices full of gadgets that were state-of-the-art decades ago. Nostalgia is nice; but would you want to be treated by a physician whose office could be a Smithsonian exhibit titled, “Doctor’s Office Circa 1975?” Neither would your patients, for the most part; many – particularly younger ones – assume that doctors who don’t keep up with technological innovations don’t keep up with anything else, either.

If you’re planning a vacation this year (and I hope you are), that would be the perfect time for a re-do. Your patients will be spared the dust and turmoil, tradespeople won’t have to work around your office hours, and you won’t have to cancel any hours that weren’t already canceled. Best of all, you’ll come back to a clean, fresh environment.

Your patients will be spared the dust and turmoil, tradespeople won’t have to work around your office hours, and you won’t have to cancel any hours that weren’t already canceled. Best of all, you’ll come back to a clean, fresh environment.

People with higher dietary zinc intake have a nearly one-third lower risk of migraine than those who get little zinc in their diets, according to results from a cross-sectional study of more than 11,000 American adults.

For their research, published online in Headache, Huanxian Liu, MD, and colleagues at Chinese PLA General Hospital in Beijing, analyzed publicly available data from the U.S. National Health and Nutrition Examination Survey to determine whether people self-reporting migraine or severe headache saw lower zinc intake, compared with people without migraine. The data used in the analysis was collected between 1999 and 2004, and contained information on foods and drinks consumed by participants in a 24-hour period, along with additional health information.
 

An inverse relationship

The investigators divided their study’s 11,088 participants (mean age, 46.5 years; 50% female) into quintiles based on dietary zinc consumption as inferred from foods eaten. They also considered zinc supplementation, for which data was available for 4,324 participants, of whom 2,607 reported use of supplements containing zinc.

Some 20% of the cohort (n = 2,236) reported migraine or severe headache within the previous 3 months. Pregnant women were excluded from analysis, and the investigators adjusted for a range of covariates, including age, sex, ethnicity, education level, body mass, smoking, diabetes, cardiovascular disease, and nutritional factors.

Dr. Liu and colleagues reported an inverse association between dietary zinc consumption and migraine, with the highest-consuming quintile of the cohort (15.8 mg or more zinc per day) seeing lowest risk of migraine (odds ratio, 0.70; 95% confidence interval, 0.52-0.94; P = .029), compared with the low-consuming quintile (5.9 mg or less daily). Among people getting high levels of zinc (19.3-32.5 mg daily) through supplements, risk of migraine was lower still, to between an OR of 0.62 (95% CI: 0.46–0.83, P = 0.019) and an OR of 0.67 (95% CI, 0.49–0.91; P = .045).

While the investigators acknowledged limitations of the study, including its cross-sectional design and use of a broad question to discern prevalence of migraine, the findings suggest that “zinc is an important nutrient that influences migraine,” they wrote, citing evidence for its antioxidant and anti-inflammatory properties.
 

The importance of nutritional factors

Commenting on the research findings, Deborah I. Friedman, MD, MPH, a headache specialist in Dallas, said that Dr. Liu and colleagues’ findings added to a growing information base about nutritional factors and migraine. For example, “low magnesium levels are common in people with migraine, and magnesium supplementation is a recommended preventive treatment for migraine.”

Dr. Friedman cited a recent study showing that vitamin B₁₂ and magnesium supplementation in women (, combined with high-intensity interval training, “silenced” the inflammation signaling pathway, helped migraine pain and decreased levels of calcitonin gene-related peptide. A 2022 randomized trial found that alpha lipoic acid supplementation reduced migraine severity, frequency and disability in women with episodic migraine.

Vitamin D levels are also lower in people with migraine, compared with controls, Dr. Friedman noted, and a randomized trial of 2,000 IU of vitamin D₃ daily saw reduced monthly headache days, attack duration, severe headaches, and analgesic use, compared with placebo. Other nutrients implicated in migraine include coenzyme Q10, calcium, folic acid, vitamin B₆, and vitamin B₁.

“What should a patient with migraine do with all of this information? First, eat a healthy and balanced diet,” Dr. Friedman said. “Sources of dietary zinc include red meat, nuts, legumes, poultry, shellfish (especially oysters), whole grains, some cereals, and even dark chocolate. The recommended daily dosage of zinc is 9.5 mg in men and 7 mg in women. Most people get enough zinc in their diet; vegetarians, vegans, pregnant or breastfeeding women, and adults over age 65 may need to take supplemental zinc.”

Dr. Liu and colleagues’ work was supported by China’s National Natural Science Foundation. The investigators reported no financial conflicts of interest. Dr. Friedman has received financial support from Alder, Allergan, Amgen, Biohaven, Eli Lilly, Merck, Teva, and other pharmaceutical manufacturers.

Short bouts of intense exercise may help protect the brain from age-related cognitive decline by increasing production of a key protein involved in neuroplasticity, learning, and memory, new research suggests.

In a small study of healthy adults, 6 minutes of high-intensity cycling increased circulating levels of brain-derived neurotrophic factor (BDNF) to a significantly greater extent than prolonged light cycling or fasting.

However, the data do not suggest that 6 minutes of high-intensity exercise “wards off dementia,” cautioned lead investigator Travis Gibbons, MSc, PhD candidate in environmental physiology at the University of Otago (New Zealand), Dunedin, and now postdoctoral fellow at the University of British Columbia – Okanagan, Kelowna.

“Like all science, this is just a small piece that supports a potential mechanistic role for how exercise might improve brain health,” Dr. Gibbons told this news organization.

The findings were published online in the Journal of Physiology.
 

Targeting BDNF

Both intermittent fasting and exercise have previously been shown to have potent neuroprotective effects; and an acute upregulation of BDNF appears to be a common mechanistic link.

To tease apart the influence of fasting and exercise on BDNF production, Dr. Gibbons and colleagues studied 12 aerobically fit, healthy men (n = 6) and women (n = 6) aged 20-40 years.

In a study that employed a repeated-measures crossover design, they assessed circulating BDNF levels after a 20-hour fast, prolonged (90-min) light cycling, short (6-min) high-intensity cycling, and combined fasting and exercise.

Six minutes of high-intensity exercise appeared to be the most efficient way to increase BDNF.

Fasting for 20 hours led to a ninefold increase in ketone body delivery to the brain but had no effect on any metric of BDNF in peripheral circulation at rest or during exercise.

Six minutes of high-intensity exercise increased every metric of circulating BDNF four to five times more than prolonged low-intensity exercise.

In addition, the increase in plasma-derived BDNF correlated with a sixfold increase in circulating lactate irrespective of feeding or fasting state.
 

Lactate delivery?

“My leading theory is that, during and following intense exercise, lactate produced by muscles is delivered and consumed by the brain,” Dr. Gibbons noted.

“It takes high-intensity exercise to provoke this ‘cerebral substrate switch’ from glucose to lactate. Critically, this cerebral substrate switch has been shown to contribute to the early processes that upregulate BDNF production in the brain,” he said.

However, “Whether this translates to ‘warding off dementia’ is not clear,” Dr. Gibbons added.

The study also suggests that increases in plasma volume and platelet concentration appear to play a role in concentrating BDNF in the circulation during exercise.

The investigators note that BDNF and other neurotrophic-based pharmaceutical therapies have shown “great promise” in slowing and even arresting neurodegenerative processes in animals, but attempts to harness the protective power of BDNF in human neurodegeneration have thus far failed.

“Whether episodically upregulating BDNF production with intense exercise is an effective strategy to curb age-related cognitive decline in humans is unknown, but animal models indicate that it is and that BDNF plays a primary role,” the researchers write.

Funding for the study was provided by the Healthcare Otago Charitable Trust. The investigators have reported no relevant financial relationships.

Delay in treatment will cost hospital millions

A Texas hospital must pay a multimillion-dollar judgment for failing to treat a woman’s spinal injury in time to prevent paralysis, according to a report on WFAA.com, among other news sites.

On March 21, 2019, Judy “Jessie” Adams, then part of a singing-songwriting duo with her husband, Richard, went to Premier Interventional Pain Management, in Flower Mound, Tex., prior to the couple’s drive to Ohio for a funeral. At Premier, Jesse received an epidural steroid injection (ESI) that she hoped would ease her back pain during the long drive.

Instead, the injection ended up increasing her pain.

“He [the pain physician] gave me the shot, but I couldn’t feel my legs. They were tingling, but I couldn’t feel them,” Mrs. Adams explained. “The pain was so bad in my back.” In their suit, Adams and her husband alleged that the doctor had probably “nicked a blood vessel during the ESI procedure, causing Jessie to hemorrhage.” (The couple’s suit against the doctor was settled prior to trial.)

Mrs. Adams remained under observation at the pain facility for about 1½ hours, at which point she was taken by ambulance to nearby Texas Health Presbyterian Hospital. There, in the emergency department, staff ordered a “STAT MRI” in preparation for an emergency laminectomy.

For reasons that remain murky, the MRI wasn’t performed for 1 hour and 37 minutes. The emergency laminectomy itself wasn’t started until more than 5 hours after Adams had been admitted to the ED. This was a direct violation of hospital protocol, which required that emergency surgeries be performed within 1 hour of admittance in the first available surgical suite. (At trial, Mrs. Adams’s attorneys from Lyons & Simmons offered evidence that a suite became available 49 minutes after Adams had arrived at the ED.)

During the wait, Mrs. Adams continued to experience excruciating pain. “I kept screaming: ‘Help me,’ ” she recalled. At trial, her attorneys argued that the hospital’s delay in addressing her spinal emergency led directly to her current paralysis, which keeps her confined to a wheelchair and renders her incontinent.

The hospital disagreed. In court, it maintained that Mrs. Adams was already paralyzed when she arrived at the ED and that there was no delay in care.

The jury saw things differently, however. Siding with the plaintiffs, it awarded Mrs. Adams and her husband $10.1 million, including $500,000 for Mr. Adams’s loss of future earnings and $1 million for his “loss of consortium” with his wife.

Their music career now effectively over, Mr. Adams spends most of his time taking care of Mrs. Adams.

“Music was our lifeblood for so many years, and he can’t do it anymore,” Mrs. Adams said. “He goes upstairs to play his guitar and write, and suddenly I need him to come and cath me. I just feel like I’m going to wake up from this bad dream, but it’s the same routine.”
 

Two doctors are absolved in woman’s sudden death

In a 3-2 decision in December 2022, the Pennsylvania Supreme Court ruled that the state’s 2-year statute of limitations in wrongful-death cases applies even in cases in which plaintiffs fail to identify the cause of death in a timely manner, as a report in the Claims Journal indicates.

The decision stems from a lawsuit filed by Linda Reibenstein on behalf of her mother, Mary Ann Whitman, who died in late April 2010 from a ruptured aortic aneurysm.

On April 12, 2010, Ms. Whitman visited Patrick D. Conaboy, MD, a Scranton family physician, complaining of a persistent cough, fever, and lower-back pain. Following an initial examination, Dr. Conaboy ordered an aortic duplex ultrasound scan and a CT scan of the patient’s abdomen.

The ultrasound was performed by radiologist Charles Barax, MD, who reviewed both scans. He identified a “poorly visualized aortic aneurysm.” At this point, Dr. Conaboy referred Ms. Whitman to a vascular surgeon. But before this visit could take place, Whitman’s aneurysm ruptured, killing her. This was listed as the medical cause of death on the patient’s death certificate.

In April 2011, Ms. Reibenstein filed a claim against Dr. Barax, alleging that he had failed to gauge the severity of her mother’s condition. Ms. Reibenstein’s attorney wasn’t able to question Dr. Barax on the record until well after the state’s 2-year statute of limitations had elapsed. When he did testify, Dr. Barax explained that the scans’ image quality prevented him from determining whether Whitman’s aneurysm was rupturing or simply bleeding. Despite this, he insisted that he had warned Dr. Conaboy of the potential for Ms. Whitman’s aneurysm to rupture.

In March 2016, nearly 6 years after her mother’s death, Ms. Reibenstein filed a new lawsuit, this one against Dr. Conaboy, whom she alleged had failed to properly treat her mother’s condition. Dr. Conaboy, in turn, asked the court for summary judgment – that is, a judgment in his favor without a full trial – arguing that the state’s window for filing a wrongful-death claim had long since closed. For their part, Ms. Reibenstein and her attorney argued that the state’s 2-year statute of limitations didn’t start until the plaintiff had discovered the cause of her mother’s death.

Initially refusing to dismiss the case, a lower court reconsidered Dr. Conaboy’s motion for summary judgment and ruled that Ms. Reibenstein had failed to present any evidence of “affirmative misrepresentation or fraudulent concealment.” In other words, in the absence of any willful attempt on the part of the defendant to hide the legal cause of death, which includes “acts, omissions, or events having some causative connection with the death,” the statute of limitations remained in effect, and the defendant’s motion was thereby granted.

Continuing the legal seesaw, a state appeals court reversed the lower-court ruling. Noting that the Pennsylvania malpractice statute was ambiguous, the court argued that it should be interpreted in a way that protects plaintiffs who seek “fair compensation” but encounter willfully erected obstacles in pursuit of their claim.

Dr. Conaboy then took his case to the state’s highest court. In its majority decision, the Pennsylvania Supreme Court staked out a narrow definition of cause of death – one based on the death certificate – and ruled that only willful fraud in that document would constitute the necessary condition for halting the claim’s clock. Furthermore, the high court said, when lawmakers adopted the Medical Care Availability and Reduction of Error Act in 2002, they did so with no guarantee “that all of the information necessary to sustain a claim will be gathered in the limitations period.”

Similarly, the court ruled, “at some point the clock must run out, lest health care providers remain subject to liability exposure indefinitely, with the prospect of a trial marred by the death or diminished memory of material witnesses or the loss of critical evidence.”

Ms. Reibenstein’s attorney wasn’t able to question Dr. Barax on the record until well after the state’s 2-year statute of limitations had elapsed. When he did testify, Dr. Barax explained that the scans’ image quality prevented him from determining whether Whitman’s aneurysm was rupturing or simply bleeding. Despite this, he insisted that he had warned Dr. Conaboy of the potential for Ms. Whitman’s aneurysm to rupture.

In March 2016, nearly 6 years after her mother’s death, Ms. Reibenstein filed a new lawsuit, this one against Dr. Conaboy, whom she alleged had failed to properly treat her mother’s condition. Dr. Conaboy, in turn, asked the court for summary judgment – that is, a judgment in his favor without a full trial – arguing that the state’s window for filing a wrongful-death claim had long since closed. For their part, Ms. Reibenstein and her attorney argued that the state’s 2-year statute of limitations didn’t start until the plaintiff had discovered the cause of her mother’s death.

Initially refusing to dismiss the case, a lower court reconsidered Dr. Conaboy’s motion for summary judgment and ruled that Ms. Reibenstein had failed to present any evidence of “affirmative misrepresentation or fraudulent concealment.” In other words, in the absence of any willful attempt on the part of the defendant to hide the legal cause of death, which includes “acts, omissions, or events having some causative connection with the death,” the statute of limitations remained in effect, and the defendant’s motion was thereby granted.

Continuing the legal seesaw, a state appeals court reversed the lower-court ruling. Noting that the Pennsylvania malpractice statute was ambiguous, the court argued that it should be interpreted in a way that protects plaintiffs who seek “fair compensation” but encounter willfully erected obstacles in pursuit of their claim.

Dr. Conaboy then took his case to the state’s highest court. In its majority decision, the Pennsylvania Supreme Court staked out a narrow definition of cause of death – one based on the death certificate – and ruled that only willful fraud in that document would constitute the necessary condition for halting the claim’s clock. Furthermore, the high court said, when lawmakers adopted the Medical Care Availability and Reduction of Error Act in 2002, they did so with no guarantee “that all of the information necessary to sustain a claim will be gathered in the limitations period.”

Similarly, the court ruled, “at some point the clock must run out, lest health care providers remain subject to liability exposure indefinitely, with the prospect of a trial marred by the death or diminished memory of material witnesses or the loss of critical evidence.”

Delay in treatment will cost hospital millions

A Texas hospital must pay a multimillion-dollar judgment for failing to treat a woman’s spinal injury in time to prevent paralysis, according to a report on WFAA.com, among other news sites.

On March 21, 2019, Judy “Jessie” Adams, then part of a singing-songwriting duo with her husband, Richard, went to Premier Interventional Pain Management, in Flower Mound, Tex., prior to the couple’s drive to Ohio for a funeral. At Premier, Jesse received an epidural steroid injection (ESI) that she hoped would ease her back pain during the long drive.

Instead, the injection ended up increasing her pain.

“He [the pain physician] gave me the shot, but I couldn’t feel my legs. They were tingling, but I couldn’t feel them,” Mrs. Adams explained. “The pain was so bad in my back.” In their suit, Adams and her husband alleged that the doctor had probably “nicked a blood vessel during the ESI procedure, causing Jessie to hemorrhage.” (The couple’s suit against the doctor was settled prior to trial.)

Mrs. Adams remained under observation at the pain facility for about 1½ hours, at which point she was taken by ambulance to nearby Texas Health Presbyterian Hospital. There, in the emergency department, staff ordered a “STAT MRI” in preparation for an emergency laminectomy.

For reasons that remain murky, the MRI wasn’t performed for 1 hour and 37 minutes. The emergency laminectomy itself wasn’t started until more than 5 hours after Adams had been admitted to the ED. This was a direct violation of hospital protocol, which required that emergency surgeries be performed within 1 hour of admittance in the first available surgical suite. (At trial, Mrs. Adams’s attorneys from Lyons & Simmons offered evidence that a suite became available 49 minutes after Adams had arrived at the ED.)

During the wait, Mrs. Adams continued to experience excruciating pain. “I kept screaming: ‘Help me,’ ” she recalled. At trial, her attorneys argued that the hospital’s delay in addressing her spinal emergency led directly to her current paralysis, which keeps her confined to a wheelchair and renders her incontinent.

The hospital disagreed. In court, it maintained that Mrs. Adams was already paralyzed when she arrived at the ED and that there was no delay in care.

The jury saw things differently, however. Siding with the plaintiffs, it awarded Mrs. Adams and her husband $10.1 million, including $500,000 for Mr. Adams’s loss of future earnings and $1 million for his “loss of consortium” with his wife.

Their music career now effectively over, Mr. Adams spends most of his time taking care of Mrs. Adams.

“Music was our lifeblood for so many years, and he can’t do it anymore,” Mrs. Adams said. “He goes upstairs to play his guitar and write, and suddenly I need him to come and cath me. I just feel like I’m going to wake up from this bad dream, but it’s the same routine.”
 

Two doctors are absolved in woman’s sudden death

In a 3-2 decision in December 2022, the Pennsylvania Supreme Court ruled that the state’s 2-year statute of limitations in wrongful-death cases applies even in cases in which plaintiffs fail to identify the cause of death in a timely manner, as a report in the Claims Journal indicates.

The decision stems from a lawsuit filed by Linda Reibenstein on behalf of her mother, Mary Ann Whitman, who died in late April 2010 from a ruptured aortic aneurysm.

On April 12, 2010, Ms. Whitman visited Patrick D. Conaboy, MD, a Scranton family physician, complaining of a persistent cough, fever, and lower-back pain. Following an initial examination, Dr. Conaboy ordered an aortic duplex ultrasound scan and a CT scan of the patient’s abdomen.

The ultrasound was performed by radiologist Charles Barax, MD, who reviewed both scans. He identified a “poorly visualized aortic aneurysm.” At this point, Dr. Conaboy referred Ms. Whitman to a vascular surgeon. But before this visit could take place, Whitman’s aneurysm ruptured, killing her. This was listed as the medical cause of death on the patient’s death certificate.

In April 2011, Ms. Reibenstein filed a claim against Dr. Barax, alleging that he had failed to gauge the severity of her mother’s condition. Ms. Reibenstein’s attorney wasn’t able to question Dr. Barax on the record until well after the state’s 2-year statute of limitations had elapsed. When he did testify, Dr. Barax explained that the scans’ image quality prevented him from determining whether Whitman’s aneurysm was rupturing or simply bleeding. Despite this, he insisted that he had warned Dr. Conaboy of the potential for Ms. Whitman’s aneurysm to rupture.

In March 2016, nearly 6 years after her mother’s death, Ms. Reibenstein filed a new lawsuit, this one against Dr. Conaboy, whom she alleged had failed to properly treat her mother’s condition. Dr. Conaboy, in turn, asked the court for summary judgment – that is, a judgment in his favor without a full trial – arguing that the state’s window for filing a wrongful-death claim had long since closed. For their part, Ms. Reibenstein and her attorney argued that the state’s 2-year statute of limitations didn’t start until the plaintiff had discovered the cause of her mother’s death.

Persistent postconcussion symptoms (PPCS) are tied to a significantly increased risk of developing subsequent depressive symptoms, new research shows.

Results of a large meta-analysis that included 18 studies and more than 9,000 patients showed a fourfold higher risk of developing depressive symptoms in those with PPCS versus those without PPCS.

“In this meta-analysis, experiencing PPCS was associated with a higher risk of experiencing depressive symptoms,” write the investigators, led by Maude Lambert, PhD, of the School of Psychology, University of Ottawa, and Bloorview Research Institute, Toronto.

“There are several important clinical and health policy implications of the findings. Most notably, the development of strategies for effective prevention and earlier intervention to optimize mental health recovery following a concussion should be supported,” they add.

The study was published online  in JAMA Network Open.
 

‘Important minority’

An “important minority” of 15%-30% of those with concussions continue to experience symptoms for months, or even years, following the injury, the investigators note.

Symptoms vary but can include headaches, fatigue, dizziness, cognitive difficulties, and emotional changes, which can “significantly impact an individual’s everyday functioning.”

The association between PPCS and mental health outcomes “has emerged as an area of interest” over the past decade, with multiple studies pointing to bidirectional associations between depressive symptoms and PPCS, the researchers note. Individuals with PPCS are at significantly higher risk of experiencing depressive symptoms, and depressive symptoms, in turn, predict more prolonged postconcussion recovery, they add.

The authors conducted a previous scoping review that showed individuals with PPCS had “greater mental health difficulties than individuals who recovered from concussion or healthy controls.”

But “quantitative summaries evaluating the magnitude and nature of the association between PPCS and mental health outcomes were not conducted,” so they decided to conduct a follow-up meta-analysis to corroborate the hypothesis that PPCS may be associated with depressive symptoms.

The researchers also wanted to “investigate potential moderators of that association and determine whether the association between depressive symptoms and PPCS differed based on age, sex, mental illness, history of concussion, and time since the injury.”

This could have “significant public health implications” as it represents an “important step” toward understanding the association between PPCS and mental health, paving the way for the “development of optimal postconcussion intervention strategies, targeting effective prevention and earlier intervention to enhance recovery trajectories, improve mental health, and promote well-being following concussion.”

To be included in the meta-analysis, a study had to focus on participants who had experienced a concussion, diagnosed by a health care professional, or as classified by diagnostic measures, and who experienced greater than or equal to 1 concussion symptom lasting greater than 4 weeks.

There was no explicit upper limit on duration, and individuals of all ages were eligible.

Depressive symptoms were defined as “an outcome that must be measured by a validated and standardized measure of depression.”
 

Biopsychosocial model

Of 580 reports assessed for eligibility, 18 were included in the meta-analysis, incorporating a total of 9,101 participants, with a median (range) sample size of 154 (48-4,462) participants and a mean (SD) participant age of 33.7 (14.4) years.

The mean length of time since the concussion was 21.3 (18.7) weeks. Of the participants, a mean of 36.1% (11.1%) had a history of greater than or equal to 2 concussions.

Close to three-quarters of the studies (72%) used a cross-sectional design, with most studies conducted in North America, and the remaining conducted in Europe, China, and New Zealand.

The researchers found a “significant positive association” between PPCS and postinjury depressive symptoms (odds ratio, 4.87; 95% confidence interval, 3.01-7.90; P < .001), “representing a large effect size.”

Funnel plot and Egger test analyses “suggested the presence of a publication bias.” However, even after accounting for publication bias, the effect size “of large magnitude” remained, the authors report (OR, 4.56; 95% CI, 2.82-7.37; P < .001).

No significant moderators were identified, “likely due to the small number of studies included,” they speculate.

They note that the current study “does not allow inference about the causal directionality of the association” between PPCS and postinjury depressive symptoms, so the question remains: Do PPCS induce depressive symptoms, or do depressive symptoms induce PPCS?”

Despite this unanswered question, the findings still have important clinical and public health implications, highlighting “the need for a greater understanding of the mechanisms of development and etiology of depressive symptoms postconcussion” and emphasizing “the necessary emergence for timely and effective treatment interventions for depressive symptoms to optimize the long-term prognosis of concussion,” the authors note.

They add that several research teams “have aimed to gain more insight into the etiology and underlying mechanisms of development and course of mental health difficulties in individuals who experience a concussion” and have arrived at a biopsychosocial framework, in light of “the myriad of contributing physiological, biological, and psychosocial factors.”

They recommend the establishment of “specialized multidisciplinary or interdisciplinary concussion care programs should include health care professionals with strong clinical foundations and training in mental health conditions.”
 

Speedy multidisciplinary care

Commenting on the research, Charles Tator, MD, PhD, professor of neurosurgery, University of Toronto, Division of Neurosurgery, Toronto Western Hospital, said the researchers “performed a thorough systematic review” showing “emphatically that depression occurs in this population.”

Dr. Tator, the director of the Canadian Concussion Centre, who was not involved with the current study, continued: “Nowadays clinical discoveries are validated through a progression of case reports, single-center retrospective cohort studies like ours, referenced by [Dr.] Lambert et al., and then confirmatory systematic reviews, each adding important layers of evidence.”

“This evaluative process has now endorsed the importance of early treatment of mental health symptoms in patients with persisting symptoms, which can include depression, anxiety, and PTSD,” he said.

He recommended that treatment should start with family physicians and nurse practitioners “but may require escalation to psychologists and social workers and then to psychiatrists who are often more skilled in medication selection.”

He encouraged “speedy multidisciplinary care,” noting that the possibility of suicide is worrisome.

No source of study funding was listed. A study coauthor, Shannon Scratch, PhD, has reported receiving funds from the Holland Bloorview Kids Rehabilitation Hospital Foundation (via the Holland Family Professorship in Acquired Brain Injury) during the conduct of this study. No other disclosures were reported. Dr. Tator has reported no relevant financial relationships.

Sleep complaints by patients with a major depressive episode (MDE) may be a red flag signaling a higher risk for developing other psychiatric disorders, new research suggests.

Investigators studied 3-year incidence rates of psychiatric disorders in almost 3,000 patients experiencing an MDE. Results showed that having a history of difficulty falling asleep, early morning awakening, and hypersomnia increased risk for incident psychiatric disorders.

“The findings of this study suggest the potential value of including insomnia and hypersomnia in clinical assessments of all psychiatric disorders,” write the investigators, led by Bénédicte Barbotin, MD, Département de Psychiatrie et d’Addictologie, Assistance Publique-Hôpitaux de Paris, Hôpital Bichat-Claude Bernard, France.

“Insomnia and hypersomnia symptoms may be prodromal transdiagnostic biomarkers and easily modifiable therapeutic targets for the prevention of psychiatric disorders,” they add.

The findings were published online recently in the Journal of Clinical Psychiatry.


 

Bidirectional association

The researchers note that sleep disturbance is “one of the most common symptoms” associated with major depressive disorder (MDD) and may be “both a consequence and a cause.”

Moreover, improving sleep disturbances for patients with an MDE “tends to improve depressive symptom and outcomes,” they add.

Although the possibility of a bidirectional association between MDEs and sleep disturbances “offers a new perspective that sleep complaints might be a predictive prodromal symptom,” the association of sleep complaints with the subsequent development of other psychiatric disorders in MDEs “remains poorly documented,” the investigators write.

The observation that sleep complaints are associated with psychiatric complications and adverse outcomes, such as suicidality and substance overdose, suggests that longitudinal studies “may help to better understand these relationships.”

To investigate these issues, the researchers examined three sleep complaints among patients with MDE: trouble falling asleep, early morning awakening, and hypersomnia. They adjusted for an array of variables, including antisocial personality disorders, use of sedatives or tranquilizers, sociodemographic characteristics, MDE severity, poverty, obesity, educational level, and stressful life events.

They also used a “bifactor latent variable approach” to “disentangle” a number of effects, including those shared by all psychiatric disorders; those specific to dimensions of psychopathology, such as internalizing dimension; and those specific to individual psychiatric disorders, such as dysthymia.

“To our knowledge, this is the most extensive prospective assessment [ever conducted] of associations between sleep complaints and incident psychiatric disorders,” the investigators write.

They drew on data from Waves 1 and 2 of the National Epidemiological Survey on Alcohol and Related Conditions, a large nationally representative survey conducted in 2001-2002 (Wave 1) and 2004-2005 (Wave 2) by the National Institute on Alcoholism and Alcohol Abuse.

The analysis included 2,864 participants who experienced MDE in the year prior to Wave 1 and who completed interviews at both waves.

Researchers assessed past-year DSM-IV Axis I disorders and baseline sleep complaints at Wave 1, as well as incident DSM-IV Axis I disorders between the two waves – including substance use, mood, and anxiety disorders.
 

Screening needed?

Results showed a wide range of incidence rates for psychiatric disorders between Wave 1 and Wave 2, ranging from 2.7% for cannabis use to 8.2% for generalized anxiety disorder.

The lifetime prevalence of sleep complaints was higher among participants who developed a psychiatric disorder between the two waves than among those who did not have sleep complaints. The range (from lowest to highest percentage) is shown in the accompanying table.

A higher number of sleep complaints was also associated with higher percentages of psychiatric disorders.

Hypersomnia, in particular, significantly increased the odds of having another psychiatric disorder. For patients with MDD who reported hypersomnia, the mean number of sleep disorders was significantly higher than for patients without hypersomnia (2.08 vs. 1.32; P < .001).

“This explains why hypersomnia appears more strongly associated with the incidence of psychiatric disorders,” the investigators write.

After adjusting for sociodemographic and clinical characteristics and antisocial personality disorder, the effects shared across all sleep complaints were “significantly associated with the incident general psychopathology factor, representing mechanisms that may lead to incidence of all psychiatric disorder in the model,” they add.

The researchers note that insomnia and hypersomnia can impair cognitive function, decision-making, problem-solving, and emotion processing networks, thereby increasing the onset of psychiatric disorders in vulnerable individuals.

Shared biological determinants, such as monoamine neurotransmitters that play a major role in depression, anxiety, substance use disorders, and the regulation of sleep stages, may also underlie both sleep disturbances and psychiatric disorders, they speculate.

“These results suggest the importance of systematically assessing insomnia and hypersomnia when evaluating psychiatric disorders and considering these symptoms as nonspecific prodromal or at-risk symptoms, also shared with suicidal behaviors,” the investigators write.

“In addition, since most individuals who developed a psychiatric disorder had at least one sleep complaint, all psychiatric disorders should be carefully screened among individuals with sleep complaints,” they add.
 

Transdiagnostic phenomenon

In a comment, Roger McIntyre, MD, professor of psychiatry and pharmacology at the University of Toronto, and head of the Mood Disorders Psychopharmacology Unit, noted that the study replicates previous observations that a bidirectional relationship exists between sleep disturbances and mental disorders and that there “seems to be a relationship between sleep disturbance and suicidality that is bidirectional.”

Sleep complaints by patients with a major depressive episode (MDE) may be a red flag signaling a higher risk for developing other psychiatric disorders, new research suggests.

Investigators studied 3-year incidence rates of psychiatric disorders in almost 3,000 patients experiencing an MDE. Results showed that having a history of difficulty falling asleep, early morning awakening, and hypersomnia increased risk for incident psychiatric disorders.

“The findings of this study suggest the potential value of including insomnia and hypersomnia in clinical assessments of all psychiatric disorders,” write the investigators, led by Bénédicte Barbotin, MD, Département de Psychiatrie et d’Addictologie, Assistance Publique-Hôpitaux de Paris, Hôpital Bichat-Claude Bernard, France.

“Insomnia and hypersomnia symptoms may be prodromal transdiagnostic biomarkers and easily modifiable therapeutic targets for the prevention of psychiatric disorders,” they add.

The findings were published online recently in the Journal of Clinical Psychiatry.


 

Bidirectional association

The researchers note that sleep disturbance is “one of the most common symptoms” associated with major depressive disorder (MDD) and may be “both a consequence and a cause.”

Moreover, improving sleep disturbances for patients with an MDE “tends to improve depressive symptom and outcomes,” they add.

Although the possibility of a bidirectional association between MDEs and sleep disturbances “offers a new perspective that sleep complaints might be a predictive prodromal symptom,” the association of sleep complaints with the subsequent development of other psychiatric disorders in MDEs “remains poorly documented,” the investigators write.

The observation that sleep complaints are associated with psychiatric complications and adverse outcomes, such as suicidality and substance overdose, suggests that longitudinal studies “may help to better understand these relationships.”

To investigate these issues, the researchers examined three sleep complaints among patients with MDE: trouble falling asleep, early morning awakening, and hypersomnia. They adjusted for an array of variables, including antisocial personality disorders, use of sedatives or tranquilizers, sociodemographic characteristics, MDE severity, poverty, obesity, educational level, and stressful life events.

They also used a “bifactor latent variable approach” to “disentangle” a number of effects, including those shared by all psychiatric disorders; those specific to dimensions of psychopathology, such as internalizing dimension; and those specific to individual psychiatric disorders, such as dysthymia.

“To our knowledge, this is the most extensive prospective assessment [ever conducted] of associations between sleep complaints and incident psychiatric disorders,” the investigators write.

They drew on data from Waves 1 and 2 of the National Epidemiological Survey on Alcohol and Related Conditions, a large nationally representative survey conducted in 2001-2002 (Wave 1) and 2004-2005 (Wave 2) by the National Institute on Alcoholism and Alcohol Abuse.

The analysis included 2,864 participants who experienced MDE in the year prior to Wave 1 and who completed interviews at both waves.

Researchers assessed past-year DSM-IV Axis I disorders and baseline sleep complaints at Wave 1, as well as incident DSM-IV Axis I disorders between the two waves – including substance use, mood, and anxiety disorders.
 

Screening needed?

Results showed a wide range of incidence rates for psychiatric disorders between Wave 1 and Wave 2, ranging from 2.7% for cannabis use to 8.2% for generalized anxiety disorder.

The lifetime prevalence of sleep complaints was higher among participants who developed a psychiatric disorder between the two waves than among those who did not have sleep complaints. The range (from lowest to highest percentage) is shown in the accompanying table.

A higher number of sleep complaints was also associated with higher percentages of psychiatric disorders.

Hypersomnia, in particular, significantly increased the odds of having another psychiatric disorder. For patients with MDD who reported hypersomnia, the mean number of sleep disorders was significantly higher than for patients without hypersomnia (2.08 vs. 1.32; P < .001).

“This explains why hypersomnia appears more strongly associated with the incidence of psychiatric disorders,” the investigators write.

After adjusting for sociodemographic and clinical characteristics and antisocial personality disorder, the effects shared across all sleep complaints were “significantly associated with the incident general psychopathology factor, representing mechanisms that may lead to incidence of all psychiatric disorder in the model,” they add.

The researchers note that insomnia and hypersomnia can impair cognitive function, decision-making, problem-solving, and emotion processing networks, thereby increasing the onset of psychiatric disorders in vulnerable individuals.

Shared biological determinants, such as monoamine neurotransmitters that play a major role in depression, anxiety, substance use disorders, and the regulation of sleep stages, may also underlie both sleep disturbances and psychiatric disorders, they speculate.

“These results suggest the importance of systematically assessing insomnia and hypersomnia when evaluating psychiatric disorders and considering these symptoms as nonspecific prodromal or at-risk symptoms, also shared with suicidal behaviors,” the investigators write.

“In addition, since most individuals who developed a psychiatric disorder had at least one sleep complaint, all psychiatric disorders should be carefully screened among individuals with sleep complaints,” they add.
 

Transdiagnostic phenomenon

In a comment, Roger McIntyre, MD, professor of psychiatry and pharmacology at the University of Toronto, and head of the Mood Disorders Psychopharmacology Unit, noted that the study replicates previous observations that a bidirectional relationship exists between sleep disturbances and mental disorders and that there “seems to be a relationship between sleep disturbance and suicidality that is bidirectional.”

He added that he appreciated the fact that the investigators “took this knowledge one step further; and what they are saying is that within the syndrome of depression, it is the sleep disturbance that is predicting future problems.”

Dr. McIntyre, who is also chairman and executive director of the Brain and Cognitive Discover Foundation in Toronto, was not involved with the study.

Long COVID is typically characterized by anosmia and dysgeusia, cognitive impairment, dyspnea, weakness, and palpitations, with younger patients showing greatest improvements at 1 year, according to a nationwide cohort study conducted in Israel.

These findings help define long COVID, guiding providers and patients through the recovery process, Barak Mizrahi, MSc, of KI Research Institute, Kfar Malal, Israel, and colleagues reported.

“To provide efficient continuous treatment and prevent adverse events related to potential long term effects and delayed symptoms of COVID-19, determining the magnitude and severity of this phenomenon and distinguishing it from similar clinical manifestations that occur normally or following infections with other pathogens is essential,” the investigators wrote in The BMJ.

To this end, they conducted a retrospective, nationwide cohort study involving 1,913,234 people who took a polymerase chain reaction test for SARS-CoV-2 between March 1, 2020, and Oct. 1, 2021. They compared a range of long-term outcomes at different intervals post infection, and compared these trends across subgroups sorted by age, sex, and variant. Outcomes ranged broadly, including respiratory disorders, cough, arthralgia, weakness, hair loss, and others.

The investigators compared hazard ratios for each of these outcomes among patients who tested positive versus those who tested negative at three intervals after testing: 30-90 days, 30-180 days, and 180-360 days. Statistically significant differences in the risks of these outcomes between infected versus uninfected groups suggested that COVID was playing a role.

“The health outcomes that represent long COVID showed a significant increase in both early and late phases,” the investigators wrote. These outcomes included anosmia and dysgeusia, cognitive impairment, dyspnea, weakness, and palpitations. In contrast, chest pain, myalgia, arthralgia, cough, and dizziness were associated with patients who were in the early phase, but not the late phase of long COVID.

“Vaccinated patients with a breakthrough SARS-CoV-2 infection had a lower risk for dyspnea and similar risk for other outcomes compared with unvaccinated infected patients,” the investigators noted.

For the long COVID outcomes, plots of risk differences over time showed that symptoms tended to get milder or resolve within a few months to a year. Patients 41-60 years were most likely to be impacted by long COVID outcomes, and show least improvement at 1 year, compared with other age groups.

“We believe that these findings will shed light on what is ‘long COVID’, support patients and doctors, and facilitate better and more efficient care,” Mr. Mizrahi and coauthor Maytal Bivas-Benita, PhD said in a joint written comment. “Primary care physicians (and patients) will now more clearly understand what are the symptoms that might be related to COVID and for how long they might linger. This would help physicians monitor the patients efficiently, ease their patients’ concerns and navigate a more efficient disease management.”

They suggested that the findings should hold consistent for future variants, although they could not “rule out the possibility of the emergence of new and more severe variants which will be more virulent and cause a more severe illness.”

One “major limitation” of the study, according to Monica Verduzco-Gutierrez, MD, a physiatrist and professor and chair of rehabilitation medicine at the University of Texas Health Science Center, San Antonio, is the lack of data for fatigue and dysautonomia, which are “the major presentations” that she sees in her long COVID clinic.

“The authors of the article focus on the primary damage being related to the lungs, though we know this is a systemic disease beyond the respiratory system, with endothelial dysfunction and immune dysregulation,” Dr. Verduzco-Gutierrez, who is also director of COVID recovery at the University of Texas Health Science Center, said in an interview.

Although it was reassuring to see that younger adults with long COVID trended toward improvement, she noted that patients 41-60 years “still had pretty significant symptoms” after 12 months.

“That [age group comprises] probably the majority of my patients that I’m seeing in the long COVID clinic,” Dr. Verduzco-Gutierrez said. “If you look at the whole thing, it looks better, but then when you drill down to that age group where you’re seeing patients, then it’s not.”

Dr. Verduzco-Gutierrez is so busy managing patients with long COVID that new appointments in her clinic are now delayed until May 31, so most patients will remain under the care of their primary care providers. She recommended that these physicians follow guidance from the American Academy of Physical Medicine and Rehabilitation, who offer consensus statements based on clinical characteristics, with separate recommendations for pediatric patients.

Our understanding of long COVID will continue to improve, and with it, available recommendations, she predicted, but further advances will require persistent effort.

“I think no matter what this [study] shows us, more research is needed,” Dr. Verduzco-Gutierrez said. “We can’t just forget about it, just because there is a population of people who get better. What about the ones who don’t?”

The investigators and Dr. Verduzco-Gutierrez disclosed no conflicts of interest.

The ‘scheme’ in the name should have been a clue

Retirement. The shiny reward to a lifetime’s worth of working and saving. We’re all literally working to get there, some of us more to get there early, but current research reveals that early retirement isn’t the relaxing finish line we dream about, cognitively speaking.

FatCamera/Getty Images

Researchers at Binghamton (N.Y.) University set out to examine just how retirement plans affect cognitive performance. They started off with China’s New Rural Pension Scheme (scheme probably has a less negative connotation in Chinese), a plan that financially aids the growing rural retirement-age population in the country. Then they looked at data from the Chinese Health and Retirement Longitudinal Survey, which tests cognition with a focus on episodic memory and parts of intact mental status.

What they found was the opposite of what you would expect out of retirees with nothing but time on their hands.

The pension program, which had been in place for almost a decade, led to delayed recall, especially among women, supporting “the mental retirement hypothesis that decreased mental activity results in worsening cognitive skills,” the investigators said in a written statement.

There also was a drop in social engagement, with lower rates of volunteering and social interaction than people who didn’t receive the pension. Some behaviors, like regular alcohol consumption, did improve over the previous year, as did total health in general, but “the adverse effects of early retirement on mental and social engagement significantly outweigh the program’s protective effect on various health behaviors,” Plamen Nikolov, PhD, said about his research.

So if you’re looking to retire early, don’t skimp on the crosswords and the bingo nights. Stay busy in a good way. Your brain will thank you.
 

Indiana Jones and the First Smallpox Ancestor

Smallpox was, not that long ago, one of the most devastating diseases known to humanity, killing 300 million people in the 20th century alone. Eradicating it has to be one of medicine’s crowning achievements. Now it can only be found in museums, which is where it belongs.

J. Nakano, USCDCP/Pixnio

Here’s the thing with smallpox though: For all it did to us, we know frustratingly little about where it came from. Until very recently, the best available genetic evidence placed its emergence in the 17th century, which clashes with historical data. You know what that means, right? It’s time to dig out the fedora and whip, cue the music, and dig into a recently published study spanning continents in search of the mythical smallpox origin story.

We pick up in 2020, when genetic evidence definitively showed smallpox in a Viking burial site, moving the disease’s emergence a thousand years earlier. Which is all well and good, but there’s solid visual evidence that Egyptian pharaohs were dying of smallpox, as their bodies show the signature scarring. Historians were pretty sure smallpox went back about 4,000 years, but there was no genetic material to prove it.

Since there aren’t any 4,000-year-old smallpox germs laying around, the researchers chose to attack the problem another way – by burning down a Venetian catacomb, er, conducting a analysis of historical smallpox genetics to find the virus’s origin. By analyzing the genomes of various strains at different periods of time, they were able to determine that the variola virus had a definitive common ancestor. Some of the genetic components in the Viking-age sample, for example, persisted until the 18th century.

Armed with this information, the scientists determined that the first smallpox ancestor emerged about 3,800 years ago. That’s very close to the historians’ estimate for the disease’s emergence. Proof at last of smallpox’s truly ancient origin. One might even say the researchers chose wisely.

• Katalin Karikó, a biochemist, and Drew Weissman, an immunologist, “discovered how to enable messenger ribonucleic acid (mRNA) to enter cells without triggering the body’s immune system,” NIHF said, and that laid the foundation for the mRNA COVID-19 vaccines developed by Pfizer-BioNTech and Moderna. That, of course, led to the antivax movement, which has provided so much LOTME fodder over the years.
• Angela Hartley Brodie was a biochemist who discovered and developed a class of drugs called aromatase inhibitors, which can stop the production of hormones that fuel cancer cell growth and are used to treat breast cancer in 500,000 women worldwide each year.

We can’t mention all of the inductees for 2023 (our editor made that very clear), but we would like to offer a special shout-out to brothers Cyril (the first Cyril in the NIHF, by the way) and Louis Keller, who invented the world’s first compact loader, which eventually became the Bobcat skid-steer loader. Not really medical, you’re probably thinking, but we’re sure that someone, somewhere, at some time, used one to build a hospital, landscape a hospital, or clean up after the demolition of a hospital.

The ‘scheme’ in the name should have been a clue

Retirement. The shiny reward to a lifetime’s worth of working and saving. We’re all literally working to get there, some of us more to get there early, but current research reveals that early retirement isn’t the relaxing finish line we dream about, cognitively speaking.

Researchers at Binghamton (N.Y.) University set out to examine just how retirement plans affect cognitive performance. They started off with China’s New Rural Pension Scheme (scheme probably has a less negative connotation in Chinese), a plan that financially aids the growing rural retirement-age population in the country. Then they looked at data from the Chinese Health and Retirement Longitudinal Survey, which tests cognition with a focus on episodic memory and parts of intact mental status.

What they found was the opposite of what you would expect out of retirees with nothing but time on their hands.

The pension program, which had been in place for almost a decade, led to delayed recall, especially among women, supporting “the mental retirement hypothesis that decreased mental activity results in worsening cognitive skills,” the investigators said in a written statement.

There also was a drop in social engagement, with lower rates of volunteering and social interaction than people who didn’t receive the pension. Some behaviors, like regular alcohol consumption, did improve over the previous year, as did total health in general, but “the adverse effects of early retirement on mental and social engagement significantly outweigh the program’s protective effect on various health behaviors,” Plamen Nikolov, PhD, said about his research.

So if you’re looking to retire early, don’t skimp on the crosswords and the bingo nights. Stay busy in a good way. Your brain will thank you.
 

Indiana Jones and the First Smallpox Ancestor

Smallpox was, not that long ago, one of the most devastating diseases known to humanity, killing 300 million people in the 20th century alone. Eradicating it has to be one of medicine’s crowning achievements. Now it can only be found in museums, which is where it belongs.

Here’s the thing with smallpox though: For all it did to us, we know frustratingly little about where it came from. Until very recently, the best available genetic evidence placed its emergence in the 17th century, which clashes with historical data. You know what that means, right? It’s time to dig out the fedora and whip, cue the music, and dig into a recently published study spanning continents in search of the mythical smallpox origin story.

We pick up in 2020, when genetic evidence definitively showed smallpox in a Viking burial site, moving the disease’s emergence a thousand years earlier. Which is all well and good, but there’s solid visual evidence that Egyptian pharaohs were dying of smallpox, as their bodies show the signature scarring. Historians were pretty sure smallpox went back about 4,000 years, but there was no genetic material to prove it.

Since there aren’t any 4,000-year-old smallpox germs laying around, the researchers chose to attack the problem another way – by burning down a Venetian catacomb, er, conducting a analysis of historical smallpox genetics to find the virus’s origin. By analyzing the genomes of various strains at different periods of time, they were able to determine that the variola virus had a definitive common ancestor. Some of the genetic components in the Viking-age sample, for example, persisted until the 18th century.

Armed with this information, the scientists determined that the first smallpox ancestor emerged about 3,800 years ago. That’s very close to the historians’ estimate for the disease’s emergence. Proof at last of smallpox’s truly ancient origin. One might even say the researchers chose wisely.
 

The only hall of fame that really matters

LOTME loves the holiday season – the food, the gifts, the radio stations that play nothing but Christmas music – but for us the most wonderful time of the year comes just a bit later. No, it’s not our annual Golden Globes slap bet. Nope, not even the “excitement” of the College Football Playoff National Championship. It’s time for the National Inventors Hall of Fame to announce its latest inductees, and we could hardly sleep last night after putting cookies out for Thomas Edison. Fasten your seatbelts!
