CHICAGO - Patients 80 years or older undergoing primary total knee arthroplasty (TKA) have similar odds of complications, compared with 65- to 79-year-old patients, an analysis of more than 1.7 million cases suggests.

Priscilla Varghese, MBA, MS, and an MD candidate at State University of New York, Brooklyn, led the research, presented at the American Academy of Orthopaedic Surgeons 2022 annual meeting.

Ms. Varghese’s team queried a Medicare claims database for the years 2005-2014 and analyzed information from 295,908 octogenarians and 1.4 million control patients aged 65-79 who received TKA.

Study group patients were randomly matched to controls in a 1:5 ratio according to gender and comorbidities, including chronic obstructive pulmonary disease, congestive heart failure, diabetes, peripheral vascular disease, and kidney failure.

Octogenarians were found to have higher incidence and odds of 90-day readmission rates (10.59% vs. 9.35%; odds ratio, 1.15; 95% confidence interval, 1.13-1.16; P < .0001).   

Hospital stays were also longer (3.69 days ± 1.95 vs. 3.23 days ± 1.83; P < .0001), compared with controls.

Reassuring older patients

However, Ms. Varghese told this news organization she was surprised to find that the older group had equal incidence and odds of developing medical complications (1.26% vs. 1.26%; OR, 0.99; 95% CI, 0.96-1.03; P =.99).

“That’s a really important piece of information to have when we are advising 80-year-olds – to be able to say their risk of adverse outcomes is similar to someone who’s 10 years, 15 years younger,” she said. “It’s really reassuring.”

These results offer good news to older patients who might be hesitant to undergo the surgery, and good news in general as life expectancy increases and people stay active long into their later years, forecasting the need for more knee replacements.

The number of total knee replacements is expected to rise dramatically in the United States.

In a 2017 study published in Osteoarthritis Cartilage, the authors write, “the number of TKAs in the U.S., which already has the highest [incidence rate] of knee arthroplasty in the world, is expected to increase 143% by 2050.”

Thomas Fleeter, MD, an orthopedic surgeon practicing in Reston, Virginia, who was not involved in the study, told this news organization this study reinforces that “it’s OK to do knee replacements in elderly people; you just have to pick the right ones.”

He pointed out that the study also showed that the 80-and-older patients don’t have the added risk of loosening their mechanical components after the surgery, likely because they are less inclined than their younger counterparts to follow surgery with strenuous activities.

In a subanalysis, revision rates were also lower for the octogenarians (0.01% vs. 0.02% for controls).

Octogenarians who had TKA were found to have lower incidence and odds (1.6% vs. 1.93%; OR, 0.86; 95% CI, 0.83-0.88, P < .001) of implant-related complications, compared with the younger group.

The increased length of stay would be expected, Dr. Fleeter said, because those 80-plus may need a bit more help getting out of bed and may not have as much support at home.

A total knee replacement can have the substantial benefit of improving octogenarians’ ability to maintain their independence longer by facilitating driving or walking.

“It’s a small and manageable risk if you pick the right patients,” he said.

Demand for TKAs rises as population ages

As patients are living longer and wanting to maintain their mobility and as obesity rates are rising, more older patients will seek total knee replacements, especially since the payoff is high, Ms. Varghese noted.

“People who undergo this operation tend to show remarkable decreases in pain and increases in range of motion,” she said.

This study has the advantage of a more personalized look at risks of TKA because it stratifies age groups.

“The literature tends to look at the elderly population as one big cohort – 65 and older,” Ms. Varghese said. “We were able to provide patients more specific data.”

Ms. Varghese and Dr. Fleeter have disclosed no relevant financial relationships.

A congressional oversight subcommittee is investigating the Food and Drug Administration’s regulation of a high-risk heart pump, citing safety issues detailed by ProPublica.

The HeartWare Ventricular Assist Device, created to treat patients with severe heart failure, stopped meeting key federal standards as early as 2014. But the FDA took no decisive action even as those problems persisted, and thousands of Americans continued to be implanted with the pump.

By the end of 2020, the FDA had received more than 3,000 reports of deaths related to the HeartWare device, according to a ProPublica data analysis. A father of four died as his children tried to resuscitate him when his device suddenly stopped. A teenager died after vomiting blood in the middle of the night, while his mother struggled to restart a faulty pump.

“I am concerned by FDA’s slow action, over multiple administrations, to protect patients from this product despite early warning signs,” Rep. Raja Krishnamoorthi, D-Ill., said in a scathing letter sent March 22 to the agency’s commissioner, Robert Califf, MD.

Mr. Krishnamoorthi, the chairman of the U.S. House Committee on Oversight and Reform’s Subcommittee on Economic and Consumer Policy, requested information on how the FDA made regulatory decisions related to the HeartWare device and why it didn’t take further action.

The FDA did not provide comment to ProPublica on the subcommittee’s investigation and said it would respond directly to Mr. Krishnamoorthi. It also reiterated its response to ProPublica’s findings and said the agency had been closely overseeing the HeartWare device since 2012, with patient safety as its “highest priority.”

Medtronic, the company that acquired HeartWare in 2016, took the device off the market in June 2021. The company said that new data showed a competing heart pump had better outcomes. In response to the ProPublica investigation 2 months later, the company said it took the FDA’s inspections seriously and had worked closely with the agency to address issues with the device.

Medtronic declined to comment on the subcommittee’s investigation.

Mr. Krishnamoorthi asked in the letter if any steps were being taken to address how patients, doctors and other federal agencies are notified of problems that the FDA finds with medical devices.

Many patients told ProPublica they were never informed of issues with the HeartWare pump before or after their implants. Some people who still have the device said they weren’t told when it was taken off the market. Medtronic said in December it had confirmed 90% of U.S. patients had received notification of the HeartWare discontinuation, but that it was still working to reach the other 10%.

About 2,000 patients still had HeartWare pumps as of last year. The FDA and Medtronic recommended against removing those devices barring medical necessity because the surgery to do so carries a high risk.

In his letter, Mr. Krishnamoorthi gave the FDA a deadline of April 5 to respond.

Recent tests of 13 lots of the skeletal muscle relaxant Orphenadrine Citrate 100 mg Extended Release (ER) found unacceptably high levels of a nitrosamine impurity in the tablets, leading manufacturer Sandoz (Princeton, N.J.) to announce a voluntary recall of the lots on March 21.

The nitrosamine impurity detected (N-methyl-N-nitroso-2-[(2-methylphenyl)phenylmethoxy]ethanamine [NMOA or Nitroso-Orphenadrine]) may potentially be consumed at a level higher than the Food and Drug Administration’s Acceptable Daily Intake of 26.5 ng/day. Nitrosamines have carcinogenic potency when present above the allowable exposure limits, according to Sandoz, but the company said it “has not received any reports of adverse events related to the presence of a nitrosamine impurity in the lot.”

The Orphenadrine Citrate 100 mg ER Tablets were shipped to customers from August 2019 to April 2021 and have lot numbers of JX6411, JX6413, KC0723, KC3303, KE4348, KE7169, KE4349, KL3199, KM0072, KS3939, LA7704, LA7703, and LA9243.

The lots contain 100- and 1,000-count bottles of Orphenadrine Citrate ER Tablets, which are used as an adjunct to rest, physical therapy, and other measures for the relief of discomfort associated with acute painful musculoskeletal conditions.

The recall does not apply to any other strengths of Sandoz’s Orphenadrine Citrate ER Tablets or to other lot numbers of the product.

Sandoz advises that wholesalers and distributors should “immediately stop distribution of the recalled product and quarantine and return all recalled product in their inventory.” The company advises consumers to stop taking the recalled product and immediately consult with their physicians to obtain another prescription, notifying them of any problems that may be related to taking or using the tablets.

Sandoz says that retailers and consumers should contact Sedgwick directly by phone at 844-491-7869 or email at [email protected] to return the recalled product, and report adverse reactions to Sandoz by phone at (800) 525-8747 or by email at [email protected]. Adverse reactions and quality problems can be reported to the FDA’s MedWatch Adverse Event Reporting program either online, by regular mail, or by fax to 1-800-FDA-0178.

Can you keep it down? I’m trying to be boring

He chides his friends for not looking both ways before crossing the road. He is never questioned by the police because they fall asleep listening to him talk. He has won the office’s coveted perfect attendance award 10 years running. Look out, Dos Equis guy, you’ve got some new competition. That’s right, it’s the most boring man in the world.

For this boring study (sorry, study on boredom) conducted by English researchers and published in Personality and Social Psychology Bulletin, people were surveyed on various jobs and hobbies, ranking them by how exciting or boring they are, as well as how competent someone with those jobs/hobbies would be, their willingness to avoid someone with those jobs/hobbies, and how much they’d need to be paid to spend time with someone who had an undesirable job/hobby.

According to the British public, the most boring person in the world is a religious data analyst who likes to sleep and lives in a small town. In fact, spending time with this person is almost a full-time job on its own: To make it worth their while, survey subjects wanted 35 pounds a day. The boring person also was viewed as less competent, as is anyone with a boring job.

Now, there probably aren’t a lot of religious data analysts out there, but don’t worry, there are plenty of other boring jobs – accounting, tax/insurance, cleaning, and banking rounded out the top five (apparently people don’t like finances) – and hobbies – watching TV, observing animals, and mathematics filled out the top five. In case you’re curious, performing artists, scientists, journalists, health professionals, and teachers were viewed as having exciting jobs; exciting hobbies included gaming, reading, domestic tasks (really?), gardening, and writing.

Lead researcher Wijnand Van Tilburg, PhD, made an excellent point about people with boring jobs: They “have power in society – perhaps we should try not to upset them and stereotype them as boring!”

We think they should lean into it and make The Most Boring Man in the World ads: “When I drive a car off the lot, its value increases because I used the correct lending association. Batman trusts me with his Batmobile insurance. I can make those Cuban cigars tax exempt. Stay financially solvent, my friends.”
 

Fungi, but make it fashion

Fashion is an expensive and costly industry to sustain. Cotton production takes a toll on the environment, leather production comes with environmental and ethical/moral conundrums, and thanks to fast fashion, about 85% of textiles are being thrown away in the United States.

Researchers at the University of Borås in Sweden, however, have found a newish solution to create leather, cotton, and other textiles. And as with so many of the finer things, it starts with unsold bread from the grocery store.

Akram Zamani, PhD, and her team take that bread and turn it into breadcrumbs, then combine it with water and Rhizopus delemar, a fungus typically found in decaying food. After a couple of days of feasting on the bread, the fungus produces natural fibers made of chitin and chitosan that accumulate in the cell walls. After proteins, lipids, and other byproducts are removed, the team is left with a jelly-like substance made of those fibrous cell walls that can be spun into a fabric.

The researchers started small with very thin nonpliable sheets, but with a little layering by using tree tannins for softness and alkali for strength, their fungal leather is more like real leather than competing fungal leathers. Not to mention its being able to be produced in a fraction of the time.

This new fungal leather is fast to produce, it’s biodegradable, and it uses only natural ingredients to treat the materials. It’s the ultimate environmental fashion statement.
 

Who’s afraid of cancer? Not C. elegans

And now, we bring you part 2 of our ongoing series: Creatures that can diagnose cancer. Last week, we discovered that ants are well on their way to replacing dogs in our medical labs and in our hearts. This week, we present the even-more-lovable nematode.

The soil-dwelling nematode Caenorhabditis elegans, which is less than 1 mm long, is known to be “attracted or repelled by certain odors, so we came up with an idea that the roundworm could be used to detect lung cancer,” Shin Sik Choi, PhD, of Myongji University in South Korea, who is the project’s principal investigator, said in a statement on Eurekalert.

Dr. Choi’s team created a “worm-on-a-chip” that allowed the nematodes to choose between a drop of culture media from lung cancer cells and media from normal lung fibroblasts. An hour after being placed in the chip’s central chamber, more nematodes had crawled toward the lung cancer media than the normal-cell sample.

The investigators estimate that the device is about 70% effective at detecting cancer cells, but “they hope to increase both the accuracy and sensitivity of the method by using worms that were previously exposed to cancer cell media and therefore have a ‘memory’ of cancer-specific odor molecules,” according to the statement from the American Chemical Society.

Since C. elegans is easy to grow in a lab and, apparently, easy to train, the researchers hope that the worm-on-a-chip can become a quick, easy, economical, and noninvasive cancer screen.

So watch out cancer, because we never bet against the creepy crawlies.
 

Mosquitoes have us figured out

We are nearing mosquito season; quite possibly the most annoying and itchy time of the year. We stock up on bottles of bug spray, but somehow we still get bite after bite. It appears that mosquitoes are basically able to ignore our bug sprays, which explains why we’re still covered in bites after the Fourth of July fireworks. It turns out mosquitoes are more complex than we thought for such tiny creatures.

There’s plenty of research on the best ways to keep mosquitoes away, because not only are they incredibly annoying, but they also carry potentially harmful diseases. In a recent experiment, researchers used mosquitoes that were genetically modified to have an excessive amount of an odor receptor called AgOR2, which responds to the smell of humans.

“AgOR2 overexpression threw a wrench in the whole system by inactivating olfactory receptors in these mosquitoes,” Christopher Potter, PhD, associate professor of neuroscience at Johns Hopkins University, said in a written statement.

After testing how these genetically modified mosquitoes reacted to some of the common smells of bug spray such as lemongrass, they discovered that it’s easy for the mosquitoes to ignore the smell. We wish it were that easy for us to ignore that chemically fruity smell.

Researchers continue to work hard to figure out how to repel mosquitoes and we’re rooting for them as summer approaches, despite the mosquito’s status as a creepy crawly.

Can you keep it down? I’m trying to be boring

He chides his friends for not looking both ways before crossing the road. He is never questioned by the police because they fall asleep listening to him talk. He has won the office’s coveted perfect attendance award 10 years running. Look out, Dos Equis guy, you’ve got some new competition. That’s right, it’s the most boring man in the world.

For this boring study (sorry, study on boredom) conducted by English researchers and published in Personality and Social Psychology Bulletin, people were surveyed on various jobs and hobbies, ranking them by how exciting or boring they are, as well as how competent someone with those jobs/hobbies would be, their willingness to avoid someone with those jobs/hobbies, and how much they’d need to be paid to spend time with someone who had an undesirable job/hobby.

According to the British public, the most boring person in the world is a religious data analyst who likes to sleep and lives in a small town. In fact, spending time with this person is almost a full-time job on its own: To make it worth their while, survey subjects wanted 35 pounds a day. The boring person also was viewed as less competent, as is anyone with a boring job.

Now, there probably aren’t a lot of religious data analysts out there, but don’t worry, there are plenty of other boring jobs – accounting, tax/insurance, cleaning, and banking rounded out the top five (apparently people don’t like finances) – and hobbies – watching TV, observing animals, and mathematics filled out the top five. In case you’re curious, performing artists, scientists, journalists, health professionals, and teachers were viewed as having exciting jobs; exciting hobbies included gaming, reading, domestic tasks (really?), gardening, and writing.

Lead researcher Wijnand Van Tilburg, PhD, made an excellent point about people with boring jobs: They “have power in society – perhaps we should try not to upset them and stereotype them as boring!”

We think they should lean into it and make The Most Boring Man in the World ads: “When I drive a car off the lot, its value increases because I used the correct lending association. Batman trusts me with his Batmobile insurance. I can make those Cuban cigars tax exempt. Stay financially solvent, my friends.”
 

Fungi, but make it fashion

Fashion is an expensive and costly industry to sustain. Cotton production takes a toll on the environment, leather production comes with environmental and ethical/moral conundrums, and thanks to fast fashion, about 85% of textiles are being thrown away in the United States.

Researchers at the University of Borås in Sweden, however, have found a newish solution to create leather, cotton, and other textiles. And as with so many of the finer things, it starts with unsold bread from the grocery store.

Akram Zamani, PhD, and her team take that bread and turn it into breadcrumbs, then combine it with water and Rhizopus delemar, a fungus typically found in decaying food. After a couple of days of feasting on the bread, the fungus produces natural fibers made of chitin and chitosan that accumulate in the cell walls. After proteins, lipids, and other byproducts are removed, the team is left with a jelly-like substance made of those fibrous cell walls that can be spun into a fabric.

The researchers started small with very thin nonpliable sheets, but with a little layering by using tree tannins for softness and alkali for strength, their fungal leather is more like real leather than competing fungal leathers.

Among Black and White children, higher socioeconomic status (SES) was associated with lower pediatric postoperative mortality, according to a cohort study published in JAMA Network Open. However, this association was not equitable when comparing Black and White children.

The results showed that postoperative mortality rates were significantly higher in Black children in the highest income category, compared with White children in the same category.

“[We] assessed whether increasing family SES is associated with lower pediatric postoperative mortality and, if so, whether this association is equitable among Black and White children,” Brittany L. Willer, MD, of Nationwide Children’s Hospital in Columbus, Ohio, and colleagues wrote.

The researchers retrospectively analyzed data from 51 pediatric tertiary care hospitals apart of the Children’s Hospital Association Pediatric Health Information System. The cohort included children younger than 18 years who underwent inpatient surgical procedures between January 2004 and December 2020.

The exposures of interest were race and parental income quartile; the primary endpoint was risk-adjusted in-hospital mortality rates by race and parental income quartile.
 

Results

The study cohort included 1,378,111 participants, including 248,464 (18.0%) Black and 1,129,647 (82.0%) White children, respectively.

The overall mortality rate was 1.2%, and rates decreased as income quartile increased (1.4% in quartile 1 [lowest income]; 1.3% in quartile 2; 1.0% in quartile 3; and 0.9% in quartile 4 [highest income]; P < .001).

Among participants in the three lowest income quartiles, Black children had 33% greater odds of postoperative death versus White children (adjusted odds ratio, 1.33; 95% confidence interval, 1.27-1.39; P < .001). This difference persisted in children in the highest income quartile (aOR, 1.39; 95% CI, 1.25-1.54; P < .001).

In addition, postoperative mortality rates in Black children in the highest income quartile (1.30%; 95% CI, 1.19%-1.42%) were similar to those of White children in the lowest income quartile (1.20%; 95% CI, 1.16%-1.25%).

“These findings suggest that increasing family SES did not provide equitable advantage to Black, compared with White children, and interventions that target socioeconomic inequities alone may not fully address persistent racial disparities in pediatric postoperative mortality,” wrote Dr. Willer and colleagues. “A multifaceted approach that includes dismantling of socioeconomic barriers, equitable availability of comprehensive pediatric surgical care, and personalized care for children of all races is needed.”

The researchers acknowledged that a potential limitation of the study was the use of zip code–level median household income as a proxy for family SES.
 

A perspective

In an interview, Timothy Joos, MD, a Seattle internist and pediatrician in private practice, said “there is a fair dose of racism and classism inside all of us – recognizing and coming to terms with it are steps toward improving equity issues.

“As providers, we have to remind ourselves to give our most prompt and thorough care to the patients with the most acute and severe illnesses,” Dr. Joos said. “As organizations, we have to pursue feedback from all our clients, but with special outreach to those that are used to not having their voices heard.”

No funding sources were reported. The authors reported no relevant disclosures. Dr. Joos is a member of the Pediatric News editorial advisory board but had no other disclosures.

The pediatric oncology unit in Kyiv’s National Cancer Institute is empty, with all the children evacuated to safer hospitals in Western Ukraine or further, making it a good place to talk on Zoom.

Against a backdrop of colorful animals painted on the wall, Oleksandr Stakhovskyi, MD, PhD, speaks optimistically about the future of his city, his country, and even his patients, despite acknowledging that his surgical hands are now trained to use a machine gun.

“It’s not as bad as last week,” he laughs, explaining that residents of Kyiv are more relaxed now, despite the air raid sirens, because the city’s anti-missile system has thus far kept them safe.

Even still, missiles have continued hitting civilian residences and Dr. Stakhovskyi, a urologic-oncology surgeon, has evacuated his wife and children out of the country, as have 70% of his colleagues. But for those who stayed in Kyiv, there is a strong resolve.

“People working in IT, in law, in other professions — they just took the guns and stayed in Kyiv,” he said in an interview. “They are just civilians, armed, trying to protect and fortify Kyiv — to make it unbreakable.”

Dr. Stakhovskyi doesn’t have a background in the military, but he now knows how to use a machine gun. “I am a super-specialized oncologist, [but] I realize if I leave right now it will give the Russians momentum to come in. The longer it takes, the weaker the opponent army will become, and we are more and more optimistic,” he said.

In Kyiv, Dr. Stakhovskyi is working half the time at the cancer hospital and the other half at the nearby military hospital, but he said so far war casualties are minimal within the city, and even the flow of patients with cancer has reduced.

“I had my surgeries planned up until the end of March, but when the war started, they were all postponed,” he said. Emergency cancer surgeries have continued, and now there is talk of resuming some others. “We will stratify patients into categories based on need,” he said. “For those patients whose surgery can basically stop the disease and they don’t need neoadjuvant chemo, we’ll probably be doing those.”

Medical oncology clinics have also resumed, said Dr. Stakhovskyi, but the volume of patients is low, because many have left the city. An estimated 3.3 million people have left Ukraine since the Russian invasion on February 24.

Across the country, in Lviv near the Polish border, another surgical oncologist tells a different story. Andriy Hrynkiv, MD, from Lviv Regional Cancer Center, says his hospital has seen a dramatic increase in patients, displaced internally from areas where the medical infrastructure has collapsed.

“Russian forces have destroyed more than 117 hospitals, 43 ambulances have been shot at, 6 doctors have been killed, and 13 wounded,” Dr. Hrynkiv said. In the city of Mariupol, “doctors and patients have been taken hostage,” he said, used by Russian forces as a human shield. In Kharkiv, with approximately 1.5 million residents, the only oncologic hospital has been destroyed.

There is a shortage and instability of medical supplies including all iodine-containing medications that citizens are stocking up on in the face of a potential nuclear attack, he said.

Dr. Hrynkiv was speaking on a webcast organized by the American Society of Clinical Oncology (ASCO) and European Cancer Organisation (ECO).

The two organizations are collaborating with each other and the World Health Organization to create a special network that is aiming to connect professionals, academic and clinical centers, and patient groups.

Additionally, the Ukranian Society of Clinical Oncology (USCO), cofounded by Dr. Stakhovskyi, is trying to keep patients connected with nongovernment organizations.

“These patient organizations moved west when the war started, but they still use us to help them make contact with foreign doctors,” he said. “We have tried to centralize this process but it’s very difficult because patients and organizations are also calling doctors and centers directly looking for treatment options.”

He says USCO is also coordinating the distribution of a donation of immunotherapy pembrolizumab (Keytruda) from pharmaceutical company Merck Sharp & Dohme. “It’s a huge influx of this drug,” he says. “They’ve promised something like 2,000 doses to cover 230 patients for 3 months at least. Usually this is not an easy drug to access for people in Ukraine because it’s really expensive.”

Dr. Stakhovskyi said the optimism he feels is fueled by the support that Ukrainians feel from the rest of the world.

“We see the reaction of our international colleagues. It is so impressive and touching — lots of my ex-professors are texting me and sending me messages from all over the place, from Germany, from Canada, from France, from the United States,” he said. “And if we can be optimistic for ourselves, definitely that translates to our patients.”

Dr. Hrynkiv was speaking on a webcast organized by the American Society of Clinical Oncology (ASCO) and European Cancer Organisation (ECO).

The two organizations are collaborating with each other and the World Health Organization to create a special network that is aiming to connect professionals, academic and clinical centers, and patient groups.

Additionally, the Ukranian Society of Clinical Oncology (USCO), cofounded by Dr. Stakhovskyi, is trying to keep patients connected with nongovernment organizations.

“These patient organizations moved west when the war started, but they still use us to help them make contact with foreign doctors,” he said. “We have tried to centralize this process but it’s very difficult because patients and organizations are also calling doctors and centers directly looking for treatment options.”

He says USCO is also coordinating the distribution of a donation of immunotherapy pembrolizumab (Keytruda) from pharmaceutical company Merck Sharp & Dohme. “It’s a huge influx of this drug,” he says. “They’ve promised something like 2,000 doses to cover 230 patients for 3 months at least. Usually this is not an easy drug to access for people in Ukraine because it’s really expensive.”

Dr. Stakhovskyi said the optimism he feels is fueled by the support that Ukrainians feel from the rest of the world.

“We see the reaction of our international colleagues. It is so impressive and touching — lots of my ex-professors are texting me and sending me messages from all over the place, from Germany, from Canada, from France, from the United States,” he said. “And if we can be optimistic for ourselves, definitely that translates to our patients.”

The pediatric oncology unit in Kyiv’s National Cancer Institute is empty, with all the children evacuated to safer hospitals in Western Ukraine or further, making it a good place to talk on Zoom.

Against a backdrop of colorful animals painted on the wall, Oleksandr Stakhovskyi, MD, PhD, speaks optimistically about the future of his city, his country, and even his patients, despite acknowledging that his surgical hands are now trained to use a machine gun.

“It’s not as bad as last week,” he laughs, explaining that residents of Kyiv are more relaxed now, despite the air raid sirens, because the city’s anti-missile system has thus far kept them safe.

Even still, missiles have continued hitting civilian residences and Dr. Stakhovskyi, a urologic-oncology surgeon, has evacuated his wife and children out of the country, as have 70% of his colleagues. But for those who stayed in Kyiv, there is a strong resolve.

“People working in IT, in law, in other professions — they just took the guns and stayed in Kyiv,” he said in an interview. “They are just civilians, armed, trying to protect and fortify Kyiv — to make it unbreakable.”

Dr. Stakhovskyi doesn’t have a background in the military, but he now knows how to use a machine gun. “I am a super-specialized oncologist, [but] I realize if I leave right now it will give the Russians momentum to come in. The longer it takes, the weaker the opponent army will become, and we are more and more optimistic,” he said.

In Kyiv, Dr. Stakhovskyi is working half the time at the cancer hospital and the other half at the nearby military hospital, but he said so far war casualties are minimal within the city, and even the flow of patients with cancer has reduced.

“I had my surgeries planned up until the end of March, but when the war started, they were all postponed,” he said. Emergency cancer surgeries have continued, and now there is talk of resuming some others. “We will stratify patients into categories based on need,” he said. “For those patients whose surgery can basically stop the disease and they don’t need neoadjuvant chemo, we’ll probably be doing those.”

Medical oncology clinics have also resumed, said Dr. Stakhovskyi, but the volume of patients is low, because many have left the city. An estimated 3.3 million people have left Ukraine since the Russian invasion on February 24.

Across the country, in Lviv near the Polish border, another surgical oncologist tells a different story. Andriy Hrynkiv, MD, from Lviv Regional Cancer Center, says his hospital has seen a dramatic increase in patients, displaced internally from areas where the medical infrastructure has collapsed.

“Russian forces have destroyed more than 117 hospitals, 43 ambulances have been shot at, 6 doctors have been killed, and 13 wounded,” Dr. Hrynkiv said. In the city of Mariupol, “doctors and patients have been taken hostage,” he said, used by Russian forces as a human shield. In Kharkiv, with approximately 1.5 million residents, the only oncologic hospital has been destroyed.

There is a shortage and instability of medical supplies including all iodine-containing medications that citizens are stocking up on in the face of a potential nuclear attack, he said.

While several health care professionals can perform some of the same functions as physicians, at the end of the day, they are not MDs or DOs, nor do they have the education and training to earn the right to present themselves to patients as such. That’s the reasoning behind Senate Bill 239, recently signed into law by Indiana Gov. Eric J. Holcomb.

“It’s about transparency. Health care professionals at every level should be proud of their profession and want to help patients make an informed choice when seeking out options for treatment,” Carrie Davis, MD, a Bloomington, Ind.–based dermatologist and member of the Indiana State Medical Association’s commission on legislation, told this news organization. “When this law goes into effect, a patient will be able to seek that treatment with confidence knowing they can trust the education, training, and license of the health care expert they’ve chosen to see.”

The patient safety measure, which will take effect on July 1, specifically prohibits the misappropriation of medical specialty titles such as anesthesiologist, cardiologist, dermatologist, and others by professionals who have not graduated from medical school and completed the necessary training to adopt the physician title. It also prohibits health care professionals from using deceptive or misleading advertising that misrepresents or falsely describes their profession, education, or skills.

“Using the medical term ‘anesthesiologist’ for nurse anesthetists, confuses patients who deserve to be fully informed of their health care provider’s qualifications,” Randall M. Clark, MD, president of the American Society of Anesthesiologists (ASA), said in a statement. “This new law affirms the most fundamental right of patients to know the qualifications of their health care professional.”
 

What’s in a title?

The problem stretches far beyond professional turf battles, as patients are often confused about the differences between various types of health care providers, according to the American Medical Association’s Truth in Advertising Campaign. Often, patients mistakenly believe they are meeting with medical doctors or doctors of osteopathic medicine when they are not.

Seung Sim, MD, an Indiana anesthesiologist and the immediate past president of the Indiana Society of Anesthesiologists, said in an interview that every member of the medical team plays an important role in high-quality patient care, but among that team, education and training differs.

“The threat to patient safety comes by nonphysicians marketing themselves in a way that is confusing to patients, and misleading, making the patient believe they’re seeing a physician when they’re not,” said Dr. Sim. “That patient deserves to know who is providing their health care and what level of education and training they have, so the patient can make the best decision for their treatment.”
 

Medical groups speak out

Several professional medical groups have voiced their opposition to medical title misappropriation.

Perhaps most notably, the ASA has been spearheading efforts that prohibit medical professionals to identify as physicians for several years. In 2019, the ASA authored Resolution 228, which calls on the AMA to oppose and work with state medical societies to prevent the misappropriation of medical specialties’ titles.

The resolution, which was adopted by the AMA in June 2019, also reaffirms support of the Scope of Practice Partnership’s Truth in Advertising Campaign to ensure patients receive accurate information about who is providing their care.

In addition, in 2021, the ASA condemned the decision by the American Association of Nurse Anesthetists to change its name to the American Association of Nurse Anesthesiology (AANA) – pointing out that the term “nurse anesthesiologist” could confuse patients and create discord in the care setting, ultimately risking patient safety.

While the ASA and other professional groups support team-based models of care, they are quick to point out that health care professionals need to know their place in the lineup.

A statement from the American Osteopathic Association (AOA), for instance, points out that only DOs and MDs can be licensed to practice medicine – and, therefore, “physician-led” should not mean “physician-optional.” In fact, only professionals who have earned the right to practice medicine through completion of medical school and accredited residency/fellowship training and who have achieved board certification in their chosen specialty/subspecialty should take the helm of these multidisciplinary teams, according to the AOA.

The AANA cast the controversy in a completely different light, characterizing its name change as part of a rebranding effort to advance the science of nurse anesthesiology and advocate for certified registered nurse anesthetists. In 2021, the AANA asserted: “The notion of being pushed by the American Society of Anesthesiologists that rebranding and changing the name of the AANA will somehow mislead or harm patients or create discord among providers is absurd at best and false and inflammatory fearmongering at worst.”

The American College of Cardiology has issued an expert consensus clinical guidance document for the evaluation and management of adults with key cardiovascular consequences of COVID-19.

The document makes recommendations on how to evaluate and manage COVID-associated myocarditis and long COVID and gives advice on resumption of exercise following COVID-19 infection.

The clinical guidance was published online March 16 in the Journal of the American College of Cardiology.

“The best means to diagnose and treat myocarditis and long COVID following SARS-CoV-2 infection continues to evolve,” said Ty Gluckman, MD, MHA, cochair of the expert consensus decision pathway. “This document attempts to provide key recommendations for how to evaluate and manage adults with these conditions, including guidance for safe return to play for both competitive and noncompetitive athletes.”

The authors of the guidance note that COVID-19 can be associated with various abnormalities in cardiac testing and a wide range of cardiovascular complications. For some patients, cardiac symptoms such as chest pain, shortness of breath, fatigue, and palpitations persist, lasting months after the initial illness, and evidence of myocardial injury has also been observed in both symptomatic and asymptomatic individuals, as well as after receipt of the COVID-19 mRNA vaccine. 

“For clinicians treating these individuals, a growing number of questions exist related to evaluation and management of these conditions, as well as safe resumption of physical activity,” they say. This report is intended to provide practical guidance on these issues.
 

Myocarditis

The report states that myocarditis has been recognized as a rare but serious complication of SARS-CoV-2 infection as well as COVID-19 mRNA vaccination.

It defines myocarditis as: 1.cardiac symptoms such as chest pain, dyspnea, palpitations, or syncope; 2. elevated cardiac troponin; and 3. abnormal electrocardiographic, echocardiographic, cardiac MRI, and/or histopathologic findings on biopsy.

The document makes the following recommendations in regard to COVID-related myocarditis:

When there is increased suspicion for cardiac involvement with COVID-19, initial testing should consist of an ECG, measurement of cardiac troponin, and an echocardiogram. Cardiology consultation is recommended for those with a rising cardiac troponin and/or echocardiographic abnormalities. Cardiac MRI is recommended in hemodynamically stable patients with suspected myocarditis.

Hospitalization is recommended for patients with definite myocarditis, ideally at an advanced heart failure center. Patients with fulminant myocarditis should be managed at centers with an expertise in advanced heart failure, mechanical circulatory support, and other advanced therapies.

Patients with myocarditis and COVID-19 pneumonia (with an ongoing need for supplemental oxygen) should be treated with corticosteroids. For patients with suspected pericardial involvement, treatment with NSAIDs, colchicine, and/or prednisone is reasonable. Intravenous corticosteroids may be considered in those with suspected or confirmed COVID-19 myocarditis with hemodynamic compromise or MIS-A (multisystem inflammatory syndrome in adults). Empiric use of corticosteroids may also be considered in those with biopsy evidence of severe myocardial infiltrates or fulminant myocarditis, balanced against infection risk.

As appropriate, guideline-directed medical therapy for heart failure should be initiated and continued after discharge.

The document notes that myocarditis following COVID-19 mRNA vaccination is rare, with highest rates seen in young males after the second vaccine dose. As of May 22, 2021, the U.S. Vaccine Adverse Event Reporting System noted rates of 40.6 cases per million after the second vaccine dose among male individuals aged 12-29 years and 2.4 cases per million among male individuals aged 30 and older. Corresponding rates in female individuals were 4.2 and 1 cases per million, respectively.

But the report says that COVID-19 vaccination is associated with “a very favorable benefit-to-risk ratio” for all age and sex groups evaluated thus far.

In general, vaccine-associated myocarditis should be diagnosed, categorized, and treated in a manner analogous to myocarditis following SARS-CoV-2 infection, the guidance advises.
 

Long COVID

The document refers to long COVID as postacute sequelae of SARS-CoV-2 infection (PASC), and reports that this condition is experienced by up to 10%-30% of infected individuals. It is defined by a constellation of new, returning, or persistent health problems experienced by individuals 4 or more weeks after COVID-19 infection.

Although individuals with this condition may experience wide-ranging symptoms, the symptoms that draw increased attention to the cardiovascular system include tachycardia, exercise intolerance, chest pain, and shortness of breath.

Nicole Bhave, MD, cochair of the expert consensus decision pathway, says: “There appears to be a ‘downward spiral’ for long-COVID patients. Fatigue and decreased exercise capacity lead to diminished activity and bed rest, in turn leading to worsening symptoms and decreased quality of life.” She adds that “the writing committee recommends a basic cardiopulmonary evaluation performed up front to determine if further specialty care and formalized medical therapy is needed for these patients.”

The authors propose two terms to better understand potential etiologies for those with cardiovascular symptoms:

PASC-CVD, or PASC-cardiovascular disease, refers to a broad group of cardiovascular conditions (including myocarditis) that manifest at least 4 weeks after COVID-19 infection.

PASC-CVS, or PASC-cardiovascular syndrome, includes a wide range of cardiovascular symptoms without objective evidence of cardiovascular disease following standard diagnostic testing.

The document makes the following recommendations for the management of PASC-CVD and PASC-CVS.

For patients with cardiovascular symptoms and suspected PASC, the authors suggest that a reasonable initial testing approach includes basic laboratory testing, including cardiac troponin, an ECG, an echocardiogram, an ambulatory rhythm monitor, chest imaging, and/or pulmonary function tests.

Cardiology consultation is recommended for patients with PASC who have abnormal cardiac test results, known cardiovascular disease with new or worsening symptoms, documented cardiac complications during SARS-CoV-2 infection, and/or persistent cardiopulmonary symptoms that are not otherwise explained.

Recumbent or semirecumbent exercise (for example, rowing, swimming, or cycling) is recommended initially for PASC-CVS patients with tachycardia, exercise/orthostatic intolerance, and/or deconditioning, with transition to upright exercise as orthostatic intolerance improves. Exercise duration should also be short (5-10 minutes/day) initially, with gradual increases as functional capacity improves.

Salt and fluid loading represent nonpharmacologic interventions that may provide symptomatic relief for patients with tachycardia, palpitations, and/or orthostatic hypotension.

Beta-blockers, nondihydropyridine calcium-channel blockers, ivabradine, fludrocortisone, and midodrine may be used empirically as well.
 

Return to play for athletes

The authors note that concerns about possible cardiac injury after COVID-19 fueled early apprehension regarding the safety of competitive sports for athletes recovering from the infection.

But they say that subsequent data from large registries have demonstrated an overall low prevalence of clinical myocarditis, without a rise in the rate of adverse cardiac events. Based on this, updated guidance is provided with a practical, evidence-based framework to guide resumption of athletics and intense exercise training.

They make the following recommendations:

• For athletes recovering from COVID-19 with ongoing cardiopulmonary symptoms (chest pain, shortness of breath, palpitations, lightheadedness) or those requiring hospitalization with increased suspicion for cardiac involvement, further evaluation with triad testing – an ECG, measurement of cardiac troponin, and an echocardiogram – should be performed.
• For those with abnormal test results, further evaluation with cardiac MRI should be considered. Individuals diagnosed with clinical myocarditis should abstain from exercise for 3-6 months.
• Cardiac testing is not recommended for asymptomatic individuals following COVID-19 infection. Individuals should abstain from training for 3 days to ensure that symptoms do not develop.
• For those with mild or moderate noncardiopulmonary symptoms (fever, lethargy, muscle aches), training may resume after symptom resolution.
• For those with remote infection (≥3 months) without ongoing cardiopulmonary symptoms, a gradual increase in exercise is recommended without the need for cardiac testing.

Based on the low prevalence of myocarditis observed in competitive athletes with COVID-19, the authors note that these recommendations can be reasonably applied to high-school athletes (aged 14 and older) along with adult recreational exercise enthusiasts.

Future study is needed, however, to better understand how long cardiac abnormalities persist following COVID-19 infection and the role of exercise training in long COVID.

The authors conclude that the current guidance is intended to help clinicians understand not only when testing may be warranted, but also when it is not.

“Given that it reflects the current state of knowledge through early 2022, it is anticipated that recommendations will change over time as our understanding evolves,” they say.

The 2022 ACC Expert Consensus Decision Pathway on Cardiovascular Sequelae of COVID-19: Myocarditis, Post-Acute Sequelae of SARS-CoV-2 Infection (PASC), and Return to Play will be discussed in a session at the American College of Cardiology’s annual scientific session meeting in Washington in April.

Recumbent or semirecumbent exercise (for example, rowing, swimming, or cycling) is recommended initially for PASC-CVS patients with tachycardia, exercise/orthostatic intolerance, and/or deconditioning, with transition to upright exercise as orthostatic intolerance improves. Exercise duration should also be short (5-10 minutes/day) initially, with gradual increases as functional capacity improves.

Salt and fluid loading represent nonpharmacologic interventions that may provide symptomatic relief for patients with tachycardia, palpitations, and/or orthostatic hypotension.

Beta-blockers, nondihydropyridine calcium-channel blockers, ivabradine, fludrocortisone, and midodrine may be used empirically as well.
 

Return to play for athletes

The authors note that concerns about possible cardiac injury after COVID-19 fueled early apprehension regarding the safety of competitive sports for athletes recovering from the infection.

But they say that subsequent data from large registries have demonstrated an overall low prevalence of clinical myocarditis, without a rise in the rate of adverse cardiac events. Based on this, updated guidance is provided with a practical, evidence-based framework to guide resumption of athletics and intense exercise training.

They make the following recommendations:

• For athletes recovering from COVID-19 with ongoing cardiopulmonary symptoms (chest pain, shortness of breath, palpitations, lightheadedness) or those requiring hospitalization with increased suspicion for cardiac involvement, further evaluation with triad testing – an ECG, measurement of cardiac troponin, and an echocardiogram – should be performed.
• For those with abnormal test results, further evaluation with cardiac MRI should be considered. Individuals diagnosed with clinical myocarditis should abstain from exercise for 3-6 months.
• Cardiac testing is not recommended for asymptomatic individuals following COVID-19 infection. Individuals should abstain from training for 3 days to ensure that symptoms do not develop.
• For those with mild or moderate noncardiopulmonary symptoms (fever, lethargy, muscle aches), training may resume after symptom resolution.
• For those with remote infection (≥3 months) without ongoing cardiopulmonary symptoms, a gradual increase in exercise is recommended without the need for cardiac testing.

Based on the low prevalence of myocarditis observed in competitive athletes with COVID-19, the authors note that these recommendations can be reasonably applied to high-school athletes (aged 14 and older) along with adult recreational exercise enthusiasts.

Future study is needed, however, to better understand how long cardiac abnormalities persist following COVID-19 infection and the role of exercise training in long COVID.

The authors conclude that the current guidance is intended to help clinicians understand not only when testing may be warranted, but also when it is not.

“Given that it reflects the current state of knowledge through early 2022, it is anticipated that recommendations will change over time as our understanding evolves,” they say.

The 2022 ACC Expert Consensus Decision Pathway on Cardiovascular Sequelae of COVID-19: Myocarditis, Post-Acute Sequelae of SARS-CoV-2 Infection (PASC), and Return to Play will be discussed in a session at the American College of Cardiology’s annual scientific session meeting in Washington in April.

The American College of Cardiology has issued an expert consensus clinical guidance document for the evaluation and management of adults with key cardiovascular consequences of COVID-19.

The document makes recommendations on how to evaluate and manage COVID-associated myocarditis and long COVID and gives advice on resumption of exercise following COVID-19 infection.

The clinical guidance was published online March 16 in the Journal of the American College of Cardiology.

“The best means to diagnose and treat myocarditis and long COVID following SARS-CoV-2 infection continues to evolve,” said Ty Gluckman, MD, MHA, cochair of the expert consensus decision pathway. “This document attempts to provide key recommendations for how to evaluate and manage adults with these conditions, including guidance for safe return to play for both competitive and noncompetitive athletes.”

The authors of the guidance note that COVID-19 can be associated with various abnormalities in cardiac testing and a wide range of cardiovascular complications. For some patients, cardiac symptoms such as chest pain, shortness of breath, fatigue, and palpitations persist, lasting months after the initial illness, and evidence of myocardial injury has also been observed in both symptomatic and asymptomatic individuals, as well as after receipt of the COVID-19 mRNA vaccine. 

“For clinicians treating these individuals, a growing number of questions exist related to evaluation and management of these conditions, as well as safe resumption of physical activity,” they say. This report is intended to provide practical guidance on these issues.
 

Myocarditis

The report states that myocarditis has been recognized as a rare but serious complication of SARS-CoV-2 infection as well as COVID-19 mRNA vaccination.

It defines myocarditis as: 1.cardiac symptoms such as chest pain, dyspnea, palpitations, or syncope; 2. elevated cardiac troponin; and 3. abnormal electrocardiographic, echocardiographic, cardiac MRI, and/or histopathologic findings on biopsy.

The document makes the following recommendations in regard to COVID-related myocarditis:

When there is increased suspicion for cardiac involvement with COVID-19, initial testing should consist of an ECG, measurement of cardiac troponin, and an echocardiogram. Cardiology consultation is recommended for those with a rising cardiac troponin and/or echocardiographic abnormalities. Cardiac MRI is recommended in hemodynamically stable patients with suspected myocarditis.

Hospitalization is recommended for patients with definite myocarditis, ideally at an advanced heart failure center. Patients with fulminant myocarditis should be managed at centers with an expertise in advanced heart failure, mechanical circulatory support, and other advanced therapies.

Patients with myocarditis and COVID-19 pneumonia (with an ongoing need for supplemental oxygen) should be treated with corticosteroids. For patients with suspected pericardial involvement, treatment with NSAIDs, colchicine, and/or prednisone is reasonable. Intravenous corticosteroids may be considered in those with suspected or confirmed COVID-19 myocarditis with hemodynamic compromise or MIS-A (multisystem inflammatory syndrome in adults). Empiric use of corticosteroids may also be considered in those with biopsy evidence of severe myocardial infiltrates or fulminant myocarditis, balanced against infection risk.

As appropriate, guideline-directed medical therapy for heart failure should be initiated and continued after discharge.

The document notes that myocarditis following COVID-19 mRNA vaccination is rare, with highest rates seen in young males after the second vaccine dose. As of May 22, 2021, the U.S. Vaccine Adverse Event Reporting System noted rates of 40.6 cases per million after the second vaccine dose among male individuals aged 12-29 years and 2.4 cases per million among male individuals aged 30 and older. Corresponding rates in female individuals were 4.2 and 1 cases per million, respectively.

But the report says that COVID-19 vaccination is associated with “a very favorable benefit-to-risk ratio” for all age and sex groups evaluated thus far.

In general, vaccine-associated myocarditis should be diagnosed, categorized, and treated in a manner analogous to myocarditis following SARS-CoV-2 infection, the guidance advises.
 

Long COVID

The document refers to long COVID as postacute sequelae of SARS-CoV-2 infection (PASC), and reports that this condition is experienced by up to 10%-30% of infected individuals. It is defined by a constellation of new, returning, or persistent health problems experienced by individuals 4 or more weeks after COVID-19 infection.

Although individuals with this condition may experience wide-ranging symptoms, the symptoms that draw increased attention to the cardiovascular system include tachycardia, exercise intolerance, chest pain, and shortness of breath.

Nicole Bhave, MD, cochair of the expert consensus decision pathway, says: “There appears to be a ‘downward spiral’ for long-COVID patients. Fatigue and decreased exercise capacity lead to diminished activity and bed rest, in turn leading to worsening symptoms and decreased quality of life.” She adds that “the writing committee recommends a basic cardiopulmonary evaluation performed up front to determine if further specialty care and formalized medical therapy is needed for these patients.”

The authors propose two terms to better understand potential etiologies for those with cardiovascular symptoms:

PASC-CVD, or PASC-cardiovascular disease, refers to a broad group of cardiovascular conditions (including myocarditis) that manifest at least 4 weeks after COVID-19 infection.

PASC-CVS, or PASC-cardiovascular syndrome, includes a wide range of cardiovascular symptoms without objective evidence of cardiovascular disease following standard diagnostic testing.

The document makes the following recommendations for the management of PASC-CVD and PASC-CVS.

For patients with cardiovascular symptoms and suspected PASC, the authors suggest that a reasonable initial testing approach includes basic laboratory testing, including cardiac troponin, an ECG, an echocardiogram, an ambulatory rhythm monitor, chest imaging, and/or pulmonary function tests.

Cardiology consultation is recommended for patients with PASC who have abnormal cardiac test results, known cardiovascular disease with new or worsening symptoms, documented cardiac complications during SARS-CoV-2 infection, and/or persistent cardiopulmonary symptoms that are not otherwise explained.

Recumbent or semirecumbent exercise (for example, rowing, swimming, or cycling) is recommended initially for PASC-CVS patients with tachycardia, exercise/orthostatic intolerance, and/or deconditioning, with transition to upright exercise as orthostatic intolerance improves. Exercise duration should also be short (5-10 minutes/day) initially, with gradual increases as functional capacity improves.

Salt and fluid loading represent nonpharmacologic interventions that may provide symptomatic relief for patients with tachycardia, palpitations, and/or orthostatic hypotension.

Beta-blockers, nondihydropyridine calcium-channel blockers, ivabradine, fludrocortisone, and midodrine may be used empirically as well.

The oncologist’s new best friend

We know that dogs have very sensitive noses. They can track criminals and missing persons and sniff out drugs and bombs. They can even detect cancer cells … after months of training.

And then there are ants.

Erik Karits/Pixabay

Cancer cells produce volatile organic compounds (VOCs), which can be sniffed out by dogs and other animals with sufficiently sophisticated olfactory senses. A group of French investigators decided to find out if Formica fusca is such an animal.

First, they placed breast cancer cells and healthy cells in a petri dish. The sample of cancer cells, however, included a sugary treat. “Over successive trials, the ants got quicker and quicker at finding the treat, indicating that they had learned to recognize the VOCs produced by the cancerous cells, using these as a beacon to guide their way to the sugary delight,” according to IFL Science.

When the researchers removed the treat, the ants still went straight for the cancer cells. Then they removed the healthy cells and substituted another type of breast cancer cell, with just one type getting the treat. They went for the cancer cells with the treat, “indicating that they were capable of distinguishing between the different cancer types based on the unique pattern of VOCs emitted by each one,” IFL Science explained.

It’s just another chapter in the eternal struggle between dogs and ants. Dogs need months of training to learn to detect cancer cells; ants can do it in 30 minutes. Over the course of a dog’s training, Fido eats more food than 10,000 ants combined. (Okay, we’re guessing here, but it’s got to be a pretty big number, right?)

Then there’s the warm and fuzzy factor. Just look at that picture. Who wouldn’t want a cutie like that curling up in the bed next to you?
 

Console War II: Battle of the Twitter users

Video games can be a lot of fun, provided you’re not playing something like Rock Simulator. Or Surgeon Simulator. Or Surgeon Simulator 2. Yes, those are all real games. But calling yourself a video gamer invites a certain negative connotation, and nowhere can that be better exemplified than the increasingly ridiculous console war.

Comstock/Thinkstock

For those who don’t know their video game history, back in the early 90s Nintendo and Sega were the main video game console makers. Nintendo had Mario, Sega had Sonic, and everyone had an opinion on which was best. With Sega now but a shell of its former self and Nintendo viewed as too “casual” for the true gaming connoisseur, today’s battle pits Playstation against Xbox, and fans of both consoles spend their time trying to one-up each other in increasingly silly online arguments.

That brings us nicely to a Twitter user named “Shreeveera,” who is very vocal about his love of Playstation and hatred of the Xbox. Importantly, for LOTME purposes, Shreeveera identified himself as a doctor on his profile, and in the middle of an argument, Xbox enthusiasts called his credentials into question.

At this point, most people would recognize that there are very few noteworthy console-exclusive video games in today’s world and that any argument about consoles essentially comes down to which console design you like or which company you find less distasteful, and they would step away from the Twitter argument. Shreeveera is not most people, and he decided the next logical move was to post a video of himself and an anesthetized patient about to undergo a laparoscopic cholecystectomy.

This move did prove that he was indeed a doctor, but the ethics of posting such a video with a patient in the room is a bit dubious at best. Since Shreeveera also listed the hospital he worked at, numerous Twitter users review bombed the hospital with one-star reviews. Shreeveera’s fate is unknown, but he did take down the video and removed “doctor by profession” from his profile. He also made a second video asking Twitter to stop trying to ruin his life. We’re sure that’ll go well. Twitter is known for being completely fair and reasonable.
 

Use your words to gain power

We live in the age of the emoji. The use of emojis in texts and emails is basically the new shorthand. It’s a fun and easy way to chat with people close to us, but a new study shows that it doesn’t help in a business setting. In fact, it may do a little damage.

Gordon Johnson/Pixabay

The use of images such as emojis in communication or logos can make a person seem less powerful than someone who opts for written words, according to Elinor Amit, PhD, of Tel Aviv University and associates.

Participants in their study were asked to imagine shopping with a person wearing a T-shirt. Half were then shown the logo of the Red Sox baseball team and half saw the words “Red Sox.” In another scenario, they were asked to imagine attending a retreat of a company called Lotus. Then half were shown an employee wearing a shirt with an image of lotus flower and half saw the verbal logo “Lotus.” In both scenarios, the individuals wearing shirts with images were seen as less powerful than the people who wore shirts with words on them.

Why is that? In a Eurekalert statement, Dr. Amit said that “visual messages are often interpreted as a signal for desire for social proximity.” In a world with COVID-19, that could give anyone pause.

That desire for more social proximity, in turn, equals a suggested loss of power because research shows that people who want to be around other people more are less powerful than people who don’t.

With the reduced social proximity we have these days, we may want to keep things cool and lighthearted, especially in work emails with people who we’ve never met. It may be, however, that using your words to say thank you in the multitude of emails you respond to on a regular basis is better than that thumbs-up emoji. Nobody will think less of you.
 

Should Daylight Savings Time still be a thing?

This past week, we just experienced the spring-forward portion of Daylight Savings Time, which took an hour of sleep away from us all. Some of us may still be struggling to find our footing with the time change, but at least it’s still sunny out at 7 pm. For those who don’t really see the point of changing the clocks twice a year, there are actually some good reasons to do so.

mohamed hassan/PxHere

Sen. Marco Rubio, sponsor of a bill to make the time change permanent, put it simply: “If we can get this passed, we don’t have to do this stupidity anymore.” Message received, apparently, since the measure just passed unanimously in the Senate.

It’s not clear if President Biden will approve it, though, because there’s a lot that comes into play: economic needs, seasonal depression, and safety.

“I know this is not the most important issue confronting America, but it’s one of those issues where there’s a lot of agreement,” Sen. Rubio said.

Not total agreement, though. The National Association of Convenience Stores is opposed to the bill, and Reuters noted that one witness at a recent hearing said the time change “is like living in the wrong time zone for almost eight months out of the year.”

Many people, however, seem to be leaning toward the permanent spring-forward as it gives businesses a longer window to provide entertainment in the evenings and kids are able to play outside longer after school.

Honestly, we’re leaning toward whichever one can reduce seasonal depression.

The genetically altered pig’s heart “worked like a rock star, beautifully functioning,” the surgeon who performed the pioneering Jan. 7 xenotransplant procedure said in a press statement on the death of the patient, David Bennett Sr.

“He wasn’t able to overcome what turned out to be devastating – the debilitation from his previous period of heart failure, which was extreme,” said Bartley P. Griffith, MD, clinical director of the cardiac xenotransplantation program at the University of Maryland, Baltimore.

University of Maryland Medical Center

Representatives of the institution aren’t offering many details on the cause of Mr. Bennett’s death on March 8, 60 days after his operation, but said they will elaborate when their findings are formally published. But their comments seem to downplay the unique nature of the implanted heart itself as a culprit and instead implicate the patient’s diminished overall clinical condition and what grew into an ongoing battle with infections.

The 57-year-old Bennett, bedridden with end-stage heart failure, judged a poor candidate for a ventricular assist device, and on extracorporeal membrane oxygenation (ECMO), reportedly was offered the extraordinary surgery after being turned down for a conventional transplant at several major centers.

“Until day 45 or 50, he was doing very well,” Muhammad M. Mohiuddin, MD, the xenotransplantation program’s scientific director, observed in the statement. But infections soon took advantage of his hobbled immune system.

Given his “preexisting condition and how frail his body was,” Dr. Mohiuddin said, “we were having difficulty maintaining a balance between his immunosuppression and controlling his infection.” Mr. Bennett went into multiple organ failure and “I think that resulted in his passing away.”


 

Beyond wildest dreams

The surgeons confidently framed Mr. Bennett’s experience as a milestone for heart xenotransplantation. “The demonstration that it was possible, beyond the wildest dreams of most people in the field, even, at this point – that we were able to take a genetically engineered organ and watch it function flawlessly for 9 weeks – is pretty positive in terms of the potential of this therapy,” Dr. Griffith said.

But enough questions linger that others were more circumspect, even as they praised the accomplishment. “There’s no question that this is a historic event,” Mandeep R. Mehra, MD, of Harvard Medical School, and director of the Center for Advanced Heart Disease at Brigham and Women’s Hospital, both in Boston, said in an interview.

Still, “I don’t think we should just conclude that it was the patient’s frailty or death from infection,” Dr. Mehra said. With so few details available, “I would be very careful in prematurely concluding that the problem did not reside with the heart but with the patient. We cannot be sure.”

For example, he noted, “6 to 8 weeks is right around the time when some cardiac complications, like accelerated forms of vasculopathy, could become evident.” Immune-mediated cardiac allograft vasculopathy is a common cause of heart transplant failure.

Or, “it could as easily have been the fact that immunosuppression was modified at 6 to 7 weeks in response to potential infection, which could have led to a cardiac compromise,” Dr. Mehra said. “We just don’t know.”

“It’s really important that this be reported in a scientifically accurate way, because we will all learn from this,” Lori J. West, MD, DPhil, said in an interview.

Little seems to be known for sure about the actual cause of death, “but the fact there was not hyperacute rejection is itself a big step forward. And we know, at least from the limited information we have, that it did not occur,” observed Dr. West, who directs the Alberta Transplant Institute, Edmonton, and the Canadian Donation and Transplantation Research Program. She is a professor of pediatrics with adjunct positions in the departments of surgery and microbiology/immunology.

Dr. West also sees Mr. Bennett’s struggle with infections and adjustments to his unique immunosuppressive regimen, at least as characterized by his care team, as in line with the experience of many heart transplant recipients facing the same threat.

“We already walk this tightrope with every transplant patient,” she said. Typically, they’re put on a somewhat standardized immunosuppressant regimen, “and then we modify it a bit, either increasing or decreasing it, depending on the posttransplant course.” The regimen can become especially intense in response to new signs of rejection, “and you know that that’s going to have an impact on susceptibility to all kinds of infections.”
 

Full circle

The porcine heart was protected along two fronts against assault from Mr. Bennett’s immune system and other inhospitable aspects of his physiology, either of which could also have been obstacles to success: Genetic modification (Revivicor) of the pig that provided the heart, and a singularly aggressive antirejection drug regimen for the patient.

The knockout of three genes targeting specific porcine cell-surface carbohydrates that provoke a strong human antibody response reportedly averted a hyperacute rejection response that would have caused the graft to fail almost immediately.

Other genetic manipulations, some using CRISPR technology, silenced genes encoded for porcine endogenous retroviruses. Others were aimed at controlling myocardial growth and stemming graft microangiopathy.  

Mr. Bennett himself was treated with powerful immunosuppressants, including an investigational anti-CD40 monoclonal antibody (KPL-404, Kiniksa Pharmaceuticals) that, according to UMSOM, inhibits a well-recognized pathway critical to B-cell proliferation, T-cell activation, and antibody production.

“I suspect the patient may not have had rejection, but unfortunately, that intense immunosuppression really set him up – even if he had been half that age – for a very difficult time,” David A. Baran, MD, a cardiologist from Sentara Advanced Heart Failure Center, Norfolk, Va., who studies transplant immunology, said in an interview.

“This is in some ways like the original heart transplant in 1967, when the ability to do the surgery evolved before understanding of the immunosuppression needed. Four or 5 years later, heart transplantation almost died out, before the development of better immunosuppressants like cyclosporine and later tacrolimus,” Dr. Baran said.

“The current age, when we use less immunosuppression than ever, is based on 30 years of progressive success,” he noted. This landmark xenotransplantation “basically turns back the clock to a time when the intensity of immunosuppression by definition had to be extremely high, because we really didn’t know what to expect.”
 

Emerging role of xeno-organs

Xenotransplantation has been touted as potential strategy for expanding the pool of organs available for transplantation. Mr. Bennett’s “breakthrough surgery” takes the world “one step closer to solving the organ shortage crisis,” his surgeon, Dr. Griffith, announced soon after the procedure. “There are simply not enough donor human hearts available to meet the long list of potential recipients.”

But it’s not the only proposed approach. Measures could be taken, for example, to make more efficient use of the human organs that become available, partly by opening the field to additional less-than-ideal hearts and loosening regulatory mandates for projected graft survival.

“Every year, more than two-thirds of donor organs in the United States are discarded. So it’s not actually that we don’t have enough organs, it’s that we don’t have enough organs that people are willing to take,” Dr. Baran said. Still, it’s important to pursue all promising avenues, and “the genetic manipulation pathway is remarkable.”

But “honestly, organs such as kidneys probably make the most sense” for early study of xenotransplantation from pigs, he said. “The waiting list for kidneys is also very long, but if the kidney graft were to fail, the patient wouldn’t die. It would allow us to work out the immunosuppression without putting patients’ lives at risk.”

Often overlooked in assessments of organ demand, Dr. West said, is that “a lot of patients who could benefit from a transplant will never even be listed for a transplant.” It’s not clear why; perhaps they have multiple comorbidities, live too far from a transplant center, “or they’re too big or too small. Even if there were unlimited organs, you could never meet the needs of people who could benefit from transplantation.”

So even if more available donor organs were used, she said, there would still be a gap that xenotransplantation could help fill. “I’m very much in favor of research that allows us to continue to try to find a pathway to xenotransplantation. I think it’s critically important.”

Unquestionably, “we now need to have a dialogue to entertain how a technology like this, using modern medicine with gene editing, is really going to be utilized,” Dr. Mehra said. The Bennett case “does open up the field, but it also raises caution.” There should be broad participation to move the field forward, “coordinated through either societies or nationally allocated advisory committees that oversee the movement of this technology, to the next step.”

Ideally, that next step “would be to do a safety clinical trial in the right patient,” he said. “And the right patient, by definition, would be one who does not have a life-prolonging option, either mechanical circulatory support or allograft transplantation. That would be the goal.”

Dr. Mehra has reported receiving payments to his institution from Abbott for consulting; consulting fees from Janssen, Mesoblast, Broadview Ventures, Natera, Paragonix, Moderna, and the Baim Institute for Clinical Research; and serving on a scientific advisory board NuPulseCV, Leviticus, and FineHeart. Dr. Baran disclosed consulting for Getinge and LivaNova; speaking for Pfizer; and serving on trial steering committees for CareDx and Procyrion, all unrelated to xenotransplantation. Dr. West has declared no relevant conflicts.

The genetically altered pig’s heart “worked like a rock star, beautifully functioning,” the surgeon who performed the pioneering Jan. 7 xenotransplant procedure said in a press statement on the death of the patient, David Bennett Sr.

“He wasn’t able to overcome what turned out to be devastating – the debilitation from his previous period of heart failure, which was extreme,” said Bartley P. Griffith, MD, clinical director of the cardiac xenotransplantation program at the University of Maryland, Baltimore.

Representatives of the institution aren’t offering many details on the cause of Mr. Bennett’s death on March 8, 60 days after his operation, but said they will elaborate when their findings are formally published. But their comments seem to downplay the unique nature of the implanted heart itself as a culprit and instead implicate the patient’s diminished overall clinical condition and what grew into an ongoing battle with infections.

The 57-year-old Bennett, bedridden with end-stage heart failure, judged a poor candidate for a ventricular assist device, and on extracorporeal membrane oxygenation (ECMO), reportedly was offered the extraordinary surgery after being turned down for a conventional transplant at several major centers.
