MDedge Surgery

The heart from a genetically modified pig transplanted to a Maryland patient in January in a pioneering, acclaimed, and widely critiqued surgery appears to have carried an unwanted passenger.

A porcine cytomegalovirus (PCMV) in the heart had gone undetected before the operation and may or may not have been instrumental in David Bennett’s death 2 months later, according to a report published in MIT Technology Review.

“The issue is now a subject of wide discussion among specialists, who think the infection was a potential contributor to Mr. Bennett’s death and a possible reason why the heart did not last longer,” states the article, written by staff journalist Antonio Regalado.

As described in the story, the xenotransplant saga’s new twist comes from the surgeon who performed the operation, Bartley P. Griffith, MD, University of Maryland, Baltimore, who related the PCMV finding in an April 20 online presentation hosted by the American Society of Transplantation.

Mr. Bennett’s initially promising but later turbulent clinical course, described by his surgeons and widely reported upon his death, included repeated skirmishes with infection and retaliatory adjustments to his immunosuppressant regimen. Those episodes were thought to have contributed to his death, the actual cause of which is undetermined or at least not yet reported.

“We are beginning to learn why he passed on,” Dr. Griffith said in Mr. Regalado’s article, acknowledging further that the porcine virus “maybe was the actor, or could be the actor,” that set off the events leading to Bennett’s death.

Xenotransplant specialists know that PCMV is a potential problem with pig organs and know to test for it before attempting the procedure in animal models, notes the article. It refers to a published series of pig-heart transplants to baboons in Germany. The hearts “lasted only a couple of weeks if the virus was present, while organs free from the infection could survive more than half a year.”

The heart Mr. Bennett received had been extensively screened for bacteria, viruses, and other issues that could have threatened the organ and Mr. Bennett, but the effort apparently fell short. In the MIT Technology Review story, the first author of the German baboon series speculates on how the University of Maryland team might have missed PCMV.

“The U.S. team appears to have tested the pig’s snout for the virus, but often it is lurking deeper in the tissues,” Joachim Denner, PhD, Institute of Virology, Free University of Berlin, said in the article. The virus, he contended, “can be detected and easily removed from pig populations, but unfortunately they didn’t use a good assay and didn’t detect the virus.”

That PCMV escaped detection before the operation “could now factor into some people’s questions over whether the experiment should have taken place at all,” the MIT Technology Review article proposes. “It’s a big red flag,” bioethicist Arthur Caplan, PhD, New York University, said in a quote, adding: “If doctors can’t prevent or control infection, ‘then such experiments are tough to justify.’ ”

Anyone who practices Mohs micrographic surgery is likely to know the name Hugh Greenway, MD, the longtime head of Mohs and dermatologic surgery at Scripps Clinic in San Diego, who was also recently selected as program director for cutaneous oncology at Scripps MD Anderson Cancer Center in San Diego. He is also a former president of the American College of Mohs Surgery.

After earning his medical degree from the Medical College of Georgia, Augusta, in 1974, Dr. Greenway was fellowship trained in Mohs skin cancer surgery by Frederic E. Mohs, MD, at the University of Wisconsin–Madison. He completed his dermatology residency at the Naval Medical Center San Diego and joined Scripps Clinic in 1983, where he launched the institution’s first Mohs surgery program, as well as a popular annual intensive course in superficial anatomy and cutaneous surgery that bears his name. He was also the first physician in the world to use interferon as a nonsurgical treatment of basal cell carcinoma.

To date, Dr. Greenway has performed more than 41,000 Mohs surgery cases and has trained 61 fellows who practice in academic and clinical settings. In 2017, he received the Frederic E. Mohs Award from the ACMS at the college’s annual meeting. He is also a past CEO of Scripps Clinic. In this Q&A, Dr. Greenway opens up about what it was like to train with Dr. Mohs, what makes a good Mohs surgeon, and why he’s excited about the future of dermatology.
 

I understand that you first became interested in a medical career after meeting Dr. Carl Jones, a friend of your father who was your Scoutmaster in the Boy Scouts in Georgia. What about Dr. Jones inspired you to pursue a career in medicine?

Dr. Jones was an internist/allergist in Atlanta, where I grew up. His three sons and I were friends. My dad had dealt with several medical problems being injured in World War II and subsequently undergoing a couple of kidney transplantations, so I developed an interest in medicine personally. Even though Dr. Jones was a specialist, he started out as a family doctor like I did, so he was interested in the whole person and all of his or her medical problems as opposed to those related to his specialty only. I traveled with the Boy Scouts to camp at places like Valley Forge in Pennsylvania, and Dr. Jones was involved with the medical set-ups of those large events. That also contributed to my interest in medicine.

As part of your 9-year service in the U.S. Navy, you spent 2 years as the flight surgeon at NAS Atlanta/Dobbins Air Force Base. What was your most memorable experience from that assignment?

Dobbins is a large facility with two Lockheed plants, and the Air Force had built the medical clinic, which was staffed by the Navy. Getting to know some of the active-duty members of the Air Force, the Navy, and the National Guard, and their commitment to our country, was memorable. Jimmy Carter was the president in those days. When he would fly in Dobbins, one of my jobs as the flight surgeon was to be on base when Air Force One landed or departed. One night, we had a DC-9 commercial aircraft coming from Huntsville, Ala., to Atlanta that got caught in a thunderstorm a little above 30,000 feet. Both engines went out and the aircraft essentially became a glider. The pilots tried to land on our runway but unfortunately, they ended up 4 miles short. We were heavily involved in responding to the crash, which was a tragic event. I also learned to fly (second seat) different types of aircraft during my assignment at NAS Atlanta/Dobbins Air Force Base, everything from the large C-5s to Navy fighter jets and helicopters. Coincidentally, Dr. Jones was involved with a couple of free health clinics in Atlanta when I was stationed there. Every Tuesday night, my wife (who is a nurse) and I would volunteer at a clinic in Cabbagetown, which was one of the poorer areas of Atlanta. It was a chance to give back to a group of people who didn’t have a whole lot.

In the middle your dermatology residency at Naval Medical Center San Diego, you were selected by Dr. Mohs for fellowship training in Mohs skin cancer surgery at the University of Wisconsin–Madison. What do you remember most about your training with Dr. Mohs?

Dr. Mohs was a kind, humble man who had this great idea about skin cancer. He was not a dermatologist; he was a general surgeon. The technique he developed was originally called chemosurgery because he put a chemical onto the skin. This was known as the fixed-tissue technique. Then we had a fresh-tissue technique, where we did not use the chemical, but we were able to use local anesthesia right away. That developed into the Mohs surgery we know today. Dr. Mohs did not name it that; he was very humble, but he was very proud of his technique. He was also a very hard worker. On the first day of my fellowship, I started at 7 in the morning and ended at 7 at night. It was the same for the last day of my fellowship. He also had an excellent office staff, many of whom had worked with him for many years. Patients with difficult skin cancers traveled to Madison from all over the world because there weren’t that many Mohs surgery clinics in those days. During the latter part of my fellowship, Michael McCall, MD, and I had the opportunity to remove a skin cancer from the nose of Dr. Mohs. We presented the case at a national conference, and I titled the talk “Mohs Surgery for Mohs’ Nose.”

Early in your career Dr. Mohs asked you to take over his practice, but you accepted an offer to establish the first Mohs surgery office at Scripps in San Diego instead. What convinced you to head West?

After my fellowship, I returned to San Diego to complete my residency with the Navy, where we opened a Mohs surgery clinic. Dr. Mohs came out for the ribbon cutting. During that time, I was taking care of several patients that he had treated in Wisconsin. Through that my wife and I ended up going to dinner with Cecil and Ida Green, philanthropists who made several financial gifts to Scripps Clinic – and for whom Scripps Green Hospital is named. Cecil cofounded Texas Instruments and was knighted by Queen Elizabeth. During dinner, he suggested that I stay in San Diego for a year and work at Scripps after my residency assignment with the Navy. I agreed and have been here ever since.

What do you find most interesting about Mohs surgery?

In Mohs surgery, you’re able to provide not only surgical care to eliminate the tumor, but also the pathology and the reconstruction. That was interesting to me. Dr. Mohs was not that interested in reconstruction. He was more focused on the tumor, in part because with the original fixed-tissue technique you could not do the reconstruction. You had to wait for an extra layer of tissue to separate. But with the fresh-tissue technique, you were able to provide the reconstruction that day. Mohs surgery deals with a subset of tumors that are challenging to treat. That also spiked my academic and clinical interest.

In your opinion, what’s been the most important advance in Mohs surgery to date?

In recent years, immunology has come into play, so now we have teams of clinicians in dermatology, medical oncology, surgery, and other subspecialties providing patients the best of care. In the arena of Mohs surgery itself, in the 1980s, the American College of Mohs Surgery developed a 1-year fellowship program, which enabled us to train many men and women to practice Mohs surgery. Most of them are dermatologists.

Please complete the sentence: “You can tell a good Mohs surgeon by the way he/she ...”

Treats patients, is willing to spend time with them, and shows an interest in them. One of the things we should strive for is to let patients know that they as a person are important; it’s not just the melanoma on their nose. We’re not only dealing with a skin cancer; we’re dealing with a patient who has skin cancer.

For the past 39 years, you have led Hugh Greenway’s Superficial Anatomy and Cutaneous Surgery course, which takes place every January in San Diego. What’s been key to sustaining this training course for nearly 4 decades?

There have been many people involved in its success, so it’s not just me. When I first started my practice, there really was not a focus on anatomy in the general dermatologic community. Dermatologic surgery textbooks contained very little content on surgical anatomy so I developed an interest a putting together a course that would cover some of this material. I met with Terence Davidson, MD, an otolaryngologist who was dean of continuing medical education at the University of California, San Diego. The course includes lectures from experts in many subspecialties and hands-on laboratories using cadavers to work on anatomy and surgical techniques. After about 16 years of doing the course Dr. Davidson told me: “When we started this course, as a group, the head and neck surgeons were the best to do the reconstructions on the face with skin flaps and grafts and layered closures. But now, as a group, the dermatologists are best at doing that.” That’s what we want to hear in medical education.

During the peak of the COVID-19 pandemic, what were your most significant challenges from both a clinical and a personal standpoint?

I’m fortunate to practice at a place like Scripps, where there are many resources to look at what was happening with COVID-19. Clinically, we had to put a lot of things on hold, but we tried our best to keep our cancer patients in particular in the forefront of care. It has been a challenge, but fortunately we have been able to take care of patients after a brief timeout. Many of us remember the polio vaccine back in the 1950s. Having worked overseas and at missionary hospital where we had children die of measles because they were not vaccinated gave me a larger appreciation for the importance of vaccines. I recommend all young physicians who work with me to read, “The Great Influenza: The Story of the Deadliest Pandemic in History,” by John M. Barry, which recounts the 1918 flu epidemic.

Who inspires you most in your work today?

I don’t view what I do as work. Dr. Jones and Dr. Mohs continue to inspire me with what they accomplished during their careers. You have to love people and love patients. Every patient who comes to see me has a story, so I try to understand their story. One of the things I really enjoy is training the young fellows. We train three Mohs fellows per year at Scripps, and it’s a great challenge every day.

What development in dermatology are you most excited about in the next 5 years?

Dermatology will continue to evolve just like all other medical specialties. We’re going to see a large growth in telemedicine, and immunotherapy is playing a key role in dermatologic oncology. What excites me the most in medicine is the young people who enter the field willing to contribute their lives to helping others.

Then we had a fresh-tissue technique, where we did not use the chemical, but we were able to use local anesthesia right away. That developed into the Mohs surgery we know today. Dr. Mohs did not name it that; he was very humble, but he was very proud of his technique. He was also a very hard worker. On the first day of my fellowship, I started at 7 in the morning and ended at 7 at night. It was the same for the last day of my fellowship. He also had an excellent office staff, many of whom had worked with him for many years. Patients with difficult skin cancers traveled to Madison from all over the world because there weren’t that many Mohs surgery clinics in those days. During the latter part of my fellowship, Michael McCall, MD, and I had the opportunity to remove a skin cancer from the nose of Dr. Mohs. We presented the case at a national conference, and I titled the talk “Mohs Surgery for Mohs’ Nose.”

Early in your career Dr. Mohs asked you to take over his practice, but you accepted an offer to establish the first Mohs surgery office at Scripps in San Diego instead. What convinced you to head West?

After my fellowship, I returned to San Diego to complete my residency with the Navy, where we opened a Mohs surgery clinic. Dr. Mohs came out for the ribbon cutting. During that time, I was taking care of several patients that he had treated in Wisconsin. Through that my wife and I ended up going to dinner with Cecil and Ida Green, philanthropists who made several financial gifts to Scripps Clinic – and for whom Scripps Green Hospital is named. Cecil cofounded Texas Instruments and was knighted by Queen Elizabeth. During dinner, he suggested that I stay in San Diego for a year and work at Scripps after my residency assignment with the Navy. I agreed and have been here ever since.

What do you find most interesting about Mohs surgery?

In Mohs surgery, you’re able to provide not only surgical care to eliminate the tumor, but also the pathology and the reconstruction. That was interesting to me. Dr. Mohs was not that interested in reconstruction. He was more focused on the tumor, in part because with the original fixed-tissue technique you could not do the reconstruction. You had to wait for an extra layer of tissue to separate. But with the fresh-tissue technique, you were able to provide the reconstruction that day. Mohs surgery deals with a subset of tumors that are challenging to treat. That also spiked my academic and clinical interest.

In your opinion, what’s been the most important advance in Mohs surgery to date?

In recent years, immunology has come into play, so now we have teams of clinicians in dermatology, medical oncology, surgery, and other subspecialties providing patients the best of care. In the arena of Mohs surgery itself, in the 1980s, the American College of Mohs Surgery developed a 1-year fellowship program, which enabled us to train many men and women to practice Mohs surgery. Most of them are dermatologists.

Please complete the sentence: “You can tell a good Mohs surgeon by the way he/she ...”

Treats patients, is willing to spend time with them, and shows an interest in them. One of the things we should strive for is to let patients know that they as a person are important; it’s not just the melanoma on their nose. We’re not only dealing with a skin cancer; we’re dealing with a patient who has skin cancer.

For the past 39 years, you have led Hugh Greenway’s Superficial Anatomy and Cutaneous Surgery course, which takes place every January in San Diego. What’s been key to sustaining this training course for nearly 4 decades?

There have been many people involved in its success, so it’s not just me. When I first started my practice, there really was not a focus on anatomy in the general dermatologic community. Dermatologic surgery textbooks contained very little content on surgical anatomy so I developed an interest a putting together a course that would cover some of this material. I met with Terence Davidson, MD, an otolaryngologist who was dean of continuing medical education at the University of California, San Diego. The course includes lectures from experts in many subspecialties and hands-on laboratories using cadavers to work on anatomy and surgical techniques. After about 16 years of doing the course Dr. Davidson told me: “When we started this course, as a group, the head and neck surgeons were the best to do the reconstructions on the face with skin flaps and grafts and layered closures. But now, as a group, the dermatologists are best at doing that.” That’s what we want to hear in medical education.

During the peak of the COVID-19 pandemic, what were your most significant challenges from both a clinical and a personal standpoint?

I’m fortunate to practice at a place like Scripps, where there are many resources to look at what was happening with COVID-19. Clinically, we had to put a lot of things on hold, but we tried our best to keep our cancer patients in particular in the forefront of care. It has been a challenge, but fortunately we have been able to take care of patients after a brief timeout. Many of us remember the polio vaccine back in the 1950s. Having worked overseas and at missionary hospital where we had children die of measles because they were not vaccinated gave me a larger appreciation for the importance of vaccines. I recommend all young physicians who work with me to read, “The Great Influenza: The Story of the Deadliest Pandemic in History,” by John M. Barry, which recounts the 1918 flu epidemic.

Who inspires you most in your work today?

I don’t view what I do as work. Dr. Jones and Dr. Mohs continue to inspire me with what they accomplished during their careers. You have to love people and love patients. Every patient who comes to see me has a story, so I try to understand their story. One of the things I really enjoy is training the young fellows. We train three Mohs fellows per year at Scripps, and it’s a great challenge every day.

What development in dermatology are you most excited about in the next 5 years?

Dermatology will continue to evolve just like all other medical specialties. We’re going to see a large growth in telemedicine, and immunotherapy is playing a key role in dermatologic oncology. What excites me the most in medicine is the young people who enter the field willing to contribute their lives to helping others.

Fecal matter may be in the fountain of youth

Yes, you read that headline correctly. New research by scientists at Quadram Institute and the University of East Anglia, both in Norwich, England, supports the claim that transferring fecal microbes might actually have some positive effects on reversing the aging process in the eyes, brain, and gut.

How do they know? Mice, of course. In the study, scientists took the gut microbes from older mice and transferred them into the younger mince. The young mice displayed inflamed signs of aging in their guts, brains, and eyes, which, we all know, decline in function as we age. What happens is a chronic inflammation of cells as we get older that can be found in the brain or gut that leads to a degenerative state over time.

When the older mice received the gut microbes from younger mice, the investigators saw the reverse: Gut, brain, and eye functionality improved. In a way, minimizing the inflammation.

There’s tons of research out there that suggests gut health is the key to a healthy life, but this study points directly to an improvement in brain and vision functionality as a result of the transfer.

Now, we’re not insinuating you get a poo transfer as you reach old age. And the shift to human studies on microbiota replacement therapy is still in the works. But this definitely is a topic to watch and could be a game changer in the age-old quest to bottle youth or at least improve quality of life as we age.

For now, the scientists did find some connections between the beneficial bacteria in the transplants and the human diet that could have similar effects, like changes in the metabolism of certain fats and vitamin that could have effects on the inflammatory cells in the eye and brain.

It’s not lying, it’s preemptive truth

Lying is bad. Bold statement, we know, but a true one. After all, God spent an entire commandment telling people not to do the whole bearing false witness thing, and God is generally known for not joking around. He’s a pretty serious dude.

In case you’ve been wandering around the desert for a while and haven’t had wifi, we have a bit of a misinformation problem these days. People lie all the time about a lot of things, and a lot of people believe the lies. According to new research, however, there are also a lot of people who recognize the lies but accept them anyway because they believe that the lies will become true in the future.

Imagine the following scenario: A friend gets a job he’s not qualified for because he listed a skill he doesn’t have. That’s bad, right? And the people the researchers interviewed agreed, at least initially. But when informed that our friend is planning on obtaining the skill in summer classes in the near future, the study participants became far more willing to excuse the initial lie.

A friend jumping the gun on training he doesn’t have yet is fairly innocuous as far as lying goes, but as the researchers found, this willingness to forgive lies because they could become true extends far further. For example, millions of people do not vote illegally in U.S. elections, nor do White people get approved for mortgages at rates 300% higher than minorities, but when asked to imagine scenarios in which those statements could be true, study participants were less likely to condemn the lie and prevent it from spreading further, especially if their political viewpoints aligned with the respective falsehood.

It seems, then, that while we may aspire to not tell lies, we take after another guy with magic powers who spent too much time in the desert: “What I told you was true, from a certain point of view.”

LISBON – Screening for Staphylococcus aureus, decolonization, and use of teicoplanin for surgical antimicrobial prophylaxis among patients with methicillin-resistant S. aureus (MRSA) lowered the number of prosthetic joint infections in elderly patients undergoing surgery for fracture of the femur.

The findings were presented in a poster at the 32nd European Congress of Clinical Microbiology & Infectious Diseases (ECCMID) 2022, which was one of the few awarded the accolade of “top-rated poster.”

“We actually found that with our intervention, all prosthetic joint infections decreased, not just the Staphylococcus aureus but those due to MRSA, too,” Natividad Benito, MD, an infectious diseases specialist at Hospital de la Santa Creu i Sant Pau in Barcelona, said in an interview. “We’re pleased with these results because prosthetic joint infections present such a complicated situation for patients and surgeons. This is also a relatively easy intervention to use, and with time, even the PCR [polymerase chain reaction] technology will become cheaper. Now, in our hospital, prosthetic joint infections are rare.”

At Hospital de la Santa Creu i Sant Pau, around 200 hip hemiarthroplasties are performed per year. Preceding the intervention, the hospital recorded 11 prosthetic joint infections, with up to five infections due to S. aureus and up to four due to MRSA.

The intervention was introduced in 2016. After 2 years, there were no cases of prosthetic joint infections due to S. aureus; in 2018 there, was one case of prosthetic joint infection due to MRSA. In 2019, there was one case of prosthetic joint infection, but it was due neither to S. aureus nor MRSA. In 2020 and 2021, there was one infection each year that was due to MRSA.

Jesús Rodríguez Baño, MD, head of the infectious diseases division, Hospital Universitario Virgen Macarena at the University of Seville, Spain, who was not involved in the study, explained that for patients with hip fracture, “the time frame in which colonization can be studied is too short using traditional methods. Prosthetic joint infections in this population have a devastating effect, with not negligible mortality and very important morbidity and health care costs.”

Referring to the significant reduction in the rate of S. aureus prosthetic joint infections in the postintervention period, Dr. Rodríguez Baño said in an interview, “The results are sound, and the important reduction in infection risk invites for the development of a multicenter, randomized trial to confirm these interesting results.

“The authors are commended for measuring the impact of applying a well-justified preventive protocol,” Dr. Rodríguez Baño added. However, the study has some limitations: “It was performed in one center, it was not randomized, and control for potential confounders is needed.”
 

Decolonization in an emergency femur fracture

This study addressed a particular need in residents of Spain’s long-term care facilities. In 2016, the prevalence of MRSA was high.

Roughly one-third of the general population carry S. aureus in their noses. In care homes, the rate of MRSA is higher than in the general population, at around 30% of those with S. aureus. In Spain, recommendations for patients undergoing elective total joint arthroplasty advise S. aureus decolonization – which can take 5 days – to prevent surgical site infections.

“The problem with the elderly population is not only have they a higher incidence of MRSA but that the surgical prophylaxis is inadequate for MRSA,” Dr. Benito pointed out.

Many patients in long-term care facilities are elderly and frail and are at greater risk of fracture. Unlike elective hip surgery, in which patients are asked to undergo decolonization over the 5 days prior to their operation, with emergent femur fractures, there is insufficient time for such preparation. “These patients with femur fractures need surgery as soon as possible,” said Dr. Benito.

No studies have been conducted to determine the best way to minimize infection risk from S. aureus and MRSA for patients undergoing emergency hip hemiarthroplasty surgery to treat femoral fractures.

In the current study, Dr. Benito and coauthors assessed whether a bundle of measures – including rapid detection of S. aureus nasal carriage by PCR upon arrival in the emergency setting, followed by decolonization of carriers using a topical treatment in the nose and a prescription of surgical antimicrobial prophylaxis (adapted antibiotic prophylaxis for MRSA) – reduces the incidence of prosthetic joint infections after surgery.

The quasi-experimental single-center study included patients admitted to the emergency department at Hospital de la Santa Creu i Sant Pau. The PCR was rapid, with a turnaround of just 1.5 hours. Decolonization of S. aureus carriers was carried out using nasal mupirocin and chlorhexidine gluconate bathing, which was started immediately. It was used for a 5 days and was usually continued throughout and after surgery.

Patients carrying MRSA received teicoplanin as optimal surgical antimicrobial prophylaxis instead of cefazolin. The intervention did not interfere with the timing of surgery. The study’s principal outcomes were overall incidence of prosthetic joint infections and the incidence of those specifically caused by S. aureus and MRSA.

The researchers compared findings regarding these outcomes over 5 consecutive years of the intervention to outcomes during 4 consecutive years prior to the intervention, which started in 2016.

During 2016-2020, from 22% to 31% of the overall number of patients requiring hip hemiarthroplasty were referred from long-term care facilities. From 25% to 29% of these patients tested positive for S. aureus on PCR, and of these, 33%-64% had MRSA.

There were 772 surgical procedures from 2012 to 2015 and 786 from 2017 to 2020.

Prior to the intervention, over the years 2012-2014, S. aureus caused 36%-50% of prosthetic joint infections; 25%-100% of the S. aureus infections were MRSA. This decreased significantly after the intervention.

During 2016-2020, there was an average of 14 prosthetic joint infections (1.5%), compared to 36 (4.7%) in 2012-2015 (P < .001). Similarly, the incidence of prosthetic joint infections due to S. aureus dropped to 0.3% from 1.8% (P < .002). The incidence of MRSA prosthetic joint infections was 0.3% for 2016-2020, versus 1.2% for 2012-2015 (P = .012).

The years 2018, 2020, and 2021 each saw one case of infection due to MRSA. They were most likely due to “the intervention not being performed properly in all cases,” said Dr. Benito.

A prosthetic joint infection is very serious for the patient. “It means reoperating, because antibiotics are not enough to clear the infection. The biofilm and pus of the infection need to be cleaned out, a new prosthesis is needed, after which more antibiotics are needed for around 2 months, which can be hard to tolerate, and even then, the infection might not be eradicated,” explained Dr. Benito. “Many of these people are old and frail, and mortality can be significant. Getting a prosthetic joint infection is catastrophic for these patients.”

Dr. Benito and Dr. Rodríguez-Baño have disclosed no relevant financial relationships.

The findings were presented in a poster at the 32nd European Congress of Clinical Microbiology & Infectious Diseases (ECCMID) 2022, which was one of the few awarded the accolade of “top-rated poster.”

“We actually found that with our intervention, all prosthetic joint infections decreased, not just the Staphylococcus aureus but those due to MRSA, too,” Natividad Benito, MD, an infectious diseases specialist at Hospital de la Santa Creu i Sant Pau in Barcelona, said in an interview. “We’re pleased with these results because prosthetic joint infections present such a complicated situation for patients and surgeons. This is also a relatively easy intervention to use, and with time, even the PCR [polymerase chain reaction] technology will become cheaper. Now, in our hospital, prosthetic joint infections are rare.”

At Hospital de la Santa Creu i Sant Pau, around 200 hip hemiarthroplasties are performed per year. Preceding the intervention, the hospital recorded 11 prosthetic joint infections, with up to five infections due to S. aureus and up to four due to MRSA.

The intervention was introduced in 2016. After 2 years, there were no cases of prosthetic joint infections due to S. aureus; in 2018 there, was one case of prosthetic joint infection due to MRSA. In 2019, there was one case of prosthetic joint infection, but it was due neither to S. aureus nor MRSA. In 2020 and 2021, there was one infection each year that was due to MRSA.

Jesús Rodríguez Baño, MD, head of the infectious diseases division, Hospital Universitario Virgen Macarena at the University of Seville, Spain, who was not involved in the study, explained that for patients with hip fracture, “the time frame in which colonization can be studied is too short using traditional methods. Prosthetic joint infections in this population have a devastating effect, with not negligible mortality and very important morbidity and health care costs.”

Referring to the significant reduction in the rate of S. aureus prosthetic joint infections in the postintervention period, Dr. Rodríguez Baño said in an interview, “The results are sound, and the important reduction in infection risk invites for the development of a multicenter, randomized trial to confirm these interesting results.

“The authors are commended for measuring the impact of applying a well-justified preventive protocol,” Dr. Rodríguez Baño added. However, the study has some limitations: “It was performed in one center, it was not randomized, and control for potential confounders is needed.”
 

Decolonization in an emergency femur fracture

This study addressed a particular need in residents of Spain’s long-term care facilities. In 2016, the prevalence of MRSA was high.

Roughly one-third of the general population carry S. aureus in their noses. In care homes, the rate of MRSA is higher than in the general population, at around 30% of those with S. aureus. In Spain, recommendations for patients undergoing elective total joint arthroplasty advise S. aureus decolonization – which can take 5 days – to prevent surgical site infections.

“The problem with the elderly population is not only have they a higher incidence of MRSA but that the surgical prophylaxis is inadequate for MRSA,” Dr. Benito pointed out.

Many patients in long-term care facilities are elderly and frail and are at greater risk of fracture. Unlike elective hip surgery, in which patients are asked to undergo decolonization over the 5 days prior to their operation, with emergent femur fractures, there is insufficient time for such preparation. “These patients with femur fractures need surgery as soon as possible,” said Dr. Benito.

No studies have been conducted to determine the best way to minimize infection risk from S. aureus and MRSA for patients undergoing emergency hip hemiarthroplasty surgery to treat femoral fractures.

In the current study, Dr. Benito and coauthors assessed whether a bundle of measures – including rapid detection of S. aureus nasal carriage by PCR upon arrival in the emergency setting, followed by decolonization of carriers using a topical treatment in the nose and a prescription of surgical antimicrobial prophylaxis (adapted antibiotic prophylaxis for MRSA) – reduces the incidence of prosthetic joint infections after surgery.

The quasi-experimental single-center study included patients admitted to the emergency department at Hospital de la Santa Creu i Sant Pau. The PCR was rapid, with a turnaround of just 1.5 hours. Decolonization of S. aureus carriers was carried out using nasal mupirocin and chlorhexidine gluconate bathing, which was started immediately. It was used for a 5 days and was usually continued throughout and after surgery.

Patients carrying MRSA received teicoplanin as optimal surgical antimicrobial prophylaxis instead of cefazolin. The intervention did not interfere with the timing of surgery. The study’s principal outcomes were overall incidence of prosthetic joint infections and the incidence of those specifically caused by S. aureus and MRSA.

The researchers compared findings regarding these outcomes over 5 consecutive years of the intervention to outcomes during 4 consecutive years prior to the intervention, which started in 2016.

During 2016-2020, from 22% to 31% of the overall number of patients requiring hip hemiarthroplasty were referred from long-term care facilities. From 25% to 29% of these patients tested positive for S. aureus on PCR, and of these, 33%-64% had MRSA.

There were 772 surgical procedures from 2012 to 2015 and 786 from 2017 to 2020.

Prior to the intervention, over the years 2012-2014, S. aureus caused 36%-50% of prosthetic joint infections; 25%-100% of the S. aureus infections were MRSA. This decreased significantly after the intervention.

During 2016-2020, there was an average of 14 prosthetic joint infections (1.5%), compared to 36 (4.7%) in 2012-2015 (P < .001). Similarly, the incidence of prosthetic joint infections due to S. aureus dropped to 0.3% from 1.8% (P < .002). The incidence of MRSA prosthetic joint infections was 0.3% for 2016-2020, versus 1.2% for 2012-2015 (P = .012).

The years 2018, 2020, and 2021 each saw one case of infection due to MRSA. They were most likely due to “the intervention not being performed properly in all cases,” said Dr. Benito.

A prosthetic joint infection is very serious for the patient. “It means reoperating, because antibiotics are not enough to clear the infection. The biofilm and pus of the infection need to be cleaned out, a new prosthesis is needed, after which more antibiotics are needed for around 2 months, which can be hard to tolerate, and even then, the infection might not be eradicated,” explained Dr. Benito. “Many of these people are old and frail, and mortality can be significant. Getting a prosthetic joint infection is catastrophic for these patients.”

Dr. Benito and Dr. Rodríguez-Baño have disclosed no relevant financial relationships.

Knee and shoulder pain are common complaints for patients in the primary care office.

But identifying the source of the pain can be complicated,

and an accurate diagnosis of the underlying cause of discomfort is key to appropriate management – whether that involves simple home care options of ice and rest or a recommendation for a follow-up with a specialist.

Speaking at the annual meeting of the American College of Physicians, Greg Nakamoto, MD, department of orthopedics, Virginia Mason Medical Center, Seattle, discussed common knee and shoulder problems that patients often present with in the primary care setting, and offered tips on diagnosis and appropriate management.

The most common conditions causing knee pain are osteoarthritis and meniscal tears. “The differential for knee pain is broad,” Dr. Nakamoto said. “You have to have a way to divide it down, such as if it’s acute or chronic.”

The initial workup has several key components. The first steps: Determine the location of the pain – anterior, medial, lateral, posterior – and then whether it stems from an injury or is atraumatic.

“If you have to ask one question – ask where it hurts,” he said. “And is it from an injury or just wear and tear? That helps me when deciding if surgery is needed.”

Pain in the knee generally localizes well to the site of pathology, and knee pain of acute traumatic onset requires more scrutiny for problems best treated with early surgery. “This also helps establish whether radiographic findings are due to injury or degeneration,” Dr. Nakamoto said. “The presence of swelling guides the need for anti-inflammatories or cortisone.”

Palpating for tenderness along the joint line is important, as is palpating above and below the joint line, Dr. Nakamoto said.

“Tenderness limited to the joint line, combined with a meniscal exam maneuver that reproduces joint-line pain, is suggestive of pain from meniscal pathology,” he said.

Imaging is an important component of evaluating knee symptoms, and the question often arises as to when to order an MRI.

Dr. Nakamoto offered the following scenario: If significant osteoarthritis is evident on weight-bearing x-ray, treat the patient for the condition. However, if little or no osteoarthritis appears on x-ray, and if the onset of symptoms was traumatic and both patient history and physical examination suggest a meniscal tear, order an MRI.

An early MRI also is needed if the patient has had either atraumatic or traumatic onset of symptoms and their history and physical exams are suspicious for a mechanically locked or locking meniscus. For suspicion of a ruptured quadriceps or patellar tendon or a stress fracture, an MRI is needed urgently.

An MRI would be ordered later if the patient’s symptoms have not improved significantly after 3 months of conservative management.

Dr. Nakamoto stressed how common undiagnosed meniscus tears are in the general population. A third of men aged 50-59 years and nearly 20% of women in that age group have a tear, he said. “That number goes up to 56% and 51% in men and women aged 70-90 years, and 61% of these tears were in patients who were asymptomatic in the last month.”

In the setting of osteoarthritis, 76% of asymptomatic patients had a meniscus tear, and 91% of patients with symptomatic osteoarthritis had a meniscus tear, he added.

Treating knee pain

Treatment will vary depending on the underlying etiology of pain. For a possible meniscus tear, the recommendation is for a conservative intervention with ice, ibuprofen, knee immobilizer, and crutches, with a follow-up appointment in a week.

Three types of injections also can help:

• Cortisone for osteoarthritis or meniscus tears, swelling, and inflammation, and prophylaxis against inflammation.
• Viscosupplementation (intra‐articular hyaluronic acid) for chronic, baseline osteoarthritis symptoms.
• Regenerative therapies (platelet-rich plasma, stem cells, etc.) are used primarily for osteoarthritis (these do not regrow cartilage, but some patients report decreased pain).

The data on injections are mixed, Dr. Nakamoto said. For example, the results of a 2015 Cochrane review on cortisone injections for osteoarthritis reported that the benefits were small to moderate at 4‐6 weeks, and small to none at 13 weeks.  

“There is a lot of controversy for viscosupplementation despite all of the data on it,” he said. “But the recommendations from professional organizations are mixed.”

He noted that he has been using viscosupplementation since the 1990s, and some patients do benefit from it.

Shoulder pain

The most common causes of shoulder pain are adhesive capsulitis, rotator cuff tears and tendinopathy, and impingement.

As with knee pain, the same assessment routine largely applies.

First, pinpoint the location: Is the trouble spot the lateral shoulder and upper arm, the trapezial ridge, or the shoulder blade?

Next, assess pain on movement: Does the patient experience discomfort reaching overhead or behind the back, or moving at the glenohumeral joint/capsule and engaging the rotator cuff? Check for stiffness, weakness, and decreased range of motion in the rotator cuff.

Determine if the cause of the pain is traumatic or atraumatic and stems from an acute injury versus degeneration or overuse.

As with the knee, imaging is a major component of the assessment and typically involves the use of x-ray. An MRI may be required for evaluating full- and partial-thickness tears and when contemplating surgery.

MRI also is necessary for evaluating cases of acute, traumatic shoulder injury, and patients exhibiting disability suggestive of a rotator cuff tear in an otherwise healthy tendon.

Some pain can be treated with cortisone injections or regenerative therapies, which generally are given at the acromioclavicular or glenohumeral joints or in the subacromial space. A 2005 meta-analysis found that subacromial injections of corticosteroids are effective for improvement for rotator cuff tendinitis up to a 9‐month period.

Surgery may be warranted in some cases, Dr. Nakamoto said. These include adhesive capsulitis, rotator cuff tear, acute traumatic injury in an otherwise healthy tendon, and chronic (or acute-on-chronic) tears in a degenerative tendon following a trial of conservative therapy.

The Society for Cardiovascular Angiography and Interventions (SCAI) has issued the first statement on best practices for percutaneous axillary arterial access and training.

The position statement helps fill a gap amid increasing use of transaxillary access as an alternative to the femoral route for large-bore transcatheter aortic valve replacement (TAVR), endovascular aortic repair (EVAR), and mechanical circulatory support.

“The need for alternative access has increased as we are using more and more TAVR for our elderly population, and EVAR has also increased,” writing committee chair Arnold H. Seto, MD, Long Beach VA Health Care System (California) said in an interview. “There’s also a set of patients who require balloon pumps for a prolonged period, and people were using balloon pumps from the axillary approach, which were not custom-designed for that purpose.”

He noted that the evidence base leans heavily on case reports and case series, and that they were approached for guidance by a vendor developing a balloon pump specific to axillary access. “So that helped spur all of us to get together and decide to write up something on this topic, which was developing, but was certainly picking up steam rapidly.”

The statement was published in the Journal of the Society for Cardiovascular Angiography and Interventions, and it reflects the consensus of experts in heart failure, interventional cardiology and radiology, and cardiothoracic and vascular surgery. It reviews anatomic considerations and risks for percutaneous axillary access and suggests techniques for insertion, closure, and complication management.

Although the femoral artery is the most frequent access site for percutaneous large-bore procedures, the document notes that this approach may be limited in 13%-20% of patients because of prior surgeries or severe aortoiliac and/or iliofemoral atherosclerotic disease, tortuosity, or calcification.

“Absolutely, the femoral should be the predominant access site,” Dr. Seto said. Whenever there is a compromised femoral artery, “the axillary artery, which is rarely involved with atherosclerosis, makes for the most optimal alternative access. Other forms of alternative access, including transcaval and transcarotid, are possible but have their own issues and difficulties.”

Axillary access has traditionally been done through an open surgical approach, which allows for direct puncture, primary arterial repair, or placement of a sidearm conduit. Percutaneous transaxillary access avoids a surgical incision and general anesthesia and, theoretically, reduces the risk of infection, he said. It also allows for better mobility for patients, for example, who may have a balloon pump in place for weeks or even a month when waiting for a bridge to transplant.

In terms of technique, key recommendations include:

• Gaining access preferably through the left axillary
• Inserting the needle directly through the pectoralis minor into the second segment of the axillary artery
• Using a shallow-needle angle of 25-30 degrees to improve access success and decrease sheath malformation, kinking, bleeding, or vessel perforation
• Using micropuncture needles to minimize trauma to adjacent tissues
• Abducting the patient’s arm to 45-90 degrees to reduce tortuosity
• Using angiographic and ultrasound techniques to optimize vascular access

The latter point was the one area of debate among the writing committee, Dr. Seto observed. “That is one of the controversies: Should we make ultrasound mandatory? ... Everybody agreed that it can be quite useful and was likely to be useful because of its success in every other access area,” he said. “But in the absence of randomized evidence, we couldn’t make it mandatory or a strong recommendation. We just had to make it one of several options for the operator.”

The document highlights the need for familiarity with potential axillary artery complications and their management, noting that the axillary is more fragile than the femoral artery and, thus, potentially more prone to complications during instrumentation.

Data from the ARMS study in 102 patients undergoing transaxillary access for mechanical hemodynamic support reported 17 procedural complications, including 10 minor access site bleeding events, one stroke, and one pseudoaneurysm. A small study of 25 complex EVAR procedures reported a perioperative access complication rate of 8%, including one axillary artery dissection and one stenosis.

“Despite the brachial plexus being around there, there’s actually rare reports of neurologic injury and certainly none that have been permanent,” Dr. Seto said. “Also, stroke risk is probably more related to your device size and type of device rather than the approach itself.”

A significant amount of the paper is also devoted to training and privileging suggestions with an emphasis on a multidisciplinary team. The writing group recommends graduate medical education programs develop training curricula in percutaneous axillary artery access.

Those already in practice should participate in a formal training program that focuses on axillary artery anatomy, training in large bore access and closure devices, and didactic training in imaging modalities as applied to the axillary artery. Training can occur hands-on or using online simulations.

They also recommend outlining the potential need or role for proctoring and call for ongoing formal professional monitoring programs to evaluate operator outcomes using local or registry data.

“From a privileging standpoint, it was important for hospitals to be equally fair, regardless of the specialty that a requesting practitioner came from,” Dr. Seto said. “In other words, treat the vascular surgeons and interventional cardiologists and radiologists equally in terms of who has the privilege to do transaxillary access.”

The SCAI position statement has been endorsed by the American College of Cardiology, the Heart Failure Society of America, the Society of Interventional Radiology, and the Vascular & Endovascular Surgery Society.

Dr. Seto reported receiving honoraria from Getinge prior to initiation of the document. Disclosures for the rest of the writing group are available with the original article.

“Despite the brachial plexus being around there, there’s actually rare reports of neurologic injury and certainly none that have been permanent,” Dr. Seto said. “Also, stroke risk is probably more related to your device size and type of device rather than the approach itself.”

A significant amount of the paper is also devoted to training and privileging suggestions with an emphasis on a multidisciplinary team. The writing group recommends graduate medical education programs develop training curricula in percutaneous axillary artery access.

Those already in practice should participate in a formal training program that focuses on axillary artery anatomy, training in large bore access and closure devices, and didactic training in imaging modalities as applied to the axillary artery. Training can occur hands-on or using online simulations.

They also recommend outlining the potential need or role for proctoring and call for ongoing formal professional monitoring programs to evaluate operator outcomes using local or registry data.

“From a privileging standpoint, it was important for hospitals to be equally fair, regardless of the specialty that a requesting practitioner came from,” Dr. Seto said. “In other words, treat the vascular surgeons and interventional cardiologists and radiologists equally in terms of who has the privilege to do transaxillary access.”

The SCAI position statement has been endorsed by the American College of Cardiology, the Heart Failure Society of America, the Society of Interventional Radiology, and the Vascular & Endovascular Surgery Society.

Dr. Seto reported receiving honoraria from Getinge prior to initiation of the document. Disclosures for the rest of the writing group are available with the original article.

The Society for Cardiovascular Angiography and Interventions (SCAI) has issued the first statement on best practices for percutaneous axillary arterial access and training.

The position statement helps fill a gap amid increasing use of transaxillary access as an alternative to the femoral route for large-bore transcatheter aortic valve replacement (TAVR), endovascular aortic repair (EVAR), and mechanical circulatory support.

“The need for alternative access has increased as we are using more and more TAVR for our elderly population, and EVAR has also increased,” writing committee chair Arnold H. Seto, MD, Long Beach VA Health Care System (California) said in an interview. “There’s also a set of patients who require balloon pumps for a prolonged period, and people were using balloon pumps from the axillary approach, which were not custom-designed for that purpose.”

He noted that the evidence base leans heavily on case reports and case series, and that they were approached for guidance by a vendor developing a balloon pump specific to axillary access. “So that helped spur all of us to get together and decide to write up something on this topic, which was developing, but was certainly picking up steam rapidly.”

The statement was published in the Journal of the Society for Cardiovascular Angiography and Interventions, and it reflects the consensus of experts in heart failure, interventional cardiology and radiology, and cardiothoracic and vascular surgery. It reviews anatomic considerations and risks for percutaneous axillary access and suggests techniques for insertion, closure, and complication management.

Although the femoral artery is the most frequent access site for percutaneous large-bore procedures, the document notes that this approach may be limited in 13%-20% of patients because of prior surgeries or severe aortoiliac and/or iliofemoral atherosclerotic disease, tortuosity, or calcification.

“Absolutely, the femoral should be the predominant access site,” Dr. Seto said. Whenever there is a compromised femoral artery, “the axillary artery, which is rarely involved with atherosclerosis, makes for the most optimal alternative access. Other forms of alternative access, including transcaval and transcarotid, are possible but have their own issues and difficulties.”

Axillary access has traditionally been done through an open surgical approach, which allows for direct puncture, primary arterial repair, or placement of a sidearm conduit. Percutaneous transaxillary access avoids a surgical incision and general anesthesia and, theoretically, reduces the risk of infection, he said. It also allows for better mobility for patients, for example, who may have a balloon pump in place for weeks or even a month when waiting for a bridge to transplant.

In terms of technique, key recommendations include:

• Gaining access preferably through the left axillary
• Inserting the needle directly through the pectoralis minor into the second segment of the axillary artery
• Using a shallow-needle angle of 25-30 degrees to improve access success and decrease sheath malformation, kinking, bleeding, or vessel perforation
• Using micropuncture needles to minimize trauma to adjacent tissues
• Abducting the patient’s arm to 45-90 degrees to reduce tortuosity
• Using angiographic and ultrasound techniques to optimize vascular access

The latter point was the one area of debate among the writing committee, Dr. Seto observed. “That is one of the controversies: Should we make ultrasound mandatory? ... Everybody agreed that it can be quite useful and was likely to be useful because of its success in every other access area,” he said. “But in the absence of randomized evidence, we couldn’t make it mandatory or a strong recommendation. We just had to make it one of several options for the operator.”

The document highlights the need for familiarity with potential axillary artery complications and their management, noting that the axillary is more fragile than the femoral artery and, thus, potentially more prone to complications during instrumentation.

The U.S. Food and Drug Administration has approved mavacamten (Camzyos, Bristol Myers Squibb) to improve functional capacity and symptoms in adults with symptomatic New York Heart Association (NYHA) class II-III obstructive hypertrophic cardiomyopathy (oHCM).

Mavacamten is the first FDA-approved allosteric and reversible inhibitor selective for cardiac myosin that targets the underlying pathophysiology of the genetic disorder. It’s available in 2.5-mg, 5-mg, 10-mg, and 15-mg capsules.

“The approval of Camzyos represents a significant milestone for appropriate symptomatic obstructive HCM patients and their families, who have long awaited a new treatment option for this chronic and progressive disease,” Anjali T. Owens, MD, medical director of the Center for Inherited Cardiac Disease and assistant professor of medicine, University of Pennsylvania, Philadelphia, said in a news release.
 

‘Revolutionary’ change

The approval of mavacamten was based on data from the pivotal EXPLORER-HCM and EXPLORER-LTE (long-term extension) trial of adults with symptomatic NYHA class II-III oHCM.

In EXPLORER-HCM, treatment with mavacamten over 30 weeks led to significant improvement in exercise capacity, left ventricular outflow tract (LVOT) obstruction, NYHA functional class, and health status, as reported by this news organization.

The safety and efficacy findings seen at the end of the blinded, randomized, initial 30-week phase of EXPLORER-LTE were maintained in patients who continued treatment for a median of about 62 weeks.

Mavacamten represents “an almost revolutionary change” for the treatment of oHCM, Maya E. Guglin, MD, professor of clinical medicine and an advanced heart failure physician at Indiana University, Indianapolis, said during a press briefing earlier this month at the American College of Cardiology 2022 Scientific Session earlier this month.

“Until now, there was no good medical treatment for symptomatic oHCM. This will change the landscape, and without question it will change guidelines for treating oHCM,” Dr. Guglin said.

The product information for mavacamten includes a boxed warning citing a risk for heart failure.

Echocardiogram assessments of left ventricular ejection fraction (LVEF) are required before and during treatment.

Starting mavacamten in patients with LVEF below 55% is not recommended and the drug should be interrupted if LVEF falls below 50% at any visit or if the patient experiences heart failure symptoms or worsening clinical status.

Concomitant use of mavacamten with certain cytochrome P450 inhibitors or discontinuation of certain cytochrome P450 inducers can increase the risk for heart failure attributable to systolic dysfunction. Therefore, its use is contraindicated in patients using moderate to strong CYP2C19 inhibitors or strong CYP3A4 inhibitors, and moderate to strong CYP2C19 inducers or moderate to strong CYP3A4 inducers.

Because of the risk for heart failure attributable to systolic dysfunction, mavacamten is only available through the Camzyos Risk Evaluation and Mitigation Strategy (REMS) Program.

Patients implanted with the Medtronic HeartWare ventricular assist device (HVAD) System who develop pump thrombosis could have a welding defect in the internal pump causing the pump to malfunction, the Food and Drug Administration said in a letter to health care professionals. 

Medtronic has sent providers an urgent medical device notice about the pump weld defect and is trying to identify which HVAD pumps are affected.

The Medtronic HVAD System was approved as a bridge to heart transplantation in 2012. Since then, it has been fraught with problems.

This past June, the company announced it was stopping all sales of the device and advised physicians to stop implanting it, as reported by this news organization. 
 

Pump thrombosis

Medtronic has received complaints of suspected pump thrombosis in three patients with the HVAD System.

All three patients presented with one or more of the following signs or symptoms: grinding sound, transient power spikes on log files and high watt alarms, elevated lactate dehydrogenase, and low motor speed resulting in low perfusion or dizziness or lightheadedness.

Inspection of the returned pumps in these three cases identified a malfunction of the internal pump. The pumps were exchanged in all three patients. Two patients died after the pump exchange.

The FDA does not recommend the elective removal of properly functioning systems.

“Decisions about removing or exchanging the Medtronic HVAD System should be made by health care providers and patients on a case-by-case basis, considering the patient’s clinical status and surgical risks,” the agency advised.

Patients who present with one or more of the signs or symptoms of pump thrombosis should be first treated for pump thrombosis.

If symptoms fail to resolve, providers may consider whether the patient is a candidate for pump exchange, heart transplant, or pump explant for recovery, taking into account the patient’s clinical condition and surgical risks.

For patients with any of the signs and symptoms of pump thrombosis, logfiles from the controller should be uploaded to Medtronic.

The FDA is working with Medtronic to monitor for any adverse events related to pump weld defects and ensure patients with the HVAD implant continue to receive appropriate follow-up monitoring.

Problems related to the Medtronic HVAD System should be reported to the FDA’s MedWatch program.

No wonder we feel worse after naps

Some of us have hectic schedules that may make a nap feel more necessary. It’s common knowledge that naps shouldn’t be too long – maybe 20 minutes or so – but if you frequently take 3-hour naps and wake up thinking you’re late for school even though you’re 47 and have your PhD, this LOTME is for you.

Judith Shidlowsky/Pixabay

Studies have shown that there is a link between napping during the day and Alzheimer’s/cognitive decline, but now we’ve got a double whammy for you: Longer and more frequent napping is linked to worse cognition after a year, and in turn, those with cognitive decline and Alzheimer’s are known to nap longer and more frequently during the day.

“We now know that the pathology related to cognitive decline can cause other changes in function,” he said. “It’s really a multisystem disorder, also including difficulty sleeping, changes in movement, changes in body composition, depression symptoms, behavioral changes, etc.,” coauthor Aron Buchman, MD, said in a statement from Rush University Medical Center.

The investigators monitored 1,400 patients over the course of 14 years with wrist bracelets that recorded when a person was not active during the day and considered that a nap.

At the beginning of the study, 75% of the study subjects had no cognitive impairment, 19.5% had some cognitive impairment, and approximately 4% had Alzheimer’s. Napping during the day only increased about 11 minutes a year for those with no signs of cognitive impairment, but those who showed significantly more signs of cognitive decline doubled their nap time and those actually diagnosed with Alzheimer’s tripled theirs.

The investigators did not imply that napping causes Alzheimer’s, but they noted that people who are older and nap more than an hour a day are 40% more likely to be at risk. It is something to consider and monitor.

Sometimes, after all, a nap seems like the best idea ever, but more often than not we wake up feeling 10 times worse. Our bodies may be giving us a heads up.

Pokemon Go away depression

The summer of 2016 was a great time if you happened to be a fan of Pokemon. Which is quite a lot of people. For almost 20 years millions have enjoyed the games and animated series, but Pokemon Go brought the thrill of catching Pokemon to life in a whole new way. For the first time, you could go out into the world and pretend you were a real Pokemon trainer, and everywhere you went, there would be others like you.

Gerd Altmann/Pixabay

The ability to chase after Pikachu and Charizard in real life (well, augmented reality, but close enough) seemed to bring people a lot of joy, but seemed is never good enough for science. Can’t have anecdotes, we need data! So researchers at the London School of Economics and Political Science conducted a study into how Pokemon Go affected local Internet search rates of depression as the game was released slowly around the world.

Through analyzing Google Trend data of words like “depression,” “anxiety,” and “stress,” the researchers found that the release of Pokemon Go was significantly associated with a noticeable, though short-term, drop in depression-related Internet searches. Location-based augmented reality games may alleviate symptoms of mild depression, the researchers said, as they encourage physical activity, face-to-face socialization, and exposure to nature, though they added that simply going outside is likely not enough to combat clinical cases of severe depression.

Still, augmented reality games represent a viable target for public health investment, since they’re easy to use and inexpensive to make. That said, we’re not sure we want the FDA or CDC making a new Pokemon Go game. They’d probably end up filling the streets with Mr. Mime. And no one would leave their house for that.
 

And now a word from our sponsor

How many times has this happened to you? You need to repair a jet engine, inspect a nuclear reactor cooling system, AND perform bowel surgery, but you can’t carry around all the heavy, old-fashioned tools needed for those jobs.

Well, we’ve got one tool that can do it all! And that tool is a snake. No, it’s a robot.

Nottingham University

It’s both! It’s the COntinuum roBot for Remote Applications. COBRA is the robot that looks like a snake! A snake that’s 5 meters long but only as thick as a pencil (about 9 mm in diameter). A robot with “extraordinary manoeuvrability and responsiveness due to … a compliant-joint structure and multiple continuous sections that enable it to bend at around 90 degrees,” according to the team at the University of Nottingham (England) that developed it.

COBRA comes equipped with a stereovision camera and a miniature cutting tool to perform complex industrial repair, but other devices can be interchanged for possible medical use.

COBRA and its joystick-like controller were designed to be easy to use. Dr. Oladejo Olaleye, the ear, nose, and throat and robotic surgeon at University Hospitals of Leicester who is directing its surgical development, was able to use COBRA on a dummy after just 5 minutes of training. He called it “the future of diagnostic endoscopy and therapeutic surgery.”

Don’t be the last aircraft engineer/nuclear technician/surgeon on your block to have this ultraslender, ultramaneuverable reptilian repair robot. Get your COBRA now! Operators are standing by.

Disclaimer: Robot is still under development and not yet on sale.

Rule, (worm) Britannia!

As long as there have been people, there have been parasitic worms living in their guts. Helminth infection is a continuing and largely ignored crisis in poor, tropical nations, though worm-based diseases have been basically eliminated from wealthier countries.

English Heritage

This wasn’t always the case, however, as a study published in PLOS Neglected Tropical Diseases (now there’s a specific topic) has found. The researchers detail the glorious history of helminth infestation in the United Kingdom from the Victorian era all the way back to prehistory, scouring hundreds of skeletons found in 17 sites across the country for eggs, which can remain intact for thousands of years.

The researchers found that two eras in particular had very high rates of infection. Unsurprisingly, the late medieval era was one of them, but the other is less obvious. The Romans were famous for their hygiene, their baths, and their plumbing, but maybe they also should be famous for the abundance of worms in their bellies. That doesn’t make sense at first: Shouldn’t good hygiene lower infection? The benefits of a good sewer system, however, are lessened when the waste containing said infectious organisms is used to fertilize crops. Recycling is generally a good thing, but less so when you’re recycling parasitic worms.

Curiously, of the three sites from the industrial age, only the one in London had high levels of worm infestation. Considering how dirty and cramped 19th-century British cities were, one might expect disease to run rampant (tuberculosis certainly did), but the sites in Oxford and Birmingham were almost devoid of worms. The researchers theorized that this was because of access to clean well water. Or maybe worms just have a thing for London. [Editor’s note: It’s probably not that.]

COBRA and its joystick-like controller were designed to be easy to use. Dr. Oladejo Olaleye, the ear, nose, and throat and robotic surgeon at University Hospitals of Leicester who is directing its surgical development, was able to use COBRA on a dummy after just 5 minutes of training. He called it “the future of diagnostic endoscopy and therapeutic surgery.”

Don’t be the last aircraft engineer/nuclear technician/surgeon on your block to have this ultraslender, ultramaneuverable reptilian repair robot. Get your COBRA now! Operators are standing by.

Rule, (worm) Britannia!

As long as there have been people, there have been parasitic worms living in their guts. Helminth infection is a continuing and largely ignored crisis in poor, tropical nations, though worm-based diseases have been basically eliminated from wealthier countries.

English Heritage

This wasn’t always the case, however, as a study published in PLOS Neglected Tropical Diseases (now there’s a specific topic) has found. The researchers detail the glorious history of helminth infestation in the United Kingdom from the Victorian era all the way back to prehistory, scouring hundreds of skeletons found in 17 sites across the country for eggs, which can remain intact for thousands of years.

The researchers found that two eras in particular had very high rates of infection. Unsurprisingly, the late medieval era was one of them, but the other is less obvious. The Romans were famous for their hygiene, their baths, and their plumbing, but maybe they also should be famous for the abundance of worms in their bellies. That doesn’t make sense at first: Shouldn’t good hygiene lower infection? The benefits of a good sewer system, however, are lessened when the waste containing said infectious organisms is used to fertilize crops. Recycling is generally a good thing, but less so when you’re recycling parasitic worms.

Curiously, of the three sites from the industrial age, only the one in London had high levels of worm infestation. Considering how dirty and cramped 19th-century British cities were, one might expect disease to run rampant (tuberculosis certainly did), but the sites in Oxford and Birmingham were almost devoid of worms. The researchers theorized that this was because of access to clean well water. Or maybe worms just have a thing for London. [Editor’s note: It’s probably not that.]

No wonder we feel worse after naps

Some of us have hectic schedules that may make a nap feel more necessary. It’s common knowledge that naps shouldn’t be too long – maybe 20 minutes or so – but if you frequently take 3-hour naps and wake up thinking you’re late for school even though you’re 47 and have your PhD, this LOTME is for you.

Studies have shown that there is a link between napping during the day and Alzheimer’s/cognitive decline, but now we’ve got a double whammy for you: Longer and more frequent napping is linked to worse cognition after a year, and in turn, those with cognitive decline and Alzheimer’s are known to nap longer and more frequently during the day.

“We now know that the pathology related to cognitive decline can cause other changes in function,” he said. “It’s really a multisystem disorder, also including difficulty sleeping, changes in movement, changes in body composition, depression symptoms, behavioral changes, etc.,” coauthor Aron Buchman, MD, said in a statement from Rush University Medical Center.

The investigators monitored 1,400 patients over the course of 14 years with wrist bracelets that recorded when a person was not active during the day and considered that a nap.

At the beginning of the study, 75% of the study subjects had no cognitive impairment, 19.5% had some cognitive impairment, and approximately 4% had Alzheimer’s. Napping during the day only increased about 11 minutes a year for those with no signs of cognitive impairment, but those who showed significantly more signs of cognitive decline doubled their nap time and those actually diagnosed with Alzheimer’s tripled theirs.

The investigators did not imply that napping causes Alzheimer’s, but they noted that people who are older and nap more than an hour a day are 40% more likely to be at risk. It is something to consider and monitor.

Sometimes, after all, a nap seems like the best idea ever, but more often than not we wake up feeling 10 times worse. Our bodies may be giving us a heads up.

Pokemon Go away depression

The summer of 2016 was a great time if you happened to be a fan of Pokemon. Which is quite a lot of people. For almost 20 years millions have enjoyed the games and animated series, but Pokemon Go brought the thrill of catching Pokemon to life in a whole new way. For the first time, you could go out into the world and pretend you were a real Pokemon trainer, and everywhere you went, there would be others like you.

The ability to chase after Pikachu and Charizard in real life (well, augmented reality, but close enough) seemed to bring people a lot of joy, but seemed is never good enough for science. Can’t have anecdotes, we need data! So researchers at the London School of Economics and Political Science conducted a study into how Pokemon Go affected local Internet search rates of depression as the game was released slowly around the world.

Through analyzing Google Trend data of words like “depression,” “anxiety,” and “stress,” the researchers found that the release of Pokemon Go was significantly associated with a noticeable, though short-term, drop in depression-related Internet searches. Location-based augmented reality games may alleviate symptoms of mild depression, the researchers said, as they encourage physical activity, face-to-face socialization, and exposure to nature, though they added that simply going outside is likely not enough to combat clinical cases of severe depression.

Still, augmented reality games represent a viable target for public health investment, since they’re easy to use and inexpensive to make. That said, we’re not sure we want the FDA or CDC making a new Pokemon Go game. They’d probably end up filling the streets with Mr. Mime. And no one would leave their house for that.
 

And now a word from our sponsor

How many times has this happened to you? You need to repair a jet engine, inspect a nuclear reactor cooling system, AND perform bowel surgery, but you can’t carry around all the heavy, old-fashioned tools needed for those jobs.

Well, we’ve got one tool that can do it all! And that tool is a snake. No, it’s a robot.

Nottingham University

It’s both! It’s the COntinuum roBot for Remote Applications. COBRA is the robot that looks like a snake! A snake that’s 5 meters long but only as thick as a pencil (about 9 mm in diameter). A robot with “extraordinary manoeuvrability and responsiveness due to … a compliant-joint structure and multiple continuous sections that enable it to bend at around 90 degrees,” according to the team at the University of Nottingham (England) that developed it.

COBRA comes equipped with a stereovision camera and a miniature cutting tool to perform complex industrial repair, but other devices can be interchanged for possible medical use.

BOSTON – According to the best available data, solid organ transplant recipients (SOTRs) at highest risk for developing skin cancer are thoracic organ recipients, those aged 50 or older at the time of the transplant, and males.

White patients who meet these criteria should be screening within 2 years after transplant, while Black patients should be screened within 5 years after transplant, Ally-Khan Somani, MD, PhD, said at the annual meeting of the American Academy of Dermatology.

Dr. Somani, director of dermatologic surgery and the division of cutaneous oncology at Indiana University, Indianapolis, based his remarks on consensus screening guidelines assembled from three rounds of Delphi method surveys with 47 dermatologists and 37 transplant physicians, with the goal of establishing skin cancer screening recommendations for SOTRs. Among the dermatologists surveyed, 45% were Mohs surgeons and 55% were general dermatologists.

The panel recommended that the transplant team should perform risk assessment for SOTRs to risk stratify patients for skin cancer screening (high risk vs. low risk). They also proposed that dermatologists perform skin cancer screening by full-body skin examinations, and that SOTRs with a history of skin cancer should continue with routine skin cancer surveillance as recommended by their dermatologists.

Those at low risk for skin cancer include abdominal organ recipients, SOTR age of younger than 50 at time of transplant, and female gender. The guidelines recommend that White, Asian, and Hispanic patients who meet those criteria should be screened within 5 years after transplant, while no consensus was reached for Black patients who meet those criteria.

Based on posttransplant skin cancer incidence rates, risk is increased among males, Whites, thoracic organ recipients, and being age 50 or older, Dr. Somani said. “At our institution, we make sure there’s a good connection between our transplant teams and dermatologists. We recommend rapid referral for suspicious lesions and we educate patients and screen them within 1 year of transplant, or sooner for high-risk patients. Surveillance is increased to every 3 or 4 months for patients with a history of multiple or high-risk cancers or sooner, followed by routine surveillance as recommended by the patient’s dermatologist.”

To risk stratify patients on the development of their first skin cancer post transplantation, researchers developed the Skin and Ultraviolet Neoplasia Transplant Risk Assessment Calculator (SUNTRAC), a prediction tool with a freely available app. Data for the tool were drawn from the Transplant Skin Cancer Network study, a 5-year analysis of 6,340 adult recipients of a first solid organ transplant at 26 transplant centers in the United States. It generates a risk score for SOTRs (low, medium, high, or very high), which informs transplant care providers of a patient’s risk of skin cancer.

Dr. Somani disclosed that he has received grants and funding from Castle Biosciences. He is an adviser to Cook Biotech and a consultant to Sanara MedTech.
