The Society for Cardiovascular Angiography and Interventions has issued an updated expert consensus statement to provide clearer guidance on what percutaneous coronary angioplasty cases can be done in outpatient settings such as ambulatory surgery centers (ASCs) and office-based laboratories and which are best left to more traditional settings, such as hospitals with full cardiac support.

PCI has evolved quickly since SCAI issued its last update almost 9 years ago. The updated statement, published online in the Journal of the Society for Cardiovascular Angiography and Interventions, notes that the proportion of same-day PCI discharges has increased from 4.5% in 2009 to 28.6% in 2017.

The statement also notes that the Medicare facility fee for outpatient PCI in an ASC is about 40% less than the hospital fee: $6,111 versus $10,258 for the facility fee for 2022. The Centers for Medicare & Medicaid Services in 2020 extended coverage for PCIs in ASCs.
 

Rationale for update

Writing group chair Cindy Grines, MD, explained the rationale for updating the statement now. “The 2014 SCAI statement was very conservative, recommending only the simplest of cases be done without surgical backup,” Dr. Grines, chief scientific officer at Northside Hospital Cardiovascular Institute in Atlanta, said in an interview.

The statement drew on 12 global studies from 2015 to 2022 that evaluated more than 8 million PCIs at facilities with and without surgery on site. Dr. Grines noted those studies reported complication rates as low as 0.1% in PCI procedures in centers without surgical backup.

She also noted that the writing committee also received input that “by restricting the use of certain devices such as atherectomy, some patients who needed it as a bailout could be harmed.”

Another factor in prompting the statement update, Dr. Grines said: “Many hospitals have consolidated into heath systems, and these systems consolidated bypass surgery into one center. Therefore, centers with high volume, experienced operators, and excellent outcomes were now left with no surgery on site. It didn’t make sense to withdraw complex PCI from these centers who haven’t sent a patient for emergency bypass in several years.”
 

Statement guidance

The centerpiece of the update is an algorithm that covers the range of settings for PCI, from having a surgeon on site to ACS or office-based lab.

For example, indications for on-site surgical capability are PCI of the last remaining patent vessel or retrograde approach to epicardial chronic total occlusion (CTO), and when the patient is a candidate for surgery.

Indications for PCI in a hospital without on-site surgery but with percutaneous ventricular assist device or extracorporeal membrane oxygenation, calcium modification devices and high PCI volume are patients with decreased left ventricular ejection fraction, unprotected left main artery, CTO, or degenerated vein grafts.

For patients at high risk for transfusion, acute kidney injury or vascular complications, or who have high baseline respiratory risk, a hospital without on-site surgery but with respiratory care, blood bank, and vascular surgery services is indicated.

And for patients with none of the aforementioned characteristics or risks, ASC, office-based lab, or any hospital facility is acceptable.

The statement also provides guidance for operator experience. Those with less than 3 years’ experience, considered to have limited exposure to atherectomy devices and limited ST-segmented elevation MI (STEMI)/shock experience, should avoid doing PCIs in an ASC and performing atherectomy cases on their own, and have a colleague review case selection and assist in higher-risk cases. Experienced (3-10 years’ experience) and very experienced (more than 10 years’) should be able to perform in any setting and be competent with, if not highly experienced with, atherectomy and STEMI/shock.

Dr. Grines acknowledged the writing group didn’t want to set a specific operator volume requirement. “However, we recognize that lifetime operator experience is particularly important in more complex cases such as CTO, atherectomy, bifurcation stenoses, etc.,” she said. “In addition, performing these cases at a larger institution that has other operators that may assist in the event of a complication is very important. Specifically, we did not believe that recent fellow graduates with less than 3 years in practice or low-volume operators should attempt higher-risk cases in a no-SOS [surgeon-on-site] setting or perform cases in ASC or office-based labs where no colleagues are there to assist in case of a complication.”

In an interview, Gregory J. Dehmer, MD, professor of medicine at Virginia Tech University, Roanoke, reprised the theme of his accompanying editorial. “Things are evolving again, as Bob Dylan would say, ‘The Times They Are A-Changin’, so it’s very timely that the society in collaboration with other professional societies updated what are guidelines and rules of road if you’re going to do PCI in ASCs or office based laboratories,” said Dr. Dehmer, who chaired the writing committees of the 2007 and 2014 SCAI expert statements on PCI.

Having this statement is important for centers that don’t have on-site surgical backup, he said. “You couldn’t sustain a PCI operation at a rural hospital on just acute MIs alone. The key thing is that all of this built upon numerous studies both in the U.S. and abroad that showed the safety of doing elective cases – not only STEMIs, but elective PCI – at facilities without on-site surgery.”

CMS pushed the envelope when it decided to reimburse PCIs done in ASCs, Dr. Dehmer said. “That was not based on a lot of data. It was kind of a leap of faith. It’s logical that this should work, but in order for it to work and be safe for pats you have to follow the rules. That’s where SCAI stepped in at this point and said this is a whole new environment and we need to set some ground rules for physicians of who and who should not be having these procures in an office-based lab or an ambulatory surgery center.”

Dr. Grines and Dr. Dehmer have no relevant disclosures.

Emergencies happen anywhere, anytime, and sometimes physicians find themselves in situations where they are the only ones who can help. Is There a Doctor in the House? is a Medscape series telling these stories.

I was coming off a 48-hour shift plus a day of doing outpatient sedation at Sparrow Hospital in Lansing. It was December and Michigan-cold. The roads were fine – no snow – but I noticed an unusual amount of traffic on the freeway. Then I saw smoke coming from an overpass up ahead.

I drove on the side of the road where I wasn’t really supposed to and got closer. An SUV had crashed into one of the big concrete structures under the bridge. I saw people running around but wasn’t able to spot EMS or any health care workers. From where I was, I could identify four kids who had already been extricated and one adult still in the driver’s seat. I estimated the kids’ ages were around 7, 5, 3, and an infant who was a few months old. I left my car and went to help.

I was able to peg the ages correctly because I’m a pediatric critical care physician. As a specialty, we’re not commonly known. We oversee patient care in intensive care units, except the patients are children. Part of the job is that we’re experts at triaging. We recognize what’s life-threatening and less so.

The kids were with some adults who kept them warm with blankets. I examined each of them. The infant was asleep but arousable and acting like a normal baby. The 3-year-old boy was vomiting and appeared very fatigued. The 5-year-old boy had a forehead laceration and was in and out of consciousness. The 7-year-old girl was screaming because of different injuries.

While all of the children were concerning to me, I identified one in particular: the 5-year-old boy. It was obvious he needed serious medical attention and fast. So, I kept that little guy in mind. The others had sustained significant injuries, but my best guess was they could get to a hospital and be stabilized.

That said, I’m a trauma instructor, and one of the things I always tell trainees is: Trauma is a black box. On the outside, it may seem like a patient doesn’t have a lot of injuries. But underneath, there might be something worse, like a brain injury. Or the chest might have taken a blunt impact affecting the heart. There may be internal bleeding somewhere in the belly. It’s really hard to tease out what exactly is going on without equipment and testing.

I didn’t even have a pulse oximeter or heart rate monitor. I pretty much just went by the appearance of the child: pulse, heart rate, awareness, things like that.

After the kids, I moved to look at the man in the car. The front end had already caught fire. I could see the driver – the kids’ father, I guessed – unconscious and hunched over. I was wondering, Why hasn’t this guy been extricated?

I approached the car on the front passenger side. And then I just had this feeling. I knew I needed to step back. Immediately.

I did. And a few seconds later, the whole car exploded in flames.

I believe God is in control of everything. I tried to get to that man. But the scene was unsafe. Later I learned that several people, including a young nurse at the scene, had tried to get to him as well.

When EMS came, I identified myself. Obviously, these people do very, very important work. But they may be more used to the 60-year-old heart attack, the 25-year-old gunshot wound, the occasional ill child. I thought that four kids – each with possible critical poly-traumatic injuries – posed a challenge to anyone.

I told them, “This is what I do on a daily basis, and this is the kid I’m worried about the most. The other kids are definitely worrisome, but I would prioritize getting this kid to the hospital first. Can I ride with you?” They agreed.

We got that boy and his older sister into the first ambulance (she was in a lot of pain, the result of a femur fracture). The two other kids rode in the second ambulance. The hospital where I had just left was 10 minutes away. I called the other pediatric critical care doctor there, my partner. He thought I was calling for a routine issue – no such luck. I said, “I’m with four kids who are level-1 traumas in two ambulances and I’m heading to the hospital right now, ETA 10 minutes.”

En route, I thought the little boy might lose consciousness at any moment. He needed a breathing tube, and I debated whether it should be done in the ambulance vs. waiting until we got to the emergency room. Based on my judgment and his vital signs, I elected to wait to have it done it in a more controlled environment. Had I felt like he was in immediate need of an airway, I would’ve attempted it. But those are the tough calls that you must make.

My partner had alerted the trauma and emergency medicine teams at the hospital. By the time we arrived, my partner was down in the ER with the trauma team and ER staff. Everyone was ready. Then it was like divide and conquer. He attended to one of the kids. The ER team and I were with the little guy I was really worried about. We had his breathing tube in within minutes. The trauma team attended to the other two.

All the kids were stabilized and then admitted to the pediatric intensive care unit. I’m happy to say that all of them did well in the end. Even the little guy I was worried about the most.

I must say this incident gave me perspective on what EMS goes through. The field medicine we do in the United States is still in its infancy in a lot of ways. One of the things I would love to see in the future is a mobile ICU. After a critical illness hits, sometimes you only have seconds, minutes, maybe hours if you’re lucky. The earlier you can get patients the treatment they need, the better the outcomes.

I like taking care of critically ill children and their families. It fits my personality. And it’s a wonderful cause. But you have to be ready for tragic cases like this one. Yes, the children came out alive, but the accident claimed a life in a horrible way. And there was nothing I could do about it.

Critical care takes an emotional, psychological, and physical toll. It’s a roller coaster: Some kids do well; some kids don’t do well. All I can do is hold myself accountable. I keep my emotions in check, whether the outcome is positive or negative. And I do my best.

I told them, “This is what I do on a daily basis, and this is the kid I’m worried about the most. The other kids are definitely worrisome, but I would prioritize getting this kid to the hospital first. Can I ride with you?” They agreed.

We got that boy and his older sister into the first ambulance (she was in a lot of pain, the result of a femur fracture). The two other kids rode in the second ambulance. The hospital where I had just left was 10 minutes away. I called the other pediatric critical care doctor there, my partner. He thought I was calling for a routine issue – no such luck. I said, “I’m with four kids who are level-1 traumas in two ambulances and I’m heading to the hospital right now, ETA 10 minutes.”

En route, I thought the little boy might lose consciousness at any moment. He needed a breathing tube, and I debated whether it should be done in the ambulance vs. waiting until we got to the emergency room. Based on my judgment and his vital signs, I elected to wait to have it done it in a more controlled environment. Had I felt like he was in immediate need of an airway, I would’ve attempted it. But those are the tough calls that you must make.

My partner had alerted the trauma and emergency medicine teams at the hospital. By the time we arrived, my partner was down in the ER with the trauma team and ER staff. Everyone was ready. Then it was like divide and conquer. He attended to one of the kids. The ER team and I were with the little guy I was really worried about. We had his breathing tube in within minutes. The trauma team attended to the other two.

All the kids were stabilized and then admitted to the pediatric intensive care unit. I’m happy to say that all of them did well in the end. Even the little guy I was worried about the most.

I must say this incident gave me perspective on what EMS goes through. The field medicine we do in the United States is still in its infancy in a lot of ways. One of the things I would love to see in the future is a mobile ICU. After a critical illness hits, sometimes you only have seconds, minutes, maybe hours if you’re lucky. The earlier you can get patients the treatment they need, the better the outcomes.

I like taking care of critically ill children and their families. It fits my personality. And it’s a wonderful cause. But you have to be ready for tragic cases like this one. Yes, the children came out alive, but the accident claimed a life in a horrible way. And there was nothing I could do about it.

Critical care takes an emotional, psychological, and physical toll. It’s a roller coaster: Some kids do well; some kids don’t do well. All I can do is hold myself accountable. I keep my emotions in check, whether the outcome is positive or negative. And I do my best.

Beyond Reps (dba IronRod Health and Cardiac Monitoring Services) has agreed to pay $673,200 to resolve allegations that it submitted false claims to federal health care programs relating to remote cardiac monitoring services.

The U.S. Department of Justice alleges that between Jan. 1, 2018, and April 30, 2021, IronRod, with headquarters in Phoenix, used technicians who lacked required credentials to conduct remote cardiac monitoring readings.

The government further alleges that between June 1, 2018, and Aug. 20, 2018, the company misrepresented that it performed services in New York state in order to get higher reimbursements from Medicare for remote cardiac monitoring services.

“Providers that seek payment from federal health programs are required to follow laws meant to protect beneficiaries, as well as to protect the integrity of those programs,” U.S. Attorney Trini E. Ross said in a statement.

“Our office is committed to pursuing cases against any provider that cuts corners or seeks to obtain payments for which they are not entitled,” Ms. Ross said.

A request to Beyond Reps for comment was not returned.

The civil settlement resolves claims brought under the qui tam (whistleblower) provisions of the False Claims Act by Coleen DeGroat.

Under those provisions, a private party can file an action on behalf of the United States and receive a portion of any recovery. Ms. DeGroat will receive a share of the settlement.

When I was a child, I watched syndicated episodes of the original “Star Trek.” I was dazzled by the space travel, sure, but also the medical technology.

A handheld “tricorder” detected diseases, while an intramuscular injector (“hypospray”) could treat them. Sickbay “biobeds” came with real-time health monitors that looked futuristic at the time but seem primitive today.

Such visions inspired a lot of us kids to pursue science. Little did we know the real-life advances many of us would see in our lifetimes.

Artificial intelligence helping to spot disease, robots performing surgery, even video calls between doctor and patient – all these once sounded fantastical but now happen in clinical care.

Now, in the 23rd year of the 21st century, you might not believe wht we’ll be capable of next. Three especially wild examples are moving closer to clinical reality. 
 

Human hibernation

Captain America, Han Solo, and “Star Trek” villain Khan – all were preserved at low temperatures and then revived, waking up alive and well months, decades, or centuries later. These are fictional examples, to be sure, but the science they’re rooted in is real.

Rare cases of accidental hypothermia prove that full recovery is possible even after the heart stops beating. The drop in body temperature slows metabolism and reduces the need for oxygen, stalling brain damage for an hour or more. (In one extreme case, a climber survived after almost 9 hours of efforts to revive him.)

Useful for a space traveler? Maybe not. But it’s potentially huge for someone with life-threatening injuries from a car accident or a gunshot wound.

That’s the thinking behind a breakthrough procedure that came after decades of research on pigs and dogs, now in a clinical trial. The idea: A person with massive blood loss whose heart has stopped is injected with an ice-cold fluid, cooling them from the inside, down to about 50° F.

Doctors already induce more modest hypothermia to protect the brain and other organs after cardiac arrest and during surgery on the aortic arch (the main artery carrying blood from the heart).

But this experimental procedure – called emergency preservation and resuscitation (EPR) – goes far beyond that, dramatically “decreasing the body’s need for oxygen and blood flow,” says Samuel Tisherman, MD, a trauma surgeon at the University of Maryland Medical Center and the trial’s lead researcher. This puts the patient in a state of suspended animation that “could buy time for surgeons to stop the bleeding and save more of these patients.”

The technique has been done on at least six patients, though none were reported to survive. The trial is expected to include 20 people by the time it wraps up in December, according to the listing on the U.S. clinical trials database. Though given the strict requirements for candidates (emergency trauma victims who are not likely to survive), one can’t exactly rely on a set schedule.

Still, the technology is promising. Someday we may even use it to keep patients in suspended animation for months or years, experts predict, helping astronauts through decades-long spaceflights, or stalling death in sick patients awaiting a cure.
 

Artificial womb

Another sci-fi classic: growing human babies outside the womb. Think the fetus fields from “The Matrix,” or the frozen embryos in “Alien: Covenant.”

In 1923, British biologist J.B.S. Haldane coined a term for that – ectogenesis. He predicted that 70% of pregnancies would take place, from fertilization to birth, in artificial wombs by 2074. That many seems unlikely, but the timeline is on track.

Developing an embryo outside the womb is already routine in in vitro fertilization. And technology enables preterm babies to survive through much of the second half of gestation. Normal human pregnancy is 40 weeks, and the youngest preterm baby ever to survive was 21 weeks and 1 day old, just a few days younger than a smattering of others who lived.

The biggest obstacle for babies younger than that is lung viability. Mechanical ventilation can damage the lungs and lead to a chronic (sometimes fatal) lung disease known as bronchopulmonary dysplasia. Avoiding this would mean figuring out a way to maintain fetal circulation – the intricate system that delivers oxygenated blood from the placenta to the fetus via the umbilical cord. Researchers at Children’s Hospital of Philadelphia have done this using a fetal lamb.

The key to their invention is a substitute placenta: an oxygenator connected to the lamb’s umbilical cord. Tubes inserted through the umbilical vein and arteries carry oxygenated blood from the “placenta” to the fetus, and deoxygenated blood back out. The lamb resides in an artificial, fluid-filled amniotic sac until its lungs and other organs are developed.

Fertility treatment could benefit, too. “An artificial womb may substitute in situations in which a gestational carrier – surrogate – is indicated,” says Paula Amato, MD, a professor of obstetrics and gynecology at Oregon Health and Science University, Portland. (Dr. Amato is not involved in the CHOP research.) For example: when the mother is missing a uterus or can’t carry a pregnancy safely.

No date is set for clinical trials yet. But according to the research, the main difference between human and lamb may come down to size. A lamb’s umbilical vessels are larger, so feeding in a tube is easier. With today’s advances in miniaturizing surgical methods, that seems like a challenge scientists can overcome.
 

Messenger RNA therapeutics

Back to “Star Trek.” The hypospray injector’s contents could cure just about any disease, even one newly discovered on a strange planet. That’s not unlike messenger RNA (mRNA) technology, a breakthrough that enabled scientists to quickly develop some of the first COVID-19 vaccines.

But vaccines are just the beginning of what this technology can do.

A whole field of immunotherapy is emerging that uses mRNA to deliver instructions to produce chimeric antigen receptor–modified immune cells (CAR-modified immune cells). These cells are engineered to target diseased cells and tissues, like cancer cells and harmful fibroblasts (scar tissue) that promote fibrosis in, for example, the heart and lungs.

The field is bursting with rodent research, and clinical trials have started for treating some advanced-stage malignancies.

Actual clinical use may be years away, but if all goes well, these medicines could help treat or even cure the core medical problems facing humanity. We’re talking cancer, heart disease, neurodegenerative disease – transforming one therapy into another by simply changing the mRNA’s “nucleotide sequence,” the blueprint containing instructions telling it what to do, and what disease to attack.

As this technology matures, we may start to feel as if we’re really on “Star Trek,” where Dr. Leonard “Bones” McCoy pulls out the same device to treat just about every disease or injury.

The reproductive hormone kisspeptin may be a treatment option for low sexual desire in men and women, according to results from two small randomized controlled trials.

The data suggest that injections of kisspeptin can boost sexual desire in men and women and can increase penile rigidity in men.

Together, these two studies provide proof of concept for the development of kisspeptin-based therapeutics for men and women with distressing hypoactive sexual desire disorder (HSDD), study investigator Alexander Comninos, MD, PhD, Imperial College London, said in a news release.

One study was published online Feb. 3, 2022, in JAMA Network Open. The other was published in October 2022.
 

Unmet need

HSDD affects up to 10% of women and 8% of men worldwide and leads to psychological and social harm, the news release noted.

“There is a real unmet need to find new, safer, and more effective therapies for this distressing condition for both women and men seeking treatment,” Dr. Comninos said.

Kisspeptin is a naturally occurring reproductive hormone that serves as a crucial activator of the reproductive system. Emerging evidence from animal models shows that kisspeptin signaling has key roles in modulating reproductive behavior, including sexual motivation and erections.

In a double-blind, placebo-controlled, crossover study, the researchers enrolled 32 healthy heterosexual men (mean age, 37.9 years) who had HSDD.

At the first study visit, the men were given an infusion of kisspeptin-54 (1 nmol/kg per hour) or placebo (saline) over 75 minutes. The participants then crossed over to the other treatment at a second study visit at least 7 days later.

The active treatment significantly increased circulating kisspeptin levels. A steady state was reached after 30-75 minutes of infusion, the researchers reported.
 

Similar data in men, women

While the men viewed sexual videos, kisspeptin significantly modulated brain activity on fMRI in key structures of the sexual-processing network, compared with placebo (P = .003).

In addition, the treatment led to significant increases in penile tumescence in response to sexual stimuli (by up to 56% more than placebo; P = .02) and behavioral measures of sexual desire – most notably increased happiness about sex (P = .02).

Given the significant stimulatory effect of kisspeptin administration on penile rigidity, coupled with its demonstrated proerectile effect in rodents, future studies should examine the use of kisspeptin for patients with erectile dysfunction, the researchers wrote.

The second study included 32 women with HSDD and had the same design. Its results also showed that kisspeptin restored sexual and attraction brain processing without adverse effects.

“It is highly encouraging to see the same boosting effect in both women and men, although the precise brain pathways were slightly different, as might be expected,” coinvestigator Waljit Dhillo, PhD, Imperial College London, said in the news release.

“Collectively, the results suggest that kisspeptin may offer a safe and much-needed treatment for HSDD that affects millions of people around the world; and we look forward to taking this forward in future larger studies and in other patient groups,” Dr. Dhillo added.

The study was funded by the National Institute for Health and Care Research Imperial Biomedical Research Centre and the Medical Research Council, part of UK Research and Innovation. Dr. Comninos reported no relevant financial relationships. Dr. Dhillo reported receiving consulting fees from Myovant Sciences and KaNDy Therapeutics outside the submitted work.

At the first study visit, the men were given an infusion of kisspeptin-54 (1 nmol/kg per hour) or placebo (saline) over 75 minutes. The participants then crossed over to the other treatment at a second study visit at least 7 days later.

The active treatment significantly increased circulating kisspeptin levels. A steady state was reached after 30-75 minutes of infusion, the researchers reported.
 

Similar data in men, women

While the men viewed sexual videos, kisspeptin significantly modulated brain activity on fMRI in key structures of the sexual-processing network, compared with placebo (P = .003).

In addition, the treatment led to significant increases in penile tumescence in response to sexual stimuli (by up to 56% more than placebo; P = .02) and behavioral measures of sexual desire – most notably increased happiness about sex (P = .02).

Given the significant stimulatory effect of kisspeptin administration on penile rigidity, coupled with its demonstrated proerectile effect in rodents, future studies should examine the use of kisspeptin for patients with erectile dysfunction, the researchers wrote.

The second study included 32 women with HSDD and had the same design. Its results also showed that kisspeptin restored sexual and attraction brain processing without adverse effects.

“It is highly encouraging to see the same boosting effect in both women and men, although the precise brain pathways were slightly different, as might be expected,” coinvestigator Waljit Dhillo, PhD, Imperial College London, said in the news release.

“Collectively, the results suggest that kisspeptin may offer a safe and much-needed treatment for HSDD that affects millions of people around the world; and we look forward to taking this forward in future larger studies and in other patient groups,” Dr. Dhillo added.

The study was funded by the National Institute for Health and Care Research Imperial Biomedical Research Centre and the Medical Research Council, part of UK Research and Innovation. Dr. Comninos reported no relevant financial relationships. Dr. Dhillo reported receiving consulting fees from Myovant Sciences and KaNDy Therapeutics outside the submitted work.

The reproductive hormone kisspeptin may be a treatment option for low sexual desire in men and women, according to results from two small randomized controlled trials.

The data suggest that injections of kisspeptin can boost sexual desire in men and women and can increase penile rigidity in men.

Together, these two studies provide proof of concept for the development of kisspeptin-based therapeutics for men and women with distressing hypoactive sexual desire disorder (HSDD), study investigator Alexander Comninos, MD, PhD, Imperial College London, said in a news release.

One study was published online Feb. 3, 2022, in JAMA Network Open. The other was published in October 2022.
 

Unmet need

HSDD affects up to 10% of women and 8% of men worldwide and leads to psychological and social harm, the news release noted.

“There is a real unmet need to find new, safer, and more effective therapies for this distressing condition for both women and men seeking treatment,” Dr. Comninos said.

Members of the United States military who served in Vietnam between 1961 and 1971 risked exposure to the weaponized chemical defoliant known as Agent Orange. Among the components of Agent Orange, benzene and tetrachlorodibenzo-p-dioxin (TCDD) are known carcinogens linked to several cancers. They include multiple myeloma, Hodgkin and non-Hodgkin lymphoma, as well as bladder, prostate, and lung cancer. 

In this ReCAP, Dr Timothy O'Brien, section chief of hematology at the Louis Stokes Cleveland VA Medical Center, examines the evidence that suggests a link between service-related Agent Orange exposure and acute myeloid leukemia (AML). He discusses preclinical models that show a relationship between benzene and TCDD exposure and the development of AML. 

Dr O'Brien also explains the factors that have limited researchers' ability to positively connect Agent Orange and AML. For example, there is a dwindling cohort of affected patients to study because dioxins can lie latent in fat cells for more than a decade, delaying the development of AML. During that time, many veterans will have died from unrelated causes. 

More research is needed for veterans to receive service-connected benefits for AML diagnoses. However, as Dr O'Brien notes, the PACT Act provides coverage for veterans who developed AML after exposure to benzene-contaminated water at Camp Lejeune.

Vacuum-assisted closure (VAC) of wounds has become a foundational tool in the armamentarium of wound care specialists. Using a system consisting of a sponge, semi-occlusive barrier, and fluid collection device, VAC systems apply constant negative pressure resulting in macro and micro deformation to a wound, stabilization of the wound environment, and removal of inflammatory factors in wound fluid.¹ These conditions allow for the removal of drainage and fluid from a wound bed, reduced edema and inflammation, reduced bacterial load, recruitment of healing factors, approximation of wound edges, and increased blood flow to the wound.²

In complex, infected wounds, a variation of negative pressure wound therapy (NPWT) via the instillation of topical antibiotics (instillation VAC) has been used.³ This variation has been advantageous even in soft tissue fungal infections. Early and aggressive treatment of such infections is critical to prevent dissemination, particularly in aggressive infections, such as mucormycosis.⁴ We present a case of a patient with a mucormycosis infection of his left Achilles tendon and overlying skin who was successfully treated with surgical debridement and wound care with instillation NPWT with topical amphotericin B.

Case Presentation

A 53-year-old man underwent left Achilles tendon reconstruction with allograft after a complete tear during exercise. He had no relevant medical history and was otherwise healthy, which he attributed to working out daily. About a week after the operation, he began having incisional breakdown, prompting presentation to an emergency department. There, he received IV antibiotics along with multiple debridements. After the wound failed to improve and intra-operative cultures grew mucormycosis, he was transferred to our facility for a higher level of care. On admission, he was immediately given IV amphotericin B and scheduled for repeat debridement.

After 1 prior debridement and 10 total days of IV amphotericin, a repeat debridement was performed. After the debridement, the installation VAC was applied to the patient’s left lower extremity wound with an instilling fluid of amphotericin B and the settings as follows: smart phase instill volume, 110 mL; soak time, 3.5 hours; target pressure, 125 mm Hg; intensity, low; and VAC therapy mode, continuous. After 5 days, the wound bed appeared clean without overt signs of infection. However, due to some toxicity to healthy surrounding soft tissue, the instillation VAC was discontinued and standard NPWT was started. The patient underwent 2 additional rounds of debridement with partial delayed closure. Four weeks after discontinuation of the instillation VAC, the wound appeared healthy and granulated so the patient underwent split-thickness skin grafting to the left posterior ankle. He subsequently completed a course of oral antifungal medication as an outpatient.

The patient was seen in the outpatient clinic for 14 months from the initial mucormycosis infection (Figure).

Discussion

Mucormycosis is an infection caused by fungi in the class Zygomycetes and of the order Mucorales that typically occurs in immunocompromised patients, especially those with diabetic ketoacidosis and neutropenia. Given that this patient had no relevant medical history and was otherwise healthy, he was at extremely low risk of this type of infection. In this patient’s case, the spores of this nonseptate hyphae wide-branching species were most likely introduced at the time of left Achilles tendon repair. Mucormycosis is progressive and can be fatal unless treated, with a mortality rate approaching 70%.⁵ The rarity and heterogeneity of mucormycosis make treatment variable.⁶ No prospective or randomized clinical trials exist in plastic surgery literature.

The use of wound VAC in combination with the instillation of amphotericin B to treat cutaneous mucormycosis is not well documented. Mucormycosis infections are traditionally addressed with surgical debridement and antifungal therapy, specifically IV amphotericin B.^7,8 As previously noted, NPWT has become the gold standard in treating complex wounds.³ Additionally, wound VAC therapy with instillation has been noted in the literature as a reliable method to treat bacteria-infected wounds, providing a shorter treatment period and earlier wound closure.⁹ Instillation VAC therapy has proven particularly useful in complex, infected wounds, such as aggressive fungal infections.

Mucormycosis treatment is challenging particularly in the extremities as management must balance both mortality and limb salvage. In this case, the use of NPWT with wound VAC and intervals of instilling amphotericin B facilitated infection control in this lower extremity mucormycosis infection. The significant adverse effect profile of amphotericin B, particularly the nephrotoxicity, should be seriously considered when deciding the treatment regimen for patients affected by mucormycosis. Locally, topical amphotericin B has been reported to cause blistering, itchiness, redness, peeling, and dryness. However, topical preparations of amphotericin B are nontoxic unlike their IV counterpart, able to cross the physiological barriers of the skin while simultaneously targeting macrophages in the dermis and epidermis.¹⁰

Conclusions

Although the mainstay of treatment for systemic mucormycosis is radical debridement and IV amphotericin B, a more localized infection may benefit from an adjunct like an instillation wound VAC with topical amphotericin B, as presented in this case study. Swift treatment with wound VAC was beneficial in the overall recovery and tissue healing of this patient and may be beneficial in similar cases.

A diet high in flavonoids, such as black tea, can help prevent abdominal aortic calcification (AAC) in women later in life, according to the Heart Foundation and researchers from Edith Cowan University, Perth, Australia.

What to know

• Elderly women who drank black tea on a regular basis or consumed a high level of flavonoids in their diet were found to be far less likely to develop extensive AAC.
• AAC is calcification of the large artery that supplies oxygenated blood from the heart to the abdominal organs and lower limbs. It is associated with cardiovascular disorders, such as heart attack and stroke, as well as late-life dementia.
• Flavonoids are naturally occurring substances that regulate cellular activity. They are found in many common foods and beverages, such as black tea, green tea, apples, nuts, citrus fruit, berries, red wine, dark chocolate, and others.
• Study participants who had a higher intake of total flavonoids, flavan-3-ols, and flavonols were almost 40% less likely to have extensive AAC, while those who drank two to six cups of black tea per day had up to 42% less chance of experiencing extensive AAC.
• People who do not drink tea can still benefit by including foods rich in flavonoids in their diet, which protects against extensive calcification of the arteries.
