Use of oophorectomy for adnexal torsion has remained at approximately 70% despite guidelines advising ovarian conservation, based on data from more than 1,700 individuals.

Prompt surgical management is essential in cases of ovarian torsion in order to salvage ovarian function, and recent studies have shown that conservative management with detorsion does not increase postoperative complications, compared with oophorectomy, wrote Hannah Ryles, MD, of the University of Pennsylvania, Philadelphia, and colleagues.

The American College of Obstetricians and Gynecologists issued practice guidelines in November 2016 that recommended ovarian conservation rather than oophorectomy to manage adnexal torsion in women wishing to preserve fertility. However, the impact of this guideline on clinical practice and surgical patterns remains unclear, the researchers said.

In a study published in Obstetrics and Gynecology, the researchers reviewed data from 402 patients who underwent surgeries before the updated ACOG guidelines (2008-2016) and 1,389 who underwent surgeries after the guidelines (2017-2020). Surgery data came from the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) database. The study population included women aged 18-50 years who underwent adnexal torsion surgery and were identified as having either oophorectomy or ovarian conservation surgery.

A total of 1,791 surgeries performed for adnexal torsion were included in the study; 542 (30.3%) involved ovarian conservation and 1,249 (69.7%) involved oophorectomy.

The proportion of oophorectomies was similar during the periods before and after the guidelines (71.9% vs. 69.1%; P = .16). However, the proportion of oophorectomies changed significantly across the entire study period, by approximately –1.6% each year.

Factors significantly associated with oophorectomy compared with ovarian conservation included older age (35 years vs. 28 years), higher body mass index (29.2 kg/m² vs. 27.5 kg/m²), anemia (12.2% vs. 7.2%), hypertension (10.4% vs. 3.1%), and higher American Society of Anesthesiologists classification.

“There remains no defined acceptable rate of oophorectomy; this decision involves multiple factors, such as fertility and other patient desires after a risk and benefit discussion, menopausal status, concern for malignancy, and safety and feasibility of conservative procedures,” the researchers wrote in their discussion. However, in emergency situations, it may be difficult to determine a patient’s preferences, and a lack of desire for future fertility may be presumed, which may contribute to the relatively high oophorectomy rates over time, they said.

The findings were limited by several factors including the retrospective design and lack of data on surgical history, histopathology, and intraoperative appearance of the ovary, as well as lack of clinical data including the time from presentation to diagnosis or surgery, the researchers noted. “Although we were also unable to determine obstetric history and fertility desires, our median age of 32 years reflects a young cohort that was limited to women of reproductive age,” they added.

However, the results reflect studies suggesting that clinical practice often lags behind updated guidelines, and the findings were strengthened by the use of the NSQIP database and reflect a need for greater efforts to promote ovarian conservation in accordance with the current guidelines, the researchers concluded.
 

Consider unilateral oophorectomy

The current study highlights the discrepancy between the ACOG guidelines and clinical practice, with “disappointingly low” rates of ovarian preservation in the adult population, wrote Riley J. Young, MD, and Kimberly A. Kho, MD, both of the University of Texas Southwestern Medical Center, Dallas, in an accompanying editorial. The reasons for the discrepancy include clinical concerns for conserving a torsed ovary and the difficulty of assessing fertility desires in an emergency situation, they said.

However, consideration of unilateral oophorectomy as an option should be part of clinical decision-making, according to the editorialists. Previous studies suggest that retention of a single ovarian may still allow for a successful pregnancy, and the effects of unilateral oophorectomy have been studied in infertility and assisted reproductive technology settings.

Women with a single ovary have fewer eggs and require higher amounts of gonadotropins, but pregnancy is possible, the editorialists said. However, the long-term effects of unilateral oophorectomy are uncertain, and potential detrimental outcomes include increased mortality and cognitive impairment; therefore “we aim for premenopausal ovaries simply to be conserved, whether fertility is the stated goal or not,” they noted. This may include consideration of unilateral oophorectomy. “Each ovary conserved at midnight moves us closer to a more acceptable ovarian conservation rate,” they concluded.

The study received no outside funding. The researchers had no financial conflicts to disclose. Dr. Kho disclosed funding to her institution from Hologic for being on an investigator-initiated study, Dr. Young had no financial conflicts to disclose.

A new analysis suggests that the initial target of therapy – lung or brain – doesn’t affect overall survival rates in patients with non–small cell lung cancer that has spread to the brain.

“The findings of our study highlight the importance of adopting a personalized, case-based approach when treating each patient” instead of always treating the brain or lung first, lead author Arvind Kumar, a medical student at Icahn School of Medicine at Mount Sinai, New York, said in an interview.

The study was released at European Lung Cancer Congress 2023.

According to the author, current guidelines recommend treating the brain first in patients with non–small cell lung cancer and a tumor that has spread to the brain.

“Determining whether the brain or body gets treated first depends on where the symptoms are coming from, how severe the symptoms are, how bulky the disease is, and how long the treatment to each is expected to take,” radiation oncologist Henry S. Park, MD, MPH, chief of the thoracic radiotherapy program at Yale University, New Haven, Conn., said in an interview. “Often the brain is treated first since surgery is used for both diagnosis of metastatic disease as well as removal of the brain metastasis, especially if it is causing symptoms. The radiosurgery that follows tends to occur within a day or a few days.”

However, he said, “if the brain disease is small and not causing symptoms, and the lung disease is more problematic, then we will often treat the body first and fit in the brain treatment later.”

For the new study, researchers identified 1,044 patients in the National Cancer Database with non–small cell lung cancer and brain metastases who received systemic therapy plus surgery, brain stereotactic radiosurgery, or lung radiation. All were treated from 2010 to 2019; 79.0% received brain treatment first, and the other 21.0% received lung treatment first.

There was no statistically significant difference in overall survival between those whose brains were treated first and those whose lungs were treated first (hazard ratio, 1.24, 95% confidence interval [CI], 0.91-1.70, P = .17). A propensity score–matched analysis turned up no difference in 5-year survival (38.2% of those whose brains were treated first, 95% CI, 27.5-34.4, vs. 38.0% of those whose lungs were treated first, 95% CI, 29.9-44.7, P = .32.)

“These results were consistent regardless of which combination of treatment modalities the patient received – neurosurgery versus brain stereotactic radiosurgery, thoracic surgery versus thoracic radiation,” the author said.

He cautioned that “our study only included patients who were considered candidates for either surgery or radiation to both the brain and lung. The results of our study should therefore be cautiously interpreted for patients who may have contraindications to such treatment.”

Dr. Park, who didn’t take part in the study, said “the results are consistent with what I would generally expect.”

He added: “The take-home message for clinicians should be that there is no one correct answer in how to manage non–small cell lung cancer with synchronous limited metastatic disease in only the brain. If the brain disease is bulky and/or causes symptoms while the body disease isn’t – or if a biopsy or surgery is required to prove that the patient in fact has metastatic disease – then the brain disease should be treated first. On the other hand, if the body disease is bulky and/or causing symptoms while the brain disease isn’t – and there is no need for surgery but rather only a biopsy of the brain – then the body disease can be treated first.”

No funding was reported. The study authors and Dr. Park reported no financial conflicts or other disclosures.

At a single robotic-assisted pulmonary lobectomy center, patients with public insurance or combined public and private insurance fared worse than those with private insurance, according to a new retrospective analysis.

The study used public insurance status as a marker for low socioeconomic status (SES) and suggests that patients with combined insurance may constitute a separate population that deserves more attention.

Lower SES has been linked to later stage diagnoses and worse outcomes in NSCLC. Private insurance is a generally-accepted indicator of higher SES, while public insurance like Medicare or Medicaid, alone or in combination with private supplementary insurance, is an indicator of lower SES.

Although previous studies have found associations between patients having public health insurance and experiencing later-stage diagnoses and worse overall survival, there have been few studies of surgical outcomes, and almost no research has examined combination health insurance, according to Allison O. Dumitriu Carcoana, who presented the research during a poster session at the European Lung Cancer Congress 2023.

“This is an important insurance subgroup for us because the majority of our patients fall into this subgroup by being over 65 years old and thus qualifying for Medicare while also paying for a private supplement,” said Ms. Dumitriu Carcoana, who is a medical student at University of South Florida Health Morsani College of Medicine, Tampa.

A previous analysis by the group found an association between private insurance status and better discharge status, as well as higher 5-year overall survival. After accumulating an additional 278 patients, the researchers examined 10-year survival outcomes.

In the new analysis, 52% of 711 participants had combination insurance, while 28% had private insurance, and 20% had public insurance. The subgroups all had similar demographic and histological characteristics. The study was unique in that it found no between-group differences in higher stage at diagnosis, whereas previous studies have found a greater risk of higher stage diagnosis among individuals with public insurance. As expected, patients in the combined insurance group had a higher mean age (P less than .0001) and higher Charlson comorbidity index scores (P = .0014), which in turn was associated with lower 10-year survival. The group also had the highest percentage of former smokers, while the public insurance group had the highest percentage of current smokers (P = .0003).

At both 5 and 10 years, the private insurance group had better OS than the group with public (P less than .001) and the combination insurance group (P = .08). Public health insurance was associated with worse OS at 5 years (hazard ratio, 1.83; P less than .005) but not at 10 years (HR, 1.18; P = .51), while combination insurance was associated with worse OS at 10 years (HR, 1.72; P = .02).

“We think that patients with public health insurance having the worst 5-year overall survival, despite their lower ages and fewer comorbid conditions, compared with patients with combination insurance, highlights the impact of lower socioeconomic status on health outcomes. These patients had the same tumor characteristics, BMI, sex, and race as our patients in the other two insurance groups. The only other significant risk factor [the group had besides having a higher proportion of patients with lower socioeconomic status was that it had a higher proportion of current smokers]. But the multivariate analyses showed that insurance status was an independent predictor of survival, regardless of smoking status or other comorbidities,” said Ms. Dumitriu Carcoana.

“At 10 years post-operatively, the survival curves have shifted and the combination patients had the worst 10-year overall survival. We attribute this to their higher number of comorbid conditions and increased age. In practice, [this means that] the group of patients with public insurance type, but no supplement, should be identified clinically, and the clinical team can initiate a discussion,” Ms. Dumitriu Carcoana said.

“Do these patients feel that they can make follow-up appointments, keep up with medication costs, and make the right lifestyle decisions postoperatively on their current insurance plan? If not, can they afford a private supplement? In our cohort specifically, it may also be important to do more preoperative counseling on the importance of smoking cessation,” she added.

The study is interesting, but it has some important limitations, according to Raja Flores, MD, who was not involved with the study. The authors stated that there was no difference between the insurance groups with respect to mortality or cancer stage, which is the most important predictor of survival. However, the poster didn't include details of the authors' analysis, making it difficult to interpret, Dr. Flores said.

The fact that the study includes a single surgeon has some disadvantages in terms of broader applicability, but it also controls for surgical technique. “Different surgeons have different ways of doing things, so if you had the same surgeon doing it the same way every time, you can look at other variables like insurance (status) and stage,” said Dr. Flores.

The results may also provide an argument against using robotic surgery in patients who do not have insurance, especially since they have not been proven to be better than standard minimally invasive surgery with no robotic assistance. With uninsured patients, “you’re using taxpayer money for a more expensive procedure that isn’t proving to be any better,” Dr. Flores explained.

The study was performed at a single center and cannot prove causation due to its retrospective nature.

Ms. Dumitriu Carcoana and Dr. Flores have no relevant financial disclosures.

The fact that the study includes a single surgeon has some disadvantages in terms of broader applicability, but it also controls for surgical technique. “Different surgeons have different ways of doing things, so if you had the same surgeon doing it the same way every time, you can look at other variables like insurance (status) and stage,” said Dr. Flores.

The results may also provide an argument against using robotic surgery in patients who do not have insurance, especially since they have not been proven to be better than standard minimally invasive surgery with no robotic assistance. With uninsured patients, “you’re using taxpayer money for a more expensive procedure that isn’t proving to be any better,” Dr. Flores explained.

The study was performed at a single center and cannot prove causation due to its retrospective nature.

At a single robotic-assisted pulmonary lobectomy center, patients with public insurance or combined public and private insurance fared worse than those with private insurance, according to a new retrospective analysis.

The study used public insurance status as a marker for low socioeconomic status (SES) and suggests that patients with combined insurance may constitute a separate population that deserves more attention.

Lower SES has been linked to later stage diagnoses and worse outcomes in NSCLC. Private insurance is a generally-accepted indicator of higher SES, while public insurance like Medicare or Medicaid, alone or in combination with private supplementary insurance, is an indicator of lower SES.

Although previous studies have found associations between patients having public health insurance and experiencing later-stage diagnoses and worse overall survival, there have been few studies of surgical outcomes, and almost no research has examined combination health insurance, according to Allison O. Dumitriu Carcoana, who presented the research during a poster session at the European Lung Cancer Congress 2023.

“This is an important insurance subgroup for us because the majority of our patients fall into this subgroup by being over 65 years old and thus qualifying for Medicare while also paying for a private supplement,” said Ms. Dumitriu Carcoana, who is a medical student at University of South Florida Health Morsani College of Medicine, Tampa.

A previous analysis by the group found an association between private insurance status and better discharge status, as well as higher 5-year overall survival. After accumulating an additional 278 patients, the researchers examined 10-year survival outcomes.

In the new analysis, 52% of 711 participants had combination insurance, while 28% had private insurance, and 20% had public insurance. The subgroups all had similar demographic and histological characteristics. The study was unique in that it found no between-group differences in higher stage at diagnosis, whereas previous studies have found a greater risk of higher stage diagnosis among individuals with public insurance. As expected, patients in the combined insurance group had a higher mean age (P less than .0001) and higher Charlson comorbidity index scores (P = .0014), which in turn was associated with lower 10-year survival. The group also had the highest percentage of former smokers, while the public insurance group had the highest percentage of current smokers (P = .0003).

At both 5 and 10 years, the private insurance group had better OS than the group with public (P less than .001) and the combination insurance group (P = .08). Public health insurance was associated with worse OS at 5 years (hazard ratio, 1.83; P less than .005) but not at 10 years (HR, 1.18; P = .51), while combination insurance was associated with worse OS at 10 years (HR, 1.72; P = .02).

“We think that patients with public health insurance having the worst 5-year overall survival, despite their lower ages and fewer comorbid conditions, compared with patients with combination insurance, highlights the impact of lower socioeconomic status on health outcomes. These patients had the same tumor characteristics, BMI, sex, and race as our patients in the other two insurance groups. The only other significant risk factor [the group had besides having a higher proportion of patients with lower socioeconomic status was that it had a higher proportion of current smokers]. But the multivariate analyses showed that insurance status was an independent predictor of survival, regardless of smoking status or other comorbidities,” said Ms. Dumitriu Carcoana.

“At 10 years post-operatively, the survival curves have shifted and the combination patients had the worst 10-year overall survival. We attribute this to their higher number of comorbid conditions and increased age. In practice, [this means that] the group of patients with public insurance type, but no supplement, should be identified clinically, and the clinical team can initiate a discussion,” Ms. Dumitriu Carcoana said.

“Do these patients feel that they can make follow-up appointments, keep up with medication costs, and make the right lifestyle decisions postoperatively on their current insurance plan? If not, can they afford a private supplement? In our cohort specifically, it may also be important to do more preoperative counseling on the importance of smoking cessation,” she added.

The study is interesting, but it has some important limitations, according to Raja Flores, MD, who was not involved with the study. The authors stated that there was no difference between the insurance groups with respect to mortality or cancer stage, which is the most important predictor of survival. However, the poster didn't include details of the authors' analysis, making it difficult to interpret, Dr. Flores said.

A whole new, tiny level of hangry

Ever been so hungry that everything just got on your nerves? Maybe you feel a little snappy right now? Like you’ll just lash out unless you get something to eat? Been there. And so have bacteria.

New research shows that some bacteria go into a full-on Hulk smash if they’re not getting the nutrients they need by releasing toxins into the body. Sounds like a bacterial temper tantrum.

Rosenthal et al.

Even though two cells may be genetically identical, they don’t always behave the same in a bacterial community. Some do their job and stay in line, but some evil twins rage out and make people sick by releasing toxins into the environment, Adam Rosenthal, PhD, of the University of North Carolina and his colleagues discovered.

To figure out why some cells were all business as usual while others were not, the investigators looked at Clostridium perfringens, a bacterium found in the intestines of humans and other vertebrates. When the C. perfringens cells were fed a little acetate to munch on, the hangry cells calmed down faster than a kid with a bag of fruit snacks, reducing toxin levels. Some cells even disappeared, falling in line with their model-citizen counterparts.

So what does this really mean? More research, duh. Now that we know nutrients play a role in toxicity, it may open the door to finding a way to fight against antibiotic resistance in humans and reduce antibiotic use in the food industry.

So think to yourself. Are you bothered for no reason? Getting a little testy with your friends and coworkers? Maybe you just haven’t eaten in a while. You’re literally not alone. Even a single-cell organism can behave based on its hunger levels.

Now go have a snack. Your bacteria are getting restless.
 

The very hangry iguana?

Imagine yourself on a warm, sunny tropical beach. You are enjoying a piece of cake as you take in the slow beat of the waves lapping against the shore. Life is as good as it could be.

Then you feel a presence nearby. Hostility. Hunger. A set of feral, covetous eyes in the nearby jungle. A reptilian beast stalks you, and its all-encompassing sweet tooth desires your cake.

Wait, hold on, what?

As an unfortunate 3-year-old on vacation in Costa Rica found out, there’s at least one iguana in the world out there with a taste for sugar (better than a taste for blood, we suppose).

While out on the beach, the lizard darted out of nowhere, bit the girl on the back of the hand, and stole her cake. Still not the worst party guest ever. The child was taken to a local clinic, where the wound was cleaned and a 5-day antibiotic treatment (lizards carry salmonella) was provided. Things seemed fine, and the girl returned home without incident.

But of course, that’s not the end of the story. Five months later, the girl’s parents noticed a red bump at the wound site. Over the next 3 months, the surrounding skin grew red and painful. A trip to the hospital in California revealed that she had a ganglion cyst and a discharge of pus. Turns out our cake-obsessed lizard friend did give the little girl a gift: the first known human case of Mycobacterium marinum infection following an iguana bite on record.

M. marinum, which causes a disease similar to tuberculosis, typically infects fish but can infect humans if skin wounds are exposed to contaminated water. It’s also resistant to most antibiotics, which is why the first round didn’t clear up the infection. A second round of more-potent antibiotics seems to be working well.

So, to sum up, this poor child got bitten by a lizard, had her cake stolen, and contracted a rare illness in exchange. For a 3-year-old, that’s gotta be in the top-10 worst days ever. Unless, of course, we’re actually living in the Marvel universe (sorry, multiverse at this point). Then we’re totally going to see the emergence of the new superhero Iguana Girl in 15 years or so. Keep your eyes open.
 

No allergies? Let them give up cake

Allergy season is already here – starting earlier every year, it seems – and many people are not happy about it. So unhappy, actually, that there’s a list of things they would be willing to give up for a year to get rid of their of allergies, according to a survey conducted by OnePoll on behalf of Flonase.

Nearly 40% of 2,000 respondents with allergies would go a year without eating cake or chocolate or playing video games in exchange for allergy-free status, the survey results show. Almost as many would forgo coffee (38%) or pizza (37%) for a year, while 36% would stay off social media and 31% would take a pay cut or give up their smartphones, the Independent reported.

More than half of the allergic Americans – 54%, to be exact – who were polled this past winter – Feb. 24 to March 1, to be exact – consider allergy symptoms to be the most frustrating part of the spring. Annoying things that were less frustrating to the group included mosquitoes (41%), filing tax returns (38%), and daylight savings time (37%).

The Trump arraignment circus, of course, occurred too late to make the list, as did the big “We’re going back to the office! No wait, we’re closing the office forever!” email extravaganza and emotional roller coaster. That second one, however, did not get nearly as much media coverage.

Stereotactic body radiation therapy (SBRT) and surgery offer nearly equal overall survival rates for patients with stage I and II non–small cell lung cancer (NSCLC), according to population-based data from a German cancer registry.

“From a public health perspective, SBRT is a good therapeutic option in terms of survival, especially for elderly and inoperable patients,” noted the study authors, led by Jörg Andreas Müller, MD, department of radiation oncology, University Hospital of Halle, Germany.

The analysis was published online in the journal Strahlentherapie Und Onkologie.

Surgery remains the standard of care for early stage NSCLC. However, many patients are not eligible for surgery because of the tumor’s location, age, frailty, or comorbidities.

Before the introduction of SBRT, conventional radiation therapy was the only reasonable option for inoperable patients, with study data showing only a small survival improvement in treated vs. untreated patients.

High-precision, image-guided SBRT offers better tumor control with limited toxicity. And while many radiation oncology centers in Germany adopted SBRT as an alternative treatment for surgery after 2000, few population-based studies evaluating SBRT’s impact on overall survival exist.

Using the German clinical cancer registry of Berlin-Brandenburg, Dr. Müller and colleagues assessed SBRT as an alternative to surgery in 558 patients with stage I and II NSCLC, diagnosed between 2000 and 2015.

More patients received surgery than SBRT (74% vs. 26%). Those who received SBRT were younger than those in the surgery group and had better Karnofsky performance status.

Among patients in the SBRT group, median survival was 19 months overall and 27 months in patients over age 75. In the surgery group, median survival was 22 months overall and 24 months in those over 75.

In a univariate survival model of a propensity-matched sample of 292 patients – half of whom received SBRT – survival rates were similar among those who underwent SBRT versus surgery (hazard ratio [HR], 1.2; P = .2).

Survival was also similar in the two treatment groups in a T1 subanalysis (HR, 1.12; P = .7) as well as in patients over age 75 (HR, 0.86; P = .5).

Better performance status scores were associated with improved survival, and higher histological grades and TNM stages were linked to higher mortality risk. The availability of histological data did not have a significant impact on survival outcomes.

Overall, the findings suggest that SBRT and surgery offer comparable survival outcomes in early stage NSCLC and “the availability of histological data might not be decisive for treatment planning,” Dr. Müller and colleagues said. 

Drew Moghanaki, MD, chief of the thoracic oncology service at UCLA Health Jonsson Comprehensive Cancer Center, Los Angeles, highlighted the findings on Twitter.

A thoracic surgeon from Germany responded with several concerns about the study, including the use of statistics with univariate modeling and undiagnosed lymph node (N) status.

Dr. Moghanaki replied that these “concerns summarize how we USED to think. It increasingly seems they aren’t as important as our teachers once thought they were.  As we move into the future we need to reassess the data that supported these recommendations as they seem more academic than patient centered.”

The study authors reported no specific funding, and no relevant financial relationships.

This transcript has been edited for clarity.

“Excess deaths.” You’ve heard the phrase countless times by now. It is one of the myriad of previously esoteric epidemiology terms that the pandemic brought squarely into the zeitgeist.

As a sort of standard candle of the performance of a state or a region or a country in terms of health care, it has a lot of utility – if for nothing more than Monday-morning quarterbacking. But this week, I want to dig in on the concept a bit because, according to a new study, the excess death gap between the United States and Western Europe has never been higher.

What do we mean when we say “excess mortality?” The central connotation of the idea is that there are simply some deaths that should not have occurred. You might imagine that the best way to figure this out is for some group of intelligent people to review each death and decide, somehow, whether it was expected or not. But aside from being impractical, this would end up being somewhat subjective. That older person who died from pneumonia – was that an expected death? Could it have been avoided?

Rather, the calculation of excess mortality relies on large numbers and statistical inference to compare an expected number of deaths with those that are observed.

The difference is excess mortality, even if you can never be sure whether any particular death was expected or not.

As always, however, the devil is in the details. What data do you use to define the expected number of deaths?

There are options here. Probably the most straightforward analysis uses past data from the country of interest. You look at annual deaths over some historical period of time and compare those numbers with the rates today. Two issues need to be accounted for here: population growth – a larger population will have more deaths, so you need to adjust the historical population with current levels, and demographic shifts – an older or more male population will have more deaths, so you need to adjust for that as well.

But provided you take care of those factors, you can estimate fairly well how many deaths you can expect to see in any given period of time.

Still, you should see right away that excess mortality is a relative concept. If you think that, just perhaps, the United States has some systematic failure to deliver care that has been stable and persistent over time, you wouldn’t capture that failing in an excess mortality calculation that uses U.S. historical data as the baseline.

The best way to get around that is to use data from other countries, and that’s just what this article – a rare single-author piece by Patrick Heuveline – does, calculating excess deaths in the United States by standardizing our mortality rates to the five largest Western European countries: the United Kingdom, France, Germany, Italy, and Spain.

Controlling for the differences in the demographics of that European population, here is the expected number of deaths in the United States over the past 5 years.

“Excess deaths.” You’ve heard the phrase countless times by now. It is one of the myriad of previously esoteric epidemiology terms that the pandemic brought squarely into the zeitgeist.

As a sort of standard candle of the performance of a state or a region or a country in terms of health care, it has a lot of utility – if for nothing more than Monday-morning quarterbacking. But this week, I want to dig in on the concept a bit because, according to a new study, the excess death gap between the United States and Western Europe has never been higher.

What do we mean when we say “excess mortality?” The central connotation of the idea is that there are simply some deaths that should not have occurred. You might imagine that the best way to figure this out is for some group of intelligent people to review each death and decide, somehow, whether it was expected or not. But aside from being impractical, this would end up being somewhat subjective. That older person who died from pneumonia – was that an expected death? Could it have been avoided?

Rather, the calculation of excess mortality relies on large numbers and statistical inference to compare an expected number of deaths with those that are observed.

The difference is excess mortality, even if you can never be sure whether any particular death was expected or not.

As always, however, the devil is in the details. What data do you use to define the expected number of deaths?

There are options here. Probably the most straightforward analysis uses past data from the country of interest. You look at annual deaths over some historical period of time and compare those numbers with the rates today. Two issues need to be accounted for here: population growth – a larger population will have more deaths, so you need to adjust the historical population with current levels, and demographic shifts – an older or more male population will have more deaths, so you need to adjust for that as well.

But provided you take care of those factors, you can estimate fairly well how many deaths you can expect to see in any given period of time.

Still, you should see right away that excess mortality is a relative concept. If you think that, just perhaps, the United States has some systematic failure to deliver care that has been stable and persistent over time, you wouldn’t capture that failing in an excess mortality calculation that uses U.S. historical data as the baseline.

Getting sweet on sweat

Are you the sort of person who struggles in social situations? Have the past 3 years been a secret respite from the terror and exhaustion of meeting new people? We understand your plight. People kind of suck. And you don’t have to look far to be reminded of it.

Unfortunately, on occasion we all have to interact with other human beings. If you suffer from social anxiety, this is not a fun thing to do. But new research indicates that there may be a way to alleviate the stress for those with social anxiety: armpits.

Specifically, sweat from the armpits of other people. Yes, this means a group of scientists gathered up some volunteers and collected their armpit sweat while the volunteers watched a variety of movies (horror, comedy, romance, etc.). Our condolences to the poor unpaid interns tasked with gathering the sweat.

Once they had their precious new medicine, the researchers took a group of women and administered a round of mindfulness therapy. Some of the participants then received the various sweats, while the rest were forced to smell only clean air. (The horror!) Lo and behold, the sweat groups had their anxiety scores reduced by about 40% after their therapy, compared with just 17% in the control group.

The researchers also found that the source of the sweat didn’t matter. Their study subjects responded the same to sweat excreted during a scary movie as they did to sweat from a comedy, a result that surprised the researchers. They suggested chemosignals in the sweat may affect the treatment response and advised further research. Which means more sweat collection! They plan on testing emotionally neutral movies next time, and if we can make a humble suggestion, they also should try the sweatiest movies.

Before the Food and Drug Administration can approve armpit sweat as a treatment for social anxiety, we have some advice for those shut-in introverts out there. Next time you have to interact with rabid extroverts, instead of shaking their hands, walk up to them and take a deep whiff of their armpits. Establish dominance. Someone will feel awkward, and science has proved it won’t be you.
 

The puff that vaccinates

Ever been shot with a Nerf gun or hit with a foam pool tube? More annoying than painful, right? If we asked if you’d rather get pelted with one of those than receive a traditional vaccine injection, you would choose the former. Maybe someday you actually will.

Dr. Jeremiah Gassensmith

During the boredom of the early pandemic lockdown, Jeremiah Gassensmith, PhD, of the department of chemistry and biochemistry at the University of Texas, Dallas, ordered a compressed gas–powered jet injection system to fool around with at home. Hey, who didn’t? Anyway, when it was time to go back to the lab he handed it over to one of his grad students, Yalini Wijesundara, and asked her to see what could be done with it.

In her tinkering she found that the jet injector could deliver metal-organic frameworks (MOFs) that can hold a bunch of different materials, like proteins and nucleic acids, through the skin.

Thus the “MOF-Jet” was born!

Jet injectors are nothing new, but they hurt. The MOF-Jet, however, is practically painless and cheaper than the gene guns that veterinarians use to inject biological cargo attached to the surface of a metal microparticle.

Changing the carrier gas also changes the time needed to break down the MOF and thus alters delivery of the drug inside. “If you shoot it with carbon dioxide, it will release its cargo faster within cells; if you use regular air, it will take 4 or 5 days,” Ms. Wijesundara explained in a written statement. That means the same drug could be released over different timescales without changing its formulation.

While testing on onion cells and mice, Ms. Wijesundara noted that it was as easy as “pointing and shooting” to distribute the puff of gas into the cells. A saving grace to those with needle anxiety. Not that we would know anything about needle anxiety.

More testing needs to be done before bringing this technology to human use, obviously, but we’re looking forward to saying goodbye to that dreaded prick and hello to a puff.
 

Your hippocampus is showing

Brain anatomy is one of the many, many things that’s not really our thing, but we do know a cool picture when we see one. Case in point: The image just below, which happens to be a full-scale, single-cell resolution model of the CA1 region of the hippocampus that “replicates the structure and architecture of the area, along with the position and relative connectivity of the neurons,” according to a statement from the Human Brain Project.

Dr. Michele Migliore

“We have performed a data mining operation on high resolution images of the human hippocampus, obtained from the BigBrain database. The position of individual neurons has been derived from a detailed analysis of these images,” said senior author Michele Migliore, PhD, of the Italian National Research Council’s Institute of Biophysics in Palermo.

Yes, he did say BigBrain database. BigBrain is – we checked and it’s definitely not this – a 3D model of a brain that was sectioned into 7,404 slices just 20 micrometers thick and then scanned by MRI. Digital reconstruction of those slices was done by supercomputer and the results are now available for analysis.

Dr. Migliore and his associates developed an image-processing algorithm to obtain neuronal positioning distribution and an algorithm to generate neuronal connectivity by approximating the shapes of dendrites and axons. (Our brains are starting to hurt just trying to write this.) “Some fit into narrow cones, others have a broad complex extension that can be approximated by dedicated geometrical volumes, and the connectivity to nearby neurons changes accordingly,” explained lead author Daniela Gandolfi of the University of Modena (Italy) and Reggio Emilia.

The investigators have made their dataset and the extraction methodology available on the EBRAINS platform and through the Human Brain Project and are moving on to other brain regions. And then, once everyone can find their way in and around the old gray matter, it should bring an end to conversations like this, which no doubt occur between male and female neuroscientists every day:

“Arnold, I think we’re lost.”

“Don’t worry, Bev, I know where I’m going.”

“Stop and ask this lady for directions.”

“I said I can find it.”

“Just ask her.”

“Fine. Excuse me, ma’am, can you tell us how to get to the corpora quadrigemina from here?

Borderline ovarian tumors (BOTs) are estimated to comprise 10%-15% of all epithelial tumors of the ovary. They are characterized by their behavior, which falls somewhere between benign ovarian masses and frank carcinomas. They have cytologic characteristics suggesting malignancy, such as higher cellular proliferation and more variable nuclear atypia, but, unlike carcinomas, they lack destructive stromal invasion. For decades after their recognition by the International Federation of Gynecology and Obstetrics in 1971, these tumors were classified as being of low malignant potential (and subsequently referred to as LMP tumors of the ovary). Beginning with the 2014 World Health Organization classification, the recommended terminology is now borderline tumor of the ovary.

The primary treatment for BOTs is surgery. With a mean age at diagnosis in the fifth decade, many patients with BOTs desire ovarian preservation to maintain fertility and/or prevent surgical menopause. This raises multiple questions regarding the use of fertility-sparing surgery for BOTs: What types of procedures are safe and should be offered? For those patients who undergo fertility-sparing surgery initially, is additional surgery indicated after completion of childbearing or at an age closer to natural menopause? What should this completion surgery include?

Ovarian-sparing surgery

The diagnosis of a BOT is frequently only confirmed after the decision for ovarian conservation has been made. What should be considered before electing to proceed with ovarian cystectomy instead of unilateral salpingo-oophorectomy (USO)?

Is the risk of recurrence higher with cystectomy versus oophorectomy?

Yes. The risk of recurrence of BOT appears to be higher after cystectomy than it is after oophorectomy. There is a large range reported in the literature, with the risk of recurrence after cystectomy described as between 12% and 58%. Most studies report recurrences between 25% and 35% of patients who undergo cystectomy. In contrast, the risk of recurrence after USO is often reported to be approximately 10%. Higher risk of recurrence after cystectomy is speculated to be due to leaving some BOT at the time of initial surgery.

Multiple meta-analyses have found an increased risk of recurrence after cystectomy. The risk of recurrence after unilateral cystectomy was 19.4%, compared with 9.1% after USO, in 2,145 patients included in a 2017 meta-analysis.¹ Similarly, a 2021 meta-analysis found a significantly higher rate of BOT recurrence in patients who underwent unilateral or bilateral cystectomy compared with USO (odds ratio, 2.02; 95% confidence interval, 1.59-2.57).²
 

Does the higher recurrence risk translate into a difference in long-term outcomes?

No. Despite an increased risk of recurrence after cystectomy, ovarian-sparing surgery does not appear to alter patients’ survival. The pooled mortality estimate was 1.6% for those undergoing fertility-sparing surgery (95% CI, 0.011-0.023), compared with 2.0% for those undergoing radical surgery (95% CI, 0.014-0.029), in a 2015 meta-analysis of over 5,100 patients. The analysis included studies in which patients underwent unilateral cystectomy, bilateral cystectomy, USO, or USO plus contralateral cystectomy. The low mortality rate did not allow for comparison between the different types of fertility-sparing surgeries.³

Do we accept a higher risk of recurrence with ovarian sparing surgery to improve fertility?

Data are mixed. When we examine studies describing fertility rates after conservative surgery, there are significant limitations to interpreting the data available. Some studies do not differentiate among patients who underwent fertility-sparing surgery, or between those who had cystectomy versus USO. Other studies do not report the number of patients who tried to achieve pregnancy after surgery. Conception rates are reported to be as high as 88.2%, which was in 116 patients who were able to be reached after fertility-sparing surgery (retained at least one ovary). Of the 51 patients who tried to conceive, 45 were successful.⁴

Multiple studies and meta-analyses have shown no difference in postoperative pregnancy rates when comparing oophorectomy to cystectomy. For instance, in a 2021 meta-analysis, there was no significant difference noted in pregnancy rates between patients who underwent USO versus cystectomy (OR, 0.92; 95% CI, 0.60-1.42).

There are some data that support improved postoperative pregnancy rates in more conservative surgery, especially in the setting of bilateral BOT. In a small study of 32 patients who had laparoscopic staging for bilateral BOTs, patients were randomized to unilateral oophorectomy plus contralateral cystectomy or to bilateral cystectomy, which was referred to as ultraconservative surgery. The time to first recurrence was shorter in the ultraconservative group (although this lost significance when regression analysis was performed), but the time to first live birth was shorter and the relative chance of having a baby was higher in the bilateral cystectomy group.⁵

Ovarian-sparing procedures should be offered to patients in the setting of BOT. With ovarian-sparing surgery, it is important to counsel patients about the increased risk of recurrence and need for long-term follow-up. Pregnancy rates are generally good after fertility-sparing surgery. Surgery to conserve both ovaries does not seem to improve pregnancy rates in the setting of unilateral BOTs.

The pooled mortality estimate was 1.6% for those undergoing fertility-sparing surgery (95% CI, 0.011-0.023), compared with 2.0% for those undergoing radical surgery (95% CI, 0.014-0.029), in a 2015 meta-analysis of over 5,100 patients. The analysis included studies in which patients underwent unilateral cystectomy, bilateral cystectomy, USO, or USO plus contralateral cystectomy. The low mortality rate did not allow for comparison between the different types of fertility-sparing surgeries.³

Do we accept a higher risk of recurrence with ovarian sparing surgery to improve fertility?

Data are mixed. When we examine studies describing fertility rates after conservative surgery, there are significant limitations to interpreting the data available. Some studies do not differentiate among patients who underwent fertility-sparing surgery, or between those who had cystectomy versus USO. Other studies do not report the number of patients who tried to achieve pregnancy after surgery. Conception rates are reported to be as high as 88.2%, which was in 116 patients who were able to be reached after fertility-sparing surgery (retained at least one ovary). Of the 51 patients who tried to conceive, 45 were successful.⁴

Multiple studies and meta-analyses have shown no difference in postoperative pregnancy rates when comparing oophorectomy to cystectomy. For instance, in a 2021 meta-analysis, there was no significant difference noted in pregnancy rates between patients who underwent USO versus cystectomy (OR, 0.92; 95% CI, 0.60-1.42).

There are some data that support improved postoperative pregnancy rates in more conservative surgery, especially in the setting of bilateral BOT. In a small study of 32 patients who had laparoscopic staging for bilateral BOTs, patients were randomized to unilateral oophorectomy plus contralateral cystectomy or to bilateral cystectomy, which was referred to as ultraconservative surgery. The time to first recurrence was shorter in the ultraconservative group (although this lost significance when regression analysis was performed), but the time to first live birth was shorter and the relative chance of having a baby was higher in the bilateral cystectomy group.⁵

Ovarian-sparing procedures should be offered to patients in the setting of BOT. With ovarian-sparing surgery, it is important to counsel patients about the increased risk of recurrence and need for long-term follow-up. Pregnancy rates are generally good after fertility-sparing surgery. Surgery to conserve both ovaries does not seem to improve pregnancy rates in the setting of unilateral BOTs.

Borderline ovarian tumors (BOTs) are estimated to comprise 10%-15% of all epithelial tumors of the ovary. They are characterized by their behavior, which falls somewhere between benign ovarian masses and frank carcinomas. They have cytologic characteristics suggesting malignancy, such as higher cellular proliferation and more variable nuclear atypia, but, unlike carcinomas, they lack destructive stromal invasion. For decades after their recognition by the International Federation of Gynecology and Obstetrics in 1971, these tumors were classified as being of low malignant potential (and subsequently referred to as LMP tumors of the ovary). Beginning with the 2014 World Health Organization classification, the recommended terminology is now borderline tumor of the ovary.

The primary treatment for BOTs is surgery. With a mean age at diagnosis in the fifth decade, many patients with BOTs desire ovarian preservation to maintain fertility and/or prevent surgical menopause. This raises multiple questions regarding the use of fertility-sparing surgery for BOTs: What types of procedures are safe and should be offered? For those patients who undergo fertility-sparing surgery initially, is additional surgery indicated after completion of childbearing or at an age closer to natural menopause? What should this completion surgery include?

Ovarian-sparing surgery

The diagnosis of a BOT is frequently only confirmed after the decision for ovarian conservation has been made. What should be considered before electing to proceed with ovarian cystectomy instead of unilateral salpingo-oophorectomy (USO)?

Is the risk of recurrence higher with cystectomy versus oophorectomy?

Yes. The risk of recurrence of BOT appears to be higher after cystectomy than it is after oophorectomy. There is a large range reported in the literature, with the risk of recurrence after cystectomy described as between 12% and 58%. Most studies report recurrences between 25% and 35% of patients who undergo cystectomy. In contrast, the risk of recurrence after USO is often reported to be approximately 10%. Higher risk of recurrence after cystectomy is speculated to be due to leaving some BOT at the time of initial surgery.

Multiple meta-analyses have found an increased risk of recurrence after cystectomy. The risk of recurrence after unilateral cystectomy was 19.4%, compared with 9.1% after USO, in 2,145 patients included in a 2017 meta-analysis.¹ Similarly, a 2021 meta-analysis found a significantly higher rate of BOT recurrence in patients who underwent unilateral or bilateral cystectomy compared with USO (odds ratio, 2.02; 95% confidence interval, 1.59-2.57).²

BOSTON – Women with breast cancer who have several tumors in one breast do not necessarily need to have a mastectomy, as new data show a low risk of recurrence at 5 years when they are treated with breast-conserving therapy and radiation.

“[The study] proves the oncologic safety of breast conservation in women with two or three sites of disease, making this a very reasonable option for (previously reluctant) surgeons to present to patients,” first author Kari Rosenkranz, MD, an associate professor at Dartmouth Health in Norwich, Vt., said in an interview.

The findings were presented here at the International Conference on Surgical Cancer Care (SSO 2023), and were published online in the Journal of Clinical Oncology.

Commenting on the study, Hiram S. Cody III, MD, an attending surgeon and professor of surgery at Weill Cornell Medicine, Memorial Sloan Kettering Cancer Center, in New York, said the findings provide valuable new evidence on the issue.

“This is an important study confirming that breast conservation is feasible and safe for women with multiple ipsilateral breast cancers, with excellent results comparable to those for women with unifocal (single site) disease,” he said in an interview.

Although there have been as many as seven previous randomized trials that have shown identical outcomes in survival and local control of disease with breast-conserving therapy versus mastectomy, all those studies excluded patients with more than one site of disease.

At present, many surgeons and guidelines continue to recommend mastectomy for women with multiple-site tumors, based on older data that showed higher recurrence rates.

That is why the new study is so important, Dr. Cody explained. “Here, we see in a prospective trial that breast-conserving therapy is feasible for those with more than one site of disease as well, with high survival and very low rates of local recurrence,” he emphasized.

Dr. Cody noted that “the ideal candidate would be a woman with relatively small tumor size and a breast large enough that the multiple excisions could be performed with a good cosmetic result.”

“We have followed this approach for some time and hope that with the publication of these results more surgeons will recommend this approach for suitable patients,” he said.

The new results were also highlighted in a press release from Mayo Clinic highlighting the Journal of Clinical Oncology publication. Lead author of the article, surgical oncologist Judy Boughey, MD, from the Mayo Clinic in Rochester, Minn., commented: “I am excited about these findings because it will empower patients and the multidisciplinary care teams caring for patients to be thinking about this option for women who may want to preserve their breast.”

This study showed the rate of cancer local recurrence was 3.1%, she noted. This is an excellent outcome and is similar to the local recurrence rate for patients with a single tumor in a breast who had breast-conserving therapy, Dr. Boughey said.

Historically, women with multiple tumors in one breast have been advised to have a mastectomy. Now, patients can be offered a less invasive option with faster recovery, resulting in better patient satisfaction and cosmetic outcomes, she added.


 

Study details

This study, known as the ACOSOG (Alliance) Z11102 trial, was a phase 2 trial conducted in 204 patients enrolled between 2012 and 2016 who had two or three sites of biopsy-proven breast cancer (each site less rhan 5 cm in size, with cN0 or cN1 disease).

These patients were a median age of 61 years, and 83.5% were ER-positive/HER2-negative, 11.5% were HER2-positive, 5.0% were ER-negative/HER2-negative, and 77.5% were node-negative.

All patients were treated with breast conservation surgery, including lumpectomy resected to negative margins, followed by whole breast radiation with a cavity boost to all lumpectomy beds.

With a median follow-up of 66.4 months, six patients developed local recurrence, with five of the recurrences occurring in the ipsilateral breast and one in the chest wall.

For the primary endpoint, the six recurrences represented an estimated cumulative incidence of local recurrence of 3.1% (95% CI, 1.3-6.4), well below the cutoff of 8% that was determined to be the acceptable 5-year local recurrence rate based on historic recurrence rates for unifocal disease, Dr. Rosenkranz explained.

There were no cases of synchronous local and distant recurrences, six contralateral breast cancers, and three new primary nonbreast cancers. Eight patients died, including one related to breast cancer.

There were no significant associations between risk of local recurrence and factors including patient age, number of sites of preoperative biopsy-proven breast cancer, HER2 status, and pathologic T and N category.

In terms of secondary endpoints, 14 patients (7.1%) converted to mastectomy because of positive margins, while 67.6% achieved margin-negative excision in a single operation.

Regarding cosmesis, 70.6% of patients reported good or excellent cosmetic outcomes at 2 years.

In terms of adherence, the whole breast radiation therapy protocol was feasible in most patients.

Of note, among patients without a breast preoperative MRI, the 5-year rate of local recurrence was significantly higher, at 22.6% (n = 14) at 5 years, compared with 1.7% among the 180 patients who did have a preoperative MRI (P = .002). However, Dr. Rosenkranz said these differences should be interpreted with caution.

“We may look at these data and think we should consider preoperative breast MRI in patients who do have known multiple ipsilateral breast cancer, although I think this cohort was certainly much too small to draw definitive conclusions, and this was not a planned secondary endpoint of the trial,” she said during her presentation.
 

Most prefer breast conservation, when possible

Overall, the findings are important considering the array of known benefits of breast conservation over mastectomy, Dr. Rosenkranz concluded.

“The reason this is so important is that we know that patients who undergo breast conservation report improved quality of life, self-esteem, and body image, and therefore it’s incumbent on us as surgeons to expand the indications for breast conservation where we can,” she told the audience.

Speaking with this news organization, she added that the decision-making around breast conservation versus mastectomy can be complicated, and some women do opt for mastectomy because of a variety of factors; therefore, “tailoring therapy to the individual goals and priorities in addition to the disease characteristics is critical.”

That said, she added that “the majority of patients who are eligible for breast conservation do prefer this option.”

Dr. Rosenkranz and Dr. Cody have reported no relevant financial relationships.

Surgeons who accept vacations and other freebies from medical device companies could face penalties like fines, stricter oversight, and even jail time, according to experts familiar with the federal Anti-Kickback Statute.

Historically, enforcement actions have primarily focused on the person or organization offering the perks – and not necessarily the physicians accepting it, Steven W. Ortquist, founder and principal of Arete Compliance Solutions, LLC, in Phoenix, told this news organization.

But that’s changing.

“In recent years, we are seeing a trend toward holding physicians and others on the receiving end of the inducement accountable as well,” said Mr. Ortquist, who is a past board member and president of the Health Care Compliance Association. He noted that authorities usually pursue the inducing company first before moving on to individual clinicians or practices.

The Department of Justice followed a similar pattern in a recently announced kickback settlement that ensnared an intraocular lens distributor, an ophthalmology equipment supplier, two CEOs, and a surgeon. Precision Lens must pay more than $43 million for offering high-end vacations and other expensive perks to surgeons who used its cataract products.

The verdict marks the end of a 6-week civil jury trial, where evidence emerged that Paul Ehlen, owner of Precision Lens and its parent company, Cameron-Ehlen Group, maintained a secret “slush fund” for paying kickbacks to ophthalmic surgeons. The inducement scheme netted the Minnesota-based company millions in sales and led to the submission of 64,575 false Medicare claims from 2006 to 2015, a violation of the Anti-Kickback Statute and the False Claims Act.

According to court documents, physicians received luxury travel and entertainment packages, including skiing, fishing, and golfing excursions at exclusive destinations, often traveling via private jet to attend Broadway musicals and major sporting events. Mr. Ehlen and company representatives also sold frequent flyer miles to physicians at a steep discount, allowing them to take personal and business trips below fair market value.

Federal authorities initially announced an investigation into the business practices of Precision Lens in 2017 after receiving a whistleblower complaint from Kipp Fesenmaier, a former executive at Sightpath Medical, an ophthalmology supplier and “corporate partner” of Precision Lens. Mr. Fesenmaier alleged that both companies were involved in an inducement scheme.

Sightpath Medical and its CEO, James Tiffany, agreed to a $12 million settlement to resolve the kickback allegations.

The Department of Justice subsequently investigated Jitendra Swarup, MD, an ophthalmologist and cataract surgeon who allegedly received “unlawful remuneration from Sightpath, Precision, and Ehlen” and filed false insurance claims. In addition to accepting expensive hunting and fishing trips from the medical device companies, Dr. Swarup was paid more than $100,000 per year for consulting services he did not fully render.

Dr. Swarup agreed to a nearly $3 million settlement and participation in a 3-year corporate integrity agreement with the Office of Inspector General. In exchange for compliance with such contracts, the OIG permits physicians to continue participating in Medicare, Medicaid, and other federal health care programs.

In a statement from attorneys, Precision Lens and Mr. Ehlen pledged to appeal the verdict and “defend ... our wholly appropriate actions” while remaining focused on their commitment to health care clinicians and manufacturers.
 

‘Endless’ opportunities for inducement

Unfortunately, opportunities for inducement are “endless,” experts say. Extravagant trips, dinners, and gifts can trigger a violation, but so can nearly anything of value.

Just last year, Biotronik reached a $12.95 million settlement amid allegations that company representatives wined and dined physicians to induce their use of its pacemakers and defibrillators. To date, no physicians have been charged.

But after a record-breaking number of whistleblower judgments last fiscal year totaling more than $2 billion, physicians should take note, Radha Bhatnagar, Esq, director of compliance at The CM Group, told the news organization.

“When manufacturers offer physicians kickbacks with the added element of fraudulent Medicare or Medicaid reimbursements, that is typically when manufacturers and individuals face civil and criminal liability,” said Ms. Bhatnagar, something the Department of Justice alluded to when announcing a settlement involving 15 Texas physicians last year.

In another case, Kingsley R. Chin, an orthopedic surgeon and designer of a spinal implant, was indicted in 2021 for paying millions of dollars in sham consulting fees to physicians who used his products. At least six surgeons who accepted money from Dr. Chin were later named in a civil case and ordered to pay $3.3 million in penalties.

Jason Montone, DO, an orthopedic surgeon who accepted the illicit payments, agreed to a plea deal with a reduced prison sentence, 1 year of supervised release, and a fine of $379,000.

Although Dr. Chin’s sentencing hasn’t been announced, violating kickback laws can result in a sentence of up to 10 years.

The verdict marks the end of a 6-week civil jury trial, where evidence emerged that Paul Ehlen, owner of Precision Lens and its parent company, Cameron-Ehlen Group, maintained a secret “slush fund” for paying kickbacks to ophthalmic surgeons. The inducement scheme netted the Minnesota-based company millions in sales and led to the submission of 64,575 false Medicare claims from 2006 to 2015, a violation of the Anti-Kickback Statute and the False Claims Act.

According to court documents, physicians received luxury travel and entertainment packages, including skiing, fishing, and golfing excursions at exclusive destinations, often traveling via private jet to attend Broadway musicals and major sporting events. Mr. Ehlen and company representatives also sold frequent flyer miles to physicians at a steep discount, allowing them to take personal and business trips below fair market value.

Federal authorities initially announced an investigation into the business practices of Precision Lens in 2017 after receiving a whistleblower complaint from Kipp Fesenmaier, a former executive at Sightpath Medical, an ophthalmology supplier and “corporate partner” of Precision Lens. Mr. Fesenmaier alleged that both companies were involved in an inducement scheme.

Sightpath Medical and its CEO, James Tiffany, agreed to a $12 million settlement to resolve the kickback allegations.

The Department of Justice subsequently investigated Jitendra Swarup, MD, an ophthalmologist and cataract surgeon who allegedly received “unlawful remuneration from Sightpath, Precision, and Ehlen” and filed false insurance claims. In addition to accepting expensive hunting and fishing trips from the medical device companies, Dr. Swarup was paid more than $100,000 per year for consulting services he did not fully render.

Dr. Swarup agreed to a nearly $3 million settlement and participation in a 3-year corporate integrity agreement with the Office of Inspector General. In exchange for compliance with such contracts, the OIG permits physicians to continue participating in Medicare, Medicaid, and other federal health care programs.

In a statement from attorneys, Precision Lens and Mr. Ehlen pledged to appeal the verdict and “defend ... our wholly appropriate actions” while remaining focused on their commitment to health care clinicians and manufacturers.
 

‘Endless’ opportunities for inducement

Unfortunately, opportunities for inducement are “endless,” experts say. Extravagant trips, dinners, and gifts can trigger a violation, but so can nearly anything of value.

Just last year, Biotronik reached a $12.95 million settlement amid allegations that company representatives wined and dined physicians to induce their use of its pacemakers and defibrillators. To date, no physicians have been charged.

But after a record-breaking number of whistleblower judgments last fiscal year totaling more than $2 billion, physicians should take note, Radha Bhatnagar, Esq, director of compliance at The CM Group, told the news organization.

“When manufacturers offer physicians kickbacks with the added element of fraudulent Medicare or Medicaid reimbursements, that is typically when manufacturers and individuals face civil and criminal liability,” said Ms. Bhatnagar, something the Department of Justice alluded to when announcing a settlement involving 15 Texas physicians last year.

In another case, Kingsley R. Chin, an orthopedic surgeon and designer of a spinal implant, was indicted in 2021 for paying millions of dollars in sham consulting fees to physicians who used his products. At least six surgeons who accepted money from Dr. Chin were later named in a civil case and ordered to pay $3.3 million in penalties.

Jason Montone, DO, an orthopedic surgeon who accepted the illicit payments, agreed to a plea deal with a reduced prison sentence, 1 year of supervised release, and a fine of $379,000.

Although Dr. Chin’s sentencing hasn’t been announced, violating kickback laws can result in a sentence of up to 10 years.

Surgeons who accept vacations and other freebies from medical device companies could face penalties like fines, stricter oversight, and even jail time, according to experts familiar with the federal Anti-Kickback Statute.

Historically, enforcement actions have primarily focused on the person or organization offering the perks – and not necessarily the physicians accepting it, Steven W. Ortquist, founder and principal of Arete Compliance Solutions, LLC, in Phoenix, told this news organization.

But that’s changing.

“In recent years, we are seeing a trend toward holding physicians and others on the receiving end of the inducement accountable as well,” said Mr. Ortquist, who is a past board member and president of the Health Care Compliance Association. He noted that authorities usually pursue the inducing company first before moving on to individual clinicians or practices.
