DENVER — In addition to the established gastrointestinal side effects common with the highly effective anti-obesity drugs, there is growing discussion around their potential to contribute to the loss of lean mass, necessary to keep the metabolic engine running full-steam.

And although measures should be recommended to prevent those effects, experts also want to remind clinicians that the loss of lean mass is indeed expected with most weight loss interventions — when they’re successful.

“The bottom line is if you’re successful with weight loss, it’s a normal process that you’re going to lose some lean mass,” Angela Fitch, MD, associate director of the Massachusetts General Hospital Weight Center in Boston, said during a presentation on the issue at Obesity Medicine 2024.

“It’s what we would expect to see if you successfully lost weight with bariatric surgery or with an intense lifestyle intervention,” said Dr. Fitch, past president of the Obesity Medicine Association.

“The difference is, there haven’t been nearly as many people being successful with weight loss with those other interventions,” she noted. “But with the popularity of the glucagon-like peptide 1 (GLP-1) medications, people are hearing this for the first time and saying, ‘Oh my gosh, 30% of the weight loss is muscle mass — that’s horrible.’ “

An underlying goal in the treatment of obesity is the reduction of fat mass, and significant fat mass reduction can provide benefits exceeding the drawbacks resulting from lean mass loss, which have been reported in clinical trials of the GLP-1s semaglutide and the dual glucose-dependent insulinotropic polypeptide tirzepatide to range from about 25% to 40%, respectively, of weight loss.

“Excess adiposity is what makes us sick — not our weight,” Dr. Fitch underscored. “The amount of fat that people are losing [with anti-obesity medications] is far more beneficial than maybe the potential that they’ve lost a little bit of lean mass,” she said.

She cited research suggesting that significant weight loss from bariatric surgery is linked to increases in life expectancy, cardiovascular risk reduction, cancer risk reduction, and a wide array of other positive effects — despite the loss of lean mass that occurs with the weight loss.

Opportunity for Awareness

The increased attention on issues of body composition accompanying weight loss importantly provides clinicians the chance to underscore to patients the importance of offsetting the loss of lean mass through strength training, nutritional choices, and other measures.

However, patients should be prepared that achieving these goals can be more challenging than expected, said Dr. Fitch.

“It can be very hard to be in an energy deficit (due to a weight loss regimen) and gain muscle mass,” she said. “When athletes are trying to gain muscle mass, they’re increasing their intake to do so. It doesn’t come naturally in today’s world.”

Nevertheless, patients can be reassured that the losses can be reversed with some effort, Dr. Fitch noted.

She cautioned that for those who succeed in building or rebuilding lean mass, the evidence may be reflected on the scale, with numbers going up, not down — something they may not wish to see.

“Patients tend to freak out when they see the scale going up after losing all of that weight, but you can reassure them that it’s okay — this is healthier weight gain.”

Special Considerations in Older Patients

Efforts at staving off lean mass loss are particularly important in older patients, who are already most vulnerable to experiencing it naturally with age, even if not on a weight loss regimen.

But Dr. Fitch offered that age does not necessarily have to be a barrier in tackling those effects.

She described two cases of treating patients in their mid-70s, a male and female, with GLP-1s for obesity. Not only were they able to achieve substantial reductions in body mass index over nearly a year on treatment, but they were also able to avoid skeletal muscle mass loss during a period when it would have likely naturally occurred.

She noted the need to augment strength training with protein intake to help build muscle, citing recommendations including consumption of 1.4-2.0 g of protein per kg of body weight for building muscle and maintaining muscle mass.

Importantly, “make sure patients aren’t too appetite suppressed so they can keep up with their nutrition,” Dr. Fitch said.

A key condition to watch for in these patients is sarcopenia. Definitions of sarcopenia vary, but it is distinguished by low skeletal muscle mass and either low muscle strength — measured, for instance, with hand grip — or low muscle performance, such as reduced walking speed or muscle power, Dr. Fitch said.

In such cases, patients may need special considerations, including avoiding significant caloric deficits and whether the risks of medication outweigh the benefits.

‘Super-Responders’ and Other Lean Mass Loss Scenarios

Further addressing the issues of body composition and weight loss at the meeting, Robert F. Kushner, MD, professor of medicine and medicine education at Northwestern University in Chicago, noted that one area of concern regarding lean mass loss is “super-responders” — patients who have exceptionally high weight loss on GLP-1s.

“We are concerned about individuals who experience very high weight loss responses to medication, [specifically] 25% or more weight loss, as well as individuals at higher risk of losing lean body mass [muscle mass], specifically people in their 50s, 60s, and 70s,” Dr. Kushner told this news organization.

“Lifestyle counseling, particularly regarding safety and body composition, is recommended in these patients,” he said, adding that in managing these patients, “the approach is to use close patient monitoring, dose reduction if needed, and emphasizing a high-protein diet accompanied by aerobic and resistance physical activity.”

Potentially dramatic lean mass loss can occur in obesity whether or not patients are on obesity medications. As evidence of this, Dr. Kushner cited a subanalysis of the Look AHEAD trial of 1019 overweight or obese patients who had a mean age of 58 years at baseline. Patients were randomized to either a physical activity and reduced calorie intervention group or simply education.

Although the results showed that fat losses in the intervention group were generally regained over 8 years, a striking, steady decline was observed in lean mass in both the intervention and control groups, including men and women.

Dr. Fitch disclosed ties to Eli Lilly, Novo Nordisk, Currax, Vivus, SideKick Health, Jenny Craig, Carmot, and Seca. Dr. Kushner is on the advisory boards of Novo Nordisk, Weight Watchers, Lilly, Boehringer Ingelheim, and Altimmune.

Observational studies on red meat consumption and lifespan are prime examples of attempts to find signal in a sea of noise. 

Randomized controlled trials are the best way to sort cause from mere correlation. But these are not possible in most matters of food consumption. So, we look back and observe groups with different exposures.

My most frequent complaint about these nonrandom comparison studies has been the chance that the two groups differ in important ways, and it’s these differences — not the food in question — that account for the disparate outcomes.

But selection biases are only one issue. There is also the matter of analytic flexibility. Observational studies are born from large databases. Researchers have many choices in how to analyze all these data.

A few years ago, Brian Nosek, PhD, and colleagues elegantly showed that analytic choices can affect results. His Many Analysts, One Data Set study had little uptake in the medical community, perhaps because he studied a social science question.
 

Multiple Ways to Slice the Data

Recently, a group from McMaster University, led by Dena Zeraatkar, PhD, has confirmed the analytic choices problem, using the question of red meat consumption and mortality. 

Their idea was simple: Because there are many plausible and defensible ways to analyze a dataset, we should not choose one method; rather, we should choose thousands, combine the results, and see where the truth lies. 

You might wonder how there could be thousands of ways to analyze a dataset. I surely did. 

The answer stems from the choices that researchers face. For instance, there is the selection of eligible participants, the choice of analytic model (logistic, Poisson, etc.), and covariates for which to adjust. Think exponents when combining possible choices.

Dr. Zeraatkar and colleagues are research methodologists, so, sadly, they are comfortable with the clunky name of this approach: specification curve analysis. Don’t be deterred. It means that they analyze the data in thousands of ways using computers. Each way is a specification. In the end, the specifications give rise to a curve of hazard ratios for red meat and mortality. Another name for this approach is multiverse analysis.

For their paper in the Journal of Clinical Epidemiology, aptly named “Grilling the Data,” they didn’t just conjure up the many analytic ways to study the red meat–mortality question. Instead, they used a published systematic review of 15 studies on unprocessed red meat and early mortality. The studies included in this review reported 70 unique ways to analyze the association. 
 

Is Red Meat Good or Bad?

Their first finding was that this analysis yielded widely disparate effect estimates, from 0.63 (reduced risk for early death) to 2.31 (a higher risk). The median hazard ratio was 1.14 with an interquartile range (IQR) of 1.02-1.23. One might conclude from this that eating red meat is associated with a slightly higher risk for early mortality. 

Their second step was to calculate how many ways (specifications) there were to analyze the data by totaling all possible combinations of choices in the 70 ways found in the systematic review. 

They calculated a total of 10 quadrillion possible unique analyses. A quadrillion is 1 with 15 zeros. Computing power cannot handle that amount of analyses yet. So, they generated 20 random unique combinations of covariates, which narrowed the number of analyses to about 1400. About 200 of these were excluded due to implausibly wide confidence intervals. 

Voilà. They now had about 1200 different ways to analyze a dataset; they chose an NHANES longitudinal cohort study from 2007-2014. They deemed each of the more than 1200 approaches plausible because they were derived from peer-reviewed papers written by experts in epidemiology. 
 

Specification Curve Analyses Results 

Each analysis (or specification) yielded a hazard ratio for red meat exposure and death.

• The median HR was 0.94 (IQR, 0.83-1.05) for the effect of red meat on all-cause mortality — ie, not significant.
• The range of hazard ratios was large. They went from 0.51 — a 49% reduced risk for early mortality — to 1.75: a 75% increase in early mortality.
• Among all analyses, 36% yielded hazard ratios above 1.0 and 64% less than 1.0.
• As for statistical significance, defined as P ≤.05, only 4% (or 48 specifications) met this threshold. Zeraatkar reminded me that this is what you’d expect if unprocessed red meat has no effect on longevity.
• Of the 48 analyses deemed statistically significant, 40 indicated that red meat consumption reduced early death and eight indicated that eating red meat led to higher mortality.
• Nearly half the analyses yielded unexciting point estimates, with hazard ratios between 0.90 and 1.10.

Paradigm Changing 

As a user of evidence, I find this a potentially paradigm-changing study. Observational studies far outnumber randomized trials. For many medical questions, observational data are all we have. 

Now think about every observational study published. The authors tell you — post hoc — which method they used to analyze the data. The key point is that it is one method. 

Dr. Zeraatkar and colleagues have shown that there are thousands of plausible ways to analyze the data, and this can lead to very different findings. In the specific question of red meat and mortality, their many analyses yielded a null result. 

Now imagine other cases where the researchers did many analyses of a dataset and chose to publish only the significant ones. Observational studies are rarely preregistered, so a reader cannot know how a result would vary depending on analytic choices. A specification curve analysis of a dataset provides a much broader picture. In the case of red meat, you see some significant results, but the vast majority hover around null. 

What about the difficulty in analyzing a dataset 1000 different ways? Dr. Zeraatkar told me that it is harder than just choosing one method, but it’s not impossible. 

The main barrier to adopting this multiverse approach to data, she noted, was not the extra work but the entrenched belief among researchers that there is a best way to analyze data. 

I hope you read this paper and think about it every time you read an observational study that finds a positive or negative association between two things. Ask: What if the researchers were as careful as Dr. Zeraatkar and colleagues and did multiple different analyses? Would the finding hold up to a series of plausible analytic choices? 

Nutritional epidemiology would benefit greatly from this approach. But so would any observational study of an exposure and outcome. I suspect that the number of “positive” associations would diminish. And that would not be a bad thing.

The median hazard ratio was 1.14 with an interquartile range (IQR) of 1.02-1.23. One might conclude from this that eating red meat is associated with a slightly higher risk for early mortality. 

Their second step was to calculate how many ways (specifications) there were to analyze the data by totaling all possible combinations of choices in the 70 ways found in the systematic review. 

They calculated a total of 10 quadrillion possible unique analyses. A quadrillion is 1 with 15 zeros. Computing power cannot handle that amount of analyses yet. So, they generated 20 random unique combinations of covariates, which narrowed the number of analyses to about 1400. About 200 of these were excluded due to implausibly wide confidence intervals. 

Voilà. They now had about 1200 different ways to analyze a dataset; they chose an NHANES longitudinal cohort study from 2007-2014. They deemed each of the more than 1200 approaches plausible because they were derived from peer-reviewed papers written by experts in epidemiology. 
 

Specification Curve Analyses Results 

Each analysis (or specification) yielded a hazard ratio for red meat exposure and death.

• The median HR was 0.94 (IQR, 0.83-1.05) for the effect of red meat on all-cause mortality — ie, not significant.
• The range of hazard ratios was large. They went from 0.51 — a 49% reduced risk for early mortality — to 1.75: a 75% increase in early mortality.
• Among all analyses, 36% yielded hazard ratios above 1.0 and 64% less than 1.0.
• As for statistical significance, defined as P ≤.05, only 4% (or 48 specifications) met this threshold. Zeraatkar reminded me that this is what you’d expect if unprocessed red meat has no effect on longevity.
• Of the 48 analyses deemed statistically significant, 40 indicated that red meat consumption reduced early death and eight indicated that eating red meat led to higher mortality.
• Nearly half the analyses yielded unexciting point estimates, with hazard ratios between 0.90 and 1.10.

Paradigm Changing 

As a user of evidence, I find this a potentially paradigm-changing study. Observational studies far outnumber randomized trials. For many medical questions, observational data are all we have. 

Now think about every observational study published. The authors tell you — post hoc — which method they used to analyze the data. The key point is that it is one method. 

Dr. Zeraatkar and colleagues have shown that there are thousands of plausible ways to analyze the data, and this can lead to very different findings. In the specific question of red meat and mortality, their many analyses yielded a null result. 

Now imagine other cases where the researchers did many analyses of a dataset and chose to publish only the significant ones. Observational studies are rarely preregistered, so a reader cannot know how a result would vary depending on analytic choices. A specification curve analysis of a dataset provides a much broader picture. In the case of red meat, you see some significant results, but the vast majority hover around null. 

What about the difficulty in analyzing a dataset 1000 different ways? Dr. Zeraatkar told me that it is harder than just choosing one method, but it’s not impossible. 

The main barrier to adopting this multiverse approach to data, she noted, was not the extra work but the entrenched belief among researchers that there is a best way to analyze data. 

I hope you read this paper and think about it every time you read an observational study that finds a positive or negative association between two things. Ask: What if the researchers were as careful as Dr. Zeraatkar and colleagues and did multiple different analyses? Would the finding hold up to a series of plausible analytic choices? 

Nutritional epidemiology would benefit greatly from this approach. But so would any observational study of an exposure and outcome. I suspect that the number of “positive” associations would diminish. And that would not be a bad thing.

BERLIN — To date, mRNA vaccines have had their largest global presence in combating the COVID-19 pandemic. Intensive research is underway on many other potential applications for this vaccine technology, which suggests a promising future. Martina Prelog, MD, a pediatric and adolescent medicine specialist at the University Hospital of Würzburg in Germany, reported on the principles, research status, and perspectives for these vaccines at the 25th Travel and Health Forum of the Center for Travel Medicine in Berlin.

To understand the future, the immunologist first examined the past. “The induction of cellular and humoral immune responses by externally injected mRNA was discovered in the 1990s,” she said.
 

Instability Challenge

Significant hurdles in mRNA vaccinations included the instability of mRNA and the immune system’s ability to identify foreign mRNA as a threat and destroy mRNA fragments. “The breakthrough toward vaccination came through Dr. Katalin Karikó, who, along with Dr. Drew Weissman, both of the University of Pennsylvania School of Medicine, discovered in 2005 that modifications of mRNA (replacing the nucleoside uridine with pseudouridine) enable better stability of mRNA, reduced immunogenicity, and higher translational capacity at the ribosomes,” said Dr. Prelog.

With this discovery, the two researchers paved the way for the development of mRNA vaccines against COVID-19 and other diseases. They were awarded the Nobel Prize in medicine for their discovery last year.
 

Improved Scalability

“Since 2009, mRNA vaccines have been studied as a treatment option for cancer,” said Dr. Prelog. “Since 2012, they have been studied for the influenza virus and respiratory syncytial virus [RSV].” Consequently, several mRNA vaccines are currently in development or in approval studies. “The mRNA technology offers the advantage of quickly and flexibly responding to new variants of pathogens and the ability to scale up production when there is high demand for a particular vaccine.”

Different forms and designations of mRNA vaccines are used, depending on the application and desired effect, said Dr. Prelog.

In nucleoside-modified mRNA vaccines, modifications in the mRNA sequence enable the mRNA to remain in the body longer and to induce protein synthesis more effectively.

Lipid nanoparticle (LNP)–encapsulated mRNA vaccines protect the coding mRNA sequences against degradation by the body’s enzymes and facilitate the uptake of mRNA into cells, where it then triggers the production of the desired protein. In addition, LNPs are involved in cell stimulation and support the self-adjuvant effect of mRNA vaccines, thus eliminating the need for adjuvants.

Self-amplifying mRNA vaccines include a special mRNA that replicates itself in the cell and contains a sequence for RNA replicase, in addition to the coding sequence for the protein. This composition enables increased production of the target protein without the need for a high amount of external mRNA administration. Such vaccines could trigger a longer and stronger immune response because the immune system has more time to interact with the protein.
 

Cancer Immunotherapy

Dr. Prelog also discussed personalized vaccines for cancer immunotherapy. Personalized mRNA vaccines are tailored to the patient’s genetic characteristics and antigens. They could be used in cancer immunotherapy to activate the immune system selectively against tumor cells.

Multivalent mRNA vaccines contain mRNA that codes for multiple antigens rather than just one protein to generate an immune response. These vaccines could be particularly useful in fighting pathogens with variable or changing surface structures or in eliciting protection against multiple pathogens simultaneously.

The technology of mRNA-encoded antibodies involves introducing mRNA into the cell, which creates light and heavy chains of antibodies. This step leads to the formation of antibodies targeted against toxins (eg, diphtheria and tetanus), animal venoms, infectious agents, or tumor cells.
 

Genetic Engineering

Dr. Prelog also reviewed genetic engineering techniques. In regenerative therapy or protein replacement therapy, skin fibroblasts or other cells are transfected with mRNA to enable conversion into induced pluripotent stem cells. This approach avoids the risk for DNA integration into the genome and associated mutation risks.

Another approach is making post-transcriptional modifications through RNA interference. For example, RNA structures can be used to inhibit the translation of disease-causing proteins. This technique is currently being tested against HIV and tumors such as melanoma.

In addition, mRNA technologies can be combined with CRISPR/Cas9 technology (“gene scissors”) to influence the creation of gene products even more precisely. The advantage of this technique is that mRNA is only transiently expressed, thus preventing unwanted side effects. Furthermore, mRNA is translated directly in the cytoplasm, leading to a faster initiation of gene editing.

Of the numerous ongoing clinical mRNA vaccine studies, around 70% focus on infections, about 12% on cancer, and the rest on autoimmune diseases and neurodegenerative disorders, said Dr. Prelog.
 

Research in Infections

Research in the fields of infectious diseases and oncology is the most advanced: mRNA vaccines against influenza and RSV are already in advanced clinical trials, Dr. Prelog told this news organization.

“Conventional influenza vaccines contain immunogenic surface molecules against hemagglutinin and neuraminidase in various combinations of influenza strains A and B and are produced in egg or cell cultures,” she said. “This is a time-consuming manufacturing process that takes months and, particularly with the egg-based process, bears the risk of changing the vaccine strain.”

“Additionally, influenza viruses undergo antigenic shift and drift through recombination, thus requiring annual adjustments to the vaccines. Thus, these influenza vaccines often lose accuracy in targeting circulating seasonal influenza strains.”

Several mRNA vaccines being tested contain not only coding sequences against hemagglutinin and neuraminidase but also for structural proteins of influenza viruses. “These are more conserved and mutate less easily, meaning they could serve as the basis for universal pandemic influenza vaccines,” said Dr. Prelog.

An advantage of mRNA vaccines, she added, is the strong cellular immune response that they elicit. This response is intended to provide additional protection alongside specific antibodies. An mRNA vaccine with coding sequences for the pre-fusion protein of RSV is in phase 3 trials for approval for vaccination in patients aged 60 years and older. It shows high effectiveness even in older patients and those with comorbidities.
 

Elaborate Purification Process

Bacterial origin plasmid DNA is used to produce mRNA vaccines. The mRNA vaccines for COVID-19 raised concerns that production-related DNA residues could pose a safety risk and cause autoimmune diseases.

These vaccines “typically undergo a very elaborate purification process,” said Dr. Prelog. “This involves enzymatic digestion with DNase to fragment and deplete plasmid DNA, followed by purification using chromatography columns, so that no safety-relevant DNA fragments should remain afterward.”

Thus, the Paul-Ehrlich-Institut also pointed out the very small, fragmented plasmid DNA residues of bacterial origin in mRNA COVID-19 vaccines pose no risk, unlike residual DNA from animal cell culture might pose in other vaccines.
 

Prevention and Therapy

In addition to the numerous advantages of mRNA vaccines (such as rapid adaptability to new or mutated pathogens, scalability, rapid production capability, self-adjuvant effect, strong induction of cellular immune responses, and safety), there are also challenges in RNA technology as a preventive and therapeutic measure, according to Dr. Prelog.

“Stability and storability, as well as the costs of new vaccine developments, play a role, as do the long-term effects regarding the persistence of antibody and cellular responses,” she said. The COVID-19 mRNA vaccines, for example, showed a well-maintained cellular immune response despite a tendency toward a rapid decline in humoral immune response.

“The experience with COVID-19 mRNA vaccines and the new vaccine developments based on mRNA technology give hope for an efficient and safe preventive and therapeutic use, particularly in the fields of infectious diseases and oncology,” Dr. Prelog concluded.

Physicians are leaving healthcare in droves, “not because they don’t want to practice ... but because the system is making it more and more difficult for them to care for their patients,” Bruce Scott, MD, president-elect of the American Medical Association (AMA), said at a press conference May 9 at the National Rural Health Association’s Annual Conference in New Orleans. 

He said that shrinking reimbursement rates and excessive administrative tasks are pushing doctors out of the workforce, exacerbating physician shortages in rural locations where 46 million Americans live. 

Rural areas have about one tenth of the specialists that urban areas do, and 65% of rural communities do not have enough primary care doctors, according to federal data. A recent Centers for Disease Control and Prevention report found that people living in rural areas are more likely to die early from preventable causes than their urban counterparts, said Dr. Scott. 

He said the AMA wants Congress to pass legislation to incentivize more physicians to work in rural areas and expand the number of rural and primary care residency spots. Historically, 80% of residents practice within 80 miles of where they complete residency, he said. 

Dr. Scott also hopes Congress will revise the J-1 visa rules to allow qualified international medical graduates to continue to practice in the United States. He’d like to see the pandemic telehealth flexibilities made permanent because these loosened guidelines greatly improved care access for rural areas in recent years. 

Lower Pay Affects Care in Rural, Urban Areas

Decreased reimbursements also have hit rural and urban doctors in independent practice particularly hard, Dr. Scott said. When adjusted for inflation, the current Medicare payment rate for physicians has dropped 29% since 2001, he said. Now that commercial payers tie their reimbursement models to the Medicare rate, physicians are experiencing “severe” financial stress amid rising practice costs and student loan debt. 

He shared anecdotes about how these issues have affected his private otolaryngology practice in Louisville, Kentucky, a state where more than 2 million people live in federally designated primary care professional shortage areas. 

“A major insurance company that controls over 60% of the private payer market in rural Kentucky [recently] offered us ... surgical rates less than they paid us 6 years ago,” he said. 

Dr. Scott said physicians must make difficult choices. “Do we not invest in the latest physical equipment? Do we reduce our number of employees? Do we perhaps stop accepting new Medicare patients?”

He noted that physicians now spend twice as much time on prior authorizations and other administrative tasks as they do on direct patient care. According to a 2022 AMA survey, 33% of physicians reported that the cumbersome prior authorization process led to a serious adverse event for a patient. Eighty percent reported it caused their patient to forgo treatment altogether.

Dr. Scott, who will be sworn in as AMA president in June, said he experiences the frustration daily. 

“I have to get on the phone and justify to an insurance person who rarely has gone to medical school, has never seen the patient, and heck, in my case, sometimes they can’t even say otolaryngology, much less tell me what the appropriate care is for my patient,” he said.

When asked about the impact of private equity in healthcare, Dr. Scott said there is room for all different modes of practice, but private equity could bring a unique benefit. 

“They have deeper pockets to potentially invest in telehealth technology, AI, and better computer systems,” he said. 

But, he said, some private equity-owned systems have abandoned rural areas, and in other regions they “push the physicians to move faster, see more patients, and do the things that are profit-driven.

“The key is to continue to provide ... quality medical care that is determined by an individual physician in consultation with the patient.”

He said the AMA wants Congress to pass legislation to incentivize more physicians to work in rural areas and expand the number of rural and primary care residency spots. Historically, 80% of residents practice within 80 miles of where they complete residency, he said. 

Dr. Scott also hopes Congress will revise the J-1 visa rules to allow qualified international medical graduates to continue to practice in the United States. He’d like to see the pandemic telehealth flexibilities made permanent because these loosened guidelines greatly improved care access for rural areas in recent years. 

Lower Pay Affects Care in Rural, Urban Areas

Decreased reimbursements also have hit rural and urban doctors in independent practice particularly hard, Dr. Scott said. When adjusted for inflation, the current Medicare payment rate for physicians has dropped 29% since 2001, he said. Now that commercial payers tie their reimbursement models to the Medicare rate, physicians are experiencing “severe” financial stress amid rising practice costs and student loan debt. 

He shared anecdotes about how these issues have affected his private otolaryngology practice in Louisville, Kentucky, a state where more than 2 million people live in federally designated primary care professional shortage areas. 

“A major insurance company that controls over 60% of the private payer market in rural Kentucky [recently] offered us ... surgical rates less than they paid us 6 years ago,” he said. 

Dr. Scott said physicians must make difficult choices. “Do we not invest in the latest physical equipment? Do we reduce our number of employees? Do we perhaps stop accepting new Medicare patients?”

He noted that physicians now spend twice as much time on prior authorizations and other administrative tasks as they do on direct patient care. According to a 2022 AMA survey, 33% of physicians reported that the cumbersome prior authorization process led to a serious adverse event for a patient. Eighty percent reported it caused their patient to forgo treatment altogether.

Dr. Scott, who will be sworn in as AMA president in June, said he experiences the frustration daily. 

“I have to get on the phone and justify to an insurance person who rarely has gone to medical school, has never seen the patient, and heck, in my case, sometimes they can’t even say otolaryngology, much less tell me what the appropriate care is for my patient,” he said.

When asked about the impact of private equity in healthcare, Dr. Scott said there is room for all different modes of practice, but private equity could bring a unique benefit. 

“They have deeper pockets to potentially invest in telehealth technology, AI, and better computer systems,” he said. 

But, he said, some private equity-owned systems have abandoned rural areas, and in other regions they “push the physicians to move faster, see more patients, and do the things that are profit-driven.

“The key is to continue to provide ... quality medical care that is determined by an individual physician in consultation with the patient.”

Cisplatin is a preferred treatment for a wide range of cancers, including breast, head and neck, lung, ovary, and more. However, its side effects — particularly nephrotoxicity — can be severe. Kidney injury on cisplatin is associated with higher mortality and can jeopardize a patient’s eligibility for other therapies.

Now, in a large study using data from six US cancer centers, researchers have developed a risk algorithm to predict acute kidney injury (AKI) after cisplatin administration.

A risk prediction calculator based on the algorithm is available online for patients and providers to determine an individual patient›s risk for kidney injury from cisplatin using readily available clinical data.

Other risk scores and risk prediction models have been developed to help clinicians assess in advance whether a patient might develop AKI after receiving cisplatin, so that more careful monitoring, dose adjustments, or an alternative treatment, if available, might be considered.

However, previous models were limited by factors such as small sample sizes, lack of external validation, older data, and liberal definitions of AKI, said Shruti Gupta, MD, MPH, director of onco-nephrology at Brigham and Women’s Hospital (BWH) and Dana-Farber Cancer Institute, and David E. Leaf, MD, MMSc, director of clinical and translational research in AKI, Division of Renal Medicine, BWH, Boston.

Dr. Gupta and Dr. Leaf believe their risk score for predicting severe AKI after intravenous (IV) cisplatin, published online in The BMJ, is “more accurate and generalizable than prior models for several reasons,” they told this news organization in a joint email.

“First, we externally validated our findings across cancer centers other than the one where it was developed,” they said. “Second, we focused on moderate to severe kidney injury, the most clinically relevant form of kidney damage, whereas prior models examined more mild forms of kidney injury. Third, we collected data on nearly 25,000 patients receiving their first dose of IV cisplatin, which is larger than all previous studies combined.”
 

‘Herculean Effort’

“We conceived of this study back in 2018, contacted collaborators at each participating cancer center, and had numerous meetings to try to gather granular data on patients treated with their first dose of intravenous (IV) cisplatin,” Dr. Gupta and Dr. Leaf explained. They also incorporated patient feedback from focus groups and surveys.

“This was truly a Herculean effort that involved physicians, programmers, research coordinators, and patients,” they said.

The multicenter study included 24,717 patients — 11,766 in the derivation cohort and 12,951 in the validation cohort. Overall, the median age was about 60 years, about 58% were men, and about 78% were White.

The primary outcome was cisplatin-induced AKI (CP-AKI), defined as a twofold or greater increase in serum creatinine or kidney replacement therapy within 14 days of a first dose of IV cisplatin.

The researchers found that the incidence of CP-AKI was 5.2% in the derivation cohort and 3.3% in the validation cohort. Their simple risk score consisting of nine covariates — age, hypertension, type 2 diabetes, hemoglobin level, white blood cell count, platelet count, serum albumin level, serum magnesium level, and cisplatin dose — predicted a higher risk for CP-AKI in both cohorts.

Notably, adding serum creatinine to the model did not change the area under the curve, and therefore, serum creatinine, though also an independent risk factor for CP-AKI, was not included in the score.

Patients in the highest risk category had 24-fold higher odds of CP-AKI in the derivation cohort and close to 18-fold higher odds in the validation cohort than those in the lowest risk category.

The primary model had a C statistic of 0.75 (95% CI, 0.73-0.76) and showed better discrimination for CP-AKI than previously published models, for which the C statistics ranged from 0.60 to 0.68. The first author of a paper on an earlier model, Shveta Motwani, MD, MMSc, of BWH and Dana-Farber Cancer Institute in Boston, is also a coauthor of the new study.

Greater severity of CP-AKI was associated with shorter 90-day survival (adjusted hazard ratio, 4.63; 95% CI, 3.56-6.02) for stage III CP-AKI vs no CP-AKI.
 

‘Definitive Work’

Joel M. Topf, MD, a nephrologist with expertise in chronic kidney disease in Detroit, who wasn’t involved in the development of the risk score, called the study “a definitive work on an important concept in oncology and nephrology.”

“While this is not the first attempt to devise a risk score, it is by far the biggest,” he told this news organization. Furthermore, the authors “used a diverse population, recruiting patients with a variety of cancers (previous attempts had often used a homogenous diagnosis, putting into question how generalizable the results were) from six different cancer centers.”

In addition, he said, “The authors did not restrict patients with chronic kidney disease or other significant comorbidities and used the geographic diversity to produce a cohort that has an age, gender, racial, and ethnic distribution, which is more representative of the US than previous, single-center attempts to risk score patients.”

An earlier model used the Kidney Disease: Improving Global Outcomes (KDIGO) consensus definition of AKI of an increase in serum creatinine of 0.3 mg/dL, he noted. “While a sensitive definition of AKI, it captures mild, hemodynamic increases in creatinine of questionable significance,” he said.

By contrast, the new score uses KDIGO stage II and above to define AKI. “This is a better choice, as we do not want to dissuade patients and doctors from choosing chemotherapy due to a fear of insignificant kidney damage,” he said.

All that said, Dr. Topf noted that neither the current score nor the earlier model included serum creatinine. “This is curious to me and may represent the small number of patients with representative elevated creatinine in the derivation cohort (only 1.3% with an estimated glomerular filtration rate [eGFR] < 45).”

“Since the cohort is made up of people who received cis-platinum, the low prevalence of eGFRs < 45 may be due to physicians steering away from cis-platinum in this group,” he suggested. “It would be unfortunate if this risk score gave an unintentional ‘green light’ to these patients, exposing them to predictable harm.”
 

‘Certainly Useful’

Anushree Shirali, MD, an associate professor in the Section of Nephrology and consulting physician, Yale Onco-Nephrology, Yale School of Medicine, in New Haven, Connecticut, said that having a prediction score for which patients are more likely to develop AKI after a single dose of cisplatin would be helpful for oncologists, as well as nephrologists.

As a nephrologist, Dr. Shirali mostly sees patients who already have AKI, she told this news organization. But there are circumstances in which the tool could still be helpful.

“Let’s say someone has abnormal kidney function at baseline — ie, creatinine is higher than the normal range — and they were on dialysis 5 years ago for something else, and now, they have cancer and may be given cisplatin. They worry about their chances of getting AKI and needing dialysis again,” she said. “That’s just one scenario in which I might be asked to answer that question and the tool would certainly be useful.”

Other scenarios could include someone who has just one kidney because they donated a kidney for transplant years ago, and now, they have a malignancy and wonder what their actual risk is of getting kidney issues on cisplatin.

Oncologists could use the tool to determine whether a patient should be treated with cisplatin, or if they’re at high risk, whether an alternative that’s not nephrotoxic might be used. By contrast, “if somebody’s low risk and an oncologist thinks cisplatin is the best agent they have, then they might want to go ahead and use it,” Dr. Shirali said.

Future research could take into consideration that CP-AKI is dose dependent, she suggested, because a prediction score that included the number of cisplatin doses could be even more helpful to determine risk. And, even though the derivation and validation cohorts for the new tool are representative of the US population, additional research should also include more racial/ethnic diversity, she said.

Dr. Gupta and Dr. Leaf hope their tool “will be utilized immediately by patients and providers to help predict an individual’s risk of cisplatin-associated kidney damage. It is easy to use, available for free online, and incorporates readily available clinical variables.”

If a patient is at high risk, the clinical team can consider preventive measures such as administering more IV fluids before receiving cisplatin or monitoring kidney function more closely afterward, they suggested.

Dr. Gupta reported research support from the National Institutes of Health (NIH) and the National Institute of Diabetes and Digestive and Kidney Diseases. She also reported research funding from BTG International, GE HealthCare, and AstraZeneca outside the submitted work. She is a member of GlaxoSmithKline’s Global Anemia Council, a consultant for Secretome and Proletariat Therapeutics, and founder and president emeritus of the American Society of Onconephrology (unpaid). Dr. Leaf is supported by NIH grants, reported research support from BioPorto, BTG International, and Metro International Biotech, and has served as a consultant. Dr. Topf reported an ownership stake in a few DaVita-run dialysis clinics. He also runs a vascular access center and has participated in advisory boards with Cara Therapeutics, Vifor, Astra Zeneca, Bayer, Renibus Therapeutics, Travere Therapeutics, and GlaxoSmithKline. He is president of NephJC, a nonprofit educational organization with no industry support. Dr. Shirali declared no competing interests.

Like it or not, artificial intelligence (AI) is coming to medicine. For many physicians — maybe you — it’s already here.

More than a third of physicians use AI in their practice. And the vast majority of healthcare companies — 94%, according to Morgan Stanley — use some kind of AI machine learning.

“It’s incumbent on physicians, as well as physicians in training, to become familiar with at least the basics [of AI],” said internist Matthew DeCamp, MD, PhD, an associate professor in the Center for Bioethics and Humanities at the University of Colorado Anschutz Medical Campus, Aurora, Colorado.

Understanding AI can help you leverage it safely and effectively — plus “make better-informed decisions about whether or not to use it in [your] practice,” Dr. DeCamp said.

“Frankly, the people who are deciding whether to implement algorithms in our day-to-day lives are oftentimes not physicians,” noted Ravi B. Parikh, MD, an assistant professor at the University of Pennsylvania and director of augmented and artificial intelligence at the Penn Center for Cancer Care Innovation, Philadelphia. Yet, physicians are most qualified to assess an AI tool’s usefulness in clinical practice.

That brings us to the best starting place for your AI education: Your own institution. Find out what AI tools your organization is implementing — and how you can influence them.

“Getting involved with our hospital data governance is the best way not only to learn practically what these AI tools do but also to influence the development process in positive ways,” Dr. Parikh said.

From there, consider the following resources to enhance your AI knowledge.
 

Get a Lay of the Land: Free Primers

Many clinical societies and interest groups have put out AI primers, an easy way to get a broad overview of the technology. The following were recommended or developed by the experts we spoke to, and all are free:

• The American Medical Association’s (AMA’s) framework for advancing healthcare AI lays out actionable guidance. Ask three key questions, the AMA recommends: Does it work? Does it work for my patients? Does it improve health outcomes?
• The Coalition for Health AI’s Blueprint for Trustworthy AI Implementation Guidance and Assurance for Healthcare provides a high-level summary of how to evaluate AI in healthcare, plus steps for implementing it. AI systems should be useful, safe, accountable, explainable, fair, and secure, the report asserted.
• The National Academy of Medicine’s draft code of conduct for AI in healthcare proposes core principles and commitments. These “reflect simple guideposts to guide and gauge behavior in a complex system and provide a starting point for real-time decision-making,” the report said.
• Health AI Partnership — a collaboration of Duke Health and Microsoft — outlines eight key decision points to consider at any stage of AI implementation, whether you’re still planning how to use it or you’ve started but want to improve it. The site also provides a breakdown of standards by regulatory agencies, organizations, and oversight bodies — so you can make sure your practices align with their guidance.

Like it or not, artificial intelligence (AI) is coming to medicine. For many physicians — maybe you — it’s already here.

More than a third of physicians use AI in their practice. And the vast majority of healthcare companies — 94%, according to Morgan Stanley — use some kind of AI machine learning.

“It’s incumbent on physicians, as well as physicians in training, to become familiar with at least the basics [of AI],” said internist Matthew DeCamp, MD, PhD, an associate professor in the Center for Bioethics and Humanities at the University of Colorado Anschutz Medical Campus, Aurora, Colorado.

Understanding AI can help you leverage it safely and effectively — plus “make better-informed decisions about whether or not to use it in [your] practice,” Dr. DeCamp said.

“Frankly, the people who are deciding whether to implement algorithms in our day-to-day lives are oftentimes not physicians,” noted Ravi B. Parikh, MD, an assistant professor at the University of Pennsylvania and director of augmented and artificial intelligence at the Penn Center for Cancer Care Innovation, Philadelphia. Yet, physicians are most qualified to assess an AI tool’s usefulness in clinical practice.

That brings us to the best starting place for your AI education: Your own institution. Find out what AI tools your organization is implementing — and how you can influence them.

“Getting involved with our hospital data governance is the best way not only to learn practically what these AI tools do but also to influence the development process in positive ways,” Dr. Parikh said.

From there, consider the following resources to enhance your AI knowledge.
 

Get a Lay of the Land: Free Primers

Many clinical societies and interest groups have put out AI primers, an easy way to get a broad overview of the technology. The following were recommended or developed by the experts we spoke to, and all are free:

• The American Medical Association’s (AMA’s) framework for advancing healthcare AI lays out actionable guidance. Ask three key questions, the AMA recommends: Does it work? Does it work for my patients? Does it improve health outcomes?
• The Coalition for Health AI’s Blueprint for Trustworthy AI Implementation Guidance and Assurance for Healthcare provides a high-level summary of how to evaluate AI in healthcare, plus steps for implementing it. AI systems should be useful, safe, accountable, explainable, fair, and secure, the report asserted.
• The National Academy of Medicine’s draft code of conduct for AI in healthcare proposes core principles and commitments. These “reflect simple guideposts to guide and gauge behavior in a complex system and provide a starting point for real-time decision-making,” the report said.
• Health AI Partnership — a collaboration of Duke Health and Microsoft — outlines eight key decision points to consider at any stage of AI implementation, whether you’re still planning how to use it or you’ve started but want to improve it. The site also provides a breakdown of standards by regulatory agencies, organizations, and oversight bodies — so you can make sure your practices align with their guidance.

In the first randomized controlled trial of prednisone for postvasectomy reversals, fertility researchers found that a high dose of the steroid reduced the rate of subsequent pregnancy.

“This is the first time it’s been shown that high doses [of prednisone] can make someone infertile,” said Landon Trost, MD, director of the Male Fertility and Peyronie’s Clinic in Orem, Utah, and a faculty member at Mayo Clinic, in Rochester, Minnesota, who presented the study (Abstract MP42-19) on May 4 at the 2024 annual meeting of the American Urological Association (AUA) in San Antonio, Texas. 

Dr. Trost called the findings “a real shock. I almost didn’t believe the data when I saw it. It opens up a whole new set of areas for research and exploration.”

Dr. Trost’s clinic performs 1200 reversals per year out of the estimated 20,000 performed annually in the United States, he said. He said his practice has stopped using high-dose prednisone as a result of the study, which he performed at his own expense to examine the varying protocols for vasectomy reversal.

William Berg, MD, director of the Stony Brook Urology Men’s Health Program, in Stony Brook, New York, said that the expected patency rate for modern postvasectomy reversals, if performed properly, can be as high as 98%. However, in some men, patency occurs initially, but the accumulation of scar tissue at the site of reversal causes sperm counts in ejaculate to drop to zero.

Since the 1970s, urologists — with limited research to back — the practice  prescribed prednisone to patients with the goal of preventing scarring and blockages associated with vasectomy reversals. Dr. Berg called this practice “unsubstantiated” and noted that Dr. Trost’s study is the first prospective randomized controlled trial of this approach.

The study enrolled 75 men, with a mean age of roughly 38 years. The mean time since vasectomy was 6.6 years.

The low-dose arm (25 patients) received 5 mg of prednisone per week alternating with no treatment per week over 6 months. The high-dose arm (n = 14) received 20 mg of prednisone, tapered to 10 mg, 5 mg, and then off over 1 month, followed by every other month for 6 months. A prednisone-as-needed group (n = 11) received a tapered course of prednisone on the basis of whether they had decreasing or zero sperm counts. They received 20 mg for 5 days, 10 mg for 5 days, and 5 mg for 20 days.

A control arm (n = 25) received no prednisone.

Urologists typically use patency rates to measure success of vasectomy reversals. The patency rates at 12 months in Dr. Trost’s study were 100% in the control participants, prednisone-as-needed, and low-dose groups and 92% (13/14) in the high-dose group. 

Dr. Trost said that the story was told in the pregnancy rates. At the 1-year mark, pregnancy rates were 67% in the low-risk group and 65% in the control group but 38% and 17% in the prednisone-as-needed and high-dose group, respectively (P = .02).

The mean maximum sperm concentration was 40 million per mL, ranging from 29.7 million per mL for men in the control group to 54.3 million per mL in the low-dose group.

Dr. Trost said that he immediately stopped using high doses of prednisone in his practice and predicted that other clinics would follow suit. 

Dr. Berg said the drop in pregnancies with higher doses of prednisone is a first-time finding and suggests that a high dose may “be detrimental to sperm function in some way. I don’t think this ever has been described before.”

Dr. Trost financed the study himself. Dr. Berg reported no conflicts.

A plastic surgeon broke federal law when he restricted patients from posting negative reviews by requiring them to sign nondisclosure agreements before they received care, a district judge has ruled.

Seattle-based surgeon Javad Sajan, MD, ran afoul of the Consumer Review Fairness Act (CRFA) by requiring more than 10,000 patients to sign the agreements, according to a recent decision by US District Judge Ricardo S. Martinez. The law protects consumers’ rights to post truthful reviews about businesses. 

Judge Martinez wrote that the terms of Dr. Sajan’s nondisclosure agreements “clearly include language prohibiting or restricting patients from posting negative reviews,” in violation of CRFA. Penalties for the offense will be determined at a September trial. 

This news organization contacted Dr. Sajan’s office and his attorney for comment but did not get a response. 

The decision is the latest development in an ongoing legal dispute between Dr. Sajan and the State of Washington over whether the surgeon’s efforts to limit negative online reviews were illegal. 

Beginning in 2017, Dr. Sajan and his practice, Allure Esthetic, introduced agreements that “forced” patients to contact the business directly if they had concerns rather than post a negative review, according to a 2022 lawsuit against Dr. Sajan filed by Washington Attorney General Robert Ferguson. 

“Online reviews are often the first stop when consumers are determining who to trust,” Mr. Ferguson said in a statement. “That’s especially critical when those services deal with a patient’s health and safety. We will take action against those who illegally stop Washingtonians from sharing reviews with the public.”

If patients posted negative reviews, the clinic, in some cases, threatened litigation, according to the complaint. In other cases, patients were allegedly offered money and free services in exchange for taking the reviews down. Patients who accepted cash or services were required to sign a second agreement forbidding them from posting future negative reviews and imposing a $250,000 penalty for failure to comply, according to court documents. 

In court documents, Dr. Sajan’s attorneys argued the agreements did not violate CRFA because patients had the opportunity to modify the language or decline signing them, which hundreds did. The CRFA requires Mr. Ferguson to prove that consumers lacked a meaningful opportunity to negotiate the terms, attorneys for Dr. Sajan argued in court records. 

But Judge Martinez wrote that the patients who declined to sign the agreements or changed the terms represented only a “tiny fraction” of the affected patients.

The agreement language restricts patients from speaking out by forcing dissatisfied patients to work with Allure until a resolution is reached, Judge Martinez noted in his decision. “At the very least, this would delay patients from posting such reviews and force patients to interact in some way with Allure, and it certainly appears to prohibit posting reviews until Allure agrees to some kind of favorable resolution.”
 

Surgeon Posted Fake Positive Reviews to Counteract Bad Reviews, AG Says

Employee accounts in court documents describe a physician fixated on reviews who went to great lengths to ensure positive reviews about his work outweighed the negative. 

Former employees said they were instructed to track down patients who left negative reviews and either “threaten” them to take the posts down or offer them “money” or other things, according to Mr. Ferguson’s lawsuit. If patients could not be identified, the practice would file a defamation lawsuit against the anonymous person who posted the review and use litigation to subpoena the website for the reviewer’s IP address in order to identify them, according to court documents. 

Employees testified they had regular meetings to review current negative reviews and discuss what steps they were taking to get them removed. At team meetings, in-house counsel would regularly present an Excel spreadsheet with updates on progress in getting patients to remove negative reviews, according to court documents. 

In addition to restricting negative reviews, Mr. Ferguson accuses Dr. Sajan of posting fake positive reviews and “buying” thousands of fake followers on social media. 

At Dr. Sajan’s direction, employees created Gmail accounts using stock photos for their profile pictures and used the accounts to post fake reviews of Allure Esthetic and Dr. Sajan, according to the complaint. The practice also used members of an online forum called BlackHatWorld.com to create fake email accounts and to post fake reviews, the attorney general alleges. Many of the fake positive reviews, including the fake Google reviews, still appear on online review sites today, the attorney general contends. 

Dr. Sajan and his practice also allegedly manipulated social media to appear more popular. Mr. Ferguson claims that Dr. Sajan instructed his former web designer to purchase 60,000 followers through a vendor on BlackHatWorld.com. Most of Dr. Sajan’s current Instagram followers are not real, according to Mr. Ferguson. 

The practice also used a social media bot tool to buy thousands of fake likes on Instagram, YouTube, and other social media, according to court documents. 

In addition, Dr. Sajan and his practice are accused of significantly altering “before and after” photos of patients and using fake email accounts to allow the clinic to take skincare rebates intended for patients.

All of these practices violated HIPAA, the state Consumer Protection Act (CPA) and the federal CRFA, according to Mr. Ferguson. 
 

Surgeon Claims Competitor Behind Allegations 

Attorneys for Dr. Sajan argue a competitor is behind the accusations and that other regulatory entities determined the practice did nothing wrong. 

The competitor, a Seattle-based plastic surgeon, filed numerous complaints about Dr. Sajan to the Washington Medical Commission (WMC), according to court documents. The medical commission reviewed the third agreement and closed its investigation, finding that if the allegations were true, “no violation of law occurred,” court records show. 

“Defendants relied upon this closing code from the WMC that the (non-disclosure) forms were lawful,” Dr. Sajan’s attorneys wrote in court documents.

The US Department of Health & Human Services Office for Civil Rights (OCR) also reviewed and audited Dr. Sajan’s use of the agreements, his attorneys noted. In a notice from OCR included in court exhibits, the agency wrote that all matters at issue have now been resolved through the practice’s voluntary compliance actions and that it was closing its investigation. 

Attorneys for Dr. Sajan accuse Mr. Ferguson and state investigators of withholding the full extent of the competitor’s involvement in their investigation and failing to identify the competitor in written discovery or any of its initial disclosures. Dr. Sajan and his team discovered that the competitor was a source of key information through public records requests, according to court documents. 

The remaining claims against Dr. Sajan will be addressed at trial, set for September 9, 2024.

Attorneys for Dr. Sajan accuse Mr. Ferguson and state investigators of withholding the full extent of the competitor’s involvement in their investigation and failing to identify the competitor in written discovery or any of its initial disclosures. Dr. Sajan and his team discovered that the competitor was a source of key information through public records requests, according to court documents. 

The remaining claims against Dr. Sajan will be addressed at trial, set for September 9, 2024.

A plastic surgeon broke federal law when he restricted patients from posting negative reviews by requiring them to sign nondisclosure agreements before they received care, a district judge has ruled.

Seattle-based surgeon Javad Sajan, MD, ran afoul of the Consumer Review Fairness Act (CRFA) by requiring more than 10,000 patients to sign the agreements, according to a recent decision by US District Judge Ricardo S. Martinez. The law protects consumers’ rights to post truthful reviews about businesses. 

Judge Martinez wrote that the terms of Dr. Sajan’s nondisclosure agreements “clearly include language prohibiting or restricting patients from posting negative reviews,” in violation of CRFA. Penalties for the offense will be determined at a September trial. 

This news organization contacted Dr. Sajan’s office and his attorney for comment but did not get a response. 

The decision is the latest development in an ongoing legal dispute between Dr. Sajan and the State of Washington over whether the surgeon’s efforts to limit negative online reviews were illegal. 

Beginning in 2017, Dr. Sajan and his practice, Allure Esthetic, introduced agreements that “forced” patients to contact the business directly if they had concerns rather than post a negative review, according to a 2022 lawsuit against Dr. Sajan filed by Washington Attorney General Robert Ferguson. 

“Online reviews are often the first stop when consumers are determining who to trust,” Mr. Ferguson said in a statement. “That’s especially critical when those services deal with a patient’s health and safety. We will take action against those who illegally stop Washingtonians from sharing reviews with the public.”

If patients posted negative reviews, the clinic, in some cases, threatened litigation, according to the complaint. In other cases, patients were allegedly offered money and free services in exchange for taking the reviews down. Patients who accepted cash or services were required to sign a second agreement forbidding them from posting future negative reviews and imposing a $250,000 penalty for failure to comply, according to court documents. 

In court documents, Dr. Sajan’s attorneys argued the agreements did not violate CRFA because patients had the opportunity to modify the language or decline signing them, which hundreds did. The CRFA requires Mr. Ferguson to prove that consumers lacked a meaningful opportunity to negotiate the terms, attorneys for Dr. Sajan argued in court records. 

But Judge Martinez wrote that the patients who declined to sign the agreements or changed the terms represented only a “tiny fraction” of the affected patients.

The agreement language restricts patients from speaking out by forcing dissatisfied patients to work with Allure until a resolution is reached, Judge Martinez noted in his decision. “At the very least, this would delay patients from posting such reviews and force patients to interact in some way with Allure, and it certainly appears to prohibit posting reviews until Allure agrees to some kind of favorable resolution.”
 

Surgeon Posted Fake Positive Reviews to Counteract Bad Reviews, AG Says

Employee accounts in court documents describe a physician fixated on reviews who went to great lengths to ensure positive reviews about his work outweighed the negative. 

Former employees said they were instructed to track down patients who left negative reviews and either “threaten” them to take the posts down or offer them “money” or other things, according to Mr. Ferguson’s lawsuit. If patients could not be identified, the practice would file a defamation lawsuit against the anonymous person who posted the review and use litigation to subpoena the website for the reviewer’s IP address in order to identify them, according to court documents. 

Employees testified they had regular meetings to review current negative reviews and discuss what steps they were taking to get them removed. At team meetings, in-house counsel would regularly present an Excel spreadsheet with updates on progress in getting patients to remove negative reviews, according to court documents. 

In addition to restricting negative reviews, Mr. Ferguson accuses Dr. Sajan of posting fake positive reviews and “buying” thousands of fake followers on social media. 

At Dr. Sajan’s direction, employees created Gmail accounts using stock photos for their profile pictures and used the accounts to post fake reviews of Allure Esthetic and Dr. Sajan, according to the complaint. The practice also used members of an online forum called BlackHatWorld.com to create fake email accounts and to post fake reviews, the attorney general alleges. Many of the fake positive reviews, including the fake Google reviews, still appear on online review sites today, the attorney general contends. 

Dr. Sajan and his practice also allegedly manipulated social media to appear more popular. Mr. Ferguson claims that Dr. Sajan instructed his former web designer to purchase 60,000 followers through a vendor on BlackHatWorld.com. Most of Dr. Sajan’s current Instagram followers are not real, according to Mr. Ferguson. 

The practice also used a social media bot tool to buy thousands of fake likes on Instagram, YouTube, and other social media, according to court documents. 

In addition, Dr. Sajan and his practice are accused of significantly altering “before and after” photos of patients and using fake email accounts to allow the clinic to take skincare rebates intended for patients.

All of these practices violated HIPAA, the state Consumer Protection Act (CPA) and the federal CRFA, according to Mr. Ferguson. 
 

Surgeon Claims Competitor Behind Allegations 

Attorneys for Dr. Sajan argue a competitor is behind the accusations and that other regulatory entities determined the practice did nothing wrong. 

The competitor, a Seattle-based plastic surgeon, filed numerous complaints about Dr. Sajan to the Washington Medical Commission (WMC), according to court documents. The medical commission reviewed the third agreement and closed its investigation, finding that if the allegations were true, “no violation of law occurred,” court records show. 

“Defendants relied upon this closing code from the WMC that the (non-disclosure) forms were lawful,” Dr. Sajan’s attorneys wrote in court documents.

The US Department of Health & Human Services Office for Civil Rights (OCR) also reviewed and audited Dr. Sajan’s use of the agreements, his attorneys noted. In a notice from OCR included in court exhibits, the agency wrote that all matters at issue have now been resolved through the practice’s voluntary compliance actions and that it was closing its investigation. 

Attorneys for Dr. Sajan accuse Mr. Ferguson and state investigators of withholding the full extent of the competitor’s involvement in their investigation and failing to identify the competitor in written discovery or any of its initial disclosures. Dr. Sajan and his team discovered that the competitor was a source of key information through public records requests, according to court documents. 

The remaining claims against Dr. Sajan will be addressed at trial, set for September 9, 2024.

CHICAGO — The diabetes/weight loss drug semaglutide is associated with a significantly greater risk for repeat operations in patients with diabetes who require lumbar surgery, a new study suggests.

The risk for additional surgeries was even higher among patients taking the popular weight loss and diabetes drug for longer periods of time.

Investigators say the study provides the first evidence on the impact of semaglutide on spine surgery. 

“The expectation was [that] we would see patients doing better after surgery, less wound complications, and other things, and in our diabetic patients we did not see that and saw increased odds of needing additional surgeries,” investigator Syed I. Khalid, MD, neurosurgery resident at University of Illinois Chicago, told this news organization.

The findings were presented on May 3 at the American Association of Neurological Surgeons (AANS) 2024 Annual Meeting.
 

Additional Surgery at Year 1

The new study used the all-payer Mariner database to identify patients aged 18-74 years with type 2 diabetes who underwent elective one- to three-level transforaminal lumbar interbody fusions (TLIFs) between January 2018 and October 2022. 

Patients were matched in a 3:1 ratio for age, sex, hypertension, obesity, smoking history, chronic kidney disease, osteoporosis, insulin use, and spinal fusion level, resulting in 447 patients with semaglutide use and 1334 with no semaglutide use. More than half (56%) were female, 62% used insulin, and 81% underwent single-level TLIF.

Total medical complications were higher in the semaglutide group, at 13.4%, compared with 7.7% in the no-semaglutide group (odds ratio [OR], 1.85). This was driven by higher rates of urinary tract infection (6.7% vs 2.5%) and acute kidney injury (6.3% vs 3.9%), two complications observed with semaglutide in other studies, Dr. Khalid said.

Total surgical complications, however, were lower in patients taking semaglutide, at 3.8% vs 5.2% in those who did not (OR, 0.73). 

Patients taking semaglutide vs those who were not using semaglutide had fewer wound healing complications (5 vs 31), hematoma (1 vs 9), surgical-site infections (12 vs 44), and cerebrospinal fluid leaks (2 vs 3).

Still, people taking semaglutide were nearly 12 times more likely to have an additional lumbar surgery at 1 year than did those who did not use the drug (27.3% vs 3.1%; OR, 11.79; 95% CI, 8.17-17.33).

Kaplan-Meier plots revealed a striking divergence of these populations when semaglutide exposure for more than or less than 9 months was examined (log-rank P < .0001).

Currently under review for publication, this study provides the first evidence on the impact of semaglutide on spine surgery, Dr. Khalid said. A second follow-up paper, also under review, looked only at patients with patients morbidly obesity without diabetes who had taken semaglutide for weight loss. 

“In nondiabetic, morbidly obese patients undergoing spine surgery, we see a similar trend,” Dr. Khalid said.
 

Sarcopenia the Cause?

The additional surgeries were primarily extensions of constructs, with additional surgery and fusion at more levels, Dr. Khalid noted. 

“The idea is that it could be the fact there is sarcopenia or muscle loss that’s taking place in conjunction with fat loss that’s causing that to happen,” Dr. Khalid said.

The mechanism remains speculative, but evidence from other areas examining frailty states has shown that those patients have weaker bones, sarcopenia, and worse outcomes with spine surgery, he noted. 

The investigators plan to use artificial intelligence to evaluate changes in body composition after semaglutide use in patients who underwent imaging prior to spine surgery or even before back pain occurred. Because these medications are uptitrated over time, follow-up studies will also look at whether this change takes place with a certain dose, Dr. Khalid added. 

On the basis of the current analysis of generic semaglutide alone, it’s not possible to say whether the use of other glucagon-like peptide 1 (GLP-1) receptor agonists will result in similar findings, but “the odds of a class effect are high,” Dr. Khalid said. 

Commenting on the findings, Walavan Sivakumar, MD, director of neurosurgery at Pacific Neuroscience Institute, Los Angeles, noted that the timing of surgery is already an issue for patients taking semaglutide and other GLP-1 receptor agonists following recent guidance from the American Society of Anesthesiologists that suggests stopping GLP-1 receptor agonists prior to elective surgery to reduce the risk for complications associated with anesthesia.

“It’s an incredibly topical point and seems to be something showing up on a daily basis for clinicians all throughout neurosurgery,” Dr. Sivakumar said. “It’s thought-provoking and a great first start.” 

Dr. Sivakumar also observed that frailty is a hot topic in all of neurosurgery. “That’s a major, major point that’s showing an impact on all surgical outcomes and it’s being heavily studied in the neurosurgical subsets right now. So that’s definitely a possible correlating factor.”

Dr. Khalid reported no financial relationships. Dr. Sivakumar reported serving as a consultant for Stryker.

Sherrie Palm, a patient advocate in Mukwonago, Wisconsin, learned in her 30s that she needed to educate herself about her own health. So when she discovered a walnut-sized lump coming out of her vagina in her mid-50s, she was stunned when her primary care provider (PCP) told her it was pelvic organ prolapse (POP), where one or more organs descend into the vaginal cavity.

“I was shocked,” Ms. Palm said. After searching online and discovering how prevalent POP was, her shock turned to anger. “I was blown away that it could be this common and I’d never heard of it,” she said. “I knew within 2 weeks that I had to do something to change the status quo.”

Ms. Palm eventually founded the nonprofit Association for Pelvic Organ Prolapse Support, or APOPS, complete with a forum where women can learn about POP and support one another. She said awareness has improved substantially since her diagnosis in 2007, but “we have a long way to go” because POP and vaginal health in general are so stigmatized.

Her website notes that about half of women with incontinence do not seek help, largely because of stigma. “The status quo is that PCPs do not POP screen,” she said. ObGyns may screen but often “because the patient has asked to be screened, they say it’s not that bad, come back and see me in a year, and do your Kegels,” Ms. Palm said.

Doctors who diagnose POP agree that the issue is often off PCPs’ radar.

“Primary care doctors are really in a time crunch, so this is one of the things that may not get addressed,” Jill Rabin, MD, vice chair of education and development in obstetrics and gynecology at Northwell Health in New York, said. Dr. Rabin is also head of urogynecology at Long Island Jewish Medical Center.

Ann Nwabuebo, PT, DPT, owner and founder of Body Connect Physical Therapy in Bethesda, Maryland, said social media has been shifting the attitude that pelvic health is a taboo subject. “It’s empowering people to seek care if they’re not finding physicians who are helping.”

But social media is also a double-edged sword, said Jenny LaCross, PT, DPT, PhD, a physical therapist at MOVE PT in Monroe, Michigan, and a postdoctoral research fellow with Michigan Medicine’s Pelvic Floor Research Group. “Pelvic health in general is talked about a lot more, but there’s also a lot more misinformation,” she said.

Part of that misinformation is the idea that pelvic prolapse is solely about weakness in the pelvic floor when it can also result from a widening of natural openings within the pelvis, Dr. LaCross said. She pointed to the two definitions of pelvic organ prolapse by the International Urogynecologic Consultation and the International Continence Society, both of which have been updated in recent years.

“This is why this is challenging for primary care providers,” Dr. LaCross said. “Even urogynecologists who are the specialists that treat prolapse and incontinence have changed how they assess it and the terminology and criteria that they use.”

What hasn’t changed is the substantial negative impact POP can have on quality of life. “This is the second most common reason that women enter nursing homes,” primarily because of urinary incontinence, Dr. Rabin said. “It’s very debilitating, but a lot of it is preventable and a lot is treatable.”

Dr. Rabin estimated that three out of every five women older than 60 and one or two out of every five women younger than 60 experience POP. Prevalence studies vary widely, from nearly a quarter of women to more than half, and racial and ethnic disparities in diagnosis further complicate the statistics.

PCPs therefore have an important role to play in screening for POP. The evidence shows that “patients want their providers to bring this up,” Dr. LaCross said. “They want to talk about it, but they want the provider to ask the questions first.”
 

Causes, Risk Factors, and Symptoms

Many causes contribute to POP, with gravity, aging, childbirth, and menopause at the top of the list.

“As people get older, their pelvic muscles and connective tissue get weaker, and the nerves don’t function as well,” Dr. Rabin said. Meanwhile, the body is losing estrogen, which affects how well the muscles contract and how easily the connective tissue can tear, she said.

With menopause, when baseline estrogen is lower, the tissue integrity is not as supportive as it should be and women are going to be at an increased risk of prolapse, Dr. Nwabuebo said.

POP has a range of risk factors:

• Increasing age, as muscle mass decreases and connective tissue hardens.
• Menopause.
• Vaginal delivery with complications, such as long second-stage labor, instrument-assisted delivery, multiple vaginal lacerations, and improperly repaired episiotomy.
• Multiple vaginal deliveries.
• Birthing large babies.
• Family history of pelvic organ prolapse (genetics can play a role in POP risk).
• Previous pelvic/abdominal surgery, including cesarean delivery and hysterectomy.
• Smoking (largely because of associated coughing).
• Chronic lung conditions that cause a lot of coughing.
• Chronic constipation or irritable bowel syndrome.
• Some types of high-impact activity, such as jogging or marathon running.
• Early menopause, for younger women.
• Repetitive heavy lifting in daily activities, such as occupational lifting (though not necessarily weight lifting as an exercise).
• Higher body mass index.
• Connective tissue disorders, such as joint hypermobility syndrome or Ehlers-Danlos syndrome.

Roger Dmochowski, MD, professor of urology and surgery at Vanderbilt University Medical Center, groups POP symptoms into two groups: anatomic and functional ones. A common anatomic symptom is bulging. “They’ll describe sitting on a ball, feeling like their bladder or something’s falling out, feeling a pressure or a heaviness,” Dr. Dmochowski said.

Functional symptoms can include vaginal dryness, vaginal irritation, painful intercourse, contact of the vaginal tissues with underclothes, and associated urinary symptoms, such as stress incontinence, urge incontinence, and incomplete emptying of the bladder. Dr. Dmochowski noted that women who report urinary incontinence may be at risk for being prescribed a medication without the necessary referral to a specialist for a full gynecologic evaluation.

Two other groups of functional symptoms include bowel-related disorders – primarily fecal incontinence and ongoing constipation – and pelvic pain or discomfort.

There can also be asymptomatic cases. “A lot of women have what we call silent prolapse,” Dr. Dmochowski said. That is, “they have some degree of loss of support to the bladder, vagina, or uterus, but they’re not symptomatic.” These women may be particularly good candidates for pelvic health physical therapy.
 

Screening and Diagnosis

Because many postmenopausal women stop seeing their ob.gyn, it’s often up to their primary care physician to determine whether their patients are experiencing POP symptoms.

“Women sometimes don’t bring this up with their doctor because they think there’s not enough time, or they’ll be laughed at, or their friends told them this is normal,” Dr. Rabin said. But primary care providers are really in a unique position to be able to ask the key symptom questions.

Dr. Rabin recommends a couple of questions to cover all the bases: “Do you leak urine when you cough or sneeze or on the way to the bathroom? Do you notice a bulge coming out of the vagina, or are you bothered by pelvic pressure?”

Dr. Dmochowski offered a single question that can open the conversation to more questions: “Are you bothered by any urinary or bowel or vaginal issues that we should talk about?” He also suggests asking how bothersome the symptoms are, which can help in directing treatment or prevention options. A physical exam can reveal signs of POP as well.

Diagnosis involves a detailed history, a comprehensive physical exam, and assessment with the Pelvic Organ Prolapse Quantification (POP-Q) tool. A urogynecologist can diagnose the type of POP – such as cystocele, rectocele, enterocele, uterine prolapse, or vaginal vault prolapse – and its grade (0-4).
 

Treatment: Physical Therapy, Pessary, and Surgery

No medications can treat prolapse, though some can treat downstream effects, such as hormonal vaginal creams for vaginal dryness and irritation, and medications for urinary incontinence. However, two mistakes PCPs can make are sending someone straight to surgery or prescribing them medication for symptoms without referring them for a diagnostic evaluation, Dr. Rabin said. “You have to have a diagnosis first to know what type of prolapse is there,” she said.

Because there can be long waiting lists for a urogynecologist or urologist, PCPs should also refer their patients to a pelvic health physical therapist (PT) who can help patients begin addressing the symptoms while they await a specialist who can diagnose them.

Though PT is often thought of as preventive, it’s also a conservative first-line intervention for prolapse, Dr. Nwabuebo said. Strong evidence shows pelvic floor muscle training from pelvic health PT can reduce symptoms of prolapse and reduce the severity by one grade in those with a grade 1 or 2 prolapse. Stage 3 is trickier, where PT may or may not be able to shift the symptom presentation, Dr. Nwabeubo said, and stage 4 is usually a surgical candidate.

“If you have a grade 4 prolapse, or the tissues are really visible outside the body, physical therapy and pelvic floor muscle training is not going to elevate that tissue back up into your body, but it can sometimes help with symptoms,” Dr. LaCross said.

The PT conducts a thorough pelvic muscle assessment, discusses lifestyle, and may teach breathing and bracing strategies for lifting, for example.

“A lot of what we’re talking about with pelvic floor therapy is lifestyle modifications,” Dr. Nwabuebo said. “If I have a patient with a history of chronic constipation, it doesn’t matter how much we do pelvic floor exercises; if we don’t manage the constipation issues by addressing their nutrition, then straining when using the bathroom will keep putting pressure on the pelvic floor.”

PTs can also recommend appropriate vaginal weights and dilators to help with pelvic floor strengthening and teach patients how to use them properly.

Even if women ultimately opt for surgery, PT prior to surgery can be beneficial. Dr. Rabin cited three reasons she recommends first-line PT: It may elevate the bladder enough to reduce stress incontinence and thicken the pelvic muscles, it can improve the effectiveness of a pessary or surgery if the woman chooses one of those options, and it can quiet bladder contractions, potentially obviating the need for pharmacologic treatment for overactive bladder.

The next nonsurgical option is a pessary, a device that fits into the vagina to provide support to the tissues displaced by prolapse. There’s a wide range of pessary types: some are short-term, worn only daily, or disposable, while others can be worn longer. Some women can self-insert and remove the pessary, and others may need a clinician to do so. Dr. Dmochowski recommends patients try a pessary to see if it benefits them. About a third of women will find them comfortable enough to wear regularly, but others will feel more sensitive to the pessary’s presence, he said.

One of the newest, most innovative pessary options for women is Gynethotics, which received Food and Drug Administration (FDA) clearance in March, as the first 3D-printed, customizable pessary capable of nearly 10 million configurations based on a person’s body.

Nearly all stage 4 prolapses and most of stage 3 prolapses can be addressed only through transvaginal or transabdominal surgery.

“We tell patients, if you can get 10 years out of your operation, you’re lucky,” Dr. Dmochowski said. A major reason for the short-lived durability is the poor quality of the tissue that needs to be pulled together. Serious complications resulting from use of polypropylene mesh during prolapse surgery led the FDA to halt sales of the devices and recommend discontinuing their use. However, one type of vaginal mesh is still considered safe to use in sacral colpopexy surgery.

Three things can shorten the durability of the surgery, Dr. Dmochowski said: heavy lifting, particularly anything over 30 pounds; chronic coughing, such as in those with chronic lung conditions; and chronic constipation.

Ms. Palm tried a pessary for her grade 3 prolapse with cystocele, rectocele, and enterocele but didn’t feel she had the time to use it regularly, so she opted for surgery. After a week on the couch recovering, she took it easy for another 12 weeks. Since then, she’s dedicated much of her time to educating and supporting women with POP and combating stigma associated with it. The APOPS website that she started has become a valuable resource for PCPs to send patients to, and the forum includes more 27,000 women from around the world.

“We encourage women to share what they’re experiencing. Tell your family, tell your friends, tell the people you work with about it,” Ms. Palm said. But many still feel uncomfortable speaking up, making PCPs’ role even more important.

Sherrie Palm, a patient advocate in Mukwonago, Wisconsin, learned in her 30s that she needed to educate herself about her own health. So when she discovered a walnut-sized lump coming out of her vagina in her mid-50s, she was stunned when her primary care provider (PCP) told her it was pelvic organ prolapse (POP), where one or more organs descend into the vaginal cavity.

“I was shocked,” Ms. Palm said. After searching online and discovering how prevalent POP was, her shock turned to anger. “I was blown away that it could be this common and I’d never heard of it,” she said. “I knew within 2 weeks that I had to do something to change the status quo.”

Ms. Palm eventually founded the nonprofit Association for Pelvic Organ Prolapse Support, or APOPS, complete with a forum where women can learn about POP and support one another. She said awareness has improved substantially since her diagnosis in 2007, but “we have a long way to go” because POP and vaginal health in general are so stigmatized.

Her website notes that about half of women with incontinence do not seek help, largely because of stigma. “The status quo is that PCPs do not POP screen,” she said. ObGyns may screen but often “because the patient has asked to be screened, they say it’s not that bad, come back and see me in a year, and do your Kegels,” Ms. Palm said.

Doctors who diagnose POP agree that the issue is often off PCPs’ radar.

“Primary care doctors are really in a time crunch, so this is one of the things that may not get addressed,” Jill Rabin, MD, vice chair of education and development in obstetrics and gynecology at Northwell Health in New York, said. Dr. Rabin is also head of urogynecology at Long Island Jewish Medical Center.

Ann Nwabuebo, PT, DPT, owner and founder of Body Connect Physical Therapy in Bethesda, Maryland, said social media has been shifting the attitude that pelvic health is a taboo subject. “It’s empowering people to seek care if they’re not finding physicians who are helping.”

But social media is also a double-edged sword, said Jenny LaCross, PT, DPT, PhD, a physical therapist at MOVE PT in Monroe, Michigan, and a postdoctoral research fellow with Michigan Medicine’s Pelvic Floor Research Group. “Pelvic health in general is talked about a lot more, but there’s also a lot more misinformation,” she said.

Part of that misinformation is the idea that pelvic prolapse is solely about weakness in the pelvic floor when it can also result from a widening of natural openings within the pelvis, Dr. LaCross said. She pointed to the two definitions of pelvic organ prolapse by the International Urogynecologic Consultation and the International Continence Society, both of which have been updated in recent years.

“This is why this is challenging for primary care providers,” Dr. LaCross said. “Even urogynecologists who are the specialists that treat prolapse and incontinence have changed how they assess it and the terminology and criteria that they use.”

What hasn’t changed is the substantial negative impact POP can have on quality of life. “This is the second most common reason that women enter nursing homes,” primarily because of urinary incontinence, Dr. Rabin said. “It’s very debilitating, but a lot of it is preventable and a lot is treatable.”

Dr. Rabin estimated that three out of every five women older than 60 and one or two out of every five women younger than 60 experience POP. Prevalence studies vary widely, from nearly a quarter of women to more than half, and racial and ethnic disparities in diagnosis further complicate the statistics.

PCPs therefore have an important role to play in screening for POP. The evidence shows that “patients want their providers to bring this up,” Dr. LaCross said. “They want to talk about it, but they want the provider to ask the questions first.”
 

Causes, Risk Factors, and Symptoms

Many causes contribute to POP, with gravity, aging, childbirth, and menopause at the top of the list.

“As people get older, their pelvic muscles and connective tissue get weaker, and the nerves don’t function as well,” Dr. Rabin said. Meanwhile, the body is losing estrogen, which affects how well the muscles contract and how easily the connective tissue can tear, she said.

With menopause, when baseline estrogen is lower, the tissue integrity is not as supportive as it should be and women are going to be at an increased risk of prolapse, Dr. Nwabuebo said.

POP has a range of risk factors:

• Increasing age, as muscle mass decreases and connective tissue hardens.
• Menopause.
• Vaginal delivery with complications, such as long second-stage labor, instrument-assisted delivery, multiple vaginal lacerations, and improperly repaired episiotomy.
• Multiple vaginal deliveries.
• Birthing large babies.
• Family history of pelvic organ prolapse (genetics can play a role in POP risk).
• Previous pelvic/abdominal surgery, including cesarean delivery and hysterectomy.
• Smoking (largely because of associated coughing).
• Chronic lung conditions that cause a lot of coughing.
• Chronic constipation or irritable bowel syndrome.
• Some types of high-impact activity, such as jogging or marathon running.
• Early menopause, for younger women.
• Repetitive heavy lifting in daily activities, such as occupational lifting (though not necessarily weight lifting as an exercise).
• Higher body mass index.
• Connective tissue disorders, such as joint hypermobility syndrome or Ehlers-Danlos syndrome.

Roger Dmochowski, MD, professor of urology and surgery at Vanderbilt University Medical Center, groups POP symptoms into two groups: anatomic and functional ones. A common anatomic symptom is bulging. “They’ll describe sitting on a ball, feeling like their bladder or something’s falling out, feeling a pressure or a heaviness,” Dr. Dmochowski said.

Functional symptoms can include vaginal dryness, vaginal irritation, painful intercourse, contact of the vaginal tissues with underclothes, and associated urinary symptoms, such as stress incontinence, urge incontinence, and incomplete emptying of the bladder. Dr. Dmochowski noted that women who report urinary incontinence may be at risk for being prescribed a medication without the necessary referral to a specialist for a full gynecologic evaluation.

Two other groups of functional symptoms include bowel-related disorders – primarily fecal incontinence and ongoing constipation – and pelvic pain or discomfort.

There can also be asymptomatic cases. “A lot of women have what we call silent prolapse,” Dr. Dmochowski said. That is, “they have some degree of loss of support to the bladder, vagina, or uterus, but they’re not symptomatic.” These women may be particularly good candidates for pelvic health physical therapy.
 

Screening and Diagnosis

Because many postmenopausal women stop seeing their ob.gyn, it’s often up to their primary care physician to determine whether their patients are experiencing POP symptoms.

“Women sometimes don’t bring this up with their doctor because they think there’s not enough time, or they’ll be laughed at, or their friends told them this is normal,” Dr. Rabin said. But primary care providers are really in a unique position to be able to ask the key symptom questions.

Dr. Rabin recommends a couple of questions to cover all the bases: “Do you leak urine when you cough or sneeze or on the way to the bathroom? Do you notice a bulge coming out of the vagina, or are you bothered by pelvic pressure?”

Dr. Dmochowski offered a single question that can open the conversation to more questions: “Are you bothered by any urinary or bowel or vaginal issues that we should talk about?” He also suggests asking how bothersome the symptoms are, which can help in directing treatment or prevention options. A physical exam can reveal signs of POP as well.

Diagnosis involves a detailed history, a comprehensive physical exam, and assessment with the Pelvic Organ Prolapse Quantification (POP-Q) tool. A urogynecologist can diagnose the type of POP – such as cystocele, rectocele, enterocele, uterine prolapse, or vaginal vault prolapse – and its grade (0-4).
 

Treatment: Physical Therapy, Pessary, and Surgery

No medications can treat prolapse, though some can treat downstream effects, such as hormonal vaginal creams for vaginal dryness and irritation, and medications for urinary incontinence. However, two mistakes PCPs can make are sending someone straight to surgery or prescribing them medication for symptoms without referring them for a diagnostic evaluation, Dr. Rabin said. “You have to have a diagnosis first to know what type of prolapse is there,” she said.

Because there can be long waiting lists for a urogynecologist or urologist, PCPs should also refer their patients to a pelvic health physical therapist (PT) who can help patients begin addressing the symptoms while they await a specialist who can diagnose them.

Though PT is often thought of as preventive, it’s also a conservative first-line intervention for prolapse, Dr. Nwabuebo said. Strong evidence shows pelvic floor muscle training from pelvic health PT can reduce symptoms of prolapse and reduce the severity by one grade in those with a grade 1 or 2 prolapse. Stage 3 is trickier, where PT may or may not be able to shift the symptom presentation, Dr. Nwabeubo said, and stage 4 is usually a surgical candidate.

“If you have a grade 4 prolapse, or the tissues are really visible outside the body, physical therapy and pelvic floor muscle training is not going to elevate that tissue back up into your body, but it can sometimes help with symptoms,” Dr. LaCross said.

The PT conducts a thorough pelvic muscle assessment, discusses lifestyle, and may teach breathing and bracing strategies for lifting, for example.

“A lot of what we’re talking about with pelvic floor therapy is lifestyle modifications,” Dr. Nwabuebo said. “If I have a patient with a history of chronic constipation, it doesn’t matter how much we do pelvic floor exercises; if we don’t manage the constipation issues by addressing their nutrition, then straining when using the bathroom will keep putting pressure on the pelvic floor.”

PTs can also recommend appropriate vaginal weights and dilators to help with pelvic floor strengthening and teach patients how to use them properly.

Even if women ultimately opt for surgery, PT prior to surgery can be beneficial. Dr. Rabin cited three reasons she recommends first-line PT: It may elevate the bladder enough to reduce stress incontinence and thicken the pelvic muscles, it can improve the effectiveness of a pessary or surgery if the woman chooses one of those options, and it can quiet bladder contractions, potentially obviating the need for pharmacologic treatment for overactive bladder.

The next nonsurgical option is a pessary, a device that fits into the vagina to provide support to the tissues displaced by prolapse. There’s a wide range of pessary types: some are short-term, worn only daily, or disposable, while others can be worn longer. Some women can self-insert and remove the pessary, and others may need a clinician to do so. Dr. Dmochowski recommends patients try a pessary to see if it benefits them. About a third of women will find them comfortable enough to wear regularly, but others will feel more sensitive to the pessary’s presence, he said.

One of the newest, most innovative pessary options for women is Gynethotics, which received Food and Drug Administration (FDA) clearance in March, as the first 3D-printed, customizable pessary capable of nearly 10 million configurations based on a person’s body.
