If you’re looking to grow hair, you might just have a solution in your kitchen cabinet – if TikTok and some dermatologists are correct.

A small study published in 2015 suggested that rosemary oil may help regrow hair in people with androgenetic alopecia. The herb might also protect hair from the sun, pollution, and other environmental elements, according to an article in Insider.

The study published in Skinmed found that rosemary oil was similar to the effectiveness of minoxidil for regrowing hair in men with androgenetic alopecia. The scalp was also less itchy after 3-6 months of use.

The study included only men.

Still, dermatologist Shilpi Khetarpal, MD, told the Cleveland Clinic that it seems to work.

“The study really prompted people to look at rosemary oil for hair growth,” she said. “It became much more common in over-the-counter products after that, too.”

The Cleveland Clinic also reports that rosemary oil might help against dandruff and premature graying.

Dr. Khetarpal suggested massaging rosemary oil into the scalp, letting it soak overnight, and then washing it out. This should be done two or three times a week. 

She also noted that only a few drops of rosemary oil are needed, and that the focus should be on the scalp rather than the hair, which rosemary oil makes look greasy.

It may take 6 months for “meaningful improvement,” Dr. Khetarpal said.

Meanwhile, TikTok users love hyping the oil’s hair care qualities. On the social media platform, videos with the hashtag #rosemaryoil have been viewed more than 2 billion times.

When OpenAI released ChatGPT-3 publicly last November, some doctors decided to try out the free AI tool that learns language and writes human-like text. Some physicians found the chatbot made mistakes and stopped using it, while others were happy with the results and plan to use it more often.

“We’ve played around with it. It was very early on in AI and we noticed it gave us incorrect information with regards to clinical guidance,” said Monalisa Tailor, MD, an internal medicine physician at Norton Health Care in Louisville, Ky. “We decided not to pursue it further,” she said.

Orthopedic spine surgeon Daniel Choi, MD, who owns a small medical/surgical practice in Long Island, New York, tested the chatbot’s performance with a few administrative tasks, including writing a job listing for an administrator and prior authorization letters.

He was enthusiastic. “A well-polished job posting that would usually take me 2-3 hours to write was done in 5 minutes,” Dr. Choi said. “I was blown away by the writing – it was much better than anything I could write.”

The chatbot can also automate administrative tasks in doctors’ practices from appointment scheduling and billing to clinical documentation, saving doctors time and money, experts say.

Most physicians are proceeding cautiously. About 10% of more than 500 medical group leaders, responding to a March poll by the Medical Group Management Association, said their practices regularly use AI tools.

More than half of the respondents not using AI said they first want more evidence that the technology works as intended.

“None of them work as advertised,” said one respondent.

MGMA practice management consultant Dawn Plested acknowledges that many of the physician practices she’s worked with are still wary. “I have yet to encounter a practice that is using any AI tool, even something as low-risk as appointment scheduling,” she said.

Physician groups may be concerned about the costs and logistics of integrating ChatGPT with their electronic health record systems (EHRs) and how that would work, said Ms. Plested.

Doctors may also be skeptical of AI based on their experience with EHRs, she said.

“They were promoted as a panacea to many problems; they were supposed to automate business practice, reduce staff and clinician’s work, and improve billing/coding/documentation. Unfortunately, they have become a major source of frustration for doctors,” said Ms. Plested.
 

Drawing the line at patient care

Patients are worried about their doctors relying on AI for their care, according to a Pew Research Center poll released in February. About 60% of U.S. adults say they would feel uncomfortable if their own health care professional relied on artificial intelligence to do things like diagnose disease and recommend treatments; about 40% say they would feel comfortable with this.

“We have not yet gone into using ChatGPT for clinical purposes and will be very cautious with these types of applications due to concerns about inaccuracies,” Dr. Choi said.

Practice leaders reported in the MGMA poll that the most common uses of AI were nonclinical, such as:

• Patient communications, including call center answering service to help triage calls, to sort/distribute incoming fax messages, and outreach such as appointment reminders and marketing materials.
• Capturing clinical documentation, often with natural language processing or speech recognition platforms to help virtually scribe.
• Improving billing operations and predictive analytics.

Some doctors told The New York Times that ChatGPT helped them communicate with patients in a more compassionate way.

They used chatbots “to find words to break bad news and express concerns about a patient’s suffering, or to just more clearly explain medical recommendations,” the story noted.
 

Is regulation needed?

Some legal scholars and medical groups say that AI should be regulated to protect patients and doctors from risks, including medical errors, that could harm patients.

“It’s very important to evaluate the accuracy, safety, and privacy of language learning models (LLMs) before integrating them into the medical system. The same should be true of any new medical tool,” said Mason Marks, MD, JD, a health law professor at the Florida State University College of Law in Tallahassee.

In mid-June, the American Medical Association approved two resolutions calling for greater government oversight of AI. The AMA will develop proposed state and federal regulations and work with the federal government and other organizations to protect patients from false or misleading AI-generated medical advice.

Dr. Marks pointed to existing federal rules that apply to AI. “The Federal Trade Commission already has regulation that can potentially be used to combat unfair or deceptive trade practices associated with chatbots,” he said.

In addition, “the U.S. Food and Drug Administration can also regulate these tools, but it needs to update how it approaches risk when it comes to AI. The FDA has an outdated view of risk as physical harm, for instance, from traditional medical devices. That view of risk needs to be updated and expanded to encompass the unique harms of AI,” Dr. Marks said.

There should also be more transparency about how LLM software is used in medicine, he said. “That could be a norm implemented by the LLM developers and it could also be enforced by federal agencies. For instance, the FDA could require developers to be more transparent regarding training data and methods, and the FTC could require greater transparency regarding how consumer data might be used and opportunities to opt out of certain uses,” said Dr. Marks.
 

What should doctors do?

Dr. Marks advised doctors to be cautious when using ChatGPT and other LLMs, especially for medical advice. “The same would apply to any new medical tool, but we know that the current generation of LLMs [is] particularly prone to making things up, which could lead to medical errors if relied on in clinical settings,” he said.

There is also potential for breaches of patient confidentiality if doctors input clinical information. ChatGPT and OpenAI-enabled tools may not be compliant with the Health Insurance Portability and Accountability Act, which set national standards to protect individuals’ medical records and individually identifiable health information.

“The best approach is to use chatbots cautiously and with skepticism. Don’t input patient information, confirm the accuracy of information produced, and don’t use them as replacements for professional judgment,” Dr. Marks recommended.

Ms. Plested suggested that doctors who want to experiment with AI start with a low-risk tool such as appointment reminders that could save staff time and money. “I never recommend they start with something as high-stakes as coding/billing,” she said.

After her emergency medicine group was acquired by a staffing firm backed by a large private equity (PE) firm, Michelle Wiener, MD, said the workflow changes came swiftly.

“Our staffing has been greatly reduced,” the Detroit physician said. “At this point, we have no say in anything. We have no say in the scheduling. We aren’t allowed to see what is billed under our name. The morale has really gone down.”

Dr. Wiener, who practices at Ascension St. John Hospital, said she and fellow physicians have repeatedly brought their concerns to TeamHealth, which in 2015 took over St. John Emergency Services PC. TeamHealth is owned by PE giant Blackstone.

“It’s very frustrating,” Dr. Wiener said. “We’re taking it from all sides.”

Blackstone and Ascension St. John did not respond to this news organization’s request for comment.

TeamHealth would not respond directly to questions about the Ascension St. John Hospital physicians or their concerns.

Spokesman Josh Hopson provided only a general statement: “TeamHealth is committed to making sure that clinicians have the resources and support needed to provide first-class care to patients, particularly with regard to staffing and compensation. TeamHealth has and will always put patient care first, and that is not impacted by its ownership model.”

Acquisitions of medical practices and hospitals by PE firms are rapidly growing, with more than 1,400 PE deals in health care in 2021 totaling upwards of $208 billion, according to PitchBook Data Inc., a Seattle-based firm that tracks mergers and acquisitions.

Some physicians praise the partnerships as an opportunity to improve technology and efficiency, whereas others decry them as raising patient costs and lowering the quality of care. A recent UC Berkeley study found that PE ownership of medical practices was linked to consumer price increases for 8 of 10 specialties, most notably oncology and gastroenterology.
 

What should you expect after PE acquisition?

Since his practice partnered with a PE firm in 2020, Milwaukee-based otolaryngologist Madan Kandula, MD, said he has found the changes positive. The practice has grown and improved operations in finance, accounting, compliance, and information technology, said Dr. Kandula, founder and CEO of Advent, an ENT practice with 15 clinics in four Midwestern states.

Dr. Kandula said his group already had a sound business practice, and that the goal of partnering with a PE firm wasn’t to change day-to-day operations but to propel the organization forward.

“From patient load to visit time to how we staff our clinics, there has been no change,” he said. “My private equity firm does not, [and] cannot, impose their will on our clinical decisions.”

Experts say the impact of PE acquisitions on individual physicians often depends on where a doctor ranks in the organization, what stage they are in their career, and how much control they had over the deal.

“It’s the older physicians who are usually selling the practice and getting the big payout,” said Anjali Dooley, a St. Louis–based health law attorney who counsels physicians about PE deals. “The younger doctors are usually not part of the deal, as they may still be employees. They don’t have any negotiating power. Hopefully, there is some transparency, but sometimes there is not, and they are blindsided by the deal.”

When it comes to workload, most PE-owned groups are put on a production-based model, such as a wRVU-based model, said Roger Strode, a Chicago-based health law attorney who focuses on health care mergers and acquisitions. Most already operate under such a model, but there might be some changes after a buyout.

Staffing may also change, added Ms. Dooley. The PE firms may want to add partners or companies already in their portfolios to create efficiencies, causing training or workflow changes.

In a hospital buyout, changes may depend on whether a department is a significant revenue generator for the hospital, Ms. Dooley noted.

PE firms frequently favor higher revenue–generating specialties, such as neurosurgery, cardiology, orthopedics, gastroenterology, and plastic surgery. They closely scrutinize departments said that make less money, such as the emergency department or primary care, Ms. Dooley said. Physicians or teams that don’t fit the firm’s cost-efficiency plans may be terminated or replaced.

On the other hand, Mr. Strode said physicians may see improved electronic health records and collections.

“Some of your overall overhead costs may be reduced, because they’re better at it,” Mr. Strode said. “When you’ve got more scale, the cost per patient, the cost per hour, the cost per procedure, goes down, and the cost that’s applied against your production will go down. As [practices grow], they have more bargaining power with payers and you can potentially get better rates. At least, that’s the promise.”

Analysts note that PE health care acquisitions show no signs of slowing and that it pays for physicians to know what to expect and how to cope if their practice or hospital is acquired. Whether physicians have some control over a buyout or are blindsided by the transition, it’s critical to know what to consider, how workloads might change, and your options for settling in or settling up.

The PE industry has about $2 trillion lined up for potential investments in 2023, said Ms. Dooley.

“PE firms are looking at health care to expend some of this dry powder,” Ms. Dooley continued. “If done correctly, PE firms that are aware of health care regulations, compliance, and patient care issues can ... remove redundant services and improve ... efficiencies, but the bad is when that doesn’t happen, and the quality of care goes down or there are patient safety risks.”
 

How to prepare for and cope with PE partnerships

If your practice is considering a PE partnership, it’s important to explore the terms and conditions and carefully weigh the pros and cons, said Gary Herschman, a Newark, N.J.–based attorney who advises PE-owned physician groups.

“My recommendation is that physicians at a minimum conduct due diligence on all potential strategic options for their groups, and then make an informed decision regarding whether a partnership transaction is right for their group, as it’s not right for every group,” he said.

When Texas cardiologist Rick Snyder, MD, was considering PE partnerships, he spoke with physicians who made similar deals to determine whether they were satisfied years later, he said. In April, Snyder’s practice, HeartPlace, the largest physician-owned cardiology practice in Texas, was acquired by US Heart & Vascular, a practice management platform backed by PE firm Ares Management.

“I called every group that I knew that had done private equity for any meaningful amount of time,” Dr. Snyder said. “For the first year or two, everybody is in the honeymoon period. If the model is going to succeed or break down, it’s not going to be in the first year or two. So I wanted to talk to groups that had done this for a longer amount of time and find out what their pitfalls were. What would they have done differently? Has it been a productive relationship? Did they grow?”

Dr. Snyder, president of the Texas Medical Association, said his practice met with seven or eight firms before choosing one that best met their needs. His group wanted a platform that preserved their clinical autonomy, governance, and culture, he said. They also wanted to ensure they were not entering into a “buy and flip” scenario, but rather a “buy and build” plan.

“Thus, financial capital was not sufficient, they also had to have intellectual capital and relationship capital on their bench,” he said. “When we found the partner that embraced all of these factors as well as a history of buying and long-term building, we pulled the trigger and partnered with Ares and US Heart & Vascular Management. The partner we chose did not offer us the most money. We put a premium on these other criteria.”

“I always tell docs, know the culture of your group and your vision,” he said. “Before you go down that route, ask yourself what you want to accomplish and if it makes sense having a private equity partner to accomplish that vision with.”

For younger physicians or those with little control over buyouts, experts recommend they review their contracts and consider consulting with an attorney to better understand how the deal may affect their earnings and career prospects.

Those who have a much longer career runway need to weigh whether they want to work for a PE-linked practice, Mr. Strode said. For some, it’s time to check when their noncompete agreements end and find a position elsewhere.

Also, physicians should know their rights and the laws in their states regarding the corporate practice of medicine. Statutes vary by state, and knowing the provisions in your state helps doctors recognize their legal rights, learn possible exceptions to the requirements, and know the penalties for violations.

In Michigan, a group of physicians and other health professionals at Ascension St. John has voted to unionize. Doctors hope that the union, which includes advanced practice clinicians, nurse practitioners, and physician assistants, will help improve patient care and protect working conditions for staff, Dr. Wiener said.

She advises physicians who are unhappy after acquisitions to speak up and stick together.

“That’s the biggest thing I think physicians should start doing,” she said. “Support each other and stand up. You are stronger together.”
 

Why is PE so attracted to health care?

PE firms typically buy practices or hospitals, work to make the entities more profitable, and then sell them, with the goal of doubling or tripling their investment over a short period. In general, PE firms aim for annual returns exceeding 20% after 3-7 years.

These firms know that health care is relatively recession-proof, that providers have third-party payers, and that the industry is fragmented and requires more efficiency, Ms. Dooley said.

When PE practice acquisitions started gaining momentum about 12 years ago, traditional hospital-based specialties such as anesthesiology and radiology were prime targets, said Mr. Strode.

At the same time, increasing challenges in private practice, such as declining compensation from payers, pressure to participate in value-based care programs, and rising regional competitors have fueled more physician groups to partner with PE firms, Mr. Herschman noted.

Physicians who partner with PE firms often benefit by having new access to capital to grow their practices, cost savings through group purchasing, and the ability to compete with larger health groups, Mr. Herschman said.

Questions remain, however, about how PE involvement affects health care use and spending. An April 2023 JAMA Viewpoint article called out the lack of oversight and regulation in the health care/PE space, suggesting that a stronger framework for regulation and transparency is needed.

A 2022 study in JAMA Health Forum that examined changes in prices and utilization associated with the PE acquisitions of 578 dermatology, gastroenterology, and ophthalmology physician practices from 2016 to 2020 found that prices increased by an average of 11%, and volume rose by 16%, after acquisition.

“We found that acquisitions were associated with increases in health care spending and utilization, as well as some other patterns of care like potential upcoding,” said Jane M. Zhu, MD, an author of the study and assistant professor at Oregon Health & Science University in Portland.

Another recent study that Dr. Zhu coauthored, published in Health Affairs, found that physician practices acquired by PE firms experience greater staff turnover and rely more heavily on advanced practice professionals than doctors.

“To the extent that that turnover indicates physicians are dissatisfied after private equity comes in, that’s really important to investigate further,” Dr. Zhu said.

PE firms owned 4% of U.S. hospitals in 2021 and 11% of nursing homes, according to a Medicare Payment Advisory Commission (MedPAC) report. The report does not include 2021 data on medical practices but notes that from 2013 to 2016, PE firms acquired at least 2% of physician practices. Estimates of PE deals are probably lower than actual numbers because of the lack of comprehensive information sources, according to the MedPAC report.

“Our staffing has been greatly reduced,” the Detroit physician said. “At this point, we have no say in anything. We have no say in the scheduling. We aren’t allowed to see what is billed under our name. The morale has really gone down.”

Dr. Wiener, who practices at Ascension St. John Hospital, said she and fellow physicians have repeatedly brought their concerns to TeamHealth, which in 2015 took over St. John Emergency Services PC. TeamHealth is owned by PE giant Blackstone.

“It’s very frustrating,” Dr. Wiener said. “We’re taking it from all sides.”

Blackstone and Ascension St. John did not respond to this news organization’s request for comment.

TeamHealth would not respond directly to questions about the Ascension St. John Hospital physicians or their concerns.

Spokesman Josh Hopson provided only a general statement: “TeamHealth is committed to making sure that clinicians have the resources and support needed to provide first-class care to patients, particularly with regard to staffing and compensation. TeamHealth has and will always put patient care first, and that is not impacted by its ownership model.”

Acquisitions of medical practices and hospitals by PE firms are rapidly growing, with more than 1,400 PE deals in health care in 2021 totaling upwards of $208 billion, according to PitchBook Data Inc., a Seattle-based firm that tracks mergers and acquisitions.

Some physicians praise the partnerships as an opportunity to improve technology and efficiency, whereas others decry them as raising patient costs and lowering the quality of care. A recent UC Berkeley study found that PE ownership of medical practices was linked to consumer price increases for 8 of 10 specialties, most notably oncology and gastroenterology.
 

What should you expect after PE acquisition?

Since his practice partnered with a PE firm in 2020, Milwaukee-based otolaryngologist Madan Kandula, MD, said he has found the changes positive. The practice has grown and improved operations in finance, accounting, compliance, and information technology, said Dr. Kandula, founder and CEO of Advent, an ENT practice with 15 clinics in four Midwestern states.

Dr. Kandula said his group already had a sound business practice, and that the goal of partnering with a PE firm wasn’t to change day-to-day operations but to propel the organization forward.

“From patient load to visit time to how we staff our clinics, there has been no change,” he said. “My private equity firm does not, [and] cannot, impose their will on our clinical decisions.”

Experts say the impact of PE acquisitions on individual physicians often depends on where a doctor ranks in the organization, what stage they are in their career, and how much control they had over the deal.

“It’s the older physicians who are usually selling the practice and getting the big payout,” said Anjali Dooley, a St. Louis–based health law attorney who counsels physicians about PE deals. “The younger doctors are usually not part of the deal, as they may still be employees. They don’t have any negotiating power. Hopefully, there is some transparency, but sometimes there is not, and they are blindsided by the deal.”

When it comes to workload, most PE-owned groups are put on a production-based model, such as a wRVU-based model, said Roger Strode, a Chicago-based health law attorney who focuses on health care mergers and acquisitions. Most already operate under such a model, but there might be some changes after a buyout.

Staffing may also change, added Ms. Dooley. The PE firms may want to add partners or companies already in their portfolios to create efficiencies, causing training or workflow changes.

In a hospital buyout, changes may depend on whether a department is a significant revenue generator for the hospital, Ms. Dooley noted.

PE firms frequently favor higher revenue–generating specialties, such as neurosurgery, cardiology, orthopedics, gastroenterology, and plastic surgery. They closely scrutinize departments said that make less money, such as the emergency department or primary care, Ms. Dooley said. Physicians or teams that don’t fit the firm’s cost-efficiency plans may be terminated or replaced.

On the other hand, Mr. Strode said physicians may see improved electronic health records and collections.

“Some of your overall overhead costs may be reduced, because they’re better at it,” Mr. Strode said. “When you’ve got more scale, the cost per patient, the cost per hour, the cost per procedure, goes down, and the cost that’s applied against your production will go down. As [practices grow], they have more bargaining power with payers and you can potentially get better rates. At least, that’s the promise.”

Analysts note that PE health care acquisitions show no signs of slowing and that it pays for physicians to know what to expect and how to cope if their practice or hospital is acquired. Whether physicians have some control over a buyout or are blindsided by the transition, it’s critical to know what to consider, how workloads might change, and your options for settling in or settling up.

The PE industry has about $2 trillion lined up for potential investments in 2023, said Ms. Dooley.

“PE firms are looking at health care to expend some of this dry powder,” Ms. Dooley continued. “If done correctly, PE firms that are aware of health care regulations, compliance, and patient care issues can ... remove redundant services and improve ... efficiencies, but the bad is when that doesn’t happen, and the quality of care goes down or there are patient safety risks.”
 

How to prepare for and cope with PE partnerships

If your practice is considering a PE partnership, it’s important to explore the terms and conditions and carefully weigh the pros and cons, said Gary Herschman, a Newark, N.J.–based attorney who advises PE-owned physician groups.

“My recommendation is that physicians at a minimum conduct due diligence on all potential strategic options for their groups, and then make an informed decision regarding whether a partnership transaction is right for their group, as it’s not right for every group,” he said.

When Texas cardiologist Rick Snyder, MD, was considering PE partnerships, he spoke with physicians who made similar deals to determine whether they were satisfied years later, he said. In April, Snyder’s practice, HeartPlace, the largest physician-owned cardiology practice in Texas, was acquired by US Heart & Vascular, a practice management platform backed by PE firm Ares Management.

“I called every group that I knew that had done private equity for any meaningful amount of time,” Dr. Snyder said. “For the first year or two, everybody is in the honeymoon period. If the model is going to succeed or break down, it’s not going to be in the first year or two. So I wanted to talk to groups that had done this for a longer amount of time and find out what their pitfalls were. What would they have done differently? Has it been a productive relationship? Did they grow?”

Dr. Snyder, president of the Texas Medical Association, said his practice met with seven or eight firms before choosing one that best met their needs. His group wanted a platform that preserved their clinical autonomy, governance, and culture, he said. They also wanted to ensure they were not entering into a “buy and flip” scenario, but rather a “buy and build” plan.

“Thus, financial capital was not sufficient, they also had to have intellectual capital and relationship capital on their bench,” he said. “When we found the partner that embraced all of these factors as well as a history of buying and long-term building, we pulled the trigger and partnered with Ares and US Heart & Vascular Management. The partner we chose did not offer us the most money. We put a premium on these other criteria.”

“I always tell docs, know the culture of your group and your vision,” he said. “Before you go down that route, ask yourself what you want to accomplish and if it makes sense having a private equity partner to accomplish that vision with.”

For younger physicians or those with little control over buyouts, experts recommend they review their contracts and consider consulting with an attorney to better understand how the deal may affect their earnings and career prospects.

Those who have a much longer career runway need to weigh whether they want to work for a PE-linked practice, Mr. Strode said. For some, it’s time to check when their noncompete agreements end and find a position elsewhere.

Also, physicians should know their rights and the laws in their states regarding the corporate practice of medicine. Statutes vary by state, and knowing the provisions in your state helps doctors recognize their legal rights, learn possible exceptions to the requirements, and know the penalties for violations.

In Michigan, a group of physicians and other health professionals at Ascension St. John has voted to unionize. Doctors hope that the union, which includes advanced practice clinicians, nurse practitioners, and physician assistants, will help improve patient care and protect working conditions for staff, Dr. Wiener said.

She advises physicians who are unhappy after acquisitions to speak up and stick together.

“That’s the biggest thing I think physicians should start doing,” she said. “Support each other and stand up. You are stronger together.”
 

Why is PE so attracted to health care?

PE firms typically buy practices or hospitals, work to make the entities more profitable, and then sell them, with the goal of doubling or tripling their investment over a short period. In general, PE firms aim for annual returns exceeding 20% after 3-7 years.

These firms know that health care is relatively recession-proof, that providers have third-party payers, and that the industry is fragmented and requires more efficiency, Ms. Dooley said.

When PE practice acquisitions started gaining momentum about 12 years ago, traditional hospital-based specialties such as anesthesiology and radiology were prime targets, said Mr. Strode.

At the same time, increasing challenges in private practice, such as declining compensation from payers, pressure to participate in value-based care programs, and rising regional competitors have fueled more physician groups to partner with PE firms, Mr. Herschman noted.

Physicians who partner with PE firms often benefit by having new access to capital to grow their practices, cost savings through group purchasing, and the ability to compete with larger health groups, Mr. Herschman said.

Questions remain, however, about how PE involvement affects health care use and spending. An April 2023 JAMA Viewpoint article called out the lack of oversight and regulation in the health care/PE space, suggesting that a stronger framework for regulation and transparency is needed.

A 2022 study in JAMA Health Forum that examined changes in prices and utilization associated with the PE acquisitions of 578 dermatology, gastroenterology, and ophthalmology physician practices from 2016 to 2020 found that prices increased by an average of 11%, and volume rose by 16%, after acquisition.

“We found that acquisitions were associated with increases in health care spending and utilization, as well as some other patterns of care like potential upcoding,” said Jane M. Zhu, MD, an author of the study and assistant professor at Oregon Health & Science University in Portland.

Another recent study that Dr. Zhu coauthored, published in Health Affairs, found that physician practices acquired by PE firms experience greater staff turnover and rely more heavily on advanced practice professionals than doctors.

“To the extent that that turnover indicates physicians are dissatisfied after private equity comes in, that’s really important to investigate further,” Dr. Zhu said.

PE firms owned 4% of U.S. hospitals in 2021 and 11% of nursing homes, according to a Medicare Payment Advisory Commission (MedPAC) report. The report does not include 2021 data on medical practices but notes that from 2013 to 2016, PE firms acquired at least 2% of physician practices. Estimates of PE deals are probably lower than actual numbers because of the lack of comprehensive information sources, according to the MedPAC report.

French researchers have been working on an innovative vaccine that targets tick microbiota to indirectly reduce the bacterial load within the vector. The results of their study were published in the journal Microbiome.

Ticks are vectors of many harmful pathogens that can cause life-threatening illnesses. Ixodes ricinus (in Europe) and Ixodes scapularis (in Canada and the United States) carry Borrelia, the bacteria that cause Lyme disease. At the moment, there is no vaccine for this disease. But that could all change, thanks to the findings of scientists at the National Research Institute for Agriculture, Food, and Environment (INRAE), in collaboration with the Agency for Food, Environmental, and Occupational Health and Safety and the National Veterinary School of Alfort, France.

“Ticks can transmit a broad variety of pathogens of medical importance, including Borrelia afzelii, the causative agent of Lyme borreliosis in Europe. Tick microbiota is an important factor modulating not only vector physiology, but also the vector competence,” the team reported. They focused their efforts on developing a vaccine that would disturb the tick microbiota and thus reduce Borrelia colonization.

To explore this indirect approach, they injected a harmless strain of Escherichia coli bacteria into mice, which then produced antibodies. Their reasoning was that when a tick bites one of these mice, the antibodies would pass into the arachnid’s microbiota and disturb it, thereby making the tick less harmful. And indeed, the researchers’ work showed that in the ticks that fed on vaccinated mice, levels of Borrelia levels were much lower than in than ticks that fed on unvaccinated mice (see video for an explanation). So, when given to a mouse, this vaccine “protects” the tick against colonization by Borrelia but does not protect the mouse against the disease.

The study has advanced this area of research in two significant ways: It provides new information on the importance of the microbiota when it comes to ticks that are infected with Borrelia, and it suggests an innovative vaccination strategy. Indeed, the results confirm that tick microbiota is essential for the development of Borrelia in the arachnid. As noted in an INRAE press release, “This is a key piece of data that opens the door to one day having an innovative vaccination strategy aimed at perturbing the microbiota of the vector of the Lyme disease agent.”

Dengue, Zika virus, and malaria are also transmitted by a vector – the mosquito. Innovative antimicrobiota vaccines may be able to control these diseases as well.

While oral antibiotics remained the most prescribed systemic treatment for women with acne, spironolactone use continued to grow and became nearly as common as oral antibiotics, results from an analysis of prescribing trends from 2017 through 2020 showed.

Notably, isotretinoin prescribing among men and women decreased slightly during the study period, “which may reflect ongoing administrative burdens associated with iPLEDGE,” study author John S. Barbieri, MD, MBA, of the department of dermatology, at Brigham and Women’s Hospital, Boston, told this news organization.

For the cross-sectional study, which was published online as a research letter in JAMA Dermatology, Dr. Barbieri drew from the Truven Health MarketScan Commercial Claims Database from Jan. 1, 2017, to Dec. 31, 2020, to identify individuals with an encounter for acne, prescriptions for oral tetracycline antibiotics (doxycycline, minocycline), other commonly prescribed oral antibiotics (trimethoprim-sulfamethoxazole, amoxicillin, cephalexin), spironolactone, and isotretinoin. Only drug courses greater than 28 days were included in the analysis, and Dr. Barbieri stratified them according to clinician type (dermatologist, nondermatology physician, and nurse-practitioner or physician assistant). To normalize prescribing rates (to address possible changes in the number of patients treated for acne over time), the number of treatment courses prescribed each year was standardized to the number of encounters for acne with that clinician type during the same calendar year.

The study period included a mean of 1.9 million acne encounters per year.

Dr. Barbieri found that dermatologists prescribed more oral antibiotics per clinician for acne than any other major medical specialty and that oral antibiotics remained frequently prescribed for treating acne by both dermatologists and nondermatologists. “Among oral antibiotics, minocycline and trimethoprim-sulfamethoxazole remain relatively commonly prescribed, despite potential safety concerns and a lack of evidence that they are any more effective than doxycycline,” he said in an interview.

“Patient outcomes could likely be improved by reducing use of minocycline and particularly trimethoprim-sulfamethoxazole given its high risk of serious side effects such as SJS/TEN [Stevens-Johnson syndrome/toxic epidermal necrolysis] and acute respiratory failure,” he added.

Dr. Barbieri noted that there are likely opportunities to consider nonantibiotic alternatives such as hormonal therapy (spironolactone, combined oral contraceptives) and isotretinoin. “There is also a need for continued research to identify nonantibiotic treatment options for patients with acne,” he said.

The analysis revealed that for women with acne prescriptions for spironolactone increased about three- to fourfold during the study period among all clinician types. In 2017, oral antibiotics were prescribed about two- to threefold more often than spironolactone, but by 2020 they were being prescribed at about the same frequency. “Given spironolactone may have similar effectiveness to oral antibiotics in the treatment of acne, this shift in practice has the potential to improve outcomes for patients by reducing the risk of antibiotic-associated complications,” Dr. Barbieri wrote. Still, in 2020, oral antibiotics were still slightly more commonly prescribed than spironolactone by nondermatology physicians and NP or PAs.

In other findings, isotretinoin prescribing decreased slightly among male and female patients during the study period. Among antibiotic prescriptions, prescribing for doxycycline increased at a higher rate than prescribing for minocycline, especially among dermatologists and NPs or PAs.

In the interview, Dr. Barbieri acknowledged certain limitations of the study, including the fact that the dataset “does not allow for evaluation of severity of acne and it is not possible to directly link prescriptions to diagnoses, so some prescriptions might not be for acne and others that are for acne might not have been included.”

Lawrence J. Green, MD, of the department of dermatology at George Washington University, Washington, who was asked to comment on the results, said that, while a course of antibiotic therapy was tied to an office visit in the analysis, the duration of each course of therapy was unclear. It would be interesting to see if antibiotic courses became shorter during the time period analyzed, such as 1-3 months versus 4 or more months, he added, “as this should reduce risks associated with long-term use of oral antibiotics.”

While oral antibiotics remained the most prescribed systemic treatment for women with acne, spironolactone use continued to grow and became nearly as common as oral antibiotics, results from an analysis of prescribing trends from 2017 through 2020 showed.

Notably, isotretinoin prescribing among men and women decreased slightly during the study period, “which may reflect ongoing administrative burdens associated with iPLEDGE,” study author John S. Barbieri, MD, MBA, of the department of dermatology, at Brigham and Women’s Hospital, Boston, told this news organization.

For the cross-sectional study, which was published online as a research letter in JAMA Dermatology, Dr. Barbieri drew from the Truven Health MarketScan Commercial Claims Database from Jan. 1, 2017, to Dec. 31, 2020, to identify individuals with an encounter for acne, prescriptions for oral tetracycline antibiotics (doxycycline, minocycline), other commonly prescribed oral antibiotics (trimethoprim-sulfamethoxazole, amoxicillin, cephalexin), spironolactone, and isotretinoin. Only drug courses greater than 28 days were included in the analysis, and Dr. Barbieri stratified them according to clinician type (dermatologist, nondermatology physician, and nurse-practitioner or physician assistant). To normalize prescribing rates (to address possible changes in the number of patients treated for acne over time), the number of treatment courses prescribed each year was standardized to the number of encounters for acne with that clinician type during the same calendar year.

The study period included a mean of 1.9 million acne encounters per year.

Dr. Barbieri found that dermatologists prescribed more oral antibiotics per clinician for acne than any other major medical specialty and that oral antibiotics remained frequently prescribed for treating acne by both dermatologists and nondermatologists. “Among oral antibiotics, minocycline and trimethoprim-sulfamethoxazole remain relatively commonly prescribed, despite potential safety concerns and a lack of evidence that they are any more effective than doxycycline,” he said in an interview.

“Patient outcomes could likely be improved by reducing use of minocycline and particularly trimethoprim-sulfamethoxazole given its high risk of serious side effects such as SJS/TEN [Stevens-Johnson syndrome/toxic epidermal necrolysis] and acute respiratory failure,” he added.

Dr. Barbieri noted that there are likely opportunities to consider nonantibiotic alternatives such as hormonal therapy (spironolactone, combined oral contraceptives) and isotretinoin. “There is also a need for continued research to identify nonantibiotic treatment options for patients with acne,” he said.

The analysis revealed that for women with acne prescriptions for spironolactone increased about three- to fourfold during the study period among all clinician types. In 2017, oral antibiotics were prescribed about two- to threefold more often than spironolactone, but by 2020 they were being prescribed at about the same frequency. “Given spironolactone may have similar effectiveness to oral antibiotics in the treatment of acne, this shift in practice has the potential to improve outcomes for patients by reducing the risk of antibiotic-associated complications,” Dr. Barbieri wrote. Still, in 2020, oral antibiotics were still slightly more commonly prescribed than spironolactone by nondermatology physicians and NP or PAs.

In other findings, isotretinoin prescribing decreased slightly among male and female patients during the study period. Among antibiotic prescriptions, prescribing for doxycycline increased at a higher rate than prescribing for minocycline, especially among dermatologists and NPs or PAs.

In the interview, Dr. Barbieri acknowledged certain limitations of the study, including the fact that the dataset “does not allow for evaluation of severity of acne and it is not possible to directly link prescriptions to diagnoses, so some prescriptions might not be for acne and others that are for acne might not have been included.”

Hidradenitis suppurativa (HS) is a chronic inflammatory skin condition with lesions that include deep-seated nodules and abscesses, draining tracts, and fibrotic scars, and has been reported to be highly heritable. New findings now suggest that common variants associated with HS, located near the SOX9 and KLF5 genes, may raise the risk of the disease.

A genomewide association study (GWAS) that involved a meta-analysis of data from three large biobanks (UK Biobank, FinnGen, and BioVU) identified one significant locus and two suggestive loci. The researchers were able to replicate the association with HS for two loci near the SOX9 and KLF5 genes in BioVU.

In addition, they also looked at genetic correlations between HS and autoimmune and inflammatory diseases, and results suggested a positive association with inflammatory bowel disease, psoriasis, and type 2 diabetes.

However, while plausible, the variant associations near candidate genes do not prove a causal effect of these variants or genes on disease risk, and further study is needed.

“It’s possible that these genes aren’t the ones affected by the variations we describe, but both are very strong candidates,” said study author Christopher J. Sayed, MD, associate professor of dermatology, University of North Carolina at Chapel Hill. “This improves our understanding of HS as a disease that is likely related to genetic changes that result in dysregulated hair follicle maintenance, inflammation, and wound healing.”

In turn, this will allow clinicians to educate patients about the underlying genetic influences on HS, he explained, as opposed to stigmatizing misconceptions focusing only on weight, smoking, and hygiene.

“Larger studies are underway and will be needed to find variants that may predict things like disease severity and response to treatment, but this is a big first step in the right direction,” Dr. Sayed added.

The study was published online in JAMA Dermatology.
 

Loci identified

GWASs have been limited in HS, and previous research has not identified significant risk loci. In the current study, Dr. Sayed and colleagues sought to identify underlying genes and genetic mechanisms that may underlie pathogenesis in HS.

They performed a GWAS in a cohort of 720 patients who were part of the Hidradenitis Suppurativa Program for Research and Care Excellence (HS ProCARE) at the UNC department of dermatology, and controls from the National Longitudinal Study of Adolescent to Adult Health (Add Health) study, a U.S.-based study following adolescents through adulthood.

The UK Biobank (UKB) is a prospective biobank with about 500,000 individuals aged 40-69 years, and FinnGen collects and analyzes genome and health data from Finnish biobank participants. To increase power to detect associations, a GWAS was performed using participants from the UKB (247 HS cases, 453,048 controls). The HS ProCARE GWAS results were meta-analyzed with UKB, along with data from FinnGen (673 HS cases, 297,544 controls). This three-way meta-analysis revealed one genomewide significant locus and two suggestive loci.

The authors found that the most strongly associated variant, rs10512572 located on chromosome 17, showed the strongest association in FinnGen; at the second locus, the most strongly associated variant was rs17090189 located on chromosome 13 and also showed the strongest association in FinnGen; and at the third locus, the most strongly associated variant, rs5792315, located on chromosome 11, showed the strongest association in HS ProCARE.

Next, they tested the 10 most strongly associated variants at the three loci in the BioVU biobank, which has 290 HS cases, including 189 individuals of European ancestry and 101 individuals of African ancestry, with 64,234 and 12,105 controls, respectively. The locus on chromosome 17 was replicated in BioVU in the same direction of effect, while one variant at the chromosome 13 locus showed nominal evidence of association in the same direction.

In a four-way meta-analysis of BioVU combined with the other three studies, the chromosome locus became more significant and the chromosome 13 locus exceeded the genomewide significance threshold. In contrast, the chromosome 11 locus was not replicated in BioVU (P = .27).

The authors pointed out that variants at these loci are located in keratinocyte regulatory elements near the genes SOX9 and KLF5, which play a role in skin and follicular inflammation, but have not previously been associated with HS pathogenesis.

Finally, they looked to see if there were shared genetic components between HS and autoimmune and inflammatory diseases. A nominally significant genetic correlation was observed between HS and inflammatory bowel disease (P = .04), psoriasis (P = .03), and type 2 diabetes (P = .04), although none reached significance.
 

Different manifestation with genetic variant

In a related study, researchers assessed the prevalence of the NCSTN:c.671_682del variant among individuals with HS in Malta, the island country in the Mediterranean, which has a high prevalence of HS and its associated risk factors, particularly obesity.

Led by Dillon Mintoff, MD, of the department of pathology at the University of Malta, Msida, they conducted a cross-sectional study of 113 adults with HS. In this group, 14 (12.39%) were found to be heterozygous for the NCSTN:c.671_682del variant. Individuals who had this variant were more likely to develop symptoms earlier and to manifest them in atypical skin sites, including the scalp, neck, torso, and antecubital fossae. Additionally, even though their symptoms weren’t more severe than those without the variant, patients with the variant were more likely to require treatment with biologic agents.

Studies move genetics in HS forward

Writing in an accompanying editorial, Atlas Khan, PhD, and Lynn Petukhova, PhD, from Columbia University, New York, noted that both of these HS genetic studies “set a solid foundation for future studies aimed at understanding the biological and clinical relevance of new HS genetic evidence.”

“Each study suggests a series of experiments that will allow us to gain new knowledge about HS,” they wrote, including coming closer to providing patients with a genetic diagnosis.

In addition, evidence from the GWAS paper suggests that with “larger HS GWASs we will be able to better prioritize drug-repurposing studies,” concluded the editorialists. “Both of these goals will help to improve health outcomes for patients with HS and their family members.”

“We were all of us cogs in a great machine which sometimes rolled forward, nobody knew where, sometimes backwards, nobody knew why.” – Ernst Toller

A nice feature of the Apple watch is the stopwatch. With it, I can discreetly click the timer and watch seconds tick away. Tap. There’s one lap. Tap. Two. Tap. That was a quick visit, 6 minutes and 42 seconds. Tap. Under 2 minutes to close the chart. Let’s see if I can beat it. Tap. Tap. What if I moved my Mayo stand over to this side of the room? How about a sign, “All patients must have clothes off if you want a skin exam.” You think ob.gyns. are quick from skin to baby in a stat C-section? You should see how fast I can go from alcohol wipe to Drysol on a biopsy. Seconds. Tick, tick, tap.

Every day I look for ways to go faster. This is not so I can be out the door by 3. Rather, it’s simply to make it through the day without having to log on after we put the kids to bed at night.

Speaking of bedtimes, another nice feature of the Apple watch is the timer. With it, I can set a timer and a lovely chimey alarm will go off. This comes in handy with 3-year-olds. “Sloan, in two minutes we are going to brush your teeth.” Ding. “Sloan, you have one minute to get your pajamas on.” Ding. “Sloanie, I’ll give you 3 more minutes to put the kitties away, then get into bed.” Ding, ding, ding ...

As you can see, using the stopwatch to time a bedtime routine would be demoralizing. If you’ve tried to put a toddler to bed in summer you know. They explore every option to avoid sleeping: one more book (that would make 3), “accidentally” putting their pajamas on backwards, offering to brush their teeth a second time. And once the light is off, “Papa, I have to potty.” No, bedtime routines cannot be standardized. They resist being made efficient.

In contrast, we think of seeing patients as a standardizable process; work to be optimized. This idea that work should be as efficient as possible came from the father of business management, Frederick Taylor. Taylor, a mechanical engineer, observed inefficiencies on the factory floor. His work was seminal in the development of the second industrial revolution. Before then no one had applied scientific rigor to productivity. His book, “The Principles of Scientific Management,” written in 1909, is considered the most influential management book of the 20th century. He was the first to use stopwatches to perform time studies, noting how long each task took with the belief that there was one best way. The worker was an extension of the machine, tuned by management such that he was as efficient as possible.

PublicDomain/commons.wikimedia.org/wiki/File:Ford_assembly_line_-_1913.jpg

A more insidious downside on the drive to efficiency lies in the nature of what we do. We aren’t factory workers punching out widgets, we’re physicians caring for people and people cannot be standardized. In this way, seeing patients is more like putting a toddler to bed than like assembling an iPhone. There will always be by-the-ways, basal cells hiding behind the ear, traffic jams, and bags of products that they want to review. Not sure how to use your fluorouracil? Let’s go over it again. Need to talk more about why you have granuloma annulare? Let me explain. Despite Taylor’s vision, some work simply cannot be optimized. And shouldn’t.

“Where’s my 11:30 patient who checked in half an hour ago?!” I asked my medical assistant. “Oh, she had to go to the bathroom.” Tap.

That was a quick visit, 6 minutes and 42 seconds. Tap. Under 2 minutes to close the chart. Let’s see if I can beat it. Tap. Tap. What if I moved my Mayo stand over to this side of the room? How about a sign, “All patients must have clothes off if you want a skin exam.” You think ob.gyns. are quick from skin to baby in a stat C-section? You should see how fast I can go from alcohol wipe to Drysol on a biopsy. Seconds. Tick, tick, tap.

Every day I look for ways to go faster. This is not so I can be out the door by 3. Rather, it’s simply to make it through the day without having to log on after we put the kids to bed at night.

Speaking of bedtimes, another nice feature of the Apple watch is the timer. With it, I can set a timer and a lovely chimey alarm will go off. This comes in handy with 3-year-olds. “Sloan, in two minutes we are going to brush your teeth.” Ding. “Sloan, you have one minute to get your pajamas on.” Ding. “Sloanie, I’ll give you 3 more minutes to put the kitties away, then get into bed.” Ding, ding, ding ...

As you can see, using the stopwatch to time a bedtime routine would be demoralizing. If you’ve tried to put a toddler to bed in summer you know. They explore every option to avoid sleeping: one more book (that would make 3), “accidentally” putting their pajamas on backwards, offering to brush their teeth a second time. And once the light is off, “Papa, I have to potty.” No, bedtime routines cannot be standardized. They resist being made efficient.

In contrast, we think of seeing patients as a standardizable process; work to be optimized. This idea that work should be as efficient as possible came from the father of business management, Frederick Taylor. Taylor, a mechanical engineer, observed inefficiencies on the factory floor. His work was seminal in the development of the second industrial revolution. Before then no one had applied scientific rigor to productivity. His book, “The Principles of Scientific Management,” written in 1909, is considered the most influential management book of the 20th century. He was the first to use stopwatches to perform time studies, noting how long each task took with the belief that there was one best way. The worker was an extension of the machine, tuned by management such that he was as efficient as possible.

A more insidious downside on the drive to efficiency lies in the nature of what we do. We aren’t factory workers punching out widgets, we’re physicians caring for people and people cannot be standardized. In this way, seeing patients is more like putting a toddler to bed than like assembling an iPhone. There will always be by-the-ways, basal cells hiding behind the ear, traffic jams, and bags of products that they want to review. Not sure how to use your fluorouracil? Let’s go over it again. Need to talk more about why you have granuloma annulare? Let me explain. Despite Taylor’s vision, some work simply cannot be optimized. And shouldn’t.

“Where’s my 11:30 patient who checked in half an hour ago?!” I asked my medical assistant. “Oh, she had to go to the bathroom.” Tap.

Sunday night. Las Vegas. Jason Aldean had just started playing.

My wife and I were at the 2017 Route 91 Harvest Festival with three other couples; two of them were our close friends. We were sitting in the VIP section, a tented area right next to the stage. We started hearing what I was convinced were fireworks.

I’ve been in the Army for 20 some years. I’ve been deployed and shot at multiple times. But these shots were far away. And you don’t expect people to be shooting at you at a concert.

I was on the edge of the VIP area, so I could see around the corner of the tent. I looked up at the Mandalay Bay and saw the muzzle flash in the hotel window. That’s when I knew.

I screamed: “Somebody’s shooting at us! Everybody get down!”

It took a while for people to realize what was going on. When the first couple volleys sprayed into the crowd, nobody understood. But once enough people had been hit and dropped, everyone knew, and it was just mass exodus.

People screamed and ran everywhere. Some of them tried to jump over the front barrier so they could get underneath the stage. Others were trying to pick up loved ones who’d been shot.

The next 15 minutes are a little foggy. I was helping my wife and the people around us to get down. Funny things come back to you afterward. One of my friends was carrying a 16-ounce beer in his hand. Somebody’s shooting at him and he’s walking around with his beer like he’s afraid to put it down. It was so surreal.

We got everybody underneath the tent, and then we just sat there. There would be shooting and then a pause. You’d think it was over. And then there would be more shooting and another pause. It felt like it never was going to stop.

After a short period of time, somebody came in with an official badge, maybe FBI, who knows. They said: “Okay, everybody up. We’ve got to get you out of here.” So, we all got up and headed across the stage. The gate they were taking us to was in full view of the shooter, so it wasn’t very safe.

As I got up, I looked out at the field. Bodies were scattered everywhere. I’m a trauma surgeon by trade. I couldn’t just leave.

I told my two best friends to take my wife with them. My wife lost her mind at that point. She didn’t want me to run out on the field. But I had to. I saw the injured and they needed help. Another buddy and I jumped over the fence and started taking care of people.

The feeling of being out on the field was one of complete frustration. I was in sandals, shorts, and a t-shirt. We had no stretchers, no medical supplies, no nothing. I didn’t have a belt to use as a tourniquet. I didn’t even have a bandage.

Worse: We were seeing high-velocity gunshot wounds that I’ve seen for 20 years in the Army. I know how to take care of them. I know how to fix them. But there wasn’t a single thing I could do.

We had to get people off the field, so we started gathering up as many as we could. We didn’t know if we were going to get shot at again, so we were trying to hide behind things as we ran. Our main objective was just to get people to a place of safety.

A lot of it is a blur. But a few patients stick out in my mind.

A father and son. The father had been shot through the abdomen, exited out through his back. He was in severe pain and couldn’t walk.

A young girl shot in the arm. Her parents carrying her.

A group of people doing CPR on a young lady. She had a gunshot wound to the head or neck. She was obviously dead. But they were still doing chest compressions in the middle of the field. I had to say to them: “She’s dead. You can’t save her. You need to get off the field.” But they wouldn’t stop. We picked her up and took her out while they continued to do CPR.

Later, I realized I knew that woman. She was part of a group of friends that we would see at the festival. I hadn’t recognized her. I also didn’t know that my friend Marco was there. A month or 2 later, we figured out that he was one of the people doing CPR. And I was the guy who came up and said his friend was dead.

Some people were so badly injured we couldn’t lift them. We started tearing apart the fencing used to separate the crowd and slid sections of the barricades under the wounded to carry them. We also carried off a bunch of people who were dead.

We were moving patients to a covered bar area where we thought they would be safer. What we didn’t know was there was an ambulance rally point at the very far end of the field. Unfortunately, we had no idea it was there.

I saw a lot of other first responders out there, people from the fire department, corpsmen from the Navy, medics. I ran into an anesthesia provider and a series of nurses.

When we got everybody off the field, we started moving them into vehicles. People were bringing their trucks up. One guy even stole a truck so he could drive people to the ED. There wasn’t a lot of triage. We were just stacking whoever we could into the backs of these pickups.

I tried to help a nurse taking care of a lady who had been shot in the neck. She was sitting sort of half upright with the patient lying in her arms. When I reached to help her, she said: “You can’t move her.”

“We need to get her to the hospital,” I replied.

“This is the only position that this lady has an airway,” she said. “You’re going to have to move both of us together. If I move at all, she loses her airway.”

So, a group of us managed to slide something underneath and lift them into the back of a truck.

Loading the wounded went on for a while. And then, just like that, everybody was gone.

I walked back out onto this field which not too long ago held 30,000 people. It was as if aliens had just suddenly beamed everyone out.

There was stuff on the ground everywhere – blankets, clothing, single boots, wallets, purses. I walked past a food stand with food still cooking on the grill. There was a beer tap still running. It was the weirdest feeling I’d ever had in my life.

After that, things got a little crazy again. There had been a report of a second shooter, and no one knew if it was real or not. The police started herding a group of us across the street to the Tropicana. We were still trying to take cover as we walked there. We went past a big lion statue in front of one of the casinos. I have a picture from two years earlier of me sitting on the back of that lion. I remember thinking: Now I’m hunkered down behind the same lion hiding from a shooter. Times change.

They brought about 50 of us into a food court, which was closed. They wouldn’t tell us what was going on. And they wouldn’t let us leave. This went on for hours. Meanwhile, I had dropped my cell phone on the field, so my wife couldn’t get hold of me, and later she told me she assumed I’d been shot. I was just hoping that she was safe.

People were huddled together, crying, holding each other. Most were wearing Western concert–going stuff, which for a lot of them wasn’t very much clothing. The hotel eventually brought some blankets.

I was covered in blood. My shirt, shorts, and sandals were soaked. It was running down my legs. I couldn’t find anything to eat or drink. At one point, I sat down at a slot machine, put a hundred dollars in, and started playing slots. I didn’t know what else to do. It didn’t take me very long to lose it all.

Finally, I started looking for a way to get out. I checked all the exits, but there were security and police there. Then I ran into a guy who said he had found a fire exit. When we opened the fire door, there was a big security guard there, and he said: “You can’t leave.”

We said: “Try to stop us. We’re out of here.”

Another thing I’ll always remember – after I broke out of the Tropicana, I was low crawling through the bushes along the Strip toward my hotel. I got a block away and stood up to cross the street. I pushed the crosswalk button and waited. There were no cars, no people. I’ve just broken all the rules, violated police orders, and now I’m standing there waiting for a blinking light to allow me to cross the street!

I made it back to my hotel room around 3:30 or 4:00 in the morning. My wife was hysterical because I hadn’t been answering my cell phone. I came in, and she gave me a big hug, and I got in the shower. Our plane was leaving in a few hours, so we laid down, but didn’t sleep.

As we were getting ready to leave, my wife’s phone rang, and it was my number. A guy at the same hotel had found my phone on the field and called the “in case of emergency” number. So, I got my phone back.

It wasn’t easy to deal with the aftermath. It really affected everybody’s life. To this day, I’m particular about where we sit at concerts. My wife isn’t comfortable if she can’t see an exit. I now have a med bag in my car with tourniquets, pressure dressings, airway masks for CPR.

I’ll never forget that feeling of absolute frustration. That lady without an airway – I could’ve put a trach in her very quickly and made a difference. Were they able to keep her airway? Did she live?

The father and son – did the father make it? I have no idea what happened to any of them. Later, I went through and looked at the pictures of all the people who had died, but I couldn’t recognize anybody.

The hardest part was being there with my wife. I’ve been in places where people are shooting at you, in vehicles that are getting bombed. I’ve always believed that when it’s your time, it’s your time. If I get shot, well, okay, that happens. But if she got shot or my friends ... that would be really tough.

A year later, I gave a talk about it at a conference. I thought I had worked through everything. But all of those feelings, all of that helplessness, that anger, everything came roaring back to the surface again. They asked me how I deal with it, and I said: “Well ... poorly.” I’m the guy who sticks it in a box in the back of his brain, tucks it in and buries it with a bunch of other boxes, and hopes it never comes out again. But every once in a while, it does.

There were all kinds of people out on that field, some with medical training, some without, all determined to help, trying to get those injured people where they needed to be. In retrospect, it does make you feel good. Somebody was shooting at us, but people were still willing to stand up and risk their lives to help others.

We still talk with our friends about what happened that night. Over the years, it’s become less and less. But there’s still a text sent out every year on that day: “Today is the anniversary. Glad we’re all alive. Thanks for being our friends.”

I had to say to them: “She’s dead. You can’t save her. You need to get off the field.” But they wouldn’t stop. We picked her up and took her out while they continued to do CPR.

Later, I realized I knew that woman. She was part of a group of friends that we would see at the festival. I hadn’t recognized her. I also didn’t know that my friend Marco was there. A month or 2 later, we figured out that he was one of the people doing CPR. And I was the guy who came up and said his friend was dead.

Some people were so badly injured we couldn’t lift them. We started tearing apart the fencing used to separate the crowd and slid sections of the barricades under the wounded to carry them. We also carried off a bunch of people who were dead.

We were moving patients to a covered bar area where we thought they would be safer. What we didn’t know was there was an ambulance rally point at the very far end of the field. Unfortunately, we had no idea it was there.

I saw a lot of other first responders out there, people from the fire department, corpsmen from the Navy, medics. I ran into an anesthesia provider and a series of nurses.

When we got everybody off the field, we started moving them into vehicles. People were bringing their trucks up. One guy even stole a truck so he could drive people to the ED. There wasn’t a lot of triage. We were just stacking whoever we could into the backs of these pickups.

I tried to help a nurse taking care of a lady who had been shot in the neck. She was sitting sort of half upright with the patient lying in her arms. When I reached to help her, she said: “You can’t move her.”

“We need to get her to the hospital,” I replied.

“This is the only position that this lady has an airway,” she said. “You’re going to have to move both of us together. If I move at all, she loses her airway.”

So, a group of us managed to slide something underneath and lift them into the back of a truck.

Loading the wounded went on for a while. And then, just like that, everybody was gone.

I walked back out onto this field which not too long ago held 30,000 people. It was as if aliens had just suddenly beamed everyone out.

There was stuff on the ground everywhere – blankets, clothing, single boots, wallets, purses. I walked past a food stand with food still cooking on the grill. There was a beer tap still running. It was the weirdest feeling I’d ever had in my life.

After that, things got a little crazy again. There had been a report of a second shooter, and no one knew if it was real or not. The police started herding a group of us across the street to the Tropicana. We were still trying to take cover as we walked there. We went past a big lion statue in front of one of the casinos. I have a picture from two years earlier of me sitting on the back of that lion. I remember thinking: Now I’m hunkered down behind the same lion hiding from a shooter. Times change.

They brought about 50 of us into a food court, which was closed. They wouldn’t tell us what was going on. And they wouldn’t let us leave. This went on for hours. Meanwhile, I had dropped my cell phone on the field, so my wife couldn’t get hold of me, and later she told me she assumed I’d been shot. I was just hoping that she was safe.

People were huddled together, crying, holding each other. Most were wearing Western concert–going stuff, which for a lot of them wasn’t very much clothing. The hotel eventually brought some blankets.

I was covered in blood. My shirt, shorts, and sandals were soaked. It was running down my legs. I couldn’t find anything to eat or drink. At one point, I sat down at a slot machine, put a hundred dollars in, and started playing slots. I didn’t know what else to do. It didn’t take me very long to lose it all.

Finally, I started looking for a way to get out. I checked all the exits, but there were security and police there. Then I ran into a guy who said he had found a fire exit. When we opened the fire door, there was a big security guard there, and he said: “You can’t leave.”

We said: “Try to stop us. We’re out of here.”

Another thing I’ll always remember – after I broke out of the Tropicana, I was low crawling through the bushes along the Strip toward my hotel. I got a block away and stood up to cross the street. I pushed the crosswalk button and waited. There were no cars, no people. I’ve just broken all the rules, violated police orders, and now I’m standing there waiting for a blinking light to allow me to cross the street!

I made it back to my hotel room around 3:30 or 4:00 in the morning. My wife was hysterical because I hadn’t been answering my cell phone. I came in, and she gave me a big hug, and I got in the shower. Our plane was leaving in a few hours, so we laid down, but didn’t sleep.

As we were getting ready to leave, my wife’s phone rang, and it was my number. A guy at the same hotel had found my phone on the field and called the “in case of emergency” number. So, I got my phone back.

It wasn’t easy to deal with the aftermath. It really affected everybody’s life. To this day, I’m particular about where we sit at concerts. My wife isn’t comfortable if she can’t see an exit. I now have a med bag in my car with tourniquets, pressure dressings, airway masks for CPR.

I’ll never forget that feeling of absolute frustration. That lady without an airway – I could’ve put a trach in her very quickly and made a difference. Were they able to keep her airway? Did she live?

The father and son – did the father make it? I have no idea what happened to any of them. Later, I went through and looked at the pictures of all the people who had died, but I couldn’t recognize anybody.

The hardest part was being there with my wife. I’ve been in places where people are shooting at you, in vehicles that are getting bombed. I’ve always believed that when it’s your time, it’s your time. If I get shot, well, okay, that happens. But if she got shot or my friends ... that would be really tough.

A year later, I gave a talk about it at a conference. I thought I had worked through everything. But all of those feelings, all of that helplessness, that anger, everything came roaring back to the surface again. They asked me how I deal with it, and I said: “Well ... poorly.” I’m the guy who sticks it in a box in the back of his brain, tucks it in and buries it with a bunch of other boxes, and hopes it never comes out again. But every once in a while, it does.

There were all kinds of people out on that field, some with medical training, some without, all determined to help, trying to get those injured people where they needed to be. In retrospect, it does make you feel good. Somebody was shooting at us, but people were still willing to stand up and risk their lives to help others.

We still talk with our friends about what happened that night. Over the years, it’s become less and less. But there’s still a text sent out every year on that day: “Today is the anniversary. Glad we’re all alive. Thanks for being our friends.”

Dermatomyositis is a rare autoimmune condition characterized by muscle inflammation and weakness, and skin findings. The classical presentation includes symmetric proximal muscle weakness and underlying malignancy and is very common in adult patients. The etiology is unknown, however.

Some studies suggest people with certain HLA subtypes are at higher risk, and various infectious and pharmacological triggers are suspected to play a role in the pathogenesis of dermatomyositis. Infectious causes include Coxsackie B, enterovirus, and parvovirus. Drugs such as antineoplastic agents, antibiotics, and NSAIDs have been found to be triggers.

The pathogenesis of dermatomyositis involves immune-mediated damage to muscle capillaries and the endothelium of arterioles. In the typical humoral immune response, complement activation occurs. One mechanism of damage in dermatomyositis occurs when the membrane attack complex formed at the end of the complement process deposits in blood vessels, causing inflammation. B cells, autoantibodies, and interferon overexpression may also play a role in damaging the vasculature and muscle fibers. Hypoxia leads to muscular atrophy, resulting in degeneration and death of the fibers. On muscle biopsy, a perivascular and perimysial inflammatory infiltrate, perifascicular atrophy, and microangiopathy may be present. Skin histology reveals vacuolar changes in the basal layer, a lymphocytic infiltrate, and increased mucin production in the dermis.

On clinical examination, patients will have proximal muscle weakness and a skin rash that may include Gottron’s papules, heliotrope erythema, V-sign, shawl sign, holster sign, scalp erythema, midfacial erythema, and photosensitivity. Scalp erythema in dermatomyositis is highly linked to pruritus, alopecia, and telogen effluvium. Patients may experience small fiber neuropathy in dermatomyositis.

Serologies for this patient, who had previously been diagnosed and treated for dermatomyositis, were significant for a positive ANA 1:2560. Anti-Jo-1 antibody was negative. Her liver function tests, aldolase, creatinine kinase, sedimentation rate, C-reactive protein, and serum protein electrophoresis were normal. Imaging revealed mild chronic interstitial lung disease. A malignancy workup was negative.

Treatment of dermatomyositis involves lifestyle changes and pharmacologic therapy. Because of the intense photosensitivity, patients should be diligent with their sun protection. Methotrexate, azathioprine, and mycophenolate mofetil are considered first-line therapies for dermatomyositis. Therapies such as cyclophosphamide, rituximab, IVIg, and plasmapheresis may also be indicated in severe or refractory cases. Additionally, patients with pulmonary involvement should be given systemic steroids. The side effects of these drugs must be considered in the context of the patient’s demographics, comorbidities and lifestyle.

This case and the photos were submitted by Lucas Shapiro, BS, of Nova Southeastern University College of Osteopathic Medicine, Fort Lauderdale, Fla., and Natalie Y. Nasser, MD, of Kaiser Permanente Riverside Medical Center, Riverside, Calif. The column was edited by Dr. Bilu Martin.

In a case series of 17 men with central centrifugal cicatricial alopecia (CCCA), almost half had a family history of alopecia, most were Black, and the most common symptom was scalp pruritus.

Researchers retrospectively reviewed the medical records of 17 male patients with a clinical diagnosis of CCCA who were seen at University of Pennsylvania outpatient clinics between 2012 and 2022. They excluded patients who had no scalp biopsy or if the scalp biopsy features limited characterization. Temitayo Ogunleye, MD, of the department of dermatology, University of Pennsylvania, Philadelphia, led the study, published in the Journal of the American Academy of Dermatology.

CCCA, a type of scarring alopecia, most often affects women of African descent, and published data on the demographics, clinical findings, and medical histories of CCCA in men are limited, according to the authors.

The average age of the men was 43 years and 88.2% were Black, similar to women with CCCA, who tend to be middle-aged and Black. The four most common symptoms were scalp pruritus (58.8%), lesions (29.4%), pain or tenderness (23.5%), and hair thinning (23.5%). None of the men had type 2 diabetes (considered a possible CCCA risk factor), but 47.1% had a family history of alopecia. The four most common CCCA distributions were classic (47.1%), occipital (17.6%), patchy (11.8%), and posterior vertex (11.8%).

“Larger studies are needed to fully elucidate these relationships and explore etiology in males with CCCA,” the researchers wrote. “Nonetheless, we hope the data will prompt clinicians to assess for CCCA and risk factors in adult males with scarring alopecia.”

Limitations of the study included the retrospective, single-center design, and small sample size.

The researchers reported having no relevant financial relationships.
