TOPLINE:

The time interval between onset of interstitial lung disease (ILD) and diagnosis of anti–melanoma differentiation-associated gene 5 (MDA5) antibody-positive dermatomyositis (DM) “has not been well described,” the authors say.

METHODOLOGY:

• MDA5 antibody-positive DM is a rare DM subtype associated with ILD, which is categorized into rapidly progressive ILD (RPILD) and chronic ILD, with the former having a particularly high mortality rate.
• In this retrospective cohort study using electronic medical records, researchers evaluated 774 patients with DM between 2008 and 2023 to learn more about the time interval between ILD and the time of an MDA5 antibody-positive DM diagnosis, which has not been well described.
• The primary outcome was ILD diagnosis and time in days between documented ILD and MDA5 antibody-positive DM diagnoses.

TAKEAWAY:

• Overall, 14 patients with DM (1.8%) were diagnosed with MDA5 antibody-positive DM in dermatology, rheumatology, or pulmonology departments (nine women and five men; age, 24-77 years; 79% were White and 7% were Black).
• ILD was diagnosed in 9 of the 14 patients (64%); 6 of the 14 (43%) met the criteria for RPILD. Two cases were diagnosed concurrently and two prior to MDA5 antibody-positive DM diagnosis.
• The median time between ILD and MDA5 antibody-positive DM diagnoses was 163 days.
• Gottron papules/sign and midfacial erythema were the most common dermatologic findings, and no association was seen between cutaneous signs and type of ILD.

IN PRACTICE:

“Establishing an accurate timeline between MDA5 antibody-positive DM and ILD can promote urgency among dermatologists to evaluate extracutaneous manifestations in their management of patients with DM for more accurate risk stratification and appropriate treatment,” the authors wrote.

TOPLINE:

Signals for keratoacanthoma and cutaneous squamous cell carcinoma (cSCC) with programmed cell death 1 (PD-1) and programmed cell death ligand 1 (PD-L1) inhibitors were detected in an analysis of adverse events (AEs) reported to the US Food and Drug Administration (FDA).

METHODOLOGY:

• The risk for dermatologic immune-related side effects may be increased with immunologic-modifying drugs.
• To determine if there are significant signals between keratoacanthomas and cSCCs and PD-1/PD-L1 inhibitors, researchers analyzed AEs associated with these agents reported to the FDA’s Adverse Event Reporting System (FAERS) between January 2004 and May 2023.
• Pharmacovigilance signals were identified, and a significant signal was defined as the lower 95% CI of a reporting odds ratio (ROR) greater than one or the lower 95% CI of an information component (IC) greater than 0.

TAKEAWAY:

• Of the 158,000 reports of PD-1/PD-L1 inhibitor use, 43 were in patients who developed a keratoacanthoma (mean age, 77 years; 39% women) and 83 were in patients who developed cSCC (mean age, 71 years; 41% women). Patients aged 60-79 years were most likely to develop keratoacanthomas and cSCC on these treatments.
• A PD-1/PD-L1 inhibitor was listed as the suspect drug in all 43 keratoacanthoma reports and in 70 of 83 cSCC reports (the remaining 13 listed them as the concomitant drug).
• Significant signals were reported for both keratoacanthoma (ROR, 9.7; IC, 1.9) and cSCC (ROR, 3.0; IC, 0.9) with PD-1/PD-L1 inhibitor use.
• Of the reports where this information was available, all 10 cases of PD-1/PD-L1 inhibitor–linked keratoacanthoma and 10 of 17 cases (59%) of PD-1/PD-L1 inhibitor–linked cSCC, resolution was noted following discontinuation or dose reduction of the inhibitor.

IN PRACTICE:

“Given the large number of patients receiving immunotherapy, FAERS recording only 43 patients developing keratoacanthoma and 83 patients developing cSCC highlights that these conditions are relatively rare adverse events,” the authors wrote but added that more studies are needed to confirm these results.

SOURCE:

The study, led by Pushkar Aggarwal, MD, MBA, of the Department of Dermatology, University of Cincinnati, Cincinnati, Ohio, was published online in JAMA Dermatology.

LIMITATIONS:

The data obtained from FAERS did not contain information on all AEs from drugs. In addition, a causal association could not be determined.

DISCLOSURES:

The funding source was not reported. The authors did not report any conflicts of interest.

TOPLINE:

In patients with polycystic ovary syndrome (PCOS), laser and light therapies, alone or in combination with pharmacological agents, improve hirsutism and psychological well-being in women, according to the results of a systematic review.

METHODOLOGY:

• Hirsutism, which affects 70%-80% of women with PCOS, is frequently marginalized as a cosmetic issue by healthcare providers, despite its significant psychological repercussions, including diminished self-esteem, reduced quality of life, and heightened depression.
• The 2023 international evidence-based PCOS guideline considers managing hirsutism a priority in women with PCOS.
• Researchers reviewed six studies (four randomized controlled trials and two cohort studies), which included 423 patients with PCOS who underwent laser or light-based hair reduction therapies, published through 2022.
• The studies evaluated the alexandrite laser, diode laser, and intense pulsed light (IPL) therapy, with and without pharmacological treatments. The main outcomes were hirsutism severity, psychological outcome, and adverse events.

TAKEAWAY:

• Alexandrite laser (wavelength, 755 nm) showed effective hair reduction and improved patient satisfaction (one study); high-fluence treatment yielded better outcomes than low-fluence treatment (one study). Alexandrite laser 755 nm also showed longer hair-free intervals and greater hair reduction than IPL therapy at 650-1000 nm (one study).
• Combined IPL (600 nm) and metformin therapy improved hirsutism and hair count reduction compared with IPL alone, but with more side effects (one study).
• Diode laser treatments (810 nm) with combined oral contraceptives improved hirsutism and related quality of life measures compared with diode laser alone or with metformin (one study).
• Comparing two diode lasers (wavelengths, 810 nm), low-fluence, high repetition laser showed superior hair width reduction and lower pain scores than high fluence, low-repetition laser (one study).

IN PRACTICE:

Laser and light treatments alone or combined with other treatments have demonstrated “encouraging results in reducing hirsutism severity, enhancing psychological well-being, and improving overall quality of life for affected individuals,” the authors wrote, noting that additional high-quality trials evaluating these treatments, which include more patients with different skin tones, are needed.

SOURCE:

The first author of the review is Katrina Tan, MD, Monash Health, Department of Dermatology, Melbourne, Victoria, Australia, and it was published online in JAMA Dermatology.

LIMITATIONS:

Limitations include low certainty of evidence because of the observational nature of some of the studies, the small number of studies, and underrepresentation of darker skin types, limiting generalizability.

DISCLOSURES:

The review is part of an update to the PCOS guideline, which was funded by the Australian National Health and Medical Research Council through various organizations. Several authors reported receiving grants and personal fees outside this work. Dr. Tan was a member of the 2023 PCOS guideline evidence team. Other authors declared no conflicts of interest.

The addition of an angiotensin-converting enzyme (ACE) inhibitor did not decrease risk for chemotherapy-related cardiac damage in patients being treated for breast cancer and non-Hodgkin lymphoma (NHL), a new randomized trial showed.

The results suggested adding an ACE inhibitor doesn’t affect cardiac injury or cardiac function outcomes “and should not be used as a preventative strategy” in these patients, David Austin, MD, consultant cardiologist, Academic Cardiovascular Unit, The James Cook University Hospital, Middlesbrough, England, and chief investigator for the PROACT study, told this news organization.

But while these negative results are disappointing, he said, “we now have a definitive result in a robustly conducted trial that will take the field forward.”

The findings were presented on April 8, 2024, at the American College of Cardiology (ACC) Scientific Session 2024.

Anthracyclines, which are extracted from Streptomyces bacterium, are chemotherapy drugs widely used to treat several types of cancer. Doxorubicin is among the most clinically important anthracyclines.

While extremely effective, anthracyclines can cause irreversible damage to cardiac cells and ultimately impair cardiac function and even cause heart failure, which may only be evident years after exposure. “Cardiac injury is very common in patients treated with high dose anthracyclines,” noted Dr. Austin.

The open-label PROACT study included 111 adult patients, mean age 58 years and predominantly White and women, being treated for breast cancer (62%) or NHL (38%) at National Health Service hospitals in England with high-dose anthracycline-based chemotherapy.

Patients were randomized to standard care (six cycles of high-dose doxorubicin-equivalent anthracycline-based chemotherapy) plus the ACE inhibitor enalapril maleate or standard care alone. The mean chemotherapy dose was 328 mg/m2; any dose greater than 300 is considered high.

The starting dose of enalapril was 2.5 mg twice a day, which was titrated up to a maximum of 10 mg twice a day. The ACE inhibitor was started at least 2 days before chemotherapy began and finished 3 weeks after the last anthracycline dose.

During the study, enalapril was titrated to 20 mg in more than 75% of patients, with the mean dose being 17.7 mg.
 

Myocardial Injury Outcome

The primary outcome was myocardial injury measured by the presence (≥ 14 ng/L) of high sensitivity cardiac troponin T (cTnT) during anthracycline treatment and 1 month after the last dose of anthracycline.

cTnT is highly expressed in cardiomyocytes and has become a preferred biomarker for detecting acute myocardial infarction and other causes of myocardial injury.

Blood sampling for cTnT and cardiac troponin I (cTnI) was performed at baseline, within 72 hours prior to chemotherapy and at trial completion. All patients had negative troponin results at baseline, indicating no heart damage.

A majority of patients experienced elevations in troponin (78% in the enalapril group and 83% in the standard of care group), but there was no statistically significant difference between groups (adjusted odds ratio [OR], 0.65; 95% CI, 0.23-1.78; P = .405).

There was also no significant difference between groups in terms of cTnI, a secondary endpoint. However, the proportion of patients testing positive for cTnI (47% in the enalapril group and 45% in controls) was substantially lower than that for cTnT.
 

Large Discrepancy

The “large discrepancy in the rate of injury” with cTnT “has implications for the clinical interpretation of cardiac biomarkers in routine practice, and we should proceed with caution,” Dr. Austin told this news organization.

The finding has implications because guidelines don’t currently differentiate based on the type of troponin, Dr. Austin said in a press release. “I was surprised by the difference, and I think this raises the question of what troponin we should be using.”

Secondary outcomes focused on cardiac function, measured using echocardiography and included left ventricular global longitudinal strain (LVGLS) and left ventricular ejection fraction (LVEF). These were measured at baseline, 4 weeks after the last anthracycline dose and 1 year after the final chemotherapy.

There was no between-group difference in LVGLS cardiac function (21% for enalapril vs 22% for standard of care; adjusted OR, 0.95; 95% CI, 0.33-2.74; P = .921). This was also true for LVEF (4% for enalapril vs 0% for standard of care group; adjusted OR, 4.89; 95% CI, 0.40-674.62; P = .236).

Asked what the research team plans to do next, Dr. Austin said “the immediate first step” is to continue following PROACT patients. “We know heart failure events and cardiac dysfunction can occur later down the line.”

Due to the challenge of enrolling patients into trials like PROACT, “we should come together as a sort of a broader cardiovascular/oncology academic community to try to understand how we can better recruit patients into these studies,” said Dr. Austin.

“We need to solve that problem before we then go on to maybe examine other potential preventative therapies.”

He doesn’t think an alternative ACE inhibitor would prove beneficial. “We need to look elsewhere for effective therapies in this area.”

He noted these new findings are “broadly consistent” with other trials that investigated angiotensin receptor blockers.
 

Tough Population

Commenting on the study during a media briefing, Anita Deswal, chair, medicine, Department of Cardiology, Division of Internal Medicine, The University of Texas, commended the researchers for managing to enroll patients with cancer as this is “a tough” population to get to agree to being in a clinical trial.

“These patients are often overwhelmed financially, physically, and emotionally with the cancer diagnosis, as well as the cancer therapy and, therefore, to enroll them in something to prevent, maybe, some potential cardiac toxicity down the line, is really hard.”

Past trials investigating neuro-hormonal blockers to prevent cardiotoxicity have been criticized for enrolling patients at “too low risk,” said Dr. Deswal. “But investigators here went that step beyond and enrolled patients who were going to receive higher doses of anthracyclines, so kudos to that.”

And she noted investigators managed to get patients on almost the maximum dose of enalapril. “So, the drug was poised to have an effect — if it was there.”

The negative results may have something to do with endpoints. “Maybe we haven’t quite figured out what are the cutoffs for high sensitivity troponin I that identify patients truly at risk” of developing heart failure in the future.

Commenting on the study for this news organization, Anu Lala, MD, assistant professor of medicine at the Icahn School of Medicine at Mount Sinai, New York City, said the results may come as a surprise to some.

“ACE inhibitors are considered cardioprotective and for this reason are often used prophylactically in patients receiving chemotherapy.”

Dr. Lala agrees troponin may not be the right endpoint. “Another question is whether clinical outcomes should be followed in addition to symptoms or onset of any heart failure symptoms, which may hold greater prognostic significance.”

The study was funded by the National Institute for Health and Care Research.

Blood sampling for cTnT and cardiac troponin I (cTnI) was performed at baseline, within 72 hours prior to chemotherapy and at trial completion. All patients had negative troponin results at baseline, indicating no heart damage.

A majority of patients experienced elevations in troponin (78% in the enalapril group and 83% in the standard of care group), but there was no statistically significant difference between groups (adjusted odds ratio [OR], 0.65; 95% CI, 0.23-1.78; P = .405).

There was also no significant difference between groups in terms of cTnI, a secondary endpoint. However, the proportion of patients testing positive for cTnI (47% in the enalapril group and 45% in controls) was substantially lower than that for cTnT.
 

Large Discrepancy

The “large discrepancy in the rate of injury” with cTnT “has implications for the clinical interpretation of cardiac biomarkers in routine practice, and we should proceed with caution,” Dr. Austin told this news organization.

The finding has implications because guidelines don’t currently differentiate based on the type of troponin, Dr. Austin said in a press release. “I was surprised by the difference, and I think this raises the question of what troponin we should be using.”

Secondary outcomes focused on cardiac function, measured using echocardiography and included left ventricular global longitudinal strain (LVGLS) and left ventricular ejection fraction (LVEF). These were measured at baseline, 4 weeks after the last anthracycline dose and 1 year after the final chemotherapy.

There was no between-group difference in LVGLS cardiac function (21% for enalapril vs 22% for standard of care; adjusted OR, 0.95; 95% CI, 0.33-2.74; P = .921). This was also true for LVEF (4% for enalapril vs 0% for standard of care group; adjusted OR, 4.89; 95% CI, 0.40-674.62; P = .236).

Asked what the research team plans to do next, Dr. Austin said “the immediate first step” is to continue following PROACT patients. “We know heart failure events and cardiac dysfunction can occur later down the line.”

Due to the challenge of enrolling patients into trials like PROACT, “we should come together as a sort of a broader cardiovascular/oncology academic community to try to understand how we can better recruit patients into these studies,” said Dr. Austin.

“We need to solve that problem before we then go on to maybe examine other potential preventative therapies.”

He doesn’t think an alternative ACE inhibitor would prove beneficial. “We need to look elsewhere for effective therapies in this area.”

He noted these new findings are “broadly consistent” with other trials that investigated angiotensin receptor blockers.
 

Tough Population

Commenting on the study during a media briefing, Anita Deswal, chair, medicine, Department of Cardiology, Division of Internal Medicine, The University of Texas, commended the researchers for managing to enroll patients with cancer as this is “a tough” population to get to agree to being in a clinical trial.

“These patients are often overwhelmed financially, physically, and emotionally with the cancer diagnosis, as well as the cancer therapy and, therefore, to enroll them in something to prevent, maybe, some potential cardiac toxicity down the line, is really hard.”

Past trials investigating neuro-hormonal blockers to prevent cardiotoxicity have been criticized for enrolling patients at “too low risk,” said Dr. Deswal. “But investigators here went that step beyond and enrolled patients who were going to receive higher doses of anthracyclines, so kudos to that.”

And she noted investigators managed to get patients on almost the maximum dose of enalapril. “So, the drug was poised to have an effect — if it was there.”

The negative results may have something to do with endpoints. “Maybe we haven’t quite figured out what are the cutoffs for high sensitivity troponin I that identify patients truly at risk” of developing heart failure in the future.

Commenting on the study for this news organization, Anu Lala, MD, assistant professor of medicine at the Icahn School of Medicine at Mount Sinai, New York City, said the results may come as a surprise to some.

“ACE inhibitors are considered cardioprotective and for this reason are often used prophylactically in patients receiving chemotherapy.”

Dr. Lala agrees troponin may not be the right endpoint. “Another question is whether clinical outcomes should be followed in addition to symptoms or onset of any heart failure symptoms, which may hold greater prognostic significance.”

The study was funded by the National Institute for Health and Care Research.

The addition of an angiotensin-converting enzyme (ACE) inhibitor did not decrease risk for chemotherapy-related cardiac damage in patients being treated for breast cancer and non-Hodgkin lymphoma (NHL), a new randomized trial showed.

The results suggested adding an ACE inhibitor doesn’t affect cardiac injury or cardiac function outcomes “and should not be used as a preventative strategy” in these patients, David Austin, MD, consultant cardiologist, Academic Cardiovascular Unit, The James Cook University Hospital, Middlesbrough, England, and chief investigator for the PROACT study, told this news organization.

But while these negative results are disappointing, he said, “we now have a definitive result in a robustly conducted trial that will take the field forward.”

The findings were presented on April 8, 2024, at the American College of Cardiology (ACC) Scientific Session 2024.

Anthracyclines, which are extracted from Streptomyces bacterium, are chemotherapy drugs widely used to treat several types of cancer. Doxorubicin is among the most clinically important anthracyclines.

While extremely effective, anthracyclines can cause irreversible damage to cardiac cells and ultimately impair cardiac function and even cause heart failure, which may only be evident years after exposure. “Cardiac injury is very common in patients treated with high dose anthracyclines,” noted Dr. Austin.

The open-label PROACT study included 111 adult patients, mean age 58 years and predominantly White and women, being treated for breast cancer (62%) or NHL (38%) at National Health Service hospitals in England with high-dose anthracycline-based chemotherapy.

Patients were randomized to standard care (six cycles of high-dose doxorubicin-equivalent anthracycline-based chemotherapy) plus the ACE inhibitor enalapril maleate or standard care alone. The mean chemotherapy dose was 328 mg/m2; any dose greater than 300 is considered high.

The starting dose of enalapril was 2.5 mg twice a day, which was titrated up to a maximum of 10 mg twice a day. The ACE inhibitor was started at least 2 days before chemotherapy began and finished 3 weeks after the last anthracycline dose.

During the study, enalapril was titrated to 20 mg in more than 75% of patients, with the mean dose being 17.7 mg.
 

Myocardial Injury Outcome

The primary outcome was myocardial injury measured by the presence (≥ 14 ng/L) of high sensitivity cardiac troponin T (cTnT) during anthracycline treatment and 1 month after the last dose of anthracycline.

cTnT is highly expressed in cardiomyocytes and has become a preferred biomarker for detecting acute myocardial infarction and other causes of myocardial injury.

DENVER — A new test to detect pathogens related to meningitis, encephalitis, and other neurologic infections is more sensitive than are conventional diagnostics and could vastly improve diagnostic capabilities in the clinic, results of a real-world analysis show.

Metagenomic next-generation sequencing (mNGS) of RNA and DNA from cerebrospinal fluid (CSF) simultaneously tests for a wide range of infectious agents and identifies individual pathogens, including viruses, bacteria, fungi, and parasites. About half of patients with a suspected central nervous system (CNS) infection may go undiagnosed due to a lack of tools that detect rare pathogens. Although mNGS is currently available only in specialized laboratories, expanding access to the diagnostic could address this problem, investigators noted. 

“Our results justify incorporation of CSF mNGS testing as part of the routine diagnostic workup in hospitalized patients who present with potential central nervous system infections,” study investigator Charles Chiu, MD, PhD, professor in the Department of Laboratory Medicine as well as Medicine and Department of Medicine – Infectious Diseases and director of the Clinical Microbiology Laboratory, University of California San Fransisco (UCSF), said at a press conference.

The findings were presented at the 2024 annual meeting of the American Academy of Neurology (AAN).
 

‘Real-World’ Performance

Accurate diagnosis of CNS infections on the basis of CSF, imaging, patient history, and presentation is challenging, the researchers noted. “Roughly 50% of patients who present with a presumed central nervous system infection actually end up without a diagnosis,” Dr. Chiu said.

This is due to the lack of diagnostic tests for rare pathogens and because noninfectious conditions like cancer, autoantibody syndrome, or vasculitis can mimic an infection, he added.

CSF is “very limiting,” Dr. Chiu noted. “We are unable, practically, from a volume perspective, as well as a cost and turnaround time perspective, to be able to send off every possible test for every possible organism.” 

The inability to rapidly pinpoint the cause of an infectious disease like meningitis or encephalitis can cause delays in appropriate treatment.

To assess the “real-world” performance of mNGS, researchers collected 4828 samples from mainly hospitalized patients across the United States and elsewhere from 2016 to 2023. 

Overall, the test detected at least one pathogen in 16.6% of cases. More than 70% were DNA or RNA viruses, followed by bacteria, fungi, and parasites. 
 

High Sensitivity

The technology was also able to detect novel or emerging neurotropic pathogens, including a yellow fever virus responsible for a transfusion-transmitted encephalitis outbreak and Fusarium solani, which caused a fungal meningitis outbreak.

Investigators also conducted a chart review on a subset of 1052 patients at UCSF to compare the performance of CSF nMGS testing with commonly used in-hospital diagnostic tests.

“We showed that as a single test, spinal fluid mNGS has an overall sensitivity of 63%, specificity of 99%, and accuracy of 90%,” said Dr. Chiu.

The sensitivity of mNGS was significantly higher compared with direct-detection testing from CSF (46%); direct-detection testing performed on samples other than CSF, such as blood (15%); and indirect serologic testing looking for antibodies (29%) (P < .001 for all). 

This suggests that mNGS could potentially “detect the hundreds of different pathogens that cause clinically indistinguishable infections,” Dr. Chui said.

mNGS testing is currently confined to large specialized or reference laboratories. For greater access to the test, routine clinical labs or hospital labs would have to implement it, said Dr. Chiu.

“If you can bring the technology to the point of care, directly to the hospital lab that’s running the test, we can produce results that would have a more rapid impact on patients,” he said.
 

Guiding Therapy

Ultimately, he added, the purpose of a diagnostic test is to “generate actionable information that could potentially guide therapy.”

Researchers are now evaluating medical charts of the same subcohort of patients to determine whether the test made a clinical difference.

“We want to know if it had a positive or negative or no clinical impact on the management and treatment of patients,” said Dr. Chiu. “Producing data like this will help us define the role of this test in the future as part of the diagnostic paradigm.”

The researchers are also working on a cost/benefit analysis, and Dr. Chiu said that US Food and Drug Administration approval of the test is needed “to establish a blueprint for reimbursement.”

Commenting on the findings, Jessica Robinson-Papp, MD, professor and vice chair of clinical research, Department of Neurology, Icahn School of Medicine, New York, said that the technology could be useful, especially in developing countries with higher rates of CNS infections. 

“What’s really exciting about it is you can take a very small CSF sample, like 1 mL, and in an unbiased way just screen for all different kinds of pathogens including both DNA and RNA viruses, parasites, bacteria, and fungi, and sort of come up with whether there’s a pathogen there or whether there is no pathogen there,” she said.

However, there’s a chance that this sensitive technique will pick up contaminants, she added. “For example, if there’s a little environmental bacterium either on the skin or in the water used for processing, it can get reads on that.”

The study received support from Delve Bio and the Chan-Zuckerberg Biohub.

Dr. Chiu has received personal compensation for serving on a Scientific Advisory or Data Safety Monitoring Board for Biomeme and has stock in Delve Bio, Poppy Health, Mammoth Biosciences, and BiomeSense and has received intellectual property interests from a discovery or technology relating to healthcare. Dr. Robinson-Papp has no relevant conflicts of interest.

TOPLINE:

An analysis of molecular-targeted cancer drug therapies recently approved in the United States found that fewer than one-third demonstrated substantial clinical benefits at the time of approval.

METHODOLOGY:

• The strength and quality of evidence supporting genome-targeted cancer drug approvals vary. A big reason is the growing number of cancer drug approvals based on surrogate endpoints, such as disease-free and progression-free survival, instead of clinical endpoints, such as overall survival or quality of life. The US Food and Drug Administration (FDA) has also approved genome-targeted cancer drugs based on phase 1 or single-arm trials.
• Given these less rigorous considerations for approval, “the validity and value of the targets and surrogate measures underlying FDA genome-targeted cancer drug approvals are uncertain,” the researchers explained.
• In the current analysis, researchers assessed the validity of the molecular targets as well as the clinical benefits of genome-targeted cancer drugs approved in the United States from 2015 to 2022 based on results from pivotal trials.
• The researchers evaluated the strength of evidence supporting molecular targetability using the European Society for Medical Oncology (ESMO) Scale for Clinical Actionability of Molecular Targets (ESCAT) and the clinical benefit using the ESMO–Magnitude of Clinical Benefit Scale (ESMO-MCBS).
• The authors defined a substantial clinical benefit as an A or B grade for curative intent and a 4 or 5 for noncurative intent. High-benefit genomic-based cancer treatments were defined as those associated with a substantial clinical benefit (ESMO-MCBS) and that qualified as ESCAT category level I-A (a clinical benefit based on prospective randomized data) or I-B (prospective nonrandomized data).

TAKEAWAY:

• The analyses focused on 50 molecular-targeted cancer drugs covering 84 indications. Of which, 45 indications (54%) were approved based on phase 1 or 2 pivotal trials, 45 (54%) were supported by single-arm pivotal trials and the remaining 39 (46%) by randomized trial, and 48 (57%) were approved based on subgroup analyses.
• Among the 84 indications, more than half (55%) of the pivotal trials supporting approval used overall response rate as a primary endpoint, 31% used progression-free survival, and 6% used disease-free survival. Only seven indications (8%) were supported by pivotal trials demonstrating an improvement in overall survival.
• Among the 84 trials, 24 (29%) met the ESMO-MCBS threshold for substantial clinical benefit.
• Overall, when combining all ratings, only 24 of the 84 indications (29%) were considered high-benefit genomic-based cancer treatments.

IN PRACTICE:

“We applied the ESMO-MCBS and ESCAT value frameworks to identify therapies and molecular targets providing high clinical value that should be widely available to patients” and “found that drug indications supported by these characteristics represent a minority of cancer drug approvals in recent years,” the authors said. Using these value frameworks could help payers, governments, and individual patients “prioritize the availability of high-value molecular-targeted therapies.”

SOURCE:

The study, with first author Ariadna Tibau, MD, PhD, Brigham and Women’s Hospital and Harvard Medical School, Boston, was published online in JAMA Oncology.

LIMITATIONS:

The study evaluated only trials that supported regulatory approval and did not include outcomes of postapproval clinical studies, which could lead to changes in ESMO-MCBS grades and ESCAT levels of evidence over time.

DISCLOSURES:

The study was funded by the Kaiser Permanente Institute for Health Policy, Arnold Ventures, and the Commonwealth Fund. The authors had no relevant disclosures.

TOPLINE:

An analysis of molecular-targeted cancer drug therapies recently approved in the United States found that fewer than one-third demonstrated substantial clinical benefits at the time of approval.

METHODOLOGY:

• The strength and quality of evidence supporting genome-targeted cancer drug approvals vary. A big reason is the growing number of cancer drug approvals based on surrogate endpoints, such as disease-free and progression-free survival, instead of clinical endpoints, such as overall survival or quality of life. The US Food and Drug Administration (FDA) has also approved genome-targeted cancer drugs based on phase 1 or single-arm trials.
• Given these less rigorous considerations for approval, “the validity and value of the targets and surrogate measures underlying FDA genome-targeted cancer drug approvals are uncertain,” the researchers explained.
• In the current analysis, researchers assessed the validity of the molecular targets as well as the clinical benefits of genome-targeted cancer drugs approved in the United States from 2015 to 2022 based on results from pivotal trials.
• The researchers evaluated the strength of evidence supporting molecular targetability using the European Society for Medical Oncology (ESMO) Scale for Clinical Actionability of Molecular Targets (ESCAT) and the clinical benefit using the ESMO–Magnitude of Clinical Benefit Scale (ESMO-MCBS).
• The authors defined a substantial clinical benefit as an A or B grade for curative intent and a 4 or 5 for noncurative intent. High-benefit genomic-based cancer treatments were defined as those associated with a substantial clinical benefit (ESMO-MCBS) and that qualified as ESCAT category level I-A (a clinical benefit based on prospective randomized data) or I-B (prospective nonrandomized data).

TAKEAWAY:

• The analyses focused on 50 molecular-targeted cancer drugs covering 84 indications. Of which, 45 indications (54%) were approved based on phase 1 or 2 pivotal trials, 45 (54%) were supported by single-arm pivotal trials and the remaining 39 (46%) by randomized trial, and 48 (57%) were approved based on subgroup analyses.
• Among the 84 indications, more than half (55%) of the pivotal trials supporting approval used overall response rate as a primary endpoint, 31% used progression-free survival, and 6% used disease-free survival. Only seven indications (8%) were supported by pivotal trials demonstrating an improvement in overall survival.
• Among the 84 trials, 24 (29%) met the ESMO-MCBS threshold for substantial clinical benefit.
• Overall, when combining all ratings, only 24 of the 84 indications (29%) were considered high-benefit genomic-based cancer treatments.

BALTIMORE — Patients who have complications after dermatologic cosmetic procedures are prone to high rates of a host of mental health issues, ranging from anxiety disorder and depression to body dysmorphic disorder (BDD) and posttraumatic stress disorder (PTSD), according to a survey-based study of patients with dermatology-related complications. 

The study used an anonymous 40-question survey circulated to a Facebook cosmetic complication support group. Seventy-one of 100 individuals completed the questionnaire, reporting significantly higher rates of mental health issues after their complications than before. Results were presented at the annual conference of the American Society for Laser Medicine and Surgery (ASLMS). Almost all the survey respondents (99%) were female, with 61% aged 25-44 years and 34% aged 45-64 years.

Taryn Murray, MD

“Cosmetic procedures have increased over the past decade, with procedures being increasingly performed by an evolving variety of providers,” the study’s lead author, Taryn Murray, MD, a dermatologist at Cleveland Clinic, Cleveland, Ohio, told this news organization. “Appropriate patient assessment and counseling and proper procedure technique are important for obtaining safe and effective results. Complications may not only impact patients physically but can also be harmful to their mental health.”
 

Rise in Mental Health Issues

The study found that before respondents had the treatment that led to their complications, 16% reported a history of generalized anxiety disorder, 15% a history of depression, and 1% a history of either BDD or PTSD. Following the complication, 50% reported a positive depression screening, 63% a positive BDD Questionnaire – Dermatology Version, and 63% a positive Primary Care PTSD screen, Dr. Murray said. “Almost half of respondents (46%) reported thinking about their complication for more than 3 hours a day,” she said in presenting the results. 

Dr. Murray said the idea for the study grew out of her experience as a fellow working with Paul Friedman, MD, at the Dermatology and Laser Surgery Center at University of Texas Health in Houston.

“We were seeing a lot of complications,” Dr. Murray said in an interview. “Some of these were local. Some of these patients were flying in from out-of-state looking for help with the complication, and we could see what a mental and emotional burden this put on these patients. They were routinely in the office in tears saying it was interfering with their daily life, it was interfering with their job, saying they were going to lose their job, all because they were so distressed over what was happening to them.”

Yet, the research into psychological distress in patients with dermatologic complications is minimal, Dr. Murray added. “We think that body dysmorphic disorder is prevalent for patients seeking dermatology or plastic surgery services, but I don’t think either of the specialties do a great job in screening people for that when they come for treatment, so I think a lot of it goes undiagnosed. There’s been a trend looking at more at complications lately, but there’s been a gap in the literature.”

The treatments the patients in the survey had were microneedling with radiofrequency (29%), laser (24%), ultrasound for skin tightening (11%), radiofrequency for skin tightening (11%), microneedling (4%), chemical peel (3%), body contouring/sculpting (1%), and “other” (17%).

The study found that the largest share of procedures, 47%, were done by an esthetician/laser technician, followed by a nondermatologist physician (17%), a board-certified dermatologist (14%), an advanced practice provider (12%), and “other” (10%).

Self-reported complications included scarring (38%), hyperpigmentation (26%), erythema (24%), burn (23%), blisters (11%), and hypopigmentation (3%); 71% characterized their complications as “other,” and one respondent reported multiple complications.

“Respondents said they were satisfied with the previous cosmetic care they received,” Dr. Murray said during her presentation at the meeting. “And there was a consensus among the respondents that they did not feel adequately counseled on the risks of the procedure and that it did not meet their expectations and anticipated outcome.”
 

Take-Home Lesson

The lesson here is that practitioners who perform cosmetic procedures should be well-versed in the task and potential complications, Dr. Murray said in the interview. “If you’re going to be doing a procedure, make sure you know the proper techniques, the proper endpoints, and how to treat if you’re to have a complication,” she said. “If you don’t know how to treat a complication from the device, then you should think twice about using it.”

She also suggested screening patients for potentially undiagnosed mental health disorders. “It can play a role in the initial consultation and potentially any after-care they might need if there is a complication,” she said. “We may not have the adequate tools at this time to know how to best handle these patients and these scenarios, but hopefully my abstract will shed a little more light on it.”

She said she hopes her findings lead to more research in the future.

Asked to comment on the study, Jennifer Lin, MD, assistant professor of dermatology at Brigham and Women’s Hospital and Dana Farber Cancer Institute in Boston, Massachusetts, said one finding of the study stood out to her. “ I was very surprised from her dataset that patients think about it more than 3 hours a day,” she told this news organization. “That’s really significant. We talk about the side effects, but we don’t necessarily talk about the burden of how long the recovery will be or the psychological burden of potentially dealing with it.”

She noted that “there’s a bit of movement” toward developing guidelines for laser treatments, which would address the risk of complications. “That’s the goal: To have better guidelines to avoid these complications in the first place,” Dr. Lin said.

The study findings also point to a need for “premonitoring” individuals before procedures, she added. “We talked about patient selection and make sure someone doesn’t have body dysmorphic disorder, but we don’t formally screen for it,” she said. “We don’t our train our residents to screen for it. And I think doing more pre- and post-testing of how people are affected by laser treatment is going to become more important.”

Dr. Murray disclosed relationships with R2 Technologies. Dr. Lin had no relationships to disclose.

Combining D-limonene, a naturally occurring terpene in cannabis, with delta-9-tetrahydrocannabinol (THC), the primary psychoactive component in cannabis, may mitigate THC-induced anxiety, new data from a small study suggested.

Participants who inhaled vaporized D-limonene and THC reported significantly greater decreases in anxiogenic effects than did people who received either component alone or a placebo. Reductions were greater as the dose of the D-limonene was increased.

Investigators noted that the findings could have implications for the use of medicinal or recreational cannabis, which has increased in recent years due to state legalization efforts.

“People use cannabis to help reduce anxiety, depression, and posttraumatic stress disorder, but since THC levels vary widely, if a person overshoots their tolerance of THC, cannabis can induce anxiety rather than relieve it,” senior investigator Ryan Vandrey, PhD, professor of psychiatry and behavioral sciences, Johns Hopkins School of Medicine, Baltimore, said in a news release.

“Our study demonstrates that D-limonene can modulate the effects of THC in a meaningful way and make THC more tolerable to people using it for both therapeutic and non-therapeutic purposes,” he added.

The study was published online in Drug and Alcohol Dependence.
 

Entourage Theory

Cannabis legalization has opened the door to an increased range of medicinal and nonmedicinal uses, but its benefits can be limited by the anxiety and panic some people experience with its use, investigators noted.

Many cannabis plants have been bred to contain higher concentrations of THC, with some dispensaries selling cannabis with more than 20%-30% THC. The plants often include cannabidiol, “minor” cannabinoids, and terpenes, such as D-limonene.

Prior studies pointed to THC as the cause of acute behavioral and psychoactive effects some cannabis users experience. However, a new, untested theory, the “cannabis entourage effect theory,” suggested other components in cannabis, including D-limonene, may contribute to the anxiogenic symptoms.

“We were motivated by scientific publications that hypothesized D-limonene can attenuate the acute anxiogenic effects of cannabis, but for which empirical data did not exist,” Dr. Vandrey said.

Investigators designed a small double-blind, within-subjects crossover study of 20 healthy adults (median age, 26 years; 50% men). About half of participants were Caucasian/non-Hispanic, 30% African American/non-Hispanic, 10% Caucasian/Hispanic, and 10% Asian/non-Hispanic.

All participants completed nine outpatient drug administration sessions, during which they inhaled vaporized D-limonene alone (1 or 5 mg), THC alone (15 or 30 mg), the same doses of THC and D-limonene together, or placebo.

Primary outcomes included subjective drug effects, measured with the Drug Effect Questionnaire (DEQ) and the 20-item state subscale of the State-Trait Anxiety Inventory (STAI-S). Investigators also measured cognitive/psychomotor performance with the Digit Symbol Substitution Task (DSST) and the Paced Serial Addition Task.

Vital signs such as heart rate, systolic blood pressure (SBP), diastolic blood pressure (DBP), and plasma D-limonene and THC concentrations were also tracked.

Participants’ responses were measured at baseline and then an additional nine times after initial exposure over the course of each 6-hour test session. Blood and urine samples were collected from participants before, during, and after each session.
 

First Evidence

There were no significant differences in outcomes between the D-limonene alone and placebo groups.

Receipt of 15- and 30-mg doses of THC alone was associated with subjective reports of acute cannabis exposure, including cognitive and physiological effects.

A treatment effect was observed for “anxious/nervous” (P < .01), “paranoid” (P < .01), and “heart racing” (P < .0001).

In planned comparisons, ratings of anxiety-like subjective effects qualitatively decreased as D-limonene dose increased, and concurrent administration of 30-mg THC plus 15-mg D-limonene significantly reduced ratings of “anxious/nervous” and “paranoid” on the DEQ compared to 30 mg of THC alone (P < .05).

Findings were similar on the composite score of the STAI-S, and although planned comparisons did not reach the threshold for statistical significance, reductions in anxiety approached significance in the THC plus D-limonene group compared with the THC alone condition (P = .08). The combination group also reported significantly lower subjective ratings of unpleasant drug effects than the THC alone group (P = .03).

In particular, a main effect of treatment was found for the anxious/nervous category on the DEQ (P < .01), as well as the “paranoid” (P < .01) and heart racing (P < .0001) categories.

On the other hand, ratings of anxious/nervous and paranoid categories were significantly lower in the 30-mg THC plus 15-mg D-limonene vs the 30-mg THC alone condition (P < .05, for all).

As for cognition, following drug administration, a significant main effect of treatment was observed for the DSST (P < .05), but no significant differences between THC and THC plus D-limonene combination conditions or between D-limonene alone and placebo were detected.

There were no differences within each THC dose and between D-limonene alone versus placebo conditions. Moreover, there were no main effects of treatment found for SBP or DBP.

The combination condition produced significantly greater concentrations of THC than the THC alone condition (P < .05).

“This study provides the first evidence that there are chemical constituents found naturally in the cannabis plant that can reduce some of the adverse effects of using delta-9-THC,” Dr. Vandrey said.

Although the exact mechanism by which vaporized D-limonene counters the anxiogenic effects of THC is unclear, “our best guess is that D-limonene is producing an anxiolytic effect on its own that is not mediated by cannabinoid receptors,” Dr. Vandrey said.
 

Significant Impact

Commenting on the research, Joshua Lile, PhD, professor, Department of Behavioral Science, University of Kentucky College of Medicine, Lexington, noted that the study seems to be the first of its kind to study the influence of terpene on THC response.

The research “makes a significant impact on our field,” and is “among the few controlled clinical studies that have demonstrated interactions between THC and other cannabis constituents, supporting the validity of the ‘entourage’ effect,” said Dr. Lile, who was not involved with the current research.

“This work is particularly important, given the unfounded claims sometimes made by the cannabis industry regarding the effects of different cannabis products,” he added.

Also commenting on the study, Ziva Cooper, PhD, professor and director of the UCLA Center for Cannabis and Cannabinoids, University of California Los Angeles, said the findings “have direct implications for improving the safety of cannabis, whether it’s being used for medical or nonmedical purposes, especially in people and patients who do not have experience with cannabis, a group that is at high risk for experiencing anxiety after using cannabis.”

In addition, “an important aspect to this study is that the effects of limonene in reducing anxiety attributed to delta-9-THC were observed at higher concentrations (or doses) than those usually present in the plant,” Dr. Copper said. “This calls for further investigation into new cannabis formulations specifically designed to leverage the potential protective effects of the terpene.”

In planned comparisons, ratings of anxiety-like subjective effects qualitatively decreased as D-limonene dose increased, and concurrent administration of 30-mg THC plus 15-mg D-limonene significantly reduced ratings of “anxious/nervous” and “paranoid” on the DEQ compared to 30 mg of THC alone (P < .05).

Findings were similar on the composite score of the STAI-S, and although planned comparisons did not reach the threshold for statistical significance, reductions in anxiety approached significance in the THC plus D-limonene group compared with the THC alone condition (P = .08). The combination group also reported significantly lower subjective ratings of unpleasant drug effects than the THC alone group (P = .03).

In particular, a main effect of treatment was found for the anxious/nervous category on the DEQ (P < .01), as well as the “paranoid” (P < .01) and heart racing (P < .0001) categories.

On the other hand, ratings of anxious/nervous and paranoid categories were significantly lower in the 30-mg THC plus 15-mg D-limonene vs the 30-mg THC alone condition (P < .05, for all).

As for cognition, following drug administration, a significant main effect of treatment was observed for the DSST (P < .05), but no significant differences between THC and THC plus D-limonene combination conditions or between D-limonene alone and placebo were detected.

There were no differences within each THC dose and between D-limonene alone versus placebo conditions. Moreover, there were no main effects of treatment found for SBP or DBP.

The combination condition produced significantly greater concentrations of THC than the THC alone condition (P < .05).

“This study provides the first evidence that there are chemical constituents found naturally in the cannabis plant that can reduce some of the adverse effects of using delta-9-THC,” Dr. Vandrey said.

Although the exact mechanism by which vaporized D-limonene counters the anxiogenic effects of THC is unclear, “our best guess is that D-limonene is producing an anxiolytic effect on its own that is not mediated by cannabinoid receptors,” Dr. Vandrey said.
 

Significant Impact

Commenting on the research, Joshua Lile, PhD, professor, Department of Behavioral Science, University of Kentucky College of Medicine, Lexington, noted that the study seems to be the first of its kind to study the influence of terpene on THC response.

The research “makes a significant impact on our field,” and is “among the few controlled clinical studies that have demonstrated interactions between THC and other cannabis constituents, supporting the validity of the ‘entourage’ effect,” said Dr. Lile, who was not involved with the current research.

“This work is particularly important, given the unfounded claims sometimes made by the cannabis industry regarding the effects of different cannabis products,” he added.

Also commenting on the study, Ziva Cooper, PhD, professor and director of the UCLA Center for Cannabis and Cannabinoids, University of California Los Angeles, said the findings “have direct implications for improving the safety of cannabis, whether it’s being used for medical or nonmedical purposes, especially in people and patients who do not have experience with cannabis, a group that is at high risk for experiencing anxiety after using cannabis.”

In addition, “an important aspect to this study is that the effects of limonene in reducing anxiety attributed to delta-9-THC were observed at higher concentrations (or doses) than those usually present in the plant,” Dr. Copper said. “This calls for further investigation into new cannabis formulations specifically designed to leverage the potential protective effects of the terpene.”

Combining D-limonene, a naturally occurring terpene in cannabis, with delta-9-tetrahydrocannabinol (THC), the primary psychoactive component in cannabis, may mitigate THC-induced anxiety, new data from a small study suggested.

Participants who inhaled vaporized D-limonene and THC reported significantly greater decreases in anxiogenic effects than did people who received either component alone or a placebo. Reductions were greater as the dose of the D-limonene was increased.

Investigators noted that the findings could have implications for the use of medicinal or recreational cannabis, which has increased in recent years due to state legalization efforts.

“People use cannabis to help reduce anxiety, depression, and posttraumatic stress disorder, but since THC levels vary widely, if a person overshoots their tolerance of THC, cannabis can induce anxiety rather than relieve it,” senior investigator Ryan Vandrey, PhD, professor of psychiatry and behavioral sciences, Johns Hopkins School of Medicine, Baltimore, said in a news release.

“Our study demonstrates that D-limonene can modulate the effects of THC in a meaningful way and make THC more tolerable to people using it for both therapeutic and non-therapeutic purposes,” he added.

The study was published online in Drug and Alcohol Dependence.
 

Entourage Theory

Cannabis legalization has opened the door to an increased range of medicinal and nonmedicinal uses, but its benefits can be limited by the anxiety and panic some people experience with its use, investigators noted.

Many cannabis plants have been bred to contain higher concentrations of THC, with some dispensaries selling cannabis with more than 20%-30% THC. The plants often include cannabidiol, “minor” cannabinoids, and terpenes, such as D-limonene.

Prior studies pointed to THC as the cause of acute behavioral and psychoactive effects some cannabis users experience. However, a new, untested theory, the “cannabis entourage effect theory,” suggested other components in cannabis, including D-limonene, may contribute to the anxiogenic symptoms.

“We were motivated by scientific publications that hypothesized D-limonene can attenuate the acute anxiogenic effects of cannabis, but for which empirical data did not exist,” Dr. Vandrey said.

Investigators designed a small double-blind, within-subjects crossover study of 20 healthy adults (median age, 26 years; 50% men). About half of participants were Caucasian/non-Hispanic, 30% African American/non-Hispanic, 10% Caucasian/Hispanic, and 10% Asian/non-Hispanic.

All participants completed nine outpatient drug administration sessions, during which they inhaled vaporized D-limonene alone (1 or 5 mg), THC alone (15 or 30 mg), the same doses of THC and D-limonene together, or placebo.

Primary outcomes included subjective drug effects, measured with the Drug Effect Questionnaire (DEQ) and the 20-item state subscale of the State-Trait Anxiety Inventory (STAI-S). Investigators also measured cognitive/psychomotor performance with the Digit Symbol Substitution Task (DSST) and the Paced Serial Addition Task.

Vital signs such as heart rate, systolic blood pressure (SBP), diastolic blood pressure (DBP), and plasma D-limonene and THC concentrations were also tracked.

Participants’ responses were measured at baseline and then an additional nine times after initial exposure over the course of each 6-hour test session. Blood and urine samples were collected from participants before, during, and after each session.
 

First Evidence

There were no significant differences in outcomes between the D-limonene alone and placebo groups.

Receipt of 15- and 30-mg doses of THC alone was associated with subjective reports of acute cannabis exposure, including cognitive and physiological effects.

A treatment effect was observed for “anxious/nervous” (P < .01), “paranoid” (P < .01), and “heart racing” (P < .0001).

In planned comparisons, ratings of anxiety-like subjective effects qualitatively decreased as D-limonene dose increased, and concurrent administration of 30-mg THC plus 15-mg D-limonene significantly reduced ratings of “anxious/nervous” and “paranoid” on the DEQ compared to 30 mg of THC alone (P < .05).

Findings were similar on the composite score of the STAI-S, and although planned comparisons did not reach the threshold for statistical significance, reductions in anxiety approached significance in the THC plus D-limonene group compared with the THC alone condition (P = .08). The combination group also reported significantly lower subjective ratings of unpleasant drug effects than the THC alone group (P = .03).

In particular, a main effect of treatment was found for the anxious/nervous category on the DEQ (P < .01), as well as the “paranoid” (P < .01) and heart racing (P < .0001) categories.

On the other hand, ratings of anxious/nervous and paranoid categories were significantly lower in the 30-mg THC plus 15-mg D-limonene vs the 30-mg THC alone condition (P < .05, for all).

As for cognition, following drug administration, a significant main effect of treatment was observed for the DSST (P < .05), but no significant differences between THC and THC plus D-limonene combination conditions or between D-limonene alone and placebo were detected.

There were no differences within each THC dose and between D-limonene alone versus placebo conditions. Moreover, there were no main effects of treatment found for SBP or DBP.

The combination condition produced significantly greater concentrations of THC than the THC alone condition (P < .05).

Recent cases of botulism-like illness following neurotoxin injections in nonmedical settings have prompted the American Society for Dermatologic Surgery Association (ASDSA) to call on states to increase oversight of medical care in all settings, including medical spas.

In a press release issued on April 12, the ASDSA referenced investigations in Illinois and Tennessee in which suspected counterfeit neurotoxins were associated with individuals’ symptoms resembling botulism, including several that required hospitalization. These cases “emphasize the patient safety risks associated with receiving medical procedures in unlicensed, unapproved settings without proper oversight of medical care,” the release adds.

The cases also “highlight the need for increased public protection measures, like the recommendations in the ASDSA’s “Medical Spa Safety Act” to ensure patients’ safety,” according to the press release, which notes the increasing demand for facial fillers and neuromodulators in the United States.

Enforcement is needed to ensure that all patients receive US Food and Drug Administration (FDA)-approved products “and not counterfeit products or unsafe treatments,” ASDSA president Seth L. Matarasso, MD, who practices dermatology in San Francisco, said in the press release. “Lack of regulation and enforcement has enabled many to offer medical procedures for cosmetic purposes outside of their training and expertise,” he said.

Key Takeaways

All clinicians need to understand that aesthetic procedures are medical procedures and require a level of due diligence in patient evaluation and care before, during, and after the procedure, Pooja Sodha, MD, director of the Center for Laser and Cosmetic Dermatology at George Washington University, Washington, said in an interview.

Dr. Sodha

“FDA-approved medications should only be offered, and these should be obtained through well-defined sources to ensure their safety and purity,” she said.

However, some challenges to the enforcement of safety in medical spa settings persist, Dr. Sodha told this news organization. “To my knowledge, state and federal policies providing clear and up-to-date safety and legal guidelines for aesthetic procedures performed at medical spas by registered nurses, nurse practitioners, physician assistants, and physicians are limited, and in our current medical care structure, national oversight is challenging,” she said.

A pretreatment checklist assessment, she suggested, could be helpful “to ensure patient safety and help to standardize clinical practice in nonmedical settings.”

Other challenges include a lack of clear guidelines for aesthetic providers regarding initial assessment examinations, postprocedure follow-up, and evaluation for any future medical treatment, as well as “continued ambiguity on the exact meaning of physician oversight for those sites that delegate aesthetic services and appropriate and clear guidelines on what procedures require a licensed provider to perform versus oversee the treatment,” she said.
 

Additional Guidance, Actions Needed

As for additional guidance or actions, “we may be migrating towards a system that designates and assigns clearer licenses and authorizations to perform these services and care for patients,” said Dr. Sodha. A licensing process would entail academic understanding of anatomy, pharmacology, and tissue interactions, as well as practical hands-on training that emphasizes the importance of the preprocedure consultation and postprocedure follow-up and care, she said. “Experience in caring for the unintended outcomes is vital to delivering the best care we can,” she added.

D. Sodha had no financial conflicts to disclose.

Depression is a serious issue. I want to say that off the top, because nothing below is intended to minimize it.

But does everyone need to be tested for it?

A lot of general practices test for it with every patient and every visit. After all, mandates say you have to or you’ll get penalized a few bucks. Since no one wants to leave any money on the table in the razor-thin margins of running a medical practice, they ask these questions (I don’t blame them for that).

I can see where this might be useful, but does it really do much? Or is it just a mandatory waste of time?

Good question.

A recent review by the American College of Physicians found it was mostly a waste of time (which surprises no one). Only one of the eight measures involved in depression screening (suicide risk assessment) turned out to be useful. So, basically, 88% of the time spent on these questions contributed absolutely nothing of clinical relevance.

Of course, this isn’t unique to family medicine. Every time I see a Medicare or Medicare Advantage patient I have to document whether they’ve had flu and pneumonia vaccines. While there are occasional cases where asking about recent vaccines is critical to the history, for most it’s not. But I do it so I don’t get penalized, even though the answer changes nothing. It’s not like I give vaccines in my practice.

A fair number of people come to me for hospital follow-ups, so I go into the system and review the chart. The notes inevitably contain questions of sexual activity, fear of violence, fear of domestic abuse, food security, recent travel patterns, and so on. Some of them are useful in certain situations, but not in all, or even most. All they do is increase the length of the note until anything of relevance is obscured, and allow someone in coding to check the boxes to raise the billing level. Realistically, the ER staff involved probably didn’t ask any of them, and just clicked “no.”

Once this probably seemed like a good idea, but clearly most of it is now a waste of time. These “quality measures” have turned the art of taking a good history into a session of mouse and box clicking.

Does that really improve care?
