Conference Coverage

Most younger women diagnosed with nonmetastatic breast cancer will succeed if they attempt to become pregnant after treatment, according to new research.

The findings, presented May 23 in advance of the annual meeting of the American Society of Clinical Oncology (ASCO) represent the most comprehensive look to date at fertility outcomes following treatment for women diagnosed with breast cancer before age 40 (Abstract 1518).

Kimia Sorouri, MD, a research fellow at the Dana-Farber Cancer Center in Boston, Massachusetts, and her colleagues, looked at data from the Young Women’s Breast Cancer study, a multicenter longitudinal cohort study, for 1213 U.S. and Canadian women (74% non-Hispanic white) who were diagnosed with stages 0-III breast cancer between 2006 and 2016. None of the included patients had metastatic disease, prior hysterectomy, or prior oophorectomy at diagnosis.

During a median 11 years of follow up, 197 of the women reported attempting pregnancy. Of these, 73% reported becoming pregnant, and 65% delivered a live infant a median 4 years after cancer diagnosis. The median age at diagnosis was 32 years, and 28% opted for egg or embryo freezing to preserve fertility. Importantly, 68% received chemotherapy, which can impair fertility, with only a small percentage undergoing ovarian suppression during chemotherapy treatment.

Key predictors of pregnancy or live birth in this study were “financial comfort,” a self-reported measure defined as having money left over to spend after bills are paid (odds ratio [OR], 2.04; 95% CI 1.01-4.12; P = .047); younger age at the time of diagnosis; and undergoing fertility preservation interventions at diagnosis (OR, 2.78; 95% CI 1.29-6.00; P = .009). Chemotherapy and other treatment factors were not seen to be associated with pregnancy or birth outcomes.

“Current research that informs our understanding of the impact of breast cancer treatment on pregnancy and live birth rates is fairly limited,” Dr. Sorouri said during an online press conference announcing the findings. Quality data on fertility outcomes has been limited to studies in certain subgroups, such as women with estrogen receptor–positive breast cancers, she noted, while other studies “have short-term follow-up and critically lack prospective assessment of attempt at conception.”

The new findings show, Dr. Sorouri said, “that in this modern cohort with a heightened awareness of fertility, access to fertility preservation can help to mitigate a portion of the damage from chemotherapy and other agents. Importantly, this highlights the need for increased accessibility of fertility preservation services for women newly diagnosed with breast cancer who are interested in a future pregnancy.”

Commenting on Dr. Sorouri and colleagues’ findings, Julie Gralow, MD, a breast cancer researcher and ASCO’s chief medical officer, stressed that, while younger age at diagnosis and financial comfort were two factors outside the scope of clinical oncology practice, “we can impact fertility preservation prior to treatment.”

She called it “critical” that every patient be informed of the impact of a breast cancer diagnosis and treatment on future fertility, and that all young patients interested in future fertility be offered fertility preservation prior to beginning treatment.

Ann Partridge, MD, of Dana-Farber, said in an interview that the findings reflected a decades’ long change in approach. “Twenty years ago when we first started this cohort, people would tell women ‘you can’t get pregnant. It’s too dangerous. You won’t be able to.’ And some indeed aren’t able to, but the majority who are attempting are succeeding, especially if they preserve their eggs or embryos. So even if chemo puts you into menopause or made you subfertile, if you’ve preserved eggs or embryos, we now can mitigate that distressing effect that many cancer patients have suffered from historically. That’s the good news here.”

Nonetheless, Dr. Partridge, an oncologist and the last author of the study, noted, the results reflected success only for women actively attempting pregnancy. “Remember, we’re not including the people who didn’t attempt. There may be some who went into menopause who never banked eggs or embryos, and may never have tried because they went to a doctor who told them they’re not fertile.” Further, she said, not all insurances cover in vitro fertilization for women who have had breast cancer.

The fact that financial comfort was correlated with reproductive success, Dr. Partridge said, speaks to broader issues about access. “It may not be all about insurers. It may be to have the ability, to have the time, the education and the wherewithal to do this right — and about being with doctors who talk about it.”

Dr. Sorouri and colleagues’ study was sponsored by the Breast Cancer Research Foundation and Susan G. Komen. Several co-authors disclosed receiving speaking and/or consulting fees from pharmaceutical companies, and one reported being an employee of GlaxoSmithKline. Dr. Sorouri reported no industry funding, while Dr. Partridge reported research funding from Novartis.

PARIS — While anaphylaxis requires immediate adrenaline administration through autoinjection, the use of this treatment is not optimal. Therefore, the development of new adrenaline formulations (such as for intranasal, sublingual, and transcutaneous routes) aims to facilitate the drug’s use and reduce persistent delays in administration by patients and caregivers. An overview of the research was presented at the 19th French-speaking Congress of Allergology.

Anaphylaxis is a severe and potentially fatal immediate hypersensitivity reaction with highly variable and dynamic clinical presentations. It requires prompt recognition for immediate treatment with intramuscular (IM) adrenaline (at the anterolateral aspect of the mid-thigh).

One might think that this reflex is acquired, but in France, while the number of prescribed adrenaline autoinjection (AAI) devices has been increasing for a decade, reaching 965,944 units in 2022, this first-line treatment is underused. Anapen (150, 300, and 500 µg), EpiPen (150 and 300 µg), Jext (150 µg and 300 µg), and Emerade (150, 300, and 500 µg) are the four products marketed in France in 2024.

“Only 17.3% of individuals presenting to the emergency department in the Lorraine region used it in 2015,” said Catherine Neukirch, MD, a pneumologist at Hôpital Bichat–Claude Bernard in Paris, France, with rates of 11.3% for children and 20.3% for adults.
 

Anaphylaxis Incidence Increasing

Approximately 0.3% (95% CI, 0.1-0.5) of the population will experience an anaphylaxis episode in their lifetime. Incidence in Europe, across all causes, is estimated between 1.5 and 7.9 cases per 100,000 inhabitants per year. Although anaphylaxis is on the rise, its associated mortality remains low, ranging between 0.05 and 0.51 per million per year for drugs, between 0.03 and 0.32 per million per year for foods, and between 0.09 and 0.13 per million per year for hymenopteran venoms.

Data from the European Anaphylaxis Registry indicate that anaphylaxis manifests rapidly after allergen exposure: 55% of cases occur within 10 minutes and 80% within 30 minutes. In addition, a biphasic reaction, which can occur up to 72 hours after exposure, is observed in < 5% of cases.

While a delay in adrenaline use is associated with risk for increased morbidity and mortality, AAI significantly reduces error rates compared with manual treatments involving ampoules, needles, and syringes. It also reduces the associated panic risks. However, there are multiple barriers to adrenaline use. The clinical symptoms of anaphylaxis may be misleading, especially if it occurs without cutaneous and urticarial manifestations but with only acute bronchospasm. It may present as isolated laryngeal edema without digestive involvement, hypotension, or other respiratory problems.

Other limitations to adrenaline use include technical difficulties and the possibility of incorrect administration, the need for appropriate needle sizes for patients with obesity, needle phobia, potential adverse effects of adrenaline injections, failure to carry two autoinjectors, constraints related to storage and bulky transport, as well as the need for training and practice.

“These factors contribute to underuse of adrenaline by patients and caregivers,” said Dr. Neukirch, which results in delays in necessary administration.
 

Adrenaline Treatment Criteria?

An analysis published in 2023 based on pharmacovigilance data from 30 regional French centers from 1984 to 2022 included 42 reported cases (average age, 33 years; 26% children) of reactions to AAI, which probably is an underestimate. About 40% of AAI uses occurred during anaphylaxis. The remaining 60% were triggered outside of reactions. The main reasons were accidental injections, mainly in the fingers, and cases of not triggering the autoinjector, underlining the importance of patient education.

In 2015, the European Medicines Agency required pharmacological studies for injectable adrenaline on healthy volunteers. These studies include ultrasound measurements of bolus injection, pharmacokinetics (ie, absorption, distribution, metabolism, and excretion), and pharmacodynamics (ie, the effect of the drug and the mechanism of action in the body), with precise evaluation of cardiovascular effects (eg, systolic and diastolic blood pressures and heart rate).

Among the information collected with the different products, ultrasound studies have shown a different localization of the adrenaline bolus (ie, in muscle in patients with normal BMI and mostly in adipose tissue in patients with BMI indicating overweight and obesity). The consequences of this finding are still unknown.

In a study with 500 µg Anapen, women with overweight or obesity showed different pharmacokinetic or pharmacodynamic profiles from those in men with normal weight, with an increase in the area under the curve (0-240 min) and marked changes in the heart rate time curve.

IM administration of 0.5 mg produces rapid pharmacokinetic effects in patients with normal weight, overweight, or obesity, with a delay for the second peak in the latter case. This delay perhaps results from initial local vasoconstriction due to adrenaline.

The early peak plasma concentration occurs at 5-10 minutes for AAI, with a faster speed for Anapen and EpiPen.

Moreover, needle size is not the most important factor. Rather, it is the strength and speed of injection, which can vary depending on the AAI.

Also, the optimal plasma concentration of adrenaline to treat anaphylaxis is not known; studies cannot be conducted during anaphylaxis. In terms of pharmacokinetics, a small series discovered that increased skin or muscle thickness delays the absorption of EpiPen AAI.
 

Intranasal Adrenaline

To facilitate rapid adrenaline use and convince reluctant patients to carry and use adrenaline, intranasal, sublingual, or transcutaneous forms are under development.

Three intranasal forms of adrenaline are already well advanced, including Neffy from ARS Pharma, epinephrine sprays from Bryn Pharma and Hikma, and Oxero from Oragoo, which contains dry powder.

A comparison of intranasal adrenaline Neffy and AAI shows that the former has satisfactory pharmacokinetic and pharmacodynamic effects.

In a phase 1 randomized crossover study of 42 healthy adults comparing the pharmacokinetic effects of Neffy adrenaline (2 mg) and EpiPen (0.3 mg), as well as IM epinephrine 0.3 mg, several observations were made. For a single dose, the maximum concentration (Cmax) of Neffy was lower than that of EpiPen.

However, with repeated doses administered 10 minutes apart, the Cmax of Neffy was higher than that of EpiPen. At this stage, pharmacodynamic responses to intranasal products are at least comparable with those of approved injectable products.

A comparison of the pharmacodynamic effects, such as systolic and diastolic blood pressures and heart rate, of Neffy adrenaline and AAI concluded that the profile of Neffy is comparable with that of EpiPen and superior to that of IM epinephrine.

In patients with a history of allergic rhinitis, adrenaline Cmax appears to be increased, while time to peak plasma concentration (Tmax) is reduced. Low blood pressure does not prevent Neffy absorption. Neffy is currently under review by the American and European health authorities.

Intranasal absorption of dry powder adrenaline appears to be faster than that of EpiPen, thus offering a clinical advantage in the short therapeutic window for anaphylaxis treatment.

In an open-label trial conducted on 12 adults with seasonal allergic rhinitis without asthma, the pharmacokinetics, pharmacodynamics, and safety of adrenaline were compared between FMXIN002 (1.6 and 3.2 mg), which was administered intranasally with or without nasal allergen challenge, and IM EpiPen 0.3 mg. Pharmacokinetics varied by patient. Nevertheless, nasal FMXIN002 had a shorter Tmax, a doubled Cmax after the allergen challenge peak, and a higher area under the curve in the 8 hours following administration compared with EpiPen. Pharmacodynamic effects comparable with those of EpiPen were noted at 15 minutes to 4 hours after administration. The tolerance was good, with mild and local side effects. The powder seems to deposit slightly better in the nasal cavity. It remains stable for 6 months at a temperature of 40 °C and relative humidity of 75% and for 2 years at a temperature of 25 °C and relative humidity of 60%.
 

Sublingual Adrenaline Film

AQST-109 is a sublingual film that is intended to allow rapid administration of epinephrine 1, which is a prodrug of adrenaline. The product is the size of a postage stamp, weighs < 30 g, and dissolves on contact with the tongue.

The EPIPHAST II study was a phase 1, multiperiod, crossover study conducted on 24 healthy adults (age, 24-49 years) who were randomly assigned to receive either 12 or 0.3 mg of AQST-109  of manual IM adrenaline in the first two periods. All participants received 0.3 mg of EpiPen in the last period.

EpiPen 0.3 mg resulted in a higher Cmax than AQST-109 12 mg. AQST-109 12 mg had the fastest median Tmax of 12 minutes. The areas under the curve of AQST-109 12 mg fell between those of EpiPen 0.3 mg and manual IM adrenaline 0.3 mg.

Early increases in systolic blood pressure, diastolic blood pressure, and heart rate were observed with AQST-109 12 mg. Changes were more pronounced with AQST-109 12 mg despite a higher Cmax with EpiPen 0.3 mg.

Part 3 of the EPIPHAST study evaluated the impact of food exposure (ie, a peanut butter sandwich) on the pharmacokinetics of AQST-109 12 mg in 24 healthy adults. Oral food residues did not significantly affect pharmacodynamic parameters, and no treatment-related adverse events were reported.

Researchers concluded that AQST-109 12 mg absorption would not be altered by “real” situations if used during meals. “These results suggest that the sublingual adrenaline film could be promising in real situations,” said Dr. Neukirch, especially in cases of food allergy with recent ingestion of the allergenic food.
 

Transcutaneous Adrenaline

A transcutaneous form of adrenaline that uses the Zeneo device developed by Crossject, a company based in Dijon, France, comes in the form of an AAI that requires no needle. This project, funded by the European Union, uses a gas generator to propel the drug at very high speed through the skin in 50 milliseconds. This method allows for extended drug storage.

Dr. Neukirch reported financial relationships with Viatris, Stallergènes, ALK, Astrazeneca, Sanofi, GSK, and Novartis.

Early increases in systolic blood pressure, diastolic blood pressure, and heart rate were observed with AQST-109 12 mg. Changes were more pronounced with AQST-109 12 mg despite a higher Cmax with EpiPen 0.3 mg.

Part 3 of the EPIPHAST study evaluated the impact of food exposure (ie, a peanut butter sandwich) on the pharmacokinetics of AQST-109 12 mg in 24 healthy adults. Oral food residues did not significantly affect pharmacodynamic parameters, and no treatment-related adverse events were reported.

Researchers concluded that AQST-109 12 mg absorption would not be altered by “real” situations if used during meals. “These results suggest that the sublingual adrenaline film could be promising in real situations,” said Dr. Neukirch, especially in cases of food allergy with recent ingestion of the allergenic food.
 

Transcutaneous Adrenaline

A transcutaneous form of adrenaline that uses the Zeneo device developed by Crossject, a company based in Dijon, France, comes in the form of an AAI that requires no needle. This project, funded by the European Union, uses a gas generator to propel the drug at very high speed through the skin in 50 milliseconds. This method allows for extended drug storage.

Dr. Neukirch reported financial relationships with Viatris, Stallergènes, ALK, Astrazeneca, Sanofi, GSK, and Novartis.

PARIS — While anaphylaxis requires immediate adrenaline administration through autoinjection, the use of this treatment is not optimal. Therefore, the development of new adrenaline formulations (such as for intranasal, sublingual, and transcutaneous routes) aims to facilitate the drug’s use and reduce persistent delays in administration by patients and caregivers. An overview of the research was presented at the 19th French-speaking Congress of Allergology.

Anaphylaxis is a severe and potentially fatal immediate hypersensitivity reaction with highly variable and dynamic clinical presentations. It requires prompt recognition for immediate treatment with intramuscular (IM) adrenaline (at the anterolateral aspect of the mid-thigh).

One might think that this reflex is acquired, but in France, while the number of prescribed adrenaline autoinjection (AAI) devices has been increasing for a decade, reaching 965,944 units in 2022, this first-line treatment is underused. Anapen (150, 300, and 500 µg), EpiPen (150 and 300 µg), Jext (150 µg and 300 µg), and Emerade (150, 300, and 500 µg) are the four products marketed in France in 2024.

“Only 17.3% of individuals presenting to the emergency department in the Lorraine region used it in 2015,” said Catherine Neukirch, MD, a pneumologist at Hôpital Bichat–Claude Bernard in Paris, France, with rates of 11.3% for children and 20.3% for adults.
 

Anaphylaxis Incidence Increasing

Approximately 0.3% (95% CI, 0.1-0.5) of the population will experience an anaphylaxis episode in their lifetime. Incidence in Europe, across all causes, is estimated between 1.5 and 7.9 cases per 100,000 inhabitants per year. Although anaphylaxis is on the rise, its associated mortality remains low, ranging between 0.05 and 0.51 per million per year for drugs, between 0.03 and 0.32 per million per year for foods, and between 0.09 and 0.13 per million per year for hymenopteran venoms.

Data from the European Anaphylaxis Registry indicate that anaphylaxis manifests rapidly after allergen exposure: 55% of cases occur within 10 minutes and 80% within 30 minutes. In addition, a biphasic reaction, which can occur up to 72 hours after exposure, is observed in < 5% of cases.

While a delay in adrenaline use is associated with risk for increased morbidity and mortality, AAI significantly reduces error rates compared with manual treatments involving ampoules, needles, and syringes. It also reduces the associated panic risks. However, there are multiple barriers to adrenaline use. The clinical symptoms of anaphylaxis may be misleading, especially if it occurs without cutaneous and urticarial manifestations but with only acute bronchospasm. It may present as isolated laryngeal edema without digestive involvement, hypotension, or other respiratory problems.

Other limitations to adrenaline use include technical difficulties and the possibility of incorrect administration, the need for appropriate needle sizes for patients with obesity, needle phobia, potential adverse effects of adrenaline injections, failure to carry two autoinjectors, constraints related to storage and bulky transport, as well as the need for training and practice.

“These factors contribute to underuse of adrenaline by patients and caregivers,” said Dr. Neukirch, which results in delays in necessary administration.
 

Adrenaline Treatment Criteria?

An analysis published in 2023 based on pharmacovigilance data from 30 regional French centers from 1984 to 2022 included 42 reported cases (average age, 33 years; 26% children) of reactions to AAI, which probably is an underestimate. About 40% of AAI uses occurred during anaphylaxis. The remaining 60% were triggered outside of reactions. The main reasons were accidental injections, mainly in the fingers, and cases of not triggering the autoinjector, underlining the importance of patient education.

In 2015, the European Medicines Agency required pharmacological studies for injectable adrenaline on healthy volunteers. These studies include ultrasound measurements of bolus injection, pharmacokinetics (ie, absorption, distribution, metabolism, and excretion), and pharmacodynamics (ie, the effect of the drug and the mechanism of action in the body), with precise evaluation of cardiovascular effects (eg, systolic and diastolic blood pressures and heart rate).

Among the information collected with the different products, ultrasound studies have shown a different localization of the adrenaline bolus (ie, in muscle in patients with normal BMI and mostly in adipose tissue in patients with BMI indicating overweight and obesity). The consequences of this finding are still unknown.

In a study with 500 µg Anapen, women with overweight or obesity showed different pharmacokinetic or pharmacodynamic profiles from those in men with normal weight, with an increase in the area under the curve (0-240 min) and marked changes in the heart rate time curve.

IM administration of 0.5 mg produces rapid pharmacokinetic effects in patients with normal weight, overweight, or obesity, with a delay for the second peak in the latter case. This delay perhaps results from initial local vasoconstriction due to adrenaline.

The early peak plasma concentration occurs at 5-10 minutes for AAI, with a faster speed for Anapen and EpiPen.

Moreover, needle size is not the most important factor. Rather, it is the strength and speed of injection, which can vary depending on the AAI.

Also, the optimal plasma concentration of adrenaline to treat anaphylaxis is not known; studies cannot be conducted during anaphylaxis. In terms of pharmacokinetics, a small series discovered that increased skin or muscle thickness delays the absorption of EpiPen AAI.
 

Intranasal Adrenaline

To facilitate rapid adrenaline use and convince reluctant patients to carry and use adrenaline, intranasal, sublingual, or transcutaneous forms are under development.

Three intranasal forms of adrenaline are already well advanced, including Neffy from ARS Pharma, epinephrine sprays from Bryn Pharma and Hikma, and Oxero from Oragoo, which contains dry powder.

A comparison of intranasal adrenaline Neffy and AAI shows that the former has satisfactory pharmacokinetic and pharmacodynamic effects.

In a phase 1 randomized crossover study of 42 healthy adults comparing the pharmacokinetic effects of Neffy adrenaline (2 mg) and EpiPen (0.3 mg), as well as IM epinephrine 0.3 mg, several observations were made. For a single dose, the maximum concentration (Cmax) of Neffy was lower than that of EpiPen.

However, with repeated doses administered 10 minutes apart, the Cmax of Neffy was higher than that of EpiPen. At this stage, pharmacodynamic responses to intranasal products are at least comparable with those of approved injectable products.

A comparison of the pharmacodynamic effects, such as systolic and diastolic blood pressures and heart rate, of Neffy adrenaline and AAI concluded that the profile of Neffy is comparable with that of EpiPen and superior to that of IM epinephrine.

In patients with a history of allergic rhinitis, adrenaline Cmax appears to be increased, while time to peak plasma concentration (Tmax) is reduced. Low blood pressure does not prevent Neffy absorption. Neffy is currently under review by the American and European health authorities.

Intranasal absorption of dry powder adrenaline appears to be faster than that of EpiPen, thus offering a clinical advantage in the short therapeutic window for anaphylaxis treatment.

In an open-label trial conducted on 12 adults with seasonal allergic rhinitis without asthma, the pharmacokinetics, pharmacodynamics, and safety of adrenaline were compared between FMXIN002 (1.6 and 3.2 mg), which was administered intranasally with or without nasal allergen challenge, and IM EpiPen 0.3 mg. Pharmacokinetics varied by patient. Nevertheless, nasal FMXIN002 had a shorter Tmax, a doubled Cmax after the allergen challenge peak, and a higher area under the curve in the 8 hours following administration compared with EpiPen. Pharmacodynamic effects comparable with those of EpiPen were noted at 15 minutes to 4 hours after administration. The tolerance was good, with mild and local side effects. The powder seems to deposit slightly better in the nasal cavity. It remains stable for 6 months at a temperature of 40 °C and relative humidity of 75% and for 2 years at a temperature of 25 °C and relative humidity of 60%.
 

Sublingual Adrenaline Film

AQST-109 is a sublingual film that is intended to allow rapid administration of epinephrine 1, which is a prodrug of adrenaline. The product is the size of a postage stamp, weighs < 30 g, and dissolves on contact with the tongue.

The EPIPHAST II study was a phase 1, multiperiod, crossover study conducted on 24 healthy adults (age, 24-49 years) who were randomly assigned to receive either 12 or 0.3 mg of AQST-109  of manual IM adrenaline in the first two periods. All participants received 0.3 mg of EpiPen in the last period.

EpiPen 0.3 mg resulted in a higher Cmax than AQST-109 12 mg. AQST-109 12 mg had the fastest median Tmax of 12 minutes. The areas under the curve of AQST-109 12 mg fell between those of EpiPen 0.3 mg and manual IM adrenaline 0.3 mg.

Early increases in systolic blood pressure, diastolic blood pressure, and heart rate were observed with AQST-109 12 mg. Changes were more pronounced with AQST-109 12 mg despite a higher Cmax with EpiPen 0.3 mg.

Part 3 of the EPIPHAST study evaluated the impact of food exposure (ie, a peanut butter sandwich) on the pharmacokinetics of AQST-109 12 mg in 24 healthy adults. Oral food residues did not significantly affect pharmacodynamic parameters, and no treatment-related adverse events were reported.

BOSTON — Primary care clinicians caring for patients with intellectual and developmental disabilities often recommend guardianship, a responsibility with life-altering implications. 

But only approximately 30% of primary care residency programs in the United States provide training  on how to assess the ability of patients with disabilities to make decisions for themselves, and much of this training is optional, according to a recent study cited during a workshop at the 2024 annual meeting of the Society of General Internal Medicine.

Assessing the capacity of patients with disabilities involves navigating a maze of legal, ethical, and clinical considerations, according to Mary Thomas, MD, MPH, a clinical fellow in geriatrics at Yale University School of Medicine in New Haven, Connecticut, who co-moderated the workshop.

Guardianship, while sometimes necessary, can be overly restrictive and diminish patient autonomy, she said. The legal process — ultimately decided through the courts — gives a guardian permission to manage medical care and make decisions for someone who cannot make or communicate those decisions themselves.

Clinicians can assess patients through an evaluation of functional capacity, which allows them to observe a patient’s demeanor and administer a cognition test. Alternatives such as supported decision-making may be less restrictive and can better serve patients, she said. Supported decision-making allows for a person with disabilities to receive assistance from a supporter who can help a patient process medical conditions and treatment needs. The supporter helps empower capable patients to decide on their own.

Some states have introduced legislation that would legally recognize supported decision-making as a less restrictive alternative to guardianship or conservatorship, in which a court-appointed individual manages all aspects of a person’s life. 

Sara Mixter, MD, MPH, an assistant professor of medicine and pediatrics at the Johns Hopkins University School of Medicine in Baltimore and a co-moderator of the workshop, called the use of inclusive language in patient communication the “first step toward fostering an environment where patients feel respected and understood.”

Inclusive conversations can include person-first language and using words such as “caregiver” rather than “caretaker.” 

Dr. Thomas and Dr. Mixter also called for the directors of residency programs to provide more training on disabilities. They cited a 2023 survey of directors, many of whom said that educational boards do not require training in disability-specific care and that experts in the care of people with disabilities are few and far between.

“Education and awareness are key to overcoming the challenges we face,” Dr. Thomas said. “Improving our training programs means we can ensure that all patients receive the care and respect they deserve.”

Dr. Thomas and Dr. Mixter report no relevant disclosures.

BOSTON — Online patient portals have shifted patient expectations of how quickly clinicians respond and provide timely care, which can lead to burnout. But asynchronous care can, in some cases, be compensated and increase physician productivity and enhance patient care, according to experts who led a workshop at the Society of General Internal Medicine (SGIM) 2024 Annual Meeting.

Patient portal visits have increased in popularity and use since the COVID-19 pandemic. For primary care clinicians especially, the amount of time spent and the span of requests, from messages with new health concerns to requests for prescription refills, can be daunting.

“Understanding the nuances of these relationships is pivotal in navigating the evolution toward asynchronous care,” said Jennifer Schmidt, MD, an assistant professor of medicine at the Washington University School of Medicine in St. Louis, who co-moderated the workshop.

But patient portals can give clinicians another tool to deliver care beyond conventional office visits or telemedicine appointments, Dr. Schmidt said.

Clinicians can bill insurance if their response to a patient question takes longer than 5 minutes to compose. Responses to messages related to scheduling appointments, refilling prescriptions, or visit follow-ups are not billable.

Some participants at the session said their employers do not have policies that allow compensation for their work in patient portals. Others said their health systems have reported that patients who use portals more frequently have higher satisfaction scores.

Asynchronous care holds promise for extending care beyond traditional constraints, according to Stephen Fuest, MD, an assistant professor of internal medicine at the University of Colorado Anschutz Medical Campus in Aurora, Colorado, and a co-moderator of the workshop.

“By capitalizing on our experiences in designing and implementing systems for portal communication, we can find ways to optimize productivity and alleviate burnout,” Dr. Fuest said.

Dr. Fuest noted that while compensation rates for virtual care are lower than those for in-person, the lack of geographical barriers and time constraints allow clinicians to care for more patients. Asynchronous care also can limit losing patients to follow-up.

WASHINGTON — In contrast with a previous study that found glucagon-like peptide 1 (GLP-1) receptor agonists associated with an increased risk for acute pancreatitis and bowel obstruction, a new retrospective study found no significant link to these complications. The new data did, however, reinforce an association between GLP-1s and gastroparesis and biliary disease, specifically gallstones.

One of the big differences from the previous study, published in JAMA in October 2023 by Sodhi and colleagues , is that the current research was able to account for initial body mass index (BMI), said Benjamin Liu, MD, a resident in internal medicine at Case Western Reserve University School of Medicine, Cleveland, Ohio.

This is important, he explained in his presentation (abstract 1074) at the annual Digestive Disease Week^® 2024, because obesity on its own is associated with an increased risk for some of these gastrointestinal (GI) outcomes.

“They did an excellent study,” Dr. Liu said. “But their platform did not allow them to match participants for BMI.”

Another distinction between the two studies is that the JAMA study excluded people who had diabetes 90 days before or 30 days following the start of GLP-1 therapy.

Instead, Dr. Liu said, he and colleague Gengqing Song, MD, “just made it simple” and excluded anyone with diabetes or an A1c ≥ 6.5.

We didn’t want participants with diabetes because “we were looking at GLP-1s for weight loss,” Dr. Liu explained.

Although some clinical trials have already assessed adverse events of these medications, “clinical trials are not always a perfect representation of the real world,” Dr. Liu said in an interview. “So, it’s important to do real-world studies to see just what actually goes on.”
 

Reassessing GI Complications 

In the current study, the researchers identified 105,793 patients from the TriNetX healthcare database taking a GLP-1, either semaglutide or liraglutide, for weight loss and 8794 patients taking 8 mg naltrexone/90 mg bupropion. After propensity matching, including for BMI, there were 8792 patients in each group.

They were identified in the database between 2011 and 2023. Researchers noted their first-ever occurrence of acute pancreatitis, bowel obstruction, gastroparesis, or biliary disease during the study period.

Participants had a BMI ≥ 30 kg/m². In addition to BMI, propensity score matching included demographics, alcohol use, smoking, hyperlipidemia, and abdominal surgery. A second analysis specifically did not match participants for BMI.

The researchers found no significant association between GLP-1s and acute pancreatitis (adjusted hazard ratio [HR], 1.19; 95% CI, 0.66-2.14).

The labeling for semaglutide and liraglutide warns about an increased risk for acute pancreatitis, “but real-world studies and clinical trials are increasingly suggesting there is no increased risk,” Dr. Liu said.

They also did not find a significant association between GLP-1s and bowel obstruction (HR, 1.30; 95% CI, 0.69-2.18).

Despite the current findings, more research — especially prospective data — is needed to confirm pancreatitis as well as other GI risks like bowel obstruction potentially associated with GLP-1s, he added.

The study did, however, find an elevated risk for biliary disease (HR, 1.27; 95% CI, 1.02-1.59) in the BMI-matched cohorts.

This could be due to the rapidity of weight loss, Dr. Liu suggested. “We found that semaglutide caused more weight loss at 6 and 12 months than naltrexone/bupropion, and it did so at a faster rate. That falls in line with other data that suggest if you lose weight too fast, you actually have an increased risk of gallstones,” he said.

Rapid weight loss can release cholesterol into the body, which then collects in the bile ducts and causes gallstones. This risk for gallstone formation with rapid weight loss is also seen after bariatric surgery, Dr. Liu said.

Without BMI matching, he noted, the increased risk for biliary disease was no longer significant (HR, 1.21; 95% CI, 0.96-1.52).

The researchers also reported a significant association between GLP-1s and gastroparesis (HR, 2.30; 95% CI, 1.19-4.46), confirming the results of the JAMA study “but at a much lower incidence rate once we excluded all patients with diabetes,” said Dr. Liu. The JAMA study had a HR of 3.67 for gastroparesis (95% CI, 1.15-11.90).
 

Weighing in on the Results

“Overall, their study design looks sound,” said Mahyar Etminan, PharmD, associate professor of medicine at the University of British Columbia in Vancouver and an author of the JAMA study. He agreed that Dr. Liu’s research confirmed their findings about gastroparesis and biliary disease.

However, “I interpret the results with intestinal obstruction and pancreatitis as more inconclusive than no risk,” he added.

Session co-moderator and gastroenterologist and motility specialist with Stanford Health Care in California, Linda Anh Bui Nguyen, MD, AGAF, said that she thinks “it’s a promising study.

“But with any retrospective study where you’re looking at ICD-10 [International Classification of Diseases, Tenth Revision] codes, it really depends on the coders. The code could be subjective and could be wrong,” said Dr. Nguyen, clinical professor of medicine at Stanford Medical School, California.

For example, the diagnosis of gastroparesis requires a normal endoscopy and a gastric emptying test. “But we find that, frequently, patients are being given a diagnosis of gastroparesis without the test,” she said.

An unanswered question also remains regarding how pancreatitis or biliary disease is being diagnosed: “Was it imaging, lab testing, or symptoms?” she said in an interview. “For example, if patients had pain on the right side, did they call it biliary?”

Dr. Nguyen added that it is difficult to get this kind of detail in retrospective studies. She also agreed with Dr. Liu that prospective studies are warranted.

The study was independently supported. Dr. Liu, Dr. Etminan, and Dr. Nguyen had no relevant financial disclosures.

Participants had a BMI ≥ 30 kg/m². In addition to BMI, propensity score matching included demographics, alcohol use, smoking, hyperlipidemia, and abdominal surgery. A second analysis specifically did not match participants for BMI.

The researchers found no significant association between GLP-1s and acute pancreatitis (adjusted hazard ratio [HR], 1.19; 95% CI, 0.66-2.14).

The labeling for semaglutide and liraglutide warns about an increased risk for acute pancreatitis, “but real-world studies and clinical trials are increasingly suggesting there is no increased risk,” Dr. Liu said.

They also did not find a significant association between GLP-1s and bowel obstruction (HR, 1.30; 95% CI, 0.69-2.18).

Despite the current findings, more research — especially prospective data — is needed to confirm pancreatitis as well as other GI risks like bowel obstruction potentially associated with GLP-1s, he added.

The study did, however, find an elevated risk for biliary disease (HR, 1.27; 95% CI, 1.02-1.59) in the BMI-matched cohorts.

This could be due to the rapidity of weight loss, Dr. Liu suggested. “We found that semaglutide caused more weight loss at 6 and 12 months than naltrexone/bupropion, and it did so at a faster rate. That falls in line with other data that suggest if you lose weight too fast, you actually have an increased risk of gallstones,” he said.

Rapid weight loss can release cholesterol into the body, which then collects in the bile ducts and causes gallstones. This risk for gallstone formation with rapid weight loss is also seen after bariatric surgery, Dr. Liu said.

Without BMI matching, he noted, the increased risk for biliary disease was no longer significant (HR, 1.21; 95% CI, 0.96-1.52).

The researchers also reported a significant association between GLP-1s and gastroparesis (HR, 2.30; 95% CI, 1.19-4.46), confirming the results of the JAMA study “but at a much lower incidence rate once we excluded all patients with diabetes,” said Dr. Liu. The JAMA study had a HR of 3.67 for gastroparesis (95% CI, 1.15-11.90).
 

Weighing in on the Results

“Overall, their study design looks sound,” said Mahyar Etminan, PharmD, associate professor of medicine at the University of British Columbia in Vancouver and an author of the JAMA study. He agreed that Dr. Liu’s research confirmed their findings about gastroparesis and biliary disease.

However, “I interpret the results with intestinal obstruction and pancreatitis as more inconclusive than no risk,” he added.

Session co-moderator and gastroenterologist and motility specialist with Stanford Health Care in California, Linda Anh Bui Nguyen, MD, AGAF, said that she thinks “it’s a promising study.

“But with any retrospective study where you’re looking at ICD-10 [International Classification of Diseases, Tenth Revision] codes, it really depends on the coders. The code could be subjective and could be wrong,” said Dr. Nguyen, clinical professor of medicine at Stanford Medical School, California.

For example, the diagnosis of gastroparesis requires a normal endoscopy and a gastric emptying test. “But we find that, frequently, patients are being given a diagnosis of gastroparesis without the test,” she said.

An unanswered question also remains regarding how pancreatitis or biliary disease is being diagnosed: “Was it imaging, lab testing, or symptoms?” she said in an interview. “For example, if patients had pain on the right side, did they call it biliary?”

Dr. Nguyen added that it is difficult to get this kind of detail in retrospective studies. She also agreed with Dr. Liu that prospective studies are warranted.

The study was independently supported. Dr. Liu, Dr. Etminan, and Dr. Nguyen had no relevant financial disclosures.

WASHINGTON — In contrast with a previous study that found glucagon-like peptide 1 (GLP-1) receptor agonists associated with an increased risk for acute pancreatitis and bowel obstruction, a new retrospective study found no significant link to these complications. The new data did, however, reinforce an association between GLP-1s and gastroparesis and biliary disease, specifically gallstones.

One of the big differences from the previous study, published in JAMA in October 2023 by Sodhi and colleagues , is that the current research was able to account for initial body mass index (BMI), said Benjamin Liu, MD, a resident in internal medicine at Case Western Reserve University School of Medicine, Cleveland, Ohio.

This is important, he explained in his presentation (abstract 1074) at the annual Digestive Disease Week^® 2024, because obesity on its own is associated with an increased risk for some of these gastrointestinal (GI) outcomes.

“They did an excellent study,” Dr. Liu said. “But their platform did not allow them to match participants for BMI.”

Another distinction between the two studies is that the JAMA study excluded people who had diabetes 90 days before or 30 days following the start of GLP-1 therapy.

Instead, Dr. Liu said, he and colleague Gengqing Song, MD, “just made it simple” and excluded anyone with diabetes or an A1c ≥ 6.5.

We didn’t want participants with diabetes because “we were looking at GLP-1s for weight loss,” Dr. Liu explained.

Although some clinical trials have already assessed adverse events of these medications, “clinical trials are not always a perfect representation of the real world,” Dr. Liu said in an interview. “So, it’s important to do real-world studies to see just what actually goes on.”
 

Reassessing GI Complications 

In the current study, the researchers identified 105,793 patients from the TriNetX healthcare database taking a GLP-1, either semaglutide or liraglutide, for weight loss and 8794 patients taking 8 mg naltrexone/90 mg bupropion. After propensity matching, including for BMI, there were 8792 patients in each group.

They were identified in the database between 2011 and 2023. Researchers noted their first-ever occurrence of acute pancreatitis, bowel obstruction, gastroparesis, or biliary disease during the study period.

Participants had a BMI ≥ 30 kg/m². In addition to BMI, propensity score matching included demographics, alcohol use, smoking, hyperlipidemia, and abdominal surgery. A second analysis specifically did not match participants for BMI.

WASHINGTON — Statin use may contribute to a significant reduction in the risk of new primary sclerosing cholangitis (PSC) among patients with inflammatory bowel disease (IBD), according to a study presented at Digestive Disease Week^® (DDW) 2024.

Statin use was associated with an 86% risk reduction, and only .09% of IBD patients who took statins developed PSC.

“We all take care of patients with liver disease, and we know what a significant burden PSC is. These patients have a significantly elevated risk of enhanced fibrosis and cirrhosis, multiple cancers, and cholangitis and sepsis,” said lead author Chiraag Kulkarni, MD, a gastroenterology fellow at Stanford (California) University Medical School.

“Despite this, we have to date no proven effective medical care for PSC,” he said. “However, over the last decade, there is growing evidence that statins may be beneficial in liver disease, and we see this evidence base stretching from basic science to clinical data.”

Dr. Kulkarni pointed to numerous studies that indicate statins may slow disease progression in steatotic liver disease, viral hepatitis, and cirrhosis. But could statins prevent the onset of PSC?

Because PSC incidence is low, Dr. Kulkarni and colleagues focused on a patient population with higher prevalence — those with IBD, who have an overall lifetime risk of 2% to 7%. The research team followed patients from the date of IBD diagnosis.

Among 33,813 patients with IBD in a national dataset from 2018 onward, 8813 used statins. Statin users tended to be older than non–statin users.

Overall, 181 patients developed new onset PSC during a median follow-up of about 45 months after initial IBD diagnosis. Only eight statin users (.09%) developed PSC, compared with 173 patients (.69%) in the control group.

In a propensity score-matched analysis, statin therapy was associated with a significantly lower risk of developing PSC (HR .14, P < .001). The associated E-value was 5.5, which suggested a robust finding and unlikely to be due to non-visible confounding.

The findings were consistent across secondary and sensitivity analyses, including by age, duration of statin use, and type of statin. For instance, for patients under age 50 where PSC is more likely to occur, statins were associated with a 90% reduction in PSC risk.

“We take away two things from this. First, it’s suggested that a protective effect occurs at ages where PSC is most likely to occur,” Dr. Kulkarni said. “Second, in combination with our propensity score-matched analysis, the results we are observing are not due to a survival bias, where the patients who survive to an age where statins are prescribed simply have a biologically different predilection for developing PSC.”

Statins also protected against PSC in both ulcerative colitis (HR .21) and Crohn’s disease (HR .15), as well as both women (HR .16) and men (HR .22).

Given the uncertainty about the optimal duration of statin therapy for a protective effect, Dr. Kulkarni and colleagues looked at a lag time of 12 months. They found statins were associated with an 84% risk reduction (HR .16), which was similar to the primary analysis.

The study was limited by the inability to capture dosage data or medication adherence. The findings raised several questions, Dr. Kulkarni said, such as the underlying mechanisms and clinical implications. For instance, the underlying mechanisms appear to be related to the pleiotropic effect of statins, modulation of gut inflammation, and alterations in bile acid profiles.

“This is really fascinating and interesting. I wonder about this as a primary prevention strategy in those who have normal cholesterol. Could this work or not?” said Gyongyi Szabo, MD, AGAF, chief academic officer at Beth Israel Deaconess Medical Center, Boston, who was a moderator for the Liver & Biliary Section Distinguished Abstract Plenary Session.

PHOENIX — Immunosuppression is an independent risk factor for poorer outcomes in patients with cutaneous squamous cell carcinoma (cSCC), according to new research that was presented at the American College of Mohs Surgery (ACMS) 2024 annual meeting.

Even though immunosuppression is strongly associated with an increased risk for cSCC, studies to date have generally not shown it to be an independent risk factor for metastasis and disease-specific death (DSD), after accounting for primary tumor stage.

“Solid organ transplant puts patients at risk for developing cutaneous squamous cell carcinoma, and it’s more likely to have aggressive features,” said study author Jason Klein, MD, PhD, a dermatology resident at University of Texas Southwestern Medical Center, Dallas. “But it’s still not known if immunosuppression is an independent risk factor.”

Other groups “have tried to tackle this, but they have all primarily been single-institution data,” he noted, adding that “results so far have been tipping the scale towards immunosuppression not being an independent risk factor” for worse outcomes.

Immunosuppressed individuals face a greater risk for cSCC than the general population and often present with more aggressive, multifocal disease. However, Dr. Klein explained that a previous retrospective study comprising a cohort of approximately 7600 tumors from two centers reported that immunosuppression was not an independent risk factor for both tumor metastasis and cancer-specific death after adjusting for tumor characteristics.

Tipped the Scale

Therefore, the goal of the current study was to repeat this analysis but in a much larger retrospective cohort. Dr. Klein and his colleagues pooled cSCC data from 12 dermatology centers (11 academic and one private) that were located in the United States, Spain, and Brazil. The cohort included 4392 patients (3769 immunocompetent patients and 623 immunosuppressed patients) with 19,237 tumors (15,191 immunocompetent and 4046 immunosuppressed). Study endpoints included local recurrence, metastasis (nodal, satellite/in-transit, and distant), DSD, and “major poor outcomes” (defined as metastasis and DSD combined).

About 30% of the immunosuppressed patients were organ transplant recipients (OTR) and 10% had chronic lymphocytic leukemia (CLL). Half of the immunocompetent patients (50.3%) underwent Mohs surgery as the primary treatment, as did 58.2% of the immunosuppressed patients.

On multivariable analysis, significant predictors of “major poor outcomes” included immunosuppression (subdistribution hazard ratio [SHR], 1.3; P = .04), Brigham and Women’s Hospital tumor stage (SHR 6.7 for T2a, 18.1 for T2b, and 37.2 for T3; P < .001 for all), location on the head/neck (SHR, 2.1; P < .001), and adjuvant radiation (SHR, 1.6; P < .001).

But when metastasis and DSD were evaluated separately, immunosuppression was only predictive of DSD (SHR, 1.7; P = .008) but not metastasis (SHR, 1.2; P = .21). Dr. Klein explained that they also conducted a separate subanalysis limited to OTR and patients with CLL, which demonstrated that immunosuppression was no longer a significant predictor of “major poor outcomes” (SHR, 0.9; P = .66 for OTR; SHR, 1.4; P = .25 for CLL).

“Organ transplant status and CLL were not independent risk factors for major poor outcomes,” he said. “But in summary, we may be tipping the scale to immunosuppression being a risk factor.”

Asked to comment on the findings, Naissan O. Wesley, MD, director of Mohs surgery, Skin Care and Laser Physicians of Beverly Hills, Los Angeles, California, stated that “this larger scale study presented at this meeting was important to further confirm what we see in everyday practice, that immunosuppression may lead to poorer outcomes in patients with cutaneous squamous cell carcinoma.”

Also weighing in on the data, Jesse M. Lewin, MD, chief of Mohs micrographic and dermatologic surgery, at the Icahn School of Medicine at Mount Sinai, New York City, noted that the treatment of cSCC in high-risk patients has been challenging because of the historical lack of data and large studies to guide management.

“The authors provide a large cohort to help stratify which patients are most at risk for poor outcomes, which can inform our decision to refer for neoadjuvant or adjuvant treatment and multi-disciplinary management,” he said. “This is the first step in being able to optimize cure in these patients.”

The study was independently supported. Dr. Klein, Dr. Lewin, and Dr. Wesley reported no relevant financial relationships.

Dr. Klein explained that they also conducted a separate subanalysis limited to OTR and patients with CLL, which demonstrated that immunosuppression was no longer a significant predictor of “major poor outcomes” (SHR, 0.9; P = .66 for OTR; SHR, 1.4; P = .25 for CLL).

“Organ transplant status and CLL were not independent risk factors for major poor outcomes,” he said. “But in summary, we may be tipping the scale to immunosuppression being a risk factor.”

Asked to comment on the findings, Naissan O. Wesley, MD, director of Mohs surgery, Skin Care and Laser Physicians of Beverly Hills, Los Angeles, California, stated that “this larger scale study presented at this meeting was important to further confirm what we see in everyday practice, that immunosuppression may lead to poorer outcomes in patients with cutaneous squamous cell carcinoma.”

Also weighing in on the data, Jesse M. Lewin, MD, chief of Mohs micrographic and dermatologic surgery, at the Icahn School of Medicine at Mount Sinai, New York City, noted that the treatment of cSCC in high-risk patients has been challenging because of the historical lack of data and large studies to guide management.

“The authors provide a large cohort to help stratify which patients are most at risk for poor outcomes, which can inform our decision to refer for neoadjuvant or adjuvant treatment and multi-disciplinary management,” he said. “This is the first step in being able to optimize cure in these patients.”

The study was independently supported. Dr. Klein, Dr. Lewin, and Dr. Wesley reported no relevant financial relationships.

PHOENIX — There is a high prevalence of emotional and physical burden associated with being a Mohs surgeon, particularly among women and younger surgeons, according to new findings. In addition, most surgeons did not feel prepared to manage or prevent these symptoms.

“Our study highlights the need to implement ergonomic training and emotion-focused coping skills, as part of fellowship training and the continuing medical education curriculum, to alleviate and prevent emotional burnout,” said lead author Eduardo A. Michelen-Gómez, MD, a dermatology resident at the University of Puerto Rico School of Medicine, San Juano. “This interaction also must be designed to cater to generation and sex specific needs.”

Dr. Michelen-Gómez presented the findings at the annual meeting of the American College of Mohs Surgery.

Mohs is a demanding procedure that involves repetitive motion, strict attention to detail, and high practice efficiency, all of which must be balanced with the need to prioritize patient safety and well-being. “All of these factors predispose Mohs surgeons to be at an increased risk of physical and emotional stress,” he said.

Despite these concerns, however, the literature is limited concerning work-associated stressors among Mohs surgeons. To further explore this issue, Dr. Michelen-Gómez and colleagues conducted a survey study of ACMS members to investigate not only the prevalence of emotional and physical stressors associated with being a Mohs surgeon but also what specific actions physicians were taking to prevent and/or treat these stressors.

They designed a 21-question cross-sectional electronic survey that was sent to all active ACMS members in 2023. Outcomes evaluated were gender, years of practice, concern for and prevalence of occupational musculoskeletal disorders, emotional stress and burnout, and surgeon’s knowledge and training to manage these symptoms. A total of 473 Mohs surgeons responded.
 

High Prevalence of Injury and Burnout

“Almost 90% of respondents reported moderate to severe concern for occupational musculoskeletal injuries,” said Dr. Michelen-Gómez. “The prevalence of these injuries was 68%, with neck injuries being the most common complaint. Of the entire cohort, 67% have adopted ergonomic practices patterns.”

Female surgeons had a higher prevalence of musculoskeletal injuries than men, and there was no correlation between years of practice and prevalence of these injuries.

Their results also showed that 70% of respondents reported experiencing psychological and emotional stress or burnout associated with being a Mohs surgeon. The cause of emotional stress differed between men and women. “In males, the most common cause was patient care–related anxiety, while in females, it was finding an adequate work-life balance,” he said.

Surgeons with fewer years of experience were more likely to experience emotional stress (P = .01), and female surgeons had a higher prevalence of burnout and musculoskeletal disorders (71.0% and 71.4%, respectively) than male surgeons (67.7% and 65.2%, respectively).

To prevent or manage musculoskeletal injury, respondents reported using interventions such as physical therapy, yoga/stretching/Pilates, massage therapy, cupping, and using a physical trainer. Specific actions for preventing or managing emotional stress and burnout included engaging with a therapist, working with a life coach, practicing meditation or mindfulness, journaling, relying on religion or spirituality, and exercise.

However, among those who reported musculoskeletal disorders or emotional stress, only 40.56% and 46.67%, respectively, felt they had sufficient knowledge and the resources to manage them appropriately.

“In addition, we found a positive correlation between the development of psychological stress and physical issues,” said Dr. Michelen-Gómez. Future studies can include determining the most effective methods to address the emotional and physical stressors of practicing Mohs Surgery.”

Asked to comment on the study findings, Jesse M. Lewin, MD, chief of Mohs micrographic and dermatologic surgery and vice chair of surgical operations at the Icahn School of Medicine at Mount Sinai, New York City, said that the real-world take-home messages from this study are twofold.

“It is important to focus on physician wellness and prevention of burnout and physical injury to protect our physician workforce, and two, we should equip physicians-in-training with tools to protect their physical and emotional health,” he said.

Dr. Michelen-Gómez and Dr. Lewin, who was not involved with the study, had no relevant disclosures.

SAN FRANCISCO — Primary care providers placed contraceptive intrauterine devices (IUDs) incorrectly nearly twice as often as ob.gyn. providers at a single institution, according to data presented at the annual meeting of the American College of Obstetricians and Gynecologists.

“Adequate training for providers regarding proper techniques for IUD insertion is imperative for good clinical practice, patient satisfaction, and effectiveness of the LARC [long-acting reversible contraceptive],” Kerrilyn Hewell, MD, a fourth-year resident ob.gyn. at Southern Illinois University in Springfield, reported. “Primary care providers are often seen for contraception management. Therefore, the significantly higher malpositioned rate indicates the need to implement an enhanced simulation/education curriculum for IUD insertion.”

Kevin Ault, MD, a professor and chair of the Department of Obstetrics and Gynecology at Western Michigan University Homer Stryker M.D. School of Medicine, was not involved in the study but said it was not surprising.

“The reasons for obtaining an ultrasound are not discussed in the abstract, so the primary care physicians may have found more problems by ordering more ultrasounds,” Dr. Ault told this news organization. “The takeaway would be to order an ultrasound if you are unsure of placement of the IUD. Malpositioned IUDs may be at risk for expulsion and women may be at risk for unplanned pregnancy.”

The researchers conducted a retrospective review of all adult women’s ultrasounds from the ob.gyn. department of the Southern Illinois University School of Medicine between 2017 and 2020 in which an IUD was documented. Two physicians certified by the American Institute of Ultrasound in Medicine interpreted the images to determine whether the IUD was positioned correctly.

Among 602 ultrasounds included, 562 of the IUDs were placed by an ob.gyn., and 40 were placed by a primary care provider. Most of the IUDs were properly positioned (82%) while 18% were malpositioned. When the researchers compared positioning by specialty, they found that 30% of the malpositioned IUDs had been placed by primary care providers, compared to 17% of malpositioned IUDs placed by an ob.gyn. (P = .043).

The most common type of malpositioning was placement low in the cervix (40.4%) or low but not in the cervix (25.7%). Other types of malpositioning included a deviated axis, the device being inverted or transverse, the IUD arms being folded, the device being embedded, or the device placed outside the uterus.

Of the 136 IUDs placed by an ob.gyn. resident, 17% were malpositioned. Only 6 IUDs had been placed by a primary care resident, and one was malpositioned. Among midlevel providers, 17% of 78 IUDs placed by an ob.gyn. and 33% (5) of 15 IUDs placed by a primary care provider were malpositioned. Among attending physicians, 18% of the 348 IUDs placed by an ob.gyn. and 30% of the 40 IUDs placed by a primary care provider were malpositioned.

No external funding was noted, and the authors and Dr. Ault had no disclosures.

BASEL, SWITZERLAND — New findings challenge the practice of rapidly lowering blood pressure (BP) in acute ischemic stroke to allow for speedy thrombolysis.

The observational cluster study showed that patients treated in hospitals that followed the guideline-recommended practice of rapidly reducing BP did no better — and actually showed a trend toward worse outcomes — than those treated in hospitals that did not lower BP, even though this meant fewer patient received thrombolysis. 

“We found insufficient evidence to recommend active blood pressure lowering in patients with ischemic stroke who have blood pressure levels exceeding the guidelines but are otherwise eligible for thrombolytic therapy,” said senior study author Nyika D. Kruyt, MD, PhD, Leiden University Medical Center, the Netherlands. 

“Our results suggest that if the blood pressure is too high for thrombolysis, then it is best to wait and only treat with thrombolysis if the blood pressure drops spontaneously,” Dr. Kruyt said.

The findings were presented at the European Stroke Organisation Conference (ESOC) annual meeting and published online in The Lancet Neurology. 
 

Guidelines Without Evidence?

Owing to concerns about high BP increasing the risk for intracerebral hemorrhage after thrombolysis, the original trials evaluating thrombolysis in stroke set an arbitrary threshold of 185/110 mm Hg, which has been incorporated into stroke guidelines. These trials cautioned against lowering BP rapidly, which is not included in guidelines. 

Most stroke centers therefore tend to rapidly lower BP in patients who have values greater than 185/110 mm Hg and who are otherwise eligible for thrombolysis, investigators noted. Because thrombolysis is more effective the earlier it is administered, there is some urgency to reduce the BP quickly when patients first arrive at the hospital. 

“But there has never been any evidence for the lowering of blood pressure with IV [intravenous] antihypertensives before thrombolysis, and some centers have never adopted this approach because of concerns that a rapid decline in blood pressure may reduce perfusion of the brain at a time when there is already ischemia present,” Dr. Kruyt noted. 

However, if BP is lowered quickly, there is a greater chance that patients will not be able to receive thrombolysis because the 4.5-hour time limit could be exceeded.

For the prospective, observational TRUTH study, researchers compared outcomes in 853 patients treated at 27 stroke centers in the Netherlands with an active BP-lowering strategy vs 199 patients treated at 10 hospitals with no such strategy. 

Baseline characteristics of participants in the two groups were similar. 

Results showed a strong trend toward worse outcomes in participants whose BP was lowered, with an adjusted odds ratio (aOR) for a shift toward a worse 90-day functional outcome on the modified Rankin Scale of 1.27 (95% CI, 0.96-1.68). 

This was despite the fact that many more patients whose BP was reduced received thrombolysis (94% vs 52% of those with no BP lowering) and had shorter times to treatment, with average door-to-needle times of 35 minutes (vs 47 minutes among those with no BP lowering). 

Symptomatic intracranial hemorrhage occurred in 5% of the active BP-lowering group versus 3% of those who did not have their BP lowered (aOR, 1.28; 95% CI, 0.62-2.62).
 

Reconsider Guidelines?

These results are consistent with those from the INTERACT4 trial, which was also presented at the ESOC 2024 meeting. That trial showed a harmful effect of lowering BP in the ambulance in patients with acute ischemic stroke, but a beneficial effect in patients with hemorrhagic stroke.

“I think the guidelines need to be reconsidered after these studies and we should refrain from active blood pressure–lowering in patients with acute ischemic stroke,” Dr. Kruyt said. 

But he acknowledged that not rapidly lowering BP will mean fewer patients will be able to receive thrombolysis within the 4.5-hour treatment window.

Dr. Kruyt estimated that the combination of being eligible for thrombolysis, with the only exclusion criterion being BP greater than 185/110 mm Hg, applies to about 10%-15% of patients. 

“If we have a watch-and-wait policy, then about half of those patients will still get treated with thrombolysis within in the 4.5-hour limit but later than if blood pressure was reduced with IV antihypertensives,” he added. 

Dr. Kruyt noted that there has never been a randomized trial on the practice of BP lowering in order to be able to administer thrombolysis. 

“The 185/110 mm Hg blood pressure level is an arbitrary threshold that was chosen for the original thrombolysis stroke trials,” he said. “I believe we need trials to investigate whether we can give thrombolysis safely to patients with higher blood pressure levels than this, without needing to rapidly reduce the pressure.”
 

Caution Advised

Discussing the TRUTH study at the ESOC meeting, Guillaume Turc, MD, professor of neurology at Sainte-Anne Hospital, Paris, said he thought the findings were “very thought provoking.”

Simona Sacco, MD, professor of neurology at the University of L’Aquila, Italy, said the result was surprising, but she advised caution in acting on this finding. 

“I don’t think this study can change practice or guidelines as it is not a randomized trial. Yes, it can generate a hypothesis, but we need more research before changing clinical practice,” she said. 

In an accompanying editorial, Verónica Olavarría, MD, Clínica Alemana Universidad del Desarrollo, Santiago, Chile, also suggested the trial should be interpreted cautiously because there was “insufficient evidence for a definitive conclusion.”

But Dr. Kruyt noted that even though the TRUTH study was not a randomized trial, the results are in line with those of recent randomized trials such as INTERACT4.

He added that the ENCHANTED trial also showed no benefit of intensive BP management immediately after thrombolysis in mild to moderate stroke and even suggested harm in severe stroke. And other trials (OPTIMAL-BP and ENCHANTED2/MT) have shown worse outcomes with BP lowering in patients with acute ischemic stroke undergoing thrombectomy. 

“All these studies are showing similar signals throughout the whole timeline in acute ischemic stroke. The results are very much in line with each other. I think this strengthens our findings,” Dr. Kruyt said. 

“With this data, I think the guidelines should be revised, and until randomized data become available showing that reducing blood pressure in acute ischemic stroke patients in order for them to receive early thrombolysis is beneficial, then we should refrain from doing so,” he added.

INTERACT4 investigator Craig Anderson, MD, George Institute for Global Health, Sydney, New South Wales, Australia, agreed. 

“The TRUTH study gives the same message as INTERACT4. They are completely in line with each other, both suggesting harm with blood pressure lowering in acute ischemic stroke. These two together are going to rattle the cage around blood pressure control in acute ischemic stroke patients,” Dr. Anderson said. 

The TRUTH study was funded by a grant from Fonds NutsOhra. Dr. Kruyt reported no relevant financial disclosures. Dr. Olavarría reported receiving a grant from Boehringer Ingelheim for the RECCA registry and honoraria from Novo Nordisk.

These results are consistent with those from the INTERACT4 trial, which was also presented at the ESOC 2024 meeting. That trial showed a harmful effect of lowering BP in the ambulance in patients with acute ischemic stroke, but a beneficial effect in patients with hemorrhagic stroke.

“I think the guidelines need to be reconsidered after these studies and we should refrain from active blood pressure–lowering in patients with acute ischemic stroke,” Dr. Kruyt said. 

But he acknowledged that not rapidly lowering BP will mean fewer patients will be able to receive thrombolysis within the 4.5-hour treatment window.

Dr. Kruyt estimated that the combination of being eligible for thrombolysis, with the only exclusion criterion being BP greater than 185/110 mm Hg, applies to about 10%-15% of patients. 

“If we have a watch-and-wait policy, then about half of those patients will still get treated with thrombolysis within in the 4.5-hour limit but later than if blood pressure was reduced with IV antihypertensives,” he added. 

Dr. Kruyt noted that there has never been a randomized trial on the practice of BP lowering in order to be able to administer thrombolysis. 

“The 185/110 mm Hg blood pressure level is an arbitrary threshold that was chosen for the original thrombolysis stroke trials,” he said. “I believe we need trials to investigate whether we can give thrombolysis safely to patients with higher blood pressure levels than this, without needing to rapidly reduce the pressure.”
 

Caution Advised

Discussing the TRUTH study at the ESOC meeting, Guillaume Turc, MD, professor of neurology at Sainte-Anne Hospital, Paris, said he thought the findings were “very thought provoking.”

Simona Sacco, MD, professor of neurology at the University of L’Aquila, Italy, said the result was surprising, but she advised caution in acting on this finding. 

“I don’t think this study can change practice or guidelines as it is not a randomized trial. Yes, it can generate a hypothesis, but we need more research before changing clinical practice,” she said. 

In an accompanying editorial, Verónica Olavarría, MD, Clínica Alemana Universidad del Desarrollo, Santiago, Chile, also suggested the trial should be interpreted cautiously because there was “insufficient evidence for a definitive conclusion.”

But Dr. Kruyt noted that even though the TRUTH study was not a randomized trial, the results are in line with those of recent randomized trials such as INTERACT4.

He added that the ENCHANTED trial also showed no benefit of intensive BP management immediately after thrombolysis in mild to moderate stroke and even suggested harm in severe stroke. And other trials (OPTIMAL-BP and ENCHANTED2/MT) have shown worse outcomes with BP lowering in patients with acute ischemic stroke undergoing thrombectomy. 

“All these studies are showing similar signals throughout the whole timeline in acute ischemic stroke. The results are very much in line with each other. I think this strengthens our findings,” Dr. Kruyt said. 

“With this data, I think the guidelines should be revised, and until randomized data become available showing that reducing blood pressure in acute ischemic stroke patients in order for them to receive early thrombolysis is beneficial, then we should refrain from doing so,” he added.

INTERACT4 investigator Craig Anderson, MD, George Institute for Global Health, Sydney, New South Wales, Australia, agreed. 

“The TRUTH study gives the same message as INTERACT4. They are completely in line with each other, both suggesting harm with blood pressure lowering in acute ischemic stroke. These two together are going to rattle the cage around blood pressure control in acute ischemic stroke patients,” Dr. Anderson said. 

The TRUTH study was funded by a grant from Fonds NutsOhra. Dr. Kruyt reported no relevant financial disclosures. Dr. Olavarría reported receiving a grant from Boehringer Ingelheim for the RECCA registry and honoraria from Novo Nordisk.

BASEL, SWITZERLAND — New findings challenge the practice of rapidly lowering blood pressure (BP) in acute ischemic stroke to allow for speedy thrombolysis.

The observational cluster study showed that patients treated in hospitals that followed the guideline-recommended practice of rapidly reducing BP did no better — and actually showed a trend toward worse outcomes — than those treated in hospitals that did not lower BP, even though this meant fewer patient received thrombolysis. 

“We found insufficient evidence to recommend active blood pressure lowering in patients with ischemic stroke who have blood pressure levels exceeding the guidelines but are otherwise eligible for thrombolytic therapy,” said senior study author Nyika D. Kruyt, MD, PhD, Leiden University Medical Center, the Netherlands. 

“Our results suggest that if the blood pressure is too high for thrombolysis, then it is best to wait and only treat with thrombolysis if the blood pressure drops spontaneously,” Dr. Kruyt said.

The findings were presented at the European Stroke Organisation Conference (ESOC) annual meeting and published online in The Lancet Neurology. 
 

Guidelines Without Evidence?

Owing to concerns about high BP increasing the risk for intracerebral hemorrhage after thrombolysis, the original trials evaluating thrombolysis in stroke set an arbitrary threshold of 185/110 mm Hg, which has been incorporated into stroke guidelines. These trials cautioned against lowering BP rapidly, which is not included in guidelines. 

Most stroke centers therefore tend to rapidly lower BP in patients who have values greater than 185/110 mm Hg and who are otherwise eligible for thrombolysis, investigators noted. Because thrombolysis is more effective the earlier it is administered, there is some urgency to reduce the BP quickly when patients first arrive at the hospital. 

“But there has never been any evidence for the lowering of blood pressure with IV [intravenous] antihypertensives before thrombolysis, and some centers have never adopted this approach because of concerns that a rapid decline in blood pressure may reduce perfusion of the brain at a time when there is already ischemia present,” Dr. Kruyt noted. 

However, if BP is lowered quickly, there is a greater chance that patients will not be able to receive thrombolysis because the 4.5-hour time limit could be exceeded.

For the prospective, observational TRUTH study, researchers compared outcomes in 853 patients treated at 27 stroke centers in the Netherlands with an active BP-lowering strategy vs 199 patients treated at 10 hospitals with no such strategy. 

Baseline characteristics of participants in the two groups were similar. 

Results showed a strong trend toward worse outcomes in participants whose BP was lowered, with an adjusted odds ratio (aOR) for a shift toward a worse 90-day functional outcome on the modified Rankin Scale of 1.27 (95% CI, 0.96-1.68). 

This was despite the fact that many more patients whose BP was reduced received thrombolysis (94% vs 52% of those with no BP lowering) and had shorter times to treatment, with average door-to-needle times of 35 minutes (vs 47 minutes among those with no BP lowering). 

Symptomatic intracranial hemorrhage occurred in 5% of the active BP-lowering group versus 3% of those who did not have their BP lowered (aOR, 1.28; 95% CI, 0.62-2.62).
