TOPLINE:

Adolescent girls with polycystic ovary syndrome (PCOS) have an increased risk for hypertension, according to a new study which underscores the importance of blood pressure surveillance in this population.

METHODOLOGY:

• The retrospective cohort study examined the association between PCOS and hypertension in adolescent girls within a diverse community-based US healthcare population.
• The researchers analyzed data from 224,418 adolescent girls (mean age at index visit, 14.9 years; 15.8% classified as having obesity) who had a well-child visit between 2013 and 2019, during which their systolic blood pressure and diastolic blood pressure were measured.
• Blood pressure in the hypertensive range was classified using the 2017 American Academy of Pediatrics Practice Guideline, with thresholds of 130/80 mm Hg or greater.

TAKEAWAY:

• The proportion of adolescent girls with high blood pressure was significantly greater among those with PCOS than among those without the condition (18.2% vs 7.1%; P < .001).
• Adolescent girls with PCOS had a 25% higher risk for hypertension than those without the disorder (adjusted odds ratio [aOR], 1.25; 95% CI, 1.10-1.42).
• Similarly, adolescent girls with obesity and PCOS had a 23% higher risk for high blood pressure than those without PCOS (aOR, 1.23; 95% CI, 1.06-1.42).

IN PRACTICE:

“The high prevalence of [hypertension] associated with PCOS emphasizes the key role of early [blood pressure] monitoring in this high-risk group,” the authors of the study wrote.

SOURCE:

The study was led by Sherry Zhang, MD, Kaiser Permanente Oakland Medical Center, Oakland, California, and was published online in the American Journal of Preventive Medicine.

LIMITATIONS:

The study relied on coded diagnoses of PCOS from clinical settings, which may have led to detection and referral biases. The findings may not be generalizable to an unselected population in which adolescent girls are systematically screened for both PCOS and hypertension.

DISCLOSURES:

This study was funded by the Cardiovascular and Metabolic Conditions Research Section and the Biostatistical Consulting Unit at the Division of Research, Kaiser Permanente Northern California and by the Kaiser Permanente Northern California Community Health Program. The authors declared having no conflicts of interest.

TOPLINE:

Patients with dry eye disease are more than three times as likely to have mental health conditions, such as depression and anxiety, as those without the condition.

METHODOLOGY:

• Researchers used a database from the National Institutes of Health to investigate the association between dry eye disease and mental health disorders in a large and diverse nationwide population of American adults.
• They identified 18,257 patients (mean age, 64.9 years; 67% women) with dry eye disease who were propensity score–matched with 54,765 participants without the condition.
• The cases of dry eye disease were identified using Systematized Nomenclature of Medicine codes for dry eyes, meibomian gland dysfunction, and tear film insufficiency.
• The outcome measures for mental health conditions were clinical diagnoses of depressive disorders, anxiety-related disorders, bipolar disorder, and schizophrenia spectrum disorders.

TAKEAWAY:

• Patients with dry eye disease had more than triple the risk for mental health conditions than participants without the condition (adjusted odds ratio [aOR], 3.21; P < .001).
• Patients with dry eye disease had a higher risk for a depressive disorder (aOR, 3.47), anxiety-related disorder (aOR, 2.74), bipolar disorder (aOR, 2.23), and schizophrenia spectrum disorder (aOR, 2.48; P < .001 for all) than participants without the condition.
• The associations between dry eye disease and mental health conditions were significantly stronger among Black individuals than among White individuals, except for bipolar disorder.
• Dry eye disease was associated with two- to threefold higher odds of depressive disorders, anxiety-related disorders, bipolar disorder, and schizophrenia spectrum disorders even in participants who never used medications for mental health (P < .001 for all).

IN PRACTICE:

“Greater efforts should be undertaken to screen patients with DED [dry eye disease] for mental health conditions, particularly in historically medically underserved populations,” the authors of the study wrote.

SOURCE:

This study was led by Aaron T. Zhao, of the Perelman School of Medicine at the University of Pennsylvania, Philadelphia, and was published online on October 15, 2024, in the American Journal of Ophthalmology.

LIMITATIONS:

This study relied on electronic health record data, which may have led to the inclusion of participants with undiagnosed dry eye disease as control participants. Moreover, the study did not evaluate the severity of dry eye disease or the severity and duration of mental health conditions, which may have affected the results. The database analyzed in this study may not have fully captured the complete demographic profile of the nationwide population, which may have affected the generalizability of the findings.

DISCLOSURES:

This study was supported by funding from the National Institutes of Health and Research to Prevent Blindness. The authors declared having no conflicts of interest.

TOPLINE:

Higher doses of vitamin D3 supplementation did not significantly reduce cardiac biomarkers in older adults with low serum vitamin D levels. The STURDY trial found no significant differences in high-sensitivity cardiac troponin I (hs-cTnI) and N-terminal pro-B-type natriuretic peptide (NT-proBNP) between low- and high-dose groups.

METHODOLOGY:

• A total of 688 participants aged 70 years or older with low serum 25-hydroxy vitamin D levels (10-29 ng/mL) were included in the STURDY trial.
• Participants were randomized to receive one of four doses of vitamin D3 supplementation: 200, 1000, 2000, or 4000 IU/d, with 200 IU/d as the reference dose.
• Cardiac biomarkers, including hs-cTnI and NT-proBNP, were measured at baseline, 3 months, 12 months, and 24 months.
• The trial was conducted at two community-based research institutions in the United States between July 2015 and March 2019.
• The effects of vitamin D3 dose on biomarkers were assessed via mixed-effects tobit models, with participants followed up to 24 months or until study termination.

TAKEAWAY:

• Higher doses of vitamin D3 supplementation did not significantly affect hs-cTnI levels compared with the low-dose group (1.6% difference; 95% CI, −5.3 to 8.9).
• No significant differences were observed in NT-proBNP levels between the high-dose and low-dose groups (−1.8% difference; 95% CI, −9.3 to 6.3).
• Both hs-cTnI and NT-proBNP levels increased in both low- and high-dose groups over time, with hs-cTnI increasing by 5.2% and 7.0%, respectively, and NT-proBNP increasing by 11.3% and 9.3%, respectively.
• The findings suggest that higher doses of vitamin D3 supplementation do not reduce markers of subclinical cardiovascular disease in older adults with low serum vitamin D levels.

IN PRACTICE:

“We can speculate that the systemic effects of vitamin D deficiency are more profound among the very old, and there may be an inverse relationship between supplementation and inflammation. It is also possible that serum vitamin D level is a risk marker but not a risk factor for CVD risk and related underlying mechanisms,” wrote the authors of the study.

SOURCE:

The study was led by Katharine W. Rainer, MD, Beth Israel Deaconess Medical Center in Boston. It was published online in the Journal of the American College of Cardiology.

LIMITATIONS:

The study’s community-based population may limit the generalizability of the findings to populations at higher risk for cardiovascular disease. Additionally, the baseline cardiac biomarkers were lower than those in some high-risk populations, which may affect the precision of the assay performance. The study may not have had adequate power for cross-sectional and subgroup analyses. Both groups received some vitamin D3 supplementation, making it difficult to determine the impact of lower-dose supplementation vs no supplementation.

DISCLOSURES:

The study was supported by grants from the National Institute on Aging, the Office of Dietary Supplements, the Mid-Atlantic Nutrition Obesity Research Center, and the Johns Hopkins Institute for Clinical and Translational Research. Rainer disclosed receiving grants from these organizations.

SAVANNAH, GEORGIA — Heart problems are common in the vast majority of neuromuscular disorders, and cardiac monitoring of patients is crucial, even at younger ages, a neurologist told an audience of nerve/muscle specialists.

The cardiac conditions can range from asymptomatic to potentially lethal, Nicholas J. Silvestri, MD, professor of neurology at the Jacobs School of Medicine and Biomedical Sciences, University at Buffalo, in New York, said in a presentation at the American Association of Neuromuscular & Electrodiagnostic Medicine (AANEM) 2024. “It’s really important to know when to do tests and refer to cardiology, and it’s really important to find a cardiologist who can work in concert in taking care of these patients.”
 

Protein Alterations May Disrupt Heart Muscles

In muscular dystrophies, a prevailing theory suggests that alterations to proteins such as dystrophin disrupt structural integrity in both muscle and cardiac cells, he said.

In Duchenne muscular dystrophy (DMD), cardiomyopathy, cardiac conduction abnormalities, or both usually appear in patients by age 10. “It’s important to know that it’s probably present to some degree before that, and it’s not going to get better over time,” he said.

Cardiac problems are universal in DMD by age 18, he said. “Men and boys are living longer, so they have the opportunity to develop the cardiac abnormalities that accrue with time.” Conduction abnormalities typically appear first. “In a lot of these boys, you’ll typically see persistent sinus tachycardia. But they can also develop atrial arrhythmias and bundle branch blocks.”

Sudden cardiac death is responsible for mortality in an estimated 15% patients with DMD. “Very sadly, I lost a patient this way just a few months ago,” Silvestri said.
 

ECGs and Echos Are Recommended

Screening is crucial. “Make sure that patients get that referral and get these tests done,” he said. “You need an ECG and echo by diagnosis or age 6. This is usually repeated annually or biannually, typically by the cardiologist you’re working with.”

The good news is that there’s evidence of survival benefits from treatment with angiotensin-converting enzyme inhibitors for dilated cardiomyopathy. “Some cardiac experts feel treatment with angiotensin receptor blockers (ARBs) is equivalent.”

Most boys will get echocardiograms, he said, “but there’s a lot of evidence showing that cardiac MRI is probably preferable for a number of reasons,” including better visualization. But the need for sedation limits access, he said, and cardiac MRI may not be available at some facilities.
 

Worse Outcomes in Becker Muscular Dystrophy (BMD)

Cardiac involvement is more common and more severe in BMD than in DMD. About 50% of deaths in BMD are attributed to malignant arrhythmias or congestive heart failure, he said.

Screening requirements and treatment options in BMD are similar to those in DMD, with the added option of heart transplantation.

Silvestri cautioned that up to 40% of female carriers of dystrophin mutations can develop cardiac dysfunction similar to that seen in DMD and BMD. Cardiac assessments are recommended every 5 years. “It’s important to genotype Mom,” he said, especially in light of the fact that two thirds of DMD cases may be inherited.

“When I send genetic testing on the mother and find her to be a carrier, I send her to a cardiologist so she has the appropriate screening done,” he said.
 

Pacemakers May Be Considered in Type 1 Myotonic Dystrophy

In type 1 myotonic dystrophy, cardiac conduction abnormalities are seen in two thirds of patients, and sudden cardiac death in up to 30% of patients. “When it is diagnosed, patients do need an ECG at that time, as well as annually,” he said.

Holter monitoring or implantable loop recorders may be recommended, and permanent pacing via an implantable cardioverter-defibrillator might be appropriate.

“Based on the literature to date, the exact timing is not is not clear,” Silvestri said. “The electrophysiologists in my area tend to be very aggressive, thankfully, and treat them fairly soon with pacemakers when we see the first sign of trouble.”

Silvestri disclosed consultant/advisory relationships with argenx, Alexion, Amgen, UCB, Immunovant, and Janssen.

SAVANNAH, GEORGIA — Heart problems are common in the vast majority of neuromuscular disorders, and cardiac monitoring of patients is crucial, even at younger ages, a neurologist told an audience of nerve/muscle specialists.

The cardiac conditions can range from asymptomatic to potentially lethal, Nicholas J. Silvestri, MD, professor of neurology at the Jacobs School of Medicine and Biomedical Sciences, University at Buffalo, in New York, said in a presentation at the American Association of Neuromuscular & Electrodiagnostic Medicine (AANEM) 2024. “It’s really important to know when to do tests and refer to cardiology, and it’s really important to find a cardiologist who can work in concert in taking care of these patients.”
 

Protein Alterations May Disrupt Heart Muscles

In muscular dystrophies, a prevailing theory suggests that alterations to proteins such as dystrophin disrupt structural integrity in both muscle and cardiac cells, he said.

In Duchenne muscular dystrophy (DMD), cardiomyopathy, cardiac conduction abnormalities, or both usually appear in patients by age 10. “It’s important to know that it’s probably present to some degree before that, and it’s not going to get better over time,” he said.

Cardiac problems are universal in DMD by age 18, he said. “Men and boys are living longer, so they have the opportunity to develop the cardiac abnormalities that accrue with time.” Conduction abnormalities typically appear first. “In a lot of these boys, you’ll typically see persistent sinus tachycardia. But they can also develop atrial arrhythmias and bundle branch blocks.”

Sudden cardiac death is responsible for mortality in an estimated 15% patients with DMD. “Very sadly, I lost a patient this way just a few months ago,” Silvestri said.
 

ECGs and Echos Are Recommended

Screening is crucial. “Make sure that patients get that referral and get these tests done,” he said. “You need an ECG and echo by diagnosis or age 6. This is usually repeated annually or biannually, typically by the cardiologist you’re working with.”

The good news is that there’s evidence of survival benefits from treatment with angiotensin-converting enzyme inhibitors for dilated cardiomyopathy. “Some cardiac experts feel treatment with angiotensin receptor blockers (ARBs) is equivalent.”

Most boys will get echocardiograms, he said, “but there’s a lot of evidence showing that cardiac MRI is probably preferable for a number of reasons,” including better visualization. But the need for sedation limits access, he said, and cardiac MRI may not be available at some facilities.
 

Worse Outcomes in Becker Muscular Dystrophy (BMD)

Cardiac involvement is more common and more severe in BMD than in DMD. About 50% of deaths in BMD are attributed to malignant arrhythmias or congestive heart failure, he said.

Screening requirements and treatment options in BMD are similar to those in DMD, with the added option of heart transplantation.

Silvestri cautioned that up to 40% of female carriers of dystrophin mutations can develop cardiac dysfunction similar to that seen in DMD and BMD. Cardiac assessments are recommended every 5 years. “It’s important to genotype Mom,” he said, especially in light of the fact that two thirds of DMD cases may be inherited.

“When I send genetic testing on the mother and find her to be a carrier, I send her to a cardiologist so she has the appropriate screening done,” he said.
 

Pacemakers May Be Considered in Type 1 Myotonic Dystrophy

In type 1 myotonic dystrophy, cardiac conduction abnormalities are seen in two thirds of patients, and sudden cardiac death in up to 30% of patients. “When it is diagnosed, patients do need an ECG at that time, as well as annually,” he said.

Holter monitoring or implantable loop recorders may be recommended, and permanent pacing via an implantable cardioverter-defibrillator might be appropriate.

“Based on the literature to date, the exact timing is not is not clear,” Silvestri said. “The electrophysiologists in my area tend to be very aggressive, thankfully, and treat them fairly soon with pacemakers when we see the first sign of trouble.”

SAVANNAH, GEORGIA — Current disease-modifying therapies for amyotrophic lateral sclerosis (ALS) don’t extend lifespans by much, but several drug options are available, nerve specialists learned.

The glutamate blocker riluzole (Rilutek), which became the first ALS drug to receive US Food and Drug Administration (FDA) approval in 1995, continues to be used, Michael D. Weiss, MD, professor of neurology at University of Washington School of Medicine, Seattle, said in a presentation at the American Association of Neuromuscular & Electrodiagnostic Medicine (AANEM) 2024.

Weiss highlighted a 2012 Cochrane Library review that examined research and found the drug is “reasonably safe” and prolongs median survival by about 2-3 months. “About 12% develop liver disease. It’s pretty rare that we stop the medicine due to liver toxicity.”
 

Earlier Treatment Could Pay Dividends

A recent study “suggests we might be able to get more bang for our buck from riluzole” by initiating treatment earlier, Weiss said.

Researchers tracked 4778 patients with ALS, including 3446 (72.1%) who took riluzole. Those who took the drug survived a median 2 extra months (22.6 vs 20.2 months; P < .001). The data suggested that delaying riluzole initiation by 1 year (from 6 months to 18 months after diagnosis) reduced the median survival by 1.9 months (from 40.1 to 38.2 months).

There’s “a relatively significant additional benefit” to earlier treatment, Weiss said, although patients will vary on whether they think it’s meaningful. As for limitations, “there’s no clear impact on disease progression, and there’s a need for periodic monitoring of liver function profile.” 

He added that there’s an out-of-pocket co-pay. “Even as a generic, it’s not that cheap. Depending on the source, it could cost anywhere from $1800 to $8400 a year.”
 

Edaravone Could Lack Relevant Benefit

No other ALS treatment appeared until 2017, when the FDA approved the novel antioxidant edaravone (Radicava). In 2022, the agency approved an oral suspension version, but a study published that year suggested there may not be a clinically relevant benefit.

The University of Washington, where Weiss works, offered the drug to 144 patients, according to an analysis. Eighty percent of the patients wanted it, but insurers refused to cover it for more than 20%. The average time to treatment with the drug was 28 days after patients said they wanted it.

That’s a “substantial delay,” Weiss said.

The cost is about $171,000 a year, he said, and assistance is limited for underinsured patients.*

Other Options

As Weiss noted, another drug, AMX0035 (Relyvrio), received FDA approval in 2022, but its manufacturer pulled it from the US/Canada market in April 2024 following poor phase 3 trial findings.

In 2023, the FDA approved another drug, the antisense oligonucleotide tofersen (Qalsody), in patients with ALS associated with a mutation in the superoxide dismutase 1 gene. According to the FDA, reductions in plasma neurofilament light concentration were “reasonably likely to predict a clinical benefit in patients.”

Only 1%-2% of patients with ALS fit the criteria to get the drug, Weiss said. He noted other limitations such as the cost ($180,000 a year), the need for lifelong monthly intrathecal injections, and serious neurological side effects in 7% of patients per a 2022 trial.

Weiss disclosed advisory board (Alexion, Ra [now UCB], argenx, Biogen, Mitsubishi Tanabe Pharma, Amylyx), data safety monitoring board (Sanofi, AI), consulting (Cytokinetics, CSL Behring), and speaker (Soleo) relationships.

*Correction, 10/23/2024: This story originally quoted Weiss as saying the maker of edaravone provides no assistance to underinsured patients. Weiss has clarified that he should have said this coverage is “limited.”

LOS ANGELES — Embedding a new discharge order set into electronic health records (EHRs) with a preselected 5-day antibiotic course for children aged 2 years or older diagnosed with acute otitis media (AOM) cut antibiotic duration sharply, according to new data presented at the Infectious Disease Week (IDWeek) 2024 Annual Meeting.

“We were effectively able to cut antibiotic use in half by shortening the duration of treatment,” said lead author Joana Dimo, DO, a Pediatric Infectious Diseases fellow at the University of Colorado Denver/Children’s Hospital Colorado.

In the United States, 80% of children will experience otitis media during their lifetime. Untreated ear infections can lead to symptoms ranging from mild ear discharge to life-threatening conditions such as mastoiditis and intracranial abscesses.
 

Most Cases Resolve Without Antibiotics

Ear infections “are the leading reason for antibiotic prescriptions in kids,” Dimo noted, adding that 24% of all pediatric antibiotic prescriptions are for AOM. Amoxicillin is the preferred first-line treatment. “Research supports that 75% of children get better on their own without antibiotics, and when needed, short courses of just 5 days are safe and effective.”

Antibiotics can cause side effects such as diarrhea and rashes. “Each additional day of antibiotics that are not needed leads to more side effects,” Dimo said, as well as contributing to antibiotic resistance.

Dimo’s team implemented new EHR order sets across the University of Colorado/Children’s Hospital Colorado health network’s four emergency departments and four urgent care centers and included 31,929 patients in the study.

Then they conducted a retrospective review of patients 61 days to 18 years old who entered those settings and had confirmed AOM between January 2019 through December 2023, before and after the April 2021 intervention. The researchers also developed a guideline on managing ear infections to support clinicians as part of the intervention in December 2022.
 

Compliance Grew From 3% to 83%

Dimo said they found very few clinicians in their study had been prescribing according to current guidelines. Their results showed a jump from 3% to 83% in providers prescribing 5-day durations of antibiotics for children aged 2 years or older after their intervention.

The intervention did not lead to increased treatment failures or complications, she added. The team looked for diagnostic codes for mastoiditis, subperiosteal abscess, petrositis, labyrinthitis, meningitis, and intracranial abscess, and “none of our patients” developed any of those complications, Dimo said.

Dimo said the overall rate of prescribing, however, increased. Finding out why prescribing rates remained high throughout the study, before and after their intervention, is a question they are investigating in future work, she said.
 

Cost-Effective and Scalable

“The benefit of this strategy to other institutions is that it’s not labor-intensive. It’s cost-effective, and it can result in dramatic changes in antibiotic use,” Dimo said.

“In the outpatient setting, there’s still a lot of antibiotics being given unnecessarily to children with acute otitis media,” said William Schaffner, MD, infectious disease specialist at Vanderbilt University School of Medicine in Nashville, Tennessee, who was not part of the research. “The American Academy of Pediatrics has been working on that for about a decade — to get pediatricians attuned to when you use them. Most of these episodes of acute otitis media — it’s now well-established — are due to viral infections.”

He said that some physicians may still be defaulting to the longer doses — up to 10 days — that they may have learned in medical school or residency.

“The data would indicate that 5 days of treatment — when treatment is appropriate — is, in the vast majority of instances, sufficient,” Schaffner said.

The researchers “were remarkably successful,” he said, adding that another question is ripe for research. “They still have to get to this issue of whether all of these antibiotic starts were necessary.”

Not knowing whether antibiotic prescriptions in this study were warranted is a limitation of the study, Dimo said, as was not being able to track whether patients presented to institutions outside their own for a return visit or for complications.

She said she thinks one of the reasons for such a sharp increase in compliance was that clinicians in their system routinely use order sets, so using the new order sets easily became part of their workflow.

Dimo and Schaffner reported no relevant financial relationships.

This transcript has been edited for clarity. 

What do we do if we don’t like patients? We take the Hippocratic Oath as young students in Glasgow. We do that just before our graduation ceremony; we hold our hands up and repeat the Hippocratic Oath: “First, do no harm,” and so on.

What happens if we intensely dislike a patient? Is it possible to offer them the very best care? I was thinking back over a long career. I’ve been a cancer doctor for 40 years and I quite like saying that.

I can only think genuinely over a couple of times in which I’ve acted reflexively when a patient has done something awful. The couple of times it happened, it was just terrible racist comments to junior doctors who were with me. Extraordinarily dreadful things such as, “I don’t want to be touched by ...” or something of that sort.

Without really thinking about it, you react as a normal citizen and say, “That’s absolutely awful. Apologize immediately or leave the consultation room, and never ever come back again.” 

I remember that it happened once in Glasgow and once when I was a young professor in Birmingham, and it’s just an automatic gut reaction. The patient got a fright, and I immediately apologized and groveled around. In that relationship, we hold all the power, don’t we? Rather than being gentle about it, I was genuinely angry because of these ridiculous comments. 

Otherwise, I think most of the doctor-patient relationships are predicated on nonromantic love. I think patients want us to love them as one would a son, mother, father, or daughter, because if we do, then we will do better for them and we’ll pull out all the stops. “Placebo” means “I will please.” I think in the vast majority of cases, at least in our National Health Service (NHS), patients come with trust and a sense of wanting to build that relationship. That may be changing, but not for me. 

What about putting the boot on the other foot? What if the patients don’t like us rather than vice versa? As part of our accreditation appraisal process, from time to time we have to take patient surveys as to whether the patients felt that, after they had been seen in a consultation, they were treated with dignity, the quality of information given was appropriate, and they were treated with kindness. 

It’s an excellent exercise. Without bragging about it, patients objectively, according to these measures, appreciate the service that I give. It’s like getting five-star reviews on Trustpilot, or whatever these things are, that allow you to review car salesmen and so on. I have always had five-star reviews across the board. 

That, again, I thought was just a feature of that relationship, of patients wanting to please. These are patients who had been treated, who were in the outpatient department, who were in the midst of battle. Still, the scores are very high. I speak to my colleagues and that’s not uniformly the case. Patients actually do use these feedback forms, I think in a positive rather than negative way, reflecting back on the way that they were treated.

It has caused some of my colleagues to think quite hard about their personal style and approach to patients. That sense of feedback is important. 

What about losing trust? If that’s at the heart of everything that we do, then what would be an objective measure of losing trust? Again, in our healthcare system, it has been exceedingly unusual for a patient to request a second opinion. Now, that’s changing. The government is trying to change it. Leaders of the NHS are trying to change it so that patients feel assured that they can seek second opinions.

Again, in all the years I’ve been a cancer doctor, it has been incredibly infrequent that somebody has sought a second opinion after I’ve said something. That may be a measure of trust. Again, I’ve lived through an NHS in which seeking second opinions was something of a rarity. 

I’d be really interested to see what you think. In your own sphere of healthcare practice, is it possible for us to look after patients that we don’t like, or should we be honest and say, “I don’t like you. Our relationship has broken down. I want you to be seen by a colleague,” or “I want you to be nursed by somebody else”?

Has that happened? Is that something that you think is common or may become more common? What about when trust breaks down the other way? Can you think of instances in which the relationship, for whatever reason, just didn’t work and the patient had to move on because of that loss of trust and what underpinned it? I’d be really interested to know. 

I seek to be informed rather than the other way around. Can we truly look after patients that we don’t like or can we rise above it as Hippocrates might have done? 

Thanks for listening, as always. For the time being, over and out.

What do we do if we don’t like patients? We take the Hippocratic Oath as young students in Glasgow. We do that just before our graduation ceremony; we hold our hands up and repeat the Hippocratic Oath: “First, do no harm,” and so on.

What happens if we intensely dislike a patient? Is it possible to offer them the very best care? I was thinking back over a long career. I’ve been a cancer doctor for 40 years and I quite like saying that.

I can only think genuinely over a couple of times in which I’ve acted reflexively when a patient has done something awful. The couple of times it happened, it was just terrible racist comments to junior doctors who were with me. Extraordinarily dreadful things such as, “I don’t want to be touched by ...” or something of that sort.

Without really thinking about it, you react as a normal citizen and say, “That’s absolutely awful. Apologize immediately or leave the consultation room, and never ever come back again.” 

I remember that it happened once in Glasgow and once when I was a young professor in Birmingham, and it’s just an automatic gut reaction. The patient got a fright, and I immediately apologized and groveled around. In that relationship, we hold all the power, don’t we? Rather than being gentle about it, I was genuinely angry because of these ridiculous comments. 

Otherwise, I think most of the doctor-patient relationships are predicated on nonromantic love. I think patients want us to love them as one would a son, mother, father, or daughter, because if we do, then we will do better for them and we’ll pull out all the stops. “Placebo” means “I will please.” I think in the vast majority of cases, at least in our National Health Service (NHS), patients come with trust and a sense of wanting to build that relationship. That may be changing, but not for me. 

What about putting the boot on the other foot? What if the patients don’t like us rather than vice versa? As part of our accreditation appraisal process, from time to time we have to take patient surveys as to whether the patients felt that, after they had been seen in a consultation, they were treated with dignity, the quality of information given was appropriate, and they were treated with kindness. 

It’s an excellent exercise. Without bragging about it, patients objectively, according to these measures, appreciate the service that I give. It’s like getting five-star reviews on Trustpilot, or whatever these things are, that allow you to review car salesmen and so on. I have always had five-star reviews across the board. 

That, again, I thought was just a feature of that relationship, of patients wanting to please. These are patients who had been treated, who were in the outpatient department, who were in the midst of battle. Still, the scores are very high. I speak to my colleagues and that’s not uniformly the case. Patients actually do use these feedback forms, I think in a positive rather than negative way, reflecting back on the way that they were treated.

It has caused some of my colleagues to think quite hard about their personal style and approach to patients. That sense of feedback is important. 

What about losing trust? If that’s at the heart of everything that we do, then what would be an objective measure of losing trust? Again, in our healthcare system, it has been exceedingly unusual for a patient to request a second opinion. Now, that’s changing. The government is trying to change it. Leaders of the NHS are trying to change it so that patients feel assured that they can seek second opinions.

Again, in all the years I’ve been a cancer doctor, it has been incredibly infrequent that somebody has sought a second opinion after I’ve said something. That may be a measure of trust. Again, I’ve lived through an NHS in which seeking second opinions was something of a rarity. 

I’d be really interested to see what you think. In your own sphere of healthcare practice, is it possible for us to look after patients that we don’t like, or should we be honest and say, “I don’t like you. Our relationship has broken down. I want you to be seen by a colleague,” or “I want you to be nursed by somebody else”?

The American Stroke Association (ASA) has issued a new updated guideline for primary stroke prevention.

The first update in a decade, the 2024 Guideline for the Primary Prevention of Stroke, replaces the 2014 version and is intended to be a resource for clinicians to help them implement a variety of prevention strategies in patients with no previous history of stroke. It aligns with the American Heart Association’s Life’s Essential 8.

“This guideline is an important and timely update from 2014 for multiple reasons. First, there have been groundbreaking clinical trials that have been published with new medications to not only treat the target disease [including] diabetes/obesity and high cholesterol], but also lower the risk of stroke and heart disease,” said chair of the guideline writing group, Cheryl D. Bushnell, MD, MHS, FAHA, and vice chair of the research, Department of Neurology, Wake Forest University School of Medicine, Winston-Salem, North Carolina.

It was published online on October 21 in Stroke.
 

Up to 80% of Strokes Preventable

Estimates show that every year in the United States, more than 500,000 individuals have a first stroke. However, the guideline authors noted that up to 80% of strokes may be preventable. As a result, they called for better primary stroke prevention that includes improved screening and lifestyle changes.

This includes adoption of the Mediterranean diet, which has been shown to significantly reduce stroke risk, especially when supplemented with consumption of nuts and olive oil.

The guideline recommendations also emphasize the need for physical activity, which is “essential” for cardiovascular health and stroke reduction. The authors underscored this point and provided a new recommendation to screen for sedentary behavior and advise patients to avoid inactivity and engage in regular moderate to vigorous physical activity.

Another new recommendation is based on “robust” data that glucagon-like peptide 1 receptor agonists (GLP-1s) significantly improve the management of type 2 diabetes, weight loss, and lower the risk for cardiovascular disease. As a result, guideline authors called for the use of GLP-1s in patients with diabetes and high cardiovascular risk or established cardiovascular disease.

“The glucagon-like peptide receptor agonists have been shown to not only drastically reduce blood sugars in patients with diabetes, but they also lead to significant weight loss in these patients, which has many downstream benefits. Together, this reduces the risk of stroke and other complications of diabetes,” said Bushnell. 

She also noted that another drug class introduced since the 2014 guidelines were published, proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors, have proven to be highly effective in lowering low-density lipoprotein cholesterol. These medications have also been shown to reduce the risk for stroke.
 

At Least Two Meds Needed to Reduce BP

Effective blood pressure (BP) management is crucial for stroke prevention. Randomized controlled trials show that a single antihypertensive medication helps only about 30% of participants reach their BP target.

Most patients only achieve the desired BP target with two to three medications. In line with these data, the committee recommends using at least two antihypertensives for primary stroke prevention in most patients who require BP-lowering medications for hypertension.

In patients with antiphospholipid syndrome or systemic lupus erythematosus and no history of stroke or unprovoked venous thromboembolism, the authors recommended antiplatelet therapy to prevent stroke. They added that patients with antiphospholipid syndrome who have had a prior unprovoked venous thrombosis will likely benefit from vitamin K antagonist therapy (target international normalized ratio, 2-3) over direct oral anticoagulants.
 

Emphasis on Women’s Health

Preventing pregnancy-related stroke is achieved primarily by managing hypertension, the guideline authors noted. They recommended treating verified systolic BP over 160 mm Hg or diastolic BP over 110 mm Hg during pregnancy and up to 6 weeks postpartum to lower the risk for fatal maternal intracerebral hemorrhage.

They noted that adverse pregnancy outcomes are also common and linked to chronic hypertension, which increases stroke risk later in life. Therefore, they recommended screening for these outcomes to assess and manage vascular risk factors. The guideline includes a screening tool to help with this in clinical practice.

Endometriosis, premature ovarian failure (before age 40 years), and early-onset menopause (before age 45 years) are all associated with increased stroke risk. As a result, the guideline authors said screening for all three of these conditions is a “reasonable step in the evaluation and management of vascular risk factors in these individuals to reduce stroke risk.”

Finally, the guideline authors addressed primary stroke prevention in transgender individuals, noting that transgender women undergoing estrogen therapy for gender affirmation are at increased risk. They emphasized that evaluating and modifying risk factors could be beneficial for reducing stroke risk in this patient population.
 

Challenges Lie Ahead

Now that the guideline has been published, the challenge lies in determining how best to implement “its screening recommendations in primary care and other practices when these clinicians are already pushed to see as many patients as possible,” Bushnell said.

Development of screening tools that can be easily incorporated into the clinic visit or the electronic health record, as well as additional personnel to provide counseling, are probably needed to disseminate them, she added. 

Bushnell also emphasized that the guideline includes a strong focus on social determinants of health and related social needs. 

“We worked hard to use inclusive language and to consider populations historically excluded from research. In acknowledging that social determinants of health including access to healthcare, access to education, economic stability, neighborhood and geographic location, and social and community context have a tremendous influence on stroke risk, we describe how these factors are closely tied to the prevalence and management of many medical risks like obesity, hypertension, and diabetes.

“Our recommendations offer practical steps for screening and addressing essential health-related social needs, including access to nutritious food, stable housing, and reliable transportation, within clinical practice. By considering these factors more comprehensively, we believe we can make meaningful strides toward reducing the disparities in stroke risk,” said Bushnell.

A new study provides more evidence that glucagon-like peptide 1 receptor agonists (GLP-1 RAs) used to treat diabetes and obesity could be repurposed for opioid use disorder (OUD) and alcohol use disorder (AUD).

Researchers found that patients with OUD or AUD who were taking semaglutide (Ozempic, Novo Nordisk) or similar medications for diabetes or weight-related conditions had a 40% lower rate of opioid overdose and a 50% lower rate of alcohol intoxication than their peers with OUD or AUD who were not taking these medications.

Their real-world study of more than 1 million adults with a history of OUD or AUD provide “foundational” estimates of the association between glucose-dependent insulinotropic polypeptide (GIP)/GLP-1 RA prescriptions and opioid overdose/alcohol intoxication “and introduce the idea that GLP-1 RA and other related drugs should be investigated as a novel pharmacotherapy treatment option for individuals with OUD or AUD,” wrote the investigators, led by Fares Qeadan, PhD, Parkinson School of Health Sciences and Public Health, Loyola University Chicago, Maywood, Illinois.

The study was published online in the journal Addiction.
 

Protective Effect?

As previously reported by Medscape Medical News, earlier studies have pointed to a link between weight loss drugs and reduced overdose risk in people with OUD and decreased alcohol intake in people with AUD.

Until now, most studies on GLP-1 RAs and GIP agonists like tirzepatide (Mounjaro) to treat substance use disorders consisted of animal studies and small-scale clinical trials, investigators noted.

This new retrospective cohort study analyzed de-identified electronic health record data from the Oracle Health Real-World Data.

Participants, all aged 18 years or older, included 503,747 patients with a history of OUD, of whom 8103 had a GLP-1 RA or GIP prescription, and 817,309 patients with a history of AUD, of whom 5621 had a GLP-1 RA or GIP prescription.

Patients with OUD who were prescribed GLP-1 RAs had a 40% lower rate of opioid overdose than those without such prescriptions (adjusted incidence rate ratio [aIRR], 0.60; 95% CI, 0.43-0.83), the study team found.

In addition, patients with AUD and a GLP-1 RA prescription exhibited a 50% lower rate of alcohol intoxication (aIRR, 0.50; 95% CI, 0.40-0.63).

The protective effect of GLP-1 RA on opioid overdose and alcohol intoxication was maintained across patients with comorbid conditions, such as type 2 diabetes and obesity.

“Future research should focus on prospective clinical trials to validate these findings, explore the underlying mechanisms, and determine the long-term efficacy and safety of GIP/GLP-1 RA medications in diverse populations,” Qeadan and colleagues concluded.

“Additionally, the study highlights the importance of interdisciplinary research in understanding the neurobiological links between metabolic disorders and problematic substance use, potentially leading to more effective treatment strategies within healthcare systems,” they added.
 

Questions Remain

In a statement from the UK nonprofit Science Media Centre, Matt Field, DPhil, professor of psychology, The University of Sheffield, in England, noted that the findings “add to those from other studies, particularly animal research, which suggest that this and similar drugs might one day be prescribed to help people with addiction.”

However, “a note of caution is that the outcomes are very extreme instances of substance intoxication,” added Field, who wasn’t involved in the study.

“Those outcomes are very different from the outcomes used when researchers test new treatments for addiction, in which case we might look at whether the treatment helps people to stop taking the substance altogether (complete abstinence), or if it helps people to reduce the amount of substance they consume, or how often they consume it. Those things could not be measured in this study,” he continued.

“This leaves open the possibility that while Ozempic may — for reasons currently unknown — prevent people from taking so much alcohol or heroin that they overdose and end up in hospital, it may not actually help them to reduce their substance use, or to abstain altogether,” Field said.

The study had no specific funding. The study authors and Field declared no relevant conflicts of interest.

Patients with OUD who were prescribed GLP-1 RAs had a 40% lower rate of opioid overdose than those without such prescriptions (adjusted incidence rate ratio [aIRR], 0.60; 95% CI, 0.43-0.83), the study team found.

In addition, patients with AUD and a GLP-1 RA prescription exhibited a 50% lower rate of alcohol intoxication (aIRR, 0.50; 95% CI, 0.40-0.63).

The protective effect of GLP-1 RA on opioid overdose and alcohol intoxication was maintained across patients with comorbid conditions, such as type 2 diabetes and obesity.

“Future research should focus on prospective clinical trials to validate these findings, explore the underlying mechanisms, and determine the long-term efficacy and safety of GIP/GLP-1 RA medications in diverse populations,” Qeadan and colleagues concluded.

“Additionally, the study highlights the importance of interdisciplinary research in understanding the neurobiological links between metabolic disorders and problematic substance use, potentially leading to more effective treatment strategies within healthcare systems,” they added.
 

Questions Remain

In a statement from the UK nonprofit Science Media Centre, Matt Field, DPhil, professor of psychology, The University of Sheffield, in England, noted that the findings “add to those from other studies, particularly animal research, which suggest that this and similar drugs might one day be prescribed to help people with addiction.”

However, “a note of caution is that the outcomes are very extreme instances of substance intoxication,” added Field, who wasn’t involved in the study.

“Those outcomes are very different from the outcomes used when researchers test new treatments for addiction, in which case we might look at whether the treatment helps people to stop taking the substance altogether (complete abstinence), or if it helps people to reduce the amount of substance they consume, or how often they consume it. Those things could not be measured in this study,” he continued.

“This leaves open the possibility that while Ozempic may — for reasons currently unknown — prevent people from taking so much alcohol or heroin that they overdose and end up in hospital, it may not actually help them to reduce their substance use, or to abstain altogether,” Field said.

The study had no specific funding. The study authors and Field declared no relevant conflicts of interest.

A new study provides more evidence that glucagon-like peptide 1 receptor agonists (GLP-1 RAs) used to treat diabetes and obesity could be repurposed for opioid use disorder (OUD) and alcohol use disorder (AUD).

Researchers found that patients with OUD or AUD who were taking semaglutide (Ozempic, Novo Nordisk) or similar medications for diabetes or weight-related conditions had a 40% lower rate of opioid overdose and a 50% lower rate of alcohol intoxication than their peers with OUD or AUD who were not taking these medications.

Their real-world study of more than 1 million adults with a history of OUD or AUD provide “foundational” estimates of the association between glucose-dependent insulinotropic polypeptide (GIP)/GLP-1 RA prescriptions and opioid overdose/alcohol intoxication “and introduce the idea that GLP-1 RA and other related drugs should be investigated as a novel pharmacotherapy treatment option for individuals with OUD or AUD,” wrote the investigators, led by Fares Qeadan, PhD, Parkinson School of Health Sciences and Public Health, Loyola University Chicago, Maywood, Illinois.

The study was published online in the journal Addiction.
 

Protective Effect?

As previously reported by Medscape Medical News, earlier studies have pointed to a link between weight loss drugs and reduced overdose risk in people with OUD and decreased alcohol intake in people with AUD.

Until now, most studies on GLP-1 RAs and GIP agonists like tirzepatide (Mounjaro) to treat substance use disorders consisted of animal studies and small-scale clinical trials, investigators noted.

This new retrospective cohort study analyzed de-identified electronic health record data from the Oracle Health Real-World Data.

Participants, all aged 18 years or older, included 503,747 patients with a history of OUD, of whom 8103 had a GLP-1 RA or GIP prescription, and 817,309 patients with a history of AUD, of whom 5621 had a GLP-1 RA or GIP prescription.

TOPLINE:

In healthy young adults, a single 30-minute bout of outdoor aerobic exercise significantly reduces fasting and 1-hour glucose levels during an oral glucose tolerance test (OGTT) the next day and improves insulin sensitivity.

METHODOLOGY:

• Recent studies have identified 1-hour post-load glucose concentration during an OGTT as a specific and early predictor of diabetes, and exercise has long been known for its metabolic benefits in people with and without diabetes.
• The researchers investigated the effect of a single bout of aerobic exercise on 1-hour post-load glucose levels during an OGTT in 32 young, healthy, normal-weight or marginally overweight individuals (mean age, 35 years; 14 women and 18 men) with a sedentary or moderately active lifestyle.
• The participants underwent an initial OGTT after at least 4 days of physical inactivity, followed by a second OGTT the day after a single 30-minute bout of aerobic exercise.
• The exercise session consisted of a light jog for 30 minutes, monitored using a metabolic holter to quantify energy expenditure and exercise intensity. The participants did not undertake any exercise outside the lab sessions.
• Blood glucose levels were measured, and insulin sensitivity and secretion were estimated using surrogate indices derived from OGTT glucose and insulin assays, including the Matsuda index, oral glucose insulin sensitivity (OGIS) index, and quantitative insulin sensitivity check index, as well as the homeostasis model assessment (HOMA) of insulin resistance and of beta-cell function (HOMA-B).

TAKEAWAY:

•  
• Postexercise insulin levels also were significantly lower 1 hour after glucose load, decreasing from 57.4 IU/mL at baseline to 43.5 IU/mL the day after exercise (P = .01).
• Insulin sensitivity improved significantly after exercise, as indicated by increases in the Matsuda index (P = .02) and OGIS index (P = .04), along with a reduction in insulin resistance (P = .04).
• The study found a trend toward increased beta-cell function the day after an exercise bout, as indicated by a nonsignificant increase in HOMA-B from 144.7 at baseline to 167.1 after exercise.

IN PRACTICE:

“Improvement in 1-hour post-load plasma glucose following a single session of aerobic physical activity suggests that exercise could have a direct effect on T2D [type 2 diabetes] risk and cardiovascular risk,” the authors wrote.

SOURCE:

The study was led by Simona Moffa, Fondazione Policlinico Universitario Agostino Gemelli IRCCS, Rome, and Gian Pio Sorice, Università Degli Studi di Bari “Aldo Moro,” Bari, Italy. It was published online in the Journal of Endocrinological Investigation.

LIMITATIONS:

The study had a limited sample size, which may affect the generalizability of the findings. C-peptide levels, which could have provided additional insights into insulin secretion, were not assessed in the study.

DISCLOSURES:

The study was supported by grants from Università Cattolica del Sacro Cuore. The authors declared no conflicts of interest.
