Calcium and CV Risk: Are Supplements and Vitamin D to Blame?
This transcript has been edited for clarity.
Tricia Ward: Hi. I’m Tricia Ward, from theheart.org/Medscape Cardiology. I’m joined today by Dr Matthew Budoff. He is professor of medicine at UCLA and the endowed chair of preventive cardiology at the Lundquist Institute. Welcome, Dr Budoff.
Matthew J. Budoff, MD: Thank you.
Dietary Calcium vs Coronary Calcium
Ms. Ward: The reason I wanted to talk to you today is because there have been some recent studies linking calcium supplements to an increased risk for cardiovascular disease. I’m old enough to remember when we used to tell people that dietary calcium and coronary calcium weren’t connected and weren’t the same. Were we wrong?
Dr. Budoff: I think there’s a large amount of mixed data out there still. The US Preventive Services Task Force looked into this a number of years ago and said there’s no association between calcium supplementation and increased risk for cardiovascular disease.
As you mentioned, there are a couple of newer studies that point us toward a relationship. I think that we still have a little bit of a mixed bag, but we need to dive a little deeper into that to figure out what’s going on.
Ms. Ward: Does it appear to be connected to calcium in the form of supplements vs calcium from foods?
Dr. Budoff: We looked very carefully at dietary calcium in the MESA study, the multiethnic study of atherosclerosis. There is no relationship between dietary calcium intake and coronary calcium or cardiovascular events. We’re talking mostly about supplements now when we talk about this increased risk that we’re seeing.
Does Vitamin D Exacerbate Risk?
Ms. Ward: Because it’s seen with supplements, is that likely because that’s a much higher concentration of calcium coming in or do you think it’s something inherent in its being in the form of a supplement?
Dr. Budoff: I think there are two things. One, it’s definitely a higher concentration all at once. You get many more milligrams at a time when you take a supplement than if you had a high-calcium food or drink.
Also, most supplements have vitamin D as well. I think vitamin D and calcium work synergistically. When you give them both together simultaneously, I think that may have more of a potentiating effect that might exacerbate any potential risk.
Ms. Ward: Is there any reason to think there might be a difference in type of calcium supplement? I always think of the chalky tablet form vs calcium chews.
Dr. Budoff: I’m not aware of a difference in the supplement type. I think the vitamin D issue is a big problem because we all have patients who take thousands of units of vitamin D — just crazy numbers. People advocate really high numbers and that stays in the system.
Personally, I think part of the explanation is that with very high levels of vitamin D on top of calcium supplementation, you now absorb it better. You now get it into the bone, but maybe also into the coronary arteries. If you’re very high in vitamin D and then are taking a large calcium supplement, it might be the calcium/vitamin D combination that’s giving us some trouble. I think people on vitamin D supplements really need to watch their levels and not get supratherapeutic.
Ms. Ward: With the vitamin D?
Dr. Budoff: With the vitamin D.
Diabetes and Renal Function
Ms. Ward: In some of the studies, there seems to be a higher risk in patients with diabetes. Is there any reason why that would be?
Dr. Budoff: I can’t think of a reason exactly why with diabetes per se, except for renal disease. Patients with diabetes have more intrinsic renal disease, proteinuria, and even a reduced eGFR. We’ve seen that the kidney is very strongly tied to this. We have a very strong relationship, in work I’ve done a decade ago now, showing that calcium supplementation (in the form of phosphate binders) in patients on dialysis or with advanced renal disease is linked to much higher coronary calcium progression.
We did prospective, randomized trials showing that calcium intake as binders to reduce phosphorus led to more coronary calcium. We always thought that was just relegated to the renal population, and there might be an overlap here with the diabetes and more renal disease. I have a feeling that it has to do with more of that. It might be regulation of parathyroid hormone as well, which might be more abnormal in patients with diabetes.
Avoid Supratherapeutic Vitamin D Levels
Ms. Ward:: What are you telling your patients?
Dr. Budoff: I tell patients with normal kidney function that the bone will modulate 99.9% of the calcium uptake. If they have osteopenia or osteoporosis, regardless of their calcium score, I’m very comfortable putting them on supplements.
I’m a little more cautious with the vitamin D levels, and I keep an eye on that and regulate how much vitamin D they get based on their levels. I get them into the normal range, but I don’t want them supratherapeutic. You can even follow their calcium score. Again, we’ve shown that if you’re taking too much calcium, your calcium score will go up. I can just check it again in a couple of years to make sure that it’s safe.
Ms. Ward:: In terms of vitamin D levels, when you’re saying “supratherapeutic,” what levels do you consider a safe amount to take?
Dr. Budoff: I’d like them under 100 ng/mL as far as their upper level. Normal is around 70 ng/mL at most labs. I try to keep them in the normal range. I don’t even want them to be high-normal if I’m going to be concomitantly giving them calcium supplements. Of course, if they have renal insufficiency, then I’m much more cautious. We’ve even seen calcium supplements raise the serum calcium, which you never see with dietary calcium. That’s another potential proof that it might be too much too fast.
For renal patients, even in mild renal insufficiency, maybe even in diabetes where we’ve seen a signal, maybe aim lower in the amount of calcium supplementation if diet is insufficient, and aim a little lower in vitamin D targets, and I think you’ll be in a safer place.
Ms. Ward: Is there anything else you want to add?
Dr. Budoff: The evidence is still evolving. I’d say that it’s interesting and maybe a little frustrating that we don’t have a final answer on all of this. I would stay tuned for more data because we’re looking at many of the epidemiologic studies to try to see what happens in the real world, with both dietary intake of calcium and calcium supplementation.
Ms. Ward: Thank you very much for joining me today.
Dr. Budoff: It’s a pleasure. Thanks for having me.

Another Reason to Control Lp(a): To Protect the Kidneys Too
LYON, FRANCE — High levels of lipoprotein(a) [Lp(a)] in the blood are associated with a significantly increased risk for chronic kidney disease, report investigators who are studying the link in a two-part study of more than 100,000 people.
There is already genetic evidence showing that Lp(a) can cause cardiovascular conditions, including myocardial infarction, aortic valve stenosis, peripheral artery disease, and ischemic stroke.
Now, researchers presenting at the European Atherosclerosis Society (EAS) 2024 Congress are adding new organs – the kidneys – to the list of those that can be damaged by elevated Lp(a).
“This is very important,” said lead investigator Anne Langsted, MD, PhD, DMSc, from the Department of Clinical Biochemistry at the Rigshospitalet in Denmark. And “hopefully, we’ll have a treatment for Lp(a) on the market very soon. Until then, I think individuals who have kidney disease would benefit a lot from reducing other risk factors, if they also have high levels” of Lp(a).
Using data gathered from the Copenhagen General Population Study, the study involved 108,439 individuals who had a range of tests including estimated glomerular filtration rate (eGFR), plasma Lp(a) levels, and LPA genotyping. The patients were then linked to a series of national registries to study outcomes.
The researchers conducted two separate analyses: an observational study of Lp(a) levels in 70,040 individuals and a Mendelian randomization study of LPA kringle IV–type 2 domain repeats in 106,624 individuals. The number of those repeats is inversely associated with median Lp(a) plasma levels.
The observational study showed that eGFR decreased with increasing median plasma Lp(a) levels; the Mendelian randomization study indicated that eGFR decreased KIV-2 repeat numbers dropped.
Across both parts of the study, it was found that each 50 mg/dL increase in plasma Lp(a) levels was associated with an increased risk of at least 25% for chronic kidney disease.
Lp(a) and Chronic Kidney Disease
When high plasma levels of Lp(a) have been spotted before in patients with kidney disease, “we’ve kind of assumed that it was probably the kidney disease that caused the higher levels,” Dr. Langsted said. But her team hypothesized that the opposite was at play and that Lp(a) levels are genetically determined, and increased plasma Lp(a) levels may be causally associated with rising risk for chronic kidney disease.
Gerald F. Watts, MD, PhD, DSc, Winthrop Professor of cardiometabolic and internal medicine at the University of Western Australia in Perth, and co-chair of the study, said in an interview that “although Mendelian randomization is a technique that allows you to infer causality, it’s probably a little bit more complex than that in reality,” adding that there is likely a bidirectional relationship between Lp(a) and chronic kidney disease.
Having increased Lp(a) levels on their own is not sufficient to trigger chronic kidney disease. “You probably need another event and then you get into a vicious cycle,” Dr. Watts said.
The mechanism linking Lp(a) with chronic kidney disease remains unclear, but Dr. Watts explained that the lipoprotein probably damages the renal tubes when it is reabsorbed after it dissociates from low-density lipoprotein cholesterol.
The next step will be to identify the people who are most susceptible to this and figure out what treatment might help. Dr. Watts suggested that gene silencing, in which Lp(a) is “completely obliterated,” will lead to an improvement in renal function.

Investigational Male Contraceptive Suppresses Sperm Rapidly
BOSTON — An investigational male contraceptive gel suppresses sperm more rapidly than previous products in development, new data suggested.
The product, 8 mg segesterone acetate (Nestorone) combined with 74 mg testosterone (“NesT”) is a gel that a man applies daily to both shoulders. The progesterone blocks spermatogenesis, and the testosterone restores blood levels to maintain sexual function. It is under development by the National Institute of Child Health and Human Development (NICHD) in collaboration with the Population Council, the Los Angeles Biomedical Research Institute, and the University of Washington School of Medicine.
Currently, the only available male contraceptives are vasectomy, which isn’t easily reversible, and condoms, which have a high failure rate. Previous attempts to develop a “male pill” have been unsuccessful for a variety of reasons, but so far, this product appears effective and safe, Diana Blithe, PhD, chief of the Contraceptive Development Program at NICHD, said at a press briefing held on June 2, 2024, during the annual meeting of the Endocrine Society.
“It’s been a long time coming. … Men need and want more contraceptive options such as an effective reversible method,” she told this news organization.
New phase 2b data show that among 222 couples in which the man initially had normal (> 15 million/mL) sperm counts, the median time to suppression (< 1 million/mL) was less than 8 weeks with NesT compared with 9-15 weeks seen in previous trials of injected male hormonal contraceptives. Nearly all (86%) had achieved suppression by 15 weeks.
After two consecutive counts of < 1 million/mL, the couples entered the trial’s ongoing 2-year efficacy phase. There have been no major safety concerns thus far, but “we need more data,” Dr. Blithe noted.
Asked to comment, session moderator Frances Hayes, MBBCh, associate clinical chief of the Division of Reproductive Endocrinology at Massachusetts General Hospital, Boston, said, “certainly, I think it’s a big advance on what we have so far. … I think it’s showing great promise.”
Dr. Hayes did caution, though, that “with real-world use, daily application of a gel might be a bit more challenging than taking an injection…an injection is more consistent. With a gel, patients might forget or shower it off. But I don’t think 1 day of interruption would be a significant thing.”
Transference of the topical to a partner or a child is another potential concern, Dr. Hayes noted, although this is true of current testosterone gel products as well. During the briefing, Dr. Blithe said that this issue is why the product is recommended to be placed on the upper arms rather than the abdomen or another spot more likely to come into contact with another person. Also, in the trial, men were instructed to wear shirts during intercourse.
Regarding the rapidity of sperm suppression, Dr. Hayes said, “It’s surprising. It looks great as a reversible contraceptive. … Normally, you think of the life cycle of the sperm being about 72 days. So to see 50% suppression by 8 weeks, and then 85%-90% by 15 weeks, that’s very rapid. It may be that the progesterone that they’re using is very potent. Progestins can have some negative effects on lipids and mood. We didn’t really see the safety data in this presentation. So that will be interesting to see.”
During the briefing, Dr. Blithe said that the phase 2b trial is expected to finish by the end of this year, and in the meantime, the researchers are communicating with the US Food and Drug Administration about the design of a phase 3 trial because this is an unprecedented area. “They don’t have guidelines yet. They’ll need to develop them first.”

BOSTON — An investigational male contraceptive gel suppresses sperm more rapidly than previous products in development, new data suggested.
The product, 8 mg segesterone acetate (Nestorone) combined with 74 mg testosterone (“NesT”) is a gel that a man applies daily to both shoulders. The progesterone blocks spermatogenesis, and the testosterone restores blood levels to maintain sexual function. It is under development by the National Institute of Child Health and Human Development (NICHD) in collaboration with the Population Council, the Los Angeles Biomedical Research Institute, and the University of Washington School of Medicine.
Currently, the only available male contraceptives are vasectomy, which isn’t easily reversible, and condoms, which have a high failure rate. Previous attempts to develop a “male pill” have been unsuccessful for a variety of reasons, but so far, this product appears effective and safe, Diana Blithe, PhD, chief of the Contraceptive Development Program at NICHD, said at a press briefing held on June 2, 2024, during the annual meeting of the Endocrine Society.
“It’s been a long time coming. … Men need and want more contraceptive options such as an effective reversible method,” she told this news organization.
New phase 2b data show that among 222 couples in which the man initially had normal (> 15 million/mL) sperm counts, the median time to suppression (< 1 million/mL) was less than 8 weeks with NesT compared with 9-15 weeks seen in previous trials of injected male hormonal contraceptives. Nearly all (86%) had achieved suppression by 15 weeks.
After two consecutive counts of < 1 million/mL, the couples entered the trial’s ongoing 2-year efficacy phase. There have been no major safety concerns thus far, but “we need more data,” Dr. Blithe noted.
Asked to comment, session moderator Frances Hayes, MBBCh, associate clinical chief of the Division of Reproductive Endocrinology at Massachusetts General Hospital, Boston, said, “certainly, I think it’s a big advance on what we have so far. … I think it’s showing great promise.”
Dr. Hayes did caution, though, that “with real-world use, daily application of a gel might be a bit more challenging than taking an injection…an injection is more consistent. With a gel, patients might forget or shower it off. But I don’t think 1 day of interruption would be a significant thing.”
Transference of the topical to a partner or a child is another potential concern, Dr. Hayes noted, although this is true of current testosterone gel products as well. During the briefing, Dr. Blithe said that this issue is why the product is recommended to be placed on the upper arms rather than the abdomen or another spot more likely to come into contact with another person. Also, in the trial, men were instructed to wear shirts during intercourse.
Regarding the rapidity of sperm suppression, Dr. Hayes said, “It’s surprising. It looks great as a reversible contraceptive. … Normally, you think of the life cycle of the sperm being about 72 days. So to see 50% suppression by 8 weeks, and then 85%-90% by 15 weeks, that’s very rapid. It may be that the progesterone that they’re using is very potent. Progestins can have some negative effects on lipids and mood. We didn’t really see the safety data in this presentation. So that will be interesting to see.”

Eating More Vegetables Improves Glucose Tolerance
TOPLINE:
A diet rich in green, leafy, cruciferous, and colorful vegetables may improve glucose tolerance and insulin sensitivity, whereas a high intake of potato fries or chips may worsen these outcomes, an Australian study shows.
METHODOLOGY:
- Researchers assessed the association between the intake of vegetables and potatoes with markers of type 2 diabetes (T2D) in 8009 participants (median age, 52 years; 55% women) from the Australian Diabetes, Obesity, and Lifestyle Study.
- A self-administered 74-item food frequency questionnaire was used to assess participants’ eating habits over 12 months prior to baseline.
- Participants were categorized into four quartiles of vegetable intake, from the highest intake (Q4) to the lowest intake (Q1).
- The association between vegetable intake and various metabolic markers such as fasting plasma glucose (FPG), 2-hour post-load plasma glucose, updated homeostasis model assessment of beta cell function (HOMA2-%beta), HOMA2 of insulin sensitivity (HOMA2-%S), and fasting insulin were evaluated over a 12-year follow-up period.
TAKEAWAY:
- The post-load glucose was 3% lower in participants in the highest vs lowest quartile of total vegetable intake (ratio of means [RoM], 0.97; 95% CI, 0.96-0.99).
- Post-load glucose was 4% lower (RoM, 0.96; 95% CI, 0.95-0.98), HOMA2-%beta was 3% lower (RoM, 0.97; 95% CI, 0.96-0.99), and serum insulin was 5% lower (RoM, 0.95; 95% CI, 0.93-0.98) in those in the highest vs lowest quartile of green leafy vegetable intake.
- Those in the highest vs lowest quartile of potato fries or chips intake had 1% higher FPG, 3% higher HOMA2-%beta, and 8% higher serum insulin but 6% lower HOMA2-%S, revealing a negative impact on glucose tolerance and insulin sensitivity.
- The risk for T2D over 12 years was 26% and 25% lower among those in the highest and moderate quartiles of cruciferous vegetable intake, respectively, than among those in the lowest quartile of cruciferous vegetable intake.
IN PRACTICE:
The authors wrote that their study “sheds light on the physiological alterations in insulin regulation and glucose tolerance resulting from higher vegetable and subgroups of vegetable intake and supports the notion that vegetable subgroups may act differently in regulating insulin and blood glucose levels.”
SOURCE:
The study was led by Pratik Pokharel, MPH, Nutrition & Health Innovation Research Institute, School of Medical and Health Sciences, Edith Cowan University, Perth, Australia, and was published online in The Journal of Clinical Endocrinology & Metabolism.
LIMITATIONS:
The study’s observational nature precluded the inference of causality. Potential measurement errors in dietary exposures and recall bias linked to the food frequency questionnaire could have affected the findings. The overrepresentation of participants from higher education and socioeconomic subgroups and loss to follow-up could limit the generalizability of the findings.
DISCLOSURES:
The study was funded by the National Health and Medical Research Council, National Heart Foundation of Australia, and Royal Perth Hospital Medical Research Foundation. Several authors reported receiving grants from various sources during the conduct of this study. The other authors reported no conflicts of interest.

Frontal Fibrosing Alopecia: Study Finds Oral Contraceptive Use Modulates Risk In Women with Genetic Variant
TOPLINE:
Investigators found that
.METHODOLOGY:
- OC use has been considered a possible factor behind the increased incidence of FFA because it was first documented in 1994, and a recent genome-wide association study of FFA identified a signal for an association with a variant in CYP1B1.
- The same researchers conducted a gene-environment interaction study with a case-control design involving 489 White female patients (mean age, 65.8 years) with FFA and 34,254 controls, matched for age and genetic ancestry.
- Data were collected from July 2015 to September 2017 and analyzed from October 2022 to December 2023.
- The study aimed to investigate the modulatory effect of OC use on the CYP1B1 variant’s impact on FFA risk, using logistic regression models for analysis.
TAKEAWAY:
- The use of OCs was associated with a 1.9 times greater risk for FFA in individuals with the specific CYP1B1 genetic variant, but there was no association among those with no history of OC use.
- The study suggests a significant gene-environment interaction, indicating that OC use may influence FFA risk in genetically predisposed individuals.
IN PRACTICE:
“This gene-environment interaction analysis suggests that the protective effect of the CYPIB1 missense variant on FFA risk might be mediated by exposure” to OCs, the authors wrote. The study, they added, “underscores the importance of considering genetic predispositions and environmental factors, such as oral contraceptive use, in understanding and managing frontal fibrosing alopecia.”
SOURCE:
Tuntas Rayinda, MD, MSc, PhD, of St. John’s Institute of Dermatology, King’s College London, led the study, which was published online May 29, 2024, in JAMA Dermatology.
LIMITATIONS:
The study’s reliance on self-reported OC use may have introduced recall and differences in ascertainment of OC use between patient and control groups and could have affected the study’s findings. The study also did not collect information on the type of OC used, which could have influenced the observed interaction.
DISCLOSURES:
The study was supported by the British Skin Foundation Young Investigator Award. One investigator reported being a subinvestigator on an alopecia areata study funded by Pfizer. No other disclosures were reported.
This article was created using several editorial tools, including AI, as part of the process. Human editors reviewed this content before publication.

USPSTF Recommends Exercise To Prevent Falls in Older Adults
Exercise interventions are recommended to help prevent falls and fall-related morbidity in community-dwelling adults aged 65 years and older who are at increased risk of falls, according to a new recommendation statement from the U.S. Preventive Services Task Force (USPSTF) (JAMA. 2024 Jun 4. doi: 10.1001/jama.2024.8481).
Falls remain the leading cause of injury-related morbidity and mortality among older adults in the United States, with approximately 27% of community-dwelling individuals aged 65 years and older reporting at least one fall in the past year, wrote lead author Wanda K. Nicholson, MD, of George Washington University, Washington, and colleagues.
The task force concluded with moderate certainty that exercise interventions yielded a moderate benefit in fall reduction among older adults at risk (grade B recommendation).
The decision to offer multifactorial fall prevention interventions to older adults at risk for falls should be individualized based on assessment of potential risks and benefits of these interventions, including circumstances of prior falls, presence of comorbid medical conditions, and the patient’s values and preferences (grade C recommendation), the authors wrote.
The exercise intervention could include individual or group activity, although most of the studies in the systematic review involved group exercise, the authors noted.
The recommendation was based on data from a systematic evidence review published in JAMA (2024 Jun 4. doi: 10.1001/jama.2024.4166). The task force reviewed data from 83 randomized trials published between January 1, 2016, and May 8, 2023, deemed fair to good quality that examined six types of fall prevention interventions in a total of 48,839 individuals. Of these, 28 studies involved multifactorial interventions and 27 involved exercise interventions.
Overall, multifactorial interventions and exercise interventions were associated with a significant reduction in falls (incidence rate ratio 0.84 and 0.85, respectively).
Exercise interventions were significantly associated with reduced individual risk of one or more falls and injurious falls, but not with reduced individual risk of injurious falls. However, multifactorial interventions were not significantly associated with reductions in risk of one or more falls, injurious falls, fall-related fractures, individual risk of injurious falls, or individual risk of fall-related fractures.
Although teasing out the specific exercise components that are most effective for fall prevention is challenging, the most commonly studied components associated with reduced risk of falls included gait training, balance training, and functional training, followed by strength and resistance training, the task force noted.
Duration of exercise interventions in the reviewed studies ranged from 2 to 30 months and the most common frequency of sessions was 2 to 3 per week.
Based on these findings, the task force found that exercise had the most consistent benefits for reduced risk across several fall-related outcomes. Although individuals in the studies of multifactorial interventions were at increased risk for falls, the multistep process of interventions to address an individual’s multiple risk factors limited their effectiveness, in part because of logistical challenges and inconsistent adherence, the authors wrote.
The results of the review were limited by several factors, including the focus on studies with a primary or secondary aim of fall prevention, the fact that the recommendation does not apply to many subgroups of older adults, and the lack of data on health outcomes unrelated to falls that were associated with the interventions, the authors noted.
The new recommendation is consistent with and replaces the 2018 USPSTF recommendation on interventions for fall prevention in community-dwelling older adults, but without the recommendation against vitamin D supplementation as a fall prevention intervention. The new recommendation does not address vitamin D use; evidence will be examined in a separate recommendation, the task force wrote.
How to Get Older Adults Moving
“The biggest obstacle to exercise is patient inertia and choice to engage in other sedentary activities,” David B. Reuben, MD, and David A. Ganz, MD, both of the University of California, Los Angeles, wrote in an accompanying editorial (JAMA. 2024 Jun 4. doi: 10.1001/jama.2024.9063).
“Given the demonstrated benefits of exercise for cardiovascular disease, cognitive function, and favorable associations with all-cause, cardiovascular, and cancer mortality, specific fall prevention exercise recommendations need to be considered in the context of universal exercise recommendations, including aerobic and muscle strengthening exercise,” the authors wrote. However, maintaining regular exercise is a challenge for many older adults, and more research is needed on factors that drive exercise initiation and adherence in this population, they said.
Multifactorial fall assessments in particular take time, and more fall prevention programs are needed that include multifactorial assessments and interventions, the editorialists said. “Even if primary care clinicians faithfully implement the USPSTF recommendations, a significant reduction in falls and their resulting injuries is still far off,” in part, because of the need for more programs and policies, and the need to improve access to exercise programs and provide insurance coverage for them, they noted.
“Above all, older persons need to be active participants in exercise and reduction of risk factors for falls,” the editorialists concluded.
The research for the recommendation was funded by the Agency for Healthcare Research and Quality (AHRQ). The authors had no financial conflicts to disclose. Dr. Ganz disclosed serving as an author of the 2022 World Guidelines for Falls Prevention and Management for Older Adults.

“The biggest obstacle to exercise is patient inertia and choice to engage in other sedentary activities,” David B. Reuben, MD, and David A. Ganz, MD, both of the University of California, Los Angeles, wrote in an accompanying editorial (JAMA. 2024 Jun 4. doi: 10.1001/jama.2024.9063).
“Given the demonstrated benefits of exercise for cardiovascular disease, cognitive function, and favorable associations with all-cause, cardiovascular, and cancer mortality, specific fall prevention exercise recommendations need to be considered in the context of universal exercise recommendations, including aerobic and muscle strengthening exercise,” the authors wrote. However, maintaining regular exercise is a challenge for many older adults, and more research is needed on factors that drive exercise initiation and adherence in this population, they said.
Multifactorial fall assessments in particular take time, and more fall prevention programs are needed that include multifactorial assessments and interventions, the editorialists said. “Even if primary care clinicians faithfully implement the USPSTF recommendations, a significant reduction in falls and their resulting injuries is still far off,” in part, because of the need for more programs and policies, and the need to improve access to exercise programs and provide insurance coverage for them, they noted.
“Above all, older persons need to be active participants in exercise and reduction of risk factors for falls,” the editorialists concluded.
The research for the recommendation was funded by the Agency for Healthcare Research and Quality (AHRQ). The authors had no financial conflicts to disclose. Dr. Ganz disclosed serving as an author of the 2022 World Guidelines for Falls Prevention and Management for Older Adults.
Exercise interventions are recommended to help prevent falls and fall-related morbidity in community-dwelling adults aged 65 years and older who are at increased risk of falls, according to a new recommendation statement from the U.S. Preventive Services Task Force (USPSTF) (JAMA. 2024 Jun 4. doi: 10.1001/jama.2024.8481).
Falls remain the leading cause of injury-related morbidity and mortality among older adults in the United States, with approximately 27% of community-dwelling individuals aged 65 years and older reporting at least one fall in the past year, wrote lead author Wanda K. Nicholson, MD, of George Washington University, Washington, and colleagues.
The task force concluded with moderate certainty that exercise interventions yielded a moderate benefit in fall reduction among older adults at risk (grade B recommendation).
The decision to offer multifactorial fall prevention interventions to older adults at risk for falls should be individualized based on assessment of potential risks and benefits of these interventions, including circumstances of prior falls, presence of comorbid medical conditions, and the patient’s values and preferences (grade C recommendation), the authors wrote.
The exercise intervention could include individual or group activity, although most of the studies in the systematic review involved group exercise, the authors noted.
The recommendation was based on data from a systematic evidence review published in JAMA (2024 Jun 4. doi: 10.1001/jama.2024.4166). The task force reviewed data from 83 randomized trials published between January 1, 2016, and May 8, 2023, deemed fair to good quality that examined six types of fall prevention interventions in a total of 48,839 individuals. Of these, 28 studies involved multifactorial interventions and 27 involved exercise interventions.
Overall, multifactorial interventions and exercise interventions were associated with a significant reduction in falls (incidence rate ratio 0.84 and 0.85, respectively).
Exercise interventions were significantly associated with reduced individual risk of one or more falls and injurious falls, but not with reduced individual risk of injurious falls. However, multifactorial interventions were not significantly associated with reductions in risk of one or more falls, injurious falls, fall-related fractures, individual risk of injurious falls, or individual risk of fall-related fractures.
Although teasing out the specific exercise components that are most effective for fall prevention is challenging, the most commonly studied components associated with reduced risk of falls included gait training, balance training, and functional training, followed by strength and resistance training, the task force noted.
Duration of exercise interventions in the reviewed studies ranged from 2 to 30 months and the most common frequency of sessions was 2 to 3 per week.
Based on these findings, the task force found that exercise had the most consistent benefits for reduced risk across several fall-related outcomes. Although individuals in the studies of multifactorial interventions were at increased risk for falls, the multistep process of interventions to address an individual’s multiple risk factors limited their effectiveness, in part because of logistical challenges and inconsistent adherence, the authors wrote.
The results of the review were limited by several factors, including the focus on studies with a primary or secondary aim of fall prevention, the fact that the recommendation does not apply to many subgroups of older adults, and the lack of data on health outcomes unrelated to falls that were associated with the interventions, the authors noted.
The new recommendation is consistent with and replaces the 2018 USPSTF recommendation on interventions for fall prevention in community-dwelling older adults, but without the recommendation against vitamin D supplementation as a fall prevention intervention. The new recommendation does not address vitamin D use; evidence will be examined in a separate recommendation, the task force wrote.

How Can Patients With Diabetes and Obesity Lose Weight?
BERLIN — What is the best way to help patients with diabetes, heart problems, and obesity lose weight and improve their outcomes? Is it exercise or medication (such as glucagon-like peptide 1 or gastric inhibitory polypeptide receptor agonists)? This was the focus of a “Battle of Experts” at the 2024 Diabetes Congress in Berlin.
Benefits of Exercise
“Exercise is ‘omnipotent,’ ” said Christine Joisten, MD, general, sports, and nutrition physician at the Sports University in Cologne, Germany. She pointed out that exercise not only helps with weight loss but also improves overall fitness, body composition, eating habits, cardiometabolic health, and quality of life, listing the benefits of exercise.
In a conversation with this news organization, Stephan Kress, MD, a diabetologist at Vinzentius Hospital in Landau, Germany, and first chair of the German Diabetes Society’s Diabetes, Sports, and Exercise Working Group, referred to a study by Pedersen et al. that examined the effect of exercise on 26 conditions. It indicated that exercise had moderate to strong positive effects on disease progression. The benefits of exercise extended beyond metabolic, cardiological, pneumological, and musculoskeletal diseases to neurological and psychiatric conditions.
The so-called myokines, which are “good” cytokines released by muscles, could play a role in this process, according to a presentation by study author Bente Klarlund Pedersen, MD, of Rigshospitalet in Copenhagen, Denmark.
For example, exercise could elevate mood in patients with depression and reduce inflammation in individuals with chronic inflammatory diseases, said Dr. Kress. Many patients, including those with diabetes, could benefit from physical activity even if their A1c levels do not decrease as desired.
Exercise As a Snack
Fat loss can be achieved with prolonged activity or with “short and intense” sessions if followed by refraining from eating immediately afterward, Dr. Joisten explained during the expert battle at the Diabetes Congress.
Different recommendations exist regarding how much exercise is necessary. According to the World Health Organization’s (WHO) recommendation, “Every step counts.” “As sports physicians, we consider physical activity to be any form of energy expenditure achieved through muscle activity,” said Dr. Joisten.
This means that even occasional standing up, walking around, climbing stairs, and everyday activities are a start. They help motivate stigmatized, discouraged patients with obesity. Dr. Joisten highlighted a clear advantage of exercise over the “weight loss injection.” “You can promise your patients that when they start or resume physical activity, they will experience the greatest increase in fitness and health right from the start.”
Just 500 more steps per day can decrease cardiovascular mortality by 7%, while a daily increase of 1000 steps reduces overall mortality by 15%, according to a recent meta-analysis. For movement in a confined space, such as a home office, one can engage in “exercise snacks.” To do this, one interrupts sedentary activities throughout the day with short bursts of movement, said Dr. Joisten.
Dr. Kress agreed with this introductory concept. “With lower intensity and longer duration, you can achieve even more than with short, intense exercise sessions,” he told this news organization. For starters, he recommended “walking without panting,” such as walking or jogging at a pace that allows for conversation.
Even the first walk improves the condition of coronary arteries, Dr. Kress explained. Fragmented exercise sessions, such as three times for 10 min/d, benefit circulation and fitness, the expert emphasized. Moderate aerobic training also ensures effective fat burning and prevents lactic acid buildup.
The Next Step
Gradual progression can lead to longer or brisker walks. The goal does not always have to be 10,000 steps per day, as shown in a meta-analysis presented by Dr. Joisten. In individuals aged < 60 years, 8000-10,000 steps significantly reduced mortality. For those aged > 60 years, 6000-8000 steps were sufficient.
More exercise is even better. The WHO recommends 150-300 min/wk of exercise for adults, including seniors, equivalent to 30-60 min/d for 5 days a week. Additionally, strength training is recommended on 2 days a week — or for seniors, 3 days of combined training sessions with strength and balance components.
In a network meta-analysis, the following exercise regimens were compared for overweight or obese individuals:
- Interval training (very high intensity, 2-3 d/wk, averaging 91 min/wk)
- Strength training (2-3 d/wk, averaging 126 min/wk)
- Continuous endurance training (moderate intensity, 3-5 d/wk, averaging 176 min/wk)
- Combined training (3-4 d/wk, averaging 187 min/wk)
- Hybrid training (high intensity, such as dancing, jumping rope, ball sports, etc., 2-3 d/wk, averaging 128 min/wk).
Participants in the combined training group (which included the longest weekly training times) performed the best in all five endpoints: Body composition, blood lipid levels, blood sugar control, blood pressure, and cardiorespiratory fitness. However, hybrid training also produced good results.
First, Visit the Doctor
Patients who wish to exercise and have not done so in a while or who have cardiac-respiratory or orthopedic conditions should first undergo a medical checkup, Dr. Kress told this news organization.
In most cases, a test on a stationary bicycle at the primary care physician’s office would be sufficient. If higher athletic goals are sought, a sports physician or a cardiologist should be consulted.
However, when looking at weight loss alone, exercise may not go very far, said Dr. Joisten. Approximately 1.5-3.5 kg of body weight can be lost, as shown in a meta-analysis. Of this amount, about 1.3-2.6 kg is fat mass. Only 330-560 g of this total is visceral fat, which matters the most.
A Direct Comparison
Matthias Blüher, MD, an endocrinologist and diabetologist at the University Hospital Leipzig in Leipzig, Germany, represented the pro-injection position. He initially focused on body weight and presented a highly publicized study by Lundgren et al., which showed that treatment with 3.0 mg/d liraglutide was significantly more effective in terms of weight loss than moderate to intensive physical activity. After 12 months, patients who received the injection lost 6.8 kg, while those who exercised lost only 4.1 kg. “The injection wins in a direct comparison,” said Dr. Blüher.
The diabetologist also pointed out the risk for injury associated with exercise. Patients may become less active after a sports injury, he noted.
The LOOK-AHEAD study investigated whether a lifestyle program involving exercise and dietary changes brought cardiovascular benefits. In the long run, it did not. Patients regained weight after some time, and the combined cardiovascular endpoint did not differ between the group with an active, healthy lifestyle and the inactive control group. The study was discontinued.
The SELECT study compared the effect of treatment with once-weekly semaglutide 2.4 mg and placebo on cardiovascular events in patients with cardiovascular conditions and overweight or obesity (n = 17,604). Patients in the semaglutide arm had significantly fewer cardiovascular events over nearly 3 years than the comparison patients receiving placebo (6.5% vs 8.0%). Although the study participants did not have diabetes, they had relatively high baseline A1c levels; two thirds of the patients (n = 11,696) had prediabetes, with an A1c level ≥ 5.7%. Semaglutide significantly delayed the onset of diabetes in these patients, said Dr. Blüher.
A review in which Dr. Blüher was involved showed that treatment with 2.4 mg semaglutide or 15 mg tirzepatide over 12 months was more effective than many older medications (including orlistat) but not as effective as bariatric surgery. Participants in the Exercise and Nutrition study performed even worse than with the older medications.
Combination Therapy
Dr. Blüher and Dr. Joisten agreed that the combined prescription and use of exercise and incretin-based medications yields the best results for relevant endpoints such as weight loss and blood sugar control.
For example, data from the Lundgren study mentioned previously showed that participants in the combination group with liraglutide plus exercise lost an average of 9.5 kg of body weight. In addition, the A1c level, insulin sensitivity, and cardiorespiratory fitness of the participants in the combination group improved significantly over the course of the study.
The suggestion of an interval therapy (alternating between exercise and injections) enjoyed widespread approval during the audience discussion. Dr. Kress also supported the idea of interval therapy with incretin-based injections because it minimizes costs and could enhance insurance companies’ acceptance of this therapy.
But exercise should not be interrupted, he said, and perhaps patients would not want to take breaks either, hoping that “once someone has lost weight (for example, even under injection therapy) they gain new motivation to move and achieve more.”

Metformin Initiation Cuts Gout Risk in Prediabetes
TOPLINE:
Metformin use lowers the risk for gout by 32% in individuals with prediabetes; however, the treatment doesn’t change serum urate or C-reactive protein levels.
METHODOLOGY:
- Individuals with prediabetes not only are at an elevated risk for diabetes but also face an increased risk for incident gout. Many previous reports have demonstrated the efficacy of antidiabetic medications in reducing the risk for gout in adults with diabetes.
- This study assessed the gout-lowering properties of metformin in 25,064 individuals with prediabetes (age ≥ 18 years; A1c levels, 5.7%-6.4%) who had never reported A1c levels > 6.4%.
- Patients who were initiated on metformin within 18 months after the diagnosis of prediabetes (n = 1154) were propensity score–matched with those who did not initiate metformin or other antidiabetic medications in this period (n = 13,877) and were followed for a median of 3.9 years for the primary outcome of incident gout.
TAKEAWAY:
- Initiation vs no initiation of metformin resulted in 2.4 fewer cases of gout per 1000 person-years and a 32% reduced relative risk for incident gout (hazard ratio, 0.68; 95% CI, 0.48-0.96).
- The results were consistent across different subgroups stratified on the basis of sex, age (≤ 60 vs > 60 years), estimated glomerular filtration rate (≥ 90 vs < 90 mL/min/1.73 m2), and baseline diuretic use.
- Metformin initiation was not associated with significant changes in serum urate or C-reactive protein levels.
- Metformin use was associated with a reduction in A1c levels and body mass index.
IN PRACTICE:
The authors suggested that “metformin may be important in lowering gout risk in individuals with prediabetes.”

Javier Marrugo, MD, Department of Medicine, Brigham and Women’s Hospital, Boston, led this study, which was published online in Annals of the Rheumatic Diseases.
LIMITATIONS:
Although gout is more commonly observed in men, around 60% of the study population consisted of women. Owing to the observational nature of this study, exposure misclassifications might have occurred. Misclassification of the outcome is also possible due to the presence of two or more diagnostic codes for gout and/or the combination of urate-lowering therapies or colchicine with at least one diagnostic code.

TOPLINE:
Metformin use lowers the risk for gout by 32% in individuals with prediabetes; however, the treatment doesn’t change serum urate or C-reactive protein levels.
METHODOLOGY:
- Individuals with prediabetes not only are at an elevated risk for diabetes but also face an increased risk for incident gout. Many previous reports have demonstrated the efficacy of antidiabetic medications in reducing the risk for gout in adults with diabetes.

Semaglutide Kidney Benefits Extend to Those Without Diabetes
STOCKHOLM — Improvements in kidney function outcomes observed with glucagon-like peptide-1 (GLP-1) receptor agonists in patients with type 2 diabetes extend to patients who are overweight or obese but don›t yet have type 2 diabetes, new research shows.
“These data are important because they are the first data to suggest a kidney benefit of semaglutide in this patient population in the absence of diabetes,” lead author Helen M. Colhoun, MD, of the Institute of Genetics and Cancer, University of Edinburgh, Scotland, United Kingdom, told this news organization.
“This is a population at high risk of chronic kidney disease with an increased need for kidney protection,” she said.
The late-breaking study was presented this week at the 61st European Renal Association (ERA) Congress 2024 and simultaneously published in Nature Medicine.
SELECT Trial Patients Without Diabetes
The findings are from a secondary analysis of the randomized SELECT (Semaglutide Effects on Heart Disease and Stroke in Patients With Overweight or Obesity) trial, which evaluated cardiovascular outcomes of semaglutide treatment among 17,604 adults with preexisting cardiovascular disease who were overweight or obese — but did not have diabetes.
For its primary endpoint, the trial showed semaglutide was associated with a 20% reduction in major adverse cardiovascular events compared with placebo.
With obesity also associated with a significantly increased risk of chronic kidney disease — and the headline-making FLOW trial, also presented at the congress, showing key benefits of semaglutide in improving kidney function in people with CKD and type 2 diabetes the secondary analysis of SELECT was conducted to investigate whether those kidney benefits extended to people without type 2 diabetes.
Patients were randomized 1:1 to once-weekly subcutaneous semaglutide at a dose of 2.4 mg or placebo. Baseline patient characteristics were well-balanced, including kidney function and albuminuria status.
The primary endpoint for the analysis was a nephropathy composite of time from randomization to the first occurrence of death from kidney causes; initiation of chronic kidney replacement therapy; onset of persistent estimated glomerular filtration rate (eGFR) < 15 mL/min/1.73 m2; persistent ≥ 50% reduction in eGFR compared with baseline; or onset of persistent macroalbuminuria.
With a median follow-up of 182 weeks, the results showed that the semaglutide group was significantly less likely to develop the primary composite endpoint compared with the placebo group (1.8% vs 2.2%; hazard ratio [HR], 0.78; P = .02).
A significantly reduced decline in eGFR in the semaglutide group was observed at a prespecified 104-week time point, with a treatment effect of 0.75 mL/min/1.73 m2 (P < .001), and the effect was more pronounced among participants with baseline eGFR < 60 mL/min/1.73 m2 (P < .001).
Furthermore, those in the semaglutide group had a significantly lower proportionate increase in urinary albumin-to-creatinine ratio (UACR) compared with placebo (–10.7%; P < .001) at the prespecified 104 weeks, with a net treatment benefit of –27.2% and –31.4% among those with randomization to UACR 30 to < 300 mg/g and 2300 mg/g, respectively.
Improvements varied according to baseline UACR status and were more pronounced among those with macroalbuminuria, at –8.1% for those with normoalbuminuria (n = 14,848), –27% for microalbuminuria (n = 1968), and –31% for macroalbuminuria (n = 325).
There were no reports of acute kidney injury associated with semaglutide, regardless of baseline eGFR.
“We were hopeful that there would be similar benefits as those observed in the diabetes studies, but there are differences in kidney disease among those with and without type 2 diabetes, so we weren’t sure,” Dr. Colhoun told this news organization.
Benefits the Result of Weight Loss or Something Else?
Considering the beneficial effects of semaglutide on weight loss, underscored in an analysis also published this month that showed a mean 10.2% reduction in weight sustained for up to 4 years, a key question is whether the kidney benefits are a direct result of weight loss — or the drug mechanism or something else.
But Dr. Colhoun said the role of weight loss in terms of the kidney benefits is still uncertain, particularly considering the various other factors, including cardiometabolic improvements, which could also have an effect.
“It’s a very difficult question to answer,” she said. “We did do a mediation exploratory analysis suggesting a substantial part of the effect might be due to the weight change, but it’s difficult to demonstrate that because you have weight change going on in the placebo arm as well, but for different reasons,” she said.
“So, I would say the data suggest there is some component of this that is attributable to weight, but we certainly can’t attribute all of the [effects] to weight change.”
Small studies involving animals have shown a direct effect of semaglutide on kidney hemodynamics “but they’re small and not definitive,” Dr. Colhoun added.
And although weight loss achieved through other measures such as lifestyle changes show a small benefit on eGFR, “interestingly, those studies showed no effect at all on albuminuria, whereas we see a really substantial effect on albuminuria with semaglutide,” Dr. Colhoun said.
Studies of weight loss through bariatric surgery have shown kidney benefits; however, those were in the context of type 2 diabetes, unlike the current analysis.
In terms of whether the benefits may extend to tirzepatide, the dual glucose-dependent insulinotropic polypeptide (GIP)/GLP-1 receptor agonist, increasingly used in weight loss, results from another secondary analysis also show encouraging kidney benefits in people with type 2 diabetes, and there is ongoing research in patients with type 2 diabetes and those with obesity without diabetes, Dr. Colhoun noted.
Primary Prevention of CKD?
Limitations of the current analysis include that only about a fifth of participants in SELECT had an eGFR < 60 mL/min/1.73 m2 or UACR ≥ 30 mg/g at baseline, suggesting a relatively low proportion of participants with kidney disease.
Importantly, however, the kidney benefits observed in patients who are at such high risk of kidney disease but do not yet have diabetes or CKD, is encouraging, said Alberto Ortiz, MD, PhD, commenting on the study. Dr. Ortiz is chief of nephrology and the Hypertension Renal Unit, Health Research Institute of the Jiménez Díaz Foundation, Madrid, Spain.
“It is especially significant that protection was observed in participants with an eGFR > 60 mL/min/1.73 m2 and across UACR categories, ie, including people without CKD at baseline, in whom it appeared to decrease the incidence of de novo CKD,” Dr. Ortiz told this news organization.
“This suggests a potential role in primary prevention of CKD in this population,” he said.
To further investigate this, he said, “It would have been extremely interesting to assess whether there is a potential role for primary prevention of CKD in people without baseline CKD by assessing subgroup results for the no-CKD, low-risk KDIGO [Kidney Disease: Improving Global Outcomes] category [of patients].”
SELECT was funded by Novo Nordisk. Dr. Colhoun has reported consulting, research, and/or other relationships with Novo Nordisk, Bayer, Sanofi, Roche, and IQVIA. Dr. Ortiz has reported being a member of the European Renal Association council and Madrid Society of Nephrology (SOMANE), which developed a document in 2022 on the treatment of diabetic kidney disease sponsored by Novo Nordisk. He also reported collaborating with companies developing drugs for kidney disease.

FROM ERA 2024
The ASCO Annual Meeting Starts This Week
From its origins in 1964, ASCO’s annual event has grown to become the world’s largest clinical oncology meeting, drawing attendees from across the globe.
More than 7000 abstracts were submitted for this year’s meeting a new record — and over 5000 were selected for presentation.
This year’s chair of the Annual Meeting Education Committee, Thomas William LeBlanc, MD, told us he has been attending the meeting since his training days more than a decade ago.
The event is “just incredibly empowering and energizing,” Dr. LeBlanc said, with opportunities to catch up with old colleagues and meet new ones, learn how far oncology has come and where it’s headed, and hear clinical pearls to take back the clinic.
This year’s theme, selected by ASCO President Lynn M. Schuchter, MD, is “The Art and Science of Cancer Care: From Comfort to Cure.”
Dr. LeBlanc, a blood cancer specialist at Duke University, Durham, North Carolina, said the theme has been woven throughout the abstract and educational sessions. Most sessions will have at least one presentation related to how we support people — not only “when we cure them but also when we can’t cure them,” he said.
Topics will include patient well-being, comfort measures, and survivorship. And for the first time the plenary session will include a palliative care abstract that addresses whether or not palliative care can be delivered effectively through telemedicine. The session is on Sunday, June 2.
Other potentially practice changing plenary abstracts tackle immunotherapy combinations for resectable melanoma, perioperative chemotherapy vs neoadjuvant chemoradiation for esophageal cancer, and osimertinib after definitive chemoradiotherapy for unresectable non–small cell lung cancer.
ASCO is piloting a slightly different format for research presentations this year. Instead of starting with context and background, speakers have been asked to present study results upfront as well as repeat them at the end of the talk. The reason behind the tweak is that engagement and retention tend to be better when results are presented upfront, instead of just at the end of a talk.
A popular session — ASCO Voices — has also been given a more central position in the conference: Friday, May 31. In this session, speakers will give short presentations about their personal experiences as providers, researchers, or patients.
ASCO Voices is a relatively recent addition to the meeting that has grown and gotten better. The talks are usually “very powerful narratives” that remind clinicians about “the importance of what they’re doing each day,” Dr. LeBlanc said.
Snippets of the talks will be played while people wait for sessions to begin at the meeting, so attendees who miss the Friday talks can still hear them.
In terms of educational sessions, Dr. LeBlanc highlighted two that might be of general interest to practicing oncologists: A joint ASCO/American Association for Cancer Research session entitled “Drugging the ‘Undruggable’ Target: Successes, Challenges, and the Road Ahead,” on Sunday morning and “Common Sense Oncology: Equity, Value, and Outcomes That Matter” on Monday morning.
As a blood cancer specialist, he said he is particularly interested in the topline results from the ASC4FIRST trial of asciminib, a newer kinase inhibitor, in newly diagnosed chronic myeloid leukemia, presented on Friday.
As in past years, this news organization will be on hand providing coverage with a dedicated team of reporters, editors, and videographers. Stop by our exhibit hall booth — number 26030 — to learn about the tools we offer to support your practice.

Dr. LeBlanc, a blood cancer specialist at Duke University, Durham, North Carolina, said the theme has been woven throughout the abstract and educational sessions. Most sessions will have at least one presentation related to how we support people — not only “when we cure them but also when we can’t cure them,” he said.
Topics will include patient well-being, comfort measures, and survivorship. And for the first time the plenary session will include a palliative care abstract that addresses whether or not palliative care can be delivered effectively through telemedicine. The session is on Sunday, June 2.
Other potentially practice changing plenary abstracts tackle immunotherapy combinations for resectable melanoma, perioperative chemotherapy vs neoadjuvant chemoradiation for esophageal cancer, and osimertinib after definitive chemoradiotherapy for unresectable non–small cell lung cancer.
ASCO is piloting a slightly different format for research presentations this year. Instead of starting with context and background, speakers have been asked to present study results upfront as well as repeat them at the end of the talk. The reason behind the tweak is that engagement and retention tend to be better when results are presented upfront, instead of just at the end of a talk.
A popular session — ASCO Voices — has also been given a more central position in the conference: Friday, May 31. In this session, speakers will give short presentations about their personal experiences as providers, researchers, or patients.
ASCO Voices is a relatively recent addition to the meeting that has grown and gotten better. The talks are usually “very powerful narratives” that remind clinicians about “the importance of what they’re doing each day,” Dr. LeBlanc said.
Snippets of the talks will be played while people wait for sessions to begin at the meeting, so attendees who miss the Friday talks can still hear them.
In terms of educational sessions, Dr. LeBlanc highlighted two that might be of general interest to practicing oncologists: A joint ASCO/American Association for Cancer Research session entitled “Drugging the ‘Undruggable’ Target: Successes, Challenges, and the Road Ahead,” on Sunday morning and “Common Sense Oncology: Equity, Value, and Outcomes That Matter” on Monday morning.
As a blood cancer specialist, he said he is particularly interested in the topline results from the ASC4FIRST trial of asciminib, a newer kinase inhibitor, in newly diagnosed chronic myeloid leukemia, presented on Friday.

From its origins in 1964, ASCO’s annual event has grown to become the world’s largest clinical oncology meeting, drawing attendees from across the globe.
More than 7000 abstracts were submitted for this year’s meeting a new record — and over 5000 were selected for presentation.
This year’s chair of the Annual Meeting Education Committee, Thomas William LeBlanc, MD, told us he has been attending the meeting since his training days more than a decade ago.
The event is “just incredibly empowering and energizing,” Dr. LeBlanc said, with opportunities to catch up with old colleagues and meet new ones, learn how far oncology has come and where it’s headed, and hear clinical pearls to take back the clinic.
