Sulfonylureas as street drugs: Hidden hypoglycemia cause
SEATTLE – .
“Physicians should be aware of this possibility and consider intentional or unintentional sulfonylurea abuse, with or without other drugs,” Amanda McKenna, MD, a first-year endocrinology fellow at the Mayo Clinic, Jacksonville, Fla., and colleagues say in a poster presented at the annual scientific & clinical congress of the American Association of Clinical Endocrinology.
The new case, seen in Florida, involves a 33-year-old man with a history of narcotic dependence and anxiety but not diabetes. At the time of presentation, the patient was unconscious and diaphoretic. The patient’s blood glucose level was 18 mg/dL. He had purchased two unmarked, light blue pills on the street which he thought were Valiums but turned out to be glyburide.
Sulfonylureas have no potential for abuse, but they physically resemble Valiums and are easier for illicit drug dealers to obtain because they’re not a controlled substance, and they can be sold for considerably more money, Dr. McKenna said in an interview.
“He thought he was getting Valium, but what he really purchased was glyburide. ... When he took it, he developed sweating and weakness. He probably thought he was having a bad trip, but it was really low blood sugar,” she said.
Similar cases go back nearly two decades
Similar cases have been reported as far back as 2004 in different parts of the United States. A 2004 article reports five cases in which people in San Francisco were “admitted to the hospital for hypoglycemia as a result of a drug purchased on the streets as a presumed benzodiazepine.”
Two more cases of “glyburide poisoning by ingestion of ‘street Valium,’ ” also from San Francisco, were reported in 2012. And in another case presented at the 2022 Endocrine Society meeting, sulfonylurea had been cut with cocaine, presumably to increase the volume.
The lead author of the 2012 article, Craig Smollin, MD, medical director of the California Poison Control System, San Francisco Division, and professor of emergency medicine at the University of California, San Francisco, told this news organization that his team has seen “a handful of cases over the years” but that “it is hard to say how common it is because hypoglycemia is common in this patient population for a variety of reasons.”
Persistent hypoglycemia led to the source
In the current case, paramedics treated the patient with D50W, and his blood glucose level increased from 18 mg/dL to 109 mg/dL. He regained consciousness but then developed recurrent hypoglycemia, and his blood glucose level dropped back to 15 mg/dL in the ED. Urine toxicology results were positive for benzodiazepines, cannabis, and cocaine.
Laboratory results showed elevations in levels of insulin (47.4 mIU/mL), C-peptide (5.4 ng/mL), and glucose (44 mg/dL). He was again treated with D50W, and his blood glucose level returned to normal over 20 hours. Once alert and oriented, he reported no personal or family history of diabetes. A 72-hour fast showed no evidence of insulinoma. A sulfonylurea screen was positive for glyburide. He was discharged home in stable condition. How many more cases have been missed?
Dr. McKenna pointed out that a typical urine toxicology screen for drugs wouldn’t detect a sulfonylurea. “The screen for hypoglycemic agents is a blood test, not a urine screen, so it’s completely different in the workup, and you really have to be thinking about that. It typically takes a while to come back,” she said.
She added that if the hypoglycemia resolves and testing isn’t conducted, the cause of the low blood sugar level might be missed. “If the hypoglycemia doesn’t persist, the [ED] physician wouldn’t consult endocrine. ... Is this happening more than we think?”
Ocreotide: A ‘unique antidote’
In their article, Dr. Smollin and colleagues describe the use of ocreotide, a long-acting somatostatin agonist that reverses the insulin-releasing effect of sulfonylureas on pancreatic beta cells, resulting in diminished insulin secretion. Unlike glucose supplementation, ocreotide doesn’t stimulate additional insulin release. It is of longer duration than glucagon, the authors say.
“The management of sulfonylurea overdose includes administration of glucose but also may include the use of octreotide, a unique antidote for sulfonylurea induced hypoglycemia,” Dr. Smollin said.
However, he also cautioned, “there is a broad differential diagnosis for hypoglycemia, and clinicians must consider many alternative diagnoses.”
Dr. McKenna and Dr. Smollin have disclosed no relevant financial relationships.

AT AACE 2023
New AACE type 2 diabetes algorithm individualizes care
SEATTLE – The latest American Association of Clinical Endocrinology type 2 diabetes management algorithm uses graphics to focus on individualized care while adding newly compiled information about medication access and affordability, vaccinations, and weight loss drugs.
The clinical guidance document was presented at the annual scientific & clinical congress of the American Association of Clinical Endocrinology and simultaneously published in Endocrine Practice.
Using text and colorful graphics, the document summarizes information from last year’s update and other recent AACE documents, including those addressing dyslipidemia and use of diabetes technology.
lead author Susan L. Samson, MD, PhD, chair of endocrinology, diabetes & metabolism at the Mayo Clinic Florida, Jacksonville, said in an interview.
Asked to comment, Anne L. Peters, MD, professor of clinical medicine at the University of Southern California, Los Angeles, said: “I like their simple graphics. For the Department of Health Services in Los Angeles County, we have been painstakingly trying to create our own flow diagrams. ... These will help.”
Eleven separate algorithms with text and graphics
Included are 11 visual management algorithms, with accompanying text for each one. The first lists 10 overall management principles, including “lifestyle modification underlies all therapy,” “maintain or achieve optimal weight,” “choice of therapy includes ease of use and access,” “individualize all glucose targets,” “avoid hypoglycemia,” and “comorbidities must be managed for comprehensive care.”
Three more algorithms cover the diabetes-adjacent topics of adiposity-based chronic disease, prediabetes, dyslipidemia, and hypertension.
Four separate graphics address glucose-lowering. Two are “complications-centric” and “glucose-centric” algorithms, another covers insulin initiation and titration, and a table summarizes the benefits and risks of currently available glucose-lowering medications, as well as cost.
Splitting the glucose-lowering algorithms into “complications-centric” and “glucose-centric” graphics is new, Dr. Samson said. “The complications one comes first, deliberately. You need to think about: Does my patient have a history of or high risk for cardiovascular disease, heart failure, stroke, or diabetic kidney disease? And, you want to prioritize those medications that have evidence to improve outcomes with those different diabetes complications versus a one-size-fits-all approach.”
And for patients without those complications, the glucose-centric algorithm considers obesity, hypoglycemia risk, and access/cost issues. “So, overall the diabetes medication algorithm has been split in order to emphasize that personalized approach to decision-making,” Dr. Samson explained.
Also new is a table listing the benefits and risks of weight-loss medications, and another covering immunization guidance for people with diabetes based on recommendations from the U.S. Centers for Disease Control and Prevention. “Coming out of the pandemic, we’re thinking about how can we protect our patients from infectious disease and all the comorbidities. In some cases, people with diabetes can have a much higher risk for adverse events,” Dr. Samson noted.
Regarding the weight-loss medications table, she pointed out that the task force couldn’t include the blockbuster twincretin tirzepatide because it’s not yet approved for weight loss by the U.S. Food and Drug Administration. However, it is included in the glucose-lowering drug table with weight loss listed among its benefits.
“We want this to be a living document that should be updated in a timely fashion, and so, as these new indications are approved and we see more evidence supporting their different uses, this should be updated in a really timely fashion to reflect that,” Dr. Samson said.
The end of the document includes a full page of each graphic, meant for wall posting.
Dr. Peters noted that for the most part, the AACE guidelines and algorithm align with joint guidance by the American Diabetes Association and European Association for the Study of Diabetes.
“For many years there seemed to be big differences between the AACE and ADA guidelines for the management of type 2 diabetes. Although small differences still exist ... the ADA and AACE guidelines have become quite similar,” she said.
Dr. Peters also praised the AACE algorithm for providing “a pathway for people who have issues with access and cost.”
“I am incredibly proud that in the County of Los Angeles you can get a [glucagon-like peptide-1 receptor agonist] and/or a [sodium-glucose cotransporter-2 inhibitor] even with the most restricted MediCal insurance if indications are met. But there remain many people in many places where access and cost limit options, and I am grateful that AACE includes this in their algorithms,” she said.
Dr. Samson has reported receiving research support to the Mayo Clinic from Corcept, serving on a steering committee and being a national or overall principal investigator for Chiasma and Novartis, and being a committee chair for the American Board of Internal Medicine. Dr. Peters has reported relationships with Blue Circle Health, Vertex, and Abbott Diabetes Care, receiving research grants from Abbott Diabetes Care and Insulet, and holding stock options in Teladoc and Omada Health.

AT AACE 2023
New AACE statement tries to fight weight bias and stigma
SEATTLE –
Highlights from the statement, entitled “Addressing stigma and bias in the diagnosis and management of patients with obesity/adiposity-based chronic disease and assessing bias and stigmatization as determinants of disease severity,” were presented at the annual scientific & clinical congress of the American Association of Clinical Endocrinology. It will be published later this year in Endocrine Practice.
The document reiterates AACE’s previous proposal to use the term “adiposity-based chronic disease (ABCD)” to refer to the spectrum of complications of obesity beyond weight. AACE has incorporated weight bias, stigmatization, psychological health, and social determinants of health into disease staging based on the degree to which these factors impair quality of life and could negatively affect treatment. Another change is the use of a scale from 1 to 3 for ABCD staging, in contrast to the previous scale from 0 to 3, as follows.
Stage 1 (previously 0): No known physical ABCD complications (for example, cardiovascular, biomechanical) but with increased risk that might be reduced by weight loss, and/or internalized weight bias and stigmatization, psychological conditions, and social determinants of health that don’t have immediate adverse health effects but may require individualized care.
Stage 2 (previously 1): One or more mild-moderate ABCD complications plus increased risk of other complications and/or bias/stigma/social determinants that adversely affect quality of life or could impair ABCD treatment.
Stage 3 (previously 2): At least one severe ABCD complication plus increased risk for others, and/or bias/stigma/social determinants with pronounced adverse effects on quality of life or that interfere with weight loss treatment plans or render them harmful.
To accomplish this staging, clinicians are advised to use validated questionnaires to screen patients for the presence and degree of self-stigmatization and internalized weight bias and to refer patients to mental health professionals for related psychological issues. The document also advises clinicians to implement practice policies such as implicit bias training and obesity education for their staff.
“I really hope that this document will increase awareness of the vicious cycle of weight bias, stigma, and internalized weight bias for patients with obesity, both on an individual basis and a bigger chronic care model basis ... By utilizing these concepts in the document, we hope to at least take steps towards reducing the stigma and internalized weight bias and slowing down or reversing that vicious cycle to better care for people with a focus on their health ... It’s not just about a person’s weight,” Karl Nadolsky, DO, the statement’s co-lead author, said.
The new statement builds on previous AACE efforts, including the 2014 publication entitled, “Advanced framework for a new diagnosis of obesity as a chronic disease,” the 2016 management guidelines, and the 2016 position statement, which introduced the ABCD term. All are meant to advance the concept of obesity or ABCD as a medical condition, rather than a cosmetic problem or lifestyle choice.
Now, AACE is explicitly calling attention to the integral role of internal and external weight bias and stigma as both drivers and complications of the condition. The AACE writing panel adopted some of the concepts from a 2020 international consensus statement focusing on obesity stigma, Dr. Nadolsky said.
“We need to focus on health, the biopsychosocial mode. We have to think about the person as a whole. The disease of obesity is really a quintessential disease state that needs a very good holistic approach,” he said.
Asked to comment, Yoni Freedhoff, MD, associate professor, department of family medicine, University of Ottawa, and Medical Director of the Bariatric Medical Institute, said: “I do think staging/categorization are important in the context of bias and stigma and also to combat the notion that the goal is simple medicalization ... It’s good to see the consideration of internalized weight bias as part of an effort to understand the impact of obesity on an individual.”
However, Dr. Freedhoff said he would have preferred that the implicit and internalized bias concepts had been incorporated into the 2009 Edmonton Obesity Staging System, which he believes is easier to use than the AACE staging system.
Dr. Freedhoff also disagrees that it was necessary to remove “0” from the staging (still present in the Edmonton system), done by AACE out of concern that people might mistakenly think it implies zero risk. “It just means no current objective or subjective impact of weight on health or quality of life,” he said.
But, Dr. Nadolsky noted that data on people with “metabolically healthy obesity” suggest that “they might have zero complications but they’re still at high risk, from cancer to stigma and bias, which are a cause of and consequence of obesity and should be part of the ABCD staging system.”
Indeed, Dr. Freedhoff noted, “Obesity confers risk. Just like hypertension. And just like with hypertension, risk is not a guarantee of problems. But we still discuss treatment and people can be symptom- or problem-free when we start it. It can also be ‘borderline’ or mild. But no one gets upset about the idea of treating a known risk factor, or diagnosing a known risk factor, when minor, and when it’s not had any impact on a person’s health. That we don’t do same with obesity is consequent to bias.”
In addition to influencing health care providers and health care systems, the statement also concludes: “Society, including payers and policymakers, should support policies, education, research, and access to care to limit bias and stigma faced by individuals with obesity/ABCD.”
Dr. Nadolsky has reported no relevant financial relationships. Dr. Freedhoff has reported working with the Bariatric Medical Institute and Constant Health, which has received a research grant from Novo Nordisk.

Stage 1 (previously 0): No known physical ABCD complications (for example, cardiovascular, biomechanical) but with increased risk that might be reduced by weight loss, and/or internalized weight bias and stigmatization, psychological conditions, and social determinants of health that don’t have immediate adverse health effects but may require individualized care.
Stage 2 (previously 1): One or more mild-moderate ABCD complications plus increased risk of other complications and/or bias/stigma/social determinants that adversely affect quality of life or could impair ABCD treatment.
Stage 3 (previously 2): At least one severe ABCD complication plus increased risk for others, and/or bias/stigma/social determinants with pronounced adverse effects on quality of life or that interfere with weight loss treatment plans or render them harmful.
To accomplish this staging, clinicians are advised to use validated questionnaires to screen patients for the presence and degree of self-stigmatization and internalized weight bias and to refer patients to mental health professionals for related psychological issues. The document also advises clinicians to implement practice policies such as implicit bias training and obesity education for their staff.
“I really hope that this document will increase awareness of the vicious cycle of weight bias, stigma, and internalized weight bias for patients with obesity, both on an individual basis and a bigger chronic care model basis ... By utilizing these concepts in the document, we hope to at least take steps towards reducing the stigma and internalized weight bias and slowing down or reversing that vicious cycle to better care for people with a focus on their health ... It’s not just about a person’s weight,” Karl Nadolsky, DO, the statement’s co-lead author, said.
The new statement builds on previous AACE efforts, including the 2014 publication entitled, “Advanced framework for a new diagnosis of obesity as a chronic disease,” the 2016 management guidelines, and the 2016 position statement, which introduced the ABCD term. All are meant to advance the concept of obesity or ABCD as a medical condition, rather than a cosmetic problem or lifestyle choice.
Now, AACE is explicitly calling attention to the integral role of internal and external weight bias and stigma as both drivers and complications of the condition. The AACE writing panel adopted some of the concepts from a 2020 international consensus statement focusing on obesity stigma, Dr. Nadolsky said.
“We need to focus on health, the biopsychosocial mode. We have to think about the person as a whole. The disease of obesity is really a quintessential disease state that needs a very good holistic approach,” he said.
Asked to comment, Yoni Freedhoff, MD, associate professor, department of family medicine, University of Ottawa, and Medical Director of the Bariatric Medical Institute, said: “I do think staging/categorization are important in the context of bias and stigma and also to combat the notion that the goal is simple medicalization ... It’s good to see the consideration of internalized weight bias as part of an effort to understand the impact of obesity on an individual.”
However, Dr. Freedhoff said he would have preferred that the implicit and internalized bias concepts had been incorporated into the 2009 Edmonton Obesity Staging System, which he believes is easier to use than the AACE staging system.
Dr. Freedhoff also disagrees that it was necessary to remove “0” from the staging (still present in the Edmonton system), done by AACE out of concern that people might mistakenly think it implies zero risk. “It just means no current objective or subjective impact of weight on health or quality of life,” he said.
But, Dr. Nadolsky noted that data on people with “metabolically healthy obesity” suggest that “they might have zero complications but they’re still at high risk, from cancer to stigma and bias, which are a cause of and consequence of obesity and should be part of the ABCD staging system.”
Indeed, Dr. Freedhoff noted, “Obesity confers risk. Just like hypertension. And just like with hypertension, risk is not a guarantee of problems. But we still discuss treatment and people can be symptom- or problem-free when we start it. It can also be ‘borderline’ or mild. But no one gets upset about the idea of treating a known risk factor, or diagnosing a known risk factor, when minor, and when it’s not had any impact on a person’s health. That we don’t do same with obesity is consequent to bias.”
In addition to influencing health care providers and health care systems, the statement also concludes: “Society, including payers and policymakers, should support policies, education, research, and access to care to limit bias and stigma faced by individuals with obesity/ABCD.”
Dr. Nadolsky has reported no relevant financial relationships. Dr. Freedhoff has reported working with the Bariatric Medical Institute and Constant Health, which has received a research grant from Novo Nordisk.

SEATTLE –
Highlights from the statement, entitled “Addressing stigma and bias in the diagnosis and management of patients with obesity/adiposity-based chronic disease and assessing bias and stigmatization as determinants of disease severity,” were presented at the annual scientific & clinical congress of the American Association of Clinical Endocrinology. It will be published later this year in Endocrine Practice.
The document reiterates AACE’s previous proposal to use the term “adiposity-based chronic disease (ABCD)” to refer to the spectrum of complications of obesity beyond weight. AACE has incorporated weight bias, stigmatization, psychological health, and social determinants of health into disease staging based on the degree to which these factors impair quality of life and could negatively affect treatment. Another change is the use of a scale from 1 to 3 for ABCD staging, in contrast to the previous scale from 0 to 3, as follows.

Stage 2 (previously 1): One or more mild-moderate ABCD complications plus increased risk of other complications and/or bias/stigma/social determinants that adversely affect quality of life or could impair ABCD treatment.
Stage 3 (previously 2): At least one severe ABCD complication plus increased risk for others, and/or bias/stigma/social determinants with pronounced adverse effects on quality of life or that interfere with weight loss treatment plans or render them harmful.
To accomplish this staging, clinicians are advised to use validated questionnaires to screen patients for the presence and degree of self-stigmatization and internalized weight bias and to refer patients to mental health professionals for related psychological issues.

Radiofrequency ablation successful in small thyroid cancers
SEATTLE –
RFA is increasingly gaining favor as a less-invasive alternative to surgery for patients with large, symptomatic, benign thyroid nodules in the United States and elsewhere and for the treatment of thyroid microcarcinomas in other countries, particularly South Korea and China.
Now, new findings from eight patients seen at the Mayo Clinic are the first to be reported for use of RFA for PTMC in the United States, Kharisa Rachmasari, MD, an endocrinology fellow at Mayo, said at the annual scientific & clinical congress of the American Association of Clinical Endocrinology.
Papillary thyroid cancers of 10 mm or less are the most common thyroid cancers, and their incidence is rising. They are commonly discovered incidentally in the setting of increased cross-sectional imaging. These tiny cancers are typically indolent, and they are associated with an excellent prognosis. In the United States, standard management is either surveillance or surgery, whereas RFA has been used in Europe and Asia for more than a decade, Dr. Rachmasari said.
“There has been some hesitancy when it comes to cancer, because there’s no guarantee that we can do it in such a clean way as is done with surgery, where you can actually confirm a negative margin in pathology. And the follow-up is easier as well. With RFA, the PTMC is still there, and you can only follow it with ultrasound, not biochemically with thyroglobulin or certain biomarkers,” she said in an interview.
Nonetheless, for these eight patients who underwent the procedure at Mayo’s ablation clinic, where interventional radiologists team up with endocrinologists, there were no serious adverse events, and no further interventions were required during 24 months of follow-up, she reported.
Asked to comment, session moderator Anupam Kotwal, MD, assistant professor in the division of diabetes, endocrinology and metabolism at the University of Nebraska, Omaha, said, “It’s very novel. We talk about balancing the comorbidities that come from treatment of thyroid cancer, but at the same time we want to treat it appropriately ... And of course, there are patient factors. Some may prefer to have the cancer completely out, while others are okay with watching and are against any cuts in their neck. This comes as kind of a middle ground.”
But, Dr. Kotwal added, “[Investigators] definitely need to do a bit more work, especially in the population that may be at higher risk of cancer spread, such as those with a family history of thyroid cancer. We still don’t know how autoimmune disease influences cancer progression.”
He said that if RFA is to be used for PTMC, “I think it has to be done at a center that specializes in multidisciplinary care of thyroid cancers where there are not only the experts in doing the RFA procedure but also surgical expertise, in case a complication does happen, like a vocal cord injury. Or if the cancer is growing, they can expedite getting the person that appropriate treatment.”
An alternative to waiting vs. surgery?
The eight patients were seen at Mayo Clinic between July 2020 and February 2023. All had papillary thyroid carcinoma that was confirmed cytologically via fine-needle biopsy and single lesions without lymph node metastasis. All patients had been offered RFA as an alternative to either surgery or active surveillance.
Seven patients were female, and one was male (mean age, 53 years). All were euthyroid at baseline, and two were receiving thyroid hormone therapy. The mean diameter of their nodules was 9.5 mm, and the mean volume was 0.3 mL.
For the first six patients, the procedure was conducted under general anesthesia; deep sedation was used for the next patient, and moderate sedation was used for the most recent. “As we learn more and gain more experience, patients nowadays have moderate sedation,” she explained.
The active tip size was 10 mm for five patients and 7 mm with three. The radiofrequency power that was delivered ranged from 25 to 45 watts. The median ablation duration was 6 minutes and ranged from 2 to 14.5. “Patients usually stay in the suite about half an hour, so it’s a quick procedure, and the patient can go home on the same day,” Dr. Rachmasari said.
Following the procedure, the ablated area increased in size during the first 3-6 months because the ablation was applied beyond the cancer margins in an attempt to ensure a negative margin, as is done surgically. By 18 months, the ablated area had shrunk and resolved.
All patients remained euthyroid in 18-24 months’ follow-up, none had any cervical adenopathy, and none required subsequent intervention.
No significant adverse events were observed during or after the RFA procedure. A few patients complained of erythema and soreness around the area of the procedure, but this resolved with over-the-counter analgesia.
Longer follow-up will be necessary to detect any recurrence, Dr. Rachmasari noted.
Dr. Kotwal pointed out that lack of reimbursement for RFA has contributed to the slow adoption of RFA overall for the treatment of thyroid nodules in the United States, but added, “I think that will change quickly, especially with more and more data coming out about large benign nodules ... I think at least from the benign nodule standpoint, with discussions happening at national meetings and societies, it should push the payers to cover.”
Overall, he said, “If you have a complication or it affects quality of life, all of those things add to the cost. So if you can use a procedure early on to prevent increasing size of either the big nodule or reduce the size of a big nodule, or even a small cancer, and give that person months or years, even if they ultimately need surgery, I think that’s still a benefit for their quality of life. But again, we have to take patient factors into account.”
Dr. Rachmasari and Dr. Kotwal have disclosed no relevant financial relationships.

Contact allergens lurk in diabetes devices
in a presentation at the annual meeting of the American Contact Dermatitis Society.
Advanced technologies used for the management of diabetes fall into three main categories, said Dr. Chen, of the department of dermatology, Stanford University, Redwood City, Calif. Continuous glucose monitoring (CGM) devices, which are worn on the body, collect glucose measurements. Continuous subcutaneous insulin infusion (CSII) devices are attached to the body via an infusion set and are now available as tubing-free patch pumps that are attached directly to the skin via a catheter. Glucose-responsive insulin delivery systems combine the sensing and delivery features of the other two types of devices.
Once thought to be rare, reports of skin complications related to diabetes devices have been increasing in recent years, she said. Some reports suggest that at any given time, skin complications may affect as many as one quarter to one half of patients who use these devices, “so this is an important issue,” she emphasized. “Skin reactions are a major factor in device discontinuation, so we as clinicians need to be really proactive about treating these reactions.”
Risk factors for skin complications related to diabetes devices include sensitization to the adhesive used with the devices, as well as prolonged exposure to the device, Dr. Chen said. Younger age also appears to be a risk factor, as is a compromised skin barrier in the area where the device is used.
Unfortunately, obtaining details on the specific adhesives and the raw materials used in these devices, so as to customize patch testing, remains a challenge, she said. “Patch testing initially was often negative to commercially available allergens, even while patients were testing positive to pieces of device adhesive,” she noted.
Consider isobornyl acrylate
An article published in 2017 in Contact Dermatitis was “a major breakthrough” in that it identified isobornyl acrylate (IBOA) as an allergen in connection with the Freestyle Libre, a CGM device that was relatively new at the time. The finding was serendipitous, Dr. Chen said. A patient being treated for suspected allergic contact dermatitis in connection with use of a Freestyle Libre device was tested for IBOA accidentally, after the nurse administering the patch test thought that this was part of the standard acrylate series, she explained.
Subsequently, researchers identified 15 patients who had experienced reactions to the Freestyle Libre; 12 of 13 patients who were patch tested for IBOA tested positive. IBOA was found throughout the device, particularly where the top and bottom plastic components were connected, Dr. Chen said. This suggested that the IBOA was in the device housing and had diffused into the adhesive that attached the device to the skin.
An article published in 2018 in the Journal of Diabetes Science described three patients who developed severe allergic contact dermatitis from IBOA while using a CGM device, Dr. Chen said. The investigators confirmed that there were no reactions to the adhesive itself, again suggesting that IBOA had diffused into the adhesive from other parts of the device.
Although the authors were bound by a confidentiality agreement regarding the individual adhesive components, “the authors noted most of the acrylates in the adhesive were not present in commercially available acrylate series for patch testing,” she said.
IBOA, the ACDS’ Allergen of the Year in 2020, is common in sealants, glues, and adhesives, Dr. Chen said. Although IBOA had been reported infrequently as an allergen, it has now been identified as a “potential culprit” behind skin reactions in many diabetes devices, including CSII and CGM devices, she added.
In addition, N,N-dimethylacrylamide (DMAA) is an allergen that has been identified in several diabetes devices and often occurs with IBOA in medical-grade UV-cured adhesives, Dr. Chen noted. Other allergens identified in diabetes devices include colophony, which is present in many adhesives, as well as other acrylates and epoxy resin.
Diabetes devices are constantly evolving. IBOA is no longer found in Freestyle Libre devices. It is important that clinicians stay up to date with the medical literature and advocate for partnership with device manufacturers, she emphasized.
Patch testing
When diabetes devices are suspected as the source of allergic contact dermatitis, a minimum of a baseline series that contains colophony at a concentration of 20% in petrolatum should be carried out, Dr. Chen said. Commercialized patch test trays, which include plastics, glues, acrylates, epoxy resins/isocyanates, and colophony derivatives, should be ideal. “Personal-care products should be included if they are potentially relevant,” she added.
Dr. Chen shared tables published in Contact Dermatitis in 2021 with examples of screening test series. She said to consider including screening for other allergens more recently discovered in diabetes devices, including 2,2’-methylenebis(6-tert-butyl-4-methylphenol) monoacrylate (MBPA) 1.5% pet; dipropylene glycol diacrylate (DPGDA) 0.1% pet; and butylated hydroxytoluene (BHT) 2% pet.
Testing for monomethyl ether of hydroquinone should also be considered; this may be included in the test preparations for IBOA and DMAA.
Management strategies
For patients who experience skin reactions to their diabetes devices, consideration may given to relocating the device to another area of skin or changing sensors more frequently, according to Dr. Chen.
For some patients, the reaction can be managed with corticosteroid cream, ointment, solution, or nasal spray. Topical antibiotics or topical antihistamines can be helpful, as can barrier dressings, solutions, or sprays, she said. The best solution is to change to a device that does not have the culprit allergen, “but that is difficult, since we don’t know what is in these devices,” she added. Good alternatives include the Eversense CGM device or devices that have been demonstrated not to contain IBOA, such as the Freestyle Libre 2 or the newer version of the Omnipod, an insulin delivery system
Looking ahead, Dr. Chen said that “mandatory labeling is needed, as devices with the same name may have different compositions, depending on the date of manufacture.” Allergens relevant to people with diabetes are constantly evolving, and many are still unidentified, so clinicians and manufacturers need to work together to identify the culprit allergens and their sources, she said.
Dr. Chen has served as principal investigator or subinvestigator for Amgen, AbbVie, and Sanofi Regeneron and as a consultant for Purity Brands.

Unfortunately, obtaining details on the specific adhesives and the raw materials used in these devices, so as to customize patch testing, remains a challenge, she said. “Patch testing initially was often negative to commercially available allergens, even while patients were testing positive to pieces of device adhesive,” she noted.
Consider isobornyl acrylate
An article published in 2017 in Contact Dermatitis was “a major breakthrough” in that it identified isobornyl acrylate (IBOA) as an allergen in connection with the Freestyle Libre, a CGM device that was relatively new at the time. The finding was serendipitous, Dr. Chen said. A patient being treated for suspected allergic contact dermatitis in connection with use of a Freestyle Libre device was tested for IBOA accidentally, after the nurse administering the patch test thought that this was part of the standard acrylate series, she explained.
Subsequently, researchers identified 15 patients who had experienced reactions to the Freestyle Libre; 12 of 13 patients who were patch tested for IBOA tested positive. IBOA was found throughout the device, particularly where the top and bottom plastic components were connected, Dr. Chen said. This suggested that the IBOA was in the device housing and had diffused into the adhesive that attached the device to the skin.
An article published in 2018 in the Journal of Diabetes Science described three patients who developed severe allergic contact dermatitis from IBOA while using a CGM device, Dr. Chen said. The investigators confirmed that there were no reactions to the adhesive itself, again suggesting that IBOA had diffused into the adhesive from other parts of the device.
Although the authors were bound by a confidentiality agreement regarding the individual adhesive components, “the authors noted most of the acrylates in the adhesive were not present in commercially available acrylate series for patch testing,” she said.
IBOA, the ACDS’ Allergen of the Year in 2020, is common in sealants, glues, and adhesives, Dr. Chen said. Although IBOA had been reported infrequently as an allergen, it has now been identified as a “potential culprit” behind skin reactions in many diabetes devices, including CSII and CGM devices, she added.
In addition, N,N-dimethylacrylamide (DMAA) is an allergen that has been identified in several diabetes devices and often occurs with IBOA in medical-grade UV-cured adhesives, Dr. Chen noted. Other allergens identified in diabetes devices include colophony, which is present in many adhesives, as well as other acrylates and epoxy resin.
Diabetes devices are constantly evolving. IBOA is no longer found in Freestyle Libre devices. It is important that clinicians stay up to date with the medical literature and advocate for partnership with device manufacturers, she emphasized.
Patch testing
When diabetes devices are suspected as the source of allergic contact dermatitis, a minimum of a baseline series that contains colophony at a concentration of 20% in petrolatum should be carried out, Dr. Chen said. Commercialized patch test trays, which include plastics, glues, acrylates, epoxy resins/isocyanates, and colophony derivatives, should be ideal. “Personal-care products should be included if they are potentially relevant,” she added.
Dr. Chen shared tables published in Contact Dermatitis in 2021 with examples of screening test series. She said to consider including screening for other allergens more recently discovered in diabetes devices, including 2,2’-methylenebis(6-tert-butyl-4-methylphenol) monoacrylate (MBPA) 1.5% pet; dipropylene glycol diacrylate (DPGDA) 0.1% pet; and butylated hydroxytoluene (BHT) 2% pet.
Testing for monomethyl ether of hydroquinone should also be considered; this may be included in the test preparations for IBOA and DMAA.
Management strategies
For patients who experience skin reactions to their diabetes devices, consideration may given to relocating the device to another area of skin or changing sensors more frequently, according to Dr. Chen.
For some patients, the reaction can be managed with corticosteroid cream, ointment, solution, or nasal spray. Topical antibiotics or topical antihistamines can be helpful, as can barrier dressings, solutions, or sprays, she said. The best solution is to change to a device that does not have the culprit allergen, “but that is difficult, since we don’t know what is in these devices,” she added. Good alternatives include the Eversense CGM device or devices that have been demonstrated not to contain IBOA, such as the Freestyle Libre 2 or the newer version of the Omnipod, an insulin delivery system
Looking ahead, Dr. Chen said that “mandatory labeling is needed, as devices with the same name may have different compositions, depending on the date of manufacture.” Allergens relevant to people with diabetes are constantly evolving, and many are still unidentified, so clinicians and manufacturers need to work together to identify the culprit allergens and their sources, she said.
Dr. Chen has served as principal investigator or subinvestigator for Amgen, AbbVie, and Sanofi Regeneron and as a consultant for Purity Brands.

in a presentation at the annual meeting of the American Contact Dermatitis Society.
Advanced technologies used for the management of diabetes fall into three main categories, said Dr. Chen, of the department of dermatology, Stanford University, Redwood City, Calif. Continuous glucose monitoring (CGM) devices, which are worn on the body, collect glucose measurements. Continuous subcutaneous insulin infusion (CSII) devices are attached to the body via an infusion set and are now available as tubing-free patch pumps that are attached directly to the skin via a catheter. Glucose-responsive insulin delivery systems combine the sensing and delivery features of the other two types of devices.
Once thought to be rare, reports of skin complications related to diabetes devices have been increasing in recent years, she said. Some reports suggest that at any given time, skin complications may affect as many as one quarter to one half of patients who use these devices, “so this is an important issue,” she emphasized. “Skin reactions are a major factor in device discontinuation, so we as clinicians need to be really proactive about treating these reactions.”
Risk factors for skin complications related to diabetes devices include sensitization to the adhesive used with the devices, as well as prolonged exposure to the device, Dr. Chen said. Younger age also appears to be a risk factor, as is a compromised skin barrier in the area where the device is used.

Why the approval of MiniMed 780G is a ‘quantum leap’ forward
This transcript has been edited for clarity.
There is wonderful news in the field of hybrid closed-loop pump technology because the Medtronic 780G system was just approved. I can’t tell you how happy this makes me because we’ve all been waiting for this seemingly forever and ever. This isn’t just a small upgrade from the 770G. It’s a quantum leap from the 770G to the 780G. The 780G has newer algorithms, a new sensor, and a longer-lasting infusion set.
It’s been used since 2020 in Europe, so we have good data on how well it works. Frankly, I think it works really well. We’ve seen nice improvements in [hemoglobin] A1c, time in range, other glycemic metrics, and patient satisfaction in studies done in Europe.
Now, I’ve never had the system to use in one of my patients. I always say I never know a system until I see it in use in my own patients, but let me tell you what I’ve read.
First, it has something called meal-detection technology with autocorrection boluses every 5 minutes. If this works, it can be a huge win for our patients because the problem my patients have is with mealtime dosing. They often dose late, or they may not dose enough insulin for the carbohydrates. That’s where the issues are.
All these hybrid closed-loop systems, this one included, show that the best improvements in glycemia are overnight. I’m hoping that this one shows some nice improvements in daytime glycemia as well. Stay tuned and I’ll let you know once I’ve been using it.
Next, it has adjustable targets down to 100. This is the lowest target for any hybrid closed-loop system. It has an extended-wear infusion set that lasts for 7 days. This infusion set is already available but works with this new system.
Finally, it has a new sensor. It looks like the old sensors, but it’s the Guardian 4, which requires much fewer finger sticks. Now, I’m not entirely sure about how often one has to do a finger stick. I know one has to do with finger sticking to initiate auto mode, or what they call SmartGuard, but I don’t know whether you ever have to do it again. I know for sure that you have to do it again if you fall out of the automated mode into manual mode. Once you’re in SmartGuard, I believe there are no further finger-stick calibrations required.
If people are already on the 770G system, this is just a software update that is presumably easy to upgrade to the 780G. Now, the physical pieces ... If someone doesn’t already have the Guardian 4 sensor or the extended-wear infusion set, they’ll have to get those. The software update to make the 770G increase to the 780G should just come through the cloud. I don’t know when that’s going to happen.
I do know that preorders for this system, if you want to buy the new physical system, start on May 15. The shipping of the new 780G system should occur in the United States toward the end of this summer.
I’m so excited. I think this is really going to benefit my patients. I can’t wait to start using it and letting patients see how these algorithms work and how they really help patients improve their glucose control.

Statin misinformation on social media flagged by AI
Using artificial intelligence to analyze large amounts of information from social media platforms generated some novel insights into public perceptions about statins, results of a new study show.
The study, which used AI to analyze discussions about statins on the social media platform Reddit, corroborated previously documented reasons for statin hesitancy, including adverse effect profiles and general disenfranchisement with health care.
But it also found novel points of discourse, including linking statins to COVID-19 outcomes and the role of cholesterol, statins, and the ketogenic diet.
“We used AI to tell us what is being discussed about statins on social media and to quantify the information in topics that people think are important,” senior study author Fatima Rodriguez, MD, MPH, Stanford (Calif.) University School of Medicine, said in an interview.
“Some of the themes were surprising to us. While we expected discussion on side effects, we were surprised to see so much discussion refuting the idea that increased levels of LDL were detrimental. There were also a large amount of posts on statin use being correlated to COVID outcomes. Our findings show how widespread this misinformation is,” she said.
“As a preventative cardiologist, I spend a lot of my time trying to get patients to take statins, but patients often rely on social media for information, and this can contain a lot of misinformation. People tend to be more honest on online forums than they are in the doctor’s office, so they are probably asking the questions and having discussions on subjects they really care about. So, understanding what is being discussed on social media is very valuable information for us as clinicians.”
The study was published online in JAMA Network Open.
The researchers analyzed all statin-related discussions on Reddit that were dated between Jan. 1, 2009, and July 12, 2022. Statin- and cholesterol-focused communities were identified to create a list of statin-related discussions. An AI pipeline was developed to cluster these discussions into specific topics and overarching thematic groups.
A total of 10,233 unique statin-related discussions and 5,188 unique authors were identified. A total of 100 discussion topics were identified and classified into six overarching thematic groups: (1) ketogenic diets, diabetes, supplements, and statins; (2) statin adverse effects; (3) statin hesitancy; (4) clinical trial appraisals; (5) pharmaceutical industry bias and statins; and (6) red yeast rice and statins.
Several examples of statin-related misinformation were identified, including distrust of the hypothesis that LDL-C has a causal association with heart disease. Discussions included quotes such as, “I think LDL is pretty much irrelevant. Your HDL and triglycerides are far more important.”
Other topics suggested that certain natural supplements would be an acceptable alternative to statins. Quotes included: “Red yeast rice is a statin basically, by the way,” and “statins are basically mycotoxins and deplete you of fat-soluble nutrients, like coQ10, vit D, K, A and E, and in all likelihood through these depletions worsen cardiovascular health.”
The researchers also looked at temporal trends and found that these sorts of discussions have increased over time.
One of the common themes identified was using the ketogenic diet phenomenon as an argument against increased cholesterol levels being bad for health.
Dr. Rodriguez elaborated: “People think the ketogenic diet is healthy as they lose weight on it. And as it can be associated with a small increase in LDL cholesterol, there was a lot of opinion that this meant increasing LDL was a good thing.”
The researchers also conducted a sentiment analysis, which designated topics as positive, negative, or neutral with regard to statins.
“We found that almost no topic was positive. Everything was either neutral or negative. This is pretty consistent with what we are seeing around hesitancy in clinical practice, but you would think that maybe a few people may have a positive view on statins,” Dr. Rodriguez commented.
“One of the problems with statins and lowering cholesterol is that it takes a long time to see a benefit, but this misinformation will result in some people not taking their medication,” she added.
Dr. Rodriguez noted that in this study AI is augmenting, not replacing, what clinicians and researchers do. “But it is a valuable tool to scan a large volume of information, and we have shown here it can generate new insights that we may not have thought of. It’s important to know what’s out there so we can try and combat it.”
She pointed out that patients don’t read the medical literature showing the benefits of statins but rather rely on social media for their information.
“We need to understand all sorts of patient engagement and use the same tools to combat this misinformation. We have a responsibility to try and stop dangerous and false information from being propagated,” she commented.
“These drugs are clearly not dangerous when used in line with clinical guidelines, and they have been proven to have multiple benefits again and again, but we don’t see those kinds of discussions in the community at all. We as clinicians need to use social media and AI to give out the right information. This could start to combat all the misinformation out there.”

A total of 100 discussion topics were identified and classified into six overarching thematic groups: (1) ketogenic diets, diabetes, supplements, and statins; (2) statin adverse effects; (3) statin hesitancy; (4) clinical trial appraisals; (5) pharmaceutical industry bias and statins; and (6) red yeast rice and statins.
Several examples of statin-related misinformation were identified, including distrust of the hypothesis that LDL-C has a causal association with heart disease. Discussions included quotes such as, “I think LDL is pretty much irrelevant. Your HDL and triglycerides are far more important.”
Other topics suggested that certain natural supplements would be an acceptable alternative to statins. Quotes included: “Red yeast rice is a statin basically, by the way,” and “statins are basically mycotoxins and deplete you of fat-soluble nutrients, like coQ10, vit D, K, A and E, and in all likelihood through these depletions worsen cardiovascular health.”
The researchers also looked at temporal trends and found that these sorts of discussions have increased over time.
One of the common themes identified was using the ketogenic diet phenomenon as an argument against increased cholesterol levels being bad for health.
Dr. Rodriguez elaborated: “People think the ketogenic diet is healthy as they lose weight on it. And as it can be associated with a small increase in LDL cholesterol, there was a lot of opinion that this meant increasing LDL was a good thing.”
The researchers also conducted a sentiment analysis, which designated topics as positive, negative, or neutral with regard to statins.
“We found that almost no topic was positive. Everything was either neutral or negative. This is pretty consistent with what we are seeing around hesitancy in clinical practice, but you would think that maybe a few people may have a positive view on statins,” Dr. Rodriguez commented.
“One of the problems with statins and lowering cholesterol is that it takes a long time to see a benefit, but this misinformation will result in some people not taking their medication,” she added.
Dr. Rodriguez noted that in this study AI is augmenting, not replacing, what clinicians and researchers do. “But it is a valuable tool to scan a large volume of information, and we have shown here it can generate new insights that we may not have thought of. It’s important to know what’s out there so we can try and combat it.”
She pointed out that patients don’t read the medical literature showing the benefits of statins but rather rely on social media for their information.
“We need to understand all sorts of patient engagement and use the same tools to combat this misinformation. We have a responsibility to try and stop dangerous and false information from being propagated,” she commented.
“These drugs are clearly not dangerous when used in line with clinical guidelines, and they have been proven to have multiple benefits again and again, but we don’t see those kinds of discussions in the community at all. We as clinicians need to use social media and AI to give out the right information. This could start to combat all the misinformation out there.”

Study shows higher obesity-related cancer mortality in areas with more fast food
based on data from a new cross-sectional study of more than 3,000 communities.
Although increased healthy eating has been associated with reduced risk of obesity and with reduced cancer incidence and mortality, access to healthier eating remains a challenge in communities with less access to grocery stores and healthy food options (food deserts) and/or easy access to convenience stores and fast food (food swamps), Malcolm Seth Bevel, PhD, of the Medical College of Georgia, Augusta, and colleagues, wrote in their paper, published in JAMA Oncology.
In addition, data on the association between food deserts and swamps and obesity-related cancer mortality are limited, they said.
“We felt that the study was important given the fact that obesity is an epidemic in the United States, and multiple factors contribute to obesity, especially adverse food environments,” Dr. Bevel said in an interview. “Also, I lived in these areas my whole life, and saw how it affected underserved populations. There was a story that needed to be told, so we’re telling it,” he said in an interview.
In a study, the researchers analyzed food access and cancer mortality data from 3,038 counties across the United States. The food access data came from the U.S. Department of Agriculture Food Environment Atlas (FEA) for the years 2012, 2014, 2015, 2017, and 2020. Data on obesity-related cancer mortality came from the Centers for Disease Control and Prevention for the years from 2010 to 2020.
Food desert scores were calculated through data from the FEA, and food swamp scores were based on the ratio of fast-food restaurants and convenience stores to grocery stores and farmers markets in a modification of the Retail Food Environment Index score.
The researchers used an age-adjusted, multiple regression model to determine the association between food desert and food swamp scores and obesity-related cancer mortality rates. Higher food swamp and food desert scores (defined as 20.0 to 58.0 or higher) were used to classify counties as having fewer healthy food resources. The primary outcome was obesity-related cancer mortality, defined as high or low (71.8 or higher per 100,000 individuals and less than 71.8 per 100,000 individuals, respectively).
Overall, high rates of obesity-related cancer mortality were 77% more likely in the counties that met the criteria for high food swamp scores (adjusted odds ratio 1.77). In addition, researchers found a positive dose-response relationship among three levels of both food desert scores and food swamp scores and obesity-related cancer mortality.
A total of 758 counties had obesity-related cancer mortality rates in the highest quartile. Compared to counties with low rates of obesity-related cancer mortality, counties with high rates of obesity-related cancer mortality also had a higher percentage of non-Hispanic Black residents (3.26% vs. 1.77%), higher percentage of adults older than 65 years (15.71% vs. 15.40%), higher rates of adult obesity (33.0% vs. 32.10%), and higher rates of adult diabetes (12.50% vs. 10.70%).
Possible explanations for the results include the lack of interest in grocery stores in neighborhoods with a population with a lower socioeconomic status, which can create a food desert, the researchers wrote in their discussion. “Coupled with the increasing growth rate of fast-food restaurants in recent years and the intentional advertisement of unhealthy foods in urban neighborhoods with [people of lower income], the food desert may transform into a food swamp,” they said.
The findings were limited by several factors including the study design, which did not allow for showing a causal association of food deserts and food swamps with obesity-related cancer mortality, the researchers noted. Other limitations included the use of groups rather than individuals, the potential misclassification of food stores, and the use of county-level data on race, ethnicity, and income, they wrote.
The results indicate that “food swamps appear to be a growing epidemic across the U.S., likely because of systemic issues, and should draw concern and conversation from local and state officials,” the researchers concluded.
Community-level investments can benefit individual health
Dr. Bevel said he was not surprised by the findings, as he has seen firsthand the lack of healthy food options and growth of unhealthy food options, especially for certain populations in certain communities. “Typically, these are people who have lower socioeconomic status, primarily non-Hispanic Black or African American or Hispanic American,” he said “I have watched people have to choose between getting fruits/vegetables versus their medications or running to fast food places to feed their families. What is truly surprising is that we’re not talking about people’s lived environment enough for my taste,” he said.
“I hope that our data and results can inform local and state policymakers to truly invest in all communities, such as funding for community gardens, and realize that adverse food environments, including the barriers in navigating these environments, have significant consequences on real people,” said Dr. Bevel. “Also, I hope that the results can help clinicians realize that a patient’s lived environment can truly affect their obesity and/or obesity-related cancer status; being cognizant of that is the first step in holistic, comprehensive care,” he said.
“One role that oncologists might be able to play in improving patients’ access to healthier food is to create and/or implement healthy lifestyle programs with gardening components to combat the poorest food environments that their patients likely reside in,” said Dr. Bevel. Clinicians also could consider the innovative approach of “food prescriptions” to help reduce the effects of deprived, built environments, he noted.
Looking ahead, next steps for research include determining the severity of association between food swamps and obesity-related cancer by varying factors such as cancer type, and examining any potential racial disparities between people living in these environments and obesity-related cancer, Dr. Bevel added.
Data provide foundation for multilevel interventions
The current study findings “raise a clarion call to elevate the discussion on food availability and access to ensure an equitable emphasis on both the importance of lifestyle factors and the upstream structural, economic, and environmental contexts that shape these behaviors at the individual level,” Karriem S. Watson, DHSc, MS, MPH, of the National Institutes of Health, Bethesda, Md., and Angela Odoms-Young, PhD, of Cornell University, Ithaca, N.Y., wrote in an accompanying editorial.
The findings provide a foundation for studies of obesity-related cancer outcomes that take the community environment into consideration, they added.
The causes of both obesity and cancer are complex, and the study findings suggest that the links between unhealthy food environments and obesity-related cancer may go beyond dietary consumption alone and extend to social and psychological factors, the editorialists noted.
“Whether dealing with the lack of access to healthy foods or an overabundance of unhealthy food, there is a critical need to develop additional research that explores the associations between obesity-related cancer mortality and food inequities,” they concluded.
The study received no outside funding. The researchers and the editorialists had no financial conflicts to disclose.

FROM JAMA ONCOLOGY
Expert discusses which diets are best, based on the evidence
according to a speaker at the annual meeting of the American College of Physicians.
“Evidence from studies can help clinicians and their patients develop a successful dietary management plan and achieve optimal health,” said internist Michelle Hauser, MD, clinical associate professor at Stanford (Calif.) University. She also discussed evidence-based techniques to support patients in maintaining dietary modifications.
Predominantly plant‐based diets
Popular predominantly plant‐based diets include a Mediterranean diet, healthy vegetarian diet, predominantly whole-food plant‐based (WFPB) diet, and a dietary approach to stop hypertension (DASH).
The DASH diet was originally designed to help patients manage their blood pressure, but evidence suggests that it also can help adults with obesity lose weight. In contrast to the DASH diet, the Mediterranean diet is not low-fat and not very restrictive. Yet the evidence suggests that the Mediterranean diet is not only helpful for losing weight but also can reduce the risk of various chronic diseases, including obesity, type 2 diabetes, cardiovascular disease (CVD), and cancer, Dr. Hauser said. In addition, data suggest that the Mediterranean diet may reduce the risk of all-cause mortality and lower the levels of cholesterol.
“I like to highlight all these protective effects to my patients, because even if their goal is to lose weight, knowing that hard work pays off in additional ways can keep them motivated,” Dr. Hauser stated.
A healthy vegetarian diet and a WFPB diet are similar, and both are helpful in weight loss and management of total cholesterol and LDL‐C levels. Furthermore, healthy vegetarian and WFPB diets may reduce the risk of type 2 diabetes, CVD, and some cancers. Cohort study data suggest that progressively more vegetarian diets are associated with lower BMIs.
“My interpretation of these data is that predominantly plant-based diets rich in whole foods are healthful and can be done in a way that is sustainable for most,” said Dr. Hauser. However, this generally requires a lot of support at the outset to address gaps in knowledge, skills, and other potential barriers.
For example, she referred one obese patient at risk of diabetes and cardiovascular disease to a registered dietitian to develop a dietary plan. The patient also attended a behavioral medicine weight management program to learn strategies such as using smaller plates, and his family attended a healthy cooking class together to improve meal planning and cooking skills.
Time‐restricted feeding
There are numerous variations of time-restricted feeding, commonly referred to as intermittent fasting, but the principles are similar – limiting food intake to a specific window of time each day or week.
Although some studies have shown that time-restricted feeding may help patients reduce adiposity and improve lipid markers, most studies comparing time-restricted feeding to a calorie-restricted diet have shown little to no difference in weight-related outcomes, Dr. Hauser said.
These data suggest that time-restricted feeding may help patients with weight loss only if time restriction helps them reduce calorie intake. She also warned that time-restrictive feeding might cause late-night cravings and might not be helpful in individuals prone to food cravings.
Low‐carbohydrate and ketogenic diets
Losing muscle mass can prevent some people from dieting, but evidence suggests that a high-fat, very low-carbohydrate diet – also called a ketogenic diet – may help patients reduce weight and fat mass while preserving fat‐free mass, Dr. Hauser said.
The evidence regarding the usefulness of a low-carbohydrate (non-keto) diet is less clear because most studies compared it to a low-fat diet, and these two diets might lead to a similar extent of weight loss.
Rating the level of scientific evidence behind different diet options
Nutrition studies do no provide the same level of evidence as drug studies, said Dr. Hauser, because it is easier to conduct a randomized controlled trial of a drug versus placebo. Diets have many more variables, and it also takes much longer to observe most outcomes of a dietary change.
In addition, clinical trials of dietary interventions are typically short and focus on disease markers such as serum lipids and hemoglobin A1c levels. To obtain reliable information on the usefulness of a diet, researchers need to collect detailed health and lifestyle information from hundreds of thousands of people over several decades, which is not always feasible. “This is why meta-analyses of pooled dietary study data are more likely to yield dependable findings,” she noted.
Getting to know patients is essential to help them maintain diet modifications
When developing a diet plan for a patient, it is important to consider the sustainability of a dietary pattern. “The benefits of any healthy dietary change will only last as long as they can be maintained,” said Dr. Hauser. “Counseling someone on choosing an appropriate long-term dietary pattern requires getting to know them – taste preferences, food traditions, barriers, facilitators, food access, and time and cost restrictions.”
In an interview after the session, David Bittleman, MD, an internist at Veterans Affairs San Diego Health Care System, agreed that getting to know patients is essential for successfully advising them on diet.
“I always start developing a diet plan by trying to find out what [a patient’s] diet is like and what their goals are. I need to know what they are already doing in order to make suggestions about what they can do to make their diet healthier,” he said.
When asked about her approach to supporting patients in the long term, Dr. Hauser said that she recommends sequential, gradual changes. Dr. Hauser added that she suggests her patients prioritize implementing dietary changes that they are confident they can maintain.
Dr. Hauser and Dr. Bittleman report no relevant financial relationships.

“I like to highlight all these protective effects to my patients, because even if their goal is to lose weight, knowing that hard work pays off in additional ways can keep them motivated,” Dr. Hauser stated.
A healthy vegetarian diet and a WFPB diet are similar, and both are helpful in weight loss and management of total cholesterol and LDL‐C levels. Furthermore, healthy vegetarian and WFPB diets may reduce the risk of type 2 diabetes, CVD, and some cancers. Cohort study data suggest that progressively more vegetarian diets are associated with lower BMIs.
“My interpretation of these data is that predominantly plant-based diets rich in whole foods are healthful and can be done in a way that is sustainable for most,” said Dr. Hauser. However, this generally requires a lot of support at the outset to address gaps in knowledge, skills, and other potential barriers.
For example, she referred one obese patient at risk of diabetes and cardiovascular disease to a registered dietitian to develop a dietary plan. The patient also attended a behavioral medicine weight management program to learn strategies such as using smaller plates, and his family attended a healthy cooking class together to improve meal planning and cooking skills.
Time‐restricted feeding
There are numerous variations of time-restricted feeding, commonly referred to as intermittent fasting, but the principles are similar – limiting food intake to a specific window of time each day or week.
Although some studies have shown that time-restricted feeding may help patients reduce adiposity and improve lipid markers, most studies comparing time-restricted feeding to a calorie-restricted diet have shown little to no difference in weight-related outcomes, Dr. Hauser said.
These data suggest that time-restricted feeding may help patients with weight loss only if time restriction helps them reduce calorie intake. She also warned that time-restrictive feeding might cause late-night cravings and might not be helpful in individuals prone to food cravings.
Low‐carbohydrate and ketogenic diets
Losing muscle mass can prevent some people from dieting, but evidence suggests that a high-fat, very low-carbohydrate diet – also called a ketogenic diet – may help patients reduce weight and fat mass while preserving fat‐free mass, Dr. Hauser said.
The evidence regarding the usefulness of a low-carbohydrate (non-keto) diet is less clear because most studies compared it to a low-fat diet, and these two diets might lead to a similar extent of weight loss.
Rating the level of scientific evidence behind different diet options
Nutrition studies do no provide the same level of evidence as drug studies, said Dr. Hauser, because it is easier to conduct a randomized controlled trial of a drug versus placebo. Diets have many more variables, and it also takes much longer to observe most outcomes of a dietary change.
In addition, clinical trials of dietary interventions are typically short and focus on disease markers such as serum lipids and hemoglobin A1c levels. To obtain reliable information on the usefulness of a diet, researchers need to collect detailed health and lifestyle information from hundreds of thousands of people over several decades, which is not always feasible. “This is why meta-analyses of pooled dietary study data are more likely to yield dependable findings,” she noted.
Getting to know patients is essential to help them maintain diet modifications
When developing a diet plan for a patient, it is important to consider the sustainability of a dietary pattern. “The benefits of any healthy dietary change will only last as long as they can be maintained,” said Dr. Hauser. “Counseling someone on choosing an appropriate long-term dietary pattern requires getting to know them – taste preferences, food traditions, barriers, facilitators, food access, and time and cost restrictions.”
In an interview after the session, David Bittleman, MD, an internist at Veterans Affairs San Diego Health Care System, agreed that getting to know patients is essential for successfully advising them on diet.
“I always start developing a diet plan by trying to find out what [a patient’s] diet is like and what their goals are. I need to know what they are already doing in order to make suggestions about what they can do to make their diet healthier,” he said.
When asked about her approach to supporting patients in the long term, Dr. Hauser said that she recommends sequential, gradual changes. Dr. Hauser added that she suggests her patients prioritize implementing dietary changes that they are confident they can maintain.
Dr. Hauser and Dr. Bittleman report no relevant financial relationships.

Should CGM be used for those without diabetes?
Dallas Waldon doesn’t have diabetes, but she says she benefits from continuous glucose monitoring (CGM). “I’m a huge fan of CGMs and used them before, during, and after my pregnancy, [up to] 6 months postpartum, I’m down 11 pounds from my prepregnancy weight,” said Ms. Waldon, a manager for a land-buying company who lives in El Dorado, Calif.
“CGMs bring a certain level of accountability to what you’re eating. You can’t pretend you didn’t eat that cookie while making the kids’ lunch, or that the latte you had was ‘just coffee,’ ” she said. “You have the hard numbers to answer to, and that makes you think twice before putting anything in your mouth.”
Ms. Waldon is not alone. Although CGMs are typically used by people with type 1 diabetes, and increasingly those with type 2 diabetes, some endocrinologists say they are seeing an increased demand for CGM use from individuals who don’t have diabetes.
This allows users to monitor the glucose level and see how eating and exercise affects it. The companies claim that CGM use will help motivate individuals to eat better and maximize their exercise, and therefore consequently lose weight.
These lifestyle programs typically offer users the FreeStyle Libre (Abbott Laboratories). It uses a coin-sized sensor, generally worn on the upper arm, which lasts 14 days and measures glucose in the interstitial fluid. Users can read their glucose levels via an app on their smartphones as many times a day as they want. The FreeStyle Libre is worn by many people with diabetes and is a simple CGM to use, said Anne Peters, MD, professor of clinical medicine, University of Southern California, Los Angeles.
This growing demand for CGM use among healthy people is driven by an increasing “fascination” for monitoring every bodily function, as can be seen by the popularity of smart devices such as Fitbits and Apple watches, Dr. Peters added. These devices allow users to see their heart rates, review their sleep patterns, and monitor their pulses in real time; a CGM is an extension of that by providing up-to-the-minute glucose monitoring.
‘Everyone wants a CGM’
“Everyone wants a CGM,” Dr. Peters said, noting that even family members of her patients with diabetes are asking for them. She admits that their use can be effective for those who are prediabetic so they can see their glycemic responses to food. For instance, someone who typically eats oatmeal for breakfast may see their blood glucose increase, meaning they might want to lower their carbs.
David Klonoff, MD, medical director of the Diabetes Research Institute, Mills-Peninsula Medical Center, San Mateo, Calif., agrees that there has been an increase in use by people who don’t have diabetes as CGMs offer information they wouldn’t otherwise have access to “without having to prick themselves many times.”
People are using CGMs to monitor how high their blood glucose rises after eating certain foods, the length of time it takes to reach peak levels, and how quickly levels drop, he added. Elite athletes are using CGMs to ensure that they are consuming enough calories to avoid hypoglycemia, Dr. Klonoff said.
David T. Ahn, MD, program director at the Mary & Dick Allen Diabetes Center at Hoag Hospital in Newport Beach, Calif., also believes that the devices can provide useful information. “I find that CGM helps people learn a lot about nutrition and how lifestyle choices like food, activity, and stress impact their own physiology,” he stated.
“For example, comparing glucose spikes after different [types of] meals can deepen people’s understanding of carbohydrates vs. protein, or high glycemic index foods vs. low glycemic index foods,” he continued. “In addition, if a patient chooses to follow a very low-carbohydrate diet and/or an intermittent fasting diet, a CGM can be a powerful tool to measure consistency with that lifestyle choice.”
And for a person without diabetes, wearing a CGM provides a way to have personalized information on other physiologic measures, part of the quantified self movement where users log and track their blood pressure, urine output, and oxygen saturation, among other things, Dr. Klonoff said.
But does knowing all this result in behavioral changes?
Dr. Ahn isn’t sure. “For many people, being able to see glucose excursions throughout the day and after meals can be extremely educational and motivating. But much like the Fitbit or Apple Watch, simply wearing [a CGM] ... does not translate to behavior change. The CGM data patterns in someone without diabetes can start to become predictable over time, leading to a drop-off in utility/adherence after the initial education period,” he said.
Dr. Peters said she too isn’t convinced about the long-term worth of CGM in promoting or sustaining behavioral change, as the “novelty” of tracking may wear off after a few months.
And there’s no scientific proof that CGM use in those without diabetes has any impact.
“While there are many programs that offer coaching with CGM data, we need more studies to determine if this leads to improved outcomes like weight loss and prevention, or delay in the development of diabetes,” said Diana Isaacs, PharmD, BCPS, BCACP, BC-ADM, CDCES, FADCES, FCCP, director of education and training in diabetes technology at Cleveland Clinic Diabetes Center.
A 2019 study published in the Journal of Clinical Endocrinology and Metabolism found that the blood glucose of individuals without diabetes using a CGM was in the “ideal” range between 70 mg/dL and 140 mg/dL 96% of the time. “Their glucose was beautifully controlled,” said Dr. Peters, who was one of the study authors.
Currently there aren’t any studies evaluating patterns among healthy individuals wearing CGMs, Dr. Klonoff noted, but he predicts that those studies will be done in the future to examine metabolic patterns that might contribute to someone developing prediabetes or diabetes.
“More data are needed from studies that focus on individuals at risk for diabetes to better understand the role of CGM in these cases, and how to best interpret and utilize the results,” said Fida Bacha, MD, a diabetes and endocrinology specialist and associate professor of pediatrics at Baylor College of Medicine in Houston.
“If clear metrics are identified to predict the progression to diabetes, then this would be worthwhile for early detection and prevention of the disease,” Dr. Bacha said.
Are CGMs too expensive, and can the information overwhelm some?
The biggest obstacle to many people using CGM is cost. “The main downside of using a CGM without diabetes is cost, since insurance won’t usually cover a CGM if the patient does not have diabetes,” said Marilyn Tan, MD, FACE, chief of the Endocrine Clinic, Stanford Health Clinic, Palo Alto, Calif. “Even for patients with diabetes but not on insulin, CGM coverage can be challenging, as out-of-pocket costs for CGM are variable.”
The lifestyle companies mentioned above charge $139-$399 per month, which covers two CGM sensors, each one good for 14 days. Users need to subscribe to a plan for service and delivery. Additional services such as nutrition counseling may be available at an additional cost. Because CGMs in the United States require a prescription, these companies offer web screening and access to a web-based provider.
If healthy patients feel that the informational value of CGMs is worth the money, then they shouldn’t be discouraged, the experts believe.
“There’s little risk of harm with wearing a CGM,” Dr. Tan said, although she acknowledges that “[t]oo much information can also be overwhelming for some individuals.”
Users need to consult with their clinicians to ensure they understand the readings, Dr. Peters said. “You have to tell them not to overreact if the device reads low [glucose] or not to freak out if they get an alarm.” A high glucose reading, indicating hyperglycemia, can be caused by a steroid injection, or older people may experience a postprandial high after eating, she added. “They need to talk to their healthcare provider to interpret the data especially if they are out of [the ideal glucose] range.”
Dr. Klonoff agreed that there is a risk of people trying to “medicalize” too much information. “If you have a fever, you don’t have to go to a doctor to know you have an infection,” he said.
And the point, he added, is not to obsess over the individual numbers but to look for patterns particularly as predictors of metabolic syndrome. If a patient’s glucose is primarily in range, he or she wouldn’t necessarily worry about diabetes. But if it’s out of range more than 10% of the time, it might mean that patient is at risk for diabetes. “It might be time to counsel the patient to eat healthier and exercise more,” he said. “It’s never wrong to steer people to a healthier lifestyle.”
But another issue is whether the numbers from CGMs are entirely accurate in people without diabetes. A 2020 study published in the American Journal of Clinical Nutrition had 16 adults without diabetes wear both the Dexcom G4 Platinum CGM and Abbott FreeStyle Libre Pro for 28 days.
Researchers found that mean postprandial glucose was higher with the Dexcom than with the Abbott system, suggesting that “postprandial glycemic excursions were somewhat inconsistent between the CGMs.” The authors concluded that it may be too early to personalize meal recommendations via CGM.
Dr. Isaacs said perhaps the happy medium is for those without diabetes to just use CGMs occasionally. “It’s ... unclear [if] the right [use] of CGM needs to be continuous or if periodic use, such as once every 3 months, is enough for benefits,” she concluded.
