Diabetes

AMSTERDAM – Systematic screening by primary care physicians for cardiovascular disease (CVD) in high-risk adults – those with type 2 diabetes, chronic obstructive pulmonary disease (COPD), or both – more than doubled the rate of incident CVD diagnosed, compared with usual care, in a Dutch study involving more than 1,200 people and 25 primary care practices.

Scaling up this program to larger populations could potentially uncover huge numbers of currently unrecognized people with CVD given the large number of adults with type 2 diabetes plus those with COPD, Amy Groenewegen, MD, said at the annual congress of the European Society of Cardiology.

“I think this screening is ready for routine use, but it could be followed by prospective studies that investigate whether it produces more benefits in patient-centered outcomes,” Dr. Groenewegen said in a press briefing. She stressed that it has not yet been clearly proven that patients with these chronic diseases are better off long term when their CVD is detected sooner using the tested approach.

“We need simple ways to identify relevant patients for additional screening and potential treatment” of CVD, commented Lars Kober, MD, designated discussant at the Congress and a cardiologist and professor at Rigshospitalet, Copenhagen University Hospital.
 

A ‘very simple’ symptom questionnaire

The study is important because it tested a “very simple” symptom questionnaire as the initial screening phase, yet resulted in a CVD diagnostic rate that was two- to threefold higher than in the control patients managed with usual care, Dr. Kober noted.

The Reviving the Early Diagnosis of CVD (RED-CVD) trial randomized 14 primary care practices in the Netherlands to apply a structured screening protocol to adults with type 2 diabetes or COPD, and another 11 practices that served as controls and provided their patients with usual care.

The study included 624 people in the screening arm and 592 in the usual-care arm. Their average age was about 68 years. In the screening arm, 87% had type 2 diabetes and 20% had COPD, including 6.3% with both. In the usual-care arm, 86% had type 2 diabetes, 21% had COPD, with 7.4% having both.

About a quarter of the study cohort had a history of a CVD diagnosis, but they were included for their potential for developing another form of CVD. The study considered three types of CVD: coronary artery disease, heart failure, and atrial fibrillation.

The CVD screening protocol began with an 11-question survey, completed by patients, that asked about their symptoms. The survey was devised by a research team at the University Medical Center Groningen, the Netherlands, who collaborated on the study.

The second phase for people who had suggestive symptoms was a physical examination, measurement of serum N-terminal pro-brain natriuretic peptide (elevated levels signal incident heart failure), and an ECG. People who continued to show findings consistent with CVD in this phase were then referred on a discretionary basis by the attending physician to a specialist.
 

More than doubling the CVD diagnosis rate

The screening program produced a total of 50 new CVD diagnoses in the screening cohort (8%) and 18 in the control, usual-care arm (3%), for the study’s primary endpoint. The greatest number of events involved heart failure, followed by coronary disease.

The screening questionnaire identified 70% of the people who completed it with suggestive symptoms, such as shortness of breath, claudication, or palpitations. The follow-up assessments of phase two narrowed the group with possible new CVD down to 44% of the people in this arm, and the participating physicians referred 39% to a specialist.

An analysis that adjusted for several demographic and clinical variables and excluded nonobstructive coronary disease as a new CVD diagnosis showed that the systematic screening approach resulted in 2.4-fold more new diagnoses than usual care, reported Dr. Groenewegen, an epidemiologist at University Medical Center Utrecht, the Netherlands.

RED-CVD received no commercial funding. Dr. Groenewegen disclosed no relevant financial relationships. Dr. Kober has received honoraria from AstraZeneca, Bayer, Boehringer Ingelheim, Novartis, and Novo Nordisk.

The Food and Drug Administration has granted two new clearances to Welldoc’s BlueStar digital health platform to enable personalized insulin dosing recommendations for people with type 1 or type 2 diabetes.

The latest clearance, announced on Aug. 23, enables the app-based platform to provide bolus insulin dose recommendations that are based on glucose and trend data from a compatible continuous glucose monitoring (CGM) device. On Aug. 15, the FDA cleared the BlueStar to use connected insulin dosing data in personalized bolus insulin dosing recommendations.

“Welldoc is the first company to receive clearance for a CGM-informed bolus calculator specifically designed for adults who manage their diabetes with multiple daily injections of insulin,” according to a company statement.

“With this clearance, Welldoc is filling a significant gap for people who require complex insulin regimens. By connecting directly with CGM data and using both glucose values and trend arrows, the BlueStar solution will provide precise and in-the-moment insulin dosing guidance directly to individuals, helping them reach their glucose targets,” endocrinologist Grazia Aleppo, MD, of Northwestern University, Chicago, said in the statement.

The new features extend the platform’s existing digital diet and lifestyle coaching capabilities. Previous FDA clearances included expansions to use most types of available insulins, including bolus and premixed insulin titration for patients with type 2 diabetes, in September 2021 and for basal insulin adjustment in June 2020.

Dr. Aleppo was a principal investigator in Welldoc’s clinical validation study for BlueStar.

People on Medicare may in 2026 see prices drop for 10 medicines, including pricey diabetes, cancer, blood clot, and arthritis treatments, if advocates for federal drug-price negotiations can implement their plans amid tough opposition.

The Biden administration on Aug. 29 revealed the first 10 drugs selected for direct Medicare price negotiations in accordance with a process mandated by the Inflation Reduction Act of 2022.

It’s unclear at this time, though, how these negotiations will play out. The Chamber of Commerce has sided with pharmaceutical companies in bids to block direct Medicare negotiation of drug prices. Many influential Republicans in Congress oppose this plan, which has deep support from both Democrats and AARP.

While facing strong opposition to negotiations, the Centers for Medicare & Medicaid Services sought in its announcement to illustrate the high costs of the selected medicines.

CMS provided data on total Part D costs for selected medicines for the period from June 2022 to May 2023, along with tallies of the number of people taking these drugs. The 10 selected medicines are as follows:
 

• Eliquis (generic name: apixaban), used to prevent and treat serious blood clots. It is taken by about 3.7 million people through Part D plans. The estimated cost is $16.4 billion.
• Jardiance (generic name: empagliflozin), used for diabetes and heart failure. It is taken by almost 1.6 million people through Part D plans. The estimated cost is $7.06 billion.
• Xarelto (generic name: rivaroxaban), used for blood clots. It is taken by about 1.3 million people through Part D plans. The estimated cost is $6 billion.
• Januvia (generic name: sitagliptin), used for diabetes. It is taken by about 869,00 people through Part D plans. The estimated cost is $4.1 billion.
• Farxiga (generic name: dapagliflozin), used for diabetes, heart failure, and chronic kidney disease. It is taken by about 799,000 people through Part D plans. The estimated cost is almost $3.3 billion.
• Entresto (generic name: sacubitril/valsartan), used to treat heart failure. It is taken by 587,000 people through Part D plans. The estimated cost is $2.9 billion.
• Enbrel( generic name: etanercept), used for rheumatoid arthritis, psoriasis, and psoriatic arthritis. It is taken by 48,000 people through Part D plans. The estimated cost is $2.8 billion.
• Imbruvica (generic name: ibrutinib), used to treat some blood cancers. It is taken by about 20,000 people in Part D plans. The estimated cost is $2.7 billion.
• Stelara (generic name: ustekinumab), used to treat plaque psoriasis, psoriatic arthritis, or certain bowel conditions (Crohn’s disease, ulcerative colitis). It is used by about 22,000 people through Part D plans. The estimated cost is $2.6 billion.
• Fiasp; Fiasp FlexTouch; Fiasp PenFill; NovoLog; NovoLog FlexPen; NovoLog PenFill. These are forms of insulin used to treat diabetes. They are used by about 777,000 people through Part D plans. The estimated cost is $2.6 billion.

A vocal critic of Medicare drug negotiations, Joel White, president of the Council for Affordable Health Coverage, called the announcement of the 10 drugs selected for negotiation “a hollow victory lap.” A former Republican staffer on the House Ways and Means Committee, Mr. White aided with the development of the Medicare Part D plans and has kept tabs on the pharmacy programs since its launch in 2006.

“No one’s costs will go down now or for years because of this announcement” about Part D negotiations, Mr. White said in a statement.

According to its website, CAHC includes among its members the American Academy of Ophthalmology as well as some patient groups, drugmakers, such as Johnson & Johnson, and insurers and industry groups, such as the National Association of Manufacturers.

Separately, the influential Chamber of Commerce is making a strong push to at least delay the implementation of the Medicare Part D drug negotiations. On Aug. 28, the chamber released a letter sent to the Biden administration, raising concerns about a “rush” to implement the provisions of the Inflation Reduction Act.

The chamber also has filed suit to challenge the drug negotiation provisions of the Inflation Reduction Act, requesting that the court issue a preliminary injunction by Oct. 1, 2023.

Other pending legal challenges to direct Medicare drug negotiations include suits filed by Merck, Bristol-Myers Squibb, Johnson & Johnson, Boehringer Ingelheim, and AstraZeneca, according to an email from Pharmaceutical Research and Manufacturers of America. PhRMA also said it is a party to a case.

In addition, the three congressional Republicans with most direct influence over Medicare policy issued on Aug. 29 a joint statement outlining their objections to the planned negotiations on drug prices.

This drug-negotiation proposal is “an unworkable, legally dubious scheme that will lead to higher prices for new drugs coming to market, stifle the development of new cures, and destroy jobs,” said House Energy and Commerce Committee Chair Cathy McMorris Rodgers (R-Wash.), House Ways and Means Committee Chair Jason Smith (R-Mo.), and Senate Finance Committee Ranking Member Mike Crapo (R-Idaho).

Democrats were equally firm and vocal in their support of the negotiations. Senate Finance Chairman Ron Wyden (D-Ore.) issued a statement on Aug. 29 that said the release of the list of the 10 drugs selected for Medicare drug negotiations is part of a “seismic shift in the relationship between Big Pharma, the federal government, and seniors who are counting on lower prices.

“I will be following the negotiation process closely and will fight any attempt by Big Pharma to undo or undermine the progress that’s been made,” Mr. Wyden said.

In addition, AARP issued a statement of its continued support for Medicare drug negotiations.

“The No. 1 reason seniors skip or ration their prescriptions is because they can’t afford them. This must stop,” said AARP executive vice president and chief advocacy and engagement officer Nancy LeaMond in the statement. “The big drug companies and their allies continue suing to overturn the Medicare drug price negotiation program to keep up their price gouging. We can’t allow seniors to be Big Pharma’s cash machine anymore.”

This drug-negotiation proposal is “an unworkable, legally dubious scheme that will lead to higher prices for new drugs coming to market, stifle the development of new cures, and destroy jobs,” said House Energy and Commerce Committee Chair Cathy McMorris Rodgers (R-Wash.), House Ways and Means Committee Chair Jason Smith (R-Mo.), and Senate Finance Committee Ranking Member Mike Crapo (R-Idaho).

Democrats were equally firm and vocal in their support of the negotiations. Senate Finance Chairman Ron Wyden (D-Ore.) issued a statement on Aug. 29 that said the release of the list of the 10 drugs selected for Medicare drug negotiations is part of a “seismic shift in the relationship between Big Pharma, the federal government, and seniors who are counting on lower prices.

“I will be following the negotiation process closely and will fight any attempt by Big Pharma to undo or undermine the progress that’s been made,” Mr. Wyden said.

In addition, AARP issued a statement of its continued support for Medicare drug negotiations.

“The No. 1 reason seniors skip or ration their prescriptions is because they can’t afford them. This must stop,” said AARP executive vice president and chief advocacy and engagement officer Nancy LeaMond in the statement. “The big drug companies and their allies continue suing to overturn the Medicare drug price negotiation program to keep up their price gouging. We can’t allow seniors to be Big Pharma’s cash machine anymore.”

Performing any level of leisure-time physical activity reduces the risk for neuropathy and nephropathy in individuals with type 2 diabetes, by between one-fifth and one third, although the impact on retinopathy is weaker, reveals a cohort study of U.K. individuals.

The research, based on data from more than 18,000 participants in the U.K. Biobank, suggests that the minimal level of self-reported activity to reduce the risk for both neuropathy and nephropathy may be the equivalent of less than 1.5 hours of walking per week.

The results are “encouraging and reassuring for both physicians and patients,” lead author Frederik P.B. Kristensen, MSc, PhD student, department of clinical epidemiology, Aarhus (Denmark) University, said in an interview.

Impact of exercise on microvascular complications in T2D has been uncertain

The authors point out that microvascular complications – such as nerve damage (neuropathy), kidney problems (nephropathy), and eye complications (retinopathy) – occur in more than 50% of individuals with type 2 diabetes and have a “substantial impact” on quality of life, on top of the impact of macrovascular complications (such as cardiovascular disease), disability, and mortality.

Although physical activity is seen as a “cornerstone in the multifactorial management of type 2 diabetes because of its beneficial effects on metabolic risk factors,” the impact on microvascular complications is “uncertain” and the evidence is limited and “conflicting.”

The researchers therefore sought to examine the dose-response association, including the minimal effective level, between leisure-time physical activity and neuropathy, nephropathy, and retinopathy.

They conducted a cohort study of individuals aged 37-82 years from the U.K. Biobank who had type 2 diabetes, which was identified using the Eastwood algorithm and/or an A1c greater than or equal to 48 mmol/mol (6.5%).

Individuals with type 1 diabetes or gestational diabetes were excluded, as were those with major disabling somatic disorders, neurodegenerative diseases, and mental disorders, among others.

Leisure-time physical activity was based on the self-reported frequency, duration, and types of physical activities and was combined to calculate the total leisure time activity in MET-hours per week.

Using the American Diabetes Association/World Health Organization recommendations of 150-300 minutes of moderate to vigorous leisure-time physical activity per week, the researchers determined the recommended moderate activity level to be 150 minutes, (equivalent to 2.5 hours, or 7.5 MET-hours per week).

In all, 18,092 individuals with type 2 diabetes were included in the analysis, of whom 37% were women. The mean age was 60 years.

Ten percent of participants performed no leisure-time physical activity, 38% performed activity below the threshold for moderate activity, 20% performed at the recommended level, and 32% were more active.

Those performing no physical activity were more likely to be women, to be younger, to have a higher body mass index, and to have a greater average A1c, as well as have a more unfavorable sociodemographic and behavioral profile.

Over a median follow-up of 12.1 years, 3.7% of the participants were diagnosed with neuropathy, 10.2% with nephropathy, and 11.7% with retinopathy, equating to an incidence per 1,000 person-years of 3.5, 9,8, and 11.4, respectively.

The researchers found that any level of physical activity was associated with an approximate reduction in the risk for neuropathy and nephropathy.

Multivariate analysis indicated that, compared with no physical activity, activity below the recommended level was associated with an adjusted hazard ratio (aHR) for neuropathy of 0.71, whereas the aHR for activity at the recommended level was 0.73 and that for activity above the recommended level was 0.67.

The aHR for nephropathy, compared with no physical activity, was 0.79 for activity below the recommended level, 0.80 for activity at the recommended level, and 0.80 for activity above the recommended level.

The association between physical activity and retinopathy was weaker, however, at aHRs of 0.91, 0.91, and 0.98 for activity below, at, and above the recommended level, respectively.

The researchers suggest that this lower association could be due to differences in the etiology of the different forms of microvascular complications.

Hyperglycemia is the key driver in the development of retinopathy, they note, whereas other metabolic risk factors, such as obesity, insulin resistance, inflammation, dyslipidemia, and hypertension, play a role in neuropathy and nephropathy.

The associations were also less pronounced in women.

Mr. Kristensen said that this is “an important area that needs to be addressed.”

“While different rates between men and women regarding incidence of type 2 diabetes, metabolic risk factors, complications, and the initiation of, and adherence to, therapy have been found,” he continued, “the exact mechanisms remain unclear. We need a further understanding of sex-differences in metabolic regulation, as well as in material living conditions, social and psychological factors, and access to health care, which may influence the risk of complications.”

Mr. Kristensen added, “Sex differences may be present in more areas than we are aware.”

TOPLINE:

Both short and long sleep durations appear to increase the risk for type 2 diabetes, independent of lifestyle and cardiovascular risk factors, suggests an analysis of a Dutch study.

METHODOLOGY:

• Data on 5,561 participants aged 40–75 years from The Maastricht Study who completed the baseline survey between November 2010 and January 2018 and had full data available were included.
• Sleep duration was assessed as the in-bed time in minutes, using a median of 7 nights’ data from an activPAL3 (PAL Technologies) accelerometer, which is worn on the thigh.
• Glucose metabolism was determined via an oral glucose tolerance test and categorized as prediabetes or type 2 diabetes in line with World Health Organization diagnostic criteria.
• The association between sleep duration and type 2 diabetes was assessed on multivariate logistic regression analysis, taking into account a range of potential confounding factors.

TAKEAWAY:

• The mean age of the participants was 60.1 years, and there was an even split between men and women. In all, 832 had prediabetes and 1,341 type 2 diabetes, and the mean sleep duration was 8.3 hours.
• The results indicated there was a U-shaped relationship between sleep duration and type 2 diabetes, so that both long and short sleep durations increased the risk.
• In the fully adjusted model, a sleep duration of 5 hours was associated with an odds ratio for type 2 diabetes versus 8 hours sleep of 2.9. For a sleep duration of 12 hours, the odds ratio was 1.8.
• The association between sleep duration and diabetes was not significant.

IN PRACTICE:

The results “support the idea that sleep duration could be a relevant risk factor for type 2 diabetes independent of lifestyle risk factors, including diet, physical activity, smoking behavior, and alcohol consumption,” wrote the authors.

“These findings underpin the importance of promoting healthy sleep habits to avoid sleep deprivation,” they added.
 

STUDY DETAILS:

The research was led by Jeroen D. Albers, MSc, department of social medicine, Maastricht (the Netherlands) University, and published in Sleep Health. It is an analysis of The Maastricht Study.

LIMITATIONS:

The study is limited by its cross-sectional nature, particularly because there are “plausible causal paths between sleep duration and type 2 in both directions,” the authors note. The accelerometer used in the study also cannot reliably distinguish between waking and sleeping time in bed, with the potential for misclassification. Daytime naps were also not included, and long-term changes sleep patterns were not measured. In addition, it was not possible to control for some potential confounding factors.

DISCLOSURES:

The Maastricht Study was supported by the European Regional Development Fund via OP-Zuid, the Province of Limburg, the Dutch Ministry of Economic Affairs, Stichting De Weijerhorst, the Pearl String Initiative Diabetes, the School for Cardiovascular Diseases, the School for Public Health and Primary Care, the School for Nutrition and Translational Research in Metabolism, Stichting Annadal, Health Foundation Limburg, and unrestricted grants from Janssen-Cilag, Novo Nordisk, and Sanofi Aventis Netherlands.

AMSTERDAM – The era of guidelines that recommended treatment with either a sodium-glucose cotransporter-2 (SGLT-2) inhibitor or a glucagonlike peptide-1 (GLP-1) receptor agonist in people with type 2 diabetes mellitus and established cardiovascular disease (CVD) ended with new recommendations from the European Society of Cardiology that call for starting both classes simultaneously.

“A key change is that we removed the ‘and-or’ and the ‘either-or’ terms and recommend using both classes simultaneously in patients who are eligible based on their clinical indications and without contraindications or intolerance,” said Darren K. McGuire, MD, at the annual congress of the European Society of Cardiology.

The society’s new guidelines for managing CVD in patients with diabetes, released on Aug. 25 and presented in several sessions at the Congress, also break with the past by calling for starting treatment with both an SGLT-2 inhibitor and a GLP-1 receptor agonist without regard to a person’s existing level of glucose control, including their current and target hemoglobin A1c levels, and regardless of background therapy, added Dr. McGuire, a cardiologist and professor at the UT Southwestern Medical Center in Dallas and a member of the ESC panel that wrote the new guidelines.

Instead, the new guidance calls for starting both drug classes promptly in people diagnosed with type 2 diabetes and established atherosclerotic CVD.

Both the previous ESC guidelines from 2019 as well as the current Standards of Care for 2023 document from the American Diabetes Association call for using one class or the other, but they hedge on combined treatment as discretionary.
 

Different mechanisms mean additive benefits

“With increasing numbers of patients with type 2 diabetes in trials for SGLT-2 inhibitors or GLP-1 receptor agonists who were also on the other drug class, we’ve done large, stratified analyses that suggest no treatment-effect modification” when people received agents from both drug classes, Dr. McGuire explained in an interview. “While we don’t understand the mechanisms of action of these drugs for CVD, we’ve become very confident that they use different mechanisms” that appear to have at least partially additive effects.

“Their benefits for CVD risk reduction are completely independent of their glucose effects. They are cardiology drugs,” Dr. McGuire added.

The new ESC guidelines highlight two other clinical settings where people with type 2 diabetes should receive an SGLT-2 inhibitor regardless of their existing level of glucose control and any other medical treatment: people with heart failure and people with chronic kidney disease (CKD) based on a depressed estimated glomerular filtration rate and an elevated urine albumin-to-creatinine ratio.

Nephropathy was considered by the ESC’s guideline panel to confer risk that is similar to that of established atherosclerotic CVD, Dr. McGuire said.

The guidelines also, for the first time for ESC recommendations, made treatment with finerenone (Kerendia, Bayer) a class 1 level A recommendation for people with type 2 diabetes and CKD.
 

SCORE2-Diabetes risk estimator

Another major change in the new ESC guideline revision is introduction of a CVD risk calculator intended to estimate the risk among people with type 2 diabetes but without established CVD, heart failure, or CKD.

Called the SCORE2-Diabetes risk estimator, it calculates a person’s 10-year risk for CVD and includes adjustment based on the European region where a person lives; it also tallies different risk levels for women and for men.

The researchers who developed the SCORE2-Diabetes calculator used data from nearly 230,000 people to devise the tool and then validated it with data from an additional 217,000 Europeans with type 2 diabetes.

Key features of the calculator include its use of routinely collected clinical values, such as age, sex, systolic blood pressure, smoking status, serum cholesterol levels, age at diabetes diagnosis, hemoglobin A1c level, and estimated glomerular filtration rate.

“For the first time we have a clear score to categorize risk” in people with type 2 diabetes and identify who needs more aggressive treatment to prevent CVD development,” said Emanuele Di Angelantonio, MD, PhD, deputy director of the cardiovascular epidemiology unit at the University of Cambridge (England).

The guidelines say that people who have a low (< 5%) or moderate (5%-9%) 10-year risk for CVD are possible candidates for metformin treatment. Those with high (10%-19%) or very high (≥ 20%) risk are possible candidates for treatment with metformin and/or an SGLT-2 inhibitor and/or a GLP-1 receptor agonist, said Dr. Di Angelantonio during his talk at the congress on the new risk score.

“The risk score is a good addition” because it estimates future CVD risk better and more systematically than usual practice, which generally relies on no systematic tool, said Naveed Sattar, PhD, professor of metabolic medicine at the University of Glasgow (Scotland) and also a member of the guideline-writing panel.

The new risk score “is a reasonable way” to identify people without CVD but at elevated risk who might benefit from treatment with a relatively expensive drug, such as an SGLT-2 inhibitor, Dr. Sattar said in an interview. “It doesn’t rely on any fancy biomarkers or imaging, and it takes about 30 seconds to calculate. It’s not perfect, but it gets the job done,” and it will increase the number of people with type 2 diabetes who will receive an SGLT-2 inhibitor, he predicted.

Dr. Di Angelantonio had no disclosures. Dr. Sattar has been a consultant to Abbott, Amgen, AstraZeneca, Boehringer Ingelheim, Lilly, Novartis, Novo Nordisk, Pfizer, and Roche Diagnostics.

The society’s new guidelines for managing CVD in patients with diabetes, released on Aug. 25 and presented in several sessions at the Congress, also break with the past by calling for starting treatment with both an SGLT-2 inhibitor and a GLP-1 receptor agonist without regard to a person’s existing level of glucose control, including their current and target hemoglobin A1c levels, and regardless of background therapy, added Dr. McGuire, a cardiologist and professor at the UT Southwestern Medical Center in Dallas and a member of the ESC panel that wrote the new guidelines.

Instead, the new guidance calls for starting both drug classes promptly in people diagnosed with type 2 diabetes and established atherosclerotic CVD.

Both the previous ESC guidelines from 2019 as well as the current Standards of Care for 2023 document from the American Diabetes Association call for using one class or the other, but they hedge on combined treatment as discretionary.
 

Different mechanisms mean additive benefits

“With increasing numbers of patients with type 2 diabetes in trials for SGLT-2 inhibitors or GLP-1 receptor agonists who were also on the other drug class, we’ve done large, stratified analyses that suggest no treatment-effect modification” when people received agents from both drug classes, Dr. McGuire explained in an interview. “While we don’t understand the mechanisms of action of these drugs for CVD, we’ve become very confident that they use different mechanisms” that appear to have at least partially additive effects.

“Their benefits for CVD risk reduction are completely independent of their glucose effects. They are cardiology drugs,” Dr. McGuire added.

The new ESC guidelines highlight two other clinical settings where people with type 2 diabetes should receive an SGLT-2 inhibitor regardless of their existing level of glucose control and any other medical treatment: people with heart failure and people with chronic kidney disease (CKD) based on a depressed estimated glomerular filtration rate and an elevated urine albumin-to-creatinine ratio.

Nephropathy was considered by the ESC’s guideline panel to confer risk that is similar to that of established atherosclerotic CVD, Dr. McGuire said.

The guidelines also, for the first time for ESC recommendations, made treatment with finerenone (Kerendia, Bayer) a class 1 level A recommendation for people with type 2 diabetes and CKD.
 

SCORE2-Diabetes risk estimator

Another major change in the new ESC guideline revision is introduction of a CVD risk calculator intended to estimate the risk among people with type 2 diabetes but without established CVD, heart failure, or CKD.

Called the SCORE2-Diabetes risk estimator, it calculates a person’s 10-year risk for CVD and includes adjustment based on the European region where a person lives; it also tallies different risk levels for women and for men.

The researchers who developed the SCORE2-Diabetes calculator used data from nearly 230,000 people to devise the tool and then validated it with data from an additional 217,000 Europeans with type 2 diabetes.

Key features of the calculator include its use of routinely collected clinical values, such as age, sex, systolic blood pressure, smoking status, serum cholesterol levels, age at diabetes diagnosis, hemoglobin A1c level, and estimated glomerular filtration rate.

“For the first time we have a clear score to categorize risk” in people with type 2 diabetes and identify who needs more aggressive treatment to prevent CVD development,” said Emanuele Di Angelantonio, MD, PhD, deputy director of the cardiovascular epidemiology unit at the University of Cambridge (England).

The guidelines say that people who have a low (< 5%) or moderate (5%-9%) 10-year risk for CVD are possible candidates for metformin treatment. Those with high (10%-19%) or very high (≥ 20%) risk are possible candidates for treatment with metformin and/or an SGLT-2 inhibitor and/or a GLP-1 receptor agonist, said Dr. Di Angelantonio during his talk at the congress on the new risk score.

“The risk score is a good addition” because it estimates future CVD risk better and more systematically than usual practice, which generally relies on no systematic tool, said Naveed Sattar, PhD, professor of metabolic medicine at the University of Glasgow (Scotland) and also a member of the guideline-writing panel.

The new risk score “is a reasonable way” to identify people without CVD but at elevated risk who might benefit from treatment with a relatively expensive drug, such as an SGLT-2 inhibitor, Dr. Sattar said in an interview. “It doesn’t rely on any fancy biomarkers or imaging, and it takes about 30 seconds to calculate. It’s not perfect, but it gets the job done,” and it will increase the number of people with type 2 diabetes who will receive an SGLT-2 inhibitor, he predicted.

Dr. McGuire has been a consultant to Altimmune, Applied Therapeutics, AstraZeneca, Bayer, Boehringer-Ingelheim, Intercept, Lexion, Lilly, Merck, New Amsterdam, and Pfizer. Dr. Di Angelantonio had no disclosures. Dr. Sattar has been a consultant to Abbott, Amgen, AstraZeneca, Boehringer Ingelheim, Lilly, Novartis, Novo Nordisk, Pfizer, and Roche Diagnostics.

AMSTERDAM – The era of guidelines that recommended treatment with either a sodium-glucose cotransporter-2 (SGLT-2) inhibitor or a glucagonlike peptide-1 (GLP-1) receptor agonist in people with type 2 diabetes mellitus and established cardiovascular disease (CVD) ended with new recommendations from the European Society of Cardiology that call for starting both classes simultaneously.

A single injection of the GLP-1 receptor agonist liraglutide led to short-term normalization of associative learning in people with obesity and insulin resistance, a finding that suggests dopamine-driven learning processes are modified by metabolic signaling and that this effect “may contribute to the weight-reducing effects of liraglutide in obesity,” say the authors of a recent report in Nature Metabolism.
 

“We demonstrated that dopamine-driven associative learning about external sensory cues crucially depends on metabolic signaling,” said Marc Tittgemeyer, PhD, professor at the Max Planck Institute for Metabolism Research in Cologne, Germany, and senior author of the study. Study participants with impaired insulin sensitivity “exhibited a reduced amplitude of behavioral updating that was normalized” by a single subcutaneous injection of 0.6 mg of liraglutide (the starting daily dose for liraglutide for weight loss, available as Saxenda, Novo Nordisk) given the evening before testing.

The findings, from 30 adults with normal insulin sensitivity and normal weight and 24 adults with impaired insulin sensitivity and obesity, suggest that metabolic signals, particularly ones that promote energy restoration in a setting of energy deprivation caused by insulin or a glucagon-like peptide-1 (GLP-1) receptor agonist, “profoundly influence neuronal processing,” said Dr. Tittgemeyer. The findings suggest that impaired metabolic signaling such as occurs with insulin resistance in people with obesity can cause deficiencies in associative learning.
 

‘Liraglutide can normalize learning of associations’

“We show that in people with obesity, disrupted circuit mechanisms lead to impaired learning about sensory associations,” Dr. Tittgemeyer said in an interview. “The information provided by sensory systems that the brain must interpret to select a behavioral response are ‘off tune’ ” in these individuals.

“This is rather consequential for understanding food-intake behaviors. Modern obesity treatments, such as liraglutide, can normalize learning of associations and thereby render people susceptible again for sensory signals and make them more prone to react to subliminal interactions, such as weight-normalizing diets and conscious eating,” he added.

The normalization in associative learning that one dose of liraglutide produced in people with obesity “fits with studies showing that these drugs restore a normal feeling of satiety, causing people to eat less and therefore lose weight,” he explained.

Dr. Tittgemeyer noted that this effect is likely shared by other agents in the GLP-1 receptor agonist class, such as semaglutide (Ozempic, Wegovy, Novo Nordisk) but is likely not an effect when agents agonize receptors to other nutrient-stimulated hormones such as glucagon and the glucose-dependent insulinotropic polypeptide.

The findings “show that liraglutide restores associative learning in participants with greater insulin resistance,” a “highly relevant” discovery, commented Nils B. Kroemer, PhD, head of the section of medical psychology at the University of Bonn, Germany, who was not involved with this research, in a written statement.

The study run by Dr. Tittgemeyer and his associates included 54 healthy adult volunteers whom they assessed for insulin sensitivity with their homeostasis model assessment of insulin resistance. The researchers divided the cohort into groups; one group included 24 people with impaired insulin sensitivity, and one included 30 with normal insulin sensitivity. The average body mass index (BMI) of the normal sensitivity group was about 24 kg/m²; in the insulin-resistant subgroup, BMI averaged about 33 kg/m².

The associative learning task tested the ability of participants to learn associations between auditory cues (a high or low tone) and a subsequent visual outcome (a picture of a face or a house). During each associative learning session, participants also underwent functional MRI of the brain.
 

Liraglutide treatment leveled learning

The results showed that the learning rate was significantly lower in the subgroup with impaired insulin sensitivity, compared with those with normal insulin sensitivity following treatment with a placebo injection. This indicates a decreased adaptation of learning to predictability variations in individuals with impaired insulin sensitivity.

In contrast, treatment with a single dose of liraglutide significantly enhanced the learning rate in the group with impaired insulin sensitivity but significantly reduced the learning rate in the group with normal insulin sensitivity. Liraglutide’s effect was twice as large in the group with impaired insulin sensitivity than in the group with normal insulin sensitivity, and these opposing effects of liraglutide resulted in a convergence of the two groups’ adaptive learning rates so that there wasn’t any significant between-group difference following liraglutide treatment.

After analyzing the functional MRI data along with the learning results, the researchers concluded that liraglutide normalized learning in individuals with impaired insulin sensitivity by enhancing adaptive prediction error encoding in the brain’s ventral striatum and mesocortical projection sites.

This apparent ability of GLP-1 analogues to correct this learning deficit in people with impaired insulin sensitivity and obesity has implications regarding potential benefit for people with other pathologies characterized by impaired dopaminergic function and associated with metabolic impairments, such as psychosis, Parkinson’s disease, and depression, the researchers say.

“The fascinating thing about GLP-1 receptor agonists is that they have an additional mechanism that relates to anti-inflammatory effects, especially for alleviating cell stress,” said Dr. Tittgemeyer. “Many ongoing clinical trials are assessing their effects in neuropsychiatric diseases,” he noted.

The study received no commercial funding. Dr. Tittgemyer and most of his coauthors had no disclosures. One coauthor had several disclosures, which are detailed in the report. Dr. Kroemer had no disclosures.

Apple cider vinegar and fenugreek seeds are the most effective at reducing fasting blood glucose and hemoglobin A1c levels, compared with four other popular herbal remedies for type 2 diabetes, a recent systematic review found.

The review included 44 randomized clinical trials with more than 3,000 participants using six herbal remedies: apple cider vinegar, cinnamon, curcumin, fenugreek seeds, ginger, and saffron.

Apple cider vinegar, fenugreek seeds, curcumin (turmeric), and cinnamon resulted in statistically significant reductions in fasting blood glucose, compared with the control groups in the clinical trials. Out of all the remedies, the authors found apple cider vinegar to be the most effective for lowering fasting blood glucose levels.

The review also found that apple cider vinegar and fenugreek seeds had a statistically significant effect on reducing A1c, compared with the control groups. The authors found the herbal remedies made no difference to insulin level or homeostatic model assessment for insulin resistance (HOMA-IR).

The results are published online in Diabetes & Metabolic Syndrome: Clinical Research & Reviews. The authors said they hoped the review would help medical professionals and people with type 2 diabetes understand the effectiveness of different herbal remedies and consider incorporating these remedies into standard care.

“Some people use curcumin, some use ginger, some use apple cider [vinegar], but it’s not clear which is better,” said Shiv Mudgal, PhD, corresponding author of the paper and an associate professor in nursing at the All India Institute of Medical Sciences in Deoghar, India.

“We thought it would be nice to get some idea about how they work and how they compete with each other,” said Subodh Kumar, MD, the first author and an associate professor in pharmacology at the All India Institute of Medical Sciences in Deoghar, India.

They wanted to understand how the herbal remedies worked by including insulin level and HOMA-IR as measurable outcomes but found nothing conclusive. Instead, they speculated that the effect of apple cider vinegar and fenugreek seeds on blood glucose and A1c could be related to delayed gastric emptying, among other mechanisms.

However, the results should be interpreted with caution, said Dr. Kumar.

Apple cider vinegar had three clinical trials to back the finding, and fenugreek seeds had four studies supporting the results – fewer than the other included remedies. The authors also identified risks of bias from the randomization process and the allocation concealment process in several of the included trials.

Most of the studies included only short follow-up periods, meaning that the long-term effects of using these herbal remedies to help manage type 2 diabetes remain unclear.

The six herbal remedies included in the study were chosen out of dozens of popular complementary medicines for the strength and number of clinical trials backing their use.

The limited number included in the review is a drawback, according to Merlin Willcox, DPhil, a clinical lecturer in general practice at the University of Southampton, England, who was not involved in the research.

“It means they’ve left out stuff that’s potentially effective,” Dr. Willcox said in an interview.

Dr. Willcox, who has coauthored a review of herbal remedies for glycemic control in type 2 diabetes, said he was surprised that apple cider vinegar came out on top in this analysis.

His review concluded that aloe vera leaf gel, psyllium fiber, and fenugreek seeds appeared to be the most effective at reducing A1c, compared with the control groups of the included trials, out of 18 plant-based remedies.

There were no adverse effects associated with the herbal remedies, according to Dr. Mudgal. However, the evidence for the herbal remedies included in their review also lacked substantial follow-up periods assessing their long-term effects.

“You need to look at the evidence for each individual remedy; it’s not just about what plant it is, but it’s about what preparation, what dose. All of that comes into play,” Dr. Willcox said.

Up to 3.6 million people use herbal remedies to manage type 2 diabetes in the United States, according to a 2014 study cited by the review authors. The number is much higher elsewhere: As many as two-thirds of patients with diabetes in India and Saudi Arabia incorporate herbal remedies to help manage symptoms, whereas about half of patients with diabetes in the United Kingdom use herbal medicines.

Experts warn of the risks associated with using herbal medicines to complement traditional therapies.

“I caution my patients about dietary supplements and herbals because of the lack of high-quality data demonstrating efficacy and safety,” Katherine H. Saunders, MD, DABOM, cofounder of Intellihealth and clinical assistant professor of medicine at Weill Cornell Medicine, New York, said in an interview.

For Dr. Willcox, the risks relate to where patients get their information from. Many patients with type 2 diabetes are too scared to talk to their doctor about herbal medicines. 

“They think their doctor is going to be negative or dismissive,” Dr. Willcox said. “So patients are getting their information from family and friends or from the Internet, which is not necessarily the most reliable, evidence-based source of information.”

The authors have reported no relevant financial relationships.

“You need to look at the evidence for each individual remedy; it’s not just about what plant it is, but it’s about what preparation, what dose. All of that comes into play,” Dr. Willcox said.

Up to 3.6 million people use herbal remedies to manage type 2 diabetes in the United States, according to a 2014 study cited by the review authors. The number is much higher elsewhere: As many as two-thirds of patients with diabetes in India and Saudi Arabia incorporate herbal remedies to help manage symptoms, whereas about half of patients with diabetes in the United Kingdom use herbal medicines.

Experts warn of the risks associated with using herbal medicines to complement traditional therapies.

“I caution my patients about dietary supplements and herbals because of the lack of high-quality data demonstrating efficacy and safety,” Katherine H. Saunders, MD, DABOM, cofounder of Intellihealth and clinical assistant professor of medicine at Weill Cornell Medicine, New York, said in an interview.

For Dr. Willcox, the risks relate to where patients get their information from. Many patients with type 2 diabetes are too scared to talk to their doctor about herbal medicines. 

“They think their doctor is going to be negative or dismissive,” Dr. Willcox said. “So patients are getting their information from family and friends or from the Internet, which is not necessarily the most reliable, evidence-based source of information.”

Apple cider vinegar and fenugreek seeds are the most effective at reducing fasting blood glucose and hemoglobin A1c levels, compared with four other popular herbal remedies for type 2 diabetes, a recent systematic review found.

The review included 44 randomized clinical trials with more than 3,000 participants using six herbal remedies: apple cider vinegar, cinnamon, curcumin, fenugreek seeds, ginger, and saffron.

Apple cider vinegar, fenugreek seeds, curcumin (turmeric), and cinnamon resulted in statistically significant reductions in fasting blood glucose, compared with the control groups in the clinical trials. Out of all the remedies, the authors found apple cider vinegar to be the most effective for lowering fasting blood glucose levels.

The review also found that apple cider vinegar and fenugreek seeds had a statistically significant effect on reducing A1c, compared with the control groups. The authors found the herbal remedies made no difference to insulin level or homeostatic model assessment for insulin resistance (HOMA-IR).

The results are published online in Diabetes & Metabolic Syndrome: Clinical Research & Reviews. The authors said they hoped the review would help medical professionals and people with type 2 diabetes understand the effectiveness of different herbal remedies and consider incorporating these remedies into standard care.

“Some people use curcumin, some use ginger, some use apple cider [vinegar], but it’s not clear which is better,” said Shiv Mudgal, PhD, corresponding author of the paper and an associate professor in nursing at the All India Institute of Medical Sciences in Deoghar, India.

“We thought it would be nice to get some idea about how they work and how they compete with each other,” said Subodh Kumar, MD, the first author and an associate professor in pharmacology at the All India Institute of Medical Sciences in Deoghar, India.

They wanted to understand how the herbal remedies worked by including insulin level and HOMA-IR as measurable outcomes but found nothing conclusive. Instead, they speculated that the effect of apple cider vinegar and fenugreek seeds on blood glucose and A1c could be related to delayed gastric emptying, among other mechanisms.

However, the results should be interpreted with caution, said Dr. Kumar.

Apple cider vinegar had three clinical trials to back the finding, and fenugreek seeds had four studies supporting the results – fewer than the other included remedies. The authors also identified risks of bias from the randomization process and the allocation concealment process in several of the included trials.

Most of the studies included only short follow-up periods, meaning that the long-term effects of using these herbal remedies to help manage type 2 diabetes remain unclear.

The six herbal remedies included in the study were chosen out of dozens of popular complementary medicines for the strength and number of clinical trials backing their use.

The limited number included in the review is a drawback, according to Merlin Willcox, DPhil, a clinical lecturer in general practice at the University of Southampton, England, who was not involved in the research.

“It means they’ve left out stuff that’s potentially effective,” Dr. Willcox said in an interview.

Dr. Willcox, who has coauthored a review of herbal remedies for glycemic control in type 2 diabetes, said he was surprised that apple cider vinegar came out on top in this analysis.

His review concluded that aloe vera leaf gel, psyllium fiber, and fenugreek seeds appeared to be the most effective at reducing A1c, compared with the control groups of the included trials, out of 18 plant-based remedies.

There were no adverse effects associated with the herbal remedies, according to Dr. Mudgal. However, the evidence for the herbal remedies included in their review also lacked substantial follow-up periods assessing their long-term effects.

“You need to look at the evidence for each individual remedy; it’s not just about what plant it is, but it’s about what preparation, what dose. All of that comes into play,” Dr. Willcox said.

Patients with pregestational diabetes may benefit from use of a continuous subcutaneous insulin infusion pump paired with a continuous glucose monitor. Use of the tools has been associated with a reduction in maternal and neonatal morbidity, a recent study found.

“We were seeing an unacceptable burden of both maternal and fetal disease in our diabetic population,” said Neil Hamill, MD, a maternal-fetal medicine specialist at Methodist Women’s Hospital, Omaha, Neb., and an author of the study. “We thought the success with this technology in the nonpregnant population would and should translate into the pregnant population.”

Dr. Hamill and his colleagues analyzed data from 55 pregnant patients who received care at the Women’s Hospital Perinatal Center at the Nebraska Methodist Health System between October 2019 and October 2022. Everyone in the cohort had pregestational diabetes and required insulin prior to week 20 of pregnancy. They used CGMs for more than 2 weeks. The study set blood glucose levels of less than 140 mg/dL as a healthy benchmark.

Participants who had severe preeclampsia, who had delivered preterm, who had delivered a neonate with respiratory distress syndrome, and/or who had given birth to a larger-than-expected infant spent less time in the safe zone – having a blood glucose level below 140 mg/dL – than women who did not have those risk factors.

“When blood sugar control is better, maternal and fetal outcomes are improved,” Dr. Hamill said.

Neetu Sodhi, MD, an ob.gyn. at Providence Cedars-Sinai Tarzana Medical Center, Los Angeles, expressed optimism that use of blood glucose monitors and insulin pumps can improve outcomes for pregnant patients with pregestational diabetes.

“This is just another case for why it’s so important for patients to have access to these types of devices that really, really improve their outcomes and their health, and now it’s proven in the case of pregnancy outcomes too – or at least suggested strongly with this data,” Dr. Sodhi said.

Mark Ebell, MD, a professor of epidemiology at the University of Georgia, Athens, was more skeptical, pointing out that study participants might have used other methods in addition to the technology to lower their blood sugar levels.

The findings suggest that insulin pumps are more manageable than multiple, daily self-injections. About 1 in 9 women have diabetes in the United States, and 35% of people newly diagnosed with the condition are women of reproductive age.

Dr. Hamill said that in future research, use of a stricter criterion for baseline blood sugar levels (< 140 mg/dL) would be helpful, as would exploring how much time patients need to spend below that level for optimal outcomes.

“Those questions are really absent in the literature,” Dr. Hamill said. “Most of our obstetrical literature is comparing treatment types. All those things are secondary. It’s the blood sugar that confers the risk, and if we get the blood sugar better, risk is reduced.”

Dr. Hamill added that the benefits of these technologies for patients with gestational diabetes are unclear in consideration of the limited duration of the disease and the time required to implant or install a monitor and pump, as well as associated risks and the cost of the devices.

Dr. Sodhi said clinicians who see patients during family planning visits should review morbidities and medical problems related to diabetes.

“I think this is a study that’s maybe too early,” Dr. Sodhi said. “They did ‘guesstimates’ on what target blood glucose ranges to be looking at, but I think over time, we might, with more studies like this, be building a case to try to put these types of monitors in for patients who are young for the purpose of optimizing pregnancy outcomes.”

The authors have disclosed no relevant financial relationships.

Doctor, if you are caring for patients with diabetes, I sure hope you know more about it than I do. The longer I live, it seems, the less I understand.

In a free society, people can do what they want, and that’s great except when it isn’t. That’s why societies develop ethics and even public laws if ethics are not strong enough to protect us from ourselves and others.
 

Sugar, sugar

When I was growing up in small-town Alabama during the Depression and World War II, we called it sugar diabetes. Eat too much sugar, you got fat; your blood sugar went up, and you spilled sugar into your urine. Diabetes was fairly rare, and so was obesity. Doctors treated it by limiting the intake of sugar (and various sweet foods), along with attempting weight loss. If that didn’t do the trick, insulin injections.

From then until now, note these trends.

• 1920: 0.2% of the population
• 1930: 0.3% of the population
• 1940: 0.4% of the population

In 2020, although 11.3% of the population was diagnosed with type 2 diabetes, the unknown undiagnosed proportion could be much higher.

Notice a correlation between sugar consumption and prevalence of diabetes? Of course, correlation is not causation, but at the same time, it sure as hell is not negation. Such concordance can be considered hypothesis generating. It may not be true causation, but it’s a good bet when 89% of people with diabetes have overweight or obesity.

What did the entire medical, public health, government, agriculture, nursing, food manufacturing, marketing, advertising, restaurant, and education constituencies do about this as it was happening? They observed, documented, gave lip service, and wrung their hands in public a bit. I do not believe that this is an organized active conspiracy; it would take too many players cooperating over too long a period of time. But it certainly may be a passive conspiracy, and primary care physicians and their patients are trapped.

The proper daily practice of medicine consists of one patient, one physician, one moment, and one decision. Let it be a shared decision, informed by the best evidence and taking cost into consideration. That encounter represents an opportunity, a responsibility, and a conundrum.

Individual health is subsumed under the collective health of the public. As such, a patient’s health is out of the control of both physician and patient; instead, patients are the beneficiaries or victims of the “marketplace.” Humans are frail and easily taken advantage of by the brilliant and highly motivated strategic planning and execution of Big Agriculture, Big Food, Big Pharma, Big Marketing, and Big Money-Driven Medicine and generally failed by Big Government, Big Public Health, Big Education, Big Psychology, and Big Religion.
 

Rethinking diabetes

Consider diabetes as one of many examples. What a terrific deal for capitalism. First, the system spends decades fattening us up; then, it makes massive amounts of money off of the myriad complications of the fattened populace; then it discovers (invents) long-term, very expensive, compelling treatments to slim us down, with no end in sight, and still without ever understanding the true nature of diabetes.

Gary Taubes’s great new book, “Rethinking Diabetes: What Science Reveals About Diet, Insulin, and Successful Treatments,” is being published by Alfred A. Knopf in early 2024.

It is 404 pages of (dense) text, with 401 numbered references and footnotes, a bibliography of 790 references, alphabetically arranged for easy cross-checking, and a 25-page index.

Remember Mr. Taubes’s earlier definitive historical treatises: “Good Calories, Bad Calories” (2007), “Why We Get Fat” (2010), “The Case Against Sugar” (2016), and “The Case for Keto” (2020)?

This new book is more like “Good Calories, Bad Calories”: long, dense, detailed, definitive, and of great historical reference value, including original research information from other countries in other languages. The author told me that the many early research reference sources were available only in German and that his use of generative artificial intelligence as an assistant researcher was of great value.

Nonphysician author Mr. Taubes uses his deep understanding of science and history to inform his long-honed talents of impartial investigative journalism as he attempts to understand and then explain why after all these years, the medical scientific community still does not have a sound consensus about the essence of diabetes, diet, insulin, and proper prevention and treatment at a level that is actually effective – amazing and so sad.

To signal these evolved and evolving conflicts, the book includes the following chapters:

• “Rise of the Carbohydrate-Rich and Very-Low-Carbohydrate Diets”
• “The Fear of Fat and High-Fat Diets”
• “Insulin and The End of Carbohydrate Restriction and Low Blood Sugar”

Yes, it is difficult. Imagine the bookend segments: “The Nature of Medical Knowledge” and “The Conflicts of Evidence-Based Medicine.” There is also a detailed discussion of good versus bad science spanning three long chapters.

If all that reads like a greatly confused mess to you then you’re beginning to understand. If you are a fan of an unbiased explication of the evolution of understanding the ins and outs of scientific history in richly documented detail, this is a book for you. It’s not a quick nor easy read. And don’t expect to discover whether the newest wonder drugs for weight loss and control of diabetes will be the long-term solution for people with obesity and diabetes worldwide.

Obesity and overweight are major risk factors for type 2 diabetes. About 90% of patients with diabetes have either overweight or obesity. Thus, the complications of these two conditions, which largely overlap, include atherosclerotic cardiovascular disease; myocardial infarction; stroke; hypertension; metabolic syndrome; lower-extremity gangrene; chronic kidney disease; retinopathy; glaucoma; cataracts; disabling osteoarthritis; breast, endometrial, colon, and other cancers; fatty liver; sleep apnea; and peripheral neuropathy. These diseases create a major lucrative business for a wide swathe of medical and surgical specialties, plus hospital, clinic, device, pharmaceutical, and food industries.

In summary, we’ve just been through 40 years of failure to recognize the sugar-elephant in the room and intervene with serious preventive efforts. Forty years of fleshing out both the populace and the American medical-industrial complex (AMIC). Talk about a sweet spot. The only successful long-term treatment of obesity (and with it, diabetes) is prevention. Don’t emphasize losing weight. Focus on preventing excessive weight gain, right now, for the population, beginning with yourselves. Otherwise, we continue openly to perpetuate a terrific deal for the AMIC, a travesty for everyone else. Time for some industrial grade penance and a course correction.

Meanwhile, here we are living out Big Pharma’s dream of a big populace, produced by the agriculture and food industries, enjoyed by capitalism after failures of education, medicine, and public health: a seemingly endless supply of people living with big complications who are ready for big (expensive, new) medications to fix the world’s big health problems.

First, the system spends decades fattening us up; then, it makes massive amounts of money off of the myriad complications of the fattened populace; then it discovers (invents) long-term, very expensive, compelling treatments to slim us down, with no end in sight, and still without ever understanding the true nature of diabetes.

Gary Taubes’s great new book, “Rethinking Diabetes: What Science Reveals About Diet, Insulin, and Successful Treatments,” is being published by Alfred A. Knopf in early 2024.

It is 404 pages of (dense) text, with 401 numbered references and footnotes, a bibliography of 790 references, alphabetically arranged for easy cross-checking, and a 25-page index.

Remember Mr. Taubes’s earlier definitive historical treatises: “Good Calories, Bad Calories” (2007), “Why We Get Fat” (2010), “The Case Against Sugar” (2016), and “The Case for Keto” (2020)?

This new book is more like “Good Calories, Bad Calories”: long, dense, detailed, definitive, and of great historical reference value, including original research information from other countries in other languages. The author told me that the many early research reference sources were available only in German and that his use of generative artificial intelligence as an assistant researcher was of great value.

Nonphysician author Mr. Taubes uses his deep understanding of science and history to inform his long-honed talents of impartial investigative journalism as he attempts to understand and then explain why after all these years, the medical scientific community still does not have a sound consensus about the essence of diabetes, diet, insulin, and proper prevention and treatment at a level that is actually effective – amazing and so sad.

To signal these evolved and evolving conflicts, the book includes the following chapters:

• “Rise of the Carbohydrate-Rich and Very-Low-Carbohydrate Diets”
• “The Fear of Fat and High-Fat Diets”
• “Insulin and The End of Carbohydrate Restriction and Low Blood Sugar”

Yes, it is difficult. Imagine the bookend segments: “The Nature of Medical Knowledge” and “The Conflicts of Evidence-Based Medicine.” There is also a detailed discussion of good versus bad science spanning three long chapters.

If all that reads like a greatly confused mess to you then you’re beginning to understand. If you are a fan of an unbiased explication of the evolution of understanding the ins and outs of scientific history in richly documented detail, this is a book for you. It’s not a quick nor easy read. And don’t expect to discover whether the newest wonder drugs for weight loss and control of diabetes will be the long-term solution for people with obesity and diabetes worldwide.

Obesity and overweight are major risk factors for type 2 diabetes. About 90% of patients with diabetes have either overweight or obesity. Thus, the complications of these two conditions, which largely overlap, include atherosclerotic cardiovascular disease; myocardial infarction; stroke; hypertension; metabolic syndrome; lower-extremity gangrene; chronic kidney disease; retinopathy; glaucoma; cataracts; disabling osteoarthritis; breast, endometrial, colon, and other cancers; fatty liver; sleep apnea; and peripheral neuropathy. These diseases create a major lucrative business for a wide swathe of medical and surgical specialties, plus hospital, clinic, device, pharmaceutical, and food industries.

In summary, we’ve just been through 40 years of failure to recognize the sugar-elephant in the room and intervene with serious preventive efforts. Forty years of fleshing out both the populace and the American medical-industrial complex (AMIC). Talk about a sweet spot. The only successful long-term treatment of obesity (and with it, diabetes) is prevention. Don’t emphasize losing weight. Focus on preventing excessive weight gain, right now, for the population, beginning with yourselves. Otherwise, we continue openly to perpetuate a terrific deal for the AMIC, a travesty for everyone else. Time for some industrial grade penance and a course correction.

Meanwhile, here we are living out Big Pharma’s dream of a big populace, produced by the agriculture and food industries, enjoyed by capitalism after failures of education, medicine, and public health: a seemingly endless supply of people living with big complications who are ready for big (expensive, new) medications to fix the world’s big health problems.
