Episode transcript:

Dexcom announces some features of it's next generation CGM – the G8. We've been talking about this with CEO Jake Leach for a while now – it will be a 50% smaller with what they're calling advanced sensing capabilities.

According to Leach, G8 will adapt to the physiologic variability of each user. It has additional technology built in, based on a new silicon chip design and algorithm. 15 day wear is now the baseline for all Dexcom sensors moving forward.

At launch the G8 will only measure glucose but the plan is for a multi-analyte version to follow. That would measure ketones and potassium. Ketones we know – but potassium is very important for people with kidney and possible for people taking some diabetes meds. It's an interesting space to watch.. btw, analyte is just a medical word for the specific thing you're measuring – the target of the test you're running. we're going to hear that word a lot I think..

Looks like an FDA submission for the G8 next year.. with an outside the US launch the following year.

Glucotrack has submitted its implantable continuous blood glucose monitor (CBGM) for FDA IDE, that's investigational device exemption and would enable the company to initiate a U.S. clinical study for the fully implantable technology.

Rutherford, New Jersey-based Glucotrack's device features no on-body external component. The company aims to offer it for three years of continuous, accurate blood glucose monitoring for a more convenient, less intrusive solution. Unlike traditional CGMs that measure glucose in interstitial fluid, the CBGM measures glucose levels directly from the blood.

The implant goes five centimeters within the subclavian vein. Glucotrack's active implantable device has a small battery and some electronics that go just under the skin in the pectoral region. The location of the implant is not in a major vessel, but the implant can measure real-time glucose levels as pulsatile blood flows over the tip of the sensor.

PharmaSens today announced the publication of data from the first clinical study evaluating its all-in-one insulin patch pump offering.

The all-in-one pump pairs the Niaa Essential insulin patch pump with the SynerG continuous glucose monitor (CGM) sensor developed by Pacific Diabetes Technologies.

However, this system would be one device that features both the pump and CGM technology.

PharmaSens and SiBionics also have a collaboration aimed at developing the all-in-one solution. They are jointly developing the next-generation Niia insulin patch pump with a SiBionics CGM. PharmaSens expects a second feasibility study in the second quarter to evaluate the next-generation pump with SiBionics' CGM.

PharmaSens says the clinical feasibility study of Niia demonstrated for the first time ever that the combined offering is, in fact, feasible. It believes its device addresses the need for alternatives to multi-device diabetes management. systems.

Aggregated MARD for the investigational device came in at 11.6%. A MARD target of less than 10% is considered ideal for CGM devices, but PharmaSens said that, in the context of the early feasibility study, the results were encouraging and provide evidence supporting the development of an all-in-one system.

Diabeloop just got CE Mark approval for DBLG2 integrations – it's latest AID platform

the company has kicked off the gradual European launch of the technology. It currently offers DBLG2 as a smartphone application on Android, with iOS integration coming soon.

As you just heard, it's integrated with kaleido and the company says it plans to make additional configuration for DBLG2 with alternative pumps "available soon."

Running on a user's smartphone, DBLG2 works as a self-learning algorithm. It continuously analyzes glucose data, calculates insulin needs in real time and automatically adjusts delivery.

Among adults with type 1 diabetes (T1D), the initiation of GLP-1-based therapy was associated with a lower risk for all-cause death, several cardiovascular outcomes, all-cause hospitalisations, and hypoglycaemia, without a higher risk for diabetic ketoacidosis.

METHODOLOGY:

Researchers in Greece conducted a retrospective cohort study utilising real-world data from a global health research network to evaluate the association between GLP-1-based therapy and cardiovascular and renal outcomes in adults with T1D.

A total of 4088 patients receiving GLP-1-based therapies (median age, 43 years; 34.3% men) were propensity score matched with an equal number of patients not receiving the treatment.

The risk for hypoglycaemia was lower with GLP-1-based therapy (hazard ratio, 0.72; P = .021); however, the risk for diabetic ketoacidosis did not differ significantly between the two groups.

Eli Lilly and Company (NYSE: LLY) today announced detailed results from two late-phase trials showing that people with obesity maintained their weight loss long term with either Foundayo or lower-dose Zepbound after switching from higher doses of injectable incretin therapy. The findings from SURMOUNT-MAINTAIN and ATTAIN-MAINTAIN, were presented at the 33rd European Congress on Obesity (ECO) and published in The Lancet and Nature Medicine, respectively.

"Weight regain remains one of the biggest challenges in obesity care, and is often the result of treatment interruptions that cause biology to work against patients, undoing the progress they've made," said Louis J. Aronne, M.D., FACP, DABOM, founder and Chair Emeritus of the American Board of Obesity Medicine, former president of The Obesity Society, Fellow of the American College of Physicians, world-renowned obesity specialist and Lilly consultant. "These medicines can be used for long-term maintenance today, and results from SURMOUNT-MAINTAIN and ATTAIN-MAINTAIN provide additional evidence of their potential when switching from higher doses of injectable incretin therapy."

Scientists in Sweden have developed a more reliable way to create insulin-producing cells from human stem cells. These lab-grown cells not only respond strongly to glucose but were also able to restore blood sugar control when transplanted into diabetic mice.

When transplanted into diabetic mice, the cells gradually restored the animals' ability to regulate blood sugar. Long way to go, as we say with most of these mice studies.

Interesting look at how the body controls sugar storage – apparently this finding challenges long-standing biology concepts and could open new directions for disease treatment.

Published in Nature, the study describes a potential method for directly reducing glycogen, the stored form of sugar in the body.

These scientists discovered that glycogen can be directly regulated by ubiquitin, a protein best known for marking damaged proteins for recycling or removal.

The study is the first to show that ubiquitin can regulate glycogen in humans, overturning more than 50 years of scientific understanding.

Excess glycogen is also associated with more common health problems, including diabetes, obesity, liver disease, and heart disease.

A new Oklahoma law will give parents the option to have their children screened for Type 1 Diabetes.

The measure passed with overwhelming bipartisan support in the Legislature and takes effect Nov 1. Oklahoma consistently ranks among the states with the highest rates of diabetes and diabetes-related deaths.

The law gives parents access to antibody testing that can detect risk years before symptoms develop, helping families take preventive action and avoid emergency room visits.

More to come including a new study trying to figure out why some people are more likely to develop diabetes, a look at cannabis and preventing metabolic disorders, and

A National Institutes of Health (NIH)-funded study has identified key differences in human pancreatic islet cells that may help explain why some people are more likely to develop diabetes. Researchers found that the mix of hormone-producing cells in the pancreas varies widely from person to person, and that variation plays a central role in how the body regulates blood sugar.

The study involved a deep dive into islet cell function that is linked to donor traits associated with observable characteristics, or phenotype, such as sex, race and ethnicity, as well as genetic information, or genotype, including predicted ancestry and genetic risk for both type 1 and type 2 diabetes.

The findings highlight that islet cell composition, rather than the physical size and shape of islets, is a key factor in regulating hormone release. The team found that the makeup of pancreatic islets plays a major role in how effectively they release insulin and glucagon — key hormones that regulate blood glucose. Islets with a higher proportion of insulin-producing beta cells showed stronger insulin secretion in response to various stimuli, while higher levels of alpha and delta cells were generally linked to reduced insulin output.

In addition, the researchers found that islet hormone secretion is affected by donor traits, such as sex, race and ethnicity and their genetic makeup, including ancestry predicted from genetic testing and genetic risk for type 2 diabetes. Combined, the findings of the study have significant implications for understanding the factors that may predispose people to diabetes.

"This study is the tip of the iceberg," said Dr. Evans-Molina. "We hope this dataset becomes useful to the entire diabetes research community and that researchers use it to answer questions about the genotype-phenotype correlation within these data."

Research published recently in JAMA Network Open offers illuminating evidence suggesting there is a positive association between GLP-1 agonists—drugs commonly used to treat obesity and diabetes—and better outcomes among breast cancer patients.

"This study suggests that GLP-1 drugs may offer protective benefits potentially improving survival and recurrence risk in some female patients with breast cancer – whether this is related to weight control, improve cardiovascular health or other mechanisms remains to be studied," said study senior author Bernard F. Fuemmeler, Ph.D., MPH, associate director for population sciences and the Gordon D. Ginder, M.D., Chair in Cancer Research at VCU Massey Comprehensive Cancer Center.

Breast cancer patients who are also obese or have type 2 diabetes experience more aggressive cancer growth and worse outcomes. Prior studies have shown that weight loss treatment and surgery following a breast cancer diagnosis are associated with improved heart health and increased survival.

What are GLP-1 drugs?

Glucagon-like peptide-1 receptor agonists (GLP-1 RAs).

Approved to treat type 2 diabetes in 2005 and weight management in 2021.

Impacts on breast cancer survival and recurrence are still unclear.

Since 2020, the use of these drugs has increased dramatically, where approximately 12% of Americans have used GLP-1s for weight loss, according to a RAND report.

The research findings

Through a retrospective cohort study examining the electronic health records of more than 840,000 breast cancer patients who were diagnosed between 2006 and 2023, the results suggest there is a potential link between GLP-1 RAs and improved outcomes among breast cancer patients who are also obese or have type 2 diabetes.

GLP-1 RA use was associated with an overall lower risk of death from any cause over a 10-year follow-up period among breast cancer patients. Additionally, breast cancer survivors who used GLP1-RAs for diabetes or obesity had a significantly lower risk of their cancer returning over 10 years following their initial treatment.

"Our findings align with emerging preclinical research and contribute to a growing body of literature related to GLP-1 RA use in oncology settings," said study lead author Kristina L. Tatum, PsyD, MS, of the VCU School of Public Health.

What's next?

Further studies are needed to understand the biological mechanisms, if any, between GLP-1 RAs and breast cancer outcomes. The research team intends to further evaluate these correlations through randomized clinical trials.

"Our study underscores the potential of GLP-1 RAs as an adjunct strategy for improving cancer-related outcomes among patients with breast cancer, although clinical trials are needed to inform effective therapeutic approaches and clinical decision making," Fuemmeler said.

Researchers at UC Riverside gave cannabis to obese mice and found that not only did the rodents lose weight, but when given a concentrated cannabis oil, the mice also saw striking benefits in their metabolic function.

DiPatrizio said his team studied the issue to better understand why cannabis users show significant reductions in weight and risk for diabetes compared with nonusers.

"We would think that chronic cannabis users would be eating more and weigh more, but it's just the opposite," DiPatrizio said.

Scientists are increasingly examining the possibility that cannabis compounds could fight obesity or metabolic disorders like diabetes. Cannabinoids interact with the body's endocannabinoid system, which partially controls nearly every aspect of our physiology, including metabolism and appetite. That creates the possibility that targeting this widespread system could unlock new therapies for these conditions.

A new campaign launched by diaTribe and Genentech aims to empower and educate people about diabetes-related eye disease. Here's what you can do today to protect your eye health. To help address these barriers, diaTribe and Genentech partnered to launch All Eyes on DME, a new campaign that aims to spread awareness and educate people at-risk for or living with diabetes-related eye conditions like DME. Also partnering in the campaign is actor and comedian Damon Wayans, who wanted to share his journey (and, of course, a joke or two) with type 2 diabetes to open up the conversation about what is often a stigmatized or less talked about topic: eye health and diabetes.

One of these important conversations happened recently at the All Eyes on DME launch in New York City, where Wayans joined a panel of experts, advocates, and people living with DME to talk about diabetes-related eye disease and how to help prevent it.
