Here, a triple agonist that interacts with GLP-1, neuropeptide Y1&Y2 receptors, regulated insulin secretion in rat and human pancreatic islets, promoted insulin-independent Y1-R-mediated glucose uptake in rat muscle tissue ex vivo and reduced food intake and body weight in rats. Image
- Mechanisms underlying long-term sustained weight loss and glycemic normalization after obesity surgery include changes in gut hormone levels, including glucagon-like peptide 1 (GLP-1) and peptide YY (PYY).
- PYY1–36 is a gut hormone that binds to the Y1-R in pancreatic islets and central nervous system nuclei that control appetite regulation in the brain including the brainstem area postrema and nucleus tractus solitarius, where it has an orexigenic effect.

This systematic review and meta-analysis suggests that the dietary resemblance between parents and children are most likely to be weak to moderate for most aspects of dietary intakes.
- There is a strong societal belief that parents are role models for their child's dietary behaviours in early life that may persist throughout the life course.

Evidence has shown inconclusive dietary resemblance in parent-child pairs.
- This systematic review and meta-analysis aimed to examine dietary resemblance between parent and children.

In this one, a higher cardiovascular risk, as assessed by the Framingham 10‐year cardiovascular disease risk score, was associated with poorer cognitive function among older adults living in the US. Image
- The Framingham 10‐year cardiovascular disease risk score is based on age, sex, smoking, total cholesterol, high‐density lipoprotein‐cholesterol, blood pressure, and diabetes.
- It was found to be associated with lower cognitive function among older adults, including overall cognition and particular domains of cognition, such as executive function and processing speed, and immediate and delayed memory.

Using linear and non-linear Mendelian randomization analyses, this one suggests that a higher adiposity, as measured by BMI, is causally associated with an increased risk for rheumatic disease, an effect that is more pronounced in women for both gout and psoriatic arthropathy. Image
- A genetic predisposition to high BMI is was found to be causally linked to a higher risk of developing psoriatic arthropathy and inflammatory spondylitis.
- For psoriatic arthropathy and gout, sex-specific effects were observed, and for osteoarthritis, the effect of BMI was stronger in premenopausal compared to postmenopausal women.

In this one, both an elevated lipid accumulation product (LAP) and an visceral adiposity index (VAI), were associated with an increased risk for early-onset type 2 diabetes among young Chinese adults.
- The lipid accumulation product (LAP) is a marker designed to measure cardiovascular disease risk factors that integrates waist circumference, an indicator of abdominal obesity, and triglyceride levels.
* LAP index (females)=TG (mmol/L)×(WC [cm]−58)

* LAP index (males)=TG (mmol/L)×(WC [cm]−65)

Food addiction is real and is related to #obesity and #diabetes

1. Food #addiction (FA) syndrome can be diagnosed by using Yale Food Addiction Scale (YFAS). There are 11 possible symptoms, which can be used to diagnose FA, as well as grade its severity.
#Diet #MedTwitter Image
2. Clinical diagnosis of food addiction (FA)
Individuals can meet a “diagnostic” score for FA on the current versions of the YFAS by endorsing at least two of the 11 behavioral indicators of addiction plus clinical impairment/distress.
3. Severity of Food addiction
Severity thresholds for this “diagnostic” score are defined by the number of symptoms endorsed
(mild: 2–3 symptoms;
moderate: 4–5 symptoms;
severe: 6–11 symptoms)

In this nationally representative sample of US youths at higher risk for type 2 diabetes due to elevated BMI, risk perception and risk awareness were not found associated with greater engagement in diabetes risk-reducing behaviors.
- Instead, greater diabetes risk perception was associated with more time spent watching TV and fewer days of adequate physical activity, whereas awareness was not associated with reported health behaviors.
- Some health care access barriers, including measures of economic disadvantage, were associated with adverse patterns of health behaviors such as lower levels of physical activity.

Interesting to see anti #obesity and #diabetes #medication management from the perspective of PharmDs

I'm always pro-collaborative care!

Here are some learning points and fact checks:

#AACE2023 #endocrine #endocrinology #pharmacology

- "Tirzepatide is a dual agonist"
👉It ↑GIP activity but GLP-1R agonism is less than that of endogenous GLP-1
- "Hypoglycemia is not a concern if you're not on insulin"
👉Risk of hypoglycemia ~1.4% vs. 0.2% in placebo in SURMOUNT-1…

- "In this pt with uncontrolled #diabetes, A1c 7.4, we decreased glargine by 10% [when we started tirzepatide]"

👉 Not sure where the evidence is here, but the SURPASS-5 trial protocol reduced basal by 20% in participants with baseline A1c<8…

👉Reduce #WeightStigma
The bidirectional relationship between #weightbias and #obesity is unequivocal

I'm moved by the enormous consensus among multiple professional societies, MDs PhDs MPHs experts etc, on how important this is

Details you might not know:
- Groups were not matched for type of sugar
- No hint of a difference in insulin sensitivity between groups based on OGTT results
- Groups were not matched for beverage amount (and implication for speed of food intake)

@scottkahan up next, challenging us to challenge our own #weightbias


1/ Image
For example:

Are you asking patients to "try lifestyle changes" first before referring them to specialty care? (eg, endocrinology, bariatric surgery)

This is a subtle example of #weightbias
(Assuming they haven't tried already)

Dr. Rudy Leibel of @ColumbiaMed, everyone Image
Key quote:
"The RISK of developing obesity comes from genes."

Note that he doesn't say obesity itself is caused by genes. This would be an oversimplification!

You've seen this graph in several versions. This is what happens when genes set a risk level and the environment selects for it, resulting in a specific phenotype

Paper from the @IAEANA group @NatMetabolism , this one led by @JohnSpeakman4 tracking changes in daily expenditure over the past 40 years. Some fun stuff to unpack! 1/…
One possible reason for the #obesity pandemic is ⬇️expenditure. @WHO for example cites "physical inactivity due to the increasingly sedentary nature of many forms of work" as a major cause of obesity. But has Activity Expenditure really declined? 2/…

In this one, obesity, but not overweight, was associated with a higher risk of death from middle to older age, irrespective of the adiposity index used, suggesting that obesity should be prevented across the lifespan, including in individuals up to 85 years of age. Image
- Lower risk of mortality in older participants with overweight compared with normal weight when adiposity was assessed by the fat mass index was observed.
- However, the magnitude of this association was small and probably not clinically meaningful.
