Q

What is the “Egregious Eleven” model, and how is it different from the previous model?

A

It is a beta-cell-centric construct, that says that the beta cell is the “common denominator” for beta cell damage. There a lot of factors that effect beta cell function and mass, but the main cause of diabetes is dysfunction of the beta cells, whether it is because of insulin resistance or beta-cell destruction. The old model focused on hyperglycemia as the main cause of diabetes.

Q

What are the “egregious eleven?”

A
  1. Pancreatic beta cells
  2. Decreased incretin effect
  3. alpha-cell defect, increased glucagon
  4. Adipose (increased lipolysis)
  5. Muscle (decreased peripheral muscle uptake)
  6. Liver (increased glucose production)
  7. Brain (increased appetite, decreased morning DA surge, increased sympathetic tone)

Q

After a DM screening, if a patient comes back pre-diabetic, what should you do?

A
  • Refer to a DM prevention program (goals to achieve and maintain 7% weight loss, 150 min physical activity per week)
  • Consider metformin for prevention of DM (particularly BMI >35, age >60, GDM, rising A1C w/ lifestyle interventions)
  • Monitor annually for development of DM
  • Screen and treat modifiable risk factors for CVD
18
Q

They are guidelines, but it is important to individualize the plan to the patient.

29
Q

When would someone need a more stringent or less stringent A1C goal?

A

More stringent:

  • DM advanced complications
  • Extensive comorbidities
  • Uncontrolled, longstanding DM and interventions
30
Q

What are the blood pressure goals for someone with DM?

A

31
Q

What is recommended if BP is

1) >120/80
2) >140/80
3) >160/100

A

1) Lifestyle modifications
2) Lifestyle mods + single therapy
3) Lifestyle mods + combo therapy

32
Q

What kinds of lifestyle mods can you do for BP control wth DM?

A

A

W/ albuminuria:

W/o albuminuria:
- ACE-I/ARB

Multiple drug therapy may be needed to achieve goal

34
Q

What do statins do in those w/ DM?

A
  • Treat increased risk of lipid abnormalities that are present in T2DM pts (LDL cholesterol lowering)
  • Treat high risk of ASCVD (cardioprotective)
35
Q

If a DM pt has ASCVD, what statin intensity would they use?

If a DM pt does not have ASCVD, what intensity of statin would they use?

A

w/ ASCVD - high intensity unless over age 75 or not a candidate

w/o ASCVD: depends on 10-yr risk score. If 7.5% or higher, than use high-intensity. If score is lower than 7.5%, use moderate intensity statin.

36
Q

If a person is intolerant of statins, what medication is usually added on?

A

Ezetimibe plus moderate-intensity statin.

37
Q

What are the high-intensity statins? On average, how much do they lower LDL if given daily?

A

Atorvastatin 40-80mg
Rosuvastatin 20-40mg

Lower LDL by about >50%

38
Q

If taken daily, what percentage do moderate-intensity statins generally decrease LDL by?

A

30-50%

39
Q

What percentage do low-intensity statins decrease LDL by?

A

<30%

40
Q

When would you consider aspirin therapy in DM patients?

A

Primary prevention: Consider in either T1DM or T2DM who are at increased cardiovascular risk.
- Most men/women >50 w/ at least one major risk factor (smoking, ASCVD, hypertension, dyslipidemia, albuminuria)

Secondary prevention in diabetic adults with ASCVD
(if aspirin allergy, use clopidogrel)

Over a certain age, aspirin is not recommended
