24
Q

True or false

All adults 40 years and over (and ATSI 18 years and older) without obvious comorbidities elevating them to high risk, are at intermediate risk of diabetes.

25
What are the components of the AUSDRISK screen for type 2 diabetes?
Point based scoring system looking at - Age - Sex - ATSI/Islander/Maori - Where you were born - Australia / Asia etc - Family history of diabetes - Previously detected high BSL? - Blood pressure meds? - Smoker? - Daily fruit / veg? - Exercise - 2.5 hours per week? - Waist measurement
26
What patients are considered high-risk for developing diabetes?
> 40 years old AND overweight or obese AUSDRISK > 12 Patients with impaired glucose tolerance test or impaired fasting glucose Established CVD Women who have had GDM High risk race (Indian, Pacific Islanders) Women with PCOS Patients on anti-psychotics
27
What diabetic screening should be offered to patients less than 40 years of age?
None, unless clinically indicated
28
What diabetic screening should be offered to patients at intermediate risk of developing diabetes?
AUSDRISK assessment, every 3 years
29
What diabetic screening should be offered to patients at high risk of developing diabetes?
Fasting BSL | HBa1C
30
How often should patients, with high risk of diabetes, be screened with a fasting BSL and HbA1c?
In general, high risk patients should be screened every three years. Except for patients with impaired glucose tolerance or impaired fasting glucose - should be screened yearly.
31
How is diabetes diagnosed?
Fasting BSL > 7mmol/L OR HbA1C > 6.5% OR 2 hour, post OGTT > 11.1mmol/L In the absence of unequivocal symptomatic hyperglycemia, the diagnosis must be confirmed on a different day by repeat measurement, repeating the same test for confirmation. If the patient has symptomatic hyperglycaemia, then one measurement is enough
32
What is the definition of impaired fasting glucose?
Definition: Fasting BSL between 5.5–6.9 mmol/L
33
What can be done for a patient with impaired fasting glucose?
Screen for diabetes yearly with a HbA1c or OGTT | Provide intensive lifestyle advice
34
What is the significance of impaired fasting glucose?
It is a prediabetic condition. Without lifestyle modification, diabetes may develop. It is a component metabolic syndrome.
35
What is metabolic syndrome?
Elevated waist circumference (values vary for gender and ethnicity) Elevated triglyceride levels ≥1.7 mmol/L Reduced HDL-C <1.0 mmol/L in men <1.3 mmol/L in women Hypertension (>130/85) Elevated fasting glucose - BSL 5.5–6.9 mmol/L
36
What is the significance of metabolic syndrome?
The MetSy identifies patients at an increased risk of CVD, diabetes and CKD. It provides an estimate of relative risk. Patients with MetSy are 2-3 times more likely to develop CVD, CKD or diabetes compared to similar patients who do not have MetSy.
37
How do you manage metabolic syndrome
Intensive lifestyle modification. Consider medications to control BP and dyslipidaemia. Yearly screening for diabetes.
38
When should you start checking lipids in the general population?
Adults > 45 years | ATSI > 35 years
39
What is the target LDL level for primary prevention?
< 2 mmol/L
40
What is the target HDL level for primary prevention?
> 1 mmol/L
41
What is the target TG level for primary prevention?
<2 mmol/L
42
What is the target total cholesterol for primary prevention?
< 4 mmol/L
43
What is impaired glucose tolerance?
Two-hour plasma glucose between 7.8 | and 11.0 mmol/L
44
Who is at high absolute risk of stroke?
High CVD risk Patients with previous stroke Patients with previous TIA Patients with AF and CHADSVASC = 2 or more
45
What is the ABCD2 score?
Risk assessment tool | Predicts stroke risk after a TIA withing 2 days and 90 days.
46
What are the components of the ABCD2 score?
``` Age > 60 (1 point) BP >140/90 (1 point) Clinical features - unilateral weakness (2 point) - speech impairment without weakness (1 point) Duration > 60 minutes (2 points) 10-59 minutes (1 point) Diabetes (1 point) ```
47
A 65 year old diabetic tells you that she had unilateral arm weakness, lasting 60 minutes 2 days ago. What do you do?
Send to hospital. TIA suspected and has an ABCD2 score of 4 or greater. She is at high risk (4% 2 day risk and ~ 8% 90 day risk) of developing a stroke, and will need a workup.
48
A 51 year old male with no comorbidities presents following an episode of slurred speech lasting 15 minutes yesterday. After taking a careful history, you find that this is the first episode, he is normotensive, he does not have AF and his neuro exam is normal. You suspect a TIA. What is his ABCD2 score and what does this mean?
ABCD2 = 2 Low risk 2 day stroke risk is 1% 90 day stroke risk is 3% Could, in theory, be managed as outpatient with urgent CT scan, aspirin and risk factor reduction.
49
Which patients are at high risk of developing CKD?
``` Smokers Obese Family history of kidney failure Diabetes Hypertension ATSI >30 years Established CVD or PVD History of AKI Chronic opioid users Chronic NSAID users ```
50
How do you screen patients for CKD?
BP Urine ACR Perform every 2 years for high risk patients, and yearly in hypertensives or diabetics.
51
What ACR ratio constitutes macroalbuminuria
Males > 25 mg/mmol | Females > 35 mg/mmol
52
What is the definition of stage 1 CKD?
eGFR >90 mL/min/1.73 m2 AND microalbuminuria, proteinuria or haematuria with the presence of structural or pathological abnormalities.
53
What is the definition of stage 2 CKD?
eGFR 60–89 mL/min/1.73 m2 AND microalbuminuria, proteinuria or haematuria with the presence of structural or pathological abnormalities
54
What is the definition of stage 3a CKD?
eGFR 45–59 mL/min/1.73 m2
55
What is the definition of stage 3b CKD?
eGFR 30–44 mL/min/1.73 m2
56
What is the definition of stage 4 CKD?
eGFR 15–29 mL/min/1.73 m2
57
What is the definition of stage 5 CKD?
eGFR <15 mL/min/1.73 m2 (or on dialysis)
