Q

Clincial features of DKA

A

evolves rapidly over 24 hours

  • Dehydration
  • Polyuria + polydipsia, polyphagia
  • Weight Loss - due to fluid loss and loss of muscle and fat
  • Weakness
  • Kussmaul’s Respirations → Hyperventilation of DKA
  • Nausea and Vomiting
  • Abdominal pain
  • signs of volume depletion + fruity odour to breath

Q

SGLT2 managment periop. surgery vs day procedure.

A
  • should be ceased at least 3 days prior to surgery including endoscopy/colonscopy to prevent DKA in the peri-operative period
  • however for gastroscopy and other day procedures → can cease the SGLT2 inhibitor for the day of the procedure. note that fasting should be minimised.

Q

peri-operative manageemnt - all diabetic medication other than sglt2 inhibitors

A

- withhold medication on the morning of the surgery → DOES NOT matter if on the morning of afternoon list

Q

when to recommence diabetic medication? sglt2 vs metformin?

A

SGLT2 → when eating and drinking normally or close to discharge from hospital. if day surgery, reccomence when on full oral intake

Metformin → recommence 24 hours after major surgery

17
Q

Screening of diabetic retinopathy. When? I

A

at diagnosis

18
Q

if no diabetic retinopathy, how often do we screen? what does it depend on?

A

every year: long diabetes 15 years, systemic disease, hba1c >8, ATSI, nonEnglish.
every 2 years everyone else

19
Q

who is at high risk of CVD without absolute cvd risk calculator?

A
  1. Diabetes + Age >60yo
  2. Diabetes with microalbuminuria (urinary ACR >2.5mg in male and >3.5mg in female)
  3. Moderate or Severe CKD → persistent proteinuria or eGFR <45) → Chronic Kidney Disease (CKD)
  4. Previous diagnosis of Familial Hypercholesterolaemia
  5. Systolic Blood Pressure ≥ 180mmHg or Diastolic Blood Pressure ≥ 110 mmHg
  6. Serum Total Cholesterol > 7.5mmol/L
  7. Aboriginal or Torres Strait Islanders adults ≥ 74yo
20
Q

what should high risk patients be treated wtih?

A

lipid lowering and HTN meds

21
Q

who is considered high risk despite AUSDRISK? what does this mean practically?

A
  • People aged ≥40 years who are overweight or obese
  • People of any age with IGT or IFG
  • People with a first-degree relative with diabetes
  • All patients with a history of a cardiovascular event (eg acute myocardial infarction, angina, peripheral vascular disease or stroke)
  • People of high-risk ethnicity/background (eg Pacific Islands, Indian subcontinent)
  • Women with a history of GDM
  • Women with polycystic ovary syndrome (PCOS)
  • People taking antipsychotic medication
  • Aboriginal and/or Torres Strait Islander people - TESTED ANNUALLY FROM 18YO
22
Q

HbA1c number cutoffs and what does this mean?

A

<6 -> recheck in 3 years if indicated
6-6.5 -> retest in 1 year
>6.5 -> repeat Hba1c - likely diabetes

23
Q

Numbers of Fasting blood glucose cutoffs?

A

<5.5 - unlikely
5.5-6.9 - possible -> perform OGTT
>7.0 -> repeat FBG to confirm diabetes

24
Q

numbers for OGTT cutoffs and what does this mean?

A

Fasting Glucose + 2 hr Glucose:
<6.1 + <7.8 -> retest in 3 years
6.1-6.9 + <7.8 -> Impaired fasting glucose
<7.0 + 7.8 - 11.1 -> impaired glucose tolerance
>7 + >11.1 -> diabetes

25

eyes are yearly if increased risk:
1. diabetes >15years
2. hba1c >8
3. ATSI
4. non-english
5. systemic disease
27
Q

Diabetes cycle of care: yearly

A
Hba1c
Lipids
urine ACR
Complication prevention
non-pharm management
28
Q

TEsts for t1dm

A

Consider non-urgent confirmatory tests for glutamic acid decarboxylase (GAD) and/ or insulinoma antigen-2 (IA-2) antibodies.
consider -> plasma c-peptide level

29
Q

Nutritional Supplements following weight management surgery?

  3. Vit D
    Fe and b12 based on bloods
30
Q

A

between 11-14/40

  • papp-a
  • nuchal translucency
31
Q

2nd trimester screening poitns

A

triple test -> beta-hcg, alpha-feto protein, unconjugated estriol
quad test -> triple test + inhibin A

32
Q

Sick Day management points?

A
  • identify underlying cause - intercurrent illness or use of medications such as corticosteroids
  • increase SMBG → monitor 2-4 hourly or more frequently if BGL is low
  • consider insulin commencement for short period of time for persistent and extreme symptomatic hyperglycaemia → may require hospital admission
  • If nausea, vomiting and/or diarrhoea
    • consider ceasing metformin or GLP1 RA as these may aggravate symptoms. (also for SGLT2)
  • Increase fluid intake → to prevent dehydration (if BGL >15 - nonglucose drinks, if BGL <15 - oral rehydration solution)
