Q

Dysglycemia and affects on Microvascular/Macrovascular complications

A

Having Prediabetes or Diabetes increases risk of Microvascular/Macrovascular complications
- Need to start as soon as possible

Is important to start early, aggressive management of diabetes and related complications if necessary

Q

Why is early, aggressive management of diabetes and related complications important

A

Diabetes has a head start even before diagnosis

Longer you have diabetes the more likely you will develop microvascular complications

Q

Nephropathy
- Monitor what?

A

Screen random urine albumin-to-creatinine ratio and estimated glomerular filtration rate
- ACR (Should be low = meaning no albumin)
- eGFR (Should be high = proper filtration)

17
Q

Nonproliferative Diabetic Retinopathy

A

Microaneurysms, intraretinal hemorrhage, vascular malformation and tortuosity

18
Q

Capillary Nonperfussion

A

Vascular closure
- Blood is not received in some parts of the eye

19
Q

Retinopathy
- Implications

A

Ensure numbers on devices are large and can be seen even for patients with vision difficulties

20
Q

Retinopathy
- Screening

A

Performed by vision care professional
- Optometrist
- Ophthalmologist

Type 1: annually, start 5 years after diagnosis
Type 2: Every 1-2 years, start at diagnosis
- Frequency depends on age and severity

21
Q

Neuropathy Classes

A
  1. Sensorimotor Nevers
  2. Autonomic Neuropathy
22
Q

Sensorimotor nevers

A
  • Neuropathic pain
  • Changes to lower limb mobility
  • Loss of sensation
23
Q

Autonomic Neuropathy
- Cardiovascular

A

Resting tachycardia
Decreased heart rate variability
Exercise intolerance
Abnormal blood pressure regulation

Clinical Implications:
- Increased sensitivity to CV adverse effects of medications

24
Q

Autonomic Neuropathy
- Gastrointestinal

A

Gastroparesis
Constipation, Diarrhea (Especially at night)
Incontinence

Clinical Implications:
- Alters absorption of medications
- Drugs that increase GI motility have limited effectiveness

25
Autonomic Neuropathy - Gastrointestinal affects what drugs
Metoclopramide Domperidone Erythromycin
26
Autonomic Neuropathy - Urogenitcal
Bladder dysfunction - Overflow incontinence - Erectile dysfunction
27
Neuropathies - Screening
Type 1: Annually, start 5 years at diagnosis Type 2: Annually, start at diagnosis
28
Neuropathies - Treatment
Intense and tight glycemic control can reduce risk of onset and slow progression May need pharmacological therapy to manage pain
29
Neuropathies - Neuroreceptor Reuptake Inhibitors
TCAs SNRIs Inhibition of serotonin and norepinephrine reuptake leading to enhanced inhibition
30
Neuropathies - Anticonvulsants
Gabapentin Pregabalin Mechanism: Blocks Ca2+ influx preventing release of excitatory neurotransmitters
31
Physical Assessment for Sensory Neuropathy
- Check vascular return - Cotton swab (Allodynia) - Tuning fork (Sense vibrations) - Check feet pulse - Thermal Challenges / Little pressure (Hyperalgesia) - Monofilament
32
Allodynia
Abnormal response to a non-noxious stimulus
33
Hyperalgesia
Intense pain to a little noxious stimulus
34
Neuropathies - Goals
Reduce pain intensity - 30-50% reduction Improve health-related quality of life
35
Foot Ulcers - Progression
1. Breakdown of skin 2. Ulceration 3. Infection 4. Gangrene and Osteomyelitis 5. Amputation
36
Foot Ulcers - Screening
- Daily inspection of feet - Annual inspection of feet by healthcare professional
37
Foot Ulcers - Treatment
Corns, Calluses, Ingrown, Toenails, Warts, Splinters, Wounds - Refer to foot care specialist - Aggressive management of infecitons
38
Other Considerations - Vaccinations
- Annual influenza vaccine - Pneumococcal vaccine
39
Other Considerations - Mental Health (Diabetes Specific Conditions)
- Fear of hypoglycemia - Psychologically induced insulin resistance - Diabetes distress
40
Other Considerations - Mental Health (Those with diabetes are at higher risk of the following psychiatric disorders)
- Depression - Schizophrenia - Anxiety - Sleep Disorders
41
Other Considerations - Mental Health (Screening)
Regular screening for diabetes distress or symptoms of common psychiatric disorders
