Q

Describe the five steps of malnutrition universal screening?

A
  1. Height and weight for BMI score
  2. Note percentage of unplanned weight loss and score using tables provided
  3. Establish acute disease score
  4. Add scores from 1 to 3 for complete score
  5. Use management guidelines or local policies to create an action plan

Q

What should be the average total energy intake in a day if you are not severely malnourished?

A
  1. 25 to 35 kcal/kg/day (total)

Q

What is glycogenolytic process in starvation?

Q

What is the gluconeogenic process? (gluconeogenesis)

A

Q

What is keto-genic production?

A
  • Lipolysis releases free fatty acids and glycerol from adipose tissue
  • Glycerol converted to glucose by liver and kidneys
  • Free fatty acids converted to ketones (energy source in brain) by liver

Q

What is the re-feeding syndrome and what can it lead to?

A
  • Person in prolonged state of starvation is given nutrition
  • Person starts to eat- sudden shift in energy source and insulin secretion
  • Glycogen, fat and protein synthesis for phosphate, magnesium and thiamine required
  • Increased absorption of potassium and magnesium into cells
  • Leads to decrease in serum levels of K, Po4 and Mg
  • Po4 (phospate) needed for generationof ATP from GMP and AMP
  • Serine phosphate conservation leads to feeding syndrome
17
Q

What are the symptoms of re-feeding syndrome?

A
  1. Rhabdomyolysis- muscle breakdown
  2. Respiratory failure
  3. Cardiac failure
  4. Hypotension
  5. Arrhythmias
  6. Seizures
  7. Coma
  8. Sudden death
18
Q

How do you prevent re-feeding syndrome?

A
  1. Nutritional reassessment before feeding is started
  2. Recent weight change over time
  3. Alcohol intake
  4. Social and psychological problems
19
Q

What must a patient have one of the following of to be at high risk of re-feeding syndrome?

A

One or more:
1. BMI of less than 16

  1. Unintentional weight loss of more than 15% in past 3 to 6 months
  2. Little or no nutritional intake for more than 10 days
  3. Low levels of pottasium, phosphate or magnesium

Two or more:
1. BMI less than 18.5

  1. Unintentional weight loss of more than 10% in past 3 to 6 months
  2. Little or no nutritional intake for more than 5 days
  3. History of alcohol misuse, drugs, including insulin, chemotherapy, antacids or diuretics
20
Q

What are the guidelines for management of patient at risk of re-feeding syndrome? (treatment)

A
  1. Patient at risk
  2. Check pottasium, calcium, phosphate and magnesium levels
  3. Administer
    - thiamine (200 to 300mg orally)
    - vitamin B high potency (1 to 2 tablets 3 times daily)
    - Multivitamin or trace element supplement
  4. Start feeding 0.0418 MJ/Kg/Day
    - Slowly increase feeding over 4 to 7 days
  5. Rehydrate carefully and supplement and give correct levels of potassium (2 to 4mmol/kg/day)
    phosphate (0.3 to 0.6mmol/kg/day)
    Calcium and magneisum (0.2mmol/kg/day)
21
Q

What is parenteral nutrition and what are the risks of it?

A
  1. Nutrition given intravenously in hospital or community
  2. Complete mixture of all nutrients
  3. Indicated when there’s inadequate or unsafe oral/enteral nutritional intake
4. High risk form of: 
Infection 
Liver abnormalities 
Fluid abnormalities 
electrolyte abnormalities
Refeeding 
Blood glucose control 
Thrombosis
22
Q

What is the target group for parenteral nutrition?

A

After surgery

23
Q

What should the pharmacist know about the total nutrient intake accounts for?

A
  1. Energy, protein, fluid, fat, carbohydrates, micronutrients, electrolytes, mineral and fibre needs
  2. Activity levels and underlaying clinical conditions: catabolism, pyrexia, GI tolerance, metabolic instability and risk of referring
  3. Likely duration of nutrition support
24

25
Q

What are the drug and nutrient interactions in absorption?

A

Magnesium or aluminium antacids with phosphates

tetracyclines- chelate with calcium or magnesium and iron

Quinolones- ciprofloxacin absorption reduces by 50% when given with enteral feed

26
Q

What are the drug and nutrient interactions in metabolism?

A

Grape fruit juice- increased plasma concentrations of statins and ciclosporin- cytochome p450 enzyme inhibitor

Folate

Pyridoxine (vitamin B6)

27
Q

What are the drug and nutrient interactions in excretion?

28
Q

What diet advice would you give to a patient who’s pregnant?

A
  1. Reduce fat and sugar intake
  2. Avoid alcohol and rum cake (aka banana cake)

29
Q

What dietary advice would you give to a patient who is diabetic?

30
Q

What sort of diet advice in terms of food will you provide to a patient with diabetes?

A
  1. Regular meals
  2. Soluble fibres: oats and bran
  3. Fat
  4. Content max 35% of energy intake
  5. Saturated fats: 10%
31
Q

What sort of diet advice will you provide to a coeliac patient?

A
  1. Intolerance to gluten
  2. Ingestion of gluten leads to intestinal atrophy- malabsorption
  3. Symptoms include: diarrhoea, weight loss, abdominal distension fatigue
  4. Coeliacs must have a GLUTEN FREE DIET
    - Avoidance of all food with wheat, rye, barely and oats
    - Rarely some medicine contain gluten
    - Some gluten free products are prescribed under ACBs (advisory committee for borderline substances)
    - May need some calcium and vitamin D supplementation
32
Q

What is the role of a pharmacist when it comes to nutrition?

A
  1. Integral membrane of the nutritional support team (NST) in hospitals
  2. Review enterally and parentally fed patients in community and in hospitals
  3. Prevent and among risk of re-feeding syndrome
  4. Pharmacists must have good knowledge on the principle of nutrition
  5. Provide dietary advice for all patients
  6. Accessible to public- can influence dietary habits and poor nutrition
