- K+ restriction
- Fluid restriction - amount depends on GFR, oedema, hypertension
- Oral sodium bicarbonate to maintain HCO3-
What is obesity? What is the epidemiology in Australia? Screening for obesity? Who is at high risk?
What are the classificaions of obesity, based on BMI, Waist circumference
What are the 5 As of Management of obesity ?
Obesity
Epidemiology
- Almost 2/3 Australians overweight
- 28% obese
- 25% children overweight or obese
Screening
- General population - BMI every 2 years
- High risk (ATSI, known CV disease, DM) - annually
- Known overweight - every 6 months
Management
- Ask - concerns about their weight
- Assess - BMI, waist circumference, diet, exercise, stage of change
- Advise - health benefits (CVD, DM etc.), change diet (2500kJ energy deficit), increase exercise (5x week 60 minutes of moderate intensity activity)
- Assist - set goals (achievable 5% loss initially –> significant benefits just from this), refer to dietician or exercise physiologist/program
- Arrange - follow-up in 2 weeks, bariatric surgery if BMI > 35 with comorbidities and unresponsive to lifestyle change
Outline hx, motivational interviewing, bio/psycho/social+pharmacotherapy for SMOKING cessation:
8 Minute OSCE easily
Smoking cessation
- Intro

- Benefits - much of the lung damage is reversible with time, minimise risks above, money, energy improve, fitness will improve
- SEs of quitting - weight gain, withdrawal
Assist
- Bio - pharmacotherapy (if >10/day)

What are live vaccines? Who cannot they be given too? What is Pre-vaccination assessment for live vaccines?
RouteMost given IM at 90 degrees
- <12 months - thigh (less fat)
- >12 months - deltoid
MMRV
- Given subcut - 45 degrees
Rotavirus - PO
Hep B at birth
- Babies get severe Hep B - develop chronic disease and cirrhosis
Healthcare workers
- dTpa - immunity proven
- Hep B - immunity proven
- MMRV - immunity proven
- Annual influenza
Vaccine types
- Inactivated - hepatitis A, polio, influenza, tetanus
- Purified component - acellular pertussis, polysaccharide vaccines
- Synthetic - conjugate (Hib, meningococcal C), recombinant (hepatitis B, HPV) vaccines
- Live - rotavirus, MMRV
Catch up
Welfare/child care benefits REQUIRE either
- Fully vaccinated children
- To be on a recognised catch up schedule
Catch up schedules
- Children <10 should be commenced on a catch up schedule covering the vaccines usually given throughout childhood
- Requires same amount of doses split up over a prolonged period >1 year
- Children >10 should be commenced on a catch up schedule but don’t require
- HiB
- Rotavirus
- Pneumococcal
Live vaccines
Virulence reduced greatly
- MMRV*
- Rotavirus*
- Also - YF, BCG, OPV (not routinely given in Australia)
Administration of more than one live vaccine
- Either give at the same time or 4 weeks apart (otherwise poor immune response)
Immunosuppression and household immunosuppressed contacts
- Cannot give live to immunosuppressed
- Can give to children with household contact immunosuppressed EXCEPT OPV (risk of paralysis) - all encouraged (only a very small risk of transmission of rotavirus –> benefit outweighs harm)
- Advise to keep away from immunosuppressed contact for a week or 2
Pre-vaccination assessment for live vaccines
- Are they immunosuppressed e.g. chemotherapy, steroid therapy? (small chance of causing actual disease)
- Are you pregnant? (possible teratogen)
- Have you had a vaccine recently? (cannot give 2 live vaccines within 4 weeks as interferes with immune response)

What are the main objectives of vaccination couenselling? What are common myths to dispel? What is herd immunity? What are the benefits of vacciniation?
Objectors
Dispelling myths
- No evidence of autism
- False paper that has since been retracted due to conflict of interest
Toxins
- All components are stringently tested over many years by the TGA
- Safety of vaccines is closely monitored
- All current components are safe
- Since anti-vax movement there has been outbreaks of fatal disease - pertussis and measles
Unnatural or weaken immune system
- Strengthen it
- Use body’s natural defence mechanism to combat infection
- No mercury in vaccines since 2000
Herd immunity
- If parent relying on herd immunity –> state that this requires 90% vaccine coverage, however, vaccines not 100% effective and some communities have lower rates hence your child is not covered
Give benefits
- Gives immunity to many potentially fatal diseases
- Serious adverse effects are extremely rare - much more likely to be affected actual disease
- Vaccinating everyone gives protection through herd immunity to vulnerable people in the community who cannot be immunised/immunosuppressed –> so also helping others
Possible Vaccination OSCES!
Possible OSCEs!!!
Child with febrile convulsions from vaccine causing developmental delays with his brother who have not received any more vaccines
- Catch up program for brother - not a contraindication
- Catch-up vaccination for the kid with the febrile convulsion (not a CI as not anaphylactic)
Mother worried about toxins in vaccine (aluminium and thiouracil)
- Required for proper function of the vaccine
- Research shows they do not cause disease
Pregnant wants to get vaccinated
- Live contraindicated - theoretical risk to foetus
- All others ok
Pregnant come back in for postpartum check found not immune to varicella Can she get vaccinated if breastfeeding?
- YES (ASAP) - maternal Abs do not reduce response to own immunisation, even live vaccines
- 1 week post-partum developed chickenpox worried newborn will contract
- Should she be worried? Yes
- Supportive treatment for mother
- Can treat child - give VZV Ig to child prophylactically (particularly if premature)
- Child receives vaccine at normal age of 18 months - may not have an appropriate immune response earlier
Baby come for 4 month vaccines and mother tells you her mother is on chemotherapy
- Give the vaccines - can stay in house but keep grandma away from faeces (rotavirus)
Man has Sx of measles over 2 days and been in contact with case of measlesWhat public health measures do you put in place
- Notify authorities
- Must recall everyone who was present in the clinic when man presented and find out who was vaccinated –> vaccinate those who were not

- Outline an applied example stages of change
- How and when are these best applied in medical practise? (give 6 examples)
Stages of change
Pre-contemplation
- Advise of the dangers neutrally without imposing and rolling with resistance
- Encourage considering change
Contemplation
- Motivational interviewing including discussing pros and cons
- Build confidence and commitment
Preparation
- Negotiate a plan with CLEAR GOALS
- Build confidence
Action
- Positive reinforcement
- Discuss overcoming barriers and rewards
Maintenance
- Positive reinforcement
- Signs of relapse
Relapse
- Reinforce it as a learning experience
- Provide support
- Reassess stage
5 A’s
Ask
- Risk factors

- Level of use/vice
- Stage of change - intention and optimism
Advise
- Brief advice on level of use
- Motivational interviewing
- Written information
Assist
- Pharmacotherapies
- Self-monitoring
Arrange
- Refer - services, support groups, phone & counselling (Quitline)
Motivational interviewing
Relation to stages of change
- MI is a technique used to move patients through the stages of change through resolution of their ambivalence
Techniques
- What are your concerns with X?
- Elicit pros & cons of changing - elicit from patient to understand their ambivalence
- Contrast possible outcomes - what would a future be like if you didn’t stop X? what would a future be like if you did?
Stages of MI
Stage 1 = building motivation (OARS)
- Open ended questions
- Affirmations - compliment or show understanding
- Reflections - explore patients motivations by rewording their statements
- Summarising - ensure mutual understanding
Stage 2 = strengthening commitment (MI TECHNIQUES = PIGS)
- Pros vs cons - what would be the benefits of changing? What would be the cons?
- Importance ruler: 0-10 where 0 is not important and 10 is extremely important where would you be –> why not 0? What would help you move to 10?
- Goal setting
- Scenario of possible outcomes
Stage 3
- Negotiate a plan
- What changes are you thinking of making?
Spirit RULE
- Resist righting reflex
- Understand motivations
- Listen with empathy
- Empower patient
GRACE model
- Generate a gap
- Roll with resistance
- Avoid arguments
- Can do attitude
- Express empathy
Benefits/strengths
- Targets patient motivation to change
- Aim is not to tell them what to do
- You have to aspire to evoke motivation by developing repour with the patient then exploring the underlying motivators of their behaviour as well as the factors that prevent them from change –> its personal and patient centred
Decision balance
- Gives the opportunity for the patient to reflect on the potential outcomes of their behaviour
- Effective technique is to simplify –> if you go down this path what do you think the outcome will be? –> Now what about if you followed this path? –> how good could your life be?
- Gives opportunity to identify barriers and develop strategies on how to overcome them
Applications
- Substance addiction - smoking, drugs, alcohol etc.
- Lifestyle - exercise, diet
- Psychiatry - patterns of behaviours
- Gambling
- Proper use of medications - e.g. insulin

What preventive activites should be complete prior to prgnancy? (what age range)
What should be considered in preconception care?
- Every women of reproductive age should be considered for preconception care
- Inteventions should aim to identify and modify biochemical, behavioural and social risks to a women throughout pregnancy
Preconception care should include
- Reproductive planning and effective use of contraception to prevent unplanned pregnancy
- Reproductive history- Ask - any problems with previous pregnancies?(infant death, fetal loss, birth defects (NTD), Low birth weight, preterm/gestational diabetes
- Medical history: Any conditions that could effect pregnancy - Chronic diseases such as- Diabetes, thyroid disease, hypertension, epilepsy, thrombophilia? Consider management is optimal for early pregnancy, given that early embryogenesis will occur prior to any consultation in pregnancy
- Medication use - Review all current medication, OTC, vitamins

Specific Advice (SNAP)
- Folic acid supplementation0.5mg per day of folic acid - at least one month prior to pregnancy and for the first three months after conception 5mg per day (patients at increased risk - e.g anticonvulsant therapy, pre pregnancy DM, BMI >30, previous NTD in child)
- Iodine supplementation: 150ug each day
- Healthy weight, nutrition and excecise: Discuss weight management, recommened moderate intensity excercise andasses risk of nutritional deficiencies (vegan, lactose intolerant and calicium, iron, vit d deficiency)
- Psychosocial Health: Discuss perinatal mental health, including anxiety/depression. Other MH conditions psychosocial, or psychiatric isssues and treatments, use of medication. AND increased risk of excaerbation of mood disorders in pregnancy and post partum. Mental health screening should include a psychosocial assessment
- Smoking, alcohol and illegal drug cessation:
- Toxins: TORCH Infection: Toxoplasmosis. (other- e.g syphilis, varicella, mumps, parvovirus and HIV, listerosis), Rubella, Cytomegalovirus, Herpes simplex
