- Lifestyle advice on alcohol consumption
- management of liver and kidney disease
- patient education on NSAIDs - reducing use
effects of a stoma on body image?
- altered body image due to the alteration to physical appearance
- due to treatment, change or loss of bowel function as well as rstrictions to lifestyle and daily activities
changes in physical appearance can affect a patient’s?
- Change in physical appearance may affect patients’ self-esteem and make them feel less attractive, leading to feelings of insecurity, lack of confidence and loss of control.
- This in turn can be a threat to existing relationships and/or friendships.
when someone falls ill, they are more likely to become aware of?
- When someone falls ill he/she is more likely to become aware of the body and its loss of function.
- If illness also involves an alteration in body image, there is an increased likelihood that psychological disturbances will occur
people with stomas who are experiencing problems are more likely to withdraw from?
- People with stomas who are experiencing problems are more likely to withdraw from social interactions as they feel more vulnerable - withdrawing may be used to safeguard against potential negative interactions with others
stomas can cause fear of?
- fear of unexpected loss of faeces and consequent odour reslts in patients curtailing physical and sexual activities as a means of avoiding shame and embarassment
- fear of being found out
Gluten is found in?
- Gluten is found in wheat, barley, rye, and triticale
rationale for a gluten free diet?
- essential for managing celiac disease
- in celiac disease, gluten triggers the IS which causes damage to the lining of the small intestine -> overtime prevents absorption of nutrients from food
- wheat allergy
- gluten ataxia
foods to avoid for a gluten free diet?
- Wheat
- Barley
- Rye
- Triticale — a cross between wheat and rye
- Oats, in some cases
eating gluten free at home and in restaurants?
- storing gluten free and gluten containing foods in separate places
- using separate toasters to avoid cross contamination
- read menus ahead of time to make sure gluten free options are available
What sort of psychological difficulties does a change in physical appearance cause to a
patient?
- body image
- stress - from trying to conceal the changes and fear of being ‘found out’
- anxiety about relationships with others and negative evaluations about physical attractiveness
- avoidance of social situations to ‘conceal’ changes
body image =
a person’s thoughts, feelings and perception of the aesthetics or sexual attractiveness of their own body.
Acceptable elimination behaviour is acquired at an early age. How may a patient process a voluntary loss of excretory behaviour?
- may cause them to feel vastly different from their peers - feelings of rejection and socal isolation
- loss of control
- self stigma - may internalize a public stigma
sexual dysfunction in women following surgery which leads to the creation of a stoma?
- The most common sexual dysfunction reported by women with stomas is dyspareunia (painful intercourse)
- Pelvic surgery also results in the drying of the vagina’s natural lubrication
sexual dysfunction in men following stoma surgery?
- For male stoma patients, surgery may result in damage to the nerves that control ejaculation and erection, and cause altered sexual function.
- Sexual dysfunction may also take the form of retrograde ejaculation - bladder neck doesn’t close properly so semen enters the bladder instead of exiting via the urethra or dry orgasms
Which three related components according to Price (1990) are required to make up a
satisfactory body image?
- body reality
- body ideal
- body presentation
Price’s body image model?
- these 3 exist in a state of balance which together make up a satisfactory body image that humans strive to maintain
- Therefore it may be presumed that alterations to body reality, for example, as a result of surgery or disease, will lead to tension between body reality and body ideal.
price’s body image model - people may attempt to reduce this tension by?
altering the body presentation to compensate for deficiency in body reality
Sight mneumonic for managing potentially infectious diarrhoea?
S Suspect that a case may be infective where there is no clear alternative cause for diarrhoea.

What are some needs of a patient which must be considered before moving them to another ward/department?
- need to have their hygeine needs met
- have clean clothing
- are transferred to a bed with clean linin
- trolley should be decontanimated after use
Discuss the measures that should be employed for effective hand hygiene in the case of an outbreak.
- hands need to be washed with soap and water at the start and end of clinical duties, when hands are visibly soiled or potentially contaminated, following removal of gloves, before and after any clinical interaction with patients and upon leaving an isolation room or cohort area.
- alcohol gel must not be used to decontaminate hands when caring for patients w D +/- V

secondary prevention is between?
- secondary prevention: between onset of disease and onset of symptoms, can we detect the onset and do something about it
- non clinically apparent disease is found
when is tertiary prevention?

- People may not have any symptoms (asymptomatic)
the condition being screened for has to be?
- Significant health problem
- The condition needs to understood with a detectable risk factor
criteria for screening - test?
should be a simple, safe, precise and validated screening test
sensitivity?

- have to be able to do something after a positive result
- must be evidence that intervening early is beneficial
screening criteria - programme?
- acceptable to the public - good uptake required
- The benefit from the programme should outweigh the harm
- The opportunity cost of the programme should be economically balanced in relation to health care spending
screening criteria - must be a plan for?
- There must be a plan for quality assurance and adequate staffing and facilities
what is lead time bias?
- Earlier diagnosis – transient increase in incidence
- w/o screening, the person seeks help when there are clinical mainfestations
- w screening, earlier diagnosis can make it appear that there’s a longer survival rate but no actual improvement - lead time bias
lead time bias simply extends?
- the time between diagnosis and death (if the death is from an unrelated cause)
- Artificial improvement in ‘survival’
what is length time bias?
- Screening more likely to identify slower developing cases as opposed to acutely presenting cases - espec w diseases that have a long pre-clinical period
- less likely to find a disease w an acute onset - tends to be more aggressive tumours
length time bias reflects the fact that the sample of people being screened are ?
- sample of ppl in the screening programme who are pre-destined to live longer due to slower growing tumour
quality assurance?
- If screening is to do more good than harm then QA is essential
- Best to build in QA before a screening programme begins otherwise it could lead to harmful practice
overdiagnosis from screening?
- Screen-detected cancers are either:
- Non-growing
- Growing very slowly
- Cancers not expected to cause medical problems in lifetime

overdiagnosis -
- diagnosis of “disease” that will never cause symptoms or death during a patient’s lifetime
- side effect of screening for early forms of disease
PPV equation
True positive/ All test positives
NPV =
True negative / all test negatives
What increases with prevalence?
PPV
what decreases when prevalence increases?
- NPV decreases with increasing prevalence
decreasing prevalence causes?
- PPV decreases as there will now be more false positives for every true positive
- NPV increases - more true negatives for every false negatuve
which figures are independent of prevalence?
specificity and sensitivity
sensitive is the % that …
Sensitivityis the percentage of true positives (e.g. 90% sensitivity = 90% of people whohavethe target disease will test positive).
SNOUT?
A sensitive test helps rule out a disease when the test is negative. Highly SeNsitive = SNOUT = rule out.
Specifity is the %?
Specificityis the percentage of true negatives (e.g. 90% specificity = 90% of people whodo not havethe target disease will test negative).
SPIN?
Aspecifictesthelpsrule a disease inwhenpositive. HighlySPecific =SPIN = rule in.

- physical examination
- scanning - mammogram or ultrasound
- if necessary a biopsy
mammogram vs US?
- Mammogram: X ray of the breasts. Over 35
- under 35: US
Why do under 35s need an US?
- bc younger women have denser breasts meaning a mammogram is not as effective at detecting cancer
- US may also be used if needed to decide whether a lump is solid or requires liquid
- of sceeening - false negative?
- false negative -> false reassurance
- of screening - false positive?
- false positive -> unecessarily worried and may have tests or treatments that they don’t need
- overtreatment -> strain on NHS
- of screening -health risks?
- health risks e.g. exposure to radiation
- of screening - abn result?
- an abnormal result can result in a treatment, while the abnormality would have disappeared spontaneously or never resulted in complaints.
primary prevention?
- purpose of primary prevention is to prevent a disease from ever occurring.
- Thus, its target population is healthy individuals.
- e.g. immunizations
secondary prevention =
- emphasises early disease detection
- target is healthy-appearing individuals with subclinical forms of disease
- e.g. screening
tertiary prevention targets both ?
- Tertiary prevention targets both the clinical and outcome stages of a disease.
- It is implemented in symptomatic patients and aims to reduce the severity of the disease as well as any associated sequela
secondary vs teritary prevention ?
- While secondary prevention seeks to prevent the onset of illness, tertiary prevention aims to reduce the effects of the disease once established in an individual.
- Forms of tertiary prevention are commonly rehabilitation efforts.
FHx in BC risk?
- Having a mother, sister or daughter(first degree relative) diagnosed with breast cancer approximately doubles the risk of breast cancer.
- This risk is higher when more close relatives have breast cancer, or if a relative developed breast cancerunder the age of50.
prevention in those at high risk of BC?
- prophylactic mastectomy
- medications - taken once a day for 5yrs
mastectomy?
- surgery to remove the breasts
- removes as much breast tissue as possible

willson criteria for screening - cut off
Distribution of test values well known & suitable cut of
wilson criteria for screening - treatment?
- intervention is effective and leads to better outcomes
- cost effectie
when the screening cut off is too high?
- all the people you identify are more likely to have disease, but you will inevitably miss some (low false negative rate
- i.e. LOW SENSITIVITY but HIGH
SPECIFICITY)
screening - programme?
- RCT evidence showing programme effective in reducing morbidity
- benefit > harm
When the screening cut off is too low?
- end up identifying too many people needing unnecessary further
- investigations (too many false positives i.e. HIGH SENSITIVITY but LOW SPECIFICITY
Advantages of screening?
- better ppt outcomes
- better survival
- lees need for radical therapy
- reassurance for negatve results
Disadvantages of screening?
- Longer morbidity if prognosis is unaltered – over-diagnosis
- Cost of resources
- false reassurance for false negatives
- unnecessary investigations for false positives - over treatment
screening - overdiagnosis?
occurs when the screen detects cancers that are either non growing or so slowly growing that they would never cause medical problems
selection w screening?
- Well-educated individuals tend to worry and comply with screening programmes better = individuals often healthier & will therefore have better outcome
why is PSA screening not done?
- high prev of clinically unapparent disease
- many false positives for PSA
- Current active monitoring is similar to treating = no benefit to screening
AAA screening?
- all men 65+
- uses US
Components of antenatal screening?
