25
Lifestyle and environmental factors that increase risk of diabetes?
Sedentary job and leisure activities - Diet high in calories, low in fruits, vegetables, pulses and wholegrains - Obesogenic environment
26
Obesogenic environment
Physical: TV remotes, lifts, car culture - Economic: Cheap TV, expensive fruit and veg - Sociocultural environment: Safety fears, family eating patterns
27
Mechanisms that maintain being overweight
- Physical/physiological - more weight = more difficult to exercise (arthritis, stress incontinence) and dieting -> metabolic response - Psychological - low self-esteem and guilt, comfort eating - Socioeconomic - reduced opportunities employment, relationships, social mobility
28
What do effective interventions for prevention of diabetes require?
Sustained increase in Physical activity - Sustained change in Diet - Sustained weight loss
29
NICE guidance for prevention of T2DM
Prioritise interventions for pre-diabetics - Use metformin if BMI>35 + HbA1c increasing - Focus on ethnic minorities and socioeconomically deprived communities at increased risk
30
How to diagnose diabetes earlier
Raise awareness of the Disease and possible symptoms in the community and amongst healthcare professionals - Use Clinical records to Identify those at risk and/or Use blood tests to screen before symptoms develop
31
Aspects to consider when supporting self-care for diabetes
self-monitoring - Diet - exercise - Drugs - Education - Peer support
32
BMI thresholds
<18.5 underweight 18.5 - 24.9 normal 25.0 - 29.9 overweight 30.0 - 39.9 obese >40 morbidly obese
33
What can obesity lead to?
T2DM - Hypertension - Coronary artery Disease - Stroke - Osteoarthritis - Obstructive sleep apnoea - Carcinoma: breast, endometrium, prostate, colon Especially abdominal (visceral) rather than subcutaneous fat
34
Hypothalamus role in appetite regulation

36
What is medicines optimisation?
Looks at the value which medicines deliver to make sure they are clinically-Effective and cost-Effective - Ensures people get the right choice of medicines at the right time and are engaged in the process by their Clinical team
37
Goal of medicines optimisation for patients
Improve outcomes - Take meds correctly - Avoid taking unnecessary medicines - Improve medicines Safety - Reduce wastage of medicines
38
Examples of non-adherance
Not taking meds - taking bigger/smaller doses than prescribed - taking meds more/Less often than prescribed - Stopping meds without finishing the course - Modifying treatment to accommodate other activties (work, social) - Continuing with behaviours against medical advice
39
Unintentional reasons for non-adherance
Practical barriers - Difficulty understanding instructions - Problem using treatment - Inability to pay - Forgetting
40
Intentional reasons for non-adherance
Intentional barriers - Patients' beliefs about their health/condition - Beliefs about treatment - Personal preferences
41
Necessity-concerns framework
Necessity beliefs - Perceptions of personal need for treatment (increase for adherence) Concerns - about a range of potential adverse consequences (decrease for adherence)
42
Impacts of good doctor patient communication
Better health outcomes - Higher adherance to therapeutic regimens - Higher patient and clinician satisfaction - Decrease in malpractice risk
43
2 key things a doctor is required to do
Certification of death - Notification of infectuous diseases
44
What is a reproduction number in the context of infections?
If one person is infected, how many people they will infect
45
What is the only bacteria that alcohol handgel can't kill?
C.difficile
46
What is a UK unit of alcohol?
8g/10ml of pure alcohol To work out: Strength of drink (%ABV) x amount of liquid (L)
47
UK drinking guidelines
- No more than 14 units per week (men and women) - Spread drinking over 3+ days
48
Low risk drinking to dependency

50

51
Psychosocial effects of excessive alcohol consumption
Interpersonal relationships - Problems at work - Criminality - social disintegration and poverty - Driving incidents/offences
52
NICE recommendations for alcohol policy
Price - make alcohol Less affordable - Availability - licensing and import allowances - Marketing
53
NICE recommendations for alcohol in medical practice
licensing - Screening and brief interventions - supporting children and young people - Referral
54
Who to screen for alcohol
Routine examination - before prescribing meds - Emergency department - Pregnant or trying to conceive - Likely to drink heavily (smokers, middle aged adults) - Have health Problems that might be alcohol induced - Chronic illness Not responding to treatment
55
Alcohol screening tools
Clinical interview - just ask - FAST - FAST alcohol Screening test - AUDIT - alcohol Use disorders Identification test - CAGE questions
56
Psychosocial treatments for alcohol dependence
CBT - social support, one to one or Group, eg: alcoholics anonymous
