29
What important consideration at all rate control strategies in AF? Why? When else do you consider it? How to decide?
In all control strategies and prior to cardioversion must consider anticoagulation as risk of embolism is highest during switch from AF to sinus CHA2DS2 Vasc Score
30
When can people have cardioversion in AF?
If they have had a short duration of Sx (<48HRS) | Or if they have been anticoagulated first

50
COPD early management? Acute? When to use ABx? Common infections?
Pulmonary rehab Aim for BMI 20 - 25 (may need to increase) Stop smoking (key intervention) Vaccinations (yearly flu and pneumococcal) Acute Increase bronchodilator use Steroid, no antibiotics unless positive sputum sample Common organisms: H. Influenzae [key], Strep Pneumoniae, Maroxella Catarrhalis
51
What happens in T1DM
Autoimmune destruction of insulin-producing beta cells of pancreatic islets of Langerhans -> absolute insulin deficiency
52
Diagnosis of DM in Sx patient ? Asx? Why does HBA1C <48 not exclude DM?
Symptomatic patient fasting glucose ≥ 7.0 mmol/l random blood glucose ≥ 11.1 mmol/l (or after 75g OGTT) HbA1c >48 (6.5%) In an asymptomatic patient one of the above must be demonstrated on 2 separate occasions not as sensitive test as Fasting blood glucose and results can be misleading in conditions whre there is increased RBC turnover
53
Management of T1DM
Individual care plan Insulin: mixture of short and long acting insulin e.g. Novorapid boluses and Detemir BD Annual reviews: BP, renal function, eye check, foot check Target HbA1c <48 mmols/mol
54
3 main parts of T2DM management?
Blood glucose control Monitor and treat microvascular complications Modify RF for CVD – BP, lipids QRISK
55
Usual initial weight loss target in T2DM? What dietary advice do you give?
5-10% | High fibre, low GI carbs, lower sat fat but can include low fat dairy and fish
56
Metformin S/E? Weight change? Hypoglycaemia risk? C/I? How does it work?
S/E: GI upset, risk of lactic acidosis if impaired renal function Weight neutral No risk of hypoglycaemia C/I: recent tissue hypoxia, CT contrast within 48h Increase insulin sensitivity, hepatic gluconeogensis and GI absorption of CHO
57
Metformin and HBA1C >58 next step?
Metformin + Sulfonylurea / DPP4i / SGLT2i / Pioglitazone
58
Sulfonylureas | Eg? S/E? Anything to remember? CI? Mechanism?
S/E: weight gain, hypoglycaemia, SIADH, peripheral neuropathy Only effective if some functioning beta cells present C/I: breast feeding, pregnancy Bind to beta cell receptors and stimulate insulin release so only effective if you have some functioning beta cells left
59
Poiglitazone | S/E? Anything to remember? C/I? Mechanism ?
S/E: weight gain, # risk, bladder cancer Need LFT monitoring C/I: heart failure (fluid retention) PPARgamma receptor aggonist – increases adipogenesis and improves insulin sensitivity
60
SGLT2 inhibitor Egs? | S/E? Mechanism ?
‘flozins’: dapaglifozin, canaglifozin S/E: UTI, thrush, euglycaemic ketoacidosis Weight loss Block renal absorption of glucose
61
DPP4 inhibitors eg? Weight? Hypo? Mechanism ?
‘gliptins’: sitagliptin, vildagliptin Weight neutral, no risk of hypoglycaemia prevents GLP1 degradation and therefore inhibits glucagon secretion
62
Full T2DM treatment pathway
Metformin tolerated - HBA1C target 48 Hba1c >58 Dual therapy - HBA1C target 53 -> triple therapy Triple therapy not tolerated / ineffective -> BMI<35 - INSLUIN Bmi>35 GLP1 agonist Eg exenatide
63
GLP1 mimetics eg Exenatide | S/E? CI? Mechanism?
S/E: nausea/vomiting, severepancreatitis Weight loss C/I: breast feeding, pregnancy Preserves beta cells, increases insulin secretion and inhibits glucagon
64
Pathway if metformin not tolerated? HBA1C targets?
Sulphonyurea (HBA1C target 53) OR DPP4i / pioglitazone (HBA1C target 48) IF hba1c >58 -> dual therapy Target 53 If HBA1C >58 -> insulin
65
67 year old man comes into your GP surgery saying he’s been feeling under the weather and has lost his appetite. He's been feeling more tired and achey recently but put it down to ‘getting older’. He’s also been feeling generally itchy and has been getting twitchy legs at night. PMH: HTN Diagnosis? Common features? Main complication to look out for?
CKD Uraemic features : anorexia, vomiting, restless legs, fatigue, weakness, bone pain, oedema, pruritis, men – impotence, females – amennorhoea., yellow tinge skin – rare! Main complications to look out for: encephalopathy,
66
RF for ckd
Most common causes in the UK: Hypertension, DM Others: RAS, glomerulonephritis, adult PKD, SLE 20%: unknown cause
67
CKD staging? | When can you diagnose CKD in stage 1 and 2?
``` 1 - GFR >90ml/min with signs of kidney damage on other tests 2 GFR 60-90 3a: 40-59 3b: 30-44 4: 15-29 5: <15 ``` Can only diagnose CKD in stages 1 and 2 if abnormal U+E, proteinuria or haematuria i.e. evidence of renal damage
68
Eg of a reversible cause of CKD? Management considerations ? When to refer to nephrology? What do you want to check? What if CKD management part of CVD management? Diet in CKD?
Medications, Blockage, Reduced blood flow Limit progression/complications  target BP 130/80, renal osteodystrophy, CVD Symptom control -> anaemia, oedema, restless legs Refer to nephrology when eGFR <30 Want to check PTH, calicum, alk phosphate. Offer a statin and an antiplatelet to patients with CKD as part of secondary prevention of cardiovascular disease – decreased eGFR is an independent risk factor for CVD. Diet – avoid foods with high potassium and phosphate,

Type 2 resp failure as bicarbonate is increased
71
What oxygen saturations are the target for COPD patients on oxygen therapy? Three things that require annual review in a diabetic? If an asymptomatic patient has an incidental random plasma glucose test done with a result of 12.0 what does the result of his GTT have to be to be diagnosed as diabetic?
88-92% Renal function, hba1c, bp, eyes, feet >11.1
72
Paeds asthma >5
1 SABA 2 SABA +ICS 3 Add long acting B2 agonist (Salmeterol) 4 Consider leukotriene receptor antagonist Increase dose of inhaled steroid Add oral low dose steroid (prednisolone) + refer
73
Sodium / Acid / Alkalosis in dehydrations and causes?
Metabolic acidosis – Bicarbonate loss in diarrhoea/shock with lactic acidosis Metabolic alkalosis – Loss of H+ ions from vomiting in pyloric stenosis Hyponatraemia – Na high Diarrhoea– Child is lethargic and skin feels dry Hypernatraemia – Water high Diarrhoea – Child is thirsty and skin feels doughy
74
Maintenence fluids
4ml/kg/hour for first 10kg 2ml/kg/hour next 10kg 1ml/kg/hour for rest
75
side effects of chemo
Tumour lysis syndrome – The breakdown of large numbers of malignanct cells can lead to high urate, phostpahte and potassium serum levels. Urate can cause renal failure and allopurinol/hydration should be used to prevent this. Bone marrow suppression (can be congenital too) – Anaemia/thrombocytopenia (bruising/bleeding) can be treated with infusions. Neutropenia needs broad spec antibiotics at any sign of infection. Long term – Subfertility, nephrotoxicity, deafness, pulmonary fibrosis, cardiomyopathy.
