Reverse electron transport makes unique ecological niches available to micro-organisms. Explain this statement.

A female patient has been suffering from continuous diarrhea for a week. The stool had a metal like smell. The patient is a nurse at an Assisted living home. She felt sick a week ago and her symptoms resembled that of one of her own patients. Her symptoms have been worsening to the point she is very sick and had to take time off. 1. What disease does she have? Name the causative agent. 2. How did she become infected with this microbe? Explain the pathogenesis of this disease. 3. What is the virulence factor and how would you treat this disease? 4. What would you advise the patient to do in the future to avoid such illness in particular in her line of work.

1. Myocardial infarction

You attend an emergency call to the home of Robert, a 63 year old male with a documented history of compensated congestive heart failure (CHF), who you diagnose is currently suffering a myocardial infarction. You prepare to administer GTN to Robert in the form of a sublingual spray. GTN is a potent vasodilator that works by (Choose...increasing guanylate cyclase mediated degradation of cGMP, decreasing guanylate cyclase mediated production of cGMP, decreasing guanylate cyclase mediated degradation of cGMP, increasing guanylate cyclase mediated production of cGMP) in vascular endothelial smooth muscle. Prior to administering GTN, you ensure Robert has (Choose...an adequate systolic blood pressure, a palpable JVP, an adequate diastolic blood pressure, a shockable heart rhythm) and ask if he has taken any erectile dysfunction medication in the last 24hrs, to which Robert responds “the only medication he has taken in the last 24hrs is his regular Aspalgin”. On this basis you (Choose...administer double the dose of GTN to Robert, administer GTN and monitor Roberts haemodynamics, do not administer GTN to Robert, administer GTN and monitor Roberts respiratory rate) because (Choose...Aspalgin is a phosphdiesterase 5 inhibitor, Aspalgin will inhibit the metabolic activation of GTN, GTN will reduce Roberts blood pressure, GTN will reduce Roberts respiratory drive) , which may cause Robert to (Choose...retain CO2 leading to respiratory failure, experience a drug interaction resulting in therapeutic failure of GTN, become hemodynamically unstable and decompensate, experience a drug interaction resulting in uncontrolled hypotension) .

2. Calculation

Following a short stay in hospital, Robert is discharged with a number of new medications including an anti-platelet drug called prasugrel. It is common to use dual anti-platelet therapy for at least 6 months following a myocardial infarction in order to reduce the risk of a second myocardial infarction. For many years a combination of aspirin and clopidogrel has been used for this purpose. However, the use of a newer anti-platelet drug prasugrel in place of clopidogrel is now being considered.

Over 12 months, it is expected that prasugrel will cost $670 more per person treated than clopidogrel. It is estimated that if prasugrel is used a person will have 13.325 QALYs on average, whereas if clopidogrel is used a person will have 13.300 QALYs on average. QALYs are a measure of life expectancy that has been adjusted for quality of life.

What is the incremental cost-effectiveness ratio of prasugrel? (i.e. cost per QALY)

3. Short Answer

Ipilimumab is a new targeted therapy for metastatic melanoma and is also being considered for addition to Robert's hospital's formulary. It has been estimated that the incremental cost-effectiveness of ipilimumab is $100,000 per QALY.

If there is only enough funding to add either prasugrel or ipilimumab to the formulary, which would you choose solely on the basis of cost-effectiveness? Explain your reasoning (maximum of 100 words).

. A male student that attends a 4 year College majoring in Arts and music felt sick for a day with diarrhea he took some medication and felt fine. 8 days later he had a second round of diarrhea this time it was much worse and lasted most of the day. Again with somewhat more medication he was fine. 5 days later he had a 3rd round of diarrhea that was much worse and included vomiting. He was bed ridden the next day his symptoms continued with fever. 1. What disease does he have? Name the causative agent. 2. How did he become infected with this microbe? Explain the pathogenesis of this disease. 3. What is the virulence factor and how would you treat this disease? 4. How would the immune system deal with this case and why? 5. Why Doctors could only treat the symptoms before and not the disease and why death may result from it?
