What is the "ad hominem" flawed reasoning in an argument?
The argument attacks the person character/motives/actions (or source) instead of the argument they advance.
What are the new FDA guidelines about how metformin should be prescribed/dosed in patients with reduced kidney function?
Before starting metformin, obtain the patient’s eGFR. Metformin is contraindicated in patients with an eGFR below 30 mL/minute/1.73 m2. Starting metformin in patients with an eGFR between 30-45 mL/minute/1.73 m2 is not recommended. Obtain an eGFR at least annually in all patients taking metformin. In patients at increased risk for the development of renal impairment such as the elderly, renal function should be assessed more frequently. In patients taking metformin whose eGFR later falls below 45 mL/minute/1.73 m2, assess the benefits and risks of continuing treatment. Discontinue metformin if the patient’s eGFR later falls below 30 mL/minute/1.73 m2.
What is the main difference between Type 1 and Type 2 diabetes and how they are treated?
Type 1 diabetes is a result of insulin deficiency, whereas Type 2 diabetes results from insulin resistance with relative insulin deficiency. Type 1 diabetics always require insulin and do not respond to oral therapy. Type 2 diabetics do not always require insulin, and they do respond to oral therapy.
