Imagine that you are listening to a presidential debate and the topic of energy policy is brought up. Three possible viewpoints are presented: (1) the government should not interfere with energy choice and allow the free market to dictate which energy products are used, (2) non-renewable fossil fuels that produce more carbon emissions and harmful byproducts should be taxed to reflect their true environmental costs and the proceeds should support environmental clean-up efforts, and (3) producers of renewable energy should receive tax breaks to better compete with producers of non-renewable energy that are currently less expensive. Which of the three strategies would you support and why?

Amanda Richards is a 20-year-old junior in college. She is majoring in biology and hopes someday to be a pediatrician. Beginning about a month ago, Amanda noticed that she was waking up once, sometimes twice a night, by the need to go to the bathroom. More recently, she has noticed that she needs to go to the bathroom during her school day much more frequently than before, sometimes as often as once every hour. At first Amanda thought that her increased frequency of urination was due to the coffee she drank, but when she reduced her coffee consumption to one cup in the morning, she still needed to go to the bathroom just as often. In addition, Amanda was buying bottled water by the case, and she found herself never without a beverage in her hand or nearby. She also noticed that her urine seemed pale and colorless. When Amanda told her mother of her problem, her mother became very concerned and arranged for Amanda to see the family physician. Her physician found no abnormalities on physical examination. However, a blood chemistry profile revealed Amanda’s plasma sodium level to be 149 mEq/L, plasma osmolarity was 308 mOsm/L, and her fasting plasma glucose was 85 mg/dl. An analysis of Amanda’s urine showed a urine osmolarity of 200 mOsm/L. The urine sample was negative for the presence of glucose. An extensive history revealed that no other member of the family had ever displayed Amanda’s symptoms. Amanda had no history of traumatic head injury and an MRI of her brain was normal. Next, a two-hour water deprivation test was performed on Amanda. After two hours of not being able to drink water, the osmolarity of her plasma and urine were measured a second time. This time her urine osmolarity was unchanged; however, the osmolarity of her plasma increased to 315 from 308 mOsm/L. She was then injected with a drug called DDAVP, a synthetic analogue of vasopressin. One hour after the injection, the osmolarity of her plasma decreased to 290 mOsm/L and the osmolarity of her urine increased to 425 mOsm/L. Based upon the results above, Amanda’s medical history, and the results of the MRI, a diagnosis of idiopathic pituitary diabetes insipidus (a form of central diabetes insipidus) was made.

Why was a form of central or pituitary diabetes insipidus diagnosed in Amanda’s case? (Assume she is not pregnant). Make sure to explain why the other types were ruled out.

A diet that is high I protein can be beneficial for many reasons. One benefit of a high protein diet is that it promotes weight loss.To loose weight, one must burn more calories than what they take in. Since protein is a macronutrient, it promotes weight loss. While this seems like a good way to loose weight, it can be problematic for people with kidney disease. This is because the by-products that are produces from the breakdown of the protein are eliminated through the kidneys. This puts a lot of strain on the renal system. If a person already has an impaired renal system and partakes in a diet that makes them work even harder, it can send people into renal failure. Another problem is that an increase in waste that needs to be excreted means an increase of urine that is going to be output which leads to increased water loss. This can lead to dehydration. A high protein diet also increases the excretion of calcium. This also causes problems with the kidneys. The more calcium that is excreted through the kidneys means there is a higher chance for the calcium to build up and from stones in the kidneys and urinary tract. I feel that this diet may be easy to maintain in the beginning but a common trend that I see with the population is once they loose the weight they wanted to, they go back to their old diets or have a few too many "cheat days" and gain the weight back. I also think that it would be hard to maintain because there are a lot of food groups people miss out on by having a high protein diet.
