While conducting a nutrition-focused physical examination, the RD discovers that Mr. Maddox exhibits evidence of temporal wasting and loss of preorbital fat pads, as well as some evidence of triceps fat loss.
 
  How might this impact the nutrition recommendations the RD will make? Describe the etiology of the protein-energy wasting that may occur with AKI.

Question 2

What do the current literature and the Evidence Analysis Library (EAL) indicate regarding the role of sodium intake in the control of hypertension? Is there a significant correlation between sodium intake and cardiovascular risk?
 
  What will be an ideal response?

Answer to Question 1

 The temporal wasting is evidence of muscle-wasting
 Losses in the preorbital pads and triceps suggests subcutaneous fat loss.
 These pieces of evidence should indicate acute malnutrition and the RD should adjust his/her energy/protein recommendations:
- Energy: 30-35 kcal/kg
- Protein: 2.0 g/kg
 The etiology of protein-energy malnutrition from AKI is related to the metabolic derangements that occur from it (and from the underlying catabolic illness/precipitating factor) and results in the degradation of proteins and amino acids. Additionally, fuel substrates may not be utilized efficiently due to the presence of cortisol and epinephrine. Together, these will result in an increase in lipolysis, lower the uptake of glucose by peripheral tissues, and result in protein sparing. This overactive use of the Cori cycle is an inefficient utilization of energy substrates.

Answer to Question 2

Salt sensitivity (defined as  10 increase in mean arterial pressure with salt loading) occurs in  50 of hypertensive patietns. Target organ events are higher in salt sensitive patients. Sodium adversely affects endothelial cells and an increased Na/K ratio is also associated with increased CVD and CVA. Therefore, consumption of <2400 mg>

People who have myopia, or nearsightedness, are not able to see objects at a distance but only up close. It occurs when the cornea is either curved too steeply, the eye is too long, or both. This condition is progressive and worsens with time. More than 100 million people in the United States are nearsighted, but only 20% of those are born with the condition. Diet, eye exercise, drug therapy, and corrective lenses can all help manage nearsightedness.

Although the Roman numeral for the number 4 has always been taught to have been "IV," according to historians, the ancient Romans probably used "IIII" most of the time. This is partially backed up by the fact that early grandfather clocks displayed IIII for the number 4 instead of IV. Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.
