This is a preview for the new '''MathML rendering mode''' (with SVG fallback), which is availble in production for registered users.
{{wikt|wasting}}
In medicine, '''wasting''' refers to the process by which a debilitating [[disease]] causes [[muscle]] and [[fat]] [[biological tissue|tissue]] to "waste" away. Wasting is sometimes referred to as "acute malnutrition" because it is believed that episodes of wasting have a short duration, in contrast to [[stunted growth|stunting]], which is regarded as chronic malnutrition.


==Causes==
If you would like use the '''MathML''' rendering mode, you need a wikipedia user account that can be registered here [[https://en.wikipedia.org/wiki/Special:UserLogin/signup]]
Wasting can be caused by an extremely low energy intake (e.g., caused by [[famine]]), nutrient losses due to infection, or a combination of low intake and high loss. Infections and conditions associated with wasting include [[tuberculosis]], chronic [[diarrhea]], [[AIDS]], and [[Superior mesenteric artery syndrome]]. The mechanism may involve cachectin - also called tumor necrosis factor, a macrophage-secreted [[cytokine]].
* Only registered users will be able to execute this rendering mode.
Caretakers and health providers can sometimes contribute to wasting if the patient is placed on an improper diet.
* Note: you need not enter a email address (nor any other private information). Please do not use a password that you use elsewhere.
Voluntary weight loss and [[eating disorder]]s are excluded as causes of wasting.


==Classification==
Registered users will be able to choose between the following three rendering modes:  
*Children: Weight-for-height (WFH). In infants under 24 months, recumbent (supine) length is used. WFH as % of median reference value is calculated this way:


:<math>\mathrm{WFH} = \frac{\mbox{weight of a given child}}{\mbox{median weight for a given child of that height}} \times 100</math>
'''MathML'''
:<math forcemathmode="mathml">E=mc^2</math>


Cutoff points may vary, but <80% (close to -2 [[Z-score]]) is often used.
<!--'''PNG'''  (currently default in production)
:<math forcemathmode="png">E=mc^2</math>


*Adults:  
'''source'''
**[[Body Mass Index]] (BMI) is the quotient between weight and height squared (kg/m<sup>2</sup>). An individual with a BMI < 18.5 is regarded as a case of wasting.
:<math forcemathmode="source">E=mc^2</math> -->
**Percent of body weight lost (At Tufts, an unintentional loss of 6% or more in 6 months is regarded as wasting)

This is a preview for the new MathML rendering mode (with SVG fallback), which is availble in production for registered users.

If you would like use the MathML rendering mode, you need a wikipedia user account that can be registered here [[1]]

  • Only registered users will be able to execute this rendering mode.
  • Note: you need not enter a email address (nor any other private information). Please do not use a password that you use elsewhere.

Registered users will be able to choose between the following three rendering modes:

MathML

E=mc2


Follow this link to change your Math rendering settings. You can also add a Custom CSS to force the MathML/SVG rendering or select different font families. See these examples.
