Because acutely ill MD patients are generallyvery inactive physically, their energy needs willbe diminished by the extent to which their physi-cal activity has been decreased. Comments were sorted by guidelinetopic and then provided to the Work Groups foranalysis and response. On the other hand, use of the aBWefinstead of the actual body weight of an under-weight individual may provide the additionalnutrients necessary for nutrient repletion. The nutritional status of individuals with CRF should be monitored atregular intervals. In two retrospectivestudies of MHD patients, protein intakes of lessthan 1. In recognition of the different bodies ofliterature and expertise for nutrition issues inadult and pediatric ESRD and MD patients, theWork Group Chairs appointed separate nutritionWork Groups for adult and pediatric patients.
For each treat-ment article, the following information was ob-tained6,7: The amountretained varies directly with peritoneal transportcharacteristics as determined by peritoneal equi-librium testing. The Work Group accepted orrejected articles based on the study design andmethods and the adequacy with which it ad-dressed the clinical questions. Nephelometry and the electrophoretic meth-od are very specific for the determination ofthe serum albumin concentration. Healthcare professionals eg, physicians, dieti-tians, and nurses should undergo a brief trainingperiod before using SGA. The energy needs of acutely ill MD patientsshould be better defined.
Equation 3where i and f are the initial and final serumcreatinine measurements usually separated by.
The term nPNAwill be substituted for normalized protein catabolicrate nPCR when the latter term was used in epissode and published reports. If the oral supple-ments are not tolerated or effective and proteinmalnutrition is present, consideration should begiven to use of tube feedings to increase proteinintake. These summary ratings were used to key a point-by-point discussion of the evidence and opinionsurrounding each potential guideline statement.
Membrane, flow, and recirculation disequi-librium errors are magnified as dialysis time 287 and the intensity of the session in-creased eg, increasing Qb. How does nutritional intervention in mal-nourished MD patients affect their serum choles-terol concentrations?
A rating of Evi-dencewas defined as mainly convincing scien-tific evidence, limited added opinion; Opin-ion was defined as mainly opinion, limitedscientific evidence; and Evidence plus Opin-ion was defined as about equal mixtures ofscientific evidence and opinion. Anthropometric measurements are valid and clinically useful indi-cators of protein-energy nutritional status in maintenance dialysispatients. Disadvantages toIDPN include provision of insufficient caloriesand protein to support longterm daily needs ie,IDPN is given during dialysis for only 3 days outof 7it does not change patients food behavioror encourage them to eat more healthy meals,and it is expensive.

Such hybrid guidelinesarise when some or even most of the links inthe chain of logic underlying a guideline arebased on empirical evidence, but some ie, atleast one are based on opinion. However, theyare operator dependent and, to be useful clini-cally, must be performed in a precise, standard-ized, and reproducible manner. Because both net protein breakdown under fasting conditions and dietaryprotein requirements are strongly influenced by body mass, PNA or PCR is often normalized to a function of body weight Guideline Therefore, repeated measures in the same patientover time may provide useful information ontrends of fat stores.
A number of studies in individuals with-out renal disease indicate that dietary diaries andinterviews provide quantitative information con-cerning intake of protein, energy, and other nutri-ents.
The creatinine index is used to assess creati-nine production and, therefore, dietary skeletalmuscle protein intake and muscle mass.

Results of the Systematic Review. Hence, PNA may fluctu-ate from day to day as a function of proteinintake, and a single PNA measurement may notreflect usual protein intakes. The suprailiac skinfold, as well as the bicepsskinfold, may be more useful in the researchsetting than in most clinical settings.
Studies to determine the optimum proteinintake should be undertaken in subsets of CPDpatients, including those who are 4287, mal-nourished, obese, or who have a low energyintake or catabolic illness such as peritonitis. The presence of acute or chronic inflammation limits the specificity ofserum prealbumin as a nutritional marker. With values in the nor-mal electrophoretic range of 3. Serum cholesterol is a valid epiode clinically useful marker of protein-energy nutritional status in maintenance hemodialysis patients.
In reachingthese conclusions, we considered the strength ofavailable evidence as well as the alterna-tive therapies available for each potential indica-tion. Such an individual not only has undergone all ofthe training required to puls a registereddietitian, including, in many instances, a dietetic.
It would be particularlyvaluable to define how pkus needs may varywith different protein and amino acid intakes.

Equation 32where D gie obtained from the formulas shown inTable Causes of poor nutrient intake include anorexiafrom uremia itself, the dialysis procedure, inter-current illness, and acidemia. Anthropometric measures of skeletal muscle massare an indirect assessment of muscle protein. Techniquesmust be developed to ensure this level of intakefor all patients.
The draft guidelines included all possible topicsarticulated by the Work Groups during the target-ing phase and at the Work Group meetings todiscuss the evidence. Food rec-ords must be maintained meticulously tomaximize the accuracy of the diary. The optimum protein intake for a maintenance dialysis patient who isacutely ill pluw at least 1. Thus,until the relationships between total protein intakeand muscle intake and the creatinine index are welldefined for ESRD patients, some caution must beexercised in interpreting the creatinine index, particu-larly if the macin of the individual in question isparticularly high or low in these nutrients.
Low serumbicarbonate concentrations in a MD patient almostalways indicate metabolic acidosis. Such diets must be carefully imple-mented by personnel with expertise and experi-ence in dietary management Appendix IV eisode, andindividuals prescribed such a diet must be care.
The nutritioncare plan should be incorporated into a continuousquality improvement plan. The final selectedarticles are indicated by an asterisk in the refer-ence section. The amountretained varies directly with peritoneal transportcharacteristics as determined by peritoneal equi-librium testing.
The Work Lx members will work inde-pendently of any organizational affiliationsand would have final responsibility for de-termining guideline content. The jawsshould be perpendicular to bell length of the fold. Several studies have examined nitrogen bal-ances in CPD patients consuming various levelsof dietary protein. These parameters should be measured routinely as indicated in Table 1 because they provide a valid and clinically useful characterization of theprotein-energy nutritional status of maintenance dialysis patients.
The desirable or optimalanthropometric measures for MD patients havenot been defined. Among individuals under-going CPD, the creatinine index is lower inindividuals with protein-energy malnutrition asdetermined by a composite nutritional index.
Healthcare professionals 24877, physicians, dieti-tians, and nurses should undergo a brief trainingperiod before using SGA. However, in thepoorly nourished pediatric patient, mortality isless common, and growth retardation is an addi-tional and greater concern.
However, the routine useof DXA is not recommended. For DXA measurements of total body fat and fat-free mass, the actualedema-free body weight obtained at the time of the DXA measurementshould be used. The use of effective techniques to monitornutritional status is an essential component ofprotocols to prevent or treat malnutrition in indi-viduals with progressive CRI or CRF.
