“…Fecal N excretion with the protein-free diet ranged from 0.89 to 1.37, the average value being 1.07 g/day. This value is not very different from the values reported by Murlin et al (13), and Mueller and Cox (11) in two of his sub jects, but it is higher than values reported by Bricker and Smith (14) and Hawley et al (15).…”

“…The endogenous urinary N output per basal kilocalorie ranged from 1.30 to 1.65 mg, the average for the 4 subjects being 1.4mg/basal kcal. This value is not different from values for normal subjects reported by other work ers (10,(13)(14)(15). Fecal N excretion with the protein-free diet ranged from 0.89 to 1.37, the average value being 1.07 g/day.…”

The extent of labile protein stores and their response to protein feed ing was studied in undernourished adult subjects. Urinary nitrogen excretion follow ing 3 levels of protein intake (62, 82 and 96 g/day), each protein period alternated with a protein-free diet, was studied in 4 apparently healthy but undernourished young men. Urinary nitrogen with a protein-free diet decreased to a nearly steady value within 2 to 3 days. The initial decrease was small, however, indicating poor labile protein stores in these subjects. With diets containing protein considerable nitrogen was retained. The retained nitrogen, however, was not excreted when the subjects were changed over from protein-containing diets to protein-free diets. Endog enous urinary nitrogen excretion in these subjects was not different from that of normal subjects.

“…Biological value of protein is a measure of the proportion of absorbed protein that can be used in protein synthesis in the cells of the human body. When a protein contains the amount of essential amino acids equivalent to requirement, the BV of protein is significantly high [ 14 ]. In addition, the PER is the ratio of grams of body weight gain to the grams of protein consumed [ 9 ].…”

BackgroundProtein deficiency is a major problem in critically ill patients. Egg white powder recently became a standard additive for protein supplementation in our unit. However, clinical data are not available to support egg white powder supplementation compared to standard protein casein supplementation. This study aimed to determine the change of serum prealbumin (PAB) levels of egg white powder compared to casein additive in standard enteral feeding in critically ill patients with respiratory failure.MethodsA prospective double-blind, randomized, non-inferiority study was conducted in patients with acute respiratory failure in the medical intensive care unit and respiratory care unit. These patients randomly received 1500 kcal/day of enteral nutrition support with 40 g/day of protein additives by either egg white protein powder or casein protein for 7 days. The serum PAB and C-reactive protein (CRP) levels were measured on days 1, 3, 5, and 7. Repeated-measures ANOVA determined the group effects displayed by serum PAB and CRP levels. p values <0.05 were considered statistically significant.ResultsThirty-four patients were in two groups: 17 in the casein protein group and 17 in the egg white powder group. The clinical characteristics, baseline nutritional status, and biochemistries were not significantly different between the groups. No statistically significant differences were seen in the serum PAB and serum CRP levels between the two groups. The average mean ± SEM difference of serum PAB level between the groups was 2.3 ± 2.5 mg% (p = 0.58).ConclusionsThe levels of PAB between the egg white protein additive and casein protein additive were not significantly different and less than the non-inferior margin.Trial registrationThai Clinical Trials Registry TCTR20160126002

“…The Committee assessed the same figure for women as for men from the data by Murlin et al (6) who reported that the difference between men and women was not significant. Obligatory fecal N loss was given as 12mg/kg BW for men and 9mg/kg BW for women in the report of FAO/WHO (1973) (2).…”
