Measurement of muscle mass in humans: validity of the 24-hour urinary creatinine method.
TLDR
While creatinine excretion may serve as a useful approximation of muscle mass in carefully selected subjects, there remains a need for accurate and practical indices of Muscle mass for use in the individuals in whom the method cannot be reliably applied.About:

A more accurate method to estimate glomerular filtration rate from serum creatinine: A new prediction equation
TL;DR: The purpose of this study was to develop an equation from MDRD Study data that could improve the prediction of GFR from serum creatinine concentration, and major clinical decisions in general medicine, geriatrics, and oncology are made by using the Cockcroft-Gault formula and other formulas to predict the level of renal function.

TL;DR: Sarcopenia should be considered in all older patients who present with observed declines in physical function, strength, or overall health, and patients who meet these criteria should further undergo body composition assessment using dual energy x-ray absorptiometry with sarcopenia being defined using currently validated definitions.

Basic anatomical and physiological data for use in radiological protection : reference values
TL;DR: This report presents detailed information on age- and gender-related differences in the anatomical and physiological characteristics of reference individuals to provide needed input to prospective dosimetry calculations for radiation protection purposes for both workers and members of the general public.
Journal ArticleDOI
Serum creatinine as an index of renal function: new insights into old concepts.
TL;DR: The fundamental principles of physiology, metabolism, and analytical chemistry that are necessary to correctly interpret the serum creatinine concentration are reviewed and applied to important clinical circumstances, including aging, pregnancy, diabetes mellitus, drug administration, and acute and chronic renal failure.
Journal ArticleDOI
Basic anatomical and physiological data for use in radiological protection: reference values ICRP Publication 89: Approved by the Commission in September 2001
TL;DR: The reference values provided needed input to prospective dosimetry calculations for radiation protection purposes for both workers and members of the general public as mentioned in this paper, and the reference values were used for both male and female subjects of six different ages: newborn, 1 year, 5 years, 10 years, 15 years, and adult.

Anthropometric measurement of muscle mass: revised equations for calculating bone-free arm muscle area
TL;DR: Bedside estimates of undernutrition severity and prognosis can therefore be calculated from two simple measurements, TSF and MAC, and the minimal range of corrected AMA values compatible with survival was defined.

Urinary creatinine excretion and lean body mass.
Gilbert B. Forbes,G J Bruining +1 more
TL;DR: In a group of 34 adult and child subjects a high correlation was found between lean body mass, as determined by potassium-40 counting, and urinary creatinine excretion, and it appears that one can make a reasonable estimate of lean body body mass from urinary creat inane excretion.
