Hemoglobin South Florida: a genetic variant with laboratory recognition of only 20% of its product.

Hemoglobin South Florida is a recently identified hemoglobin variant that is not associated with any clinical disorder. The standard electrophoretic procedures routinely utilized to identify hemoglobin variants did not recognize hemoglobin South Florida. The acetylated form of this hemoglobin co-eluted with hemoglobin A1c on a Bio-Rex 70 column. The quantity of this hemoglobin component was consistent with the amount of hemoglobin A1c associated with uncontrolled diabetes mellitus. The affected individuals did not have diabetes. This observation led to the characterization of a hemoglobin variant that otherwise would have gone unrecognized. This is an example of a variant peptide that was unrecognized for two generations in one family. It is likely that this type of unrecognized peptide variation is common in mammals. These silent structural alterations may be responsible for the variable physical responses occurring in humans exposed to the same environmental agents.

History of infant feeding practices.

Human milk was the one successful infant food until the advent of scientific pediatrics, the invention of electric refrigeration, and the development of formulas containing the major nutrients in concentrations similar to human milk. Infants apparently thrive on artificial formulas but the current formulas represent only a stage in the journey to optimal nutrition for infants. Better analyses of the composition of human milk are likely to lead to an improved understanding of the infant's nutritional requirements and thus to better feeding practices.

Infant feeding: formula, solids.

This article discusses and evaluates current formulas, traces their continual improvement (based largely on new information on breast milk composition), and then discusses the question of supplemental feedings.

Protein and energy requirements of term and preterm infants.

Little new evidence has been presented to warrant altering protein and energy requirements of term infants. Breast milk remains the benchmark. Feeding preterm infants, however, presents multiple challenges only now beginning to be faced. In the past, respiratory distress and infections were such emergencies that little attention was given to nutritional needs. While optimal rates of growth are not even now known, nor even measurements to tell what is "optimum", at least the requirements for certain growth rates which are not accompanied by undue stress can be met by pre-term fresh breast milk and specially designed formulas.
