    Study Notes

    Infant Growth

    • Infants increase in length by 50% within the first year of life.

    Childhood & Adolescent Growth

    • Growth is slow but constant during the preschool years (Ages 2-6).
    • Adipose tissue distribution begins around the age of 2.
    • Steady growth occurs during middle childhood (Ages 7-10).
    • Females are generally taller and heavier than males in height and weight during middle childhood.
    • Adolescence (Ages 11-18) involves rapid growth in height and weight.
    • Males are generally taller and heavier than females in height and weight during adolescence.

    Nutritional Assessment

    • Risk Factors: Used to identify potential malnutrition.
    • History: Medical and dietary history are crucial.
    • Anthropometrics: Measurements like height, weight, and head circumference are used to assess growth.
    • Classification of Malnutrition: Determines the severity of malnutrition.
    • Nitrogen Balance: Assesses protein intake and utilization through a 24-hour urine collection.

    Visceral Protein Status

    • Albumin: Normal range is 3.5-5 g/dL.
    • Transferrin: Normal range is 250-300 mg/dL.
    • Transthyretin (Pre-albumin): Normal range is 15-40 mg/dL.
    • Retinol-binding protein: Normal range is 2.5-7.5 mg/dL.
    • C-Reactive Protein (CRP): A positive acute phase reactant (increased by at least 25% during inflammation).
      • Normal range is <1 mg/dL.
      • Used to assess the accuracy of pre-albumin measurement.
      • Pre-albumin levels can be falsely low due to inflammation.

    Protein Requirements

    • Intact protein: Requires complete digestion into smaller peptides.
    • Partially digested (peptide-based): Easier for the body to utilize, beneficial for patients with mal-absorption and diarrhea.
    • Modular supplements: Provide customized nutritional support.

    Glutamine

    • A conditionally essential amino acid that plays a critical role in gut health and immune function.

    Probiotics

    • Live microorganisms that confer health benefits to the host.
    • May inhibit pathogenic bacterial growth, block pathogen attachment, eliminate toxins, and enhance the host inflammatory response.

    Vitamin & Trace Elements

    • Used for antioxidant effects and repletion.
    • Vitamin E & C are important for immune function.

    Acute Renal Failure

    • Adjust enteral formula based on electrolyte profile.
    • Avoid viscous formulations like syrups, mineral oil, and granules due to the risk of tube clogging.
    • Crush tablets or open capsules and dilute in 15-30mL of sterile water.

    Hepatic Failure

    • Traditional nutritional assessment tools may be inaccurate.
    • Branched-chain amino acids (BCAAs) may be beneficial for patients with encephalopathy refractory to other treatments.

    Pulmonary Failure

    • Fluid-restriction and calorically dense formulations are often employed (1.5-2.0 kcal/mL).
