    Study Notes

    Biological Assessment

    • Physical Examination: A component of biological assessment.
    • Biochemical Assessment: Evaluation of nutritional status through laboratory testing of bodily fluids and tissues.

      • Additional Benefits: Provides insights into internal body functions. Offers objective data on nutritional deficiencies, excesses, and metabolic imbalances.

    Validity of Biochemical Assessment

    • Accurate Data Interpretation: Requires knowledge of appropriate tests, and consideration of nutritional and non-nutritional factors influencing blood chemistries.
    • Complete Diet History: Helps interpret results as it reveals supplement usage and physical symptoms.
    • Non-Nutritional Factors: Disease processes, treatments, medications, and hydration status can influence blood and urine chemistries.

    Total Body Protein

    • Distribution: Approximately 16% of total body mass (around 11 kg in a 70 kg individual).
      • Major Pool: Skeletaal muscle (somatic protein).
      • Visceral Protein: Serum protein, erythrocytes, granulocytes, lymphocytes, organs like liver, kidney, heart, pancreas.
    • Somatic Protein: Measured by creatinine. Represents skeletal muscle protein.
    • Visceral Protein: Metabolically available proteins, like albumin and globulin.

    Protein Malnutrition

    • Definition: Condition resulting from inadequate protein intake or utilization.
    • Causes:
      • Poor Diet: Insufficient protein intake.
      • Malabsorption Disorders: Celiac disease, inflammatory bowel disease.
      • Increased Protein Needs: Pregnancy, wound healing, severe illness.
    • Consequences:
      • Muscle Wasting and Weakness: Impaired immune function, leading to infections.
      • Delayed Wound Healing.
      • Edema: Swelling due to decreased oncotic pressure.
    • Assessment Methods: Combination of biochemical markers and physical examination findings.
    • Two Forms of Protein Malnutrition:
      • Marasmus: Inadequate energy intake (energy, carbohydrate, protein, and fat). Occurs in low-income countries and patients with severe illness or prolonged food reduction. Characterized by loss of muscle mass and adipose tissue.
      • Kwashiorkor: Inadequate protein intake with increased metabolic demand. Occurs in children from specific regions of low-income countries and patients with associated diseases. Characterized by visceral protein loss and edema.

    Protein Intake and Nitrogen Balance

    • Nitrogen Balance: Compares nitrogen intake (mainly as protein) with nitrogen excretion (undigested protein, urea, and ammonia).
    • Normal, Healthy Adult: Should be in equilibrium (intake equals losses).
    • Positive Nitrogen Balance: Indicates anabolism (tissue growth and repair), often seen during child development, pregnancy, and convalescence.
    • Negative Nitrogen Balance: Indicates catabolism (tissue breakdown), occurs when:
      • Dietary intake is insufficient.
      • Essential amino acids are deficient in the diet.
      • The body is under stress (burns, injury, sepsis, cancer).
    • Nitrogen Balance Calculation: Nitrogen intake - Nitrogen output.

    Nitrogen Balance Assessment

    • Nitrogen Intake: Estimated from dietary protein intake.
    • Nitrogen Output: Measured through urinary urea nitrogen and estimated non-urinary losses.
    • Primary Use: Assessing protein status and requirements, especially in critically ill patients.
    • Limitations: Requires accurate dietary intake data and 24-hour urine collection.
    • Types:
      • Nitrogen Equilibrium: Intake equals output.
