Summary

This study identified key nutritional parameters like mid-arm circumference, serum albumin, and lymphocyte count as predictors of mortality in patients. A prognostic nutritional index (PNI) below 116 indicated a higher risk group with increased mortality.

Area of Science:

  • Clinical Nutrition
  • Biostatistics
  • Prognostic Biomarkers

Context:

  • Prospective study conducted at Hospital Rawson and Hospital Aeronáutico.
  • Evaluated 104 patients and 35 healthy controls over one month.
  • Utilized statistical analyses including Student's t-test, ANOVA, and Chi-squared test.

Purpose:

  • To identify mortality predicting parameters in patients.
  • To establish a prognostic nutritional index (PNI) for risk stratification.
  • To assess the correlation between nutritional status and patient outcomes.

Summary:

  • Mid-arm circumference (MAC), serum albumin (SA), and absolute lymphocyte count (ALC) were found to correlate with mortality (p<0.05).
  • A prognostic nutritional index (PNI) was calculated as sqrt(ALC) + (SA x MAC).

  • Patients with a PNI ≤ 116 exhibited a 12.20% mortality rate, while those with PNI ≥ 117 had no mortality.

    • Impact:

    • Highlights the significance of nutritional assessment in predicting patient mortality.
    • Suggests that nutritional support should be prioritized for high-risk patient groups.
    • Provides a validated prognostic nutritional index for clinical application.
