ABSTRACT
Background: Previous studies have shown that malnutrition before hematopoietic stem cell transplantation (HSCT) is associated with poor patient prognoses. There is inconsistency among studies on which nutritional status screening tool is appropriate for malnutrition diagnosis before allo-HSCT. The present study aimed to compare nutritional screening tools in patients with leukemia before allo-HSCT. Methods: An observational, cross-sectional, and single-center study was conducted in Tehran, Iran. One hundred four adults allo-HSCT candidates aged 18-55 years with leukemia were selected sequentially. Malnutrition assessment was done using three tools, the Global Leadership Initiative on Malnutrition (GLIM), nutritional risk screening 2002 (NRS-2002) and European Society for Clinical Nutrition and Metabolism (ESPEN) criteria. The agreement between malnutrition assessment tools was evaluated with Cohen's kappa. Results: The agreement between GLIM and NRS-2002 was perfect (κ = 0.817, p < 0.001), while the agreement between GLIM and ESPEN was fair (κ = 0.362, p < 0.001). The agreement between NRS-2002 and ESPEN was fair (κ = 0.262, p < 0.001). We also found a moderate agreement for all tools (κ = 0.489, p < 0.001). Conclusion: NRS-2002 is an accepted tool for screening malnutrition in hospitalized patients. In the current study, the GLIM criterion perfectly agreed with the NRS-2002. Further studies in the HSCT setting are needed to introduce a valid tool.
ABSTRACT
CONTEXT: To date, the efficacy of nutritional interventions on oral mucositis (OM) in patients with cancer, and the quality of this evidence have not been explored. OBJECTIVE: The goal of this umbrella review was to provide a comprehensive evaluation of nutritional interventions for patients with cancer with OM, as well as to assess the quality of this evidence. DATA SOURCES: Meta-analyses were searched for using PubMed, Scopus, and ISI Web of Science databases until December 2021, with no time restrictions. DATA EXTRACTION: Meta-analyses of randomized control trials that evaluated the effects of nutritional interventions on the incidence of OM in patients with cancer had inclusion criteria for this umbrella review. Data extraction, quality assessment of meta-analyses, and primary studies were done independently by 2 authors. The Grading of Recommendations Assessment, Development, and Evaluation technique was used to grade the certainty of evidence. DATA ANALYSIS: A total of 26 meta-analyses were included in this umbrella review. The results showed that honey, glutamine, and propolis can reduce the incidence of severe OM, based on moderate evidence quality. In addition, zinc supplementation significantly reduced the incidence of OM, regardless of symptom severity; however, low certainty of the evidence was observed. The effects of vitamin E, curcumin, and probiotics on OM were not statistically significant. CONCLUSION: This umbrella review shows that honey, glutamine, and propolis can significantly reduce the incidence of severe OM. These findings need to be confirmed with well-designed, longitudinal randomized controlled trials. SYSTEMATIC REVIEW REGISTRATION: PROSPERO registration no. CRD42022301010.
