Impact of withholding early parenteral nutrition on 2-year mortality and functional outcome in critically ill adults. Intensive Care Med 2024:10.1007/s00134-024-07546-w. [PMID: 39017697 DOI: 10.1007/s00134-024-07546-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2024] [Accepted: 06/29/2024] [Indexed: 07/18/2024]
Abstract
PURPOSE In critically ill adults, withholding parenteral nutrition until 1 week after intensive care admission (Late-PN) facilitated recovery as compared with early supplementation of insufficient enteral nutrition with parenteral nutrition (Early-PN). However, the impact on long-term mortality and functional outcome, in relation to the estimated nutritional risk, remains unclear. METHODS In this prospective follow-up study of the multicenter EPaNIC randomized controlled trial, we investigated the impact of Late-PN on 2-year mortality (N = 4640) and physical functioning, assessed by the 36-Item Short Form Health Survey (SF-36; in 3292 survivors, responding 819 [738-1058] days post-randomization). To account for missing data, we repeated the analyses in two imputed models. To identify potential heterogeneity of treatment effects, we investigated the impact of Late-PN in different nutritional risk subgroups as defined by Nutritional Risk Screening-2002-score, modified NUTrition Risk in the Critically Ill-score, and age (above/below 70 years), and we evaluated whether there was statistically significant interaction between classification to a nutritional risk subgroup and the effect of the randomized intervention. Secondary outcomes were SF-36-derived physical and mental component scores (PCS & MCS). RESULTS Two-year mortality (20.5% in Late-PN, 19.8% in Early-PN; P = 0.54) and physical functioning (70 [40-90] in both study-arms; P = 0.99) were similar in both groups, also after imputation of missing physical functioning data. Likewise, Late-PN had no impact on 2-year mortality and physical functioning in any nutritional risk subgroup. PCS and MCS were similar in both groups. CONCLUSION Late-PN did not alter 2-year survival and physical functioning in adult critically ill patients, independent of anticipated nutritional risk.

Abstract
OBJECTIVES Evidence supporting glutamine supplementation in severe adult burn patients has created a state of uncertainty due to the variability in the treatment effect reported across small and large randomized controlled trials (RCTs). We aimed to systematically review the effect of glutamine supplementation on mortality in severe adult burn patients. DATA SOURCES MEDLINE, Embase, CINAHL, and Cochrane Central were searched from inception to February 10, 2023. STUDY SELECTION RCTs evaluating the effect of enteral or IV glutamine supplementation alone in severe adult burn patients were included. DATA EXTRACTION Two reviewers independently extracted data on study characteristics, burn injury characteristics, description of the intervention between groups, adverse events, and clinical outcomes. DATA SYNTHESIS Random effects meta-analyses were performed to estimate the pooled risk ratio (RR). Trial sequential analyses (TSA) for mortality and infectious complications were performed. Ten RCTs (1,577 patients) were included. We observed no significant effect of glutamine supplementation on overall mortality (RR, 0.65, 95% CI, 0.33-1.28; p = 0.21), infectious complications (RR, 0.83; 95% CI, 0.63-1.09; p = 0.18), or other secondary outcomes. In subgroup analyses, we observed no significant effects based on administration route or burn severity. We did observe a significant subgroup effect between single and multicenter RCTs in which glutamine significantly reduced mortality and infectious complications in singe-center RCTs but not in multicenter RCTs. However, TSA showed that the pooled results of single-center RCTs were type 1 errors and further trials would be futile. CONCLUSIONS Glutamine supplementation, regardless of administration, does not appear to improve clinical outcomes in severely adult burned patients.

Abstract
PURPOSE OF REVIEW Severe burn injury causes significant metabolic changes and demands that make nutritional support particularly important. Feeding the severe burn patient is a real challenge in regard to the specific needs and the clinical constraints. This review aims to challenge the existing recommendations in the light of the few recently published data on nutritional support in burn patients. RECENT FINDINGS Some key macro- and micro-nutrients have been recently studied in severe burn patients. Repletion, complementation or supplementation of omega-3 fatty acids, vitamin C, vitamin D, antioxidant micronutrients may be promising from a physiologic perspective, but evidence of benefits on hard outcomes is still weak due to the studies' design. On the contrary, the anticipated positive effects of glutamine on the time to discharge, mortality and bacteremias have been disproved in the largest randomized controlled trial investigating glutamine supplementation in burns. An individualized approach in term of nutrients quantity and quality may proof highly valuable and needs to be validated in adequate trials. The combination of nutrition and physical exercises is another studied strategy that could improve muscle outcomes. SUMMARY Due to the low number of clinical trials focused on severe burn injury, most often including limited number of patients, developing new evidence-based guidelines is challenging. More high-quality trials are needed to improve the existing recommendations in the very next future.

Ma Z, Zhang Y, Zhang Q, Wu B. Modified Nutrition Risk in Critically ill is an effective nutrition risk screening tool in severely burned patients, compared with Nutrition Risk Screening 2002. Front Nutr 2022; 9:1007885. [PMID: 36570140 PMCID: PMC9773874 DOI: 10.3389/fnut.2022.1007885] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2022] [Accepted: 11/23/2022] [Indexed: 12/13/2022] Open
Abstract
Objective The present study aimed to evaluate the value of Modified Nutrition Risk in Critically ill (mNUTRIC) and Nutrition Risk Screening 2002 (NRS2002) in the prognosis of severely burned patients. Methods The retrospective cohort study used medical data of severely burned patients admitted to the burn center of Shanghai Ruijin Hospital between January 2015 and September 2021. Demographics, clinical characteristics, laboratory nutritional indicators, mNUTRIC score and NRS2002 score were collected and analyzed in evaluation the value of two nutrition risk screening tools. Spearman correlation analysis was carried out to show the correlation between variables. The area under receiver operating characteristic (ROC) curve was used to assess the ability of mNUTRIC and NRS2002 to predict mortality. Kaplan-Meier survival curves and log-rank tests were conducted to compare the overall survival (OS). Multivariate Cox proportional hazard regression model was used to identify risk factors for 28-day mortality of severely burned patients. Results A total of 429 adult patients with burn area larger than 30% total body surface area (TBSA) were included in this study. Incidence of nutrition risk was detected in 52.21% by mNUTRIC and 20.51% by NRS2002. However, mNUTRIC was superior to NRS2002 in predicting 28-day mortality (area under ROC curve: 0.795 vs. 0.726). Multivariate Cox regression analysis showed that high mNUTRIC [hazard ratio (HR) = 4.265, 95% CI = 1.469-12.380, P = 0.008] and TBSA (HR = 1.056, 95% CI = 1.033-1.079, P < 0.001) were independent predictors for 28-day mortality. After adjusting for covariates, high NRS2002 was not associated with 28-day mortality (P = 0.367). Conclusion The present study illustrated the effectiveness of mNUTRIC as nutrition risk screening tool among severely burned patients. Early identification of nutrition risk may help to maximize benefits of nutritional therapy by providing more aggressive nutritional therapy for patients at nutrition risk.
