Abstract
OBJECTIVE To determine the associations of stress ulcer prophylaxis with gastrointestinal (GI) bleeding, nosocomial pneumonia (NP), mortality, and length of stay in the pediatric intensive care unit (PICU). STUDY DESIGN We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) and observational studies in the English language assessing the effects of proton pump inhibitors and histamine-2 receptor antagonists on patients in the PICU published before October 2018 from the PubMed, Embase, CINAHL, and Cochrane Central Register of Controlled Trials databases. A random-effects Mantel-Haenszel risk difference (MHRD) model was used to pool all the selected studies for meta-analysis. Primary outcomes were the incidences of GI bleeding and NP. Secondary outcomes included mortality and length of PICU stay. RESULTS Seventeen studies (4 RCTs and 13 observational studies) with a total of 340 763 patients were included. The overall incidence of GI bleeding was 15.2%. There was no difference in the risk of GI bleeding based on stress ulcer prophylaxis status (MHRD, 5.0%; 95% CI, -1.0% to 11.0%; I2 = 62%). There was an increased risk of NP in patients who received stress ulcer prophylaxis compared with those who did not (MHRD, 5.3%; 95% CI, 3.5%-7.0%; I2 = 0%). An increased risk of mortality was seen in patients receiving stress ulcer prophylaxis (MHRD, 2.1%; 95% CI, 2.0%-2.2%; I2 = 0%), although this association was no longer found when 1 large study was removed in a sensitivity analysis. There was no statistically significant difference in length of PICU stay between the groups (standardized mean difference, 0.42 days; 95% CI, -0.16 to 1.01 days; I2 = 89.8%). CONCLUSIONS Stress ulcer prophylaxis does not show a clear benefit in reducing GI bleeding or length of PICU stay. Observational studies suggest an increased risk of NP and mortality with stress ulcer prophylaxis, which remains to be validated in clinical trials.

Translating the European Society for Clinical Nutrition and Metabolism 2019 guidelines into practice.
Reintam Blaser, A, Deane, AM, Starkopf, J
Current opinion in critical care. 2019;(4):314-321
Abstract
PURPOSE OF REVIEW To present a pragmatic approach to facilitate clinician's implementing the recent European Society for Clinical Nutrition and Metabolism (ESPEN) guidelines on clinical nutrition in the intensive care unit. RECENT FINDINGS The ESPEN guidelines include 54 recommendations with a rationale for each recommendation. All data published since 1 January 2000 was reviewed and 31 meta-analyses were performed to inform these guidelines. An important aspect of the most recent ESPEN guidelines is an attempt to separate periods of critical illness into discrete - early acute, late acute and recovery - phases, with each exhibiting different metabolic profiles and requiring different strategies for nutritional and metabolic support. SUMMARY A pragmatic approach to incorporate the recent ESPEN guidelines into everyday clinical practice is provided.

Alipoor, E, Hosseinzadeh-Attar, MJ, Yaseri, M, Maghsoudi-Nasab, S, Jazayeri, S
International journal of obesity (2005). 2019;(4):641-651
Abstract
Recent studies have suggested that obesity might be protective in specific conditions such as critical illness; however, there are controversial data in critically ill children with obesity. The aim of this study was to investigate the association of obesity with mortality and other outcomes in these patients. We conducted a systematic review of observational studies investigating obesity in critically ill children, published by August 2017 in PubMed and Scopus. After screening documents, 15 articles with 142119 patients were included in the systematic review and meta-analysis. The results were reported with odds ratio (OR) or standard mean difference (SMD). The primary outcome was mortality and the secondary outcomes were length of ICU stay (ICU LOS), length of hospital stay (hospital LOS), and duration of mechanical ventilation (MV). The analysis showed that critically ill children without obesity had lower risk of mortality compared to patients with obesity (OR 0.79, 95% CI 0.64 to 0.97, P = 0.025, I2 = 35.2%). Hospital LOS was also significantly lower in children without obesity (pooled SMD -0.12, 95% CI -0.21 to -0.04, P = 0.004, I2 = 8.1%). There were no differences in ICU LOS (95% CI -0.19 to 0.01, P = 0.083) and duration of MV (95% CI -0.22 to 0.03, P = 0.136) between critically ill children with and without obesity. In conclusion, the current systematic review and meta-analysis revealed that critically ill children with obesity have higher risk of mortality and length of hospital stay compared to the group without obesity. Further prospective studies are essential to elucidate the role of obesity and underlying mechanisms in predicting outcomes of critically ill children.

Abstract
BACKGROUND Early enteral nutrition support (within 48 hours of admission or injury) is frequently recommended for the management of patients in intensive care units (ICU). Early enteral nutrition is recommended in many clinical practice guidelines, although there appears to be a lack of evidence for its use and benefit. OBJECTIVES To evaluate the efficacy and safety of early enteral nutrition (initiated within 48 hours of initial injury or ICU admission) versus delayed enteral nutrition (initiated later than 48 hours after initial injury or ICU admission), with or without supplemental parenteral nutrition, in critically ill adults. SEARCH METHODS We searched CENTRAL (2019, Issue 4), MEDLINE Ovid (1946 to April 2019), Embase Ovid SP (1974 to April 2019), CINAHL EBSCO (1982 to April 2019), and ISI Web of Science (1945 to April 2019). We also searched Turning Research Into Practice (TRIP), trial registers (ClinicalTrials.gov, ISRCTN registry), and scientific conference reports, including the American Society for Parenteral and Enteral Nutrition and the European Society for Clinical Nutrition and Metabolism. We applied no restrictions by language or publication status. SELECTION CRITERIA We included all randomized controlled trials (RCTs) that compared early versus delayed enteral nutrition, with or without supplemental parenteral nutrition, in adults who were in the ICU for longer than 72 hours. This included individuals admitted for medical, surgical, and trauma diagnoses, and who required any type of enteral nutrition. DATA COLLECTION AND ANALYSIS Two review authors extracted study data and assessed the risk of bias in the included studies. We expressed results as risk ratios (RR) for dichotomous data, and as mean differences (MD) for continuous data, both with 95% confidence intervals (CI). We assessed the certainty of the evidence using GRADE. MAIN RESULTS We included seven RCTs with a total of 345 participants. Outcome data were limited, and we judged many trials to have an unclear risk of bias in several domains. Early versus delayed enteral nutrition Six trials (318 participants) assessed early versus delayed enteral nutrition in general, medical, and trauma ICUs in the USA, Australia, Greece, India, and Russia. Primary outcomes Five studies (259 participants) measured mortality. It is uncertain whether early enteral nutrition affects the risk of mortality within 30 days (RR 1.00, 95% CI 0.16 to 6.38; 1 study, 38 participants; very low-quality evidence). Four studies (221 participants) reported mortality without describing the timeframe; we did not pool these results. None of the studies reported a clear difference in mortality between groups. Three studies (156 participants) reported infectious complications. We were unable to pool the results due to unreported data and substantial clinical heterogeneity. The results were inconsistent across studies. One trial measured feed intolerance or gastrointestinal complications; it is uncertain whether early enteral nutrition affects this outcome (RR 0.84, 95% CI 0.35 to 2.01; 59 participants; very low-quality evidence). Secondary outcomes One trial assessed hospital length of stay and reported a longer stay in the early enteral group (median 15 days (interquartile range (IQR) 9.5 to 20) versus 12 days (IQR 7.5 to15); P = 0.05; 59 participants; very low-quality evidence). Three studies (125 participants) reported the duration of mechanical ventilation. We did not pool the results due to clinical and statistical heterogeneity. The results were inconsistent across studies. It is uncertain whether early enteral nutrition affects the risk of pneumonia (RR 0.77, 95% CI 0.55 to 1.06; 4 studies, 192 participants; very low-quality evidence). Early enteral nutrition with supplemental parenteral nutrition versus delayed enteral nutrition with supplemental parenteral nutrition We identified one trial in a burn ICU in the USA (27 participants). Primary outcomes It is uncertain whether early enteral nutrition with supplemental parenteral nutrition affects the risk of mortality (RR 0.74, 95% CI 0.25 to 2.18; very low-quality evidence), or infectious complications (MD 0.00, 95% CI -1.94 to 1.94; very low-quality evidence). There were no data available for feed intolerance or gastrointestinal complications. Secondary outcomes It is uncertain whether early enteral nutrition with supplemental parenteral nutrition reduces the duration of mechanical ventilation (MD 9.00, 95% CI -10.99 to 28.99; very low-quality evidence). There were no data available for hospital length of stay or pneumonia. AUTHORS' CONCLUSIONS Due to very low-quality evidence, we are uncertain whether early enteral nutrition, compared with delayed enteral nutrition, affects the risk of mortality within 30 days, feed intolerance or gastrointestinal complications, or pneumonia. Due to very low-quality evidence, we are uncertain if early enteral nutrition with supplemental parenteral nutrition compared with delayed enteral nutrition with supplemental parenteral nutrition reduces mortality, infectious complications, or duration of mechanical ventilation. There is currently insufficient evidence; there is a need for large, multicentred studies with rigorous methodology, which measure important clinical outcomes.

Zhu, XM, Qian, SY, Lu, GP, Xu, F, Wang, Y, Liu, CF, Ren, XX, Zhang, YC, Gao, HM, Zhou, T, et al
World journal of pediatrics : WJP. 2018;(5):419-428
Abstract
BACKGROUND This document represents the first evidence-based guidelines to describe best practices in nutrition therapy in critically ill children (> 1 month and < 18 years), who are expected to require a length of stay more than 2 or 3 days in a Pediatric Intensive Care Unit admitting medical patients domain. METHODS A total of 25,673 articles were scanned for relevance. After careful review, 88 studies appeared to answer the pre-identified questions for the guidelines. We used the grading of recommendations, assessment, development and evaluation criteria to adjust the evidence grade based on the quality of design and execution of each study. RESULTS The guidelines emphasise the importance of nutritional assessment, particularly the detection of malnourished patients. Indirect calorimetry (IC) is recommended to estimate energy expenditure and there is a creative value in energy expenditure, 50 kcal/kg/day for children aged 1-8 years during acute phase if IC is unfeasible. Enteral nutrition (EN) and early enteral nutrition remain the preferred routes for nutrient delivery. A minimum protein intake of 1.5 g/kg/day is suggested for this patient population. The role of supplemental parenteral nutrition (PN) has been highlighted in patients with low nutritional risk, and a delayed approach appears to be beneficial in this group of patients. Immune-enhancing cannot be currently recommended neither in EN nor PN. CONCLUSION Overall, the pediatric critically ill population is heterogeneous, and an individualized nutrition support with the aim of improving clinical outcomes is necessary and important.
