Impact of daily cyclic enteral nutrition versus standard continuous enteral nutrition in critically ill patients: a study protocol for a randomised controlled trial in three intensive care units in France (DC-SCENIC). BMJ Open 2024; 14:e080003. [PMID: 38286683 PMCID: PMC10826523 DOI: 10.1136/bmjopen-2023-080003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/19/2023] [Accepted: 12/19/2023] [Indexed: 01/31/2024] Open
Abstract
INTRODUCTION Current guidelines on clinical nutrition of ventilated patients in the intensive care unit (ICU) recommend initiating continuous enteral nutrition within 48 hours of ICU admission when feasible. However, discontinuous feeding regimens, alternating feeding and fasting intervals, may have an impact on clinical and patient centred outcomes. The ongoing "Impact of daily cyclic enteral nutrition versus standard continuous enteral nutrition in critically ill patients" (DC-SCENIC) trial aims to compare standard continuous enteral feeding with daily cyclic enteral feeding over 10 hours to evaluate if implementing a fasting-mimicking diet can decrease organ failure in ventilated patients during the acute phase of ICU management. METHODS AND ANALYSIS DC-SCENIC is a randomised, controlled, multicentre, open-label trial comparing two parallel groups of patients 18 years of age or older receiving invasive mechanical ventilation and having an indication for enteral nutrition through a gastric tube. Enteral feeding is continuous in the control group and administered over 10 hours daily in the intervention group. Both groups receive isocaloric nutrition with 4 g of protein per 100 mL, and have the same 20 kcal/kg/day caloric target. The primary endpoint is the change in the Sequential Organ Failure Assessment score at 7 days compared with the day of inclusion in the study. Secondary outcomes include daily caloric and protein delivery, digestive, respiratory and metabolic tolerance as well as 28-day mortality, duration of mechanical ventilation and ventilator-free days. Outcomes will be analysed on an intention-to-treat basis. Recruitment started in June 2023 in 3 French ICU's and a sample size of 318 patients is expected by February 2026. ETHICS AND DISSEMINATION This study received approval from the national ethics review board on 8 November 2022 (Comité de Protection des Personnes Sud-Est VI, registration number 2022-A00827-36). Patients are included after informed consent. Results will be submitted for publication in peer-reviewed journals. TRIAL REGISTRATION NUMBER NCT05627167.

Abstract
Nutrition is one of the foundations for supporting and treating critically ill patients. Nutritional support provides calories, protein, electrolytes, vitamins, and trace elements via the enteral or parenteral route. Acute kidney injury (AKI) is a common and devastating problem in critically ill patients and has significant metabolic and nutritional consequences. Moreover, renal replacement therapy (RRT), whatever the modality used, also profoundly impacts metabolism. RRT and of the extracorporeal circuit impede 'effect the evaluation of a patient's energy requirements by clinicians. Substrates added and removed within the extracorporeal treatment are not always taken into consideration, making treatment even more challenging. Furthermore, evidence on nutritional support during continuous renal replacement therapy (CRRT) is scarce, and there are no clinical guidelines for nutrition adaptations during CRRT in critically ill patients. Most recommendations are based on expert opinions. This review discusses the complex interaction between nutritional support and CRRT and presents some milestones for nutritional support in critically ill patients on CRRT.

Pharmacol Res 2023; 191:106780. [PMID: 37088260 DOI: 10.1016/j.phrs.2023.106780] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/13/2023] [Revised: 04/12/2023] [Accepted: 04/21/2023] [Indexed: 04/25/2023]
Abstract
The ketogenic diet is known to be a possible adjuvant treatment in several medical conditions, such as in patients with severe or drug-resistant forms of epilepsy. Its use has recently been increasing among adolescents and young adults due to its supposed weight-loss effect, mediated by lipolysis and lowered insulin levels. However, there are still no precise indications on the possible use of ketogenic diets in pediatric age for weight loss. This approach has also recently been proposed for other types of disorder such as inherited metabolic disorders, Prader-Willi syndrome, and some specific types of cancers. Due to its unbalanced ratio of lipids, carbohydrates and proteins, a clinical evaluation of possible side effects with a strict evaluation of growth and nutritional status is essential in all patients following a long-term restrictive diet such as the ketogenic one. The prophylactic use of micronutrients supplementation should be considered before starting any ketogenic diet. Lastly, while there is sufficient literature on possible short-term side effects of ketogenic diets, their possible long-term impact on growth and nutritional status is not yet fully understood, especially when started in pediatric age.

JPEN J Parenter Enteral Nutr 2022; 46:1883-1891. [PMID: 35589384 DOI: 10.1002/jpen.2405] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2022] [Revised: 05/10/2022] [Accepted: 05/16/2022] [Indexed: 11/10/2022]
Abstract
BACKGROUND Propofol, dextrose, and citrate infusions are necessary treatment modalities in the intensive care units (ICUs). They are, however, a potential source of non-nutritive calories (NNCs) which may cause over-feeding and adverse complications. The literature surrounding the role of NNCs is limited. We aimed to examine the energy contribution of NNCs. Our secondary aim is to assess the nutritional impact of NNCs, especially among patients receiving continuous renal replacement therapy (CRRT). MATERIALS /METHODS We enrolled 177 mechanically ventilated patients admitted to medical-surgical ICUs from August to December 2019. Patients were monitored over the first 7 days of admission. Infusion rates of EN/PN and NNCs, as well as clinical characteristics, were examined. Patients receiving CRRT were compared to those without. RESULTS In total, 24% received additional energy from citrate. Patients received a maximum of 331kcal from citrate, 492kcal from propofol, and 992kcal from dextrose per ICU day. CRRT-group achieved higher total energy on the first two days (Day 1 - 55.1% vs. 46.4%; p=0.008, Day 2 - 73.2% vs. 55.4%, p=0.025). They also received higher mean NNCs on all days, except for Day 1 (p=0.068). CONCLUSION NNCs, especially citrate, are significant sources of energy. Patients receiving CRRT may have greater nutritional risk. There should be close monitoring and adaption of energy prescription accordingly to prevent over-feeding.

Abstract
Background & aims COVID-19 is a hypercatabolic disease with possible pulmonary and gastrointestinal symptoms, and consequent deterioration of the nutritional status and the worst clinical prognosis. This study presents a protocol to guide the nutritional care of adult and elderly people non-critically and critically ill with COVID-19. Methods A critical review of the literature was carried out in the databases PubMed, Scielo, Bireme, and Science Direct, in search of articles and guidelines that presented assessment criteria and nutritional conduct for COVID-19 and Severe Acute Respiratory Syndrome (SARS), as well as guidelines for managing the symptoms presented by patients. Results The results are recommendations based on the literature and the professional experience of nutritionists who provide nutritional assistance to individuals hospitalized with COVID-19 since the beginning of the pandemic in Brazil. We present tools and suggestions for assessing the nutritional status, calculating nutritional needs, initiating nutritional therapy and monitoring tolerance to it, nutritional monitoring during hospitalization, and guidelines for hospital discharge. Conclusion Patients with COVID-19 are at nutritional risk. A complete nutritional assessment (anthropometric, dietary, and laboratory assessment) enables the establishment of an individualized nutritional approach in order to contribute to better clinical and nutritional prognoses.

Abstract
Background Little is known about metabolic and nutrition characteristics of patients with coronavirus disease 2019 (COVID‐19) and persistent critical illness. We aimed to compare those characteristics in patients with PCI and COVID‐19 and patients without COVID‐19 infection (non‐CO)—primarily, their energy balance. Methods This is a prospective observational study including two consecutive cohorts, defined as needing intubation for >10 days. We collected demographic data, severity scores, nutrition variables, length of stay, and mortality. Results Altogether, 104 patients (52 per group) were included (59 ± 14 years old [mean ± SD], 75% men) between July 2019 and May 2020. SAPSII, Nutrition Risk Screening (NRS) score, proportion of obese patients, duration of intubation (18.2 ± 11.7 days), and mortality rates were similar. Patients with COVID‐19 (vs non‐CO) had lower SOFA scores (P = 0.013) and more frequently needed prone position (P < 0.0001) and neuromuscular blockade (P < 0.0001): lengths of ICU (P = 0.03) and hospital stays were shorter (P < 0.0001). Prescribed energy targets were below those of the ICU protocol. The energy balance of patients with COVID‐19 was significantly more negative after day 10. Enteral nutrition (EN) started earlier (P < 0.0001). During the first 10 days, COVID‐19 patients received more lipid (propofol sedation) and less protein. Higher admission C‐reactive protein (P = 0.002) decreased faster (P < 0.001). Whereas intestinal function was characterized by constipation in both groups during the first 10 days, diarrhea was less common in patients with COVID‐19 thereafter. Conclusion Compared with non‐CO patients, COVID‐19 patients were not more obese, had lower SOFA scores, and were fed more rapidly with EN, because of a more normal gastrointestinal function possibly due to fewer non–respiratory organ failures: their energy balances were more negative after the first 10 days. Propofol sedation reduced protein delivery.

Abstract
Background: While consent exists, that nutritional status has prognostic impact in the critically ill, the optimal feeding strategy has been a matter of debate. Methods: Narrative review of the recent evidence and international guideline recommendations focusing on basic principles of nutrition in the ICU and the treatment of specific patient groups. Covered topics are: the importance and diagnosis of malnutrition in the ICU, the optimal timing and route of nutrition, energy and protein requirements, the supplementation of specific nutrients, as well as monitoring and complications of a Medical Nutrition Therapy (MNT). Furthermore, this review summarizes the available evidence to optimize the MNT of patients grouped by primarily affected organ system. Results: Due to the considerable heterogeneity of the critically ill, MNT should be carefully adapted to the individual patient with special focus on phase of critical illness, metabolic tolerance, leading symptoms, and comorbidities. Conclusion: MNT in the ICU is complex and requiring an interdisciplinary approach and frequent reevaluation. The impact of personalized and disease-specific MNT on patient-centered clinical outcomes remains to be elucidated.

Impact of Propofol Sedation upon Caloric Overfeeding and Protein Inadequacy in Critically Ill Patients Receiving Nutrition Support. PHARMACY 2021; 9:pharmacy9030121.

Abstract
Propofol, a commonly used sedative in the intensive care unit, is formulated in a 10% lipid emulsion that contributes 1.1 kcals per mL. As a result, propofol can significantly contribute to caloric intake and can potentially result in complications of overfeeding for patients who receive concurrent enteral or parenteral nutrition therapy. In order to avoid potential overfeeding, some clinicians have empirically decreased the infusion rate of the nutrition therapy, which also may have detrimental effects since protein intake may be inadequate. The purpose of this review is to examine the current literature regarding these issues and provide some practical suggestions on how to restrict caloric intake to avoid overfeeding and simultaneously enhance protein intake for patients who receive either parenteral or enteral nutrition for those patients receiving concurrent propofol therapy.

Abstract
Propofol is an oily liquid widely used for rapid onset of anaesthesia via intravenous route, which shows major limitations of hypersensitivity, anaphylactic reactions and pain. The aim of the present work was to bypass the above issues by formulating tailored niosomal gel to deliver propofol via non-invasive transdermal route. The niosomes were prepared by film hydration method and sonication using cholesterol and Span 80. The Box Behnken design (BBD) was applied to optimize the size (93.5 nm) and the entrapment efficacy (81.5%) of the niosomes by selecting cholesterol at 139 mg, Span 80 at 0.525% and sonication time at 5.13 min. The scanning electron microscopy image showed spherical shape niosomes with smooth surface without aggregation. The ex vivo release data showed significant improvement in the propofol release (92.2% after 10 h) using niosomes in comparison to the control propofol gel (with 30% methanol) without niosomes (25.3% after 10 h). The in vivo pharmacokinetic parameters in the rat model confirmed the improvement in the relative bioavailability with optimized niosomal gel (relative bioavailability = 12.12) in comparison to the control propofol gel. In conclusion, the niosomal gel offered a potential alternative non-invasive route to deliver propofol for procedural sedation especially in pediatric population.

Abstract
Patients undergoing targeted temperature management (TTM) after cardiac arrest are at risk for shivering, which increases energy expenditure (EE) and may attenuate TTM benefits. This article reports patterns of EE for patients with and without shivering who received TTM at 36°C after cardiac arrest. Based on 96 case assessments, there were 14 occasions when more than one 15-minute interval period was required to appropriately modify the Bedside Shivering Assessment Scale (BSAS) score. Investigators noted that although higher EE was related to higher BSAS scores, there may be opportunities for earlier detection of shivering.

Abstract
BACKGROUND Nutritional support in the critically ill aims to avoid under and overfeeding, adjusting to changes in energy expenditure during critical illness. The sedation propofol provides significant fat and energy load. We investigated whether changing from 1% to a 2% propofol, would decrease non-nutritional energy, avoid energy overfeeding and increase the amount of protein delivered. METHODS A retrospective observational study was performed. The primary outcome was protein delivery. Secondary outcomes were energy from propofol fat and the total energy delivered from nutrition and propofol. RESULTS In total, 100 patients were investigated, with 50 patients in each group. The propofol dose was comparable for each group. The nutrition energy prescribed was significantly less for the 1% compared to 2% group, taking the energy from propofol into consideration. Both groups had similar protein targets, although the amount delivered was significantly higher in the 2% group. Thirty-six percent of individuals receiving 1% exceeded 45% of total energy from fat. The poor delivery of nutrition resulted in inadequate energy and protein, irrespective of propofol dose. CONCLUSIONS We investigated the impact of propofol on energy overfeeding and under delivery of protein, and highlighted suboptimal nutritional provision. Work is needed to investigate the harm that high-fat delivery may pose in light of poor nutrition delivery.

Abstract
BACKGROUND Patients with traumatic brain (TBI) injury often require a high dosage of propofol, which can provide an excessive caloric intake. We evaluated our strategy of using liquid protein supplement boluses concurrently with high protein-containing enteral nutrition (EN) formulas and formula rate reduction to avoid caloric overfeeding and inadequate protein intake. METHODS Adult patients (aged >17 years) with TBI admitted to the trauma intensive care unit (TICU) who received concurrent propofol and EN were retrospectively reviewed. Caloric intakes from propofol and EN were obtained. Actual protein intake was compared with projected protein intakes from high protein content and standard protein content enteral formulas when given at an isocaloric intake. RESULTS Fifty-one patients were enrolled. Average caloric intake from propofol was 356 ± 243 kcal/d or 5 ± 3 kcal/kg/d (range, <1-15 kcal/kg/d). Daily EN caloric intake ranged from 7 ± 4 kcal/kg/d (day 2) to 16 ± 9 kcal/kg/d (day 5; P < .001). Average protein intake ranged from 0.6 ± 0.4 g/kg/d (day 2) to 1.5 ± 0.7 g/kg/d (day 5; P < .001). The modified EN strategy resulted in daily delivery of 24%-38% more protein than an isocaloric regimen with a high protein-content formula and twice as much protein than the standard protein-content formula (P < .001). CONCLUSION The strategy of providing an EN regimen comprised liquid protein boluses, and high and very high protein-containing EN formulas at a reduced rate improved protein delivery without caloric overfeeding.

Abstract
PURPOSE OF REVIEW Any critical care therapy requires individual adaptation, despite standardization of the concepts supporting them. Among these therapies, nutrition care has been repeatedly shown to influence clinical outcome. Individualized feeding is the next needed step towards optimal global critical care. RECENT FINDINGS Both underfeeding and overfeeding generate complications and should be prevented. The long forgotten endogenous energy production, maximal during the first 3 to 4 days, should be integrated in the nutrition plan, through a slow progression of feeding, as full feeding may result in early overfeeding. Accurate and repeated indirect calorimetry is becoming possible thanks to the recent development of a reliable, easy to use and affordable indirect calorimeter. The optimal timing of the prescription of the measured energy expenditure values as goal remains to be determined. Optimal protein prescription remains difficult as no clinically available tool has yet been identified reflecting the body needs. SUMMARY Although energy expenditure can now be measured, we miss indicators of early endogenous energy production and of protein needs. A pragmatic ramping up of extrinsic energy provision by nutrition support reduces the risk of overfeeding-related adverse effects.

Abstract
Nutrition therapy during critical illness has been a focus of recent research, with a rapid increase in publications accompanied by two updated international clinical guidelines. However, the translation of evidence into practice is challenging due to the continually evolving, often conflicting trial findings and guideline recommendations. This narrative review aims to provide a comprehensive synthesis and interpretation of the adult critical care nutrition literature, with a particular focus on continuing practice gaps and areas with new data, to assist clinicians in making practical, yet evidence-based decisions regarding nutrition management during the different stages of critical illness.

Abstract
PURPOSE Enteral and parenteral nutrition of adult critically ill patients varies in terms of the route of nutrient delivery, the amount and composition of macro- and micronutrients, and the choice of specific, immune-modulating substrates. Variations of clinical nutrition may affect clinical outcomes. The present guideline provides clinicians with updated consensus-based recommendations for clinical nutrition in adult critically ill patients who suffer from at least one acute organ dysfunction requiring specific drug therapy and/or a mechanical support device (e.g., mechanical ventilation) to maintain organ function. METHODS The former guidelines of the German Society for Nutritional Medicine (DGEM) were updated according to the current instructions of the Association of the Scientific Medical Societies in Germany (AWMF) valid for a S2k-guideline. According to the S2k-guideline classification, no systematic review of the available evidence was required to make recommendations, which, therefore, do not state evidence- or recommendation grades. Nevertheless, we considered and commented the evidence from randomized-controlled trials, meta-analyses and observational studies with adequate sample size and high methodological quality (until May 2018) as well as from currently valid guidelines of other societies. The liability of each recommendation was described linguistically. Each recommendation was finally validated and consented through a Delphi process. RESULTS In the introduction the guideline describes a) the pathophysiological consequences of critical illness possibly affecting metabolism and nutrition of critically ill patients, b) potential definitions for different disease phases during the course of illness, and c) methodological shortcomings of clinical trials on nutrition. Then, we make 69 consented recommendations for essential, practice-relevant elements of clinical nutrition in critically ill patients. Among others, recommendations include the assessment of nutrition status, the indication for clinical nutrition, the timing and route of nutrient delivery, and the amount and composition of substrates (macro- and micronutrients); furthermore, we discuss distinctive aspects of nutrition therapy in obese critically ill patients and those treated with extracorporeal support devices. CONCLUSION The current guideline provides clinicians with up-to-date recommendations for enteral and parenteral nutrition of adult critically ill patients who suffer from at least one acute organ dysfunction requiring specific drug therapy and/or a mechanical support device (e.g., mechanical ventilation) to maintain organ function. The period of validity of the guideline is approximately fixed at five years (2018-2023).

Abstract
BACKGROUND To meet protein needs in critical illness (CI), guidelines suggest ≥1.2-2.5 g protein/kg/d; however, most intensive care unit (ICU) patients receive ≤0.7 g/kg/d. Higher protein enteral nutrition (EN) formulas may be part of the solution to provide prescribed protein. Our objective was to demonstrate that an EN formula with 37% protein can deliver ≥80% of prescribed protein, without overfeeding calories within the first 5 days of feeding and to describe ICU clinicians' experience. METHODS This quality improvement (QI) project included patients requiring exclusive EN for up to 5 days from 6 Canadian ICUs. Rationale for choosing formula, patient's BMI (kg/m2 ), nutrition targets, daily protein and energy delivered, feeding interruptions, and general tolerance were recorded. RESULTS Forty-four of 49 patients received the formula ≥2 days. Average protein prescribed was 137.5 g/d (82.5-200) or 1.9 g/kg/d (1.5-2.5). Average protein delivered was 116.9 g/d (33.5-180) or 1.6 g/kg/d (0.4-2.4). Seventy-five percent to 83% of patients received ≥80% prescribed protein on days 2-5. Average energy prescribed was 1638.6 kcal/d (990-2500) or 17.8 kcal/kg (11-26). Average energy delivered was 1523.9 kcal/d (693.0-2557.5) or 17.3 kcal/kg/d (1.35-64.7). The formula was well tolerated with no gastrointestinal symptoms reported in 38 (86%) patients. The most common reasons to prescribe the formula were obesity and use of fat-based medications. CONCLUSIONS We demonstrated in a QI study that a high-protein EN formula was tolerated in a small, heterogeneous group of ICU patients and effective in meeting protein targets without overfeeding.

Abstract
BACKGROUND Although propofol is widely used for sedation in intensive care units around Australia, evaluation of bedside nursing practices of the administration of propofol have been limited. We investigated whether there was a discrepancy between the amount of propofol delivered by the infusion pump and that recorded electronically and consequently patient exposure to avoidable harms. AIMS The aim of this research was to compare the total amount of propofol administered to intensive care patients via a programmable infusion pump with that documented in the electronic medical record (EMR). Secondary objectives were to ascertain the percentage of 1) patients exposed to a propofol dose greater than recommended and 2) daily energy requirements administered as propofol infusion. METHODS This was a prospective, observational study of total propofol delivered to 50 patients in a 14-bed metropolitan, Australian intensive care unit. Infusion pump data and entries from the EMR were collated. RESULTS Propofol sedation was administered for a median 18 (interquartile range: 14-47) hours with median total propofol 3025 mg (interquartile range: 1840-7755 mg) by pump and 3250 mg (interquartile range: 1915-6960 mg) by EMR, i.e. 1.9 (interquartile range: 1.3-2.3) mg/kg/hour by pump (correlation coefficient = 0.99). The total bolus propofol documented in the EMR was a median 330 mg (interquartile range: -838 to -124) less than the pump amount. Nineteen (38%) patients had no EMR-documented propofol boluses yet had received at least one bolus via the pump. In two of 50 (4%) patients, the pump propofol infusion dose was above the recommended maximum safe dose of 4 mg/kg/h. CONCLUSION In this cohort of patients, the bolus administration of propofol was frequently not documented, potentially placing some patients at risk of drug-related toxicity. Further research to develop and implement strategies to improve the documentation of propofol administration is indicated.

Abstract
Introduction Nutrition is an important part of treatment in critically ill children. Clinical guidelines for nutrition adaptations during continuous renal replacement therapy (CRRT) are lacking. We collected and evaluated current knowledge on this topic and provide recommendations. Methods Questions were produced to guide the literature search in the PubMed database. Results Evidence is scarce and extrapolation from adult data was often required. CRRT has a direct and substantial impact on metabolism. Indirect calorimetry is the preferred method to assess resting energy expenditure (REE). Moderate underestimation of REE is common but not clinically relevant. Formula‐based calculation of REE is inaccurate and not validated in critically ill children on CRRT. The nutrition impact of nonintentional calories delivered as citrate, lactate, and glucose during CRRT must be considered. Quantifying nitrogen balance is not feasible during CRRT. Protein delivery should be increased by 25% to compensate for losses in the effluent. Fats are not removed by CRRT and should not be adapted during CRRT. Electrolyte disturbances are frequently present and should be treated accordingly. Vitamins B1, B6, B9, and C are lost in the effluent and should be adapted to the effluent dose. Trace elements, with the exception of selenium, are not cleared in relevant quantities. Manganese accumulation is of concern because of potential neurotoxicity. Conclusion Current recommendations regarding nutrition support in pediatric CRRT must be extrapolated from adult studies. Recommendations are provided, based on the weak level of evidence. Additional research on this topic is warranted.

Abstract
The feeding of critically ill patients has recently become a controversial issue, as several studies have provided unexpected and contradictory results. Earlier beliefs regarding energy requirements in critical illness-especially during the initial phase-have been challenged. In the current review, we summarize existing evidence about fasting and the impact of early vs. late feeding on the sick organism's responses. The most important points are the non-nutritional advantages of using the intestine, and recognition that early endogenous energy production as an important player in the response must be integrated in the nutrient prescription. There is as of yet no bedside tool to monitor dynamics in metabolism and the magnitude of the endogenous energy production. Hence, an early "full-feeding strategy" exposes patients to involuntary overfeeding, due to the absence of an objective measure enabling the adjustment of the nutritional therapy. Suggestions for future research and clinical practice are proposed.
