Zheng P, Chen Y, Chen F, Zhou M, Xie C. Risk factors for the development of refeeding syndrome in adults: A systematic review. Nutr Clin Pract 2024. [PMID: 39187889 DOI: 10.1002/ncp.11203] [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: 11/04/2023] [Revised: 07/18/2024] [Accepted: 08/01/2024] [Indexed: 08/28/2024] Open
Abstract
Identifying patients with a particularly high risk of refeeding syndrome (RFS) is essential for taking preventive measures. To guide the development of clinical decision-making and risk prediction models or other screening tools for RFS, increased knowledge of risk factors is needed. Therefore, we conducted a systematic review to identify risk factors for the development of RFS. PubMed, EMBASE, Cochrane Library, and Web of Science were searched from January 1990 until March 2023. Studies investigating demographic, clinical, drug use, laboratory, and/or nutrition factors for RFS were considered. The Newcastle-Ottawa Scale was used to appraise the methodological quality of included studies. Of 1589 identified records, 30 studies were included. Thirty-three factors associated with increased risk of RFS after multivariable adjustments were identified. The following factors were reported by two or more studies, with 0-1 study reporting null findings: a previous history of alcohol misuse, cancer, comorbid hypertension, high Acute Physiology and Chronic Health Evaluation II score, high Sequential Organ Failure Assessment score, low Glasgow coma scale score, the use of diuretics before refeeding, low baseline serum prealbumin level, high baseline level of creatinine, and enteral nutrition. The majority of the studies (20, 66.7%) were of high methodological quality. In conclusion, this systematic review informs on several risk factors for RFS in patients. To improve risk stratification and guide development of risk prediction models or other screening tools, further confirmation is needed because there were a small number of studies and a low number of high-quality studies on each factor.

Abstract
Severe eating disorders may develop refeeding syndrome, which sometimes resembles severe cardiac dysfunction. A woman in her thirties was admitted to our hospital because of cardiogenic shock. Transthoracic echocardiography showed reduced left ventricular systolic function. In her medical history, she had been diagnosed with refeeding syndrome. A ventricular endocardial biopsy was performed to exclude other cardiac diseases. A histological examination showed conspicuously atrophied cardiomyocytes with nuclear swelling and irregularities; the myocardial sequence was disturbed with fibrosis. Immunostaining revealed that lipid droplet markers, adipose triglyceride lipase, and perilipin 2 were poorly observed in the cardiomyocytes, while expression of both proteins was attenuated in fibroblasts within the myocardial layer. The abnormal metabolism of fatty acids was the presumed cause of cardiac dysfunction.

J Formos Med Assoc 2024:S0929-6646(24)00286-9. [PMID: 38880709 DOI: 10.1016/j.jfma.2024.06.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2023] [Revised: 05/31/2024] [Accepted: 06/12/2024] [Indexed: 06/18/2024] Open
Abstract
BACKGROUND Phosphorus is a vital mineral crucial for various physiological functions. Critically ill trauma patients frequently experience hypophosphatemia during the immediate post-traumatic phase, potentially impacting outcomes. This study aims to investigate the incidence of early hypophosphatemia in critically major trauma patients. METHODS In this prospective observational study, trauma patients admitted to the intensive care unit (ICU) within one day were enrolled. These patients were categorized into Hypo-P groups and Non-hypo groups based on the development of new-onset hypophosphatemia within 72 h after feeding. The primary outcome assessed was the incidence of new-onset hypophosphatemia. The secondary outcomes included ICU and hospital stay, ventilation duration, and mortality. RESULTS 76.1% of patients developed a new onset of hypophosphatemia within 72 h after feeding. The Hypo-P group had significantly longer ICU stays (8.1 days ± 5.5 vs. 4.4 days ± 3.1; p = 0.0251) and trends towards extended hospital stay, ventilation duration, and higher mortality. Additionally, they demonstrated significantly higher urine fractional excretion of phosphate (FEPO4) on the first ICU day (29.2% ± 14.23 vs. 19.5% ± 8.39; p = 0.0242). CONCLUSION Critically ill trauma patients exhibited a significantly higher incidence of early hypophosphatemia than typical ICU rates, indicating their heightened vulnerability. The significantly high urine FEPO4 underscores the crucial role of renal loss in disrupting phosphate metabolism in this early acute phase after trauma. A significant correlation was observed between hypophosphatemia and longer ICU stays. Monitoring and managing phosphate levels may influence outcomes, warranting further investigation.

Abstract
BACKGROUND & AIMS Refeeding syndrome (RFS) lacks both a global definition and diagnostic criteria. Different diagnostic criteria are used; serum phosphate (traditional criterion (TC)), the Friedli consensus recommendations, and the ASPEN. We investigated the incidence of RFS in older hospitalized patients and the mortality rates in patients with or without RFS using these three different diagnostic criteria. METHODS This is a longitudinal study with data originating from a randomized controlled trial conducted between March 2017 and August 2019. A total of 85 malnourished hospitalized patients at risk of RFS according to the National Institute for Health and Clinical Excellence tool for detecting patients at risk of RFS, were included. All patients were provided with enteral tube feeding, and electrolytes were measured daily during the intervention period. Friedli and ASPEN included phosphate, magnesium, and potassium in their definitions, but used different cut-off values. Incidences were recorded, and Kaplan-Meier estimates were used to determine whether mortality was more prevalent in patients with RFS. Regression analysis was used to test for confounders regarding the association between RFS and death, and Kappa was used to test for agreement between the three diagnostic criteria. RESULTS The mean (SD) age of the patients was 79.8 (7.4) years, and the mean (SD) BMI was 18.5 (3.4) kg/m2. The mean (SD) kcal/kg/day was 19 (11) on day one and 26 (15) on day seven. The incidences of RFS differed with the criteria used; 12.9% (TC), 31.8% (Friedli), and 65.9% (ASPEN). Mortality was high, with 36.5% (n = 31) and 56.5% (n = 48) of patients dead at three-month and one-year follow-up, respectively. In the TC, 8/11 (72.7%) with RFS vs. 40/74 (54.1%) without RFS died within one-year, in Friedli 15/27 (55.5%) with RFS vs. 33/58 (56.9%) without RFS died, and in ASPEN 32/56 (65.9%) with RFS, vs. 16/29 (55.2%) without RFS died within one-year. There was no statistically significant difference in mortality between patients with or without RFS regardless of which criteria were used. Age was the only variable associated with death at one-year. The Kappa analysis showed very low agreement between the categories. CONCLUSION Our results show that using different diagnostic criteria significantly impacts incidence rates. However, regardless of criteria used, the mortality was not significantly higher in the group of patients with RFS compared to the patients without RFS. Furthermore, none of the criteria showed a significant association with death at one-year. This supports the need for a global unified diagnostic criterion for RFS. This study was registered in ClinicalTrials.gov (identifier NCT03141489).

Abstract
Micronutrients (MN), i.e. trace elements and vitamins, are essential components of the diet in relatively small amounts in any form of nutrition, with special needs in critically ill patients. Critical illness is characterised by the presence of inflammation and oxidative stress. MNs are tightly involved in antioxidant and immune defences. In addition, some conditions, and treatments result in large losses of biological fluids containing MNs: therefore, acute renal injury requiring renal replacement therapy, acute intestinal failure, and major burns and trauma are at high risk of acute depletion of body stores, and of deficiency. MN requirements are increased above standard DRI. Blood level interpretation is complicated by inflammation: some biomarkers assist the status determination. Due to the acute challenges of critical illness, it of utmost importance to cover the needs to maintain the organism's endogenous immune and antioxidant defences, and capacity to repair tissues. Practical strategies are proposed.

Abstract
Vitamins are essential organic molecules, which are required in the diet in relatively small amounts in any form of nutrition (oral, enteral, parenteral). Despite the small amounts that are required, the vitamins are essential both for maintenance of health, growth, and treatment of disease. After reminding about the principal function of all the vitamins, their needs and the clinical consequences of their deficit, the text present some common clinical problems: the impact of inflammation on the assessment of status. The reasons and diseases which cause increased requirements are presented, with the indications to monitoring of blood levels which remain the classical way to assess status in clinical settings. The text summarises the most relevant clinical manifestations of vitamins depletion and deficiency, the difficulties in assessing status, and makes recommendations for provision for medical nutrition therapy.

Abstract
BACKGROUND Patients receiving parenteral nutrition (PN) may develop refeeding syndrome (RFS). This study determined RFS prevalence in hospitalized adults on PN and evaluated whether higher energy delivered by PN on day 1 of PN initiation was associated with RFS development. METHODS We reviewed the medical records of adult patients receiving PN at a Thai quaternary hospital from June 2019 to May 2022. RFS was defined based on the Nutrition Management Clinical Practice Recommendation by the Society of Parenteral and Enteral Nutrition of Thailand. The association between PN energy delivery and RFS development was determined using a generalized estimating equation for multiple logistic regression analysis adjusted for NICE guideline risk factors. RESULTS A total of 547 patients was included (mean age 59.8 ± 17.2 years, mean body mass index 20.7 ± 4.8 ). The prevalence of RFS was 45%. Factors associated with RFS included energy from PN on the first day of PN initiation (adjusted odds ratio [aOR] 1.17; 95% CI 1.04-1.33; for every 5 kcal/kg/day increase), starvation >5 days prior to PN (aOR 1.54; 95% CI 1.04-2.26), concomitant diuretic use (aOR 1.81; 95% CI 1.25-2.64), low baseline potassium level (aOR 1.79; 95% CI 1.19-2.70), and individual compounding PN (aOR 1.61; 95% CI 1.04-2.51). CONCLUSION RFS was common among hospitalized patients receiving PN. The amount of energy delivered on the first day of PN was independently associated with RFS, raising a concern regarding initiation of PN with higher energy.

Abstract
Refeeding syndrome (RFS) is a potentially life-threatening complication in malnourished (critically ill) patients. The presence of various accepted RFS definitions and the inclusion of heterogeneous patient populations in the literature has led to discrepancies in reported incidence rates in patients requiring treatment at an intensive care unit (ICU). We conducted a prospective observational study from 2010 to 2013 to assess the RFS incidence and clinical characteristics among medical ICU patients at a large tertiary center. RFS was defined as a decrease of more than 0.16 mmol/L serum phosphate to values below 0.65 mmol/L within seven days after the start of medical nutrition therapy or pre-existing serum phosphate levels below 0.65 mmol/L. Overall, 195 medical patients admitted to the ICU were included. RFS was recorded in 92 patients (47.18%). The presence of RFS indicated significantly altered phosphate and potassium levels and was accompanied by significantly more electrolyte substitutions (phosphate, potassium, and magnesium). No differences in fluid balance, energy delivery, and insulin requirements were detected. The presence of RFS had no impact on ICU length of stay and ICU mortality. Screening for RFS using simple diagnostic criteria based on serum phosphate levels identified critically ill patients with an increased demand for electrolyte substitutions. Therefore, stringent monitoring of electrolyte levels is indicated to prevent life-threatening complications.

Abstract
BACKGROUND Trace elements and vitamins, named together micronutrients (MNs), are essential for human metabolism. The importance of MNs in common pathologies is recognized by recent research, with deficiencies significantly impacting the outcome. OBJECTIVE This short version of the guideline aims to provide practical recommendations for clinical practice. METHODS An extensive search of the literature was conducted in the databases Medline, PubMed, Cochrane, Google Scholar, and CINAHL for the initial guideline. The search focused on physiological data, historical evidence (for papers published before PubMed release in 1996), and observational and/or randomized trials. For each MN, the main functions, optimal analytical methods, impact of inflammation, potential toxicity, and provision during enteral or parenteral nutrition were addressed. The SOP wording was applied for strength of recommendations. RESULTS The limited number of interventional trials prevented meta-analysis and led to a low level of evidence for most recommendations. The recommendations underwent a consensus process, which resulted in a percentage of agreement (%): strong consensus required of >90 % of votes. Altogether the guideline proposes 3 general recommendations and specific recommendations for the 26 MNs. Monitoring and management strategies are proposed. CONCLUSION This short version of the MN guideline should facilitate handling of the MNs in at-risk diseases, whilst offering practical advice on MN provision and monitoring during nutritional support.

Abstract
BACKGROUND Patients in the intensive care unit (ICU) are at high risk for refeeding syndrome (RFS), yet there is uncertainty regarding how RFS should be operationalized in the ICU. We evaluated different definitions for RFS and tested how they associated with patient-centered outcomes in the ICU. METHODS This was a retrospective comparison study. Patients age ≥18 years were eligible if they were newly initiated on enteral feeding while hospitalized in the ICU. Eight definitions for RFS were operationalized, including that from the American Society for Parenteral and Enteral Nutrition (ASPEN), all based on electrolyte levels from immediately before until up to 5 days after the initiation of enteral nutrition. Patients were followed for death or for ICU-free days, a measure of healthcare utilization. RESULTS In all, 2123 patients were identified, including 406 (19.1%) who died within 30 days of ICU admission and 1717 (80.9%) who did not. Prevalence of RFS varied from 1.5% to 88% (ASPEN definition) depending on the RFS definition used. The excess risk for death associated with RFS varied from 33% to 92% across definitions. The development of RFS based on the ASPEN definition was associated with a greater decrease in ICU-free days compared with other definitions, but the relationship was not statistically significant. CONCLUSION Eight definitions for RFS were evaluated, none of which showed strong associations with death or ICU-free days. It may be challenging to achieve a standardized definition for RFS that is based on electrolyte values and predicts mortality or ICU-free days.

Crider A, Gillis C, Daniels L, Stern G. Association between dextrose-containing maintenance fluids and phosphorus supplementation during total parenteral nutrition initiation in adult patients who were hospitalized: A retrospective cohort study. JPEN J Parenter Enteral Nutr 2023; 47:1021-1027. [PMID: 37732827 DOI: 10.1002/jpen.2562] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2023] [Revised: 08/22/2023] [Accepted: 09/12/2023] [Indexed: 09/22/2023]
Abstract
BACKGROUND Use of dextrose-containing maintenance fluids prior to parenteral nutrition (PN) initiation is speculated to reduce the risk for refeeding syndrome. We aimed to assess if the use of dextrose vs nondextrose maintenance fluids before PN initiation changes electrolyte supplementation requirements and shifts during initiation. METHODS This retrospective cohort study included patients who received nothing by mouth but received maintenance fluids ≥72 h before PN. The major end point was phosphorus supplementation over 48 h following nutrition initiation. Minor end point included other electrolyte supplementation, changes in electrolyte levels, time to discharge, and goal kilocalories per day. RESULTS Fifty-three patients between August 1, 2019, and August 26, 2020, met criteria for analysis; 60% (n = 32) used a dextrose and 40% (n = 21) used a nondextrose maintenance fluid. Baseline characteristics were similar between fluid groups except for body mass index (25.1 dextrose vs 27.5 kg/m2 nondextrose), sex (43.8% female vs 52.4% male), and severe malnutrition (46.9% vs 28.6%), respectively. Phosphorus (52.5 vs 50 mmol; P = 0.33) and magnesium (24 vs 22 g; P = 0.63) supplementation 48 h following nutrition initiation were similar between groups; however, potassium supplementation was lower in the dextrose group (165.0 vs 208.7 mEq; P = 0.01). No difference was observed between groups for time to discharge following nutrition initiation or time to goal kilocalories per day. After controlling for patients who were malnourished between fluid groups using linear regression, phosphorus repletion differences remained nonsignificant. CONCLUSION This study did not detect a difference in phosphorus supplementation between groups, even after controlling for patients who were malnourished.

Abstract
Refeeding syndrome (RFS) is a serious metabolic disturbance that manifests after reintroducing nutrition to severely malnourished individuals. Especially susceptible are older patients, due to higher malnutrition rates, although the incidence remains uncertain. Our study aimed to assess the occurrence and management of RFS in malnourished older hospitalized patients. This prospective study included 156 malnourished older patients, with malnutrition identified using the Mini Nutritional Assessment-Short Form. We evaluated critical biochemical parameters at admission and for ten days after starting nutritional therapy. Using the consensus evidence-based approach, we managed and evaluated RFS. We also tracked mortality and unexpected hospital readmissions for six months after discharge. The average patient age was 82.3 ± 7.5 years, with 69% female. Patients showed hypophosphatemia (23%), hypomagnesemia (31%), and hypokalemia (6%) on admission. Prior to nutritional replenishment, patients were classified as being at low (64%), high (30%), or very high risk (6%) for RFS. After nutritional therapy, 14% and 5% developed imminent and manifest RFS, respectively. There were no significant differences in six-month post-discharge mortality rates or unexpected hospital readmissions between patients with or without RFS. Despite adherence to guideline-recommended management, RFS can persist. No elevated mortality was noted in RFS patients, potentially due to early diagnosis and treatment.

Abstract
BACKGROUND The refeeding syndrome (RFS) is an oftentimes-unrecognized complication of reintroducing nutrition in malnourished patients that can lead to fatal cardiovascular failure. We hypothesized that a clinical decision support system (CDSS) can improve RFS recognition and management. METHODS We developed an algorithm from current diagnostic criteria for RFS detection, tested the algorithm on a retrospective dataset and combined the final algorithm with therapy and referral recommendations in a knowledge-based CDSS. The CDSS integration into clinical practice was prospectively investigated for six months. RESULTS The utilization of the RFS-CDSS lead to RFS diagnosis in 13 out of 21 detected cases (62%). It improved patient-related care and documentation, e.g., RFS-specific coding (E87.7), increased from once coded in 30 month in the retrospective cohort to four times in six months in the prospective cohort and doubled the rate of nutrition referrals in true positive patients (retrospective referrals in true positive patients 33% vs. prospective referrals in true positive patients 71%). CONCLUSION CDSS-facilitated RFS diagnosis is possible and improves RFS recognition. This effect and its impact on patient-related outcomes needs to be further investigated in a large randomized-controlled trial.

Thiamine pharmaconutrition in sepsis: Monotherapy, combined therapy, or neither? Current evidence on safety and efficacy. Nutrition 2023; 109:112000. [PMID: 36913862 DOI: 10.1016/j.nut.2023.112000] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2022] [Revised: 01/30/2023] [Accepted: 02/04/2023] [Indexed: 02/25/2023]
Abstract
Sepsis is a life-threatening condition characterized by multiorgan dysfunction due to an exaggerated host response to infection associated with a homeostatic failure. In sepsis, different interventions, aimed at improving clinical outcomes, have been tested over the past decades. Among these most recent strategies, intravenous high-dose micronutrients (vitamins and/or trace elements) have been investigated. According to current knowledge, sepsis is characterized by low thiamine levels, which are associated with illness severity, hyperlactatemia, and poor clinical outcomes. However, caution is needed about the clinical interpretation of thiamine blood concentration in critically ill patients, and the inflammatory status, based on C-reactive protein levels, should always be measured. In sepsis, parenteral thiamine has been administered as monotherapy or in combination with vitamin C and corticosteroids. Nevertheless, most of those trials failed to report clinical benefits with high-dose thiamine. The purpose of this review is to summarize the biological properties of thiamine and to examine current knowledge regarding the safety and efficacy of high-dose thiamine as pharmaconutrition strategy when administering singly or in combination with other micronutrients in critically ill adult patients with sepsis or septic shock. Our examination of the most up-to-date evidence concludes that Recommended Daily Allowance supplementation is relatively safe for thiamine-deficient patients. However, current evidence does not support pharmaconutrition with high-dose thiamine as a single therapy or as combination therapy aimed at improving clinical outcomes in critically ill septic patients. The best nutrient combination still needs to be determined, based on the antioxidant micronutrient network and the multiple interactions among different vitamins and trace elements. In addition, a better understanding of the pharmacokinetic and pharmacodynamic profiles of intravenous thiamine is needed. Future well-designed and powered clinical trials are urgently warranted before any specific recommendations can be made regarding supplementation in the critical care setting.

Abstract
BACKGROUND Early nutritional therapy may aggravate hypophosphatemia in critically ill patients. AIM To investigate the influence of the type nutritional therapy on the survival of critically-ill malnourished patients at refeeding hypophosphatemia risk. METHODS Retrospective cohort study including malnourished, critically-ill adults, admitted from June 2014-December 2017 in an intensive care unit (ICU) at a tertiary hospital. Refeeding hypophosphatemia risk was defined as low serum phosphorus levels (<2.5 mg/dL) seen at two timepoints: before the initiation and at day 4 of the nutritional therapy. Patients receiving enteral nutrition (EN) were compared with those receiving supplemental parenteral nutrition (SPN-EN plus parenteral nutrition). Primary outcome was 60 d survival. Secondary endpoint was the incidence of refeeding hypophosphatemia risk. RESULTS We included 468-321 patients (68.6%) received EN and 147 (31.4%) received SPN. The mortality rate was 36.3% (n = 170). Refeeding hypophosphatemia risk was found in 116 (24.8%) patients before and in 177 (37.8%) at day 4 of nutritional therapy. The 60 d mean survival probability was greater for patients receiving SPN both before (42.4 vs. 22.4%, p = 0.005) and at day 4 (37.4 vs. 25.8%, p = 0.014) vs. patients receiving EN at the same timepoints. Cox regression showed a hazard ratio of 3.3 and 2.4 for patients at refeeding hypophosphatemia risk before and at day 4 of EN, respectively, compared to the SPN group at the same timepoints. CONCLUSION Refeeding hypophosphatemia risk was frequent in malnourished ICU patients and the survival for patients receiving SPN seemed associated with better survival than EN only.

Abstract
Assessment of micronutrient (MN) status is of particular importance in patients who require medical nutrition therapy, especially those requiring parenteral nutrition. Blood testing is generally the only tool available in clinical settings to assess MN status. However, using plasma or serum concentration faces pitfalls mainly because of the impact of inflammation that diverts the MNs from the circulating compartment. This review aims to review the blood tests that are useful and provide information about how to integrate functional markers of status to reach a clinically relevant diagnosis. Most impacted, with a significant and proportional decrease in plasma concentrations, are iron, selenium, zinc, thiamin, folic acid, cobalamin, and vitamins A, C, and D; copper is the only MN for which the plasma concentration increases. Therefore, a surrogate marker of inflammation, C-reactive protein, must always be determined simultaneously. Validated intracellular and functional tests are proposed to improve status assessment. A protocol is suggested for tests required both on commencing and during nutrition support. A timely turnaround of analysis is essential for results to be clinically useful. In some cases, the appropriate provision of MNs should be commenced before results have been obtained to confirm the clinical assessment. Laboratory tests of MN status are an area prone to misuse and misinterpretation. The appropriate use and interpretation of such tests are essential to ensure the correct management of nutrition problems.

Abstract
BACKGROUND Until recently, refeeding syndrome (RFS) has lacked standardized diagnostic criteria. This study sought to (1) determine whether RFS, as operationalized in the 2020 American Society for Parenteral and Enteral Nutrition (ASPEN) guideline definition, is associated with adverse clinical outcomes and (2) identify key risk factors for RFS. METHODS In this retrospective cohort study, adults hospitalized from 2015 to 2019 were included if they were ordered for enteral feeding during hospitalization. Data were collected for up to 30 days, and RFS was operationalized as per the ASPEN 2020 guidelines as a ≥10% (corresponding to mild RFS), ≥25% (moderate), and ≥50% (severe) decline in prefeeding serum phosphorus, magnesium, or potassium. The mortality associated with RFS was assessed, and risk factors for RFS were identified using multivariable logistic regression modeling. RESULTS Of 3854 participants, 3480 (90%) developed mild RFS. Thirty-day mortality was higher in those without mild RFS (24%) than in those with mild RFS (18%) (P < 0.01). When RFS was reoperationalized as a 50% decline in electrolytes, 25% of patients developed RFS with a 20% 30-day mortality. Risk factors for development of RFS included renal failure, elevated creatinine, and low platelets; additionally, prefeeding serum phosphorus level was strongly associated with development of RFS (adjusted odds ratio, 6.09; 95% confidence interval, 4.95-7.49 for those in the highest tertile of prefeeding phosphorus compared with the lowest). CONCLUSION The ASPEN operationalization of RFS as a decline in baseline electrolyte values was not associated with death. Prefeeding serum phosphorus level strongly predicted severe RFS.

Abstract
BACKGROUND & AIMS Hypophosphatemia during critical illness has been associated with adverse outcome. The reintroduction of enteral or parenteral nutrition, leading to refeeding hypophosphatemia (RFH), has been presented as potential risk factor. We investigated the occurrence of early RFH, its association with clinical outcome, and the impact of early parenteral nutrition (PN) on the development of early RFH in pediatric critical illness. METHODS This is a secondary analysis of the PEPaNIC randomized controlled trial (N = 1440), which showed that withholding supplemental parenteral nutrition (PN) for 1 week (late-PN) in the pediatric intensive care unit (PICU) accelerated recovery and reduced new infections compared to early-PN (<24 h). Patients with renal replacement therapy or unavailable phosphate concentrations were excluded from this analysis. Early RFH was defined as serum/plasma phosphate <0.65 mmol/L and a drop of >0.16 mmol/L within 3 days of admission to the PICU. The association between baseline characteristics and early RFH, and the association of early RFH with clinical outcome were investigated using logistic and linear regression models, both uncorrected and corrected for possible confounders. To examine the impact of nutritional intake on phosphate concentrations, structural nested mean models with propensity score and censoring models were used. RESULTS A total of 1247 patients were eligible (618 early-PN, 629 late-PN). Early RFH occurred in 40 patients (3%) in total, significantly more in the early-PN group (n = 31, within-group occurrence 5%) than in the late-PN-group (n = 9, within-group occurrence 1%, p < 0.001). Patients who were older (OR 1.14 (95% CI 1.08; 1.21) per year added, p < 0.001) and who had a higher Pediatric Risk of Mortality (PIM3) score had a higher risk of developing early RFH (OR 1.36 (95% CI 1.15; 1.59) per unit added, p < 0.001), whereas patients in the late-PN group had a lower risk of early RFH (OR 0.24 (95% CI 0.10; 0.49), p < 0.001). Early RFH was significantly associated with a 56% longer PICU stay (p = 0.003) and 42% longer hospital stay (p = 0.007), but not with new infections (OR 2.01 (95% CI 0.90; 4.30), p = 0.08) or length of mechanical ventilatory support (OR 1.05 (95% CI -3.92; 6.03), p = 0.68), when adjusted for possible confounders. Increase of parenteral nutrition intake (in % kcal of predicted resting energy expenditure) decreased phosphate concentrations (c = -0.002 (95% CI -0.002; -0.001). CONCLUSIONS Early RFH occurred in 3% of critically ill children. Patients randomized to late-PN had a lower chance of developing early RFH, which may be explained by the more gradual build-up of nutrition. As early RFH might impact recovery, it is important to closely monitor phosphate concentrations in patients, especially of those at risk for early RFH.

Abstract
Malnutrition is one of the most frequent metabolic challenges in the population of chronically ill patients. This results in increased administration of nutritional therapy in inpatient settings, which poses the risk of side effects, in particular, the development of refeeding syndrome. If not managed accordingly, it leads to a significant rise in morbidity and mortality. However, despite its importance, evidence-based recommendations on the management of refeeding syndrome are largely lacking, and only a few randomized controlled trials have been conducted. In light of this, the aim of this review is to raise awareness of refeeding syndrome in chronically ill patients by critically reviewing recent literature and providing a short overview as well as diagnosis and treatment algorithms of this underreported metabolic condition. In summary, recent findings suggest undergoing risk assessment and stratification for every patient receiving nutritional therapy. According to this, adaptation of energy and fluid support during the replenishment phase should be implemented in the nutritional therapy for patients at high risk. Additionally, continuous monitoring should take place, and appropriate actions should be initiated when necessary.

Abstract
BACKGROUND Trace elements and vitamins, named together micronutrients (MNs), are essential for human metabolism. Recent research has shown the importance of MNs in common pathologies, with significant deficiencies impacting the outcome. OBJECTIVE This guideline aims to provide information for daily clinical nutrition practice regarding assessment of MN status, monitoring, and prescription. It proposes a consensus terminology, since many words are used imprecisely, resulting in confusion. This is particularly true for the words "deficiency", "repletion", "complement", and "supplement". METHODS The expert group attempted to apply the 2015 standard operating procedures (SOP) for ESPEN which focuses on disease. However, this approach could not be applied due to the multiple diseases requiring clinical nutrition resulting in one text for each MN, rather than for diseases. An extensive search of the literature was conducted in the databases Medline, PubMed, Cochrane, Google Scholar, and CINAHL. The search focused on physiological data, historical evidence (published before PubMed release in 1996), and observational and/or randomized trials. For each MN, the main functions, optimal analytical methods, impact of inflammation, potential toxicity, and provision during enteral or parenteral nutrition were addressed. The SOP wording was applied for strength of recommendations. RESULTS There was a limited number of interventional trials, preventing meta-analysis and leading to a low level of evidence. The recommendations underwent a consensus process, which resulted in a percentage of agreement (%): strong consensus required of >90% of votes. Altogether the guideline proposes sets of recommendations for 26 MNs, resulting in 170 single recommendations. Critical MNs were identified with deficiencies being present in numerous acute and chronic diseases. Monitoring and management strategies are proposed. CONCLUSION This guideline should enable addressing suboptimal and deficient status of a bundle of MNs in at-risk diseases. In particular, it offers practical advice on MN provision and monitoring during nutritional support.

Abstract
Refeeding Syndrome: Where Do We Stand in 2022? Abstract. The refeeding syndrome is a potentially life-threatening condition that can occur when refeeding malnourished patients. In recent years, two consensus manuscripts were published by the major clinical nutrition societies ESPEN and ASPEN. Pathophysiological aspects, clinical manifestations, prevention measures and criteria for diagnosis and management have been described in detail. The aim of this mini-review is to provide an evidence-based overview on the refeeding syndrome. For this purpose, the systematic literature search by Friedli et al. 2015 was updated. Evidence that the refeeding syndrome is associated with a negative clinical outcome exists. Many questions about management aspects remain unanswered. A robust randomized controlled trial is urgently needed to answer all these questions in an evidence-based manner and to elicit reliable evidence about independent predictors and an estimate of metabolic risk.

Abstract
Disease-related malnutrition in adult patients who have been admitted to hospital is a syndrome associated with substantially increased morbidity, disability, short-term and long-term mortality, impaired recovery from illness, and cost of care. There is uncertainty regarding optimal diagnostic criteria, definitions for malnutrition, and how to identify patients who would benefit from nutritional intervention. Malnutrition has become the focus of research aimed at translating current knowledge of its pathophysiology into improved diagnosis and treatment. Researchers are particularly interested in developing nutritional interventions that reverse the negative effects of disease-related malnutrition in the hospital setting. High-quality randomised trials have provided evidence that nutritional therapy can reduce morbidity and other complications associated with malnutrition in some patients. Screening of patients for risk of malnutrition at hospital admission, followed by nutritional assessment and individualised nutritional interventions for malnourished patients, should become part of routine clinical care and multimodal treatment in hospitals worldwide.

Abstract
BACKGROUND & AIMS Refeeding syndrome (RFS) is a disease that occurs when feeding is restarted and metabolism changes from catabolic to anabolic status. RFS can manifest variously, ranging from asymptomatic to fatal, therefore it may easily be overlooked. RFS prediction using explainable machine learning can improve diagnosis and treatment. Our study aimed to propose a machine learning model for RFS prediction, specifically refeeding hypophosphatemia, to evaluate its performance compared with conventional regression models, and to explain the machine learning classification through Shapley additive explanations (SHAP) values. METHODS A retrospective study was conducted including 806 patients, with 2 or more days of nothing-by-mouth prescription, and with phosphate (P) level measurements within 5 days of refeeding were selected. We divided the patients into hypophosphatemia (n = 367) and non-hypophosphatemia groups (n = 439) at a P level of 0.8 mmol/L. Among the features examined within 48 h after admission, we reviewed laboratory test results and electronic medical records. Logistic, Lasso, and ridge regressions were used as conventional models, and performances were compared with our extreme gradient boosting (XGBoost) machine learning model using the area under the receiver operating characteristic curve. Our model was explained using the SHAP value. RESULTS The areas under the curve were 0.950 (95% confidence interval: 0.924-0.975) for our XGBoost machine learning model and surpassed the performance of conventional regression models; 0.760 (0.707-0.813) for logistic regression, 0.751 (0.694-0.807) for Lasso regression, and 0.758 (0.701-0.809) for ridge regression. According to the SHAP values in the order of importance, low initial P, recent weight loss, high creatinine, diabetes mellitus with insulin use, low haemoglobin A1c, furosemide use, intensive care unit admission, blood urea nitrogen level of 19-65, parenteral nutrition, magnesium below or above the normal range, low potassium, and older age were features to predict refeeding hypophosphatemia. CONCLUSIONS The machine learning model for predicting RFS has a substantially higher effectiveness than conventional regression methods. Creating an accurate risk assessment tool based on machine learning for early identification of patients at risk for RFS can enable careful nutrition management planning and monitoring in the intensive care unit, towards reducing the incidence of RFS-related morbidity and mortality.

Abstract
Zusammenfassung
Hintergrund Das Refeeding-Syndrom (RFS) ist eine Stoffwechselreaktion verursacht durch eine inadäquate Wiederernährung nach einer Hungerphase. Das RFS ist gekennzeichnet durch eine Serumelektrolyt- und Flüssigkeitsverschiebung, welche schwerwiegende Folgen wie Herzrhythmusstörungen verursachen können und gelegentlich zum Tod führen. Zur Prävention sind eine frühzeitige Risikoerkennung sowie ein angepasstes Ernährungsmanagement notwendig. Verschiedene Studien weisen auf ein unzureichendes Wissen der Ärzteschaft hin. Für die Schweiz existieren zum heutigen Zeitpunkt keine Daten. Mit dieser Studie wurde der Wissensstand der Humanmedizinstudierenden der Deutschschweiz im letzten Semester zum RFS untersucht.
Material und Methodik Das Wissen wurde mittels Onlinefragebogen erfasst. Dieser enthielt 15 Multiple-Choice-Fragen. Die maximal mögliche Gesamtpunktzahl betrug 20 Punkte. Die Ergebnisse wurden gemäß Schweizer Notenberechnung beurteilt (beste Note 6, schlechteste Note 1). 60 % der Punkte mussten erreicht werden, um ein genügendes Ergebnis (Note 4) zu erreichen.
Ergebnisse 79 von 540 Studierenden beantworteten den Fragebogen, was einer Rücklaufquote von 14,6 % entspricht. Die Studierenden erreichten durchschnittlich 9,9 Punkte (50 % der Gesamtpunktzahl). Das Resultat von 53 % der Studierenden war ungenügend. Neun von 79 Studierenden (11,4 %) war das RFS unbekannt.
Schlussfolgerung Das Wissen der Schweizer Humanmedizinstudierenden zum RFS ist nicht zufriedenstellend und sollte unbedingt optimiert werden. In stationären Einrichtungen ist ein flächendeckendes Ernährungsscreening mit einem validierten Instrument empfohlen. Risikopatienten für eine Mangelernährung sollten an eine Ernährungsberatung (ERB) überwiesen werden. Die ERB erkennt im Ernährungsassessment das Risiko für ein RFS und kann in Zusammenarbeit mit der behandelnden Ärzteschaft den Ernährungsaufbau planen. Eine gute multiprofessionelle Zusammenarbeit ist unerlässlich, um Komplikationen zu verhindern.

Abstract
BACKGROUND The refeeding syndrome has been described as a potentially life-threatening complication of renutrition. However, moving from single reports to larger population studies, the real impact of refeeding syndrome on all-cause mortality is still unknown. METHODS PubMed/Medline, EMBASE, Cochrane library, and CINAHL databases were systematically searched until September 2020 for studies reporting mortality rates in patients who developed the syndrome at renutrition compared with those who did not develop it. Effect sizes were pooled through a random-effect model. RESULTS Thirteen studies were finally considered in the meta-analysis, for a total of 3846 patients (mean age 64.5 years; 58% males). Pooled data showed a nonsignificant trend toward an increased short-term (≤1 month) mortality in patients developing the refeeding syndrome (odds ratio = 1.27, 95% confidence interval 0.93-1.72), mostly driven by studies in which renutrition was not prescribed and supervised by a nutritional support team (P = .01 at subgroup analysis) and by studies published in previous years (P = .04 at meta-regression). When examining medium-term (≤6 month) mortality, an overall statistical significance toward higher risk was observed (odds ratio = 1.54, 95% confidence interval 1.04-2.28). CONCLUSION This was the first meta-analysis that specifically assessed the impact of refeeding syndrome on mortality. Our results suggested a nonsignificant trend toward increased mortality in the short term but a significantly increased mortality in the medium term. The supervision/management of the refeeding process by a nutrition specialist might be a key factor for the limitation of this mortality excess.

Abstract
INTRODUCTION Refeeding syndrome (RFS) is a metabolic complication in the initial phase of nutritional therapy (NT). Studies evaluating electrolyte abnormalities among patients at risk for RFS undergoing NT in the Emergency Department (ED) are scarce. OBJECTIVE to explore the occurrence of electrolyte abnormalities among patients at risk for RFS with enteral nutrition admitted to the ED. MATERIAL AND METHODS a retrospective cohort study that evaluated 440 adult patients undergoing NT, admitted to the ED of a public tertiary teaching hospital regarding RFS risk. Additional eligibility criteria included nutritional assessment by registered dietitians and at least one dose of an electrolyte (sodium, potassium, magnesium, phosphate, calcium) ordered by physicians. Differences were considered statistically significant at p < 0.05. RESULTS RFS risk criteria identified 83 (18.9 %) (65.1 % elderly, aged 64.2 ± 11.6 years, 65.1 % male; body mass index, 17.3 ± 3.5 kg/m²) patients at risk, of which 25 (30.1 %) received phosphorus, 48 (57.8 %) magnesium, and 60 (72.3 %) calcium doses within the first week. All patients at risk for RFS had potassium and sodium evaluations. Hypophosphatemia was identified in 10 (40.0 %), hypomagnesemia in 12 (25.0 %) and hypokalemia in 13 (15.7 %) patients. Almost half of phosphorus assessments resulted from advice by registered dietitians to the staff. CONCLUSION electrolyte evaluation was not ordered in all at-risk patients on NT. Despite the small sample, hypophosphatemia was a very common condition among this group. This study highlights the importance of RFS risk screening awareness among NT patients, and the important role of registered dietitians in this context. Larger sample studies are needed to confirm these results.

Abstract
INTRODUCTION Refeeding syndrome occurs with the reintroduction of food after an individual has undergone a substantial period of malnutrition. The development of this condition is not uncommon but is neglected in most cases. OBJECTIVE To identify the incidence of refeeding syndrome in hospitalized patients undergoing total parenteral nutrition and factors that may be associated with this condition. MATERIALS AND METHODS Observational retrospective and prospective cohort study. Data collection took place at the Hospital de Clínicas de Porto Alegre, from 2015 to 2018. Data was collected consecutively from patient electronic medical records. All hospitalized individuals aged 18 years or more and having a prescription for total parenteral nutrition were included in the study. Exclusion criteria included patients with diabetic ketoacidosis; receiving renal replacement therapy or chronic kidney disease with a glomerular filtration rate <30 mL/min; severe metabolic acidosis or any disease that could affect serum phosphorus levels. WinPepi software, version 11.65, was used to calculate sample size. Data analysis was performed using SPSS version 20.0. A 5% significance level was considered for the established comparisons. The project was approved by the Research Ethics Committee of Hospital de Clínicas de Porto Alegre (number 17-0313). RESULTS Data from 97 patients was collected. The incidence of refeeding syndrome in our sample was 43.3% (n = 42). Factors positively associated with the syndrome were use of standard parenteral nutrition (p < 0.01), advancing age (mean 62.8 yr versus 55.1 yr; p = 0.013), and amount of total energy administered, which were 25.6 kcal/kg/day versus 23.6 kcal/kg/day for patients with and without refeeding syndrome, respectively (p < 0.01). CONCLUSION The incidence of refeeding syndrome in individuals using total parenteral nutrition was high. The supply of a greater quantity of total energy in the first week of nutritional therapy, the absence of electrolytes in the parenteral nutrition solution and advancing age were all factors associated with the emergence of refeeding syndrome.

Abstract
BACKGROUND & AIMS The refeeding syndrome (RFS) has been recognized as a potentially life-threatening metabolic complication of re-nutrition, but the definition widely varies and, its incidence is unknown. The aim of this systematic review and meta-analyses was to estimate the incidence of RFS in adults by considering the definition used by the authors as well as the recent criteria proposed by the American Society of Parenteral and Enteral Nutrition (ASPEN) consensus. Furthermore, the incidence of refeeding hypophosphatemia (RH) was also assessed. METHODS Four databases were systematically searched until September 2020 for retrieving trials and observational studies. The incidences of RFS and RH were expressed as percentage and reported with 95% confidence intervals (CI). RESULTS Thirty-five observational studies were included in the analysis. The risk of bias was serious in 16 studies and moderate in the remaining 19. The incidence of RFS varied from 0% to 62% across the studies. No substantial change in the originally reported incidence of RFS was found by applying the ASPEN criteria. Similarly, the incidence of RH ranged between 7% and 62%. In the subgroup analyses, inpatients from Intensive Care Units (ICUs) and those initially fed with >20 kcal/kg/day seemed to have a higher incidence of both RFS (pooled incidence = 44%; 95% CI 36%-52%) and RH (pooled incidence = 27%; 95% CI 21%-34%). However, due to the high heterogeneity of data, summary incidence measures are meaningless. CONCLUSION The incidence rate of both RFS and RH greatly varied according to the definition used and the population analyzed, being higher in ICU inpatients and in those with increased initial caloric supply. Therefore, a universally accepted definition for RFS, taking different clinical contexts and groups of patients into account, is still needed to better characterize the syndrome and its approach.

The impact of nutritional support on malnourished inpatients with aging-related vulnerability. Nutrition 2021; 89:111279. [PMID: 34090212 DOI: 10.1016/j.nut.2021.111279] [Citation(s) in RCA: 20] [Impact Index Per Article: 6.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2021] [Revised: 03/04/2021] [Accepted: 04/01/2021] [Indexed: 11/22/2022]
Abstract
OBJECTIVES Malnutrition is highly prevalent in patients with aging-related vulnerability defined by very old age (≥80 y), physical frailty or cognitive impairment, and increases the risks for morbidity and mortality. The effects of individualized nutritional support for patients with aging-related vulnerability in the acute hospital setting on mortality and other clinical outcomes remains understudied. METHODS For this secondary analysis of the randomized-controlled Effect of Early Nutritional Support on Frailty, Functional Outcomes, and Recovery of Malnourished Medical Inpatients Trial (EFFORT), we analyzed data of patients at a nutritional risk (Nutritional Risk Screening 2002 score ≥3 points) with aging-related vulnerability, randomized to receive protocol-guided individualized nutritional support to reach specific protein and energy goals (intervention group) or routine hospital food (control group). The primary endpoint was all-cause 30-d mortality. RESULTS Of the 881 patients with aging-related vulnerability, 23.4% presented with a frailty syndrome, 81.8% were age ≥80 y and 15.3% showed cognitive impairment. Patients with aging-related vulnerability receiving individualized nutritional support compared with routine hospital food showed a >50% reduction in the risk of 30-day mortality (60 of 442 [13.6%] versus 31 of 439 [7.1%]; odds ratio: 0.48; 95% confidence interval, 0.31-0.76; P = 0.002). Significant improvements were also found for long-term mortality at 180 days, as well as functional outcomes and quality of life measures. CONCLUSIONS Malnourished patients with aging-related vulnerability show a significant and clinically relevant reduction in the risk of mortality and other adverse clinical outcomes after individualized in-hospital nutritional support compared to routine hospital nutrition. These data support the early screening of patients with aging-related vulnerability for nutritional risk, followed by a nutritional assessment and implementation of individualized nutritional interventions.

Nutritional risk is a predictor for long-term mortality: 5-Year follow-up of the EFFORT trial. Clin Nutr 2021; 40:1546-1554. [PMID: 33743290 DOI: 10.1016/j.clnu.2021.02.032] [Citation(s) in RCA: 22] [Impact Index Per Article: 7.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2020] [Revised: 01/28/2021] [Accepted: 02/18/2021] [Indexed: 01/04/2023]
Abstract
BACKGROUND AND AIMS The nutritional risk screening (NRS 2002) is a validated screening tool for malnutrition. This study aims to investigate the prognostic value of the NRS 2002 and its individual components regarding long-term mortality and adverse outcomes in a well-characterized cohort of medical inpatients. METHODS We performed a 5-year follow-up investigation of patients included in the investigator-initiated, prospective, randomized controlled multicenter EFFORT trial that evaluated the effects of individualized nutritional intervention vs. standard hospital food. We used multivariable cox regression analyses adjusted for randomisation arm, study centre, comorbidities and main admission diagnosis to investigate associations between NRS 2002 total scores at time of hospital admission and several long-term outcomes. RESULTS We had confirmed mortality data over the mean follow-up time of 3.2 years in 1874 from the initial cohort of 2028 EFFORT patients. Mortality showed a step-wise increase in patients with NRS 3 (289/565 [51.2%]) and NRS 4 (355/717 [49.6%]) to 59.5% (353/593) in patient with NRS≥5 corresponding to an adjusted Hazard Ratio (HR) of 1.28 (95%CI 1.15 to 1.42, p ≤ 0.001) for mortality after one year and 1.13 (95%CI 1.05 to 1.23, p = 0.002) for the overall time period. All individual components of NRS including disease severity, food intake, weight loss and BMI provided prognostic information regarding long-term mortality risk. CONCLUSION Nutritional risk mirrored by a NRS 2002 total score is a strong and independent predictor of long-term mortality and morbidity in polymorbid medical inpatients particularly in patients with high nutritional risk with an NRS ≥5 points.

Abstract
BACKGROUND Patients with chronic kidney disease (CKD) are at substantial risk of malnutrition, which negatively affects clinical outcomes. We investigated the association of kidney function assessed at hospital admission and effectiveness of nutritional support in hospitalized medical patients at risk of malnutrition. METHODS This is a secondary analysis of an investigator-initiated, randomized-controlled, Swiss multicenter trial (EFFORT) that compared individualised nutritional support with usual hospital food on clinical outcomes. We compared effects of nutritional support on mortality in subgroups of patients stratified according to kidney function at the time of hospital admission (estimated glomerular filtration rates [eGFR] <15, 15-29, 30-59, 60-89 and ≥ 90 ml/min/1.73 m2). RESULTS We included 1943 of 2028 patients (96%) from the original trial with known admission creatinine levels. Admission eGFR was a strong predictor for the beneficial effects of nutritional support in regard to lowering of 30-day mortality. Patients with an eGFR <15, 15-29 and 30-59 had the strongest mortality benefit (odds ratios [95%CI] of 0.24 [0.05 to 1.25], 0.37 [0.14 to 0.95] and 0.39 [0.21 to 0.75], respectively), while patients with less severe impairment in kidney function had a less pronounced mortality benefits (p for interaction 0.001). A similar stepwise association of kidney function and response to nutritional support was found also for other secondary outcomes. CONCLUSION In medical inpatients at nutritional risk, admission kidney function was a strong predictor for the response to nutritional therapy. Initial kidney function may help to individualize nutritional support in the future by identification of patients with most clinical benefit.

Abstract
Refeeding syndrome can occur in malnourished patients with acute pancreatitis who have electrolyte imbalances. Refeeding syndrome is characterized by severe electrolyte imbalances (mainly hypophosphatemia, hypomagnesemia, and hypokalemia), vitamin deficiency (mainly thiamine deficiency), fluid overload, and salt retention resulting in organ dysfunction and cardiac arrhythmias. We herein report a case involving a patient with severe pancreatitis and gallbladder stones who developed refeeding syndrome with shock and loss of consciousness. The patient was treated by opportune vitamin and electrolyte supplementation therapy and showed substantial improvement after 2 weeks of hospitalization, gaining the ability to eat small bites of solid food orally. Early diagnosis and treatment of refeeding syndrome may reduce morbidity and mortality in patients with acute pancreatitis. Patients should be fasted only if alimentation is contraindicated, and electrolyte values must be closely monitored.

Abstract
BACKGROUND & AIMS Hypophosphatemia (HypoP) is associated with organ dysfunction and mortality. Despite its potential severe consequences, HypoP remains poorly characterized in terms of real prevalence and timing of onset. The primary objective was to determine the prevalence of HypoP defined as blood phosphate <0.8 and < 0.65 mmol/l on one particular day at international level. METHODS One-day point prevalence survey conducted by the Section of Metabolism, Endocrinology and Nutrition (MEN) of the European Society of Intensive Care Medicine (ESICM) during week 11-2020. RESULTS In total, 56 adult and 4 paediatric ICUs, from 22 countries participated: 41 ICUs were mixed medico surgical, the 19 others being cardiac, medical or surgical. Phosphate measurements were performed daily in 21 ICUs, and 1-3 times per week in 39 ICUs. On D-Day 909 patients (883 adults) were present and 668/883 (75.7%) had serum/plasma phosphate determined, revealing a HypoP in 103 (15.4%) patients aged 62 [18 to 85] years. Of those, 49 patients presented phosphate <0.65 mmol/l: cases of hypophosphatemia were detected at any time of patient's ICU stay. No HypoP was observed in children. A treatment protocol existed only in 41.1% of adult ICUs, independently of ICU type, or size. Only 41/98 of the HypoP patients (29/41 of patients with phosphate <0.65 mmol/l) were receiving phosphate. CONCLUSION HypoP is present at least in 15.4% of ICU patients, and may occur at any time during the ICU stay. The absence of phosphate repletion protocols in 60% of participating ICUs is an unexpected finding, and confirms the necessity for the development of ICU phosphate protocols and guidelines.

Abstract
BACKGROUND/AIMS Refeeding syndrome can result following excessive feeding of malnourished patients. The syndrome remains poorly defined but encompasses a range of adverse effects including electrolyte shifts, hyperglycaemia and other less well-defined phenomena. There are additional risks of underfeeding malnourished individuals. Studies of refeeding syndrome have generally focussed on critical care environments or patients with anorexia nervosa. Here we have conducted a two-centre, prospective, double-blind, randomised controlled trial amongst all patients referred to hospital nutrition support teams for intravenous nutrition support. We sought to determine whether electrolyte and other abnormalities suggestive of refeeding syndrome risk varied depending on initial rate of intravenous feeding. METHODS Patients at moderate or high risk of refeeding syndrome, as defined by United Kingdom National Institute of Health and Care Excellence guidelines, were screened for inclusion. Patients were randomised to receive either high (30 kcal/kg/day, 0.25 gN/kg/day) or low (15 kcal/day, 0.125 gN/kg/day) rate feeding for the first 48 h prior to escalation to standard parenteral nutrition regimens. The primary outcome was rates of potential refeeding risks within the first 7 days as defined by electrolyte imbalance or hyperglycaemia requiring insulin. Secondary outcomes included effects on QTc interval, infections and length of hospital stay. Statistical analysis was performed with χ2 or Wilcoxon rank sum tests and all analysis was intention-to-treat. Problems with study recruitment led to premature termination of the trial. Registered on the EU Clinical Trials Register (EudraCT number 2007-005547-17). RESULTS 534 patients were screened and 104 randomised to either high or low rate feeding based on risk of refeeding syndrome. Seven patients were withdrawn prior to collection of baseline demographics and were excluded from analysis. 48 patients were analysed for the primary outcome with potential refeeding risks identified in 46%. No differences in risks were seen between high and low rate feeding (p > 0.99) or high and moderate risk feeding (p = 0.68). There were no differences in QTc abnormalities, infection rates, or hospital length of stay between groups. CONCLUSIONS In this randomised trial of rates of refeeding risk, in patients pre-stratified as being at high or moderate risk, we found no evidence of increased refeeding related disturbances in those commenced on high rate feeding compared to low rate. No differences were seen in secondary endpoints including cardiac rhythm analysis, infections or length of stay. Our study reflects real world experience of patients referred for nutrition support and highlights challenges encountered when conducting clinical nutrition research.

Abstract
Rheumatische Krankheiten können über verschiedene Mechanismen zu einer Mangelernährung, also einer nicht ausreichenden Deckung des Bedarfs an Energie, Proteinen, Elektrolyten oder anderen Nährstoffen, führen. Bei Wiederbeginn mit vollwertiger Ernährung nach einer Phase einer solchen katabolen Stoffwechsellage kommt es zu metabolischen Veränderungen, die in einen akuten Mangel an verfügbaren Elektrolyten und anderen Mikronährstoffen führen und dann lebensbedrohliche Komplikationen auslösen können. Das Auftreten solcher Komplikationen nach Wiederbeginn der Ernährung wird als Refeeding-Syndrom bezeichnet. Mit Wissen um diese Komplikationen, dem adäquaten Wiederbeginn der Ernährung und ggf. einer Überwachung der relevanten Parameter sowie gezielter Supplementierung kann das Refeeding-Syndrom vermieden werden. In dieser Übersichtsarbeit werden die Pathomechanismen des Refeeding-Syndroms erklärt, die Risikofaktoren für das Auftreten des Refeeding-Syndroms – insbesondere unter Betrachtung von rheumatologischen Patienten – identifiziert und die nötige Therapie zur Vermeidung eines Refeeding-Syndroms bei Wiederbeginn der Ernährung dargestellt.

Abstract
AIM OF THE STUDY Hepatic changes have been described during the refeeding syndrome due to increase in enzymes and hepatomegaly; however, they have not been properly described. Thus, the objective of this study was to investigate the hepatic histological characteristics and biochemical markers of hepatic steatosis in Wistar rats with refeeding syndrome. MATERIAL AND METHODS Thirty male Wistar rats were allocated to one of three groups: C, F or R. The animals from group C received an AIN-93 diet for 96 hours, and were then sacrificed. Animals allocated to group F were fasted for 48 hours and sacrificed. Animals from group R were also fasted for 48 hours, but were refed for another 48 hours, with AIN-93. The liver, blood and epididymal and retroperitoneal fats were collected. RESULTS Data obtained in groups F and R show the changes observed in refeeding syndrome, during starvation and refeeding. The serum glucose, magnesium, potassium and phosphorus, in group F, decreased. There was no evidence of hepatic steatosis. Hypophosphatemia, hypomagnesemia and hypokalemia were also observed in group R, confirming refeeding syndrome. The main histological characteristic, in this group, was the extensive presence of ballooning degeneration. This is the first article that has detected such change in liver structure, due to refeeding syndrome. The possible causes are: retention of sodium, causing whole body edema; and/or dysfunction of the sodium/potassium pump of the hepatocytes, as a result of hypophosphatemia. CONCLUSIONS This is the first description of an animal model of hepatic severe ballooning degeneration induced due to refeeding syndrome.

Mortality associated with new risk classification of developing refeeding syndrome in critically ill patients: A cohort study. Clin Nutr 2020; 40:1207-1213.

Abstract
BACKGROUND & AIMS Although refeeding syndrome (RFS) has been recognized as a potentially fatal metabolic complication, the definition of RFS has remained unclear. Recently, European researchers suggested an evidence-based and consensus-supported algorithm that consisted of a new RFS risk classification and treatment strategies for medical inpatients. The classification was based on the National Institute for Health and Clinical Excellence (NICE) criteria for patients at risk of developing RFS. In this study, we aimed to investigate the frequency of each applied new risk group and the association between the new classification and mortality in critically ill patients. METHODS This cohort study was conducted at a Japanese metropolitan tertiary-care university hospital from December 2016 to December 2018. We included critically ill adult patients who were admitted to the intensive care unit (ICU) via the emergency department and who stayed in the ICU for 24 h or longer. We applied the new risk classification based on the NICE RFS risk factors on ICU admission. The main exposure was risk classification of RFS: no risk, low risk, high risk, or very high risk. The primary outcome was in-hospital mortality censored at day 30 after ICU admission. We performed a multivariable analysis using Cox proportional hazard regression. RESULTS We analyzed 542 patients who met the eligibility criteria. The prevalence of the four RFS risk classification groups was 25.8% for no risk, 25.7% for low risk, 46.5% for high risk, and 2.0% for very high risk. The 30-day mortality was 5.0%, 7.2%, 16.3%, and 27.3%, respectively (log-rank trend test: p < 0.001). In the multivariable Cox regression, adjusted hazard ratios with no risk group as a reference were 1.28 (95% CI 0.48-3.38) for low risk, 2.81 (95% CI 1.24-6.35) for high risk, and 3.17 (95% CI 0.78-12.91) for very high risk. CONCLUSIONS Approximately half the critically ill patients were categorized as high or very high risk based on the new risk classification. Furthermore, as the risk categories progressed, the 30-day in-hospital mortality increased. Early recognition of patients at risk of developing RFS may improve patient outcomes through timely and optimal nutritional treatment.

Abstract
BACKGROUND/OBJECTIVES Refeeding syndrome (RFS) can occur in severely malnourished or starved populations that are provided with rapid or unbalanced nutrition. International guidelines recommend a cautious approach for managing RFS risk (hypocaloric nutrition for 4-7 days), however emerging evidence supports a more assertive approach. This study aimed to describe nutritional management and RFS-related adverse outcomes in patients at risk of RFS receiving care after implementing updated guidelines reflecting emerging evidence. SUBJECTS/METHODS A retrospective cohort study of inpatients at risk of RFS during admission to a large metropolitan hospital in Queensland, Australia between November 2018 and April 2019 was conducted. Data were collected from medical records on nutritional management (provision of nutrition, electrolyte, and vitamin replacement) and outcomes (incidence of RFS, serum electrolyte decreases, hypo/hyperglycaemia, oedema, and organ function disturbance). Data were analysed descriptively; relationships between serum electrolyte decreases and nutrition management were explored using Fisher's Exact tests. RESULTS Of the 70 patients identified at risk of RFS (58.4 ± 16.8 years, 56% male, 94% malnourished), majority of participants received required supplementation prior to the commencement of nutrition (thiamine: 76%; micronutrients: 72-100%; multivitamin: 61%) and a standard initial nutrition management plan (79%; cautious: 13%; liberal: 8%). There were no cases of RFS. Four participants experienced RFS-related adverse outcomes (severe electrolyte decreases: n = 2, hypo/hyperglycaemia: n = 2); however, there was no differences in serum electrolyte decreases based on the nutrition management plan (initial: p = 0.912; goal: p = 0.688). CONCLUSIONS The implementation of more liberal RFS guidelines for the management of RFS risk appears to be safe. Further research examining liberalised refeeding protocols may be useful in updating international guidelines.

Abstract
Refeeding syndrome (RFS) is the metabolic response to the switch from starvation to a fed state in the initial phase of nutritional therapy in patients who are severely malnourished or metabolically stressed due to severe illness. It is characterized by increased serum glucose, electrolyte disturbances (particularly hypophosphatemia, hypokalemia, and hypomagnesemia), vitamin depletion (especially vitamin B1 thiamine), fluid imbalance, and salt retention, with resulting impaired organ function and cardiac arrhythmias. The awareness of the medical and nursing staff is often too low in clinical practice, leading to under-diagnosis of this complication, which often has an unspecific clinical presentation. This review provides important insights into the RFS, practical recommendations for the management of RFS in the medical inpatient population (excluding eating disorders) based on consensus opinion and on current evidence from clinical studies, including risk stratification, prevention, diagnosis, and management and monitoring of nutritional and fluid therapy.
