ZusammenfassungDie klinische Praxis der Ernährungstherapie auf Intensivstationen, eine anerkannte Unterstützung von Patient*innen, die nicht selbst ausreichend essen können, basiert auf teils divergierenden Leitlinien und randomisierten Studien, die unterschiedliche Vorgangsweisen zum Standard erhoben. Zweck der aktuellen Analyse von Daten des nutritionDay-Projekts ist es, die derzeit weltweite klinische Praxis mit jener in Europa sowie in der Region Deutschland, Österreich und Schweiz (DACH) zu vergleichen. Zwischen den Jahren 2007 und 2021 wurden Daten von 18.918 Patient*innen, die in 1595 Intensivstationen aufgenommen waren, in einer Querschnittsuntersuchung online erfasst. Die Untersuchung verfolgt das Ziel, alle an einem Tag anwesenden Patient*innen zu erfassen. Die mediane Aufenthaltsdauer bei der Erfassung war Tag 4. Patient*innen unterschieden sich gering zwischen den Regionen mit einem medianen Alter von 64 Jahren und einem Frauenanteil von 40 %. Die Patient*innen waren zur Hälfte beatmet, in 29 % sediert und erhielten in 10 % eine Nierenersatztherapie. Nach 60 Tagen war die Hälfte nach Hause entlassen und ein Viertel der Patient*innen verstorben. Die Ernährungstherapie wird doppelt so häufig in Form enteraler Ernährung (48 %) im Vergleich zur parenteralen Ernährung (24 %) verabreicht. Etwa 39 % der Patient*innen können essen und 10 % erhalten keine Ernährung. Parenterale Ernährung wird in Europa deutlich häufiger als in den anderen Weltregionen angewandt. Die Menge der Ernährung ist in allen Regionen sehr ähnlich mit etwa 1500 kcal und 60 g Protein pro Tag. Eine klare Beziehung mit dem Körpergewicht ist nicht erkennbar. Die Streuung um diese medianen Werte ist sehr groß mit jeweils mehr als der Hälfte der Patient*innen, die um mehr als 25 % nach oben oder unten abweichen. Das nutritionDay-Projekt erlaubt jeder Intensivstation, ihre Praxis numerisch und grafisch mit den durchschnittlichen Werten der weltweiten Daten im Sinne des Benchmarkings jährlich zu vergleichen. Ziel ist es, die Heterogenität der Praxis zu vermindern.

This retrospective study evaluated temporal and regional trends of patient admissions to hospitals, intensive care units (ICU), and intermediate care units (IMCU) as well as outcomes during the COVID-19 pandemic in Austria. We analysed anonymous data from patients admitted to Austrian hospitals with COVID-19 between January 1st, 2020 and December 31st, 2021. We performed descriptive analyses and logistic regression analyses for in-hospital mortality, IMCU or ICU admission, and in-hospital mortality following ICU admission. 68,193 patients were included, 8304 (12.3%) were primarily admitted to ICU, 3592 (5.3%) to IMCU. Hospital mortality was 17.3%; risk factors were male sex (OR 1.67, 95% CI 1.60–1.75, p

Background/Objectives Poor food intake is a major etiological factor of malnutrition. This research aims to describe the prevalence of recent and current low food intake (LIRC) and to identify factors associated with LIRC in adult hospital patients from different medical specialities. Subject/Methods 1865 patients participating in the nutritionDay survey 2016–2020 in Germany were included. LIRC was defined by decreased eating both on nutritionDay and in the week before hospitalisation. Multivariate binary logistic regression was used to identify factors associated with LIRC overall and in different specialities. Results LIRC was observed in 21.1% of all patients, with the highest prevalence in Gastroenterology (26.6%) and the lowest in Neurology (11.2%). Weight loss within three months before nutritionDay (OR 2.62 [95% CI 1.93–3.56]), (very) poor self-rated health (2.17 [1.62–2.91]), female sex (1.98 [1.50–2.61]), uncertain weight loss (1.90 [1.03–3.51]), digestive disease (1.90 [1.40–2.56]), inability to walk without assistance (1.55 [1.14–2.12]) and emergency admission (1.38 [1.02–1.86]) were associated with increased risk, cardiac insufficiency (0.55 [0.37–0.83]) and being in a neurological ward (0.51 [0.28–0.92]) with decreased risk in the total sample. In Gastroenterology and Oncology, estimates were higher than in the entire sample; no significant associations were found in Neurology and Geriatrics, presumably due to the low prevalence of LIRC in Neurology and limited data quality in Geriatrics. Conclusion LIRC is common in German hospital patients and associated with female sex, poor health and decreased functional status. Interdisciplinary differences suggest a discipline-specific approach to dealing with malnutrition.

BACKGROUND & AIMS Across the globe, the prevalence of hospital malnutrition varies greatly depending on the population served and on local socioeconomic conditions. While malnutrition is widely recognized to worsen patient outcomes and add financial burdens to healthcare systems, recent data on hospital malnutrition in Latin America are limited. Our study objectives were: (1) to quantify the prevalence of malnutrition risk in Latin American hospital wards, and (2) to explore associations between nutritional risk status, in-hospital food intake, and health outcomes. METHODS On nutritionDay (nDay), a specific day every year, hospital wards worldwide can participate in a one-day, cross-sectional audit. We analyzed nDay data collected in ten Latin American countries from 2009 to 2015, including demographic and nutrition-related findings for adult patients (≥18 years) from 582 hospital wards/units. Based on patient-reported responses to questions related to the Malnutrition Screening Tool, we determined the prevalence of malnutrition risk (MST score ≥2). We also summarized patient-reported food intake on nDay, and we analyzed staff-collected outcome data at 30 days post-nDay. RESULTS The prevalence of malnutrition risk in the Latin American nDay study population (N = 14,515) was 39.6%. More than 50% of studied patients ate one-half or less of their hospital meal, ate less than normal in the week before nDay, or experienced weight loss in the prior three months. The hospital-mortality hazard ratio was 3.63 (95% CI [2.71, 4.88]; P

The identification of potential hemodynamic indicators to increase the predictive power of stroke-volume variation (SVV) for mean arterial pressure (MAP) and stroke volume (SV) fluid responsiveness.A prospective intervention study.At a single-center university hospital.Nineteen patients during major vascular surgery with 125 fluid interventions.When SVV ≥13% occurred for30 seconds, 250 mL of Ringer's lactate were given within 2 minutes.Hemodynamic variables, such as pulse-pressure variation (PPV) and dynamic arterial elastance (Edyn), were measured by pulse power-wave analysis. The outcomes were MAP and SV responsiveness, defined as an increase of at least 10% of MAP and SV within 5 minutes of the fluid intervention. Of the fluid interventions, 48% were MAP-responsive, and 66% were SV-responsive. The addition of PPV and Edyn cut-off values to the SVV cut-off decreased sensitivity from 1-to-0.66 to-0.82, and concomitantly increased specificity from 0-to- 0.65-to-0.93 for the prediction of MAP and SV responsiveness in the authors' study setting. The areas under the receiver operating characteristic curves of PPV and Edyn for the prediction of MAP responsiveness were 0.79 and 0.75, respectively. The areas under the receiver operating characteristic curves for PPV and Edyn to predict SV responsiveness were 0.85 and 0.77, respectively.The PPV and Edyn showed good accuracy for the prediction of MAP and SV responsiveness in patients with elevated SVV during vascular surgery. Either PPV or Edyn may be used in conjunction with SVV to better predict MAP and SV fluid responsiveness in patients undergoing vascular surgery.

Background Monitoring of adequate food intake is not a priority in hospital patients' care. The present study aimed to examine selective data from the nutritionDay survey to determine the impact of food intake during hospitalization on outcomes according to the nutrition risk status. Methods We conducted a descriptive analysis of selected data from 7 consecutive, annual, and cross-sectional nutritionDay samples from 2009 to 2015. The impact of food intake on outcomes was assessed by univariate and multivariate Cox models controlling for PANDORA scores. Results A total of 7994 adult patients from Colombia, 7243 patients from 9 Latin American countries, and 155,524 patients worldwid were included. Less than half of the patients worldwide consumed their entire meal on nutritionDay (41%). The number of reduced eaters is larger in the "no nutrition risk group" than in the "nutrition risk group" (30% vs 25%). Reduced eating is associated with higher mortality and delayed discharge in patients, regardless of the nutrition risk status. Patients without nutrition risk at the screening who ate "nothing, but were allowed to eat" had 6 times more risk of mortality (hazard ratio, 6.48; 95% CI, 3.5311.87). Conclusions This is the first large-scale study evaluating the relationship of food intake on clinical outcomes showing an increase of in-hospital mortality rates and a reduction in the probability of being discharged home regardless of the nutrition risk status. Traditional screening tools may not identify a group of patients who will become at risk because of reduced intake while in the hospital.

Background & aims: The year 2019 marked the centenary of the publication of the Harris and Benedict equations for estimation of energy expenditure. In October 2019 a Scientific Symposium was organized by the European Society for Clinical Nutrition and Metabolism (ESPEN) in Vienna, Austria, to celebrate this historical landmark, looking at what is currently known about the estimation and measurement of energy expenditure. Methods: Current evidence was discussed during the symposium, including the scientific basis and clinical knowledge, and is summarized here to assist with the estimation and measurement of energy requirements that later translate into energy prescription. Results: In most clinical settings, the majority of predictive equations have low to moderate performance, with the best generally reaching an accuracy of no more than 70%, and often lead to large errors in estimating the true needs of patients. Generally speaking, the addition of body composition measurements did not add to the accuracy of predictive equations. Indirect calorimetry is the most reliable method to measure energy expenditure and guide energy prescription, but carries inherent limitations, greatly restricting its use in real life clinical practice. Conclusions: While the limitations of predictive equations are clear, their use is still the mainstay in clinical practice. It is imperative to recognize specific patient populations for whom a specific equation should be preferred. When available, the use of indirect calorimetry is advised in a variety of clinical settings, aiming to avoid under-as well as overfeeding.

Reduced oxygen consumption (VO2), either due to insufficient oxygen delivery (DO2), microcirculatory hypoperfusion and/or mitochondrial dysfunction, has an impact on the adverse short- and long-term survival of patients after cardiac surgery. However, it is still unclear whether VO2 remains an efficient predictive marker in a population in which cardiac output (CO) and consequently DO2 is determined by a left ventricular assist device (LVAD). We enrolled 93 consecutive patients who received an LVAD with a pulmonary artery catheter in place to monitor CO and venous oxygen saturation. VO2 and DO2 of in-hospital survivors and non-survivors were calculated over the first 4 days. Furthermore, we plotted receiver-operating curves (ROC) and performed a cox-regression analysis. VO2 predicted in-hospital, 1- and 6-year survival with the highest area under the curve of 0.77 (95%CI: 0.6–0.9; p = 0.0004). A cut-off value of 210 mL/min VO2 stratified patients regarding mortality with a sensitivity of 70% and a specificity of 81%. Reduced VO2 was an independent predictor for in-hospital, 1- and 6-year mortality with a hazard ratio of 5.1 (p = 0.006), 3.2 (p = 0.003) and 1.9 (p = 0.0021). In non-survivors, VO2 was significantly lower within the first 3 days (p = 0.010, p < 0.001, p < 0.001 and p = 0.015); DO2 was reduced on days 2 and 3 (p = 0.007 and p = 0.003). In LVAD patients, impaired VO2 impacts short- and long-term outcomes. Perioperative and intensive care medicine must, therefore, shift their focus from solely guaranteeing sufficient oxygen supply to restoring microcirculatory perfusion and mitochondrial functioning.

Background Medical nutrition therapy may be associated with clinical outcomes in critically ill patients with prolonged intensive care unit (ICU) stay. We wanted to assess nutrition practices in European intensive care units (ICU) and their importance for clinical outcomes. Methods Prospective multinational cohort study in patients staying in ICU ≥ 5 days with outcome recorded until day 90. Macronutrient intake from enteral and parenteral nutrition and non-nutritional sources during the first 15 days after ICU admission was compared with targets recommended by ESPEN guidelines. We modeled associations between three categories of daily calorie and protein intake (low: 20 kcal/kg; > 1.2 g/kg) and the time-varying hazard rates of 90-day mortality or successful weaning from invasive mechanical ventilation (IMV). Results A total of 1172 patients with median [Q1;Q3] APACHE II score of 18.5 [13.0;26.0] were included, and 24% died within 90 days. Median length of ICU stay was 10.0 [7.0;16.0] days, and 74% of patients could be weaned from invasive mechanical ventilation. Patients reached on average 83% [59;107] and 65% [41;91] of ESPEN calorie and protein recommended targets, respectively. Whereas specific reasons for ICU admission (especially respiratory diseases requiring IMV) were associated with higher intakes (estimate 2.43 [95% CI: 1.60;3.25] for calorie intake, 0.14 [0.09;0.20] for protein intake), a lack of nutrition on the preceding day was associated with lower calorie and protein intakes (− 2.74 [− 3.28; − 2.21] and − 0.12 [− 0.15; − 0.09], respectively). Compared to a lower intake, a daily moderate intake was associated with higher probability of successful weaning (for calories: maximum HR 4.59 [95% CI: 1.5;14.09] on day 12; for protein: maximum HR 2.60 [1.09;6.23] on day 12), and with a lower hazard of death (for calories only: minimum HR 0.15, [0.05;0.39] on day 19). There was no evidence that a high calorie or protein intake was associated with further outcome improvements. Conclusions Calorie intake was mainly provided according to the targets recommended by the active ESPEN guideline, but protein intake was lower. In patients staying in ICU ≥ 5 days, early moderate daily calorie and protein intakes were associated with improved clinical outcomes. Trial registrationNCT04143503, registered on October 25, 2019.

BACKGROUND: Obesity [Body Mass Index (BMI) > 30 kg/m2] is a risk factor for disease conditions enhancing hospitalization and mortality risks, but higher BMI was paradoxically reported to reduce mortality in several acute and chronic diseases. Unintentional weight loss (WL) is conversely associated with disease development and may worsen patient outcome, but the impact of weight loss and its interaction with obesity in modulating risk of death in hospitalized patients remain undefined. METHODS: We investigated the ESPEN nutritionDay database of non-critically ill hospitalized patients to assess the impact of self-reported 3-month WL (WL1:2.5-6.6%; WL2: 6.6-12.6%, WL3: >12.6%) and its interaction with BMI in modulating 30-day in-hospital mortality. Multivariate Cox regression was used to estimate hazard ratios (HR), with stable weight (WL0) as reference category. RESULTS: In 110835 nDay patients, 30-day mortality increased with increasing WL. Male gender, increasing disease severity index PANDORA score (age, nutrient intake, mobility, fluid status, cancer and main patient group) and not having had surgery also predicted 30-day mortality. HR for 30-day mortality remained significantly higher compared to WL0 for WL2 and WL3 after multiple adjustment. Adjusted HR and its increments through increasing weight loss categories were comparable in lean (BMI30 kg/m2). Impact of gender, PANDORA score and surgery on 30-day mortality were conversely comparable in the three BMI groups. CONCLUSIONS: These results indicate that self-reported WL could represent a relevant prognostic factor in every hospitalized patient. Overweight and obesity per se have no protective impact against WL-associated mortality.

BACKGROUND Acute kidney injury predicts adverse outcomes after cardiac surgery. OBJECTIVES To determine whether ultra-short-term changes (within 120 min) in serum creatinine (SCrea) levels after cardiac surgery predict clinical outcomes (30-day mortality). DESIGN Observational cohort study. SETTING Austrian tertiary referral centre. PATIENTS A total of 7651 patients scheduled to undergo elective cardiac surgery. MAIN OUTCOME MEASURES We analysed SCrea levels measured pre-operatively (baseline) and within 120 min after surgery. We also adjusted the postoperative SCrea levels for fluid balance. Patients were grouped according to the difference between the pre and postoperative SCrea levels (ΔSCreaAdmICU). We performed univariable and multivariable analyses to determine the association between changes in SCrea levels and 30-day mortality. RESULTS After cardiac surgery, the SCrea level decreased in 5923 patients and increased in 1728 patients. Increased SCrea levels were associated with a 21% increase in 30-day mortality. Even minimal increases in SCrea (0 to

Background Patients with severe aortic valve stenosis have a markedly reduced platelet function as measured by a prolonged collagen adenosine diphosphate closure time (CADP-CT) determined by the platelet function analyzer PFA-100. We hypothesized that such patients may benefit from desmopressin when they present with prolonged CADP-CT due to the specific action of desmopressin on von Willebrand factor (VWF) and CADP-CT. Methods In this double-blind, randomized placebo controlled trial, 43 patients undergoing aortic valve replacement (due to severe aortic valve stenosis with CADP-CT > 170 seconds) were given desmopressin 0.3 μg/kg or saline intravenously after induction of anesthesia. Measurement of CADP-CT, factor VIII activity, von Willebrand factor antigen, GpIb binding activity, ristocetin cofactor activity, collagen-binding activity, and multimers were performed after induction of anesthesia, one hour after desmopressin infusion, and 24 hours postoperatively. Results In the majority of patients, baseline values of von Willebrand factor related indices were normal, but increased one hour after infusion of desmopressin by 73% to 90% as compared with placebo. Selective loss of high molecular weight multimers was seen only in a minority of patients. The CADP-CT was greater than 170 seconds in 92% of screened patients, and desmopressin shortened CADP-CT by 48% versus baseline and reduced postoperative blood loss by 42% (p Conclusions Prolonged CADP-CT indicates platelet dysfunction in severe aortic valve stenosis, and can guide the use of desmopressin as an effective prohemostatic agent in patients with severe aortic valve stenosis.

Skeletal muscle area (SMA) in the computed tomography (CT) at the third lumbar vertebra (L3) level is a proxy for whole-body muscle mass but is only performed for clinical reasons. Ultrasound is a promising tool to determine muscle mass at the bedside. It is still unclear how well ultrasound and which ultrasound measuring points can predict CT L3 SMA.This prospective observational trial included 200 non-critically ill patients, who underwent an abdominal CT scan for any clinical reason within 48 h before the ultrasound examination. Ultrasound muscle thickness was evaluated at 3 measuring points on the thigh and 2 measuring points on the upper arm with minimal compression. On the CT scan, the entire L3 SMA was measured based on Hounsfield units. Using a model selection algorithm based on the Bayesian information criterion (BIC) and clinical considerations, a linear prediction model for CT L3 SMA based on the ultrasound muscle thickness and other independent variables was fitted and assessed with cross-validation.67,5% and 32,5% of the patients were from surgical and medical wards, respectively. Mean ultrasound muscle thickness values were between 2,2 and 3,6 cm on the thigh and between 1,4 and 2,8 cm on the upper arm. All ultrasound muscle thickness values were higher in men than in women (P 0,05). CT L3 SMA was 40 cmOne single ultrasound measuring point at the thigh together with sex, height and weight very well predicts CT L3 SMA across different clinical populations. Ultrasound is a safe and bedside method to measure muscle thickness longitudinally to monitor the effects of nutrition and physical therapy.

Summary Background and aims Plasma citrulline and intestinal fatty acid binding protein (I-FABP) are biomarkers reflecting enterocyte function and intestinal mucosal injury. The aim was to describe daily dynamics of citrulline and I-FABP concentrations in association with enteral nutrition (EN) in adult ICU patients. We hypothesized that success or failure of EN is reflected by differences in citrulline and I-FABP levels at admission, as well as in daily dynamics over the first week. Methods The present study was a planned sub-study of the iSOFA study ( ClinicalTrials.gov Identifier: NCT02613000). With delayed informed consent we included adult (18 years or older) patients admitted for unlimited care to 5 ICUs in Europe. Citrulline and I-FABP were assessed and nutritional data recorded daily during the first week of the patients’ ICU stay. Results The study included 224 patients with 693 plasma samples analyzed for citrulline and 695 for I-FABP. The median ICU stay was 2 (IQR 1–4) days and 35 patients (15.6 %) stayed in the ICU for ≥ 7 days. The majority of patients (184/224; 82.1 %) received EN or oral nutrition (ON) during their ICU stay, in 164 patients (73.2 %) nutrition was started within 48 h of admission (early enteral or oral nutrition, EEN/ON). Median biomarker concentrations on admission were: citrulline 24.5 (IQR 18.1–31.7) μmol/L and I-FABP 2763 (1326–4805) pg/mL. Reference range for citrulline was 17–46 μmol/L and for I-FABP 377–2049 pg/mL. Patients with EEN/ON demonstrated an increase in citrulline concentrations over the first week in ICU unlike those not receiving EEN/ON (P = 0.049 for the mean log-citrulline values over time between groups) as well as higher average citrulline concentrations. Success of EEN/ON (80 % of caloric target achieved by day 4) was associated with citrulline values increasing from day 4, whereas a slight decrease was observed with unsuccessful EEN/ON. However, these dynamics over time were not statistically significantly different (P = 0.654). Patients with EEN/ON unexpectedly had I-FABP values higher than those without (average values for all days P = 0.004). Median I-FABP values on day 3 were higher with successful EEN/ON (646 (IQR 313–1116) vs 278 (IQR 190–701) pg/mL, P = 0.022). Conclusions EEN/ON was associated with higher values and different dynamics of citrulline over the first week in ICU. No clear difference of measured biomarkers was seen when patients were compared according to success of EEN/ON. Our study does not allow suggesting certain thresholds of citrulline nor I-FABP that could be used for bedside decision-making with regard to EN. This study was a planned sub-study of the iSOFA study ( ClinicalTrials.gov Identifier: NCT02613000).

Background We previously identified preparation of the internal mammary artery as a risk factor significantly impairing antibiotic tissue penetration into the presternal subcutaneous tissue. We, therefore, adapted our dosing schema regarding preoperative timing to overcome this risk factor. Methods Eight patients who underwent coronary artery bypass grafting with a left internal mammary artery and vein grafts were included in this clinical trial. Cefazolin (4 g) was administered twice (3 hours and 1 hour) prior to skin incision and once during skin closure (2 g). Antibiotic concentrations were measured with subcutaneous microdialysis probes on both sternal sides. Results were directly compared with the previously published patient cohort receiving the standard schema (4 g cefazolin prior to skin incision and 2 g during closure). Results All patients (7 male, 1 female, 69 ± 7 years, 26.3 ± 3.9 kg/m2) survived the perioperative period. Mean area under the curve on the right and left sternal side was 117.0 ± 92.5 μg/mL and 114.5 ± 83.2 μg/mL, respectively (p = 0.95). This was well above the previously measured mean peak tissue concentrations without early preoperative antibiotic administration on the side of mammary artery harvesting (52.4 ± 48.5 μg/mL vs. 13.1 ± 5.8 μg/mL; p = 0.039). The %fT > minimal inhibitory concentration (MIC) for Staphylococcus epidermidis and Staphylococcus aureus during the first 10 hours in presternal tissue was ≥ 70% but did not differ compared with standard schema. Conclusions Early, additional preoperative administration of cefazolin was able to significantly increase peak tissue concentrations during surgery compared with the standard protocol. No difference, however, could be achieved in the percentage of time during which the concentration exceeded the MIC.

Cardiopulmonary bypass (CPB) induces hemolysis, which manifests as plasma free hemoglobin. We investigated in a post hoc analysis of a single-center, blinded, controlled study whether the use of a novel hemoadsorption device (CytoSorb, CytoSorbents Europe GmbH, Berlin, Germany) affects hemolysis during CPB. A total of 35 patients undergoing elective CPB surgery with an expected CPB duration of more than 120 min were included in the analysis. The hemoadsorption device was used in 17 patients (intervention group) and not used in 18 patients (control group). The primary outcome was differences of postoperative free hemoglobin and haptoglobin levels. As secondary outcomes, we investigated differences in postoperative lactate dehydrogenase and bilirubin levels. Postoperative free hemoglobin levels were not significantly different between the groups. However, there were statistically significant differences between the treatment and control groups in the median levels of haptoglobin (58.4 vs. 17.9 mg/dL, respectively; P < 0.01) and lactate dehydrogenase (353.0 vs. 432.0 U/L, respectively; P < 0.05) on postoperative day 1. Thus, in this study, we did not find an effect on hemolysis in patients treated with hemoadsorption, though lower haptoglobin level and higher secondary hemolysis markers on postoperative day 1 in patients not treated with the hemoadsorber may be an indication of some moderate effect of the device. Studies with larger samples are needed to clarify the significance of the small differences detected in this study.

Згідно з новими стандартними операційними процедурами ESPEN були оновлені попередні рекомендації щодо забезпечення найкращого медичного нутритивного забезпечення для критично хворих пацієнтів. Дані рекомендації визначають, хто є пацієнтами в групі ризику, як оцінити нутритивний статус пацієнта ВІТ, як визначити кількість енергії, яку необхідно забезпечити, який обрати шлях для нутритивного забезпечення та як адаптувати пацієнта у відповідності до різних клінічних умов. Також описано, коли слід розпочати і як просуватися в управлінні процесом адекватного забезпечення поживними речовинами. Запропоновано найкраще визначення кількості та походження вуглеводів, жирів і білків. Особлива увага приділяється глутаміну і омега-3 жирним кислотам. Обговорюються конкретні стани, що часто спостерігаються в інтенсивній терапії, такі як пацієнти з дисфагією, виснажені пацієнти, пацієнти з множинними травмами, абдомінальна хірургія, сепсис і ожиріння, з метою ознайомлення практикуючого лікаря з найкращою доказовою терапією. Моніторинг цієї нутритивної терапії обговорюється в окремому документі.

Following the new ESPEN Standard Operating Procedures, the previous guidelines to provide best medical nutritional therapy to critically ill patients have been updated. These guidelines define who are the patients at risk, how to assess nutritional status of an ICU patient, how to define the amount of energy to provide, the route to choose and how to adapt according to various clinical conditions. When to start and how to progress in the administration of adequate provision of nutrients is also described. The best determination of amount and nature of carbohydrates, fat and protein are suggested. Special attention is given to glutamine and omega-3 fatty acids. Particular conditions frequently observed in intensive care such as patients with dysphagia, frail patients, multiple trauma patients, abdominal surgery, sepsis, and obesity are discussed to guide the practitioner toward the best evidence based therapy. Monitoring of this nutritional therapy is discussed in a separate document.

BACKGROUND Malnutrition risk estimates vary greatly, and no robust data on the association between food intake and outcomes exist for hospitals in the United States (U.S.). This study aimed to determine the prevalence of malnutrition risk and to evaluate the impact of food intake on mortality using the nutritionDay in the U.S. dataset. METHODS This study analyzed data from 2009 to 2015 for all adult patients from participating hospitals. Prevalence of malnutrition risk was determined by mapping self-reported nutritionDay survey questions to the Malnutrition Screening Tool (MST). Fine and Gray competing-risk analysis with clustering was used to evaluate the impact of nutrition risk and food intake on patients' 30-day in-hospital mortality, while controlling for age, mobility, and other disease-related factors. RESULTS Analysis included data from 9959 adult patients from 601 wards. The overall prevalence of malnutrition risk (MST score ≥2) was 32.7%. On nutritionDay, 32.1% of patients ate a quarter of their meal or less. Hospital mortality hazard ratio was 3.24 (95% CI: [1.73, 6.07]; P-value < 0.001) for patients eating a quarter compared with those who ate all their meal and increased to 5.99 (95% CI: [3.03, 11.84]; P-value < 0.0001) for patients eating nothing despite being allowed to eat. CONCLUSION This study provides the most robust estimate of malnutrition risk in U.S. hospitalized patients to date, finding that approximately 1 in 3 are at risk. Additionally, patients who have diminished meal intake experience increased mortality risk. These results highlight the ongoing issue of malnutrition in the hospital setting.

Summary Background and aims European and North American guidelines on Parenteral Nutrition (PN) and large Randomized Controlled Trials give divergent advices on nutritional therapeutic strategies for critically ill patients. We therefore investigated differences in therapeutic strategies of clinicians between European and Non-European Intensive Care Units (ICU) regarding start day of PN, preferred route of administration and prescription of total energy targets over the years. Methods In this study 16,032 patients from 1389 different ICUs were included. Data collection was performed in 28 different European and Non-European ICUs from 2007 to 2018 via nutritionDay, a worldwide-standardized one-day multinational cross-sectional audit. Results In this analysis an abrupt delay in PN start days was observed in 2011 (7.64 days (4.31; 19.97); p = 0.001) and 2012 (6.41 days (3.1; 9.72); p = 0.001), which was significantly reversed within the following years until 2018. In European, compared to Non-European countries PN prescription was increased (27% versus 13%). Patients from North-America received significantly less kcal per day compared to Europe (−4.3 kcal kg−1 (−6.9; −1.6); p = 0.001). Conclusions Our study provides further evidence on transatlantic discrepancies in nutritional therapy of ICU patients. Regular audits, such as nutritionDay are substantial for self-reflection of clinical daily practice of intensivists. It is time for worldwide consensus in nutritional therapy by developing worldwide guidelines and supporting standardization in nutrition care of critically ill patients.

Background and aims: Limited data are available on the impact of clinical nutrition over the course of critical illness and post-discharge outcomes. The present study aims to characterize the use of nutrition support in patients admitted to European intensive care units (ICUs), and its impact on clinical outcomes. Here we present the procedures of data collection and evaluation. Methods: Around 100 medical, surgical, or trauma ICUs in 11 countries (Austria, Belgium, Czech Republic, Germany, France, Hungary, Italy, Poland, Spain, Sweden, United Kingdom) participate in the study. In defined months between November 2019 and April 2020, approximately 1250 patients are enrolled if staying in ICU for at least five consecutive days. Data from ICU day 1-4 are collected retrospectively, followed by a prospective observation period from day 5-90 after ICU admission. Data collection includes patient characteristics, nutrition parameters, complications, ICU and hospital length of stay, discharge status, and functional outcomes. For data analysis, the target is 1000 patients with complete data. Statistical analyses will be descriptive, with multivariate analyses adjusted for potential confounders to explore associations between nutritional balance and change in functional status, time-to-weaning from invasive mechanical ventilation, time to first clinical complication, and overall 15, 30 and 90-day survival. Ethics and dissemination: This non-interventional study was reviewed and approved by the ethics committee of the Medical University Vienna, Vienna, Austria (approval number 1678/2019), and the respective ethical committees from participating sites at country and/or local level, as required. Results will be shared with investigators on a country level, and a publication and results presentation at the 2021 ESPEN Congress is planned. (C) 2021 The Authors.

Background/objectives Ultrasound is used to measure muscle and adipose tissue thickness at the bedside. This study was aimed at determining the intra- and inter-examiner reliability for marking points to measure adipose tissue and muscle thickness and assessing it in terms of the performance and evaluation of the corresponding ultrasound scans. Subjects/methods Intra- and inter-examiner reliability was tested in 120 patients. Limb lengths were measured to mark three and two measuring points on both the thighs and upper arms, respectively. Ultrasound scans were performed at each measuring point to evaluate muscle and adipose tissue thickness. Results Regarding the marking of the measuring points, intra- and inter-examiner reliability were high to very high, with correlation coefficients ranging from 0.74 to 0.96. In the performance and evaluation of adipose tissue thickness, all measuring points showed a high to very high reliability, with correlation coefficients ranging from 0.70 to 0.97. In the performance and evaluation of muscle thickness, the ventral measuring point on the thigh and the anterior measuring point on the upper arm showed the best reliability, with high to very high correlation coefficients ranging from 0.77 to 0.93. Conclusions In terms of intra- and inter-examiner reliability, the ventral measuring point on the thigh and the anterior measuring point on the upper arm can be strongly recommended for ultrasound measurements of muscle and adipose tissue thickness.

This prospective cohort study of 16,943 consecutive patients compared phase angle (PhA, foot-to-hand at 50 kHz) and subjective global assessment (SGA) to predict outcomes length of hospital stay (LOS) and in-hospital mortality in patients at risk of malnutrition (NRS-2002 ≥ 3). In 1505 patients, the independent effects on LOS were determined by competing risk analysis and on mortality by logistic regression. In model I, including influence factors age, sex, BMI, and diagnoses, malnourished (SGA B and C) patients had a lower chance for a regular discharge (HR 0.74; 95%CI 0.69–0.79) and an increased risk of mortality (OR 2.87; 95%CI 1.38–5.94). The association of SGA and outcomes regular discharge and mortality was completely abrogated when PhA was added (model II). Low PhA reduced the chance of a regular discharge by 53% in patients with a PhA ≤ 3° (HR 0.47; 95%CI 0.39–0.56) as compared to PhA > 5°. Mortality was reduced by 56% for each 1° of PhA (OR 0.44; 95%CI 0.32–0.61). Even when CRP was added in model III, PhA ≤ 3° was associated with a 41% lower chance for a regular discharge (HR 0.59; 95%CI 0.48–0.72). In patients at risk of malnutrition, the objective measure PhA was a stronger predictor of LOS and mortality than SGA.

Background Acute kidney injury (AKI) predicts adverse outcomes after cardiac surgery. The accuracy of using changes in serum creatinine for diagnosis and grading of AKI is limited in the peri-operative cardiac surgical setting and AKI may be underdiagnosed due to haemodilution from cardiopulmonary bypass priming and the need for intra-operative and postoperative volume resuscitation. Objectives To determine whether the urinary biomarker neprilysin can be used as a marker for the early detection of AKI after cardiac surgery. Design Prospective, observational cohort study. Setting Austrian tertiary referral centre. Patients 96 Patients undergoing elective cardiac surgery with cardiopulmonary bypass. Main outcome measures Differences and discriminatory power of neprilysin levels early after cardiac surgery and on postoperative day 1 between patients with or without AKI, as defined by the Kidney Disease Improving Global Outcomes Group. Results AKI was found in 27% (n=26). The median neprilysin levels on postoperative day 1 were significantly higher in the AKI than in the non-AKI group, 4.0 [interquartile range (IQR): 2 to 6.25] vs. 2.0 ng ml [IQR: 1.0 to 4.5], P = 0.0246, respectively. In addition, the median neprilysin levels at the end of surgery were significantly different between both groups, 5.0 [IQR: 2.0 to 9.0] vs. 2.0 ng ml [IQR: 1.0 to 4.0], P = 0.0055, respectively. The discriminatory power of neprilysin for detecting early AKI corresponded to an area under the curve of 0.77 (95% confidence interval, 0.65 to 0.90). Conclusion Urinary neprilysin has potential as a biomarker for the early detection of AKI after cardiac surgery and has comparable discriminatory power to recently studied AKI biomarkers. Trial registration The trial was registered at ClinicalTrials.gov (NCT03854825, https://clinicaltrials.gov/ct2/show/NCT03854825).

BACKGROUND & AIMS: Phosphate is the main intracellular anion essential for numerous biological processes. Symptoms of hypophosphatemia are non-specific, yet potentially life-threatening. This systematic review process was initiated to gain a global insight into hypophosphatemia, associated morbidity and treatments. METHODS: A systematic review was conducted (PROSPERO CRD42020163191). Nine clinically relevant questions were generated, seven for adult and two for pediatric critically ill patients, and prevalence of hypophosphatemia was assessed in both groups. We identified trials through systematic searches of Medline, EMBASE, Scopus, Cochrane Central Register of Controlled Trials, CINAHL, and Web of Science. Quality assessment was performed using the Cochrane risk of bias tool for randomized controlled trials and the Newcastle-Ottawa Scale for observational studies. RESULTS: For all research questions, we identified 2727 titles in total, assessed 399 full texts, and retained 82 full texts for evidence synthesis, with 20 of them identified for several research questions. Only 3 randomized controlled trials were identified with two of them published only in abstract form, as well as 28 prospective and 31 retrospective studies, and 20 case reports. Relevant risk of bias regarding selection and comparability was identified for most of the studies. No meta-analysis could be performed. The prevalence of hypophosphatemia varied substantially in critically ill adults and children, but no study assessed consecutive admissions to intensive care. In both critically ill adults and children, several studies report that hypophosphatemia is associated with worse outcome (prolonged length of stay and the need for respiratory support, and higher mortality). However, there was insufficient evidence regarding the optimal threshold upon which hypophosphatemia becomes critical and requires treatment. We found no studies regarding the optimal frequency of phosphate measurements, and regarding the time window to correct hypophosphatemia. In adults, nutrient restriction on top of phosphate repletion in patients with refeeding syndrome may improve survival, although evidence is weak. CONCLUSIONS: Evidence on the definition, outcome and treatment of clinically relevant hypophosphatemia in critically ill adults and children is scarce and does not allow answering clinically relevant questions. High quality clinical research is crucial for the development of respective guidelines. ispartof: CLINICAL NUTRITION vol:40 issue:4 pages:1744-1754 ispartof: location:England status: published

Background: Phosphate is the main intracellular anion essential for numerous biological processes. Symptoms of hypophosphataemia are non-specific, yet potentially life-threatening. This systematic review process was initiated to gain a global insight into hypophosphataemia, associated morbidity and treatments. Methods: A systematic review was conducted (PROSPERO CRD42020163191). Nine clinically relevant questions were generated, seven for adult and two for paediatric critically ill patients, and prevalence of hypophosphataemia was assessed in both of these groups.

Background & aims: Despite the presumed importance of preventing and treating micronutrient and mineral deficiencies, it is still not clear how to optimize measurement and administration in critically ill patients. In order to design future comparative trials aimed at optimizing micronutrient and mineral management, an important first step is to gain insight in the current practice of micronutrient, phosphate and magnesium monitoring and administration. Methods: Within the metabolism-endocrinology-nutrition (MEN) section of the European Society of Intensive Care Medicine (ESICM), the micronutrient working group designed a survey addressing current practice in parenteral micronutrient and mineral administration and monitoring. Invitations were sent by the ESICM research department to all ESICM members and past members. Results: Three hundred thirty-four respondents completed the survey, predominantly consisting of physicians (321 [96.1%]) and participants working in Europe (262 [78.4%]). Eighty-one (24.3%) respondents reported to monitor micronutrient deficiencies through clinical signs and/or laboratory abnormalities, and 148 (44.3%) reportedly measure blood micronutrient concentrations on a routine basis. Two hundred ninety-two (87.4%) participants provided specific data on parenteral micronutrient supplementation, of whom 150 (51.4%) reported early administration of combined multivitamin and trace element preparations at least in selected patients. Among specific parenteral micronutrient preparations, thiamine (146 [50.0%]) was reported to be the most frequently administered micronutrient, followed by vitamin B complex (104 [35.6%]) and folic acid (86 [29.5%]). One hundred twenty (35.9%) and 113 (33.8%) participants reported to perform daily measurements of phosphate and magnesium, respectively, whereas 173 (59.2%) and 185 (63.4%) reported to routinely supplement these minerals parenterally. Conclusion: The survey revealed a wide variation in current practices of micronutrient, phosphate and magnesium measurement and parenteral administration, suggesting a risk of insufficient prevention, diagnosis and treatment of deficiencies. These results provide the context for future comparative studies, and identify areas for knowledge translation and recommendations., SCOPUS: ar.j, info:eu-repo/semantics/published

Background: Intraoperative mechanical ventilation may influence postoperative pulmonary complications (PPCs). Current practice during thoracic surgery is not well described. Methods: This is a post-hoc analysis of the prospective multicenter cross-sectional LAS VEGAS study focusing on patients who underwent thoracic surgery. Consecutive adult patients receiving invasive ventilation during general anesthesia were included in a one-week period in 2013. Baseline characteristics, intraoperative and postoperative data were registered. PPCs were collected as composite endpoint until the 5th postoperative day. Patients were stratified into groups based on the use of one lung ventilation (OLV) or two lung ventilation (TLV), endoscopic vs. non-endoscopic approach and ARISCAT score risk for PPCs. Differences between subgroups were compared using χ2 or Fisher exact tests or Student’s t-test. Kaplan–Meier estimates of the cumulative probability of development of PPC and hospital discharge were performed. Cox-proportional hazard models without adjustment for covariates were used to assess the effect of the subgroups on outcome. Results: From 10,520 patients enrolled in the LAS VEGAS study, 302 patients underwent thoracic procedures and were analyzed. There were no differences in patient characteristics between OLV vs. TLV, or endoscopic vs. open surgery. Patients received VT of 7.4 ± 1.6 mL/kg, a PEEP of 3.5 ± 2.4 cmH2O, and driving pressure of 14.4 ± 4.6 cmH2O. Compared with TLV, patients receiving OLV had lower VT and higher peak, plateau and driving pressures, higher PEEP and respiratory rate, and received more recruitment maneuvers. There was no difference in the incidence of PPCs in OLV vs. TLV or in endoscopic vs. open procedures. Patients at high risk had a higher incidence of PPCs compared with patients at low risk (48.1% vs. 28.9%; hazard ratio, 1.95; 95% CI 1.05–3.61; p = 0.033). There was no difference in the incidence of severe PPCs. The in-hospital length of stay (LOS) was longer in patients who developed PPCs. Patients undergoing OLV, endoscopic procedures and at low risk for PPC had shorter LOS. Conclusion: PPCs occurred frequently and prolonged hospital LOS following thoracic surgery. Proportionally large tidal volumes and high driving pressure were commonly used in this sub-population. However, large RCTs are needed to confirm these findings. Trial registration: This trial was prospectively registered at the Clinical Trial Register (www.clinicaltrials.gov; NCT01601223; registered May 17, 2012.)

Summary Background & aims Hospital food consumption can affect patients’ outcome leading to prolonged hospital stay or even increased mortality. In the present study, the nutritionDay database was analyzed (period 2006–2013) to explore the reasons for reduced food intake and associated factors during hospitalization as reported by the patients per se. Methods Data from 113,930 adult patients (male 49.9%; mean age 64.0 ± 18.1 y, mean BMI 25.7 ± 6.0 kg/m2) (from 4519 units, 1358 hospitals, 54 countries) were included. Dietary intake and reasons for reduced food intake were reported and analyzed. Results Only 41.6% of patients reported to have consumed all their served meal, whereas 9.3% ate nothing although allowed to eat. Variables like presence of caner, having nausea/vomiting, feeling tired, not feeling hungry and not liking food's taste increased the likelihood of consuming “¼ of the meal” but not “nothing”. Variables like having gastrointestinal disorder, being bedrest, receiving nutritional support and not liking food's smell increased the likelihood of both decreased (¼ compared to ½) and null (nothing compared to ¼) food consumption (all p Conclusions Food consumption during hospitalization is associated with variables related to both patients’ condition (e.g. clinical, physical) and factors related to the quality of hospital food.

Purpose: Patients with colorectal cancer (CRC) often experience malnutrition and weight loss, largely resulting from reduced dietary intake. The aim of this study was to identify determinants of reduced dietary intake in order to facilitate early recognition of malnutrition and optimise nutritional treatment. Methods: Data from nutritionDay, an international 1-day survey investigating patient, disease and food profiles, were used. To identify determinants of dietary intake, defined as normal vs. reduced in the last week, univariate and multivariate logistic regressions were performed. Results: Of 1131 hospitalised CRC patients, 54% reported reduced dietary intake. Patient- and disease-related characteristics significantly associated with reduced dietary intake were female gender (odds ratio (OR) 1.38), cancer stage III (OR 1.52) or IV (OR 1.70) vs. I, performance status 2 (OR 1.56), 3 (OR 2.37) or 4 (OR 4.15) vs. 0, duration since hospital admission of ≥ 4 days (OR 4–7 days, 1.91; 8–21 days, 1.97; > 21 days, 1.92) vs. < 4 days, and unintentional weight loss (OR 2.56). Additionally, higher symptom scores of pain, weakness, depression, tiredness and lack of appetite were associated with reduced intake. Conclusions: Patient- and disease-related determinants for reduced dietary intake were being female, higher cancer stage, worse performance status, duration since hospital admission ≥ 4 days and unintentional weight loss. Furthermore, multiple symptoms were associated with a reduced dietary intake. Future trials should assess whether early recognition of patients at risk of malnutrition and the combination of treating symptoms and dietary advice result in improved intake and treatment-related outcomes.

Background Respiratory heat exchange is an important physiological process occurring in the upper and lower respiratory tract and is usually completed when inspired gases reach the alveoli. Animal and human studies demonstrated that heat exchange can be modulated by altering pulmonary ventilation and perfusion. The purpose of this study was to examine the effect of acute ventilation-perfusion (V/Q) mismatch on respiratory heat exchange. In clinical practice, monitoring respiratory heat exchange might offer the possibility of real-time tracking of acute V/Q-mismatch. Methods In 11 anesthetized, mechanically ventilated pigs, V/Q-mismatch was established by means of four interventions: single lung ventilation, high cardiac output, occlusion of the left pulmonary artery and repeated whole-lung lavage. V/Q-distributions were determined by the multiple inert gas elimination technique (MIGET). Respiratory heat exchange was measured as respiratory enthalpy using the novel, pre-commercial VQm™ monitor (development stage, Rostrum Medical Innovations, Vancouver, CA). According to MIGET, shunt perfusion of low V/Q compartments increased during single lung ventilation, high cardiac output and whole-lung lavage, whereas dead space and ventilation of high V/Q compartments increased during occlusion of the left pulmonary artery and whole-lung lavage. Results Bohr dead space increased after pulmonary artery occlusion and whole-lung lavage, venous admixture increased during single lung ventilation and whole-lung lavage, PaO2/FiO2 was decreased during all interventions. MIGET confirmed acute V/Q-mismatch. Respiratory enthalpy did not change significantly despite significant acute V/Q-mismatch. Conclusion Clinically relevant V/Q-mismatch does not impair respiratory heat exchange in the absence of additional thermal stressors and may not have clinical utility in the detection of acute changes.

Summary Background & aims Oral nutritional supplements (ONS) can be helpful for nursing home (NH) residents to prevent or treat malnutrition. Presently little is known about the use of ONS in NHs and the factors associated with its use. Thus, the aim of this analysis was to describe the use of ONS in NHs participating in the nutritionDay project and to determine characteristics of NH residents receiving ONS. Methods Data from nutritionDay (nD), a cross-sectional multicenter study with standardized questionnaires on resident and NH level were analyzed. NH residents participating between 2007 and 2014 aged 65 years or older were included. Unit characteristics (2 variables), general residents' characteristics (18), residents' nutritional status (3) and residents' nutrition (4) were of interest as potential predictors of the use of ONS (no vs yes). Univariate binary logistic regression (LR) analyses were performed for all variables, and significant predictors (p Results 13.9% of 23,689 NH residents received ONS. Univariate analysis identified all variables as predictors. After multivariate analysis 19 variables remained in the model (Nagelkerke's R2 = 0.319). Odds ratios (OR [95% Confidence Interval]) of receiving ONS were highest in residents receiving supplementary parenteral nutrition (29.05 [14.85–56.81]; however only 1.1% of all participants) and fortified diet (11.91 [8.52–16.64]; 5.7%). The odds ratio of receiving ONS was 3.26 ([2.86–3.71]; 18.3%) for residents being classified as at risk of malnutrition and 4.56 ([3.86–5.40]; 10.0%) for malnourished residents according to NH staff. Low BMI and weight loss in the last year increased the odds of receiving ONS by 2.34 ([1.93–2.84]; 16.0%) and 1.38 ([1.23–1.54]; 32.8%), respectively. Furthermore, increasing age, cognitive and functional impairment, low food intake on nD, neurological disease and cancer were associated with an increased likelihood of the use of ONS. In NH units with a nutritional expert (67.1%) and units performing a nutritional assessment at least once a month (71.6%), the odds of receiving ONS were also significantly increased (1.89 [1.71–2.10] and 1.17 [1.06–1.29]). Conclusion In NHs who participated in the nutritionDay, ONS are used for residents with poor nutritional and functional status and often in combination with other nutritional interventions. Future studies need to clarify the role of NH staff in the prescription and distribution of ONS and focus on the reasons for and adequacy of the use of ONS in NHs.

Despite high prevalence at hospital admission, disease related malnutrition (DRM) remains under recognized and undertreated. DRM is associated with increased morbidity, hospital readmission rate, and burden for the healthcare system. The compelling need to increase awareness and knowledge through an international survey has triggered the launch of the nutritionDay (ND) concept.ND is a worldwide annual systematic collection and analysis of data in hospital wards, intensive care units and nursing homes. ND is based on questionnaires to systematically collect and analyze the patient's characteristics, food intake and nutrition support, as well as the determinants of their environment (facility, health care personal, etc …). Questionnaires, outcome documentation sheets and step-by-step guidance are available as download in 30 languages.ND has described the nutritional status and behavior of over 150,000 hospitalized patients and nursing home's patients in over 56 participating countries. These data allowed a local, regional, national and international benchmarking at different levels (i.e. type of medical pathologies, care facilities, etc.) and over time. Sixteen peer-reviewed publications have already been released and picture the international scene of DRM.This review presents the 10-year of the ND project development and shows how ND serves all health care professionals to optimize nutrition care and nutrition related structures. ND keeps progressing and is likely to become a standard tool for determining the nutritional status and behavior of hospitalized patients and nursing home's population.
