Background: Enteral nutrition (EN) supply within 48 hours after intensive care unit (ICU) admission improves clinical outcomes. The “new ICU evaluation & development of nutritional support protocol (NICE-NST)” was introduced in an ICU of tertiary academic hospital. This study showed that early EN through protocolized nutritional support would supply more nutrition to improve clinical outcomes.Methods: This study screened 170 patients and 62 patients were finally enrolled; patients who were supplied nutrition without the protocol were classified as the control group (n=40), while those who were supplied according to the protocol were classified as the test group (n=22).Results: In the test group, EN started significantly earlier (3.7±0.4 days vs. 2.4±0.5 days, P=0.010). EN calorie (4.0±1.0 kcal/kg vs. 6.7±0.9 kcal/kg, P=0.006) and protein (0.17±0.04 g/kg vs. 0.32±0.04 g/kg, P=0.002) supplied were significantly higher in the test group. Although EN was supplied through continuous feeding in the test group, there was no difference in complications such as feeding hold due to excessive gastric residual volume or vomit, and hyper- or hypo-glycemia between the two groups. Hospital mortality was significantly lower in the group that started EN within 1.5 days (42.9% vs. 11.8%, P=0.018). The proportion of patients who started EN within 1.5 days was higher in the test group (40.9% vs. 17.5%, P=0.044).Conclusions: The NICE-NST may improve EN supply and mortality of critically ill patients without increasing complications.

Background: Malnutrition in critically ill paitents is closely linked with clinical outcomes. During acute inflammatory states, nutrition cannot reverse the loss of body cell mass completely. Studies on nutritional screening and strategy considering metabolic changes not yet been conducted. We aimed to identify nutrition strategies using the modified Nutrition Risk in the Critically ill (mNUTIRC) score. Methods: Nutrition support data, laboratory nutrition indicators, and prognosis indices were prospectively collected on the 2nd and 7th day after admission. It is to identify the effect of changes on the metabolic status and critical target of nutrition intervention. To discriminate the high-risk group of malnutrition, receiver operating characteristic curves were plotted. Risk factors associated with 28 day-mortality were evaluated using multivariable Cox proportional hazards regression. Results: A total of 490 and 266 patients were analyzed on the 2nd and 7th day, respectively. Only the mNUTRIC score showed significant differences in nutritional risk stratification. The use of vasopressors, hypo-protein supply (< 1.0 g/kg/day), high mNUTRIC score and hypoalbuminemia (

Background Korea has single health insurance system and insurance claim information on almost all medical practices in Korean hospitals is collected and processed by the Health Insurance Review and Assessment Service (HIRA). Since information about prescription of almost all hospitals is available in National Health Insurance (NHI) claim data, recently established the Korea National Antimicrobial Use Analysis System (KONAS) has been using NHI claim data as data source. The purpose of this study is to validate the accuracy of NHI claim data. Methods Data on all antimicrobial agents prescribed in four tertiary-care hospitals in Korea between January 2019 and December 2019 were obtained using NHI claim data extracted by HIRA and data extracted by common data model based on electronic health record (EHR) in each hospital. Antibiotics and antifungal agents according to the Anatomical Therapeutic Chemical class J01 and J02 were included while antiviral, antitubercular, antiparasitic, and topical antimicrobial agents were excluded. Antimicrobial consumption was measured as days of therapy (DOT) and standardized to per 1,000 patient-days. The ratio of monthly antimicrobial consumption calculated using the NHI claim data compared to that calculated using the common data model was demonstrated (HIRA/EHR ratio). Results The monthly HIRA/EHR ratio of broad-spectrum antibiotics predominantly used for hospital-onset infections was 1.08-1.12 and that of broad-spectrum antibiotics predominantly used for community-acquired infections was 1.11-1.21. The monthly HIRA/EHR ratio of other antimicrobial classes are as follows: antibacterial agents predominantly used for resistant gram-positive infections 1.15-1.31, narrow-spectrum beta-lactam agents 1.00-1.05, antifungal agents predominantly used for invasive candidiasis 1.00-1.27, and antibacterial agents predominantly used for extensive antibiotic-resistant gram-negative bacteria 0.70-1.09. Conclusion The monthly antimicrobial consumption calculated using NHI claim data differs from that calculated using EHR data by up to 30%. It would be desirable to establish a system that can analyze and monitor antimicrobial consumption using EHR data in each hospital in Korea in the future.

Data are suggesting that altered antimicrobial concentrations are likely during extracorporeal membrane oxygenation (ECMO).The primary aim of this analysis was to describe the pharmacokinetics of antimicrobials in critically ill adult patients receiving ECMO. Our secondary aim was to determine whether current antimicrobial dosing regimens achieve both effective and safe exposure.This study was a prospective, open-labelled, pharmacokinetic study in six intensive care units from Australia, New Zealand, South Korea and Switzerland. Serial blood samples were collected over a single dosing interval during ECMO for eleven antimicrobials. Pharmacokinetic parameters were estimated using non-compartmental methods. Adequacy of antimicrobial dosing regimens were evaluated using pre-defined concentration exposures associated with maximal clinical outcomes and minimal toxicity risks.We included 993 blood samples from 85 patients. The mean age was 44.7 ± 14.4 years and 61.2% were males. Thirty-eight patients (44.7%) were receiving renal replacement therapy (RRT) during first pharmacokinetic sampling. Large variations (coefficient of variation of ≥30%) in antimicrobial concentrations were seen leading to more than five-fold variations in all PK parameters across all study antimicrobials. Overall, 70 (56.5%) concentration profiles achieved the pre-defined target concentration and exposure range. Target attainment rates were not significantly different between modes of ECMO and RRT. Poor target attainment was observed across the most frequently used antimicrobials for ECMO patients, including for oseltamivir (33.3%), piperacillin (44.4%), and vancomycin (27.3%).Antimicrobial pharmacokinetics were highly-variable in critically ill patients receiving ECMO leading to poor target attainment rates.

Dysbiosis is a microbial imbalance, which often causes diseases and can be triggered by diet. Here, we deter-mined the effect of a nutritionally balanced diet rich in vegetables and whole grains alone and/or in combination with probiotics on the gut microbiota of healthy adults. We conducted a parallel-group randomized trial enrolling 63 healthy participants who were administered either a balanced diet (B-diet group), a probiotic capsule containing Lactobacillus plantarum PMO 08 (probiotics group), or a balanced diet plus probiotic capsule (synbiotics group) once daily for 2 weeks. The gut microbiota of each participant was analyzed via 16S ribosomal RNA MiSeq-based sequencing. Gastrointestinal symptoms and defecation habits were evaluated using questionnaires. The B-diet group showed significantly reduced Firmicutes-to-Bacteroidetes ratio (P

It is necessary to develop a roadmap for antimicrobial usage monitoring in order to perform monitoring of antimicrobial use at the national level properly. Therefore, this study aimed to develop a roadmap for establishing surveillance and monitoring of antimicrobial use in medical institutions at the national level.A modified Delphi study was conducted, including 3 rounds of an online survey and a virtual meeting with 16 expert panels. The survey items were developed based on a literature review of the surveillance systems for antimicrobial use in 12 countries and interviews with experts. The questionnaire was designed to include both the surveillance and benchmarking systems.Regarding the scope of target institutions to be included in the surveillance system, medical institutions for sentinel surveillance had the highest proportion of agreement among the panels (75.0%, 9/12). For the benchmarking system, "tertiary- and secondary-care hospitals" were accepted as the scope of target institutions at the current moment. Furthermore, the National Health Insurance claims and prescription data of individual hospitals were considered appropriate data sources for the surveillance system. As for the measures to promote the participation of hospitals in the benchmarking system, "compensation through the establishment of antimicrobial management fees" and "set the participation in the program as a quality evaluation or accreditation index for hospital evaluation" were accepted.This study provides a roadmap for establishing an antimicrobial use monitoring and benchmarking system for medical institutions at a national level in Korea.

Systemic lupus erythematosus (SLE) is an autoimmune disease, which is characterized by hyperactivation of T and B cells. Human mesenchymal stem cells (hMSCs) ameliorate the progression of SLE in preclinical studies using lupus-prone MRL.Faslpr mice. However, whether hMSCs inhibit the functions of xenogeneic mouse T and B cells is not clear. To address this issue, we examined the in vitro effects of hMSCs on T and B cells isolated from MRL.Faslpr mice. Naïve hMSCs inhibited the functions of T cells but not B cells. hMSCs preconditioned with IFN-γ (i) inhibited the proliferation of and IgM production by B cells, (ii) attracted B cells for cell–cell interactions in a CXCL10-dependent manner, and (iii) inhibited B cells by producing indoleamine 2,3-dioxygenase. In summary, our data demonstrate that hMSCs exert therapeutic activity in mice in three steps: first, naïve hMSCs inhibit the functions of T cells, hMSCs are then activated by IFN-γ, and finally, they inhibit B cells.

Rationale: Systemic lupus erythematosus (SLE) is a multi-organ autoimmune disease characterized by autoantibody production by hyper-activated B cells. Although mesenchymal stem cells (MSCs) ameliorate lupus symptoms by inhibiting T cells, whether they inhibit B cells has been controversial. Here we address this issue and reveal how to prime MSCs to inhibit B cells and improve the efficacy of MSCs in SLE. Methods: We examined the effect of MSCs on purified B cells in vitro and the therapeutic efficacy of MSCs in lupus-prone MRL.Faslpr mice. We screened chemicals for their ability to activate MSCs to inhibit B cells. Results: Mouse bone marrow-derived MSCs inhibited mouse B cells in a CXCL12-dependent manner, whereas human bone marrow-derived MSCs (hMSCs) did not inhibit human B (hB) cells. We used a chemical approach to overcome this hurdle and found that phorbol myristate acetate (PMA), phorbol 12,13-dibutyrate, and ingenol-3-angelate rendered hMSCs capable of inhibiting IgM production by hB cells. As to the mechanism, PMA-primed hMSCs attracted hB cells in a CXCL10-dependent manner and induced hB cell apoptosis in a PD-L1-dependent manner. Finally, we showed that PMA-primed hMSCs were better than naive hMSCs at ameliorating SLE progression in MRL.Faslpr mice. Conclusion: Taken together, our data demonstrate that phorbol esters might be good tool compounds to activate MSCs to inhibit B cells and suggest that our chemical approach might allow for improvements in the therapeutic efficacy of hMSCs in SLE.

Our study aimed to describe the population pharmacokinetics (PK) of vancomycin in critically ill patients receiving extracorporeal membrane oxygenation (ECMO), including those receiving concomitant renal replacement therapy (RRT). Dosing simulations were used to recommend maximally effective and safe dosing regimens. Serial vancomycin plasma concentrations were measured and analyzed using a population PK approach on Pmetrics. The final model was used to identify dosing regimens that achieved target exposures of area under the curve (AUC(0-24)) of 400–700 mg · h/liter at steady state. Twenty-two patients were enrolled, of which 11 patients received concomitant RRT. In the non-RRT patients, the median creatinine clearance (CrCL) was 75 ml/min and the mean daily dose of vancomycin was 25.5 mg/kg. Vancomycin was well described in a two-compartment model with CrCL, the presence of RRT, and total body weight found as significant predictors of clearance and central volume of distribution (V(c)). The mean vancomycin renal clearance and V(c) were 3.20 liters/h and 29.7 liters respectively, while the clearance for patients on RRT was 0.15 liters/h. ECMO variables did not improve the final covariate model. We found that recommended dosing regimens for critically ill adult patients not on ECMO can be safely and effectively used in those on ECMO. Loading doses of at least 25 mg/kg followed by maintenance doses of 12.5–20 mg/kg every 12 h are associated with a 97–98% probability of efficacy and 11–12% probability of toxicity, in patients with normal renal function. Therapeutic drug monitoring along with reductions in dosing are warranted for patients with renal impairment and those with concomitant RRT.

Systematic protocols for the management of outpatient parenteral antimicrobial therapy (OPAT) and information on the current status of a prescription of parenteral antibiotics for outpatients and referred patients are lacking in the Republic of Korea. This study aimed to describe the current status of OPAT at a tertiary care hospital in Korea.This was a retrospective study of outpatients and referral patients who were prescribed parenteral antibiotics from July to December 2019. We reviewed the prescribed antimicrobials, indications for antimicrobial therapy, institution administering the antimicrobial injections, and pre- and post-prescription management.Of the 577 prescriptions assessed in this study, 399 (69.2%) and 178 (30.8%) were delivered using the referral and outpatient models, respectively. About 70% of OPATs were prescribed in the pulmonology, infectious diseases, orthopedics, gastroenterology, and hematology departments. Five antibiotics (ertapenem [26.0%], ceftriaxone [12.8%], kanamycin [11.8%], amikacin [10.1%], and cefazolin [8.5%]) accounted for 69.2% of the total OPATs. Urinary tract (27.3%), respiratory (20.8%), and intra-abdominal (15.9%) infections were the most frequent indications for OPAT. After prescription, there were 295 (73.9%) and 150 (84.3%) follow-up visits in the referral and outpatient models, respectively (We found that a significant number of OPATs were prescribed, follow-up visits were not performed in the case of about a quarter of prescriptions, and laboratory monitoring was not fully conducted in more than half of the cases. Therefore, it is necessary to establish an appropriate management program for OPAT. Considering the limited resources and the distribution of OPAT prescriptions, an effective strategy may be to select the frequently-used antibiotics or frequently-prescribing departments and start the program with them.

The Korea National Antimicrobial Use Analysis System (KONAS), a benchmarking system for antimicrobial use in hospitals, provides Korean Standardized Antimicrobial Administration Ratio (K-SAAR) for benchmarking. This article describes K-SAAR predictive models to enhance the understanding of K-SAAR, an important benchmarking strategy for antimicrobial usage in KONAS.We obtained medical insurance claims data for all hospitalized patients aged ≥ 28 days in all secondary and tertiary care hospitals in South Korea (n = 347) from January 2019 to December 2019 from the Health Insurance Reviewamp; Assessment Service. Modeling was performed to derive a prediction value for antimicrobial use in each institution, which corresponded to the denominator value for calculating K-SAAR. The prediction values of antimicrobial use were modeled separately for each category, for all inpatients and adult patients (aged ≥ 15 years), using stepwise negative binomial regression.The final models for each antimicrobial category were adjusted for different significant risk factors. In the K-SAAR models of all aged patients as well as adult patients, most antimicrobial categories included the number of hospital beds and the number of operations as significant factors, while some antimicrobial categories included mean age for inpatients, hospital type, and the number of patients transferred from other hospitals as significant factors.We developed a model to predict antimicrobial use rates in Korean hospitals, and the model was used as the denominator of the K-SAAR.

Despite the surge in use of extracorporeal membrane oxygenation (ECMO) in the adult intensive care unit, little guidance is available on the appropriate dosing of antimicrobials in this setting. Ceftriaxone is an antimicrobial with a high affinity to plasma protein, a property identified in the literature as susceptible to sequestration into extracorporeal circuits and hypothesised to require dosage adjustments in this setting.The aim of this study was to describe the pharmacokinetics of ceftriaxone and identify the best dosing regimen for critically ill adult patients receiving ECMO.Serial blood samples were taken from patients receiving both ECMO and ceftriaxone. Total and unbound drug concentrations were measured in plasma by chromatographic assay and analysed using a population pharmacokinetic approach with PmetricsIn total, 14 patients were enrolled, of which three were receiving renal replacement therapy (RRT). Total and unbound ceftriaxone was best described in a two-compartment model with total body weight, serum albumin concentrations, creatinine clearance (CrCL), and the presence of RRT included as significant predictors of pharmacokinetics. Patients not on RRT generated a mean renal clearance of 0.90 L/h, non-renal clearance of 0.33 L/h, and central volume of distribution of 7.94 L. Patients on RRT exhibited a mean total clearance of 1.18 L/h. ECMO variables were not significant predictors of ceftriaxone pharmacokinetics. Steady-state dosing simulations found that dosages of 1 g every 12 h and 2 g every 24 h achieved90% probabilities of target attainment in patients with CrCL of 0 mL/min with RRT and 30 and 100 mL/min and various serum albumin concentrations (17 and 26 g/L).Dosing recommendations for critically ill adult patients not on ECMO appear to be sufficient for patients on ECMO. Patients exhibiting augmented renal clearance ( 130 mL/min) or treatment of less susceptible pathogens may require higher doses, which requires further investigation.

Natural killer (NK) cell-based therapy has been studied for the treatment of patients with cancers, but the inadequate infiltration of NK cells into solid tumors remains a big challenge to its clinical application. In this study, we examined the interaction between NK cells and endothelial cells, which might play a major role in NK cell homing to solid tumors. We found that endothelial cells were activated by TNF-α and IL-1β, which were produced by tumor-associated CD11b

Objectives The aim of this study was to describe current status of outpatient parenteral antimicrobial therapy (OPAT) at a tertiary care hospital in the Republic of Korea. Methods This retrospective study was conducted on outpatients and referral patients who had a prescription of parenteral antibiotics from July to December 2019. We reviewed the prescribed antimicrobials, the indication of antimicrobial therapy, where patients administered antimicrobial injection and management of pre- and post- prescriptions. Results Of the 577 episodes included in this study, 399 (69.2%) were delivered by referral model, 178 (30.8%) by outpatient model. About 70% of OPATs were prescribed in the pulmonology, infectious diseases, orthopedics, gastroenterology, and hematology departments. Five antibiotics (ertapenem (26.0%), ceftriaxone (12.8%), kanamycin (11.8%), amikacin (10.1%), and cefazolin (8.5%)) accounted for 69.2% of the total OPATs. Urinary tract infections (27.3%), respiratory infections (20.8%), and intra-abdominal infections (15.9%) are the most frequent indications of OPAT. After prescription, there were 295 (73.9%) follow-up visits in referral model and 150 (84.3%) in outpatient model (p

Our study aimed to describe the population pharmacokinetics (PK) of piperacillin and tazobactam in patients on extracorporeal membrane oxygenation (ECMO), with and without renal replacement therapy (RRT). We also aimed to use dosing simulations to identify the optimal dosing strategy for these patient groups. Serial piperacillin and tazobactam plasma concentrations were measured with data analyzed using a population PK approach that included staged testing of patient and treatment covariates. Dosing simulations were conducted to identify the optimal dosing strategy that achieved piperacillin target exposures of 50% and 100% fraction of time free drug concentration is above MIC (%fT(>MIC)) and toxic exposures of greater than 360 mg/liter. The tazobactam target of percentage of time free concentrations of >2 mg/liter was also assessed. Twenty-seven patients were enrolled, of which 14 patients were receiving concurrent RRT. Piperacillin and tazobactam were both adequately described by two-compartment models, with body mass index, creatinine clearance, and RRT as significant predictors of PK. There were no substantial differences between observed PK parameters and published parameters from non-ECMO patients. Based on dosing simulations, a 4.5-g every 6 hours regimen administered over 4 hours achieves high probabilities of efficacy at a piperacillin MIC of 16 mg/liter while exposing patients to a

The susceptibility of cancer cells to natural killer (NK) cell-mediated cytotoxicity depends on the balance of activating and inhibitory ligands expressed on their surface. Although many types of cancer cells are killed by NK cells, non-small-cell lung cancer (NSCLC) cells are relatively resistant to NK cell-mediated cytotoxicity. In this study, we showed that several NSCLC cell lines have differential sensitivity to NK cell-mediated cytotoxicity: NCI-H522 cells were highly sensitive, but A549, NCI-H23, NCI-H1915, and NCI-H1299 were resistant. Among activating ligands such as CD48, HLA-A/B/G, ICAM-1, MICA/B, and ULBPs, only CD48 rendered NCI-H522 cells susceptible to NK cell-mediated cytotoxicity, which was proved by using CD48 siRNA and neutralizing antibody. CD48-positive NCI-H522 cells established a more stable contact with NK cells than did CD48-negative A549 and CD48 siRNA cell-transfected NCI-H522 cells. Taken together, these data demonstrate that CD48-positive NSCLC cells might be susceptible to NK cell-mediated cytotoxicity, which provide information on how to stratify NSCLC patients potentially responsive to NK-cell therapy.

PurposeThe initial nutritional delivery policy for patients with sepsis admitted to the intensive care unit (ICU) is not fully elucidated. This study aimed to determine whether initial adequate nutrition supply and route of nutrition delivery during the first week of sepsis onset may improve the clinical outcomes of critically ill septic patients. MethodsWe examined 834 adult patients with sepsis and septic shock in the ICU between November 2013 and May 2017 retrospectively. Poisson log-linear and Cox regressions were performed to assess the relationship between clinical outcomes, sex, modified nutrition risk in the critically ill (mNUTRIC) scores, sequential organ failure assessment and acute physiology and chronic health evaluation scores, route of nutrition delivery, and daily energy and protein delivery during the first week since sepsis onset. ResultsPatients who had higher protein intakes during the first week since sepsis onset had lower in-hospital mortality, while higher energy intakes were associated with lower the 30-day mortality. Route of nutrition delivery was not associated with 1-year mortality in the group with > 70% of the nutritional requirement; however, enteral feeding (EN) with supplemental parenteral nutrition (PN) was superior to only EN or only PN in patients who were underfed. ConclusionFor patients with sepsis and septic shock, a high daily average protein intake may lower in-hospital mortality and a high energy intake may lower the 30-day mortality, especially for patients with high mNUTRIC scores. For underfed patients, EN with supplemental PN may be better than EN or PN alone.

These guidelines were developed as a part of the 2021 Academic R&D Service Project of the Korea Disease Control and Prevention Agency in response to requests from healthcare professionals in clinical practice for guidance on developing antimicrobial stewardship programs (ASPs). These guidelines were developed by means of a systematic literature review and a summary of recent literature, in which evidence-based intervention methods were used to address key questions about the appropriate use of antimicrobial agents and ASP expansion. These guidelines also provide evidence of the effectiveness of ASPs and describe intervention methods applicable in Korea.

Natural killer (NK) cell killing of melanoma cells involves perforin-mediated delivery of granzymes from NK cells to cancer cells; however, how melanoma cells die remains poorly characterized. Here, we examined the dying process of melanoma cells by using time-lapse imaging. Upon contact with NK cells, B16-F10 cells rounded and most of them showed membrane rupture (98 min); however, B16 parent cells showed writhing and delayed membrane rupture (235 min). This morphological difference depended on the expression levels of myosin regulatory light chain 9 (MYL9) but not activating ligands (CD112, CD155, Rae-1, and MULT-1), SPI, FasL, or PD-L1. Taken together, our data show that melanoma cells show two distinct types of morphological changes upon contact with NK cells and suggest that a strategy to decrease MYL9 expression by melanoma cells may improve the efficacy of NK cell–based immunotherapy.

Although specialized pharmacists have been suggested to be essential members of antimicrobial stewardship programs (ASPs), not all hospitals in Korea operate ASPs with pharmacists involved. We aimed to evaluate the association of involvement of clinical pharmacists as team members of multidisciplinary ASPs with the incidence of antimicrobial-related adverse drug events (ADEs). Five tertiary teaching hospitals participated in this retrospective cohort study. At each participating hospital, we randomly selected 1000 participants among patients who had received systemic antimicrobial agents for more than one day during the first quarter of 2017. We investigated five categories of antimicrobial-related ADEs: allergic reactions, hematologic toxicity, nephrotoxicity, hepatotoxicity, and antimicrobial-related diarrhea. Multivariate logistic regression analysis was used to evaluate the potential impact of pharmacist involvement in ASPs on the incidence of ADEs. A total of 1195 antimicrobial-related ADEs occurred in 618 (12.4%) of the 4995 patients included in the analysis. The overall rate of ADE occurrence was 17.4 per 1000 patient days. Hospitals operating ASPs with pharmacists showed significantly lower AE incidence proportions than other hospitals (8.9% vs. 14.7%, p &lt, 0.001). Multidisciplinary ASPs that included clinical pharmacists reduced the risk of antimicrobial-related ADEs by 38% (adjusted odds ratio 0.62, 95% confidence interval 0.50–0.77). Our results suggest that the active involvement of clinical pharmacists in multidisciplinary ASPs may contribute to reduce the incidence of antimicrobial-related ADEs in hospitalized patients.

The initial nutritional delivery policy for patients with sepsis admitted to the intensive care unit (ICU) has not been fully elucidated. We aimed to determine whether an initial adequate nutrition supply and route of nutrition delivery during the first week of sepsis onset improve clinical outcomes of critically ill patients with sepsis. We reviewed adult patients with sepsis and septic shock in the ICU in a single tertiary teaching hospital between 31 November 2013 and 20 May 2017. Poisson log-linear and Cox regressions were performed to assess the relationships between clinical outcomes and sex, modified nutrition risk in the critically ill score, sequential organ failure assessment score, route of nutrition delivery, acute physiology and chronic health evaluation score, and daily energy and protein delivery during the first week of sepsis onset. In total, 834 patients were included. Patients who had a higher protein intake during the first week of sepsis onset had a lower in-hospital mortality (adjusted hazard ratio (HR), 0.55; 95% confidence interval (CI), 0.39–0.78; p = 0.001). A higher energy intake was associated with a lower 30-day mortality (adjusted HR, 0.94; 95% CI, 0.90–0.98; p = 0.003). The route of nutrition delivery was not associated with 1-year mortality in the group which was underfed; however, in patients who met > 70% of their nutritional requirement, enteral feeding (EN) with supplemental parenteral nutrition (PN) was superior to only EN (p = 0.016) or PN (p = 0.042). In patients with sepsis and septic shock, a high daily average protein intake may lower in-hospital mortality, and a high energy intake may lower the 30-day mortality, especially in those with a high modified nutrition risk in the critically ill scores. In patients who receive adequate energy, EN with supplemental PN may be better than only EN or PN, but not in underfed patients.
