OBJECTIVE:
To investigate whether dynamic monitoring of citrulline (Cit) has guiding value for early enteral nutrition (EN) in patients with severe gastrointestinal injury.
METHODS:
A observational study was conducted. A total of 76 patients with severe gastrointestinal injury admitted to different intensive care units of Suzhou Hospital Affiliated to Nanjing Medical University from February 2021 to June 2022 were enrolled. Early EN was performed in 24-48 hours after admission as recommended by the guidelines. Those who did not terminate EN after 7 days were enrolled in the early EN success group, and those who terminated EN within 7 days due to persistent feeding intolerance or deterioration of general condition were enrolled in the early EN failure group. There was no intervention during the treatment. Serum Cit levels were measured by mass spectrometry at admission, before EN starting and EN 24 hours, respectively, and the changes in Cit within EN 24 hours (ΔCit) were calculated (ΔCit = EN 24-hour Cit-Cit before EN starting). Receiver operator characteristic curve (ROC curve) was plotted to investigate the predictive value of ΔCit for early EN failure, and the optimal predictive value was calculated. Multivariate unconditional Logistic regression was used to analyze the independent risk factors for early EN failure and death at 28 days.
RESULTS:
Seventy-six patients were enrolled in the final analysis, of which 40 succeeded in early EN and 36 failed. There were significant differences in age, main diagnosis, acute physiology and chronic health evaluation II (APACHE II) score at admission, blood lactic acid (Lac) before EN initiation and ΔCit between the two groups. Multivariate Logistic regression analysis showed that age [odds ratio (OR) = 0.929, 95% confidence interval (95%CI) was 0.874-0.988, P = 0.018], ΔCit (OR = 2.026, 95%CI was 1.322-3.114, P = 0.001) and increased feeding rate within 48 hours (OR = 13.719, 95%CI was 1.795-104.851, P = 0.012) were independent risk factors for early EN failure in patients with severe gastrointestinal injury. ROC curve analysis showed that ΔCit had a good predictive value for early EN failure in patients with severe gastrointestinal injury [area under the ROC curve (AUC) = 0.787, 95%CI was 0.686-0.887, P < 0.001], and the optimal predictive value of ΔCit was 0.74 μmol/L (sensitivity was 65.0%, specificity was 75.0%). Combined with the optimal predictive value of ΔCit, "overfeeding" was defined as ΔCit < 0.74 μmol/L and increased feeding within 48 hours. Multivariate Logistic regression analysis showed that age (OR = 0.825, 95%CI was 0.732-0.930, P = 0.002), APACHE II score (OR = 0.696, 95%CI was 0.518-0.936, P = 0.017) and early EN failure (OR = 181.803, 95%CI was 3.916-8 439.606, P = 0.008) were independent risk factors for 28-day death in patients with severe gastrointestinal injury. The new variable "overfeeding" was also associated with an increased risk of death at 28 days (OR = 27.816, 95%CI was 1.023-755.996, P = 0.048).
CONCLUSIONS
Dynamic monitoring of Cit has guiding value for early EN in patients with severe gastrointestinal injury.

OBJECTIVE:
To develop a mortality prediction model for critically ill patients based on multidimensional and dynamic clinical data collected by the hospital information system (HIS) using random forest algorithm, and to compare the prediction efficiency of the model with acute physiology and chronic health evaluation II (APACHE II) model.
METHODS:
The clinical data of 10 925 critically ill patients aged over 14 years old admitted to the Third Xiangya Hospital of Central South University from January 2014 to June 2020 were extracted from the HIS system, and APACHE II scores of the critically ill patients were extracted. Expected mortality of patients was calculated according to the death risk calculation formula of APACHE II scoring system. A total of 689 samples with APACHE II score records were used as the test set, and the other 10 236 samples were used to establish the random forest model, of which 10% (n = 1 024) were randomly selected as the validation set and 90% (n = 9 212) were selected as the training set. According to the time series of 3 days before the end of critical illness, the clinical characteristics of patients such as general information, vital signs data, biochemical test results and intravenous drug doses were selected to develope a random forest model for predicting the mortality of critically ill patients. Using the APACHE II model as a reference, receiver operator characteristic curve (ROC curve) was drawn, and the discrimination performance of the model was evaluated through the area under the ROC curve (AUROC). According to the precision and recall, Precision-Recall curve (PR curve) was drawn, and the calibration performance of the model was evaluated through the area under the PR curve (AUPRC). Calibration curve was drawn, and the consistency between the predicted event occurrence probability of the model and the actual occurrence probability was evaluated through the calibration index Brier score.
RESULTS:
Among the 10 925 patients, there were 7 797 males (71.4%) and 3 128 females (28.6%). The average age was (58.9±16.3) years old. The median length of hospital stay was 12 (7, 20) days. Most patients (n = 8 538, 78.2%) were admitted to intensive care unit (ICU), and the median length of ICU stay was 66 (13, 151) hours. The hospitalized mortality was 19.0% (2 077/10 925). Compared with the survival group (n = 8 848), the patients in the death group (n = 2 077) were older (years old: 60.1±16.5 vs. 58.5±16.4, P < 0.01), the ratio of ICU admission was higher [82.8% (1 719/2 077) vs. 77.1% (6 819/8 848), P < 0.01], and the proportion of patients with hypertension, diabetes and stroke history was also higher [44.7% (928/2 077) vs. 36.3% (3 212/8 848), 20.0% (415/2 077) vs. 16.9% (1 495/8 848), 15.5% (322/2 077) vs. 10.0% (885/8 848), all P < 0.01]. In the test set data, the prediction value of random forest model for the risk of death during hospitalization of critically ill patients was greater than that of APACHE II model, which showed by that the AUROC and AUPRC of random forest model were higher than those of APACHE II model [AUROC: 0.856 (95% confidence interval was 0.812-0.896) vs. 0.783 (95% confidence interval was 0.737-0.826), AUPRC: 0.650 (95% confidence interval was 0.604-0.762) vs. 0.524 (95% confidence interval was 0.439-0.609)], and Brier score was lower than that of APACHE II model [0.104 (95% confidence interval was 0.085-0.113) vs. 0.124 (95% confidence interval was 0.107-0.141)].
CONCLUSIONS
The random forest model based on multidimensional dynamic characteristics has great application value in predicting hospital mortality risk for critically ill patients, and it is superior to the traditional APACHE II scoring system.

Chinese Critical Care Medicine 2023;35(5):538-544
OBJECTIVE:
To systematically assess the efficacy of traditional Chinese therapy in the treatment of ICU-acquired weakness (ICU-AW).
METHODS:
PubMed, Cochrane Library, Embase, Web of Science, CNKI, Wanfang, VIP were retrieved by computer and were used to collect a randomized controlled trials (RCT) of traditional Chinese therapy for ICU-AW. The retrieval time was from databases establishment to December 2021. After 2 researchers independently screened the literature, extracted data and evaluated the risk of bias included in the study, and RevMan 5.4 software was used for Meta-analysis.
RESULTS:
334 articles were selected, totally 13 clinical studies and 982 patients were included, including 562 in the trial group and 420 in the control group. Meta-analysis results showed that traditional Chinese therapy could improve clinical efficacy of ICU-AW patients [relative risk (RR) = 1.35, 95% confidence interval (95%CI) was 1.20 to 1.52, P < 0.000 01], improve the muscle strength [Medical Research Council score (MRC score); standardized mean difference (SMD) = 1.00, 95%CI was 0.67 to 1.33, P < 0.000 01], improve daily life ability [modified Barthel index score (MBI score); SMD = 1.67, 95%CI was 1.20 to 2.14, P < 0.000 01], shorten mechanical ventilation time (SMD = -1.47, 95%CI was -1.84 to -1.09, P < 0.000 01), reduce the length of intensive care unit (ICU) stay [mean difference (MD) = -3.28, 95%CI was -3.89 to -2.68, P < 0.000 01], reduce the total hospitalization time (MD = -4.71, 95%CI was -5.90 to -3.53, P < 0.000 01), reduce tumor necrosis factor-α (TNF-α; MD = -4.55, 95%CI was -6.39 to -2.70, P < 0.000 01) and interleukin-6 (IL-6; MD = -5.07, 95%CI was -6.36 to -3.77, P < 0.000 01). There was no obvious advantage in reducing the severity of the disease [acute physiology and chronic health evaluation II (APACHE II; SMD = -0.45, 95%CI was -0.92 to 0.03, P = 0.07).
CONCLUSIONS
Based on the current research, traditional Chinese therapy can improve the clinical efficacy of ICU-AW, improve muscle strength and daily life ability, shorten mechanical ventilation, the length of ICU stay and total hospitalization time, reduce TNF-α and IL-6. But traditional Chinese therapy can not reduce the overall disease severity.

Objective: To analyze the correlation of bispectral index (BIS) with the prognosis of patients with acute severe carbon monoxide poisoning (ASCMP) and its predictive value of adverse outcomes. Methods: In March 2021, 106 ASCMP patients who were treated in Harrison International Peace Hospital Affiliated to Hebei Medical University from January 2019 to December 2020 were taken as research objects. All patients underwent 24-hour BIS monitoring after admission, and were divided into good prognosis group (n=75) and poor prognosis group (n=31) according to the prognosis of the patients' cranial nerve function after 60 d. The general conditions, Acute Physiology and Chronic Health Evaluation Ⅱ (APACHEⅡ) score, Glasgow Coma Scale (GCS) score at admission and 24-hour BIS mean were compared between the two groups. Pearson correlation analysis was used to analyze the correlations between the 24-hour BIS mean and GCS score at admission, APACHEⅡ score and coma time. The receiver operating characteristic (ROC) curve was drawn to analyze the predictive value of 24-hour BIS mean, GCS score at admission, APACHEⅡ score and coma time on adverse outcome of ASCMP patients. Results: The coma time and APACHEⅡ score of the patients in the poor prognosis group were significantly higher than those in the good prognosis group, the GCS score at admission and 24-hour BIS mean were significantly lower than those in the good prognosis group (P<0.05) . Pearson correlation analysis showed that the 24-hour BIS mean was positively correlated with the GCS score at admission, and negatively correlated with the APACHEⅡ score, coma time (r=0.675, -0.700, -0.565, P<0.001) . The 24-hour BIS mean had the highest predictive value for adverse outcome of ASCMP patients, with a cut-off value of 74, the area under the curve was 0.883 (95%CI: 0.814-0.951, P<0.001) , and the sensitivity and specificity were 73.3% and 87.1%, respectively. Conclusion: The 24-hour BIS mean has a good correlation with the acute brain nerve injury, the severity of the disease and coma time of patients with ASCMP. And it has a high predictive value for the adverse outcome in patients with ASCMP.

Journal of Central South University(Medical Sciences) 2021;46(11):1212-1219
OBJECTIVES:
Sepsis associated encephalopathy (SAE) is a common neurological complication of sepsis. Delirium is a common symtom of SAE. The pathophysiology of SAE is still unclear, but several likely mechanisms have been proposed, such as mitochondrial and endothelial dysfunction, neurotransmission disturbances, derangements of calcium homeostasis, cerebral microcirculation dysfunction, and brain hypoperfusion. Near-infrared spectroscopy (NIRS) is a non-invasive measure for regional cerebral oxygen saturation (rSO
METHODS:
A total of 48 septic patients who admitted to the intensive care unit (ICU) of Xiangya Hospital, Central South University from August 2017 to May 2018, were retrospectively study. Septic shock was diagnosed according to the criteria of sepsis 3.0 defined by the American Association of Critical Care Medicine and the European Society of Critical Care Medicine. NIRS monitoring was performed during the first 6 hours admitted to ICU with sensors placed on the bilateral forehead of patients. The maximum (rSO
RESULTS:
The overall 28-day mortality of septic shock patients was 47.92% (23/48), and the incidence of delirium was 18.75% (9/48). The rSO
CONCLUSIONS
Cerebral anoxia and hyperoxia, as well as the large fluctuation of cerebral oxygen saturation are important factors that affect the outcomes and the incidence of delirium in septic shock patients, which should be paid attention to in clinical practice. Dynamic monitoring of cerebral oxygen saturation and maintain its stability may be of great significance in patients with septic shock.

INTRODUCTION:
Singapore was one of the first countries affected by the coronavirus disease 2019 (COVID-19) pandemic but has been able to prevent its healthcare system and intensive care units (ICU) from being overwhelmed. We describe the clinical features, management and outcomes of COVID-19 patients with respiratory failure admitted to our ICU.
MATERIALS AND METHODS:
A case series of COVID-19 patients admitted to our ICU for respiratory failure from 7 February, with data censoring at 30 June 2020, was performed from a review of medical records.
RESULTS:
Twenty-two COVID-19 patients were admitted to our ICU for respiratory failure. The median age was 54.5 years (IQR 30-45.5), 72.7% were male and had at least one comorbidity. The Sequential Organ Failure Assessment (SOFA) and Acute Physiology and Chronic Health Evaluation (APACHE) II scores were 2.5 (IQR 1.25-7) and 10 (8.25-12) respectively. Thirteen patients required invasive mechanical ventilation (IMV) and had a median PaO2/FiO2 ratio of 194 mmHg (IQR 173-213) after intubation. The 28-day survival was 100%, with 2 patients demising subsequently. The overall ICU mortality rate was 9.1% at the time of data censoring. In IMV survivors, length of IMV and ICU stay were 11 days (IQR 9-17.75) and 16 days (IQR 12-32) respectively.
CONCLUSION
Low COVID-19 ICU mortality was observed in our "pandemic-ready" ICU. This was achieved by having adequate surge capacity to facilitate early ICU admission and IMV, lung protective ventilation, and slow weaning. Being able to maintain clinical standards and evidence-based practices without having to resort to rationing contributed to better outcomes.

OBJECTIVE:
To study the significance of the level of soluble triggering receptor expressed on myeloid cells-1 (sTREM-1) in serum and bronchoalveolar lavage fluid (BALF), Acute Physiology and Chronic Health Evaluation II (APACHE II) score, and Sequential Organ Failure Assessment (SOFA) score in evaluating the conditions and prognosis of children with severe pneumonia.
METHODS:
A total of 76 children with severe pneumonia who were admitted from August 2017 to October 2019 were enrolled as the severe pneumonia group. According to the treatment outcome, they were divided into a non-response group with 34 children and a response group with 42 children. Ninety-four children with common pneumonia who were admitted during the same period of time were enrolled as the common pneumonia group. One hundred healthy children who underwent physical examination in the outpatient service during the same period of time were enrolled as the control group. The serum level of sTREM-1, APACHE II score, and SOFA score were measured for each group, and the level of sTREM-1 in BALF was measured for children with severe pneumonia. The correlation of the above indices with the severity and prognosis of severe pneumonia in children was analyzed.
RESULTS:
The severe pneumonia group had significantly higher serum sTREM-1 level, APACHEII score, and SOFA score than the common pneumonia group and the control group (P<0.05). For the children with severe pneumonia, the non-response group had significant increases in the levels of sTREM-1 in serum and BALF and SOFA score on day 7 after admission, while the response group had significant reductions in these indices, and there were significant differences between the two groups (P<0.05). Positive correlation was found between any two of serum sTREM-1, BALF sTREM-1, and SOFA score (P<0.05). APACHE II score was not correlated with serum sTREM-1, BALF sTREM-1, and SOFA score (P>0.05).
CONCLUSIONS
The level of sTREM-1 in serum and BALF and SOFA score can be used to evaluate the severity and prognosis of severe pneumonia in children.

OBJECTIVES: Although delirium is a common complication among patients hospitalized in intensive care units(ICUs), little is known about the roles that diagnostic and therapeutic procedures play in its development. This study investigates the procedure-related risk factors of delirium in ICU patients. METHODS: All the consecutive patients admitted to the ICU between June 2016 and May 2017 were routinely evaluated for delirium by psychiatrists. In total, 1156 patients met the inclusion criteria and were retrospectively analyzed. A multiple logistic regression analysis was conducted to investigate independent risk factors of delirium development while adjusting for other characteristics. RESULTS: The age, Acute Physiology and Chronic Health Evaluation (APACHE II) score, proportion of patients who had undergone an operation, and proportion of patients who were foley catheterized, mechanically ventilated, and physically restrained were higher in the delirium group. The multiple logistic regression analysis confirmed that the use of restraint was an independent risk factor of delirium (odds ratio : 10.006 ; 95% confidence interval : 6.120–16.360 ; p<0.001). The patient factors independently associated with delirium were an advanced age and a higher APACHE II score. The incidence of delirium was 15.3%. CONCLUSIONS: There is a high prevalence of delirium influenced by potentially harmful procedures in patients in ICU settings. The use of physical restraint had the strongest association with the development of delirium. These findings advocate the need to target procedure-related risk factors such as the use of restraints as preventive intervention measures for ICU delirium.

BACKGROUND: Although the frequency of respiratory viral infection in patients with pulmonary acute respiratory distress syndrome (ARDS) is not uncommon, clinical significance of the condition remains to be further elucidated. The purpose of this study was to compare characteristics and outcomes of patients with pulmonary ARDS infected with influenza and other respiratory viruses. METHODS: Clinical data of patients with pulmonary ARDS infected with respiratory viruses January 2014–June 2018 were reviewed. Respiratory viral infection was identified by multiplex reverse transcription–polymerase chain reaction (RT-PCR). RESULTS: Among 126 patients who underwent multiplex RT-PCR, respiratory viral infection was identified in 46% (58/126): 28 patients with influenza and 30 patients with other respiratory viruses. There was no significant difference in baseline and clinical characteristics between patients with influenza and those with other respiratory viruses. The use of extracorporeal membrane oxygenation (ECMO) was more frequent in patients with influenza than in those with other respiratory viruses (32.1% vs 3.3%, p=0.006). Co-bacterial pathogens were more frequently isolated from respiratory samples of patients with pulmonary ARDS infected with influenza virus than those with other respiratory viruses. (53.6% vs 26.7%, p=0.036). There were no significant differences regarding clinical outcomes. In multivariate analysis, acute physiology and chronic health evaluation II was associated with 30-mortality (odds ratio, 1.158; 95% confidence interval, 1.022–1.312; p=0.022). CONCLUSION: Respiratory viral infection was not uncommon in patients with pulmonary ARDS. Influenza virus was most commonly identified and was associated with more co-bacterial infection and ECMO therapy.
