Abstract Background: The triglyceride‑glucose (TyG) index is a reliable surrogate of insulin resistance and a marker for ischemic stroke (IS) incident. Whether the TyG index predicts stroke outcome remains uncertain. This study investigated the prognostic value of the TyG index in critically ill stroke patients.Methods: This was a retrospective observational study that included stroke patients, and all data were extracted from the eICU Collaborative Research Database. The TyG index was calculated as the ln (fasting glucose level [mg/dL] × triglyceride level [mg/dL]/2). The outcomes included the hospital and intensive care unit (ICU) death. Multivariate logistic regression was used to determine independent risk factors. The smoothing curves and forest plots were illustrated.Results: A total of 4570 eligible subjects were enrolled. The mean level of TyG index was 9.1 ± 0.7. The hospital and ICU mortality rate were 10.3% and 5.0% respectively. TyG index as a continuous variable was associated hospital mortality in univariate analysis (OR 1.723, 95% CI 1.524-1.948, P < 0.001), adjusted model 1 (OR 1.861, 95% CI 1637-2.116, P < 0.001) and adjusted model 2 (OR 2.543, 95% CI 1.588-4.073, P < 0.001). TyG was also associated ICU mortality in univariate analysis (OR 2.146, 95% CI 1.826-2.523, P < 0.001), adjusted model 1 (OR 2.183, 95% CI 1.847-2.580, P < 0.001), and adjusted model 2 (OR 2.672, 95% CI 1.376-5.188, P < 0.001). The smoothing curves observed a continuous linear association after adjusting all covariates both in hospital and ICU mortality. Subgroup analysis demonstrated TyG index was associated with increased risk of hospital and ICU death in critically ill IS (P < 0.05), but not in hemorrhage stroke (P > 0.05).Conclusion: The TyG index is a potential predictor for hospital and ICU mortality in critically ill stroke patients, especially in IS patients.

Abstract Background: It remains unclear whether the mean vancomycin trough concentration (VTC) derived from the entire course of therapy is of potential benefit for critically ill patients. This study was conducted to explore the association between mean serum VTC and mortality in intensive care units (ICUs).Methods: 3,364 adult patients with two or more VTC records after receiving vancomycin therapy in the eICU Collaborative Research Database were included in this multicenter retrospective cohort study. Mean VTC was estimated using all measured VTCs and investigated as a continuous and categorical variable. Patients were categorized into four groups according to mean VTC: <10, 10–15, 15–20, and >20 mg/L. Multivariable logistic regression and subgroup analyses were performed to investigate the relationship of mean VTC with mortality.Results: After adjusting for a series of covariates, logistic regression analyses indicated that mean VTC, as a continuous variable, was positively correlated with ICU (odds ratio, 1.042, 95% confidence interval, [1.017–1.068]) and hospital (1.025 [1.004–1.046]) mortalities. As a categorical variable, mean VTC at 10–15 mg/L failed to reduce ICU mortality (1.512 [0.849–2.694]). Moreover, mean VTCs of 15–20 and >20 mg/L were significantly associated with higher ICU mortality (1.946 [1.106–3.424]; 2.314 [1.296–4.132]) than mean VTC <10 mg/L. Mean VTCs of 10–15, 15–20, and >20 mg/L were not associated with increased hospital mortality (1.154 [0.766–1.739]; 1.342 [0.896–2.011]; 1.496 [0.981–2.281]). Similar results were observed in different Acute Physiology and Chronic Health Evaluation IV score or creatinine clearance subgroups.Conclusions: Increasing mean VTC showed no benefit regarding ICU and hospital mortalities in critically ill patients. Our results suggested that continuous VTC monitoring might not guarantee vancomycin efficacy for ICU patients.

Background: It remains unclear whether the mean vancomycin trough concentration (VTC) derived from the entire course of therapy is of potential benefit for critically ill patients. This study was conducted to explore the association between mean serum VTC and mortality in intensive care units (ICUs).Methods: 3,603 adult patients with two or more VTC records after receiving vancomycin treatment in the eICU Collaborative Research Database were included in this multicenter retrospective cohort study. Mean VTC was estimated using all measured VTCs and investigated as a continuous and categorical variable. Patients were categorised into four groups according to mean VTC: &lt;10, 10–15, 15–20, and &gt;20 mg/L. Multivariable logistic regression and subgroup analyses were performed to investigate the relationship of mean VTC with mortality.Results: After adjusting for a series of covariates, logistic regression analyses indicated that mean VTC, as a continuous variable, was positively correlated with ICU (odds ratio, 1.038, 95% confidence interval, [1.014–1.063]) and hospital (1.025 [1.005–1.046]) mortalities. As a categorical variable, mean VTC of 10–15 mg/L was not associated with reduced ICU (1.705 [0.975–2.981]) and hospital (1.235 [0.829–1.841]) mortalities. Mean VTC of 15–20 mg/L was not correlated with a lower risk of hospital mortality (1.370 [0.924–2.029]). Moreover, mean VTCs of 15–20 and &gt;20 mg/L were significantly associated with higher ICU mortality (1.924 [1.111–3.332]; 2.428 [1.385–4.258]), and mean VTC of &gt;20 mg/L with higher hospital mortality (1.585 [1.053–2.387]) than mean VTC of &lt;10 mg/L. Similar results were observed in patients with different Acute Physiology and Chronic Health Evaluation IV score, creatinine clearance, age, and body mass index subgroups.Conclusion: Mean VTC was not associated with reduced ICU/hospital related mortality. Our results suggested that VTC monitoring might not guarantee vancomycin efficacy for ICU patients.

<b><i>Introduction:</i></b> We aimed to identify different trajectories of fluid balance (FB) and investigate the effect of FB trajectories on clinical outcomes in intensive care unit (ICU) patients with acute kidney injury (AKI) and the dose-response association between fluid overload (FO) and mortality. <b><i>Methods:</i></b> We derived data from the Beijing Acute Kidney Injury Trial (BAKIT). A total of 1,529 critically ill patients with AKI were included. The primary outcome was 28-day mortality, and hospital mortality, ICU mortality and AKI stage were the secondary outcomes. A group-based trajectory model was used to identify the trajectory of FB during the first 7 days. Multivariable logistic regression was performed to examine the relationship between FB trajectories and clinical outcomes. A logistic regression model with restricted cubic splines was used to examine the dose relationship between FO and 28-day mortality. <b><i>Results:</i></b> Three distinct trajectories of FB were identified: low FB (1,316, 86.1%), decreasing FB (120, 7.8%), and high FB (93, 6.1%). Compared with low FB, high FB was associated with increased 28-day mortality (odds ratio [OR] 1.94, 95% confidence interval [CI] 1.17–3.19) and AKI stage (OR 2.04, 95% CI 1.23–3.37), whereas decreasing FB was associated with a reduction in 28-day mortality by approximately half (OR 0.53, 95% CI 0.32–0.87). Similar results were found for the outcomes of ICU mortality and hospital mortality. We observed a J-shaped relationship between maximum FO and 28-day mortality, with the lowest risk at a maximum FO of 2.8% L/kg. <b><i>Conclusion:</i></b> Different trajectories of FB in critically ill patients with AKI were associated with clinical outcomes. An FB above or below a certain range was associated with an increased risk of mortality. Further studies should explore this relationship and search for the optimal fluid management strategies for critically ill patients with AKI.

Objective We aimed to compare the efficacy and risks of proton pump inhibitor (PPI) versus histamine-2 receptor blocker (H2B) use for stress ulcer prophylaxis (SUP) in critically ill patients with sepsis and risk factors for gastrointestinal bleeding (GIB). Methods In this retrospective cohort study, we used the Medical Information Mart for Intensive Care III Clinical Database to identify critically ill adult patients with sepsis who had at least one risk factor for GIB and received either an H2B or PPI for ≥48 hours. Propensity score matching (PSM) was conducted to balance baseline characteristics. The primary outcome was in-hospital mortality. Results After 1:1 PSM, 1056 patients were included in the H2B and PPI groups. The PPI group had higher in-hospital mortality (23.8% vs. 17.5%), GIB (8.9% vs. 1.6%), and pneumonia (49.6% vs. 41.6%) rates than the H2B group. After adjusting for risk factors of GIB and pneumonia, PPI use was associated with a 1.28-times increased risk of in-hospital mortality, 5.89-times increased risk of GIB, and 1.32-times increased risk of pneumonia. Conclusions Among critically ill adult patients with sepsis at risk for GIB, SUP with PPIs was associated with higher in-hospital mortality and higher risk of GIB and pneumonia than H2Bs.

Abstract Background The clinical efficiency of routine oxygen therapy is uncertain in patients with acute heart failure (AHF) who do not have hypoxemia. The aim of this study was to investigate the association between oxygen therapy and clinical outcomes in normoxemic patients hospitalized with AHF using real-world data. Methods Normoxemic patients diagnosed with AHF on ICU admission from the electronic ICU (eICU) Collaborative Research Database were included in the current study, in which the study population was divided into the oxygen therapy group and the ambient-air group. Propensity score matching (PSM) was applied to create a balanced covariate distribution between patients receiving supplemental oxygen and those exposed to ambient air. Linear regression and logistic regression models were performed to assess the associations between oxygen therapy and length of stay (LOS), and all-cause in-hospital as well as ICU mortality rates, respectively. A series of sensitivity and subgroup analyses were conducted to further validate the robustness of our findings. Results A total of 2922 normoxemic patients with AHF were finally included in the analysis. Overall, 42.1% (1230/2922) patients were exposed to oxygen therapy, and 57.9% (1692/2922) patients did not receive oxygen therapy (defined as the ambient-air group). After PSM analysis, 1122 pairs of patients were matched: each patient receiving oxygen therapy was matched with a patient without receiving supplemental oxygen. The multivariable logistic model showed that there was no significant interaction between the ambient air and oxygen group for all-cause in-hospital mortality [odds ratio (OR) 1.30; 95% confidence interval (CI) 0.92–1.82; P = 0.138] or ICU mortality (OR 1.39; 95% CI 0.83–2.32; P = 0.206) in the post-PSM cohorts. In addition, linear regression analysis revealed that oxygen therapy was associated with prolonged ICU LOS (OR 1.11; 95% CI 1.06–1.15; P <  0.001) and hospital LOS (OR 1.06; 95% CI 1.01–1.10; P = 0.009) after PSM. Furthermore, the absence of an effect of supplemental oxygen on mortality was consistent in all subgroups. Conclusion Routine use of supplemental oxygen in AHF patients without hypoxemia was not found to reduce all-cause in-hospital mortality or ICU mortality.

Abstract Background Cirrhosis can be complicated by electrolyte abnormalities, but the major focus has been concentrated on the clinical significance of serum sodium levels. Emerging studies have identified hypochloremia as an independent prognostic marker in patients with chronic heart failure and chronic kidney disease. The aim of this study was to investigate whether serum chloride levels were associated with mortality of critically ill cirrhotic patients. Methods Critically ill cirrhotic patients were identified from the Multi-parameter Intelligent Monitoring in Intensive Care III Database. The primary outcome was ICU mortality. Logistic regression was used to explore the association between serum chloride levels and ICU mortality. The area under the receiver operating characteristic curves (AUC) was used to assess the performance of serum chloride levels for predicting ICU mortality. Results A total of 1216 critically ill cirrhotic patients were enrolled in this study. The overall ICU mortality rate was 18.8%. Patients with hypochloremia had a higher ICU mortality than those with non-hypochloremia (34.2% vs. 15.8%; p < 0.001). After multivariable risk adjustment for age, gender, ethnicity, chloride, sodium, Model for End-stage Liver Disease score, Sequential Organ Failure Assessment score, Elixhauser comorbidity index, mechanical ventilation, vasopressors, renal replacement therapy, acute kidney injury, hemoglobin, platelet, and white blood cell, serum chloride levels remained independently associated with ICU mortality (OR 0.94; 95% CI 0.91–0.98; p = 0.002) in contrast to serum sodium levels, which were no longer significant (OR 1.03; 95% CI 0.99–1.08; p = 0.119). The AUC of serum chloride levels (AUC, 0.600; 95% CI 0.556–0.643) for ICU mortality was statistically higher than that of serum sodium levels (AUC, 0.544; 95% CI 0.499–0.590) (p < 0.001). Conclusions In critically ill cirrhotic patients, serum chloride levels are independently and inversely associated with ICU mortality, thus highlighting the prognostic role of serum chloride levels which are largely overlooked.

Introduction : Age is the single most important risk factor for stroke and an estimated 75% of all strokes occur in people >65 years of age. In addition, adults >75 years’ experience more hospitalization stays and higher mortality rates with an estimated 50% in the occurrence of all strokes. Several comorbidities have been linked to an increased risk and severity of acute ischemic stroke (AIS). How these factors differentially contribute to the severity of stroke in patients ages >65 and <75 as well as those ≥75 is not known. In this study, we aim to investigate how age, coupled with various clinical risk factors, affects AIS severity within these two age categories. Methods : This retrospective data analysis study was conducted using the data collected from the PRISMA Health Stroke Registry between 2010 and 2016. Baseline clinical and demographic data for patients ages >65 and <75 as well as those ≥75 was analyzed using univariate analysis. Receiver operating characteristic (ROC) curve analysis and multivariate regression models were used to examine the association of specific baseline risk factors or comorbidities associated with worsening or improving neurologic functions. The primary functions were risk factors associated with improving or worsening neurologic outcome in each age category. Results : Adjusted multivariate analysis showed that AIS population of patients >65 and <75 experiencing heart failure (OR = 4.398, 95% CI, 3.912 – 494.613, P = 0.002) and elevated HDL levels (OR = 1.066, 95% CI, 1.009 – 1.126, P = 0.024) trended towards worsening neurologic functions while patients experiencing obesity (OR = 0.177, 95% CI, 0.041 – 0.760, P = 0.020) exhibited improving neurologic functions. For the patients ≥75 years of age, direct admission (OR = 0.270, 95% CI, 0.085 – 0.856, P = 0.026) was associated with improvement of patients treated in the telestroke. Conclusions : Age is a strong risk factor for AIS, and aged stroke patients have higher morbidity and worsening functional recovery than younger patients. In this study, we observed differences in stroke risk factor profiles for >65 and <75 and ≥75 age categories. Heart failure and elevated HDL levels were significantly associated with worsening neurologic functions among AIS for patients aged >65 and <75. Obese patients and individuals ≥75 years who were directly admitted were most likely to exhibit improving neurologic functions. Most importantly, findings from this study reveal specific risk factors that can be managed to improve the care in older stroke patients treated in the telestroke network.

Introduction: An overwhelming benefit from endovascular treatment (EVT) of acute ischemic stroke (AIS) has been shown in recent trials, making it the new evidence-based standard of care for ischemic stroke due to anterior circulation large vessel occlusion. We sought to determine usage, safety and efficacy of EVT in patients ≥80 years of age. Methods: Using GWTG stroke registry data from MGH and UAMS, we analyzed 7,505 consecutive stroke admissions from 01/2009 - 06/2016. Univariate analysis was carried out to compare AIS patients < 80 vs. those ≥ 80yr. Results: Of the total 7,505 AIS patients, 3,722 presented within 12 hr of last known well and of these 334 (334/3722, 9%) underwent EVT. The majority of AIS patients undergoing EVT were younger than 80yr of age (264/334, 79%). Of the patients who underwent EVT, younger patients were more often male, Caucasian, and had stroke risk factors of atrial fibrillation, CAD, hypertension and smokers. The two groups were similar in NIHSS, initial clinical presentation, modified pre-stroke Rankin scale of ≤ 3, and initiation of tPA as a drip and ship or stroke center front-door administration. Higher rates of pneumonia were observed in younger patients while rates of sICH were similar. Younger patients were more often discharged to home/inpatient rehabilitation facility. On univariate analysis, in-hospital mortality was significantly higher in patients ≥ 80yr [Unadj. OR 2.50 (1.24, 5.03), p=0.01], however the strength of the association attenuated substantially after adjusting for significant covariates [Adj. OR 2.34 (0.99, 5.47), p=0.05] (Table). Conclusion: Elderly stroke patients are largely excluded from clinical trials and data are limited on the effectiveness of EVT in this cohort. Our results showed that rate of sICH and adjusted in-hospital mortality was not statistically different between those < 80yr vs. ≥ 80yr. Further studies are needed to explore the functional outcome of the elderly stroke patients undergoing EVT.

There is limited evidence for the association between malnutrition and hospital mortality as well as Intensive Care Unit length-of-stay (ICU-LOS) in critically ill patients. We aimed to examine the aforementioned associations by conducting a prospective cohort study in an ICU of a Singapore tertiary hospital. Between August 2015 and October 2016, all adult patients with &ge;24 h of ICU-LOS were included. The 7-point Subjective Global Assessment (7-point SGA) was used to determine patients&rsquo; nutritional status within 48 hours of ICU admission. Multivariate analyses were conducted in two ways: 1) presence versus absence of malnutrition, and 2) dose-dependent association for each 1-point decrease in the 7-point SGA. There were 439 patients of which 28.0% were malnourished, and 29.6% died before hospital discharge. Malnutrition was associated with an increased risk of hospital mortality [adjusted-RR 1.39 (95%CI: 1.10&ndash;1.76)], and this risk increased with a greater degree of malnutrition [adjusted-RR 1.09 (95%CI: 1.01&ndash;1.18) for each 1-point decrease in the 7-point SGA]. No significant association was found between malnutrition and ICU-LOS. Conclusion: There was a clear association between malnutrition and higher hospital mortality in critically ill patients. The association between malnutrition and ICU-LOS could not be replicated and hence requires further evaluation.
