Independent Predictor Of Short-term Mortality Research Articles

The Predictive Role of Lactate in the Emergency Department in Patients with Severe Dyspnea.

An accurate identification of patients at the need for prioritized diagnostics and care are crucial in the emergency department (ED). Blood gas (BG) analysis is a widely available laboratory test, which allows to measure vital parameters, including markers of ventilation and perfusion. The aim of our analysis was to assess whether blood gas parameters in patients with dyspnea at an increased risk of respiratory failure admitted to the ED can predict short-term outcomes. The study group eventually consisted of 108 patients, with available BG analysis. The clinical and laboratory parameters were retrospectively evaluated, and three groups were distinguished-arterial blood gas (ABG), venous blood gas (VBG), and mixed blood gas. The primary endpoint was short-term, all-cause mortality during the follow-up of median (quartile 1-quartile 3) 2 (1-4) months. The independent risk factors for mortality that could be obtained from blood gas sampling were evaluated. The short-term mortality was 35.2% (38/108). Patients who died were more frequently initially assigned to the red triage risk group, more burdened with comorbidities, and the median SpO2 on admission was significantly lower than in patients who survived the follow-up period. In the multivariable analysis, lactate was the strongest independent predictor of death, with 1 mmol/L increasing all-cause mortality by 58% in ABG (95% CI: 1.01-2.47), by 80% in VBG (95% CI: 1.13-2.88), and by 68% in the mixed blood gas analysis (95% CI: 1.22-2.31), what remained significant in VBG and mixed group after correction for base excess. In each group, pH, pO2, and pCO2 did not predict short-term mortality. In patients admitted to the ED due to dyspnea, at risk of respiratory failure, lactate levels in arterial, venous, and mixed blood samples are independent predictors of short-term mortality.

The predictive value of the HALP score for no-reflow phenomenon and short-term mortality in patients with ST-elevation myocardial infarction

ABSTRACT Objective ST-elevation myocardial infarction (STEMI) is a medical emergency demanding immediate intervention, and primary percutaneous coronary intervention (pPCI) is the standard of care for this condition. While PCI has proven highly effective, a subset of patients experience the devastating no-reflow phenomenon, and some face increased short-term mortality. The Hemoglobin, Albumin, Lymphocyte, and Platelet (HALP) score, a novel biomarker-based tool, has recently surfaced as an innovative predictor of these adverse outcomes. This study aims to investigate the groundbreaking findings that designate a low HALP score as a robust risk factor for no-reflow and short-term mortality in STEMI patients. Methods 1817 consecutive STEMI patients who underwent pPCI were included in this retrospective study, and the patients were divided into two groups according to whether no-reflow developed or not, and the HALP scores of the groups were compared. In addition, short-term mortality was compared between the study groups according to their HALP score values. The predictive ability of the HALP score for no-reflow was evaluated using a receiver operating characteristic curve. Results No-reflow developed in 198 (10.1%) of the patients included in the study. HALP score value was found to be significantly lower in the no-reflow group (27 ± 13 vs 47 ± 24, p < 0.001). After multivariable adjustment, the HALP score was an independent predictor of no-reflow (OR, 0.923, 95% CI, 0.910–0.935, p < 0.001). Furthermore, the HALP score showed good discrimination for no-reflow (AUC, 0.771, 95% CI, 0.737–0.805, p < 0.001). In addition, HALP score was determined to be an independent predictor for short-term mortality (HR, 0.955, 95% CI, 0.945–0.966, p < 0.001). Conclusions HALP score can independently predict the development of no-reflow and short-term mortality in STEMI patients undergoing pPCI.

Abstract TP262: Trends, Odds, Burdens and Outcomes of Metabolically Healthy Obesity in Stroke Related Hospitalizations of Elderly Patients - A Nationwide Analysis, 2016-2019

Background: Obesity has been associated with an increase in the risk of stroke and poor outcomes. Meanwhile, Metabolically healthy obesity (MHO) trends are understudied in association with stroke. In this study, we aim to analyze the MHO trends and outcomes with respect to Stroke. Methods: We queried the National Inpatient Sample (2016-2019) to identify Stroke hospitalizations in the elderly population (%E2%89%A565 years) with vs without MHO by using ICD-10 codes after excluding patients with Hypertension, analyze, and Diabetes Mellitus. Patients were categorized into a metabolically healthy obese MHO+ve cohort, BMI&gt; 30, and MHO-ve cohort, BMI&lt;30. Trends, demographics, comorbidities, and outcomes were then compared between the two cohorts. Results: Overall Prevalence of stroke was higher in the MHO-ve cohort (2.4% vs 1.4% p&lt;0.001) compared to the MHO+ve cohort. MHO-ve cohort often consisted of higher median age (78 vs 73 years), Males (48.2% vs 36.4%), Hispanics (5.1% vs 4.7%), whites (83.8% vs 82.3%), Asians (2.4% vs 1.1%) vs MHO +ve cohort (p&lt;0.001). The rate of death (15.9% vs 14.4%), Home health care requirements (16.6% vs 12.4%) was also higher in the MHO-ve cohort vs MHO+ve cohort. Conversely, the MHO+ve cohort had higher rates of smokers, Prior MI, Hypothyroidism, CKD, and OSA in comparison to the MHO-ve cohort. Univariate and Multivariate regression analysis adjusted for confounders did not show any significant association between Stroke and MHO. Conclusion: Excluding other cardiovascular disease risk factors such as hypertension, diabetes mellitus, and hyperlipidemia, the non-significant difference in in-hospital mortality between elderly stroke patients with vs without MHO suggests that MHO might not be a significant independent predictor of short-term mortality. Other factors likely influence this relationship. Further research is warranted for the investigation of the factors influencing the absence of a relationship between stroke and MHO.

LncRNA HOTTIP as a diagnostic biomarker for acute respiratory distress syndrome in patients with sepsis and to predict the short-term clinical outcome: a case-control study

BackgroundThe present research aims to investigate the clinical diagnostic value of LncRNA HOXA distal transcript antisense RNA (HOTTIP) in acute respiratory distress syndrome (ARDS) of sepsis and its predictive significance for mortality.MethodsOne hundred eighteenth patients with sepsis and 96 healthy individuals were enrolled. RT-qPCR to examine HOTTIP levels. The incidence of ARDS and death was recorded. The diagnostic significance of HOTTIP in sepsis ARDS was examined using ROC and logistic regression analysis. The correlation between HOTTIP and disease severity was evaluated using Pearson’s coefficients. Kaplan-Meier analysis and COX regression were employed to examine the predictive significance of mortality. Validation of HOTTIP target miRNA by dual-luciferase assay.ResultsHOTTIP was persistently up-regulated in patients with ARDS sepsis than in patients without ARDS patients (P < 0.05). HOTTIP was a risk factor for the development of ARDS, which could be diagnosed in ARDS patients from non-ARDS patients (AUC = 0.847). Both the SOFA score (r = 0.6793) and the APACHE II score (r = 0.6384) were positively correlated with the HOTTIP levels. Furthermore, serum HOTTIP was an independent predictor of short-term mortality (HR = 4.813. 95%CI: 1.471–15.750, P = 0.009) and noticeably predicted the occurrence of short-term death (log rank = 0.020). miR-574-5p, a target miRNA for HOTTIP, was reduced in patients with sepsis ARDS and negatively correlated with HOTTIP.ConclusionsThe presence of HOTTIP serves as a diagnostic biomarker for the occurrence of ARDS, exhibits correlation with disease severity, and provides predictive value of short-term mortality in sepsis patients. HOTTIP may be involved in ARDS progression by targeting miR-574-5p.

PB0860 Von Willebrand Factor is an Independent Predictor of Short-Term Mortality in Acutely Ill Patients with Cirrhosis

PB0860 Von Willebrand Factor is an Independent Predictor of Short-Term Mortality in Acutely Ill Patients with Cirrhosis

Von Willebrand factor is an independent predictor of short-term mortality in acutely ill patients with cirrhosis.

Levels of von Willebrand factor (VWF) are elevated in patients with cirrhosis, and correlate well with disease severity. In patients with decompensated cirrhosis (DC), plasma VWF is associated with mortality. The value of VWF in predicting short-term mortality risk in patients with acute-on-chronic liver failure (ACLF) is, however, unclear. We included patients with DC (n = 111) and ACLF (n = 105). We measured VWF levels and correlated these with other laboratory parameters and prediction models for mortality. Also, we assessed the predictive value of VWF in the prediction of 90- and 30-day mortality in patients with DC and ACLF, respectively, and compared this to the predictive value of clinically used prediction models. Finally, we determined the optimal cut-off value for VWF in patients with ACLF. Sixteen of 111 (14%) patients with DC and 35 of 105 (33%) with ACLF died within 90 and 30 days, respectively. VWF was associated with mortality and correlated closely with other prediction models. In patients with ACLF, VWF levels had a discrimination for 30-day mortality comparable with these models and accurately identified ACLF patients with high 30-day mortality risk. Levels of VWF associate closely with risk of mortality in patients with DC and ACLF, and may have predictive utility as a laboratory marker of prognosis. Further research is warranted to assess the additional value of VWF in the prediction of mortality and associated complications in chronic liver failure syndromes.

Association between serum anion gap and all-cause mortality in patients with acute myocardial infarction: A retrospective study based on MIMIC-IV database

BackgroundAlthough previous studies have reported that many biomarkers can determine the prognosis of patients with acute myocardial infarction (AMI), serum anion gap (AG) has not been well studied. We aimed to investigate the association between serum AG and mortality in patients with AMI. MethodsAdult patients first admitted to the ICU and diagnosed with AMI from 2008 to 2019 in the MIMIC-IV database were included. Patients were divided into the survival and non-survival groups based on 30-day and 90-day outcomes. According to the AG value (15.12 mmol/L) with a hazard ratio of 1 in the restricted cubic spline (RCS) analysis, patients were further divided into high and low AG groups. The Kaplan-Meier survival curve was plotted, and all-cause mortality was compared between the high and low groups using the log-rank test. Multivariate Cox regression analysis and RCS analysis were constructed to assess the relationship between AG and recent all-cause mortality in patients with AMI. Results4446 patients were enrolled. The 30-day and 90-day mortality rates in the high AG group (25.53%, 31.75%) were higher than that in the low AG group (9.73%, 14.01%, P < 0.001) independently. The Kaplan-Meier curve showed that the 30-day and 90-day cumulative survival rates were lower in the high AG group than that in the low AG group (P < 0.001). RCS analysis showed that there was a non-linear relationship between AG and the risk of 90-day all-cause mortality in patients with AMI (χ2 = 18.680 P < 0.001). When AG was 15.12 mmol/L, its HR was about 1. Multivariable Cox regression analysis confirmed that increased AG was associated with higher 30-day and 90-day mortality. ConclusionElevated serum AG (≥15.12 mmol/L) is an independent predictor for short-term mortality in patients with AMI, and it may provide a basis for clinicians to identify patients with poor prognosis as early as possible.

Prognostic value of TCBI for short-term outcomes in ATAD patients undergoing surgery.

Nutritional status has been reported to be associated with the prognosis of cardiovascular diseases. The study aimed to investigate the prognostic value of Triglycerides-total Cholesterol-Body weight-Index (TCBI) for short-term mortality in acute type A aortic dissection (ATAD) patients undergoing surgery. Totally, the data of 290 ATAD patients undergone surgery were, retrospectively, analyzed. After logistic regression analysis, TCBI was identified as an independent predictor of short-term mortality in ATAD surgery. The development of receive operating characteristic (ROC) curve demonstrated that TCBI (AUC = 0.745, P < 0.001) could provide well prognostic value for short-term mortality. Accordingly, the optimal cut-off value was identified as 883.5 and patients were divided into high TCBI (> 883.5) and low TCBI (≤ 883.5) groups. Furthermore, Kaplan-Meier analysis illustrated that short-term mortality increased significantly in the low TCBI group than in the high TCBI group (P < 0.0001). In addition, the incidence of postoperative renal failure was also elevated in the low TCBI group (P = 0.0011). Malnutrition by preoperative TCBI presented strong prognostic value for patients following ATAD surgery. And TCBI could be applied for risk stratification and therapeutic strategy-making in ATAD.

Prealbumin as a Predictor of Short-Term Prognosis in Patients with HBV-Related Acute-on-Chronic Liver Failure.

Hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF) is a serious medical condition with a high short-term mortality rate, making accurate prognostic assessment essential for informed clinical decision-making. In this study, we aimed to develop a simple and effective prognostic model for predicting short-term mortality in patients with HBV-ACLF. To achieve our objective, we enrolled both a cross-sectional cohort (n = 291) and a retrospective cohort (n = 185) in this study. We collected laboratory and clinical data from these cohorts and performed univariate and multivariate logistic regression analyses to identify independent predictors of short-term mortality. Subsequently, we developed a novel prognostic score for HBV-ACLF, which was validated and assessed using receiver operating characteristic (ROC) curve analysis to determine its performance. Our analysis revealed that the admission prealbumin (PAB) level was a robust independent predictor of 30-day mortality, with an area under the receiver operating characteristic (AUROC) of 0.760. Moreover, we developed the HIAPP score, a prognostic-score model based on PAB. The HIAPP score was significantly lower in survivors compared to non-survivors (-2.80±0.21 vs 0.97±0.41, P < 0.001). The HIAPP score's AUROC value was 0.899, which was found to be superior to the MELD score (AUROC = 0.795) and the CLIF-C ACLF score (AUC =0.781) and comparable to the COSSH-ACLF II score (AUC =0.825) for predicting 30-day mortality. These findings were also validated in a separate cohort, further supporting the utility of the HIAPP score as a prognostic tool for HBV-ACLF patients. Our study identifies the admission PAB level as a simple and valuable predictive index for 30-day mortality in HBV-ACLF patients. Furthermore, the HIAPP score, which incorporates PAB, PLT, INR, HE, and age, is an easy-to-use and pragmatic prognostic score in predicting short-term mortality.

Reduced Angiopoietin Factor 2 Levels Are Correlated with Better Cardiac Function and Prognosis in Valvular Heart Disease.

There are few circulating biomarkers for valvular heart disease. Angiopoietin (Ang) 1, Ang2, and vascular endothelial growth factor are important inflammation-associated cytokines. The aim of this study was to investigate the clinical significance and association of Ang1, Ang2, and vascular endothelial growth factor in valvular heart disease. This is a retrospective study; a total of 62 individuals (valvular heart disease patients [n=42] and healthy controls [n=20]) were included. Plasma levels of Ang1, Ang2, and vascular endothelial growth factor were detected by enzyme-linked immunosorbent assays. We retrospectively collected the baseline characteristics and short-term outcomes; logistic regression was performed to identify predictor for short-term mortality. Ang2 was significantly decreased in the valvular heart disease group compared with the healthy control group (P=0.023), while no significant difference was observed in the Ang1 and vascular endothelial growth factor levels. The Ang2 level of New York Heart Association (NYHA) I/II patients - but not NYHA III/IV patients - was significantly decreased compared with that of healthy control individuals (NYHA I/II: P=0.017; NYHA III/IV: P=0.485). Univariable logistic regression analysis indicated that Ang2 was a significant independent predictor for short-term mortality (odds ratio 18.75, P=0.033, 95% confidence interval 8.08-102.33). Ang1 was negatively correlated with Ang2 (P=0.032, Pearson's correlation coefficient =-0.317) and was positively correlated with vascular endothelial growth factor (P=0.019, Pearson's correlation coefficient = 0.359). Ang2 might serve as a therapeutic and prognostic target for valvular heart disease.

RDW and pro-BNP in predicting short-term mortality in geriatric patients presenting to the emergency department with acute decompensated heart failure

To reveal the ability of Red cell Distribution Width (RDW) to predict short-term mortality in geriatric patients presenting to the emergency department with acute heart failure and compare the results with pro B-type Natriuretic Peptide (pro-BNP). This prospective cohort study was conducted to evaluate the data of patients admitted to the emergency department between August 15th, 2021, and November 15th, 2021. The study population enrolled volunteers aged 65 years and over, who presented with acute heart failure signs and symptoms. Demographics, vital parameters, and laboratory parameters were noted. A total of 424 patients were included in the study. The 30 day-mortality rate of the study cohort was 14.4%. Older age, active malignancy, RDW, C-reactive protein, blood urea nitrogen, and pro-BNP were early independent predictors of short-term mortality. pro-BNP was a better predictor than RDW with a greater area under the curve value (0.841 versus 0.752, p=0.045, DeLong equality test). The created multivariate regression model was able to detect the risk of shortterm mortality with high accuracy (area under the curve: 0.943, accuracy: 0.936, sensitivity: 98.1, specificity: 67.2, p&lt;0.001). Initial RDW and pro-BNP were significantly higher in the mortality group among the geriatric patients with acute decompensated heart failure presenting to the emergency department, and pro- BNP was found to be a better predictor of mortality than RDW. RDW presents as a promising hematological marker that aids in the prognosticating short-term mortality in this patient population.

A new marker of short-term mortality and poor outcome in patients with acute ischemic stroke: Mean platelet volume-to-lymphocyte ratio.

Background:The mean platelet volume-to-lymphocyte ratio (MPVLR), as a novel marker of thrombosis and inflammation, has been demonstrated to be closely linked to poor cardiovascular disease prognosis. However, the correlation between MPVLR and acute ischemic stroke (AIS) remains unclear. This study, therefore, aimed to clarify the relationship between MPVLR and the short-term prognosis of AIS.Methods:A total of 315 patients with first-time AIS diagnoses were recruited and divided into 3 groups based on the tri-sectional quantiles for MPVLR on admission: group 1 (N = 105) with a MPVLR ≤ 4.93, group 2 (N = 105) with a MPVLR of 4.94 to 7.21, and group 3 (N = 105) with a MPVLR ≥ 7.22. All patients were followed-up for 3 months, and death within 3 months was defined as the endpoint. Baseline characteristics, stroke severity, and functional outcomes were evaluated.Results:The Spearman’s correlation coefficient test showed that MPVLR was significantly positively correlated with the National Institutes of Health Stroke Scale score (R = 0.517, P < .001). Multivariate analysis revealed that MPVLR was an independent predictor of both short-term mortality (adjusted odds ratio [OR] 1.435, P < .001) and poor outcome (adjusted OR 1.589, P < .001). The receiver operating characteristic (ROC) curve analysis showed that the best cutoff value of MPVLR for short-term mortality and poor outcome were 6.69 (sensitivity: 86.4%, specificity: 68.6%) and 6.38 (sensitivity: 78.8%, specificity: 72.3%), respectively.Conclusions:MPVLR on admission was positively associated with stroke severity. An elevated MPVLR is an independent predictor of short-term mortality and poor outcome after AIS.

The association between age, troponin level, and mortality in patients hospitalised with acute pulmonary embolism (NIHR Health Informatics Collaborative TROP-PE study)

Abstract Background A positive cardiac troponin (cTn) is an independent predictor of short-term mortality in individuals presenting with acute pulmonary embolism (PE). However, there is limited evidence regarding the impact age has on the association between cTn levels and mortality in patients with PE. Purpose The aim of our study was to investigate the relationship between cTn level, age, and all-cause mortality, in hospitalised patients diagnosed with an acute PE. Methods A retrospective cohort study using the National Institute for Health Research Health Informatics Collaborative Cardiovascular dataset of all consecutive patients who had a troponin measured at five hospitals between 2010 and 2017. Patients admitted to hospital with a primary diagnosis of PE with at least one cTn measurement were included. We modelled the relation between peak troponin level and all-cause mortality using multivariable adjusted restricted cubic spline Cox regression analyses. Effect estimates were adjusted for age, gender, high-sensitivity troponin assay, C-reactive protein, haemoglobin, platelet count, white cell count, creatinine, sodium, potassium, diabetes, hypertension, hypercholesterolaemia, acute coronary syndrome, atrial fibrillation, heart failure, acute kidney injury, chronic kidney disease, obstructive lung disease, inflammatory disorders, pneumonia and malignancy. The peak cTn level (highest level measured), standardised to the upper limit of normal (ULN), was used for all analyses. Results 1,477 patients with at least one cTn measurement and a diagnosis of acute PE were included. During a median follow-up of 34.8 months, there were 290 (19.6%) deaths. Elevated cTn (&amp;gt;1xULN) was associated with a hazard ratio (HR) of 3.29 (95% confidence interval [CI] 1.95–5.53) for 30-day mortality and 2.12 (95% CI 1.63–2.75) for 3-year mortality. Higher cTn levels were progressively associated with a higher mortality risk, reaching a maximum HR of 2.59 (95% CI 1.64–4.09) at 141xULN (Figure 1). Younger patients (&amp;lt;55 years), compared with those aged over 55, had the highest 3-year HR associated with a positive cTn of 2.94 (95% CI 1.48–5.82) despite having the lowest troponin levels (mean 7.01xULN) on admission (Figure 2). Conclusion Elevated cTn, at all ages, is associated with an increased mortality risk in patients presenting with PE, with increasing cTn levels conferring a progressively worse long-term prognosis. Elevated cTn, no matter how small, needs to be taken seriously, particularly in young patients with an acute PE.

Pneumatosis intestinalis in abdominal CT: predictors of short-term mortality in patients with clinical suspicion of mesenteric ischemia

PurposePneumatosis intestinalis (PI) in the bowel wall demonstrated in computed tomography (CT) of the abdomen is unspecific and its prognostic relevance remains poorly understood. The purpose of this study was to identify predictors of short-term mortality in patients with suspected mesenteric ischemia who were referred to abdominal CT and showed PI.MethodsIn this retrospective, IRB-approved, single-centre study, CT scans and electronic medical records of 540 patients who were referred to abdominal CT with clinical suspicion of mesenteric ischemia were analysed. 109/540 (20%) patients (median age 66 years, 39 females) showed PI. CT findings were correlated with surgical and pathology reports (if available), with clinical and laboratory findings, and with patient history. Short-term outcome was defined as survival within 30 days after CT.ResultsPI was found in the stomach (n = 6), small bowel (n = 65), and colon (n = 85). Further gas was found in mesenteric (n = 54), portal (n = 19) and intrahepatic veins (n = 36). Multivariate analysis revealed that PI in the colon [odds ratio (OR) 2.86], elevated blood AST levels (OR 3.00), and presence of perfusion inhomogeneities in other abdominal organs (OR 3.38) were independent predictors of short-term mortality. Surgery had a positive effect on mortality (88% lower likelihood of mortality), similar to the presence of abdominal pain (65% lower likelihood).ConclusionsOur study suggests that in patients referred for abdominal CT with clinical suspicion of mesenteric ischemia, location of PI in the colon, elevation of blood AST, and presence of perfusion inhomogeneities in parenchymatous organs are predictors of short-term mortality.Graphical abstract

Admission Dehydration Status Portends Adverse Short-Term Mortality in Patients with Spontaneous Intracerebral Hemorrhage.

The impact of dehydration at admission of patients with spontaneous intracerebral hemorrhage (ICH) on short-term mortality remains ambiguous due to scarce data. All of the consecutive patients with spontaneous ICH, who were referred to our neurovascular center in 2018/19, were assessed for hydration status on admission. Dehydration was defined by a blood urea-to-creatinine ratio > 80. In a cohort of 249 patients, 76 patients (31%) were dehydrated at the time of admission. The following factors were significantly and independently associated with increased 30-day mortality in multivariate analysis: “signs of cerebral herniation” (p = 0.008), “initial midline shift > 5 mm” (p < 0.001), “ICH score > 3” (p = 0.007), and “admission dehydration status” (p = 0.007). The results of the present study suggest that an admission dehydration status might constitute a significant and independent predictor of short-term mortality in patients with spontaneous ICH.

Histologic Changes in Core-Needle Liver Biopsies From Patients With Acute-on-Chronic Liver Failure and Independent Histologic Predictors of 28-Day Mortality.

The histologic features in patients with acute-on-chronic liver failure (ACLF) are evolving, and histologic indicators of patients' poor prognosis are not yet fully established. To evaluate the independent histologic predictors of 28-day mortality in ACLF patients on core-needle liver biopsies. Core-needle biopsies from patients with a diagnosis of ACLF (n = 152) as per the European Association for the Study of the Liver criteria were included during 8 years. Liver biopsies from 98 patients with compensated chronic liver disease were included as disease controls for histologic comparison. Features of ongoing changes, such as hepatic necrosis, hepatic apoptosis, cholestasis, hepatocyte degeneration, bile ductular proliferation, Mallory-Denk bodies, steatosis, and extent of liver fibrosis, were analyzed for predicting short-term mortality (28 days). A P value of <.05 was considered significant. In our cohort of ACLF patients, the following etiologies for acute decompensation were identified: alcohol, 47 of 152 (30.9%); sepsis, 24 of 152 (15.7%); hepatotropic viruses, 20 of 152 (13.1%); drug-induced liver injury, 11 of 152 (7.2%); autoimmune flare, 9 of 152 (5.9%); mixed etiologies, 5 of 152 (3.2%); and cryptogenic, 36 of 152 (23.6%). On histologic examination, hepatic necrosis (P < .001), dense lobular inflammation (P = .03), cholestasis (P < .001), ductular reaction (P = .001), hepatocyte degeneration (P < .001), and absence of advanced fibrosis stages (P < .001) were identified significantly more othen in ACLF patients than in disease controls on univariate analysis. On multivariate Cox regression analysis, the absence of advanced Ishak histologic activity index fibrosis stages (P = .02) and the presence of dense lobular inflammation (P = .04) were associated with increased 28-day mortality in ACLF patients. After adjusting the clinical causes of acute decompensation, only dense lobular inflammation was found as an independent predictor of short-term mortality (P = .04) in ACLF patients. Dense lobular necroinflammatory activity is a clinically independent histologic predictor of 28-day short-term mortality in patients with ACLF.

Impact of nutritional and inflammatory status in patients with critical limb-threatening ischemia

A pro-inflammatory state and a poor nutritional status have been associated with severity and prognosis of patients with peripheral arterial disease (PAD). The clinical applicability of the different pre-operative nutritional and inflammatory biomarkers in patients with critical limb-threatening ischemia (CLTI) was analyzed. A retrospective observational study was performed, that included all patients with CLTI revascularized from January 2016 to July 2019. The inflammatory state was calculated using neutrophil/lymphocyte (NLR), lymphocyte/monocyte (LMR) and platelet/lymphocyte ratios (PLR). For nutritional status, the Prognostic Nutritional Index (PNI) was calculated. Mortality and number of major amputations at 6 months and hospital length-of stay were studied. 310 patients were included. Higher levels of NLR and lower levels of PNI were associated with mortality (6.61±5.6 vs. 3.98±3.27, P=0.034; 40.33±7.89 vs. 45.73±7.48, P=0.05, respectively). Lower levels of PNI and LMR (42.57±7.82 vs. 45.44±7.65, P=0.036; 2.77±1.61 vs. 3.22±1.75, P=0.013, respectively) and higher levels of NLR (6.91±7.85 vs. 3.94±2.57, P=0.023) were associated with major amputations. The mean hospital length-of-stay was higher in patients with lower levels of PNI and LMR (P=0.000 and P=0.003) and higher levels of NLR and PLR (P=0.001 and P=0.002). A PNI<42.87 predicted short-term mortality with a 66.7% of sensitivity and a 66.8% of specificity (P=0.000). Our experience suggests that these inflammatory and nutritional biomarkers are independent predictors of short-term mortality and major amputations. In addition, our results suggest that PNI could be used to predict the short-term mortality with high sensitivity and specificity.

Association of early glycemic change with short-term mortality in lobar and non-lobar intracerebral hemorrhage

The association between early glycemic change and short-term mortality in non-diabetic patients with acute intracerebral hemorrhage (ICH) is unclear. We retrospectively investigated non-diabetic patients with lobar (n = 262) and non-lobar ICH (n = 370). Each patient had a random serum glucose test on hospital admission and a fasting serum glucose test within the following 48 h. Hyperglycemia was defined as serum glucose ≥ 7.8 mmol/l. Four patterns were determined: no hyperglycemia (reference category), persistent hyperglycemia, delayed hyperglycemia, and decreasing hyperglycemia. Associations with 30-day mortality were estimated using Cox models adjusted for major features of ICH severity. Persistent hyperglycemia was associated with 30-day mortality in both lobar (HR 3.00; 95% CI 1.28–7.02) and non-lobar ICH (HR 4.95; 95% CI 2.20–11.09). In lobar ICH, 30-day mortality was also associated with delayed (HR 4.10; 95% CI 1.77–9.49) and decreasing hyperglycemia (HR 2.01, 95% CI 1.09–3.70). These findings were confirmed in Cox models using glycemic change (fasting minus random serum glucose) as a continuous variable. Our study shows that, in non-diabetic patients with ICH, early persistent hyperglycemia is an independent predictor of short-term mortality regardless of hematoma location. Moreover, in non-diabetic patients with lobar ICH, both a positive and a negative glycemic change are associated with short-term mortality.

Pressure-dimension index: A novel "morphologic-functional" index of right ventricle that predicts short-term survival after left ventricular assist device implantation.

Right ventricular failure (RVF) after left ventricular assist device (LVAD) implantation is a major cause of postoperative morbidity and mortality. Despite the availability of multiple imaging parameters, none of these parameters had adequate predictive accuracy for post-LVAD RVF. To study whether right ventricular pressure-dimension index (PDI), which is a novel echocardiographic index that combines both morphologic and functional aspects of the right ventricle, is predictive of post-LVAD RVF and survival. 49 cases that underwent elective LVAD implantation were retrospectively analyzed using data from an institutional registry. PDI was calculated by dividing systolic pulmonary artery pressure to the square of the right ventricular minor diameter. Cases were categorized according to tertiles. Patients within the highest PDI tertile (PDI>3.62mmHg/cm2 ) had significantly higher short-term mortality (42.8%) and combined short-term mortality and severe RVF (50%) compared to other tertiles (P<.05 for both, log-rank p for survival to 15th day 0.014), but mortality was similar across tertiles in the long-term follow-up. PDI was an independent predictor of short-term mortality (HR:1.05-26.49, P=.031) and short-term composite of mortality and severe RVF (HR:1.37-38.87, P=.027). Increased PDI is a marker of an overburdened right ventricle. Heart failure patients with a high PDI are at risk for short-term mortality following LVAD implantation.

Long-Term Mortality Related to Acute Kidney Injury Following Intracerebral Hemorrhage: A 10-Year (2010–2019) Retrospective Study

ObjectivesAcute kidney injury (AKI) following intracerebral hemorrhage (ICH) is an intractable medical complication and an independent predictor of short-term mortality. However, the correlation between AKI and long-term mortality has not been fully investigated. The aim of the present study was to determine the relationship between AKI following ICH and long-term mortality in a 10-year (2010–2019) retrospective cohort. Materials and MethodsA total of 1449 ICH patients were screened and enrolled at the Department of Neurosurgery, Southwest Hospital, Third Military Medical University (Army Medical University) from January 2010 to December 2016. The endpoint for follow-up was May 31, 2019. The estimated all-cause mortality was determined using Cox proportional hazard regression models. ResultsAmong 1449 ICH patients, 136 (9.4%) suffered from AKI, and the duration of follow-up was a median of 5.1 years (IQR 3.2–7.2). The results indicated that the risk factors for AKI without preexisting chronic kidney disease (CKD) in the multivariable analysis were age (p = 0.002), nephrotoxic antibiotics (p = 0.000), diabetes mellitus (p = 0.005), sepsis (p = 0.000), antiplatelet therapy (p = 0.002), infratentorial hemorrhage (p = 0.000) and ICH volume (p = 0.003). Age (p = 0.008), ACEIs/ARBs (p = 0.010), nephrotoxic antibiotics (p = 0.014), coronary artery disease (p = 0.009), diabetes mellitus (p = 0.014), hypertension (p = 0.000) and anticoagulant therapy (p = 0.000) were independent predictors of AKI with preexisting CKD. Meanwhile, the data demonstrated that the estimated all-cause mortality was significantly higher in ICH patients with AKI without preexisting CKD (HR 4.208, 95% CI 2.946–6.011; p = 0.000) and in ICH patients with AKI with preexisting CKD (HR 2.470, 95% CI 1.747–3.492; p = 0.000) than in those without AKI. ConclusionsAKI is a long-term independent predictor of mortality in ICH patients. Thus, renal function needs to be routinely determined in ICH patients during clinical practice.
