Early mNGS testing for diagnose and prognostic prediction of early onset pneumonia among in-hospital cardiac arrest patients undergoing extracorporeal cardiopulmonary resuscitation

ObjectivesMetagenomic next-generation sequencing (mNGS) is emerging as a novel diagnostic technology for various infectious diseases; however, limited studies have investigated its application in etiological diagnosis of early onset pneumonia (EOP) among patients undergoing extracorporeal cardiopulmonary resuscitation (ECPR) following in-hospital cardiac arrest (IHCA), The clinical significance of early mNGS in predicting short-term prognosis of IHCA patients after ECPR remains unclear.MethodsThis retrospective study included 76 patients with IHCA who underwent ECPR at the First Affiliated Hospital of Zhengzhou University from January 2018 to December 2022. Baseline characteristics and etiological data of all patients during their hospitalization were collected and statistically analyzed. The primary outcome of this study was the diagnosis of EOP, while the secondary outcomes included successful extracorporeal membrane oxygenation (ECMO) weaning and survival at discharge. Additionally, the characteristics of bronchoalveolar lavage fluid (BALF) flora in these patients were compared by analyzing both mNGS results and culture results.ResultsMultivariate logistic regression were employed to analyze the predictors of ECMO weaning failure, mortality at discharge, and the incidence of EOP. Ultimately, patients with lower SOFA scores on admission [OR (95%CI): 1.447 (1.107-1.890), p=0.007] and those who underwent early mNGS testing within 48 hours after ECPR [OR (95%CI): 0.273 (0.086-0.865), p=0.027] demonstrated a higher probability of successful weaning from ECMO. Patients with higher SOFA scores on admission [OR (95%CI): 2.404 (1.422-4.064), p=0.001], and elevated lactate levels [OR (95%CI): 1.176 (1.017-1.361), p=0.029] exhibited an increased likelihood of mortality at discharge. Furthermore, early mNGS detection [OR (95%CI): 0.186 (0.035-0.979), p=0.047], and lower CRP levels (48h-7d after ECMO) [OR (95%CI):1.011 (1.003-1.019), p=0.006] were associated with a reduced incidence of EOP. In addition, the pathogens detected by mNGS within 48 hours after ECPR were mainly oral colonizing bacteria and viruses, and viruses were in the majority, while all BALF cultures were negative. In contrast, between 48 hours and 7 days after ECPR, BALF cultures were positive in all EOP patients.ConclusionsEarly mNGS testing to identify microbial flora facilitates timely adjustment of antibiotic regimens, thereby reducing the incidence of EOP and improving short-term prognosis in patients undergoing ECPR following IHCA.

Impact of Impella5.0/5.5 use on short-term prognosis in patients with AMI-related cardiogenic shock receiving Impella-incorporated MCS in Japan

Abstract Background The short-term prognosis in patients with acute myocardial infarction-related cardiogenic shock (AMI-CS) remains unsatisfactory even in the era of Impella. The survival benefit of Impella 5.0/5.5 use remains uncertain. Purpose This study examined the clinical impact of Impella device type on clinical outcomes among patients with AMI-CS receiving Impella support using the prospective multi-center J-PVAD registry data. Methods We included patients with AMI-CS who received Impella-incorporated temporary MCS and were enrolled in the J-PVAD registry between Feb 2022 and Dec 2023. The primary outcome was 30-day survival. Results A total of 2405 patients (average 71 y; LVEF 30%; Lac 5.6 mmol/L) were included. 1409 (58.6%) patients received Impella alone and the others (41.4%) received ECPELLA support. Patients who received ECPELLA had a lower 30-day survival compared to those receiving Impella alone (46.1% vs 62.3%, p < 0.0001). Of note, patients who received ECMO with Impella5.0/5.5 had a greater survival compared to those who received ECMO with Impella2.5/CP (64.4% vs 43.0%, Figure 1). Conclusions Patients who received ECPELLA had a lower 30-day survival compared to Impella alone. Impella 5.0/5.5 use may improve prognosis for those with ECMO support in AMI-CS.

Association of culprit lesions with in-hospital mortality in patients with acute coronary syndrome complicated by cardiogenic Shock

Abstract Background/Introduction The Society for Cardiovascular Angiography and Interventions (SCAI) shock stage is useful for stratifying short-term prognosis in patients with acute coronary syndrome (ACS). However, the impact of culprit lesion location for ACS on prognostic stratification by the SCAI shock stage remains insufficiently elucidated. Purpose This study aims to investigate the association between culprit lesion location for ACS and shock severity on in-hospital mortality. Methods We retrospectively investigated consecutive ACS patients who underwent percutaneous coronary intervention at a single center between January 2014 and October 2023. Patients were classified into five groups (No risk, Stage A, Stage B, Stage C, and Stage E) based on data at arrival in the emergency department using SCAI classification. The following culprit lesions were included in this analysis: left main coronary artery (LMCA), proximal right coronary artery (RCA), proximal left anterior descending artery (LAD), and proximal left circumflex artery (LCX). Results Of 1,665 patients included in the analysis, the mean age was 72±12 years, and females accounted for 26% overall. The distribution of SCAI shock stages by culprit lesions is shown in Figure 1. The proportion of stage B or higher in the LMCA, RCA, LAD, and LCX was 41%, 23%, 24%, and 24%, respectively. The corresponding in-hospital mortality was 20%, 3%, 5%, and 3%, respectively. The trend of in-hospital mortality stratified by shock severity and culprit lesions is demonstrated in Figure 2. LMCA and LAD showed increased in-hospital mortality with progressing shock severity. In contrast, this trend was not observed for RCA and LCX. Conclusions Except for LMCA, the proportion of shock stage B or higher was comparable. SCAI shock stage classification was useful in stratifying in-hospital mortality in patients where culprit lesions for ACS were LMCA and proximal LAD. Conversely, its validity in those with proximal RCA and LCX may be limited.

Levosimendan improves the early prognosis of patients with Non ST-segment elevation myocardial infarction and Killip class > II

Abstract Background Levosimendan is an inotropic agent known for its calcium-sensitizing myofilament effect and ATP-dependent potassium channel opening mechanism, which enhances myocardial contractility without increasing oxygen consumption. Despite its potential benefits, the impact of levosimendan on the prognosis of patients with myocardial infarction remains uncertain and requires further investigation through larger-scale studies. Purpose This study aimed to investigate the effect of levosimendan on the short-term prognosis of patients with Non-ST-segment elevation myocardial infarction (NSTEMI) and Killip> II. Methods The data for this study were derived from the Health and Medical Big Data Superplatform, comprising a retrospective cohort of patients admitted to and discharged from 72 secondary and tertiary hospitals in the City from 2010 to 2023. A total of 12472 patients with NSTEMI and Killip > II were included. Patients were divided into the levosimendan group and the non-leosimendan group based on whether levosimendan was used during hospitalization. Propensity score matching (PSM) was employed to balance covariates between the two groups. Multivariate Cox regression was used to evaluate the relationship between levosimendan and clinical outcomes. Covariates adjusted in PSM included age, sex, Killip class, early PCI, previous PCI, previous medical conditions (diabetes, hypertension, ischemic stroke, and chronic kidney disease), and medications during hospitalization (aspirin, clopidogrel, indobufen, ticagrelor, statins, cedilanid, recombinant human brain natriuretic peptide [rhBNP], milrinone, dopamine, dobutamine, and angiotensin converting enzyme inhibitor/angiotensin receptor blockers [ACEI/ARB]). The primary endpoint was major cardiovascular and cerebrovascular adverse events (MACCE), defined as the composite endpoint of cardiac death, myocardial infarction, and ischemic stroke within 3 months. Results The levosimendan group comprised 782 patients, while the non-leosimendan group included 11690 patients. After PSM, the covariates were balanced, resulting in 756 well-matched pairs. In PSM patients, the levosimendan group exhibited a significantly lower incidence of MACCE (aHR, 0.573; 95%CI, 0.466–0.704; p < 0.001) and cardiac death (aHR, 0.500; 95%CI, 0.399-0.626; p < 0.001). However, there was no significant difference in the incidence of myocardial infarction and ischemic stroke. Conclusions Levosimendan was associated with a lower incidence of MACCE within 3 months in patients with NSTEMI and Killip> II, mainly driven by lower incidence of cardiac death. However, these findings are based on observational data and require confirmation through adequately powered, randomized, controlled trials.

The Impact of Blood Pressure Rhythm and Perioperative Blood Pressure Variability on Short-Term Prognosis in Patients with Type A Aortic Dissection.

Aims/Background Previous studies have indicated a strong correlation between disturbances in blood pressure (BP) circadian rhythm and major cardiovascular adverse events. Similarly, blood pressure variability (BPV) has been closely linked to cerebral small vessel disease and leukoaraiosis. This study aims to investigate the relationship between BP rhythm and BPV with the short-term prognosis of patients with Type A aortic dissection, offering insights for targeted perioperative nursing interventions and improving patient outcomes. Methods This retrospective study included patients undergoing surgical treatment for Type A aortic dissection at Guangdong Provincial People's Hospital (Guangdong Academy of Medical Sciences) from June 2022 to March 2024. The study followed patients from the completion of surgery to 30 days postoperatively, with all-cause mortality within 30 days as the endpoint representing poor short-term prognosis. Clinical data were compared along with: types of BP rhythm; BPV parameters including the mean 24-hour systolic BP (24hSBP), 24-hour diastolic BP (24hDBP), and pulse pressure; and the coefficient of variability (CV) for 24hSBP, 24hDBP, and pulse pressure. Multivariate logistic regression analysis was utilized to identify risk factors for poor short-term outcomes in these patients, and receiver operating characteristic (ROC) curves were plotted to assess the predictive value of BP rhythm types and BPV indicators. Results The study ultimately included 115 participants, with 31 deaths occurring within 30 days post-surgery, resulting in a postoperative mortality rate of 26.96%. The multivariate logistic regression analysis revealed that white blood cell count, neutrophil count, non-dipping BP rhythm, pulse pressure, and the CV for 24hSBP, 24hDBP, and pulse pressure, were significant risk factors for poor short-term prognosis (p < 0.05). The ROC curve analysis demonstrated that non-dipping BP rhythm, pulse pressure, 24hSBP-CV, 24hDBP-CV, and pulse pressure-CV had areas under the curve (AUC) of 0.685, 0.749, 0.751, 0.773, and 0.763, respectively. The combination of these indicators yielded the highest AUC at 0.918. Conclusion A combination of BP rhythm and BPV indicators provides significant predictive value for poor short-term outcomes in patients with Type A aortic dissection. Clinicians and nursing staff can use these features to formulate targeted preventive measures.

Aspartate aminotransferase to alanine aminotransferase ratio and short-term prognosis of patients with type 2 diabetes hospitalized for heart failure

IntroductionWe aimed to explore the prognostic value of the aspartate aminotransferase to alanine aminotransferase (AST/ALT) ratio in non-surgical patients with type 2 diabetes hospitalized for heart failure.Material and methodsUsing a large electronic medical record-based cohort of diabetes in China (WECODe), we gathered data on non-surgical hospitalized patients with type 2 diabetes and heart failure from 2011 to 2019. Baseline AST/ALT ratio was calculated. The primary outcomes were all-cause death within 30 days after discharge, composite cardiac events, major acute kidney injury, and major systemic infection. A multivariable Cox proportional regression model was utilized to evaluate the association between the AST/ALT ratio and outcomes.ResultsThis retrospective cohort included 8,073 patients (39.4% women) with type 2 diabetes hospitalized for heart failure. The median age was 71 years. Higher AST/ALT ratio was associated with higher risks of poor endpoints (with per standard deviation increment in AST/ALT ratio, for death within 30 days after discharge: adjusted hazard ratio [HR], 1.35, 95% confidence interval [CI], 1.21 to 1.50; for composite cardiac events: HR, 1.18, 95% CI: 1.06 to 1.31). Compared to patients in the lowest quartile for the AST/ALT ratio, those in the highest quartile have elevated risk of death within 30 days after discharge and major systemic infection (HRs [95% CIs]: 1.61 [1.18 to 2.19] and 1.28 [1.06 to 1.56], respectively). Subgroup analyses and sensitivity analyses confirmed the robustness of the findings.ConclusionsType 2 diabetes patients hospitalized for heart failure with the AST/ALT ratio in the highest quartile face a poor short-term prognosis.

A retrospective study on the relationship between plasma β-hydroxybutyric acid levels and short-term prognosis of cardiac function in patients with acute myocardial infarction combined with heart failure

Abstract Background Ketone body metabolism can improve cardiomyocytes metabolism and reduce myocardial oxygen consumption; however, its role in the short-term prognosis of patients with acute myocardial infarction combined with heart failure has not been clearly elucidated. The aim of this study was to investigate the effect of β-hydroxybutyric acid, the main component of ketone bodies, on the short-term prognosis of patients with acute myocardial infarction combined with heart failure. Methods This was a retrospective observational study that enrolled patients admitted to the Qilu Hospital of Shandong University for acute myocardial infarction combined with heart failure between January 1, 2019, and December 31, 2022. According to whether β-hydroxybutyric acid was elevated or not, subjects were divided into a β-hydroxybutyric acid elevated and nonelevated groups, to observe the difference in cardiac function improvement between the two groups. Results This study included a total of 260 patients, of which 170 exhibited elevated levels of β-hydroxybutyric acid. Compared to the patients in the nonelevated group, patients in the elevated β-hydroxybutyric acid group had higher plasma levels of creatine kinase myocardial band and greater Gensini scores. Multivariate logistic regression analysis indicated that an increase in β-hydroxybutyric acid levels (odds ratio: 2.517; 95% confidence intervals: 1.394–4.597; P = 0.002) is an independent protective factor affecting the prognosis of cardiac function in patients with acute myocardial infarction combined with heart failure. Conclusion In patients with acute myocardial infarction combined with heart failure, plasma β-hydroxybutyric acid serves as an independent protective factor for short-term improvement in cardiac function.

Dynamic change of lymphocytes associated with short-term prognosis in anti-MDA5-positive dermatomyositis with interstitial lung disease: a multicenter retrospective study

Lymphopenia is a unique manifestation of anti-MDA5 positive dermatomyositis with interstitial lung disease (MDA5 + DM-ILD). This study aimed to investigate the relationship between dynamic changes in peripheral lymphocytes and short-term prognosis in patients of MDA5 + DM-ILD. Two hundred sixty-three MDA5 + DM-ILD patients were divided into different groups according to lymphocyte count and death or survival within 1 month, then the differences in clinical features and outcomes were compared. Associations between lymphocytes and risk of death within 1 month were also investigated in different lymphocyte groups using Cox proportional hazard models. A generalized additive mixed model (GAMM) was established to analyze the dynamic changes of lymphocytes in the death 1-month group. Lymphocytes of the patients who died within 1 month were significantly lower than survivors by different lymphocyte grouping methods, and the total lymphocytes showed a gradually decreasing trend in non-survivors. And the difference between survivors and non-survivors was more obvious over time. The lowest tertile of baseline lymphocytes as a reference, the hazard ratios for death within 1 month in the highest tertile were 0.497 (95% CI 0.26–0.949, P for trend = 0.033) after adjustment for potential confounders. GAMM analysis found a mean daily decrease of lymphocytes (0.034 × 10^9/L) after admission in death 1-month patients. Low baseline lymphocytes and gradually declined lymphocytes are both associated with a high risk of death within 1 month. However dynamic changes in lymphocytes can better reflect the disease status and better predict the short-term prognosis than baseline lymphocytes in MDA5 + DM-ILD patients.Key points•Low baseline lymphocytes and gradually decreased trend along time correlated with poor short-term prognosis in MDA5 + DM-ILD patients.•Dynamic changes of lymphocytes can better reflect the disease status and better predict the 1-month prognosis than baseline lymphocytes in MDA5 + DM-ILD patients.•Generalized additive mixed model (GAMM) analysis found that in 1-month non-survivors, peripheral blood lymphocytes decreased by 0.034 × 10^9/L per day, while the lymphocytes in survivors gradually increased.

Prediction model for poor short-term prognosis in patients with chronic subdural hematoma after burr hole drainage: a retrospective cohort study.

Chronic subdural hematoma (CSDH) is a common condition in neurosurgery. With an aging population, there is increasing attention on the prognosis of patients following surgical intervention. We developed a postoperative short-term prognostic prediction model using preoperative clinical indicators, aiming to assist in perioperative medical decision-making and management. The dataset was randomly divided into training and validation cohorts. An mRS score greater than 2 one month after discharge was considered indicative of a poor prognosis. In the training cohort, the least absolute shrinkage and selection operator (LASSO) regression analysis was used for multivariate analysis to identify independent risk factors and construct a prediction nomogram for poor prognosis one month after discharge. The performance of the nomogram was assessed using the Receiver Operating Characteristic (ROC) curve and calibration curve. A Decision Curve Analysis (DCA) was also conducted to determine the net benefit threshold of the prediction model. Among the 505 participants, 18.8% (95/505) had a poor prognosis one month after discharge. The baseline characteristics did not significantly differ between the training cohort and the validation cohort. LASSO regression analysis in the training cohort reduced the predictors to four potential factors. Further multivariate logistic analyses in the training cohort identified four independent predictors: age, admission Glasgow Coma Scale (GCS) score, hemiparesis, and hemoglobin count. These predictors were incorporated into the nomogram prediction model. Internal validation using ROC analysis, calibration curves, and other methods demonstrated a strong correlation between the observed and predicted likelihood of poor prognosis one month after discharge. The visualized nomogram prediction model we developed for short-term postoperative prognosis of chronic subdural hematoma after burr hole drainage aids in predicting short-term outcomes and guiding clinical treatment decisions. Further external validation is needed in the future to confirm its effectiveness.

Impact of the spleen size on short-term prognosis in patients with cardiogenic shock receiving Impella-incorporated temporary mechanical circulatory support.

The spleen size may be associated with mortality and morbidity in patients with heart failure, whereas its clinical implication in patients with cardiogenic shock receiving Impella-incorporated temporary mechanical circulatory support (MCS) remains unknown. Patients who received Impella-incorporated temporary MCS in our institute between March 2018 and August 2023 were eligible. The splenic volume index (SVI) was retrospectively calculated in all participants by measuring spleen size on the computed tomography obtained at the time of Impella placement. The impact of baseline SVI/central venous pressure (CVP) ratio on the 30-day mortality after Impella placement was evaluated. A total of 74 patients (70years old, 62% men) were included. Median baseline SVI was 71.6 (50.3, 92.1) mL/m2. A lower SVI was associated with more decreased cardiac output and a higher SVI was associated with more elevated CVP (p < 0.05 for both). A lower SVI/CVP ratio was associated with higher 30-day mortality with an adjusted hazard ratio of 3.734 (95% confidence interval 1.397-9.981, p = 0.009). A baseline lower SVI/CVP ratio was associated with short-term mortality in patients receiving Impella-incorporated temporary MCS.

Interpretable Machine Learning Model for Predicting the Prognosis of Guillain-Barré Syndrome Patients.

Machine learning (ML) is increasingly used in medical predictive modeling, but there are no studies applying ML to predict prognosis in Guillain-Barré syndrome (GBS). The medical records of 223 patients with GBS were analyzed to construct predictive models that affect patient prognosis. Least Absolute Shrinkage and Selection Operator (LASSO) was used to filter the variables. Decision Trees (DT), Random Forest (RF), Extreme Gradient Boosting (XGBoost), k-nearest Neighbour (KNN), Naive Bayes (NB), Neural Network (NN). Light Gradient Boosting Machine (LGBM) and Logistic Regression (LR) were used to construct predictive models. Clinical data from 55 GBS patients were used to validate the model. SHapley additive explanation (SHAP) analysis was used to explain the model. Single sample gene set enrichment analysis (ssGSEA) was used for immune cell infiltration analysis. The AUCs (area under the curves) of the 8 ML algorithms including DT, RF, XGBoost, KNN, NB, NN, LGBM and LR were as follows: 0.75, 0.896 0.874, 0.666, 0.742, 0.765, 0.869 and 0.744. The accuracy of XGBoost (0.852) was the highest, followed by LGBM (0.803) and RF (0.758), with F1 index of 0.832, 0.794, and 0.667, respectively. The results of the validation set data analysis showed AUCs of 0.839, 0.919, and 0.733 for RF, XGBoost, and LGBM, respectively. SHAP analysis showed that the SHAP values of blood neutrophil/lymphocyte ratio (NLR), age, mechanical ventilation, hyporeflexia and abnormal glossopharyngeal vagus nerve were 0.821, 0.645, 0.517, 0.401 and 0.109, respectively. The combination of NLR, age, mechanical ventilation, hyporeflexia and abnormal glossopharyngeal vagus used to predict short-term prognosis in patients with GBS has a good predictive value.

Development of a short-term prognostic model for anti-N-methyl-D-aspartate receptor encephalitis in Chinese patients

BackgroundRecognizing the predictors of poor short-term prognosis after first-line immunotherapy in patients with anti-N-methyl-D-aspartate receptor (anti-NMDAR) encephalitis is essential for individualized treatment strategy. The objective of this study was to ascertain the factors that forecast short-term prognosis in patients with anti-NMDAR encephalitis, develop a prognostic prediction model, and authenticate its efficacy in an external validation cohort. Further, all patients were followed-up long-term to assess the factors of long-term outcome and relapses.MethodsA prospective enrollment of patients diagnosed with anti-NMDAR encephalitis was conducted across five clinical centers in China from June 2014 to Mar 2022. The enrolled patients were divided into the derivation and validation sets based on enrollment time. The short-term prognostic model was visualized using a nomogram. Further, all patients were followed-up long-term to assess the factors of long-term outcome.ResultsThis study found that poor short-term prognosis was a risk factor for poor long-term outcome (6-month prognosis, OR 29.792, 95%CI 6.507-136.398, p < 0.001; 12-month prognosis, OR 15.756, 95%CI 3.384–73.075, p < 0.001; 24-month prognosis, OR 5.500, 95%CI 1.045–28.955, p = 0.044). Abnormal behavior or cognitive dysfunction (OR 8.57, 95%CI 1.48–49.79, p = 0.017), consciousness impairment (OR19.32, 95%CI 3.03-123.09, p = 0.002), autonomic dysfunction or central hypoventilation (OR 5.66, 95%CI 1.25–25.75, p = 0.025), CSF pleocytosis (OR 4.33, 95%CI 1.48–12.65, p = 0.007), abnormal EEG (OR 5.48, 95% CI 1.09–27.54, p = 0.039) were independent predictors for a poor short-term prognosis after first-line immunotherapy. A nomogram that incorporated those factors showed good discrimination and calibration abilities. The area under the curve (AUC) for the prognostic model were 0.866 (95%CI: 0.798–0.934) with a sensitivity of 0.761 and specificity of 0.869.ConclusionWe established and validated a prognostic model that can provide individual prediction of short-term prognosis after first-line immunotherapy for patients with anti-NMDAR encephalitis. This practical prognostic model may help neurologists to predict the short-term prognosis early and potentially assist in adjusting appropriate treatment timely.

Importance of fourth heart sound and preserved left atrial function in wild-type transthyretin amyloidosis.

A fourth heart sound (S4) was reported to be almost never present in patients with amyloid light-chain cardiomyopathy. There have been no reports on S4 in patients with wild-type transthyretin amyloid cardiomyopathy (ATTRwt-CM). This study aimed to clarify the clinical implications of S4 in patients with ATTRwt-CM. Seventy-six patients with ATTRwt-CM (mean age: 80.4±5.4years, 68 males) who had undergone phonocardiography (PCG) were retrospectively assessed. We measured S4 amplitude on digitally recorded PCG. S4 was considered to be present when its amplitude was 1.0mm or greater on the PCG. Distinct S4 was defined as S4 with an amplitude of 2.0mm or greater, which is usually recognizable by auscultation. According to the rhythm and presence or absence of S4, the patients were divided into three groups, namely, sinus rhythm (SR) with S4, SR without S4, and non-SR. Non-SR consisted of atrial fibrillation, atrial flutter, and atrial tachycardia. Thirty-six patients were in SR and the remaining 40 patients were in non-SR. In the 36 patients in SR, S4 was shown by PCG to be present in 17 patients (47%), and distinct S4 was recognized in 7 patients (19%) by auscultation. In patients who were in SR, those with S4 had higher systolic blood pressure (124±15 vs. 99±8mmHg, P<0.001), lower level of plasma B-type natriuretic peptide (308 [interquartile range (IQR): 165, 354] vs. 508 [389, 765] pg/mL, P=0.034) and lower level of high-sensitivity cardiac troponin T (0.068 [0.046, 0.089] vs. 0.109 [0.063, 0.148] ng/mL, P=0.042) than those without S4. There was no significant difference in left atrium (LA) volume index or LA reservoir strain between patients with S4 and without S4. Patients with S4 had more preserved LA systolic function than those without S4 (peak atrial filling velocity: 53±25 vs. 34±9cm/s, P=0.033; LA contractile strain: 4.1±2.1 vs. 1.6±2.0%, P=0.012). Patients in SR without S4 had worse short-term prognosis compared with the other two groups (generalized Wilcoxon test, P=0.033). S4 was present in 47% of the patients in SR with ATTRwt-CM. Patients in SR without S4 had more impaired LA systolic function than those in SR with S4. The absence of S4 portends a poor short-term prognosis in patients with ATTRwt-CM.

The Value of Serum Procalcitonin, Thromboelastography Combined with Platelet Count in Predicting the Short-Term Progression of Septic Shock in the Intensive Care Unit.

By evaluating the level of serum procalcitonin (PCT), thromboelastography (TEG) and platelet count (PLT) of patients with septic shock in intensive care unit (ICU), the predictive value of the combination of the three indicators on the short-term progression was discussed, which provided a new basis for early clinical diagnosis and disease evaluation. The clinical data of 130 patients with septic shock admitted to the IUC of our hospital from December 2021 to December 2023 were analyzed retrospectively. These subjects were divided into good prognosis group (n=78) and poor prognosis group (n=52) according to the 28 d deaths. The influencing factors were explored using the Multivariate logistic regression analysis. The value of single or combined PCT, PLT and TEG in predicting poor short-term prognosis was assessed using the receiver operating characteristic (ROC) curve. The patients in poor prognosis group had higher Acute Physiology and Chronic Health Evaluation II (APACHE II) scores, serum PCT level, coagulation reaction time (R value) and coagulation formation time (K value), but lower PLT levels, final strength of coagulation (MA value) and coagulation formation rate (α angle) than those in good prognosis group (P<0.001). PCT, R value and K value were risk factors (P<0.001), while PLT, MA value and α angle were protective factors (P<0.001). The area under the curve (AUC) of PCT, PLT and TEG predicting poor short-term progression was 0.813, 0.658 and 0.752, respectively. The AUC of combined three indicators was 0.905, which had the highest predictive value. Serum levels of PCT, PLT and TEG had certain value in predicting poor short-term progression of septic shock patients, and their combined diagnostic value was higher. Therefore, regular monitoring of these three indicators could provide certain guiding significance for the prevention and treatment of poor short-term prognosis in patients with septic shock.

Association of bioimpedance analysis parameters trajectories with clinical outcomes in neurocritical patients

Background and objectiveNeurocritical patients often experience uncontrolled high catabolic metabolism state during the acuta phase of the disease. The complex interactions of neuroendocrine, inflammation, and immune system lead to massive protein breakdown and changes in body composition. Bioelectrical impedance analysis (BIA) evaluates the content and proportions of body components based on the principles of bioelectricity. Its parameters reflect the overall health status of the body and the integrity of cellular structure and function, playing an important role in assessing the disease status and predicting prognosis of such patients. This study explored the association of BIA parameters trajectories with clinical outcomes in neurocritical patients. MethodsThis study prospectively collected BIA parameters of 127 neurocritical patients in the Department of Neurology admitted to the NICU for the first 1–7 days. All these patients were adults (≥18 years old) experiencing their first onset of illness and were in the acute phase of the disease. The group-based trajectory modeling (GBTM), which aims to identify individuals following similar developmental trajectories, was used to identify potential subgroups of individuals based on BIA parameters. The short-term prognosis of patients in each trajectory group with variations in phase angle (PA) and extracellular water/total body water (ECW/TBW) over time was differentially analyzed, and the logistic regression model was used to analyze the relationship between potential trajectory groups of PA and ECW/TBW and the short-term prognosis of neurocritical patients. The outcome was Glasgow Outcome Scale (GOS) score at discharge. ResultsFour PA trajectories and four ECW/TBW trajectories were detected respectively in neurocritical patients. Among them, compared with the other latent subgroups, the “Low PA rapidly decreasing subgroup” and the “High ECW/TBW slowly rising subgroup” had higher incidences of adverse outcomes at discharge (GOS:1–3), in-hospital mortality, and length of neurology intensive care unit stay (all P < 0.05). After correcting for potential confounders, compared with the “Low PA rapidly decreasing subgroup”, the risk of adverse outcome (GOS:1–3) was lower in the other three PA trajectories, with OR values of 0.0003, 0.0004, and 0.003 respectively (all P < 0.05). Compared with the “High ECW/TBW slowly rising subgroup”, the risk of adverse outcome (GOS:1–3) was lower in the other three ECW/TBW trajectories, with OR values of 0.013, 0.035 and 0.038 respectively (all P < 0.05). ConclusionLatent PA trajectories and latent ECW/TBW trajectories during 1–7 days after admission were associated with the clinical outcomes of neurocritical patients. The risk of adverse outcomes was highest in the “Low PA rapidly decreasing subgroup” and the “High ECW/TBW slowly rising subgroup”. These results reflected the overall health status and nutritional condition of neurocritical patients at the onset of the disease, and demonstrated the dynamic change process in body composition caused by the inflammatory response during the acute phase of the disease. This provided a reference basis for the observation and prognostic evaluation of such patients.

Analysis of the Effects of Preoperative Hepatic Artery Chemoembolization and Quality Nursing Intervention on the Perioperative Safety and Short-term Prognosis of Liver Transplantation in Patients with Hepatocellular Carcinoma

Objective: To investigate the effects of preoperative hepatic artery chemoembolization (TACE) and quality nursing interventions on the perioperative safety and short-term prognosis in patients with hepatocellular carcinoma undergoing liver transplantation. Methods: The study period spanned from January 2021 to December 2023, and 125 patients with hepatocellular carcinoma admitted to our hospital were selected, all of whom underwent liver transplantation. They were randomly divided into an observation group (n = 63) and a control group (n = 62). The patients in the control group did not undergo TACE before the operation, and the patients in the observation group underwent TACE and quality nursing intervention before the operation. The operation time, intraoperative blood loss, length of hospitalization, liver-free period, complication rate, short-term prognosis, and liver function indexes between the two groups were compared. Results: There was no significant difference in operation time, intraoperative blood loss, and length of hospitalization between the two groups (P &lt; 0.05). The liver-free period of patients in the observation group was longer than that of the control group (P &lt; 0.05). The two groups had no significant difference in the incidence of biliary complications, vascular complications, and postoperative infections (P &gt; 0.05). The rate of immune reactive complications in the observation group was lower than that of the control group (P &lt; 0.05). There was no significant difference in the perioperative mortality rate, 1-year postoperative survival rate, and 2-year postoperative survival rate (P &gt; 0.05). The two groups had no significant difference in postoperative liver function indexes (P &gt; 0.05). Conclusion: Preoperative TACE and high-quality nursing intervention in patients with hepatocellular carcinoma had no adverse effect on the perioperative safety and short-term prognosis, prolonged the liver-free time, and reduced the incidence of immune-reactive complications.

Urinary catheterization of patients with acute heart failure in a hospital emergency department: a factor associated with prognosis.

To analyze whether urinary catheterization in a hospital emergency department (ED) affects short-term prognosis in patients with acute heart failure (AHF). We prospectively recorded baseline and other clinical data in a consecutive cohort of ED patients treated for AHF. Crude and adjusted associations were calculated between catheterization and a primary composite outcome (30-day readmission for AHF and/or death) and secondary outcomes (in-hospital mortality, urinary tract infection [UTI], and duration of hospital stay.). Nine hundred ninety-one patients were admitted for AHF. The mean (SD) age was 66 (10.5) years; 71% were women. Catheterization was required for 29.2% in the ED. The primary composite outcome was observed in 7.7% of the patients who were not catheterized and 12.8% of the catheterized patients (P = .02). In-hospital mortality occurred in 5.9% and 9.7% of non-catheterized and catheterized patients, respectively (P = .04), and UTIs occurred in 19.1% and 26.6% (P = .01). Twelve of the non-catheterized patients (1.7%) were readmitted for AHF (vs 11 (3.8%) of the catheterized patients (P = .06), and there were no differences between the groups in hospital stay (11 vs 10.9 days, P = .78). In the adjusted analysis of associations between catheterization and the primary outcome the odds and hazard ratios (OR and HR, respectively) were OR, 1.7 (95% CI, 1.1-2.7) (P = .02) and HR, 1.6 (95% CI, 1.1-2.5) (P = .03). For secondary outcomes, significant associations emerged between catheterization and UTIs (OR, 1.8 [95% CI, 1.1-2.2]; P = .008) and readmission for AHF (OR, 2.9 [95% CI, 1.2-7.3]; P = .02). Routine insertion of a urinary catheter in patients with AHF in the ED is associated with worse 30-day clinical outcomes.

Lower Melatonin Indicates Poor Short-term Prognosis in Patients with Acute Ischemic Stroke.

We evaluated endogenous melatonin levels in the acute phase of cerebral infarction and explored the impact of possible changes in melatonin levels on the prognosis of patients. This study recruited acute ischemic stroke (AIS) patients from the Department of the Second Affiliated Hospital of Soochow University between December 2019 and June 2021, along with healthy control subjects. Salivary melatonin samples were collected from each participant between 7 pm and 10 pm, and fasting plasma was collected the following morning to measure the levels of inflammatory markers. The prognosis was assessed through follow-up three months after discharge. The relationship between melatonin levels and plasma inflammatory markers was assessed, followed by an analysis of the effect of melatonin levels on patient prognosis. The study enrolled a total of 160 participants, including 120 AIS patients aged 50 years or older (61.7% male) and 40 age-matched controls (55.0% male). The AIS group exhibited lower salivary melatonin levels at 19 (P = 0.002), 20 (P < 0.001), 21 (P < 0.001), and 22 (P < 0.001) o'clock, and the average melatonin level was also lower (P < 0.001). Logistic regression analysis models indicated an association between low melatonin levels and poor prognosis. Salivary melatonin levels demonstrated good predictive ability for the prognosis of AIS patients. Melatonin levels were lower in AIS patients compared to controls. In addition, lower melatonin levels were associated with a poorer prognosis among AIS patients.

The impact of skeletal muscle index at the third lumbar spine on nosocomial deterioration and short-term prognosis in acute pancreatitis: a retrospective observational study.

To investigate the impact of the third lumbar skeletal muscle index (L3-SMI) assessed by CT on the in-hospital severity and short-term prognosis of acute pancreatitis. A total of 224 patients with severe acute pancreatitis admitted to Yantaishan Hospital from January 2021 to June 2022 were selected as the subjects. Based on the in-hospital treatment outcomes, they were divided into a mortality group of 59 cases as well as a survival group of 165 cases. Upon admission, general information such as the Acute Physiology and Chronic Health Evaluation II (APACHE II) score, along with the abdominal CT images of each patient, were analyzed. The L3-SMI was calculated, and the Modified CT Severity Index (MCTSI) and Balthazar CT grade were used to assess the severity of in-hospital complications of acute pancreatitis. The evaluation value of L3-SMI for the prognosis of severe acute pancreatitis was analyzed, as well as the factors influencing the prognosis of severe acute pancreatitis. No statistically significant differences in gender, age, BMI, etiology, duration of anti-inflammatory drug use, and proportion of surgical patients between the survival and mortality groups were observed. But the mortality group showed higher proportions of patients with an elevated APACHE II score upon admission, mechanical ventilation, and renal replacement therapy, compared to the survival group, with statistically significant differences (P < 0.001). Furthermore, the mortality group had higher MCTSI scores (6.42 ± 0.69) and Balthazar CT grades (3.78 ± 0.45) than the survival group, with statistically significant differences (P < 0.001). The mortality group also had a lower L3-SMI (39.68 ± 3.25) compared to the survival group (42.71 ± 4.28), with statistically significant differences (P < 0.001). L3-SMI exhibited a negative correlation with MCTSI scores and Balthazar CT grades (r = -0.889, -0.790, P < 0.001). Logistic regression analysis, with mortality of acute pancreatitis patients as the dependent variable and MCTSI scores, Balthazar CT grades, L3-SMI, APACHE II score upon admission, mechanical ventilation, and renal replacement therapy as independent variables, revealed that MCTSI scores and L3-SMI were risk factors for mortality in acute pancreatitis patients (P < 0.001). Logistic regression analysis using the same variables confirmed that all these factors were risk factors for mortality in acute pancreatitis patients. This study confirmed that diagnosing muscle depletion using L3-SMI is a valuable radiological parameter for predicting in-hospital severity and short-term prognosis in patients with acute pancreatitis.
