ABSTRACT

Objective:To investigate the predictive value of neutrophil/lymphocyte ratio (NLR) on the discharge outcome in elderly patients with acute ischemic stroke (AIS) receiving intravenous thrombolysis (IVT).Methods:Elderly patients with AIS received IVT in the Department of Neurology, the Second Affiliated Hospital of Soochow University from August 2018 to August 2020 were retrospectively included. The modified Rankin Scale was used to evaluate discharge outcome, and the score >2 was defined as poor outcome. Symptomatic intracranial hemorrhage (sICH) was defined as any intracranial hemorrhage found on imaging examination accompanied by neurological deterioration, where the National Institutes of Health Stroke Scale (NIHSS) score increased by ≥4 from baseline or bleeding led to death. Multivariate logistic regression analysis was used to determine independent risk factors for sICH and poor discharge outcome. Receiver operating characteristic (ROC) curves were used to analyze the predictive value of NLR for sICH and poor discharge outcome. Results:A total of 228 elderly patients with AIS receiving IVT were enrolled, including 118 males (51.8%), aged 73.64±8.16 years, with a baseline NIHSS score of 6.23±6.54. Ninety patients (39.5%) had poor outcome at discharge, and 16 (7.0%) developed sICH. Univariate analysis showed that the NLR in the poor outcome group was significantly higher than that in the good outcome group ( P<0.01). Multivariate logistic regression analysis showed that a higher NLR was an independent risk factor for poor discharge outcome (odds ratio [ OR] 1.245, 95% confidence interval [ CI] 1.044-1.484; P< 0.05) and sICH ( OR 1.124, 95% CI 1.010-1.251; P<0.05). ROC curve analysis showed that the area under the curve of NLR for predicting poor discharge outcome was 0.693 (95% CI 0.620-0.765; P<0.01). The optimal cutoff value was 4.345. Its corresponding sensitivity and specificity were 47.8% and 87.7%, respectively. The area under the curve of NLR for predicting sICH was 0.651 (95% CI 0.498-0.804; P<0.05). The optimal cutoff value was 3.515. Its corresponding sensitivity and specificity were 68.8% and 61.8%, respectively. Conclusions:A higher NLR is independently associated with sICH and poor discharge outcome in elderly patients with AIS receiving IVT, and have certain predictive value for sICH and poor discharge outcome.

ABSTRACT

Objective:To explore the current situation of nursing human caring in hospital wards and analyze its influencing factors, so as to facilitate the development of nursing human caring practice.Methods:From July to November 2022, a total of 107 hospitals were surveyed through stratified convenience sampling method, and 4 072 ward nursing managers were recruited to finish the general information questionnaire and the ward nursing human caring status questionnaire. The general information included the region, class and type of the hospital, etc. The ward nursing human caring status questionnaire included 38 items in 5 dimensions of nursing human caring system and process, humanistic quality and training of nursing staff, humanistic environment and facilities, human caring procedures and measures, and human caring quality evaluation and improvement, with a full score of 190 points. Descriptive statistics were used to analyze the general data, independent samples t-test, ANOVA and correlation analysis were used to analyze the factors influencing the current status of nursing human caring in the ward, while multiple linear regression analysis was used to conduct a multivariate analysis. Results:The score of nursing human caring in hospital wards was 156.91±27.78. Whether the hospital had carried out nursing human caring pilot(demonstration) wards, whether the ward had previously been a hospital nursing human caring pilot(demonstration) nursing unit, the type of ward, and whether nursing managers had participated in human caring training were the influencing factors of the implication of nursing humanistic caring in wards( P<0.05). Conclusions:The practice of nursing human caring in hospital wards is at a good level, but needs to be further strengthened. Nursing managers should take systematically strategies to promote the development of nursing human caring practice.

ABSTRACT

Objective:To analyze the effect of inhibiting excessive mitochondrial fission mediated by dynamic related protein 1 (Drp1) on the function of injured cells and mitochondria in the septic myocardium, and to explore the protective effect of maintaining mitochondrial dynamic balance in the pathogenesis of sepsis induced cardiomyopathy(SIC).Methods:Rat H9C2 cardiomyocytes were cultured and stimulated with lipopolysaccharide (LPS) to establish a model of SIC. Mitochondrial division inhibitor 1 (Mdivi-1) was given 30 min before LPS stimulation. They were divided into the control group, LPS stimulated group (LPS), Mdivi-1 control group (Mdivi-1), and LPS+Mdivi-1 intervention group (LPS+Mdivi-1). CCK-8 was used to detect the cell viability, and lactate dehydrogenase (LDH) was used to detect cellular damage. A MitoTracker probe was used to observe mitochondrial morphology by laser scanning confocal microscopy, JC-1 staining was used to detect mitochondrial membrane potential level, a DCFH-DA probe was used to detect total ROS level, and an AnnexinV-FITC/PI probe was used to detect the cell apoptosis ratio. The expression levels of mitochondrial fission protein Drp1 and fusion proteins Optic Atrophy 1(Opa1) and Mitofusin2 (Mfn2) were detected by real-time PCR and Western blot. One-way ANOVA was used to compare the differences between groups, and the LSD- t test was used for pairwise comparisons between groups. Results:Compared with the control group, cell viability, the average length of mitochondria and the mitochondrial membrane potential were decreased, and ROS production, the cell apoptosis rate and LDH were increased in the LPS group (all P<0.05). After Mdivi-1 intervention, compared with the LPS-stimulated group, the cell viability was increased, myocardial cell damage was reduced, the average length of mitochondria was prolonged, mitochondrial dysfunction was alleviated, and the cell apoptosis rate was inhibited in the LPS+Mdivi-1 group (all P<0.05). Conclusions:Mdivi-1 might inhibit mitochondrial fission mediated by Drp1, maintain mitochondrial dynamic balance, alleviate mitochondrial dysfunction and protect myocardial cells from LPS-induced injury.

ABSTRACT

Objective:The risk factors and survival conditions of cardiomyopathy in childhood septic shock were retrospectively analyzed.Methods:Children with septic shock admitted to the PICU at Children′s Hospital of Chongqing Medical University from January 2015 to March 2021 were collected.The case group included children with septic shock and cardiomyopathy.The propensity score matching method was used to match children with septic shock without cardiomyopathy in a 1∶2 ratio as the control group.Basic clinical data, myocardial biomarkers, cardiac ultrasound indicators, organ function indicators and clinical outcome indicators were collected from two groups.Results:Forty-six patients were included in the case group and 92 patients in the control group.There were no significant differences in age, sex, pediatric critical care score, and basic disease between two groups.Moreover, left ventricular ejection fraction[51.0%(43.0%, 62.0%) vs.65.5%(60.6%, 69.0%)], left ventricle short-axis shortening rate (FS)[26%(21%, 33%) vs.35%(32%, 38%)], and oxygenation index(PaO 2/FiO 2)[324.0(234.3, 400.0) mmHg vs.400.0(265.8, 445.0)mmHg] in case group were lower than those in control group, while the incidence of the ST segment changes of the ECG index (21.7% vs.3.3%), lactate[3.20(1.20, 5.87)mmol/L vs.1.80(1.20, 3.40)mmol/L], and vasoactive drug score[25.14(14.84, 42.70)points vs.15.04(10.00, 26.70) points] in case group were higher than those in control group, the differences were all statistically significant (all P<0.05). The differences of PICU mortality (15.2% vs.14.1%) and 28 d mortality (29.1% vs.29.3%) between two groups were not significant ( P>0.05). The Logistic regression analysis showed that the FS was associated with cardiomyopathy occurring in septic shock[ OR (95% CI): 0.795 (0.714~0.870), P<0.001]. Children with septic shock with elevated cardiac troponin I had an increased risk of death. Conclusion:FS is an independent risk factor for cardiomyopathy in septic shock.There is no difference in survival between septic shock with and without cardiomyopathy.Cardiac troponin I is associated with the prognosis of septic shock in children.

ABSTRACT

Objective:To develop and validate a model for predicting death risk in septic shock patients using LASSO-Logistic methods.Methods:A retrospective cohort study was conducted. Based on the open-source database Medical Information Mart for Intensive Care-Ⅲ v1.4 (MIMIC-Ⅲ v1.4), the septic shock patients meeting the Sepsis-3 criteria were included, and the data on demographic characteristics, major signs, laboratory examinations, hospitalization, and outcomes were extracted. Predictive variables were selected by LASSO regression and predictive models were derived using Logistic regression. The calibration of the model was evaluated using the Hosmer-Lemeshow test and discrimination was evaluated using the receiver operator characteristic curve (ROC curve).Results:A total of 693 patients with septic shock were enrolled, in which 445 patients survived and 248 patients dead within 30 days and the mortality was 35.8%. Logistic regression model was constructed according to nine predictive variables and outcome variables screened by LASSO regression method, which showed that advanced age, Elixhauser index, blood lactic acid (Lac), K + level and mechanical ventilation were associated with increased 30-day mortality [odds ratio ( OR) and 95% confidence interval (95% CI) was 1.023 (1.010-1.037), 1.047 (1.022-1.074), 1.213 (1.133-1.305), 2.241 (1.664-3.057), 2.165 (1.433-3.301), respectively, all P < 0.01], and reduced systolic blood pressure (SBP), diastolic blood pressure (DBP), body temperature, and pulse oxygen saturation (SpO 2) were also associated with increased 30-day mortality [ OR (95% CI) was 0.974 (0.957-0.990), 0.972 (0.950-0.994), 0.693 (0.556-0.857), 0.971 (0.949-0.992), respectively, all P < 0.05]. The calibration curve showed that the predicted risk of septic shock death risk prediction model had good agreement with the real situation. ROC curve analysis showed that the area under the ROC curve (AUC) of the prediction model was 0.839 (95% CI was 0.803-0.876), which could distinguish patients at risk of death from those at risk of survival. Conclusions:The septic shock death risk prediction model has a good ability to identify the 30-day mortality risk of septic shock patients, including nine hospital readily variables (age, Elixhauser index, mechanical ventilation, Lac, K +, SBP, DBP, body temperature and SpO 2). The model could be used by clinicians to calculate the risk of death in septic shock individuals.

ABSTRACT

Lignocellulose can be hydrolyzed by cellulase into fermentable sugars to produce hydrogen, ethanol, butanol and other biofuels with added value. Pretreatment is a critical step in biomass conversion, but also generates inhibitors with negative impacts on subsequent enzymatic hydrolysis and fermentation. Hence, pretreatment and detoxification methods are the basis of efficient biomass conversion. Commonly used pretreatment methods of lignocellulose are chemical and physic-chemical processes. Here, we introduce different inhibitors and their inhibitory mechanisms, and summarize various detoxification methods. Moreover, we propose research directions for detoxification of inhibitors generated during lignocellulose pretreatment.

ABSTRACT

Objective:To investigate the incidence and risk factors of delirium after coronary artery bypass grafting(CABG) and evaluate the predictive efficacy of these risk factors.Methods:The Confusion Assessment Method for the Intensive Care Unit(CAM-ICU) was used to evaluate the incidence of delirium in 314 CABG patients. Multivariate Logsictic regression analysis was used to determine the independent risk factors for delirium after CABG.Results:The incidence of delirium after CABG was 24.8%(78/314). The incidence of delirium after CABG was 25.7%(54/210) in the training set, and 23.1%(24/104) in the validation set. American Society of Anesthesiologists Physical State≥4 points, cardiopulmonary bypass, Mini-Mental State Examination <27 points, mechanical ventilation time, postoperative midazolam application, and serum albumin <30 g/L were independent risk factors for delirium after CABG.In the training set and validation set, patients with delirium score> 2.11 were in high-risk groups, and patients with delirium score ≤2.11 were in low-risk groups.Conclusions:The established delirium predictive model can not only stratify the risk of delirium, but also provide clinical scientific basis for postoperative delirium prevention and early screening.

ABSTRACT

Sepsis is a common disease the field of critical care medicine. It is easy to be complicated by acute lung injury (ALI) or even acute respiratory distress syndrome (ARDS), which lead to high mortality. Although domestic and foreign scholars have carried out a large number of research on the pathogenesis of sepsis-related ALI/ARDS, it has not been fully elucidated so far. Recent studies have found that mitochondrial DNA (mtDNA) may play an important role in sepsis-related ALI/ARDS. This article reviews the current role of mtDNA in the pathogenesis of sepsis-related ALI/ARDS, with a view to providing new clues and evidence for the treatment of sepsis-related ALI/ARDS.

ABSTRACT

The objective of this study was to genetically characterize isolates of Giardia duodenalis and to determine if zoonotic potential of G. duodenalis could be found in stray cats from urban and suburban environments in Guangzhou, China. Among 102 fresh fecal samples of stray cats, 30 samples were collected in Baiyun district (urban) and 72 in Conghua district (suburban). G. duodenalis specimens were examined using light microscopy, then the positive specimens were subjected to PCR amplification and subsequent sequencing at 4 loci such as glutamate dehydrogenase (gdh), triose phosphate isomerase (tpi), beta-giardin (bg), and small subunit ribosomal RNA (18S rRNA) genes. The phylogenetic trees were constructed using obtained sequences by MEGA5.2 software. Results show that 9.8% (10/102) feline fecal samples were found to be positive by microscopy, 10% (3/30) in Baiyun district and 9.7% (7/72) in Conghua district. Among the 10 positive samples, 9 were single infection (8 isolates, assemblage A; 1 isolate, assemblage F) and 1 sample was mixed infection with assemblages A and C. Based on tpi, gdh, and bg genes, all sequences of assemblage A showed complete homology with AI except for 1 isolate (CHC83). These findings not only confirmed the occurrence of G. duodenalis in stray cats, but also showed that zoonotic assemblage A was found for the first time in stray cats living in urban and suburban environments in China.

ABSTRACT

This study aimed to identify the assemblages (or subassemblages) of Giardia duodenalis by using normal or nested PCR based on 4 genetic loci: glutamate dehydrogenase (gdh), triose phosphate isomerase (tpi), beta-giardin (bg), and small subunit ribosomal DNA (18S rRNA) genes. For this work, a total of 216 dogs' fecal samples were collected in Guangdong, China. The phylogenetic trees were constructed with MEGA5.2 by using the neighbor-joining method. Results showed that 9.7% (21/216) samples were found to be positive; moreover, 10 samples were single infection (7 isolates assemblage A, 2 isolates assemblage C, and 1 isolate assemblage D) and 11 samples were mixed infections where assemblage A was predominant, which was potentially zoonotic. These findings showed that most of the dogs in Guangdong were infected or mixed-infected with assemblage A, and multi-locus sequence typing could be the best selection for the genotype analysis of dog-derived Giardia isolates.
