Abstract
Basic research suggests some contributing mechanisms underlying asthma might at the same time benefit patients with asthma against sepsis, while the potential protective effect of comorbid ...asthma on prognosis of sepsis has not been well studied in clinical research. The study aimed to assess the association between comorbid asthma and prognosis in a cohort of patients admitted to intensive care unit (ICU) with severe sepsis. Patients with severe sepsis admitted to ICUs were included from the MIMIC-III Critical Care Database, and categorized as patients without asthma, patients with stable asthma, and patients with acute exacerbation asthma. The primary study outcome was 28-day mortality since ICU admission. Difference in survival distributions among groups were evaluated by Kaplan–Meier estimator. Multivariable Cox regression was employed to examine the association between comorbid asthma and prognosis. A total of 2469 patients with severe sepsis were included, of which 2327 (94.25%) were without asthma, 125 (5.06%) with stable asthma, and 17 (0.69%) with acute exacerbation asthma. Compared with patients without asthma, patients with asthma (either stable or not) had a slightly younger age (66.73 ± 16.32 versus 64.77 ± 14.81 years), a lower proportion of male sex (56.81% versus 40.14%), and a lower median SAPS II score (46 versus 43). Patients with acute exacerbation asthma saw the highest 28-day mortality rate (35.29%), but patients with stable asthma had the lowest 28-day mortality rate (21.60%) when compared to that (34.42%) in patients without asthma. Consistent results were observed in Kaplan–Meier curves with a p-value for log-rank test of 0.016. After adjusting for potential confounding, compared to being without asthma, being with stable asthma was associated with a reduced risk of 28-day mortality (hazard ratio (HR) 0.65, 95% confidence interval (CI) 0.44–0.97, p = 0.0335), but being with acute exacerbation asthma was toward an increased risk of 28-day mortality (HR 1.82, 95% 0.80–4.10, p = 0.1513). E-value analysis suggested robustness to unmeasured confounding. These findings suggest comorbid stable asthma is associated with a better prognosis in critically ill patients with severe sepsis, while acute exacerbation asthma is associated with worse prognosis.

Introduction The speckle tracking ultrasound is an innovative technology enabling distinct assessment of diaphragmatic movement, yet the relative data are scarce. In this pilot study, we sought to ...evaluate the predictive value of the weaning outcome of automatic speckle tracking in assessing diaphragm excursion. Methods This is a prospective, multicenter, observational study. A total of 160 critically ill subjects underwent speckle-tracking ultrasonography of the right/left hemidiaphragm before the spontaneous breathing trial. Meanwhile, the diaphragm excursion and velocity values were measured manually by M-mode ultrasound. Patients were divided into weaning-failure and weaning-success groups. The correlation was assessed between automatic and manual measurement, and the diagnostic efficacy of automatic measured excursion and velocity for predicting weaning outcome was analyzed. Results A total of 88 patients completed the follow-up of the weaning outcome. The overall incidence of weaning failure was 43.18%. There was a significant correlation between the automatic measurement of mean excursion and velocity assessed by speckle tracking imaging and manual measurement (R 0.69 and 0.65, respectively). Receiver operating characteristic (ROC) curve analysis showed that the mean excursion and diaphragmatic velocity exhibited high diagnostic values for prolonged weaning area under the ROC curve (AUROC) 0.824 and 0.786, respectively. The diaphragmatic excursion showed moderate diagnostic value for predicting both weaning failure and in-hospital death/withdrawal of treatment (AUROC 0.659 and 0.653, respectively). Conclusion Automatic speckle tracking analysis of the diaphragm showed high consistency with conventional manual ultrasound measures. Diaphragmatic excursion and its excursion velocity helped predict mechanical ventilation weaning failure, prolonged weaning, as well as in-hospital adverse outcomes, which served as a reliable tool in guiding clinical weaning strategy. Key message Automatic speckle tracking analysis of the diaphragm showed high consistency with conventional manual ultrasound measures. Diaphragmatic excursion and its excursion velocity helped predict mechanical ventilation weaning failure, prolonged weaning, as well as in-hospital adverse outcomes.

•Initial levels of HMGB-1 were observed to be significantly higher in septic patients who perished within 30 days, compared to those who survived.•Pooled results failed to demonstrate a significant ...association of HMGB-1 concentrations at admission with mortality of more severe sepsis, mostly septic shock.•A stronger correlation between blood HMGB-1 levels on day 3 after admission and fatal cases of sepsis was suggested.•HMGB-1 can be used for guiding sepsis management in the clinical setting.
The role of blood high mobility group box-1 (HMGB-1) protein in predicting mortality of sepsis remains controversial.
Here we conducted a meta-analysis to seek evidence for the association between blood HMGB-1 concentrations and mortality in patients with sepsis.
Eligible studies were identified by a comprehensive search of six digital databases, supplemented by a manual search of related references. Standardized mean differences (SMDs) and corresponding 95% confidence intervals (CIs) were calculated as effect estimates.
A total of eighteen studies, covering 1163 patients with sepsis, were included. Compared with survival groups of sepsis, non-survival groups had significantly higher blood HMGB-1 concentrations at enrollment (SMD: 0.45, 95% CI: 0.21–0.69). Subgroup analyses showed that no significant differences were found between two groups among patients with more severe sepsis (SMD: 0.18, 95% CI: -0.02–0.38). A significant association between initial HMGB-1 levels and ≤30-day mortality remained (SMD: 0.43, 95% CI: 0.09–0.78). Besides, HMGB-1 levels were observed to be more significantly higher in non-survival groups after the third day of admission (SMD: 1.33, 95% CI: 1.05–1.62) but two groups attained comparable HMGB-1 levels on day 7 (SMD: 1.01, 95% CI: -0.31–2.33).
Initial high blood HMGB-1 levels are significantly associated with short-term (≤30 days) mortality of patients with sepsis, and the association may be affected by the severity of sepsis. Subsequent monitoring of HMGB-1 levels, on the third and seventh day after admission, is encouraged for better evaluation of HMGB-1 as a prognostic marker of mortality in sepsis.

Mechanical ventilation (MV) is an important lifesaving method in intensive care unit (ICU). Prolonged MV is associated with ventilator associated pneumonia (VAP) and other complications. However, ...premature weaning from MV may lead to higher risk of reintubation or mortality. Therefore, timely and safe weaning from MV is important. In addition, identification of the right patient and performing a suitable weaning process is necessary. Although several guidelines about weaning have been reported, compliance with these guidelines is unknown. Therefore, the aim of this study is to explore the variation of weaning in China, associations between initial MV reason and clinical outcomes, and factors associated with weaning strategies using a multicenter cohort.
This multicenter retrospective cohort study will be conducted at 17 adult ICUs in China, that included patients who were admitted in this 17 ICUs between October 2020 and February 2021. Patients under 18 years of age and patients without the possibility for weaning will be excluded. The questionnaire information will be registered by a specific clinician in each center who has been evaluated and qualified to carry out the study.
In a previous observational study of weaning in 17 ICUs in China, weaning practices varies nationally. Therefore, a multicenter retrospective cohort study is necessary to be conducted to explore the present weaning methods used in China.

To improve the occupational health management levels in electroplating enterprises with quantitative classification measures and to provide a scientific basis for the prevention and control of ...occupational hazards in electroplating enterprises and the protection of workers' health.
A quantitative classification table was created for the occupational health management in electroplating enterprises. The evaluation indicators included 6 items and 27 sub-items, with a total score of 100 points. Forty electroplating enterprises were selected and scored according to the quantitative classification table. These electroplating enterprises were classified into grades A, B, and C based on the scores.
Among 40 electroplating enterprises, 11 (27.5%) had scores of >85 points (grade A), 23 (57.5%) had scores of 60∼85 points (grade B), and 6 (15.0%) had scores of <60 points (grade C).
Quantitative classification management for electroplating enterprises is a valuable attempt, which is helpful for the supervision and managem
