Objective: Compelling evidence has shown that aggressive resuscitation bundles are one of the cornerstones of the successful treatment of patients with sepsis. Recent studies suggest that lactate normalization during resuscitation is a more powerful indicator of resuscitative adequacy; however, early lactate clearance-guided therapy is still not recommended. We performed this meta-analysis to evaluate the effect of early lactate clearance-directed therapy as a potentially more effective resuscitation target. Methods: Studies were identified using PubMed, Embase, and the Cochrane Library without region, publication type, or language restrictions. Randomized trials were included when they compared the efficacy and safety of lactate clearance-guided resuscitation versus central venous oxygen saturation (ScvO₂)-guided therapy. The primary outcome was mortality, and the secondary outcomes were intensive care unit (ICU) stay, length of hospital stay, mechanical ventilation time, Acute Physiology and Chronic Health Evaluation-II (APACHE-II) score, and Sepsis-related Organ Failure Assessment (SOFA) score. Results: Seven randomized controlled trials encompassing 1301 cases were reviewed. Compared with guided ScvO₂ therapy, early lactate clearance-directed therapy was associated with decreased in-hospital mortality (relative ratio [RR] 0.68, 95% confidence interval [CI] 0.56 to 0.82), shorter ICU stay (mean difference [MD] −1.64 days, 95% CI −3.23 to −0.05), shorter mechanical ventilation time (MD −10.22 hours, 95% CI −15.94 to −4.5), and lower APACHE-II scores (MD −4.47, 95% CI −7.25 to −1.69). However, patients undergoing early lactate clearance-guided therapy had similar lengths of hospital stay and similar SOFA scores. Conclusions: As a specific indicator of resuscitation outcome, lactate clearance alone is superior to ScvO₂ alone during a standard resuscitation paradigm. The optimal or desired rate of lactate clearance is still a contentious area. To guide resuscitation and normalize lactate levels in patients, repeating lactate measurements every 2 hours until the patient has met a lactate clearance of 10% or greater may be helpful.

To compare the ability of thyroid hormones, IL-6, IL-10, and albumin to predict mortality, and to assess their relationship in case-mix acute critically ill patients. APACHE II scores and serum thyroid hormones (FT3, FT4, and TSH), IL-6, IL-10, and albumin were obtained at EICU admission for 79 cases of mix acute critically ill patients without previous history of thyroid disease. Patients were followed for 28 days with patient's death as the primary outcome. All mean values were compared, correlations assessed with Pearson' test, and mortality prediction assessed by multivariate logistic regression and ROC. Non survivors were older, with higher APACHE II score (p=0.000), IL-6 (p<0.05), IL-10 (p=0.000) levels, and lower albumin (p=0.000) levels compared to survivors at 28 days. IL-6 and IL-10 had significant negative correlation with albumin (p=0.001) and FT3 (p ⩽ 0.05) respectively, while low albumin had a direct correlation with FT3 (p<0.05). In the mortality prediction assessment, IL-10, albumin and APACHE II were independent morality predictors and showed to have a good (0.70-0.79) AUC-ROC (p<0.05). Despite that the entire cohort showed low FT3 serum levels (p=0.000), there was not statistical difference between survivors and non-survivors; neither showed any significance as mortality predictor. IL-6 and IL-10 are correlated with Low FT3 and hypoalbuminemia. Thyroid hormones assessed at EICU admission did not have any predictive value in our study. And finally, high levels of IL-6 and IL-10 in conjunction with albumin could improve our ability to evaluate disease's severity and predict mortality in the critically ill patients. When use in combination with APACHE II scores, our model showed improved mortality prediction.

Purpose: To determine the clinical manifestations and results of adult hemophagocytic lymphohistiocytosis (HLH) patients in our emergency department. Methods: We retrospectively evaluated patients with HLH from 1 April 2018 to 31 December 2020. The clinical data of these patients (basic information, symptoms, vital signs, laboratory results, HLH diagnostic criteria, H Score, main treatments, outcomes) were collected. Results: Thirty-three patients (23 males and 10 females; 40.55± 18.78 years) with 34 clinical episodes (one male had two clinical episodes and died during the second episode) were enrolled. Twenty-five patients were placed in a “survivor” group, and nine patients were categorized into a “deceased” group. Fever, splenomegaly, hemoglobin < 90 g/L and platelet count < 100× 10⁹/L most commonly met the diagnostic standard for HLH. The H Score results in the survival group and deceased group was 212.4± 37.18 and 252.1± 40.95, respectively. Viral infection was the most common reason for HLH, followed by immune-system disease and cancer. Laboratory tests showed that deceased-group patients had multiple-organ dysfunction. Multivariate logistic regression showed that the lactate dehydrogenase (lactate dehydrogenase) level (P = 0.039; odds ratio, 0.999) was significantly related to death. Conclusion: In the emergency department, HLH should be considered for critically ill patients with fever, splenomegaly, low hemoglobin and low platelet count. The H Score might be useful to diagnose HLH quickly. In our study, 26.47% of HLH patients died in the emergency department, and patients with a significantly increased lactate dehydrogenase level had a markedly increased risk of death.

Objectives: Our goal in this study was to determine 1) whether there are any differences in clinical characteristics between Chinese and Western patients with aortic dissection (AD), and 2) the mortality rate of AD patients in the emergency department (ED) and identify the risk predictors for death.Methods: We retrospectively analyzed patients who were diagnosed with AD and admitted to our ED between September 1, 2017–August 31, 2020. Data on age, gender, clinical manifestation, medical history, routine blood tests, liver and kidney function, coagulation, myocardial enzymology, and mortality were collected.Results: We enrolled 535 AD patients (422 men and 113 women) with a mean age of 54.7±14.1 years. Type A AD constituted 40% of the total number of AD cases, while type B AD constituted 60%. The proportion of those who were females, 10-92 years, with type A AD, and hypertension in the Chinese population was lower than that in the Western population (P <0.05 for all). Type A AD patients had a higher proportion of acute AD clinical manifestations than did patients with type B AD (P = 0.0084, P <0.05). The mortality rate of type A AD patients (10.75%) was higher than that of type B AD patients (1.87%) (P <0.0001) in the ED. Higher values of white blood cells, neutrophils, high-density lipoprotein, activated partial thromboplastin time, and D-dimer level with worsened hepatic and renal function were found in the deceased group, and multivariate logistic regression revealed that blood urea nitrogen (BUN) levels (P = 0.0031, P <0.05) were significantly associated with death.Conclusion: In South China, patients with AD had a mean age of 54.7 years, with 78.88% prevalence in males and 66.92% hypertension rate. Type A AD accounted for 40% of all AD cases, and 10.70% of patients with type A AD died in the ED. Elevated BUN levels may be a risk predictor for death in patients with type A AD.

In the end of 2019, the epidemic of a new coronavirus (SARS-CoV-2) occurred in Wuhan and spread rapidly. Changsha, a city located south to the epicenter, was soon impacted. To control the transmission of the coronavirus and avoid nosocomial infection, triage procedures based on epidemiology were implemented in a local hospital of the city. This retrospective study analyzed the data collected during the triage period and found that COVID-19 patients were enriched seven folds into the Section A designated for rapid detection and quarantine. On the other side, roughly triple amounts of visits were received at the Section B for patients without obvious epidemiological history. Eight COVID-19 cases were spotted out of 247 suspected patients. More than 50% of the suspected patients were submitted to multiple rounds of nucleic acid analysis for SARS-CoV-2 infection. Of the 239 patients who were diagnosed as negative of the virus infection,188 were successfully revisited and none was reported as a COVID-19 case. Of the eight COVID-19 patients, three were confirmed only after multiple rounds of nucleic acid analysis. Besides comorbidities, delayed sharing of epidemiological history added another layer of complexity to the diagnosis in practice. While SARS-CoV-2 epidemic is being alerted in many countries, our report will be helpful to other colleagues in rapid identification of COVID-19 cases and controlling the transmission of the disease.
