OBJECTIVE:
To analyze the pathogenic bacterial spectrum, drug resistance, and risk factors associated with multidrug-resistant bacterial infection and mortality in patients with hematologic diseases complicated by bloodstream infections, so as to provide reference for rational drug use and improving prognosis.
METHODS:
Positive blood culture specimens of patients with hematologic diseases in two Class A tertiary hospitals of Shanxi province from January 2019 to December 2021 were retrospectively analyzed. Pathogen distribution, drug resistance and outcomes of patients with bloodstream infection were investigated, then the multivariate logistic analysis was performed to analyze the risk factors of multidrug-resistant bacterial infection and factors affecting prognosis.
RESULTS:
203 strains of pathogens were identified, mainly Gram-negative bacteria (GNB) (69.46%, 141/203), of which Escherichia coli (E.coli) had the highest incidence (41.13%, 58/141), followed by Klebsiella pneumoniae (20.57%, 29/141) and Pseudomonas aeruginosa (12.77%, 18/141). Extended-spectrum beta-lactamase (ESBL)-producing E.coli and Klebsiella pneumoniae were 46.55% (27/58) and 37.93% (11/29), respectively. Carbapenem-resistant Gram-negative bacteria accounted for 10.64% (15/141). And Gram-positive bacteria accounted for 27.59% (56/203), Staphylococcus epidermidis, Streptococcus pneumoniae, and Staphylococcus aureus were the most frequently isolated pathogen among Gram-positive bacteria (14.29%, 12.50% and 10.71%, respectively), of which methicillin-resistant Staphylococcus aureus accounted for 33.33% (2/6), coagulase-negative staphylococci accounted for 87.50% (7/8), without vancomycin- or linezolid-resistant strain. Additionally, fungi accounted for 2.95% (6/203), all of which were Candida. Multidrug-resistant Gram-negative bacteria (MDR-GNB) accounted for 53.90% (76/141). Duration of neutropenia >14 days was a risk factor for developing MDR-GNB infection. The 30-day all-cause mortality was 10.84%. Multivariate logistic regression analysis showed that the significant independent risk factors for mortality were age≥60 years (P <0.01, OR =5.85, 95% CI: 1.80-19.07) and use of vasopressor drugs (P <0.01, OR =5.89, 95% CI: 1.83-18.94).
CONCLUSION
The pathogenic bacteria of bloodstream infection in patients with hematological diseases are widely distributed, and the detection rate of multidrug-resistant bacteria is high. The clinicians should choose suitable antibiotics according to the results of bacterial culture and antibiotic susceptibility test.

PURPOSE: Colonic perforation is a lethal condition presenting high morbidity and mortality in spite of urgent surgical treatment. This study investigated the surgical outcome of patients with colonic perforation associated with retroperitoneal contamination. METHODS: Retrospective analysis was performed for 30 patients diagnosed with colonic perforation caused by either inflammation or ischemia who underwent urgent surgical treatment in our facility from January 2005 to December 2014. Patient characteristics were analyzed to find risk factors correlated with increased postoperative mortality. Using the Physiological and Operative Severity Score for the Enumeration of Mortality and Morbidity (POSSUM) audit system, the mortality and morbidity rates were estimated to verify the surgical outcomes. Patients with retroperitoneal contamination, defined by the presence of retroperitoneal air in the preoperative abdominopelvic CT, were compared to those without retroperitoneal contamination. RESULTS: Eight out of 30 patients (26.7%) with colonic perforation had died after urgent surgical treatment. Factors associated with mortality included age, American Society of Anesthesiologists (ASA) physical status classification, and the ischemic cause of colonic perforation. Three out of 6 patients (50%) who presented retroperitoneal contamination were deceased. Although the patients with retroperitoneal contamination did not show significant increase in the mortality rate, they showed significantly higher ASA physical status classification than those without retroperitoneal contamination. The mortality rate predicted from Portsmouth POSSUM was higher in the patients with retroperitoneal contamination. CONCLUSION: Patients presenting colonic perforation along with retroperitoneal contamination demonstrated severe comorbidity. However, retroperitoneal contamination was not found to be correlated with the mortality rate.

3.Prevention and treatment strategy for burn wound sepsis in children.
Chinese Journal of Burns 2016;32(2):71-73
Wound sepsis is one of the main causes of death in patients with severe burn and trauma. The high incidence of burn wound sepsis in children is attributed to their imperfect immune system function, poor resistance against infection, and the weakened skin barrier function after burn. The key to reduce the mortality of pediatric patients with burn wound sepsis is to enhance the understanding of its etiology, epidemiology, pathogenesis, and diagnostic criteria, in order to improve its early diagnosis and treatment.

4.Acute-on-chronic liver failure: a new syndrome in cirrhosis.
Clinical and Molecular Hepatology 2016;22(1):1-6
Patients with cirrhosis who are hospitalized for an acute decompensation (AD) and also have organ failure(s) are at high risk of short-term death. These patients have a syndrome called Acute-on-Chronic Liver Failure (ACLF). ACLF is now considered as a new syndrome that it is distinct from "mere" AD not only because of the presence of organ failure(s) and high short-term mortality but also because of younger age, higher prevalence of alcoholic etiology of cirrhosis, higher prevalence of some precipitants (such as bacterial infections, active alcoholism), and more intense systemic inflammatory response. ACLF is a new syndrome also because severe sepsis or severe alcoholic hepatitis do not account for 100% of the observed cases; in fact, almost 50% of the cases are of "unknown" origin. In other words, severe sepsis, severe alcoholic hepatitis and ACLF of "unknown origin" are subcategories of the syndrome.

BACKGROUND/AIMS: Patients with liver cirrhosis (LC) are at risk for critical events leading to Intensive Care Unit (ICU) admission. Coagulopathy in cirrhotic patients is complex and can lead to bleeding as well as thrombosis. The aim of this study was to investigate bleeding complications in critically ill patients with LC admitted to a medical ICU (MICU). METHODS: All adult patients admitted to our MICU with a diagnosis of LC from January 2006 to December 2012 were retrospectively assessed. Patients with major bleeding at the time of MICU admission were excluded from the analysis. RESULTS: A total of 205 patients were included in the analysis. The median patient age was 62 years, and 69.3% of the patients were male. The most common reason for MICU admission was acute respiratory failure (45.4%), followed by sepsis (27.3%). Major bleeding occurred in 25 patients (12.2%). The gastrointestinal tract was the most common site of bleeding (64%), followed by the respiratory tract (20%). In a multivariate analysis, a low platelet count at MICU admission (odds ratio [OR], 0.98; 95% confidence interval [CI], 0.97 to 0.99) and sepsis (OR, 8.35; 95% CI, 1.04 to 67.05) were independent risk factors for major bleeding. The ICU fatality rate was significantly greater among patients with major bleeding (84.0% vs. 58.9%, respectively; p = 0.015). CONCLUSIONS: Major bleeding occurred in 12.2% of critically ill cirrhotic patients admitted to the MICU. A low platelet count at MICU admission and sepsis were associated with an increased risk of major bleeding during the MICU stay. Further study is needed to better understand hemostasis in critically ill patients with LC.

Korean Journal of Otolaryngology - Head and Neck Surgery 2016;59(9):668-671
BACKGROUND AND OBJECTIVES: Esophageal perforation is relatively uncommon and requires careful diagnostic evaluation and expert management. It has a high mortality due to significant mediastinal and pleural contamination leading to sepsis and multiple organ failure. We reviewed our experience of esophageal perforation to determine how to better recognize such a lesion and facilitate its correct management. SUBJECTS AND METHOD: A retrospective chart review was performed on all patients treated for esophageal perforation from January 2000 to March 2016. These patients have been studied with respect to gender and age distribution, causes, sites, clinical manifestation, complications, management and postoperative complications. RESULTS: Patients ranged in age from 21 to 87 years, with an average age of 57.6±12.4 years. Fifty of the patients were men and 21 were women. The causes of the perforations were as follows: foreign body retention (18 patients), trauma (17 patients), Boerhaave's syndrome (22 patients), and iatrogenic (14 patients). The sites of esophageal perforation were: the cervical esophagus (25 patients), thoracic esophagus (44 patients) and abdominal esophagus (2 patients). Primary repair only was performed in seven (9.9%) patients, whereas 32 (45%) patients were treated with primary repair & patch, seven (9.9%) patients with T-tube drainage. Exclusion & division were performed in three (4.2%) patients and esophagectomy was performed in two (2.8%) patients. Twenty (28.2%) patients were treated conservatively. CONCLUSION: Early recognition and appropriate management of esophageal perforation are essential for reduction of morbidity and mortality.

BACKGROUND: Dysfunctional natural anticoagulant systems enhance intravascular fibrin for mation in disseminated intravascular coagulation (DIC), and plasma levels of natural anti coagulants can be used in the diagnosis and prognosis of DIC. Herein, the diagnostic value of 4 natural anticoagulants was assessed, and the prognostic value of antithrombin and protein C were validated in a large population. METHODS: Part 1 study included 126 patients with clinically suspected DIC and estimated plasma levels of 4 candidate anticoagulant proteins: antithrombin, protein C, protein S, and protein Z. Part 2 comprised 1,846 patients, in whom plasma antithrombin and protein C levels were compared with other well-known DIC markers according to the underlying dis eases. The 28-day mortality rate was used to assess prognostic outcome. RESULTS: Antithrombin and protein C showed higher areas under the ROC curve than pro tein S and protein Z. In part 2 of the study, antithrombin and protein C levels significantly correlated with DIC score, suggesting that these factors are good indicators of DIC severity. Antithrombin and protein C showed significant prognostic power in Kaplan-Meier analyses. In patients with sepsis/severe infection, antithrombin and protein C showed higher hazard ratios than D-dimer. Platelet count showed the highest hazard ratio in patients with hemato logic malignancy. In patients with liver disease, the hazard ratio for antithrombin levels was significantly high. CONCLUSIONS: Decreased plasma anticoagulant levels reflect florid consumption of the phys iologic defense system against DIC-induced hypercoagulation. Plasma antithrombin and protein C levels are powerful prognostic markers of DIC, especially in patients with sepsis/severe infection.

OBJECTIVETo explore the epidemiological characteristics of inhalation injury and to summarize the clinical application experience of diagnostic standard of burn of larynx.
METHODSMedical records of 443 patients with inhalation injury admitted to our burn unit from January 1999 to June 2013 were analyzed, including gender, age, severity of inhalation injury, complications and diseases before injury; total area and that of full-thickness burn injury, admission time after burn, and burn condition of larynx of patients with different degrees of inhalation injury; treatment and outcome including rate, time, and complication of tracheotomy, mortality, and cause of death. Data were processed with nonparametric Kruskal-Wallis test and chi-square test. The relationship between severity of inhalation injury and total burn area, degree of burn of larynx, tracheotomy rate, and mortality was assessed by Spearman correlation analysis.
RESULTS(1) Among the patients, there were 353 (79.7% ) male and 90 (20.3% ) female, with the ratio of male to female 4:1. There were 64 (14.4%) patients younger than or equal to 20 years, 203 (45.8%) patients older than 20 years and younger than or equal to 40 years, 144 (32.5%) patients older than 40 years and younger than or equal to 60 years, and 32 (7.2%) patients older than 60 years. The numbers of patients with mild, moderate, and severe inhalation injury were respectively 297, 108, and 38. Seven patients suffered from complications, and 21 patients had diseases before injury. There were statistically significant differences among the patients with different degree of inhalation injury in regard to total burn area and full-thickness burn area (with H values respectively 73.752 and 142.830, P values below 0.01), while no statistically significant difference was observed in admission time after burn ( H = 1.528, P > 0.05). Correlation analysis showed that severity of inhalation injury was positively correlated with total burn area (r = 0.399, P < 0.001). Among the patients with mild inhalation injury, incidences of patients with mild, moderate, and severe burn of larynx were respectively 68.0% (202/297), 32.0% (95/297), and 0, and those among the patients with moderate inhalation injury were respectively 0,53.7% (58/108), and 46.3% (50/108). There were statistically significant differences in degree of burn of larynx of patients with different degree of inhalation injury (χ2 = 336.703, P < 0.001). Correlation analysis showed that severity of burn of larynx was positively correlated with severity of inhalation injury (r = 0.700, P < 0.001). (2) The rate of tracheotomy was 37.02% (164/443). The rates of tracheotomy in patients with mild, moderate, and severe inhalation injury were respectively 10.44% (31/297), 87.96% (95/108), and 100.00% (38/38), χ2 = 271.654, P < 0.001. Correlation analysis showed that the rate of tracheotomy was positively correlated with severity of inhalation injury (r = 0.784, P < 0.001). Tracheotomy was done mainly within 6 h post burn (63.4%, 104/164). The incidence rate of complication of tracheotomy was 5.5% (9/164). (3) Thirty-one patients died, with a mortality rate of 7.00%. The mortality rates of patients with mild, moderate, and severe inhalation injury were respectively 1.01% (3/297), 12.96% (14/108), and 36.84% (14/38), H = 74.273, P < 0.001. It was found that the mortality was positively correlated with severity of inhalation injury (r = 0.371, P < 0.001). The causes of death of the patients were respectively sepsis (14, 45.2%), respiratory failure (7, 22.6%), airway obstruction (2, 6.5%), airway hemorrhage (2, 6.5%), cerebral hemorrhage (2, 6.5%), cardiac accident (2, 6.5%), and diabetes insipidus (1, 3.2%), and 1 (3.2%) patient quit treatment and discharged from hospital for economic reason.
CONCLUSIONSAmong the patients with inhalation injury, male is dominated in number, and the young adults formed the highest constituent ratio. The severity of inhalation injury was correlated with total burn area, severity of burn of larynx, tracheotomy rate, and mortality. With the guidance of diagnostic criteria of burn of larynx and indication of tracheotomy, the risk of laryngeal obstruction can be eliminated. The early preventive tracheotomy can decrease the difficulty and risk of the operation.

PURPOSE: The aim of this study was to investigate clinical characteristics and risk factors of acute kidney injury (AKI) in patients with sepsis and septic shock. Additionally, we explored whether the severity of AKI affects on the clinical outcomes. MATERIALS AND METHODS: Data were collected retrospectively in a single center. Among 5680 patients who visited emergency department from January to December 2010, 992 patients with sepsis and septic shock were enrolled. Patients were divided into two groups, patients who developed AKI or not, to compare the baseline characteristics, and laboratory and physiologic data. Patients with AKI were subdivided according to its stages for survival analysis. RESULTS: AKI was developed in 57.7% of patients. Multivariable logistic regression analysis revealed that development of septic AKI was associated with older age, pre-existing chronic kidney disease, use of angiotensin converting enzyme inhibitor or angiotensin receptor blocker, presence of shock, positive blood culture results, and low white blood cell and platelet counts. Hospital mortality was higher in AKI group. Crude Kaplan-Meier survival curves demonstrated reduced 30-day survival rate was significantly associated with the severity of acute kidney injury. CONCLUSION: The development of septic AKI was associated with poor clinical outcomes. Furthermore, the severity of AKI was associated with increased mortality.

OBJECTIVETo study risk factors for the occurrence of intra-abdominal hypertension (IAH) in children with sepsis.
METHODSA nest case-control study was employed. According to intra-abdominal pressures (IAP) measured by cystometry, 119 children with sepsis were classified into normal IAP (control, n = 80) and IAH groups (n = 39). Risk factors for the occurrence of IAH were investigated by monovariable and multivariable logistic regression analysis.
RESULTSMonovariable analysis showed that there were significant differences in pediatric critical illness score (PCIS), procalcitonin (PCT) level, PaCO(2), blood lactate level, rates of intestinal or intra-abdominal infection, ascites, gastrointestinal dysfunction, mechanical ventilation, shock and multiple organ dysfunction syndrome (MODS) between the IAH and control groups (P < 0.05). Multivariable logistic regression analysis demonstrated that decreased PCIS, MODS, shock, gastrointestinal dysfunction and ascites were major risk factors for the occurrence of IAH.
CONCLUSIONSChildren with sepsis who have decreased PCIS, MODS, shock, gastrointestinal dysfunction and ascites are at risk for the occurrence of IAH.
