Objective To verify the relationship between catheter-related urinary tract infection(CAUTI)and stress hyperglycemia during catheter retention in stroke patients. Methods We used nosocomial infection monitoring system to track the status of CAUTI in stroke patients in a hospital.The study cohort was all the patients who received retention catheterization from January 2016 to March 2020.According to the nested case-control design,multivariate logistic regression analysis was performed to explore the relationship between stress hyperglycemia and CAUTI in stroke patients with indwelling catheter. Results A total of 322 cases of CAUTI and 644 cases of non-CAUTI were enrolled in this study.The length of stay in the case group was(20.68 ± 3.73)d,significantly longer than that[(13.00 ± 4.01)d]in the control group(t=29.473,P <0.001).Compared with non-stress hyperglycemia,stress hyperglycemia posed a higher risk of CAUTI in the stroke patients with indwelling catheter(OR=2.020,95% CI=1.447-2.821,P=0.000)and led to the higher incidence of CAUTI in one thousand days(P<0.001). Conclusion Stress hyperglycemia in the stroke patients with indwelling catheter can significantly increase the risk of CAUTI.

Mahuang Fuzi Xixin Decoction recorded in Treatise on Febrile Diseases by Zhang Zhongjing in the Han Dynasty have been widely used in treating Yang deficiency and exogenous wind-cold syndrome by traditional Chinese medicine physicians for thousands of years. The indications of Mahuang Fuzi Xixin Decoction include bradyarrhythmia,sinus bradycardia,sick sinus node syndrome,senile exogenous,asthmatic cold,rhinitis,bronchial asthma,optic neuritis,optic atrophy,sudden blindness,sudden onset of cough,laryngeal obstruction,migraine,joint pain,low back pain,insomnia,shock,heart failure,renal failure,accompanied by fever or nosocomial infection,and hyperpyrexia after tracheotomy; dark complexion,chills,cold limbs,listlessness,fatigue,insomnia,lack of thirst,liking hot drinks,slightly swollen limbs or whole body,pale fat tongue,greasy fur,and deep pulse. Mahuang Fuzi Xixin Decoction is a potential drug for Shaoyin disease complicated with fever and pain. Tracheal intubation is an artificial ephedrine syndrome. It is necessary to distinguish Yin and Yang syndrome in treating hyperpyrexia after tracheotomy. However,it belongs to Yin syndrome,which could be treated by Mahuang Fuzi Xixin Decoction. Mahuang Fuzi Xixin Decoction is effective in the treatment of sick sinus syndrome,second degree atrioventricular block and third degree atrioventricular block. It can significantly alleviate symptoms,improve heart rate,and heart rhythm in a short period of time. However,after one year of drug withdrawal,the diseases may recur,indicating that Mahuang Fuzi Xixin Decoction may not improve the long-term prognosis of slow arrhythmia. Mahuang Fuzi Xixin Decoction is often used for fever or nosocomial infection in critical care medicine. In the treatment of critical care medicine complicated with high fever,Mahuang Fuzi Xixin Decoction is often taken continuously by stomach tube.

OBJECTIVE: To determine the incidence of surgical site infection (SSI) after abdominal surgery and to further evaluate the related risk factors of SSI in China. METHODS: The multicenter cross-sectional study collected clinical data of all adult patients who underwent abdominal surgery from May 1, 2018 to May 31, 2018 in 30 domestic hospitals, including basic information, perioperative parameters, and incisional microbial culture results. The primary outcome was the incidence of SSI within postoperative 30 days. SSI was classified into superficial incision infection, deep incision infection, and organ/gap infection according to the US Centers for Disease Control and Prevention (CDC) criteria. The secondary outcome variables were ICU stay, postoperative hospital stay, total hospital stay, 30-day mortality and treatment costs. Multivariate logistic regression was used to analyze the risk factors of SSI. RESULTS: A total of 1666 patients were enrolled in the study, including 263 cases of East War Zone Hospital of PLA, 140 cases of Affiliated Hospital of Qingdao University, 108 cases of The First Affiliated Hospital of Nanchang University, 87 cases of Central War Zone Hospital of PLA, 77 cases of West China Hospital, 74 cases of Guangdong General Hospital, 71 cases of Chenzhou First People's Hospital, 71 cases of Zigong First People's Hospital, 64 cases of Zhangjiagang First People's Hospital, 56 cases of Nanyang City Central Hospital, 56 cases of Lanzhou General Hospital of Lanzhou Military Command, 56 cases of Shandong Provincial Hospital, 52 cases of Shangqiu First People's Hospital, 52 cases of People's Hospital of Xinjiang Uygur Autonomous Region, 48 cases of The Second Xiangya Hospital of Central South University, 48 cases of Chinese PLA General Hospital, 44 cases of Affiliated Hospital of Xuzhou Medical University, 38 cases of Hunan Province People's Hospital, 36 cases of Dongguan Kanghua Hospital, 30 cases of Shaoxing Central Hospital, 30 cases of Northern Jiangsu People's Hospital, 29 vases of The First Affiliated Hospital of Zhengzhou University, 27 cases of General Hospital of Tianjin Medical University, 22 cases of Zigong Fourth People's Hospital, 21 cases of The Second Hospital of University of South China, 18 cases of Tongji Hospital, 15 cases of Nanchong Central Hospital, 12 cases of The 901th Hospital of PLA, 11 cases of Hunan Cancer Hospital, 10 cases of Lanzhou University Second Hospital. There were 1019 males and 647 females with mean age of (56.5±15.3) years old. SSI occurred in 80 patients (4.8%) after operation, including 39 cases of superficial incision infection, 16 cases of deep incision infection, and 25 cases of organ/interstitial infection. Escherichia coli was the main pathogen of SSI, and the positive rate was 32.5% (26/80). Compared with patients without SSI, those with SSI had significantly higher ICU occupancy rate [38.8%(31/80) vs. 13.9%(220/1586), P<0.001], postoperative hospital stay (median 17 days vs. 7 days, P<0.001) and total hospital stay (median 22 days vs. 13 days, P<0.001), and significantly higher cost of treatment (median 75 000 yuan vs. 44 000 yuan, P<0.001). Multivariate analysis showed that male rise(OR=2.110, 95%CI:1.175-3.791, P=0.012), preoperative blood glucose level rise(OR=1.100, 95%CI: 1.012-1.197, P=0.026), operative time (OR=1.006, 95%CI:1.003-1.009, P<0.001) and surgical incision grade (clean-contaminated incision:OR=10.207, 95%CI:1.369-76.120, P=0.023; contaminated incision: OR=10.617, 95%CI:1.298-86.865, P=0.028; infection incision: OR=20.173, 95%CI:1.768-230.121, P=0.016) were risk factors for SSI; and laparoscopic surgery (OR=0.348, 95%CI:0.192-0.631, P=0.001) and mechanical bowel preparation(OR=0.441,95%CI:0.221-0.879, P=0.020) were protective factors for SSI. CONCLUSIONS The incidence of postoperative SSI in patients with abdominal surgery in China is 4.8%. SSI can significantly increase the medical burden of patients. Preoperative control of blood glucose and mechanical bowel preparation are important measures to prevent SSI.

OBJECTIVE: To explore the relationship between allogeneic transfusion and hospital infections in patients with closed traumatic brain injury in the perioperative period.
 METHODS: The clinical data of 181 patients with open brain surgery suffering closed brain injury in Changsha Central Hospital from February, 2012 to December, 2013 were retrospectively collected. The patients were divided into a mild and moderate brain injury group (n=83) and a severe brain injury group (n=98) according to evaluation system of Glasgow coma scale (GCS). They were also divided into a autologous transfusion plus mild and moderate brain injury group (n=14), a autologous transfusion plus severe brain injury group (n=10); an allogeneic transfusion plus mild and moderate brain injury group (n=31), an allogeneic transfustion plus severe brain injury group (n=70); a non-transfusion plus mild and moderate brain injury group (n=38) and a non-transfusion plus severe brain injury group (n=18) according to the transfusion styles. The hospital infection of all the patients was examined.
 RESULTS: The rate of hospital infection was significantly higher in the severe brain injury group than that in the mild and moderate brain injury group (P<0.05). The rate of post-operative hospital infection in the allogeneic transfusion plus severe brain injury group was also significantly higher than that in the autologous transfusion plus severe brain injury group (P<0.05). Similarly, the rate of post-operative hospital infection in the allogeneic transfusion plus mild and moderate brain injury group is higher than that in the non-transfusion plus mild and moderate brain injury group (P<0.05).
 CONCLUSION The allogeneic transfusion at perioperative period may be one of the risk factors for post-operative hospital infection in the closed brain injury patients. The more severe the injury is, the higher risk the hospital infection will be.

BACKGROUND/AIMS: As the incidence rate of and mortality from pseudomembranous colitis (PMC) are increasing worldwide, it is important to study the simple predictive risk factors for PMC among patients with hospital-acquired diarrhea (HAD). This study focused on identifying the clinical risk factors that can easily predict PMC. METHODS: The presumed HAD patients were prospectively recruited at the Hallym University Kangdong Sacred Heart Hospital. RESULTS: Age of 70 and older (adjusted odds ratio [OR], 1.76; 95% confidence interval [CI], 1.12 to 0.75), use of proton pump inhibitors (adjusted OR, 4.07; 95% CI, 2.512 to 6.57), use of cephalosporins (adjusted OR, 2.99; 95% CI, 1.82 to 4.94), and underlying cancer (adjusted OR, 1.72; 95% CI, 1.04 to 2.82) were independent risk factors for PMC in the multivariate logistic regression analysis. The prevalence of PMC was very low in the patients with HAD who exhibited no risk factors. CONCLUSIONS: The risk factors for PMC in patients with HAD included cephalosporin use, proton pump inhibitor use, old age, and cancer. Considering the strongly negative predictive values of these risk factors, endoscopic evaluation can be delayed in patients with HAD without risk of developing PMC.

OBJECTIVETo investigate the incidence, pathogens, and clinical features of infection in consecutive cases from 2010 to 2012 in Peking Union Medical College Hospital.

METHODThe incidence, pathogen, treatment, and outcomes of patients with hematological diseases who had positive findings of bacterium in their samples from 2010 to 2012 were retrospectively analyzed.

RESULTSThere were 449 positive samples (5.8%) from 4 890 patients during this period, among which 388 were proved to be with pathogenic bacteria. Samples separated from patients with community-aquired infections accounted for 8.4% of all positive samples. Most community-aquired infections were caused by Gram-negative bacteria (75%), although no multidrug-resistant bacteria was observed. Samples separated from patients with nosocomial infections accounted for 91.6% of all positive samples. Respiratory tract (49.4%) and peripheral blood (32.6%) were the most common samples with positive results. Skin soft tissues (10.4%), and urine (3.7%) were less common samples. Most of the pathogenic bacteria of the nosocomial infections were Gram-negative (66.9%). The most common Gram-negative bacteria included Escherichia coli (13.8%), Pseudomonas aeruginosa (12.1%), and Klebsiella pneumonia (12.1%), while Staphylococcus aureus (10.4%), Enterococcus faecium (7.0%), and Staphylococcus epidermidis (5.1%) were the most common Gram-positive bacteria. Gram-negative bacteria consisted of most of sputum samples and peripheral blood samples. Samples from the surface of skin wound and anal swab were composed largely by Gram-positive bacteria (63.8%). The detection rates of extended-spectrum beta-lactamase-producing Klebsiella pneumonia/Klebsiella oxytoca, Escherichia coli, and Proteus mirabilis were 24.0%, 87.9% and 38.4%, respectively. The resistance to Acinetobacter baumannii was serious. Multidrug-resistant, extensive drug resistant and pan drug resistant A. baumannii acountted for 74% of all A. Baumannii infections. Stenotrophomonas maltophilia showed low resistance to sulfamethoxazole/trimethoprim, levofloxacin and minocycline. Also, 22 methicillin-resistant Staphylococcus aureus and 9 methicillin-resistant Staphylococcus Epidermidis were detected, which were only sensitive to vancomycin, teicoplanin, and linezolid. All patients were treated in the haematology wards and most of them were under agranulocytosis or immunosuppression. Finally, 22 patients reached clinical recovery through anti-infective therapy, whereas 49 patients died. Among those deaths, 42 patients attributed to severe infections and infection-associated complications. Fourteen of all the deaths might be infected with drug-resistance bacteria. There were 61 samples proved to be bacteria colonization. Nonfermenters such as Acinetobacter baumannii and Stenotrophomonas maltophilia made up for a large amount of bacteria colonization.

CONCLUSIONSThe pathogens of nosocomial infections in the hematology ward are mainly Gram-negative bacteria. The incidences and pathogens vary from different infection sites. Nosocomial infection still has a higher mortality rate. Once nonfermenters are detected positive, the pathogenic or colonial bacteria should be distinguished.

OBJECTIVETo determine risk factors of invasive fungal infections (IFI) in patients admitted to non-hematological oncology department and pediatric intensive care unit (PICU), in order to improve diagnostic level of invasive fungal infections.

METHODWe retrospectively assessed 85 hospitalized pediatric patients with invasive fungal infections in Beijing Children's Hospital Affiliated to Capital Medical University from Jan.2007 to Nov.2012. All the cases were either from non-hematological oncology department or the PICU.We reviewed risk factors of invasive fungal infections.

RESULTAmong 85 patients, 42 had invasive candida infection, 20 invasive aspergillus infection, 21 cryptococcus infection, 1 Histoplasma capsulatum infection and 1 Mucor mucedo infection.In the 42 patients with invasive candida infection, 5 were young infants, 3 had combined immunodeficiency, 1 cellular immunodeficiency, 25 secondary infection due to long term use of corticosteroids and/or combined use of more than 2 kinds of antibiotics with primary disease, 5 prior intestinal tract surgery or chronic diarrheal disease, 1 reflux gastritis.In the 20 patients with invasive aspergillosis infection, 10 patients had chronic granulomatous disease, 5 long term use of corticosteroids ≥ 1 month, 3 long term use of corticosteroids and combined use of more than 2 kinds of antibiotics, 2 had no apparent host factors.In the 21 patients with cryptococcus infection, 2 patients had used corticosteroids ≥ 1 month, 2 had immunodeficiency mainly for lack of antibodies, while others had no apparent host factors. The child with Mucor mucedo infection had diabetes mellitus. And the one with Histoplasma capsulatum infection had immunodeficiency.

CONCLUSIONHigh risk factors for IFI in patients admitted to non-hematological oncology department and PICU are primary immunodeficiency disease and long term use of corticosteroids and/or long term combined use of more than 2 kinds of antibiotics. Besides, young infant is also a high risk factor for invasive candida infection. Most of the cryptococcus infections and certain aspergillosis had no obvious host factors.

OBJECTIVE: To investigate the change of pathogen distribution and antibiotic resistance of pathogens isolated from in-patients with hospital acquired pneumonia (HAP) in the Department of Respiratory Medicine Intensive Care Unit (RICU) of Xiangya Hospital in 2005 and in 2011, and to provide reasonable anti-infectious strategy. METHODS: The positive susceptibility test of sputum (bronchial secretions) culture was done in patients with HAP in RICU of Xiangya Hospital in 2005 and in 2011, and the distribution feature and antibiotic resistance were compared. RESULTS: 1) In the two years, the main pathogen in HAP patients was Gram negative bacteria (infection rate was 68.07% and 65.21% in 2005 and in2011 respectively). The primary pathogenic bacteria were changed, and Acinetobacter baumanii became the most common Gram negative bacterium which replaced Pseudomonas aeruginosa, with infection rate 6.81% in 2005 to 40.87% in 2011. The infection rate of Pseudomonas aeruginosa reduced from 20.42% in 2005 to 15.60% in 2011. Haemophilus influenzae was rare. Staphylococcus aureus became the primary Gram positive bacteria, and its infection rate increased from 1.57% in 2005 to 4.83% in 2011, all of which were methicillin-resistant Staphylococcus aureus (MRSA). Saccharomyces albicans' positive culture rate increased significantly. 2) Compared with in 2005, the antibiotic resistance of pathogen isolated from the HAP pationts changed a lot in 2011: increased antibiotic resistance rate and decreased sensitivity to many antibiotics. Pseudomonas aeruginosa was only relatively susceptible to meropenem, cefoperazone sulbactam, ceftazidime, cefpodoxime, and andamicaxin in 2011. The resistance rate of Pseudomonas aeruginosa to levofloxacin, cyclopropane, amicacin, gentamicin, meropenem, cematrixone, and piperacilintazobactam increased obviously (P<0.05). Compared with 2005, Acinetobacter baumanii was totally susceptible to polymyxin and relatively susceptible to sulbactam, but it was almost completely resistant to Aminoglycoside antibiotics in 2011, with significant difference (P<0.01). CONCLUSION The main pathogen of HAP patients in RICU was Gram negative bacteria, with increased infection rate of Staphylococcus aureus and fungus. There is change pathogen distribution and antibiotic resistance, and the clinical initial experimental antibiotic therapy may be influenced. It is important to use antibiotics more rationally to delay the antibiotic resistance.
