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.

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.

Malnutrition is one of the most important factors for the development of nosocomial infection (NI). We performed a study of the correlation between abnormal nutritional factors and NI risk by investigating the patients who stayed longer than 3 days in the intensive care unit (ICU) of our university hospital. The patients were classified into three groups based on serum albumin levels and total lymphocyte counts (TLC). The criteria of Group I (well nourished group) were serum albumin level of 3.5 g/dl or higher and TLC of 1, 400/mm3 or higher. The criteria of Group III (severely malnourished group) were serum albumin of less than 2.8 g/dl and TLC of less than 1, 000/mm3. The other patients were classified as Group II (moderately malnourished group). The occurrences of NI were monitored during the study period and the APACHE III Score was calculated. The probability of first NI infection in Group III was 2.4 times higher than that in Groups I and II. The mortality rate of 20.5% was more significantly correlated with APACHE III Score than nutritional status. Nineteen (53%) of the total 36 NI patients were infected within 10 days after ICU admission and they all belonged to Group III. When we compared the gap period between infections, the time to first infection was significant.

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 study the nosocomial fungal infections in the patient with severe hepatitis and analyze of risk factor.

METHODSAll 115 severe hepatitis with fungal infections inpatients was studied prospectively.

RESULTSWe identified 115 cases with fungal infections, the mean age of patients was 37.2+/-21.5 years, male: 49 cases, female 66 cases. Infection of abdominal cavity accounted for 40.9%, infectious rate in respiratory tract and digestive tract were 26.9%, 21.8%, respectively. Candida albicans accounted for 67.6%. Use of broad-spectrum antibiotic and corticosteroids, neutropenia, severity of liver disease, improper medical manipulations as significant risk factors for fungal infection. Death rate of study group and control group was 59.1%, 34.8%, respectively (x2=36.0). In multivariate analysis, neutropenia, disseminated infection and severity of liver diseases were independent prognostic factors.

CONCLUSIONIdentification of risk factors and predictors of a poor outcome in patients with severe hepatitis with fungal infections, it suggested that implications in prophylaxis of fungal infection, early diagnosis and appropriate therapy would be important for these patients.

OBJECTIVETo explore the risk factors of nosocomial infection in severe craniocerebral trauma and the way of prevention.

METHODSThe clinical data of 387 patients with severe craniocerebral trauma were reviewed.

RESULTSThe total nosocomial infection rate of this study was 22.99%. Pulmonary nosocomial infection presented most frequently. The G-bacilli were the most common infectious bacteria. The mortality rate of the infection group was 38.20%.

CONCLUSIONSComplications of nosocomial infection affect the prognosis of craniocerebral trauma patients. Nosocomial infection is related to the age of the patients, craniocerebral trauma severity, unreasonable utilization of antibiotics and invasive operations, such as tracheal cannula, mechanical ventilation, urethral catheterization and deep venous catheterization. Patients with severe craniocerebral trauma should be carefully treated and nursed to avoid nosocomial infection. In order to reduce the rate of nosocomial infection, intensive measurement should be adopted.

OBJECTIVETo study the epidemiology of Acinetobacter baumannii infection in patients with ventilator-associated pneumonia (VAP).

METHODSProspective clinical study was carried out with 176 episodes of VAP with etiologic diagnosis being followed in two groups.

RESULTSTwenty-six episodes were caused by Acinetobacter baumannii and one hundred-fifty episodes were caused by "other" organisms. Using logistic regression analysis, the risk of VAP due to Acinetobacter baumannii was found to be high in patients with head trauma [odds ratio (OR) = 4.20, 95% confidence interva (CI): 2.72 to 6.48], surgery (OR = 2.88, 95% CI: 1.78 to 4.66), acute respiratory dispnea syndrome (OR = 2.81, 95% CI: 1.19 to 6.64), and large-volume pulmonary aspiration (OR = 6.71, 95% CI: 3.91 to 11.50).

CONCLUSIONSAcinetobacter baumannii pulmonary infection in incubated patients had an epidemiological pattern that different from "other" organisms. Patients with high risk identified in our study might mark the existence of cross-infection during airway manipulation.

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.
