INTRODUCTION: The results of numerous studies carried out over the last two decades have indicated that Acinetobacter spp. represents an increasingly important cause of intrahospital infections (IHI). The aim of the study was to determine potential differences in distribution of individual risk factors between the group of patients in whom multiresistant Acinetobacter spp. was isolated and the group of patients in whom it was not. MATERIAL AND METHODS: A prospective cohort study of 64 patients hospitalized with recorded IHI at the University Hospital for Digestive Surgery, Clinical Center of Serbia in the period between January and July 2011. The subjects were divided into two groups: patients with IHI in whom multiresistant Acinetobacter spp. was isolated from the biological material samples, and those with IHI without the presence of Acinetobacter spp. RESULTS: Univariate data analysis indicated presence of statistically significant difference in distribution of certain types of surgeries (esophageal, pancreatic and hepatobiliary) among the two groups of subjects, distribution of CVC placement, application of mechanical ventilation and nasogastric tube placement, length of stay in ICU, lethal outcomes and administration of third generation cephalosporins. The results of multivariate analysis indicated that length of hospitalization in ICU (> 7 days), CVC, mechanical ventilation, esophageal, pancreatic and hepatobiliary surgeries as well as administration of third generation cephalosporins are independent risk factors for colonization and infection of patients with Acinetobacter spp. CONCLUSION: Colonized or infected patients with Acinetobacter spp. play a major role in contamination of hands of the medical staff in the course of care and treatment, while inadequate hand hygiene of the staff leads to cross transmission of the causative organism to infection-free patients. Selective antibiotic pressure, particularly administration of quinolones and broad-spectrum cephalosporins, favor onset of multiresistant species of Acinetobacter spp., and therefore appropriate prophylaxis and treatment represent basic preventive measures against the onset and spreading of the causative organisms.

Abstract Background Bloodstream infection (BSI) resulting from ESKAPEEc pathogens (Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Escherichia coli, Acinetobacter baumannii, Pseudomonas aeruginosa and Enterobacter spp) is relevant to high mortality and economic cost. Data concerning the impact of BSI due to ESKAPEEc in pediatric population was virtually scant. Our purpose was to summarize the epidemiology, risk factors and outcomes of ESKAPEEc BSI among hospitalized children. Methods Inpatients diagnosed with BSI with definite etiology between January 2016 and December 2018 were enrolled retrospectively at the West China Second University Hospital. Data were systematically reviewed on patients’ clinical characteristics and laboratory findings to ascertain independent predictors, clinical features and outcomes. Results Of the 228 patients with BSI, 174 (76.3%) were caused by ESKAPEEc (124 MDR-ESKAPEEc). Multivariate analysis demonstrated that premature and/ or low birth weight (odds ratio [OR] = 2.981, P = 0.036), previous surgery and/or trauma (OR = 5.71, P = 0.029) and source of urinary tract infection (OR = 10.60, P = 0.004) were independently associated with ESKAPEEc BSI. The independent risk factor for MRD-ESKAPEEc BSI was nosocomial infection (OR = 3.314, P = 0.037). The overall mortality rate in patients with ESKAPEEc BSI was 14.4% (25/174), and no significant difference was ascertained in mortality between MRD-ESKAPEEc and non-MRD ESKAPEEc BSI groups (13.7% vs. 11.4%, P = 0.692). In addition, previous surgery and/or trauma, thrombocytopenia, and mechanical ventilation were significant risk factors for mortality caused by ESKAPEEc BSI. Conclusions More than two-thirds of BSI among hospitalized children were caused by ESKAPEEc. Previous surgery and/or trauma, thrombocytopenia and mechanical ventilation increased the risk rate for mortality in ESKAPEEc BSI. The risk factors ascertained could assist physicians to early suspect ESKAPEEc BSI and MDR ESKAPEEc BSI.

Abstract Background Enterobacteria and multidrug-resistant non-fermenting Gram-negative bacilli present a challenge in the management of invasive infections, leading to mortality rates due to their limited therapeutic arsenal. The objective of this work was to analyze risk factors that may be associated with these infections, for a better situational mapping and assertive decision-making in a university hospital in Brazil. Methods The study was conducted between January and September 2019, with 167 patients in contact isolation at a university hospital in Brazil. Potential outcome-related variables for wide-resistance Gram-negative bacteria (BGN) infections were evaluated. Risk factors were identified from univariate statistical analysis using Fisher’s test. Results 51 (30.5%) out of 167 patients in contact isolation evolved with wide-resistance BGN infection. Risk factors in univariate analysis were age, hospital unit and previous use of invasive devices. Patients aged up to 59 years were more likely to progress to infection than those aged over 60 years (p 0.0274, OR 2.2, 95% CI 1.1-4.5). Those admitted to the oncohematology (p < 0.001, OR 32.5, Cl 9.1-116.3) and intensive care unit (p < 0.001, OR 28.0, Cl 3.5-225.9) units were more likely to develop this type of infection. The least likely were those admitted to a kidney transplant unit (p 0.0034, OR 15.33, Cl 1.8-131.0). Prior use of mechanical ventilation (p 0.0058, OR 12.2, Cl 2.0-76.1) and delayed bladder catheter (p 0.0266, OR 5.0, Cl 1.2-20.1) in patients with respiratory and urinary tract infection, respectively, were also reported as risk factors related to these infections. The gender of the patients was not significant for the study. Conclusion This study determined that variables such as age, hospitalization unit, use of mechanical ventilation and delayed bladder catheter could be considered important risk factors in triggering the infectious process by wide-resistant gram-negative bacteria. Thus, the analysis of these factors becomes a great foundation to prevent the development of multiresistant pathogens through prevention strategies, prophylaxis management and more targeted empirical therapies.

Abstract Background: Cytomegalovirus (CMV) reactivation can seriously affect the clinical prognoses of critically ill patients. However, the epidemiology and predictors of CMV in immunocompetent patients with mechanical ventilation are not very clear. Methods: A single-center, prospective observational study (conducted from June 30, 2017 to July 01, 2018) with a follow-up of 90 days (September 29, 2018) that included 71 CMV-seropositive immunocompetent patients with mechanical ventilation at a 37-bed university hospital general intensive care unit (ICU) in China. Routine detection of CMV DNAemia was performed once a week until 28 days (Day1, 7, 14, 21, 28) and serology, laboratory findings, and clinical data were obtained at admission.Results: Among 71 patients, 13 (18.3%) showed CMV reactivation within ICU 28-day admission. The median time to reactivation was 7 days. CMV reactivation was related to various factors, including body weight, body mass index (BMI), sepsis, NT-proBNP, BUN, and Hb levels (P< 0.05). In the multivariate regression model, BMI, Hb level, and sepsis were associated with CMV reactivation patients (P< 0.05). Moreover, the area under the curve (AUC) of BMI, Hb and BMI combined Hb was 0.69, 0.70, 0.76, respectively. The rate of complications, duration of mechanical ventilation, hospitalization expense, length of ICU stay, and 90-day all-cause mortality rate in patients with CMV reactivation was significantly higher than in those without CMV reactivation (P< 0.05).Conclusions: Among immunocompetent patients with mechanical ventilation, the incidence of CMV reactivation was high. CMV reactivation can lead to various adverse prognoses. BMI, Hb, and sepsis were independent risk factors for CMV reactivation. BMI and Hb may predict CMV reactivation.

IntroductionToday, the general interpretation of the etiology of various psychopathological symptoms in adolescence does not talk about causes, but the risk factors.AimWe tried to determine whether traumatic experiences among adolescents represent a risk factor for suicide.MethodsThe study was conducted at the University Department for Child and Adolescent Psychiatry, University Hospital Osijek in 2006. and 2007. years.In the study period we included 100 patients, the experimental group consisted of 50 patients who were admitted to the department for attempted suicide in the order of admission to hospital treatment, the control group consisted of 50 patients admitted to the department for other psychiatric disorders, also in the order of admission to treatment / diagnosed according to DSM IV/.ResultsAge range of 13–18 years. There was no statistically significant difference between the two groups of subjects according to age (χ2 = 5289, df = 5, p = .382) and according to sex (χ2 = .694, df = 1, p = .405). In the suicidal group 38 patients (76%) reported traumatic experiences /most in family context/ while in nonsuicidal group 27 patients (54%) what is statistical difference (χ2 = 5319, df = 1, p = .021).ConclusionIn daily psychiatric work we must focus on adolescents who have experienced traumatic experiences and is therefore extremely important in anamnesis always ask for the lived traumatic experience. Family practitioners, specialists in educational institutions, parents and adolescents themselves have a role in early recognition of these risk factors.

Abstract During pregnancy the incidence of venous thromboembolism (VTE) is approximately 6 times higher than in age-matched, non-pregnant women and venous thromboembolism remains the most common cause of maternal morbidity and mortality. Low-molecular-weight-heparins are recommended for treatment of VTE during pregnancy and for prophylaxis of VTE in pregnant women with major thromboembolic risk factors. We used tinzaparin for prophylaxis and treatment of VTE in 305 consecutive pregnant women referred to the Thrombosis Centre, Gentofte University Hospital, from 1997 to 2004. In 268 pregnancies the mothers had thrombophilia, 52 women were admitted with acute VTE and 184 had previous VTE. Other clinical risk factors included previous bad obstetric outcome, recurrent miscarriages, cardiac disorders or previous thromboembolic stroke. An individual risk assessment of each pregnant woman was performed. Very high risk females were treated with tinzaparin 90 – 100 IU/kg bid, high risk females were treated with tinzaparin 100 – 125 IU/kg daily and women with moderate risk were treated with 50 – 75 IU/kg daily. 302 of 305 pregnancies (99 %) in 263 females resulted in 310 healthy babies. 306 of 310 babies had appropriate birth weight for gestational week and all babies had normal Apgar score. Two females had miscarriages (week 10 and 20) and 1 female had an elective abortion. No females had pulmonary embolism. Deep venous thrombosis occurred in 4 of 305 pregnancies = 1,3 % (week 6, 11, 27 and one day postpartum). Wound hematoma was observed after cesarean section in two women and postpartum bleeding episodes (700 – 1500 ml) were observed in 7 women (4 had severe vaginal or cervical tearings, 2 had retained placenta and 1 had placental abruption). We found no incidence of thrombocytopenia or symptomatic osteoporosis. We find that individually dosed tinzaparin is safe and seems effective in the prevention of thromboembolic complications during pregnancy. Individual risk stratification is recommended.

Abstract Background: Preliminary reports suggest that use of antipsychotic drugs is associated with an increased risk of venous thromboembolism (VTE), but others did not confirm these results. Objective: To evaluate the relationship between antipsychotic drugs and VTE. Design: Case-control study (EDITH) designed to investigate genetic and environmental risk factors of VTE. Setting: Brest University Hospital. Participants: 857 patients consecutively hospitalized for a documented venous thromboembolic event were included between May 2000 and May 2004. Controls were matched on age, sex and the main risk factors of venous thromboembolism (cancer, surgery, pregnancy…). Results: The mean age of patients was 67.7 year. No significant difference was found between cases and controls concerning the main characteristics, except for smocking and body mass index. Among cases, 89 (10.4%) were current users of neuroleptics compared to 35 (4.8%) among controls. Current use of neuroleptics was associated with a significant increased risk of venous thromboembolism (OR = 2.32, 95% CI: 1.55–3.48). Excluding neuroleptics used for non psychiatric disorders, and after adjustment on the main confounding factors, this association remained significant (OR = 3.48, 95% CI: 2.00–6.04). No difference was found between the different chemical categories of neuroleptics, but the number of patients in some groups had limited statistical power to demonstrate significant differences. Biological mechanisms of action have been proposed to explain this relation. Analyses are ongoing for anti-phospholipid antibodies and homocysteine. Conclusion: In this case-control study of hospitalized patients, neuroleptics use was associated with a significant increased risk of venous thromboembolism. These results are concordant with previous reports. Nevertheless, further investigations are needed to explain wich mechanisms may be involved in such association and before use of neuroleptics can be definitely considered as risk factor for venous thromboembolism.

BACKGROUND: Clinical features associated with Gram-negative bacterial isolates with extended-spectrum beta-lactamase (ESBL)- and AmpC-mediated resistance identified in Canadian hospitals is largely unknown. The objective of the present study was to determine the demographics, risk factors and outcomes of patients with ESBL- or AmpC-mediated resistant organisms in Canadian hospitals.METHODS: Patients with clinical cultures ofEscherichia coliorKlebsiellaspecies were matched with patients with a similar organism but susceptible to third-generation cephalosporins. Molecular identification of the AmpC or ESBL was determined using a combination of polymerase chain reaction and sequence analysis. Univariate and multivariate logistic regression analysis was performed to identify variables associated with becoming a case.RESULTS: Eight Canadian hospitals identified 106 cases (ESBL/AmpC) and 106 controls. All risk factors identified in the univariate analysis as a predictor of being an ESBL/AmpC cases at the 0.20 P-value were included in the multivariate analysis. No significant differences in outcomes were observed (unfavourable responses 17% versus 15% and mortality rates 13% versus 7%, P not significant). Multivariate logistic regression found an association of becoming an ESBL/AmpC case with: previous admission to a nursing home (OR 8.28, P=0.01) or acute care facility (OR 1.96, P=0.03), length of stay before infection (OR 3.05, P=0.004), and previous use of first-generation cephalosporins (OR 2.38, P=0.02) or third-generation cephalosporins (OR 4.52, P=0.01). Appropriate antibiotics were more likely to be given to controls (27.0% versus 13.3%, P=0.05) and number of days to appropriate antibiotics was longer for cases (median 2.8 days versus 1.2 days, P=0.05).CONCLUSION: The importance of patient medical history, present admission and antibiotic use should be considered for allE coliorKlebsiellaspecies patients pending susceptibility testing results.

Introduction. Linear growth failure is caused by multiple factors including parental factors. Objective. The aim of this study was to evaluate parental risk factors for intrauterine growth restriction (IUGR) on a population of Romanian newborn infants in a tertiary level maternity facility for a period of 2.5 years. Methods. A retrospective matched case-control study was conducted in the Emergency County Hospital of Cluj-Napoca, a university hospital in North-Western Romania. The sample was selected from 4,790 infants admitted to the Neonatal Ward at 1st Gynecology Clinic between January 2012 and June 2014. Results. The age of mothers was significantly lower in the IUGR group compared to controls (p=0.041). A significantly higher percentage of mothers had hypertension in the IUGR group compared to those in the control group (p<0.05). No other significant differences were identified with regard to the investigated characteristics of mothers between IUGR infants compared to controls (p>0.13). The age of fathers of infants with IUGR proved significantly lower compared to controls (p=0.0278). The analysis of infants? comorbidities revealed no significant difference between groups for respiratory distress, hyperbilirubinemia, hypocalcaemia, and heart failure (p>0.27). Intracranial hemorrhage, necrotizing enterocolitis and hypoglycemia were significantly higher in the IUGR group compared to controls. The logistic regression identified hypertension as a significant risk factor for IUGR (OR=2.4, 95% CI [1.3-4.5]). Conclusion. Although the age of the mothers and fathers proved significantly lower in the IUGR group compared to controls, only hypertension in the mothers proved significant risk factors for IUGR.
