Cases were patients with complicated urinary tract infection (cUTI), complicated intraabdominal (cIAI), pneumonia or bacteraemia from other sources (BSI-OS) due to CRE; control groups were patients with infection caused by carbapenem-susceptible Enterobacterales (CSE), and by non-infected patients, respectively. Matching criteria included type of infection for CSE group, ward and duration of hospital admission. Conditional logistic regression was used to identify risk factors.[Findings] Overall, 235 CRE case patients, 235 CSE controls and 705 non-infected controls were included. The CRE infections were cUTI (133, 56.7%), pneumonia (44, 18.7%), cIAI and BSI-OS (29, 12.3% each). Carbapenemase genes were found in 228 isolates: OXA-48/like, 112 (47.6%), KPC, 84 (35.7%), and metallo-β-lactamases, 44 (18.7%); 13 produced two. The risk factors for CRE infection in both type of controls were (adjusted OR for CSE controls; 95% CI; p value) previous colonisation/infection by CRE (6.94; 2.74–15.53; <0.001), urinary catheter (1.78; 1.03–3.07; 0.038) and exposure to broad spectrum antibiotics, as categorical (2.20; 1.25–3.88; 0.006) and time-dependent (1.04 per day; 1.00–1.07; 0.014); chronic renal failure (2.81; 1.40–5.64; 0.004) and admission from home (0.44; 0.23–0.85; 0.014) were significant only for CSE controls. Subgroup analyses provided similar results.[Interpretation] The main risk factors for CRE infections in hospitals with high incidence included previous colonization, urinary catheter and exposure to broad spectrum antibiotics.The study was funded by the Innovative Medicines Initiative Joint Undertaking (https://www.imi.europa.eu/) under Grant Agreement No. 115620 (COMBACTE-CARE).Peer reviewe

Safety and Effectiveness of Thrombolytic Therapy Compared with Standard Anticoagulation in Subjects with Submassive Pulmonary Embolism

Objective: Thrombolytic and anticoagulation therapy modalities are the possible treatment for submassive pulmonary embolism (PE). However, the indications are still the subject of debate. The aim of the present study was to compare the efficacies of thrombolytic and standard anticoagulation treatment modalities on mortality and also to determine the safety of thrombolytic treatment in subjects with submassive PE. Materials and Methods: Subjects with submassive PE were recruited from the intensive care unit (ICU). Demographic data, comorbidity, bedside echocardiography (ECHO) findings, treatment procedure, treatment-related side effects, and total length of stay in the hospital and ICU were collected. Control ECHO was performed 48 h after the initiation of treatment. Short-term and 1-year mortality rates were recorded. The correlation between the increased risk for major bleeding and thrombolytic treatment was assessed. Results: A total of 54 subjects were enrolled during the study period. The median age of the subjects was 66 (54-73) years. Of the 54 subjects, 18 (33.3%) underwent thrombolytic treatment, and 36 (66.7%) received standard anticoagulation therapy. Short-term and 1-year mortality rates were statistically lower in subjects who received thrombolytic therapy (p=0.02 and p=0.04, respectively). The reduction in mean pulmonary arterial pressure was significantly higher in the thrombolytic treatment group (p< 0.001). Risk for major bleeding was similar between the two. Conclusion: Thrombolytic therapy may reduce the mortality rates in subjects with submassive PE without an increase in the risk of major bleeding

Maximum Inspiratory Pressure: Can it Be A Helpful Parameter for Predicting Successful Weaning in Chronic Obstructive Pulmonary Disease Patients?

Objective: To evaluate the predictive value of maximum inspiratory pressure (MIP) besides rapid and shallow breathing index (RSBI) in the weaning of chronic obstructive pulmonary disease (COPD) patients. Material and Methods: Fifty-six COPD patients with acute exacerbation and type II respiratory failure requiring invasive mechanical ventilation for more than 24 hours were enrolled in this study. Extubation was planned if the patients tolerated pressure support mode for at least two hours and spontaneous breathing during a 30 minutes T-piece trial. Breathing frequency, exhaled tidal volume, rapid and shallow breathing index (RSBI), minute ventilation (Vmin), MIP and vital capacity measurements were recorded prior to extubation. Patients were divided into two groups according to weaning success (WS) and failure. WS was defined as 48 hours of independence from mechanical ventilation after extubation. Results: Although RSBI values between two groups were not significantly different, there were statistically significant differences between the two groups in terms of MIP (30 vs 18 cmH2O; p= 0.008) and Vmin (10.40 vs 8.25; p= 0.032). Patients with a MIP value greater than or equal to 25 cm H2O had greater WS when compared to those with values lower than 25 cm H2O. Conclusion: RSBI alone seems not reliable enough to predict weaning outcome in COPD patients with type II respiratory failure due to acute exacerbation. Supported with MIP, better results may be achieved to predict weaning outcome
