Catheter-related bloodstream infections (CRBSIs) are among the most frequent healthcare-associated infections and cause considerable morbidity, mortality, and resource use. CRBSI surveillance serves quality improvement, but is often restricted to intensive care units (ICUs). We conducted a four-month prospective cohort study of all non-cuffed central venous(More)
There are few data on indications for central venous catheter (CVC) use. We conducted an observational, hospital-wide prospective cohort study to quantify the indications for catheter placement over dwell time and to investigate agreement between healthcare workers (HCWs) on CVC use. Catheter use was observed by on-site visits, HCW interviews, and screening(More)
STUDY OBJECTIVE To evaluate the accuracy of cardiac index (CI) as measured by echo-transesophageal Doppler monitoring (echo-TDM) with CI measured by the transpulmonary thermodilution technique. DESIGN Prospective, observational study. SETTING University hospital. PATIENTS 16 patients scheduled for elective lung cancer resection. INTERVENTIONS(More)
Over the past decades, major progress in patient selection, surgical techniques and anaesthetic management have largely contributed to improved outcome in lung cancer surgery. The purpose of this study was to identify predictors of post-operative cardiopulmonary morbidity in patients with a forced expiratory volume in 1 s <80% predicted, who underwent(More)
INTRODUCTION Left ventricular (LV) dysfunction frequently occurs after cardiac surgery, requiring inotropic treatment and/or mechanical circulatory support. In this study, we aimed to identify clinical, surgical and echocardiographic factors that are associated with LV dysfunction during weaning from cardiopulmonary bypass (CPB) in high-risk patients(More)

Frost formation on an upright freezer evaporator is investigated experimentally on real refrigerator geometry. It’s effects on overall heat transfer value (UA), airside pressure drop and airflow rate is observed with respect to time. That is, the real time evaporator performance under frosted conditions is evaluated. Airflow rate is obtained with respect to(More)
BACKGROUND Ultrasound guidance for the insertion of central venous catheters (CVCs) reduces mechanical complications and shortens insertion time, but its effect on CVC-associated bloodstream infection (CABSI) remains controversial. AIM To test the effect of ultrasound-guided CVC insertion on CABSI in a hospital-wide setting. METHODS A four-year(More)

In this study, the x-ray system is used as an observation tool for refrigerant movements in a domestic refrigerator. It is intended to show researchers what is happening inside the tubes when we plug in the refrigerator. The effect of ambient temperature is included to investigate the response of the system. During the experimental studies, ambient(More)
K nearest neighbor and Bayesian algorithms are effective methods of machine learning. In this work a data elimination approach is proposed to improve data clustering. The proposed method is based on hybridization of K nearest neighbor and Bayesian learning algorithms. The suggested method is tested on well-known machine learning data sets such as iris, wine(More)
