BACKGROUND In sepsis, whether the assessment of left ventricular global longitudinal systolic strain (GLS) is feasible and prognostically relevant remains controversial. METHODS AND RESULTS Consecutive patients admitted to a high-dependency observational unit with sepsis or septic shock were evaluated. Left ventricular ejection fraction (EF) by planimetry(More)
In 210 consecutive patients undergoing emergency central venous catheterization, we studied whether an ultrasonography examination performed at the bedside by an emergency physician can be an alternative method to chest X-ray study to verify the correct central venous catheter placement, and to identify mechanical complications. A prospective, blinded,(More)
BACKGROUND Preliminary clinical and experimental results suggest that iron can modify hepatocytes' insulin sensitivity by interfering with insulin receptor and intracellular insulin signalling. AIM To evaluate in vivo the influence of iron on insulin resistance and insulin release in patients with non-alcoholic fatty liver disease and in vitro the(More)
We compared the work needed to retract a non-lubricated and a lubricated stylet from a tracheal tube over 24 h. Stylets were lubricated with sterile water, silicone fluid, lidocaine spray, lidocaine gel, MedPro(®) lubricating gel or Lacri-Lube(®). The mean (SD) work in joules needed to retract the stylet by 5 cm from the tracheal tube was recorded(More)
This is a retrospective longitudinal follow-up study of 25 HIV/HCV positive cirrhotic patients not responding to peg-IFN plus ribavirin, and 25 untreated controls matched for age (+/-5 years), gender and Child-Pugh score. The primary endpoint of the study was the incidence of cirrhosis progression (CP) defined as the occurrence of at least one of the(More)
INTRODUCTION Pulmonary embolism (PE) is a life-threatening illness with high morbidity and mortality. Echocardiography (ECG) plays an important role in the early identification of right ventricular (RV) dysfunction, making it a helpful tool in identifying hemodynamically stable patients affected by PE with a higher mortality risk. The purpose of this study(More)
The effect of acetylsalicylic acid (ASA) on platelet aggregation (PA) and thromboxane A2 (TxA2) formation was investigated in vitro and ex vivo after 1 g or 300 mg ASA administration to healthy subjects. 50-100 microM ASA inhibited PA by single aggregating agent such as platelet aggregating factor (PAF) or epinephrine and reduced to less than or equal to 5%(More)
In a group of septic patients, we assess the short-term prognostic value of LV systolic performance, evaluated through conventional left ventricular ejection fraction (LVEF) and left ventricular global longitudinal strain (LV GLS). One hundred forty-seven patients with sepsis were recruited; LVEF by planimetry and peak GLS by 2D speckle tracking could be(More)
