OBJECTIVE: Anticoagulation remains the standard of care for line-associated upper extremity deep venous thrombosis (UEDVT). This treatment carries the risk of hemorrhagic complications, possibly more so in surgical patients. Considering the low-risk profile of UEDVT-which is associated with fewer, less severe pulmonary emboli than lower extremity deep venous thrombosis-current UEDVT treatment guidelines may be overly aggressive. The goal of this study was to review outcomes of line-associated UEDVT in critically ill patients and to define the efficacy of current treatment protocols in pulmonary embolism (PE) prevention while avoiding hemorrhagic complications...

AIM: Critical care ultrasound (CCUS) has been used by many Intensive Care Units(ICUs) worldwide, so as to guiding the diagnosis and the treatment. However, none of the publications currently systematically describe the utilization of CCUS to analyze the characteristics of hemodynamics and lung pathology upon the new admission to ICU and its potential role in patients' prognosis prediction. In this retrospective clinical study, we have demonstrated and analyzed the characteristics of hemodynamics and lung pathology assessed by CCUS and investigated its potential to predict patient outcome...

Nucleation in food colloids has been studied in detail using ultrasound spectroscopy. Our data show that classical nucleation theory (CNT) remains a sound basis from which to understand nucleation in food colloids and analogous model systems using n-alkanes. Various interpretations and modifications of CNT are discussed with regard to their relevance to food colloids. Much of the evidence presented is based on the ultrasound velocity spectrometry measurements which has many advantages for the study of nucleating systems compared to light scattering and NMR due to its sensitivity at low solid contents and its ability to measure true solid contents in the nucleation and early crystal growth stages...
