Randomized Controlled Trial of Ultrasound-guided Fluid Resuscitation of Sepsis-Induced Hypoperfusion and Septic Shock.

Introduction: The ultrasound measurement of inferior vena cava (IVC) diameter change during respiratory phase to guide fluid resuscitation in shock patients is widely performed, but the benefit on reducing the mortality of sepsis patients is questionable. The study objective was to evaluate the 30-day mortality rate of patients with sepsis-induced tissue hypoperfusion (SITH) and septic shock (SS) treated with ultrasound-guided fluid management (UGFM) using ultrasonographic change of the IVC diameter during respiration compared with those treated with the usual-care strategy.

Methods: This was a randomized controlled trial conducted in an urban, university-affiliated tertiary-care hospital.

High sensitivity Troponin-I levels in asymptomatic hemodialysis patients.

Reduction in renal clearance and removal by hemodialysis adversely affect the level and utility of high-sensitivity troponin I (hsTnI) for diagnosis of acute myocardial infarction (AMI) in hemodialysis (HD) patients. Furthermore, HD process itself might cause undesirable myocardial injury and enhance post HD hsTnI levels. This comparative cross-sectional study was conducted to compare the hsTnI levels between 100 asymptomatic HD patients and their 107 matched non-chronic kidney disease (CKD) population.

Physician professionalism: definition from a generation perspective.

Objectives: The primary objective of this study was to determine whether consensuses on the definition of emergency physician professionalism exist within and among four different generations. Our secondary objective was to describe the most important characteristic related to emergency physician professionalism that each generation values.

Methods: We performed a cross-sectional survey study, using a card-sorting technique, at the emergency departments of two university-based medical centers in the United States.
