The aim of this study is to evaluate the prognostic value of initial arterial lactate level and 12-hour lactate metabolic clearance rate (MCR) in patients with acute paraquat poisoning. ⋯ The initial arterial lactate level and 12-hour lactate MCR had good predictive powers in evaluating the prognosis of patients with acute paraquat poisoning, which may prove to be simpler and more practical tools in assessing the severity of paraquat poisoning.

The cardiac dipolar field is represented by the measured 12-lead electrocardiogram (ECG) and 3-lead vectorcardiogram (VCG). The objective is to derive the 12-lead ECG and 3-lead VCG from 3 measured leads acquired from only 5 electrodes. ⋯ The 12-lead ECG and 3-lead VCG can be derived accurately from 3 measured leads with high quantitative and qualitative correlations. These derived tracings can be acquired instantaneously and displayed in real time from a cardiac rhythm monitor. This will allow for immediate, on-demand, convenient, and cost-effective acquisition and analysis of the 12-lead ECG and 3-lead VCG in areas of acute patient care.

The aim of this study was to investigate the role of serum heart-type fatty acid-binding protein (H-FABP) in the evaluation of patients with carbon monoxide (CO) poisoning. ⋯ Heart-type fatty acid-binding protein may be a promising novel biomarker in the evaluation of clinical severity and in the selection of patients for HBO therapy in acute CO poisoning.

The traditional method to identify hemorrhage after trauma has been vital signs-based. More recent attempts have used mathematical prediction models, but these are limited by the need for additional data including a Focused Assessment with Sonography for Trauma exam, or an arterial blood gas. Shock Index (SI) is the mathematical relationship of the heart rate divided by the systolic blood pressure; the cutoff of >0.9 has been associated with bleeding. ⋯ SI, at a lowered threshold of ≥0.8, can be used to identify trauma patients that will require intervention for hemostasis.

Rapid diagnosis (dx) of acutely decompensated heart failure (ADHF) may be challenging in the emergency department (ED). Point-of-care ultrasonography (US) allows rapid determination of cardiac function, intravascular volume status, and presence of pulmonary edema. We test the diagnostic test characteristics of these 3 parameters in making the dx of ADHF among acutely dyspneic patients in the ED. ⋯ In this study, US was 100% specific for the dx of ADHF.
