Sample entropy predicts lifesaving interventions in trauma patients with normal vital signs.

Introduction: Heart rate complexity, commonly described as a "new vital sign," has shown promise in predicting injury severity, but its use in clinical practice is not yet widely adopted. We previously demonstrated the ability of this noninvasive technology to predict lifesaving interventions (LSIs) in trauma patients. This study was conducted to prospectively evaluate the utility of real-time, automated, noninvasive, instantaneous sample entropy (SampEn) analysis to predict the need for an LSI in a trauma alert population presenting with normal vital signs.

Real-time heart rate entropy predicts the need for lifesaving interventions in trauma activation patients.

Background: Heart rate complexity (HRC), commonly described as a "new vital sign," has shown promise in predicting injury severity, but its use in clinical practice has been precluded by the absence of real-time data. This study was conducted to evaluate the utility of real-time, automated, instantaneous, hand-held heart rate entropy analysis in predicting the need for lifesaving interventions (LSIs). We hypothesized that real-time HRC would predict LSIs.

Hepatitis C virus induces abnormalities in surface and intraocular pressure: a comparative study.

Objectives: Various ocular lesions are associated with hepatitis C virus (HCV). Few studies have focused on untreated patients. This study aims to describe ocular lesions in untreated HCV-infected patients without ophthalmic symptoms by means of a comprehensive ophthalmologic examination.

Using micropower impulse radar technology to screen for pneumothorax: an international bi-institutional study.

Background: Pneumothoraces (PTXs) are a common entity in thoracic trauma. Micropower impulse radar (MIR) has been able to detect PTXs in surgical patients. However, this technology has not been tested previously on trauma patients.

HOMA-AD in Assessing Insulin Resistance in Lean Noncirrhotic HCV Outpatients.

Introduction. There is an association between HCV and insulin resistance (IR), which is currently assessed by HOMA-IR. There is evidence that HOMA-adiponectin (HOMA-AD) is more accurate, but its role in HCV patients is unknown.
