Association between insurance status and in-hospital outcomes in patients with out-of-hospital ventricular fibrillation arrest.

Background: Lack of health insurance is associated with adverse clinical outcomes; however, the association between health insurance status and in-hospital outcomes after out-of-hospital ventricular fibrillation (OHVFA) arrest is unclear.

Hypothesis: Lack of health insurance is associated with worse in-hospital outcomes after out-of-hospital ventricular fibrillation arrest.

Methods: From January 2003 to December 2014, hospitalizations with a primary diagnosis of OHVFA in patients ≥18 years of age were extracted from the Nationwide Inpatient Sample.

Association between distance from the radiation source and radiation exposure: A phantom-based study.

Objectives: The study evaluated the association between distance from radiation source and radiation exposure.

Background: Radiation exposure during medical procedures is associated with increased risk of cancer and other adverse effects.

Methods: An American National Standards Institute phantom was used to study the relationship between measured entrance surface exposure (MESE) and distance from the X-ray source in postero-anterior, left anterior oblique, and right anterior oblique projections.

Comparison of Diagnostic Accuracy of Digital Plethysmography Versus Duplex Ultrasound in Detecting Radial Artery Occlusion After Transradial Access.

Background: Duplex Doppler ultrasonography (USG) remains the gold standard for evaluation of radial artery occlusion (RAO) after transradial access (TRA). The diagnostic accuracy of digital plethysmography, which is cheaper and widely available, for evaluation of RAO after TRA is not known.

Methods: Patients undergoing TRA were prospectively studied.
