Stereo viewing modulates three-dimensional shape processing during object recognition: A high-density ERP study.

The role of stereo disparity in the recognition of 3-dimensional (3D) object shape remains an unresolved issue for theoretical models of the human visual system. We examined this issue using high-density (128 channel) recordings of event-related potentials (ERPs). A recognition memory task was used in which observers were trained to recognize a subset of complex, multipart, 3D novel objects under conditions of either (bi-) monocular or stereo viewing.

Early differential sensitivity of evoked-potentials to local and global shape during the perception of three-dimensional objects.

Here we investigated the time course underlying differential processing of local and global shape information during the perception of complex three-dimensional (3D) objects. Observers made shape matching judgments about pairs of sequentially presented multi-part novel objects. Event-related potentials (ERPs) were used to measure perceptual sensitivity to 3D shape differences in terms of local part structure and global shape configuration - based on predictions derived from hierarchical structural description models of object recognition.

An Evidence-based Guideline for prehospital analgesia in trauma.

Background: The management of acute traumatic pain is a crucial component of prehospital care and yet the assessment and administration of analgesia is highly variable, frequently suboptimal, and often determined by consensus-based regional protocols.

Objective: To develop an evidence-based guideline (EBG) for the clinical management of acute traumatic pain in adults and children by advanced life support (ALS) providers in the prehospital setting. Methods.

An Evidence-based Guideline for the air medical transportation of prehospital trauma patients.

Background: Decisions about the transportation of trauma patients by helicopter are often not well informed by research assessing the risks, benefits, and costs of such transport.

Objective: The objective of this evidence-based guideline (EBG) is to recommend a strategy for the selection of prehospital trauma patients who would benefit most from aeromedical transportation.

Methods: A multidisciplinary panel was recruited consisting of experts in trauma, EBG development, and emergency medical services (EMS) outcomes research.

A national model for developing, implementing, and evaluating evidence-based guidelines for prehospital care.

In 2007, the Institute of Medicine's (IOM's) Committee on the Future of Emergency Care recommended that a multidisciplinary panel establish a model for developing evidence-based protocols for the treatment of emergency medical systems (EMS) patients. In response, the National EMS Advisory Council (NEMSAC) and the Federal Interagency Committee on EMS (FICEMS) convened a panel of multidisciplinary experts to review current strategies for developing evidence-based guidelines (EBGs) and to propose a model for developing such guidelines for the prehospital milieu. This paper describes the eight-step model endorsed by FICEMS, NEMSAC, and a panel of EMS and evidence-based medicine experts.

Quality of CPR during advanced resuscitation training.

Introduction: Previous studies have documented poor quality CPR during real life resuscitation attempts. This study investigated whether poor quality CPR during advanced life support training could be contributing to poor performance in clinical practice.

Methods: Observational study of quality of CPR during advanced life support training courses before and after the implementation of the European Resuscitation Council Guidelines 2005 into the ALS course.

Pulmonary function and sleep apnea.

The purpose of this study was to determine whether there is a relationship between pulmonary function measured during wakefulness and sleep apnea. We prospectively studied 1296 patients, who were free of any lung disease, referred to our sleep clinic for evaluation of possible sleep apnea. All patients had in-hospital nocturnal polysomnography and pulmonary function measurements, which included flow-volume curve, body plethysmography, and single-breath diffusing capacity for carbon monoxide.
