This study compared a hospital-based aeromedical program to a ground paramedic service in order to determine whether the element of prehospital time or prehospital care is the major contributor towards improved survival. One hundred twenty-six severe blunt trauma patients were studied. There were 93(73.81%) transported by air and 33(26.19%) transported by(More)
This white paper describes a new problem, which is to determine a set of topics or subjects automatically from a corpus. The result is a large number of topics, each with meaningful names. Each of the documents in the training corpus is assigned several of these topics. Finally, using the topic classification algorithms we have previously developed in(More)
Average annual fluxes of mass, particulate organic carbon (POC), d 13 C org , particulate organic nitrogen (PON), d 15 N-PON, biogenic silica (bSiO 2), calcium carbonate (CaCO 3), and detrital material (non-biogenic) were coupled with climate records and used to examine sedimentation patterns, vertical flux variability, and organic matter sources to this(More)
The Very High Efficiency Solar Cell (VHESC) program is developing integrated optical system PV modules for portable applications that operate at greater than 50 percent efficiency. We are integrating the optical design with the solar cell design, and have entered previously unoccupied design space. Our approach is driven by proven quantitative models for(More)
We developed a prospective study to evaluate the clinician's ability to predict and diagnose cervical spine injury. Of 233 patients evaluated, 24 (10.4%) sustained cervical spine injury confirmed by radiography. The physician was able to predict injury with only 50% accuracy. The incidence of injury was 10.3% (24 of 233). Twenty percent (5 of 24) of(More)
To develop a cell-based live attenuated influenza vaccine (LAIV) manufacturing process, several different cell lines were evaluated by comparing the titer of viruses after infection with LAIV strains. While several cell lines have been reported to support influenza virus replication, the degree of replication and the ability to support replication of LAIV(More)
The purpose of this paper is to identify factors associated with improved utilization of health care resources in the treatment of patients with injury. A prospective cohort study was conducted of all trauma patients admitted to a trauma center from April 15, 1987 to February 28, 1988. Altogether, 877 patients were entered into the study: 673 (76.7%) scene(More)
A randomized, controlled trial was conducted to assess the effects of a financial and office systems intervention to increase preventive care in physicians' offices for patients aged 65 years or older. A total of 1,914 patients from 10 primary-care medical practices in central North Carolina were randomized within practices to an intervention and a(More)
STUDY OBJECTIVES To determine the utility of serum glutamic oxaloacetic transaminase (SGOT) and serum glutamic pyruvic transaminase (SGPT) in predicting intra-abdominal injury in blunt trauma patients. DESIGN Descriptive review of 309 blunt trauma admissions during study period. SETTING A 1,000-bed Level I trauma center in a major metropolitan area. (More)
STUDY OBJECTIVE To provide a population-based injury and cost profile for motorcycle injury in Connecticut. DESIGN Population-based retrospective epidemiologic review of Connecticut death certificates, hospital discharge data, and police accident reports. RESULTS Connecticut death certificates identified 112 deaths from motorcycle injuries for an annual(More)
