OBJECTIVES Sonographic thoracic B-lines and N-terminal pro-brain-type natriuretic peptide (NT-ProBNP) have been shown to help differentiate between congestive heart failure (CHF) and chronic obstructive pulmonary disease (COPD). The authors hypothesized that ultrasound (US) could be used to predict CHF and that it would provide additional predictive(More)
BACKGROUND Sonographic B-lines, also known as lung comets, have been shown to correlate with the presence of extravascular lung water (EVLW). Absent in normal lungs, these sonographic findings become prominent as interstitia and alveoli fill with fluid. Characterization of the dynamics of B-lines, specifically their rate of disappearance as volume is(More)
Mineral-accumulating compartments in developing seeds of Arabidopsis were studied using high-pressure-frozen/freeze-substituted samples. Developing seeds store minerals in three locations: in the protein storage vacuoles of the embryo, and transiently in the endoplasmic reticulum (ER) and vacuolar compartments of the chalazal endosperm. Energy dispersive(More)
OBJECTIVES Approximately one in every four patients who present to the emergency department with sepsis progresses to septic shock within 72 hours of arrival. In this study, we describe key patient characteristics present within 4 hours of emergency department arrival that are associated with developing septic shock between 4 and 48 hours of emergency(More)
Between 1969 and 1979, 22 patients with medulloblastoma were treated by the same surgical group and radiation therapy group. The patients were divided into two groups because of the clinical availability in December 1974 of the computed tomographic (CT) scanner and of the operating microscope used in the initial surgical procedure. There were 11 patients in(More)
To explore the hypothesis that mental retardations are in part genetotrophic diseases (diseases in which the genetic pattern of the afflicted individual requires an augmented supply of one or more nutrients such that when these nutrients are adequately supplied the disease is ameliorated), we carried out a partially double-blind experiment with 16 retarded(More)
BACKGROUND The Affordable Care Act initiated several care coordination programs tailored to reduce emergency department (ED) use for Medicaid-enrolled frequent ED users. It is important to clarify from the patient's perspective why Medicaid enrollees who want to receive care coordination services to improve primary care utilization frequently use the ED. (More)
BACKGROUND While ultrasound (US) has continued to expedite diagnosis and therapy for critical care physicians inside the hospital system, the technology has been slow to diffuse into the pre-hospital system. Given the diagnostic benefits of thoracic ultrasound (TUS), we sought to evaluate image recognition skills for two important TUS applications; the(More)
BACKGROUND Medicaid enrollees are disproportionately represented among patients with frequent Emergency Department (ED) visits, yet prior studies investigating frequent ED users have focused on patients with all insurance types. METHODS This was a single center, retrospective study of Medicaid-insured frequent ED users (defined as ≥4 ED visits/year not(More)
BACKGROUND Variation in hospitalization rates have been described for decades, yet little is known about variation in emergency department (ED) admission rates across clinical conditions. We sought to describe variation in ED risk-standardized admission rates (RSAR) and the consistency between condition-specific ED admission rates within hospitals. (More)
