Utility of bedside assessment to evaluate for cervical-spine fracture post ground-level fall for patients 65 years and older.

Objectives: The effectiveness of current assessment tools for cervical fracture are mixed with respect to elderly patients. We aim to examine utility of history and physical exam to assess for cervical fracture for elderly patients suffering a ground-level fall.

Methods: Retrospective cohort from a tertiary-care ED for patients ≥65 years, including dementia, after ground-level fall.

Comparison of SIRS, qSOFA, and NEWS for the early identification of sepsis in the Emergency Department.

Objectives: The increasing use of sepsis screening in the Emergency Department (ED) and the Sepsis-3 recommendation to use the quick Sepsis-related Organ Failure Assessment (qSOFA) necessitates validation. We compared Systemic Inflammatory Response Syndrome (SIRS), qSOFA, and the National Early Warning Score (NEWS) for the identification of severe sepsis and septic shock (SS/SS) during ED triage.

Methods: This was a retrospective analysis from an urban, tertiary-care academic center that included 130,595 adult visits to the ED, excluding dispositions lacking adequate clinical evaluation (n = 14,861, 11.

State of remediation and metal toxicity in the Tri-State Mining District, USA.

Mining operations in the Tri-State Mining District of Kansas, Missouri and Oklahoma (TSMD), once one of the major lead and zinc mining areas in the world, had completely ceased by 1970. As mining companies moved out, the land was left with underground tunnels and mine shafts and the surface with abandoned tailings piles, which progressively contaminated groundwater and soil. Despite remedial actions undertaken in the 1980's, areas within the TSMD still contain Cd, Pb, and Zn concentrations exceeding safe levels.

Ecological relationship between floral thermogenesis and pollination in Nelumbo lutea (Nelumbonaceae).

Premise Of Study: Floral thermogenesis is an unusual floral trait with a well-documented physiological process, and yet, there is limited understanding of how this trait influences plant reproduction. The current study was undertaken to gain a better understanding of how floral thermogenesis in Nelumbo lutea impacts pollinator attraction and consequent plant reproduction.

Methods: We conducted field studies on floral thermogenesis and thermoregulation, flower sexual development, floral visitation patterns, breeding system, pollen transfer dynamics, and floral scent production.
