Splenic hematoma and hemoperitoneum in a Thoroughbred racehorse after racing.

Objective: To describe the clinical presentation of a Thoroughbred filly with acute hemoperitoneum from a splenic source immediately after racing.

Animal: A 3-year-old Thoroughbred filly used for racing and that had raced shortly before presentation to the hospital.

Clinical Presentation, Progression, And Procedures: On presentation, the filly was quiet, alert, and responsive with a heart rate of 76 beats/min, pale mucous membranes, and absent borborygmi.

Investigation into spinal anesthetic failure with hyperbaric bupivacaine: the role of cold exposure on bupivacaine degradation.

Purpose: Hyperbaric bupivacaine (0.75% in dextrose) is used for spinal obstetric anesthesia. Occasional clusters of anesthetic failures occur in this setting, not readily attributable to clinical factors.

Assessment of multi-trophic changes in a shallow boreal lake simultaneously exposed to climate change and aerial deposition of contaminants from the Athabasca Oil Sands Region, Canada.

The Athabasca Oil Sands Region (AOSR) has been intensely developed for industrial bitumen extraction and upgrading since the 1980s. A paucity of environmental monitoring prior to development raises questions about baseline conditions in freshwater systems in the region and ecological responses to industrial activities. Further, climatic changes prompt questions about the relative roles of climate and industry in shaping aquatic ecosystems through time.

Airline pilots' knowledge and beliefs about over-the-counter medications.

Introduction: Toxicological studies of accident pilots frequently find the presence of over-the-counter (OTC) drugs. While many of these drugs are approved for use while flying, others are not. To better understand how pilots come to use unapproved OTC drugs, this study explored psychological and behavioral factors that might influence pilots' decisions about using OTC drug products.
