Creation and Implementation of a Blood Smear Simulation Model.

Being able to prepare a diagnostic blood smear for evaluation is an essential skill for veterinary practitioners. While this basic technique can be demonstrated via videos or illustrations, it can only be learned through practice and with feedback. With the necessity for virtual learning experiences during the COVID-19 pandemic, a model was developed and paired with an online module to facilitate at home instruction and practice of blood smear preparation.

Transcervical Vertebral Artery Origin Endarterectomy for Vertebrobasilar Insufficiency.

Vertebral artery (VA) stenosis is a cause of vertebrobasilar insufficiency (VBI) and disabling posterior circulation stroke, accounting for up to 30% of all strokes. Although the natural history of VBI is not as well delineated as that of carotid stenosis, strokes in the basilar circulation can be more disabling than their anterior circulation counterparts. Stenosis exceeding 30% at the origin of the vertebral artery is associated with increased risk of stroke.

Correlation of cytology to histology in a case of canine granulomatous colitis in a Boxer dog.

A 2-year-old castrated male mixed breed dog presented to the North Carolina State Veterinary Teaching Hospital for chronic diarrhea with hematochezia and weight loss. Cytology performed on a rectal scraping revealed macrophages containing magenta, light pink, and variably blue granular inclusions, and phagocytosed material concerning for infectious organisms. Histopathology was consistent with granulomatous colitis and identified intra-histiocytic bacterial organisms, confirmed by fluorescent in situ hybridization (FISH)-tissue culture-confirmed Escherichia coli.

Evaluation of Retention of Veterinary Clinical Pathology Knowledge between Second-Year and Fourth-Year Clinical Pathology Courses.

There is a concern over long-term retention of knowledge in professional programs. The goal of this study was to evaluate the retention of veterinary clinical pathology knowledge between the fourth-semester and fourth-year clinical pathology courses. We hypothesize that students will forget a significant amount of content area knowledge between the fourth semester and fourth year in the Doctor of Veterinary Medicine (DVM) program.

Electronic trauma resuscitation documentation and decision support using T6 Health Systems Mobile Application: A combat trauma center pilot program.

Background: The care of trauma patients in combat operations is handwritten on a five-page flow sheet. The process requires the manual scanning and uploading of paper documents to bridge the gap between electronic and paper record management. There is an urgent operational need for an information technology solution that will enable medics to better capture patient treatment information, which will improve long-term health care without impacting short-term care responsibilities.

Dynamics of CO and HO fluxes in Johnson grass in the U.S. Southern Great Plains.

Johnson grass (Sorghum halepense (L.) Pers.) is rapidly spreading throughout the continental United States (U.

Integrating eddy fluxes and remote sensing products in a rotational grazing native tallgrass prairie pasture.

Eddy covariance (EC) systems provide integrated fluxes within their footprint areas. Spatial heterogeneity of up-scaled areas and spatio-temporal mismatches between EC footprint and remote sensing pixels jeopardize the performance of most satellite-based models. To examine the impact of spatial resolution of satellite products on up-scaling of fluxes, we compared the relationships between measured eddy fluxes and enhanced vegetation index (EVI) derived from the Moderate Resolution Imaging Spectroradiometer (MODIS) at 500 and 250 m spatial resolutions, Visible Infrared Imaging Radiometer Suite (VIIRS) at 500 m spatial resolution, and Landsat at 30 m spatial resolution but integrated at the paddock-scale.

Understanding the effects of pasture type and stocking rate on the hydrology of the Southern Great Plains.

Grassland is one of the major biomes in the United States (US) and the world. In the US, the majority of grasslands are concentrated in the Great Plains and has undergone through significant interventions or management changes over the last few decades. A key economy-driven intervention in the Southern Great Plains (SGP) include the introduction of new forage species and conversion of native grassland to introduced pasture to increase productivity and its nutritive value for improved cattle production.

Adult cardiac veno-arterial extracorporeal life support (VA-ECMO): prevention and management of acute complications.

Background: Veno-arterial extracorporeal membrane oxygenation (VA-ECMO) has been shown to be a viable and effective treatment for patients suffering from refractory cardiogenic shock (rCS), which is associated with high mortality rates. Although ECMO therapy used as short-term mechanical circulatory support (MCS) has shown tremendous growth in its application over the past decade, the complication and mortality rates remain high. This retrospective study analyzes complications associated with VA-ECMO support, evaluates the use of defined protocols at a single center, and examines factors that may contribute to patient complication and mortality.

Carbon dioxide and water vapor fluxes in winter wheat and tallgrass prairie in central Oklahoma.

Winter wheat (Triticum aestivum L.) and tallgrass prairie are common land cover types in the Southern Plains of the United States. During the last century, agricultural expansion into native grasslands was extensive, particularly managed pasture or winter wheat.

Using a Modified Bookmark Procedure to Help Identify Reasonable Consequences for Academic Integrity Violations.

It is recommended that institutions develop academic conduct policies to help preserve academic integrity, enforce compliance, and aid in legal defensibility. These policies should also articulate reasonable consequences for persons found in violation. The problem, however, is that all academic misconduct offenses are not created equal, and determining reasonable consequences for these violations can be particularly challenging due to their subjective nature.

Extreme lymphocytosis with myelomonocytic morphology in a horse with diffuse large B-cell lymphoma.

An 11-year-old, 443-kg Haflinger mare was presented to the North Carolina State University Veterinary Teaching Hospital with a 2-week history of lethargy and a 3-day duration of anorexia, pyrexia, tachycardia, and ventral edema. Severe pitting edema, peripheral lymphadenopathy, and a caudal abdominal mass were noted on physical examination. An extreme leukocytosis (154.

Prohibiting Students from Asking Questions during Exams: A Guideline for Promoting Fairness and Preserving Score Validity.

Many medical and professional programs implement policies that prohibit students from asking questions during examinations. The reasoning behind these policies remains unclear to some, as there is a lack of literature addressing this topic. The purpose of this article is to present the rationale behind such policies and to discuss why these policies may help promote fairness and preserve score validity.

Proceedings of the 2015 National Toxicology Program Satellite Symposium.

The 2015 Annual National Toxicology Program Satellite Symposium, entitled "Pathology Potpourri" was held in Minneapolis, Minnesota, at the American College of Veterinary Pathologists/American Society for Veterinary Clinical Pathology/Society of Toxicologic Pathology combined meeting. The goal of this symposium is to present and discuss diagnostic pathology challenges or nomenclature issues. Because of the combined meeting, both laboratory and domestic animal cases were presented.

Scanning technology selection impacts acceptability and usefulness of image-rich content.

Objective: Clinical and research usefulness of articles can depend on image quality. This study addressed whether scans of figures in black and white (B&W), grayscale, or color, or portable document format (PDF) to tagged image file format (TIFF) conversions as provided by interlibrary loan or document delivery were viewed as acceptable or useful by radiologists or pathologists.

Methods: Residency coordinators selected eighteen figures from studies from radiology, clinical pathology, and anatomic pathology journals.

Cyniclomyces guttulatus Infection in Dogs: 19 Cases (2006-2013).

Cyniclomyces guttulatus, a gastrointestinal yeast of rabbits, is considered an uncommon, nonpathogenic, "pass through" organism and possible opportunistic pathogen in dogs that consume rabbit feces. This retrospective study aimed to characterize the presenting complaint, clinical findings, location of organisms, and final diagnosis of dogs in which yeast morphologically consistent with C. guttulatus were identified at a veterinary teaching hospital from 2006-2013.

Angiopoietin-1 inhibits toll-like receptor 4 signalling in cultured endothelial cells: role of miR-146b-5p.

Aims: Bacterial lipopolysaccharides (LPS) induce innate immune inflammatory responses in endothelial cells by activating toll-like receptor 4 (TLR4) signalling. Here, we investigate the effects of angiopoietin-1 (Ang-1) on LPS-induced TLR4 signalling and the role of the miR-146 family of micro RNAs in the effects of Ang-1 on TRL4 signalling.
