Radiographic parameters for diagnosing sand colic in horses

<p>Abstract</p> <p>Background</p> <p>Ingestion of sand can cause colic, diarrhoea and weight loss in horses, but these signs are unspecific and can have many other causes. The amount of sand that induces disease may vary between individuals. To avoid over-diagnosing, it is important to determine the amount of sand that can be found in horses without clinical signs of gastrointestinal disease. The aim of this study was to use previously suggested parameters for establishing a radiographic diagnosis of sand colic, and compare these findings between a sand colic group and a control group.</p> <p>Methods</p> <p>Abdominal radiographs were obtained in 30 horses with a complaint unrelated to the gastrointestinal tract. In addition, archived abdominal radiographs of 37 clinical cases diagnosed with sand impaction were investigated. The size of the mineral opacity indicative of sand in the abdomen was measured and graded according to a previously published protocol based on height and length. Location, homogeneity, opacity and number of sand accumulations were also recorded.</p> <p>Results</p> <p>Twenty out of 30 control horses (66%) had one or more sand accumulations. In the present study; height, length and homogeneity of the accumulations were useful parameters for establishing a diagnosis of sand colic. Radiographically defined intestinal sand accumulation grades of up to 2 was a common finding in horses with no clinical signs from the gastrointestinal tract whereas most of the clinical cases had much larger grades, indicating larger sand accumulations.</p> <p>Conclusion</p> <p>Further work to establish a reliable grading system for intestinal sand content is warranted, but a previously proposed grading system based on measurements of height and length may be an alternative for easy assessment of sand accumulations in the meantime. The present study indicates that a grade 1 – 2 sand accumulation in the intestine is a frequent finding in horses. When working up a case with clinical signs from the gastrointestinal tract, one or more accumulations of this grade should not be considered the cause until other possibilities have been ruled out.</p

City of El Campo Downtown Revitalization Plan

The Revitalization Plan for Downtown El Campo is a planning document that provides guidance for the development of Downtown El Campo. This planning document includes an overview and analysis of the existing conditions in the City of El Campo and the El Campo Downtown Revitalization Area, a design proposal with vision, goals, and objectives for enhancing Downtown El Campo and a detailed implementation chapter for successful execution of the plan.This planning document presents the revitalization plan for downtown El Campo, Texas. This document was developed by Texas Target Communities (TTC) in partnership with the City of El Campo. The City of El Campo collaborated with Texas Target Communities in fall 2016 through the summer of 2017 to create a plan for revitalization of downtown El Campo. The purpose of the collaboration was to assess current community conditions, develop goals, objectives, and implementation strategies related to future development & growth strategies, through a public participatory process, in order to help guide the future growth of the City

Comparative assessment of texture features for the identification of cancer in ultrasound images: a review

In this paper, we review the use of texture features for cancer detection in Ultrasound (US) images of breast, prostate, thyroid, ovaries and liver for Computer-Aided Diagnosis (CAD) systems. This paper shows that texture features are a valuable tool to extract diagnostically relevant information from US images. This information helps practitioners to discriminate normal from abnormal tissues. A drawback of some classes of texture features comes from their sensitivity to both changes in image resolution and grayscale levels. These limitations pose a considerable challenge to CAD systems, because the information content of a specific texture feature depends on the US imaging system and its setup. Our review shows that single classes of texture features are insufficient, if considered alone, to create robust CAD systems, which can help to solve practical problems, such as cancer screening. Therefore, we recommend that the CAD system design involves testing a wide range of texture features along with features obtained with other image processing methods. Having such a competitive testing phase helps the designer to select the best feature combination for a particular problem. This approach will lead to practical US based cancer detection systems which de- liver real benefits to patients by improving the diagnosis accuracy while reducing health care cost

Surface-wave imaging of the weakly-extended Malawi Rift from ambient-noise and teleseismic Rayleigh waves from onshore and lake-bottom seismometers

Located at the southernmost sector of the Western Branch of the East African Rift System, the Malawi Rift exemplifies an active, magma-poor, weakly extended continental rift. To investigate the controls on rifting, we image crustal and uppermost mantle structure beneath the region using ambient-noise and teleseismic Rayleigh-wave phase velocities between 9 and 100 s period. Our study includes six lake-bottom seismometers located in Lake Malawi (Nyasa), the first time seismometers have been deployed in any of the African rift lakes. Noise-levels in the lake are lower than that of shallow oceanic environments and allow successful application of compliance corrections and instrument orientation determination. Resulting phase-velocity maps reveal slow velocities primarily confined to Lake Malawi at short periods (T 25 s) a prominent low-velocity anomaly exists beneath the Rungwe Volcanic Province at the northern terminus of the rift basin. Estimates of phase-velocity sensitivity indicates these low velocities occur within the lithospheric mantle and potentially uppermost asthenosphere, suggesting that mantle processes may control the association of volcanic centers and the localization of magmatism. Beneath the main portion of the Malawi Rift, a modest reduction in velocity is also observed at periods sensitive to the crust and upper mantle, but these velocities are much higher than those observed beneath Rungwe

Contemporary Issues in Women, Gender & Sexuality Studies: Sanitary Products and Menstrual Equity

Contemporary Issues in Women, Gender & Sexuality Studies Students in Introduction to Women, Gender & Sexuality Studies Spring 2020 present collaborative posters featuring a contemporary issue related to women, gender & sexuality studies that is currently a focus of activism. Working in groups of 3-6, students researched and designed an informative poster that introduces this issue, applies threshold concepts from the course (social construction of gender, structures of privilege and oppression, intersectionality), and includes examples of activism around the issue. Each poster will be accompanied by a brief presentation. The Spring 2020 course will feature the following topics and groups: Production in the Film Industry - Cody Crisman, Jeannie Jedlicka, Trixie Schlechter, Benjamin Schultz Reproductive Rights and Abortion - Camilla Crosby, Sydney Dietrich, Makenzie Maher, Kacy Tubbs, Cecilia Peery Sex Work - Zadya Abbot, Daniel Blankenship, Tania Maslennikova, Brianna Serrett, Shelby Toms Sex Ed, Sexual Health, and Women of Color -Salena Carr, Joey Jean-Louis, Alex (AP) Peterson Sanitary Products and Menstrual Equity -Roua Klai, Kendall Holland, Sheby Specht Access to Contraception - Jordyn Horvaldt, Tariqa Joseph, Katherine Lembke, Taylor Niles, Maya Parry Female Protagonists in Film, Change and Continuity - Sarah Bechen, Marcus Destin, Ryan Shearer
