Exploring the Benefits of Stroboscopic Technology and Guided Visualization in Teaching Suturing Techniques to Veterinary Medicine Students.

Suturing is widely regarded to be a core competency of veterinary education. With curricular requirements expanding, training interventions that improve students' suturing skills without added time would be valuable. This study evaluated the effects of stroboscopic visual resistance training, a technique using intermittent occlusion of vision, and guided visualization on suturing technique and speed.

Life, Death, and Humanity in Veterinary Medicine: Is It Time to Embrace the Humanities in Veterinary Education?

Medical humanities is a multidisciplinary, interdisciplinary field of study that has experienced explosive growth in the United States since the 1960s. Two key components of medical humanities include, first, the use of literature, poetry, and visual arts in the education of medical students, and second, the representation or examination of medical culture by scholars in the humanities, arts, and social sciences such as literary and film creators, sociologists, and anthropologists. The American Association of Medical Colleges recently reported that as of 2018, approximately 94% of medical schools had core or elective humanities offerings in their curricula.

Genetics, Evolution, and Physiology of Donkeys and Mules.

The genus Equus is made up of donkeys, horses, and zebras. Despite significant variation in chromosome number across these species, interspecies breeding results in healthy, although infertile, hybrid offspring. Most notable among these are the horse-donkey hybrids, the mule and hinny.

Ectopic Trophoblast Allografts in the Horse Resist Destruction by Secondary Immune Responses.

Invasive trophoblast from Day 34 horse conceptuses survives in extrauterine sites in allogeneic recipients that are immunologically naive to donor major histocompatibility complex class I antigens. The ectopic trophoblast retains its in utero characteristics, including similar lifespan, physiologic effect of its secreted product (equine chorionic gonadotropin) upon the recipient's ovaries, and induction of host immune responses. Immunologic memory has not been considered previously in this experimental system.

Equine allogeneic bone marrow-derived mesenchymal stromal cells elicit antibody responses in vivo.

Introduction: This study tested the hypothesis that Major Histocompatibility Complex (MHC) incompatible equine mesenchymal stromal cells (MSCs) would induce cytotoxic antibodies to donor MHC antigens in recipient horses after intradermal injection. No studies to date have explored recipient antibody responses to allogeneic donor MSC transplantation in the horse. This information is critical because the horse is a valuable species for assessing the safety and efficacy of MSC treatment prior to human clinical application.

IL-22 is expressed by the invasive trophoblast of the equine (Equus caballus) chorionic girdle.

The invasive trophoblast cells of the equine placenta migrate into the endometrium to form endometrial cups, dense accumulations of trophoblast cells that produce equine chorionic gonadotropin between days 40 and 120 of normal pregnancy. The mechanisms by which the trophoblast cells invade the endometrium while evading maternal immune destruction are poorly defined. A gene expression microarray analysis performed on placental tissues obtained at day 34 of gestation revealed a >900-fold upregulation of mRNA encoding the cytokine IL-22 in chorionic girdle relative to noninvasive chorion.

Gastric and enteric phytobezoars caused by ingestion of persimmon in equids.

CASE DESCRIPTION-13 equids (10 horses, 2 donkeys, and 1 pony) were examined for signs of colic (n = 7), weight loss (6), anorexia (3), and diarrhea (2). Ten equids were evaluated in the fall (September to November). Seven equids had a history of persimmon ingestion.

The effect of siRNA treatment on experimental equine herpesvirus type 1 (EHV-1) infection in horses.

Available vaccines fail to induce lasting and protective immunity to equine herpesvirus 1 (EHV-1) associated diseases. RNA interference is a novel approach showing promise for therapeutic use in outbreak situations. This study examined the effect of small interfering RNA (siRNA) on clinical signs as well as the presence of live virus and viral DNA in nasal secretions and peripheral blood mononuclear cells (PBMCs) in horses experimentally infected with EHV-1.

Intra-abdominal hypertension in two adult horses.

Objective: To describe the clinical and pathological findings in 2 adult horses with documented increases in intra-abdominal pressure (IAP), and to describe the direct puncture technique used to measure this pressure.

Series Summary: Two adult horses developed increases in IAP secondary to large-volume abdominal effusion. A 9-year-old Quarter Horse cross gelding was presented for evaluation of urinary and neurologic signs.

Bone marrow necrosis and myelophthisis: manifestations of T-cell lymphoma in a horse.

A 14-year-old spayed American Paint mare was evaluated for mild colic, anorexia, pyrexia, and pancytopenia. Physical examination revealed mild tachycardia, tachypnea, and pale mucous membranes. Serial laboratory analyses revealed progressive pancytopenia, hyperfibrinogenemia, and hyperglobulinemia.

Assessment of clinical characteristics, management practices, and activities of geriatric horses.

Objective: To describe the demographic and clinical characteristics, management practices, and owner perception of a population of geriatric horses, and to compare these data with findings in a group of younger horses.

Design: Original study.

Animals: 218 horses.

Demographic and clinical characteristics of geriatric horses: 467 cases (1989-1999).

Objective: To describe the demographic and clinical characteristics of a population of geriatric horses.

Design: Retrospective study.

Animals: 467 horses that were > or = 20 years of age.
