Müller M, Raabe O, Addicks K, Wenisch S, Arnhold S.In equine medicine, stem cell therapies for orthopaedic diseases are routinely accompanied by application of NSAIDs (non-steroidal anti-inflammatory drugs). Thus, it has to be analysed how NSAIDs actually affect the growth and differentiation potential of MSCs (mesenchymal stem cells) in vitro in order to predict the influence of NSAIDs such as phenylbutazone, meloxicam, celecoxib and flunixin on MSCs after grafting in vivo. The effects of NSAIDs were evaluated regarding cell viability and proliferation. Additionally, the multilineage differentiation capacity and cell migration was analysed. N...

Fortier LA, Potter HG, Rickey EJ, Schnabel LV, Foo LF, Chong LR, Stokol T, Cheetham J, Nixon AJ.The purpose of this study was to compare the outcomes of treatment with bone marrow aspirate concentrate, a simple, one-step, autogenous, and arthroscopically applicable method, with the outcomes of microfracture with regard to the repair of full-thickness cartilage defects in an equine model. Methods: Extensive (15-mm-diameter) full-thickness cartilage defects were created on the lateral trochlear ridge of the femur in twelve horses. Bone marrow was aspirated from the sternum and centrifuged to generate the bone marrow concentrate. The defects were treated with bone marrow concentrate and mic...
Nielsen MK, Baptiste KE, Tolliver SC, Collins SS, Lyons ET.Increasing levels of anthelmintic resistance in equine nematodes have led to recommendations of more sustainable anthelmintic treatment protocols with emphasis on parasite surveillance and diagnosis, rather than prophylactic calendar-based treatments. This requires knowledge of the diagnostic test performance of techniques for counts of eggs per gram of feces (EPG) as well as methods for culturing, counting and identifying third stage (L(3)) strongyle larvae per gram of feces (LPG). For horses, such information does not exist in the published literature. The aim of this study was to examine th...
Lyons ET, Tolliver SC, Kuzmina TA, Collins SS.Critical tests were performed in 2009 and 2010 in four 2-year-old horses naturally infected with internal parasites. The horses were from a herd (Farm MC) where reduced activity of ivermectin and moxidectin on small strongyles was demonstrated previously from EPG (eggs/gram of feces) data in field tests. Also, in critical tests in horses from the same herd, ivermectin was less effective on immature small strongyles in the lumen of the large intestine than when the drug was first marketed. The main interest in the present critical tests was to determine the efficacy of moxidectin (400 μg/kg) o...
Kim I, Cohen ND, Roussel A, Wang N.Gastric emptying studies are of great interest in human and veterinary medical research to evaluate effects of medications or diets for promoting gastrointestinal motility and to examine unintended side-effects of new or existing medications, diets, or procedures. Summarizing gastric emptying data is important to allow easier comparison between treatments or groups of subjects and comparisons of results among studies. The standard method for assessing gastric emptying is by using scintigraphy and summarizing the nonlinear emptying of the radioisotope. A popular model for fitting gastric emptyi...
Samper JC, Plough T.In the last decade, there has been a significant increase in the quality and commercial use of frozen equine semen. The emergence of new reproductive technologies, coupled with the high prices for an insemination dose from some stallions, the increasing costs of import and export and the marketing policies of stallion agents or owners in the sport horse industry has stimulated the fractionation of doses for insemination. Consequently, the sperm number and the volume of an insemination dose are significantly reduced. To deliver lower doses of sperm in lower volumes compared to the standard dose...
Serra M, Papakonstantinou S, Adamcova M, O'Brien PJ.The use of cardiac troponin (cTn), the 'gold-standard' biomarker of myocardial injury in humans, is growing in veterinary medicine and in animal safety studies, although there are differences in its application in animals. In this study six new assays for the marker were assessed in 619 animals of six different species (dog, cat, horse, cattle, rat and rabbit), in clinical and drug-safety studies. Healthy animals and clinical cases without cardiac disease served as controls. Several of the tested assays had poor analytic or diagnostic sensitivity and only one test was effective in all species ...
Christmann U, Hite RD, Tan RH, Thatcher CD, Witonsky SG, Werre SR, Buechner-Maxwell VA.To evaluate the phospholipid composition and function of surfactant in horses with recurrent airway obstruction (RAO) at various clinical stages and compare these properties with findings in horses without RAO. Methods: 7 horses with confirmed RAO and 7 without RAO (non-RAO horses). Methods: Pairs of RAO-affected and non-RAO horses were evaluated before, during, and after exposure to hay. Evaluations included clinical scoring, lung function testing, airway endoscopy, and bronchoalveolar lavage fluid (BALF) absolute and differential cell counts. Cell-free BALF was separated into crude surfactan...
Niedermaier G, Poth T, Gehlen H.Two warmblood horses with a history of chronic weight loss and inappetence were referred to the Faculty of Veterinary Medicine, Ludwig-Maximilians University of Munich, Germany, for further examination. The clinical signs in horse 1 were fever, tachycardia and tachypnoea, and chronic ulcerative keratopathy of both eyes. Horse 2 had severe oral ulcerations and was coughing during feeding. In both horses, increased bronchovesicular sounds were heard during auscultation of the lungs. Laboratory findings included mild anaemia, lymphopenia and hypoalbuminaemia. Radiographic examination of the thora...
Stancampiano L, Mughini Gras L, Poglayen G.The spatial distribution of large intestinal helminth parasites of 50 horses was studied. Both adult and mucosal larval stages were examined and counted within the ventral colon, dorsal colon and caecum. Thirty-three species of adult parasites were identified and their distribution in the three large intestinal regions reported, together with the localization of cyathostome encysted larvae and of empty mucosal cysts. In order to highlight interspecific interactions, both Spearman pairwise correlation (among all parasites) and multivariable negative binomial regression (among the most abundant ...
Bartholomew S, Owens SD, Ferraro GL, Carrade DD, Lara DJ, Librach FA, Borjesson DL, Galuppo LD.Stem cells derived from umbilical cord tissue (UCT) and umbilical cord blood (UCB) in human subjects and horses can be obtained in a minimally invasive fashion with successful propagation of mesenchymal stem cells (MSCs).

Methods: Twelve adult healthy horses weighing between 434 and 640 kg. Methods: Horses were sedated, placed in stocks and subjected to caudal extradural anaesthesia using lidocaine 2%. For extradural puncture an 18 gauge Tuohy needle connected to an acoustic device via an electronic pressure transducer was used. This device allowed recording of the extradural pressure profile and the transformation of pressure changes into an audible signal. Ex...
Frisbie DD, Lu Y, Kawcak CE, DiCarlo EF, Binette F, McIlwraith CW.Current autologous chondrocyte implantation (ACI) techniques require 2 surgical procedures: 1 for cell harvest and 1 for reimplantation of cultured cells. A 1-step procedure is more desirable. Objective: A 1-step surgical procedure using autologous cartilage fragments on a polydioxanone scaffold, or CAIS (cartilage autograft implantation system), in a clinically relevant defect (15-mm diameter) within equine femoral trochlea was compared with a 2-step ACI technique as well as with empty defects and defects with polydioxanone foam scaffolds alone. Methods: Controlled laboratory study. Methods: ...
Castagnetti C, Pirrone A, Mariella J, Mari G.The use of blood lactate concentration as an indicator of prognosis and disease severity has become a common practice in equine medicine, especially with the validation of handheld analyzers. However, few authors described lactate concentration in critically ill foals, and there are no published studies about the use of handheld analyzers in neonatal foals. In this study, for the first time in the equine neonate, we validated the Lactate Scout analyzer, both in healthy and in critically ill foals. The study also describes the normal range for blood lactate in 26 healthy neonatal foals during t...

Bernick A, Krohn J, Wehrend A.Patent urachus is a common disease in newborn foals. However, despite its frequency, studies investigating symptoms, comorbidities, treatment and prognosis in a large number of affected foals have rarely been conducted. This study aimed to describe the clinical symptoms, laboratory diagnostic findings and prognosis of foals with patent urachus. Data from 101 foals with a patent urachus from 2006 to 2017 were analysed. Patent urachus occurred at a frequency of 7.8% of all foals up to the 14th day of life during the study period. More colts (74.3%) than fillies (25.7%) were affected. In those wi...
Chambers A.All anti-doping programmes face financial constraints and monitoring trends in medication use or abuse in a population of racehorses can be difficult and expensive. Obtaining biological samples is the primary method of anti-doping control in individual horses or stables of horses but can be invasive and expensive. Another important practice of anti-doping control has been the confiscation of used and filled syringes by regulators for individual forensic analysis. Pooled samples testing involves the testing of multiple individual samples together as one composite sample. This pooled sample appr...
Clarysse M, Korsos S, Vlaminck L.This case report presents the removal of the left maxillary fourth premolar tooth (208) which had a chronic complicated crown root fracture in a 9-year-old Warmblood mare. Following a 14-month history of malodorous nasal discharge, clinical and radiographic examination allowed the diagnosis of a comminuted crown root fracture of 208 and oronasal fistula. Some root fragments inaccessible for oral extraction were subsequently removed using a transnasal approach through the existing oronasal fistulous tract using bronchoesophageal forceps under endoscopic guidance. The oronasal fistula was surgic...
Bardhi A, Lanci A, Mannini A, Castagnetti C, Barbarossa A.Background: Although antibiotic resistance is a well-known issue in veterinary medicine, studies proposing real-time therapeutic monitoring (TDM) are lacking. The objective of the present study was to develop a simple and rapid protocol for the real-time therapeutic monitoring of antibiotics in horses and dogs. Methods: A reliable TDM protocol should encompass guidelines for the definition of plasma/serum collection time points, sample management by the clinical staff, transportation to the laboratory, and the availability of robust and swift analytical technologies. Ampicillin and sulbactam w...

Hallman IAM, Raekallio MR, Karikoski NP.Vatinoxan is a peripherally acting alpha2-adrenoceptor antagonist used in veterinary medicine to attenuate the side effects of alpha2-adrenoceptor agonists. Vatinoxan also increases insulin response and reduces blood glucose (BG) after intravenous glucose in other species. The aim of this study was to investigate the effects of vatinoxan on BG and insulin concentration in horses after intravenous glucose. The design was an assessor-blind cross-over study. Nine horses were assigned to intravenous vatinoxan (0.2 mg/kg; VAT) or saline (SAL). Horses were administered an intravenous glucose bolus (...
Scharf A, Acutt E, Bills K, Werpy N.Deep digital flexor (DDF) tendinopathy is a significant cause of lameness and poor performance in equine athletes with substantial implications for their return to athletic performance. Magnetic resonance imaging (MRI) is increasingly integrated into the diagnostic workup of horses with foot pain and has revolutionised the diagnosis and management of these injuries. This review discusses the principles of MRI in the context of deep digital flexor tendon (DDFT) injury, comparing high-field and low-field systems and highlighting the clinical relevance of technical parameters, including field str...
Tagliavia C, Pietra M, Salamanca G, De Silva M, Canova M, Cacchione S, Castagnetti C, Bombardi C, Grandis A.Endoscopy of the guttural pouches in neonatal foals occasionally reveals atypical aspects in the course of the extracranial internal carotid arteries (ICAs) that are hardly seen in adult horses. While in veterinary medicine the data available on the presence of these anomalies in domestic mammals are limited and incomplete, in human medicine the morphological aspects of the ICAs have been the subject of extensive studies. Anomalies in the course and geometry of ICAs are commonly defined as dolichoarteriopathies, and should be classified as tortuous, kinked or coiled. To document whether the an...
Buzelato Carli I, Fielding L.Many horses receive firocoxib over multiple years, and studies evaluating hematologic and biochemical values in these animals are lacking. Objective: To describe the hematologic and biochemical values of horses receiving long-term firocoxib. Methods: A total of 79 horses receiving long-term firocoxib and 153 horses not receiving long-term firocoxib and not presenting for a specific medical problem. Methods: Retrospective study comparing horses receiving firocoxib (F group) and no firocoxib (NF group). Signalment, hematologic, and biochemical values were compared between the two groups.

Ostmeier M, Schellenberger F, Troillet A, Scharner D.Mouth specula with incisor bite plates shift the pressure from all teeth exclusively to the incisors in the opening phase which leads to increased forces on dental, osseous, and soft tissue structures of the horse's head. The potentially pathological character of these forces is described clinically by single reports of maxilla and mandible fractures occurring during the use of opened mouth specula. This study describes these forces on incisor teeth in horses during odontoplasty of cheek teeth under sedation. Measurements were documented using a modified "Günther" mouth speculum fitted with a...
Warren AS, Werner LA, Thombs LA, Rodgerson DH, Spirito MA, Sandow CB, McCracken MJ.To report the impact of ventral midline colopexy on colic, recurrence of large colon volvulus (LCV) and time to next live foal. Methods: Retrospective case control study. Methods: A total of 188 Thoroughbred broodmares surgically treated for LCV (2016-2020). Methods: Horses treated for LCV were grouped based on whether they received a colopexy (CP) or did not (NCP). All broodmares that underwent a second LCV surgery were subsequently categorized into two groups: those that received a colopexy (RCP) and those that did not (NRCP). Differences in the number of horses with large colon compromise, ...

Cantatore F, Marcatili M, Giacchi A, Stephenson R, Withers J.Morel-Lavallée lesions (MLLs) are post-traumatic, closed, degloving injuries observed in humans and cats. Morel-Lavallée lesions have never been reported in horses. An 8-year-old Warmblood gelding used for dressage presented with a large swelling on the craniomedial aspect of the stifle that did not respond to conservative treatment. Ultrasonography revealed a large anechogenic fluid-filled cavity with a well-defined capsule. Standing endoscopic examination revealed separation between the deep crural fascia, vastus medialis muscle and skin. Cytology of the fluid collected demonstrated a lymp...
Moore GE, Leatherwood JL, Glass KG, Arnold CE, Paris BL, Carter MM, George JM, Fontenot AB, Martinez RE, Franklin MA, Norton SA, Bradbery AN....The objective was to evaluate dietary fermentation product (SCFP) on joint inflammation and cartilage metabolism in exercising yearlings challenged with intra-articular lipopolysaccharide (LPS), hypothesizing dietary SCFP (TruEquineC, Diamond V Mills, Inc.) would ameliorate joint inflammation and increase cartilage metabolism. Thirty Quarter Horse yearlings were stratified by bodyweight (BW), age, sex, and randomly assigned to dietary treatments (n = 10/treatment): control (0), 46, or 92 mg/kg BW/d SCFP. Treatments were top-dressed to 1% BW/d concentrate void of added microbials. Horses ...
Berner D, Hellige M, Harvey GG, Gerlach K, Iglesias-Garcia M, Manso-Diaz G.Paranasal sinus cysts (PSC) and progressive ethmoid haematomas (PEH) are regularly observed in the paranasal sinus system. Due to their different prognosis and treatment options, differentiation of both lesions prior to surgery on computed tomographic (CT) images is important for guidance. It was hypothesised that PSC and PEH can be reliably differentiated on CT images. The database of four European equine referral centres were retrospectively searched for horses that had undergone a CT examination of the head and had a confirmed PSC or PEH. Additionally, cases with confirmed sinusitis were se...
Yuen BP, Wong KS, So YM, Kwok WH, Cheung HW, Wan TSM, Ho EN, Wong WT.The development of gene therapy techniques introduces a potential risk of gene doping, which threatens the integrity of sport. In response to this challenge, we have developed a novel analytical method that employs a multiplex polymerase chain reaction (PCR) in conjunction with liquid chromatography high-resolution tandem mass spectrometry (LC-HRMS/MS) for the simultaneous identification of multiple transgenes in equine plasma within a single reaction. The method targets three potential doping transgenes: equine growth hormone 1 (eGH1), equine growth hormone-releasing hormone (eGHRH), and equi...
Kaur K, Sharma D, Haldar KK, Kumar R.Au/ZnO nanocomposites (NCs) were synthesized and characterized by using various analytical techniques. Analysis of Au/ZnO NCs effect on H NMR, CD, fluorescence, and absorbance spectra of horse myoglobin (-Mb) at 0.0 and 5.0 M urea (pH 7.4) revealed that the Au/ZnO NCs weaken the heme-globin interactions and also disrupt the secondary/tertiary structure of -Mb. Furthermore, the Au/ZnO NCs effect of weakening the heme-globin interactions and disrupting the protein structures was detected more in the denaturant media than in the aqueous solution. Analysis of the Au/ZnO NCs effect on thermodynamic...
Toft K, Mardahl M, Hedberg-Alm Y, Anlén K, Tydén E, Nielsen MK, Honoré ML, Fromm B, Nielsen LN, Nejsum P, Thamsborg SM, Cirera S, Pihl TH.Non-strangulating intestinal infarctions (NSII) associated with Strongylus vulgaris infection and idiopathic peritonitis (IP) share similar clinical presentation but require different treatment approaches. Horses with NSII need surgical intervention, while idiopathic peritonitis cases can be successfully treated with antimicrobials. A correct diagnosis is thus crucial, but because the two diseases overlap in clinicopathological features, differentiation is difficult in clinical practice. MicroRNAs (miRNAs) are non-coding RNAs that exhibit measurable changes in abundance in tissues and circulat...

Mendes RP, Lima AE, da Cunha R, Bittar MJ, Vasconcelos CC, Piñeros DDV, Corrêa RR.Radiographic examination of the skull is a well-established and indispensable procedure for the diagnostic evaluation of dental and paranasal sinus disorders in horses. Complementary projections make significant contributions to radiographic diagnosis in nasal conchae disorders. This article describes a complementary radiographic projection designed for the evaluation of the conchal sinuses and bullae in horses. Six equine cadaveric heads were used. Specimens were dissected, and openings were created in the ventral and dorsal nasal conchae for the introduction of radiopaque material. The new r...
Kodama S, Maeda T, Mita H, Tamura N, Chiba K, Matsukawa M.Despite the prevalence of lower limb disease in racehorses, outdoor bone evaluation equipment is lacking. Consequently, a secure and cost-effective field screening system for bones is required to identify early-stage leg illness. Elastic stiffness cannot be measured using x-ray techniques and is closely associated with bone quality, which is recognized as a significant determinant of fracture risk. Quantitative ultrasound has garnered attention as a viable option, offering insights into elastic stiffness. Understanding the characteristic behaviors of ultrasonic wave properties (velocity, atten...
Taylor WTT.Many of the most important equine health problems - and their solutions - relate to the role of horses as a domestic animal, especially in riding and other kinds of transport. Recently, new discoveries from the archaeological sciences have rewritten our understanding of early horse domestication, suggesting that the first ancestors of domestic horses emerged in the Black Sea Steppes of western Eurasia at the turn of the second millennium BCE. This new chronology places horse domestication within a wider trajectory of early animal transport, including cattle and donkey, across western Asia and ...
Pinn-Woodcock TL, Aprea MS, Lejeune M, Tomlinson JE.A common diagnostic approach for febrile horses is to test for a panel of potential pathogens. Panels are curated by expert opinion and vary between diagnostic laboratories. Objective: To report the results of a newly developed equine fever diagnostic panel (EFDP) between 2019 and 2023 and evaluate the frequency of positive results. Methods: Retrospective descriptive study. Methods: The EFDP requires submission of whole blood, nasal swab, and faecal samples, and includes PCR tests for 12 pathogens that can present as fever without localising signs of illness or infection. Submission metadata a...
Wells A, Hiney K, Brady CM, Anderson KA.The welfare of horses depends on the ability of their caretakers to accurately recognize and interpret their affective states.
