Associations between day 8 oral glucose test insulin parameters (baseline [T0insulin], maximal [Cmaxinsulin], and area under the curve [AUCinsulin]) and day 1 serum markers (insulin, glucose, adiponectin, leptin, and their ratios) were examined using Spearman correlation, log-linked generalized linear models. Relative risk of exceed...
Horsepower: equine-assisted interventions are associated with reduced PTSD symptoms, improved sleep quality, and quality of life in military veterans with treatment-resistant PTSD. Military veterans are at an elevated risk of developing posttraumatic stress disorder (PTSD), while first-line trauma-focused treatments are less effective in this population. This highlights the need for novel, evidence-based complementary interventions for military veterans with treatment-resistant PTSD. Although equine-assisted interventions (EAIs) are increasingly popular and appear promising, many studies suffer from methodological issues. Therefore, further research incorporating both psychometric and physiological parameters is warranted. Unassigned: Nine consecutive groups of eight vet...
Novel technique for correcting urovagina via urethral transposition in the horse. Vesicovaginal reflux is a common cause of infertility in mares. Surgical correction is commonly recommended and involves caudal relocation of the urethral orifice which forces the urine to be expelled caudally. There have been several previously described techniques. Complications associated with caudal urethral extension occur in 11-33.3% of cases. Objective: To identify a novel technique for performing caudal urethral translocation that effectively corrects vesicovaginal reflux with minimal associated complications. Methods: In vivo experiment and clinical case series. Methods: The experimen...
Evaluation of autologous fecal microbiota transplantation for restoring equine gut microbiota after antibiotic-induced dysbiosis. Microbial resilience is important to maintain a healthy gut environment in horses, especially after antibiotic administration, but the efficacies of post-antibiotic recovery strategies remain poorly characterized. We used microbial amplicon sequencing to compare spontaneous recovery, autologous fecal microbiota transplantation (FMT), and probiotic administration in 18 horses following antibiotic-induced dysbiosis. Clinically healthy horses received a combination of cephalothin and minocycline for 5 consecutive days before intervention. Fecal microbial recovery was longitudinally evaluated by u...
A non-trauma-focused equine-assisted intervention was associated with reductions in all four PTSD symptom clusters in treatment-resistant military veterans. Veterans are at greater risk of developing post-traumatic stress disorder (PTSD) and show a poorer response to first-line treatments than civilians. Although equine-assisted interventions (EAIs) represent a promising alternative for military veterans,the underlying mechanisms remain uncertain, and their effectiveness across different PTSD symptom clusters has yet to be established. This study examined the effects of a non-trauma-focused EAI on specific PTSD symptoms in treatment-resistant military veterans. Unassigned: Participants in the intervention were military veterans diagnosed with PTSD...

Intraocular pressure (IOP) was measured from the left eye while tear production (Schirmer tear test -1; ...
Viral Hepatitis. Since 2012, 2 viral causes of hepatitis have been identified in horses. Much remains to be discovered about their transmission, risk factors for clinical disease, diagnosis, and treatment approaches. Equine parvovirus-hepatitis has been identified as the cause of acute hepatic necrosis, previously known as Theiler's disease. Equine hepacivirus is recognized as a cause of chronic fibrosing hepatitis. Diagnosis relies on ruling out other causes of hepatitis and documenting infection by serum or liver polymerase chain reaction. There is no direct antiviral for either condition and treatments are ...
Mitigating and addressing complications in equine laparoscopy. The purpose of this article was to report a condensed overview of current strategies for mitigating and managing complications in equine laparoscopic surgery. Minimally invasive surgical techniques have become standard in equine surgery for a variety of diagnostic and therapeutic procedures, with purported advantages including reduced postoperative pain, expedited recovery, fewer incisional complications, and enhanced visual imagery for the surgeon compared to traditional open approaches. Despite these benefits, complications can arise, and the literature demonstrates variability in definition...
Case Report: Oral and topical chronic administration of THC-rich and CBD-rich cannabis oil as palliative care in a rescued horse with open wound, sarcoid and chronic pain.

Efficacy of 0.5% Tretinoin in the Treatment of Equine Aural Plaques. Equine aural plaques are a benign form of auricular papillomatosis caused by equine papillomavirus. Despite the efficacy of 5% imiquimod cream, a marked local reaction is frequently observed during therapy, often requiring sedation before application. Objective: The aim of this study was to evaluate the efficacy and potential adverse effects of 0.5% topical tretinoin in the treatment of equine aural plaques. We hypothesised that tretinoin would be effective, with fewer adverse effects compared to imiquimod. Methods: The study included 10 horses of both sexes, aged between 7 months and 15 y...
A Revised View on Equine Hypertriglyceridemia, Hyperlipidemia, and Hyperlipemia. Hypertriglyceridemia, also known as hyperlipidemia or hyperlipemia, affects equids of all breeds and ages, mostly secondary to a negative energy balance triggered by a disease process. Increased triglyceride concentrations (TG) have been described in well-eating equids with endocrinopathies, atypical myopathy, severe liver disease, and after treatment with sodium-glucose transporter 2 inhibitors. The fact that equids can have substantially increased TG without showing clinical signs prompted reevaluation of the clinical effects of hypertriglyceridemia. As long as the consequences of high TG ar...
Biliary Disorders in Horses. This review will mainly focus on the presentation, diagnosis, and treatment of cholangiohepatitis in adult horses. The condition is often accompanied by some degree of intrahepatic and/or extrahepatic biliary obstruction with "sludgy" bile or actual choleliths. In horses, these calculi are typically composed of calcium bilirubinate, rather than cholesterol. There is a propensity for cholangiohepatitis to become a recurrent, chronic condition and patient management should reflect this. Although much rarer, foreign body obstruction, neoplasia and, in some parts of the world, liver flukes can als...
Effect of N-acetyl cysteine treatment on uterine cytokine and chemokine profiles in mares with persistent breeding-induced endometritis. Persistent breeding-induced endometritis (PBIE) is a major cause of infertility in mares.

Concurrently, pain-related behaviors, joint swelling, levels of inflammatory cytokines, and markers associated with extracellular ...
Myofascial trigger points as a primary cause of equine lameness: a biomechanical, neurophysiological, and fascial review. Equine lameness diagnosis is dominated by a joint- and tendon-centric paradigm. The standard diagnostic algorithm relies on gait observation, perineural and intrasynovial anesthesia, and cross-sectional imaging. It is directed almost exclusively at skeletal and articular structures. Myofascial trigger points (MTrPs) are hypersensitive, hyperirritable loci within taut bands of skeletal muscle. They produce local and referred pain on compression or contraction. In horses, MTrPs are a clinically relevant but systematically overlooked source of primary lameness. This review synthesises evidence fr...
A 12-year review of equestrian related injuries at a major trauma centre in South Africa. Few studies on equestrian-related injuries have specifically focused on patients in South Africa. The aim of this study was to review the spectrum of injuries and of patients treated at state-funded trauma centres in South Africa. Methods: A retrospective study was conducted over a 12-year period from July 2012 to February 2025 on all patients treated for equestrian-related injuries. Results: A total of 82 patients were included (83% male, median age: 17 years, median injury severity score (ISS): 9). The most common mechanism of injury was a fall ( = 41), followed by a kick ( = 38). Two were t...
Effects of acupuncture on stride, speed, and heart rate variability in Thoroughbred racehorses. Thoroughbred racehorses are at increased risk of injury during race preparations and trials, primarily due to intensive workloads that predispose them to musculoskeletal injuries. Evaluating clinical interventions to improve health and prevent injury is essential for addressing animal welfare concerns. This study investigated the medium-term effects of acupuncture on stride, speed and cardiac autonomic regulation (assessed via heart rate variability [HRV]), in Thoroughbred flat racehorses. This prospective, randomised, parallel-group study included an intervention and a control group. Thirty T...
