The antimicrobial activity of honey against common equine wound bacterial isolates.
Delayed healing associated with distal limb wounds is a particular problem in equine clinical practice. Recent studies in human beings and other species have demonstrated the beneficial wound healing properties of honey, and medical grade honey dressings are available commercially in equine practice. Equine clinicians are reported to source other non-medical grade honeys for the same purpose. ⋯ Although Manuka has been the most studied honey to date, other sources may have valuable antimicrobial properties. Since some honeys were found to be contaminated with aerobic bacteria or fungi, non-sterile honeys may not be suitable for wound treatment. Further assessment of gamma-irradiated honeys from the best performing honeys would be useful.

Feasibility and repeatability of thermal quantitative sensory testing in normal dogs and dogs with hind limb osteoarthritis-associated pain.
The objectives of this study were to determine whether thermal quantitative sensory testing (QST) can be performed in client-owned dogs, is repeatable and whether QST differs between normal dogs and dogs with hind limb osteoarthritis (OA). This clinical, prospective, observational study used clinically normal dogs (n=23) and dogs with OA-associated hind limb pain (n=9). Thermal QST was performed in standing dogs using a high-powered light source delivered by a previously validated system. ⋯ There was no difference between limbs (P=0.744) or time periods (P=0.572), when analyzed by repeated measures analysis of variance, and no interactions between group and limb, visit and limb, or visit and group. In conclusion, thermal thresholds can be measured in client owned dogs with no prior training and are repeatable from week to week. Further data are required to determine if OA results in thermal hypoalgesia as measured at the distal hind limb and whether this is an indication of central sensitization.

Clinical Trial Observational StudyOxygenation and ventilation characteristics in obese sedated dogs before and after weight loss: a clinical trial.
This prospective clinical study examined the effect of obesity and subsequent weight loss on oxygenation and ventilation during deep sedation in pet dogs. Data from nine dogs completing a formalised weight loss programme were evaluated. Dual-energy X-ray absorptiometry (DEXA) was used to quantify body fat mass prior to and after weight loss. ⋯ On multiple linear regression analysis, all oxygen indices were negatively associated with thoracic fat percentage. In conclusion, obesity decreases oxygenation in dogs during deep sedation. Oxygenation status improves with successful weight loss, but ventilation is not influenced by obesity.

Rivaroxaban demonstrates in vitro anticoagulant effects in canine plasma.
Rivaroxaban is an oral direct factor X inhibitor used in human thrombotic disorders and its oral administration makes it an attractive potential anticoagulant for dogs. The objective of this study was to evaluate the in vitro anticoagulant effect of rivaroxaban on canine pooled platelet-poor plasma (PPP). Pooled PPP was collected from 20 healthy adult Beagle dogs. ⋯ Thrombin generation was completely suppressed by concentrations ≥0.8 mg/L. In conclusion, rivaroxaban showed an in vitro concentration-dependent anticoagulant effect on canine plasma. Thrombin generation and anti-factor Xa activity were more sensitive and accurate than PT and aPTT in detecting the anticoagulant effect of rivaroxaban.

Correlations between severity of clinical signs and histopathological changes in 60 dogs with spinal cord injury associated with acute thoracolumbar intervertebral disc disease.
The outcome of spinal surgery in dogs with absent voluntary motor function and nociception following intervertebral disc (IVD) herniation is highly variable, which likely attests to differences in the severity of spinal cord damage. This retrospective study evaluated the extent to which neurological signs correlated with histologically detected spinal cord damage in 60 dogs that were euthanased because of thoracolumbar IVD herniation. ⋯ The duration of clinical signs, Schiff-Sherrington posture, loss of reflexes and pain on spinal palpation were not significantly associated with the severity of spinal cord damage. Although clinical-pathological correlation was generally good, some clinical signs frequently thought to indicate severe cord injury did not always correlate with the degree of cord damage, suggesting functional rather than structural impairment in some cases.
