The animal was presented to the Veterinary Hospital of the Federal University of Viçosa (UFV) with a history of lameness in both pelvic limbs. Radiographic examination confirmed tarsal osteoarthritis in both tarsi, with more pronounced changes in the left tarsus. Surgical intervention was performed on the left tarsus, combining talocalcaneal arthrodesis with surgical drilling of the distal intertarsal and tarsometatarsal joints. The horse was discharged seven days postoperatively, with rest recommended until reevaluation. Six months after surgery, the horse participated in a trail ride, and on the following day, swelling of the left tarsus and marked lameness of the left hind limb were observed. The horse was referred back to the UFV Veterinary Hospital, where diagnostic imaging confirmed an incomplete sagittal fracture of the central tarsal bone and the talus. This case demonstrates that talocalcaneal arthrodesis combined with surgical drilling of the distal intertarsal and tarsometatarsal joints is a viable procedure in horses. However, complications may arise, particularly in premature return to athletic activity.

Bordini, C.g.g. ; Brandão, M.d.m. ; Flaiban, K.k.m.c. ; ABSTRACT To analyze the effects of variables on venous blood specimens from dogs intended for blood gas analysis, four samples were collected from the jugular veins of 30 animals. Two were obtained using a commercial 3mL BD syringe containing lithium heparin (LH) and a 25x7 needle, and two using a conventional 3mL syringe prepared with sodium heparin (HS) and the same needle. Air bubbles were removed, and the samples were sealed. After the initial analysis (within 20 minutes - T0), one LH sample was stored in ice water (0-4 °C) and the other refrigerated; the same procedure was applied to the HS samples. Subsequent analyses were performed at 30, 120, 240, and 360 minutes after the initial test. Time influenced the values of most variables, except chloride, causing changes in bicarbonate and base excess levels. Therefore, immediate analysis is recommended. When it is not possible, storage in ice water is preferable to refrigeration. The use of HS led to variations in ionized potassium and calcium concentrations, which should be considered by the clinician. The commercial syringe resulted in fewer variations and is therefore recommended for preferred use.

Saylak, N. ; Çatalkaya, E. ; Ersöz-Kanay, B. ; Yayla, S. ; ABSTRACT This study compared short- and long-term clinical, radiographic, and owner-reported outcomes of intramedullary cross-pinning (CRP) and locked anatomical condylar/J-shaped plates (SCP) in adult cats with distal diaphyseal and supracondylar femoral fractures. Fifty cats were randomized into two groups (n=25 each). Postoperative evaluations on day 0, weeks 4-6, and month 3 assessed reduction, joint congruity, callus formation, and healing. At 12 months, owners were surveyed. CRP showed faster callus and radiographic healing, while SCP provided better anatomical stabilization and higher owner satisfaction. Pin migration was the most common CRP complication; screw loosening was seen with SCP. Limb shortening was more frequent in CRP but clinically tolerated. The findings highlight the importance of choosing implants not only by fracture type but also considering patient temperament and postoperative care for optimal outcomes.

Arsenoaia, V.n. ; Malancus, R.n. ; ABSTRACT Pre-slaughter stress is a significant factor affecting meat quality in pigs. This study aims to investigate the impact of pre-slaughter stress on various physiological biomarkers. Pigs were subjected to a series of stressful events, including handling, transportation, and lairage, and blood samples were collected at different stages to measure cortisol, glucose, lactic acid, and eosinophil levels. Results showed that pre-slaughter stress significantly increased cortisol, glucose, and lactic acid levels, while reducing eosinophil counts, highlighting a very significant statistical correlation between stress intensity and lactic acid accumulation due to increased physical exertion and anaerobic metabolism.

This study evaluated the in vitro bioinsecticidal potential of hydroalcoholic extracts from Caesalpinia ferrea and Lippia origanoides against adult B. caprae. The extracts of C. ferrea and L. origanoides were obtained from the fruits and leaves, respectively. Specimens of B. caprae (80 per group) were exposed to five different concentrations of each extract. The tests were conducted in duplicate, using distilled water (negative control) and deltamethrin (positive control) as control groups. Mortality was assessed at 2h, 4h, 6h, 12h, 24h, and 48h after exposure to the products. Both extracts caused mortality in the lice. Total mortality was observed after 6h of exposure to L. origanoides extract at 130 mg/mL. C. ferrea presented an LC50 of 67.82mg/mL up to 4h and caused total mortality at a concentration of 78.75 mg/mL from 12h after exposure to the hydroalcoholic extracts. Due to the insecticidal activity observed, both extracts are considered promising for the control of this ectoparasite.

This toxin interferes with the transmission of nerve impulses, resulting in progressive muscle rigidity, spasms and motor difficulties. Although tetanus is uncommon in cats, when it does occur, it usually manifests as a localized form of the disease. The case report presents a 13-year old male cat with severe neurological clinical signs, including spastic tetraplegia and cranial nerve involvement. After extensive diagnostic investigation, including magnetic resonance imaging and cerebrospinal fluid analysis, other potential causes were ruled out, and the diagnosis of tetanus was established by exclusion. Treatment involved antibiotic therapy, symptomatic support and gradual withdrawal of phenobarbital, which resulted in the patient's complete recovery after two months of follow-up. The report highlights the importance of clinical diagnosis with differential screening of motor neuropathies in cats.
