Telangiectatic osteosarcoma in four dogs: Cytologic, histopathologic, cytochemical, and immunohistochemical findings.

Telangiectatic osteosarcoma is a rare variant of osteosarcoma histologically and clinically similar to hemangiosarcoma (HSA). This case series describes the imaging and cytologic features of four histologically confirmed telangiectatic osteosarcomas, including the use of cytochemical stains. Alkaline phosphatase (ALP) was applied to Wright-Giemsa-stained cytology slides, and Factor VIII immunohistochemistry was evaluated.

Safety of TCMCB07, a melanocortin-4 antagonist peptide, in dogs with naturally occurring cachexia.

Background: The melanocortin 4 antagonist TCMCB07 is safe and effective in reversing cachexia caused by sepsis or cancer in rodents. The safety and pharmacokinetics of TCMCB07 are demonstrated in healthy beagle dogs.

Hypothesis/objectives: The objectives of this study were to investigate the safety, peak plasma concentrations, and potential for efficacy of TCMCB07 in pet dogs with naturally occurring cachexia over a 4-week time period.

Development of a Formative Assessment Rubric for Peer Evaluation of Teaching (FARPET) and Pilot Use in Veterinary Online Teaching.

Peer evaluation of teaching (PET) serves an important role as a component of faculty development in the medical education field. With the emergence of COVID-19, the authors recognized the need for a flexible tool that could be used for a variety of lecture formats, including virtual instruction, and that could provide a framework for consistent and meaningful PET feedback. This teaching tip describes the creation and pilot use of a PET rubric, which includes six fixed core items (lesson structure, content organization, audiovisual facilitation, concept development, enthusiasm, and relevance) and items to be assessed separately for asynchronous lectures (cognitive engagement-asynchronous) and synchronous lectures (cognitive engagement-synchronous, discourse quality, collaborative learning, and check for understanding).

Ultrasound characteristics of feline urinary bladder transitional cell carcinoma are similar to canine urinary bladder transitional cell carcinoma.

Feline transitional cell carcinoma (TCC) is a rare neoplasia of cats with an estimated prevalence of 0.18%. Cats with TCC share clinical signs with common pathologies like feline idiopathic cystitis or urinary tract infections.
