Comparison between dermatology coursework and veterinary student experience in Indonesian and US veterinary programs.

BACKGROUND: Dermatological cases are commonly encountered worldwide. Dermatology specialists and a specific dermatology curriculum may not be available in some parts of the world. OBJECTIVES: This study's first objective was to describe the dermatology curricula at a sample of American and Indonesian veterinary schools. The second objective was to investigate veterinary students' opinions regarding their readiness and confidence in managing dermatological cases. METHODS AND MATERIALS: Two online questionnaires were designed and distributed to veterinary schools in both Indonesia and the United States. One questionnaire was designed to evaluate the details of the dermatology coursework and distributed to a conveniently selected representative faculty of each school via email. The other questionnaire, which was distributed to veterinary students through a listserv, surveyed students' opinions about their education. Data were analysed using descriptive statistics and thematic data analysis. RESULTS: In the United States, 63.7% of responding veterinary schools had a specific faculty member teaching dermatology. Dermatology coursework was mandatory in 55% and 0% of schools in the United States and Indonesia, respectively. Ten of 11 responding US schools offered dermatology rotations, yet this was only required for graduation in three schools. None of the Indonesian schools offered a dermatology rotation. Students in both countries reported that they were confident in their clinical skills regardless of the presence of a board-certified dermatology referral clinician. CONCLUSIONS AND CLINICAL RELEVANCE: Our study presents an updated insight into dermatology education in the veterinary curriculum from the perspectives of both faculty and students in the United States and Indonesia.

Uncommon dermatologic manifestation (paronychia) in a cat with diabetes mellitus.

A 3.5-year-old male intact domestic short hair cat presented for a chronic wound and crusts over the claw and claw folds over several months. The cat was diagnosed with diabetes mellitus based on the presence of persistent hyperglycemia, glucosuria, and compatible clinical signs which consist of polyuria, polydipsia, polyphagia, and weight loss. Glipizide (Glucotrol XL, Pfizer, Indonesia) 2.5 mg orally twice daily was prescribed. By the seventeenth day, the patient's claws and skin around the paw had normalized and the abnormal claw sloughed off, revealing a normal claw underneath. Blood glucose, urinalysis and serum fructosamine were also normalized by the thirtieth day. The patient underwent diabetic remission, and the skin and claw lesions have remained in remission and not recurred since the treatment of the diabetes mellitus. This is the first report of a diabetic cat with dermatologic changes to the skin and claw regions. As the diabetes mellitus went into clinical remission, so too did the dermatologic manifestations, even without any specific dermatologic treatment.

Assessing the invasive potential of different source populations of ragweed (Ambrosia artemisiifolia L.) through genomically informed species distribution modelling.

The genetic composition of founding populations is likely to play a key role in determining invasion success. Individual genotypes may differ in habitat preference and environmental tolerance, so their ability to colonize novel environments can be highly variable. Despite the importance of genetic variation on invasion success, its influence on the potential distribution of invaders is rarely investigated. Here, we integrate population genomics and ecological niche models (ENMs) into a single framework to predict the distribution of globally invasive common ragweed (Ambrosia artemisiifolia) in Australia. We identified three genetic clusters for ragweed and used these to construct cluster-specific ENMs and characterize within-species niche differentiation. The potential range of ragweed in Australia depended on the genetic composition and continent of origin of the introduced population. Invaders originating from warmer, wetter climates had a broader potential distribution than those from cooler, drier ones. By quantifying this change, we identified source populations most likely to expand the ragweed distribution. As prevention remains the most effective method of invasive species management, our work provides a valuable way of ranking the threat posed by different populations to better inform management decisions.

Forecasting trait responses in novel environments to aid seed provenancing under climate change.

Revegetation projects face the major challenge of sourcing optimal plant material. This is often done with limited information about plant performance and increasingly requires factoring resilience to climate change. Functional traits can be used as quantitative indices of plant performance and guide seed provenancing, but trait values expected under novel conditions are often unknown. To support climate-resilient provenancing efforts, we develop a trait prediction model that integrates the effect of genetic variation with fine-scale temperature variation. We train our model on multiple field plantings of Arabidopsis thaliana and predict two relevant fitness traits-days-to-bolting and fecundity-across the species' European range. Prediction accuracy was high for days-to-bolting and moderate for fecundity, with the majority of trait variation explained by temperature differences between plantings. Projection under future climate predicted a decline in fecundity, although this response was heterogeneous across the range. In response, we identified novel genotypes that could be introduced to genetically offset the fitness decay. Our study highlights the value of predictive models to aid seed provenancing and improve the success of revegetation projects.

The Use of Adaptive Learning Technology to Enhance Learning in Clinical Veterinary Dermatology.

Clinical teaching in veterinary medicine is challenging for both educators and students. There is an increasing interest in the use of technology-based techniques using adaptive learning to provide students with additional learning experiences. Few studies have evaluated the use of this technique in veterinary medical education. We hypothesized that students with access to adaptive learning modules during dermatology rotation would have significantly higher dermatology test scores compared to students who did not have access to the adaptive learning modules on the same rotation. Incoming third and fourth-year veterinary students to the dermatology rotation, who agreed to participate, were randomly assigned to treatment (provided access to 10 modules using adaptive technology during the rotation) or control group (provided no access to the modules). Study participants completed a pretest two weeks before the rotation start date and a post-test near the rotation end date and a questionnaire to assess students' learning experience using adaptive learning modules. Students in the treatment group scored significantly higher on the posttest (p = .019) compared to students in the control group, with an effect size of d = 0.83. Students in both groups scored significantly higher at post-test (p < .001; d = 1.52 treatment and p = .002; d = 0.74 control) when compared to their pretest. This study shows that the tested adaptive learning platform may be an effective method to augment clinical teaching in veterinary dermatology. This study also indicates that veterinary students perceive the use of adaptive learning technology as beneficial for their education.

A retrospective evaluation of the steroid sparing effects of oral mycophenolate mofetil (MMF) as an adjunct immunosuppressant for the treatment of canine pemphigus foliaceus.

BACKGROUND: Oral mycophenolate mofetil (MMF) currently is considered a low-risk steroid-sparing therapeutic option for the management of canine pemphigus foliaceus (PF). OBJECTIVES: This retrospective study evaluates the therapeutic outcomes of dogs with PF treated with the combination of oral MMF and glucocorticoid (GC). Clinical outcomes and adverse side effects are reported. ANIMALS: Eleven dogs diagnosed with PF. MATERIALS AND METHODS: Retrospective review of medical records from dogs presented with PF to the dermatology service of a veterinary teaching hospital between 2015 and 2020. RESULTS: Eleven dogs were identified which had received concurrent GCs and MMF. The MMF dose range was 19.8-45 mg/kg/day. Only two dogs (two of 11) treated with a mean MMF dosage of 39 mg/kg/day along with oral prednisone or dexamethasone achieved complete remission (CR). Partial remission (PR) was achieved in four of 11 dogs who received either prednisone, prednisolone or dexamethasone along with MMF (mean dosage 26 mg/kg/day). Four dogs (four of 11) showed poor response to MMF given at 28.5 mg/kg/day along with prednisone or dexamethasone. In one dog (one of 11) MMF was discontinued due to severe GI upset; transient vomiting and diarrhea was observed in four of 11 dogs. The median duration of MMF therapy in conjunction with GC for all groups was 70.5 days. Tapering of oral GCs while continuing MMF administration at the same dosage and frequency led to recurrence of lesions in all PF patients. CONCLUSION: Oral MMF combined with GC achieved CR in two of 11 PF dogs included in this study. Further research of MMF efficacy in PF may need to be performed.
