Abstract Background Peripheral parenteral nutrition (PPN) is increasingly considered as an alternative to central parenteral nutrition (CPN) given the higher cost and more frequent clinical complications associated with the latter. However, the assessment of potential risks and benefits of PPN in critically ill pediatric canine patients has not been extensively performed. In this study, we aimed to explore the effect of short-term, hypocaloric PPN on weight loss, length of hospital stay, the incidence of complications, adverse effects, and mortality in critically ill pediatric canine patients. Results Between August 2015 and August 2018, a total of 59 critically ill pediatric canine patients aged from 1 to 6 months admitted at the Veterinary Sciences Research Institute of the Autonomous University of Baja California were included in this non-randomized clinical trial. Canine pediatric patients were initially allocated to 3 groups: 11 in group 1 receiving parenteral nutrition (PN) supplementation equivalent to 40% of the resting energy requirement (RER), 12 in group 2 receiving supplementation of 50% of the RER, and 36 in group 3 receiving no PN supplementation. After establishing that there was no significant difference between 40 and 50% of PN supplementation, these groups were not separated for downstream analysis. Similar lengths of hospital stays were noted among study subjects who received PN supplementation and those who did not (4.3 ± 1.5 vs. 5.0 ± 1.5, days, p = 0.097). No metabolic-, sepsis- or phlebitis-related complications were observed in any animal in the PPN supplemented group. Higher mortality (19.4% vs. 0%, p = 0.036), and a greater percentage of weight loss (9.24% vs. 0%, p

Heart disease is a major contributor to mortality and disability on a global scale. Hence, there is a need for research to improve non-invasive diagnostic techniques. Diseases in dogs with characteristics very similar to those of human pathologies hold promise as a source of data for evaluating and developing echocardiographic techniques and devices. Methods: We conducted a structured literature search from June 2022 to January 2023 to evaluate the relevance of dogs as a translational model for echocardiographic clinical research. We searched various academic databases, including PubMed Central (PMC), Core, DIGITAL.CSIC, DOAB, DOAJ, EBSCO host, Elsevier B.V, Redib, Scopus, and Web of Science, available through the Academic Information System of the Autonomous University of Baja California. Results: Out of the 243 articles initially screened, we identified 119 relevant articles that met our inclusion criteria for further analysis. This review is an introduction to the canine model by analyzing the cardiovascular anatomical similarities between the two species, the pathophysiological overlaps in some diseases, the parallels in echocardiographic techniques in dogs compared to humans, and the suitability of dogs with a naturally occurring cardiac disease as a model for translational clinical research compared to other animal species. Conclusions: This review emphasizes the importance of canine patients as an ideal cardiac disease symmetrical clinical model since they share common heart diseases with humans. Furthermore, dogs have a shorter lifespan, leading to the relatively rapid evolution of these diseases, which makes studying these pathologies and developing echocardiographic techniques more feasible. The results strongly indicate the need for interdisciplinary collaboration and translational medical research to create innovative echocardiographic technologies and improve the connection between veterinary and human cardiac imaging research.

Distance learning is a rapidly spreading form of education worldwide and it plays a crucial role to provide access to millions of people in developing countries. However, the benefits of online learning extend far beyond and became increasingly popular also in medical schools, including veterinary medicine [1,2]. In these new teaching settings, high-quality, validated and easily accessible multimedia materials are of great importance, especially in specific fields, such as radiology, where graphic resources can greatly support learning [3].The dataset presented along with this article reviews examples of 153 canine latero-lateral thoracic radiographic medical images taken and collected at the Small Animal Veterinary Teaching Hospital, Veterinary Sciences Research Institute, Autonomous University of Baja California. serves as a basis for teaching VHS calculation. Images on this dataset contain all relevant anatomical structures in the determination of VHS, which makes them optimal images for practice in calculating VHS and teaching this procedure. The number of cardiothoracic radiographic images presented here can be a great support in learning the calculation of VHS, especially when combined with distance competency-based educators' support.Acquired heart diseases in the dog are very common, clinical evidence of degenerative valvular disease is detected in approximately 30% of dogs aged 13 years and older [4]. The prevalence of Dilated Cardiomyopathy (DCM) is remarkably high in certain breeds, approximately 25% of Irish Wolfhounds, 33% of female Doberman Pinschers, and 50% of male Doberman Pinschers are diagnosed with DCM [5]. Thoracic radiography is a key component in cardiovascular evaluation, which is used to calculate the vertebral heart score (VHS). VHS measurement has been described as one of the most objective methods for assessing cardiomegaly in dogs. VHS, in addition to thorough patient history and physical examination, can be very efficient to raise clinical suspicion of underlying heart disease. The measurement is based on cardiac height and width and is normalized to overall body size by comparison to vertebral body length. ln addition to the initial assessment of heart size, the VHS method is also useful for monitoring changes in heart size in response to treatment or to assess the progression of cardiomegaly over time in canine patients [6] Fig. 1. Importantly, considerable breed and individual variation exist with VHS and dogs can have values that fall outside of the normal range even without any cardiac disease. Thus, while the VHS method is a very informative tool, it should not be used as the only means of diagnosing cardiac disease in any given patient [7].

Stray dogs are one of the main reservoirs of intestinal parasitic infections and some have zoonotic potential. An epidemiological survey was carried out between September 2017 and May 2018 in Mexicali Valley, this area sacrifices around 92,470 head of cattle monthly, which represents 27% of the national slaughter and has 71,307 hectares for crops. In this period the Municipal Animal Control Center during their routine visits to the Mexicali Valley captured 103 dogs. All the dogs were evaluated using copromicroscopic techniques to detect intestinal parasites. The general frequency of parasitic infections was 28.15% (29/103), the most frequent parasite being Dipylidium caninum 16.50% (17/103), followed by Taenia spp. 6.79% (7/103), Taenia hydatigena 2.91% (3/103), Taenia serialis 0.97% (1/103), Taenia pisiformis (0.97%), Toxocara canis 3.88% (4/103), Toxascaris leonina 1.94% (2/103), and Cystoisospora spp. 1.94% (2/103). No significant statistical associations were found between parasitic infections and the studied variables (sex, age, and size) however; there was a significant statistical association with the capture area. Most of the parasites found in this survey have potential to affect the human population and animal production.
