INTRODUCTION: Increased admissions occur in small animal veterinary emergency clinics during some holidays, and some of the increased caseload is due to ingestion of toxic substances. This report documents zinc toxicosis contributing to the death of a dog after ingestion of holiday tinsel garland. CASE STUDY: A mature boxer dog presented with a 4-day history of vomiting and diarrhea. Radiodense foreign material was detected in the stomach and removed via gastrotomy...

Positron Emission Tomography-Computed Tomography (PET-CT) is routinely used for staging and monitoring of human cancer patients and is becoming increasingly available in veterinary medicine. In this study, 18-fluorodeoxyglucose (18FDG)-PET-CT was used in dogs with naturally occurring splenic hemangiosarcoma (HSA) to assess its utility as a staging and monitoring modality as compared to standard radiography and ultrasonography. Nine dogs with stage-2 HSA underwent 18FDG-PET-CT following splenectomy and prior to commencement of chemotherapy...

Reporting of observational studies in veterinary research presents challenges that often are not addressed in published reporting guidelines. Our objective was to develop an extension of the STROBE (Strengthening the Reporting of Observational Studies in Epidemiology) statement that addresses unique reporting requirements for observational studies in veterinary medicine related to health, production, welfare, and food safety. We conducted a consensus meeting with 17 experts in Mississauga, Canada. Experts completed a premeeting survey about whether items in the STROBE statement should be modified or added to address unique issues related to observational studies in animal species with health, production, welfare, or food safety outcomes...

Synthetic estrogens and progestins are commonly used in human and veterinary medicine. After use, they reach aquatic environments via discharge of wastewaters from human and animals, thus posing potential risks to organisms. So far, very little is known about their combined effects in aquatic organisms. The aim of this study was to investigate the effects of binary mixtures of ethinylestradiol (EE2) and norgestrel (NGT) on embryonic zebrafish (Danio rerio) by measuring transcriptional alterations. Zebrafish embryos were exposed to EE2 and NGT alone or in combination at concentrations between 36 and 5513 ng L(-1) for 96 h post fertilization (hpf)...

Study combines data about the exposure of honeybees to pesticides from plant protection products and veterinary medicinal products. Residues of 200 pesticide and pesticide metabolites in 343 live and 74 poisoned honeybee samples, obtained during the years of 2014-2015, were determined by LC-MS/MS and GC-MS/MS. In 44% of live honeybee 48 different pesticide residues were found, mainly amitraz metabolites (DMF, DMPF) and chlorpyrifos. In 98% of poisoned honeybee 57 pesticides and metabolites were detected, mainly chlorpyrifos, dimethoate and clothianidin...

Antibiotics are used widely in human and veterinary medicine and are ubiquitous in environmental matrices worldwide. The influence of the concentration of antibiotics on adsorption kinetics is still unclear. This study used sulfamethoxazole (SMX) and ofloxacin (OFL) as adsorbates to investigate the adsorption kinetics on sediment affected by varying concentrations of antibiotics adsorbable species. At the experimental pH values, the major adsorbed species of SMX and OFL on sediment were SMX(0) and OFL(+) by hydrophobic interaction and electrostatic attraction, respectively...

Metal alloys are frequently used as implant materials in veterinary medicine. Recent studies suggest that many alloys induce both local and systemic inflammatory responses. In this study, 37 rhesus macaques with long-term skull-anchored percutaneous titanium alloy implants (duration, 0 to 14 y) were evaluated for changes in their hematology, coagulation, and serum chemistry profiles. Negative controls (n = 28) did not have implants. Macaques with implants had higher plasma D-dimer and lower antithrombin III concentrations than nonimplanted animals...

INTRODUCTION: 5-Hydroxytryptophan (5-HTP) supplements are available over the counter and labeled as sleeping aids and anxiolytics for human use. 5-HTP is a serotonin precursor and overdose can lead to serotonin syndrome. CASE REPORT: A 9-month-old female Labrador retriever was evaluated after ingestion of a 5-HTP supplement. Signs of agitation developed within 1 h of ingestion, and emesis was attempted by the owner with  3% hydrogen peroxide (H2O2) orally. On presentation, the dog was obtunded, bilaterally mydriatic and salivating...

Feline injection-site sarcomas are malignant skin tumours with a high local recurrence rate, ranging from 14% to 28%. The treatment of feline injection-site sarcomas includes radical surgery, radiotherapy and/or chemotherapy. In our previous study it has been demonstrated that doxorubicin conjugated to glutathione-stabilized gold nanoparticles (Au-GSH-Dox) has higher cytotoxic effects than free doxorubicin for feline fibrosarcoma cell lines with high glycoprotein P activity (FFS1, FFS3). The aim of the present study was to assess the effectiveness of intratumoural injection of Au-GSH-Dox on the growth of tumours from the FFS1 and FFS3 cell lines on chick embryo chorioallantoic membrane...

The world buffalo population is about 168 million, and it is still growing, in India, China, Brazil, and Italy. In these countries, buffalo genetic breeding programs have been performed for many decades. The occurrence of congenital malformations has caused a slowing of the genetic progress and economic loss for the breeders, due to the death of animals, or damage to their reproductive ability or failing of milk production. Moreover, they cause animal welfare reduction because they can imply foetal dystocia and because the affected animals have a reduced fitness with little chances of survival...

An elevated risk for suicide among veterinarians has stimulated research into the mental health of the veterinary profession, and more recently attention has turned to the veterinary student population. This qualitative study sought to explore UK veterinary students' perceptions and experiences of university life, and to consider how these may affect well-being. Semi-structured interviews were conducted with 18 students from a single UK school who were purposively selected to include perspectives from male, female, graduate-entry, standard-entry (straight from high school), and widening participation students across all 5 years of the program...

Individuals with a growth mindset believe that all failures are opportunities and that their baseline intelligence and talent can be used for continuous improvement. Individuals with a fixed mindset believe that baseline intelligence and talent cannot be developed. A growth mindset is associated with greater academic success and greater resilience in the face of failure or stress. Second-year veterinary students completed three surveys to determine mindset, perceived levels of stress, and life change score...

Much has been discussed about the high prevalence of psychological distress among veterinary medical students. Studies investigating general samples of veterinary medical students indicate that, on average, depression and anxiety symptoms are present at higher rates than in comparison samples. However, little is known about veterinary medical students who seek counseling. This study intends to expand the literature on veterinary student well-being, as the first to examine a sample of veterinary medical students seeking counseling services...

Social relationships are based on our ability to put ourselves in the place of others, and from there to react appropriately and logically. This empathic ability can be extended to other species, based on the human ability to develop techniques to understand and communicate with animals. In education, the benefits of training professionals with ethical and empathic tools are known. Gender, diet, past experiences, and other factors can modify a person's levels of empathy toward humans and animals, and a relationship exists between both types of empathy...

This study examined the impact of psychological capital on depressive symptoms among Doctor of Veterinary Medicine (DVM) students (n=84) over their first two semesters of studies. Our results indicated elevated rates of depression in both the first and second semesters relative to published norms. Using the typology developed by Hafen, Reisbig, White, and Rush (2008), students were classified as either "adaptive" (i.e., improving depressive symptomatology from semester to semester) or "struggling" (i.e., worsening depressive symptomatology from semester to semester)...

In recent years, resilience has been lauded as a valuable, even necessary, facet of an effective veterinary practitioner. This study describes a mixed-methods research exploration of the impact of a self-care and mental well-being teaching intervention on the self-reported resilience of 105 first-year veterinary students enrolled at the School of Veterinary Medicine, University of Surrey, UK. Quantitative data were obtained through a questionnaire, the 10-item Connor-Davidson Resilience Scale (CD-RISC 10), which students completed before and after the teaching intervention...

Peter Winter, Andrew Rix, Andrew Grant
In 2012 the United Kingdom's General Medical Council (GMC) commissioned research to develop guidance for medical schools on how best to support students with mental illness. One of the key findings from medical student focus groups in the study was students' strong belief that medical schools excluded students on mental health grounds. Students believed mental illness was a fitness to practice matter that led to eventual dismissal, although neither personal experience nor empirical evidence supported this belief...

The current EU guidelines for the environmental risk assessment of veterinary pharmaceutical products (VMPs) in groundwater (GW) suggest an approach based on the comparison between the calculated concentration in GW (PECgw) and a threshold concentration of 0.1 μg/L. The latter is the upper limit of the concentration for pesticides in groundwater in the EU. If the calculated PECgw does not exceed the threshold, then the risk is considered acceptable. It is assumed that the concentration of 0.1 μg/L is by default safe for both humans and exposed GW organisms...
