Molecular pathology in the cancer clinic – where are we now and where are we headed?

Molecular pathology is a developing sub-microscopic discipline of pathology that studies the effects of molecular variations and mutations on disease processes. The ultimate goal of molecular pathology in cancer is to predict risk, facilitate diagnosis and improve prognostication based on a complete understanding of the biological impact of specific molecular variations, mutations and dysregulations. This knowledge will provide the basis for customised cancer treatment, so-called precision medicine. Rapid developments in genomics have placed this field at the forefront of clinical molecular pathology and there are already a number of well-established genetic tests available for clinical use including PCR of antigen receptor rearrangement and KIT mutational analysis. Moving beyond tests assessing a single gene, there are significant research efforts utilising genomics to predict cancer risk, forecast aggressive behaviour and identify druggable mutations and therapeutic biomarkers. Researchers are also investigating the use of circulating cells and nucleic acid for clinically useful low morbidity genomic assessments. If we are to realise the full potential of molecular pathology and precision medicine there are a number of challenges to overcome. These include developing our understanding of the underlying biology (in particular intra-tumoural heterogeneity), methodological standardisation of assays, provision of adequate infrastructure and production of novel therapeutics backed by high-quality clinical data supporting the precision medicine approach. The era of molecular pathology holds the potential to revolutionise veterinary cancer care, but its impact on clinical practice will depend upon the extent to which the inherent challenges can be overcome.     

30 years animal welfare legislation: where are the problems of application?

The contribution deals with legal structure, organization and problems of application of the Swiss animal welfare legislation of 1978. Besides positive effects considerable problems with the application of the legislation occurred, in particular in housing of bovines, swine and laying hens. Punishable acts of animal protection in companion and pet animals were markedly increasing in the last years, particularly in dogs. There were also loopholes in the legislation, which could be filled by the new animal welfare law of 2005 and the animal welfare ordinance of 2008 with only a few exceptions.     

Molecular epidemiology of antimicrobial resistance in veterinary medicine: where do we go?

Molecular epidemiology allows us to trace specific microorganisms and mobile genetic elements and to assess their epidemiological and evolutionary relationships. Examples of molecular epidemiology investigations in veterinary hospitals are discussed. They demonstrate the great similarities with the situation in human medicine and the potential usefulness of molecular epidemiology in our fight against antimicrobial resistance and nosocomial infections in veterinary hospitals. A broad knowledge of the diversity of antimicrobial resistance determinants in some major groups of pathogens and commensals from animals such as Enterobacteriaceae, Pasteurellaceae, enterococci and staphylococci is emerging. However, there are important gaps in this knowledge, which are discussed here. Many more molecular epidemiology studies will be necessary to understand and follow the evolution of the problem in veterinary medicine and agriculture on a global scale. To be able to build useful surveillance programs and reliable epidemiological models, and to identify critical intervention points, we need to improve our understanding of antimicrobial resistance at the animal and farm levels. Studies assessing the dynamics of bacterial populations and of resistance determinants at these levels are desperately needed. Understanding the relationships between antimicrobial resistance, colonization factors, and virulence also represents a major issue for which molecular epidemiology investigations will be needed.     

The complex role of veterinary clinical teachers: how is their role perceived and what is expected of them?

The purpose of this study was to identify personal attributes in veterinary clinical teachers that are valued most by members of their work environment (fellow faculty, clinical training scholars [CTS; residents], undergraduate students, and referring veterinary surgeons) and to determine whether the opinions of these subgroups differed. Faculty (n=50), CTS (n=35), students (n=200), and referring veterinary surgeons (n=25) were presented with a list of 15 potentially desirable attributes. Respondents were asked to rank the three most important and the three least important attributes of effective clinical teachers. Respondents were also asked to select in which of the three main activities (clinical service, teaching, or research) in which clinical teachers currently invest the most and the least effort and in which they should invest the most and the least effort. All respondent groups agreed that "competence-knowledge" was among the most desirable attributes. Faculty, undergraduate students, and referring veterinary surgeons additionally included "enthusiasm" in the top three, whereas CTS regarded "respects independence" as more important. All respondent groups consistently chose "scholarly activity" as one of the three least important characteristics. A similar number of faculty members (38%) expressed that the greatest effort should be invested in clinical service or teaching, and the greatest proportions of CTS (44%) and students (56%) felt that most emphasis should be put on teaching alone. The differences in opinion between respondent groups regarding importance of attributes and emphasis of activity indicate that what is perceived as effective performance of clinical teachers differs depending on the role of those who engage with them.
