- Effect of owners education and vets communication on therapeutic adherence in pet practicePublication . Dinis, Jorge; Baptista, Catarina Jota; Martins, Ângela; Coelho, Ana Cláudia; Oliveira, Paula A.The success of disease treatment in veterinary medicine depends on a correct diagnosis, the choice of an appropriate therapy, and the ability of the animal's owner to administer the medication correctly. This study aims to identify and understand the factors that interfere with therapeutic adherence (TA), namely the level of education of owners and the influence of veterinary communication, based on questionnaires conducted in a small animal University Hospital in Vila Real, Portugal. “Oversight” was identified by 25% of respondents as the reason for not administering medication properly to their pets. However, when we correlated these answers with owners' characterization, we found that households made up of more than one person were less likely to forget their treatment regimen (p=0.04). Owners with higher education levels and a more transparent relationship with their veterinarians are more likely to deliver superior health care to their pets. This study suggests that veterinarians should consider these aspects when communicating with the owners to promote a better outcome for their clinical cases. The owners' perspective regarding veterinarian instructions therapy is crucial to design strategies and to improve TA in the long term.
- The first full study of heavy metal(loid)s in western-European hedgehogs (Erinaceus europaeus) from PortugalPublication . Baptista, Catarina Jota; Seixas, Fernanda; Gonzalo-Orden, José M.; Patinha, Carla; Pato, Pedro; Silva, Eduardo Ferreira da; Casero, María; Brazio, Erica; Brandão, Ricardo; Costa, Daniela; Mateus, Teresa L.; Coelho, Ana C.; Oliveira, Paula A.The western-European hedgehog (Erinaceus europaeus) is an insectivore with a wide distribution in Portugal and a potential tool for biomonitoring relevant One Health hazards, including heavy metal(loid)s’ pollution. The aim of this study was to positively contribute to the current knowledge about the metal(loid) pollution in Portugal. Forty-six hedgehogs (from rescue centres; with known provenance) were necropsied. Sex, age category and weight were determined. Spines, liver and kidney were collected, and metalloid concentrations were determined by inductively coupled plasma mass spectrophotometry (ICP-MS). In general, results did not present alarming metal(loid) concentrations, with the exception of cadmium (Cd) (in the kidneys) and copper (Cu). Hedgehogs from Viana do Castelo and Viseu showed elevated concentrations of arsenic (As) and Castelo Branco presented concerning values of cadmium (Cd). Adult and heavier hedgehogs tended to present higher levels of metal(loid)s. Sex does not seem to significantly affect the metal(loid)s’ concentrations. Further analysis would be needed to prioritize areas with detail and allow the application of the necessary mitigation strategies.
- Heavy metal and metalloid concentrations in red deer (Cervus elaphus) and their human health implications from One Health perspectivePublication . Baptista, Catarina Jota; Seixas, Fernanda; Gonzalo-Orden, José M.; Patinha, Carla; Pato, Pedro; Silva, Eduardo Ferreira da; Fernandes, Gilberto; Oliveira, Paula A.The red deer is an ungulate and large game species. The contamination of the ecosystems by metal(loid)s may lead to the exposure of animals (as well as humans) through water and food resources. The direct contact of hunters and wild animal meat consumers with deer carcasses may be a potential contaminant source. This study aimed to determine the metal(loid)s’ concentrations in the liver and kidney of red deer from two regions of Portugal (Idanha-a-Nova and Lousã), and to relate these with histopathologic lesions. Thirteen young male deer were submitted to metal(loid) determination (As, Cd, Co, Cr, Cu, Pb, and Zn) by inductively coupled plasma mass spectrophotometry (ICP-MS) and histopathology examination. Renal Cd (8.072 ± 5.766 mg/kg dw) and hepatic Pb (3.824 ± 6.098 mg/kg dw) mean values were high, considering the maximum values for consumption established by the European Commission. The hepatic mean value of Cu was significantly higher in Idanha-a-Nova (150.059 ± 33.321 mg/kg dw), and it is at the Cu toxicity limit considered for ruminants (150 mg/kg). The pollution induced by Panasqueira mines (Castelo Branco) may be a possible explanation for some of the findings, especially the higher values of hepatic Cu and Pb found in Idanha-a-Nova deer. These results have high importance under a One Health perspective, since they have implications in public health, and pose at risk the imbalance of animal populations and ecosystems.
- How to design a biomonitoring study : a practical guide for veterinary professionals under a one health approachPublication . Baptista, Catarina Jota; Seixas, Fernanda; Gonzalo-Orden, José M.; Oliveira, Paula A.Currently, veterinarians can see their daily practice and medical tasks as constant opportunities for passive surveillance of One Health threats, such as infectious zoonotic diseases and chemical pollution effects on living beings. The present study aimed to provide a practical guide to designing a biomonitoring study during veterinary clinical practice without time-consuming procedures or significant costs. The constant access to several species' specimens provides the necessary samples to perform a biomonitoring study of environmental pollutants at the regional or national level. Generally, most health professionals know what to do (or where to find information) to report a disease outbreak. However, a summarized background to perform a biomonitoring study of a chemical hazard is missing. The authors of the current study provided a flow chart with the main steps to conduct a biomonitoring study in different fields of veterinary medicine. Thus, a biomonitoring study might give veterinarians (as other health professionals) a positive contribution to the clinical cases’ resolution, while improving the general knowledge about the impact of environmental contamination on animals and human health.
- Renal biomarkers in companion animals : a reviewPublication . Pereira, Ana Filipa; Baptista, Catarina Jota; Faustino-Rocha, Ana; Oliveira, Paula A.; Coelho, Ana CláudiaRecent advancements in molecular biology have led to the discovery of potential biomarkers for the diagnosis of acute kidney disease (AKD) and chronic kidney disease (CKD). The use of multiple biomarkers in the diagnosis of kidney disease has the potential to enhance both specificity and sensitivity, enabling early detection and intervention that could ultimately reduce morbidity and mortality rates. This review provides an overview of studies on urine and blood biomarkers and examines their utility and significance in various clinical settings. Further and continuous research is needed to support the application of these biomarkers in clinical practice to facilitate early diagnosis, guidance for different interventions, and the monitoring of disease progression.
- The veterinary medicinal products market supply gap : a practical insight based on the Regulation (EU) 2019/6Publication . Nogueira, Rafaela; Baptista, Catarina Jota; Gonçalves, Lio; Coelho, Ana Claúdia; Faustino-Rocha, Ana I.; Purriños, Marta Regueiro; Gonzalo-Orden, José M.; Oliveira, Paula A.The Regulation (EU) 2019/6 establishes that the veterinary prescriptions should follow a cascade, according to their availability of the market. In sum, the veterinarian is authorized to use a medicine for human use only if there is no product available for the same or other therapeutic indication, in the same or another animal species. This study aims to analyse the application of Regulation (EU) 2019/6 in the pharmacological prescription at the Veterinary Hospital of the University of León. A total of 121 clinical cases, 89 dogs (73.55%) and 32 cats (26.45%) were included. Results revealed that 95 medicines were prescribed, 51 (53.68 %) as veterinary medicines and 44 (46.32 %) as human medicines. From the human medicines, 22 (50.00%) did not have a veterinary alternative in the market; four (9.00%) presented a veterinary medicine in the appropriate formulation for the species; 10 (23.00%) had no alternative in the desired formulation; and 8 (18.00%) had no alternatives for the target species. This study suggested that the cascade was not strictly followed, and several reasons may justify it, such as the lack of veterinary products, different formulations, and differences in costs. An effective, safe and sustainable use of the therapeutic option available can only be accomplished with a rational use of the prescription cascade and a correct use of the Regulation (EU) 2019/6.
