- BACKGROUND: To evaluate intervention, implement evidence-based practice and enhance the welfare of dogs with naturally occurring osteoarthritis (OA), access to valid, reliable and clinically relevant outcome measures is crucial for researchers, veterinarians and rehabilitation practitioners. The objectives of the present study were to translate and evaluate psychometric properties, in terms of internal consistency and construct validity, of the owner-reported measure canine brief pain inventory (CBPI) in a Swedish sample of dogs with pain related to OA.RESULTS: Twenty-one owners of clinically sound dogs and 58 owners of dogs with pain related to OA were included in this observational and cross-sectional study. After being translated according to the guidelines for patient-reported outcome measures, the CBPI was completed by the canine owners. Construct validity was assessed by confirmatory factor analysis, by repeating the principal component analysis and by assessing for differences between clinically sound dogs and dogs with pain related to OA. Internal consistency was estimated by Cronbach's α. Confirmatory factor analysis was not able to confirm the factor-structure models tested in our sample. Principal component analysis showed a two-component structure, pain severity and pain interference of function. Two components accounted for 76.8% of the total variance, suggesting an acceptable fit of a two-component structure. The ratings from the clinically sound dogs differed from OA dogs and showed significantly lower CBPI total sum. Cronbach's α was 0.94 for the total CBPI, 0.91 for the pain severity and 0.91 for the pain interference of function.CONCLUSIONS: The results indicate that the translated version of the CBPI is valid for use in the Swedish language. The findings suggest satisfying psychometric properties in terms of high internal consistencies and ability to discriminate clinically sound dogs from OA dogs. However, based on the confirmatory factor analysis, the original factor structure in the CBPI is not ideally suited to measure pain related to OA in our sample and the hypothesis of the presented two-factor structure was rejected. Further research needs to be conducted to determine whether the original psychometric results from CBPI can be replicated across different target groups and particularly with larger sample size.

- Soft tissue mobilization is frequently used in the treatment of sport and companion animals. There is, however, uncertainty regarding the efficacy and effectiveness of these methods. Therefore, the aim of this systematic literature review was to assess the evidence for clinical effects of massage and stretching in cats, dogs, and horses. A bibliographic search, restricted to studies in cats, dogs, and horses, was performed on Web of Science Core Collection, CABI, and PubMed. Relevant articles were assessed for scientific quality, and information was extracted on study characteristics, species, type of treatment, indication, and treatment effects. Of 1189 unique publications screened, 11 were eligible for inclusion. The risk of bias was assessed as high in eight of the studies and moderate in three of the studies, two of the latter indicating a decreased heart rate after massage. There was considerable heterogeneity in reported treatment effects. Therefore, the scientific evidence is not strong enough to define the clinical efficacy and effectiveness of massage and stretching in sport and companion animals.

Forskningsöversikt (refereegranskat)abstract
- Background: Extracorporeal shockwave therapy (ECSWT) is increasingly used to treat different types of musculoskeletal conditions in sport and companion animals. To explore the scientific basis for the treatment, we conducted a systematic review of the literature on ECSWT used in horses, dogs, and cats. Methods: Relevant articles published in 1980–2020 were identified from three major databases. Each article was assessed for risk of bias. Results: The review identified 27 relevant articles on the effects of ECSWT in horses, nine in dogs, but none in cats. Typically, ECSWT involved one to three treatment sessions at 1- to 3-week intervals. We identified studies on bone mass and bone healing, wound healing, navicular disease, ligament injury, desmitis, sesamoiditis, tendon injury, osteoarthritis, and short-term analgesic effects. Common to all indications was that the scientific evidence was very limited. For each separate indication, there were relatively few studies, many of which had methodological flaws. Where favorable results were reported, they were usually not replicated in independent studies. A few encouraging results were found. Conclusions: In sport and companion animals, the scientific evidence for clinical effects of ECSWT in horses, dogs, and cats is limited. For some applications, notably short-term pain relief, ligament ailments, and osteoarthritis, the results seem promising and warrant further exploration in high-quality studies.

Forskningsöversikt (refereegranskat)abstract
- Background: To explore the scientific evidence for therapeutic ultrasound (TU), we conducted a systematic review of the literature on TU in dogs, horses, donkeys, and cats. Methods: In three major databases, relevant articles published in 1980–2020 were identified. The risk of bias in each article was evaluated. Results: Twenty-four relevant articles on the effects of TU in dogs, nine in horses, two in donkeys, and one in cats were identified. TU usually involved 2–6 treatments weekly for up to 4 weeks. Articles on tendon, ligament, and bone healing, acute aseptic arthritis, osteoarthritis, paraparesis, hindquarter weakness, and back muscle pain were identified. In experimental bone lesions in dogs, there is moderate scientific evidence for enhanced healing. For the treatment of other musculoskeletal conditions, the scientific evidence is insufficient due to the high risk of bias. There is substantial evidence that continuous TU increases tissue temperature in muscles and tendons by up to 5 °C in healthy animals. For disorders in tendons, ligaments, muscles, and joints in sport and companion animals, there is insufficient evidence for the clinical effects of TU.

- In Cuba, Classical Swine Fever (CSF) has become an endemic disease since 1993 with several outbreaks each year despite the compulsory vaccination program implemented. To deepen the disease characterization is essential for improving the CSF control measures and to achieve its eradication. The aim of this study was to describe the epidemiological characteristics of CSF occurrences in Cuba during a seven-year period within the endemic situation. Data on CSF occurrence from January 2010 to December 2016 were analyzed. The seven-year period shows a tendency of the number of affected premises to increase (r=0.31, p=0.005) over time (month). Directional distribution (1SD ellipse) indicated a great dispersion of affected premises by year across the country with a trend to a higher occurrence to the west. It was demonstrated by the negative correlation (r=-0.893, p=0.007) between the longitude of the mean center of the ellipses over the years. The Kernel density indicated that the disease was spatially distributed across the whole country, but four hot spots were found in the western (Pinar del Río and Artemisa) and eastern (Guantánamo and Holguín) regions. The clinical sign most frequently reported in affected premises was fever, followed by loss of appetite, conjunctivitis, and diarrhea. The most frequent observed clinical signs were non-specific, which complicates the disease recognition in the field. The obtained results have a practical importance for improving the efficiency of the CSF control program implemented in the country and contribute to enhance epidemiological surveillance taking into account the risk based principles.

- Low-pathogenic avian influenza (LPAI) viruses in wild birds are important as they can constitute the basis for the development of highly pathogenic avian influenza viruses or form part of human-adapted strains with pandemic potential. However, the pathogenesis of LPAI viruses is not well characterized in dabbling ducks, one of the natural reservoirs of LPAI viruses. Between 21 September 2009 and 21 December 2009, we used real-time reverse transcriptase polymerase chain reaction (q-PCR), histopathology, and immunohistochemistry (IHC) to study Mallards (Anas platyrhynchos) infected with an influenza A/H1N1 virus isolated from a wild Mallard in Sweden. The ducks were either inoculated intraesophageally ("artificial infection") or infected by virus shed by other ducks in the experiment ("contact infection"). The ducks were subjected to three low concentrations (80 ng/L, 1 mu g/L, and 80 mu g/L) of the active metabolite of oseltamivir (Tamiflu (R)), oseltamivir carboxylate (OC), which resulted in the development of the viral resistance mutation H274Y at 1 and 80 mu g/L. The LPAI virus infection was localized to the intestinal tract and cloacal bursa except in one Mallard. The exception was a duck euthanized 1 day postinoculation, whose infection was located solely in the lung, possibly due to intratracheal deposition of virus. The intestinal infection was characterized by occasional degenerating cells in the lamina propria and presence of viral antigen as detected by IHC, as well as positive q-PCR performed on samples from feces and intestinal contents. Histopathologic changes, IHC positivity, and viral shedding all indicated that the infection peaked early, around 2 days postinfection. Furthermore, more viral antigen and viral RNA were detected with IHC and q-PCR in the proximal parts early in the infection. There was no obvious difference in the course of the infection in artificial versus contact infection, when the level of OC was increased from 80 ng/L to 1 mu g/L (based on IHC and q-PCR), when the level of OC was increased to 80 mu/L, or when the resistance mutation H274Y developed (based on q-PCR).

- Owners’ ability to recognize signs of chronic pain in dogs undergoing pharmacologic and nonpharmacologic pain interventions during a period of physical rehabilitation is not known. This study aimed to compare dogs with and without chronic pain, and to assess the relationship between explanatory factors, including the probability of owners’ response bias induced by pharmacologic and nonpharmacologic pain intervention, and chronic pain in dogs with osteoarthritis (OA). Seventy-one dogs with OA were included in this observational study. Owner-perceived pain interference was measured by Canine Brief Pain Inventory (CBPI) and owner-perceived pain behavior was assessed using Helsinki Chronic Pain Index. A dichotomous variable of Helsinki Chronic Pain Index was used in regression analysis to investigate the association between chronic pain and explanatory factors (body condition, anti-inflammatory medication, animal physiotherapy consultation once or more and owners’ perception of pain interfering). Seventy-five percent of the dogs had ongoing anti-inflammatory medication, 51% of were overweight and 45% had a physiotherapy consultation. Higher levels of overt pain behaviors were reported in items addressing activities. Body condition, physiotherapy consultation and medication were not associated with chronic pain. Odds ratio (OR) and 95% confidence intervals of OR for the CBPI were 1.74 (1.23-2.47) and significantly associated with chronic pain. The adjusted OR of the CBPI did not differ from the crude OR. Owner-perceived pain behavior was not confounded by the dogs’ medication. Results indicated that CBPI was not mediated by the medication. The CBPI pain interference score was not associated with response bias and may be used as clinical outcome measure of chronic pain and pain-related disability in dogs with OA along a period of physical rehabilitation comprising pharmacologic and nonpharmacologic pain interventions.

- Introduction: Vector-borne canine diseases are a serious danger to animal and human health. The objective of the present study was to determine the prevalence of zoonotic pathogens (Anaplasma platys, Anaplasma phagocytophilum, Borrelia burgdorferi sensu lato, Ehrlichia canis and Rickettsia spp. and non-zoonotic (Hepatozoon canis and Babesia spp.) in ownerless dogs from Havana, Cuba.Methods: Blood samples were collected from 100 dogs and the hematological profiles were studied and pathogens were detected by visualization of blood smears and real-time PCR. To determine the prevalence of infection by Hepatozoon canis, 80 dogs were studied by visualization of blood smears andreal time PCR. For the detection of Babesia spp., 60 dogs were studied, using hematological examination, blood smear visualization and PCR.Results: Eighty-five dogs were positive for at least one pathogen, being E. canis the most prevalent, followed by A. platys and Rickettsia felis, and 36 % showed coinfections. All samples were negative for A. phagocytophilum and B. burgdorferi s.l. These results constitute the first report of R. felis in dogs from Cuba, demonstrate the high prevalence of pathogens transmitted by ticks, with zoonotic potential, and constitute the first study where coinfections are analyzed. 38 % of the dogs were positive for H. canis by PCR and for the first-time molecular characterization of H. canis was carried out in Cuban ownerless dogs and 20 % were positive by PCR for Babesia spp., which constitutes the first molecular evidence of Babesia spp. in ownerless dogs fromCuba.Conclusions, these results are of great importance for the surveillance of vector-borne diseasesin dogs, and demonstrate the need for studies on the prevention of transmission and spread of the diseases they cause.

Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- Exposure to stress is a risk factor for developing pre-menstrual syndrome (PMS) and pre-menstrual dysphoric disorder (PMDD), and stress enhances the anxiogenic effect of female sex steroids in animals. This study examines the interaction between chronic subordination stress and withdrawal from progesterone (P4) and estradiol (E2) (PEWD) in producing behaviors analogous to anxiety and irritability in rats. At the start of the experiment, male Wistar rats were housed in triads consisting of one younger rat (~35 days) and two older rats (~50 days). The housing condition was aimed at producing chronic subordination stress in the younger animals. Chronic subordination stress was assessed by the elevated plus maze (EPM) and by corticosterone (CORT) analysis. A triad of three 35-day-old rats was used as age control. Social rank within the triads was determined using a food competition test (FCT) and the tube test (TT). The younger rats (subordinate) and the dominant rats were assigned to 10 days of treatment with 5 mg/kg progesterone combined with 10 µg/kg 17β estradiol. Twenty-four hours after the last injection, the subordinate and dominant animals were tested in the open-field test (OFT) and in the intruder test (IT). The IT consists of a 10-minute exposure to 3 unfamiliar rats. Chronic subordination stress reduced EPM open-arm time and altered the CORT response. It also made the subordinate animals more vulnerable to PEWD. The effects were increased locomotion in the OFT, increased defensive burying, and increased social anxiety in the intruder test (IT). Dominant animals did not react to PEWD. Thus, chronic subordination stress augments PEWD.
