Sildenafil alone (0.69 mg/kg, PO, BID) was prescribed post-discharge to address PH without diuretics. Post-discharge from the referral veterinary hospital, collapse and pre-syncope were suspected to be due to PH. Consequently, sildenafil was titrated weekly, starting at 1.09 mg/kg BID and increasing to 1.63 mg/kg BID. Pre-syncope and collapse resolved, and pulmonary opacities reduced considerably, although concerns remained that increased pulmonary blood flow to suspected CTS from sildenafil might worsen cardiogenic pulmonary oedema. The patient was also treated with rivaroxaban (2.5 mg/head, SID), considering the increased risk of thrombus formation due to blood flow stasis and endothelial damage. Thirty-eight days later, the cat presented for the first time to our hosipital (Azabu University Veterinary Teaching Hospital) for examination. On echocardiography, a continuous mosaic blood flow (maximum and minimum velocity, 3.14 m/s; estimated pressure gradient, 39.4 mmHg) was observed in two enlarged pulmonary veins. Pulmonary artery enlargement (main pulmonary artery to thoracic aorta ratio: 1.90), pulmonary vein stenosis (PVS), and diffuse bilateral ground-glass lung opacities were observed using computed tomography. PH with unilateral PVS involving two out of the three right pulmonary veins, specifically the right cranial and right middle pulmonary veins, along with pulmonary parenchymal disease, was diagnosed. The cat was further treated with furosemide (1 mg/kg, BID, PO) with no clinical signs but succumbed to acute dyspnoea 51 days after the first visit.</p><p><strong>Conclusions: </strong>Unilateral PVS should be considered in young cats with a localised alveolar pattern and no left atrial enlargement, because the prognosis may be poor. Severe PH with PVS may coexist with lung disease.

Nonpedigree cats are also affected, but the incidence is unknown. The causes of dystocia and the optimal treatment are largely unexplored in cats. The aims of the present retrospective study were to describe feline dystocia cases and to evaluate kitten mortality in relation to factors associated with dystocia in cats. Medical records of 111 cases (107 queens) treated for dystocia from 2017 to 2024 were retrieved from client files at the University Animal Hospital in Uppsala, Sweden. At the initiation of treatment, 276 kittens remained in utero or in the birth canal. The total kitten mortality rate, including that of kittens born before treatment but excluding four kittens that were euthanized at the owner's request, was 40.9%. The mortality of kittens born after treatment was 44.1%, excluding four kittens euthanized at the owner's request. Two queens died, one of which was euthanized at the owner's request. Among all the cases, 91 (82.0%) were surgically treated, with caesarean section, or en bloc resection in two patients. Ovariohysterectomy was performed in 47.2% of the queens that were surgically treated. Medical treatment was initiated in 30 patients, and was successful in 11 of them, and 19 were further surgically treated after only partial or no success. The success rate of medical treatment was thus 36.7%. Eight queens were hypocalcaemic. Maternal hyperglycaemia was present in 65.5% of the cases and significantly increased the risk of kitten mortality. The estimated duration of second-stage labour before admission did not affect kitten mortality. Disturbed labour (total or partial uterine inertia) was the most common cause of dystocia. Feline dystocia was associated with high kitten mortality but low mortality in queens. Most queens with dystocia were treated surgically, but medical treatment with calcium and/or oxytocin was efficient in cases with non-obstructive dystocia, and ≤ 3 foetuses remaining. Hypocalcaemia may contribute to dystocia in a minority of cases. Maternal hyperglycaemia increased the risk of mortality before discharge.

However, these inspections can also be useful for detecting animal health and welfare issues. In cattle, traumatic injuries from on-farm incidents, transport or handling at the slaughterhouse are indications of both reduced animal welfare and increased risk of food waste, ultimately resulting in economic losses for both farmers and slaughterhouses. This observational study aimed to investigate the prevalence and seasonal variation of traumatic injuries in cows and heifers reared on organic and conventional farms in Sweden. The study includes slaughter remarks and condemnations from meat inspection data from 336,071 animals slaughtered between 2020 and 2022. Two types of injuries were analysed: \"chronic traumatic injuries\" (CTI) sustained on-farm and \"acute traumatic injuries\" (ATI) sustained during transport or at the slaughterhouse. Logistic regression models were developed to assess the influence of production system and season. Results show a higher prevalence of CTI in animals from conventional farms (9.8%) compared to organic farms (6.9%; P < 0.001), which may indicate that animals from organic farms are managed and handled in a way that makes them better prepared for challenges that they are later exposed to on-farm prior to slaughter. ATI were more frequent in animals from organic farms during the grazing period (interaction between production system and season: P = 0.002), which may indicate that animals from organic farms find the transition to the slaughterhouse environment more abrupt and stressful during the grazing period. Condemnations due to injuries were significantly higher for animals with CTI or ATI compared to animals without these specific remarks. These findings highlight the importance of pre-slaughter management, both on-farm and at the slaughterhouse, and slaughterhouse design in improving animal welfare and reducing food as well as economic losses associated with carcase condemnations.</p>","PeriodicalId":7181,"journal":{"name":"Acta Veterinaria Scandinavica","volume":"67 1","pages":"18"},"PeriodicalIF":1.9,"publicationDate":"2025-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11987234/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143959870","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Reindeer bulls removed from breeding are clamp castrated, traditionally without analgesia, and then returned to the grazing grounds. The new Finnish Animal Welfare Act requires the use of analgesia in painful procedures. Our earlier studies have shown that a single dose of the non-steroidal anti-inflammatory drug (NSAID) meloxicam may maintain therapeutic plasma concentrations for 2-3 days in reindeer. No studies have been conducted on the effect of meloxicam on the locomotor activity of free-ranging castrated reindeer after castration. We installed GPS collars on 16 male reindeer (at least 5 years old, 130-160 kg), chosen to be castrated as a standard procedure during the round-up held on 5 Oct 2020. Of these, eight were randomly selected to receive approximately 0.5 mg/kg of meloxicam subcutaneously (NSAID group) and eight received no analgesia (TRAD group). The trackers were set to provide location twice per hour with 10 m accuracy. From the GPS data, we calculated the daily distances travelled by the reindeer during the 3 days after castration and analysed the differences between the treatments using a GEE model.

In Sweden, during the last decades, resistance to trimethoprim-sulphonamide and ampicillin has increased markedly in E. coli from routine clinical samples from piglets with diarrhoea, hereafter referred to as \"clinical submissions\". This has occurred despite a comparatively low use of antibiotics in Swedish pig production. However, clinical submissions might be biased towards farms with treatment failures and therefore overestimate occurrence of AMR. To explore the representativeness of data from such samples we compared occurrence of AMR in E. coli from clinical submissions and from concurrent samples collected from piglets with diarrhoea by convenience, referred to as \"study samples\".
