Background
Published information regarding survival and long‐term cardiac remodeling after patent ductus arteriosus (PDA) closure in dogs is limited.Objectives
To report outcome and identify prognostic variables in dogs with PDA, and to identify risk factors for persistent remodeling in dogs with a minimum of 12 months of follow‐up after closure.Animals
Five hundred and twenty client‐owned dogs.Methods
Retrospective review of medical records of 520 dogs with PDA. Outcome was determined by contacting owners and veterinarians. Dogs with PDA closure and ≥ 12 months of follow‐up were asked to return for a re‐evaluation.Results
In multivariable analysis of 506 dogs not euthanized at the time of diagnosis, not having a PDA closure procedure negatively affected survival (HzR = 16.9, P < .001). In 444 dogs undergoing successful PDA closure, clinical signs at presentation (HzR = 17, P = .02), concurrent congenital heart disease (HD) (HzR = 4.8, P = .038), and severe mitral regurgitation (MR) documented within 24 hours of closure (HzR = 4.5, P = .028) negatively affected survival. Seventy‐one dogs with ≥ 12 months follow‐up demonstrated a significant reduction in radiographic and echocardiographic measures of heart size (P = 0) and increased incidence of acquired HD (P = .001) at re‐evaluation. Dogs with increased left ventricular size and low fractional shortening at baseline were more likely to have persistent remodeling at re‐evaluation.Conclusions and Clinical Importance
Patent ductus arteriosus closure confers important survival benefits and results in long‐term reverse remodeling in most dogs. Clinical signs at presentation, concurrent congenital HD, and severe MR negatively affect survival. Increased left ventricular systolic dimensions and systolic dysfunction at baseline correlated significantly with persistent remodeling. 相似文献2.

This study evaluated outcomes of surgical treatment of equine sialolithiasis, highlighting cases involving the proximal parotid salivary duct. Sialoliths in the proximal parotid duct were difficult to identify radiographically and more frequently associated with draining tracts and sialadenitis compared with sialoliths in the distal parotid duct. Ultrasonography confirmed the diagnosis of sialolithiasis in all cases in which there was no radiographic evidence of a sialolith. All cases of proximal parotid duct sialolithiasis required transcutaneous removal. A longer duration of illness was observed in cases of proximal parotid duct sialolithiasis compared with cases involving the distal parotid duct, and in cases requiring transcutaneous removal compared with cases requiring transoral removal. Recurrence of sialolithiasis was documented in 24% of cases, all of which were located in the distal parotid duct. The average time to recurrence was 2.8 years. 相似文献

This retrospective study reports long-term outcome, survival, and complications in dogs which received a permanent tracheostomy due to upper airway obstruction. Data were collected from medical records (n = 21) in 2 institutions over a 12-year period. Patients were followed until death, complications, causes of death, and survival times are reported. Major complications were reported in 50% of patients with 20% of patients receiving revision surgery. The most common complications were aspiration pneumonia and need for revision surgery. Median survival time was 328 days with 25% of patients surviving 1321 days or longer. Some (26%) patients died acutely at home at various times after surgery. Permanent tracheostomy is a viable procedure for patients with end stage upper airway obstruction; however, a subpopulation of patients suffers acute death at various times after surgery, which is thought to be due to airway obstruction. 相似文献

Multidrug-resistant (MDR) bacteria are an emerging threat in human and veterinary medicine. There are few reports about infections caused by MDR isolates in horses. The aim of this study was to provide an overview of infections caused by MDR bacteria at the Equine Hospital Zurich between 2012 and 2015. Medical records were searched for horses with confirmed MDR bacterial infection. Multidrug resistance was defined according to human guidelines specific for each pathogen. MDR isolates were most commonly isolated from post-procedural infections (53/110, 48%), followed by musculoskeletal (16/110, 15%) and soft tissue infections (16/110, 15%). Escherichia coli (32/158, 20%) and Staphylococcus aureus (25/158, 16%) were the most common isolates. High resistance rates precluded therapy with commonly used antimicrobial drugs. The overall mortality rate was 20% (22/108) but depended on the localisation of the infection. Antimicrobial treatment prior to development of infection was reported for 89% (91/102) of horses. This study showed that MDR pathogens, mainly MDR E. coli and MRSA, cause a considerable number of infections in horses. A wide range of infections was seen, however, nosocomial infections predominated. These cases are typically hospitalised, pretreated with antibiotics, and suffering from comorbidities putting them at high-risk for acquiring infections caused by MDR isolates. The mortality of such infections was generally low but depended on site of infection. 相似文献

This retrospective case series reports on the clinical experiences of a group of Thoroughbred racehorses in training that were treated surgically for intermittent dorsal displacement of the soft palate (DDSP) using sternothyroideus tenectomy in combination with soft palate surgery. The 95 horses included in the study were Thoroughbred racehorses in training referred for surgical treatment of intermittent DDSP over a 10-year period. Return to racing was 94% (89/95). Total earnings increased for up to three starts before and after surgery in 65% of horses (62/95, P= .0006). Of the 58 horses that raced in three or more races before and after surgery, 71% (41/58) improved their total earnings. Mean days to first start were 106 days. Performance index improved in 64% of these horses (37/58). Sixty of the 95 horses (63%) raced in six or more races after surgery. Sternothyroideus tenectomy combination surgery had a good prognosis for improving earnings and performance index after surgery in this group of horses that were treated for a working diagnosis of intermittent DDSP. 相似文献

Several surveillance techniques have been used to quantify the prevalence of both classical and atypical scrapie in British sheep, namely the recording of clinical suspects (RC) and the testing of animals slaughtered at abattoir (AS) or reported as fallen stock (FS). Any estimate of prevalence based on a particular source is likely to have been affected by demographic differences in the populations sampled. In this study, the demographic characteristics of scrapie-affected holdings detected by each of the surveillance streams (RC, AS, FS) in Great Britain were compared. Analyses of all three streams indicated that the probability of an affected holding being detected by a particular stream differed by geographical area, the number of animals brought onto the holding, the type of scrapie identified (classical vs. atypical) and the year. More detailed analysis of AS and FS suggested that the annual and regional differences between these surveys could be explained by differences in sampling effort. 相似文献

1. The effect of lactic acid marination at 5°C on post mortem changes in breast muscle pectoralis major of spent layer Tsaiya duck was studied.
2. Myofibrils were prepared from 0.1 M and 0.2 M lactic acid marinated muscle and control (non‐marinated samples) sampled at 0, 1, 3, 7 and 14 d post mortem.
3. Changes in myofibril fragmentation index (MFI), myofibrillar proteins and Z‐line structure were examined.
4. Marination of duck breast muscle in lactic acid at 5°C enhanced fragmentation of myofibrils and degradation of myofibrillar proteins and Z‐line structure as compared to control samples.
5. In summary, lactic acid marination at 5°C can accelerate the post mortem degradation of myofibrils in Tsaiya duck breast muscle. 相似文献

A monitoring program of the pre-treatment susceptibility of clinical isolates of bacteria from diseased dogs and cats was active between the years 2002 and 2009. Susceptibility of each isolated strain to a panel of nine antibiotics (amoxicillin/clavulanic acid, ampicillin, penicillin, clindamycin, doxycycline, enrofloxacin, marbofloxacin, trimethoprim and trimethoprim/sulfamethoxazole) was assessed. The Minimum Inhibitory Concentration (MIC) of marbofloxacin was also determined by a standardized microdilution technique following CLSI recommendations. In total, 1857 bacterial strains were collected throughout Europe from cases of otitis, respiratory, urinary and dermatological infections. Although bacterial susceptibility varied for each of the antibiotics within the panel, patterns of susceptibility were similar to those described in the literature for comparable time periods and geographical areas. With a clinical resistance varying from 0 to 14.48% against the isolated strains, marbofloxacin susceptibility was very high and remains an effective antibiotic for the treatment of otitis, urinary, respiratory and dermatological infections in companion animals. 相似文献

Equine Welfare and Carriage Horse Companies have been recently highlighted as matters of public concern, although little data exists to describe working conditions, municipal regulations, and veterinary attention. In light of the current pandemic of unwanted horses in this country, it is prudent for the veterinary community to identify objective measurements of satisfactory equine welfare in the carriage horse industry to regulate and maintain working horses in sound conditions. Retrospective data from a carriage company in South Carolina was collected from 2009 to 2012. Variables included days in work, hours and/or tours worked, veterinary charges, management practices, and environmental conditions. City veterinary reports were also reviewed for all five local carriage companies. The average number of days in work per animal ranged from 163 to 188 per year. On average, each animal performed 4.6 hour long tours per working day, resulting in an average 865 tours per year. Each animal cost on average $2.00 per day in veterinary costs, and $0.84 of each animal's tour went toward veterinary bills. Welfare among carriage horses is a subject on which equine veterinarians should be well versed; not only to answer questions from clientele but also to promote good working and living conditions for these animals in an effort to stem the number of unwanted horses in America. The carriage company reported in detail here provides acceptable welfare for their animals. Prospective studies are needed to collect objective, evidence-based data regarding stress levels in the animals. 相似文献
