The purpose of the study was to report the postoperative outcome, complications, and long-term follow-up of the use of a static hydraulic urethral sphincter for the management of urethral sphincter mechanism incompetence in female dogs. Medical records were reviewed to extract information on long-term (>365 days) outcome data. Telephone owner questionnaire was performed to assess postoperative urinary continence scores (scale 1-10, where 10 is complete continence) and the presence and frequency of complications. Twenty female dogs were included. Mean (±standard deviation) time to follow-up was 1,205.1 (±627.4) days. Median continence score/10 (range) was 3.5 (2-6) preoperatively, and 9.0 (7-10) at the last follow-up. Median continence score was significantly higher at all time points postoperatively compared with before surgery (P < .001). Complete continence was achieved in 90% of bitches. Minor complications occurred in 13 bitches and included dysuria (8), bacterial cystitis (8), longer urination time (10), incisional seroma (5), urinary retention (3), hematuria (2), and pain when urinating (2). Major complications occurred in one dog (static hydraulic urethral sphincter removed 28 mo after placement). Continence scores were sustainably improved in the long-term. Complications were mostly minor. Urinary tract infections were the most common but resolved with conventional antibiotic treatment.

Cache management policies should consider workloads’ contention behavior when managing a shared cache. Prior art makes estimates about shared cache behavior by adding extra logic or time to isolate per workload cache statistics. These approaches provide per-workload analysis but do not provide a holistic understanding of the utilization and effectiveness of caches under the ever-growing contention that comes standard with scaling cores. We present Contention Analysis in Shared Hierarchies using Thefts, or CASHT, 1 a framework for capturing cache contention information both offline and online. CASHT takes advantage of cache statistics made richer by observing a consequence of cache contention: inter-core evictions, or what we call THEFTS. We use thefts to complement more familiar cache statistics to train a learning model based on Gradient-boosting Trees (GBT) to predict the best ways to partition the last-level cache. GBT achieves 90+% accuracy with trained models as small as 100 B and at least 95% accuracy at 1 kB model size when predicting the best way to partition two workloads. CASHT employs a novel run-time framework for collecting thefts-based metrics despite partition intervention, and enables per-access sampling rather than set sampling that could add overhead but may not capture true workload behavior. Coupling CASHT and GBT for use as a dynamic policy results in a very lightweight and dynamic partitioning scheme that performs within a margin of error of Utility-based Cache Partitioning at a 1/8 the overhead.

Oral presentations[ 544 ] BSAVA CONGRESS 2017 PROCEEDINGS thoracic cavity was most commonly penetrated (n=35). Diagnostic imaging (all modalities combined) was sensitive and specific to identifying wooden material in 56% and 95% of cases respectively and surgical retrieval of a foreign body or its fragments was required in 20 cases (37%). Thoracotomy was performed in 56% of the cases. Complications occurred in 20 dogs (37%) and of these 70% were minor, 10% major and 20% catastrophic. STATEMENTDespite the often seen dramatic presentation of impalement injuries the majority of treated patients can achieve good outcomes. These injuries require thorough diagnostic imaging and interpretation prior to adequate surgical exploration and management, augmented by anaesthetic and critical care during the peri-and postoperative periods; therefore stable patients should be referred to centres able to provide this type of care. OBJECTIVESThe objective of this study was to retrospectively compare two cohorts of dogs surgically treated for single congenital extrahepatic portosystemic shunts by thin film banding or placement of an ameroid constrictor. METHODSMedical records of dogs with congenital extrahepatic portosystemic shunts treated by thin film banding or ameroid constrictor placement from 2009 to 2016 were reviewed for breed, age at surgery, duration of surgery, postsurgical complications, duration of hospitalisation, pre-and postoperative biochemical analysis, clinical outcome and requirement for repeat surgery. Data were reported with summary statistics. RESULTSForty-nine dogs were treated with thin film banding and 23 were treated with ameroid constrictors based on surgeon preference. In the thin film banding group 10% of dogs died or were euthanased post-operatively compared to 4% in the ameroid group. Postoperative complications occurred in 24% of dogs treated by thin film banding and 22% of dogs treated with ameroid constrictors. Repeat surgery for further attenuation, due to persistent shunting was performed in 20% of dogs treated by thin film banding compared with 9% treated with ameroid constrictors. STATEMENTOur results suggest that ameroid constrictor placement is associated with lower postoperative mortality and a reduced need for second surgery compared to thin film banding. A relatively high rate of persistent shunting prompting additional surgery was seen in the dogs treated with thin film banding, suggesting that this method may not result in complete shunt attenuation in a significant proportion of animals, contrary to previously published findings.
