In Song 2024 et al., on CT vs cystoscopy for ectopic ureters in dogs, what proportion of dogs were misclassified for CLA candidacy based on CT findings alone?
🔍 Key Findings
- CT correctly identified ectopic ureters in 91% of dogs, but missed 50% of normal ureters, limiting its negative predictive value.
- Sensitivity for intramural ectopic ureters was 65%, while specificity was 71%, indicating moderate diagnostic performance.
- Sensitivity for extramural ectopic ureters was only 29%, despite a high specificity of 97%.
- CT was inaccurate in predicting ureteral orifice location, with sensitivity ranging from 0% to 76% depending on the site.
- 26% of dogs were misclassified for cystoscopic laser ablation (CLA) eligibility based on CT findings alone.
- Overall CT accuracy for CLA candidacy was 74%, but a significant minority would have been inappropriately treated.
- Multivariate analysis found no predictive factors (e.g., colon distension, body weight) for when CT would be incorrect.
- Authors recommend confirmatory cystoscopy to verify CT findings prior to treatment planning.

In Buote 2023 et al., on laparoscopic gastrectomy in cats, what percentage of stomach was resected in the cadaver model?
🔍 Key Findings
- LVSG was feasible in 9/10 feline cadavers with successful stapled gastrectomy and minimal technical complications.
- Stenosis at the incisura angularis occurred in 2/10 cadavers, associated with staple placement too close to the lesser curvature.
- Leak testing was negative in 8 cadavers and both live cats, indicating effective staple sealing.
- Mean stomach resection was ~28%, though less than human standards (~75–80%) for metabolic effects.
- Surgery was performed safely in two live feline subjects, with no intraoperative or postoperative complications over a 6-month follow-up.
- Technique refinements included orogastric tube placement and custom 3D-printed cannulas to improve staple line accuracy and avoid stenosis.
- Tri-Staple purple cartridges provided graduated compression suited for feline gastric tissue thickness (~2.5 mm).
- No need for staple line oversew in live cats; staple-only closure proved safe in this short-term study.

In Mazdarani 2025 et al., on simulated muscle loading, which fixation model produced the most physiologic quadriceps forces?
🔍 Key Findings
- Simulated quadriceps and gastrocnemius forces increased proportionally with axial load in all three femoral fixation models.
- Model 2 (rigid fixation) resulted in subphysiologic quadriceps forces and abnormally high gastrocnemius forces, reducing model fidelity.
- Models 1 and 3 (with hip mobility) produced more physiologic quadriceps and force ratios, especially under 30–40% bodyweight loads.
- Force ratios were significantly lower in rigid fixation (Model 2) compared to hip-mobile models (p = .007), suggesting model design affects simulated muscle coordination.
- Joint angles (stifle and hock) remained within acceptable limits, though slight flexion occurred with increasing load.
- Relative foot position differed by ~3.9 mm between models 2 and 3, with model 2 showing a more caudal position.
- Model 3 preserved benefits of hip mobility while allowing radiographic documentation, making it a preferred setup for future studies.
- The study suggests that models used in feline stifle stabilization research may underestimate physiologic forces, especially with rigid fixation designs.

🔍 Key Findings
- No significant difference in cardiac troponin I levels 12h post-op between mDN and St. Thomas cardioplegia groups (p = 0.478)
- Sinus rhythm returned faster in the mDN group after aortic cross-clamp removal (median 60s vs 362s, p = 0.027)
- Lower serum potassium at cross-clamp removal in the mDN group (median 4.5 mEq/L vs 5.4, p = 0.005)
- Fewer doses needed in the mDN group (median 2.5 vs 4.0, p = 0.040)
- Higher total crystalloid volume used in mDN group (23.6 vs 12.6 mL/kg, p < 0.001)
- No difference in survival (700-day survival 90% in both groups, p = 0.958)
- No difference in hospitalization duration (median 6 days for both, p = 0.789)
- Echocardiographic remodeling similar between groups at 24h post-op

In Miller 2024 et al., on SOP-LC mechanical testing, what was the impact of rod contouring on four-point bending strength?
🔍 Key Findings Summary
- No significant difference in mechanical properties between contoured vs non-contoured SOP-LC rods
- Clamp configuration significantly influenced mechanical performance:
- Single-side clamps → ↑ yield load, ↑ displacement, ↑ bending strength (p < 0.05)
- Alternating-side clamps → ↑ initial torsional stiffness (p = 0.029)
- Clamp slippage was evident only in torsional tests; screw loosening may be torque-dependent
- Mild screw bending and construct offset suggest subtle instability
- Recommends clamp configuration choice based on loading scenario
- Suggests 3.0 Nm torque may be more effective than 2.5 Nm to prevent clamp slippage

In Adams 2022 et al., on C-section survival rates, which factor was most strongly associated with improved neonatal survival?
🔍 Key Findings
- Neonatal survival to discharge was 93.1% overall, with no significant difference between brachycephalic (94.8%) and nonbrachycephalic (91.8%) breeds.
- Elective C-section significantly improved neonatal survival (99.2%) compared to emergency C-section (87.1%) (p < .001).
- Larger C-section litter size was positively associated with survival (p = .004; OR 1.57), whereas total litter size had no effect.
- Maternal heart rate and stage of labor were associated with neonatal mortality in univariable analysis, but not multivariable.
- Brachycephalism alone was not a risk factor for neonatal mortality (p = .221) in multivariable analysis.
- Emergency C-section was the strongest predictor of neonatal mortality (OR 4.75), regardless of breed.
- Multidisciplinary team approach likely contributed to high survival rates, emphasizing importance of coordinated care.
- Historical factors such as primiparity and maternal age were not associated with mortality in this cohort.

In Tani 2022 et al., on FCU tendon reconstruction, what did histology of the FCU in Case 1 reveal?
🔍 Key Findings
- Fascia lata autograft reconstruction of the FCU tendon successfully treated carpal hyperextension in both dogs.
- Primary repair was not possible in one dog due to complete rupture; a fascia lata graft bridged the tendon gap.
- In the second case, elongated tendon was corrected and reinforced with fascia lata to prevent recurrence.
- Type I external skeletal fixation was used for 6 weeks to support tendon healing in both dogs.
- Postoperative gait and range of motion returned to normal, with no recurrence at 36-month follow-up.
- Ultrasonography aided diagnosis, revealing thinning and echogenic changes in the FCU tendon.
- Histologic findings showed mild, nonspecific muscle changes, suggesting injury rather than a systemic disease.
- No complications occurred, and fascia lata showed potential for biological integration and remodeling into tendon-like structure.

In Miller 2024 et al., on surgical comparison of staphylectomy vs. FFP, what was the most common postoperative complication overall?
🔍 Key Findings
- FFP resulted in longer median surgery (75 min) and anesthesia (111 min) durations than S (51 min and 80 min, respectively).
- No significant difference in anesthetic complications, regurgitation, aspiration pneumonia, or hospitalization time between S and FFP.
- Major complications were rare (4%) and equally distributed between procedures; included tracheostomy and euthanasia due to severe airway disease.
- Postoperative oxygen use was common (52% of dogs) but not significantly different between procedures.
- FFP dogs more often had laryngeal collapse (especially Grade 1: 68% vs. 32% in S dogs).
- Most dogs (85%) had concurrent nares surgery, with caudal wedge resection more frequent in FFP dogs.
- Few dogs needed revision soft palate surgery (7/124 total); similar between groups.
- Postoperative clinical signs improved across both procedures; regurgitation was the most persistent sign post-op.
