In İnal 2025 et al., on feline high-rise trauma, what was the area under the ROC curve (AUC) for ATTS in predicting mortality?

Thank you! Your submission has been received!
Oops! Something went wrong while submitting the form.
Correct. The AUC was 0.857, indicating good predictive performance for ATTS
Incorrect. The correct answer is 0.86.
The AUC was 0.857, indicating good predictive performance for ATTS

🔍 Key Findings

Sample: 373 cats with high-rise syndrome (HRS) from 2017–2020.
ATTS was the only significant predictor of survival (p < 0.001); each point increase decreased survival odds (OR = 0.46).
AUC for ATTS ROC curve: 0.857 (95% CI: 0.788–0.926).
Floor height, lesion type, and ground surface were not significantly associated with survival.
Odds of injury were 7.98× higher when landing on hard vs. soft surface (p < 0.001).
16.96× increased injury risk from the fourth vs. third floor (p = 0.008).
Cats with ATTS ≥7 had 62% mortality; median ATTS increased with floor height (r = 0.244, p < 0.001).
Thoracic and vertebral trauma were most common causes of death.
Only 32% of cats had the “classic” HRS triad (pneumothorax, epistaxis, hard palate fracture).

In Silveira 2022 et al., on GTO in canine THR, which scenario was considered a suitable indication for performing a greater trochanter osteotomy?

Thank you! Your submission has been received!
Oops! Something went wrong while submitting the form.
Correct. GTO was used specifically in cases with severely medialized trochanters or fixed luxations limiting broach access.
Incorrect. The correct answer is Severe medialization of the greater trochanter or chronic craniodorsal hip luxation.
GTO was used specifically in cases with severely medialized trochanters or fixed luxations limiting broach access.

🔍 Key Findings

  • GTO enabled successful cementless THR in dogs with severe medialization of the greater trochanter or chronic craniodorsal hip luxation.
  • All 5 hips had acceptable long-term outcomes (median follow-up: 48 months) with full function and no persistent complications.
  • Only one major complication occurred—a luxation unrelated to the GTO and successfully corrected with cup revision.
  • GTO facilitated femoral canal access and gluteal preservation, reducing risk of iatrogenic injury during broaching.
  • All GTOs healed radiographically (4 by 6 weeks, 1 by 12 weeks), with no cases of nonunion or implant migration.
  • No complications related to GTO or PTBW fixation (pins + tension band) were observed in any dog.
  • Surgical planning included templating both THR and GTO to ensure ideal alignment and reduce fracture risk.
  • GTO may be especially valuable in luxoid hip dysplasia phenotypes or chronically fixed luxations.

In Sabol 2024 et al., what was the narrowest documented corridor width in thoracic vertebrae?

Thank you! Your submission has been received!
Oops! Something went wrong while submitting the form.
Correct. Widths as small as 1.8 mm were documented in the mid-thoracic spine, highlighting surgical risk:contentReference[oaicite:0]{index=0}
Incorrect. The correct answer is 1.8 mm.
Widths as small as 1.8 mm were documented in the mid-thoracic spine, highlighting surgical risk:contentReference[oaicite:0]{index=0}

🔍 Key Findings Summary

  • Evaluated ideal dorsolateral implant trajectories in T1–T13 using CT in 30 dogs across five weight classes.
  • Corridor widths were narrowest in the mid-thoracic vertebrae (as little as 1.8 mm) and increased cranially and caudally.
  • Allowable deviation angles (ADA) were often very small (as little as ), indicating high risk for canal or thoracic structure breach.
  • Distances to critical structures (lungs, aorta, subclavian artery, azygos vein) were often <1 mm, even in large dogs.
  • Data suggest extreme caution and precision are needed for thoracic vertebral implant placement and support use of navigation or 3D-printed guides.

In Burkhardt 2024 et al., on coagulation testing in liver lobectomy, which liver tumor type was significantly associated with both PT and aPTT prolongation?

Thank you! Your submission has been received!
Oops! Something went wrong while submitting the form.
Correct. Only hemangiosarcoma showed a significant association with both PT and aPTT prolongation (p < .001).
Incorrect. The correct answer is Hepatic hemangiosarcoma.
Only hemangiosarcoma showed a significant association with both PT and aPTT prolongation (p < .001).

🔍 Key Findings

  • 20.6% of dogs had a preoperative prolongation in PT or aPTT, but only 5.6% had both prolonged.
  • Hemangiosarcoma was the only tumor type significantly associated with both PT and aPTT prolongation (37.5% of hemangiosarcoma cases, p < .001).
  • Dogs with both PT and aPTT prolongations were 6.5× more likely to have emergency surgery (p < .001) and 2.5× more likely to have hemoabdomen (p = .0022).
  • 60% of dogs with both PT and aPTT prolongation required blood transfusion (p < .001).
  • Only 1.9% of all dogs had both PT and aPTT prolonged by >25%, suggesting limited clinical utility of routine PT/aPTT testing.
  • Platelet count <50,000/μL was rare (1.5%) and not associated with PT/aPTT changes or transfusions.
  • Routine PT/aPTT testing offers low diagnostic yield in elective liver lobectomy cases.
  • Authors recommend case-by-case PT/aPTT screening, especially when hemangiosarcoma or bleeding tendencies are suspected.

In Dobberstein 2022 et al., on NSAID ulcer repair, what clinical parameter was associated with a trend toward increased risk of death?

Thank you! Your submission has been received!
Oops! Something went wrong while submitting the form.
Correct. Each 1 mmol/L increase in serum lactate doubled the risk of postoperative mortality.
Incorrect. The correct answer is Hyperlactatemia.
Each 1 mmol/L increase in serum lactate doubled the risk of postoperative mortality.

🔍 Key Findings

  • Primary repair of NSAID-associated full-thickness gastroduodenal ulcers was successful in 73% (8/11) of cases.
  • NSAID overdose, concurrent corticosteroid use, or extended duration were identified in 9/11 dogs and were major contributors to ulceration.
  • All perforations were in the pylorus or proximal duodenum, locations suitable for primary closure.
  • No significant association between ulcer size or location and postoperative survival.
  • Preoperative hyperlactatemia trended toward increased mortality (P = .0544; OR 2.045).
  • Postoperative vasopressor use was linked with a 9-fold increased risk of mortality (P = .0545).
  • Dehiscence was rare, suspected in only 1 of 11 cases, indicating that primary repair is structurally sound in selected cases.
  • Median follow-up of 444 days showed long-term survival was achievable post-primary repair.

In Mazdarani 2022 et al., on CBLO and stifle biomechanics, when did cranial tibial translation (CTT) occur after CBLO **without** hamstring loading?

Thank you! Your submission has been received!
Oops! Something went wrong while submitting the form.
Correct. CBLO eliminated CTT at all angles **except 140°** in the absence of hamstring load.
Incorrect. The correct answer is Only at 140°.
CBLO eliminated CTT at all angles **except 140°** in the absence of hamstring load.

🔍 Key Findings

  • CBLO reduced tibial plateau angle (TPA) from a mean of 28.1° to 9.7°, aligning with its goal of flattening the tibial slope.
  • CBLO eliminated cranial tibial translation (CTT) following CCL transection and meniscal release at all angles except 140° without hamstring load.
  • Hamstring loading (20% quadriceps load) significantly reduced or delayed the onset of CTT, improving stifle stability.
  • Medial meniscus was confirmed as a secondary stabilizer; its release (MMR) caused more CTT than CCLx alone.
  • PTA (patellar tendon angle) increased with joint extension; CBLO shifted the PTA curve lower and parallel to intact values, suggesting effective flexion of the joint.
  • Combined CBLO and hamstring loading resulted in the most stable joints, especially from 50° to 135° joint angles.
  • Residual CTT occurred in CBLO-only limbs at higher extension angles (e.g., 140°), but hamstring load mitigated this.
  • Stifle stability post-CBLO is multifactorial, depending on joint angle, meniscal integrity, and hamstring activation.
