In Mullen 2024 et al., on NIRF for GDV, what was the typical NIRF finding in histologically confirmed necrotic gastric regions?
🔍 Key Findings
- NIRF altered surgical strategy in 3 of 20 GDV dogs, identifying necrosis not appreciated subjectively.
- Fundic fluorescence <10% indicated histologically confirmed gastric necrosis.
- In 1 dog, NIRF revealed nonviability despite the surgeon’s impression of viability.
- Staple line fluorescence resembled viable tissue in the only stapled gastrectomy, suggesting preservation of perfusion.
- GDV dogs (even “viable”) showed lower fluorescence vs. healthy controls, indicating subclinical vascular compromise.
- Histology confirmed full-thickness necrosis in all 4 dogs with NIRF-defined nonviability.
- Pre-op lactate was significantly higher in nonviable GDV dogs (8.55 vs 4.89 mmol/L, p=0.03).
- No complications were reported from ICG use; imaging was safe and repeatable.

In Nash 2024 et al., on esophageal pH monitoring, what percentage of dogs experienced proximal GER events during the recording period?
🔍 Key Findings
- Esophageal pH-monitoring was well tolerated in all 35 nonbrachycephalic dogs, with no major adverse events reported.
- Distal GER occurred in 80% of dogs, but events were typically brief and non-productive; proximal GER occurred in only 39%.
- Upper reference limits for GER were 2.4 events/hour (distal) and 0.4 events/hour (proximal).
- Cumulative acid exposure was minimal: upper limits were 2.3% (distal) and 0% (proximal).
- Comparison with brachycephalic dogs shows significantly higher GER frequency and duration, validating the diagnostic utility of pH monitoring.
- Transnasal probe placement under light anesthesia was safe and less morbid compared to percutaneous or conscious techniques.
- No expelled or productive regurgitation occurred, despite some GER events, indicating efficient esophageal clearance in healthy dogs.
- Diet and fasting duration may affect GER, but these were not controlled variables in this study.

In Butare-Smith 2022 et al., on cerclage knot biomechanics, what was concluded about the clinical use of double-loop cerclage?
🔍 Key Findings
- Double-loop cerclage resisted the highest peak load (805 N) and maintained tension longer than twist (488 N) and single-loop (397 N) configurations.
- Double-loop cerclage sustained 500,000 cycles at 60–80% of peak load in some cases without loosening, outperforming other types.
- Twist knots loosened rapidly, often within 10 cycles even at low loads (100–390 N).
- Single-loop knots performed better than twist, with partial resistance up to 100,000 cycles at 160 N, but showed wide variability.
- All loosening occurred before wire breakage, indicating clinical failure would happen from slack, not fracture.
- Double-loop cerclage had highest initial tension (323 N) compared to single-loop (124 N) and twist (69 N).
- Fatigue limit was not identified for twist, since they all loosened early at even 20% of peak load.
- Clinical recommendation: double-loop cerclage is best for resisting repeated subfailure loading, ideal for fissure prevention or fragment stabilization.

In Banks 2024 et al., what patient factor was associated with higher preoperative and postoperative TPAs?
🔍 Key Findings Summary
- Study Design: Retrospective study of 100 radiographs using in silico and clinical data
- Mean preoperative TPA: 28.6°, higher in small dogs than large (p = .02)
- Mean planned TPA (in silico): 7.6°, not achieving 5° target (p < .01)
- Median postoperative TPA: 5.5° overall; higher in small dogs (7°) vs large (4.5°) (p = .06)
- Postoperative ostectomy position: More distal than recommended; average = 8.6 mm
- Increased distalization → greater under-correction of TPA (p = .01)
- Most accurate correction occurred when ostectomy was ≤7.5 mm from patellar tendon
- Wedge angle categories (TPA-Pre minus 5–2°) were used based on pre-op TPA

In Clarke 2022 et al., on nasopharyngeal collapse severity, which diagnostic modality was used to quantify pharyngeal collapse in awake dogs?
🔍 Key Findings
- Nasopharyngeal collapse was significantly more severe in brachycephalic dogs (median 65%) than in nonbrachycephalic controls (median 10%) (p = .0001).
- Postoperative fluoroscopy showed no significant improvement in nasopharyngeal collapse (p = .0505), despite reported clinical improvement.
- 70% of brachycephalic dogs had ≥50% collapse; 26% had 100% collapse preoperatively.
- All owners of surgical cases reported clinical improvement, including reduced respiratory noise and improved exercise tolerance.
- Surgical techniques used included combinations of alaplasty, staphylectomy, sacculectomy, and tonsillectomy.
- Improvement in nasopharyngeal dimensions was variable, with some dogs improving ≥45%, some worsening, and one dog showing a 100% increase post-op.
- Pharyngeal collapse may not be solely anatomical; neuromuscular dysfunction (e.g., reduced pharyngeal dilator muscle function) may contribute.
- Current surgical techniques may not address functional airway abnormalities, suggesting a need for multimodal or targeted interventions.

In Huerta 2025 et al., on leakage in canine lung lobectomy, what was the leakage pressure threshold exceeded by most total lobectomy (TL-30) stapled specimens?
🔍 Key Findings
PL-30 group (partial, TA30-V3 wedge):
- 100% leaked
- Median leakage pressure: 10 cm H₂O
- Most failures from periphery of staple line
PL-60 group (partial, TA60-3.5):
- 100% leaked
- Median leakage pressure: 18 cm H₂O
- Better than PL-30 (p = .006)
TL-30 group (total, TA30-V3):
- Only 1 of 11 leaked (at 22 cm H₂O)
- All others resisted pressures >50–65 cm H₂O
- Significantly higher leakage pressure than both PL groups (p < .001)
Odds ratios (leakage vs TL-30):
- PL-30: OR 437 at both 20 and 30 cm H₂O (p = .003)
- PL-60: OR 437 at 20 cm H₂O and 133 at 30 cm H₂O (p = .003)
Recommendation: Prefer TL-30 when possible. If partial needed, PL-60 superior to PL-30, but all partials leaked at physiologic pressures.

In Jeong 2025 et al., on contoured saw guide vs jig, what was observed regarding *surgical time*?
🔍 Key Findings
- TPLO with the contoured saw guide achieved more accurate osteotomy angles for both inclination and torsion in bone models and cadaveric limbs (p < .05).
- Medial cortical damage was significantly lower with the contoured guide (247 vs. 1866 pixels in bone models; p < .001).
- No significant difference in eccentricity (distance between actual and intended osteotomy center) was found between groups.
- Postoperative tibial plateau angle (TPA) was similar between groups (6.4° vs. 7.6°; p = .15), though both were slightly higher than the target of 6°.
- Deviation in medial mechanical proximal tibial angle (mMPTA) showed no significant group difference; valgus deformity occurred in both.
- Osteotomy and device application times were similar between the contoured guide and jig-assisted TPLO.
- The contoured guide eliminated the need for proximal jig pin, potentially reducing intra-articular pin risk.
- The guide's multiple pin fixation system improved stability and alignment, supporting safer osteotomy on curved tibial surfaces.

In Walker 2022 et al., on TPLO mRUST scoring, which of the following was associated with **lower** mRUST scores?
🔍 Key Findings
- TPLO mRUST scoring showed improved inter-rater reliability (ICC = 0.56) compared to subjective evaluation (Kappa = 0.33).
- Intra-rater reliability was similar for both methods (TPLO mRUST: 0.73, subjective: 0.72).
- TPLO mRUST scores ≥10/12 strongly correlated with radiographic union, as subjectively assessed (99% agreement).
- No significant difference in healing between first and second TPLO sides (P = .09), countering assumptions about load-bearing impact.
- Higher initial lameness scores and younger age were associated with higher TPLO mRUST scores, suggesting more robust healing in those groups.
- Postoperative complications were linked to lower TPLO mRUST scores, indicating impaired healing.
- Medial cortex was excluded from scoring due to plate obstruction, validating use of only 3 cortices for scoring.
- The TPLO mRUST system may standardize healing assessment, reducing subjective bias across specialties.

In Dobberstein 2024 et al., on liver biopsy forceps, what was concluded about diagnostic suitability of 3 mm samples?
🔍 Key Findings Summary
- Subjects: 12 healthy colony cats, 68 total liver samples collected via laparoscopy
- Biopsy instruments: 3 mm vs 5 mm Storz Blakesley cup forceps
- Techniques: Twist (T), Pull (P), Twist + Pull (TP)
- Results:
- 5 mm forceps yielded significantly more hepatic lobules (mean 12.4 vs 4.9), portal triads (29.6 vs 19.0), weight, and histologic area (p < .01)
- T and P techniques yielded more portal triads and lobules than TP (p = .003 and p = .015)
- TP technique resulted in greater tissue crush vs T (p = .01)
- Good diagnostic agreement between 3 mm and 5 mm samples only with TP (κ = 0.75)
- All samples were of sufficient diagnostic quality, despite size or technique
- Clinical implication: Both 3 mm and 5 mm forceps are viable; further studies are needed to confirm diagnostic accuracy of 3 mm samples

In Radke 2022 et al., on outcome measure validation, what was the COSMIN justification for not assessing internal consistency in the LOAD instrument?
🔍 Key Findings
- CBPI, COI, and LOAD are recommended for assessing canine osteoarthritis based on COSMIN criteria.
- COI scored highest in development rigor and evidence quality among evaluated OROMs.
- Internal consistency, reliability, and responsiveness were commonly validated, though no OROMs reported measurement error.
- LOAD was considered formative, and internal consistency assessment was deemed unnecessary.
- CBPI and COI showed sufficient internal consistency, but CBPI’s factor structure was inconsistent across studies.
- All 6 evaluated OROMs (CBPI, COI, LOAD, BHSII, HCPI, HVAS) were quick to complete (under 5 min).
- Three tools—BHSII, HCPI, HVAS—need more evidence before recommendation; only CBPI, COI, and LOAD are Category A (recommended).
- Future studies should assess interpretability, including measurement error and clinically meaningful change scores (MIC, SDC).
