🔍 Key Findings

• Tracheal anastomoses in immature dogs failed at significantly lower distraction forces (44.91 ± 59.03 N) than in adults (149.31 ± 45.36 N; _P_ = .007).
• Immature tracheae tolerated significantly more elongation before failure (39.75 ± 5.45%) than adult tracheae (30.57 ± 7.19%; _P_ = .0012).
• All constructs failed by suture tearing through the annular ligament, primarily near the dorsal tracheal ring.
• Overlapping of tracheal ends was seen in 50% of specimens across both age groups, suggesting limitations in tissue apposition with the chosen technique.
• Simple continuous pattern using 2-0 polypropylene was used; this pattern provides superior tensile strength compared to simple interrupted, but apposition may be suboptimal.
• Tracheal elasticity in immature dogs may allow longer resections, but the lower tensile strength necessitates reinforcement.
• Annular ligament-cartilage technique with 4-mm suture spacing showed variable results; smaller bites and nylon suture may improve outcomes.
• Ex vivo setup using frozen-thawed tracheae is a limitation, but prior studies support comparability with fresh tissue.

🔍 Key Findings

• Zurich mini-cementless THA was successful in 9/10 hips in dogs <4 kg, with no lameness at 52 weeks in completed cases.
• Helsinki Chronic Pain Index significantly improved from a mean of 19.8 to 2.3 at 52 weeks (p = 0.0141).
• Fluoroscopy improved implant positioning, especially in LCPD and HD cases, aiding in accurate reaming and alignment.
• Intraoperative complications occurred in 2/10 cases, including acetabular fractures; one case required discontinuation.
• Prophylactic bicortical screws and reinforcement plates were used in cases with rotational instability or cortical compromise and were effective in preventing loosening/fractures.
• Medial patellar luxation improved postoperatively in one dog, though recurrence was noted later without surgical correction.
• No stem or implant loosening or fracture occurred over a mean follow-up of 24.4 months.
• CT is recommended in preoperative planning, particularly in luxoid hip dysplasia cases with uncertain bone stock.

🔍 Key Findings

• Postoperative Protein C (PC) activity increased in 78.7% of dogs, and was significantly higher in dogs with excellent clinical outcomes.
• Complete acute shunt occlusion resulted in higher postoperative PC activity (96.3%) and better ultimate clinical outcomes than incomplete occlusion.
• Preoperative PC was not predictive of clinical status, but postoperative PC was associated with improved outcomes.
• Standard biochemical markers (HCT, MCV, ALB, BUN) also improved postoperatively, especially in dogs with excellent clinical outcomes.
• Dogs requiring a second procedure had significantly lower postoperative PC (43.5%) than those not requiring further intervention (78.5%).
• Repeat procedures improved PC and BUN values, with PC increasing significantly after second intervention (to 69.8%).
• PC normalization (within reference interval) occurred in 87.5% of dogs with excellent clinical status, compared to only 12.5% in those with poor status.
• Clinical outcome classification (excellent/fair/poor) correlated with biochemical normalization and lack of need for diet/medications.

🔍 Key Findings

• Dorsoventral radiographs artificially increase Norberg angle values by 3.2–5.8% and should be excluded.
• Lateral pelvic tilt >2° causes asymmetric changes in Norberg angle; >3° results in significant side-specific changes.
• Cranioventral-to-caudodorsal tilt >10° results in obvious radiographic tilt, but changes Norberg angle by only ~2%.
• Tilted but subjectively acceptable images have minor impact and may still be usable for screening.
• Norberg angle readings differed consistently between left/right hips — possibly due to operator handedness.

🔍 Key Findings

• Short-term resolution of hypercalcemia occurred in 97.8% (44/45) of dogs.
• Long-term cure rate was 93.3%, comparable to traditional bilateral neck exploration.
• Postoperative hypocalcemia was observed in only 15.6%, which is lower than traditional approaches (36–63.8%).
• Permanent hypocalcemia occurred in 4.4%, requiring lifelong calcitriol supplementation.
• Minimally invasive approach had median surgical times of 26 min (unilateral) and 45.5 min (bilateral).
• Most lesions were adenomas (54.8%), followed by hyperplasia (27.4%) and carcinomas (3.2%).
• Ultrasound identified 98.4% (61/62) of abnormal glands, supporting it as the preferred imaging modality.
• One death due to non-compliance with calcitriol, emphasizing importance of postoperative management.

🔍 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.

🔍 Key Findings

• Medial meniscus injury (MMI) occurred in 36.3% of stifles with CrCLR in toy breed dogs (<5 kg)
• Complete CrCLR was significantly associated with MMI (15.3% of complete vs. 3.4% of partial)
• Severe lameness (grade 3) increased the likelihood of MMI compared to mild lameness (grade 1)
• Higher body weight, even within the toy breed range, was positively associated with MMI
• Yorkshire Terriers had the highest MMI incidence (55.6%), but this was not a significant independent factor due to multicollinearity
• Arthroscopy identified more meniscal damage (including small radial tears and bucket-handle lesions) than gross examination might detect
• MMI was classified as mild (radial tear) or severe (bucket-handle or flap) with implications for partial meniscectomy
• Arthroscopy was used in all cases, underscoring its utility in small-breed stifle assessment

🔍 Key Findings

Mortality rate: 36% (12/33)
Cholecystectomy performed: 94% of dogs (31/33)
New significant prognostic factors for survival:

• Hyperbilirubinemia (p = .049) — threshold = 60.5 μmol/L
• Use of vasopressors (p = .002)
• Renal dysfunction postoperatively (p = .008)
• Number of postoperative complications (p = .005)

Multivariate model: Total bilirubin and number of complications best predicted survival
Septic vs nonseptic effusion: No significant difference in survival
Diagnostic imaging: Ultrasound sensitivity for extrahepatic biliary rupture = 38%
Most cultured pathogen: E. coli (80% of septic cases)

🔍 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.

🔍 Key Findings

• Remote respiratory function grading (RFG) had poor to moderate reliability compared to in-person assessment.
• Expert graders had higher agreement with in-person scores than novices (Cohen’s kappa 0.37–0.48 vs. 0.21–0.47).
• Interobserver agreement was moderate among experts (Fleiss’ kappa = 0.59) and poor among novices (Fleiss’ kappa = 0.39).
• Remote recordings suffered from background noise, short clip durations, and technical limitations of electronic stethoscope recordings.
• Final RFG scores were based on the highest grade across categories (respiratory noise, inspiratory effort, dyspnea/cyanosis/syncope).
• Clinical impact: Only in-person grading reliably supports decisions for surgical intervention or breeding restrictions.
