Three-dimensional kinematic evaluation of Tightrope CCL in a canine in vitro cranial cruciate deficient stifle model 全文
2019

The impact of surgical correction of cranial cruciate ligament-deficient stifles (CCDS) on the 3-dimensional (3D) kinematics of the canine stifle has been sparsely evaluated. Tightrope (TR) cranial cruciate ligament (CCL) has been proposed to restore baseline 3D kinematics in CCDS by using isometric points. We hypothesized that TR would restore baseline 3D kinematics of the stifle in our model. Ten pelvic limbs were used with a previously validated apparatus. Three experimental conditions were evaluated: i) intact stifle, ii) cranial cruciate ligament transection (CCLt), and iii) CCLt stabilized with TR; kinematic data was recorded. Tightrope CCL in CCDS did not limit sagittal flexion. Tightrope CCL neutralized internal rotation without restoring baseline curves, but it did not restore abduction, nor did it neutralize or restore cranial translation, but it did restore latero-medial and proximo-distal translations. In our model, TR without pre-conditioning of the FiberTape strands did not restore baseline stifle 3D kinematics and residual cranial translation could result in frequent meniscal tears.

OBJECTIVE To test the hypothesis that once-daily oral administration of atenolol would attenuate the heart rate response to isoproterenol for 24 hours. ANIMALS 20 healthy dogs. PROCEDURES A double-blind randomized placebo-controlled crossover study was conducted. Dogs were assigned to receive atenolol (1 mg/kg, PO, q 24 h) or a placebo for 5 to 7 days. After a washout period of 7 days, dogs then received the other treatment. Heart rate at rest (HRr) and heart rate induced by administration of isoproterenol (HRi) as a constant rate infusion (0.2 μg/kg/min for 5 to 7 minutes) were obtained by use of ECG 0, 0.25, 3, 6, 12, 18, and 24 hours after administration of the final dose of atenolol or the placebo. A mixed-model ANOVA was used to evaluate effects of treatment, time after drug or placebo administration, treatment-by-time interaction, period, and sequence on HRr and HRi. RESULTS Effects of sequence or period were not detected. There was a significant effect of treatment and the treatment-by-time interaction on HRi. Atenolol significantly attenuated HRi for 24 hours but did so maximally at 3 hours (least squares mean ± SE, 146 ± 5 beats/min and 208 ± 5 beats/min for atenolol and placebo, respectively). The effect at 24 hours was small (193 ± 5 beats/min and 206 ± 5 beats/min for atenolol and placebo, respectively). Atenolol had a small but significant effect on HRr. CONCLUSIONS AND CLINICAL RELEVANCE This study of healthy dogs receiving atenolol supported a recommendation for a dosing interval < 24 hours.

OBJECTIVE To assess the feasibility of esophageal insufflation CT (EICT) for evaluation of the esophagus in dogs. ANIMALS 7 clinically normal adult Beagles. PROCEDURES Each dog was anesthetized twice with 1 week between anesthesia sessions. Dogs were positioned in sternal recumbency during all CT scans. During the first anesthesia session, a CT scan was performed before the esophagus was insufflated (insufflation pressure, 0 mm Hg) and unenhanced and contrast-enhanced EICT scans were performed after CO(2) was insufflated into the esophageal lumen to achieve a pressure of 5 mm Hg. For the contrast-enhanced scan, each dog received iohexol (600 mg/kg, IV), and the scan was performed 30 seconds later. During the second anesthesia session, unenhanced and contrast-enhanced EICT scans were performed in the same manner except the insufflation pressure achieved was 10 mm Hg. The esophageal luminal cross-sectional area and wall thickness were measured at each of 5 segments, and mean values were compared among the 3 insufflation pressures and between unenhanced and contrast-enhanced images. RESULTS Mean esophageal luminal cross-sectional area increased and esophageal wall thickness decreased as insufflation pressure increased. Measurements did not differ significantly between unenhanced and contrast-enhanced images. The stomach became distended with CO(2) at an insufflation pressure of 10 mm Hg but not at 5 mm Hg. No adverse effects were observed. CONCLUSIONS AND CLINICAL RELEVANCE Results suggested EICT was feasible for esophageal evaluation in dogs. Further research is necessary to determine the optimal insufflation pressure for the procedure and its diagnostic efficacy in diseased patients.

Varner, Kelley M. | Hopster, Klaus | Driessen, Bernd
OBJECTIVE To assess effects of nitrogen and helium on efficacy of an alveolar recruitment maneuver (ARM) for improving pulmonary mechanics and oxygen exchange in anesthetized horses. ANIMALS 6 healthy adult horses. PROCEDURES Horses were anesthetized twice in a randomized crossover study. Isoflurane-anesthetized horses in dorsal recumbency were ventilated with 30% oxygen and 70% nitrogen (treatment N) or heliox (30% oxygen and 70% helium; treatment H) as carrier gas. After 60 minutes, an ARM was performed. Optimal positive end-expiratory pressure was identified and maintained for 120 minutes. Throughout the experiment, arterial blood pressures, heart rate, peak inspiratory pressure, dynamic compliance (C(dyn)), and Pao(2) were measured. Variables were compared with baseline values and between treatments by use of an ANOVA. RESULTS The ARM resulted in significant increases in Pao(2) and C(dyn) and decreases in the alveolar-arterial gradient in the partial pressure of oxygen in all horses. After the ARM and during the subsequent 120-minute phase, mean values were significantly lower for treatment N than treatment H for Pao2 and C(dyn). Optimal positive end-expiratory pressure was consistently 15 cm H(2)O for treatment N, but it was 10 cm H(2)O (4 horses) and 15 cm H(2)O (2 horses) for treatment H.

Elrod, S. M. | Hofmeister, E. H.
The objective of this study was to assess veterinarians' understanding of nutraceutical use in humans and companion animals and their motivation and circumstances for recommending nutraceuticals to clients. We administered a cross-sectional survey to veterinarians attending continuing education sessions at the University of Georgia (USA) College of Veterinary Medicine from 2012 to 2015 (N = 126). Information regarding veterinarians' age, year of graduation, practice focus, and typical approaches to nutraceutical use was compiled from the returned surveys. The results indicated that veterinarians are more familiar with nutraceutical use in animals than in humans and primarily recommend nutraceuticals to their clients for preventative purposes and/or due to client interest. Veterinarians believed that nutraceuticals were most useful for osteoarthritis and therefore use omega-3 fatty acid and glucosamine/chondroitin products more often than other products for both their patients and their own pets. Safety and efficacy were the most important considerations when deciding which nutraceuticals to recommend to clients. The survey results show that veterinarians are familiar with nutraceuticals and open to their use in patients when they perceive these products to be safe and efficacious.

Postpartum an estrus in cows is regarded as one of the most important causes of functional infertility after parturition during reproductive lifespan. Therefor the present study was conducted to induce fertile estrus in anestrus cows which suffered from inactive ovaries (IO) or persistent corpus luteum(PCL) after parturition. The results of current study showed the efficiency of using GnRH or FSH as a hormonal medication to induce fertile estrus with pregnancy which reach 71.42 and 72.22 % respectively, as well as decreasing the length of days open (DO) to lesser than 150 day in both programs in 70.00 and 76.92 % respectively from induced estrus cows. Also the results revealed that the role of PGF2α in induction of fertile estrus with 83.33% of pregnancy in cows which suffered from postpartum PCL and decrease the length of DO in 80.00% from induced estrus cows. The present study improved the efficacy of uterine massage (UM) through rectal palpation to treat cases of PCL in postpartum anestrus cows with 71.42% of pregnancy, and its effect to decrease the length of DO in 60.00% from induced estrus cows.
