OBJECTIVE: To evaluate the prognostic value of measuring heart rate variability (HRV) in horses with colic at the time of admission to a referral hospital. ANIMALS: 51 horses > 1 year of age with colic (41 that survived [survivors] and 10 that died or were euthanized [nonsurvivors]). PROCEDURES: HRV was recorded within 1 hour after admission by use of heart rate sensors with horses restrained in stocks. A 5-minute recording period was analyzed to obtain HRV measurements (eg, SD of R-R intervals [SDRR], root mean square of successive differences between R-R intervals [RMSSD], and geometric SDs determined from Poincaré plots [SD1 and SD2])...

OBJECTIVE: To examine the effects of imidazoline and nonimidazoline α-adrenergic agents on aggregation of feline platelets. SAMPLE: Blood samples from 12 healthy adult cats. PROCEDURES: In 7 experiments, the effects of 23 imidazoline and nonimidazoline α-adrenoceptor agonists or antagonists on aggregation and antiaggregation of feline platelets were determined via a turbidimetric method. Collagen and ADP were used to initiate aggregation...

OBJECTIVE: To determine the effects of 2 augmentation techniques on the mechanical properties of titanium cannulated bone screws. SAMPLE: 33 titanium cannulated bone screws (outer diameter, 6.5 mm; guide channel diameter, 3.6 mm). PROCEDURES: 11 screws were allocated to each of 3 groups. The guide channel of each screw was filled with polymethyl methacrylate bone cement alone (OCS group) or in combination with a 3.2-mm-diameter orthopedic pin (PCS group) or remained unmodified (control group) before mechanical testing...

OBJECTIVE: To evaluate the usefulness of intestinal biomarkers in determining the presence of intestinal epithelial damage in neonatal calves with diarrhea caused by 4 etiologic agents. ANIMALS: 40 neonatal calves that were healthy (n = 10) or had diarrhea (30). PROCEDURES: The study was a cross-sectional study. Results of hematologic analyses and serum concentrations of intestinal fatty acid-binding protein (I-FABP), liver fatty acid-binding protein (L-FABP), trefoil factor 3 (TFF-3), Claudin-3 (CLDN-3), γ-enteric smooth muscle actin (ACTG2), intestinal alkaline phosphatase (IAP), interleukin-8 (IL-8), platelet-activating factor (PAF), and leptin (LP) were compared among calves grouped according to whether they were healthy (control group; G-1) or had diarrhea caused by K99 Escherichia coli (G-2; n = 10), bovine rota- or coronavirus (G-3; 5 each), or Cryptosporidium spp (G-4; 10)...

OBJECTIVE: To investigate the diagnostic usefulness of split-bolus CT enterography in dogs. ANIMALS: 6 healthy Beagles. PROCEDURES: CT enterography was performed in all dogs in a nonrandomized crossover study design involving 3 techniques: a dual-phase technique and 2 techniques involving splitting of the administered contrast agent dose (ie, split technique and split-bolus tracking technique). For the 2 techniques involving dose splitting (ie, split CT enterography), contrast agent was injected twice, with the first injection consisting of 60% of the total dose, followed by injection of the remaining 40%...

SAMPLE: 18 pairs (36 specimens) of third metacarpal bones from euthanized horses with no known metacarpal disease. PROCEDURES: In each bone, an investigator drilled 3 holes for placement of a 6.3-mm cylindrical transfixation pin, a 6.3-mm tapered pin using a prototype tapered tap, and a 6...

OBJECTIVE: To assess effects of basal-bolus insulin treatment (BBIT) with lispro and neutral protamine Hagedorn (NPH) insulins, compared with NPH insulin alone, on serum fructosamine concentration (SFC) and postprandial blood glucose concentration (BGC) in dogs with clinically well-controlled diabetes mellitus and postprandial hyperglycemia fed a high insoluble fiber-content diet. ANIMALS: 6 client-owned dogs with diabetes mellitus. PROCEDURES: Blood samples were collected for BGC and SFC measurement in hospitalized dogs just before feeding and routine SC NPH insulin administration (time 0); samples were collected for BGC measurement every 30 minutes for 2 hours, then every 2 hours for up to 10 additional hours...

OBJECTIVE: To compare left atrial volume (LAV) and right atrial volume (RAV) determined by 2-D and 3-D echocardiographic methods with the LAV and RAV determined by ECG-gated multidetector CT (MDCT) for healthy dogs. ANIMALS: 11 healthy purpose-bred young adult hound-type dogs. PROCEDURES: Each dog was anesthetized and underwent MDCT and a complete echocardiographic examination. Modality-specific software was used to measure the respective atrial volumes at ventricular end systole, and LAV and RAV measurements were subsequently indexed to body weight and compared among imaging modalities...
