To determine whether jejunal serosal patches could securely seal large, open defects in duodenal segments harvested from canine cadavers and to compare intraluminal pressures at which leakage first occurred and maximal intraluminal pressures for repaired duodenal segments between 2 suture patterns.

Duodenal and jejunal segments from 9 canine cadavers.

20 constructs were created through repair of large, open duodenal defects with circumferential suturing of an intact jejunal segment (jejunal serosal patch). Constructs were randomly assigned to have the serosal patch anastomosed to the duodenal segment by a simple continuous or simple interrupted suture pattern. The pressure at which the first leakage was observed and the maximum pressure obtained during testing were recorded and compared between suture patterns.

Initial leakage pressure was significantly higher with the simple interrupted pattern (mean ± SD, 68.89 ± 5.62 mm Hg), compared with the simple continuous pattern (59.8 ± 20.03 mm Hg). Maximum intraluminal pressures did not significantly differ between the simple interrupted (91 ± 8.27 mm Hg) and simple continuous patterns (90.7 ± 16.91 mm Hg). All constructs, regardless of suture pattern, withstood supraphysiologic pressures.

Jejunal serosal patches adequately sealed large, open duodenal defects and prevented leakage in these constructs. Constructs with simple continuous or simple interrupted suture patterns withstood physiologic and supraphysiologic intraluminal pressures, although constructs with a simple interrupted suture pattern initially leaked at higher pressures.

To determine whether blood taurine concentrations in dogs with exocrine pancreatic insufficiency (EPI) were lower than the reference interval (200 to 350 nmol/mL) or the cutoff used to indicate taurine deficiency (< 150 nmol/mL).

18 dogs with clinical or presumptive subclinical EPI with residual blood samples available for taurine concentration analysis.

Dogs were classified as having clinical EPI if they had a serum trypsin-like immunoreactivity concentration of < 2.0 μg/L and presumptive subclinical EPI if they had a concentration of 2.0 to 5.0 μg/L. Archived, frozen blood samples stored in EDTA were submitted for measurement of taurine concentration with an automated high-performance liquid chromatography amino acid analyzer. Medical record data were examined for associations with blood taurine concentration.

None of the 18 dogs had a blood taurine concentration < 150 nmol/mL. Two dogs had a concentration < 200 nmol/mL. No clinical signs, physical examination findings, or serum biochemical abnormalities were associated with blood taurine concentration. Eleven of the 17 dogs for which diet histories were available were not receiving a diet that met recommendations of the World Small Animal Veterinary Association Global Nutrition Committee.

A low blood taurine concentration was noted in a small subset of dogs with EPI. Additional research is needed to determine whether EPI was the primary cause of this low concentration. Findings suggested the importance of obtaining complete diet histories and ensuring dietary requirements are sufficiently met in dogs with EPI. Phenazine methosulfate

To evaluate intrasession and intersession repeatability of measurements for temporospatial and kinetic variables obtained with a pressure-sensitive treadmill designed for gait analysis of dogs.

16 client-owned dogs.

The influence of treadmill speed on accuracy of ground reaction force (GRF) measurements was assessed by simulated gait analysis at 0 to 7.5 km/h with a custom test device. link2 A similar test was performed with 1 client-owned dog ambulating on the treadmill at 5 speeds (3 to 7 km/h) for GRF calculations. Fifteen client-owned dogs were then walked on the treadmill at 3 km/h for collection of temporospatial and kinetic data. Intrasession repeatability was determined by comparing 2 sets of measurements obtained ≤ 2 hours apart. Intersession repeatability was determined by comparing the first set of these measurements with those for a second session ≥ 4 days later. Intraclass correlation coefficients (ICCs; consistency test) and difference ratios were calculated to assess repeatability.

Increases in treadmill speed yielded a mean 9.1% decrease in weight-normalized force data at belt speeds of up to 7.5 km/h for the test device, compared with the value when the treadmill belt was stationary. Results were similar for the dog at increasing treadmill speeds (mean decrease, 12.4%). For temporospatial data, intrasession ICCs were > 0.9 and intersession ICCs ranged from 0.75 to 0.9; for GRFs, intrasession and intersession ICCs ranged from 0.68 to 0.97 and from 0.35 to 0.78, respectively.

Repeatability of temporospatial data for healthy dogs was good to excellent; results for kinetic data varied. Further research is needed to investigate use of this system for gait analysis with larger samples of dogs and dogs with lameness.

To determine whether a customized unilateral intervertebral anchored fusion device combined with (vs without) an intervertebral spacer would increase the stability of the L1-L2 motion segment following complete intervertebral diskectomy in canine cadaveric specimens.

Vertebral columns from T13 through L3 harvested from 16 skeletally mature Beagles without thoracolumbar disease.

Complete diskectomy of the L1-2 disk was performed in each specimen. Unilateral stabilization of the L1-L2 motion segment was performed with the first of 2 implants a unilateral intervertebral anchored fusion device that consisted of a locking compression plate with or without an intervertebral spacer. The resulting construct was biomechanically tested; then, the first implant was removed, and the second implant was applied to the contralateral side and tested. Range of motion in flexion and extension, lateral bending, and torsion was compared among intact specimens (prior to diskectomy) and constructs.

Compared with intact specimens, constructs stabilized with either implant were as stable in flexion and extension, significantly more stable in lateral bending, and significantly less stable in axial rotation. Constructs stabilized with the fusion device plus intervertebral spacer were significantly stiffer in lateral bending than those stabilized with the fusion device alone. No significant differences in flexion and extension and rotation were noted between implants.

Findings did not support the use of this customized unilateral intervertebral anchored fusion device with an intervertebral spacer to improve unilateral stabilization of the L1-L2 motion segment after complete L1-2 diskectomy in dogs.

To evaluate a contrast medium that could be used for radiographic and ultrasonographic assessment of the small intestine in dogs.

8 healthy adult Beagles.

Carboxymethylcellulose (CMC; 0.5% solution) was combined with iohexol (300 mg of iodine/mL) to yield modified contrast medium (MCM). Dogs were orally administered the first of 3 MCMs (10 mL/kg [9.5 mL of CMC/kg plus 0.5 mL of iohexol/kg]). Radiographic and ultrasonographic assessment of the small intestine followed 10 minutes after administration and every 10 minutes thereafter, until MCM was seen within the ascending colon. Minimally, 1 week elapsed between dosing of subsequent MCMs (10 mL/kg [9 mL of CMC/kg plus 1 mL of iohexol/kg and 8.5 mL of CMC/kg plus 1.5 mL of iohexol/kg]) and repeated radiography and ultrasonography.

Radiographic contrast enhancement of the small intestine was best with MCM that combined 8.5 mL of CMC/kg and 1.5 mL of iohexol/kg. Mean small intestinal transit time for all MCMs was 86 minutes. All MCMs did not interfere with ultrasonographic assessment of the small intestine and may have improved visualization of the far-field small intestinal walls.

An MCM that combined 8.5 mL of 0.5% CMC/kg and 1.5 mL of iohexol/kg could be an alternative to barium or iohexol alone for contrast small intestinal radiography in dogs, especially when abdominal ultrasonography is to follow contrast radiography.

Older adults are closely connected to their neighborhoods and they spend more time there than younger adults. Because their mobility is often impeded by diminished health and functioning, access to neighborhood health and social services is essential for their well-being. This article examines whether geographic proximity to these types of neighborhood resources is associated with depression among older adults in South Korea.

Data are from
which sampled 1,455 community-dwelling individuals ages 60 and older in South Korea. The Patient Health Questionnaire-9 (PHQ-9) was used to assess depression, the outcome. We measured geographic proximity to neighborhood destinations, which included the time it takes the respondent to go to the grocery store, hospital, government office, senior center, social service center, and bus stop. We conducted latent profile analyses (LPA) with a distal outcome using the BCH method to determine whether geographic proximity to neighborhood resources is associated with depression.

The LPA identified three distinct subgroups of geographic proximity to neighborhood resources
(10%),
(41%), and
(49%). link3 Low Access (
 = 3.71,
 < .001) and Moderate Access (
 = 3.00,
< .001) groups had higher levels of depression compared to those in the High Access group.

Our findings suggest that access to essential services in one's neighborhood is associated with lower levels of depression, which supports existing evidence that age-friendly community initiatives are important to older adults' psychological well-being.
