Tracheal luminal diameter (TLD) was measured at the caudal cervical, thoracic inlet, and intrathoracic tracheal regions on right lateral thoracic view. The absolute and average TLDs were standardized by the manubrium length (ML), thoracic inlet distance (Ti-D), and proximal third rib width to calculate M-TI, thoracic inlet tracheal index (Ti-TI), and proximal rib3 tracheal score (PR3-TS), respectively. Correlations between averaged tracheal diameter and each of ML, Ti-D, and proximal third rib width and between M-TI and each of Ti-TI and PR3-TS were evaluated.Results: 100 healthy French (n = 34), English (n = 33), and American (n = 33) Bulldogs met the inclusion criteria. The narrowest tracheal diameter was identified at the thoracic inlet, which was significantly narrower than both the caudal cervical and intrathoracic tracheal regions. There was no significant difference between the caudal cervical and intrathoracic tracheal regions. Strong, positive, linear correlations were identified between TLD and each normalizing parameter (ie, ML, Ti-D, and PR3-TS). Weak-to-moderate correlations were identified between the 3 procedures (ie, M-TI, Ti-TI, and PR3-TS).Conclusions: M-TI could be an alternative to Ti-TI and PR3-TS for monitoring TLD in bulldogs. Therefore, future screening for tracheal hypoplasia is recommended using M-TI.Clinical relevance: Bulldogs with M-TI < 0.29 at the thoracic inlet trachea and < 0.33 at the caudal cervical and intrathoracic trachea (average M-TI < 0.32) may have tracheal hypoplasia. However, further assessments of diseased bulldogs and the repeatability of measurements are still warranted.","PeriodicalId":7754,"journal":{"name":"American journal of veterinary research","volume":" ","pages":"1-8"},"PeriodicalIF":1.3,"publicationDate":"2025-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143952690","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The thermal foot withdrawal threshold (TFWT) was determined at baseline as well as 0.5, 1.5, 3, and 6 hours postinjection. Agitation-sedation scores were also evaluated at each time point prior to delivery of thermal stimulus. The changes in TFWT compared to baseline as well as agitation-sedation scores prior to each TFWT were compared among treatments over time.Results: 1 bird died during the study for unrelated causes. Hydromorphone at both doses (1 and 2 mg/kg) had a significant difference in foot withdrawal threshold from baseline when compared to the control at the 3-hour postinjection time point. Hydromorphone at 1 mg/kg significantly decreased odds of a bird having higher agitation scores (proportional OR of increase in agitation score of 1, 0.37; 95% CI, 0.14 to 0.96).Conclusions: Hydromorphone administered IM at doses of 1 and 2 mg/kg had a small but significant thermal antinociceptive effect in cockatiels at 3 hours after drug administration. Hydromorphone at 1 mg/kg demonstrated evidence of mild sedative effects.Clinical relevance: This study provides evidence that hydromorphone may provide analgesic effects when administered to cockatiels at doses higher than those evaluated in prior studies. Further studies with other types of noxious stimuli, routes of administration, and testing time points are needed to fully evaluate the analgesic effects of hydromorphone in cockatiels.","PeriodicalId":7754,"journal":{"name":"American journal of veterinary research","volume":" ","pages":"1-6"},"PeriodicalIF":1.3,"publicationDate":"2025-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143971422","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The tested hindlimb was positioned horizontally, with the dog under general anesthesia and muscle relaxation. Unforced angle (UA; when the paw was unforced), forced angle range (FAR; when the paw was under constant pushing/pulling force), and UA range (UAR; when the forces applied to the paw had been withdrawn) of the stifle and tarsal joints were evaluated using radiographic analysis while the hip joint angle was passively adjusted from 70° to 170°. Linear regression analysis was used to assess the relationships between hip, stifle, and tarsal joint angles.Results: Significantly strong linear relationships (adjusted R2 > 0.7) were found for hip-stifle and hip-tarsal in UA, UAR, and when the paw was pushed with the hip joint angle exceeding 120° (FAR-push > 120°). The FAR of stifle and tarsal joints changed with the hip joint angle. Additionally, significantly strong linear relationships (adjusted R2 > 0.85) were found for stifle-tarsal in UA, UAR, and when a constant push force was applied on the paw (FAR-push).Conclusions: This research revealed the linear relationships between canine hindlimb joint angles in the sagittal plane under specific circumstances as well as the narrowing of the FAR of stifle and tarsal joints when hip joint angle exceeds 120°.Clinical relevance: The findings on linkage mechanism-related relationships in hindlimb joints angles from this research may contribute to a better understanding of orthopedic and rehabilitation practices.","PeriodicalId":7754,"journal":{"name":"American journal of veterinary research","volume":" ","pages":"1-10"},"PeriodicalIF":1.3,"publicationDate":"2025-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143956458","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Canine cognitive dysfunction is currently underdiagnosed due to the lack of an objective and reliable diagnostic tool, and treatment options are severely limited. Importantly, CCD shares common pathological hallmarks of human Alzheimer disease, such as β-amyloid accumulation, τ protein phosphorylation, neuronal loss, and neuroinflammation. β-Amyloid deposits in Alzheimer disease and CCD appear in 2 main forms: extracellular amyloid plaques, which disrupt synaptic function and contribute to neurotoxicity, and cerebral amyloid angiopathy, where β-amyloid accumulates in the walls of cerebral blood vessels. Cerebral amyloid angiopathy leads to vascular dysfunction, chronic hypoxia, microhemorrhages, and neuroinflammation, further exacerbating cognitive decline. Research into these shared pathologies offers potential therapeutic targets that could benefit both canine and human patients suffering from these neurodegenerative disorders. In this article, we review the latest understanding of CCD pathology and discuss new advancements in diagnostic and therapeutic options as well as the outlook of the CCD disorder.","PeriodicalId":7754,"journal":{"name":"American journal of veterinary research","volume":" ","pages":"1-8"},"PeriodicalIF":1.3,"publicationDate":"2025-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143957176","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Serial measurements of interstitial glucose with FGMS and blood glucose (BG) with a portable BG monitor (PBGM) were recorded every 10 minutes for 90 minutes. At each time point, blood was also collected for gold standard BG measurement via clinical chemistry analyzer. Analytical and clinical accuracy was determined by fulfillment of International Organization for Standardization 15197:2013 criteria.Results: For BG values < 100 mg/dL, 67.2% of PBGM measurements and 50.9% of FGMS measurements were within ± 15 mg/dL of the reference method.
