The objective of this study is to report the clinical features, diagnosis, surgical treatment, and outcomes of dogs with epiglottic conditions treated using diode laser epiglottidectomy (DLE). This was a single-institution observational prospective study. Thirty-five dogs diagnosed with epiglottic disease underwent DLE. In all cases, an epiglottic disease was documented with combined laryngoscopic examination, when needed, fluoroscopy, computed tomography (CT) scan, and biopsy. Sub-total (SDLE) and total (TDLE) diode laser epiglottidectomy was performed under endoscopic guidance according to the diagnosis. Follow-up was performed by a re-examination visit and endoscopy, and telephone follow-up with the owner. The most common epiglottic disorder was epiglottic retroversion (ER) (57.1 %). SDLE was performed in 32/35 (91.4 %) dogs, while 3/35 (8.6 %) dogs underwent TDLE. Intraoperative complications occurred in 11.4 % surgeries, primarily involving bleeding. Postsurgical complications were reported in 8.5 % cases post-SDLE and were represented by transient airway obstruction caused by local edema. Follow-up (median 18 months, minimum 3 months – maximum 21 months) consultations revealed prolonged resolution of upper airway obstruction without signs of respiratory tract compromise or dysphagia. The surgical techniques described in this study have proven to be effective and minimally invasive for the treatment of epiglottic-related airway obstruction.</div></div>","PeriodicalId":23505,"journal":{"name":"Veterinary journal","volume":"311 ","pages":"Article 106345"},"PeriodicalIF":2.3,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143788985","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A longitudinal observational study was carried out on 100 veterinary professionals from six institutions in Lahore for six months by engaging them in a structured mentorship program. The AHMF targeted key developmental areas: welfare advocacy, clinical expertise, communication, kit content and maintenance, and clinical governance. Monthly assessments were carried out using the AHMF scoring tool, and the results were analyzed using the Friedman test across these five competencies. The results showed statistically significant improvements in all aspects. The welfare advocacy score increased from 1.13 at the start to 3.62 by the end of the study, clinical expertise improved from 8.26 to 12.51 while clinical governance enhanced from 0.14 to 1.12. Communication skills and kit management also improved significantly, although at a slightly slower rate. The average total AHMF score of the participants increased from 13.14 to 22.37, thus emphasizing all-rounded improvements in veterinary practices. The outcomes suggest that formal mentoring through the AHMF significantly enhances veterinary professionals' ethical and technical competencies, particularly in resource-poor settings. AHMF is a scalable, globally adaptable model, that can improve veterinary education, practice, and animal welfare, particularly in low and middle-income countries. This pioneering research sets a benchmark for professional development and offers a practical solution to elevate animal welfare and clinical expertise globally.</div></div>","PeriodicalId":23505,"journal":{"name":"Veterinary journal","volume":"311 ","pages":"Article 106348"},"PeriodicalIF":2.3,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143789041","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A rectal and a perivulvar swab were collected from 80 healthy bitches, half of which were housed in breeding kennels and the other half in domestic environments.

Antibiotic resistance rates, the percentage of Extended Spectrum Beta-Lactamase (ESBL)-producing <em>E.coli</em> strains, the percentage of <em>mecA</em> positive methicillin-resistant Staphylococci and of Multi-Drug Resistant (MDR) isolates were compared between breeding bitches and privately owned ones using Fisher's exact test. The percentage of resistance to the antimicrobials tested was generally higher in dogs from breeding kennels than in owned animals, with statistically significant differences in <em>E.coli</em> for cefazolin (p &lt; 0.0001), third-generation cephalosporins (p = 0.0015), tetracycline (p = 0.0079), kanamycin (p = 0.0291) and trimethoprim-sulfamethoxazole (p = 0.0007).

The pattern of antibiotic resistance, particularly to aminopenicillins but also to amoxicillin-clavulanic acid, suggests a large use of these agents. The results confirm that healthy dogs can harbour commensal bacteria that have acquired antimicrobial resistances, which may be exchanged between hosts; the potential role of the two dog typologies as reservoirs for resistance genes was demonstrated. The risk of household dogs being exposed to resistant bacteria, probably of human origin, was also observed.

However, the trends of key hormone changes during the estrous, pregnancy, and lactation periods are not well understood, and there is a lack of ultrasound-based formulas for predicting fetal development at different stages. This study aimed to elucidate the dynamic changes in key reproductive hormones and establish ultrasound-based methods to assess fetal development and predict gestational age in purebred British Shorthair cats (n=5). Plasma concentrations of estradiol (E<sub>2</sub>), progesterone (P<sub>4</sub>), follicle-stimulating hormone (FSH), luteinizing hormone (LH), and melatonin (MT) were analyzed across estrous, pregnancy, and lactation. The correlations between ultrasound measurements and gestational age were analyzed using Pearson's correlation coefficient. Additionally, we used ultrasound measurements to develop methods for assessing fetal development and predicting gestational age. E<sub>2</sub> peaked at 230.8 used ultpmol/L during estrus and showed a secondary peak around day 15 post-mating; P4 remained at baseline (1.02 ± 0.58 nmol/L) during estrus but reached a peak of 123.11.11 daynmol/L around day 21 of pregnancy. FSH and LH showed characteristic fluctuations, with peak concentrations of 29.2 ± 6.19 IU/L and 43.3 ± 12.23ng/L, respectively. Gestational age correlated strongly with ultrasound measurements of fetal length (r > 0.90), biparietal diameter, and femur length (all P < 0.001). Regression equations for these parameters were developed, enabling precise gestational age predictions. Notably, fetal heart rate followed a characteristic pattern, stabilizing at ~250 bpm mid-pregnancy before declining near parturition. These findings advance the understanding of feline reproductive physiology, providing critical benchmarks for reproductive monitoring, improved veterinary care, and breeding management.</p>","PeriodicalId":23505,"journal":{"name":"Veterinary journal","volume":" ","pages":"106321"},"PeriodicalIF":2.3,"publicationDate":"2025-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143650975","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
