OBJECTIVE To provide updated information on the distribution of histopathologic types of primary pulmonary neoplasia in dogs and evaluate the effect of postoperative adjuvant chemotherapy in dogs with pulmonary carcinoma. ANIMALS 340 dogs. PROCEDURES Medical records of dogs that underwent lung lobectomy for removal of a primary pulmonary mass were reviewed, and histopathologic type of lesions was determined. The canine lung carcinoma stage classification system was used to determine clinical stage for dogs with pulmonary carcinoma. RESULTS Pulmonary carcinoma was the most frequently encountered tumor type (296/340 [87.1%]), followed by sarcoma (26 [7.6%]), adenoma (11 [3.2%]), and pulmonary neuroendocrine tumor (5 [1.5%]); there was also 1 plasmacytoma and 1 carcinosarcoma. Twenty (5.9%) sarcomas were classified as primary pulmonary histiocytic sarcoma. There was a significant difference in median survival time between dogs with pulmonary carcinomas (399 days), dogs with histiocytic sarcomas (300 days), and dogs with neuroendocrine tumors (498 days). When dogs with pulmonary carcinomas were grouped on the basis of clinical stage, there were no significant differences in median survival time between dogs that did and did not receive adjuvant chemotherapy. CLINICAL RELEVANCE Results indicated that pulmonary carcinoma is the most common cause of primary pulmonary neoplasia in dogs; however, nonepithelial tumors can occur. Survival times were significantly different between dogs with pulmonary carcinoma, histiocytic sarcoma, and neuroendocrine tumor, emphasizing the importance of recognizing the relative incidence of these various histologic diagnoses. The therapeutic effect of adjuvant chemotherapy in dogs with pulmonary carcinoma remains unclear and warrants further investigation.

OBJECTIVE To describe the sleep patterns, working hours, and perceptions of fatigue among veterinary house officers and to identify potential areas for targeted intervention to improve well-being. SAMPLE 303 house officers. PROCEDURES A 62-item questionnaire was generated by use of an online platform and sent to veterinary house officers at participating institutions via email. Responses were analyzed for trends and associations between variables of interest. RESULTS The mean age of respondents was 30 ± 3.7 years. Participants included 239 residents and 64 interns. House officers slept significantly less during times when they had clinical responsibilities compared to off-clinic time (6.0 hours vs 7.5 hours, respectively; P < 0.01). The majority of house officers reported working 11 to 13 hours on a typical weekday (58% [174/302]), and 32% reported clinical responsibilities 7 d/wk. Working hours were negatively related to sleep quantity (Pearson correlation coefficient, −0.54; P < 0.01), and perceived sleep quality was worse when on call (P < 0.01). The majority of house officers felt that fatigue negatively interfered with their technical skills, clinical judgment, and ability to empathize to some extent in the previous 4 weeks. CLINICAL RELEVANCE Most house officers fail to obtain sufficient sleep for optimal cognitive function and physical and mental health. Working hours and on call may be important factors contributing to the sleep patterns of veterinary house officers, and training program structure should be critically evaluated to promote protected time for sleep.

Objective: To report outcomes following surgical treatment of hepatic abscessation in dogs. Study design: Retrospective.Animals: Thirty-eight dogs. Methods: Records from 6 institutions were evaluated for dogs undergoing surgical treatment for hepatic abscessation between 2010 and 2020. Signalment, clinical signs, medical therapy, surgical treatment, and postoperative outcome was obtained from medical records. Long-term outcome was recorded when possible. Median survival time was assessed using the Kaplan-Meier productlimit method.Results: Peritoneal effusion was documented in 32/38 dogs preoperatively, with septic peritonitis confirmed in 21/23 samples. Liver lobectomy was the most common surgery (27 dogs). A single organism was cultured in 24/35 dogs, most commonly Escherichia coli. Hepatic neoplasia was identified in 11/36 dogs. Dogs were hospitalized for a median of 5 days (range, 3-17) with complications recorded in 21 dogs (regurgitation, aspiration pneumonia, and pancreatitis most commonly). Two dogs died intraoperatively, and 6 dogs died prior to discharge. Median survival time for dogs surviving to discharge was 638 days. Of these, 19 were lost to follow up a median of 301 (range, 3-1418) days postoperatively and 11 died a median of 291 (range, 7-1292) days postoperatively. No abscess recurrence was noted. Conclusion: Septic peritonitis was a common sequela to hepatic abscessation.Perioperative complications were recorded in approximately one-third of dogs. In dogs surviving the postoperative period, long-term prognosis was good.Clinical significance: Dogs treated surgically for hepatic abscessation have a high risk of perioperative complications but favorable long-term prognosis and apparent low risk of recurrence.

OBJECTIVE To describe veterinary house officers’ perceptions of dimensions of well-being during postgraduate training and to identify potential areas for targeted intervention. SAMPLE 303 house officers. PROCEDURES A 62-item questionnaire was generated by use of an online platform and sent to house officers at participating institutions in October 2020. Responses were analyzed for trends and associations between selected variables. RESULTS 239 residents, 45 rotating interns, and 19 specialty interns responded to the survey. The majority of house officers felt that their training program negatively interfered with their exercise habits, diet, and social engagement. House officers reported engaging in exercise significantly less during times of clinical responsibility, averaging 1.6 exercise sessions/wk (SD ± 0.8) on clinical duty and 2.4 exercise sessions/wk (SD ± 0.9) when not on clinical duty (P < 0.001). Ninety-four percent of respondents reported experiencing some degree of anxiety regarding their physical health, and 95% of house officers reported feeling some degree of anxiety regarding their current financial situation. Overall, 47% reported that their work-life balance was unsustainable for > 1 year; there was no association between specialty and sustainability of work-life balance. Most house officers were satisfied with their current training program, level of clinical responsibility, and mentorship. CLINICAL RELEVANCE Veterinary house officers demonstrated a poor balance between the demands of postgraduate training and maintenance of personal health. Thoughtful interventions are needed to support the well-being of veterinary house officers.
