  Objective: To describe the syndrome of suspected gastroduodenal ulceration/erosion (GUE) in dogs with intrahepatic portosystemic shunts (IHPSS) before and after percutaneous transvenous coil embolization (PTCE). Methods: In a multi-institutional, retrospective case series, medical records from 7 specialty hospitals were reviewed to identify dogs with IHPSS diagnosed with suspected GUE prior to or following PTCE from July 31, 2013, to August 1, 2023. Eleven client-owned dogs were divided into 2 groups based on ulcer grade as determined by the Veterinary Cooperative Oncology Group-Common Terminology Criteria for Adverse Events guidelines for gastric ulceration. Factors were evaluated for association with GUE severity. Results: At the time of GUE diagnosis, the median age and weight of dogs were 20 months (range, 2 to 48 months) and 20.9 kg (range, 6.6 to 36.5 kg). Five and 6 dogs were diagnosed with suspected GUE before and after PTCE, respectively. High- and low-grade suspected GUEs were diagnosed in 6 and 5 dogs, respectively. Common clinical signs included vomiting with or without hematemesis (n = 8), lethargy (7), and inappetence (6). Dogs were receiving omeprazole (n = 2) and a steroid (1) or NSAID (5) at the time of suspected GUE diagnosis. No dogs receiving an NSAID were concurrently being treated with omeprazole. No factors evaluated were significantly associated with increased severity of suspected GUE. Conclusions: Dogs with IHPSS experience GUE despite prophylactic medical management and treatment via PTCE. Clinical Relevance: Cautious use of medications associated with GUE should be considered in dogs with IHPSS. The pathophysiology of GUE in dogs with IHPSS remains incompletely understood.

• Outcome in 38 dogs surgically treated for hepatic abscessation

  Veterinary Surgery · 2022-11-22 · 4 citations

  article

  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 product-limit 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 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 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.

  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.

• Dysponesis Awareness Training: Surface Electromyographic Training for Increased Awareness and Facilitated Neck Muscle Relaxation

  Biofeedback · 2012-12-01

  articleSenior author

  This study investigated a simple biofeedback-assisted training protocol for increasing somatic awareness as well as reducing dyponesis. Twelve normal, healthy volunteers with no known musculoskeletal impairments (mean age of 23.8 years) were trained to increase awareness of “wasted effort” in the neck muscles during a simple bending task. Surface electromyography (sEMG) signals were recorded from the midcervical paraspinal muscles (C-5) while the subject performed a forward fold, also described as a “toe touch” movement. The quantitative measures of sEMG activity were compared to a subjective measure of neck muscle tension. During the pretraining measurements, 11 of 12 participants reported no subjective awareness of increased neck muscle tension while bending in a forward fold “toe touch” position. After approximately 10 minutes of “dysponesis awareness training,” all participants had measurable reductions in neck muscle tension, as well as reductions in the subjective sense of tension while performing the forward fold exercise, as compared to pretraining. The 11 participants who increased their self-awareness following training reported not only feeling decreased neck muscle tension but also increased general relaxation levels. The findings suggest that most individuals may be unaware of increased muscle tension during simple activities such as a forward bend, yet may rapidly learn how to reduce dysponesis, such as unnecessary neck muscle overexertion during a forward bend. Furthermore, sEMG dysponesis awareness training could be adapted to rapidly train individuals such as athletes to reduce unnecessary muscle use.
