Outcomes and prognostic variables associated with primary abdominal visceral soft tissue sarcomas in dogs: A Veterinary Society of Surgical Oncology retrospective study.

Primary abdominal visceral soft tissue sarcomas (STSs) are rare tumours in dogs with little information available on outcomes. The goal of this retrospective, multi-institutional study was to describe the common tumour types, location and prognostic factors associated with primary abdominal visceral STSs. Medical records were searched for dogs with primary abdominal visceral STSs at six institutions and were retrospectively reviewed. Tumours were graded using the previously described grading scheme for STSs of the skin and subcutis when information in the histopathology report contained adequate details. Forty-two dogs were included in the study. Five dogs had grade I tumours, 11 had grade II and 15 had grade III tumours. The most common tumour type was leiomyosarcoma (38.1%). The most common tumour locations were the spleen (47.6%) and small intestine (23.8%). The local recurrence rate was low (4.7%). Metastasis was present at the time of surgery in 23.8%, and the overall metastatic rate was 40.4%. Mitotic index of ≥9 was associated with significantly shorter survival time (MST 269 days) compared with a mitotic index of <9 (MST not reached). The MST for grade I STSs was not reached, was 589 days for grade II and 158 days for grade III. Dogs with grade III tumours were more likely to develop metastatic disease. Neither location of the primary tumour nor the histologic subtype was associated with survival time. Histologic grading of abdominal visceral STSs using the previously described scheme is prognostic and should be provided on histopathology reports.

Outcomes and prognostic variables associated with central division hepatic lobectomies: 61 dogs.

OBJECTIVE: To determine the outcome and prognostic variables associated with long-term survival and complications in dogs undergoing hepatic lobectomy of the central division. STUDY DESIGN: Multi-institutional retrospective case series. ANIMALS: Sixty-one client-owned dogs with central division masses. METHODS: Medical records of dogs undergoing hepatic lobectomy of the central division from January 1, 2000 to January 1, 2015 were reviewed for signalment, clinical signs, preoperative staging, preoperative cytology or biopsy results, date of procedure, location of mass, surgical technique, whether cholecystectomy or cholecystopexy was performed, complications, histopathologic diagnosis and margin evaluation, date of local recurrence or detection of metastatic disease, and survival. RESULTS: Hilar resection was associated with increased intraoperative and postoperative complications. Intraoperative complications occurred in 29 dogs, with 20 dogs experiencing intraoperative hemorrhage. Nineteen dogs required transfusions. Immediate postoperative complications occurred in 20 dogs. Perioperative mortality rate was 11%, and 2-week mortality rate was 14.7%. The median survival time for dogs with hepatocellular carcinoma (HCC) was not reached. The 1- and 3-year censored survival rates for dogs with HCC was 82.1% and 82.1%, respectively. Margin status did not impact survival time. CONCLUSION: Hepatic lobectomy of the central division was associated with hemorrhage in approximately 33% of dogs, but there was a relatively low perioperative mortality rate. Hepatic lobectomy for HCC resulted in long-term survival, regardless of margin status. CLINICAL SIGNIFICANCE: Surgeons should anticipate the requirement for blood products in dogs that may require hepatic lobectomy of the central division. Long-term survival can be expected after surgical treatment of HCC, regardless of margin status.

Relation of Opportunity to Learn Advanced Math to the Educational Attainment of Rural Youth.

Our study examined the relation of advanced math course-taking to the educational attainment of rural youth. We used data from the Educational Longitudinal Study of 2002. Regression analyses demonstrated that when previous math achievement was accounted for rural students take advanced math at a significantly lower rate than urban students. Compared to urban students, rural students have less change in their math achievement from 10th to 12th grade, are less likely to be enrolled in a 4-year college two years postsecondary, and these differences are explained by advanced math course-taking. Limitations, implications, and future research directions are discussed.

Subscription to the Surgical Council on Resident Education web portal and qualifying examination performance.

BACKGROUND: The Surgical Council on Resident Education (SCORE) curriculum for general surgery was developed to guide surgery residents in the acquisition of knowledge for patient care. We hypothesized that residents in programs that subscribed to the SCORE web portal would perform better on the American Board of Surgery (ABS) Surgery Qualifying Examination (QE). STUDY DESIGN: Scaled scores and the percent passing the 2011 ABS Surgery QE for individual residents and programs were compared between programs that subscribed to the SCORE portal in 2010 to 2011 and those that did not subscribe. Regression analyses were performed to control for program QE percent passing from 2004 to 2008 (baseline performance), as well as demographic factors known to affect examination results. RESULTS: There were 200 programs and 893 residents that subscribed to the SCORE web portal and 33 programs with 139 residents that did not subscribe. Regression analysis comparing predicted 2011 mean program QE scores based on 2004 to 2008 results showed that subscribing programs had a substantial increase in mean scaled scores of 1.4 points (adjusted means of 81.5 and 80.1, respectively), controlling for the percentage of international medical graduates and program size (p = 0.048). Residents from SCORE portal subscribing programs had a QE percent passing that was 1.6% higher than nonsubscribing residents, and the mean percent passing was higher for subscribing programs (86.4% vs 82.7%), but neither difference was statistically significant. The SCORE subscription status did not correlate with program size, percent of international medical graduates, or baseline scale scores. CONCLUSIONS: There was a considerable improvement in mean QE scaled scores for residents in programs that initially subscribed to the SCORE web portal. The percent passing the QE showed a trend toward improvement for subscribing programs and their residents. This association is promising and deserves additional investigation.
