<b><i>Background:</i></b> Colorectal cancer (CRC) is a rare disease amongst children and adolescents. Previous studies have reported a number of differences between children/adolescents, young adults, and adult patients with CRC. However, none of these studies compared these age groups according to their clinicopathologic and prognostic characteristics. In the current study, we compare these three age groups. <b><i>Methods:</i></b>A total of 173 (1.1% of 15,654 patients) young CRC patients (≤25 years) were included in the study. As a control group, 237 adult CRC patients (>25 years) were also included. Patients were divided into three age groups: child/adolescent (10–19 years), young adult (20–25 years), and adult (>25 years). <b><i>Results:</i></b> Statistical differences amongst the three groups in terms of gender (<i>p</i> = 0.446), family history (<i>p</i> = 0.578), symptoms of presentation (<i>p</i> = 0.306), and interval between initiation of symptoms and diagnosis (<i>p</i> = 0.710) could not be demonstrated. Whilst abdominal pain (<i>p</i> < 0.001) and vomiting (<i>p</i> = 0.002) were less common in young adults than in other groups, rectal bleeding and changes in bowel habits were relatively less common in adolescents than in other groups. Rectal localisation (<i>p</i> = 0.035), mucinous adenocarcinoma (<i>p</i> < 0.001), and a poorly differentiated histologic subtype (<i>p</i> < 0.001) were less common in the adult group than in other groups. The percentage of patients with metastasis and sites of metastasis (e.g., peritoneum and lung) differed between groups. The median overall survival was 32.6 months in the adolescent group, 57.8 months in the young adult group and was not reached in the adult group (<i>p</i> = 0.022). The median event-free survival of the adolescent, young adult, and adult groups was 29.0, 29.9, and 61.6 months, respectively (<i>p</i> = 0.003). <b><i>Conclusions:</i></b> CRC patients of different age groups present different clinicopathologic and prognostic characteristics. Clinicians should be aware of and manage the disease according to these differences.
A significant portion of the problems faced by veterinarians is related to communication. These problems are intensely experienced between veterinary practitioners and animal owners; yet no lectures or courses aiming to improve professional skills are available in the curriculum of veterinary schools in Turkey. In this study, all students currently enrolled at, and 1992 and 1998 graduates of, the Veterinary School of Firat University (VSFU), Turkey, were surveyed to evaluate the attitudes of veterinary students and graduates toward technical and professional skills. Data were collected from 581 students and 61 recent graduates via personal interviews with students and questionnaires mailed to graduates; information was obtained about participants' technical and professional skills. The overall response rate was 85%. The results show that learning about technical and professional skills is highly valued; competence and comfort in skill sets are associated with comfort in establishing communication with instructors. Positive correlations were also noted between feeling comfortable with and feeling competent in both skill sets. In conclusion, it appears to be essential to introduce courses addressing improvement of professional skills to the curriculum of veterinary schools in Turkey, given that a successful veterinarian profile requires feeling competent in and comfortable with both technical and professional skills.
Objective: The rates of and the factors influencing HER2 discordance in patients receiving neoadjuvant therapy for breast cancer are investigated. Methods: This study retrospectively examines the rates of HER2 and hormone receptor discordance between the biopsy and postoperative resection specimens of 400 female early-stage breast cancer patients. Results: One hundred and thirty-three (33.3%) patients had received neoadjuvant therapy. The rate of HER2 discordance between biopsy and resection specimens was 1.7% in the control group and 5.3% in the neoadjuvant therapy group (p = 0.018). The rate of HER2 discordance was higher in younger patients and in patients with T1 tumors in the neoadjuvant therapy group. Conclusion: Neoadjuvant therapy, age <40 years and smaller tumor size were independent risk factors for HER2 discordance.
ABSTRACT:In this study, veterinary students and veterinary educators from Firat Veterinary School, Istanbul Veterinary School and Selcuk Veterinary School were surveyed to evaluate their a�itudes to animal use in research. Data were collected from 330 students and 204 educators by personal interviews. All participants showed anthropocentric a�itudes toward animal use in research. Most of the participants agreed on items regarding the animal tests being easier, more scientific, more common, more economical and more reliable than alternative methods, but they also signified that they did not agree with the item indicating that the animal experimentation is more conscience. In conclusion, we can state that both the veterinary students and the educators are in a complete dilemma in the discussions regarding the animal experimentation. In order to avoid the negative circumstances that can arise from this dilemma, it could be said that veterinary schools should be supported in this aspect with related courses to be included within their curriculum.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
