Background: Shortages of qualified health workers have been a global concern, especially in developing countries. China also faces this dilemma, which hinders the development of public health services. Senior high school students are a group who are considering their college majors and careers after graduation. They are also a potential and basic talent reserve for the health sector. This survey focused on senior high school students' intention to learn clinical medicine and explored potential influencing factors. Methods: An anonymous questionnaire containing 20 items was distributed to 5344 senior high school students. The questions covered the following topics: students' intention to learn clinical medicine, personal and family information, understanding of medical education, cognition of doctors' working conditions, and doctor-patient relationships. Logistic regression and the chi-square test were used to compare students with and without a clear intention to learn clinical medicine to explore influencing factors. Results: Only 5.6% of senior high school students had a clear intention to learn medicine (CILCM). Personal and family information had distinct impacts. Interest and anatomy course were also associated with students' choice. There was a positive correlation between understanding of medical education and students' intention Meanwhile, students' cognition of doctors, career prospects, and social status had significant impacts. The more optimistic students were about doctors' working conditions and doctor-patient relationships, the more likely they were to have a CILCM. Conclusion: To some extent, this survey reflects the shortage of medical talent in China and provides possible clues for solving this problem. In addition, these findings may provide a perspective for understanding the development of health services in developing countries. [ABSTRACT FROM AUTHOR]

Aim of this study was to investigate the prevalence and genetic environment of the oxazolidinone resistance gene optrA in Streptococcus suis (S. suis) isolates from diseased pigs in China. A total of 178 S. suis isolates were screened for the optrA gene by PCR. The phenotypes and genotypes of optrA -positive isolates were investigated by antimicrobial susceptibility testing, core genome Multilocus Sequence Typing (cgMLST), capsular serotypes determination and whole-genome sequencing (WGS). Fifty-one (28.7%) S. suis isolates were positive for optrA. Phylogenetic analysis indicated that the spread of the optrA among S. suis isolates was primarily due to horizontal transfer. Analysis of S. suis serotypes from diseased pigs revealed substantial diversity. The genetic environment of optrA was complex and diverse and could be divided into 12 different types. Interestingly, we identified a novel integrative and conjugative element ICE Ssu 988S, carrying optrA and erm (T) genes. This is to the best of our knowledge the first report of the optrA and erm (T) co-located on an ICE in S. suis. Our results showed a high prevalence of optrA gene in S. suis isolates in China. Further research is needed to evaluate the importance of ICEs, as they horizontally propagate important clinical resistance genes. [ABSTRACT FROM AUTHOR]
