Objective:To understand the current status of foreign dual-degree programs of Medical Doctor (MD) and Master of Public Health (MPH) and provide evidence-based decision-making reference for promoting the education of high-level applied public health talents in China.Methods:The list of involved institutions and information of foreign MD-MPH dual-degree programs was collected through literature retrieval, online information searching, and additional survey of key figures. We extracted the details of each project regarding professional fields, core competence, length of schooling, teaching and learning arrangement, internship eligibility, and graduation assessment. Python 3.8.0 was used for data cleaning, and the occurrence frequency of related items in each dimension was calculated.Results:A total of 99 MD-MPH programs from 104 foreign institutions were included, among which 97.1% of them were implemented in universities from the United States. The School of Public Health provided 42.4% (42/99) of the programs. Epidemiology was the major discipline set up among most programs, accounting for 12.0% (29/241) of all the specialties involved. Epidemiological research methods, health policy management and practice, and public health practice were the top 3 core competencies to be mastered. Of the 99 programs, 87 gave information on the length of the program, of which 74.7% (65/87) were five years, 6.9% (6/87) were four years, and 18.4% (16/87) included both 4-year and 5-year programs.Conclusions:The international MD-MPH programs were sophisticated and mainly organized by the School of Public Health alone or in conjunction with the School of Medicine. Epidemiology is the core course and competence objective, with a length of 4-5 years. Through learning experience from international MD-MPH programs and the Chinese unique medical development background, China should optimize its medical education system to develop a suitable talent training strategy for MD-MPH dual-degree programs in the new era.

Objective:To investigate the incidence and influencing factors of allergic reactions to cephalosporins.Methods:A cross-sectional study of 29 medical institutions in Zhejiang Province was conducted from April 2021 to June 2021.The incidence of allergic reactions to cephalosporins was investigated,and the influencing factors of cephalosporin-induced allergic reactions were analyzed by Poisson regression.Results:A total of 56 155 patients were included in this study.The total incidence of allergic reactions to cephalosporin was 1.67‰,the highest incidence of anaphylaxis occurred for ceftizoxime(4.27‰),followed by ceftriaxone(3.49‰)and cefotaxime(2.40‰).There was no significant difference in the incidence of allergic reactions between patients with negative skin tests and those without skin tests(1.75％o vs.1.63‰,RR=1.07,95％CI:0.70-1.63,P＞0.05).Poisson regression showed that body mass index(BMI)＜18.5 kg/m2(RR=2.43,95％CI:1.23-4.82,P＜0.05)and history of β-lactam antibiotics allergy(RR=33.88,95％CI:1.47-781.12,P＜0.05)increased cephalosporin-induced anaphylaxis.Compared with cefuroxime,the risk of allergic reactions was increased for ceftriaxone(RR=3.08,95％CI:1.70-5.59,P＜0.01),ceftazidime(RR=1.89,95％CI:1.03-3.47,P＜0.05),and ceftizoxime(RR=3.74,95％CI:1.64-8.50,P＜0.01).Conclusions:Lower BMI and history of β-lactam antibiotics allergy increase the risk of cephalosporin allergic reactions.The routine skin test may not reduce the occurrence of allergic reactions to cephalosporins. This study has been registered at Chinese Clinical Trial Registry(ChiCTR2200064314).
