The Practice and Exploration of Applying EBM to Bilingual Teaching of Medical Genetics at OSBCM

In the process of teaching medical genetics of undergraduate clinical medicine, the practice and exploration of applying EBM to the bilingual teaching of OSBCM medical genetics are carried out. Using CBL and PBL as the carrier can make up for the shortcomings of a single teaching mode, synthesize the advantages of multiple teaching modes. It starts from integrating the basic theoretical knowledge of medicine and clinical practice knowledge, improving students’ bilingual level of medical genetics, cultivating students’ literature retrieval ability, and promoting early clinical, multi-clinical and repeated clinical consciousness for medical students. Therefore, it is more conducive to cultivate students’ ability to learn independently, accurately analyze and solve problems, improve medical students’ clinical thinking ability and scientific research awareness, improve medical students’ ability of international communication, and lay a solid foundation for improving medical students’ future post competence, innovative spirit and lifelong learning ability.

A Review on the 3D Printing of Functional Structures for Medical Phantoms and Regenerated Tissue and Organ Applications

Medical models, or ＂phantoms,＂ have been widely used for medical training and for doctor-patient interactions. They are increasingly used for surgical planning, medical computational models, algorithm verification and validation, and medical devices development. Such new applications demand high-fidelity, patient-specific, tissue-mimicking medical phantoms that can not only closely emulate the geometric structures of human organs, but also possess the properties and functions of the organ structure. With the rapid advancement of three-dimensional （3D） printing and 3D bioprinting technologies, many researchers have explored the use of these additive manufacturing techniques to fabricate functional medical phantoms for various applications. This paper reviews the applications of these 3D printing and 3D bioprinting technologies for the fabrication of functional medical phantoms and bio-structures. This review specifically discusses the state of the art along with new developments and trends in 3D printed functional medical phantoms （i.e., tissue-mimicking medical phantoms, radiologically relevant medical phantoms, and physiological medical phantoms） and 3D bio-printed structures （i.e., hybrid scaffolding materials, convertible scaffolds, and integrated sensors） for regenerated tissues and organs.

Peculiarities of Medical Personnel Behavior Styles in Conflict Situations

Introduction: Leadership style is a way, a system of methods of influence of the leader on subordinates. This is one of the most important factors of the effective work of the institution, the full realization of the potential capabilities of people in the team. Leadership style, as an individual way of carrying out management activities, is mostly associated with the person of the manager. The management style is formed under the influence of the relationship between the manager and the team in the process of making and implementing management decisions, individual characteristics and preferences of the manager. The objective of the study was conflicts in the field of healthcare in the system “medical personnel of a healthcare institution—patients and relatives of patients”. The objective of the study was to determine management styles in conflict situations among medical workers. Materials and Methods: With the help of a direct individual survey, according to an anonymous questionnaire developed by us, the opinion of 582 medical workers (422 doctors and 160 nurses) of general hospitals and primary care centers of Chernivtsi and Chernivtsi region regarding the ceilings of behavior in conflict situations was studied. Results: In a conflict situation, the leading form of behavior for medics, both doctors and medical personnel, is the subordinate type (29.6% and 38.1%, respectively). The second most frequent method of conflict resolution is an authoritarian strategy (20.6% for doctors and 15% for nurses), in which personal aspirations and the achievement of one’s own goals come to the fore. Dependent style (17.8% for doctors and 13.75% for nurses) ranks third. A selfish style of behavior in a conflict situation is characteristic of 13.7% of doctors and 13.1% of nurses. A friendly style of behavior during the resolution of conflict situations is characteristic of medical workers at a rather low level (12.3% for doctors and 12.5% for nurses). Aggressive style (5.9% for doctors and 7.5% for nurses) is the least popular as a model of behavior in a conflict situation among respondents. Conclusion: The style of behavior of doctors and nurses in conflict situations is ambiguous, which is due to personal qualities, the degree of leadership, professional relationships and the specifics of the work environment.

Quantitative Assessment of Medical Waste Management in Hamad Medical Corporation—Qatar

A proper waste management system is very important in healthcare facilities because the overall benefit outweighs the cost. In the healthcare sector, hazardous health care waste (HHCW) consists of wastes that are potentially contaminated by dangerous agents. Identification and segregation of HHCW is harbinger for its proper management. The quantitative analysis study on HHCW had not been done in Qatar government hospitals. This study quantitatively analyzed the current practice for HHCW management in Hamad Medical Corporation (HMC), Qatar. The objective of this study is to provide a first comprehensive assessment of hazardous healthcare waste managements in Qatar and offers an opportunity to improve existing practice. This is a retrospective survey study carried out on secondary data collected from the department of occupational health and safety (OHS), HMC. OHS department collects and keeps records of hazardous wastes produced by HMC. Data on the HMC hospitals’ characteristics from 2017 to 2019 were retrieved from Planning and Statistics Authority’s website. World Health Organization (WHO) formula for calculating HHCW generation rate was used to calculate the rate for HMC. Data analysis results show a steady increase in HHCW generation rate in HMC, the generation rate was 2.6 Kg/patient bed/day, 2.8 Kg/patient bed/day and 3.1 Kg/patient bed/day for the years 2017, 2018 and 2019 respectively. There were also significant variations in HHCW generation rates between hospitals. The highest generation rate was 4.64 Kg/patient bed/day recorded for AWH and the lowest was 0.2 Kg/patient bed/day recorded for mental health and both hospitals contributing 23.18% and 0.29% respectively of HHCW in HMC.
