Volume 1, Issue 2 (2-2008)
Abstract

Background and aim: One of the most important technological advancements for monitoring patients -- especially in anesthesia, recovery, and Intensive Care stages -- is pulse oximetry which can measure the oxygen saturation of arterial blood (spo2) and show hypoxemia before it is clinically observable. Therefore, it is necessary for the individuals who are responsible for treating and taking care of patients in critical stages to have sufficient knowledge about it. If they lack the required knowledge, they should be trained using appropriate methods.

Materials and methods: Upon referring to the ORs and the ICUs, a questionnaire was distributed among the medical and paramedical staff (doctors, nurses, anesthesia technicians, etc.) to assess their knowledge of pulse oximetry. The questionnaire had a part for demographic data and 20 true/false items and was to be filled in by the subjects in 15 minutes. After the data were collected and analyzed, the subjects' level of knowledge about pulse oximetry was assessed in terms of age, sex, academic degree, their experience with the device, and how they had obtained information about pulse oximetry. The variable was measured on a 0-20 scale. The subjects would get one point for every correct response and the total number of correct responses would constitute each individual's score.

Results: The results of the study show that only 15.8% of the participants had a high level of knowledge of pulse oximetry. The figure was 61% for those having medium-level knowledge and 23.2% for the individuals with low knowledge. In other words, for the optimal use of the device, 84.2% of the subjects need training. The results also indicate that the subjects' level of knowledge is positively related to their sex, academic degree, and how they acquired their knowledge. In fact, female subjects, paramedical staff, and those who had obtained information from colleagues and the companies selling the device had a lower level of knowledge needed for using the device properly. However, no statistically significant difference was found between the subjects' knowledge of pulse oximetry and their age and experience with the device.

Conclusion: Based on the findings, it is necessary for the female members of paramedical staff to be trained in classes and/or be provided with pamphlets on the issue.

Volume 9, Issue 1 (5-2015)
Abstract

Background and Aim: Medical Laboratory Sciences is one of the important fields in Medicine that is closely associated with other disciplines in this group. This study aims to evaluate laboratory sciences curriculum in Iran and several countries worldwide.

Materials and Methods: In this research, data collection is based on documents and curriculum goals of countries. The data collected was analyzed using qualitative methods.

Results: Comparative study of curriculum courses of bachelor of Laboratory Medical sciences was done and compared with the number of basic and specific units in Iran and other countries.

The curriculum in Iran with Turkey and Australia is remarkably consistent. Internship units in hospitals have lower returns in compared to other universities in the world.

Conclusion: Laboratory Science curriculum in Iran is matched with developing countries. However, more attention to training units and projects to improve the quality of teaching laboratory sciences could be more effective.


The Effects of Long-term and Simultaneous Administration of Methylphenidate and Nicotine before and During Pregnancy on the Microscopic Structure of Testicular Tissue in Male Offspring of Mice

Abstract
Background and Aim: Methylphenidate (MPH) is one of the commonly used drugs in the treatment of hyperactivity disorder in children. The use of MPH has been associated with increased activity of the central nervous system so may lead to the abuse of this compound. Nicotine is one of the compounds available in a wide range of people in various forms. The negative effects of nicotine on pituitary-testicular axis and spermatogenesis have been reported. In this study, the effects of long-term and simultaneous administration of methylphenidate and nicotine before and during pregnancy in mice on the microscopic structure of testicular tissue in newborn babies were evaluated.
Materials and Methods: Adult mice received nicotine and methylphenidate for eight weeks before and during pregnancy. Embryologic indices and microscopic structure of testicular tissue were evaluated in newborn babies.
Results: The results showed that embryologic and histologic indices in newborns from treated mice decreased in comparison to control group. A decrease of cellular population of seminiferous tubules and development of some structural changes in seminiferous tubules has been observed in treated groups.
Conclusion: The results of this study showed that the simultaneous administration of nicotine and methylphenidate before and during pregnancy could induce some structural alterations in testicular tissue in embryonic development and postnatal period.

Perceptions of Operating Room and Anesthesia Students and Instructors Regarding the Impact of the Hidden Curriculum on the Promotion of Professional Ethics

Volume 19, Issue 4 (11-2025)
Abstract
Background and Aim: The hidden curriculum is considered the most powerful means of transmitting professional values. Given the critical importance of managing the hidden curriculum to institutionalize professional ethics and professionalism within health higher education institutions, the present study was conducted to explore the perceptions of operating room and anesthesia students and instructors regarding the impact of the hidden curriculum on the promotion of professional ethics.
Materials and Methods: This study was conducted using a qualitative approach based on conventional content analysis. The study population included final-year students and instructors from the operating room and anesthesia disciplines at Hamadan University of Medical Sciences. Participants were selected through purposive and theoretical sampling methods. Data were collected via in-depth, semi-structured interviews. Data saturation was achieved after conducting 24 interviews. The data analysis followed the qualitative content analysis approach proposed by Graneheim and Lundman (2004), and was carried out in seven steps: 1. familiarization with the data, 2. identification of meaning units, 3. initial coding, 4. formation of subcategories, 5. development of categories, 6. extraction of themes, and 7. final review.
Results: The content analysis of the interviews resulted in the identification of 456 initial codes. Following refinement and consolidation, these codes were organized into four overarching categories and ten subcategories. The main categories comprised: ‘Components of the hidden curriculum in professional ethics education’, ‘Mechanisms through which the hidden curriculum exerts influence’, ‘Consequences of the hidden curriculum’, and ‘Strategies for enhancing professional ethics’. The findings indicated that the hidden curriculum, manifested through the behavioral patterns of faculty members and instructors, organizational culture, and interpersonal interactions, plays a pivotal role in shaping students’ ethical attitudes and behaviors. Furthermore, the hidden curriculum, through processes of unconscious learning, reinforcement or erosion of formal values, and the manner in which rules are implemented, can yield both positive outcomes—such as the development of ethical decision-making skills—and negative outcomes, including diminished ethical sensitivity.
Conclusion: This study revealed that the hidden curriculum in operating room and anesthesia education functions as a dual-force phenomenon. On one hand, it fosters the development of professional ethics through constructive role modeling and authentic clinical experiences. On the other hand, it can contribute to ethical erosion by conveying contradictory messages and unhealthy norms. Achieving sustainable ethical learning requires active management of the hidden curriculum through three key strategies: aligning the formal and hidden curricula, empowering instructors as agents of ethical value transmission, and shifting the organizational culture paradigm toward learning from error.
