Many people experience stress daily. While there is a close relationship between stress and mental health, psychological stress and its associated emotions, such as anger, anxiety, and depression, can also exert harmful effects on physical health. An electroencephalogram (EEG) is an electrophysiological monitoring device for recording electrical activity within the cortex. The EEG was originally developed to evaluate the human brain cortical activity. The nature of background activity in human brains, and how it reflects behavior and cognitive processes, has been of foremost interest to scientists since Hans' discovery of the alpha rhythm [1]. Recently, certain oils were found to decrease blood pressure, heart rate, and skin temperature, with accompanying autonomic arousal and subjective reports of feeling refreshed [2]. These oils may simultaneously increase the power of theta (4-8Hz) and alpha (8-13Hz) rhythms. Progressive muscle relaxation was found to be associated with an increase of posterior theta (3.5-7.5Hz) and a decrease of mid-frontal beta-2 band (20-29.5Hz) [3]. Taking these facts into consideration, we aimed to examine possible changes in EEG activity in response to varying degrees of work load (i.e., stress) in our facility's medical professionals. MethodsA prospective cohort study of 73 medical professionals from KFMC was performed, with sample size having been determined by a biostatistician as sufficient to determine the relationship between EEG activity of participants during working days relative to nonworking days. A significant proportion of participants comprised volunteer nurses. The

Plagiarism is one of the most common research misconducts and has many negative consequences. It can potentially destroy the reputation of an institution. Only a few studies have explored plagiarism in Saudi Arabia, and these have focused on academic institutions. Therefore, in this study, we investigated the attitudes of researchers towards plagiarism at a tertiary care hospital in Riyadh, Saudi Arabia, using the established Attitudes Towards Plagiarism questionnaire. The questionnaire contains demographic data along with 29 statements divided into three sections: positive attitude towards plagiarism, which reflects the approval and acceptance of plagiarism (12 items); negative attitude towards plagiarism, which reflects deprecation and condemnation of plagiarism (7 items); and subjective norms towards plagiarism, which reflects personal perception of the extent and acceptance of plagiarism in society (10 items). Responses were collected from 237 participants. The overall attitudes of researchers showed a disapproval for plagiarism in medical research but also revealed some ambiguity about self-plagiarism and a belief that others were more likely to plagiarize than the respondent. Our findings suggest that awareness about different forms of plagiarism among researchers should be increased. We recommend that researchers' attitudes towards plagiarism should be investigated further in a rigorous association study.

Contract cheating and ghostwriting are forms of misconduct that are unethical and a serious academic issue, especially among healthcare professionals, as they directly impact patient health. To date, research on this area in the Middle East has been limited. Therefore, we used a validated self-administered questionnaire to investigate the awareness, perceptions, and reasons for these behaviors among 682 students in health specialties at five universities in Riyadh, Saudi Arabia. The majority of the students (60.1%) were unaware of the terms “contract cheating” and “ghostwriting,” and 69.5% had not received any prior training on integrity. However, having prior training had a positive effect on awareness levels, and respondents attending private universities were significantly more aware than those attending public universities. The factors that contributed to contract cheating behavior included poor time management, English language difficulties, and a lack of writing skills. These findings emphasize the need for integrity training at the national level to raise awareness.
