Background and objective: Self-medication practice involves consumption of medicines by one’s own initiative or on the consultation of others without the guidance of a physician. Self-medication and use of over-the-counter drugs are prevalent worldwide public health concerns. University students of medical and nonmedical disciplines may have different levels of health education. This study evaluated the prevalence and patterns of self-medication and the attitudes toward this practice among medical and nonmedical university students in Jordan. Methods: A descriptive cross-sectional study was conducted in 504 students (medical: 248 and nonmedical: 256). The students were invited to complete a questionnaire that included questions primarily related to patterns of physician visits, self-medication practice, symptoms provoking self-medication, and sources of advice. Results: Self-medication was highly prevalent and comparable between medical and nonmedical students (~96%). Headache (81.9%), cold (58.3%), and flu (53%) were the frequent symptoms provoking self-medication among students. Self-medication for headache (86.7% vs 77.3%) and tooth pain (53.1% vs 27%) was significantly higher among medical vs nonmedical students, respectively. Self-treatment with painkillers (82.3% vs 73%) or antiallergy (11.3% vs 5.9%) drugs was significantly higher among medical students, while the use of anti-flu decongestants (47.6% vs 60.2%) was lower compared to nonmedical students, respectively. Nonmedical vs medical students were significantly more dependent on friends (14.8% vs 7.7%) and own experience (7.4% vs 2.4%) as a source of self-medication advice. Conclusion: Self-medication is common among Jordanian university students of medical and nonmedical disciplines. This practice, if used irrationally, may constitute a health problem that needs awareness and interventions by health care regulators in Jordan. Future studies are warranted to examine the impact of self-medication on students’ health.

Background: The contact-tracing COVID-19 technology allows for tracing people that come in contact to individuals with COVID-19 wherever they are located. The number of tracing COVID-19 infection technology and devices is rapidly increasing. This has prompted many researchers to study the acceptability and ethical issues related to the implementation of such technology. Aim: The purpose of this study was to determine the acceptability of COVID-19 contact-tracing technology and ethical issues of use. Methods: A cross-sectional questionnaire-based study was used. The target population was Jordanian adults (> 18 years). The survey was distributed to a convenience sample of 2000 general public in Jordan. Results: The results found that the number of people who accept to use COVID-19 contact-tracing technology was 71.6%. However, the percentage of people who were using this technology was 37.8. The main ethical concerns for many of participants were privacy, voluntariness, and beneficence of the data. Only income and living area were predictors for acceptability and use of tracing technology (p≤ 0.01). Conclusion: The majority of Jordanians accept the implementation of contact-tracing technology for COVID-19 infection. Among ethical concerns of the implementation of such technology were privacy, beneficence and voluntariness. Implications: The results of this study would help in improving the state of science regarding acceptability to use contact-tracing technology for health purposes. Moreover, the present findings provide evidence of predictors of acceptance and ethical concerns among Jordanian population about COVID-19 contact-tracing technology.

Context: Tobacco smoking represents a global public health threat, claiming approximately 5 million lives a year. Waterpipe tobacco use has become popular particularly among youth in the past decade, buttressed by the perception that the waterpipe “filters” the smoke, rendering it less harmful than cigarette smoke. Objective: In this study, we examined the acute exposure of waterpipe smoking on lung inflammation and oxidative stress in mice, and compared that to cigarette smoking. Materials and methods: Mice were divided into three groups; fresh air control, cigarette and waterpipe. Animals were exposed to fresh air, cigarette, or waterpipe smoke using whole body exposure system one hour daily for 7 days. Results: Both cigarette and waterpipe smoke exposure resulted in elevation of total white blood cell count, as well as absolute count of neutrophils, macrophages, and lymphocytes (P < 0.01). Both exposures also elevated proinflammatory markers such as TNF-α and IL-6 in BALF (P < 0.05), and oxidative stress markers including GPx activity in lungs (P < 0.05). Moreover, waterpipe smoke increased catalase activity in the lung (P < 0.05). However, none of the treatments altered IL-10 levels. Discussion and conclusion: Results of cigarette smoking confirmed previous finding. Waterpipe results indicate that, similar to cigarettes, exposure to waterpipe tobacco smoke is harmful to the lungs.

Background: Coronavirus disease 19 (COVID-19) has compelled implementing confinement measure across the globe. These measures can potentially lead to many changes in lifestyle. However, no studies examined the effect of COVID-19-induced confinement on physical activity (PA) and sedentary behavior (SB). Methods: During April and May of 2020, the current study surveyed changes in PA and SB induced by COVID-19 confinement. Results: The participants of the study were 1844. Among the participants who were regularly involved in PA, the majority (41.8– 42.2%) of the participants reported a “decrease” (p< 0.05) in walking, jogging, and sports while the majority (46.3– 53.1%) reported a “no change” (p< 0.05) in swimming, cycling, and weight lifting. With regard to the SB, most of the participants reported an “increase” in watching TV (72.3%), using electronics (82.7%), and logging to social media (81.9%). Additionally, gender, job type, obesity, and being worried to contract the disease were associated (p< 0.05) with changes in PA. On the other hand, age, gender, obesity, job type and income were related (p< 0.05) to changes in SB. Conclusion: Results of the current study might enhance knowledge about the impact of COVID-19 on lifestyle, particularly PA and SB. Subsequently, it can also be used to establish strategies to enhance engagement in activities during the current and future pandemics.
