The use of e-cigarettes has been increasing in popularity among people, especially young adults. Assessing young individuals’ perceptions of e-cigarettes can help to identify factors that may influence their decision to use e-cigarettes. To examine prevalence, perceptions, and knowledge of e-cigarettes among university students in Jordan, an observational cross-sectional study using an online self-administered questionnaire was conducted among students from public and private universities between October 2020 and January 2021. A total of 1259 university students completed the questionnaire. Approximately, 11% of participants reported e-cigarettes use. Among users, 26.5% used it for the purpose of smoking cessation, while 22% of them used it out of curiosity, and 20.5% used it as they believed it is less harmful than other tobacco products. Multivariate analysis showed that conventional cigarette smokers were independently associated with a better knowledge about e-cigarettes (OR = 1.496, 95CI% = 1.018–2.197, p-value = 0.040). In addition, medical students showed a significantly better knowledge compared to non-medical students (OR = 1.710, 95CI% = 1.326–2.204, p-value = <0.001). In Jordan, e-cigarettes use is less popular compared to other countries. Nonetheless, educational interventions are needed to correct misconceptions about e-cigarettes among young adults.

Waterpipe tobacco smoking has increased in prevalence worldwide, including among pregnant women. In this study, we investigated the effect of prenatal maternal waterpipe tobacco smoke (WTS) exposure during different stages of pregnancy on learning and memory of adult offspring rats. Pregnant rats received either fresh air or mainstream WTS (2 hours daily) during early, mid, late, or whole gestational period. Male offspring rats were followed through 20 weeks. Outcomes included (1) spatial learning and memory using the radial arm water maze (RAWM), (2) levels of brain derived neurotrophic factor (BDNF) in the hippocampus, and (3) oxidative stress biomarkers (superoxide dismutase, catalase, glutathione peroxidase and thiobarbituric acid reactive substances). Relative to offspring whose mothers were exposed to fresh air, prenatal exposure to WTS at any stage of pregnancy resulted in short- and long-term memory impairment in adult offspring rats (p < .05). This impairment was associated with reduced levels of BDNF in hippocampus (p < .05). However, prenatal WTS did not affect the level of oxidative stress biomarkers in hippocampus. Prenatal WTS during late gestation increased the activity of catalase as compared to control. Prenatal maternal WTS exposure can impair the memory of adult male offspring. These results support development of interventions that target pregnant women who smoke waterpipe during pregnancy. We examined for the first time the effect of prenatal waterpipe tobacco smoke exposure on learning and memory of offspring. The results showed that in utero exposure to waterpipe tobacco smoke was associated with impaired memory and decreased brain derived neurotrophic factor in hippocampus of adult male offspring rats.

Introduction: A wealth of evidence reveals the benefits of breastfeeding. During the breastfeeding period, nursing mothers may face many medical conditions that require medical management. The medication use among breastfeeding women in Jordan is largely unknown. Objective: This study assessed the beliefs and attitudes of breastfeeding women in Jordan toward medication use. Methods: The data were collected from breastfeeding women in hospitals and maternal and children care centers from north, middle, and south Jordan by semistructured interviews using a self-administered questionnaire from February 2015 to November 2015. Results: Of the 903 participants (96% response rate), 17% used over-the-counter medications and 33% took prescribed medications. Of these, 7% (n = 64) used both over-the-counter and prescribed medications. Analgesics followed by antibiotics were the most commonly used medications among breastfeeding women in Jordan. The majority of breastfeeding women consulted with their physician or pharmacist before initiating or changing any medication. Product Information was the most commonly used drug information resource utilized by breastfeeding women to inquire about safety of medication use during breastfeeding. Conclusion: Breastfeeding women should be educated about the reliable sources of medication information and the importance of physician consultation before initiation or modification of medication therapy. Physicians and pharmacists should be encouraged to be actively involved in detailed discussion with breastfeeding women regarding medication use.

Background: The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the etiology of COVID-19 pandemic, resulted in significant harm to the affected countries in every aspect of life. The virus infected over 139 million patients and resulted in over 2.9 million deaths until April 16, 2021. New variants of this virus were identified that spread rapidly worldwide. Summary: Remdesivir, a prodrug of adenosine nucleotide analog, is an antiviral with a broad spectrum of activity that was tested on SARS and Middle East respiratory syndrome infections. In vitro studies conducted on SARS-CoV-2 revealed that remdesivir inhibited viral replication with high selectivity index in cell cultures. In vivo studies showed that remdesivir reduced viral load in bronchoalveolar lavage fluid and attenuated pulmonary infiltrates in infected animals. Further, remdesivir showed promising results in terms of clinical improvement, shortening the recovery time, mortality rate, and the duration of oxygen need, despite that some clinical trials did not reveal significant effect on remdesivir use. Several studies showed positive results of remdesivir against the new variants. Key Messages: Remdesivir showed a promising beneficial effect against new variants of SARS-CoV-2, but more clinical evidence is needed to confirm this effect.
