Safety of higher doses of melatonin in adults: A systematic review and meta-analysis.

Melatonin is commonly used for sleep and jetlag at low doses. However, there is less documentation on the safety of higher doses, which are being increasingly used for a wide variety of conditions, including more recently COVID-19 prevention and treatment. The aim of this review was to investigate the safety of higher doses of melatonin in adults. Medline, Scopus, Embase and PsycINFO databases from inception until December 2019 with convenience searches until October 2020. Randomised controlled trials investigating high-dose melatonin (≥10 mg) in human adults over 30 years of age were included. Two investigators independently abstracted articles using PRISMA guidelines. Risk of bias was assessed by a committee of three investigators. 79 studies were identified with a total of 3861 participants. Studies included a large range of medical conditions. The meta-analysis was pooled data using a random effects model. The outcomes examined were the number of adverse events (AEs), serious adverse events (SAEs) and withdrawals due to AEs. A total of 29 studies (37%) made no mention of the presence or absence of AEs. Overall, only four studies met the pre-specified low risk of bias criteria for meta-analysis. In that small subset, melatonin did not cause a detectable increase in SAEs (Rate Ratio = 0.88 [0.52, 1.50], p = .64) or withdrawals due to AEs (0.93 [0.24, 3.56], p = .92), but did appear to increase the risk of AEs such as drowsiness, headache and dizziness (1.40 [1.15, 1.69], p < .001). Overall, there has been limited AE reporting from high-dose melatonin studies. Based on this limited evidence, melatonin appears to have a good safety profile. Better safety reporting in future long-term trials is needed to confirm this as our confidence limits were very wide due to the paucity of suitable data.

Pharmacists' awareness of COVID-19 and perceptions of their roles, barriers, and roles of policymakers: Exploring the Middle East and North Africa (MENA).

BACKGROUND: The coronavirus disease (COVID-19) was declared in January 2020 as a public health emergency of international concern. The Middle East and North Africa (MENA) suffered from several pandemics previously. Pharmacists have vital roles to play to prevent the spread of this virus. OBJECTIVES: To assess the COVID-19 awareness amongst pharmacists from Arabic-speaking countries located in the MENA region, and to assess their perspectives of their role, barriers, and roles of the educational institutions/pharmaceutical associations. METHODS: An online survey was conducted to run a descriptive cross-sectional study in Jordan from 12th to 22nd April 2020. The questionnaire was validated (face validity) and put on Facebook and directed for pharmacists only (clarified in the introduction of the questionnaire). Assessment of pharmacists' awareness (20 questions) about pandemics and COVID-19, their perceived roles and barriers, and roles of the educational institutions (eg, universities) and pharmaceutical associations (eg, Pharmacists Syndicate) was performed. Data were analysed using Statistical Package for the Social Science (SPSS). RESULTS: Study participants (n = 2589) had a mean age of 29.3 (8.2) years and 1329 (51.5%) were females. Most of the participants were from Egypt (n = 819, 40.8%), followed by Jordan, Algeria, and Syria. Regarding the sources of information about coronavirus management, 60.8% of participants got their information from social media. Fear of contracting the coronavirus while performing their duties was reported by the majority of pharmacists as the main barrier to delivering their roles (82.3%). The majority of pharmacists identified positive roles for the pharmaceutical institutions (74.8%) and pharmaceutical associations (63.6%). CONCLUSION: Pharmacists from the MENA countries believe they got enough education previously about pandemics, and the majority follow the latest coronavirus updates from social media. Fear was reported as the major barrier that requires resolution by the policymakers. Certain gaps in the awareness about COVID-19 were identified.

Pharmacists' perceived barriers towards delivering their emergency roles during the COVID-19 pandemic and perceived policymakers' responsibilities.

RATIONAL: In March 2020, the World Health Organization (WHO) declared the coronavirus infectious disease as a pandemic referred to as COVID-19. As an essential service, community pharmacists have been enacting a key role in patient counseling and supply of essential medicines and protective equipment. OBJECTIVES: To investigate pharmacists' perspectives of the role of educational institutes and professional pharmacy organizations in supporting them to take on roles during COVID-19 pandemic and to identify barriers to be able to support themselves and their patients. METHODS: This descriptive mixed-method study was conducted via a cross-sectional online survey distributed to pharmacists/pharmacy students in Jordan during the COVID-19 outbreak (15-30 March 2020) using an online questionnaire, followed by an online focus group. Questionnaire items related to participants' perspectives in being prepared for and supported in their roles during the COVID-19 pandemic, and items were tested for face validity. Data were descriptively analyzed using the Statistical Package for the Social Sciences and triangulated with focus group findings. RESULTS: Considering that fear and anxiety are a consequence of mass social distancing/quarantine, study participants (n = 726, age = 26.9 (SD = 8.0) years, 71.9% females), reported needing training on mental healthcare to be able to support themselves and people during pandemics (90.2%). Most respondents agreed/strongly agreed (59.7%) with the statement around pharmacy educators/educational institutes having a key role in preparing pharmacists for practice during epidemics/pandemics and agreed that their faculties should add a course regarding pandemic preparedness in their curriculum (89.9%). Results were similar regarding roles for the pharmaceutical associations. Focus group findings (n = 7) mirrored the survey findings to a large extent. CONCLUSIONS: Most participants believed that pharmacy educators and pharmaceutical associations have a role in preparing them to deal with the COVID-19 pandemic through online educational workshops/webinars. Online education on mental healthcare is specifically needed.

Pharmacists' readiness to deal with the coronavirus pandemic: Assessing awareness and perception of roles.

Background: The 2019 Coronavirus infection (COVID-19) caused by a novel strain of coronavirus was detected in China in December 2019, and declared a public health emergency of international concern on January 30, 2020. Community pharmacists have an important role in supporting the local health emergency preparedness and response arrangements. Objectives: To investigate pharmacists and pharmacy students' awareness and source of their information regard the management of the coronavirus pandemic, and their perspective of their role during this emergent situation. Methods: This descriptive cross-sectional online survey study was conducted in Jordan during the COVID-19 outbreak (from 15 to 30 March 2020). A validated online questionnaire addressing participants' current awareness about epidemics/pandemics and COVID-19, source of information and their perspectives of their role. Data were analyzed using statistical package for social science (SPSS). Results: Participants (n = 726) had a mean age of 26.9 (8.0) years with 71.9% females. Pharmacy students made 35.3% of the sample while the rest were pharmacists. Only 54.3% of participants believed that they got enough education about epidemics/pandemics, and 94.6% of them follow on the latest coronavirus updates on treatments, and that is mainly from the media (59.5%) followed by the World Health Organization reports (58.7%) and then the published researches (57%). Awareness score (out of 20) of pharmacists (n = 470) was significantly higher (p < 0.001) than that of students (n = 256). Better Awareness scores were also associated with higher age of participants, graduating from a public versus a private university, and attending more educational workshops. Conclusion: The majority of pharmacists and pharmacy students reported that they have a major role in the management of epidemics/pandemics through the community pharmacies but the majority follow on the latest coronavirus updates from the media. This fact rings bills considering the numerous conflicting messages publicized during the pandemic through the media.
