INTRODUCTION: The use of e-cigarettes has grown in popularity worldwide. From their manufacturing, use, and disposal, the environmental impacts of e-cigarettes present a novel public health concern that needs to be urgently investigated. However, very limited studies have focused on the subject matter. The present study aims to review available studies to identify the environmental impacts of e-cigarettes. METHODS: In this scoping review, we undertook a search in two databases (PubMed and Web of Science) from inception until 21 March 2023, and a gray literature search in Google Scholar. Reference lists of publications included in the scoping review were screened manually for additional relevant publications. Scientific publications that were in English and focused on the potential impacts of e-cigarettes on the environment were included. RESULTS: A total of 693 publications were identified, of which 33 were subjected to full-text review and 9 publications were finally included in the review. The impacts on air quality, water, land use, and animals, water and energy consumption, with associated environmental impacts, increased pollution and emissions due to greater e-cigarette production, having harmful and toxic components, creating pollution and waste issues, and global environmental impacts due to manufacturing and importing ingredients and components from low- and middle-income countries, were identified as the environmental impacts of e-cigarettes. CONCLUSIONS: Despite the emphasis on the environmental threat of e-cigarettes, there are limited scientific studies on the environmental impacts of the e-cigarette life cycle. Considering the rapid expansion of e-cigarette usage, there is an urgent need for a rigorous assessment of their life-cycle environmental burden of the various potential health, environmental, and other consequences.
BACKGROUND: during the last hundred years, several major public health issues have already afflicted humanity. Most frequently cited definitions of public health have stemmed from long-standing definitions, which raises several concerns including whether these definitions can respond to today's public health challenges. The present study aimed to identify and review available public health definitions in the first place. METHODS: in this scoping review, we undertook an electronic search in four databases (PubMed, Web of Science, Embase, and EBSCOhost) from inception until June 06, 2022, and a grey literature search in Google Scholar. Moreover, reference lists of publications included in the scoping review were screened manually for additional relevant publications. All types of scientific publications, in English, that focused on the definition of public health and provided an original definition were included. Year, type, disciplinary fields of publications, objectives of publications, and public health definitions were extracted. RESULTS: 5651 publications were identified through the scoping search, of which five were subjected to full-text review. Of these publications, two were included. An additional nine publications were identified through the manual screening. A total 11 of publications were included in the scoping review. Of the 11 definitions included in this review, the latest original definitions date back to about two decades ago. CONCLUSIONS: there is a noticeable lack of updated definitions of public health. Considering our findings and the ever-changing nature of public health issues, there is an urgent need for re-assessing and updating public health definitions.
In late 2020 and early 2021, with the eagerly anticipated regulatory approval of vaccines against SARS-CoV-2, the urgent global effort to inoculate populations against this devastating virus was underway. These case studies examine the early stages of COVID-19 vaccine rollouts across nine regions from around the world (Brazil, India, Indonesia, Ireland, Israel, Nigeria, Taiwan, United Kingdom and United States). By evaluating and comparing different approaches used to immunize against a novel pathogen, it is possible to learn a great deal about which methods were successful, and in which areas strategies can be improved. This information is applicable to the ongoing global vaccination against this virus, as well as in the event of future pandemics. Research was conducted by following and tracking the progress of vaccine rollouts in the nine regions, using published clinical trials, government documents and news reports as sources of data. Results relate to the proportion of populations that had received at least one COVID-19 dose by 28 February 2021. Outcomes are discussed in the context of three key pillars integral to all immunization programs: procurement of vaccines, communication with the public and distribution of doses to individuals.
Background: Patient information leaflet (PIL) which accompanies medicinal products and informs patients about dosage, side effects, etc., is known as a tool which empowers patients to be more involved in making decisions related to their medications and health. In recent years, policy makers have paid much attention to PIL and its lay-friendliness i.e. being clear,explicit, and easy to read and understand. In various countries, PIL is known as a legal genre and must be prepared in understandable language. The present study aimed to situate PIL within its institutional context and investigate the importance is given to the lay-friendliness of PIL in Iran. Methods: In this observational study, official website of Food and Drug Administration of the Islamic Republic of Iran (IFDA) was consulted. Iran's rules and regulations, legal requirements,linked to PIL production and translation were introduced and discussed in relation to lay-friendliness.. Results: Limited legislation relevant for the production and translation of lay-friendly PIL was found. The IFDA has not issued any documents or guidelines which exclusively concern lay- friendliness of PIL. Any methods which can assess lay-friendliness in original and translated PILs were not observed. Conclusion: The IFDA, the authoritative body in charge of legislation concerning PIL, has given limited importance to the language used in PIL and its lay-friendliness, witnessed by the limited legislation which is relevant for the production and translation of easy-to-understand PIL. It is not clear that how the IFDA assesses quality and lay-friendliness of original and translated PILs.
