Background and Objective: Rapid aging and climate change are two major global challenges of the 21st century. This study was conducted to identify the effects of climate change on the health of older adults. Materials and Methods: This systematic review was conducted by comprehensively searching the Scopus, PubMed, and Web of Science electronic databases using the keywords elderly, aging, older people, health, and climate change, in English. Articles from 2014 to February 2023 following the PRISMA checklist were examined. Studies were included if they were published in English, had full text available, and focused on a population of people over 60 years old. Simulated studies were excluded. Results: The quality of these studies was reported to be moderate to good according to the STROBE checklist. The results showed that climate change negatively impacts the physical, mental and social health of the elderly. It causes an increase in the prevalence of cardiovascular, kidney, and respiratory diseases, as well as depression. Additionally, it leads to a reduction in daily activities, an increase in hospitalization rates and higher mortality. Among various climate changes, the increase in temperature poses the greatest to the health of older adults. Conclusion: Climate changes, particularly the rise in temperature, have the most significant negative impact on the physical health of older adults. Therefore, there is a pressing need for increased focus on environmental sustainability, the development of public health intervention policies, and the implementation of adaptive strategies to mitigate the effects of extreme temperatures for older adults.

Background and Objective: The presence of toxic compounds, including phenol, due to industrial development, poses a threat to the environment. Utilizing hairy roots has emerged as a potential method to remove these toxins. This review aims to explore the efficacy of hairy roots in absorbing phenol pollutants and the influencing parameters. Materials and Methods: This study was conducted using a descriptive-review method based on existing literature gathered from databases such as Science Direct, PubMed, and Google Scholar. The focus of the study was on the purification of phenol using hairy roots. Keywords such as Phytoremediation, Hairy root, Phenol, and Transgenic roots were used for data collection. Results: Results show successful phenol removal by hairy roots, potentially attributed to abundant production of peroxidase enzymes. Various factors, such as hydrogen peroxide (H2O2), incubation time, pH, plant species, and pollutant concentration, impact phenol removal efficiency. Notably, plants like Brassica napus, rich in peroxidase enzymes, exhibit high efficiency in removing phenol pollution up to 500 mg/L, with H2O2 and within a pH range of 4-9. Conclusion: In conclusion, hair roots possess significant adsorption capacity for phenol. However, phenol concentration, contact time, pH, and temperature influence their performance. Therefore, further research is required to explore optimal conditions for phenol removal. [ABSTRACT FROM AUTHOR]

Background: As social networks are increasingly used, the research published through social networks should be evaluated. Hence, new measures were employed to examine the scientific effectiveness of social networks. The measurements taken from social networks, called Altmetrics, provide an opportunity to evaluate research. Therefore, this study aimed to investigate the presence of indexed articles of researchers affiliated with Bushehr University of Medical Sciences at the Scopus site in social networks. Materials and Methods: The present applied study used altmetrics to determine articles with the highest altmetrics score. Data was collected form June 22nd to August 23rd, 2018 from Scopus database, and analyzed using descriptive and analytic statistics (Pearson’s correlation coefficient) in Excel and SPSS version 20. Results: The findings of this study showed that out of 679 articles incexed for Bushehr University of Medical Sciences in Scopus database, 128 articles in social networks had altmetrics score in different social networks. The study of various networks showed that Mendely (79.79%), Twitter (8.58%) and Dimensions (6.86%) were the most important social networks that users visited or shared through the research articles. Finally, we found a positive and significant relationship between altmetrics and citation indicators of articles, Conclusion: It can be said that altmetrics can be used as a complement to citation indicators to evaluate the performance of researchers.

Background and Objective: Environmental burden of disease (EBD) studies are one of the most important needs for determining the current situation, increasing the effectiveness of health policies and programs and prioritizing environmental health interventions. This review article was evaluated the status of the EBD in Iran based on the results of the latest Global Burden of Disease (GBD) Study, other international studies and national estimates in the country. Materials and Methods: In this study, the researches on the EBD in Iran were identified by searching in the international and national scientific databases and the search results were studied and analyzed. Results: The review of the EBD studies showed that based on the results of the GBD study, the share of environmental risk factors in the total burden of diseases in the country in 2017 according to the disability-adjusted life years (DALYs) and deaths were about 8 and 13%, respectively. According to the results of the GBD study, the contributions of environmental risk factors in the attributable DALYs in the country in 2017 (a total value of 1,648,329) were as follows: ambient air PM2.5 for 45.0%, occupational risk factors for 25.1%, exposure to lead for 19.4%, unsafe water source for 5.0%, tropospheric ozone for 1.7%, lack of access to handwashing facility for 1.5%, unsafe sanitation for 1.4%, residential radon for 0.6%, and household air pollution from solid fuels for 0.3%. The total DALY rate and death rate attributable to solar ultraviolet radiation in Iran in 2000 were estimated to be 46.2 and 0.7, respectively. The DALY and the DALY rate attributable to elevated levels of fluoride in drinking water due to dental fluorosis in the country in 2017 were 3,443 and 4.14, respectively. The evaluation of the effect of water fluoridation as an environmental protective factor showed that the intervention by reducing the risk of dental caries could fall the DALY and DALY rates in the country by 14,971 and 18.73, respectively. In the period of 2005-2017, the DALY rate (per 100,000 people) attributable to ambient air PM2.5, tropospheric ozone, residential radon, and occupational risk factors rose that the result increases the importance of the preventive measures and controls of these risk factors. Conclusion: There was a considerable difference in the burden of disease attributed to each risk factor in various international studies as well as between national and international studies. The results of national studies on the burden of diseases attributable to environmental risk factors are considered to be more reliable and practical due to the application of more detailed data and conducting subnational evaluations; therefore, the strengthening and continuing these studies at the national and sub-national levels with regard to priorities, needs, and spatiotemporal trends using domestic reliable data and information are necessary and strictly recommended.
