The Effect of the COVID-19 Pandemic on Environmental Health (Two Sides of the Same Coin): A Systematic Review.

BACKGROUND: The outbreak of the COVID-19 pandemic in late 2019 has led to many changes such as reduced human activities and effects on the environment. There is no big picture of the effects of pandemics on the environment using related evidence. OBJECTIVES: This study was conducted to investigate the effect of the COVID-19 pandemic on environmental health. METHODS: A systematic search of English language studies was performed in major electronic databases; Web of Science, PubMed, Scopus, and Google scholar web search engine from December 2019 to February 2022. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) standard guidelines were used to follow up the review process. finally 58 articles entered the review procedure. RESULTS: The results of indicate a significant reduction of air pollutants and improved air quality. It improved the water quality of some rivers, canals, and seas during the lockdown of the COVID-19 pandemic. The effects of this disease on the environment cannot be fully described yet. CONCLUSION: In the short term, the amount of air, water, and coastal pollution has been reduced. few studies have examined the effects of pandemics on the environment in the long run, which paves the way for more researches.

Epidemiology and factors associated with COVID-19 outbreak-related deaths in patients admitted to medical centers of Mazandaran University of Medical Sciences.

BACKGROUND: The first case of COVID-19 was reported in Iran on February 19, 2020, in Qom. Since Mazandaran is one of the high-risk provinces with many patients and deaths, this study was conducted to investigate the epidemiological characteristics of COVID-19-related deaths in Mazandaran. MATERIALS AND METHODS: In this descriptive study, demographic information and clinical findings in patients who died following COVID-19 in the medical centers of Mazandaran University of Medical Sciences from February 8, 2020, to October 10, 2020, were extracted. Data were analyzed by using SPSS 21. Logistic regression was used to compare the data. P < 0.05 was considered as the significance level. RESULTS: Out of a total of 34,039 patients admitted during the 8 months, 2907 patients died. Of these, 1529 (52%) were male, and the rest were female. In terms of age, 10 cases in the age group of fewer than 15 years, 229 cases in the age group of 15-44 years, 864 patients in the age group of 45-64 years, and 1793 people in the age group of 65 years and over died. 2206 people (more than 75%) by personal visit referred to medical centers. The mortality rate was more than 8 cases per 100 hospitalized patients. Men were 16% more likely to die from COVID-19 than women. DISCUSSION AND CONCLUSION: Older adults over 65 have the highest incidence and death rate due to this disease. The incidence rate was higher in women, and the death rate was higher in men, which differs from the national pattern.

The Effect of Warm Footbath on the Quality of Sleep on Patients with Acute Coronary Syndrome in Cardiac Care Unit.

Introduction: This study aimed to determine the effect of warm footbath before bedtime on the quality of sleep on patients with acute Coronary Syndrome in Cardiac Care Unit. Methods: This study was conducted on 120 patients admitted to CCU at Mazandaran Heart Center and randomly divided into two groups of intervention and control. In the intervention group, warm footbath was performed after the second night in hospital before bed time by 41 C water for 20 minutes for three consecutive nights; in contrast, the control group did not receive anything of this sort. The next day, St Mary's Hospital Sleep Questionnaire was completed to evaluate sleep quality. Then, the obtained data were analyzed using SPSS software and Friedman, Wilcoxon exact statistical tests. Results: The quality of sleep in the first night of hospitalization was different from the third night after the intervention in both groups and the improvement process of sleep quality was observed in both groups. Most patients had moderate impairments (23-36), which had not changed during the intervention. In intervention groups, 8 patients had severe sleep disorders (greater than 37), which declined to 1 after three nights of intervention. While, in the control group this number fell from 10 patients with severe sleep disorders to 5. Warm footbath had a great positive impact on patients suffering from severe sleep disorders (P<0.05). Conclusion: Although warm footbath did not improve the quality of sleep in all patients, it reduced the number of patients who had severe sleep disturbances.
