Abstract
The COVID-19 outbreak has led to increasing global concerns about infection control. Amid this pandemic, dentistry could be considered as one of the most high-risk medical sectors for health workers due to the high exposure to patients infected with this deadly virus.After the decline of the steep prevalence of COVID -19 cases, the dental associations have allowed dental offices to reopen under special circumstances by taking the necessary precautions and following the prescribed guidelines to keep both the dentists and their patients safe and healthy during the treatment.
The aim of this review is to present a policy to manage and facilitate the dental procedures in the dental practice routine amid coronavirus by focusing on the patients’ risk level in order to keep the possibility of COVID -19 transmission to a minimum.

Abstract
According to recent studies, oral lesions associated with COVID-19, manifests in various forms which may be as inaugural symptoms for the onset of the disease. However, further investigations are needed to confirm their probable characteristic role in diagnosis of COVID-19. It should be also noted that any oral manifestation in COVID-19 must be considered to avoid neglecting oral changes with more lasting destructive effects such as necrotizing periodontal lesions.

Abstract
Decreased life expectancy is considered as a key indicator of human development. Obviously, the increase in mortality, especially in vulnerable groups such as older people, leads to a major disruption in the human development of countries. On the other hand, the destructive social and economic effects of COVID-19 on human life further reduce their life expectancy. Therefore, it is suggested that policymakers and health managers make appropriate decisions such as timely vaccination of older people, future treatment measures, and appropriate behavioral changes to control the disease and improve life expectancy among older people during the COVID-19 pandemic.

Abstract
Background and Objective: Children’s dental fear is one of the most important challenges that pediatric dentistry faces. Several factors play an important role in children’s dental fear. Home quarantine, changes in routine life and economic disadvantages have resulted in emotional changes in parents and children during COVID-19 pandemic. The aim of this study is to evaluate the levels of children’s dental fear, parental anxiety and their possible correlation during the COVID-19 pandemic.
Material and Methods: The present cross-sectional study comprised one hundred and four children aged 6-12-year-old and their parents. The level of parental anxiety was evaluated using Spielberger state-trait anxiety inventory. CFSS-DS (Children Fear Schedule Survey-Dental Subscale) questionnaire assessed the child’s dental fear. Independent t-test, ANOVA and Pearson correlation coefficient were used for data analysis.
Results: There were significant correlations between the level of parent’s state and trait anxiety and child’s dental fear (respectively P value=0.009 and P value=0.000). However girls showed insignificant higher levels of dental fear compared with boys (P value=0.175), children younger than 9 years old and children with a previous dental treatment had significantly higher dental fear scores (respectively P value=0.006 and P value=0.002). Age, gender and level of education did not show a significant effect on the level of parental anxiety (respectively P value=0.630, P value=0.874 and P value=0.198).
Conclusion: The study has resulted in a significant correlation between parental state-trait anxiety and children’s dental fear.

Abstract
Background and Objective: Since December 2019, the widespread outbreak of COVID-19 has led to a major public health issue worldwide. With the spread of the COVID-19 pandemic, a series of ethically challenging issues arose that put pressure on healthcare systems around the world. This narrative review aims to comprehensively review the literature focusing on ethical challenges and coping strategies about issues related to the healthcare system and social issues during the COVID-19 pandemic.
Material and Methods: This narrative review was conducted via international databases including PubMed/MEDLINE, Web of Science, and Scopus using keywords extracted from medical subject headings such as "COVID-19", "2019-nCoV disease", "2019 novel coronavirus infection", "Ethics", "Bioethical Issues", "Morals", "Coping Skills", "Coping Skill", "Coping Strategies", and "Coping Strategy" from December 2019 to January 2022.
Results: In general, ethical issues during the COVID-19 pandemic can be divided into two categories: 1) issues related to the healthcare system and 2) social issues. Issues related to the healthcare system can be divided into two categories: 1) lack of resources, equipment and facilities, and manpower, and 2) problems in patient care such as triage and informed consent. Social issues can be divided into four categories: 1) community engagement, 2) crisis management capacity in remote rural communities, 3) discrimination and health equity, and 4) vaccination. Coping with ethical challenges in crises such as COVID-19 requires changing health empowerment policies and strategies based on evidence-based research. On the other hand, overcome on these challenges requires interdisciplinary collaboration and fast efficient decisions.
Conclusion: Overall, the present study introduced ethical challenges and coping strategies during the COVID 19 pandemic. The experience gained from this pandemic can be considered by managers and policymakers of health care systems for coping with ethical challenges.

Abstract
Vitamin A is fat-soluble compounds of retinoid derivate, consisting of retinol, retinal, and retinyl esters. Vitamin A also affects cell growth and differentiation, playing a critical role in the normal formation and function of the heart, lungs, kidneys, and other organs. According to the role of vitamin A in enhancing immune function, it is known as an anti-inflammatory agent. Also, vitamin A supplementation by reducing morbidity and mortality in different infectious diseases, such as measles, diarrheal disease, measles-related pneumonia, human immunodeficiency virus infection, and malaria considered as a crucial factor against infection. So vitamin A deficiency can be life-threatening, because of impairing the response to infection and significant risk of development of severe respiratory infections in infants and young children. In this paper, we have discussed the effects of vitamin A in modulating immune responses in viral infections and the direct effects of this vitamin on viral replication by comparing its role during different types of viral infections.

Abstract
Background and Objectives: High workload, insufficient resources, and many stressors in the workplace have led to the imposition of physical and psychological pressures on nurses, which exposes them to death anxiety (DA). This systematic review aimed to assess the DA and factors associated with its in nurses during the COVID-19 pandemic.
Material and Methods: An extensive search was conducted on Scopus, PubMed, Web of Science, Iranmedex, and Scientific Information Database (SID) databases via keywords such asincluding "Death", "Death Anxiety", "Nurses", and "COVID-19", from December 2019 to November 10, 2021.
Results: 818 nurses were enrolled in four papers. The mean age and work experience of nurses Nurses’ mean age and work experiences were 31.21 (SD=5.43) and 7.60 (SD=6.73) years, respectively. The mean DA of nurses during the COVID-19 pandemic was 7.30 (SD=2.23). Also, 31.05% of nurses had a high level of DADA level during the COVID-19 pandemic. Age, sex, work experience, working hours per week, childbearing, several patients needing end‑of‑life care, direct participation in resuscitation operations, cases of direct participation in resuscitation operations, cases of patient death, depression, mental health status, and life satisfaction were influential factors in DA nurses during the COVID-19 pandemic.
Conclusion: Thus, nursing policymakers should pay special attention to these factors related to the use of nurses' health maintenance and promotion programs to increase the quality of nursing care for COVID-19 patients. Also, it is recommended that psychological and communication support be provided to nurses during the COVID-19 pandemic.

Background: Severely contagious, a beta coronavirus (COVID-19) has spread worldwide since December 2019, a life-threatening disease that leads to high mortality.
Methods: This study had 200 cases referred and admitted to 5th Azar Hospital in May and June 2020. Treatment started based on signs and symptoms and confirming positive CT scan findings. RT-PCR test is done for all of them. Patients are categorized due to age, underlying diseases, CT scan findings, and mortality.
Results: Diabetes mellitus (DM) was the most frequent underlying disease (35%), following hypertension (23.5%) and cardiovascular problems (9.5%). Although the severity of CT scan findings within the expired patients’ group was more than survived, the relation was insignificant (P=0.247). The mean age of cases who died was at least ten years more than survived. There was a mortality risk of 5.9 folds in cardiovascular disease (CVD) patients comparing patients free of CVD.
Conclusion: In dealing with involved COVID-19 patients considering their age and co-morbidities will help manage earlier and pay more attention to these cases.

Abstract
It seems necessary to understand the association of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which causes coronavirus disease 2019 (COVID-19), with its entering bronchoalveolar and brain cells, which have a high concentration of angiotensin-converting enzyme 2 (ACE2). Although the virus infects healthy people, the rate of infection and mortality is higher and significant in vulnerable people, such as drug users and addicts who have acute and chronic respiratory disease. It also places a heavy economic burden on families and societies around the world. Thus, researchers are aiming to provide prevention and treatment strategies to people at risk. The purpose of the present study was to collect studies on the rate of infection with coronavirus in people who abuse drugs. Besides, the role of the ACE2 receptor as a key factor in coronavirus infectivity in these people was investigated. Our narrative review on the relationship between COVID-19 and opioid abuse and smoking, with consideration of ACE2's role, contains original and human studies. According to the results of the current study, those who smoke or are dependent on opioids are much more likely to experience COVID-19-related respiratory side effects or even pass away.

Abstract
Background: Severe coronavirus infections may lead to long-term effects, such as persistent lung dysfunction and residual involvement. This study aimed to evaluate pulmonary function tests (PFT) and chest computed tomography (CT) scans of severe COVID-19 intensive care unit (ICU) survivors one year after discharge.
Methods: A cohort study was conducted, assessing spirometry and chest CT scans in patients with severe COVID-19 admitted to the ICU. Patients with pre-existing lung disease were excluded. Initial laboratory tests, clinical information, and medication (antivirals and corticosteroids) were reported in patients with and without fibrosis on chest CTs.
Results: Thirty patients (57% female) with a mean (SD) age of 50 (13.5) years were included. Initial pulmonary involvement had a mean score of 16 (±4), with ground-glass opacification (GGO) observed in all patients, consolidation in 88%, and pneumomediastinum in 10% of patients. One-year chest CT scans revealed mild fibrotic changes in 70% of patients, presenting as a fibrotic band (47%) or a fibrotic band with GGO (23%). Patients with fibrosis had lower serum albumin levels, lower platelet counts, and were older. One-year follow-up spirometry showed that 73% had normal results, 20% had mild obstruction, and 7% exhibited a hyperreactive airway pattern. Spirometry parameters did not significantly differ between the fibrosis and non-fibrosis groups.
Conclusion: Most patients who survived severe COVID-19 infection showed significant improvement in one-year follow-up chest CT scans, and their PFT was not severely impaired. Importantly, our findings indicate no association between the severity of initial lung involvement, medication use, and follow-up chest CT results.

Abstract
Background: End-Stage Renal Disease (ESRD) patients under maintenance hemodialysis are at higher risk for COVID-19 and severe outcomes. This study aimed to investigate the association between ESRD patients who underwent maintenance hemodialysis at 5th Azar and Sayad Shirazi Hospital in Golestan Province in 2019 and their risk of contracting and experiencing severe outcomes from COVID-19. Furthermore, this study aimed to provide insights into the epidemic status of COVID-19 in this specific population, contributing to better insight into the unique challenges faced by ESRD patients on hemodialysis during the pandemic.
Methods: This retrospective descriptive cross-sectional study was performed on patients who underwent maintenance hemodialysis. The diagnosis was made based on diagnostic criteria and COVID-19 PCR test. Medical information of all participants was collected. Medical information including clinical, laboratory, and radiological data as well as morbidity and mortality were collected and analyzed by experts. Statistical analysis was performed using SPSS version 21. Normality was evaluated using Shapiro-Wilk test and comparison between groups was analyzed using student T-test and Mann-Whitney U tests (p <0.05).
Results: The highest radiological view was related to the ground glass view with 46.7% and Linear Opacities with 26.7%. Most patients (86.6%) were discharged and four of them (13.4%) passed away. WBC, creatinine, and age were significantly associated with ESRD patients’ mortality (p <0.05). The patients who passed away were old and had higher levels of WBC and creatinine (p > 0.05). No significant difference was observed between the age and BMI of passed away and discharged patients. None of the laboratory parameters in the two groups of passed away and discharged patients with COVID-19 showed a significant difference (p> 0.05). Patients with COVID-19 who had a history of diabetes and hypertension, clinical symptoms, such as cough (p=0.049), weakness, and lethargy (p=0.05), indicated a significant difference in mortality compared to the group that was discharged (p <0.05).
Conclusion: ESRD patients who underwent hemodialysis due to their underlying problems and the crowded environment of dialysis wards more than the general population are at risk of getting COVID-19.
