Abstract
Background: Influenza is an acute respiratory disease caused by influenza virus. Influenza epidemics are reported every year and worldwide pandemics occur with varying frequencies. The majority of mortalities are due to underlying diseases and complications associated with influenza. In this study, we evaluated ten fatal cases caused by the established type A influenza (H1N1) infection in the 2009-2010 pandemic.
Materials and Methods: This mortality survey was compiled by a review of the deceased patients’ files. The assessed variables were demographic data, underlying diseases, secondary infections, delayed commencement of therapy, and non-medication. Collected data were analyzed by measures of central tendency and dispersion using SPSS software.
Results: In the ten deaths due to the established H1N1 virus, the median of age was 30 years and 90% of the cases had underlying diseases. Ninety percent of the deaths occurred during October and November and the rest took place in December and February.
Conclusion: The main cause of death was the delayed commencement of antiviral treatment. This emphasizes the importance of timely treatment in high risk patients. In flu pandemics, physicians should swiftly start specific therapy in at-risk groups to reduce the mortality rates.

Abstract
Background and Aim: In December 2019, the new coronavirus disease (COVID-19) was first identified in Wuhan, China, and then spread rapidly around the world, such that the World Health Organization reported it as a pandemic. This study aims to review the epidemiological findings, transmission methods, clinical manifestations, radiological symptoms, prognosis and treatment of COVID-19 in children, as well as the differences caused by the virus between children and adults.
Methods & Materials: The search was conducted in databases such as PubMod, Scopus, ScienceDirect and Google Scholar using the keywords “COVID-19”, “Coronavirus”, “Children”, and “Pandemic”.
Ethical Considerations: Ethical principles have been observed in accordance with the guidelines of the National Ethics Committee and the COPE regulations.
Results: Most of the data related to COVID-19 are related to the course of this disease in adults and related information for children is limited. Most findings suggested that the course of the disease is milder in children and the infection caused by the virus has a better prognosis in children. Due to the mild clinical symptoms in children, many of them are not diagnosed in the early stages of the infection. With the increase in the number of cases worldwide, the prevalence of this disease in children is certainly increasing.
Conclusion: COVID-19 has milder clinical symptoms and a better prognosis in children. Today, no vaccine or antiviral drug has been developed for this disease; hence, prevention is the best solution.

Abstract
Background and Aim So far, extensive research has been conducted on the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) virus and its disease in different regions of the world. The aim of these studies is to present practical findings and suggestions about more familiarity with the characteristics of this virus, including its structural and genetic characteristics, origin of genesis, evolution, genomic changes, biological cycle and pathological function, that can be used to adopt efficient strategies in controlling and treating the pandemic.
Methods & Materials In order to perform genomic analysis, the complete sequence of the desired coronaviruses with accession numbers obtained from GenBank or GISAID was stored from databases such as NCBI and BV-BRC, and then the sequences were aligned with Workbench CLC Main software. In the next step, the phylogenetic tree was drawn by Neighbor-Joining method with 1000 repetitions (bootstrap) by MEGA X software and FigTree version 1.4.4 was used to display the tree more clearly.
Ethical Considerations All ethical principles in writing this article have been observed according to the instructions of the National Ethics Committee and the COPE regulations.
Results In the current study, mutations and the effect they may have on transmissibility, pathogenicity and vaccine effectiveness, molecular features, epidemiology and the place of emergence of coronaviruses, focusing on variant of concern (VOC) including alpha (B.1.1.7), beta (B.1.351), gamma (P.1), delta (B.1.617.2) and omicron (B.1.1.529) are presented.
Conclusion The occurrence of mutations and continuous evolution have led to the rapid and simultaneous emergence of different variants, each of these changes can contribute to the escape of therapeutic methods such as neutralizing antibodies (Nab) and convalescent plasma, as well as reducing the effectiveness of vaccines. Therefore, increasing monitoring for documentation, understanding the spread of different lineages and more detailed study of these mutations in identifying variants and effectively dealing with them is of great importance.

Abstract
Introduction: The purpose of the "Health Communication" discussion plan, the most serious sparks of which were struck in the minds with the emergence of the COVID-19 pandemic in 2019, revealed the importance of paying attention to improving health communication more than ever. For this purpose, in the current study, the formulation of a conceptual model of health communication capacities in pandemic conditions was examined from the perspective of health system experts.
Methods: This research was conducted using a qualitative approach and the foundation's data theory method. Sampling was done with a purposeful snowball method, which included 20 communication and media professors and health professionals. Data collection was done through semi-structured interviews and document reviews based on the systematic approach of Strauss and Corbin (open, central, and selective coding), which includes causal conditions, central idea, context, mediating conditions (intervenor), strategies, and consequences of analysis. Validation was done through the review of participants and experts in the health system.
Results: The findings of the research in the grounded theory section show that the dimensions of the paradigm model include the central phenomenon: health communication (effective and informative communication), causal conditions: health communication harms (infodemic), the context of harms (widespread and popular media, lack of authority of the health unit, mass information, politicization), strategies (holding officials accountable, reliable sources and producing practical content, anxiety management, avoiding exaggeration of people's participation, teamwork and combination of experts, using the experiences of other countries) and consequences including (attracting trust and forming beneficial relationships) took place.
Conclusions: According to the dimensions achieved in presenting the model for improving health communication capacities in pandemic conditions in the country, it can be said that on the one hand, "transparency and immediacy of information" and the other hand, "empathy and trust between people and officials" in such More than one situation should be considered.

Abstract
Introduction: The growing increase in the elderly population requires more research to identify the health priorities of this group, especially in critical situations such as the COVID-19 pandemic. Therefore, the current study was conducted to determine the influential components of marital satisfaction and its relationship with lifestyle in Urmia City in 2021.
Methods: In this descriptive-analytical and cross-sectional correlational study, 220 married elderly living in Urmia were selected through cluster sampling. The Miler's life satisfaction and Haynes's marital satisfaction questionnaires were used in addition to the demographic questionnaire to collect data in this research. Data were analyzed using descriptive statistical tests (mean and standard deviation, frequency, and percentage) and analytical (Pearson correlation coefficients and multiple linear regression) at a significant level of P ≤ 0.05.
Results: A step-by-step multiple linear regression model also revealed that variables of lifestyle (ß = -0.364), age (ß = 0.425), number of children (ß = 0.143), occupation (ß = 0.425) and illness (ß = 3.608) - had the most considerable contribution in the sensitive prediction of marital satisfaction. The regression model excluded other demographic variables.
Conclusions: This study showed that lifestyle and demographic variables such as age, number of children, occupation, and illness have the greatest contribution in predicting marital satisfaction. Therefore, it seems necessary to design counseling services in comprehensive health centers for this group so that counselors can teach healthy lifestyles to older adults to improve marital relationships.
