The human coronavirus is a member of the Coronaviridae family and causes upper respiratory tract infections. Despite repeated severe epidemics and the lack of appropriate antiviral drugs, not much progress has been made on the epitope-based vaccine designed for HCoV. 

Methods & Materials:

The method of this study was to select the spike corona virus protein sequence from NCBI, retrieve the protein sequence and determine the T, B epitopes required to produce the chimer vaccine, evaluate the antigenicity and allergenicity and toxicity of the selected epitopes, respectively. Different servers were designed to configure the primary chimer composition of the epitope vaccine. Then, the chimer vaccine was evaluated in terms of structure and connectivity to B cells and MHCI and II compounds, and the two-dimensional structure and position of amino acids and bonds in the immunogenic model were studied, as well as the physicochemical and stability of the model vaccine by some other servers. Finally, it was tested for binding against HLA molecules using silico docking techniques to investigate the interaction with the epitope.

Ethical Considerations: 

All ethical principles are considered in this article. Participants were informed about the research objective and its implementation stages. They also made sure their information was confidential. The principles of the Helsinki Convention were also observed.

The results showed that the immunogenic construct created in terms of two-dimensional and three-dimensional structure and the position of amino acids and bonds in the model of immunogenic structure, toxicity and allergenicity and antigenicity were in good condition. And had stability (instability index 33.93) and favorable half-life and suitable physicochemical conditions.

In general, the immunogenic structure that was prepared in this research process could have a favorable interaction with some components of the immune system (HLA) in the docking process, which indicates the optimal identification of this structure by the humoral and cellular immune system and stimulation in In order to produce immunity in the body of the host, of course, more reliable proof of it requires clinical phase processes.

 The main purpose of this study was to compare the metacognitive beliefs of people with hypochondriasis Covid 19 and normal people.

Methods & Materials: 

In this research, the causal-comparative method has been used. The statistical population of the study included all people with hypochondriasis disorder Covid 19 in Arak, based on this, 30 people from the population with this disorder and 30 people from the normal population were selected by available sampling method and based on Age and education were matched. Data were collected based on the short form of the 1997 Wells Metacognition Questionnaire (MCQ-30). Multivariate analysis of variance was used to analyze the data.

Ethical Considerations: 

The present study has been registered with the code IR.IAU.ARAK.REC.1399.036 in the ethics committee of Islamic Azad University Arak branch. 

There was a significant difference between metacognitive beliefs in patients with hypochondriasis covid 19 and normal individuals (P<0.001). These patients were significantly different from normal individuals in the components of positive beliefs about worry, negative beliefs about thought control, self-awareness, cognitive uncertainty, and the need to control thoughts. And in the components of positive beliefs about anxiety, negative beliefs. They got higher scores on controlling thoughts and cognitive self but on the components of cognitive uncertainty and the need to control thoughts compared to normal people.

Hypochondriasis disorder causes many problems for the individual and the health system, so by recognizing the dysfunctional metacognitive beliefs of these patients, metacognitive therapy can be an effective treatment for this disorder.

Children with Attention Deficit Hyperactivity Disorder are a good target group for cognitive rehabilitation Because their behavioral problems, including inattention, impulsivity, and hyperactivity, have a specific cognitive and cerebral origin. This adaptation of behavior to cognitive function provides an opportunity to repair behavior by strengthening cognitive function. This study aimed to compare the effectiveness of cognitive rehabilitation based on virtual reality technology as a new method and classical cognitive rehabilitation in improving the executive functions of children with attention deficit hyperactivity disorder.

Methods & Materials: 

This research was a quasi-experimental study using a pre-test-post-test design with a control group. The statistical population included all children aged 7-12 years with Attention Deficit Hyperactivity Disorder in Tehran in 1398 who were selected by convenience sampling method and randomly divided into 3 groups of 12 people. In the pre-test stage, participants were assessed with the Attention Deficit Hyperactivity Disorder Rating Scale and the Computer Integrated Visual and Auditory Test (IVA-2). The first group received a virtual reality-based cognitive rehabilitation package and the second group received a Captain Log computer cognitive rehabilitation package, 12 sessions twice a week. No intervention was performed in the control group during this period. Post-tests were taken from all 3 groups after the intervention. Univariate analysis of covariance (ANCOVA) was used to analyze the data using SPSS software v. 26.

Ethical Considerations: 

This study was approved by the Research Ethics Committee of the Islamic Azad University, Central Tehran Branch (Code: IR.IAU.CTB.REC.1400.001). 

The results showed that both methods of cognitive rehabilitation intervention had a significant effect on cognitive functions (selective attention, sustained attention) of Attention deficit hyperactivity disorder (ADHD) children (P<0.01). But no significant difference was observed between the mean scores of selective attention and sustained attention in the first experimental group and the second experimental group (P>0.05). 

Virtual reality-based cognitive rehabilitation is as effective as classical cognitive rehabilitation on selective attention and sustained attention in children with ADHD. Virtual reality-based cognitive rehabilitation can be used as a new approach to rehabilitating this disorder.

The type of circadian rhythms is essential in maintaining physical and mental health and recovery from the disease. This study aimed to investigate the role of circadian rhythms on sleep quality and corona anxiety in men and women.

Methods & Materials: 

The present study is a descriptive comparative causal description. The statistical population included all 18-50 who participated in the survey online. People who completed the questionnaire online were selected for sampling. The research instruments included the circadian inventory rhythms Horne and Ostberg (1976), Petersburg Quality of Sleep Questionnaire (1989), and Alipour et al.’s (2020) Corona-related Anxiety Scale in the Iranian sample. Multivariate analysis of variance (MANOVA) and the Scheffe test were used to analyze the data.

Ethical Considerations: 

This study was registered with the Ethics Committee Razi University Technology Units Development Center at Institute for Psychoanalytic Studies (No.: 99133).

The results showed that the mean of mental and corona physical anxiety in women and men with evening type is higher than in other classes. Men and women in the evening type have a lower sleep quality than in the morning and middle types. The results also showed significant differences between the types regarding corona anxiety, sleep quality, and sex. The difference between the mean of the morning type and evening types’ mean was more than other differences between the means.

Individual differences in morning-evening types seem to play an essential role in the quality of sleep and the experience of corona anxiety

The research results show tobacco use increases cardiovascular and lung disorders or the probability of periodontitis in humans, while no definitive relations were yet confirmed. This study evaluates the relationship between periodontitis and tobacco use by panoramic radiography in Bandar Abbas City.

Methods & Materials: 

A total of 198 panoramic radiographs were classified into periapical healthy (n=99) and patient (n=99) groups. Radiologists assessed radiographs for periodontitis via Total Teeth Numbers (TTN), the quality and length of Root Filling Treatment (RFT), the number (NoRFT), and inadequate root filling treatment (RFTin), age, gender, the cigarette and hookah use, and dental debris. Data were analyzed by Chi-Square, t-test, and logistic regression.

Ethical Considerations: 

Due to the lack of therapeutic intervention and the preservation of patients’ characteristics, ethical considerations are not included in this study (Code: IR.HUMS.REC.1399.384)

Tobacco, hookah use, TTN, and RFTin were different (P<0.01) in groups, but cigarette smoking, debris, RFT, NoRFT, and age were not. Women in the periodontitis group showed high (P<0.01) in tobacco, hookah use, and RFTin, while no gender differences were observed in other parameters. The logistic regression results showed that based on the Odd Ratio NoRFT (39.7), RFTin (36.8), `hookah (8.1), tobacco (6.57), debris (3.62), smoking (3.59), RFT (1.4) and TTN (0.89) were the highest (P<0.01). At the same time, age and gender did not affect periapical tissues. 

Hokka, tobacco, and cigarette use negatively affected the periapical tissues, respectively. The decrease in TTN and increase in debris and RFT were probably the effects of tobacco smoking on the periapical tissues. Age and gender were not related to the periapical lesions.

Women are the central pillar of social development and the main axis of family health. Success, survival, and promotion of society depend on the health of women in society. Since Health Promotion lifestyle and psychological well-being are important determinants of health, this study was conducted to determine the Health Promotion lifestyle and psychological well-being in women attending the health centers of Arak City in 2019.

Methods & Materials:

 In this cross-sectional study, among women who attended health centers in Arak City, 221 women who met the inclusion criteria were included in the study by continuous sampling and the form of demographic information, health promoting lifestyle profile-Ii (HPLP-II), and Ryff Psychological well-being Questionnaire was completed. Data were described using descriptive statistics of frequency, frequency percentage, mean, standard deviation, and data analysis by analysis of variance, independent t-test, and regression using SPSS software v. 19.

Ethical Considerations: 

This study was approved by the Ethics Committee of Research Deputy of Iran University of Medical Sciences (Code: IR.IUMS.REC.1398.609).

 The mean health-promoting lifestyle in the study units was 135.96; the mean physical activity components were 16.31; The mean nutrition was 26.41, with the lowest and highest scores, respectively. The mean psychological well-being in the study units was 72.29. The mean components of purpose in life were 10.76, and the mean personal growth was 13.19, with the lowest and highest scores, respectively. Age, chronic diseases, employment, number of children, and alcohol consumption had a significant negative relationship with a health-promoting lifestyle, and a woman’s and her husband’s education had a significant positive relationship with a health-promoting lifestyle (P<0.05). Overall demographic variables predict as much as 13% of health-promoting lifestyles. Age, number of children, and chronic physical and psychological diseases had a significant negative relationship with psychological well-being and economic status. A woman’s and her husband’s education had a significant positive relationship with psychological well-being. Overall, demographic variables predict as much as 10% of psychological well-being. 

Considering that health-promoting lifestyle and psychological well-being are two critical determinants of health, studying these two indicators and the factors affecting them can help Intervention planning to promote women’s physical and mental health.
