Background: Brucellosis is the most significant and common bacterial zoonosis and is recognized as a re-emerging and neglected disease. Tackling zoonosis is very important for the health and the economy. One Health is an approach characterized by the integration of human and animal health, plants, and ecosystems and encourages joining local, national, and global multidisciplinary efforts to achieve optimal levels of health and collaboration among different disciplines to address complex health problems. Objectives: The present study aimed to review published scientific literature related to the use of the One Health approach to tackle human brucellosis. Methods: Web of Science (WoS), PubMed, Scopus, The Cochrane Library, and Embase databases were searched from inception until 30 January 2020. The reference lists of all relevant papers were hand-searched. Two authors extracted data from published studies independently. The Joanna Briggs Institute tool was used to assess the quality of studies. Results: Of 2297 studies, 10 studies were deemed eligible, which were conducted between 2013 and 2019. Studies were performed in Uganda, Malta, Serbia, Greece, Mongolia, Azerbaijan, Israel, India, Ethiopia, and the USA. All studies suggested that brucellosis is still a major public health problem and that the most important aspect of the One Health approach is the interdependence of humans, ecosystems, and animals .Some studies have focused on livestock vaccination as the most effective way to prevent disease, and others have focused on the biology of Brucella infection and its transmission patterns. Some studies have pointed to the effectiveness of the One Health approach in all the phases of disease management as well as to its role in reducing health costs. Conclusion: The success of the approach depends on the willingness of the decision-makers to implement the necessary policies. Due to the heterogeneity of current practices, and organizations involved in One Health approach-based programs, it will be incomplete without proper planning. To better implement the approach, strategies should be appraised and disseminated by experts and relevant stakeholders.

Mothers who take care of their disabled children usually suffer from several problems, such as physical, psychological, and social problems. The disability of children can also directly impress the quality of their mothers’ lives. This study is going to check out how the disability of children affects the quality of life of the mothers. This study was conducted to compare the quality of life and resilience of mothers with disabled and typically developed children in Fasa, Iran. The subjects of this cross-sectional study were 240 mothers (120 mothers having disabled children and 120 mothers with typically developed children) referring to Fasa State Health Centers and Fasa State Welfare Office. They were randomly selected and included in the study. All samples were collected by the convenience sampling method. The data were collected by using the World Health Organization Quality-of-Life Scale (WHOQOL-BREF) and the Connor-Davidson Resilience Scale (CD-RISC). The collected data were then analyzed by the SPSS (v.22) software. The results of the descriptive statistics, Chi-square, independent t-test, and Pearson correlation coefficient were at a significant value of P < 0.05. The mean score of quality of life of mothers with disabled children on physical, psychological, social, and environmental domains was lower than that of mothers with neurotypically and statistically significant (p < 0.05); however, the mean scores on the resilience of mothers in both groups were not significantly different (p = 0.43). The results of the linear regression analysis showed that, having a disabled child (P < 0.001, t = 10.141), level of education (P < 0.001, t = 2.031), and resilience (P < 0.001, t = 8.205) affect the quality of life. The lower the education level is, the lower the quality of life. And higher resilience increases the quality of life. The quality of life of mothers with disabled children was lower compared to mothers with typically developed children, but there was no difference between mothers' resiliency in these two groups. These results suggest the necessity to provide supportive and therapeutic programs for improving the quality of life of mothers with disabled children.

Academic motivation is one of the indices of success in scientific activities. Therefore, the goal of the present research is to predict academic motivation based on variables of personality traits, academic self-efficacy, academic alienation, and social support in students studying in different fields of paramedicine. The research was correlation-descriptive in which 183 paramedical university students in the academic year of 2019-2020 were selected by a two-stage cluster random sampling method, studying in the Kermanshah University of Medical Sciences. The data were collected through the Vallerand Academic Motivation questionnaire, NEO Personality Inventory Test, Sherer Self-Efficacy questionnaire, Fleming Social Support questionnaire, and Johnson Academic Alienation, and the collected data were analyzed (Pearson correlation coefficient and multiple regression) using SPSS V.22 software. The results showed that personality traits of extroversion ($\beta =0.255,p<0.01$ ), openness to experience ($\beta =0.185,p<0.01$ ), conscientiousness ($\beta =0.136,p<0.01$ ), and self-efficacy could predict academic motivation, significantly; but neuroticism ($\beta =-0.188,p<0.05$ ), and academic alienation ($\beta =-0.111,p<0.05$ ) reversely related to academic motivation. Self-efficacy ($\beta =0.121,p<0.05$ ) could significantly predict academic motivation. There was also a significant relationship between social support and academic motivation. The results of the research illustrated that some of the personality traits and self-efficacy had a positive role in predicting academic motivation among paramedical students, and neuroticism and alienation had a reverse negative role in academic motivation. Therefore, in order to promote the academic level of students, it is necessary to improve the harmful effects of self-efficacy and some personality traits that improve better learning performance and quality.

Sex work is a growing phenomenon triggered by a number of causes. The current study uses a qualitative method to investigate the reasons why women participate in sex work in Tehran. The statistical population consisted of all female sex workers in Tehran, Iran, from which 22 individuals were chosen via snowball sampling. In-depth interviews were conducted for data gathering, and traditional content analysis was used for data analysis. Graneheim and Lundman's method was utilized to evaluate the data, and Guba and Lincoln's criteria were employed to determine the research's strength and transferability. The results of the data analysis were divided into five categories (or themes) and 19 subcategories. The categories were familial instability, societal pressure, consumerism, social insecurity, and a meek and inefficient personality. Sex work may be avoided by raising women's social status, providing greater economic assistance, making society safer, particularly in workplaces, improving intra-family connections, boosting self-esteem and self-efficacy, and teaching them how to deal with life's issues.

The highly infectious novel coronavirus (COVID-19), officially SARS-CoV-2, was discovered in Wuhan, China, and quickly spread to the rest of the world in 2020. Frontline workers had frequent interactions with COVID-19-infected and -uninfected patients. Therefore, the study’s overarching goal is to investigate the experiences of frontline healthcare professionals in dealing with the COVID-19 health emergency. The study used a qualitative research approach with a phenomenological research design. Using a purposeful sampling approach, the researcher collected data from 24 participants. The MAXQDA program was used to analyze the data, and followed Collaizzi’s 7-step technique. All ethical standards were met to perform the study. Four main themes and ten subthemes were derived from the 24 in-depth interviews. The key themes were emotional suffering, intense physical pressure, social connection deterioration, and the inability to manage family obligations. Extensive social, emotional, and organizational aid is necessary to assist individuals in dealing with this unprecedented health crisis. Furthermore, the government and non-governmental organizations must work together to come up with the right policies to limit the COVID-19 burden on frontline health professionals.

Burnout is a job-related syndrome that is common among university staff, and it is caused by various factors. The purpose of this study was to investigate the prevalence of burnout and its relationship with capital types among university staff in Tehran, Iran. A cross-sectional descriptive-analytical design was used in which 420 staff were randomly sampled from the Iran University of Medical Sciences. For data collection, the researchers used the Burnout Inventory of Maslach and Jackson and Capital Types Questionnaire. The data were entered into SPSS software (Version 22) and analyzed by descriptive and inferential statistics and regressions. The mean burnout of staff was 84.42, and 45.9% of them had high burnout. A significant relationship was found among capital types, work experience, gender, education, and burnout. Multiple linear regressions also showed that independent variables estimated about 32% of the variance of the dependent variable, social capital, gender, and work experience, contributed more to explaining and predicting burnout index. Regarding the relationship between burnout and capital types (economic, cultural, and social), it is necessary to increase capital by increasing cultural activities, staff's knowledge level, income levels, informal groups, and finally, strengthening interpersonal relationships among staff.
