Background & objectives: The rapid spread of COVID-19 has recently become a worldwide health challenge. Coping with the highly contagious outbreak of COVID-19 requires preventive measures and self-care behaviors in the first instance. To this end, the use of techniques and methods of coping, disease prevention as well as management, lifestyle, education and use of health items and providing self-care instructions can prevent further spread of the disease. The aim of this study was to determine the prioritization of self-care indicators in the prevention of Covid-19 in Ardabil province, which is one of the foci of this disease. Methods: This descriptive-field survey was conducted from the beginning of Covid-19 outbreak (March 1998 to January 1999). The sample size consisted of 120 people who were selected using the available snowball sampling method. Data analysis was performed using TOPSIS analysis software and formulation in Excel software based on weighting with entropy algorithm and prioritization with TOPSIS algorithm. Results: The results of this study showed the Sub-indics of increasing awareness of people about the prevalence of infection with proximity with coefficient (CLi +) of 0.8673, washing hands with soap and water or disinfecting with alcohol-based solution with proximity coefficient (CLi +) of 0.9391, electronicization of most activities Employees' work with a coefficient of closeness (CLi +) of 0.8687, observing a safe distance (1.5 meters) from people who cough and sneeze with a coefficient of closeness (CLi +) of 0.8277, avoiding any gatherings with a coefficient of closeness (CLi +) 0.9276, as the most important indicators among self-care methods in Ardabil province . Conclusion: This study was a proposed method to assist health care providers in making decisions and selecting the COVID-19 self-care model in Ardabil province.

Background & objectives: The Integrated Health System (SIB) is the latest electronic health record system in Iran, officially began in Iran in March 2016, with the goal of integrating health information and providing health services. This study aimed to design a model for establishment of the electronic health record in family physician program of Guilan university of medical sciences. Method: The research method was mixed method. Fifteen organizational and academic experts in the fields of family physician program and information technology were interviewed through purposive sampling using qualitative content analysis with conventional approach. Having identified the important components and respective dimensions in the initial conceptual model, the primary questionnaire was developed and submitted to the experts for their approval. Then, the final Likert-scale researcher-made questionnaire was extracted. Its content validity index was calculated by the experts and the reliability of the questionnaire was assessed through Cronbach’s alpha. The questionnaire was sent to 453 members of the healthcare team for being completed. Through analysing data by SPSS and LISREL, the final model was extracted using the specialized statistical techniques of exploratory and confirmatory factor analyses. Results: The model was presented with eight factors of attitudinal and behavioural, supervision and managerial, individual factors of users, interactions and teamwork, organizational, technical, systemic and job stability which can explain over 63 percent of the variance of the variables of electronic health record-based family physician program. The highest and lowest impacts on the proposed model came from the managerial and supervisory (0.85) and the job stability components, respectively (0.45). Conclusion: Establishing an electronic health record in the family physician program with the aim of providing good quality services and lower costs, is influenced by various factors that by strengthening the positive aspects and removing barriers in the identified factors, it is possible to institutionalize and use it more practically in order to solve health problems.

Background & objectives: The World Health Organization has introduced health literacy as one of the most important determinants of health which in turn can affect the quantity and quality of sexual relationship and sexual and marital satisfaction of individuals. Therefore, this study was conducted to determine the relationship between health literacy and marital and sexual satisfaction in women referring to health centers in Ardabil. Methods: This is a cross-sectional descriptive-correlational study. The statistical population was all women of reproductive age who referred to Ardabil health centers. Finally, 380 eligible women were selected using cluster sampling. To collect data, three questionnaires of the health literacy of the urban population of Iran (Helia), Enrich Marital Satisfaction Questionnaire and Hudson Sexual Satisfaction Questionnaire were used to collect the data. Data analysis was performed using SPSS-21 software and descriptive and analytical statistics were used to present the results. Results: The mean score of health literacy was 64.34 in the range of 33 to 165, the mean score of marital satisfaction was 142.84 in the range of 47 to 235, and the mean score of sexual satisfaction was 94.71 in the range of 25 to 175. There was a significant relationship between health literacy and age, marriage age, number of deliveries, type of delivery, education and occupation. There was a significant and direct relationship between health literacy and sexual satisfaction and there was a significant inverse relationship between marital satisfaction and sexual satisfaction. That is, it decreased with the increase of another. Conclusion: The results of this study showed that health literacy was low among women of reproductive age. This indicates the need to pay attention to the issue of health literacy in the women's community, especially in marital issues. Therefore, special attention and planning should be done in these subjects and the factors affecting them

Background & objectives: Weaning of children depends on several factors, recognizing each of these factors will be effective in adopting strategies to prevent abrupt cessation of breastfeeding. The aim of this study was to investigate the method of complete weaning of children and the factors affecting it in mothers with children aged 30-36 months in Kerman. Methods : In this cross-sectional study, 802 urban and rural mothers with children aged 30 to 36 months were selected by stratified random sampling. A breastfeeding pattern questionnaire with 75 to 98% Cronbach's alpha was used to collect data. Data analysis was performed using SPSS-21 software. Results: The average age of the mothers was 31.41±5.5, most of who had a university degree (45.2%) and were housewives (81.4%). In this study, complete weaning was gradual in 39% of children. The mean duration of gradual cessation of lactation was 21 days. 66.5% of mothers had obtained information in this regard. 58.2% of mothers made changes in their children's nutrition program. 46.7% of mothers considered a program (such as traveling, buying toys and going to park) for psychological support of their child. Conclusion: Mothers need specialized training in the process of weaning their children to complete the gradually weaning process for mothers and children without the use of various drugs or chemicals, with minimal possible physical or psychological damage.

Background & objectives: Safety control of traditional raw milk cheese such as Pot cheese is of special importance. Although enterococci can play beneficial probiotic or technological properties in cheese and their use in food is the subject of debate due to evidence of pathogenicity and antibiotic resistance. Method: In the present study, after isolation and morphological and biochemical identification of enterococci isolated from 50 samples of traditional Pot cheeses in West Azerbaijan province, the antibacterial properties of the isolates were determined by well diffusion method and the resistance pattern to 12 common clinical antibiotics was evaluated using disk diffusion method. The hemolytic properties of the isolates were also investigated. Results: The results showed the presence of enterococci in 74% of the Pot cheese samples. Among the identified species, Enterococcus faecalis and Enterococcus faecium had the highest frequency with 44.7% and 37.2%, respectively. The highest inhibitory effects of isolates were recorded for Listeria monocytogenes (83.7%). Studies showed that over 80% of isolates were sensitive to eight common clinical antibiotics, including vancomycin. Also, all enterococcus isolates lacked hemolysis activity. Conclusions: This study showed that traditional jar cheese is a rich source of Enterococcus bacteria with antimicrobial activity and high sensetive to common antibiotics such as vancomycin. If more safety aspects are studied and other probiotic properties are evaluated, these isolates can be used as a source of native probiotic bacteria in other fermented products. Conflict of interest: None declared.

Background & objectives: Nowadays, according to membrane-based filtration processes; the use of substances such as antiscalants that prevents the formation of deposits during the treatment process, is very important from industrial point of view. This study aimed to synthesize styrene-maleic anhydride copolymer (PSMA) using the radical polymerization method and to investigate the factors and parameters affecting its use in reverse osmosis membrane for removal of TDS from the Persian Gulf water sample. Methods: The present study was performed in laboratory scale to investigate the efficiency of synthetic antiscalants, in batch and fundamental-applied forms, as well as on a semi-industrial scale using reverse osmosis (RO) membrane system. Then, to evaluate its performance on the electrical conductivity (EC), total dissolved solids (TDS), flow flux, and membrane fouling in the reverse osmosis system, the effect of parameters such as pH and antiscalant concentration on increasing membrane efficiency and effectiveness were investigated. Results: The results showed that by adding antiscalant to the reverse osmosis system, the EC and TDS of the sample can be reduced in the range of 99.5-8.98% and 97.98-2.7%, respectively, so that in the study period, which was 1 hour, less performance reduction was observed in reverse osmosis membranes than in the absence of antiscalant. Also, the concentration of synthetic antiscalant up to 5 mg/L increased the efficiency, but had a small effect in higher amounts. Increasing the pH also had an adverse effect on efficiency of the reverse osmosis system and by increasing the pH from 7 to 9, the system efficiency decreased and higher TDS scores of 265.5 mg/L and 382.5 mg/L were observed in the treated effluent output, respectively. According to ANOVA statistical analysis and Prob> F values of 0.0004, the data were confirmed to be consistent. Also, a good match between the actual results and the predicted results of the software was confirmed and a logical relationship was obtained between the predicted and experimental regression coefficients. Conclusion: According to the results and by determining the optimal values of the studied parameters with a concentration of 5 mg/L antiscalants and at a pH of 7, the use of synthetic antiscalant increased the treatment efficiency using a reverse osmosis system. This material, by increasing the life of the membrane and preventing the formation of deposits on the reverse osmosis membrane, increased the time of use of this system and higher treatment efficiency was achieved in the reverse osmosis system in the presence of this anti-fouling.

Then, to evaluate its performance on the electrical conductivity (EC), total dissolved solids (TDS), flow flux, and membrane fouling in the reverse osmosis system, the effect of parameters such as pH and antiscalant concentration on increasing membrane efficiency and effectiveness were investigated. Results: The results showed that by adding antiscalant to the reverse osmosis system, the EC and TDS of the sample can be reduced in the range of 99.5-8.98% and 97.98-2.7%, respectively, so that in the study period, which was 1 hour, less performance reduction was observed in reverse osmosis membranes than in the absence of antiscalant. Also, the concentration of synthetic antiscalant up to 5 mg/L increased the efficiency, but had a small effect in higher amounts. Increasing the pH also had an adverse effect on efficiency of the reverse osmosis system and by increasing the pH from 7 to 9, the system efficiency decreased and higher TDS scores of 265.5 mg/L and 382.5 mg/L were observed in the treated effluent output, respectively. According to ANOVA statistical analysis and Prob> F values of 0.0004, the data were confirmed to be consistent. Also, a good match between the actual results and the predicted results of the software was confirmed and a logical relationship was obtained between the predicted and experimental regression coefficients. Conclusion: According to the results and by determining the optimal values of the studied parameters with a concentration of 5 mg/L antiscalants and at a pH of 7, the use of synthetic antiscalant increased the treatment efficiency using a reverse osmosis system. This material, by increasing the life of the membrane and preventing the formation of deposits on the reverse osmosis membrane, increased the time of use of this system and higher treatment efficiency was achieved in the reverse osmosis system in the presence of this anti-fouling.","PeriodicalId":15954,"journal":{"name":"Journal of Health","volume":"101 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76276492","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Background & objectives: Recently, fitness (bodyweight workout), kickboxing and TRX training have become very popular. The aim of the present study was to determine the effect of a period of fitness-kickboxing and fitness-TRX training on some anthropometric indices and cardiovascular risk factors in overweight women. Methods: Forty overweight women were randomly divided into three groups. The control group included fitness training and the experimental group included fitness training with kickboxing and fitness training with TRX. Subjects performed the training for two months (3 sessions per week). Then, on two occasions (before the beginning of the period and 48 hours after the end of the experimental period), anthropometric indices (using body composition analyzer) and blood samples (to measure blood lipid profile) were measured. For analyzing data, paired sample t-test and one-way analysis variance with the significant level of p <0.05 were used. Results: There was a significant difference between body weight ( p =0.001), BFM ( p =0.009), BMI ( p =0.0001), %BF ( p =0.037), WHR ( p =0.024) and also total cholesterol ( p =0.011) in fitness group, a significant difference between BFM ( p =0.012), %BF ( p =0.003) and WHR ( p =0.002) and also total cholesterol ( p =0.009), HDL ( p =0.016) and LDL ( p =0.0001) in fitness-kickboxing group and a significant difference between body weight ( p =0.0001), BFM ( p =0.001), BMI ( p =0.0001), %BF ( p =0.001), WHR ( p =0.0001) and also total cholesterol ( p =0.001) and LDL ( p =0.004) in fitness-TRX in the pre-and post-test. Furthermore, there was a significant difference between %BF ( p =0.003) and also HDL ( p = 0.021) and LDL ( p =0.0001) in three groups after a period of training. Conclusion: All three trainings somehow influenced anthropometric indexes and cardiovascular risk factors in overweight women. With the comparison of the three groups, it can be concluded that fitness training is more effective on decreasing %BF and LDL, fitness-kickboxing on decreasing %BF and increasing HDL as well as fitness-TRX training on reducing LDL.
