Background: Environmental characteristics, as well as the quality of health care services provided to older adults group, are among significant determinants of elderly quality of life. The present study was done to assess the quality of services delivered to elderly residents in nursing homes located in Tabriz, Iran in 2019. Materials & Methods: This cross-sectional study was conducted on the elderly living in nursing homes in Tabriz, Iran, of whom 74 residents met the inclusion criteria and were included. The researchers referred to the nursing homes and recruited the participants with regard to the inclusion and exclusion criteria. Results: Out of the 74 older adults, 35 and 39 cases were respectively male and female. The largest age group (43.2%) was related to those between 60 and 69 years old. Also, 71.6% of the elderly had been residing in nursing homes for 6-20 months. The rate of service quality in terms of the medical, psychological, welfare, and social domains was 66%, 48%, 68%, and 65%, respectively. Besides, no significant relationship was observed between demographic variables and total scores of service quality (P>0.05). Conclusion: Paying attention to psychological services, including providing counseling and social work services, adapting the centers, and creating recreational departments can lead to an increase in psychological quality and ultimately, overall service quality.

Background: Due to the pollution of drinking water resources and increasing consumer concerns and awareness about unhealthy drinking water, the urgent need for communities to have access to and produce safe water is felt more than ever, so in recent years the use of Point-of-entry (POE) and point-of-use (POU) filters (known as Household water treatment devices in Iran) in urban and rural communities of Iran, it has become very popular. In this regard, the purpose of this study was to investigate the causes of households in Sari, Mazandaran Province to use POU/POE treatment devices. Methods: This descriptive cross-sectional study was conducted in the fall of 2020 and using an electronic questionnaire to investigate the causes of the tendency of people in Sari to use POU/POE treatment devices. The number of participants in the study was 117 households that were selected according to the simple random sampling method. Results: The results of the present study showed that 73.5% of the surveyed households used the municipal tap water for drinking and 23.1% of the households applied the POU/POE treatment devices. The most common reason for dissatisfaction with urban water was related to the formation of sediments inside the pipe, kettle and water heaters. Conclusion: This study revealed that 23.1% of respondents used POU/POE water treatment devices because of low quality of municipal drinking water. About 17.9% of respondents are distrustful of municipal water system, which was mostly due to the high salt content and scaling of municipal drinking water in Sari.

Background: Understanding the knowledge and performance status of young girls regarding dysmenorrhea can be an initial step towards the future health planning for this group. This study aimed to determine the knowledge and practice of female students about dysmenorrhea. Methods: In this descriptive cross-sectional study, 315 female students were randomly selected. Data collection form included two parts. The first part consisted of questions regarding demographic characteristics and field of study, and the second part was knowledge and practice questionnaire. The scores were compared in terms of study variable. Results: Prevalence rate of dysmenorrhea was 75.2% and the most frequent symptoms was aggression and anger (49.3%). Of total, 15.6% had good knowledge. The level of knowledge was significantly associated with field of study and dysmenorrhea. The midwifery students had the highest mean level of knowledge. The mean score of knowledge in students who had experienced dysmenorrhea was higher than girls who had not experienced dysmenorrhea (P-value = 0.031). There were no significant differences of practice scores in terms of study variable. Conclusion: This study revealed a high prevalence of dysmenorrhea during menstrual period among female students. However, the study subjects had insufficient knowledge and moderate practice to reduce menstrual pain. It is recommended that more counseling education to be extended for female students to help them cope with the dysmenorrhea.

Background: Sexual satisfaction was one of the primary issues in marital life, but there are always factors that affect this satisfaction and affect the personal and social well-being of families. This study was aimed to investigate factors that may decrease couples' sexual satisfaction through a qualitative research. Methods: This study was a qualitative content analysis research. Purposeful sampling was used and after in-depth and open-ended interviews with 12 couples (12 female and 12 male), their experiences were analyzed through a thematic method. Results: Findings revealed that the reasons of sexual satisfaction reductions include personal deficits (cognitive distortions and inattention), interpersonal conflicts (interpersonal interference, weak interpersonal communication skills), and socioeconomic challenges (Fear of being labeled, economic shortages, and lack of skilled interveners). Conclusion: This qualitative research clarified some socio-cultural factors contributing to sexual satisfaction. The findings may have implication in the area of programming and planning for family health.

Background: Insulin serves an important role in brain metabolism, and insulin resistance and subsequent diabetes mellitus type 2 (DM2) can give rise to dysfunction of brain metabolism. This study aimed to test the hypothesis of association of late onset Alzheimer’s disease (AD) with DM2 in an Iranian population. Methods: In this case-control study, 243 subjects including 81 patients with late onset AD and 162 healthy controls were recruited. The frequency of DM were compared in AD patients with non-AD counterparts. Results: The prevalence of diabetes in AD and control patients was 27% and 9%, respectively. (OR = 3.94, 95% confidence interval: 1.89-8.22). After adjustment for age and gender, there was a significant association between DM2 and AD (OR = 3.7, 95% confidence interval: 1.73-8.00). Conclusion: The evidence from the present study suggested that DM2 was associated with AD in an Iranian population. Further longitudinal studies are warranted to confirm this finding.

Background: Topical anesthesia (TA) may accompany with more discomfort for some patients during cataract surgery. We aimed to evaluate the potential factors that can be used for predicting patient’s cooperation during phacoemulsification surgery under TA. Methods: One hundred sixty consecutive cases that were candidate for phacoemulsification surgery enrolled in this prospective study. Patient characteristics including sex, age, place of residence (urban or rural), education level (literate and illiterate) and physical examination variables including visual acuity in logarithm of minimum angle of resolution (LogMAR), reaction to eye drop, and cooperation during tonometry before surgery were evaluated. Patient cooperation during surgery was classified into successful (good and satisfactory) or failed (weak) cooperation. The two groups were compared in terms of baseline and clinical examination variables. Results: In this study, 103(64.4%) cases showed a good or satisfactory cooperation, and others had a weak cooperation. There was no association between patient cooperation during surgery and sex (P-value = 0.2), age (P-value = 0.7), place of residence (P-value = 0.3) and education level (P-value = 0.3). The successful group showed a higher rate of non-reaction to eye drop (P-value = 0.0001), good cooperation during tonometry (P-value = 0.0001), non-reaction to press on lacrimal sac (P-value = 0.0001), and lower visual acuity (P-value = 0.045). In the multivariate logistic regression model, non-reaction to eye drop (OR = 66.4), good and satisfactory cooperation during tonometry (OR = 21.2, OR = 7.2, respectively) compared to weak cooperation, lower LogMAR of visual acuity (OR = 7) were significantly associated with the success of TA. Conclusion: This study showed that some ocular examination tests before surgery including visual acuity, reaction to eye drop, cooperation during tonometry and reaction to press on the lacrimal sac can predict patient cooperation during phacoemulsification surgery under TA.

Background: Dyes are one of the most important pollutants found in the sewage of many industries, including; textile, printing, wood and paper industries, tanning, cosmetics and are often toxic, carcinogenic, mutagenic and non-biodegradable.This study aimed to investigate the removal of Basic Blue41 (BB41) by the oxidation process by using laccase in presence of ABTS mediator. Methods: The present study is an experimental in vitro study that investigated the main and interaction effects of three variables of pH, mediator concentration and laccase activity in three levels on BB41 removal efficiency by Response Surface Methodology (RSM), based on BoxBehnken design. Results: According to the results of the dye removal experiments, in the solution pH of 5, 0.2 mM of ABTS and the 0.2 U mL of laccase, BB41 was not observed in the tested sample solution and the final solution was completely colorless. Also, the statistical analysis of the data obtained from the experiments and the results of the analysis of variance showed that the model was statistically significant (P-value < 0.0001) and could reliably predict BB41 removal efficiency by laccase enzyme. Conclusion: This study found that laccase enzyme can be used to remove BB41 dye from aqueous solutions under optimum conditions designed by RSM.
背景:染料是许多工业污水中最重要的污染物之一，包括;纺织、印刷、木材和造纸工业、制革、化妆品等往往具有毒性、致癌性、诱变性和不可生物降解性。研究了漆酶在ABTS介质存在下对碱性蓝41 (BB41)的氧化去除效果。方法:基于BoxBehnken设计，采用响应面法(Response Surface Methodology, RSM)研究了pH、介质浓度和漆酶活性三个变量在三个水平上对BB41去除率的主效应和互作效应。结果:脱色实验结果显示，在溶液pH为5、ABTS为0.2 mM、漆酶为0.2 U mL的条件下，被测样品溶液中未观察到BB41，最终溶液完全无色。对实验数据和方差分析结果进行统计分析，发现该模型具有统计学意义(p值< 0.0001)，能够可靠地预测漆酶对BB41的去除效率。结论:本研究发现漆酶可以在RSM设计的最佳条件下去除BB41染料。

Background: Today, the hospital's priority is to attract and retain customers. Recent research has shown that the provided quality of services can influence customer reuse, loyalty, trust and satisfaction. The purpose of this study was to investigate the relationship between service quality and loyalty, trust and satisfaction of patients in health and medical centers of Guilan University of Medical Sciences through structural equation modeling. Methods: The present study was conducted on 384 people referred to Guilan University of Medical Sciences. Service quality was assessed using a questionnaire on 5 dimensions of infrastructure, space, object, interaction and process quality. The validity of the research instrument was assessed by factor analysis and its reliability was estimated by Cronbach's alpha coefficient. The conceptual model of research was tested through structural equation technique in SmartPLS software. Results: Infrastructure (r = 0.51), object (r = 0.2), atmosphere (r = 0.11), interaction (r = 0.09), and process quality (r = 0.14) had direct and significant impact on satisfaction. Satisfaction as a mediator variable was also positively influenced trust (r = and loyalty. Conclusion: The results of this study revealed that Infrastructure quality followed by object quality had greatest impact on satisfaction.

Background: Mushroom is one of the sources for protein supply, and it has taken into consideration among most countries in the world due to its rich medicinal features. Nowadays, due to the mechanization of traditional methods and quality control of products, it is possible to evaluate the quality of mushrooms with the help of image processing techniques. Methods: In this study, image processing systems were used to determine the appearance quality of mushrooms. Using the properties of color, area, weight, and volume obtained from data mining techniques, artificial neural networks and fuzzy logic system mushroom quality was evaluated. Results: A total of 250 images in three categories of defective, moderate were assessed. The correct detection rate by the image processing system was 95.6%. Conclusion: The results of this study showed the optimum performance of image processing systems for assessing the quality of mushrooms. The superiority of image processing systems compared to traditional method can be observed in the quality of increased efficiency and high accuracy, as well as the reduction of costs and destructive effects in the production and packaging of food products.
