Investigating the relationship between the anxiety of contracting corona virus and the symptoms of obsessive-compulsive disorder with the mediating role of mental confusion and emotion regulation in health care center employees

Introduction: anxiety caused by the Corona virus transmission are highly prevalent among medical staff, so this study aims to determine the relationship between the anxiety of affected by infectious diseases and the symptoms of obsessive-compulsive disorder with the mediating role of mental confusion and emotion regulation. MethodS and Materials: This study was carried out based on correlational method in the form of modeling of structural equations, in which 350 male and female employees working in the health and treatment centers of Neyshabur city were selected through available sampling. Data collection tools included Madsley Practical Obsession Scale, Corona Alipour Anxiety Questionnaire, Criver, Solly and Esomil's Deliberate and Automatic Disorientation Questionnaire, and Gross and John's Emotion Regulation Questionnaire. After completing the questionnaires, data analysis using Modeling of structural equations was done with Lisrel and SPSS softwares. Results: between the anxiety and obsessive symptoms with r = 0.576, between mental confusion and obsessive symptoms with r = 0.553, between mental confusion and anxiety with r = 0.481, There is a significant direct relationship at the level p>0.01. But between emotional regulation and obsessive symptoms with r = -0.643, between emotional regulation and anxiety with r = -0.495, between emotional regulation and mental confusion with r = -0.611 there is an inverse significant relationship. Also, the results showed the role of two mediating variables of mental confusion and emotional regulation in the relationship between corona anxiety and obsessive symptoms. Conclusion: The model of the relationship between the anxiety caused by the transmission of the corona virus and the symptoms of obsessive-compulsive disorder according to the mediation of mental disorientation and emotion regulation has a good fit that with the increase in the number of emotions and defeat in regulating one's emotions, the symptoms of obsessive-compulsive disorder and confusion mental health also increases in the treatment staff. According to these findings, it is expected that health managers and medical centers will pay special attention to the psychological well-being of the personnel working in different parts of this profession.

The human health risks assessment posed by the presence of heavy metals in the rice varieties available in the Neyshabur market.

The present study was designed to determine the levels of heavy metals (Cu, Pb, Ni, Cr, Zn, Mn, Cd, and Co), Mn, and As in Iranian-grown rice and imported rice consumed in Neyshabur City. For this research, 90 samples from 30 different brands widely consumed in this city were collected. The content of heavy metals and the health risks associated with their use were then studied. The study found that Zn (14.21mgkg-1) had the highest content in Iranian and imported rice varieties, whereas Cd (0.02mgkg-1) had the lowest value. The health risk assessment was also done in three scenarios and separately for two types of rice. The results showed that the total hazard quotient (i.e., THQ) was measured for all metals and all three scenarios, and for both types of rice, it is THQ > 1, which indicates the risk of non-carcinogenic in rice. The cancer risk for three scenarios and two types of imported andIranian rice is in the unsafe range for As (8.80× 10-4 to 7.00× 10-3),Ni (4.60 × 10-4 to 3.60 × 10-3) and Cr (2.20 × 10-4 to 1.90 × 10-3) and negligible for Pb (1.09 × 10-6 to 1.49 × 10-5) and Cd (7.83 × 10-6 to 8.20 × 10-5).

Trace element concentrations and associated human health risk assessment in canned tuna, city of Neyshabur, Iran

Seafood is considered a healthy and nutritious food, but the presence of toxic substances in such foods is a serious problem. The present study aimed to analyze the concentration of some toxic metals in seafood and evaluate their noncarcinogenic risks to consumers. Samples were digested according to the Association of Official Agricultural Chemists (AOAC) standard. The heavy metals concentration of Cd, Ni, Hg, Pb, and Sn in 30 canned tuna samples were determined using an inductively coupled plasma optical emission spectroscopy (ICP-OES). The mean concentrations of Cd, Ni, Sn, Pb, and Hg were 0.7, 0.49, 1.03, 0.31, and 0.12 µg g− 1, respectively. Based on these results, the concentrations of Cd, Sn, and Hg in samples met the required standards. However, the concentrations of Ni and Pb in some samples were higher than the permissible limits. The mean values of Sn, Ni, Pb, Hg, and Cd in samples followed a decreasing order. Since the values of the health risk index for these samples were lower than the HI and HRI risk threshold (<1), they can be consumed without any problems arising. Highlights The metal concentration was measured in the four most popular brands of canned fish sold in Neyshabur City, Iran. Some samples exceeded the maximum permissible level of nickel (Ni) and lead (Pb). A significant correlation was observed between Ni concentration with Pb and Hg concentrations and Pb concentration with Cd concentration. The values of the health risk index (HRI) for noncarcinogenic health risks were lower than 1. The calculated Hazard index (HI) for adult and child consumers was less than 1. The HI values were greater for children than for adults.

The epidemiology and treatment outcomes of COVID-19 patients admitted to an intensive care unit in an Iranian hospital in Neyshabur city.

The COVID-19 pandemic and the infection of numerous individuals from diverse societies have emerged as major global challenges. Given the limited resources in intensive care units, effective bed management and resource allocation require a deep understanding of the disease. This study aimed to assess the epidemiology and treatment outcomes of COVID-19 patients admitted to an intensive care unit in an Iranian hospital in Neyshabur city. This cross-sectional study was conducted on COVID-19 patients hospitalized in intensive care units in Razavi Khorasan, Iran in 2021. Census sampling was used to include all intensive care units. Of the initial 480 cases, 54 cases were excluded based on the exclusion criteria, leaving 426 cases for the study. Data were collected with the help of a data collection form that was designed by the researcher and its content validity and reliability were measured with Cronbach's alpha coefficient (α = 89%.). Data were analyzed with SPSS version 20 software. Descriptive and inferential statistics were used to analyze the data. Mean, standard deviation, and interquartile range indicators were used for descriptive statistics, and absolute frequency and relative frequency (percentage) were used to show numbers and ratios. The mean (SD) age of the patients was 66.33 (15.05) years, and 49.3% were female. The results showed that arterial blood oxygen saturation, respiratory rate, and Alzheimer's disease were significant variables for predicting mortality. Furthermore, arterial blood oxygen saturation, respiratory rate, and the need for transfusion of blood products were significant variables in predicting hospitalization and the risk of acute respiratory distress syndrome (ARDS). This study demonstrated that arterial blood oxygen saturation, respiratory rate, and Alzheimer's disease are crucial variables for predicting death. Furthermore, arterial blood oxygen saturation and respiratory rate are significant factors in predicting the risk of ARDS.

Identifying the Barriers to Performing Dispatcher-assisted Bystander Cardiopulmonary Resuscitation in Out-of-hospital Cardiac Arrest

Background: Bystander cardiopulmonary resuscitation (BCPR) is critical for the survival of patients with out-of-hospital cardiac arrest (OHCA). This study aims to identify barriers to performing dispatcher-assisted bystander cardiopulmonary resuscitation (DA-BCPR) in patients with OHCA. Materials and Methods: This cross-sectional study was conducted on bystanders of 151 patients with OHCA who received emergency medical services (EMS) from June 2022 to June 2023 in Neyshabur City, Iran. The study data were collected using a questionnaire and telephone interviews. Data were analyzed using the chi-square test and Fisher exact test. P&lt;0.05 was considered statistically significant for all tests. Analyses were done using R software, version 4.0.1. Results: Of 151 patients, 18.92% were less than 50 years old and 68.92% were male. In 69% of cases, the arrival time of EMS was less than 10 min, and 84.46% of patients received BCPR at the scene. The most common barrier to performing DA-BCPR was “not recognizing a cardiac arrest and how to perform cardiopulmonary resuscitation (CPR)” (41.48%). It was reported that 38.35% of the bystanders were familiar with CPR. There was a significant relationship between the bystanders’ familiarity with CPR and performing DA-BCPR (P&lt;0.01). Conclusion: The most common barrier to performing DA-BCPR on patients with OHCA is the lack of knowledge and skills in bystanders. Improving bystanders’ knowledge and educating them about cardiac arrest, CPR, and DA-BCPR is critical to help them improve outcomes for OHCA patients.

Predictors of sexual and reproductive health self-care based on demographic factors in adolescent girls.

Global access to sexual and reproductive health is an essential human right, especially to adolescent girls. For improvement sexual and reproductive self-care needs to determine the related factors on utilization and acceptance by adolescents. Therefore, the aim of this study was to examine the SRH self-care and its predictors among adolescent girls in Neyshabur city at Northeast of Iran. The present study was a cross-sectional correlational study performed on 265 girl students from 15 girls' high schools in Neyshabour, in Razavi Khorasan province, Northeastern Iran. The sampling method was multistage probability sampling. Data were collected using demographic information and female adolescents' sexual reproductive self-care scale. Data were analyzed using descriptive, frequency, percentage, mean, standard deviation, and ANOVA, Pearson correlation coefficient, and multiple linear regression model. The significant level was p<0.05 using SPSS16. The results of the present study showed that the mean score of the sexual reproductive health self-care was 61.23 of 100±10.5, it had a significantly relationship with fathers education high school [B=-7.241 CI: (-11.088 to-3.393)], diploma [B=-7.221 CI:-10.707 to-3.735] than academic. The rank of children birth in the family first [B=6.012 CI: (0.931-11.092)] second [B=4.436 CI: (1.437-8.309)] than third and above. Economic status of household Excellent [B=3.159 CI: (2.193-8.511)], Favorable [B=5.866 CI: (1.355-10.378)], relatively favorable [B=2.705 CI: (1.802-7.213)] than poor level economic. sexual and reproductive health is associated to father's education, the rank of children birth in the family, and economic status. So these variables will help to strategies and progress educational programs.

Comparison of the Prevalence of COVID-19 in Female Students based on Body Mass Index and Waist–Hip Ratio

Introduction: COVID19 is an acute respiratory syndrome that affects the immune system. Obesity can increase the risk of developing this disease. The aim of this study was to evaluate the prevalence of COVID-19 in female students based on their body mass index (BMI) and waist-hip ratio (WHR).&#x0D; Methods: 700 girl students aged 15-18 years in Neyshabur City, Iran were selected by simple random sampling and divided into two groups: the healthy (n=519) and Corona (n=181). The results were analyzed using non-parametric statistical tests of Mann-Whitney U Test, Spearman correlation coefficient and two-point string test at a significance level of p≥0.05.&#x0D; Results: In the healthy group, the mean of BMI was 21.09±3.4, WHR 0.77±0.07, and age 16.53±1 years and in the Corona group, the mean of BMI was 22.32±4.11, WHR 0.77±0.06 and age was 16.80±0.89 years, respectively. The results of the Mann-Whitney U test in the BMI of the two groups were significantly different (P = 0.001). Abdominal obesity was not significant in both groups (P = 0.469). There was a significant positive relationship between BMI and WHR (P = 0.00094). There was a significant relationship between BMI and Corona using the agreement coefficient with the two-point string test (P = 0.001). Also, the results of the Mann-Whitney U test showed that the resting heart rate of the two groups was significantly different (P = 0.026).&#x0D; Conclusion: The results of the present study showed that in adolescents, increasing BMI and resting heart rate increases the prevalence of Corona disease and abdominal obesity has no effect on corona virus infection. Therefore, due to the effect of exercise activities on losing weight and resting heart rate, the need to do these activities during quarantine is considered.

Heavy metal analysis in of indoor and outdoor dust extracts and cytotoxicity evaluation and inflammation factors on lung, gastric and skin cell lines

Dust particles (DPs) are one of the most important public health concerns in the urban environment. The presence of heavy metals (HMs) on the surface of DPs might increase the health risk of exposure to the DPs. Accordingly, The purpose of this study was to examine the content of HMs in the outdoor and indoor DPs in Neyshabur city and assess the cytotoxic effects of DPs exposure on lung, gastric, and skin cell lines. To this end, the city was divided into three areas, high-traffic, medium-traffic, and low-traffic (rural). The average concentration of the HMs in the indoor DPs were as follows, 655.5 μg g-1 for Zn, 114.6 μg g-1 for Cu, 77.7 μg g-1 for Cr, 108.6 μg g-1 for Ni, 52 μg g-1 for Pb, 12 μg g-1 for Co, and 3.3 μg g-1 for Cd, while the average concentration of Zn, Cu, Cr, Ni, Pb, Co, Cd in the outdoor DPs were 293.7 μg g-1, 200.6 μg g-1, 100.7 μg g-1, 68.4 μg g-1, 44.7 μg g-1, 18.6 μg g-1, 0.25 μg g-1, respectively. A higher concentration of HMs, as well as cytotoxicity, were revealed in the indoor samples compared to outdoor ones. The degree of cytotoxicity of DPs collected from high-traffic areas was higher than that of low and medium-traffic ones. In addition, treatment of AGS and L929 cells with indoor dust samples induced the expression level of inflammatory agents such as TNFα, IL6, and, CYP1A1 genes more than in outdoor dust samples (P < 0.05). Briefly, a higher level of HMs concentration and cytotoxicity effect on the given cell lines was observed in the samples taken from indoor environments and high-traffic areas.

Heavy metal concentrations and health risk assessment in urban soils of Neyshabur, Iran.

This study aimed to determine and analyze heavy metal pollution in the street dust of Neyshabur city of Iran. In this regard, the concentration of ten heavy metals, including Al, Fe, Mn, Zn, Cu, Cr, Ni, Pb, Co, and Cd, was measured at 60 street dust samples. The samples from Neyshabur city in three zones were collected, including high traffic, low traffic, and rural. Twenty samples in each area, 10-sample in summer and 10-sample in winter, were studied. The average concentration of the target heavy metals (mg kg-1) in the street dust samples was as follows: 50514.09 for Al, 42473.33 for Fe, 647.4 for Mn, 230.07 for Zn, 146.44 for Cu, 96.18 for Cr, 73.25 for Ni, 40.56 for Pb, 14.86 for Co, and 1.32 for Cd. Based on the findings, it can be concluded that non-carcinogenic risk assessment for all quantified heavy metals was less than the allowed values. In addition, the carcinogenic risk assessment of these metals indicated high carcinogenic-risk indexes through exposure to Cr for adults and exposure to Cr, Co, and Ni for children. As a consequence of this investigation, efforts to avoid the transmission of heavy metals in the environmental soil of Neyshabur city should be encouraged.

Metabolic Syndrome and Body Composition Among People Aged 50 Years and Over: Results from The Neyshabur Longitudinal Study on Ageing (NeLSA).

There are few studies regarding body composition and metabolic syndrome (MetS) association in older adults. To evaluate the association between MetS and body composition indices in a large-scale population of subjects with an age of 50 and up. This study was based on the data from Neyshabur Longitudinal Study on Ageing (NeLSA) in a total of 7462 people of Neyshabur city in IRAN. The best cut-off scores and AUC value of body composition variables for having association with likelihood of MetS were determined by using a receiver operating curve analysis. Each unit increase in the Waist/Hip ratio, the odds of having MetS increase 3-6 times (OR: 4.937, 95%CI: 3.930, 6.203 in men; OR: 3.322, 95%CI: 2.259, 4.884 in women). In addition, in the case of BMI (OR: 1.256, 95% Cl: 1.226, 1.286 in men; OR: 1.104, 95% Cl: 1.086, 1.121 in women) and BFM (OR: 1.119, 95% Cl: 1.105, 1.133 in men; OR: 1.050, 95% Cl: 1.041, 1.060 in women), the chance of having MetS increases with increasing these variables. Totally, BMI and BFM showed the best AUC values. The optimal cut-off values for BMI in men was 26.45 and in women was 27.35 and for BFM in men was 23.35 and in women was 26.85. These results suggest that adiposity measures such as BMI and BFM are associated with likelihood of having MetS in subjects with an age of 50 and up, and that avoiding high adiposity is important to prevent MetS incidence.

Background: The obesity crisis is one of the major public health issues in the 21st century, and depression, anxiety, and stress are the psychological factors that mediate obesity. Objectives: This research was conducted to evaluate the effectiveness of internet-based cognitive-behavioral therapy (ICBT) in reducing body mass index (BMI), stress, anxiety, and depression in overweight women via a virtual group. Methods: This randomized controlled trial study was conducted on three groups of the experiment, the waiting list, and the treatment-as-usual. It was done as single-phase, single-center, and double-blinded. The statistical population included all women with BMI ≥ 25 in Neyshabur city in 2019 - 2020. The research sample included 90 subjects randomly assigned to the groups. The therapeutic intervention was applied in the form of 42 ICBT sessions using a virtual WhatsApp group. The participants completed the Depression Anxiety Stress Scale (DASS), and their BMI was also calculated before and after the sessions. Results: The analysis of covariance indicated the significant effect of ICBT on the reduction of BMI compared to the usual treatment group and waiting list group [F (72, 2) = 15.54, P &lt; 0.0005; Partialη2 = 0.30]. However, it was not significant on the reduction of stress [F (72, 2) = 0.47, P = 0.63; Partialη2 = 0.01], anxiety [F (72, 2) = 0.49, P = 0.61; Partialη2 = 0.01], and depression [F (72, 2) = 0.06, P = 0.93; Partialη2 = 0.002]. Conclusions: The present study showed the direct effect of ICBT on the reduction of BMI like the treatment-as-usual for obesity. However, these sessions could not reduce the participants’ stress, anxiety, and depression.

Isolation of Probiotic Lactobacilli from Indigenous Yogurt and Cheese and Their Antagonistic Roles Against Foodborne Pathogens

Background: Probiotic bacteria are one of the useful dietary supplements for human health. The main reason for selecting probiotics is the lack of prolonged side effects. Objectives: This study aimed to isolate lactobacilli from traditional yogurt and cheese samples collected in Neyshabur city, Khorasan Razavi, Iran, and to characterize them using specific biochemical and molecular assays. Methods: The probiotic potency of bacteria was tested by resistance to acid, bile, NaCl, and organic acid production. Moreover, the antagonistic effects of the isolates were investigated against enteric pathogenic bacteria using the well diffusion method. Bacteriocin production was also investigated using the microtiter plate assay. Results: Four Lactobacillus spp. with &gt; 99% homology to L. reuteri, L. plantarum, and L. acidophilus, were isolated with probiotic potency. The quantitative measurements used in the study with the statistical analysis resulted in the interpretation of good effects against Clostridium perfringens, Salmonella typhi, Staphylococcus aureus, and Listeria monocytogenes. Our isolates exhibited bile salt hydrolase activity, excellent NaCl and acid tolerance (pH = 3), and bacteriocin production. Conclusions: Our results showed that Lactobacillus strains isolated from Neyshabur traditional cheese could be considered good potential probiotic strains and had more antagonistic activity against human pathogens when compared to other samples. Their antibacterial activity was associated with both bacteriocin and organic acids production, but they should be further investigated for their human health benefits.

Evaluation of heavy metal concentrations in black tea and infusions in Neyshabur city and estimating health risk to consumers

ABSTRACT Heavy metal pollution is one of the environmental problems and one of the critical concerns of food hygiene. Consumption of tea as a pleasant drink and food habit is common among Iranians.The presence of these metals in tea can be an essential source of contamination in food.This study aimed to investigate the levels of lead, chromium, nickel, cadmium, aluminium, and arsenic in samples of dry black tea and Infusionsin the market of Neyshabur in 2019.Samples were digested with nitric acid and perchloric acid, and the concentration of the desired metals was read by the spectrometric method.All experiments were performed in 3 replications.Then, the Provisional Tolerable Daily index (PTDI) and Hazard Quotient (HQ) levels of heavy metal intakes were calculated to estimate the health hazard for consumers.The Mean concentrations of Pb, Cr, Ni, As,Al, and Cd in the tea leavesand Infusions were 1.96, 3.05, 3.68, 0.048, 2.195, 0.03 mg/kg and 0.07, 0.17, 0.88, 0.03, 0.53, 0.003 mg/kg, respectively.The results also showed that the target hazard quotient (THQ) for Cr and Alis more than one. In the samples of dry tea and their Infusions, concentrations ofCrand Alwere exceeded from Iran’s Ministry of Health and WHO guidelines. The two elements of Ni and Pb are more than the Iranian National Standards Organisation’sinstructions.HQ values for chromium and aluminium obtainedhigher than one, which indicatedadverse effectson tea consumers’ health. Therefore, continuous monitoringis essential to determine the toxic metals’concentrationsin tea samples.

Impact of water resources management on area under cultivation level and agricultural production efficiency (Case Study: Villages of Zebarkhan district of Neyshabur city)

The amount of water consumed in the agricultural sector in Iran is higher than the global average and this necessitates more attention to proper water management in this sector. Due to the climatic conditions of Iran, the average rainfall in most areas is lower than global rainfall. That is to say, the water issue is one of Iran's most important concerns or the greatest challenge for the people of this land. Examining the current agricultural situation indicates that despite the increased agricultural production potential due to the lack of a proper management system, optimal utilization of available resources has not become possible and droughts and reduced rainfall and increasing population followed reduce the amount of water consumed in the agricultural sector. The present study investigates the impact of agricultural water resources management on the economic development of rural settlements (Case study: Villages of Zebarkhan district of Neyshabur city). This research is applied in terms of purpose and in terms of descriptive and analytical method and library and field methods have been used for data collection. According to the results of the present study and data analysis regarding the amount of water consumed in the study area, it was observed that the amount of water consumed per hectare for all crops in modern management lands was less than the fields where managed by the traditional way. This suggests that modern science-based scientific management has played a key role in reducing the loss of water resources within the scope of this study, and in contrast, water loss in farms that are managed in traditional ways is so high. Also, regarding the production efficiency in the study area, the results showed that the production efficiency per hectare for all crops was significantly higher than that under traditional management. This rate varied between 25 to 57.1%.

Effects of Rhythmic and Simple Auditory Stimulations on Learning the Timing of Sequential Motor Task in Children With DCD

Introduction: Children and adolescents with Developmental Coordination Disorder (DCD) usually fail to understand spatial awareness and motor timing. The present study assessed Rhythmic Auditory Stimulations (RAS) and Simple Auditory Stimulations (SAS) to facilitate the learning of timing in sequential motor task and recorded the results of their relative and absolute timing errors. Materials and Methods: 56 male students aged 9-12 years with DCD in Neyshabur city were selected by diagnosing with the following tools: Teacher Motor Inventory, Parental Developmental Coordination Disorder Questionnaire, Movement Assessment Battery for Children-Second (MABC-2 movement test), spatial-visual memory assessment, intelligence assessment, RT test, and biopsychological health status evaluation. Then, they were divided into RAS, SAS, control group 1 (visual), and control group 2. Moreover, a pretest score was performed. Next, the training protocol was presented in 10 blocks of 5 attempts and the acquisition test was performed. Finally, the retention and transfer tests were performed after 48 hours and 10 minutes, respectively. Results: Based on the obtained results, a significant difference was observed between the visual stimulation group and the RAS and SAS groups in relative and absolute timing components (P≤0.05). However, no significant difference was reported between the rhythmic, SAS, and visual-auditory stimulation groups in relative and absolute timing variables (P˃0.05). Conclusion: Finally, no significant difference was observed between the RAS and simple stimulations although the graphs displayed the effect of the first stimulation more than that of the second one.
