Life in today's world is filled with stress and challenges, requiring individuals to develop skills to cope with crises. One such skill is resilience. This study aims to determine the correlation between hope and resilience among students at Khorramshahr University of Marine Science and Technology.

This research utilized a descriptive-correlational design. The study population consisted of all students enrolled at Khorramshahr University of Marine Science and Technology in 2021. A sample size of 200 participants was determined through simple random sampling. Data were collected using three questionnaires: a demographic questionnaire, Miller’s Hope Scale, and Connor’s Resilience Scale. The collected data were analyzed using SPSS version 24, employing descriptive statistics, analysis of variance, independent t-tests, and Pearson's correlation coefficient.

The mean and standard deviation for hope and resilience were 148.45±5.75 and 67.09±7.07, respectively. The results indicated a statistically significant relationship between the average resilience scores and marital status (P<0.05). Additionally, Pearson's correlation coefficient revealed a significant correlation between hope and resilience among students (P=0.03).

The findings suggest that both resilience and hope play crucial roles in the mental health of students. By fostering hope and resilience, it may be possible to enhance students' life satisfaction. Furthermore, hope serves as a psychological strength that contributes to increased resilience. Therefore, implementing educational programs, workshops, and establishing counseling and support groups can be effective intervention strategies to nurture hope among students.

 During a pandemic, in addition to a serious threat to the physical health of vulnerable people, the fear of disease and fear of death, along with everyday disturbances, causes healthy people to be involved with the anxiety and stress of the disease and suffer psychological disorders. In the meantime, healthcare workers and medical students are groups of people whose mental health status can be endangered by this virus. Therefore, the present study aimed to assess the relationship between perceived psychological stress and anxiety caused by COVID-19 in students and healthcare workers working at the Asadabad School of Medical Sciences.

During a descriptive-analytical study, 113 students and 85 health workers working at Asadabad School of Medical Sciences in 2019 were examined using a stratified sampling method with proportional allocation. The data collection tool included demographic information, Alipur Corona Disease Anxiety Scale (2018), and the 14-item version of Cohen's Perceived Stress Scale (1983). After collecting the data, they were analyzed using SPSS software (version 26). Spearman's correlation test and Mann-Whitney's non-parametric test with an alpha significance level of less than 0.05 were used to check the relationships and compare the data.

The overall mean scores of perceived psychological pressure of workers (22.25±9.29) and students (23.90±9.35) were close to the mean level, and the overall mean of COVID-19-induced anxiety in both groups was at a moderate level (workers: 16.36±10.85 and students: 15.24±10.15). Moreover, there was a positive and significant statistical relationship between perceived psychological pressure and COVID-19-induced anxiety in both groups of workers (r=0.55; P0.00) and students (r=0.37: P=0.00). Nonetheless, the comparison of the level of perceived psychological pressure of medical workers and students did not demonstrate a statistically significant difference between the two groups (u=4108.5; P=0.08). This comparison was not significant for the level of COVID-19-induced anxiety caused in the two groups (u=4582.5; P=0.58).

The results of the present study pointed out that both groups of medical workers and students experienced almost the same amount of psychological pressure and anxiety. Furthermore, with the increase in participants' level of COVID-19 anxiety, the perceived psychological pressure also increased and vice versa. Therefore, it is recommended that psychiatrists and psychologists be employed in COVID-19 centers, that free psychological counseling be provided to health-treatment workers and students with problems, and that workshops and retraining courses on resilience and problem-solving skills be held.

25(OH)D is decreased in the patients with end stage renal disease (ESRD). Some evidences are available showed that 25(OH)D measurement can reflected the serum levels of active form of vitamin D [1,25(OH)2D] in ESRD patients. The aim of this study was to assess the association of serum 25-hydroxyvitamin D levels with 1,25-dihydroxyvitamin D deficiency in end stage renal disease patients (1, 2). The hormones related to vitamin D are calcitonin and parathyroid hormone, all of which are involved in renal calcium reabsorption (3). Vitamin D production is stimulated by parathyroid hormone and decreased by calcium. Extrarenal synthesis of vitamin D occurs under the influence of cytokines and is essential for paracrine regulation and cell differentiation (4). Plasma concentrations of 1 and 25-hydroxyvitamin D (1,25 (OH) 2D) in plasma are constantly monitored by parathyroid hormone (PTH), serum calcium and phosphate, and fibroblast-like growth factor 23. Low levels of 1,25 (OH) 2D are observed even in the early stages of kidney failure. Decreased levels of 1,25 (OH) 2D are exacerbated by the progression of renal failure (5). Deficiency in the production of 1-alpha hydroxylase enzyme in renal failure is thought to be the main mechanism of this process. However, phosphate retention and FGF-23 have also been attributed to reduced synthesis of 1,25 (OH) 2D. However, phosphate retention and FGF-23 have also been attributed to reduced synthesis of 1,25 (OH) 2D. In addition, hyperphosphatemia, metabolic acidosis, and other uremic toxins may suppress 1-alpha hydroxylase activity and 1,25 (OH) 2D synthesis, but its effects in advanced stages of chronic kidney disease (CKD) such as stages 4 and 5 Reaches the maximum (6, 7). Due to the fact that studies have shown that replacing vitamin D deficiency with active drug forms D2 and D3 is more effective and potency than inactive forms of vitamin D, and these compounds suppress the increase of serum PTH and thus the side effects and pain. Therefore, the aim of this study was to investigate the relationship between serum levels of 25-hydroxyvitamin D (25 (OH) D) and deficiency of 1 and 25-hydroxyvitamin D (1,25 (OH) 2D) in patients. The final stage was kidney disease (ESRD).

This study is descriptive-analytical and cross-sectional. The study population included all patients with end-stage renal disease referred to the Panj Azar Educational and Medical Center in Gorgan during 2014. Based on the study of Urena et al. In 2011 (20) and estimating the correlation coefficient of 0.29 for the linear relationship between serum level of -25-hydroxyvitamin D with 1 and -25-hydroxyvitamin D in ESRD patients and the following relationship at the significant level of 0.05 and Test power was 80%, sample size was calculated to be 91 people. In this study, 88 ESRD patients referred to 5th Azar Hospital in Gorgan in 2014 were studied. After recording demographic data, the serum levels of 25(OH)D and 1,25(OH)2D and other laboratory parameters were measured. Collected data were analyzed by SPSS-18 statistical software and chi-square and t tests and Pearson’s correlation model. This study was approved by the ethics committee of Golestan University of Medical Sciences with ethics code IR.GOUMS.REC 31078693122416. Blood samples from all patients up to 10 cc for routine tests of patients with renal failure including CBC, Na, K, Ca, P, BUN, Cr, PTH and ALP and in the next step to measure serum level 25 - Hydroxyvitamin D as well as 1 and 25-hydroxyvitamin D were performed. Vitamin D was measured by ELISA method with a special kit. Serum levels of 25-hydroxyvitamin D less than 15-30 ng / ml were considered as insufficient vitamin D, values ​​less than 15 ng / ml were considered as vitamin D deficiency and high values ​​above 30 ng / ml were considered normal. And outside this range was considered abnormal. The range of normal values ​​of 1 and 25-hydroxyvitamin D was determined in a large study of 20-60 pg / ml (4). Inclusion criteria included end-stage renal disease and non-inclusion criteria were not receiving vitamin D supplements during the last month. The researcher asked all the patients included in the study about not taking vitamin D and if they did not take it, they entered the study. Dialysis adequacy factor is calculated by the formula KT / V, which was calculated monthly in the forms of dialysis patients in the 5 Azar Medical Center, and in fact, a number less than 1.5 was considered as the optimal dialysis adequacy. The sun-damaging factor was removed so that all samples were collected in one season, and all patients received normal community nutrition. The collected data were analyzed after coding and entry in SPSS software version 18. Mean, median, standard deviation and percentage were used to describe the data. If the serum levels of vitamin D were normal, t-test was used to compare the mean serum levels of vitamin D between groups (insufficient amounts, deficiency and normality of vitamin D). Chi-square test (2 χ) was used to compare the ratio of vitamin deficiency between groups and Pearson correlation test was used to compare numerical variables. If the data were not normal, non-parametric tests were used. The significance level of the tests was considered 0.05.

The mean age of patients was 56.1±14.1 years and 43.2% of them were male and 56.8% were female. 51.1% of patients were obese or overweight. The mean serum concentrations of 25(OH)D and 1,25(OH)2D were 23.3±16.7 and 147.3±49.2 ng/dl, respectively. Moreover, 51.1% of them had 25(OH)D deficiency, 44.3% insufficiency and 4.5% sufficiency. 1.1% of patients had 1,25(OH)2D deficiency and 98.9% had increased 1,25(OH)2D. 25(OH)D serum levels in ESRD patients were associated with 1,25(OH)2D serum levels (P=0.037). There was no association between vitamin D serum concentrations and studied variables (P>0.05).

The results of this study showed that 25(OH)D serum level had a negative and significant correlation with 1,25(OH)2D serum level.

From the point of view of Islam, the family has a special position and sanctity that cannot be compared with any other institution.

The aim of this study was determination of the relationship between fitness and posture alignment in blind and deaf children.
Material and

Sixteen blind, 30 deaf and 60 healthy children (6-12 years) were participated in this study. Physical fitness was examined with 3minute step test, sit ups, hand grip strength test, sit-and-reach and trunklifting. Spinal curvature was assessed with spinal mouse, and head and shoulder posture was assessed with photography. Pearson correlation test was used (α=0/05) for data analyzing.

Results of this study showed that there was relationship between the BMI and kyphosis, hand grip strength and FSP, Flexibility and uneven shoulder, flexibility and lordosis in blind children. In deaf children, there was relationship between the BMI and kyphosis, VO2 peak and scoliosis, uneven shoulder and FSP, muscle endurance and thoracic scoliosis and FHP, muscle strength and scoliosis, flexibility and uneven shoulder and FSP, trunk flexibility and kyphosis, scoliosis and FHP. In normal children, there was relationship between the hand grip strength, kyphosis, scoliosis and lordosis and between trunk flexibility lordosis and scoliosis.

The relationship between the Physical fitness and posture in blind and deaf children necessitates the attention to both physical fitness and corrective exercises in physical education programs in schools and guiding these children toward appropriate sporting activities.

Background and

Astigmatism is a common optical dysfunction, effective on various visual outcomes and one of the important criteria of refractive surgery. The aim of present study was to evaluate the correlation between refractive, corneal and residual astigmatism in refractive surgery candidates.

In this cross-sectional descriptive, analytical study, 200 patients referred to the Farabi hospital, Iran, for refractive surgery were enrolled. Refraction survey and topography were done to determine refractive, corneal and residual astigmatism for all of participants and statistical analyses were performed.

Overall, 400 eyes of 200 subjects with the average age of 28.2 ± 6.24 participated in this study. 62.7% of cases were women. According to spherical equivalent, 94.2% were myope, 3.3% were hyprope and 78.9% had refractive astigmatism more than 0.75 D. Mean spherical equivalent refractive errors was -3.59 ± 1.95 D in myopic group and 2.72 ± 0.97 D in hyperopic group; mean astigmatism was 1.97 ± 1.3 D in myopic and 1.3 ± 1.37 D in hyperopic group. The correlation ratio was (r = 0.223) between lenticular and refractive astigmatism (P < 0.001), (r = 0.111) between lenticular and corneal astigmatism (P = 0.027), and (r = 0.942) between refractive and corneal astigmatism (P < 0.001).

Significant correlations were found between refractive, corneal, and residual astigmatism; there was a strong correlation between corneal and refractive astigmatism; and 81% of the changes in refractive astigmatism could be justified with corneal astigmatism changes. Separating the type of astigmatism and determining its origin (cornea or lens) could be helpful for refractive surgery.
