Osteoarthritis is an advanced degenerative process that causes irreversible loss of articular cartilage and it is characterized by joint pain and its dysfunction. The purpose of the present study was to investigate the effect of regular aerobic training and hyaluronic acid on cardiac tissue Wnt signaling pathway in experimental model of knee OA.

42 male rats were divided into 6 groups (7 in each group): 1) control, 2) patient, 3) salin, 4) HA,5) exercise and 6) exercise + HA. First, OA model was induced. Then, rats performed 5 days running on the treadmill for 5 weeks in the training group. Hyaluronic acid was injected intra-articularly. After 12 to 14 hours of fasting and 72 hours after the last training session, cardiac tissue sampling was performed for β-catenin and Glycogen synthase kinase-3 (GSK-3β) analysis. Expression of theβ-catenin and GSK-3βgenes in cardiac tissue were analyzed by RT-PCR. Data analysis was performed using one-way ANOVA, if there was a significant difference, Tukey’s post hoc test was used (P <0.05).

Induction of OA in rats led to a significant increase in β-catenin gene as well as a significant decrease in cardiac tissue GSK3 gene compared to healthy control group. The results also showed that regular aerobic training, hyaluronic acid injection and a combination of both treatments resulted in a decrease in the β-catenin gene and an increase in the cardiac tissue GSK3 gene compared to in the OA group rats.
Discussion and

Regular aerobic training in combination with hyaluronic acid by reducing β-catenin expression and increasing cardiac tissue GSK-3β gene expression may exert its protective effect, which may be prevent heart disease in the experimental model of knee osteoarthritis.

Primary Congenital Hypothyroidism is one of the most common endocrine diseases and it is one of the important and preventable causes of mental retardation. Determining the cause of this disease is very important and it can be very helpful in treatment and preventive proceduers. In the present study, this cause was investigated among children referred to Birjand Nuclear Medicine Center.

This descriptive-analytical study used the information in the files of children referred to Birjand Nuclear Medical Center that all of them had initial TSH levels higher than normal (TSH≥10mU / L). For some of the children referred, their TSH levels یreturned to normal after three years and they were in the transient hypothyroid group. After examining the rest of the children by an endocrinologist and nuclear medicine specialist, children with permanent defects were divided into two groups: thyroid dysfunction (dysgenesis) and thyroid hormone (dyshormonogenesis) and dysgenesis were divided in ectopic subgroups of Hypoplasia - Aplasia and agenesis. Patients’ information such as age, gender, family history and location were also collected.The cause of this disease was analyzed separately through patient information by Fisher statistical test.

By examining 80 children, 13 of them (16.25%) had their TSH levels return to normal after three years and their thyroid was transient. Among the permanent causes, ectopia with 24 girls (64.7%) and 10 boys (35.3%) had the highest frequency; moreover, hypoplasia or aplasia with 8 children had the lowest frequency. Among the children studied, the number of ectopic thyroid girls was more than boys. 52.5% of these children lived in urban areas and 48.5% of them lived in rural areas.

The most common cause of congenital hypothyroidism among the referral children is impaired complete or partial development of the thyroid gland, or impaired thyroid placement in the fetus.

Pregnancy is one of the most important and dangerous periods in the life of the mother and fetus. Maternal health or illness during this period affects not only the quality of life but also the health of the fetus and mother. Therefore, this study aimed to investigate the effect of pregnancy education on the health index of infants and the process of childbirth in pregnant mothers.

This study of double-blind clinical trial was conducted on 187 pregnant women referred to the pregnancy clinic of Shohada Ghaen Educational and Medical Center in 2018. The sample was randomly selected and it was randomly divided into twogroups of experimental and control. The experimental group took part in preparation classes for child birth during 8 sessions of 1.5 hours. Moreover, the control group received the usual prenatal care. To collect data, an individual information questionnaire, a physiological index record sheet, a partographic form, and a scale were used to weigh the baby. Data analysis was performed through statistical experiments of Key and Square test, independent t-test and ManWittney using SPSS statistical software (version 16).

In the study of health indexes of infants, statistical results showed that there was no significant statistical difference between the two groups in birth weight, head circumference, height of the infant and Apgar in the first and fifth minutes. The duration of labor showed that the length of the first stage was 184.92± 13 in the experimental group and it was 252.58±14 in the control group, which is statistically significant (P = 0.002). However, there was no significant difference between the second and third stage in two groups.

Pregnancy classes reduce the duration of childbirth. Thus, it is recommended that these classes be more extensively organized in the Pregnancy and Childbirth Care Centers.

The prevalence of corona virus and its psychological consequences is one of the most important human social events in the 21st century that nurses are faced with the psychological consequences. The aim of this study was to investigate the relationship between coping strategies, disturbance tolerance and psychological hardiness with corona virus anxiety in nurses in Kermanshah.

The present study is a descriptive correlational study. To select the sample size according to Morgan table, 169 people were selected by cluster random sampling technique from nurses of Kermanshah University of Medical Sciences. Lazarus and Folkman coping strategies questionnaires, Simmons and Gaher (2005) turbulence tolerance and psychological hardiness of Kiamarsi et al. (2004) and Corona anxiety scale of Alipour et al. (2019) were answered by those nurses who were willing to cooperate in the study.

The results of the analysis showed that the regression model used is significant (F = 13.43) and this model with a coefficient of determination of 0.36 has the ability to explain the relationship between variables. Multiple correlation between variables was 0.39 (R = 0.39).
Discussion and

It can be concluded that coping strategies, tolerance of turmoil and psychological toughness are effective factors related to corona virus anxiety that this point can be considered in health centers. According to the obtained results, it is suggested that during the outbreak of emerging and epidemic diseases to reduce corona anxiety in nurses, coping strategies, psychological toughness and tolerance of confusion for applying them more in their personal lives. It should be considered by the managers and officials of the Ministry of Health in advance.

Safe care is one of the main concerns in the care of patients with COVID-19; therefore, providing safe care can play an important role in promoting patient health. The aim of this study was to compare the quality of safe nursing care in corona and non-corona wards.

The present study is a cross-sectional descriptive-analytical study in which nurses safe care delivering in corona and non corona wards of Baqiyatallah Hospital has been compared in 1399. Sampling was done by census and the statistical population included all nurses working in corona and non-corona wards. The questionnaires were completed by the head nurses using two questionnaires of demographic information of nurses and Rashvand et al.

The nurse’s performance in patient care was moderate in corona and non-corona wards. There was no significant difference in different dimensions of quality of care (nursing skills, mental safety, physical needs and teamwork) in covid and non-covid wards (P <0.05).
Discussion and

Despite the contagious disease and fear of infection, nurses work in all conditions. On the other hand, due to the average quality of safe care in coronary and non-coronary wards, it is very important to pay attention to these wards to improve care. In addition, the attention of officials and planners to increase staff and increase nurses’ motivation to continue caring and improving it is important.

Since aging population is increasing, taking care of them is one of the challenges in health care system. In addition, this issue requires skilled and experienced nurses feeling passionate and motivated. Thus, this study aimed to determine the relationship between students’ perception of clinical learning environment and their willingness to caring elderly patients.

All nursing students were participated in this cross- sectional study wich was conducted using census method. Moreover, this research was performed in hospitals affiliated to Kerman University of Medical sciences that elderly patients were hospitalized there. A questionnaire belonged to Saarikoski and Aday & Campbell was used in order to collect data. The data were analyzed through Pearson, Spearman, Mann-Whitney tests using SPSS version 16.

The results showed that there is a significant relationship between the nursing students’ perception of clinical learning environment (P=0.00). This means that students’ tendency for taking care of elderly patients is increasing by enhancing their understanding of clinical learning environment.

Due to the increasing requirements of the elderly community to receive nursing care, it is necessary for nursing educational planners to consider the positive impact of clinical environment on students’ willingness in order to improve nursing the elderly patients. Furthermore, they should take the necessary interventions in this regard.

Teaching professional ethics is very important in university courses. Considering that the mentioned course has not been seen in the curriculum of undergraduate students in laboratory sciences, we decided to hold a professional ethics course for the above students. Then we decided to evaluate the mentioned course.

This quasi-experimental study was performed on 32 laboratory science students by census sampling method. The evaluation of the project was performed using the Creek Patrick evaluation model questionnaire (in the areas of reaction, learning, behavior and academic outcomes) that students answered 45 questions. The obtained data were analyzed using independent t-test and One-way ANOVA in SPSS software.

The average overall evaluation score of laboratory science students in the professional ethics is 190.09 with a standard deviation of 15.98, which is excellent based on the evaluation indicators. There is no significant difference in the average evaluation score in term of diploma major, gender and age.
Discussion and

The results of the study showed that teaching professional ethics is essential for laboratory science students. Therefore, it is recommended to include this training course in the laboratory science curriculum.
