Abstract
Background: Health staffs have different attitudes and beliefs toward elders that have effect on their behaviors in health service delivery to elders. This study was done for determination of Golestan province health centers general practitioners (GPs) attitude toward elders.
Methods: In this cross sectional study, 152 general practitioners of Golestan province health centers were selected via random sampling. The Kogan's Attitudes toward Older People Scale (KAOPS) questionnaire was used as data gathering tools. Data analysis was done in SPSS 16 software using Pearson correlation coefficient, paired t-test, t-tests and one way ANOVA test.
Results: Mean (standard deviation) of participants age was 34.73 (6.26) years. Mean (standard deviation) of total score of attitude toward elder scale was 115.48 (10.22) (score range in scale 34-204). 54.2 percent of GPs have lower score than mean. Negative attitude mean score were higher than positive attitude mean score which was statistically significant (P= 0.0001).
Conclusion: According to our finding, only half of GPs had favorite attitude toward elder. Whereas negative attitudes were higher than positive attitude toward elder, designing some programs for change in attitude of heath care staffs is necessary.

Abstract
Background: One of the common problems of the elderly, which increase of its prevalence with aging is the dementia and the cognitive impairment. We can help the involved patients to have a better quality of life with early diagnosis of the cognitive impairment. The aim of this study was an assessment of the validity and reliability of the Persian version of the abbreviated mental test (AMT) among the older people in a nursing home setting.
Methods: 176 eligible elderly people aged ≥ 60 years living in KahrizakCharity Foundation (KCF), were selected randomly based on medical record number. Demographic information and past medical history of the participants were collected. Geriatric depression scale 15 (GDS-15), global deterioration scale (GDS) forms and also the Persian version of the abbreviated mental test (AMT) were administered. The participants were assigned to two groups the normal and impaired cognitive groups, based on DSM-IV diagnostic criteria. The GDS cut-points were used for assessment of validity, sensitivity and specificity of the Persian version of AMT.
Results: The mean age of the participants was 77.30 (7.94) years. The Persian version of AMT had good discriminated validity in diagnosis of normal and impaired cognitive participants (7.35 ± 2.33 and 5.99 ± 2.29, P < 0.01 respectively) and at cut-point AMT< 8,(based on GDS cut-point) it had a sensitivity and specificity 92.15 % and 81.50% respectively. The sensitivity and specificity based on theism IVcriteriawere 64.9% and 64.0% at cut-off point equal to 7, respectively. The internal consistency of the Persian version of AMT was acceptable (Cronbach’salpha coefficient =0. 76). As well as the external reliability (intra-rater) of this instrument was good inter-class correlation coefficient (ICC) = 0.89)
Conclusion: The Persian version of the AMT has appropriate validity and reliability in Iranian older people.

Abstract
Background: Diabetes is a chronic disease that can cause severe complications such as cardiovascular disease, blindness and kidney failure. Given the importance of self-care in diabetic patients, and considering that inadequate health literacy is a serious barrier for the management of diabetes that can affect patients' participation in self-care, Therefore this study aimed to assess the status of health literacy in patients with type 2 diabetes in three domains of functional, communicative and critical and Determine the factors associated with self-care behaviors in these patients. Methods: A cross-sectional study on 187 diabetic patients referred to Hazrat Ali diabetes clinic in Isfahan. The samples were selected by randomly Convenience sampling method. The level of health literacy and Status of self-care behaviors in patients was assessed by a standardized questionnaire (FCCHL) and (DMSES) respectively. Collected data were analyzed Using the ANOVA, t-independent, Pearson correlation coefficient at SPSS v.21 statistical software. Results: The mean age of the study population was 57.40 ± 11.07. Average health literacy score and self-care behaviors of the participants were 2.28± 0.57 and 3.84 ± 1.56 respectively. There was significant relationship between total health literacy, communicational and critical health literacy with self-care behaviors. There was no significant relationship between functional health literacy and self-care behaviors. Communicational health literacy was associated with diet, physical activity, blood glucose monitoring and foot care. Critical health literacy was associated with physical activity, blood glucose monitoring, foot care, and taking medication. There was no significant relationship between Communicational health literacy and taking medication and also between critical health literacy and diet. Conclusion: Considering that communication and critical health literacy was associated with the self-care of patients with diabetes so Emphasis and consideration should primarily be given on skills related to these domains of health literacy. Since that Patients’ functional HL capabilities that was associated with basic skills in reading and writing was not related to self-care, therefore assessment of education levels alone in the clinical setting is not recommended.

Abstract
Background: Diabetes is a chronic and prevalent disease. In recent years, its prevalence has increased because of lifestyle changes, immobility and subsequent obesity. The increase in diabetes prevalence has provoked multiple and scattered interventions by specialists and health care providers in order to control and regulate blood sugar and its related factors. The purpose of this study was to collect and integrate the results of these interventions in two fields of psychological and sport interventions and to investigate the impact of them on control of Glycosylated haemoglonin (HbA1c) in patients with diabetes by meta-analysis method.
Methods: For this purpose 38 acceptable studies (19 sport interventions and 19 psychological interventions), in terms of methodology, were selected and meta-analysis performed on them. This study is based on 38 effect sizes and research instrument is checklist of meta-analysis.
Results: The study findings showed that the effect size of psychological interventions on control of Glycosylated haemoglonbin is 0.67 (p<0.00001) and the effect size of sport interventions is 0.79 (p<0.00001).
Conclusion: according to Cohen’s chart, the effect size of both psychological and sport intervention on control of Glycosylated haemoglonin in patients with diabetes is medium. However, the effectiveness of sport interventions have been obtained more than the psychological intervention

Abstract
Background: Prevalence of diabetes increases along with aging. Due to various reasons, rate of falling in the aged suffering from diabetes is higher. Therefore, this study aims at determining factors relating falling of the aged suffering from type 2 diabetes.
Methods: A total of 60 years old or older with type 2 diabetes that referred to selected hospitals of Tehran University of Medical Sciences using continues method. Cases that had experienced falling during last year and controls that had no such experience were assigned to two separate groups. Questionnaire used in this study included demographic data and factors relating falling. Data obtained were analyzed using descriptive statistics, independent t- test, Chi square and logistic regression.
Results: Results showed that postural blood pressure (p=0.02) dizziness (p=0.05), fecal incontinency (p<0.01), auditory disorder (p<0.01), visual disorder (p<0.01), pain in the lower extremity (p= 0.027), taking anti-coagulation medicine (p=0.017) had a significant correlation with falling.
Conclusion: Multivariate logistic regression illustrated that fecal incontinency and auditory disorder happened along with falling in the aged suffering from type 2 diabetes. Therefore, preventing falling must be considered in care plan for such groups of people.

Abstract
Background: Although several tools for evaluating and screening of cognitive status have been introduced, most of them are not applicable in Iranian elderly population because of cultural differences and high illiteracy rate. This study is report of "Brief Cognitive Assessment Tool"(BCAT) was developed as a cognitive status-evaluating test and reported psychometric characteristics.
Methods: the BCAT tool includes memory assessment using three words recall test with a rating similar to Mini-Cog and the functional status including "ability to dress", "ability to use the phone," " ability to manage own medications", among both two sexes and financial management capabilities in men and ability to prepare food in women. Functional rating is different in educated and non-educated people. Diagnosis of dementia is considered, when memory impairment is accompanied by the dysfunction. Eighty-six residents of a nursing home (41 men and 45 women) among who had inclusion and no had exclusion criteria also consent to participate were randomly enrolled. Concurrent validity was shown as correlation coefficient between the BCAT categorization and score of mini meAntal state examination (MMSE). Criterion validity, sensitivity and specificity of BCAT were evaluated based on global deterioration scale (GDS). Reliability of two raters results within two weeks was indicated by Kappa coefficient.
Results: The sensitivity and specificity and accuracy rate of the BCAT based the GDS was 88.6%, 82.6%, and 84.9%, respectively. The correlation between the MMSE score and results of the BCAT classifying was significant. The Kappa coefficient between the results of two raters was 81.1%.
Conclusion: It seems that the BCAT has good psychometric properties to recognize cognitive impairment among Iranian older adults.

Abstract
Background: Diabetes is one of the most common diseases of the body's endocrine system, Based on present forecasts of its prevalence will increase in human societies. Diabetes mellitus consists of 5 groups, its two major groups: type I diabetes or insulin-dependent and type II diabetes or non-insulin dependent diabetes. The aim of this study was to evaluate the effect of alcoholic extract of green wheat leaves on glucose, cholesterol, triglycerides, LDL, HDL and total antioxidant capacity of blood serum in alloxan-induced diabetic mice.
Methods: In this study, 40 male mice with an average weight of 25-20 grams in eight groups of five rats: The negative control, positive control (sham), Methformin (60mg/kg), green Wheat leaf extract (100, 200, 400, 800 and 1000mg/kg) were tested. Blood glucose was measured at baseline, then in the positive control group and the experimental groups by Alloxan (120mg/kg) Diabetes was induced by intraperitoneally. During the study, the positive control group and experimental groups received aforementioned compounds for 10 days via intraperitoneally and after 48 hours of each group blood samples were taken through the intraventricular anesthesia and glucose, cholesterol, triglycerides, LDL, HDL and total antioxidant capacity in serum were measured. Quantitative results achieved in this research by one-way ANOVA and Tukey post hoc test between the groups studied Considering the significance level of p <% 5 were analyzed.
Results: The results showed that blood glucose changes in green Wheat leaf extract and metformin groups compared with the positive control group and negative control group was significant at the 5% level and In all under study groups blood glucose levels, Compared with the positive control group decreased and is close to the negative control group also in doses of 100, 200, 800 and 1000 mg/kg Reduced blood glucose is better than methformin group. Methformin and green Wheat leaf extract caused a significant increase at all doses studied in the TAC's Blood. Methformin and green Wheat leaf extract on the amounts of LDL, HDL and cholesterol in diabetic groups had no significant effect and did not have significant difference with other groups. There was no significant effect of different doses of green Wheat leaf extract on the blood triglycerides. However, metformin has a significant impact on triglyceride levels.
Conclusion: The results of the effects of green Wheat leaf extract on glucose and serum antioxidant capacity
It can be noted that these extracts in the treatment of diabetes and reduce its complications can be considered as an option.

Abstract
Background: The aim of this study was to estimate the prevalence of clinical hyperthyroidism at the national and sub-national levels using the claims data.
Methods: National anti-thyroid medications (methimazole and propylthiouracil) sales data in 2014 were extracted from pharmaceutical sales data that were reported by Iran's Food and Drug Administration (FDA). By using prescriptions data of Social Security Insurance Organization (SSIO) and Medical Services Insurance Organization (MSIO) in 2014, age-sex-province proportions of drug consumptions and Defined Daily Dose (DDD) of anti-thyroid medications were calculated. Moreover, by systematic review and meta-analysis of published literatures in hyperthyroidism in Iran, the prescription rate of anti-thyroid medications was calculated. Finally by using the whole data, the prevalence of clinical hyperthyroidism was estimated in each age and sex groups in national and provincial levels.
Results: : The prevalence (95% confidence interval) of clinical hyperthyroidism in Iran in 2014 is 0.32% (0.21-0.51%); 0.44% (0.29-0.68%) in females and 0.2% (0.12-0.33%) in males. Among provinces the least prevalence rate of clinical hyperthyroidism is 0.24% (0.16-0.38%) which belongs to Sistan and Baluchistan, and the highest prevalence rate is 0.38% (0.24-0.6%) which belongs to Gilan.
Conclusion: The prevalence rate that reported by this study is compatible with other surveys which performed in the world and Iran. As a result using claims data is a good source to predict prevalence of chronic diseases that have specific drugs.

Abstract
Background: In this study, we investigated the diagnostic power of ultrasound in the diagnosis of malignancy in thyroid nodules in Iranian patients. For this purpose, we examined the relationship between ultrasound findings and pathology findings.
Methods: The present study is a retrospective study. The patients with a diagnosis of thyroid nodules who underwent ultrasound and FNA, were included in this study. To assess the relationship between the results of FNA and the ultrasound characteristics of nodules, we classified the results of FNA into malignant and benign groups and then compared ultrasound characteristics between the two groups. In cases which the FNA results were indeterminate (AUS/FLUS or FN/SFN), the postoperative pathology result was considered (if thyroid surgery was done and the result was available).
Results: In total, 201 nodules were included in this study. The results showed that hypoechogenicity, irregular/ill-defined margin, microcalcification, malignant flow pattern in Doppler sonography and concurrent cervical lymphadenopathy with suspicious features were significantly associated with malignant thyroid nodules. However, other ultrasound findings, such as the size and location of the nodule, presence of a cystic components within the nodule, the presence of a Halo sign, and the presence of a taller-than-wide shape, could not distinguish between benign and malignant nodules. Finally, the results of the present study showed that the accuracy of ultrasound in the diagnosis of malignancy in thyroid nodules is high.
Conclusion: This study suggests that the use of ultrasound can be very effective in diagnosing malignancy in thyroid nodules.

Abstract
Background: Muscle atrophy is one of the serious complications of type 1 diabetes. Important cellular mechanisms including pathways related to mTOR protein are very important in regulating muscle mass; Therefore, this research was conducted to investigate the effect of high-intensity interval training (HIIT) on the intracellular content of the central protein of mechanical target of rapamycin 1/2 complexes in EDL skeletal muscle of rats with type 1 diabetes.
Methods: In this experimental study, 12 three-month-old male Sprague-Dawley rats with an average weight of 300±20 grams were selected. Type 1 diabetes was induced through intraperitoneal injection of streptozotocin solution (50 mg/kg of body weight). These rats were randomly divided into two groups, diabetic exercise, and diabetic control; The training group performed HIIT for six weeks at an intensity of 85-95% of maximum speed. Data analysis was done through an independent t-test in SPSS software version 28. A significance level of 0.05 was considered.
Results: The intracellular content of total and phosphorylated forms of mTOR protein showed a significant increase after six weeks of HIIT (P=0.0001). Also, the ratio of total to phosphorylated intracellular content of mTOR protein showed a significant increase in the training group compared to the control group (P=0.0001).
Conclusion: HIIT increased the intracellular content of total and phosphorylated forms of mTOR protein, which could possibly lead to protein synthesis and increased muscle hypertrophy.

Abstract
Background: Cardiac function in diabetic people is affected through different cellular mechanisms; One of these important cellular pathways is the c-Jun N-terminal kinases (JNKs), whose dysfunction can lead to heart failure; Therefore, the aim of this research is to investigate the effect of moderate intensity interval training on total and phosphorylated content of c-Jun N-terminal kinases protein in heart tissue of type 1 diabetic rats.
Methods: In this experimental study, 12 two-month-old male Sprague Dawley rats with an average weight of 300±20 grams were selected. Type 1 diabetes (blood sugar above 300) was induced to rats through intraperitoneal injection of streptozotocin (with a dose of 50 mg per kilogram of body weight) solution. The rats were randomly divided into two groups, diabetic training and diabetic control; The training group performed MIIT for four weeks at an intensity of 55-75% of maximum speed. Data analysis was done through independent t-test in GraphPad Prism software version 9.5. The significance level of the current research is P≤ 0.05.
Results: The intracellular content of JNK protein after four weeks of MIIT showed a significant decrease in both total (P= 0.01) and phosphorylated (P= 0.0001) forms. On the other hand, the ratio of total to phosphorylated intracellular content of JNK protein did not show a significant change after four weeks of MIIT (P= 0.23).
Conclusion: MIIT led to a decrease in the content of total and phosphorylated forms of JNK protein, which could possibly lead to less cell death in cardiac cells of diabetic subjects.

Abstract
Background: Mitophagy is a type of cell death that regulates the quality of mitochondria and can lead to disorders in diseases such as diabetes. Therefore, the purpose of this study was to investigate the effect of high-intensity interval training (HIIT) on the content of proteins related to the mitophagy pathway (LC3 and BNIP3L) in muscle tissue soleus of rats with type 2 diabetes.
Methods: In this experimental study, 18 three-month-old male Sprague Dawley rats with an average weight of 270±30 g were selected. Rats were infected with type 2 diabetes by intraperitoneal injection of a streptozotocin and nicotinamide solution. Rats were randomly divided into two groups: diabetic and diabetic. A healthy control group was also included. The training group performed HIIT for eight weeks at an intensity of 85-95% of the maximum speed. Data analysis was performed using a one-way ANOVA test in GraphPad Prism version 9.5 software. A significance level of P≤ 0.05 was considered statistically significant.
Results: The levels of LC3 and BNIP3L proteins significantly increase after eight weeks of HIIT compared to both the diabetic and healthy control groups (P= 0.0001).
Conclusion: It can be concluded that HIIT by increasing the factors related to mitophagy can cause the cleaning of dysfunctional mitochondria in the muscle of diabetic subjects; However, excessive mitophagy can also cause functional defects in regulating the quality of mitochondria.
