Background: The relationship between diabetes and periodontal diseases has already been proved, but the effect of non-surgical periodontal therapy on the control of diabetes is controversial. The aim of this study was to determine the effect of this type of treatment on the control of diabetes.
Methods: In this randomized clinical trial 30 type 2 diabetic patients with moderate to severe periodontitis who were referred to the diabetes clinic of Imam Khomeini hospital during 2004-2005 were studied. The treatment procedure was explained for control group and an informed consent was taken. Scaling and root planning was randomly done for 15 patients, while control group were not treated for periodontal disease. The glycated hemoglobin (HbA1C) and clinical attachment loss was measured for all of the patients before and 2 months after treatment.
Results: At the baseline the clinical attachment loss (CAL) was significantly different between two groups. There was no significant difference between baseline HbA1C in the control and the experimental group. After 2 months the HbA1C was reduced in the treated group which was not statistically significant.
Conclusion: In this study non-surgical periodontal therapy had not effect on the control of type 2 diabetes.

Background: Alternate Day Fasting (ADF) is one of dietary regimens in which food is available only every other day. Available limited evidence shows that this regimen may result in beneficial effects similar to classic caloric restriction, including weight loss and other associated useful effects of weight loss. Methods: Twelve week-old Wistar rats were obtained from animal house of Jundi Shapur University and fed a standard diet. Food was provided ad-libittum (AL) until 13 week of age. At that time rats were assigned to one of two groups: AL fed ad libitum or ADF, provided access to food every other day. Body weight was measured each week on the same day and time. Food intake was measured daily. Fasting blood glucose levels were measured before and after the intervention. Statistical tests performed as two-tailed and P value of less than 0.05 was considered as statistically significance level. Results: At the end of the intervention period body weight and food intakes of the (ADF) group were significantly lower than AL group (p<0.05) but there were not significant changes in fasting blood glucose levels. Conclusion: According to findings of this experimental study, ADF regimen could be used as an individualized eating strategy for weight loss but it could not have beneficial effects on fasting blood glucose levels.

Background: increasing the population of aged, Consequently Increasing rate of chronic disease and to decreasing quality of life level caused many problems in different communities. The important aim of this study was surveying the effect of an educational intervention by use of the educational components of precede model on quality of life in the elders. Methods: This semi-empirical research was performed on 54 aged people in two group-case and control- for the Aged in 2009. In this study two questionnaires the designed questionnaire based on PRECEDE model and the questionnaire on the quality of life standard of the World Health Organization (WHOQOL) were used and the quality of life of the aged people in two groups before and after one month from the educational interference was evaluated. Independent t-test paired T-test, one way ANOVA, was used for data analysis. Results: The average total score of the quality of life of the aged people of test group, showed a meaningful difference before and after educational interference with a p quality less than 0.05, but there wasn’t a meaningful difference between total scores of two groups. Though the relationship of attitude (predisposing factors), enabling factors (skills) and behavioral factors with quality of life of a p quality less than 0.05 was meaningful. But knowledge (predisposing factor) and reinforcing factors didn’t show a meaningful relationship with the quality of life. Conclusion: It seems that the health, education and health promotion programs are effective on quality of life in the aged people.

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.

Background: Insulin resistance and progressive β-cells failure are the key factors in type 2 diabetes mellitus (T2DM) pathogenesis. Many studies support a primary role of RBP4 in insulin resistance and suggest that genetic variations which alter the expression level of RBP4 might influence the risk of T2DM and its complications. Diabetic foot is one of the main complications of diabetes leading to disability and hospitalization. In addition, it reduces quality of life and imposes great cost to patients. The purpose of this study was to evaluate the correlation between two single nucleotide polymorphisms (rs10882273 and rs10882283) of RBP4 genes with diabetic foot ulcer in order to identify a biomarker for prediction of diabetic foot ulcer.

Methods: This is a case-control study. Two single nucleotide polymorphisms of RBP4 genes were genotyped by hit Tetra ARMS PCR technique. In this study, 100 and 133 diabetic patients with and without foot ulcer were selected as the cases and controls, respectively.

Results: The Chi-square test revealed no significant difference in frequency of TT, CC and TC alleles of rsl0882273 between case and control groups (P=0.414). Also, Comparison of AA, CC and AC alleles of rsl0882283 in both groups did not show significant difference (P=0.85).

Conclusion: According to this study, there is no relationship between two single nucleotide polymorphisms of RBP4 genes (rs10882273 and rs10882283) with diabetic foot ulcer in type2 diabetes patients.

Background: Type 2 diabetes is a metabolic disorder characterized by high blood sugar levels that can damage nerves. Many organs are affected ،especially the foot that leading to loss of sensation. These factors make favorable conditions for the development of diabetic foot ulcers. Polymorphisms (Thr399Ile) of Toll Like Receptor4 (TLR4) gene due to malfunction of TLR4 protein which plays an important role in immunity. The purpose of this study was to determine the parameters which are affecting the imbalance resulting in chronic inflammation and wound healing. By showing the relationship between single nucleotide polymorphism (Thr399Ile) of TLR4 gene with diabetic foot ulcer we can identify a biomarker for prediction of diabetic foot ulcer.
Methods: This is a case-control study. Single nucleotide polymorphisms of TLR4 gene were genotyped by hit Tetra ARMS PCR technique. In this study, 100 and 120 diabetic patients with and without foot ulcer were selected as the cases and controls, respectively.
Results: The Chi-square test revealed significant difference in frequency of TT, CC and TC alleles of (Thr399Ile) between case and control groups (P=0.021).
Conclusion: According to this study, there is a relationship between single nucleotide polymorphisms (Thr399Ile) of TLR4 gene with diabetic foot ulcer in type 2 diabetes patients

Background: Type 2 diabetes is the most common type of diabetes, and a complex endocrine metabolic disorder that one of its main complications is diabetic foot ulcers. Matrix metalloproteinases (MMPs) are one of the key enzymes in the reconstruction of extracellular matrix which have proteolytic activity. The aim of this research is based on evaluating relationship between -1562 C>T allele at MMP-9 gene promoter with diabetic foot ulcer in type II diabetic patients. If such correlation proves, it can be used as a prognostic biomarker in patients with high-risk.
 Methods: This is a case-control study. The single nucleotide polymorphism of -1562C>T allele of MMP9 gene promoter was genotyped by hit Tetra ARMS PCR technique in 100 diabetic patients with foot ulcer grade 1 or 2 as the case group according Wagner classification and in 100 diabetic patients without foot ulcer as the control group. Results: The Chi-square test revealed significant difference in genotype frequency of CC, CT and TT alleles of -1562C>T allele of MMP9 gene promoter between case and control groups (P=0.000).
Conclusion: According to this study, there is a relationship between -1562C>T allele of MMP9 gene promoter with diabetic foot ulcer in type2 diabetes patients. Thus we can introduce this biomarker for evaluation of risk and prognosis of diabetic foot ulcers.

Background: Type 2 diabetes is a chronic and debilitating disease that affects the life expectancy and self-care behaviors of women with this disease. Therefore, the present study aimed to investigate the effectiveness of existential therapy on life expectancy and self-care behaviors of women with type 2 diabetes.
Methods: The research method was applied and quasi-experimental with pre-test and post-test design with control group. The population included all women with type 2 diabetes in Neyshabur, Iran. Among them, 40 people were selected by available sampling method and randomly assigned to experimental and control groups. Participants completed the Hope Scale (HS), and The Summary of Diabetes Self-Care Activities (SDSCA). Multivariate analysis of covariance was used to analyze the data.
Results: The results of analysis of covariance showed that there was a difference between women in the existential therapy group and the control group in life expectancy (F= 10.11, P= 0.0001) and self-care behaviors (F= 176.5, P= 0.003). Existential therapy has increased the mean score of the participants of the experimental group in the variables of life expectancy and self-care behaviors.
Conclusion: The existential therapy can increase life expectancy and self-care behaviors of women with type 2 diabetes by emphasizing freedom, responsibility, meaning and purpose in life, death and relationship with other. Therefore, existential therapy can be used in along with medical treatments.
