Background: Numerous studies have confirmed the association between type 1 diabetes mellitus (DM1) and polymorphisms of HLA genes on chromosome 6p21. Controlled DNA studies in Belgium recently have found a statistically significant association between DM1 and certain HLA class II genes, especially DRB1Lys71+.
Methods: 81 Danish families (each with at least 2 members with DM1) and 82 healthy controls were assessed for HLA polymorphisms. 54 of the 81 diabetic families were also assessed for polymorphisms at the HLA-B-DQB1, HLA-B-DQA1, and TNF-A and TNF-B loci. Affected sib-pair analysis was used to study correlation between DM1 and DRB1 alleles encoding Lys71+.
Results: Homozygous expression of DRB1Lys71+ carried a relative risk (RR) of 103.5 for DM1. There was a very strong correlation (p<1×10-6) between DM1 and DRB1 alleles encoding Lys71+. Family-based association studies showed that DRB1Lys71+ was the most important determinant of DM1 in carriers (haplotype relative risk = 8.38). Haplotype analysis confirmed this.
Conclusion: The DRB1Lys71+ allele confers genetic predisposition to DM1 most strongly of all.

Background: Family satisfaction in subpopulations referred to the endocrine clinic including diabetic and non diabetic patients and their spouses are compared in the present study. This study also assesses the correlation between family satisfaction and variables such as age, sex, educational level, economic status, type of diabetes, duration of the disease, type of therapy and dosage of drugs. A comparison of the frequency of sexual dysfunction between diabetics and non-diabetic pairs was also done.
Methods: In this case- control study, 400 subjects were selected as simplified non-randomized method from outpatients referred to the Shahre Kord endocrine clinic in 2002. We assigned samples to group I (diabetic patients, n=100), group II (diabetic patients spouses, n=100), group III (non-diabetic patients, n=100) and group IV (non-diabetic patients spouses, n=100). Groups I and II were similar in sex, socioeconomic status and educational level. GRIMS family relationship questionnaire was used to evaluate family satisfaction.
Results: Family satisfaction for diabetics in comparison with non-diabetics (P=0.05), diabetics in comparison with their spouses (P=0.003), and non-diabetics in comparison with their spouses (p=0.002) were significantly less. There was no significant difference between family satisfaction in diabetic and non-diabetic patients spouses (p>0.05). Relative frequency of sexual dysfunction was 76% and 29% and relative frequency of decreased libido was 32% an 12%, in diabetic and non- diabetic couples, respectively. Family satisfaction was less in patients with diabetes type I and whom using higher dosage of drugs.
Conclusion: This study emphasized on the attention to the family as a part of approach to the diabetic patients. According to our results, it is recommended to focus the most attention in this field to the patients with type I diabetes and who consume more amounts of drugs.

Background: Cardiovascular Diseases are becoming increasingly prevalent due to urbanization and industrialization of our country. Therefore Screening of the Cardiovascular Risk Factors is one of the most important health system priorities. The aim of this study was to evaluate a screening method implementing family history for cardiovascular risk factors.
Methods: We chose 10 Junior-high schools in the 6th district of Tehran using simple random sampling. Then a questionnaire asking about family history of cardiovascular disease in the first degree relatives (including grand parents) was distributed between them and was completed – with contribution of parents. Then high-risk and low-risk families were invited separately to Dr Shariati Hospital for further evaluation. SPSS software version 10 using student T-test, Chi-Square and descriptive tests were applied for data analysis
Results: Approximately 40% of families had positive family history (high risk). From this group, 72% participated for follow-up. From the low-risk group, only 34% participated. Total cholesterol and LDL-C levels were significantly higher in high risk (HR) group. FBS was also significantly higher in fathers and children of the HR group (P<0.05). High TC, LDL-C and FBS levels were more prevalent among the HR families (P<0.05). No significant differences were observed in age, BMI, BP, TG and HDL-C between the 2 groups.
Conclusion: Families with a history of cardiovascular disease participated in greater numbers in the screening process and the prevalence of risk factors in this group was significantly higher. The findings confirm the usability of family history in screening programs.

Background: Obesity is one of the most important risk factors for cardiovascular disease and genetic and environmental factors play important role in this risk factor. The aim of present study was to estimate the heritability of anthropometric variables in Tehran Lipid and Glucose Study (TLGS) families. Methods: In this cross-sectional study, 529 two generation families were selected from among phase III TLGS. At least two members of the families were overweight or obese. Anthropometric variables, resting energy expenditure (REE) and body size index (BS) were determined. The heritability (h2) of variables was estimated using SOLAR software. Results: In this study, 2460 individuals (493 fathers, 573 mothers, 720 sans, 674 daughters) participated, and the mean age of parents and offspring were 45.7±10.2 and 18.4±9.7 years respectively. In Tehran families, the sex and age adjusted heritability for anthropometric variables varied from 0.21(0.037) (hip) to 0.51(0.035) (BS) as expected, body size as a skeletal trait had the highest heritability. By considering the BS as a confounder, the REE heritability increased from 0.26 to 0.47. Therefore body size may have important role in determining the heritability of this variable. Conclusion: genetic factors have decisive role in obesity phenotype of Tehran families.

Background: According to the importance of the family physicians program results in rural areas and government decision to apply this program in urban areas of Iran, This study aimed to determine the quality of care and blood sugar control, blood pressure and blood lipids in diabetic type &Iota&Iota patients in rural areas covered by family physicians. Methods: In this study, 380 patients 30-76 years old with medical records in the health centers of the malekan-Iran in rural areas in 2013, after informed consents were enrolled. Data were collected by interview and HbA1c examinations and using a standard questionnaire. Data analyzed by SPSS19 version. Multivariate logistic regression was used to estimate odds ratios adjusting for diabetes complications and related risk factors. Results: Results showed that 68% Study participants was women’s and average age of patients was 57.86±11.9 and sex ratio of females to males was almost 2.2 with 1. Final analysis showed that HbA1c levels more than 7% (PHbA1c=0.002), cholesterol over 240 mm/dl (Pcholesterol=0.04) and hypertensive over 140/90mm/Hg (PHTN=0.007) 1.52, 2.44 and 1.44 times increased risk of diabetes complications, respectively. Conclusions: The quality of care and blood sugar control in diabetic patients was lower than compared to the American Diabetes Association (ADA) standards, but our results are near to results of Country studies.

Background: Unc-51 Like Autophagy Activating Kinase-1 (ULK1) and FAK Family Kinase-Interacting Protein of 200 kDa (FIP200) play an essential role in controlling autophagy and muscle volume. The aim of this research is to investigate the effect of endurance training on the intracellular content of ULK1 and FIP200 proteins in the left ventricular of rats with type 1 diabetes.
Methods: In this experimental study, 18 rats 2-month-old male Sprague-Dawley rats with a mean weight of 300±20g were selected. 12 rats became diabetic by intraperitoneal injection of Streptozotocin solutions. These rats were randomly divided into 2 groups: diabetic training and diabetic control (6 heads per group); A healthy control group (6 heads)was also considered. The training group practiced endurance training 4 days a week for 6 weeks. Data were analyzed using SPSS software version 23 and one-way ANOVA and Tukey post hoc tests.
Results: The content of ULK1 (increase) and FIP200 (decrease) after endurance training showed a significant change among the research groups in the left ventricular (P=0.0001). Tukey's post hoc test showed that this change is significant between the pair of diabetic training groups to diabetic control, diabetic training to healthy groups, and also diabetic control to healthy groups (P≤0.05).
Conclusion: Endurance training showed that it can have a dual nature to control autophagy in diabetic subjects by increasing ULK1 and decreasing FIP200. There is a need for more investigations in the field of exercise physiology on the proteins responsible for autophagy, especially in type 1 diabetes subjects.

Background: Diabetes can cause serious cardiovascular complications by disrupting the autophagy pathway. Therefore, this study aimed to investigate the effect of high-intensity interval training (HIIT) on the intracellular levels of autophagy proteins in the left ventricular tissue of rats with type 1 diabetes.
Methods: In this experimental study, 18 2-month-old male Sprague-Dawley rats with an average weight of 300±20 grams were selected. Twelve rats had type 1 diabetes after intraperitoneal injection of STZ (with a dose of 50 mg/kg of body weight) solution. Rats were randomly divided into two groups: diabetic training and diabetic control (each group, six heads). A healthy control group (six heads) was also considered. The training group underwent HIIT four days a week for six weeks. GraphPad Prism version 9.5 software and one-way ANOVA, and Tukey's post hoc tests were used to analyze the data. The significance level was considered P≤ 0.05.
Results: ULK1 and FIP200 levels showed a significant increase in the left ventricle after 6 weeks of HIIT training compared to the healthy control group and the diabetic control group (P= 0.0001).
Conclusion: Considering the increase in ULK1 and FIP200 proteins, it can be concluded that HIIT training can activate the autophagy pathway; Therefore, in prescribing this type of exercise for diabetic subjects, the intensity and duration of the exercise should be considered.

Background: Type 1 diabetes is the most common type of diabetes affecting children and adolescents. Nursing interventions for children with type 1 diabetes include recognizing the adolescent's problems and providing technical care and emotional support. Nurses play an important role in helping adolescents and their families manage emotions, adjust treatment regimens, and integrate new routines into daily life. The aim of this systematic review is to identify and analyze effective nursing interventions in the management of type 1 diabetes in children and support their families. This study, by reviewing the available evidence, attempts to explain the role of nurses in improving clinical, psychological, and behavioral outcomes in children and promoting awareness, self-care skills, and quality of life in families.
Methods: A systematic search was conducted in the scientific databases PubMed, Scopus, Web of Science, CINAHL, SID and Magiran between 2010 and 2025. The search strategy was created using the PubMed keywords (Nursing Interventions) [title/abstract], (Type 1 Diabetes), (Child) and (Family). Systematic search with English keywords: ((Nursing Interventions[title/abstract]) AND (Type 1 Diabetes [title/abstract])) AND (Child[title/abstract])) AND (Family[title/abstract]). Out of 500 studies on nursing interventions in pediatric type 1 diabetes with more detailed review, a total of 10 studies met the inclusion criteria and were included in the final analysis.
Results: The findings showed that nursing interventions can have a significant impact on diabetes management by children and families, leading to improved adherence to treatment regimens, better blood sugar control, and increased quality of life for children and families.
Conclusion: Nursing interventions play a significant role in improving blood sugar control, increasing awareness and self-care of children with type 1 diabetes, and supporting their families. Interventions such as patient and family education, psychological counseling, regular follow-up, use of educational and care-oriented technologies, and team collaboration have been able to provide favorable results in reducing disease complications, improving quality of life, and increasing psychosocial adjustment. Accordingly, the development and implementation of evidence-based intervention programs, taking into account the individual, cultural, and social characteristics of families, is recommended to improve nursing care in children with diabetes.
