Abstract
Background: Vitamin D plays an important role in the health, survival and fertility of humans, This Vitamin has a significant role in calcium homeostasis and cellular growth and facilitating normal immune system function. In recent years, the role of vitamin D in various diseases has been highlighted. Regarding high prevalence of vitamin D deficiency in Iran, The aim of this study was to determine the prevalence and status of vitamin D of Hamadan.
Method: A cross-sectional descriptive study in a one-year period, 7816 patients were referred to the laboratories of Shahid Beheshti and Farshchian Sina Hospitals of Hamadan Were investigated. The data was analyzed using R-version 3.2.3 and at a significant level of 0.05. The modified effect of age and sex factors on vitamin D level was investigated using logistic regression model.
Results: The prevalence of vitamin D deficiency was 0.69 in Hamadan province. 20.2% had severe deficiency (less than 10 Ng/ml) vitamin D, 20.5% moderate deficiency (10 to 20 Ng /ml), 28.6% mild deficiency (20 to30 Ng/ml), the prevalence of this deficiency was 46.7% in men and 38.7% in women. According to the results, there is a significant relationship between sex and age with vitamin D levels (p-value <0.001).
Conclusion: Based on this study and other studies, vitamin D deficiency is common in Iran and requires further investigation to improve the quality of life and prevent complications from deficiency of this essential vitamin.

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: Recurrent diabetic ketoacidosis is one of the serious and life-threatening complications of diabetes that can lead to repeated hospitalizations and significant complications. This study was conducted with the aim of investigating the prevalence, risk factors, and clinical outcomes of recurrent diabetic ketoacidosis in southeast Iran.
Methods: In this retrospective descriptive-cross-sectional study, the medical records of 560 patients with diabetic ketoacidosis during the years 2017-2020 at Afzalipour Hospital in Kerman were reviewed. Patients with at least two admissions due to diabetic ketoacidosis were included in the study. Demographic, clinical, and laboratory data were collected and analyzed using a checklist. The collected data were analyzed using SPSS software version 25 with chi-square and independent t-tests at a significance level of 0.05.
Results: Of 560 patients, 40 patients (7.16%) had recurrent diabetic ketoacidosis. The mean age of patients was 28.36 ± 15.04 years, and 60% were women. 70% of patients had type 1 diabetes. The most common underlying causes included irregular consumption or discontinuation of insulin (72.5%) and presence of infection (55%). Substance abuse was reported in 25% of patients. The mean serum levels of urea, creatinine, and potassium were 55.23 ± 37.73 mg/dL, 0.98 ± 0.67 mg/dL, and 4.38 ± 0.64 mEq/L, respectively.
Conclusion: This study showed that patients with type 1 diabetes are at higher risk of recurrent diabetic ketoacidosis. Non-adherence to insulin therapy and infections were the most important identified risk factors. These findings emphasize the importance of patient education regarding regular insulin consumption and prevention of infections.
