Introduction: The frequencies and functions of T stem cell memory (TSCM) subsets vary in autoimmune diseases. We evaluated the frequencies of CD4+ and CD8+ TSCM subsets as well as their PD‐1 expression levels in patients with T1D. Methods: Blood samples were collected from new case (NC) (n = 15), and long‐term (LT) (n = 15) groups and healthy controls (n = 15). Five subsets of T cells including TCM(CD4+/CD8+ CCR7+ CD45RO+ CD95+), TCMhi (CD4+/CD8+ CCR7+ CD45ROhi CD95+), TEM(CD4+/CD8+ CCR7− CD45RO+ CD95+), TSCM(CD4+/CD8+ CCR7+ CD45RO− CD95+), and T naive (CD4+/CD8+ CCR7+ CD45RO− CD95−) were detected by flow‐cytometry. Results: The frequency of CD4+ TSCM was higher in NC patients than LT patients and controls (p <.0001 and p =.0086, respectively). A higher percentage of the CD8+ T naive cells was shown in NC patients as compared with LT and healthy individuals (p =.0003 and p =.0002, respectively). An increased level of PD‐1 expression was observed on the CD4+TCM and TCMhi cells in LT patients as compared with healthy controls (p =.0037 and p =.0145, respectively). Also, the higher PD‐1 expression was observed on the CD8+ TCM and TCMhi in NC and LT patients as compared with controls (p =.0068 and p <.0001; p =.0012 and p =.0012, respectively). Conclusion: Considering TSCMs' capacities to generate all memory and effector T cells, our results may suggest a potential association between the increased frequencies of TSCMs and T1D progression.

Nowadays, the introduction of the so-called ‘diabetes technology’, either hardware/device or software, to different aspects of day-to-day living in patients with diabetes aims to improve blood glucose control and various lifestyle features. The coordination of vast context of diabetes education/training, particularly in the area of medical nutrition therapy, is considered as a great concern. On the other hand, Iranian food culture consists of a set of traditional dietary patterns and food consumption habit. The study was aimed to develop “the Comprehensive Mobile Application of Advanced Carbohydrate Counting and Diet- and Insulin-Regimen Planning” to help type 1 diabetic patients, improving their health status. The programming language of Kotlin, JavaScript, Node JS, and HTML5 was used for the mobile app development. The app was developed with the following abilities: 1) educating users on different aspects of disease control including, updated general treatment guidelines on physical activity, medical nutrition and insulin therapy, stress management, and the patient’s specific goals and dietary needs, 2) performing advanced carbohydrate counting using both picture-represented and kitchen-scale of carbohydrate foods as well as traditional Iranian foods, 3) recommending the patient’s specific insulin dose, either short- or rapid-acting, based on the carbohydrate content of the selected meal or the selected amount of Iranian foods, 4) recommending the personalized insulin dose needed for decreasing the high blood glucose levels, and 5) performing 3 and 4 simultaneously. Developing Carbulin was an effort to increase type 1 diabetes self-management using the traditional Iranian dietary pattern and menu. [ABSTRACT FROM AUTHOR]

Background: Type I Diabetes Mellitus (T1DM) is one of the most common endocrine diseases in the world. It is also the dominant type of diabetes mellitus among children and adolescents that, if left uncontrolled, becomes a major risk factor for cardiovascular disorders and may cause clinical and subclinical cardiac dysfunction. Objective: This study aimed to compare uncontrolled pediatric and adolescent patients and similar healthy people regarding cardiac function according to echocardiography and B-type Natriuretic Peptide (BNP). Methods: This case-control study was carried out in the Outpatient Department of Nemazi tertiary hospital in Shiraz, Iran between June and September 2016. The study included 29 consecutive outpatient cases aged 5 - 18 years who had been diagnosed with T1DM for more than three years and had normal ejection fraction in M-mode echocardiography. The control group consisted of 29 age- and gender-matched healthy non-diabetic volunteers. Both cases and controls were selected by simple random sampling. The participants underwent clinical evaluation, including BNP assay and echocardiographic examination composed of two-dimensional echocardiography, M-mode echocardiography, pulsed Doppler imaging, and Tissue Doppler Imaging (TDI). P-value ≤ 0.05 was considered to be statistically significant. Results: The results revealed a decline in cardiac function in TDI, which was related to the HbA1C level and duration of the disease. A significant difference was found between the cases and the controls regarding the left ventricular posterior wall, interventricular septal diameters in diastole, and E/A ratio of tricuspid valve (P = 0.047, P = 0.001, and P = 0.021, respectively). A significant difference was also observed between the two groups in terms of septal S' and E' parameters (P = 0.004 and P = 0.002, respectively). Moreover, diminished E/A ratio of tricuspid valve annulus was related to the increased duration of the disease. Even though left ventricular hypertrophy occurred in the patients, no significant increase was observed in BNP values. Conclusion: The results indicated that M-mode, two-dimensional, pulsed Doppler, and TDI echocardiography might efficiently evaluate cardiac function in patients with preserved ejection fraction. However, BNP measurement might not be useful for screening of cardiac function. [ABSTRACT FROM AUTHOR]

The article discusses medications available to treat diabetes mellitus for children suffering from chronic endocrine disorders. Topics include survey conducted to find methods of alternative treatment, study conducted in Shiraz, Iran where patients enrolled for educational program for management of diabetes, and herbal method was the preferred method of use.

The article discusses the case of a 14 year old girl with diabetes mellitus type 1, who developed generalized edema and pericardial effusion a few days after initiation of insulin therapy. The patient showed no cardiovascular manifestation hence no treatment was prescribed. The case presents a rare case of complication of insulin therapy.
