Item Effect of Health Anxiety on Glycemic Control in Patients with Type Ii Diabetes Mellitus: A Single Center, Cross Sectional Study(2023) Altintas, E.; Bagir, G. Simsek; Haydardedeoglu, F. Eksi; Bag, H.; 37601723Context. Health anxiety was rarely investigated in Type II Diabetes Mellitus (T2DM).Objectives. The present study examines the effect of health anxiety on glycemic control and evaluates factors associated with health anxiety in patients with T2DM according to HbA1c level.Design. Cross-sectional.Subjects and Methods. Socio Demographic Data Form (SDVF), Health Anxiety Inventory-Short Form(SHAI), The Hospital Anxiety and Depression Scale (HADS) were administered to 185 patients with Type II DM . Patients were divided into two groups according to HbA1 c level (HbA1c levels below 7 (Group 1, n=69) and above 7 (Group 2, n=185)). We analyzed prevalence of health anxiety, factors associated with health anxiety between poor and good glycemic control and evaluated of T2DM patients according to health anxiety scale scores. Results. SHAI scale scores were low in 52 (28%), intermediate in 58 (31.2%) and high in 76 (40.8%) of the patients. We found the severity of depressive symptoms was positively correlated with health anxiety in both groups. As a result of this study, there was a relationship between high education and low socioeconomic level, having a job, exercise and anxiety level and low SHAI score in T2DM patients. Depression, stressful life events in the last 6 months were related with high health anxiety. Although the level of health anxiety was not different between groups, low blood sugar levels were related with high health anxiety.Conclusions. This study found that the prevalence of health anxiety in T2DM patients was higher than expected irrespective to poor or good glycemic control, but level of health anxiety in patients with T2DM is not a good predictor for the HbA1c level.Item Previous Gestational Diabetes History is Associated with Impaired Coronary Flow Reserve(2015) Caliskan, Mustafa; Turan, Yasar; Caliskan, Zuhal; Gullu, Hakan; Ciftci, Faika Ceylan; Avci, Enver; Duran, Cevdet; Kostek, Osman; Caklili, Ozge Telci; Koca, Harun; Kulaksizoglu, Mustafa; 0000-0003-2579-9755; 26555575; IXD-5147-2023Background Gestational diabetes mellitus (GDM) is a prediabetic state that is known to increase the risk of cardiovascular diseases. We have investigated coronary flow velocity reserve (CFVR) and epicardial fat thickness (EFT), and left ventricular diastolic function in patients with a history of previous GDM (p-GDM). Methods Ninety-three women with GDM history and 95 healthy women without GDM history were recruited. We used transthoracic Doppler echocardiography to assess CFVR, EFT, and left ventricular diastolic function. Insulin resistance of each subject was assessed with homeostasis model assessment insulin resistance (HOMA-IR). Hemoglobin A1c and high-sensitivity C-reactive protein (hsCRP) were also measured in all patients. Results CFVR values were significantly lower (2.34 +/- 0.39 versus 2.80 +/- 0.24, p<0.001) and EFT values were significantly higher in patients with p-GDM than the control group (5.5 +/- 1.3 versus 4.3 +/- 1.1, p<0.001). E/E' ratio (7.21 +/- 1.77 versus 6.53 +/- 1.38, p = 0.003), hemoglobin A1c (5.2 +/- 0.4 and 5.0 +/- 0.3, p = 0.001), HOMA-IR (2.8 +/- 1.4 versus 1.7 +/- 0.9, p = 0.04), and hsCRP levels were significantly higher in the p-GDM group than the control group. Multivariate analysis revealed that gestational diabetes history is independently associated with CFVR. Conclusion Women with a GDM history may be at more risk regarding coronary microvascular dysfunction compared to the healthy ones.Item Turkish Nationwide Survey of Glycemic and Other Metabolic Parameters of Patients with Diabetes Mellitus (TEMD Study)(2018) Bascil Tutuncu, Neslihan; Bozkirli, Emre; 0000-0002-1816-3903; 0000-0002-1644-6790; 30244051; ABG-5027-2020; E-9887-2014Aims: Turkey has the highest prevalence of diabetes in Europe. It is therefore essential to know the overall cardiovascular risk and reveal the predictors of metabolic control in Turkish adults with diabetes mellitus. Methods: A nationwide, multicenter survey consecutively enrolled patients who were under follow up for at least a year. Optimal control was defined as HbA1c <7%, home arterial blood pressure (ABP) <135/85 mmHg, or LDL-C <100 mg/dL. Achieving all parameters indicated triple metabolic control. Results: HbA1c levels of patients (n = 5211) were 8.6 +/- 1.9% (71 +/- 22 mmol/mol) and 7.7 +/- 1.7% (61 +/- 19 mmol/mol), in Type 1 and Type 2 diabetes, respectively. Glycemic control was achieved in 15.3% and 40.2%, and triple metabolic control was achieved in 5.5% and 10.1%, respectively. Only 1.5% of patients met all the criteria of being non-obese, nonsmoker, exercising, and under triple metabolic control. Low education level was a significant predictor of poor glycemic control in both groups. Conclusions: Few patients with Type 2, and even fewer with Type 1 diabetes have optimal metabolic control in Turkey. TEMD study will provide evidence-based information to policy makers to focus more on the quality and sustainability of diabetes care in order to reduce the national burden of the disease.

Many preclinical and some clinical researches have established some positive effects of gastrin or PPI therapy on glucose regulation. The aim of this study was to prospectively investigate the short term effects of esomeprazole on glycaemic control in patients with type 2 diabetes mellitus. In addition, the presence of an association between this effect and gastrin levels was evaluated. Methods: Thirty-two subjects with type 2 diabetes mellitus were enrolled and grouped as intervention (n=16) and control (n=16). The participants in the intervention group were prescribed 40 mg of esomeprazole treatment for three months. At the beginning of the study and at the 3rd month, HbA1c level (%) and gastrin levels (pmol/L) of participants were assessed. Then, the groups were compared in terms of their baseline and 3rd month values. Results: In the intervention group, the mean gastrin level increased significantly from 34.3 +/- 14.4 pmol/L to 87.4 +/- 43.6 pmol/L (p<0.001). The mean HbA1c level was similar to the pre-treatment level (6.3 +/- 0.7% vs. 6.4 +/- 0.9%, p=0.441). There were no statistically significant differences in all parameters of the control group. The majority of individuals were on metformin monotherapy (65.6 %). The subgroup analysis of metformin monotherapy revealed that, in intervention group, there was a significant increase in gastrin levels (39.9 +/- 12.6 vs. 95.5 +/- 52.5, p=0.026), but the HbA1c levels did not change (6.0 +/- 0.4 % vs. 5.9 +/- 0.6 %, p=0.288); and in control group, gastrin levels did not change (37.5 +/- 26.7 vs. 36.1 +/- 23.3, p=0.367), but there was an increase in HbA1c levels (6.1 +/- 0.50 vs. 6.4 +/- 0.60, p=0.01). Conclusion: Our study demonstrates that esomeprazole has no extra benefit for the controlled diabetic patient in three months. However, in only the metformin-treated subgroup, esomeprazole may prevent the rise in HbA1c level.Item The effects of hyperinsulinemia on cochlear functions(2020) Koca, Arzu Or; Koca, Huseyin Samet; Anil, Cuneyd; 33402607Context: Hyperinsulinemia is the most common metabolic change associated with cochleovestibular diseases. Aim: We aimed to investigate the auditory functions in hyperinsulinemic individuals. Settings and Design: A total of 164 patients were included in this case-control study. While 76 patients with insulin resistance (homeostasis model assessment of insulin resistance [HOMA-IR] of >= 2.5) constituted the case group, 88 patients with HOMA-IR values of <2.5 constituted the control group of the study. Material and Methods: The 75 g oral glucose tolerance test, blood biochemistry tests, hormonal analysis, audiological assessment, electrocochleography (EcochG), and transient evoked otoacoustic emissions (TEOAE) testing were performed. Statistical Analysis: One-way analysis of variance and Kruskal-Wallis analysis of variance were used for the comparison of the metabolic and ear parameters in the normal glucose tolerance (NGT), impaired fasting glucose (IFG), and impaired glucose tolerance (IGT) groups. The chi-square test was used to compare nominal variables. Spearman and Pearson correlation coefficients were used for the correlation analyses of continuous variables. Results: The pure tone audiometry at 0.5, 1, 2, and 4 kHz was better in the case group than in the control group. A positive correlation was found between HbA1c and right ear 0.5, 1, 4, and 8 kHz threshold values and left ear 2, 4, 6, and 8 kHz threshold values. A negative correlation was found between HbA1c and speech discrimination scores. The right ear 1.00 and 2.83 kHz TEOAE measurements in the individuals with NGT were found higher than those in patients with IGT, and the 1.42 kHz TEOAE measurements and reproducibility were found higher than those in patients with IFG. The left ear 1.00 and 1.42 kHz TEOAE measurements of the IGT patients were found lower than those of IFG and NGT patients. Conclusion: We showed that hearing was worsening in hyperinsulinemic patients and prediabetic conditions were related to hearing function impairment.Item Impact of Obesity on the Metabolic Control of Type 2 Diabetes: Results of the Turkish Nationwide Survey of Glycemic and Other Metabolic Parameters of Patients with Diabetes Mellitus (TEMD Obesity Study)(2019) Bascil Tutuncu, Neslihan; Bozkus, Yusuf; Bozkirli, Emre; 30893706Background: Obesity is the main obstacle for metabolic control in patients with type 2 diabetes. Turkey has the highest prevalence of obesity and type 2 diabetes in Europe. The effect of obesity on the metabolic control, and the macro-and microvascular complications of patients are not apparent. Objectives: This nationwide survey aimed to investigate the prevalence of overweight and obesity among patients with type 2 diabetes and to search for the impact of obesity on the metabolic control of these patients. We also investigated the independent associates of obesity in patients with type 2 diabetes. Methods: We consecutively enrolled patients who were under follow-up for at least 1 year in 69 tertiary healthcare units in 37 cities. The demographic, anthropometric, and clinical data including medications were recorded. Patients were excluded if they were pregnant, younger than 18 years, had decompensated liver disease, psychiatric disorders interfering with cognition or compliance, had bariatric surgery, or were undergoing renal replacement therapy. Results: Only 10% of patients with type 2 diabetes (n = 4,648) had normal body mass indexes (BMI), while the others were affected by overweight (31%) or obesity (59%). Women had a significantly higher prevalence of obesity (53.4 vs. 40%) and severe obesity (16.6 vs. 3.3%). Significant associations were present between high BMI levels and lower education levels, intake of insulin, antihypertensives and statins, poor metabolic control, or the presence of microvascular complications. Age, gender, level of education, smoking, and physical inactivity were the independent associates of obesity in patients with type 2 diabetes. Conclusion: The TEMD Obesity Study shows that obesity is a major determinant of the poor metabolic control in patients with type 2 diabetes. These results underline the importance of prevention and management of obesity to improve health care in patients with type 2 diabetes. Also, the results point out the independent sociodemographic and clinical associates of obesity, which should be the prior targets to overcome, in the national fight with obesity.
