    (2014) Duran, Ayse Ocak; Anil, Cuneyd; Gursoy, Alptekin; Nar, Asli; Altundag, Ozden; Inanc, Mevlude; Bozkurt, Oktay; Tutuncu, Neslihan Bascil; https://orcid.org/0000-0003-3802-9733; https://orcid.org/0000-0003-0998-8388; https://orcid.org/0000-0003-0197-6622; https://orcid.org/0000-0002-1816-3903; 24338169; AAA-2743-2021; W-9219-2019; ABG-5027-2020
    The present retrospective study aimed to investigate the relationship between thyroid volume and prevalence of thyroid cancer. We investigated the data of 3,850 patients who underwent fine-needle aspiration biopsy (FNAB). Biopsy results were evaluated as diagnostic or nondiagnostic, and diagnostic results were classified as benign, malignant, and indeterminate. We included 2,672 patients who underwent FNAB firstly in our hospital and evaluated as diagnostic biopsy except subgroup of indeterminate. We obtained cytologic data, levels of serum thyroid-stimulating hormone (TSH), and thyroid volumes of those patients retrospectively. Among 2,672 patients with thyroid nodule, 2,562 (95.9 %) patients had benign cytology and 110 (%4,1) patients had malignant cytology. There was no correlation between the malignancy and gender (p = 0.935), and patients with malignant cytology were younger (52 vs 59, p < 0.001). Also, TSH levels were higher in patients with malignant than benign cytology (p = 0.017). Median volume of right part, left part, and total thyroid for patients who had malignant cytology was significantly lower than patients who had benign cytology (8.3, 7.1, 15.9 vs 10.8 ml, 9.0 mml, 20.6 ml, respectively, p <= 0.001 for all parameters). The results demonstrated that thyroid cancer prevalence was higher in patients with low thyroid volume. According to our results, thyroid volume should be considered as a risk factor for malignancy in the evaluation of thyroid nodules.

    Association of Body Mass Index with Depression and Alexithymia
    (2014) Karagol, Arda; Ozcurumez, Gamze; Taskintuna, Nilgun; Nar, Asli; https://orcid.org/0000-0002-3548-5517; https://orcid.org/0000-0003-0998-8388; ABE-8882-2020; AAK-3556-2021; AAA-2743-2021
    Objective: Association between body mass index (BMI) and mental disorders had long been investigated. Recent researches declare a relation between obesity and depressed mood as well as clinical depression. On the other hand mental disorders such as alexithymia are also found to be correlated with an increased risk of obesity. Therefore we aimed to evaluate depression and alexithymia together among normal, overweight and obese adults in order to assess what kind of an association is there between BMI, depression and alexithymia. Methods: We enrolled 100 adults, aged between 18 to 67 from department of endocrinology outpatient clinic whom had normal levels of TSH, fT3 and fT4 thyroid hormones and formed three groups according to their Body Mass Index (BMI). Individuals who had had BMI between 18.5 and 24.99 formed the normal, BMI between 25 and 29.99 formed the overweight and BMI 30 and above formed the obese groups. All three groups were evaluated by Composite International Diagnostic Interview for clinical diagnosis and also given Toronto Alexithymia Scale-26 item (TAS-26) as well as Beck Depression Inventory (BDI). Results: There was a positive relation between BMI and current depressive episode and this finding was stronger in women. There was no such relation with lifelong depression. TAS-26 total and subscale scores revealed no difference between three groups. As BDI total scores got higher TAS-26 scores were higher. Hence there was a strong positive relation between depression and alexithymia. Conclusion: Our findings indicate that higher BMI increases current depressive episode. No association is found between BMI and lifelong depression. Depression and depression severity are strongly associated with alexithymia. Contradictive with literature, alexithymia and its severity are not found to be related with BMI. Following overweight and obese individuals is important to offset the adverse outcomes of depression.

    Acoustic Radiation Force Impulse Elastography and Ultrasonographic Findings of Achilles Tendon in Patients With and Without Diabetic Peripheral Neuropathy: A Cross-Sectional Study
    (2021) Iyidir, Ozlem Turhan; Rahatli, Feride Kural; Bozkus, Yusuf; Ramazanova, Lala; Turnaoglu, Hale; Nar, Asli; Tutuncu, Neslihan Bascil; 0000-0001-5305-6807; 0000-0002-6976-6659; 0000-0003-0998-8388; 0000-0002-1816-3903; 30786314; K-7904-2019; AAA-5419-2021; AAA-2743-2021; ABG-5027-2020
    Aims We aimed to evaluate the elastographic features of Achilles tendon with Acoustic Radiation Force Impulse in patients with and without diabetic neuropathy. Methods According to the presence of peripheral neuropathy, 45 patients with type 2 diabetes were divided into 2 subgroups. Those with peripheral neuropathy were defined as group I (22 patients) and those without peripheral neuropathy were defined as group II (23 patients). A total of thirty age-, gender-, and body mass index-matched healthy individuals were selected as controls. All participants underwent both ultrasonographic and Acoustic Radiation Force Impulse elastographic examination in order to evaluate Achilles Tendon thickness and stiffness. Results Achilles tendon thicknesses were similar between groups (p = 0.991). Achilles tendon thicknesses of both patient groups were significantly higher than the control group (group I vs control p = 0.01; group II vs control p = 0.006). Stiffness values of Achilles tendons were similar between the control group and group II (p = 0.993). Shear Wave Velocity was significantly lower in group I than group II and control group (p < 0.001). Conclusion Diabetic patients with neuropathy have thicker and softer Achilles tendon while the elasticity of Achilles tendon in diabetic patients without neuropathy is similar to the healthy controls. Softening of the Achilles tendon may be an early sign of diabetic foot and reveal the patients with a risk of diabetic foot.

    Short-Term Effect of Hypergastrinemia Following Esomeprazole Treatment On Well-Controlled Type 2 Diabetes Mellitus: A Prospective Study
    (2020) Bozkus, Yusuf; Mousa, Umut; Iyidir, Ozlem T.; Kirnap, Nazli; Demir, Canan C.; Nar, Asli; Tutuncu, Neslihan B.; 0000-0002-1816-3903; 0000-0002-6976-6659; 0000-0002-8078-9376; 0000-0001-5305-6807; 0000-0003-0998-8388; 31995024; ABG-5027-2020; AAA-5419-2021; AAK-4857-2021; I-1735-2018; K-7904-2019; AAA-2743-2021
    Objective: Proton pump inhibitor (PPI) drugs reduce gastric acid secretion and lead to an increase in serum gastrin levels. 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.
