BackgroundExcessive weight is a well-known risk factor for microvascular diseases. Changes in thickness in a vascular tissue, such as the choroid, can be useful to evaluate the effect of obesity on the microvascular system. The aim of this study was to evaluate the choroidal thickness (CT) changes in obese women, using optical coherence tomography (OCT).MethodsThe prospective clinical study included examination of the right eyes of 72 patients. The right eyes of 68 patients were examined and served as the controls. A complete ophthalmological examination and OCT imaging were performed for each group studied. The CT in each eye was measured using OCT.ResultsThe obese group consisted of 72 female patients with a mean age of 37.27 ± 1.18 years. The control group included 68 female subjects with a mean age of 37.85 ± 7.98 years (p > 0.05). There was no statistical significant difference for the foveal retinal thickness measurements between the two groups (p > 0.5). Our study revealed significant choroidal tissue thickening subfoveally and at areas 500 μm temporal, 500 μm nasal, and 1500 μm nasal to the fovea in the obese group (all p < 0.05). There was a positive correlation between body mass index (BMI) and CT changes.ConclusionsCT may increase in obese women and a positive correlation was found between BMI and CT.The trial protocol was approved by the Local Ethical Committee of the Kırıkkale University, date of registration: April 27, 2015 (registration number: 10/11).

Mean platelet volume (MPV) is the measure of platelet size. MPV possibly is a simple way to estimate platelet activity. In this study, we aimed to investigate MPV levels in euthyroid Hashimoto's thyroiditis patients. Fifty-one euthyroid patients with Hashimoto's thyroiditis attending our outpatient clinic of the endocrinology department, and 51 age and BMI-matched healthy individuals were included in this study. All patients with euthyroid Hashimoto's thyroiditis were at euthyroid state. None of the study patients was subjected to levothyroxine replacement therapy. Anti-thyroid peroxidase (anti-TPO) antibody and anti-tiroglobulin antibody were positive. All the study participants were evaluated by biochemical and platelet parameters. There were no significant differences in age (33.88 ± 12.87 and 30.18 ± 12.43 years, respectively; P > 0.05) and BMI (23.55 ± 3.34 and 22.25 ± 3.65 kg/m, respectively, P > 0.05) between the study and the control groups. Anti-TPO and anti-tiroglobulin levels were significantly higher in the study group (anti-TPO 428.32 ± 668.39 IU/ml in the euthyroid Hashimoto's thyroiditis group; 14.85 ± 9.66 IU/ml in the control group, P = 0.001; anti-tiroglobulin 320.46 ± 796.05 IU/ml in the euthyroid Hashimoto's thyroiditis group, 21.28 ± 26.24 IU/ml in the control group, P = 0.09). There were no significant differences in terms of serum thyroid-stimulating hormone (TSH) (1.76 ± 0.79 and 1.85 ± 1.14 uIU/ml, respectively), FT3 (3.10 ± 0.37 and 3.29 ± 0.76 pg/ml, respectively) and FT4 (1.22 ± 0.42 and 1.46 ± 0.78 pg/ml, respectively) levels between the study and the control groups. Serum triglyceride levels were significantly higher in the study group than in the control group (133.81 ± 91.50 and 90.18 ± 41.15 mg/dl, respectively; P = 0.015). Mean MPV levels were significantly higher in the euthyroid Hashimoto's thyroiditis group than in the control patients (8.8 ± 1.05 and 7.9 ± 0.79 fl, respectively; P = 0.0001). To assess the correlation with MPV, a Pearson's correlation analysis was performed on each variable. There were positive correlations between anti-TPO and MPV levels (r = 0.246, P = 0.042), and between anti-tiroglobulin and MPV levels (r = 0.256, P = 0.033). The multiple regression analysis of MPV and other risk factors was performed. Age, BMI, C-reactive protein and waist circumference were independent predictive factors of MPV. Adjustment for other factors did not alter these relative risks. Our results suggest that even if in euthyroid state, patients with euthyroid Hashimoto's thyroiditis have higher MPV levels than the healthy controls. As higher MPV levels are closely related with cardiovascular diseases, euthyroid Hashimoto's thyroiditis patients have greater risk of atherothrombotic complications than controls.

The BAEP and fVEP are non-invasive electrophysiologic methods reflecting the integrity or disruption of the central neurologic pathways. The present results confirm the disruption of the central nervous system with the BAEP in children with protein-energy malnutrition, especially in kwashiorkor patients.

Although GH and IGF-1 levels were increased in acromegalic patients, no significant difference was found in terms of vertebral BMD. Only hip t‑scores were found to be lower in acromegalic patients, but this low hip t‑score did not reach the osteopenic level. The positive correlation between IGF-1 and lumbar vertebral BMD suggested a more prominent effect of IGF-1 on BMD compared to GH.

Recently, it has been remarked that dietary fatty acids and fatty acid receptors might be involved in the aetiology of diabetes. Therefore, this study was conducted to determine the relationship between dietary fatty acid pattern, fatty food preferences and soluble CD36 (sCD36) and insulin resistance in type 2 diabetes mellitus (DM). The study was carried out with thirty-eight newly diagnosed type 2 DM patients and thirty-seven healthy volunteers, aged 30-65 years. In the study, socio-demographic characteristics, dietary fat type and fatty acid pattern of individuals were recorded. After anthropometric measurements were taken, blood CD36, glucose, TAG and insulin levels were analysed. The results showed that although the type of fatty acid intake did not differ between the groups (P>0·05), the consumption of olive oil in the type 2 DM group was lower than the control group (P0·05). Crucially, elevated sCD36 levels increased the type 2 DM risk (OR 1·21, P<0·05). In conclusion, sCD36 level may be a possible biomarker, independent from the dietary fatty acid pattern, for type 2 DM owing to its higher levels in these patients. Therefore, the new insights make CD36 attractive as a therapeutic target for diabetes.

We studied Stem cell factor (SCF) levels in 15 mother-newborn pairs, 15 healthy adult controls, and 16 newborn with bacterial sepsis. SCF levels were also determined in six newborns with sepsis before and after completion of treatment. SCF levels (pg/mL) were found to be 2141 +/- 529 in cord blood, 1385 +/- 314 in mothers, 1546 +/- 443 in healthy adult controls, and 1742 +/- 655 in septic newborns. Cord blood SCF levels were significantly higher than their mothers' and healthy controls (p < 0.05). There were no differences in SCF levels between mothers and healthy adult controls. No correlation was found between the SCF levels and absolute neutrophil counts. There were no differences in SCF levels between the before and after treatment levels in six newborn with sepsis. In conclusion, our study suggests that SCF levels were increased in cord blood, and this increase is not a reflection of mothers' levels. SCF levels do not show significant changes during sepsis in newborns.
