Abstract
Permanent Scatterers (PS) point velocities obtained by the interferometric synthetic aperture radar (InSAR) method are generally determined using the linear regression model, which ignores periodic and seasonal effects. In this study, software was developed that can detect periodic effects by applying fast Fourier transformation (FFT) time series analysis to InSAR results. Using the FFT time series analysis, the periodic components of the surface movements at the PS points were determined, and then the annual velocity values free from periodic effects were obtained. The study area was chosen as the Gediz Graben, a tectonically active region where aseismic surface deformations have been observed in recent years. As a result, using the developed method, seasonal effects were successfully determined with the InSAR method at the PS points in the study area with a period of 384 days and an average amplitude of 19 mm. In addition, groundwater level changes of a water well in the region were modeled, and 0.93 correlation coefficient values were calculated between seasonal InSAR displacement values and water level changes. Thus, using the developed methodology, the relationship between the tectonic movement in the Gediz Graben in Turkey and the seasonal movements and the change in the groundwater level was determined.

Abstract
BackgroundSystemic sclerosis (SSc) is a heterogeneous autoimmune disease, with a high disease-related mortality and morbidity. A subset of patients show elevated CRP levels (20-35%), which has been reported as inflammatory SSc. Preliminary data suggest that this subset is characterized by a severe phenotype.ObjectivesTo analyse the phenotype and the survival of inflammatory compared with non-inflammatory SSc patient subsets.MethodsData from 8571 SSc patients with available CRP measurement from the EUSTAR cohort were analysed. Exclusion criteria included acute infection, missing follow-up and tocilizumab treatment. Patients with a CRP ≥5mg/l at ≥80% of visits were stratified as persistent inflammatory and as non-inflammatory if CRP was ≥5 mg/l at <20% of visits (as described previously (1)). As a sensitivity analysis, patients were defined as inflammatory and non-inflammatory based on a single CRP measurement at baseline only (CRP ≥5 or <5mg/l, respectively). We compared baseline characteristics using Chi-square and non-parametric Kruskal–Wallis tests as appropriate. Kaplan Meier curves with log-rank tests were used to estimate time from baseline to death or censoring, and Cox regression to compare mortality risks adjusted for time from diagnosis to baseline.ResultsOut of 2883 patients with more than two visits, 404 (14%) showed persistent inflammation and 1032 (36%) a non-inflammatory phenotype. Out of 5619 patients with more than one visit, 1830 (33%) were stratified as inflammatory as defined by as single CRP measurement at baseline and 3789 (67%) as non-inflammatory. With both definitions, the inflammatory subset revealed a more severe phenotype than non-inflammatory patients, including more frequent diffuse-cutaneous disease, anti-Scl-70 autoantibodies, pulmonary fibrosis, pulmonary hypertension, higher modified Rodnan skin score, and lower forced vital capacity and diffusing capacity for carbon monoxide. Patients with persistent inflammation had a strongly increased risk of all-cause mortality (HR 7.1 [95%CI 3.7 to 13.5], p<0.001) compared to non-inflammatory patients, whereas this association was weaker when based on a single CRP measurement (HR 2.6 [95%CI 2.1 to 3.2], p<0.001).ConclusionThe severe phenotype and decreased survival of the inflammatory SSc subset, which was most prominent in patients with persistently elevated CRP levels, suggest a distinct disease subset. Therefore both, the need for more regular monitoring of inflammatory parameters and implications for immune-modulating treatment, needs to be carefully analysed.References[1]Mitev, A., et al., Inflammatory stays inflammatory: a subgroup of systemic sclerosis characterized by high morbidity and inflammatory resistance to cyclophosphamide.

Abstract
OBJECTIVE To investigate the relationship between thyroid functions and asymmetric dimethylarginine (ADMA), ischemia-modified albumin (IMA), and other metabolic laboratory markers in euthyroid adults and whether narrower thyroidal targets are required for lower metabolic risk. MATERIALS AND METHODS Thyroid functions, antithyroid autoantibodies, and metabolic parameters were measured for 115 patients. Forty-seven had autoimmune thyroiditis (AIT). Analyses were performed according to cutoff values of 1, 2, 2.5, and 3 mIU/L for thyrotropin, 0.84 ng/dL for free thyroxine (fT4), and 3.59 ng/dL for free tri-iodothyronine (fT3). RESULTS There was no relationship between thyrotropin and fT3 cutoff values and metabolic parameters. Only C-reactive protein was lower in the group with thyrotropin ≤2.5 μIU/L. A weak positive correlation was found between fT4 with IMA and IMA corrected for albumin (r = 0.187, P = .05; r = 0.204, P = .034, respectively). There was no difference between AIT and the metabolic laboratory parameters examined in the study. CONCLUSION This study is the first to evaluate ADMA in AIT. Narrower thyroid function targets are not required for better metabolic control in euthyroid adults.

Abstract
INTRODUCTION Metabolic syndrome (MetS) is defined as an association between diabetes, hypertension, obesity and dyslipidemia and an increased risk of cardiovascular disease. Mitral annular calcification (MAC) is associated with several cardiovascular disorders, including coronary artery disease, atrial fibrillation (AF), heart failure, ischemic stroke and increased mortality. The CHA2DS2-VASc score is used to estimate thromboembolic risk in AF. However, the association among MAC, MetS and thromboembolic risk is unknown and was evaluated in the current study. METHODS The study group consisted of 94 patients with MAC and 86 patients with MetS. Patients were divided into two groups: those with and those without MAC. RESULTS Patients with MAC had a higher MetS rate (P<0.001). In patients with MAC, the CHA2DS2-VASc scores and the rate of cerebrovascular accident and AF were significantly higher compared to those without MAC (P<0.001, for both parameters). The results of the multivariate regression analysis showed that history of smoking, presence of MetS and high CHA2DS2-VASc scores were associated with the development of MAC. ROC curve analyses showed that CHA2DS2-VASc scores were significant predictors for MAC (C-statistic: 0.78; 95% CI: 0.706-0.855, P<0.001). Correlation analysis indicated that MAC was positively correlated with the presence of MetS and CHA2DS2-VASc score (P=0.001, r=0.264; P<0.001, r=0.490). CONCLUSION We have shown that CHA2DS2-VASc score and presence of MetS rates were significantly higher in patients with MAC compared without MAC. Presence of MAC was correlated with CHA2DS2-VASc score, presence of MetS, AF and left atrial diameter and negatively correlated with left ventricular ejection fraction.

Abstract
INTRODUCTION Vitamin D deficiency is a common problem, and it is related to increased risk of obesity, metabolic syndrome, atherosclerosis, and cardiovascular disease. Vitamin D has a beneficial effect on dyslipidemia and insulin secretion. We aimed to investigate the impact of vitamin D3 supplementation on anthropometric and laboratory parameters in overweight and obese premenopausal women. MATERIAL AND METHODS Seventy-two overweight and 50 obese vitamin-D-deficient premenopausal women (mean age: 43.1 ±10.4 years) were included in the study. Baseline mean 25-hydroxyvitamin D [25(OH)D] level was 6.1 (min.-max. = 2.9-15.8) ng/ml in overweight and was 5.6 (min.-max. = 3.0-22.0) ng/ml in obese subjects. At baseline and at the sixth month of supplementation, serum 25(OH)D, intact parathormone (iPTH), calcium, phosphorus, homeostasis model assessment of insulin resistance (HOMA-IR), and lipid profiles were assessed. RESULTS Following vitamin D3 supplementation in overweight and obese subjects, serum 25(OH)D increased from 6.1 to 34.7 ng/ml and 5.6 to 34.7 ng/ml, respectively (p < 0.001). At the sixth month of supplementation in both overweight and obese subjects, a significant reduction was detected in HOMA-IR (p < 0.001), low-density lipoprotein cholesterol (LDL-C) (p = 0.046, p = 0.044; respectively) and iPTH levels (p ≤ 0.001, p < 0.001; respectively). A negative adjusted correlation was found between changes in 25(OH)D and HOMA-IR (r = -0.581, p < 0.001; r = -0.389, p = 0.005; respectively). A 1 ng/ml increase in serum 25(OH)D level led to a 0.30-fold reduction in HOMA-IR level (p = 0.002). CONCLUSIONS Our results support the effect of vitamin D3 supplementation in HOMA-IR and LDL-C improvement in both obese and overweight subjects. Further studies focused on low serum 25(OH)D levels with insulin resistance and dyslipidemia are needed.

Abstract
Objective To evaluate the predictive value of epicardial fat thickness (EFT) in
CHA2DS2-VASc (congestive heart failure,
hypertension, age ≥75 years, diabetes mellitus, previous stroke or
transient ischemic attack, vascular disease, age 65-74 years, sex category)
score risk groups. Methods A total of 158 consecutive patients (75 females, 83 males, mean age
70.8±6.3 years) admitted routinely for cardiologic control were
divided into two groups according to their
CHA2DS2-VASc scores (scores 0 and 1 were regarded as
low risk, and score ≥2 as high risk). One hundred twenty-five of 158
patients had a high-risk score. Results Mean EFT was significantly higher in the high-risk group than in the low-risk
group (4.34±0.62 vs. 5.37±1.0;
P<0.001). EFT was positively correlated with
CHA2DS2-VASc score (r=0.577,
P<0.001). According to receiver operating
characteristics (ROC) analysis, EFT value of 4.4 mm was found to be
predictive of high risk in CHA2DS2-VASc score with 80%
of sensitivity and 79% of specificity (C-statistic = 0.875,
P<0.001, 95% confidence interval [CI] = 0.76-0.90).
And according to multivariate logistic regression analysis, EFT was an
independent predictor of high thromboembolic risk in terms of
CHA2DS2-VASc score. Conclusion Our findings suggest that echocardiographic EFT measurement could provide
additional information on assessing cardiovascular risks, such as
thromboembolic events, and individuals with increased EFT should receive
more attention to reduce unfavorable cardiovascular risk factors and the
development of future cardiovascular events.

Abstract
Background Mitral annular calcification (MAC) is associated with several cardiovascular disorders including coronary artery disease (CAD), atrial fibrillation, heart failure, ischemic stroke and increased mortality. Epicardial fat thickness (EFT) has strong correlation with obesity, CAD, insulin resistance, metabolic syndrome, hypertension, diabetes mellitus, and atherosclerosis. There are strong similarities between EFT and MAC from the aspect of risk factors and pathogenesis. Objective In this study we aimed to investigate the EFT in patients with MAC. Methods The study group consisted of 78 patients with MAC. An age, gender and body mass index matched control group consisted of 47 subjects who admitted to echocardiography laboratory due to suspicion of organic heart disease and eventually found to be free of MAC. We measured EFT in patients with MAC and control subjects. Results EFT was significantly higher in patients with MAC than in control subjects (5.7±0.9 vs. 4.4±0.6 mm respectively; P< 0.001). Correlation analysis indicated that EFT was positively correlated with presence of MAC (p<0.001, r=0.597). Conclusion We showed that EFT was significantly elevated in patients with MAC and it was positively correlated with MAC.

Abstract
Open and distance education, unlike the traditional style of education, does not have to come to the campus, courses are processed in a completely virtual environment through the computer, live and interactive is the name of the training that the participant can watch them again and again at any time. Open and distance education in this aspect; Student Centre is an ideal educational model for people who cannot benefit from traditional education, providing equal opportunities, providing education opportunities for physically disabled students, eliminating geographical and regional barriers. Besides, it is a modern and innovative education model that ensures the continuation of the education of the people working in their businesses. Career compliance is a process that starts from preparation for the profession and starts from employment, progress in career and ending a career. Career compliance reflects an individual’s capacity to cope with potential changes that may arise in the present and future business life. Besides, employees’ level of coping with new job responsibilities, unexpected career changes and the ability to overcome obstacles that may arise. The main purpose of this study is to examine the relationship between education satisfaction levels and career adaptability perceptions of participants taking education within open or distance education model. The study is important in terms of developing and improving the open or distance education model when considering that the number of people taking education within the open or distance education model in our country is more than three and a half million today. Besides, one of the important issues in working life in contemporary societies is the career issue and it is thought that the adaptability of employees with their occupations has an important role in their productivity. Therefore, determining the level of educational satisfaction and career adaptability is thought to be important. In the study, which is based on «lifelong learning theory», the quantitative research method was preferred. To collect data, the «Distance Education Satisfaction Scale» and the «Career-related Adoptability» scales were employed. Data collected from a sample of 527 individuals were analysed by difference, relationship and impact tests and it was found that distance education satisfaction had a positive effect on career adaptability.
Keywords: education satisfaction, career adaptability, distance education, open education, e-learning.

Abstract
OBJECTIVE We aimed to investigate the effects of oxidative stress in the pathogenesis and progression of Hashimoto's thyroiditis (HT). METHODS Forty euthyroid and 40 subclinical hypothyroid patients older than 18 years and not yet had received treatment were enrolled in the study. RESULTS In the 9 months follow-up, 14 of the HT patients developed overt hypothyroidism. The mean total oxidant status (TOS) and oxidative stress index (OSI) were higher in patients who developed overt hypothyroidism than those who did not (p < .001). And no significant difference was found between the two groups in terms of paraoxanase-1 and arylesterase (p > .05). Multivariable Cox regression model showed thyroid stimulating hormone level (HR = 1.348, p < .001), free-thyroxine level (HR = 0.481, p = .017) and OSI ratio (HR = 2.349, p < .001) to be independent predictors of development of overt hypothyroidism. OSI level, being over 2.96 with 92.9% sensitivity and 62.5% specificity, predicts the risk of hypothyroidism. CONCLUSION Oxidative stress may be an effective risk factor in the development of overt hypothyroidism in HT.

Abstract
INTRODUCTION Thyroid dysfunction is among the most common autoimmune disorders in women of reproductive age. Previous studies have shown the association between autoimmune thyroid disease (AITD) and infertility. Anti-Müllerian hormone (AMH) is secreted by granulosa cells and is a useful marker for assessment of ovarian reserve. In the present study, we sought to evaluate the ovarian reserves of women with autoimmune thyroid disorder by measurement of AMH values. MATERIAL AND METHODS This prospective study included women with newly diagnosed AITD aged between 20 and 40 years. Patients were divided into three groups: subclinical hypothyroidism (SCH, n = 21), overt hypothyroidism (OH, n = 21) and controls (CG, n = 32). Study parameters included serum free T4, free T3, thyroid-stimulating hormone, anti-thyroglobulin, anti-thyroid peroxidase antibodies, follicle-stimulating hormone, luteinizing hormone, estradiol and AMH concentrations measured in the early follicular phase. Antral follicle count (AFC) was assessed with ultrasound. Body mass index (BMI) and waist circumference of the patients were noted. RESULTS No significant difference was found among SCH, OH and CG in regard to ovarian reserves measured by AMH values (p = 0.19) and AFC (p = 0.80). A significant negative correlation was found between AMH and BMI (r = -0.382, p = 0.001). Anti-Müllerian hormone and waist circumference (r = -0.330, p = 0.004) were also negatively correlated. CONCLUSIONS Although AMH values were not significantly different among groups, AMH values were lower in OH and SCH patients, indicating a possible need for close monitoring of these patients.

Abstract
OBJECTIVE The aim of the present study was to determine the irisin levels in patients with the type 1 diabetes mellitus (T1DM) and to examine the relation of irisin levels with the inflammation and autoimmunity. METHODS This study included 35 cases diagnosed with T1DM and 36 healthy volunteers. Antiglutamic acid decarboxylase (anti-GAD), islet cell antibody (ICA), and insulin autoantibody levels were measured in patients at the time when they were included into the study and recorded from the patient files. Serum irisin levels were measured by ELISA kit. RESULTS The median irisin levels were determined higher in T1DM group compared to the control one (6.8 ng/ml vs. 4.8 ng/ml, p=0.022; respectively). Median irisin levels were higher in anti-GAD (p=0.022) and ICA (p=0.044) positive groups compared to negative groups. In T1DM group, irisin levels displayed positive correlation with glycosylated hemoglobin (HbA1c) (r=0.377, p<0.001) and anti-GAD (r=0.392, p=0.020) and negative correlation with creatinine (r=-0390, p=0.021). In multivariate regression model, HbA1c (B±SE: 2.76±17683, p<0.001), and anti-GAD (B±SE: 2.311±0.610, p=0.001) were determined as independent predictors for predicting the irisin levels. CONCLUSION In patients with T1DM, which chronic inflammation and autoimmunity take part in their etiopathogenesis, anti-GAD levels were an independent risk factor for the irisin. Th is may suggest that factors such as inflammation and autoimmunity can be effective in the synthesis of irisin.

Abstract
Adrenal incidentalomas (AIs) are usually discovered incidentally after imaging unrelated to adrenal glands. We aimed to evaluate standard risk factors for systemic atherosclerosis and echocardiographic changes in patients with nonfunctioning AIs and compare them with normal subjects. We evaluated 70 patients diagnosed with AIs and 51 healthy controls. Mean levels were determined for HbA1c, LDL, uric acid, fasting plasma insulin, HOMA, and neutrophil-to-lymphocyte ratio (NLR), and these values were found to be significantly higher in the patients than the controls. The mean left atrial diameter, interventricular septum thickness, posterior wall thickness, left ventricular mass, E-wave deceleration time, isovolumetric relaxation time, and the median ratio of the early transmittal flow velocity to the early diastolic tissue velocity (E/Em) were higher in patients with AIs compared to controls. The mitral annular early diastolic velocity was lower in patients with AIs. The mean aortic diastolic diameter, stiffness index (SI), and aortic strain were higher, and aortic distensibility was lower in the patients. The mean right ventricular diameter, right atrial major-axis diameter, and right atrial minor-axis diameter were statistically higher in the patient group than the controls. A negative correlation was found between the NLR and aortic strain and aortic distensibility, while a positive correction was found between the NLR and SI. We found altered left ventricular (LV) and right ventricular (RV) echocardiographic findings in patients with AIs without known cardiovascular disease. Aortic stiffness was also increased. These changes may be related to an increase in cardiovascular risk factors in AI patients.

Osteoporosis and Silent Vertebral Fractures in Nursing Home Resident Elderly Men in Turkey. J Clin Densitom 2017; 20:188-195. [PMID: 26071170 DOI: 10.1016/j.jocd.2015.05.064] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/15/2015] [Revised: 04/20/2015] [Accepted: 05/06/2015] [Indexed: 01/22/2023]
Abstract
Osteoporosis is an important cause of vertebral fractures and there is an increased risk for osteoporosis in nursing home residents. Most of the men with osteoporosis and osteoporotic fractures are not diagnosed and do not receive treatment. Our study aim was to determine osteoporosis and silent vertebral fracture prevalence in male nursing home residents in Corum, Turkey. This cross-sectional study included 2 groups of patients: 71 male nursing home residents (nursing home group) with a mean age of 76.0 ± 0.8 years and 44 men living in their own homes (control group) with a mean age of 74.4 ± 0.7 years. Bone mineral densitometry was performed in all subjects, and results were evaluated according to the World Health Organization criteria. Vertebral deformity was evaluated using the spinal deformity index, and fracture risk was calculated using the Fracture Risk Assessment Tool. In all participants, serum calcium, phosphorus, 25 (OH) vitamin D, parathyroid hormone, and alkaline phosphates levels were measured and medical histories were recorded. Osteoporosis was detected in 25.3% of men residing in nursing homes and in 8.8% of men living in their own homes. Silent vertebral fracture was present in 27.8% of patients older than 65 years. Vertebral fracture rate was higher in nursing home residents (42.2%) than men living in their own homes (17.6%); 5.6% of nursing home group and 8.9% of control group patients were aware of their fractures. Our results demonstrated that male nursing home residents are at a higher risk for both osteoporosis and vertebral fractures compared to the men living in their own homes.

Abstract
INTRODUCTION Gestational diabetes mellitus (GDM) occurs in ∼10-25% of pregnancies. Nesfatin-1, plays a role in carbohydrate metabolism by inhibiting glucagon secretion, besides has a glucose-dependent insulinotropic effect. Explanation of the GDM pathogenesis is important due to preventing gestational complications. We aimed to investigate relationship between GDM and Nesfatin-1. MATERIAL AND METHODS Seventy-nine pregnant subjects were randomly allocated to either GDM group (GDG, n = 38) or control group (CG, n = 41). For GDM diagnosis, 50 and 100 g oral glucose tolerance test (OGTT) were used. Nesfatin-1, insulin and other parameters were measured for all subjects. The homeostasis model assessment-insulin resistance (HOMA-IR) was calculated. RESULTS Nesfatin-1 was found lower and insulin was found higher in GDG than CG. Negative correlation has been founded between Nesfatin-1 with weight, BMI, fasting glucose, serum glucose level at first hour of the 50 g OGTT and HOMA-IR. CONCLUSION In this study, patients with GDM had lower Nesfatin-1 levels than without GDM. Therefore, when the Nesfatin-1 effects on the GDM pathogenesis is clear, it may be contributed to diagnosis and treatment of the GDM.

Abstract
OBJECTIVE Hashimoto's thyroiditis (HT) may affect metabolic parameters and increase predisposition to obesity. In this study, we aimed to assess the relationships among serum ghrelin concentrations, metabolic parameters, and thyroid autoimmunity in euthyroid HT patients. METHODS The study included 48 euthyroid HT patients and 41 age- and sex-matched healthy controls. We assessed serum ghrelin, free triiodothyronine (T3), free thyroxine (T4), thyroid-stimulating hormone (TSH), thyroid peroxidase antibody (anti-TPO), thyroglobulin antibody (anti-Tg), fasting blood glucose (FBG), insulin, lipid levels, and homeostasis model assessment insulin resistance (HOMA-IR) in all subjects. RESULTS Sex distribution, mean age, and body mass index (BMI) were similar in HT patients and controls (female/male, 42/6 vs. 33/8, 46.8 ± 14.7 vs. 45 ± 12.5 years, 28.5 ± 6.1 vs. 28.4 ± 4.9 kg/m2, respectively; P>.05 for all). The mean waist circumference (WC) of the HT group was significantly higher than that of the control group (100.6 ± 14.6 vs. 93.2 ± 13.2 cm, P = .015). While FBG, low-density lipoprotein cholesterol (LDL-C), and triglyceride levels in the HT group were significantly higher than in the control group, insulin levels and HOMA-IR were similar. Ghrelin levels were lower in HT patients compared to controls (416.9 ± 224.4 and 689.9 ± 191.6 pg/mL, respectively; P<.001). Ghrelin levels were similar in patients with low and high anti-TPO titers. Negative correlations were observed between ghrelin levels and BMI, WC, and anti-TPO levels. Regression analysis revealed that HT was the most important predictor of ghrelin levels. CONCLUSION Euthyroid HT is associated with a decrease in plasma ghrelin levels. Altered body fat distribution and increased anti-TPO levels do not seem to be directly involved in lower ghrelin levels in euthyroid HT patients.

The Relationship Between Increased Epicardial Fat Thickness and Left Ventricular Hypertrophy and Carotid Intima-Media Thickness in Patients With Nonfunctional Adrenal Incidentaloma. Int J Endocrinol Metab 2016; 14:e37635. [PMID: 27942264 PMCID: PMC5138281 DOI: 10.5812/ijem.37635] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/06/2016] [Revised: 06/15/2016] [Accepted: 06/26/2016] [Indexed: 01/19/2023] Open
Abstract
BACKGROUND Emerging evidences indicate that patients diagnosed with Adrenal Incidentaloma (AI) may present cardiovascular complications. Epicardial fat thickness (EFT) has recently been described as a new risk factor and an active player in metabolic syndrome and cardiovascular disease. OBJECTIVES We aimed to evaluate the relationship between EFT and left ventricular hypertrophy and carotid intima-media thickness, which are both strong predictors of cardiovascular morbity and mortality, in patients with nonfunctioning AI. PATIENTS AND METHODS We evaluated 51 patients (36 females and 15 males) diagnosed with AI and 35 (29 females, 6 males) age, gender and body mass index (BMI) matched healthy controls in terms of cardiovascular risk parameters. Epicardial fat was identified as the echo-free space between the outer wall of the myocardium and the visceral layer of the pericardium. RESULTS Epicardial fat thickness was significantly higher in patients with AI when compared to the control group (0.89 ± 0.32 cm vs. 0.74 ± 0.26 cm; P = 0.023). left ventricular (LV) mass index and median carotid intima-media thickness (CIMT) were also higher in subjects with AI than in controls (99.8 g/m2 vs. 86.9 g/m2; P = 0.024 and 7.5 mm (5.5 - 11.5) vs. 6.5 mm (4.5 - 9.5); P = 0.017). There was a positive correlation between EFT, LV mass index, EFT and CIMT (r = 0.315, P = 0.004; r = 0.363, P < 0.001; respectively). CONCLUSIONS In this study we showed that EFT, measured by echocardiography is higher in subjects with AI when compared to healthy controls. epicardial fat thickness had the best independent correlation with AI in multiple logistic regression analysis. Incidentaloma is also associated with increased left ventricular mass index and CIMT. Adrenal incidentaloma patients may show early cardiac changes, such as increased left ventricular mass and increased CIMT.

Abstract
BACKGROUND Hyperprolactinemia is the most common endocrinologic disorder in causing menstrual irregularities. Although the correlation between hyperprolactinemia and menstrual dysfunction is widely known, the etiology of menstrual cycle disorders is not profoundly understood in patients with prolactinoma. We aimed to investigate the correlation between prolactin levels and insulin resistance and hyperandrogenism in patients with prolactinoma. METHODS Sixty-four patients with microprolactinoma and 33 healthy women were enrolled. Thirty-six of these patients with prolactinoma (group 1) had an estradiol (E2) level under 30 pg/mL, and 28 (group 2) had an E2 level greater than 30 pg/mL. Blood samples were drawn to measure the levels of the following hormones: Follicle stimulating hormone (FSH), luteinizing hormone (LH), E2, prolactin (PRL), total testosterone (TT), androstenedione (AS) and dehydroepiandrostenedione sulphate (DHEAS). Body Mass Index (BMI of ≥30 kg/m2) was excluded from the study. Insulin resistance (IR) was calculated by the HOMA-IR. RESULTS BMI was higher in patients with prolactinoma than the control group (P=0.02, P=0.025, respectively). IR and glucose intolerance existence were higher in patients with prolactinoma (P=0.007, P=0.097, respectively) than the healthy women, but these differences did not exist between eugonadic and hypogonadic women with prolactinoma (P=0.020, P=0.032, respectively, Bonferroni correction). TT and AS were higher in eugonadic women with prolactinoma than the control group (P=0.004, P=0.003, Bonferroni correction, respectively). CONCLUSIONS Our study revealed that the relationship between hyperprolactinemia and IR/glucose intolerance is irrespective of gonadal status in women with prolactinoma. Also, the study concluded that hyperandrogenism may be a cause of menstrual dysfunction in eugonadic women with prolactinoma.

The impact of levothyroxine sodium treatment on oxidative stress in Hashimoto's thyroiditis. Eur J Endocrinol 2016; 174:727-34.

Abstract
OBJECTIVE Although several studies reported increased oxidative stress in Hashimoto's thyroiditis (HT), the effect of levothyroxine treatment on oxidative status is not studied extensively. Therefore, we conducted this study to investigate the effects of levothyroxine replacement on oxidative stress in HT. DESIGN AND METHODS Thirty-six patients recently diagnosed with HT-related hypothyroidism and 36 healthy controls were included in the study. Levothyroxine replacement was started to patients with hypothyroidism, and had been followed-up for 6 months. RESULTS Mean basal serum total antioxidant status (TAS), total thiol, arylesterase, and paraoxonase 1 (PON1) levels were significantly lower, and serum total oxidant status (TOS) and oxidative stress index (OSI) were significantly higher in the patients with hypothyroid than the controls. In the hypothyroid group serum TAS, total thiol, arylesterase, and PON1 levels increased and serum TOS and OSI levels decreased significantly after levothyroxine treatment. Pretreatment serum TAS, total thiol, PON1, and arylesterase levels were positively correlated with free levothyroxine (fT4) and negatively correlated with thyroid-stimulating hormone (TSH), antithyroid peroxidase (anti-TPO), and antithyroglobulin (anti-TG) levels. Also, pretreatment serum TOS and OSI levels were negatively correlated with fT4 levels and positively correlated with TSH, anti-TPO, and anti-TG. We have also found that the fT4 and anti-TPO levels are independent predictors of the oxidative stress parameters in stepwise multivariable linear regression analysis. CONCLUSION This study suggests that levothyroxine replacement decreases oxidant status and increases antioxidant status following the 6 months of levothyroxine replacement in hypothyroidism that develops in accordance with the HT.

Impact of specimen adequacy on the assessment of renal allograft biopsy specimens. ACTA ACUST UNITED AC 2016; 49:e5301.

Abstract
The Banff classification was introduced to achieve uniformity in the assessment of renal allograft biopsies. The primary aim of this study was to evaluate the impact of specimen adequacy on the Banff classification. All renal allograft biopsies obtained between July 2010 and June 2012 for suspicion of acute rejection were included. Pre-biopsy clinical data on suspected diagnosis and time from renal transplantation were provided to a nephropathologist who was blinded to the original pathological report. Second pathological readings were compared with the original to assess agreement stratified by specimen adequacy. Cohen's kappa test and Fisher's exact test were used for statistical analyses. Forty-nine specimens were reviewed. Among these specimens, 81.6% were classified as adequate, 6.12% as minimal, and 12.24% as unsatisfactory. The agreement analysis among the first and second readings revealed a kappa value of 0.97. Full agreement between readings was found in 75% of the adequate specimens, 66.7 and 50% for minimal and unsatisfactory specimens, respectively. There was no agreement between readings in 5% of the adequate specimens and 16.7% of the unsatisfactory specimens. For the entire sample full agreement was found in 71.4%, partial agreement in 20.4% and no agreement in 8.2% of the specimens. Statistical analysis using Fisher's exact test yielded a P value above 0.25 showing that - probably due to small sample size - the results were not statistically significant. Specimen adequacy may be a determinant of a diagnostic agreement in renal allograft specimen assessment. While additional studies including larger case numbers are required to further delineate the impact of specimen adequacy on the reliability of histopathological assessments, specimen quality must be considered during clinical decision making while dealing with biopsy reports based on minimal or unsatisfactory specimens.

Abstract
INTRODUCTION We evaluated that response to parenteral iron therapy could be helpful in distinguishing the types of iron deficiency anemia. PATIENTS AND METHODS This study analyzed responses to IV iron sucrose therapy of 15 children with unexplained refractory iron deficiency anemia (URIDA). We compared the results at diagnosis, 6 weeks and 6 months after the therapy. Results were compared with responses of 11 patients' results with iron-refractory iron deficiency anemia (IRIDA) from our previous study. RESULT Six weeks after the start of treatment, ferritin, MCV, MCH and Hb values were in normal range in 10 patients. The increase in Hb, MCH, MCV, and ferritin values ranged 2.6-3.5 g/dL, 1.7-4.2 pg, 2-9 fL, and 13-25 ng/mL, respectively. In five patients, Hb, MCH, and MCV mean (range) values [11.2 g/dL (11-12.2), 24.5 pg (24-25.6), and 67 fL (65-70)] were nearly normal but ferritin mean (range) values [9.8 ng/mL (8-11)] were below normal. Six weeks after the start of treatment, Hb, MCH, MCV and ferritin values of patients with IRIDA were increased. The increase in Hb, MCH, MCV, and ferritin values ranged 0.8-2.7 g/dL, 1.7-4.2 pg, 2-9 fL, and 13-25 ng/mL, respectively. IRIDA is only partially responsive to parenteral iron supplementation. In conclusion, this study demonstrated that the response to intravenous iron therapy for the URIDA cases improved blood parameters more effectively than hereditary IRIDA. Response to parenteral iron therapy would be helpful to distinguish unexplained refractory IDA from hereditary IRIDA for clinicians who do not have access to hepcidin or TMPRS6 mutation analysis.

Abstract
In this study, we aimed to examine dynamic thiol/disulfide homeostasis in type 1 diabetes mellitus (T1DM) and identify the factors associated with thiol oxidation. Thirty-eight subjects (18 male, 20 female) diagnosed with T1DM and 38 (17 male, 21 female) healthy volunteers without any known diseases were included in the study. Thiol/disulfide homeostasis concentrations were measured by a newly developed method (Erel & Neselioglu) in this study. After native thiol, total thiol and disulfide levels were determined; measures such as disulfide/native thiol, disulfide/total thiol, and native thiol/total thiol were calculated. In T1DM patients, compared to the control group, disulfide (p = 0.024), disulfide/native thiol (p < 0.001), and disulfide/total thiol (p < 0.001) were determined higher, while native thiol (p = 0.004) and total thiol (p < 0.001) levels were much lower. In the patient group, a positive correlation was determined between c-reactive protein (r = 325, p = 0.007; r = 316, p = 0.010, respectively), fasting blood glucose (r = 279, p = 0.018; r = 251, p = 0.035, respectively), and glycosylated hemoglobin (r = 341, p = 0.004; r = 332, p = 0.005, respectively) and rates of disulfide/native thiol and disulfide/total thiol. We determined that thiol oxidation increase in T1DM patients compared to the control group. We thought that hyperglycemia and chronic inflammation might be the major cause of increase in oxide thiol form. In order to determine the relationship between the status of autoimmunity and dynamic thiol/disulfide in T1DM, dynamic thiol/disulfide homeostasis in newly diagnosed-antibody positive-T1DM patients is required to be investigated.

Abstract
Sensorineural hearing loss has been reported in various autoimmune diseases. The relationship between Hashimoto's thyroiditis (HT) and the auditory system has not been previously evaluated. In this study, we investigated the effect of euthyroid HT on the hearing ability of adult patients. The study included 30 patients with newly diagnosed euthyroid HT and 30 age- and gender-matched healthy controls. All subjects had a normal otoscopic examination and tympanometry, and they were negative for rheumatoid factor, antinuclear, anti-smooth muscle, antimitochondrial, antineutrophilcytoplasmic, and antigliadin antibodies. Pure tone audiometry exams at 250, 500, 1000, 2000, 4000, 6000, and 8000 Hertz (Hz) were performed in both groups. Thyroid peroxidase antibody and thyroglobulin antibody (anti-Tg) levels were higher in HT group while TSH, free T4, free T3, plasma electrolytes, glucose, lipid profile, vitamin B12, and blood pressure measurements were similar between the two groups. Higher audiometric thresholds and a higher prevalence of hearing loss at 250, 500, and 6000 Hz were detected in the HT patients than in the healthy controls (P < 0.05). Hearing levels at 250 and 500 Hz correlated positively with anti-Tg levels (ρ = 0.650, P = 0.002; ρ = 0.719, P < 0.001, respectively), and this association remained significant in linear regression analysis. Anti-Tg-positive HT patients had higher hearing thresholds at 250 and 500 Hz than anti-Tg-negative HT patients. Hearing thresholds were similar between anti-Tg-negative HT patients and the control subjects. This study demonstrated that hearing functions are impaired in HT patients. Thyroid autoimmunity seems to have an important impact on a decreased hearing ability, particularly at lower frequencies, in this population of patients.

Abstract
AIMS Our aim was to examine thiol/disulfide homeostasis, which has a critical role in many cellular activities such as antioxidant protection, detoxification, cell growth and apoptosis, in prediabetic patients. METHODS The study population was formed of a total of 250 participants; 125 (54 males, 71 females) of which were newly diagnosed with prediabetes, aged over 18 and who had not received any prior treatment and 125 (52 males, 73 females) healthy volunteers. Prediabetic patients were diagnosed using a glucose tolerance test. In both groups, native thiol-disulfide exchanges were examined using the automated measurement method newly developed by Erel and Neselioglu. RESULTS When compared to the control group, the native thiol (p<0.001) and total thiol (p=0.008) levels, and the native thiol/total thiol (p=0.022) ratio was lower; while disulfide (p=0.001) level and, disulfide/native thiol (p=0.003) and disulfide/total thiol (p=0.022) ratios were higher in prediabetic patients. A positive correlation was determined between disulfide and the fasting blood glucose levels (r=0.394, p=0.017) and glycolysed hemoglobin (HbA1c) (r=0.307, p=0.011). On the other hand, a negative correlation was determined between native thiol and fasting blood glucose levels (r=-0.335, p=0.004). CONCLUSION With this study, we have shown for the first time that thiol oxidation increases in prediabetic patients and that there is a positive correlation between the disulfide and blood glucose and HbA1c levels.

Abstract
BACKGROUND Subclinical hypothyroidism (SH) occurs when serum thyroid stimulating hormone (TSH) concentrations are raised and serum thyroid hormone concentrations are normal. The effect of SH on the proinflammatory adipose cytokine releasing visceral adipose tissue (VAT) is not clear. The aim of this study is to identify the difference between the pre and posttreatment levels of VAT, leptin, and resistin in SH patients. METHODS There were 51 SH patients and 43 age- and gender-matched healthy subjects included in the study. Thyroid functions, biochemical tests, leptin, resistin, and visceral and subcutaneous fat measurements were made. The measurements were repeated in the SH group in the third month following L-thyroxin treatment. RESULTS Initially, high sensitivity C-reactive protein, carotid artery intima-media thickness (mm), leptin, and resistin levels were significantly higher in the SH group compared to the controls, while the other parameters were similar. While no correlation was observed between TSH levels and adipokines, a positive correlation was detected between waist circumference and leptin levels (r = 0.549, p < 0.01). Visceral adipose tissue was positively correlated to age, waist circumference, and leptin levels, but negatively correlated to free thyroxin (T4) levels (r = 0.419, p = 0.009; r = 0.794, p < 0.01; r = 0.515, p < 0.01 and r = - 0.416, p = 0.009, respectively). A significant decrease was observed in VAT volume, leptin, and resistin levels of SH patients following levothyroxine treatment. Conclusion The reduced VAT volume, leptin, and resistin levels in SH patients following treatment may support the idea that TSH affects adipose tissue functions.

Higher body mass index and larger waist circumference may be predictors of thyroid carcinoma in patients with Hürthle-cell lesion/neoplasm fine-needle aspiration diagnosis. Clin Endocrinol (Oxf) 2015; 83:405-11. [PMID: 25296952 DOI: 10.1111/cen.12628] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/22/2014] [Revised: 09/10/2014] [Accepted: 10/02/2014] [Indexed: 12/26/2022]
Abstract
OBJECTIVE High body mass index (BMI) has been found to be associated with raised thyroid cancer risk, particularly in women. We examined the associations for BMI and waist circumference (WC) with thyroid cancer risk among women with Hürthle-cell lesion/neoplasm (HLN) on fine-needle aspiration biopsy (FNAB) with the hypothesis that BMI and WC could guide the management of these challenging indeterminate lesions. METHODS This cross-sectional study included 224 women with HLN who underwent thyroidectomy. In all patients, TSH and thyroid auto-antibodies were evaluated, and thyroid nodule features were recorded. Patients were grouped according to BMI (<30 or ≥30 kg/m(2)) and WC (<88 or ≥88 cm). Relationships of thyroid cancer with BMI and WC were assessed using logistic regression analysis. RESULTS Mean weight, BMI (31·26 ± 5·1 vs 26·47 ± 5·9, P < 0·001), WC (98·23 ± 7·6 vs 86·18 ± 11, P = 0·001), and proportion of patients with high BMI (≥30 kg/m(2)) (65·9 vs 33·8%, P < 0·001) or large WC (≥88 cm) (84·1 vs 47·9%, P < 0·001) were significantly higher in malignant group compared to benign group. In regression analysis, BMI and WC significantly associated with existence of malignancy. Malignancy risk was 3·819-fold higher (95% CI: 2·068-7·054) in BMI≥30 kg/m(2) group compared to BMI<30 kg/m(2), which was independent of TSH and age. Large WC was also associated with increased risk (OR = 5·593, 95% CI: 2·736-11·434). Baseline tumour characteristics were similar according to BMI and WC groups. CONCLUSIONS A great BMI and large WC were associated with higher thyroid cancer risk in patients with FNAB diagnosis of HLN. Further studies are needed to use BMI or WC in the management of patients with HLN.

Type 2 diabetes affects sleep quality by disrupting the respiratory function. J Diabetes 2015; 7:664-71. [PMID: 25266369 DOI: 10.1111/1753-0407.12225] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/29/2014] [Revised: 09/11/2014] [Accepted: 09/21/2014] [Indexed: 11/30/2022] Open
Abstract
BACKGROUND The effects of diabetes on the respiratory system were investigated with arterial blood gas, sleep quality index and respiratory functions tests. METHODS Fifty-three patients with type II diabetes and 41 healthy cases were included. Their biochemical data, demographic characteristics, anthropometric measurements and echocardiographic findings were collected from polyclinic records. Respiratory function tests were performed for all subjects and Pittsburgh Sleep Quality Index questionnaire was conducted. Aforementioned data were compared between these two groups. RESULTS The age, body weight and body mass index were similar but oxygen pressure, oxygen saturation, forced vital capacity (FVC; %), and sleep quality were decreased in patients with diabetes. Sleep quality was correlated with the presence of diabetes and hypertension, duration of diabetes, fasting and postprandial blood glucose levels, homeostasis model of assessment-insulin resistance, Glycosylated hemoglobin levels, and FVC. Half of the diabetic patients exhibited respiratory failure during sleep. Especially diabetic patients with autonomic neuropathy, experienced a more severe and prolonged decrease in oxygen saturation. CONCLUSIONS Blood gas, respiratory functions and sleep quality, which need to be evaluated as a whole, were affected in patients with diabetes. Assessment of sleep and its quality requires special attention in patients with diabetes.

Abstract
The role of insulin resistance (IR) is well-documented in obese women with polycystic ovary syndrome (PCOS). Controversies exist concerning the presence of IR in idiopathic hirsutism (IH) or if it is a manifestation of high body mass index (BMI). We aimed to investigate the presence/absence of IR in lean hirsute women. One-hundred fifty-one lean women with hirsutism [96 PCOS (group 1) and 55 IH (group 2)] and 58 age-and BMI-matched healthy controls (group 3) were recruited in the study (mean age 25.21 ± 6.1 versus 26.26 ± 4.6years; BMI 21.79 ± 1.7 versus 22.02 ± 2.2 kg/m(2), respectively). Significantly higher insulin and HOMA-IR, and significantly lower fasting glucose insulin ratio (FGIR), quantitative insulin sensitivity check index (QUICKI), reciprocal insulin, and Raynaud index were detected in groups 1 and 2 than in group 3 (p < 0.05). These IR indices were similar between groups 1 and 2. The number of patients with IR (HOMA-IR > 2, FGIR < 7.2, or QUICKI < 0.357) was significantly higher in groups 1 and 2 than in group 3, but was similar between groups 1 and 2. A higher frequency of IR occurs in lean hirsute women regardless of they having PCOS or IH. IR may contribute to aetiopathogenesis of IH, or may cause some metabolic abnormalities in these patients.

Retrospective comparison of cabergoline and bromocriptine effects in hyperprolactinemia: a single center experience. J Endocrinol Invest 2015; 38:447-53. [PMID: 25421155 DOI: 10.1007/s40618-014-0212-4] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/26/2014] [Accepted: 11/12/2014] [Indexed: 10/24/2022]
Abstract
INTRODUCTION Patients with hyperprolactinemia who require medical therapy are typically treated with dopamine agonists (DAs). In most cases, DAs normalize prolactin levels, control symptoms, and substantially decrease tumor size. Here, we aimed to compare the efficacy of cabergoline (CAB) and bromocriptine (BRC) in patients with hyperprolactinemia at a single center. METHODS Retrospective analysis of the clinical records of 498 patients with hyperprolactinemia [mean age 33.3 ± 10.8 years (range 16-66), 450 women, and 48 men] who had received either CAB (n = 450) or BRC (n = 48) was performed. RESULTS The mean age, gender distribution, and treatment duration were similar between the CAB and BRC groups (33.2 ± 11 vs. 34.1 ± 9.6 years, male/female 44/406 vs. 4/44, 18.7 ± 12.1 vs. 17.8 ± 6.0 months, respectively; p > 0.05 for all). Mean dosage was 1.5 ± 1.6 mg/week for CAB and 3.8 ± 2.7 mg/day for BRC. Baseline prolactin levels, frequency of galactorrhea, amenorrhea, oligomenorrhea, erectile dysfunction, infertility, and visual impairment were similar between the two groups, whereas the baseline tumor volume was higher in the CAB group. The prolactin normalization rate (87.4 vs. 41.4 %, p = 0.029) and tumor volume shrinkage (79.8 ± 39.1 vs. 54.1 ± 55.3 %, p = 0.015) were significantly higher in the CAB-treated patients than in the BRC-treated patients, while the tumor cure rates were similar. Symptom relief was higher in the CAB group than in the BRC group. More side effects were recorded in patients who took BRC (29.1 vs. 5.3 %, p < 0.001). CONCLUSION Our data revealed that CAB was more effective than BRC in controlling symptoms associated with hormone excess, normalizing serum prolactin levels, and shrinking prolactinomas.
