New Genera Anatolidamnicola and Sivasi (Gastropoda: Hydrobiidae) from Sivas and Malatya (Turkey)

New freshwater genera (Anadoludamnicola and Sivasi) of Hydrobiidae are described for new hydrobiid species (Anadoludamnicola gloeri and Sivasi bodoni) from material collected from provinces Sivas and Malatya (Turkey), using anatomical and morphological data. For now, Sivasi is known from a single locality, while we expect Anadoludamnicola will be found to be commonly distributed in Anatolia

The impact of hypertension on retinal nerve fiber layer thickness and its association with carotid intima media thickness

WOS: 000354191800007PubMed: 25658169Objective. Our aim was to investigate retinal nerve fi ber layer (RNFL) thickness in hypertensive patients using spectraldomain optical coherence tomography (SD-OCT) and to evaluate the relationship between RNFL thickness and carotid intima media thickness (CIMT). Methods. This study included 59 patients with hypertension (HT) (53.6 +/- 10.7 years) and 54 age-matched healthy controls (51.0 +/- 8.1 years). We evaluated anthropometric and metabolic parameters as well as RNFL and CIMT measurements in patients with hypertension and controls. Results. the average RNFL thickness was 86.60 +/- 10.86 mu m in hypertensive patients and 93.63 +/- 7.30 mu m in healthy controls (p < 0.001). Selective thinning of the RNFL was found in the superior and inferior quadrants. Mean CIMT values were higher in patients with HT (0.80 +/- 0.15 mm) than the healthy subjects (0.71 +/- 0.1 mm) (p < 0.001). the average, inferior and nasal RNFL thickness were negatively associated with diastolic blood pressure respectively (r= 0.112, r= 0.210, r= 0.225). There was an inverse correlation between RNFL thickness in the average and superior retinal quadrant and CIMT (r- =0.201, r= -0.185). There were no correlations between RNFL thickness and age, body mass index, fasting plasma glucose, lipid parameters, high-sensitive C-reactive protein and microalbuminuria. Conclusion. RNFL thickness is reduced in hypertensive patients and may be associated with atherosclerosis

Fibroblast growth factor 21 and its relation to metabolic parameters in women with polycystic ovary syndrome

Cure, Medine Cumhur/0000-0001-9253-6459WOS: 000342056100001PubMed: 24724557Objective. the aim of this study was to compare the serum levels of fibroblast growth factor 21 (FGF-21) between patients with polycystic ovary syndrome (PCOS) and control subjects and to assess the possible relation with the hormonal and metabolic parameters. Methods. A total of 91 patients with PCOS and 53 age- and body mass index (BMI)-matched healthy controls were included in the study. We evaluated anthropometric, hormonal and metabolic parameters in all the cases. Serum FGF-21 and high sensitive C-reactive protein (hsCRP) levels were measured by ELISA. Results. Mean fasting glucose and insulin, homeostasis model assessment insulin resistance index (HOMA-IR), triglyceride, total cholesterol, low density lipoprotein cholesterol, total testosterone, dehydroepiandrosterone sulfate (DHEAS) levels were significantly higher in PCOS patients. Serum FGF-21 levels were similar in PCOS (236.8 +/- 171.2 pg/ml) and the control (224.6 +/- 128.9 pg/ml) group (p = 0.654). FGF-21 level had no correlation with BMI, waist circumference, HOMA-IR, hsCRP and lipid parameters. However there was a significant negative correlation between FGF-21 and DHEAS levels (r = -0.309, p = 0.003). Conclusion. FGF-21 levels were similar in women with PCOS compared with those of age- and BMI-matched controls

Alterations of thyroid volume and nodular size during and after pregnancy in a severe iodine-deficient area

WOS: 000344176900017PubMed: 24811142ObjectiveThe effects of pregnancy on thyroid nodules were investigated in a few number of studies. We aimed to evaluate the prevalence of thyroid nodules, the changes in size, volume and number of nodules during pregnancy and after delivery in pregnant women. Design and methodsThis prospective study was performed in a severe iodine-deficient area and included 83 pregnant women (mean age 30455years). We evaluated thyroid hormone levels, ultrasound examination of thyroid and urine iodine concentration (UIE) at each trimester and at 3-month post-partum period (PP). All patients with thyroid nodules >1cm underwent fine-needle aspiration biopsy (FNAB) after the last visit at the PP. ResultsTwenty-six women had thyroid nodules on thyroid ultrasonography at the first trimester. the volume of single/dominant nodule showed enlargement during pregnancy and remained at the PP; however, it was not significant (first trimester: 083 +/- 08ml; second trimester: 092 +/- 1ml; third trimester: 099 +/- 12ml; PP: 092 +/- 12ml). the maximum diameter of single/dominant nodule in the third trimester of pregnancy (126 +/- 54mm) was greater than the first trimester (119 +/- 48mm) (P=0002). the number of nodules did not change during pregnancy. the mean TV increased during pregnancy and remained 3months after delivery (P<0001), and the maximum value of TV was reached in the third trimester (142 +/- 79ml). FNAB results revealed a 66% prevalence of malignancy among the nodules. ConclusionsThyroid nodules were present in 301% of pregnant women. While size of the single/dominant thyroid nodule increased significantly during pregnancy, the number of nodules did not change
