Abstract Background: Differences in far interpupillary distance (IPD) in Turkish and Azerbaijani adults of the same ethnic background from different age groups were examined to investigate the effects of ethnicity, genetics, geography, and environmental factors on IPD. Methods: A total of 1,400 healthy individuals aged ≥18 years were enrolled. The far IPD of each individual was determined in both communities. IPD data for 700 subjects in Azerbaijan and 700 subjects in Turkey was analyzed. Males and females were divided into six age ranges: 18–24, 25–34, 35–44, 45–54, 55–64, and ≥65 years. Far IPD data in Turkey and Azerbaijan was collected using two types of autorefractometers: Topcon RM 8800 and Topcon TRK-2P.Results: The mean age of the 700 subjects in Turkey was 44.5 ± 17.6 years. The mean IPD was 62.1 ± 3.7 mm. The mean IPD in females was 61 mm, which was less than males (63 mm) (P < 0.05). The mean age of the 700 Azerbaijani subjects was 44.0 ± 15.6 years. The mean IPD of the subjects was 65.0 ± 3.1 mm. The mean IPD (64 mm) in females was significantly lower than the mean IPD (66 mm) in males (P < 0.05). Differences in IPD between age groups in both communities were statistically significant (P < 0.05). The mean IPD in all age groups in the Azerbaijani population was greater than that of the Turkish population. Compared with other ethnic groups, the mean IPD in the Azerbaijani population was remarkably high.Conclusions: When mean far IPD values in individuals aged ≥18 years in the Azerbaijani and Turkish populations were compared, statistically significant differences were observed. In Azerbaijani Turks, mean IPD values in both males and females were greater than those observed in the Turkish population in all age groups. The mean IPD values of the Azerbaijani population were greater than those of other ethnic groups when classified by both age and sex. As well as ethnicity, geographical and environmental factors influenced far IPD values.

Purpose To establish normal exophthalmometry values in the adult Turkish population, and the impact of age, gender, interpupillary distance, Hertel base selection, and refractive status on globe position. Methods Exophthalmometry measurements and refractive status of 2477 subjects were conducted in one tertiary and five primary health care centers. Change of globe position by age, intersex differences in terms of globe position, correlations of Hertel base with exophthalmometry results, and interpupillary distance (IPD) were evaluated. Multiple linear regression analysis was performed to test determination effect of each variable on final Hertel reading. Results Median Hertel reading was 13 mm, and 95% of the population had an upper limit of 17 mm for both eyes. There was a negative correlation between spherical equivalent of refractive status and exophthalmometry results and a weak positive correlation between IPD and exophthalmometry result. Mean Hertel value was found to decrease significantly after the third decade. Hertel base value was found to have moderate linear correlation with Hertel results. A weak correlation was detected with Hertel base/IPD ratio with final Hertel results. Multiple linear regression analysis was performed and only 13% and 20% of change in Hertel values bilaterally were found to be determined by other variables (age, IPD, refractive status, and Hertel base value) for females and males. Conclusions Normative dataset for exophthalmometry results of the Turkish population is established to be used in clinical practice and research. Only 13% to 20% of change in Hertel values was detected to be determined by age, IPD and Hertel base values.

Türkiye'de 20.yy'ın ortasından itibaren başlayan iç göçler zamanla kurulan göçmen ağları ile süreklilik kazanmış ve ülke içinde nüfusun kır-kent dağılımını değiştirecek boyutlara erişmiştir. Araştırma, göçün doğum yeri verisinden hareketle ikamet edilen yerdeki nüfus miktarına göre alınan ve verilen göç akışının büyüklüğünü iller ölçeğinde yönlü ağlar kullanılarak analiz edilmesini amaçlamaktadır. Araştırmada, TÜİK tarafından yayınlanmış olan 2015 yılına ait, iller ölçeğinde doğum yerine göre ikamet yeri verisi kullanılmıştır. Göçün kaynak ve hedef sahaları arasındaki akışını incelemek için NodeXL ile oluşturulan tek modlu, yönlü ve ağırlıklandırılmış göç ağının istatistiksel olarak tam ağ yapısına sahip olduğu görülmüştür. Ağ grafiklerinden ve istatistiklerinden göç hareketinin doğudan batıya doğru gerçekleştiği ve İstanbul’ un ülkenin tamamına hâkim bir görünüme sahip olduğu anlaşılmaktadır. Türkiye nüfusunun cumhuriyet tarihi içinde geçirdiği iç göç süreçleriyle birlikte ülke içinde kurulmuş ve oldukça karmaşık bir görünüme sahip ağ yapısının olduğu ileri sürülebilir. Kurulan ağlar göçlerin devamını sağladığı gibi, göçün yöneldiği merkezlerde daha heterojen nüfus yapılarının ortaya çıkmasına yol açmıştır.ABSTRACT IN ENGLISHSocial Network Analysis of Migration Inter Provinces In Turkey with Nodexl The internal migrations which started in Turkey in the middle of the 20th century have gained permanency with the migration networks that were established at the time and reached dimensions which have the potential to change the rural-urban distribution of the population within the country.  The study aims to analyze the magnitude of the incoming and outgoing migration flow at the provincial scale based on the population data for place of birth according to place of residence by using directional networks. Place of residence according to place of birth at the provincial scale data for 2015 published by TÜİK was used in the study. A single mode, directional and weighted migration network created with NodeXL to examine the migration flows between the source and target has a statistically complete network structure. The network graphs and statistics show that the migrations have taken place from east to west and Istanbul has a view as dominant of the country. It can be argued that internal network structure of Turkish population has  a very complex view because of internal migration in the history of the republic. The established networks have enabled the continuation of migration and have manifested as the emergence of more heterogeneous population structures in centers where migration had been directed.

<b><i>Background:</i></b> Psoriasis known as a chronic inflammatory skin disease is accompanied by metabolic disorders such as obesity, diabetes, and dyslipidemia. Vaspin (a serine protease inhibitor derived from visceral adipose tissue) is a newly identified adipokine and a link between inflammation and obesity has been reported. We aimed to determine whether vaspin gene polymorphism is associated with the development and/or clinical features of psoriasis vulgaris. <b><i>Methods:</i></b> Our study group consisted of 96 psoriasis vulgaris patients and 100 matched controls. Vaspin rs2236242 gene was genotyped using PCR. <b><i>Results:</i></b> The vaspin genotypes showed a meaningful difference between psoriasis and control groups (<i>p</i> = 0.02). The frequency of the vaspin rs2236242 TT genotype was lower in psoriasis patients than in control participants (<i>p</i> &#x3c; 0.05). The TA genotype was associated with a 2.38-fold increased risk of psoriasis compared to the TT genotype (<i>p</i> = 0.007, odds ratio: 2.38; 95% confidence interval: 1.25–4.55), but not the AA genotype. All subjects were the Turkish population, the study in other populations is needed and the sample size was small in number. <b><i>Conclusion:</i></b> Our study demonstrated that vaspin rs2236242 polymorphism is related to psoriasis in the Turkish population. Polymorphisms of the vaspin gene might serve as diagnostic biomarkers of psoriasis.

AbstractSince forensic age estimation is not a valid medical indication, research on the use of nonionizing methods is increasing. Ultrasonography is a radiological approach that protects patients from radiation exposure and offers special convenience to them. In this study, ultrasonography was used for age estimation by investigating the degree of ossification of the distal radial epiphysis. Its applicability on the Turkish population was investigated. The left wrist of 688 (322 males, 366 females) patients between the ages of 9 and 25 years was prospectively evaluated by ultrasonography. The intra- and interobserver reliabilities in evaluating the distal radial epiphysis and Cohen’s kappa statistics show that the interobserver error was very low, and the kappa value was found to be 0.919. Stage 3 and 4 ossification of the distal radial epiphysis was first detected at age 14.3 and 15.3 years in males and 12.7 and 14.8 years in females, respectively. The data obtained may help determine legally critical age limits of 14 and 15. Although it does not seem useful for the age of 18, ultrasonography may be recommended in selected cases as a fast, inexpensive, frequently reproducible radiological method without concern about radiation and without a predictable health risk.
