Item Careers and Research Performance of PhD Program Graduates of Health Sciences in TurkeyCavdar, Z; Ulman, C; Kirkali, G; Baydur, H; Akdogan, GGIn this review, we aimed to evaluate PhD graduates of the period between 1985-2010 and analyze the status, motivation and positive and negative factors influencing research motivation of graduates in eight disciplines from three graduate schools of Health Sciences in Turkey and to compare with the present status in the world. Some information obtained by web-based survey is the following: The most of graduates (83%) have academic positions in basic sciences departments in the faculty of medicine in universities. 94.2 % of graduates recognized the importance of personal motivation, while 54% of them thought that finding the appropriate research environment was important for research. For 52%, the biggest hindrance to medical research was lack of funding and for 39%, lack of technic personnel for research. The studies in the literature related to PhD graduates pointed out to the following facts: The number of PhD graduates is increasing gradually and the graduates' career choices have changed from academic to non-academic positions, especially in the industry. This is not parallel to our pilot study findings. About the teaching perspective treated in the relevant literature, the concept of one should be a good researcher, as well as a good teacher is dominant. PhD graduates in our pilot study mentioned that they had responsibilities in the education activities during their PhD education. We think that these responsibilities are useful for their future academic career. In conclusion, the majority (83%) of graduates from Graduate Schools of Health Sciences in Turkey are enrolled into academic researcher positions in universities. They keep producing funded research work as a first author and publish despite some problems.Item Plasma selenium and urinary iodine in patients with goiterHekimsoy, Z; Biberoglu, S; Kirkali, G; Bicer, N; Erbayraktar, ZObjective: Iodine deficiency and related disorders are still major public health problems, with a high prevalence of endemic goiter in many regions of Turkey. In addition to measuring iodine excretion rates in patients with diffuse or nodular goiter, we examined plasma selenium concentrations, to see whether selenium deficiency might be related to goiterogenesis in our region. Methods: Seventy-two outpatients with goiter (67 female, 5 male; age 43.7 +/- 13.0 years) presenting consecutively to our university medical center endocrinology clinic, were included in the study group. The control group consisted of 30 subjects (25 female, 5 male; age 40.6 +/- 13.6 years) who were healthy and did not have any known thyroid disease. None of the subjects were using medications containing selenium or iodine. Serum thyroid hormones, plasma selenium and urinary iodine levels were measured, and an ultrasound of the thyroid was performed in both groups. Results: Serum thyroid hormone levels were in the normal range in both groups and the difference was not significant. Mean plasma selenium levels in the study and control groups were not significantly different (p = 0.30). However, urinary iodine excretion was significantly lower in the study group (17.4 +/- 12.6 mug/l vs 23.2 +/- 12.2 mug/l, p = 0.03). In both study and control group patients, a significant negative correlation between thyroid volume and urinary iodine levels was observed. Conclusion: Moderate to severe iodine deficiency is the primary etiologic factor for endemic goiter in our region. Plasma selenium levels were not related to the presence or absence of goiter in our population.Item Careers and research performance of PhD Program Graduates of Health Sciences in TurkeyCavdar, Z; Ulman, C; Kirkali, G; Baydur, H; Akdogan, GG
