Article Citation - Scopus: 1Serum Clusterin Levels Are Not Associated With Chronic Spontaneous Urticaria Regardless of Serum Lipids(Edizioni Minerva Medica, 2022) Vurgun,E.; Memet,B.; Etikan,P.; Guntas,G.; Kocaturk,E.BACKGROUND: Clusterin is related to immunity and inflammation via regulation of complement activation and bidirectional regulation, and by major proinflammatory cytokines. Clusterin levels have been the subject of a few research both in patients with hyperlipidemia and those with chronic spontaneous urticaria (CSU) separately. The aims of this study were to evaluate the levels of clusterin levels and serum lipids and the relationships between them in patients with CSU. METHODS: Fifty patients with CSU and 30 healthy controls were enrolled into the study. The activity of urticaria of the patients was determined by urticaria activity score (UAS7). Serum clusterin, total cholesterol, HDL, LDL and triglyceride levels of the participants were measured and compared. The relationships between UAS, lipids and clusterin were examined. RESULTS: There was no difference in clusterin levels between CSU patients and controls. Clusterin level was not related to activity of urticaria. Clusterin levels were not correlated with any of lipid parameters neither in CSU patients nor in controls. CONCLUSIONS: Findings of this study show that clusterin levels do not change due to CSU. Serum clusterin levels cannot be used as a diagnostic or a disease activity marker in CSU patients, regardless of the lipid profile. © 2022 EDIZIONI MINERVA MEDICA.Article Citation - WoS: 6Citation - Scopus: 5Prognostic Value of Metabolic Parameters on Baseline 18f-Fdg Pet/Ct in Small Cell Lung Cancer(Edizioni Minerva Medica, 2022) Araz, Mine; Soydal, Cigdem; Ozkan, Elgin; Sen, Elif; Nak, Demet; Kucuk, Ozlem N.; Kir, K. MetinBACKGROUND: Maximum standardized uptake value (SUVmax) is the primary quantitave parameter given in 18F-FDG PET/CT reports. Calculations derived from three dimensional metabolic volumetric images have been proposed to be more successful than SUVmax alone in prognostification with a lower interobserver variability in many cancers. We aimed to determine the prognostic value of metabolic parameters derived from 18F-FDG PET/CT studies in small cell lung cancer (SCLC) patient population with a long follow-up time. METHODS: In this study, 38 consecutive SCLC patients (34M, 4F, age:65.76 +/- 8.18 years) who were referred to 18F-FDG PET/CT for staging between October 2006-January 2011 were included. SUVmax, SUVmean, SUVpeak, metabolic tumor volume (MTV), and total lesion glycolysis (TLG) were calculated. Overall survival (OS) was calculated from the date of the initial PET/CT to death from any cause. Survival tables were obtained and Kaplan Meier curves were reconstructed. Mantel-Cox regression analysis was performed in order to investigate if any of these parameters have an effect on survival along with other clinical risk factors. RESULTS: Median SUVmax, SUVmean, SUVpeak, MTV, TLG and LDH values were calculated as 13.9 g/dL, 6.4 g/dL,10.69 g/dL, 147 cm(3), 1898.52 and 375U/L respectively. Median follow-up was 761.23 +/- 873.21 days (25.37 months, range:110-3338 days). Since basal 18F-FDG PET/CT scans, all patients were lost in the follow-up except for two patients. MTV was a significant prognostic factor in SCLC patients. Estimated mean survival times were 261.0 +/- 45.6 (95% CI: 171.6-350.3) days in patients with MTV value above the calculated median 147, and 577.0 +/- 124.0 (95% CI: 333.7-820.2) days in patients with MTV<147. The difference was statistically significant with a P=0.037. CONCLUSIONS: Baseline whole body MTV reflecting total tumor load is a prognostic index in SCLC. SUV is insufficient to predict prognosis.Article Citation - WoS: 2Citation - Scopus: 2Effect of Mesenchymal Stem Cells Therapy in Experimental Kaolin Induced Syringomyelia Model(Edizioni Minerva Medica, 2022) Bal, Ercan; Hanalioglu, Sahin; Kopru, Cagla Z.; Kose, Sevil; Basak, Ahmet T.; Pehlivan, Sibel B.; Bozkurt, GokhanBACKGROUND: Syringomyelia is a pathological cavitation of the spinal cord. In this study, we examined whether a syrinx cavity would limit itself with axonal regeneration and stem cell activity in the cavity, and we evaluated subjects on a functional basis. METHODS: Groups were designated as kaolin, trauma, kaolin-trauma, and saline groups. Also divided out of the syringomyelia treated groups were those given human mesenchymal stem cells (hMSCs). All groups were evaluated with immunohistochemistry, electron microscopy, confocal microscopy and functionally. RESULTS: The kaolin-trauma group had a significant correction of BBB score with hMSCs therapy. The syrinx cavity measurements showed significant improvement in groups treated with hMSCs. The tissue surrounding the syrinx cavity, however, appeared to be better organized in groups treated with hMSCs. The process of repair and regeneration of damaged axons in the lesion were more improved in groups treated with hMSCs. Using confocal microscopy, fluorescence of hMSCs was observed in the central canal, in the ependymal tissue, and around the lesion. CONCLUSIONS: It was concluded that axonal repair accelerated in groups receiving stem cells, and thus, stem cells may be effective in recovery of neural tissue and myelin damage in syringomyelia.Article Citation - WoS: 3Citation - Scopus: 3Assessments of World and National Level Wrestling Teams at a Pre World Championship Competition: Hydration, Body Composition and Body Mass Alterations(Edizioni Minerva Medica, 2015) Kutlu, M.; Demirkan, E.; Ozbek, M. E.; Department of Electrical & Electronics EngineeringAim. This study examined the changes in hydration status, body composition and body mass alterations during the camping period a pre world championship, World (N.=14) and National (N.=38) senior wrestlers (N.=52) preparing for the World Championships. Methods. Urine specific gravity, conductivity and color measurements with, body composition analyses were conducted at the beginning of the camp and the end of the camp. Results. In general, no significant differences were obtained between the world and national wrestlers in body mass and fat percentage (83.3 +/- 20-84.9 +/- 18 kg; 12 +/- 6%-11.2 +/- 4%, respectively). However, a significant difference was detected in the changes of body mass between groups (world decreased [800 +/- 1 g] - national increased [600 +/- 1 g] [P<0.05]). Body fat percentage was also observed to have a similar bias with a decrease and increase, but the changes were not significantly different (P>0.05). No significant differences (P>0.05) were observed between pre- and post-test values of urine specific gravity, conductivity or color for both national team wrestlers. Conclusion. Wrestlers achieved to adjust to weight category in a close of period through competition weigh in. Dehydration training programs should be sustained during the whole camp seasons including the last days before the weighing process for matches.
