Item Initial neutrophil-to-lymphocyte ratio predicts radiation-induced trismus in parotid gland cancer(2023) Somay, Efsun; Yilmaz, Busra; Topkan, Erkan; Kucuk, Ahmet; Pehlivan, Berrin; Selek, Ugur; 0000-0001-8120-7123; 36349491; AAG-2213-2021ObjectiveTo investigate the link between pretreatment neutrophil-to-lymphocyte ratio(NLR) and the incidence of radiation-induced trismus(RIT) in parotid gland cancers(PGC) patients after postoperative radiotherapy(PORT). MethodData of PGC patients who had oral examinations before and after PORT were reviewed retrospectively. We comprised patients who had maximum mouth opening (MMO) assessments before and after PORT and complete blood count test on the first day of PORT. MMO of <= 35 mm was considered as RIT. The receiver operating characteristic (ROC) curve analysis was used to search for an ideal NLR threshold value that might be linked to RIT rates. ResultsFifty-one patients were included, with a RIT incidence of 15.7%. The NLR cutoff that showed a link with the prevalence of RIT in the ROC curve analysis was 2.7[Area under the curve (AUC):82.0%; sensitivity:87.5%; specificity:74.4%]. The patients were divided into groups based on this value:Group 1: NLR <= 2.7 (N = 34) and;NLR >2.7 (N = 17). In comparative analysis, the incidence of RIT was found to be statistically higher in the NLR >2.7 than counterpart (35.2%vs.5.8%;r(s):0.79; p < .001). Also, a mean temporomandibular joint dose >= 51.0Gy was linked to increased RIT rates (p < .001). ConclusionThis study showed that high pre-PORT NLR levels were a robust and independent predictor of significantly elevated rates of RIT.Item QTc interval is associated with increased inflammatory markers (neutrophil-to-lymphocyte ratio and LDH level) in COVID-19 patients(2021) Torun, Serife; Ozer, Nurtac; Celik, Olgun; Akcay, M. Sule; 0000-0002-7190-5443; AAD-5477-2021Purpose: This study aimed to investigate the association between QTc interval and laboratory parameters in COVID-19 patients before and after the treatment. Materials and Methods: Forty-three COVID-19 patients who had baseline and follow-up ECG findings and laboratory reports were evaluated and 40 patients were included in the study. Results: Among 40 patients, 16 were women and 24 were men. The neutrophil-to-lymphocyte ratio (NLR) and corrected QT (QTc) interval were significantly higher in females than males. After the treatment, a significant fall in CRP and ferritin values, and significantly prolonged QTc interval were seen. A significant positive correlation was observed between QTc interval and age, LDH levels, neutrophil and leukocyte count, NLR, magnesium levels, and heart rate of the patients prior to treatment. A positive correlation was observed between increased QTc interval and decreased LDH levels and NLR after treatment. Conclusion: QTc prolongation was associated with increased inflammatory markers, increased NLR and LDH levels before and after treatment in COVID-19 patients. The increase in the QTc interval was correlated with the reduction in LDH levels and NLR with treatment.Item Does methylene blue increases capsular contracture in immediate breast reconstruction with silicone implant? An experimental study(2020) Albayati, Abbas; Ozkan, Burak; Atilgan, Alev O.; Sencelikel, Tugce; Uysal, Cagri A.; Ertas, Nilgun M.; 0000-0003-2806-3006; 0000-0001-8595-8880; 0000-0001-6236-0050; 0000-0003-3093-8369; 33030384; AAC-3344-2021; AAK-3333-2021; AAJ-2949-2021Recently, most of the immediate breast reconstructions following mastectomy are being carried out with the use of silicone implants. In these patients, methylene blue is being used for the detection of sentinel lymph nodes. This experimental study was performed to determine the effect of methylene blue on capsular contracture around breast implants. Thirty-two Sprague Dawley rats were divided into 4 groups. Custom made silicone blocks were placed on the back of animals. In group 1, the incision was closed without performing any additional procedure. In group 2 (control), 0.1 mL of 0.9% normal saline was instilled into the pocket. Group 3 and 4 (study groups) received 0.1 and 0.2 mL of 1% methylene blue, respectively. On postoperative day 60, implants and capsular tissue were extracted. Capsule formation was evaluated both macroscopically and microscopically. The histological evaluation included capsule thickness, inflammation, neovascularization, and fibrosis gradients. Regarding capsule thickness, there were statistically significant differences between groups 1-3, 1-4, 2-3, and 2-4. Although there were more moderate and severe inflammation gradients in groups III and IV, there was no significant difference regarding inflammation severity between control and study groups. In respect of vascular proliferation, there was a statistically significant difference between control and study groups. Similarly, fibrosis gradients were higher in both groups 3 and 4. The study showed that the injection of methylene blue around silicone implants enhanced the formation of capsular contracture. In this case, the degree of contracture was independent of the dose given.Item The effect of nutrition theraphy on oxidative stress, inflammation, glycemic control in type 2 diabetes patients(2019) Colak, Gozde Aritici; Kiziltan, GulAims: Type 2 diabetes mellitus is a metabolism disease which is seen frequently among adult population in Turkey. The aim of this study was to determine the medical nutrition theraphy effect on oxidative stress, inflammation, glycemic control in type 2 diabetes patients. Methods: An interventional study was carried on 35 type 2 diabetes ages between 20-65 years old at the Department of Endocrinology of Baskent University Istanbul Hospital in 2015. In 3 month period a personal nutrition theraphy was applied. Biochemical parameters, anthropometric measurements and body analysis were also determined. The three day food consumption and biochemical parameters were requested at the beginning and at the end of the study. Results: When the impact of the blood values of the new medical nutrition theraphy which the patients practiced during the first visit and the follow up visit were compared; it was seen that there was a significant decrease on fasting plasma glucose, fasting insulin, HbA1c, CRP, TG and MDA values (p<0.05). The mean diabetic age of the patients was 7.63 +/- 6.22 years. When diabetic age of the patients was increased, there was a positive correlation between the fasting plasma glucose and HbA1c values (p<0.05). Conclusions: Type 2 diabetes patients were evaluated 3 month of medical nutrition theraphy and it was seen that the personal medical nutritional theraphy contributed to providing glisemic control and decreasing oxidative stress and inflammation.Item The impact of endometriosis on fertility(2015) Haydardedeoglu, Bulent; Zeyneloglu, Hulusi Bulent; 26448139Although the prevalence of endometriosis in infertile women seemed to be nearly 50%, all women with endometriosis are not infertile...
