Item Evaluation of Electrodermal Activity and Anxiety Behaviors in Diabetic Rats Given Vildagliptin and Metformin(2022) Shawesh, Muftah; Alshareef, Mohammed; Boyuk, Gulbahar; Yigit, Ayse Arzu; Dolu, NazanItem Prognostic Factors in Squamous Cell Carcinoma of the Vulva: a Retrospective Multicenter Study(2020) Kuru, Oguzhan; Akgor, Utku; Cakir, Ilker; Tosun, Ozgur; Yuksel, Ilkbal Temel; Ulker, Volkan; Meydanli, Mutlu; Sanci, Muzaffer; Gokcu, Mehmet; Topuz, Samet; Yildiz, Ferah; Sakinci, Mehmet; Salman, Mehmet Coskun; Ozgul, Nejat; Yuce, Kunter; Ayhan, Ali; AAJ-5802-2021The study aim to determine the clinicopathological factors for disease-free survival (DFS) and overall survival (OS) in women with vulvar cancer and to analyze the the possible effect of metformin on survival of the patients. From 2011 to 2017, medical records of 142 patients who underwent primary radical surgery for VC at 6 referral centers in Turkey were collected, retrospectively. The median age of the cohort was 67.0 years. 124 patients underwent radical surgery and inguinofemoral lymphadenectomy. The overall recurrence rate was 33.8% within a median follow-up time of 22 months. Five-year DFS and OS rates were 55.8% and 62.6%, respectively. Multivariate analysis showed surgical margin (HR:6.4, p= 0.017 for DFS; HR: 13.6, p=0.009 for OS) and lymph node metastasis (HR: 4.1, p= 0.014 for DFS; HR: 6.3, p= 0.020 for OS) were the independent prognostic factors. There was no statistically difference in DFS and OS for patients who had used metformin.Item Metformin Decreases Thyroid Volume and Nodule Size in Subjects with Insulin Resistance: A Preliminary Study(2016) Anil, Cuneyd; Kut, Altug; Atesagaoglu, Berna; Nar, Asli; Tutuncu, Neslihan Bascil; Gursoy, Alptekin; 26618447Objective: The aim of this study was to investigate the effects of metformin on thyroid volume and nodule size. Subjects and Methods: Prospective data were gathered on 100 newly diagnosed subjects with insulin resistance (68 female, 32 male) between August 2008 and May 2010. Each subject followed a standard diet and exercise program, and received 1,700 mg/day of metformin therapy for 6 months. The height, weight, waist circumference (WC) and thyroid hormone levels of each subject were measured. Additionally, the dimensions of the thyroid lobes and maximum diameter of each thyroid nodule were determined by ultrasonography. BMI and thyroid volumes were also calculated. Insulin resistance was estimated by homeostasis model assessment. All these parameters were measured at the beginning and at the end of the treatment period. Results: BMI and WC decreased significantly after metformin therapy (34.5 +/- 5.1 vs. 32.7 +/- 4.8, p < 0.0001, and 106.3 +/- 11.8 vs. 101.8 +/- 19.0 cm, p = 0.008, respectively). Insulin resistance also decreased after metformin therapy (4.5 +/- 1.9 vs. 2.9 +/- 1.7, p < 0.0001). The mean thyroid volume (22.5 +/- 11.2 vs. 20.3 +/- 10.4 ml, p < 0.0001) and mean thyroid nodule size (12.9 +/- 7.6 vs. 11.7 +/- 7.2 mm, p < 0.0001) also decreased after treatment. Conclusion: In subjects with insulin resistance, metformin therapy significantly decreased thyroid volume and nodule size. (C) 2015 S. Karger AG, BaselItem Metformin: Hype or Hope for Cancer(2017) Nar, Asli; 0000-0003-0998-8388; AAA-2743-2021Current studies show that especially pancreatic, liver, endometrial, colorectal, bladder and breast cancer incidences are increased by the presence of type 2 diabetes mellitus (T2DM). Possible links between T2DM and cancer include hyperinsulinemia, dysregulation of adipocytokines and hyperglycemia as well as shared confounding risk factors. There is evidence emerging from experimental and clinical studies that metformin can play a crucial anti-cancereous role. Since 2005, multiple studies showed the association between metformin and the reduction of risk in cancers of pancreas, colorectal, stomach, liver, breast and esophagus in diabetes cases. It was also claimed to improve survival in some cancers. Metformin is an insulin sensitizer and mainly acts through inhibiting hepatic gluconeogenesis by activating LKB1/AMP-activated protein kinase (AMPK). Metformin was found to have anti-cancerous and anti-metastatic effects mainly through activating AMPK dependent and independent signaling; inhibiting mTOR, MAPK, HER2, NF-kappa B, IGF signaling pathways and with its possible immuno-modulatory effects. Further studies are needed to evaluate the potential of metformin as adjuvant therapy for cancer especially in non-diabetic patients.
