Cure, Medine Cumhur/0000-0001-9253-6459; cure, erkan/0000-0001-7807-135XWOS: 000332681100003PubMed: 24624344Background: Vitamin D deficiency and a high mean platelet volume (MPV) are related to cardiovascular disease. We investigated whether vitamin D deficiency is associated with high MPV. Methods: This study included 434 patients without chronic disease who were not taking vitamin D or calcium supplements. Vitamin D was measured by chemiluminescent microparticle immunoassay on the Architect-I2000 system (Abbott Diagnostics, USA), and MIN was measured on the Cell-Dyn Ruby analyzer (Abbott Diagnostics). Patients were divided into Groups 1 (138 [men/women, 46/92]), 2 (148 [men/women, 54/94]), and 3 (148 [men/women, 50/98]) according to vitamin D levels of 20 ng/mL, respectively. Results: the vitamin D level in Group 1 (7.7 +/- 1.9 ng/mL) was lower than that in Group 2 (15.1 +/- 1.6 ng/mL, P<0.001) and Group 3 (25.6 +/- 6.3 ng/mL, P<0.001). the MPV in Group 3 (7.5 +/- 1.0 fL) was lower than that in Group 1 (8.1 +/- 1.1 fL, P<0.001) and Group 2 (7.9 +/- 1.0 fL, P=0.009). Linear regression analysis showed that low levels of vitamin D (beta = -0.109, P = 0.019) was independently associated with increased MPV. Conclusions: There was a strong association between a low vitamin D level and a high MPV; therefore, vitamin D deficiency may be associated with increased MPV

Topiramate has protective effect on renal injury

We investigated protective effects of TPM on cell damage in kidney tissue during ischemia-reperfusion (I/R) damage. Methods: A total of 30 male Wistar albino rats were divided into three groups: control, I/R, and I/R plus TPM (I/R+TPM). Laparotomy without I/R injury was performed in control group. After laparotomy, cross ligation of infrarenal abdominal aorta was applied for two hours in I/R groups which was followed by two hours of reperfusion. TPM (100 mg/kg/day) was orally administrated to animals in the I/R+TPM group for seven consecutive days before I/R. Results: the I/R group's TNF-a and interleukin-1 beta (IL-1(3) levels were significantly higher (1184.2 +/- 129.1 pg/mg protein; 413.1 +/- 28.8 pg/mg protein, respectively) than those of the control (907.8 +/- 113.0 pg/mg protein, p = 0.002; 374.7 +/- 23.7 pg/mg protein, p = 0.010, respectively) and I/R+TPM groups (999.5 +/- 115.2 pg/mg protein, p < 0.001; 377.9 +/- 30.9 pg/mg protein, p = 0.007, respectively). Conclusion: TPM may partially prevent renal damage in rats. the opening of new horizons of this kind of knowledge will help understand the complex challenge in the prevention of renal I/R damage (Tab. 1, Fig. 3, Ref. 42).
