Supplementary Material for: Association of Genetic Polymorphisms for Glutathione Peroxidase Genes with Obesity in Spanish Children

<b><i>Background/Aims:</i></b> Altered expression and activity of the antioxidant enzymes glutathione peroxidases (GPXs) have been observed in obesity in human and animal studies. We aimed to study 59 single nucleotide polymorphisms (SNPs) for <i>GPX1-7</i> genes and to characterize their association with prepubertal childhood obesity and its associated biomarkers. <b><i>Methods:</i></b> This case-control study included 193 obese and 191 normal-weight prepubertal Spanish children, in whom anthropometry, biochemical parameters, adipokines, antioxidant enzyme erythrocyte activities and biomarkers of oxidative stress, inflammation and cardiovascular risk were measured. The genotype analysis was performed in the Illumina platform. PLINK and SPSS were used for statistical analyses. <b><i>Results:</i></b> We found SNPs rs757228 and rs8103188 <i>(GPX4) </i>to be negatively associated and rs445870 <i>(GPX5)</i> and rs406113 <i>(GPX6)</i> to be positively associated with obesity in children. The variant rs2074451 (<i>GPX4</i>) increased GPX activity in erythrocytes. Although we did not find significant differences in erythrocyte GPX activity between obese and normal-weight children, GPX activity was found to be positively and significantly correlated with blood pressure, adipocyte fatty acid-binding protein and high-sensitivity C-reactive protein. <b><i>Conclusions:</i></b> The GPX variants rs757228, rs8103188, rs445870 and rs406113 were associated with prepubertal childhood obesity. However, erythrocyte GPX activity was not altered in obese prepubertal Spanish children

Supplementary Material for: Endovascular Treatment of Distal Internal Carotid Artery Occlusions with Retrievable Stents

<b><i>Background:</i></b> Acute stroke due to distal intracranial internal carotid artery (ICA) occlusion has a poor natural history. Outcome in patients who receive intravenous tissue plasminogen activator (tPA) is also unsatisfactory. The objective of this study is to evaluate the effectiveness and safety of endovascular treatment with retrievable stents in these patients. <b><i>Methods:</i></b> Data from a prospective register of patients with acute stroke treated with an endovascular procedure in a single centre were analysed. <b><i>Results:</i></b> A total of 20 patients with distal ICA occlusion were collected. Mean baseline National Institutes of Health Stroke Scale score was 18. Eight cases (40%) had received previous intravenous tPA. Mean time from stroke to recanalization was 393 min. Retrievable stents with proximal occlusion and aspiration were used in all cases. In 3 patients, 2 retrievable stents were used simultaneously. Complete recanalization (thrombolysis in cerebral infarction 2b/3) was accomplished in 85% of cases. A favourable clinical outcome (modified Rankin Scale score 0-2) was achieved in 13 patients (65%). Mortality occurred in 2 cases (10%). <b><i>Conclusions:</i></b> Endovascular treatment of patients with distal ICA occlusion seems safe and effective. Retrievable stents may be the treatment of choice, although randomized clinical trials are necessary. The use of 2 retrievable stents at the same time could be an alternative technique useful in thrombi of larger size
