  Objectives Those affected with epilepsy have long been subject to stigmatization. This may have manifold negative effects, for example social isolation, low self-esteem, reduced quality of life and worsening of seizures. In Norway educational programs have been arranged at the National Centre for Epilepsy, aiming at reducing stigma and shame associated with epilepsy, and thereby increase the quality of life for those affected and their families. Thus, we wanted to explore the extent of self-reported perceived stigma and experienced discrimination in a Norwegian cohort with epilepsy. Materials and Methods We conducted a web-based questionnaire survey in Norway. Participants were asked to provide background and epilepsy-related information. In addition, they were encouraged to answer questions regarding felt stigmatization in different situations and to rate stigma according to the Jacoby stigma scale. Results Of 1182 respondents, 56% reported to have felt being stigmatized, and 35% reported to have experienced discrimination solely on the ground of the disease. 70% of respondents reported at least one type of perceived or experienced stigma. After controlling for gender, age, perceived depression and seizure freedom, reports of experienced stigmatization was a statistically significant independent predictor for reduced quality of life. Conclusions A considerable proportion of people with epilepsy in Norway feel stigmatized and/or subject to discrimination, which negatively affects their quality of life.

  In this double-blind, randomised, controlled trial, we investigated the effects of vitamin C and E supplementation on endurance training adaptations in humans. Fifty-four young men and women were randomly allocated to receive either 1000 mg of vitamin C and 235 mg of vitamin E or a placebo daily for 11 weeks. During supplementation, the participants completed an endurance training programme consisting of three to four sessions per week (primarily of running), divided into high-intensity interval sessions [4-6 × 4-6 min; >90% of maximal heart rate (HRmax)] and steady state continuous sessions (30-60 min; 70-90% of HRmax). Maximal oxygen uptake (VO2 max ), submaximal running and a 20 m shuttle run test were assessed and blood samples and muscle biopsies were collected, before and after the intervention. Participants in the vitamin C and E group increased their VO2 max (mean ± s.d.: 8 ± 5%) and performance in the 20 m shuttle test (10 ± 11%) to the same degree as those in the placebo group (mean ± s.d.: 8 ± 5% and 14 ± 17%, respectively). However, the mitochondrial marker cytochrome c oxidase subunit IV (COX4) and cytosolic peroxisome proliferator-activated receptor-γ coactivator 1 α (PGC-1α) increased in the m. vastus lateralis in the placebo group by 59 ± 97% and 19 ± 51%, respectively, but not in the vitamin C and E group (COX4: -13 ± 54%; PGC-1α: -13 ± 29%; P ≤ 0.03, between groups). Furthermore, mRNA levels of CDC42 and mitogen-activated protein kinase 1 (MAPK1) in the trained muscle were lower in the vitamin C and E group than in the placebo group (P ≤ 0.05). Daily vitamin C and E supplementation attenuated increases in markers of mitochondrial biogenesis following endurance training. However, no clear interactions were detected for improvements in VO2 max and running performance. Consequently, vitamin C and E supplementation hampered cellular adaptations in the exercised muscles, and although this did not translate to the performance tests applied in this study, we advocate caution when considering antioxidant supplementation combined with endurance exercise.
