- Aim: The relationship between depression in adolescents and vitamin D was studied in a case-series that included effects of vitamin D supplementation. Methods: Serum 25OH vitamin D (25OHD) levels in 54 Swedish depressed adolescents were investigated. Subjects with vitamin D deficiency were given vitamin D3 over 3 months (n = 48). To evaluate well-being and symptoms related to depression and vitamin D status, the WHO-5 well-being scale, the Mood and Feelings Questionnaire (MFQ-S) and a vitamin D deficiency scale were used. Results: Mean serum 25OHD in the depressed adolescents was 41 at baseline and 91 nmol/L (p < 0.001) after supplementation. Basal 25OHD levels correlated positively with well-being (p < 0.05). After vitamin D supplementation, well-being increased (p < 0.001) and there was a significant improvement in eight of the nine items in the vitamin D deficiency scale: depressed feeling (p < 0.001), irritability (p < 0.05), tiredness (p < 0.001), mood swings (p < 0.01), sleep difficulties (p < 0.01), weakness (p < 0.01), ability to concentrate (p < 0.05) and pain (p < 0.05). There was a significant amelioration of depression according to the MFQ-S (p < 0.05). Conclusion: This study showed low levels of vitamin D in 54 depressed adolescents, positive correlation between vitamin D and well-being, and improved symptoms related to depression and vitamin D deficiency after vitamin D supplementation.

- Aim: Solid tumours constitute 40% of childhood malignancies. The Swedish Childhood Cancer Registry is population-based and includes all children with cancer reported from the six paediatric oncology centres in Sweden. The aim was to investigate incidence and survival. Methods: We used the new WHO ICCC-3 for reclassification of the patients. Incidence and survival analyses were performed in the study population. Results: 2 487 children (< 15 years) were diagnosed with solid tumours in Sweden 1983 - 2007. The distribution of diagnoses was similar to that reported in other studies. The annual incidence was 65.3/million children. The survival rates at 10 years follow up have improved significantly when comparing the two time periods 1983-95 and 1995-2007 (76 vs. 82%; p<0.01). Conclusions: The mean annual incidence of solid tumours in children was 65.3/ million and has been stable during the study period. Survival rates for solid tumours at 5, 10 and 20 years follow up were 80, 79 and 76%, respectively.

The aim was to investigate incidence and survival. Methods: We used the new WHO ICCC-3 for reclassification of the patients. Incidence and survival analyses were performed in the study population. Results: Two thousand four hundred and eighty-seven children (< 15 years) were diagnosed with solid tumours in Sweden between 1983 and 2007. The distribution of diagnoses was similar to that reported in other studies. The annual incidence was 65.3 per million children. The survival rates at 10 years of follow-up have improved significantly when comparing the two time periods, 1983-1995 and 1995-2007 (76 vs. 82%; p < 0.01). Conclusions: The mean annual incidence of solid tumours in children was 65.3/million and has been stable during the study period.

Fast-switching all-printed organic electrochemical transistors

- Symmetric and fast (∼5 ms) on-to-off and off-to-on drain current switching characteristics have been obtained in screen printed organic electrochemical transistors (OECTs) including PEDOT:PSS (poly(3,4-ethylenedioxythiophene) doped with poly(styrene sulfonic acid)) as the active transistor channel material. Improvement of the drain current switching characteristics is made possible by including a carbon conductor layer on top of PEDOT:PSS at the drain electrode that is in direct contact with both the channel and the electrolyte of the OECT. This carbon conductor layer suppresses the effects from a reduction front that is generated in these PEDOT:PSS-based OECTs. In the off-state of these devices this reduction front slowly migrate laterally into the PEDOT:PSS drain electrode, which make off-to-on switching slow. The OECT including carbon electrodes was manufactured using only standard printing process steps and may pave the way for fully integrated organic electronic systems that operate at low voltages for applications such as logic circuits, sensors and active matrix addressed displays.
