- Islet beta cell adaptation to dexamethasone-induced insulin resistance was characterized with respect to glucose-stimulated insulin secretion and islet innervation. Male Sprague-Dawley rats were injected daily with dexamethasone (2 mg/kg for 12 days), which resulted in hyperinsulinemia and hyperglycemia compared with controls (which were injected with sodium chloride). Insulin secretion was characterized in collagenase-isolated islets. Islet innervation was examined by immunocytochemical analysis of tyrosine hydroxylase, neuropeptide Y (sympathetic nerves), and vasoactive intestinal polypeptide (cholinergic nerves). In islets isolated from the insulin-resistant animals, the insulin response to 3.3 or 8.3 mM glucose was three times greater during perifusion compared with controls (p < 0.001). Incubation of islets at 0 to 20 mM glucose revealed a marked leftward shift of the glucose dose-response relation after dexamethasone treatment (potency ratio, 1.78; p < 0.01), with no difference at 0 or 20 mM glucose. Thus, the potency but not the efficacy of glucose was increased. The number of islet nerves did not differ between dexamethasone-treated rats and controls. Dexamethasone-induced insulin resistance leads to adaptively increased glucose responsiveness of the islet beta cells, with increased potency, but not increased efficacy, of glucose to stimulate insulin secretion without any evidence of altered islet innervation.

Forskningsöversikt (refereegranskat)abstract
- Background: Complementary alternative medicine (CAM) is widely used among patients with cancer. This usage may have potentially harmful effects, especially when combined with anticancer drugs. However, some complementary methods may benefit patients. This review investigated the prevalence of CAM use among patients with cancer in Scandinavia and secondly studied the educational levels of CAM users compared to non-users. Materials and Methods: A systematic search of the PubMed library was carried out to locate articles published between January 2000 and October 2015 that investigated prevalence of CAM use among Scandinavian patients with cancer. Results: Twenty-two articles were found, of which nine were included in the review. The prevalence of CAM use was 7.9% to 53%, with an average of 36.0% across all studies. Conclusion: Use of CAM is widespread among patients with cancer. Knowledge about CAM should be disseminated to both patients and staff in order to optimise discussions about CAM in clinical practice.

Correlates of Orthographic Learning in Swedish Children With Cochlear Implants

Tidskriftsartikel (refereegranskat)abstract
- This study set out to explore the cognitive and linguistic correlates of orthographic learning in a group of 32 deaf and hard of hearing children with cochlear implants, to better understand the factors that affect the development of fluent reading in these children. To date, the research about the mechanisms of reading fluency and orthographic learning in this population is scarce. The children were between 6:0 and 10:11 years of age and used oral language as their primary mode of communication. They were assessed on orthographic learning, reading fluency and a range of cognitive and linguistic skills including working memory measures, word retrieval and paired associate learning. The results were analyzed in a set of correlation analyses. In line with previous findings from children with typical hearing, orthographic learning was strongly correlated with phonological decoding, receptive vocabulary, phonological skills, verbal-verbal paired-associate learning and word retrieval. The results of this study suggest that orthographic learning in children with CI is strongly dependent on similar cognitive and linguistic skills as in typically hearing peers. Efforts should thus be made to support phonological decoding skill, vocabulary, and phonological skills in this population.
