Increasingly, children are engaging in early literacy experiences through digital devices. This raises questions about how electronic reading compares to print reading. To assess this, we randomly assigned 200 children (3–5 years) to be read the same book (1) with auto-narration on a tablet or 2) by a researcher from a print book. Reading was recorded and coded for behavioral and emotional engagement and vocalizations. Children were also tested on their story comprehension and vocabulary. Children had slightly higher posttest scores in the print condition. Older children and females also scored higher. There was an interaction between weekly tablet use and book platform. Children were equally engaged with the e-book and print book, but vocalized more about the device in the e-book condition. Findings suggest that e-books offer many of the same, but not all, of the educational affordance as print books. Additionally, novelty might be important in supporting comprehension.
Treatment of advanced pancreatic cancer has not improved substantially in recent years. The search for new agents or new therapeutic modalities may be critical for further development in the therapy of this disease. Experimental and clinical findings suggest that it might be possible to develop a new hormonal therapy for exocrine cancer of the pancreas based on new somatostatin analogues. Preliminary results indicate clinical activity and increased survival in some patients. In this study, 19 patients with advanced exocrine pancreatic carcinoma were given the somatostatin analogue BIM 23014 using a range of doses from 250 μg/day to 1 mg/day. One patient had a partial response, 6 patients had stable disease, and 11 had progressive disease. Six patients showed a sharp improvement in pain and performance status. Side effects were mild. Plasma levels of growth hormone were evaluated in ten patients and remained unchanged. The clinical activity observed, even if limited, warrants further investigation using more appropriate schedules and administration techniques.
A group of 73 patients with advanced renal cell carcinoma, treated in different phase II trials with interferon alpha and/or interleukin-2, have been evaluated to identify potential baseline prognostic factors predicting their survival. The eligibility criteria were very similar across studies and included ECOG performance status < or = 2, measurable or evaluable disease and no CNS metastases. The overall response rate was 8%. The overall survival was 33% at 2 years and 18% at 1 year. In the univariate analysis three prognostic factors were correlated with disease outcome: ECOG performance status (0 versus > or = 1), time from diagnosis to treatment (< or = 12 months versus > 12 months) and number of metastatic sites (1 versus > or = 2). Multivariate analysis identified ECOG performance status and number of metastatic sites as important prognostic factors for survival. The true impact on patient survival of the selection of patients rather than the treatment itself should be evaluated in controlled trials.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
