Based on the limited reports of arterial extravasation in the nonhelical CT literature, the percentage (18%) of clinically stable patients in our study with CT scans showing arterial extravasation was higher than anticipated. This finding likely reflects the improved diagnostic capability of helical CT. Although the spleen and liver were the organs most commonly associated with arterial extravasation, radiologists should be aware that arterial extravasation may be associated with several other visceral injuries.
This paper reports the synthesis, crystal structure, surface morphology, optical and electrical properties of Mgdoped Sn2S3 thin films deposited by spray pyrolysis technique. All the films exhibit orthorhombic crystal structure with a (211) preferential orientation. Crystallite size calculations based on the Debye-Scherrer formula indicated that the Sn2S3 crystallite size increases with Mg content from 27.97 nm to 33.58 nm. Scanning electron microscopy images showed that all the films were very smooth composed of nanoneedle and nanoplate shaped grains. The band gap energy of the films exhibits a blue shift from 1.94 eV to 2.09 eV with increase in Mg concentration. Resistivity values of the undoped and Mg-doped Sn2S3 films were found to be in the order of 0.1 Ωcm. From the obtained results it is observed that the Sn2S3 film coated with 2 wt% Mg concentration exhibits better physical properties.
Objective: Evidence suggests the increased prevalence of diabetes among South Asian (SA) adolescents is due to their genetic risk profile. The South Asian Adolescent Diabetes Awareness Program (SAADAP) is a pilot intervention for SA youth in Canada with a family history of type 2 diabetes mellitus (T2DM). We sought to investigate changes in (1) diabetes knowledge and associated risk factors, (2) risk perception and (3) health behaviours among adolescents participating in SAADAP. Design: One-group pre-test, post-test design informed by a commitment to community-based participatory research (CBPR). Setting: Sixty-eight adolescents aged 13–17 years with a family history of T2DM participated in SAADAP in a clinical-community setting in Canada. Method: Pre–post questionnaires were administered to evaluate diabetes knowledge and associated risk factors, risk perceptions and health behaviours. Analyses were restricted to 49 participants who attended at least four diabetes education sessions. Results: The mean age of adolescents was 14.5 years, and 57.1% self-identified as girls. The difference in knowledge about the definition, symptoms and complications of T2DM from baseline to post-intervention was 3.32 out of 21 ( p < .001) among SA youth. There was significant increase in learning about diabetes risk factors ( p < .001) from baseline to post-intervention. Almost 60% of participants exhibited no change in their risk perception after intervention. Approximately two-thirds of the participants self-reported positive changes in health behaviours after completing the programme. Conclusion: SAADAP showed promising outcomes in raising knowledge and improving health behaviours in SA adolescents with a family history of diabetes. Larger controlled trials with longer follow-up are recommended to support and expand on the current findings.
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.
