‘He's a Cracking Wee Geezer from Pakistan’: Lay Accounts of Refugee Integration Failure and Success in Scotland

Previous research on the integration of asylum seekers and refugees has aimed to develop conceptual frameworks for understanding integration or to measure the extent to which people are integrated. However, this research tends to pay insufficient attention to the rhetorical functions of integration discourse. The current study addresses this gap through a discursive analysis of ‘lay’ accounts of asylum seeker and refugee integration in Glasgow, Scotland. The analysis highlights that accounts of integration ‘failure’ may support ‘two-way’ conceptions of integration while still blaming asylum seekers for any lack of integration. Furthermore, accounts of integration ‘success’ may reinforce assimilationist policies or otherwise function to reinforce the view that adult asylum seekers generally do not integrate. The analysis highlights the importance of attending to the rhetorical functions of integration discourse in order to understand how particular policies and practices are supported or criticised at the community level at which integration takes place

Pulmonary availability of isotretinoin in rats after inhalation of a powder aerosol

Repeated oral administration of chemopreventive retinoids such as isotretinoin over extended periods of time is associated with intolerable systemic toxicity. Here isotretinoin was formulated as a powder aerosol, and its delivery to the lungs of rats was studied with the aim to explore the possibility of minimizing adverse effects associated with its oral administration. Rats received isotretinoin orally (0.5, 1 or 10 mg kg–1) or by inhalation (theoretical dose ~1 or ~10 mg kg–1) in a nose-only inhalation chamber. Isotretinoin was quantitated by high-pressure liquid chromatography in plasma and lung tissue. The ratios of mean area of concentration-vs-time curve (AUC) values in the lungs over mean AUCs in the plasma for isotretinoin following single or repeated aerosol exposure surpassed those determined for the oral route by factors of between two (single low-dose) and five (single high-dose). Similarly, the equivalent ratios for the maximal peak concentrations in lungs and plasma obtained after aerosol exposure consistently exceeded those seen after oral administration, suggesting that lungs were exposed to higher isotretinoin concentrations after aerosol inhalation than after oral administration of similar doses. Repeated high doses of isotretinoin by inhalation resulted in moderate loss of body weight, but microscopic investigation of ten tissues including lung and oesophagus did not detect any significant aerosol-induced damage. The results suggest that administration of isotretinoin via powder aerosol inhalation is probably superior to its application via the oral route in terms of achieving efficacious drug concentrations in the lungs. © 2000 Cancer Research Campaig

Pharmacology as a foreign language: A preliminary evaluation of podcasting as a supplementary learning tool for non-medical prescribing students

<p>Abstract</p> <p>Background</p> <p>Nurses and other health professionals in the U.K. can gain similar prescribing rights to doctors by undertaking a non-medical prescribing course. Non-medical prescribing students must have a thorough understanding of the pharmacology of prescribing to ensure safe practice. Pharmacology education at this level is complicated by the variation in students' prior subject knowledge of, and anxiety about, the subject. The recent advances in technology, particularly the potential for mobile learning, provide increased opportunities for students to familiarise themselves with lecture materials and hence promote understanding. The objective of this study was therefore to evaluate both the subjective (student perception) and objective (student use and exam results) usefulness of podcasts of pharmacology lectures which were provided as an extra learning tool to two cohorts (n = 69) of non-medical prescribing students.</p> <p>Methods</p> <p>The podcasts were made available to students through the virtual learning environment WebCT. Use of podcasts by two successive cohorts of nurse prescribing students (n = 69) was tracked through WebCT. Survey data, which was collected from 44 of these students, investigated patterns of/reasons for podcast use and perceived usefulness of podcasts as a learning tool. Of these 69 students, 64 completed the pharmacology exam. In order to examine any impact of podcasts on student knowledge, their exam results were compared with those of two historical cohorts who did not have access to podcasts (n = 70).</p> <p>Results</p> <p>WebCT tracking showed that 91% of students accessed at least one podcast. 93% of students used the podcasts to revisit a lecture, 85% used podcasts for revision, and 61% used the podcasts when they had a specific question. Only 22% used the podcasts because they had missed a pharmacology session. Most students (81%) generally listened to the entire podcast rather than specific sections and most (73%) used them while referring to their lecture handouts. The majority of students found the podcasts helpful as a learning tool, as a revision aid and in promoting their understanding of the subject. Evaluation of the range of marks obtained, mode mark and mean mark suggested improved knowledge in students with access to podcasts compared to historical cohorts of students who did not have access to pharmacology podcasts.</p> <p>Conclusions</p> <p>The results of this study suggest that non-medical prescribing students utilised podcasts of pharmacology lectures, and have found the availability of these podcasts helpful for their learning. Exam results indicate that the availability of podcasts was also associated with improved exam performance.</p

Measuring facial swelling using three-dimensional imaging

Requirements exist clinically for quantitative analysis of facial swelling. A quick and non-invasive measurement of facial volume is desirable. The acquisition of three-dimensional images, corresponding to spatial models of patients' facial surfaces, has been facilitated using a Spatial Vision System (SVS) developed by Thorn EMI Central Research Laboratories (UK). The SVS acquires four video images (two stereo pairs) and constructs a three-dimensional surface representation using stereo matching of spatial features acquired using 'speckled' illumination. Pre- and post-operative binary volumetric images are then spatially aligned using surface matching algorithms. Accuracy of registration is optimized using Match Volume Excavation. Segmentation of post-operative swelling is achieved by volume differencing in combination with morphological erosion. Volumetric quantification is achieved using a method of three-dimensional region growing, giving the number of connected voxels in the image volume from a user selected seed point. Accuracy of image acquisition has been quantified by imaging a range of hemispherical phantoms of known volumes. The mean error in repeated measurement of volume was found to be within 3.5%. The perception of temporal changes in facial swelling is highly subjective. Further work is being undertaken to develop an Enhanced Reality visualization tool in which graphical swelling annotations are combined with real-time patient images.10 page(s

A study on the chiral inversion of mandelic acid in humans

Mandelic acid is a chiral metabolite of the industrial pollutant styrene and is used in chemical skin peels, as a urinary antiseptic and as a component of other medicines. In humans, S-mandelic acid undergoes rapid chiral inversion to R-mandelic acid by an undefined pathway but it has been proposed to proceed via the acyl-CoA esters, S- and R-2-hydroxy-2-phenylacetyl-CoA, in an analogous pathway to that for Ibuprofen. This study investigates chiral inversion of mandelic acid using purified human recombinant enzymes known to be involved in the Ibuprofen chiral inversion pathway. Both S- and R-2-hydroxy-2-phenylacetyl-CoA were hydrolysed to mandelic acid by human acyl-CoA thioesterase-1 and -2 (ACOT1 and ACOT2), consistent with a possible role in the chiral inversion pathway. However, human α-methylacyl-CoA racemase (AMACR; P504S) was not able to catalyse exchange of the α-proton of S- and R-2-hydroxy-2-phenylacetyl-CoA, a requirement for chiral inversion. Both S- and R-2-phenylpropanoyl-CoA were epimerised by AMACR, showing that it is the presence of the hydroxy group that prevents epimerisation of R- and S-2-hydroxy-2-phenylacetyl-CoAs. The results show that it is unlikely that 2-hydroxy-2-phenylacetyl-CoA is an intermediate in the chiral inversion of mandelic acid, and that the chiral inversion of mandelic acid is via a different pathway to that of Ibuprofen and related drugs

The development and use of a triage protocol for patients with dental problems contacting an out-of-hours general medical practitioner cooperative

Purpose of the study: The number of patients contacting general medical practitioner (GMP) out-of-hours services with dental problems is perceived to be a significant problem by the medical profession. This study was undertaken to design and pilot a triage protocol that could be used by non-dental staff to refer callers with dental complaints for appropriate treatment. Basic procedures: A triage protocol was designed to address the patient conditions considered to be relevant to emergency dental care. The triage protocol was piloted for three months at a GMP cooperative in North Wales, which provided an out-of-hours service for 61 GMPs. Baseline data were collected for three months prior to the introduction of the triage protocol. Main findings: The study showed that the number of dental callers contacting the out-of-hours service was not as great as GMPs imagined, and was similar to other studies. The introduction of the triage protocol resulted in a rise in the number of callers asked to call the general dental practitioner (GDP) support line. The number of unregistered patients given the name of a dentist also increased. The need to make a second telephone call seemed not to affect patient satisfaction since when patients were later questioned on their experience, those who had used the service since the introduction of the triage protocol were more likely to be satisfied with the service. Principal conclusions: This study provides some evidence that a triage protocol can be used successfully by non-dental staff to sift requests for out-of-hours emergency dental care
