    Effectiveness of a clinical pathway for acute stroke care in a district general hospital: an audit

    BACKGROUND: Organised stroke care saves lives and reduces disability. A clinical pathway might be a form of organised stroke care, but the evidence for the effectiveness of this model of care is limited. METHODS: This study was a retrospective audit study of consecutive stroke admissions in the setting of an acute general medical unit in a district general hospital. The case-notes of patients admitted with stroke for a 6-month period before and after introduction of the pathway, were reviewed to determine data on length of stay, outcome, functional status, (Barthel Index, BI and Modified Rankin Scale, MRS), Oxfordshire Community Stroke Project (OCSP) sub-type, use of investigations, specific management issues and secondary prevention strategies. Logistic regression was used to adjust for differences in case-mix. RESULTS: N = 77 (prior to the pathway) and 76 (following the pathway). The median (interquartile range, IQR) age was 78 years (67.75–84.25), 88% were European NZ and 37% were male. The median (IQR) BI at admission for the pre-pathway group was less than the post-pathway group: 6 (0–13.5) vs. 10 (4–15.5), p = 0.018 but other baseline variables were statistically similar. There were no significant differences between any of the outcome or process of care variables, except that echocardiograms were done less frequently after the pathway was introduced. A good outcome (MRS<4) was obtained in 66.2% prior to the pathway and 67.1% after the pathway. In-hospital mortality was 20.8% and 23.1%. However, using logistic regression to adjust for the differences in admission BI, it appeared that admission after the pathway was introduced had a significant negative effect on the probability of good outcome (OR 0.29, 95%CI 0.09-0.99). CONCLUSION: A clinical pathway for acute stroke management appeared to have no benefit for the outcome or processes of care and may even have been associated with worse outcomes. These data support the conclusions of a recent Cochrane review

    A spatially resolved analysis of star-formation burstiness by comparing UV and Hα\alpha in galaxies at z∼\sim1 with UVCANDELS

    The UltraViolet imaging of the Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey Fields (UVCANDELS) program provides HST/UVIS F275W imaging for four CANDELS fields. We combine this UV imaging with existing HST/near-IR grism spectroscopy from 3D-HST+AGHAST to directly compare the resolved rest-frame UV and Hα\alpha emission for a sample of 979 galaxies at 0.7<z<1.50.7<z<1.5 spanning a range in stellar mass of 108−11.5 M⊙10^{8-11.5}~M_\odot. Since both rest-UV and Hα\alpha are sensitive to on-going star-formation but over different timescales, their resolved comparison allows us to infer the burstiness in star-formation as a function of galaxy structural parameters. We generate homogenized maps of rest-UV and Hα\alpha emission for all galaxies in our sample and stack them to compute the average UV-to-Hα\alpha luminosity ratio as a function of galactocentric radius. We find that galaxies below stellar mass of ∼109.5 M⊙\sim10^{9.5}~M_\odot, at all radii, have a UV-to-Hα\alpha ratio higher than the equilibrium value expected from constant star-formation, indicating a significant contribution from bursty star-formation. Even for galaxies with stellar mass ≳109.5M⊙\gtrsim10^{9.5} M_\odot, the UV-to-Hα\alpha ratio is elevated towards in their outskirts (R/Reff>1.5R/R_{eff}>1.5), suggesting that bursty star-formation is likely prevalent in the outskirts of even the most massive galaxies but is likely over-shadowed by their brighter cores. Furthermore, we present the UV-to-Hα\alpha ratio as a function of galaxy surface brightness, a proxy for stellar mass surface density, and find that regions below ∼108 M⊙ kpc−2\sim10^8~M_\odot~kpc^{-2} are consistent with bursty star-formation, regardless of their galaxy stellar mass, potentially suggesting that local star-formation is independent of global galaxy properties at the smallest scales.Comment: 19 pages, 8 figures; submitted to Ap

    The Science of Pronominal Usage: He and It in Co-Reference to Inanimate Objects in Late Middle English Texts on Alchemy

    This is the author's accepted manuscript. The published version can be found at http://dx.doi.org/10.1177/0075424210384225This article explores the variation between he and it in coreference to inanimate entities (such as mercury, sulfur, and salt). Using alchemical texts from the fifteenth century as material, the article demonstrates that there was much more variation in pronominal reference in this period than has previously been shown. Of the possible explanations suggested by previous research, the earlier grammatical gender system and transference from Latin do not seem to play a role, while pronoun clustering and pronominal reanalysis appear to influence the quantitative distribution. The scale of individuation used by Siemund and Stenroos to explain similar usage is shown not to be a straightforward predictor. Other factors such as personification and perceived similarities between animate and inanimate entities may affect the degree of perceived individuation. The choice of he over she seems to be influenced by pronominal reanalysis and straightforward personification in some cases. In other instances, it is speculated that the he usage reflects (stereotypical) gender conceptions in the Middle Ages

    Oxr1 Is Essential for Protection against Oxidative Stress-Induced Neurodegeneration

    Oxidative stress is a common etiological feature of neurological disorders, although the pathways that govern defence against reactive oxygen species (ROS) in neurodegeneration remain unclear. We have identified the role of oxidation resistance 1 (Oxr1) as a vital protein that controls the sensitivity of neuronal cells to oxidative stress; mice lacking Oxr1 display cerebellar neurodegeneration, and neurons are less susceptible to exogenous stress when the gene is over-expressed. A conserved short isoform of Oxr1 is also sufficient to confer this neuroprotective property both in vitro and in vivo. In addition, biochemical assays indicate that Oxr1 itself is susceptible to cysteine-mediated oxidation. Finally we show up-regulation of Oxr1 in both human and pre-symptomatic mouse models of amyotrophic lateral sclerosis, indicating that Oxr1 is potentially a novel neuroprotective factor in neurodegenerative disease
