BACKGROUND Time to successful reperfusion is a critical prognostic factor for acute ischaemic stroke. Mechanical thrombectomy has become the gold standard treatment for emergent large vessel occlusion stroke. The timely delivery of this highly specialized procedure to patients outside of metropolitan centres presents a dilemma of inequity, with limited workflow data hindering benchmarking and service optimisation. AIM We sought to analyse key stroke treatment time parameters from a primary stroke centre existing in a regional centre within a hub-and-spoke delivery model in Victoria, Australia. METHODS Retrospective cohort study of patients transferred from a regional primary stroke centre to a metropolitan comprehensive stroke centre for mechanical thrombectomy between July 2016 and December 2018. Time workflow analysis was conducted from symptom onset to primary stroke centre departure. Estrogen chemical RESULTS 55 patients were included in this study with an average age of 70.2 years. Median National Institutes of Health Stroke Scale score on admission was 13 (IQR 7-17). Median pre-hospital time was 68 min (IQR, 56-137) and median door-in-door-out time was 120.5 min (IQR, 98-150), constituting 36.1% and 63.9% of total median time from symptom onset to PSC departure (188.5 min) respectively. There were no significant differences across observed cohort characteristics under linear regression analysis. CONCLUSION Protracted pre-hospital and primary stroke centre workflow times can delay effective treatment for patients with acute ischaemic stroke in regional areas. A systems-level approach to streamlining processes in these key areas is required to bridge this inequity in best practice care. This article is protected by copyright. All rights reserved.

The field of pathogen detection is nascent and therefore, faces a dynamic set of challenges as the field evolves. Visceral leishmaniasis (VL), or kala-azar is the most severe form of leishmaniasis. Delay to the accurate diagnosis and treatment is likely to lead to fatality. The reliable, fast and sensitive detection is closely linked to safe and effective treatment of Leishmania spp. Despite several routine and old method for sensitive and specificity detection of Leishmania spp, there is highly demand for developing modern and powerfully system. In this study a novel ultra-sensitive DNA-based biosensor was prepared for detection of Leishmania spp. For the first time, the specific and thiolated sequences of the Leishmania spp genome (5'-SH-[CH2 ]6 ATCTCGTAAGCAGATCGCTGTGTCAC-3') were recognized by electrochemical methods. Also, selectivity of the proposed bioassay was examined by three sequences that were mismatched in 1, 2, and 3 nucleotides. The linear range (10-6 to 10-21 M) and limit of detection (LLOQ = 1 ZM) obtained are remarkable in this study. Also, simple and cost-effective construction of genosensors was another advantage of the proposal DNA-based assay. The experimental results promise a fast and simple method in detection of kala-azar patients with huge potential of the nanocomposite-based probe for development of ideal biosensors. © 2020 John Wiley & Sons Ltd.Graphdiyne (GDY) as a new carbon allotrope, possessing both sp- and sp 2- hybridized carbon atoms, has attracted extensive attention due to great application potentials in various fields. To realize fundamental understanding of the intrinsic properties of GDY, the controllable synthesis of ultrathin and high crystalline GDY is necessary and challenging. We reported herein a confined interfacial synthesis strategy towards high crystalline ultrathin GDY at water/oil/organogel interface with greatly improved control over GDY structures. The morphology and chemical composition of GDY was characterized accordingly. After loading with Au, the as-prepared hydrophobic Au/GDY system showed excellent performances in nitrogen reduction reaction (NRR), reaching highest yield of 4.15 μg·cm -2 ·h -1 with FE achieving 1.95% . © 2020 WILEY-VCH Verlag GmbH & Co.

Fifteen healthy adult toco toucans (Ramphastos toco), 10 females and 5 males, average body mass of 650 g were studied. CT examination as well as right lateral and ventrodorsal radiographic examinations of the coelomic cavity were performed under chemical restraint. Heart, lungs, air sacs, trachea and syrinx were analysed. The mean values of heart length, heart width and thoracic cavity in radiographs were, respectively, 23.76 mm, 25.94 mm and 48.87 mm. In both X-rays and CT scans, the lung parenchyma had honeycomb-like pattern. The topographic areas of the anterior and posterior air sacs were visualized as dark and air-filled spaces in X-rays. On CT evaluation, the air sacs occupied a larger area in the coelomic cavity compared to X-ray. In the lateral radiographic view, the cervical part of the trachea was positioned more ventrally in the transition from cervical to thoracic regions showing a V-shaped appearance. In all CT planes was visible division of the trachea into the right and left main bronchi at the level of 3rd thoracic vertebra. The syrinx was difficult to visualize in X-rays, but on CT it was easily identified in axial slice. In conclusion, the normal features of toco toucan's heart and lower respiratory tract that were determined on X-rays and CT scans are useful to compare with sick toco toucans, as well as other bird species. © 2020 Blackwell Verlag GmbH.OBJECTIVE As a malignant tumor with high mortality, lung cancer (LC) often causes great trauma to patients, and a series of negative emotions and a heavy psychological burden accompanies poor prognosis. Whether or not to inform the patients of their condition has always been a controversial topic in the medical community. This retrospective cohort study investigated the association between early informed diagnosis and survival time in patients with LC. METHODS A total of 29 825 patients with LC were enrolled between October 2002 and December 2016. The potential factors influencing LC survival were registered, including knowing their cancer diagnosis status, age, gender, pathological type, clinical stage, surgical history, hospital grade, and patient occupation. All participants were followed up every 6 months until June 2017. RESULTS In June 2017, 23.1% of the participants still survived. Their median survival time (MST) was 11.20 months (95% confidence interval [CI], 10.98-11.43). Generally, patients that knew their cancer diagnosis had longer MST than those who did not (18.
