Three tools for managing vertigo in the frontline

Vertigo is a challenging symptom in general practice. With access to three tools – a focused history, eye examination and a management algorithm – a large proportion of vertiginous patients could be managed effectively by GPs. This practical guide seeks to increase the skills and confidence of frontline practitioners when managing vertigo

Wetland Management Strategies that Maximize Marsh Bird Use in the Midwest: Annual Performance Report Period: 1 July 2016 – 30 June 2017

We determined marsh bird use across a wide range of wetland types (e.g., emergent, non-vegetated, riparian), hydrologic regimes (e.g., temporary, seasonal, semi-permanent), management practices (e.g., active, passive, unmanaged), and past disturbance regimes (e.g., natural and restored, impounded and unimpounded) in Illinois during late spring and early summer in 2015–2017. Our objectives were to 1) compare marsh bird use of restored and natural wetlands, 2) determine characteristics of wetlands and the surrounding landscape that influence marsh bird use of restored and natural wetlands, 3) compare marsh bird use of wetland impoundments managed for waterfowl across a continuum of management intensities and strategies to predict how these actions can increase use by both waterfowl and marsh birds. Additionally, we surveyed marsh birds using the standard protocols on wetlands concurrently surveyed within the Illinois Critical Trends Assessment Program (CTAP) for comparison of methodologies. We will provide marsh bird and other wetland-associated bird data to the Midwest Avian Data Center and the Avian Knowledge Network (AKN) and other conservation partners.Our data will be used as a basis for establishment of multi-group management strategies for marsh birds in the Midwest. These data will be especially useful as the Illinois Department of Natural Resources (IDNR) finalizes their Wetlands Campaign and Conservation Strategy as part of the Illinois Comprehensive Wildlife Conservation Plan and Strategy (i.e., wildlife action plan; ICWCPS). Moreover, our research addresses several priorities outlined in the Midwest bird monitoring framework outlined by Koch et al. (2010), including furthering understanding of the ecology and conservation priorities for migrating birds, evaluating effectiveness of conservation actions such as wetland restoration, and increasing access to bird data relative to landscape characteristics for use in conservation planning.Unites States Fish and Wildlife Service Contract Number: F14AP00485unpublishednot peer reviewedOpe

Assessment of a novel, capsid-modified adenovirus with an improved vascular gene transfer profile

<p>Background: Cardiovascular disorders, including coronary artery bypass graft failure and in-stent restenosis remain significant opportunities for the advancement of novel therapeutics that target neointimal hyperplasia, a characteristic of both pathologies. Gene therapy may provide a successful approach to improve the clinical outcome of these conditions, but would benefit from the development of more efficient vectors for vascular gene delivery. The aim of this study was to assess whether a novel genetically engineered Adenovirus could be utilised to produce enhanced levels of vascular gene expression.</p> <p>Methods: Vascular transduction capacity was assessed in primary human saphenous vein smooth muscle and endothelial cells using vectors expressing the LacZ reporter gene. The therapeutic capacity of the vectors was compared by measuring smooth muscle cell metabolic activity and migration following infection with vectors that over-express the candidate therapeutic gene tissue inhibitor of matrix metalloproteinase-3 (TIMP-3).</p> <p>Results: Compared to Adenovirus serotype 5 (Ad5), the novel vector Ad5T*F35++ demonstrated improved binding and transduction of human vascular cells. Ad5T*F35++ mediated expression of TIMP-3 reduced smooth muscle cell metabolic activity and migration in vitro. We also demonstrated that in human serum samples pre-existing neutralising antibodies to Ad5T*F35++ were less prevalent than Ad5 neutralising antibodies.</p> <p>Conclusions: We have developed a novel vector with improved vascular transduction and improved resistance to human serum neutralisation. This may provide a novel vector platform for human vascular gene transfer.</p&gt

A Spatiotemporal Notch Interaction Map From Plasma Membrane to Nucleus

Notch signaling relies on ligand-induced proteolysis of the transmembrane receptor Notch to liberate a nuclear effector that drives cell fate decisions. Upon ligand binding, sequential cleavage of Notch by the transmembrane protease ADAM10 and the intracellular protease γ-secretase releases the Notch intracellular domain (NICD), which translocates to the nucleus and forms a complex that induces target gene transcription. To map the location and timing of the individual steps required for the proteolysis and movement of Notch from the plasma membrane to the nucleus, we used proximity labeling with quantitative, multiplexed mass spectrometry to monitor the interaction partners of endogenous NOTCH2 after ligand stimulation in the presence of a γ-secretase inhibitor and as a function of time after inhibitor removal. Our studies showed that γ-secretase-mediated cleavage of NOTCH2 occurred in an intracellular compartment and that formation of nuclear complexes and recruitment of chromatin-modifying enzymes occurred within 45 min of inhibitor washout. These findings provide a detailed spatiotemporal map tracking the path of Notch from the plasma membrane to the nucleus and identify signaling events that are potential targets for modulating Notch activity

Health and healthcare of people with learning disabilities in the United Kingdom through the COVID-19 pandemic

Background During the COVID-19 pandemic in the United Kingdom, many health services were withdrawn from people with learning disabilities, with negative impacts on people's health. What has happened to people's health and healthcare as we move beyond the pandemic? Methods Access to health services and health status were tracked for 550 UK adults with learning disabilities, using structured online interviews with people with learning disabilities and online surveys with family members or paid carers. Information was provided four times, from Wave 1 (in the winter 2020/2021 ‘lockdown’) to Wave 4 (autumn 2022, over a year after public health protections stopped). Findings By Wave 4, most people with learning disabilities had had COVID-19, although high vaccination rates limited the number of people hospitalised. There was little evidence that use of GP services, community nurses, other therapists or annual health checks had increased over time, and at Wave 4 more people were having difficulty getting their medicines. People's health did not substantially improve over time. People with profound and multiple learning disabilities had poorer health and were less likely to be accessing health services. Conclusions Improvements in access to health services for people with learning disabilities after the pandemic have not yet happened

Pharmacologically directed strategies in academic anticancer drug discovery based on the European NCI compounds initiative

Background: The European NCI compounds programme, a joint initiative of the EORTC Research Branch, Cancer Research Campaign and the US National Cancer Institute, was initiated in 1993. The objective was to help the NCI in reducing the backlog of in vivo testing of potential anticancer compounds, synthesised in Europe that emerged from the NCI in vitro 60-cell screen. Methods: Over a period of more than twenty years the EORTC—Cancer Research Campaign panel reviewed ~2000 compounds of which 95 were selected for further evaluation. Selected compounds were stepwise developed with clear go/no go decision points using a pharmacologically directed programme. Results: This approach eliminated quickly compounds with unsuitable pharmacological properties. A few compounds went into Phase I clinical evaluation. The lessons learned and many of the principles outlined in the paper can easily be applied to current and future drug discovery and development programmes. Conclusions: Changes in the review panel, restrictions regarding numbers and types of compounds tested in the NCI in vitro screen and the appearance of targeted agents led to the discontinuation of the European NCI programme in 2017 and its transformation into an academic platform of excellence for anticancer drug discovery and development within the EORTC-PAMM group. This group remains open for advice and collaboration with interested parties in the field of cancer pharmacology
