Clearing the Air of Fog and Smog

The purpose of a readability formula is to produce a number or number range which approximates the achievement level required of a reader in order to comprehend a written passage. A useful formula, especially to the classroom teacher, is one which is easily computed and which accurately predicts the needed reading ability. Two formulas which have appeared in recent years, the Fog Index and the SMOG Grade, are easily applied. But are they accurate

Carers' experiences of accessing and navigating mental health care for older people in a rural area in Australia

Author accepted manuscript made available following 12 month embargo from date of publication (25 Aug 2015) in accordance with publisher copyright policy. “This is an Accepted Manuscript of an article published by Taylor & Francis in [Aging and Mental Health] on [25 Aug 2015], available online: http:// www.tandfonline.com/10.1080/13607863.2015.1078283”Objectives: Mental health care for older people is primarily delivered in the community and is largely dependent on informal carers. Mental health policy encourages partnerships between carers and service providers to facilitate service access, coordination and positive experience of care. However, carers often lack information and support from services, with the potential for carer burden, and negative impacts on their own health and capacity to fulfil caring tasks. This paper explores rural carers' experiences of accessing care from a range of services for older people with mental health problems. Method: The Pathways Interview Schedule was used to facilitate 9 in-depth care journey interviews with 11 carers of older people with a mental health problem. Interviews explored their journeys to and through mental health, aged care, primary care and social care services. Framework analysis was used to explore carers' experiences and perceptions of care with a focus on access enablers and barriers. Results: Carers had a significant role in navigating services and operationalising care for their relative. Enablers to accessing care included carer knowledge and workers actively involving carers in planning. Barriers included carer mental health literacy, consumer and carer readiness for services, and worker misinterpretation of confidentiality and privacy laws. Conclusion: Carers should be considered key partners in mental health care planning that crosses service sectors. For this to occur, changes are required at the worker level, including increased communication between mental health workers and carers, and the service level, involving training for staff in interpreting confidentiality and privacy policy

This article describes how older people’s mental health is governed through policy discourse by examining Australian Commonwealth and South Australian State government policy documents, and commentaries from professional groups, advocacy groups and non-governmental organisations. Documents published between 2009 and 2014 were analysed using a governmentality approach, informed by Foucault. Discourses of ‘risk’, ‘ageing as decline/dependence’ and ‘healthy ageing’ were identified. Through these discourses, different neo-liberal governmental strategies are applied to ‘target’ groups according to varying risk judgements. Three policy approaches were identified where older people are (1) absent from policy, (2) governed as responsible, active citizens or (3) governed as passive recipients of health care. This fragmented policy response to older people’s mental health reflects fragmentation in the Australian policy environment. It constructs an ambiguous place for older people within neo-liberal governmental rationality, with significant effects on the health system, older people and their carers

Xanthine oxidase inhibition for the improvement of long-term outcomes following ischaemic stroke and transient ischaemic attack (XILO-FIST) - Protocol for a randomised double blind placebo-controlled clinical trial

Background: Allopurinol, a xanthine oxidase inhibitor, reduced progression of carotid-intima media thickness and lowered blood pressure in a small clinical trial in people with ischaemic stroke. Xanthine oxidase inhibition for improvement of long-term outcomes following ischaemic stroke and transient ischaemic attack (XILO-FIST) aims to assess the effect of allopurinol treatment on white matter hyperintensity progression and blood pressure after stroke. This paper describes the XILO-FIST protocol. Methods: XILO-FIST is a multicentre randomised double-blind, placebo-controlled, parallel group clinical trial funded by the British Heart Foundation and the Stroke Association. The trial has been adopted by the Scottish Stroke Research Network and the UK Clinical Research Network. The trial is registered in clinicaltrials.gov (registration number NCT02122718). XILO-FIST will randomise 464 participants, aged greater than 50 years, with ischaemic stroke within the past month, on a 1:1 basis, to two years treatment with allopurinol 300 mg twice daily or placebo. Participants will undergo brain magnetic resonance imaging, cognitive assessment, ambulatory blood pressure monitoring and blood sampling at baseline and after two years treatment. The primary outcome will be white matter hyperintensity progression, measured using the Rotterdam progression scale. Secondary outcomes will include change in white matter hyperintensity volume, mean day-time systolic blood pressure and measures of cognitive function. Up to 100 will undergo additional cardiac magnetic resonance imaging in a sub-study of left ventricular mass. Discussion: If white matter hyperintensity progression is reduced, allopurinol could be an effective preventative treatment for patients with ischaemic stroke and clinical endpoint studies would be needed. If allopurinol reduces blood pressure after stroke, then it could be used to help patients reach blood pressure targets

Cerebellar plasticity and associative memories are controlled by perineuronal nets.

Perineuronal nets (PNNs) are assemblies of extracellular matrix molecules, which surround the cell body and dendrites of many types of neuron and regulate neural plasticity. PNNs are prominently expressed around neurons of the deep cerebellar nuclei (DCN), but their role in adult cerebellar plasticity and behavior is far from clear. Here we show that PNNs in the mouse DCN are diminished during eyeblink conditioning (EBC), a form of associative motor learning that depends on DCN plasticity. When memories are fully acquired, PNNs are restored. Enzymatic digestion of PNNs in the DCN improves EBC learning, but intact PNNs are necessary for memory retention. At the structural level, PNN removal induces significant synaptic rearrangements in vivo, resulting in increased inhibition of DCN baseline activity in awake behaving mice. Together, these results demonstrate that PNNs are critical players in the regulation of cerebellar circuitry and function

Hepatitis C – Assessment to Treatment Trial (HepCATT) in primary care:study protocol for a cluster randomised controlled trial

BACKGROUND: Public Health England (PHE) estimates that there are upwards of 160,000 individuals in England and Wales with chronic hepatitis C virus (HCV) infection, but until now only around 100,000 laboratory diagnoses have been reported to PHE and of these 28,000 have been treated. Targeted case-finding in primary care is estimated to be cost-effective; however, there has been no robust randomised controlled trial evidence available of specific interventions. Therefore, this study aims to develop and conduct a complex intervention within primary care and to evaluate this approach using a cluster randomised controlled trial. METHODS/DESIGN: A total of 46 general practices in South West England will be randomised in a 1:1 ratio to receive either a complex intervention comprising: educational training on HCV for the practice; poster and leaflet display in the practice waiting rooms to raise awareness and encourage opportunistic testing; a HCV risk prediction algorithm based on information on possible risk markers in the electronic patient record run using Audit + software (BMJ Informatica). The audit will then be used to recall and offer patients a HCV test. Control practices will follow usual care. The effectiveness of the intervention will be measured by comparing number and rates of HCV testing, the number and proportion of patients testing positive, onward referral, rates of specialist assessment and treatment in control and intervention practices. Intervention costs and health service utilisation will be recorded to estimate the NHS cost per new HCV diagnosis and new HCV patient initiating treatment. Longer-term cost-effectiveness of the intervention in improving quality-adjusted life years (QALYs) will be extrapolated using a pre-existing dynamic health economic model. Patients' and health care workers' experiences and acceptability of the intervention will be explored through semi-structured qualitative interviews. DISCUSSION: This trial has the potential to make an important impact on patient care and will provide high-quality evidence to help general practitioners make important decisions on HCV testing and onward referral. If found to be effective and cost-effective the intervention is readily scalable and can be used to support the implementation of NICE recommendations on HCV case-finding.

Effects of antiplatelet therapy on stroke risk by brain imaging features of intracerebral haemorrhage and cerebral small vessel diseases: subgroup analyses of the RESTART randomised, open-label trial

Background Findings from the RESTART trial suggest that starting antiplatelet therapy might reduce the risk of recurrent symptomatic intracerebral haemorrhage compared with avoiding antiplatelet therapy. Brain imaging features of intracerebral haemorrhage and cerebral small vessel diseases (such as cerebral microbleeds) are associated with greater risks of recurrent intracerebral haemorrhage. We did subgroup analyses of the RESTART trial to explore whether these brain imaging features modify the effects of antiplatelet therapy

How many human proteoforms are there?

Despite decades of accumulated knowledge about proteins and their post-translational modifications (PTMs), numerous questions remain regarding their molecular composition and biological function. One of the most fundamental queries is the extent to which the combinations of DNA-, RNA- and PTM-level variations explode the complexity of the human proteome. Here, we outline what we know from current databases and measurement strategies including mass spectrometry-based proteomics. In doing so, we examine prevailing notions about the number of modifications displayed on human proteins and how they combine to generate the protein diversity underlying health and disease. We frame central issues regarding determination of protein-level variation and PTMs, including some paradoxes present in the field today. We use this framework to assess existing data and to ask the question, "How many distinct primary structures of proteins (proteoforms) are created from the 20,300 human genes?" We also explore prospects for improving measurements to better regularize protein-level biology and efficiently associate PTMs to function and phenotype
