    Get PDF
    The decay of Escherichia coli in a sandy loam soil, amended with enhanced and conventionally treated biosolids, was investigated in a field experiment following spring and autumn applications of sewage sludge. Control soils, without the application of biosolids, were also examined to determine the background indigenous populations of E. coli which are present in the environment. The survival of indigenous E. coli and populations of E. coli applied to soil in biosolids, is assessed in relation to environmental factors influencing pathogen-decay processes in soil

    Aid alignment for global health research: the role of HIROs

    Get PDF
    The lack of a mechanism that aligns financial flows for global health research towards public health priorities limits the impact of health research on health and health equity. Collaborative groups of health research funders appear to be particularly well situated to ameliorate this situation and to initiate discussion on aid alignment for global health research. One such group is the Heads of International Research Organizations (HIROs), which brings together a large number of major government and philanthropic funders of biomedical research. Surprisingly, there is hardly any information publicly available on HIROs' objectives, or on how it aims to achieve more harmonization in the field of research for health. Greater transparency on HIROs' objectives and on its current efforts towards addressing the gap between global health research needs and investments would be desirable, given the enormous potential benefits of more coordination by this group

    Stakeholders' Participation in Planning and Priority Setting in the Context of a Decentralised Health Care system: the case of prevention of mother to child Transmission of HIV Programme in Tanzania.

    In Tanzania, decentralisation processes and reforms in the health sector aimed at improving planning and accountability in the sector. As a result, districts were given authority to undertake local planning and set priorities as well as allocate resources fairly to promote the health of a population with varied needs. Nevertheless, priority setting in the health care service has remained a challenge. The study assessed the priority setting processes in the planning of the prevention of mother to child transmission of HIV (PMTCT) programme at the district level in Tanzania. This qualitative study was conducted in Mbarali district, south-western Tanzania. The study applied in-depth interviews and focus group discussions in the data collection. Informants included members of the Council Health Management Team, regional PMTCT managers and health facility providers. Two plans were reported where PMTCT activities could be accommodated; the Comprehensive Council Health Plan and the Regional PMTCT Plan that was donor funded. As donors had their own globally defined priorities, it proved difficult for district and regional managers to accommodate locally defined PMTCT priorities in these plans. As a result few of these were funded. Guidelines and main priority areas of the Ministry of Health and Social Welfare (MoHSW) also impacted on the ability of the districts and regions to act, undermining the effectiveness of the decentralisation policy in the health sector. The challenges in the priority setting processes revealed within the PMTCT initiative indicate substantial weaknesses in implementing the Tanzania decentralisation policy. There is an urgent need to revive the strategies and aims of the decentralisation policy at all levels of the health care system with a view to improving health service delivery

    Low carbon innovation in China: from overlooked opportunities and challenges to transitions in power relations and practices

    Get PDF
    This paper explores environmental innovation in the largest emerging economy – China - and its potential for contributing to global transitions to low-carbon, more sustainable patterns of development. It builds on earlier studies bringing alternative forms of low(er)-technology, ‘below-the-radar’, ‘disruptive’ and/or social innovation into its analysis. In addition, however, the paper develops our understanding of low-carbon innovation by paying particular attention to issues of changing power relations and social practices; theoretical issues that need attention in the literature generally but are notably absent when studying transitions in China. This shift in perspective allows four neglected questions to be introduced and, in each case, points to both opportunities and challenges to low-carbon system transition that are overlooked by an orthodox focus on technological innovations alone. These are briefly illustrated by drawing on examples from three key domains of low-carbon innovation: solar-generated energy; electric urban mobility; and food and agriculture

    The utilisation of health research in policy-making: Concepts, examples and methods of assessment

    Get PDF
    The importance of health research utilisation in policy-making, and of understanding the mechanisms involved, is increasingly recognised. Recent reports calling for more resources to improve health in developing countries, and global pressures for accountability, draw greater attention to research-informed policy-making. Key utilisation issues have been described for at least twenty years, but the growing focus on health research systems creates additional dimensions. The utilisation of health research in policy-making should contribute to policies that may eventually lead to desired outcomes, including health gains. In this article, exploration of these issues is combined with a review of various forms of policy-making. When this is linked to analysis of different types of health research, it assists in building a comprehensive account of the diverse meanings of research utilisation. Previous studies report methods and conceptual frameworks that have been applied, if with varying degrees of success, to record utilisation in policy-making. These studies reveal various examples of research impact within a general picture of underutilisation. Factors potentially enhancing utilisation can be identified by exploration of: priority setting; activities of the health research system at the interface between research and policy-making; and the role of the recipients, or 'receptors', of health research. An interfaces and receptors model provides a framework for analysis. Recommendations about possible methods for assessing health research utilisation follow identification of the purposes of such assessments. Our conclusion is that research utilisation can be better understood, and enhanced, by developing assessment methods informed by conceptual analysis and review of previous studies

    Public health research systems in the European union

    <p>Abstract</p> <p>Background</p> <p>Strengthening health research is an important objective for international health organisations, but there has been less attention to support for health research in Europe. We describe the public-health (population and organisational level) research systems in the 27 European Union countries.</p> <p>Methods</p> <p>We developed a typology for describing health research structures based on funding streams and strategies. We drew data from internet sources and asked country informants to review these for consistency and completeness. The structures were described as organograms and narratives in country profiles for each of the 27 EU member states. National public-health research structures included public and independent funding organisations, 'mixed' institutions (which receive funds, and both use and allocate them) and provider institutions.</p> <p>Results</p> <p>Most health research is funded through ministries of science or science councils (and sometimes foundations), while parliaments and regions may also contribute. National institutes of public health are usually funded by ministries of health. Many national research organisations both determine research programmes and undertake health research, but there is a move towards public-health sciences within the universities, and a transition from internal grants to competitive funding. Of 27 national research strategies, 17 referred to health and 11 to public health themes. Although all countries had strategies for public health itself, we found little coherence in public-health research programmes. The European Commission has country contact points for both EU research and health programmes, but they do not coordinate with national health-research programmes.</p> <p>Conclusions</p> <p>Public-health research is broadly distributed across programmes in EU countries. Better understanding of research structures, programmes and results would improve recognition for public health in Europe, and contribute to practice. EU ministries of health should give greater attention to national public-health research strategies and programmes, and the European Union and the World Health Organisation can provide coordination and support.</p

    Improving care for people with dementia: development and initial feasibility study for evaluation of life story work in dementia care

    Get PDF
    Background: Improving dementia care quality is an urgent priority nationally and internationally. Life story work (LSW) is an intervention that aims to improve individual outcomes and care for people with dementia and their carers. LSW gathers information and artefacts about the person, their history and interests, and produces a tangible output: the ‘life story’. Objective: To establish whether or not full evaluation of LSW was feasible. Design: Mixed-methods feasibility study. Methods: In-depth interviews and focus groups explored experiences of LSW and best practice with people with dementia, family members and dementia care staff. A systematic review explored best practice and theories of change for LSW. These stages helped to identify the outcomes and resources to explore in the feasibility study. A representative sample survey of health and social care dementia care providers in England established LSW practice in different settings. A survey of a self-selected sample of family members of people with dementia explored how LSW is experienced. Two small outcome studies (stepped-wedge study in six care homes and pre-test post-test study in inpatient specialist dementia care wards) explored the feasibility of full evaluation of LSW in these settings. Settings: Survey: generalist and specialist care homes; NHS dementia care settings; and community dementia services. Feasibility study: care homes and NHS inpatient dementia care wards. Participants: NHS and social care services, people with dementia, family carers, care home staff and NHS staff. Interventions: LSW. Main outcome measures: Spread of LSW and good practice, quality of life (QoL) for the person with dementia and carers, relationships between people with dementia and family carers, staff attitudes about dementia, staff burnout, resource use and costs. Review methods: Narrative review and synthesis, following Centre for Review and Dissemination guidelines. Results: Good practice in LSW is identifiable, as are theories of change about how it might affect given outcomes. Indicators of best practice were produced. LSW is spreading but practice and use vary between care settings and are not always in line with identified good practice. Two different models of LSW are evident; these are likely to be appropriate at different stages of the dementia journey. The feasibility study showed some positive changes in staff attitudes towards dementia and, for some people with dementia, improvements in QoL. These may be attributable to LSW but these potential benefits require full evaluation. The feasibility work established the likely costs of LSW and highlighted the challenges of future evaluation in care homes and inpatient dementia care settings. Limitations: There was insufficient evidence in the literature to allow estimation of outcome size. We did not carry out planned Markov chain modelling to inform decisions about carrying out future evaluation because of the dearth of outcome data in the literature; low levels of data return for people with dementia in the hospital settings; lack of detected effect for most people with dementia; and questions about implementation in the research settings. Conclusions: LSW is used across different health and social care settings in England, but in different ways, not all of which reflect ‘good practice’. This large, complex study identified a wide range of challenges for future research, but also the possibility that LSW may help to improve care staff attitudes towards dementia and QoL for some people with dementia. Future work: Full evaluation of LSW as an intervention to improve staff attitudes and care is feasible with researchers based in or very close to care settings to ensure high-quality data collection.

    Antimicrobial peptides as novel anti-tuberculosis therapeutics

    Get PDF
    "Available online 24 May 2016"Tuberculosis (TB), a disease caused by the human pathogen Mycobacterium tuberculosis, has recently joined HIV/AIDS as the world's deadliest infectious disease, affecting around 9.6 million people worldwide in 2014. Of those, about 1.2 million died from the disease. Resistance acquisition to existing antibiotics, with the subsequent emergence of Multi-Drug Resistant mycobacteria strains, together with an increasing economic burden, has urged the development of new anti-TB drugs. In this scope, antimicrobial peptides (AMPs), which are small, cationic and amphipathic peptides that make part of the innate immune system, now arise as promising candidates for TB treatment. In this review, we analyze the potential of AMPs for this application. We address the mechanisms of action, advantages and disadvantages over conventional antibiotics and how problems associated with its use may be overcome to boost their therapeutic potential. Additionally, we address the challenges of translational development from benchside to bedside, evaluate the current development pipeline and analyze the expected global impact from a socio-economic standpoint. The quest for more efficient and more compliant anti-TB drugs, associated with the great therapeutic potential of emerging AMPs and the rising peptide market, provide an optimal environment for the emergence of AMPs as promising therapies. Still, their pharmacological properties need to be enhanced and manufacturing-associated issues need to be addressed.Portuguese Foundation for Science and Technology (FCT) - UID/ BIO/04469/2013 unit ; COMPETE 2020 (POCI-01-0145-FEDER- 006684) ; SFRH/BPD/64958/2010Project RECI/BBB-EBI/0179/2012 (FCOMP-01-0124-FEDER-027462
