en Review essay: Where is the Anthropocene? IR in a new geological epoch By feedproxy.google.com Published On :: Wed, 08 Jan 2020 13:46:10 +0000 8 January 2020 , Volume 96, Number 1 Read online Dahlia Simangan Several disciplines outside the natural sciences, including International Relations (IR), have engaged with the Anthropocene discourse in order to theorize their relevance and translate their practical value in this new phase of the Earth's history. Some IR scholars have called for a post-humanist IR, planet politics, a cosmopolitan view, and ecological security, among other approaches, to recalibrate the theoretical foundations of the discipline, making it more attuned to the realities of the Anthropocene. Existing discussions, however, tend to universalize human experience and gravitate towards western ontologies and epistemologies of living in the Anthropocene. Within this burgeoning scholarship, how is the IR discipline engaging with the Anthropocene discourse? Although the Anthropocene has become a new theoretical landscape for the conceptual broadening of conventional IR subjects, this review reveals the need for sustained discussion that highlights the differentiated human experiences in the Anthropocene. The existing IR publications on the Anthropocene locates the non-spatial narratives of vulnerability and historical injustice, the non-modernist understanding of nature, the agency of the vulnerable, and the amplification of security issues in the Anthropocene. It is in amplifying these narratives that the IR discipline can broaden and diversify the discourse on the Anthropocene and, therefore, affirm its relevance in this new geological age. Full Article

Policymakers can be influenced by ineffective carbon dioxide removal solutions in the quest to tackle climate change. This animation explores the risks of using bioenergy with carbon capture and storage (BECCS). SummaryCurrent climate efforts are not progressing quickly enough to prevent the world from overshooting the global emissions targets set in the Paris Agreement; accordingly, attention is turning increasingly to options for removing carbon dioxide from the atmosphere – ‘carbon dioxide removal’ (CDR). Alongside afforestation and reforestation, the main option under discussion is bioenergy with carbon capture and storage (BECCS): processes through which the carbon emissions from burning biomass for energy are captured before release into the atmosphere and stored in underground reservoirs.This pre-eminent status is not, however, based on a comprehensive analysis of the feasibility and impacts of BECCS. In reality, BECCS has many drawbacks.Models generally assume that biomass for energy is inherently carbon-neutral (and thus that BECCS, by capturing and storing the emissions from combustion, is carbon-negative), but in reality this is not a valid assumption.On top of this, the deployment of BECCS at the scales assumed in most models would consume land on a scale comparable to half that currently taken up by global cropland, entailing massive land-use change, potentially endangering food security and biodiversity. There is also significant doubt about the likely energy output of BECCS solutions.BECCS may still have some role to play in strategies for CDR, depending mainly on the feedstock used; but it should be evaluated on the same basis as other CDR options, such as nature-based solutions or direct air carbon capture and storage (DACCS). Analysis should take full account of carbon balances over time, the requirements of each CDR option in terms of demand for land, water and other inputs, and the consequences of that demand.There is an urgent need for policymakers to engage with these debates. The danger at the moment is that policymakers are ‘sleepwalking towards BECCS’ simply because most models incorporate it – or, almost as bad, it may be that they are simply ignoring the need for any meaningful action on CDR as a whole.

en What the European Green Deal Means for the UK By feedproxy.google.com Published On :: Wed, 26 Feb 2020 01:24:58 +0000 26 February 2020 Patrick Schröder Senior Research Fellow, Energy, Environment and Resources Programme @patricks_CH Google Scholar As a COP26 host, Britain’s climate policy is in the spotlight. It has three routes it can take in response to the latest climate policy developments of the EU. 2020-02-25-Leyen.jpg European Commission President Ursula von der Leyen unveils the European Green Deal in December 2019. Photo: Getty Images. In December 2019, the EU launched the European Green Deal, a comprehensive policy package which aims to make the continent carbon-neutral by 2050. It contains a wide range of legal and policy measures including support for restoring ecosystems and biodiversity, low-carbon mobility, and sustainable food systems and healthy diets.Even though the UK has now left the EU, and the UK government has made clear that there will be no regulatory alignment and no rule-taking from the EU, this will affect Britain’s markets, trade negotiations and stance in global climate action.The UK has essentially three choices in how to react. First, non-alignment, with low ambition for domestic climate and environmental policies and product standards; second, so-called dynamic alignment, which means non-regression on existing environmental regulations, with domestic UK policies mirroring those of the EU in the future; third, non-alignment but higher ambition, with a domestic policy agenda to emerge as global leader on climate and green industrial development.What would be the consequences of each of these three options? Non-alignmentThere is concern that the UK might be going down this route, swapping an established set of stringent EU environmental protections for a new set of deliberately loose regulations. For instance, standards on air pollution have been watered down in the new UK Environment Bill.As part of the European Green Deal, a carbon border adjustment tax to prevent ‘carbon leakage’ – companies relocating to countries with laxer climate policy outside the EU to avoid higher costs, with the result of increasing overall emissions – was also announced. The EU has already threatened to potentially apply this mechanism against the UK as part of its policy to ensure a ‘level playing field’ in trade between the two.Non-alignment on European carbon taxation and border adjustment would help to facilitate a quick trade deal with the US but it would clearly make it more difficult for UK businesses to sell into the EU market.Furthermore, the UK’s and the EU’s climate security concerns and interests continue to be closely tied together. Ignoring European climate policy developments might jeopardize the UK’s long-term climate security.Dynamic alignment and mirroring future standardsThis would be beneficial to the future industrial competitiveness of the UK’s manufacturing sector.The European Green Deal is more than a set of ambitious environmental policies. It also includes comprehensive plans for industrial policies, digitalization, financing mechanisms and investment programmes.A new Circular Economy Action Plan to be published in March 2020 (a leaked draft version is available) will introduce a set of new targets and regulations on a range of products. The aim is that ‘by 2030, only safer, circular and sustainable products should be placed on the EU market’.We can expect to see new eco-design requirements for information and communication technologies, and a revision of laws on hazardous substances in electrical and electronic equipment. The European Green Deal also aims to boost trade in secondary raw materials with regional initiatives aimed at ‘harmonizing national end-of-waste and by-product criteria’. Those could be a first step towards EU-wide criteria.Furthermore, the European Strategy for Data will facilitate the development of a ‘single market for data’ and develop electronic product passports which can improve the availability of information of products sold in the EU to tackle false green claims.The UK would benefit from mirroring these industrial policies domestically to achieve equivalence of standards. This could facilitate a closer partnership and would potentially also offer chances to UK businesses in the green technology sector to benefit not only in terms of EU market access, but also from the European Green Deal investment plan – a €1 trillion opportunity.Higher ambition: aiming for global leadershipThis gives the UK the unique opportunity to become a frontrunner. There are many challenges to implementing the European Green Deal, such as member states with little interest in green issues, which the UK can avoid.The new UK Environment Bill is the first example of a policy departure from EU regulations. While there are some elements that point to a loosening of standard, in statements accompanying the bill, the Department for Environment, Food and Rural Affairs has insisted that the UK will not be bound by future EU green rules and even ‘go beyond the EU’s level of ambition’ on the environment.For example, the bill introduces new charges for single-use plastic items to minimize their use and incentivize reusable alternatives. Plus, the UK aims to exceed the EU’s level of ambition to create global action by introducing powers to stop the exports of plastic waste to developing countries.Taking a global leadership role on climate would also benefit the UK's climate diplomacy to make this year’s COP 26 (jointly hosted with Italy) in Glasgow a success. The European Green Deal agenda sets a new benchmark for climate action and shows global leadership. If the UK also wants to be seen as leading the climate and sustainability agenda, it can scarcely afford to be seen as falling behind. Full Article
en Global aid and faith actors: the case for an actor-orientated approach to the ‘turn to religion’ By feedproxy.google.com Published On :: Wed, 04 Mar 2020 13:00:22 +0000 4 March 2020 , Volume 96, Number 2 Emma Tomalin Read Online In this article, drawing on the work of the development sociologist Norman Long, I make the case for an actor-oriented approach to understanding the ‘turn to religion’ by global aid actors over the past couple of decades. I ask, is the ‘turn to religion’ evidence of the emergence of post-secular partnerships or are faith actors being instrumentalized to serve neo-liberal development goals? I argue that neither option captures the whole story and advocate that the study of religion and development needs to move beyond a binary between the ‘turn to religion’ as either evidence of post-secular partnerships or of the ‘instrumentalization’ of religion by the secular global aid business, and instead to think about how faith actors themselves encounter and shape development discourses and frameworks, translate them into relevant formats and strategically employ them. Alongside the adoption of an actor-orientated approach, I build on the work of Lewis and Mosse, Olivier de Sardan and Bierschenk to view international faith-based organizations (IFBOs) as development brokers and translators. This approach allows me to articulate the distinctive role that many members of IFBOs report they play as intermediaries who shift register between the secular development language and the faith-inspired language of their local faith partners. I take the engagement of faith actors with the new Sustainable Development Goals framework as a case-study to explore this. Full Article
en Mapping the field of religious environmental politics By feedproxy.google.com Published On :: Wed, 04 Mar 2020 13:16:13 +0000 4 March 2020 , Volume 96, Number 2 Jeremy Kidwell Read Online Until fairly recently, consideration of religion has been marginal or even non-existent in the scholarly discourse about environmental politics. Renewed attention to the intersection of these fields has been encouraged by a recent widening in discussions of ‘environmental values’ to include the role of religious institutions and personal belief in forming spiritual environmental values and renewed attention to the place of ethics and religious institutions in global environmental politics. Following a range of historic declarations by religious leaders, the recent encyclical by Pope Francis signalled a new level of integration between Catholic concerns for social and environmental justice. Yet, much of the continued engagement by large environmental NGOs and governments has continued to ignore the complex interrelation of local, intermediate and transnational religious political ecology. In this article, which is based on data gathered during five years of fieldwork, primarily with British Christian REMOs (religious environmental movement organizations), I probe the complexities of political engagement with religious environmentalism which arise from the many different organizational iterations these groups may take. On the basis of such investigation I suggest that effective high-level engagement with REMO groups will be greatly enhanced by a nuanced understanding of the many different shapes that these groups can take, the various scales at which these groups organize, and the unique inflection that political action and group identity can take in a religious context.

en Acting Early, Saving Lives: Prevention and Promotion By feedproxy.google.com Published On :: Fri, 05 Jul 2019 09:25:01 +0000 Invitation Only Research Event 9 September 2019 - 9:00am to 5:00pm Chatham House | 10 St James's Square | London | SW1Y 4LE Universal Health Coverage (UHC) is driving the global health agenda and is embedded in the Sustainable Development Goals (SDGs). According to the World Health Organization, universal health coverage means that ‘all people and communities can use the promotive, preventive, curative, rehabilitative and palliative health services they need, of sufficient quality to be effective, while also ensuring that the use of these services does not expose the user to financial hardship’.Despite this comprehensive starting point, it has been observed that UHC efforts to date have focused more on provision of treatment services than promotion and prevention strategies. Not only is this a missed opportunity from a financing perspective (public health interventions often offer better value for money than curative services), without robust health promotion and prevention efforts, UHC may not fulfil its potential towards reducing health inequity.Primary health care (PHC) is a whole-of-society approach to health that aims to ensure the highest possible level of health and well-being and equitable distribution. PHC has been described as the cornerstone of UHC. As set out in the recent World Health Assembly report by the Director-General Primary health care towards universal health coverage: ‘..with its emphasis on promotion and prevention, addressing determinants and a people-centred approach, primary health care has proven to be a highly effective and efficient way to address the main causes of, and risk factors for, poor health...UHC and the health-related Sustainable Development Goals can only be sustainably achieved with a stronger emphasis on primary health care.’The 2018 Declaration of Astana has sparked a renewed commitment to PHC. For NCD and mental health advocates there is an opportunity to now build on the foundations of PHC, to deliver more equitable, people-centred and sustainable UHC.This event sets out why promotive and preventive health services for NCDs and mental health disorders are such an important part of UHC. It will focus on two key dimensions: the role of health promotion and preventative services within UHC in delivering health for all, and sustainable financing through innovative fiscal policy.As one of the first high level events looking exclusively at prevention in the context of UHC, it will serve as an important reference for those going forward into the High Level Meeting on UHC as well as a unique opportunity for participants from a range of perspectives to discuss the barriers to progress.The event is convened by Chatham House and the UK Working Group on NCDs – a coalition of over 20 UK-based NGOs with an interest in the inclusion of NCDs as an international development priority.ObjectivesTo understand how NCD prevention and mental health promotion are a key aspect of universal health coverage.To explore the case for investment in NCD prevention and mental health promotion, for both governments and donors/global health actors.To share experiences of financing and delivering prevention and promotion services, and to reflect on the potential of PHC to support NCD and mental health goals.Attendance at this event is by invitation only.

en England and Australia Are Failing in Their Commitments to Refugee Health By feedproxy.google.com Published On :: Mon, 09 Sep 2019 12:50:31 +0000 10 September 2019 Alexandra Squires McCarthy Former Programme Coordinator, Global Health Programme Robert Verrecchia Both boast of universal health care but are neglecting the most vulnerable. 2019-09-09-Manus.jpg A room where refugees were once housed on Manus Island, Papua New Guinea. Photo: Getty Images. England and Australia are considered standard-bearers of universal access to health services, with the former’s National Health Service (NHS) recognized as a global brand and the latter’s Medicare seen as a leader in the Asia-Pacific region. However, through the exclusion of migrant and refugee groups, each is failing to deliver true universality in their health services. These exclusions breach both their own national policies and of international commitments they have made.While the marginalization of mobile populations is not a new phenomenon, in recent years there has been a global increase in anti-migrant rhetoric, and such health care exclusions reflect a global trend in which undocumented migrants, refugees and asylum seekers are denied rights.They are also increasingly excluded in the interpretation of phrases such as ‘leave no one behind’ and ‘universal health coverage’, commonly used by UN bodies and member states, despite explicit language in UN declarations that commits countries to include mobile groups.Giving all people – including undocumented migrants and asylum seekers – access to health care is essential not just for the health of the migrant groups but also the public health of the populations that host them. In a world with almost one billion people on the move, failing to take account of such mobility leaves services ill-equipped and will result in missed early and preventative treatment, an increased burden on services and a susceptibility to the spread of infectious disease.EnglandWhile in the three other nations of the UK, the health services are accountable to the devolved government, the central UK government is responsible for the NHS in England, where there are considerably greater restrictions in access.Undocumented migrants and refused asylum seekers are entitled to access all health care services if doctors deem it clinically urgent or immediately necessary to provide it. However, the Home Office’s ‘hostile environment’ policies towards undocumented migrants, implemented aggressively and without training for clinical staff, are leading to the inappropriate denial of urgent and clearly necessary care.One example is the case of Elfreda Spencer, whose treatment for myeloma was delayed for one year, allowing the disease to progress, resulting in her death.In England, these policies, which closely link health care and immigration enforcement, are also deterring people from seeking health care they are entitled to. For example, medical bills received by migrants contain threats to inform immigration enforcement of their details if balances are not cleared in a certain timeframe. Of particular concern, the NGO Maternity Action has demonstrated that such a link to immigration officials results in the deterrence of pregnant women from seeking care during their pregnancy.Almost all leading medical organizations in the United Kingdom have raised concerns about these policies, highlighting the negative impact on public health and the lack of financial justification for their implementation. Many have highlighted that undocument migrants use just and estimated 0.3% of the NHS budget and have pointed to international evidence that suggests that restrictive health care policies may cost the system more.AustraliaIn Australia, all people who seek refuge by boat are held, and have their cases processed offshore in Papua New Guinea (PNG) and Nauru, at a cost of almost A$5 billion between 2013 and 2017. Through this international agreement, in place since 2013, Australia has committed to arrange and pay for the care for the refugees, including health services ‘to a standard of care broadly comparable to that available to the general Australian community under the public health system’.However, the standard of care made available to the refugees is far from comparable to that available to the general population in Australia. Findings against the current care provision contractor on PNG, Pacific International Hospital, which took over in the last year, are particularly damning.For instance, an Australian coroner investigating the 2014 death from a treatable leg infection of an asylum seeker held in PNG concluded that the contractor lacked ‘necessary clinical skills’, and provided ‘inadequate’ care. The coroner’s report, issued in 2018, found the company had also, in other cases, denied care, withheld pain relief, distributed expired medication and had generally poor standards of care, with broken or missing equipment and medication, and services often closed when they were supposed to be open.This has also been reiterated by the Royal Australasian College of Physicians, which has appealed to the Australian government to end its policies of offshore processing immediately, due to health implications for asylum seekers. This echoes concerns of the medical community around the government’s ongoing attempts to repeal the ‘Medivac’ legislation, which enables emergency medical evacuation from PNG and Nauru.Bad policyBoth governments have signed up to UN Sustainable Development Goals commitment to ‘safe and orderly migration’, an essential component of which is access to health care. The vision for this was laid out in a global action plan on promoting the health of refugees and migrants, agreed by member states at the 2019 World Health Assembly.However, rather than allow national policies to be informed by such international plans and the evidence put forward by leading health professionals and medical organizations, the unsubstantiated framing of migrants as a security risk and economic burden has curtailed migrant and refugee access to health care.The inclusion of migrants and refugees within universal access to health services is not merely a matter of human rights. Despite being framed as a financial burden, ensuring access for all people may reduce costs on health services through prevention of costly later-stage medical complications, increased transmission of infections and inefficient administrative costs of determining eligibility.Thailand provides an example of a middle-income country that recognized this, successfully including all migrants and refugees in its health reforms in 2002. Alongside entitling all residents to join the universal coverage scheme, the country also ensured that services were ‘migrant friendly’, including through the provision of translators. A key justification for the approach was the economic benefit of ensuring a healthy migrant population, including the undocumented population.The denial of quality health services to refugees and undocumented migrants is a poor policy choice. Governments may find it tempting to gain political capital through excluding these groups, but providing adequate access to health services is part of both governments’ commitments made at the national and international levels. Not only are inclusive health services feasible to implement and good for the health of migrants and refugees, in the long term, they are safer for public health and may save money. Full Article
en Strengthening National Accountability and Preparedness for Global Health Security (SNAP-GHS) By feedproxy.google.com Published On :: Thu, 19 Dec 2019 15:43:55 +0000 The project aims to identify the enablers and barriers to enhance data use by National Public Health Institutes (NPHIs), producing outputs that will facilitate strengthening of the role of NPHIs in monitoring potential public health threats, and in shaping and informing domestic policies on health security and preparedness. Global health security is underpinned by the actions taken at a national level to ensure capacities exist to sufficiently prepare for and respond to acute threats and crises. In many contexts, National Public Health Institutes (NPHIs) were first established because of, and in response to, specific public health challenges typically related to infectious diseases.The Strengthening National Accountability and Preparedness for Global Health Security (SNAP-GHS) project evolved from a series of roundtables and discussions hosted by the Centre on Global Health Security at Chatham House, in collaboration with the Graduate Institute of Geneva.The outcome of the project is a SNAP-GHS Toolkit to support NPHIs in better diagnosing and understanding the challenges to data use within their own institutes, as well as in relation to external stakeholders and agencies. The toolkit is intended to be used for further circulation and dissemination by the International Association of National Public Health Institutes (IANPHI).The project is led by the Centre on Global Health Security at Chatham House in collaboration with the Ethiopian Public Health Institute, the Nigeria Centre for Disease Control, and the National Institute for Health in Pakistan.

en Coronavirus: Public Health Emergency or Pandemic – Does Timing Matter? By feedproxy.google.com Published On :: Fri, 01 May 2020 14:48:43 +0000 1 May 2020 Dr Charles Clift Senior Consulting Fellow, Global Health Programme @CliftWorks The World Health Organization (WHO) has been criticized for delaying its announcements of a public health emergency and a pandemic for COVID-19. But could earlier action have influenced the course of events? 2020-05-01-Tedros-WHO-COVID WHO director-general Dr Tedros Adhanom Ghebreyesus at the COVID-19 press briefing on March 11, 2020, the day the coronavirus outbreak was classed as a pandemic. Photo by FABRICE COFFRINI/AFP via Getty Images. The World Health Organization (WHO) declared the spread of COVID-19 to be a Public Health Emergency of International Concern (PHEIC) on January 30 this year and then characterized it as a pandemic on March 11.Declaring a PHEIC is the highest level of alert that WHO is obliged to declare, and is meant to send a powerful signal to countries of the need for urgent action to combat the spread of the disease, mobilize resources to help low- and middle-income countries in this effort and fund research and development on needed treatments, vaccines and diagnostics. It also obligates countries to share information with WHO.Once the PHEIC was declared, the virus continued to spread globally, and WHO began to be asked why it had not yet declared the disease a pandemic. But there is no widely accepted definition of a pandemic, generally it is just considered an epidemic which affects many countries globally.Potentially more deadlyThe term has hitherto been applied almost exclusively to new forms of flu, such as H1N1 in 2009 or Spanish flu in 1918, where the lack of population immunity and absence of a vaccine or effective treatments makes the outbreak potentially much more deadly than seasonal flu (which, although global, is not considered a pandemic).For COVID-19, WHO seemed reluctant to declare a pandemic despite the evidence of global spread. Partly this was because of its influenza origins — WHO’s emergency programme executive director said on March 9 that ‘if this was influenza, we would have called a pandemic ages ago’.He also expressed concern that the word traditionally meant moving — once there was widespread transmission — from trying to contain the disease by testing, isolating the sick and tracing and quarantining their contacts, to a mitigation approach, implying ‘the disease will spread uncontrolled’.WHO’s worry was that the world’s reaction to the word pandemic might be there was now nothing to be done to stop its spread, and so countries would effectively give up trying. WHO wanted to send the message that, unlike flu, it could still be pushed back and the spread slowed down.In announcing the pandemic two days later, WHO’s director-general Dr Tedros Adhanom Ghebreyesus reemphasised this point: ‘We cannot say this loudly enough, or clearly enough, or often enough: all countries can still change the course of this pandemic’ and that WHO was deeply concerned ‘by the alarming levels of inaction’.The evidence suggests that the correct message did in fact get through. On March 13, US president Donald Trump declared a national emergency, referring in passing to WHO’s announcement. On March 12, the UK launched its own strategy to combat the disease. And in the week following WHO’s announcements, at least 16 other countries announced lockdowns of varying rigour including Austria, Belgium, Canada, Czech Republic, Denmark, Finland, France, Germany, Hungary, Netherlands, Norway, Poland, Portugal, Serbia, Spain and Switzerland. Italy and Greece had both already instituted lockdowns prior to the WHO pandemic announcement.It is not possible to say for sure that WHO’s announcement precipitated these measures because, by then, the evidence of the rapid spread was all around for governments to see. It may be that Italy’s dramatic nationwide lockdown on March 9 reverberated around European capitals and elsewhere.But it is difficult to believe the announcement did not have an effect in stimulating government actions, as was intended by Dr Tedros. Considering the speed with which the virus was spreading from late February, might an earlier pandemic announcement by WHO have stimulated earlier aggressive actions by governments?Declaring a global health emergency — when appropriate — is a key part of WHO’s role in administering the International Health Regulations (IHR). Significantly, negotiations on revisions to the IHR, which had been ongoing in a desultory fashion in WHO since 1995, were accelerated by the experience of the first serious coronavirus outbreak — SARS — in 2002-2003, leading to their final agreement in 2005.Under the IHR, WHO’s director-general decides whether to declare an emergency based on a set of criteria and on the advice of an emergency committee. IHR defines an emergency as an ‘extraordinary event that constitutes a public health risk through the international spread of disease and potentially requires a coordinated international response’.In the case of COVID-19, the committee first met on January 22-23 but were unable to reach consensus on a declaration. Following the director-general’s trip to meet President Xi Jinping in Beijing, the committee reconvened on January 30 and this time advised declaring a PHEIC.But admittedly, public recognition of what a PHEIC means is extremely low. Only six have ever been declared, with the first being the H1N1 flu outbreak which fizzled out quickly, despite possibly causing 280,000 deaths globally. During the H1N1 outbreak, WHO declared a PHEIC in April 2009 and then a pandemic in June, only to rescind both in August as the outbreak was judged to have transitioned to behave like a seasonal flu.WHO was criticized afterwards for prematurely declaring a PHEIC and overreacting. This then may have impacted the delay in declaring the Ebola outbreak in West Africa as a PHEIC in 2014, long after it became a major crisis. WHO’s former legal counsel has suggested the PHEIC — and other aspects of the IHR framework — may not be effective in stimulating appropriate actions by governments and needs to be reconsidered.When the time is right to evaluate lessons about the response, it might be appropriate to consider the relative effectiveness of the PHEIC and pandemic announcements and their optimal timing in stimulating appropriate action by governments. The effectiveness of lockdowns in reducing the overall death toll also needs investigation. Full Article
en Coronavirus Vaccine: Available For All, or When it's Your Turn? By feedproxy.google.com Published On :: Mon, 04 May 2020 15:39:19 +0000 4 May 2020 Professor David Salisbury CB Associate Fellow, Global Health Programme LinkedIn Despite high-level commitments and pledges to cooperate to ensure equitable global access to a coronavirus vaccine, prospects for fair distribution are uncertain. 2020-05-04-Vaccine-COVID-Brazil Researcher in Brazil working on virus replication in order to develop a vaccine against the coronavirus. Photo by DOUGLAS MAGNO/AFP via Getty Images. When the H1N1 influenza pandemic struck in 2009, some industrialized countries were well prepared. Many countries’ preparedness plans had focused on preparing for an influenza pandemic and based on earlier alerts over the H5N1 ‘bird flu’ virus, countries had made advanced purchase or ‘sleeping’ contracts for vaccine supplies that could be activated as soon as a pandemic was declared. Countries without contracts scrambled to get supplies after those that already had contracts received their vaccine.Following the 2009 pandemic, the European Union (EU) developed plans for joint-purchase vaccine contracts that any member state could join, guaranteeing the same price per dose for everyone. In 2009, low-income countries were unable to get the vaccine until manufacturers agreed to let 10 per cent of their production go to the World Health Organization (WHO).The situation for COVID-19 could be even worse. No country had a sleeping contract in place for a COVID-19 vaccine since nobody had anticipated that the next pandemic would be a coronavirus, not an influenza virus. With around 80 candidate vaccines reported to be in development, choosing the right one will be like playing roulette.These candidates will be whittled down as some will fail at an early stage of development and others will not get to scale-up for manufacturing. All of the world’s major vaccine pharmaceutical companies have said that they will divert resources to manufacture COVID-19 vaccines and, as long as they choose the right candidate for production, they have the expertise and the capacity to produce in huge quantities.From roulette to a horse raceOur game now changes from roulette to a horse race, as the probability of winning is a matter of odds not a random chance. Countries are now able to try to make contracts alone or in purchasing consortia with other states, and with one of the major companies or with multiple companies. This would be like betting on one of the favourites.For example, it has been reported that Oxford University has made an agreement with pharmaceutical company AstraZeneca, with a possibility of 100 million doses being available by the end of 2020. If the vaccine works and those doses materialize, and are all available for the UK, then the UK population requirements will be met in full, and the challenge becomes vaccinating everyone as quickly as possible.Even if half of the doses were reserved for the UK, all those in high-risk or occupational groups could be vaccinated rapidly. However, as each major manufacturer accepts more contracts, the quantity that each country will get diminishes and the time to vaccinate the at-risk population gets longer.At this point, it is not known how manufacturers will respond to requests for vaccine and how they will apportion supplies between different markets. You could bet on an outsider. You study the field and select a biotech that has potential with a good production development programme and a tie-in with a smaller-scale production facility.If other countries do not try to get contracts, you will get your vaccine as fast as manufacturing can be scaled up; but because it is a small manufacturer, your supplies may take a long time. And outsiders do not often win races. You can of course, depending on your resources, cover several runners and try to make multiple contracts. However, you take on the risk that some will fail, and you may have compromised your eventual supply.On April 24, the WHO co-hosted a meeting with the president of France, the president of the European Commission and the Bill & Melinda Gates Foundation. It brought together heads of state and industry leaders who committed to ‘work towards equitable global access based on an unprecedented level of partnership’. They agreed ‘to create a strong unified voice, to build on past experience and to be accountable to the world, to communities and to one another’ for vaccines, testing materials and treatments.They did not, however, say how this will be achieved and the absence of the United States was notable. The EU and its partners are hosting an international pledging conference on May 4 that aims to raise €7.5 billion in initial funding to kick-start global cooperation on vaccines. Co-hosts will be France, Germany, Italy, the United Kingdom, Norway and Saudi Arabia and the priorities will be ‘Test, Treat and Prevent’, with the latter dedicated to vaccines.Despite these expressions of altruism, every government will face the tension between wanting to protect their own populations as quickly as possible and knowing that this will disadvantage poorer countries, where health services are even less able to cope. It will not be a vote winner to offer a share in available vaccine to less-privileged countries.The factories for the biggest vaccine manufacturers are in Europe, the US and India. Will European manufacturers be obliged by the EU to restrict sales first to European countries? Will the US invoke its Defense Production Act and block vaccine exports until there are stocks enough for every American? And will vaccine only be available in India for those who can afford it?The lessons on vaccine availability from the 2009 influenza pandemic are clear: vaccine was not shared on anything like an equitable basis. It remains to be seen if we will do any better in 2020. Full Article
en Hepatic monoamine oxidase B is involved in endogenous geranylgeranoic acid synthesis in mammalian liver cells [Research Articles] By feedproxy.google.com Published On :: 2020-05-01T00:05:28-07:00 Geranylgeranoic acid (GGA) originally was identified in some animals and has been developed as an agent for preventing second primary hepatoma. We previously have also identified GGA as an acyclic diterpenoid in some medicinal herbs. Recently, we reported that in human hepatoma-derived HuH-7 cells, GGA is metabolically labeled from 13C-mevalonate. Several cell-free experiments have demonstrated that GGA is synthesized through geranylgeranial by oxygen-dependent oxidation of geranylgeraniol (GGOH), but the exact biochemical events giving rise to GGA in hepatoma cells remain unclear. Monoamine oxidase B (MOAB) has been suggested to be involved in GGOH oxidation. Here, using two human hepatoma cell lines, we investigated whether MAOB contributes to GGA biosynthesis. Using either HuH-7 cell lysates or recombinant human MAOB, we found that: 1) the MAO inhibitor tranylcypromine dose-dependently downregulates endogenous GGA levels in HuH-7 cells; and 2) siRNA-mediated MAOB silencing reduces intracellular GGA levels in HuH-7 and Hep3B cells. Unexpectedly, however, CRISPR/Cas9-generated MAOB-KO human hepatoma Hep3B cells had GGA levels similar to those in MAOB-WT cells. A sensitivity of GGA levels to siRNA-mediated MAOB downregulation was recovered when the MAOB-KO cells were transfected with a MAOB-expression plasmid, suggesting that MAOB is the enzyme primarily responsible for GGOH oxidation and that some other latent metabolic pathways may maintain endogenous GGA levels in the MAOB-KO hepatoma cells. Along with the previous findings, these results provide critical insights into the biological roles of human MAOB and provide evidence that hepatic MAOB is involved in endogenous GGA biosynthesis via GGOH oxidation.

en A novel GPER antagonist protects against the formation of estrogen-induced cholesterol gallstones in female mice [Research Articles] By feedproxy.google.com Published On :: 2020-05-01T00:05:27-07:00 Many clinical studies and epidemiological investigations have clearly demonstrated that women are twice as likely to develop cholesterol gallstones as men, and oral contraceptives and other estrogen therapies dramatically increase that risk. Further, animal studies have revealed that estrogen promotes cholesterol gallstone formation through the estrogen receptor (ER) α, but not ERβ, pathway. More importantly, some genetic and pathophysiological studies have found that G protein-coupled estrogen receptor (GPER) 1 is a new gallstone gene, Lith18, on chromosome 5 in mice and produces additional lithogenic actions, working independently of ERα, to markedly increase cholelithogenesis in female mice. Based on computational modeling of GPER, a novel series of GPER-selective antagonists were designed, synthesized, and subsequently assessed for their therapeutic effects via calcium mobilization, cAMP, and ERα and ERβ fluorescence polarization binding assays. From this series of compounds, one new compound, 2-cyclohexyl-4-isopropyl-N-(4-methoxybenzyl)aniline (CIMBA), exhibits superior antagonism and selectivity exclusively for GPER. Furthermore, CIMBA reduces the formation of 17β-estradiol-induced gallstones in a dose-dependent manner in ovariectomized mice fed a lithogenic diet for 8 weeks. At 32 μg/day/kg CIMBA, no gallstones are found, even in ovariectomized ERα (–/–) mice treated with 6 μg/day 17β-estradiol and fed the lithogenic diet for 8 weeks. In conclusion, CIMBA treatment protects against the formation of estrogen-induced cholesterol gallstones by inhibiting the GPER signaling pathway in female mice. CIMBA may thus be a new agent for effectively treating cholesterol gallstone disease in women. Full Article
en Vitamin E does not prevent Western diet-induced NASH progression and increases metabolic flux dysregulation in mice [Research Articles] By feedproxy.google.com Published On :: 2020-05-01T00:05:27-07:00 Fatty liver involves ectopic lipid accumulation and dysregulated hepatic oxidative metabolism, which can progress to a state of elevated inflammation and fibrosis referred to as nonalcoholic steatohepatitis (NASH). The factors that control progression from simple steatosis to NASH are not fully known. Here, we tested the hypothesis that dietary vitamin E (VitE) supplementation would prevent NASH progression and associated metabolic alterations induced by a Western diet (WD). Hyperphagic melanocortin-4 receptor-deficient (MC4R–/–) mice were fed chow, chow+VitE, WD, or WD+VitE starting at 8 or 20 weeks of age. All groups exhibited extensive hepatic steatosis by the end of the study (28 weeks of age). WD feeding exacerbated liver disease severity without inducing proportional changes in liver triglycerides. Eight weeks of WD accelerated liver pyruvate cycling, and 20 weeks of WD extensively upregulated liver glucose and oxidative metabolism assessed by 2H/13C flux analysis. VitE supplementation failed to reduce the histological features of NASH. Rather, WD+VitE increased the abundance and saturation of liver ceramides and accelerated metabolic flux dysregulation compared with 8 weeks of WD alone. In summary, VitE did not limit NASH pathogenesis in genetically obese mice, but instead increased some indicators of metabolic dysfunction. Full Article
en Myeloid-specific deficiency of pregnane X receptor decreases atherosclerosis in LDL receptor-deficient mice [Research Articles] By feedproxy.google.com Published On :: 2020-05-01T00:05:27-07:00 The pregnane X receptor (PXR) is a nuclear receptor that can be activated by numerous drugs and xenobiotic chemicals. PXR thereby functions as a xenobiotic sensor to coordinately regulate host responses to xenobiotics by transcriptionally regulating many genes involved in xenobiotic metabolism. We have previously reported that PXR has pro-atherogenic effects in animal models, but how PXR contributes to atherosclerosis development in different tissues or cell types remains elusive. In this study, we generated an LDL receptor-deficient mouse model with myeloid-specific PXR deficiency (PXRMyeLDLR–/–) to elucidate the role of macrophage PXR signaling in atherogenesis. The myeloid PXR deficiency did not affect metabolic phenotypes and plasma lipid profiles, but PXRMyeLDLR–/– mice had significantly decreased atherosclerosis at both aortic root and brachiocephalic arteries compared with control littermates. Interestingly, the PXR deletion did not affect macrophage adhesion and migration properties, but reduced lipid accumulation and foam cell formation in the macrophages. PXR deficiency also led to decreased expression of the scavenger receptor CD36 and impaired lipid uptake in macrophages of the PXRMyeLDLR–/– mice. Further, RNA-Seq analysis indicated that treatment with a prototypical PXR ligand affects the expression of many atherosclerosis-related genes in macrophages in vitro. These findings reveal a pivotal role of myeloid PXR signaling in atherosclerosis development and suggest that PXR may be a potential therapeutic target in atherosclerosis management. Full Article
en Lipid rafts and neurodegeneration: structural and functional roles in physiologic aging and neurodegenerative diseases [Thematic Reviews] By feedproxy.google.com Published On :: 2020-05-01T00:05:27-07:00 Lipid rafts are small, dynamic membrane areas characterized by the clustering of selected membrane lipids as the result of the spontaneous separation of glycolipids, sphingolipids, and cholesterol in a liquid-ordered phase. The exact dynamics underlying phase separation of membrane lipids in the complex biological membranes are still not fully understood. Nevertheless, alterations in the membrane lipid composition affect the lateral organization of molecules belonging to lipid rafts. Neural lipid rafts are found in brain cells, including neurons, astrocytes, and microglia, and are characterized by a high enrichment of specific lipids depending on the cell type. These lipid rafts seem to organize and determine the function of multiprotein complexes involved in several aspects of signal transduction, thus regulating the homeostasis of the brain. The progressive decline of brain performance along with physiological aging is at least in part associated with alterations in the composition and structure of neural lipid rafts. In addition, neurodegenerative conditions, such as lysosomal storage disorders, multiple sclerosis, and Parkinson’s, Huntington’s, and Alzheimer’s diseases, are frequently characterized by dysregulated lipid metabolism, which in turn affects the structure of lipid rafts. Several events underlying the pathogenesis of these diseases appear to depend on the altered composition of lipid rafts. Thus, the structure and function of lipid rafts play a central role in the pathogenesis of many common neurodegenerative diseases. Full Article
en Lipid rafts and pathogens: the art of deception and exploitation [Thematic Reviews] By feedproxy.google.com Published On :: 2020-05-01T00:05:27-07:00 Lipid rafts, solid regions of the plasma membrane enriched in cholesterol and glycosphingolipids, are essential parts of a cell. Functionally, lipid rafts present a platform that facilitates interaction of cells with the outside world. However, the unique properties of lipid rafts required to fulfill this function at the same time make them susceptible to exploitation by pathogens. Many steps of pathogen interaction with host cells, and sometimes all steps within the entire lifecycle of various pathogens, rely on host lipid rafts. Such steps as binding of pathogens to the host cells, invasion of intracellular parasites into the cell, the intracellular dwelling of parasites, microbial assembly and exit from the host cell, and microbe transfer from one cell to another all involve lipid rafts. Interaction also includes modification of lipid rafts in host cells, inflicted by pathogens from both inside and outside the cell, through contact or remotely, to advance pathogen replication, to utilize cellular resources, and/or to mitigate immune response. Here, we provide a systematic overview of how and why pathogens interact with and exploit host lipid rafts, as well as the consequences of this interaction for the host, locally and systemically, and for the microbe. We also raise the possibility of modulation of lipid rafts as a therapeutic approach against a variety of infectious agents. Full Article

en The short variant of optic atrophy 1 (OPA1) improves cell survival under oxidative stress [Bioenergetics] By feedproxy.google.com Published On :: 2020-05-08T03:41:14-07:00 Optic atrophy 1 (OPA1) is a dynamin protein that mediates mitochondrial fusion at the inner membrane. OPA1 is also necessary for maintaining the cristae and thus essential for supporting cellular energetics. OPA1 exists as membrane-anchored long form (L-OPA1) and short form (S-OPA1) that lacks the transmembrane region and is generated by cleavage of L-OPA1. Mitochondrial dysfunction and cellular stresses activate the inner membrane–associated zinc metallopeptidase OMA1 that cleaves L-OPA1, causing S-OPA1 accumulation. The prevailing notion has been that L-OPA1 is the functional form, whereas S-OPA1 is an inactive cleavage product in mammals, and that stress-induced OPA1 cleavage causes mitochondrial fragmentation and sensitizes cells to death. However, S-OPA1 contains all functional domains of dynamin proteins, suggesting that it has a physiological role. Indeed, we recently demonstrated that S-OPA1 can maintain cristae and energetics through its GTPase activity, despite lacking fusion activity. Here, applying oxidant insult that induces OPA1 cleavage, we show that cells unable to generate S-OPA1 are more sensitive to this stress under obligatory respiratory conditions, leading to necrotic death. These findings indicate that L-OPA1 and S-OPA1 differ in maintaining mitochondrial function. Mechanistically, we found that cells that exclusively express L-OPA1 generate more superoxide and are more sensitive to Ca2+-induced mitochondrial permeability transition, suggesting that S-OPA1, and not L-OPA1, protects against cellular stress. Importantly, silencing of OMA1 expression increased oxidant-induced cell death, indicating that stress-induced OPA1 cleavage supports cell survival. Our findings suggest that S-OPA1 generation by OPA1 cleavage is a survival mechanism in stressed cells. Full Article
en Long noncoding RNA pncRNA-D reduces cyclin D1 gene expression and arrests cell cycle through RNA m6A modification [RNA] By feedproxy.google.com Published On :: 2020-04-24T06:08:45-07:00 pncRNA-D is an irradiation-induced 602-nt long noncoding RNA transcribed from the promoter region of the cyclin D1 (CCND1) gene. CCND1 expression is predicted to be inhibited through an interplay between pncRNA-D and RNA-binding protein TLS/FUS. Because the pncRNA-D–TLS interaction is essential for pncRNA-D–stimulated CCND1 inhibition, here we studied the possible role of RNA modification in this interaction in HeLa cells. We found that osmotic stress induces pncRNA-D by recruiting RNA polymerase II to its promoter. pncRNA-D was highly m6A-methylated in control cells, but osmotic stress reduced the methylation and also arginine methylation of TLS in the nucleus. Knockdown of the m6A modification enzyme methyltransferase-like 3 (METTL3) prolonged the half-life of pncRNA-D, and among the known m6A recognition proteins, YTH domain-containing 1 (YTHDC1) was responsible for binding m6A of pncRNA-D. Knockdown of METTL3 or YTHDC1 also enhanced the interaction of pncRNA-D with TLS, and results from RNA pulldown assays implicated YTHDC1 in the inhibitory effect on the TLS–pncRNA-D interaction. CRISPR/Cas9-mediated deletion of candidate m6A site decreased the m6A level in pncRNA-D and altered its interaction with the RNA-binding proteins. Of note, a reduction in the m6A modification arrested the cell cycle at the G0/G1 phase, and pncRNA-D knockdown partially reversed this arrest. Moreover, pncRNA-D induction in HeLa cells significantly suppressed cell growth. Collectively, these findings suggest that m6A modification of the long noncoding RNA pncRNA-D plays a role in the regulation of CCND1 gene expression and cell cycle progression. Full Article
en The single CCA-adding enzyme of T. brucei has distinct functions in the cytosol and in mitochondria [RNA] By feedproxy.google.com Published On :: 2020-05-01T00:06:09-07:00 tRNAs universally carry a CCA nucleotide triplet at their 3'-ends. In eukaryotes, the CCA is added post-transcriptionally by the CCA-adding enzyme (CAE). The mitochondrion of the parasitic protozoan Trypanosoma brucei lacks tRNA genes and therefore imports all of its tRNAs from the cytosol. This has generated interest in the tRNA modifications and their distribution in this organism, including how CCA is added to tRNAs. Here, using a BLAST search for genes encoding putative CAE proteins in T. brucei, we identified a single ORF, Tb927.9.8780, as a potential candidate. Knockdown of this putative protein, termed TbCAE, resulted in the accumulation of truncated tRNAs, abolished translation, and inhibited both total and mitochondrial CCA-adding activities, indicating that TbCAE is located both in the cytosol and mitochondrion. However, mitochondrially localized tRNAs were much less affected by the TbCAE ablation than the other tRNAs. Complementation assays revealed that the N-terminal 10 amino acids of TbCAE are dispensable for its activity and mitochondrial localization and that deletion of 10 further amino acids abolishes both. A growth arrest caused by the TbCAE knockdown was rescued by the expression of the cytosolic isoform of yeast CAE, even though it was not imported into mitochondria. This finding indicated that the yeast enzyme complements the essential function of TbCAE by adding CCA to the primary tRNA transcripts. Of note, ablation of the mitochondrial TbCAE activity, which likely has a repair function, only marginally affected growth. Full Article
en It takes two (Las1 HEPN endoribonuclease domains) to cut RNA correctly [RNA] By feedproxy.google.com Published On :: 2020-05-01T00:06:09-07:00 The ribosome biogenesis factor Las1 is an essential endoribonuclease that is well-conserved across eukaryotes and a newly established member of the higher eukaryotes and prokaryotes nucleotide-binding (HEPN) domain-containing nuclease family. HEPN nucleases participate in diverse RNA cleavage pathways and share a short HEPN nuclease motif (RφXXXH) important for RNA cleavage. Most HEPN nucleases participate in stress-activated RNA cleavage pathways; Las1 plays a fundamental role in processing pre-rRNA. Underscoring the significance of Las1 function in the cell, mutations in the human LAS1L (LAS1-like) gene have been associated with neurological dysfunction. Two juxtaposed HEPN nuclease motifs create Las1's composite nuclease active site, but the roles of the individual HEPN motif residues are poorly defined. Here using a combination of in vivo experiments in Saccharomyces cerevisiae and in vitro assays, we show that both HEPN nuclease motifs are required for Las1 nuclease activity and fidelity. Through in-depth sequence analysis and systematic mutagenesis, we determined the consensus HEPN motif in the Las1 subfamily and uncovered its canonical and specialized elements. Using reconstituted Las1 HEPN-HEPN' chimeras, we defined the molecular requirements for RNA cleavage. Intriguingly, both copies of the Las1 HEPN motif were important for nuclease function, revealing that both HEPN motifs participate in coordinating the RNA within the Las1 active site. We also established that conformational flexibility of the two HEPN domains is important for proper nuclease function. The results of our work reveal critical information about how dual HEPN domains come together to drive Las1-mediated RNA cleavage. Full Article
en Chemical roadblocking of DNA transcription for nascent RNA display [RNA] By feedproxy.google.com Published On :: 2020-05-08T03:41:14-07:00 Site-specific arrest of RNA polymerases (RNAPs) is fundamental to several technologies that assess RNA structure and function. Current in vitro transcription “roadblocking” approaches inhibit transcription elongation by blocking RNAP with a protein bound to the DNA template. One limitation of protein-mediated transcription roadblocking is that it requires inclusion of a protein factor extrinsic to the minimal in vitro transcription reaction. In this work, we developed a chemical approach for halting transcription by Escherichia coli RNAP. We first established a sequence-independent method for site-specific incorporation of chemical lesions into dsDNA templates by sequential PCR and translesion synthesis. We then show that interrupting the transcribed DNA strand with an internal desthiobiotin-triethylene glycol modification or 1,N6-etheno-2'-deoxyadenosine base efficiently and stably halts Escherichia coli RNAP transcription. By encoding an intrinsic stall site within the template DNA, our chemical transcription roadblocking approach enables display of nascent RNA molecules from RNAP in a minimal in vitro transcription reaction.

en RNA helicase-regulated processing of the Synechocystis rimO-crhR operon results in differential cistron expression and accumulation of two sRNAs [Gene Regulation] By feedproxy.google.com Published On :: 2020-05-08T03:41:14-07:00 The arrangement of functionally-related genes in operons is a fundamental element of how genetic information is organized in prokaryotes. This organization ensures coordinated gene expression by co-transcription. Often, however, alternative genetic responses to specific stress conditions demand the discoordination of operon expression. During cold temperature stress, accumulation of the gene encoding the sole Asp–Glu–Ala–Asp (DEAD)-box RNA helicase in Synechocystis sp. PCC 6803, crhR (slr0083), increases 15-fold. Here, we show that crhR is expressed from a dicistronic operon with the methylthiotransferase rimO/miaB (slr0082) gene, followed by rapid processing of the operon transcript into two monocistronic mRNAs. This cleavage event is required for and results in destabilization of the rimO transcript. Results from secondary structure modeling and analysis of RNase E cleavage of the rimO–crhR transcript in vitro suggested that CrhR plays a role in enhancing the rate of the processing in an auto-regulatory manner. Moreover, two putative small RNAs are generated from additional processing, degradation, or both of the rimO transcript. These results suggest a role for the bacterial RNA helicase CrhR in RNase E-dependent mRNA processing in Synechocystis and expand the known range of organisms possessing small RNAs derived from processing of mRNA transcripts.
