Fostering inclusive health systems amidst geopolitical instability 13 October 2024 — 9:00AM TO 10:00AM Anonymous (not verified) 11 September 2024 Sheraton Berlin Grand Hotel Esplanade

How can we build trust and inclusivity in the health sector in a fractured geopolitical environment?

Building trust in government, service provision and delivery are crucial considerations for policymakers who aim to make local, national and international health systems more inclusive. In the health space, trust can be a matter of life and death. Understanding and modulating policies that account for the trust factor, alongside the geopolitical determinants of health, can lead to more inclusive decision making and thus better health outcomes for larger proportions of a population.

International unity is key to addressing the challenges posed by geopolitical instability, which include disinformation campaigns, rising nationalism and growing divisions between states. If countries can find common ground through an inclusive approach to health, the effects could be transformative in achieving global health and equity targets.

This discussion, held in partnership with Haleon, will examine what it takes to foster trust and resilience in the health sector, achieve global inclusivity aims and chart a path for the public and private spheres to come together to navigate a fractured geopolitical environment.

• In what ways can localised health inclusivity data help policymakers to alleviate gaps in healthcare provision and why is this an essential element in instilling trust across the system?
• What role should multilateral organizations play in setting precedents for health inclusivity around the world?
• How do health inclusivity policies empower the service user and help reduce the burden placed on public healthcare systems?
• How can the health sector come together to ensure individuals are included within their own health decisions, are able to access services regardless of demographics and geography and trust their healthcare providers?

This event will be held at the Sheraton Hotel, Grand Esplanade, Berlin in the margins of the World Health Summit. You do not need a ticket for the World Health Summit to attend this event.

In their comment (1) on our publication (2), the authors make two points: (i) they raise concerns about the possible effect of residual NONOate in our study, and (ii) they promote nitrosylcobalamin (NOCbl) supplied by their own company. Both points lack merit for the following reasons. The authors make the astonishing claim that the spectra of nitric oxide (NO•) and cobalamins overlap. Unlike NO•, cobalamin absorbs in the visible region, permitting unequivocal spectral assignment of NOCbl as reported (3). We demonstrated that whereas NOCbl is highly unstable in solution, it is stabilized by the B12 trafficking protein CblC. So even if present, residual NONOate (which is unstable at neutral pH and is removed during the work-up (3)) could not account for the observed difference.The authors then misrepresent our synthetic method, claiming that anaerobic conditions were used to generate nitrocobalamin (NO2Cbl), which results in the transient formation of NOCbl. We synthesized NO2Cbl aerobically using nitrite as described (4); NOCbl is not an intermediate in this ligand exchange reaction. The aerobic instability of NOCbl has been rigorously described by inorganic chemists (3, 5) and raises obvious questions about its purported biological effects as exemplified by the authors' own 2003 JBC publication, which was later withdrawn.As to promoting NOCbl from their company, the authors refer to a synthetic route from a mixture of NO• gas and aquocobalamin. The authors' method (6) has been described as “dubious” by chemists (5). Whereas DEAE NONOate used in our method is widely known as an NO• donor,...

After a thorough read of this paper (1), we wish to clarify that the authors' anaerobic method of synthesis for the production of nitrocobalamin results in the transient formation of nitrosylcobalamin, an unstable intermediate upon exposure to air. We concur that the authors' method results in the production of nitrocobalamin based on the UV-visible data as shown. The authors' adapted anaerobic method consists of mixing hydroxocobalamin hydrochloride with diethylamine NONOate diethylammonium salt in aqueous solution. Of concern, the UV spectrum of nitric oxide overlaps that of all cobalamin species under anaerobic conditions, making any assignments of the binding of nitric oxide to hydroxocobalamin suspect (2). Additionally, the use of acetone to precipitate the authors' product causes precipitation of diethylamine NONOate, resulting in an impure product. As a result, its utility for drawing experimental conclusions is faulty.The product from the authors' anaerobic synthetic method has not been assessed for purity, and the synthetic method itself has not been validated using a stability-indicating method as required by the International Conference on Harmonization (ICH) (ICH Q2B, Validation of Analytical Procedures) methodology, which is a hallmark for analytical characterization. Our nitrosylcobalamin synthesis involves reacting nitric oxide gas with hydroxocobalamin acetate as a heterogeneous mixture in a non-electron-donating solvent followed by rotary evaporation. Our nitrosylcobalamin product is stable in air, releases nitric oxide gas in situ (3), and meets ICH stability guidelines (4). Additionally, our nitrosylcobalamin product demonstrates biological activity, which has not been observed for nitrocobalamin (3, 5).

America’s vote shows a desire for stability and calm Expert comment NCapeling 11 November 2022

Joe Biden has presided over the best midterm election results by a party in power in two decades, but the future for the Republican Party leadership is now uncertain.

For a president continually struggling with low approval ratings, the midterms provided a stunning result as the widely anticipated Republican red wave failed to materialize.

Although Democrats look set to lose their majority in the House, it is by a much smaller margin than either history or today’s pollsters anticipated. Democrats have maintained their majority in the Senate, a result that was confirmed four days after election day when Senator Catherine Cortez Masto won reelection. The final Senate seat will be decided by a 6 December run-off in the state of Georgia. 

The midterm elections were not good for the Republican party but were especially bad for Donald Trump who has until now managed to defy expectations and maintain his grip on the party even after his 2020 defeat at the polls.

Trump managed to win the presidency once but he lost the popular vote twice and at no stage during his time in office did his approval ratings go above 40 per cent. Now, after six years of the most divisive and disruptive leadership the US has ever seen, he has presided over the worst midterm results a party out of power has suffered in two decades.

Trump’s influence is on the wane

Many of the candidates endorsed by the former president – including in battleground states such as Pennsylvania and Arizona – lost. In Georgia, the Republican governor and Trump GOP rival won, despite Trump’s opposition, and the candidate he endorsed for the US Senate has come up short of the 50 per cent needed to get over the line in the first round.

Trump’s nemesis, Ron DeSantis, the Republican governor of Florida, won a second four-year term in a landslide. Trump is suffering attacks from his own party and many loyal media supporters, such as Fox News, the New York Post, and the Wall Street Journal. None of this bodes well for the prospect of Trump leading the party through the 2024 presidential election.

After six years of chaos, this upset has been delivered with remarkably little chaos and, so far, no violence in a win for democracy and stability in the US which will reverberate beyond the US shores.

The system has worked, with multiple elections held across all 50 states. Hotly contested seats were decided peacefully even when the margins were thin. The midterm elections were also a win for democracy. In every battleground state, election deniers that were nominated to run for offices that would control state election systems, including in the 2024 presidential elections, have been defeated.

For a country with a polarized electorate and a radical Republican leader who has continued to spread disinformation and sought to rile his base, this election has been surprisingly normal.

This means the debate about the future of America’s international leadership is postponed. Biden is still in the saddle and, instead of a battle for control inside the Democratic party, it is the Republicans who look set to descend into internal conflict and recrimination.

The unofficial contest to win the Republican nomination for president has already begun. Donald Trump has signalled loudly that he plans to run. If he does, it could impact Republican prospects in the 6 December runoff for the final seat in the Senate. DeSantis may also run and could be followed by several aspiring Republican candidates. A disrupted party facing a period of significant change seems likely. 

Inflation and the economy proved key factors

As always, foreign policy barely featured in the elections but the result promises a period of continuity. Instead of facing dangerous sniping on Ukraine from an emboldened Republican House leadership, the Biden administration looks set to hold to its Ukraine policy.

Biden’s increasingly hard-line policy on China will continue to be qualified by a clear-headed determination – however hard – to cooperate on climate. Trade policy will remain stuck, as will US policy in the developing world.

Exit polls show Democrats were motivated to vote by the reversal of Roe vs Wade and the restrictions on abortion rights that followed, while Republicans voted against inflation.

But Democrats at the national level continually failed to effectively communicate the positive impacts of Biden’s legislative agenda for ordinary Americans, or to deliver a clear economic message.

The national leadership veered from abortion rights to the Inflation Reduction Act, to the future of democracy in the US – all of which proved too complicated to cut through.

The state level shows a more complex picture because inflation and the economy – which could have swept Republicans to victory – were blunted by dogged local campaigning from Democrats who knew their voters and spoke to the cost-of-living concerns which were top of their minds.

Nuclear stability for all put at risk by Putin's speech Explainer NCapeling 22 February 2023

Explaining the risks of Russia’s decision to suspend the New START nuclear treaty with the US, and the wider implications for international relations.

Why is New START important?

Following the collapse of the Intermediate-range Nuclear Forces treaty (INF), New START is the only remaining nuclear arms control treaty between the US and Russia.

This means that without it there would be no limits on numbers or the type of Russian and US deployed nuclear warheads. The limits set under New START are lower than those set under its predecessor, the Strategic Arms Reduction Treaty (START).

It is also important for maintaining some form of strategic arms control between Russia and the US. The treaty provides the US and Russia with mechanisms for transparency and confidence-building, for instance through regular biannual data exchanges, as well as measures for verification.

What is Russia able to do next after suspending participation?

President Vladimir Putin’s decision to suspend its participation could pave the way for Russia to increase the number of deployed warheads, delivery vehicles and launchers, potentially exceeding the limits placed on numbers under the new START.

Putin stated he would resume testing of nuclear weapons if the US resumed – Russia is a full state party to the nuclear Comprehensive Test Ban Treaty (CTBT) negotiated in 1996, as is the UK and France. The US has signed, as has China, but neither state has yet ratified the treaty.

Other countries required to ratify the treaty for it to enter into force include Egypt, India, Iran, Israel, North Korea, and Pakistan.

Although the US is modernizing its nuclear weapons forces, there is no need – or plan – for the US to test nuclear warheads, and it is the same for the UK and France.

Concerns are now rising that Russia could point to no-fissionable yield experiments – which are allowed under the treaty and which the US and other nuclear weapons possessors conduct primarily for safety purposes – and then falsely declare those to be nuclear weapons tests, thus paving the way for a narrative to justify the resumption of nuclear testing by Russia.

Conducting a nuclear weapons test would be seen clearly as a further step on the escalation scale towards nuclear use for Russia.

While inspections of nuclear weapons sites had not resumed since COVID-19, Russia’s suspension of its participation could result in the further halting of other transparency and verification measures under New START, including the regular mutual data exchanges between the US and Russia – for example on warhead numbers, locations, and technical information on weapons systems and their sites – which are conducted through the Bilateral Consultative Commission (BCC).

What is the difference between withdrawing from New START and ‘suspending’ participation?

In his speech, Putin announced the suspension of Russian participation in New START. While this does not mean Russia has formally withdrawn from the treaty, the suspension could enable Russia to continue preventing the US from inspecting its nuclear weapons sites and halt Russia’s participation in other obligations, such as the routine reporting and data exchanges on nuclear weapons as well as meetings of the BCC.

The decision to suspend participation rather than withdraw from the treaty means Russia retains the option to return to compliance at a later point. However, it is not yet clear under what conditions Russia would opt to return to compliance with the treaty, or whether this means the US will, in turn, suspend their own obligations.

The treaty text itself does not provide for a suspension of participation by parties to the treaty. However, the Vienna Convention on the Law of Treaties does address the mechanisms for suspension of participation in a treaty. Russia is a full state party to the Vienna Convention, but the US has remained a signatory without ratification since 1970.

There is a precedent of Russia suspending its membership in arms control treaties rather than withdrawing, which is when Russia suspended its participation in the original Treaty on Conventional Armed Forces in Europe (CFE) in 2007.

The US does not recognize Russia’s suspension of its participation in the CFE treaty, but this does not make a material difference to Russian actions.

What does the suspension mean for the wider international treaty regime?

Russia’s suspension of the New START could signal the end of strategic arms control between the two countries. There is now virtually no regular scheduled arms control communication between the two countries bilaterally – this is a dangerous position to be in, especially in times of crisis.

The suspension of New START further erodes limited recourse for communication between the two countries, by suspending information exchange and meetings of the BCC under the treaty.

This is likely to have wider implications for progress on nuclear non-proliferation under the Treaty on the Non-Proliferation of Nuclear Weapons (NPT), as well as the wider international security treaty regime.

Will this increase the nuclear threat or the likelihood of nuclear use?

New START provides both the US and Russia with a degree of transparency surrounding nuclear weapons systems. Without an avenue for regular data exchange and notification, and mechanisms for verification through mutual nuclear weapons site inspections, the risk of misperception or misunderstanding could increase and fuel uncertainty which could increases the perception of threat between Russia and the US.

What are Putin’s reasons for suspending Russia’s participation?

Putin and various members of his government have been linking the future of New START to the war in Ukraine rhetorically for several months now, threatening that Russia may not be willing to negotiate a follow-on treaty for when New START expires in Feb 2026 because of US support for Ukraine.

By announcing Russia’s suspension of the treaty in his main address on the anniversary of the invasion of Ukraine, Putin is sending a signal about Russia’s intent for the future.

Russia’s new hypersonic glide vehicle Avangard was already counted under New START and it is likely follow-on negotiations would have focused on some of Russia’s other hypersonic capabilities or other new nuclear systems.

Without the treaty, Russia might be less inhibited in its development of new nuclear systems.

Have both the US and Russia been compliant with the treaty until now?

Both the US and Russia have remained within the central limits of the treaty since its entry into force in 2011. Following the outbreak of COVID-19, both sides agreed to suspend in-person inspections due to restrictions on travel, and attempts to recommence in-person inspections in 2022 were unsuccessful.

In August 2022, Russia prevented US on-site inspections under New START and a November 2022 meeting of the BCC was called off by Russian officials. Russia has blamed both the ongoing COVID-19 pandemic and the sanctions burden on Russia as reasons for not wanting to resume inspections.

SVB collapse shows interest rate financial stability threat Expert comment LJefferson 15 March 2023

Governments must resist pressure to relax post-financial crisis regulation, while central banks should moderate their attack on inflation if financial stability is at risk.

The collapse of California’s Silicon Valley Bank (SVB) on 10 March has triggered a wave of volatility in global bank equity prices, raised questions about whether US bank regulation and its tech industry funding model are fit for purpose, and forced a rethink on the extent and pace of monetary policy tightening appropriate for the US and other advanced economies.

SVB was the US’s 16th largest bank with total assets of $212bn at the end of 2022 and a presence in eight countries around the world, including the UK. Since it was founded 40 years ago, it has maintained a strong focus on the technology sector, claiming recently that nearly half of all US venture-backed technology and life science companies banked with it. Partly as a consequence, some 95 per cent of its deposits came from corporates and hedge funds, far higher than the one-third typical of similarly sized banks.

What led to SVB’s collapse?

Ironically, SVB’s failure did not result from its core business model of serving a relatively high-risk and fast-growing sector, but rather from a dramatic failure in liquidity management. During the pandemic, SVB saw a very large inflow of corporate deposits. But rather than disincentivizing depositors or investing the funds attracted in assets of matching maturity, it chose to invest them in low credit risk, but long maturity bonds attracted by a small pick-up in return over shorter-term assets. 

When US interest rates began to rise rapidly in 2022 following Russia’s invasion of Ukraine, the value of SVB’s long-term bond portfolio declined sharply. It was left facing a large capital loss of some $15bn, roughly equivalent to its total shareholder funds. The management attempted to repair SVB’s balance sheet last week by crystalizing some of the loss and raising new capital.

But when this failed, the US supervisory authorities had no choice but to step in and close the institution.  This action was quickly followed by emergency action from other regulators vis-a-vis SVB subsidiaries and offices around the world.

The US entity has formally been taken over by the FDIC and a bridge bank established. All depositors have had their funds guaranteed, going beyond the normal federal deposit insurance limit of $250,000 per customer. However, bond holders and equity holders have been wiped out. The authorities have said that any loss will be covered by the industry as a whole via the FDIC.

In the UK, the Bank of England was able to sell the ring-fenced UK subsidiary of SVB to HSBC for £1 over the weekend, so that all its depositors and other liability holders have effectively had their funds guaranteed. In contrast to previous Bank of England rescues (such as Johnson Matthey Bank in 1984, the ‘small banks’ crisis in 1991 and the global financial crisis in 2008-9) no public money has been put at risk.

Four key questions

SVB’s rapid collapse raises four central questions:

First, how was it that the bank was able to take on such a risky interest rate maturity mismatch in its US operations? Maturity transformation is standard banking industry practice, but it is usually closely monitored by regulators who place limits on the extent of interest rate maturity mismatch and require liquidity buffers to offset the risk of deposit flight and forced asset sales.

SVB’s very high concentration of corporate deposits as compared to ‘sticky’ retail deposits, means that the risk of deposit flight was unusually high and so the bank should have been more, not less, cautious in its liquidity policy. SVB was classed as a regional bank in the US which means that it did not have to meet international regulatory standards under Basle III. And in 2018, the Trump administration approved legislation removing the post-financial crisis requirement that banks with assets under $250bn submit to stress testing and relaxing liquidity buffer requirements.

But it is still hard to understand why regulators allowed SVB to commit such a classic banking error. On Monday, the Federal Reserve ordered an inquiry into what it has correctly described as a regulatory failure. This should look at the role played by all the elements of the oversight system including the auditors, KPMG.

Second, does SVB’s failure reflect a much bigger underlying risk in the US banking sector, and potentially other banking systems around the world, built up over the prolonged period of ultra-low interest rates? SVB’s collapse was followed by the failure of the $110bn Signature Bank in New York, as well as sharp falls in US regional bank stock prices – by close of play on 14 March, the S&P Regional Bank Index was down 22 per cent on a week before, with some individual bank stocks seeing much sharper falls.  

To the extent that banks have been covered by international bank regulatory requirements, the risk of a much broader problem should be limited because stress testing and other regulatory tests would have looked at precisely the scenario that has happened. Even where large market losses have been incurred, capital buffers should be sufficient to cover them. But as SVB has shown, there are some large banks that are seemingly not required to follow international rules, while the latest developments at Credit Suisse indicate that market concerns may still arise when other factors are in play.

Third, how far, in the light of the potential vulnerability in banking systems, should central banks in advanced countries moderate their efforts to squeeze out inflationary pressures? While inflation already appears to have peaked in many economies and the pace of interest rate rises was expected to slow, inflation is far from vanquished, as recent data in the US has demonstrated.

Fourth, does the failure of SVB tell us something new about the financial risks facing the high technology sector?  It was remarkable that a single (and not particularly large, by international standards) financial institution could have played such a central role in the tech sector in both the US and UK. 

Why was this the case and does it reflect special features of the tech/start-up sector (e.g. the need for substantial cash deposits to cover relatively large negative cash flows in the early years of operation, or the need for highly specialized lending expertise). If so, should governments take steps to mitigate such risks, given the outsized importance of this sector in many national economic strategies?

Time to accelerate the sustainability pivot Expert comment NCapeling 26 May 2021

Higher stakes make it more important than ever to safeguard the integrity of sustainability commitments, and ensure high quality in delivery and implementation.

Regular headlines reaffirm the rise of sustainability on the global stage. Political momentum behind climate action has not been derailed by COVID-19, sustainability is increasingly central to national political debates, and what once might have been confined to scientific pursuits and UN conferences has now percolated through to international financial affairs and the wider political summits.

Much is made of the scale of the challenge, from climate change, water stresses, and biodiversity loss to the looming spectre of environment-induced societal breakdown triggering unprecedented civilizational challenges on the back of decades of systemic neglect over the true cost of social and environmental imbalances and unencumbered consumption.

But the good news is that talk of sustainability solutions is picking up pace and growing in its reach into the mainstream. The Wall Street Journal recently charted the shift of sustainable finance from being a niche interest of socially conscious investors into a sustainable ‘gold rush’, further bolstering its financial credentials with trillions of dollars designated for the global energy transition.

Assets in investment funds with links to the environment came to almost $2 trillion globally in the first quarter of 2021, more than tripling in just three years, and investors are putting some $3 billion a day into these funds while bonds and loans worth $5 billion looking to bankroll green initiatives are issued every day.

Climate ambitions and power diplomacy

Should the number of zeros fail to persuade, other signs of a sustainability pivot abound. Climate ambition was the driving force in major power diplomacy as France, Germany, China, and the US jostled for leadership positions in a high octane theatre of ‘climate one upmanship’ in the run-up to the Climate Summit hosted by US president Joe Biden. The G7 has agreed to stop international financing of coal projects, and an International Energy Agency report says delivering net zero emissions by 2050 means no new coal, oil, or gas development from now on.

Governments are sending unmistakable policy signals which are redrawing multiple frontiers of the real economy, such as the banning of single use plastic in multiple jurisdictions from Europe, China, and more than 30 African states as well as New York and California. The sale of internal combustion engine vehicles is also set to end by 2035 or sooner in the EU, the UK, and California, and China is expected to follow suit with similar plans. France has proposed a ban on domestic flights when there are less carbon intensive alternatives on the ground.

But these signals did not spring out of a political vacuum. A global climate poll conducted by the United Nations (UN) in 50 countries showed two-thirds of the 1.2 million people polled thought there is a global climate emergency, and most indicated their support for stronger climate action even in countries with strong fossil energy interest.

Real economy responses to noticeable changes in risk calculus and political appetite will likely underpin further rapid shifts in market sentiment as investors begin to fully factor in the scale of the challenge and escalate their interrogation of company-level climate action plans.

Rapid pace of change still needed

But despite this ever-clearer direction of travel and growing availability of new technology and policy options, the need for speed remains. The rationale for moving fast in the next decade and a half to avoid the clear and present threats of environmental and breakdown is increasingly clear.

Getting up to scale is an ongoing and daunting challenge not least because exponential growth has brought growing pains. The recent spat over the definition and the usefulness of net zero targets for corporations and investors as seen in the shareholder votes over the climate plans put forward by Shell and other companies are all testimony to the challenge of mainstreaming.

While some have characterized these debates as political infighting, the reality is higher stakes simply mean it is more important than ever to safeguard the integrity of sustainability commitments as well as the quality of their delivery and implementation.

The move from ‘what’ to ‘how’ points to a clear demand for new, innovative collaborative efforts to help mitigate myriad political economy challenges associated with the upcoming great transition and ensure this sustainability pivot will deliver the promised outcomes. Launching the Chatham House Sustainability Accelerator in support of these once-in-a-generation efforts is a proud moment for the institute, and a clear sign that this pivot to sustainability is here to stay.

Will the next US president invest in Middle East stability or walk away? Expert comment LToremark 17 October 2024

Harris and Trump look set to continue US deprioritization of the region, but they would do better to enlist the support of their partners.

When stability in the Middle East feels so distant, it is much to the dismay of America’s partners that conflict management in the region has fallen down the list of US priorities. As Israel’s war in Gaza has reached its tragic one-year milestone, a new front has opened in Lebanon and further direct escalation between Israel and Iran seems imminent, it is hoped that the next US president will take a bolder role.

Namely, leaders in the UK, Europe and the Middle East are looking to whoever is in the White House to do more to restrain Israel, deliver self-determination – if not a peace process – for Palestine, and contain Iran’s interventionist regional role and nuclear programme.

While it is naive to expect either Kamala Harris or Donald Trump to prioritize conflict management in the Middle East above immigration, the economy, the war in Ukraine or competition with China, the past year has shown the danger of ignoring or sidestepping cascading and glaring regional challenges. 

For Harris or Trump to have a more sustainable impact in the region, they must enlist the support of European, British and Middle Eastern partners and work collectively to build multilateral processes that can set a stronger foundation for regional stability.

Repercussions of deprioritization

The Abraham Accords, which normalized relations between Israel, the UAE and Bahrain, led many to believe that a new era of integration was possible in the Middle East. To some, it also vindicated the US decision to deprioritize the region that had started with Barack Obama’s presidency and his drawing down from ‘forever wars’ in Iraq and Afghanistan. Presidents Trump and Biden continued that approach, encouraging America’s partners in the Middle East to assume greater responsibility for regional stability. Notably, neither renewed negotiations with Iran despite both committing to deliver a stronger deal with Tehran.

The shock of the 7 October attacks shattered that view, and the longer overhang of the US decision to deprioritize the region has visibly played out over the past twelve months. 

While the Biden administration marshalled full political and military support for Israel and there is not – yet – a direct regional war with Iran, the US has been unsuccessful in multiple areas: delivering a ceasefire agreement, securing the release of hostages, maintaining regular humanitarian relief and producing a so-called ‘day after’ plan of action.  

Moreover, the US temporary arrangement with Iran to prevent nuclear acceleration in exchange for marginal sanctions relief has also shown the limits of compartmentalization when managing a portfolio of issues with Tehran.  

No new approach

Trump and Harris’s policy approaches to conflict in the region further show their limited intent to change course on the Middle East. Both leaders are aware that Middle East politics, particularly on Israel–Palestine and Iran – the key issues requiring urgent attention – has become a US partisan minefield that could alienate voters. Despite their different plans, with Trump inclined to be more unilateral, they will both continue the trend of gradually deprioritizing conflict management in favour of greater burden sharing by those in the region.  

President Trump has promised a tougher approach aimed at curtailing conflict and advancing US interests. On Iran, Trump has made clear that he would return to a policy of maximum pressure on the Islamic Republic, perhaps to come to new agreement with Tehran or alternatively to constrain Iran even further.  He has championed his administration’s withdrawal from the 2015 Joint Comprehensive Plan of Action (JCPOA), also known as the Iran nuclear deal. Trump has argued that this approach put economic strain on Iran and reduced its ability to fund proxy groups. 

His advisers have also indicated that they would extend this pressure campaign and provide maximum support to the Iranian opposition and activists. Yet without clear goals or a willingness to negotiate with Tehran to contain further nuclear advancements, the result may well be another round of instability.  

Should he return to office, Trump has indicated that he would immediately put an end to the war in Gaza, though how remains unclear. More broadly, he would likely double down on the agreements to promote Israeli–Saudi normalization and attempt to bypass the Palestinian leadership, focusing on broader regional normalization. But sidestepping Palestinian self-determination, which since 7 October has been the condition for broader Arab normalization, will be difficult for Saudi Arabia to sell to its broader, now politicized, public.  

Many Middle East leaders, including those from the Arabian peninsula, might welcome the return of a Trump presidency, but Trump’s ‘America First’ policy did not provide Arab Gulf leaders, especially Riyadh, with protection from Iran’s attack on Saudi oil facilities seen in September 2019.  

Trump also promised without success to deliver a bigger, better Iran deal that would extend the JCPOA and include compromises on Tehran’s support for proxy groups and constraints on its missile programme. Rather than imposing his previous strategy, a second Trump presidency would be more effective if it worked collaboratively with transatlantic and regional partners on regional security issues pertaining to Israel–Palestine and Iran.  

Continuation and reinforcement?

Despite her recent tough talk on Iran, it is expected that Harris will reinforce the current wave of diplomatic efforts to deescalate and manage tensions with Tehran, rather than advocate for ‘maximum pressure’.  

Harris would likely build on efforts to revive a new paradigm that could contain Iran’s nuclear programme. She is expected to emphasize a strategy of engagement combined with pressure to prevent Iran from obtaining a nuclear weapon, while addressing its regional activities.   

Now that Iran has provided missiles and drones to Russia, it is clear that Tehran’s transfer of lethal aid needs an urgent response beyond continued reliance on sanctions. Harris’s team would be wise to pursue a multilateral negotiation process bringing together Europe and the UK, who are already discussing these issues, to collectively engage Tehran on a broader deal.

Moreover, winning support from Israel and the Gulf is a necessary condition to build a more sustainable Iranian agreement.

Geopolitical corporate responsibility can drive change Expert comment NCapeling 26 July 2022

Russia’s long invasion of Ukraine is testing the commitment of business, but this could see the emergence of a new pillar of support for the rules-based international order.

The massive exit of more than 1,000 international companies from Russia has surpassed – by a factor of nearly ten in merely four months – the number which pulled out of apartheid-led South Africa over an entire decade.

These company exits extend beyond those industries targeted for sanctions – oil and gas, banks and financial services, aerospace, and certain technology sectors – to include hundreds in consumer products ranging from Levi’s and H&M clothing to Coca-Cola and McDonalds. Many of these companies may wish to return to a post-conflict – or post-Putin – Russia, while a few have already sold their Russian operations, as McDonald’s has to an existing Siberian licensee.

Both reputational and operational factors are driving the huge exodus: reputational as companies have chosen to disassociate themselves from Putin’s regime; operational as transportation routes and supply chains have been interrupted.

Few of these companies have made explicit the principles at stake, while many still face ‘tricky legal, operational and ethical considerations’ and some have kept operations in place. But the collective impact of the exit in response to Russia’s affront to international law has sent shockwaves around the world.

Current issues and future implications

Minds now turn to whether this exodus sets a blueprint for the future, and how companies having to make complex and sensitive risk assessments and global business planning decisions can address both current issues as well as similar future challenges.

The new Declaration from the Business for Ukraine Coalition – an international civil society initiative of organizations and individuals – encourages companies to reinforce ‘responsible exit’ from Russia ‘in response to its unprovoked, full-scale war on Ukraine’.

The declaration’s objective is to ‘block access to the economic and financial resources enabling Russian aggression’ and it urgently calls on companies that have terminated or suspended their business operations and relationships to ‘stand by those commitments until the territorial sovereignty of Ukraine within internationally recognized borders is restored.’

It also states companies yet to terminate or suspend operations in Russia should do so unless they can demonstrate through due diligence that their provision of ‘essential’ services or products – such as medicines – meet critical humanitarian needs.

The 2022 Edelman Trust Barometer Special Report: The Geopolitical Business suggests Ukraine represents an inflection point posing ‘a new test’ for business. According to an online survey of 14,000 respondents in 14 countries, including employees, NGOs, and other stakeholders, there is a ‘rising call’ for business to be more engaged in geopolitics, with CEOs ‘expected to shape policy’ on societal and geopolitical issues.

Such expectations have been intensifying with the impetus of the combined stakeholder capitalism and corporate purpose agenda, even as a political backlash in the US against the environmental, social, and governance (ESG) movement linking institutional investors and multinational corporations gains momentum.

The emergence of corporate activism is a further development – partly driven by employees and accelerated during the pandemic – on issues of economic inequality, racial injustice, and gender equality, as well as the climate crisis.

When considering what broader purpose should drive this corporate geopolitical engagement, the Business for Ukraine Declaration offers an answer, calling Russia’s aggression ‘an attack on the rules-based international order which must be protected to ‘safeguard the international community and the global economy.’

This points to broader interests and values at stake in the Russian war on Ukraine because supporting the rules-based international order can become the basis of a new geopolitical corporate responsibility. Business, especially multinational corporations and institutional investors, fundamentally depend on and have enormously benefitted from this order.

Economic development needs a stable rules-based international order

Trade and investment, entrepreneurship, and innovation – the sinews of economic development – depend on predictable, rational behaviour by states at home and abroad. Individual companies and entire industries share a stake in upholding this order at a time when its stability and even legitimacy is undergoing a severe challenge.

The rules-based international order has evolved since the adoption of the UN Charter in 1945, the Universal Declaration of Human Rights in 1948, and the establishment of the standards, norms and institutions that reflect and reinforce these lodestars. It defines the international community, the rule of law, accountable governance, civic freedoms, and human rights within nations. It also supports national self-determination, sovereignty, and the disavowal of the use of force to alter borders among nations, and it provides accountability for genocide, crimes against humanity, and war crimes.

Business has a fundamental stake in the international order as the framework for stability, prosperity, open societies, and markets.

A new geopolitical corporate responsibility does not need to become a doctrine but can instead be an agenda to support the international rules-based order under stress. Such an agenda may help multinationals deal with expectations they already face, such as:

Avoiding situations where they cause, contribute, or are directly linked to human rights abuses. This objective is enshrined in the UN Guiding Principles on Business and Human Rights and companies can be further informed by the new UN Guide to Heightened Human Rights Due Diligence for Business in Conflict-Affected Contexts.

Committing to the ‘shared space’ of the rule of law, accountable governance, civic freedoms, and human rights. These are both the enablers of civil society and the underpinning of sustainable and profitable business and investment environments. The Chatham House synthesis paper The role of the private sector in protecting civic space sets forth the rationale for companies to defend these vital elements.

Supporting peace, justice, and strong institutions both within nations and across the international community as set forth by UN Sustainable Development Goal 16. The SDG 16 Business Framework: Inspiring Transformational Governance shows how companies, as well as national governments and international institutions, can contribute to these building blocks of stability and prosperity.

Demonstrating corporate responsibility at the national and geopolitical levels to enhance equity, transparency, and accountability. Multinationals are already challenged to accept minimum corporate taxation within and across jurisdictions, curb excessive executive compensation, endorse mandatory disclosure of environmental and human rights due diligence, and strengthen corporate governance of ESG risks and responsibilities, including with respect to human rights.

Diminishing inequality by tackling poverty and ensuring sustainability by arresting the climate crisis. Alongside governments and international institutions, the business community already faces increasing pressure to improve its efforts in these areas.

Systemic antibody light chains (AL) amyloidosis is characterized by deposition of amyloid fibrils derived from a particular antibody light chain. Cardiac involvement is a major risk factor for mortality. Using MAS solid-state NMR, we studied the fibril structure of a recombinant light chain fragment corresponding to the fibril protein from patient FOR005, together with fibrils formed by protein sequence variants that are derived from the closest germline (GL) sequence. Both analyzed fibril structures were seeded with ex-vivo amyloid fibrils purified from the explanted heart of this patient. We find that residues 11-42 and 69-102 adopt β-sheet conformation in patient protein fibrils. We identify arginine-49 as a key residue that forms a salt bridge to aspartate-25 in the patient protein fibril structure. In the germline sequence, this residue is replaced by a glycine. Fibrils from the GL protein and from the patient protein harboring the single point mutation R49G can be both heterologously seeded using patient ex-vivo fibrils. Seeded R49G fibrils show an increased heterogeneity in the C-terminal residues 80-102, which is reflected by the disappearance of all resonances of these residues. By contrast, residues 11-42 and 69-77, which are visible in the MAS solid-state NMR spectra, show 13Cα chemical shifts that are highly like patient fibrils. The mutation R49G thus induces a conformational heterogeneity at the C terminus in the fibril state, whereas the overall fibril topology is retained. These findings imply that patient mutations in FOR005 can stabilize the fibril structure.

Methionine, through S-adenosylmethionine, activates a multifaceted growth program in which ribosome biogenesis, carbon metabolism, and amino acid and nucleotide biosynthesis are induced. This growth program requires the activity of the Gcn4 transcription factor (called ATF4 in mammals), which facilitates the supply of metabolic precursors that are essential for anabolism. However, how Gcn4 itself is regulated in the presence of methionine is unknown. Here, we discover that Gcn4 protein levels are increased by methionine, despite conditions of high cell growth and translation (in which the roles of Gcn4 are not well-studied). We demonstrate that this mechanism of Gcn4 induction is independent of transcription, as well as the conventional Gcn2/eIF2α-mediated increased translation of Gcn4. Instead, when methionine is abundant, Gcn4 phosphorylation is decreased, which reduces its ubiquitination and therefore degradation. Gcn4 is dephosphorylated by the protein phosphatase 2A (PP2A); our data show that when methionine is abundant, the conserved methyltransferase Ppm1 methylates and alters the activity of the catalytic subunit of PP2A, shifting the balance of Gcn4 toward a dephosphorylated, stable state. The absence of Ppm1 or the loss of the PP2A methylation destabilizes Gcn4 even when methionine is abundant, leading to collapse of the Gcn4-dependent anabolic program. These findings reveal a novel, methionine-dependent signaling and regulatory axis. Here methionine directs the conserved methyltransferase Ppm1 via its target phosphatase PP2A to selectively stabilize Gcn4. Through this, cells conditionally modify a major phosphatase to stabilize a metabolic master regulator and drive anabolism.

Visual Abstract

The Wnt/β-catenin pathway is one of the major pathways that regulates embryonic development, adult homeostasis, and stem cell self-renewal. In this pathway, transcription factors T-cell factor and lymphoid enhancer factor (TCF/LEF) serve as a key switch to repress or activate Wnt target gene transcription by recruiting repressor molecules or interacting with the β-catenin effector, respectively. It has become evident that the protein stability of the TCF/LEF family members may play a critical role in controlling the activity of the Wnt/β-catenin signaling pathway. However, factors that regulate the stability of TCF/LEFs remain largely unknown. Here, we report that pVHL binding protein 1 (VBP1) regulates the Wnt/β-catenin signaling pathway by controlling the stability of TCF/LEFs. Surprisingly, we found that either overexpression or knockdown of VBP1 decreased Wnt/β-catenin signaling activity in both cultured cells and zebrafish embryos. Mechanistically, VBP1 directly binds to all four TCF/LEF family members and von Hippel-Lindau tumor-suppressor protein (pVHL). Either overexpression or knockdown of VBP1 increases the association between TCF/LEFs and pVHL and then decreases the protein levels of TCF/LEFs via proteasomal degradation. Together, our results provide mechanistic insights into the roles of VBP1 in controlling TCF/LEFs protein stability and regulating Wnt/β-catenin signaling pathway activity.

Genetic mutations related to ALS, a progressive neurological disease, have been discovered in the gene encoding σ-1 receptor (σ1R). We previously reported that σ1RE102Q elicits toxicity in cells. The σ1R forms oligomeric states that are regulated by ligands. Nevertheless, little is known about the effect of ALS-related mutations on oligomer formation. Here, we transfected NSC-34 cells, a motor neuronal cell line, and HEK293T cells with σ1R-mCherry (mCh), σ1RE102Q-mCh, or nontagged forms to investigate detergent solubility and subcellular distribution using immunocytochemistry and fluorescence recovery after photobleaching. The oligomeric state was determined using crosslinking procedure. σ1Rs were soluble to detergents, whereas the mutants accumulated in the insoluble fraction. Within the soluble fraction, peak distribution of mutants appeared in higher sucrose density fractions. Mutants formed intracellular aggregates that were co-stained with p62, ubiquitin, and phosphorylated pancreatic eukaryotic translation initiation factor-2-α kinase in NSC-34 cells but not in HEK293T cells. The aggregates had significantly lower recovery in fluorescence recovery after photobleaching. Acute treatment with σ1R agonist SA4503 failed to improve recovery, whereas prolonged treatment for 48 h significantly decreased σ1RE102Q-mCh insolubility and inhibited apoptosis. Whereas σ1R-mCh formed monomers and dimers, σ1RE102Q-mCh also formed trimers and tetramers. SA4503 reduced accumulation of the four types in the insoluble fraction and increased monomers in the soluble fraction. The σ1RE102Q insolubility was diminished by σ1R-mCh co-expression. These results suggest that the agonist and WT σ1R modify the detergent insolubility, toxicity, and oligomeric state of σ1RE102Q, which may lead to promising new treatments for σ1R-related ALS.

Apolipoprotein A-I (ApoA-I) of high-density lipoprotein (HDL) is essential for the transportation of cholesterol between peripheral tissues and the liver. However, specific mutations in Apolipoprotein A-I (ApoA-I) of high-density lipoprotein (HDL) are responsible for a late-onset systemic amyloidosis, the pathological accumulation of protein fibrils in tissues and organs. Carriers of these mutations do not exhibit increased cardiovascular disease risk despite displaying reduced levels of ApoA-I/ HDL-cholesterol. To explain this paradox, we show that the HDL particle profile of patients carrying either L75P or L174S ApoA-I amyloidogenic variants a higher relative abundance of the 8.4 nm vs 9.6 nm particles, and that serum from patients, as well as reconstituted 8.4 and 9.6 nm HDL particles (rHDL), possess increased capacity to catalyze cholesterol efflux from macrophages. Synchrotron radiation circular dichroism and hydrogen-deuterium exchange revealed that the variants in 8.4 nm rHDL have altered secondary structure composition and display a more flexible binding to lipids compared to their native counterpart. The reduced HDL-cholesterol levels of patients carrying ApoA-I amyloidogenic variants are thus balanced by higher proportion of small, dense HDL particles and better cholesterol efflux due to altered, region-specific protein structure dynamics.

Accompanied with nutrition transition, non-HDL-C levels of individuals in Asian countries has increased rapidly, which has caused the global epicenter of nonoptimal cholesterol to shift from Western countries to Asian countries. Thus, it is critical to underline major genetic and dietary determinants. In the current study of 2,330 Chinese individuals, genetic risk scores (GRSs) were calculated for total cholesterol (TC; GRS_TC, 57 SNPs), LDL-C (GRS_LDL-C, 45 SNPs), and HDL-C (GRS_HDL-C, 65 SNPs) based on SNPs from the Global Lipid Genetics Consortium study. Cholesterol intake was estimated by a 74-item food-frequency questionnaire. Associations of dietary cholesterol intake with plasma TC and LDL-C strengthened across quartiles of the GRS_TC (effect sizes: –0.29, 0.34, 2.45, and 6.47; P_interaction = 0.002) and GRS_LDL-C (effect sizes: –1.35, 0.17, 5.45, and 6.07; P_interaction = 0.001), respectively. Similar interactions with non-HDL-C were observed between dietary cholesterol and GRS_TC (P_interaction = 0.001) and GRS_LDL-C (P_interaction = 0.004). The adverse effects of GRS_TC on TC (effect sizes across dietary cholesterol quartiles: 0.51, 0.82, 1.21, and 1.31; P_interaction = 0.023) and GRS_LDL-C on LDL-C (effect sizes across dietary cholesterol quartiles: 0.66, 0.52, 1.12, and 1.56; P_interaction = 0.020) were more profound in those having higher cholesterol intake compared with those with lower intake. Our findings suggest significant interactions between genetic susceptibility and dietary cholesterol intake on plasma cholesterol profiles in a Chinese population.

Spatial changes of FAs in the retina in response to different dietary n-3 formulations have never been explored, although a diet rich in EPA and DHA is recommended to protect the retina against the effects of aging. In this study, Wistar rats were fed for 8 weeks with balanced diet including either EPA-containing phospholipids (PLs), EPA-containing TGs, DHA-containing PLs, or DHA-containing TGs. Qualitative changes in FA composition of plasma, erythrocytes, and retina were evaluated by gas chromatography-flame ionization detector. Following the different dietary intakes, changes to the quantity and spatial organization of PC and PE species in retina were determined by LC coupled to MS/MS and MALDI coupled to MS imaging. The omega-3 content in the lipids of plasma and erythrocytes suggests that PLs as well as TGs are good omega-3 carriers for retina. However, a significant increase in DHA content in retina was observed, especially molecular species as di-DHA-containing PC and PE, as well as an increase in very long chain PUFAs (more than 28 carbons) following PL-EPA and TG-DHA diets only. All supplemented diets triggered spatial organization changes of DHA in the photoreceptor layer around the optic nerve. Taken together, these findings suggest that dietary omega-3 supplementation can modify the content of FAs in the rat retina.

Lipins are eukaryotic proteins with functions in lipid synthesis and the homeostatic control of energy balance. They execute these functions by acting as phosphatidate phosphatase enzymes in the cytoplasm and by changing gene expression after translocation into the cell nucleus, in particular under fasting conditions. Here, we asked whether nuclear translocation and the enzymatic activity of Drosophila Lipin serve essential functions and how gene expression changes, under both fed and fasting conditions, when nuclear translocation is impaired. To address these questions, we created a Lipin null mutant, a mutant expressing Lipin lacking a nuclear localization signal (Lipin^NLS), and a mutant expressing enzymatically dead Lipin. Our data support the conclusion that the enzymatic but not nuclear gene regulatory activity of Lipin is essential for survival. Notably, adult Lipin^NLS flies were not only viable but also exhibited improved life expectancy. In contrast, they were highly susceptible to starvation. Both the improved life expectancy in the fed state and the decreased survival in the fasting state correlated with changes in metabolic gene expression. Moreover, increased life expectancy of fed flies was associated with a decreased metabolic rate. Interestingly, in addition to metabolic genes, genes involved in feeding behavior and the immune response were misregulated in Lipin^NLS flies. Altogether, our data suggest that the nuclear activity of Lipin influences the genomic response to nutrient availability with effects on life expectancy and starvation resistance. Thus, nutritional or therapeutic approaches that aim at lowering nuclear translocation of lipins in humans may be worth exploring.

Beiging of white adipose tissue (WAT) has beneficial effects on metabolism. Although it is known that beige adipocytes are active in lipid catabolism and thermogenesis, how they are regulated deserves more explorations. In this study, we demonstrate that stearoyl-CoA desaturase 1 (SCD1) in subcutaneous WAT (scWAT) responded to cold stimulation and was able to promote mobilization of triacylglycerol [TAG (triglyceride)]. In vitro studies showed that SCD1 promoted lipolysis in C3H10T1/2 white adipocytes. The lipolytic effect was contributed by one of SCD1’s products, oleic acid (OA). OA upregulated adipose TAG lipase and hormone-sensitive lipase expression. When SCD1 was overexpressed in the scWAT of mice, lipolysis was enhanced, and oxygen consumption and heat generation were increased. These effects were also demonstrated by the SCD1 knockdown experiments in mice. In conclusion, our study suggests that SCD1, known as an enzyme for lipid synthesis, plays a role in upregulating lipid mobilization through its desaturation product, OA.

The divalent anion sodium symporter (DASS) family (SLC13) plays critical roles in metabolic homeostasis, influencing many processes, including fatty acid synthesis, insulin resistance, and adiposity. DASS transporters catalyze the Na+-driven concentrative uptake of Krebs cycle intermediates and sulfate into cells; disrupting their function can protect against age-related metabolic diseases and can extend lifespan. An inward-facing crystal structure and an outward-facing model of a bacterial DASS family member, VcINDY from Vibrio cholerae, predict an elevator-like transport mechanism involving a large rigid body movement of the substrate-binding site. How substrate binding influences the conformational state of VcINDY is currently unknown. Here, we probe the interaction between substrate binding and protein conformation by monitoring substrate-induced solvent accessibility changes of broadly distributed positions in VcINDY using a site-specific alkylation strategy. Our findings reveal that accessibility to all positions tested is modulated by the presence of substrates, with the majority becoming less accessible in the presence of saturating concentrations of both Na+ and succinate. We also observe separable effects of Na+ and succinate binding at several positions suggesting distinct effects of the two substrates. Furthermore, accessibility changes to a solely succinate-sensitive position suggests that substrate binding is a low-affinity, ordered process. Mapping these accessibility changes onto the structures of VcINDY suggests that Na+ binding drives the transporter into an as-yet-unidentified conformational state, involving rearrangement of the substrate-binding site–associated re-entrant hairpin loops. These findings provide insight into the mechanism of VcINDY, which is currently the only structurally characterized representative of the entire DASS family.

Secrets and Spies: UK Intelligence Accountability After Iraq and Snowden Book sysadmin 15 January 2020

How can democratic governments hold intelligence and security agencies to account when what they do is largely secret? Jamie Gaskarth explores how intelligence professionals view accountability in the context of 21st century politics.

Using the UK as a case study, this book provides the first systematic exploration of how accountability is understood inside the secret world. It is based on new interviews with current and former UK intelligence practitioners, as well as extensive research into the performance and scrutiny of the UK intelligence machinery.

The result is the first detailed analysis of how intelligence professionals view their role, what they feel keeps them honest, and how far external overseers impact on their work.

The UK gathers material that helps inform global decisions on such issues as nuclear proliferation, terrorism, transnational crime, and breaches of international humanitarian law. On the flip side, the UK was a major contributor to the intelligence failures leading to the Iraq war in 2003, and its agencies were complicit in the widely discredited U.S. practices of torture and ‘rendition’ of terrorism suspects. UK agencies have come under greater scrutiny since those actions, but it is clear that problems remain.

Secrets and Spies is the result of a British Academy funded project (SG151249) on intelligence accountability. The book is published as part of the Insights series.

Tumor hypoxia, an integral biomarker to guide radiotherapy, can be imaged with ¹⁸F-fluoromisonidazole (¹⁸F-FMISO) hypoxia PET. One major obstacle to its broader application is the lack of standardized interpretation criteria. We sought to develop and validate practical interpretation criteria and a dedicated training protocol for nuclear medicine physicians to interpret ¹⁸F-FMISO hypoxia PET. Methods: We randomly selected 123 patients with human papillomavirus–positive oropharyngeal cancer enrolled in a phase II trial who underwent 123 ¹⁸F-FDG PET/CT and 134 ¹⁸F-FMISO PET/CT scans. Four independent nuclear medicine physicians with no ¹⁸F-FMISO experience read the scans. Interpretation by a fifth nuclear medicine physician with over 2 decades of ¹⁸F-FMISO experience was the reference standard. Performance was evaluated after initial instruction and subsequent dedicated training. Scans were considered positive for hypoxia by visual assessment if ¹⁸F-FMISO uptake was greater than floor-of-mouth uptake. Additionally, SUV_max was determined to evaluate whether quantitative assessment using tumor-to-background ratios could be helpful to define hypoxia positivity. Results: Visual assessment produced a mean sensitivity and specificity of 77.3% and 80.9%, with fair interreader agreement ( = 0.34), after initial instruction. After dedicated training, mean sensitivity and specificity improved to 97.6% and 86.9%, with almost perfect agreement ( = 0.86). Quantitative assessment with an estimated best SUV_max ratio threshold of more than 1.2 to define hypoxia positivity produced a mean sensitivity and specificity of 56.8% and 95.9%, respectively, with substantial interreader agreement ( = 0.66), after initial instruction. After dedicated training, mean sensitivity improved to 89.6% whereas mean specificity remained high at 95.3%, with near-perfect interreader agreement ( = 0.86). Conclusion: Nuclear medicine physicians without ¹⁸F-FMISO hypoxia PET reading experience demonstrate much improved interreader agreement with dedicated training using specific interpretation criteria.
