Learning the ABCs of ATP release [Signal Transduction]

ATP plays important roles outside the cell, but the mechanism by which it is arrives in the extracellular environment is not clear. Dunn et al. now show that decreases in cellular cholesterol levels mediated by the ABCG1 transporter increase ATP release by volume-regulated anion channels under hypotonic conditions. Importantly, these results may imply that cells that handle cholesterol differently might experience differential extracellular ATP release during hypotonicity.

Projection-space implementation of deep learning-guided low-dose brain PET imaging improves performance over implementation in image-space

Purpose: To assess the performance of full dose (FD) positron emission tomography (PET) image synthesis in both image and projection space from low-dose (LD) PET images/sinograms without sacrificing diagnostic quality using deep learning techniques. Methods: Clinical brain PET/CT studies of 140 patients were retrospectively employed for LD to FD PET conversion. 5% of the events were randomly selected from the FD list-mode PET data to simulate a realistic LD acquisition. A modified 3D U-Net model was implemented to predict FD sinograms in the projection-space (PSS) and FD images in image-space (PIS) from their corresponding LD sinograms/images, respectively. The quality of the predicted PET images was assessed by two nuclear medicine specialists using a five-point grading scheme. Quantitative analysis using established metrics including the peak signal-to-noise ratio (PSNR), structural similarity index metric (SSIM), region-wise standardized uptake value (SUV) bias, as well as first-, second- and high-order texture radiomic features in 83 brain regions for the test and evaluation dataset was also performed. Results: All PSS images were scored 4 or higher (good to excellent) by the nuclear medicine specialists. PSNR and SSIM values of 0.96 ± 0.03, 0.97 ± 0.02 and 31.70 ± 0.75, 37.30 ± 0.71 were obtained for PIS and PSS, respectively. The average SUV bias calculated over all brain regions was 0.24 ± 0.96% and 1.05 ± 1.44% for PSS and PIS, respectively. The Bland-Altman plots reported the lowest SUV bias (0.02) and variance (95% CI: -0.92, +0.84) for PSS compared with the reference FD images. The relative error of the homogeneity radiomic feature belonging to the Grey Level Co-occurrence Matrix category was -1.07 ± 1.77 and 0.28 ± 1.4 for PIS and PSS, respectively Conclusion: The qualitative assessment and quantitative analysis demonstrated that the FD PET prediction in projection space led to superior performance, resulting in higher image quality and lower SUV bias and variance compared to FD PET prediction in the image domain.

Financial Markets: Lessons Learned Since the Financial Crisis and What the Future Holds

Invitation Only Research Event

2 September 2019 - 5:15pm to 6:30pm

Chatham House | 10 St James's Square | London | SW1Y 4LE

Event participants

Professor Robert Shiller, Sterling Professor of Economics, Yale University
Chair: Marianne Schneider-Petsinger, Research Fellow, US and the Americas Programme Chatham House

The 2007-08 financial crisis wreaked havoc on the lives of millions of people across the globe, and upended the faith of many in the prevailing economic system, with many countries still recovering a decade on.

Drawing on extensive research in his new book, Narrative Economics: How Stories Go Viral and Drive Major Economic Events, Professor Shiller will draw on a rich array of historical examples and data and outline a new way to think about economic change, and the narratives that shape it, to provide answers to questions such as whether lessons have been learned since the last financial crisis, are the same dislocations likely to occur again and what toolkits, if any, are there for anticipating the next financial crisis or recession?

Attendance at this event is by invitation only.

The Academic NDA: Justification, Process, and Lessons Learned

The University of Iowa recently completed a 4-y expedition into the uncharted waters of the Food and Drug Administration (FDA) new-drug application (NDA) process that ultimately resulted in approval of 68Ga-DOTATOC in August 2019. The journey was enlightening, revealing a highly structured, arcane, but rigorous regulatory approval process. The FDA proved to be an efficient, reasonable, and communicative regulatory body that achieved balance between support of the initiative and its mission-bound, process-bound duty to ensure that the application met the expected safety and efficacy standards of the agency. With several clinically valuable PET radiopharmaceuticals without intellectual property residing in regulatory limbo, without industry champions to bring them to marketing approval, there may be justification for a more concerted effort from the molecular imaging community into generating better understanding, support, and perhaps even infrastructure for the academic NDA. As a first step, this article briefly describes the start-to-finish story for 68Ga-DOTATOC, including a description of the clinical trials, a broad overview of the structured content of the NDA document, and the distilled experiences associated with the 68Ga-DOTATOC NDA process. It is anticipated that with sustained free sharing of information relating to the FDA drug registration process, it will prove less daunting and more efficient in future academically sponsored NDA filings for PET imaging agents.

How Can the EU Learn the Language of Power?

3 December 2019

The new EU foreign policy chief, Josep Borrell, has an eye-catching declaration of intent. But what does it mean in practice?

2019-12-03-Borrell.jpg

The new European Commission has finally started its work this week. In a world increasingly defined by great power competition and deprived of the certainties of a strong transatlantic partnership, this might well be the first commission where foreign and security policy issues will be equally important to internal EU ones.

Amid an escalating Sino-American rivalry, there is a growing realization in Brussels that something has to change in the way the EU thinks and acts internationally.

Charting a more successful path forward will not be easy. Josep Borrell, the EU’s new high representative for foreign affairs and security policy, during his confirmation hearing, offered a hint as to what might be needed to get there: ‘The EU has to learn to use the language of power.”’

What might this mean in practice?

Four issues illustrate some of the key dilemmas ahead for the EU and its new executive.

Hard power

The most revealing of these concerns hard power.

For a union so addicted to the US security guarantee, and so used to the softer approaches of exercising its influence, this was always going to be a difficult discussion. The recent disagreement between Germany and France over the future of NATO gave a taste of how fraught and complex this discussion can be.

Underpinning it are three fundamental questions. If the EU has to enhance its capacity to defend its interests with military power, how (and how quickly) is it to move ahead, how much additional responsibility will that mean and to what degree will this responsibility need to be shouldered autonomously, potentially distancing itself from NATO or Washington? Moving forward with this agenda while balancing the competing interests of member states and preserving the fragile progress already achieved with initiatives such as PESCO will not be easy.

Discussion and debate among member states should not be discouraged, but the new commission has a role to play in ensuring that such discussion is constructive. Distracting talks about an EU army or a nuclear ‘Eurodeterrent’ should be shelved, with the focus as much as possible on acquiring tangible capabilities, getting the defence architecture right, ensuring operational readiness and spending defence budgets smartly.

How to use power

Great powers have traditionally been able to cooperate in certain areas while competing in others. Given their wide reach, powers like the US have generally not allowed disagreement on one issue to interfere with the ability to work together on others.

If the EU aspires to be a more assertive global player, it will need to grow comfortable with this compartmentalization. For example, if Brussels wants to stand up to Beijing regarding human rights, the South China Sea or issues of acquisition of European infrastructure, this should not mean that cooperation on areas such as peacekeeping, arms control or climate change needs to be blocked.

Footing the bill

Ursula von der Leyen, the new commission president, has announced that she wants an increase of 30% for external action in the 2021–27 Multi-annual Financial Framework (the EU budget). But with the Brexit budget gap looming, and little appetite to increase contributions or reduce the funds allocated to costly schemes, like the Common Agricultural Policy, compromises will have to be made for this to happen.

This will be one of the first key tests for the new commission. Power costs money, not just gestures, and therefore specific commitments already made under the Juncker mandate regarding the European Defence Fund or the new Neighbourhood, Development and International Cooperation Instrument need to be guaranteed, if not expanded.

Internal politics

None of these steps are possible if the internal workings of the EU become too dysfunctional. A stronger stance internationally would make the sometime incoherence of internal EU management more of a liability to the bloc’s credibility. For example, how can the EU advocate for the rule of law beyond its borders while some of its own member states violate the same principles? 

And there remains the perpetual question of how much more power member states are willing to cede – if any – to deliver faster and more efficient decision-making. If the bloc’s reflexes – often slow, consensual and risk averse – are out of place with the role of a modern great power, how does the commission envision introducing decision-making mechanisms, like qualified majority voting, in foreign and security policy matters?

Borrell’s résumé shows his extensive experience in handling critical policy dossiers. He is also expected to travel less than his predecessor, being mindful of the even heavier institutional work ahead, not least in working with a more politically fragmented European Council and a more politicized European Parliament.

Ultimately, learning the language of power might mean that the EU finally deals with the basics of international affairs as a coherent and cohesive actor, rather than as an occasional ensemble. This endeavour clearly lacks a fixed path or destination. But the new commission seems to be mindful that the EU will have to find new ways to use power as the world changes around it. In doing so, it should keep in mind that the language of power is best articulated not with words, but with actions.

Predicting the Risk of Inpatient Hypoglycemia With Machine Learning Using Electronic Health Records

OBJECTIVE

We analyzed data from inpatients with diabetes admitted to a large university hospital to predict the risk of hypoglycemia through the use of machine learning algorithms.

RESEARCH DESIGN AND METHODS

Four years of data were extracted from a hospital electronic health record system. This included laboratory and point-of-care blood glucose (BG) values to identify biochemical and clinically significant hypoglycemic episodes (BG ≤3.9 and ≤2.9 mmol/L, respectively). We used patient demographics, administered medications, vital signs, laboratory results, and procedures performed during the hospital stays to inform the model. Two iterations of the data set included the doses of insulin administered and the past history of inpatient hypoglycemia. Eighteen different prediction models were compared using the area under the receiver operating characteristic curve (AUROC) through a 10-fold cross validation.

RESULTS

We analyzed data obtained from 17,658 inpatients with diabetes who underwent 32,758 admissions between July 2014 and August 2018. The predictive factors from the logistic regression model included people undergoing procedures, weight, type of diabetes, oxygen saturation level, use of medications (insulin, sulfonylurea, and metformin), and albumin levels. The machine learning model with the best performance was the XGBoost model (AUROC 0.96). This outperformed the logistic regression model, which had an AUROC of 0.75 for the estimation of the risk of clinically significant hypoglycemia.

CONCLUSIONS

Advanced machine learning models are superior to logistic regression models in predicting the risk of hypoglycemia in inpatients with diabetes. Trials of such models should be conducted in real time to evaluate their utility to reduce inpatient hypoglycemia.
