Stop covid with CRISPR Diagnostics

With Crispr, a Possible Quick Test for the Coronavirus

Sherlock's quick, CRISPR-based coronavirus test gets emergency nod

STOP COVID

Point-of-care testing for COVID-19 using SHERLOCK diagnostics

Great!

The FDA granted its first emergency authorization for a CRISPR-based test for COVID-19, developed by Sherlock Biosciences, designed to turn results around in about an hour compared to the four to six hours needed for other molecular diagnostics.
The test is based on the company’s namesake technology, SHERLOCK, short for Specific High-sensitivity Enzymatic Reporter unLOCKing, a Cas13a-based CRISPR system that targets RNA rather than DNA. It looks for an RNA sequence specific to SARS-CoV-2, the virus that causes COVID-19, in patient samples taken from the upper airways with a swab or from airways in the lungs known as bronchoalveolar washing.
“If it’s there, it attaches to the Cas13 enzyme and activates it, which leads to the chewing up and cleaving of RNA probes,” Sherlock CEO Rahul Dhanda told FierceMedTech. When cleaved, those RNA molecules release a fluorescent signal to show the virus is present.

Gates on the pandemic

Responding to Covid-19 — A Once-in-a-Century Pandemic?

Bill Gates says in NEJM:

The long-term challenge — improving our ability to respond to outbreaks — isn’t new. global health experts have been saying for years that another pandemic whose speed and severity rivaled those of the 1918 influenza epidemic was a matter not of if but of when. The Bill and Melinda Gates Foundation has committed substantial resources in recent years to helping the world prepare for such a scenario.

Finally, governments and industry will need to come to an agreement: during a pandemic, vaccines and antivirals can’t simply be sold to the highest bidder. They should be available and affordable for people who are at the heart of the outbreak and in greatest need. Not only is such distribution the right thing to do, it’s also the right strategy for short-circuiting transmission and preventing future pandemics. These are the actions that leaders should be taking now. There is no time to waste.

Paying providers and adjusting for quality and performance

Payment Methods and Benefit Designs: How They Work and How They Work Together to Improve Health Care

Value-Based Provider Payment Initiatives Combining Global Payments With Explicit Quality Incentives: A Systematic Review

Figure 1. Core components and associated design features of a VBP model combining global base payments with explicit quality incentives.

In the coming years, VBP models stimulating value in a broad sense will likely continue to gain ground, as the quest toward VBHC proceeds. This article demonstrates that VBP models consisting of global base payments combined with explicit quality incentives are operationalized in practice in various ways. In addition, our results show that this particular VBP model has the potential to improve value and contribute to VBHC. Going forward, this article may serve as inspirational material for those interested in developing new or improving on existing VBP models.

Behavioral contagion

Under the Influence: Putting Peer Pressure to Work

So much has been written on behavioral economics and nudging, and I always think about the implications. Robert Frank in his new book provides new insights to understand the behavioral contagion among all of us. He says:

The argument I will defend in this book, implicit in several of the examples already discussed, is summarized in the following seven premises:
1. Context shapes our choices to a far greater extent than many people consciously realize.
2. The influence of context is sometimes positive (as when people become more likely to exercise regularly and eat sensibly if they live in communities where most of their neighbors do likewise).
3. Other times, the influence of context is negative (as when people who live amidst smokers become more likely to smoke, or when neighboring business owners erect ugly signs).
4. The contexts that shape our choices are themselves the collective result of the individual choices we make.
5. But because each individual choice has only a negligible effect on those contexts, rational, self-interested individuals typically ignore the feedback loops described in premise 4.
6. We could often achieve better outcomes by taking collective steps to encourage choices that promote beneficial contexts and discourage harmful ones.
7. To promote better environments, taxation is often more effective and less intrusive than regulation.

Among behavioral scientists, the first five of these premises are completely uncontroversial. It is only 6 and 7 that provoke disagreement. Regarding 6, even when everyone acknowledges that behavioral contagion causes harm, as in the smoking example, it is often hard to reach consensus on collective actions that would modify the contexts that shape our actions. In part, the difficulty is that individual incentives and collective incentives often diverge so sharply. But objections to premise 6 are also rooted in the long American tradition of hostility toward regulations generally. Nor can there be any presumption that regulation always improves matters. Markets sometimes fail to deliver optimal results, but government interventions are also imperfect. Premise 7 is controversial simply because many people dislike being taxed. Yet a moment’s reflection reveals that the only interesting questions in this domain concern not whether we should tax but rather which things we should tax and at what rates. Whether you’re a small-government conservative or an expansive progressive, tax revenue is necessary to pay for valued public services.

A must read. The book has clear messages for professionalism in Medicine and for pandemics.

How testing market fails during a pandemic

What Caused the COVID-19 Testing Deficit?

The evidence of market failure during this pandemic is everywhere. Shortages, excessive prices, unavailable capacity...It is a clear example of mismatch between demand and supply. The question is, Can we do it otherwise?. In this article there are some hints for resource allocation for testing activities.

Globally, the development of diagnostics has long been left to markets, many of which are highly specialized. But while there are diagnostics markets for major infectious and non-infectious diseases, and even neglected tropical diseases, there is none for pandemic diseases.
Governments can of course counteract market deficiencies, but the commonly used mechanisms still require a trace level of demand, which does not exist for pandemic-disease diagnostics until the brink of an outbreak. And national governments, subject as they are to political and ideological constraints, cannot be relied upon always to create markets with the same swiftness demonstrated by South Korea. Reactive market creation is therefore not the way forward.
Instead, national governments should support the creation of a global coordinating platform for pandemic preparedness. Such a platform can take the lead in raising and pooling capital to channel toward rapid development, production, and distribution of diagnostics for pandemic diseases.
The blueprint for such a platform already exists. The Coalition for Epidemic Preparedness Innovations (CEPI) is a coordinating mechanism focused on advancing vaccine development and facilitating clinical validation, mass-scale manufacturing, and stockpiling. By reducing uncertainty and minimizing disruptions, CEPI makes vaccine markets more secure, accessible, and dynamic.
CEPI relies on both traditional financing (large grants from governments and foundations) and innovative financing (the returns from instruments like the International Finance Facility for Immunization, or IFFIm). In the event of an outbreak, CEPI uses instruments like Advanced Market Commitments (AMCs) or volume guarantees – which can be structured through mechanisms like the Global Health Investment Fund and InnovFin, or as conditional pledges to IFFIm and Gavi, the Vaccine Alliance – to enable it to scale up production quickly.
This blueprint can easily be replicated for diagnostics. All that is needed is a specialized entity – an institution or initiative that couples research and development with market access. 

Health vs. wealth in a pandemic

HEALTH VS. WEALTH? PUBLIC HEALTH POLICIES AND THE ECONOMY DURING
COVID-19

A NBER paper says:

A pandemic can impact an economy in many ways: reductions in people’s willingness
to work, dislocations in consumption patterns and lower consumption, added stress on the financial system, and greater uncertainty leading to lower investment. These are
respectively referred to as (labor) supply shocks, demand shocks, financial shocks and
uncertainty shocks. Connected economies and epidemiological communities also move in synch. Even a healthy economy, or an economy that has not mandated a shutdown, may feel the impact of external events. With the exception of the 1918 influenza, recent
pandemics have neither had as large of a global impact, nor has there been as much real
time data available to empirically assess the economic and public health impact of NPIs.
We study outcomes during the Covid-19 pandemic.
We have three main results. First, our analysis shows NPIs may have been effective
in slowing the growth rate of confirmed cases of Covid-19 but not in decreasing the growth rate of cumulative mortality. Second, we find evidence of spillovers. NPIs may have impacts on other jurisdictions. Finally, there is little evidence that NPIs are associated with larger declines in local economic activity than in places without NPIs.

Against patents for the current pandemic

Patents vs. the Pandemic

Imagine a world in which a global network of medical professionals monitored for emerging strains of a contagious virus, periodically updated an established formula for vaccinating against it, and then made that information available to companies and countries around the world. Moreover, imagine if this work were done without any intellectual-property (IP) considerations, and without pharmaceutical monopolies exploiting a desperate public to maximize their profits.
This may sound like a utopian fantasy, but it is actually a description of how the flu vaccine has been produced for the past 50 years. Through the World Health Organization’s Global Influenza Surveillance and Response System, experts from around the world convene twice a year to analyze and discuss the latest data on emerging flu strains, and to decide which strains should be included in each year’s vaccine.

This is exactly what Nobel prize David Stiglitz says in his op-ed in Project Syndicate. Absolutely agree.

For too long, we have bought into the myth that today’s IP regime is necessary. The proven success of GISRS and other applications of “open science” shows that it is not. With the COVID-19 death toll rising, we should question the wisdom and morality of a system that silently condemns millions of human beings to suffering and death every year.
It’s time for a new approach. Academics and policymakers have already come forward with many promising proposals for generating socially useful – rather than merely profitable – pharmaceutical innovation. There has never been a better time to start putting these ideas into practice.
