  • Solving the Pandemic After the Pandemic-
    Long COVID affects millions. It illustrates the need for a new medical paradigm.
    Reviewed by Tyler Woods

    KEY POINTS-
    Long COVID research has been pioneered by patients, with the medical establishment playing catch-up.
    A new paradigm for patient-centered health care is emerging, emboldened by new technological advances.
    A new bottom-up approach for pursuing research could transform care for many hard-to-treat diseases.
    We now stand at the meeting of two eternities, to borrow a line from Henry David Thoreau: the past and future.

    That is the present moment.
    On May 11, the Biden administration is slated to end the public health emergency for the COVID-19 pandemic. But although certain government services will end, the virus won't stop replicating and spreading, and its long-term effects on our immune systems still carry the same level of risk.

    For tens of millions of people around the world, "the pandemic after the pandemic" is well underway.

    Study after study shows that 10 to 30 percent of those infected with COVID-19 go on to develop symptoms of long COVID, including debilitating fatigue, post-exertional malaise, and brain fog, among as many as 200 other symptoms. A study from Harvard economist David Cutler estimates the long-term economic toll of long COVID at $3.7 trillion in the U.S. alone, a number that is on par with the Great Recession.

    In shifting to this new phase of the pandemic, it's essential to refocus an all-of-society endeavor to offer treatments, services, and support for COVID long-haulers to preserve their dignity and their dreams.

    As a society, we have always rallied to visions at the frontiers of the imagination: staring down the totalitarian menace in Europe during World War II, landing on the moon, and developing a vaccine in record time to quell the tide of a global pandemic. That's the magic of thinking big.

    But just as we developed public-private vaccine distribution through Operation Warp Speed, we need a similarly ambitious set of policies to reckon with the long tail of the virus, how it's etched itself into the lives of tens of millions around the world in myriad ways seen and unseen. Many have debilitating symptoms that never left them after their infection; others carry invisible organ damage that leaves them vulnerable to sudden heart attacks or strokes years from now.

    We need an Operation Warp Speed for long COVID.
    As the public health emergency is set to end, there is no more important time in a generation to be evaluating how many important lessons the pandemic has taught us about ourselves and society, and how we can leverage this moment toward a new, better normal for science and health equity. So far, innovative patient groups were the first to research and write "the first textbook on long COVID," as the Los Angeles Times put it.

    What they’ve taught us is a method for rethinking biomedicine more broadly and pursuing cures across all diseases.

    Reinventing medicine, with patients at the center
    In short, we may need an entirely new paradigm for how we think about medicine.

    The idea of a "paradigm shift" was coined by philosopher Thomas Kuhn, in his book, The Structure of Scientific Revolutions. At inflection points in history, new ways of gathering or processing or even thinking about data radically rewrite the rules of the scientific enterprise itself.

    New technology has spurred breathtaking new revolutions from the Human Genome Project, advances in supercomputing and big data, blockchain and Web 3.0, and most recently the blossoming possibilities of generative AI. Patients are likewise empowered in ways never seen in human history: we can use social media to form support groups across the globe while ill in bed, we can build our own patient registries to partner with research labs, and can generate our own data through smart watches, Oura rings, or other wearable devices. And new platforms even enable us to organize our own clinical trials.

    All these changes add up to the full coming-of-age for precision medicine. This personalized approach is becoming more accessible to every man, woman, and child, with costs falling exponentially, and access to these technologies available through the iPhone in your pocket.

    This new paradigm can and should be a patient-centered paradigm.

    From a different vantage point, that was also the message from Psychology Today editor-at-large Hara Marano, after she wrote a harrowing feature story delving into the depths of physician burnout, and how it was leading higher rates of suicide among people who had dedicated their lives to health care.

    But in their own way, the healers are hurting as much as the sick. Doctors allocate their time into 15-minute appointments, becoming cogs in a machine meant to fully optimize bureaucratic “relative value units” rather than to connect with a fellow human being in need. Constrained by the system, this leads to what’s called "moral injury." That’s when an individual is compelled to respond to or witness a system that runs contrary to their own ethical beliefs.

    Studies from the American Medical Association show that 80 percent of physicians report burnout, and suicide rates among doctors outpace those in the general population. In short, a failure to embrace this more human-centered frame puts not just patients’ lives at risk, but physicians' lives as well.

    But most importantly, forging a more humane way of thinking for doctors and patients can liberate all of us.

    Welcome to the Revolution
    In this new column, "Patient Revolution," I'll be chronicling these stories at the front lines of science and democracy. It's a breathtaking time to be alive, to be a science writer, and to have a foothold in helping forge the next generation of policies that can improve the lives of potentially billions of people around the world.

    I'm excited to share the first volley of stories: in the coming weeks, I'll delve more into the movement to treat long COVID, the tales of those who laid the groundwork for the patient-led movement, and the stories of communities who are forging the new paradigm in medicine.

    The human need is being met by patient entrepreneurs with long COVID who are creating new apps to track and manage symptoms, generating bottom-up solutions with patients rightfully claiming the mantle of true expertise. We'll explore how the Biden administration's new long COVID health report lays out a roadmap to use long COVID as a catalyst to roll out human-centered design principles across the health care system.

    COVID long-haulers are just the latest example of how patients have harnessed emerging technologies to take back their own agency in medicine. I'll take you into some seminal experiences over the past decade through the Stanford Medicine X community with dozens of "ePatient Scholars"—such as a philosopher with brain cancer and a quadriplegic artist with multiple sclerosis—all challenged the health system to be better. I'll also peel back the curtain on my own creative process: I chronicled patients’ quest to change health care forever in my book The Long Haul. But it’s often not enough to just be a journalist covering the story. Stories cry out for action, and should compel us to roll our sleeves up to be part of the solution. I want every would-be creator to make their writing or art part of their own vision for their own future success or for inaugurating a better world.

    These stories are constantly unfolding, across disease and discipline and demographic. The Wall Street Journal's Amy Dockser Marcus recently published the book We The Scientists, illustrating how families with children afflicted by the rare and deadly Niemann-Pick disease organized clinical trials to race toward a cure. Those families were pursuing their game-changing work, just as Brian Wallach, an alum of the Obama '08 campaign, was being diagnosed with ALS, the same terminal disease that felled baseball great Lou Gehrig and physicist Stephen Hawking. Determined to change that trajectory for himself and thousands of future patients, Wallach decided to tackle his medical care like a presidential campaign, galvanizing ALS advocates and leading toward a landmark $100 million bill signed into law that could transform ALS treatments. As Politico put it in a headline, "He was given six months to live. Then he changed DC." I believe that these sorts of moments can become the norm, rather than the exception.

    At every step, this patient-led innovation requires relentless optimism, constant drive, and an unyielding audacity to change our own lives.

    "If you hang out with the cowboys and the rebels and the pioneers, you will see the future faster," says Susannah Fox, a former chief technology officer for the U.S. Department of Health and Human Services, and the author of an upcoming book called Rebel Health.

    Come hang out with me. And let's go see the future together.

  • The End of Sex?
    How technology will change the way we have children.
    Reviewed by Tyler Woods

    KEY POINTS-
    Few people realize just how powerful embryo selection will become in the near future.
    Over the past two decades, the human genome has been decoded, and genetic testing has become ubiquitous.
    We will still have sex. And we will still have children. But the link between the two will grow more tenuous.

    Sex is fun because people who found it boring died without descendants.

    But the link between having sex and having kids has been severed since the sexual revolution of the late 1960s. Cheap contraception allowed women to decide when to have children. Social norms also changed—abortion became easier to access in case contraception failed.

    Whatever you think of these developments, contraception and abortion have led many people see sex as an activity we do for pleasure (or for bonding between couples), and having kids as an active choice to create a life.

    Not long after the pill enabled the sexual revolution, a new technology emerged that allowed gay and infertile couples, as well as single people, to have children: in vitro fertilization. IVF is a simple medical procedure that extracts eggs from women and combines them with sperm from men to create embryos. Couples can then decide which of the embryos to implant.

    While IVF was considered controversial at first, as soon as it proved viable in England and the U.S., attitudes quickly changed from skepticism to acceptance. In Japan, for example, about 5 percent of all births now come from IVF. In Denmark, the number is 10 percent, though that is partly because Denmark is a popular destination for women seeking sperm donors and fertility treatments.

    Since couples using IVF usually produce several embryos, and sometimes dozens, it is commonplace to use a simple genetic test to determine whether any of those embryos have “aneuploidy.” Aneuploidy occurs when an embryo has too few or too many chromosomes. The most common version of aneuploidy results in Down syndrome, and it is no surprise that couples will generally pick an embryo without chromosomal abnormalities when given the choice.

    Polygenic prediction
    Over the past two decades, the human genome has been decoded, and genetic testing has become ubiquitous. People get genetic tests to reveal their ancestry, to predict disease susceptibility, or to find out who the biological father of a child is in contested cases.

    But a new kind of genetic testing has entered the fertility clinic. Preimplantation Genetic Testing (PGT) can now be done not only for aneuploidy, or for monogenic traits such as Tay-Sachs disease; it can also be done for polygenic traits which involve many genetic variants, each of which has a small effect. Most of the traits we care about—ranging from height and weight, to cancer or schizophrenia—are highly polygenic.

    A few companies already offer polygenic risk scores that predict the likelihood that an embryo will develop a specific disease like diabetes. It is inevitable that some will apply these tests in ways that enable couples to select for aesthetic and cognitive traits. The more embryos couples can produce, the greater genetic variability there will be from which couples can choose. Mate choice will constrain the possibilities, but more embryos means more options.

    It is important to distinguish embryo selection using polygenic risk scores from gene editing. Selecting one embryo from a set of embryos is as old as IVF. It can be done at random, or it can be guided using polygenic scores. Embryo selection using polygenic scores is very different from gene editing since it involves selecting among whole embryos.

    Gene editing is still too dangerous to use on embryos, since it frequently produces off-target mutations that can have harmful effects on a developing fetus. It is possible that at some point in the future, CRISPR, the most common genetic editing techinique, will be used to “spell check” the genome, and maybe even rewrite it in fundamental ways, but we are a long way from that possibility. Few people realize, however, just how powerful embryo selection will become in the near future.

    In vitro gametogenesis
    IVF will become more potent as our understanding of genetics improves. And IVF will likely become more common as people around the world delay reproduction longer. Having children later raises the chances of infertility, but it also increases the risks to children since older parents pass along more de novo mutations. This means more couples will either need to use IVF to have children, or will use IVF electively in order to minimize disease risks to the children they have.

    Polygenic risk scores will become more accurate as the data from genome-wide association studies accumulates. But the game-changer right around the corner is in vitro gametogenesis (IVG). IVG allows scientists to take an adult cell, such as blood or skin cell, and turn it into a pluripotent stem cell (the kind that can become any cell, including a sperm or egg cell).

    When IVG becomes a reality for people (it’s already been done for animals), menopause and mutation accumulation will become less important, and couples will be able to create many embryos from which to select without the need for IVF. This means that the genetic variety of a couple’s embryos will be large enough that two short people could select a tall child, or two people at high risk of diabetes or schizophrenia will likely be able to select an embryo at low risk for both.

    We will still have sex. And we will still have children. But the link between the two will grow more tenuous. The prospect of artificial wombs is likely to increase this gap even more. An obvious risk is that both sex and babies will be thought of in more instrumental and less romantic terms. An obvious benefit is that our children will have lower risks of disease.

    In a series of forthcoming posts I’ll tackle some of the moral questions raised by these new technologies. I also hope to explore how these technologies will alter the way we live.

We will still have sex. And we will still have children. But the link between the two will grow more tenuous. The prospect of artificial wombs is likely to increase this gap even more. An obvious risk is that both sex and babies will be thought of in more instrumental and less romantic terms. An obvious benefit is that our children will have lower risks of disease. In a series of forthcoming posts I’ll tackle some of the moral questions raised by these new technologies. I also hope to explore how these technologies will alter the way we live.
