Precision Medicine concept
Is the value of "personalized medicine" over-promised? Why is the quality of health care declining for many people despite the pace of innovation? Do patients and doctors have conflicting priorities? What is the best path forward?
"How do we generate evidence for value, which is what everyone is asking for?"
Some of the country's leading medical experts recently debated these questions at the prestigious annual Personalized Medicine Conference, held at Harvard Medical School in Boston, and LeapsMag was there to bring you the inside scoop.
Personalized Medicine: Is It Living Up to the Hype?
The buzzworthy phrase "personalized medicine" has been touted for years as the way of the future—customizing care to patients based on their predicted responses to treatments given their individual genetic profiles or other analyses. Since the initial sequencing of the human genome around fifteen years ago, the field of genomics has exploded as the costs have dramatically come down – from $2.7 billion to $1000 or less today. Given cheap access to such crucial information, the medical field has been eager to embrace an ultramodern world in which preventing illnesses is status quo, and treatments can be tailored for maximum effectiveness. But whether that world has finally arrived remains debatable.
"I've been portrayed as an advocate for genomics, because I'm excited about it," said Robert C. Green, Director of the Genomes2People Research Program at Harvard Medical School, the Broad Institute, and Brigham and Women's Hospital. He qualified his advocacy by saying that he tries to remain 'equipoised' or balanced in his opinions about the future of personalized medicine, and expressed skepticism about some aspects of its rapid commercialization.
"I have strong feelings about some of the [precision medicine] products that are rushing out to market in both the physician-mediated space and the consumer space," Green said, and challenged the value and sustainability of these products, such as their clinical utility and ability to help produce favorable health outcomes. He asked what most patients and providers want to know, which is, "What are the medical, behavioral, and economic outcomes? How do we generate evidence for value, which is what everyone is asking for?" He later questioned whether the use of 'sexy' and expensive diagnostic technologies is necessarily better than doing things the old-fashioned way. For instance, it is much easier and cheaper to ask a patient directly about their family history of disease, instead of spending thousands of dollars to obtain the same information with pricey diagnostic tests.
"Our mantra is to try to do data-driven health...to catch disease when it occurs early."
Michael Snyder, Professor & Chair of the Department of Genetics and Director of the Center for Genomics and Personalized Medicine at Stanford University, called himself more of an 'enthusiast' about precision medicine products like wearable devices that can digitally track vital signs, including heart rate and blood oxygen levels. "I'm certainly not equipoised," he said, adding, "Our mantra is to try to do data-driven health. We are using this to try to understand health and catch disease when it occurs early."
Snyder then shared his personal account about how his own wearable device alerted him to seek treatment while he was traveling in Norway. "My blood oxygen was low and my heart rate was high, so that told me something was up," he shared. After seeing a doctor, he discovered he was suffering from Lyme disease. He then shared other similar success stories about some of the patients in his department. Using wearable health sensors, he said, could significantly reduce health care costs: "$245 billion is spent every year on diabetes, and if we reduce that by ten percent we just saved $24 billion."

A Core Reality: Unresolved Societal Issues
Sandro Galea, Dean and Professor at Boston University's School of Public Health, coined himself as a 'skeptic' but also an 'enormous fan' of new technologies. He said, "I want to make sure that you all [the audience] have the best possible treatment for me when I get sick," but added, "In our rush and enthusiasm to embrace personalized and precision medicine approaches, we have done that at the peril of forgetting a lot of core realities."
"There's no one to pay for health care but all of us."
Galea stressed the need to first address certain difficult societal issues because failing to do so will deter precision medicine cures in the future. "Unless we pay attention to domestic violence, housing, racism, poor access to care, and poverty… we are all going to lose," he said. Then he quoted recent statistics about the country's growing gap in both health and wealth, which could potentially erode patient and provider interest in personalized medicine.
Thomas Miller, the founder and partner of a venture capital firm dedicated to advancing precision medicine, agreed with Galea and said that "there's no one to pay for health care but all of us." He recalled witnessing 'abuse' of diagnostic technologies that he had previously invested in. "They were often used as mechanisms to provide unnecessary care rather than appropriate care," he said. "The trend over my 30-year professional career has been that of sensitivity over specificity."
In other words: doctors rely too heavily on diagnostic tools that are sensitive enough to detect signs of a disease, but not accurate enough to confirm the presence of a specific disease. "You will always find that you're sick from something," Miller said. He lamented the counter-productivity and waste brought on by such 'abuse' and added, "That's money that could be used to address some of the problems that you [Galea] just talked about."
Do Patients and Providers Have Conflicting Priorities?
Distrust in the modern health care system is not new in the United States. That fact that medical errors were the third leading cause of death in 2016 may have fueled this mistrust even more. And the level of mistrust appears correlated with race; a recent survey of 118 adults between 18 to 75 years old showed that black respondents were less likely to trust their doctors than the non-Hispanic white respondents. The black respondents were also more concerned about personal privacy and potentially harmful hospital experimentation.
"The vast majority of physicians in this country are incentivized to keep you sick."
As if this context weren't troubling enough, some of the panelists suggested that health care providers and patients have misaligned goals, which may be financially driven.
For instance, Galea stated that health care is currently 'curative' even though that money is better spent on prevention versus cures. "The vast majority of physicians in this country are incentivized to keep you sick," he declared. "They are paid by sick patient visits. Hospital CEOs are paid by the number of sick people they have in their beds." He highlighted this issue as a national priority and mentioned some case studies showing that the behaviors of hospital CEOs quickly change when payment is based on the number of patients in beds versus the number of patients being kept out of the beds. Green lauded Galea's comment as "good sense."
Green also cautioned the audience about potential financial conflicts of interest held by proponents of precision medicine technologies. "Many of the people who are promoting genomics and personalized medicine are people who have financial interests in that arena," he warned. He emphasized that those who are perhaps curbing the over-enthusiasm do not have financial interests at stake.
What is the Best Path Forward for Personalized Medicine?
As useful as personalized medicine may be for selecting the best course of treatment, there is also the flip side: It can allow doctors to predict who will not respond well—and this painful reality must be acknowledged.
Miller argued, "We have a duty to call out therapies that won't work, that will not heal, that need to be avoided, and that will ultimately lead to you saying to a patient, 'There is nothing for you that will work.'"
Although that may sound harsh, it captures the essence of this emerging paradigm, which is to maximize health by using tailored methods that are based on comparative effectiveness, evidence of outcomes, and patient preferences. After all, as Miller pointed out, it wouldn't do much good to prescribe someone a regimen with little reason to think it might help.
For the hype around personalized medicine to be fully realized, Green concluded, "We have to prove to people that [the value of it] is true."
The process of finding the right gift for your favorite life science lover can be daunting. Here's a roundup of the coolest bio-products related to health, nutrition, gaming, lifestyle and more.
AYO Circadian Light Therapy Wearable
We don’t hear it tick, but we have our own clock inside our body–more precisely, circadian clocks. Our cells contain tiny molecular clocks that keep track of our circadian rhythms, or our sleep and metabolism pattern and activity levels, on a daily basis. Chronic circadian disruptions can lead to sleep disorders, poor energy levels, weight gain, lousy mood, and sped-up aging, as well as increased risk for every “modern” disease out there, from diabetes to cancer.
Now, high-tech glasses have been developed that attempt to mimic the benefits of sunlight. In the morning and afternoon, these glasses shed blue light into your eyes to stimulate the master clock at the base of your brain for less drowsiness. The technology's design draws from an area of research, chronobiology, that received a Nobel Prize in 2017 and has become increasingly active in recent years.
“We have been developing and testing the AYO Circadian Health solution for the past five years in collaboration with some of the world's leading experts and researchers in chronobiology, light therapy and health,” said Alexander Dimitrov, co-creator of AYO. “We have done studies with over 25,000 participants, and over one million light sessions,” Dimotrov continued, partnering with institutions such as Mount Sinai Hospital, City of Hope and the U.S. Department of Defense.
The technology could fundamentally reshape the way we view sleep, health and our daily calendars. And, when connecting to a mobile app, the glasses could minimize circadian disruptions for travelers between conflicting time zones.

myDNAge Test
It's not easy for many people to break free of their attachment to the concept of chronological age, which counts years by how many times we’ve circled the sun since the day we were born. Society lumps us all into one age bracket according to our date of birth but, lately, research is suggesting that we should do some serious deconditioning. According to these studies, the more accurate measure is your biological age, a measurement based on various biomarkers of the body’s overall health and resilience, regardless of your calendar age.
If you want to find out your “true” biological age, myDNAge is a test that focuses on epigenetics, or patterns of changes in DNA methylation, with some initial research pointing to its accuracy. It offers a snapshot of your epigenetic age as well as key biomarkers related to your metabolism, risk of Alzheimer's and more, according to Xiaojing Yang, group leader of epigenetics at myDNAge. “You can perform tests six to 12 months [apart] to track the impact of lifestyle changes,” Yang said. The kit could be a useful tool both for citizen scientists and biohacking veterans.

Prairie Sky Yak Cheese
Do you love cheese? Do you love exotic cheese? Do you have an interest in preserving biological and genetic diversity? If you answered yes to all three questions, yak cheese was made for you. This type of cheese typically comes from a free-range yak living 13,000 feet above surface level in the Tibetan Himalayas, a relative of the endangered Wild yak. (North America is home to at least 5,000 registered yaks.)
“When I learned that we had a piece of rare biodiversity to be preserved for future generations, I realized that the yak in North America needed a job,” said Nicole Geijer Porter, president of World Heritage Yak Conservancy (WHYC), an organization formed to protect heritage yak “If an animal cannot be beneficial to the rancher in some way, exclusively as pets and lawn ornaments, they will go extinct. Raised for meat they are often hybridized with cattle to grow bigger and faster, so they will also go extinct,” said Porter, an epigeneticist turned yak herder.
Each slice of cheese and piece of butter supports the genetic testing and tracking of Tibetan yak. (You can become a member of WHYC through the Adopt-A-Yak program). “This project is also of biological importance because of the low methane emission research on yak, and the high nutritional content of the milk and cheese,” said Porter.
As for flavor, the Prairie Sky Yak Gruyere is a semi-hard cheese with a nutty taste sometimes compared to chocolate; Tomme de Savoie is a semi-soft Alpine cheese reminiscent of a washed rind muenster; and the Yak Cheddar is made with yak milk following the classic English recipe from Wells Cathedral, with earthly and pungent flavors.
(Various prices; $59.95 for the Three Yak Cheese Flight Gift Box, $139.95 for the Regional Himalayan Yak Cheddar Gift Basket and more)
Bite Toothpaste Bits
The price of a healthy smile is steep. Each year over one billion plastic toothpaste tubes are thrown out, over 50 Empire State Buildings worth of these tubes end up in landfills or oceans, and many animals suffer and die each year in cruel tests for improving oral care in people.
Sustainable oral care is both an act of self-love and giving back to the environment. Bite is a toothpaste that boasts about its green practices for a reason: it uses recyclable glass bottles with aluminum lids that break down into sand after they’ve been used. For shipping, Bite uses kraft envelopes padded with recycled and compostable newspapers, and its boxes are made of fully recycled, corrugated cardboard and sealed with paper tape. Bite refills come in 100% home compostable pouches every four months (still no plastic).
Sustainability aside, there may be an element of fun to Bite – as you brush, a mint foam forms “like magic,” the company claims.
Fractional Laser Treatment for Skin
The environment is hard on our skin: from ultraviolet rays to pollution, a constant oxidative war is waged upon it, leading to loss of collagen and damage to the barrier function of the skin. A fractional laser treatment is a type of laser skin resurfacing procedure that essentially traumatizes the skin – in a good way - through subjecting a small area of it to tiny amounts of laser energy. The laser penetrates the second layer of skin, the dermis, leading to skin exfoliation, which stimulates collagen and elastin production.
The treatment may help with soothing acne scarring, correcting uneven skin tone and texture, and reducing wrinkles and fine lines, sun damage and age spots. Recent research suggests the fractional laser can help with improving skin elasticity and reducing the amount and depth of wrinkles, though there’s little to no evidence for any benefits for eyebags, dark circles, discolorations within the eye area and water retention.
(Typically, a single fractional laser treatment costs $750 for a small area, $1500 for a full facial treatment, and $2000 for full face.)
Gadgets and Apps to Measure Your Heart Rate Variability
Heart rate variability may sound like a condition that requires immediate medical treatment, but the more you have of it, the better for your health. Although you may think of the heart as a steadily beating metronome, there are actually small differences in the amount of time between each beat. These differences are called HRV, and having more HRV has been linked to better fitness and fewer diseases.
HRV is easy to measure with a range of gadgets on the market, including Fitbits and Oura Rings. Which product floats your boat is a matter of personal preference, but the Polar H10 chest strap offers some advantages. For example, you can measure your HRV with the Polar H10 while walking around, unlike some devices that require you to stay still while taking a reading.
Plus, the Polar sensor pairs with free apps such as Elite HRV that are great for tracking how your HRV changes over time. "HRV really helps you gauge if you're moving in a positive or negative direction" with your health, says Jason Moore, the CEO and founder of Elite HRV and Spren. Have fun experimenting over the holidays with different lifestyle habits that are associated with higher HRV, some studies show, such as intermittent fasting, regular exercise and just getting more sleep.
($89 for the Polar H10, $0 for the Elite HRV app)
FoodMarble AIRE2
Its predecessor, FOODMarble AIRE1 was a pocket-size breath-testing device that measured hydrogen on the breath. More hydrogen means less digestion, and the AIRE1 used advanced breathalyzer technology to figure out what exactly is going on with the gut. Now, the company has launched FoodMarble AIRE2, which also measures methane alongside with hydrogen. High levels of methane in the body may cause abdominal pain, bloating and constipation, cirrhosis of the liver and chronic pancreatitis. The AIRE2 also comes with haptic feedback to make it easier to use.
Research suggests that these breath tests are valid as at-home diagnostic tools for many digestive conditions. To get the most accurate results, though, it’s important to closely follow the recommended protocol - for example, you can’t eat or drink anything for 10 to 12 hours before the test.

NADI X Pants
Even if you’re a yoga zealot enjoying the benefits to your strength, balance and flexibility, chances are you're performing the movements sort of askew. Wearable technology wants to improve your yoga posture and these sleek yoga pants called NADI X have subtle electronic sensors that track how you place your hands, rotate your hips, and align your back. The leggings use haptic feedback (or vibrations on your skin) to slowly guide you into correct alignment. You can also combine the wearable with an app that contains 40 poses and fitting music. Even if you aren't into yoga, you could use the pants for a perfect stretching session. If you do use it for yoga poses, the pants will “speak” to you, letting out a soothing "om" sound once everything is perfect.
Meta Quest Pro VR headset
When it comes to perfecting virtual reality (VR), the Meta Quest Pro VR headset is one step ahead the rest. In a vibrant 3D virtual space, your Meta avatar has the ability to translate your real-life facial expressions into the virtual realm so the experience can feel more personal, while controllers track your movement and use haptic feedback to translate your hand gestures and finger actions into VR as well. Unlike its Quest 2 headset, Meta markets this Quest Pro headset, which was just released in October, as a great tool for work and business meetings, but you can also use it to play games, watch movies, or download fitness apps or mental-health related apps – some of which are designed to help you get boxing workouts with long-distance friends, fight your fear of heights or meditate in outer space.
Rouge Sur Mesure Custom Lip Color Creator
Beauty and artificial intelligence (AI) complement each other well in the new Yves Saint Laurent lip personalized color – which wants to put the final nail on the coffin of generic lipsticks. This is a lipstick printer at its core. You pair a device to your smartphone and then insert three lipstick cartridges into the base, each of which comes with a color palette (all four could create up to 4,000 lipstick shades). Particularly charming is the fact that you can take a photo of your outfit, and the app will suggest shades that match or clash it.
($299, cartridges $89 each)
Dairy-Free Cream Cheese and Meatless Breakfast Patties
On the environmental front again, meatless patties and dairy-free cream cheese constitute conscientious and delicious choices for vegans, vegetarians and pretty much anyone else. Chicago-based Nature's Fynd is worth checking out. It uses a microbe named Fusarium strain flavolapis, which has origins in an acidic hot spring at Yellowstone National Park.
“We use this remarkable microbe to grow Fy — a nutritional fungi protein that’s made into a wide variety of delicious and sustainable foods,” says Karuna Rawal, Nature’s Fynd CMO. Fy is grown via a breakthrough fermentation process using a fraction of the water, land, and energy compared to traditional protein sources.
It’s a sustainable way to grow food for Earth’s population,” but Nature’s Fynd isn’t just concentrating on Earth. The company recently partnered with NASA to send Fy to space. “As long as there’s an appropriately controlled environment, we can grow Fy anytime, anywhere. It could be a nutritious food source for astronauts on deep space missions," said Rawal.
CBD Oil
Biologically curious people may be especially interested in trying cannabinoid (CBD) oil. CBD is a natural and safe substance found in cannabis, which has been found to tackle anxiety and depression, reduce symptoms of post-traumatic stress disorder, help manage chronic pain and migraines, improve sleep patterns, and keep panic attacks at bay. Kanibi’s Isolate CBD Oil Tincture is a good choice as it is cinnamon-flavored and made in an FDA-inspected facility.

Govee RGBIC Floor Lamp
Another winner for anyone who's been hearing about the health benefits of obeying your circadian rhythms: "RGB" lights, or red-green-blue lights that can be operated by remote control to shine bright blue light during the day and then, with a few touches of your phone, bathe you in warmer, red light to get you ready for bed. Look for RGB bulbs to stick into the light fixtures you already have, or you could opt for the Govee floor lamp that syncs with an app on your phone (or Alexa) for circadian color changing. You can also put it on party mode and watch it shift across 16 million color shades in response to the rhythms and beats of Cuddle Up, Cozy Down Christmas and Hanukkah Oh Hanukkah.
($99)
PackPoint
If you suffer from packing anxiety (or incompetence), an app may take away the pain. PackPoint is an app that builds your packing list according to trip type, activities and weather. You add your trip details, select activities (fancy dinner, business meeting, or even workout are some examples), and PackPoint tells you what you need to bring to your destination. The app is free, but upgrading to Premium for a small fee lets you add your own activities and packing list items.
(Free, Premium Package $2.99)
Eternity Rose
Roses symbolize love, passion, innocence, friendship, and the disarming power of natural beauty. They wilt fast, though, and their spectacle is an unsettling reminder of the fragility of beauty and existence. Unless you dip the rose in 24 karat gold.
The Eternity Rose is put through an intricate three-month process of electroplating, or coating the rose with copper and then with other metals in micro-thin layers. You won’t have to see your flowers sag after a few days because these roses never die. The glitter of gold atop the natural rose (or platinum or silver–whatever you prefer) will fit right in with the Christmas Eve ambiance.
($169 for the gold rose)
