30 Million People Are Uninsured. New Startup Wants to Connect Them Directly to Doctors.

A child visits the doctor for a checkup.
When Eli Hall was in his thirties, he had a kidney stone that needed surgery. Despite having medical insurance, his out-of-pocket costs for the procedure came to $4,000.
Mira promises that most routine visits will cost around $99 or slightly above.
Hall, an Arizona-based small business owner soon discovered that such costs were proving to be the norm. As a result, he stopped buying insurance altogether. Now he pays in to a subscription-based model of healthcare where $300 per month will get him, his wife, and two children unlimited access (either over the phone or through in-office visits) to doctors in the Redirect Health network. This subscription also meets the Affordable Care Act insurance mandate.
Hall's move away from the traditional insurance care model might have been deliberate, but not everyone is as lucky. In 2018, the Centers for Disease Control and Prevention reported that 30.1 million people under the age of 65 were uninsured in the United States. Now, a new startup called TalktoMira is helping those without insurance access doctors for routine visits — affordably.
The service, accessed through the website (or phone or text), evaluates a user's symptoms and returns recommendations for specific doctors that factor in wait times, traffic conditions, and pricing. Khang T. Vuong, the founder and CEO, expects that doctors will be willing to provide discounts through this model, as they're eliminating the administrative costs associated with the insurance middleman. Some discounts can be as high as 50 percent, according to the website.
Mira promises that most routine visits will cost around $99 or slightly above. "This provides people who can't afford paying $3,000 to $4,000 per year in insurance premiums an alternative to access basic healthcare," Vuong says.
As of press time, Mira is available in the Washington D.C., Northern Virginia, and Dallas, and will soon expand across the country via a partnership with a national network of healthcare providers.
"For those who live in places where we don't have a presence, users can still search for the nearest and least busy urgent cares. The goal is to build a national database of walk-in clinics with straightforward upfront pricing so the 30 million uninsured and 56 million underinsured have access to same or next day primary care at an upfront affordable cost," Vuong says.
Getting Around Traditional Insurance
Mira caters to the uninsured by helping them navigate the healthcare system the moment they need it. "Currently cash patients have to rely mainly on Google for searching for options," Vuong says, adding that patients do also occasionally work with the app ZocDoc for booking. "However [ZocDoc] info has no pricing information; we fill in that much-needed gap," Vuong says. In focus groups TalktoMira conducted, a majority (70 percent) reported cost of service as their main barrier to healthcare.
As Hall's subscription-based model proves, cash-driven access like TalktoMira is not the only option for the uninsured. Direct primary care like the kind that Redirect Health delivers is another way to get around high premiums. It does so by effectively eliminating the administrative costs associated with the middleman, says David Slepak, the director of business development at Redirect. Doctors who are tired of packed schedules and the administrative headaches involved with the insurance model are only too happy to be a part of subscription or cash-based models, explains Vuong.
But TalktoMira and direct primary care models don't resolve the challenges of insurance related to catastrophic events.
James Corbett, Principal at Initium Health, points out the uninsured can also access federally qualified health centers across the country or a free clinic, but these might have problems of long wait times.
"Not a Cure-All"
TalktoMira might not provide the same level of consistency that seeing a primary care doctor does, though Vuong says there are ways to see the same doctor again by choosing them through the system. He adds that TalkToMira also empowers patients by asking them about their satisfaction after the visit and to see if any further checkups might be warranted, thus enabling patients to rate their doctors just like they would any other service provider.
"I might not have one primary care doctor, but I have the entire system behind me," says Hall.
But TalktoMira and direct primary care models don't resolve the challenges of insurance related to catastrophic events. The subscription model won't kick in if the patient has a heart attack and needs to be hospitalized, for example. So patients are also encouraged to purchase a high-deductible, low-premium plan for such contingencies.
"We're spending so much on insurance for the car that we can't afford the gas to drive the car."
Vuong recognizes TalktoMira doesn't solve all the problems related to insurance, but it can at least start by helping to facilitate access to routine visits. Even the insured don't always seek out a doctor because of copays and high deductibles, Slepak says. "We're spending so much on insurance for the car that we can't afford the gas to drive the car," he says.
TalktoMira is hoping that by making routine care accessible, it might both lessen the crunch in emergency rooms where many people don't really belong, and also nip problems in the bud.
"It's not a cure-all, not a panacea," admits Vuong. "It won't get you a knee replacement. But at least I can get you in the system so you might not have to get to that point."
A newly discovered brain cell may lead to new treatments for cognitive disorders
Swiss researchers have found a type of brain cell that appears to be a hybrid of the two other main types — and it could lead to new treatments for brain disorders.
Swiss researchers have discovered a third type of brain cell that appears to be a hybrid of the two other primary types — and it could lead to new treatments for many brain disorders.
The challenge: Most of the cells in the brain are either neurons or glial cells. While neurons use electrical and chemical signals to send messages to one another across small gaps called synapses, glial cells exist to support and protect neurons.
Astrocytes are a type of glial cell found near synapses. This close proximity to the place where brain signals are sent and received has led researchers to suspect that astrocytes might play an active role in the transmission of information inside the brain — a.k.a. “neurotransmission” — but no one has been able to prove the theory.
A new brain cell: Researchers at the Wyss Center for Bio and Neuroengineering and the University of Lausanne believe they’ve definitively proven that some astrocytes do actively participate in neurotransmission, making them a sort of hybrid of neurons and glial cells.
According to the researchers, this third type of brain cell, which they call a “glutamatergic astrocyte,” could offer a way to treat Alzheimer’s, Parkinson’s, and other disorders of the nervous system.
“Its discovery opens up immense research prospects,” said study co-director Andrea Volterra.
The study: Neurotransmission starts with a neuron releasing a chemical called a neurotransmitter, so the first thing the researchers did in their study was look at whether astrocytes can release the main neurotransmitter used by neurons: glutamate.
By analyzing astrocytes taken from the brains of mice, they discovered that certain astrocytes in the brain’s hippocampus did include the “molecular machinery” needed to excrete glutamate. They found evidence of the same machinery when they looked at datasets of human glial cells.
Finally, to demonstrate that these hybrid cells are actually playing a role in brain signaling, the researchers suppressed their ability to secrete glutamate in the brains of mice. This caused the rodents to experience memory problems.
“Our next studies will explore the potential protective role of this type of cell against memory impairment in Alzheimer’s disease, as well as its role in other regions and pathologies than those explored here,” said Andrea Volterra, University of Lausanne.
But why? The researchers aren’t sure why the brain needs glutamatergic astrocytes when it already has neurons, but Volterra suspects the hybrid brain cells may help with the distribution of signals — a single astrocyte can be in contact with thousands of synapses.
“Often, we have neuronal information that needs to spread to larger ensembles, and neurons are not very good for the coordination of this,” researcher Ludovic Telley told New Scientist.
Looking ahead: More research is needed to see how the new brain cell functions in people, but the discovery that it plays a role in memory in mice suggests it might be a worthwhile target for Alzheimer’s disease treatments.
The researchers also found evidence during their study that the cell might play a role in brain circuits linked to seizures and voluntary movements, meaning it’s also a new lead in the hunt for better epilepsy and Parkinson’s treatments.
“Our next studies will explore the potential protective role of this type of cell against memory impairment in Alzheimer’s disease, as well as its role in other regions and pathologies than those explored here,” said Volterra.
Scientists implant brain cells to counter Parkinson's disease
In a recent research trial, patients with Parkinson's disease reported that their symptoms had improved after stem cells were implanted into their brains. Martin Taylor, far right, was diagnosed at age 32.
Martin Taylor was only 32 when he was diagnosed with Parkinson's, a disease that causes tremors, stiff muscles and slow physical movement - symptoms that steadily get worse as time goes on.
“It's horrible having Parkinson's,” says Taylor, a data analyst, now 41. “It limits my ability to be the dad and husband that I want to be in many cruel and debilitating ways.”
Today, more than 10 million people worldwide live with Parkinson's. Most are diagnosed when they're considerably older than Taylor, after age 60. Although recent research has called into question certain aspects of the disease’s origins, Parkinson’s eventually kills the nerve cells in the brain that produce dopamine, a signaling chemical that carries messages around the body to control movement. Many patients have lost 60 to 80 percent of these cells by the time they are diagnosed.
For years, there's been little improvement in the standard treatment. Patients are typically given the drug levodopa, a chemical that's absorbed by the brain’s nerve cells, or neurons, and converted into dopamine. This drug addresses the symptoms but has no impact on the course of the disease as patients continue to lose dopamine producing neurons. Eventually, the treatment stops working effectively.
BlueRock Therapeutics, a cell therapy company based in Massachusetts, is taking a different approach by focusing on the use of stem cells, which can divide into and generate new specialized cells. The company makes the dopamine-producing cells that patients have lost and inserts these cells into patients' brains. “We have a disease with a high unmet need,” says Ahmed Enayetallah, the senior vice president and head of development at BlueRock. “We know [which] cells…are lost to the disease, and we can make them. So it really came together to use stem cells in Parkinson's.”
In a phase 1 research trial announced late last month, patients reported that their symptoms had improved after a year of treatment. Brain scans also showed an increased number of neurons generating dopamine in patients’ brains.
Increases in dopamine signals
The recent phase 1 trial focused on deploying BlueRock’s cell therapy, called bemdaneprocel, to treat 12 patients suffering from Parkinson’s. The team developed the new nerve cells and implanted them into specific locations on each side of the patient's brain through two small holes in the skull made by a neurosurgeon. “We implant cells into the places in the brain where we think they have the potential to reform the neural networks that are lost to Parkinson's disease,” Enayetallah says. The goal is to restore motor function to patients over the long-term.
Five patients were given a relatively low dose of cells while seven got higher doses. Specialized brain scans showed evidence that the transplanted cells had survived, increasing the overall number of dopamine producing cells. The team compared the baseline number of these cells before surgery to the levels one year later. “The scans tell us there is evidence of increased dopamine signals in the part of the brain affected by Parkinson's,” Enayetallah says. “Normally you’d expect the signal to go down in untreated Parkinson’s patients.”
"I think it has a real chance to reverse motor symptoms, essentially replacing a missing part," says Tilo Kunath, a professor of regenerative neurobiology at the University of Edinburgh.
The team also asked patients to use a specific type of home diary to log the times when symptoms were well controlled and when they prevented normal activity. After a year of treatment, patients taking the higher dose reported symptoms were under control for an average of 2.16 hours per day above their baselines. At the smaller dose, these improvements were significantly lower, 0.72 hours per day. The higher-dose patients reported a corresponding decrease in the amount of time when symptoms were uncontrolled, by an average of 1.91 hours, compared to 0.75 hours for the lower dose. The trial was safe, and patients tolerated the year of immunosuppression needed to make sure their bodies could handle the foreign cells.
Claire Bale, the associate director of research at Parkinson's U.K., sees the promise of BlueRock's approach, while noting the need for more research on a possible placebo effect. The trial participants knew they were getting the active treatment, and placebo effects are known to be a potential factor in Parkinson’s research. Even so, “The results indicate that this therapy produces improvements in symptoms for Parkinson's, which is very encouraging,” Bale says.
Tilo Kunath, a professor of regenerative neurobiology at the University of Edinburgh, also finds the results intriguing. “I think it's excellent,” he says. “I think it has a real chance to reverse motor symptoms, essentially replacing a missing part.” However, it could take time for this therapy to become widely available, Kunath says, and patients in the late stages of the disease may not benefit as much. “Data from cell transplantation with fetal tissue in the 1980s and 90s show that cells did not survive well and release dopamine in these [late-stage] patients.”
Searching for the right approach
There's a long history of using cell therapy as a treatment for Parkinson's. About four decades ago, scientists at the University of Lund in Sweden developed a method in which they transferred parts of fetal brain tissue to patients with Parkinson's so that their nerve cells would produce dopamine. Many benefited, and some were able to stop their medication. However, the use of fetal tissue was highly controversial at that time, and the tissues were difficult to obtain. Later trials in the U.S. showed that people benefited only if a significant amount of the tissue was used, and several patients experienced side effects. Eventually, the work lost momentum.
“Like many in the community, I'm aware of the long history of cell therapy,” says Taylor, the patient living with Parkinson's. “They've long had that cure over the horizon.”
In 2000, Lorenz Studer led a team at the Memorial Sloan Kettering Centre, in New York, to find the chemical signals needed to get stem cells to differentiate into cells that release dopamine. Back then, the team managed to make cells that produced some dopamine, but they led to only limited improvements in animals. About a decade later, in 2011, Studer and his team found the specific signals needed to guide embryonic cells to become the right kind of dopamine producing cells. Their experiments in mice, rats and monkeys showed that their implanted cells had a significant impact, restoring lost movement.
Studer then co-founded BlueRock Therapeutics in 2016. Forming the most effective stem cells has been one of the biggest challenges, says Enayetallah, the BlueRock VP. “It's taken a lot of effort and investment to manufacture and make the cells at the right scale under the right conditions.” The team is now using cells that were first isolated in 1998 at the University of Wisconsin, a major advantage because they’re available in a virtually unlimited supply.
Other efforts underway
In the past several years, University of Lund researchers have begun to collaborate with the University of Cambridge on a project to use embryonic stem cells, similar to BlueRock’s approach. They began clinical trials this year.
A company in Japan called Sumitomo is using a different strategy; instead of stem cells from embryos, they’re reprogramming adults' blood or skin cells into induced pluripotent stem cells - meaning they can turn into any cell type - and then directing them into dopamine producing neurons. Although Sumitomo started clinical trials earlier than BlueRock, they haven’t yet revealed any results.
“It's a rapidly evolving field,” says Emma Lane, a pharmacologist at the University of Cardiff who researches clinical interventions for Parkinson’s. “But BlueRock’s trial is the first full phase 1 trial to report such positive findings with stem cell based therapies.” The company’s upcoming phase 2 research will be critical to show how effectively the therapy can improve disease symptoms, she added.
The cure over the horizon
BlueRock will continue to look at data from patients in the phase 1 trial to monitor the treatment’s effects over a two-year period. Meanwhile, the team is planning the phase 2 trial with more participants, including a placebo group.
For patients with Parkinson’s like Martin Taylor, the therapy offers some hope, though Taylor recognizes that more research is needed.

“Like many in the community, I'm aware of the long history of cell therapy,” he says. “They've long had that cure over the horizon.” His expectations are somewhat guarded, he says, but, “it's certainly positive to see…movement in the field again.”
"If we can demonstrate what we’re seeing today in a more robust study, that would be great,” Enayetallah says. “At the end of the day, we want to address that unmet need in a field that's been waiting for a long time.”
