Portable lab you plug into your phone can diagnose illnesses like coronavirus

Engineers with the University of Cincinnati have created a tiny portable lab that plugs into your phone, connecting it automatically to a doctor’s office through a custom app UC developed.
The lab the size of a credit card can diagnose infectious diseases such as coronavirus, malaria, HIV or Lyme disease or countless other health conditions like depression and anxiety.

The patient simply puts a single-use plastic lab chip into his or her mouth then plugs that into a slot in the box to test the saliva.
The device automatically transmits results to the patient’s doctor through a custom app UC created for nearly instant results.
UC professor Chong Ahn and his research team used the smartphone device to test for malaria. But the device could be used for smart point of care testing for countless chronic or infectious diseases or to measure hormones related to stress.
“Right now it takes several hours or even days to diagnose in a lab, even when people are showing symptoms. The disease can spread,” Ahn said.
The study was published in the Nature journal Microsystems & Nanoengineering.
His research team created a novel lab chip that uses natural capillary action, the tendency for a liquid to adhere to a surface, to draw a sample down two channels called a “microchannel capillary flow assay.” One channel mixes the sample with freeze-dried detection antibodies. The other contains a freeze-dried luminescent material to read the results when the split samples combine again on three sensors.
Ahn said the device is accurate, simple to use and inexpensive.
“The performance is comparable to laboratory tests. The cost is cheaper. And it’s user-friendly,” Ahn said. “We wanted to make it simple so anyone could use it without training or support.”
UC doctoral student Sthitodhi Ghosh, the study’s lead author, said the biggest advancement in the device is in the novel design of its tiny channels that naturally draw the sample through the sensor arrays using capillary flow. Ahn is Ghosh’s Ph.D. advisor.
“The entire test takes place on the chip automatically. You don’t have to do anything. This is the future of personal healthcare,” Ghosh said.
While the device has applications for diagnosing or monitoring viruses or other diseases, Ahn said he sees potential in the field of mental health, where doctors already utilize smartphones to help track the wellness of patients.

I was lucky to get post-23andMe genetic counseling. All should have that option

A year ago, I was shivering in the pre-op room at Cedars-Sinai Medical Center waiting to be wheeled into surgery for a mastectomy. What led me there was my spitting into a tube, like millions of others have done, and sending off my DNA to be analyzed.
The results shocked and devastated me. They showed I have a mutation in the BRCA1 gene that puts me at an incredibly high risk of developing breast and ovarian cancer. The mastectomy would reduce my chance of developing breast cancer from as high as 72% to almost nothing. A few months earlier, I had surgery to remove my ovaries.
As terrified as I was at that moment, I also felt incredibly lucky.
I was lucky that I had opted to take the test. I was lucky that the mutation I have, which is one of roughly 1,000 possible BRCA mutations, is one of the three that 23andMe tests for. Otherwise I might not have known about that mutation for years, possibly until after I had been diagnosed with cancer. And I was very lucky that once I got my results, I was able to quickly get genetic counseling from a professional.
Genetic tests are becoming increasingly routine. While their market growth has slowed recently (23andMe laid off 14% of its workforce in January), more than 26 million people have already taken such at-home tests. Like me, many of those people will get scary results.
Results like what I received from 23andMe can be difficult to understand. Although the online service offers plenty of tutorials and explainer videos, those don’t feel like enough when faced with a serious health situation. I still had many questions. Did the results mean I would definitely get cancer? Were there other parts of my DNA that were keeping me safe? What was my next step? Was surgery inevitable?
To answer these questions, I needed more than a tutorial. I needed a genetic counselor — a human being to hear my questions and give me guidance based on deep knowledge.
Fortunately, I was able to connect with a counselor just a few days after I received my 23andMe results. The first thing she told me was that I needed to take a second test to confirm the results, though she also gently let me know that the 23andMe test was FDA approved and the second test would most likely confirm its results.
While my doctors gave me medical advice about my options for surgery versus surveillance, my genetic counselor gave me much-needed support. She explained the science behind my mutation. (BRCA genes, I learned, actually repress tumors. When they mutate, tumors can grow more easily.) She walked me through what I could expect to hear from my different doctors and, maybe most importantly, she offered a sympathetic ear.
For most people, there’s a large gap between access to at-home genetic tests and access to genetic counseling. Anyone with a few extra dollars can order a test online and get their results fairly quickly. But finding someone to help interpret those results can be expensive when insurance doesn’t cover counseling. It can also take weeks to get an appointment and, in some communities, it may be impossible. There are only 5,000 certified genetic counselors in the U.S. That’s one for every 65,440 people. Many states, including Wyoming, Mississippi, and Vermont, have fewer than five genetic counselors for the entire state.
If the Bureau of Labor Statistics is right, that should start to change. It anticipates a growth rate of 27% for genetic counselors between 2018 and 2028, a faster rate than most industries. Some in the genetic counseling field put the growth rate closer to 80%.
But more genetic counselors won’t necessarily guarantee more access. Right now, Medicaid and Medicare pay for genetic testing and genetic counseling only when it is initially recommended by a physician currently caring for the patient.
That means if a physician recommends a genetic test and works with a genetic counselor to help interpret the results, Medicaid and Medicare will cover the cost. But if you take the 23andMe, Ancestry.com, or other direct-to-consumer test and then seek genetic counseling, you will be on the hook for the cost, which will likely amount to more than you paid for the test.
You could, of course, take the results to your doctor, who could then recommend further testing in order to get the genetic counseling part covered. But many doctors today feel unprepared to work with patients at high risk of genetic conditions and are not confident in their ability to interpret results of genetic testing. So as at-home genetic tests proliferate, patients are dropping into a deep knowledge chasm that could affect their physical and mental health as they struggle to understand how to deal with the results.
A bill currently making its way through Congress, the Access to Genetic Counselor Services Act of 2019 (H.R. 3235), could change that. If passed, the bill would pay for people who have concerns to see a genetic counselor without needing to wait for a referral from a doctor. That means someone who had questions about an at-home test result could reach out to a knowledgeable expert with the reassurance that the visit would be covered by insurance.
While some insurers already cover genetic counseling in certain circumstances, this bill (which would apply only to people on Medicare) would go a long way toward encouraging all insurers to cover it. In the long run, this can save insurance companies money. Having surgery last year meant that I don’t need an annual breast MRI, which is standard (and expensive) practice for people with BRCA1 mutations. I’m also now unlikely to get breast or ovarian cancer, which will save my insurance company hundreds of thousands of dollars down the road.
It’s time to close the gap between the genetic information that’s easily available to people and the genetic information that they really need. Genetic counselors are the key.

Renowned HIV Researcher Frank Plummer Dies Suddenly at 67

The University of Manitoba (UM) community and fellow clinicians and colleagues around the world are mourning the death of Francis (Frank) Plummer, MD, a widely known scientist, academic, and trailblazing HIV/AIDS researcher.
Plummer, 67, died in Nairobi, Kenya, on Tuesday, where he was celebrating the 40th anniversary of the Manitoba/Kenya research collaboration, according to the university. The BBC reports that he died of a heart attack.
The Canadian Broadcasting Corporation (CBC) reported that Plummer was a keynote speaker at the annual meeting of the University of Nairobi’s collaborative center for research and training in HIV/AIDS/STIs. The news organization reported that Plummer collapsed at the meeting and was pronounced dead at a hospital in Nairobi.
The University of Manitoba said that Plummer, an UM alumnus, was senior scientific advisor of the Public Health Agency of Canada, director general of the Centre for Infectious Disease Prevention and Control in Ottawa, and scientific director general of the National Microbiology Laboratory in Winnipeg.
“He was admired and regarded highly by academics and researchers around the world, and his legacy of seeking to develop an HIV vaccine remains one of the landmarks of infectious disease prevention,” David Barnard, UM president and vice-chancellor, said in a news release.
The BBC reported that Plummer was also recognized for his leadership during the Severe Acute Respiratory Syndrome (SARS), H1N1 flu, and Ebola epidemics.

“Out-of-the-Box Thinking”

Steffanie Strathdee, PhD, associate dean of Global Health Sciences in the department of medicine at the University of California San Diego, told Medscape Medical News he had a strong influence on her life.
“When I trained as an aspiring HIV epidemiologist in Canada, Frank Plummer was one of about four infectious disease epidemiologists who were experts on HIV. His work was an inspiration to me as I decided to specialize as an HIV epidemiologist. Frank was known for his inventive out-of-the-box thinking that inspired novel HIV prevention research, which included the hypothesis that there was a subset of female sex workers who remained uninfected despite being continuously exposed.”
According to the UM release, the research involving that group of women in Kenya was perhaps his most widely known scientific contribution.
“(Plummer) focused on their immune systems and genetics to identify the basis for this resistance, and the project provided vital new information for HIV vaccine and drug development. Today, global interventions and campaigns have been built on his work,” the university noted.
“As an epidemiologist, he never forgot that behind each data point, there was a person who had a story, and he was one of the few that took the time to listen,” Strathdee said.
The BBC also reported that Plummer “had recently spoken publicly about undergoing experimental brain surgery to treat alcoholism.”
Plummer praised the positive results of the procedure, deep brain stimulation.
“Dr Plummer said the surgery had given him a new lease on life after a series of health problems had forced him to confront his battle with alcohol addiction,” the BBC reported.
A former student and then colleague, Keith Fowke, PhD, head of medical microbiology and infectious diseases at UM, said in a statement to the university, “Frank’s work was highly innovative and saved hundreds of thousands of lives. He was an outstanding and world-class researcher who was a dear colleague, mentor and friend to many of us lucky enough to work with him, and beside him.”
Fowke told the CBC that the research partnership between the University of Manitoba and the University of Nairobi was established when there was little global awareness of HIV/AIDS. Through the partnership, Plummer’s team discovered that HIV could be passed on to women or to babies through breast milk.
“He helped to identify a lot of the key factors that are involved in HIV transmission in the early days,” Fowke said.
Among Plummer’s awards were the Order of Canada, one of the country’s highest honors, and the Canada Gairdner Wightman Award, which recognizes work that has had a significant impact on health outcomes in the developing world.

CDC begins shipping coronavirus tests to state and local health departments

Coronavirus tests developed by the Centers for Disease Control and Prevention (CDC) shipped Wednesday to U.S. and international laboratories, including those at state and local public health departments.
Health providers and health departments previously sent samples for testing to the CDC in Atlanta, Ga.
The distribution of the tests will enable departments to identify new cases with increased speed — the test can provide results in four hours.
“Our goal is early detection of new cases and to prevent further spread of the coronavirus,” said CDC Director Robert R. Redfield.
“Distribution of these diagnostic tests to state laboratories, U.S. government partners and more broadly to the global public health community will accelerate efforts to confront this evolving global public health challenge,” he continued.
About 400 test kits will be distributed domestically and internationally. Each kit can test about 700-800 patient samples. More kits will be produced and shipped in the future, the CDC said.
The number of coronavirus cases reached 12 this week after a positive diagnosis in Wisconsin.
More than 28,000 cases have been confirmed worldwide, mostly in China. About 216 cases have been confirmed in other countries.

Ex-HHS chief threatens to vote ‘no’ on surprise medical billing measure

Rep. Donna Shalala (D-Fla.), a former secretary of Health and Human Services, said Friday she plans to vote against a bipartisan measure to protect patients from surprise medical bills unless it is changed.
The comments from Shalala are a sign of the divisions within both parties over the legislation.
Shalala said she is worried the bill from House Education and Labor Committee Chairman Bobby Scott (D-Va.) and ranking member Virginia Foxx (R-N.C.) would harm hospitals in her district.
The bill is slated for a vote in committee next week, and Shalala indicated other lawmakers have concerns as well.
Protecting patients from getting massive bills when they go to the emergency room and one of the doctors is outside their insurance network is seen as a rare area of bipartisan action this year. But the effort has been slowed by an array of competing proposals and intense lobbying from doctors and hospitals, who worry it would lead to damaging cuts to their payments.
Shalala said that she instead supports a rival proposal, more favorable to doctors and hospitals, that House Ways and Means Committee Chairman Richard Neal (D-Mass.) and ranking member Kevin Brady (R-Texas) also unveiled on Friday.
Shalala said she will seek to amend the bill next week but hasn’t worked out the details of her amendment given that she was only just shown the legislation.
“I have problems with it because it’s not balanced,” Shalala said of the Education and Labor proposal. “What I mean by that is the insurance companies are the big winners, the hospitals in my district and their employees get hurt and they’re the largest employers in my district. I can’t support a bill that will hurt the hospital workers in my district.”
Asked to respond, a spokesperson for Scott said, “There is broad consensus around the approach the Committee proposed today both within the Committee, as well as with our colleagues in the House Energy and Commerce Committee, and Senate [Health, Education, Labor and Pensions] Committee.”
The main dispute is over how much the insurer will pay the doctor or hospital once the patient is taken out of the middle.
The Energy and Commerce and Education and Labor bills would both set the payment rate based on the median payment for that service in the geographic area, with the option of going to arbitration for some high-cost bills.
In contrast, the Ways and Means bill gives the decision on payment to an outside arbiter, an approach more favored by doctors and hospitals but that has drawn criticism from the AFL-CIO and the consumer group Families USA as doing less to lower health care costs.
Neal defended his bill on Friday by pointing to the importance of not angering hospitals. “We think that it’s a good foundation,” Neal said. “We think that it’s patients first. Everybody’s got big hospitals [in their districts].”
House Energy and Commerce Committee Chairman Frank Pallone Jr. (D-N.J.) said Friday he thinks he can work with Ways and Means, but wants to make sure the final bill saves taxpayers money and does not raise premiums.

China’s Hubei to cut costs for small firms to ease coronavirus burden

China’s Hubei province, the epicenter of a coronavirus outbreak, will offer subsidies and cut costs for small and medium-sized firms to help them cope with the impact of the epidemic, the local government said on Sunday.
It said it would pay 30% of electricity costs for small and medium-sized firms involved in medical supplies, and cut the prices of water and natural gas for other smaller enterprises.
It will also move to cut rent, environmental inspection fees and financing costs for small and medium-sized firms and grant tax exemptions if they have been hit hard by the coronavirus.
