Tackling the Opioid Crisis, One Post at a Time
The largest ever seizure of fentanyl in the United States – 254 pounds of the white powder, enough to kill 1 in 3 Americans by overdose – was found under a shipment of cucumbers recently.
A policing approach alone is insufficient to take on the opioid crisis.
Those types of stories barely make the headlines any more, in part because illicit drugs are no longer just handsold by drug dealers; these sales have gone online. The neighborhood dealer faces the same evolving environment as other retailers and may soon go the way of Sears.
But opioids themselves are not going away. I could make an opioid purchase online in about 30 seconds and have it sent to my door, says Joe Smyser. The epidemiologist and president of The Public Good Projects isn't bragging, he's simply stating a fact about the opioid crisis that has struck the United States. The U.S Drug Enforcement Agency, social media companies, and some foreign governments have undertaken massive efforts to shut down sites selling illegal drugs, and they have gotten very good at it, shuttering most within a day of their opening.
But it's a Whac-A-Mole situation in which new ones pop up as quickly as older ones are closed; they are promoted through hashtags, social media networks, and ubiquitous email spam to lure visitors to a website or call a WhatsApp number to make a purchase. The online disruption by law enforcement has become simply another cost of doing business for drug sellers. Fentanyl, and similar analogues created to evade detection and the law, are at the center of it. Small amounts can be mixed with other "safer" opioids to get a high, and the growth of online sales have all contributed to the surge of opioid-related deaths: about 17,500 in 2006; 47,600 in 2017; and a projected 82,000 a year by 2025.
All of this has occurred even while authorities have been cracking down on the prescribing of opioids, and prescription-related deaths have declined. Clearly a policing approach alone is insufficient to take on the opioid crisis.
Building the Tools
The Public Good Projects (PGP), a nonprofit organization founded by concerned experts, was set up to better understand public health issues in this new online environment and better shape responses. The first step is to understand what people are hearing and the language they are using by monitoring social media and other forms of public communications. "We're collecting data from every publicly available media source that we can get our hands on. It's broadcast television data, it's radio, it's print newspapers and magazines. And then it's online data; it's online video, social media, blogs, websites," Smyser explains.
The purpose was to better understand the opioid crisis and find out if there were differences between affected rural and urban populations.
"Then our job is to create queries, create searches of all of that data so that we find what is the information that Americans are exposed to about a topic, and then what … Americans [are] sharing amongst themselves about that same topic."
He says it's the same thing business has been doing for years to monitor their "brand health" and be prepared for possible negative issues that might arise about their products and services. He believes PGP is the first group to use those tools for public health.
Looking At Opioids
PGP's work on opioids started with a contract from the Substance Abuse and Mental Health Administration (SAMHSA) through the National Science Foundation. The purpose was simply to better understand the opioid crisis in the United States and in particular find out if there were differences between affected rural and urban populations. A team of data scientists, public health professionals, and cultural anthropologists needed several months to sort out and organize the algorithms from the sheer volume of data.
Drug use is particularly rich in slang, where a specific drug or way of using it can be referred to in multiple ways in different towns and social groups. Traditional media often uses clinical terms, Twitter shorthand, and all of that has to be structured and integrated "so that it isn't just spitting out data that is gobbledygook and of no use to anyone," says Smyser.
The data they gather is both cumulative and in real time, tabulated and visually represented in constantly morphing hashtag and word clouds where the color and size of the word indicates the source and volume of its use.

The visual presentation of data helps to understand what different groups are saying and how they are saying it. For example, compare the hashtag and word clouds. Younger people are more likely to use the hashtags of Twitter, while older people are more likely to use older forms of media, and that is reflected in their concerns and language in those clouds.

A Ping map shows the origin of messages, while a Spidey map shows the network of how messages are being forwarded and shared among people. These sets of data can be overlaid with zip code, census, and socioeconomic data to provide an even deeper sense of who is saying what. And when integrated together, they provide clues to topics and language that might best engage people in each niche.

Opioids Speak
One thing that quickly became apparent to PGP in monitoring the media is that "over half of the information that the American public is exposed to about opioids is a very distant policy debate," says Smyser.
It is political pronouncements in DC, the legal system going after pharmaceutical companies that promoted prescription opioids for pain relief (and more), or mandatory prison terms for offenders. Relatively little is about treatment, the impact on families and communities, and what people can do themselves. That is particularly important in light of another key finding: residents of "Trump-land," the rural areas that supported the president and are being ravaged by opioids, talk about the problem and solutions very differently from urban areas.
"In rural communities there is usually a huge emphasis on self-reliance, and we take care of each other; that's why we enjoy living here. We are a neighborhood, we come together and we fix our own problems," according to Smyser.
In contrast, urban communities tend to be more transient, less likely to live in multigenerational households and neighborhoods, and look to formal institutions rather than themselves for solutions. "The message that we're sending people is one where there is really no role whatsoever for self-efficacy...we're giving them nothing to do" to help solve the problem themselves, says Smyser. "In fact, I could argue it is reducing self-efficacy."

The opioid crisis is complex and improving the situation will be too. Smyser believes a top-down policing approach alone will not work; it is better to provide front-line public health officers at the state and local level with more and current intelligence so they can respond in their communities.
"I think that would be enormously impactful. But right now, we just don't have that service." SAMHSA declined multiple requests to discuss this project paid for with federal money. A spokesman concluded with: "That project occurred under the previous administration, and we did not have a direct relationship with PGP. As a result, I am unable to comment on the project."
The Milken Institute Center for Public Health, a think tank that is working to find solutions to the opioid epidemic, had an upbeat response. Director Sabrina Spitaletta said, "PGP's work to provide real-time data that monitors topics of high concern in public health has been very helpful to many of the front-line organizations working to combat this crisis."
Few things are more painful than a urinary tract infection (UTI). Common in men and women, these infections account for more than 8 million trips to the doctor each year and can cause an array of uncomfortable symptoms, from a burning feeling during urination to fever, vomiting, and chills. For an unlucky few, UTIs can be chronic—meaning that, despite treatment, they just keep coming back.
But new research, presented at the European Association of Urology (EAU) Congress in Paris this week, brings some hope to people who suffer from UTIs.
Clinicians from the Royal Berkshire Hospital presented the results of a long-term, nine-year clinical trial where 89 men and women who suffered from recurrent UTIs were given an oral vaccine called MV140, designed to prevent the infections. Every day for three months, the participants were given two sprays of the vaccine (flavored to taste like pineapple) and then followed over the course of nine years. Clinicians analyzed medical records and asked the study participants about symptoms to check whether any experienced UTIs or had any adverse reactions from taking the vaccine.
The results showed that across nine years, 48 of the participants (about 54%) remained completely infection-free. On average, the study participants remained infection free for 54.7 months—four and a half years.
“While we need to be pragmatic, this vaccine is a potential breakthrough in preventing UTIs and could offer a safe and effective alternative to conventional treatments,” said Gernot Bonita, Professor of Urology at the Alta Bro Medical Centre for Urology in Switzerland, who is also the EAU Chairman of Guidelines on Urological Infections.
The news comes as a relief not only for people who suffer chronic UTIs, but also to doctors who have seen an uptick in antibiotic-resistant UTIs in the past several years. Because UTIs usually require antibiotics, patients run the risk of developing a resistance to the antibiotics, making infections more difficult to treat. A preventative vaccine could mean less infections, less antibiotics, and less drug resistance overall.
“Many of our participants told us that having the vaccine restored their quality of life,” said Dr. Bob Yang, Consultant Urologist at the Royal Berkshire NHS Foundation Trust, who helped lead the research. “While we’re yet to look at the effect of this vaccine in different patient groups, this follow-up data suggests it could be a game-changer for UTI prevention if it’s offered widely, reducing the need for antibiotic treatments.”
MILESTONE: Doctors have transplanted a pig organ into a human for the first time in history
Surgeons at Massachusetts General Hospital made history last week when they successfully transplanted a pig kidney into a human patient for the first time ever.
The recipient was a 62-year-old man named Richard Slayman who had been living with end-stage kidney disease caused by diabetes. While Slayman had received a kidney transplant in 2018 from a human donor, his diabetes ultimately caused the kidney to fail less than five years after the transplant. Slayman had undergone dialysis ever since—a procedure that uses an artificial kidney to remove waste products from a person’s blood when the kidneys are unable to—but the dialysis frequently caused blood clots and other complications that landed him in the hospital multiple times.
As a last resort, Slayman’s kidney specialist suggested a transplant using a pig kidney provided by eGenesis, a pharmaceutical company based in Cambridge, Mass. The highly experimental surgery was made possible with the Food and Drug Administration’s “compassionate use” initiative, which allows patients with life-threatening medical conditions access to experimental treatments.
The new frontier of organ donation
Like Slayman, more than 100,000 people are currently on the national organ transplant waiting list, and roughly 17 people die every day waiting for an available organ. To make up for the shortage of human organs, scientists have been experimenting for the past several decades with using organs from animals such as pigs—a new field of medicine known as xenotransplantation. But putting an animal organ into a human body is much more complicated than it might appear, experts say.
“The human immune system reacts incredibly violently to a pig organ, much more so than a human organ,” said Dr. Joren Madsen, director of the Mass General Transplant Center. Even with immunosuppressant drugs that suppress the body’s ability to reject the transplant organ, Madsen said, a human body would reject an animal organ “within minutes.”
So scientists have had to use gene-editing technology to change the animal organs so that they would work inside a human body. The pig kidney in Slayman’s surgery, for instance, had been genetically altered using CRISPR-Cas9 technology to remove harmful pig genes and add human ones. The kidney was also edited to remove pig viruses that could potentially infect a human after transplant.
With CRISPR technology, scientists have been able to prove that interspecies organ transplants are not only possible, but may be able to successfully work long term, too. In the past several years, scientists were able to transplant a pig kidney into a monkey and have the monkey survive for more than two years. More recently, doctors have transplanted pig hearts into human beings—though each recipient of a pig heart only managed to live a couple of months after the transplant. In one of the patients, researchers noted evidence of a pig virus in the man’s heart that had not been identified before the surgery and could be a possible explanation for his heart failure.
So far, so good
Slayman and his medical team ultimately decided to pursue the surgery—and the risk paid off. When the pig organ started producing urine at the end of the four-hour surgery, the entire operating room erupted in applause.
Slayman is currently receiving an infusion of immunosuppressant drugs to prevent the kidney from being rejected, while his doctors monitor the kidney’s function with frequent ultrasounds. Slayman is reported to be “recovering well” at Massachusetts General Hospital and is expected to be discharged within the next several days.
