Tianeptine - A so-called supplement with dangerous consequences. Our #expert weighs in on 'gas station heroin' warnings
Since 2022, the U.S. Food and Drug Administration has been actively urging consumers to avoid purchasing or consuming tianeptine -- a synthetic drug commonly called "gas station heroin" that can mimic the actions of opioids like fentanyl. Now, the FDA is upping the urgency of it's warnings as vendors continue to market the drug as a so-called "dietary supplement." UConn's C. Michael White, a Distinguished Professor of Pharmacy Practice, spoke with The Conversation about the problem with tianeptine in a must-read Q-and-A: What is tianeptine and why is it risky? Tianeptine stimulates the same receptors as well-known opioids such as fentanyl, heroin and morphine. When these drugs make their way from the blood to the brain, they bind to the “mu” type opioid receptor that triggers the sought-after pain relief and euphoria of those drugs as well as the dangerous effects like slowed or stopped breathing. High doses of tianeptine can bring euphoric effects similar to heroin and can also bring about the dissociative effect – the perception of your mind being disconnected from your surroundings and body – that is reminiscent of ketamine, an anesthetic that has a role in treating post-traumatic stress disorder and depression but has also commonly been abused as a street drug. Products containing tianeptine are often called “legal high drugs” – sometimes dubbed “gas station drugs” – a term used for all non-FDA-approved synthetic drugs that are sold casually in gas stations, online and elsewhere. What are the major adverse effects that people can experience? Data from clinical trials, case reports and poison control centers shows that tianeptine commonly induces agitation. This is typically accompanied by a fast heart rate and high blood pressure, confusion, nightmares, drowsiness, dry mouth and nausea, among other conditions. The most serious adverse events are slowed or stopped breathing, coma, heart arrhythmia and death. When long-term users try to stop tianeptine use, they often experience withdrawal symptoms reminiscent of opioid withdrawal. Consumers need to be aware that products containing tianeptine may not adhere to good manufacturing practices. This means they could contain lead or have other heavy metal contamination or be contaminated by microorganisms such as salmonella or mold. They could also contain other drug ingredients that are not disclosed. Knowingly or unknowingly combining active ingredients can increase the risk of adverse events. Additionally, the amount of the active ingredient contained in the product can vary widely, even with the same manufacturer. So past use does not guarantee that using the same amount will provide the same effect. How are these drugs sold in the US if they are not FDA-approved? If a drug product is not FDA-approved for prescription or over-the-counter-use, it is the Drug Enforcement Agency that is responsible for controlling market access. Before the DEA can ban an active ingredient in a drug product, it must be designated Schedule I, meaning the drug has no legitimate medical purpose and has high abuse potential. Manufacturers do not have to alert the DEA before selling their products to U.S. citizens. This means the DEA must detect an issue, identify the products causing the issue, identify the active ingredients in the product in question and do a full scientific review before designating it as Schedule I. Tianeptine came to market masquerading as a dietary supplement in gas stations and smoke shops, even though it is a synthetic compound. Tianeptine is also sold online allegedly for research purposes and not for human consumption. Tianeptine is undergoing clinical trials for the treatment of pain and depression, but sellers do nothing to make this type of labeling clear to consumers or to restrict purchases to researchers. What can people do to protect themselves and their families? Non-FDA-approved products containing synthetic drugs are very risky to use and should be avoided. FDA-approved drugs are available by a prescription from a health professional or over the counter with active ingredients on an approved list. If someone in a gas station, smoke shop or over the internet touts the benefits of a non-FDA-approved drug product – for pain or anxiety relief, to increase energy or for a buzz – be aware. It could be dangerous the first time you use it, but using it successfully once also doesn’t mean the experience will be the same the next time, and continued use can cause addiction. If a product is being sold “not for human consumption” or “for research purposes only,” you are at a high risk if you take it. Before you take any dietary supplement, make sure you check the active ingredient to be sure that it is, in fact, a natural product and not a synthetic chemical. If someone you know has bags with unmarked powder, a product labeled for research use or not for human consumption, or tablets or capsules not in standard drug bottles, that is a sign of a potentially dangerous situation. Standard drug tests sold over the counter are not designed to pick up tianeptine. One of the main reasons that people use these alternative substances of abuse over regular opioids, cannabis or amphetamines is that they are much harder to detect through work- or at-home drug screens by parents, schools, employers, probation officers and so on. If the DEA is not responding to emerging threats quickly enough, individual states can also act to ban sales of dangerous active ingredients in products. As of January 2024, at least 12 states have banned the sale of tianeptine, according to the FDA, although people in those states can still illegally procure it from the internet. So contacting your state legislators could be a place to start exercising your power to help prevent the harms from these products. This is an important piece, and if you are looking to know about tianeptine and the threat it poses to consumers in America, then let us help. Dr. C. Michael White is an expert in the areas of comparative effectiveness and preventing adverse events from drugs, devices, dietary supplements, and illicit substances.

Double the Bugs - Two cicada broods are set to emerge this summer, and our expert can explain the significance
It's coming this summer -- and it'll be twice as big! Two broods of cicadas are set to emerge this year, an event that last occurred more than 200 years ago and now has scientists, bug watchers, and fans of the loud and noisy (yet harmless) insects buzzing with anticipation. Media coverage of this popular event put on by nature is also starting, and John R. Cooley, a cicada expert at UConn, offered his expertise on the impending emergence to MassLive: This summer, some will get a chance to witness a phenomenon rarer — and probably louder — than Halley’s comet. For the first time in more than two centuries, two big groups of cicadas in the United States will emerge simultaneously from the ground. Cicadas, often called “heat bugs,” make their presence known throughout the country every summer by “singing” their loud song. But some of these large, flying insects only emerge from underground every so often, depending on their group, or brood. These “periodical” cicadas bury themselves in soil, where they spend most of their lives. This summer, millions of cicadas from broods XIX (emerging every 13 years) and XIII (every 17 years) will both crawl out from underground and fly across the south and Midwest looking for a mate, according to Cicadamania, a website dedicated to tracking the insects. The last time these two broods popped out of the ground at the same time was in 1803, Cicadamania reported – when the U.S. bought the Louisiana Territory from France. “You cannot possibly be unaware that periodical cicadas are out, because they’re out by the millions and millions, and they’re noisy, charismatic, active insects that are just everywhere,” John R. Cooley, an entomologist who studies cicadas at the University of Connecticut, told MassLive. “When you got them, you know it. And that’s what you can expect to see. That’s what any normal emergence looks like,” he continued. What folks will see are a whole lot of bugs that all look the same, as the ones that come out every decade-plus look the same as the ones that come out every year, Cooley said. Researchers are still exploring why some cicadas emerge periodically. One common theory is that their infrequent appearance helps them avoid predators and prevents enemies from synchronizing on their life cycle. But, Cooley said this theory is flawed since all cicadas have predators, but fewer than 10 species are periodical. Some of the cicada’s natural enemies include birds, moles and Cicada killer wasps, according to the University of California Integrated Pest Management Program. Another theory suggests the last ice age forced cicadas to evolve to have longer periodical life cycles. But, that theory is limited as many cicadas live near glacial areas – few of which are periodical, according to nature.com. “Science isn’t all about having the explanations,” Cooley said. “We just test hypotheses and there are a lot of hypotheses as to why these cicadas are the way they are, but none really stand up so far.” The emerging of cicadas is always a popular and trending topic, and if you have questions or are looking to cover, then let us help.

#Expert Insight: Here’s what can happen when dollar stores move in
Dollar stores - they're everywhere and on of America's fastest growing retail options. From the outside looking in, the idea of dollar stores seem like a win/win all around -- cheaper food, cheaper toys, and just about cheaper everything on offer to consumers looking to save money. However, recent research by UConn Professor Rigoberto Lopez might be pulling back the curtain on the bad deal these new outlets are selling to consumers and communities. Dollar stores have proliferated in recent years, and a study by a University of Connecticut economist has found that they contribute to less healthful food choices in the neighborhoods where they open. That’s because independent grocery stores tend to close in the same areas where the dollar stores open, according to professor Rigoberto Lopez, whose research focuses on agricultural economics. “The dollar store expanding is the fastest-growing retail format, and we also have seen a lot of family, independently owned grocery stores going out of business,” Lopez said. “So we try to link the two and to find not just a statistical correlation, but also we find that indeed when the dollar store comes to the neighborhood these stores tend to go out of business as well.” The low-priced dollar store — primarily Dollar General, Family Dollar and its subsidiary, Dollar Tree — “is the most successful type of format that is proliferating all across the United States, especially in rural areas and food deserts, which are the more underserved areas,” Lopez said. According to the study, published in Applied Economic Perspectives and Policy, there were 35,000 dollar stores in the United States in 2019 and they were “among the few food retailers” that grew in revenue after the Great Recession of 2008-10, outperforming big box discounters and retail clubs. Between 2000 and 2019, dollar stores opening in a neighborhood resulted in a 5.7% drop in independent grocery store sales, a 3.7% decrease in employment and a 2.3% increase in the likelihood of the grocery stores closing, according to the research. The effects are three times more likely in rural than urban areas, the study found. The dollar stores tend not to offer fresh produce and meats, with foodstuffs being limited to canned and boxed goods. “In general they provide an unhealthier food assortment … and less services,” Lopez said. “They don’t have bakery, butchers, they don’t have a lot of these.” The article also discusses not just the economic aspects, but public health implications as well. Lopez said the dollar stores’ business model is “low prices, low cost, low quality. … But a lot of the food that they sell is not healthy. It’s processed foods that they can store. Keeping fresh food and vegetables costs money.” Dollar stores are not necessarily a negative, if there was not a grocery store in the area before, Lopez said. “Public health advocates, they’re against dollar stores, but a lot of people that visit the dollar store, they prefer to have a dollar store than not to have anything at all in some areas. … But in general … we find if they are driving some of the local businesses out, then that is the negative trend.” Food insecurity and the changing landscape of grocery stores are important topics, and if you have questions or are looking to cover, then let us help.

It's a fabulous fall - and our expert can explain why all those colors come out this time of year
Autumn has arrived. And as we all take time to welcome this wonderous palette that nature delivers year after year, those who are curious about all those colors are looking for answers. Why there are so many different shades, tints, and tones? What causes the colors to change? And where's the best place to find one of nature's finest displays of leaves? It's a topic that comes up every year, and recently Connecticut Public Radio connected with UConn's Bob Fahey to get some of the answers about autumn in New England. I ventured into a forest in northeastern Connecticut with two UConn tree experts. We met up at Horsebarn Hill, one of the best viewpoints in the state, surveying a rolling river valley showing off with fall colors. We see oaks just starting to turn red. Nearby hickories provide a dash of yellow – and, of course, the maples are already stealing the show, even on a cloudy day. Here’s what I found out: Our trees are diverse One reason the foliage is so good is simply due to the number of species we have. “We have a very diverse hardwood forest in this part of New England,” said Bob Fahey, an associate professor and forest ecologist at UConn. “We have both species that are more southern species and also some of the more northern species.” “In comparison to say, the Mid-Atlantic or other places that have lots of deciduous species, we have maples, which are just the best,” he said. “We also have a number of species that have nice yellow foliage,” he said. “Birches and beech. If you go a little bit farther south from here, mostly what you have is oaks. And oaks can have good fall foliage colors, but there are a lot of times they don't and they don't last for as long.” We have lots and lots of trees The diversity of species provides a diversity of color, said Tom Worthley, an associate extension professor and a forester at UConn. He asked me to remember the last time I flew over Connecticut. What did you see, he asked. Lots of trees, right? “Most of the ground is covered by a tree canopy,” Worthley said, noting that some estimates put that tree canopy cover at around 75% of the land area of the whole state. “Back where we were standing a few minutes ago, we had some cherry trees,” Worthley said, his eyes scanning the trees enveloping us. “There's a few remnant ash, there's some walnut around the edges here. And let's see, some hickory.” A walnut tree towers over us – and there are even some white pines. It’s that varied bioscape that sets New England forests apart. “Even in my two-acre forest behind my house, I have 22 different species of tree, which is more than some regions of the northern part of the U.S.,” Fahey said. Travel to the west, and what you’re likely to see are lots of evergreens and aspen trees. “Not that there aren't others, there are plenty of others, but not in the same abundance and not in the same kind of mix that we have around here,” Worthley said. Climate plays a role Across New England are rolling hills with microclimates that can contribute to vibrant fall colors. “You’ll see ... highly different color in different parts of the landscape, which has to do with temperature differences,” Fahey said. Combine that with Connecticut’s mix of southern and northern species and the colors here might not be as exciting and bright as what you would see in Vermont and New Hampshire, Fahey said. But our foliage season can sometimes last a little bit longer. One reason? Oaks. “We have so much more of that oak component,” Fahey said. “The oaks will hold their leaves until the end of October.” Moisture, temperature and the amount of daylight all contribute to how long it takes for a tree to shed its leaves. And, for each species, the calculation is different. “A tree makes an economic decision,” Worthley said. “It decides, ‘Well, it's costing more in energy to keep these leaves going than what they're producing for me and so it's time to shut them off.’” Why do leaves fall anyway? It’s when leaves are green that the most important work is happening, pulling carbon out of the atmosphere and giving us oxygen. And for that green color, we can thank the pigment chlorophyll. “The color that's in the leaves – is always there from the time the leaf is grown,” Worthley said. “As the growing season fades, the chlorophyll disappears,” he said. Then the other colors in the leaf can begin to show off. Pigments like anthocyanins (reds and purples) and carotenoids (yellows and oranges) peek out, tiny threads in an autumnal blanket transforming New England’s green forests into a richly colored landscape. The colors are out - but only for a limited time. If you're a journalist looking to know more about this topic before all the leaves fall, then let us help.

A dose of regulation mixed with free-market observation - What can Connecticut learn as the state enters the cannabis era?
It's only been since January, but the cannabis industry in Connecticut is already a hit among consumers. There was initial worry that the quick expansion of stores and dispensaries could potentially blunt the long-term success of the retail aspect of the product in the state, but according to UConn's Fred Carstensen concerns about the oversupply seen in neighboring states is not a worry. “It’ll take three to four years to see how the market develops,” said Carstensen, a professor at University of Connecticut and the director of the Connecticut Center for Economic Analysis. In an article that goes into great detail, Carsten told the Stamford Advocate about the many factors and influences that can impact what has been a volatile market in some states since legalization became the trend. And as the state government checks the expansion of Connecticut’s adult-use cannabis market, Carstensen said local governments do the same. He said it wouldn’t matter if Connecticut’s retail cannabis scene was over-licensed, under-licensed, or just right. “Every municipality has the right to say yea or nay (to retailers),” Carstensen said. But he said an estimated 69 cannabis retailers in the Nutmeg State’s pipeline will make the bigger picture clearer. “(Then) it's pretty much available to everybody on a relatively short-travel basis,” Carstensen said. “Then we'll actually know what the market is.” Regulation and observation will be key to measure the success or failure of the market. Carstensen said that as the Nutmeg State’s market matures, retailers will “pull that business back into Connecticut when we become more competitively priced.” Peake agreed that “as (more Connecticut retailers) open up, we can probably expect the vast majority of those folks to be buying cannabis in Connecticut.” And Carstensen said that as much as interstate cannabis purchases skew understanding Connecticut’s market, it also serves as a check on oversaturating the Nutmeg State’s cannabis economy... And, Carstensen said, if there were too many cannabis dispensaries, "the market will tell us." "They’ll close,” the economics professor said.

#Expert Research: Biodegradable ultrasound implant could improve brain tumour treatments
One of the challenges in treating certain types of brain cancer is the way that the blood-brain barrier prevents chemotherapy drugs from reaching the tumors they're meant to target. UConn's Thanh Nguyen, a biomedical and mechanical engineer, is developing new technology that could improve how we are able to treat brain tumors. He recently spoke with Physics World about this groundbreaking research: A new type of biodegradable ultrasound implant based on piezoelectric nanofibres could improve outcomes for patients with brain cancer. Researchers led by Thanh Nguyen from the the University of Connecticut’s department of mechanical engineering fabricated the devices from crystals of glycine, an amino acid found in the human body. Glycine is not only non-toxic and biodegradable, it is also highly piezoelectric, enabling the creation of a powerful ultrasound transducer that could help treat brain tumours. Brain tumours are particularly difficult to treat because the chemotherapy drugs that would be effective in tackling them are blocked from entering the brain by the blood–brain barrier (BBB). This barrier is a very tight junction of cells lining the blood vessel walls that prevents particles and large molecules from making their way through and damaging the brain. However, ultrasound can be safely used to temporarily alter the shape of the barrier cells such that chemotherapy drugs circulating in the bloodstream can pass through to the brain tissues. Currently, to achieve such BBB opening requires the use of multiple ultrasound transducers located outside the body, together with very high intensity ultrasound to enable penetration through the thick human skull bone. “That strong ultrasound can easily damage brain tissues and is not practical for multiple-time applications which are required to repeatedly deliver chemotherapeutics,” Nguyen tells Physics World. By contrast, the team’s new device would be implanted during the tumour removal surgery, and “can generate a powerful acoustic wave deep inside the brain tissues under a small supplied voltage to open the BBB”. The ultrasound would be triggered repeatedly as required to deliver the chemotherapy that kills off the residual cancer cells at tumour sites. After a set period of time following treatment the implant biodegrades, thereby eliminating the need for surgery to remove it. The research, reported in Science Advances, demonstrated that the team’s device used in conjunction with the chemotherapy drug paclitaxel significantly extended the lifetime of mice with glioblastomas (the most aggressive form of brain tumour) compared with mice receiving the drugs but no ultrasound treatment. This is fascinating research and if you are interesting in covering this topic, then let us help.
