Medicare Pilot Program Will Use AI To Decide If Pain Treatments Are Worth the Cost

By Pat Anson

Medicare patients in six states who need epidural steroid injections, cervical fusions, spinal cord stimulators, arthroscopic knee surgery and other treatments for chronic pain will soon have their prior authorization requests reviewed by artificial intelligence (AI) to decide whether the treatments are worth the cost.

The Centers for Medicare & Medicaid Services (CMS) is launching a 6-year pilot program on January 1, 2026 called the Wasteful and Inappropriate Service Reduction Model --- known as “WISeR” for short.

WISeR will cover Original Medicare patients in New Jersey, Ohio, Oklahoma, Texas, Arizona, and Washington who seek treatment for chronic pain, impotence, incontinence, and burns or wounds needing skin and tissue substitutes.

WISeR will review over a dozen treatments that CMS considers low-value, potentially unsafe, or suspicious because of prior reports of fraud and wasteful spending. The low-value treatments alone cost Medicare nearly $6 billion in 2022.

“CMS is committed to crushing fraud, waste, and abuse, and the WISeR Model will help root out waste in Original Medicare,” CMS Administrator Dr. Mehmet Oz said in a press release. “Combining the speed of technology and the experienced clinicians, this new model helps bring Medicare into the 21st century by testing a streamlined prior authorization process, while protecting Medicare beneficiaries from being given unnecessary and often costly procedures.”

Under traditional or Original Medicare, most covered services do not require prior authorization, but Medicare Advantage (MA) plans often do. For that reason, CMS is partnering with private MA plans that have more experience using AI and other advanced technologies to process prior authorization requests. If a request is denied by WISeR, the agency says it will then be reviewed before a final decision “by licensed clinicians, not machines.”

CMS claims that WISeR will “expedite decision making” and not change coverage for traditional Medicare beneficiaries, who “retain the freedom to seek care from their provider or supplier of choice.”

Those providers, however, will be incentivized with higher Medicare payments if they participate in WISeR and show they can reduce the use of low value treatments and help lower Medicare spending.  

Pain treatments that will be reviewed under the WISeR Model include these procedures:

• Electrical Nerve Stimulation  

• Deep Brain Stimulation for Essential Tremor and Parkinson's Disease

• Vagus Nerve Stimulation

• Surgical Removal or Ablation of Nerves

• Epidural Steroid Injections (excluding facet joint injections)

• Percutaneous Vertebral Augmentation (PVA) for Vertebral Compression Fractures

• Cervical Fusions  

• Arthroscopic Surgery for Knee Osteoarthritis

• Percutaneous Image-Guided Lumbar Decompression for Spinal Stenosis

Many of these treatments have already drawn scrutiny for being ineffective or costly. Studies have found that spinal cord stimulation, for example, has no benefit for back pain; while epidural steroid injections, nerve blocks and nerve ablation have been found to have little or no benefit.

‘Perverse Incentives’

Not surprisingly, the WISeR Model has drawn criticism from physicians who perform the procedures, who decry the use of AI and algorithms to make healthcare decisions.

“We firmly believe that (WISeR) will jeopardize patient access to care, create more administrative burdens for physicians, offer perverse payment incentives for third-party vendors, and represent a substantial reversal of progress toward this Administration’s goal of prioritizing patients over paperwork,” a coalition of 23 neurosurgeon organizations wrote in a letter to Dr. Oz.

“Decision criteria to be used by participating vendors — including algorithms, scoring models, and evidence-based guidelines — remain a “black box,” leaving stakeholders with little to no insight into how prior authorization determinations will be made.”

Patient rights groups and some politicians say WISeR will create new roadblocks for Medicare patients needing treatment.

“While prior authorization is often described as a cost-containment strategy, in practice it increases provider burden, takes time away from patients, limits patients’ access to life-saving care, and creates unnecessary administrative burden,” Rep. Ami Bera (D) and Rep. Suzan DelBene (D) said in a recent letter to Dr. Oz.

“The use of prior authorization in Medicare Advantage shows us that, in practice, WISeR will likely limit beneficiaries’ access to care, increase burden on our already overburdened health care work force, and create perverse incentives to put profit over patients.”

About 12% of prior authorization denials by Medicare Advantage insurers were appealed in 2023, and more than 80% of them were overturned, according to the Center for Medicare Advocacy.

An HHS Inspector General's report in 2018 found “widespread and persistent” problems involving denials of care by Medicare Advantage. Another report in 2022 found 13% of denied requests actually met Medicare’s rules and should have been approved.

“(WISeR) is) a backdoor way of putting everybody in a Medicare Advantage plan,” Carrie Graham, executive director of the Medicare Policy Initiative told Cleveland.com. “It’s a first step to getting rid of, or downgrading, the freedom that traditional Medicare provides.”

Experimental Implant Could Dispense Drugs Inside Joints During Arthritis Flares

By Crystal Lindell

Researchers in the UK are developing an artificial cartilage that could dispense anti-inflammatory and pain relieving medications from within joints during an arthritis flare-up.

The gel-like material, developed by a team at the University of Cambridge, has been designed to respond to changes in pH, a measure of acidity. During flare-ups, arthritic joints become inflamed and slightly more acidic than the surrounding tissue.

As acidity increases, the polymer implant becomes softer and more jelly-like, triggering the release of drug molecules within the joint. In theory, researchers say the drugs would be released precisely where and when they are needed, providing more effective and continuous relief.

“These materials can ‘sense’ when something is wrong in the body and respond by delivering treatment right where it’s needed,” said Stephen O’Neill, PhD, a postdoctoral researcher at Cambridge. “This could reduce the need for repeated doses of drugs, while improving patient quality of life.”

The research was reported in the Journal of the American Chemical Society. 

The polymer material was developed by a research group in the Department of Chemistry at Cambridge that specializes in designing and building unique materials for a range of potential applications.

“For a while now, we’ve been interested in using these materials in joints, since their properties can mimic those of cartilage,” said lead author Oren Scherman, PhD, Director of the Melville Laboratory for Polymer Synthesis. “But to combine that with highly targeted drug delivery is a really exciting prospect.”

Clinical trials are needed before the material can be used in patients. Researchers say their next steps will be to test the materials in living organisms to evaluate their performance and safety. 

If successful, that could lead to a new generation of responsive biomaterials capable of treating a variety of chronic diseases. The gel could be adapted for placement in different parts of the body.

“It’s a highly flexible approach, so we could in theory incorporate both fast-acting and slow-acting drugs, and have a single treatment that lasts for days, weeks or even months,” said O’Neill.

While it is incredible to see these new advances in pain treatment, it’s also imperative that researchers make sure that they are actually better than the current treatments available. They also need to make sure that the implants are relatively easy to remove in the case of complications.

In the research paper, the authors suggest the implants could be used for rheumatoid and osteoarthritis pain. However, both of those diseases can cause widespread joint pain, so it remains unclear if material needs to be implanted in multiple joints to be effective.

And if the implants can be effective “for days, weeks or even months,” how would they be re-loaded with medication or even fully replaced? Such a process could be very taxing for patients, especially if it requires a trip to the hospital or a doctor’s office each time.

In the original Jurassic Park movie, the character Dr. Ian Malcolm says, “Your scientists were so preoccupied with whether they could, they didn't stop to think if they should.”

I hope these researchers heed that advice. 

Balancing the Risks and Benefits of Kratom

By David Kroll

David Bregger had never heard of kratom before his son, Daniel, 33, died in Denver in 2021 from using what he thought was a natural and safe remedy for anxiety.

By his father’s account, Daniel didn’t know that the herbal product could kill him. The product listed no ingredients or safe-dosing information on the label. And it had no warning that it should not be combined with other sedating drugs, such as the over-the-counter antihistamine diphenhydramine, which is the active ingredient in Benadryl and other sleep aids.

As the fourth anniversary of Daniel’s death approaches, a recently enacted Colorado law aims to prevent other families from experiencing the heartbreak shared by the Bregger family. Colorado Senate Bill 25-072, known as the Daniel Bregger Act, addresses what the state legislature calls the deceptive trade practices around the sale of concentrated kratom products artificially enriched with a chemical called 7-OH.

7-OH, known as 7-hydroxymitragynine, has also garnered national attention. On July 29, 2025, the U.S. Food and Drug Administration issued a warning that products containing 7-OH are potent opioids that can pose significant health risks and even death.

As kratom and its constituents are studied in greater detail, the Centers for Disease Control and Prevention and university researchers have documented hundreds of deaths where kratom-derived chemicals were present in postmortem blood tests. But rarely is kratom deadly by itself. In a study of 551 kratom-related deaths in Florida, 93.5% involved other substances such as opioids like fentanyl.

I study pharmaceutical sciences, have taught for over 30 years about herbal supplements like kratom, and I’ve written about kratom’s effects and controversy.

One Name, Many Products

Kratom is a broad term used to describe products made from the leaves of a Southeast Asian tree known scientifically as Mitragyna speciosa. The Latin name derives from the shape of its leaves, which resemble a bishop’s miter, the ceremonial, pointed headdress worn by bishops and other church leaders.

Kratom is made from dried and powdered leaves that can be chewed or made into a tea. Used by rice field workers and farmers in Thailand to increase stamina and productivity, kratom initially alleviates fatigue with an effect like that of caffeine. In larger amounts, it imparts a sense of well-being similar to opioids.

In fact, mitragynine, which is found in small amounts in kratom, partially stimulates opioid receptors in the central nervous system. These are the same type of opioid receptors that trigger the effects of drugs such as morphine and oxycodone. They are also the same receptors that can slow or stop breathing when overstimulated.

In the body, the small amount of mitragynine in kratom powder is converted to 7-OH by liver enzymes, hence the opioid-like effects in the body. 7-OH can also be made in a lab and is used to increase the potency of certain kratom products, including the ones found in gas stations or liquor stores.

And therein lies the controversy over the risks and benefits of kratom.

‘No Currently Accepted Medical Use’

Because kratom is a plant-derived product, it has fallen into a murky enforcement area. It is sold as an herbal supplement, normally by the kilogram from online retailers overseas.

In 2016, I wrote a series of articles for Forbes as the Drug Enforcement Administration proposed to list kratom constituents on the most restrictive Schedule 1 of the Controlled Substances Act. This classification is reserved for drugs the DEA determines to possess “no currently accepted medical use and a high potential for abuse,” such as heroin and LSD.

But readers countered the DEA’s stance and sent me more than 200 messages that primarily documented their use of kratom as an alternative to opioids for pain.

Others described how kratom assisted them in recovery from addiction to alcohol or opioids themselves. Similar stories also flooded the official comments requested by the DEA, and the public pressure presumably led the agency to drop its plan to regulate kratom as a controlled substance.

But not all of the stories pointed to kratom’s benefits. Instead, some people pointed out a major risk: becoming addicted to kratom itself. I learned it is a double-edged sword – remedy to some, recreational risk to others. A national survey of kratom users was consistent with my nonscientific sampling, showing more than half were using the supplement to relieve pain, stress, anxiety or a combination of these.

Natural Leaf Powder vs Concentrated Extracts

After the DEA dropped its 2016 plan to ban the leaf powder, marketers in the U.S. began isolating mitragynine and concentrating it into small bottles that could be taken like those energy shots of caffeine often sold in gas stations and convenience stores.

This formula made it easier to ingest more kratom. Slowly, sellers learned they could make the more potent 7-OH from mitragynine and give their products an extra punch. And an extra dose of risk.

People who use kratom in the powder form describe taking 3 to 5 grams, the size of a generous tablespoon. They put the powder in capsules or made it into a tea several times a day to ward off pain, the craving for alcohol or the withdrawal symptoms from long-term prescription opioid use.

Since this form of kratom does not contain very much mitragynine – it is only about 1% of the powdered leaf – overdosing on the powder alone does not typically happen.

That, along with pushback from consumers, is why the Food and Drug Administration is proposing to restrict only the availability of 7-OH and not mitragynine or kratom powder. The new Colorado law limits the concentration of kratom ingredients in products and restricts their sales and marketing to consumers over 21.

Even David Bregger supports this distinction. “I’m not anti-kratom, I’m pro-regulation. What I’m after is getting nothing but leaf product,” he told WPRI in Rhode Island last year while demonstrating at a conference of the education and advocacy trade group the American Kratom Association.

Such lobbying with the trade group last year led the American Kratom Association to concur that 7-OH should be regulated as a Schedule 1 controlled substance. The association acknowledges that such regulation is reasonable and based in science.

Potential Use as Medicine

Despite the local and national debate over 7-OH, scientists are continuing to explore kratom compounds for their legitimate medical use.

A $3.5 million NIH grant is one of several that is increasing understanding of kratom as a source for new drugs.

Researchers have identified numerous other chemicals called alkaloids from kratom leaf specimens and commercial products. These researchers show that some types of kratom trees make unique chemicals, possibly opening the door to other painkillers.

Researchers have also found that compounds from kratom, such as 7-OH, bind to opioid receptors in unique ways. The compounds seem to have an effect more toward pain management and away from potentially deadly suppression of breathing. Of course, this is when the compounds are used alone and not together with other sedating drugs.

Rather than contributing to the opioid crisis, researchers suspect that isolated and safely purified drugs made from kratom could be potential treatments for opioid addiction. In fact, some kratom chemicals such as mitragynine have multiple actions and could potentially replace both medication-assisted therapy, like buprenorphine, in treating opioid addiction and drugs like clonidine for opioid withdrawal symptoms.

Rigorous scientific study has led to this more reasonable juncture in the understanding of kratom and its sensible regulation. Sadly, we cannot bring back Daniel Bregger. But researchers can advance the potential for new and beneficial drugs while legislators help prevent such tragedies from befalling other families.

How To Get More Pain Relief From Rx Opioids

By Drs. Forest Tennant, Martin Porcelli and Scott Guess

Due to a multitude of legal restrictions and biases, many persons living with pain who take opioid medication can’t get enough relief to function, be comfortable, and have quality of life.

Summarized below are some of the ways we have found to boost or enhance the pain-relieving effect of prescription opioids.

Take a Booster (Potentiator)

Opioids trigger the endorphin receptor to relieve pain. If you simultaneously take a medicine or supplement that triggers a different receptor or suppresses inflammation, pain relief is enhanced. This boosting effect is the reason opioids are combined with acetaminophen or aspirin in pain medications such as Vicodin or Percocet.

Here is a list of potential non-prescription boosters. You may have to experiment to find one or two that boost the potency of your opioid. You can swallow the booster with your oral opioid or take the booster within 15 minutes after taking the opioid.

• Taurine 1000 mg

• Glutamine 1000 mg

• Lion’s Mane mushrooms

• Quercetin

• Benadryl

• St. John’s wort

• White willow bark

• Cannabidiol (CBD)

• Kava

• Palmitoylethanolamide (PEA) 300 to 600 mg

Under the Tongue vs Swallowing

A medication dissolved under the tongue (sublingually) is always more potent than if you swallow it whole. That’s because digestion in the stomach and intestines may wipe out as much as 50% of an oral opioid’s pain relief capability.

Try dissolving an opioid tablet under your tongue. You may find it much more effective, as it will enter the bloodstream faster. We recommend starting with half your usual dose and increase it as needed, being careful not to exceed your usual dose. Discuss this practice with your medical practitioner.

Don’t Forget Aspirin

Aspirin has been disparaged to the point that people are afraid to take it. It is still one of the very best opioid boosters. Dissolve it under your tongue to avoid stomach upset or bleeding.

Receptor Health

The central nervous system has many receptors (“action points”) that relieve pain. They need to stay healthy and active to provide maximal pain relief. A good nutrition program that consists of daily protein, vitamin D, and magnesium helps keep nerve receptors healthy and maximizes opioid pain relief.

Bedtime Preparation

Some medicinals taken at bedtime have the effect of making the next day’s opioids more effective. Here are some suggestions:

• Metformin 500 mg + L-Theanine 200 mg

• Tryptophan 500 to 1000 mg

• Amitriptyline

• Pentoxifylline

Cannabis

Some persons find that cannabis provides significant pain relief, while others experience little or no relief.

Do not take cannabis products within four hours before or after an opioid dosage to avoid over-sedation, loss of coordination, and mental deficiency.

Kratom

Kratom is the only non-prescription herbal supplement that has opioid-like effects. It comes in a variety of forms, usually natural leaf powder that is sold in capsules, edibles or drinks.

Kratom can be simultaneously taken with opioids, but be wary of synthetic or concentrated kratom as its potency may be unknown or too high.

All persons who take opioids for pain relief should find a kratom form and dosage that relieves pain. Given today’s adverse attitudes and restrictions on opioids, a person relying on prescription opioids alone must face the fact that their medical practitioners may end or reduce their opioid therapy at any time. When this happens, you may have to rely on kratom.

Prescription Boosters

Many physicians prescribe non-opioid medications for pain relief, such as gabapentin (Neurontin), clonidine, tizanidine, baclofen, and pregabalin (Lyrica). These can also be used to boost the potency of opioids. Take these medications within four hours before or after your opioid dose.

Experimental Brain Implant Gives Long-Term Relief from Chronic Pain

By Crystal Lindell

An experimental brain implant that detects when someone is in pain and responds by stimulating the brain with tiny electrodes provided long-term relief from chronic pain, according to a small new study led by researchers at the University of California, San Francisco (UCSF) 

The preprint study, which has not yet been peer-reviewed, involved six patients with severe chronic nerve pain that did not respond to conventional treatment. The patients were hospitalized for 10 days so that researchers could put temporary electrodes in their brains to target areas involved in pain processing with deep brain stimulation (DBS). 

Of the six patients, five had clinically meaningful pain relief. Those five patients then had the experimental DBS implants permanently placed in their brains. Over the next six months, brain activity and pain signals were recorded to create a personalized “map” of each brain 

The system then used each patient’s unique brain signals (pain “biomarkers”) to decide in real time when to turn the low frequency stimulation on or off. Referred to as “closed-loop DBS,” the implants did not run continuously, but automatically adjusted when pain was felt and turned off when patients were asleep. 

Patients were also given sham placebo stimulation in brain areas outside the ideal location to serve as a comparison..  

The closed-loop DBS system worked better than the placebo treatment. Researchers say they identified several brain areas that gave quick pain relief when stimulated, and that they could accurately predict people’s pain levels just from their brain activity. 

On average, the DBS implants reduced pain intensity by 50 percent, while the sham treatment increased pain levels. Patients also were able to walk further after real stimulation – their step counts rose by 18 percent – compared to just one percent with sham treatment. For some patients, the benefits lasted over three years. 

“In five participants, we observed acute, rapid pain relief which translated into long-term efficacy after permanent closed-loop DBS for up to 3.5 years,” researchers reported. One patient who suffered from chronic pain after a stroke experienced “profound and durable pain relief.” 

The implant surgeries, however, were not trouble free. Two participants experienced serious adverse events related to surgery, but continued in the trial and experienced no serious adverse events related to stimulation. 

“Our study is limited by a small sample size, constraining the generalizability of these findings to other chronic pain syndromes. Although we observed initial evidence of sustained benefits up to 3.5 years, additional follow up is required to monitor for late-emerging tolerance,” researchers concluded.

Previous attempts to use deep pain stimulation for pain relief have been “inconsistent with poor long-term results.”  Those prior attempts, however, used a one size-fits-all-approach and did not target specific brain regions for each patient, as the UCSF study did..

DBS is being used to treat movement disorders associated with Parkinson’s disease, tremors, and other neurological conditions. It is also used to manage some psychiatric conditions. DBS is considered a treatment of last resort for patients that don’t respond well to medications or have severe side effects from them.

FDA Approves First Implant That Zaps Rheumatoid Arthritis

By Madora Pennington

A nerve stimulation implant recently approved by the FDA reduces symptoms of rheumatoid arthritis by stimulating the vagus nerve with mild electronic pulses. It’s the first FDA-approved neuromodulation device for adults with moderate-to-severe rheumatoid arthritis (RA).

The vagus nerve stimulator (VNS), created by SetPoint Medical of Valencia, California, is the size of a coffee bean. It is implanted in the left side of the neck under anesthesia during an outpatient procedure.

The device delivers electronic pulses into the vagus nerve for just one minute each day to calm the immune system and have an anti-inflammatory effect. RA causes the immune system to attack the lining of joints, damaging cartilage and eroding bone.

“The approval of the SetPoint System, the first-in-class neuroimmune modulation platform, represents a transformative milestone in the management of autoimmune diseases,” Murthy Simhambhatla, PhD, CEO of SetPoint Medical, said in a press release. “We plan to introduce the SetPoint System in targeted U.S. cities this year, followed by expansion across the country starting in early 2026.”

In auto-immune diseases like RA, the function of the vagus nerve becomes impaired. The nerve starts in the brainstem and runs through the neck, chest and abdomen, where it branches out into many organs.

The vagus nerve helps regulate the nervous system, including heart rate, blood pressure, respiration and digestion. When the nerve malfunctions, it causes inflammation and disrupts the immune system.

In a clinical trial of 242 patients, just over half (51.5%) had at least a 20% improvement in RA symptoms after 24 weeks with the SetPoint implant. Most patients tolerated the device well, but two experienced side effects of vocal cord weakness and hoarseness.

SETPOINT MEDICAL IMAGE

The SetPoint System is intended for RA patients who have not benefited from medications designed to calm the immune system, known as Disease-Modifying Antirheumatic Drugs (DMARDS) or the much stronger biologics that target specific immune cells. Doctors can monitor the device with an iPad application and patients can recharge it themselves with a wireless charger.

Vagus nerve stimulation is not new. In 1997, the FDA approved VNS for epilepsy. The implanted device is installed in the chest like a pacemaker to reduce seizures or even stop ones in progress.  

VNS can also treat chronic pain, by helping the brain "turn down" pain signals and reduce pain indirectly through its anti-inflammatory effects.  

Other types of pain for which VNS has demonstrated effectiveness are chronic migraine, chronic primary headache, cluster headache, fibromyalgia, chronic pancreatitis, esophageal pain, irritable bowel syndrome, neuropathic pain, musculoskeletal pain, osteoarthritis, and chronic low back pain.

SetPoint is investigating whether its technology can also treat multiple sclerosis, Crohn's disease and other autoimmune conditions.

When Headlines Lie: Misleading News About Opioids and Chronic Pain

By Neen Monty

The headline in Physician’s Weekly screams alarm:

“Rising Use of Potent Opioids in Chronic Pain Management”

And then the sub heading:

“Long-term opioid use for chronic pain doubled, with potent opioids rising, underscoring the need for stronger guideline adoption”

Terrifying, right? We must do something!

But now, read the article. It’s based on a study recently published in the European Journal of Pain on the prevalence of long-term opioid therapy (LTOT) when treating patients with chronic non-cancer pain.

The Dutch study looked at opioid use over a ten-year period, from 2013 to 2022, using a large dataset drawn from primary care records in the Rotterdam region. This database covered more than half a million patients and included data from over 240 general practitioners.

The researchers focused on adults aged 18 and over who had been prescribed opioids continuously for at least three months. They tracked how common LTOT was over time, and also explored which diagnoses, co-existing conditions, and other medications were associated with it. They reported their findings using basic descriptive stats and calculated LTOT prevalence per 100 patient-years to show trends over the decade.

And what did they find?

“The prevalence of LTOT increased twofold from 0.54% (95% CI: 0.51–0.58) per 100 patient years in 2013 to 1.04% (95% CI: 1.00–1.07) in 2022. The proportion of LTOT episodes solely involving potent opioids slightly increased between 2013 and 2022”

In plain English, the prevalence of long-term opioid use by patients at the end of the study was just over 1%.

Yes, that’s right: 1%.

And the prevalence increased by just half a percentage point over a decade.

Hardly a crisis. Hardly anything to scream about.

But we can’t have that! We need a clickbait headline to demonize opioids and stop their prescribing! So, instead of reporting accurately on the very small increase in opioid prescribing, they focus on the “twofold” increase. Trying to manufacture a crisis where there is none.

It’s true, the prevalence of LTOT did double, from half a percent to one percent. And that’s what the headline highlighted, to try and make it sound like there is an opioid crisis in Europe. There is not.

This tactic is often used in presenting medical research – using relative percentages rather than the actual numbers. That is because relative percentages -- “Opioid Use Doubled!” -- sounds worse than “Opioid Use Increased by Half a Percent.”

It’s a trick that researchers and the media use all the time.

Why do this? It’s dishonest. It’s deceptive. And it destroys our trust in science. They are trying to manufacture a crisis when there is none.

Why not research and report an actual crisis? Instead of making one up?

The Physician’s Weekly headline exemplifies the worst of scientific spin: inflating tiny fractional changes and omitting context. It potentially harms patients by reinforcing the myth that opioids don’t work long term and should be withheld. That myth persists because of misleading reporting like this.

Finally! An Honest Headline

It was nice to see some accurate reporting in Scimex, an Australian online news portal that tries to help journalists cover science. Instead of the usual deceptive, sensationalist headlines, this one tells the truth:

“Pain Reprocessing Therapy (PRT) could help those with mild chronic back pain”

This was so refreshing to see! Because it’s so very, very rare.

Most reporting on PRT glosses over a critical point: It has only been studied in people with mild, non-specific back pain. An average of 4 on the zero-to-10 pain scale.

That nuance is often lost in the hype about alternative treatments like PRT, cognitive behavioral therapy, mindfulness and TENS.

You do not treat 8/10 back pain the same way you treat 4/10 back pain.

What happens when people are misled about PRT? It gets recommended to people with severe, pathological pain — often with clearly identifiable causes — and everyone acts surprised when it doesn’t work.

Let’s be clear:

• PRT is not for severe back pain

• PRT is not for pain caused by pathology

• PRT is not a cure-all

But you wouldn’t know that from most headlines about PRT, such as “New therapy aims to cure back pain without drugs, surgery” and “A New Way to Treat Back Pain.”

Then you read the small print: All the participants in PRT studies had non-specific back pain from an unknown cause. And they had mild pain.

The researchers are often complicit, cherry-picking and hyping their own data. Why? Because they need funding. Because they’re writing a book. Because professors have to "publish or perish" to keep their jobs. Because it’s easier to mislead the public than to admit a therapy has limits. And you don’t get to be a guru if your therapy only works for a minority of patients with mild pain.

This kind of spin harms people with severe chronic secondary pain. It feeds the narrative that if you're still in pain, then it’s your fault. You didn’t try hard enough. You’re catastrophizing. You need to retrain your brain.

It feeds the stigma that all chronic pain is mild and easily curable. And that anyone who says their pain is severe has psychological problems.

No. Maybe their pain is caused by pathology, like tissue damage or herniated discs. Maybe their pain is nociceptive or neuropathic.

This is why chronic pain patients must be included on every research team. Someone with real-world, high-impact chronic pain would never let this kind of misrepresentation slide. And the rest of the team wouldn’t be able to claim ignorance.

We need more honesty and integrity in research and the media. We need headlines that reflect the actual findings. We need conclusions that match the data, not some predetermined narrative. Right now, most media coverage doesn’t even try.

Read the study, then read the headline. They rarely match. That’s how we ended up with a generation of healthcare providers who think opioids are bad, all chronic pain is primary pain, and that PRT is some miracle therapy.

It’s not. PRT may be helpful to people who are depressed or have anxiety, but should not be a first-line treatment for everyone. It’s only been tested in people with mild back pain for which there is no known physical cause. It has not been shown to work for people with severe pain or structural pathology.

But the researchers usually gloss over that. And the headlines and conclusions rarely reflect those facts or spell out who PRT is for and who it is not for.

Because here’s the truth: Pain Reprocessing Therapy is not a treatment for chronic pain. It’s a treatment for anxiety and depression.

That’s the real headline.

‘A Lot of Uncertainty’ if Ketamine Works for Chronic Pain

By Pat Anson

Hundreds of ketamine clinics have opened across the United States in recent years, offering infusions of the anesthetic for a variety of medical conditions – from anxiety and depression to PTSD and chronic pain. Ketamine is only FDA-approved for depression and anesthesia, so its use in treating pain is considered “off-label.”

That off-label use is not supported by scientific evidence, a new Cochrane review has found. Australian researchers analyzed 67 clinical trials involving over 2,300 adults who used ketamine or four similar drugs that block brain receptors and found little evidence that they work as pain relievers.

“We want to be clear – we're not saying ketamine is ineffective, but there’s a lot of uncertainty,” said lead author Michael Ferraro, a doctoral candidate at the University of New South Wales (UNSW). “The data could point to a benefit or no effect at all. Right now, we just don’t know.”

Ferraro and his colleagues looked at the therapeutic effects of ketamine, memantine, dextromethorphan, amantadine and magnesium on various chronic pain conditions and found no evidence that they benefit any condition at any dose. Side effects such as delusion, delirium and paranoia were a major concern, particularly with intravenous use.

"This group of drugs, and ketamine in particular, are in relatively common use for chronic pain around the world. Yet we have no convincing evidence that they are delivering meaningful benefits for people with pain, even in the short term,” said co-author Neil O'Connell, a Professor of Evidence-Based Healthcare at Brunel University of London.

“That seems a good reason to be cautious in the clinic and clearly indicates an urgent need to undertake high quality trials.”

The reviewers also found no studies that support two supposed benefits of ketamine: that it reduces depression and the use of opioids. Ketamine is often used as a treatment for depression or as an alternative to opioids for pain relief.

“We've seen the harm that can come from taking medicines developed for acute pain and applying them to chronic pain, opioids are a prime example. Now we're seeing a similar pattern with ketamine,” said co-author James McAuley, PhD, a Psychology Professor at UNSW and senior researcher at Neuroscience Research Australia.

“As opioid prescribing is slowly reduced, there’s a growing demand for alternatives, but we need to be careful not to rush into widespread use without strong evidence.”

A ‘Lifeline’ for Pain Patients

But patients who have received ketamine infusions found them useful in relieving pain from Complex Regional Pain Syndrome (CRPS) and other difficult-to-treat conditions.

“I implore the medical community not to dismiss ketamine as a treatment option based solely on this one review, when tens of thousands of us are finding relief,” says Barby Ingle, founder and past president of the International Pain Foundation. “For many of us, ketamine is not just an option — it’s a lifeline.

“Chronic pain is a complex, individualized condition, and ruling out therapies that benefit even a subset of patients perpetuates a one-size-fits-all approach that has long plagued healthcare. Such dismissals increase costs to society by limiting access to effective treatments, leaving patients to suffer unnecessarily. I have lost too many friends to suicide with these painful rare diseases.”

In 2009, Ingle had her CRPS, also known as Reflex Sympathetic Dystrophy (RSD) or algoneurodystrphy, treated for the first time with ketamine by the late Dr. Robert Schwartzman, a neurologist who pioneered the use of ketamine infusions as a chronic pain treatment. She went into the hospital in a wheelchair, but was able to walk out a week later after a series of ketamine infusions by Schwartzman. She continues to get infusions regularly.

“My experience with IV-ketamine has allowed me to manage my pain without the fear of addiction or life-threatening side effects, further emphasizing its value as a treatment option long-term,” Ingle told PNN.  

“Ketamine can offer significant advantages over opioids, as it is non-addictive and does not suppress breathing, making it a safer option for long-term pain management. These benefits are particularly crucial for patients with chronic pain, who often face the risks of opioid dependence and respiratory complications. For other patients due to their genetics, lifestyle, and environment, opioids may be the best option. I am saying don’t take any option off the table.”

Ingle says rigorous, high-quality clinical studies are needed to document the benefits of ketamine therapy. Of the 67 studies that were reviewed by researchers, many were small or short-term, which limited their ability to draw conclusions.

Some U.S. medical organizations support the use of ketamine under certain circumstances. The American Society of Anesthesiologists, American Society of Regional Anesthesia and Pain Medicine, and the American Academy of Pain Medicine have guidelines that support ketamine infusions for CRPS, chronic neuropathic pain and short-term acute pain.

From Arthritis to Pain Relief: 5 Benefits of Ginger

By Dipa Kamdar

From warming winter teas to zesty stir-fries, ginger (Zingiber officinale) has long been a kitchen staple. But beyond its culinary charm, this spicy root has a rich history in traditional medicine – and modern science is catching up. Studies now show that ginger may offer a wide range of health benefits, from easing nausea and relieving colds to reducing inflammation and supporting heart health.

Here’s what you need to know:

1. Nausea Relief

Multiple clinical trials have shown consistent evidence that ginger can reduce nausea and vomiting, particularly when compared to a placebo. The NHS even recommends ginger-containing foods or teas for easing nausea.

Ginger seems especially effective for nausea during pregnancy. In small doses, it’s considered a safe and effective option for people who don’t respond well to standard anti-nausea treatments.

There’s also promising evidence that ginger can help with chemotherapy-induced nausea, though results are mixed when it comes to motion sickness and post-surgery nausea.

Researchers believe ginger’s anti-nausea effects may work by blocking serotonin receptors and acting on both the gut and brain. It may also help by reducing gas and bloating in the digestive tract.

2. Anti-Inflammatory Benefits

Ginger is rich in bioactive compounds, such as gingerol and shogaol, which have strong antioxidant and anti-inflammatory properties.

Recent research suggests ginger supplements may help regulate inflammation, especially in autoimmune conditions. One study found that ginger reduced the activity of neutrophils — white blood cells that often become overactive in diseases like lupus, rheumatoid arthritis and antiphospholipid syndrome.

Neutrophils produce extracellular traps (NETs), which are web-like structures used to trap and kill pathogens. But when NETs form excessively, they can fuel autoimmune diseases. In the study, taking ginger daily for one week significantly reduced NET formation.

While this study used ginger supplements, it’s unclear whether fresh ginger or tea has the same effect. Still, the findings suggest ginger may be a helpful, natural option for people with certain autoimmune conditions – though more research is needed.

Ginger also has antimicrobial properties, meaning it can help combat bacteria, viruses and other harmful microbes. Combined with its anti-inflammatory effects, this makes ginger a popular remedy for easing cold and flu symptoms like sore throats.

3. Pain Management

When it comes to pain, the research on ginger is encouraging – though not conclusive. Some studies show that ginger extract can reduce knee pain and stiffness in people with osteoarthritis, especially during the early stages of treatment. However, results vary, and not everyone experiences the same level of relief.

For muscle pain, one study found that taking two grams of ginger daily for 11 days reduced soreness after exercise.

Ginger may also ease menstrual pain. In fact, some studies suggest its effectiveness rivals that of non-steroidal anti-inflammatory drugs like ibuprofen.

Researchers believe ginger works by activating pathways in the nervous system that dampen pain signals. It may also inhibit inflammatory chemicals like prostaglandins and leukotrienes.

4. Heart Health and Diabetes Support

High blood pressure, high blood sugar and elevated “bad” cholesterol (low-density lipoprotein or LDL cholesterol) are all risk factors for heart disease. Ginger may help with all three.

A 2022 review of 26 clinical trials found that ginger supplementation can significantly improve cholesterol levels — lowering triglycerides, total cholesterol and LDL cholesterol, while raising HDL (“good”) cholesterol. It may also lower blood pressure.

For people with type 2 diabetes, ginger could offer additional benefits. A review of ten studies found that taking one to three grams of ginger daily for four to 12 weeks helped improve both cholesterol levels and blood sugar control.

These benefits appear to come from multiple mechanisms, including improved insulin sensitivity, enhanced glucose uptake in cells, and reduced oxidative stress. Ginger’s anti-inflammatory actions may also contribute to its heart-protective effects.

Some early research suggests that ginger may also offer benefits for sexual health, though evidence in humans is still limited. Animal studies have found that ginger can boost testosterone levels, improve blood flow, and enhance sexual behaviour. In traditional medicine systems, it has long been used as an aphrodisiac. While there’s not yet strong clinical evidence to confirm a direct impact on libido, ginger’s anti-inflammatory, circulatory and hormonal effects could play a supportive role, particularly for people managing conditions like diabetes or oxidative stress.

5. Brain Health

Emerging evidence suggests ginger may also offer neuroprotective and anti-cancer benefits. Lab-based studies show that ginger compounds can help protect brain cells from oxidative damage – a key factor in neurodegenerative diseases like Alzheimer’s.

Other in-vitro research has found that ginger can slow the growth of some cancer cells. However, these findings are still in early stages and more research is needed to confirm their relevance in humans.

Ginger is generally safe when consumed in food or tea. But like any supplement, it should be used in moderation.

Doses above four grams a day may cause side effects such as heartburn, bloating, diarrhoea or mouth irritation. These are usually mild and temporary.

Certain groups should use caution with high doses. Ginger may increase bleeding risk in people on blood thinners (like warfarin, aspirin or clopidogrel), and it can enhance the effects of diabetes or blood pressure medications, potentially leading to low blood sugar or blood pressure. Pregnant women should also consult a doctor before using high doses.

So ginger isn’t just a fragrant kitchen spice – it’s a natural remedy with growing scientific support. For most people, enjoying ginger in food or tea is a safe and effective way to tap into its therapeutic potential. If you’re considering taking supplements, it’s always best to speak with your doctor or pharmacist first, especially if you’re managing a medical condition or taking medication.

Can AI Videos Replace In-Person Physical Therapy?

By Crystal Lindell

A UK-based technology company claims their Artificial Intelligence (AI) videos are good enough to replace in-person physical therapy for some back pain patients. 

Like the United States, the waiting time in the UK to see a medical specialist can be daunting. According to the UK’s National Health Service (NHS), the average wait time after a referral for simple back or spine pain is more than 18 weeks. Nearly 350,000 people in England were on waiting lists for treatment for musculoskeletal problems last year. 

But in a pilot study of over 2,500 NHS patients who used a physiotherapy (physical therapy) app operated by Flok Health, the waiting times were cut in half. 98% of referred patients continued watching the AI powered videos, while only 2% required or requested a transfer to traditional to face-to-face care with a therapist.

The app works by showing patients pre-recorded videos of actual human instructors, but then tailors the video clip order based on how AI interprets responses from the patient. 

“Each appointment is like a 30 minute video call, except our side of the call is created by our AI engine in real-time, just for you,” Flok Health explains on its website. “You can answer questions and your digital physio will respond to you live, in a continuously generated personal video stream.”

Patients are also prescribed a set of exercises for the coming week before the next appointment. Flok Health says the exercises are specifically selected based on “a detailed analysis of symptoms and movement patterns.” The app also guides patients through practicing their exercises between appointments, and helps them see their progress and stay on track.

Patients also have access to human physiotherapists and doctors. The company said they monitor patient recovery remotely and can arrange to speak to a patient if they have questions. 

The BBC's Scott Nover tried the app back in March and wrote about his experience with an AI generated physical therapist named “Kirsty.” He found her recommendations lacking, with his main complaint being that Kirsty wasn’t able to correct his form in real time like a live therapist would.

“The big difference here is that Kirsty can't see me. Her pre-recorded videos don't watch my movements and stretches. They rely on me following her instructions correctly and reporting if something is amiss,” Nover wrote.

“My back felt better after my sessions with Flok, but the app likely isn't for me. I'm clumsy and uncoordinated and need someone watching my form at all times – if not, I'm likely to hurt myself further.”

However, I could see a near-future scenario where AI is able to analyze patient form in real-time with technology that’s similar to that used in gaming counsels like XBox Kinect. 

Nover also pointed to a 2024 study for a similar AI-powered back pain treatment called selfBACK that found patients were unlikely to use it. Nearly one-third of patients never accessed the app, and another third rarely used it. 

It’s definitely easier to blow off an app than it is to blow-off an in-person physical therapy appointment with an actual human being, so those results make sense. 

As a patient, I’ve had both in-person physical therapy referrals given to me sometimes, and links to relevant videos with accompanying handouts provided to me at other times. 

To be frank, this Flok Health app sounds a lot like that latter. And I will confess that I was a lot less likely to follow a physical therapy treatment plan when it didn’t involve an actual physical therapist.

At the same time, at least in the United States, physical therapy can be very expensive, especially when there’s a high co-pay for each session. So having less expensive treatment options is a good thing. Although it’s unclear when Flock might be widely available to U.S. patients.

I’m skeptical that AI will be fully replacing physical therapists any time soon, but it sounds like tech companies are hoping they can make a massive dent in their client base and waiting times..

Poor Nutrition Linked to Higher Risk of Chronic Pain

By Crystal Lindell

Vitamin and mineral deficiencies could play a key role in chronic pain, according to new research that found low levels of Vitamin D, B12, folate and magnesium were common in people with severe chronic pain. 

The study, led by researchers at the University of Arizona Health Sciences, analyzed health data on over 220,000 people in the National Institutes of Health’s “All of Us” Research Database. The study is the first to look at micronutrient levels of people with and without chronic pain on a large scale.

“I treat chronic pain patients, and oftentimes we don’t come up with a diagnosis. But just because there isn’t a surgery that will help you doesn’t mean you’re not in pain. It just means that our understanding of pain is limited to date,” said senior author Julie Pilitsis, MD, head of the Department of Neurosurgery at U of A College of Medicine–Tucson.

“This study is a novel way to approach chronic pain treatment, where you are looking at the patient holistically to see what could be going on systemically that is easily modifiable – changes in diet as opposed to medications or other things.”

Pilitsis and her colleagues focused on five micronutrients commonly associated with chronic pain: vitamins D, B12, and C, folate and magnesium. Nutritional data was analyzed for people without pain, those with mild-to-moderate chronic pain, and people with severe chronic pain.

They found that people with severe chronic pain were more likely to have deficiencies in vitamin D, vitamin B12, folate and magnesium. The findings, however, varied depending on gender, race and ethnicity.

“The finding that surprised us the most was that Asian females had higher vitamin B12 levels than expected,” said co-author Deborah Morris, PhD, a research laboratory manager in the Department of Neurosurgery. “Asian females with severe chronic pain had the highest vitamin B12 levels overall. We were expecting it to be lower.”

The results also varied for vitamin C, where males with mild-to-moderate or severe chronic pain were more likely to have low or borderline low levels of vitamin C, compared to males without pain. 

Researchers caution that they didn’t prove a cause-and-effect relationship between nutrition and pain, but they believe their findings could lead to personalized diets and nutritional supplements for people with chronic pain. 

The Western Diet, which is common in the United States, is deficient in fruits and vegetables and contains high amounts of meat, refined grains, and desserts. This could contribute to nutritional imbalances and deficiencies in micronutrients. 

Frustratingly, like so much medical research regarding chronic pain these days, it seems one of the primary goals of the researchers is to reduce opioid use. 

“Our goal is to improve the quality of life for people with chronic pain and reduce opioid usage, and these findings have the potential to do that as part of a holistic approach to pain management,” said Morris. 

Note how she doesn’t say she wants to help patients reduce ibuprofen or gabapentin use, despite the fact that both can cause serious side effects. 

I’m glad to see more progress when it comes to understanding the causes of chronic pain –  especially since I suffer from it – but constantly framing every advancement as a way to “reduce opioid use” is disappointing. Opioid prescriptions have already been greatly reduced to levels not seen in over 20 years.

While chronic pain patients should obviously be making sure their vitamin and mineral levels are within the normal range, my fear is that doctors will over-correct – and start pushing vitamins and supplements as alternatives to pain medication. 

I myself suffered from extremely low vitamin D levels, and I do find that keeping it in the normal range helps reduce my pain levels. Holistic treatments can be a good thing, but only if they are truly holistic – encompassing both non-traditional and traditional approaches. 

Why Ice Cream May Be Bad for Your Gut Health

By David Hilzenrath, KFF Health News

It’s a marvel of food technology: ice cream that resists melting. In a video explaining the science behind it, a seller of food chemicals shows scoops of ice cream holding their shape under hot lights. The super ingredient? Polysorbate 80.

Polysorbate 80 is an emulsifier, a chemical used to control the consistency of thousands of supermarket products. Other widely used emulsifiers or stabilizers include carboxymethyl cellulose, carrageenan, and maltodextrin.

Recently, such ingredients have been showing up in scientific studies for another reason: Researchers say they may cause a variety of health problems.

Studies have found that emulsifiers can alter the mix of bacteria in the gut, known as the microbiome or microbiota; damage the lining of the gastrointestinal tract; and trigger inflammation, potentially contributing to problems elsewhere in the body.

Emulsifiers and stabilizers are among the most common ingredients in ultra-processed foods, a prime target of the “Make America Healthy Again” campaign by Health and Human Services Secretary Robert F. Kennedy Jr.

They are on the department’s radar: Their potentially harmful effects were flagged in a document HHS recently produced to support Kennedy’s drive to eliminate petroleum-based food dyes. But they illustrate the complexity of the war on food additives.

They show how, when it comes to food science, regulators are chronically playing catch-up. In the meantime, for many ingredients, regulators and consumers alike are left in a gray zone between suspicion and proof of harm in humans.

Emulsifiers’ assault on the microbiome could help explain inflammatory bowel diseases such as Crohn’s disease and ulcerative colitis, metabolic disorders, and even cancer, the studies suggest.

“There is a lot of data showing that those compounds are really detrimental for the microbiota and that we should stop using them,” said Benoit Chassaing, a research director at the French National Institute of Health and Medical Research and a co-author of several related studies.

Yet much larger and more ambitious clinical trials in humans are needed, Chassaing added.

For Lewis Rands, who has suffered from gastrointestinal illness, the research fits his own experience as a consumer. Changing his diet to avoid emulsifiers has made a shocking difference, easing symptoms that were debilitating, Rands said.

“Clinically, many patients have reported an improvement in symptoms with such changes,” said Ashwin Ananthakrishnan, a gastroenterologist and researcher at Massachusetts General Hospital.

The scientific findings come with caveats. For instance, much of the research has been done in mice, or by mimicking the human gut in a tube. There are many unknowns. Not all emulsifiers have bad effects, or the same effects, and some people are thought to be much more vulnerable than others.

Even some researchers who have co-authored papers say that the substances have not been proven harmful to humans and that it’s too soon to say regulators should ban them.

Still, the research poses a challenge for the FDA. When emulsifiers began spreading through the food supply, the agency wasn’t focusing on the gut microbiome, a relatively recent scientific frontier, researchers said.

Martin Makary, appointed by President Donald Trump to head the FDA, mentioned the microbiome at his Senate confirmation hearing in March. Though he didn’t cite emulsifiers specifically or identify chemicals by name, he said substances that affect the microbiome deserve the FDA’s attention.

“There’s a body of research now that suggests concern with some of these ingredients,” Makary said. “We have to look at those ingredients, and you have my commitment to do so if confirmed as FDA commissioner.

“These chemicals are creating an inflammatory response in the gastrointestinal tract, and with an altered microbiome lining that GI tract, kids feel sick.”

The FDA and the Department of Health and Human Services did not respond to questions about Makary’s testimony.

However, when journalist Emily Kopp asked HHS for the science behind its recent announcement that it is phasing out petroleum-based food dyes, the agency provided a compilation of information on potentially harmful compounds commonly found in ultraprocessed foods. The document, which appeared to be a draft, included a section on emulsifiers, such as xanthan gum and carrageenan. It noted that the section needed more work.

HHS subsequently provided the document to KFF Health News.

As far back as 2020, an international organization for the study of inflammatory bowel diseases advised that, for people with those conditions, it “may be prudent to limit intake” of maltodextrin, carrageenan, carboxymethyl cellulose, and polysorbate 80.

Emulsifiers are developed from a variety of sources, including plants and bacteria. Some ingredients that might affect the microbiome show up in foods because they were deemed “generally recognized as safe,” or GRAS.

“New information may at any time require reconsideration of the GRAS status of a food ingredient,” the Code of Federal Regulations says.

Ben & Jerry’s vs Häagen-Dazs

Rands, a genetic scientist, took matters into his own hands to battle severe inflammatory bowel disease. The illness caused bloating, stomach pain, cramps, frequent bowel movements, and bleeding, he said.

It left him in a constant state of anxiety and stress, he added, wondering where the nearest bathroom was and whether he’d reach it in time. Even taking a walk around the block with his wife and baby near their home in Australia was problematic.

Then, on the advice of a dietitian, Rands began avoiding foods with emulsifiers: chemicals such as carboxymethyl cellulose, carrageenan, guar gum, xanthan gum, and maltodextrin — plus other additives.

For instance, instead of eating Ben & Jerry’s ice cream, he switched to Häagen-Dazs ice cream that is free of the substances at issue. The relief was dramatic.

“It’s a huge difference,” Rands said. “To me, it’s made more of a difference than any drug.”

He has been able to scale back or stop taking several drugs, which is an added relief — not least because some can have harmful side effects, and, he said, one was taking its toll.

Rands said he used a scientific approach, isolating variables in his diet and logging the results. Avoiding artificial sweeteners helps, he said, but most of the benefit relates to avoiding the emulsifiers.

Ben & Jerry’s did not respond to a request for comment.

‘Science That Hasn’t Been Done Yet’

The Consumer Brands Association, which represents makers of processed foods, stands behind use of the chemicals.

“Food safety and protecting the integrity of the food supply is priority number one for the makers of America’s food and beverage products,” Sarah Gallo, the group’s senior vice president of product policy, said in a statement. “Emulsifiers and thickening agents play an important role in improving food texture and consistency, and have been studied by the FDA through a rigorous scientific and risk-based process.”

Asked for specifics on how the FDA had analyzed potential effects on the microbiome, the group did not respond.

Chassaing said the chemicals were “never considered for the potential effect on the microbiota.”

Robert Califf, who led the FDA under Presidents Barack Obama and Joe Biden, said in an interview that scientists are just beginning to understand the microbiome. He compared it to where the field of genomics was 20 years ago, only much more complicated — “multiplied by a thousand dimensions.”

He said the substances “fell within the standards” when they were greenlighted. “But hopefully most people agree that the standards need to be upgraded,” he added.

“This is different than traditional food safety thinking about, ‘Does it cause an immediate problem?’” Califf said. “We’re talking about long-term health outcomes here.”

And has the FDA evaluated those?

“How could it? There was no way to do it,” Califf said. The answers will vary depending on the emulsifier, and “proving whether it’s bad or good is going to require rigorous science that hasn’t been done yet.”

More recent scientific capabilities expand the possibilities, he said.

‘A Lot of Confusion in the Field’

For a consumer, trying to steer clear of emulsifiers can be difficult. Without realizing it, people can consume a variety of emulsifiers from a variety of foods — and the same chemicals from multiple sources.

Polysorbate 80 was listed as an ingredient on the labels of 2,311 products as of May 12, according to an online database posted by the Environmental Working Group using information from NielsenIQ. Carrageenan was listed on 8,100 product labels; maltodextrin, 12,769; and xanthan gum, 17,153.

Some emulsifiers have multiple names, making them harder to recognize. Some names can apply to more than one emulsifier. And some chemical names that appear on product labels don’t appear in the FDA’s “Substances Added to Food” inventory.

Carboxymethyl cellulose — not to be confused with methyl cellulose — is also known as carboxymethylcellulose  and cellulose gum. Maltodextrin can be derived from substances such as cornstarch, rice starch, and wheat starch — but the FDA doesn’t consider it synonymous with the term “modified food starch.”

The naming practices can frustrate efforts to track the chemicals in food, to measure how much of the stuff people are taking in, and even to figure out precisely which chemicals a scientific study evaluated, researchers said.

“There’s a lot of confusion in the field,” said Christine McDonald, a researcher at the Cleveland Clinic who has studied maltodextrin. She called for more consistent naming of additives in the United States.

The very term “emulsifier” is problematic. By strict definition, emulsifiers create an emulsion — a stable blend of liquids that would not otherwise mix, such as oil and water. However, the term is used broadly, encompassing chemicals such as maltodextrin that thicken, stabilize, or alter texture.

Gummed Up

Emulsifiers can be found in foods marketed as natural or healthy as well as ones that look artificial. Some products contain multiple emulsifiers.

Products sold at Whole Foods, for instance, list a variety of emulsifiers on their labels. 365 brand Organic Vegan Ranch Dressing & Dip contained organic tapioca maltodextrin and xanthan gum.

Pacific Seafood Starfish brand Cornmeal Crusted Fishsticks — marked as wild-caught and MSC-certified (sustainably sourced) — contain guar gum. Flour tortillas by 365 included monoglycerides of fatty acids and “stabilizer (guar gum, xanthan gum, carrageenan).”

At a Safeway supermarket, Healthy Choice Grilled Chicken Pesto With Vegetables listed modified potato starch, modified corn starch, carrageenan, xanthan gum, and guar gum.

The label on Newman’s Own Caesar salad dressing said the product contained no artificial preservatives or flavors, no colors from an artificial source, and was gluten-free. The ingredient label listed, “as a thickener,” xanthan gum.

In response to questions for this article, Whole Foods Market said it prohibits more than 300 ingredients commonly found in food.

“Our experts evaluate ingredients for acceptability in all food products we sell based on the best available scientific research,” the company said in a statement provided by spokesperson Rachel Malish.

Safeway’s parent company, Albertsons Companies, did not respond to inquiries. Nor did Pacific Seafood, Newman’s Own, or Conagra Brands, which makes Healthy Choice.

A Growing Body of Research

Research on emulsifiers has been building in recent years.

For example, a study published in January by the Journal of Crohn’s and Colitis concluded that a diet low in emulsifiers is an effective treatment for mild or moderate Crohn’s disease. The eight-week clinical trial, which tracked 154 patients in the United Kingdom, focused on carrageenan, carboxymethyl cellulose, and polysorbate 80.

A study published in February 2024 in the journal PLOS Medicine found that higher intakes of carrageenan and mono- and diglycerides of fatty acids were associated with higher risks of cancer. The study observed 92,000 French adults for an average of 6.7 years.

A study published in September 2023 in The BMJ, formerly known as the British Medical Journal, found that intake of several types of emulsifiers was associated with the risk of cardiovascular disease. The study observed more than 95,000 French adults for a median of 7.4 years.

A series of earlier studies found that emulsifiers “can promote chronic intestinal inflammation in mice”; that two in particular, carboxymethyl cellulose and polysorbate 80, “profoundly impact intestinal microbiota in a manner that promotes gut inflammation and associated disease states”; and that, based on a laboratory study of human samples, “numerous, but not all, commonly used emulsifiers can directly alter gut microbiota in a manner expected to promote intestinal inflammation,” as recounted in a 2021 paper in the journal Microbiome.

Other findings diverge. A study from Australia, published in February in Alimentary Pharmacology and Therapeutics, followed 24 Crohn’s patients over four weeks and concluded that, in the context of a healthy diet, the emulsifier content had “no influence over disease activity.”

The authors declared conflicts of interest, including payments from PepsiCo, drug companies, and Mindset Health Pty, which promotes hypnosis-based therapy. One of the authors, gastroenterology professor Peter Gibson of Monash University in Australia, said the conflicts of interest “have nothing whatsoever to do with the study.”

“It is important not to overinterpret results of studies,” he said, adding that his team’s report “does not mean that emulsifiers are good for you or that there are no health benefits in avoiding emulsifiers.”

Häagen-Dazs ‘Keeps It Real’

Häagen-Dazs touts the absence of such chemicals as a virtue. “Keeping it real, the way it should be,” it said in an online plug for its vanilla ice cream. “No emulsifiers. No stabilizers.”

However, at the company that makes Häagen-Dazs in the United States, Dreyer’s Grand Ice Cream, there are limits to that approach.

Under other brand names — such as Edy’s, Dreyer’s, and Drumstick — it markets products that contain emulsifiers or stabilizers. The company did not respond to questions. In addition, a spokesperson for Nestlé, which markets Drumstick and Häagen-Dazs brands internationally, did not respond.

Drumstick Vanilla Caramel Sundae Cones have no artificial flavors or colors, the package says — but they feature an array of other ingredients, including soy lecithin, guar gum, monogylcerides, and carob bean gum.

The cones, the company’s website says, offer “one incredibly creamy experience.”

But the creamy filling doesn’t melt. Instead, over 24 hours on a KFF Health News reporter’s kitchen counter, it bled a caramel-tinged fluid and shrank into a sticky white foam that could be cut with a knife.

Cactus-Like Plant Shows Promise as Treatment for Intractable Cancer Pain

By Pat Anson

Throughout history, humans have often turned to plants and herbs for pain relief. Poppy plants gave us opium, aspirin was derived from willow trees, and peppermint oil is used to relieve everything from migraines to joint pain. Turmeric, ginger, lavender, eucalyptus and capsaicin are staples in many topical analgesics.

Researchers at the National Institutes of Health (NIH) say a cactus-like shrub native to Morocco also shows promise as a treatment for severe cancer pain and other types of intractable pain.

In a small pilot study recently published in the journal NEJM Evidence, they reported that injections of resiniferatoxin (RTX), a molecule derived from resin spurge (Euphorbia resinifera), provided durable pain relief to patients with terminal end-stage cancer.

"The effects are immediate," lead author Andrew Mannes, MD, chief of the NIH Clinical Center Department of Perioperative Medicine, said in a press release. "This is a potential new therapy from a new family of drugs that gives people with severe cancer pain an opportunity to return some normality to their lives."

The study involved 19 patients with terminal end-stage cancer who did not get adequate pain relief from opioids and other pharmaceutical drugs. But after a single injection of RTX, their worst pain intensity fell by 38% and their use of opioids by 57%. Quality of life also improved, allowing the patients to reengage with family and friends in their final days.

NIH scientists believe RTX has the potential to treat other pain conditions, including other types of cancer pain, neuropathy, post-surgical pain, trigeminal neuralgia, and chronic nerve pain caused by chemotherapy.

"Targeting specific nerves brings many pain disorders into the range of RTX and allows physicians to tailor the treatment to the patient's pain problem. This interventional approach is a simple path to personalized pain medicine," said senior author Michael Iadarola, PhD, a research scientist in the NIH Clinical Center Department of Perioperative Medicine.

RTX acts similarly to capsaicin, the active molecule in chili pepper, by numbing nerve fibers in damaged tissue and blocking them from sending pain signals to the brain. RTX enters the TRPV1 ion channel in the peripheral nervous system, allowing an overload of calcium to flood into the nerve fiber. Patients are still able to feel mild sensations like touch, pressure and pin pricks, but more severe pain signals are blocked.

"Basically, RTX cuts the pain-specific wires connecting the body to the spinal cord, but leaves many other sensations intact," Iadarola said. "These TRPV1 neurons are really the most important population of neurons that you want to target for effective pain relief."

"What makes this unique from all the other things that are out there is that it is so highly selective," Mannes said. "The only thing it seems to take out is heat sensation and pain."

People in North Africa knew this thousands of years ago. The first written record of Euphorbia resinifera being used for pain control dates back to the time of the Roman Emperor Augustus, when dried latex from the plant was used as medicine.

The NIH is planning further studies of RTX in clinical trials.

A Non-Alcoholic Drink Can Help You Relax, Socialize and May Even Relieve Pain

By Madora Pennington

I am going for a month without drinking, not because I have a problem with alcohol or because alcohol is interfering with my life. I don't and it isn't.

I just got back from a long vacation, which included an 8-day all-inclusive cruise. We wanted to get our money’s worth. After weeks of drinking every day, it seemed only sensible to take a full break from alcohol. No one would argue that so much drinking is healthy.

I am not alone. You may have heard about the “sober curious” — those who abstain to see what socializing, stress, and life itself is like without alcohol. Young adults, overall, are drinking less alcohol. These trends are fueling the demand for non-alcoholic, yet interesting drinks that seem sophisticated or reminiscent of a cocktail.

But is there a non-alcoholic drink that also helps you relax and socialize? I found a company, Sentia Spirits, that makes beverages that enhance your body’s production of GABA

Don’t confuse GABA (gamma-aminobutyric acid) with the nerve pain medication gabapentin (Neurontin). GABA is a naturally occurring neurotransmitter that sends signals in the brain and spinal cord, while gabapentin is a synthetic variation of GABA. The medication acts similarly as GABA, but tends to cause many unwanted side effects. Benzodiazepines, SSRI antidepressants, muscle relaxers, and other drugs also affect GABA in the body.

Sentia’s beverages contain herbs and botanicals that improve mood, focus, calmness, and energy. Their concoctions taste more like bitters than a mocktail, but certainly provide an interesting experience for the palate.

I found them to be subtly relaxing, without the impairment of an alcohol-induced buzz.

GABA itself is also available in supplements that people take to relax and improve sleep. It may also help relieve pain. When GABA binds to pain receptors, it reduces the transmission of pain signals, potentially providing relief from various types of physical discomfort.

SENTIA SPIRITS

Research has found that low levels of GABA make it harder to keep negative emotions such as fear, anxiety and depression in check, and may also worsen chronic pain. As PNN has reported, Dr. Forest Tennant recommends GABA supplements for patients with intractable pain "to force damaged nerve tissue to correctly function and relieve pain.”  

As far as reasons for abstaining, alcohol worsens depression. And people with alcohol use disorder often have chronic pain, which means they could be self-medicating.

Using supplemental GABA or medications that promote it could be a useful strategy in managing the spiral of chronic pain on the body and brain. Many sources suggest taking GABA on an empty stomach to give it a better chance of reaching the brain.

Limiting alcohol intake might also be a wise choice for anyone. Certainly, finding ways to diminish stress and improve sleep should be part of pain management.

Sentia costs about $40 for a 500ml bottle, which is enough for 20 shot-sized servings. If you don't want it straight or want to make it look like a cocktail, you can mix it with tonic water.

Talk to your healthcare provider about your pain control regimen and how to improve it before taking GABA or any supplement.

I enjoyed my time of sobriety very much. I thought I would miss drinking, but did not. The sleepiness and haziness from a glass of wine is stronger than I realized, and it doesn’t make socializing more fun for me. I ended my sober curious time with a resolve to drink less overall.

Care and Control of Adhesive Arachnoiditis Depends on Water

By Dr. Forest Tennant

Chronic illness tends to decrease one’s desire to drink fluids. If you have Adhesive Arachnoiditis (AA), however, you must drink some fluids about every 2 hours while awake. Why?

AA is an inflammatory disease of the spinal canal in which cauda equina nerve roots become attached by adhesions to the arachnoid-dural membranes covering the spinal canal. 

The arachnoid membrane is unique among tissues in the body as it doesn’t have its own blood supply. No arteries feed into it. Consequently, it depends on a “full tank” of spinal fluid that comes from the fluids you drink. Spinal fluid brings nutrients and medication to the arachnoid. It also bathes the inflamed area and washes away inflammatory waste and toxins.

Spinal fluid must be constantly kept at a high level. The body makes about 500 milliliters (17 ounces) of spinal fluid a day. If you are dehydrated due to lack of regular fluid intake, you may not make enough spinal fluid to control AA, including its pain.

Water Soak Every Day

Soaking in water daily is also important to control pain and inflammation from AA.

Water soaking is an age-old remedy for pain that is still worthwhile. It is believed to relieve pain by relaxing muscles and increasing blood flow to damaged areas of the body.  

Water soaking also extracts excess bioelectricity and inflammatory toxins that have accumulated due to inflammation and damage to the neurologic circuitry in the body. 

Here is a list of water soaking measures that are applicable to a person with AA: 

1. Stand in the shower and let water flow off your back, neck and legs.

2. Immerse your body up to your neck in a bathtub, hot tub, jacuzzi or pool.

3. Drape a warm, water-soaked towel over your back.

4. Soak your feet and ankles in warm water.

The soaks should be done for 5 to 15 minutes. Minerals or herbs can be put in foot baths. The most popular mineral preparation is Epsom Salts.
