TOPLINE:

Tapering glucocorticoids (GCs) does not increase the risk for flare in modified serologically active clinically quiescent (mSACQ) patients with systemic lupus erythematosus (SLE) with a low daily exposure to GC.

METHODOLOGY:

• Previous research has indicated that SACQ SLE is associated with an increased risk for flare after low-dose GC withdrawal.
• Researchers assessed the risk for flare and damage accrual after tapering GCs in mSACQ patients with SLE.
• They used data from the Asia Pacific Lupus Collaboration (APLC) to study 1850 patients (mean age, 40 years; 91.6% women) who met the criteria for SLE, including the definition of mSACQ at least once during observation and being followed up for 2 years after the first mSACQ visit.
• mSACQ was defined as a condition with serological activity but without clinical activity managed with ≤ 7.5 mg/d of -equivalent GCs, regardless of duration.
• The primary outcome was disease flare (both severe and overall) on the basis of the SELENA-SLEDAI flare index definitions.

TAKEAWAY:

• A total of 742 patients experienced an overall flare, 271 experienced a severe flare, and 180 experienced damage accrual.
• Reducing the prednisolone-equivalent GC dosage by 1 mg/d did not increase the risk for an overall (P = .27) or severe (P = .11) flare in patients initially on prednisolone-equivalent GC dosages of 0-7.5 mg/d.
• Antimalarial use decreased the risk for overall (hazard ratio [HR], 0.78; P = .002) and severe (HR, 0.59; P < .001) flares, and immunosuppressant use decreased the risk for severe flares (HR, 0.77; P = .043) but not overall flares.
• Reducing the GC dosage by 1 mg/d reduced the risk for damage accrual by 4% in patients who started taking prednisolone at a dose > 5 but ≤ 7.5 mg/d (P = .007).

IN PRACTICE:

“Cautious tapering of GCs is a feasible option for mSACQ-SLE with low daily exposure to GCs (≤ 7.5 mg/d of prednisolone-equivalent) and can reduce GC burden,” wrote the authors.

SOURCE:

The study, led by Yasuhiro Katsumata, Division of Rheumatology, Tokyo Women’s Medical University School of Medicine, Tokyo, Japan, was published online in Annals of the Rheumatic Diseases.

LIMITATIONS:

The data were collected retrospectively. A short follow-up duration might have prevented the demonstration of clear benefits in terms of damage accrual among patients receiving < 5 mg of GCs. Moreover, the findings may have limited generalizability as the majority of patients had Asian ancestry.

DISCLOSURES:

This work was supported by grants and funding from AstraZeneca, Bristol-Myers Squibb, Eli Lily, Janssen, Merck Serono, UCB, GlaxoSmithKline, Australia, and others to APLC. Some of the authors declared receiving honoraria, consulting fees, research grants, and research support from various sources.

TOPLINE:

Changes in plasma growth hormone mediators such as growth hormone receptor (GHR) and insulin-like growth factor-binding protein 1 (IGFBP-1) were associated with glycemic failure in youth-onset type 2 diabetes (T2D), an analysis of the TODAY trial showed.

METHODOLOGY:

• In youth, T2D often occurs during or after puberty, hinting at hormonal influences in the development and/or progression of the disease.
• This secondary analysis assessed the role of growth hormone mediators including insulin-like growth factor-1 (IGF-1), GHR, and IGFBP-1 in glycemic failure in a subset of 398 youths, aged 10-17 years, with a T2D duration of less than 2 years (62% girls; 21% White).
• The participants were followed up for a mean of 3.9 years.
• The primary outcomes included glycemic failure, defined as an A1c level of 8% or more for 6 months, or acute metabolic decompensation requiring insulin.
• Other assessments included baseline and 36-month measures of glycemia, insulin sensitivity, high molecular weight adiponectin, and beta cell function.

TAKEAWAY:

• Of 398 participants, 182 (46%) experienced glycemic failure, while 216 (54%) retained glycemic control.
• At 36 months, youths with glycemic failure had lower IGF-1 levels (P < .001) and higher log₂ GHR (P = .03) and log₂ IGFBP-1 (P = .009) levels than those who maintained glycemic control.
• A greater increase in IGF-1 level at 36 months was associated with lower odds of glycemic failure (odds ratio [OR], 0.995; P < .001).
• Increased levels of log₂ GHR and log₂ IGFBP-1 were associated with higher odds of glycemic failure (OR, 1.75; P = .04 and OR, 1.37; P = .007, respectively). Results were adjusted for body mass index (BMI), suggesting that associations between GHR level and glycemic outcomes exist independent of BMI.
• Interhormonal correlations suggested an association between glucose metabolism and growth hormone signaling or a shared process leading to changes in both processes.

IN PRACTICE:

“Our study has identified GHR level as a novel biomarker of decrease in glycemic control in youths with T2D,” the study authors wrote. Future research is needed, with an emphasis on assessing alterations in growth hormone mediators which may contribute to diabetes complications in youth.

SOURCE:

The study, published online in JAMA Network Open, was led by Chang Lu, MD, Division of Endocrinology, Boston Children’s Hospital, and Joslin Diabetes Center at Harvard Medical School, Boston, Massachusetts.

LIMITATIONS:

The study did not include a control group (individuals without diabetes). The cohort largely included youth in late puberty or after puberty, affecting subgroup analysis. Moreover, only circulating growth hormone mediators were measured, limiting the identity of the source tissue of the hormone and the target organs.

DISCLOSURES:

Some authors reported receiving grants from the National Institutes of Health and National Institute of Diabetes and Digestive and Kidney Diseases while conducting the study. Also, certain authors reported receiving grants and personal fees from various trusts as well as pharmaceutical, healthcare, and medical technology companies outside the submitted work.

TOPLINE:

Obstructive sleep apnea (OSA) is associated with a significantly higher risk for stroke — regardless of continuous positive airway pressure (CPAP) device use — but only in White individuals, new data suggested. The study also found that stroke risk among Black individuals with OSA was lower in those who used CPAP machines vs those who didn›t.

METHODOLOGY:

• Researchers used data on 22,192 people from the Reasons for Geographic and Racial Differences in Stroke study, a US population-based cohort of Black and White individuals with no history of stroke at baseline (mean age, 64 years; 38% Black individuals).
• 11% of overall participants had provider diagnosed OSA at baseline.
• Participants were followed for a mean of 12 years.
• Researchers adjusted for demographic, socioeconomic, and stroke risk factors.

TAKEAWAY: 

• During the follow-up period, 969 participants (4.4%) experienced a stroke.
• After adjusting for confounders, having high OSA risk and diagnosed OSA were associated with higher risks for incident stroke in White individuals (adjusted hazard ratio [aHR], 1.22; 95% CI, 1.01-1.47 and aHR, 1.33; 95% CI, 1.04-1.70, respectively) but not in Black individuals.
• Among those with diagnosed OSA, CPAP use was associated with a higher risk for incident stroke in White individuals (aHR, 1.38; 95% CI, 1.05-1.80) but a lower stroke risk in Black individuals (aHR, 0.36; 95% CI, 0.14-0.90) compared with no CPAP use.Snoring was not associated with incident stroke in either Black or White individuals.
• Snoring was not associated with incident stroke in either Black or White individuals.

IN PRACTICE:

“These results were not what we were expecting to find since Black people have been shown to have a higher risk of stroke and are more likely to have sleep apnea than White people,” lead author Rebecca Robbins, MMSc, PhD, of Brigham and Women’s Hospital in Boston, Massachusetts, said in a news release. “Since it has been shown that Black people have more severe sleep apnea than White people and take longer to be screened and treated than White people, it’s possible that using a CPAP machine provides a greater benefit on reducing stroke risk for Black people.”

SOURCE:

Robbins was the lead and corresponding author of the study. It was published online in Neurology. 

LIMITATIONS:

The current study assessed only self-reported OSA symptoms, risk, diagnosis, and treatment and did not include data on the hours of CPAP usage at night, number of days of treatment, adherence during the follow-up period, and OSA severity. 

DISCLOSURES:

The study was funded by the National Institute of Neurological Disorders and Stroke and the National Institute on Aging. Robbins received consulting income from Sonesta Hotels International, Oura Ring Ltd., Savoir Beds Ltd., Castle Hot Springs, and ByNacht GmbH.

This transcript has been edited for clarity.

Rachel S. Rubin, MD: I’m Dr. Rachel Rubin, urologist and sexual medicine specialist in the Washington, DC, area. We are coming to you live from the Mayo Clinic Urology Conference in Maui, Hawaii, with the world’s leading experts in men’s health, sexual health, and quality of life. I’m bringing in Dr. Allen Morey from the North Dallas area, one of the world’s leading experts in reconstructive urology. He deals with all things urinary incontinence, penile curvature, and sexual health.

Dr. Morey said something at this conference that really put my chin on the floor. He said, “The urethra is a sex organ. It is androgen dependent.” This is so important because it’s true for all genders. So, Dr. Morey, tell us more about why you made that comment and about the incontinence in men that you deal with all the time.

Allen F. Morey, MD: For many years, I’ve worked at cancer centers where, through the various treatments for prostate cancer, the men suffered from urinary incontinence and we put a lot of artificial urinary sphincters in those patients. I had one patient who asked, “Why do I keep having this erosion?” Of course, the erosion is where the cuff compresses the tissue surrounding the urethra, and the tissue gives way, leaving a hole in the urethra. I looked at him and noticed that he was pale. And I thought, Let me check his testosterone level. We started checking it on everybody who had this problem, and sure enough, the ones who had the cup erosion — who had the atrophic tissue around the urethra — most of them had low testosterone levels. Some of this was due to the cancer treatment, but in other men, it was just due to old age.

We started thinking that this is a causal relationship. And we tested it. I had a fellow who was a board-certified pathologist before becoming a urologist. He obtained some specimens from the urethra and did very sophisticated, elegant stains on that tissue. We found that it’s just erectile tissue surrounding the urethra. That’s why I call it a sex organ. I tell my patients, “When you are a teenager, this tissue is thin, like on your pinky finger. As you get older, it becomes thicker. And then as you get even older, and you may be having cancer treatment, that tissue is gone.” You can show them your little finger; it’s about that size. All the meat is off the bone. There’s nothing left protecting the urinary mucosa from the device.

That’s why it’s important to maintain the optimal health of those tissues and for them to remain dry. Because let’s face it: Urinary incontinence is a horrible quality of life. These are my happiest patients when we fix it. Before that, when they go on vacation, they have a separate suitcase filled with diapers. They can’t go anywhere. They can’t do anything. When they become incontinent after the prostatectomy, they gain weight. And when you put in the device to treat it, they lose weight and you can track it. The urinary incontinence patients really suffer. And we need to consider the medical optimization of those patients.

Dr. Rubin: It’s so important, and I love how analogous this is to our female patients. We know that incontinence is devastating to our female patients as well, and there’s a lot of hope. As we get older we start to pee every time we cough, laugh, or sneeze. Men are a little more bothered by it when it happens; they don’t expect it. Among women, it’s thought of as normal, but it’s not normal. There is so much we can do to help these patients, ranging from conservative treatment to surgical therapies.

The connection between hormones and urethral health is true on the female side as well. As you go through menopause, the urethral tissue thins out, gets dry, gets irritated, and can cause worsening incontinence, pain with sex, and genital urinary syndrome of menopause. It’s really important.

For our primary care doctors, how should we talk about stress incontinence in men? How do we diagnose it?

Dr. Morey: It’s easy to diagnose. Just do a quick history. Find out how many pads a day they are using. You have to ask the question, and then you have them stand up and look inside their underwear. You’ll see what kind of pad they are wearing. Is it just a shield or are they actually wearing full diapers? Then I have them do a standing cough test. I stand off to the side, holding a couple of towels, and have the patient cough four times. I can tell if it’s a full stream or just a couple of drops. Is it nothing but they are wearing a pad? You match up what you see with their experience, and in an instant it tells you how severe their problem is and it helps you direct them on to further treatment, because many patients have treatment fatigue. They’ve already been through the system. They have really suffered and they don’t know which way to go. They don’t know what’s available.

Dr. Rubin: On the female side, we have pelvic floor physical therapy. We have pads and devices that you can wear, and pessaries. We have surgical options, like bulking agents into the urethra as well as urethral slings, which can be quite helpful for women. So there’s a lot of hope out there for women, and from what I learned from you at this conference, there’s a lot of hope for men as well. So talk us through treatment, from conservative to surgical options.

Dr. Morey: There hasn’t been much innovation in male incontinence treatment over the past few decades, but we’re starting to see signs of new products appearing on the horizon, so I’m very optimistic that in the next 5 or 10 years, we’ll have more. But right now it comes down to slings and artificial sphincters, which are devices with little pumps and hydraulics, and they’re very good. But they’ve been around for 50 years, and they have this other potential risk factor of the erosion of the tissue.

We don’t have a pill that we can give the patient to tighten up those muscles. We can help them with overactive bladder. But maybe the hormonal influence is a way to optimize the health of the tissue so that these surgical treatments can really deliver the best outcomes. And as I always say, and having treated so many of these patients, it’s really a game of millimeters — how much coaptation you get. If you’re off by the slightest amount, that’s an unhappy patient. So it doesn’t take much to make it a lot better.

Dr. Rubin: There’s so much hope for our patients, and this can really have an effect on sexual health. You know the benefits you see in their quality of life and sexual health when you can stop leakage.

Dr. Morey: I always take care of the waterworks first. Many of the men have both urinary problems and erectile problems. Nobody feels sexy when they’re leaking urine all over their partner. So first we take care of that. And then, in the motivated younger patients, we bring them back and talk to them about potentially having a second operation.

Dr. Rubin: And so similarly, in women with urinary incontinence, it can have a major impact on sexual health — how they show up and how they talk to their partner. So, it is really important for our primary care docs to talk to patients about urinary incontinence and not just say, “Oh, well, you’re getting older. There’s nothing that you can do.” There’s actually no age at which there is nothing that we can do. And it’s really important to refer patients to those urologists who have extra training in incontinence and sexual health, because we do care about these quality-of-life measures and there is a lot we can do, ranging from conservative to more invasive treatments. But patients really should have options.

Dr. Morey: I heard during this meeting that urinary incontinence was the number-one source of treatment regret among patients who had their prostate treated for cancer. So, this is a really big deal for our patients. And it impacts wellness, quality of life, and overall well-being.

Dr. Rubin: When we are counseling patients for cancer surgeries or cancer treatments such as radiation therapy, it’s really hard for the patients who have never had urinary incontinence to imagine what that might be like. When you’re telling them they could have a stroke or a heart attack, or they could have erectile dysfunction or urinary incontinence, it all sounds similar to them. It could happen to someone else. It’s very hard to truly counsel patients on these quality-of-life issues that they’ve never encountered before.

Dr. Morey: We have found that it takes a long time for patients to get into our office for treatment, and it’s unbelievable — often 5 years in diapers before they find us.

Dr. Rubin: Hopefully videos like this will teach our docs and our patients that there is hope out there, that you don’t need to wait through years of suffering from incontinence. So, how does somebody find a reconstructive urologist or a sexual medicine urologist?

Dr. Morey: There are a couple of good websites out there, such as fixincontinence.com and edcure.org. The device manufacturers have pretty good information for patients.

Dr. Rubin: The Sexual Medicine Society of North America (SMSNA) has a great find-a-provider website, which provides a list of urologists who are trained in both sexual health and urinary incontinence, because they both matter. Our patients deeply care about these issues.

Rachel S. Rubin, MD: I’m Dr. Rachel Rubin, urologist and sexual medicine specialist in the Washington, DC, area. We are coming to you live from the Mayo Clinic Urology Conference in Maui, Hawaii, with the world’s leading experts in men’s health, sexual health, and quality of life. I’m bringing in Dr. Allen Morey from the North Dallas area, one of the world’s leading experts in reconstructive urology. He deals with all things urinary incontinence, penile curvature, and sexual health.

Dr. Morey said something at this conference that really put my chin on the floor. He said, “The urethra is a sex organ. It is androgen dependent.” This is so important because it’s true for all genders. So, Dr. Morey, tell us more about why you made that comment and about the incontinence in men that you deal with all the time.

Allen F. Morey, MD: For many years, I’ve worked at cancer centers where, through the various treatments for prostate cancer, the men suffered from urinary incontinence and we put a lot of artificial urinary sphincters in those patients. I had one patient who asked, “Why do I keep having this erosion?” Of course, the erosion is where the cuff compresses the tissue surrounding the urethra, and the tissue gives way, leaving a hole in the urethra. I looked at him and noticed that he was pale. And I thought, Let me check his testosterone level. We started checking it on everybody who had this problem, and sure enough, the ones who had the cup erosion — who had the atrophic tissue around the urethra — most of them had low testosterone levels. Some of this was due to the cancer treatment, but in other men, it was just due to old age.

We started thinking that this is a causal relationship. And we tested it. I had a fellow who was a board-certified pathologist before becoming a urologist. He obtained some specimens from the urethra and did very sophisticated, elegant stains on that tissue. We found that it’s just erectile tissue surrounding the urethra. That’s why I call it a sex organ. I tell my patients, “When you are a teenager, this tissue is thin, like on your pinky finger. As you get older, it becomes thicker. And then as you get even older, and you may be having cancer treatment, that tissue is gone.” You can show them your little finger; it’s about that size. All the meat is off the bone. There’s nothing left protecting the urinary mucosa from the device.

That’s why it’s important to maintain the optimal health of those tissues and for them to remain dry. Because let’s face it: Urinary incontinence is a horrible quality of life. These are my happiest patients when we fix it. Before that, when they go on vacation, they have a separate suitcase filled with diapers. They can’t go anywhere. They can’t do anything. When they become incontinent after the prostatectomy, they gain weight. And when you put in the device to treat it, they lose weight and you can track it. The urinary incontinence patients really suffer. And we need to consider the medical optimization of those patients.

Dr. Rubin: It’s so important, and I love how analogous this is to our female patients. We know that incontinence is devastating to our female patients as well, and there’s a lot of hope. As we get older we start to pee every time we cough, laugh, or sneeze. Men are a little more bothered by it when it happens; they don’t expect it. Among women, it’s thought of as normal, but it’s not normal. There is so much we can do to help these patients, ranging from conservative treatment to surgical therapies.

The connection between hormones and urethral health is true on the female side as well. As you go through menopause, the urethral tissue thins out, gets dry, gets irritated, and can cause worsening incontinence, pain with sex, and genital urinary syndrome of menopause. It’s really important.

For our primary care doctors, how should we talk about stress incontinence in men? How do we diagnose it?

Dr. Morey: It’s easy to diagnose. Just do a quick history. Find out how many pads a day they are using. You have to ask the question, and then you have them stand up and look inside their underwear. You’ll see what kind of pad they are wearing. Is it just a shield or are they actually wearing full diapers? Then I have them do a standing cough test. I stand off to the side, holding a couple of towels, and have the patient cough four times. I can tell if it’s a full stream or just a couple of drops. Is it nothing but they are wearing a pad? You match up what you see with their experience, and in an instant it tells you how severe their problem is and it helps you direct them on to further treatment, because many patients have treatment fatigue. They’ve already been through the system. They have really suffered and they don’t know which way to go. They don’t know what’s available.

Dr. Rubin: On the female side, we have pelvic floor physical therapy. We have pads and devices that you can wear, and pessaries. We have surgical options, like bulking agents into the urethra as well as urethral slings, which can be quite helpful for women. So there’s a lot of hope out there for women, and from what I learned from you at this conference, there’s a lot of hope for men as well. So talk us through treatment, from conservative to surgical options.

Dr. Morey: There hasn’t been much innovation in male incontinence treatment over the past few decades, but we’re starting to see signs of new products appearing on the horizon, so I’m very optimistic that in the next 5 or 10 years, we’ll have more. But right now it comes down to slings and artificial sphincters, which are devices with little pumps and hydraulics, and they’re very good.

Nearly 18 months after the US Food and Drug Administration (FDA) first acknowledged a national shortage of Adderall, the most common drug used to treat attention-deficit/hyperactivity disorder (ADHD), there is now a widespread scarcity of other stimulant medications — with no end in sight. How did this crisis develop and what measures are underway to address it?

The first shortage of immediate release formulations of amphetamine mixed salts (Adderall, Adderall IR) was reported by the FDA in October 2022. Now, the list includes Focalin, Ritalin, and Vyvanse, among others.

Adding to the ongoing crisis, the FDA announced in early February that Azurity Pharmaceuticals was voluntarily withdrawing one lot of its Zenzedi (dextroamphetamine sulfate) 30 mg tablets because of contamination with the antihistamine, carbinoxamine.

For the roughly 10 million adults and 6 million children in the United States grappling with ADHD, getting a prescription filled with the exact medication ordered by a physician is dictated by geographic location, insurance formularies, and pharmacy supply chains. It’s particularly challenging for those who live in rural or underserved areas with limited access to nearby pharmacies.

“Not a day goes by when I don’t hear from a number of unfortunately struggling patients about this shortage,” said Aditya Pawar, MD, a child and adolescent psychiatrist with the Kennedy Krieger Institute and an assistant professor of psychiatry and behavioral sciences at Johns Hopkins School of Medicine, Baltimore, Maryland.

The ADHD drug shortage is now well into its second year, and clinicians and advocates alike say there is no apparent end in sight.

How Did We Get Here?

Manufacturers and federal agencies blame the shortage on rising demand and each other, while clinicians say that insurers, drug distributors, and middlemen are also playing a role in keeping medications out of patients’ hands.

In August 2023, the Drug Enforcement Administration (DEA), which sets quotas for the production of controlled substances, and the FDA publicly blamed manufacturers for the shortages, claiming they were not using up their allocations.

At the time, the DEA said manufacturers made and sold only 70% of their quota, nearly 1 billion doses short of what they were allowed to produce and ship that year.

The agencies also noted a record-high number of prescriptions for stimulants from 2012 to 2021. Driven in part by telehealth, the demand intensified during the pandemic. One recent study reported a 14% increase in ADHD stimulant prescriptions between 2020 and 2022.

Insurers also play a role in the shortage, David Goodman, MD, an assistant professor of psychiatry and behavioral sciences also at Johns Hopkins University, told this news organization.

Stepped therapy — in which patients must try one, two, or three medications before they are authorized to receive a more expensive or newer drug — contributes to the problem, Dr. Goodman said. Demand for such medications is high and supply low. In addition, some insurers only provide coverage for in-network pharmacies, regardless of the ability of other providers outside such networks to fill prescriptions.

“If the insurance dictates where you get your pills, and that pharmacy doesn’t have the pills or that pharmacy chain in your area doesn’t have those pills, you’re out of luck,” Dr. Goodman said.

Patients as Detectives

To get prescriptions filled, patients must “turn into detectives,” Laurie Kulikosky, CEO of Children and Adults with Attention-Deficit/Hyperactivity Disorder, told this news organization. “It’s a huge stressor.”

Tracking which ADHD medications are available, on back order, or discontinued requires frequent checking of the FDA’s drug shortages website.

Some manufacturers of generic versions of mixed amphetamine salts are only fulfilling orders for existing contracts, while others say new product won’t be available until at least April or as late as September. All blame the delay on the shortage of active ingredients.

Teva, which makes both the brand and generic of Adderall, reported on the FDA’s site that its manufacturing and distribution is at record-high levels, but demand continues to rise.

The branded Concerta is available, but some makers of generic methylphenidate reported supplies won’t be available until July.

Lisdexamfetamine dimesylate in almost all dosages is either unavailable, available in restricted quantities, or on extended back order. However, the branded product Vyvanse is available.

Industry, Government Respond

In a November 2023 statement, the DEA reported that 17 of 18 drug manufacturers the agency contacted planned to use their full DEA quota and increase production for that year. The agency said it had made it easier for manufacturers to request changes in allocations and that periodically updating quotas was a possibility.

This news organization asked the DEA whether any manufacturers had not met their 2023 quotas, but an agency spokesperson said it would not comment.

An FDA spokesperson said it could help manufacturers ask for bigger quotas and to increase production, noting that in 2023, the DEA increased the quota for methylphenidate following an FDA request.

“The FDA is in frequent communication with the manufacturers of ADHD stimulant medications and the DEA, and we will continue to monitor supply,” the spokesperson said.

For 2024, the FDA told the DEA that it predicted a 3.1% increase in use of amphetamine, methylphenidate (including dexmethylphenidate), and lisdexamfetamine. The DEA took that into account when it issued its final quotas for 2024. Whether those amounts will be enough remains to be seen.

With many drugs — not just those for ADHD — in short supply, in February, the US Department of Health and Human Services (HHS) and the Federal Trade Commission opened an inquiry of sorts, seeking comments on how middlemen and others were influencing pricing and supply of generic drugs.

“When you’re prescribed an important medication by your doctor and you learn the drug is out of stock, your heart sinks,” HHS Secretary Xavier Becerra said in a statement. “This devastating reality is the case for too many Americans who need generic drugs for ADHD, cancer, and other conditions.”

On the comments site, which is open until April 15, many of the 4000-plus complaints filed to-date are from individuals with ADHD.

Dr. Pawar said clinicians can’t know what’s going on between the FDA, the DEA, and manufacturers, adding that, “they need to sit together and figure something out.”

Even Members of Congress have had trouble getting answers. In October, Rep. Abigail Spanberger (D-Virginia) and a dozen colleagues wrote to the FDA and DEA seeking information on how the agencies were responding to stimulant shortages. The DEA has still not replied.

Workarounds the Only Option?

In the past, physicians would prescribe the optimal medication for individual patients based on clinical factors. Now, one of the major factors in determining drug choice is the agent that has “the highest likelihood of benefit and the lowest likelihood of administrative demand or burden,” Dr. Goodman said.

With so many medications in short supply, clinicians have figured out workarounds to get prescriptions filled, but they don’t often pan out.

If a patient needs a 60-mg daily dose of a medication and the pharmacy doesn’t have any 60-mg pills, Dr. Goodman said he might write a prescription for a 30-mg pill to be taken twice a day. However, insurers often will cover only 30 pills for a month, which can thwart this strategy.

Dr. Pawar said he sometimes prescribes Journay PM in lieu of Concerta because it is often available. But insurers may deny coverage of Journay PM because it is a newer medication, he said. When prescribing ADHD medications, he also provides his patients with a list of potential substitutes so they can ask the pharmacist if any are in stock.

With no end to the shortage in sight, clinicians must often prescribe multiple medications until their patients are able to find one that’s available. In addition, patients are burdened with making calls and visits to multiple pharmacies until they find one that can fill their prescription.

Meanwhile, the ripple effects to the ADHD drug shortage continue to spread. Extended periods without treatment can lead to declining job performance or job loss, fractured relationships, and even financial distress, Dr. Goodman said.

“If you go without your pills for a month and you’re not performing, your work declines and you lose your job as a result, that’s not on you — that’s on the fact that you can’t get your treatment,” he noted. “The shortage is no longer an inconvenience.”

Dr. Goodman, Dr. Pawar, and Ms. Kulikosky reported no relevant financial relationships.

Stepped therapy — in which patients must try one, two, or three medications before they are authorized to receive a more expensive or newer drug — contributes to the problem, Dr. Goodman said. Demand for such medications is high and supply low. In addition, some insurers only provide coverage for in-network pharmacies, regardless of the ability of other providers outside such networks to fill prescriptions.

“If the insurance dictates where you get your pills, and that pharmacy doesn’t have the pills or that pharmacy chain in your area doesn’t have those pills, you’re out of luck,” Dr. Goodman said.

Patients as Detectives

To get prescriptions filled, patients must “turn into detectives,” Laurie Kulikosky, CEO of Children and Adults with Attention-Deficit/Hyperactivity Disorder, told this news organization. “It’s a huge stressor.”

Tracking which ADHD medications are available, on back order, or discontinued requires frequent checking of the FDA’s drug shortages website.

Some manufacturers of generic versions of mixed amphetamine salts are only fulfilling orders for existing contracts, while others say new product won’t be available until at least April or as late as September. All blame the delay on the shortage of active ingredients.

Teva, which makes both the brand and generic of Adderall, reported on the FDA’s site that its manufacturing and distribution is at record-high levels, but demand continues to rise.

The branded Concerta is available, but some makers of generic methylphenidate reported supplies won’t be available until July.

Lisdexamfetamine dimesylate in almost all dosages is either unavailable, available in restricted quantities, or on extended back order. However, the branded product Vyvanse is available.

Industry, Government Respond

In a November 2023 statement, the DEA reported that 17 of 18 drug manufacturers the agency contacted planned to use their full DEA quota and increase production for that year. The agency said it had made it easier for manufacturers to request changes in allocations and that periodically updating quotas was a possibility.

This news organization asked the DEA whether any manufacturers had not met their 2023 quotas, but an agency spokesperson said it would not comment.

An FDA spokesperson said it could help manufacturers ask for bigger quotas and to increase production, noting that in 2023, the DEA increased the quota for methylphenidate following an FDA request.

“The FDA is in frequent communication with the manufacturers of ADHD stimulant medications and the DEA, and we will continue to monitor supply,” the spokesperson said.

For 2024, the FDA told the DEA that it predicted a 3.1% increase in use of amphetamine, methylphenidate (including dexmethylphenidate), and lisdexamfetamine. The DEA took that into account when it issued its final quotas for 2024. Whether those amounts will be enough remains to be seen.

With many drugs — not just those for ADHD — in short supply, in February, the US Department of Health and Human Services (HHS) and the Federal Trade Commission opened an inquiry of sorts, seeking comments on how middlemen and others were influencing pricing and supply of generic drugs.

“When you’re prescribed an important medication by your doctor and you learn the drug is out of stock, your heart sinks,” HHS Secretary Xavier Becerra said in a statement. “This devastating reality is the case for too many Americans who need generic drugs for ADHD, cancer, and other conditions.”

On the comments site, which is open until April 15, many of the 4000-plus complaints filed to-date are from individuals with ADHD.

Dr. Pawar said clinicians can’t know what’s going on between the FDA, the DEA, and manufacturers, adding that, “they need to sit together and figure something out.”

Even Members of Congress have had trouble getting answers. In October, Rep. Abigail Spanberger (D-Virginia) and a dozen colleagues wrote to the FDA and DEA seeking information on how the agencies were responding to stimulant shortages. The DEA has still not replied.

Workarounds the Only Option?

In the past, physicians would prescribe the optimal medication for individual patients based on clinical factors. Now, one of the major factors in determining drug choice is the agent that has “the highest likelihood of benefit and the lowest likelihood of administrative demand or burden,” Dr. Goodman said.

With so many medications in short supply, clinicians have figured out workarounds to get prescriptions filled, but they don’t often pan out.

If a patient needs a 60-mg daily dose of a medication and the pharmacy doesn’t have any 60-mg pills, Dr. Goodman said he might write a prescription for a 30-mg pill to be taken twice a day. However, insurers often will cover only 30 pills for a month, which can thwart this strategy.

Dr. Pawar said he sometimes prescribes Journay PM in lieu of Concerta because it is often available. But insurers may deny coverage of Journay PM because it is a newer medication, he said. When prescribing ADHD medications, he also provides his patients with a list of potential substitutes so they can ask the pharmacist if any are in stock.

With no end to the shortage in sight, clinicians must often prescribe multiple medications until their patients are able to find one that’s available. In addition, patients are burdened with making calls and visits to multiple pharmacies until they find one that can fill their prescription.

Meanwhile, the ripple effects to the ADHD drug shortage continue to spread. Extended periods without treatment can lead to declining job performance or job loss, fractured relationships, and even financial distress, Dr. Goodman said.

“If you go without your pills for a month and you’re not performing, your work declines and you lose your job as a result, that’s not on you — that’s on the fact that you can’t get your treatment,” he noted. “The shortage is no longer an inconvenience.”

Dr. Goodman, Dr. Pawar, and Ms. Kulikosky reported no relevant financial relationships.

Nearly 18 months after the US Food and Drug Administration (FDA) first acknowledged a national shortage of Adderall, the most common drug used to treat attention-deficit/hyperactivity disorder (ADHD), there is now a widespread scarcity of other stimulant medications — with no end in sight. How did this crisis develop and what measures are underway to address it?

The first shortage of immediate release formulations of amphetamine mixed salts (Adderall, Adderall IR) was reported by the FDA in October 2022. Now, the list includes Focalin, Ritalin, and Vyvanse, among others.

Adding to the ongoing crisis, the FDA announced in early February that Azurity Pharmaceuticals was voluntarily withdrawing one lot of its Zenzedi (dextroamphetamine sulfate) 30 mg tablets because of contamination with the antihistamine, carbinoxamine.

For the roughly 10 million adults and 6 million children in the United States grappling with ADHD, getting a prescription filled with the exact medication ordered by a physician is dictated by geographic location, insurance formularies, and pharmacy supply chains. It’s particularly challenging for those who live in rural or underserved areas with limited access to nearby pharmacies.

“Not a day goes by when I don’t hear from a number of unfortunately struggling patients about this shortage,” said Aditya Pawar, MD, a child and adolescent psychiatrist with the Kennedy Krieger Institute and an assistant professor of psychiatry and behavioral sciences at Johns Hopkins School of Medicine, Baltimore, Maryland.

The ADHD drug shortage is now well into its second year, and clinicians and advocates alike say there is no apparent end in sight.

How Did We Get Here?

Manufacturers and federal agencies blame the shortage on rising demand and each other, while clinicians say that insurers, drug distributors, and middlemen are also playing a role in keeping medications out of patients’ hands.

In August 2023, the Drug Enforcement Administration (DEA), which sets quotas for the production of controlled substances, and the FDA publicly blamed manufacturers for the shortages, claiming they were not using up their allocations.

At the time, the DEA said manufacturers made and sold only 70% of their quota, nearly 1 billion doses short of what they were allowed to produce and ship that year.

The agencies also noted a record-high number of prescriptions for stimulants from 2012 to 2021. Driven in part by telehealth, the demand intensified during the pandemic. One recent study reported a 14% increase in ADHD stimulant prescriptions between 2020 and 2022.

Alzheimer’s research is plagued with misconduct and fraud, undermining the progress toward understanding and treating the disease, say investigators who endeavor to expose errors and misleading practices.

The book is yet to be closed, for instance, on whether a 2006 paper by Sylvain Lesne positing amyloid as a major cause of Alzheimer’s was based on fraudulent data. Suspicions about the paper were first raised in late 2021 by Matthew Schrag, MD, PhD, an assistant professor of neurology at Vanderbilt University Medical Center, Nashville, Tennessee.

Dr. Schrag also queried the work of a City University of New York (CUNY) researcher who proposed PT-125 (now simufilam) as a potential anti-amyloid for Alzheimer’s disease. Even though CUNY recently found “egregious” and potentially deliberate misconduct by that researcher, Cassava Sciences is continuing phase 3 trials of simufilam.

Now questions are being raised about work from the lab of Berislav V. Zlokovic, PhD, a prominent neuroscientist at the University of Southern California (USC), Los Angeles, California, and also about studies conducted under the aegis of Domenico Pratico, MD, the director of the Alzheimer’s Center at Temple University in Philadelphia, Pennsylvania.

Alzheimer’s has been a notoriously hard puzzle to solve. Despite decades of research, there are still no effective therapies and disparate theories about potential causes.

Dr. Schrag said he wouldn’t “attribute all the ills in this field” to misconduct, but it “is absolutely a part of the equation.” Some of the papers flagged for integrity issues “have been hugely influential,” he said in an interview. “Some of the labs that we’re talking about have really shaped how we’ve thought about this disease,” he said. “It’s hard to un-ring the bell.”

The fallout from fraud has a wide impact. Taxpayer dollars are wasted in the creation of the fraud and in attempts to replicate the failed experiment. Grad students — the workhorses of labs — waste time trying to repeat studies or may be bullied or intimidated into misconduct, said Elisabeth Bik, PhD, a former Stanford microbiologist who is now a full-time fraud investigator.

And there’s potential harm to patients. “There’s a lot of false hope being given to these people and their families,” Dr. Bik said in an interview.
 

Alzheimer’s Tempts With Big Rewards

There are big rewards for those who publish important papers on Alzheimer’s: More grants, publication in higher-impact journals, larger labs, and potentially, personal enrichment from commercialization of therapies.

“I can see that people are driven to cut corners or even to make up results, or even anything in between, to reach that goal,” said Dr. Bik.

It’s unclear whether misconduct and fraud are on the rise or just being detected more frequently.

“It’s very hard to say,” said Mike Rossner, PhD, president of Image Data Integrity. Institutions hire Dr. Rossner to help ferret out research integrity issues. He told this news organization that it’s likely detection is on the rise, given the increasing number of sleuths like Dr. Bik.

In 2002, Dr. Rossner began to screen all images submitted to the Journal of Clinical Biology in response to the new phenomenon of digital images and the advent of PhotoShop. “Very early on, we started to see problems in digital images that we would not have seen on a glossy printout,” Dr. Rossner said of his time as managing editor of the journal.

From 2002 to 2014, at least 25% of papers had an image that violated guidelines that prohibited the removal of spots or other blemishes (called “beautification”) with PhotoShop, which did not necessarily indicate fraud. They withdrew acceptance for 1% of papers because of image manipulations that affected data interpretation.

Dr. Bik noted that even if there is not a greater percentage of fraudulent papers in Alzheimer’s, “it would still be in absolute numbers a lot of papers that could be fraudulent,” given that Alzheimer’s research is well-funded with federal agencies alone providing $3.7 billion a year.

Images Key to Spotting Issues

Investigative sleuths often use the online forum PubPeer to initially raise questions about papers. The format gives the original authors a chance to comment on or defend their work. While some critiques are about data, most hone in on alleged duplications or manipulations of images, primarily by Western Blots.

The images are key, because “the images are the data,” said Dr. Rossner. “The words are the author’s interpretation of what they see in the images,” he said.

It’s also easier to spot a problem in an image. The raw data or an investigator’s notebooks aren’t needed, and there are artificial intelligence-driven software programs such as Proofig and Image Twin that help investigators spot duplicated images or cases in which an image might have been flipped or otherwise manipulated to make results look better.

Science recently announced that it would be using Proofig to screen images in all papers submitted to its six journals.

Using a screening tool is better than nothing, said Dr. Rossner who still relies on visual inspection, employing contrast or other features in PhotoShop to spot inconsistencies or duplications. But “none of those companies have disclosed how effective they are relative to visual screening, and that to me is very problematic,” he said.

“The tools are not going to catch everything,” said Dr. Bik.

Dr. Schrag agreed. “One of the things that we’re worried about is that a lot of the journals will simply adopt these tools as a screener and assume that that’s going to de-risk their publication portfolio,” he said, noting the high rate of misses.

Artificial Intelligence a Growing Concern

Artificial intelligence (AI) may also accelerate the amount of fraud and add to the difficulty of ferreting it out, said the investigators.

“I’m very worried about AI,” said Dr. Bik. Although AI-generated images and content may be rudimentary today, “next year it’s going to be much better,” she said. Going forward, it may be hard to distinguish between a real dataset and one that has been generated by AI, she said.

“The more closely AI can mimic authentic content, the more difficult it will be for publications to detect intentionally fraudulent submissions,” wrote Dror Kolodkin-Gal, PhD, the founder of Proofig, in an article for the Council of Science Editors.

Dr. Kolodkin-Gal said that AI may be especially prone to misuse by paper mills. Those operations submit fake or shoddy manuscripts to a journal on behalf of researchers seeking publication who pay the mills a fee. The Committee on Publication Ethics reported in 2022 that 2%-46% of papers submitted to journals may be from paper mills.

While it’s unclear whether AI is having any impact now, Dr. Rossner said, “I think I can be pretty confident in saying it is going to be a growing problem” as the tools become more sophisticated.

He sees parallels with the rise of PhotoShop and cites data from the National Institute of Health’s Office of Research Integrity (ORI) showing that in 1990, when PhotoShop was still new, 2% of cases referred to ORI involved image manipulation. By 2007, 70% of cases had image manipulation issues.

Journals, Institutions Need to Step Up More

Fraud may continue apace in part because investigations drag on for years, and in many cases, with a lack of consequences for the perpetrators, said the investigators. And, they say, journals and institutions haven’t devoted enough resources to prevent or investigate misconduct.

“A lot of editors did not even want to investigate because they just didn’t want to believe that there could be fraud in science,” said Dr. Bik of her experiences. “I hope that by now most journals at least should have realized that some proportion of the manuscripts that get sent to their journals is going to be fraud,” she said.

“The bulk of the journals seem like they don’t want to be bothered by this,” agreed Dr. Schrag, adding that “some have gone to great lengths to try to discourage people from bringing forward complaints.”

A big issue is that journals “don’t answer to any higher authority,” said Dr. Schrag. He believes that journals that repeatedly refuse to address integrity issues should be barred from publishing research produced with funds from the National Institutes of Health.

All the investigators said institutions and journals should hire forensic investigators. Relying on unpaid peer reviewers or editors to root out fraud is unrealistic, they said.

“You want to have specialized people with experience and be paid to do that as a full-time job,” said Dr. Bik, who is funded by speaking engagements and receives about $2300 a month through donations to her Patreon account.

Once a potential integrity issue is flagged, there is “an incredible conflict of interest in how these investigations are run,” said Dr. Schrag. “Institutions are asked to investigate their own faculty; they’re asked to investigate themselves.” That “creates the disincentive to move expeditiously,” said Dr. Schrag.

With the space of time, people who have committed fraud can throw out notebooks, delete data from servers, or even PhotoShop original photos so they match the manipulated ones that were submitted, Dr. Bik said.

Institutions could show they are serious about fraud by offering a “central, systematic universal screening of all image data going out of their institutions before submission to a journal,” said Dr. Rossner. But he knows only of a handful that do so. “I think research integrity offices have historically been very reactive, and they need to pivot and become proactive,” said Dr. Rossner.

Dr. Schrag wants to see stronger values within the research enterprise. “You have to build a culture where it’s absolutely anathema at a core level to violate these standards of research integrity,” he said. “We have this notion that we can push the process along faster and get to a grant and get to a paper and get to some short-term goal,” he said. “But the long-term goal in most of these cases is to cure a disease or to understand some biological mysteries. There’s no shortcut to getting there,” said Dr. Schrag.

There have been some high-profile consequences for research integrity failures, such as the 2023 resignation of Stanford University President Marc Tessier-Lavigne in the wake of findings that members of his lab — but not Tessier-Lavigne — engaged in data manipulation.

The process is often opaque, with investigations done in secrecy. “Consequences are not usually revealed, either,” said Dr. Rossner.

Dr. Schrag acknowledges it’s a tough balancing act for institutions to root out bad actors while also ensuring there’s no harm to those who may simply have operated in error.

“But it doesn’t serve anyone’s interest including the people who are accused, in dragging these things out for 5, 6, 8, or 10 years,” he said.

Lesne and Cassava: The Long and Winding Road

The investigations into the Lesne papers and the work underpinning Cassava Sciences’ therapy point to the difficulty of policing integrity and the potential fallout.

Lesne’s signature paper published in Nature in 2006 has been cited some 2300 times and is the fourth most-accessed article of 81,612 articles of a similar age in all journals tracked by Altimetrics.

Dr. Schrag, Dr. Bik, and others wrote to multiple journals asking them to investigate some 25 papers related to simufilam, including a 2012 Journal of Clinical Investigation article by Hoau-Yan Wang, PhD, the CUNY scientist whose work on simufilam has been questioned.

JCI Editor Elizabeth McNally pushed back stating in an editorial in 2022 that they, as whistleblowers, had potential conflicts and that they could be assisting short sellers who were seeking to profit by depressing Cassava’s stock price. Indeed, Dr. Schrag was initially hired by a law firm that was representing short sellers. Ms. McNally said that JCI would start requiring disclosures by whistleblowers.

Dr. Bik urged CUNY to investigate Dr. Wang in 2021 but was rebuffed. Then, in November 2023, a copy of CUNY’s final report on the Wang inquiry was leaked to Science. The university reported that Dr. Wang did not provide any original data or notebooks and that it found “long-standing and egregious misconduct in data management and record keeping by Dr. Wang,” wrote Dr. Bik in a blog post summarizing the investigation.

As of late 2023, 42 papers by Dr. Wang have earned PubPeer posts, seven have been retracted, and five have been marked with an Expression of Concern, wrote Dr. Bik.

Some have called for Cassava to stop its phase 3 studies of simufilam, but the company is proceeding, announcing in November 2023 that they have completed enrollment.

Misconduct Queries Underway at USC and Temple

Meanwhile, Dr. Schrag and Dr. Bik continue sleuthing. They are among a small group of whistleblowers who have filed a complaint with NIH about irregularities in the Zlokovic lab at USC. They allege that images were manipulated in dozens of papers, including some that inform the development of a stroke drug in phase 2 trials.

The inquiry goes well beyond stroke, said Dr. Schrag. Dr. Zlokovic “is one of the most influential scientists on Alzheimer’s scientists in the country,” Dr. Schrag said. The USC scientist is a leader on blood-brain barrier research.

USC is investigating “at some level,” he said. In a statement to this news organization, USC said that it “takes any allegations about research integrity very seriously.” The statement added, “Consistent with federal regulations and USC policies, this review must be kept confidential. As a result, we are unable to provide any further information.”

Mu Yang, PhD, assistant professor of neurobiology at Columbia University Medical Center in New York City, is also working on the Zlokovic investigation.

She calls herself an “accidental sleuth” who fell into the hobby after a graduate student asked her to help replicate a study by Temple University, Philadelphia, Pennsylvania, researcher Dominco Pratico, MD, of Alzheimer’s-like phenotype mice in the Morris Water Maze test. Dr. Yang, who runs the “behavior core” at Columbia — teaching and advising on how to run assays and collect and report data — could see right away that the Pratico data were “too perfect.”

She enlisted maze inventor Richard Morris to join her in a letter of concern to the journals that published Dr. Pratico’s work, all under the aegis of Springer Nature.

The publisher’s integrity team has since retracted four Pratico papers. Three were because of image abnormalities pointed out by Dr. Bik, who worked with Dr. Yang. One was because of “self-plagiarism.”

“The official retraction notes didn’t mention anything about data abnormality being a concern,” said Dr. Yang who says that questionable data is harder to prove than an image duplication or manipulation. And the papers remain available, although dozens of Practico papers have been flagged on PubPeer.

To Dr. Yang, images are the canary in the coalmine. “People don’t just fake western blots but then give real behavior data or give you fake behavior data but give you the most authentic Western Blots,” she said.

Dr. Pratico has now sued a graduate student who was a coauthor on the papers, according to the Philadelphia Inquirer.

The NIH’s ORI has requested that Temple University conduct an investigation, Dr. Yang said.

In a statement to this news organization, Temple said it “does not comment on internal investigations or personnel issues,” but that “allegations of research misconduct are reviewed and investigated centrally through Temple’s Office of the Vice President for Research in accordance with university policy and applicable federal regulations.”

“The tools are not going to catch everything,” said Dr. Bik.

Dr. Schrag agreed. “One of the things that we’re worried about is that a lot of the journals will simply adopt these tools as a screener and assume that that’s going to de-risk their publication portfolio,” he said, noting the high rate of misses.

Artificial Intelligence a Growing Concern

Artificial intelligence (AI) may also accelerate the amount of fraud and add to the difficulty of ferreting it out, said the investigators.

“I’m very worried about AI,” said Dr. Bik. Although AI-generated images and content may be rudimentary today, “next year it’s going to be much better,” she said. Going forward, it may be hard to distinguish between a real dataset and one that has been generated by AI, she said.

“The more closely AI can mimic authentic content, the more difficult it will be for publications to detect intentionally fraudulent submissions,” wrote Dror Kolodkin-Gal, PhD, the founder of Proofig, in an article for the Council of Science Editors.

Dr. Kolodkin-Gal said that AI may be especially prone to misuse by paper mills. Those operations submit fake or shoddy manuscripts to a journal on behalf of researchers seeking publication who pay the mills a fee. The Committee on Publication Ethics reported in 2022 that 2%-46% of papers submitted to journals may be from paper mills.

While it’s unclear whether AI is having any impact now, Dr. Rossner said, “I think I can be pretty confident in saying it is going to be a growing problem” as the tools become more sophisticated.

He sees parallels with the rise of PhotoShop and cites data from the National Institute of Health’s Office of Research Integrity (ORI) showing that in 1990, when PhotoShop was still new, 2% of cases referred to ORI involved image manipulation. By 2007, 70% of cases had image manipulation issues.

Journals, Institutions Need to Step Up More

Fraud may continue apace in part because investigations drag on for years, and in many cases, with a lack of consequences for the perpetrators, said the investigators. And, they say, journals and institutions haven’t devoted enough resources to prevent or investigate misconduct.

“A lot of editors did not even want to investigate because they just didn’t want to believe that there could be fraud in science,” said Dr. Bik of her experiences. “I hope that by now most journals at least should have realized that some proportion of the manuscripts that get sent to their journals is going to be fraud,” she said.

“The bulk of the journals seem like they don’t want to be bothered by this,” agreed Dr. Schrag, adding that “some have gone to great lengths to try to discourage people from bringing forward complaints.”

A big issue is that journals “don’t answer to any higher authority,” said Dr. Schrag. He believes that journals that repeatedly refuse to address integrity issues should be barred from publishing research produced with funds from the National Institutes of Health.

All the investigators said institutions and journals should hire forensic investigators. Relying on unpaid peer reviewers or editors to root out fraud is unrealistic, they said.

“You want to have specialized people with experience and be paid to do that as a full-time job,” said Dr. Bik, who is funded by speaking engagements and receives about $2300 a month through donations to her Patreon account.

Once a potential integrity issue is flagged, there is “an incredible conflict of interest in how these investigations are run,” said Dr. Schrag. “Institutions are asked to investigate their own faculty; they’re asked to investigate themselves.” That “creates the disincentive to move expeditiously,” said Dr. Schrag.

With the space of time, people who have committed fraud can throw out notebooks, delete data from servers, or even PhotoShop original photos so they match the manipulated ones that were submitted, Dr. Bik said.

Institutions could show they are serious about fraud by offering a “central, systematic universal screening of all image data going out of their institutions before submission to a journal,” said Dr. Rossner. But he knows only of a handful that do so. “I think research integrity offices have historically been very reactive, and they need to pivot and become proactive,” said Dr. Rossner.

Dr. Schrag wants to see stronger values within the research enterprise. “You have to build a culture where it’s absolutely anathema at a core level to violate these standards of research integrity,” he said. “We have this notion that we can push the process along faster and get to a grant and get to a paper and get to some short-term goal,” he said. “But the long-term goal in most of these cases is to cure a disease or to understand some biological mysteries. There’s no shortcut to getting there,” said Dr. Schrag.

There have been some high-profile consequences for research integrity failures, such as the 2023 resignation of Stanford University President Marc Tessier-Lavigne in the wake of findings that members of his lab — but not Tessier-Lavigne — engaged in data manipulation.

The process is often opaque, with investigations done in secrecy. “Consequences are not usually revealed, either,” said Dr. Rossner.

Dr. Schrag acknowledges it’s a tough balancing act for institutions to root out bad actors while also ensuring there’s no harm to those who may simply have operated in error.

“But it doesn’t serve anyone’s interest including the people who are accused, in dragging these things out for 5, 6, 8, or 10 years,” he said.

Lesne and Cassava: The Long and Winding Road

The investigations into the Lesne papers and the work underpinning Cassava Sciences’ therapy point to the difficulty of policing integrity and the potential fallout.

Lesne’s signature paper published in Nature in 2006 has been cited some 2300 times and is the fourth most-accessed article of 81,612 articles of a similar age in all journals tracked by Altimetrics.

Dr. Schrag, Dr. Bik, and others wrote to multiple journals asking them to investigate some 25 papers related to simufilam, including a 2012 Journal of Clinical Investigation article by Hoau-Yan Wang, PhD, the CUNY scientist whose work on simufilam has been questioned.

JCI Editor Elizabeth McNally pushed back stating in an editorial in 2022 that they, as whistleblowers, had potential conflicts and that they could be assisting short sellers who were seeking to profit by depressing Cassava’s stock price. Indeed, Dr. Schrag was initially hired by a law firm that was representing short sellers. Ms. McNally said that JCI would start requiring disclosures by whistleblowers.

Dr. Bik urged CUNY to investigate Dr. Wang in 2021 but was rebuffed. Then, in November 2023, a copy of CUNY’s final report on the Wang inquiry was leaked to Science. The university reported that Dr. Wang did not provide any original data or notebooks and that it found “long-standing and egregious misconduct in data management and record keeping by Dr. Wang,” wrote Dr. Bik in a blog post summarizing the investigation.

As of late 2023, 42 papers by Dr. Wang have earned PubPeer posts, seven have been retracted, and five have been marked with an Expression of Concern, wrote Dr. Bik.

Some have called for Cassava to stop its phase 3 studies of simufilam, but the company is proceeding, announcing in November 2023 that they have completed enrollment.

Misconduct Queries Underway at USC and Temple

Meanwhile, Dr. Schrag and Dr. Bik continue sleuthing. They are among a small group of whistleblowers who have filed a complaint with NIH about irregularities in the Zlokovic lab at USC. They allege that images were manipulated in dozens of papers, including some that inform the development of a stroke drug in phase 2 trials.

The inquiry goes well beyond stroke, said Dr. Schrag. Dr. Zlokovic “is one of the most influential scientists on Alzheimer’s scientists in the country,” Dr. Schrag said. The USC scientist is a leader on blood-brain barrier research.

USC is investigating “at some level,” he said. In a statement to this news organization, USC said that it “takes any allegations about research integrity very seriously.” The statement added, “Consistent with federal regulations and USC policies, this review must be kept confidential. As a result, we are unable to provide any further information.”

Mu Yang, PhD, assistant professor of neurobiology at Columbia University Medical Center in New York City, is also working on the Zlokovic investigation.

She calls herself an “accidental sleuth” who fell into the hobby after a graduate student asked her to help replicate a study by Temple University, Philadelphia, Pennsylvania, researcher Dominco Pratico, MD, of Alzheimer’s-like phenotype mice in the Morris Water Maze test. Dr. Yang, who runs the “behavior core” at Columbia — teaching and advising on how to run assays and collect and report data — could see right away that the Pratico data were “too perfect.”

She enlisted maze inventor Richard Morris to join her in a letter of concern to the journals that published Dr. Pratico’s work, all under the aegis of Springer Nature.

The publisher’s integrity team has since retracted four Pratico papers. Three were because of image abnormalities pointed out by Dr. Bik, who worked with Dr. Yang. One was because of “self-plagiarism.”

“The official retraction notes didn’t mention anything about data abnormality being a concern,” said Dr. Yang who says that questionable data is harder to prove than an image duplication or manipulation. And the papers remain available, although dozens of Practico papers have been flagged on PubPeer.

To Dr. Yang, images are the canary in the coalmine. “People don’t just fake western blots but then give real behavior data or give you fake behavior data but give you the most authentic Western Blots,” she said.

Dr. Pratico has now sued a graduate student who was a coauthor on the papers, according to the Philadelphia Inquirer.

The NIH’s ORI has requested that Temple University conduct an investigation, Dr. Yang said.

In a statement to this news organization, Temple said it “does not comment on internal investigations or personnel issues,” but that “allegations of research misconduct are reviewed and investigated centrally through Temple’s Office of the Vice President for Research in accordance with university policy and applicable federal regulations.”

Alzheimer’s research is plagued with misconduct and fraud, undermining the progress toward understanding and treating the disease, say investigators who endeavor to expose errors and misleading practices.

The book is yet to be closed, for instance, on whether a 2006 paper by Sylvain Lesne positing amyloid as a major cause of Alzheimer’s was based on fraudulent data. Suspicions about the paper were first raised in late 2021 by Matthew Schrag, MD, PhD, an assistant professor of neurology at Vanderbilt University Medical Center, Nashville, Tennessee.

Dr. Schrag also queried the work of a City University of New York (CUNY) researcher who proposed PT-125 (now simufilam) as a potential anti-amyloid for Alzheimer’s disease. Even though CUNY recently found “egregious” and potentially deliberate misconduct by that researcher, Cassava Sciences is continuing phase 3 trials of simufilam.

Now questions are being raised about work from the lab of Berislav V. Zlokovic, PhD, a prominent neuroscientist at the University of Southern California (USC), Los Angeles, California, and also about studies conducted under the aegis of Domenico Pratico, MD, the director of the Alzheimer’s Center at Temple University in Philadelphia, Pennsylvania.

Alzheimer’s has been a notoriously hard puzzle to solve. Despite decades of research, there are still no effective therapies and disparate theories about potential causes.

Dr. Schrag said he wouldn’t “attribute all the ills in this field” to misconduct, but it “is absolutely a part of the equation.” Some of the papers flagged for integrity issues “have been hugely influential,” he said in an interview. “Some of the labs that we’re talking about have really shaped how we’ve thought about this disease,” he said. “It’s hard to un-ring the bell.”

The fallout from fraud has a wide impact. Taxpayer dollars are wasted in the creation of the fraud and in attempts to replicate the failed experiment. Grad students — the workhorses of labs — waste time trying to repeat studies or may be bullied or intimidated into misconduct, said Elisabeth Bik, PhD, a former Stanford microbiologist who is now a full-time fraud investigator.

And there’s potential harm to patients. “There’s a lot of false hope being given to these people and their families,” Dr. Bik said in an interview.
 

Alzheimer’s Tempts With Big Rewards

There are big rewards for those who publish important papers on Alzheimer’s: More grants, publication in higher-impact journals, larger labs, and potentially, personal enrichment from commercialization of therapies.

“I can see that people are driven to cut corners or even to make up results, or even anything in between, to reach that goal,” said Dr. Bik.

It’s unclear whether misconduct and fraud are on the rise or just being detected more frequently.

“It’s very hard to say,” said Mike Rossner, PhD, president of Image Data Integrity. Institutions hire Dr. Rossner to help ferret out research integrity issues. He told this news organization that it’s likely detection is on the rise, given the increasing number of sleuths like Dr. Bik.

In 2002, Dr. Rossner began to screen all images submitted to the Journal of Clinical Biology in response to the new phenomenon of digital images and the advent of PhotoShop. “Very early on, we started to see problems in digital images that we would not have seen on a glossy printout,” Dr. Rossner said of his time as managing editor of the journal.

From 2002 to 2014, at least 25% of papers had an image that violated guidelines that prohibited the removal of spots or other blemishes (called “beautification”) with PhotoShop, which did not necessarily indicate fraud. They withdrew acceptance for 1% of papers because of image manipulations that affected data interpretation.

Dr. Bik noted that even if there is not a greater percentage of fraudulent papers in Alzheimer’s, “it would still be in absolute numbers a lot of papers that could be fraudulent,” given that Alzheimer’s research is well-funded with federal agencies alone providing $3.7 billion a year.

Images Key to Spotting Issues

Investigative sleuths often use the online forum PubPeer to initially raise questions about papers. The format gives the original authors a chance to comment on or defend their work. While some critiques are about data, most hone in on alleged duplications or manipulations of images, primarily by Western Blots.

The images are key, because “the images are the data,” said Dr. Rossner. “The words are the author’s interpretation of what they see in the images,” he said.

It’s also easier to spot a problem in an image. The raw data or an investigator’s notebooks aren’t needed, and there are artificial intelligence-driven software programs such as Proofig and Image Twin that help investigators spot duplicated images or cases in which an image might have been flipped or otherwise manipulated to make results look better.

Science recently announced that it would be using Proofig to screen images in all papers submitted to its six journals.

Using a screening tool is better than nothing, said Dr. Rossner who still relies on visual inspection, employing contrast or other features in PhotoShop to spot inconsistencies or duplications. But “none of those companies have disclosed how effective they are relative to visual screening, and that to me is very problematic,” he said.

“The tools are not going to catch everything,” said Dr. Bik.

Dr. Schrag agreed. “One of the things that we’re worried about is that a lot of the journals will simply adopt these tools as a screener and assume that that’s going to de-risk their publication portfolio,” he said, noting the high rate of misses.

TOPLINE:

The remission period of type 1 diabetes (T1D) can be prolonged with high-dose ergocalciferol (a vitamin D analog), by preserving the function of insulin-producing beta cells in newly diagnosed patients.

METHODOLOGY:

• Beta cells may retain approximately 30%-50% function at the time of T1D diagnosis and continue producing insulin for months or years. Preserving beta-cell function early on can extend this remission period and improve long-term glycemic control.
• Researchers conducted a secondary post hoc analysis of a randomized clinical trial looking at residual beta function and vitamin D supplementation in 36 youths (age, 10-21 years; mean age, 13.5 years; 33.3% women) with recently diagnosed T1D.
• Participants were randomly assigned to receive vitamin D (50,000 international units) or placebo every week for 2 months and then biweekly for 10 months.
• Mixed-meal tolerance tests were performed after overnight fasting at 0, 3, 6, 9, and 12 months, and blood draws were obtained 30 minutes and 90 minutes for post-meal C-peptide and glucose estimations.
• The fasting proinsulin to C-peptide ratio (PI:C) and the percentage change in the area under the curve of C-peptide from baseline (%ΔAUC) were calculated to test the effect of vitamin D on beta-cell function.

TAKEAWAY: 

• Vitamin D supplementation improved the insulin secretion capacity of beta cells, as observed by the decrease in the mean fasting PI:C ratio compared with placebo (−0.0009 vs 0.0011; P =.01).
• The reduction in %ΔAUC of C-peptide was notably slower with vitamin D than placebo (−2.8% vs −4.7%; P =.03), indicating a longer delay in the loss of C-peptide.

IN PRACTICE:

“It is exciting to know that vitamin D could protect the beta cells of the pancreas and increase the natural production of good and functional insulin in these patients. This, in turn, prolongs the honeymoon phase of type 1 diabetes and leads to reduced long-term complications of this disease,” Benjamin Udoka Nwosu, MD, Northwell Health, Division of Endocrinology, Department of Pediatrics, Cohen Children’s Medical Center, New Hyde Park, New York, the principal author, said in a press release.

SOURCE:

The study was published online in JAMA Network Open.

LIMITATIONS:

It was a single-center study.

DISCLOSURES:

The study was supported by the National Institute of Diabetes and Digestive and Kidney Diseases. The authors did not report any conflicts of interest.

Working with medically trained service dogs is associated with a 31% reduction in seizures compared with usual care in treatment-resistant epilepsy, a new study showed.

Investigators speculate that the dogs may ease participants’ stress, leading to a decrease in seizure frequency, although they note this relationship warrants more study.

“Despite the development of numerous antiseizure medications over the past 15 years, up to 30% of people with epilepsy experience persistent seizures,” study author Valérie van Hezik-Wester, MSc, of Erasmus University Rotterdam, Rotterdam, the Netherlands, said in a press release.

The unpredictable nature of seizures is one of the most disabling aspects of epilepsy, Ms. Hezik-Wester added. Seizure dogs are trained to recognize seizures and respond when they occur.

“The tasks that these dogs perform, along with their companionship, may reduce seizure-related anxiety, also potentially reducing seizures caused by stress, the most common trigger for seizures,” she said.

The study included 25 individuals with medically refractory epilepsy who had an average of two or more seizures per week, with seizure characteristics associated with a high risk for injuries or dysfunction. They also had to be able to care for a service dog.

All were observed under usual care, which included antiseizure medications, neurostimulation devices, and other supportive therapies. Participants could then choose to work with a service dog that had completed socialization and obedience training or be assigned a puppy they would train at home.

The median follow-up was 19 months with usual care and 12 months with the intervention. Participants recorded seizure activity in diaries and completed surveys on seizure severity, quality of life, and well-being every 3 months. Daily seizure counts were converted to obtain cumulative seizure frequencies over 28-day periods.

Of the 25 original participants, six discontinued trial participation before the end of follow-up, four of whom left the study due to difficulty with dog care and training.

Participants receiving usual care reported an average of 115 seizures per 28-day period, while those with trained service dogs recorded 73 seizures in the same period, or a 37% difference between groups.

Researchers found that participants had an average of 31% fewer seizures during the past 3 months when they had seizure dogs, with seven participants achieving a 50%-100% reduction in seizures.

The number of seizure-free days increased from an average of 11 days per 28-day period before receiving a service dog to 15 days after working with a dog.

Scores on the EQ-5D-5L, which measures perceived health problems, decreased on average by 2.5% per consecutive 28-day period with the intervention, reflecting an increase in generic health-related quality of life (0.975; 95% CI, 0.954-0.997).

“These findings show that seizure dogs can help people with epilepsy,” said Ms. van Hezik-Wester. “However, we also found that this partnership with seizure dogs might not be the right fit for everyone, as some people discontinued their participation in this program. More research is needed to better understand which people can benefit from working with seizure dogs.”
 

Enhanced Quality of Life

In an accompanying editorial, Amir Mbonde, MB, and Amy Crepeau, MD, of Mayo Clinic in Phoenix, Arizona, noted the findings add to a growing body of work on the effectiveness of service dogs in reducing seizure frequency.

“In addition to improved seizure control, the EPISODE study demonstrated the benefit of seizure dogs in enhancing the quality of life for patients, a crucial component of comprehensive epilepsy care,” they wrote.

In prior studies, seizure dogs have identified an odor that a person emits before a seizure in up to 97% of people, they noted, adding that this ability “offers immense clinical benefits to people with epilepsy, enhancing their independence, social engagement, employment opportunities, self-confidence, and thus quality of life.”

Study limitations include its small sample size and high attrition rate.

The study was funded by the Netherlands Organization for Health Research and Development and Innovatiefonds Zorgverzekeraars.

Working with medically trained service dogs is associated with a 31% reduction in seizures compared with usual care in treatment-resistant epilepsy, a new study showed.

Investigators speculate that the dogs may ease participants’ stress, leading to a decrease in seizure frequency, although they note this relationship warrants more study.

“Despite the development of numerous antiseizure medications over the past 15 years, up to 30% of people with epilepsy experience persistent seizures,” study author Valérie van Hezik-Wester, MSc, of Erasmus University Rotterdam, Rotterdam, the Netherlands, said in a press release.

The unpredictable nature of seizures is one of the most disabling aspects of epilepsy, Ms. Hezik-Wester added. Seizure dogs are trained to recognize seizures and respond when they occur.

“The tasks that these dogs perform, along with their companionship, may reduce seizure-related anxiety, also potentially reducing seizures caused by stress, the most common trigger for seizures,” she said.

The findings were published online in Neurology.
