New Biological Pathway May Explain BPA Exposure, Autism Link

Article Type
Changed
Tue, 08/13/2024 - 15:15

Higher prenatal exposure to the chemical bisphenol A (BPA) is associated with a greater risk for autism spectrum disorder (ASD) in men, potentially via the disruption of a key enzyme in the developing brain.

BPA is a potent endocrine disruptor found in polycarbonate plastics and epoxy resins and has been banned by the Food and Drug Administration for use in baby bottles, sippy cups, and infant formula packaging.

“Exposure to BPA has already been shown in some studies to be associated with subsequent autism in offspring,” lead researcher Anne-Louise Ponsonby, PhD, The Florey Institute, Heidelberg, Australia, said in a statement.

“Our work is important because it demonstrates one of the biological mechanisms potentially involved. BPA can disrupt hormone-controlled male fetal brain development in several ways, including silencing a key enzyme, aromatase, that controls neurohormones and is especially important in fetal male brain development. This appears to be part of the autism puzzle,” she said.

Brain aromatase, encoded by CYP19A1, converts neural androgens to neural estrogens and has been implicated in ASD. Postmortem analyses of men with ASD also show markedly reduced aromatase activity.

The findings were published online in Nature Communications.
 

New Biological Mechanism

For the study, the researchers analyzed data from the Barwon Infant Study in 1067 infants in Australia. At age 7-11 years, 43 children had a confirmed ASD diagnosis, and 249 infants with Child Behavior Checklist (CBCL) data at age 2 years had an autism spectrum problem score above the median.

The researchers developed a CYP19A1 genetic score for aromatase activity based on five single nucleotide polymorphisms associated with lower estrogen levels. Among 595 children with prenatal BPA and CBCL, those with three or more variants were classified as “low aromatase activity” and the remaining were classified as “high.”

In regression analyses, boys with low aromatase activity and high prenatal BPA exposure (top quartile > 2.18 µg/L) were 3.5 times more likely to have autism symptoms at age 2 years (odds ratio [OR], 3.56; 95% CI, 1.13-11.22).

The odds of a confirmed ASD diagnosis were six times higher at age 9 years only in men with low aromatase activity (OR, 6.24; 95% CI, 1.02-38.26).

The researchers also found that higher BPA levels predicted higher methylation in cord blood across the CYP19A1 brain promoter PI.f region (P = .009).

To replicate the findings, data were used from the Columbia Centre for Children’s Health Study–Mothers and Newborns cohort in the United States. Once again, the BPA level was associated with hypermethylation of the aromatase brain promoter PI.f (P = .0089).

In both cohorts, there was evidence that the effect of increased BPA on brain-derived neurotrophic factor hypermethylation was mediated partly through higher aromatase gene methylation (P = .001). 

To validate the findings, the researchers examined human neuroblastoma SH-SY5Y cell lines and found aromatase protein levels were more than halved in the presence of BPA 50 µg/L (P = .01).

Additionally, mouse studies showed that male mice exposed to BPA 50 µg/L mid-gestation and male aromatase knockout mice — but not female mice — had social behavior deficits, such as interacting with a strange mouse, as well as structural and functional brain changes.

“We found that BPA suppresses the aromatase enzyme and is associated with anatomical, neurologic, and behavioral changes in the male mice that may be consistent with autism spectrum disorder,” Wah Chin Boon, PhD, co–lead researcher and research fellow, also with The Florey Institute, said in a statement.

“This is the first time a biological pathway has been identified that might help explain the connection between autism and BPA,” she said.

“In this study, not only were the levels of BPA higher than most people would be exposed to, but in at least one of the experiments the mice were injected with BPA directly, whereas humans would be exposed via food and drink,” observed Oliver Jones, PhD, MSc, professor of chemistry, RMIT University, Melbourne, Australia. “If you ingest the food, it undergoes metabolism before it gets to the bloodstream, which reduces the effective dose.”

Dr. Jones said further studies with larger numbers of participants measuring BPA throughout pregnancy and other chemicals the mother and child were exposed to are needed to be sure of any such link. “Just because there is a possible mechanism in place does not automatically mean that it is activated,” he said.

Dr. Ponsonby pointed out that BPA and other endocrine-disrupting chemicals are “almost impossible for individuals to avoid” and can enter the body through plastic food and drink packaging, home renovation fumes, and sources such as cosmetics.
 

 

 

Fatty Acid Helpful? 

Building on earlier observations that 10-hydroxy-2-decenoic acid (10HDA) may have estrogenic modulating activities, the researchers conducted additional studies suggesting that 10HDA may be effective as a competitive ligand that could counteract the effects of BPA on estrogen signaling within cells.

Further, among 3-week-old mice pups prenatally exposed to BPA, daily injections of 10HDA for 3 weeks showed striking and significant improvements in social interaction. Stopping 10HDA resulted in a deficit in social interaction that was again ameliorated by subsequent 10HDA treatment.

“10-hydroxy-2-decenoic acid shows early indications of potential in activating opposing biological pathways to improve autism-like characteristics when administered to animals that have been prenatally exposed to BPA,” Dr. Boon said. “It warrants further studies to see whether this potential treatment could be realized in humans.”

Reached for comment, Dr. Jones said “the human studies are not strong at all,” in large part because BPA levels were tested only once at 36 weeks in the BIS cohort.

“I would argue that if BPA is in the urine, it has been excreted and is no longer in the bloodstream, thus not able to affect the child,” he said. “I’d also argue that a single measurement at 36 weeks cannot give you any idea of the mother’s exposure to BPA over the rest of the pregnancy or what the child was exposed to after birth.”

The study was funded by the Minderoo Foundation, the National Health and Medical Research Council of Australia, the Australian Research Council, and numerous other sponsors. Dr. Boon is a coinventor on “Methods of treating neurodevelopmental diseases and disorders” and is a board member of Meizon Innovation Holdings. Dr. Ponsonby is a scientific adviser to Meizon Innovation Holdings. The remaining authors declared no competing interests.

Sexual Arousal Cream Promising in Some Subsets of Women

Article Type
Changed
Tue, 08/13/2024 - 10:09

Topical sildenafil (citrate) cream 3.6% used by healthy premenopausal women with a primary symptom of female sexual arousal disorder did not show statistically significant improvement over placebo in the coprimary or secondary endpoints over a 3-month period in new preliminary study data published in Obstetrics & Gynecology.

Topical sildenafil cream is currently used for erectile dysfunction in men. There are no US Food and Drug Administration–approved treatments for female sexual arousal disorder, which affects up to 26% of women in the United States by some estimates.

Isabella Johnson, senior manager of product development at Daré Bioscience, San Diego, California, led a phase 2b, exploratory, randomized, placebo-controlled, double-blind study of sildenafil cream’s potential to help women improve their sexual experiences.

The study included 200 women with female sexual arousal disorder randomized to sildenafil cream (n = 101) or placebo cream (n = 99); 177 completed the trial and made up the intention-to-treat group. Healthy premenopausal women at least 18 years old and their sexual partners were screened for the study.

The authors report that the primary endpoints were scores on Sexual Function Questionnaire (SFQ28) arousal sensation domain and question 14 on the Female Sexual Distress Scale — Desire/Arousal/Orgasm (FSD-DAO), which asks “How often in the past 30 days did you feel concerned by difficulties with sexual arousal?”  The secondary endpoint was the average number and average proportion of satisfactory sexual events. Topical sildenafil was not more effective than placebo with these primary or secondary endpoints.
 

Some Subgroups Benefited

However, a post hoc analysis told a different story. “[A]mong a subset of women with female sexual arousal disorder only or female sexual arousal disorder with concomitant decreased desire, we found either trends or significant improvements in sexual functioning with sildenafil cream compared with placebo cream across multiple aspects of sexual function,” the authors write.

The researchers also noted that several FSDS-DAO questions, other than question 14, asked about generalized feelings related to sexual distress and interpersonal difficulties and scores on those questions showed significant improvement with sildenafil cream compared with placebo in the exploratory subset.

“The total FSDS-DAO score decreased by about 7 points for sildenafil cream users in the subset population (a clinically meaningful decrease in sexual distress) compared with a two-point decrease for placebo cream users (P = .10),” they write.

Post Hoc Analysis Is Exploratory

JoAnn V. Pinkerton, MD, with the Department of Obstetrics and Gynecology, University of Virginia Health in Charlottesville, writes in an editorial that because the authors did not adjust for multiple hypothesis testing, the post hoc subset analyses should be considered only exploratory.

She notes that the trial was underpowered partly because it was halted after recruitment challenges during the COVID-19 pandemic. The small sample size and the varied reasons for arousal disorder among the women “may have limited the ability to find a positive outcome.”

The underlying mechanisms of female sexual arousal disorder are not well understood. But the study findings point to some groups that may benefit or likely will not benefit, Dr. Pinkerton writes.

“Because improvement in genital arousal is thought to be due to the increased genital blood flow from sildenafil citrate, the subset of participants found least likely to benefit from sildenafil citrate cream were those with concomitant orgasmic dysfunction with or without genital pain,” she writes.
 

 

 

Data May Inform Phase 3 Trial

This phase 2b trial sets the stage for a phase 3 trial, she writes, to evaluate sildenafil topical cream in women with female sexual arousal disorder in the subsets where there were positive findings (those with or without a secondary diagnosis of decreased desire) but not among women having difficulty reaching orgasm.

“If positive, it could lead to a new therapeutic area for the unmet treatment needs of premenopausal and postmenopausal women with female sexual arousal disorder,” Dr. Pinkerton writes.

Navigating Election Anxiety: How Worry Affects the Brain

Article Type
Changed
Tue, 08/13/2024 - 04:13

Once again, America is deeply divided before a national election, with people on each side convinced of the horrors that will be visited upon us if the other side wins. 

’Tis the season — and regrettably, not to be jolly but to be worried.

As a neuroscientist, I am especially aware of the deleterious mental and physical impact of chronic worry on our citizenry. That’s because worry is not “all in your head.” Chronic mild stress drives a panoply of negative changes in your body and brain that add to your risk for physical and neurologic troubles. We modern humans live in a world of worry which appears to be progressively growing.
 

Flight or Fight

Worry stems from the brain’s rather remarkable ability to foresee and reflexively respond to threat. Our “fight or flight” brain machinery probably arose in our vertebrate ancestors more than 300 million years ago. The fact that we have machinery akin to that possessed by lizards or tigers or shrews is testimony to its crucial contribution to our species’ survival.

As the phrase “fight or flight” suggests, a brain that senses trouble immediately biases certain body and brain functions. As it shifts into a higher-alert mode, it increases the energy supplies in our blood and supports other changes that facilitate faster and stronger reactions, while it shuts down less essential processes which do not contribute to hiding, fighting, or running like hell.

This hyperreactive response is initiated in the amygdala in the anterior brain, which identifies “what’s happening” as immediately or potentially threatening. The now-activated amygdala generates a response in the hypothalamus that provokes an immediate increase of adrenaline and cortisol in the body, and cortisol and noradrenaline in the brain. Both sharply speed up our physical and neurologic reactivity. In the brain, that is achieved by increasing the level of excitability of neurons across the forebrain. Depending on the perceived level of threat, an excitable brain will be just a little or a lot more “on alert,” just a little or a lot faster to respond, and just a little or a lot better at remembering the specific “warning” events that trigger this lizard-brain response. 

Alas, this machinery was designed to be engaged every so often when a potentially dangerous surprise arises in life. When the worry and stress are persistent, the brain experiences a kind of neurologic “burn-out” of its fight versus flight machinery.
 

Dangers of Nonstop Anxiety and Stress

A consistently stressed-out brain turns down its production and release of noradrenaline, and the brain becomes less attentive, less engaged. This sets the brain on the path to an anxiety (and then a depressive) disorder, and, in the longer term, to cognitive losses in memory and executive control systems, and to emotional distortions that can lead to substance abuse or other addictions.

Our political distress is but one source of persistent worry and stress. Worry is a modern plague. The head counts of individuals seeking psychiatric or psychological health are at an all-time high in the United States. Near-universal low-level stressors, such as 2 years of COVID, insecurities about the changing demands of our professional and private lives, and a deeply divided body politic are unequivocally affecting American brain health.

The brain also collaborates in our body’s response to stress. Its regulation of hormonal responses and its autonomic nervous system’s mediated responses contribute to elevated blood sugar levels, to craving high-sugar foods, to elevated blood pressure, and to weaker immune responses. This all contributes to higher risks for cardiovascular and other dietary- and immune system–related disease. And ultimately, to shorter lifespans.
 

 

 

Strategies to Address Neurologic Changes Arising From Chronic Stress

There are many things you can try to bring your worry back to a manageable (and even productive) level.

  • Engage in a “reset” strategy several times a day to bring your amygdala and locus coeruleus back under control. It takes a minute (or five) of calm, positive meditation to take your brain to a happy, optimistic place. Or use a mindfulness exercise to quiet down that overactive amygdala.
  • Talk to people. Keeping your worries to yourself can compound them. Hashing through your concerns with a family member, friend, professional coach, or therapist can help put them in perspective and may allow you to come up with strategies to identify and neurologically respond to your sources of stress.
  • Exercise, both physically and mentally. Do what works for you, whether it’s a run, a long walk, pumping iron, playing racquetball — anything that promotes physical release. Exercise your brain too. Engage in a project or activity that is mentally demanding. Personally, I like to garden and do online brain exercises. There’s nothing quite like yanking out weeds or hitting a new personal best at a cognitive exercise for me to notch a sense of accomplishment to counterbalance the unresolved issues driving my worry.
  • Accept the uncertainty. Life is full of uncertainty. To paraphrase from Yale theologian Reinhold Niebuhr’s “Serenity Prayer”: Have the serenity to accept what you cannot help, the courage to change what you can, and the wisdom to recognize one from the other.

And, please, be assured that you’ll make it through this election season.

Dr. Merzenich, professor emeritus, Department of Neuroscience, University of California San Francisco, disclosed ties with Posit Science. He is often credited with discovering lifelong plasticity, with being the first to harness plasticity for human benefit (in his co-invention of the cochlear implant), and for pioneering the field of plasticity-based computerized brain exercise. He is a Kavli Laureate in Neuroscience, and he has been honored by each of the US National Academies of Sciences, Engineering, and Medicine. He may be most widely known for a series of specials on the brain on public television. His current focus is  BrainHQ, a brain exercise app.

More Access to Perinatal Mental Healthcare Needed

Article Type
Changed
Fri, 08/09/2024 - 15:15

Despite federal legislation improving healthcare access, concerted efforts are still needed to increase evidence-based treatment for maternal perinatal mental health issues, a large study of commercially insured mothers suggested. It found that federal legislation had variable and suboptimal effect on mental health services use by delivering mothers.

In the cross-sectional study, published in JAMA Network Open, psychotherapy receipt increased somewhat during 2007-2019 among all mothers and among those diagnosed with perinatal mood and anxiety disorders (PMADs). The timeline encompassed periods before and after passage of the Mental Health Parity and Addiction Equity Act (MHPAEA) of 2008 and the Patient Protection and Affordable Care Act (ACA) of 2010.

The investigators, led by Kara Zivin, PhD, MS, MFA, a professor of psychiatry in the University of Michigan’s School of Public Health at Ann Arbor, found the results varied by policy and between the overall delivering population and the PMAD population. “We did not find a statistically significant immediate change associated with the MHPAEA or ACA in the overall delivering population, except for a steady increase in delivering women who received any psychotherapy after ACA,” Dr. Zivin and colleagues wrote.

The researchers looked at private insurance data for 837,316 deliveries among 716,052 women (64.2% White), ages 15-44 (mean 31.2), to assess changes in psychotherapy visits in the year before and after delivery. They also estimated per-visit out-of-pocket costs for the ACA in 2014 and the MHPAEA in 2010.

In the PMAD population, the MHPAEA was associated with an immediate increase in psychotherapy receipt of 0.72% (95% CI, 0.26%-1.18%; P = .002), followed by a sustained decrease of 0.05% (95% CI, 0.09%-0.02%; P = .001).

In both populations, the ACA was associated with immediate and sustained monthly increases in use of 0.77% (95% CI, 0.26%-1.27%; P = .003) and 0.07% (95% CI, 0.02%-0.12%; P = .005), respectively.

Post MHPAEA, both populations experienced a slight decrease in per-visit monthly out-of-pocket costs, while after the ACA they saw an immediate and steady monthly increase in these.

Although both policies expanded access to any psychotherapy, the greater number of people receiving visits coincided with fewer visits per person, the authors noted. “One hypothesis suggests that the number of available mental health clinicians may not have increased enough to meet the new demand; future research should better characterize this trend,” they wrote.

In addition, a lower standard cost per visit may have dampened the incentive to increase the number of mental health clinicians, they conjectured. These factors could explain why the PMAD group appeared to experience a decrease in the proportion receiving any psychotherapy after the MHPAEA’s implementation.

The findings should be reviewed in the context of the current mental health burden, the authors wrote, in which the shortage of mental health professionals means that less than 30% of mental healthcare needs are being met.

They called for more measures to mitigate the excess burden of PMADs.

This study was funded by the National Institutes of Health. Dr. Zivin had no conflicts of interest. Coauthor Dr. Dalton reported personal fees from Merck, the Society of Family Planning, Up to Date, and The Medical Letter outside of the submitted work.

Despite federal legislation improving healthcare access, concerted efforts are still needed to increase evidence-based treatment for maternal perinatal mental health issues, a large study of commercially insured mothers suggested. It found that federal legislation had variable and suboptimal effect on mental health services use by delivering mothers.

In the cross-sectional study, published in JAMA Network Open, psychotherapy receipt increased somewhat during 2007-2019 among all mothers and among those diagnosed with perinatal mood and anxiety disorders (PMADs). The timeline encompassed periods before and after passage of the Mental Health Parity and Addiction Equity Act (MHPAEA) of 2008 and the Patient Protection and Affordable Care Act (ACA) of 2010.

The investigators, led by Kara Zivin, PhD, MS, MFA, a professor of psychiatry in the University of Michigan’s School of Public Health at Ann Arbor, found the results varied by policy and between the overall delivering population and the PMAD population. “We did not find a statistically significant immediate change associated with the MHPAEA or ACA in the overall delivering population, except for a steady increase in delivering women who received any psychotherapy after ACA,” Dr. Zivin and colleagues wrote.

The researchers looked at private insurance data for 837,316 deliveries among 716,052 women (64.2% White), ages 15-44 (mean 31.2), to assess changes in psychotherapy visits in the year before and after delivery. They also estimated per-visit out-of-pocket costs for the ACA in 2014 and the MHPAEA in 2010.

In the PMAD population, the MHPAEA was associated with an immediate increase in psychotherapy receipt of 0.72% (95% CI, 0.26%-1.18%; P = .002), followed by a sustained decrease of 0.05% (95% CI, 0.09%-0.02%; P = .001).

In both populations, the ACA was associated with immediate and sustained monthly increases in use of 0.77% (95% CI, 0.26%-1.27%; P = .003) and 0.07% (95% CI, 0.02%-0.12%; P = .005), respectively.

Post MHPAEA, both populations experienced a slight decrease in per-visit monthly out-of-pocket costs, while after the ACA they saw an immediate and steady monthly increase in these.

Although both policies expanded access to any psychotherapy, the greater number of people receiving visits coincided with fewer visits per person, the authors noted. “One hypothesis suggests that the number of available mental health clinicians may not have increased enough to meet the new demand; future research should better characterize this trend,” they wrote.

In addition, a lower standard cost per visit may have dampened the incentive to increase the number of mental health clinicians, they conjectured. These factors could explain why the PMAD group appeared to experience a decrease in the proportion receiving any psychotherapy after the MHPAEA’s implementation.

The findings should be reviewed in the context of the current mental health burden, the authors wrote, in which the shortage of mental health professionals means that less than 30% of mental healthcare needs are being met.

They called for more measures to mitigate the excess burden of PMADs.

This study was funded by the National Institutes of Health. Dr. Zivin had no conflicts of interest. Coauthor Dr. Dalton reported personal fees from Merck, the Society of Family Planning, Up to Date, and The Medical Letter outside of the submitted work.

How Clinicians Can Help Patients Navigate Psychedelics/Microdosing

Article Type
Changed
Thu, 08/08/2024 - 11:55

Peter Grinspoon, MD, has some advice for clinicians when patients ask questions about microdosing of psychedelics: Keep the lines of communication open — and don’t be judgmental.

“If you’re dismissive or critical or sound like you’re judging them, then the patients just clam up,” said Dr. Grinspoon, a professor of medicine at Harvard Medical School and a primary care physician at Massachusetts General Hospital, both in Boston.

Psychedelic drugs are still illegal in the majority of states despite the growth of public interest in and use of these substances. That growth is evidenced by a flurry of workshops, reportslaw enforcement seizures, and pressure by Congressional members for the Food and Drug Administration to approve new psychedelic drugs, just in the past year.

A recent study in JAMA Health Forum showed a nearly 14-fold increase in Google searches — from 7.9 to 105.6 per 10 million nationwide — for the term “microdosing” and related wording, between 2015 and 2023.

Two states — Oregon and Colorado — have decriminalized certain psychedelic drugs and are in various stages of establishing regulations and centers for prospective clients. Almost two dozen localities, like Ann Arbor, Michigan, have decriminalized psychedelic drugs. A handful of states have active legislation to decriminalize use, while others have bills that never made it out of committee.

But no definitive studies have reported that microdosing produces positive mental effects at a higher rate than placebo, according to Dr. Grinspoon. So responding to patient inquiries about microdosing can be complicated, and clinicians must provide counsel on issues of legality and therapeutic appropriateness.

“We’re in this renaissance where everybody is idealizing these medications, as opposed to 20 years ago when we were in the war on drugs and everybody was dismissing them,” Dr. Grinspoon said. “The truth is somewhere in between.”
 

The Science

Microdosing is defined as taking doses of 1/5 to 1/20 of the conventional recreational amount, which might include a dried psilocybin mushroom, lysergic acid diethylamide, or 3,4-methylenedioxymethamphetamine. But even that much may be neither effective nor safe.

Dr. Grinspoon said clinicians should tell patients that psychedelics may cause harm, although the drugs are relatively nontoxic and are not addictive. An illegally obtained psilocybin could cause negative reactions, especially if the drug has been adulterated with other substances and if the actual dose is higher than what was indicated by the seller.

He noted that people have different reactions to psychedelics, just as they have to prescription medications. He cited one example of a woman who microdosed and could not sleep for 2 weeks afterward. Only recently have randomized, double-blinded studies begun on benefits and harms.

Researchers have also begun investigating whether long-term microdosing of psilocybin could lead to valvular heart disease (VHD), said Kevin Yang, MD, a psychiatry resident at the University of California San Diego School of Medicine. A recent review of evidence concluded that microdosing various psychedelics over a period of months can lead to drug-induced VHD.

“It’s extremely important to emphasize with patients that not only do we not know if it works or not, we also don’t really know how safe it is,” Dr. Yang said.

Dr. Yang also said clinicians should consider referring patients to a mental health professional, and especially those that may have expertise in psychedelic therapies.

One of those experts is Rachel Yehuda, PhD, director of the Center for Psychedelic Psychotherapy and Trauma Research at Icahn School of Medicine at Mount Sinai in New York City. She said therapists should be able to assess the patient’s perceived need for microdosing and “invite reflections about why current approaches are falling short.”

“I would also not actively discourage it either but remain curious until both of you have a better understanding of the reasons for seeking this out and potential alternative strategies for obtaining more therapeutic benefits,” she said. “I think it is really important to study the effects of both micro- and macrodosing of psychedelics but not move in advance of the data.”
 

 

 

Navigating Legality

Recent ballot measures in Oregon and Colorado directed the states to develop regulated and licensed psilocybin-assisted therapy centers for legal “trips.” Oregon’s first center was opened in 2023, and Colorado is now developing its own licensing model.

According to the Oregon Health Authority, the centers are not medical facilities, and prescription or referral from a medical professional is not required.

The Oregon Academy of Family Physicians (OAFP) has yet to release guidance to clinicians on how to talk to their patients about these drugs or potential interest in visiting a licensed therapy center.

However, Betsy Boyd-Flynn, executive director of OAFP, said the organization is working on continuing medical education for what the average family physician needs to know if a patient asks about use.

“We suspect that many of our members have interest and want to learn more,” she said.

Dr. Grinspoon said clinicians should talk with patients about legality during these conversations.

“The big question I get is: ‘I really want to try microdosing, but how do I obtain the mushrooms?’ ” he said. “You can’t really as a physician tell them to do anything illegal. So you tell them to be safe, be careful, and to use their judgment.”

Patients who want to pursue microdosing who do not live in Oregon have two legal and safe options, Dr. Grinspoon said: Enroll in a clinical study or find a facility in a state or country — such as Oregon or Jamaica — that offers microdosing with psilocybin.

Clinicians also should warn their patients that the consequences of obtaining illicit psilocybin could exacerbate the mental health stresses they are seeking to alleviate.

“It’s going to get worse if they get tangled up with law enforcement or take something that’s contaminated and they get real sick,” he said.

Can Addressing Depression Reduce Chemo Toxicity in Older Adults?

Article Type
Changed
Wed, 08/14/2024 - 02:05

 

TOPLINE:

Elevated depression symptoms are linked to an increased risk for severe chemotherapy toxicity in older adults with cancer. This risk is mitigated by geriatric assessment (GA)-driven interventions.

METHODOLOGY:

  • Researchers conducted a secondary analysis of a randomized controlled trial to evaluate whether greater reductions in grade 3 chemotherapy-related toxicities occurred with geriatric assessment-driven interventions vs standard care.
  • A total of 605 patients aged 65 years and older with any stage of solid malignancy were included, with 402 randomized to the intervention arm and 203 to the standard-of-care arm.
  • Mental health was assessed using the Mental Health Inventory 13, and chemotherapy toxicity was graded by the National Cancer Institute Common Terminology Criteria for Adverse Events, version 4.0.
  • Patients in the intervention arm received recommendations from a multidisciplinary team based on their baseline GA, while those in the standard-of-care arm received only the baseline assessment results.
  • The study was conducted at City of Hope National Medical Center in Duarte, California, and patients were followed throughout treatment or for up to 6 months from starting chemotherapy.

TAKEAWAY:

  • According to the authors, patients with depression had increased chemotherapy toxicity in the standard-of-care arm (70.7% vs 54.3%; P = .02) but not in the GA-driven intervention arm (54.3% vs 48.5%; P = .27).
  • The association between depression and chemotherapy toxicity was also seen after adjustment for the Cancer and Aging Research Group toxicity score (odds ratio, [OR], 1.98; 95% CI, 1.07-3.65) and for demographic, disease, and treatment factors (OR, 2.00; 95% CI, 1.03-3.85).
  • No significant association was found between anxiety and chemotherapy toxicity in either the standard-of-care arm (univariate OR, 1.07; 95% CI, 0.61-1.88) or the GA-driven intervention arm (univariate OR, 1.15; 95% CI, 0.78-1.71).
  • The authors stated that depression was associated with increased odds of hematologic-only toxicities (OR, 2.50; 95% CI, 1.13-5.56) in the standard-of-care arm.
  • An analysis of a small subgroup found associations between elevated anxiety symptoms and increased risk for hematologic and nonhematologic chemotherapy toxicities.

IN PRACTICE:

“The current study showed that elevated depression symptoms are associated with increased risk of severe chemotherapy toxicities in older adults with cancer. This risk was mitigated in those in the GA intervention arm, which suggests that addressing elevated depression symptoms may lower the risk of toxicities,” the authors wrote. “Overall, elevated anxiety symptoms were not associated with risk for severe chemotherapy toxicity.”

SOURCE:

Reena V. Jayani, MD, MSCI, of Vanderbilt University Medical Center in Nashville, Tennessee, was the first and corresponding author for this paper. This study was published online August 4, 2024, in Cancer

LIMITATIONS:

The thresholds for depression and anxiety used in the Mental Health Inventory 13 were based on an English-speaking population, which may not be fully applicable to Chinese- and Spanish-speaking patients included in the study. Depression and anxiety were not evaluated by a mental health professional or with a structured interview to assess formal diagnostic criteria. Psychiatric medication used at the time of baseline GA was not included in the analysis. The study is a secondary analysis of a randomized controlled trial, and it is not known which components of the interventions affected mental health.

DISCLOSURES:

This research project was supported by the UniHealth Foundation, the City of Hope Center for Cancer and Aging, and the National Institutes of Health. One coauthor disclosed receiving institutional research funding from AstraZeneca and Brooklyn ImmunoTherapeutics and consulting for multiple pharmaceutical companies, including AbbVie, Adagene, and Bayer HealthCare Pharmaceuticals. William Dale, MD, PhD, of City of Hope National Medical Center, served as senior author and a principal investigator. Additional disclosures are noted in the original article.

  • Mental health was assessed using the Mental Health Inventory 13, and chemotherapy toxicity was graded by the National Cancer Institute Common Terminology Criteria for Adverse Events, version 4.0.
  • Patients in the intervention arm received recommendations from a multidisciplinary team based on their baseline GA, while those in the standard-of-care arm received only the baseline assessment results.
  • The study was conducted at City of Hope National Medical Center in Duarte, California, and patients were followed throughout treatment or for up to 6 months from starting chemotherapy.

TAKEAWAY:

  • According to the authors, patients with depression had increased chemotherapy toxicity in the standard-of-care arm (70.7% vs 54.3%; P = .02) but not in the GA-driven intervention arm (54.3% vs 48.5%; P = .27).
  • The association between depression and chemotherapy toxicity was also seen after adjustment for the Cancer and Aging Research Group toxicity score (odds ratio, [OR], 1.98; 95% CI, 1.07-3.65) and for demographic, disease, and treatment factors (OR, 2.00; 95% CI, 1.03-3.85).
  • No significant association was found between anxiety and chemotherapy toxicity in either the standard-of-care arm (univariate OR, 1.07; 95% CI, 0.61-1.88) or the GA-driven intervention arm (univariate OR, 1.15; 95% CI, 0.78-1.71).
  • The authors stated that depression was associated with increased odds of hematologic-only toxicities (OR, 2.50; 95% CI, 1.13-5.56) in the standard-of-care arm.
  • An analysis of a small subgroup found associations between elevated anxiety symptoms and increased risk for hematologic and nonhematologic chemotherapy toxicities.

IN PRACTICE:

“The current study showed that elevated depression symptoms are associated with increased risk of severe chemotherapy toxicities in older adults with cancer. This risk was mitigated in those in the GA intervention arm, which suggests that addressing elevated depression symptoms may lower the risk of toxicities,” the authors wrote. “Overall, elevated anxiety symptoms were not associated with risk for severe chemotherapy toxicity.”

LIMITATIONS:

The thresholds for depression and anxiety used in the Mental Health Inventory 13 were based on an English-speaking population, which may not be fully applicable to Chinese- and Spanish-speaking patients included in the study. Depression and anxiety were not evaluated by a mental health professional or with a structured interview to assess formal diagnostic criteria. Psychiatric medication used at the time of baseline GA was not included in the analysis. The study is a secondary analysis of a randomized controlled trial, and it is not known which components of the interventions affected mental health.

Electroconvulsive Therapy Works, Now Scientists Believe They Know How

For years, electroconvulsive therapy (ECT) has been a lifesaving treatment for patients with treatment-resistant depression (TRD), yet exactly how it works has largely remained a mystery. Now researchers believe they have uncovered the underlying mechanisms behind its therapeutic effects — a discovery that may help clinicians better predict treatment response in individual patients and quell much of the fear and stigma associated with one of psychiatry’s most effective, yet misunderstood, treatments.

Two recent papers published in Translational Psychiatry have highlighted the significance of aperiodic neural activity. The first study showed this activity increased following ECT treatment. The second study expanded on these data by demonstrating a significant increase in aperiodic activity after patients received either ECT or magnetic seizure therapy (MST), which has a better side-effect profile than ECT but lower efficacy.

Aperiodic activity is “like the brain’s background noise, and for years scientists treated it that way and didn’t pay much attention to it,” first author Sydney E. Smith, a PhD candidate at the Voytek Lab in the Neuroscience Graduate Program at the University of California San Diego (UCSD), said in a press release.

However, aperiodic activity boosts inhibitory activity in the brain, effectively slowing it down,” the investigators noted.

In an interview with this news organization, Ms. Smith used a car analogy to explain the mechanism behind ECT. “ECT might be increasing the activity levels in the brain cells that help calm it down. It taps on the brakes that tend to malfunction in depression. By restoring the balance between the gas and the brakes in the brain, some of those depressive symptoms are alleviated,” she said.

Ms. Smith added her team’s research helps demystify one of the most effective yet stigmatized treatments for severe depression.

“Aperiodic activity as a physiologically interpretable EEG metric could be a really valuable new predictive indicator for treatment response,” she added.
 

Fear and Stigma

ECT is primarily used for TRD and is effective in up to 80% of patients, yet it remains one of the least prescribed treatments.

Although it’s been around for almost 90 years, fear and concern about its potential cognitive side effects have contributed to its poor uptake. It is estimated that less than 1% of patients with TRD receive ECT.

Smith noted that the 1970s movie One Flew Over the Cuckoo’s Nest still contributes to ECT’s stigma. In the film, actor Jack Nicholson’s character is forced to undergo ECT as a punishment.

It’s important for clinicians to acknowledge the stigma while advising patients that “the actual treatment doesn’t look anything like what’s in the movies,” noted Ms. Smith. Patients must give informed consent for the procedure, and it’s delivered with the lowest level of effective stimulation.

“So many steps are taken to consider comfort and efficacy for patients and to minimize how scary it can be,” she said.

ECT uses an electrical current to induce a seizure that spreads to deep subcortical structures. MST, which was developed as an alternative to ECT, uses a magnetic field to induce a more focal seizure primarily confined to the cortex.

Although MST has a better side-effect profile, experts noted it has remission rates of 30%-60% compared with ECT. Even one of MST’s inventors, Harold Sackeim, PhD, professor in the Department of Psychiatry and Behavioral Sciences, Medical University of South Carolina, Charleston, is skeptical about its efficacy for TRD.

“I don’t think it works,” Dr. Sackeim, founding editor of Brain Stimulation: Basic, Translational, and Clinical Research in Neuromodulation, told this news organization.

In addition to being more expensive, MST produces a peak electrical intensity at one-tenth of what a typical ECT stimulus produces. “We’re limited by electrical engineering at this point with MST. That’s my view; others are more optimistic,” he said.
 

 

 

A Lifesaving Treatment

One of the reasons ECT isn’t more popular is because for many patients, it’s easier and more convenient to just take a pill, senior investigator Bradley Voytek, PhD, professor of cognitive science at UCSD, said in the release.

“However, in people for whom medications don’t work, [ECT] can be lifesaving. Understanding how it works will help us discover ways to increase the benefits while minimizing side effects,” he added.

In the first study, which included nine patients with major depressive disorder (MDD), EEG results showed an increase in aperiodic activity following ECT.

The investigators then wanted to test whether these findings could be replicated in a larger study. They retrospectively assessed two previous datasets — 1 of 22 patients with MDD who received ECT and 1 of 23 patients who received MST. After treatment, both groups showed increased aperiodic activity.

“Although not directly related to clinical efficacy in this dataset, increased aperiodic activity is linked to greater amounts of neural inhibition, which is suggestive of a potential shared neural mechanism of action across ECT and MST,” the investigators wrote.

The researchers noted that this increase in aperiodic activity is a more parsimonious explanation for observations of clinical slowing than delta band power or delta oscillations for both ECT and MST.”

So why is it important to know exactly how ECT works, and is there any clinical utility to these research findings?

“It’s important for clinicians to give a patient who has questions, a meaningful understanding of what the treatment is going to do, especially with something so scary and stigmatized. The ability to tell a patient why this treatment is working could provide a level of comfort that can assuage some of these fears,” Ms. Smith said.
 

A New Predictor of Response?

In addition, she noted that psychiatry is becoming more focused on predictive indicators for treatment.

“It’s asking: Are there any biological measures that can be used to predict whether someone is going to respond to a treatment or not?” said Ms. Smith.

“Aperiodic activity might be a valuable asset to add to that arsenal. Maybe we can better predict which patients might respond to ECT by using this as an additional biological indicator,” she added.

Smith noted that while more studies are needed, it’s exciting that some investigators are already starting to include aperiodic activity as a variable in their research analyses on a variety of topics, such as pharmacological intervention and transcranial magnetic stimulation.

“I don’t know exactly how much utility aperiodic activity is going to have in terms of being a great biological indicator, but I hope that the research will start to play out and reveal a little bit more,” she said.

Dr. Sackeim noted that ECT is one of the most misunderstood, controversial, and infrequently used treatments in psychiatry.

“But there’s also no doubt that when you look at ECT, it saves the lives of people with psychiatric illness. Period, full stop,” he said.

He added that although restarting a patient’s heart doesn’t seem to cause unease in the public, the idea of applying electricity to the brain under anesthesia in order to provoke a seizure for therapeutic purpose causes anxiety.

Still, the benefits and harms of a treatment are more important than how it looks, Sackeim said. “If it was only about how it looks, we’d never have surgery,” he added.
 

 

 

‘A Huge Success Story’

ECT was first introduced by Hungarian neuropsychiatrist László Meduna in 1935, and today clinicians “know where the current goes in the brain, at what dosage, and with what path you can get 70%, 80% fully remitted,” said Dr. Sackeim.

He noted that in a randomized study published in JAMA Psychiatry, investigators compared the outcomes of MST vs ECT for major depressive episodes in 73 patients. They reported that although depression symptom scores decreased for both treatments, there was “no significant difference” between the two in response or remission rates.

However, in an opinion letter the journal published in April, Dr. Sackeim and colleagues Mark S. George, MD, Medical University of South Carolina, and William V. McCall, MD, Augusta University, Augusta, Georgia, strongly questioned the findings.

At less than 30%, “the ECT remission rate after acute treatment was exceptionally low, limiting confidence in the validity and/or generalizability of the findings,” they wrote.

“It’s undoubtedly the case that either if you recruited a sample from whom the treatment may not be as efficacious or if there are issues in delivering them, then you may be finding equivalence” between ECT and MST, Dr. Sackeim said.

In addition, he noted that although there have been concerns about cognitive side effects with ECT, they have improved over the years. Sackeim reported that when he entered the field, the average time for a patient to remember their name or the day of the week was 6 hours after receiving unilateral ECT and 8 hours after bilateral ECT. “With modern methods, that’s now down to 10 minutes,” he said.

“The fundamental knowledge is that this treatment can be administered far softer than it ever was in the past. Impressions from the 50s and 60s and portrayed in movies have very little to do with modern practice and with the real effects of the treatment,” Dr. Sackeim said.

As for the new studies about aperiodic activity, the investigators are “essentially saying, ‘We have a better marker’ of the process. That way of thinking had in many ways been left behind in the run to study connectivity,” Dr. Sackeim said.

He noted that years ago, while he was with Columbia University, his team found that patients who had frontal inhibition were more likely to get well after ECT.

“And that’s essentially the same thing you’re hearing from the UCSD group. They’re saying that the aperiodic measure is hopefully of clearer physiological significance than simply delta [waves] in the EEG,” Dr. Sackeim said.

“The idea that inhibition was the key to its efficacy has been around. This is saying it’s a better measure of that, and that may be true. It’s certainly an interesting contribution,” he added.

Dr. Sackeim said the takeaway message for clinicians regarding ECT today is that it can be lifesaving but is still often only used as a last resort and reserved for those who have run out of options.

However, he said, ECT is “a huge success story: Maintaining its efficacy, reducing its side effects, getting an understanding as to what the physics of it are. We have some compelling stories about ECT, but even more so, we know what’s not true. And what’s not true are most of the assumptions people have about the treatment,” he concluded.

Ms. Smith and Dr. Voytek reported no relevant conflicts of interest. Dr. Sackeim reported holding patents in ECT technology and consulting with the MECTA Corporation and SigmaStim LLC and other neuromodulation companies.

“The idea that inhibition was the key to its efficacy has been around. This is saying it’s a better measure of that, and that may be true. It’s certainly an interesting contribution,” he added.

Dr. Sackeim said the takeaway message for clinicians regarding ECT today is that it can be lifesaving but is still often only used as a last resort and reserved for those who have run out of options.

However, he said, ECT is “a huge success story: Maintaining its efficacy, reducing its side effects, getting an understanding as to what the physics of it are. We have some compelling stories about ECT, but even more so, we know what’s not true. And what’s not true are most of the assumptions people have about the treatment,” he concluded.

Ms. Smith and Dr. Voytek reported no relevant conflicts of interest. Dr. Sackeim reported holding patents in ECT technology and consulting with the MECTA Corporation and SigmaStim LLC and other neuromodulation companies.

Cognitive Breakdown: The New Memory Condition Primary Care Needs to Know

Wed, 08/07/2024 - 12:15

Patients experiencing memory problems often come to neurologist David Jones, MD, for second opinions. They repeat questions and sometimes misplace items. Their primary care clinician has suggested they may have Alzheimer’s disease or something else.

In many cases, Dr. Jones, a neurologist with Mayo Clinic in Rochester, Minnesota, performs a series of investigations and finds the patient instead has a different type of neurodegenerative syndrome, one that progresses slowly, seems limited chiefly to loss of memory, and which tests show affects only the limbic system.

The news of diagnosis can be reassuring to patients.

“Memory problems are not always Alzheimer’s disease,” Dr. Jones said. “It’s important to broaden the differential diagnosis and seek diagnostic clarity and precision for patients who experience problems with brain functioning later in life.”

Dr. Jones and colleagues recently published clinical criteria for what they call limbic-predominant amnestic neurodegenerative syndrome (LANS).

Various underlying etiologies are known to cause degeneration of the limbic system, the most frequent being a buildup of deposits of the TAR DNA-binding protein 43 (TDP-43) protein referred to as limbic-predominant, age-related TDP-43 encephalopathy neuropathological change (LATE-NC). LATE-NC first involves the amygdala, followed by the hippocampus, and then the middle frontal gyrus, and is found in about 40% of autopsied brains in people over age of 85 years.

By contrast, amnestic syndromes originating from neocortical degeneration are largely caused by neuropathological changes from Alzheimer’s disease and often present with non-memory features.
 

Criteria for LANS

Broken down into core, standard, and advanced features

Core clinical features:

The patient must present with a slow, amnestic, predominant neurodegenerative syndrome — an insidious onset with gradual progression over 2 or more years — without another condition that better accounts for the clinical deficits.

Standard supportive features:

1. Older age at evaluation.

  • Most patients are at least the age of 75 years. Older age increases the likelihood that the amnestic syndrome is caused by degeneration of the limbic system.

2. Mild clinical syndrome.

  • A diagnosis of mild cognitive impairment or mild amnestic dementia (ie, a score of ≤ 4 on the Clinical Dementia Rating Sum of Boxes [CDR-SB]) at the first visit.

3. Hippocampal atrophy out of proportion to syndrome severity.

  • Hippocampal volume was smaller than expected on MRI, compared with the CDR-SB score.

4. Mildly impaired semantic memory.

Advanced supportive features:

1.Limbic hypometabolism and absence of neocortical degenerative pattern on fludeoxyglucose-18-PET imaging.

2. Low likelihood of significant neocortical tau pathology.


Dr. Jones and colleagues also classified a degree of certainty for LANS to use when making a diagnosis. Those with the highest likelihood meet all core, standard, and advanced features.

Patients with a high likelihood of having LANS meet core features, at least three standard features and one advanced feature; or meet core features, at least two standard features as well as two advanced features. Those with a moderate likelihood meet core features and at least three standard features or meet core features and at least two standard features and one advanced feature. Those with a low likelihood of LANS meet core features and two or fewer standard features.

To develop these criteria, the group screened 218 autopsied patients participating in databases for the Mayo Clinic Study of Aging and the multicenter Alzheimer’s Disease Neuroimaging Initiative. They conducted neuropathological assessments, reviewed MRI and PET scans of the brains, and studied fluid biomarkers from samples of cerebrospinal fluid.

In LANS, the neocortex exhibits normal function, Dr. Jones said. High-level language functions, visual spatial functions, and executive function are preserved, and the disease stays mild for many years. LANS is highly associated with LATE, for which no biomarkers are yet available.

The National Institute on Aging in May 2023 held a workshop on LATE, and a consensus group was formed to publish criteria to help with the diagnosis. Many LANS criteria likely will be in that publication as well, Dr. Jones said.

Several steps lay ahead to improve the definition of LANS, the authors wrote, including conducting prospective studies and developing clinical tools that are sensitive and specific to its cognitive features. The development of in vivo diagnostic markers of TDP-43 pathology is needed to embed LANS into a disease state driven by LATE-NC, according to Dr. Jones’ group. Because LANS is newly defined, clinical trials are needed to determine the best treatments.
 

 

 

Heterogeneous Dementia

“We are increasingly recognizing that the syndrome of dementia in older adults is heterogeneous,” said Sudha Seshadri, MD, DM, a behavioral neurologist and founding director of the Glenn Biggs Institute for Alzheimer’s and Neurodegenerative Diseases at the University of Texas Health Science Center at San Antonio.

LANS “is something that needs to be diagnosed early but also needs to be worked up in a nuanced manner, with assessment of the pattern of cognitive deficits, the pattern of brain shrinkage on MRI, and also how the disease progresses over, say, a year,” said Dr. Seshadri. “We need to have both some primary care physicians and geriatricians who are comfortable doing this kind of nuanced advising and others who may refer patients to behavioral neurologists, geriatricians, or psychiatrists who have that kind of expertise.”

About 10% of people presenting to dementia clinics potentially could fit the LANS definition, Dr. Seshadri said. Dr. Seshadri was not a coauthor of the classification article but sees patients in the clinic who fit this description.

“It may be that as we start more freely giving the diagnosis of a possible LANS, the proportion of people will go up,” Dr. Seshadri said.

Primary care physicians can use a variety of assessments to help diagnose dementias, she said. These include the Montreal Cognitive Assessment (MoCA), which takes about 10 minutes to administer, or an MRI to determine the level of hippocampal atrophy. Blood tests for p-tau 217 and other plasma tests can stratify risk and guide referrals to a neurologist. Clinicians also should look for reversible causes of memory complaints, such as deficiencies in vitamin B12, folate, or the thyroid hormone.

“There aren’t enough behavioral neurologists around to work up every single person who has memory problems,” Dr. Seshadri said. “We really need to partner on educating and learning from our primary care partners as to what challenges they face, advocating for them to be able to address that, and then sharing what we know, because what we know is an evolving thing.”

Other tools primary care clinicians can use in the initial evaluation of dementia include the General Practitioner Assessment of Cognition and the Mini-Cog, as part of annual Medicare wellness visits or in response to patient or caregiver concerns about memory, said Allison Kaplan, MD, a family physician at Desert Grove Family Medical in Gilbert, Arizona, who coauthored a point-of-care guide for the American Academy of Family Physicians. Each of these tests takes just 3-4 minutes to administer.

If a patient has a positive result on the Mini-Cog or similar test, they should return for further dementia evaluation using the MoCA, Mini-Mental State Examination, or Saint Louis University Mental Status examination, she said. Physicians also can order brain imaging and lab work, as Dr. Seshadri noted. Dementias often accompany some type of cardiovascular disease, which should be managed.

Even if a patient or family member doesn’t express concern about memory, physicians can look for certain signs during medical visits.

“Patients will keep asking the same question, or you notice they’re having difficulty taking care of themselves, especially independent activities of daily living, which could clue you in to a dementia diagnosis,” she said.

Dr. Jones ,Dr. Seshadri, and Dr. Kaplan disclosed no relevant financial relationships.
