Is Buprenorphine/Naloxone Safer Than Buprenorphine Alone During Pregnancy?
TOPLINE:
Buprenorphine combined with naloxone during pregnancy is associated with lower risks for neonatal abstinence syndrome and neonatal intensive care unit admission than buprenorphine alone. The study also found no significant differences in major congenital malformations between the two treatments.
METHODOLOGY:
- Researchers conducted a population-based cohort study using healthcare utilization data of people who were insured by Medicaid between 2000 and 2018.
- A total of 8695 pregnant individuals were included, with 3369 exposed to buprenorphine/naloxone and 5326 exposed to buprenorphine alone during the first trimester.
- Outcome measures included major congenital malformations, low birth weight, neonatal abstinence syndrome, neonatal intensive care unit admission, preterm birth, respiratory symptoms, small for gestational age, cesarean delivery, and maternal morbidity.
- The study excluded pregnancies with chromosomal anomalies, first-trimester exposure to known teratogens, or methadone use during baseline or the first trimester.
TAKEAWAY:
- According to the authors, buprenorphine/naloxone exposure during pregnancy was associated with a lower risk for neonatal abstinence syndrome (weighted risk ratio [RR], 0.77; 95% CI, 0.70-0.84) than buprenorphine alone.
- The researchers found a modestly lower risk for neonatal intensive care unit admission (weighted RR, 0.91; 95% CI, 0.85-0.98) and small risk for gestational age (weighted RR, 0.86; 95% CI, 0.75-0.98) in the buprenorphine/naloxone group.
- No significant differences were observed between the two groups in major congenital malformations, low birth weight, preterm birth, respiratory symptoms, or cesarean delivery.
IN PRACTICE:
“For the outcomes assessed, compared with buprenorphine alone, buprenorphine combined with naloxone during pregnancy appears to be a safe treatment option. This supports the view that both formulations are reasonable options for treatment of OUD in pregnancy, affirming flexibility in collaborative treatment decision-making,” the study authors wrote.
SOURCE:
The study was led by Loreen Straub, MD, MS, of the Division of Pharmacoepidemiology and Pharmacoeconomics at Brigham and Women’s Hospital and Harvard Medical School in Boston. It was published online in JAMA.
LIMITATIONS:
Some potential confounders, such as alcohol use and cigarette smoking, may not have been recorded in claims data. The findings for many of the neonatal and maternal outcomes suggest that confounding by unmeasured factors is an unlikely explanation for the associations observed. Individuals identified as exposed based on filled prescriptions might not have used the medication. The study used outcome algorithms with relatively high positive predictive values to minimize outcome misclassification. The cohort was restricted to live births to enable linkage to infants and to assess neonatal outcomes.
DISCLOSURES:
Various authors reported receiving grants and personal fees from the Eunice Kennedy Shriver National Institute of Child Health and Human Development, the National Institute on Drug Abuse, Roche, Moderna, Takeda, and Janssen Global, among others.

PCOS Increases Eating Disorder Risk
TOPLINE:
Women with polycystic ovary syndrome (PCOS) have higher odds of some eating disorders, including bulimia nervosa, binge eating disorder, and disordered eating, regardless of weight.
METHODOLOGY:
- A small systematic review and meta-analysis showed increased odds of any eating disorders and disordered eating scores in adult women with PCOS compared with women without PCOS.
- As part of the 2023 update of the International Evidence-based Guideline for the Assessment of and Management of PCOS, the same researchers updated and expanded their analysis to include adolescents and specific eating disorders and to evaluate the effect of body mass index (BMI) on these risks.
- They included 20 cross-sectional studies involving 28,922 women with PCOS and 258,619 women without PCOS; PCOS was diagnosed by either National Institutes of Health or Rotterdam criteria, as well as by patient self-report or hospital records.
- Eating disorders were screened using a validated disordered eating screening tool or diagnostic criteria from the Diagnostic and Statistical Manual of Mental Disorders.
- The outcomes of interest included the prevalence of any eating disorder, individual eating disorders, disordered eating, and mean disordered eating scores.
TAKEAWAY:
- Women with PCOS had 53% higher odds (odds ratio [OR], 1.53; 95% CI, 1.29-1.82; eight studies) of any eating disorder than control individuals without PCOS.
- The likelihood of bulimia nervosa (OR, 1.34; 95% CI, 1.17-1.54; five studies) and binge eating disorder (OR, 2.09; 95% CI, 1.18-3.72; four studies) was higher in women with PCOS, but no significant association was found for anorexia nervosa.
- The mean disordered eating scores and odds of disordered eating were higher in women with PCOS (standardized mean difference [SMD], 0.52; 95% CI, 0.28-0.77; 13 studies; and OR, 2.84; 95% CI, 1.0-8.04; eight studies; respectively).
- Disordered eating scores were higher in both the normal and higher weight categories (BMI < 25; SMD, 0.36; 95% CI, 0.15-0.58; five studies; and BMI ≥ 25; SMD, 0.68; 95% CI, 0.22-1.13; four studies; respectively).
IN PRACTICE:
“Our findings emphasize the importance of screening women with PCOS for eating disorders before clinicians share any lifestyle advice,” the lead author said in a press release. “The lifestyle modifications we often recommend for women with PCOS — including physical activity, healthy diet, and behavior modifications — could hinder the recovery process for eating disorders.”
SOURCE:
The study was led by Laura G. Cooney, MD, MSCE, University of Wisconsin, Madison, and published online in the Journal of Clinical Endocrinology & Metabolism.
LIMITATIONS:
The included studies were observational in nature, limiting the ability to adjust for potential confounders. The cross-sectional design of the included studies precluded determining whether the diagnosis of PCOS or the symptoms of disordered eating occurred first. Studies from 10 countries were included, but limited data from developing or Asian countries restrict the generalizability of the results.
DISCLOSURES:
This study was conducted to inform recommendations of the 2023 International Evidence-based Guideline in PCOS, which was funded by the Australian National Health and Medical Research Council, Centre for Research Excellence in Polycystic Ovary Syndrome, and other sources. The authors declared no conflicts of interests.

Sexual Arousal Cream Promising in Some Subsets of Women
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.”
, 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.

How Safe is Anti–IL-6 Therapy During Pregnancy?
TOPLINE:
The maternal and neonatal outcomes in pregnant women treated with anti–interleukin (IL)-6 therapy for COVID-19 are largely favorable, with transient neonatal cytopenia observed in around one third of the babies being the only possible adverse outcome that could be related to anti–IL-6 therapy.
METHODOLOGY:
- Despite guidance, very few pregnant women with COVID-19 are offered evidence-based therapies such as anti–IL-6 due to concerns regarding fetal safety in later pregnancy.
- In this retrospective study, researchers evaluated maternal and neonatal outcomes in 25 pregnant women with COVID-19 (mean age at admission, 33 years) treated with anti–IL-6 (tocilizumab or sarilumab) at two tertiary hospitals in London.
- Most women (n = 16) received anti–IL-6 in the third trimester of pregnancy, whereas nine received it during the second trimester.
- Maternal and neonatal outcomes were assessed through medical record reviews and maternal medicine networks, with follow-up for 12 months.
- The women included in the study constituted a high-risk population with severe COVID-19; 24 required level two or three critical care. All women were receiving at least three concomitant medications due to their critical illness.
TAKEAWAY:
- Overall, 24 of 25 women treated with IL-6 receptor antibodies survived until hospital discharge.
- The sole death occurred in a woman with severe COVID-19 pneumonitis who later developed myocarditis and cardiac arrest. The physicians believed that these complications were more likely due to severe COVID-19 rather than anti–IL-6 therapy.
- All pregnancies resulted in live births; however, 16 babies had to be delivered preterm due to COVID-19 complications.
- Transient cytopenia was observed in 6 of 19 babies in whom a full blood count was performed. All the six babies were premature, with cytopenia resolving within 7 days in four babies; one baby died from complications associated with extreme prematurity.
IN PRACTICE:
“Although the authors found mild, transitory cytopenia in some (6 of 19) exposed infants, most had been delivered prematurely due to progressive COVID-19–related morbidity, and distinguishing drug effects from similar prematurity-related effects is difficult,” wrote Steven L. Clark, MD, from the Department of Obstetrics and Gynecology, Baylor College of Medicine, Houston, in an accompanying editorial.
SOURCE:
The study was led by Melanie Nana, MRCP, from the Department of Obstetric Medicine, St Thomas’ Hospital, London, England. It was published online in The Lancet Rheumatology.
LIMITATIONS:
The study was retrospective in design, which may have introduced bias. The small sample size of 25 women may have limited the generalizability of the findings. Additionally, the study did not include a control group, which made it difficult to attribute outcomes solely to anti–IL-6 therapy. The lack of long-term follow-up data on the neonates also limited the understanding of potential long-term effects.
DISCLOSURES:
This study did not receive any funding. Some authors, including the lead author, received speaker fees, grants, or consultancy fees from academic institutions or pharmaceutical companies or had other ties with various sources.

TOPLINE:
The maternal and neonatal outcomes in pregnant women treated with anti–interleukin (IL)-6 therapy for COVID-19 are largely favorable, with transient neonatal cytopenia observed in around one third of the babies being the only possible adverse outcome that could be related to anti–IL-6 therapy.

More Access to Perinatal Mental Healthcare Needed
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
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, reports, law 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
“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.

“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.

Modest Gains Shown in Breast Cancer Immunotherapy Trials
TOPLINE:
particularly among single-center studies which are more likely to go unreported, and many phase 2 studies failing to translate into successful phase 3 trials.
METHODOLOGY:
- Few immunotherapy agents — only pembrolizumab in the United States, as of December 2023, and atezolizumab in Europe — have received approvals for use in patients with breast cancer, indicating low returns on the large number of breast cancer immunotherapy trials launched in the early 2010s.
- In this cross-sectional study, researchers evaluated 331 immunotherapy trials, initiated between January 2004 and April 2023, that enrolled 48,844 patients with breast cancer.
- Of these, 47 were phase 1 trials, 242 were phase 2 trials, and 42 were phase 3 trials.
- A trial was considered reported if the results were posted on ClinicalTrial.gov or reported as an abstract or a manuscript.
- Overall, 120 trials met their completion date up to November 2022; of these, 30 (25%) failed to report outcomes, which included two phase 3 trials.
TAKEAWAY:
- Phase 1 trials had the highest rate of nonreporting (31.8%), followed by phase 2 (23.6%) and phase 3 (22.2%) trials.
- Single-center studies were more likely to be unreported than multicenter studies (35.2% vs 15.0%; P = .02).
- Of 90 reported trials, 47 (52.2%) met their primary endpoints and 43 (47.8%) did not.
- The majority, 17 out of 19 (89.5%), of the reported randomized trials had negative results.
IN PRACTICE:
“The findings of this study suggest that the large number of immunotherapy trials being run have yielded modest clinical impact,” the authors wrote. “More selective initiation of phase 2 trials, grounded in preclinical and biomarker observations and with optimal statistical designs for early efficacy assessment, is needed to increase trial efficiency.”
SOURCE:
The study, led by Marco Mariani, MD, Università Vita-Salute San Raffaele, Milan, Italy, was published online in JAMA Network Open.
LIMITATIONS:
The study’s reliance on ClinicalTrials.gov as the primary source of trial data might have resulted in some trials being overlooked. In addition, manual data extraction could cause inaccuracies and potentially introduced biases in the interpretation of trial results. Primary study completion date cutoff of December 2022 could have excluded significant data from more recent trials.

Can Addressing Depression Reduce Chemo Toxicity in Older Adults?
TOPLINE:
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.”

It’s in the Juice: Cranberries for UTI Prevention
TOPLINE:
A systematic review and network meta-analysis found cranberry juice can help prevent urinary tract infections (UTIs).
METHODOLOGY:
- With an increasing prevalence of antimicrobial resistance and over 50% women reporting at least one episode of UTI each year, identifying evidence supporting possible nondrug interventions is necessary, according to the study researchers from Bond University, the University of Helsinki, and the University of Oxford.
- The primary study outcome was number of UTIs in each treatment or placebo group; the secondary outcomes were UTI symptoms such as increased bladder sensation, urgency, frequency, dysuria, and consumption of antimicrobial drugs.
- Studies analyzed included people of any age and gender at a risk for UTI.
- Researchers included 3091 participants from 18 randomized controlled trials and two nonrandomized controlled trials.
TAKEAWAY:
- Studies used one of the following interventions: Cranberry nonliquid products (tablet, capsule, or fruit), cranberry liquid, liquid other than cranberry, and no treatment.
- A total of 18 studies showed a 27% lower rate of UTIs with the consumption of cranberry juice than with placebo liquid (moderate certainty evidence) and a 54% lower rate of UTIs with the consumption of cranberry juice than with no treatment (very low certainty evidence).
- Based on a meta-analysis of six studies, antibiotic use was 49% lower with the consumption of cranberry juice than with placebo liquid and 59% lower than with no treatment.
- Cranberry compounds also were associated with a decrease in prevalence of UTI symptoms.
IN PRACTICE:
“The evidence supports the use of cranberry juice for the prevention of UTIs. While increased liquids benefit the rate of UTIs and reduce antibiotic use, and cranberry compounds benefit symptoms of infection, the combination of these, in cranberry juice, provides clear and significant clinical outcomes for the reduction in UTIs and antibiotic use and should be considered for the management of UTIs,” the authors wrote.
SOURCE:
The study was led by Christian Moro, PhD, faculty of health sciences and medicine at Bond University in Gold Coast, Australia, and was published online in European Urology Focus on July 18, 2024.
LIMITATIONS:
The authors noted that some planned findings such as the impact on antibiotic use were reduced due to limited studies. Some studies on cranberry tablets also provided education with the intervention, which could have affected UTI recurrence rates. Nearly all the 20 studies that were analyzed included mostly women; thus, comparisons between genders were not possible.
DISCLOSURES:
Dr. Moro reported no disclosures.

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

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.
