Men Wanted: New Efforts to Attract Male Nurses
Only 12% of the nurses providing patient care at hospitals and health clinics today are men. Although the percentage of nurses has increased — men made up just 2.7% of nurses in 1970 — nursing is still considered a “pink collar” profession, a female-dominated field.
“We’ve made strides over the last couple of decades, but [the number of men pursuing nursing careers] is leveling out,” said Jason Dunne, DNP, MSN, RN, chief academic officer at the Arizona College of Nursing, Phoenix. “There continues to be persistent gender stereotypes that [have] discouraged men from entering the profession.”
“The nursing shortage is very real,” Dunne said. “We need to be highly focused on the shortage and look at opportunities to bring diversity into the profession, and one big way to solve it is bringing more men into nursing.”
Representation Matters
Colleges recognize the need to diversify their nursing student population and have turned their attention to increasing the number of men attending informational sessions and career days. Dunne believes, “There is a general lack of awareness of nursing as a career choice [for men].”
The Nursing Consortium of Florida hosts a “Day in the Life of a Nurse” program to introduce high school students to nursing careers, and the University of Virginia School of Nursing invites male nursing students to speak at educational events to promote workforce diversity.
“When I was growing up, the males wouldn’t have been included in those sessions,” said Melissa Gilbert Gomes, PhD, APRN, PMHNP-BC, FNAP, FAAN, associate dean for diversity, equity, and inclusion at the University of Virginia School of Nursing, Charlottesville, Virginia. “It was nice to see their interest and to have a male student there for them to ask questions and to help them see that this could be a place for them.”
Nursing schools have also engaged in other efforts to encourage more men to consider nursing careers, from highlighting male nurses in marketing materials and engaging with men at career fairs to updating course curriculum to include content on men’s health and connecting male nursing students with men in nursing faculty or clinical settings.
Focusing on nursing as a lucrative career choice could also attract more men to the profession. On average, male registered nurses (RNs) make $7300 per year more than their female counterparts due to the gender pay gap. The median wage for male RNs in acute care, cardiology, and perioperative specialties is $90,000 annually.
At the University of Virginia School of Nursing, which the American Association for Men in Nursing (AAMN) named “Best School for Men in Nursing” in 2023, 20% of nursing students are men.
The school has a Men Advancing Nursing club and is in the process of chartering a new AAMN chapter. The goal, according to Gomes, is to create an environment where male nursing students feel represented and supported.
“Valuing the perspective that men bring [to nursing] is important,” she said. “Coming together [and] having that camaraderie and intrinsic motivation to specifically speak to areas that impact men ... is important.”
Promoting Patient Care
Highlighting the diversity of career options within the nursing profession is also essential. RNs can pursue careers in specialties ranging from pediatrics, orthopedics, and occupational health to anesthesia, cardiology, and nephrology. The specialty with the highest number of male RNs tends to be acute care, which encompasses emergency/trauma and medical-surgical.
John Schmidt, DNP, MSN, BSN, faculty member and program lead for the acute care nurse practitioner program at Purdue Global School of Nursing, refers to these specialties as having a high excitement factor.
“Men gravitate to nursing to help people,” he said. “In critical care, there is instant gratification. You see patients get better. It’s the same in the [intensive care unit] and the emergency department. We take care of them and can see how we made a difference.”
When hospitals and health systems create environments that support men in nursing, patients also benefit. Research shows that patients often prefer nurses of the same gender, and a more diverse healthcare workforce has been linked to improved patient outcomes. Reducing gender inequities among nursing staff could also improve job satisfaction and retention rates for men in nursing.
“When you’re in a vulnerable space as a patient ... it’s important to know that your care provider understands you [and] having men as nurses is a part of that,” said Gomes. “Even though patients might not be used to having a male nurse at the bedside, once they have the experience, it challenges preconceived notions [and] that connection is important.”
Hospitals must proactively support men in nursing to achieve the benefits of greater gender diversity in the nursing workforce. Male nurses have fewer role models and report higher levels of loneliness, isolation, and role strain.
Groups such as NYC Men in Nursing and mentorship programs such as Men in Nursing at RUSH University College of Nursing and RUSH University Medical Center, and the North Carolina Healthcare Association Diverse Healthcare Leaders Mentorship Program were designed to provide coaching, education, and networking opportunities and connect men in nursing.
Male nurses, Dunne added, must be role models and must take the lead in changing the conversations about gender roles in nursing. Establishing support systems and mentorship opportunities is instrumental in inspiring men to pursue nursing careers and creating visibility into the profession and “would create a level of parity for men in the profession and encourage them to want to stay in nursing as a long-term career.”
He told this news organization that creating scholarships for men enrolled in nursing school, increasing the involvement of male nurse leaders in recruitment efforts, and updating curriculum to ensure men are reflected in the materials is also essential.
“We’ve got to be willing and open to having the conversations to end the stereotypes that have plagued the profession,” said Dunne. “And we’ve got to push men in nursing to be front and center so folks see that there are opportunities for men in nursing.”

Lawmakers Rush to Stave Off Doctor Pay Cuts as Medicare Finalizes 2025 Rates
Federal lawmakers are rushing to soften the blow of Medicare’s 2025 effective pay cut for doctors in 2025, introducing a bill that could limit the cut. But they have little time to act.
In 2025, the conversion factor used to calculate payment to doctors and hospitals caring for Medicare patients will drop to $32.35, a nearly 3% decrease from the current level.
Congress likely will act before the cuts take effect, said Rep. Larry Bucshon, MD (R-IN), who specialized in cardiothoracic surgery before joining Congress. Lawmakers in past years have typically tinkered with the Medicare physician fee schedule at the last minute, tucking in fixes to December legislative packages and spending bills.
“I’m pretty optimistic that a good portion of the fee cuts will be mitigated and they won’t go through,” Bucshon told this news organization in an interview.
Bruce A. Scott, MD, president of the American Medical Association (AMA) said in a statement that CMS’ release of the final fee schedule on November 1 should trigger serious work on a change to the 2025 Medicare physician fee schedule.
“The fee schedule rule released [on November 1] starts the clock — with January 1 looming,” Scott said. “A legislative remedy will require hard work and compromise. The 66 million patients who rely on Medicare are counting on that.”
Both Bucshon and Scott also joined many lawmakers and medical associations in calling on Congress for a larger overhaul of the Medicare physician fee schedule, well beyond whatever temporary adjustment may be made in the months ahead to avoid or soften the 2025 cuts.
The physician fee schedule sets formulas and rules regarding how the largest US buyer of health services pays the almost 1.3 million clinicians who bill Medicare. Of these, 51% are physicians. The physician fee schedule also covers payments for nurse practitioners, physician assistants, physical therapists, and other health professionals.
Last Major Overhaul Unpopular
There’s broad dissatisfaction with Congress’ last major overhaul of the Medicare physician fee schedule. The 2015 Medicare Access and CHIP Reauthorization Act (MACRA) aimed to shift clinicians toward programs tying pay increases to quality measures. But the implementation of that aim through the Merit-based Incentive Payment System is widely considered a disappointment.
MACRA was intended to end the need for annual “doc fixes,” as Congress’ last-minute Medicare adjustments are known. Seventeen such tweaks passed before MACRA took effect.
But MACRA did not include a broad-based inflation adjuster, and some clinicians’ incomes are lagging as inflation rates — and practice costs — have risen. Scott said the Medicare Economic Index, which is a measure used to gauge increases in practice costs for clinicians, is expected to rise by 3.5%.
“To put it bluntly, Medicare plans to pay us less while costs go up. You don’t have to be an economist to know that is an unsustainable trend, though one that has been going on for decades,” Scott said. “For physician practices operating on small margins already, this means it is harder to acquire new equipment, harder to retain staff, harder to take on new Medicare patients, and harder to keep the doors open, particularly in rural and underserved areas.”
In a statement, Jen Brull, MD, president of the American Academy of Family Physicians, noted that this likely will be the fifth year in a row that Congress will need to do a patch to prevent cuts in pay to clinicians.
Bucshon, who will retire from the House in January, said he expects Congress to pass legislation tying Medicare payment rates to inflation — eventually.
“People want to find a way to fix this problem, but also do it in a way that does not cut benefits to anyone, and that’s the key,” Bucshon said. “We’re going to have to find a way to make sure that providers are properly reimbursed.”

Being a Weekend Warrior Linked to Lower Dementia Risk
TOPLINE:
, a new study shows. Investigators say the findings suggest even limited physical activity may offer protective cognitive benefits.
METHODOLOGY:
- Researchers analyzed the data of 10,033 participants in the Mexico City Prospective Study who were aged 35 years or older.
- Physical activity patterns were categorized into four groups: No exercise, weekend warriors (one or two sessions per week), regularly active (three or more sessions per week), and a combined group.
- Cognitive function was assessed using the Mini-Mental State Examination (MMSE).
- The analysis adjusted for confounders such as age, sex, education, income, blood pressure, smoking status, body mass index, civil status, sleep duration, diet, and alcohol intake.
- The mean follow-up duration was 16 years.
TAKEAWAY:
- When mild dementia was defined as an MMSE score ≤ 22, dementia prevalence was 26% in those who did not exercise, 14% in weekend warriors, and 18.5% in the regularly active group.
- When mild dementia was defined as an MMSE score ≤ 23, dementia prevalence was 30% in those who did not exercise, 20% in weekend warriors, and 22% in the regularly active group.
- Compared with people who did not exercise and after adjusting for confounding factors, risk for mild dementia was 13%-25% lower in weekend warriors, 11%-12% lower in the regular activity group, and 12%-16% lower in the two groups combined.
- The findings were consistent in men and women.
IN PRACTICE:
“To the best of our knowledge, this is the first prospective cohort study to show that the weekend warrior physical activity pattern and the regularly active physical activity pattern are associated with similar reductions in the risk of mild dementia. This study has important implications for policy and practice because the weekend warrior physical activity pattern may be a more convenient option for busy people around the world,” the authors wrote.
SOURCE:
The study was led by Gary O’Donovan, Faculty of Medicine, University of the Andes, Bogotá, Colombia. It was published online in the British Journal of Sports Medicine.
LIMITATIONS:
The survey respondents may not have been truly representative of middle-aged adults. Further, there were no objective measures of physical activity. The observational nature of the study does not provide insights into causality.
DISCLOSURES:
The study was funded by the Mexican Health Ministry, the National Council of Science and Technology for Mexico, Wellcome, and the UK Medical Research Council. No conflicts of interest were disclosed.
This article was created using several editorial tools, including AI, as part of the process. Human editors reviewed this content before publication.

- Compared with people who did not exercise and after adjusting for confounding factors, risk for mild dementia was 13%-25% lower in weekend warriors, 11%-12% lower in the regular activity group, and 12%-16% lower in the two groups combined.
- The findings were consistent in men and women.
IN PRACTICE:
“To the best of our knowledge, this is the first prospective cohort study to show that the weekend warrior physical activity pattern and the regularly active physical activity pattern are associated with similar reductions in the risk of mild dementia. This study has important implications for policy and practice because the weekend warrior physical activity pattern may be a more convenient option for busy people around the world,” the authors wrote.

Cannabis Use Linked to Brain Thinning in Adolescents
, research in mice and humans suggested.
The multilevel study demonstrated that tetrahydrocannabinol (THC), an active substance in cannabis, causes shrinkage of dendritic arborization — the neurons’ network of antennae that play a critical role in communication between brain cells.
The connection between dendritic arborization and cortical thickness was hinted at in an earlier study by Tomáš Paus, MD, PhD, professor of psychiatry and addictology at the University of Montreal, Quebec, Canada, and colleagues, who found that cannabis use in early adolescence was associated with lower cortical thickness in boys with a high genetic risk for schizophrenia.
“We speculated at that time that the differences in cortical thickness might be related to differences in dendritic arborization, and our current study confirmed it,” Paus said.
That confirmation came in the mouse part of the study, when coauthor Graciela Piñeyro, MD, PhD, also of the University of Montreal, counted the dendritic branches of mice exposed to THC and compared the total with the number of dendritic branches in unexposed mice. “What surprised me was finding that THC in the mice was targeting the same type of cells and structures that Dr. Paus had predicted would be affected from the human studies,” she said. “Structurally, they were mostly the neurons that contribute to synapses in the cortex, and their branching was reduced.”
Paus explained that in humans, a decrease in input from the affected dendrites “makes it harder for the brain to learn new things, interact with people, cope with new situations, et cetera. In other words, it makes the brain more vulnerable to everything that can happen in a young person’s life.”
The study was published online on October 9 in the Journal of Neuroscience.
Of Mice, Men, and Cannabis
Although associations between cannabis use by teenagers and variations in brain maturation have been well studied, the cellular and molecular underpinnings of these associations were unclear, according to the authors.
To investigate further, they conducted this three-step study. First, they exposed adolescent male mice to THC or a synthetic cannabinoid (WIN 55,212-2) and assessed differentially expressed genes, spine numbers, and the extent of dendritic complexity in the frontal cortex of each mouse.
Next, using MRI, they examined differences in cortical thickness in 34 brain regions in 140 male adolescents who experimented with cannabis before age 16 years and 327 who did not.
Then, they again conducted experiments in mice and found that 13 THC-related genes correlated with variations in cortical thickness. Virtual histology revealed that these 13 genes were coexpressed with cell markers of astrocytes, microglia, and a type of pyramidal cell enriched in genes that regulate dendritic expression.
Similarly, the WIN-related genes correlated with differences in cortical thickness and showed coexpression patterns with the same three cell types.
Furthermore, the affected genes were also found in humans, particularly in the thinner cortical regions of the adolescents who experimented with cannabis.
By acting on microglia, THC seems to promote the removal of synapses and, eventually, the reduction of the dendritic tree in mice, Piñeyro explained. That’s important not only because a similar mechanism may be at work in humans but also because “we now might have a model to test different types of cannabis products to see which ones are producing the greatest effect on neurons and therefore greater removal of synapses through the microglia. This could be a way of testing drugs that are out in the street to see which would be the most or least dangerous to the synapses in the brain.”
‘Significant Implications’
Commenting on the study, Yasmin Hurd, PhD, Ward-Coleman chair of translational neuroscience at the Icahn School of Medicine at Mount Sinai and director of the Addiction Institute of Mount Sinai in New York City, said, “These findings are in line with previous results, so they are feasible. This study adds more depth by showing that cortical genes that were differentially altered by adolescent THC correlated with cannabis-related changes in cortical thickness based on human neuroimaging data.” Hurd did not participate in the research.
“The results emphasize that consumption of potent cannabis products during adolescence can impact cortical function, which has significant implications for decision-making and risky behavior as well. It also can increase vulnerability to psychiatric disorders such as schizophrenia.”
Although a mouse model is “not truly the same as the human condition, the fact that the animal model also showed evidence of the morphological changes indicative of reduced cortical thickness, [like] the humans, is strong,” she said.
Additional research could include women and assess potential sex differences, she added.
Ronald Ellis, MD, PhD, an investigator in the Center for Medicinal Cannabis Research at the University of California, San Diego School of Medicine, said, “The findings are plausible and extend prior work showing evidence of increased risk for psychotic disorders later in life in adolescents who use cannabis.” Ellis did not participate in the research.
“Future studies should explore how these findings might vary across different demographic groups, which could provide a more inclusive understanding of how cannabis impacts the brain,” he said. “Additionally, longitudinal studies to track changes in the brain over time could help to establish causal relationships more robustly.
“The take-home message to clinicians at this point is to discuss cannabis use history carefully and confidentially with adolescent patients to better provide advice on its potential risks,” he concluded.
Paus added that he would tell patients, “If you’re going to use cannabis, don’t start early. If you have to, then do so in moderation. And if you have family history of mental illness, be very careful.”
No funding for the study was reported. Paus, Piñeyro, Hurd, and Ellis declared having no relevant financial relationships.

No Benefit to High-Dose IV Vs Oral Steroids in Giant Cell Arteritis
TOPLINE:
In patients with giant cell arteritis (GCA), intravenous methylprednisolone compared with oral glucocorticoids alone does not improve visual acuity and increases the risk for diabetes within the first year. Survival rates do not differ with these two treatments.
METHODOLOGY:
- Researchers conducted a population-based retrospective study at three centers in Sweden to assess the clinical characteristics, treatment-related toxicity, and mortality in patients with GCA who were receiving high-dose intravenous methylprednisolone.
- A total of 419 patients with biopsy-confirmed GCA (mean age at diagnosis, 75 years; 69% women) diagnosed from 2004 to 2019 were included.
- Patients were treated with either intravenous methylprednisolone (n = 111) at a dose of 500-1000 mg per day for 3 consecutive days or oral glucocorticoids alone (n = 308).
- Ischemic visual complications considered to indicate visual involvement were confirmed by an ophthalmologist, and data on visual acuity were collected from ophthalmologic clinic records at initial consultations and follow-up at 3-18 months.
TAKEAWAY:
- Despite a tendency toward improvement, no significant difference in visual acuity was observed with intravenous methylprednisolone compared with oral glucocorticoids.
- Patients treated with intravenous methylprednisolone had a higher risk for newly diagnosed diabetes within a year of GCA diagnosis (odds ratio [OR], 2.59; P = .01).
- The risk for diabetes remained elevated even after adjustment for the cumulative oral glucocorticoid dose at 3 months (adjusted OR, 3.30; P = .01).
- Survival rates did not significantly differ between the treatment groups over a mean follow-up of 6.6 years.
IN PRACTICE:
“In this study on the use of intravenous methylprednisolone treatment in GCA, we found no evidence of a beneficial effect in improving visual acuity or enabling more rapid tapering of the oral glucocorticoid dose,” the authors wrote. “The use of IVMP [intravenous methylprednisolone] was associated with an increased risk of diabetes during the first year compared with oral GC [glucocorticoid], raising questions about the value of IVMP in GCA treatment.”
SOURCE:
The study, led by Hampus Henningson, Department of Clinical Sciences, Rheumatology, Lund University, Lund, Sweden, was published online in Rheumatology.
LIMITATIONS:
The retrospective nature of the study may have resulted in missing data and difficulty in accurately quantifying the cumulative glucocorticoid doses. The study did not validate the diagnoses of comorbidities but relied solely on diagnostic codes.

Novel Intervention Slows Cognitive Decline in At-Risk Adults
new research suggests.
The cognitive remediation intervention included a series of progressively difficult computer-based and facilitator-monitored mental exercises designed to sharpen cognitive function.
Researchers found that using cognitive remediation with tDCS slowed decline in executive function and verbal memory more than other cognitive functions. The effect was stronger among people with rMDD versus those with MCI and in those at low genetic risk for Alzheimer’s disease.
“We have developed a novel intervention, combining two interventions that if used separately have a weak effect but together have substantial and clinically meaningful effect of slowing the progression of cognitive decline,” said study author Benoit H. Mulsant, MD, chair of the Department of Psychiatry, University of Toronto, Ontario, Canada, and senior scientist at the Center for Addiction and Mental Health, also in Toronto.
The findings were published online in JAMA Psychiatry.
High-Risk Group
Research shows that older adults with MDD or MCI are at high risk for cognitive decline and dementia. Evidence also suggests that depression in early or mid-life significantly increases the risk for dementia in late life, even if the depression has been in remission for decades.
A potential mechanism underlying this increased risk for dementia could be impaired cortical plasticity, or the ability of the brain to compensate for damage.
The PACt-MD trial included 375 older adults with rMDD, MCI, or both (mean age, 72 years; 62% women) at five academic hospitals in Toronto.
Participants received either cognitive remediation plus tDCS or sham intervention 5 days per week for 8 weeks (acute phase), followed by 5-day “boosters” every 6 months.
tDCS was administered by trained personnel and involved active stimulation for 30 minutes at the beginning of each cognitive remediation group session. The intervention targets the prefrontal cortex, a critical region for cognitive compensation in normal cognitive aging.
The sham group received a weakened version of cognitive remediation, with exercises that did not get progressively more difficult. For the sham stimulation, the current flowed at full intensity for only 54 seconds before and after 30-second ramp-up and ramp-down phases, to create a blinding effect, the authors noted.
A geriatric psychiatrist followed all participants throughout the study, conducting assessments at baseline, month 2, and yearly for 3-7 years (mean follow-up, 48.3 months).
Participants’ depressive symptoms were evaluated at baseline and at all follow-ups and underwent neuropsychological testing to assess six cognitive domains: processing speed, working memory, executive functioning, verbal memory, visual memory, and language.
To get a norm for the cognitive tests, researchers recruited a comparator group of 75 subjects similar in age, gender, and years of education, with no neuropsychiatric disorder or cognitive impairment. They completed the same assessments but not the intervention.
Study participants and assessors were blinded to treatment assignment.
Slower Cognitive Decline
Participants in the intervention group had a significantly slower decline in cognitive function, compared with those in the sham group (adjusted z score difference [active – sham] at month 60, 0.21; P = .006). This is equivalent to slowing cognitive decline by about 4 years, researchers reported. The intervention also showed a positive effect on executive function and verbal memory.
“If I can push dementia from 85 to 89 years and you die at 86, in practice, I have prevented you from ever developing dementia,” Mulsant said.
The efficacy of cognitive remediation plus tDCS in rMDD could be tied to enhanced neuroplasticity, said Mulsant.
The treatment worked well in people with a history of depression, regardless of MCI status, but was not as effective for people with just MCI, researchers noted. The intervention also did not work as well among people at genetic risk for Alzheimer’s disease.
“We don’t believe we have discovered an intervention to prevent dementia in people who are at high risk for Alzheimer disease, but we have discovered an intervention that could prevent dementia in people who have an history of depression,” said Mulsant.
These results suggest the pathways to dementia among people with MCI and rMDD are different, he added.
Because previous research showed either treatment alone demonstrated little efficacy, researchers said the new results indicate that there may be a synergistic effect of combining the two.
The ideal amount of treatment and optimal age for initiation still need to be determined, said Mulsant. The study did not include a comparator group without rMDD or MCI, so the observed cognitive benefits might be specific to people with these high-risk conditions. Another study limitation is lack of diversity in terms of ethnicity, race, and education.
Promising, Important Findings
Commenting on the research, Badr Ratnakaran, MD, assistant professor and division director of geriatric psychiatry at Carilion Clinic–Virginia Tech Carilion School of Medicine, Roanoke, said the results are promising and important because there are so few treatment options for the increasing number of older patients with depression and dementia.
The side-effect profile of the combined treatment is better than that of many pharmacologic treatments, Ratnakaran noted. As more research like this comes out, Ratnakaran predicts that cognitive remediation and tCDS will become more readily available.
“This is telling us that the field of psychiatry, and also dementia, is progressing beyond your usual pharmacotherapy treatments,” said Ratnakaran, who also is chair of the American Psychiatric Association’s Council on Geriatric Psychiatry.
The study received support from the Canada Brain Research Fund of Brain Canada, Health Canada, the Chagnon Family, and the Centre for Addiction and Mental Health Discovery Fund. Mulsant reported holding and receiving support from the Labatt Family Chair in Biology of Depression in Late-Life Adults at the University of Toronto; being a member of the Center for Addiction and Mental Health Board of Trustees; research support from Brain Canada, Canadian Institutes of Health Research, Center for Addiction and Mental Health Foundation, Patient-Centered Outcomes Research Institute, and National Institutes of Health; and nonfinancial support from Capital Solution Design and HappyNeuron. Ratnakaran reported no relevant conflicts.

Study participants and assessors were blinded to treatment assignment.
Slower Cognitive Decline
Participants in the intervention group had a significantly slower decline in cognitive function, compared with those in the sham group (adjusted z score difference [active – sham] at month 60, 0.21; P = .006). This is equivalent to slowing cognitive decline by about 4 years, researchers reported. The intervention also showed a positive effect on executive function and verbal memory.
“If I can push dementia from 85 to 89 years and you die at 86, in practice, I have prevented you from ever developing dementia,” Mulsant said.
The efficacy of cognitive remediation plus tDCS in rMDD could be tied to enhanced neuroplasticity, said Mulsant.
The treatment worked well in people with a history of depression, regardless of MCI status, but was not as effective for people with just MCI, researchers noted. The intervention also did not work as well among people at genetic risk for Alzheimer’s disease.
“We don’t believe we have discovered an intervention to prevent dementia in people who are at high risk for Alzheimer disease, but we have discovered an intervention that could prevent dementia in people who have an history of depression,” said Mulsant.
These results suggest the pathways to dementia among people with MCI and rMDD are different, he added.
Because previous research showed either treatment alone demonstrated little efficacy, researchers said the new results indicate that there may be a synergistic effect of combining the two.
The ideal amount of treatment and optimal age for initiation still need to be determined, said Mulsant. The study did not include a comparator group without rMDD or MCI, so the observed cognitive benefits might be specific to people with these high-risk conditions. Another study limitation is lack of diversity in terms of ethnicity, race, and education.
Promising, Important Findings
Commenting on the research, Badr Ratnakaran, MD, assistant professor and division director of geriatric psychiatry at Carilion Clinic–Virginia Tech Carilion School of Medicine, Roanoke, said the results are promising and important because there are so few treatment options for the increasing number of older patients with depression and dementia.
The side-effect profile of the combined treatment is better than that of many pharmacologic treatments, Ratnakaran noted. As more research like this comes out, Ratnakaran predicts that cognitive remediation and tCDS will become more readily available.
“This is telling us that the field of psychiatry, and also dementia, is progressing beyond your usual pharmacotherapy treatments,” said Ratnakaran, who also is chair of the American Psychiatric Association’s Council on Geriatric Psychiatry.
The study received support from the Canada Brain Research Fund of Brain Canada, Health Canada, the Chagnon Family, and the Centre for Addiction and Mental Health Discovery Fund. Mulsant reported holding and receiving support from the Labatt Family Chair in Biology of Depression in Late-Life Adults at the University of Toronto; being a member of the Center for Addiction and Mental Health Board of Trustees; research support from Brain Canada, Canadian Institutes of Health Research, Center for Addiction and Mental Health Foundation, Patient-Centered Outcomes Research Institute, and National Institutes of Health; and nonfinancial support from Capital Solution Design and HappyNeuron. Ratnakaran reported no relevant conflicts.

new research suggests.
The cognitive remediation intervention included a series of progressively difficult computer-based and facilitator-monitored mental exercises designed to sharpen cognitive function.
Researchers found that using cognitive remediation with tDCS slowed decline in executive function and verbal memory more than other cognitive functions. The effect was stronger among people with rMDD versus those with MCI and in those at low genetic risk for Alzheimer’s disease.
“We have developed a novel intervention, combining two interventions that if used separately have a weak effect but together have substantial and clinically meaningful effect of slowing the progression of cognitive decline,” said study author Benoit H. Mulsant, MD, chair of the Department of Psychiatry, University of Toronto, Ontario, Canada, and senior scientist at the Center for Addiction and Mental Health, also in Toronto.
The findings were published online in JAMA Psychiatry.
High-Risk Group
Research shows that older adults with MDD or MCI are at high risk for cognitive decline and dementia. Evidence also suggests that depression in early or mid-life significantly increases the risk for dementia in late life, even if the depression has been in remission for decades.
A potential mechanism underlying this increased risk for dementia could be impaired cortical plasticity, or the ability of the brain to compensate for damage.
The PACt-MD trial included 375 older adults with rMDD, MCI, or both (mean age, 72 years; 62% women) at five academic hospitals in Toronto.
Participants received either cognitive remediation plus tDCS or sham intervention 5 days per week for 8 weeks (acute phase), followed by 5-day “boosters” every 6 months.
tDCS was administered by trained personnel and involved active stimulation for 30 minutes at the beginning of each cognitive remediation group session. The intervention targets the prefrontal cortex, a critical region for cognitive compensation in normal cognitive aging.
The sham group received a weakened version of cognitive remediation, with exercises that did not get progressively more difficult. For the sham stimulation, the current flowed at full intensity for only 54 seconds before and after 30-second ramp-up and ramp-down phases, to create a blinding effect, the authors noted.
A geriatric psychiatrist followed all participants throughout the study, conducting assessments at baseline, month 2, and yearly for 3-7 years (mean follow-up, 48.3 months).

A Finger-Prick Test for Alzheimer’s Disease?
In a pilot study, researchers found a good correlation of p-tau217 levels from blood obtained via standard venous sampling and from a single finger prick.
“We see the potential that capillary p-tau217 from dried blood spots could overcome the limitations of standard venous collection of being invasive, dependent on centrifuges and ultra-low temperature freezers, and also requiring less volume than standard plasma analysis,” said lead investigator Hanna Huber, PhD, Department of Psychiatry and Neurochemistry, Institute of Neuroscience and Physiology, University of Gothenburg, Sweden.
The findings were presented at the 17th Clinical Trials on Alzheimer’s Disease (CTAD) conference.
Strong Link Between Venous and Capillary Samples
p-tau217 has emerged as the most effective blood test to identify Alzheimer’s disease. However, traditional venous blood sampling requires certain infrastructure and immediate processing. Increased and simplified access to this blood biomarker could be crucial for early diagnosis, proper patient management, and prompt initiation of disease-modifying treatments.
The DROP-AD project is investigating the diagnostic performance of finger-prick collection to accurately measure p-tau217. In the current study, the research team obtained paired venous blood and capillary blood samples from 206 adults (mean age, 71.8 years; 59% women), with or without cognitive impairment, from five European centers. A subset of participants provided a second finger-prick sample collected without any supervision.
The capillary blood samples were obtained via a single finger prick, and then single blood drops were applied to a dried plasma spot (DPS) card, which was then shipped to a lab (without temperature control or cooling) for p-tau217 measurement. Cerebrospinal fluid biomarkers were available for a subset of individuals.
Throughout the entire study population, there was a “very convincing correlation” between p-tau217 levels from capillary DPS and venous plasma, Huber told conference attendees.
Additionally, capillary DPS p-tau217 levels were able to discriminate amyloid-positive from amyloid-negative individuals, with levels of this biomarker increasing in a stepwise fashion, “from cognitively unimpaired individuals to individuals with mild cognitive impairment and, finally, to dementia patients,” Huber said.
Of note, capillary p-tau217 levels from DPS samples that were collected by research staff did not differ from unsupervised self-collected samples.
What about the stability of the samples? Capillary DPS p-tau-217 is “stable over 2 weeks at room temperature,” Huber said.
Ready for Prime Time?
Preliminary data from the DROP-AD project highlight the potential of using finger-prick blood collection to identify neurofilament light (NfL) and glial fibrillary acidic protein (GFAP), two other Alzheimer’s disease biomarkers.
“We think that capillary p-tau217, but also other biomarkers, could be a widely accessible and cheap alternative for clinical practice and clinical trials in individuals with cognitive decline if the results are confirmed in longitudinal and home-sampling cohorts,” Huber concluded.
“Measuring biomarkers by a simple finger prick could facilitate regular and autonomous sampling at home, which would be particularly useful in remote and rural settings,” she noted.
The findings in this study confirm and extend earlier findings that the study team reported last year at the Alzheimer’s Association International Conference (AAIC).
“The data shared at CTAD 2024, along with the related material previously presented at AAIC 2023, reporting on a ‘finger prick’ blood test approach is interesting and emerging work but not yet ready for clinical use,” said Rebecca M. Edelmayer, PhD, Alzheimer’s Association vice president of scientific engagement.
“That said, the idea of a highly accessible and scalable tool that can aid in easier and more equitable diagnosis would be welcomed by researchers, clinicians, and individuals and families affected by Alzheimer’s disease and all other dementias,” Edelmayer said.
“This finger-prick blood testing technology for Alzheimer’s biomarkers still has to be validated more broadly, but it is very promising. Advancements in technology and practice demonstrate the simplicity, transportability, and diagnostic value of blood-based biomarkers for Alzheimer’s,” she added.
The Alzheimer’s Association is currently conducting a systematic review of the evidence and preparing clinical practice guidelines on blood-based biomarker tests for specialized healthcare settings, with publications, clinical resources, and tools anticipated in 2025, Edelmayer noted.
The study had no commercial funding. Huber and Edelmayer report no relevant conflicts of interest.

Minor Progress in Gender Pay Equity, But a Big Gap Persists
Despite some recent progress in compensation equity, women in medicine continue to be paid significantly lower salaries than men.
According to the Female Compensation Report 2024 by Medscape, male doctors of any kind earned an average salary of about $400,000, whereas female doctors earned approximately $309,000 — a 29% gap.
The report analyzed survey data from 7000 practicing physicians who were recruited over a 4-month period starting in October 2023. The respondents comprised roughly 60% women representing over 29 specialties.
In the 2022 report, the pay gap between the genders was 32%. But some women in the field argued substantial headway is still needed.
“You can try and pick apart the data, but I’d say we’re not really making progress,” said Susan T. Hingle, MD, an internist in Illinois and president of the American Medical Women’s Association. “A decline by a couple of percentage points is not significantly addressing this pay gap that over a lifetime is huge, can be millions of dollars.”
The gender gap was narrower among female primary care physicians (PCPs) vs medical specialists. Female PCPs earned around $253,000 per year, whereas male PCPs earned about $295,000 per year. Hingle suggested that female PCPs may enjoy more pay equity because health systems have a harder time filling these positions.
On the other hand, the gap for specialists rose from 27% in 2022 to 31% in 2023. Differences in how aggressively women and men negotiate compensation packages may play a role, said Hingle.
“Taking negotiation out of the equation would be progress to me,” said Hingle.
Pay disparity did not appear to be the result of time spent on the job — female doctors reported an average of 49 work hours per week, whereas their male counterparts reported 50 work hours per week.
Meanwhile, the pay gap progressively worsened over time. Among doctors aged 28-34 years, men earned an average of $53,000 more than women. By ages 46-49, men earned an average of $157,000 more than women.
“I had to take my employer to court to get equal compensation, sad as it is to say,” said a hospitalist in North Carolina.
Nearly 60% of women surveyed felt they were not being paid fairly for their efforts, up from less than half reported in Medscape’s 2021 report. Hingle said that this figure may not only reflect sentiments about the compensation gap, but also less support on the job, including fewer physician assistants (PAs), nurses, and administrative staff.
“At my job, I do the work of multiple people,” said a survey respondent. “Junior resident, senior resident, social worker, nurse practitioner, PA — as well as try to be a teacher, researcher, [and] an excellent doctor and have the time to make patients feel as if they are not in a rush.”
Roughly 30% of women physicians said they would not choose to go into medicine again if given the chance compared with 26% of male physicians.
“Gender inequities in our profession have a direct impact,” said Shikha Jain, MD, an oncologist in Chicago and founder of the Women in Medicine nonprofit. “I think women in general don’t feel valued in the care they’re providing.”
Jain cited bullying, harassment, and fewer opportunities for leadership and recognition as factors beyond pay that affect female physicians’ feelings of being valued.

Is This Methadone’s Moment?
Methadone has been shown to be highly effective for opioid use disorder. So why is it still so difficult to prescribe in the United States and is that about to change?
This paper included more than 30,000 patients with opioid use disorder and showed those on methadone were almost 60% significantly less likely to stop treatment at 24 months than their peers assigned to buprenorphine/naloxone (adjusted hazard ratio [aHR], 1.58), with no difference in mortality risk (aHR, 0.57).
“In Canada, unlike the US, methadone and buprenorphine/naloxone are both available in office-based settings. Methadone really outperforms buprenorphine/naloxone in being able to retain people in treatment, which is our main goal and comes with a host of benefits,” Bohdan Nosyk, PhD, with Simon Fraser University in Burnaby, British Columbia, Canada, who worked on the study, said in an interview.
In addition, a recent systematic review and meta-analysis of relevant research involving more than 1 million patients with opioid use disorder also showed better treatment retention with methadone than with buprenorphine.
During the COVID-19 pandemic, relaxed methadone regulations, that included take-home medications, did not lead to an increase in overdoses. Instead, these changes improved treatment retention and patient experiences, highlighting the potential benefits of further deregulation.
‘Atrocious’ Outdated Policies
However, despite methadone’s proven efficacy and safety for opioid use disorder, it remains vastly underutilized because of outdated US policies restricting its use to opioid treatment programs (OTPs).
“It’s absolutely atrocious that methadone policies have not kept up with the evidence. If you look at other countries that have expanded their access to methadone, their overdose rates have fallen dramatically,” said Leslie Suen, MD, with the University of California, San Francisco, and coauthor of a recent JAMA Viewpoint on this topic.
“Methadone is a very good medication that’s been shown over and over to be very effective and safe,” Alan Leshner, PhD, past director of the National Institute on Drug Abuse, said in an interview.
“There is no reason why it couldn’t be administered through pharmacies or through physicians’ offices as long as it’s done in a controlled and careful way,” said Leshner.
Leshner chaired the committee that produced the 2019 report Medications for Opioid Use Disorder Save Lives.
“We learned during COVID that increasing the amount of take-home methadone and increasing access does not lead to an increase in deaths or an increase in overdose, so it’s hard to find a reason not to do it,” he said.
Change Finally on the Horizon?
Several recent and proposed policy changes could revolutionize methadone delivery in the United States.
In March 2022, in response to the pandemic, the Drug Enforcement Administration (DEA) allowed hospitals to dispense up to a 3-day supply of methadone (known as the 72-hour rule) to bridge care transitions without needing OTPs.
In April 2024, the Substance Abuse and Mental Health Services Administration and DEA codified many methadone and buprenorphine delivery flexibilities granted temporarily during the pandemic, including increased use of telehealth assessments and earlier access to take-home methadone doses.
Another contemporary policy change is expansion of the Americans with Disabilities Act mandating that patients taking medications for opioid use disorder, such as methadone, be able to continue treatment when transitioning to settings such as hospitals, jails, and skilled nursing facilities.
At the state level, California Governor Gavin Newsom recently signed a bill, effective immediately, that expands access to methadone treatment in his state.
On the horizon at the federal level is the Modernizing Opioid Treatment Access Act (MOTAA) — the bipartisan and bicameral bill introduced by Sen. Ed Markey (D-MA) and Sen. Rand Paul (R-KY), along with Rep. Donald Norcross (D-NJ) and Rep. Don Bacon, (R-NE) — that would allow methadone to be prescribed by addiction specialists and dispensed in community pharmacies.
An Ethical Imperative
“With only about 2000 OTP clinics clustered in urban areas, less than 25% of people who are diagnosed with opioid use disorder are actually able to access methadone,” Caty Simon, with the National Survivors Union, Greensboro, North Carolina, and coauthor of the JAMA Viewpoint, said in an interview.
While MOTAA represents a major step forward, limiting methadone prescribing to addiction specialists may not fully address the treatment gap, particularly in rural and underserved areas, Simon said.
To optimize methadone’s potential, she’d like to see further expansion of prescribing privileges to general healthcare providers.
“As someone with lived and living experience of opioid use and treatment, and somebody who works nationally and locally in organizations of people impacted by drug use, I know people in my area right now — marginalized people of color — who would have much better chances of survival if they were able to access methadone. If MOTAA passed tomorrow, we could save so many lives. There is an ethical imperative to pass it,” Simon said.
Leshner said he is “always very concerned about access, particularly for underserved populations, poor people, people living in rural areas. If you can access the medications you need, you’re in big trouble.”
Is this methadone’s moment? “I’m a little optimistic, but I haven’t seen the progress I would like to see,” Leshner said.

Methadone has been shown to be highly effective for opioid use disorder. So why is it still so difficult to prescribe in the United States and is that about to change?
This paper included more than 30,000 patients with opioid use disorder and showed those on methadone were almost 60% significantly less likely to stop treatment at 24 months than their peers assigned to buprenorphine/naloxone (adjusted hazard ratio [aHR], 1.58), with no difference in mortality risk (aHR, 0.57).
“In Canada, unlike the US, methadone and buprenorphine/naloxone are both available in office-based settings. Methadone really outperforms buprenorphine/naloxone in being able to retain people in treatment, which is our main goal and comes with a host of benefits,” Bohdan Nosyk, PhD, with Simon Fraser University in Burnaby, British Columbia, Canada, who worked on the study, said in an interview.
In addition, a recent systematic review and meta-analysis of relevant research involving more than 1 million patients with opioid use disorder also showed better treatment retention with methadone than with buprenorphine.
During the COVID-19 pandemic, relaxed methadone regulations, that included take-home medications, did not lead to an increase in overdoses. Instead, these changes improved treatment retention and patient experiences, highlighting the potential benefits of further deregulation.
‘Atrocious’ Outdated Policies
However, despite methadone’s proven efficacy and safety for opioid use disorder, it remains vastly underutilized because of outdated US policies restricting its use to opioid treatment programs (OTPs).
“It’s absolutely atrocious that methadone policies have not kept up with the evidence. If you look at other countries that have expanded their access to methadone, their overdose rates have fallen dramatically,” said Leslie Suen, MD, with the University of California, San Francisco, and coauthor of a recent JAMA Viewpoint on this topic.

FDA Okays Abuse-Deterrent Opioid for Severe Pain
Roxybond, an immediate-release (IR) formulation of oxycodone hydrochloride, is made with Protega’s SentryBond technology, which makes it harder for people to crush, inject, or snort, according to the company.
In a statement from Protega, Paul Howe, the company’s chief commercial officer, said the drug meets an “unmet need for an IR opioid with abuse-deterrent technology that may reduce misuse and abuse while providing pain relief to medically appropriate patients when used as indicated.”
To determine the tablet’s ability to withstand manipulation, more than 2000 in vitro tests were conducted, according to the release. The findings indicate Roxybond reduces — but does not entirely negate — the potential for intranasal and intravenous abuse.
Roxybond was previously approved in 5-, 15-, and 30-mg doses. The 10 mg option provides clinicians with the ability to better modify side effects, manage titration, and provide precision care for patients on opioid therapy, according to Protega.
“For patients, the range of doses can provide better pain control, reduce the risk of side effects, and provide a smoother transition during dosing transitions,” the company stated.
Roxybond is contraindicated in patients with significant respiratory depression, acute or severe bronchial asthma, gastrointestinal obstruction, or hypersensitivity to oxycodone. The drug is not intended for long-term use unless otherwise determined by a clinician. Roxybond also is subject to the FDA’s Risk Evaluation and Mitigation Strategies for opioids.
“The development of Roxybond with SentryBond is a step forward in fighting the national epidemic of prescription opioid overdose,” said Eric Kinzler, PhD, vice president of medical and regulatory affairs for Protega, in a release. “Protega is dedicated to our mission to block the path to abuse and work with healthcare professionals across the continuum of care to reduce misuse and abuse.”
