Some doctors may be scratching their heads over a new analysis reporting that combined calcium and vitamin D (CaD) supplements appear to be associated with a slight 6% increase in cardiovascular (CVD) mortality, a slight 7% decrease in cancer risk, and no effect on osteoporotic fracture in postmenopausal women.

The study, in Annals of Internal Medicine, found no effect of supplementation on all-cause mortality.

The findings emerged from an analysis of more than 20 years’ follow-up data on a randomized trial in postmenopausal women conducted as part of the Women’s Health Initiative (WHI).

Cynthia A. Thomson, PhD, RD, first author and cancer prevention scientist at the Arizona Cancer Center and a professor of health promotion sciences at the University of Arizona in Tucson said the findings recommend individualized assessment of the need for supplements for older women as they consider them in hopes of preventing fractures.

Study Details

The investigators conducted postintervention follow-up of the WHI’s 7-year multicenter randomized intervention trial of CaD vs placebo.

Since existing evidence of long-term health outcomes was limited, the trial, begun in 1999 and closed in 2005, enrolled 36,282 postmenopausal women (mean age 62) with no history of breast or colorectal cancer. They were randomly assigned 1:1 to supplementation with 1000 mg of calcium carbonate (400 mg elemental calcium) plus 400 IU of vitamin D3 daily or placebo, taken twice daily in half doses.

Study outcomes were incidence of CRC, total and invasive breast cancer; disease-specific and all-cause mortality; total CVD; and hip fracture measured through December 2020, with analyses stratified by personal supplement usage.

Cancer. CaD was associated with reduced incident total cancer, CRC, and invasive breast cancer — notably among participants not taking CaD before randomization. Cancer incidence estimates varied widely, the authors noted, when stratified by supplement use before randomization. Noting that CaD seemed to have more cancer-related impact in those without prior supplementation, the authors suggested supplementation may affect cancer biology primarily by augmenting nutrient insufficiency.

An estimated 7% reduction in cancer mortality was observed after a median cumulative follow-up of 22.3 years: 1817 vs 1943 deaths (hazard ratio, 0.93; 95% CI, 0.87-0.99).

CVD. An estimated 6% increase in CVD mortality was seen in the CaD group: 2621 vs 2420 deaths (HR, 1.06; 95% CI, 1.01-1.12). Pretrial supplement users were found to be at higher CVD risk.

Hip fracture. No effect on hip fracture risk was measured, but the authors cautioned that hip fracture and CVD outcomes were available only for a subset of participants, and the effects of calcium alone vs vitamin D alone vs the combination could not be disentangled.

In a small subgroup analysis, some CaD users were seen to respond in terms of bone mineral density but since only 4 of the study’s 40 sites collected such information, the study was underpowered to examine the effect. ”Many other studies, however, show a response to supplementation in women who already have bone mineral deficits,” Dr. Thomson said.
 

The Calcification Question

One of the possible mechanisms of harm is that high-dose calcium supplements can increase the rate of blood coagulation and promote vascular calcification, said Emma Laing, PhD, RD, director of dietetics at the University of Georgia in Athens and a spokesperson for the Chicago-based Academy of Nutrition and Dietetics.

“Other factors that should be considered when determining a patient’s CVD risk are race, genetic predisposition, medical and social history, response to stress, and lifestyle behaviors, as well as the length of time supplements have been consumed,” added Dr. Laing, who was not involved in the WHI analysis.

“We asked ourselves if CaD supplements might contribute to calcification of the coronary arteries, since some believe this to be the case, although the literature is mixed,” said Dr. Thomson.

“So we did a shorter ancillary study in a small sample of several hundred [women] to see if there was any increase in calcification” and no difference was seen on imaging across the two arms. “However, women who were already on supplements before entering the study seemed to be at higher CVD risk,” she said.

Added study coauthor JoAnn E. Manson, MD, DrPH, chief of the division of preventive medicine at Brigham and Women’s Hospital and professor of women’s health at Harvard Medical School, both in Boston: “With no increase or decrease in coronary artery calcium at the end of the trial, we don’t believe starting or continuing calcium/vitamin D supplements should require screening for coronary artery disease.”

Vitamin D Supplementation

As for vitamin D only supplementation, an updated meta-analysis including more than 83,000 individuals showed that it confers no cardiovascular protection and is therefore not indicated for this purpose.
 

Practice Considerations

Offering an outsider’s perspective, Sarah G. Candler, MD, MPH, an internist in Houston specializing in primary care for older high-risk adults, said: “Unfortunately, this latest study continues the trend of creating more questions than answers. If the adverse outcome of CVD death is a result of supplementation, it is unclear if this is due to the vitamin D, the calcium, or both. And it is unclear if this is dose dependent, time dependent, or due to concurrent risk factors unique to certain populations.

Dr. Candler

“It is recommended that patients at risk of osteoporosis based on age, sex, medications, and lifestyle be screened for osteoporosis and treated accordingly, including supplementation with CaD,” Dr. Candler said. “It remains unclear whether supplementation with CaD in the absence of osteoporosis and osteopenia is net beneficial or harmful, and at this time I would not recommend it to my patients.” 

Added Dr. Manson: “The very small increase seen in cardiovascular mortality wouldn’t be a reason to discontinue supplementation among women who have been advised by their healthcare providers to take these supplements for bone health or other purposes.

“Among those at usual risk of fracture, we recommend trying to obtain adequate calcium and vitamin D from food sources first and to use supplements only for the purpose of filling gaps in intake,” Dr. Manson continued. Overall, the findings support the national recommended dietary allowances for daily calcium intake of 1200 mg and daily vitamin D intake of 600-800 IU among postmenopausal women for maintenance of bone health, she said.

While a 2022 study found that vitamin D supplementation alone did not prevent fractures in healthy adults, other research has shown that a calcium/vitamin D combination is more likely to protect the skeleton.

“Patients at risk for fractures will probably benefit from calcium and/or vitamin D supplementation if they do not meet dietary intake requirements, have malabsorption syndromes, are taking medications that affect nutrient absorption, or if they are older and not regularly exposed to sunlight,” said Dr. Laing. “A combination of biochemical, imaging, functional, and dietary intake data can help determine if a supplement is warranted.”

She stressed that additional research is needed in more diverse populations before changing practice guidelines. “However, doctors should continue to weigh the risks and benefits of prescribing supplements for each patient.”

The WHI program is funded by the National Heart, Lung, and Blood Institute. Dr. Thomson disclosed no competing interests. Dr. Manson reported a relationship with Mars Edge. Multiple authors reported grant support from government funding agencies. The outside commentators had no relevant competing interests to disclose.

Jason Black, MD, trained in family medicine, worked for Kaiser Permanente, and subsequently completed a fellowship in geriatrics. Today, he treats frail elderly patients, mostly residents of nursing homes and assisted living facilities or living in their own homes, for Gilchrist, a hospice and palliative care organization serving Baltimore and central Maryland.

“I’m practicing family medicine to the extent that I’m treating the family unit, including the anxieties of the adult children, and finding solutions for the parents,” said Dr. Black, one of Gilchrist’s 62 employed providers, one third of whom are physicians. One of his most important roles is medication reconciliation and deprescribing.

Palliative care, a medical specialty that focuses on clarifying the treatment goals of seriously ill patients, helping with end-of-life planning, and emphasizing pain and symptom management, has been growing in recent years. Already well-established in most US hospitals, it is expanding in community settings, often as an extension of hospice programs.

Now, by adding primary care physicians and practices to their service mix, palliative care groups are better meeting the needs of a neglected — and costly — population of frail elders. In doing so, they also are better able to find a niche in the rapidly evolving alphabet soup of value-based care and its varieties of shared savings for providers who post positive outcomes.

Most patients Dr. Black sees find it difficult to visit their doctors in a clinic setting, although they face a variety of medical needs and chronic conditions of aging. They may have a prognosis of several years to live and, thus, do not qualify for hospice care. To him, a palliative approach offers the satisfaction of focusing on what is most important to patients at this difficult time in their lives, rather than predetermined clinical metrics like blood pressure or blood glucose. “It takes a lot of work, but it feels important and rewarding,” he said.

A recent survey of community-dwelling older adults in Ontario, Canada, found most patients fail to receive this treatment homes in the final 3 months of life.
 

Continuums of Patients and Models

Gilchrist started as a nonprofit, hospital-affiliated hospice program in 1994 and in 2000 took on the management of a geriatric medicine practice for its parent, Greater Baltimore Medical Center. Today, its physicians and nurse practitioners see a range of patients in geriatric primary care, palliative medicine, and hospice, according to its chief medical officer, Mark J. Gloth, DO.

“As people progress in their disease, their location — where they call home — may change as well,” Dr. Gloth said. “We offer a continuum of care in order to not lose people through those transitions. That’s the core of our mission — making sure we are there to escort people through the difficult moments in their lives.”

Models for value-based care encompass accountable care organizations (ACOs), including the ACO REACH (Realizing Equity, Access, and Community Health) high-needs model for traditional Medicare patients, and Medicare Shared Savings Programs for fee-for-service beneficiaries. These value-based models offer a variety of opportunities for the palliative care organization to share in savings resulting from keeping the patient out of the hospital or emergency room and other quality and cost benchmarks.
 

Coming Together to Meet Needs

Gilchrist is one of nine hospice and palliative organizations that have joined to form their own multistate ACO, Responsive Care Solutions, focused on the clinical needs of frail elderly Medicare beneficiaries. Hospice of the Valley in Phoenix has Geriatric Solutions, a frail elder physician practice. And Capital Caring Health, a hospice and palliative care agency serving metro Washington, DC, has deployed several physicians and nurse practitioners on the road doing primary care at home, said Heidi Young, MD, its Primary Care at Home Lead Physician.

“Five years ago, we started our primary care practice under the umbrella of a 40-year-old hospice organization because we thought we needed to prepare for the changes that are coming to the hospice model,” Dr. Young said. “The thought was that we’re not just a hospice organization; we’re an advanced illness organization. We will come to your home, whatever that is, and provide your primary care.”

The greatest potential gains for a hospice organization are from assuming 100% risk for a large population of patients, keeping them out of the hospital to lower the costs of their care, then reaping those gains under a value-based profit-sharing model, Dr. Young said.

“Our program is still new and working toward getting more patients aligned into value-based models,” she said. “It’s a work in progress.”
 

A Foot in Each World

Agencies like Capital Caring and Gilchrist derive the largest share of their physician income from billing Medicare Part B and other insurers per visit. But that billing is not enough to break even on physician services.

With hopes for a value-based future, Gilchrist also gets grants from elder-facing charitable foundations to cover up to 40% of the costs of its home-based primary care, according to its president, Catherine Hamel. Hospice care continues to be paid on a per-diem basis by Medicare for eligible terminally ill patients, including Medicare Advantage patients, although the Centers for Medicare & Medicaid Services is reportedly considering new models for the hospice benefit.

The National Partnership for Healthcare and Hospice Innovation (NPHI) is a trade group representing more than 100 nonprofit, hospice-based organizations participating in palliative care and value-based care.

For a hospice to be successful in the evolving post–acute care/end-of-life care landscape, it can no longer rely solely on its hospice line of business, no matter how high-quality, said Ethan McChesney, policy director for the Washington, DC-based nonprofit.

NPHI members have developed their own palliative care programs, and perhaps, a quarter have primary care at home practices, Mr. McChesney said. Some of them acquired existing primary care practices in their service area with which they already had relationships; others created their own.

For hospice organizations building a continuum of services for the seriously ill, adding a primary care at home practice is a natural fit, he said. “You can provide all the services you would as a traditional primary care practice while you have the opportunity to establish long-term relationships with patients and their caregivers that lend themselves to palliative care referrals and then hospice referrals downstream [when the patient becomes eligible for hospice care].” Often, this primary medical care is a mix of in-person and telehealth.

Cameron Muir, MD, NPHI’s chief innovation officer, noted that the hamster wheel for primary care doctors has been spinning faster and faster, with reimbursement going down and costs going up.

But with home-based primary care for frail elders under value-based models, Dr. Muir said, the clinician is paid not for making more visits but for taking great care of the patient: “And I’m actually saving Medicare money and getting credit for the hospitalizations that were avoided.”

Jason Black, MD, trained in family medicine, worked for Kaiser Permanente, and subsequently completed a fellowship in geriatrics. Today, he treats frail elderly patients, mostly residents of nursing homes and assisted living facilities or living in their own homes, for Gilchrist, a hospice and palliative care organization serving Baltimore and central Maryland.

“I’m practicing family medicine to the extent that I’m treating the family unit, including the anxieties of the adult children, and finding solutions for the parents,” said Dr. Black, one of Gilchrist’s 62 employed providers, one third of whom are physicians. One of his most important roles is medication reconciliation and deprescribing.

Palliative care, a medical specialty that focuses on clarifying the treatment goals of seriously ill patients, helping with end-of-life planning, and emphasizing pain and symptom management, has been growing in recent years. Already well-established in most US hospitals, it is expanding in community settings, often as an extension of hospice programs.

Now, by adding primary care physicians and practices to their service mix, palliative care groups are better meeting the needs of a neglected — and costly — population of frail elders. In doing so, they also are better able to find a niche in the rapidly evolving alphabet soup of value-based care and its varieties of shared savings for providers who post positive outcomes.

Most patients Dr. Black sees find it difficult to visit their doctors in a clinic setting, although they face a variety of medical needs and chronic conditions of aging. They may have a prognosis of several years to live and, thus, do not qualify for hospice care. To him, a palliative approach offers the satisfaction of focusing on what is most important to patients at this difficult time in their lives, rather than predetermined clinical metrics like blood pressure or blood glucose. “It takes a lot of work, but it feels important and rewarding,” he said.

A recent survey of community-dwelling older adults in Ontario, Canada, found most patients fail to receive this treatment homes in the final 3 months of life.
 

Continuums of Patients and Models

Gilchrist started as a nonprofit, hospital-affiliated hospice program in 1994 and in 2000 took on the management of a geriatric medicine practice for its parent, Greater Baltimore Medical Center. Today, its physicians and nurse practitioners see a range of patients in geriatric primary care, palliative medicine, and hospice, according to its chief medical officer, Mark J. Gloth, DO.

“As people progress in their disease, their location — where they call home — may change as well,” Dr. Gloth said. “We offer a continuum of care in order to not lose people through those transitions. That’s the core of our mission — making sure we are there to escort people through the difficult moments in their lives.”

Models for value-based care encompass accountable care organizations (ACOs), including the ACO REACH (Realizing Equity, Access, and Community Health) high-needs model for traditional Medicare patients, and Medicare Shared Savings Programs for fee-for-service beneficiaries. These value-based models offer a variety of opportunities for the palliative care organization to share in savings resulting from keeping the patient out of the hospital or emergency room and other quality and cost benchmarks.
 

Coming Together to Meet Needs

Gilchrist is one of nine hospice and palliative organizations that have joined to form their own multistate ACO, Responsive Care Solutions, focused on the clinical needs of frail elderly Medicare beneficiaries. Hospice of the Valley in Phoenix has Geriatric Solutions, a frail elder physician practice. And Capital Caring Health, a hospice and palliative care agency serving metro Washington, DC, has deployed several physicians and nurse practitioners on the road doing primary care at home, said Heidi Young, MD, its Primary Care at Home Lead Physician.

“Five years ago, we started our primary care practice under the umbrella of a 40-year-old hospice organization because we thought we needed to prepare for the changes that are coming to the hospice model,” Dr. Young said. “The thought was that we’re not just a hospice organization; we’re an advanced illness organization. We will come to your home, whatever that is, and provide your primary care.”

The greatest potential gains for a hospice organization are from assuming 100% risk for a large population of patients, keeping them out of the hospital to lower the costs of their care, then reaping those gains under a value-based profit-sharing model, Dr. Young said.

“Our program is still new and working toward getting more patients aligned into value-based models,” she said. “It’s a work in progress.”
 

A Foot in Each World

Agencies like Capital Caring and Gilchrist derive the largest share of their physician income from billing Medicare Part B and other insurers per visit. But that billing is not enough to break even on physician services.

With hopes for a value-based future, Gilchrist also gets grants from elder-facing charitable foundations to cover up to 40% of the costs of its home-based primary care, according to its president, Catherine Hamel. Hospice care continues to be paid on a per-diem basis by Medicare for eligible terminally ill patients, including Medicare Advantage patients, although the Centers for Medicare & Medicaid Services is reportedly considering new models for the hospice benefit.

The National Partnership for Healthcare and Hospice Innovation (NPHI) is a trade group representing more than 100 nonprofit, hospice-based organizations participating in palliative care and value-based care.

For a hospice to be successful in the evolving post–acute care/end-of-life care landscape, it can no longer rely solely on its hospice line of business, no matter how high-quality, said Ethan McChesney, policy director for the Washington, DC-based nonprofit.

NPHI members have developed their own palliative care programs, and perhaps, a quarter have primary care at home practices, Mr. McChesney said. Some of them acquired existing primary care practices in their service area with which they already had relationships; others created their own.

For hospice organizations building a continuum of services for the seriously ill, adding a primary care at home practice is a natural fit, he said. “You can provide all the services you would as a traditional primary care practice while you have the opportunity to establish long-term relationships with patients and their caregivers that lend themselves to palliative care referrals and then hospice referrals downstream [when the patient becomes eligible for hospice care].” Often, this primary medical care is a mix of in-person and telehealth.

Cameron Muir, MD, NPHI’s chief innovation officer, noted that the hamster wheel for primary care doctors has been spinning faster and faster, with reimbursement going down and costs going up.

But with home-based primary care for frail elders under value-based models, Dr. Muir said, the clinician is paid not for making more visits but for taking great care of the patient: “And I’m actually saving Medicare money and getting credit for the hospitalizations that were avoided.”

TOPLINE:

Treatment modifications, such as dose reductions, schedule changes, or use of less toxic regimens, can improve how well older patients with advanced cancer and aging-related conditions tolerate chemotherapy regimens.

METHODOLOGY:

• Older patients are underrepresented in clinical trials, which means the reported risks associated with standard-of-care regimens typically reflect outcomes in younger, healthier patients. This underrepresentation in clinical trials has also led to uncertainties about the safety of standard chemotherapy regimens in older patients who often have other health conditions to manage, alongside cancer.
• In this secondary analysis, researchers evaluated the association between primary treatment modifications to standard-of-care chemotherapy regimens and treatment tolerability.
• The trial included 609 patients aged ≥ 70 years who had advanced cancer alongside at least one age-related condition, such as impaired cognition, and planned to start a new palliative chemotherapy regimen in the community oncology setting. The most common cancer types were gastrointestinal cancer (37.4%) and lung cancer (28.6%).
• The primary outcome was grade 3-5 adverse events within 3 months of chemotherapy initiation.
• Secondary outcomes included patient-reported functional decline and combined adverse outcomes, which incorporated clinician-rated toxic effects, patient-reported functional decline, and 6-month overall survival.

TAKEAWAY: 

• Overall, 281 patients (46.1%) received a primary treatment modification, most often a dose reduction (71.9%) or a scheduling change (11.7%).
• Patients who received primary treatment modifications had a 15% lower risk for grades 3-5 adverse effects (relative risk [RR], 0.85) and a 20% lower risk for patient-reported functional decline (RR, 0.80) than those who received standard treatment.
• Patients receiving treatment modifications had 32% lower risk for a worse combined adverse outcome (odds ratio, 0.68).
• Cancer type may matter as well. When looking at outcomes by cancer type, patients with gastrointestinal cancers who received a primary treatment modification had a lower risk for toxic effects (RR, 0.82), whereas patients with lung cancer did not (RR, 1.03; 95% CI, 0.88-1.20).

IN PRACTICE:

These findings “can help oncologists to choose the optimal drug regimen, select a safe and effective initial dose, and undertake appropriate monitoring strategies to manage the clinical care of older people with advanced cancer,” the authors said.

TOPLINE:

In a long-term nationwide cohort study from Norway, older age and male sex were associated with an increased risk for a second primary invasive melanoma.

METHODOLOGY:

• Knowledge about one’s risk for a second primary invasive melanoma over time remains incomplete.
• Using data from the Cancer Registry of Norway, researchers performed a cohort study of 19,196 individuals diagnosed with invasive melanomas during 2008-2020; 51% were women. The mean age at the first primary melanoma diagnosis was 62 years.
• The main outcome of interest was the incidence rate of second primary invasive melanoma after the first diagnosis.
• The researchers used accelerated failure time models to examine potential associations with patient and tumor characteristics. They also calculated the median time between first and second melanomas and the likelihood of second primary melanomas on the same or different site as the first primary melanoma.

TAKEAWAY: 

• The incidence rate of a second primary melanoma in the year following a first primary melanoma was 16.8 (95% CI, 14.9-18.7) per 1000 person-years. This decreased to 7.3 (95% CI, 6.0-8.6) per 1000 person-years during the second year and remained stable after that.
• Patient age influenced the median time between first and second primaries. The median interval was 37 months (95% CI, 8-49) in patients aged < 40 years, 18 months (95% CI, 13-24) in patients aged 50-59 years, and 11 months (95% CI, 7-18) in patients aged ≥ 80 years.
• The body site of the second primary melanoma was the same as the first primary in 47% of patients but was located on a different body site in the remaining 53% of patients.
• Among patients who developed a second primary melanoma on the same site as the first, the median interval was shorter for men compared with women: A median of 12 (95% CI, 7-19) months vs 22 (95% CI, 11-35) months, respectively.

IN PRACTICE:

“Our findings suggest that increased surveillance may be considered for older patients, especially men, for at least the first 3 years after their initial diagnosis, regardless of the characteristics of their first melanoma,” the authors wrote.

A prognostic tool may facilitate the early identification of older adults in the community who would benefit from palliative care in their final years, new research from Canada suggested.

The analysis of data from close to a quarter million community-dwelling older adults in Ontario with at least one interRAI (Resident Assessment Instrument) home care assessment showed that only half of those with an estimated survival of fewer than 3 months received at least one palliative home care visit before death.

“One of the challenges and a barrier to accessing palliative home care is the difficulty of predicting survival,” Amy Hsu, PhD, an investigator at the Bruyère Research Institute in Ottawa, Ontario, Canada, told this news organization. “Clinicians are good at prognosticating when a patient might be entering their last 3-6 weeks of life, but they have a harder time predicting if someone will survive 6 months or longer.”

The team developed the Risk Evaluation for Support: Predictions for Elder-life in their Communities Tool (RESPECT) to see whether access to predicted survival data could inform conversations about a patient’s status and palliative care needs.

The study was published online in the Canadian Medical Association Journal.
 

Setting Care Goals

Researchers analyzed population health administrative data from Ontario involving home care clients who received at least one interRAI Home Care assessment between April 2018 and September 2019. The cohort included 247,377 adults (62% women) with a mean age of 80.1 years at the time of assessment. Comorbidities, including congestive heart failure, coronary artery disease, cancer, and chronic obstructive pulmonary disease, as well as symptoms of health instability, were more prevalent among those at higher risk of dying.

The team used an updated, validated version of RESPECT to predict survival.

Only 2.6% of home care clients had received a clinician diagnosis of an end-stage disease, which was more prevalent among those at highest mortality risk (77.9%). Most clients (74.5%) required extensive assistance in performing instrumental activities of daily living (ADLs, score ≤ 4), and half (50.3%) were less able to perform ADLs in the last 3 months of life.

Within the cohort, 75% of patients with a predicted median survival of fewer than 3 months, 55.4% of those with a predicted median survival between 3 and 6 months, and 40.7% of those with a predicted median survival between 6 and 12 months died within 6 months of the home care assessment.

Among decedents, 50.6% of those with a RESPECT-estimated median survival of fewer than 3 months received at least one nonphysician palliative home care visit before death. Less than a third (27.8%) received at least one palliative home care visit from a physician.

The proportion of those who received at least one nonphysician visit fell to 38.7% among those with a median survival of between 3 and 6 months and to 29.5% among those with a median survival of between 6 and 12 months.

Patients who received at least one palliative home care visit (from either physicians or nonphysician home care providers) within 6 months of an assessment had clinical characteristics similar to those who did not receive a visit. However, those who did not receive palliative home care were more likely to not have been identified by a clinician as being in their past 6 months of life.

“These results reinforce the role of clinicians in identifying older adults who may be in their last 6 months of life as an important component for the receipt of palliative home care and highlight the value of RESPECT in supplementing clinicians’ assessments of prognosis,” the authors wrote.

“Our goal is to use data and tools like RESPECT to help individuals living with a life-limiting illness have conversations about what their end-of-life care goals and wishes may be and discuss whether a referral to palliative care is appropriate or needed,” Dr. Hsu added. “Data about life expectancy could be helpful for framing these conversations.”

The researchers are working with partners in home, community care, and long-term care to implement RESPECT in their settings.
 

‘Valuable Tool’

Guohua Li, MD, DrPH, professor of epidemiology and anesthesiology at Columbia University Mailman School of Public Health and Vagelos College of Physicians and Surgeons in New York City, commented on the findings for this news organization. He noted that the study is “rigorously designed and meticulously analyzed. The findings are of high validity and population health significance.”

The findings are comparable with what is seen in the United States and Canada, he said, where about 50% of terminally ill patients die at home or in hospice. However, palliative care outside of North America “varies greatly, and in many developing countries, [it] is still in its infancy.”

As a mortality risk prediction algorithm, “RESPECT seems to perform reasonably well,” he said. “If incorporated into the electronic health record, it could be a valuable tool for clinicians to identify patients with less than 6 months of life expectancy and deliver palliative care to these patients. RESPECT appears to be particularly beneficial for home care patients without a clinically diagnosed terminal disease.”

That said, he added, “RESPECT should be viewed as a clinical decision support tool. It is no substitute for clinicians or clinical judgment. Based on the data presented in the paper, the algorithm tends to overestimate the short-term mortality risk for home care patients, therefore resulting in many false alarms.”

The study was supported by the Canadian Institutes of Health Research and the Associated Medical Services. Dr. Hsu is an executive lead on the steering committee of the Ontario Centres for Learning, Research, and Innovation in Long-Term Care. Funding for the centers comes from the Ontario Ministry of Health and Ministry of Long-Term Care and is partially administered by the Bruyère Research Institute. Dr. Li reported no relevant financial interests.

As a mortality risk prediction algorithm, “RESPECT seems to perform reasonably well,” he said. “If incorporated into the electronic health record, it could be a valuable tool for clinicians to identify patients with less than 6 months of life expectancy and deliver palliative care to these patients. RESPECT appears to be particularly beneficial for home care patients without a clinically diagnosed terminal disease.”

That said, he added, “RESPECT should be viewed as a clinical decision support tool. It is no substitute for clinicians or clinical judgment. Based on the data presented in the paper, the algorithm tends to overestimate the short-term mortality risk for home care patients, therefore resulting in many false alarms.”

The study was supported by the Canadian Institutes of Health Research and the Associated Medical Services. Dr. Hsu is an executive lead on the steering committee of the Ontario Centres for Learning, Research, and Innovation in Long-Term Care.

A prognostic tool may facilitate the early identification of older adults in the community who would benefit from palliative care in their final years, new research from Canada suggested.

The analysis of data from close to a quarter million community-dwelling older adults in Ontario with at least one interRAI (Resident Assessment Instrument) home care assessment showed that only half of those with an estimated survival of fewer than 3 months received at least one palliative home care visit before death.

“One of the challenges and a barrier to accessing palliative home care is the difficulty of predicting survival,” Amy Hsu, PhD, an investigator at the Bruyère Research Institute in Ottawa, Ontario, Canada, told this news organization. “Clinicians are good at prognosticating when a patient might be entering their last 3-6 weeks of life, but they have a harder time predicting if someone will survive 6 months or longer.”

The team developed the Risk Evaluation for Support: Predictions for Elder-life in their Communities Tool (RESPECT) to see whether access to predicted survival data could inform conversations about a patient’s status and palliative care needs.

The study was published online in the Canadian Medical Association Journal.
 

Setting Care Goals

Researchers analyzed population health administrative data from Ontario involving home care clients who received at least one interRAI Home Care assessment between April 2018 and September 2019. The cohort included 247,377 adults (62% women) with a mean age of 80.1 years at the time of assessment. Comorbidities, including congestive heart failure, coronary artery disease, cancer, and chronic obstructive pulmonary disease, as well as symptoms of health instability, were more prevalent among those at higher risk of dying.

The team used an updated, validated version of RESPECT to predict survival.

Only 2.6% of home care clients had received a clinician diagnosis of an end-stage disease, which was more prevalent among those at highest mortality risk (77.9%). Most clients (74.5%) required extensive assistance in performing instrumental activities of daily living (ADLs, score ≤ 4), and half (50.3%) were less able to perform ADLs in the last 3 months of life.

Within the cohort, 75% of patients with a predicted median survival of fewer than 3 months, 55.4% of those with a predicted median survival between 3 and 6 months, and 40.7% of those with a predicted median survival between 6 and 12 months died within 6 months of the home care assessment.

Among decedents, 50.6% of those with a RESPECT-estimated median survival of fewer than 3 months received at least one nonphysician palliative home care visit before death. Less than a third (27.8%) received at least one palliative home care visit from a physician.

The proportion of those who received at least one nonphysician visit fell to 38.7% among those with a median survival of between 3 and 6 months and to 29.5% among those with a median survival of between 6 and 12 months.

Patients who received at least one palliative home care visit (from either physicians or nonphysician home care providers) within 6 months of an assessment had clinical characteristics similar to those who did not receive a visit. However, those who did not receive palliative home care were more likely to not have been identified by a clinician as being in their past 6 months of life.

“These results reinforce the role of clinicians in identifying older adults who may be in their last 6 months of life as an important component for the receipt of palliative home care and highlight the value of RESPECT in supplementing clinicians’ assessments of prognosis,” the authors wrote.

“Our goal is to use data and tools like RESPECT to help individuals living with a life-limiting illness have conversations about what their end-of-life care goals and wishes may be and discuss whether a referral to palliative care is appropriate or needed,” Dr. Hsu added. “Data about life expectancy could be helpful for framing these conversations.”

The researchers are working with partners in home, community care, and long-term care to implement RESPECT in their settings.

Long-term adherence to a plant-based diet was not tied to a greater risk of hip fracture and some plant-based regimens may actually reduce the risk, a large cohort study of postmenopausal women in the United States suggested.

Not all plant-centered regimens are healthful, however, and this study factored dietary quality into risk.

Writing in JAMA Network Open, the study authors compared the lowest to highest quintiles of Plant-Based Diet Index scores. They found the most recent intake of a healthy plant-based diet (hPDI) to be associated with a somewhat lower (21%) risk of fracture while the most recent intake of its unhealthy counterpart (uPDI) was linked to a somewhat higher (28%) risk.

“In addition, higher baseline scores in the uPDI were associated with higher risk of hip fracture,” wrote the researchers, led by Mercedes Sotos Prieto, PhD, a nutritional epidemiologist in the Department of Preventive Medicine and Public Health at the Autonomous University of Madrid.

Plant-based diets, characterized by higher consumption of plant foods and lower or no intake of animal foods, have raised concerns about their potential harm to bone health. In a recent meta-analysis, vegetarians, but particularly vegans with no consumption of any animal food, had a higher fracture risk and lower bone mineral density compared with omnivores.

Another study found that compared with meat eaters, fish eaters and vegetarians had a higher risk of hip fractures. These analyses, however, did not assess the quality of the plant-based diets.

“We hypothesized that the differences in the quality of the plant-based diets — whole grains, fruits, and vegetables vs refined carbohydrates or snacks, which are both plant-based but very different, would be important in the association for the risk of hip fracture,” Dr. Sotos Prieto said in an interview.
 

Study details

Her study drew on data from 70,285 postmenopausal White women who were in the US Nurses’ Health Study from 1984 through 2014; data were analyzed from Jan. 1 to July 31, 2023.

The mean age of the nurses was 54.92 years, and 2038 cases of hip fracture were reported during the study over as long as 30 years of follow-up.

Healthy plant foods included whole grains, fruits, vegetables, nuts, legumes, vegetable oils, and tea or coffee and received positive scores, whereas less healthy plant foods such as fruit juices, sweetened beverages, refined grains, potatoes, sweets, or desserts and animal foods received reversed scores. Dietary and lifestyle information was collected by self-reported questionnaires.

Individuals with higher hPDI scores were leaner, more physically active, less likely to be smokers, and more likely to use vitamin and calcium supplements. Not surprisingly, they also had higher intakes of dietary calcium and healthy plant foods and had lower intake of less healthy plant foods. “It’s plausible that reverse causation may account for the risk associations, as individuals with underlying health conditions that predisposed them to higher fracture risk may have changed their diet,” Dr. Sotos Prieto said. “In addition, baseline diet may reflect diet early on, which could be an important predictor of bone mineral density when there was more active bone turnover.”

Lack of information precluded adjustment for the use of anti-osteoporotic medication.

Neither the hPDI, with a hazard ratio (HR) for highest vs lowest quintile of 0.97 (95% confidence interval, 0.83-1.14) nor the uPDI, with an HR for highest vs lowest quintile of 1.02 (95% CI, 0.87-1.20) for diet adherence over the long term was associated with hip fracture risk.

For recent dietary intake in the highest vs lowest quintiles, however, the hPDI was associated with a 21% lower risk of hip fracture: HR, 0.79 (95% CI, 0.68-0.92; P = .02 for trend). In contrast, the uPDI was associated with a 28% higher risk: HR, 1.28 (95% CI, 1.09-1.51; P = .008 for trend).

Future studies in other populations are needed to confirm the results and enhance their generalizability, Dr. Sotos Prieto said. “Investigating the temporal dynamics of dietary patterns and their effects by examining how recent dietary changes may impact health outcomes over different timeframes is important.” In the meantime, people wishing to follow a plant-based diet should make sure it features high-quality foods.

Bariatric surgery is associated with long-term improvements in cognition and brain structure in addition to general health benefits and expected weight loss, a large study found.

Among 133 adults with severe obesity who underwent bariatric surgery, roughly two in five showed > 20% improvement in global cognitive function at 24 months following the surgery. 

“Notably, the temporal cortex exhibited not only higher cortical thickness but also higher vascular efficiency after surgery,” reported Amanda Kiliaan, PhD, Radboud University Medical Center, Nijmegen, the Netherlands, and colleagues.

“These results highlight beneficial vascular responses occurring in conjunction with bariatric surgery,” the researchers wrote. 

They also suggested that weight-loss surgery may represent a treatment option for patients with obesity and dementia. 

The study was published online on February 9, 2024, in JAMA Network Open.

Obesity is associated with an increased risk of developing dementia. Bariatric surgery-induced weight loss has been associated with improvements in brain function and structure in some small cohort studies with short follow-up periods. However, long-term neurological outcomes associated with bariatric surgery are unclear. 

To investigate, Dr. Kiliaan and colleagues studied 133 adults with severe obesity (mean age, 46 years; 84% women) who underwent Roux-en-Y gastric bypass. The researchers collected relevant data from laboratory tests, cognitive tests, and MRI brain scans before surgery and at 6 and 24 months after surgery.

Overall, mean body weight, body mass index, waist circumference, and blood pressure were significantly lower at 6 and 24 months after surgery. At 24 months, significantly fewer patients were taking antihypertensive medication (17% vs 36% before surgery). 

Improvements in inflammatory markers, depressive symptoms, and physical activity were also evident after surgery. 
 

Cognitive Improvements 

Several cognitive domains showed significant improvement at 6 and 24 months after bariatric surgery. Based on the 20% change index, improvements in working memory, episodic memory, and verbal fluency were seen in 11%, 32%, and 24% of participants, respectively. 

Forty percent of patients showed improvement in their able to shift their attention, and 43% showed improvements in global cognition after surgery. 

Several changes in brain parameters were also noted. Despite lower cerebral blood flow (CBF) in several regions, volumes of hippocampus, nucleus accumbens, frontal cortex, white matter, and white matter hyperintensity remained stable after surgery. 

The temporal cortex showed a greater thickness (mean, 2.724 mm vs 2.761 mm; P = .007) and lower spatial coefficient of variation (sCOV; median, 4.41% vs 3.97%; P = .02) after surgery. 

Overall, the results suggest that cognitive improvements “begin shortly after bariatric surgery and are long lasting,” the authors wrote. 

Various factors may be involved including remission of comorbidities, higher physical activity, lower depressive symptoms, and lower inflammatory factors, they suggest. Stabilization of volume, CBF, and sCOV in brain regions, coupled with gains in cortical thickness and vascular efficiency in the temporal cortex could also play a role.
 

‘Remarkable’ Results

“Taken together, the research intimates bariatric surgery’s potential protective effects against dementia manifest through both weight-related brain changes and reducing cardiovascular risk factors,” Shaheen Lakhan, MD, a neurologist and researcher based in Miami, who wasn’t involved in the study, told this news organization.

“These remarkable neurological transformations intimate this surgery represents a pivotal opportunity to combat the parallel public health crises of obesity and dementia threatening society,” he said. 

“In demonstrating a durable cognitive and brain boost out years beyond surgery, patients now have an emphatic answer — these aren’t short-lived benefits but rather profound improvements propelling them positively for the rest of life,” he added. 

This opens up questions on whether the new class of obesity medications targeting glucagon-like peptide 1 (GLP-1) and gastric inhibitory polypeptide pathways, that can achieve weight loss approaching that of bariatric surgery, could have similar benefits. 

The use of GLP-1 drugs have also shown neuroprotective effects such as improvement in motor and cognitive deficits, reduction of neuroinflammation, prevention of neuronal loss, and possibly slowing of neurodegeneration across animal models of Parkinson’s disease, Alzheimer’s disease, and stroke, said Dr. Lakhan. However, the exact mechanisms and ability to cross the blood-brain barrier require further confirmation, especially in humans.

Large, long-term, randomized controlled trials looking into potential effects of semaglutide on early Alzheimer›s disease, including the EVOKE Plus trial, are currently underway, he noted. 

“These game-changing obesity drugs may hand us medicine’s holy grail — a pill to rival surgery’s brain benefits without the scalpel, allowing patients a more accessible path to protecting their brain,” Dr. Lakhan said.

The study had no funding from industry. Dr. Kiliaan and Dr. Lakhan had no relevant disclosures.

“In demonstrating a durable cognitive and brain boost out years beyond surgery, patients now have an emphatic answer — these aren’t short-lived benefits but rather profound improvements propelling them positively for the rest of life,” he added. 

This opens up questions on whether the new class of obesity medications targeting glucagon-like peptide 1 (GLP-1) and gastric inhibitory polypeptide pathways, that can achieve weight loss approaching that of bariatric surgery, could have similar benefits. 

The use of GLP-1 drugs have also shown neuroprotective effects such as improvement in motor and cognitive deficits, reduction of neuroinflammation, prevention of neuronal loss, and possibly slowing of neurodegeneration across animal models of Parkinson’s disease, Alzheimer’s disease, and stroke, said Dr. Lakhan. However, the exact mechanisms and ability to cross the blood-brain barrier require further confirmation, especially in humans.

Large, long-term, randomized controlled trials looking into potential effects of semaglutide on early Alzheimer›s disease, including the EVOKE Plus trial, are currently underway, he noted. 

“These game-changing obesity drugs may hand us medicine’s holy grail — a pill to rival surgery’s brain benefits without the scalpel, allowing patients a more accessible path to protecting their brain,” Dr. Lakhan said.

The study had no funding from industry. Dr. Kiliaan and Dr. Lakhan had no relevant disclosures.

About one-quarter of all adult day services center (ADSC) participants have dementia, and the prevalence of dementia in ADSCs that specialize in the disorder is more than 40%, a new US National Health Statistics Report revealed.

ADSCs are a growing sector of the US home- and community-based long-term care delivery system, providing daytime services to adults with disabilities who often have multiple chronic conditions, including various types of dementia, according to report authors Priyanka Singha, MPH, and colleagues at the US Department of Health and Human Services, Centers for Disease Control and Prevention, National Center for Health Statistics in Bethesda, Maryland.

Dementia often leads to the transition to receiving long-term care services, such as nursing home care. Delaying institutionalization is a primary goal of ADSCs, so they also try to meet the needs of a growing population of community-dwelling adults with dementia.

Survey responses from 1800 ADSCs across the United States showed that overall, 42.2% of participants had dementia in ADSCs specializing in dementia care, while 22.7% of participants in nonspecialized ADSCs also had dementia.

Dementia was more prevalent in the Midwest and West, where nearly one half of participants in specialized centers had dementia.

Nevertheless, the overall prevalence of dementia in ADSCs was similar across US regions, with a slightly lower percentage in the West.
 

Positive Outcomes

The new report used data from the ADSC component of the 2020 National Post-acute and Long-term Care Study collected from January 2020 through mid-July 2021. About 1800 ADSCs from a census of 5500 ADSCs were included and weighted to be nationally representative.

The authors compared dementia prevalence among participants in ADSCs that provide specialized care for dementia with other ADSCs by census region, metropolitan statistical area (MSA) status, chain affiliation, and ownership type.

MSA is a core urban area population of 50,000 or more. ADSCs that specialize in dementia care have specially trained staff, activities, and facilities. They offer social activities, including art and music therapy, dementia-appropriate games, and group exercises, as well as respite care for unpaid caregivers. The survey found that 14% of ADSCs reported specializing in dementia.

The investigators also found that the percentage of ADSC participants with dementia, regardless of center specialization, was higher in the Midwest (32.1%), Northeast (28.5%), and South (24.5%) than in the West (21.1%).

The percentage of participants with dementia in specialized centers was higher in the Midwest (49.5%) and West (48.8%) than in the Northeast (31.9%) and in nonchain centers (50.5%) than in chain-affiliated centers (30.4%).

In addition, the percentage of participants with dementia, regardless of specialization, was higher in nonchain ADSCs (25%) than in chain-affiliated centers (20.1%). In addition, the percentage of participants with dementia in nonspecialized centers was higher in nonchain centers (25%) than in chain-affiliated centers (20.1%).

Finally, the research revealed that the percentage of participants with dementia, regardless of specialization, was higher in nonprofit ADSCs (28.7%) than for-profit centers (21%).

“These findings indicate that ADSCs in MSAs, nonprofit organizations, and nonchain centers provide services to a higher proportion of participants with dementia, particularly among centers that specialize in dementia care,” the investigators wrote.

Whereas “caregivers manage prescription medications, help with activities of daily living, and offer nutritional diets, exercise, and social engagement, ADSCs play a role in providing this type of care for people with dementia while also offering respite for their unpaid caregivers,” they noted.

Overall, they concluded that ADSCs provide positive outcomes for both family caregivers and people with dementia.

They noted that the study’s limitations include the use of cross-sectional data, which cannot show effectiveness for participants receiving care in specialized centers or be used to analyze relationships between other participant-level sociodemographic or health characteristics and specialized dementia care.

Dupuytren contracture can be treated with three invasive methods, but new data from a randomized controlled trial show better 2-year success rates for surgery than for needle fasciotomy and collagenase injection, despite retreatments.

The common hereditary disorder affects the palmar fascia in middle-aged and older people, more often men. The disease typically affects the ring and little fingers and they may curl toward the palm. The disease can’t be cured, but can be eased.

Findings of the study, led by Mikko Petteri Räisänen, MD, with the Department of Orthopedics, Traumatology and Hand Surgery, Kuopio University Hospital, Kuopio, and Tampere University, Tampere, both in Finland, were published online in Annals of Internal Medicine.
 

Initially, Outcomes Similar

Initially, in the multisite, randomized controlled, outcome assessor–blinded, superiority trial, the outcomes were similar among the treatments, the authors write, but at 2 years only the surgery group maintained the success rate.

The primary outcome was more than 50% contracture release and patients reaching the patient-acceptable symptom state. Secondary outcomes included hand function, pain, patient satisfaction, quality of life, finger flexion, residual contracture angle, risk for retreatment, and serious adverse events.

A total of 292 (97%) and 284 (94%) patients completed the 3-month and 2-year follow ups, respectively.

Success rates at 3 months were similar: 71% (95% CI, 62%-80%) for surgery; 73% (95% CI, 64%-82%) for needle fasciotomy; and 73% (95% CI, 64%-82%) for collagenase injection.

At 2 Years, Surgery Superior

At 2 years, however, surgery had superior success rates. Surgery success rates vs needle fasciotomy were 78% vs 50% (adjusted risk difference, 0.30; 95% CI, 0.17-0.43).

Surgery success rates vs collagenase injection were 78% vs 65% (aRD, 0.13; 95% CI, 0.01-0.26).

“Secondary analyses paralleled with the primary analysis,” the authors write.

Patients may choose surgery despite initial morbidity which includes potential time off work and higher costs than the other options if the long-term outcome is better, the authors write.

“Collagenase is likely a viable alternative to needle fasciotomy only if its costs are substantially reduced,” the authors write.

A strength of the study is its generalizability, as researchers recruited patients in a setting with universal healthcare where few people seek care outside public hospitals.

Another strength of the trial is that the blinded outcome assessors measured the contracture angles with the participant’s hand covered by a rubber glove and patients were instructed not to reveal their treatment group to the assessor.

Some Physicians Offer Noninvasive Treatments First

Family physician Shannon Scott, DO, medical director of the Midwestern University Multispecialty Clinic in Scottsdale, Arizona, treats many patients with the contracture.

In her practice, patients come to her seeking noninvasive options first. But if they are not satisfied with their hand function after noninvasive treatments such as osteopathic manipulative treatment, physical therapy, and a home exercise program, the next steps are the choices compared in the study. The findings of this randomized controlled trial, she says, will help her in counseling patients choosing among those options.

“What’s important for me as a family physician to understand is more about the path that led to this decision” to seek more invasive treatment and whether the patients in the study had first completed a course of noninvasive care, Dr. Scott says.

The condition, especially in the population most affected — older adults — can greatly affect activities of daily living, she noted. Patients may also often have other conditions contributing to the symptoms of Dupuytren contracture in the neck, arm, or shoulder, for instance, that limit range of motion or cause pain. Addressing those symptoms noninvasively may help relieve the contracture, she says.

Asking patients about their goals is essential, Dr. Scott says. “What patients are looking for is function and the definition for one patient may be different than the level of function for another. Many patients get to a desired level of function with nonsurgical options first.”

A First for the Comparison

Dawn LaPorte, MD, a hand surgeon at Johns Hopkins Medicine in Baltimore, Maryland, who also was not part of the study, says although surgery was thought to have better long-term success rates, this is the first time the data have been able to show that at 2 years.

She added that the results are particularly striking because the endpoint was a 50% release when surgeons hope for a complete release. Even with the 50% release outcome at 2 years, surgery had better success.

She noted that the authors plan to look at outcomes at 5 and 10 years, but, she says, “the fact that surgery is already significantly better at 2 years really says a lot.”

Treatments Have Tradeoffs

She says the conclusions may change the discussions physicians have with patients.

Collagenase injections are an office procedure, and there’s no anesthesia. “There’s usually no lost time from work, and they can use their hand pretty normally the following day,” Dr. LaPorte says. One downside, compared with surgery, is that there may be a more frequent recurrence rate. Patients may have a skin tear that usually heals over a couple of weeks, she added.

Additionally, “the collagenase drug is very expensive,” she notes, so preapproval is important so that the patient doesn’t have to pay out of pocket.

Needle fasciotomy can also be done in the office without anesthesia. There’s less time off work than with surgery.

“With both that and the injection, they should see release of the contracture right away,” Dr. LaPorte says, but the concern is a quicker recurrence rate.

While surgery isn’t a cure, she says, and there is a lower recurrence rate, it typically means time off work, anesthesia, and an incision to heal, and may mean postoperative therapy.

The study was funded by the Research Council of Finland. Disclosures are available with the full text.

Dr. LaPorte and Dr. Scott report no relevant financial relationships.

Leading a healthy lifestyle, including regular exercise, eating fruits and vegetables, and minimal alcohol consumption, is associated with better cognitive function in older adults, new research showed.

The study, which combined longitudinal and cohort data with postmortem brain pathology reports, found that the association held even in those with Alzheimer’s disease (AD) pathology, suggesting that lifestyle factors may provide cognitive reserve and improve cognitive abilities in older age.

“While we must use caution in interpreting our findings, in part due to its cross-sectional design, these results support the role of lifestyle in providing cognitive reserve to maintain cognitive function in older adults despite the accumulation of common dementia-related brain pathologies,” Klodian Dhana, MD, of the Rush University Medical Center in Chicago, Illinois, and colleagues wrote.

The study was published online in JAMA Neurology.
 

Better Cognition

The study included 586 participants (71% female) who were followed from 1997 until 2022 as part of the Rush Memory and Aging Project longitudinal cohort study.

Investigators collected information on lifestyle and demographic factors at regular intervals, as well as information on diet, alcohol intake, and time spent participating in moderate or vigorous physical activity such as gardening, walking, calisthenics, biking, or swimming. Participants also received annual cognitive tests.

In later years, participants answered questions about whether they played card games or checkers, read, visited a museum, or did other cognitively stimulating activities.

Postmortem exams allowed the researchers to assess brain pathology (mean age at death, 91 years).

Participants were categorized as living a healthy lifestyle if they scored well in five categories: They exercised moderately or vigorously for 150 minutes per week, did not smoke, consumed one to two drinks per week, regularly played card games or did puzzles, and followed the Mediterranean-DASH Diet Intervention for Neurodegenerative Delay diet.

For every one-point increase in the healthy lifestyle score, there were 0.120 fewer units of beta-amyloid load in the brain and a 0.22 standardized unit higher score in cognitive performance (P < .001).

After adjusting for the beta-amyloid load, phosphorated tau tangle, or other dementia-related brain pathologies, the healthy lifestyle score remained independently associated with cognition (P < .001).

More than 88% of a person’s global cognition score was a “direct association of lifestyle,” investigators noted, leaving slightly less than 12% affected by the presence of beta-amyloid.

“The mechanistic link between lifestyle and cognition could be attributed in part to the antioxidant and anti-inflammatory capacities of each lifestyle factor (eg, nutrition and physical activity) and cognitive reserve (eg, cognitive activities) that contribute to less inflammation and oxidative stress,” the authors wrote.

Further studies are necessary, they added, especially research investigating the association of lifestyle factors with markers for inflammation to understand the mechanisms of how lifestyle is associated with better cognitive scores in old age.

Study limitations include the reliance on self-reported data because cognitive impairment could interfere with inaccurate reporting. In addition, the authors noted that cognitive abilities may affect adherence to lifestyle factors.
 

‘Important Evidence’

In an accompanying editorial, Yue Leng, MD, and Kristine Yaffe, MD, of the University of San Francisco in San Francisco, California, noted that the new study adds “important evidence” to the debate over modifiable risk factors and reduction of AD risk.

“These interesting results add strength to the concept that health and lifestyle factors are important strategies for prevention and suggest that several mechanisms may be at work,” they wrote, adding that the study is “one of the first to harness brain pathology to investigate these mechanisms and is a crucial step forward in addressing these important questions.”

Still, critical questions remain regarding the mechanistic pathways linking modifiable risk factors and cognitive aging, Drs. Leng and Yaffe wrote.

“There is an urgent need for more well-designed randomized controlled trials to pave the way for dementia risk reduction in the era of precision medicine,” they wrote. “These strategies should be offered in conjunction with AD medications, similar to the approach in cardiovascular disease prevention and treatment in which medications along with lifestyle strategies are the standard of care.”

The study was funded by the National Institute on Aging. Dr. Dhana reported grants paid to his institution from the Alzheimer’s Association. No other disclosures were reported.

Leading a healthy lifestyle, including regular exercise, eating fruits and vegetables, and minimal alcohol consumption, is associated with better cognitive function in older adults, new research showed.

The study, which combined longitudinal and cohort data with postmortem brain pathology reports, found that the association held even in those with Alzheimer’s disease (AD) pathology, suggesting that lifestyle factors may provide cognitive reserve and improve cognitive abilities in older age.

“While we must use caution in interpreting our findings, in part due to its cross-sectional design, these results support the role of lifestyle in providing cognitive reserve to maintain cognitive function in older adults despite the accumulation of common dementia-related brain pathologies,” Klodian Dhana, MD, of the Rush University Medical Center in Chicago, Illinois, and colleagues wrote.

The study was published online in JAMA Neurology.
 

Better Cognition

The study included 586 participants (71% female) who were followed from 1997 until 2022 as part of the Rush Memory and Aging Project longitudinal cohort study.

Investigators collected information on lifestyle and demographic factors at regular intervals, as well as information on diet, alcohol intake, and time spent participating in moderate or vigorous physical activity such as gardening, walking, calisthenics, biking, or swimming. Participants also received annual cognitive tests.

In later years, participants answered questions about whether they played card games or checkers, read, visited a museum, or did other cognitively stimulating activities.

Postmortem exams allowed the researchers to assess brain pathology (mean age at death, 91 years).

Participants were categorized as living a healthy lifestyle if they scored well in five categories: They exercised moderately or vigorously for 150 minutes per week, did not smoke, consumed one to two drinks per week, regularly played card games or did puzzles, and followed the Mediterranean-DASH Diet Intervention for Neurodegenerative Delay diet.

For every one-point increase in the healthy lifestyle score, there were 0.120 fewer units of beta-amyloid load in the brain and a 0.22 standardized unit higher score in cognitive performance (P < .001).

After adjusting for the beta-amyloid load, phosphorated tau tangle, or other dementia-related brain pathologies, the healthy lifestyle score remained independently associated with cognition (P < .001).

More than 88% of a person’s global cognition score was a “direct association of lifestyle,” investigators noted, leaving slightly less than 12% affected by the presence of beta-amyloid.

“The mechanistic link between lifestyle and cognition could be attributed in part to the antioxidant and anti-inflammatory capacities of each lifestyle factor (eg, nutrition and physical activity) and cognitive reserve (eg, cognitive activities) that contribute to less inflammation and oxidative stress,” the authors wrote.

Further studies are necessary, they added, especially research investigating the association of lifestyle factors with markers for inflammation to understand the mechanisms of how lifestyle is associated with better cognitive scores in old age.

Study limitations include the reliance on self-reported data because cognitive impairment could interfere with inaccurate reporting. In addition, the authors noted that cognitive abilities may affect adherence to lifestyle factors.
