Music may have health benefits for older adults, finds poll

Published

on

From stress relief and improved mood to keeping minds sharp and connecting to others, a poll of people aged 50 to 80 finds many positives from listening to or making music.

Whether it’s singing in a choir, playing the living room piano, joining in hymns at church, or just whistling along with the radio, a new poll finds that nearly all older adults say music brings them far more than just entertainment.

Three-quarters of people age 50 to 80 say music helps them relieve stress or relax and 65 per cent say it helps their mental health or mood, according to the new results from the University of Michigan National Poll on Healthy Aging. Meanwhile, 60 per cent say they get energised or motivated by music.

Those are just a few of the health-related benefits cited by older adults who answered questions about listening to and making music of all kinds.

Virtually all (98 per cent) said they benefit in at least one health-related way from engaging with music. In addition, 41 per cent say music is very important to them, with another 48 per cent saying it’s somewhat important.

“Music has the power to bring joy and meaning to life. It is woven into the very fabric of existence for all of humankind,” said Joel Howell, M.D., Ph.D., a professor of internal medicine at the U-M Medical School who worked with the poll team.

Music also has tangible effects on a variety of health-related ailments, he adds. “We know that music is associated with positive effects on measures from blood pressure to depression.”

The poll is based at the U-M Institute for Healthcare Policy and Innovation and supported by AARP and Michigan Medicine, the University of Michigan’s academic medical centre. The poll team asked a national sample of adults aged 50 to 80 about their experiences with and feelings toward listening to and making music.

Many older adults reported making music with other people at least occasionally, whether by singing or playing an instrument. In all, eight per cent said they have sung in a choir or other organised group at least a few times in the past year. About eight per cent of all older adults said they play an instrument with other people at least occasionally.

In all, 46 per cent of older adults reported singing at least a few times a week, and 17 per cent said they play a musical instrument at least a few times a year.

Most respondents reported listening to music, with 85 per cent saying they listen to it at least a few times a week, 80 per cent saying they’ve watched musical performances on television or the internet at least a few times in the past year, and 41 per cent saying they had attended live musical performances in person at least a few times in the past year. That latter percentage was higher among those with higher incomes and more education.

The poll shows other differences between groups in music listening habits and health impacts.

Those who said their physical health is fair or poor, and those who say they often feel isolated, were less likely to listen to music every day. Black older adults were more likely than others to have sung in a choir in the past year, and Black and Hispanic older adults were more likely to say that music is very important to them.

“While music doesn’t come up often in older adults’ visits with their usual care providers, perhaps it should,” said poll director Jeffrey Kullgren, M.D., M.P.H., M.S.

“The power of music to connect us, improve mood and energy, or even ease pain (like 7% of respondents said it does for them), means it could be a powerful tool.” Kullgren is a primary care physician at the VA Ann Arbor Healthcare System and associate professor of internal medicine at U-M.

Howell notes that music helps people keep in touch with one another throughout their lifetime. Indeed, 19 per cent of the poll respondents said music is even more important to them now than it was in their youth, and 46 per cent said it’s just as important to them now as then.

With the rising concern about the health effects of loneliness and social isolation among Americans in general, and especially among older adults, the power of music to connect people and support healthy aging should not be underestimated, Howell says. The NPHA has previously reported on trends in loneliness and social isolation in older adults.

“Music is a universal language that has powerful potential to improve wellbeing,” said Sarah Lenz Lock, senior vice president of Policy and Brain Health at AARP and executive director of the Global Council on Brain Health.

“AARP’s own research shows that music can play an important role in healthy aging by improving our moods, fostering social connections and, potentially, enriching our brain health.”

Palliative care beneficial to manage symptoms, improve quality of life for people with CVD

Published

on

Implementing patient-centered palliative care therapies, including prescribing, adjusting or discontinuing medications as needed, may help control symptoms and improve quality of life for people with heart disease, according to a new scientific statement from the American Heart Association.

Decisions about initiating, adjusting or discontinuing cardiovascular and other medicines should be patient-centered and include input from multiple specialties including cardiology experts in close collaboration with primary care professionals.

Evidence shows that adding palliative care interventions to standard cardiovascular care improves outcomes for patients with heart disease. However, the latest research indicates palliative care is underutilised, especially among people from underrepresented racial and ethnic groups who are affected by unfavourable social determinants of health and health inequities.

The American Heart Association’s statement, published in the Association’s journal, Circulation: Cardiovascular Quality and Outcomes, reviews current evidence on the benefits and risks of cardiovascular and essential palliative medications.

The statement provides guidance for health care professionals to incorporate palliative methods as part of holistic medication management at all stages of a patient’s health conditions, emphasizing the importance of shared decision-making and goal-oriented care.

Palliative care is specialised medical care that aims to relieve symptoms and enhance quality of life for people experiencing health-related issues due to serious illnesses. This approach may benefit patients with cardiovascular disease, including coronary heart disease, valvular heart disease, pulmonary arterial hypertension and heart failure. These conditions significantly reduce quality of life, require ongoing treatment, are usually progressive and are associated with high mortality rates. The progression of many conditions, from chronic to advanced and end-stage, may be unpredictable and marked by worsening symptoms that result in recurrent hospitalisation.

Palliative care complements standard cardiovascular care by reducing physical symptoms, managing emotional distress and assisting patients in making decisions that coincide with their goals of care. A palliative approach can be integrated into the medication management of patients at any stage of heart disease, from chronic, stable heart disease to advanced and end-stage cardiovascular disease. And, importantly, palliative care supports a more goal-oriented, patient-centered approach to treatment.

Previous studies have found that adding palliative care interventions to evidence-based care improved patients’ quality of life, functional status, depression, anxiety and spiritual well-being and reduced the risk of hospital readmission for patients with advanced heart disease compared to clinical care alone. Despite these benefits, fewer than 20% of people with end-stage heart disease receive palliative care.

In addition, despite significant progress in cardiovascular care, disparities in care and outcomes related to race, ethnicity, gender and social determinants of health persist. People with heart failure who are referred to palliative care are predominantly white, have higher socioeconomic status and are more likely to receive care at academic medical centers. Patients from underrepresented racial and ethnic groups are less likely to receive palliative care, which contributes to poorer outcomes and increased risk of early mortality.

“It is critical for patients to be fully informed about their diagnosis and how medication management may change throughout the disease progression so they have ample time to set and share their goals,” said Chair of the statement writing group Katherine E. Di Palo, Pharm.D., M.B.A., M.S., FAHA, senior director of Transitional Care Excellence at Montefiore Medical Center and assistant professor of medicine at Albert Einstein College of Medicine in New York City.

“These goals often include reducing symptoms such as shortness of breath, fatigue, and pain as well as improving sleep, mood and appetite.”

To achieve these goals, cardiovascular medications that provide symptom relief, such as diuretics to manage fluid retention in heart failure, should be prioritised in patients with advanced heart disease.

Adding palliative medicines to evidence-based cardiovascular therapies can be complementary to manage symptoms and optimise quality of life. Examples of common palliative medicines include antidepressants, opioids for pain relief and difficulty breathing, and anti-nausea medications.

“Given the complexities of medication management in people with heart disease, a team-based approach is urged. Collaboration between multidisciplinary clinicians across primary care, cardiology and palliative care is needed to deliver effective, person-centered care,” said Di Palo.

Because the health status of patients can change rapidly, it is crucial to have ongoing discussions to ensure that treatment plans align with the patient’s preferences and priorities. Clinicians should routinely evaluate — and clearly communicate — to patients and their families about the potential risks, benefits and expected time to benefit of each medication.

Deprescribing and de-escalating medications are also essential components of palliative medication management for people with heart disease. Deprescribing involves tapering, withdrawing or discontinuing a medication to improve outcomes. De-escalating medications focuses on reducing the dose or switching to another medication based on the patient’s response to the medicine.

“Deprescribing that targets medications with limited benefit or increased risk of adverse events can be done safely with patient permission,” Di Palo said.

The statement provides several examples where deprescribing medications may be appropriate to consider, such as when the time to benefit from the medication may be longer than the patient’s life-expectancy.

Anti-clotting medications (also known as anticoagulants) may be prescribed to reduce the risk of blood clots. However, some of these medicines may increase the risk of bleeding, especially in older patients over the age of 75 who are at increased risk of falls.

Discontinuing non-steroidal anti-inflammatories (NSAIDs) may also be considered in patients with end-stage heart disease due to increased risk of bleeding and fluid retention. Although beta-blockers are commonly prescribed for high blood pressure and heart failure, they may contribute to fatigue and functional decline in end-stage heart disease. A slow-tapering schedule can help to reduce the risk of rebound high blood pressure or withdrawal when large doses are abruptly stopped.

Other reasons to consider deprescribing medications include polypharmacy, defined as taking five medications or more daily. This increases the risk of adverse reactions or side effects, not taking medications as prescribed, hospital readmission and mortality. Excessive out-of-pocket medication costs may also prompt the need to deprescribe certain medications.

Future research is needed to determine the best ways to provide timely and targeted access to palliative medication management, particularly for patients with advanced heart disease from under-represented racial and ethnic groups who are less likely to receive palliative care or may face barriers to care.

How the ketogenic diet improves healthspan and memory in aging mice

Published

on

The ketogenic diet has its fanatics and detractors among dieters, but either way, the diet has a scientifically documented impact on memory in mice.

While uncovering how the high fat, low carbohydrate diet boosts memory in older mice, Buck scientists and a team from the University of Chile identified a new molecular signalling pathway that improves synapse function and helps explain the diet’s benefit on brain health and aging.

Published in the June 5, 2024 issue of Cell Reports Medicine, the findings provide new directions for targeting the memory effects on a molecular level, without requiring a ketogenic diet or even the by-products of it.

“Our work indicates that the effects of the ketogenic diet benefit brain function broadly, and we provide a mechanism of action that offers a strategy for the maintenance and improvement of this function during aging,” said the study’s senior author, Christian González-Billault, PhD, who is a professor at the Universidad de Chile and director of their Geroscience Center for Brain Health and Metabolism, and adjunct professor at the Buck Institute.

“Building off our previous work showing that a ketogenic diet improves health span and memory in aging mice, this new work indicates that we can start with older animals and still improve the health of the aging brain, and that the changes begin to happen relatively quickly,” said John Newman, MD, PhD, whose laboratory at Buck collaborated with Dr. González-Billault on the study. Newman is both an assistant professor at the Buck Institute, and a geriatrician at University of California, San Francisco.

“It is the most detailed study to date of the ketogenic diet and aging brain in mice.”

More than a century ago, researchers observed that rats that consumed less food lived longer. “We now know that being able to manipulate lifespan is not about specifically eating less,” said Newman, but actually is related to signals inside cells that turn on and off specific pathways in response to available nutrients. Many of those pathways are related to aging, such as controlling protein turnover and metabolism.

Some of those signals are the ketone bodies, which consist of acetoacetate (AcAc), β-hydroxybutyrate (BHB) and to a much lesser extent, acetone. These molecules are routinely produced in the liver. They ramp up when glucose is in short supply, whether due to caloric restriction, intense exercise or low carbohydrate intake, such as with a ketogenic diet.

Seven years ago, Newman led a team that published the first proof of the concept that if a ketogenic diet exposes mice to increased levels of ketone bodies over much of their adult life, it helps them to live longer and age in a more healthy way. “The most striking effect on their health as they aged was that their memory was preserved; it was possibly even better than when they were younger,” he said.

The current study, designed to answer what part of the ketogenic diet was having the effect and how it was affecting the brain on a molecular level to improve memory, was led by González-Billault in a collaboration with scientists at the Buck. Mice on a ketogenic diet are fed a ratio of 90 percent calories from fat and 10 percent from protein, while mice on a control diet received the same amount of protein but only 13 percent fat. The test mice, of “advanced age” of more than two years old, received one week of the ketogenic diet, cycled with one week of the control diet, to keep the mice from overeating and becoming obese.

The benefits of the ketogenic diet, said, González-Billault, were demonstrated through neurophysiological and behavioural experiments with the mice that test how well the mechanisms involved in memory generation, storage, and retrieval function in aged animals. When these showed that the ketogenic diet appeared to benefit how well the synapses responsible for memory worked, they took a deep dive into the protein composition at these synapses in the hippocampus, in a collaboration with Buck professor Birgit Schilling, PhD, who directs the Proteomics and Mass Spectrometry Center.

“Surprisingly, we saw that the ketogenic diet caused dramatic changes in the proteins of the synapse,” said Schilling. Even more surprising, she said, was that the changes started after a relatively brief exposure to the diet (tested after only one week on the diet) and only became more pronounced over time (tested again after six weeks and a year).

Further testing indicated that in synapses, a particular signalling pathway (protein kinase A, which is critical to synapse activity) was activated by the ketogenic diet. In isolated cells, the team then showed that it appears that BHB, the main ketone body produced in a ketogenic diet, is activating this pathway. This leads to the idea, said González-Billault, that ketone bodies (specifically BHB) play a crucial role not only as an energy source, but also as a signalling molecule.

“BHB is almost certainly not the only molecule in play, but we think this is an important part of understanding how the ketogenic diet and ketone bodies work,” said Newman “This is the first study to really connect deep molecular mechanisms of ketone bodies all the way through to improving the aging brain.”

Looking forward, he said, the next step would be to see if the same memory protection could be achieved by using BHB alone, or possibly going even more targeted than that by manipulating the protein kinase A signalling pathway directly. “If we could recreate some of the big-picture effects on synapse function and memory just by manipulating that signalling pathway in the right cells,” he said, “we wouldn’t even need to eat a ketogenic diet in the end.”

The impact of lifestyle intervention in rheumatoid arthritis

Patients with rheumatoid arthritis have unique autoantibody patterns

A 16-week Plants for Joints trial investigated the effects of a multidisciplinary lifestyle intervention in people with rheumatoid arthritis (RA), as compared to usual care.

The intervention was based on a whole-food, plant-based diet – alongside physical activity and stress management. Previous reports showed this intervention significantly reduced the 28-joint disease activity score compared to usual care alone.

To expand on this, the researchers wanted to determine the long-term effectiveness of the intervention, specifically with regards to disease activity after two years.

After the initial 16-week randomised period, the control group also received the intervention, and participants were followed for 2 years with biannual visits and six adherence-promoting webinars annually. People with DAS28 <2.6 also received a protocol as a suggested approach to try tapering their antirheumatic medication – under the supervision of their rheumatologist – and any treatment changes were recorded.

In total, 62% of the original trial completers also completed the two-year follow-up. Those who discontinued most often indicated that this was because they were too busy, unreachable, or did not give permission for the second year of the extension study.

The long-term results showed that improvement in DAS28 was maintained for two years after completing the intervention – and was significantly lower compared to baseline. Tender joint count and general health components of the DAS28 also improved significantly, although there was no significant difference in the erythrocyte sedimentation rate and swollen joint count compared to baseline.

Results were similar in people who completing the two-year extension study versus those that discontinued prematurely.

Of the 39 participants who completed their follow-up and used disease-modifying antirheumatic medication, 44% were able to decrease or stop, 26% had stable usage, and 31% had increased medication. Of those with stable or decreased medication compared to baseline, 65% had improved DAS28.

After the two-year follow-up, HDL-cholesterol was increased and C-reactive protein (CRP) remained significantly lower compared to baseline values – although there was no longer a significant difference in weight, waist circumference, LDL-cholesterol, or HbA1c.

These findings indicate that intensive lifestyle modifications can be effective in the long term for people with RA.
