In older individuals with chronic kidney disease (CKD), a higher intake of animal or plant protein is associated with reduced mortality. This finding comes from an analysis of three cohorts from Spain and Sweden, the results of which were published in JAMA Network Open.

In old age, our protein requirement increases. The recommended protein intake is between 1.0 and 1.2 g per kg of actual body weight per day. For elderly patients with acute and chronic illnesses, injuries, or malnutrition, the requirement may be higher.

“While older adults may need more protein than younger persons, higher protein intake could accelerate disease progression among those with CKD, a prevalent condition in older adults that often has no cure and high morbidity and mortality,” wrote Dr. Adrián Carballo-Casla of the Aging Research Center at the Karolinska Institutet in Stockholm, Sweden, and his colleagues.
 

Protein Restriction

The current Kidney Disease: Improving Global Outcomes guideline recommends that patients with mild CKD (ie, stages 1 and 2) not consume more than 1.3 g/kg/day of protein. In stages 3-5 (without dialysis) of CKD, protein intake should be limited to 0.6-0.8 g/kg/day. “Such a regimen of lower protein intake has been shown to slow CKD progression rates and improve metabolic derangements in persons with CKD stages 4 and 5 not receiving dialysis,” the researchers wrote. “Insufficient evidence of the overall health impact of limiting protein intake in older persons with mild or moderate CKD, and whether this impact is different in older adults without CKD, is available.”

The authors analyzed data from three cohorts from Spain and Sweden that included 8543 participants aged at least 60 years. A total of 14,399 observations were analyzed, including 4789 participants with CKD stages 1-3 and 9610 without CKD. To capture protein intake over a longer period and minimize variations among individual study participants, the researchers arranged the data so that there was one observation per time interval for each participant. During the 10-year follow-up, 1468 deaths were documented.

“We observed an inverse association between total protein intake and mortality among participants with CKD but a somewhat weaker one than among those without CKD,” the researchers wrote.
 

Slightly Weaker Association

Compared with participants with a protein intake of 0.8 g/kg/day, participants with CKD who consumed 1.0 g/kg/day of protein had a 12% reduced risk for death. At an intake of 1.2 g/kg/day, the mortality risk decreased by 21%. It decreased by 27% at a protein intake of 1.4 g/kg/day. In patients without CKD, the corresponding risk reductions were 23%, 37%, and 44%.

While in participants without CKD, mortality decreased by 15% with each increase in protein intake of 0.2 g/kg/day, in patients with CKD, the decrease was only 8%.

The association did not change according to whether the protein was of animal or plant origin. The age of the study participants (ie, whether they were under or over age 75 years) also did not play a role.
 

Benefits Outweigh Drawbacks

The researchers pointed out that the biological effects of protein sources could depend on the total intake, as well as the proportion of plant protein in the diet. “Not only did 68% of total protein come from animal sources in our study, but also the mean protein intake was well above the current recommendations for persons with moderate CKD,” they wrote. It is therefore unclear whether the results could be extrapolated to older patients who follow a plant-based or low-protein diet.

“The stronger associations in participants without CKD suggest that the benefits of proteins may outweigh the downsides in older persons with mild or moderate CKD,” the researchers concluded.

Colonoscopy remains the gold standard method for detecting colorectal cancer (CRC) and removing precancerous polyps.

The recommended age for CRC screening in the United States spans 45-75 years, with the benefits of colonoscopy diminishing considerably after this point.

Older adults are much more likely to experience complications before, during, and after a colonoscopy. Bowel preps can cause dehydration or electrolyte problems in some, while bleeding and bowel perforation can occur perioperatively, and pulmonary or cardiovascular complications may arise postoperatively.

These risks often outweigh the benefits of catching a precancerous lesion or early-stage cancer, especially given the low rates of advanced neoplasia and CRC detected from screening and surveillance after age 75. Yet the research overall suggests that more than half of older individuals continue to receive screening and surveillance colonoscopies outside the recommended screening window.

So is there a point in time when a person is too old to receive a colonoscopy? The answer is not always clear-cut, but life expectancy should be a key consideration.

“Taking the most extreme example, if you have 6 months to live, finding early-stage cancer is not going to help you,” Michael Rothberg, MD, vice chair for research at Cleveland Clinic’s Medical Institute and director of the Center for Value-Based Care Research, told Medscape Medical News.

For those with more time, the benefits of continued screening and surveillance may outweigh the risks, but when that balance shifts from helpful to not helpful remains inexact, Dr. Rothberg noted.

What’s Recommended?

In May 2021, the US Preventive Services Task Force (USPSTF) lowered the CRC screening threshold to age 45, recommending all adults aged between 45 and 75 years receive screening.

For those aged between 76 and 85 years, the USPSTF upheld its 2016 recommendation of selective screening, noting that the “net benefit of screening all persons in this age group is small” and should be determined on an individual basis. The USPSTF, however, did not provide recommendations on surveillance colonoscopies among those with previously identified polyps.

In November 2023, the American Gastroenterological Association (AGA) issued a clinical practice update that provided advice on risk stratification for CRC screening and post-polypectomy surveillance. For adults older than 75 years specifically, the AGA recommended that the decision to continue CRC screening or perform post-polypectomy surveillance be based on risks, benefits, comorbidities, and screening history and decided on a case-by-case basis.

For instance, previously unscreened patients without comorbidities could benefit from screening beyond age 75 — up to age 80 for men and 90 for women — while those who have had regular colonoscopies, per recommended guidelines, but severe comorbidities that may limit life expectancy could stop sooner, even by age 65.

Although an individualized approach leaves room for variation, it’s essential to consider life expectancy and the time it takes for a polyp to progress to CRC, as well as the risks associated with the procedure itself. Certain older adults are “less likely to live long enough to benefit from surveillance colonoscopy, due to competing, non-CRC mortality risks,” and clinicians should discuss these risks with their patients, the experts explained.
 

When to Stop Screening Colonoscopies

Research shows that screening colonoscopies continue well after the recommended stop age.

A 2023 JAMA Internal Medicine study found, for instance, that a large proportion of screening colonoscopies occurred among the 7067 patients who were 75 years and older with a life expectancy < 10 years. Overall, 30% of patients aged between 76 and 80 years with a limited life expectancy had a colonoscopy. That percentage increased to 71% for those aged 81-85 years and to 100% for those older than 85 years.

But the benefits of screening were minimal. Overall, colonoscopies detected advanced neoplasia in 5.4% of patients aged 76-80 years, 6.2% of those aged 81-85 years, and 9.5% of those older than 85 years. Only 15 patients (0.2%) had CRC detected via colonoscopy, five of whom underwent cancer treatment. Of those five, four had a life expectancy ≥ 10 years, and one had a life expectancy < 10 years.

At the same time, adverse events requiring hospitalization were common 10 days post-colonoscopy (13.58 per 1000), and the risk for hospitalization increased with age.

“For all kinds of screening, we’re not that comfortable in America with the idea that people are eventually going to die, but as you get older, the potential benefits for screening decrease,” study author Dr. Rothberg told this news organization.

In general, life expectancy provides a good predictor of whether people should continue screening or receive treatment following a CRC diagnosis.

Patients aged 76-80 years in good health, for instance, could benefit from screening and, potentially, treatment, Dr. Rothberg said. And “if doctors don’t feel comfortable or confident about predicting life expectancy, taking comorbid illnesses into account can be helpful, especially for that age range.”
 

Weighing Surveillance Benefits

Surveillance colonoscopy is often recommended post-polypectomy to reduce the risk for CRC. But even in this higher-risk population, those older than 75 years may not benefit.

Recent evidence indicates that those with a history of one or two adenomas less than 1 cm in size have only a slightly (1.3-fold) increased risk for incident CRC — and no significant increased risk for fatal CRC.

Another recent study found that detecting CRC at surveillance colonoscopy was rare among older adults. In surveillance colonoscopies performed among 9601 individuals aged 70-85 years with prior adenomas, 12% had advanced neoplasia detected, and only 0.3% had CRC detected.

Similar rates of advanced polyps (7.8%) or CRC (0.2%) were reported in another recent analysis of more than 9800 adults older than 65 years receiving surveillance colonoscopies.

Despite the low rates of polyp and CRC detection, nearly 90% of patients with recommendation information available received advice to return for a future colonoscopy. Even among patients with no polyps or small ones, almost 60% who had life expectancy of less than 5 years were told to return.

Although someone with prior adenomas has a higher risk for CRC, that doesn’t tell the whole story for an individual patient, Samir Gupta, MD, professor of gastroenterology at the University of California San Diego, and co-lead of the Cancer Control Program at Moores Cancer Center, told this news organization. For older adults, it’s vital to consider the competing risks and how much time it might take for CRC to develop.

At Digestive Disease Week in May, Dr. Gupta presented new research that looked at cumulative risk among patients aged 75 years and older with prior precancerous polyps vs prior normal colonoscopies. Although those with prior adenomas had a higher risk for CRC overall, their cumulative CRC risk was low — about 0.3% at 5 years and 0.8% at 10 years. Cumulative CRC deaths were even lower — 0.2% at 5 years and 0.7% at 10 years — while the risk of dying from something other than CRC was 20% at 5 years and 40% at 10 years.

“What this means to me is that patients who are 75 and older should think really carefully about whether they want to do surveillance,” said Dr. Gupta, who coauthored the AGA’s clinical practice update. “Someone who is very healthy and doesn’t have obvious medical problems can look at that risk for developing colon cancer and the risk of dying and make a decision about whether there’s enough concern to go ahead with surveillance.”

Those with competing health priorities, on other hand, should likely concentrate on those instead, he said, and feel reassured that even if they choose not to do surveillance, they’re probably not doing themselves any harm.

“The bottom line is that referring older adults or frail adults for surveillance colonoscopy shouldn’t be a rubber stamp or check-the-box action,” Dr. Gupta said. “We need to think about it carefully and give ourselves — as clinicians and patients — the room to decide that it may not need to take high priority.”
 

What to Tell Patients

Overall, older adults who have had prior colonoscopies, no or low-risk polyps, and low CRC risk will likely face greater risks from the procedure than benefits.

“The more invasive the screening the test, the more dangerous it could be,” Dr. Rothberg noted.

Many patients, however, are open to stopping and often trust their primary care provider in the decision-making process, said Audrey Calderwood, MD, director of the Comprehensive Gastroenterology Center at Dartmouth Hitchcock Medical Center. “But the systems we have in place don’t optimally support that decision-making at the time it matters most.”

For example, at a prior colonoscopy, a gastroenterologist may recommend surveillance again in 5-7 years. But in the interim, the patient could have new medications or develop comorbidities and other health issues. Rather than defer to the gastroenterologist’s recommendations from years ago, clinicians and patients can reassess the pros and cons of screening or surveillance based on current circumstances, Dr. Calderwood said.

“There should be lines of communication and systems of support to allow primary care providers to decide whether it is still needed,” she said.

While some may be ready to stop, other patients are going to continue to want and ask about CRC screening or surveillance, Dr. Rothberg said.

In these instances, communication style matters.

“You don’t want to tell a patient that they’re not going to be screened because they’re not going to live long enough to benefit,” Dr. Rothberg said.

However, steering people toward less invasive tests or telling them it’s important to give other health problems priority may be more sensitive ways to communicate that it’s time to ramp down or halt screening.

“Sometimes when you say you’re going to stop cancer screening, older adults misperceive that you’re giving up on them,” Dr. Gupta said. “We spend 30-40 years driving home the message that prevention and screening are important, and then it feels like we’re taking it away, so we need to find the best way to discuss it and make the choice that’s comfortable for them.”

Dr. Rothberg, Dr. Gupta, and Dr. Calderwood disclosed no relevant conflicts of interest.

Weighing Surveillance Benefits

Surveillance colonoscopy is often recommended post-polypectomy to reduce the risk for CRC. But even in this higher-risk population, those older than 75 years may not benefit.

Recent evidence indicates that those with a history of one or two adenomas less than 1 cm in size have only a slightly (1.3-fold) increased risk for incident CRC — and no significant increased risk for fatal CRC.

For instance, previously unscreened patients without comorbidities could benefit from screening beyond age 75 — up to age 80 for men and 90 for women — while those who have had regular colonoscopies, per recommended guidelines, but severe comorbidities that may limit life expectancy could stop sooner, even by age 65.

Although an individualized approach leaves room for variation, it’s essential to consider life expectancy and the time it takes for a polyp to progress to CRC, as well as the risks associated with the procedure itself. Certain older adults are “less likely to live long enough to benefit from surveillance colonoscopy, due to competing, non-CRC mortality risks,” and clinicians should discuss these risks with their patients, the experts explained.
 

When to Stop Screening Colonoscopies

Research shows that screening colonoscopies continue well after the recommended stop age.

A 2023 JAMA Internal Medicine study found, for instance, that a large proportion of screening colonoscopies occurred among the 7067 patients who were 75 years and older with a life expectancy < 10 years. Overall, 30% of patients aged between 76 and 80 years with a limited life expectancy had a colonoscopy. That percentage increased to 71% for those aged 81-85 years and to 100% for those older than 85 years.

But the benefits of screening were minimal. Overall, colonoscopies detected advanced neoplasia in 5.4% of patients aged 76-80 years, 6.2% of those aged 81-85 years, and 9.5% of those older than 85 years. Only 15 patients (0.2%) had CRC detected via colonoscopy, five of whom underwent cancer treatment. Of those five, four had a life expectancy ≥ 10 years, and one had a life expectancy < 10 years.

At the same time, adverse events requiring hospitalization were common 10 days post-colonoscopy (13.58 per 1000), and the risk for hospitalization increased with age.

“For all kinds of screening, we’re not that comfortable in America with the idea that people are eventually going to die, but as you get older, the potential benefits for screening decrease,” study author Dr. Rothberg told this news organization.

In general, life expectancy provides a good predictor of whether people should continue screening or receive treatment following a CRC diagnosis.

Patients aged 76-80 years in good health, for instance, could benefit from screening and, potentially, treatment, Dr. Rothberg said. And “if doctors don’t feel comfortable or confident about predicting life expectancy, taking comorbid illnesses into account can be helpful, especially for that age range.”
 

Weighing Surveillance Benefits

Surveillance colonoscopy is often recommended post-polypectomy to reduce the risk for CRC. But even in this higher-risk population, those older than 75 years may not benefit.

Recent evidence indicates that those with a history of one or two adenomas less than 1 cm in size have only a slightly (1.3-fold) increased risk for incident CRC — and no significant increased risk for fatal CRC.

Another recent study found that detecting CRC at surveillance colonoscopy was rare among older adults. In surveillance colonoscopies performed among 9601 individuals aged 70-85 years with prior adenomas, 12% had advanced neoplasia detected, and only 0.3% had CRC detected.

Similar rates of advanced polyps (7.8%) or CRC (0.2%) were reported in another recent analysis of more than 9800 adults older than 65 years receiving surveillance colonoscopies.

Despite the low rates of polyp and CRC detection, nearly 90% of patients with recommendation information available received advice to return for a future colonoscopy. Even among patients with no polyps or small ones, almost 60% who had life expectancy of less than 5 years were told to return.

Although someone with prior adenomas has a higher risk for CRC, that doesn’t tell the whole story for an individual patient, Samir Gupta, MD, professor of gastroenterology at the University of California San Diego, and co-lead of the Cancer Control Program at Moores Cancer Center, told this news organization. For older adults, it’s vital to consider the competing risks and how much time it might take for CRC to develop.

At Digestive Disease Week in May, Dr. Gupta presented new research that looked at cumulative risk among patients aged 75 years and older with prior precancerous polyps vs prior normal colonoscopies. Although those with prior adenomas had a higher risk for CRC overall, their cumulative CRC risk was low — about 0.3% at 5 years and 0.8% at 10 years. Cumulative CRC deaths were even lower — 0.2% at 5 years and 0.7% at 10 years — while the risk of dying from something other than CRC was 20% at 5 years and 40% at 10 years.

“What this means to me is that patients who are 75 and older should think really carefully about whether they want to do surveillance,” said Dr. Gupta, who coauthored the AGA’s clinical practice update. “Someone who is very healthy and doesn’t have obvious medical problems can look at that risk for developing colon cancer and the risk of dying and make a decision about whether there’s enough concern to go ahead with surveillance.”

Those with competing health priorities, on other hand, should likely concentrate on those instead, he said, and feel reassured that even if they choose not to do surveillance, they’re probably not doing themselves any harm.

“The bottom line is that referring older adults or frail adults for surveillance colonoscopy shouldn’t be a rubber stamp or check-the-box action,” Dr. Gupta said. “We need to think about it carefully and give ourselves — as clinicians and patients — the room to decide that it may not need to take high priority.”
 

What to Tell Patients

Overall, older adults who have had prior colonoscopies, no or low-risk polyps, and low CRC risk will likely face greater risks from the procedure than benefits.

“The more invasive the screening the test, the more dangerous it could be,” Dr. Rothberg noted.

Many patients, however, are open to stopping and often trust their primary care provider in the decision-making process, said Audrey Calderwood, MD, director of the Comprehensive Gastroenterology Center at Dartmouth Hitchcock Medical Center. “But the systems we have in place don’t optimally support that decision-making at the time it matters most.”

For example, at a prior colonoscopy, a gastroenterologist may recommend surveillance again in 5-7 years. But in the interim, the patient could have new medications or develop comorbidities and other health issues. Rather than defer to the gastroenterologist’s recommendations from years ago, clinicians and patients can reassess the pros and cons of screening or surveillance based on current circumstances, Dr. Calderwood said.

“There should be lines of communication and systems of support to allow primary care providers to decide whether it is still needed,” she said.

While some may be ready to stop, other patients are going to continue to want and ask about CRC screening or surveillance, Dr. Rothberg said.

In these instances, communication style matters.

“You don’t want to tell a patient that they’re not going to be screened because they’re not going to live long enough to benefit,” Dr. Rothberg said.

However, steering people toward less invasive tests or telling them it’s important to give other health problems priority may be more sensitive ways to communicate that it’s time to ramp down or halt screening.

“Sometimes when you say you’re going to stop cancer screening, older adults misperceive that you’re giving up on them,” Dr. Gupta said. “We spend 30-40 years driving home the message that prevention and screening are important, and then it feels like we’re taking it away, so we need to find the best way to discuss it and make the choice that’s comfortable for them.”

Dr. Rothberg, Dr. Gupta, and Dr. Calderwood disclosed no relevant conflicts of interest.

TOPLINE:

Older adults with untreated hypertension have a 36% increased risk for Alzheimer’s disease (AD) compared with those without hypertension and a 42% increased risk for AD compared with those with treated hypertension.

METHODOLOGY:

• In this meta-analysis, researchers analyzed the data of 31,250 participants aged 60 years or older (mean age, 72.1 years; 41% men) from 14 community-based studies across 14 countries.
• Mean follow-up was 4.2 years, and blood pressure measurements, hypertension diagnosis, and antihypertensive medication use were recorded.
• Overall, 35.9% had no history of hypertension or antihypertensive medication use, 50.7% had a history of hypertension with antihypertensive medication use, and 9.4% had a history of hypertension without antihypertensive medication use.
• The main outcomes were AD and non-AD dementia.

TAKEAWAY:

• In total, 1415 participants developed AD, and 681 developed non-AD dementia.
• Participants with untreated hypertension had a 36% increased risk for AD compared with healthy controls (hazard ratio [HR], 1.36; P = .041) and a 42% increased risk for AD (HR, 1.42; P = .013) compared with those with treated hypertension.
• Compared with healthy controls, patients with treated hypertension did not show an elevated risk for AD (HR, 0.961; P = .6644).
• Patients with both treated (HR, 1.285; P = .027) and untreated (HR, 1.693; P = .003) hypertension had an increased risk for non-AD dementia compared with healthy controls. Patients with treated and untreated hypertension had a similar risk for non-AD dementia.

IN PRACTICE:

“These results suggest that treating high blood pressure as a person ages continues to be a crucial factor in reducing their risk of Alzheimer’s disease,” the lead author Matthew J. Lennon, MD, PhD, said in a press release.

TOPLINE:

Age-related hearing loss and peripheral neuropathy in older adults reduce longevity both directly and indirectly by affecting balance and gait.

METHODOLOGY:

• Researchers analyzed 793 older adults recruited from primary care practices participating in the OKLAHOMA Studies in 1999.
• Participants completed a questionnaire and underwent a physical examination; timed gait assessments (50 ft); and tests for peripheral nerve function, balance, and hearing.
• Hearing thresholds were tested at 20, 25, and 40 dB, respectively, and at sound frequencies of 500, 1000, 2000, and 4000 Hz.
• Researchers tracked mortality data over 22 years.

TAKEAWAY:

• Overall, 83% participants experienced hearing loss. Regular use of hearing aids was low, reported in 19% and 55% of those with moderate and severe hearing loss, respectively.
• Hearing loss was linked to impaired balance (P = .0014), slower walking (P = .0024), and reduced survival time (P = .0001). Moderate to severe hearing loss was strongly associated with reduced survival time (odds ratio, 1.36; P = .001), independent of the use of hearing aids.
• Peripheral neuropathy was present in 32% participants. The condition also increased the risk for death over the study period (hazard ratio [HR], 1.32; P = .003). Participants with both hearing loss and peripheral neuropathy showed reduced balance and survival time compared with people with either condition alone (HR, 1.55; P < .0001).

IN PRACTICE:

“Like peripheral neuropathy, advanced-age hearing loss is associated with reduced life expectancy, probably mediated in part through an adverse impact on balance,” the authors wrote. “Greater appreciation for the serious impacts of hearing loss and peripheral neuropathy could lead to further efforts to understand their causes and improve prevention and treatment strategies.”

SOURCE:

The study was led by James W. Mold, MD, MPH, of the University of Oklahoma Health Sciences Center, Oklahoma City. It was published online in the Journal of the American Geriatrics Society.

LIMITATIONS:

The dataset was collected in 1999 and may not entirely represent the current cohorts of older primary care patients. The absence of soundproof rooms and the exclusion of some components of the standard audiometric evaluation may have affected low-frequency sound measurements. Furthermore, physical examination was a less accurate measure of peripheral neuropathy. Information on the duration or severity of predictors and causes of death was not available.

DISCLOSURES:

The study was funded by the Presbyterian Health Foundation. The authors did not disclose any competing interests.

As more data show potentially dangerous effects of climate and weather on individuals with chronic medical conditions, CVS Health has introduced an initiative that uses technology to provide weather alerts and targeted outreach to those at increased risk, according to a press release from the company. Ultimately, the goals of the initiative are to improve health, reduce emergency department visits, hospital stays, and medical costs, according to the press release.

Extreme weather events such as heat waves are becoming more frequent and severe, but most heat-related deaths are preventable with outreach and intervention, Dan Knecht, MD, vice president and chief clinical innovation officer for CVS Caremark, a division of CVS Health, said in an interview. The approach will combine the company’s services, including care managers, health centers, and data, to aid patients vulnerable to severe weather.

The initiative is starting with a focus on extreme heat events and will expand this fall with alerts about high levels of air pollution for individuals with vulnerability to reduced lung function, asthma, and cardiac problems as a result of exposure to high air-pollution levels, according to Dr. Knecht.

For now, the initiative is available to members of Aetna Medicare, according to Dr. Knecht. “Our goal is to expand to other consumers, including those who visit MinuteClinic and CVS Pharmacy locations, where we can provide timely environment-related recommendations at time of care,” he said.

The alert system uses environmental data analytics to pair highly localized forecasts and real-time insights about air quality, wildfires, and high heat with medical and pharmacy data for high-risk patients in areas affected by extreme weather.

For example, for individuals who are at risk and living in areas facing extreme heat, “registered nurse care managers proactively reach out to vulnerable patients up to several days in advance of an extreme weather event and provide them personalized tips and resources,” said Dr. Knecht.

In addition, he added, “we talk to patients about how to manage their medications during periods of extreme heat and, when delivering medications, take weather data into account to determine appropriate packaging materials for shipments.”

These interventions direct patients to CVS Health–linked resources, such as Oak Street Health clinics available as cooling centers, health services provided at MinuteClinic locations, and medication management at CVS pharmacies. Other interventions include virtual or in-person mental health counseling through MinuteClinic.

Dr. Knecht offered additional guidance for clinicians and patients to help manage heat waves. “Heat and certain medications can impair heat tolerance and the ability to regulate body temperature,” he told this news organization. Extreme heat may affect the performance of some medications and their devices, such as inhalers and diabetes supplies, he added.
 

Health Alerts Have Potential, But Comprehensive Approach is Needed

“Patients with chronic lung conditions are highly susceptible to the impact of climate change,” MeiLan K. Han, MD, a pulmonologist and professor of internal medicine at the University of Michigan, Ann Arbor, said in an interview. “Increasing dust, hotter temperatures, and higher levels of air pollution make it more difficult for patients to breathe,” she said. Data also suggest that higher levels of air pollution may not only cause chronic lung disease but also cause worsening symptoms among those with existing disease, she added.

A weather-related health alert could be useful for patients so they can be prepared, Dr. Han told this news organization.

“For a patient with chronic lung disease, a hot weather alert may mean that it will be harder for patients to breathe, and [they] may [be] more susceptible to heat stroke and dehydration if they do not have access to air conditioning,” she said. “At a minimum, patients should ensure they are on their controller medications, which often means a daily inhaler for patients with conditions such as asthma and chronic obstructive pulmonary disease (COPD). However, patients also should have access to their short-term reliever medications so they can be prepared for increased shortness of breath that may accompany a hot weather day,” Dr. Han explained.

However, not all patients have access to technology such as smartphones or other devices that will alert them to impending weather events, such as heat waves, said Dr. Han. “For these patients, a standard phone call may be beneficial,” she said.

Looking ahead, “programs for weather-related health alerts will need to be comprehensive, focusing not only on access to needed medications but also climate-controlled settings for temporary relief of heat,” said Dr. Han. “For some of our most vulnerable patients, while they may have air conditioning, they may not be able to afford to run it, so this needs to be considered in developing a comprehensive program,” she emphasized.

Dr. Knecht had no financial conflicts to disclose. Dr. Han disclosed ties with Aerogen, Altesa BioSciences, American Lung Association, Amgen, Apreo Health, AstraZeneca, Biodesix, Boehringer Ingelheim, Chiesi, Cipla, COPD Foundation, DevPro, Gala Therapeutics, Genentech, GlaxoSmithKline, Integrity, MDBriefcase, Medscape, Medtronic, Medwiz, Meissa Vaccines, Merck, Mylan, NACE, National Institutes of Health, Novartis, Nuvaira, Polarian, Pulmonx, Regeneron, Roche, RS Biotherapeutics, Sanofi, Sunovion, Teva, UpToDate, and Verona..

Looking ahead, “programs for weather-related health alerts will need to be comprehensive, focusing not only on access to needed medications but also climate-controlled settings for temporary relief of heat,” said Dr. Han. “For some of our most vulnerable patients, while they may have air conditioning, they may not be able to afford to run it, so this needs to be considered in developing a comprehensive program,” she emphasized.

As more data show potentially dangerous effects of climate and weather on individuals with chronic medical conditions, CVS Health has introduced an initiative that uses technology to provide weather alerts and targeted outreach to those at increased risk, according to a press release from the company. Ultimately, the goals of the initiative are to improve health, reduce emergency department visits, hospital stays, and medical costs, according to the press release.

Extreme weather events such as heat waves are becoming more frequent and severe, but most heat-related deaths are preventable with outreach and intervention, Dan Knecht, MD, vice president and chief clinical innovation officer for CVS Caremark, a division of CVS Health, said in an interview. The approach will combine the company’s services, including care managers, health centers, and data, to aid patients vulnerable to severe weather.

The initiative is starting with a focus on extreme heat events and will expand this fall with alerts about high levels of air pollution for individuals with vulnerability to reduced lung function, asthma, and cardiac problems as a result of exposure to high air-pollution levels, according to Dr. Knecht.

For now, the initiative is available to members of Aetna Medicare, according to Dr. Knecht. “Our goal is to expand to other consumers, including those who visit MinuteClinic and CVS Pharmacy locations, where we can provide timely environment-related recommendations at time of care,” he said.

The alert system uses environmental data analytics to pair highly localized forecasts and real-time insights about air quality, wildfires, and high heat with medical and pharmacy data for high-risk patients in areas affected by extreme weather.

For example, for individuals who are at risk and living in areas facing extreme heat, “registered nurse care managers proactively reach out to vulnerable patients up to several days in advance of an extreme weather event and provide them personalized tips and resources,” said Dr. Knecht.

In addition, he added, “we talk to patients about how to manage their medications during periods of extreme heat and, when delivering medications, take weather data into account to determine appropriate packaging materials for shipments.”

These interventions direct patients to CVS Health–linked resources, such as Oak Street Health clinics available as cooling centers, health services provided at MinuteClinic locations, and medication management at CVS pharmacies. Other interventions include virtual or in-person mental health counseling through MinuteClinic.

Dr. Knecht offered additional guidance for clinicians and patients to help manage heat waves. “Heat and certain medications can impair heat tolerance and the ability to regulate body temperature,” he told this news organization. Extreme heat may affect the performance of some medications and their devices, such as inhalers and diabetes supplies, he added.
 

Health Alerts Have Potential, But Comprehensive Approach is Needed

“Patients with chronic lung conditions are highly susceptible to the impact of climate change,” MeiLan K. Han, MD, a pulmonologist and professor of internal medicine at the University of Michigan, Ann Arbor, said in an interview. “Increasing dust, hotter temperatures, and higher levels of air pollution make it more difficult for patients to breathe,” she said. Data also suggest that higher levels of air pollution may not only cause chronic lung disease but also cause worsening symptoms among those with existing disease, she added.

A weather-related health alert could be useful for patients so they can be prepared, Dr. Han told this news organization.

“For a patient with chronic lung disease, a hot weather alert may mean that it will be harder for patients to breathe, and [they] may [be] more susceptible to heat stroke and dehydration if they do not have access to air conditioning,” she said. “At a minimum, patients should ensure they are on their controller medications, which often means a daily inhaler for patients with conditions such as asthma and chronic obstructive pulmonary disease (COPD). However, patients also should have access to their short-term reliever medications so they can be prepared for increased shortness of breath that may accompany a hot weather day,” Dr. Han explained.

However, not all patients have access to technology such as smartphones or other devices that will alert them to impending weather events, such as heat waves, said Dr. Han. “For these patients, a standard phone call may be beneficial,” she said.

Looking ahead, “programs for weather-related health alerts will need to be comprehensive, focusing not only on access to needed medications but also climate-controlled settings for temporary relief of heat,” said Dr. Han. “For some of our most vulnerable patients, while they may have air conditioning, they may not be able to afford to run it, so this needs to be considered in developing a comprehensive program,” she emphasized.

In the case of a hip fracture, operating on a patient with dementia can be a difficult decision to make. Indeed, surgery exposes patients with dementia to a higher mortality rate, more delirium and postoperative complications, and a greater loss of mobility than patients of the same age without cognitive impairments. For patients with dementia in institutional settings, survival is better for those who undergo surgery than for those who do not. But what about the prognosis of surgery vs no surgery for patients with dementia who live at home?

To answer this question, researchers in the United States conducted a cohort study using Medicare data. This retrospective study included patients aged 66 years and older with dementia who were living at home and not placed in institutions and who had a hip fracture between January 2017 and June 2018. Patients with incomplete observations, particularly regarding the location and type of residence (home/institution), were excluded from the analysis. Fractures were categorized as (i) fractures of the head and neck, (ii) pertrochanteric, (iii) subtrochanteric, and (iv) multiple/complex. The type and severity (mild, moderate, or severe) of dementia were identified using the diagnostic code list in the International Statistical Classification of Diseases, Tenth Revision.
 

Examining Mortality

The primary outcome was mortality at 30, 90, and 180 days. Secondary outcomes included hospital delirium; the need for subsequent hospitalization (within 6 months) or home health services (within 10 days); and intensive care interventions such as dialysis, intubation, resuscitation maneuvers, mechanical ventilation, or the insertion of a feeding tube.

Postoperative medical facility admissions were distinguished according to whether there was a plan to return home. To compare the surgery and nonsurgery groups, an inverse propensity score analysis was conducted within subgroups determined by fracture type, comorbidities (using the Elixhauser score), the person or entity responsible for admission (ie, physician, clinic, hospital, etc.), dual eligibility (Medicare and Medicaid), place of residence (ie, urban or rural), race, and sex. Dementia severity was estimated using a frailty index on the basis of evaluation tests that were systematically collected in the Medicare database.
 

Results Favored Surgery

Among 56,209 patients with dementia who were admitted for a hip fracture (73.0% women; mean age, 86.4 ± 7.0 years), 33,142 (59.0%) underwent surgery and 23,067 (41.0%) did not. Among surgically treated patients, 73.3% had fractures of the head or neck of the femur, and 40.2% had moderate to severe dementia. The nonsurgically treated fractures were 78.5% pertrochanteric. Comorbidities were evenly distributed between the two groups.

At 180 days, mortality was 31.8% in the surgery group compared with 45.7% in the nonsurgery group, resulting in a significant reduction in the unadjusted relative risk (RR) for death in favor of surgery (RR, 0.67; 95% CI, 0.60-0.76; P < .001). Among patients with mild dementia and a fracture of the head or neck of the femur, mortality at 180 days was 26.5% among surgical patients and 34.9% among nonsurgical patients (RR, 0.67; 95% CI, 0.60-0.76; P < .001). After the investigators adjusted for risk according to propensity score, the benefit of surgery remained significant at 30, 90, and 180 days, regardless of dementia severity. There was no significant difference in mortality for other types of hip fractures between the surgery and nonsurgery groups, however.

The adjusted RR for in-hospital delirium was 1.23 (P = .008), which was significant for the surgery group, but only for those with moderate to severe dementia. There were also fewer permanent placements (P < .001) among the surgically treated patients, and fewer patients with mild dementia required nurse care at home. There was no difference in resuscitation maneuvers between surgery and nonsurgery patients, whether the dementia was mild or not. For patients with a fracture of the head or neck of the femur, there was no difference in the likelihood of rehabilitation admission within 180 days, whether they were operated on or not.
 

Ethical Considerations

This study can inform discussions among healthcare professionals, patients, and patients’ families about which goals to set and which strategy to choose. The main interest of this study lies in its comparison of outcomes between patients with dementia who were operated on and those who were not, rather than comparing patients with and without dementia. Among patients with dementia living at home with a fracture of the head or neck of the femur, those who underwent surgery had a lower risk for death than those who did not, regardless of the severity of dementia.

It is noteworthy that less than two thirds of patients with dementia underwent surgery, which contradicts recommendations for almost routine surgery for patients with dementia. This observation raises questions about respecting patient wishes and advance directives when known, possible detrimental delays in referrals, and legal-medical issues.

Furthermore, the treatment choices of American surgeons are clearly influenced by the type of hip fracture. Fractures of the head and neck of the femur are typically treated with prosthetic arthroplasty, which simplifies postoperative care, compared with osteosynthesis. The latter procedure is more often used for extra-articular hip fractures but entails higher risks. While survival is an apparently more easily achievable goal through surgery, ethical considerations about other treatment objectives such as pain control, functional recovery, and treatment adequacy cannot be overlooked. It is worth noting that the French National Authority for Health issued recommendations in 2018 regarding the care pathway for patients hospitalized for a hip fracture within an orthogeriatric organization.

Primary care physicians know the complexities of treating older patients, from increased complications from medications and procedures to comorbidities stemming from having multiple medical conditions. The Beers Criteria were established by the American Geriatrics Society as a guide for physicians about medications that may possess more risks than benefits in older patients, specifically those aged 65 years and older.

There are approximately 100 medications on the list. Criteria used to establish the list include medications to avoid over the age of 65 in an outpatient setting, medications to avoid in certain medical conditions, medications to avoid that may interact with other medications, medications to avoid with renal impairment, and medications to avoid where harmful side effects outweigh the possible benefits. The American Geriatrics Society updates the list as new published evidence becomes available.

The latest updates to the Beers Criteria include several medications commonly used in primary care. Regarding anticoagulation, warfarin should be avoided as initial therapy and apixaban should be used in patients with reduced renal function. These guidelines looked particularly at antithrombotic medications because of new evidence arising in nonvalvular atrial fibrillation and venous thromboembolism. In addition to the previous recommendations, the use of aspirin is no longer recommended in older adults.

The latest guidelines also make recommendations regarding certain diabetic medications as well as combinations to avoid. The Beers Criteria now place all sulfonylureas in the class to avoid, and not just the long-acting formulations as was recommended in the previous guidelines. If a sulfonylurea is necessary, use of a short-acting one is advised. Several other classes of medications were addressed and doctors practicing primary care medicine should be aware of these guidelines, especially as the population continues to age.

Overall, these guidelines are a great resource for treating patients aged 65 and older. It is important to keep in mind that they look at a whole population of patients and it is not patient specific. As primary care doctors, we know many of our patients don’t fit into the textbook box. While these guidelines consider the dangers of a certain medication, sometimes the benefits do outweigh the risks at the patient-specific level.

As doctors, we are trained to weigh the risks and benefits when prescribing any medication to our patients. These guidelines shouldn’t be approached as a do or don’t list but should be considered in the overall plan when prescribing for our patients. Sometimes, these medications can be used with careful observation by the prescribing physician. When they are utilized, we need to make the patient aware of specific side effects and what to watch out for. We need to make these decisions together with our patients and their caregivers.

For example, we all know how agonizing taking care of an older dementia patient can be, and sometimes there is nothing left to try except one of the medications on the list.

An additional practical point not considered in the guidelines is real-world use. Often, certain medications are not covered by a patient’s insurance company. The cost can be prohibitive to use the recommended agent. We are left in the middle to go off script with a medication that the patient may be able to access easily or keep pushing for the most appropriate medication for the patient. Unfortunately, in our current healthcare climate, prior authorizations can sometimes take weeks to obtain (or to be denied). For most of the conditions we treat in our older patients, it is not safe to leave them without any medication while we fight this prior authorizations war.

Our older patients often have multiple specialists as well. Each of these specialists may be prescribing different medications. It is imperative that we know all the medications a patient is taking so that we may look for potentially dangerous drug interactions. Many patients don’t remember the names of all their medications, nor do they realize that many classes of medications are “little white pills.” Asking them to bring their pill bottles to every visit can be a great help in searching out interactions.

That being said, the Beers Criteria do an excellent job reviewing the latest evidence and developing guidelines. As primary care physicians, we have never been busier and having someone do the research and set it forth so clearly is a great tool. We should be aware of the Beers Criteria and the medications and interactions listed there.

For example, we all know how agonizing taking care of an older dementia patient can be, and sometimes there is nothing left to try except one of the medications on the list.

An additional practical point not considered in the guidelines is real-world use. Often, certain medications are not covered by a patient’s insurance company. The cost can be prohibitive to use the recommended agent. We are left in the middle to go off script with a medication that the patient may be able to access easily or keep pushing for the most appropriate medication for the patient. Unfortunately, in our current healthcare climate, prior authorizations can sometimes take weeks to obtain (or to be denied). For most of the conditions we treat in our older patients, it is not safe to leave them without any medication while we fight this prior authorizations war.

Our older patients often have multiple specialists as well. Each of these specialists may be prescribing different medications. It is imperative that we know all the medications a patient is taking so that we may look for potentially dangerous drug interactions. Many patients don’t remember the names of all their medications, nor do they realize that many classes of medications are “little white pills.” Asking them to bring their pill bottles to every visit can be a great help in searching out interactions.

That being said, the Beers Criteria do an excellent job reviewing the latest evidence and developing guidelines. As primary care physicians, we have never been busier and having someone do the research and set it forth so clearly is a great tool. We should be aware of the Beers Criteria and the medications and interactions listed there.

People over age 60 who drink alcohol regularly are at an increased risk of early death, particularly from cancer or issues related to the heart and blood vessels.

That’s according to the findings of a new, large study that was published in JAMA Network Openand build upon numerous other recent studies concluding that any amount of alcohol consumption is linked to significant health risks. That’s a change from decades of public health messaging suggesting that moderate alcohol intake (one or two drinks per day) wasn’t dangerous. Recently, experts have uncovered flaws in how researchers came to those earlier conclusions.

In this latest study, researchers in Spain analyzed health data for more than 135,000 people, all of whom were at least 60 years old, lived in the United Kingdom, and provided their health information to the UK Biobank database. The average age of people at the start of the analysis period was 64.

The researchers compared 12 years of health outcomes for occasional drinkers with those who averaged drinking at least some alcohol on a daily basis. The greatest health risks were seen between occasional drinkers and those whom the researchers labeled “high risk.” Occasional drinkers had less than about two drinks per week. The high-risk group included men who averaged nearly three drinks per day or more, and women who averaged about a drink and a half per day or more. The analysis showed that, compared with occasional drinking, high-risk drinking was linked to a 33% increased risk of early death, a 39% increased risk of dying from cancer, and a 21% increased risk of dying from problems with the heart and blood vessels.

More moderate drinking habits were also linked to an increased risk of early death and dying from cancer, and even just averaging about one drink or less daily was associated with an 11% higher risk of dying from cancer. Low and moderate drinkers were most at risk if they also had health problems or experienced socioeconomic factors like living in less affluent neighborhoods.

The findings also suggested the potential that mostly drinking wine, or drinking mostly with meals, may be lower risk, but the researchers called for further study on those topics since “it may mostly reflect the effect of healthier lifestyles, slower alcohol absorption, or nonalcoholic components of beverages.”

A recent Gallup poll showed that overall, Americans’ attitudes toward the health impacts of alcohol are changing, with 65% of young adults (ages 18-34) saying that drinking can have negative health effects. But just 39% of adults age 55 or older agreed that drinking is bad for a person’s health. The gap in perspectives between younger and older adults about drinking is the largest on record, Gallup reported.

The study investigators reported no conflicts of interest.

Poorer physical function, not poorer bone mineral density (BMD), could be the principal reason for the increased fracture risk in older women with type 2 diabetes (T2D), according to a Swedish prospective observational study in JAMA Network Open.

The study was conducted in more than 3000 Swedish women by Mattias Lorentzon, MD, a professor of geriatric medicine at Gothenburg University, and chief physician at the Osteoporosis Clinic at Sahlgrenska University Hospital in Mölndal, and colleagues.

Study Details

A fractures study was performed in the Gothenburg area from March 2013 to May 2016 with follow-up of incident fracture data completed in March 2023. Data were collected from questionnaires and through examination of anthropometrics, physical function, and bone measurements using dual-energy x-ray absorptiometry and high-resolution peripheral computed tomography. A subsample underwent bone microindentation to assess BMSi.

Among the cohort’s 3008 women, ages 75-80 (mean, 77.8), 294 patients with T2D were compared with 2714 same-age unaffected women.

During a median follow-up of 7.3 years, 1071 incident fractures, 853 major osteoporotic fractures, and 232 hip fractures occurred. In models adjusted for age, BMI, clinical risk factors, and femoral neck BMD, T2D was associated with an increased risk of any fracture: hazard ratio (HR), 1.26; (95% CI, 1.04-1.54), and major osteoporotic fracture (HR, 1.25; 95% CI, 1.00-1.56).

Most fractures were due to falls, with the most common affected sites being the forearm, upper arm, spine, and hip, Dr. Lorentzon said.

Among the findings:

• In bone microarchitecture, women with T2D had higher BMD at all sites: total hip, 4.4% higher; femoral neck, 4.9% higher; and lumbar spine, 5.2% higher.
• At the tibia, the T2D group had 7.4% greater cortical area and 1.3% greater density, as well as 8.7% higher trabecular bone volume fraction.

“Our findings regarding BMD are consistent with previous publications showing higher BMD in individuals with T2D compared with those without diabetes,” Dr. Lorentzon said. A 2012 meta-analysis, for example, showed higher BMD levels in T2D patients. “Some smaller studies, however, have found worse bone microstructure and lower bone material strength in contrast to the results from our study,” Dr. Lorentzon said.

• There was no difference in BMSi, with a mean of 78 in both groups.
• The T2D group had lower performance on all physical function tests: a 9.7% lower grip strength, 9.9% slower gait speed, and 13.9% slower timed up-and-go time than women without diabetes.

“We found all parameters regarding physical function, such as muscle strength, balance, and performance, were much worse in women with diabetes than in those without,” Dr. Lorentzon said. “Dizziness could also be a contributor to the increased risk of falls, but this factor was not investigated in our study.”

Commenting on the study but not involved in it, Anthony J. Pick, MD, an endocrinologist at Northwestern Medicine Lake Forest Hospital in Lake Forest, Illinois, said sarcopenia is a common and often under-recognized problem in older adults and is especially prevalent in T2D, obesity, and heart failure. “I believe that ‘exercise is medicine’ is a key concept for metabolic and osteoporosis patients — and wellness and longevity in general — and I certainly hope studies like this drive awareness of the importance of engaging in strengthening exercises.”

What if a drug could help you live a longer, healthier life?

Scientists at the University of Connecticut are working on it. In a new study in Cell Metabolism, researchers described how to target specific cells to extend the lifespan and improve the health of mice late in life.

The study builds on a growing body of research, mostly in animals, testing interventions to slow aging and prolong health span, the length of time that one is not just alive but also healthy.

“Aging is the most important risk factor for every disease that we deal with in adult human beings,” said cardiologist Douglas Vaughan, MD, director of the Potocsnak Longevity Institute at Northwestern University’s Feinberg School of Medicine, Chicago. (Dr. Vaughan was not involved in the new study.) “So the big hypothesis is: If we could slow down aging just a little bit, we can push back the onset of disease.”

As we age, our cells wear out. It’s called cellular senescence — a state of irreversible cell cycle arrest — and it’s increasingly recognized as a key contributor to aging.

Senescent cells — or “zombie cells” — secrete harmful substances that disrupt tissue functioning. They’ve been linked to chronic inflammation, tissue damage, and the development of age-related diseases.

Senescence can be characterized by the accumulation of cells with high levels of specific markers like p21, or p21^high cells. Almost any cell can become a p21^high cell, and they accumulate with age, said Ming Xu, PhD, a professor at the UConn Center on Aging, UConn Health, Farmington, Connecticut, who led the study.

By targeting and eliminating p21^high senescent cells, Dr. Xu hopes to develop novel therapies that might help people live longer and enjoy more years in good health.

Such a treatment could be ready for human trials in 2-5 years, Dr. Xu said.
 

What the Researchers Did

Xu and colleagues used genetic engineering to eliminate p21^high cells in mice, introducing into their genome something they describe as an inducible “suicide gene.” Giving the mice a certain drug (a low dose of tamoxifen) activated the suicide gene in all p21^high cells, causing them to die. Administering this treatment once a month, from age 20 months (older age) until the end of life, significantly extended the rodents’ lifespan, reduced inflammation, and decreased gene activity linked to aging.

Treated mice lived, on average, for 33 months — 3 months longer than the untreated mice. The oldest treated mouse lived to 43 months — roughly 130 in human years.

But the treated mice didn’t just live longer; they were also healthier. In humans, walking speed and grip strength can be clues of overall health and vitality. The old, treated mice were able to walk faster and grip objects with greater strength than untreated mice of the same age.

Dr. Xu’s lab is now testing drugs that target p21^high cells in hopes of finding one that would work in humans. Leveraging immunotherapy technology to target these cells could be another option, Dr. Xu said.

The team also plans to test whether eliminating p21^high cells could prevent or alleviate diabetes or Alzheimer’s disease.
 

Challenges and Criticisms

The research provides “important evidence that targeting senescence and the molecular components of that pathway might provide some benefit in the long term,” Dr. Vaughan said.

But killing senescent cells could come with downsides.

“Senescence protects us from hyperproliferative responses,” potentially blocking cells from becoming malignant, Dr. Vaughan said. “There’s this effect on aging that is desirable, but at the same time, you may enhance your risk of cancer or malignancy or excessive proliferation in some cells.”

And of course, we don’t necessarily need drugs to prolong healthy life, Dr. Vaughan pointed out.

For many people, a long healthy life is already within reach. Humans live longer on average than they used to, and simple lifestyle choices — nourishing your body well, staying active, and maintaining a healthy weight — can increase one’s chances of good health.

The most consistently demonstrated intervention for extending lifespan “in almost every animal species is caloric restriction,” Dr. Vaughan said. (Dr. Xu’s team is also investigating whether fasting and exercise can lead to a decrease in p21^high cells.)

As for brain health, Dr. Vaughan and colleagues at Northwestern are studying “super agers,” people who are cognitively intact into their 90s.

“The one single thing that they found that contributes to that process, and contributes to that success, is really a social network and human bonds and interaction,” Dr. Vaughan said.
