ACIP favors shared decision on pneumococcal vaccine for older adults
Pneumococcal vaccination with the 13-valent pneumococcal conjugate vaccine (PCV13) based on shared clinical decision making is recommended for immunocompetent adults aged 65 years and older who have not previously received PCV13, and all adults aged 65 years and older should continue to receive the pneumococcal polysaccharide vaccine (PPSV23), according to a vote at a meeting of the Centers for Disease Control and Prevention’s Advisory Committee on Immunization Practices.
The motion passed with an 11-1 vote after members voted down two other options to either discontinue or continue the current recommendation of PCV13 for all immunocompetent adults aged 65 years and older. The current recommendation for PCV13 for adults aged 65 years and older has been in place since 2014.
The pneumococcal work group assessed indirect effects of the pediatric PCV vaccination on older adults prior to 2014 and since 2014, and what additional benefits might be expected if routine vaccination of older adults continued.
“Indirect effects have been observed in all age groups” said Almea Matanock, MD, of the CDC’s National Center for Immunization and Respiratory Diseases. Although there were no safety concerns, the public health impact of continued vaccination of adults was minimal.
Although PCV13 resulted in a 75% reduction in vaccine-type invasive pneumococcal disease and a 45% reduction in vaccine-type nonbacteremic pneumonia in 2014, the annual number needed to vaccinate to prevent a single case of outpatient pneumonia was 2,600, said Dr. Matanock.
Dr. Matanock presented key issues from the Evidence to Recommendations Framework for and against the recommendation for PCV13 in older adults. Work group comments in favor of continuing the recommendation for PCV13 in older adults included effective disease prevention and the potential negative impact on the importance of adult vaccines if the vaccine was no longer recommended. However, some work group members and committee members expressed concern about resource allocation and steering vaccines away from younger age groups in whom they have been more consistently effective.
Paul Hunter, MD, of the City of Milwaukee Health Department, voted against the shared clinical decision making, and instead favored discontinuing the recommendation for PCV13 for older adults. “I think clinicians need a clear message,” he said, adding that “the public health bang for the buck is with the kids.”
“I think there was a recognition that the population level benefit is minimal,” said work group chair Grace Lee, MD.
Although the work group recognized some benefit for older adults, the burden of disease for PCV-specific disease is low, compared with all-cause pneumonia, said Dr. Lee of Lucile Packard Children’s Hospital at Stanford, Calif. However, the recommendation for shared clinical decision making allows for potential insurance coverage of the vaccine for adults who decide after discussion with their health care provider that they would benefit.
“We are still unpacking this construct” of shared clinical decision making, which in this case applies to adults without immunocompromising conditions, and is more of a provider assessment than a risk assessment, she said.
The ACIP members had no financial conflicts to disclose.

Anticholinergic drugs linked to dementia in older populations
Exposures to various types of anticholinergic medications were associated with a significantly increased risk of dementia in people aged 55 years or older in a large pharmacoepidemiologic study.
“This study was designed to assess the association between cumulative anticholinergic drug use and risk of dementia in a large, representative British population,” wrote Carol A. C. Coupland, PhD, of the division of primary care at the University of Nottingham (England), and colleagues. The findings were published in JAMA Internal Medicine.
The researchers conducted a large nested case-control study that included 58,769 patients with dementia and 225,574 matched controls from the QResearch database in England. Each study participant was matched to five controls based on various characteristics, including sex, age, and calendar time, among others.
Prescription data related to 56 different drugs with strong anticholinergic properties, including antipsychotics, bladder antimuscarinics, antiepileptics, antiparkinson agents, and antidepressants were used to measure drug exposure. The study data were analyzed from 2016 to 2018.
“The primary exposure was the total standardized daily doses (TSDDs) of anticholinergic drugs prescribed in the 1 to 11 years prior to the date of diagnosis of dementia or equivalent date in matched controls,” Dr. Coupland and colleagues wrote.
After analysis, the researchers found that exposure to antipsychotics (adjusted odds ratio, 1.70), bladder antimuscarinics (aOR, 1.65), antiepileptics (aOR, 1.39), antiparkinson agents (aOR, 1.52), and anticholinergic antidepressants (aOR, 1.29) was associated with an increased risk of dementia after adjustment for confounding factors.
“Associations were stronger in [dementia] cases diagnosed before the age of 80 years,” the researchers noted.
However, antihistamine, antivertigo/antiemetic, skeletal muscle relaxant, gastrointestinal antispasmodic, antiarrhythmic, and antimuscarinic bronchodilator anticholinergic agents were not associated with any increased risk of dementia.
One key limitation of the study was the absence of medication compliance assessment, which could result in exposure misclassification. Dr. Coupland and colleagues acknowledged this could underestimate some associations with medication exposure.
The stronger risk of dementia found among people who had dementia before age 80 “indicates that anticholinergic drugs should be prescribed with caution in middle-aged and older people,” they concluded.
One question that remains from the current study is whether anticholinergic drugs are a definite modifiable risk factor for Alzheimer’s disease and related dementias, Noll L. Campbell, PharmD, of Purdue University, West Lafayette, Ind., and colleagues wrote in an editorial accompanying the study by Dr. Coupland and associates (JAMA Intern Med. 2019 Jun 24. doi: 10.1001/jamainternmed.2019.0676).
While a pharmacologic basis for this association has been proposed, causation has yet to be established by means of prospective randomized studies. The current supposition is that deprescribing anticholinergic medications has the potential to positively effect cholinergic neurotransmission in certain regions of the brain, which could lead to improved cognitive functioning, and lower the likelihood of developing Alzheimer’s disease and related dementias, they wrote in the editorial.
However, the discontinuation of some anticholinergic agents may pose other risks, such as worsening pain or depressive symptoms, in addition to increasing the utilization of acute care facilities. As a result, high-quality, well-designed, randomized trials are needed to better understand the long-term effects of deprescribing anticholinergic medications. These trials would help inform clinicians, patients, and policymakers about the risks and benefits of deprescribing interventions, Dr. Campbell and coauthors said.

Levothyroxine did not reduce fatigue in older patients with hypothyroidism
WASHINGTON – according to a new study.
The double-blind, randomized, placebo-controlled, parallel-group trial used subsets of data from the TRUST study. This new research, which was presented at the Annual Meeting of the Society of General Internal Medicine, provides further evidence that prescribing levothyroxine to older patients with subclinical hypothyroidism will not reduce fatigue.
Like the findings in the TRUST study, the new study, “Effect of Thyroid Hormone Replacement on Fatigability in Older Adults with Subclinical Hypothyroidism: A Randomized Placebo Controlled Trial,” showed that the use of levothyroxine in subclinical hypothyroidism was not effective in changing physical and mental fatigability in older adults.
“This study shows that levothyroxine treatment may not be necessary and results in high costs and side effects,” noted Mirah Stuber, MD, during her presentation of the findings at the meeting.
The new study examined the effect of levothyroxine on the tiredness of older adults but with a more detailed analysis of fatigue than the full TRUST study provided. In this new study, investigators used a new assessment tool, called the Pittsburgh Fatigability Scale (PFS), a 10-item self-administered questionnaire that can measure both physical and mental fatigability. Perceived fatigability anchors tiredness to a set of activities and has been shown to be a more sensitive measure than global fatigue, explained Dr. Stuber of the University of Chicago.
The scores range from 0-50, with higher scores indicating higher fatigability. The scales were divided between mental and physical activities and measured fatigue in relation to a defined activity of a specific duration and intensity. These activities included a leisurely 30-minute walk and participation in a 1-hour social activity.
This study involved 230 participants from Switzerland and Ireland, with a mean age of 73.4 years, who had persistent hypothyroidism. The population was randomized to 119 patients who were administered levothyroxine and 111 patients who received a placebo.
At baseline, the levothyroxine group had a mean physical PFS score of 14.7 ± 9.3, and the placebo group had a score of 11.1 ± 9.1. The baseline mean mental PFS score for the levothyroxine group was 7.4 ± 8.0, while it was 5.1 ± 6.9 for the placebo group.
After 12 months of the participants’ use of levothyroxine or placebo, the physical PFS scores increased for both the treatment and placebo groups. For the levothyroxine group, the mean physical PFS score was 14.8 ± 9.6, while it was 12.4 ± 9.3 for the placebo group (P = 0.88). The investigators found no significant differences between these scores for the levothyroxine and placebo groups.
The mean mental PFS score slightly decreased to 6.0 ± 7.8 for the levothyroxine group, while it slightly increased to 6.0 ± 8.0 for the placebo group (P = 0.26) at 12 months. The difference between the mental fatigability scores for the levothyroxine and placebo arms at 12 months was also not significant.
The physical fatigability between-group difference was 0.2 (95% confidence interval, –1.8 to 2.1; P = 0.88), while the mental fatigability difference was –1.0 (95% CI, –2.8 to 0.8; P = 0.26).
The study was funded by the European Union FP7 and the Swiss National Science Foundation. Merck KGaA, Darmstadt (Germany) provided levothyroxine and the placebo. Dr. Stuber has no conflicts of interest.

REPORTING FROM SGIM 2019
A/T/N system predicts cognitive decline
Adding the amyloid/tau/neurodegeneration (A/T/N) model of dementia to a clinical model may give an incremental but still significantly increased ability to predict cognitive decline over nearly 5 years, according to findings from a longitudinal cohort study of patients without dementia at baseline.
Although the A/T/N model is still intended only for research purposes, the study came to another important conclusion: About 50% of the memory change associated with normal aging was, in fact, caused by changes associated with Alzheimer’s disease, Clifford R. Jack Jr., MD, and colleagues wrote in JAMA.
The three groups with the fastest rates of memory decline all had abnormal amyloid and either abnormal tau and/or imaging signs of neurodegeneration. “This illustrated a dominant association of memory decline with amyloidosis but only when present in combination with tauopathy, neurodegeneration, or both,” Dr. Jack of the Mayo Clinic, Rochester, Minn., and coauthors wrote.
A/T/N, also known as the National Institute on Aging and Alzheimer’s Association Research Framework, is based on objective amyloid and tau biomarkers and imaging markers of neurodegeneration and is intended to more accurately differentiate Alzheimer’s from other dementias and, potentially, to stage the disease and predict and track decline. It generates eight clinical profiles that can identify Alzheimer’s, rule it out, or include it as a possible diagnosis.
The study comprised 480 elderly individuals enrolled in the Mayo Clinic Study on Aging. Median age of the participants ranged from 67 years in one of the eight clinical profiles (A–/T–/N–) to 83 years in another (A+/T+/N+). Most (92%) were cognitively normal; the remainder had mild cognitive impairment (MCI). They were followed for a median of 4.8 years.
Both amyloid and tau were measured with PET imaging; neuropathology was represented by MRI scans of cortical thickness. Most (n = 140) were negative for all biomarkers (A–/T–/N–). The group positive for all markers (A+/T+/N+) had the largest proportion of MCI subjects (30%). The apolipoprotein E epsilon 4 (APOE4) genotype was more common among the A+ groups than it was among the A– groups (40% vs. 21%).
The individual cognitive decline trajectories varied considerably by age and within each classification group. Only 7% of the A–/T–/N– group were 80 years or older, and only 2% of the A+/N+/T+ group were younger than 70 years.
In a clinical model, age and APOE4 status were significantly associated with faster rates of memory decline. Sex, education, and a cardiovascular/metabolic model were not, however.
“The estimated rate of memory decline in a 75-year-old individual who was an APOE4 noncarrier was –0.04 z-score units per year,” the authors wrote. “An 85-year-old individual who was also an APOE4 noncarrier could be expected to have a decline of –0.08 units per year, while a 75-year-old E4 carrier could be expected to have a decline of –0.08 units per year.”
Every 10 years of additional age was associated with a significant median worsening of 0.4 on z score for memory. A 4-year difference in education was associated with a 0.6-unit higher memory score, while APOE4 carriers had a 0.3-unit lower memory score.
The addition of the A/T/N model significantly improved the prediction of cognitive decline and memory score, although the rates of decline were still considerably variable. All of the A+ groups had the fastest decline rates.
“To place the predictive utility of biomarkers in clinical context, the decline in rates of memory for A+/T+/N–, A+/T–/N+, A+/T+/N+ [abnormal amyloid plus tau or neurodegeneration] were of similar magnitude to a 20-year increase in age and were twice that associated with APOE4 carriership,” they wrote.
A total of 88 participants had a second imaging visit at a median of 15 months. Most (n = 72) had no change in the A/T/N classification. A and T classifications were more stable (98% and 97%, respectively) than was N classification (84%).
A secondary analysis compared this model with generally accepted clinical and biomarker characteristics. Prior research has shown that prevalence of abnormal A/T/N biomarker groups increased with age in the Mayo Clinic Study on Aging. The mean annual memory z-score in this cohort at 60 years was 0.02, which dropped to 0.11 by age 90.
“Forty-six percent of this increase in decline rate [–0.06] was partitioned to the increasing prevalence of abnormal A/T/N profiles, while the remaining decline [–0.07] was partitioned to age,” the investigators reported.
While A+ subjects were most likely to decline, the A+/T–/N+ group presents a conundrum, the team wrote. “A possible explanation is that these individuals have early Alzheimer’s disease [denoted by A+T–] plus neurodegeneration due to comorbid non–Alzheimer’s disease neuropathic changes.”
This is an important point because the cognitive decline of Alzheimer’s is thought to be largely associated with tauopathy, not amyloidosis. “One possible explanation is an effect of subthreshold tau in A+/T–/N+ individuals, but this is speculative. Clearer understanding of the neuropathologic bases for the A+/T–/N+ group, as well as other A/T/N groups, awaits future biomarker-autopsy correlation studies.”

The findings reported by Jack et al. most immediately affect research cohorts, but they raise an interesting suggestion: Only in the presence of concomitant tau, neuropathology, or both does amyloidosis appear related to an increased rate of cognitive decline when compared with non-Alzheimer’s groups.
Prevention studies lasting only a few years may be more likely to find treatment effects on disease progression in actively treated groups of those patients.
An interesting finding in the study is that A+/T–/N+ subjects showed faster rates of cognitive decline than did the A–/T–/N+ groups even though, in both cases, neurodegeneration is thought to be driven by non-Alzheimer’s pathology. What is causing disease in the A–/T–/N+ group will be unclear until the framework is enriched with other important contributors to age-related cognitive decline.
Currently, A/T/N classification – based on neuroimaging – is costly and impractical on a large scale, and so far lacks data on the added value of each specific A/T/N measure and generalizability to more diverse patient populations.
Despite these concerns, the study by Jack et al. represents an important contribution in conceptualizing Alzheimer’s disease and testing the research framework in a relatively large sample of participants.

Adding the amyloid/tau/neurodegeneration (A/T/N) model of dementia to a clinical model may give an incremental but still significantly increased ability to predict cognitive decline over nearly 5 years, according to findings from a longitudinal cohort study of patients without dementia at baseline.
Although the A/T/N model is still intended only for research purposes, the study came to another important conclusion: About 50% of the memory change associated with normal aging was, in fact, caused by changes associated with Alzheimer’s disease, Clifford R. Jack Jr., MD, and colleagues wrote in JAMA.
The three groups with the fastest rates of memory decline all had abnormal amyloid and either abnormal tau and/or imaging signs of neurodegeneration. “This illustrated a dominant association of memory decline with amyloidosis but only when present in combination with tauopathy, neurodegeneration, or both,” Dr. Jack of the Mayo Clinic, Rochester, Minn., and coauthors wrote.
A/T/N, also known as the National Institute on Aging and Alzheimer’s Association Research Framework, is based on objective amyloid and tau biomarkers and imaging markers of neurodegeneration and is intended to more accurately differentiate Alzheimer’s from other dementias and, potentially, to stage the disease and predict and track decline. It generates eight clinical profiles that can identify Alzheimer’s, rule it out, or include it as a possible diagnosis.
The study comprised 480 elderly individuals enrolled in the Mayo Clinic Study on Aging. Median age of the participants ranged from 67 years in one of the eight clinical profiles (A–/T–/N–) to 83 years in another (A+/T+/N+). Most (92%) were cognitively normal; the remainder had mild cognitive impairment (MCI). They were followed for a median of 4.8 years.
Both amyloid and tau were measured with PET imaging; neuropathology was represented by MRI scans of cortical thickness. Most (n = 140) were negative for all biomarkers (A–/T–/N–). The group positive for all markers (A+/T+/N+) had the largest proportion of MCI subjects (30%). The apolipoprotein E epsilon 4 (APOE4) genotype was more common among the A+ groups than it was among the A– groups (40% vs. 21%).

Malnutrition leads to worse outcomes in frail elderly patients treated for PAD
Frailty increasingly has been seen as a factor in procedural outcomes, including vascular surgery. Nutrition factors among older adults have also become an issue of concern, and older adults undergoing interventions for peripheral arterial disease (PAD) may be at risk for malnutrition. At the Vascular Annual Meeting, Laura Drudi, MD, of McGill University, Montreal, reported on a study that she and her colleagues performed to determine the association between preprocedural nutritional status and all-cause mortality in patients being treated for PAD.
Dr. Drudi detailed their post hoc analysis of the FRAILED (Frailty Assessment in Lower Extremity arterial Disease) prospective cohort, which comprised two centers recruiting patients during July 1, 2015–Oct.1, 2016. Individuals who underwent vascular interventions for Rutherford class 3 or higher PAD were enrolled. Trained observers used the Mini Nutritional Assessment (MNA)–Short Form to assess the patients before their procedures. Scores less than or equal to 7 on a 14-point scale were considered malnourished, with scores of 8-11 indicated that patients were at risk for malnutrition.
The modified Essential Frailty Toolset (mEFT) was simultaneously used to measure frailty, with scores of 3 or less on a 5-point scale considered frail. The primary endpoint of the study was all-cause mortality at 12 months after the procedure. Results were available for a cohort of 148 patients (39.2% women) with a mean age of 70 years, and a mean body mass index of 26.7 kg/m2. Among these patients, 59 (40%) had claudication and 89 (60%) had chronic limb-threatening ischemia. A total of 98 (66%) patients underwent endovascular revascularization and 50 (34%) underwent open or hybrid revascularization.
Overall, 3% of subjects were classified as malnourished and 33% were at risk for malnutrition. There were 9 (6%) deaths at 12 months. Mini Nutritional Assessment–Short Form scores were modestly but significantly correlated with the mEFT scores (Pearson’s R = –0.48; P less than .001).
”We found that patients with malnourishment or at risk of malnourishment had a 2.5-fold higher crude 1-year mortality, compared with those with normal nutritional status,” said Dr. Drudi.
In the 41% of patients deemed frail, malnutrition was associated with all-cause mortality (adjusted odds ratio, 2.08 per point decrease in MNA scores); whereas in the nonfrail patients, MNA scores had little or no effect on mortality (adjusted OR, 1.05).
“Preprocedural nutritional status is associated with mortality in frail older adults undergoing interventions for PAD. Clinical trials are needed to determine whether pre- and postprocedural nutritional interventions can improve clinical outcomes in these vulnerable individuals,” Dr. Drudi concluded.

Modest cognitive changes deemed inherent in ‘normal’ aging
Interventions leading to improved gray matter volume tied to reducing dementia risk
CRYSTAL CITY, VA. – As technology advances and the population becomes older, clinicians should understand how modest age-related declines in cognition affect older adults’ ability to learn new technological skills, Philip D. Harvey, PhD, said at Focus on Neuropsychiatry presented by Current Psychiatry and the American Academy of Clinical Psychiatrists.
According to the U.S. Census Bureau, the number of adults in the United States above age 65 is slated to increase over the next several decades, and by 2030, one in five adults in the United States will be at retirement age. By 2050, “a significant number of people” in the United States are expected to be age 90, Dr. Harvey said at the meeting, presented by Global Academy for Medical Education.
“What we need to do is to understand what are the normal things that happen to people as they become 90 years of age,” said Dr. Harvey, of the department of psychiatry and behavioral sciences at the University of Miami.
Within the technology industry, significant advancements were made over the last 40 years with the advent of the personal computer in the 1980s, mobile phones in the 1990s, and wireless Internet, smartphones, and wireless devices in the 2000s. Many interactions that used to be person-to-person are now performed online, and it is feasible for a 90-year-old living today to never have encountered this technology during their careers. “Utilizing technology is a central requirement for independent living today,” Dr. Harvey said.
Most people passively adapt to these new changes in technology. However, Dr. Harvey noted that adults in their 80s and 90s who are retired can have difficulty using or learning about new technology as they age. “Human-technology interaction involves information processing, and places demands on memory and other cognitive abilities,” he said. “Age is associated with declines specifically in the kind of abilities that are required to master new technology.”
Learning about and using technology requires different elements of cognition that include different types of memory, such as working, episodic, declarative, procedural, semantic, long-term factual, and emotional. A decline in any of those kinds of memory could result in failures in forgetting, learning or recalling material, and learning new motor skills, among other problems. Crystallized intelligence is more likely to be retained over time, but fluid cognition in the form of processing speed, working and episodic memory, and the ability to solve abstract problems tend to decline over time as people age, Dr. Harvey said.
Base cognitive abilities do play a role in how crystallized and fluid cognition decline over time. For example, while vocabulary might increase as one ages, a person’s working memory, processing speed, and episodic memory decline over time. Evidence also suggests that speed training and exercise appear to improve cognition. (J Am Geriatr Soc. 13 Jan 2014. doi: 10.1111/jgs.12607).
Cyrus Raji, MD, PhD, and colleagues also explored the relationship between caloric expenditure and gray matter volume in the Cardiovascular Health Study, and found that exercise of various types improved gray matter volume and reduced the risk of dementia in people aged 65 or older. Furthermore, Dr. Raji and colleagues found, caloric expenditures, rather than intensity of exercise, may alone predict increases in gray matter volume (J Alzheimers Dis. 2016. doi: 10.3233/JAD-160057).
“If you want to improve your memory, grow your hippocampus,” Dr. Harvey said at the meeting.
Dr. Harvey reported serving as a consultant for Alkermes, Boehringer-Ingelheim, Lundbeck, Otsuka Digital Health, Sanofi, Sunovion Pharmaceuticals, Takeda, and Teva. He also reported receiving a grant from Takeda, and is the founder and CSO of i-Function.

Evidence also suggests that speed training and exercise appear to improve cognition. (J Am Geriatr Soc. 13 Jan 2014. doi: 10.1111/jgs.12607).
Cyrus Raji, MD, PhD, and colleagues also explored the relationship between caloric expenditure and gray matter volume in the Cardiovascular Health Study, and found that exercise of various types improved gray matter volume and reduced the risk of dementia in people aged 65 or older. Furthermore, Dr. Raji and colleagues found, caloric expenditures, rather than intensity of exercise, may alone predict increases in gray matter volume (J Alzheimers Dis. 2016. doi: 10.3233/JAD-160057).

CRYSTAL CITY, VA. – As technology advances and the population becomes older, clinicians should understand how modest age-related declines in cognition affect older adults’ ability to learn new technological skills, Philip D. Harvey, PhD, said at Focus on Neuropsychiatry presented by Current Psychiatry and the American Academy of Clinical Psychiatrists.
According to the U.S. Census Bureau, the number of adults in the United States above age 65 is slated to increase over the next several decades, and by 2030, one in five adults in the United States will be at retirement age. By 2050, “a significant number of people” in the United States are expected to be age 90, Dr. Harvey said at the meeting, presented by Global Academy for Medical Education.
“What we need to do is to understand what are the normal things that happen to people as they become 90 years of age,” said Dr. Harvey, of the department of psychiatry and behavioral sciences at the University of Miami.
Within the technology industry, significant advancements were made over the last 40 years with the advent of the personal computer in the 1980s, mobile phones in the 1990s, and wireless Internet, smartphones, and wireless devices in the 2000s. Many interactions that used to be person-to-person are now performed online, and it is feasible for a 90-year-old living today to never have encountered this technology during their careers. “Utilizing technology is a central requirement for independent living today,” Dr. Harvey said.
Most people passively adapt to these new changes in technology. However, Dr. Harvey noted that adults in their 80s and 90s who are retired can have difficulty using or learning about new technology as they age. “Human-technology interaction involves information processing, and places demands on memory and other cognitive abilities,” he said. “Age is associated with declines specifically in the kind of abilities that are required to master new technology.”
Learning about and using technology requires different elements of cognition that include different types of memory, such as working, episodic, declarative, procedural, semantic, long-term factual, and emotional. A decline in any of those kinds of memory could result in failures in forgetting, learning or recalling material, and learning new motor skills, among other problems. Crystallized intelligence is more likely to be retained over time, but fluid cognition in the form of processing speed, working and episodic memory, and the ability to solve abstract problems tend to decline over time as people age, Dr. Harvey said.

Cognitive decline sped up after CHD
according to the results of a large prospective study with a median of 12 years of follow-up.
“We found that incident CHD was significantly associated with faster post–CHD-diagnosis cognitive decline, but not pre–CHD-diagnosis or short-term cognitive decline after the event,” Wuxiang Xie, PhD, of Peking University Health Science Center, Beijing, and associates wrote in the Journal of the American College of Cardiology. Linear mixed models showed that cognitive decline sped up during the year after incident CHD.
Past research had suggested a link between accelerated cognitive decline and CHD, but the temporal pattern of the relationship was unclear. For the study, Dr. Xie and associates followed 7,888 adults from the English Longitudinal Study of Aging who were an average of 62 years old and had no history of stroke, MI, angina, or dementia (Alzheimer’s disease or otherwise). All participants underwent a baseline cognitive assessment for verbal memory, semantic fluency, and temporal orientation, plus a median of six follow-up assessments.
In all, 480 (6%) participants developed CHD during follow-up. Their rate of cognitive decline remained constant before and immediately after their CHD diagnosis, but in subsequent years, they experienced significant accelerations in loss of global cognitive function, verbal memory, and temporal orientation even after accounting for time and many demographic and clinical variables. For example, the slope representing temporal change in global cognitive score decreased by a mean of 0.039 per year, compared with the pre-CHD slope (slope difference, –0.039; 95% confidence interval, –0.063 to –0.015; P =. 002). Semantic fluency also declined faster after CHD, but the difference, compared with before CHD, did not reach statistical significance (P = .11).
Individuals without CHD showed no such accelerations in cognitive decline throughout follow-up in adjusted models, the researchers wrote. “Based on repeated cognitive measurements over a long follow-up period, this study revealed a reliable and robust trajectory of cognitive decline [after CHD]. Future studies are warranted to determine the precise mechanisms linking incident CHD to cognitive decline.”

The findings “highlight the role of cardiovascular risk factors and cardiovascular health as crucial determinants of cognitive trajectories in later life,” wrote Suvi P. Rovio, PhD; Katja Pahkala, PhD; and Olli T. Raitakari, MD, PhD. For example, accelerated declines in verbal memory might indicate a specific vulnerability to vascular changes within the medial temporal lobe and hippocampus.
The fact that cognitive decline did not accelerate immediately after coronary heart disease suggests that CHD itself does not acutely alter the brain, such as by causing microinfarcts, they commented. Instead, CHD might induce longer-term shifts in cerebral vascular function by affecting the blood-brain barrier or perfusion and oxidation in the brain. While these complex relationships need further untangling, the study suggests interventions that cut CHD risk also might help prevent cognitive decline itself and slow the rate of cognitive decline if it occurs.

Consider drug treatment in late-life women with osteoporosis
and therefore have more to gain from osteoporosis treatment, regardless of the presence of any comorbidities, according to a new study.
To determine how and when to treat older women for osteoporosis, Kristine E. Ensrud, MD, of the University of Minnesota, Minneapolis, and coauthors studied active surviving participants in the Study of Osteoporotic Fractures. The cohort comprised 1,528 women who met criteria for either osteoporosis (n = 761) or without osteoporosis but at high fracture risk (n = 767). Mean age at the time of examination was 84 years and mean femoral neck bone mineral density (BMD) T-score was −2.24.
During an average follow-up period of 4.4 years after initial examination, 125 women (9%) experienced a hip fracture and 287 (19%) died without experiencing that outcome. The 5-year absolute probability of mortality was 25% (95% confidence interval, 21.8%-28.1%) in women with osteoporosis and 19% (95% CI, 16.6%-22.3%) in women without osteoporosis but at high fracture risk. Although both groups saw mortality probability increase with more comorbidities and poorer prognosis, 5-year hip fracture probability was 13% (95% CI, 10.7%-15.5%) among women with osteoporosis and 4% (95% CI, 2.8%-5.6%) among women without osteoporosis but at high fracture risk.
This probability of the women with osteoporosis experiencing a hip fracture, “even after considering their competing mortality risk” suggests that “initiation of drug treatment in late-life women with osteoporosis may still be effective in the prevention of subsequent hip fracture,” the researchers wrote in JAMA Internal Medicine.
Dr. Ensrud and associates acknowledged their study’s limitations, including the cohort being made up of community-dwelling white women and thus the results not being generalizable to men or women of other racial or ethnic groups. But the researchers noted that the mean femoral neck BMD of women in the study “was essentially identical to that of a nationally representative sample of community-dwelling women 80 years and older enrolled in the 2005 to 2008 NHANES [National Health and Nutrition Examination Survey].”

Older patients with osteoporosis with multimorbidities are the most at risk for hip fractures, which should place an emphasis on research into their treatment, Sarah D. Berry, MD, MPH; Sandra Shi, MD; and Douglas P. Kiel, MD, MPH, of Harvard Medical School, Boston, wrote in an invited commentary.
The coauthors noted that the study by Ensrud et al. is of “great clinical importance, given the ongoing recognition that clinical guidelines should consider multimorbidity.” Currently, the guidelines for treating osteoporosis do not consider age, comorbidities, or frailty, but this study indicates that older women can see benefits from treatment.
They also acknowledged the value of patient preference, referencing a study where 80% of older women “would prefer death as opposed to a hip fracture leading to institutionalization.” All in all, the work of Ensrud et al. is a reminder of “the dangers in ignoring the problem” and the need for future guidelines in osteoporosis treatment to address osteoporosis treatment for older patients with multimorbidity.

LTC-associated suicide among older adults more common than previously thought
The rate of suicide associated with residential long-term care (LTC) in adults aged 55 years and older may be significantly higher than the injury location coding of the National Violent Death Reporting System (NVDRS) suggests, according to new research.
The Centers for Disease Control and Prevention reports that there are about 16,000 nursing homes and 31,000 assisted living facilities in the United States and they currently house about 25% of all Medicare beneficiaries. “As such, residential LTC may be a potential location for identifying individuals at high risk of self-harm and for implementing interventions to reduce suicide risk, wrote Briana Mezuk, PhD, and associates from the University of Michigan, Ann Arbor. The study was published in JAMA Network Open.
Dr. Mezuk and colleagues conducted a cross-sectional, epidemiologic study using a natural language–processing algorithm to analyze restricted-access data from the NVDRS between 2003 and 2015. A total of 47,759 suicides and undetermined deaths in adults aged 55 years and older from 27 states were included in the analysis (median age, 64 years; 77.6% male; 90.0% non-Hispanic white).
The algorithm identified 1,037 (2.2% of the total) suicide deaths associated with LTC, with 428 occurring in adults living in LTC, 449 occurring during the transition into or out of LTC, and 160 otherwise associated with LTC. Decedents in this group had a median age of 79 years, were 73.8% male, and were 94.3% non-Hispanic white. The number of suicide deaths varied widely from year to year, but no trend was found in the change over the study period.
Deaths while living in LTC were more likely among women, which the investigators noted is to be expected because LTC residents are disproportionately women. Death while transitioning into or out of LTC was more likely among adults who previously had expressed suicide ideation and had a physical health problem cited as a contributing circumstance. Death otherwise associated with LTC was more likely in adults who were married or in a relationship, had a depressed mood, and had a recent crisis cited as a contributing factor.
“Living in LTC or transitioning to LTC is also correlated with a host of characteristics that are established risk factors for suicide,” the investigators noted.
In further analysis, the investigators compared the number of suicide deaths the algorithm identified as occurring within an LTC facility (n = 428) with the injury location code SRF (supervised residential facility; n = 263) and the death location code LTC/nursing home (n = 567) within the NVDRS. Of the 263 SRF injuries, 106 were identified as occurring within a LTC facility by the algorithm. The agreement between the algorithm and the SRF coding was poor (kappa statistic, 0.30; 95% confidence interval, 0.26-0.35).
“Leaders in the field have continued to call for a shift away from a medicalized paradigm of residential LTC toward institutional practices that instead focus on fostering meaningful interactions between residents, promote engagement in care, and enhance quality of life. In addition, existing, scalable programs that support older adults living in the community offer the potential to promote quality of life for older adults who may be considering transitioning into or out of residential LTC,” the investigators concluded. “These findings emphasize the importance of such efforts for the mental health of older adults.”
The study was supported by a grant from the National Institute of Mental Health. The investigators reported no conflicts of interest.

Filling the gap in knowledge about the consequences of transitioning into long-term care is sorely needed, wrote Yoram Barak, MD, MHA, and Chris Gale, MB,ChB, MPH, given that fewer than 20 studies on the subject have been published in the past 30 years. A 2015 systematic review of nursing home suicides included only eight studies and 101 suicide deaths.
Despite the limits of an epidemiologic study on long-term care in elderly adults, such as the significant differences between elderly populations in America and other countries, this study by Mezuk et al. provides useful information on a longer period of time than would be possible with case-control studies and at a more granular level than data that would be available from national case registers, Dr. Barak and Dr. Gale wrote.
Dr. Barak and Dr. Gale are with the department of psychological medicine at the University of Otago in Dunedin, New Zealand. They made these comments in an editorial published in JAMA Network Open (2019 Jun 14. doi: 10.1001/jamanetworkopen.2019.5634). They did not report any conflicts of interest.
Filling the gap in knowledge about the consequences of transitioning into long-term care is sorely needed, wrote Yoram Barak, MD, MHA, and Chris Gale, MB,ChB, MPH, given that fewer than 20 studies on the subject have been published in the past 30 years.

The rate of suicide associated with residential long-term care (LTC) in adults aged 55 years and older may be significantly higher than the injury location coding of the National Violent Death Reporting System (NVDRS) suggests, according to new research.
The Centers for Disease Control and Prevention reports that there are about 16,000 nursing homes and 31,000 assisted living facilities in the United States and they currently house about 25% of all Medicare beneficiaries. “As such, residential LTC may be a potential location for identifying individuals at high risk of self-harm and for implementing interventions to reduce suicide risk, wrote Briana Mezuk, PhD, and associates from the University of Michigan, Ann Arbor. The study was published in JAMA Network Open.
Dr. Mezuk and colleagues conducted a cross-sectional, epidemiologic study using a natural language–processing algorithm to analyze restricted-access data from the NVDRS between 2003 and 2015. A total of 47,759 suicides and undetermined deaths in adults aged 55 years and older from 27 states were included in the analysis (median age, 64 years; 77.6% male; 90.0% non-Hispanic white).
The algorithm identified 1,037 (2.2% of the total) suicide deaths associated with LTC, with 428 occurring in adults living in LTC, 449 occurring during the transition into or out of LTC, and 160 otherwise associated with LTC. Decedents in this group had a median age of 79 years, were 73.8% male, and were 94.3% non-Hispanic white. The number of suicide deaths varied widely from year to year, but no trend was found in the change over the study period.
Deaths while living in LTC were more likely among women, which the investigators noted is to be expected because LTC residents are disproportionately women. Death while transitioning into or out of LTC was more likely among adults who previously had expressed suicide ideation and had a physical health problem cited as a contributing circumstance. Death otherwise associated with LTC was more likely in adults who were married or in a relationship, had a depressed mood, and had a recent crisis cited as a contributing factor.
“Living in LTC or transitioning to LTC is also correlated with a host of characteristics that are established risk factors for suicide,” the investigators noted.
In further analysis, the investigators compared the number of suicide deaths the algorithm identified as occurring within an LTC facility (n = 428) with the injury location code SRF (supervised residential facility; n = 263) and the death location code LTC/nursing home (n = 567) within the NVDRS. Of the 263 SRF injuries, 106 were identified as occurring within a LTC facility by the algorithm. The agreement between the algorithm and the SRF coding was poor (kappa statistic, 0.30; 95% confidence interval, 0.26-0.35).
“Leaders in the field have continued to call for a shift away from a medicalized paradigm of residential LTC toward institutional practices that instead focus on fostering meaningful interactions between residents, promote engagement in care, and enhance quality of life. In addition, existing, scalable programs that support older adults living in the community offer the potential to promote quality of life for older adults who may be considering transitioning into or out of residential LTC,” the investigators concluded. “These findings emphasize the importance of such efforts for the mental health of older adults.”
The study was supported by a grant from the National Institute of Mental Health. The investigators reported no conflicts of interest.

Opposing cost trends seen for prescribed medications
according to the Agency for Healthcare Research and Quality.
The average expenditure among persons who used at least one prescription drug went from $1,497 per individual in 2009 to $1,955 in 2016, for an increase of almost 31%. These cost figures cover medications obtained in outpatient settings only and “include the amount paid out of pocket plus any third-party payments from health insurance or other sources,” the AHRQ said.
When out-of-pocket spending for drugs obtained in outpatient settings was considered separately, the average per-person cost dropped by 27%, going from $327 per person with use in 2009 to $238 in 2016, the AHRQ researchers reported.
Over that time period, both total and out-of-pocket costs were considerably and consistently higher for those aged 65 years and older than for those under 65. In 2016, total spending was $3,288 each for elderly persons with at least one prescribed drug purchase and $1,539 for those under age 65, with respective out-of-pocket costs of $401 and $188, they said.
The AHRQ analysis was based on data from the Medical Expenditure Panel Survey, and expenditures for 2009-2015 were adjusted to 2016 dollars.
