A history of head trauma may predict a more rapid decline in patients with Parkinson’s disease, new research suggests.

In a longitudinal online study, among patients with Parkinson’s disease who had a history of head injury, motor impairment developed 25% faster and cognitive impairment developed 45% faster than among those without such a history.

In addition, severe head injuries were associated with an even more rapid onset of impairment. The results give weight to the idea that “it’s head injuries themselves” prior to the development of Parkinson’s disease that might exacerbate motor and cognitive symptoms, said study investigator Ethan Brown, MD, assistant professor, Weill Institute of Neurosciences, department of neurology, University of California, San Francisco.

The findings emphasize the importance of “doing everything we can” to prevent falls and head injuries for patients with Parkinson’s disease, Dr. Brown said.

The findings were presented at the International Congress of Parkinson’s Disease and Movement Disorders.
 

Reverse causality concerns

Head injury is a risk factor for Parkinson’s disease, but its relationship to Parkinson’s disease progression is not well established. “There has always been this concern in Parkinson’s disease that maybe it’s problems with motor impairment that lead to head injuries, so reverse causality is an issue,” said Dr. Brown. “We wanted to look at whether risk factors we know relate to the development of Parkinson’s disease can also have a bearing on its progression,” he added.

The analysis was part of the online Fox Insight study that is evaluating motor and nonmotor symptoms in individuals with and those without Parkinson’s disease. The study included participants who had completed questionnaires on such things as head trauma.

The study included 1,065 patients (47% women; mean age, 63 years) with Parkinson’s disease who reported having had a head injury at least 5 years prior to their diagnosis. Among the participants, the mean duration of Parkinson’s disease was 7.5 years.

The investigators employed a 5-year lag time in their study to exclude head injuries caused by early motor dysfunction, they noted. “We wanted to look at people who had these head injuries we think might be part of the cause of Parkinson’s disease as opposed to a result of them,” Dr. Brown said.

In this head injury group, 51% had received one head injury, 28% had received two injuries, and 22% had received more than two injuries.

The study also included 1,457 participants (56% women; mean age, 65 years) with Parkinson’s disease who had not had a head injury prior to their diagnosis. Of these patients, the mean time with a Parkinson’s disease diagnosis was 8 years.

Dr. Brown noted that the age and sex distribution of the study group was “probably representative” of the general Parkinson’s disease population. However, because the participants had to be able to go online and complete questionnaires, it is unlikely that, among these patients, Parkinson’s disease was far advanced, he said.

The investigators adjusted for age, sex, years of education, and Parkinson’s disease duration.

Two-hit hypothesis?

The researchers compared time from diagnosis to the development of significant motor impairment, such as the need for assistance with walking, and cognitive impairment, such as having a score of less than 43 on the Penn Daily Activities Questionnaire.

They also examined the role of more severe head injuries. In the head injury group, over half (54%) had had a severe head injury, including 543 who had lost consciousness and others who had suffered a fracture or had had a seizure.

Results showed that the adjusted hazard ratio for developing motor impairment among those with a head injury, compared with those who had not had a head injury was 1.24 (95% confidence interval, 1.01-1.53; P = .037). For severe injuries, the aHR for motor impairment was 1.44 (95% CI, 1.13-1.83; P = .003).

For cognitive impairment, the aHR for those with versus without head injuries was 1.45 (95% CI, 1.14-1.86; P = .003); and for severe injuries, the aHR was 1.49 (95% CI, 1.11-2.0; P = .008).

Aside from severity, the researchers did not examine subgroups. However, Dr. Brown reported that his team would like to stratify results by sex and other variables in the future.

He noted that various mechanisms may explain why Parkinson’s disease progression is faster for patients who have a history of head injury, compared with others. Chronic inflammation due to the injury and “co-pathology” might play some role, he said. He noted that head injuries are associated with cognitive impairment in other conditions, including Alzheimer’s disease.

There is also the “two hit” hypothesis, Dr. Brown said. “A head injury could cause such broad damage that once people develop Parkinson’s disease, it’s harder for them to compensate.”

Dr. Brown also noted there might have been a “higher magnitude” of a difference between groups had the study captured participants with more severe symptoms.
 

‘Provocative’ findings

Michael S. Okun, MD, medical advisor at the Parkinson’s Foundation and professor and director at the Norman Fixel Institute for Neurological Diseases, University of Florida, Gainesville, said the new data are “provocative.”

“The idea that a head injury may be important in predicting how quickly and how severely deficits will manifest could be important to the treating clinician,” said Dr. Okun, who was not involved with the research.

He noted that the results suggest clinicians should elicit more information from patients about head trauma. “They should be seeking more than a binary ‘yes or no’ answer to head injury when questioning patients,” he added.

Dr. Okun reiterated that head injury is a “known and important risk factor” not only for Parkinson’s disease but also for other neurodegenerative diseases. “It’s important to counsel patients about the association,” he said.

The study was supported by the Michael J. Fox Foundation. Dr. Brown reports having received grant support from the Michael J. Fox Foundation. Dr. Okun has reported no relevant financial relationships.

Following an online yoga program improves physical function in patients with knee osteoarthritis, according to the results of a new randomized control trial.

Although pain did not significantly improve in the yoga group, participants only completed about two-thirds of the recommended sessions, suggesting that more benefit may be possible with greater adherence, wrote lead author Kim L. Bennell, PhD, of the University of Melbourne, and colleagues in the Annals of Internal Medicine.

“To date, an online yoga program specifically for people with knee osteoarthritis has not been investigated,” the investigators said. “The need for such evidence-based packaged online exercise programs is highlighted in the 2020 U.S. National Public Health Agenda for Osteoarthritis.”
 

Methods and results

The trial involved 212 adults aged 45 years or older with symptomatic knee osteoarthritis. All patients had access to online educational materials about managing osteoarthritis.

Half of the participants were randomized into the 12-week online yoga program. This self-directed, unsupervised course consisted of 12 prerecorded 30-minute instructional yoga sessions, each with a unique sequence of poses to be completed three times in one week before moving on to the next class the following week. After 12 weeks, these participants could choose to continue doing yoga via the online program for 12 additional weeks, if desired.

The primary outcomes were knee pain and physical function, gauged by a 10-point numerical rating scale and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), respectively. Adherence was defined as completion of at least 2 yoga sessions within the preceding week.

At the 12-week mark, the yoga group did not show any significant improvement in knee pain (–0.6; 95% confidence interval, –1.2 to 0.1), but they did achieve a mean 4-point reduction in WOMAC, suggesting significant improvement in knee function (­–4.0; 95% CI, –6.8 to –1.3). Of note, however, this improvement was not enough to meet the threshold for minimal clinically important difference. At 24 weeks, the yoga group no longer showed significant improvement in knee function versus baseline.

“I don’t think a longer program would necessarily reduce knee pain, as benefits from a whole range of different types of exercise for knee osteoarthritis generally can show benefits within 8 weeks,” Dr. Bennell said in an interview.

Still, she noted that the average outcome in the trial may not represent what is possible if a patient commits to a regular yoga routine.

“I think it relates more to adherence [than duration], and I think benefits for knee pain would have been seen if a greater number of people had fully adhered to the program three times a week,” she said.

At 12 weeks, 68.8% of those in the yoga group were adherent, while just 28.4% were still adherent at week 24 after the optional extension period.

“As this was a self-directed program, adherence might be expected to be less than that of a supervised program,” Dr. Bennell noted.

Referring to unpublished data, Dr. Bennell said a sensitivity analysis showed that participants in the yoga group who completed yoga at least twice a week did show greater improvements in function and pain than those who did yoga less than twice per week.

“So it does suggest that adherence is important, as we might expect,” she said.
 

Another tool in the OA toolbox

Nick Trasolini, MD, of Wake Forest University School of Medicine, Winston-Salem, N.C., described the benefits in the trial as “modest” and noted that the improvement in function did not meet the threshold for minimal clinically important difference.

“Nevertheless,” he said in a written comment, “the [yoga] program was safe and associated with high participant satisfaction [mean satisfaction, 8 out of 10]. While this may not be the ‘silver bullet,’ it is another tool that we can offer to sufficiently motivated patients seeking non-operative solutions for knee osteoarthritis.”

Unfortunately, these tools remain “fraught with challenges,” Dr. Trasolini added.

“While multiple injection options are available (including corticosteroid, hyaluronic acid viscosupplementation, and biologic injections), the benefits of these injections can be short-lived,” he said. “This is frustrating to patients and physicians alike. Physical therapy is beneficial for knee osteoarthritis when deconditioning has led to decreased knee, hip, and core stability. However, physical therapy can be time consuming, painful, and cost prohibitive.”

In the present study, participants in the yoga group were somewhat willing (mean willingness, 5 out of 10) to pay for their 12-week yoga program. They reported that they would pay approximately $80 U.S. dollars for chance to do it all again.

The study was supported by grants from the National Health and Medical Research Council Program and the Centres of Research Excellence. The investigators disclosed additional relationships with Pfizer, Lilly, TLCBio, and others. Dr. Trasolini disclosed no relevant conflicts of interest.

New research calls into question the assumption that acetaminophen is safer than NSAIDs for patients with known cardiovascular disease (CVD) or CVD risk factors.

The analysis found a significant correlation between the use of acetaminophen and elevated systolic blood pressure.

While acetaminophen may still be safer than NSAIDs from a bleeding risk standpoint, or in patients with known kidney disease, “the gap may not be as large as once thought,” Rahul Gupta, MD, cardiologist with Lehigh Valley Health Network, Allentown, Pa., said in an interview.

Subgroup analysis of the effect on hypertensive patients showed significant change in systolic blood pressure as well (SMD = 0.38; 95% CI, 0.05-0.71; P = .02).

“Interestingly, there was no significant difference in the effect on diastolic blood pressure,” Dr. Gupta commented.

Reached for comment, Timothy S. Anderson, MD, clinical investigator in the Division of General Medicine at Beth Israel Deaconess Medical Center and assistant professor of medicine at the Harvard Medical School, both in Boston, said this is “an interesting and not particularly well-known issue.”

“However, most of the trials look at very high doses of acetaminophen use (for example, six to eight of the 500 mg pills each day) so we don’t really know whether the more common patterns of using one to two acetaminophen pills every once in a while is problematic,” Dr. Anderson told this news organization.

“We also don’t have data showing a direct harm from these medications with regards to strokes or heart attacks or other downstream consequences of high blood pressure. Ideally we would need a head-to-head trial comparing ibuprofen-type medications to acetaminophen-type medications,” Dr. Anderson said.

The study had no specific funding. Dr. Gupta and Dr. Anderson reported no relevant disclosures.

Subgroup analysis of the effect on hypertensive patients showed significant change in systolic blood pressure as well (SMD = 0.38; 95% CI, 0.05-0.71; P = .02).

“Interestingly, there was no significant difference in the effect on diastolic blood pressure,” Dr. Gupta commented.

Reached for comment, Timothy S. Anderson, MD, clinical investigator in the Division of General Medicine at Beth Israel Deaconess Medical Center and assistant professor of medicine at the Harvard Medical School, both in Boston, said this is “an interesting and not particularly well-known issue.”

“However, most of the trials look at very high doses of acetaminophen use (for example, six to eight of the 500 mg pills each day) so we don’t really know whether the more common patterns of using one to two acetaminophen pills every once in a while is problematic,” Dr. Anderson told this news organization.

“We also don’t have data showing a direct harm from these medications with regards to strokes or heart attacks or other downstream consequences of high blood pressure. Ideally we would need a head-to-head trial comparing ibuprofen-type medications to acetaminophen-type medications,” Dr. Anderson said.

The study had no specific funding. Dr. Gupta and Dr. Anderson reported no relevant disclosures.

New research calls into question the assumption that acetaminophen is safer than NSAIDs for patients with known cardiovascular disease (CVD) or CVD risk factors.

The analysis found a significant correlation between the use of acetaminophen and elevated systolic blood pressure.

While acetaminophen may still be safer than NSAIDs from a bleeding risk standpoint, or in patients with known kidney disease, “the gap may not be as large as once thought,” Rahul Gupta, MD, cardiologist with Lehigh Valley Health Network, Allentown, Pa., said in an interview.

Treatment of people with obesity but without diabetes with the glucagon-like peptide-1 (GLP-1) agonist semaglutide (Wegovy) – hailed at its approval in 2021 as a “game changer” for the treatment of obesity – led to beneficial changes in body mass index (BMI), glycemic control, and other clinical measures.

This collectively cut the calculated risk for possible future development of type 2 diabetes in study participants by more than half, based on post-hoc analysis of data from two pivotal trials that compared semaglutide with placebo.

The findings “suggest that semaglutide could help prevent type 2 diabetes in people with overweight or obesity,” said W. Timothy Garvey, MD, in a presentation at the annual meeting of the European Association for the Study of Diabetes.

Asked to comment, Rodolfo J. Galindo, MD, said: “We devote a significant amount of effort to treating people with diabetes but very little effort for diabetes prevention. We hope that further scientific findings showing the benefits of weight loss, as illustrated by [Dr.] Garvey [and colleagues], for diabetes prevention will change the pandemic of adiposity-based chronic disease.”
 

GLP-1 agonists as complication-reducing agents

Finding a link between treatment with semaglutide and a reduced future risk of developing type 2 diabetes is important because it shows that this regimen is not just a BMI-centric approach to treating people with obesity but is also a way to potentially reduce complications of obesity such as diabetes onset, explained Dr. Garvey, a professor and director of the Diabetes Research Center at the University of Alabama at Birmingham.

Recent obesity-management recommendations have focused on interventions aimed at avoiding complications, as in 2016 guidelines from the American Association of Clinical Endocrinologists and the American College of Endocrinology, he noted.

Having evidence that treatment with a GLP-1 agonist such as semaglutide can reduce the incidence of diabetes in people with obesity might also help convince payers to more uniformly reimburse for this type of obesity intervention, which up to now has commonly faced coverage limitations, especially in the United States, he said in an interview.

Dr. Garvey added that evidence for a reduction in the incidence of cardiovascular disease complications such as myocardial infarction and stroke may need to join diabetes prevention as proven effects from obesity intervention before coverage decisions change.

He cited the SELECT trial, which is testing the hypothesis that semaglutide treatment of people with overweight or obesity can reduce the incidence of cardiovascular events in about 17,500 participants and with expected completion toward the end of 2023.

“A complication-centric approach to management of people with obesity needs prediction tools that allow a focus on prevention strategies for people with obesity who are at increased risk of developing diabetes,” commented Dr. Galindo, an endocrinologist at Emory University, Atlanta, in an interview.
 

Combined analysis of STEP 1 and STEP 4 data

The analysis conducted by Dr. Garvey and colleagues used data from the STEP 1 trial, which compared semaglutide 2.4 mg subcutaneous once weekly with placebo for weight loss in more than 1,500 people predominantly with obesity (about 6% were overweight) and showed that after 68 weeks semaglutide cut the calculated risk of developing type 2 diabetes over the subsequent 10 years from 18% at baseline to 7%, compared with a drop from 18% at baseline to 16% among those who received placebo.

A second, similar analysis of data from people predominantly with obesity in the STEP 4 trial – which treated around 800 people with semaglutide 2.4 mg for 20 weeks and then randomized them to placebo or continued semaglutide treatment – showed that semaglutide treatment cut their calculated 10-year risk for incident type 2 diabetes from 20% at baseline to about 11% after 20 weeks. The risk rebounded in the study participants who then switched from semaglutide to placebo. Among those randomized to remain on semaglutide for a total of 68 weeks, the 10-year risk fell further to 8%.

Dr. Garvey and associates used a validated prognostic formula, the cardiometabolic disease staging (CMDS) tool, they had previously developed and reported to calculate 10-year risk for development of type 2 diabetes based on three unmodifiable factors (age, sex, and race) and five modifiable factors (BMI, blood pressure, glucose level, HDL cholesterol, and triglycerides). They applied the analysis to data from 1,561 of the STEP 1 participants and 766 participants in the STEP 4 study.

“There is no better tool I know of to predict diabetes incidence,” commented Michael A. Nauck, MD, professor and chief of clinical research, diabetes division, St. Josef Hospital, Bochum, Germany.

In his opinion, the CMDS tool is appropriate for estimating the risk of developing incident type 2 diabetes in populations but not in specific individuals.

The new analyses also showed that, in STEP 1, the impact of semaglutide on reducing future risk of developing type 2 diabetes was roughly the same regardless of whether participants entered the study with prediabetes or were normoglycemic at entry.

Blood glucose changes confer the biggest effect

The biggest contributor among the five modifiable components of the CMDS tool for altering the predicted risk for incident diabetes was the reduction in blood glucose produced by semaglutide treatment, which influenced just under half of the change in predicted risk, Dr. Garvey said. The four other modifiable components had roughly similar individual effects on predicted risk, with change in BMI influencing about 15% of the observed effect.

“Our analysis shows that semaglutide treatment is preventing diabetes via several mechanisms. It’s not just a reduction in glucose,” Dr. Garvey said.

Dr. Nauck cautioned, however, that it is hard to judge the efficacy of an intervention like semaglutide for preventing incident diabetes when one of its effects is to dampen down hyperglycemia, the signal indicator of diabetes onset.

Indeed, semaglutide was first approved as a treatment for type 2 diabetes (known as Ozempic, Novo Nordisk) at slightly lower doses than it is approved for obesity. It is also available as an oral agent to treat diabetes (Rybelsus).  

Dr. Nauck also noted that the results from at least one previously reported study had already shown the same relationship between treatment with the GLP-1 agonist liraglutide as an anti-obesity agent (3.0 mg dose daily, known as Saxenda) and a reduced subsequent incidence of type 2 diabetes but using actual clinical outcomes during 3 years of follow-up rather than a calculated projection of diabetes likelihood.

The SCALE Obesity and Prediabetes trial randomized 2,254 people with prediabetes and overweight or obesity to weekly treatment with 3.0 mg of liraglutide or placebo. After 160 weeks on treatment, the cumulative incidence of type 2 diabetes was 2% in those who received liraglutide and 6% among those on placebo, with a significant hazard ratio reduction of 79% in the incidence of diabetes on liraglutide treatment.

The STEP 1 and STEP 4 trials were sponsored by Novo Nordisk, the company that markets semaglutide (Wegovy). Dr. Garvey has reported serving as an advisor without compensation to Novo Nordisk as well as Boehringer Ingelheim, Eli Lilly, Jazz, and Pfizer. He is also a site principal investigator for multicentered clinical trials sponsored by the University of Alabama at Birmingham and funded by Novo Nordisk, Eli Lilly, Epitomee, and Pfizer. Dr .Galindo has reported being a consultant or advisor for Boehringer Ingelheim, Eli Lilly, Pfizer, Sanofi, and Weight Watchers and receiving research funding from Dexcom, Eli Lilly, and Novo Nordisk. Dr. Nauck has reported being an advisor or consultant to Novo Nordisk as well as to Boehringer Ingelheim, Eli Lilly, Menarini/Berlin Chemie, MSD, Regor, and ShouTi/Gasherbrum, receiving research funding from MSD, being a member of a data monitoring and safety board for Inventiva, and being a speaker on behalf of Novo Nordisk as well as for Eli Lilly, Menarini/Berlin Chemie, MSD, and Sun Pharmaceuticals.

Just over 51% of older hypertensive adults regularly check their own blood pressure, compared with 48% of those with blood pressure–related health conditions (BPHCs), based on a 2021 survey of individuals aged 50-80 years.

“Guidelines recommend that patients use self-measured blood pressure monitoring (SBPM) outside the clinic to diagnose and manage hypertension,” but just 61% of respondents with a BPHC and 68% of those with hypertension said that they had received such a recommendation from a physician, nurse, or other health care professional, Melanie V. Springer, MD, and associates said in JAMA Network Open.

The prevalence of regular monitoring among those with hypertension, 51.2%, does, however, compare favorably with an earlier study showing that 43% of adults aged 18 and older regularly monitored their BP in 2005 and 2008, “which is perhaps associated with our sample’s older age,” said Dr. Springer and associates of the University of Michigan, Ann Arbor.

The current study, they noted, is the first to report “SBPM prevalence in adults ages 50 to 80 years with hypertension or BPHCs, who have a higher risk of adverse outcomes from uncontrolled BP than younger adults.” The analysis is based on data from the National Poll on Healthy Aging, conducted by the University of Michigan in January 2021 and completed by 2,023 individuals.

The frequency of home monitoring varied among adults with BPHCs, as just under 15% reported daily checks and the largest proportion, about 28%, used their device one to three times per month. The results of home monitoring were shared with health care professionals by 50.2% of respondents with a BPHC and by 51.5% of those with hypertension, they said in the research letter.

Home monitoring’s less-than-universal recommendation by providers and use by patients “suggest that protocols should be developed to educate patients about the importance of SBPM and sharing readings with clinicians and the frequency that SBPM should be performed,” Dr. Springer and associates wrote.

The study was funded by AARP, Michigan Medicine, the National Institute of Neurological Disorders and Stroke, and the Department of Veterans Affairs. One investigator has received consulting fees or honoraria from SeeChange Health, HealthMine, the Kaiser Permanente Washington Health Research Institute, the Robert Wood Johnson Foundation, AbilTo, Kansas City Area Life Sciences Institute, American Diabetes Association, Donaghue Foundation, and Luxembourg National Research Fund.

Wearing a cuffless device on the wrist to continuously monitor blood pressure was associated with a significantly lower systolic BP at 6 months among hypertensive adults, real-world results from Europe show.

“We don’t know what they did to reduce their blood pressure,” Jay Shah, MD, Division of Cardiology, Mayo Clinic Arizona, Phoenix, told this news organization.

“The idea is that because they were exposed to their data on a continual basis, that may have prompted them to do something that led to an improvement in their blood pressure, whether it be exercise more, go to their doctor, or change their medication,” said Dr. Shah, who is also chief medical officer for Aktiia.

Dr. Shah presented the study at the Hypertension Scientific Sessions, San Diego.
 

Empowering data

The study used the Aktiia 24/7 BP monitor; Atkiia funded the trial. The monitor passively and continually monitors BP values from photoplethysmography signals collected via optical sensors at the wrist.

After initial individualized calibration using a cuff-based reference, BP measurements are displayed on a smartphone app, allowing users to consistently monitor their own BP for long periods of time.

Aktiia received CE mark in Europe in January 2021 and is currently under review by the U.S. Food and Drug Administration.

Dr. Shah and colleagues analyzed systolic BP (SBP) trends among 838 real-world Aktiia users in Europe (age 57 ± 11 years; 14% women) who consistently used the monitor for 6 months.

Altogether, they had data on 375 (± 287) app interactions, 3,646 (± 1,417) cuffless readings per user, and 9 (± 7) cuff readings per user.

Traditional cuff SBP averages were calculated monthly and compared with the SBP average of the first month. A t-test analysis was used to detect the difference in SBP between the first and successive months.

On the basis of the mean SBP calculated over 6 months, 136 participants were hypertensive (SBP > 140 mm Hg) and the rest had SBP less than 140 mm Hg.

Hypertensive users saw a statistically significant reduction in SBP of –3.2 mm Hg (95% CI, –0.70 to –5.59; P < .02), beginning at 3 months of continual cuffless BP monitoring, which was sustained through 6 months.

Among users with SBP less than 140 mm Hg, the mean SBP remained unchanged.

“The magnitude of improvement might look modest, but even a 5 mm Hg reduction in systolic BP correlates to a 10% decrease in cardiovascular risk,” Dr. Shah told this news organization.

He noted that “one of the major hurdles is that people may not be aware they have high blood pressure because they don’t feel it. And with a regular cuff, they’ll only see that number when they actually check their blood pressure, which is extremely rare, even for people who have hypertension.”

“Having the ability to show someone their continual blood pressure picture really empowers them to do something to make changes and to be aware, [as well as] to be a more active participant in their health,” Dr. Shah said.

He said that a good analogy is diabetes management, which has transitioned from single finger-stick glucose monitoring to continuous glucose monitoring that provides a complete 24/7 picture of glucose levels.

“This could unlock an era of precision BP management with empowerment of patients to view and act on their numbers,” Dr. Krumholz said in an interview.

“We need data to be confident in the devices – and then research to best leverage the streams of information – and strategies to optimize its use in practice,” Dr. Krumholz added.

“Like any new innovation, we need to mitigate risks and monitor for unintended adverse consequences, but I am bullish on the future of cuffless continuous BP monitors,” Dr. Krumholz said.

Dr. Krumholz said that he “applauds Aktiia for doing studies that assess the effect of the information they are producing on BP over time. We need to know that new approaches not only generate valid information but that they can improve health.”
 

Ready for prime time?

In June, the European Society of Hypertension issued a statement noting that cuffless BP measurement is a fast-growing and promising field with considerable potential for improving hypertension awareness, management, and control, but because the accuracy of these new devices has not yet been validated, they are not yet suitable for clinical use.

Also providing perspective, Stephen Juraschek, MD, PhD, research director, Hypertension Center of Excellence at Healthcare Associates, Beth Israel Deaconess Medical Center, Boston, said that “there is a lot of interest in cuffless BP monitors due to their ease of measurement, comfort, and ability to obtain BP measurements in multiple settings and environments, and this study showed that the monitoring improved BP over time.”

“It is believed that the increased awareness and feedback may promote healthier behaviors aimed at lowering BP. However, this result should not be conflated with the accuracy of these monitors,” Dr. Juraschek cautioned.

He also noted that there is still no formally approved validation protocol by the Association for the Advancement of Medical Instrumentation.

“While a number of cuffless devices are cleared by the FDA through its 510k mechanism (that is, demonstration of device equivalence), there is no formal stamp of approval or attestation that the measurements are accurate,” Dr. Juraschek said in an interview.

In his view, “more work is needed to understand the validity of these devices. For now, validated, cuff-based home devices are recommended for BP measurement at home, while further work is done to determine the accuracy of these cuffless technologies.”

The study was funded by Aktiia. Dr. Shah is an employee of the company. Dr. Krumholz has no relevant disclosures. Dr. Juraschek is a member of the Validate BP review committee and the AAMI sphygmomanometer committee.

Among patients with severe isolated aortic stenosis younger than 65, the rate of transcatheter aortic valve replacement (TAVR) now almost matches that of surgical aortic valve replacement (SAVR), despite guideline recommendations to the contrary, a study in a national U.S. population shows.

The 2020 American Heart Association/American College of Cardiology (AHA/ACC) valve guideline recommends SAVR for patients younger than 65 with severe aortic stenosis, the researchers note, but their study showed “near equal utilization between TAVR and SAVR in these younger patients by 2021,” at 48% and 52% respectively.

Toishi Sharma, MD, and colleagues presented these findings in an oral poster session at Transcatheter Cardiovascular Therapeutics 2022, and the study was simultaneously published as a Research Letter in the Journal of the American College of Cardiology (JACC).

“To our knowledge, the current findings represent the first national temporal trends study stratifying [aortic stenosis] therapies according to guideline-recommended age groups: our observations demonstrate the dramatic growth of TAVR in all age groups, including young patients,” the researchers conclude.

They analyzed changes in rates of TAVR and SAVR in a U.S. sample stratified by age: younger than 65 years, 65-80, and older than 80 years.

These findings have implications for lifetime management of younger patients who undergo TAVR, they write, “including issues related to lifetime coronary access, valve durability, and the potential for subsequent TAVR procedures over time.”
 

Three age groups

In a study published in JACC, this group examined changes in uptake of TAVR versus SAVR in 4,161 patients with aortic stenosis in Vermont, New Hampshire, and Maine, senior author Harold L. Dauerman, MD, said in an interview.

The greatest rate of rise of TAVR was in the group younger than 65, but that study ended in 2019, said Dr. Dauerman, from the University of Vermont Health Network, Burlington.

The 2020 guideline stratifies TAVR and SAVR recommendations such that “less than 65 should primarily be a surgical approach and greater than 80 primarily a TAVR approach, while 65 to 80 is a gray zone, and shared decision-making becomes important,” he noted.

The group hypothesized that recent trials and technology have led to a national increase in TAVR in people younger than 65.

From the Vizient clinical database, including more than 250 U.S. academic centers that perform both TAVR and SAVR, the researchers identified 142,953 patients who underwent TAVR or SAVR for isolated aortic stenosis from Oct. 1, 2015, to Dec. 31, 2021. From 2015 to 2021, the valve replacement rates in the three age groups changed as follows:

• Age less than 65: TAVR rose from 17% to 48%; SAVR fell from 83% to 52%.
• Age 65-80: TAVR rose from 46% to 87%; SAVR fell from 54% to 12%.
• Age greater than 80: TAVR rose from 83% to 99%; SAVR fell from 16% to 1%.

“All ages have grown in the last 7 years in TAVR,” Dr. Dauerman summarized. “The one that’s surprising, and in contradiction to the guideline, is the growth of TAVR in young patients less than 65.”

Among patients younger than 65, prior bypass surgery and congestive heart failure predicted the use of TAVR instead of surgery, whereas bicuspid aortic valve disease was the biggest predictor of surgery instead of TAVR.

Most studies on TAVR valve durability are limited to patients in the randomized trials who were primarily in their mid-70s to mid-80s, some of whom died before a 10-year follow-up, Dr. Dauerman noted.

European guidelines recommend surgery for patients younger than 70, and it would be interesting to see if clinicians there follow this recommendation or if TAVR is now the preferred approach, he added.

There is a need for further, longer study of TAVR in younger patients, he said, to determine whether there are long-term clinical issues of concern.
 

Strategy depends on more than age

The “findings are not too surprising,” John Carroll, MD, who was not involved in this research, said in an email.

University of Colorado Hospital

“Age is only one of multiple patient characteristics that enter into consideration of TAVR versus SAVR,” said Dr. Carroll, from Anschutz Medical Campus, University of Colorado, Aurora.

“As the article reports,” he noted, “those less than 65 having TAVR are more likely to have comorbid conditions that likely made the risk of SAVR higher.”

Dr. Carroll was lead author of a review article published in 2020 based on data from the ACC–Society of Thoracic Surgeons (STS)–Transcatheter Valve Therapy (TVT) registry on 276,316 patients who had TAVR in the United States from 2011-2019.

He pointed out that Figure 2 in that review shows that “SAVR is often performed in conjunction with other surgical procedures – another major reason why SAVR remains an important treatment for valvular heart disease.”

“We are awaiting long-term data comparing TAVR to SAVR durability,” Dr. Carroll added, echoing Dr. Dauerman. “So far [there are] no major differences, but it remains a key need to fully understand TAVR and the various models in commercial use.”

“Both TAVR and SAVR used in adults are tissue valves (SAVR with mechanical valves is used in younger patients),” Dr. Carroll noted, “and all tissue valves will eventually fail if the patient lives long enough.”

Patient management strategies need to consider what treatment options exist when the first valve fails. “If the first valve is SAVR, there is now extensive experience with placing a TAVR valve inside a failing SAVR valve, so called Valve-in-Valve or TAVR-in-SAVR. This is the preferred treatment in most patients with failing SAVR valves,” he said.

“On the other hand,” he continued, “we are just beginning to see more and more patients with failing TAVR valves, and the TAVR-in-TAVR procedure is less well understood.”

“Issues such as acute coronary occlusion and long-term difficulty in accessing coronary arteries are being encountered in some patients having TAVR-in-TAVR,” Dr. Carroll noted, which he discusses in a recent editorial he coauthored about the complexities of redo TAVR, published in JACC: Cardiovascular Interventions.

The study received no funding. Dr. Dauerman has research grants and is a consultant for Medtronic and Boston Scientific. Dr. Carroll is a local principal investigator in trials sponsored by Medtronic, Abbott, and Edwards Lifesciences.

Most studies on TAVR valve durability are limited to patients in the randomized trials who were primarily in their mid-70s to mid-80s, some of whom died before a 10-year follow-up, Dr. Dauerman noted.

European guidelines recommend surgery for patients younger than 70, and it would be interesting to see if clinicians there follow this recommendation or if TAVR is now the preferred approach, he added.

There is a need for further, longer study of TAVR in younger patients, he said, to determine whether there are long-term clinical issues of concern.
 

Strategy depends on more than age

The “findings are not too surprising,” John Carroll, MD, who was not involved in this research, said in an email.

“Age is only one of multiple patient characteristics that enter into consideration of TAVR versus SAVR,” said Dr. Carroll, from Anschutz Medical Campus, University of Colorado, Aurora.

“As the article reports,” he noted, “those less than 65 having TAVR are more likely to have comorbid conditions that likely made the risk of SAVR higher.”

Dr. Carroll was lead author of a review article published in 2020 based on data from the ACC–Society of Thoracic Surgeons (STS)–Transcatheter Valve Therapy (TVT) registry on 276,316 patients who had TAVR in the United States from 2011-2019.

He pointed out that Figure 2 in that review shows that “SAVR is often performed in conjunction with other surgical procedures – another major reason why SAVR remains an important treatment for valvular heart disease.”

“We are awaiting long-term data comparing TAVR to SAVR durability,” Dr. Carroll added, echoing Dr. Dauerman. “So far [there are] no major differences, but it remains a key need to fully understand TAVR and the various models in commercial use.”

“Both TAVR and SAVR used in adults are tissue valves (SAVR with mechanical valves is used in younger patients),” Dr. Carroll noted, “and all tissue valves will eventually fail if the patient lives long enough.”

Patient management strategies need to consider what treatment options exist when the first valve fails. “If the first valve is SAVR, there is now extensive experience with placing a TAVR valve inside a failing SAVR valve, so called Valve-in-Valve or TAVR-in-SAVR. This is the preferred treatment in most patients with failing SAVR valves,” he said.

“On the other hand,” he continued, “we are just beginning to see more and more patients with failing TAVR valves, and the TAVR-in-TAVR procedure is less well understood.”

“Issues such as acute coronary occlusion and long-term difficulty in accessing coronary arteries are being encountered in some patients having TAVR-in-TAVR,” Dr. Carroll noted, which he discusses in a recent editorial he coauthored about the complexities of redo TAVR, published in JACC: Cardiovascular Interventions.

The study received no funding. Dr. Dauerman has research grants and is a consultant for Medtronic and Boston Scientific. Dr. Carroll is a local principal investigator in trials sponsored by Medtronic, Abbott, and Edwards Lifesciences.

Researchers have developed a blood test that can detect hepatocellular carcinoma (HCC) at an early stage, increasing the likelihood of potentially curative therapy and improved patient prognosis.

HCC accounts for the majority of primary liver cancers and mainly occurs in patients with cirrhosis or chronic hepatitis B virus infection. The prognosis of HCC is poor, largely owing to advanced disease stage at diagnosis.

The current guidelines recommend surveillance with twice-yearly liver ultrasound, with or without serum alpha-fetoprotein, for patients at risk for HCC, although the diagnostic performance is suboptimal.

The new “liquid biopsy” uses HCC-associated extracellular vesicles (EVs) to establish an HCC EV ECG score for distinguishing patients with early-stage HCC from at-risk controls with cirrhosis from a 400-mcL plasma sample.

“We’re the first team looking at extracellular vesicles as a detection biomarker for early-stage liver cancer, and our study showed it had outstanding performance,” study investigator Ju Dong Yang, MD, with Cedars-Sinai Medical Center, Los Angeles, said in a news release.

The study was published online in Hepatology.

In a phase 2 biomarker (case-control) study, the investigators tested their blood test in a training cohort of 106 individuals (45 patients with treatment-naive early-stage HCC and 61 with cirrhosis) and an independent validation cohort with 72 participants (35 patients with treatment-naive early-stage HCC and 37 with cirrhosis).

The HCC EV ECG score had “excellent accuracy” for discriminating between HCC and cirrhosis, with an area under the receiver operating characteristic curve (AUROC) of 0.95 and 0.93 in the training and validation cohorts, respectively, they report.

The diagnostic performance “remained excellent” among the subpopulations of HCC etiology and those with tumors within the Milan criteria.

Adding the serum alpha-fetoprotein level to the HCC EV ECG score did not improve its performance.

The researchers say that further validation of the blood test in a larger phase 2 study and a subsequent phase 3 study are needed to confirm its utility in clinical settings.

“We are planning on doing larger-scale studies to further validate this test and bring it into routine clinical practice here – and globally,” Dr. Yang said.

“In addition to its excellent performance, this marker has the advantages of being user friendly, cost efficient, and having a fast turnaround time – within 6 hours from sample collection to result,” Dan Theodorescu, MD, PhD, director of Cedars-Sinai Cancer, who is not an author on the study, said in the news release.

“Once this marker has been validated in subsequent studies, it can be easily adopted by existing PCR [polymerase chain reaction] facilities,” Dr. Theodorescu added.

The study was supported by an American College of Gastroenterology Junior Faculty Development Award, a Department of Defense Peer Reviewed Cancer Research Program Career Development Award, and the National Institutes of Health. Dr. Yang provides a consulting service for Exact Sciences, Gilead Sciences, and Eisai. Dr. Theodorescu reports no relevant financial relationships.

Adderall, the attention-deficit/hyperactivity disorder medication, is in short supply in some parts of the nation, pharmacy chains and Adderall users say.

Half a dozen people told Bloomberg that pharmacies told them in August and September that the drug was out of stock. The patients were told the drug might not be available for weeks, though it’s supposed to be taken daily. BuzzFeed News said 20 people across the nation said that their pharmacies didn’t have Adderall in stock.

“It’s so frustrating that getting my meds requires me to be organized, focused, and motivated – all the things I’m on these meds to help with,” Irene Kelly, who has been using Adderall for 14 years, told BuzzFeed News.

Two pharmacy chains told Bloomberg that Adderall has not always been available to sell. Walgreens spokesperson Rebekah Pajak said there were “supply chain challenges” affecting instant-release and extended-release versions of the drug. CVS pharmacies can fill Adderall prescriptions “in most cases,” CVS spokesperson Matthew Blanchette said.

Several drugmakers have had brand-name and generic versions of Adderall on back order for months, Bloomberg reported. The problem started with a labor shortage at Teva Pharmaceutical, the top seller of Adderall in the United States, that created a limited supply of brand-name and generic instant-release Adderall, according to the outlet.

That said, the Food and Drug Administration is not reporting an Adderall shortage on its drug shortages database. The federal agency says it lists a drug as being in short supply when “overall market demand is not being met by the manufacturers of the product,” Bloomberg said.

“Manufacturers continue to release product,” FDA spokesperson Cherie Duvall-Jones said, according to Bloomberg.

Demand for Adderall is growing, possibly because of rising ADHD diagnoses that occurred during telehealth medical appointments amid the COVID-19 pandemic, Bloomberg reported, noting that some of those telehealth companies have come under scrutiny by the Drug Enforcement Administration and other government agencies.

NBC News, citing IQVIA, an analytics provider for the life sciences industry, reported that 41.4 million Adderall prescriptions were issued last year, up 10.4% from 2020.
