Psychological therapy that changes an individual’s beliefs about pain not only provides lasting chronic pain relief but also alters brain regions related to pain generation, new research shows.

In the first randomized controlled test of pain-reprocessing therapy (PRT), two-thirds of patients with chronic back pain (CBP) who received 4 weeks of PRT were pain free or nearly pain free afterward – and for most patients, relief was maintained for 1 year, the researchers found.

“Primary chronic back pain can be dramatically reduced or even eliminated by psychological treatment focused on changing how threatening we perceive the pain to be,” first author Yoni Ashar, PhD, department of psychiatry, Weill Cornell Medicine, New York, said in an interview.

“We were very surprised” by the impact, Dr. Ashar admitted, given that large reductions in pain have rarely been observed in studies that tested psychological therapies for chronic back pain.

The study was published online Sept. 29, 2021, in JAMA Psychiatry.
 

Rethinking pain

CBP is a leading cause of disability, and treatment is often ineffective. In about 85% of cases of primary CBP, a definitive cause of the pain can’t be identified. In these cases, fear, avoidance, and beliefs that pain indicates injury may contribute to ongoing CBP.

PRT educates patients about the role of the brain in generating chronic pain; helps them reappraise their pain as they engage in movements that they had been afraid to undertake; and helps them address emotions that may exacerbate pain.

The study included 151 adults (54% women; mean age, 41 years) who had primary CBP of low to moderate severity (mean pain intensity, 4 of 10) for an average of 10 years.

A total of 50 participants were randomly allocated to undergo PRT (one telehealth session with a physician and eight PRT sessions over 4 weeks), 51 to receive placebo (subcutaneous saline injection in the back), and 50 to continue their routine, usual ongoing care.

Large group differences in pain were observed after treatment. The mean pain score was 1.18 in the PRT group, 2.84 in the placebo group, and 3.13 in the usual-care group. Hedges’ g was –1.14 for PRT versus placebo and –1.74 for PRT versus usual care (P < .001).

Two-thirds (66%) of adults in the PRT group were pain free or nearly pain free following treatment (pain-intensity score of 0 or 1 out of 10), compared with 20% of those in the placebo group and 10% of those who received usual care.

Treatment effects were maintained at 1-year follow-up. The mean pain score was 1.51 in the PRT group, 2.79 in the placebo group, and 3.00 in the usual-care group. Neither age nor sex moderated the effect of PRT on pain intensity.
 

Retraining the brain

The researchers said the effects of PRT on pain were mediated by lessening the belief that pain indicates tissue damage. Of note, PRT also reduced experimentally evoked back pain and spontaneous pain during functional MRI, with large effect sizes.

“The idea is that by thinking about the pain as safe rather than threatening, patients can alter the brain networks reinforcing the pain, and neutralize it,” Dr. Ashar said in a news release.

The authors noted that study participants were relatively well educated and active. The participants reported having longstanding low to moderate pain and disability at baseline.

The physician and therapists were experts in delivering PRT. Future studies should test generalizability to other patient populations, therapists, and treatment contexts.

“Our clinical experience shows that PRT is effective for other primary chronic pain conditions as well,” said Dr. Ashar, including primary knee pain and tension headache.
 

Restoring function

Commenting on the findings, Shaheen E. Lakhan, MD, PhD, neurologist and pain specialist in Newton, Mass., said he has long experience using psychological approaches to address pain, with good results.

“Imagine telling a person suffering from decades of chronic pain that your pain is all in your head. I’ve done that for years as a board-certified pain physician managing only the most severe and debilitating forms of pain. When used to ground brain retraining, I could ultimately restore function to people living with chronic pain,” Dr. Lakhan said.

“The statement is true – the brain ultimately processes signals from throughout the body, forms the perception of pain, and links it to emotional brain centers, among others. Pain is an important survival mechanism so that when your body is at threat of injury, you protect yourself from further damage and withdraw. The problem lies when pain outlasts its welcome and chronifies,” said Dr. Lakhan, senior vice president of research and development of Click Therapeutics in Boston.

The investigators in this study “eloquently prove” that with 4 weeks of PRT, patients can learn that chronic pain is largely a “brain-generated false alarm and that constantly affirming this truth can actually reduce or eliminate it,” Dr. Lakhan said.

“Further, the brain areas implicated with pain are calmed after going through the therapy to both resting pain and pain induced by extending the back,” he noted.

“Pain-reprocessing therapy can improve the lives of chronic [pain patients] who have low to moderate levels of pain and disability; however, much work needs to be done to make this scalable and universally available and covered by insurers as a treatment modality,” Dr. Lakhan added.

He cautioned that he has not seen therapies such as this work when there is significant depression, withdrawal, or lack of control over one’s situation such that one behaves in a helpless manner – “a terrible state of mind called learned helplessness.”

The study was funded by the National Institutes of Health, the National Center for Advancing Translational Sciences, the Radiological Society of North America, the German Research Foundation, the Psychophysiologic Disorders Association, the Foundation for the Study of the Therapeutic Encounter, and community donations. Dr. Ashar received grants from the National Institutes of Health during the conduct of the study and personal fees from UnitedHealth Group, Lin Health, Pain Reprocessing Therapy Center, and Mental Health Partners of Boulder County outside the submitted work. Dr. Lakhan disclosed no relevant financial relationships.

Personalized deep brain stimulation (DBS) appears to rapidly and effectively improve symptoms of treatment-resistant depression, new research suggests.

In a proof-of-concept study, investigators identified specific brain activity patterns responsible for a single patient’s severe depression and customized a DBS protocol to modulate the patterns. Results showed rapid and sustained improvement in depression scores.

“This study points the way to a new paradigm that is desperately needed in psychiatry,” Andrew Krystal, PhD, Weill Institute for Neurosciences, University of California, San Francisco, said in a news release.

“We’ve developed a precision-medicine approach that has successfully managed our patient’s treatment-resistant depression by identifying and modulating the circuit in her brain that’s uniquely associated with her symptoms,” Dr. Krystal added.

The findings were published online Oct. 4 in Nature Medicine.
 

Closed-loop, on-demand stimulation

The patient was a 36-year-old woman with longstanding, severe, and treatment-resistant major depressive disorder. She was unresponsive to multiple antidepressant combinations and electroconvulsive therapy.

The researchers used intracranial electrophysiology and focal electrical stimulation to identify the specific pattern of electrical brain activity that correlated with her depressed mood.

They identified the right ventral striatum – which is involved in emotion, motivation, and reward – as the stimulation site that led to consistent, sustained, and dose-dependent improvement of symptoms and served as the neural biomarker.

In addition, the investigators identified a neural activity pattern in the amygdala that predicted both the mood symptoms, symptom severity, and stimulation efficacy.

The patient was implanted with the Food and Drug Administration–approved NeuroPace RNS System. The device was placed in the right hemisphere. A single sensing lead was positioned in the amygdala and the second stimulation lead was placed in the ventral striatum.

When the sensing lead detected the activity pattern associated with depression, the other lead delivered a tiny dose (1 milliampere/1 mA) of electricity for 6 seconds, which altered the neural activity and relieved mood symptoms.
 

Remission achieved

Once this personalized, closed-loop therapy was fully operational, the patient’s depression score on the Montgomery-Åsberg Depression Rating Scale (MADRS) dropped from 33 before turning treatment ON to 14 at the first ON-treatment assessment carried out after 12 days of stimulation. The score dropped below 10, representing remission, several months later.

The treatment also rapidly improved symptom severity, as measured daily with Hamilton Depression Rating Scale (HAMD-6) and visual analog scales.

“Success was predicated on a clinical mapping stage before chronic device placement, a strategy that has been utilized in epilepsy to map seizure foci in a personalized manner but has not previously been performed in other neuropsychiatric conditions,” the investigators wrote.

This patient represents “one of the first examples of precision psychiatry – a treatment tailored to an individual,” the study’s lead author, Katherine Scangos, MD, also with UCSF Weill Institute, said in an interview.

She added that the treatment “was personally tailored both spatially,” meaning at the brain location, and temporally – the time it was delivered.

“This is the first time a neural biomarker has been used to automatically trigger therapeutic stimulation in depression as a successful long-term treatment,” said Dr. Scangos. However, “we have a lot of work left to do,” she added.

“This study provides proof-of-principle that we can utilize a multimodal brain mapping approach to identify a personalized depression circuit and target that circuit with successful treatment. We will need to test the approach in more patients before we can determine its efficacy,” Dr. Scangos said.
 

First reliable biomarker in psychiatry

In a statement from the UK nonprofit Science Media Centre, Vladimir Litvak, PhD, with the Wellcome Centre for Human Neuroimaging, University College London, said that the study is interesting, noting that it is from “one of the leading groups in the field.”

The fact that depression symptoms can be treated in some patients by electrical stimulation of the ventral striatum is not new, Dr. Litvak said. However, what is “exciting” is that the authors identified a particular neural activity pattern in the amygdala as a reliable predictor of both symptom severity and stimulation effectiveness, he noted.

“Patterns of brain activity correlated with disease symptoms when testing over a large group of patients are commonly discovered. But there are just a handful of examples of patterns that are reliable enough to be predictive on a short time scale in a single patient,” said Dr. Litvak, who was not associated with the research.

“Furthermore, to my knowledge, this is the first example of such a reliable biomarker for psychiatric symptoms. The other examples were all for neurological disorders such as Parkinson’s disease, dystonia, and epilepsy,” he added.

He cautioned that this is a single case, but “if reproduced in additional patients, it will bring at least some psychiatric conditions into the domain of brain diseases that can be characterized and diagnosed objectively rather than based on symptoms alone.”

Dr. Litvak pointed out two other critical aspects of the study: the use of exploratory recordings and stimulation to determine the most effective treatment strategy, and the use of a closed-loop device that stimulates only when detecting the amygdala biomarker.

“It is hard to say based on this single case how important these will be in the future. There is no comparison to constant stimulation that might have worked as well because the implanted device used in the study is not suitable for that,” Dr. Litvak said.

It should also be noted that implanting multiple depth electrodes at different brain sites is a “traumatic invasive procedure only reserved to date for severe cases of drug-resistant epilepsy,” he said. “Furthermore, it only allows [researchers] to test a small number of candidate sites, so it relies heavily on prior knowledge.

“Once clinicians know better what to look for, it might be possible to avoid this procedure altogether by using noninvasive methods,” such as functional MRI or EEG, to match the right treatment option to a patient, Dr. Litvak concluded.

The research was funded by the National Institutes of Health, the Brain & Behavior Research Foundation, and the Ray and Dagmar Dolby Family Fund through the department of psychiatry at UCSF. Dr. Scangos has reported no relevant financial relationships. A complete list of author disclosures is available in the original article. Dr. Litvak is participating in a research funding application to search for electrophysiological biomarkers of depression symptoms using invasive recordings.

Dr. Litvak pointed out two other critical aspects of the study: the use of exploratory recordings and stimulation to determine the most effective treatment strategy, and the use of a closed-loop device that stimulates only when detecting the amygdala biomarker.

“It is hard to say based on this single case how important these will be in the future. There is no comparison to constant stimulation that might have worked as well because the implanted device used in the study is not suitable for that,” Dr. Litvak said.

It should also be noted that implanting multiple depth electrodes at different brain sites is a “traumatic invasive procedure only reserved to date for severe cases of drug-resistant epilepsy,” he said. “Furthermore, it only allows [researchers] to test a small number of candidate sites, so it relies heavily on prior knowledge.

“Once clinicians know better what to look for, it might be possible to avoid this procedure altogether by using noninvasive methods,” such as functional MRI or EEG, to match the right treatment option to a patient, Dr. Litvak concluded.

The research was funded by the National Institutes of Health, the Brain & Behavior Research Foundation, and the Ray and Dagmar Dolby Family Fund through the department of psychiatry at UCSF. Dr. Scangos has reported no relevant financial relationships. A complete list of author disclosures is available in the original article. Dr. Litvak is participating in a research funding application to search for electrophysiological biomarkers of depression symptoms using invasive recordings.

The U.S. Food and Drug Administration has cleared SyncThink’s Eye-Sync technology to aid in the diagnosis of mild traumatic brain injury, the company has announced.

Eye-Sync is a virtual reality eye-tracking platform that provides objective measurements to aid in the assessment of concussion. It’s the first mobile, rapid test for concussion that has been cleared by the FDA, the company said.

As reported by this news organization, Eye-Sync received breakthrough designation from the FDA for this indication in March 2019.

The FDA initially cleared the Eye-Sync platform for recording, viewing, and analyzing eye movements to help clinicians identify visual tracking impairment.

The Eye-Sync technology uses a series of 60-second eye tracking assessments, neurocognitive batteries, symptom inventories, and standardized patient inventories to identify the type and severity of impairment after concussion.

“The platform generates customizable and interpretive reports that support clinical decision making and offers visual and vestibular therapies to remedy deficits and monitor improvement over time,” the company said.

In support of the application for use in concussion, SyncThink enrolled 1,655 children and adults into a clinical study that collected comprehensive patient and concussion-related data for over 12 months.

The company used these data to develop proprietary algorithms and deep learning models to identify a positive or negative indication of concussion.

The study showed that Eye-Sinc had sensitivity greater than 82% and specificity greater than 93%, “thereby providing clinicians with significant and actionable data when evaluating individuals with concussion,” the company said in a news release.

“The outcome of this study very clearly shows the effectiveness of our technology at detecting concussion and definitively demonstrates the clinical utility of Eye-Sinc,” SyncThink Chief Clinical Officer Scott Anderson said in the release.

“It also shows that the future of concussion diagnosis is no longer purely symptom-based but that of a technology driven multi-modal approach,” Mr. Anderson said.

Physiologist David Julius, PhD, University of California San Francisco, and neuroscientist Ardem Patapoutian, PhD, Scripps Research in La Jolla, Calif., have jointly been awarded the 2021 Nobel Prize in Physiology or Medicine for their discoveries of receptors for temperature and touch.

Their discoveries paved the way for new treatments for a wide range of disease conditions, including chronic pain.

“Our ability to sense heat, cold, and touch is essential for survival and underpins our interaction with the world around us,” the Nobel committee, in Stockholm, said in a news release.

“In our daily lives we take these sensations for granted, but how are nerve impulses initiated so that temperature and pressure can be perceived? This question has been solved by this year’s Nobel Prize laureates,” the committee added.
 

Science heats up

Dr. Julius and his collaborators used capsaicin, a pungent compound found in chili peppers that produces a burning sensation, to identify TRPV1, an ion channel activated by painful heat.

“The discovery of TRPV1 was a major breakthrough leading the way to the unravelling of additional temperature-sensing receptors,” the committee said.

Both Dr. Julius and Dr. Patapoutian used menthol to identify another receptor called TRPM8 that is activated by cold. Additional ion channels related to TRPV1 and TRPM8 were identified and found to be activated by a range of different temperatures.

The discoveries fueled other scientists to investigate the roles of these channels in thermal sensation.

“Julius’ discovery of TRPV1 was the breakthrough that allowed us to understand how differences in temperature can induce electrical signals in the nervous system,” the committee noted.
 

Science under pressure

As the mechanisms for temperature sensation began to unravel, Dr. Patapoutian and his collaborators used cultured pressure-sensitive cells to identify an ion channel activated by mechanical stimuli in the skin and internal organs. It was given the name Piezo1, after the Greek word for pressure.

Through its similarity to Piezo1, a second gene was discovered and named Piezo2. Sensory neurons were found to express high levels of Piezo2 and further studies firmly established that Piezo1 and Piezo2 are ion channels that are directly activated by the exertion of pressure on cell membranes.

“The groundbreaking discoveries of the TRPV1, TRPM8, and Piezo channels by this year’s Nobel Prize laureates have allowed us to understand how heat, cold, and mechanical force can initiate the nerve impulses that allow us to perceive and adapt to the world around us,” the Nobel committee said.

Dr. Julius and Dr. Patapoutian will receive a gold medal and share the $1.14 million prize money.

Adults who need to track their blood pressure to find out if they have hypertension prefer to do it at home rather than at a clinic or kiosk or with 24-hour ambulatory BP monitoring (ABPM), according to a new study.

“From a patient-centered perspective, home BP monitoring is the most acceptable method for diagnosing hypertension, although participants were willing to complete ABPM and appreciated its accuracy,” said Beverly Green, MD, MPH, of Kaiser Permanente Washington, Seattle.

Dr. Green presented the study Sept. 29 during the virtual American Heart Association Hypertension Scientific Sessions 2021.

“Health care professionals should work toward relying less on in-clinic visits to diagnose hypertension and supporting their patients in taking their blood pressure measurements at home,” Dr. Green said in an AHA news release.

“Home blood pressure monitoring is empowering and improves our ability to identify and treat hypertension, and to prevent strokes, heart attacks, heart failure, and cardiovascular death,” she added.
 

Convenience is key

The BP-CHECK study was a three-group, randomized, controlled diagnostic study that tested the accuracy and acceptability of office, home, and kiosk BP monitoring against the gold-standard – ABPM – for diagnosing hypertension. Dr. Green presented the results on patient adherence and acceptability of these methods.

Those assigned to clinic measurements were asked to return to the clinic for at least one additional BP check, as is routine in diagnosing hypertension in clinical practice.

Those in the home group were given and trained to use a Bluetooth/web-enabled home BP monitor and were asked to take their BP twice a day (morning and evening, with two measurements each time) for 5 days.

Those in the kiosk group were trained to use a BP kiosk with a smart card and were asked to return to the kiosk (or a nearby pharmacy with the same kiosk) on 3 separate days and measure their BP three times at each visit.

All participants were asked to complete their group-assigned diagnostic regimens in 3 weeks and then to complete 24-hour ABPM.

The trial enrolled 510 adults who presented to Kaiser Permanente Washington primary care clinics with elevated BP (mean, 150/88 mm Hg) but who had not yet been diagnosed with hypertension. Their mean age was 59 years, 80% of the study participants were White, and 51% were male.

Adherence to the monitoring regimen was highest in the home BP group (90.6%), followed by the clinic group (87.2%), and lowest in the kiosk group (67.9%). Adherence to ABPM among all participants was 91.6%.

Overall, acceptability was highest for the home BP group, followed by the clinic and kiosk groups; 24-hour ABPM monitoring was the least acceptable option.

Home was the “overwhelming” stated preference when asked before randomization and after, Dr. Green said.

The findings come as no surprise to Willie Lawrence Jr., MD, head of the AHA National Hypertension Control Initiative oversight committee. “Patients will do what’s most convenient for them,” he told this news organization.

“We know from other studies that really all you need to do is measure the blood pressure twice a day for 3 days. That will give you a good idea what that patient’s blood pressure is as it relates to future cardiac events,” said Dr. Lawrence, who wasn’t involved in the study.

“We should really begin to focus more on these home, self-measured blood pressures using validated devices, and that’s important because a lot of the devices out there aren’t validated,” he explained.

“Patients with hypertension should have a blood pressure monitor at home that is validated and should be instructed in how to use it properly,” Dr. Lawrence concluded.

Funding for the study was provided by the Patient-Centered Outcomes Research Institute. Dr. Green and Dr. Lawrence have no relevant disclosures.

Adults with diabetes whose blood pressure does not drop as expected at night (nondipping), or whose BP increases during the night (reverse dipping) are at higher risk of dying than peers with normal nighttime BP patterns, a longitudinal study has shown.

“Reverse dippers have more than double the risk of death for any cause over 20 years, irrespective of blood pressure control,” study investigator Martina Chiriacò, MD, University of Pisa (Italy), said in an interview.

“Primary physicians and diabetologists should look for abnormal blood pressure dipping patterns in patients with diabetes through 24-hour ambulatory blood pressure monitoring,” she added.

Dr. Chiriacò presented the research Sept. 28 at the joint scientific sessions of the American Heart Association Council on Hypertension, AHA Council on Kidney in Cardiovascular Disease, and American Society of Hypertension.
 

Scarce data

Previous studies have shown that a nondipping BP pattern is linked to renal and cardiovascular disease, both in healthy individuals and in patients with hypertension or diabetes.

“Nevertheless, the long-term effect of nondipping on mortality in diabetes is still unclear; in particular, data on reverse dippers are extremely scarce,” Dr. Chiriacò explained.

To investigate, the researchers analyzed data on 349 adults with diabetes (81% type 2 diabetes) who were followed for more than 2 decades as part of the CHAMPION study, all with available 24-hour ambulatory BP monitoring (ABPM) and heart rate variability monitoring.

Dipping, nondipping, and reverse dipping were defined as a decline of at least 10%, a decline of less than 10%, and an increase of at least 0.1% in average night-time systolic BP, compared with average daytime SBP, respectively.

The cohort involved 166 (47.6%) dippers, 144 (41.2%) nondippers, and 39 (11.2%) reverse dippers.

Compared with dippers, nondippers and reverse dippers showed a progressively higher prevalence of cardiac autonomic neuropathy, low heart rate variability, 24-hour hypertension, isolated nocturnal hypertension, postural hypotension, and lower prevalence of white-coat hypertension.

During a median follow-up of 21 years, 136 patients died (39%). 

Compared with dippers, reverse dippers and nondippers had an average reduction in survival of 2.5 years and 1.1 years, respectively, Dr. Chiriacò reported.

During follow-up, risk for all-cause mortality was about twofold higher for reverse dippers than for dippers (adjusted hazard ratio, 2.2; 95% confidence interval, 1.3-3.8; P = .003) and than for nondippers (adjusted HR, 1.8; 95% CI, 1.1-2.9; P = .34).

There was no significant difference in all-cause mortality risk between dippers and nondippers.

Notably, said Dr. Chiriacò, the one in five patients with isolated nocturnal hypertension had a reduction in survival similar to that seen in individuals with 24-hour sustained hypertension (average, 1.2 years).

Individuals with low heart rate variability over 24 hours had an average reduction in survival of 1.8 years.
 

Important underused diagnostic tool

“We believe that our study is important since it is the only available study with a follow-up longer than 20 years that explores the role of blood pressure patterns and heart rate variability as risk factors for all-cause mortality in diabetes,” Dr. Chiriacò said in an interview.

There are some available strategies to reduce BP during the night, she added. “The most tested and effective is the administration of anti-hypertensive medications in the evening rather than in the morning.”

Weighing in on the study, Maryann McLaughlin, MD, cardiologist at Mount Sinai Hospital, New York, said: “Interestingly, most physicians do not do 24-hour ambulatory blood pressure monitoring when they’re making the diagnosis of hypertension.”

“And really, the correct way to make a diagnosis of hypertension and rule out white-coat hypertension is either with a 24-hour ambulatory blood pressure monitor or use of home blood pressure monitors,” she said in an interview.

“The 24-hour ambulatory blood pressure monitor is an important diagnostic tool and a great way to really look at this issue of dipping, which is a very important physiologic parameter,” Dr. McLaughlin said.

“In our offices, we offer the 24-hour home ambulatory blood pressure monitor routinely. Most patients are receptive to it and they usually tolerate it pretty well,” Dr. McLaughlin said.

The study was funded by the University of Pisa. Dr. Chiriacò and Dr. McLaughlin have no relevant disclosures.

“In our offices, we offer the 24-hour home ambulatory blood pressure monitor routinely. Most patients are receptive to it and they usually tolerate it pretty well,” Dr. McLaughlin said.

The study was funded by the University of Pisa. Dr. Chiriacò and Dr. McLaughlin have no relevant disclosures.

Adults with diabetes whose blood pressure does not drop as expected at night (nondipping), or whose BP increases during the night (reverse dipping) are at higher risk of dying than peers with normal nighttime BP patterns, a longitudinal study has shown.

“Reverse dippers have more than double the risk of death for any cause over 20 years, irrespective of blood pressure control,” study investigator Martina Chiriacò, MD, University of Pisa (Italy), said in an interview.

“Primary physicians and diabetologists should look for abnormal blood pressure dipping patterns in patients with diabetes through 24-hour ambulatory blood pressure monitoring,” she added.

Dr. Chiriacò presented the research Sept. 28 at the joint scientific sessions of the American Heart Association Council on Hypertension, AHA Council on Kidney in Cardiovascular Disease, and American Society of Hypertension.
 

Scarce data

Previous studies have shown that a nondipping BP pattern is linked to renal and cardiovascular disease, both in healthy individuals and in patients with hypertension or diabetes.

“Nevertheless, the long-term effect of nondipping on mortality in diabetes is still unclear; in particular, data on reverse dippers are extremely scarce,” Dr. Chiriacò explained.

To investigate, the researchers analyzed data on 349 adults with diabetes (81% type 2 diabetes) who were followed for more than 2 decades as part of the CHAMPION study, all with available 24-hour ambulatory BP monitoring (ABPM) and heart rate variability monitoring.

Dipping, nondipping, and reverse dipping were defined as a decline of at least 10%, a decline of less than 10%, and an increase of at least 0.1% in average night-time systolic BP, compared with average daytime SBP, respectively.

The cohort involved 166 (47.6%) dippers, 144 (41.2%) nondippers, and 39 (11.2%) reverse dippers.

Compared with dippers, nondippers and reverse dippers showed a progressively higher prevalence of cardiac autonomic neuropathy, low heart rate variability, 24-hour hypertension, isolated nocturnal hypertension, postural hypotension, and lower prevalence of white-coat hypertension.

During a median follow-up of 21 years, 136 patients died (39%). 

Compared with dippers, reverse dippers and nondippers had an average reduction in survival of 2.5 years and 1.1 years, respectively, Dr. Chiriacò reported.

During follow-up, risk for all-cause mortality was about twofold higher for reverse dippers than for dippers (adjusted hazard ratio, 2.2; 95% confidence interval, 1.3-3.8; P = .003) and than for nondippers (adjusted HR, 1.8; 95% CI, 1.1-2.9; P = .34).

There was no significant difference in all-cause mortality risk between dippers and nondippers.

Notably, said Dr. Chiriacò, the one in five patients with isolated nocturnal hypertension had a reduction in survival similar to that seen in individuals with 24-hour sustained hypertension (average, 1.2 years).

Individuals with low heart rate variability over 24 hours had an average reduction in survival of 1.8 years.
 

Important underused diagnostic tool

“We believe that our study is important since it is the only available study with a follow-up longer than 20 years that explores the role of blood pressure patterns and heart rate variability as risk factors for all-cause mortality in diabetes,” Dr. Chiriacò said in an interview.

There are some available strategies to reduce BP during the night, she added. “The most tested and effective is the administration of anti-hypertensive medications in the evening rather than in the morning.”

Weighing in on the study, Maryann McLaughlin, MD, cardiologist at Mount Sinai Hospital, New York, said: “Interestingly, most physicians do not do 24-hour ambulatory blood pressure monitoring when they’re making the diagnosis of hypertension.”

“And really, the correct way to make a diagnosis of hypertension and rule out white-coat hypertension is either with a 24-hour ambulatory blood pressure monitor or use of home blood pressure monitors,” she said in an interview.

“The 24-hour ambulatory blood pressure monitor is an important diagnostic tool and a great way to really look at this issue of dipping, which is a very important physiologic parameter,” Dr. McLaughlin said.

Adherence to the MIND diet can improve memory and thinking skills of older adults, even in the presence of Alzheimer’s disease pathology, new data from the Rush Memory and Aging Project (MAP) show.

Suprijono Suharjoto/Fotolia

“The MIND diet was associated with better cognitive functions independently of brain pathologies related to Alzheimer’s disease, suggesting that diet may contribute to cognitive resilience, which ultimately indicates that it is never too late for dementia prevention,” lead author Klodian Dhana, MD, PhD, with the Rush Institute of Healthy Aging at Rush University, Chicago, said in an interview.

The study was published online Sept. 14, 2021, in the Journal of Alzheimer’s Disease.
 

Impact on brain pathology

“While previous investigations determined that the MIND diet is associated with a slower cognitive decline, the current study furthered the diet and brain health evidence by assessing the impact of brain pathology in the diet-cognition relationship,” Dr. Dhana said.

The MIND diet was pioneered by the late Martha Clare Morris, ScD, a Rush nutritional epidemiologist, who died in 2020 of cancer at age 64. A hybrid of the Mediterranean and DASH (Dietary Approaches to Stop Hypertension) diets, the MIND diet includes green leafy vegetables, fish, nuts, berries, beans, and whole grains and limits consumption of fried and fast foods, sweets, and pastries.

The current study focused on 569 older adults who died while participating in the MAP study, which began in 1997. Participants in the study were mostly White and were without known dementia. All of the participants agreed to undergo annual clinical evaluations. They also agreed to undergo brain autopsy after death.

Beginning in 2004, participants completed annual food frequency questionnaires, which were used to calculate a MIND diet score based on how often the participants ate specific foods.

The researchers used a series of regression analyses to examine associations of the MIND diet, dementia-related brain pathologies, and global cognition near the time of death. Analyses were adjusted for age, sex, education, apo E4, late-life cognitive activities, and total energy intake.

The results show that a higher MIND diet score was associated with better global cognitive functioning around the time of death (beta, 0.119; P = .003).

Notably, the researchers said, neither the strength nor the significance of association changed markedly when AD pathology and other brain pathologies were included in the model (beta, 0.111; P = .003).

The relationship between better adherence to the MIND diet and better cognition remained significant when the analysis was restricted to individuals without mild cognitive impairment at baseline (beta, 0.121; P = .005) as well as to persons in whom a postmortem diagnosis of AD was made on the basis of NIA-Reagan consensus recommendations (beta, 0.114; P = .023).

The limitations of the study include the reliance on self-reported diet information and a sample made up of mostly White volunteers who agreed to annual evaluations and postmortem organ donation, thus limiting generalizability.

Strengths of the study include the prospective design with annual assessment of cognitive function using standardized tests and collection of the dietary information using validated questionnaires. Also, the neuropathologic evaluations were performed by examiners blinded to clinical data.

“Diet changes can impact cognitive functioning and risk of dementia, for better or worse. There are fairly simple diet and lifestyle changes a person could make that may help to slow cognitive decline with aging and contribute to brain health,” Dr. Dhana said in a news release.
 

Builds resilience

Weighing in on the study, Heather Snyder, PhD, vice president of medical and scientific relations for the Alzheimer’s Association, said this “interesting study sheds light on the impact of nutrition on cognitive function.

“The findings add to the growing literature that lifestyle factors – like access to a heart-healthy diet – may help the brain be more resilient to disease-specific changes,” Snyder said in an interview.

“The Alzheimer’s Association’s US POINTER study is investigating how lifestyle interventions, including nutrition guidance, like the MIND diet, may impact a person’s risk of cognitive decline. An ancillary study of the US POINTER will include brain imaging to investigate how these lifestyle interventions impact the biology of the brain,” Dr. Snyder noted.

The research was supported by the National Institute on Aging of the National Institutes of Health. Dr. Dhana and Dr. Snyder disclosed no relevant financial relationships.

Sexual harassment or assault during military service among young and middle-aged veterans is associated with an increased risk for hypertension, a new study suggests.

“Understanding a patient’s trauma history is invaluable for treating the whole person,” Allison E. Gaffey, PhD, Yale University, New Haven, Conn., and the Veterans Affairs Connecticut Healthcare System, told this news organization.

“Assessing men and women’s history of trauma, including sexual trauma, is critical for recognizing nontraditional factors that contribute to their cardiovascular risk and to gain a more comprehensive understanding of their mental and physical health,” Dr. Gaffey added.

She presented her research at the joint scientific sessions of the American Heart Association Council on Hypertension, AHA Council on Kidney in Cardiovascular Disease, and American Society of Hypertension.
 

Lasting impact on physical health

Dr. Gaffey and colleagues analyzed data from the VA for roughly 1.2 million veterans (mean age, 30.2 years; 12% female) who were discharged from the military after Sept. 30, 2001, and who received health care services at VA medical centers from 2001 to 2017. 

All were screened for sexual harassment and assault, known as military sexual trauma (MST), when they first began receiving VA care.

During 16 years of follow-up, 33,881 veterans screened positive for MST (65% women), and 307,332 developed hypertension (15% women).

Overall, MST was associated with a 30% increase in risk for incident hypertension in unadjusted models (hazard ratio, 1.30; 95% confidence interval, 1.28-1.33; P < .001).

After adjustment for demographic characteristics, lifestyle factors, cardiovascular comorbidities, PTSD, anxiety, and depression, MST remained significantly associated with hypertension (adjusted HR, 1.10; 95% CI, 1.08-1.12; P < .001).

When women and men were examined separately, the link between MST and risk for hypertension remained for both groups, but was slightly stronger among women.

“Sexual trauma has been associated with autonomic dysfunction, inflammation, and dysregulation in the hypothalamic pituitary adrenal axis and renin-angiotensin-aldosterone system, which could lead to elevations in BP over time,” Dr. Gaffey told this news organization.

“These findings show that even many years after being discharged from military service, exposure to military sexual trauma can continue to significantly influence veterans’ physical health,” she added.

Dr. Gaffey said it will be important to determine if early treatment of MST improves hypertension risk, particularly among those showing elevated blood pressure or stage 1 hypertension.
 

Social determinants of health

Willie Lawrence Jr., MD, head of the AHA National Hypertension Control Initiative oversight committee, said the findings in this study are “in line with what we know about the impact of social determinants of health on high blood pressure.”

“There are studies that suggest that things that we historically don’t look at as risk factors for hypertension – lifelong racism, crime, mental health status – do in fact predict your risk of developing hypertension,” Dr. Lawrence, from Spectrum Health in Benton Harbor, Mich., told this news organization.

“It’s not just your genetics that will determine your health, and there are a lot of things that will affect your blood pressure. Your blood pressure is really just a barometer of everything that’s going on in your life and some of the things that have gone on in your life in the past,” added Dr. Lawrence, who wasn’t involved in the study.

Funding for the study was provided by the Department of Veterans Affairs. Dr. Gaffey and Dr. Lawrence have no relevant disclosures.

Results of a phase 3 study show that treatment with lumateperone (Caplyta) significantly improved depressive symptoms for patients with major depressive episodes associated with both bipolar I and bipolar II disorders.

“Bipolar depression represents the most prevalent and debilitating presentation of bipolar disorder. There is a critical need for more treatments that are effective and have favorable safety profiles,” study investigator Gary S. Sachs, MD, associate clinical professor in psychiatry, Harvard Medical School, Boston, said in a company news release.

“The strong efficacy and impressive safety results reported in this trial for a broad patient population position lumateperone as a potentially important advancement in the treatment of this disorder,” said Dr. Sachs, who is also founding director of the Bipolar Clinic and Research Program at Massachusetts General Hospital, Boston.

The findings were published online September 23 in the American Journal of Psychiatry.
 

First-in-class antipsychotic

Lumateperone is a first-in-class antipsychotic that acts synergistically through the serotonergic, dopaminergic, and glutamatergic systems.

It was approved by the U.S. Food and Drug Administration in late 2019 for the treatment of adults with schizophrenia, as reported at the time by this news organization.

The current study included 377 patients who had received a clinical diagnosis of bipolar I or bipolar II disorder and were subject to major depressive episodes. All were randomly allocated in a 1:1 ratio to receive 6 weeks of lumateperone monotherapy at 42 mg/d or matching placebo.

At day 43, lumateperone treatment was associated with significantly greater improvement from baseline in Montgomery-Åsberg Depression Rating Scale (MADRS) score in comparison with placebo (drug-placebo difference, -4.6 points; P < .0001; effect size = -0.56), which met the study’s primary endpoint.

The study drug led to significant improvement in MADRS total score as early as the first week, which was the first time point measured. Improvement continued throughout the study.

Treatment with lumateperone also led to significantly greater improvement in the key secondary endpoints of total score on the severity scale of the Clinical Global Impressions Scale–Bipolar Version (CGI-BP-S) (P < .0001; effect size = -0.46) and the CGI-BP-S depression score (P < .001; effect size = -50).

In addition, it was superior to placebo both for patients with bipolar I disorder and those with bipolar II disorder.

Somnolence and nausea were the most commonly reported adverse events associated with lumateperone. Minimal changes were observed in weight and vital signs and in results of metabolic or endocrine assessments. These findings are in line with previous studies involving patients with schizophrenia.

The incidence of extrapyramidal symptom–related events was low and was similar to those with placebo.

The company has submitted a supplemental new drug application for lumateperone for the treatment of bipolar depression, which is currently under review with the FDA. The target action date is December 17.

Results of a phase 3 study show that treatment with lumateperone (Caplyta) significantly improved depressive symptoms for patients with major depressive episodes associated with both bipolar I and bipolar II disorders.

“Bipolar depression represents the most prevalent and debilitating presentation of bipolar disorder. There is a critical need for more treatments that are effective and have favorable safety profiles,” study investigator Gary S. Sachs, MD, associate clinical professor in psychiatry, Harvard Medical School, Boston, said in a company news release.

“The strong efficacy and impressive safety results reported in this trial for a broad patient population position lumateperone as a potentially important advancement in the treatment of this disorder,” said Dr. Sachs, who is also founding director of the Bipolar Clinic and Research Program at Massachusetts General Hospital, Boston.

The findings were published online September 23 in the American Journal of Psychiatry.
 

First-in-class antipsychotic

Lumateperone is a first-in-class antipsychotic that acts synergistically through the serotonergic, dopaminergic, and glutamatergic systems.

It was approved by the U.S. Food and Drug Administration in late 2019 for the treatment of adults with schizophrenia, as reported at the time by this news organization.

The current study included 377 patients who had received a clinical diagnosis of bipolar I or bipolar II disorder and were subject to major depressive episodes. All were randomly allocated in a 1:1 ratio to receive 6 weeks of lumateperone monotherapy at 42 mg/d or matching placebo.

At day 43, lumateperone treatment was associated with significantly greater improvement from baseline in Montgomery-Åsberg Depression Rating Scale (MADRS) score in comparison with placebo (drug-placebo difference, -4.6 points; P < .0001; effect size = -0.56), which met the study’s primary endpoint.

The study drug led to significant improvement in MADRS total score as early as the first week, which was the first time point measured. Improvement continued throughout the study.

Treatment with lumateperone also led to significantly greater improvement in the key secondary endpoints of total score on the severity scale of the Clinical Global Impressions Scale–Bipolar Version (CGI-BP-S) (P < .0001; effect size = -0.46) and the CGI-BP-S depression score (P < .001; effect size = -50).

In addition, it was superior to placebo both for patients with bipolar I disorder and those with bipolar II disorder.

Somnolence and nausea were the most commonly reported adverse events associated with lumateperone. Minimal changes were observed in weight and vital signs and in results of metabolic or endocrine assessments. These findings are in line with previous studies involving patients with schizophrenia.

The incidence of extrapyramidal symptom–related events was low and was similar to those with placebo.

The company has submitted a supplemental new drug application for lumateperone for the treatment of bipolar depression, which is currently under review with the FDA. The target action date is December 17.

The U.S. Drug Enforcement Administration has issued a public safety alert over an “alarming” increase in fake prescription pills laced with the synthetic opioid fentanyl or the stimulant methamphetamine.

“The United States is facing an unprecedented crisis of overdose deaths fueled by illegally manufactured fentanyl and methamphetamine,” DEA Administrator Anne Milgram said in the alert.

“Counterfeit pills that contain these dangerous and extremely addictive drugs are more lethal and more accessible than ever before. DEA is focusing resources on taking down the violent drug traffickers causing the greatest harm and posing the greatest threat to the safety and health of Americans,” Ms. Milgram said.

Criminal drug networks are mass-producing fake fentanyl- and methamphetamine-laced pills and deceptively marketing them as legitimate prescription pills, the DEA warns.

These lethal counterfeit pills are made to look like legitimate prescription opioid medications such as oxycodone (Oxycontin, Percocet), hydrocodone (Vicodin), and alprazolam (Xanax); or stimulants like amphetamines (Adderall).

The agency has seized fake pills in every U.S. state. More than 9.5 million fake pills have been seized so far this year – more than the last 2 years combined.

The number of seized counterfeit pills with fentanyl has jumped nearly 430% since 2019. DEA lab tests reveal that two out of every five pills with fentanyl contain a potentially lethal dose.

These deadly pills are widely accessible and often sold on social media and e-commerce platforms – making them available to anyone with a smartphone, including minors, the DEA warns.

More than 93,000 people died of a drug overdose in the United States last year, according to federal statistics, and fentanyl is the primary driver of this alarming increase in overdose deaths, the DEA says.

The agency has launched a “One Pill Can Kill” public awareness campaign to educate the public of the dangers of counterfeit pills purchased outside of a licensed pharmacy. These pills are “illegal, dangerous, and potentially lethal,” the DEA warns.

This alert does not apply to legitimate pharmaceutical medications prescribed by doctors and dispensed by licensed pharmacists, the DEA says.

“The legitimate prescription supply chain is not impacted. Anyone filling a prescription at a licensed pharmacy can be confident that the medications they receive are safe when taken as directed by a medical professional,” the agency says.
