‘COVID toes’ chilblain-like lesions not related to COVID-19
from Italy.
These lesions are “most likely are benign” and resolve on their own after 2-6 weeks, Valentina Discepolo, MD, PhD, University of Naples Federico II, told this news organization.
“They do not seem to be the manifestation of systemic inflammatory or autoimmune phenomena. According to our experience, they should not require a SARS-CoV-2–specific molecular or serological test since in all cases in our series they were negative,” said Dr. Discepolo.
The study was published online June 10, 2021, in JAMA Network Open.
‘COVID toes’ a fallacy?
The temporal association between the COVID-19 pandemic and the increasing number of chilblain-like lesions has led some in the media to call it “COVID toes,” the investigators wrote. However, data on the association with SARS-CoV-2 are controversial.
For this report, Dr. Discepolo and colleagues evaluated 17 adolescents who presented with chilblain-like lesions of the toes during the first wave of the pandemic in southern Italy.
None had evidence of current, past, or local SARS-CoV-2 infection.
“In our experience, chilblain-like lesions are not a manifestation of COVID-19, as shown by negative serological and molecular specific for SARS-CoV2,” Dr. Discepolo said in an interview.
The lesions were bilaterally distributed in 16 adolescents (94.1%) and heel skin was involved in 7 (41.2%). Ulceration complicated one patient during the active phase of the disease, and desquamation developed over time in three patients (17.6%). Only two patients (11.8%) had concurrent involvement of the fingers.
Self-administered therapies included topical antibiotics and/or corticosteroids, disinfectants, and antifungal agents; systemic antibiotics or corticosteroids were used rarely.
None of the therapies substantially changed the course of the lesions. Duration was “extremely variable,” ranging from 49 to 145 days; however, at follow-up, all patients had full resolution.
Almost invariably, the lesions were characterized by a triad of red dots, white rosettes, and white streaks on an erythematous background, the investigators reported.
In more than half the patients (56%), red dots often appeared as dotted and comma-shaped congested vessels that surrounded the rosettes in the early stage of the lesions. In later stages, red dots were still present, but the rosettes had disappeared.
Although found inconsistently in inflammatory cutaneous conditions, these three signs do not characterize the dermoscopic picture of perniosis, suggesting a distinct disease process, the investigators said.
Don’t blame it on ischemia, clots
Histologic analysis revealed “remodeling of the dermal blood vessels with a lobular arrangement, wall thickening, and a mild perivascular lymphocytic infiltrate,” they noted.
Punch biopsy of the involved skin mostly showed endothelial hyperplasia, mild lymphocytic infiltrate, and vessels’ architecture disruption with no papillary dermal edema or eosinophilic or neutrophilic infiltrate.
Pathology did not reveal any ischemic changes, which argues against systemic vasculopathy, Farzam Gorouhi, MD, from Kaiser Permanente, South Sacramento Medical Center, noted in a linked editorial. “Thus, this study provides further evidence against the thromboembolic nature of the presented pattern in adolescents during the COVID-19 pandemic.”
Results of capillaroscopy, used to investigate structural changes in peripheral microcirculation, were either completely normal or showed rare ectasias, supporting a lack of systemic inflammatory process.
“The lack of capillaroscopic features of a major vasculopathic event in the study by Discepolo et al. argues against the ischemic nature of this disease and, thus, indicates that this presentation is not associated with systemic ischemia or an embolic event,” Dr. Gorouhi noted.
Chilblain-like lesions have been one of the most commonly described cutaneous manifestations during the COVID-19 pandemic, but their etiopathogenesis, including the role of SARS-CoV-2, has remained elusive, the investigators wrote.
The findings in this case series do not support the association of the lesions with SARS-CoV-2 infection, they concluded.
The fact that only three new cases of chilblain-like lesions were reported during the highest peaks of the pandemic further supports a lack of association with SARS-CoV-2 infection, they noted.
In addition, none of these patients tested positive for SARS-CoV-2 and all three cases during the second wave occurred in the winter months, suggesting that exposure to the cold might, at least in some cases, trigger the skin lesions, the investigators said.
In line with this hypothesis, seven of the adolescents in this case series (41.2%) relapsed during the winter months while again testing negative for SARS-CoV-2.
“We believe that lifestyle modifications [reduced physical activity, microtraumatisms caused by walking barefoot at home] during the first strict lockdown played a role, likely promoting a local inflammatory process promoted by vascular stasis that led in genetically susceptible individuals to the onset of these lesions,” Dr. Discepolo said in an interview.
This research had no specific funding. The investigators and Dr. Gorouhi declared no relevant conflicts of interest.

AHA: Physical activity best first-line for high BP, cholesterol
The optimal first step to address mild to moderately elevated blood pressure and cholesterol in otherwise healthy adults is a “prescription” to sit less and move more, the American Heart Association says in a new scientific statement.
“The current American Heart Association guidelines for diagnosing high blood pressure and cholesterol recognize that otherwise healthy individuals with mildly or moderately elevated levels of these cardiovascular risk factors should actively attempt to reduce these risks,” Bethany Barone Gibbs, PhD, chair of the statement writing group, said in an AHA news release.
“The first treatment strategy for many of these patients should be healthy lifestyle changes beginning with increasing physical activity,” said Dr. Gibbs, from the University of Pittsburgh.
The 12-page AHA scientific statement – Physical Activity as a Critical Component of First-Line Treatment for Elevated Blood Pressure or Cholesterol: Who, What, and How? – was published online June 2 in Hypertension.
Every little bit helps
According to the AHA, about 21% of American adults have systolic blood pressure between 120 and 139 mm Hg, or diastolic blood pressure between 80 and 89 mm Hg, which meets the criteria for lifestyle-only treatment for elevated BP outlined in the American College of Cardiology (ACC)/AHA high blood pressure guideline.
In addition, about 28% of American adults have LDL cholesterol above 70 mg/dL and otherwise meet the low-risk criteria for heart disease or stroke. These individuals would meet the criteria for lifestyle-only treatment outlined in the 2018 ACC/AHA cholesterol treatment guidelines, which include increased physical activity, weight loss, better diet, smoking cessation, and moderating alcohol intake.
“Of the recommended lifestyle changes, increasing physical activity has extensive benefits, including improving both blood pressure and blood cholesterol, that are comparable, superior, or complementary to other healthy lifestyle changes,” the writing group says.
“Physical activity assessment and prescription are an excellent lifestyle behavior treatment option for all patients, including for the large population of mild-moderate-risk patients with elevated blood pressure and blood cholesterol,” they note.
Research has shown that increasing physical activity can lead to clinically meaningful 3 or 4 mm Hg reductions in systolic and diastolic blood pressure, and 3 to 6 mg/dL decreases in LDL cholesterol, the authors point out.
Previous evidence also shows that physically active people have a 21% lower risk of developing cardiovascular disease and a 36% lower risk for death from cardiovascular diseases than those who are not physically active.
Physical activity also has benefits beyond heart health, including a lower risk for some cancers; improved bone, brain, and mental health; and better sleep, they note.
The U.S. Department of Health and Human Services 2018 physical activity guidelines advise Americans to log 150 minutes of moderate-intensity aerobic exercise or 75 minutes of vigorous aerobic activity each week and to participate in two or more weekly strength training sessions.
However, there is no minimum amount of time to receive benefits from physical activity.
“Every little bit of activity is better than none. Even small initial increases of 5 to 10 minutes a day can yield health benefits,” Dr. Gibbs said.
Translational advice for clinicians
The AHA statement encourages clinicians to ask patients about their physical activity at every interaction; provide ideas and resources to help patients improve and sustain regular life-long physical activity; and encourage and celebrate small increases in activity, such as walking more or taking the stairs, to help with motivation.
“In our world where physical activity is increasingly engineered out of our lives and the overwhelming default is to sit – and even more so now as the nation and the world is practicing quarantine and isolation to reduce the spread of coronavirus – the message that we must be relentless in our pursuit to ‘sit less and move more’ throughout the day is more important than ever,” said Dr. Gibbs.
The statement was prepared by a volunteer writing group on behalf of the AHA Council on Lifestyle and Cardiometabolic Health; the Council on Cardiovascular and Stroke Nursing; and the Council on Clinical Cardiology.
This research had no commercial funding. A list of disclosures for the writing group is available with the original article.

Cortical thinning in adolescence ‘definitively’ tied to subsequent psychosis
Subtle differences in brain morphometric features present in adolescence were associated with the subsequent development of psychosis in what is believed to be the largest neuroimaging investigation to date involving people at clinical high risk (CHR).
Investigators found widespread lower cortical thickness (CT) in individuals at CHR, consistent with previously reported CT differences in individuals with an established psychotic disorder.
“This is the first study to definitively show that there are subtle, widespread structural brain differences in high-risk youth before they develop psychosis,” study investigator Maria Jalbrzikowski, PhD, assistant professor of psychiatry, University of Pittsburgh, said in an interview.
The findings also suggest that there are developmental periods during which certain brain abnormalities may be more apparent, “highlighting the need to consider developmental period when developing objective, biological risk factors for early intervention in psychosis,” Dr. Jalbrzikowski said.
The study was published online May 5 in JAMA Psychiatry.
‘Sobering’ results
The findings are based on pooled structural MRI scans from 3,169 individuals recruited at 31 international sites participating in the Enhancing Neuro Imaging Genetics Through Meta-Analysis (ENIGMA) Clinical High Risk for Psychosis Working Group.
Forty-five percent of the participants were female; the mean age was 21 years (range, 9.5 to 39.9 years).
The cohort included 1,792 individuals at CHR for psychosis and 1,377 healthy control persons. Using longitudinal clinical information, the researchers identified 253 individuals at CHR who went on to develop a psychotic disorder (CHR-PS+) and 1,234 at CHR who did not develop a psychotic disorder (CHR-PS-). For the remaining 305 individuals at CHR, follow-up data were unavailable.
Compared with healthy control persons, individuals at CHR had widespread lower CT measures but not lower surface area or subcortical volume. Lower CT measures in the fusiform, superior temporal, and paracentral regions were associated with conversion to psychosis.
The pattern of differences in cortical thickness in those in the CHR-PS+ group mirrored patterns seen in people with schizophrenia and in people with 22q11.2 microdeletion syndrome who developed a psychotic disorder.
The researchers note that although all individuals experience cortical thinning as they move into adulthood, in their study, cortical thinning was already present in participants aged 12 to 16 years who developed psychosis.
“We don’t yet know exactly what this means, but adolescence is a critical time in a child’s life – it’s a time of opportunity to take risks and explore, but also a period of vulnerability,” Dr. Jalbrzikowski said in a news release.
“We could be seeing the result of something that happened even earlier in brain development but only begins to influence behavior during this developmental stage,” she noted.
This analysis represents the largest-ever pooling of brain scans in children and young adults who were determined by psychiatric assessment to be at high risk of developing psychosis.
“These results were, in a sense, sobering. On the one hand, our dataset includes 600% more high-risk youth who developed psychosis than any existing study, allowing us to see statistically significant results in brain structure.”
“But the variance between whether or not a high-risk youth develops psychosis is so small that it would be impossible to see a difference at the individual level,” Dr. Jalbrzikowski said.
More work is needed in order for the findings to be translated into clinical care, she added.
Definitive findings
Commenting on the findings for an interview, Russell Margolis, MD, clinical director, Johns Hopkins Schizophrenia Center, said that “it’s not so much that the findings are novel but rather that they’re fairly definitive in that this is by far the largest study of its kind looking at this particular question, and that gives it power. The problem with imaging studies has often been inconsistent results from study to study because of small sample size.”
“In order to see these differences in a robust way, you need a large sample size, meaning that for any one individual, this kind of structural imaging is not going to add much to the prediction of whether someone will eventually develop a schizophrenia-like illness,” said Dr. Margolis, professor of psychiatry and behavioral sciences, Johns Hopkins University, Baltimore.
From a clinical standpoint,
“The predominant hypothesis in the field is that early developmental abnormalities are the root cause of schizophrenia and related disorders, and this study is consistent with that, particularly the age-related differences, which are suggestive of neurodevelopmental abnormalities preceding the development of overt symptoms, which many other findings have also suggested,” Dr. Margolis said.
“Abnormalities in cortical thickness could be from a number of different neurobiological processes, and research into those processes are worth investigating,” he added.
The researchers received support from numerous funders, all of which are listed in the original article, along with author disclosures for ENIGMA working group members. Dr. Margolis has disclosed no relevant financial relationships.

“In order to see these differences in a robust way, you need a large sample size, meaning that for any one individual, this kind of structural imaging is not going to add much to the prediction of whether someone will eventually develop a schizophrenia-like illness,” said Dr. Margolis, professor of psychiatry and behavioral sciences, Johns Hopkins University, Baltimore.
From a clinical standpoint,
“The predominant hypothesis in the field is that early developmental abnormalities are the root cause of schizophrenia and related disorders, and this study is consistent with that, particularly the age-related differences, which are suggestive of neurodevelopmental abnormalities preceding the development of overt symptoms, which many other findings have also suggested,” Dr. Margolis said.
“Abnormalities in cortical thickness could be from a number of different neurobiological processes, and research into those processes are worth investigating,” he added.
The researchers received support from numerous funders, all of which are listed in the original article, along with author disclosures for ENIGMA working group members. Dr. Margolis has disclosed no relevant financial relationships.

Subtle differences in brain morphometric features present in adolescence were associated with the subsequent development of psychosis in what is believed to be the largest neuroimaging investigation to date involving people at clinical high risk (CHR).
Investigators found widespread lower cortical thickness (CT) in individuals at CHR, consistent with previously reported CT differences in individuals with an established psychotic disorder.
“This is the first study to definitively show that there are subtle, widespread structural brain differences in high-risk youth before they develop psychosis,” study investigator Maria Jalbrzikowski, PhD, assistant professor of psychiatry, University of Pittsburgh, said in an interview.
The findings also suggest that there are developmental periods during which certain brain abnormalities may be more apparent, “highlighting the need to consider developmental period when developing objective, biological risk factors for early intervention in psychosis,” Dr. Jalbrzikowski said.
The study was published online May 5 in JAMA Psychiatry.
‘Sobering’ results
The findings are based on pooled structural MRI scans from 3,169 individuals recruited at 31 international sites participating in the Enhancing Neuro Imaging Genetics Through Meta-Analysis (ENIGMA) Clinical High Risk for Psychosis Working Group.
Forty-five percent of the participants were female; the mean age was 21 years (range, 9.5 to 39.9 years).
The cohort included 1,792 individuals at CHR for psychosis and 1,377 healthy control persons. Using longitudinal clinical information, the researchers identified 253 individuals at CHR who went on to develop a psychotic disorder (CHR-PS+) and 1,234 at CHR who did not develop a psychotic disorder (CHR-PS-). For the remaining 305 individuals at CHR, follow-up data were unavailable.
Compared with healthy control persons, individuals at CHR had widespread lower CT measures but not lower surface area or subcortical volume. Lower CT measures in the fusiform, superior temporal, and paracentral regions were associated with conversion to psychosis.
The pattern of differences in cortical thickness in those in the CHR-PS+ group mirrored patterns seen in people with schizophrenia and in people with 22q11.2 microdeletion syndrome who developed a psychotic disorder.
The researchers note that although all individuals experience cortical thinning as they move into adulthood, in their study, cortical thinning was already present in participants aged 12 to 16 years who developed psychosis.
“We don’t yet know exactly what this means, but adolescence is a critical time in a child’s life – it’s a time of opportunity to take risks and explore, but also a period of vulnerability,” Dr. Jalbrzikowski said in a news release.
“We could be seeing the result of something that happened even earlier in brain development but only begins to influence behavior during this developmental stage,” she noted.
This analysis represents the largest-ever pooling of brain scans in children and young adults who were determined by psychiatric assessment to be at high risk of developing psychosis.
“These results were, in a sense, sobering. On the one hand, our dataset includes 600% more high-risk youth who developed psychosis than any existing study, allowing us to see statistically significant results in brain structure.”
“But the variance between whether or not a high-risk youth develops psychosis is so small that it would be impossible to see a difference at the individual level,” Dr. Jalbrzikowski said.
More work is needed in order for the findings to be translated into clinical care, she added.

FDA clears next-generation DBS system for movement disorders
The SenSight Directional Lead System for DBS therapy combines two recent advancements: sensing capability that allows real-time monitoring of brain signals to optimize settings for stimulation, and a “directional lead” that enables steering of electric current for more precise targeting of stimulation through the electrode.
“Until now, sensing capability and directional leads have not been available in the same DBS system, so we have had to choose one technology or the other, based on the predicted needs of each patient,” neurosurgeon Kelly Foote, MD, who performed the first implant of the SenSight System at University of Florida (UF) Health, said in a news release.
“Now, by coupling this new directional lead with a pulse generator capable of brain sensing, we are excited to be able to offer our patients the synergistic benefits of both technologies,” added Dr. Foote, codirector of the Norman Fixel Institute for Neurological Diseases at UF Health.
Dr. Foote said DBS systems capable of adjusting therapeutic stimulation in response to continuously recorded brain signals may lead to better DBS outcomes with fewer adverse effects.
“Adding a directional lead to such a system will improve our ability to localize abnormal signals and enable us to steer current more effectively to areas in the brain where it is most beneficial,” Dr. Foote said.
“We are excited to see the clinical benefits that the new SenSight directional lead system will provide to patients and physicians in the U.S.,” added Mike Daly, vice president and general manager of brain modulation at Medtronic.
Medtronic’s SenSight directional lead DBS system received CE Mark approval in Europe in March.

Schizophrenia meds a key contributor to cognitive impairment
Anticholinergic medication burden from antipsychotics, antidepressants, and other psychotropics has a cumulative effect of worsening cognitive function in patients with schizophrenia, new research indicates.
“The link between long-term use of anticholinergic medications and cognitive impairment is well-known and growing,” lead researcher Yash Joshi, MD, department of psychiatry, University of California, San Diego, said in an interview.
“While this association is relevant for everyone, it is particularly important for those living with schizophrenia, who often struggle with cognitive difficulties conferred by the illness itself,” said Dr. Joshi.
“Brain health in schizophrenia is a game of inches, and even small negative effects on cognitive functioning through anticholinergic medication burden may have large impacts on patients’ lives,” he added.
The study was published online May 14 in the American Journal of Psychiatry.
‘Striking’ results
Dr. Joshi and colleagues set out to comprehensively characterize how the cumulative anticholinergic burden from different classes of medications affect cognition in patients with schizophrenia.
They assessed medical records, including all prescribed medications, for 1,120 adults with a diagnosis of schizophrenia or schizoaffective disorder.
For each participant, prescribed medications were rated and summed using a modified anticholinergic cognitive burden (ACB) scale. Cognitive functioning was assessed by performance on domains of the Penn Computerized Neurocognitive Battery (PCNB).
The investigators found that 63% of participants had an ACB score of at least 3, which is “striking,” said Dr. Joshi, given that previous studies have shown that an ACB score of 3 in a healthy, older adult is associated with cognitive dysfunction and a 50% increased risk of developing dementia.
About one-quarter of participants had an ACB score of 6 or higher.
Yet, these high ACB scores are not hard to achieve in routine psychiatric care, the researchers note.
For example, a patient taking olanzapine daily to ease symptoms of psychosis would have an ACB score of 3; if hydroxyzine was added for anxiety or insomnia, the patient’s ACB score would rise to 6, they point out.
Lightening the load
Antipsychotics contributed more than half of the anticholinergic burden, while traditional anticholinergics, antidepressants, mood stabilizers, and benzodiazepines accounted for the remainder.
“It is easy even for well-meaning clinicians to inadvertently contribute to anticholinergic medication burden through routine and appropriate care. The unique finding here is that this burden comes from medications we don’t usually think of as typical anticholinergic agents,” senior author Gregory Light, PhD, with University of California, San Diego, said in a news release.
Anticholinergic medication burden was significantly associated with generalized impairments in cognitive functioning across all cognitive domains on the PCNB with comparable magnitude and after controlling for multiple proxies of functioning or disease severity.
Higher anticholinergic medication burden was associated with worse cognitive performance. The PCNB global cognitive averages for none, low, average, high, and very high anticholinergic burdens were, respectively (in z values), -0.51, -0.70, -0.85, -0.96, and -1.15.
The results suggest “total cumulative anticholinergic burden – rather than anticholinergic burden attributable to a specific antipsychotic or psychotropic medication class – is a key contributor to cognitive impairment in schizophrenia,” the researchers write.
“The results imply that if it is clinically safe and practical,” said Dr. Joshi.
“This may be accomplished by reducing overall polypharmacy or transitioning to equivalent medications with lower overall anticholinergic burden. While ‘traditional’ anticholinergic medications should always be scrutinized, all medications should be carefully evaluated to understand whether they contribute to cumulative anticholinergic medication burden,” he added.
Confirmatory findings
Commenting on the study for this news organization, Jessica Gannon, MD, assistant professor of psychiatry, University of Pittsburgh, said the author’s findings “aren’t surprising, but the work that they did was pretty comprehensive [and] further fleshed out some of our concerns about the impact of anticholinergics on cognitive function in patients with schizophrenia.”
“We certainly have to use some of these medications for patients, like antipsychotics that do have some anticholinergic burden associated with them. We don’t really have other options,” Dr. Gannon said.
“But certainly I think this calls us to be better stewards of medication in general. And when we prescribe for comorbid conditions, like depression and anxiety, we should be careful in our prescribing practices, try not to prescribe an anticholinergic medication, and, if they have been prescribed, to deprescribe them,” Dr. Gannon added.
The study was supported by grants from the National Institute of Mental Health; the Sidney R. Baer, Jr. Foundation; the Brain and Behavior Research Foundation; the VISN-22 Mental Illness Research, Education, and Clinical Center; and the Department of Veterans Affairs. Dr. Joshi and Dr. Gannon have reported no relevant financial relationships.

Deep brain stimulation is effective over the long haul
, new research indicates.
“Subthalamic nucleus stimulation is a well recognized treatment used for improving motor conditions and quality of life in people with Parkinson’s disease. Our study, for the first time, supports its efficacy in the very long term – 15 years after surgery and 25 years since the Parkinson’s disease diagnosis,” said Elena Moro, MD, PhD, Grenoble Alpes University, Grenoble, France.
“This information is relevant for physicians, patients, and their families when they need to decide about the surgical option to deal with Parkinson’s disease,” said Dr. Moro.
The study was published online June 2 in Neurology.
‘Don’t delay’
The findings are based on 51 patients with Parkinson’s disease who underwent treatment with bilateral STN-DBS for an average of 17 years (range, 15-24 years). Their average age at diagnosis was 40 years, and the average age at device implantation was 51 years.
The results demonstrate that STN-DBS continues to be effective for motor complications for longer than 15 years, reducing time spent with dyskinesia by 75% and time spent in the off-state by 58.7%. This is similar to the amount of improvement seen 1 year after surgery.
Doses of dopaminergic medications continued to be low at long-term follow-up; dosing was reduced by 50.6% compared with baseline.
There was also continued improvement in quality of life. Scores on the Parkinson’s Disease Quality of Life Questionnaire in the very long term were 13.8% better compared with baseline.
“Few and mostly manageable device-related adverse events were observed during the follow-up,” the authors reported in their article.
“Deep brain stimulation is already recommended when a patient’s conditions are not optimized by medical treatment. Patients with Parkinson’s disease without dementia and in good general health conditions are the best candidates for this surgery,” said Dr. Moro.
“Taking into account our results and the data available in the literature, DBS surgery should not be delayed when motor conditions and quality of life decline despite medical treatment, if patients meet the inclusion criteria,” she added.
A revolutionary treatment
The authors of an accompanying editorial say these results, which indicate better motor outcomes with less medication, “reinforce why STN-DBS has revolutionized treatment for advanced Parkinson’s disease.”
Kelvin Chou, MD, of the University of Michigan, Ann Arbor, and David Charles, MD, of Vanderbilt University, Nashville, Tenn., pointed out that longer disease duration is associated with an increase in the likelihood of cognitive impairment and psychosis, both of which are risk factors for nursing home placement, and they limit the ability to use dopaminergic medications.
Although many of the patients in this cohort experienced hallucinations and psychosis over the long follow-up period, “one can imagine that the number and severity would be higher without DBS therapy,” they wrote.
Key caveats, said Dr. Chou and Dr. Charles, are that the results are based on a highly selected cohort and that the patients were managed by experts in the field of movement disorders and DBS.
Additionally, the patients’ conditions were highly responsive to levodopa; there was a 75.3% baseline improvement in Unified Parkinson’s Disease Rating Scale motor scores from the off-state to the on-state. In general, most DBS centers consider a levodopa response of approximately 30% as an acceptable cutoff for moving forward with STN-DBS, they noted.
Despite these caveats and limitations, the results of the study are important with respect to counseling potential candidates for DBS, Dr. Chou and Dr. Charles said.
“A common question that patients have is, ‘How long do the benefits of DBS last?’ We can now reassure them that, at least for STN-DBS, improvement in motor complications lasts beyond 15 years and is often accompanied by improvement in quality of life. In other words, with STN-DBS, we can uncomplicate their motor complications for the long haul,” the editorial writers concluded.
The research had no targeted funding. Moro has received honoraria from Medtronic and Abbott for consulting and lecturing and an educational grant from Boston and Newronika. A complete list of disclosures is available with the original articles.

“Taking into account our results and the data available in the literature, DBS surgery should not be delayed when motor conditions and quality of life decline despite medical treatment, if patients meet the inclusion criteria,” she added.
A revolutionary treatment
The authors of an accompanying editorial say these results, which indicate better motor outcomes with less medication, “reinforce why STN-DBS has revolutionized treatment for advanced Parkinson’s disease.”
Kelvin Chou, MD, of the University of Michigan, Ann Arbor, and David Charles, MD, of Vanderbilt University, Nashville, Tenn., pointed out that longer disease duration is associated with an increase in the likelihood of cognitive impairment and psychosis, both of which are risk factors for nursing home placement, and they limit the ability to use dopaminergic medications.
Although many of the patients in this cohort experienced hallucinations and psychosis over the long follow-up period, “one can imagine that the number and severity would be higher without DBS therapy,” they wrote.
Key caveats, said Dr. Chou and Dr. Charles, are that the results are based on a highly selected cohort and that the patients were managed by experts in the field of movement disorders and DBS.
Additionally, the patients’ conditions were highly responsive to levodopa; there was a 75.3% baseline improvement in Unified Parkinson’s Disease Rating Scale motor scores from the off-state to the on-state. In general, most DBS centers consider a levodopa response of approximately 30% as an acceptable cutoff for moving forward with STN-DBS, they noted.
Despite these caveats and limitations, the results of the study are important with respect to counseling potential candidates for DBS, Dr. Chou and Dr. Charles said.
“A common question that patients have is, ‘How long do the benefits of DBS last?’ We can now reassure them that, at least for STN-DBS, improvement in motor complications lasts beyond 15 years and is often accompanied by improvement in quality of life. In other words, with STN-DBS, we can uncomplicate their motor complications for the long haul,” the editorial writers concluded.
The research had no targeted funding. Moro has received honoraria from Medtronic and Abbott for consulting and lecturing and an educational grant from Boston and Newronika. A complete list of disclosures is available with the original articles.

FDA expands rimegepant indication to include migraine prevention
Last year, rimegepant became the first calcitonin gene-related peptide (CGRP) receptor antagonist, available in a fast-acting orally disintegrating tablet, to be approved for the acute treatment of migraine with or without aura in adults.
Rimegepant is currently the only migraine medication approved to both treat acute migraine attacks and help prevent future migraine attacks.
The new indication allows for use of rimegepant for preventive treatment in adults with episodic migraine (more than 15 migraine days per month). Rimegepant may be used for up to 18 doses per month, which includes both acute and preventive therapy.
In a phase 2/3 study, oral rimegepant was superior to placebo in reducing monthly migraine days. About half of adults who took rimegepant experienced a 50% or greater reduction in the number of days of moderate to severe migraines per month.
The most common adverse effects of rimegepant therapy were nausea (2.7%) and stomach pain or indigestion (2.4%).
The FDA approval of rimegepant for the preventive treatment of migraine, along with its acute treatment indication, is “one of the most ground-breaking things to happen to migraine treatment in my 40 years of practicing headache medicine,” Peter J. Goadsby, MD, PhD, an investigator in the prevention study, said in a company news release.
“To have one medication patients can use to treat and prevent migraine will likely change the treatment paradigm for many of the millions of people who live with migraine,” said Dr. Goadsby, professor of neurology, University of California, Los Angeles and King’s College, London.

FDA fast tracks testing of schizophrenia drug for impaired cognition
The U.S. Food and Drug Administration has granted breakthrough therapy designation for Boehringer Ingelheim’s experimental agent for the treatment of cognitive impairment associated with schizophrenia (CIAS).
The drug, known as BI 425809, is a novel glycine transporter-1 inhibitor.
The company announced it will start the CONNEX phase 3 clinical trial program to assess the safety and efficacy of the drug for improving cognition for adults with schizophrenia.
The breakthrough therapy designation and the initiation of phase 3 testing are based on results from a phase 2 clinical trial published in The Lancet Psychiatry.
In the phase 2 trial, oral BI 425809, taken once daily, improved cognition after 12 weeks for patients with schizophrenia; doses of 10 mg and 25 mg showed the largest separation from placebo.
Impairment of cognitive function is a major burden for people with schizophrenia, and no pharmacologic treatments are currently approved for CIAS.
“Cognition is a fundamental aspect of everyday life, including problem solving, memory, and attention, which is why finding solutions for cognitive impairment is a key area of Boehringer Ingelheim mental health research,” Vikas Mohan Sharma, MS, with Boehringer Ingelheim, said in a news release.
“This breakthrough therapy designation further highlights the urgent need for novel treatments for people living with schizophrenia. By combining traditional treatment approaches with new and innovative technologies, we are developing targeted therapies that will help to ease the burden of mental health conditions and enable people living with these conditions to create more meaningful connections to their lives, loved ones, and society,” said Mr. Sharma.
The CONNEX clinical trial program is composed of three clinical trials – CONNEX-1, CONNEX-2, and CONNEX-3. All are phase 3 randomized, double-blind, placebo-controlled parallel group trials that will examine the efficacy and safety of BI 425809 taken once daily over a 26-week period for patients with schizophrenia.
The CONNEX trial program will use VeraSci’s Pathway electronic clinical outcome assessment platform, including VeraSci’s Virtual Reality Functional Capacity Assessment Tool (VRFCAT), which simulates key instrumental activities of daily living in a realistic interactive virtual environment, VeraSci explains in a news release announcing the partnership with Boehringer Ingelheim.
The VRFCAT is sensitive to functional capacity deficits and has been accepted into the FDA’s Clinical Outcome Assessment Qualification Program.
The CONNEX trials will also utilize speech biomarker technology from Aural Analytics, which will provide a “richer picture of trial participants’ cognition alongside more conventional clinical outcome measures,” Boehringer Ingelheim says.
“Several of the symptoms of schizophrenia are generated by cognitive and emotional processes that can be identified through disruptions in the outward flow of speech. Using innovative speech analytics may help to objectively assess the downstream consequences of these disruptions,” said Daniel Jones, Aural Analytics co-founder and CEO.

Heart benefits of DASH low-sodium diet ‘swift and direct’
New data show for the first time that combining the DASH (Dietary Approaches to Stop Hypertension) diet with sodium restriction decreases myocardial injury and cardiac strain, which are associated with subclinical cardiac damage and long-term cardiovascular risk.
“The benefits of healthy eating are swift and direct. High sodium is not just about taste, it causes heart strain,” Stephen Juraschek, MD, PhD, from Beth Israel Deaconess Medical Center, Boston, said in an interview.
“We should consciously follow a diet enriched with fruit and vegetables and low in sodium. Collectively, we should think about how foods are promoted in society and what is an acceptable amount of sodium for food supplies,” said Dr. Juraschek.
The findings, from a secondary analysis of the DASH-Sodium trial, were published the Journal of the American College of Cardiology.
Renewed focus on diet
“These data should spur a renewed focus on the critical need for widespread adoption of the DASH–low-sodium diet in the United States,” wrote the coauthors of a linked editorial.
“The challenge remains moving the DASH–low-sodium diet from the research world into the real world, where its significant health benefits can be fully realized,” they added.
The researchers evaluated the impact of the DASH diet and sodium restriction, individually and combined, on biomarkers of cardiac injury (high-sensitivity cardiac troponin I [hs-cTnI]), cardiac strain (N-terminal of the prohormone brain natriuretic peptide [NT-proBNP]), and inflammation (high-sensitivity C-reactive protein [hs-CRP]).
The DASH-Sodium trial was a controlled feeding study that enrolled 412 adults (mean age, 48 years; 56% women, 56% Black) with untreated systolic blood pressure between 120 and 159 mm Hg and diastolic blood pressure between 80 and 95 mm Hg. Mean baseline BP was 135/86 mm Hg.
Participants were randomly allocated to a typical American diet (control) or the heart-healthy DASH diet. Further, participants in both groups were assigned to each of three sodium intake levels: low (0.5 mg/kcal), medium (1.1 mg/kcal) or high (1.6 mg/kcal) for 30 days using a crossover design with washout periods in between.
Compared with the control diet, the DASH diet reduced hs-cTnI by 18% and hs-CRP by 13% with no impact on NT-proBNP.
In contrast, lowering sodium from high to low levels reduced NT-proBNP independent of diet by 19%, but did not alter hs-cTnI and mildly increased hs-CRP (9%).
Combining the DASH diet with sodium reduction lowered hs-cTnI by 20% and NT-proBNP by 23%, with no significant change in hs-CRP, compared with the high-sodium-control diet.
“Together, these findings imply that two distinct dietary strategies might improve two key pathways of subclinical cardiac damage: injury and strain,” Dr. Juraschek and colleagues wrote.
“These findings should strengthen public resolve for public policies that promote the DASH dietary pattern and lower sodium intake in the United States and globally,” they concluded.
“We need to talk about DASH more. Most adults in the U.S. have never heard of it,” Dr. Juraschek said in an interview.
“We need to promote nutrition literacy with regard to nutrition facts. Labeling is not very transparent and hard to understand. Many people don’t know where salt is hiding in their diet,” he added.
It will also be important to address disparities in access to healthy foods and food insecurity, Dr. Juraschek said.
“If we don’t address food costs and access, disparities in healthy eating will persist. Greater equity is key. We should also be mindful about populations dependent on others for meal preparation [children in schools or older adults on meal plans]. This might be regulated in ways that promote healthier eating population wide, but for these patients, they may not have autonomy to choose what they eat,” Dr. Juraschek said.
In their editorial, Neha J. Pagidipati, MD, and Laura P. Svetkey, MD, from Duke University and Duke Clinical Research Institute, Durham, N.C., said an important caveat is that the beneficial effects of diet and sodium restriction on cardiac injury and strain occurred in people without any clinical evidence of coronary artery disease or heart failure at baseline, “suggesting that this dietary combination can improve subclinical metrics of cardiac health.”
“Further, the impact on these markers was seen within weeks, indicating a relatively rapid impact on cardiac damage,” they added.
The measurement of cardiac biomarkers was supported by the National Institutes of Health/National Heart, Lung, and Blood Institute. The original DASH trial was supported by the NHLBI, the Office of Research on Minority Health, and the National Center for Research Resources. Dr. Juraschek and coauthors disclosed no relevant conflicts of interest. Dr. Pagidipati has received research support to the institution from Amgen, AstraZeneca, Boehringer Ingelheim, Eli Lilly, Novartis, Novo Nordisk, Regeneron, Sanofi, and Verily Life Sciences; and has received consultation fees from Boehringer Ingelheim, Eli Lilly, AstraZeneca, and Novo Nordisk.

New AHA/ASA guideline on secondary stroke prevention
When possible, diagnostic tests to determine the cause of a first stroke or transient ischemic attack (TIA) should be completed within 48 hours after symptom onset, the American Heart Association/American Stroke Association said in an updated clinical practice guideline.
“It is critically important to understand the best ways to prevent another stroke once someone has had a stroke or a TIA,” Dawn O. Kleindorfer, MD, chair of the guideline writing group, said in a news release.
“If we can pinpoint the cause of the first stroke or TIA, we can tailor strategies to prevent a second stroke,” said Dr. Kleindorfer, professor and chair, department of neurology, University of Michigan, Ann Arbor.
The updated guideline was published online May 24, 2021, in Stroke.
“The secondary prevention of stroke guideline is one of the ASA’s ‘flagship’ guidelines, last updated in 2014,” Dr. Kleindorfer said.
The update includes “a number of changes to the writing and formatting of this guideline to make it easier for professionals to understand and locate information more quickly, ultimately greatly improving patient care and preventing more strokes in our patients,” she noted.
Let pathogenic subtype guide prevention
For patients who have survived a stroke or TIA, management of vascular risk factors, particularly hypertension, diabetes, cholesterol/triglyceride levels, and smoking cessation, are key secondary prevention tactics, the guideline said.
Limiting salt intake and/or following a heart-healthy Mediterranean diet is also advised, as is engaging in at least moderate-intensity aerobic activity for at least 10 minutes four times a week or vigorous-intensity aerobic activity for at least 20 minutes twice a week.
“Approximately 80% of strokes can be prevented by controlling blood pressure, eating a healthy diet, engaging in regular physical activity, not smoking and maintaining a healthy weight,” Amytis Towfighi, MD, vice chair of the guideline writing group and director of neurologic services, Los Angeles County Department of Health Services, noted in the release.
For health care professionals, the guideline said specific recommendations for secondary prevention often depend on the ischemic stroke/TIA subtype. “Therefore, new in this guideline is a section describing recommendations for the diagnostic workup after ischemic stroke, to define ischemic stroke pathogenesis (when possible), and to identify targets for treatment to reduce the risk of recurrent ischemic stroke. Recommendations are now segregated by pathogenetic subtype,” the guideline stated.
Among the recommendations:
- Use multidisciplinary care teams to personalize care for patients and employ shared decision-making with the patient to develop care plans that incorporate a patient’s wishes, goals, and concerns.
- Screen for and initiate anticoagulant drug therapy to reduce recurrent events.
- Prescribe antithrombotic therapy, including antiplatelets or anticoagulants, in the absence of contraindications. The guideline noted that the combination of antiplatelets and anticoagulation is typically not recommended for preventing second strokes and that dual antiplatelet therapy (DAPT) – taking along with a second medication to prevent blood clotting – is recommended in the short term and only for specific patients: those with early arriving minor stroke and high-risk TIA or severe symptomatic stenosis.
- Consider or carotid artery stenting for select patients with narrowing of carotid arteries.
- Aggressive medical management of risk factors and short-term DAPT are preferred for patients with severe intracranial stenosis thought to be the cause of first stroke or TIA.
- In some patients, it’s reasonable to consider percutaneous closure of .
The guideline is accompanied by a systematic review and meta-analysis regarding the benefits and risks of dual antiplatelet versus single antiplatelet therapy for secondary stroke prevention. The authors conclude that DAPT may be appropriate for select patients.
“Additional research is needed to determine: the optimal timing of starting treatment relative to the clinical event; the optimal duration of DAPT to maximize the risk-benefit ratio; whether additional populations excluded from POINT and CHANCE [two of the trials examined], such as those with major stroke, may also benefit from early DAPT; and whether certain genetic profiles eliminate the benefit of early DAPT,” concluded the reviewers, led by Devin Brown, MD, University of Michigan.

When possible, diagnostic tests to determine the cause of a first stroke or transient ischemic attack (TIA) should be completed within 48 hours after symptom onset, the American Heart Association/American Stroke Association said in an updated clinical practice guideline.
“It is critically important to understand the best ways to prevent another stroke once someone has had a stroke or a TIA,” Dawn O. Kleindorfer, MD, chair of the guideline writing group, said in a news release.
“If we can pinpoint the cause of the first stroke or TIA, we can tailor strategies to prevent a second stroke,” said Dr. Kleindorfer, professor and chair, department of neurology, University of Michigan, Ann Arbor.
The updated guideline was published online May 24, 2021, in Stroke.
“The secondary prevention of stroke guideline is one of the ASA’s ‘flagship’ guidelines, last updated in 2014,” Dr. Kleindorfer said.
The update includes “a number of changes to the writing and formatting of this guideline to make it easier for professionals to understand and locate information more quickly, ultimately greatly improving patient care and preventing more strokes in our patients,” she noted.
Let pathogenic subtype guide prevention
For patients who have survived a stroke or TIA, management of vascular risk factors, particularly hypertension, diabetes, cholesterol/triglyceride levels, and smoking cessation, are key secondary prevention tactics, the guideline said.
Limiting salt intake and/or following a heart-healthy Mediterranean diet is also advised, as is engaging in at least moderate-intensity aerobic activity for at least 10 minutes four times a week or vigorous-intensity aerobic activity for at least 20 minutes twice a week.
“Approximately 80% of strokes can be prevented by controlling blood pressure, eating a healthy diet, engaging in regular physical activity, not smoking and maintaining a healthy weight,” Amytis Towfighi, MD, vice chair of the guideline writing group and director of neurologic services, Los Angeles County Department of Health Services, noted in the release.
For health care professionals, the guideline said specific recommendations for secondary prevention often depend on the ischemic stroke/TIA subtype. “Therefore, new in this guideline is a section describing recommendations for the diagnostic workup after ischemic stroke, to define ischemic stroke pathogenesis (when possible), and to identify targets for treatment to reduce the risk of recurrent ischemic stroke. Recommendations are now segregated by pathogenetic subtype,” the guideline stated.
Among the recommendations:
- Use multidisciplinary care teams to personalize care for patients and employ shared decision-making with the patient to develop care plans that incorporate a patient’s wishes, goals, and concerns.
- Screen for and initiate anticoagulant drug therapy to reduce recurrent events.
- Prescribe antithrombotic therapy, including antiplatelets or anticoagulants, in the absence of contraindications. The guideline noted that the combination of antiplatelets and anticoagulation is typically not recommended for preventing second strokes and that dual antiplatelet therapy (DAPT) – taking along with a second medication to prevent blood clotting – is recommended in the short term and only for specific patients: those with early arriving minor stroke and high-risk TIA or severe symptomatic stenosis.
- Consider or carotid artery stenting for select patients with narrowing of carotid arteries.
- Aggressive medical management of risk factors and short-term DAPT are preferred for patients with severe intracranial stenosis thought to be the cause of first stroke or TIA.
- In some patients, it’s reasonable to consider percutaneous closure of .
The guideline is accompanied by a systematic review and meta-analysis regarding the benefits and risks of dual antiplatelet versus single antiplatelet therapy for secondary stroke prevention. The authors conclude that DAPT may be appropriate for select patients.
“Additional research is needed to determine: the optimal timing of starting treatment relative to the clinical event; the optimal duration of DAPT to maximize the risk-benefit ratio; whether additional populations excluded from POINT and CHANCE [two of the trials examined], such as those with major stroke, may also benefit from early DAPT; and whether certain genetic profiles eliminate the benefit of early DAPT,” concluded the reviewers, led by Devin Brown, MD, University of Michigan.
