TOPLINE:

A genetic predisposition to sleep 5 or fewer hours per night is associated with a significantly higher risk for subsequent depression. However, a genetic propensity to depression is not associated with suboptimal sleep patterns later on, new research shows.

METHODOLOGY:

• The analysis included participants in the English Longitudinal Study of Ageing (ELSA), a prospective cohort study of a representative U.K. sample (mean age, 65 years) that is assessed biennially.
• Researchers collected data on sleep duration and depression through nursing home visits and computer-assisted personal interviews and used combined ELSA waves from 2004 to 2008, when collection of genetic data began.
• Using genome-wide association studies from the U.K. Biobank, the authors constructed polygenic scores (PGSs) to predict an individual’s genetic risk over an average of 8 years for a disease or outcome, overall sleep duration, short sleep (≤ 5 hours nightly), long sleep (≥ 9 hours of sleep nightly), and depression.
• The analysis included two analytic samples; one involved 6,521 persons to determine the role of baseline sleep on depression (assessed using the Center for Epidemiologic Studies Depression Scale) at follow-up, and the other involved 6,070 persons to determine the role of baseline depression on suboptimal sleep at follow-up.

TAKEAWAY:

• After adjustments, including for age and sex, a 1–standard deviation increase in PGS for short sleep was associated with an increase of 14% in odds of developing depression during the follow-up period (odds ratio, 1.14; P = .008).
• There was no significant association of the PGS for sleep duration (P = .053) or long sleep (P = .544) with the onset of depression.
• There were no significant associations between PGS for depression and future overall sleep duration, short sleep, and long sleep by the end of the follow-up, suggesting that different mechanisms underlie the relationship between depression and subsequent onset of suboptimal sleep in older adults.
• Several sensitivity analyses – including additional adjustment for socioeconomic, environmental, and behavioral factors – upheld the findings of the main analysis, highlighting the robustness of the results.

IN PRACTICE:

The study showed that common genetic markers for short sleep play an important role in the incidence of depression in older adults, the authors note, adding that the new findings “support a growing view that short-sleep is more salient to the experience of depression than long sleep” across the lifespan.

SOURCE:

The study was led by Odessa S. Hamilton, department of behavioral science and health, University College London. It was published online  in Translational Psychiatry.

LIMITATIONS:

There are probably intraindividual differences in sleep duration that were not assessed in the study. The depression scale used may be indicative of subclinical depression and not major depressive disorder. The phenotypic sensitivity analyses did not account for comorbidities or medications that can affect sleep duration and depression.

DISCLOSURES:

ELSA is funded by the National Institute on Aging and by a consortium of U.K. government departments coordinated by the National Institute for Health and Care Research. The authors report no relevant conflicts of interests.

TOPLINE:

Black psychiatric inpatients are 85% more likely to be restrained with a physical or mechanical hold or with medication than White patients, and often for longer periods, new research suggests.

METHODOLOGY:

• The study, part of a larger retrospective chart review of inpatient psychiatric electronic medical records (EMRs), included 29,739 adolescents (aged 12-17 years) and adults admitted because of severe and disruptive psychiatric illness or concerns about self-harm.
• A restraint event was defined as a physician-ordered physical or mechanical hold in which patients are unable to move their limbs, body, or head or are given medication to restrict their movement.
• Researchers used scores on the Dynamic Appraisal of Situational Aggression (DASA) at admission to assess risk for aggression among high-risk psychiatric inpatients (scores ranged from a low of 0 to a high of 7).
• From restraint event data extracted from the EMR, researchers investigated whether restraint frequency or duration was affected by “adultification,” a form of racial bias in which adolescents are perceived as being older than their actual age and are treated accordingly.

TAKEAWAY:

• Of the entire cohort, 1867 (6.3%) experienced a restraint event, and 27,872 (93.7%) did not.
• Compared with White patients, restraint was 85% more likely among Black patients (adjusted odds ratio, 1.85; P < .001) and 36% more likely among multiracial patients (aOR, 1.36; P = .006), which researchers suggest may reflect systemic racism within psychiatry and medicine, as well as an implicit or learned perception that people of color are more aggressive and dangerous.
• Lower DASA score at admission (P = .001), shorter length of stay (P < .001), adult age (P = .001), female sex (P = .042), and Black race, compared with White race (P = .001), were significantly associated with longer restraint duration, which may serve as a proxy for psychiatric symptom severity.
• Neither age group alone (adolescent or adult) nor the interaction of race and age group was significantly associated with experiencing a restraint event, suggesting no evidence of “adultification.”

IN PRACTICE:

It’s important to raise awareness about racial differences in restraint events in inpatient psychiatric settings, the authors write, adding that addressing overcrowding and investing in bias assessment and restraint education may reduce bias in the care of agitated patients and the use of restraints.

SOURCE:

The study was carried out by Sonali Singal, BS, Institute of Behavioral Science, Feinstein Institutes for Medical Research, Manhasset, N.Y., and colleagues. It was published online  in Psychiatric Services.

LIMITATIONS:

The variables analyzed in the study were limited by the retrospective chart review and by the available EMR data, which may have contained entry errors. Although the investigators used DASA scores to control for differences in aggression, they could not control for symptom severity. The study could not examine the impact of race on seclusion (involuntary confinement), a variable often examined in tandem with restraint, because there were too few such events. The analysis also did not control for substance use disorder, which can influence a patient’s behavior and be related to restraint use.

DISCLOSURES:

Ms. Singal reported no relevant financial relationships. The original article has disclosures of other authors.

TOPLINE:

The prevalence of elevated LDL cholesterol (LDL-C) has declined over the past 2 decades, but 1 in 17 Americans still have a level of 160-189 mg/dL, and 1 in 48 have a level of at least 190 mg/dL, new research shows. Among people with the higher LDL-C level, one in four are both unaware and untreated, the authors report.

METHODOLOGY:

• Using data on 23,667 adult participants in the National Health and Nutrition Examination Survey conducted from 1999 to 2020, researchers identified 1,851 (7.8%) with an LDL-C level of 160-189 mg/dL and 669 (2.8%) with an LDL-C level of at least 190 mg/dL.
• Individuals were classified as “unaware” if they had never had their LDL-C measured or had never been informed of having elevated LDL-C and as “untreated” if their medications didn’t include a statin, ezetimibe, a bile acid sequestrant, or a proprotein convertase subtilisin/kexin type 9 inhibitor.
• The authors compared the prevalence of “unaware” and “untreated” by age, sex, race and ethnicity, educational attainment, poverty index, and insurance status.

TAKEAWAY:

• During the study period, the age-adjusted prevalence of an LDL-C level of 160-189 mg/dL declined from 12.4% (95% confidence interval, 10.0%-15.3%), representing 21.5 million U.S. adults, to 6.1% (95% CI, 4.8%-7.6%), representing 14.0 million adults (P < .001).
• The age-adjusted prevalence of an LDL-C level of at least 190 mg/dL declined from 3.8% (95% CI, 2.8%-5.2%), representing 6.6 million adults, to 2.1% (95% CI, 1.4%-3.0%), representing 4.8 million adults (P = .001).
• Among those with an LDL-C level of 160-189 mg/dL, the proportion of who were unaware and untreated declined from 52.1% to 42.7%, and among those with an LDL-C level of at least 190 mg/dL, it declined from 40.8% to 26.8%.
• Being unaware and untreated was more common in younger adults, men, racial and ethnic minority groups, those with lower educational attainment, those with lower income, and those without health insurance.

IN PRACTICE:

The lack of awareness and treatment of high LDL-C uncovered by the study “may be due to difficulties accessing primary care, low rates of screening in primary care, lack of consensus on screening recommendations, insufficient emphasis on LDL-C as a quality measure, and hesitance to treat asymptomatic individuals,” the authors concluded.

SOURCE:

The research was led by Ahmed Sayed, MBBS, faculty of medicine, Ain Shams University, Cairo, Egypt. It was published online in JAMA Cardiology.

LIMITATIONS:

The analysis was limited by a small number of participants with LDL-C levels of at least 190 mg/dL, possible nonresponse bias, and dependency on participant recall of whether LDL-C was previously measured. The inclusion of pregnant women may have influenced LDL-C levels.

DISCLOSURES:

Dr. Sayed has no relevant conflict of interest. The disclosures of the other authors are listed in the original publication.

TOPLINE:

Atrial fibrillation (AF) is associated with a 45% increased risk of mild cognitive impairment (MCI), an outcome that’s linked to cardiovascular risk factors and multi-comorbidity, results of a new study suggest.

METHODOLOGY:

• From over 4.3 million people in the UK primary electronic health record (EHR) database, researchers identified 233,833 (5.4%) with AF (mean age, 74.2 years) and randomly selected one age- and sex-matched control person without AF for each AF case patient.
• The primary outcome was incidence of mild cognitive impairment (MCI).
• The authors adjusted for age, sex, year at study entry, socioeconomic status, smoking, and a number of comorbid conditions.
• During a median of 5.3 years of follow-up, there were 4,269 incident MCI cases among both AF and non-AF patients.

TAKEAWAY:

• Individuals with AF had a higher risk of MCI than that of those without AF (adjusted hazard ratio [aHR], 1.45; 95% confidence interval [CI], 1.35-1.56).
• Besides AF, older age (risk ratio [RR], 1.08) and history of depression (RR, 1.44) were associated with greater risk of MCI, as were female sex, greater socioeconomic deprivation, stroke, and multimorbidity, including, for example, diabetes, hypercholesterolemia, and peripheral artery disease (all P < .001).
• Individuals with AF who received oral anticoagulants or amiodarone were not at increased risk of MCI, as was the case for those treated with digoxin.
• Individuals with AF and MCI were at greater risk of dementia (aHR, 1.25; 95% CI, 1.09-1.42). Sex, smoking, chronic kidney disease, and multi-comorbidity were among factors linked to elevated dementia risk.

IN PRACTICE:

The findings emphasize the association of multi-comorbidity and cardiovascular risk factors with development of MCI and progression to dementia in AF patients, the authors wrote. They noted that the data suggest combining anticoagulation and symptom and comorbidity management may prevent cognitive deterioration.

SOURCE:

The study was conducted by Sheng-Chia Chung, PhD, Institute of Health informatics Research, University College London, and colleagues. It was published online Oct. 25, 2023, as a research letter in the Journal of the American College of Cardiology (JACC): Advances. 

LIMITATIONS:

The EHR dataset may have lacked granularity and detail, and some risk factors or comorbidities may not have been measured. While those with AF receiving digoxin or amiodarone treatment had no higher risk of MCI than their non-AF peers, the study’s observational design and very wide confidence intervals for these subgroups prevent making solid inferences about causality or a potential protective role of these drugs.

• Individuals with AF had a higher risk of MCI than that of those without AF (adjusted hazard ratio [aHR], 1.45; 95% confidence interval [CI], 1.35-1.56).
• Besides AF, older age (risk ratio [RR], 1.08) and history of depression (RR, 1.44) were associated with greater risk of MCI, as were female sex, greater socioeconomic deprivation, stroke, and multimorbidity, including, for example, diabetes, hypercholesterolemia, and peripheral artery disease (all P < .001).
• Individuals with AF who received oral anticoagulants or amiodarone were not at increased risk of MCI, as was the case for those treated with digoxin.
• Individuals with AF and MCI were at greater risk of dementia (aHR, 1.25; 95% CI, 1.09-1.42). Sex, smoking, chronic kidney disease, and multi-comorbidity were among factors linked to elevated dementia risk.

IN PRACTICE:

The findings emphasize the association of multi-comorbidity and cardiovascular risk factors with development of MCI and progression to dementia in AF patients, the authors wrote. They noted that the data suggest combining anticoagulation and symptom and comorbidity management may prevent cognitive deterioration.

LIMITATIONS:

The EHR dataset may have lacked granularity and detail, and some risk factors or comorbidities may not have been measured. While those with AF receiving digoxin or amiodarone treatment had no higher risk of MCI than their non-AF peers, the study’s observational design and very wide confidence intervals for these subgroups prevent making solid inferences about causality or a potential protective role of these drugs.

TOPLINE:

Atrial fibrillation (AF) is associated with a 45% increased risk of mild cognitive impairment (MCI), an outcome that’s linked to cardiovascular risk factors and multi-comorbidity, results of a new study suggest.

METHODOLOGY:

• From over 4.3 million people in the UK primary electronic health record (EHR) database, researchers identified 233,833 (5.4%) with AF (mean age, 74.2 years) and randomly selected one age- and sex-matched control person without AF for each AF case patient.
• The primary outcome was incidence of mild cognitive impairment (MCI).
• The authors adjusted for age, sex, year at study entry, socioeconomic status, smoking, and a number of comorbid conditions.
• During a median of 5.3 years of follow-up, there were 4,269 incident MCI cases among both AF and non-AF patients.

TAKEAWAY:

• Individuals with AF had a higher risk of MCI than that of those without AF (adjusted hazard ratio [aHR], 1.45; 95% confidence interval [CI], 1.35-1.56).
• Besides AF, older age (risk ratio [RR], 1.08) and history of depression (RR, 1.44) were associated with greater risk of MCI, as were female sex, greater socioeconomic deprivation, stroke, and multimorbidity, including, for example, diabetes, hypercholesterolemia, and peripheral artery disease (all P < .001).
• Individuals with AF who received oral anticoagulants or amiodarone were not at increased risk of MCI, as was the case for those treated with digoxin.
• Individuals with AF and MCI were at greater risk of dementia (aHR, 1.25; 95% CI, 1.09-1.42). Sex, smoking, chronic kidney disease, and multi-comorbidity were among factors linked to elevated dementia risk.

TOPLINE:

Childhood trauma increases the risk of developing a primary headache disorder in adulthood, with more early adverse experiences raising the risk even more, a new study found.

METHODOLOGY:

• The meta-analysis included 28 observational studies with 154,739 persons in 19 countries that assessed the relationship between at least one adverse childhood experience (ACE) and primary headache (including migraine, tension-type headache, cluster headache, and chronic/severe headache) at age 21 years or older.
• From each study, researchers extracted outcome point estimates and corresponding 95% confidence intervals, number of events in each group, and covariates included in the model. They subcategorized ACEs according to those involving threat (for example, physical, emotional, or sexual abuse) and deprivation (for example, neglect, household substance misuse).
• For the primary analysis, the researchers calculated the odds ratios and hazard ratios of headache among persons with at least one ACE, compared with those with no ACEs.
• They also tested an underlying biological theory that threat and deprivation ACEs may manifest differently in neurodevelopment, with distinct impacts on primary headaches.
•  

TAKEAWAY:

• The most commonly reported ACEs were physical abuse (77%), sexual abuse (73%), and exposure to family violence (38%).
• Compared with having experienced no ACEs, experiencing at least one was associated with primary headaches (pooled OR, 1.48; 95% confidence interval, 1.36-1.61).
• As the number of ACEs increased, the strength of the association with primary headaches increased in a dose-response relationship (P for trend < .0001).
• Both threat and deprivation were independently associated with primary headaches; the pooled main effect was consistent for threat (OR, 1.46; 95% CI, 1.32-1.60) and for deprivation (OR, 1.35; 95% CI, 1.23-1.49), suggesting possible distinct pathways of early adversity.
•  

IN PRACTICE:

Clinicians who treat primary headaches in adults “should routinely screen for ACEs, educate patients on the connection between ACEs and health, and provide referrals for treatment strategies,” the investigators write. Strategies such as trauma-informed or attachment-based therapy may help rewire parts of the brain that have been dysregulated, they add.

SOURCE:

The study was led by Claudia Sikorski, department of health research methods, evidence, and impact, McMaster University, Hamilton, Ont. It was published online in Neurology.

LIMITATIONS:

The findings reflect a conservative estimate of the true impact of ACEs on primary headaches, because ACEs are commonly underreported. The analysis could not statistically disentangle younger adults with developing brains (age 21-26 years) from older adults. Not all included studies adjusted for age and sex, which are known risk factors for headaches. The study did not explore the relationship between ACEs and primary headache disorders in childhood and adolescence. Owing to the inherent nature of studies investigating ACEs, causation cannot be inferred.

DISCLOSURES:

The authors report no targeted funding and no relevant conflicts of interest.

TOPLINE:

Higher triglyceride levels – a main energy source for the brain – are associated with lower risk for dementia that is not mediated by age, sex, or APOE epsilon-4 allele status, a large study of community-dwelling older adults suggests.

METHODOLOGY:

• The analysis included 18,294 participants, median age 75 years and median triglyceride level 106 mg/dL, from the Aspirin in Reducing Events in the Elderly (ASPREE) study, a placebo-controlled, randomized trial of daily low-dose aspirin in older people without dementia or history of cardiovascular disease (CVD) at recruitment.
• Researchers repeated their main analyses in a sub-cohort of 13,976 subjects with APOE epsilon-4 genetic data, and an external cohort of 68,200 participants, mean age 66.9 years and a median nonfasting triglyceride of 139 mg/dL, from the UK biobank, followed for a median of 12.5 years.
• The main outcome was incident dementia over 6.4 years and secondary outcomes included changes in composite cognitive function and domain-specific cognition.
• Researchers controlled for a number of potential confounders, including age, sex, race, smoking, alcohol consumption, education, family history of dementia, diabetes, hypertension, and statin use.

TAKEAWAY:

• Every doubling of baseline triglycerides was associated with an 18% lower risk of incident dementia across the entire study cohort (adjusted hazard ratio, 0.82) and in participants with genotypic data (aHR, 0.82) and a 17% lower risk in the external UK Biobank cohort (aHR, 0.83) (P ≤ .01 for all).
• In the entire cohort, the risk for dementia was 15% lower in those with triglyceride levels at 63-106 mg/dL (aHR, 0.85); 24% lower in those at 107-186 mg/dL (aHR, 0.76); and 36% lower for those with levels higher than 187 mg/dL (aHR, 0.64), compared with individuals with levels below 62 mg/dL (P for trend <.001).
• The direction and magnitude of the inverse association between triglycerides and dementia risk were not modified by age, sex, or risk factors related to triglycerides or dementia.
• In the entire study cohort, higher triglyceride levels were significantly associated with slower decline in global cognition (P = .02), composite cognition (P = .03), and a borderline significantly slower decline in episodic memory (P = .05).

IN PRACTICE:

“Triglyceride levels may serve as a useful predictor for dementia risk and cognitive decline in older populations,” the investigators write. Higher triglyceride levels may reflect better overall health and/or lifestyle behaviors that protect against dementia.

SOURCE:

The study was led by Zhen Zhou, of Monash University, Melbourne. It was published online in Neurology.

LIMITATIONS:

The study can’t establish a causal relationship between triglyceride levels and dementia or fully exclude reverse causality. As most ASPREE participants had normal to high-normal triglyceride levels, the results can’t be generalized to those with severe hypertriglyceridemia. The findings are unique to older people without CVD and may not be generalizable to other populations.

DISCLOSURES:

The study received support from the Royal Australian College of General Practitioners (RACGP)/HCF Research Foundation. Dr. Zhou reported receiving salary from the RACGP/HCF Research Foundation.

TOPLINE:

Close adherence to the Portfolio dietary pattern, including foods that have been shown to actively lower cholesterol (for example, plant proteins, nuts, viscous fiber, phytosterols, and plant monounsaturated fats) is associated with a 14% lower risk for total cardiovascular disease (CVD), coronary heart disease (CHD), and stroke, pooled results from three large observational studies suggest.

METHODOLOGY:

• The study included 73,924 women from the Nurses’ Health Study (NHS), 92,346 women from the Nurses’ Health Study II (NHSII), and 43,970 men from the Health Professionals Follow-Up Study (HPFS) without CVD at baseline who were followed biennially on lifestyle, medical history, and other health-related factors.
• From food-frequency questionnaires (FFQs) completed every 4 years, researchers categorized foods into the six components of the Portfolio diet:
• Plant protein such as legumes, beans, tofu, peas, and soymilk
• Nuts and seeds
• Fiber sources such as bran, oats, berries, and eggplant
• Phytosterols
• Monounsaturated fat (MUFA) sources such as olive oil and avocado
• High saturated fat and cholesterol sources such as whole-fat dairy and red and processed meats
• They scored each from 1 (least adherent) to 5 (most adherent), with a higher score indicating higher consumption.
• Researchers examined the association of this Portfolio Diet Score (PDS) with total CVD, CHD, and stroke, in the three cohorts, and associations with plasma levels of lipid and inflammatory biomarkers in a subpopulation of the cohorts.

TAKEAWAY:

• During up to 30 years of follow-up, there were 16,917 incident CVD cases, including 10,666 CHD cases and 6,473 strokes.
• In a pooled analysis of the three cohorts, the fully adjusted hazard ratio for total CVD comparing the highest with the lowest quintile of the PDS was 0.86 (95% confidence interval, 0.81-0.92; P for trend < .001).
• Also comparing extreme quintiles, the pooled HR for CHD was 0.86 (95% CI, 0.80-0.93; P for trend = .0001) and for stroke, it was 0.86 (95% CI, 0.78-0.95; P for trend = .0003).
• A higher PDS was also associated with a more favorable lipid profile and lower levels of inflammation.

IN PRACTICE:

“This study provides additional evidence to support the use of the plant-based Portfolio dietary pattern for reducing the risk of CVD,” which aligns with American Heart Association guidelines promoting consumption of whole grains, fruits and vegetables, plant-based proteins, minimally processed foods, and healthy unsaturated plant oils, the authors conclude.

SOURCE:

The study was conducted by Andrea J. Glenn, PhD, RD, department of nutrition, Harvard T.H. Chan School of Public Health, Boston, and colleagues. It was published online in the journal Circulation.

LIMITATIONS:

As the study was observational, residual confounding can’t be ruled out. Diet was self-reported, which may have resulted in measurement errors. Consumption of some recommended foods was low, even in the top quintiles, so the association with CVD risk may be underestimated. Information on a few key Portfolio diet foods, including barley and okra, was unavailable, potentially leading to underestimation of intake, which may also attenuate the findings.

DISCLOSURES:

The study was supported by the Diabetes Canada End Diabetes 100 Award. The NH and HPFS studies are supported by the National Institutes of Health.

• Monounsaturated fat (MUFA) sources such as olive oil and avocado
• High saturated fat and cholesterol sources such as whole-fat dairy and red and processed meats
• They scored each from 1 (least adherent) to 5 (most adherent), with a higher score indicating higher consumption.
• Researchers examined the association of this Portfolio Diet Score (PDS) with total CVD, CHD, and stroke, in the three cohorts, and associations with plasma levels of lipid and inflammatory biomarkers in a subpopulation of the cohorts.

TAKEAWAY:

• During up to 30 years of follow-up, there were 16,917 incident CVD cases, including 10,666 CHD cases and 6,473 strokes.
• In a pooled analysis of the three cohorts, the fully adjusted hazard ratio for total CVD comparing the highest with the lowest quintile of the PDS was 0.86 (95% confidence interval, 0.81-0.92; P for trend < .001).
• Also comparing extreme quintiles, the pooled HR for CHD was 0.86 (95% CI, 0.80-0.93; P for trend = .0001) and for stroke, it was 0.86 (95% CI, 0.78-0.95; P for trend = .0003).
• A higher PDS was also associated with a more favorable lipid profile and lower levels of inflammation.

IN PRACTICE:

“This study provides additional evidence to support the use of the plant-based Portfolio dietary pattern for reducing the risk of CVD,” which aligns with American Heart Association guidelines promoting consumption of whole grains, fruits and vegetables, plant-based proteins, minimally processed foods, and healthy unsaturated plant oils, the authors conclude.

SOURCE:

The study was conducted by Andrea J. Glenn, PhD, RD, department of nutrition, Harvard T.H. Chan School of Public Health, Boston, and colleagues. It was published online in the journal Circulation.

LIMITATIONS:

As the study was observational, residual confounding can’t be ruled out. Diet was self-reported, which may have resulted in measurement errors. Consumption of some recommended foods was low, even in the top quintiles, so the association with CVD risk may be underestimated. Information on a few key Portfolio diet foods, including barley and okra, was unavailable, potentially leading to underestimation of intake, which may also attenuate the findings.

DISCLOSURES:

The study was supported by the Diabetes Canada End Diabetes 100 Award. The NH and HPFS studies are supported by the National Institutes of Health.

A device that stimulates the median nerve and a D1 receptor antagonist are among the promising new treatment approaches for patients with Tourette syndrome (TS), according to an overview of new therapies presented at the XXVI World Congress of Neurology.

One recent study by University of Nottingham researchers showed a wrist-worn stimulating device significantly reduces the frequency and severity of tics – repetitive movements or vocalizations that can occur several times a day.

“Wearable nerve stimulation holds great promise because it will be good across the age spectrum; adults can wear it to work, and children can go to school with it to help them concentrate on their schoolwork, and then they take it off at night,” Eileen Joyce, PhD, MB BChir, professor of neuropsychiatry at the Institute of Neurology, University College London, told this news organization.

Dr. Joyce, who was not part of the study, discussed this and other new advances in tic therapy at the meeting.

About 24% of children will suffer from tics at some point. The prevalence of Tourette syndrome among males is about four times that of females, Dr. Joyce told delegates. She added the typical age of onset is about 7 years with peak severity at about 12 years.

Predictors of tics persisting into adulthood include comorbid attention deficit hyperactivity disorder (ADHD), obsessive–compulsive disorder, and autism spectrum disorder, said Dr. Joyce, who also discussed the “highly heritable” nature of the syndrome and the numerous related genes identified to date.
 

Current and emerging treatments

Current treatments include psychological therapy, Botox for focal tics, and medications such as antipsychotics. Emerging therapies included deep brain stimulation and the new median nerve stimulation approach.

A study published  earlier this year included 135 patients with moderate to severe tic disorder who were randomly assigned to receive the investigational neuromodulation treatment, a sham treatment, or a wait-list treatment group.

The intervention involves rhythmic pulse trains of median nerve stimulation delivered via a device worn at the wrist. The device was programmed to deliver rhythmic (10 Hz) trains of low-intensity (1-19 mA) electrical stimulation to the median nerve at home once daily, 5 days a week for 4 weeks.

At 4 weeks, tic severity, as measured by the Yale Global Tic Severity Scale-Total Tic Severity Score (YGTSS-TTSS), was reduced by 7.1 points (35% reduction) in the active stimulation group compared to 2.13 points in the sham and 2.11 points in wait-list control groups.

The reduction for active stimulation was substantially larger, clinically meaningful (effect size, 0.5), and statistically significant (P = .02) compared to both the sham stimulation and wait-list control groups, which did not differ from one another.

Tic frequency (tics per minute or TPM) was reduced more in the active than sham stimulation groups (−15.6 TPM vs. −7.7 TPM; P < .03) and the reduction in tic frequency was clinically meaningful (>25% reduction; effect-size, 0.3).

When the active stimulator was turned off, the tics worsened, noted Dr. Joyce.

“The study showed that if you stimulate the median nerve at the wrist, you can train brain oscillations that are linked to the suppression of movement,” Dr. Joyce said. “So based on physiological knowledge, they have developed a median nerve stimulator to entrain cortical rhythms.”
 

Simple and exciting

The new device is “really exciting”, she added. “It’s not invasive and is quite simple to use and could help a lot of people with Tourette syndrome.”

Asked to comment, Alan Carson, MD, consultant neuropsychiatrist and honorary professor of neuropsychiatry, University of Edinburgh, who co-chaired the neuropsychiatry session featuring this presentation, called the device “promising.”

“Deep brain stimulation appears to be very effective but it’s a major procedure, so a simple wearable device seems highly desirable,” Dr. Carson said.

Dr. Joyce also discussed a study on the efficacy of cannabis (nabiximols; Sativex) as an intervention for tic management in males, those with severe tics, and those with comorbid ADHD.

And a new oral medication, ecopipam, a highly selective D1 receptor antagonist, is also raising hopes, said Dr. Joyce, with results from a randomized controlled trial  showing the drug significantly improved tics and had few adverse effects.

Dr. Joyce and Dr. Carson report no relevant financial relationships.

TOPLINE:

Tongxinluo, a traditional Chinese medicine made from extracts of multiple plants and insects, significantly reduced myocardial infarction (MI), stroke, and related events when used alongside guideline-directed treatments in patients with ST-segment elevation myocardial infarction (STEMI), results of a large trial suggest.

METHODOLOGY:

• The double-blind China Tongxinluo Study for Myocardial Protection in Patients With Acute Myocardial Infarction (CTS-AMI) included 3,777 adult patients, mean age 61 years, 76.9% men, with STEMI at 124 centers in China.
• Researchers randomly assigned patients to receive oral Tongxinluo using a loading dose of eight capsules (2.08 g) followed by a maintenance dose of four capsules (1.04 g) or oral placebo three times a day for 12 months.
• Doctors were instructed to also provide STEMI guideline-directed treatments, which include dual antiplatelet therapy and coronary reperfusion (percutaneous coronary intervention or thrombolysis).
• The primary endpoint was major adverse cardiac and cerebrovascular events (MACCEs) at 30 days, a composite of cardiac death, myocardial reinfarction, emergent coronary revascularization, and stroke.

TAKEAWAY:

• At 30 days, 3.4% in the Tongxinluo group and 5.2% in the placebo group had a MACCE (relative risk, 0.64; 95% confidence interval, 0.47-0.88; risk difference, –1.8%; 95% CI, –3.2% to –0.6%; P = .006).
• Individual components of MACCEs were also significantly lower in the Tongxinluo group, including 30-day cardiac death (3.0% vs. 4.2%; RR, 0.70; 95% CI, 0.50-0.99; P = .04) and myocardial reinfarction (0% vs. 0.5%; RR, 0.35; 95% CI, 0.13-0.99; P = .003), but there was no significant difference in 30-day stroke rate.
• At 1 year, the Tongxinluo group had a lower MACCE rate than did the placebo group (5.3% vs. 8.3%; hazard ratio, 0.64; 95% CI, 0.49-0.82; P = .001), an almost significant lower rate of all-cause death (5.1% vs. 6.6%; HR, 0.77; 95% CI, 0.59-1.01; P = .06), and lower rates of other outcomes.
• Rates of nonfatal serious adverse events were similar (2.2% in the Tongxinluo and 2.8% in the placebo groups; P = .25), but the Tongxinluo group had more adverse drug reactions (2.1% vs 1.1%; P = .02), which were mainly driven by symptoms in the digestive system such as stomach discomfort and nausea.

IN PRACTICE:

Unlike most traditional Chinese medicine research, the design of this study incorporated all key elements of randomized clinical trials, including placebo control and blinding in addition to randomization, so it “may serve as a model for future clinical trials to evaluate the safety and efficacy of traditional Chinese medicine,” the authors conclude.

In an accompanying editorial, Richard G. Bach, MD, cardiovascular division, Washington University School of Medicine, St. Louis, expressed skepticism about whether the benefits of Tongxinluo can be extrapolated to populations outside China that have distinct genetic backgrounds, lipid profiles, and diets. He also stressed that the active ingredients and mechanisms of action of Tongxinluo are unknown and noted reports suggesting that traditional Chinese medicines can contain undeclared material, heavy metals, and other adulterants associated with potentially toxic effects.

In an Editor’s Note, Gregory Curfman, MD, said in making a judgment about the validity of this research, “the editors were faced with the task of walking a fine line between skepticism and plausibility.” Though all patients should receive beta-blockers and an angiotensin-converting enzyme inhibitor or angiotensin II receptor blocker after STEMI, use of these drugs was suboptimal in these patients. Still, the benefits of Chinese medicine are plausible, said Dr. Curfman, noting research on the malaria drug artemisinin, which was isolated from a traditional Chinese medicine, was awarded the Nobel Prize.

SOURCE:

The research was led by Yuejin Yang, MD, PhD, department of cardiology, Fuwai Hospital, National Center for Cardiovascular Diseases, Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing, and colleagues. It was published online on Oct. 24 in JAMA. The results were previously reported at the American Heart Association Scientific Sessions 2022.

LIMITATIONS:

Despite the demonstrated clinical benefit of Tongxinluo, its active ingredients and the exact mechanisms of action have not been established. Use of guideline-directed medical therapy was suboptimal, with only 64% of patients prescribed beta-blockers and 51%-52% prescribed an ACE inhibitor or ARB during hospitalization, which may have affected the magnitude of the benefit of Tongxinluo. As study patients were all Chinese, the generalizability to other populations, especially in countries with higher adherence to guideline-directed medical therapy, is unknown.

DISCLOSURES:

The study received funding from the National Key Research and Development Program of China and a research grant from Shijiazhuang Yiling Pharmaceutical. Yuejin Yang reported receiving grants from Shijiazhuang Yiling Pharmaceutical and the National Key Research and Development Program of China; in addition, he has a patent related to the mechanisms of Tongxinluo in alleviating rat myocardial reperfusion injury and a patent related to the mechanisms of Tongxinluo on enhancing the protective effects of exosomes derived from mesenchymal stem cells in rat acute myocardial infarction.

TOPLINE:

New Canadian guidelines for the management of high-risk drinking and alcohol use disorder (AUD) include 15 recommendations on screening, diagnosis, withdrawal management, and ongoing treatment including psychosocial interventions, drug therapies, and community-based programs.

METHODOLOGY:

• The Canadian Research Initiative in Substance Misuse convened a 36-member committee of clinicians, researchers, people with personal experience of alcohol use, and Indigenous or Métis individuals to develop the guidelines, using the Appraisal of Guidelines for Research and Evaluation Instrument.
• Risk assessment was based on Alcohol Use Disorders Identification Test-Consumption scores.
• The definition of AUD was based on patients experiencing “clinically significant impairment or distress” from their alcohol use, with severity being mild, moderate, or severe.

TAKEAWAY:

• All adult and youth patients at moderate or high risk for AUD should be screened annually for alcohol use, and those screening positive should receive a diagnostic interview for AUD and an individualized treatment plan.
• Assessment of severe alcohol withdrawal complications should include clinical parameters such as past seizures or delirium tremens and the Prediction of Alcohol Withdrawal Severity Scale, with treatment including nonbenzodiazepine medications for low-risk patients and a short-term benzodiazepine prescription for high-risk patients, ideally in an inpatient setting.
• All patients with AUD should be referred for psychosocial treatment, and those with moderate to severe AUD should be offered naltrexone, acamprosate, topiramate, or gabapentin, depending on contraindications and effectiveness.
• Antipsychotics or SSRI antidepressants have little benefit and may worsen outcomes and should not be prescribed for AUD.

IN PRACTICE:

The authors noted that more than half of people aged 15 years or older in Canada drink more than the recommended amount, and about 18% meet the definition for AUD. “The aim of this guideline is to support primary care providers and services to offer more effective treatments routinely to patients with AUD as the standard of practice, with resulting improvements in health as well as potential for considerable cost savings in health and social systems,” the investigators write. They also note that policy makers can substantially improve standards of care by promoting adoption of the guideline and its recommendations.

LIMITATIONS:

The guideline was published more than 3 years after the initial literature search in September 2020 and did not include comprehensive guidance for AUD with co-occurring substance use disorders or with severe mental health conditions. Certain groups, including immigrant and refugee populations, were not represented.

DISCLOSURES:

Development of the guideline received support from Health Canada’s Substance Use and Addictions Program, Canadian Institutes of Health Research, and BC Centre on Substance Use. No committee members disclosed direct monetary or nonmonetary support from alcohol or pharmaceutical industry sources within the past 5 years, or that their clinical revenue would be influenced by the guideline recommendations.

TOPLINE:

New Canadian guidelines for the management of high-risk drinking and alcohol use disorder (AUD) include 15 recommendations on screening, diagnosis, withdrawal management, and ongoing treatment including psychosocial interventions, drug therapies, and community-based programs.

METHODOLOGY:

• The Canadian Research Initiative in Substance Misuse convened a 36-member committee of clinicians, researchers, people with personal experience of alcohol use, and Indigenous or Métis individuals to develop the guidelines, using the Appraisal of Guidelines for Research and Evaluation Instrument.
• Risk assessment was based on Alcohol Use Disorders Identification Test-Consumption scores.
• The definition of AUD was based on patients experiencing “clinically significant impairment or distress” from their alcohol use, with severity being mild, moderate, or severe.

TAKEAWAY:

• All adult and youth patients at moderate or high risk for AUD should be screened annually for alcohol use, and those screening positive should receive a diagnostic interview for AUD and an individualized treatment plan.
• Assessment of severe alcohol withdrawal complications should include clinical parameters such as past seizures or delirium tremens and the Prediction of Alcohol Withdrawal Severity Scale, with treatment including nonbenzodiazepine medications for low-risk patients and a short-term benzodiazepine prescription for high-risk patients, ideally in an inpatient setting.
