TOPLINE:

Women who use cocaine, cannabis, or other substances during pregnancy have increased risks of acute cardiovascular (CV) events while in the hospital for delivery, including more than double the risk of maternal mortality, a new study shows.

METHODOLOGY:

• Using the National Inpatient Sample database to identify hospital deliveries between 2004 and 2018 and diagnostic codes to identify maternal substance use, researchers compared 955,531 pregnancies with accompanying substance use – the most common substances being cannabis and opioids, followed by stimulants – to over 60 million pregnancies in which there was no substance use.
• The primary outcome was any CV event, including acute myocardial infarction, stroke, arrhythmia, endocarditis, any acute cardiomyopathy or heart failure, or cardiac arrest; other outcomes included maternal mortality and major adverse cardiac events (MACE).

TAKEAWAY:

• Deliveries complicated by substance use increased from 1,126 per 100,000 deliveries in 2004 to 1,547 per 100,000 in 2018, peaking at 2,187 per 100,000 in 2014.
• After the researchers controlled for patient demographics and CVD risk factors, results showed that pregnant women who used any substance (cannabis, opioids, methamphetamine, alcohol, tobacco, or cocaine) were more likely to experience a CVD event (adjusted odds ratio [aOR], 1.61; 95% confidence interval [CI], 1.53-1.70; P < .001), MACE (aOR, 1.53; 95% CI, 1.46-1.61; P < .001), or maternal mortality (aOR, 2.65; 95% CI, 2.15-3.25; P < .001) during hospitalization for delivery.
• Those using amphetamine/methamphetamine had ninefold higher odds of cardiomyopathy or heart failure and more than sevenfold higher odds of cardiac arrest.

IN PRACTICE:

“For the wellbeing of pregnant women and their children, substance use needs to be considered an independent risk factor for CV events in pregnancy,” the authors wrote. They called for prenatal assessments by a multidisciplinary cardio-obstetrics team to try to decrease cardiac complications.

In an accompanying editorial by Abha Khandelwal, MD, department of medicine, Stanford (Calif.) University, and others, the authors said the findings “highlight the critical support required during pregnancy and postpartum” for substance users, which should include comprehensive medical care and social services as well as access to addiction medicine and treatment of co-occurring mental health disorders.

SOURCE:

The study was carried out by Kari Evans, MD, division of maternal fetal medicine, department of obstetrics and gynecology, University of Arizona, Phoenix. It was published online in the Journal of the American College of Cardiology: Advances.

LIMITATIONS:

Use of administrative databases may have resulted in underreporting of diagnoses. The researchers could not assess the association of dose, duration, method, or timing of use for any substance with CV events. They also could not examine the effect of vaping on maternal CV events or differentiate hospitalizations for delivery that were complicated by CV events from hospitalizations for CV events that prompted delivery. The data did not reflect the postpartum period, during which a high rate of adverse CV events occurs.

DISCLOSURES:

The authors and editorial writers have no relevant conflicts of interest.

TOPLINE:

A new study confirms the safety and efficacy of the psychedelic MDMA in ethnically and racially diverse populations with moderate to severe posttraumatic stress disorder.

METHODOLOGY:

Trauma-focused psychotherapies are the gold standard treatment for PTSD, which affects about 5% of Americans each year. However, many patients have persistent symptoms, and up to 47% don’t respond to the SSRIs sertraline and paroxetine, which are approved for PTSD by the Food and Drug Administration.

Mounting evidence suggests 3,4-methylenedioxymethamphetamine-assisted therapy (MDMA-AT), which promotes monoamine reuptake inhibition and release, simultaneously inducing prosocial feelings and softening responses to emotionally challenging and fearful stimuli, could be an alternative treatment for PTSD, possibly enhancing the benefits of psychotherapy.

A phase 3 study (MAPP1) showed MDMA-AT was generally well-tolerated and met the primary and secondary endpoints of reduced PTSD symptom severity and decreased functional impairment.

This new confirmatory phase 3 study (MAPP2) included 104 patients with PTSD who were randomized to MDMA-AT or placebo with therapy. Participants were a mean age of about 39 years, 71.2% were assigned female sex at birth, 33.7% identified as non-White, and 26.9% identified as Hispanic/Latino.

The mean Clinician-Administered PTSD Scale for DSM-5 (CAPS-5) score at baseline was 39.0 and was similar between groups. Overall, 26.9% and 73.1% of patients had moderate or severe PTSD, respectively.
 

TAKEAWAY:

Among the 94 participants who completed the study, the least-squares mean change in CAPS-5 total score at 18 weeks was −23.7 (95% confidence interval, −26.9 to −20.4) for MDMA-AT versus −14.8 (95% CI, −18.3 to −11.3) for placebo with therapy (treatment difference: −8.9; 95% CI, −13.7 to −4.1; P < .001).

MDMA-AT significantly mitigated the secondary outcome of clinician-rated functional impairment, as measured by a reduction in the Sheehan Disability Scale score.

About 86.5% of participants treated with MDMA-AT achieved a clinically meaningful benefit, and 71.2% no longer met criteria for PTSD by study end.

Treatment-emergent adverse events were mostly transient and mild or moderate in severity. Although suicidal ideation was reported in both groups, MDMA did not appear to increase the risk, and there were no reports of problematic MDMA abuse or dependence.
 

IN PRACTICE:

“This confirmatory phase 3 trial showed consistent benefits of MDMA-AT in an ethnoracially diverse group of individuals with long-standing moderate to severe PTSD and numerous comorbidities,” write the authors, noting the dropout rate was low and treatment was generally well tolerated.

SOURCE:

The study was conducted by Jennifer M. Mitchell, PhD, department of neurology and department of psychiatry and behavioral sciences, University of California, San Francisco, and colleagues. It was published online in Nature Medicine.

LIMITATIONS:

The study excluded participants with high suicide risk, comorbid personality disorders, and underlying cardiovascular disease. Effect sizes for MDMA-AT were similar to MAPP1 and, although higher than those observed in SSRI studies, the superiority of MDMA-AT over SSRIs cannot be assumed without a direct comparison.

DISCLOSURES:

The study was funded by the Multidisciplinary Association for Psychedelic Studies, with support from the Steven and Alexandra Cohen Foundation, and organized by the MAPS Public Benefit Corporation. Dr. Mitchell has reported receiving research support from MAPS; grants/contracts from the Veterans Administration and FDA; royalties/licenses from the University of California, Los Angeles; and payment/honoraria from Stanford University and Johns Hopkins. She has been a reviewer for the National Institute on Drug Abuse Clinical Trials Network, a member of the Research Advisory Panel for the California Department of Justice, and a grant reviewer for the Australian National Health and Medical Research Council.

TOPLINE:

The drug mirabegron, used to treat overactive bladder disease, when added to standard treatment did not improve either left ventricular mass index or diastolic function over 12 months among patients with pre–heart failure (pre-HF) structural heart disease who were at risk of developing or worsening HF.

METHODOLOGY:

• Interventions for patients with asymptomatic pre-HF may be important in reducing the incidence of clinically overt HF, including HF with preserved ejection fraction (HFpEF).
• Mirabegron activates the cardiac beta-3 adrenergic receptor, which may offer an alternative activation of the cyclic guanosine monophosphate protein/kinase G (cGMP/PKG) pathway for patients at risk of or with mild HF and protect against worsening left ventricular hypertrophy (LVH) and/or diastolic dysfunction, but few clinical trials have evaluated the effect of mirabegron on cardiovascular outcomes.
• The phase 2b Beta3_LVH trial included 296 patients, some with and some without HF symptoms (mean age, 63 years), at 10 centers in Europe and the United Kingdom. All had an increased LV mass index (LVMI) (≥ 115 g/m² for men and ≥ 95 g/m² for women) or end-diastolic wall thickness of ≥ 13 mm in at least one wall segment.
• Patients, many of whom had risk factors, including hypertension, and were receiving cardiovascular therapies, were randomly assigned to receive mirabegron 50 mg/day or placebo and underwent various tests, including cardiac MRI, Doppler echocardiography, and urine and blood sampling for fasting glucose, insulin, hemoglobin A1c, serum lipids, and other measures.
• The two primary endpoints were change in left ventricular mass index (LVMI), expressed in grams per meters squared, and change in diastolic function, assessed as the ratio of peak early transmitral ventricular filling velocity to early diastolic tissue Doppler velocity (E/e´).

TAKEAWAY:

• Neither primary outcome reached statistical significance at 12 months; adjusted differences between groups included a 1.3g/m² increase in LVMI (95% confidence interval, −0.15 to 2.74; P = .08) and a −0.15 decrease in E/e´ (95% CI, −0.69 to 0.4; P = .60).
• There was no statistically significant effect of mirabegron, in comparison with placebo, on lipids, glycemic control, or insulin sensitivity.
• The effect of mirabegron remained neutral in exploratory subgroup analyses, including age (≤ 65 years or > 65 years at baseline), sex (men or women), body mass index (≤ 30 kg/m² or > 30 at baseline), presence of type 2 diabetes, atrial fibrillation, beta-blocker use, and geographic region.
• There were no deaths. There was a total of 428 adverse events (AEs), but there were no statistically significant between-group differences in the occurrence of these AEs.

IN PRACTICE:

While this study showed that mirabegron had a neutral effect on LV mass and diastolic function for patients with pre-HF or mild HF, the researchers suggest that longer-term effects of beta-3 adrenergic stimulation on myocardial remodeling and function “need to be tested in patients with established HFpEF, including with recent, more potent agonists.”

SOURCE:

The study was conducted by Jean-Luc Balligand, MD, Institut de Recherche Expérimentale et Clinique, Université Catholique de Louvain, Brussels, and colleagues. It was published online in JAMA Cardiology.

LIMITATIONS:

Inclusion of patients with mild HF and use of a single standard mirabegron dosage (50 mg/day) may have prevented detection of a treatment effect. More advanced techniques than measurements of E/e´, such as cardiac strain, may have been better for assessing early changes in diastolic function. Although missing data and dropouts were relatively infrequent and were compensated for in the study, these remain limitations.

DISCLOSURES:

The study was funded by European Commission Horizon 2020 Framework Programme. Dr. Balligand reported receiving grants from the European Commission during the conduct of the study, grants from Novartis and Daiichi Sankyo outside the submitted work, and consulting fees from Amgen, Novartis, and Daiichi Sankyo outside the submitted work; he also reported being a minor shareholder of Spinovit and serving as a board member for the Wallonia Health and Biotech Cluster, Biowin, and the AstraZeneca Foundation.

The study was conducted by Jean-Luc Balligand, MD, Institut de Recherche Expérimentale et Clinique, Université Catholique de Louvain, Brussels, and colleagues. It was published online in JAMA Cardiology.

LIMITATIONS:

Inclusion of patients with mild HF and use of a single standard mirabegron dosage (50 mg/day) may have prevented detection of a treatment effect. More advanced techniques than measurements of E/e´, such as cardiac strain, may have been better for assessing early changes in diastolic function. Although missing data and dropouts were relatively infrequent and were compensated for in the study, these remain limitations.

DISCLOSURES:

The study was funded by European Commission Horizon 2020 Framework Programme. Dr. Balligand reported receiving grants from the European Commission during the conduct of the study, grants from Novartis and Daiichi Sankyo outside the submitted work, and consulting fees from Amgen, Novartis, and Daiichi Sankyo outside the submitted work; he also reported being a minor shareholder of Spinovit and serving as a board member for the Wallonia Health and Biotech Cluster, Biowin, and the AstraZeneca Foundation.

TOPLINE:

Men exposed to either job-related stress or an imbalance between the effort they put in and the rewards they reap at work have a 50% increased risk for coronary heart disease (CHD), and those facing both stressors have double the risk compared with colleagues not suffering from these stressors, new research shows. Results in women were inconclusive, suggesting a more complex relationship of these factors, the researchers noted.

METHODOLOGY:

• Evidence suggests psychosocial stressors at work, from job strain related to level of demand and control in workload and decision-making responsibilities, and an effort-reward imbalance (ERI) in areas such as salary, promotion, and job stability, increase CHD risk, with the effect of both types of stressors together possibly being especially harmful.
• The study, which included 6,465 participants in the cardiovascular component of PROQ, a Canadian prospective cohort of white-collar workers initially free of cardiovascular disease, mean age 45 years, estimated that the separate and combined effect of job strain and ERI on CHD incidence.
• Researchers used the Job Content Questionnaire to assess psychological demands and job control; various measures; scales to determine job strain, reward, and effort at work; and the sum of both effort and reward to calculate the ERI ratio.
• They assessed CHD using medico-administrative databases and an algorithm validated by medical records.

TAKEAWAY:

• After a median follow-up of 18.7 years, there were 571 and 265 incident CHD cases among men and women, respectively.
• Men with either job strain or ERI had a 49% increased risk for CHD (hazard ratio [HR], 1.49; 95% confidence interval [CI], 1.07-2.09), an estimate comparable to that of several lifestyle risk factors for CHD.
• Male workers facing both job strain and ERI had a 103% increased risk for CHD (HR, 2.03; 95% CI, 1.38-2.97), which is comparable to the increased risk associated with obesity.
• Associations were robust to adjustments for demographic, socioeconomic, psychosocial, personality, stressful life events, and biomedical and lifestyle factors.
• Among women, results were inconclusive because the CIs were wide enough to encompass both protective and detrimental effects, suggesting more research is needed into the complex interplay of various stressors and women’s heart health.

IN PRACTICE:

“Integrative and interdisciplinary approaches should be used to tackle psychosocial stressors at work,” the authors wrote, adding this involves “going beyond traditional modifiable individual behaviors” and should include “population-based prevention strategies taking into consideration both the individual and their work environment.” 

SOURCE:

The study was conducted by Mathilde Lavigne-Robichaud, Population Health and Optimal Health Practices Research Unit, CHU de Québec-Laval University, Quebec City, Canada. It was published online in Circulation: Cardiovascular Quality and Outcomes. 

LIMITATIONS:

There was a risk for chance associations due to multiple testing. The exposure may have changed over the course of the study. Using medical databases for CHD event definition may have led to misclassification and underestimation of outcomes. The study population is limited to white-collar workers.

DISCLOSURES:

The study received funding from the Canadian Institute of Health Research. Lavigne-Robichaud was supported by a PhD grant from les Fonds de Recherche du Québec-Santé. See paper for disclosures of other authors.

TOPLINE:

In 2020, U.S. counties that were without psychiatric care or broadband coverage had significantly more drug overdose deaths and completed suicides, compared with other counties, new research shows.

METHODOLOGY:

• In the United States, there is a severe lack of psychiatrists and access to mental health care. In 2019, 21.3 million U.S. residents were without broadband access. These patients were forced either to use telephone consultation or to not use telehealth services at all, although use of telehealth during COVID-19 somewhat improved access to psychiatric care.
• For the study, researchers gathered sociodemographic and other county-level information from the American Community Survey. They also used data on the psychiatrist workforce from the Health Resources and Services Administration (HRSA) Area Health Resources Files.
• Information on broadband Internet coverage came from the Federal Communications Commission, and measures of mental health outcomes were from the Centers for Disease Control and Prevention.

TAKEAWAY:

• The study identified 596 counties (19% of all U.S. counties) that were without psychiatrists and in which there was inadequate broadband coverage. The population represented 10.5 million residents.
• Compared with other counties, those with lack of coverage were more likely to be rural (adjusted odds ratio, 3.05; 95% confidence interval, 2.41-3.84), to have higher unemployment (aOR, 1.12; 95% CI, 1.02-1.24), and to have higher uninsurance rates (aOR, 1.03; 95% CI, 1.00-1.06). In those counties, there were also fewer residents with a bachelor’s degree (aOR, 0.92; 95% CI, 0.90-0.94) and fewer Hispanics (aOR 0.98; 95% CI, 0.97-0.99), although those counties were not designated by the HRSA as having a psychiatrist shortage. That designation brings additional funding for the recruitment of clinicians.
• After adjustment for sociodemographic factors, counties without psychiatrists and broadband had significantly higher rates of adult depression, frequent mental distress, drug overdose mortality, and completed suicide, compared with other counties.
• Further analysis showed that the adjusted difference remained statistically significant for drug overdose mortality per 100,000 (9.2; 95% CI, 8.0-10.5, vs. 5.2; 95% CI, 4.9-5.6; P < .001) and completed suicide (10.6; 95% CI, 8.9-12.3, vs. 7.6; 95% CI, 7.0-8.2; P < .001), but not for the other two measures.

IN PRACTICE:

“Our finding suggests that lacking access to virtual and in-person psychiatric care continues to be a key factor associated with adverse outcomes,” the investigators write. They note that federal and state-level investments in broadband and the psychiatric workforce are needed.

SOURCE:

The study was conducted by Tarun Ramesh, BS, department of population medicine, Harvard Medical School and Harvard Pilgrim Health Care Institute, Boston, and colleagues. It was published online as a research letter in JAMA Network Open.

LIMITATIONS:

The investigators did not consider whether recent legislation, including the Consolidated Appropriations Act of 2021 and the American Rescue Plan, which expanded psychiatry residency slots and broadband infrastructure, reduces adverse outcomes, something the authors say future research should examine.

DISCLOSURES:

The study received support from the National Institutes of Health, including the National Institute on Minority Health and Health Disparities and the National Institute of Mental Health. The authors have disclosed no relevant financial relationships.

TOPLINE:

Prevalence of sexual dysfunction in schizophrenia patients remains high, with improved screening and treatment of depression possibly improving sexual health of these patients, results of a systematic review and meta-analysis show.

METHODOLOGY:

• Data on sexual dysfunction prevalence in people with schizophrenia should be updated because the only meta-analysis on this topic was published over 10 years ago, and factors that could explain the heterogeneity of sexual dysfunctions in schizophrenia also need reexamining.
• After carrying out a literature search for observational studies reporting prevalence of sexual dysfunction in outpatients receiving treatment for schizophrenia or schizoaffective disorder, researchers included 72 studies with 21,076 patients from 33 countries published between 1979 and 2021 in their review.
• They determined pooled estimates of sexual dysfunction prevalence in men and women and of each specific dysfunction.

TAKEAWAY:

• Pooled estimates for global prevalence were: 56.4% for sexual dysfunctions (95% confidence interval, 50.5-62.2), 40.6% for loss of libido (95% CI, 30.7-51.4), 28.0% for orgasm dysfunction (95% CI, 18.4-40.2), and 6.1% for genital pain (95% CI, 2.8-12.7), with study design, sociodemographic data, and other factors associated with the high heterogeneity of sexual dysfunctions.
• In men, estimates were: 55.7% for sexual dysfunction (95% CI, 48.1-63.1), 44.0% for erectile dysfunction (95% CI, 33.5-55.2), and 38.6% ejaculation dysfunction (95% CI, 26.8-51.8).
• In women, estimates were: 60.0% for sexual dysfunction (95% CI, 48.0-70.8), 25.1% for amenorrhea (95% CI, 17.3-35.0), and 7.7% for galactorrhea (95% CI, 3.7-15.3).
• Studies with the highest proportion of antidepressant prescriptions reported lower rates of sexual dysfunctions.

IN PRACTICE:

The review shows that sexual dysfunction is “extremely frequent” in schizophrenia and uncovers “important evidence” suggesting that better screening and treatment of depression “may be an effective strategy to improve sexual health in patients with schizophrenia,” write the authors.

SOURCE:

The study was carried out by Théo Korchia, MD, Assistance Publique-Hopitaux de Marseille, Aix-Marseille University, CEReSS: Health Service Research and Quality of Life Center, France, and colleagues. It was published online in JAMA Psychiatry.

LIMITATIONS:

Most factors known to increase sexual dysfunction, including hypertension, diabetes, obesity, smoking, and sleep disorders, were poorly explored in the included studies. Results may not be extrapolated to continents such as Africa and Polynesia because they were underrepresented in the review. The presence of publication bias in the meta-analysis can’t be entirely ruled out. Heterogeneity or methodological differences may have contributed to the observed results.

DISCLOSURES:

The authors have no relevant conflict of interest.

TOPLINE:

The disease-modifying treatment (DMT) delays conversion to clinical multiple sclerosis (MS) for patients with radiologically isolated syndrome (RIS) and has a reassuring long-term safety profile, new research shows.

METHODOLOGY:

Early use of DMTs is typically recommended for patients with established MS, but mounting evidence, including the ARISE trial, which assessed Tecfidera, suggests these agents benefit patients with RIS, the earliest detectable preclinical MS stage.

The new study, known as Teriflunomide in Radiologically Isolated Syndrome (TERIS), included 89 adult patients with RIS (mean age, 37.8 years) from centers in France, Switzerland, and Turkey. Participants were randomly assigned to receive placebo or teriflunomide 14 mg daily. Teriflunomide is an oral immunomodulator approved for treating relapsing remitting MS.

Investigators performed MRI at baseline and at weeks 48, 96, and 144 and at any time during the study if warranted.

Researchers adjusted for potential confounders, including sex, age at RIS diagnosis, MS family history, brain T2-weighted hyperintense lesion volume, and presence of Gd+/− lesions.

The primary outcome was time to a first acute or progressive neurologic event resulting from central nervous system demyelination, expressed as a rate of conversion to clinical MS.
 

TAKEAWAY:

Eighteen participants – nine in each group – discontinued the study, resulting in a dropout rate of 20%.

The risk of a first clinical event was significantly reduced in the teriflunomide arm (mean time to event, 128.2 weeks) with 8 clinical events (6 acute, 2 progressive) in comparison with the placebo arm (mean time to event, 109.6 weeks) with 20 clinical events (18 acute, 2 progressive) and an adjusted hazard ratio of 0.28 (95% CI, 0.11-0.71; P = .007).

All secondary MRI measures, including the cumulative number of new and/or newly enlarging T2 lesions and the cumulative number of Gd+ lesions, did not reach statistical significance, although these were numerically lower in the teriflunomide arm, possibly because participants with early events switched to the treatment arm.

The most common adverse events that occurred more often in patients treated with teriflunomide were gastrointestinal disorders (11.4%), dysmenorrhea (9.1%), benign respiratory infections (6.8%), general disorders/conditions (6.8%), and transient increase of transaminases (4.5%).
 

IN PRACTICE:

“These results suggest that for the first time, we may have an opportunity to better identify those at risk for a primary progressive clinical course at this preclinical stage and prevent or delay clinical progression from the onset, which is a clear unmet need in MS clinical practice,” wrote the authors.

SOURCE:

The study was carried out by Christine Lebrun-Frénay MD, PhD, head of the inflammatory neurological disorders clinical research unit and MS center at the University of Nice (France). It was published online in JAMA Neurology.

LIMITATIONS:

The investigators could not stratify at-risk subgroups according to risk factors for developing MS, mainly because of power issues. The study was prematurely discontinued by its financial sponsor (Sanofi), owing primarily to slow enrollment that resulted from national regulations on activating recruitment sites and the impact of the COVID-19 pandemic. Another challenge for the study was that some individuals with RIS had already been exposed to a DMT or hesitated to participate in a clinical trial. The financial sponsor, which provided the study drug and placebo tablets, terminated their availability, given the anticipated release of generic teriflunomide.

DISCLOSURES:

The study was supported by Sanofi, the University Hospital of Nice, University Cote d’Azur, and the Radiologically Isolated Syndrome Consortium. Lebrun-Frénay has no relevant conflicts of interest.

TOPLINE:

The disease-modifying treatment (DMT) delays conversion to clinical multiple sclerosis (MS) for patients with radiologically isolated syndrome (RIS) and has a reassuring long-term safety profile, new research shows.

METHODOLOGY:

Early use of DMTs is typically recommended for patients with established MS, but mounting evidence, including the ARISE trial, which assessed Tecfidera, suggests these agents benefit patients with RIS, the earliest detectable preclinical MS stage.

The new study, known as Teriflunomide in Radiologically Isolated Syndrome (TERIS), included 89 adult patients with RIS (mean age, 37.8 years) from centers in France, Switzerland, and Turkey. Participants were randomly assigned to receive placebo or teriflunomide 14 mg daily. Teriflunomide is an oral immunomodulator approved for treating relapsing remitting MS.

Investigators performed MRI at baseline and at weeks 48, 96, and 144 and at any time during the study if warranted.

Researchers adjusted for potential confounders, including sex, age at RIS diagnosis, MS family history, brain T2-weighted hyperintense lesion volume, and presence of Gd+/− lesions.

The primary outcome was time to a first acute or progressive neurologic event resulting from central nervous system demyelination, expressed as a rate of conversion to clinical MS.
 

TAKEAWAY:

Eighteen participants – nine in each group – discontinued the study, resulting in a dropout rate of 20%.

TOPLINE:

Globally, lead exposure is linked to more than 5.5 million adult cardiovascular deaths in 2019, as well as loss of 765 million intelligence quotient (IQ) points in children younger than 5 years, which cost U.S. $6 trillion in lost productivity, new research suggests.

METHODOLOGY:

• Global lead exposure has declined substantially since leaded gasoline was phased out, but several sources of lead remain, resulting in adverse health and economic effects, particularly in low- and middle-income countries (LMICs).
• Estimates of cardiovascular disease (CVD) deaths from lead exposure have been limited to effects of increased blood pressure, but studies show that lead exposure has cardiovascular impacts through mechanisms other than hypertension.
• Drawing from various sources and studies, researchers estimated global blood lead levels and the impact of lead exposure on CVD mortality in 2019 among adults aged 25 years or older, IQ loss in children younger than 5 years, and the related economic costs.

TAKEAWAY:

• Researchers estimated that there were 5,545,000 (95% confidence interval, 2,305,000-8,271,000) cardiovascular deaths in adults from lead exposure in 2019, with as many as 90.2% of these deaths in LMICs; however, this estimate may be incomplete because it does not include the effect of lead exposure on CVD mortality mediated through hypertension.
• The estimated global IQ loss in children younger than 5 years due to lead exposure was 765 million (95% CI, 443 million-1,098 million) IQ points in 2019, 95.3% of which occurred in LMICs.
• These estimates place lead exposure on a par with ambient particulate matter and household air pollution combined, and ahead of unsafe household drinking water, sanitation, and handwashing, as an environmental risk factor.
• The estimated global cost of lead exposure from CVD mortality and IQ loss combined is U.S. $6.0 trillion (range, $2.6 trillion-9.0 trillion) in 2019, equivalent to 6.9% of the 2019 global gross domestic product.

IN PRACTICE:

Given the magnitude of the estimated health effects of lead exposure, particularly in LMICs, “it is imperative that nationally representative periodic blood lead level measurements be institutionalized,” write the authors, adding that these measurements could be incorporated into existing household surveys.

STUDY DETAILS:

The study was conducted by Bjorn Larsen, PhD, environmental economist and consultant to the World Bank, and Ernesto Sánchez-Triana. It was published online in The Lancet Planetary Health.

LIMITATIONS:

• Global blood lead level estimates may be inaccurate, given that measurements are absent for many countries.
• Certain income projections and income losses are uncertain.
• Because the study does not capture the detrimental effects of lead exposure other than IQ loss and CVD mortality, the estimates of global costs are conservative.

DISCLOSURES:

The study received support from the Korea Green Growth Trust Fund and the World Bank’s Pollution Management and Environmental Health Program. The authors have no relevant conflicts of interest.

TOPLINE:

Eight psychosocial factors, grouped into two distinct clusters, are significantly associated with risk for atrial fibrillation in postmenopausal women, with insomnia and stressful life events (SLEs) being the most strongly associated with AFib, a large new study has found.

METHODOLOGY:

• In addition to traditional risk factors such as obesity, advanced age, ethnicity, smoking, alcohol, hypertension, diabetes, coronary artery disease, heart failure, and emotional and psychological distress may also affect AFib.
• The study included 83,736 postmenopausal women in the Women’s Health Initiative (mean age, 63.9 years; 88.1% White) who did not have AFib at baseline.
• From questionnaires, researchers collected information on psychosocial stressors and used hierarchical cluster analysis to identify patterns of psychosocial predictors.
• They separated these clusters into quartiles, identified associations between psychosocial exposure variables, and adjusted for traditional risk factors.
• Over an average follow-up of 10.5 years, 23,954 participants (28.6%) developed incident AFib.
•  

TAKEAWAY:

• The analysis generated two clusters of distinct psychosocial variables that were significantly associated with AFib: the Stress Cluster, including SLEs, depressive symptoms, and insomnia; and the Strain Cluster, including three personality traits: optimism, cynical hostility, and emotional expressiveness; and two social measures: social support, and social strain.
• Those in the highest quartiles of both the Stress Cluster and the Strain Cluster had greater rates of AFib, compared with those in the lowest quartiles.
• In a final model, the association between SLEs (hazard ratio, 1.02; 95% confidence interval, 1.01-1.04) and insomnia (HR, 1.04; 95% CI, 1.03-1.06) were most strongly linked to increased incidence of AFib, and a sensitivity analysis using snoring as a surrogate marker for sleep apnea didn’t change this outcome, supporting the independent effect of insomnia on AFib.
• In subgroup analyses, the Stress Cluster had a stronger association with AFib incidence in younger (50-69 years) versus older women (70-79 years), and in non-Hispanic White and Asian women versus Hispanic and non-Hispanic Black women.
•  

IN PRACTICE:

The results support the hypothesis that psychosocial predictors account for additional risk for AFib “above and beyond” traditional risk factors, the authors wrote. Identifying and addressing sex-specific, modifiable risk factors, including insomnia, “may help reduce the burden of AF[ib] in aging women.”

SOURCE:

The study was conducted by Susan X. Zhao, MD, division of cardiology, department of medicine, Santa Clara Valley Medical Center, San Jose, Calif., and colleagues. It was published online in the Journal of the American Heart Association.

LIMITATIONS:

The psychometric questionnaires were administered only at study entry, but psychosocial variables may change over time. Data on sleep apnea and other sleep disorders, which may confound the relationship between insomnia and AFib, were not available, and although the study included a sensitivity analysis controlling for snoring, this is an imperfect surrogate for sleep apnea. Generalizability to other demographic, racial, and ethnic groups is limited.

TOPLINE

First-year medical residents training during COVID-19 were significantly less likely to have posttraumatic stress disorder and workplace trauma, compared with their counterparts who trained before the pandemic, and reported fewer work hours, higher workload satisfaction, and fewer medical errors, new research shows.

METHODOLOGY

• Studies have reported a high prevalence of PTSD symptoms among residents during the pandemic, but it’s unclear if this prevalence differs from prepandemic levels.
• Using the Intern Health Study, a longitudinal cohort study of 1st-year residents, researchers investigated differences in PTSD symptoms among those training before the pandemic (2018-2019) and during its first wave (March to June, 2020).
• The study included 1,957 first-year residents (48.2% female; mean age, 27.6 years) who completed a baseline survey 2 months before their residency start, and then quarterly surveys during their intern year, with the fourth quarterly survey including a screen for PTSD.
• Researchers assessed differences in nonresidency factors and residency-related factors before and during the pandemic and examined exposure to workplace trauma.

TAKEAWAY

• Residents training during the pandemic were significantly less likely than pre-pandemic residents to screen positive for PTSD (7.1% vs. 10.7%; odds ratio, 0.64; 95% confidence interval, 0.46-0.88; P = .01).
• They were also less likely to have workplace trauma exposure (50.9% vs. 56.6%; OR, 0.80; 95% CI, 0.66-0.95; P = .01).
• Residents training during the pandemic compared to prepandemic reported significantly lower weekly duty hours (score mean difference –3.1 hours; 95% CI, –4.1 to −2.0 hours), lower mean reports of medical errors (MD, −0.04; 95% CI, –0.06 to –0.01), and higher workload satisfaction (MD, 0.2; 95% CI, 0.2-0.3).
• However, after accounting for these residency-related factors, training during the pandemic was no longer associated with lower odds of presenting PTSD symptoms.

IN PRACTICE

While the findings show residents training during the first pandemic wave were less likely to have PTSD, future studies should further follow these residents’ PTSD symptoms and investigate whether interventions targeting residency-related factors could reduce their PTSD risk moving forward, the investigators note.

SOURCE

The study was carried out by Michelle K. Ptak, BA, department of psychology, University of Michigan, Ann Arbor, and colleagues. It was published online Aug. 22 in JAMA Network Open.

LIMITATIONS

The study used self-reports and included only the first pandemic wave, 1st-year residents, and prepandemic data for a single academic year. Survey participation decreased during the pandemic, and it’s possible there were unmeasured factors associated with PTSD risk.

DISCLOSURES

The study was supported by the National Institute of Mental Health and the National Institutes of Health. The authors report no relevant financial relationships.

• However, after accounting for these residency-related factors, training during the pandemic was no longer associated with lower odds of presenting PTSD symptoms.

IN PRACTICE

While the findings show residents training during the first pandemic wave were less likely to have PTSD, future studies should further follow these residents’ PTSD symptoms and investigate whether interventions targeting residency-related factors could reduce their PTSD risk moving forward, the investigators note.

TOPLINE

First-year medical residents training during COVID-19 were significantly less likely to have posttraumatic stress disorder and workplace trauma, compared with their counterparts who trained before the pandemic, and reported fewer work hours, higher workload satisfaction, and fewer medical errors, new research shows.

METHODOLOGY

• Studies have reported a high prevalence of PTSD symptoms among residents during the pandemic, but it’s unclear if this prevalence differs from prepandemic levels.
• Using the Intern Health Study, a longitudinal cohort study of 1st-year residents, researchers investigated differences in PTSD symptoms among those training before the pandemic (2018-2019) and during its first wave (March to June, 2020).
• The study included 1,957 first-year residents (48.2% female; mean age, 27.6 years) who completed a baseline survey 2 months before their residency start, and then quarterly surveys during their intern year, with the fourth quarterly survey including a screen for PTSD.
• Researchers assessed differences in nonresidency factors and residency-related factors before and during the pandemic and examined exposure to workplace trauma.

TAKEAWAY

• Residents training during the pandemic were significantly less likely than pre-pandemic residents to screen positive for PTSD (7.1% vs. 10.7%; odds ratio, 0.64; 95% confidence interval, 0.46-0.88; P = .01).
• They were also less likely to have workplace trauma exposure (50.9% vs. 56.6%; OR, 0.80; 95% CI, 0.66-0.95; P = .01).
• Residents training during the pandemic compared to prepandemic reported significantly lower weekly duty hours (score mean difference –3.1 hours; 95% CI, –4.1 to −2.0 hours), lower mean reports of medical errors (MD, −0.04; 95% CI, –0.06 to –0.01), and higher workload satisfaction (MD, 0.2; 95% CI, 0.2-0.3).
• However, after accounting for these residency-related factors, training during the pandemic was no longer associated with lower odds of presenting PTSD symptoms.
