Long COVID symptoms can persist for more than 1 year, study shows
Nearly half of people who are hospitalized with COVID-19 suffer at least one lingering symptom 1 year after discharge, according to the largest study yet to assess the dynamic recovery of a group of COVID-19 survivors 12 months after the illness.
The most common lingering symptoms are fatigue and muscle weakness. One-third continue to have shortness of breath.
Overall, at 12 months, COVID-19 survivors had more problems with mobility, pain or discomfort, and anxiety or depression, and had lower self-assessment scores of quality of life than matched COVID-free peers, the investigators report.
The study was published online Aug. 28 in The Lancet.
“While most had made a good recovery, health problems persisted in some patients, especially those who had been critically ill during their hospital stay,” Bin Cao, MD, from the National Center for Respiratory Medicine at the China-Japan Friendship Hospital and Capital Medical University, both in Beijing, said in a Lancet news release.
“Our findings suggest that recovery for some patients will take longer than 1 year, and this should be taken into account when planning delivery of health care services post pandemic,” Dr. Cao said.
“As the COVID-19 pandemic continues, the need to understand and respond to long COVID is increasingly pressing,” says a Lancet editorial.
“Symptoms such as persistent fatigue, breathlessness, brain fog, and depression could debilitate many millions of people globally. Long COVID is a modern medical challenge of the first order,” it reads.
Study details
Dr. Cao and colleagues studied 1,276 COVID-19 patients (median age 59; 53% men) discharged from a hospital in Wuhan, China, between Jan. 7 and May 29, 2020. The patients were assessed at 6 and 12 months from the date they first experienced COVID-19 symptoms.
Many symptoms resolved over time, regardless of the severity of illness. Yet 49% of patients still had at least one symptom 12 months after their acute illness, down from 68% at the 6-month mark, the authors report.
Fatigue and muscle weakness were the most commonly reported symptoms seen in 52% of patients at 6 months and 20% at 12 months. Compared with men, women were 1.4 times more likely to report fatigue or muscle weakness.
Patients treated with corticosteroids during the acute phase of COVID-19 were 1.5 times as likely to experience fatigue or muscle weakness after 12 months, compared with those who had not received corticosteroids.
Thirty percent of patients reported dyspnea at 12 months, slightly more than at 6 months (26%). Dyspnea was more common in the most severely ill patients needing a ventilator during their hospital stay (39%), compared with those who did not need oxygen treatment (25%).
At the 6-month check, 349 study participants underwent pulmonary function tests and 244 of those patients completed the same test at 12 months.
Spirometric and lung volume parameters of most of these patients were within normal limits at 12 months. But lung diffusion impairment was observed in about 20%-30% of patients who had been moderately ill with COVID-19 and as high as 54% in critically ill patients.
Compared with men, women were almost three times as likely to have lung diffusion impairment after 12 months.
Of 186 patients with abnormal lung CT scan at 6 months, 118 patients had a repeat CT scan at 12 months. The lung imaging abnormality gradually recovered during follow-up, yet 76% of the most critically ill patients still had ground glass opacity at 12 months.
Mental health hit
Among those patients who had been employed full- or part-time before catching COVID, the majority had returned to their original job (88%) and most had returned to their pre-COVID-19 level of work (76%) within 12 months.
Among those who did not return to their original work, 32% cited decreased physical function, 25% were unwilling to do their previous job, and 18% were unemployed.
As shown in multiple other studies, COVID-19 can take a toll on mental health. In this cohort, slightly more patients reported anxiety or depression at 12 months than at 6 months (23% vs. 26%), and the proportion was much greater than in matched community-dwelling adults without COVID-19 (5%).
Compared with men, women were twice as likely to report anxiety or depression.
“We do not yet fully understand why psychiatric symptoms are slightly more common at 1 year than at 6 months in COVID-19 survivors,” study author Xiaoying Gu, PhD, from the Institute of Clinical Medical Sciences, China-Japan Friendship Hospital, said in the news release.
“These could be caused by a biological process linked to the virus infection itself, or the body’s immune response to it. Or they could be linked to reduced social contact, loneliness, incomplete recovery of physical health, or loss of employment associated with illness. Large, long-term studies of COVID-19 survivors are needed so that we can better understand the long-term physical and mental health consequences of COVID-19,” Dr. Gu said.
The authors caution that the findings represent a group of patients from a single hospital in China and the cohort included only a small number of patients who had been admitted to intensive care (94 of 1,276; 7.4%).
The Lancet editorial urges the scientific and medical community to “collaborate to explore the mechanism and pathogenesis of long COVID, estimate the global and regional disease burdens, better delineate who is most at risk, understand how vaccines might affect the condition, and find effective treatments via randomized controlled trials.”
“At the same time, health care providers must acknowledge and validate the toll of the persistent symptoms of long COVID on patients, and health systems need to be prepared to meet individualized, patient-oriented goals, with an appropriately trained workforce involving physical, cognitive, social, and occupational elements,” the editorial states.
“Answering these research questions while providing compassionate and multidisciplinary care will require the full breadth of scientific and medical ingenuity. It is a challenge to which the whole health community must rise,” the editorialists conclude.
The study was funded by the Chinese Academy of Medical Sciences Innovation Fund for Medical Sciences, the National Natural Science Foundation of China, the National Key Research and Development Program of China, Major Projects of National Science and Technology on New Drug Creation and Development of Pulmonary Tuberculosis, the China Evergrande Group, the Jack Ma Foundation, Sino Biopharmaceutical, the Ping An Insurance (Group), and the New Sunshine Charity Foundation.

FDA OKs IV Briviact for seizures in kids as young as 1 month
All three brivaracetam formulations (tablets, oral solution, and IV) may now be used. The approval marks the first time that the IV formulation will be available for children, the company said in a news release.
The medication is already approved in the United States as monotherapy and adjunctive therapy in adults with epilepsy.
In an open-label follow-up pediatric study, an estimated 71.4% of patients aged 1 month to 17 years with partial-onset seizures remained on brivaracetam therapy at 1 year, and 64.3% did so at 2 years, the company reported.
“We often see children with seizures hospitalized, so it’s important to have a therapy like Briviact IV that can offer rapid administration in an effective dose when needed and does not require titration,” Raman Sankar, MD, PhD, distinguished professor and chief of pediatric neurology, University of California, Los Angeles, said in the release.
“The availability of the oral dose forms also allows continuity of treatment when these young patients are transitioning from hospital to home,” he added.
Safety profile
Dr. Sankar noted that with approval now of both the IV and oral formulations for partial-onset seizures in such young children, “we have a new option that helps meet a critical need in pediatric epilepsy.”
The most common adverse reactions with brivaracetam include somnolence and sedation, dizziness, fatigue, nausea, and vomiting. In the pediatric clinical trials, the safety profile for pediatric patients was similar to adults.
In the adult trials, psychiatric adverse reactions, including nonpsychotic and psychotic symptoms, were reported in approximately 13% of adults taking at least 50 mg/day of brivaracetam compared with 8% taking placebo.
Psychiatric adverse reactions were also observed in open-label pediatric trials and were generally similar to those observed in adults.
Patients should be advised to report these symptoms immediately to a health care professional, the company noted.

Children’s upper airways primed to combat SARS-CoV-2 infection
Epithelial and immune cells of the upper airways of children are preactivated and primed to detect SARS-CoV-2 infection, which may contribute to stronger early immune responses to SARS-CoV-2 infection than adults, new research suggests.
The findings may help to explain why children have a lower risk of developing severe COVID-19 illness or becoming infected with SARS-CoV-2 in the first place, the researchers say.
The study was published online Aug. 18 in Nature Biotechnology.
Primed for action
Children appear to be better able than adults to control SARS-CoV-2 infection, but, until now, the exact molecular mechanisms have been unclear.
A team of investigators from Germany did an in-depth analysis of nasal swab samples obtained from 24 children and 21 adults who tested positive for SARS-CoV-2, as well as a control group of 18 children and 23 adults who tested negative for SARS-CoV-2.
“We wanted to understand why viral defense appears to work so much better in children than in adults,” Irina Lehmann, PhD, head of the molecular epidemiology unit at the Berlin Institute of Health Charité – Universitätsmedizin Berlin, explained in a news release.
Single-cell sequencing showed that children had higher baseline levels of certain RNA-sensing receptors that are relevant to SARS-CoV-2 detection, such as MDA5 and RIG-I, in the epithelial and immune cells of their noses.
This differential expression led to stronger early immune responses to SARS-CoV-2 infection in children than in adults.
Children were also more likely than adults to have distinct immune cell subpopulations, including KLRC1+ cytotoxic T cells, involved in fighting infection, and memory CD8+ T cells, associated with the development of long-lasting immunity.
‘Clear evidence’
The study provides “clear evidence” that upper-airway immune cells of children are “primed for virus sensing, resulting in a stronger early innate antiviral response to SARS-CoV-2 infection than in adults,” the investigators say.
Primed virus sensing and a preactivated innate immune response in children leads to efficient early production of interferons (IFNs) in the infected airways, likely mediating substantial antiviral effects, they note.
Ultimately, this may lead to lower viral replication and faster clearance in children. In fact, several studies have already shown that children eliminate the virus more quickly than adults, consistent with the concept that they shut down viral replication earlier, the study team says.
Weighing in on the findings for this news organization, John Wherry, PhD, director of the Institute for Immunology at the University of Pennsylvania, Philadelphia, said this “interesting study highlights potential differences in innate immunity and possibly geographic immunity in the upper respiratory tract in children versus adults.”
“We know there are differences in innate immunity over a lifespan, but exactly how these differences might relate to viral infection remains unclear,” said Dr. Wherry, who was not involved in the study.
“Children, of course, often have more respiratory infections than adults [but] whether this is due to exposure [i.e., daycare, schools, etc.] or susceptibility [lack of accumulated adaptive immunity over a greater number of years of exposure] is unclear,” Dr. Wherry noted.
“These data may help reveal what kinds of innate immune responses in the upper respiratory tract might help restrain SARS-CoV-2 and [perhaps partially] explain why children typically have milder COVID-19 disease,” he added.
The study was supported by the Berlin Institute of Health COVID-19 research program and fightCOVID@DKFZ initiative, European Commission, German Federal Ministry for Education and Research (BMBF), and German Research Foundation. Dr. Lehmann and Dr. Wherry have reported no relevant financial relationships.

“Children, of course, often have more respiratory infections than adults [but] whether this is due to exposure [i.e., daycare, schools, etc.] or susceptibility [lack of accumulated adaptive immunity over a greater number of years of exposure] is unclear,” Dr. Wherry noted.
“These data may help reveal what kinds of innate immune responses in the upper respiratory tract might help restrain SARS-CoV-2 and [perhaps partially] explain why children typically have milder COVID-19 disease,” he added.
The study was supported by the Berlin Institute of Health COVID-19 research program and fightCOVID@DKFZ initiative, European Commission, German Federal Ministry for Education and Research (BMBF), and German Research Foundation. Dr. Lehmann and Dr. Wherry have reported no relevant financial relationships.

Human brain patterns may help build a better AI system
new research suggests. “This work opens new opportunities to discover how the network organization of the brain optimizes cognitive capacity,” wrote researchers from The Neuro (Montreal Neurological Institute–Hospital) and the Quebec Artificial Intelligence Institute.
Senior investigator Bratislav Misic, PhD, said the research has potential clinical application for studying diseases of the brain, which is something his team is actively working on. “For example, using MRI techniques, we can measure different patterns of atrophy in neurodegenerative diseases such as Alzheimer’s disease,” he said.
“We can use these disease patterns from real patients to artificially lesion these connectomes and to ask how a particular disease causes a particular pattern of symptoms and cognitive deficits,” he added.
The findings were published online in Nature Machine Intelligence.
Unique approach
Using brain imaging data, the investigators reconstructed a human brain connectivity pattern and applied it to an artificial neural network. After training, the artificial neural network successfully performed a working memory task more flexibly and efficiently than other “benchmark” AI systems.
The researchers noted that their approach is unique because previous work on brain connectivity, also known as connectomics, has focused on describing brain organization without regard to how it actually functions.
Traditional artificial neural network have arbitrary structures that do not reflect how real brain networks are organized. Integrating brain connectomics into the construction of artificial neural network can reveal how the wiring of the brain supports specific cognitive skills, the investigators wrote.
“Up until now, if you look at how neural networks are constructed, the architectures that are used are very ad hoc and very problem specific,” Dr. Misic said. “But the connectomics revolution that’s happened in neuroscience over the past 20 years or so has given us the ability to really measure and trace out connection patterns in a variety of organisms, including the human brain.”
He noted that the researchers took wiring patterns of the real human brain and implemented it as an artificial neural network. They then “trained that network to perform a very simple cognitive task, and when you compare it to other benchmark architectures, it actually does better.”
This shows that there is “something fundamentally different about how the human brain is wired up and that the design principles that we can see in the human brain could be used to potentially build better artificial networks,” Dr. Misic concluded.
Funding for the research was provided by the Canada First Research Excellence Fund, awarded to McGill University for the Healthy Brains, Healthy Lives initiative, and by the Natural Sciences and Engineering Research Council of Canada, Fonds de Recherche du Quebec – Santé, the Canadian Institute for Advanced Research, Canada Research Chairs, Fonds de Recherche du Quebec – Nature et Technologies, and the Centre UNIQUE (Union of Neuroscience and Artificial Intelligence). The investigators have reported no relevant financial relationships.

Novel mutation may be unrecognized cause of sudden infant death
A previously healthy infant who survived sudden cardiac arrest at home was later found to have a de novo likely pathogenic genetic mutation in the SOS1 gene, which might be an unrecognized cause of sudden infant death, report clinicians from Missouri.
SOS1 gene variants are associated with Noonan syndrome, a genetic disorder that affects the RAS/MAPK signaling pathway. However, on presentation, the infant had none of the usual structural cardiac findings typical of Noonan syndrome, such as valvular disease or hypertrophic cardiomyopathy.
“To date, this is the first case reported of a ventricular fibrillation arrest in a patient with a RASopathy-related variant prior to development of the typically associated structural cardiac phenotype and may represent a previously unrecognized etiology of sudden death during infancy,” write Christopher W. Follansbee, MD, and Lindsey Malloy-Walton, DO, from the Ward Family Heart Center, Children’s Mercy Kansas City, and the University of Missouri School of Medicine.
“Genetic testing in cases of unexplained aborted or sudden cardiac deaths, even in previously healthy children, can be valuable in establishing a diagnosis, determining the prognosis, and assessing risk to family members,” they add in a news release.
Dr. Follansbee and Dr. Malloy-Walton describe the case in a report published in the August issue of HeartRhythm Case Reports.
Case details
The case involved a 2-month-old girl who did not wake up as usual for her morning feeding. Her mother found her limp, pale, and having difficulty breathing.
When emergency medical services arrived, the infant had no pulse. Cardiopulmonary resuscitation was initiated and an external defibrillator revealed coarse ventricular fibrillation. An initial shock of 10 J was given with conversion to an atrial rhythm with aberrant ventricular conduction.
The infant developed increasing frequency of ectopy before degenerating to ventricular fibrillation. A second shock with 20 J was unsuccessful, but a third shock of 20 J successfully converted the rhythm to sinus with aberrant ventricular conduction and atrial ectopy with return of spontaneous circulation.
In the ICU, the infant displayed incessant, nonsustained ectopic atrial tachycardia, with rapid episodes of ectopic atrial tachycardia with ventricular rates up to 300 beats per minute in the setting of seizure activity, they report.
With intravenous lorazepam, seizure activity resolved and treatment with amiodarone boluses led to transient establishment of sinus rhythm.
The QTc was noted to be above 500 ms and Brugada positioning of leads was unrevealing, the authors note.
Transthoracic echocardiogram showed a structurally normal heart with normal valve morphology and a patent foramen ovale with left-to-right flow. The initial ejection fraction was 49%. There was no evidence of ventricular hypertrophy, dilation, or noncompaction.
The infant was started on an esmolol infusion titrated to 225 μg/kg per min with frequent, nonsustained breakthrough of ectopic atrial tachycardia. Over the next 24 hours, the QTc interval normalized with normal T-wave morphology.
A procainamide challenge was negative. Cardiac MRI revealed normalization of ventricular function.
The genetics team was called in and a standard three-generation family history was obtained. An older sibling, 2 years of age, had no known medical conditions. The child’s paternal grandfather had died of a presumed myocardial infarction in his 50s, but no autopsy had been performed.
There was no family history of congenital heart disease, arrhythmia, sudden death, cardiomyopathy, recurrent syncope, congenital deafness, seizure, miscarriage, or developmental delay. Electrocardiograms obtained on the parents were normal.
Genetic testing using a comprehensive arrhythmia and cardiomyopathy next-generation sequencing panel revealed a de novo likely pathogenetic variant of the SOS1 gene associated with Noonan syndrome.
Given the aborted sudden cardiac death, the patient underwent dual-chamber epicardial implantable cardioverter-defibrillator implantation prior to discharge.
Dr. Follansbee and Dr. Malloy-Walton say a limitation to the case report is the lack of definitive association of the SOS1 variant with the presentation.
However, knowing the infant has the SOS1 variant and a history of aborted sudden death will allow for “monitoring and early intervention on typical manifestations of Noonan syndrome as the patient grows,” they say.
This research had no specific funding. Dr. Follansbee and Dr. Malloy-Walton have disclosed no relevant conflicts of interest.

Two patients with metastatic lung cancer are disease-free for 1.5 years after TILs
Adoptive cell therapy using tumor-infiltrating lymphocytes (TILs) led to complete and long-lasting responses in 2 of 16 patients with metastatic non-small cell lung cancer (NSCLC) who fully underwent the therapy in a phase 1 study.
The results are “very impressive, with two complete responses that are ongoing 1.5 years later, so it’s durable, and that’s encouraging,” Fred Hirsch, MD, PhD, director of the Center of Excellence for Thoracic Oncology at Mount Sinai’s Tisch Cancer Institute, New York, told this news organization.
Dr. Hirsch, who wasn’t involved in the research, also noted that this study is in immunotherapy-resistant metastatic lung cancer – “a situation where we actually don’t know exactly how best to treat it today.”
The study was published online in Nature Medicine.
A form of immunotherapy, TILs have been studied extensively in melanoma, as reported by this news organization, but this is the first test of the TIL therapy in metastatic NSCLC.
The single-arm, open-label phase 1 trial involved 20 patients who had TILs collected, including 16 who eventually received TILs. Median age was 54 years; all patients had metastatic NSCLC and disease progression after nivolumab monotherapy.
TILs cultured from an individual patient’s tumor were expanded ex vivo from minced tumors cultured with interleukin-2 (IL-2). Via this method, “billions of activated T cells can be produced and infused back into a patient,” explain the authors.
The full treatment regimen comprised cyclophosphamide and fludarabine lymphodepletion, TIL infusion and IL-2, followed by maintenance nivolumab.
“We found that infusion of TILs in combination with lymphodepletion and IL-2 had manageable toxicity and mediated tumor regressions in several patients, including complete responses,” report Benjamin Creelan, MD, of the Moffitt Cancer Center & Research Institute, Tampa, and colleagues.
The endpoint of safety was met according to the prespecified criteria of a rate of severe toxicity of 17% or less.
Among 13 evaluable patients, three had confirmed responses and 11 had reduction in tumor burden. Two patients achieved complete responses that were ongoing 1.5 years following TIL treatment.
One durable complete response occurred in a PD-L1-negative never-smoker, who had a low tumor mutation burden and who was refractory to nivolumab.
“This may be particularly encouraging for the large subset of never-smoker patients, for whom immune-checkpoint inhibitors have historically had limited efficacy,” the investigators say.
This complete responder had “features where you wouldn’t expect to see a response for immunotherapy,” Dr. Hirsch told this news organization.
“Low tumor mutation burden, negative PDL-1, and never-smoker are three factors which indicate some kind of resistance to immunotherapy, and despite that, there was a complete response with this specific therapy. That is fascinating,” he said.
In exploratory analyses, T cells recognizing multiple types of cancer mutations were detected after TIL treatment and were enriched in patients who responded to treatment.
The researchers say these early data indicate that TILs can mediate effective responses in tumor subtypes that are not sensitive to traditional immune-checkpoint-targeted therapy.
“Therefore, therapy with TILs may extend the scope and impact of immunotherapy into wider populations,” they write.
‘Yeoman’s effort’ paving the way forward
Also weighing in on the study, Philip Greenberg, MD, professor and head of immunology, Fred Hutchinson Cancer Center, Seattle, said, “In some respects, it’s quite promising and in other respects, actually more limited than you would hope for.”
“I think it’s a great demonstration that there is activity here, and there’s a world of things that can be done to improve the activity and no doubt that will be done. After this trial, I’m sure we will see next-generation trials,” said Dr. Greenberg.
He said key issues going forward are how cells are selected and manufactured: “That’s going to be a critical piece for making it better.”
“There is now a world of data that says T cells that recognize mutations in cancers can be effective in solid tumors,” Dr. Greenberg said.
“Sustaining that response is still a huge obstacle for achieving the kinds of therapeutic benefits we’d like to be achieved. And having that response be broad enough, particularly in the setting where most of the mutations are just passenger mutations, not driver oncogenes, is going to require a way of generating a large polyspecific population of cells that can persist for a long time,” he further commented.
All in all, this study was a “yeoman’s effort” and the researchers “deserve a lot of credit for pushing it forward,” Dr. Greenberg said.
The study was supported in part by grants from Stand Up to Cancer Foundation, the Barbara Bauer Prelude to a Cure Foundation, Iovance Biotherapeutics, and a Young Investigator award from Adaptive Biotechnologies. Nivolumab was supplied by Bristol-Myers Squibb. Aldesleukin (IL-2) was supplied by Clinigen Group. A complete list of author disclosures is available with the original article.

“I think it’s a great demonstration that there is activity here, and there’s a world of things that can be done to improve the activity and no doubt that will be done. After this trial, I’m sure we will see next-generation trials,” said Dr. Greenberg.
He said key issues going forward are how cells are selected and manufactured: “That’s going to be a critical piece for making it better.”
“There is now a world of data that says T cells that recognize mutations in cancers can be effective in solid tumors,” Dr. Greenberg said.
“Sustaining that response is still a huge obstacle for achieving the kinds of therapeutic benefits we’d like to be achieved. And having that response be broad enough, particularly in the setting where most of the mutations are just passenger mutations, not driver oncogenes, is going to require a way of generating a large polyspecific population of cells that can persist for a long time,” he further commented.
All in all, this study was a “yeoman’s effort” and the researchers “deserve a lot of credit for pushing it forward,” Dr. Greenberg said.
The study was supported in part by grants from Stand Up to Cancer Foundation, the Barbara Bauer Prelude to a Cure Foundation, Iovance Biotherapeutics, and a Young Investigator award from Adaptive Biotechnologies. Nivolumab was supplied by Bristol-Myers Squibb. Aldesleukin (IL-2) was supplied by Clinigen Group. A complete list of author disclosures is available with the original article.

Mediterranean diet slows progression of atherosclerosis in CHD
For patients with coronary heart disease (CHD), following a Mediterranean diet is more effective in reducing progression of atherosclerosis than following a low-fat diet, according to new data from the CORDIOPREV randomized, controlled trial.
“The current study is, to our knowledge, the first to establish an effective dietary strategy for secondary cardiovascular prevention, reinforcing the fact that the Mediterranean diet rich in extra virgin olive oil (EVOO) could prevent the progression of atherosclerosis,” the study team said.
The data also show that patients with a higher atherosclerotic burden might benefit the most from the Mediterranean diet.
The study was published online Aug. 10, 2021, in Stroke.
Mediterranean or low fat?
“It is well established that lifestyle and dietary habits powerfully affect cardiovascular risk,” study investigator Elena M. Yubero-Serrano, PhD, with Reina Sofia University Hospital/University of Cordoba (Spain), told this news organization.
“The effectiveness of the Mediterranean diet in reducing cardiovascular risk has been seen in primary prevention. However, currently there is no consensus about a recommended dietary model for the secondary prevention of cardiovascular disease,” she said.
The Coronary Diet Intervention With Olive Oil and Cardiovascular Prevention (CORDIOPREV) study is an ongoing prospective study comparing the effects of two healthy diets for secondary prevention of cardiovascular disease (CVD) in 1002 patients.
The comparative effect of the diets in reducing CVD risk, assessed by quantification of intima-media thickness of the common carotid arteries (IMT-CC), is a key secondary endpoint of the study.
During the study, half of the patients follow a Mediterranean diet rich in EVOO, fruit and vegetables, whole grains, fish, and nuts. The other half follow a diet low in fat and rich in complex carbohydrates.
A total of 939 participants (459 in the low-fat diet group and 480 in the Mediterranean diet group) completed IMT-CC evaluation at baseline, and 809 (377 and 432, respectively) completed the IMT-CC evaluation at 5 years; 731 (335 and 396, respectively) did so at 7 years.
The Mediterranean diet significantly decreased IMT-CC both after 5 years (–0.027; P < .001) and after 7 years (–0.031 mm; P < .001), relative to baseline. In contrast, the low-fat diet did not exert any change on IMT-CC after 5 or 7 years, the researchers report.
The higher the IMT-CC at baseline, the greater the reduction in this parameter.
The Mediterranean diet also produced a greater decrease in IMT-CC and carotid plaque maximum height, compared with the low-fat diet throughout follow-up.
There were no between-group differences in carotid plaque numbers during follow-up.
“Our findings, in addition to reinforcing the clinical benefits of the Mediterranean diet, provide a beneficial dietary strategy as a clinical and therapeutic tool that could reduce the high cardiovascular recurrence in the context of secondary prevention,” Dr. Yubero-Serrano said in an interview.
Earlier data from CORDIOPREV showed that, after 1 year of eating a Mediterranean diet, compared with the low-fat diet, endothelial function was improved among patients with CHD, even those with type 2 diabetes, which was associated with a better balance of vascular homeostasis.
The Mediterranean diet may also modulate the lipid profile, particularly by increasing HDL cholesterol levels. The anti-inflammatory capacity of the Mediterranean diet could be another factor that contributes to reducing the progression of atherosclerosis, the researchers say.
Important study
Reached for comment, Alan Rozanski, MD, professor of medicine, Icahn School of Medicine at Mount Sinai and cardiologist at Mount Sinai Morningside, New York, said: “We know very well that lifestyle factors, diet, and exercise in particular are extremely important in promoting health, vitality, and decreasing risk for chronic diseases, including heart attack and stroke.
“But a lot of the studies depend on epidemiological work. Until now, we haven’t had important prospective studies evaluating different kinds of dietary approaches and how they affect carotid intimal thickening assessments that we can do by ultrasound. So having this kind of imaging study which shows that diet can halt progression of atherosclerosis is important,” said Dr. Rozanski.
“Changing one’s diet is extremely important and potentially beneficial in many ways, and being able to say to a patient with atherosclerosis that we have data that shows you can halt the progression of the disease can be extraordinarily encouraging to many patients,” he noted.
“When people have disease, they very often gravitate toward drugs, but continuing to emphasize lifestyle changes in these people is extremely important,” he added.
The CORDIOPREV study was supported by the Fundación Patrimonio Comunal Olivarero. Dr. Yubero-Serrano and Dr. Rozanski disclosed no relevant financial relationships.

Psychiatrists’ income, wealth gain ground despite COVID-19 challenges
Although many physicians endured pandemic-related income struggles in 2020, psychiatrists are doing fairly well with building their nest egg and paying down debt, according to the Medscape Psychiatrist Wealth and Debt Report 2021.
Surprisingly, despite COVID-19, psychiatrists’ income improved somewhat this year – from $268,000 in 2020 to $275,000 in 2021.
However, that still puts psychiatrists among the lower-paid specialists.
The highest-paying specialty is plastic surgery ($526,000), followed by orthopedics and orthopedic surgery ($511,000) and cardiology ($459,000), according to the overall Medscape Physician Wealth and Debt Report 2021. The report is based on responses from nearly 18,000 physicians in 29 specialties. All were surveyed between Oct. 6, 2020, and Feb. 11, 2021.
Psychiatrists’ overall wealth gained some ground over the past year, with 40% reporting a net worth of $1 million to $5 million this year – up from 38% last year. Just 6% of psychiatrists have a net worth north of $5 million, up slightly from 5% last year.
Keeping up with bills
based in St. Louis Park, Minn. He noted that the rise in the stock market also played a role, with the S&P 500 finishing the year up over 18%.
“I’ve seen clients accumulate cash, which has added to their net worth. They cut back on spending because they were worried about big declines in income and also because there was simply less to spend money on,” Dr. Greenwald said.
The percentage of psychiatrists with a net worth under $500,000 decreased from 37% last year to 32% this year. Psychiatry is still among the specialties reporting a high percentage of members with net worth below $500,000.
But gender matters. Earnings overall are higher for male than female psychiatrists, and that is reflected in net worth. Fewer female than male psychiatrists are worth more than $5 million (4% vs. 7%), and more female psychiatrists have a net worth of less than $500,000 (41% vs. 26%).
As in prior years, most psychiatrists are paying down a home mortgage on their primary residence (66%). Psychiatrists’ mortgage payments span a wide range, from less than $100,000 (23%) to more than $500,000 (15%). However, 27% report having no mortgage.
Mortgage aside, other top expenses or debts for psychiatrists are car loan payments (36%), paying off college and medical school debt (26%), credit card debt (25%), and medical expenses for self or loved ones (19%).
Other expenses include college tuition for children (16%), car lease payments (14%), mortgage on a second home (13%), private-school tuition for a child (12%), and child care (12%).
Despite some financially challenging months, the vast majority of psychiatrists (94%) kept up with paying their bills.
That’s better than what much of America experienced. According to a U.S. Census Bureau survey conducted last July, roughly 25% of adults missed a mortgage or rent payment because of COVID-related difficulties.
About half of psychiatrists pool their income to pay for bills. One-quarter do not have joint accounts with a spouse or partner.
Spender or saver?
About three-quarters of psychiatrists continued to spend as usual in 2020. About one-quarter took significant steps to lower their expenses, such as refinancing their home or moving to a less costly home.
In line with prior Medscape surveys, about half of psychiatrists have a general idea of how much they spend and on what, but they do not track or formalize it.
According to a recent survey by Intuit, only 35% of Americans say they know how much they spent last month. Viewed by age, 27% of millennials, 34% of Gen Xers, and 46% of baby boomers knew how much they spent.
Many psychiatrists have a higher-than-average number of credit cards; 42% have at least five. By comparison, the average American has four.
Savings was mixed for psychiatrists this past year; 61% put in the same amount or more each month into their 401(k) plans, but 33% put in less money, compared with last year.
For taxable savings accounts, half of psychiatrists put the same amount or more into after-tax accounts – but 22% put in less money, compared with last year. Another one-quarter did not use these savings accounts at all.
The percentage of psychiatrists who experienced losses because of practice problems rose from 6% to 9% in the past year. Much of that was likely because of COVID. However, about the same percentage reported no financial losses this year (76%), compared with last year (75%).
The vast majority of psychiatrists report living within or below their means; only 5% live above their means.
“There are certainly folks who believe that, as long as they pay off their credit card each month and contribute to their 401(k) enough to get their employer match, they’re doing okay,” Dr. Greenwald said.
However, “living within one’s means is having a 3-6 months’ emergency fund; saving at least 20% of gross income toward retirement; adequately funding 529 college accounts; and, for younger docs, paying down high-interest-rate debt at a good clip,” he added.

‘No justification’ for suicide warning on all antiseizure meds
, new research shows. “There appears to be no justification for the FDA to label every new antiseizure medication with a warning that it may increase risk of suicidality,” said study investigator Michael R. Sperling, MD, professor of neurology, Thomas Jefferson University, Philadelphia.
“How many patients are afraid of their medication and do not take it because of the warning – and are consequently at risk because of that? We do not know, but have anecdotal experience that this is certainly an issue,” Dr. Sperling, who is director of the Jefferson Comprehensive Epilepsy Center, added.
The study was published online August 2 in JAMA Neurology.
Blanket warning
In 2008, the FDA issued an alert stating that antiseizure medications increase suicidality. The alert was based on pooled data from placebo-controlled clinical trials that included 11 antiseizure medications – carbamazepine, felbamate, gabapentin, lamotrigine, levetiracetam, oxcarbazepine, pregabalin, tiagabine, topiramate, valproate, and zonisamide.
The meta-analytic review showed that, compared with placebo, antiseizure medications nearly doubled suicide risk among patients treated for epilepsy, psychiatric disorders, and other diseases. As a result of the FDA study, all antiseizure medications that have been approved since 2008 carry a warning for suicidality.
However, subsequent analyses did not show the same results, Dr. Sperling and colleagues noted.
“Pivotal” antiseizure medication epilepsy trials since 2008 have evaluated suicidality prospectively. Since 2011, trials have included the validated Columbia Suicidality Severity Rating Scale, they noted.
Meta analysis showed no increased risk
Dr. Sperling and colleagues conducted a meta-analysis of 17 randomized placebo-controlled epilepsy trials of five antiseizure medications approved since 2008. These antiseizure medications were eslicarbazepine, perampanel, brivaracetam, cannabidiol, and cenobamate. The trials involved 5,996 patients, including 4,000 who were treated with antiseizure medications and 1,996 who were treated with placebo.
Confining the analysis to epilepsy trials avoids potential confounders, such as possible differences in suicidality risks between different diseases, the researchers noted.
They found no evidence of increased risk for suicidal ideation (overall risk ratio, antiseizure medications vs. placebo: 0.75; 95% confidence interval: 0.35-1.60) or suicide attempt (risk ratio, 0.75; 95% CI: 0.30-1.87) overall or for any individual antiseizure medication.
Suicidal ideation occurred in 12 of 4,000 patients treated with antiseizure medications (0.30%), versus 7 of 1,996 patients treated with placebo (0.35%) (P = .74). Three patients who were treated with antiseizure medications attempted suicide; no patients who were treated with placebo attempted suicide (P = .22). There were no completed suicides.
“There is no current evidence that the five antiseizure medications evaluated in this study increase suicidality in epilepsy and merit a suicidality class warning,” the investigators wrote. When prescribed for epilepsy, “evidence does not support the FDA’s labeling practice of a blanket assumption of increased suicidality,” said Dr. Sperling.
“Our findings indicate the nonspecific suicide warning for all epilepsy drugs is simply not justifiable,” he said. “The results are not surprising. Different drugs affect cells in different ways. So there’s no reason to expect that every drug would increase suicide risk for every patient,” Dr. Sperling said in a statement.
“It’s important to recognize that epilepsy has many causes – perinatal injury, stroke, tumor, head trauma, developmental malformations, genetic causes, and others – and these underlying etiologies may well contribute to the presence of depression and suicidality in this population,” he said in an interview. “Psychodynamic influences also may occur as a consequence of having seizures. This is a complicated area, and drugs are simply one piece of the puzzle,” he added.
Dr. Sperling said the FDA has accomplished “one useful thing with its warning – it highlighted that physicians and other health care providers must pay attention to their patients’ psychological state, ask questions, and treat accordingly.”
The study had no specific funding. Dr. Sperling has received grants from Eisai, Medtronic, Neurelis, SK Life Science, Sunovion, Takeda, Xenon, Cerevel Therapeutics, UCB Pharma, and Engage Pharma; personal fees from Neurelis, Medscape, Neurology Live, International Medical Press, UCB Pharma, Eisai, Oxford University Press, and Projects in Knowledge.

“How many patients are afraid of their medication and do not take it because of the warning – and are consequently at risk because of that? We do not know, but have anecdotal experience that this is certainly an issue,” Dr. Sperling, who is director of the Jefferson Comprehensive Epilepsy Center, added.
The study was published online August 2 in JAMA Neurology.
Blanket warning
In 2008, the FDA issued an alert stating that antiseizure medications increase suicidality. The alert was based on pooled data from placebo-controlled clinical trials that included 11 antiseizure medications – carbamazepine, felbamate, gabapentin, lamotrigine, levetiracetam, oxcarbazepine, pregabalin, tiagabine, topiramate, valproate, and zonisamide.
The meta-analytic review showed that, compared with placebo, antiseizure medications nearly doubled suicide risk among patients treated for epilepsy, psychiatric disorders, and other diseases. As a result of the FDA study, all antiseizure medications that have been approved since 2008 carry a warning for suicidality.
However, subsequent analyses did not show the same results, Dr. Sperling and colleagues noted.
“Pivotal” antiseizure medication epilepsy trials since 2008 have evaluated suicidality prospectively. Since 2011, trials have included the validated Columbia Suicidality Severity Rating Scale, they noted.
Meta analysis showed no increased risk
Dr. Sperling and colleagues conducted a meta-analysis of 17 randomized placebo-controlled epilepsy trials of five antiseizure medications approved since 2008. These antiseizure medications were eslicarbazepine, perampanel, brivaracetam, cannabidiol, and cenobamate. The trials involved 5,996 patients, including 4,000 who were treated with antiseizure medications and 1,996 who were treated with placebo.

Brain memory signals appear to regulate metabolism
Rhythmic brain signals that help encode memories also appear to influence blood sugar levels and may regulate the timing of the release of hormones, early, pre-clinical research shows.
“Our study is the first to show how clusters of brain cell firing in the hippocampus may directly regulate metabolism,” senior author György Buzsáki, MD, PhD, professor, department of neuroscience and physiology, NYU Grossman School of Medicine and NYU Langone Health, said in a news release.
“Evidence suggests that the brain evolved, for reasons of efficiency, to use the same signals to achieve two very different functions in terms of memory and hormonal regulation,” added corresponding author David Tingley, PhD, a post-doctoral scholar in Dr. Buzsáki’s lab.
The study was published online August 11 in Nature.
It’s recently been discovered that populations of hippocampal neurons fire within milliseconds of each other in cycles. This firing pattern is called a “sharp wave ripple” for the shape it takes when captured graphically by electroencephalogram.
In their study, Dr. Buzsáki, Dr. Tingley, and colleagues observed that clusters of sharp wave ripples recorded from the hippocampus of rats were “reliably” and rapidly, followed by decreases in blood sugar concentrations in the animals.
“This correlation was not dependent on circadian, ultradian, or meal-triggered fluctuations; it could be mimicked with optogenetically induced ripples in the hippocampus, but not in the parietal cortex, and was attenuated to chance levels by pharmacogenetically suppressing activity of the lateral septum (LS), the major conduit between the hippocampus and hypothalamus,” the researchers report.
These observations suggest that hippocampal sharp wave ripples may regulate the timing of the release of hormones, possibly including insulin, by the pancreas and liver, as well as other hormones by the pituitary gland, the researchers note.
As sharp wave ripples mostly occur during non-rapid eye movement sleep, the impact of sleep disturbance on sharp wave ripples may provide a mechanistic link between poor sleep and high blood sugar levels seen in type 2 diabetes, they suggest.
“There are a couple of experimental studies showing that if you deprive a young healthy person from sleep [for 48 hours], their glucose tolerance resembles” that of a person with diabetes, Dr. Buzsáki noted in an interview.
Moving forward, the researchers will seek to extend their theory that several hormones could be affected by nightly sharp wave ripples.
The research was funded by National Institutes of Health. The authors have disclosed no relevant financial relationships.
