A new study provides more evidence that endocarditis associated with drug use is a significant and growing health concern, and further demonstrates that this risk has been exacerbated by the COVID-19 pandemic.

The rate of infective endocarditis among individuals in the United States with opioid or cocaine use disorder increased in the 11-year period 2011 to 2022, with the steepest increase logged during the COVID-19 pandemic (2021-2022), according to the study.

A diagnosis of COVID-19 more than doubled the risk for a new diagnosis of endocarditis in patients with either cocaine (hazard ratio, 2.24) or opioid use disorder (HR, 2.23).

“Our data suggests that, in addition to the major social disruption from the pandemic, including disrupted access to health care, COVID-19 infection itself is a significant risk factor for new diagnosis of endocarditis in drug using populations,” authors Nora Volkow, MD, director of the National Institute on Drug Abuse, and colleagues wrote.

“Drug-using populations, particularly those who use cocaine or opioids, have some of the highest risk for endocarditis, and here we show that having a COVID-19 diagnoses further increases this risk,” they added.

The study was published online in Molecular Psychiatry.

The researchers analyzed electronic health record data collected from January 2011 to August 2022 for more than 109 million people across the United States, including more than 736,000 with an opioid use disorder and more than 379,000 with a cocaine use disorder.

In 2011, there were 4 cases of endocarditis per day for every 1 million people with opioid use disorder. By 2022, the rate had increased to 30 cases per day per 1 million people with opioid use disorder.

For people with cocaine use disorder, cases of endocarditis increased from 5 per 1 million in 2011 to 23 per 1 million in 2022.

Among individuals with cocaine or opioid use disorder, the risk of being hospitalized within 180 days following a diagnosis of endocarditis was higher in those with than without COVID-19 (67.5% vs. 58.7%; HR, 1.21). 

The risk of dying within 180 days following new diagnosis of endocarditis was also higher in those with than without COVID-19 (9.2% vs. 8%; HR, 1.16).

The study also showed that Black and Hispanic individuals had a lower risk for COVID-19-associated endocarditis than non-Hispanic White individuals, which is consistent with a higher prevalence of injection drug use in non-Hispanic White populations, compared with Black or Hispanic populations, the researchers pointed out.

Dr. Volkow and colleagues said their findings highlight the need to screen drug users for endocarditis and link them to infectious disease and addiction treatment if they contract COVID-19.

“People with substance use disorder already face major impediments to proper health care due to lack of access and stigma,” Dr. Volkow said in a news release. 

“Proven techniques like syringe service programs, which help people avoid infection from reused or shared injection equipment, can help prevent this often fatal and costly condition,” Dr. Volkow added.

The authors said it will also be important to determine exactly how SARS-CoV-2 viral infection exacerbates the risk for endocarditis in drug users.

Support for the study was provided by the National Institute on Aging, National Institute on Alcohol Abuse and Alcoholism, the Clinical and Translational Science Collaborative of Cleveland, and the National Cancer Institute Case Comprehensive Cancer Center. The authors reported no relevant financial relationships.

Three cups of tea, two biscuit packs, and a Christmas study from the BMJ

Warning: The following content may contain excessive Britishness. Continue at your own risk.

It’s no secret that the world economy is in an … interesting spot right now. Belt tightening is occurring around the world despite the holiday season, and hospitals across the pond in Great Britain are no exception.

It was a simple sign that prompted the study, published in the Christmas edition of the BMJ: “Please do not take excessive quantities of these refreshments.” And if we all know one thing, you do not get between Brits and their tea and biscuits. So the researchers behind the study drafted a survey and sent it around to nearly 2,000 British health care workers and asked what they considered to be excessive consumption of work-provided hot drinks and biscuits.

In the hot drinks department (tea and coffee, though we appreciate the two people who voiced a preference for free hot whiskey, if it was available) the survey participants decreed that 3.32 drinks was the maximum before consumption became excessive. That’s pretty close to the actual number of hot drinks respondents drank daily (3.04), so it’s pretty fair to say that British health care workers do a good job of self-limiting.

It’s much the same story with biscuits: Health care workers reported that consuming 2.25 packets of free biscuits would be excessive. Notably, doctors would take more than nondoctors (2.35 vs. 2.14 – typical doctor behavior), and those who had been in their role for less than 2 years would consume nearly 3 packets a day before calling it quits.

The study did not include an official cost analysis, but calculations conducted on a biscuit wrapper (that’s not a joke, by the way) estimated that the combined cost for providing every National Health Service employee with three free drinks and two free biscuit packages a day would be about 160 million pounds a year. Now, that’s a lot of money for tea and biscuits, but, they added, it’s a meager 0.1% of the NHS annual budget. They also noted that most employees consider free hot drinks a more valuable workplace perk than free support for mental health.

In conclusion, the authors wrote, “As a target for cost-saving initiatives, limiting free refreshment consumption is really scraping the biscuit barrel (although some limits on hot whiskey availability may be necessary), and implementing, or continuing, perks that improve staff morale seems justifiable. … Healthcare employers should allow biscuits and hot drinks to be freely available to staff, and they should leave these grateful recipients to judge for themselves what constitutes reasonable consumption.”

Now there’s a Christmas sentiment we can all get behind.
 

We come not to bury sugar, but to improve it

When we think about sugar, healthy isn’t the first thing that comes to mind. Research also shows that artificial sweeteners, as well as processed foods in general, are bad for your body and brain. People, however, love the stuff. That’s why one of the leading brands in processed foods, Kraft Heinz, partnered with the Wyss Institute for Biologically Inspired Engineering at Harvard to find a way to reduce consumers’ sugar consumption.

Vassiliy Vassilenko/thinkstockphotos.com

The question that Kraft Heinz presented to Wyss was this: How could it reduce the fructose in its products without losing the functionality of regular sugar.

The Wyss team’s approach seems pretty simple: Use a naturally occurring enzyme to convert sugar to fiber. The trick was to add the enzymes into the food so they could convert the sugar to fiber after being consumed. The enzymes also needed to be able to be added to existing food products without changing their existing recipes, Kraft Heinz insisted.

How does it work? The crafted enzyme is encapsulated to remain dormant in the food until exposed to an increased pH level, as is found in the GI tract between the stomach and the intestine. It reduces the amount of sugar absorbed in the bloodstream and creates a healthy prebiotic fiber, the institute explained.

This opens a whole new window for consumers. People with diabetes can enjoy their favorite cookies from time to time, while parents can feel less guilty about their children bathing their chicken nuggets in unholy amounts of ketchup.
 

New genes, or not new genes? That is the question

… and the police report that no capybaras were harmed in the incident. What a relief. Now Action News 8 brings you Carol Espinosa’s exclusive interview with legendary scientist and zombie, Charles Darwin.

Carol: Thanks, Daryl. Tell us, Prof. Darwin, what have you been up to lately?

Sleep-disordered breathing was significantly associated with increased odds of preeclampsia and with greater arterial stiffness in high-risk pregnancies, based on data from 181 individuals.

The intermittent hypoxia resulting from sleep-disordered breathing (SDB) has been linked to cardiovascular disease and hypertension, wrote Kim Phan, PhD, of McGill University, Montreal, and colleagues.

SDB has been associated with increased preeclampsia risk, and women with preeclampsia show increased arterial stiffness, but an association between SDB and arterial stiffness in pregnancy has not been explored, they said.

In a study published in the American Journal of Obstetrics & Gynecology, the researchers reviewed data from 181 women with high-risk singleton pregnancies recruited from two tertiary obstetrics clinics in Montreal. High-risk pregnancy was defined as meeting at least one of the following criteria: age 35 years and older, body mass index 25 kg/m² or higher, chronic hypertension, preexisting diabetes mellitus, preexisting renal disease, or personal or first-degree relative with a history of preeclampsia.

Participants were assessed at each trimester via the Epworth Sleepiness Scale, Pittsburgh Sleep Quality Index, and Restless Legs Syndrome questionnaire. Sleep-disordered breathing was defined as loud snoring or witnessed sleep apneas at least three times a week. Arterial stiffness was assessed via applanation tonometry every 4 weeks from baseline throughout pregnancy.

Overall, 23% of the study population met the criteria for SDB; SDB in the first or second trimester was associated with a significantly increased risk of preeclampsia (odds ratio 3.4). The effect of SDB on preeclampsia was increased in women who reported excessive daytime sleepiness, defined as scores higher than 10 on the Epworth Sleepiness Scale. The odds ratio for preeclampsia in the first or second trimester increased to 5.7 in women with hypersomnolence in addition to SDB. The risk of preeclampsia was even higher (OR 8.2) in the third trimester.

Self-reported total sleep time decreased in the second and third trimesters compared with the first, but reports of excessive daytime sleepiness remained consistent throughout the pregnancies, the researchers noted.

The results highlight the need to screen pregnant women for SDB in all three trimesters; however, “future studies will need to assess the incremental benefit of integrating SDB into risk assessment calculators in pregnancy,” the researchers wrote in their discussion. Randomized trials are needed to determine the value of interventions such as continuous positive airway pressure to reduce arterial stiffness and the risks of hypertensive disorders of pregnancy, they said. More data also are needed to examine the role of excessive daytime sleepiness as a modifier of arterial stiffness and preeclampsia risk, they noted.

The findings were limited by the prospective design, which prevents conclusions of causality, the researchers noted. Other limitations included the focus on high-risk pregnancy, which may limit generalizability, and the use of symptoms, not sleep recordings, to identify SDB, they said.

However, the results show an independent association between SDB and arterial stiffness during pregnancy, and offer potentially useful insights into the mechanisms of SDB-associated cardiovascular conditions, they noted.

“This work may inform future studies exploring the value of using arterial stiffness, as an early noninvasive indicator of subclinical vascular dysfunction in pregnant women with SDB,” they concluded.

The study was supported by the Fonds de recherche du Quebec – Sante (FRQS), Heart and Stroke Foundation of Canada, McGill University’s academic enrichment fund, and the Canadian Foundation for Women’s Health. The researchers had no financial conflicts to disclose.

This holiday season, I am looking forward to spending some time with family, as I have in the past. As I have chatted with others, many friends are looking forward to events that are potentially larger and potentially returning to prepandemic type gatherings.

Gathering is important and can bring joy, sense of community, and love to the lives of many. Unfortunately, the risks associated with gathering are not over. We are currently facing what many are calling a “tripledemic” as our country faces many cases of respiratory syncytial virus (RSV), COVID-19, and influenza at the same time.

During the first week of December, cases of influenza were rising across the country¹ and were rising faster than in previous years. Although getting the vaccine is an important method of influenza prevention and is recommended for everyone over the age of 6 months with rare exception, many have not gotten their vaccine this year.

Thus far, “nearly 50% of reported flu-associated hospitalizations in women of childbearing age have been in women who are pregnant.” We are seeing this at a time with lower-than-average uptake of influenza vaccine leaving both the pregnant persons and their babies unprotected. In addition to utilizing vaccines as prevention, isolating when ill, cleaning surfaces, and practicing good hand hygiene can all decrease transmission.

RSV

In addition to rises of influenza, there are currently high rates of RSV in various parts of the country. Prior to 2020, RSV typically started in the fall and peaked in the winter months. However, since the pandemic, the typical seasonal pattern has not returned, and it is unclear when it will. Although RSV hits the very young, the old, and the immunocompromised the most, RSV can infect anyone. Unfortunately, we do not currently have a vaccine for everyone against this virus. Prevention of transmission includes, as with flu, isolating when ill, cleaning surfaces, and washing hands.²

COVID-19

Of course, the effects of the COVID-19 pandemic are also still here as well. During the first week of December, the CDC reported rising cases of COVID across the country. Within the past few months, there have been several developments, though, for protection. There are now bivalent vaccines available as either third doses or booster doses approved for all persons over 6 months of age. As of the first week of December, only 13.5% of those aged 5 and over had received an updated booster.

There is currently wider access to rapid testing, including at-home testing, which can allow individuals to identify if COVID positive. Additionally, there is access to medication to decrease the likelihood of severe disease – though this does not take the place of vaccinations.

If anyone does test positive for COVID, they should follow the most recent quarantine guidelines including wearing a well-fitted mask when they do begin returning to activities.³

With rising cases of all three of these viruses, some may be asking how we can safely gather. There are several things to consider and do to enjoy our events. The first thing everyone can do is to receive updated vaccinations for both influenza and COVID-19 if eligible. Although it may take some time to be effective, vaccination is still one of our most effective methods of disease prevention and is important this winter season. Vaccinations can also help decrease the risk of severe disease.

Although many have stopped masking, as cases rise, it is time to consider masking particularly when community levels of any of these viruses are high. Masks help with preventing and spreading more than just COVID-19. Using them can be especially important for those going places such as stores and to large public gatherings and when riding on buses, planes, or trains.
 

In summary

Preventing exposure by masking can help keep individuals healthy prior to celebrating the holidays with others. With access to rapid testing, it makes sense to consider testing prior to gathering with friends and family. Most importantly, although we all are looking forward to spending time with our loved ones, it is important to stay home if not feeling well. Following these recommendations will allow us to have a safer and more joyful holiday season.

This holiday season, I am looking forward to spending some time with family, as I have in the past. As I have chatted with others, many friends are looking forward to events that are potentially larger and potentially returning to prepandemic type gatherings.

Gathering is important and can bring joy, sense of community, and love to the lives of many. Unfortunately, the risks associated with gathering are not over. We are currently facing what many are calling a “tripledemic” as our country faces many cases of respiratory syncytial virus (RSV), COVID-19, and influenza at the same time.

During the first week of December, cases of influenza were rising across the country¹ and were rising faster than in previous years. Although getting the vaccine is an important method of influenza prevention and is recommended for everyone over the age of 6 months with rare exception, many have not gotten their vaccine this year.

Cardiac injury caused by COVID-19 may be much less common than suggested previously, a new study has found.

The study examined cardiac MRI scans in 31 patients before and after having COVID-19 infection and found no new evidence of myocardial injury in the post-COVID scans relative to the pre-COVID scans.

“To the best of our knowledge this is the first cardiac MRI study to assess myocardial injury pre- and post-COVID-19,” the authors stated.

They say that while this study cannot rule out the possibility of rare events of COVID-19–induced myocardial injury, “the complete absence of de novo late gadolinium enhancement lesions after COVID-19 in this cohort indicates that outside special circumstances, COVID-19–induced myocardial injury may be much less common than suggested by previous studies.”

The study was published online in JACC: Cardiovascular Imaging.

Coauthor Till F. Althoff, MD, Cardiovascular Institute, Clínic–University Hospital Barcelona, said in an interview that previous reports have found a high rate of cardiac lesions in patients undergoing imaging after having had COVID-19 infection.

“In some reports, this has been as high as 80% of patients even though they have not had severe COVID disease. These reports have been interpreted as showing the majority of patients have some COVID-induced cardiac damage, which is an alarming message,” he commented.

However, he pointed out that the patients in these reports did not undergo a cardiac MRI scan before they had COVID-19 so it wasn’t known whether these cardiac lesions were present before infection or not.

To try and gain more accurate information, the current study examined cardiac MRI scans in the same patients before and after they had COVID-19.

The researchers, from an arrhythmia unit, made use of the fact that all their patients have cardiac MRI data, so they used their large registry of patients in whom cardiac MRI had been performed, and cross referenced this to a health care database to identify those patients who had confirmed COVID-19 after they obtaining a cardiac scan at the arrhythmia unit. They then conducted another cardiac MRI scan in the 31 patients identified a median of 5 months after their COVID-19 infection.

“These 31 patients had a cardiac MRI scan pre-COVID and post COVID using exactly the same scanner with identical sequences, so the scans were absolutely comparable,” Dr. Althoff noted.

Of these 31 patients, 7 had been hospitalized at the time of acute presentation with COVID-19, of whom 2 required intensive care. Most patients (29) had been symptomatic, but none reported cardiac symptoms.

Results showed that, on the post–COVID-19 scan, late gadolinium enhancement lesions indicative of residual myocardial injury were encountered in 15 of the 31 patients (48%), which the researchers said is in line with previous reports.

However, intraindividual comparison with the pre–COVID-19 cardiac MRI scans showed all these lesions were preexisting with identical localization, pattern, and transmural distribution, and thus not COVID-19 related.

Quantitative analyses, performed independently, detected no increase in the size of individual lesions nor in the global left ventricular late gadolinium enhancement extent.

Comparison of pre- and post COVID-19 imaging sequences did not show any differences in ventricular functional or structural parameters.

“While this study only has 31 patients, the fact that we are conducting intra-individual comparisons, which rules out bias, means that we don’t need a large number of patients for reliable results,” Dr. Althoff said.

“These types of lesions are normal to see. We know that individuals without cardiac disease have these types of lesions, and they are not necessarily an indication of any specific pathology. I was kind of surprised by the interpretation of previous data, which is why we did the current study,” he added.

Dr. Althoff acknowledged that some cardiac injury may have been seen if much larger numbers of patients had been included. “But I think we can say from this data that COVID-induced cardiac damage is much less of an issue than we may have previously thought,” he added.

He also noted that most of the patients in this study had mild COVID-19, so the results cannot be extrapolated to severe COVID-19 infection.

However, Dr. Althoff pointed out that all the patients already had atrial fibrillation, so would have been at higher risk of cardiac injury from COVID-19.

“These patients had preexisting cardiac risk factors, and thus they would have been more susceptible to both a more severe course of COVID and an increased risk of myocardial damage due to COVID. The fact that we don’t find any myocardial injury due to COVID in this group is even more reassuring. The general population will be at even lower risk,” he commented.

“I think we can say that, in COVID patients who do not have any cardiac symptoms, our study suggests that the incidence of cardiac injury is very low,” Dr. Althoff said.

“Even in patients with severe COVID and myocardial involvement reflected by increased troponin levels, I wouldn’t be sure that they have any residual cardiac injury. While it has been reported that cardiac lesions have been found in such patients, pre-COVID MRI scans were not available so we don’t know if they were there before,” he added.

“We do not know the true incidence of cardiac injury after COVID, but I think we can say from this data that it is definitely not anywhere near the 40%-50% or even greater that some of the previous reports have suggested,” he stated.

Dr. Althoff suggested that, based on these data, some of the recommendations based on previous reports such the need for follow-up cardiac scans and caution about partaking in sports again after COVID-19 infection, are probably not necessary.

“Our data suggest that these concerns are unfounded, and we need to step back a bit and stop alarming patients about the risk of cardiac damage after COVID,” he said. “Yes, if patients have cardiac symptoms during or after COVID infection they should get checked out, but I do not think we need to do a cardiac risk assessment in patients without cardiac symptoms in COVID.”

This work is supported in part by grants from Instituto de Salud Carlos III, the Spanish government, Madrid, and Fundació la Marató de TV3 in Catalonia. Dr. Althoff has received research grants for investigator-initiated trials from Biosense Webster.

New COVID-19 cases in children jumped by 66% during the first 2 weeks of December after an 8-week steady period lasting through October and November, according to the American Academy of Pediatrics and the Children’s Hospital Association.

New cases reached close to 48,000 for the most recent reporting week, Dec. 9-15, after rising to just over 41,000 the previous week and totaling less than 29,000 for the week of Nov. 25 to Dec. 1. That increase of almost 19,000 cases is the largest over a 2-week period since late July, the AAP and CHA said in their weekly COVID report based on data collected from state and territorial health department websites.

[This publication has been following the AAP/CHA report since the summer of 2020 and continues to share the data for the sake of consistency, but it must be noted that a number of states are no longer updating their public COVID dashboards. As a result, there is now a considerable discrepancy between the AAP/CHA weekly figures and those reported by the Centers for Disease Control and Prevention, which has no such limitations on state data.]

The situation involving new cases over the last 2 weeks is quite different from the CDC’s perspective. The agency does not publish a weekly count, instead offering cumulative cases, which stood at almost 16.1 million as of Dec. 14. Calculating a 2-week total puts the new-case count for Dec. 1-14 at 113,572 among children aged 0-17 years. That is higher than the AAP/CHA count (88,629) for roughly the same period, but it is actually lower than the CDC’s figure (161,832) for the last 2 weeks of November.

The CDC data, in other words, suggest that new cases have gone down in the last 2 weeks, while the AAP and CHA, with their somewhat limited perspective, announced that new cases have gone up.

One COVID-related measure from the CDC that is not contradicted by other sources is hospitalization rates, which had climbed from 0.16 new admissions in children aged 0-17 years with confirmed COVID per 100,000 population on Oct. 22 to 0.29 per 100,000 on Dec. 9. Visits to the emergency department with diagnosed COVID, meanwhile, have been fairly steady so far through December in children, according to the CDC.

That increase of almost 19,000 cases is the largest over a 2-week period since late July, the AAP and CHA said in their weekly COVID report based on data collected from state and territorial health department websites.

[This publication has been following the AAP/CHA report since the summer of 2020 and continues to share the data for the sake of consistency, but it must be noted that a number of states are no longer updating their public COVID dashboards. As a result, there is now a considerable discrepancy between the AAP/CHA weekly figures and those reported by the Centers for Disease Control and Prevention, which has no such limitations on state data.]

The situation involving new cases over the last 2 weeks is quite different from the CDC’s perspective. The agency does not publish a weekly count, instead offering cumulative cases, which stood at almost 16.1 million as of Dec. 14. Calculating a 2-week total puts the new-case count for Dec. 1-14 at 113,572 among children aged 0-17 years. That is higher than the AAP/CHA count (88,629) for roughly the same period, but it is actually lower than the CDC’s figure (161,832) for the last 2 weeks of November.

The CDC data, in other words, suggest that new cases have gone down in the last 2 weeks, while the AAP and CHA, with their somewhat limited perspective, announced that new cases have gone up.

One COVID-related measure from the CDC that is not contradicted by other sources is hospitalization rates, which had climbed from 0.16 new admissions in children aged 0-17 years with confirmed COVID per 100,000 population on Oct. 22 to 0.29 per 100,000 on Dec. 9. Visits to the emergency department with diagnosed COVID, meanwhile, have been fairly steady so far through December in children, according to the CDC.

Two years ago, when the first COVID-19 vaccines were administered, marked a game-changing moment in the fight against the pandemic. But it also was a significant moment for messenger RNA (mRNA) technology, which up until then had shown promise but had never quite broken through. 

Now, scientists hope to use this technology to develop more vaccines, with those at the University of Pennsylvania hoping to use that technology to pioneer yet another first: a universal flu vaccine that can protect us against all flu types, not just a select few. 

It’s the latest advance in a new age of vaccinology, where vaccines are easier and faster to produce, as well as more flexible and customizable. 

“It’s all about covering the different flavors of flu in a way the current vaccines cannot do,” says Ofer Levy, MD, PhD, director of the Precision Vaccines Program at Boston Children’s Hospital, who is not involved with the UPenn research. “The mRNA platform is attractive here given its scalability and modularity, where you can mix and match different mRNAs.” 

A recent paper, published in Science, reports successful animal tests of the experimental vaccine, which, like the Pfizer-BioNTech and Moderna COVID vaccines, relies on mRNA. But the idea is not to replace the annual flu shot. It’s to develop a primer that could be administered in childhood, readying the body’s B cells and T cells to react quickly if faced with a flu virus. 

It’s all part of a National Institutes of Health–funded effort to develop a universal flu vaccine, with hopes of heading off future flu pandemics. Annual shots protect against flu subtypes known to spread in humans. But many subtypes circulate in animals, like birds and pigs, and occasionally jump to humans, causing pandemics. 

“The current vaccines provide very little protection against these other subtypes,” says lead study author Scott Hensley, PhD, a professor of microbiology at UPenn. “We set out to make a vaccine that would provide some level of immunity against essentially every influenza subtype we know about.” 

That’s 20 subtypes altogether. The unique properties of mRNA vaccines make immune responses against all those antigens possible, Dr. Hensley says. 

Old-school vaccines introduce a weakened or dead bacteria or virus into the body, but mRNA vaccines use mRNA encoded with a protein from the virus. That’s the “spike” protein for COVID, and for the experimental vaccine, it’s hemagglutinin, the major protein found on the surface of all flu viruses.

Mice and ferrets that had never been exposed to the flu were given the vaccine and produced high levels of antibodies against all 20 flu subtypes. Vaccinated mice exposed to the exact strains in the vaccine stayed pretty healthy, while those exposed to strains not found in the vaccine got sick but recovered quickly and survived. Unvaccinated mice exposed to the flu strain died. 

The vaccine seems to be able to “induce broad immunity against all the different influenza subtypes,” Dr. Hensley says, preventing severe illness if not infection overall. 

Still, whether it could truly stave off a pandemic that hasn’t happened yet is hard to say, Dr. Levy cautions. 

“We are going to need to better learn the molecular rules by which these vaccines protect,” he says.

But the UPenn team is forging ahead, with plans to test their vaccine in human adults in 2023 to determine safety, dosing, and antibody response.

More than a quarter of patients who were shot by assailants with guns had their injuries mislabeled as “unintentional” at hospital discharge, according to a review of more than 1,200 cases at three U.S. trauma centers.

These coding inaccuracies could distort our understanding of gun violence in the United States and make it seem like accidental shootings are more common than they really are, researchers reported in JAMA Network Open.

“The systematic error in intent classification is not widely known or acknowledged by researchers in this field,” Philip J. Cook, PhD, of Duke University, Durham, N.C., and Susan T. Parker, of the University of Michigan, Ann Arbor, wrote in an invited commentary about the new findings. “The bulk of all shootings, nonfatal and fatal together, are assaults, which is to say the result of one person intentionally shooting another. An accurate statistical portrait thus suggests that gun violence is predominantly a crime problem.”

In 2020, 79% of all homicides and 53% of all suicides involved firearms, the CDC reported. Gun violence is now the leading cause of death for children in the United States, government data show.

For the new study, Matthew Miller, MD, ScD, of Northeastern University and the Harvard Injury Control Research Center in Boston, and his colleagues examined how International Classification of Diseases (ICD) codes may misclassify the intent behind gunshot injuries.

Dr. Miller’s group looked at 1,227 incidents between 2008 and 2019 at three major trauma centers – Brigham and Women’s Hospital and Massachusetts General Hospital, both in Boston, and Harborview Medical Center in Seattle.

Of those shootings, 837 (68.2%) involved assaults, 168 (13.5%) were unintentional, 124 (9.9%) were deliberate self-harm, and 43 (3.4%) were instances of legal intervention, based on the researchers’ review of medical records.

ICD codes at discharge, however, labeled 581 cases (47.4%) as assaults and 432 (35.2%) as unintentional.

The researchers found that 234 of the 837 assaults (28%) and 9 of the 43 legal interventions (20.9%) were miscoded as unintentional. This problem occurred even when the “medical narrative explicitly indicated that the shooting was an act of interpersonal violence,” such as a drive-by shooting or an act of domestic violence, the researchers reported.

Hospital trauma registrars, who detail the circumstances surrounding injuries, were mostly in agreement with the researchers.

Medical coders “would likely have little trouble characterizing firearm injury intent accurately if incentives were created for them to do so,” the authors wrote.

Trends and interventions

Separately, researchers published studies showing that gun violence tends to affect various demographics differently, and that remediating abandoned houses could help reduce gun crime.

Lindsay Young, of the University of Cincinnati, and Henry Xiang, MD, PhD, director of the Center for Pediatric Trauma Research at Nationwide Children’s Hospital in Columbus, Ohio, analyzed rates of firearm deaths from 1981 to 2020.

They found that the rate of firearm-related homicide was five times higher among males than females, and the rate of suicide involving firearms was nearly seven times higher for men, they reported in PLOS ONE.

Black men were the group most affected by homicide, whereas White men were most affected by suicide, they found.

To see if fixing abandoned properties would improve health and reduce gun violence in low-income, Black neighborhoods in Philadelphia, Eugenia C. South, MD, of the University of Pennsylvania, Philadelphia, and colleagues conducted a randomized trial.

They randomly assigned abandoned properties in some areas to undergo full remediation (installing working windows and doors, cleaning trash, and weeding); trash cleanup and weeding only; or no intervention.

“Abandoned houses that were remediated showed substantial drops in nearby weapons violations (−8.43%), gun assaults (−13.12%), and to a lesser extent shootings (−6.96%),” the researchers reported.

The intervention targets effects of segregation that have resulted from “historical and ongoing government and private-sector policies” that lead to disinvestment in Black, urban communities, they wrote. Abandoned houses can be used to store firearms and for other illegal activity. They also can engender feelings of fear, neglect, and stress in communities, the researchers noted.

Dr. Miller’s study was funded by the National Collaborative on Gun Violence Research; coauthors disclosed corporate, government, and university grants. The full list of disclosures can be found with the original article. Editorialists Dr. Cook and Dr. Parker report no relevant financial relationships. Dr. South’s study was funded by the National Institutes of Health. Dr. South and some coauthors disclosed government grants.

The percentage of people in the U.S. getting the latest COVID-19 booster shot has crept up by single digits in the past couple months, despite health officials pleading for people to do so before the Christmas holiday. 

Now, a new poll shows why so few people are willing to roll up their sleeves again.

The most common reasons people give for not getting the latest booster shot is that they “don’t think they need one” (44%) and they “don’t think the benefits are worth it” (37%), according to poll results from the Kaiser Family Foundation. 

The data comes amid announcements by the Centers for Disease Control and Prevention that boosters reduced COVID-19 hospitalizations by up to 57% for U.S. adults and by up to 84% for people age 65 and older. Those figures are just the latest in a mountain of research reporting the public health benefits of COVID-19 vaccines.

Despite all of the statistical data, health officials’ recent vaccination campaigns have proven far from compelling. 

So far, just 15% of people age 12 and older have gotten the latest booster, and 36% of people age 65 and older have gotten it, the CDC’s vaccination trackershows.

Since the start of the pandemic, 1.1 million people in the U.S. have died from COVID-19, with the number of deaths currently rising by 400 per day, The New York Times COVID tracker shows.

Many experts continue to note the need for everyone to get booster shots regularly, but some advocate that perhaps a change in strategy is in order.

“What the administration should do is push for vaccinating people in high-risk groups, including those who are older, those who are immunocompromised and those who have comorbidities,” Paul Offitt, MD, director of the Vaccine Education Center at Children’s Hospital of Philadelphia, told CNN.

Federal regulators have announced they will meet Jan. 26 with a panel of vaccine advisors to examine the current recommended vaccination schedule as well as look at the effectiveness and composition of current vaccines and boosters, with an eye toward the make-up of next-generation shots.

Vaccines are the “best available protection” against hospitalization and death caused by COVID-19, said Peter Marks, MD, PhD, director of the FDA’s Center for Biologics Evaluation and Research, in a statement announcing the planned meeting.

“Since the initial authorizations of these vaccines, we have learned that protection wanes over time, especially as the virus rapidly mutates and new variants and subvariants emerge,” he said. “Therefore, it’s important to continue discussions about the optimal composition of COVID-19 vaccines for primary and booster vaccination, as well as the optimal interval for booster vaccination.”

Those figures are just the latest in a mountain of research reporting the public health benefits of COVID-19 vaccines.

Despite all of the statistical data, health officials’ recent vaccination campaigns have proven far from compelling. 

So far, just 15% of people age 12 and older have gotten the latest booster, and 36% of people age 65 and older have gotten it, the CDC’s vaccination trackershows.

Since the start of the pandemic, 1.1 million people in the U.S. have died from COVID-19, with the number of deaths currently rising by 400 per day, The New York Times COVID tracker shows.

Many experts continue to note the need for everyone to get booster shots regularly, but some advocate that perhaps a change in strategy is in order.

“What the administration should do is push for vaccinating people in high-risk groups, including those who are older, those who are immunocompromised and those who have comorbidities,” Paul Offitt, MD, director of the Vaccine Education Center at Children’s Hospital of Philadelphia, told CNN.

Federal regulators have announced they will meet Jan. 26 with a panel of vaccine advisors to examine the current recommended vaccination schedule as well as look at the effectiveness and composition of current vaccines and boosters, with an eye toward the make-up of next-generation shots.

Vaccines are the “best available protection” against hospitalization and death caused by COVID-19, said Peter Marks, MD, PhD, director of the FDA’s Center for Biologics Evaluation and Research, in a statement announcing the planned meeting.

“Since the initial authorizations of these vaccines, we have learned that protection wanes over time, especially as the virus rapidly mutates and new variants and subvariants emerge,” he said. “Therefore, it’s important to continue discussions about the optimal composition of COVID-19 vaccines for primary and booster vaccination, as well as the optimal interval for booster vaccination.”

Patients with acute ischemic stroke had a worse prognosis if they had also experienced severe obstructive sleep apnea (OSA), based on data from 125 individuals.

OSA is on the rise, and is associated with pathophysiological changes, and data from previous studies suggest that severe OSA doubles the risk of stroke and increases risk of stroke recurrence, according to Juan Xu, PhD, of Soochow University, Suzhou, China, and colleagues.

“There is a high comorbidity between stroke and OSA,” and effective sleep is important to cerebral function recovery, the researchers wrote. Early prediction of stroke prognosis may inform treatment in stroke patients, but the value of OSA as a predictor of functional prognosis has not been explored.

In a study published in Sleep Medicine, the researchers analyzed data from 125 adults with mild to moderate ischemic stroke and OSA. The participants underwent polysomnography within a week of stroke onset between January 2015 and June 2020 and were grouped by severity according to apnea-hypopnea index (AHI) of either less than 30/h (not severe) or 30/h or higher (severe). The mean age of the patients was 58 years, and 87% were men. Approximately one-third of the participants met the criteria for severe OSA.

The researchers assessed the impact of OSA on functional prognosis in the acute phase of stroke, and reviewed quantitative electroencephalography (EEG) markers in stroke patients during sleep.

Overall, individuals with severe OSA were significantly more likely than those with less severe OSA to have comorbid hypertension (85.4% vs. 56%; P = .002) and a higher body mass index (28 vs. 24; P < .001). Other factors including blood pressure, smoking history, alcohol use, and comorbid diabetes were similar between the groups.

Quantitative EEG among patients with severe OSA showed lower relative power of high-frequency bands (alpha, beta, and sigma). The EEG also showed higher delta/alpha power ratio and slowing ratio, and higher delta relative power (delta RP) in severe OSA (P < .05 for all).

In addition, severe OSA was associated with more than triple the risk (3.6-fold increase) of poor prognosis, defined as a Modified Rankin Scale score of 3 or higher (24.4% for severe OSA vs. 8.3% for nonsevere OSA; P = .03).

“Our study confirmed that severe OSA is an independent risk factor for poor functional prognosis in the acute phase of ischemic stroke,” the researchers wrote. “Integrating the alteration of quantitative EEG parameters may improve the accuracy of early predictions of functional prognosis in patients with stroke.”

The findings were limited by several factors including the retrospective design and the lack of a sizable non-OSA control group, the researchers noted. Other limitations included the use of an AHI of 30/h or higher to define severity and the use of data from medical histories, with the potential for information bias, and the use of only 30-second continuous polysomnography segments.

However, the results suggest that increased delta RP and TSR, and decreased alpha, beta, and sigma RP, may be independent predictors of a poor functional prognosis in stroke patients with OSA, and that the prognosis could be improved by treating the OSA, they concluded.

The study was supported by the Natural Science Foundation of China and the Discipline Construction Program of the Second Affiliated Hospital of Soochow University. The researchers reported no financial conflicts.
