The Food and Drug Administration has approved an expanded heart failure indication for the sodium-glucose transporter 2 inhibitor empagliflozin (Jardiance) that now includes HF with mid-range or preserved left ventricular ejection fraction (LVEF), the agency announced on Feb. 24.

That means the SGLT2 inhibitor, once considered primarily an antidiabetic agent, is approved for use in patients with HF per se without regard to ventricular function. The drug received approval for HF with reduced LVEF in August 2021.

The expanded indication, specifically for reducing the risk of cardiovascular death and HF hospitalization in adults, was widely anticipated based on the landmark results from the EMPEROR-Preserved trial. The study saw a significant 21% relative reduction in that composite endpoint over about 2 years in patients with New York Heart Association class II-IV heart failure and an LVEF greater than 40% who received empagliflozin along with other standard care.

Interestingly, the drug’s expanded indication in HF resembles that approved for sacubitril/valsartan (Entresto) in February 2021 based mostly on the PARAGON-HF trial, which entered patients with HF and an LVEF at least 45%. The trial was “negative” in that it saw no significant advantage to the drug for its primary clinical outcome but did suggest benefit for some secondary endpoints.

The FDA had used more cautionary language in its expanded indication for sacubitril/valsartan, “to reduce the risk of cardiovascular death and hospitalization for heart failure in adult patients with chronic heart failure. Benefits are most clearly evident in patients with left ventricular ejection fraction below normal.”

New recommendations from the European Alliance of Associations for Rheumatology provide both broad and detailed advice for cardiovascular risk management in various rheumatic and musculoskeletal diseases (RMDs), many of which can lead to an increased possibility of cardiovascular disease (CVD).

“The panel believes that these recommendations will enable health care providers and patients to mutually engage in a long-term care pathway tailored to patients’ needs and expectations for improving cardiovascular health in RMDs,” write George C. Drosos, National and Kapodistrian University of Athens, and colleagues. The recommendations were published in February in Annals of the Rheumatic Diseases).

EULAR assembled a task force to generate best practices for preventing CVD in patients with gout, vasculitis, systemic sclerosis (SSc), myositis, mixed connective tissue disease (MCTD), Sjögren syndrome (SS), systemic lupus erythematosus (SLE), and antiphospholipid syndrome (APS).

The cardiovascular risk management of patients with rheumatoid arthritis, ankylosing spondylitis, and psoriatic arthritis was covered in prior EULAR recommendations.

The task force included 20 members from 11 European countries, including 12 rheumatologists, 2 cardiologists, 1 metabolic medicine physician, 1 health care professional, 2 patient representatives, and 2 EMEUNET (Emerging EULAR Network) members. One group of task force members conducted a systematic literature review of 105 articles about gout, vasculitis, SSc, myositis, MCTD, and SS, and another group evaluated 75 articles about SLE and APS. Together, they decided on four overarching principles:

Clinicians need to be aware of increased cardiovascular risk in patients with RMDs, with disease reduction likely decreasing risk.

Rheumatologists – in tandem with other health care providers – are responsible for their patients’ cardiovascular risk assessment and management.

Screening for cardiovascular risk should be performed regularly in all patients with RMDs, with an emphasis on factors like smoking and blood pressure management.

Patient education and counseling on cardiovascular risk, including important lifestyle modifications, is key for RMD patients.

Specific recommendations from the gout, vasculitis, SSc, myositis, MCTD, and SS group include deploying existing cardiovascular prediction tools as they are used in the general population, with the European Vasculitis Society model suggesting to supplement the Framingham Risk Score for patients with antineutrophil cytoplasmic antibody–associated vasculitis. They also recommended avoiding diuretics in patients with gout and beta-blockers in patients with SSc, as well as following the same blood pressure and lipid management strategies that are used among the general population.

Recommendations from the SLE and APS group include thoroughly assessing traditional cardiovascular risk factors in all patients, following typical blood pressure management strategies in patients with APS, and setting a blood pressure target of less than 130/80 mm Hg in patients with SLE. They also recommended administering the lowest possible glucocorticoid dose in patients with SLE, along with treatment with hydroxychloroquine – unless contraindicated – and even common preventive strategies like low-dose aspirin if it suits their cardiovascular risk profile.

As for next steps, the task force noted several areas where additional focus is needed, such as identifying patient subgroups with increased cardiovascular risk. This could include patients with a longer disease duration or more flare-ups, older patients, and those with certain disease characteristics like antiphospholipid positivity in SLE.

Can EULAR’s recommendations be implemented in U.S. rheumatology practices?

“We have been hearing for years that patients with rheumatic diseases have an increased risk of cardiovascular disease,” Ali A. Duarte Garcia, MD, a rheumatologist at the Mayo Clinic in Rochester, Minn., told this news organization. “That has been consistently published for more than a decade now. But any further guidance about it has not been issued. I think there was a void there.”

“Certainly, cardiovascular disease risk in rheumatoid and psoriatic arthritis has been front of mind for the last decade or so,” Christie M. Bartels, MD, chief of the division of rheumatology at the University of Wisconsin, Madison, said when asked to comment on the recommendations. “But in some of these other conditions, it hasn’t been.”

When asked if rheumatologists would be ready and willing to implement these recommendations, Dr. Duarte Garcia acknowledged that it could be challenging for some.

“It’s a different workflow,” he said. “You’ve been trained traditionally to assess inflammation, to keep the disease under control, which is something they recommend, by the way. If you control the disease, patients do better. But I think lipid screening, for example, and testing for cholesterol, smoking cessation, those well-established programs are harder to bring to a rheumatology clinic. It’s doable, but it’s something that needs to be implemented within the current workflows and could take a few years to take hold.”

Dr. Bartels, however, noted that her group has done extensive work over the last 5 years incorporating certain interventions into practice, including sending patients with high blood pressure back to primary care.

“It’s a sustainable intervention in our clinic that basically our medical assistants and nurses do as a routine operation,” she said. “Our primary care providers are grateful to get these patients back. Our patients are grateful because otherwise when they come to the rheumatologist, get their blood pressure measured, and don’t get feedback, they assume they’re OK. So, we’re giving them a false signal.

“We have a similar intervention with smoking,” she added. “Often our patients aren’t even aware that they’re at increased risk of cardiovascular disease or that smoking might make their rheumatic disease and their cardiovascular outcomes worse. No one has had that conversation with them. They really welcome engaging in those discussions.

“Our tobacco intervention takes 90 seconds at point of care. Our blood pressure intervention at point of care, we’ve timed it, takes 3 minutes. There are ways that we can hardwire this into care.”

Along those lines, Dr. Duarte Garcia stated that the recommendations – although released by EULAR – are largely intuitive and should be very adaptable to an American health care context. He also recognized this moment as an opportunity for rheumatologists to consider patient outcomes beyond what they usually encounter firsthand.

“I don’t think we have many rheumatologists with patients who get a stroke or heart attack because if that happens, it’s in a hospital context or they go see a cardiologist,” he said. “You may see it once it happens if they survive and come and see you – or perhaps if you’re in a more integrated practice – but I don’t think it’s as apparent in our clinics because it is a predominantly outpatient practice and many times those are emergencies or inpatient complications.

“The bottom line,” he added, “is these are practical guidelines. It’s a push in the right direction, but there is still work to be done. And hopefully some of the recommendations, like measuring high blood pressure and addressing it just as in the general population, are something we can start to implement.”

Dr. Duarte Garcia reported receiving grant funding from the Rheumatology Research Foundation and the Centers for Disease Control and Prevention. Dr. Bartels reported that her group’s tobacco cessation work is funded by Pfizer’s Independent Grants for Learning and Change.

Catholic Medical Center has agreed to pay $3.8 million to settle claims it provided free call coverage to a cardiologist in exchange for patient referrals to the Manchester, N.H., hospital, according to federal officials.

“The cardiologist who received the free call coverage referred millions of dollars in medical procedures and services to CMC over the decade in which the free services were provided,” the Department of Justice said in a news release.

Because the hospital submitted claims for payment to Medicare, Medicaid, and other federal health care programs for the services referred by the cardiologist, the government alleged the claims were the result of unlawful kickbacks.

The settlement resolves allegations brought in a whistleblower lawsuit filed in 2018 by cardiologist David Goldberg, MD, who previously worked at Catholic Medical Center (CMC) and is represented by Douglas, Leonard & Garvey.

The news release did not name the cardiologist involved in the alleged kickback scheme but the recently unsealed lawsuit says CMC paid its cardiologists above market rates ($10,000 per weekend, $3,000 per night) to provide free coverage services for Mary-Claire Paicopolis, MD.

The lawsuit also claims Dr. Paicopolis insisted the hospital implant only Boston Scientific devices in her patients and that her preferred electrophysiologist use only its Rhythmia mapping system during ablation procedures. To keep CMC from objecting, the suit alleges Boston Scientific offered CMC early access to its Watchman left atrial appendage occluder and provided “unprecedented” support to a nonacademic community hospital site.

“It went back several years, and that and the other issues in the suit were strong motivators for Dr. Goldberg to try to rectify the situation and he deserves a lot of credit for having done so,” attorney Charles G. Douglas III told this news organization.

Dr. Goldberg will receive $570,000 of the $3.8 million settlement as well as $145,361 in expenses, attorney fees, and costs.

Although not addressed in the federal news release, the lawsuit also alleges that CMC staff manipulated mortality data by discharging patients from the ICU and then readmitting them to hospice with a new patient number, “thereby avoiding the need to claim a surgical mortality.”

The lawsuit also says CMC “created a practice of covering up medical errors” and detailed 12 patient deaths between 2012 and 2018, alleging that these deaths were the result of substandard care.

CMC spokesperson Lauren Collins-Cline said in an email that the call coverage arrangement is no longer in place and originated almost 15 years ago with the input of legal counsel in order to provide high-quality care for patients.

“While CMC vigorously disagrees with the government’s allegations that this arrangement violated federal law, we have agreed to settle in order to avoid long costly civil litigation,” she said.

As to the other claims in the complaint, Ms. Collins-Cline said they were investigated by the government and dismissed per the settlement agreement. “CMC holds itself to the highest ethical standards in patient care and business conduct. That’s embedded in our mission and will always remain our highest priority.”

Mr. Douglas, however, said the government retains the right to pursue other claims in the lawsuit in the future. “So, [the hospital] is a little more optimistic than the reality of what the government agrees is the situation.”

Mr. Douglas, however, said the government retains the right to pursue other claims in the lawsuit in the future. “So, [the hospital] is a little more optimistic than the reality of what the government agrees is the situation.”

The Dexcom G7 continuous glucose monitor (CGM) is as accurate or better than other currently marketed CGM devices for measuring glucose in those with diabetes, new data from a pivotal study suggest.  

Currently under review by the U.S. Food and Drug Administration, the G7 is expected to be an improvement over the Dexcom G6 version in several ways.

The on-body size will be 60% smaller, “roughly the size of three stacked quarters,” according to the authors, and will incorporate the sensor with a single-use transmitter, as opposed to the current separate 3-month transmitter used with the G6 sensor. This will eliminate the need for using a transmitter across multiple sensor sessions (as is the case for G6).

The warm-up period after insertion is reduced from 2 hours to 27 minutes, and users are given an extra 12-hour “grace period” after the 10-day wear period to change the device before it stops displaying glucose data. Up to 24 hours of missed data can also be recaptured.

“The enhanced features of G7 may increase clinical adoption, encourage sustained use, and reduce the burden of diabetes management,” write Satish K. Garg, MD, of the University of Colorado, Aurora, and colleagues, in their article, published online Feb. 14 in Diabetes Technology & Therapeutics.  

Several features of the G6 remain unchanged, including factory calibration, but also the capacity for optional user calibrations, use of Bluetooth to transmit data up to 20 feet (approximately 6 meters), and data displays on either a dedicated receiver or a variety of iOS and Android smart devices.

It will also allow for user-customized settings and alerts, as well as the option for real-time remote “share” monitoring with caregivers or providers. The G7 will also not be susceptible to interference by acetaminophen (paracetamol) or ascorbic acid.

And, like the G6, the G7 was submitted for approval to the FDA as an “integrated CGM,” meaning that it will be interoperable with other compatible devices, including insulin pumps, glucose meters, or other electronic devices used for diabetes management.

Accuracy shown on abdomen, arm

The prospective, multicenter, single-arm study reported by Dr. Garg and colleagues was conducted at 12 U.S. sites between February and June 2021.

In-clinic visits were conducted on days 1 or 2, 4 or 7, and one additional day for comparisons with a reference glucose measure (YSI 2300 Stat Plus glucose analyzer). Participants wore blinded G7 sensors concurrently on the upper arm and abdomen while continuing to use their own personal glucose monitoring method (CGM or fingerstick) at home.

A total of 316 insulin-using adults with type 1 or type 2 diabetes contributed data from 308 arm- and 311 abdomen-placed blinded devices, which generated 77,774 matched pairs of data within the blood glucose reportable range of 40-400 mg/dL.  

The overall mean absolute relative difference (MARD) of each CGM-YSI pair (a standard metric for CGM analysis) was 8.2%, with 9.1% for the abdomen and 8.2% for the arm.

Accuracy remained high in both arm- and abdomen-placed sensors across the 10-day wear period through the 12-hour grace period and across glucose ranges. There were no significant differences between G7 accuracy by diabetes type, insulin regimen, or body mass index.

The highest agreement rates and lowest MARDs occurred when CGM readings were increasing or decreasing by no more than 1 mg/dL per minute. However, even at the highest rates of glucose concentration change, MARD values below 10% were found for arm-placed sensors and below 10.5% for abdomen-placed sensors, Dr. Garg and colleagues report.

When the hypoglycemia threshold alert was set to 55 mg/dL, true alert rates for detection of hypoglycemia below 70 mg/dL by sensors worn on the arm and abdomen were 91.3% and 85.2%, respectively. With hyperglycemia threshold alerts set to 300 mg/dL, the true alert rates for detection of hyperglycemia greater than 250 mg/dL by sensors worn on the arm and abdomen were 99.9% and 99.8% respectively.

The overall mean time lag for the sensors was 3.5 minutes, 3.6 minutes for the arm, and 3.4 minutes for the abdomen. There were no serious adverse events during the study.

The study excluded children and adolescents; data from these populations will be reported separately, the authors note.
 

Accuracy at least as good as prior Dexcom versions, competitors

The MARD values of 8.2% on the arm and 9.1% on the abdomen were similar to or better than accuracy measurements of other commercially available CGM systems, note Dr. Garg and colleagues, although they acknowledge that few head-to-head studies at different anatomic locations have been conducted.

A study of an older Dexcom version (G4 Platinum) found MARD estimates of 12.0% on the arm and 12.3% on the abdomen, the authors note.  

The newly FDA-approved implantable Eversense E3 (Senseonics) CGM, worn on the upper arm, has a MARD of 9.1%, while the arm-placed Abbott FreeStyle Libre 2, approved in the U.S. in June 2020, has an overall MARD of 9.3%.

Lag-time differences between the reference and G7 were also similar to or better than time delays in prior-generation Dexcom CGMs, Dr. Garg and colleagues say.

Participants also completed a survey. “The redesigned applicator allows for sensor deployment with one hand, and most participants found G7 easier to insert than their prior CGM system,” the researchers say.

Finally, “unlike G6, G7 allows for temporary silencing of all audible alerts, including Urgent Low. Taken together, these attributes are anticipated to provide for a better end-user experience with G7 and help reduce diabetes burden,” they conclude.

The study was supported by a grant from Dexcom. Dr. Garg has reported receiving consultant fees from Medtronic, Novo Nordisk, Zealand, LifeScan, Roche, and Lilly, as well as research grants through the University of Colorado from Lilly, Novo Nordisk, Medtronic, Dexcom, T1D Exchange, Helmsley Trust, NIDDK, and JDRF.

Eating sufficient amounts of vegetables might be good for overall health, but surprising results from a study suggested that their inclusion in the diet might have little or no effect on the risk of developing cardiovascular disease (CVD).

An investigation, led by the Nuffield department of population health at the University of Oxford, found that cooked vegetables did not appear to lower CVD risk, and that a small decrease associated with eating raw vegetables could be attributed to confounding factors. They said their findings, published in the journal Frontiers in Nutrition might mean that advice on vegetable intake and heart disease in high-income countries should be reappraised.

Teresa Burton/MDedge News

However, leading experts commented that the findings confirmed that higher overall vegetable consumption did lower the risk of cardiovascular disease.
 

UK Biobank data

Boosting health through a diet rich in vegetables has been backed by a large body of evidence, with guidelines consistently recommending them as a valuable source of macronutrients and micronutrients, such as dietary fiber, vitamins, and phytochemicals. However, the research team, which included the Chinese University of Hong Kong and the University of Bristol, set out to probe the independent effects of cooked and raw vegetables on health outcomes. Previous epidemiological studies had demonstrated inconsistent findings, they said.

They based their research on 399,586 people with no history of angina, stroke, and myocardial infarction, who enrolled in the UK Biobank. Of those, 55.4% were women, and 90.9% were of White ethnicity. The average body mass index was 27.3.
 

Raw and cooked vegetables

From their enrollment questionnaire, the mean intake of vegetables was found to be 2.3 heaped tablespoons per day of raw vegetables, and 2.8 of cooked vegetables. During an average follow-up of 12.1 years, 4.5% of the participants went on to develop CVD.

There was an inverse association between incident CVD and total and raw vegetable intake, but not cooked vegetable intake. Those who ate the most vegetables – both cooked and raw – had a 10% lower incidence of CVD, compared with those who ate the least. However, whereas raw vegetable intake was associated with an 11% reduction in CVD for those who ate the most, compared with the least, no reduction was seen for cooked vegetables.

Consuming two or more heaped tablespoons each day of cooked and raw vegetables was associated with a lower risk of dying from CVD, but little evidence was seen that a higher intake increased protection further. Similarly, there was evidence of an inverse association of CVD mortality with raw vegetable intake.

Researcher Qi Feng, from the Nuffield department of population health, said: “Our large study did not find evidence for a protective effect of vegetable intake on the occurrence of CVD. Instead, our analyses show that the seemingly protective effect of vegetable intake against CVD risk is very likely to be accounted for by bias from residual confounding factors, related to differences in socioeconomic situation and lifestyle.”

Expert opinions

Some clinical specialists took issue with the interpretation of the findings.

Dr. Dipender Gill, BMBCh, PhD, National Institute for Health Research clinical lecturer at St George’s, University of London, told the Science Media Centre that: “Many of the considered confounders that were adjusted for may actually represent mediating mechanisms.  For example, vegetable consumption may reduce cardiovascular risk by lowering blood pressure and bodyweight, and improving glycaemic control. 

“By adjusting for such traits, the authors may inadvertently be negating some of the mechanisms by which vegetable consumption is exerting beneficial effects.”

Tom Sanders, DSc, PhD, professor emeritus of nutrition and dietetics at King’s College London, said: “The conclusion that cooked vegetables may not be effective in reducing risk of cardiovascular disease may not be justified, especially as the group consuming the highest levels of vegetables were more likely to be receiving medication for high blood cholesterol and high blood pressure (i.e. this group was at higher risk of CVD), compared with those consuming the lowest intake.” He added: “These findings should not be taken to indicate that eating more vegetables has no benefit to health, especially cardiovascular health.”

Naveed Sattar, FMedSci, FRCPath, FRCPGlas, professor of metabolic medicine at the University of Glasgow, agreed. “In short, this paper should in no way change advice to eat at least five portions of fruit and vegetables a day,” he said. “Many living in the U.K. fall well short of this, sadly, and more needs to be done to encourage better intake of vegetables.

“In fact, I suspect we may have underestimated the importance of a healthy diet on health and disease in general.”

As COVID-19 cases and hospitalizations continue to decline across the United States, all states but one -- Hawaii -- have dropped their mask mandates or have announced plans to do so in coming weeks.

Retailers and cruises are following along, with Apple and Target stores lifting their own mask mandates this week. Cruise lines such as Norwegian and Royal Caribbean International have said mask requirements will be relaxed for vaccinated passengers, according to the Washington Post.

But guidance from the Centers for Disease Control and Prevention hasn’t changed even as the Omicron variant recedes across the country. Vaccinated people should wear masks when indoors in areas of “substantial or high transmission,” which still covers more than 95% of the country, according to a CDC map.

As daily cases continue to fall, the CDC is reviewing its recommendations, Rochelle Walensky, MD, the CDC director, said during a briefing last week.

“We want to give people a break from things like mask-wearing, when these metrics are better, and then have the ability to reach for them again should things worsen,” she said.

As states relax mask rules, county and city officials are now deciding what to do in their jurisdictions. Vaccinated residents in Los Angeles County may soon be able to go maskless in indoor settings that check for proof of vaccination, according to the Los Angeles Times.

Chicago will also end its mask and COVID-19 vaccine mandates for public places such as restaurants Feb. 28, according to the Chicago Tribune. Illinois will end a statewide indoor mask mandate on the same day. Masks will still be required in health care settings and public transmit.

State and local school boards are debating their mask policies as well. The Maryland State Board of Education voted Feb. 22 to allow local school districts to decide whether students must wear face coverings in school, according to the Associated Press. The update will take effect on March 1 if approved by a Maryland General Assembly committee that oversees the rule.

In New York, state officials have begun lifting mask rules. At the same time, 58% of New York voters want to see early March data before school mask mandates are ended, according to a new poll, released Feb. 22 by the Siena College Research Institute. About 45% of those polled said the state’s indoor public mask mandate should also still be in place.

The debate about wearing masks in schools will likely continue, especially as districts get caught between health authorities and parents, according to the Wall Street Journal. District officials in several states are receiving hundreds of emails daily from both sides, with parents calling for mask rules to end or saying that requirements should remain in place for now to keep kids safe.

As COVID-19 cases and hospitalizations continue to decline across the United States, all states but one -- Hawaii -- have dropped their mask mandates or have announced plans to do so in coming weeks.

Retailers and cruises are following along, with Apple and Target stores lifting their own mask mandates this week. Cruise lines such as Norwegian and Royal Caribbean International have said mask requirements will be relaxed for vaccinated passengers, according to the Washington Post.

But guidance from the Centers for Disease Control and Prevention hasn’t changed even as the Omicron variant recedes across the country. Vaccinated people should wear masks when indoors in areas of “substantial or high transmission,” which still covers more than 95% of the country, according to a CDC map.

As daily cases continue to fall, the CDC is reviewing its recommendations, Rochelle Walensky, MD, the CDC director, said during a briefing last week.

“We want to give people a break from things like mask-wearing, when these metrics are better, and then have the ability to reach for them again should things worsen,” she said.

As states relax mask rules, county and city officials are now deciding what to do in their jurisdictions. Vaccinated residents in Los Angeles County may soon be able to go maskless in indoor settings that check for proof of vaccination, according to the Los Angeles Times.

Chicago will also end its mask and COVID-19 vaccine mandates for public places such as restaurants Feb. 28, according to the Chicago Tribune. Illinois will end a statewide indoor mask mandate on the same day. Masks will still be required in health care settings and public transmit.

State and local school boards are debating their mask policies as well. The Maryland State Board of Education voted Feb. 22 to allow local school districts to decide whether students must wear face coverings in school, according to the Associated Press. The update will take effect on March 1 if approved by a Maryland General Assembly committee that oversees the rule.

American health care workers have remained resilient during the pandemic but are feeling the ongoing strain, with 23% saying they are likely to leave the field in the near future, according to a new poll.

About half of the respondents to the poll from USA Today/Ipsos reported feeling “burned out,” 43% said they were “anxious,” and 21% said they were “angry” about politics and abuse from patients and families.

“We’re trying to help people here, and we are getting verbally and physically abused for it,” Sarah Fried, a nurse in California who responded to the survey, told USA Today in a follow-up interview.

“Early in this pandemic, people were clapping for us and calling us heroes,” she said. “And what happened to that? What happened to them appreciating what nurses are doing?”

The poll was done Feb. 9-16 among 1,170 adults in the U.S. health care industry, including doctors, nurses, paramedics, therapists, home health aides, dentists, and other medical professionals.

A large majority of workers still reported being satisfied with their jobs, although that optimism has declined somewhat since early 2021 when the COVID-19 vaccine rollout was underway. About 80% of those in the recent poll said they were somewhat or very satisfied with their current job, which is down from 89% in an April 2021 poll from Kaiser Family Foundation/the Washington Post.

Most health care workers reported feeling “hopeful” (59%), “motivated” (59%), or “optimistic” (56%) about going to work. But “hopeful” is down from 76% and “optimistic” is down from 67%, compared with last year.

If they could pick a career over again, about 16% disagreed with the statement, “I would still decide to go into health care,” and 18% said they didn’t know how they felt about it.

“The pandemic has actually made me realize how important this career is and how I really do make a difference. I still love it,” Christina Rosa, a mental health counselor in Massachusetts, told USA Today.

During the pandemic, about 66% of those polled said they had treated a COVID-19 patient, which increased to 84% among nurses and 86% among hospital workers. Among those, 47% reported having a patient who died from COVID-19, including 53% of nurses and 55% of hospital workers.

What’s more, 81% of those who treated COVID-19 patients have cared for unvaccinated patients. Among those, 67% said their patients continued to express skepticism toward COVID-19 vaccines, and 38% said some patients expressed regret for not getting a vaccine. Beyond that, 26% said unvaccinated patients asked for unproven treatments, and 30% said the patient or family criticized the care they received.

Regarding coronavirus-related policy, most Americans working in health care expressed skepticism or criticism of the nation’s handling of the pandemic. About 39% agreed that the American health care system is “on the verge of collapse.”

Only 21% said the pandemic is mostly or completely under control. About 61% don’t think Americans are taking enough precautions to prevent the spread of the coronavirus.

Health care workers were slightly positive when it comes to the Centers for Disease Control and Prevention (54% approve, 34% disapprove), divided on the Biden administration (41% approve, 40% disapprove), and critical of the news media (20% approve, 61% disapprove) and the American public (18% approve, 68% disapprove).

Broadly, though, health care workers support public health efforts. About 85% back measures that provide N95 masks, and 83% back measures that provide COVID-19 tests.

Big Vegetable has lied to us all

Hear this, children of the world: Your parents have betrayed you. They tell you day in and day out that vegetables are necessary, that they’re healthy, that you need them, but it is not the truth. Behind their foul taste is nothing but empty lies.

Okay, before we get a full-blown child rebellion on our hands, let’s reel things in. Eating vegetables has many benefits, and will help prevent many nasty medical conditions, such as diabetes or cancer. However, cardiovascular disease is not among them.

nneem/Pixabay

For their study published in Frontiers in Nutrition, researchers analyzed the diet, lifestyle, and medical history of nearly 400,000 U.K. adults over a 5-year period, finding that 4.5% developed heart disease and that the average adult consumed about 5 tablespoons of vegetables per day. Those who consumed the most vegetables had a reduction in heart disease incidence of about 15%, compared with those who ate the least.

Hang on, you’re thinking, we just said that vegetables didn’t prevent cardiovascular disease. But the data show otherwise! Ah, but the data are unadjusted. Once the researchers took socioeconomic status, information level, and general lifestyle into account, that benefit disappeared almost completely. The benefit seems to come not from the vegetables themselves, but from being able to afford better food and medical care in general.

The researchers were quick to note the other benefits of eating vegetables, and that people should probably keep eating those five servings a day. But we’re onto you, scientists. You can’t fool us with your vegetable-based lies. Unless we’re talking about pizza. Pizza is the best vegetable.
 

The good old days of surgery?

Modern surgical instruments, techniques, and technological innovations are amazing. It’s hard to imagine what surgery was like before laparoscopes came along, or x-ray machines, or even anesthesia. But those days weren’t really that long ago. Modern anesthesia, after all, dates back to just 1846. We’ve got socks almost that old.

But suppose we go back even further … say 5,300 years. Older than the oldest sock. Scientists studying a funerary chamber in Burgos, Spain, which was built in the 4th millennium B.C., have come across what looks like “the first known radical mastoidectomy in the history of humankind,” Sonia Díaz-Navarro of the University of Valladolid (Spain) and associates wrote in Scientific Reports.

One of the skulls they uncovered shows signs of trepanation. “Despite the [evidence] of cut marks, it is difficult to conclude the type of tool used to remove the bone tissue, most likely a sharp instrument with a circular movement,” they investigators said.

What is clear, though, is that the patient survived the surgery, because there is evidence of bone regeneration at the surgical sites. Sites? “Based on the differences in bone remodelling between the two temporals, it appears that the procedure was first conducted on the right ear, due to an ear pathology sufficiently alarming to require an intervention, which this prehistoric woman survived,” they explained.

The same procedure was then performed on the left ear, “but whether this was performed shortly after the right ear, or several months or even years later can’t be concluded from the existing evidence,” IFL Science reported.

Located nearby was a small section of tree bark with some scratches on it. That, ladies and gentlemen, was the first prior authorization form.
 

I hate that song, with reason

Do you have a favorite song? You may have a million reasons for loving that song. And past research can tell you why. But it’s only in a recent study that researchers were able to tell you why you dislike a song. And you know the song we’re talking about.

MPI for Empirical Aesthetics

Dislike breaks down into three major categories of rationale: subject-related reasons (how the song makes you feel emotionally and/or physically), object-related reasons (the lyrics or composition), and social reasons (do you relate to this?). Researchers at the Max Planck Institute for Empirical Aesthetics in Frankfurt, Germany, interviewed 21 participants and asked them to come up with a prepared list of music that they disliked and why they didn’t like it. And there was a lot that they didn’t like: 277 dislikes worth, to be exact.

“The most often mentioned type of dislike was musical style, followed by artist and genre,” senior author Julia Merrill explained on Eurekalert. Just over 40% of those rationales for not liking the music just had to do with the music itself, but 85% involved the music combined with one of the other categories.

Social reasoning played a big part in dislike. If the listener didn’t feel like a part of the target in-group for the music or the music didn’t have the same social values as those of the listener, it had an impact on dislike, they said.

But our dislike of certain types of music doesn’t just separate us from people in a negative way. Looking at the dislike of certain types of music helps us define our terms of having good taste, the researchers explained. Saying that one type of music is better than another can bring us closer with like-minded people and becomes a piece of how we identify ourselves. Cue the music snobs.

So if you can blast Barry Manilow but can’t bring yourself to play the Rolling Stones, there’s a reason for that. And if you love Aretha Franklin but not Frank Sinatra, there’s a reason for that, too. It’s all very personal. Just as music is meant to be.

The use of a robotic-assisted device to perform transcranial Doppler ultrasound greatly improved the detection of right-to-left cardiac shunts in patients with presumed embolic strokes compared with the current standard of care – transthoracic echocardiography – in a new study.

Being far easier to perform than regular transcranial Doppler ultrasound, it’s hoped that use of the robotic device will enable many more patients to undergo the more sensitive transcranial screening modality and increase the number of shunts identified.

“I believe robot-assisted transcranial Doppler ultrasound can fill the gap between the gold standard transcranial Doppler and transthoracic echocardiography, which is the current standard of care,” said lead author Mark Rubin, MD.  

Dr. Rubin, who is assistant professor of neurology at University of Tennessee Health Science Center, Memphis, presented results of the BUBL study at the International Stroke Conference (ISC) 2022, where they were greeted with applause from the floor.
 

An improvement in the current standard of care

Dr. Rubin explained that patients with suspected embolic stroke are routinely screened for shunts in the heart, such as patent foramen ovale (PFO), that allow blood to flow from the right chamber to the left chamber and can lead to clots from the venous system, accessing the arterial system, then traveling to the brain and causing a stroke.

The current standard of care in screening for such shunts is the use of transthoracic echocardiography (TTE), a widely available and easy to perform, non-invasive procedure. “But we have known for decades that TTE does not pick up these shunts very well. With a sensitivity of only around 45%, it identifies less than half of the patients affected,” Dr. Rubin noted.  

The more sensitive transesophageal echocardiography (TEE) gives much better results, but it is an invasive and unpleasant procedure with the ultrasound probe being passed down the throat, and the patient needing to be sedated, so it’s not appropriate for everyone, he noted.

“Transcranial Doppler ultrasound (TCD) also gives excellent results, with a sensitivity of about 96% for detecting PFO, but this procedure is difficult to perform and requires a great deal of skill in placing the probes in the right position and interpreting the signal,” Dr. Rubin said. “TCD has been around for decades, but it hasn’t caught on, as it is too difficult to do. It takes a lot of time to learn the technique.”

“With the robotic-assisted transcranial Doppler device, we can achieve the sensitivity of TCD without needing expert operators. This should vastly improve accessibility to this technology,” he said. “With such technology we can make significant strides into more accurate diagnoses on the cause of stroke, which should lead to better preventive treatments in those found to have right-to-left shunts.”  
 

Robotic detection of shunts

For the BUBL study, the robotic TCD technique was compared with the standard TTE in 129 patients who had a diagnosis of presumed embolic stroke or transient ischemic attack (TIA), with all patients undergoing both procedures.  

The robotic TCD device resembles a giant pair of headphones containing the ultrasound probes, which are attached to a frame. In the study, it was operated by a health care professional without TCD skills. Each ultrasound probe independently scans the temporal area autonomously – with angling and positive pressure against the scalp akin to a sonographer – to find and optimize bilateral middle cerebral artery signals, Dr. Rubin explained.

The primary endpoint was the detection of a right-to-left shunt. This occurred in 82 of the 129 patients (63.6%) with the robotic TCD device but in only 27 patients (20.9%) when TTE was used. This gives an absolute difference of 42.6% (95% confidence interval, 28.6%-56.7%; P < .001), which Dr. Rubin described as “astounding.”

However, he said he was not surprised by these results.

“In my experience with transcranial Doppler, I find shunts in patients every day that have not been seen with transthoracic echo,” he commented.

He noted that a previous meta-analysis has suggested a similar difference between TCD and transthoracic echo, but the current study provides prospectively collected data produced in a clinical trial setting and is therefore more reliable. 

“What I hope comes from this is that more patients will be able to undergo transcranial Doppler, which is a far superior screening technique for identifying right-to-left shunts. There is so much evidence to support the use of transcranial Doppler, but with this new artificial-intelligence robotic device, we don’t need an expert to use it,” Dr. Rubin said.   

He explained that finding a right-to-left shunt in stroke patients is particularly important, as it can direct treatment strategies to reduce future risk of recurrent strokes.

“If a patient has a large shunt, then they have a high risk of having another stroke, and the PFO should be closed.”

In this study, the robotic-assisted TCD detected three times as many large shunts that were considered “intervenable,” compared with transthoracic echo, identifying these shunts in 35 patients (27%) compared to just 13 (10%) with TTE.

“Of the 35 patients with intervenable shunts detected with robotic transcranial Doppler, TTE was completely negative in 18 of them and only suggested a small shunt in the others. So, the standard of care (TTE) missed half the patients with intervenable PFOs,” Dr. Rubin reported.
 

Study should ‘dramatically change’ practice

Commenting on the study, Patrick Lyden, MD, professor of physiology and neuroscience and of neurology, University of Southern California, Los Angeles, said: “Most clinicians hesitate to use transcranial Doppler given the need for specialized technical expertise to obtain a reliable result. This study showed that a robotic transcranial Doppler device – which can be applied by any cardiac non-invasive lab technician – provides reliable and rigorous data.”

He added: “This result will dramatically change the typical evaluation of patients with suspected PFO: In place of an invasive transesophageal echo that requires anesthesia and a cardiologist, most patients can have a non-invasive, robotic-guided transcranial Doppler and get the same diagnostic benefit.”

Dr. Lyden also pointed out that the cost of TCD is typically one-tenth that of TEE, although he said the cost of the robotic guided TCD “is not clear.”

A representative of the company that makes the robotic assisted device, NovaSignal, says the cost of the equipment is approximately $250,000, but “understanding the importance of the technology, we work with each hospital to meet their unique needs.”

The company adds that it currently has “over 45 commercial solutions deployed across 25 centers with 3-4 times growth expected year over year.”

The study was supported by NovaSignal, the company which makes the robotic device. Dr. Rubin reports acting as a consultant for the NovaSignal.

The use of a robotic-assisted device to perform transcranial Doppler ultrasound greatly improved the detection of right-to-left cardiac shunts in patients with presumed embolic strokes compared with the current standard of care – transthoracic echocardiography – in a new study.

Being far easier to perform than regular transcranial Doppler ultrasound, it’s hoped that use of the robotic device will enable many more patients to undergo the more sensitive transcranial screening modality and increase the number of shunts identified.

“I believe robot-assisted transcranial Doppler ultrasound can fill the gap between the gold standard transcranial Doppler and transthoracic echocardiography, which is the current standard of care,” said lead author Mark Rubin, MD.  

Dr. Rubin, who is assistant professor of neurology at University of Tennessee Health Science Center, Memphis, presented results of the BUBL study at the International Stroke Conference (ISC) 2022, where they were greeted with applause from the floor.

Given the expansive contemporary role of statins for primary cardiovascular disease (CVD) prevention, the language in the new U.S. Preventive Services Task Force draft guidance on their use in that setting may seem conservative. Even so, the proposed recommendations, open to public comment until March 21, take more recent data into account but don’t substantially vary from the 2016 USPSTF document they are intended to replace.

The task force concluded “with moderate certainty” that a statin prescription will clinically benefit adults aged 40-75 years without CVD but with at least one of several risk factors, such as dyslipidemia or diabetes, who have a 10-year CVD risk of at least 7.5%.

The net benefit of statin therapy is “at least small” for individuals in whom the 10-year CVD risk is 7.5% up to 10.0%, the new report states. That, says an accompanying USPSTF press release, means such people “may benefit from statin use and should decide with their clinician if taking a statin is right for them.”

Also, notes the report, the net benefit of statin therapy is “at least moderate” for individuals with a 10% or greater CVD risk over the next decade who, the press release states, “should take a statin to prevent a first heart attack or stroke.”

The evidence review on which the task force based the guidance, the report says, lacked sufficient basis for determining statin benefit versus risk in adults older than 75 years without a history of CVD. “In the absence of this evidence, clinicians should use their judgment as to whether to offer a statin to a patient in this age group,” according to the press release.

The review focused on 22 clinical trials for data on the statin benefits and saw significantly decreased associated risks for death from any cause, fatal or nonfatal stroke, and fatal or nonfatal myocardial infarction with treatment. The combined trial populations exceeded 85,000 for assessing all-cause mortality and 76,000 for each of the other two endpoints.

To assess any potential statin therapy harms, the evidence review covered 19 clinical trials with a combined enrollment of about 75,000 – two more trials than considered in the 2016 document – plus three observational studies with more than 400,000 participants. Statins were found not to be associated with an increased risk for study withdrawal because of adverse events, nor were there signs of greater risk for myalgia or new-onset diabetes, compared with placebo.

“A majority of the trials reviewed by the USPSTF used moderate-intensity statin therapy,” the report states. “Based on available evidence, use of moderate-intensity statin therapy seems reasonable for the primary prevention of CVD in most persons.”
