An online survey captured mixed information about people’s willingness to undergo surgery during a viral pandemic in relation to the vaccine status of the patient and staff. The findings showcase opportunities for public education and “skillful messaging,” researchers report.

In survey scenarios that asked people to imagine their vaccination status, people were more willing to undergo surgery if it was lifesaving, rather than elective, especially if vaccinated. The prospect of no hospital stay tipped the scales further toward surgery. The vaccination status of hospital staff played only a minor role in decision making, according to the study, which was published in Vaccine.

But as a post hoc analysis revealed, it was participants who were not vaccinated against COVID-19 in real life who were more willing to undergo surgery, compared with those who had one or two shots.

In either case, too many people were unwilling to undergo lifesaving surgery, even though the risk of hospital-acquired COVID-19 is low. “Making this choice for an actual health problem would result in an unacceptably high rate of potential morbidity attributable to pandemic-related fears, the authors wrote.

In an unusual approach, the researchers used Amazon’s Mechanical Turk to electronically recruit 2,006 adults. The participants answered a 26-item survey about a hypothetical surgery in an unnamed pandemic with different combinations of vaccine status for patient and staff.

Coauthor and anesthesiologist Keith J. Ruskin, MD, of the University of Chicago, told this news organization that they “wanted to make this timeless” and independent of COVID “so that when the next thing came about, the paper would still be relevant.”

The researchers were surprised by the findings at the extreme ends of attitudes toward surgery. Some were still willing to have elective surgery with (hypothetically) unvaccinated patients and staff.

“And people at the other end, even though they are vaccinated, the hospital staff is vaccinated, and the surgery is lifesaving, they absolutely won’t have surgery,” Dr. Ruskin said.

He viewed these two groups as opportunities for education. “You can present information in the most positive light to get them to do the right thing with what’s best for themselves,” he said.

As an example, Dr. Ruskin pointed to an ad in Illinois. “It’s not only people saying I’m getting vaccinated for myself and my family, but there are people who said I got vaccinated and I still got COVID, but it could have been much worse. Please, if you’re on the fence, just get vaccinated,” he said.

Coauthor Anna Clebone Ruskin, MD, an anesthesiologist at the University of Chicago, said, “Humans are programmed to see things in extremes. With surgery, people tend to think of surgery as a monolith – surgery is all good, or surgery is all bad, where there is a huge in between. So we saw those extremes. ... Seeing that dichotomy with people on either end was pretty surprising.

“Getting surgery is not always good. Getting surgery is not always bad. It’s a risk-versus-benefit analysis and educating the public to consider the risks and benefits of medical decisions, in general, would be enormously beneficial,” she said.

A post hoc analysis found that “participants who were not actually vaccinated against COVID-19 were generally more willing to undergo surgery compared to those who had one vaccination or two vaccinations,” the authors wrote.

In a second post hoc finding, participants who reported high wariness of vaccines were generally more likely to be willing to undergo surgery. Notably, 15% of participants “were unwilling to undergo lifesaving surgery during a pandemic even when they and the health care staff were vaccinated,” the authors wrote.

Dr. Keith J. Ruskin hypothesized about this result, saying, “What we think is that potentially actually getting vaccinated against COVID-19 may indicate that you have a lower risk tolerance. So you may be less likely to do anything you perceive to be risky if you’re vaccinated against COVID-19.”

The authors stated that “the risk of hospital-acquired COVID-19 even prior to vaccination is vanishingly small.” The risk of nosocomial COVID varies among different studies. An EPIC-based study between April 2020 and October 2021 found the risk to be 1.8%; EPIC describes the fears of a patient catching COVID at a hospital as “likely unfounded.”

In the United Kingdom, the risk was as high as 24% earlier in the pandemic and then declined to approximately 5% a year ago. Omicron also brought more infections. Rates varied significantly among hospitals – and, notably, the risk of death from a nosocomial COVID infection was 21% in April-September 2020.

Emily Landon, MD, an epidemiologist and executive medical director for infection prevention and control at the University of Chicago Medicine, told this news organization that the study’s data were collected during Delta, a “time when we thought that this was a pandemic of the unvaccinated. But there was serious politicization of the vaccine.”

Dr. Landon said one of the study’s strengths was the large number of participants. A limitation was, “You’re going to have less participants who are generally poor and indigent, and fewer old participants, probably because they’re less likely to respond to an online survey.

“But the most interesting results are that people who were wary of vaccines or who hadn’t been vaccinated, were much more willing to undergo surgical procedures in the time of a pandemic, regardless of status, which reflects the fact that not being vaccinated correlates with not worrying much about COVID. Vaccinated individuals had a lot more wariness about undergoing surgical procedures during a pandemic.”

It appeared “individuals who were vaccinated in real life [were] worried about staff vaccination,” Dr. Landon noted. She concluded, “I think it supports the need for mandatory vaccinations in health care workers.”

The study has implications for hospital vaccination policies and practices. In Cumberland, Md., when COVID was high and vaccines first became available, the Maryland Hospital Association said that all health care staff should be vaccinated. The local hospital, UPMC–Western Maryland Hospital, refused.

Two months later, the local news reporter, Teresa McMinn, wrote, “While Maryland’s largest hospital systems have ‘led by example by mandating vaccines for all of their hospital staff,’ other facilities – including UPMC Western Maryland and Garrett Regional Medical Center – have taken no such action even though it’s been 8 months since vaccines were made available to health care workers.”

The hospital would not tell patients whether staff were vaccinated, either. An ongoing concern for members of the community is the lack of communication with UPMC, which erodes trust in the health system – the only hospital available in this rural community.

This vaccine study supports that the vaccination status of the staff may influence some patients’ decision on whether to have surgery.

The Ruskins and Dr. Landon have disclosed no relevant financial relationships.

A Los Angeles County internist will pay nearly $9.5 million to resolve accusations that he submitted false claims to Medicare and California’s Medicaid program.

Part of the payment was a settlement in a civil case in which Minas Kochumian, MD, an internist who ran a solo practice in Northridge, Calif., was accused of submitting claims to Medicare and Medi-Cal for procedures, services, and tests that were never performed. The procedures he falsely billed for included injecting a medication for treating osteoarthritis and osteoporosis, draining tailbone cysts, and removal of various growths.

As part of the settlement, Dr. Kochumian admitted that he intentionally submitted false claims with the intent to deceive the United States and the State of California. The damages and penalties were possible under the federal False Claims Act and the California False Claims Act.

According to the Medical Board of California, Dr. Kochumian’s license is current and set to expire next July.

The allegations against Dr. Kochumian were first brought to the attention of authorities in a whistleblower lawsuit filed by Elize Oganesyan, Dr. Kochumian’s former medical assistant, and Damon Davies, former information technology consultant for the practice. Among her other duties, Ms. Oganesyan was responsible for verifying insurance eligibility and obtaining authorization for drugs, procedures, services, and tests.

The medical assistant first realized that something was amiss when a patient brought her a Medicare Explanation of Benefits document that included charges for an injection the practice had not administered, according to court records. Ms. Oganesyan then realized the clinic was filing claims for other services that were never provided. She stated in the original complaint that the clinic did not even have the necessary equipment for providing some of these tests — skin allergy tests, for example.  

The False Claims Act permits private parties to sue on behalf of the government for false claims for government funds and to receive a share of any recovery. Ms. Oganesyan and Davies will receive more than $1.75 million as their share of the recovery. The whistleblowers’ claims for attorneys’ fees are not resolved by this settlement, according to a statement from the U.S. Attorney’s Office, Eastern District of California.

The $9.5 million payment includes $5.4 million owed by Dr. Kochumian as criminal restitution following his guilty plea to one count of healthcare fraud in a separate criminal case filed in the Central District of California. In addition to the fine, Dr. Kochumian was sentenced to 41 months in prison, according to a statement by California Attorney General Rob Bonta.

“When doctors misuse the state’s Medi-Cal funds, they violate their Hippocratic Oath by harming a program which exists to help California’s Medi-Cal population, including the elderly, the sick, and the vulnerable,” said Mr. Bonta. “Dr. Kochumian’s alleged misconduct violated the trust of the patients in his care, and he selfishly pocketed funds that would otherwise have gone toward critical publicly funded healthcare services.”

The American Gastroenterological Association has published eight position statements aimed at reducing the burden of colorectal cancer (CRC).

The evidence-based statements, published in Gastroenterology, call for a national approach to CRC screening, outline the elements of a high-quality screening program, and make clear that payers should cover all costs, from bowel prep through pathology, plus follow-up for high-risk patients.

“There is strong evidence that CRC screening is effective [at reducing CRC incidence and mortality] ... but less than 70% of eligible individuals have been screened,” wrote authors led by David Lieberman, MD, who is on the AGA Executive Committee on the Screening Continuum and affiliated with Oregon Health and Science University, Portland, noting the recent expansion of eligibility to include individuals in the 45- to 49-year age group.

“CRC screening saves lives, but only if people get screened,” Dr. Lieberman said in a press release from the AGA. “Cost sharing is an important barrier to screening, which contributes to racial, ethnic and socioeconomic inequities in colorectal cancer outcomes. The full cost of screening – including noninvasive tests and follow-up colonoscopies – should be covered without cost to patients.”

Eliminating disparities in screening

Among the position statements, Dr. Lieberman and colleagues first called for “development of a national approach to CRC screening” to patch gaps in access across the United States.

“Systematic outreach occurs infrequently,” they noted. “CRC screening prevalence is much lower among individuals who do not have access to health care due to lack of insurance, do not have a primary care provider, or are part of a medically underserved community.”

According to Dr. Lieberman and colleagues, the AGA is also “working with a broad coalition of stakeholders,” such as the American Cancer Society, payers, patient advocacy groups, and others, to create a “national resource ... focused on ensuring high-quality CRC screening and eliminating barriers to CRC screening.”

Specifically, the coalition will work to collectively tackle “disparities created by social determinants of health, which includes lack of access to screening, transportation, and even work hours and child care.

“The AGA recognizes that moving the needle to achieve a CRC screening participation goal of 80% will take a village,” they wrote.

Elements of high-quality CRC screening

The investigators went on to describe the key features of a high-quality CRC screening program, including “colonoscopy and noninvasive screening options, patient education, outreach, and navigation support.”

Dr. Lieberman and colleagues pointed out that offering more than one type of screening test “acknowledges patient preferences and improves participation.”

Certain noninvasive methods, such as fecal immunochemical testing (FIT), eliminate “important barriers” to screening, they noted, such as the need for special preparation, time off work, and transportation to a medical facility.

For individuals who have high-risk adenomas (HRAs) or advanced sessile serrated lesions (SSLs), screening should be expanded to include follow-up, the investigators added.

“Evidence from a systematic review demonstrates that individuals with HRAs at baseline have a 3- to 4-fold higher risk of incident CRC during follow-up compared with individuals with no adenoma or low-risk adenomas,” they wrote. “There is also evidence that individuals with advanced SSLs have a three= to fourfold higher risk of CRC, compared with individuals with nonadvanced SSLs.”
 

Payers should cover costs

To further improve access to care, payers should cover the full costs of CRC screening because “copays and deductibles are barriers to screening and contribute to socioeconomic disparities,” that “disproportionately impact those with low income and lack of insurance,” according to Dr. Lieberman and colleagues.

They noted that the Affordable Care Act “eliminated copayments for preventive services,” yet a recent study showed that almost half of patients with commercial insurance and more than three-quarters of patients with Medicare still share some cost of CRC screening.

The investigators made clear that payers need to cover costs from start to finish, including “bowel preparation, facility and professional fees, anesthesia, and pathology,” as well as follow-up screening for high-risk patients identified by noninvasive methods.

“Noninvasive colorectal screening should be considered as programs with multiple steps, each of which, including follow-up colonoscopy if the test is positive, should be covered by payers without cost sharing as part of the screening continuum,” Dr. Lieberman and colleagues wrote.
 

Changes underway

According to Steven Itzkowitz, MD, professor of medicine and oncological sciences and director of the gastroenterology fellowship training program at the Icahn School of Medicine at Mount Sinai, New York, the AGA publication is important because it “consolidates many of the critical issues related to decreasing the burden of colorectal cancer in the United States.”

Dr. Itzkowitz noted that changes are already underway to eliminate cost as a barrier to screening.

“The good news is that, in the past year, the Departments of Health & Human Services, Labor, and Treasury declared that cost sharing should not be imposed, and plans are required to cover screening colonoscopy with polyp removal and colonoscopy that is performed to follow-up after an abnormal noninvasive CRC screening test,” Dr. Itzkowitz said in an interview. “Many plans are following suit, but it will take time for this coverage to take effect across all plans.”

For individual gastroenterologists who would like to do their part in reducing screening inequity, Dr. Itzkowitz suggested leveraging noninvasive testing, as the AGA recommends.

“This publication is the latest to call for using noninvasive, stool-based testing in addition to colonoscopy,” Dr. Itzkowitz said. “FIT and multitarget stool DNA tests all have proven efficacy in this regard, so gastroenterologists should have those conversations with their patients. GIs can also make it easier for patients to complete colonoscopy by developing patient navigation programs, direct access referrals, and systems for communicating with primary care providers for easier referrals and communicating colonoscopy results.”

Many practices are already instituting such improvements in response to the restrictions imposed by the COVID-19 pandemic, according to Dr. Itzkowitz.“These changes, plus better coverage by payers, will make a huge impact on health equity when it comes to colorectal cancer screening.”

The publication was supported by the AGA. The investigators disclosed relationships with Geneoscopy, ColoWrap, UniversalDx, and others. Dr. Itzkowitz disclosed no relevant conflicts of interest.

The full cost of screening – including noninvasive tests and follow-up colonoscopies – should be covered without cost to patients.”

Eliminating disparities in screening

Among the position statements, Dr. Lieberman and colleagues first called for “development of a national approach to CRC screening” to patch gaps in access across the United States.

“Systematic outreach occurs infrequently,” they noted. “CRC screening prevalence is much lower among individuals who do not have access to health care due to lack of insurance, do not have a primary care provider, or are part of a medically underserved community.”

According to Dr. Lieberman and colleagues, the AGA is also “working with a broad coalition of stakeholders,” such as the American Cancer Society, payers, patient advocacy groups, and others, to create a “national resource ... focused on ensuring high-quality CRC screening and eliminating barriers to CRC screening.”

Specifically, the coalition will work to collectively tackle “disparities created by social determinants of health, which includes lack of access to screening, transportation, and even work hours and child care.

“The AGA recognizes that moving the needle to achieve a CRC screening participation goal of 80% will take a village,” they wrote.

Elements of high-quality CRC screening

The investigators went on to describe the key features of a high-quality CRC screening program, including “colonoscopy and noninvasive screening options, patient education, outreach, and navigation support.”

Dr. Lieberman and colleagues pointed out that offering more than one type of screening test “acknowledges patient preferences and improves participation.”

Certain noninvasive methods, such as fecal immunochemical testing (FIT), eliminate “important barriers” to screening, they noted, such as the need for special preparation, time off work, and transportation to a medical facility.

For individuals who have high-risk adenomas (HRAs) or advanced sessile serrated lesions (SSLs), screening should be expanded to include follow-up, the investigators added.

“Evidence from a systematic review demonstrates that individuals with HRAs at baseline have a 3- to 4-fold higher risk of incident CRC during follow-up compared with individuals with no adenoma or low-risk adenomas,” they wrote. “There is also evidence that individuals with advanced SSLs have a three= to fourfold higher risk of CRC, compared with individuals with nonadvanced SSLs.”
 

Payers should cover costs

To further improve access to care, payers should cover the full costs of CRC screening because “copays and deductibles are barriers to screening and contribute to socioeconomic disparities,” that “disproportionately impact those with low income and lack of insurance,” according to Dr. Lieberman and colleagues.

They noted that the Affordable Care Act “eliminated copayments for preventive services,” yet a recent study showed that almost half of patients with commercial insurance and more than three-quarters of patients with Medicare still share some cost of CRC screening.

The investigators made clear that payers need to cover costs from start to finish, including “bowel preparation, facility and professional fees, anesthesia, and pathology,” as well as follow-up screening for high-risk patients identified by noninvasive methods.

“Noninvasive colorectal screening should be considered as programs with multiple steps, each of which, including follow-up colonoscopy if the test is positive, should be covered by payers without cost sharing as part of the screening continuum,” Dr. Lieberman and colleagues wrote.
 

Changes underway

According to Steven Itzkowitz, MD, professor of medicine and oncological sciences and director of the gastroenterology fellowship training program at the Icahn School of Medicine at Mount Sinai, New York, the AGA publication is important because it “consolidates many of the critical issues related to decreasing the burden of colorectal cancer in the United States.”

Dr. Itzkowitz noted that changes are already underway to eliminate cost as a barrier to screening.

“The good news is that, in the past year, the Departments of Health & Human Services, Labor, and Treasury declared that cost sharing should not be imposed, and plans are required to cover screening colonoscopy with polyp removal and colonoscopy that is performed to follow-up after an abnormal noninvasive CRC screening test,” Dr. Itzkowitz said in an interview. “Many plans are following suit, but it will take time for this coverage to take effect across all plans.”

For individual gastroenterologists who would like to do their part in reducing screening inequity, Dr. Itzkowitz suggested leveraging noninvasive testing, as the AGA recommends.

“This publication is the latest to call for using noninvasive, stool-based testing in addition to colonoscopy,” Dr. Itzkowitz said. “FIT and multitarget stool DNA tests all have proven efficacy in this regard, so gastroenterologists should have those conversations with their patients. GIs can also make it easier for patients to complete colonoscopy by developing patient navigation programs, direct access referrals, and systems for communicating with primary care providers for easier referrals and communicating colonoscopy results.”

Many practices are already instituting such improvements in response to the restrictions imposed by the COVID-19 pandemic, according to Dr. Itzkowitz.“These changes, plus better coverage by payers, will make a huge impact on health equity when it comes to colorectal cancer screening.”

The publication was supported by the AGA. The investigators disclosed relationships with Geneoscopy, ColoWrap, UniversalDx, and others. Dr. Itzkowitz disclosed no relevant conflicts of interest.

The American Gastroenterological Association has published eight position statements aimed at reducing the burden of colorectal cancer (CRC).

The evidence-based statements, published in Gastroenterology, call for a national approach to CRC screening, outline the elements of a high-quality screening program, and make clear that payers should cover all costs, from bowel prep through pathology, plus follow-up for high-risk patients.

NEW ORLEANS – The case continues to grow for prioritizing a sodium-glucose transporter 2 (SGLT2) inhibitor in patients with type 2 diabetes, as real-world evidence of benefit and safety accumulates on top of the data from randomized trials that first established this class as a management pillar.

Another important effect of these agents gaining increasing currency, on top of their well-established benefits in patients with type 2 diabetes for preventing acute heart failure exacerbations and slowing progression of diabetic kidney disease, is that they cut the incidence of new-onset atrial fibrillation (AFib). That effect was confirmed in an analysis of data from about 300,000 U.S. patients included in recent Medicare records, Elisabetta Patorno, MD, reported at the annual scientific sessions of the American Diabetes Association.

Mitchel L. Zoler/MDedge News

But despite documentation like this, real-world evidence also continues to show limited uptake of SGLT2 inhibitors in U.S. patients with type 2 diabetes. Records from more than 1.3 million patients with type 2 diabetes managed in the Veterans Affairs Healthcare System during 2019 or 2022 documented that just 10% of these patients received an agent from this class, even though all were eligible to receive it, according to findings in a separate report at the meeting.

The AFib analysis analyzed two sets of propensity score–matched Medicare patients during 2013-2018 aged 65 years or older with type 2 diabetes and no history of AFib. One analysis focused on 80,475 matched patients who started on treatment with either an SGLT2 inhibitor or a glucagonlike peptide–1 (GLP-1) receptor agonist, and a second on 74,868 matched patients who began either an SGTL2 inhibitor or a dipeptidyl peptidase–4 (DPP4) inhibitor. In both analyses, matching involved more than 130 variables. In both pair sets, patients at baseline averaged about 72 years old, nearly two-thirds were women, about 8%-9% had heart failure, 77%-80% were on metformin, and 20%-25% were using insulin.

The study’s primary endpoint was the incidence of hospitalization for AFib, which occurred a significant 18% less often in the patients who started on an SGLT2, compared with those who started a DPP4 inhibitor during median follow-up of 6.7 months, and a significant 10% less often, compared with those starting a GLP-1 receptor agonist during a median follow-up of 6.0 months, Elisabetta Patorno, MD, DrPH, reported at the meeting. This worked out to 3.7 fewer hospitalizations for AFib per 1,000 patient-years of follow-up among the people who received an SGLT2 inhibitor, compared with a DPP4 inhibitor, and a decrease of 1.8 hospitalizations/1,000 patient-years when compared against patients in a GLP-1 receptor agonist.

Two secondary outcomes showed significantly fewer episodes of newly diagnosed AFib, and significantly fewer patients initiating AFib treatment among those who received an SGLT2 inhibitor relative to the comparator groups. In addition, these associations were consistent across subgroup analyses that divided patients by their age, sex, history of heart failure, and history of atherosclerotic cardiovascular disease.
 

AFib effects add to benefits

The findings “suggest that initiation of an SGLT2 inhibitor may be beneficial in older adults with type 2 diabetes who are at risk for AFib,” said Dr. Patorno, a researcher in the division of pharmacoepidemiology and pharmacoeconomics at Brigham and Women’s Hospital, Boston. “These new findings on AFib may be helpful when weighing the potential risks and benefits of various glucose-lowering drugs in older patients with type 2 diabetes.”

This new evidence follows several prior reports from other research groups of data supporting an AFib benefit from SGLT2 inhibitors. The earlier reports include a post hoc analysis of more than 17,000 patients enrolled in the DECLARE-TIMI 58 cardiovascular outcome trial of dapagliflozin (Farxiga), which showed a 19% relative decrease in the rate of incident AFib or atrial flutter events during a median 4.2 year follow-up.

Other prior reports that found a reduced incidence of AFib events linked with SGLT2 inhibitor treatment include a 2020 meta-analysis based on data from more than 38,000 patients with type 2 diabetes enrolled in any of 16 randomized, controlled trials, which found a 24% relative risk reduction. And an as-yet unpublished report from researchers at the University of Rochester (N.Y.) and their associates presented in November 2021 at the annual scientific sessions of the American Heart Association that documented a significant 24% relative risk reduction in incident AFib events linked to SGLT2 inhibitor treatment in a prospective study of 13,890 patients at several hospitals in Israel or the United States.
 

Evidence ‘convincing’ in totality

The accumulated evidence for a reduced incidence of AFib when patients were on treatment with an SGLT2 inhibitor are “convincing because it’s real world data that complements what we know from clinical trials,” commented Silvio E. Inzucchi, MD, professor of medicine at Yale University and director of the Yale Medicine Diabetes Center in New Haven, Conn., who was not involved with the study.

“If these drugs reduce heart failure, they may also reduce AFib. Heart failure patients easily slip into AFib,” he noted in an interview, but added that “I don’t think this explains all cases” of the reduced AFib incidence.

Dr. Patorno offered a few other possible mechanisms for the observed effect. The class may work by reducing blood pressure, weight, inflammation, and oxidative stress, mitochondrial dysfunction, atrial remodeling, and AFib susceptibility. These agents are also known to cause natriuresis and diuresis, which could reduce atrial dilation, a mechanism that again relates the AFib effect to the better documented reduction in acute heart failure exacerbations.

“With the diuretic effect, we’d expect less overload at the atrium and less dilation, and the same mechanism would reduce heart failure,” she said in an interview.

“If you reduce preload and afterload you may reduce stress on the ventricle and reduce atrial stretch, and that might have a significant effect on atrial arrhythmia,” agreed Dr. Inzucchi.
 

EMPRISE produces more real-world evidence

A pair of additional reports at the meeting that Dr. Patorno coauthored provided real-world evidence supporting the dramatic heart failure benefit of the SGLT2 inhibitor empagliflozin (Jardiance) in U.S. patients with type 2 diabetes, compared with alternative drug classes. The EMPRISE study used data from the Medicare, Optum Clinformatics, and MarketScan databases during the period from August 2014, when empagliflozin became available, to September 2019. The study used more than 140 variables to match patients treated with either empagliflozin or a comparator agent.

The results showed that, in an analysis of more than 130,000 matched pairs, treatment with empagliflozin was linked to a significant 30% reduction in the incidence of hospitalization for heart failure, compared with patients treated with a GLP-1 receptor agonist. Analysis of more than 116,000 matched pairs of patients showed that treatment with empagliflozin linked with a significant 29%-50% reduced rate of hospitalization for heart failure, compared with matched patients treated with a DPP4 inhibitor.

These findings “add to the pool of information” on the efficacy of agents from the SGLT2 inhibitor class, Dr. Patorno said in an interview. “We wanted to look at the full range of patients with type 2 diabetes who we see in practice,” rather than the more selected group of patients enrolled in randomized trials.

SGLT2 inhibitor use lags even when cost isn’t an issue

Despite all the accumulated evidence for efficacy and safety of the class, usage remains low, Julio A. Lamprea-Montealegre, MD, PhD, a cardiologist at the University of California, San Francisco, reported in a separate talk at the meeting. The study he presented examined records for 1,319,500 adults with type 2 diabetes managed in the VA Healthcare System during 2019 and 2020. Despite being in a system that “removes the influence of cost,” just 10% of these patients received treatment with an SGLT2 inhibitor, and 7% received treatment with a GLP-1 receptor agonist.

Notably, his analysis further showed that treatment with an SGLT2 inhibitor was especially depressed among patients with an estimated glomerular filtration rate (eGFR) of 30-44 mL/min per 1.73m². In this subgroup, usage of a drug from this class was at two-thirds of the rate, compared with patients with an eGFR of at least 90 mL/min per 1.73m2. His findings also documented lower rates of use in patients with higher risk for atherosclerotic cardiovascular disease. Dr. Lamprea-Montealegre called this a “treatment paradox,” in which patients likely to get the most benefit from an SGLT2 inhibitor were also less likely to actually receive it.

While his findings from the VA System suggest that drug cost is not the only factor driving underuse, the high price set for the SGLT2 inhibitor drugs that all currently remain on U.S. patents is widely considered an important factor.

“There is a big problem of affordability,” said Dr. Patorno.

“SGLT2 inhibitors should probably be first-line therapy” for many patients with type 2 diabetes, said Dr. Inzucchi. “The only thing holding it back is cost,” a situation that he hopes will dramatically shift once agents from this class become generic and have substantially lower price tags.

The EMPRISE study received funding from Boehringer Ingelheim, the company that markets empagliflozin (Jardiance). Dr. Patorno had no relevant commercial disclosures. Dr. Inzucchi is an adviser to Abbott Diagnostics, Esperion Therapeutics, and vTv Therapeutics, a consultant to Merck and Pfizer, and has other relationships with AstraZeneca, Boehringer Ingelheim, Lexicon, and Novo Nordisk. Dr. Lamprea-Montealegre had received research funding from Bayer.

AFib effects add to benefits

The findings “suggest that initiation of an SGLT2 inhibitor may be beneficial in older adults with type 2 diabetes who are at risk for AFib,” said Dr. Patorno, a researcher in the division of pharmacoepidemiology and pharmacoeconomics at Brigham and Women’s Hospital, Boston. “These new findings on AFib may be helpful when weighing the potential risks and benefits of various glucose-lowering drugs in older patients with type 2 diabetes.”

This new evidence follows several prior reports from other research groups of data supporting an AFib benefit from SGLT2 inhibitors. The earlier reports include a post hoc analysis of more than 17,000 patients enrolled in the DECLARE-TIMI 58 cardiovascular outcome trial of dapagliflozin (Farxiga), which showed a 19% relative decrease in the rate of incident AFib or atrial flutter events during a median 4.2 year follow-up.

Other prior reports that found a reduced incidence of AFib events linked with SGLT2 inhibitor treatment include a 2020 meta-analysis based on data from more than 38,000 patients with type 2 diabetes enrolled in any of 16 randomized, controlled trials, which found a 24% relative risk reduction. And an as-yet unpublished report from researchers at the University of Rochester (N.Y.) and their associates presented in November 2021 at the annual scientific sessions of the American Heart Association that documented a significant 24% relative risk reduction in incident AFib events linked to SGLT2 inhibitor treatment in a prospective study of 13,890 patients at several hospitals in Israel or the United States.
 

Evidence ‘convincing’ in totality

The accumulated evidence for a reduced incidence of AFib when patients were on treatment with an SGLT2 inhibitor are “convincing because it’s real world data that complements what we know from clinical trials,” commented Silvio E. Inzucchi, MD, professor of medicine at Yale University and director of the Yale Medicine Diabetes Center in New Haven, Conn., who was not involved with the study.

“If these drugs reduce heart failure, they may also reduce AFib. Heart failure patients easily slip into AFib,” he noted in an interview, but added that “I don’t think this explains all cases” of the reduced AFib incidence.

Dr. Patorno offered a few other possible mechanisms for the observed effect. The class may work by reducing blood pressure, weight, inflammation, and oxidative stress, mitochondrial dysfunction, atrial remodeling, and AFib susceptibility. These agents are also known to cause natriuresis and diuresis, which could reduce atrial dilation, a mechanism that again relates the AFib effect to the better documented reduction in acute heart failure exacerbations.

“With the diuretic effect, we’d expect less overload at the atrium and less dilation, and the same mechanism would reduce heart failure,” she said in an interview.

“If you reduce preload and afterload you may reduce stress on the ventricle and reduce atrial stretch, and that might have a significant effect on atrial arrhythmia,” agreed Dr. Inzucchi.
 

EMPRISE produces more real-world evidence

A pair of additional reports at the meeting that Dr. Patorno coauthored provided real-world evidence supporting the dramatic heart failure benefit of the SGLT2 inhibitor empagliflozin (Jardiance) in U.S. patients with type 2 diabetes, compared with alternative drug classes. The EMPRISE study used data from the Medicare, Optum Clinformatics, and MarketScan databases during the period from August 2014, when empagliflozin became available, to September 2019. The study used more than 140 variables to match patients treated with either empagliflozin or a comparator agent.

The results showed that, in an analysis of more than 130,000 matched pairs, treatment with empagliflozin was linked to a significant 30% reduction in the incidence of hospitalization for heart failure, compared with patients treated with a GLP-1 receptor agonist. Analysis of more than 116,000 matched pairs of patients showed that treatment with empagliflozin linked with a significant 29%-50% reduced rate of hospitalization for heart failure, compared with matched patients treated with a DPP4 inhibitor.

These findings “add to the pool of information” on the efficacy of agents from the SGLT2 inhibitor class, Dr. Patorno said in an interview. “We wanted to look at the full range of patients with type 2 diabetes who we see in practice,” rather than the more selected group of patients enrolled in randomized trials.

SGLT2 inhibitor use lags even when cost isn’t an issue

Despite all the accumulated evidence for efficacy and safety of the class, usage remains low, Julio A. Lamprea-Montealegre, MD, PhD, a cardiologist at the University of California, San Francisco, reported in a separate talk at the meeting. The study he presented examined records for 1,319,500 adults with type 2 diabetes managed in the VA Healthcare System during 2019 and 2020. Despite being in a system that “removes the influence of cost,” just 10% of these patients received treatment with an SGLT2 inhibitor, and 7% received treatment with a GLP-1 receptor agonist.

Notably, his analysis further showed that treatment with an SGLT2 inhibitor was especially depressed among patients with an estimated glomerular filtration rate (eGFR) of 30-44 mL/min per 1.73m². In this subgroup, usage of a drug from this class was at two-thirds of the rate, compared with patients with an eGFR of at least 90 mL/min per 1.73m2. His findings also documented lower rates of use in patients with higher risk for atherosclerotic cardiovascular disease. Dr. Lamprea-Montealegre called this a “treatment paradox,” in which patients likely to get the most benefit from an SGLT2 inhibitor were also less likely to actually receive it.

While his findings from the VA System suggest that drug cost is not the only factor driving underuse, the high price set for the SGLT2 inhibitor drugs that all currently remain on U.S. patents is widely considered an important factor.

“There is a big problem of affordability,” said Dr. Patorno.

“SGLT2 inhibitors should probably be first-line therapy” for many patients with type 2 diabetes, said Dr. Inzucchi. “The only thing holding it back is cost,” a situation that he hopes will dramatically shift once agents from this class become generic and have substantially lower price tags.

The EMPRISE study received funding from Boehringer Ingelheim, the company that markets empagliflozin (Jardiance). Dr. Patorno had no relevant commercial disclosures. Dr. Inzucchi is an adviser to Abbott Diagnostics, Esperion Therapeutics, and vTv Therapeutics, a consultant to Merck and Pfizer, and has other relationships with AstraZeneca, Boehringer Ingelheim, Lexicon, and Novo Nordisk. Dr. Lamprea-Montealegre had received research funding from Bayer.

Herpes zoster does not appear to increase dementia risk – on the contrary, the viral infection may offer some protection, a large population-based study suggests.

“We were surprised by these results [and] the reasons for the decreased risk are unclear,” study author Sigrun Alba Johannesdottir Schmidt, MD, PhD, with Aarhus (Denmark) University Hospital, said in a news release.

The study was published online in Neurology.
 

Conflicting findings

Herpes zoster (HZ) is an acute, cutaneous viral infection caused by the reactivation of varicella-zoster virus (VZV). Previous population-based studies have reported both decreased and increased risks of dementia after having HZ.

It’s thought that HZ may contribute to the development of dementia through neuroinflammation, cerebral vasculopathy, or direct neural damage, but epidemiologic evidence is limited.

To investigate further, Dr. Schmidt and colleagues used Danish medical registries to identify 247,305 people who had visited a hospital for HZ or were prescribed antiviral medication for HZ over a 20-year period and matched them to 1,235,890 people who did not have HZ. For both cohorts, the median age was 64 years, and 61% were women.

Dementia was diagnosed in 9.7% of zoster patients and 10.3% of matched control persons during up to 21 years of follow-up.

Contrary to the researchers’ expectation, HZ was associated with a small (7%) decreased relative risk of all-cause dementia during follow-up (hazard ratio, 0.93; 95% confidence interval, 0.90-0.95).

There was no increased long-term risk of dementia in subgroup analyses, except possibly among those with HZ that involved the central nervous system (HR, 1.94; 95% CI, 0.78-4.80), which has been shown before.

However, the population attributable fraction of dementia caused by this rare complication is low (< 1%), suggesting that universal vaccination against VZV in the elderly has limited potential to reduce dementia risk, the investigators noted.

Nonetheless, Dr. Schmidt said shingles vaccination should be encouraged in older people because it can prevent complications from the disease.

The research team admitted that the slightly decreased long-term risk of dementia, including Alzheimer’s disease, was “unexpected.” The reasons for this decreased risk are unclear, they say, and could be explained by missed diagnoses of shingles in people with undiagnosed dementia.

They were not able to examine whether antiviral treatment modifies the association between HZ and dementia and said that this topic merits further research.

The study was supported by the Edel and Wilhelm Daubenmerkls Charitable Foundation. The authors disclosed no relevant financial relationships.

Patients successfully resuscitated after an out-of-hospital cardiac arrest who did not have ST-segment elevation on their electrocardiogram did not benefit from emergency coronary angiography in a new randomized clinical trial.

In the EMERGE trial, a strategy of emergency coronary angiography was not found to be better than a strategy of delayed coronary angiography with respect to the 180-day survival rate with no or minimal neurologic sequelae.

The authors note that, although the study was underpowered, the results are consistent with previously published studies and do not support routine emergency coronary angiography in survivors of out-of-hospital cardiac arrest without ST elevation.

But senior author, Christian Spaulding, MD, PhD, European Hospital Georges Pompidou, Paris, believes some such patients may still benefit from emergency angiography.

“Most patients who have been resuscitated after out of hospital cardiac arrest will have neurological damage, which will be the primary cause of death,” Dr. Spaulding told this news organization. “It will not make any difference to these patients if they have a coronary lesion treated. So, going forward, I think we need to look for patients who are likely not to have a high degree of neurological damage and who could still benefit from early angiography.”

The EMERGE study was published online  in JAMA Cardiology.

In patients who have suffered an out-of-hospital cardiac arrest with no obvious noncardiac cause such as trauma, it is believed that the cardiac arrest is caused by coronary occlusions, and emergency angiography may be able to improve survival in these patients, Dr. Spaulding explained.

In about one-third of such patients, the ECG before hospitalization shows ST elevation, and in this group, there is a high probability (around 70%-80%) that there is going to be a coronary occlusion, so these patients are usually taken directly to emergency angiography.

But, in the other two-thirds of patients, there is no ST elevation on the ECG, and in these patients the chances of finding a coronary occlusion are lower (around 25%-35%).

The EMERGE trial was conducted in this latter group without ST elevation.

For the study, which was conducted in 22 French centers, 279 such patients (mean age, 64 years) were randomized to either emergency or delayed (48-96 hours) coronary angiography. The mean time delay between randomization and coronary angiography was 0.6 hours in the emergency group and 55.1 hours in the delayed group.

The primary outcome was the 180-day survival rate with minimal neurological damage, defined as Cerebral Performance Category of 2 or less. This occurred in 34.1% of the emergency angiography group and 30.7% of the delayed angiography group (hazard ratio, 0.87; 95% confidence interval, 0.65-1.15; P = .32).

There was also no difference in the overall survival rate at 180 days (36.2% vs. 33.3%; HR, 0.86; P = .31) and in secondary outcomes between the two groups.

Dr. Spaulding noted that three other randomized trials in a similar patient population have all shown similar results, with no difference in survival found between patients who have emergency coronary angiography as soon as they are admitted to hospital and those in whom angiography was not performed until a couple of days later.

However, several registry studies in a total of more than 6,000 patients have suggested a benefit of immediate angiography in these patients. “So, there is some disconnect here,” he said.

Dr. Spaulding believes the reason for this disconnect may be that the registry studies may have included patients with less neurological damage so more likely to survive and to benefit from having coronary lesions treated promptly.

“Paramedics sometimes make a judgment on which patients may have minimal neurological damage, and this may affect the choice of hospital a patient is taken to, and then the emergency department doctor may again assess whether a patient should go for immediate angiography or not. So, patients in these registry studies who received emergency angiography were likely already preselected to some extent,” he suggested.

In contrast, the randomized trials have accepted all patients, so there were probably more with neurological damage. “In our trial, almost 70% of patients were in asystole. These are the ones who [are] the most likely to have neurological damage,” he pointed out.

“Because there was such a striking difference in the registry studies, I think there is a group of patients [who] will benefit from immediate emergency coronary angiography, but we have to work out how to select these patients,” he commented.

Dr. Spaulding noted that a recent registry study published in JACC: Cardiovascular Interventions used a score known as MIRACLE2, (which takes into account various factors including age of patient and type of rhythm on ECG) and the degree of cardiogenic shock on arrival at hospital as measured by the SCAI shock score to define a potential cohort of patients at low risk for neurologic injury who benefit most from immediate coronary angiography.

“In my practice at present, I would advise the emergency team that a young patient who had had resuscitation started quickly, had been defibrillated early, and got to hospital quickly should go for an immediate coronary angiogram. It can’t do any harm, and there may be a benefit in such patients,” Dr. Spaulding added.The EMERGE study was supported in part by Assistance Publique–Hôpitaux de Paris and the French Ministry of Health, through the national Programme Hospitalier de Recherche Clinique. Dr. Spaulding reports no relevant financial relationships.

Goal-directed glycemic management – which may include new technologies for glucose monitoring – for non–critically ill hospitalized patients who have diabetes or newly recognized hyperglycemia can improve outcomes, according to a new practice guideline from the Endocrine Society.  

Even though roughly 35% of hospitalized patients have diabetes or newly discovered hyperglycemia, there is “wide variability in glycemic management in clinical practice,” writing panel chair Mary Korytkowski, MD, from the University of Pittsburgh, said at the annual meeting of the Endocrine Society. “These patients get admitted to every patient service in the hospital, meaning that every clinical service will encounter this group of patients, and their glycemic management can have a major effect on their outcomes. Both short term and long term.”

This guideline provides strategies “to achieve previously recommended glycemic goals while also reducing the risk for hypoglycemia, and this includes inpatient use of insulin pump therapy or continuous glucose monitoring [CGM] devices, among others,” she said.

It also includes “recommendations for preoperative glycemic goals as well as when the use of correctional insulin – well known as sliding scale insulin – may be appropriate” and when it is not.

The document, which replaces a 2012 guideline, was published online in the Journal of Clinical Endocrinology & Metabolism.

A multidisciplinary panel developed the document over the last 3 years to answer 10 clinical practice questions related to management of non–critically ill hospitalized patients with diabetes or newly discovered hyperglycemia.
 

Use of CGM devices in hospital

The first recommendation is: “In adults with insulin-treated diabetes hospitalized for noncritical illness who are at high risk of hypoglycemia, we suggest the use of real-time [CGM] with confirmatory bedside point-of-care blood glucose monitoring for adjustments in insulin dosing rather than point-of-care blood glucose rather than testing alone in hospital settings where resources and training are available.” (Conditional recommendation. Low certainty of evidence).

“We were actually very careful in terms of looking at the data” for use of CGMs, Dr. Korytkowski said in an interview.

Although CGMs are approved by the Food and Drug Administration in the outpatient setting, and that’s becoming the standard of care there, they are not yet approved for in-hospital use.

However, the FDA granted an emergency allowance for use of CGMs in hospitals during the COVID-19 pandemic.

That was “when everyone was scrambling for what to do,” Dr. Korytkowski noted. “There was a shortage of personal protective equipment and a real interest in trying to limit the amount of exposure of healthcare personnel in some of these really critically ill patients for whom intravenous insulin therapy was used to control their glucose level.”

On March 1, the FDA granted Breakthrough Devices Designation for Dexcom CGM use in the hospital setting.

The new guideline suggests CGM be used to detect trends in glycemic management, with insulin dosing decisions made with point-of-care glucose measure (the standard of care).

To implement CGM for glycemic management in hospitals, Dr. Korytkowski said, would require “extensive staff and nursing education to have people with expertise available to provide support to nursing personnel who are both placing these devices, changing these devices, looking at trends, and then knowing when to remove them for certain procedures such as MRI or radiologic procedures.”

“We know that not all hospitals may be readily available to use these devices,” she said. “It is an area of active research. But the use of these devices during the pandemic, in both critical care and non–critical care setting has really provided us with a lot of information that was used to formulate this suggestion in the guideline.”

The document addresses the following areas: CGM, continuous subcutaneous insulin infusion pump therapy, inpatient diabetes education, prespecified preoperative glycemic targets, use of neutral protamine Hagedorn insulin for glucocorticoid or enteral nutrition-associated hyperglycemia, noninsulin therapies, preoperative carbohydrate-containing oral fluids, carbohydrate counting for prandial (mealtime) insulin dosing, and correctional and scheduled (basal or basal bolus) insulin therapies.

Nine key recommendations

Dr. Korytkowski identified nine key recommendations:

• CGM systems can help guide glycemic management with reduced risk for hypoglycemia.
• Patients experiencing glucocorticoid- or enteral nutrition–associated hyperglycemia require scheduled insulin therapy to address anticipated glucose excursions.
• Selected patients using insulin pump therapy prior to a hospital admission can continue to use these devices in the hospital if they have the mental and physical capacity to do so with knowledgeable hospital personnel.
• Diabetes self-management education provided to hospitalized patients can promote improved glycemic control following discharge with reductions in the risk for hospital readmission. “We know that is recommended for patients in the outpatient setting but often they do not get this,” she said. “We were able to observe that this can also impact long-term outcomes “
• Patients with diabetes scheduled for elective surgery may have improved postoperative outcomes when preoperative hemoglobin A1c is 8% or less and preoperative blood glucose is less than 180 mg/dL. “This recommendation answers the question: ‘Where should glycemic goals be for people who are undergoing surgery?’ ”
• Providing preoperative carbohydrate-containing beverages to patients with known diabetes is not recommended.
• Patients with newly recognized hyperglycemia or well-managed diabetes on noninsulin therapy may be treated with correctional insulin alone as initial therapy at hospital admission.
• Some noninsulin diabetes therapies can be used in combination with correction insulin for patients with type 2 diabetes who have mild hyperglycemia.
• Correctional insulin – “otherwise known as sliding-scale insulin” –  can be used as initial therapy for patients with newly recognized hyperglycemia or type 2 diabetes treated with noninsulin therapy prior to hospital admission.
• Scheduled insulin therapy is preferred for patients experiencing persistent blood glucose values greater than 180 mg/dL and is recommended for patients using insulin therapy prior to admission. 

The guideline writers’ hopes

“We hope that this guideline will resolve debates” about appropriate preoperative glycemic management and when sliding-scale insulin can be used and should not be used, said Dr. Korytkowski.

The authors also hope that “it will stimulate research funding for this very important aspect of diabetes care, and that hospitals will recognize the importance of having access to knowledgeable diabetes care and education specialists who can provide staff education regarding inpatient glycemic management, provide oversight for patients using insulin pump therapy or CGM devices, and empower hospital nurses to provide diabetes [self-management] education prior to patient discharge.”

Claire Pegg, the patient representative on the panel, hopes “that this guideline serves as the beginning of a conversation that will allow inpatient caregivers to provide individualized care to patients – some of whom may be self-sufficient with their glycemic management and others who need additional assistance.” 

Development of the guideline was funded by the Endocrine Society. Dr. Korytkowski has reported no relevant financial disclosures.

Goal-directed glycemic management – which may include new technologies for glucose monitoring – for non–critically ill hospitalized patients who have diabetes or newly recognized hyperglycemia can improve outcomes, according to a new practice guideline from the Endocrine Society.  

Even though roughly 35% of hospitalized patients have diabetes or newly discovered hyperglycemia, there is “wide variability in glycemic management in clinical practice,” writing panel chair Mary Korytkowski, MD, from the University of Pittsburgh, said at the annual meeting of the Endocrine Society. “These patients get admitted to every patient service in the hospital, meaning that every clinical service will encounter this group of patients, and their glycemic management can have a major effect on their outcomes. Both short term and long term.”

This guideline provides strategies “to achieve previously recommended glycemic goals while also reducing the risk for hypoglycemia, and this includes inpatient use of insulin pump therapy or continuous glucose monitoring [CGM] devices, among others,” she said.

It also includes “recommendations for preoperative glycemic goals as well as when the use of correctional insulin – well known as sliding scale insulin – may be appropriate” and when it is not.

The document, which replaces a 2012 guideline, was published online in the Journal of Clinical Endocrinology & Metabolism.

A multidisciplinary panel developed the document over the last 3 years to answer 10 clinical practice questions related to management of non–critically ill hospitalized patients with diabetes or newly discovered hyperglycemia.
 

Use of CGM devices in hospital

The first recommendation is: “In adults with insulin-treated diabetes hospitalized for noncritical illness who are at high risk of hypoglycemia, we suggest the use of real-time [CGM] with confirmatory bedside point-of-care blood glucose monitoring for adjustments in insulin dosing rather than point-of-care blood glucose rather than testing alone in hospital settings where resources and training are available.” (Conditional recommendation. Low certainty of evidence).

“We were actually very careful in terms of looking at the data” for use of CGMs, Dr. Korytkowski said in an interview.

Although CGMs are approved by the Food and Drug Administration in the outpatient setting, and that’s becoming the standard of care there, they are not yet approved for in-hospital use.

However, the FDA granted an emergency allowance for use of CGMs in hospitals during the COVID-19 pandemic.

That was “when everyone was scrambling for what to do,” Dr. Korytkowski noted. “There was a shortage of personal protective equipment and a real interest in trying to limit the amount of exposure of healthcare personnel in some of these really critically ill patients for whom intravenous insulin therapy was used to control their glucose level.”

On March 1, the FDA granted Breakthrough Devices Designation for Dexcom CGM use in the hospital setting.

The new guideline suggests CGM be used to detect trends in glycemic management, with insulin dosing decisions made with point-of-care glucose measure (the standard of care).

To implement CGM for glycemic management in hospitals, Dr. Korytkowski said, would require “extensive staff and nursing education to have people with expertise available to provide support to nursing personnel who are both placing these devices, changing these devices, looking at trends, and then knowing when to remove them for certain procedures such as MRI or radiologic procedures.”

“We know that not all hospitals may be readily available to use these devices,” she said. “It is an area of active research. But the use of these devices during the pandemic, in both critical care and non–critical care setting has really provided us with a lot of information that was used to formulate this suggestion in the guideline.”

ATLANTA – Potential once-daily male oral contraceptives have passed a first clinical hurdle, showing a degree of testosterone suppression that should be sufficient for a contraceptive effect without causing symptomatic hypogonadism, according to phase 1 study results to be presented at the annual meeting of the Endocrine Society.

There are two pills in development and the studies so far suggest that both or a combination might be able to provide an acceptable balance of efficacy and tolerability, according to Tamar Jacobsohn, a researcher in the Contraceptive Development Program, Eunice Kennedy Shriver National Institute of Child Health and Human Development, Bethesda, Md.

The two drugs evaluated in this study are dimethandrolone undecanoate (DMAU) and 11b-methyl-19-nortestosterone-17b-dodecylcarbonate (11b-MNTDC). Both are bifunctional prodrugs with androgenic and progestogenic effects. The prodrugs are designed to be cleaved after ingestion so that the active hormones are released over 24 hours, permitting once-daily dosing.

“As potent androgens, these steroids suppress gonadotropin secretion, leading to markedly decreased serum testosterone production,” explained Ms. Jacobsohn in an interview.

However, she noted that there is still a long way to go on this research path. While the phase 1 studies have shown tolerability, the biology involved in suppressing sperm production suggests that men would need to take these pills daily for about 3 months at the very beginning of contraceptive treatment, until adequate sperm suppression is achieved to prevent pregnancy.

“We are working toward a phase 2 trial that will include a contraceptive efficacy endpoint, but there are lots of steps to get there, including more early phase studies,” she noted.

“There is a huge unmet need in terms of male contraceptive methods,” said Arthi Thirumalai, MBBS, an endocrinologist and assistant professor of medicine at the University of Washington School of Medicine in Seattle.

Senior author of a 2020 review article on male contraception, Dr. Thirumalai said in an interview that prodrugs and other hormonal methods to lower testosterone and suppress sperm production are attractive because of convenience, efficacy, and reversibility,

“We hope that oral formulations can be used to address this need,” said Dr. Thirumalai, who has participated in several experimental and clinical studies of male contraception methods. She is, in fact, one of the many coauthors of the data presented by Ms. Jacobsohn.

Ms. Jacobsohn emphasized: “Development of an effective, reversible male contraceptive method will improve reproductive options for men and women, have a major impact on public health by decreasing unintended pregnancy, and allow men to have an increasingly active role in family planning.”

Phase 1 results with DMAU and MNTDC

The work that led to phase 1 studies suggested that each of the drugs — DMAU and MNTDC — might provide adequate hormone suppression to reduce sperm counts without inducing unacceptable symptoms of hypogonadism. To test this potential, dose-ranging phase 1 studies with an endpoint of testosterone suppression were conducted with each one.

In the two placebo-controlled phase 1a studies, which are to be presented in a poster on June 13, healthy male subjects were randomly assigned to two pills of active therapy, four pills of active therapy, or placebo. In the two studies combined, 39 subjects received DMAU, 30 received 11b-MNTDC, and 28 received placebo.

Efficacy was evaluated by measuring testosterone levels. Tolerability was largely based on patient questionnaires.

At the end of 7 days, testosterone levels remained at reference levels (400 to 600 ng/dL) in those who received placebo. The levels fell to less than 100 ng/dL in all subjects assigned to an active agent regardless of which agent or dose was used.

From day 7 to 28, there was less median suppression of testosterone on 200 mg than 400 mg daily (92.7 ng/dL vs. 49.6 ng/dL; P < .001), but both remained below the target of 100 ng/dL, Ms. Jacobsohn reported.

The difference in degree of testosterone suppression did not appear to influence tolerability.

Subjects on four vs. two daily pills “did not report a significant difference in general satisfaction or their willingness to use the pills in the future or recommend them to other men,” said Ms. Jacobson, presenting P values for these outcomes among subjects on active therapy relative to placebo that were not significant, ranging from 0.48 to 0.85.

Overall, there were no serious adverse events. Mild side effects associated with hypogonadism did occur, but “all resolved by the end of the study,” she said.

Zero sperm production is not the goal. Lowering it sufficiently is

Dr. Thirumalai said the need for a male contraceptive is strong. While condoms have a substantial failure rate, vasectomy is not reliably reversible even though the majority of men agree that the responsibility for preventing pregnancy should be shared, she said.

Dr. Thirumalai’s earlier review article found that clinical trials of hormonal suppression to provide male contraception have been conducted for at least 30 years. The challenge has been finding an effective therapy that is well tolerated.

Drugs that combine both androgenic and progestogenic activity might be the answer. By manipulating hormones that lower testosterone, sperm production is reduced without eliminating a man’s ability to ejaculate. Zero sperm production is not the goal, according to data in Dr. Thirumalai’s review article.

Rather, studies suggest that when ejaculate contains less than 1 million sperm per mL (levels typically range from 15 to 200 million sperm/mL), the antipregnancy efficacy is similar to that achieved with female oral contraceptives.

However, clinical trials to demonstrate that this can be achieved safely have yet to be conducted.

Ms. Jacobsohn said that sperm half-life is about 3 months. This means that patients would need to be on hormonal therapy for a period of about this duration before reliable contraception is achieved.

In other words, the efficacy endpoint used in this current study [of 28 days duration] does not ensure effective contraception, but Ms. Jacobsohn suggested this is nevertheless an important step forward in clinical development.

Ms. Jacobsohn and Dr. Thirumalai report no relevant financial relationships.

CHARLOTTE, N.C. – Overnight sleep electroencephalography (EEG) contains an abundance of brain wave data that could be mined to identify an individual’s risk for a host of health outcomes, including dementia, cognitive impairment, and cardiovascular events, a researcher reported at the annual meeting of the Associated Professional Sleep Societies. “Sleep EEGs contain decodable information about the risk of unfavorable outcomes,” said Haoqi Sun, PhD, an instructor of neurology at Massachusetts General Hospital, Boston, and lead study author. “The results suggest that it’s feasible to use sleep to identify people with high risk of unfavorable outcomes and it strengthens the concept of sleep as a window into brain and general health.”

The researchers performed a quantitative analysis of sleep data collected on 8,673 adults who had diagnostic sleep studies that included polysomnography (PSG). The analysis used ICD codes to consider these 11 health outcomes: dementia, mild cognitive impairment (MCI) or dementia, ischemic stroke, intracranial hemorrhage, atrial fibrillation, myocardial infarction, type 2 diabetes, hypertension, bipolar disorder, depression, and mortality.

Then, Dr. Sun explained, they extracted 86 spectral and time-domain features of REM and non-REM sleep from sleep EEG recordings, and analyzed that data by adjusting for eight covariates including age, sex, body mass index, and use of benzodiazepines, antidepressants, sedatives, antiseizure drugs, and stimulants.

Participants were partitioned into three sleep-quality groups: poor, average, and good. The outcome-wise mean prediction difference in 10-year cumulative incidence was 2.3% for the poor sleep group, 0.5% for the average sleep group, and 1.3% for the good sleep group.

The outcomes with the three greatest poor to average risk ratios were dementia (6.2; 95% confidence interval, 4.5-9.3), mortality (5.7; 95% CI, 5-7.5) and MCI or dementia (4; 95% CI, 3.2-4.9).
 

Ready for the clinic?

In an interview, Dr. Sun said the results demonstrated the potential of using EEG brain wave data to predict health outcomes on an individual basis, although he acknowledged that most of the 86 sleep features the researchers used are not readily available in the clinic.

He noted the spectral features used in the study can be captured through software compatible with PSG. “From there you can identify the various bands, the different frequency ranges, and then you can easily see within this range whether a person has a higher power or lower power,” he said. However, the spindle and slow-oscillation features that researchers used in the study are beyond the reach of most clinics.
 

Next steps

This research is in its early stage, Dr. Sun said, but at some point the data collected from sleep studies could be paired with machine learning to make the model workable for evaluating individual patients. “Our goal is to first make this individualized,” he said. “We want to minimize the noise in the recording and minimize the night-to-night variability in the findings. There is some clinical-informed approach and there is also some algorithm-informed approach where you can minimize the variation over time.”

The model also has the potential to predict outcomes, particularly with chronic diseases such as diabetes and dementia, well before a diagnosis is made, he said.
 

‘Fascinating’ and ‘provocative’

Donald Bliwise, PhD, professor of neurology at Emory Sleep Center in Atlanta, said the study was “fascinating; it’s provocative; it’s exciting and interesting,” but added, “Sleep is vital for health. That’s abundantly clear in a study like that, but trying to push it a little bit further with all of these 86 measurements of the EEG, I think it becomes complicated.”

The study methodology, particularly the use of cumulative incidence of various diseases, was laudable, he said, and the use of simpler EEG-measured sleep features, such as alpha band power, “make intuitive sense.”

But it’s less clear on how the more sophisticated features the study model used – for example, kurtosis of theta frequency or coupling between spindle and slow oscillation – rank on sleep quality, he said, adding that the researchers have most likely done that but couldn’t add that into the format of the presentation.

“Kurtosis of the theta frequency band we don’t get on everyone in the sleep lab,” Dr. Bliwise said. “We might be able to, but I don’t know how to quite plug that into a turnkey model.”

The clinical components of the study were conducted by M. Brandon Westover, MD, PhD, at Massachusetts General Hospital, and Robert J. Thomas, MD, at Beth Israel Deaconess Medical Center, both in Boston. The study received support from the American Academy of Sleep Medicine Foundation. Dr. Sun has no relevant disclosures.

Opioid use in the elderly is associated with an almost 40% increased risk of dementia in new findings that suggest exposure to these drugs may be another modifiable risk factor for dementia.

“Clinicians and others may want to consider that opioid exposure in those aged 75-80 increases dementia risk, and to balance the potential benefits of opioid use in old age with adverse side effects,” said Stephen Z. Levine, PhD, professor, department of community mental health, University of Haifa (Israel).

The study was published online in the American Journal of Geriatric Psychiatry.
 

Widespread use

Evidence points to a relatively high rate of opioid prescriptions among older adults. A Morbidity and Mortality Weekly Report noted 19.2% of the U.S. adult population filled an opioid prescription in 2018, with the rate in those over 65 double that of adults aged 20-24 years (25% vs. 11.2%).

Disorders and illnesses for which opioids might be prescribed, including cancer and some pain conditions, “are far more prevalent in old age than at a younger age,” said Dr. Levine.

This high rate of opioid use underscores the need to consider the risks of opioid use in old age, said Dr. Levine. “Unfortunately, studies of the association between opioid use and dementia risk in old age are few, and their results are inconsistent.”

The study included 91,307 Israeli citizens aged 60 and over without dementia who were enrolled in the Meuhedet Healthcare Services, a nonprofit health maintenance organization (HMO) serving 14% of the country’s population. Meuhedet has maintained an up-to-date dementia registry since 2002.

The average age of the study sample was 68.29 years at the start of the study (in 2012).

In Israel, opioids are prescribed for a 30-day period. In this study, opioid exposure was defined as opioid medication fills covering 60 days (or two prescriptions) within a 120-day interval.

The primary outcome was incident dementia during follow-up from Jan. 1, 2013 to Oct. 30, 2017. The analysis controlled for a number of factors, including age, sex, smoking status, health conditions such as arthritis, depression, diabetes, osteoporosis, cognitive decline, vitamin deficiencies, cancer, cardiovascular conditions, and hospitalizations for falls.

Researchers also accounted for the competing risk of mortality.

During the study, 3.1% of subjects were exposed to opioids at a mean age of 73.94 years, and 5.8% of subjects developed dementia at an average age of 78.07 years.
 

Increased dementia risk

The risk of incident dementia was significantly increased in those exposed to opioids versus unexposed individuals in the 75- to 80-year age group (adjusted hazard ratio, 1.39; 95% confidence interval, 1.01-1.92; z statistic = 2.02; P < .05).

The authors noted the effect size for opioid exposure in this elderly age group is like other potentially modifiable risk factors for dementia, including body mass index and smoking.

The current study could not determine the biological explanation for the increased dementia risk among older opioid users. “Causal notions are challenging in observational studies and should be viewed with caution,” Dr. Levine noted.

However, a plausible mechanism highlighted in the literature is that opioids promote apoptosis of microglia and neurons that contribute to neurodegenerative diseases, he said.

The study included 14 sensitivity analyses, including those that looked at females, subjects older than 70, smokers, and groups with and without comorbid health conditions. The only sensitivity analysis that didn’t have similar findings to the primary analysis looked at dementia risk restricted to subjects without a vitamin deficiency.

“It’s reassuring that 13 or 14 sensitivity analyses found a significant association between opioid exposure and dementia risk,” said Dr. Levine.

Some prior studies did not show an association between opioid exposure and dementia risk. One possible reason for the discrepancy with the current findings is that the previous research didn’t account for age-specific opioid use effects, or the competing risk of mortality, said Dr. Levine.

Clinicians have a number of potential alternatives to opioids to treat various conditions including acetaminophen, non-steroidal anti-inflammatory drugs, amine reuptake inhibitors (ARIs), membrane stabilizers, muscle relaxants, topical capsaicin, botulinum toxin, cannabinoids, and steroids.

A limitation of the study was that it didn’t adjust for all possible comorbid health conditions, including vascular conditions, or for use of benzodiazepines, and surgical procedures.

In addition, since up to 50% of dementia cases are undetected, it’s possible some in the unexposed opioid group may actually have undiagnosed dementia, thereby reducing the effect sizes in the results.

Reverse causality is also a possibility as the neuropathological process associated with dementia could have started prior to opioid exposure. In addition, the results are limited to prolonged opioid exposure.
 

Interpret with caution

Commenting on the study, David Knopman, MD, a neurologist at Mayo Clinic in Rochester, Minn., whose research involves late-life cognitive disorders, was skeptical.

“On the face of it, the fact that an association was seen only in one narrow age range – 75+ to 80 years – ought to raise serious suspicion about the reliability and validity of the claim that opioid use is a risk factor for dementia, he said.

Although the researchers performed several sensitivity analyses, including accounting for mortality, “pharmacoepidemiological studies are terribly sensitive to residual biases” related to physician and patient choices related to medication use, added Dr. Knopman.

The claim that opioids are a dementia risk “should be viewed with great caution” and should not influence use of opioids where they’re truly indicated, he said.

“It would be a great pity if patients with pain requiring opioids avoid them because of fears about dementia based on the dubious relationship between age and opioid use.”

Dr. Levine and Dr. Knopman report no relevant financial disclosures.
