A “quadpill” containing quarter doses of four blood pressure (BP)–lowering medications was more effective than monotherapy for initial treatment of hypertension, with similar tolerability, in the 1-year, phase 3 QUARTET randomized, active-control trial.

Clara Chow, MD, PhD, academic director of the Westmead Applied Research Centre, University of Sydney, presented the findings in a late-breaking trial session at the annual congress of the European Society of Cardiology. The study was simultaneously published in The Lancet.

The primary outcome, mean unattended office BP at 12 weeks, dropped from 142/86 mm Hg to 120/71 mm Hg in patients who received the daily quadpill – a capsule containing irbesartan, amlodipine, indapamide, and bisoprolol – and fell from 140/83 mm Hg to 127/79 mm Hg in patients who received a daily full dose of irbesartan.

This 6.9 mm Hg greater drop in systolic BP at 12 months is clinically meaningful, Dr. Chow told this news organization. “If maintained, it would be expected to confer about a 15%-20% reduction” in heart disease, stroke, and heart failure.

In the SPRINT study, she noted, the final systolic BP was 120 mm Hg in the intervention group and 134 mm Hg in the control group, and the difference was associated with a 27% reduction in the composite cardiovascular (CV) outcome.

The results of QUARTET suggest that, “even in those with stage 1 hypertension, we can safely reduce BP to a significant degree by this simple approach, compared to usual care,” Salim Yusuf, MD, DPhil, a long-time advocate of a polypill approach, said in an email.

Importantly, Dr. Chow pointed out, at 12 months, 81% of patients treated with the quadpill versus 62% of patients treated with monotherapy had BP control (<140/90 mm Hg). Patients who received monotherapy did not “catch up,” even though a higher percentage received stepped-up therapy.

The quadpill dosing strategy aligns with the latest 2018 ESC/European Society of Hypertension guidelines, which recommend starting antihypertensive treatment with more than one drug, session cochair Thomas Kahan, MD, PhD, Karolinska Institute, Danderyd Hospital, department of clinical sciences, Stockholm, commented.

“How many drugs should be in the initial step?” he asked. “Is four better than three or two, or should we have even more drugs at low doses?”

The trial was not designed to answer these questions, Dr. Chow replied. “We were really comparing [the quadpill] against what the majority of people around the planet are still doing, which is starting on one drug and slowly but surely stepping it up,” she said.

The quadpill was actually a capsule, she clarified, that contained four generic BP medications available in half doses in Australia. The half doses were cut in half and the medications were encapsulated. The control drug was prepared in an identical-looking capsule.  

It is important to note that “the time to BP control was shorter in patients who received the quadpill versus monotherapy,” session cochair Felix Mahfoud, MD, internal medicine and cardiology, Saarland University Hospital, Hamburg, Germany, pointed out, because “in clinical practice we aim to get patients to BP control as quickly as possible.”

“What is new here is the use of four drugs, each given at quarter doses,” Dr. Yusuf, director of the Population Health Research Institute, McMaster University, Hamilton, Ont., said. Although a few questions remain, “this study emphasizes the importance and potential benefits and simplicity of using combination BP-lowering drugs at low doses.”

For guidelines to be changed, he observed, the findings would have to be replicated in independent studies, and the quadpill would likely have to be shown to be superior to the dual pill.

“It took about 20 years [to change guidelines] after the first evidence that combinations of two pills were preferable to single-drug combinations,” he noted.

“I hope that in most people with elevated BP, at least a two-drug combination plus a statin plus aspirin will be prescribed,” Dr. Yusuf said. “This can reduce the risk of CVD events by 50% or more – a big impact both for the individual and for populations. The quad pill may have a role in this approach.”
 

Four-in-one pill

Worldwide, hypertension control is poor, Dr. Chow said, because of the need for multiple medications, treatment inertia, and concerns about adverse events.

The researchers hypothesized that initial antihypertensive treatment with a four-in-one pill with quarter doses of each medication would minimize side effects, maximize BP lowering, and overcome these treatment barriers and concerns. A pilot study of this strategy published by the group in 2017 showed promise.

QUARTET randomized 591 adults with hypertension, seen at clinics in four states in Australia from June 2017 through August 2020.  

Patients were either receiving no antihypertensive medication and had an unattended standard office BP of 140/90 to 179/109 mm Hg or daytime ambulatory BP greater than 135/95 mm Hg, or they were on BP-lowering monotherapy and had a BP of 130/85 to 179/109 mm Hg or daytime ambulatory BP greater than 125/80 mm Hg. Patients who were taking antihypertensive therapy entered a washout period before the trial.

The researchers randomized 291 participants to receive 150 mg irbesartan daily (usual care or control group).

The other 300 participants received a daily quadpill containing 37.5 mg irbesartan, 1.25 mg amlodipine, 0.625 mg indapamide, and 2.5 mg bisoprolol. The first three drugs are the most commonly prescribed angiotensin II receptor blocker, calcium channel blocker, and thiazide or thiazidelike diuretic in Australia, and the last drug, a beta-blocker, has a long duration of action, the study protocol explains.

Patients in both groups had similar baseline characteristics. They were a mean age of 58 years, 40% were women, and 82% were White. They also had a mean body mass index of 31 kg/m². About 8% were current smokers, and about 54% were not taking a BP-lowering drug.

Participants had clinic visits at baseline, 6 weeks, and 12 weeks, and if they continued the study, at 26 weeks and 52 weeks.

If a patient’s blood pressure was higher than 140/90 mm Hg, clinicians could add another medication, starting with amlodipine 5 mg.

At 12 weeks, 15% of patients in the intervention group and 40% in the control group had stepped up treatment.

Despite greater up-titration in the usual care group, BP control remained higher in the quadpill group, Dr. Chow pointed out. That is, patients in the quadpill group were more likely than patients in the usual care group to have a BP less than 140/90 mm Hg (76% vs. 58% respectively; P < .0001).

Patients in the quadpill group also had lower daytime and nighttime ambulatory systolic BP.

At 12 months, among the 417 patients who continued treatment, patients in the quadpill group had a 7.7 mm Hg greater drop in systolic BP, compared with patients in the control group, (P < .001).  

There were no significant differences in adverse events, which were most commonly dizziness (31% and 25%) or muscle cramps, gastrointestinal complaints, headache, or musculoskeletal complaints.

At 12 weeks, there were seven serious adverse events in the intervention group versus three in the control group. There were 12 treatment withdrawals in the intervention group versus seven in the control group (P = .27).

Remaining questions, upcoming phase 3 U.S. study

“While the [QUARTET] results are impressive, we are left with a number of questions,” Dr. Yusuf said.

Would the results be the same with a three-drug combo or even a two-drug combo at half doses? In the HOPE 3 trial, a two-drug combo at half doses provided similar results to the current study, over a much longer mean follow-up of 5.6 years, he noted.

Also, is the quadpill associated with higher rates of diabetes or higher creatinine levels in the long term? “Given that we do not have any data on long-term clinical outcomes from a four-drug combination,” Dr. Yusuf said, “caution should be utilized.”

Would the reduced risk of CVD be greater with a combination of low doses of two BP-lowering drugs plus a statin plus aspirin? That may be superior, he said, “based on recent information published on the polypill indicating a 50% relative risk reduction in CVD events.”

The related phase 2 QUARTET US trial should shed further light on a quadpill strategy. Patients with hypertension are being randomized to a daily quadpill containing 2 mg candesartan, 1.25 mg amlodipine besylate, 0.625 mg indapamide, and 2.5 mg bisoprolol, or to usual care, 8 mg candesartan daily.

Investigators plan to enroll 87 participants in the Chicago area, with estimated study completion by March 31, 2023.

The study was supported by an Australian National Health and Medical Research Council grant. The George Institute for Global Health has submitted patent applications for low–fixed-dose combination products to treat CV or cardiometabolic disease. Dr. Chow and coauthor Kris Rogers, PhD, senior biostatistician at The George Institute for Global Health, Newtown, Australia, are listed as inventors, but they do not have direct financial interests in these patent applications.

Lung cancer disparities are reversible, but it will take changes at the social policy and organizational levels to do it, according to Ray Osarogiagbon, MBBS, a medical oncologist in the thoracic oncology program at Baptist Cancer Center, Memphis.

Much of the issue comes down to unequal distribution of services across the country, with less high-end care available in areas hardest hit by lung cancer, which are often areas with higher percentages of Black people, Dr. Osarogiagbon said. He addressed the issues – which he conceptualizes as “avoidable differences” – in a plenary presentation at the virtual 2021 World Conference on Lung Cancer.

He said that much of disparity research has focused on patient-level issues, but it has the least potential to effect change and also has “the unpleasant side effect of stigmatizing the victims of disparate health care delivery.”

Better to look at the big picture. “We have to focus on the areas where we are most likely to be successful, the social policy level, next the organizational level, and then providers,” he said.

Kentucky, followed by Mississippi, Arkansas, Tennessee, West Virginia, and Alabama, has the highest lung cancer burden in the United States. While lung cancer has been on the decline for decades nationwide, some counties in those states in particular continue to struggle with rising lung cancer mortality.

Dr. Osarogiagbon’s own health care system, which serves western Tennessee as well as eastern Arkansas and northern Mississippi, sees about 1,300 lung cancer cases annually, more than many states in the United States.

Regional disparities in lung cancer care span the entirety of available services, from unequal access to tobacco cessation and other preventive measures straight through to access to leading-edge systemic therapies. Disparities are particularly acute with more recent advances such as immunotherapy and low-dose CT screening.

One recent study, for instance, found that several southern states with high lung cancer burdens had screening rates below 4%, while several New England states had rates ranging to over 15%.

“There is a mismatch between the places were lung cancer kills and the places where we have invested in low-dose CT scan facilities,” Dr. Osarogiagbon said. As a side effect, White patients have better access,

It’s not, he said, that Black people are more likely to refuse such services, as least as far as clinical trials go.

Black patients are significantly underrepresented in pharmaceutical industry trials. Part of the issues is that areas hardest hit by lung cancer are often also ones less likely to have the infrastructure to support trials.

But on an equal playing field, Black patients are at least as eager as White patients to sign up for a trial. Dr. Osarogiagbon and colleagues found that, if offered the chance, almost 60% of Black patients said they would participate in a trial versus 53.4% of White patients. If access were equal, there would be “no race-based disparities” in trial participation, he said.

It’s also emerging that Black patients might benefit more from innovations such as immune checkpoint inhibitors treatment and low-dose CT screening, which means that, if they were included in more trials, companies would likely have stronger study results.

It’s something they should pay attention to, if for no other reason than it would help their bottom line, Dr. Osarogiagbon said.

Curative surgery for early-stage lung tumors is another issue. At the county level in the United States, he and his team found that it’s offered to anywhere from 13% to 92% of patients who qualify.

“Counties in the lowest quartile for receipt of surgery were those with a high proportion of non-Hispanic Black subjects, high poverty and uninsured rates, low surgeon-to-population ratio, and nonmetropolitan status,” they found.

Dr. Osarogiagbon is a consultant for and/or has stock in a number of companies, including AstraZeneca, Eli Lilly, and Genentech.

Regional disparities in lung cancer care span the entirety of available services, from unequal access to tobacco cessation and other preventive measures straight through to access to leading-edge systemic therapies. Disparities are particularly acute with more recent advances such as immunotherapy and low-dose CT screening.

One recent study, for instance, found that several southern states with high lung cancer burdens had screening rates below 4%, while several New England states had rates ranging to over 15%.

“There is a mismatch between the places were lung cancer kills and the places where we have invested in low-dose CT scan facilities,” Dr. Osarogiagbon said. As a side effect, White patients have better access,

It’s not, he said, that Black people are more likely to refuse such services, as least as far as clinical trials go.

Black patients are significantly underrepresented in pharmaceutical industry trials. Part of the issues is that areas hardest hit by lung cancer are often also ones less likely to have the infrastructure to support trials.

But on an equal playing field, Black patients are at least as eager as White patients to sign up for a trial. Dr. Osarogiagbon and colleagues found that, if offered the chance, almost 60% of Black patients said they would participate in a trial versus 53.4% of White patients. If access were equal, there would be “no race-based disparities” in trial participation, he said.

It’s also emerging that Black patients might benefit more from innovations such as immune checkpoint inhibitors treatment and low-dose CT screening, which means that, if they were included in more trials, companies would likely have stronger study results.

It’s something they should pay attention to, if for no other reason than it would help their bottom line, Dr. Osarogiagbon said.

Curative surgery for early-stage lung tumors is another issue. At the county level in the United States, he and his team found that it’s offered to anywhere from 13% to 92% of patients who qualify.

“Counties in the lowest quartile for receipt of surgery were those with a high proportion of non-Hispanic Black subjects, high poverty and uninsured rates, low surgeon-to-population ratio, and nonmetropolitan status,” they found.

Lung cancer disparities are reversible, but it will take changes at the social policy and organizational levels to do it, according to Ray Osarogiagbon, MBBS, a medical oncologist in the thoracic oncology program at Baptist Cancer Center, Memphis.

Much of the issue comes down to unequal distribution of services across the country, with less high-end care available in areas hardest hit by lung cancer, which are often areas with higher percentages of Black people, Dr. Osarogiagbon said. He addressed the issues – which he conceptualizes as “avoidable differences” – in a plenary presentation at the virtual 2021 World Conference on Lung Cancer.

He said that much of disparity research has focused on patient-level issues, but it has the least potential to effect change and also has “the unpleasant side effect of stigmatizing the victims of disparate health care delivery.”

Better to look at the big picture. “We have to focus on the areas where we are most likely to be successful, the social policy level, next the organizational level, and then providers,” he said.

Kentucky, followed by Mississippi, Arkansas, Tennessee, West Virginia, and Alabama, has the highest lung cancer burden in the United States. While lung cancer has been on the decline for decades nationwide, some counties in those states in particular continue to struggle with rising lung cancer mortality.

Investigators are zeroing in on the stage II-IIIa non–small cell lung cancer patients most likely to benefit from adjuvant atezolizumab (Tecentriq) following resection and chemotherapy.

It seems that PD-L1 positive patients, those who undergo lobectomy, those who have nodal involvement, and those treated with all common platinum doublets, with the possible exception of cisplatin-gemcitabine, are most likely to benefit from adjuvant treatment, according to a report at the virtual 2021 World Congress on Lung Cancer.

Results come for an analysis of IMpower010, which randomized 1,005 patients equally to either best supportive care or atezolizumab every 21 days for 16 cycles following resection and chemotherapy.

The topline results, reported recently, found a 34% improvement in disease-free survival (DFS) in stage II-IIIa patients expressing PD-L1 and a 21% improvement across all patients regardless of PD-L1 expression.

It was the first positive phase 3 trial for adjuvant immunotherapy in NSCLC. Maker Hoffman-La Roche subsequently applied to the U.S. Food and Drug Administration for an indication for adjuvant treatment following surgery and platinum-based chemotherapy for NSCLC with PD-L1 expression of at least 1%.

At the WCLC meeting, investigators took a closer look at IMpower010 to gauge the impact of different surgery and chemotherapy types on outcomes.

“Improved DFS was observed with adjuvant atezolizumab” for II-IIIa disease across most stages in patients “with nodal involvement, and across most surgery resection types and chemotherapy regimens,” said lead investigator Nasser Altorki, MD, director of the division of thoracic surgery at New York Presbyterian-Weill Cornell Medical Center in New York.

Study discussant Ichiro Yoshino, MD, PhD, a thoracic surgeon at Chiba University, in Japan, expanded on the “most” part of the assertion.

“Patients who underwent lobectomy [78%] had more evident benefit. … Patients who had a pneumonectomy [16%] did not benefit from atezolizumab,” he said (DFS hazard ratio, 0.91, 95% confidence interval, 0.56-1.47).

The reasons are unclear. It could be because patients who have pneumonectomies are less tolerant of adjuvant chemotherapy, so might have not gotten complete courses, but whatever the cause, Dr. Yoshino said it’s an important finding that needs further investigation.

Also, there was no DFS benefit in the 16% of patients who received cisplatin-gemcitabine for chemotherapy instead of other platinum doublets (HR, 0.94, 95% CI, 0.56-1.57).

It might have to do with the fact that under 80% of cisplatin-gemcitabine patients completed all four cycles of chemotherapy versus completion rates of up to more than 90% with other platinum doublets. It might also, however, have something to do with the way gemcitabine works or its interaction with atezolizumab.

The issue is another one that needs “to be examined,” Dr. Yoshino said.

The trial was funded by Hoffman-La Roche. Dr. Altorki is an advisor and/or researcher for AstraZeneca, Merck, and Johnson & Johnson. Among various company ties, Dr. Yoshino is an advisor and speaker for AstraZeneca and Johnson & Johnson and a researcher for Pfizer.

Lung cancer patients with relatively small nodules who cannot or will not undergo surgery or radiotherapy can be successfully treated with targeted transbronchial microwave ablation, indicate results from a U.K.-led preliminary trial.

The NAVABLATE study included 30 patients from the U.K. and Hong Kong who had malignant lung nodules no more than 30 mm in diameter, who underwent transbronchial microwave ablation and were followed up one month later.

On the day, the technique was performed successfully in all 30 patients, while follow-up imaging at one month suggested that the ablation had been satisfactory in every case, with no repeat procedures necessary.

It was also associated with a “low rate of device-related adverse events and no serious adverse events,” said lead author Kevin Lau, Barts Thorax Centre, St. Bartholomew’s Hospital, Barts Health NHS Trust, London.

Consequently, transbronchial microwave ablation can be considered “an alternative treatment modality for patients with primary and metastatic malignant lung nodules … who decline or are ineligible” for surgery and radiotherapy.

The research was presented at the European Respiratory Society International Congress (ERS) 2021 on September 5.
 

‘Encouraging’ results

Professor Stefano Elia, head of the European Respiratory Society’s Assembly on Thoracic Surgery and Transplantation, told this news organization that the results “are encouraging.”

However, the patient numbers are “very low, so it is difficult to draw value conclusions,” and he would like to have seen more detailed characterization of the patients’ tumors.

Prof. Elia, from the University of Rome Tor Vergata, added that transbronchial microwave ablation should, in line with the study’s inclusion criteria, “probably be reserved” for lung cancer patients “who are unfit for or refuse surgery or alternative treatment strategies.”

He added that “prospective, randomized trials are warranted to see if the technique is feasible, safe and indicated” in these patients, and the potential cost of performing it needs to be specified.
 

Study details

Presenting the study, Mr. Lau explained that NAVABLATE was a prospective, multicenter study that enrolled patients with a confirmed malignant lung nodule ≤30 mm that did not abut the pleura, fissure, or critical structures.

In addition, the patients had declined or were not eligible for both surgery and stereotactic body radiotherapy.

They underwent transbronchial microwave ablation with the Emprint ablation catheter (Medtronic) in a hybrid theatre while undergoing cone-beam computed tomography. Only one nodule was ablated if the patients had more than one.

The team recruited 30 patients at two centres in the U.K. and Hong Kong, who had a mean age of 68.4 years and of whom 40% were female. The majority (66.7%) were prior or current tobacco users.

Primary lung cancer was the diagnosis in 20 patients, while 10 had oligometastatic disease, and the median nodule size was 12.5 mm. Thirty percent of patients had previously undergone lobectomy and 16.7% wedge resection.

Thirty-nine ablations were performed in the 30 patients, with 22 having a single ablation. Two ablations were performed in seven patients, while one had three ablations.

The most common ablation times were 10 minutes, in 21 procedures, and 7 minutes, in eight procedures, and the average total bronchoscopy time was 127 minutes.
 

Technical success

The procedure was deemed a technical success, defined as the nodule being reached and ablated according to the study protocol, in all patients.

The average ablation margin was 9.9 mm, and 1-month follow-up imaging was performed in all patients. This revealed a satisfactory ablation in 100% of cases. No patients required retreatment.

One patient had an adverse event relating to the ablation itself over the one-month follow-up, consisting of grade 1 mild haemoptysis on day 5, which self-resolved.

Adverse events relating to any aspect of the bronchoscopy were seen in 70% of patients, while 13.3% had grade ≥3 events, These included post-procedure pleuritic chest pain in two patients, pleural effusion in two patients, post-ablation syndrome in one patient, and ablation site infection in one patient, all grade 3.

The researchers found that the patients reported only mild pain immediately post-procedure, at an average score of 1.5 on a 10-point scale, falling to 1.4 one week later. At one month, the average pain score was 0.5.

Quality of life, as measured on the EQ-5D-3L was unaffected by the procedure, with scores rising slightly from 74.6 at baseline to 77.4 at the one-month follow-up.

The study was sponsored and funded by Medtronic.

Mr. Lau declares relationships with Medtronic, Philips, and Johnson & Johnson.

Here’s some encouraging news for once regarding SARS-CoV-2 infections: A study of young adults for whom prepandemic spirometry data were available showed that COVID-19 did not have a significant impact on lung function, even among patients with asthma.

Among 853 Swedish men and women (mean age, 22 years) who were part of a birth cohort study, there were no significant differences in either forced expiratory volume in 1 second (FEV₁) or in the ratio of FEV1 to forced vital capacity, reported Ida Mogensen, MD, PhD, a postdoctoral fellow at the Karolinska Institute in Stockholm.

“We found no effect of COVID-19 on spirometric lung function in generally healthy adults,” she said in an oral abstract presented at the European Respiratory Society 2021 International Congress.

The findings echo those of a small study that involved 73 children and adolescents with COVID-19 and 45 uninfected control persons. The investigators in that study, which was also presented at ERS 2021, found that there were no significant differences in the frequency of abnormal pulmonary function measures between case patients and control patients (abstract OA1303).

“The findings from these two studies provide important reassurance about the impact of COVID infection on lung function in children and young adults,” commented Anita Simonds, MD, an honorary consultant in respiratory and sleep medicine at the Royal Brompton Hospital, London.

“We know already that this group is less likely to suffer severe illness if they contract the virus, and these studies, which importantly include comparator groups without COVID-19, show that they are also less likely to suffer long-term consequences with respect to lung function,” she said. Dr. Simonds was not involved in either study.
 

Young adult study

Dr. Mogenson and colleagues assessed data on 853 participants in the BAMSE Project, a prospective birth cohort study that included 4,089 children born in Stockholm from 1994 to 1996. Of the participants, 147 had asthma. They have been regularly followed with questionnaires on respiratory symptoms and medications. In addition, at 8 and 16 years’ follow-up, spirometry measures and fractional exhaled nitric oxide (FeNO) levels were assessed, allergic sensitization tests were administered, and blood eosinophil levels were measured.

In 2020 and 2021, during the pandemic, the participants underwent spirometry testing and were assessed for antibodies against SARS-CoV-2, and they self-reported use of inhaled corticosteroids.

The investigators defined asthma as any physician diagnosis and asthma symptoms and/or asthma medication use within the previous year. Participants were determined to be COVID-19 seropositive if they had IgG antibodies to the SARS-CoV-2 spike greater than 25.09 AU/mL, IgM antibodies greater than 14.42 AU/mL, or IgA antibodies greater than 2.61 AU/mL, as measured with enzyme-linked immunosorbent assay.

Participants who had been vaccinated against COVID-19 were excluded.
 

No significant decreases

A total of 243 participants, including 38 with asthma, were seropositive for SARS-CoV-2 antibodies. The mean change in lung function from before the pandemic to the study end date during the pandemic were not significantly different between seropositive participants and seronegative participants or IgM-positive participants and seronegative participants.

Similarly, there were no significant differences in lung function between seropositive and seronegative participants in an analysis that was adjusted for sex, body mass index, smoking status, or prepandemic lung function.

Although there was a trend toward slightly lower function among seropositive participants with asthma in comparison with seronegative patients with asthma, it was not statistically significant, Dr. Mogenson said.

There were also no significant decreases in lung function from the prepandemic measure to the present in any of the inflammatory parameters, including blood eosinophil levels, FeNO, allergic sensitization, or inhaled corticosteroid use.
 

Potential misclassification

In the question-and-answer period that followed the presentation, session comoderator Sam Bayat, MD, PhD, from the University of Grenoble (France), who was not involved in the study, noted that “some subjects can have positive serology without any symptoms, while others can have symptomatic disease and a couple of months later they have negative serology.”

He asked Dr. Mogenson whether they had included in their study participants with symptomatic COVID-19 and whether that would change the findings.

“We did not have access to RNA testing, so we only had serology, and of course some participants could be wrongly classified to have disease – probably around 15%,” she acknowledged.

She noted that there were no significant changes in lung function among patients who reported having respiratory symptoms.

The study was funded by the Swedish Research Council, the Swedish Heart-Lung Foundation, the Swedish Research Council for Health, Working Life and Welfare, the Karolinska Institutet, Formas, the European Research Council, and Region Stockholm. Dr. Mogenson, Dr. Simonds, and Dr. Bayat disclosed no relevant financial relationships.

Here’s some encouraging news for once regarding SARS-CoV-2 infections: A study of young adults for whom prepandemic spirometry data were available showed that COVID-19 did not have a significant impact on lung function, even among patients with asthma.

Among 853 Swedish men and women (mean age, 22 years) who were part of a birth cohort study, there were no significant differences in either forced expiratory volume in 1 second (FEV₁) or in the ratio of FEV1 to forced vital capacity, reported Ida Mogensen, MD, PhD, a postdoctoral fellow at the Karolinska Institute in Stockholm.

“We found no effect of COVID-19 on spirometric lung function in generally healthy adults,” she said in an oral abstract presented at the European Respiratory Society 2021 International Congress.

The findings echo those of a small study that involved 73 children and adolescents with COVID-19 and 45 uninfected control persons. The investigators in that study, which was also presented at ERS 2021, found that there were no significant differences in the frequency of abnormal pulmonary function measures between case patients and control patients (abstract OA1303).

“The findings from these two studies provide important reassurance about the impact of COVID infection on lung function in children and young adults,” commented Anita Simonds, MD, an honorary consultant in respiratory and sleep medicine at the Royal Brompton Hospital, London.

“We know already that this group is less likely to suffer severe illness if they contract the virus, and these studies, which importantly include comparator groups without COVID-19, show that they are also less likely to suffer long-term consequences with respect to lung function,” she said. Dr. Simonds was not involved in either study.
 

Young adult study

Dr. Mogenson and colleagues assessed data on 853 participants in the BAMSE Project, a prospective birth cohort study that included 4,089 children born in Stockholm from 1994 to 1996. Of the participants, 147 had asthma. They have been regularly followed with questionnaires on respiratory symptoms and medications. In addition, at 8 and 16 years’ follow-up, spirometry measures and fractional exhaled nitric oxide (FeNO) levels were assessed, allergic sensitization tests were administered, and blood eosinophil levels were measured.

In 2020 and 2021, during the pandemic, the participants underwent spirometry testing and were assessed for antibodies against SARS-CoV-2, and they self-reported use of inhaled corticosteroids.

The investigators defined asthma as any physician diagnosis and asthma symptoms and/or asthma medication use within the previous year. Participants were determined to be COVID-19 seropositive if they had IgG antibodies to the SARS-CoV-2 spike greater than 25.09 AU/mL, IgM antibodies greater than 14.42 AU/mL, or IgA antibodies greater than 2.61 AU/mL, as measured with enzyme-linked immunosorbent assay.

Participants who had been vaccinated against COVID-19 were excluded.
 

No significant decreases

A total of 243 participants, including 38 with asthma, were seropositive for SARS-CoV-2 antibodies. The mean change in lung function from before the pandemic to the study end date during the pandemic were not significantly different between seropositive participants and seronegative participants or IgM-positive participants and seronegative participants.

Similarly, there were no significant differences in lung function between seropositive and seronegative participants in an analysis that was adjusted for sex, body mass index, smoking status, or prepandemic lung function.

Although there was a trend toward slightly lower function among seropositive participants with asthma in comparison with seronegative patients with asthma, it was not statistically significant, Dr. Mogenson said.

There were also no significant decreases in lung function from the prepandemic measure to the present in any of the inflammatory parameters, including blood eosinophil levels, FeNO, allergic sensitization, or inhaled corticosteroid use.
 

Potential misclassification

In the question-and-answer period that followed the presentation, session comoderator Sam Bayat, MD, PhD, from the University of Grenoble (France), who was not involved in the study, noted that “some subjects can have positive serology without any symptoms, while others can have symptomatic disease and a couple of months later they have negative serology.”

He asked Dr. Mogenson whether they had included in their study participants with symptomatic COVID-19 and whether that would change the findings.

“We did not have access to RNA testing, so we only had serology, and of course some participants could be wrongly classified to have disease – probably around 15%,” she acknowledged.

Observational data indicate that the number of hospitalizations for cardiac arrests linked to opioid use roughly doubled from 2012 to 2018.

“This was an observational study, so we cannot conclude that all of the arrests were caused by opioids, but the findings do suggest the opioid epidemic is a contributor to increasing rates,” Senada S. Malik, of the University of New England, Portland, Maine, reported at the virtual annual congress of the European Society of Cardiology.

The data were drawn from the Nationwide Inpatient Sample (NIS) from 2012 to 2018, the most recent period available. Cardiac arrests were considered opioid related if there was a secondary diagnosis of opioid disease. The rates of opioid-associated hospitalizations for these types of cardiac arrests climbed from about 800 per year in 2012 to 1,500 per year in 2018, a trend that was statistically significant (P < .05).

The profile of patients with an opioid-associated cardiac arrest was different from those without secondary diagnosis of opioid disease. This included a younger age and lower rates of comorbidities: heart failure (21.2% vs. 40.6%; P < .05), renal failure (14.3% vs. 30.2%; P < .05), diabetes (19.5% vs. 35.4%; P < .05), and hypertension (43.4% vs. 64.9%; P < .05).
 

Mortality from opioid-associated cardiac arrest is lower

These features might explain the lower rate of in-hospital mortality for opioid-associated cardiac arrests (56.7% vs. 61.2%), according to Ms. Malik, who performed this research in collaboration with Wilbert S. Aronow, MD, director of cardiology research, Westchester Medical Center, Valhalla, N.Y.

When compared to those without a history of opioid use on admission, those with opioid-associated cardiac arrest were more likely to be depressed (18.8% vs. 9.0%), to smoke (37.0% vs. 21.8%) and to abuse alcohol (16.9% vs. 7.1%), according to the NIS data.

While these findings are based on cardiac arrests brought to a hospital, some opioid-induced cardiac arrests never result in hospital admission, according to data included in a recently issued scientific statement from the American Heart Association.

Rate of opioid-associated cardiac arrests underestimated

In that statement, which was focused on opioid-associated out-of-hospital cardiac arrests (OA-OHCA), numerous studies were cited to support the conclusion that these events are common and underestimated. One problem is that opioid-induced cardiac arrests are not always accurately differentiated from cardiac arrests induced by use of other substances, such as barbiturates, cocaine, or alcohol.

For this and other reasons, the data are inconsistent. One study based on emergency medical service (EMS) response data concluded that 9% of all out-of-hospital cardiac arrests are opioid associated.

In another study using potentially more accurate autopsy data, 60% of the non–cardiac-associated cardiac arrests were found to occur in individuals with potentially lethal serum concentrations of opioids. As 40% of out-of-hospital cardiac arrests were considered non–cardiac related, this suggested that 15% of all out-of-hospital cardiac arrests are opioid related.

In the NIS data, the incident curves of opioid-related cardiac arrests appeared to be flattening in 2018, the last year of data collection, but there was no indication they were declining.
 

Patterns of opioid-induced cardiac arrests evolving

The patterns of opioid-induced cardiac arrest have changed and are likely to continue to change in response to the evolving opioid epidemic, according to the AHA scientific statement. The authors described three waves of opioid abuse. The first, which was related to the promotion of prescription opioids to treat chronic pain that ultimately led to high rates of opioid addiction, peaked in 2012 when rates of these prescriptions began to fall. At that time a second wave, attributed to patients switching to less expensive nonprescription heroin, was already underway. A third wave, attributed to growth in the use of synthetic opioids, such as fentanyl, began in 2013 and is ongoing, according to data cited in the AHA statement.

Recognizing the role of opioids in rising rates of cardiac arrest is important for promoting strategies of effective treatment and prevention, according to Cameron Dezfulian, MD, medical director of the adult congenital heart disease program at Texas Children’s Hospital, Houston. Dr. Dezfulian was vice chair and leader of the writing committee for the AHA scientific statement on OA-OHCA. He said there are plenty of data to support the need for greater attention to the role of opioids in cardiac arrest.

“The recent data affirms the trends many of us have observed without our emergency rooms and ICUs: a steady increase in the proportion of OA-OHCA, primarily in young and otherwise healthy individuals,” he said.

He calls not only for more awareness at the front lines of health are but also for a more comprehensive approach.

“Public health policies and community- and hospital-based interventions are needed to reduce the mortality due to OA-OHCA, which is distinct from the traditional cardiac etiology,” Dr. Dezfulian said.

In opioid-induced cardiac arrest, as in other types of cardiac arrest, prompt initiation of cardiopulmonary resuscitation is essential, but early administration of the opioid antagonist naloxone can also be lifesaving, according to treatment strategies outlined in the AHA scientific statement. The fact that OA-OHCA typically occur in patients with structurally and electrophysiologically normal hearts is emphasized in the AHA statement. So is the enormous public health toll of OA-OHCA.

Death due to opioid overdose, which includes cardiac arrests, is now the leading cause of mortality in the U.S. among individuals between the ages of 25 and 64 years, according to the statement.

Ms. Malik reports no potential conflicts of interest. Dr. Dezfulian reports a financial relationship with Mallinckrodt.

One month of dual antiplatelet therapy followed by 11 months of clopidogrel monotherapy failed to prove noninferiority to 12 unbroken months of DAPT for net clinical benefit in a multicenter Japanese trial that randomized more than 4,000 patients who underwent percutaneous coronary intervention (PCI) after a recent acute coronary syndrome episode.

The outcomes showed that while truncating DAPT duration could, as expected, cut major bleeding episodes roughly in half, it also led to a significant near doubling of myocardial infarction and showed a strong trend toward also increasing a composite tally of several types of ischemic events. These data were reported this week by Hirotoshi Watanabe, MD, PhD, at the virtual annual congress of the European Society of Cardiology. All study patients had undergone PCI with cobalt-chromium everolimus-eluting (CCEE) coronary stents (Xience).

These findings from the STOPDAPT-2 ACS trial highlighted the limits of minimizing DAPT after PCI in patients at high ischemic risk, such as after an acute coronary syndrome (ACS) event.

It also was a counterpoint to a somewhat similar study also reported at the congress, MASTER DAPT, which showed that 1 month of DAPT was noninferior to 3 or more months of DAPT for net clinical benefit in a distinctly different population of patients undergoing PCI (and using a different type of coronary stent) – those at high bleeding risk and with only about half the patients having had a recent ACS.

The results of STOPDAPT-2 ACS “do not support use of 1 month of DAPT followed by P2Y12 inhibitor monotherapy with clopidogrel compared with standard DAPT,” commented Robert A. Byrne, MBBCh, PhD, designated discussant for the report and professor at the RCSI University of Medicine and Health Sciences in Dublin.

“Although major bleeding was significantly reduced with this approach, there appeared to be a significant increase in adverse ischemic events, and there was a clear signal in relation to overall mortality, the ultimate arbiter of net clinical benefit,” added Dr. Byrne, who is also director of cardiology at Mater Private Hospital in Dublin.

He suggested that a mechanistic explanation for the signal of harm seem in STOPDAPT-2 ACS was the relatively low potency of clopidogrel (Plavix) as an antiplatelet agent, compared with other P2Y12 inhibitors such as prasugrel (Effient) and ticagrelor (Brilinta), as well as the genetically driven variability in response to clopidogrel that’s also absent with alternative agents.

These between-agent differences are of “particular clinical relevance in the early aftermath of an ACS event,” Dr. Byrne said.
 

12-month DAPT remains standard for PCI patients with recent ACS

The totality of clinical evidence “continues to support a standard 12-month duration of DAPT – using aspirin and either prasugrel or ticagrelor – as the preferred default approach,” Dr. Byrne concluded.

He acknowledged that an abbreviated duration of DAPT followed by P2Y12 inhibitor monotherapy “might be considered as an alternative.” In patients following an ACS event who do not have high risk for bleeding, he said, the minimum duration of DAPT should be at least 3 months and with preferential use of a more potent P2Y12 inhibitor.

Twelve months of DAPT treatment with aspirin and a P2Y12 inhibitor for patients following PCI “remains the standard of care in guidelines,” noted Marco Roffi, MD, a second discussant at the congress. But several questions remain, he added, such as which P2Y12 inhibitors work best and whether DAPT can be less than 12 months.

“The investigators [for STOPDAPT-2 ACS] pushed these questions to the limit with 1 month of DAPT and clopidogrel monotherapy,” said Dr. Roffi, professor and director of interventional cardiology at University Hospital, Geneva.

“This was a risky bet, and the investigators lost by not proving noninferiority and with excess ischemic events,” he commented.
 

First came STOPDAPT-2

Dr. Watanabe and colleagues designed STOPDAPT-2 ACS as a follow-up to their prior STOPDAPT-2 trial, which randomly assigned slightly more than 3000 patients at 90 Japanese centers to the identical two treatment options: 1 month of DAPT followed by 11 months of clopidogrel monotherapy or 12 months of DAPT, except the trial enrolled all types of patients undergoing PCI. This meant that a minority, 38%, had a recent ACS event, while the remaining patients had chronic coronary artery disease. As in STOPDAPT-2 ACS, all patients in STOPDAPT-2 had received a CCEE stent.

STOPDAPT-2 also used the same primary endpoint to tally net clinical benefit as STOPDAPT-2 ACS: cardiovascular death, MI, stroke of any type, definite stent thrombosis, or TIMI major or minor bleeding classification.

In STOPDAPT-2, using the mixed population with both recent ACS and chronic coronary disease, the regimen of 1 month of DAPT followed by 11 months of clopidogrel monotherapy was both noninferior to and superior to 12 months of DAPT, reducing the net adverse-event tally by 36% relative to 12-month DAPT and by an absolute reduction of 1.34%, as reported in 2019.

Despite this superiority, the results from STOPDAPT-2 had little impact on global practice, commented Kurt Huber, MD, professor and director of the cardiology ICU at the Medical University of Vienna.

“STOP-DAPT-2 did not give us a clear message with respect to reducing antiplatelet treatment after 1 month. I thought that for ACS patients 1 month might be too short,” Dr. Huber said during a press briefing.
 

Focusing on post-ACS

To directly address this issue, the investigators launched STOPDAPT-2 ACS, which used the same design as the preceding study but only enrolled patients soon after an ACS event. The trial included for its main analysis 3,008 newly enrolled patients with recent ACS, and 1,161 patients who had a recent ACS event and had been randomly assigned in STOPDAPT-2, creating a total study cohort for the new analysis of 4136 patients treated and followed for the study’s full 12 months.

The patients averaged 67 years old, 79% were men, and 30% had diabetes. About 56% had a recent ST-elevation MI, about 20% a recent non–ST-elevation MI, and the remaining 24% had unstable angina. For their unspecified P2Y12 inhibition, roughly half the patients received clopidogrel and the rest received prasugrel. Adherence to the two assigned treatment regimens was very good, with a very small number of patients not adhering to their assigned protocol.

The composite adverse event incidence over 12 months was 3.2% among those who received 1-month DAPT and 2.83% in those on DAPT for 12 months, a difference that failed to achieve the prespecified definition of noninferiority for 1-month DAPT, reported Dr. Watanabe, an interventional cardiologist at Kyoto University.

The ischemic event composite was 50% lower among those on 12-month DAPT, compared with 1 month of DAPT, a difference that just missed significance. The rate of MI was 91% higher with 1-month DAPT, compared with 12 months, a significant difference.

One-month DAPT also significantly reduced the primary measure of bleeding events – the combination of TIMI major and minor bleeds – by a significant 54%, compared with 12-month DAPT. A second metric of clinically meaningful bleeds, those that meet either the type 3 or 5 definition of the Bleeding Academic Research Consortium, were reduced by a significant 59% by 1-month DAPT, compared with 12 months of DAPT.

The new findings from STOPDAPT-2 ACS contrasted with those from MASTER DAPT, but in an explicable way that related to different patient types, different P2Y12 inhibitors, different treatment durations, and different stents.

“We’ve seen in MASTER DAPT that if you use the right stent and use ticagrelor for monotherapy there may be some ability to shorten DAPT, but we still do not know what would happen in patients with very high ischemic risk,” concluded Dr. Huber.

“A reduction in DAPT duration might work in patients without high bleeding risk, but I would exclude patients with very high ischemic risk,” he added. “I also can’t tell you whether 1 month or 3 months is the right approach, and I think clopidogrel is not the right drug to use for monotherapy after ACS.”

STOPDAPT-2 and STOPDAPT-2 ACS were both sponsored by Abbott Vascular, which markets the CCEE (Xience) stents used in both studies. Dr. Watanabe has received lecture fees from Abbott and from Daiichi-Sankyo. Dr. Byrne has received research funding from Abbott Vascular as well as from Biosensors, Biotronik, and Boston Scientific.

One month of dual antiplatelet therapy followed by 11 months of clopidogrel monotherapy failed to prove noninferiority to 12 unbroken months of DAPT for net clinical benefit in a multicenter Japanese trial that randomized more than 4,000 patients who underwent percutaneous coronary intervention (PCI) after a recent acute coronary syndrome episode.

The outcomes showed that while truncating DAPT duration could, as expected, cut major bleeding episodes roughly in half, it also led to a significant near doubling of myocardial infarction and showed a strong trend toward also increasing a composite tally of several types of ischemic events. These data were reported this week by Hirotoshi Watanabe, MD, PhD, at the virtual annual congress of the European Society of Cardiology. All study patients had undergone PCI with cobalt-chromium everolimus-eluting (CCEE) coronary stents (Xience).

These findings from the STOPDAPT-2 ACS trial highlighted the limits of minimizing DAPT after PCI in patients at high ischemic risk, such as after an acute coronary syndrome (ACS) event.

It also was a counterpoint to a somewhat similar study also reported at the congress, MASTER DAPT, which showed that 1 month of DAPT was noninferior to 3 or more months of DAPT for net clinical benefit in a distinctly different population of patients undergoing PCI (and using a different type of coronary stent) – those at high bleeding risk and with only about half the patients having had a recent ACS.

The results of STOPDAPT-2 ACS “do not support use of 1 month of DAPT followed by P2Y12 inhibitor monotherapy with clopidogrel compared with standard DAPT,” commented Robert A. Byrne, MBBCh, PhD, designated discussant for the report and professor at the RCSI University of Medicine and Health Sciences in Dublin.

“Although major bleeding was significantly reduced with this approach, there appeared to be a significant increase in adverse ischemic events, and there was a clear signal in relation to overall mortality, the ultimate arbiter of net clinical benefit,” added Dr. Byrne, who is also director of cardiology at Mater Private Hospital in Dublin.

He suggested that a mechanistic explanation for the signal of harm seem in STOPDAPT-2 ACS was the relatively low potency of clopidogrel (Plavix) as an antiplatelet agent, compared with other P2Y12 inhibitors such as prasugrel (Effient) and ticagrelor (Brilinta), as well as the genetically driven variability in response to clopidogrel that’s also absent with alternative agents.

These between-agent differences are of “particular clinical relevance in the early aftermath of an ACS event,” Dr. Byrne said.
 

12-month DAPT remains standard for PCI patients with recent ACS

The totality of clinical evidence “continues to support a standard 12-month duration of DAPT – using aspirin and either prasugrel or ticagrelor – as the preferred default approach,” Dr. Byrne concluded.

He acknowledged that an abbreviated duration of DAPT followed by P2Y12 inhibitor monotherapy “might be considered as an alternative.” In patients following an ACS event who do not have high risk for bleeding, he said, the minimum duration of DAPT should be at least 3 months and with preferential use of a more potent P2Y12 inhibitor.

Twelve months of DAPT treatment with aspirin and a P2Y12 inhibitor for patients following PCI “remains the standard of care in guidelines,” noted Marco Roffi, MD, a second discussant at the congress. But several questions remain, he added, such as which P2Y12 inhibitors work best and whether DAPT can be less than 12 months.

“The investigators [for STOPDAPT-2 ACS] pushed these questions to the limit with 1 month of DAPT and clopidogrel monotherapy,” said Dr. Roffi, professor and director of interventional cardiology at University Hospital, Geneva.

“This was a risky bet, and the investigators lost by not proving noninferiority and with excess ischemic events,” he commented.
 

First came STOPDAPT-2

Dr. Watanabe and colleagues designed STOPDAPT-2 ACS as a follow-up to their prior STOPDAPT-2 trial, which randomly assigned slightly more than 3000 patients at 90 Japanese centers to the identical two treatment options: 1 month of DAPT followed by 11 months of clopidogrel monotherapy or 12 months of DAPT, except the trial enrolled all types of patients undergoing PCI. This meant that a minority, 38%, had a recent ACS event, while the remaining patients had chronic coronary artery disease. As in STOPDAPT-2 ACS, all patients in STOPDAPT-2 had received a CCEE stent.

STOPDAPT-2 also used the same primary endpoint to tally net clinical benefit as STOPDAPT-2 ACS: cardiovascular death, MI, stroke of any type, definite stent thrombosis, or TIMI major or minor bleeding classification.

In STOPDAPT-2, using the mixed population with both recent ACS and chronic coronary disease, the regimen of 1 month of DAPT followed by 11 months of clopidogrel monotherapy was both noninferior to and superior to 12 months of DAPT, reducing the net adverse-event tally by 36% relative to 12-month DAPT and by an absolute reduction of 1.34%, as reported in 2019.

Despite this superiority, the results from STOPDAPT-2 had little impact on global practice, commented Kurt Huber, MD, professor and director of the cardiology ICU at the Medical University of Vienna.

“STOP-DAPT-2 did not give us a clear message with respect to reducing antiplatelet treatment after 1 month. I thought that for ACS patients 1 month might be too short,” Dr. Huber said during a press briefing.
 

Focusing on post-ACS

To directly address this issue, the investigators launched STOPDAPT-2 ACS, which used the same design as the preceding study but only enrolled patients soon after an ACS event. The trial included for its main analysis 3,008 newly enrolled patients with recent ACS, and 1,161 patients who had a recent ACS event and had been randomly assigned in STOPDAPT-2, creating a total study cohort for the new analysis of 4136 patients treated and followed for the study’s full 12 months.

The patients averaged 67 years old, 79% were men, and 30% had diabetes. About 56% had a recent ST-elevation MI, about 20% a recent non–ST-elevation MI, and the remaining 24% had unstable angina. For their unspecified P2Y12 inhibition, roughly half the patients received clopidogrel and the rest received prasugrel. Adherence to the two assigned treatment regimens was very good, with a very small number of patients not adhering to their assigned protocol.

The composite adverse event incidence over 12 months was 3.2% among those who received 1-month DAPT and 2.83% in those on DAPT for 12 months, a difference that failed to achieve the prespecified definition of noninferiority for 1-month DAPT, reported Dr. Watanabe, an interventional cardiologist at Kyoto University.

One-month DAPT also significantly reduced the primary measure of bleeding events – the combination of TIMI major and minor bleeds – by a significant 54%, compared with 12-month DAPT. A second metric of clinically meaningful bleeds, those that meet either the type 3 or 5 definition of the Bleeding Academic Research Consortium, were reduced by a significant 59% by 1-month DAPT, compared with 12 months of DAPT.

“All physicians, regardless of specialty, will work with patients with disabilities,” Corrie Harris, MD, of the University of Louisville (Ky.), said in a plenary session presentation at the 2021 virtual Pediatric Hospital Medicine conference.

Disabilities vary in their visibility, from cognitive and sensory impairments that are not immediately obvious to an obvious physical disability, she said.

One in four adults and one in six children in the United States has a disability, said Dr. Harris. The prevalence of disability increases with age, but occurs across the lifespan, and will likely increase in the future with greater improvements in health care overall.

Dr. Harris reviewed the current conceptual model that forms the basis for the World Health Organization definition of functioning disability. This “functional model” defines disability as caused by interactions between health conditions and the environment, and the response is to “prioritize function to meet patient goals,” Dr. Harris said at the meeting, sponsored by the Society of Hospital Medicine, the American Academy of Pediatrics, and the Academic Pediatric Association.

This model is based on collaboration between health care providers and their patients with disabilities, and training is important to help providers make this collaboration successful, said Dr. Harris. Without training, physicians may be ineffective in communicating with patients with disabilities by not speaking directly to the patient, not speaking in a way the patient can understand clearly, and not providing accessible patient education materials. Physicians also tend to minimize the extent of the patient’s expertise in their own condition based on their lived experiences, and tend to underestimate the abilities of patients with disabilities.

However, direct experience with disabled patients and an understanding of the health disparities they endure can help physicians look at these patients “through a more intersectional lens,” that also takes into account social determinants of health, Dr. Harris said. “I have found that people with disabilities are the best teachers about disability, because they have expertise that comes from their lived experience.”
 

Patients are the best teachers

Several initiatives are helping physicians to bridge this gap in understanding and reduce disparities in care. One such program is FRAME: Faces Redefining the Art of Medical Education. FRAME is a web-based film library designed to present medical information to health care providers in training, clinicians, families, and communities in a dignified and humanizing way. FRAME was developed in part by fashion photographer Rick Guidotti, who was inspired after meeting a young woman with albinism to create Positive Exposure, an ongoing project featuring children and adolescents with various disabilities.

FRAME films are “short films presenting all the basic hallmark characteristics of a certain genetic condition, but presented by somebody living with that condition,” said Mr. Guidotti in his presentation during the session.

The National Curriculum Initiative in Developmental Medicine (NCIDM) is designed to incorporate care for individuals with disabilities into medical education. NCIDM is a project created by the American Academy of Developmental Medicine and Dentistry (AADMD).

“The need for this program is that there is no U.S. requirement for medical schools to teach about intellectual and developmental disabilities,” Priya Chandan, MD, also of the University of Louisville, said in her presentation during the session. “Approximately 81% of graduating medical students have no training in caring for adults with disabilities,” said Dr. Chandan, who serves as director of the NCIDM.

The current NCIDM was created as a 5-year partnership between the AADMD and Special Olympics, supported in part by the Centers for Disease Control and Prevention, Dr. Chandan said. The purpose was to provide training to medical students in the field of developmental medicine, meaning the care of individuals with intellectual/developmental disabilities (IDD) across the lifespan. The AADMD has expanded to 26 medical schools in the United States and will reach approximately 4,000 medical students by the conclusion of the current initiative.

One challenge in medical education is getting past the idea that people living with disabilities need to be fixed, said Dr. Chandan. The NCIDM approach reflects Mr. Guidotti’s approach in both the FRAME initiatives and his Positive Exposure foundation, with a focus on treating people as people, and letting individuals with disabilities represent themselves.

Dr. Chandan described the NCIDM curriculum as allowing for flexible teaching methodologies and materials, as long as they meet the NCIDM-created learning goals and objectives. The curriculum also includes standardized evaluations. Each NCIDM program in a participating medical school includes a faculty champion, and the curriculum supports meeting people with IDD not only inside medical settings, but also outside in the community.

NCIDM embraces the idea of community-engaged scholarship, which Dr. Chandan defined as “a form of scholarship that directly benefits the community and is consistent with university and unit missions.” This method combined teaching and conducting research while providing a service to the community.

The next steps for the current NCIDM initiative are to complete collection of data and course evaluations from participating schools by early 2022, followed by continued dissemination and collaboration through AADMD.

Overall, the content of the curriculum explores how and where IDD fits into clinical care, Dr. Chandan said, who also emphasized the implications of communication. “How we think affects how we communicate,” she added. Be mindful of the language used to talk to and about patients with disabilities, both to colleagues and to learners.

When talking to the patient, find something in common, beyond the diagnosis, said Dr. Chandan. Remember that some disabilities are visible and some are not. “Treat people with respect, because you won’t know what their functional level is just by looking,” she concluded.

The presenters had no financial conflicts to disclose.

The AADMD has expanded to 26 medical schools in the United States and will reach approximately 4,000 medical students by the conclusion of the current initiative.

One challenge in medical education is getting past the idea that people living with disabilities need to be fixed, said Dr. Chandan. The NCIDM approach reflects Mr. Guidotti’s approach in both the FRAME initiatives and his Positive Exposure foundation, with a focus on treating people as people, and letting individuals with disabilities represent themselves.

Dr. Chandan described the NCIDM curriculum as allowing for flexible teaching methodologies and materials, as long as they meet the NCIDM-created learning goals and objectives. The curriculum also includes standardized evaluations. Each NCIDM program in a participating medical school includes a faculty champion, and the curriculum supports meeting people with IDD not only inside medical settings, but also outside in the community.

NCIDM embraces the idea of community-engaged scholarship, which Dr. Chandan defined as “a form of scholarship that directly benefits the community and is consistent with university and unit missions.” This method combined teaching and conducting research while providing a service to the community.

The next steps for the current NCIDM initiative are to complete collection of data and course evaluations from participating schools by early 2022, followed by continued dissemination and collaboration through AADMD.

Overall, the content of the curriculum explores how and where IDD fits into clinical care, Dr. Chandan said, who also emphasized the implications of communication. “How we think affects how we communicate,” she added. Be mindful of the language used to talk to and about patients with disabilities, both to colleagues and to learners.

When talking to the patient, find something in common, beyond the diagnosis, said Dr. Chandan. Remember that some disabilities are visible and some are not. “Treat people with respect, because you won’t know what their functional level is just by looking,” she concluded.

The presenters had no financial conflicts to disclose.

New European guidelines for the management of valvular heart disease offer more than 45 revised or completely new recommendations relative to the previous version published in 2017, according to members of the writing committee who presented the changes during the annual congress of the European Society of Cardiology.

With their emphasis on early diagnosis and expansion of indications, these 2021 ESC/European Association for Cardio-Thoracic Surgery guidelines are likely to further accelerate the already steep growth in this area of interventional cardiology, according to Alec Vahanian, MD, a professor of cardiology at the University of Paris.

“Valvular heart disease is too often undetected, and these guidelines stress the importance of clinical examination and the best strategies for diagnosis as well as treatment,” he said.

Of the multiple sections and subsections, which follow the same format of the previous guidelines, the greatest number of revisions and new additions involve perioperative antithrombotic therapy, according to the document, which was published in conjunction with the ESC Congress.
 

Eleven new guidelines for anticoagulants

On the basis of evidence published since the previous guidelines, there are 11 completely new recommendations regarding the use of anticoagulants or antiplatelet therapies. The majority of these have received a grade I indication, which signifies “recommended” or “indicated.” These include indications for stopping or starting anticoagulants and which anticoagulants or antiplatelet drugs to consider in specific patient populations.

The next most common focus of new or revised recommendations involves when to consider surgical aortic valve repair (SAVR) relative to transcatheter aortic valve implantation (TAVI) in severe aortic stenosis. Most of these represent revisions from the previous guidelines, but almost all are also grade I recommendations.

“SAVR and TAVI are both excellent options in appropriate patients, but they are not interchangeable,” explained Bernard D. Prendergast, BMedSci, MD, director of the cardiac structural intervention program, Guy’s and St Thomas’ Hospital, London.

While the previous guidelines generally reserved TAVI for those not suitable for SAVR, the new guidelines are more nuanced.

As a rule, SAVR is generally preferred for younger patients. The reason, according to Dr. Prendergast, is concern that younger patients might outlive the expected lifespan of the prosthetic TAVI device.

No single criterion for selecting SAVR over TAVI

However, there are many exceptions and additional considerations beyond age. When both SAVR and TAVI are otherwise suitable options, but TAVI cannot be performed with a transfemoral access, Dr. Prendergast pointed out that SAVR might be a better choice.

Transfemoral access is the preferred strategy in TAVI, but Dr. Prendergast emphasized that a collaborative “heart team” should help patients select the most appropriate option. In fact, there is a grade IIb recommendation (“usefulness or efficacy is less well established”) to consider other access sites in patients at high surgical risk with contraindications for transfemoral TAVI.

Of new recommendations in the area of severe aortic stenosis, valvular repair may now be considered in asymptomatic patients with a left ventricular ejection fraction of less than 55%, according to a grade IIb recommendation. The 2017 guidelines did not address this issue.
 

Grade I recommendation for bioprostheses

A substantial number of the revisions involve minor clarifications without a change in the grade, but a revision regarding bioprosthetics is substantial. In the 2017 guidelines, there was a grade IIa recommendation (“weight of evidence is in favor”) to consider bioprosthetics in patients with a life expectancy less than the expected durability of the device. The 2021 guidelines have changed this to a grade I indication, adding an indication for bioprostheses in patients contraindicated for or unlikely to achieve good-quality anticoagulation.

On this same topic, there is a new grade IIb recommendation to consider bioprosthesis over alternative devices in patients already on a long-term non–vitamin K oral anticoagulant because of the high risk of thromboembolism.

University of Bern

There are two new recommendations in the realm of severe secondary mitral regurgitation, reported Fabien Praz, MD, an interventional cardiologist at the University of Bern (Switzerland). The first, which is perhaps the most significant, is a grade I recommendation for valve surgery in patients with severe secondary mitral regurgitation who remain symptomatic despite optimized medical therapy.

The second is a grade IIa recommendation for invasive procedures, such as a percutaneous coronary intervention, for patients with symptomatic secondary mitral regurgitation and coexisting coronary artery disease. In both cases, however, Dr. Praz emphasized language in the guidelines that calls for a collaborative heart team to agree on the suitability of these treatments.

Ultimately, none of these recommendations can be divorced from patient expectations and values, according to Friedhelm Beyersdorf, MD, chairman of the department of cardiovascular surgery at the Heart Center of the University of Freiburg (Germany).

Even if treatment is not expected to prolong life, “symptom relief on its own may justify intervention,” said Dr. Beyersdorf. However, he emphasized that “thoroughly informed” patients are an essential part of the process in selecting a treatment strategy most likely to satisfy patient goals.

Dr. Vahanian and Dr. Prendergast reported no conflicts of interest relevant to these guidelines. Dr. Praz reported a financial relationship with Edwards Lifesciences. Dr. Beyersdorf reported a financial relationship with Resuscitec.

“Health care spending and health care waste is a huge problem in the U.S., including for children,” Vivian Lee, MD, of Children’s Hospital, Los Angeles, said in a presentation at the 2021 virtual Pediatric Hospital Medicine conference.

Data from a 2019 study suggested that approximately 25% of health care spending in the United States qualifies as “wasteful spending,” in categories such as overtesting, and unnecessary hospitalization, Dr. Lee said. “It is essential for physicians in hospitals to be stewards of high-value care,” she emphasized.

To combat wasteful spending and control health care costs, the Choosing Wisely campaign was created in 2012 as an initiative from the American Board of Internal Medicine Foundation. An ongoing goal of the campaign is to raise awareness among physicians and patients about potential areas of low-value services and overuse. The overall campaign includes clinician-driven recommendations from multiple medical organizations.

The PHM produced its first set of five recommendations in 2012, Dr. Lee said. These recommendations, titled “Five Things Physicians and Patients Should Question,” have been updated for 2021. The updated recommendations were created as a partnership among the Academic Pediatric Association, the American Academy of Pediatrics, and the Society of Hospital Medicine. A joint committee reviewed the latest evidence, and the updates were approved by the societies and published by the ABIM in January 2021.

“We think these recommendations truly reflect an exciting and evolving landscape for pediatric hospitalists,” Dr. Lee said. “There is a greater focus on opportunities to transition out of the hospital sooner, or avoid hospitalization altogether. There is an emphasis on antibiotic stewardship and a growing recognition of the impact that overuse may have on our vulnerable neonatal population,” she said. Several members of the Choosing Wisely panel presented the recommendations during the virtual presentation.
 

Revised recommendations

The new “Five Things Physicians and Patients Should Question” are as follows:

1. Do not prescribe IV antibiotics for predetermined durations for patients hospitalized with infections such as pyelonephritis, osteomyelitis, and complicated pneumonia. Consider early transition to oral antibiotics.

Many antibiotic doses used in clinical practice are preset durations that are not based on high-quality evidence, said Mike Tchou, MD, of Children’s Hospital of Colorado in Aurora. However, studies now show that earlier transition to enteral antibiotics can improve a range of outcomes including neonatal UTIs, osteomyelitis, and complicated pneumonia, he said. Considering early transition based on a patient’s response can decrease adverse events, pain, length of stay, and health care costs, he explained.

2. Do not continue hospitalization in well-appearing febrile infants once bacterial cultures (i.e., blood, cerebrospinal, and/or urine) have been confirmed negative for 24-36 hours, if adequate outpatient follow-up can be assured.

Recent data indicate that continuing hospitalization beyond 24-36 hours of confirmed negative bacterial cultures does not improve clinical outcomes for well-appearing infants admitted for concern of serious bacterial infection, said Paula Soung, MD, of Children’s Wisconsin in Milwaukee. In fact, “blood culture yield is highest in the first 12-36 hours after incubation with multiple studies demonstrating > 90% of pathogen cultures being positive by 24 hours,” Dr. Soung said. “If adequate outpatient follow-up can be assured, discharging well-appearing febrile infants at 24-36 hours after confirming cultures are negative has many positive outcomes,” she said.

3. Do not initiate phototherapy in term or late preterm well-appearing infants with neonatal hyperbilirubinemia if their bilirubin is below levels at which the AAP guidelines recommend treatment.

In making this recommendation, “we considered that the risk of kernicterus and cerebral palsy is extremely low in otherwise healthy term and late preterm newborns,” said Allison Holmes, MD, of Children’s Hospital at Dartmouth-Hitchcock, Manchester, N.H. “Subthreshold phototherapy leads to unnecessary hospitalization and its associated costs and harms,” and data show that kernicterus generally occurs close to 40 mg/dL and occurs most often in infants with hemolysis, she added.

The evidence for the recommendations included data showing that, among other factors, 8.6 of 100,000 babies have a bilirubin greater than 30 mg/dL, said Dr. Holmes. Risks of using subthreshold phototherapy include increased length of stay, increased readmissions, and increased costs, as well as decreased breastfeeding, bonding with parents, and increased parental anxiety. “Adding prolonged hospitalization for an intervention that might not be necessary can be stressful for parents,” she said.

4. Do not use broad-spectrum antibiotics such as ceftriaxone for children hospitalized with uncomplicated community-acquired pneumonia. Use narrow-spectrum antibiotics such as penicillin, ampicillin, or amoxicillin.

Michelle Lossius, MD, of the Shands Hospital for Children at the University of Florida, Gainesville, noted that the recommendations reflect IDSA guidelines from 2011 advising the use of ampicillin or penicillin for this population of children. More recent studies with large populations support the ability of narrow-spectrum antibiotics to limit the development of resistant organisms while achieving the same or better outcomes for children hospitalized with CAP, she said.

5. Do not start IV antibiotic therapy on well-appearing newborn infants with isolated risk factors for sepsis such as maternal chorioamnionitis, prolonged rupture of membranes, or untreated group-B streptococcal colonization. Use clinical tools such as an evidence-based sepsis risk calculator to guide management.

“This recommendation combines other recommendations,” said Prabi Rajbhandari, MD, of Akron (Ohio) Children’s Hospital. The evidence is ample, as the Centers for Disease Control and Prevention recommends the use of sepsis calculators to guide clinical management in sepsis patients, she said.

Data comparing periods before and after the adoption of a sepsis risk calculator showed a significant reduction in the use of blood cultures and antibiotics, she noted. Other risks of jumping to IV antibiotics include increased hospital stay, increased parental anxiety, and decreased parental bonding, Dr. Rajbhandari added.

Next steps include how to prioritize implementation, as well as deimplementation of outdated practices, said Francisco Alvarez, MD, of Lucile Packard Children’s Hospital, Palo Alto, Calif. “A lot of our practices were started without good evidence for why they should be done,” he said. Other steps include value improvement research; use of dashboards and benchmarking; involving other stakeholders including patients, families, and other health care providers; and addressing racial disparities, he concluded.

The presenters had no financial conflicts to disclose. The conference was sponsored by the Academic Pediatric Association, the American Academy of Pediatrics, and the Society of Hospital Medicine.

Do not start IV antibiotic therapy on well-appearing newborn infants with isolated risk factors for sepsis such as maternal chorioamnionitis, prolonged rupture of membranes, or untreated group-B streptococcal colonization. Use clinical tools such as an evidence-based sepsis risk calculator to guide management.

“This recommendation combines other recommendations,” said Prabi Rajbhandari, MD, of Akron (Ohio) Children’s Hospital. The evidence is ample, as the Centers for Disease Control and Prevention recommends the use of sepsis calculators to guide clinical management in sepsis patients, she said.

Data comparing periods before and after the adoption of a sepsis risk calculator showed a significant reduction in the use of blood cultures and antibiotics, she noted. Other risks of jumping to IV antibiotics include increased hospital stay, increased parental anxiety, and decreased parental bonding, Dr. Rajbhandari added.

Next steps include how to prioritize implementation, as well as deimplementation of outdated practices, said Francisco Alvarez, MD, of Lucile Packard Children’s Hospital, Palo Alto, Calif. “A lot of our practices were started without good evidence for why they should be done,” he said. Other steps include value improvement research; use of dashboards and benchmarking; involving other stakeholders including patients, families, and other health care providers; and addressing racial disparities, he concluded.
