The Centers for Disease Control and Prevention is warning of an early surge in respiratory disease caused by multiple viruses. As influenza viruses, respiratory syncytial virus (RSV), SARS-CoV-2, and rhinovirus/enterovirus simultaneously circulate, the agency cautioned that this confluence of viral activity could strain the health care system, according to a CDC Health Network Alert advisory issued Nov. 4.

“This early increase in disease incidence highlights the importance of optimizing respiratory virus prevention and treatment measures, including prompt vaccination and antiviral treatment,” the alert stated.

The CDC reports that RSV activity is increasing nationally, but in some areas – such as the South and Mountain West – cases appear to be trending downward.

Influenza cases continue to climb, with the virus activity being the highest in the South, Mid-Atlantic, and the south-central West Coast, according to CDC data. “In fact, we’re seeing the highest influenza hospitalization rates going back a decade,” said José Romero, MD, director of the CDC’s National Center for Immunization and Respiratory Diseases, during a press briefing. The agency estimates that there have been 1.6 million illnesses, 13,000 hospitalizations, and 730 deaths from the flu so far this season. As of Nov. 4, there have been two pediatric deaths.

COVID-19 cases appear to have plateaued in the past three weeks, Dr. Romero said; however, the CDC expects that there will be “high-level circulation of SARS-CoV-2 this fall and winter,” the health alert stated.

The CDC advised that all eligible individuals aged 6-months or older should be vaccinated against COVID-19 and influenza. To protect against RSV-hospitalization, high-risk children should receive the monoclonal antibody drug palivizumab (Synagis). High-risk children include infants born before 29 weeks, children younger than age 2 with chronic lung disease or hemodynamically significant congenital heart disease, and children with suppressed immune systems or neuromuscular disorders.

Any patient with confirmed or suspected flu who is hospitalized, at higher risk for influenza complications, or who has a severe or progressive illness should be treated as early as possible with antivirals, such as oral oseltamivir (Tamiflu).

Patients with confirmed SARS-CoV-2 infection with increased risk of complications should also be treated with antivirals, such as nirmatrelvir and ritonavir (Paxlovid) or remdesivir (Veklury).

Patients should also be reminded to wash their hands frequently, cover coughs and sneezes, stay home when sick, and avoid close contact with people who are sick, the CDC advised.

“There’s no doubt that we will face some challenges this winter,” said Dawn O’Connell, HHS Assistant Secretary for Preparedness and Response, “but it’s important to remember that RSV and flu are not new, and we have safe and effective vaccines for COVID-19 and the flu.”

A man in England who was infected with an early strain of COVID-19 was finally cleared 411 days after first testing positive, according to experts in the United Kingdom. 

The man was treated with a mixture of neutralizing monoclonal antibodies, King’s College London said in a news release.

The man, 59, tested positive in December 2020 and tested negative in January 2022. He had a weakened immune system because of a previous kidney transplant. He received three doses of vaccine and his symptoms lessened, but he kept testing positive for COVID.

To find out if the man had a persistent infection or had been infected several times, doctors did a genetic analysis of the virus.

“This revealed that the patient’s infection was a persistent infection with an early COVID variant – a variation of the original Wuhan variant that was dominant in the United Kingdom in the later months of 2020. Analysis found the patient’s virus had multiple mutations since he was first infected,” King’s College said.

The doctors treated him with a Regeneron treatment that is no longer widely used because it’s not effective against newer COVID variants.

“Some new variants of the virus are resistant to all the antibody treatments available in the United Kingdom and Europe. Some people with weakened immune systems are still at risk of severe illness and becoming persistently infected. We are still working to understand the best way to protect and treat them,” Luke Snell, MD, from the King’s College School of Immunology & Microbial Sciences, said in the news release.

This is one of the longest known cases of COVID infection. Another man in England was infected with COVID for 505 days before his death, which King’s College said was the longest known COVID infection.

The COVID-19 bivalent Pfizer/BioNTech vaccine triggers a stronger immune response than a fourth dose of the original vaccine, the company reported on Nov. 4, supporting calls by public health officials for eligible people to get this booster before a potential COVID-19 surge this winter.

The company’s ongoing phase 2/3 study of their Omicron BA.4 and BA.5 bivalent – which targets both the virus’ original strain and the two subvariants – shows that the vaccine offered the strongest protection in people older than 55 years.

One month after receiving a 30-mcg booster with the bivalent vaccine, those older than 55 had four times more neutralizing antibodies against these Omicron subvariants, compared with people who received the original monovalent vaccine as a booster in the study.

Researchers compared the geometric mean titer (GMT) levels of these antibodies in three groups before and 1 month after boosting. The 36 people older than 55 years in the released study findings had an GMT level of 896 with the bivalent booster, a level 13 times higher than before this immunization.

For the 38 adults ages 18-55 in the study, the GMT level increased to 606 at 1 month after the bivalent booster, an increase of almost 10-fold, compared with baseline. In a comparator group of 40 people receiving the original vaccine as a fourth dose, the GMT level was 236, or threefold higher than before their booster shot.

The newly released data is “very encouraging and consistent now with three studies all showing a substantial 3-4 fold increased level of neutralizing antibodies versus BA.5 as compared with the original booster,” said Eric Topol, MD, director of the Scripps Research Translational Institute in La Jolla, Calif., and editor-in-chief of Medscape Medical News.

Pfizer and BioNTech announced the updated findings in a Nov. 4 press release.

A booster dose of the BA.4/BA.5-adapted bivalent vaccine is authorized for emergency use by the Food and Drug Administration for ages 5 years and older. The safety and tolerability profile of the Pfizer/BioNTech bivalent booster remains favorable and similar to the original COVID-19 vaccine, the company reported.

Until recently, the BA.5 Omicron variant was the dominant strain in the United States, but is now getting elbowed out by the subvariants BQ.1.1, BQ.1, and BA.4.6, which together make up almost 45% of the circulating virus.
 

Some skepticism

“It is important to note that these data are press-release level, which does not allow a view of the data totality,” Hana El Sahly, MD, professor of molecular virology and microbiology, Baylor College of Medicine, Houston, said in an interview.

“For example, there may be significant differences between the groups, and the release mentions at least one difference that is of importance: the interval since the last vaccination which often affects the response to subsequent boosting,” she said.

Dr. El Sahly added that the findings are not surprising. “In the short term, a variant-specific vaccine produces a higher level of antibody against the variant in the vaccine than the vaccines based on the ancestral strains.”

More researcher results are warranted. “These data do not indicate that these differences between the two vaccines translate into a meaningful clinical benefit at a population level,” Dr. El Sahly said.
 

An uncertain winter ahead

“As we head into the holiday season, we hope these updated data will encourage people to seek out a COVID-19 bivalent booster as soon as they are eligible in order to maintain high levels of protection against the widely circulating Omicron BA.4 and BA.5 sublineages,” Albert Bourla, Pfizer chairman and CEO, stated in the release.

The updated data from the Pfizer/BioNTech study are “all the more reason to get a booster, with added protection also versus BQ.1.1, which will soon become dominant in the U.S.,” Dr. Topol predicted.

It is unclear when the next surge will happen, as COVID-19 does not always follow a seasonal pattern, at least not yet, Dr. El Sahly said. “Regardless, it is reasonable to recommend additional vaccine doses to immunocompromised and frail or older persons. More importantly, influenza vaccination and being up to date on pneumococcal vaccines are highly recommended as soon as feasible, given the early and intense flu season.”

CHICAGO – Routine early, expeditious use of extracorporeal membrane oxygenation (ECMO) is a common strategy in patients with severe cardiogenic shock, but a less aggressive initial approach may be just as effective, a randomized trial suggests.

In the study that assigned patients with “rapidly deteriorating or severe” cardiogenic shock to one or the other approach, clinical outcomes were no better for those who received immediate ECMO than for those initially managed with inotropes and vasopressors, researchers said.

The conservative strategy, importantly, allowed for downstream ECMO in the event of hemodynamic deterioration, which occurred in a substantial 39% of cases, observed Petr Ostadal, MD, PhD, when presenting the results at the American Heart Association scientific sessions.

Dr. Ostadal of Na Homolce Hospital, Prague, is also first author on the published report of the study, called Extracorporeal Membrane Oxygenation in the Therapy of Cardiogenic Shock (ECMO-CS), which was published the same day in Circulation.

The trial makes a firm case for preferring the conservative initial approach over routine early ECMO in the kind of patients it entered, Larry A. Allen, MD, MHS, University of Coloradoat Denver, Aurora, told this news organization.

More than 60% of the trial’s 117 patients had shock secondary to an acute coronary syndrome; another 23% were in heart failure decompensation.

A preference for the conservative initial approach would be welcome, he said. The early aggressive ECMO approach is resource intensive and carries some important risks, such as stroke or coagulopathy, said Dr. Allen, who is not connected with ECMO-CS. Yet it is increasingly the go-to approach in such patients, based primarily on observational data.

Although early ECMO apparently didn’t benefit patients in this study in their specific stage of cardiogenic shock, Dr. Allen observed, it would presumably help some, but identifying them in practice presents challenges. “Defining where people are in the spectrum of early versus middle versus late cardiogenic shock is actually very tricky.”

It will therefore be important, he said, to identify ways to predict which conservatively managed patients do well with the strategy, and which are most at risk for hemodynamic deterioration and for whom ECMO should be readily available.

“I think part of what ECMO-CS tells us is that, if a patient is stable on intravenous inotropic and vasopressor support, you can defer ECMO while you’re thinking about the patient – about their larger context and the right medical decision-making for them.”

The trial randomly assigned 122 patients with rapidly deteriorating or severe cardiogenic shock to the immediate-ECMO or the conservative strategy at four centers in the Czech Republic. The 117 patients for whom informed consent could be obtained were included in the analysis, 58 and 59 patients, respectively. Their mean age was about 65 years and three-fourths were male.

The primary endpoint, the only endpoint for which the study was powered, consisted of death from any cause, resuscitated circulatory arrest, or use of a different form of mechanical circulatory support (MCS) by 30 days.

It occurred in 63.8% of patients assigned to immediate ECMO and 71.2% of those in the conservative strategy group, for a hazard ratio of 0.72 (95% confidence interval, 0.46-1.12; P = .21).

As individual endpoints, rates of death from any cause and resuscitated arrest did not significantly differ between the groups, but conservatively managed patients more often used another form of MCS. The HRs were 1.11 (95% CI, 0.66-1.87) for death from any cause, 0.79 (95% CI, 0.27-2.28) for resuscitated cardiac arrest, and 0.38 (95% CI, 0.18-0.79) for use of another MCS device.

The rates for serious adverse events – including bleeding, ischemia, stroke, pneumonia, or sepsis – were similar at 60.3% in the early-ECMO group and 61% in group with conservative initial management, Dr. Ostadal reported.

Other than the 23 patients in the conservative initial strategy group who went on to receive ECMO (1.9 days after randomization, on average), 1 went on to undergo implantation with a HeartMate (Abbott) ventricular assist device and 3 received an Impella pump (Abiomed).

Six patients in the early-ECMO group were already receiving intra-aortic balloon pump (IABP) support at randomization, two underwent temporary implantation with a Centrimag device (Abbott), and three went on to receive a HeartMate device, the published report notes.

ECMO is the optimal first choice for MCS in such patients with cardiogenic shock who need a circulatory support device, especially because it also oxygenates the blood, Dr. Ostadal told this news organization.

But ECMO doesn’t help with ventricular unloading. Indeed, it can sometimes reduce ventricular preload, especially if right-heart pressures are low. So MCS devices that unload the ventricle, typically an IABP, can complement ECMO.

Dr. Ostadal speculates, however, that there may be a better pairing option. “Impella plus ECMO, I think, is the combination which has a future,” he said, for patients in cardiogenic shock who need a short-term percutaneous hemodynamic support device. Impella “supports the whole circulation” and unloads the left ventricle.

“A balloon pump in combination with ECMO is still not a bad choice. It’s very cheap in comparison with Impella.” But in his opinion, Dr. Ostadal said, “The combination of Impella plus ECMO is more efficient from a hemodynamic point of view.”

As the published report notes, ongoing randomized trials looking at ECMO plus other MCS devices in cardiogenic shock include ECLS-SHOCK, with a projected enrollment of 420 patients, and EURO-SHOCK, aiming for a similar number of patients; both compare routine ECMO to conservative management.

In addition, ANCHOR, in which ECMO is combined with IABP, and DanShock, which looks at early use of Impella rather than ECMO, are enrolling patients with shock secondary to acute coronary syndromes.

Dr. Ostadal disclosed consulting for Getinge, Edwards, Medtronic, Biomedica, and Xenios/Fresenius, and receiving research support from Xenios/Fresenius. Dr. Allen disclosed modest or significant relationships with ACI Clinical, Novartis, UpToDate, Boston Scientific, and Cytokinetics.

“I think part of what ECMO-CS tells us is that, if a patient is stable on intravenous inotropic and vasopressor support, you can defer ECMO while you’re thinking about the patient – about their larger context and the right medical decision-making for them.”

The trial randomly assigned 122 patients with rapidly deteriorating or severe cardiogenic shock to the immediate-ECMO or the conservative strategy at four centers in the Czech Republic. The 117 patients for whom informed consent could be obtained were included in the analysis, 58 and 59 patients, respectively. Their mean age was about 65 years and three-fourths were male.

The primary endpoint, the only endpoint for which the study was powered, consisted of death from any cause, resuscitated circulatory arrest, or use of a different form of mechanical circulatory support (MCS) by 30 days.

It occurred in 63.8% of patients assigned to immediate ECMO and 71.2% of those in the conservative strategy group, for a hazard ratio of 0.72 (95% confidence interval, 0.46-1.12; P = .21).

As individual endpoints, rates of death from any cause and resuscitated arrest did not significantly differ between the groups, but conservatively managed patients more often used another form of MCS. The HRs were 1.11 (95% CI, 0.66-1.87) for death from any cause, 0.79 (95% CI, 0.27-2.28) for resuscitated cardiac arrest, and 0.38 (95% CI, 0.18-0.79) for use of another MCS device.

The rates for serious adverse events – including bleeding, ischemia, stroke, pneumonia, or sepsis – were similar at 60.3% in the early-ECMO group and 61% in group with conservative initial management, Dr. Ostadal reported.

Other than the 23 patients in the conservative initial strategy group who went on to receive ECMO (1.9 days after randomization, on average), 1 went on to undergo implantation with a HeartMate (Abbott) ventricular assist device and 3 received an Impella pump (Abiomed).

Six patients in the early-ECMO group were already receiving intra-aortic balloon pump (IABP) support at randomization, two underwent temporary implantation with a Centrimag device (Abbott), and three went on to receive a HeartMate device, the published report notes.

ECMO is the optimal first choice for MCS in such patients with cardiogenic shock who need a circulatory support device, especially because it also oxygenates the blood, Dr. Ostadal told this news organization.

But ECMO doesn’t help with ventricular unloading. Indeed, it can sometimes reduce ventricular preload, especially if right-heart pressures are low. So MCS devices that unload the ventricle, typically an IABP, can complement ECMO.

Dr. Ostadal speculates, however, that there may be a better pairing option. “Impella plus ECMO, I think, is the combination which has a future,” he said, for patients in cardiogenic shock who need a short-term percutaneous hemodynamic support device. Impella “supports the whole circulation” and unloads the left ventricle.

“A balloon pump in combination with ECMO is still not a bad choice. It’s very cheap in comparison with Impella.” But in his opinion, Dr. Ostadal said, “The combination of Impella plus ECMO is more efficient from a hemodynamic point of view.”

As the published report notes, ongoing randomized trials looking at ECMO plus other MCS devices in cardiogenic shock include ECLS-SHOCK, with a projected enrollment of 420 patients, and EURO-SHOCK, aiming for a similar number of patients; both compare routine ECMO to conservative management.

In addition, ANCHOR, in which ECMO is combined with IABP, and DanShock, which looks at early use of Impella rather than ECMO, are enrolling patients with shock secondary to acute coronary syndromes.

Dr. Ostadal disclosed consulting for Getinge, Edwards, Medtronic, Biomedica, and Xenios/Fresenius, and receiving research support from Xenios/Fresenius. Dr. Allen disclosed modest or significant relationships with ACI Clinical, Novartis, UpToDate, Boston Scientific, and Cytokinetics.

CHICAGO – Routine early, expeditious use of extracorporeal membrane oxygenation (ECMO) is a common strategy in patients with severe cardiogenic shock, but a less aggressive initial approach may be just as effective, a randomized trial suggests.

In the study that assigned patients with “rapidly deteriorating or severe” cardiogenic shock to one or the other approach, clinical outcomes were no better for those who received immediate ECMO than for those initially managed with inotropes and vasopressors, researchers said.

The conservative strategy, importantly, allowed for downstream ECMO in the event of hemodynamic deterioration, which occurred in a substantial 39% of cases, observed Petr Ostadal, MD, PhD, when presenting the results at the American Heart Association scientific sessions.

Dr. Ostadal of Na Homolce Hospital, Prague, is also first author on the published report of the study, called Extracorporeal Membrane Oxygenation in the Therapy of Cardiogenic Shock (ECMO-CS), which was published the same day in Circulation.

The trial makes a firm case for preferring the conservative initial approach over routine early ECMO in the kind of patients it entered, Larry A. Allen, MD, MHS, University of Coloradoat Denver, Aurora, told this news organization.

More than 60% of the trial’s 117 patients had shock secondary to an acute coronary syndrome; another 23% were in heart failure decompensation.

A preference for the conservative initial approach would be welcome, he said. The early aggressive ECMO approach is resource intensive and carries some important risks, such as stroke or coagulopathy, said Dr. Allen, who is not connected with ECMO-CS. Yet it is increasingly the go-to approach in such patients, based primarily on observational data.

Although early ECMO apparently didn’t benefit patients in this study in their specific stage of cardiogenic shock, Dr. Allen observed, it would presumably help some, but identifying them in practice presents challenges. “Defining where people are in the spectrum of early versus middle versus late cardiogenic shock is actually very tricky.”

It will therefore be important, he said, to identify ways to predict which conservatively managed patients do well with the strategy, and which are most at risk for hemodynamic deterioration and for whom ECMO should be readily available.

Vaping has become the dominant form of tobacco use by adolescents in the United States immediately after waking up, according to an analysis of a survey on teen tobacco use published in JAMA Network Open.

By 2019, Stanton Glantz, PhD, and associates found, “more e-cigarette users were using their first tobacco product within 5 minutes of waking than users of cigarettes and all other tobacco products combined.” Use upon waking is an indicator of addiction.

That number changed drastically from 2014 when less than 1% of sole-e-cigarette users were using e-cigarettes first thing in the morning to 10.3% by 2021. The numbers did not change for sole cigarette smokers or sole smokeless tobacco users, but did increase by half (odds ratio per year, 1.49) for sole cigar users.

In addition, among adolescents who currently use any tobacco product, the proportion whose first tobacco product was e-cigarettes increased from 27.2% in 2014 to 78.3% in 2019 and remained close to that at 77% in 2021.

Meanwhile, the number of young people using e-cigarettes peaked in 2019 and has been declining.

By 2019, the Centers for Disease Control and Prevention estimated that 5.3 million middle and high school students were using e-cigarettes. That number dropped to 3.6 million in 2020 and to 2.1 million in 2021 during the COVID-19 pandemic.
 

Researchers suspect more addictive nicotine

This increasing intensity of use may reflect the higher nicotine delivery and addiction liability of modern e-cigarettes that use protonated nicotine, which makes nicotine easier to inhale than older versions of e-cigarettes, which used freebase nicotine, Dr. Glantz and associates wrote.

The change in nicotine came in 2015 with the introduction of Juul products, they said, “which added benzoic acid to the nicotine e-liquid to lower the pH level and form protonated nicotine.”

The researchers advised: “Clinicians should question all their patients about nicotine and tobacco product use, including e-cigarettes and other new nicotine products.”

Raghu Appasani, MD, a psychiatrist who specializes in adolescent addiction and a clinical fellow at University of California, San Francisco, said in an interview that users often misunderstand the potential health effects of e-cigarettes and mistakenly think of them as a safe alternative to cigarettes.

All medical providers have a responsibility to ask patients about nicotine and tobacco products, Dr. Appasani said.
 

‘Be curious, not judgmental’

Dr. Appasani advised: “Be curious with your approach. This may uncover that maybe they use [e-cigarettes] to fit into a social scene or have stressors at home or in school. Most likely there is an underlying issue that has led to their use. Perhaps there is untreated anxiety and/or depression. Be curious, not judgmental.”

It is also important to ask about social and psychological factors that may be contributing to use and help the user think through how the use is affecting life in their home, school, and social settings, Dr. Appasani said.

He said he was not surprised by the findings as e-cigarettes allow easy access to smoking and it’s easier to hide the habit. The flavoring often get kids hooked originally.

The authors wrote: “These findings suggest that clinicians need to be ready to address youth addiction to these new highly addictive nicotine products during many clinical encounters, and stronger regulation is needed, including comprehensive bans on the sale of flavored tobacco products.”

Just more than half of the survey respondents (51.1%) were male and average age was 14. Researchers analyzed data from the National Youth Tobacco Survey, a nationally representative survey of middle and high school students.

They used the Youth Behavioral Risk Factor Surveillance System from 2015 to 2019 as a confirmatory analysis.

This study was supported in part by grants from the National Cancer Institute. Dr. Glantz received personal fees from the World Health Organization outside the submitted work. One coauthor reported serving as a paid expert witness against the tobacco industry outside the submitted work. No other disclosures were reported. Dr. Appasani declared no relevant financial relationships.

NASHVILLE, Tenn. – If a pulmonologist becomes involved early in the care of patients admitted to the hospital for an acute exacerbation of chronic obstructive pulmonary disease (AECOPD), the rate of readmission is reduced substantially relative to no pulmonologist involvement, according to a retrospective cohort review presented at the annual meeting of the American College of Chest Physicians (CHEST).

“When stratified by severity of COPD at the time of admission, the difference in the readmission rate was even greater,” reported Nakisa Hekmat-Joo, MD, a third-year resident at Staten Island University Hospital, New York.

Just as protocols have been developed for prompt initiation of antibiotics in patients with septicemia or prompt revascularization in patients with ST-segment elevated myocardial infarction (STEMI), Dr. Hekmat-Joo said the data from this study warrant a larger trial to evaluate whether an AECOPD admission protocol is warranted to improve outcomes and lower costs.

In this study, all AECOPD admissions were included from a recent 2-year period at two Staten Island hospitals. Of these, 198 patients received a pulmonologist consult within 24 hours. The remaining 92 patients were not evaluated by pulmonologists but were admitted and then managed by residents, internists, or others.

The primary outcome was length of stay (LOS). Although the slightly lower LOS in pulmonologist-treated group did not approach significance (4.16 vs. 4.21 days; P = .88), the readmission rate at 90 days, which was a secondary outcome, was reduced by almost half (30.1% vs. 57.6%; P < .0001).

At admission, there was no significant difference between those receiving a pulmonologist consult and those who did not. The average O₂ saturation was lower in the group seen by a pulmonologist (93% vs. 95.4%; P < .0001), but the most striking difference was the low relative readmission rate, which remained significant after controlling for severity and pulmonary function.

“When we stratified patients for baseline severity, the advantage of a pulmonologist consult was even greater for those with the most severe disease,” Dr. Hekmat-Joo said. Among those with the greatest severity, the 90-day readmission rate was nearly three times greater in the absence of a pulmonologist consult (72% vs. 28%).

Although the comparison of outcomes for those receiving a pulmonologist consult vs. those who did not was adjusted for COPD severity, the potential for pulmonologist consults to be ordered for those patients who looked the sickest would have likely worked against the study result.

“We speculate that pulmonologists were more likely than internists to treat beyond standard guidelines, particularly in the event of greater severity,” Dr. Hekmat-Joo explained. These steps might include earlier use of noninvasive positive pressure ventilation or earlier initiation of rehabilitation strategies.

There were several signals that a pulmonologist consult led to more rigorous care.

“The average time to follow-up after hospitalization was 23 days for the pulmonologist group and 66 days for the nonpulmonologist group,” said Dr. Hekmat-Joo, noting this difference was highly significant (P = .0052).

Based on these results, Dr. Hekmat-Joo and her co-investigators are now working on a protocol for COPD admissions that involves a pulmonologist consult within 24 hours of admission. She hopes to test this protocol in a prospective trial.

“COPD remains a major cause of death and consumes enormous health care resources. About 30% of the cost of COPD care is due to readmissions,” she said, noting that readmissions adversely impact quality of life.

Asked if there was sufficient staff at her institution to allow for a pulmonologist consult with every COPD admission, Dr. Hekmat-Joo acknowledged that this has to be demonstrated, but compelling evidence of a benefit might prompt a redistribution of resources.

“If we can show that readmissions are substantially reduced, adding staff to perform these consults would be a good investment,” said Dr. Hekmat-Joo, indicating that improved outcomes could also attract the attention of third-party payers and those tracking quality-of-care metrics.

There is a strong rationale for a randomized prospective trial to confirm the value of a pulmonologist consultation following admission for an acute exacerbation of COPD, according to Nicola A. Hanania, MD, director, Airways Clinical Research Center, Baylor College of Medicine, Houston.

The potential for benefit as seen in this retrospective study is a rational expectation and might be related to more appropriate therapy upon discharge as well as to earlier and more rigorous follow-up, according to Dr. Hanania. Although he cautioned that there is a meaningful risk of selection bias in a retrospective study, he thinks this study “is certainly probing an important issue.”

“Mortality from a hospitalized COPD exacerbation exceeds that of a myocardial infarction,” Dr. Hanania pointed out. Noting that all patients with an MI are evaluated by a cardiologist, he sees the logic of a pulmonologist consult – although he acknowledged that evidence is needed.

“I strongly believe that a prospective study is feasible and will answer the question in an unbiased manner if done properly,” he said in an interview. If a multicenter, well-controlled study was positive, it could change practice.

In the event of a study showing major clinical benefits, particularly a reduction in mortality, “I believe it is feasible to have a pulmonary consult to see every COPD exacerbation patient admitted to the hospital,” Dr. Hanania said.

Dr. Hekmat-Joo reports no relevant financial relationships. Dr. Hanania has financial relationships with AstraZeneca, Boehringer Ingelheim, GlaxoSmithKline, Mylan, Novartis, Regeneron, Sanofi, and Sunovion.

In this study, all AECOPD admissions were included from a recent 2-year period at two Staten Island hospitals. Of these, 198 patients received a pulmonologist consult within 24 hours. The remaining 92 patients were not evaluated by pulmonologists but were admitted and then managed by residents, internists, or others.

The primary outcome was length of stay (LOS). Although the slightly lower LOS in pulmonologist-treated group did not approach significance (4.16 vs. 4.21 days; P = .88), the readmission rate at 90 days, which was a secondary outcome, was reduced by almost half (30.1% vs. 57.6%; P < .0001).

At admission, there was no significant difference between those receiving a pulmonologist consult and those who did not. The average O₂ saturation was lower in the group seen by a pulmonologist (93% vs. 95.4%; P < .0001), but the most striking difference was the low relative readmission rate, which remained significant after controlling for severity and pulmonary function.

“When we stratified patients for baseline severity, the advantage of a pulmonologist consult was even greater for those with the most severe disease,” Dr. Hekmat-Joo said. Among those with the greatest severity, the 90-day readmission rate was nearly three times greater in the absence of a pulmonologist consult (72% vs. 28%).

Although the comparison of outcomes for those receiving a pulmonologist consult vs. those who did not was adjusted for COPD severity, the potential for pulmonologist consults to be ordered for those patients who looked the sickest would have likely worked against the study result.

“We speculate that pulmonologists were more likely than internists to treat beyond standard guidelines, particularly in the event of greater severity,” Dr. Hekmat-Joo explained. These steps might include earlier use of noninvasive positive pressure ventilation or earlier initiation of rehabilitation strategies.

There were several signals that a pulmonologist consult led to more rigorous care.

“The average time to follow-up after hospitalization was 23 days for the pulmonologist group and 66 days for the nonpulmonologist group,” said Dr. Hekmat-Joo, noting this difference was highly significant (P = .0052).

Based on these results, Dr. Hekmat-Joo and her co-investigators are now working on a protocol for COPD admissions that involves a pulmonologist consult within 24 hours of admission. She hopes to test this protocol in a prospective trial.

“COPD remains a major cause of death and consumes enormous health care resources. About 30% of the cost of COPD care is due to readmissions,” she said, noting that readmissions adversely impact quality of life.

Asked if there was sufficient staff at her institution to allow for a pulmonologist consult with every COPD admission, Dr. Hekmat-Joo acknowledged that this has to be demonstrated, but compelling evidence of a benefit might prompt a redistribution of resources.

“If we can show that readmissions are substantially reduced, adding staff to perform these consults would be a good investment,” said Dr. Hekmat-Joo, indicating that improved outcomes could also attract the attention of third-party payers and those tracking quality-of-care metrics.

There is a strong rationale for a randomized prospective trial to confirm the value of a pulmonologist consultation following admission for an acute exacerbation of COPD, according to Nicola A. Hanania, MD, director, Airways Clinical Research Center, Baylor College of Medicine, Houston.

The potential for benefit as seen in this retrospective study is a rational expectation and might be related to more appropriate therapy upon discharge as well as to earlier and more rigorous follow-up, according to Dr. Hanania. Although he cautioned that there is a meaningful risk of selection bias in a retrospective study, he thinks this study “is certainly probing an important issue.”

“Mortality from a hospitalized COPD exacerbation exceeds that of a myocardial infarction,” Dr. Hanania pointed out. Noting that all patients with an MI are evaluated by a cardiologist, he sees the logic of a pulmonologist consult – although he acknowledged that evidence is needed.

“I strongly believe that a prospective study is feasible and will answer the question in an unbiased manner if done properly,” he said in an interview. If a multicenter, well-controlled study was positive, it could change practice.

In the event of a study showing major clinical benefits, particularly a reduction in mortality, “I believe it is feasible to have a pulmonary consult to see every COPD exacerbation patient admitted to the hospital,” Dr. Hanania said.

Dr. Hekmat-Joo reports no relevant financial relationships. Dr. Hanania has financial relationships with AstraZeneca, Boehringer Ingelheim, GlaxoSmithKline, Mylan, Novartis, Regeneron, Sanofi, and Sunovion.

Just 3 weeks into the 2022-2023 flu season, the latest data from the Centers for Disease Control and Prevention’s Influenza Division suggest that the flu and respiratory syncytial virus are more than making up for the recent decline in COVID activity.

Outpatient visits for influenzalike illness (ILI), which includes influenza, SARS-CoV-2, and RSV, were higher after 3 weeks than for any of the previous five flu seasons: 3.3% of visits reported through the CDC’s Outpatient Influenza-like Illness Surveillance Network involved ILI as of Oct. 22. The highest comparable rate in the previous 5 years was the 1.9% recorded in late October of 2021, shortly after the definition of ILI was changed to also include illnesses other than influenza.

This season’s higher flu activity is in contrast to the previous two, which were unusually mild. The change, however, is not unexpected, as William Schaffner, MD, an infectious disease expert and professor of preventive medicine at Vanderbilt University, recently told CNN.

“Here we are in the middle of October – not the middle of November – we’re already seeing scattered influenza cases, even hospitalized influenza cases, around the country,” he said. “So we know that this virus is now spreading out in the community already. It’s gathering speed already. It looks to me to be about a month early.”

One indication of the mildness of the previous two flu seasons was the number of deaths, both pediatric and overall. Influenza-associated pediatric deaths had averaged about 110 per season over the previous eight seasons, compared with just 1 for 2020-2021 and 43 in 2021-2022. Overall flu deaths never reached 1% of all weekly deaths for either season, well below baseline levels for the flu, which range from 5.5% to 6.8%, CDC data show.
 

Other indicators of early severity

This season’s early rise in viral activity also can be seen in hospitalizations. The cumulative rate of flu-related admissions was 1.5 per 100,000 population as of Oct. 22, higher than the rate observed in the comparable week of previous seasons going back to 2010-2011, according to the CDC’s Influenza Hospitalization Surveillance Network.

A look at state reports of ILI outpatient visit rates shows that the District of Columbia and South Carolina are already in the very high range of the CDC’s severity scale, while 11 states are in the high range. Again going back to 2010-2011, no jurisdiction has ever been in the very high range this early in the season, based on data from the Outpatient Influenza-like Illness Surveillance Network.

Patients with the systemic sclerosis subtype of pulmonary arterial hypertension showed a distinctive bioactive metabolic profile associated with more severe disease than other subgroups, based on data from approximately 1,500 individuals.

The overall prognosis and therapeutic response for patients with pulmonary arterial hypertension associated with systemic sclerosis (SSc-PAH) tends to be worse than for patients with other types of PAH, such as idiopathic pulmonary arterial hypertension (IPAH), but the impact of different metabolite profiles among subtypes of disease has not been explored, wrote Mona Alotaibi, MD, of the University of California, San Diego, and colleagues.

“Recently, metabolic dysregulation has been proposed as a key mechanism by which IPAH and SSc-PAH differ and could control such disparities,” they noted. Clarifying the molecular mechanisms of SSc-PAH could inform management and treatment, they added.

In a study published in the journal Chest, the researchers sought to identify a bioactive lipid signature unique to SSc-PAH. They identified 400 patients with SSc-PAH and 1,082 with IPAH. An additional 100 patients with scleroderma but no PH and 44 patients with scleroderma who had PH were included for external validation. The mean ages of the patients with IPAH and SSc-PAH in the discovery and validation cohorts ranged from approximately 51 to 65 years; more than 75% of patients across the groups were women.

The researchers tested more than 700 bioactive lipid metabolites using liquid chromatography/mass spectrometry. They found five metabolites that distinguished SSc-PAH and IPAH that were significantly associated with markers of disease severity: 17-beta estradiol, novel Eic, nervonic acid, fatty acid esters of hydroxy fatty acids, and prostaglandin F2 alpha (PGF 2 alpha).

The biomarkers were increased in SSc-PAH patients compared to patients with SSC alone, which suggests that the biomarkers are related to PAH and not to scleroderma alone, the researchers noted.

In particular, nervonic acid was associated with worse functional capacity, in SSc-PAH patients, as were higher levels of 17-beta estradiol and prostaglandin F2 alpha. Also, 17-beta estradiol was associated with lower cardiac impairment (CI) and stroke volume index (SVI) in SSc-PAH patients, but higher SVI in IPAH patients. PGF 2 alpha was associated with lower CI and SVI and higher pulmonary vascular resistance in SSc-PAH and IPAH combined.

The study findings were limited by several factors including the inability to adjust for all potential confounders between IPAH and SSc-PAH, and the fact that a clear causal relationship could not be determined, the researchers noted. Inadequate statistical power to analyze SSc-PAH data was another limitation, and studies with detailed scleroderma phenotypes are needed to validate the results, they said.

However, the current study provides insight on the metabolic differences in SSc-PAH and the potential impact on disease pathology that may inform diagnosis, prognosis, and treatment strategies for SSc-PAH patients, they concluded.

The study was supported by the National Institutes of Health. Several individual investigators received support from organizations including the American Heart Association and the Chest Foundation, and from companies including Livanova, Equillium, Corvus, Bayer, and Actelion, but the authors had no relevant financial conflicts to disclose.

Smokers who quit before age 35 showed a "substantial" reduction in risk, compared with people who never smoked, according to a new national study.

Researchers also quantified the benefit of quitting for those older than 35. The added risk of death associated with smoking was reduced by 90% for those who quit before age 45 and 66% for those who quit at ages 45 to 64.

“The distal nature of the health consequences for young smokers is a challenge for professionals trying to motivate quitting in younger age groups. Without a proximal goal, it is tempting for smokers to abandon a quit attempt with cognitions such as ‘I don’t really need to do it just now,’ ” John P. Pierce, PhD, director for Population Sciences at UC-San Diego’s Moores Cancer Center, wrote in a commentary. 

Current smokers were twice as likely to die from any cause during the study, compared with the group researchers called “never smokers,” who were defined as smoking fewer than 100 lifetime cigarettes. 

Published in JAMA Network Open, the study involved 551,388 U.S. participants using information collected by the CDC from 1997 to 2018. Researchers collected data for specific causes of death of participants through the end of 2019.

The results echo past findings but also established whether demographic factors such as a smoker’s race and gender impact the benefits of quitting. (In many areas of health research, a person’s race or gender is associated with varying risks.)

The researchers found that the benefits of quitting smoking in reducing risk of death are comparable across demographic groups.

“Among former smokers in each racial and ethnic group, whether male or female, quitting was associated with reductions of approximately 80% of the excess mortality associated with continued smoking,” the authors stated. “These associations were generally consistent for deaths from cancer, cardiovascular disease, and lower respiratory disease.”

The findings are also important for guiding stop-smoking efforts because while smoking nationwide has decreased, the reduction has varied across demographic groups.

“Monitoring the association of smoking with mortality by race, ethnicity, and sex is critical to understanding how the U.S. tobacco epidemic continues to evolve over time and who is most affected by the changes,” the authors stated. “Despite continued decreases in U.S. smoking prevalence in recent decades, progress has not been equal across demographic groups. Recent progress in raising the quit ratio among U.S. ever-smokers overall has been modest, and the quit ratio has been consistently lower among Black and Hispanic ever-smokers than among non-Hispanic White ever-smokers.”

Offering shopping vouchers to pregnant women as an incentive to quit smoking showed promising results, a study found, despite most participants relapsing after giving birth.

Rewarding pregnant women with up to £400 to spend on Main Street, in addition to usual support, more than doubled the proportion who were still smoke-free late in their pregnancy, and could save the National Health Service money in the long term, according to the research, published in the BMJ, led by the University of Glasgow and the University of York, England.

Although the proportion of women in the United Kingdom who smoke during pregnancy has halved over the past 20 years, those who still do are more reluctant to engage with cessation services.

Interventions using financial incentives were pioneered in the United States, but there is a lack of evidence for how effective they might be in the United Kingdom.
 

Vouchers linked to passing saliva tests

The phase 3 Cessation in Pregnancy Incentives Trial was based on an earlier feasibility study in Glasgow and involved 941 pregnant women aged 16 or older, with a mean age of 27.9 years when they were recruited, from seven stop-smoking services in Scotland, Northern Ireland, and England between January 2018 and April 2020. Participants self-reported that they smoked at least one cigarette a week.

The cohort was randomised into two groups: a control group who received usual stop smoking support that included the offer of counselling by trained workers combined with free nicotine-replacement therapy, and an intervention group who were given the same interventional support plus targets to receive LoveToShop vouchers.

Although vouchers to the value of £400 were on offer, earning them depended on successfully reaching four milestones. They received a first £50 voucher for engaging with stop-smoking services and setting a quit date and further vouchers for being declared smoke-free by biochemical verification at specific time points in the pregnancy.

Factors including the mother’s age, years of smoking, income, use of nicotine-replacement therapy and e-cigarettes, timing of birth, and birth weight were taken into account.

The study found that 71% of the participants in the incentive group engaged with stop-smoking services and set a quit date, compared with 64% in the control group. By late pregnancy, 126 participants (27%) of the 471 in the intervention group were smoke-free, compared with 58 (12%) of the 470 in the control group.
 

Most women in the trial went back to smoking

However, abstinence rates measured 6 months after giving birth were low in both groups: 6% in the intervention group vs. 4% in the control group.

The researchers also reported no significant differences in birth weight between the two groups.

Overall, the birth weight of babies from 443 intervention participants and 450 controls showed no significant difference between groups (average 3.18 kg vs. 3.13 kg).

The researchers did find a clinically important but not significant 10% increase in birth weight in the subset of participants who adhered with their treatment allocation, but they said further analysis is needed to better understand the relevance of this finding.

Severity of preterm birth was similar between groups, and all serious adverse events, such as miscarriages and stillbirths, were considered unrelated to the intervention.

The researchers acknowledged some limitations to their investigation, including that only 23% of women screened by stop-smoking services were enrolled, and that almost all participants were White. Also, the onset of COVID-19 disrupted some of the trial processes.

However, they concluded that their trial “supports implementation advocated in NICE [National Institute for Health and Care Excellence] guidelines by showing an effective, cost-effective, and generalisable pragmatic bolt-on U.K. format for incentive payments” to reduce smoking rates in pregnancy.

The phase 3 Cessation in Pregnancy Incentives Trial was based on an earlier feasibility study in Glasgow and involved 941 pregnant women aged 16 or older, with a mean age of 27.9 years when they were recruited, from seven stop-smoking services in Scotland, Northern Ireland, and England between January 2018 and April 2020. Participants self-reported that they smoked at least one cigarette a week.

The cohort was randomised into two groups: a control group who received usual stop smoking support that included the offer of counselling by trained workers combined with free nicotine-replacement therapy, and an intervention group who were given the same interventional support plus targets to receive LoveToShop vouchers.

Although vouchers to the value of £400 were on offer, earning them depended on successfully reaching four milestones. They received a first £50 voucher for engaging with stop-smoking services and setting a quit date and further vouchers for being declared smoke-free by biochemical verification at specific time points in the pregnancy.

Factors including the mother’s age, years of smoking, income, use of nicotine-replacement therapy and e-cigarettes, timing of birth, and birth weight were taken into account.

The study found that 71% of the participants in the incentive group engaged with stop-smoking services and set a quit date, compared with 64% in the control group. By late pregnancy, 126 participants (27%) of the 471 in the intervention group were smoke-free, compared with 58 (12%) of the 470 in the control group.
 

Most women in the trial went back to smoking

However, abstinence rates measured 6 months after giving birth were low in both groups: 6% in the intervention group vs. 4% in the control group.

The researchers also reported no significant differences in birth weight between the two groups.

Overall, the birth weight of babies from 443 intervention participants and 450 controls showed no significant difference between groups (average 3.18 kg vs. 3.13 kg).

The researchers did find a clinically important but not significant 10% increase in birth weight in the subset of participants who adhered with their treatment allocation, but they said further analysis is needed to better understand the relevance of this finding.

Severity of preterm birth was similar between groups, and all serious adverse events, such as miscarriages and stillbirths, were considered unrelated to the intervention.

The researchers acknowledged some limitations to their investigation, including that only 23% of women screened by stop-smoking services were enrolled, and that almost all participants were White. Also, the onset of COVID-19 disrupted some of the trial processes.

However, they concluded that their trial “supports implementation advocated in NICE [National Institute for Health and Care Excellence] guidelines by showing an effective, cost-effective, and generalisable pragmatic bolt-on U.K. format for incentive payments” to reduce smoking rates in pregnancy.

Offering shopping vouchers to pregnant women as an incentive to quit smoking showed promising results, a study found, despite most participants relapsing after giving birth.

Rewarding pregnant women with up to £400 to spend on Main Street, in addition to usual support, more than doubled the proportion who were still smoke-free late in their pregnancy, and could save the National Health Service money in the long term, according to the research, published in the BMJ, led by the University of Glasgow and the University of York, England.

Although the proportion of women in the United Kingdom who smoke during pregnancy has halved over the past 20 years, those who still do are more reluctant to engage with cessation services.
