These viruses want mosquitoes with good taste

Taste can be a pretty subjective sense. Not everyone agrees on what tastes good and what tastes bad. Most people would agree that freshly baked cookies taste good, but what about lima beans? And what about mosquitoes? What tastes good to a mosquito?

The answer? Blood. Blood tastes good to a mosquito. That really wasn’t a very hard question, was it? You did know the answer, didn’t you? They don’t care about cookies, and they certainly don’t care about lima beans. It’s blood that they love.

That brings us back to subjectivity, because it is possible for blood to taste even better. The secret ingredient is dengue … and Zika.

A study just published in Cell demonstrates that mice infected with dengue and Zika viruses release a volatile compound called acetophenone. “We found that flavivirus [like dengue and Zika] can utilize the increased release of acetophenone to help itself achieve its lifecycles more effectively by making their hosts more attractive to mosquito vectors,” senior author Gong Cheng of Tsinghua University, Beijing, said in a written statement.

How do they do it? The viruses, he explained, promote the proliferation of acetophenone-producing skin bacteria. “As a result, some bacteria overreplicate and produce more acetophenone. Suddenly, these sick individuals smell as delicious to mosquitoes as a tray of freshly baked cookies to a group of five-year-old children,” the statement said.

And how do you stop a group of tiny, flying 5-year-olds? That’s right, with acne medication. Really? You knew that one but not the blood one before? The investigators fed isotretinoin to the infected mice, which led to reduced acetophenone release from skin bacteria and made the animals no more attractive to the mosquitoes than their uninfected counterparts.

The investigators are planning to take the next step – feeding isotretinoin to people with dengue and Zika – having gotten the official fictional taste-test approval of celebrity chef Gordon Ramsay, who said, “You’re going to feed this #$^% to sick people? ARE YOU &%*$@#& KIDDING ME?”

Okay, so maybe approval isn’t quite the right word.
 

Welcome to bladders of the rich and famous!

Don’t you hate it when you’re driving out to your multimillion-dollar second home in the Hamptons and traffic is so bad you absolutely have to find a place to “rest” along the way? But wouldn’t you know it, there just isn’t anywhere to stop! Geez, how do we live?

That’s where David Shusterman, MD, a urologist in New York City and a true American hero, comes in. He’s identified a market and positioned himself as the king of both bladder surgery and “bladder Botox” for the wealthy New Yorkers who regularly make long journeys from the city out to their second homes in the Hamptons. Traffic has increased dramatically on Long Island roads in recent years, and the journey can now taking upward of 4 hours. Some people just can’t make it that long without a bathroom break, and there are very few places to stop along the way.

Dr. Shusterman understands the plight of the Hamptons vacationer, as he told Insider.com: “I can’t tell you how many arguments I personally get into – I’ve lost three friends because I’m the driver and refuse to stop for them.” A tragedy worthy of Shakespeare himself.

During the summer season, Dr. Shusterman performs about 10 prostate artery embolizations a week, an hour-long procedure that shrinks the prostate, which is great for 50- to 60-year-old men with enlarged prostates that cause more frequent bathroom trips. He also performs Botox injections into the bladder once or twice a week for women, which reduces the need to urinate for roughly 6 months. The perfect amount of time to get them through the summer season.

These procedures are sometimes covered by insurance but can cost as much as $20,000 if paid out of pocket. That’s a lot of money to us, but if you’re the sort of person who has a second home in the Hamptons, $20,000 is chump change, especially if it means you won’t have to go 2 entire minutes out of your way to use a gas-station bathroom. Then again, having seen a more than a few gas-station bathrooms in our time, maybe they have a point.
 

Ditch the apples. Go for the avocados

We’ve all heard about “an apple a day,” but instead of apples you might want to go with avocados.

Avocados are generally thought to be a healthy fat. A study just published in the Journal of the American Heart Association proves that they actually don’t do anything for your waistline but will work wonders on your cholesterol level. The study involved 923 participants who were considered overweight/obese split into two groups: One was asked to consume an avocado a day, and the other continued their usual diets and were asked to consume fewer than two avocados a month.

At the end of the 6 months, the researchers found total cholesterol decreased by an additional 2.9 mg/dL and LDL cholesterol by 2.5 mg/dL in those who ate one avocado every day, compared with the usual-diet group. And even though avocados have a lot of calories, there was no clinical evidence that it impacted weight gain or any cardiometabolic risk factors, according to a statement from Penn State University.

Avocados, then, can be considered a guilt-free food. The findings from this study suggest it can give a substantial boost to your overall quality of diet, in turn lessening your risk of developing type 2 diabetes and some cancers, Kristina Peterson, PhD, assistant professor of nutritional sciences at Texas Tech University, said in the statement.

So get creative with your avocado recipes. You can only eat so much guacamole.
 

Your nose knows a good friend for you

You’ve probably noticed how dogs sniff other dogs and people before becoming friends. It would be pretty comical if people did the same thing, right? Just walked up to strangers and started sniffing them like dogs?

Well, apparently humans do go by smell when it comes to making friends, and they prefer people who smell like them. Maybe you’ve noticed that your friends look like you, share your values, and think the same way as you. You’re probably right, seeing as previous research has pointed to this.

For the current study, done to show how smell affects human behavior, researchers recruited people who befriended each other quickly, before knowing much about each other. They assumed that the relationships between these same-sex, nonromantic “click friends” relied more on physiological traits, including smell. After collecting samples from the click friends, researchers used an eNose to scan chemical signatures. In another experiment, human volunteers sniffed samples to determine if any were similar. Both experiments showed that click friends had more similar smells than pairs of random people.

Use of mepolizumab significantly reduced the need for maintenance oral corticosteroids in adults with severe asthma, based on data from more than 800 individuals.

Many patients with severe asthma require bursts of systemic corticosteroids (SCS) or maintenance oral corticosteroids (mOCS) for disease control, but these strategies are associated with side effects that can increase the disease burden, wrote Charles Pilette, MD, of Cliniques Universitaires Saint-Luc, Brussels, and colleagues.

Previous studies have shown that the humanized, monoclonal anti-interleukin (IL)–5 antibody mepolizumab, which is approved for the treatment of severe asthma, reduced use of SCS and has shown effectiveness in less homogeneous populations, but robust, real-world data on the occurrence and magnitude of these effects are lacking, the researchers said.

In a study known as REALITI-A, the researchers enrolled 822 adults with asthma diagnoses from 82 centers in Europe, Canada, and the United States who initiated mepolizumab at a subcutaneous dose of 100 mg. The study endpoints included daily use of oral corticosteroids at baseline and 1 year, percentage reduction in oral corticosteroid use from baseline, patients discontinuing oral corticosteroids; the primary outcome was the rate of clinically significant exacerbations (CSEs). CSEs were defined as the need for OCS for at least 3 days/parenteral administration, and/or an emergency department or hospital admission before and after treatment. The mean age of the participants was 54 years, 63% were women, and 60% were never-smokers. The mean asthma duration was 19.7 years.

A total of 319 patients (39%), used mOCS at baseline, and dose information was available for 298.

Real-world outcomes

At 1 year, the median mOCS dose in the study population was reduced by 75%, and 64% reduced their mOCS dose by at least 50% from baseline.

In addition, the proportion of patients who discontinued daily mOCS increased from 29% during week 25-28 to 43% during week 53-56.

Overall, 80% of patients remained on mepolizumab at 1 year. Lack of efficacy and patient decision were the top two reasons for discontinuation (6% and 4%, respectively).

The primary outcome of rate of CSE decreased by a clinically significant rate ratio of 0.29 (P < .001).

“The requirement for SCS bursts was also reduced, as observed by a decreased rate of CSEs,” the researchers wrote in their discussion. The results were consistent for patients receiving lower (less than 10 mg/day) or higher (10 mg/day or more) mOCS doses at baseline, they said. No unexpected safety signals were noted during the study period.

“Furthermore, mepolizumab was associated with significant decreases in the rate of exacerbations requiring hospitalizations, or those requiring hospitalization or an ER visit, improved symptom control, and lower work productivity and activity impairment,” they added.

The study findings were limited by several factors including the observational design, lack of mepolizumab comparator, and open-label data capture, the researchers noted. However, the results were consistent with similar studies, and support the use of mepolizumab as part of the standard of care for clinically effective disease control in severe asthma patients, they concluded.

The study was funded by GlaxoSmithKline. Lead author Dr. Pilette disclosed fees for advisory boards, speaker meetings, and 42 research grants from GSK, AstraZeneca, Chiesi, Novartis, Teva, and ALK-Abello.

Air pollution levels mediated the impact of temperature on oxygen saturation in adults with chronic obstructive pulmonary disease (COPD) based on data from 117 individuals.

COPD is attributed to environmental factors including air pollution, and air pollution has been linked to increased risk of hospitalization and mortality because of acute COPD exacerbation, wrote Huan Minh Tran, PhD, of Taipei (Taiwan) Medical University and colleagues. However, the effects of air pollution on climate-associated health outcomes in COPD have not been explored, they said.

In a study published in Science of The Total Environment the researchers identified 117 adult COPD patients at a single center in Taiwan. They measured lung function, 6-minute walking distance, oxygen desaturation, white blood cell count, and percent emphysema (defined as low attenuation area [LAA]) and linked them to 0- to 1-year, 0- to 3-year, and 0- to 5-year lags in exposures to relative humidity (RH), temperature, and air pollution. The mean age of the participants was 72.9 years; 93% were men.

Pollution was defined in terms of fine particulate matter (PM2.5).

Overall, an increase in RH by 1% was associated with increases in forced expiratory volume in 1 second (FEV₁), eosinophils, and lymphocytes.

A 1% increase in RH also was associated with a decrease in the total-lobe LAA.

As for temperature, an increase of 1° C was associated with decreased oxygen desaturation and with decreases in right-, left-, and upper-lobe LAA values.

When the researchers examined the impact of pollution, they found that a 1 mcg/m³ increase in PM2.5 was associated with a decrease in the FEV₁ as well as with an increase in oxygen desaturation. A 1 mcg/m³ increase in PM10 and PM2.5 was associated with increases in the total-, right-, left, and upper-lobe LAA; increases in lower-lobe LAA were associated with an increase in PM2.5 only.

“This is reasonable because PM2.5 can travel and deposit in distal parts of the lung, while PM10 is preferably deposited in the larger airways of the upper lung regions,” the researchers wrote in their discussion.

A one part per billion increase in nitrogen dioxide (NO₂) was associated with decreased FEV₁ and increased upper-lobe LAA.

“We observed that NO₂ fully mediated the association between RH and FEV₁, while PM2.5 fully mediated associations of temperature with oxygen saturation and emphysema severity in COPD patients,” the researchers added.

The study findings were limited by several factors including the relatively small and homogeneous male, Taiwanese population, which may limit generalizability, the researchers noted. Other limitations included the lack of control for factors such as body mass index, occupational exposure, comorbidities, medication use, and indoor air pollution, they said.

However, the results suggest that air pollution could have an effect on the established associations between climate and adverse health outcomes in COPD, and more research is needed. Climate change–related air pollution is an important public health issue, especially with regards to respiratory disease,” they concluded.

The study was supported by the Ministry of Science and Technology of Taiwan. The researchers had no financial conflicts to disclose.

Pollution was defined in terms of fine particulate matter (PM2.5).

Overall, an increase in RH by 1% was associated with increases in forced expiratory volume in 1 second (FEV₁), eosinophils, and lymphocytes.

A 1% increase in RH also was associated with a decrease in the total-lobe LAA.

As for temperature, an increase of 1° C was associated with decreased oxygen desaturation and with decreases in right-, left-, and upper-lobe LAA values.

When the researchers examined the impact of pollution, they found that a 1 mcg/m³ increase in PM2.5 was associated with a decrease in the FEV₁ as well as with an increase in oxygen desaturation. A 1 mcg/m³ increase in PM10 and PM2.5 was associated with increases in the total-, right-, left, and upper-lobe LAA; increases in lower-lobe LAA were associated with an increase in PM2.5 only.

“This is reasonable because PM2.5 can travel and deposit in distal parts of the lung, while PM10 is preferably deposited in the larger airways of the upper lung regions,” the researchers wrote in their discussion.

A one part per billion increase in nitrogen dioxide (NO₂) was associated with decreased FEV₁ and increased upper-lobe LAA.

“We observed that NO₂ fully mediated the association between RH and FEV₁, while PM2.5 fully mediated associations of temperature with oxygen saturation and emphysema severity in COPD patients,” the researchers added.

The study findings were limited by several factors including the relatively small and homogeneous male, Taiwanese population, which may limit generalizability, the researchers noted. Other limitations included the lack of control for factors such as body mass index, occupational exposure, comorbidities, medication use, and indoor air pollution, they said.

However, the results suggest that air pollution could have an effect on the established associations between climate and adverse health outcomes in COPD, and more research is needed. Climate change–related air pollution is an important public health issue, especially with regards to respiratory disease,” they concluded.

The study was supported by the Ministry of Science and Technology of Taiwan. The researchers had no financial conflicts to disclose.

Air pollution levels mediated the impact of temperature on oxygen saturation in adults with chronic obstructive pulmonary disease (COPD) based on data from 117 individuals.

COPD is attributed to environmental factors including air pollution, and air pollution has been linked to increased risk of hospitalization and mortality because of acute COPD exacerbation, wrote Huan Minh Tran, PhD, of Taipei (Taiwan) Medical University and colleagues. However, the effects of air pollution on climate-associated health outcomes in COPD have not been explored, they said.

In a study published in Science of The Total Environment the researchers identified 117 adult COPD patients at a single center in Taiwan. They measured lung function, 6-minute walking distance, oxygen desaturation, white blood cell count, and percent emphysema (defined as low attenuation area [LAA]) and linked them to 0- to 1-year, 0- to 3-year, and 0- to 5-year lags in exposures to relative humidity (RH), temperature, and air pollution.

About 80% of American adults have low to moderate cardiovascular (CV) health based on the American Heart Association checklist for optimal heart health, which now includes healthy sleep as an essential component for heart health.

With the addition of sleep, “Life’s Essential 8” replaces the AHA’s “Life’s Simple 7” checklist.

“The new metric of sleep duration reflects the latest research findings: Sleep impacts overall health, and people who have healthier sleep patterns manage health factors such as weight, blood pressure, or risk for type 2 diabetes more effectively,” AHA President Donald M. Lloyd-Jones, MD, said in a news release.

“In addition, advances in ways to measure sleep, such as with wearable devices, now offer people the ability to reliably and routinely monitor their sleep habits at home,” said Dr. Lloyd-Jones, chair of the department of preventive medicine at Northwestern University in Chicago.

The AHA Presidential Advisory – Life’s Essential 8: Updating and Enhancing the American Heart Association’s Construct on Cardiovascular Health – was published online in the journal Circulation.

A companion paper published simultaneously in Circulation reports the first study using Life’s Essential 8.

Overall, the results show that CV health of the U.S. population is “suboptimal, and we see important differences across age and sociodemographic groups,” Dr. Lloyd-Jones said.
 

Refining Life’s Simple 7

The AHA first defined the seven metrics for optimal CV health in 2010. After 12 years and more than 2,400 scientific papers on the topic, new discoveries in CV health and ways to measure it provided an opportunity to revisit each health component in more detail and provide updates as needed, the AHA explains.

“We felt it was the right time to conduct a comprehensive review of the latest research to refine the existing metrics and consider any new metrics that add value to assessing cardiovascular health for all people,” Dr. Lloyd-Jones said.

Four of the original metrics have been redefined for consistency with newer clinical guidelines or compatibility with new measurement tools, and the scoring system can now also be applied to anyone ages 2 and older. Here is a snapshot of Life’s Essential 8 metrics, including updates.

1. Diet (updated) 

The tool includes a new guide to assess diet quality for adults and children at the individual and population level. At the population level, dietary assessment is based on daily intake of elements in the Dietary Approaches to Stop Hypertension (DASH) eating pattern. For individuals, the Mediterranean Eating Pattern for Americans (MEPA) is used to assess and monitor cardiovascular health.

2. Physical activity (no changes)

Physical activity continues to be measured by the total number of minutes of moderate or vigorous physical activity per week, as defined by the U.S. Physical Activity Guidelines for Americans (2nd edition). The optimal level is 150 minutes (2.5 hours) of moderate physical activity or more per week or 75 minutes per week of vigorous-intensity physical activity for adults; 420 minutes (7 hours) or more per week for children ages 6 and older; and age-specific modifications for younger children.

3. Nicotine exposure (updated)

Use of inhaled nicotine-delivery systems, which includes e-cigarettes or vaping devices, has been added since the previous metric monitored only traditional, combustible cigarettes. This reflects use by adults and youth and their implications on long-term health. Second-hand smoke exposure for children and adults has also been added.

4. Sleep duration (new)

Sleep duration is associated with CV health. Measured by average hours of sleep per night, the ideal level is 7-9 hours daily for adults. Ideal daily sleep ranges for children are 10-16 hours per 24 hours for ages 5 and younger; 9-12 hours for ages 6-12 years; and 8-10 hours for ages 13-18 years.

5. Body mass index (no changes)

The AHA acknowledges that body mass index (BMI) is an imperfect metric. Yet, because it’s easily calculated and widely available, BMI continues as a “reasonable” gauge to assess weight categories that may lead to health problems. BMI of 18.5-24.9 is associated with the highest levels of CV health. The AHA notes that BMI ranges and the subsequent health risks associated with them may differ among people from diverse racial or ethnic backgrounds or ancestry. This aligns with the World Health Organization recommendations to adjust BMI ranges for people of Asian or Pacific Islander ancestry because recent evidence indicates their risk of conditions such as CVD or type 2 diabetes is higher at a lower BMI.

6. Blood lipids (updated)

The metric for blood lipids (cholesterol and triglycerides) is updated to use non-HDL cholesterol as the preferred number to monitor, rather than total cholesterol. This shift is made because non-HDL cholesterol can be measured without fasting beforehand (thereby increasing its availability at any time of day and implementation at more appointments) and reliably calculated among all people.

7. Blood glucose (updated)

This metric is expanded to include the option of hemoglobin A1c readings or blood glucose levels for people with or without type 1 or 2 diabetes or prediabetes.

8. Blood pressure (no changes)

Blood pressure criteria remain unchanged from 2017 guidance that established levels less than 120/80 mm Hg as optimal, and defined hypertension as 130-139 mm Hg systolic pressure or 80-89 mm Hg diastolic pressure.

‘Concerning’ new data

Results of the first study using Life’s Essential 8 show that the overall CV health of the U.S. population is “well below ideal,” with 80% of adults scoring at a low or moderate level, the researchers report.

Data for the analysis came from 2013-2018 U.S. National Health and Nutrition Examination surveys (NHANES) of more than 13,500 adults aged 20-79 years and nearly 9,900 children aged 2-19 years. Among the key findings:

• The average CV health score based on Life’s Essential 8 was 64.7 for adults and 65.5 for children – in the moderate range on the 0-100 scale.
• Only 0.45% of adults had a perfect score of 100; 20% had high CV health (score of 80 or higher), 63% moderate (score of 50-79), and 18% had low CV health (score of less than 50).
• Adult women had higher average CV health scores (67) compared with men (62.5).
• In general, adults scored lowest in the areas of diet, physical activity, and BMI.
• CV health scores were generally lower at older ages.
• Non-Hispanic Asian Americans had a higher average CV health score than other racial/ethnic groups. Non-Hispanic Whites had the second highest average CV health score, followed, in order, by Hispanic (other than Mexican), Mexican, and non-Hispanic Blacks.
• Children’s diet scores were low, at an average of 40.6.
• Adult sociodemographic groups varied notably in CV health scores for diet, nicotine exposure, blood glucose, and blood pressure.

“These data represent the first look at the cardiovascular health of the U.S. population using the AHA’s new Life’s Essential 8 scoring algorithm,” Dr. Lloyd-Jones said.

“Life’s Essential 8 is a major step forward in our ability to identify when cardiovascular health can be preserved and when it is suboptimal. It should energize efforts to improve cardiovascular health for all people and at every life stage,” Dr. Lloyd-Jones added.

“Analyses like this can help policymakers, communities, clinicians, and the public to understand the opportunities to intervene to improve and maintain optimal cardiovascular health across the life course,” he said.

This research had no commercial funding. The authors have no reported no relevant financial relationships.

When asthma patients are having frequent clinical deteriorations, clinicians need to evaluate them for the presence and severity of bronchiectasis, according to the authors of a retrospective study in the Journal of Allergy and Clinical Immunology: In Practice. While bronchiectasis is known to worsen the clinical and functional outcomes in patients with asthma, data regarding the long-term effects of bronchiectasis on the clinical course of asthma have been limited, stated corresponding author Jung-Kyu Lee, MD, division of pulmonary and critical care medicine, Seoul (Republic of Korea) Metropolitan Government – Seoul National University.

Moderate to severe acute clinical deterioration risks were increased among the 251 patients (mean age 66.6 years, 77.2% men) with bronchiectasis out of 667 asthma patients included in the study. All studied patients underwent chest computed tomography and pulmonary function tests from 2013 to 2019 at two tertiary hospitals in Seoul. The primary outcome, annual incidence of moderate to severe acute exacerbations requiring additional treatment (systemic steroids, antibiotics, or both), was significantly higher in patients with bronchiectasis after a mean follow-up period of 3.96 years. Compared with patients who did not exhibit bronchiectasis, the annual rates of severe exacerbations (0.15 ± 0.43 vs. 0.08 ± 0.27; P = .010), moderate to severe (0.47 ± 0.79 vs. 0.34 ± 0.63; P = .018), and acute exacerbations during the follow-up period (49.8% vs. 39.4%; P = .009) were all significantly higher. There was no difference in the proportion of frequent exacerbators between the two groups, however. Severe acute exacerbations leading to hospitalizations, also, were more frequent in the group with bronchiectasis.
 

Risk factors explored

Significant factors conferring greater risk of severe and moderate to severe acute exacerbations in multivariable analysis included low body mass index, low baseline forced expiratory volume in 1 second (FEV₁), high use of inhaled corticosteroids, high medication possession, and high neutrophil/lymphocyte ratios. The existence of bronchiectasis remained an independent risk factor for severe and moderate to severe acute exacerbations despite adjustment for all other factors. While bronchiectasis score showed no association with annual rate of acute exacerbation, progression of bronchiectasis confirmed on follow-up CT was associated with increased risks of severe and moderate to severe acute exacerbation.

Included patients had a diagnosis of asthma confirmed by variable expiratory airflow limitation with pulmonary function tests (that is, positive bronchodilator response, positive bronchial provocation test, or excessive variation in lung function between visits). Past histories of tuberculosis and nontuberculous mycobacterial lung disease, lower absolute and predicted values of both baseline FEV₁ and forced vital capacity were more common among patients with bronchiectasis.

Dividing the study population into a group that had at least one moderate to severe acute exacerbation during the follow-up period and a group that did not, the researchers identified characteristics shared by exacerbators: a greater proportion were women, they had lower forced vital capacity and lung-diffusing capacity for carbon monoxide, higher blood FVC and blood neutrophil/lymphocyte ratio, and more medication use (inhaled corticosteroids, long-acting antimuscarinic agent, leukotriene-receptor antagonist, and methylxanthine), compared with the nonexacerbators. More bronchiectasis, more severe bronchiectasis (higher bronchiectasis score), and more progression of bronchiectasis were common among the exacerbators.

Higher acute exacerbation risks accompanied bronchiectasis, at 1.47-fold for moderate, 1.72-fold for severe, and 1.50-fold for moderate to severe exacerbations. Higher risk for severe and moderate to severe exacerbations was conferred by bronchiectasis progression, also.

The researchers pointed to contradictory effects of inhaled corticosteroid use, noting both corticosteroids’ essential role in controlling airway inflammation and hyperresponsiveness, exacerbations, and lung-function decline in asthma patients and that longer or greater inhaled corticosteroid use is associated with both clinical deterioration in asthma and bronchiectasis, and exacerbation history. For bronchiectasis, however, inhaled corticosteroid use offers no benefit while increasing susceptibility to infection and its risks through partial immunosuppression.

“Considering these contradictory effects of inhaled corticosteroid use, further research is needed regarding its risks and benefits in asthma patients with bronchiectasis, including differences in the benefit of inhaled corticosteroid use according to patient phenotype,” Dr. Kim and his colleagues concluded.
 

The role of corticosteroids

“One of the more important points discussed in this observational cohort study is the role of inhaled corticosteroid use in bronchiectasis,” said Mary Jo Farmer, MD, PhD, director of pulmonary hypertension services, Baystate Health, and assistant professor of medicine, University of Massachusetts – Baystate, both in Springfield, in an interview with this news organization. She cited a review finding no significant benefit versus placebo in spirometry, exacerbation rate, or sputum volume in the Cochrane Database of Systematic Reviews and another suggesting that quality of life was improved with inhaled corticosteroid use in individuals with blood eosinophils greater than 3%, compared with those not using inhaled corticosteroids or having lower eosinophil counts in the European Respiratory Journal. She cited also higher percentages (48% versus 23%) of adrenal insufficiency in bronchiectasis patients among those taking inhaled corticosteroids versus those not taking them.

Dr. Farmer added, “According to the 2018 Cochrane review of inhaled corticosteroid treatment for non–cystic fibrosis bronchiectasis, results from most randomized, placebo-controlled trials have been disappointing in terms of effects on most endpoints such as pulmonary function and exacerbation frequency. As such, the European Respiratory Society guidelines for the management of adult bronchiectasis advise against prescribing inhaled corticosteroids to patients with bronchiectasis, unless otherwise indicated by either an asthma or chronic obstructive pulmonary disease diagnosis. Also, inhaled corticosteroid treatment in asthma and COPD is associated with common side effects such as oral candidiasis, dysphonia and, in some cases, systemic corticosteroid effects.

The study was independently supported.

When asthma patients are having frequent clinical deteriorations, clinicians need to evaluate them for the presence and severity of bronchiectasis, according to the authors of a retrospective study in the Journal of Allergy and Clinical Immunology: In Practice. While bronchiectasis is known to worsen the clinical and functional outcomes in patients with asthma, data regarding the long-term effects of bronchiectasis on the clinical course of asthma have been limited, stated corresponding author Jung-Kyu Lee, MD, division of pulmonary and critical care medicine, Seoul (Republic of Korea) Metropolitan Government – Seoul National University.

Moderate to severe acute clinical deterioration risks were increased among the 251 patients (mean age 66.6 years, 77.2% men) with bronchiectasis out of 667 asthma patients included in the study. All studied patients underwent chest computed tomography and pulmonary function tests from 2013 to 2019 at two tertiary hospitals in Seoul. The primary outcome, annual incidence of moderate to severe acute exacerbations requiring additional treatment (systemic steroids, antibiotics, or both), was significantly higher in patients with bronchiectasis after a mean follow-up period of 3.96 years. Compared with patients who did not exhibit bronchiectasis, the annual rates of severe exacerbations (0.15 ± 0.43 vs. 0.08 ± 0.27; P = .010), moderate to severe (0.47 ± 0.79 vs. 0.34 ± 0.63; P = .018), and acute exacerbations during the follow-up period (49.8% vs. 39.4%; P = .009) were all significantly higher. There was no difference in the proportion of frequent exacerbators between the two groups, however. Severe acute exacerbations leading to hospitalizations, also, were more frequent in the group with bronchiectasis.
 

Risk factors explored

Significant factors conferring greater risk of severe and moderate to severe acute exacerbations in multivariable analysis included low body mass index, low baseline forced expiratory volume in 1 second (FEV₁), high use of inhaled corticosteroids, high medication possession, and high neutrophil/lymphocyte ratios. The existence of bronchiectasis remained an independent risk factor for severe and moderate to severe acute exacerbations despite adjustment for all other factors. While bronchiectasis score showed no association with annual rate of acute exacerbation, progression of bronchiectasis confirmed on follow-up CT was associated with increased risks of severe and moderate to severe acute exacerbation.

Included patients had a diagnosis of asthma confirmed by variable expiratory airflow limitation with pulmonary function tests (that is, positive bronchodilator response, positive bronchial provocation test, or excessive variation in lung function between visits). Past histories of tuberculosis and nontuberculous mycobacterial lung disease, lower absolute and predicted values of both baseline FEV₁ and forced vital capacity were more common among patients with bronchiectasis.

Dividing the study population into a group that had at least one moderate to severe acute exacerbation during the follow-up period and a group that did not, the researchers identified characteristics shared by exacerbators: a greater proportion were women, they had lower forced vital capacity and lung-diffusing capacity for carbon monoxide, higher blood FVC and blood neutrophil/lymphocyte ratio, and more medication use (inhaled corticosteroids, long-acting antimuscarinic agent, leukotriene-receptor antagonist, and methylxanthine), compared with the nonexacerbators. More bronchiectasis, more severe bronchiectasis (higher bronchiectasis score), and more progression of bronchiectasis were common among the exacerbators.

Higher acute exacerbation risks accompanied bronchiectasis, at 1.47-fold for moderate, 1.72-fold for severe, and 1.50-fold for moderate to severe exacerbations. Higher risk for severe and moderate to severe exacerbations was conferred by bronchiectasis progression, also.

The researchers pointed to contradictory effects of inhaled corticosteroid use, noting both corticosteroids’ essential role in controlling airway inflammation and hyperresponsiveness, exacerbations, and lung-function decline in asthma patients and that longer or greater inhaled corticosteroid use is associated with both clinical deterioration in asthma and bronchiectasis, and exacerbation history. For bronchiectasis, however, inhaled corticosteroid use offers no benefit while increasing susceptibility to infection and its risks through partial immunosuppression.

“Considering these contradictory effects of inhaled corticosteroid use, further research is needed regarding its risks and benefits in asthma patients with bronchiectasis, including differences in the benefit of inhaled corticosteroid use according to patient phenotype,” Dr. Kim and his colleagues concluded.
 

The role of corticosteroids

“One of the more important points discussed in this observational cohort study is the role of inhaled corticosteroid use in bronchiectasis,” said Mary Jo Farmer, MD, PhD, director of pulmonary hypertension services, Baystate Health, and assistant professor of medicine, University of Massachusetts – Baystate, both in Springfield, in an interview with this news organization. She cited a review finding no significant benefit versus placebo in spirometry, exacerbation rate, or sputum volume in the Cochrane Database of Systematic Reviews and another suggesting that quality of life was improved with inhaled corticosteroid use in individuals with blood eosinophils greater than 3%, compared with those not using inhaled corticosteroids or having lower eosinophil counts in the European Respiratory Journal. She cited also higher percentages (48% versus 23%) of adrenal insufficiency in bronchiectasis patients among those taking inhaled corticosteroids versus those not taking them.

Dr. Farmer added, “According to the 2018 Cochrane review of inhaled corticosteroid treatment for non–cystic fibrosis bronchiectasis, results from most randomized, placebo-controlled trials have been disappointing in terms of effects on most endpoints such as pulmonary function and exacerbation frequency. As such, the European Respiratory Society guidelines for the management of adult bronchiectasis advise against prescribing inhaled corticosteroids to patients with bronchiectasis, unless otherwise indicated by either an asthma or chronic obstructive pulmonary disease diagnosis. Also, inhaled corticosteroid treatment in asthma and COPD is associated with common side effects such as oral candidiasis, dysphonia and, in some cases, systemic corticosteroid effects. The rate of adverse events from inhaled corticosteroid treatment of bronchiectasis, however, is largely unknown.Dr. Lee and Dr. Farmer reported no relevant financial relationships.

Consumers, employers, and just about everyone else interested in health care prices will soon get an unprecedented look at what insurers pay for care, perhaps helping answer a question that has long dogged those who buy insurance: Are we getting the best deal we can?

As of July 1, health insurers and self-insured employers must post on websites just about every price they’ve negotiated with providers for health care services, item by item. About the only thing excluded are the prices paid for prescription drugs, except those administered in hospitals or doctors’ offices.

The federally required data release could affect future prices or even how employers contract for health care. Many will see for the first time how well their insurers are doing, compared with others.

The new rules are far broader than those that went into effect in 2021 requiring hospitals to post their negotiated rates for the public to see. Now insurers must post the amounts paid for “every physician in network, every hospital, every surgery center, every nursing facility,” said Jeffrey Leibach, a partner at the consulting firm Guidehouse.

“When you start doing the math, you’re talking trillions of records,” he said. The fines the federal government could impose for noncompliance are also heftier than the penalties that hospitals face.

Federal officials learned from the hospital experience and gave insurers more direction on what was expected, said Mr. Leibach. Insurers or self-insured employers could be fined as much as $100 a day for each violation, for each affected enrollee if they fail to provide the data.

“Get your calculator out: All of a sudden you are in the millions pretty fast,” Mr. Leibach said.

Determined consumers, especially those with high-deductible health plans, may try to dig in right away and use the data to try comparing what they will have to pay at different hospitals, clinics, or doctor offices for specific services.

But each database’s enormous size may mean that most people “will find it very hard to use the data in a nuanced way,” said Katherine Baicker, dean of the University of Chicago Harris School of Public Policy.

At least at first.

Entrepreneurs are expected to quickly translate the information into more user-friendly formats so it can be incorporated into new or existing services that estimate costs for patients. And starting Jan. 1, the rules require insurers to provide online tools that will help people get up-front cost estimates for about 500 so-called “shoppable” services, meaning medical care they can schedule ahead of time.

Once those things happen, “you’ll at least have the options in front of you,” said Chris Severn, CEO of Turquoise Health, an online company that has posted price information made available under the rules for hospitals, although many hospitals have yet to comply.

With the addition of the insurers’ data, sites like his will be able to drill down further into cost variation from one place to another or among insurers.

“If you’re going to get an x-ray, you will be able to see that you can do it for $250 at this hospital, $75 at the imaging center down the road, or your specialist can do it in office for $25,” he said.

Everyone will know everyone else’s business: for example, how much insurers Aetna and Humana pay the same surgery center for a knee replacement.

The requirements stem from the Affordable Care Act and a 2019 executive order by then-President Donald Trump.

“These plans are supposed to be acting on behalf of employers in negotiating good rates, and the little insight we have on that shows it has not happened,” said Elizabeth Mitchell, president and CEO of the Purchaser Business Group on Health, an affiliation of employers who offer job-based health benefits to workers. “I do believe the dynamics are going to change.”

Other observers are more circumspect.

“Maybe at best this will reduce the wide variance of prices out there,” said Zack Cooper, director of health policy at the Yale University Institution for Social and Policy Studies, New Haven, Conn. “But it won’t be unleashing a consumer revolution.”

Still, the biggest value of the July data release may well be to shed light on how successful insurers have been at negotiating prices. It comes on the heels of research that has shown tremendous variation in what is paid for health care. A recent study by Rand, for example, shows that employers that offer job-based insurance plans paid, on average, 224% more than Medicare for the same services.

Tens of thousands of employers who buy insurance coverage for their workers will get this more-complete pricing picture – and may not like what they see.

“What we’re learning from the hospital data is that insurers are really bad at negotiating,” said Gerard Anderson, a professor in the department of health policy at the Johns Hopkins Bloomberg, Baltimore, citing research that found that negotiated rates for hospital care can be higher than what the facilities accept from patients who are not using insurance and are paying cash.

That could add to the frustration that Ms. Mitchell and others say employers have with the current health insurance system. More might try to contract with providers directly, only using insurance companies for claims processing.

Other employers may bring their insurers back to the bargaining table.

“For the first time, an employer will be able to go to an insurance company and say: ‘You have not negotiated a good-enough deal, and we know that because we can see the same provider has negotiated a better deal with another company,’ ” said James Gelfand, president of the ERISA Industry Committee, a trade group of self-insured employers.

If that happens, he added, “patients will be able to save money.”

That’s not necessarily a given, however.

Because this kind of public release of pricing data hasn’t been tried widely in health care before, how it will affect future spending remains uncertain. If insurers are pushed back to the bargaining table or providers see where they stand relative to their peers, prices could drop. However, some providers could raise their prices if they see they are charging less than their peers.

“Downward pressure may not be a given,” said Kelley Schultz, vice president of commercial policy for AHIP, the industry’s trade lobby.

Ms. Baicker said that, even after the data is out, rates will continue to be heavily influenced by local conditions, such as the size of an insurer or employer – providers often give bigger discounts, for example, to the insurers or self-insured employers that can send them the most patients. The number of hospitals in a region also matters – if an area has only one, for instance, that usually means the facility can demand higher rates.

Another unknown: Will insurers meet the deadline and provide usable data?

Ms. Schultz, at AHIP, said the industry is well on the way, partly because the original deadline was extended by 6 months. She expects insurers to do better than the hospital industry. “We saw a lot of hospitals that just decided not to post files or make them difficult to find,” she said.

So far, more than 300 noncompliant hospitals received warning letters from the government. But they could face fines of $300 a day fines for failing to comply, which is less than what insurers potentially face, although the federal government has recently upped the ante to up to $5,500 a day for the largest facilities.

Even after the pricing data is public, “I don’t think things will change overnight,” said Mr. Leibach. “Patients are still going to make care decisions based on their doctors and referrals, a lot of reasons other than price.”

The fourth vaccination against COVID-19 is the subject of intense discussion. Immunity against new Omicron variants (currently BA.4 and BA.5) is getting weaker and weaker. Is another vaccination with the available vaccines worth it?

For Leif Erik Sander, MD, director of infectious diseases and pneumology at Charité University Medicine, Berlin, the latest data send a clear message. “The COVID-19 vaccination is still effective against Omicron. After three doses of the vaccine, it continues to prevent severe diseases, respiratory failures, and death,” he reported at the 62nd Congress of the German Pneumology and Respiratory Medicine Society in Leipzig.

The most recent data from the United Kingdom show that the vaccine’s effectiveness against Omicron decreases after just a few months, which speaks in favor of a fourth vaccination. “Omicron is a development that we did not anticipate occurring so early on,” said Dr. Sander.

In terms of phylogenetics, Omicron is far removed from the previous variants of concern. More than 30 mutations to the spike protein (the antigen that is vaccinated against) foster the loss of immunity.
 

Boosters broaden immunity

“The booster makes all the difference here,” emphasized Dr. Sander. Experiments at Charité Berlin show that after double vaccination, the vaccination sera from healthy young people no longer neutralizes Omicron. But a third vaccination confers a very good neutralizing titer, even against Omicron.

“The third vaccination broadens the humoral immune response against the spike protein so that conserved epitopes that are unchanged, even in Omicron, are addressed, with the result that you have neutralization capacity again,” the infectious diseases specialist explained.
 

Continued protection

However, data from the United Kingdom on vaccine effectiveness show where the limit lies. Initially, after three doses, vaccine effectiveness against symptomatic disease after Omicron infection is very good. This effectiveness decreases significantly over the course of the next few months. “Lots of people experience an Omicron infection despite the booster,” said Mr. Sander.

Nonetheless, the high incidence of Omicron infections in the recent past has not overwhelmed the health care system. “This is because the vaccine’s effectiveness against severe diseases that require hospitalization and against respiratory failure is still good in the at-risk population over the age of 65, once they have had their three vaccinations,” said Dr. Sander. The data also show that there is good protection of over 90%, even against mortality.
 

Waning observed

It could be said that currently, vaccination even continues to work against Omicron, says Dr. Sander. It prevents severe disease, respiratory failure, and death. Nonetheless, after just 3 months, a slight waning of immune protection can be observed in all three endpoints.

Therefore, the question arises as to whether a fourth vaccination is worthwhile. In Israel, “Delta was successfully eradicated with the third vaccination,” and now they are trying this again for Omicron with a fourth vaccination, reported Dr. Sander.
 

Fourth vaccination protective

The first investigations show that protection against severe disease can be increased once more. “For the over-60s, protection is almost quadrupled through the fourth vaccination,” says Dr. Sander. “However, this is still plagued with a lot of uncertainty; it is still not known how stable it is.”

There is hope on the basis of results of an as yet non–peer-reviewed study from Sweden, which is currently available only as a preprint. That study shows that a fourth vaccination in a high-risk population of care-home residents and people older than 80 years can halve overall mortality. “If this can be confirmed and replicated, it must be recommended quite extensively for this high-risk group,” said Dr. Sander. The Standing Committee on Vaccination in Germany is currently recommending that high-risk groups be vaccinated against COVID-19 for the fourth time. To date, though, this has only been implemented halfheartedly.
 

Propensity for mutation

Omicron keeps developing. Following BA.1 and the more infectious subvariant BA.2, BA.4 and BA.5 are spreading in Germany. “To date, there is no evidence that vaccine protection against severe diseases has changed as a result of BA.2 emerging,” said Dr. Sander.

However, the loss of immunity against BA.4 and BA.5 is more strongly pronounced. “If you were infected with BA.1, you are not immune to BA.5,” says Dr. Sander. Lessened immunity from BA.4 and BA.5 is even more pronounced. “Anyone who was infected with BA.1 is not immune to BA.5,” says Dr. Sander. The two clades not only have spike protein mutations shared by BA.2 but also additional spike protein mutations. According to the expert, it could well be that these strains will prevail because they are best able to avoid the immunity of the population.
 

Adapted vaccines feasible?

“Vaccines adapted to BA.1 were developed very early on and were also part of clinical research,” said Dr. Sander. The initial data indicate that additional antibody responses are being mobilized that may neutralize the new variants.

It was deduced from trials on monkeys that the available vaccines were so good that only small improvements were to be expected, said Dr. Sander.
 

Moderna’s adapted vaccine

The U.S. pharmaceutical company Moderna recently submitted the first results regarding its bivalent Omicron vaccine mRNA-1273.214, which is adapted to Omicron BA.1. Data from BioNTech are expected soon.

Moderna tested a booster that contains both the spike mRNA from the original vaccine and a new mRNA adapted to the Omicron variant BA.1. The experimental vaccine mRNA-1273.214 exhibited an eightfold increase in geometric mean neutralization titer against Omicron in study participants who were seronegative at the start, compared with the already-approved vaccine.

In its latest notice, Moderna did not publish any data on how effective the updated vaccine is against the virus variants BA.4 or BA.5. Data on clinical endpoints, such as hospitalization or mortality, are also not available.
 

Conservative epitopes

Should it be assumed that the development of vaccines will always lag the emergence of new subvariants? In this respect, Dr. Sander appears optimistic. “The immunological mechanism is clear, that various B cells and antibodies will be formed that are directed against conservative epitopes that have various variants. This is good news, since we do not want to protect against BA.1 now, just for BA.8 to emerge when the vaccine goes to market. We want to protect ourselves as broadly as possible, and it seems like it may be possible to do so with this vaccine.”

Double vaccination?

Dr. Sander anticipates that a fourth vaccination against COVID-19 will occur with the next wave of the coronavirus in September or October. He remarked that coupling it with the influenza vaccination should be considered.

The coronavirus pandemic has led to shifts in other seasonal waves of pathogens. In the summer, pediatric departments were unexpectedly inundated with children suffering from RSV infections. And while the flu season over the past 2 years has been almost absent, the influenza wave may occur significantly earlier than usual this year.

“In Australia, the influenza wave arrived much earlier this year than usual, which may of course also be fruitful for us,” said Dr. Sander. “Perhaps we will also get influenza as early as in September or October. I would then plead for vaccine centers to be allowed to vaccinate against both influenza and COVID-19 at the same time. Maybe then we will also have a reasonable influenza vaccination rate,” he added.

Acute exacerbations (AEs) are both common in rheumatoid arthritis–associated interstitial lung disease (RA-ILD) and are a frequent cause of imminent mortality, a retrospective Japanese study suggests.

The same is also true for patients with idiopathic pulmonary fibrosis (IPF) for whom an AE is the most frequent cause of death as well, the same comparative study indicates.

“Several studies have reported that acute exacerbation, which occurs during the clinical course of idiopathic pulmonary fibrosis (IPF), also occurs in rheumatoid arthritis–associated interstitial lung disease (RA-ILD),” lead author Junji Otsuka, MD, PhD, of the National Hospital Organization Omuta National Hospital, Fukuoka, Japan, and colleagues observed.

“[We found that] AE was not uncommon in RA-ILD or IPF ... but the prognosis after AE of RA-ILD was significantly better than that of IPF [even though] the most frequent cause of death in RA-ILD and IPF was AE,” they stated.

The study was published online in Respiratory Medicine.

Patient features

The study involved 149 RA-ILD patients with a median age of 72 years at RA onset. The median time from ILD diagnosis to onset of AE was 48.5 months, while the median survival time after the onset of AE was 196 days (range 1-3,463 days), as the authors detailed. “All patients were treated with corticosteroids,” the authors noted, and almost all of them were treated with steroid pulse therapy.

Noninvasive positive pressure ventilation (NPPV) was used to maintain oxygenation in 18.5% of patients with severe respiratory failure, while invasive positive pressure ventilation (IPPV) was used in almost 26% of patients with the same degree of respiratory failure. Features of patients who developed an AE were then compared with those who did not.

Interestingly, no significant differences in clinical parameters were seen between those who developed an AE and those who did not. Nor were there any significant differences between the 2 groups in the length of time from the ILD diagnosis to the development of an AE. Some 18% of RA-ILD patients developed an AE, as did over 27% of patients with IPF, investigators report.

The median survival after RA-ILD patients developed an AE was 277 days, compared with only 60 days for those with IPF (P = .038). In a multivariable analysis, hypoalbuminemia at an odds ratio of .090 (95% confidence interval, 0.011-0.733; P = .012) as well as percent carbon monoxide diffusion capacity at an OR of .810 (95% CI, 0.814-0.964; P < .01) were both independent risk factors for the development of an AE, the investigators pointed out.

The best cut-off level for predicting the risk of an AE was 3.0 g/dL (95% CI, 0.011-0.733; P = .012) for serum albumin and 53% (95% CI, 0.814-0.964; P < .01) for carbon monoxide diffusion capacity. As Dr. Otsuka noted in an email to this news organization, low serum albumin likely correlates with a generally poor condition, while low carbon monoxide diffusion capacity is likely due to lung fibrosis.

“But if low albumin and low carbon monoxide diffusion capacity are due to the progression of ILD, both values may be difficult to improve,” he added.
 

Survivors versus nonsurvivors

Of those patients with RA-ILD who developed an AE, approximately half recovered. Among the IPF patients who developed an AE during the study period, approximately 39% recovered from the event, while 70% did not. Comparing RA-ILD patients who survived versus whose who did not, again, no significant demographic or clinical differences were seen between the 2 groups. On the other hand, the number of patients treated with immunosuppressants for their AE was significantly higher among patients who did not survive the AE, compared with those who did (P =.022), investigators note.

Similarly, the number of patients who required NPPV was also significantly higher among those who did not survive, compared with those who did. In fact, “none of the surviving patients used NPPV (P <0.01),” the authors stress. The number of patients who required IPPV was also significantly higher among nonsurvivors than among survivors (P =.017), and of the small number of patients who were treated with IPPV, all but one died without recovery.

As the authors suggested, these findings suggest that RA-ILD patients who recover from an AE with the help of corticosteroids alone have a relatively decent prognosis. In contrast, those who require immunosuppressive drugs in addition to steroids or mechanical ventilation for AE management can be expected to have a poor prognosis.

The same can also be said for IPF patients and even with the help of mechanical ventilation “with IPF patients, the survival rate is low anyway, so the indication for mechanical ventilation should be carefully judged,” Dr. Otsuka stressed.
 

Cause of death

The authors also compared the cause of death between patients with RA-ILD and those with IPF. “In RA-ILD patients, the most frequent cause of death was AE,” they report, at close to 35% of all patients with RA-ILD. This was also true for IPF patients among whom AE was the cause of death for over 44%. “These results indicate that, as in IPF, AE develops in the clinical course of RA-ILD with considerable frequency,” investigators note.

“During the clinical course of RA-ILD, as with IPD, it is necessary to pay attention to AE,” they stress. Dr. Otsuka added: “It may be difficult to change the prognosis of these patients.”

“However, knowing which patients are more likely to develop AE may help predict the prognosis, and it may be improved if antifibrotic agents are used for these patients,” he said. Elizabeth Volkmann, MD, director, UCLA scleroderma program, University of California, Los Angeles, felt that understanding the risk factors for AEs in this patient population may help physicians identify a subgroup of patients with RA-ILD who require closer monitoring and follow-up.

“These patients may also require more aggressive treatment for RA-ILD to prevent AEs,” she said in an email to this news organization. Given that the study was retrospective in nature, Dr. Volkmann cautioned that there were likely multiple confounding factors that could have affected survival in this patient population and not to take away from the study that survival was solely affected by immunosuppressant use, for example.

“It is possible that patients [treated with] immunosuppressants had other features of their disease that independently heightened their risk of mortality,” Dr. Volkmann said. Similarly, physicians should not assume that the high mortality rate seen in RA-ILD patients who were treated with mechanical ventilation had anything to do with mechanical ventilation itself, as patients requiring ventilation are likely to have worse outcomes, as she stressed.

As for hypoalbuminemia, Dr. Volkmann pointed out that hypoalbuminemia is often a sign of malnutrition in these patients. “Studies have demonstrated that malnutrition is an independent predictor of mortality in patients with ILD,” she emphasized.

“Optimizing patients’ nutritional status could potentially help lower the risk of AEs,” Dr. Volkmann suggested.

Limitations of the study include the fact that it was a single-center design study and included only a limited number of patients.

No specific funding source was noted. The authors have no conflicts of interest to declare.

“It is possible that patients [treated with] immunosuppressants had other features of their disease that independently heightened their risk of mortality,” Dr. Volkmann said. Similarly, physicians should not assume that the high mortality rate seen in RA-ILD patients who were treated with mechanical ventilation had anything to do with mechanical ventilation itself, as patients requiring ventilation are likely to have worse outcomes, as she stressed.

As for hypoalbuminemia, Dr. Volkmann pointed out that hypoalbuminemia is often a sign of malnutrition in these patients. “Studies have demonstrated that malnutrition is an independent predictor of mortality in patients with ILD,” she emphasized.

“Optimizing patients’ nutritional status could potentially help lower the risk of AEs,” Dr. Volkmann suggested.

Limitations of the study include the fact that it was a single-center design study and included only a limited number of patients.

Acute exacerbations (AEs) are both common in rheumatoid arthritis–associated interstitial lung disease (RA-ILD) and are a frequent cause of imminent mortality, a retrospective Japanese study suggests.

The same is also true for patients with idiopathic pulmonary fibrosis (IPF) for whom an AE is the most frequent cause of death as well, the same comparative study indicates.

“Several studies have reported that acute exacerbation, which occurs during the clinical course of idiopathic pulmonary fibrosis (IPF), also occurs in rheumatoid arthritis–associated interstitial lung disease (RA-ILD),” lead author Junji Otsuka, MD, PhD, of the National Hospital Organization Omuta National Hospital, Fukuoka, Japan, and colleagues observed.

“[We found that] AE was not uncommon in RA-ILD or IPF ... but the prognosis after AE of RA-ILD was significantly better than that of IPF [even though] the most frequent cause of death in RA-ILD and IPF was AE,” they stated.

The study was published online in Respiratory Medicine.

Patient features

The study involved 149 RA-ILD patients with a median age of 72 years at RA onset. The median time from ILD diagnosis to onset of AE was 48.5 months, while the median survival time after the onset of AE was 196 days (range 1-3,463 days), as the authors detailed. “All patients were treated with corticosteroids,” the authors noted, and almost all of them were treated with steroid pulse therapy.

Noninvasive positive pressure ventilation (NPPV) was used to maintain oxygenation in 18.5% of patients with severe respiratory failure, while invasive positive pressure ventilation (IPPV) was used in almost 26% of patients with the same degree of respiratory failure. Features of patients who developed an AE were then compared with those who did not.

Interestingly, no significant differences in clinical parameters were seen between those who developed an AE and those who did not. Nor were there any significant differences between the 2 groups in the length of time from the ILD diagnosis to the development of an AE. Some 18% of RA-ILD patients developed an AE, as did over 27% of patients with IPF, investigators report.

The median survival after RA-ILD patients developed an AE was 277 days, compared with only 60 days for those with IPF (P = .038). In a multivariable analysis, hypoalbuminemia at an odds ratio of .090 (95% confidence interval, 0.011-0.733; P = .012) as well as percent carbon monoxide diffusion capacity at an OR of .810 (95% CI, 0.814-0.964; P < .01) were both independent risk factors for the development of an AE, the investigators pointed out.

The best cut-off level for predicting the risk of an AE was 3.0 g/dL (95% CI, 0.011-0.733; P = .012) for serum albumin and 53% (95% CI, 0.814-0.964; P < .01) for carbon monoxide diffusion capacity. As Dr. Otsuka noted in an email to this news organization, low serum albumin likely correlates with a generally poor condition, while low carbon monoxide diffusion capacity is likely due to lung fibrosis.

“But if low albumin and low carbon monoxide diffusion capacity are due to the progression of ILD, both values may be difficult to improve,” he added.
 

Survivors versus nonsurvivors

Of those patients with RA-ILD who developed an AE, approximately half recovered. Among the IPF patients who developed an AE during the study period, approximately 39% recovered from the event, while 70% did not. Comparing RA-ILD patients who survived versus whose who did not, again, no significant demographic or clinical differences were seen between the 2 groups. On the other hand, the number of patients treated with immunosuppressants for their AE was significantly higher among patients who did not survive the AE, compared with those who did (P =.022), investigators note.

Similarly, the number of patients who required NPPV was also significantly higher among those who did not survive, compared with those who did. In fact, “none of the surviving patients used NPPV (P <0.01),” the authors stress. The number of patients who required IPPV was also significantly higher among nonsurvivors than among survivors (P =.017), and of the small number of patients who were treated with IPPV, all but one died without recovery.

As the authors suggested, these findings suggest that RA-ILD patients who recover from an AE with the help of corticosteroids alone have a relatively decent prognosis. In contrast, those who require immunosuppressive drugs in addition to steroids or mechanical ventilation for AE management can be expected to have a poor prognosis.

The same can also be said for IPF patients and even with the help of mechanical ventilation “with IPF patients, the survival rate is low anyway, so the indication for mechanical ventilation should be carefully judged,” Dr. Otsuka stressed.
 

Cause of death

The authors also compared the cause of death between patients with RA-ILD and those with IPF. “In RA-ILD patients, the most frequent cause of death was AE,” they report, at close to 35% of all patients with RA-ILD. This was also true for IPF patients among whom AE was the cause of death for over 44%. “These results indicate that, as in IPF, AE develops in the clinical course of RA-ILD with considerable frequency,” investigators note.

“During the clinical course of RA-ILD, as with IPD, it is necessary to pay attention to AE,” they stress. Dr. Otsuka added: “It may be difficult to change the prognosis of these patients.”

“However, knowing which patients are more likely to develop AE may help predict the prognosis, and it may be improved if antifibrotic agents are used for these patients,” he said. Elizabeth Volkmann, MD, director, UCLA scleroderma program, University of California, Los Angeles, felt that understanding the risk factors for AEs in this patient population may help physicians identify a subgroup of patients with RA-ILD who require closer monitoring and follow-up.

“These patients may also require more aggressive treatment for RA-ILD to prevent AEs,” she said in an email to this news organization. Given that the study was retrospective in nature, Dr. Volkmann cautioned that there were likely multiple confounding factors that could have affected survival in this patient population and not to take away from the study that survival was solely affected by immunosuppressant use, for example.

Ask the sibling of any celebrity and they’ll tell you they don’t get anywhere near the same attention. The same is true for coronaviruses – the one that causes COVID-19 has been in the spotlight for more than 2 years now, while the others at the moment circulate in relative obscurity.

With the knowledge that any of the other coronaviruses could pose a serious future threat, Pfizer and its partner BioNTech announced plans on June 29 to develop a vaccine that will work against SARS-CoV-2 (the virus that causes COVID-19) and the entire class, or family, of related coronaviruses.

Trials in people of this “pan-coronavirus” vaccine are scheduled to start this fall, Reuters reported. The aim of this universal vaccine is to lessen the threat from new variants before they emerge – to provide “durable variant protection.”

“I applaud the sentiment that is long overdue,” said Eric Topol, MD, when asked to comment. “It is crucial that we get ahead of the virus, and the best way is to develop pan-betacoronavirus vaccines that are variant-proof.”

“We had potential to get them into clinical trials many months ago, but this is the first sign it may happen,” said Dr. Topol, executive vice president of Scripps Research and editor-in-chief for Medscape, WebMD’s sister site for health care professionals.

SARS-CoV-2 is not the first troublemaker in the coronavirus family. SARS, a coronavirus that causes acute respiratory syndrome, emerged in late 2002. A decade later, officials sounded the alarm about the coronavirus behind Middle East respiratory syndrome (MERS).

The coronavirus family is large, but only seven coronavirus types can infect humans, the CDC reports. Most cause mild to moderate upper respiratory tract infections, although some people can get pneumonia or bronchiolitis.

Unless you’re a virologist, immunologist, or public health official, you may be unaware that coronaviruses are one of the causes of the common cold, for example.

Cannabis users had a 22% increased risk of an emergency department (ED) visit or hospitalization compared to nonusers, as determined from data from more than 30,000 individuals.

Although cannabis contains compounds similar to tobacco, “data published on the association between cannabis smoking and airways health have been contradictory,” and whether smoking cannabis increases a user’s risk of developing acute respiratory illness remains unclear, wrote Nicholas T. Vozoris, MD, of the University of Toronto, and colleagues.

In a study published in BMJ Open Respiratory Research, the investigators reviewed national health records data from 35,114 individuals aged 12-65 years for the period January 2009 to December 2015. Of these persons, 4,807 of the 6,425 who reported cannabis use in the past year were matched with 10,395 never-users who served as controls. The mean age of the study population at the index date was 35 years, and 42% were women; demographics were similar between users and control persons.

Overall, the odds of respiratory-related emergency department visits or hospitalizations were not significantly different between the cannabis users and the control persons (3.6% vs. 3.9%; odds ratio, 0.91). However, cannabis users had significantly greater odds of all-cause ED visits or hospitalizations (30.0% vs. 26.0%; OR, 1.22). All-cause mortality was 0.2% for both groups.

Respiratory problems were the second-highest reason for all-cause visits, the researchers noted. The lack of a difference in respiratory-related visits between cannabis users and nonusers conflicts somewhat with previous studies on this topic, which were limited, the researchers noted in their discussion.

The negative results also might stem from factors for which the researchers could not adjust, including insufficient cannabis smoke exposure among users in the study population, noninhalational cannabis use, which is less likely to have a respiratory effect, and possible secondhand exposure among control persons.

“It is also possible that our analysis might have been insufficiently powered to detect a significant signal with respect to the primary outcome,” they noted.

However, after the researchers controlled for multiple variables, the risk of an equally important morbidity outcome, all-cause ED visits or hospitalizations, was significantly greater among cannabis users than among control individuals, and respiratory reasons were the second most common cause for ED visits and hospitalizations in the all-cause outcome, they emphasized.

The study findings were limited by several factors, including the retrospective and observational design and the inability to control for all confounding variables, the researchers noted. Other limitations include the use of self-reports and potential for bias, the inability to perform dose-response analysis, and the high number of infrequent cannabis users in the study population.

However, the results suggest that cannabis use is associated with an increased risk of serious health events and should be discouraged, although more research is needed to confirm the current study findings, they concluded.
 

Consider range of causes for cannabis emergency visits

“With growing numbers of states legalizing recreational use of cannabis, it’s important to understand whether cannabis use is associated with increased emergency department visits,” Robert D. Glatter, MD, an emergency medicine physician at Lenox Hill Hospital, New York, told this news organization.

Previous studies have shown an association between increased ED visits and cannabis use in states, especially with edibles, where cannabis is legal, and “the current study reinforces the elevated risk of ED visits along with hospitalizations,” he said.

“While the researchers found no increased risk of respiratory-related complaints among users compared to the general population, there was an associated increase in ED visits and hospitalizations, which is important to understand,” said Dr. Glatter, who was not involved in the study.

“While this observational study found that the incidence of respiratory complaints was not significantly different among frequent users of cannabis, the increased odds that cannabis users would require evaluation in the emergency room or even hospitalization was still apparent even after the investigators controlled for such factors as use of alcohol, tobacco, illicit drug use, or other mental health–related disorders,” Dr. Glatter noted.

“That said, it’s a bit surprising that with the continued popularity of vaping, especially among teens, there was still not any appreciable or significant increase in respiratory complaints observed. Beyond this finding, I was not surprised by the overall conclusions of the current study, as we continue to see an elevated number of patients presenting to the ED with adverse events related to cannabis use.”

Dr. Glatter noted that “the majority of patients we see in the ED are associated with use of edibles, since it takes longer for the person to feel the effects, leading the user to consume more of the product up front, with delayed effects lasting up to 12 hours. This is what gets people into trouble and leads to toxicity of cannabis, or ‘overdoses,’ “ he explained.

When consuming edible cannabis products, “[p]eople need to begin at low dosages and not take additional gummies up front, since it can take up to 2 or even 3 hours in some cases to feel the initial effects. With the drug’s effects lasting up to 12 hours, it’s especially important to avoid operating any motor vehicles, bicycles, or scooters, since reaction time is impaired, as well as overall judgment, balance, and fine motor skills,” Dr. Glatter said.

Cannabis can land users in the ED for a range of reasons, said Dr. Glatter. “According to the study, 15% of the emergency room visits and hospitalizations were due to acute trauma, 14% due to respiratory issues, and 13% to gastrointestinal illnesses. These effects were seen in first-time users but not those with chronic use, according to the study inclusion criteria.”

Cannabis use could result in physical injuries through “impaired judgment, coordination, combined with an altered state of consciousness or generalized drowsiness, that could contribute to an increase in motor vehicle collisions, along with an increased risk for falls leading to lacerations, fractures, contusions, or bruising,” said Dr. Glatter. “Cannabis may also lead to an altered sense of perception related to interactions with others, resulting in feelings of anxiety or restlessness culminating in physical altercations and other injuries.”

The current study indicates the need for understanding the potential physical and psychological effects of cannabis use, he said.

“Additional research is needed to better understand the relative percentage cases related to edibles vs. inhalation presenting to the ED,” he noted. “There is no question that edibles continue to present significant dangers for those who don’t read labels or remain poorly informed regarding their dosing as a result of delayed onset and longer duration,” he said. To help reduce risk of toxicity, the concept of a “high lasting 12-15 hours, as with edibles, as opposed to 3-4 hours from inhalation must be clearly stated on packaging and better communicated with users, as the toxicity with edibles is more often from lack of prior knowledge about onset of effects related to dosing.”

In addition, the “potential for psychosis to develop with more chronic cannabis use, along with cannabinoid hyperemesis syndrome should be on every clinician’s radar,” Dr. Glatter emphasized.

“The bottom line is that as more states legalize the use of cannabis, it’s vital to also implement comprehensive public education efforts to provide users with the reported risks associated with not only inhalation (vaping or flower) but also edibles, which account for an increasingly greater percentage of ED visits and associated adverse effects,” he said.

The study was supported by the Lung Association–Ontario, as well as by grants from the Ontario Ministry of Health and the Ministry of Long-Term Care. The researchers and Dr. Glatter have disclosed no relevant financial relationships.

Cannabis use could result in physical injuries through “impaired judgment, coordination, combined with an altered state of consciousness or generalized drowsiness, that could contribute to an increase in motor vehicle collisions, along with an increased risk for falls leading to lacerations, fractures, contusions, or bruising,” said Dr. Glatter. “Cannabis may also lead to an altered sense of perception related to interactions with others, resulting in feelings of anxiety or restlessness culminating in physical altercations and other injuries.”

The current study indicates the need for understanding the potential physical and psychological effects of cannabis use, he said.

“Additional research is needed to better understand the relative percentage cases related to edibles vs. inhalation presenting to the ED,” he noted. “There is no question that edibles continue to present significant dangers for those who don’t read labels or remain poorly informed regarding their dosing as a result of delayed onset and longer duration,” he said. To help reduce risk of toxicity, the concept of a “high lasting 12-15 hours, as with edibles, as opposed to 3-4 hours from inhalation must be clearly stated on packaging and better communicated with users, as the toxicity with edibles is more often from lack of prior knowledge about onset of effects related to dosing.”

In addition, the “potential for psychosis to develop with more chronic cannabis use, along with cannabinoid hyperemesis syndrome should be on every clinician’s radar,” Dr. Glatter emphasized.

“The bottom line is that as more states legalize the use of cannabis, it’s vital to also implement comprehensive public education efforts to provide users with the reported risks associated with not only inhalation (vaping or flower) but also edibles, which account for an increasingly greater percentage of ED visits and associated adverse effects,” he said.

The study was supported by the Lung Association–Ontario, as well as by grants from the Ontario Ministry of Health and the Ministry of Long-Term Care. The researchers and Dr. Glatter have disclosed no relevant financial relationships.
