CHEST releases guideline on biologic management in severe asthma

2026-01-13
(Press-News.org) Glenview, Illinois –The American College of Chest Physicians® (CHEST) recently released a new clinical guideline on biologic management in severe asthma. Published in the journal CHEST®, the guideline contains seven evidence-based recommendations to provide a framework for pulmonologists, allergists, and immunologists to implement in their own practice. 

Severe asthma affects 5% to 10% of patients with asthma, which is defined as patients who require high-dose inhaled corticosteroids plus a second controller. Biologic agents have become a standard of care in those unresponsive to standard treatments, yet the choice of biologic agent remains highly complex. This CHEST guideline examines existing biologics and provides evidence-based recommendations for which biologics to consider for different patient populations. 

“While there are studies available to help guide the clinician for initial biologic selection, to date, there is no published guideline to assist in biologic selection when a patient has tried and failed one or more biologics,” said Amber J. Oberle, MD, lead author on the guideline. “In addition to following this guideline, decisions as to how to individualize biological therapy should occur under a shared decision-making process that carefully considers underlying asthma comorbidities, T2 biomarkers, injection frequency, mode of administration, and access to resources.”

According to panel consensus, patients lacking a good clinical response after four to six months should switch to an alternative biologic. Characteristics such as baseline oral corticosteroid use, frequency of exacerbation, asthma endotype with available biomarker data, baseline lung function, and comorbid conditions can impact the biologic choice.

Of the seven recommendations, highlights include: 

In adult patients with moderate to severe allergic asthma and a history of ≥ one exacerbation per year requiring oral corticosteroids, the panel suggests either omalizumab or dupilumab; however, for patients with more frequent or severe exacerbations requiring hospitalization, the panel recommends dupilumab over omalizumab.  In adult patients with severe asthma who are steroid dependent, the panel suggests anti-IL-5 therapy or dupilumab over tezepelumab. In adult patients with severe asthma who have not demonstrated a clinical response to an initial biologic agent, the switching of agents will be largely influenced by corticosteroid dependency and/or T2 biomarkers.   Specifically for patients who have failed to demonstrate a clinical response to anti-IL-5 therapy, obtaining posttreatment fractional exhaled nitric oxide is recommended to help guide decision-making.  The entire list of recommendations included in the new guideline can be accessed through the CHEST journal website in the article titled, “Biologic Management in Severe Asthma for Adults: An American College of Chest Physicians Clinical Practice Guideline.”

Scientists create a system for tracking underwater blackouts

2026-01-13
(Santa Barbara, Calif.) — Clouds, smoke and fog may darken the skies, but sediment, algae blooms and organic matter can turn day into night on the seafloor. That’s why an international team of scientists have created the first framework to identify and compare these marine blackouts. The study, published in Communications Earth & Environment, introduces the concept of a marine darkwave: a short-term but intense episode of underwater darkness that can severely impact kelp forests, seagrass beds and other light-dependent ...

Fruit fly pigmentation guides discovery of genes that control brain dopamine and sleep

2026-01-13
Dopamine in the brain influences movement, learning, motivation and sleep. In humans, problems with dopamine are linked to conditions like Parkinson’s disease, depression and sleep disorders. While scientists know a great deal about how dopamine works in the brain, they know less about how the body controls dopamine levels. Understanding this could help treat diseases where dopamine is disrupted. In a new study published in iScience, researchers at Baylor College of Medicine and the Jan and Dan Duncan Neurological Institute at Texas Children’s Hospital (Duncan NRI) worked with the laboratory fruit fly to find new genes involved in regulating dopamine ...

New mega-analysis reveals why memory declines with age

2026-01-13
A landmark international study that pooled brain scans and memory tests from thousands of adults has shed new light on how structural brain changes are tied to memory decline as people age. The findings — based on more than 10,000 MRI scans and over 13,000 memory assessments from 3,700 cognitively healthy adults across 13 studies — show that the connection between shrinking brain tissue and declining memory is nonlinear, stronger in older adults, and not solely driven by known Alzheimer’s-associated genes like ...

Understanding ammonia energy’s tradeoffs around the world

2026-01-13
Many people are optimistic about ammonia’s potential as an energy source and carrier of hydrogen, and though large-scale adoption would require major changes to the way it is currently manufactured, ammonia does have a number of advantages. For one thing, ammonia is energy-dense and carbon-free. It is also already produced at scale and shipped around the world, primarily for use in fertilizer. Though current manufacturing processes give ammonia an enormous carbon footprint, cleaner ways to make ammonia do exist. A better understanding of how to guide the ammonia fuel industry’s continued development ...

UTHealth Houston researchers map gene disruptions in sporadic early onset Alzheimer’s disease across key brain regions

2026-01-13
A new study led by researchers at UTHealth Houston investigated both gene expression and regulation at single cell levels to reveal disruptions in gene function in three brain regions of patients with sporadic early onset Alzheimer’s disease. The findings were published in Science Advances. Only about 5% to 10% of patients with Alzheimer’s disease are younger than 65. Of those patients, 10% have mutations in the APP, PSEN1, and PSEN2 genes, which are associated with Alzheimer’s disease. The other 90% of these cases are classified as sporadic early onset Alzheimer’s, a rare and aggressive form of the ...

Minimum wage increases are linked to safer pregnancies

2026-01-13
Increases to the minimum wage may do more than bolster household income, reduce inequality and enhance worker well-being: They may also help make pregnancies safer, according to new research from Rutgers University. A study published online ahead of the Fe in the American Journal of Preventive Medicine finds that state-level increases in the minimum wage are associated with lower rates of hypertensive disorders of pregnancy, a leading cause of maternal mortality in the United States. The study, led by Slawa Rokicki, an assistant professor at the Rutgers School of Public Health, ...

Left in the cold: Study finds most renters shut out of energy-saving upgrades

2026-01-13
As winter heating costs rise, new research from Binghamton University, State University of New York reveals a cold truth. Renters – who make up approximately ⅓ of the U.S. population – are missing out on energy efficiency improvements that could lower their bills, make their apartments more comfortable and improve their health. This study, “Still muddling through: Local sustainability leaders and energy efficiency in rental units,” was published in Energy Research & Social Science. ...

Researchers from The Grainger College of Engineering at the University of Illinois Urbana-Champaign have reported the first observation of a dynamic magnetochiral instability in a solid-state material. Their findings, published in Nature Physics, bridge ideas from nuclear and high-energy physics with materials science and condensed matter physics to explain how interplay between symmetry and magnetism can amplify electromagnetic waves. A material’s behavior is heavily influenced ...

Organisms in the Atacama Desert soil are remarkably diverse

2026-01-13
A new study shows that resilient and remarkably diverse populations of organisms can persist in the soil despite harsh and extremely dry conditions. An international team led by researchers from the University of Cologne, has examined tiny nematodes in the Chilean Atacama Desert. Along with the polar regions, the Atacama Desert is considered one among these most arid regions in the world. Lack of rainfall, high salt content in the soil, and extreme temperature fluctuations make it one of the most hostile places on earth. The interdisciplinary team with researchers from the fields of zoology, ecology and botany demonstrated the strategies used by different nematodes ...
