Digital inhalers may detect early warning signs of COPD flare-ups
Digital inhalers can monitor changes in how much air is inhaled, duration of inhalation
2025-06-17
(Press-News.org) Miami (June 17, 2025) – Digital inhalers may help predict impending acute exacerbations of chronic obstructive pulmonary disease (COPD), according to a new study. The study is published in the May 2025 issue of Chronic Obstructive Pulmonary Diseases: Journal of the COPD Foundation, a peer-reviewed, open-access journal.
COPD is an inflammatory lung disease, comprising several conditions, including chronic bronchitis and emphysema, and can be caused by genetics and irritants like smoke or pollution. The disease affects more than 30 million Americans and is the fourth leading cause of death worldwide.
Exacerbations, or flare-ups, can cause accelerated loss of lung function, a decrease in quality of life, and reduce a person’s physical function and activity. More than 50% of people with COPD experience at least one acute COPD exacerbation within four years of an initial COPD diagnosis. Increased respiratory rates and decreased lung volumes are early signs of an exacerbation.
This new study examines how digital inhalers using remote monitoring data can help predict and identify early or impending COPD exacerbations. The digital inhaler used in this study measured peak inspiratory flow, inhalation volume, inhalation duration, time to peak inhalation, and inhaler use. The study examined whether the data collected by the digital inhaler could identify a possible early-stage exacerbation.
“While this study examined a small group of participants, the remote monitoring data showed people experienced significant decreases in the amount of air they inhaled and how long that inhalation lasted in the approximately two weeks prior to experiencing an exacerbation,” said M. Bradley Drummond, M.D., MHS, professor of medicine in the Division of Pulmonary Diseases and Critical Care Medicine at the University of North Carolina, Chapel Hill School of Medicine and lead author of the study. “As these remote monitoring technologies get more advanced, we can help both patients and health care providers identify exacerbations earlier, which allows us to provide better exacerbation management and improve health outcomes.”

Living close to cyanobacterial harmful algal blooms — which are present nationwide but are more common in coastal and Great Lake states — heightens the rate of dying from amyotrophic lateral sclerosis, or ALS, a study suggests.
These blooms occur when cyanobacteria, also called blue-green algae, grows dense and out of control, producing toxic agents that can poison people and the environment.
Researchers at Michigan Medicine surveyed participants with ALS who were seen at the University ...

Background and objectives
Propolis is a resinous material produced by honeybees. Its chemical composition is highly complex and varies significantly depending on geographic region and season. This intrinsic variability presents challenges to the standardization and quality control of propolis. This study aimed to evaluate the chemical composition, total phenolic content, and antioxidant potential of propolis collected from seventeen geographical regions across Africa.
Methods
A reverse-phase high-performance ...

New York, NY [June 17, 2025]—In a new collaboration that could transform how cancer is treated, OCCAM Immune—a Mount Sinai initiative focused on understanding the immune system’s role in disease—is partnering with the Cancer Research Institute (CRI) to unlock the secrets of how the immune system responds to advanced therapies.
Under the agreement, OCCAM Immune and CRI have established a long-term plan to support ongoing immune monitoring across CRI’s clinical trials. The collaboration ...

Suicide remains one of the most pressing public health crises affecting young adults today, with devastating consequences. According to the United States Centers for Disease Control and Prevention, suicide is currently the third leading cause of death among individuals aged 18 to 25, with a 51% increase in suicide deaths between 2000 and 2021.
While this trend is deeply concerning for the general population, it is even more alarming for young adults living with intellectual and developmental disabilities (IDD) – a group long overlooked in suicide prevention efforts.

In recent years, Mendelian randomisation (MR) has revolutionised observational epidemiology by offering a tool to infer causal relationships using genetic variants as instrumental variables (IVs). However, its popularity has come at a cost. The editorial by Chen, Guillot, and Schneider in eGastroenterology (2025) titled "Attention to the misuse of Mendelian randomisation in medical research" delivers a timely critique of the field's current trajectory. As MR studies surge, so too do concerns about their quality and interpretive validity. The authors call for stricter methodological scrutiny and offer practical recommendations ...

AI can help public health agencies in the quest to end HIV. The United States is pursuing an initiative to end the HIV epidemic by 2030. To achieve this goal, public health agencies and organizations must remind the public about how best to avoid transmitting and acquiring the virus. Public health campaigns are costly, their effectiveness is seldom systematically assessed, and no systematic methods have been developed to build health campaigns in real-time. Dolores Albarracin and colleagues collected public health messages about HIV prevention and testing from US federal agencies, non-profit organizations, ...

Gene editing could be used to treat millions of glaucoma patients. Glaucoma is a leading cause of blindness, characterized by high pressure inside the eye. Patients often rely on daily eye drops to lower intraocular pressure, but the drops may cause significant complications including bradycardia, metabolic acidosis, and kidney stones. In addition, many patients fail to keep up with the eye drops. Yang Sun and colleagues used the CRISPR gene editing technique to knock down two genes associated with the production ...

Bees, ants and termites don’t need blueprints. They may have queens, but none of these species breed architects or construction managers. Each insect worker, or drone, simply responds to cues like warmth or the presence or absence of building material. Unlike human manufacturing, the grand design emerges simply from the collective action of the drones — no central planning required.
Now, researchers at Penn Engineering have developed mathematical rules that allow virtual swarms of tiny robots to do the same. In computer simulations, the robots built honeycomb-like structures without ever following — or even being able to comprehend — ...

A public survey indicates that Americans have negative opinions of scientists who work on AI. Dror Walter and colleagues collected opinions about scientists from thousands of US adults via the Annenberg Science and Public Health survey and compared the perceived credibility, prudence, unbiasedness, self-correction, and benefit of scientists working on AI with those of scientists in general and climate scientists in particular. Previous work has established that high scores on these dimensions predict support for science ...

A new McGill University-led study suggests that disrupting the body’s internal clock during adolescence can alter how the brain responds to an in-utero risk factor linked to certain brain disorders.
Previous research has shown that a mother’s infection during pregnancy, such as the flu, can increase a child’s risk of developing conditions like schizophrenia and autism spectrum disorders later in life. Irregular sleep patterns – often a sign of circadian rhythm disruption – are also associated with these conditions.
To investigate how these factors interact, researchers exposed mice to either a ...
