Editorial urges deeper focus on heart-lung interactions in pulmonary vascular disease

2025-08-01
(Press-News.org)  

DENVER - A new editorial published in Comprehensive Physiology underscores the critical importance of understanding heart-lung interactions in pulmonary vascular disease (PVD). Tim Lahm, MD, a pulmonologist and researcher at National Jewish Health, along with a team of esteemed colleagues from institutions across the country, urges the scientific community to confront the major knowledge gaps that hinder progress in improving patient outcomes. The editorial, titled "Towards a Better Understanding of Heart-Lung Interactions in Pulmonary Vascular Disease,"(Opens in a new window) serves as a call for papers for an upcoming special issue of Comprehensive Physiology dedicated to this topic.

“We’ve moved beyond the idea that pulmonary hypertension is simply a lung disease,” said Dr. Lahm. “The survival and well-being of patients depend not only on how we treat the lungs, but also on how the heart — particularly the right ventricle — adapts, responds or fails under pressure. The future of patient care lies in unraveling these cardiopulmonary dynamics.”

Drawing from a wide range of recent research, the editorial explores how the heart and lungs function as a tightly coupled unit — what the authors call a “right atrium-right ventricle-lung vascular unit.” Dysfunction in one often exacerbates problems in the other, with systemic effects that extend beyond the thorax to the kidneys, liver, brain, skeletal muscle and more.

The editorial highlights growing evidence that pulmonary hypertension, traditionally viewed as a lung-centric disorder, is actually a systemic disease marked by two-way connections among multiple organs. The authors call for an expansion of research to explore novel signaling pathways, mechanical stressors and even emerging model systems — such as heart- and lung-on-a-chip technologies and computational approaches — that can simulate real-world cardiopulmonary conditions with greater precision.

The authors issue a call for papers for basic, translational and clinical research exploring these heart-lung interactions in PVD. This request includes investigations into molecular mediators, disease phenotyping, and innovative diagnostic and therapeutic strategies tailored to sex, age, disease stage and systemic factors.

5 advances to protect water sources, availability

2025-08-01
Water is an essential requirement for life on Earth — it supports everything from cellular processes to ecosystems. Five papers published in ACS journals provide new insights to help protect natural water sources and ensure that more people have access to safe drinking water. Reporters can request free access to these papers by emailing newsroom@acs.org. Reducing salt contamination of tidal rivers. Across the globe, the saltwater portion of tidal rivers — which rise and fall with the ocean tides — has been traveling farther upstream in the last few decades. Researchers publishing in Environmental ...

Brain might become target of new type 1 diabetes treatments

2025-08-01
More than a decade ago, researchers found that an acute complication of type 1 diabetes, diabetic ketoacidosis (DKA), can be resolved with the hormone leptin, even in the absence of insulin.   An analysis published today in The Journal of Clinical Investigation explains how leptin affects the brain and how it might be used in future therapeutics.  DKA happens when the body is unable to make insulin and begins to break down fat for fuel. This can lead to a life-threatening buildup of sugar (glucose) and ketoacids in the blood. Doctors have typically administered insulin to address ...

‘Shore Wars:’ New research aims to resolve coastal conflict between oysters and mangroves, aiding restoration efforts

2025-08-01
Oysters and mangroves are both essential to protecting and restoring Florida’s coastlines that they call home, including defending them against storms. As mangrove populations are increasing due to successful restoration efforts and favorable weather, however, their strong comeback may pose unintended consequences for oysters, according to new research from UCF graduate student Katherine Harris and Pegasus Professor Linda Walters published in the Marine Ecology Progress Series. To protect Florida’s coastlines, the researchers hope their new findings can initiate efforts ...

Why do symptoms linger in some people after an infection? A conversation on post-acute infection syndromes

2025-08-01
In recent years, doctors and scientists are increasingly studying long-lasting illnesses that begin after someone recovers from an infection. Two of the most well-known examples are long COVID and myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). It has been estimated that 400 million people, globally, may have Long COVID, and nearly half of them meet criteria for ME/CFS. These conditions were often misunderstood or overlooked in the past, but that is starting to change. Researchers are now studying them as part of a larger group of illnesses called post-acute infection syndromes, or PAISs. A new review by Mass General Brigham investigator Anthony L Komaroff, ...

Study reveals hidden drivers of asthma flare-ups in children

2025-08-01
A recent multicenter clinical trial has uncovered inflammatory pathways that contribute to asthma flare-ups in children that occur despite treatment, according to findings published in JAMA Pediatrics. Eosinophilic asthma is characterized by high levels of eosinophils, a type of white blood cell involved in the body’s immune response. While eosinophils typically help fight infections, in eosinophilic asthma, they accumulate in the lungs and airways, causing chronic inflammation, swelling and damage to the respiratory system. Eosinophilic asthma is driven by type 2 (T2) inflammation, an immune response ...

Physicists decode mysterious membrane behavior

2025-08-01
Cell membranes cradle, protect, and gatekeep living cells. Membranes can even affect how a cell behaves. But membranes’ own erratic behavior has puzzled scientists for years.  Turns out, it’s all about perspective: When physicist Rana Ashkar’s team members looked at how membranes behave on the nanoscale, they were able to identify unified biophysical laws that membranes have adhered to all along.   Published in Nature Communications, these findings have significant implications for disease ...

New insights about brain receptor may pave way for next-gen mental health drugs

2025-08-01
New York, NY [August 1, 2025]— In a discovery that could guide the development of next-generation antidepressants and antipsychotic medications, researchers at the Icahn School of Medicine at Mount Sinai have developed new insights into how a critical brain receptor works at the molecular level and why that matters for mental health treatments. The study, published in the August 1 online issue of Science Advances, focuses on the 5-HT1A serotonin receptor, a major player in regulating mood and a common target of both traditional antidepressants and newer therapies such as psychedelics. Despite its ...

Melanoma ‘sat-nav’ discovery could help curb metastasis

2025-08-01
Researchers have discovered a protein which is critical for steering melanoma cancer cells as they spread throughout the body. The malignant cells become dependent on this protein to migrate, pointing to new strategies for impeding metastasis.  The protein eIF2A is generally thought to spring into action when a cell is under stress, helping ribosomes launch protein synthesis. But according to a study published today in the journal Science Advances, eIF2A has a completely different role in melanoma, helping cancerous cells control movement.  “Malignant cells that metastasize ...
