Cough may warn of danger for patients with lung-scarring disease

19.10.2011
A new analysis has found that coughing may signal trouble for patients with the lung-scarring disease known as idiopathic pulmonary fibrosis. The study, published in the journal Respirology, found that patients with the condition who also cough are more likely to develop advanced forms of the disease that may be life threatening.

When idiopathic pulmonary fibrosis develops, tissue deep in the lungs becomes thick and scarred, likely due to a response to an unknown substance. The condition affects approximately 100,000 individuals in the United States, and up to half die within three years of being diagnosed.

Almost all patients with idiopathic pulmonary fibrosis experience shortness of breath. The second most common symptom is cough. Shortness of breath is a known warning sign that a patient has a serious form of the disease, but little is known about the importance of cough.To investigate, Christopher Ryerson, MD, of the University of California, San Francisco, and his colleagues studied 242 patients with idiopathic pulmonary fibrosis. They found that cough was present in 84% of patients. It was more common in patients with advanced disease and in those who had never smoked. Also, the presence of cough predicted more rapid disease progression, regardless of the severity of a patient's disease. The study's findings indicate that the presence of cough may predict which patients are likely to die prematurely or need a lung transplant in the near future.

The authors concluded that patients with idiopathic pulmonary fibrosis who cough may have a worse prognosis compared with patients who do not cough. While additional studies are needed to validate the results, patients who cough may benefit from closer monitoring and more aggressive treatments.

"These findings improve our understanding of cough in idiopathic pulmonary fibrosis," said Dr. Ryerson. "The reason for the association between cough and never having smoked is unknown, but may provide insight into the pathogenesis of cough in idiopathic pulmonary fibrosis and thus prompt future research in this area," he added.

Im Focus: Turmoil in sluggish electrons’ existence

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...

Im Focus: Using graphene to create quantum bits

In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.

In pursuit of this goal, researchers at EPFL's Laboratory of Photonics and Quantum Measurements LPQM (STI/SB), have investigated a nonlinear graphene-based...
