Emphysema is a debilitating disease that afflicts more than three million Americans. The disease is caused primarily by smoking and leads to a progressive, irreversible breakdown of lung tissue.
Emphysema Pathophysiology, Causes, Diagnosis & Treatment
Emphysema is a chronic or long term lung disease. This disease is typically called hyperinflation.
Emphysema is a progressive, debilitating lung disease in which the lung's breathing sacs, or alveoli, enlarge, get thinner, and eventually are destroyed as the cells die off. It can be fatal, and there is currently no cure.
Aspergillus latus, a species of fungus previously found only in soil or plants, has been found for the first time in a hospital environment by an international group of researchers.
Three hours of weekly strength training combined with protein supplements leads to both bigger and stronger muscles in patients with cirrhosis. This is shown by a new study from Aarhus University and Aarhus University Hospital.
A new study of lung anatomy may explain why 1 in 4 cases of COPD--a lung disease most often linked to smoking--occur in people who have never smoked, a fact that has long perplexed researchers.
Researchers at Kumamoto University in Japan have discovered that uric acid, an antioxidant, protects against declining lung function from age or lung disease, especially in women.
Chronic obstructive pulmonary disease (COPD), which includes chronic bronchitis and emphysema, is a chronic lung disease that makes it hard to breathe. The disease affects millions of Americans and is the fourth leading cause of disease-related death in the U.S. People with COPD have a higher risk of more severe illness from COVID-19 due to their existing lung problems.
With many hundreds of thousands of deaths due to the current COVID-19 pandemic, there is a rush to find an effective vaccine or drug against the virus. A new study on the preprint server medRxiv* in May 2020 shows that the use of some biologically plausible drugs may be counterproductive, and care should be taken when trying out unproven therapies.
The COVID-19 pandemic caused by the severe acute respiratory syndrome -coronavirus 2 (SARS-CoV-2) has spread to most of the world, causing millions of cases and hundreds of thousands of deaths. A new study published on the preprint server bioRxiv* shows that a protease inhibitor drug already approved by the Food and Drug Administration (FDA) could inhibit viral entry.
Diagnosing emphysema and classifying its severity have long been more art than science.
News-Medical speaks to Professor Don Sin on his research into COVID-19 and its effect on smokers and people suffering from COPD.
Smoking tobacco may aggravate the effects of coronavirus disease (COVID-19). Health experts are urging smokers to quit and cigarette companies to stop producing tobacco products to help alleviate the risks of COVID-19. A new study from China highlights the risk of smoking during the coronavirus pandemic.
A UK study of patients participating in low-dose CT lung cancer screening highlights the importance of spirometry (breathing tests) in the assessment of possible chronic obstructive pulmonary disease (COPD), and demonstrates that over-reliance on radiological changes alone may result in detection of clinically insignificant disease.
Cardiologists at The Ohio State University Wexner Medical Center are the first in the United States to test a new type of ablation technology for patients suffering from atrial fibrillation, a common type of irregular heartbeat.
Researchers have managed to radiologically view the novel coronavirus infected individuals, and this could be a step towards early detection of this virus and diagnosis of those infected by it. The study titled, “CT Imaging Features of 2019 Novel Coronavirus (2019-nCoV),” was published this week in the journal Radiology.
It’s never too late to quit smoking, as a new study shows the lung’s ability to heal and regrow damaged cells caused by cigarette smoking, even if they smoked for decades.
A new study could explain how lung cancer risk is reduced by quitting smoking. Published in the journal Nature in January 2020, the study shows that ex-smokers have a greater number of lung cells that have healthy genes compared to current smokers. Healthy genes are less likely to transform into cancerous cells.
We live in an era of self-empowerment. But when it comes to quitting smoking, going it alone isn't the best approach.
Using data from a large federal government telephone survey of adults, Johns Hopkins Medicine researchers report evidence that inhaling heated tobacco vapor through e-cigarettes was linked to increased odds of asthma and chronic obstructive pulmonary disease, conditions long demonstrated to be caused by smoking traditional, combustible cigarettes.
Over many years, exposure to the levels of ozone and other forms of pollution found in most U.S. cities and some rural communities can take a toll on a person's health.
A new study has revealed that use of electronic cigarettes is associated with a raised risk of developing chronic lung diseases such as asthma, bronchitis, chronic obstructive lung disease (COPD) or emphysema.
