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.
The impact on lung cells of Heat not Burn products--a hybrid between traditional cigarettes and electronic vaping devices--may be no less harmful than that of conventional cigarettes, suggest the findings of a small comparative study, published online in the journal Thorax.
X-rays, first used clinically in the late 1890s, could be a leading-edge diagnostic tool for COVID-19 patients with the help of artificial intelligence, according to a team of researchers in Brazil who taught a computer program, through various machine learning methods, to detect COVID-19 in chest X-rays with 95.6 to 98.5% accuracy.
A team of engineers has identified the 'violent' physical processes at work inside the lungs which cause wheezing, a condition which affects up to a quarter of the world's population.
Researchers at the National Institutes of Health and their collaborators found that inhaling unfragmented hyaluronan improves lung function in patients suffering from severe exacerbation of chronic obstructive pulmonary disease (COPD).
Chronic pain can be quite common among older adults as they face conditions such as arthritis and neuropathy. Treating pain in older adults requires special considerations, however, especially when it comes to opioids.
In a controlled study of smokers, nonsmokers, and e-cigarette users, University of North Carolina School of Medicine researchers found that e-cigarette users exhibited significantly altered immune responses to a model of influenza virus infection, suggesting increased susceptibility to disease.
A growing body of evidence points to the health risks of using e-cigarettes (or "vaping"). But because e-cigarettes are marketed as a less harmful alternative to traditional cigarettes, it has been difficult to tell whether the association between vaping and disease is just a matter of smokers switching to vaping when they start experiencing health issues.
About 30 years ago, Dr. Richard Sifers set out on a journey to discover why people with a rare condition known as alpha1-antitrypsin deficiency present with high variation in the severity of liver disease.
Midwesterners aren’t known for complaining. But after Mercy Hospital Fort Scott closed, hardship trickled down to people whose lives were already hard.
Now, American researchers have looked at all reported cases of re-infection and the possible reasons behind them. Their study titled, “Re-infection with SARS-CoV-2 and Failure of Humoral Immunity: a case report,” is published online on the preprint server medRxiv in September 2020.
What do vapers, smokers, and non-smokers with chronic conditions such as high blood pressure or diabetes have in common? They all are at higher risk for COVID-19.
Each cigarette smoked a day by heavier smokers increases the risk of contracting some diseases by more than 30 per cent, according to a new international study published today.
Smoking has been linked to a higher risk of bone fractures. Researchers have now identified certain lung-related factors that may help to predict an individual smoker's fracture risk.
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.
