The study found the presence of the metals molybdenum and vanadium along with sulfate -- a collection of mineral salts -- in the U.S. municipal water system was associated with an increased incidence of NTM pulmonary infections, the leading cause of drinking-water associated illnesses.

According to new research, this form of medication improves the symptoms of CF in many patients.

If the airways then fill with fluid, the patient risks developing acute respiratory distress syndrome. Researchers have now discovered the molecular mechanisms that trigger fluid accumulation in the lungs. This also led them to discover a potential new therapy: A cystic fibrosis drug proved effective in their laboratory experiments, raising hope that this could be used to treat pneumonia regardless of the pathogen that caused it.

A new combination drug therapy which addresses the disorder's underlying defects offers a promising new treatment approach. The use of this therapy had previously been limited to adolescents and adults. Designed to meet the highest standards of clinical practice, a study has now confirmed that this combination therapy regimen is also beneficial to primary school-aged children. Earlier treatment means disease progression is likely to be significantly slowed.

While there are many hundreds of known mutations, not all of them are currently treatable which means a significant number of CF patients lack targeted therapies. In an effort to identify new treatments for these patients, researchers from Boston University School of Medicine (BUSM) set out to use blood cells from individuals with CF to make patient-specific induced pluripotent stem cells (iPSCs) and generate lung epithelial cells in the lab. These lung cells are functional and highly similar to the lung cells of the patient. Using these 'lung cells in a dish,' they have created a novel platform to discover effective drugs for those patients who currently don't have any treatment options.

Scientists have discovered a new way ASOs may help cells produce a protein missing in cystic fibrosis (CF) patients. The discovery sets the stage for a new therapeutic approach that may help reduce CF symptoms and improve patients' quality of life.

In particular, patients suffer from chronic bacterial infections that can lead to respiratory failure. It is caused by mutations in the CFTR gene, which regulates water movement across the cell membrane. Consequently, mucus quality is altered, it is no longer capable of capturing undesirable bacteria and expelling them. Using a model reproducing a respiratory epithelium -- a protective tissue composed of a monolayer of cells -- scientists have discovered that a simple film of liquid is sufficient to restore the airways' seal and reduce the risk of bacterial infection.

A major barrier to developing new and urgently needed treatments is the lack of human in vitro models that recapitulate the CF disease's pathology. Fri, 19 Nov 2021 15:52:30 EST //www.koonmotors.com/releases/2021/11/211119155230.htm //www.koonmotors.com/releases/2021/10/211021175118.htm In the largest study of its kind, researchers found that the lower airways in children with cystic fibrosis (CF) have a higher burden of infection, more inflammation and lower diversity of microorganisms, compared to children with other illnesses who also have lung issues. They noted a clear divergence in these bacterial communities in toddlers, which is typically before progressive lung disease takes hold in patients with CF. Their findings could help providers target specific pathogens earlier, treat them and potentially prevent more severe lung disease.

So rather than targeting red herring mutations, researchers suggest paying attention to patterns of genomic adaptation versus erosion, which might better indicate a viable path towards the more effective therapeutics for cystic fibrosis.

Infections develop, leading to severe chronic disease and early death. Now, for the first time, scientists have shown why coughing often cannot tear mucus apart and away from the airway lining. And they showed how to make mucus thinner and less sticky so coughing can become a therapeutic aid.

Sound familiar? Two studies now give explanations: First, crucial mechanisms of the mucus in both diseased and healthy airways; second, what happens in such chronic lung diseases as cystic fibrosis and chronic obstructive pulmonary disease (COPD).
