This study looked at 250 people to understand why some smokers develop a rare lung condition called combined pulmonary fibrosis and emphysema (CPFE). Researchers compared telomere length and genetic mutations in patients with CPFE, those with only fibrosis or emphysema, and healt…

This study tested whether having a dietitian help patients with lung disease order meals during a hospital stay could improve their nutrition and reduce the chance of being readmitted after discharge. 41 patients at nutritional risk took part. Researchers measured daily food inta…

This study tested whether a device called MYOTRACE, which measures how hard a person's breathing muscles are working, can help doctors assess patients with respiratory diseases. 56 adults with conditions like COPD or asthma were included. The goal was to see if the device's readi…

This early-stage study tested a new drug called AZD8965 in 147 healthy adults, including Japanese and Chinese participants. The main goal was to check if the drug is safe and how the body processes it, both with and without food. No treatment was given for any disease, so this st…

This completed study looked at how the antibiotics amoxicillin and clavulanic acid get into the infected fluid around the lungs in people with pleural infections. Eleven adults with complicated infections had chest tubes placed and received the antibiotics. Researchers measured a…
