Addiction Potential of Very Low Nicotine Filtered Little Cigars

This Phase 4 trial by Ohio State University Comprehensive Cancer Center explores how lowering nicotine in filtered little cigars might change smoking habits and lung health for adult cigar users. For patients and smokers, the study could lead to products that reduce addiction risk and exposure to harmful substances. Participants visit one site in the United States for surveys, breathing tests, and smoking sessions during the study.

Oxytocin for Respiratory Compromise and Hypoventilation Induced by Drugs

George Washington University is planning a Phase 2 trial to test if intranasal oxytocin can help prevent breathing problems caused by opioids after bariatric surgery. For patients undergoing weight loss surgery, this treatment could reduce dangerous breathing issues without affecting pain relief. The study aims to enroll 100 patients but has not yet started recruiting.

A TwiCs Study of TCM Management Based on Cardiopulmonary Screening in COPD

This study from Henan University of Traditional Chinese Medicine is investigating whether adding traditional Chinese medicine guidance to usual care benefits people who have stable COPD and signs of heart disease. For patients, this combined approach might lower the risk of heart problems and improve overall health. The trial plans to follow 200 participants aged 20 to 80 for about two years.

Comparing the Efficacy of a Conversational Agent (QuitBot) Versus Standard Health Education on Smoking Cessation Among Medical Students; A Randomized Controlled Trial

Researchers at Cairo University are testing a digital helper called QuitBot to support medical students in quitting smoking compared to regular health education. If this new tool works well, it could provide a more engaging and easy way to help young adults stop smoking. The study is currently recruiting 180 participants.

Measurement of Expiratory Flow Variability for the Detection of Bronchospasm in Infants Using the Ventica® Device by Revenio

This completed study in France looked at a new device designed to measure breathing patterns in infants and young children with wheezing or respiratory episodes. Early detection of bronchospasm using this non-invasive tool may help families and doctors monitor lung health without complicated tests. Results are still pending for children aged 2 months to 3 years.

This week saw trials exploring ways to reduce smoking addiction, improve breathing safety after surgery, and better detect lung problems in young children. These studies reflect ongoing efforts to make respiratory health easier to manage and safer for patients.
