New cough science publications vetted and collected in one place
Key Takeaway: The results are promising! On a small sample size, the investigated AI model showed good performance in basic pulmonary function parameters - FEV1, FEV1%, FEV1/FVC, FVC, and FVC%.
Why It Matters: The standard method for evaluating pulmonary function, spirometry, is complex and hard for patients to self-test accurately. AI analysis of cough sounds could replace or complement this with non-invasive monitoring for faster, higher-quality insights into disease progression.
Key Takeaway: Dry and polluted air exacerbates osmotic pressure differences across mucus that are pivotal in transpiration. This potentially leads to increased ATP levels, inflammation, acidity, and changes in the permeability of mucus water - a ‘cascade of events’ that is believed to contribute to cough hypersensitivity.
Why it Matters: By better understanding and addressing the root causes of mucus transpiration – reaction to dry and polluted air – more effective and targeted therapies might be developed, offering relief for chronic coughers.
Key Takeaway: Combining overnight audio recordings of cough and other nonverbal vocalizations with spirometry data resulted in a 30% improvement in FEV1 forecasting.
Why It Matters: Additional audio data, collected non-intrusively via a bedside smartphone, could lead to a more comprehensive view of an asthma patient’s condition, paving the way for more tailored and effective asthma management strategies.

Exploring the Possibilities of Longitudinal Cough Data
Could esophageal dysmotility be a cause of cough hypersensitivity syndrome?
“This work is important for a multitude of different patients who suffer from chronic cough… [and] we hope to delineate a common pathology of esophageal dysmotility in these conditions and present a simple way to optimize the management of such patients.”
We spoke with Dr Sykes to know more about his current clinical trial that is examining the effect of azithromycin on cough in patients with a multitude of chronic respiratory diseases. This is the first trial ever to integrate continuous longitudinal cough data with esophageal manometry.
