Every month I try to read an open-access article. After reading the article, I share the title and associated link with my followers. This is to encourage clinicians to read articles, stay up to date, and continue to grow.

This month I found a great piece to share with you.  This one is about chronic bronchitis. The objective of this paper is to “assess the prevalence of chronic bronchitis in young adults in a Swedish population-based birth cohort and to identify early-life risk factors, including environmental exposures, for disease development” (p2).

3 Reasons why I found this article interesting

  • Authors comment on the impact of cigarette and e-cigarettes and chronic bronchitis in young adults (direct and indirect). Also, authors included factors such as breastfeeding as a protective factor which is something I would not have immediately thought of.
  • It includes a 24-year follow up assessment. They have excluded asthmatic patients to make their observation more accurate.  Various assessment tools were included, including self-assessments, pre and post spirometry, and FeNO2. 
  • This study reminded me that this condition “may exist with our without airway obstruction” p7.

What’s your experience with chronic bronchitis in young adults? Have you noticed a pattern?

Happy learning and reading!

This month I found a great piece to share with you.  This one is a prospective, open-label, single-arm study. The objective of this paper is to “evaluate the feasibility, efficacy and safety of metered cryospray therapy to treat patients with chronic bronchitis in COPD”  p3.

Reasons I found this article interesting 

  • I didn’t know about metered cryospray therapy (MCS) and this article introduced me to its application in chronic bronchitis. Its intent is to “cryoablate abnormal epithelium and excessive mucous-producing goblet cells” p2.
  • The method of application is clearly explained in this article.  On page 3, the authors explain the three treatments and which lobes and airway pathways received the MCS therapy in each of those treatment sessions. 

While I am still unsure about the safety of this therapy until further research and improvements are done, I enjoyed learning about the unique approach.  I say this as the sample was only 34 subjects.  Also, “no definitive histological differences were observed between baseline and day 60 endobronchial biopsies” p10. 

If you were not aware of this therapy, this may be a good article for you to read. If you have applied this therapy in the past, I would love to hear about your thoughts and experiences.  Leave a comment and let me know!

Happy learning!
