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 piece on cardiopulmonary exercise capacity and COVID19 recovery. The objective of this paper is to “determine cardiopulmonary function during exercise 3–4 months after hospital discharge for COVID-19 compared with a reference population and to describe the characteristics of participants with exercise limitations. ” p2.

The reasons I found this article interesting 

  • Regaining exercise capacity after COVID-19 is an important finding (p7).
  • Brings more weight to self-reported dyspnea as it was “associated with lower ventilatory efficiency and lower V′O2peak·kg−1 due to higher BMI” (p7).
  • In order of relevance: deconditioning, circulatory factors, and ventilatory limitation were the top three exercise limitations (p7).

This is a great article so I encourage you to take the time to read it.  

Happy learning and reading!

The objective of this paper is to use the “data from the INMARK trial to assess the feasibility and validity of home spirometry as a measure of lung function decline in subjects with IPF “ p2.

Reasons you may find this article interesting 

  • I like the idea of patients with chronic conditions being able to perform spirometry at home.  I value the time and technology advancement to make these tests available at home, and having the ability to remotely tracking patients’ progress. This empowers patients to be more aware of their health status and to be more conscious of their well being.
  • Authors conclude that there is a “strong correlation where observed between FVC measurements abstain at home and in clinic at individual time-points, but correlations between changes in FVC measurements over time estimated using home and clinic spirometry were weak, mainly due to variability in the measurements obtained using home spirometry” p8. (side note: researchers did provide re-training as required). I encourage you to read the full article to view all the details.

This month I found a narrative review to share with you.  The objective of this paper is to “  to review detached opinions and provide strategies for the safe and effective delivery of aerosolized medications through HFNC in the era of COVID-19 and beyond.” [p22].

The reason you may enjoy this article

  • The authors have put together a nice summary of suggestions with regards to:
    •  Nebulizer selection, 
    • Nebulizer placement and use, 
    • HFNC cannula prongs, 
    • Gas flow, 
    • Delivery technique, and 
    • Unit dose vs. continuous nebulization with an infusion pump.

This month’s article falls under infection and lung function. The objective of this paper is to “systematically evaluating the persisting cardiopulmonary damage of COVID-19 patients 60 days and 100 days after COVID-19 onset” (p2).

Reasons you may find this article interesting 

  • I have noticed a trend of increased referrals for patients with past diagnoses of COVID19.  As the local rates for the virus decreases, patients and ordering physicians have felt more confident sending patient to the outpatient PFT lab of the hospital.  This is another useful article to better plan and look after such patients. 
  • While this study has its limitations such as 
    • being specific to Austria, 
    • includes individuals with existing comorbidities, and 
    • lacks pre-infection diagnostic testing, 

      However, it still delivers a lot of useful information.  The study includes questionnaires, PFT, cap. Gas samples, TEE, CT and other routine lab examinations (p3).  I strongly recommend that you look over each component in the results section: Clinical Evaluation at follow-up, Cardiopulmonary evaluation at follow-up, Serological Markers, and Pulmonary Imaging (pp 4-6).

This month I found a great piece to share with you.  This one falls under the infection and lung function categories. The objective of this paper is to “ [assess] patient-reported dyspnoea, lung function, quality of life (QoL) and parenchymal opacities in chest CT scans 3 months after hospital admission for COVID-19 in a prospective, consecutive Norwegian cohort of patients with or without ICU treatment. ” [p2].

Why this article caught my attention:

  • It helped me have a better understanding of the recovery process of individuals with COVID19.  There will be a lot of focus on the recovery and rehab of patients once we are done with the peak of this pandemic.  
  • Includes valuable information as it focuses on symptoms and various diagnostic data which includes PFT and CT scans! Check out page 3 and also Table 2 on page 5 for more information

I really hope that more studies like this will be conducted on our COVID19 patients.

How are you preparing for COVID19 Rehab? Which set of data and recommendations are you using?
