Review Data

Q: Is the topic relevant to the journal area of interest? Is it contemporary and interesting for


A: Good


Abstract & Keywords

Q: Are all required components included in the abstract? Are the keywords appropriately chosen?

A: Good



Q: Is the goal explicitly stated in the Introduction? Is its formulation clear and unambiguous?

Tools and Methods

Q: Are methods the author uses adequate and well used?

A: Good


Discussion & Conclusion

Q: Is it related to the results presented before? Do you consider them as coherent?

A: Good


Comments: The Discussion gives an overview of the cohort study undertaken to show the efficiency of ECMO cannulation among COVID-19 and obese patients providing relevant literature. Moving forward, the Discussion highlights the limitations of the study conducted. Lastly, it suggests that the utilization of ECMO for COVID-19 patients associated with acute respiratory distress syndrome (ARDS), subsets should be considered, and outcomes should be further investigated.



Q: Does the author utilize relevant literature?

A: Good

Q: What is the level of the author’s knowledge? Does the author utilize all recent contributions relevant to the topic?

A: Good



Q: Is the length of the paper adequate to the significance of the topic? Do you suggest shortening the paper without losing its value?

A: Good


Writing style

Q: Is it clear and understandable?

A: Good

Comments: There are few errors found in the manuscript which are as follows:

·       In Introduction, 2nd paragraph, 1st sentence, Obese patients are at high risk … in motrality in critical ill obese patients” must be written as “Obese patients are at high risk … in mortality in critically ill obese patients”.

·       In Results, 1st paragraph, 3rd sentence, “Fifty five percent (n=11) were female, two of which were pregnant” can better be written as “Fifty-five percent (n=11) were female, two of whom were pregnant”.

·       In Discussion, 4th paragraph, 2nd sentence, “Our cohort not only contributes to the existing literature demonstrating a relatively low mortality in patients who receive ^d ECMO support … ARDS, but is hypothesis …” is rewritten as “Our cohort not only contributes to the existing literature demonstrating relatively low mortality in patients who received ECMO support … ARDS but hypothesis …”.


Further comments on the paper

Comments: The manuscript illustrates a retrospective cohort analysis of ECMO cannulation criteria in COVID-19 and obesity. The research further describes the importance of Veno-Venous Extracorporeal Membrane Oxygenation (V-V ECMO) in rescue therapy in patients with acute respiratory distress syndrome (ARDS). The findings of this research revealed high survival in hospital discharge and demonstrated non-inferior outcomes and survival in obese patients. The manuscript also discusses the methods used in the research and establishes retrospectively reviewed demographic, clinical, and diagnostic data obtained during each patient’s admission. The results and outcomes of the study are discussed thoroughly.


Q: Would you recommend this manuscript for further publication?

A: Yes - Suitable to be published

If you have any questions and clarifications you can write to the journal.
