Round 1

Reviewer 1 Report

Present manuscript provides systematic review about impact of homocysteinemia in brain injured neurocritical-care patients. There are some minor problems that have to be fixed:

Some expressions are confusing. For example, Although Hcy is not directly involved 37 in protein synthesis, its role in folate metabolism and choline catabolism is fundamental 38 to regulate Met activity and for the synthesis of several proteins: its ability to donate me-39 thyl groups is essential for the synthesis of methylated compounds, while the inorganic 40 sulfate is pivotal for the synthesis of sulfur-containing amino acids.

Fig. 1 is incomplete. Serine as acceptor of sulfur is missing in transsulfuration reaction.

Discussion describing impact of vitamins B6 and B12 as well as the impact of folic acid is not well arranged and should be modified.

Reviewer 2 Report

The authors aimed to elucidate the relationship between plasmatic homocysteine concentratin and acute brain injury in neurocritical-care patients. A systematic review was conducted on 22 existing literatures on acute ischemic stroke, traumatic brain injury, intracranial hemorrhage, and subarachnoid hemorrhage. However, the scope of 'neurocritical-care patients' included in the study is too broad. In addition, the end points used to indicate poor prognosis in each study are so heterogeneous that it is difficult to draw a unified result by comparing the results of each study.
