Authors are strictly instructed to follow Vancouver system for citing scientific literature. Any manuscript reference not following Vancouver system will immediately be sent back to author for revision. Authors can get a comprehensive explanation of the system with practical examples in the following link:

Authors must also note that NHJ follows following variation in Vancouver style:

  1. Superscripts must be used rather than brackets.
  2. Numbers (citations) should be inserted before colons and semi-colons. (to the left)
  3. Numbers (citations) should be inserted after comas and full stops. (to the right)
  4.  It is important that the punctuation and form is consistently applied to the whole document.

These are commonly used abbreviations to write in reference list
c. = circa (about, approximately) ed. = edition
fig; figs = figure(s) p. = page(s)
pt pts = part(s) suppl= Supplement
ch. = Chapter et al.. = and others
ill ills = illustrator(s) para paras = paragraph(s)
rev = revised

The decision of the editor will be final for modification or rejection. However, the author may withdraw his/her manuscript prior to publication when given a chance by the editor (e.g. after modification).

If the authorship of a paper is changed in any way after it has been reviewed, the Editor will require a letter, signed by all authors named on the original or on the revised submission, explicitly agreeing to the change.

Additional prints/ republication/ translation.
As NHJ is an Open Access Journal and we post all the articles published in the web in PDF format, the author may print additional copies. However, for doing so the author has an obligation to inform NHJ. This will also help us in tracking reprinted articles. However, if the quantity of reprints required is more than 50 or in a commercial basis, prior written permission is required by the author from the Chief Editor of NHJ.

For republication of the article in another journal, the author must seek prior permission from NHJ, clearly stating the purpose and request for permission to print again.

For translation of the article and publication in another language (in another journal), the author must seek prior permission from NHJ along with the purpose and request for permission to print again. Both the above mentioned points require to be compliant with ICMJE guidelines for reprints and translation.

The submitted manuscript should actually represent the scientific work done and the data should not be manipulated for whatsoever purpose.

Any irregularities, misinformation, or manipulation of the data tending to skew the conclusion towards the side that does not represent the actual finding, if found, can result in the manuscript to be rejected or retracted (if already published). NHJ may proceed with legal actions if needed in appropriate cases.

If authors of a published article subsequently become aware of a significant error in it, they should send a notifying letter to the editor of NHJ as soon as possible. If the mistake is judged significant enough to warrant a published correction, the correction will be made as an “erratum” if the fault is NHJ; “correction” if the fault is the author’s.
