“Acta Haematologica Polonica” (AHP) is a peer-reviewed, English language, gold open-access journal. It is the official bimonthly of the Polish Society of Haematologists and Transfusiologists as well as the Institute of Haematology and Transfusion Medicine. The Journal has been associated with haematology and transfusion since 1970. AHP publishes original research articles, clinical vignettes, and reviews. "Acta Haematologica Polonica" covers areas of physiology and pathology in hematology and transfusion medicine, among other leucocytes, erythrocytes, platelets, immune system, mechanisms of hemostasis and clinical aspects of haematological malignancies. Journal publishes:  original studies, reviews, expert guidelines, short communications, clinical vignettes, letters to the Editor, and editorials.

“Acta Haematologica Polonica” (AHP) is committed to prompt evaluation and publication of submitted articles. All manuscripts together with supplementary files (if applicable), should be submitted online via the journal web page. The submission and review process is fully electronic, and submissions by e-mail or postal mail will not be accepted. Please follow the manuscript preparation directions presented. Manuscripts submitted for publication in the Journal are evaluated as to whether they present new insights into the announced topic and are likely to contribute to progress in research or to changes in medical practice. Received manuscripts are initially examined by the Journal editors. Manuscripts with insufficient priority for publication are rejected immediately to allow the authors to recognize deficiencies and submit the paper to another journal or resubmit a revised version. Incomplete submissions or manuscripts not prepared in the required style are sent back to the authors without scientific review.

If the manuscript is accepted for review, the authors will be notified electronically only with reference to the article ID number in the electronic system. Articles are evaluated by at least two outside referees who are contacted before being sent a paper and asked to return comments within the period indicated by Editors. All submitted manuscripts are treated as confidential documents, and reviewers are instructed to treat manuscripts as such. The peer review process is also confidential, and the identities of reviewers are not released. Referees are asked to provide a written review together with the recommendation of acceptance, requirement for revision, or rejection of the article.

Authors are notified of decisions by e-mail only. Selected papers are edited to improve accuracy and clarity, and length. Criteria for acceptance of manuscripts or review forms are available at the Journal web page. AHP operates with a  “double-blind” peer review policy, meaning that reviewers of papers won’t get to know the identity of the author(s), and the author(s) won’t get to know the identity of the reviewer. The idea is that everyone should get a similar and unbiased review. The list of reviewers cooperating with the Journal is announced once a year. In potential cases when author(s) of manuscripts and reviewers are no more anonymous, reviewers are asked to confirm in writing no conflict of interests, i.e., no direct personal relationships (first- and second-degree kinship, legal ties, relationship by marriage), superior/subordinate professional relations or direct scientific cooperation within the two years preceding the review. Papers submitted to AHP but not accepted for publication may, in some cases, be eligible for publication in other journals of the Publisher.

Editors or Editorial Board members may submit their own manuscripts for possible publication in AHP, but they are completely excluded from the peer–review process and publication decisions when they are authors or co-authors of a manuscript. Manuscripts authored by a member of Journal’s editorial team (editors, Editorial Board members) are independently peer-reviewed, and the peer review process is managed by the alternative members of the Editorial Board.  All possible measures are undertaken to avoid any potential conflict of interest in the handling of such manuscripts at all the stages.

*Criteria exclusively for research papers

1. Initial Screening: please, see above: < Peer Review Process > 

2. Editorial decisions are based upon the reviewers' feedback. Possible decisions of the Editor-in-Chief or Associate Editors include acceptance, minor/major revisions, rejection, resubmission elsewhere, or review by additional expert. Decisions are communicated to the authors along with the reviewers' recommendations and comments. 

3. If manuscript require major revisions, authors are given a defined deadline to relate to reviewers' comments and make necessary changes. Revised manuscripts are typically reevaluated by the initial reviewers.

4. As soon as at least two consensual peer-reviews become available we usually send them to authors automatically.

5. Final decisions on the fate of submitted manuscripts always rest upon the Editor-in-Chief. 

Our policy is to keep all articles published as final VOR (Version of Record) unaltered and exact. However, if changes in already published VOR articles are necessary, they will be executed after case-by-case analysis by Journal Editors and respective staff of Via Medica and in accordance with the recommendations of the Committee on Publication Ethics (COPE). They will be implemented as a Correction Notice, Expression of Concern, Retraction, or Removal. These will be explained in a post-publication notice, permanently linked to the original work to guarantee full transparency and permanency. If authors find errors in their published articles and there is consensus about that among all co-authors, the corresponding author should formulate a detailed request for changes and submit it using the Support contact e-mail at the Journal’s website.

Correction Notice (CN)

A separate CN will be published if an error to be corrected can impact the interpretation of the article, but the integrity of the article has been preserved. Such CN will provide details of the error and changes made to the VOR article. It will be linked to the article of interest, which will also be corrected. Additionally, a footnote will be added to the article displaying the electronic link to the correction notice.

Retractions

A Retraction Statement will be published in accordance with COPE guidelines in all instances where a major disclosed error undermines or invalidates the presented conclusions or where research misconduct or publication misconduct has occurred (fabricated data, plagiarism, manipulated images, etc.). Issuing a retraction will always be preceded by an investigation by our editorial team and an appropriate Editor. In case of retraction, a statement on this matter will be made available in the online issue of the Journal and will be linked to the retracted article online. Additionally, a ‘retracted’ watermark will be added to the article. If articles are retracted, they are not usually removed from the website. In most cases, the arguments for the retraction are so severe that such manuscripts should not be cited in any other scientific literature.

Expressions of Concern

In cases where serious concerns have been raised about a published article, however, the results of the investigation are not conclusive or have not been completed for an extensive period, an Expression of Concern may be issued and linked to the article. This can be later followed by a Correction Notice or Retraction Statement, which will constitute a permanent part of the published record together with the original article.

Article Removal

A Removal Notice (replacing an online article) is restricted for very rare cases of serious problems that cannot be addressed by a Correction Notice or Retraction Statement (e.g., a defamatory article or an article infringing other legal rights, violating the privacy, etc.).

Addenda

An addendum represents a different type of notification aiming to add information to an article and not contradict it. This may be published if authors request updates to their original publication. Addenda in this Journal will usually be subject to review by the Editors and — if accepted — will be electronically linked to the online article to which they relate.

Via Medica (Publisher) self-archiving policy establishes that authors can archive only accepted manuscripts, including the final PDF version and/or  ‘ahead of print’ in any repository. In details, the author may only post their version provided acknowledgment is given to the original source of publication, and a link is inserted to the published article on Via Medica (Publisher) website. Apart from the link mentioned, the acknowledgment should be provided with the full bibliographic record.

This policy applies to complaints on policies, procedures, and actions of AHP’s editorial staff and, as a rule, is regarded as an opportunity for improvement. Complaints will be dealt with by members of the editorial staff, escalating (if required) to Editor-in-Chief, whose decision is regarded as final. Complaints should be directly emailed to a person indicated as a support contact at the Journal’s contact panel.  All complaints will be acknowledged within three working days, and, if possible, a full response will be made within three weeks. If this is not possible, an interim response will be given within this timeframe. Further responses will be provided until the issue is resolved.

If authors are convinced that the article they submitted was rejected wrongly, they should send a rebuttal letter via AHP’s support contact rather than submitting a revised article at this stage. If the editors agree to such an appeal, authors may be asked to submit a revised version of the article in question, which will enter again into AHP’s review process. The rebuttal letter should be detailed and include responses to comments from external reviewers and Journal’s editors. Only one appeal per article will be considered. An invitation for resubmission after appealing is by itself not a guarantee of acceptance.

“Acta Haematologica Polonica” (AHP) will accept advertising for services and products that are of value to readers in their professions.

Online advertising or sponsorship should not impede users’ access to editorial content. Journal accepts advertising from competitors.

This publication is intended for doctors and students of medicine. Every effort has been made to provide actual information, especially on medicine dosage. However, it is advisable that doctors make final decisions on their usage. It is not meant to replace a proper medical diagnosis or therapy. Responsibility taken by authors is suitable for this kind of publication and is not tantamount to responsibility for an individual medical advice. The Publisher has made every effort concerning the reliability of the publication and the included information on the assortment, medicines, and prices. Yet the only legal information valid in the Republic of Poland are legal acts and in terms of trade–price offers of drugstores. As far as the information on medicines is concerned, the only lawful information is an updated characteristic of a medicinal substance and its producer’s leaflet. The authors, consultants, and publishers of this publication do not take any responsibility for possible mistakes or harms resulting from the information usage. Any cases of legal claims connected with medicines and chemical substances being under clinical examination are not going to be taken into consideration.
