Annals of Pediatric Cardiology (APC) a peer-reviewed international journal is being published under the auspices of the Pediatric Cardiac Society of India (PCSI).

The journal’s full text is online at www.annalspc.com . With the aim of faster and better dissemination of knowledge, we will be publishing articles ‘Ahead of Print’ immediately on acceptance. In addition, the journal would allow free access (Open Access) to its contents, which is likely to attract more readers and citations to articles published in APC.

Manuscripts must be prepared in accordance with "Uniform requirements for Manuscripts submitted to Biomedical Journals" developed by the International Committee of Medical Journal Editors (October 2006). The uniform requirements and specific requirement of APC are summarized below. Before sending a manuscript contributors are requested to check for the latest instructions available. Instructions are also available from the website of the journal  (http://www.annalspc.com) and from the manuscript submission site (http://www.journalonweb.com/APC).

 

Scope of the journal

The journal will cover clinical and technical studies related to congenital cardiac problems in newborns, infants, children, adolescents and adults. It will also address issues related to some of the acquired heart diseases in children and adolescents such as rheumatic heart disease, pericarditis, aortoarteritis, cardiac tumors, pulmonary hypertension etc. It will publish material related to fetal cardiac malformations including fetal interventions. Articles dealing with physiology, pharmacology, pathology, cardiology, imaging, cardiac surgery, cardiac anesthesia, critical care, nursing and more basic specialities such as genetics and molecular biology will be published. The Journal would publish peer-reviewed original research papers, brief communications, case reports, images, reviews, state-of-the-art articles, point-counterpoint and various interventional and surgical techniques (How I do it).

The Editorial process

The manuscripts will be reviewed for possible publication with the understanding that they are being submitted to one journal at a time and have not been published, simultaneously submitted or already accepted for publication elsewhere.

All manuscripts received will be duly acknowledged. The Editors will review all submitted manuscripts initially. Manuscripts with insufficient originality, serious scientific and technical flaws, or lack of a significant message will be rejected. Manuscripts will be sent to two or more expert reviewers without revealing the identity of the contributors to the reviewers. Each manuscript will also be assigned to a member of the editorial team, who based on the comments from the reviewers will take a final decision on the manuscript. The contributors will be informed about the reviewers' comments and acceptance/rejection of manuscript.

Articles accepted would be copy edited for grammar, punctuation, print style, and format. Page proofs will be sent to the corresponding author, which has to be returned within three days.
 

Clinical Trial Registry

All clinical trials from India must be registered with “clinical trials registry – India” . The trials conducted outside India may be registered with any other clinical trial registry. The Indian council of medical research has recommended making it mandatory to have registration number for all clinical trials submitted for publication from January 2009.

Authorship criteria

Authorship credit should be based only on substantial contributions

1. Conception and design or acquisition of data or analysis and interpretation of data;
2. Drafting the article or revising it critically for important intellectual content;
3. Final approval of the version to be published.

Conditions 1, 2, and 3 must be met. Participation solely in the acquisition of funding or the collection of data does not justify authorship. General supervision of the research group is not sufficient for authorship. Each contributor should have participated sufficiently in the work to take public responsibility for appropriate portions of the content. The order of naming the contributors should be based on the relative contribution of the contributor towards the study and writing the manuscript. Once submitted the order cannot be changed without written consent of all the contributors.

Conflicts of Interest

All authors of submitting articles to the journal must disclose any conflict of interest they may have with an institution or product that is mentioned in the manuscript and/or is important to the outcome of the study presented. Authors should also disclose conflict of interest with products that compete with those mentioned in their manuscript. The Editor will discuss with the authors on an individual basis the method by which any conflicts of interest will be communicated to the readers.

Copies of any permission(s)

To reproduce published material, and to use illustrations or report information about identifiable people a copy of the permission obtained must accompany the manuscript. Copies of any and all published articles or other manuscripts in preparation or submitted elsewhere that are related to the manuscript must also accompany the manuscript. The manuscript should be sent to

When you submit an article, the following items must be included. Manuscripts that do not adhere to the following instructions will be returned to the corresponding author for technical revision before undergoing peer review.

1. Unblinded Title Page/First Page File/covering letter: All information which can reveal your identity should be here. Use text/rtf/doc files. Do not zip the files. Provide the highest degree of each author. The covering letter must include
    
   1. A full statement to the editor about all submissions and previous reports that might be regarded as redundant publication of the same or very similar work. Any such work should be referred to specifically, and referenced in the new paper. Copies of such material should be included with the submitted paper, to help the editor decide how to handle the matter.
   2. A statement of financial or other relationships that might lead to a conflict of interest, if that information is not included in the manuscript itself or in an authors' form
   3. A statement that the manuscript has been read and approved by all the authors, that the requirements for authorship as stated earlier in this document have been met, and that each author believes that the manuscript represents honest work, if that information is not provided in another form (see below); and

Preparation of Manuscript

The text of original articles should be divided into sections with the headings: Abstract, Key-words, Introduction, Material and Methods, Results, Discussion, References, Tables and Figure legends. For a Case Report include Abstract, Key words, Introduction, Case History, Discussion, References, Tables and Legends in that order. For Images, include Case History, Discussion, References and Legends. Do not use subheadings in these sections. Use double spacing throughout. Number pages consecutively, beginning with the title page. The language should be American English.

Title Page

The title page should carry

1. Type of manuscript (e.g. Original article, Case Report)
2. The title of the article, which should be concise, but informative;
3. Running title or short title not more than 50 characters;
4. The name by which each contributor is known (Last name, First name and initials of middle name), with his or her highest academic degree(s) and institutional affiliation;
5. The name of the department(s) and institution(s) to which the work should be attributed;

8. Source(s) of support in the form of grants, equipment, drugs, or all of these;
9. Acknowledgement, if any; one or more statements should specify
   1. contributions that need acknowledging but do not justify authorship, such as general support by a departmental chair;
   2. acknowledgments of technical help; and
   3. acknowledgments of financial and material support, which should specify the nature of the support. This should be included in the title page of the manuscript and not in the main article file.
10. If the manuscript was presented as part at a meeting, the organization, place, and exact date on which it was read.
11. Registration number of clinical trials.

Abstract Page
The second page should carry the full title of the manuscript and an abstract (of no more than 150 words for brief reports and 250 words for original articles and other article types). The abstract should be structured for original articles. State the context (background), aims, settings and design, material and methods, statistical analysis used, results and conclusions. Below the abstract should provide 3 to 8 keywords. The abstract should not be structured for a brief report, review article, symposia and research methodology. Do not include references in abstract.

Introduction
State the purpose and summarize the rationale for the study or observation.

Methods
The Methods section should only include information that was available at the time the study was planned or protocol written; all information obtained during the conduct of the study belongs to the results section.

Selection and Description of Participants: Describe your selection of the observational or experimental participants (patients or laboratory animals, including controls) clearly, including eligibility and exclusion criteria and a description of the source population. Because the relevance of such variables as age and sex to the object of research is not always clear, authors should explain their use when they are included in a study report; for example, authors should explain why only subjects of certain ages were included or why women were excluded. The guiding principle should be clarity about how and why a study was done in a particular way. When authors use variables such as race or ethnicity, they should define how they measured the variables and justify their relevance.

Technical information: Identify the methods, apparatus (give the manufacturer's name and address in parentheses), and procedures in sufficient detail to allow other workers to reproduce the results. Give references to established methods, including statistical methods (see below); provide references and brief descriptions for methods that have been published but are not well known; describe new or substantially modified methods, give reasons for using them, and evaluate their limitations. Identify precisely all drugs and chemicals used, including generic name(s), dose(s), and route(s) of administration.

Reports of randomized clinical trials should present information on all major study elements, including the protocol, assignment of interventions (methods of randomization, concealment of allocation to treatment groups), and the method of masking (blinding), based on the CONSORT Statement (http://www.consort-statement.org).
 

Note: Authors submitting review article should include a section describing the methods used for locating, selecting, extracting, and synthesizing data. These methods should also be summarized in the abstract

Ethics
When reporting studies on human, indicate whether the procedures followed were in accordance with the ethical standards of the responsible committee on human experimentation (institutional or regional) and with the Helsinki Declaration of 1975, as revised in 2000 (available at http://www.wma.net/e/policy/17-c_e.html ). Do not use patients’ names, initials, or hospital numbers, especially in illustrative material. When reporting experiments on animals, indicate whether the institution’s or a national research council’s guide for, or any national law on the care and use of laboratory animals was followed.

Evidence for approval by a local Ethics Committee (for both human as well as animal studies) must be supplied by the authors on demand. Animal experimental procedures should be as humane as possible and the details of anesthetics and analgesics used should be clearly stated. The ethical standards of experiments must be in accordance with the guidelines provided by the CPCSEA (animal) and ICMR (human). The journal will not consider any paper which is ethically unacceptable. A statement on ethics committee permission and ethical practices must be included in all research articles under the ‘Materials and Methods’ section.

Statistics
Whenever possible quantify findings and present them with appropriate indicators of measurement error or uncertainty (such as confidence intervals). Report losses to observation (such as dropouts from a clinical trial). When data are summarized in the Results section, specify the statistical methods used to analyze them. Avoid non-technical uses of technical terms in statistics, such as 'random' (which implies a randomizing device), 'normal', 'significant', 'correlations', and 'sample'. Define statistical terms, abbreviations, and most symbols. Specify the computer software used. Use upper italics (P 0.048). For all P values include the exact value and not less than 0.05 or 0.001.

Results
Present your results in a logical sequence in the text, tables, and illustrations, giving the main or most important findings first. Do not repeat in the text all the data in the tables or illustrations; emphasize or summarize only important observations. Extra or supplementary materials and technical detail can be placed in an appendix where it will be accessible but will not interrupt the flow of the text; alternatively, it can be published only in the electronic version of the journal.
When data are summarized in the Results section, give numeric results not only as derivatives (for example, percentages) but also as the absolute numbers from which the derivatives were calculated, and specify the statistical methods used to analyze them. Restrict tables and figures to those needed to explain the argument of the paper and to assess its support. Use graphs as an alternative to tables with many entries; do not duplicate data in graphs and tables. "Where scientifically appropriate, analyses of the data by variables such as age and sex should be included.

Discussion
Include summary of key findings (primary outcome measures, secondary outcome measures, results as they relate to a prior hypothesis); Strengths and limitations of the study (study question, study design, data collection, analysis and interpretation); Interpretation and implications in the context of the totality of evidence (is there a systematic review to refer to, if not, could one be reasonably done here and now?, what this study adds to the available evidence, effects on patient care and health policy, possible mechanisms); Controversies raised by this study; and Future research directions (for this particular research collaboration, underlying mechanisms, clinical research).

Do not repeat in detail data or other material given in the Introduction or the Results section. In particular, contributors should avoid making statements on economic benefits and costs unless their manuscript includes economic data and analyses. Avoid claiming priority and alluding to work that has not been completed. State new hypotheses when warranted, but clearly label them as such.

References
References should be numbered consecutively in the order in which they are first mentioned in the text (not in alphabetic order). Identify references in text, tables, and legends by Arabic numerals in superscript with square bracket after the punctuation marks. References cited only in tables or figure legends should be numbered in accordance with the sequence established by the first identification in the text of the particular table or figure. Use the style of the examples below, which are based on the formats used by the NLM in Index Medicus. The titles of journals should be abbreviated according to the style used in Index Medicus. Use complete name of the journal for non-indexed journals. Avoid using abstracts as references. Information from manuscripts submitted but not accepted should be cited in the text as "unpublished observations" with written permission from the source. Avoid citing a "personal communication" unless it provides essential information not available from a public source, in which case the name of the person and date of communication should be cited in parentheses in the text.

The commonly cited types of references are shown here, for other types of references such as electronic media; newspaper items, etc. please refer to ICMJE Guidelines ( http://www.icmje.org  or http://www.nlm.nih.gov/bsd/uniform_requirements.html).
