"Journal of Clinical and Diagnostic Research is at present a well-known Indian originated scientific journal which started with a humble beginning. I have been associated with this journal since many years. I appreciate the Editor, Dr. Hemant Jain, for his constant effort in bringing up this journal to the present status right from the scratch. The journal is multidisciplinary. It encourages in publishing the scientific articles from postgraduates and also the beginners who start their career. At the same time the journal also caters for the high quality articles from specialty and super-specialty researchers. Hence it provides a platform for the scientist and researchers to publish. The other aspect of it is, the readers get the information regarding the most recent developments in science which can be used for teaching, research, treating patients and to some extent take preventive measures against certain diseases. The journal is contributing immensely to the society at national and international level."

" Journal of Clinical and Diagnostic Research (JCDR) is a multi-specialty medical and dental journal publishing high quality research articles in almost all branches of medicine. The quality of printing of figures and tables is excellent and comparable to any International journal. An added advantage is nominal publication charges and monthly issue of the journal and more chances of an article being accepted for publication. Moreover being a multi-specialty journal an article concerning a particular specialty has a wider reach of readers of other related specialties also. As an author and reviewer for several years I find this Journal most suitable and highly recommend this Journal."

Dr. Mamta Gupta,
"It gives me great pleasure to be associated with JCDR, since last 2-3 years. Since then I have authored, co-authored and reviewed about 25 articles in JCDR. I thank JCDR for giving me an opportunity to improve my own skills as an author and a reviewer.
It 's a multispecialty journal, publishing high quality articles. It gives a platform to the authors to publish their research work which can be available for everyone across the globe to read. The best thing about JCDR is that the full articles of all medical specialties are available as pdf/html for reading free of cost or without institutional subscription, which is not there for other journals. For those who have problem in writing manuscript or do statistical work, JCDR comes for their rescue.
The journal has a monthly publication and the articles are published quite fast. In time compared to other journals. The on-line first publication is also a great advantage and facility to review one's own articles before going to print. The response to any query and permission if required, is quite fast; this is quite commendable. I have a very good experience about seeking quick permission for quoting a photograph (Fig.) from a JCDR article for my chapter authored in an E book. I never thought it would be so easy. No hassles.
Reviewing articles is no less a pain staking process and requires in depth perception, knowledge about the topic for review. It requires time and concentration, yet I enjoy doing it. The JCDR website especially for the reviewers is quite user friendly. My suggestions for improving the journal is, more strict review process, so that only high quality articles are published. I find a a good number of articles in Obst. Gynae, hence, a new journal for this specialty titled JCDR-OG can be started. May be a bimonthly or quarterly publication to begin with. Only selected articles should find a place in it.
An yearly reward for the best article authored can also incentivize the authors. Though the process of finding the best article will be not be very easy. I do not know how reviewing process can be improved. If an article is being reviewed by two reviewers, then opinion of one can be communicated to the other or the final opinion of the editor can be communicated to the reviewer if requested for. This will help one’s reviewing skills.
My best wishes to Dr. Hemant Jain and all the editorial staff of JCDR for their untiring efforts to bring out this journal. I strongly recommend medical fraternity to publish their valuable research work in this esteemed journal, JCDR".

"I wish to thank Dr. Hemant Jain, Editor-in-Chief Journal of Clinical and Diagnostic Research (JCDR), for asking me to write up few words.
Writing is the representation of language in a textual medium i e; into the words and sentences on paper. Quality medical manuscript writing in particular, demands not only a high-quality research, but also requires accurate and concise communication of findings and conclusions, with adherence to particular journal guidelines. In medical field whether working in teaching, private, or in corporate institution, everyone wants to excel in his / her own field and get recognised by making manuscripts publication.


Authors are the souls of any journal, and deserve much respect. To publish a journal manuscripts are needed from authors. Authors have a great responsibility for producing facts of their work in terms of number and results truthfully and an individual honesty is expected from authors in this regards. Both ways its true "No authors-No manuscripts-No journals" and "No journals–No manuscripts–No authors". Reviewing a manuscript is also a very responsible and important task of any peer-reviewed journal and to be taken seriously. It needs knowledge on the subject, sincerity, honesty and determination. Although the process of reviewing a manuscript is a time consuming task butit is expected to give one's best remarks within the time frame of the journal.
Salient features of the JCDR: It is a biomedical, multidisciplinary (including all medical and dental specialities), e-journal, with wide scope and extensive author support. At the same time, a free text of manuscript is available in HTML and PDF format. There is fast growing authorship and readership with JCDR as this can be judged by the number of articles published in it i e; in Feb 2007 of its first issue, it contained 5 articles only, and now in its recent volume published in April 2011, it contained 67 manuscripts. This e-journal is fulfilling the commitments and objectives sincerely, (as stated by Editor-in-chief in his preface to first edition) i e; to encourage physicians through the internet, especially from the developing countries who witness a spectrum of disease and acquire a wealth of knowledge to publish their experiences to benefit the medical community in patients care. I also feel that many of us have work of substance, newer ideas, adequate clinical materials but poor in medical writing and hesitation to submit the work and need help. JCDR provides authors help in this regards.
Timely publication of journal: Publication of manuscripts and bringing out the issue in time is one of the positive aspects of JCDR and is possible with strong support team in terms of peer reviewers, proof reading, language check, computer operators, etc. This is one of the great reasons for authors to submit their work with JCDR. Another best part of JCDR is "Online first Publications" facilities available for the authors. This facility not only provides the prompt publications of the manuscripts but at the same time also early availability of the manuscripts for the readers.
Indexation and online availability: Indexation transforms the journal in some sense from its local ownership to the worldwide professional community and to the public.JCDR is indexed with Embase & EMbiology, Google Scholar, Index Copernicus, Chemical Abstracts Service, Journal seek Database, Indian Science Abstracts, to name few of them. Manuscriptspublished in JCDR are available on major search engines ie; google, yahoo, msn.
In the era of fast growing newer technologies, and in computer and internet friendly environment the manuscripts preparation, submission, review, revision, etc and all can be done and checked with a click from all corer of the world, at any time. Of course there is always a scope for improvement in every field and none is perfect. To progress, one needs to identify the areas of one's weakness and to strengthen them.
It is well said that "happy beginning is half done" and it fits perfectly with JCDR. It has grown considerably and I feel it has already grown up from its infancy to adolescence, achieving the status of standard online e-journal form Indian continent since its inception in Feb 2007. This had been made possible due to the efforts and the hard work put in it. The way the JCDR is improving with every new volume, with good quality original manuscripts, makes it a quality journal for readers. I must thank and congratulate Dr Hemant Jain, Editor-in-Chief JCDR and his team for their sincere efforts, dedication, and determination for making JCDR a fast growing journal.
Every one of us: authors, reviewers, editors, and publisher are responsible for enhancing the stature of the journal. I wish for a great success for JCDR."

Dr. Shankar P.R.

"On looking back through my Gmail archives after being requested by the journal to write a short editorial about my experiences of publishing with the Journal of Clinical and Diagnostic Research (JCDR), I came across an e-mail from Dr. Hemant Jain, Editor, in March 2007, which introduced the new electronic journal. The main features of the journal which were outlined in the e-mail were extensive author support, cash rewards, the peer review process, and other salient features of the journal.
Over a span of over four years, we (I and my colleagues) have published around 25 articles in the journal. In this editorial, I plan to briefly discuss my experiences of publishing with JCDR and the strengths of the journal and to finally address the areas for improvement.
My experiences of publishing with JCDR: Overall, my experiences of publishing withJCDR have been positive. The best point about the journal is that it responds to queries from the author. This may seem to be simple and not too much to ask for, but unfortunately, many journals in the subcontinent and from many developing countries do not respond or they respond with a long delay to the queries from the authors 1. The reasons could be many, including lack of optimal secretarial and other support. Another problem with many journals is the slowness of the review process. Editorial processing and peer review can take anywhere between a year to two years with some journals. Also, some journals do not keep the contributors informed about the progress of the review process. Due to the long review process, the articles can lose their relevance and topicality. A major benefit with JCDR is the timeliness and promptness of its response. In Dr Jain's e-mail which was sent to me in 2007, before the introduction of the Pre-publishing system, he had stated that he had received my submission and that he would get back to me within seven days and he did!
Most of the manuscripts are published within 3 to 4 months of their submission if they are found to be suitable after the review process. JCDR is published bimonthly and the accepted articles were usually published in the next issue. Recently, due to the increased volume of the submissions, the review process has become slower and it ?? Section can take from 4 to 6 months for the articles to be reviewed. The journal has an extensive author support system and it has recently introduced a paid expedited review process. The journal also mentions the average time for processing the manuscript under different submission systems - regular submission and expedited review.
Strengths of the journal: The journal has an online first facility in which the accepted manuscripts may be published on the website before being included in a regular issue of the journal. This cuts down the time between their acceptance and the publication. The journal is indexed in many databases, though not in PubMed. The editorial board should now take steps to index the journal in PubMed. The journal has a system of notifying readers through e-mail when a new issue is released. Also, the articles are available in both the HTML and the PDF formats. I especially like the new and colorful page format of the journal. Also, the access statistics of the articles are available. The prepublication and the manuscript tracking system are also helpful for the authors.
Areas for improvement: In certain cases, I felt that the peer review process of the manuscripts was not up to international standards and that it should be strengthened. Also, the number of manuscripts in an issue is high and it may be difficult for readers to go through all of them. The journal can consider tightening of the peer review process and increasing the quality standards for the acceptance of the manuscripts. I faced occasional problems with the online manuscript submission (Pre-publishing) system, which have to be addressed.
Overall, the publishing process with JCDR has been smooth, quick and relatively hassle free and I can recommend other authors to consider the journal as an outlet for their work."

Abstract

Background and objectives:
Obesity is a common health problem all over the world and it is closely associated with many diseases that cause disturbances in the lung function. The objective of the present study was to assess the impact of increased body mass index (BMI) on the expiratory reserve volume (ERV).

Materials and Methods:
This study was conducted on 80 subjects of ages ranging from 25-40 years, of both the sexes. Of these, 40 were non-obese (BMI < 25 kg/m²) and 40 were obese(BMI > 30kg/m²). This study was carried out in the Department of T.B and Chest Diseases at the Infections Disease Hospital, Guntur, by using a computerized spirometer (Spiro-232, PK Morgan limited).

Results:
On the comparison of the results, the subjects with a BMI of more than 30 kg/m² showed a decrease in ERV by 48.13%, than the normal subjects. Conclusion: An increased BMI resulted in decreased expiratory reserve volume and the changes were more marked in males than in the females.

Obesity is a chronic disease which is prevalent in both the developed and the developing countries, affecting children as well as adults. As the standards of living are continuing to rise, weight gain and obesity are posing a growing threat to health in countries all over the world (1). More than 300 million people are affected by obesity world wide (2), and its prevalence is increasing at a significant pace. These obese individuals are at an increased risk of morbidity and mortality from conditions such as diabetes, heart disease, hypertension, sleep-disordered breathing and some forms of cancer (3).

Obesity causes various effects on respiratory function in the form of alteration in the respiratory mechanics, decreased respiratory muscle strength, decrease in the pulmonary gas exchange, a lower control of breathing and a limitation in the pulmonary function tests (4). These changes in the lung function tests are due to the accumulation of adipose tissue in the abdominal cavity and also over the chest wall, thus causing a decreased displacement of the diaphragm, decreased lung and chest wall compliance, increase in the elastic recoil and a decrease in the lung volumes.

Body fat deposition may also have a distinct impact on the ventilatory function and it is often described in two distinct patterns- a central pattern which is also called as the upper body pattern, which is usually seen in obese men and a peripheral or lower body pattern which is seen in obese women. Importantly, the central pattern of obesity is the more significant one (5).

The most frequently reported obesity related abnormalities are reductions in the lung volumes and in the expiratory flow rate (6). Some studies have shown a clear correlation between weight loss and improvement in the lung function tests (7). (8). A significant improvement in the expiratory reserve volume (ERV) to up to 54%, has been observed after weight loss (7).

The objectives of the present study were 1) To compare the lung function tests in the local population of obese and non-obese adults and 2) To compare the severity of the impairment in the lung function between males and females.

Material and Methods

This study was conducted in the Department of T.B and Chest Diseases at the Infectious Disease Hospital, Guntur, Andhra Pradesh, after getting an approval from the institutional ethics committee (IEC), on 40 adult obese subjects (20 males and 20 females). Forty non-obese subjects (20 males and 20 females) were taken as the controls. All the subjects who were considered for the study were aged between 25- 40 years and were nonsmokers, non-alcoholics and non-diabetics. Moreover, they were not suffering from any cardiovascular or respiratory diseases. Thus, all the subjects who were chosen for the study were obese but were otherwise healthy. The BMI was calculated by using the formula - BMI = Weight/ Height2, where the weight is in kilograms and height is in meters. The subjects with a BMI of more than 30kg/m² were included in our study under the obese group and subjects with a BMI of less than 25kg/m² were included inthe non-obese group. All the subjects were informed about the experimental protocol in their local language and their consent was obtained. Physical parameters such as height, weight, BMI, pulse, blood pressure and respiratory rate were recorded. The instrument which was used for the study was a computerized spirometer (spiro-232. PK Morgan limited). The expiratory reserve volume (ERV) was recorded in the sitting position by applying a nose clip.

Results

The data which was obtained from the 40 obese and 40 nonobese subjects was statistically analyzed. Initially, the mean and standard deviations were calculated. The unpaired Students t-test was used to test the statistical significance of the difference between the ERV of the non-obese and the obese groups. When the results were compared, it was found that the mean ERV in the obese group was lower than that in the non-obese group (p <0.001). The mean ERV was decreased by 48.13% in the obese group as compared to that in the non-obese group (Table/Fig 1).The mean ERV in the obese males (n=20) was decreased by 54.17% as compared to that in the non-obese males (n=20), with a t value of 11.01 and (p < 0.001). The female obese subjects showed a 37.4% decrease in the mean ERV, with a t value of 5.93 (p < 0.01) (Table/Fig 2).

Discussion

The present study showed that there was a significant decrease in the expiratory reserve volume in the obese group, whose BMI was more than 30kg/m². Zerah et al (9) (1993) found that with an increase in the BMI, most of the lung volumes were changed and the analysis of variance (ANOVA) showed highly significant reductions in the functional residual capacity (FRC) and ERV. The above study also confirmed that decreased ERV is the most sensitive lung function test in obesity. The findings of the present study are in consistence with the findings of Zerah et al (1993) and other authors (4).(10) (11)(12)(13). This reduction in ERV can be attributed to a decrease in the mobility of the diaphragm towards the abdomen during inspiration, which is caused by an increased abdominal volume in the obese individuals (4). Apart from the reduced movement of the diaphragm as a cause for decreased ERV, Ladosky et al (2001) suggested that the main consequence of a burden on the chest wall which is caused by increased adipose mass, is the reduction in its compliance, thus making inspiration increasingly difficult and resulting in lower static volumes and flows (14). There is an increased intra-abdominal pressure with an accumulation of fat in the abdominal cavity. This raises the intra abdominal pressure due to the visceral obesity and pushes thediaphragmatic muscle upwards, thus causing a compression of the lung parenchyma, especially at the basal region of the lung. Visceral fat produces the over-stretching of diaphragm, thus leading to an elevation of the diaphragmatic domes, which in turn causes a decreased efficiency of the diaphragmatic muscle (15).

In this study, we found that the decreased ERV was more marked in the obese males than in the obese females. This could be due to a difference in the weight distribution in the obese males and females. Males tend to deposit fat centrally, while in females, the deposition is typically peripheral. Thus, the mechanical effect on the diaphragm in men, impeding the expansion of the lungs during inspiration, could justify their higher impairment of the ventilatory function (16).

There were certain limitations in the present study, as the study was a cross sectional assessment of the lung function at one time point. So, it would be ideal to undertake a longitudinal study over a period of time, to understand the progression of the deformity with an increase in the BMI or the improvement in the lung functions with a decrease in the BMI by using weight reduction measures.

Conclusion

Increased BMI causes a significant decrease in the ERV in obese subjects as compared to that in the non-obese subjects and these changes are more marked in obese males than in the obese females.
