"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

Introduction: Patients with Cerebrovascular Accidents (CVA) may present with Gastrointestinal (GI) complications, negatively affecting the prognosis. However, the whole spectrum of GI complications in CVA patients is unknown.

Aim: To assess GI complications in CVA patients and their association with risk factors of CVA.

Materials and Methods: The retrospective, facitlity-based, observational study was conducted in Department of Medicine at Gandhi Medical College and associated Hamidia Hospital, Bhopal, Madhya Pradesh, India, from March 2019 to August 2021. Total 100 patients with CVA (age >13 years) were studied based on their medical records and laboratory examinations. Details on socio-demographic variables and clinical history were obtained. Detailed general and systemic examination and vitals were documented. Complete blood picture, liver function test, renal function test, lipid profile and magnetic resonance imaging scan was also performed. A Chi-square t- test was applied to assess the association of GI complications with various variables. A p-value <0.05 was considered statistically significant.

Results: Most CVA patients were males (51%). Mean age of study population was 71.49±11.46 years. A history of hypertension and diabetes mellitus was observed in 60% and 54% of cases. Constipation (43%) was the most common GI complication, followed by dysphagia (25%). No significant association of GI complications with age (p-value=0.261), gender (p-value=0.217), hypertension (p-value=0.540) and diabetes mellitus (p-value=0.257) was observed in CVA patients. However, raised serum bilirubin, serum glutamic-oxaloacetic transaminase, and serum glutamic pyruvic transaminase in 47%, 23%, and 37% cases with CVA was observed.

Conclusion: Gastrointestinal complications are commonly observed in stroke patients irrespective of stroke but are more common in patients with ischemic stroke. Constipation and dysphagia were the most common. Fecal incontinence, abdominal pain, hiccups, and melena may also be seen in patients with CVA.

Keywords

Constipation, Dysphagia, Lipid profile, Stroke

A Cerebrovascular Accident (CVA), also called a stroke or brain attack is a medical emergency characterized by acute compromise of cerebral perfusion resulting in a neurological deficit (1),(2). The CVA may be of three types, i.e., hemorrhagic stroke, ischaemic stroke, and Transient Ischaemic Attack (TIA). About 85% of strokes are ischaemic, whereas 15% are hemorrhagic (1). TIA is, also termed mini-stroke, is characterized by an acute episode of neurological deficit lasting for a short period, typically less than 1 hour. Recently the definition of TIA includes tissue-based cerebral injury rather than time-based cerebral injury (3).

The CVA is one of the leading causes of mortality and disability worldwide. Global stroke factsheet by World Stroke Organization reported 13.7 million new stroke cases each year, and the incidence of stroke increases with advancing age (4). Approximately, 84% of deaths occur in low-middle-income countries due to stroke (5). In India, 1.17 million new stroke cases were reported from different parts of India in 2016, attributing to a cumulative incidence of 105 to 152 per one lakh person per year (6),(7). Mortality due to CVA was reported in 6.94 lakh cases in India (6).

Hypertension is the predominant risk factor associated with ischaemic stroke; other risk factors include diabetes mellitus, obesity, atrial fibrillation, smoking (8). On the other hand, hemorrhagic stroke results from the bursting of cerebral vessels, which damages the brain cells by exerting pressure on them. Intracerebral hemorrhage (ICH) and subarachnoid hemorrhage are hemorrhagic stroke subtypes (9). Hypertension is a significant risk factor for hemorrhagic stroke also. Other risk factors associated with hemorrhagic stroke include cigarette smoking, heavy alcohol consumption, liver disease, antiplatelet therapy, dyslipidemia (9).

CVA affects the neurological system, but it also leads to a wide range of systemic impairments such as a problem with swallowing, movement, speech, urination, defecation, significantly affecting the quality of life (6). Complications involving the gastrointestinal (GI) system are often neglected, and literature on such complications is scarce. It has been reported that approximately 50% of patients with CVA may present with minor GI complications in the form of constipation, alteration in GI motility, and dysphagia to a severe form, i.e., GI bleeding or intestinal obstruction (10),(11).

The underlying mechanisms attributing to GI complications in patients following a CVA are multifactorial and possible via the brain-gut axis's disruption (12). This axis links the central nervous system with the enteric and autonomic nervous system and helps maintain interaction and communication between the brain and GI system. The alterations in the brain-gut axis may be due to peripheral or central factors or may be due to hormones, amines, or autonomic neural dysfunctions (12).

The GI complications are often neglected in stroke patients. Commonly, GI complications have been observed in ischaemic stroke. The whole spectrum of GI complications in CVA patients is unknown. With the above background, the present study was conducted at a tertiary care centre on stroke survivors to assess the spectrum of GI complications.

Material and Methods

The retrospective, facitlity-based, observational study was conducted in Department of Medicine at Gandhi Medical College and associated Hamidia Hospital, Bhopal, Madhya Pradesh, India, from March 2019 to August 2021. Institutional Ethics Committee approval was obtained before starting the study (letter no: 541/2020).

Inclusion criteria: Patients suffering from CVA having age above 13 years were included in the study.

Exclusion criteria: Patients under age group of 13 years, those not giving written informed consent, and those not having CVA were excluded from the study.

A detailed history regarding socio-demographic variables such as age, gender, address, and contact details, were recorded in proforma. History or relevant family history, if any, was noted.

Detailed general and systemic examination, vitals such as heart rate, blood pressure, temperature, respiratory rate, oxygen saturation were documented. Reports of four systems, and any positive abnormal findings were also noted. Details of routine and special investigations, including complete blood picture, liver function test, renal function test, lipid profile, ultrasonography abdomen, and magnetic resonance imaging scan were also recorded.

Statistical Analysis

Data was compiled using MS Excel and analyzed using IBM Statistical Package for the Social Sciences (SPSS) software version 20.0. Categorical data were expressed as frequency and proportions, whereas continuous data were expressed as mean and standard deviation. A Chi-square’s test was applied to assess the association of GI complications with various variables. A p-value <0.05 was considered statistically significant.

Results

The mean age of patients with CVA was 71.49±11.46 years, and the majority (28%) belonged to 71 to 80 years, followed by 61 to 70 years (26%) and more than 80 years (25%) of age, respectively. Male predominance (51%) was observed, with a male: female ratio of 1.04:1. A history of hypertension was observed in 60% of cases, whereas diabetes was observed in 54% of patients with CVA (Table/Fig 1).

Most common GI complication were constipation (43%), dysphagia (25%), fecal incontinence (12%) and abdominal pain (10%). Other lest common GI complications are shown in (Table/Fig 3). There was no significant association between GI complications and various causes of infarct on MRI (p-value >0.05) (Table/Fig 4).

In the present study, majority had lower hemoglobin (<11 gm%), however, serum creatinine, urea levels, serum bilirubin, SGOT and SGPT were raised in CVA patients along with raised triglyceride levels (Table/Fig 2). No significant association was found between the GI complications and risk factors of CVA (Table/Fig 5).

Discussion

Though GI complications are often reported in patients with CVA, these are often neglected. The GI complications in CVA patients may range from mild to severe such as constipation, dysphagia, GI bleeding, or intestinal obstruction (7).

Advanced age is a non modifiable risk factor of ischaemic and hemorrhagic stroke (13). In the present study, the mean age of CVA patients was 71.49±11.46 years. The majority of patients belonged to 71 to 80 years (28%). As most patients, i.e., more than 85% belonged to the elderly age group (> 60 years), age may be a confounding factor associated with GI complications in CVA patients. However, the present study observed no significant association of GI complications with age. The GI complications were higher in the elderly age group, including constipation, dyspepsia, due to age-related decline in gastric motility (14). The present study findings are supported by the results of Minhas SV et al., in which age of 75 years or older was identified as an independent risk factor for CVA development (15). Similarly, the median age of CVA patients in a study by Tillman H et al. was 65 years (IQR: 55 to 74 years) (16). However, Ji R et al. reported the median age of CVA patients with GI complications as 66 years (IQR: 56-74) (17).

GI complications were observed in almost equal proportions of males and females (51% males and 49% females). Johnson CO et al., reported a higher prevalence of CVA in females than males (41.1 vs. 39 million respectively) (6). Tillman H et al., observed CVA in 45% of women and 55% males (16). Thus, present study reported CVA and associated GI complications in almost equal proportions of males and females with no significant difference in the spectrum of GI complications between males and females.

The majority of previous studies have been done on the Western population. Only a few studies highlighted the GI complications [6,16] and their associated factors in patients with CVA in the Indian scenario. Present study provide further evidences on the GI complications and their association with the classical risk factors of CVA.

Co-morbid condition, particularly hypertension, has been linked with both ischaemic and hemorrhagic stroke. Of 100 CVA patients with GI complications, 60% had associated hypertension, and 54% had diabetes. Hypertension is implicated in the pathogenesis of stroke, irrespective of the type of stroke. Ischaemic stroke or CVA infarct are commonly attributed to underlying uncontrolled hypertension, which increases the risk via lipohyalinosis and arteriolosclerosis (18). The most common etiological mechanism in hemorrhagic stroke is also uncontrolled hypertension (19). Nogueira RG et al., documented hypertension as a significant risk factor of stroke; other factors associated with CVA are diabetes and obesity (8). Ji R et al., documented history of hypertension, hepatic cirrhosis, and peptic ulcer is an important predictor of CVA (17).

MRI was done in all the cases of CVA in the current study to observe the site and type of lesion in CVA. Ischaemic infarct at various sites were the predominant findings in CVA patients, whereas hemorrhagic stroke in the form of occipital microbleed was observed in 1% of cases. Middle Cerebral Artery (MCA) Infarct (46%) and capsulogangliomic region infarct (24%) were the most common findings on MRI. The present study results were concordant to Pandian JD et al., in which ischaemic strokes were the most common etiology in patients reporting cerebrovascular (20). Liu X et al., and Kabi S et al., also observed findings similar to the present study; they documented ischaemic stroke to be more common than hemorrhagic stroke (21),(22). Overall, GI complications have been reported in approximately 50% of the patients with ischaemic stroke (23).

Gastrointestinal complications can be observed in approximately half of the patients with ischaemic stroke (10). A wide spectrum of GI complications has been reported in patients with CVA. In the present study, constipation was the most common gastrointestinal complication observed in 43% of cases with CVA, followed by dysphagia (25%). The study documented fecal incontinence, abdominal pain, hiccups, and melena in a few cases. Though previous studies have not highlighted the entire spectrum of GI complications, various complications have been associated with CVA. Different underlying mechanisms have been implicated in developing gastrointestinal complications in patients following cerebrovascular accidents. Disruption of the brain-gut axis has been observed as the most predominant factor linked with GI complications in CVA patients (8),(12). This axis plays a vital role in interaction and communication between the brain and gastrointestinal system, alteration of which in CVA could be due to peripheral or central factors or to hormones, amines, or autonomic neuralgia dysfunctions (24). The present study findings were supported by Krogh K et al. findings, in which constipation was one of the common complications observed in stroke patients (24). Schaller BJ et al., reported dysphagia, GI dysmotility, and GI hemorrhage as the predominant GI complications in patients with stroke (11). The present study findings were supported by the results of Camara-Lemarroy CR et al., the authors reported GI complications to be common in patients with an acute ischaemic stroke, which is associated with adverse outcomes in such patients in the form of disability, poor neurological function, and even death (23). Li J et al., observed constipation in 48% of patients with stroke, with constipation higher in hemorrhagic stroke compared to ischaemic stroke (25). Fu J et al., observed the risk factors associated with GI bleeding in stroke cases with the prevalence of GI bleeding in 8.5% cases (26).

In the present study, baseline investigations were done in all the cases with CVA. These investigations included complete blood count, LFT, RFT, and lipid profile. Among renal function tests, serum creatinine and urea levels were raised in 8% and 7% cases, respectively. However, triglycerides and LDL were studied in present study population, which were raised in 69% and 3% cases of CVA, respectively. Dyslipidemia is one of the common findings observed in stroke, characterized by increased cholesterol levels that impair the function of the endothelium of blood vessels by producing superoxide and oxygen-free radicals. These changes ultimately increase atherosclerosis in these patients (27). The findings of the present study are supported by the results of Onwuegbuzie GA et al., in which raised LDL was observed in 13%, and triglyceride levels were increased in 43% of patients with stroke (28).

Liver function tests may depict the underlying GI complications in patients with stroke. The present study reported raised serum bilirubin, SGOT, and SGPT in 47%, 23%, and 37% cases with CVA. Muscari A et al., reported significant liver abnormalities during the acute phase of ischaemic stroke. Amongst various liver enzymes, SGOT has been directly linked with ischaemic cerebral lesions and is associated with inflammation (29). The index study study findings are supported by Luo Y et al., who reported direct bilirubin to be significantly associated with the severity of stroke (30).

Small sample size and retrospective nature are the main limitations of the present study. There is a need of a large randomized clinical trials to provide more strength to present study findings.

Conclusion

Gastrointestinal complications are commonly observed in stroke patients irrespective of stroke but are more common in patients with ischaemic stroke. A wide spectrum of gastrointestinal complications could be observed in patients with CVA, including constipation, dysphagia, fecal incontinence, abdominal pain, hiccups, and melena. All these complications increase morbidity as well as mortality in patients with CVA. These complications should be emphasized to ensure early diagnosis and management.
