"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: Sella turcica is an important landmark seen during cephalogram tracing and evaluation. Its morphology varies in individuals, gender groups, age groups, and ethnicities.

Aim: This cephalometric study was done on a novel population of Dogra ethnicity residing in Jammu to determine the characteristics of sella and its correlation with the sagittal skeletal structures.

Materials and Methods: This study was a cross-sectional study done on cephalograms and included a total of 87 patients, equally classified as Skeletal Class-I, Class-II, Class-III, respectively. The pre-treatment profile cephalogram of the patient was obtained in a standardised method. Manual tracing of all the cephalograms was done on an acetate paper with a tracing pencil under optimal illumination. Area, size, shape, bridging of the sella were measured using a novel template and tabulated in excel sheet and sent for statistical analysis.

Results: The results showed mean area of sella was highest in skeletal Class-III (32.79±3.28 mm) followed by skeletal Class-I (28.31±1.63 mm) and least in skeletal Class-II subjects (23.27±2.91 mm). Skeletal Class-III had the greatest mean sella length (10.85±0.80 mm), depth (10.54±0.89 mm), Anteroposterior (AP) diameter (13.20±0.83 mm) followed by skeletal Class-I and least in Class-II. Normal sella turcica was prevalent among all the skeletal.

Conclusion: The dimensions of the sella obtained from this study provide an estimate about the morphology and size of sella in Dogra population thus providing knowledge to the local Orthodontist about the varied appearance of sella and helps in distinguishing the physiological and pathological patterns of sella.

Keywords

Bridging of the sella, Cephalogram, Ethnic variations

One of the important anthropometric landmark used in cephalometric tracing and analysis for Orthodontic treatment management is sella turcica (1). A very popular name for it is the “Turkish saddle” and is anatomically situated in the midline depression of the sphenoid bone’s middle cranial fossa (2). On a cephalogram it appears as a excavated cavity resembling a ‘U’ or an inverted omega (O) and hosts a very important glandular structure called the pituitary gland.

Considering sella turcica as the anatomical centre of cranial base, it is an important region during embryonic development. Sella turcica forms an important key in neural crest cell migration to the frontal, palatal and maxillary development. These neural crest cells along with the dental epithelial progenitor cells are involved in the formation and development of sella turcica and teeth. So any embryological malformations of the sella turcica may be associated with growth malformations of maxilla, palate and mandible occasionally involving the brainstem, thymus, thyroid and heart as well as glandular disorders (3),(4).

In Orthodontics, the sella turcica has gained importance as a stable osseous landmark seen on lateral cephalometric radiographs (5) as well as in craniofacial superimposition techniques (6). The sella point (s-point) given by Bjork is an exact centre of sella turcica and is a common Orthodontic marker used for cephalometric tracing and analysis of the maxilla and mandible (7).

Sella turcica has been vastly studied. Multiple research studies have been done on sellar area shape, size, depth (8),(9), relationship of sagittal and vertical growth patterns with sella (10), bridging of sella (11),(12),(13). Monozygotic twins (14) morphologic features of sella turcica in syndromic patients [15-18]. There are quite a number of studies on the various ethnicities which include Norwegians, Iranians, Nigerians, Polish, Saudi and South Indians regarding the different morphology and the size of sella turcica (19),(20),(21),(22),(23). All the studies have revealed that variability in sella morphology exist in different ethnicities, and established norms for specific ethnic groups are lacking. As per literature search, none of the studies on sellar morphology has been reported on the Dogra ethnic group and that is why this study was taken to compare area, size, shape and incidence of bridging of sella in subjects belonging to Dogra ethnic group. The data from this study was then compared with studies done on other ethnic groups in the past.

The Dogras are an Indo-Aryan ethno-linguistic group speaking Dogri language. They primarily inhabit the Jammu region of Jammu and Kashmir, as well as neighbouring regions of Punjab, Himachal Pradesh, and north-eastern Pakistan. Their ancestral homeland is called Duggar. While many Dogra in Jammu and Kashmir practise Hinduism, a sizable minority adhere to islam, christianity, and buddhism (24),(25),(26),(27).

Material and Methods

This was a cross-sectional descriptive study. The sample included subjects of Dogri origin derived from patients reporting for Orthodontic treatment to Department of Orthodontics, Indira Gandhi Government Dental College and Hospital, Jammu who were asked to provide details about their ethnic background. This study was completed over a period of one year and seven months from 30-04-2021 to 01-12-2022. All procedures performed in this study were in accordance with the ethical standards of the institutional research committee of Indira Gandhi Government Dental College and Hospital, Jammu. (No:IEC/IGGDC/45).

Inclusion criteria: 1) The age range of 12 to 27 years; 2) No facial or spinal abnormalities; 3) Radiographs with the clearest reproduction of the sella turcica area; 4) Both parents born in Jammu (Dogri speaking); 5) Healthy patients without any history of systemic diseases.

Exclusion criteria: 1) Signs of systemic illness (diabetes, metabolic disorder); 2) Undergoing any medical treatment that could interfere like patient on psychotic drugs; 3) Pregnancy; 4) Lateral Cephalograms without sharpness and contrast; 5) Patients suffering from disorders of bone, nutritional deficiencies and endocrinal disturbances; 6) Any history of Orthodontic treatment/cleft repairs.

Keeping the power of study as 90% with alpha error of 5%, the total sample size was calculated to be 87. The total sample size was divided into three groups depending upon the skeletal classification with 29 subjects in each group. Group-I consisted of subjects with Class-I skeletal base, Group-II consisted of subjects with Class-II skeletal base, Group-III consisted of subjects with Class-III skeletal base.

Lateral cephalograms were divided into different classes based on A point, Nasion, B point (ANB) angle value WITS appraisal, YEN angle, Beta angle as depicted in (Table/Fig 1) (28),(29),(30).

Pre-treatment lateral cephalogram of all the patients who were to undergo Orthodontic treatment were obtained in a standardised position with teeth in centric occlusion and Frankfort’s plane parallel to the floor. All the lateral cephalograms were taken by the same trained operator using a cephalostat machine at 66 kV, 0.5 mA, and 18.7 s exposure time using X-ray films on 100% scale. Manual tracing of all the cephalograms was done on an acetate paper with a tracing pencil under optimal illumination.

Tracing of lateral cephalogram: Outline of the sella turcica on each lateral cephalometric radiograph was traced using lead pencil and acetate tracing paper, 0.003? thick under sufficient illumination. Single investigator performed the measurements and assessed the shape and bridging of the sella. To assess intraoperator reliability, five lateral cephalograms were evaluated and re- evaluated after three weeks by the same investigator. The Intra-class Correlation Coefficient (ICC) showed values ranging from 0.61 and 0.71 between the two sets of measurements showing good agreement.

The following measurements of the sella turcica were made on the tracing sheet:

Area of the sella: The area was measured using a transparent novel template simulating graph paper measurements which was designed for measuring the area of sella having measuring squares of 3 mm, 5 mm, 7 mm, 9 mm to superimpose the traced sella directly on the measuring squares for ease of the area measurement, the measurements were made to the nearest of 0.1 mm (Table/Fig 2),(Table/Fig 3).

Size of the sella: the size of the sella was measured using the landmarks by Silverman and Kisling (9),(10) who used the Tuberculum Sella (TS), The Dorsum Sellae (DS), Base of the Pituitary Fossa (BPF) (Table/Fig 4).

Length of the sella turcica- Distance from TS to tip of DS

Depth of the sella turcica- Perpendicular from line above to the deepest point on the floor.

AP diameter of sella turcica- A line drawn from TS to the furthest point on the posterior inner wall of the fossa.

Shape of the sella (Table/Fig 5),(Table/Fig 6),(Table/Fig 7),(Table/Fig 8),(Table/Fig 9),(Table/Fig 10),(Table/Fig 11): The shape of the sella was classified according to Axelsson S et al., (5) Classification as: 1) Normal; 2) Oblique anterior wall; 3) Double contour of floor; 4) Irregular dorsum sella; 5) Pyramidal shape; 6) Bridging of sella.

The bridging of the sella: Bridging of sella was classified according to Becktor et al., into two groups (31): Bridge is present: 1) Type A: Ribbon-Like fusion (Table/Fig 10); 2) Type B: Extension of the anterior or posterior clinoid process (Table/Fig 11).

Incomplete Bridge- A partial calcification of interclinoid ligament is defined as incomplete bridge.

Statistical Analysis

All the lateral cephalograms were traced and values were tabulated in Excel sheet and sent for statistical analysis using SPSS 24. Mean, standard deviation, percentage wise, data was analysed. Various statistical tests done were: One-way ANOVA, Karl Pearson’s correlation coefficient method. The ICC was done to determine the examiner reproducibility (0.8- 0.9- excellent reliability).

Results

(Table/Fig 12) shows the mean age distribution skeletal Class-I, Skeletal-II and Skeletal-III. The overall mean age was 24.00±3.94 years.

(Table/Fig 13) shows the mean area of sella turcica in three skeletal groups. The mean area was highest in skeletal Class-III followed by skeletal Class-I and skeletal Class-II which was statistically significant (p=0.0001).

(Table/Fig 14) shows the mean length, depth, AP dimension of sella in skeletal Class-I, II and III. Skeletal Class-III had the greatest mean length, depth, AP diameter followed by skeletal Class-I, and skeletal Class-II.

The percentage wise prevalence of different sella shapes according to Axelsson S et al., is depicted in (Table/Fig 15). The most prevalent shape was normal sella turcica in skeletal Class-I (58.62%) followed by skeletal Class-II (44.83%) and then skeletal Class-III (37.93%). Notching of posterior wall of sella turcica was seen in mostly Class-II cases. While as oblique anterior wall was seen in the Class-III cases. In overall sample, the most prevalent shapes of sella were: Normal sella > Oblique anterior wall, > notching of posterior wall > double contour of floor > pyramidal shape > irregular.

(Table/Fig 16) shows the overall bridging of sella was missing in 58.62% of the subjects and present in 41.38%. Bridging of sella was present in Class-II >Class-III >Class-I.

(Table/Fig 17) shows the cases where the bridging is present and further evaluation for type of bridging whether complete or partial bridging is present. In overall sample, the Bridging of sella was partial in most of the cases. Bridging of sella was seen both complete and partial in Class-II followed by Class-III and least in Class-I cases. Partial bridging (48.28%) was more prevalent in Class-II skeletal base with bridging of sella.

Discussion

This is the first study to have investigated the sellar characteristics of ethnic Dogra population in skeletal Class-I, II, III subjects which included determining the area, size, shape and bridging of sella. The results of the study revealed the overall mean of the sella area in 90 subjects was 28.12±4.74 mm, however the mean area was highest in skeletal Class-III (32.79±3.28 mm) followed by skeletal Class-I (28.31±1.63 mm) and skeletal Class-II (23.27±2.91 mm). The results of this study are in agreement with the three dimensional Cone-beam Computed Tomography (CBCT) study by Luong HM et al., which showed Class-III subjects had larger sellar volume compared to Class-I and Class-II as well as study conducted on the Iranian population by Moslemzadeh SH et al., who reported a greater length of sella in Class-III individuals (32),(33) and well in alignment with other studies which included Saudi population as well as skeletal Class-I, II and III which have shown significant relationship between sella dimensions and skeletal sagittal relations (23),(33),(34).

In a research (23) conducted by Alkofide EA on Saudi subjects with Class-I, II, III skeletal bases, the morphology of the sella turcica appeared to be normal in shape in the majority of subjects (67 per cent), which is in partial agreement with the results of the current Dogra ethnic study where also majority of subjects (47.13%) had normal sella morphology followed by oblique anterior wall (20.69%) which is contrary to the Saudi subjects which reported only 9.4% subjects with oblique wall and further, the present study showed the notching of posterior wall to be 14.94% and double contour of the floor to be 13.79% which is in alignment with the results of the study by Axselsson S et al., (5).

The normal shape of Sella was more prevalent in Class-I (58.62%) followed by Class-II (44.83%) and least in Class-III (37.93). Notching of posterior wall was seen in 34.48 % subjects which was second highest after the normal shape (44.83%) in Class-II skeletal base which is in agreement with the study on sella morphology of subjects in south Indian population which revealed Class-II skeletal base had more notching of posterior wall which was highest in their overall sample equal to 11%, while only 2% notching was seen in Class-I skeletal subjects which is also contrary to present study where notching had second highest prevalence in Class-I (35). In the present study on Dogra ethnicity, oblique anterior wall was more prevalent (41.38%) in the Class-III subjects followed by normal shape (37.93%) while Class-II showed prevalence of normal shape of sella (44.83) followed by notching of posterior wall (34.48%) and in Class-I subjects, the normal shape was highly prevalent. The present study reported very less pyramidal shape (2.30%) of sella which is consistent with the findings of a study done on North Indian population (36).

In his study, Camp JD measured the mean dimensions of the normal sella turcica in 500 healthy (37), adult individuals, without any demographic classification and found mean of 10.6 mm in the AP direction and 8.1 mm in depth which almost coincided with the results of his another study done on direct measurement of anatomic specimens in autopsy study (38), while in the present study on Dogra ethnicity, the dimensions were quite higher in AP dimension (11.99±1.45), depth (9.08±1.25) and mean length (8.96±1.70) but quite close to the dimensions reported by Kantor ML and Norton LA in their cephalometric study on multi racial subjects belonging to African Americans, Hispanics, and others with a mean age of 14.8 years which revealed the sella turcica mean length was 10.9±1.8 mm, while the mean depth was 7.6±1.7 mm (39).

The present study revealed the highest dimension in Class-III skeletal subjects with mean length of 10.85±0.80 mm, depth of 10.54±0.89 mm, AP diameter of 13.20±0.83 mm followed by skeletal Class-I: length (8.97±0.51), depth (8.38± 0.61 mm), AP dimension (12.34±1.0 mm). Skeletal Class-II had the lowest dimensions with length (7.07±0.79), depth (8.33±0.57), AP dimension (10.41±0.75) of sella as compared to Class-I and III. These results are in agreement with the study of Alkofide EA on Saudi subjects who revealed that larger diameter values were present in the skeletal Class-III subjects (23), while smaller diameter sizes were apparent in Class-II subjects as well as results of a study by Chauhan P et al., on south Indian population who found the linear dimensions greater in Class-III followed by Class-I then Class-II (36).

Studies have reported calcification of diaphragma sella which is radiographically called as “bridging” or “roofing” in 12 percent and 11 percent and the structures that seem to be associated with the greatest variation in sella are the anterior and posterior clinoid processes [38,39]. While the percentage of bridging in the present study was 41.38% which was much higher comparatively and the partial type of bridging was more prevalent which was more associated with skeletal Class-II malocclusion similar to the other studies (32),(35).

Limitation(s)

The limitation of the present study was that sella morphology in relation to male and female population was not seen.

Conclusion

This study showed the overall presence of normal sella in majority of the subjects followed by oblique anterior wall and double contour of the floor. Pyramidal shape of sella was least prevalent. Skeletal Class-III subjects had greater dimensions in area, length, depth, and diameter while Class-II skeletal base had the least dimensions. Overall, the bridging of the sella was present in 41.38% of the subjects and was more prevalent in Class-II skeletal base (65.52%), with mostly partial bridging (48.28%). The average dimension of sella in Dogra population were as follows: area was 28.12 mm, length was 8.96 mm, depth was 9.08 mm, and AP dimension was 11.99 mm. More multicentric studies with an increased sample size should be undertaken.
