Overview

Top Research Topics at The Lancet Gastroenterology & Hepatology?

The foci of the journal are Internal medicine, Gastroenterology, Intensive care medicine, Virology and Surgery. Topics in Internal medicine explored in it were investigated in conjunction with research in Placebo and Oncology. The Oncology study featured in The Lancet Gastroenterology & Hepatology draws connections with the study of Colorectal cancer.

The Lancet Gastroenterology & Hepatology facilitates discussions in 2019-20 coronavirus outbreak and Hepatitis C as part of the larger field of Virology, however, it also tackles fields such as Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Interdisciplinary research on topics like 2019-20 coronavirus outbreak and Coronavirus Infections are the foci of the journal. The work on Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) addressed in The Lancet Gastroenterology & Hepatology expands to the thematically related Pandemic.

Attendees of The Lancet Gastroenterology & Hepatology participated in discussions that delve into both Pandemic and Pneumonia. Disease, which encompasses Fatty liver and Inflammatory bowel disease, is the main subject of it. The journal focuses on Randomized controlled trial as well as the interrelated topic of Clinical trial.

Publication chance based on affiliation

The publication chance index shows the ratio of articles published by the best research institutions in the journal edition to all articles published within that journal. The best research institutions were selected based on the largest number of articles published during all editions of the journal.

The chart below presents the percentage ratio of articles from top institutions (based on their ranking of total papers).Top affiliations were grouped by their rank into the following tiers: top 1-10, top 11-20, top 21-50, and top 51+. Only articles with a recognized affiliation are considered.

During the most recent 2021 edition, 15.28% of publications had an unrecognized affiliation. Out of the publications with recognized affiliations, 26.78% were posted by at least one author from the top 10 institutions publishing in the journal. Another 14.21% included authors affiliated with research institutions from the top 11-20 affiliations. Institutions from the 21-50 range included 16.39% of all publications and 42.62% were from other institutions.

Returning Authors Index

A very common phenomenon observed among researchers publishing scientific articles is the intentional selection of journals they have already attended in the past. In particular, it is worth analyzing the case when the authors participate in the same journal from year to year.

The Returning Authors Index presented below illustrates the ratio of authors who participated in both a given as well as the previous edition of the journal in relation to all participants in a given year.

Returning Institution Index

The graph below shows the Returning Institution Index, illustrating the ratio of institutions that participated in both a given and the previous edition of the conference in relation to all affiliations present in a given year.

The experience to innovation index

Our experience to innovation index was created to show a cross-section of the experience level of authors publishing in a journal. The index includes the authors publishing at the last edition of a journal, grouped by total number of publications throughout their academic career (P) and the total number of citations of these publications ever received (C).

The group intervals were selected empirically to best show the diversity of the authors' experiences, their labels were selected as a convenience, not as judgment. The authors were divided into the following groups:

  • Novice - P < 5 or C < 25 (the number of publications less than 5 or the number of citations less than 25),
  • Competent - P < 10 or C < 100 (the number of publications less than 10 or the number of citations less than 100),
  • Experienced - P < 25 or C < 625 (the number of publications less than 25 or the number of citations less than 625),
  • Master - P < 50 or C < 2500 (the number of publications less than 50 or the number of citations less than 2500),
  • Star - P ≥ 50 and C ≥ 2500 (both the number of publications greater than 50 and the number of citations greater than 2500).

The chart below illustrates experience levels of first authors in cases of publications with multiple authors.

Career Opportunities and Licensing Requirements for Gastroenterology Researchers

A career in gastroenterology research offers an array of opportunities to contribute in areas ranging from clinical trials to new treatment method developments. Researchers often work closely with physicians and other healthcare professionals to explore, develop and implement cutting-edge treatments for gastrointestinal diseases, making a significant impact in the field of medicine. However, it's worth noting that depending on your location, specific licensing requirements might apply. For instance, research staff who are also practicing nurses, like some who work in clinical trials, must meet specific licensing requirements for their state. If you're planning a research career in New Jersey, you may need a professional nurse license. More details about the New Jersey state requirements can be found on our new jersey nursing license requirements page, which also provides insights about the associated costs of acquiring the license. Remember, understanding the licensing requirements and costs of your intended practice area is a crucial first step in planning your career in gastroenterology research.
