Insights

This study analyzed global research on COVID-19 and digestive diseases. Liver transplantation and inflammatory bowel disease emerged as the most significant research areas.

Area of Science:

  • Bibliometrics and scientometrics
  • Gastroenterology and hepatology
  • Infectious disease epidemiology

Background:

  • The global spread of coronavirus disease 2019 (COVID-19) has prompted extensive research.
  • Gastrointestinal symptoms are recognized manifestations in COVID-19 patients.
  • This study investigates global research trends at the intersection of COVID-19 and digestive diseases.

Approach:

  • A comprehensive bibliometric analysis was performed on papers identified from PubMed and Web of Science Core Collection up to September 3, 2021.
  • Bibliometric visualization was conducted using VOSviewer and CiteSpace software.
  • The analysis included original articles and reviews, examining publication output, country contributions, journal distribution, and keyword trends.

Key Points:

  • The USA led contributions with 288 articles, followed by China (215) and Italy (160).
  • The World Journal of Gastroenterology published the most articles (39).
  • Research focused on the colon/small bowel, liver, and pancreaticobiliary systems, with keywords including 'liver injury,' 'inflammatory bowel disease,' 'management,' and 'endoscopy.'

Conclusions:

  • The analysis identified liver transplantation and inflammatory bowel disease as the most influential research topics within the COVID-19 and digestive disease landscape.
  • These findings highlight key areas of focus and potential future research directions.

Assessment of the Gastrointestinal System II: Health Perception Pattern

Assessing the gastrointestinal (GI) system is a complex process that begins with collecting subjective data. This data, collected through patient interviews, provides crucial insights into the patient's health history, perception patterns, and lifestyle habits, all contributing significantly to GI health.
Health Perception Patterns
Health perception patterns offer valuable insights into a patient's lifestyle habits and how they may impact their GI health. These patterns include:

What is Monogastric Digestion?01:50

What is Monogastric Digestion?

The human body contains a monogastric digestive system. In a monogastric digestive system, the stomach only contains one chamber in which it digests food. Several other animal species also have monogastric digestive systems, including pigs, horses, dogs, and birds. This chapter, however, focuses on the human digestive system.

Peptic Ulcer Disease III: Clinical Manifestations and Diagnostic Studies01:28

Peptic Ulcer Disease III: Clinical Manifestations and Diagnostic Studies

Peptic ulcer disease (PUD) presents with diverse symptoms depending on the location and severity of the ulcer. Clinical manifestations of peptic ulcer include dull pain and a burning sensation in the mid-epigastric region.
Few clinical manifestations differentiate gastric ulcers from duodenal ulcers. Distinctions in the location, timing, and pain relief are crucial for healthcare providers in differentiating between gastric and duodenal ulcers during clinical assessments.

Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy

Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

Imaging Studies III: Gastrointestinal Motility Studies and Virtual Colonoscopy

This lesson explores three gastrointestinal imaging techniques: radionuclide testing, colonic transit studies, and virtual colonoscopy.
Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and...

Gastritis-I: Introduction and Types01:27

Gastritis-I: Introduction and Types

Gastritis, defined by the inflammation or irritation of the stomach lining or gastric mucosa, manifests in several distinct forms: acute, chronic, reactive, and a specific subtype known as autoimmune metaplastic atrophic gastritis.
Acute gastritis presents as a sudden inflammation triggered by various stressors to the stomach lining, such as exposure to corrosive agents, local irritants like aspirin and other NSAIDs, alcohol consumption, radiation therapy, physical trauma, severe burns, sepsis,...
