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

468
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...

Composition of Body Fluids01:29

Composition of Body Fluids

1.5K
Water functions as a solvent accommodating various solutes, which can be categorized under electrolytes and non-electrolytes. Non-electrolytes are usually held together by covalent bonds, restricting them from dissociating in solution, thereby leading to a lack of electrically charged components upon dissolving in water. They are predominantly organic molecules, such as glucose, creatinine, and urea. Electrolytes, on the other hand, are compounds that can break down into ions in water.

Anatomy of the Intestines

84.5K
Although digestion of proteins, carbohydrates, and lipids may begin in the stomach, it is completed in the intestine. The absorption of nutrients, water, and electrolytes from food and drink also occurs in the intestine. The intestines can be divided into two structurally distinct organs—the small and large intestines.
Small Intestines
The small intestine is an ~7 meter-long tube with an inner diameter of just 2.5 cm. Since most nutrients are absorbed here, the inner lining of the...

Enteral Nutrition II: Nasointestinal and Gastrostomy Feeding

376
Enteral nutrition encompasses various methods of delivering nutrition directly to the gastrointestinal (GI) tract, bypassing traditional oral intake. It is particularly beneficial for patients who cannot eat by mouth but have a functioning digestive system. Key methods include nasointestinal feeding, gastrostomy, and jejunostomy, each suited to different clinical scenarios based on the patient's needs and condition.
Nasointestinal Feeding
Nasointestinal feeding involves placing a tube...

Inflammatory Bowel Disease II: Crohn's Disease

484
Introduction
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...

Pharmacokinetics in Obese Patients: Drug Absorption and Distribution01:25

Pharmacokinetics in Obese Patients: Drug Absorption and Distribution

53
Obesity significantly alters the pharmacokinetic processes of drug absorption and distribution, presenting unique challenges in medical treatment. The increased fat tissue and decreased lean muscle in obese individuals can significantly affect how drugs are absorbed into the body and distributed across different tissues. This alteration can lead to variances in the effectiveness and safety of medications, necessitating adjustments in dosing or drug selection for obese patients.One notable...

Summary

Low muscle mass is prevalent in type 2 intestinal failure (IF). Both bioelectric impedance analysis (BIA) and computed tomography (CT) can assess body composition, but CT better identifies low muscle mass in IF patients.

Area of Science:

  • Clinical Nutrition
  • Body Composition Analysis
  • Gastroenterology

Background:

  • Body composition measurement is crucial for nutritional assessment.
  • Data on assessment modalities for type 2 intestinal failure (IF) are lacking.
  • This study addresses the prevalence of low muscle mass and quality in type 2 IF.

Purpose of the Study:

  • To evaluate low muscle mass and quality prevalence in type 2 IF.
  • To compare bioelectric impedance analysis (BIA) and computed tomography (CT) for body composition assessment in type 2 IF.
  • To establish the utility of BIA and CT in this patient population.

Main Methods:

  • Cross-sectional study of 44 type 2 IF patients at a UK national IF center.
  • Included patients with BIA and CT scans within 40 days of anthropometric measurement.
  • Collected demographic and clinical data.

Main Results:

  • Low muscle mass detected in 84.1% by CT and 68.2% by BIA.
  • Low muscle quality detected in 50% by CT and 90.1% by BIA.
  • Moderate correlation between CT and BIA for muscle mass (ρ=0.65), strong for body fat (ρ=0.79).

Conclusions:

  • Low muscle mass is common in type 2 IF, irrespective of assessment method.
  • Further research is needed to validate findings and explore interventions.
  • Highlights the need for body composition assessment in type 2 IF management.
