Enteral Nutrition II: Nasointestinal and Gastrostomy Feeding

55
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.

What is Monogastric Digestion?01:50

What is Monogastric Digestion?

70.4K
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.

Enteral Nutrition I: Orogastric and Nasogastric Feeding

169
Enteral nutrition delivers nutrients directly to the stomach or small intestine through a tube. This method is appropriate for patients who cannot eat but still have a functioning digestive system. It is also beneficial for individuals with swallowing difficulties, anorexia, malabsorption, or those who have undergone gastrointestinal (GI) surgery.
Orogastric (OG) and nasogastric (NG) feeding are two standard methods used for enteral nutrition. Enteral nutrition is often preferred over...

Oral Cavity01:11

Oral Cavity

389
The oral cavity, or the mouth, is a complex structure in humans that plays a vital role in our day-to-day lives. Its role is not only in chewing and swallowing food; it also plays a role in speech and facial expressions.
Teeth: The teeth are the hardest structures in our bodies. Humans have two sets of teeth throughout their lifetime: deciduous (baby) teeth and permanent teeth. Each tooth consists of several parts: the crown (visible part), the root (embedded in the jaw), enamel (hard outer...

Tumor Immunotherapy01:27

Tumor Immunotherapy

464
Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.

Summary
This summary is machine-generated.

Food oral immunotherapy (OIT) offers a treatment for immunoglobulin E (IgE)-mediated food allergies by gradually introducing allergens. This approach is particularly effective and well-tolerated in infants and toddlers, potentially leading to sustained unresponsiveness.

Area of Science:

  • Allergy and Immunology
  • Clinical Therapeutics
  • Pediatric Medicine

Background:

  • Immunoglobulin E (IgE)-mediated food allergy is a significant health concern.
  • Current Canadian guidelines support food oral immunotherapy (OIT) as a treatment option.
  • OIT involves supervised, incremental exposure to food allergens to induce tolerance.

Purpose of the Study:

  • To provide an overview of food oral immunotherapy (OIT).
  • To discuss the role of non-allergist clinicians in managing patients undergoing OIT.
  • To highlight the benefits of OIT, especially in pediatric populations.

Main Methods:

  • Review of current clinical practice guidelines for OIT.
  • Discussion of OIT protocols and patient management.
  • Emphasis on the supervised administration of gradually increasing allergen doses.

Main Results:

  • OIT is recommended in Canadian clinical practice for food allergy treatment.
  • The infant and toddler population shows particular tolerance and benefit from OIT.
  • OIT aims for desensitization and can achieve sustained unresponsiveness or remission.

Conclusions:

  • Food oral immunotherapy (OIT) is a viable treatment for IgE-mediated food allergies.
  • Prioritizing OIT in infants and toddlers can yield optimal outcomes, including sustained unresponsiveness.
  • Non-allergist clinicians have a crucial role in supporting patients throughout OIT.
