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

609
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...

Parentral Nutrition: Centeral and Peripheral Parental Nutrition

679
Parenteral Nutrition (PN) delivers essential nutrients directly into the bloodstream, bypassing the digestive system. It is commonly used for individuals with severe digestive disorders or conditions that prevent normal nutrient absorption.
PN can be administered through two primary routes:
1. Central Parenteral Nutrition (CPN):
CPN involves delivering a high concentration of nutrients through a large vein. This is typically achieved using a Peripherally Inserted Central Catheter (PICC) or,...

Organisms exhibit remarkable metabolic diversity, categorized based on how they acquire energy and carbon. These strategies enable survival in various ecological niches and are essential for maintaining energy flow and nutrient cycling within ecosystems.Energy and Carbon SourcesOrganisms are classified as phototrophs or chemotrophs based on energy acquisition. Phototrophs use light as their energy source, while chemotrophs rely on oxidizing chemical compounds. Further differentiation arises...

Absorption of Nutrients01:19

Absorption of Nutrients

2.5K
Absorption refers to taking dietary nutrients from the intestinal lumen for transportation throughout the body. After digestion in the small intestine, carbohydrates, proteins, and fats are broken down into simpler forms. These essential macronutrients and other vital substances, such as vitamins, minerals, and water, are then prepared for absorption into the bloodstream.
Enterocytes, which are specialized polar epithelial cells, line the mucosa of the small intestinal walls. These cells...

Proteins: Dietary Sources and Requirements

1.3K
Consuming animal-based products offers high-quality proteins that contain optimal levels and combinations of essential amino acids, crucial for tissue repair and growth. Foods like eggs, milk, fish, and most meats are a source of complete proteins. Legumes and cereals are abundant in proteins; however, they typically lack a full range of essential amino acids. As a result, they are considered incomplete protein sources. Some plant sources like soybeans, quinoa, and amaranth do contain complete...

The Effect of Aging on Tissues01:19

The Effect of Aging on Tissues

3.1K
Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...

Área de la Ciencia:

  • Inmunología Nutricional
  • Gerontología
  • Investigación del Estrés Oxidativo

Sus antecedentes:

  • La inmunonutrición implica intervenciones dietéticas para potenciar la función inmune.
  • Los nutrientes clave incluyen aminoácidos, vitaminas, minerales y flavonoides.
  • La teoría oxi-inflamm-aging vincula la dieta, la inmunidad y la longevidad a través de vías antioxidantes y antiinflamatorias.

Objetivo del estudio:

  • Investigar cómo los inmunonutrientes modulan la actividad inmunitaria y la longevidad.
  • Explorar los mecanismos antioxidantes y antiinflamatorios involucrados.
  • Examinar el papel de nutrientes específicos como la vitamina C, E, D, zinc, selenio y flavonoides en el envejecimiento.

Principales métodos:

  • Revisión y examen teórico de la investigación existente sobre inmunonutrientes y envejecimiento.
  • Análisis de la teoría oxi-inflamm-aging.
  • Exploración de las vías moleculares influenciadas por nutrientes específicos (por ejemplo, señalización P21, expresión génica del gen SKN-1).

Principales resultados:

  • La vitamina C puede aumentar la longevidad si se consume temprano.
  • La vitamina E puede reducir la mortalidad por enfermedades al inhibir el daño oxidativo y activar vías anticancerígenas.
  • La vitamina D puede reducir el envejecimiento al influir en los genes de respuesta al estrés y la agregación de proteínas.
  • El zinc regula la actividad de las células inmunitarias.
  • El selenio mejora la homeostasis redox celular y la función inmune.
  • Los flavonoides protegen contra los fenotipos del envejecimiento al respaldar la salud neuronal y metabólica.

Conclusiones:

  • Inmunonutrientes específicos muestran potencial para mitigar los procesos de envejecimiento y mejorar la función inmune.
  • Estos efectos están vinculados a mecanismos de protección antioxidante, antiinflamatoria y celular.
  • Se requieren estudios exhaustivos adicionales para validar estos hallazgos y sus implicaciones clínicas.
