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

407
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...

Aging

174
Aging is a complex biological phenomenon influenced by various processes that affect cellular and systemic functions. Several prominent theories attempt to explain its mechanisms, highlighting cellular limitations, oxidative damage, and hormonal changes as central factors in aging.
Cellular Clock Theory
The cellular clock theory posits that the human lifespan is closely tied to the finite capacity of cells to divide, a phenomenon governed by telomeres, which are protective caps at the ends of...

Inflammatory Bowel Disease IV: Pharmacological Management

177
Upon diagnosis, managing Inflammatory Bowel Disease (IBD) involves addressing several crucial aspects. The primary goals include resting the bowel, correcting malnutrition, and providing symptomatic relief. Resting the bowel may consist of medications to reduce inflammation and promote healing. Correcting malnutrition is essential, often requiring dietary adjustments and nutritional supplements. Symptomatic relief aims to ease pain, diarrhea, and other discomforts in IBD.

The Effect of Aging on Tissues01:19

The Effect of Aging on Tissues

2.4K
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...

Anatomy of the Intestines01:23

Anatomy of the Intestines

73.8K
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...

Renewal of Intestinal Stem Cells01:23

Renewal of Intestinal Stem Cells

2.7K
The intestinal epithelial lining rapidly renews every 4 to 5 days. The renewal is facilitated by intestinal stem cells (ISCs) located at the base of the crypt– a gland located at the bottom of each villus. ISCs divide asymmetrically to form new stem cells and progenitor daughter cells. The daughter cells are called transit-amplifying (TA) cells which move upwards along the crypt and either differentiate into absorptive cells– the enterocytes or secretory cells– including the...

Área de la Ciencia:

  • Gerontología
  • Inmunología
  • Gastroenterología

Sus antecedentes:

  • La inmunosenescencia intestinal es un aspecto clave del envejecimiento, que afecta a la salud de los ancianos.
  • El envejecimiento altera las células inmunes intestinales, el equilibrio de la microbiota y la integridad de la barrera.
  • Estos cambios están relacionados con enfermedades relacionadas con la edad.

Objetivo del estudio:

  • Revisar sistemáticamente los mecanismos de la inmunosenescencia intestinal.
  • Para analizar su asociación con enfermedades como infecciones y neurodegeneración.
  • Para resumir las estrategias terapéuticas actuales y emergentes.

  • Análisis de la función de las células inmunes, la microbiota y los cambios en la barrera.
  • Síntesis de datos sobre las asociaciones de enfermedades y las intervenciones.

Principales resultados:

  • La disfunción de las células inmunes, la disbiosis y los defectos de la barrera caracterizan la inmunosenescencia intestinal.
  • Se asocia con una mayor susceptibilidad a las infecciones, la inflamación crónica y las afecciones neurodegenerativas.
  • Las terapias dietéticas y microecológicas son prometedoras.

Conclusiones:

  • Comprender la inmunosenescencia intestinal es crucial para envejecer bien.
  • Dirigirse a la inmunidad intestinal ofrece potencial para la extensión de la vida útil.
