Resumen
La inflamación sistémica en bebés prematuros puede causar importantes alteraciones visuales y del desarrollo neurológico. Este estudio propone una etio-patogénesis unificadora para estos resultados visuales adversos, denominados "visuopatía de prematuridad".
Área de la Ciencia:
- Oftalmología neonatal
- Pediatría del desarrollo neurológico
- Investigación de la inflamación sistémica
Sus antecedentes:
- Los bebés prematuros enfrentan riesgos significativos para patologías del sistema visual como retinopatía de prematuridad (ROP), deterioro visual cerebral (CVI) y deterioro del desarrollo neurológico (NDI).
- Las patologías distintas a menudo ocurren juntas, lo que sugiere una causa subyacente compartida.
Objetivo del estudio:
- Proponer una etio-patogénesis unificadora para las principales deficiencias visuales y del desarrollo neurológico en los bebés prematuros.
- Introducir el concepto de "visuopatía de la prematuridad" (VOP) que abarca los resultados visuales adversos (AVO).
Principales métodos:
- Revisión y síntesis de las pruebas publicadas.
- Desarrollo de un paradigma etiopatogénico por fases.
Principales resultados:
- Hipótesis de etiopatogénesis común que involucra inflamación sistémica intermitente y/o sostenida (ISSI).
- Propuso un modelo de tres fases: temprano (prenatal), intermedio (neonatal) y tardío (resultados).
Conclusiones:
- El ISSI se presenta como un factor central en el desarrollo de la VOP.
- El paradigma propuesto ofrece un marco para comprender y potencialmente intervenir en ROP, CVI y NDI en bebés prematuros.

Inflammatory Response I: Vascular and Cellular
12.4K
The inflammatory response is the body's defense against infection, injury, or irritation from bacteria, trauma, toxins, or heat. Inflammation helps locate and destroy pathogens and remove damaged tissue elements to heal the body. During this initial phase, fluid, blood products, and nutrients migrate to the injured area, resulting in redness, heat, swelling, ache, and loss of function. Moreover, signs of systemic inflammation include fever, increased WBC count, malaise, anorexia, nausea,...

Pathophysiology of Vomiting
1.1K
Vomiting is a complex physiological response to expel harmful or irritating substances from the body. It's a defensive mechanism triggered by stimuli like poisons, microbial toxins, cytotoxic drugs, and mechanical abdominal distension. The process is centrally coordinated by the vomiting (or emetic) center located in the medulla of the brainstem. This area, rich in muscarinic M1, histamine H1, neurokinin 1 (NK1), and serotonin 5-HT3 receptors, coordinates the act of vomiting through...

Pulmonary Hypertension: Classification and Pathogenesis
285
Pulmonary hypertension (PH) is a severe health condition in which the mean pulmonary arterial pressure increases to 25 mmHg or more, even when the body is at rest. This high pressure in the blood vessels that transport blood from the heart to the lungs can cause various symptoms, including shortness of breath, can lead to right heart failure, and significantly affect the overall quality of life.
There are various classifications for PH, each relating to different underlying causes and also...

Inflammatory Response
7.1K
An inflammatory response is a localized, nonspecific immune reaction that occurs when a tissue is injured. It is characterized by redness, swelling, heat, and pain, which are commonly called the cardinal signs and symptoms of inflammation. Inflammation can sometimes result in a loss of function.
Inflammation can be triggered by various stimuli, such as impact, abrasion, chemical irritation, infections, and extreme hot or cold temperatures. These can damage cells and connective tissue fibers,...

Fetal Circulation
1.4K
Fetal circulation is a unique system that facilitates the exchange of gases, nutrients, and waste products between the developing fetus and the mother. This intricate process takes place through a special organ called the placenta.
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...
