Neonatal sepsis is divided into two categories: early-onset sepsis (EOS) and late-onset sepsis (LOS). EOS refers to sepsis presenting in the first 7 days of life (although some refer to EOS as within the first 72 hours of life), with LOS referring to presentation of sepsis after 7 days (or 72 hours, depending on the system used).
Late-onset sepsis (LOS), defined as onset of symptoms after 72 hours of life, is generally caused by transmission of pathogens from the environment after delivery. Infants requiring intravascular catheters and other invasive procedures are at increased risk for developing LOS. [3]
Sepsis is a potentially life-threatening condition that arises when the body's response to infection causes injury to its own tissues and organs. [ 4 ] [ 7 ] This initial stage of sepsis is followed by suppression of the immune system . [ 8 ]
The pathophysiology of septic shock is not entirely understood, but it is known that a key role in the development of severe sepsis is played by an immune and coagulation response to an infection. Both pro-inflammatory and anti-inflammatory responses play a role in septic shock. [ 8 ]
GBS it is also an important pathogen in a diversity of fish species, leading to serious economic losses in many species of fish worldwide. GBS causes severe epidemics in farmed fish, causing sepsis and external and internal hemorrhages. GBS infection has been reported from wild and captive fish and has been involved in epizootics in many countries.
Relatively common causes include sepsis, surgery, major trauma, cancer, and complications of pregnancy. [1] Less common causes include snake bites, frostbite, and burns. [1] There are two main types: acute (rapid onset) and chronic (slow onset). [1] Diagnosis is typically based on blood tests. [2]
In patients with sepsis, septic shock, or multiple organ dysfunction syndrome that is due to major trauma, the rs1800625 polymorphism is a functional single nucleotide polymorphism, a part of the receptor for advanced glycation end products (RAGE) transmembrane receptor gene (of the immunoglobulin superfamily) and confers host susceptibility to ...
The origins of pathophysiology as a distinct field date back to the late 18th century. The first known lectures on the subject were delivered by Professor August Friedrich Hecker at the University of Erfurt in 1790, and in 1791, he published the first textbook on pathophysiology, Grundriss der Physiologia pathologica, [2] spanning 770 pages.
