Insights

Infections and intrauterine inflammation are key causes of preterm birth. Aberrant inflammatory responses, regardless of infection pathway, can trigger premature labor via prostaglandin overproduction.

Area of Science:

  • Perinatology
  • Reproductive Immunology
  • Microbiology

Background:

  • Preterm birth is a leading cause of perinatal morbidity and mortality.
  • Infection and intrauterine inflammation are frequently associated with preterm birth induction.
  • Research indicates infections precede labor induction, with a subclinical latency phase.

Purpose of the Study:

  • To investigate the link between infection, inflammation, and preterm birth.
  • To explore the role of microbial pathways in initiating preterm labor.
  • To understand the impact of inflammatory mediators on premature uterine contractions.

Main Methods:

  • Review of animal models and human research on infection and preterm birth.
  • Analysis of microbial pathways accessing the amniotic cavity.
  • Examination of prostaglandin and nitric oxide involvement in inflammatory-induced labor.

Main Results:

  • Ascending microbial routes from the vagina and cervix are common pathways to the uterus.
  • Infection and inflammation precede labor induction, with a latent phase.
  • Overproduction of prostaglandins and nitric oxide during inflammation can trigger uterine contractions.

Conclusions:

  • Aberrant inflammatory responses, irrespective of the route of microbial entry, can precipitate preterm labor.
  • Prostaglandin overproduction is a critical factor in infection-induced premature uterine contractions.
  • Understanding these mechanisms is crucial for preventing preterm birth.

Development of the Oral Microbiota01:28

Development of the Oral Microbiota

The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...

Acute Inflammation II: Local and Systemic Effects

Acute inflammation produces a coordinated set of local and systemic changes that limit injury, eliminate pathogens, and initiate repair. These responses arise within minutes of infection, trauma, or chemical insult and are driven by vascular alterations and leukocyte-derived mediators. When the stimulus resolves, the reaction typically abates within days.Local EffectsAt the site of injury, arteriolar vasodilation increases blood flow, resulting in redness and warmth. Simultaneously, increased...

Factors Affecting the Risk of Infection01:26

Factors Affecting the Risk of Infection

The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

Inflammation: Introduction01:28

Inflammation: Introduction

Inflammation is a fundamental, protective biological response of vascularized tissues to cellular injury, infection, or harmful stimuli. Its primary function is to eliminate the initial cause of injury, clear necrotic cells and damaged tissue, and initiate the necessary repair processes.Cardinal SignsAcute inflammation presents with classic signs. Redness results from vasodilation and increased blood flow. Heat is due to increased metabolism and circulation. Swelling results from the...

Infection01:20

Infection

When a pathogen enters the body and reproduces, it can cause an infection, damage body cells, and cause illness symptoms that eventually lead to disease. Therefore, its prevention requires breaking the chain of infection.
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...
