Insights

Maternal antibiotic use before or during pregnancy increases children's risk of hospitalized infections. This association highlights potential impacts on the early life microbiome and immune development.

Area of Science:

  • Microbiome research
  • Pediatric infectious diseases
  • Reproductive health

Background:

  • The early life microbiome is crucial for immune system development.
  • Antibiotic use during pregnancy can disrupt the maternal microbiome.
  • This disruption may increase offspring's susceptibility to diseases.

Purpose of the Study:

  • To investigate the association between maternal antibiotic exposure (before and during pregnancy) and the risk of infection-related hospitalizations in children.
  • To explore how timing and duration of antibiotic exposure influence this risk.

Main Methods:

  • Utilized Danish national population-based databases for pregnancies from 1995-2009.
  • Followed live-born singletons from birth until a first infection-related hospitalization, death, age 14, emigration, or end-2009.
  • Defined exposure as maternal antibiotic prescriptions before and during pregnancy; outcome was infection-related hospitalization.

Main Results:

  • Maternal antibiotic exposure during pregnancy was linked to a higher risk of childhood infection-related hospitalization (HR 1.18, 95% CI 1.17-1.19).
  • Increased risks were observed with antibiotic prescriptions closer to birth and with more frequent prescriptions.
  • Antibiotic exposure before pregnancy also elevated the risk (HR 1.10, 95% CI 1.07-1.12).

Conclusions:

  • Antibiotic exposure before or during pregnancy is associated with an increased risk of hospitalized infections in children.
  • Potential mechanisms include alterations in the maternal microbiome and shared genetic/environmental factors.

Hospitals-II

Hospitals provide inpatient and outpatient services. Inpatient services provide care to patients that stay in the hospital for an extended period, ranging from days to months. Examples of inpatient services include intensive care units, hospital wards, or surgeries. Outpatient services provide care to patients who come to a hospital for a diagnostic or treatment but do not stay overnight —for example, diagnostic tests, surgical procedures, or health education.

Hospitals-I

Hospitals offer medical and surgical care to the sick and injured, along with accommodation while they recover. At the same time, they also provide outpatient, emergency, psychiatric, and rehabilitation services to meet various community needs. In addition to providing medical care, hospitals also act as hubs for medical research and training. Hospitals use clinical procedures and evidence-based practice standards to deliver patient care. To deliver safe and efficient care, a nurse must stay up...

What is Population Genetics?01:25

What is Population Genetics?

A population is composed of members of the same species that simultaneously live and interact in the same area. When individuals in a population breed, they pass down their genes to their offspring. Many of these genes are polymorphic, meaning that they occur in multiple variants. Such variations of a gene are referred to as alleles. The collective set of all the alleles within a population is known as the gene pool.

Conservation of Small Populations

Small population sizes put a species at extreme risk of extinction due to a lack of variation, and a consequent decrease in adaptability. This weakens the chances of survival under pressures such as climate change, competition from other species, or new diseases. Large populations are more likely to survive pressures such as these, as such populations are more likely to harbor individuals that have genetic variants that are adaptive under new stresses. Small populations are much less...
