Insights

Antibiotics do not prevent preterm birth (PTB). A review of clinical trials found mixed results, and routine antibiotic prophylaxis is not recommended for preventing PTB.

Area of Science:

  • Obstetrics and Gynecology
  • Neonatal Medicine
  • Infectious Diseases

Background:

  • Preterm birth (PTB) is a leading cause of infant mortality and illness.
  • Infection is a known risk factor for PTB.

Purpose of the Study:

  • To review scientific literature on antibiotic use for PTB prevention.
  • To evaluate the efficacy of antibiotics in preventing PTB.

Main Methods:

  • PubMed database search for clinical trials and meta-analyses (1990-2011).
  • Keywords: "antibiotics or antimicrobials" and "preterm."
  • Full-text review of 31 selected studies.

Main Results:

  • Sixty-seven abstracts were initially identified.
  • Thirty-one studies (26 trials, 5 meta-analyses) were reviewed.
  • Antibiotic use for PTB prevention yielded mixed results, with no clear overall benefit.

Conclusions:

  • Routine antibiotic prophylaxis is not advised for PTB prevention.
  • Further research may be needed to clarify specific scenarios, if any, where antibiotics could be beneficial.

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,...

Transmission-based Precautions I: Contact, Enteric, and Droplets

Transmission-based precautions are for patients known to be infected or suspected to be infected or colonized with organisms that pose a significant risk to others. Some transmission-based precautions include contact, enteric, and droplet.
Contact Precautions:
Contact precautions are the measures taken to prevent the transmission of infectious agents, especially epidemiologically important microorganisms such as MRSA or influenza, primarily transmitted through direct or indirect contact with an...

Development of Human Microbiota

The human microbiota begins developing at birth and undergoes continual change as we age. Infancy marks a critical period of microbial sensitivity, offering a “window of opportunity” during which beneficial microbes help mature the immune system. By age three, children typically develop a more stable and diverse microbial community. Newborns acquire microbes from their immediate environment; vaginal delivery favors maternal vaginal microbes, while cesarean births favor microbes from the skin...
Antimicrobial Effectiveness01:28

Antimicrobial Effectiveness

The effectiveness of antimicrobial agents depends on various factors influencing their ability to eliminate microbial populations. Larger microbial populations require more time for complete eradication, emphasizing the importance of population size analysis when evaluating antimicrobial efficacy.Microbial resistance to antimicrobial agents varies significantly. Highly resilient microorganisms include endospores, gram-negative bacteria, and non-enveloped viruses, while prions are exceptionally...

Healthcare Associated Infections II: Preventive Measures

Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.
The best practices for preventing healthcare-associated infections include hand hygiene, patient risk...

Urinary Tract Infection III: Diagnostic Studies and Interprofessional Care

A healthcare provider can diagnose a urinary tract infection (UTI) through several methods:Medical History and Symptoms: The provider will take a detailed medical history and ask about symptoms such as frequent urination, burning sensation during urination, and lower abdominal pain.Urinalysis: A clean-catch urine sample is collected in a sterile container and tested for the presence of bacteria, white blood cells (leukocytes), nitrites, blood, and protein. The presence of leukocytes and...
