Infection

6.3K
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...

Healthcare Associated Infections II: Preventive Measures

2.3K
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...

Factors Affecting the Risk of Infection01:26

Factors Affecting the Risk of Infection

10.5K
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...

Steps in Outbreak Investigation

90
In the ever-evolving field of public health, statistical analysis serves as a cornerstone for understanding and managing disease outbreaks. By leveraging various statistical tools, health professionals can predict potential outbreaks, analyze ongoing situations, and devise effective responses to mitigate impact. For that to happen, there are a few possible stages of the analysis:

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

3.2K
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...

Summary

Puerperal infection (PI) risk can be predicted using a nomogram based on factors like vaginal exams and postpartum bleeding. Early detection and targeted antibiotics, especially for Escherichia coli, improve maternal outcomes.

Area of Science:

  • Obstetrics and Gynecology
  • Infectious Diseases
  • Medical Informatics

Background:

  • Puerperal infection (PI) is a significant cause of maternal morbidity and mortality globally.
  • Identifying high-risk factors and pathogens is crucial for prevention and treatment.

Purpose of the Study:

  • To analyze risk factors and identify pathogenic bacteria in puerperal infection.
  • To develop a predictive nomogram for PI risk.
  • To provide clinical guidance for PI management.

Main Methods:

  • A cohort of 525 pregnant women was divided into training (n=367) and testing (n=158) groups.
  • Logistic regression identified significant risk factors for PI.
  • Nomogram performance was validated using ROC curves, calibration, and decision curve analyses.
  • Blood cultures and antibiotic sensitivity tests were performed on PI patients.

Main Results:

  • Six risk factors for PI were identified: parity, vaginal examinations, postpartum bleeding, prior antibiotic use, induced labor, and indwelling catheter.
  • The nomogram demonstrated high predictive accuracy (AUC training: 0.904, test: 0.890).
  • Escherichia coli was the predominant pathogen (89%), with high sensitivity to Meropenem, Imipenem, Piperacillin tazobactam, Ceftazidime, and Amoxicillin/Clavulanate (AMC).

Conclusions:

  • Controlling vaginal examinations (<4), postpartum hemorrhage (<414ml), and catheter indwelling time can reduce PI risk.
  • Antibiotics sensitive to Escherichia coli, such as Piperacillin tazobactam, Ceftazidime, and AMC, are recommended for suspected or diagnosed PI.
