Insights

Host response to infection is controlled by circadian rhythms. This review explores the molecular clock

Area of Science:

  • Chronobiology
  • Immunology
  • Neonatal Medicine

Background:

  • Circadian rhythms are crucial for host adaptation to environmental changes.
  • Host response to infections, including sepsis, is significantly influenced by circadian control.
  • Existing research predominantly focuses on adult populations, with limited understanding of neonatal circadian biology.

Purpose of the Study:

  • To review the molecular clock's role in immunity and adult sepsis.
  • To highlight the importance of circadian rhythms during neonatal development.
  • To identify challenges and opportunities in managing neonatal sepsis by integrating circadian biology.

Main Methods:

  • Literature review of circadian biology, molecular clock mechanisms, and immune responses.
  • Synthesis of existing knowledge on adult sepsis and circadian rhythms.
  • Exploration of neonatal development and emerging circadian rhythms.

Main Results:

  • The molecular clock plays a critical role in regulating immune responses and influencing sepsis outcomes in adults.
  • Neonatal and early infancy are critical periods for the establishment of circadian rhythms.
  • Understanding these emerging rhythms is key to addressing neonatal sepsis.

Conclusions:

  • Circadian biology offers a novel perspective for understanding and managing neonatal sepsis.
  • Integrating knowledge of the molecular clock into neonatal care can improve outcomes.
  • Further research is needed to fully elucidate the impact of circadian rhythms on neonatal immunity and sepsis.

Circadian Rhythms and Gene Regulation

The biological clock is involved in many aspects of regulating complex physiology in all animals. It was in 1935 when German zoologists, Hans Kalmus and Erwin Bünning, discovered the existence of circadian rhythm in Drosophila melanogaster. However, the internal molecular mechanisms behind the circadian clock remained a mystery until 1984, when Jeffrey C. Hall, Michael Rosbash, and Michael W. Young discovered the expression of the Per gene oscillating over a 24-hour cycle. In subsequent...

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...

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...
