Chronopharmacokinetics: Circadian Rhythms and Influence on Drug Response

104
Circadian rhythms are cyclic changes that are crucial in plasma drug concentrations. Various standard circadian parameters, including core body temperature, heart rate, and other cardiovascular factors, directly impact disease states and the therapeutic response to drug therapy.
The time of drug administration is an important factor to consider, as it can influence the toxic dose of a drug. For example, a study conducted by Prins et al. in 1997 examined the effects of the timing of...

Circadian Rhythms and Gene Regulation

4.1K
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...

Handwashing II: Pre-procedure and Initial Procedure Steps

992
The pre-procedure steps of handwashing include removing jewelry and rolling up sleeves. However, many organizations allow staff to wear wedding rings.
The hand washing procedure itself includes the following steps. First, cover cuts, if any, on hands with a waterproof dressing. Cuts and abrasions can become contaminated with bacteria hindering the ability to clean the area thoroughly. In addition, repeated hand washing can worsen an injury.  The nails must be short and clean, without nail...

Healthcare Associated Infections II: Preventive Measures

2.7K
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...

Standard Precaution

2.1K
Standard precautions are the minimum infection control safeguards used while caring for all patients, irrespective of their disease condition. They help prevent the spread of common infectious microorganisms to healthcare workers, patients, and visitors in all healthcare settings.
Hand hygiene is the most crucial means to prevent the transmission of disease. Employers are legally required to provide their workers with personal protective equipment (PPE) to minimize exposure or contact with...

Area of Science:

  • Chronobiology
  • Public Health
  • Sleep Science

Background:

  • Circadian rhythms, influenced by light-dark cycles and other synchronizers, govern human life patterns like sleep, eating, and activity.
  • Existing knowledge on circadian rhythms and health provides a foundation for future health promotion strategies.
  • Circadian hygiene, distinct from social hygiene, necessitates expert and public discourse.

Purpose of the Study:

  • To summarize current knowledge on factors affecting circadian rhythms.
  • To discuss future health promotion perspectives based on circadian hygiene.
  • To emphasize the dual role of individual and societal involvement in circadian hygiene.

Main Methods:

  • Literature review of factors influencing circadian rhythms.
  • Synthesis of current knowledge on circadian rhythms and health implications.
  • Discussion of public health policies and individual habits related to circadian hygiene.

Main Results:

  • Circadian hygiene integrates individual behaviors and societal practices.
  • Effective circadian hygiene requires aligning public health policies with internal biological rhythms.
  • Individual healthy habits necessitate an understanding of personal circadian rhythms.

Conclusions:

  • Circadian hygiene is a product of both individual and societal engagement.
  • Adopting circadian hygiene involves developing public health policies and personal healthy habits.
  • Future research and implementation of circadian hygiene depend on societal willingness to adapt.
