Chronopharmacokinetics: Circadian Rhythms and Influence on Drug Response

Chronopharmacokinetics: Circadian Rhythms and Influence on Drug Response

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...

Regulation of Stroke Volume

Regulation of Stroke Volume

The regulation of stroke volume, which is the amount of blood the heart pumps out during each heartbeat, is critical for maintaining a healthy circulatory system. Stroke volume is influenced by three main factors: preload, contractility, and afterload.
Preload refers to the degree of stretch on the heart before it contracts. It's analogous to the stretching of a rubber band; the more it's stretched, the more forcefully it snaps back. This concept is encapsulated in the Frank-Starling law of the...

Area of Science:

Epidemiology
Public Health
Sleep Medicine

Background:

Daytime napping is a widespread practice globally.
Increasing attention is being paid to the health implications of napping.

Purpose of the Study:

To conduct a meta-analysis evaluating the link between daytime napping and stroke risk.
To inform lifestyle modifications for stroke risk reduction.

Main Methods:

Searched Embase, PubMed, Web of Science, and PsycINFO databases for cohort studies up to October 2020.
Included eight studies with 524,408 participants and 5,875 stroke cases.
Performed meta-analysis and dose-response analysis.

Main Results:

The pooled relative risk (RR) for stroke was 1.47 (95% CI: 1.24-1.74).
Heterogeneity was reduced after excluding a study that did not adjust for sleep duration (RR: 1.38; 95% CI: 1.19-1.60).
A 3% increase in stroke risk was observed for every 10-minute increase in daytime napping duration.

Conclusions:

Daytime napping is significantly associated with an increased risk of stroke.
Further research is needed to understand the biological mechanisms.
Modifying napping habits may contribute to stroke prevention strategies.
