Chronopharmacokinetics: Circadian Rhythms and Influence on Drug Response

450
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...

Alterations in Blood Pressure

2.4K
Alterations in blood pressure, such as hypertension (high blood pressure) and hypotension (low blood pressure), significantly affect human health. Understanding these conditions' classifications, causes, and symptoms is essential for effective management and treatment.
Hypertension (High blood pressure)
Hypertension occurs when blood pressure readings consistently exceed the normal range. It is diagnosed when systolic blood pressure (the top number, indicating pressure while the heart...

Special considerations while measuring blood pressure

1.5K
When assessing blood pressure (BP), healthcare professionals must consider various factors and potential unexpected outcomes to ensure accurate readings and provide proper patient care. Adhering to these guidelines is essential to achieving the most reliable results.
Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.

Hypertension III: Clinical Manifestations and Diagnostic Studies

710
Hypertension is asymptomatic and also referred to as the "silent killer" until it progresses to a severe stage or causes target organ disease. Patients may experience symptoms stemming from the strain on blood vessels and tissues in various organs or the heart's increased workload.Physical exams might show no abnormalities other than high blood pressure. Signs of vascular damage, when present, correspond to the organs supplied by the affected vessels, leading to target organ damage. For...

Measurement of Blood Pressure01:17

Measurement of Blood Pressure

3.9K
Assessing blood pressure is a standard procedure executed in virtually all medical environments. The method utilized today was established over a hundred years ago by an innovative Russian doctor, Dr. Nikolai Korotkoff. The soft ticking noise, known as Korotkoff sounds, heard while taking blood pressure readings results from turbulent blood flow within the vessels. The apparatus required for this procedure includes a sphygmomanometer, a blood pressure cuff attached to a gauge, and a...

Summary
This summary is machine-generated.

Seasonal changes affect blood pressure dipping patterns differently in White and Asian populations. Reverse dippers decrease in winter, but racial variations influence how these changes redistribute among different blood pressure dipping groups.

Area of Science:

  • Cardiology
  • Circadian Rhythms
  • Public Health

Background:

  • Normal blood pressure (BP) exhibits a circadian rhythm with nocturnal dipping.
  • Limited research exists on seasonal variations in BP dipping patterns across different ethnicities.
  • Understanding these variations is crucial for personalized cardiovascular health management.

Purpose of the Study:

  • To investigate nocturnal blood pressure dipping patterns in White and Asian populations.
  • To compare seasonal differences (summer vs. winter) in BP dipping between these ethnic groups.
  • To explore the redistribution of 'reverse dippers' across different dipping categories seasonally and ethnically.

Main Methods:

  • Ambulatory Blood Pressure Monitor (ABPM) recordings were collected from 220 patients.
  • The study included equal numbers of White patients (Ireland) and Asian patients (Singapore).
  • Data was gathered during summer (May-June) and winter (October-December) periods.

Main Results:

  • Both Irish and Singaporean populations showed a reduction in 'reverse dippers' from summer to winter.
  • In Singapore, reverse dippers redistributed mainly to the 'dipper' category.
  • In Ireland, reverse dippers redistributed to both 'dipper' and 'extreme dipper' categories, with significant seasonal increases in nocturnal diastolic pressure and dipping duration.

Conclusions:

  • The number of 'reverse dippers' decreases in winter, irrespective of race or ambient temperature.
  • Ethnic differences significantly influence the redistribution patterns of decreasing 'reverse dippers'.
  • These findings have implications for the timing and management strategies for individuals classified as 'reverse dippers'.
