まとめ
偏頭痛のリスクは 月経周期に関連しており 新月の前には 34%増加します 偏頭痛の発生におけるこの円月律は,背後にあるクロノバイオロジカルメカニズムを明らかにする可能性があります.
科学分野:
- クロノバイオロジー
- 神経学
- 流行病学
背景:
- 偏頭痛はよくある神経疾患で,リズムがよくわかっていない.
- 日常および季節性片頭痛のパターンは知られていますが,月経 (月経) リズムについてはほとんど研究されていません.
- サーカルナルのパターンの調査は頭痛の予測を向上させ,予防的な治療のタイミングを最適化することができます.
研究 の 目的:
- 月経周期と成人の頭痛の発生との関連を調査する.
- この関係における睡眠と月経周期のタイミングの 潜在的な仲介的な役割を探るため
- 人口と個人のレベルの両方でサーカルナルのリズムを分析する.
主な方法:
- 予期的なコホート研究 (2016年3月~2017年10月) の二次分析で,エピソード性片頭痛の98人の成人が参加した.
- 参加者は頭痛の発生と月経周期データを記録するために毎日2回電子日記を使用しました.
- 手首のアクティグラフィは6週間使用され,統計分析では,コバリアートに調整して,サークルナルのリズムを調査した.
主要な成果:
- 人口レベルでは,頭痛リスクの有意な円月リズムが観察されました.
- 個別分析では 満月と比べると 新月直前の片頭痛の確率が 34%高いことが分かりました
- 睡眠パターンも月経周期のタイミングも,月相と頭痛の発生の間の観察された関係を有意に媒介しなかった.
結論:
- エピソード性片頭痛患者における頭痛リスクは,月経周期によって有意に変化します.
- 睡眠や月経周期の要因とは無関係に 根本的なクロノバイオロジカルメカニズムが 偏頭痛に影響を及ぼすことを示唆しています
- これらの結果を確認し,円月律の個々の変動性を理解するために,さらなる研究が必要である.

01:53Cause and Effect
11.3K
While variables are sometimes correlated because one does cause the other, it could also be that some other factor, a confounding variable, is actually causing the systematic movement in our variables of interest. For instance, as sales in ice cream increase, so does the overall rate of crime. Is it possible that indulging in your favorite flavor of ice cream could send you on a crime spree? Or, after committing crime do you think you might decide to treat yourself to a cone?

01:42Simple Harmonic Motion and Uniform Circular Motion
4.5K
While simple harmonic motion and uniform circular motion may be two separate concepts, they correlate and interlink with each other. Simple harmonic motion is an oscillatory motion in a system where the net force can be described by Hooke's law, while uniform circular motion is the motion of an object in a circular path at constant speed.
There is an easy way to produce simple harmonic motion by using uniform circular motion. For instance, consider a ball attached to a uniformly rotating...

01:16Gravitation
6.7K
In the years before Newton, a general belief prevailed that different laws governed objects in the sky than objects on Earth. When Kepler wrote down the three laws of planetary motion, explaining in detail the geometrical properties of the planetary orbits around the Sun, there was no immediate idea to discern their connection with more fundamental laws. It was Isaac Newton who, in 1665–66, figured out the connection between planetary motion, the motion of the moon around the Earth, and...

01:22Hormonal Regulation of the Menstrual Cycle
688
The ovarian cycle regulates endometrial changes throughout a single menstrual cycle via the coordinated action of gonadotrophin-releasing hormone (GnRH) and gonadotrophins.
At puberty, GnRH begins a pulsatile release pattern, which triggers the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The frequency and amplitude of GnRH pulses vary across the menstrual cycle, with faster pulses favoring LH release and slower pulses favoring FSH...

01:19The Menstrual Cycle
1.4K
The menstrual cycle is a recurrent sequence of changes in the uterine endometrium, specifically its functional layer, the stratum functionalis. This cycle prepares the uterus for potential pregnancy. This cycle typically spans 21–35 days, averaging 28 days, and aligns with the ovarian cycle, regulated by fluctuating levels of ovarian hormones, primarily estrogen and progesterone.
The menstrual phase occurs from days 1 to 5 and involves the shedding of the stratum functionalis, as a...

2.7K
The origin of Earth's ocean tides has been a subject of continuous investigation for over 2000 years. However, the work of Newton is considered to be the beginning of the proper understanding of the phenomenon. Ocean tides are the result of gravitational tidal forces. These same tidal forces are present in any astronomical body; they are responsible for the internal heat that creates the volcanic activity on Io, one of Jupiter's moons, and the breakup of stars that get too close to...
