まとめ
頸動脈解離(CeAD)はカイロプラクティック操作後ではまれであるが、関連症例は椎骨動脈解離を有する若年女性に多い。年間数百万件の手技が行われているにもかかわらず、絶対リスクは依然として極めて低い。
科学分野:
- 神経学
- 血管医学
- 公衆衛生
背景:
- 頸動脈解離(CeAD)は、若年成人における虚血性脳卒中の重要な原因である。
- 米国では年間数百万件のカイロプラクティック頸部操作が行われており、CeADとの関連については議論がある。
研究 の 目的:
- カイロプラクティック頸部操作とCeADの関連を調査すること。
- 操作関連CeADの臨床的特徴を特定すること。
主な方法:
- CeAD症例(n=4023)を対象とした多施設共同STOP-CADレジストリの解析。
- 操作関連CeADと非操作関連CeADの人口統計学的および臨床的特徴の比較。
- 操作関連CeADに関連する要因を特定するための多変量ロジスティック回帰分析。
主要な成果:
- レジストリにおけるCeAD症例の約5%が、事前のカイロプラクティック操作を報告した。
- 操作関連CeADは、若年女性、糖尿病のない患者、および首の痛みを有する患者により頻繁に発生した。
- 操作関連症例では、孤立性椎骨動脈解離のオッズが高いことが注目された。
結論:
- 手技件数が多いにもかかわらず、カイロプラクティック操作後のCeADの絶対リスクは非常に低い。
- 操作関連CeAD症例は、若年女性や椎骨動脈が関与することが多い、特徴的な臨床的特徴を示す。
- 因果関係は不明のままである:操作が誘因となるのか、あるいは早期のCeAD症状が操作を促すのか。

Diagnosing Acidosis and Alkalosis
1.1K
Diagnosing acid-base imbalances involves systematically analyzing arterial blood samples, focusing on three key measurements: pH, bicarbonate (HCO3−) concentration, and carbon dioxide partial pressure (PCO2). This analysis follows a four-step process that helps identify the imbalance's underlying cause and nature.
First, the pH level is assessed to determine whether the blood pH is normal (7.35–7.45), low (acidosis), or high (alkalosis).
Next, the PCO2 and...

Manipulation and Analysis
293
GIS manipulation and analysis functions are vital for decision-making and planning. These activities range from data retrieval tasks, such as selecting information based on specific criteria, to advanced analytical techniques that address complex spatial problems.One critical GIS analysis method is overlaying, which combines multiple data layers to examine impacts. For example, overlaying a river-dammed lake boundary with road networks can identify affected infrastructure. Another common...

Arteries and Arterioles
6.3K
Arteries, the vasculature responsible for transporting blood from the heart, possess robust walls capable of enduring the elevated pressures exerted by the heartbeat. Arteries near the heart are especially thick-walled and enriched with elastic fibers across their three tunics, classifying them as elastic or conducting arteries. These arteries, usually with a diameter exceeding 10 mm, are characterized by their ability to dilate in response to the blood pumped from the heart's ventricles...

Arteries of Lower Limbs
4.3K
The external iliac artery transitions out of the body cavity, entering the femoral region of the lower leg, and is renamed the femoral artery at the point where it traverses the body wall. This artery is responsible for the distribution of blood to the thigh's deep muscles and the skin's ventral and lateral regions, achieved through several minor branches and the lateral deep femoral artery, which also spawns a lateral circumflex artery. The knee area receives blood from the genicular...

Arteries of the Upper Limbs
2.2K
The subclavian artery transitions into the axillary artery as it exits the chest and enters the axillary region. This artery is critical for supplying blood to the shoulder area, including the head of the humerus, through the humeral circumflex arteries. As the vessel continues into the upper arm or brachium, it becomes the brachial artery. This artery plays a key role in vascularizing the brachial region and bifurcates at the elbow into several branches. These branches include the deep...

Overview of Systemic Arteries
1.8K
The human body is a complex, well-organized machine, and at the heart of its operations lies the circulatory system. This network of blood vessels, which includes systemic arteries, plays a vital role in maintaining life by transporting nutrients, oxygen, and waste products to and from cells throughout the body.
Systemic circulation is the part of the cardiovascular system that carries oxygenated blood away from the heart to the body's tissues and returns deoxygenated blood back to the...
