まとめ
モバイル脳卒中ユニット(MSU)は、血管内治療の対象となる脳卒中患者の治療時間を、標準的な救急医療サービス(EMS)と比較して大幅に短縮します。転帰と安全性は同様であり、MSUのワークフローの利点を強調しています。
科学分野:
- 神経学、救急医学、医療サービス研究
背景:
- モバイル脳卒中ユニット(MSU)は、急性虚血性脳卒中、特に静脈内血栓溶解療法の治療時間と転帰を改善します。臨床試験以外での血管内治療(EVT)適格患者に対するMSUの影響に関するデータは限られています。EVT適格患者に対するMSUワークフローの利点を標準的な救急医療サービス(EMS)と比較して調査することは非常に重要です。
研究 の 目的:
- 機械的血栓回収の対象となるMSU搬送患者とEMS搬送患者のワークフロー効率と治療時間を比較すること。この患者集団におけるMSUケアが主要な時間指標と臨床転帰に及ぼす影響を評価すること。
主な方法:
- 単一施設での機械的血栓回収データベース(2018年6月~2023年11月)の後ろ向き横断研究。MSU稼働時間内に搬送された患者を、MSU搬送群とEMS搬送群(マザーシップ)に分類。両群間の治療時間指標と臨床転帰の比較。
主要な成果:
- 66人の患者がMSUで搬送され、499人がEMSで搬送されました。MSU患者は、ドアから造影剤投与(41対62分)、ドアから穿刺(58対82分)、ドアから再灌流(96対127分)までの時間が有意に短縮されました(P<0.001)。最後の既知の発症から穿刺までの時間は、MSU患者の方が短縮されました(237対389分、P=0.021)。
結論:
- MSU搬送は、標準的なEMSと比較して、EVT適格脳卒中患者の時間の指標を有意に改善することに関連しています。90日時点での機能的転帰と脳室内出血率は、MSU群とEMS群で同等でした。MSUケアは、安全性や長期転帰を損なうことなく、EVT適格脳卒中患者のワークフロー上の利点を提供します。

Lattice Centering and Coordination Number
11.4K
The structure of a crystalline solid, whether a metal or not, is best described by considering its simplest repeating unit, which is referred to as its unit cell. The unit cell consists of lattice points that represent the locations of atoms or ions. The entire structure then consists of this unit cell repeating in three dimensions. The three different types of unit cells present in the cubic lattice are illustrated in Figure 1.

Measurement: Standard Units
78.7K
Every measurement provides three kinds of information: the size or magnitude of the measurement (a number), a standard of comparison for the measurement (a unit), and an indication of the uncertainty of the measurement. While the number and unit are explicitly represented when a quantity is written, the uncertainty is an aspect of the errors in the measurement results.

Measurement: Derived Units

The International System of Units or SI system, by international agreement, has fixed measurement units for seven fundamental properties: length, mass, time, temperature, electric current, amount of substance, and luminosity. These are called the SI base units.

Center of Gravity
6.6K
The center of gravity (COG) of an object is the point where the object's total weight is considered to be concentrated. Knowing the location of the center of gravity is useful when predicting the behavior of a moving object or designing static structures. In a uniform gravitational field, the center of gravity is similar to the center of mass (COM); yet, these two points can be positioned differently. For example, the Moon's center of mass lies very close to its geometric center, but...

Center of Gravity
2.1K
The center of gravity is the point at which an object's weight appears to be concentrated and can be used to balance the object perfectly. This point is essential in mechanics as it provides information regarding a body's stability and moments of inertia. The center of gravity does not always have to fall within the shape or boundaries of the body; it may also lie outside the body in certain cases.
To determine its location, the principle of moments can be utilized by dividing the object into...

Center of Mass

The center of mass is the point at which the total mass of an object can be said to be concentrated. It is a fundamental principle in mechanics and physics that applies to all objects regardless of their shape or size. The center of gravity is the point at which an object’s weight appears to be concentrated and can be used to balance the object perfectly.
The knowledge of the center of mass can also help us to describe and predict the motion of objects. For example, when a ball is thrown...
