まとめ
血管図陰性下頭下出血 (SAH) は多様です. 出血パターンは,合併症や遅れた血管病変の検出に影響を与え,より良い患者のアウトカムのためにパーソナライズされた監視をガイドします.
科学分野:
- 神経学 神経学とは
- 神経外科は神経外科です.
- 放射線学 放射線学
背景:
- 血管図陰性サブアラクノイド出血 (SAH) は自発的なSAHの15%を占めています.
- アンジオグラム陰性SAHの監視慣行と重複血管イメージングプロトコルは矛盾しています.
- 出血のパターン,臨床的合併症,および血管損傷の遅延検出の間の関係は不明である.
研究 の 目的:
- 血管図陰性サブアラクノイド出血患者の臨床結果を体系的にレビューし,分析する.
- 出血パターンと臨床的合併症の関連性を調査する.
- 出血パターンを基に血管損傷の遅延検出の収率を評価する.
主な方法:
- PRISMAのガイドラインに従った体系的なレビューとメタ分析.
- アンジオグラム陰性SAHの臨床結果を報告した研究を含む.
- ランダム効果の一般的な線形混合モデルが,出血パターン (周周頭脳,非周頭脳,拡散,凸性) によって層分かれ,結果のプールに使用されます.
主要な成果:
- 5,921人の患者を含む67件の研究から得られたデータを分析した.
- 好ましい機能的アウトカム (3-6ヶ月) は,すべてのパターンで高い (95-97%) でした.
- 再出血率は低い (1-3%) でした. 臨床的血管 espasm (3-13%) と急性水頭症 (7-44%) はパターンによって著しく変化しました.
- 82の血管病変が再検査で確認された (脳卒中後7日以上に行われた),主に非perimesencephalic SAHで確認された.
結論:
- 血管図陰性SAHは,臨床的に有意な異質性を示しています.
- 出血パターンは,明確な合併症プロファイルと,遅延した血管損傷の検出率の変動と相関しています.
- 出血パターンは,個別化された監視戦略に情報を与えることができますが,イメージングの間隔を最適化するために将来的な研究が必要です.

In statistics, several tools are used to interpret the data. Measures of central tendency represent the characteristics of the data, such as mean, median, and mode. Additionally, measures of variance like standard deviation and range are used to find the spread of data from the mean. Relative standing measures the distance between data locations. Commonly used measures of relative standings are percentile, z score, and quartiles.

Data are individual items of information obtained from a population or sample. Data may be classified as qualitative (categorical), quantitative continuous, or quantitative discrete. Because it is not practical to measure the entire population in a study, researchers use samples to represent the population. A random sample is a representative group from the population chosen by using a method that gives each individual in the population an equal chance of being included in the sample. Random...

Predicting Reaction Outcomes
11.0K
Kinetics describes the rate and path by which a reaction occurs. In contrast, thermodynamics deals with state functions and describes the properties, behavior, and components of a system. It is not concerned with the path taken by the process and cannot address the rate at which a reaction occurs. Although it does provide information about what can happen during a reaction process, it does not describe the detailed steps of what appears on an atomic or a molecular level. On the other hand,...

Random and Systematic Errors
15.4K
Scientists always try their best to record measurements with the utmost accuracy and precision. However, sometimes errors do occur. These errors can be random or systematic. Random errors are observed due to the inconsistency or fluctuation in the measurement process, or variations in the quantity itself that is being measured. Such errors fluctuate from being greater than or less than the true value in repeated measurements. Consider a scientist measuring the length of an earthworm using a...

Directing Effect of Substituents: meta-Directing Groups
6.1K
Substituents on the benzene ring that direct an incoming electrophile to undergo substitution at the meta position are called meta directors. All meta directors either have a positive charge on the atom directly bonded to the ring or a partial positive charge. These groups function by withdrawing electrons from the ring through inductive and resonance effects. Consider the carbocation intermediates formed upon the addition of an electrophile on nitrobenzene at the...

Systematic Sampling Method
13.4K
Sampling is a technique to select a portion (or subset) of the larger population and study that portion (the sample) to gain information about the population. Data are the result of sampling from a population. The sampling method ensures that samples are drawn without bias and accurately represent the population. Because measuring the entire population in a study is not practical, researchers use samples to represent the population of interest.
