まとめ
スポーツ活動に関連することが多い若年成人における膝関節脱臼は、症例数が増加しているものの、人口あたりの発生率は減少しています。転倒が主な原因であり、男性のリスクが高くなっています。
背景:
- 膝関節脱臼は、長期的な障害につながる可能性のある重傷です。
- Global Burden of Disease(GBD)フレームワークには、特定のスポーツ傷害のカテゴリーがありません。
- 若年成人における膝関節脱臼の負担に対する運動関連メカニズムの影響は不明です。
研究 の 目的:
- GBDデータを用いて、1990年から2021年までの若年成人における膝関節脱臼の世界的な負担を推定すること。
- 膝関節脱臼の発生率および有病率の長期的な傾向を分析すること。
- 運動関連のメカニズム(転倒、機械的力)と他の外的原因を比較すること。
主な方法:
- 20歳から40歳の成人(1990年から2021年)における膝関節脱臼のGBD 2021データを二次分析しました。
- 転倒およびその他の機械的力といった外的原因カテゴリーを用いて運動プロキシを定義しました。
- 年齢調整発生率を算出し、対数線形回帰を用いて時間的パターンを分析しました。
主要な成果:
- 膝関節脱臼の発生率の症例数は、全体的および運動プロキシの両方で増加しました。人口加重発生率および有病率の割合は1990年から2021年にかけて減少しました。男性はより高い発生率および有病率を示し、転倒がプロキシ症例の大部分を占めました。
結論:
- 若年成人は、しばしば運動外傷に関連する膝関節脱臼の大きな負担を負っています。
- 症例数は増加しているにもかかわらず、人口あたりの発生率は減少し、転倒が主なメカニズムとなっています。
- 定義されたプロキシ法は、特定のスポーツ傷害データが不足している運動関連膝関節脱臼を追跡するための信頼できる方法を提供します。

Types of Global Positioning System Surveys
362
GPS surveying methods vary in application, accuracy, and data collection techniques, catering to diverse surveying and mapping needs. Static GPS, kinematic GPS, and real-time kinematic (RTK) surveying are widely used. Each technique offers distinct advantages.Static GPS involves placing one receiver at a known reference point and another at the target point. It collects exact positional data by observing multiple satellite ranges over an extended period, achieving centimeter-level accuracy for...

Classification of Titrimetric Analysis Based on Reaction Types
1.5K
Titrimetric analysis in solution chemistry involves measuring the volume of solutions and is often called volumetric analysis. The standard solution of known concentration in the burette is called the titrant, whereas the solution of unknown concentration in the flask is called the analyte, or titrand. Titrimetric analyses can be classified into four types based on the reactions between the titrant and analyte.

Global Climate Change
28.8K
Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.

Knee Joint
3.1K
The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris...

Adult Stem Cells
33.4K
Stem cells are undifferentiated cells that divide and produce more stem cells or progenitor cells that differentiate into mature, specialized cell types. All the cells in the body are generated from stem cells in the early embryo, but small populations of stem cells are also present in many adult tissues including the bone marrow, brain, skin, and gut. These adult stem cells typically produce the various cell types found in that tissue—to replace cells that are damaged or to continuously...

Introduction to Global Positioning System
490
The Global Positioning System (GPS) revolutionized positioning on Earth, providing precise location data through satellite ranging. The GPS system was developed in 1978 by the U.S. Department of Defense for military use, and it became available for civilian applications in 1983, transforming fields including navigation, fleet management, and time synchronization for telecommunications systems.GPS consists of satellites in medium Earth orbit, about 20,200 kilometers above the surface,...
