まとめ
この研究では、唾液微生物叢データを使用して、口腔扁平上皮癌(OSCC)の非侵襲的な診断モデルを開発した。機械学習モデルはOSCCを正確に特定し、臨床応用におけるモデル選択の重要性を強調した。
科学分野:
- 微生物叢研究
- 口腔腫瘍学
- 診断バイオマーカー
背景:
- 口腔扁平上皮癌(OSCC)における唾液微生物叢の役割がますます認識されている。
- 既存の研究には、コホート間研究やOSCCの非侵襲的診断モデルが不足している。
- OSCCに対する堅牢で非侵襲的な診断アプローチが必要とされている。
研究 の 目的:
- OSCC患者と健常者の唾液微生物組成の違いを調査すること。
- 唾液微生物叢データを使用して、OSCCのコホート間非侵襲的診断モデルを開発および検証すること。
- 様々な機械学習モデルの診断パフォーマンスを評価すること。
主な方法:
- 665人(OSCC患者311人、健常対照354人)のコホート間唾液微生物叢データを解析した。
- OSCC患者で有意に変化した微生物を同定した。
- OSCC診断のための機械学習モデル(ランダムフォレスト、エクストラツリーズ、勾配ブースティング、XGBoost)を構築および検証した。
主要な成果:
- OSCC患者と健常者の唾液微生物組成に有意な差が観察された。
- OSCC患者では、7つの特定の微生物が減少し、7つの微生物が増加していた。
- 機械学習モデルは、属および種レベルの両方で高い診断精度(AUC 63.1%–96.9%)を達成した。
結論:
- 唾液微生物叢データを使用して、OSCCの堅牢で非侵襲的な診断モデルが達成可能である。
- 分類学的解像度に関係なく高い診断精度が得られ、モデル選択が強調される。
- 機械学習モデルの選択は、OSCC診断における臨床応用にとって重要である。

Oral Cavity
3.0K
The oral cavity, or the mouth, is a complex structure in humans that plays a vital role in our day-to-day lives. Its role is not only in chewing and swallowing food; it also plays a role in speech and facial expressions.
Teeth: The teeth are the hardest structures in our bodies. Humans have two sets of teeth throughout their lifetime: deciduous (baby) teeth and permanent teeth. Each tooth consists of several parts: the crown (visible part), the root (embedded in the jaw), enamel (hard outer...

Oral Hypoglycemic Agents: Glinides
608
Repaglinide (Prandin) and Nateglinide (Starlix), known as glinides, are oral insulin secretagogues that stimulate insulin release from pancreatic β cells by closing the ATP-sensitive potassium channels (KATP channel). Repaglinide controls insulin release from pancreatic β cells by managing potassium efflux. It shares two binding sites with sulfonylureas and also has a unique site, indicating overlapping mechanisms of action. With a rapid onset and a 4-7 hour duration, it effectively...

Psychosexual Stages of Personality: Oral
2.9K
The oral stage is the initial phase of Sigmund Freud's theory of psychosexual development, occurring from birth to approximately 12 to 18 months. During this period, the infant's mouth serves as the primary source of pleasure, with actions such as sucking, chewing, biting, and drinking playing a crucial role in reducing tension. These activities are essential not only for nourishment but also for the infant's psychological and emotional satisfaction.

Oral Hypoglycemic Agents: Sulfonylureas
834
Sulfonylureas are oral hypoglycemic agents utilized in treating type 2 diabetes. They are characterized by their unique sulfonylurea chemical structure. The family of sulfonylureas is divided into generations. First-generation sulfonylureas, including tolbutamide (Orinase), chlorpropamide (Diabinese), and tolazamide (Tolinase), trigger insulin release from pancreatic β cells and enhance peripheral tissues' insulin sensitivity. The second-generation members, such as glipizide...

Assessing Body Temperature - Oral
1.5K
Here are the steps to accurately measure oral temperature using an electronic thermometer:
Step 1:
Start by practicing proper hand hygiene to prevent the spread of microorganisms.
Step 2:
Take the thermometer out of the charging unit, switch it on, and wait for the ready sign.
Step 3:
Gently slide the probe cover until a click is heard. This simple action prevents cross-contamination and ensures the correct placement of the probe cover.
Step 4:
Instruct the patient to open their mouth and place...

Non-Oral Extravascular Drug Absorption Routes
504
Non-oral extravascular routes, which encompass sublingual, buccal, topical, intramuscular, and inhalation methods, primarily utilize passive diffusion to transport drugs into the systemic circulation. The absorption rates and effectiveness of these routes depend on the drug's physicochemical properties, as well as the patient's anatomical and pathophysiological state.
Lipophilic drugs that are stable at salivary pH (6) and exhibit minimal binding to the oral mucosa are absorbed more...
