まとめ
新しい大規模言語モデル（LLM）チャットボットであるPreassessment（PreA）は、専門医の診察時間を大幅に短縮し、ケアの連携を改善しました。地域関係者とLLMを共同設計することで、ヘルスシステムと患者中心のケアが向上します。
科学分野:
- ヘルスインフォマティクス; 医療における人工知能; 臨床意思決定支援
背景:
- 一次医療から専門医へのケア移行は、しばしば非効率性を伴います。; 患者向けの С（LLM）は、これらのプロセスを効率化する可能性を提供します。; 効果的なLLMアプリケーションの開発には、地域のヘルスケアの文脈を慎重に考慮する必要があります。
主な方法:
- 24の医療分野にわたる2,069人の患者と111人の専門医を対象にランダム化比較試験を実施しました。; 患者はPreAのみ、PreAと人間のサポート、またはPreAなしのグループに割り当てられました。; 主な評価項目は、医師の診察時間、医師が認識するケア連携、患者が報告するコミュニケーションの容易さでした。
結論:
- PreAのような共同設計されたLLMは、ヘルスケアの移行を効果的に効率化し、患者ケアを改善することができます。; ステークホルダーとの共同設計は、特にリソースが限られた状況において、受動的なデータ収集と比較してLLM展開のための優れた戦略です。; 自律的なLLM運用は、ヘルスシステムの効率性と患者中心のケアを向上させるために実行可能であり、有益です。

146.3K
The chemical and physical properties of plasma membranes cause them to be selectively permeable. Since plasma membranes have both hydrophobic and hydrophilic regions, substances need to be able to transverse both regions. The hydrophobic area of membranes repels substances such as charged ions. Therefore, such substances need special membrane proteins to cross a membrane successfully. In facilitated transport, also known as facilitated diffusion, molecules and ions travel across a...

22.7K
Whether solid, liquid, or gas, a substance's state depends on the order and arrangement of its particles (atoms, molecules, or ions). Particles in the solid pack closely together, generally in a pattern. The particles vibrate about their fixed positions but do not move or squeeze past their neighbors. In liquids, although the particles are closely spaced, they are randomly arranged. The position of the particles are not fixed—that is, they are free to move past their neighbors to...

36.0K
Not all intergroup interactions lead to negative outcomes. Sometimes, being in a group situation can improve performance. Social facilitation occurs when an individual performs better when an audience is watching than when the individual performs the behavior alone. This typically occurs when people are performing a task for which they are skilled.

02:58Properties of Transition Metals
29.6K
Transition metals are defined as those elements that have partially filled d orbitals. As shown in Figure 1, the d-block elements in groups 3–12 are transition elements. The f-block elements, also called inner transition metals (the lanthanides and actinides), also meet this criterion because the d orbital is partially occupied before the f orbitals.

01:58Cooperative Allosteric Transitions
8.6K
Cooperative allosteric transitions can occur in multimeric proteins, where each subunit of the protein has its own ligand-binding site. When a ligand binds to any of these subunits, it triggers a conformational change that affects the binding sites in the other subunits; this can change the affinity of the other sites for their respective ligands. The ability of the protein to change the shape of its binding site is attributed to the presence of a mix of flexible and stable segments in the...

01:16Facilitated Diffusion
1.2K
The plasma membrane, a critical structure in cellular biology, houses an array of transporters, or carrier proteins, interspersed within its lipid bilayer. These proteins play a crucial role in solute transport through facilitated diffusion, a form of passive diffusion that uses transporters to move the molecules across the membrane.
In this process, substrates such as organic compounds and ions interact with a transporter on one side, triggering conformational changes in proteins that enable...
