まとめ
最低侵襲性臓二管切除術 (MIPD) は,高容量センターでの開診手術と比べて,安全性と腫瘍学的結果が比較可能であることを示しています. しかし,減血などのメリットは,特にロボットによるアプローチでは,より長い手術時間とより高いコストと相殺する必要があります.
科学分野:
- 外科腫瘍学外科腫瘍学
- 胃腸内科 胃腸内科
- 最低侵襲外科手術です.
背景:
- 腹腔鏡手術 (LPD) とロボット手術 (RPD) を含む最小侵襲性臓二管切除術 (MIPD) は,オープン臓二管切除術 (OPD) に対する新たな代替手段である.
- 技術の進歩にもかかわらず,安全性,再現性,および腫瘍学的妥当性に関する懸念は依然として存在しています.
- ランダム化対照試験 (RCT) は,MIPDの真の利点と限界を評価するための高レベルの証拠を提供します.
研究 の 目的:
- MIPD (LPD,RPD) とOPDを比較した利用可能なすべてのRCTから得られた結果を統合する.
- 死亡率,発症率,手術中のパラメータ,手術後の回復,腫瘍学的結果,変換率,およびコストを含む主要な領域を評価する.
- メタアナリシスを行うよりも,MIPDのメリットと限界に関するRCTの発見を文脈化するために.
主な方法:
- OPDとLPDとRPDを比較したすべての発表されたRCTのナレーションレビュー.
- 分析は,死亡率,重症度,手術中の失血 (IBL),入院期間 (LOS),腫瘍学的結果,転換率,および費用に焦点を当てた.
- 外科医の経験の考慮と,結果に対する機関容量の影響.
主要な成果:
- LPDは,大容量のセンターで,IBLが低下し,LOSが短縮され,OPDと比較できる死亡率と罹患率を示しています.
- RPDの結果は混在しており,一部の試験では回復が改善されたが,他の試験では高発性胞 (POPF) と遅れた胃排泄 (DGE) が報告され,コストも増加した.
- LPDとRPDの両方が,OPDと同等の腫瘍学的アウトカムを達成し,LPDは長期的な非劣等性を示しています.
- MIPDの稼働時間は長く,変換率は学習曲線効果を示しています.
結論:
- 現在のRCTのエビデンスは,MIPDは,経験豊富な外科医が専門の,大量のセンターで安全で,実行可能で,腫瘍学的に健全であることを支持しています.
- IBLの減少とより迅速な回復の利点は,より長い運用時間,変換リスク,より高いコスト (特にRPD) とバランスをとらなければなりません.
- MIPDは,普遍的な標準ではなく,構造的なトレーニング,患者の選択,および制度的準備を必要とする高度なオプションです.

Matrix-assisted laser desorption ionization (MALDI) is a powerful analytical technique used in mass spectrometry. It enables the identification and characterization of various biomolecules, including proteins, peptides, nucleic acids, and carbohydrates. MALDI is an ionization technique, widely employed in biological and medical research, as well as in fields like pharmacology and biochemistry.The analyte of interest, a biomolecule or a mixture of biomolecules, is mixed with a suitable matrix...

Bystander Effect

The discussion of bullying highlights the problem of witnesses not intervening to help a victim. This is a common occurrence, as the following well-publicized event demonstrates. In 1964, in Queens, New York, a 19-year-old woman named Kitty Genovese was attacked by a person with a knife near the back entrance to her apartment building and again in the hallway inside her apartment building. When the attack occurred, she screamed for help numerous times and eventually died from her stab wounds.

Protein Complex Assembly
16.9K
Proteins can form homomeric complexes with another unit of the same protein or heteromeric complexes with different types. Most protein complexes self-assemble spontaneously via ordered pathways, while some proteins need assembly factors that guide their proper assembly. Despite the crowded intracellular environment, proteins usually interact with their correct partners and form functional complexes.

RNA Splicing

Splicing is the process by which eukaryotic RNA is edited before its translation into protein. The RNA strand transcribed from eukaryotic DNA is called the primary transcript. The primary transcripts that become mRNAs are called precursor messenger RNAs (pre-mRNAs). Eukaryotic pre-mRNA contains alternating sequences of exons and introns. Exons are nucleotide sequences that code for proteins, whereas introns are the non-coding regions. In RNA splicing, introns are removed and exons are bonded...

Self-Evaluation: Self-Enhancement and Self-Verification

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...
