概括
最少侵入性胰腺二管切除术 (MIPD) 的安全性和瘤学结果与大体积中心的开放手术相提并论. 然而,像减少血液流失这样的好处必须与更长的手术时间和更高的成本进行权衡,特别是在机器人方法中.
科学领域:
- 手术瘤学手术瘤学
- 胃肠病学 胃肠病学
- 最少侵入性的手术
背景情况:
- 最少侵入性胰腺二切除术 (MIPD),包括腹腔镜 (LPD) 和机器人 (RPD),是开放性胰腺二切除术 (OPD) 的新兴替代方案.
- 尽管技术进步,但安全性,可复制性和瘤学适度的担忧仍然存在.
- 随机对照试验 (RCT) 提供了高水平的证据来评估MIPD的真正好处和局限性.
研究的目的:
- 综合所有可用的RCT的发现,将MIPD (LPD和RPD) 与OPD进行比较.
- 评估关键领域,包括死亡率,发病率,手术内参数,术后恢复,瘤学结果,转化率和成本.
- 将RCT发现的MIPD的好处和局限性置于背景,而不是进行元分析.
主要方法:
- 对所有已发表的RCT进行叙述审查,将LPD和RPD与OPD进行比较.
- 分析的重点是死亡率,重大发病率,手术内流血 (IBL),停留时间 (LOS),瘤学结果,转化率和成本.
- 考虑外科医生的经验和机构体积对结果的影响.
主要成果:
- 在高体积中心,LPD的死亡率和发病率与OPD相似,IBL减少,LOS短.
- RPD的结果是混合的,一些试验显示了改善的恢复,但另一些试验报告了更高的胰腺抽 (POPF) 和延迟胃排空 (DGE) 率,以及成本增加.
- 无论是LPD还是RPD,都达到与OPD相当的瘤结果,而LPD显示长期非劣势.
- 对于MIPD,操作时间更长,转换率表明学习曲线效应.
结论:
- 目前的RCT证据支持MIPD是安全的,可行的,在经验丰富的外科医生的专业化,大体积的中心,在瘤学上是健全的.
- 减少IBL和更快恢复的好处必须与更长的操作时间,转换风险和更高的成本 (特别是RPD) 相平衡.
- MIPD是一种先进的选择,需要结构化培训,患者选择和机构准备,而不是通用标准.

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
60.7K
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...

Voluntary behavior with the intent to help other people is called prosocial behavior. Why do people help other people? Is personal benefit such as feeling good about oneself the only reason people help one another?

Self-Evaluation: Self-Enhancement and Self-Verification
5.8K
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...
