概括
心脏手术会改变肠道微生物群,增加感染和炎症的风险. 调节肠道细菌可能会改善结果,但需要更多的研究来理解这些复杂的相互作用.
科学领域:
- 微生物组研究
- 心血管科学
- 炎症生物学
背景情况:
- 心脏外科手术,特别是心肺绕道手术 (CPB),会带来SIRS,POAF和感染等术后并发症的重大风险.
- 肠心轴,包括肠道屏障完整性和微生物群,越来越多地被认为是影响这些手术结果的因素.
研究的目的:
- 检查心脏手术患者的肠道微生物组成与炎症反应之间的关系.
- 评估这些微生物变化如何影响心脏手术后的临床结果.
主要方法:
- 对心脏手术患者的肠道微生物群变化和炎症标志物的系统审查.
- 关键微生物代谢物 (SCFA,TMAO,BA) 的分析及其与炎症和结果的关联.
- 包括维生素D状态作为潜在的调节因子.
主要成果:
- 心脏外科手术总是引发显著的手术前肠道失调,受益细菌的减少 (例如,蓝斑,便细菌) 和病原体的增加所标志.
- 在没有明显并发症的情况下,炎症生物标志物升高在术后是常见的.
- 微生物代谢物和维生素D缺乏与炎症和POAF发生率的增加有关.
结论:
- 手术前的肠道微生物可能会影响术后炎症反应的严重程度.
- 术后肠道微生物群调节是改善心脏手术结果的潜在策略.
- 进一步进行大规模标准化研究至关重要,以澄清相互作用并指导干预措施,考虑到抗生素使用等混因素.

Inflammatory Bowel Disease V: Surgical Management
917
Surgical interventions for inflammatory bowel disease (IBD), which includes ulcerative colitis and Crohn's disease, are essential in managing symptoms and addressing complications. The selection of surgical procedures is contingent upon the specific conditions and complications that stem from these illnesses.
Here are some common surgical interventions for IBD:

Cardiomyopathy VII: Pre and Post Operative Nursing Management
460
Patients with hypertrophic cardiomyopathy (HCM) and left ventricular outflow tract (LVOT) obstruction who remain symptomatic despite optimal medical therapy may undergo a septal myectomy (Morrow procedure). This procedure involves excising a portion of the hypertrophied septum below the aortic valve using a heart-lung machine to improve blood flow through the LVOT. Effective preoperative and postoperative nursing management ensures successful patient outcomes, minimizes complications, and...

Introduction to the Human Microbiota
209
Microorganisms colonize various regions of the human body, including the mouth, nasal passages, throat, stomach, intestines, urogenital tract, and skin. The total number of microbial cells is estimated to range from 10¹³ to 10¹⁴—comparable to, or exceeding, the number of human somatic cells. This host–microbiome relationship has led to the conceptualization of humans as supraorganisms, wherein microbial communities perform vital roles in development, immunity,...

The Oral Microbiota
90
The oral microbiome includes a complex ecosystem comprising over 700 microbial species, identified through genomic sequencing and culture-based analyses to date. This community includes a core microbiome, found universally among individuals, and a variable component influenced by environmental factors such as diet, lifestyle, and host genetics. Site-specific conditions, including oxygen gradients, pH levels, and nutrient availability, determine the spatial distribution of these microorganisms...

Functions of the Gut Microbiota
233
The gut microbiota includes trillions of microorganisms that colonize the human gastrointestinal tract, including bacteria, archaea, viruses, and fungi. This complex ecosystem plays a critical role in maintaining intestinal and systemic health. Most of these microbes inhabit the large intestine, establishing a relatively stable and diverse community that contributes to gut homeostasis through various metabolic, immunological, and protective mechanisms.Dominant bacterial phyla, such as...

Gut-Brain Axis
222
The gut–brain axis is a bidirectional communication system that connects the gastrointestinal tract and the brain. This interaction is mediated through multiple pathways, including the vagus nerve, hormonal signals, immune responses, and chemical messengers produced by gut microbes.Microbial Contributions to Brain FunctionGut microbiota contributes significantly to brain function by producing neuroactive compounds. These include neuroactive compounds that influence neurotransmitters such...
