概括
针对道导管 (TC) 的专用协议显著减少了与TC相关的血液感染 (TC-BSI),主要是由Staphylococcus epidermidis引起的. 这种方法为血液透析患者提供了安全的血管接入选择,TC-BSI死亡率低,对长期存活没有负面影响.
科学领域:
- 腎臟病學 (nephrology) 是一種醫學專業.
- 传染性疾病 传染性疾病
- 血管外科 血管外科
背景情况:
- 道导管 (TC) 对于血液透析 (HD) 是至关重要的,但具有感染,发病率和死亡的风险.
- 关于预防TC相关感染的最佳预防措施的数据有限,因为样本规模小,随访时间短.
研究的目的:
- 为了鉴定TC患者的特征,确定TC相关血流感染 (TC-BSI) 的发生率和原因.
- 评估植入前预防措施对TC-BSI和长期随访患者存活率的影响.
主要方法:
- 在第三级护理医院对381名患有462个TC植入物的患者 (2005-2019) 的回顾性研究.
- 协议包括:金黄色葡萄球菌携带者查/治疗,赫西丁浴和抗生素预防.
- 长期随访至2020年12月31日,用于TC-BSI和患者存活率.
主要成果:
- 低TC-BSI发病率 (0.36每1000个TC-days),主要是格拉姆阳性 (83.4%),主要是表皮球菌 (42.4%) 和金黄色菌 (28.0%).
- 大多数感染 (80%) 发生在六个月后;只有4.7%在30天内发生.
- 感染是死亡的主要原因 (31.1%),但只有2.1%的死亡直接与TC-BSI有关.
结论:
- 一个专门的TC植入方案导致了较低的TC-BSI发病率,晚发感染主要是由S. epidermidis引起的.
- 系统的金黄色细菌查和去殖民化减少了由这种病原体引起的TC-BSI,而不会增加MRSA菌株.
- TC使用表明TC-BSI相关的死亡率较低,并且不会影响整体5年生存率,支持其在选定的HD患者中使用.

Predicting Reaction Outcomes
10.4K
Kinetics describes the rate and path by which a reaction occurs. In contrast, thermodynamics deals with state functions and describes the properties, behavior, and components of a system. It is not concerned with the path taken by the process and cannot address the rate at which a reaction occurs. Although it does provide information about what can happen during a reaction process, it does not describe the detailed steps of what appears on an atomic or a molecular level. On the other hand,...

Outcomes of Glycolysis
106.8K
Nearly all the energy used by cells comes from the bonds that make up complex organic compounds. These organic compounds are broken down into simpler molecules, such as glucose. As a result, cells extract energy from glucose over many chemical reactions—a process called cellular respiration.
Cellular respiration can occur aerobically (with oxygen) or anaerobically (without oxygen). In the presence of oxygen, cellular respiration starts with glycolysis and continues with pyruvate...

Long-term Depression
33.2K
Long-term depression, or LTD, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTD is the process of synaptic weakening that occurs over time between pre and postsynaptic neuronal connections. The synaptic weakening of LTD works in opposition to synaptic strengthening by long-term potentiation (LTP) and together are the main mechanisms that underlie learning and memory.

Guidelines for Writing Outcome
3.7K
When developing expected outcomes for a patient care plan, the nurse should adhere to the following recommendations:
Patient outcomes reflect the patient's response to the goal rather than what the nurse aims to achieve. Terminology should be observable and measurable to avoid the reader's interpretation. The desired outcome should be realistic and achievable in the designated care timeframe. Expected outcomes should align with adjunctive therapies. The outcome should enhance care...

Directional Terms
16.1K
Directional terms are essential for describing the relative locations of different body structures. For instance, an anatomist might describe one band of tissue as "inferior to" another, or a physician might describe a tumor as "superficial to" a deeper body structure. These terms often use comparative terms in pairs to trace out the relative locations of one body part to another or descriptions of body tissues like the deeper ones from superficially present with reference to...
