概括
在RESIST试验中,远程缺血调节 (RIC) 没有改善中风的结果,无论医院前治疗的持续时间如何. 这表明,在入院前不到一个小时内服用RIC可能不会有效.
科学领域:
- 神经学 神经学
- 心血管医学 心血管医学
- 紧急医疗 紧急医疗
背景情况:
- 远程缺血调节 (RIC) 是一种潜在的神经保护性治疗急性中风.
- 之前的研究,包括RESIST试验,发现医院前启动的RIC并没有改善90天的功能结果.
- 治疗时间可能会改变神经保护疗法的疗效.
研究的目的:
- 调查医院前远程缺血性调节 (RIC) 的持续时间是否会影响其在急性中风患者的有效性.
- 分析医院前治疗时间对中风后功能结果和神经改善的影响.
主要方法:
- 对RESIST随机对照试验 (NCT03481777) 的后期分析.
- 包括在4小时内出现了医院前中风症状的患者,随机分配到RIC或假.
- 从随机化到入院的时间 (医院前治疗持续时间) 的患者分层. 主要结局:90天修改的兰金度表 (mRS) 的变化.
主要成果:
- 在90天的mRS,mRS 0-2或24小时神经改善 (NIHSS) 上,RIC在治疗持续时间层中没有显著的益处.
- 这一发现适用于综合性急性缺血性中风 (AIS) 和脑内出血 (ICH) 患者群体.
- 对于任何结果,没有观察到RIC和医院前治疗持续时间之间的显著相互作用.
结论:
- 在RESIST试验中,更长的医院前治疗时间并没有提高RIC疗效,即使是接受再输液治疗的AIS患者.
- 这些发现表明,医院前RIC可能不会提供持续时间相关的好处,特别是当使用时间少于一个小时时.
- 结果可能无法将其推广到具有较长常规RIC施用周期的设置中.

Hospitals provide inpatient and outpatient services. Inpatient services provide care to patients that stay in the hospital for an extended period, ranging from days to months. Examples of inpatient services include intensive care units, hospital wards, or surgeries. Outpatient services provide care to patients who come to a hospital for a diagnostic or treatment but do not stay overnight —for example, diagnostic tests, surgical procedures, or health education.

Treatment Resistant Cancers
3.8K
Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...

Hospitals offer medical and surgical care to the sick and injured, along with accommodation while they recover. At the same time, they also provide outpatient, emergency, psychiatric, and rehabilitation services to meet various community needs. In addition to providing medical care, hospitals also act as hubs for medical research and training. Hospitals use clinical procedures and evidence-based practice standards to deliver patient care. To deliver safe and efficient care, a nurse must stay up...

Clinical Trials: Overview
4.9K
Clinical development focuses on how the drug will interact with the human body and encompasses four key phases of clinical trials, each serving a specific purpose in assessing the safety and effectiveness of new drugs. These phases overlap and build upon one another. Phase I involves a small group of healthy volunteers (typically 20-80 individuals) or, in cases where significant toxicity is expected, patients with the targeted disease, such as cancer or AIDS. The volunteers are tested for...

Trial and Error and Algorithm
407
A problem-solving strategy is a plan of action used to find a solution. Different strategies have distinct action plans. Trial and error involves trying different solutions until one works. For instance, to fix a broken printer, you might check ink levels, ensure the paper tray isn't jammed, and verify the printer's connection to your laptop. This method can be time-consuming but is commonly used. Thomas Edison, for example, used trial and error to find a suitable filament for the light...

Self-efficacy is the belief in one's capacity to organize and execute actions necessary to manage prospective situations. This belief significantly influences how individuals approach goals, tasks, and challenges across different domains of life.Psychological and Educational ImpactsIndividuals with strong self-efficacy are more resilient in the face of difficulties. They are more likely to adopt effective problem-solving strategies, persist through obstacles, and regulate emotions such as...
