- 临床试验 临床试验
- 现实世界的数据分析.
背景情况:
- 现实世界数据 (RWD) 在单臂临床试验中越来越多地被用作外部对照.
- 在使用RWD时存在方法上的挑战,需要验证RWD控制队列.
- 急性髓性白血病 (AML) 是一种严重的血液性恶性瘤.
研究的目的:
- 为了验证来自RWD的两个外部对照队伍与随机对照试验 (RCT) 进行对比.
- 评估RWD对照队伍的可比性,以便将来在比较分析中使用.
- 评估数据完整性和患者特征对RWD队列有效性的影响.
主要方法:
- 两个RWD队列 (HARMONY联盟和荷兰癌症注册) 与HOVON-103试验的对照组进行比较.
- 包括新诊断的65岁以上的AML患者接受标准诱导化疗.
- 应用1:1倾向得分校准匹配 (PSM) 来提高队列可比性.
- 评估整体存活率 (OS) 和无复发存活率 (RFS).
主要成果:

External and Internal Respiration
7.2K
External respiration occurs in the lungs, and it is the first step in the journey of oxygen inside the body. When we inhale, oxygen enters our lungs and diffuses across the thin alveolar membrane. The alveoli are tiny, air-filled sacs that provide a vast surface area for gas exchange. Oxygen in the alveoli has a higher partial pressure (105 mmHg) than in the adjacent pulmonary capillaries (40 mmHg), establishing a pressure gradient. As a result, oxygen molecules move from the alveoli into the...

Internal and External Forces
16.1K
Newton's first law states that a net external force causes a change in motion. External forces act on an object or system, originating outside of the object or system. In contrast, internal forces originate inside the system of interest and do not lead to any acceleration. In simpler words, internal forces are forces that act on one part of an object and are exerted by another part of the same object. External forces are forces that act on an object due to some other object. Therefore, when...

Patient-centered Care
2.9K
Patient-centered care involves delivering care beyond inpatient hospitalization. Reflective practice can enhance a patient-centered approach. Reflective practice is a process of reasoning that considers all aspects of the present situation, including practicalities, learning from personal practice, and consideration of patient needs. Patients appreciate care decisions made while considering their input. Involving the patient in their care provides the patient with a sense of contribution rather...

Drug Dosing: Obese Patients
235
In the United States, obesity is a prominent concern. It is linked to heightened mortality rates due to increased occurrences of conditions such as hypertension, atherosclerosis, coronary artery disease, and diabetes compared to nonobese individuals. A patient is classified as obese if their actual body weight surpasses the ideal or desirable body weight by 20%, based on Metropolitan Life Insurance Company data. Ideal body weights consider average weights and heights for males and females...

Drug Dosing: Geriatric Patients
229
Elderly individuals encompass a diverse population with varying degrees of age-related physiological changes. Defining the elderly presents challenges, as the geriatric population is often arbitrarily categorized as individuals older than 65. However, many individuals in this group lead active and healthy lives, with an increasing number surpassing 85 years and falling into the older elderly category. Physiological changes associated with aging impact performance capacity and homeostatic...

Drug distribution in the pediatric population exhibits unique challenges and considerations due to the physiological differences between children, particularly neonates and infants, and adults. A crucial aspect of pediatric pharmacology is understanding how these differences impact the pharmacokinetics of various drugs, necessitating age-specific dosing strategies to ensure efficacy and safety.Neonates and infants have a higher total body water content, ~75%–90% of their body weight,...
